Crystal Report Viewer & Parameters

Hello,
I have designed a report n Crystal Reports and works on my machine fine. When I preview the report it ask me what parameters I want to search for. When I tried to view this report in Crystal Reports viewer it doesn't ask me. So I learned that I need Crystal Report Server (using 2013 for both Server and Report Writer) and now I am stuck what I need to do. I have downloaded a trail version (intent to purchase it works as I need to) of Crystal Server and used it defaults. I just need some help in direction in what I need to do on Server and Report side to make this report work on the View Side to prompt the user to enter in parameters. When I saved my report I deselected the Save Data to Report. I have tried to look for documents in what I need and came up with a road block or not sure what I really looking for. And I am sorry that I still a newbie for this software.
Thank you,
Gerald

Hi,
Try to use the parameter panel to change the parameter value of the report in the Viewer:
Open the report in Crystal Reports Designer.
Edit the parameter.
Change the Show on (Viewer) Panel value to Editable
Republish to Enterprise

Amine.

Crystal Report Viewer Credential Prompt for Report with Dynamic Parameters

The .NET Crystal Report Viewer is prompting for database credentials when launching a report containing dynamic parameters. This only occurs for reports created with SAP Crystal Reports 2011 designer. Reports created with Crystal Reports XI designer (where dynamic parameters were first introduced) work correctly.
The credential prompt window contains the following fields:
- Server Name: <server name> (disabled)
- Database Name: <database name> (disabled)
- User Name: <empty> (enabled)
- Password: <empty> (enabled)
- Use Single Signon Key: false (disabled)
The values in the prompt window which are disabled are the database connection values used during the design of the report in the SAP Crystal Reports 2011 designer.
Expected Result:
- No prompt for database credentials.
- Values read from the database should be populated in a drop down for the dynamic parameters.
Environment:
- Visual Studio 2010 (C#)
- Windows 7 Enterprise
- SAP Crystal Reports runtime engine for .NET Framework 4
- SAP Crystal Reports, version for Visual Studio 2010
- SAP Crystal Reports 2011
The database connection is being set to use a DSN. It must be a DSN as the calling application is only aware of the DSN/Username/Password values. These values are being passed to the Crystal Report Viewer contained in a Windows form.
The database connection for the report is being set as follows:
foreach (InternalConnectionInfo internalConnectionInfo in this.report.DataSourceConnections)
 // Must set the UseDSNProperties flag to True before setting the database connection otherwise the connection does not work
 if (internalConnectionInfo.LogonProperties.ContainsKey("UseDSNProperties"))
 internalConnectionInfo.LogonProperties.Set("UseDSNProperties", true);
 // Supposed to set the database connection for all objects in the report (ie. main report, tables, sub reports)
 internalConnectionInfo.SetConnection(this.DSN, string.Empty, this.LoginName, this.Password);
The SetConnection method's signature is as follows:
 SetConnection(string server, string database, string name, string password)
As you can see from the code snippet above I am setting the DSN name as the server parameter, blank for the database parameter (a database connection using DSN should only require DSN name/Username/Password) and the database username and password respectively.
Is this a SAP bug?
Is this the correct way of setting the database connection to use a DSN?
Is there some other properties that need to be set somewhere else in the report through code?
Any help would be greatly appreciated.

Thanks for the pointer to the database connection code generator. After taking a look at the output from the tool I was able to finally get the dynamic parameters to load and populate properly without prompting for credentials. I needed to tweak the outputted code a bit to match my requirements of using a DSN only connection.
Instead of updating the database connection properties contained within the Report.Database.Tables collection from the CrystalReports.Engine namespace, I changed it to replace the database connection properties in the Report.ReportClientDocument.DatabaseController.Database.Tables collection from the CrystalDecisions.ReportAppServer.DataDefModel namespace. For one reason or another, using the RAS namespace solved the problem.
Below is the updated code with the change made:
using RAPTable = CrystalDecisions.ReportAppServer.DataDefModel.Table;
foreach (InternalConnectionInfo internalConnectionInfo in this.report.DataSourceConnections)
 // Must set the UseDSNProperties flag to True before setting the database connection
 if (internalConnectionInfo.LogonProperties.ContainsKey("UseDSNProperties"))
 internalConnectionInfo.LogonProperties.Set("UseDSNProperties", true);
 // Sets the database connection for all objects in the report (ie. main report, tables, sub reports)
 internalConnectionInfo.SetConnection(this.DSN, string.Empty, this.LoginName, this.Password);
// The attributes for the QE_LogonProperties which is part of the main property bag
PropertyBag innerPropertyBag = new PropertyBag();
innerPropertyBag.Add("DSN", this.DSN);
innerPropertyBag.Add("UserID", this.LoginName);
innerPropertyBag.Add("Password", this.Password);
innerPropertyBag.Add("UseDSNProperties", "true");
// The attributes collection of the tables ConnectionInfo object
PropertyBag mainPropertyBag = new PropertyBag();
mainPropertyBag.Add("Database DLL", "crdb_ado.dll");
mainPropertyBag.Add("QE_DatabaseType", "OLE DB (ADO)");
mainPropertyBag.Add("QE_LogonProperties", innerPropertyBag);
// Pass the database properties to a connection info object
ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.Attributes = mainPropertyBag;
connectionInfo.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;
connectionInfo.UserName = this.LoginName;
connectionInfo.Password = this.Password;
// Replace the database connection properties of each table in the report
foreach (RAPTable oldTable in this.report.ReportClientDocument.DatabaseController.Database.Tables)
 RAPTable table = new RAPTable();
 table.ConnectionInfo = connectionInfo;
 table.Name = oldTable.Name;
 table.QualifiedName = oldTable.QualifiedName;
 table.Alias = oldTable.Alias;
 this.report.ReportClientDocument.DatabaseController.SetTableLocation(oldTable, table);
this.report.VerifyDatabase();
Thanks again Ludek for the help.

Crystal reports viewer will not prompt for parameters

Help,
I can not get crystal report viewer to prompt for parameters when called from IIS 8 on Server 2012 r2
I can get crystal report viewer to prompt for parameters when run from vs 2010 built in web service.

Thanks,
The solution for me was to uninstall the latest crystal reports runtime 13.10.x and install 13.6.x instead.
Thanks anyway.

Dynamic command execution fails in Crystal report viewer for parameters

We are using the Crystal Report Viewer for the .Net Application on the client side.The reports are designed using Crystal Report XI R2.
The issues that we are currently encountering is that, we are unable to load the combo-boxes in the pop-up for the parameters.
All the reports have multiple commands and the variables are of 'dynamic' type.
When the dialog box for requesting the pop-up comes up, It comes up empty even though they are linked to the respective commands.
Also,For reports having multiple parameters we are unable to give a single dialog box to get in all the parameters.It appears as a series of prompts.
Both,these issues are not encountered when the reports are launched via the Crystal reports developer tool.

Hello Varun,
I recommend to post this questionin the [dedicated NET forum|SAP Crystal Reports, version for Visual Studio;.
This forum is monitored by qualified technicians and you will get a faster response there.
Thank you for your understanding,

Crystal Report Viewer 2008, postback causes a weird QueryString for dates

HI,
I'm having a weird problem that was masked with the error "".
What is happening to me is that i have an ASPX page where the QueryString passed in is used as parameters to the report (straightforward). When the page first loads, this is all fine the QuerySTring is properly parsed and the report is properly displayed. Now, the problem comes when i click on the PRINT Button it performs a postback, and during that postback the querystring is read so that it can rebuild the report on the postback. (In previous versions of crystal, this has always worked). The issue here is that the version 12 of the report viewer here now appears to also append some information to the query string that was not previously there (like this: ServletTask=Print&cmd=get_pg&page=1) So the problem here for me is this is what my original QueryString looks like:
tokenid=b2817081-6b52-43c7-8e2c-d6209af2ed98&Type=Appointment&Val=12%3b1%3b1%3b06%2f10%2f2000
THat query string is generated by the following code (pre-encoded)
"PrintPage.aspx?tokenid=" & Guid.NewGuid.ToString & "&Type=Appointment&Val=" & "12" & ";" & "1" & ";" & "1" & ";" & "1/1/2000" (NOTE the date here, i'll get to that in a second)
Then, what the problem is on the postback the Query String looks like this:
tokenid=2a4f42de-bd90-48b5-ac82-bd34b503afd3&Type=Appointment&Type=Appointment&Val=12%3b1%3b1%3b1%2f1%2fPrintPage.aspx%3ftokenid%3d2a4f42de-bd90-48b5-ac82-bd34b503afd3&Val=12%3b1%3b1%3b1%2f1%2f2000&ServletTask=Print&cmd=get_pg&page=1
As you can see here it's all messed up.
So, what i found here is that the underlying cause is that we are passing a "date" in the original QueryString and it seems on the postback the Crystal Reports Viewer is having some issue with that and basically messes up the query string...
I have Crystal Reports 2008/SP3 installed.
Any help would be greatly appreciated.
Thanks

Cleaning up these forums I came across this unanswered thread.
Very weird behavior that I have seen maybe 3 or 4 years ago - I think it was with opendocument.aspx...
In this case, we appear to be re-adding the querystring with the aspx name and question mark (u2026.parentagesu2026). Having two question marks (%3f) is essentially a malformed URL since this indicates where the querystring starts.
The duplicate querystring may have been a coding error(?) where it gets added again on a postback.
Were you able to resolve the issue?

Crystal Report Viewer integration with Sharepoint 2010

We had a requirement in our project to view crystal report off an hyper link embedded into sharepoint web part developed using ASP .NET. The report accepted few parameters from the sharepoint page and passed those on to the SQL server to retrive data and
display the data in the report. The challenge was to open the report in the web browser.
The first difficulty was to find the right control to use, the report viewer tool that comes with Visual Studio 2010 is not the right one to use to view Crystal reports, I realised this after spending half a day trying to figure out why wouldn't the report
load. I then downloaded the Crystal Report Viewer for VS 2010 Standard from http://www.businessobjects.com/jump/xi/crvs2010/us2_default.asp. After you install this, you get the crystal report viewer in your toolbar. All you have to do is drag and drop it on
to the web part and configure it to use your report. If any one needs help with this let me know I will show how to do that.
So far so good. The biggest challenge was to deploy this on to the production server which took better part of 3 days to figure out how its done. If you deploy the WSP file as it is expecting that the crystal DLLs would be embedded in it then be ready to
expect a rude shock because it isn't. Here are the steps -
1. Deploy the WSP to the sharepoint server
2. Install the crystal dlls used in the project (CrystalDecisions.CrystalReports.Engine.dll, CrystalDecisions.ReportSource.dll, CrystalDecisions.Shared.dll, CrystalDecisions.Web.dll) into the GAC using GacUtil command
3. Add following entries to Web.Config file (C:\inetpub\wwwroot\wss\VirtualDirectories\80\web.congif)
 <SafeControl Assembly="CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.CrystalReports.Engine" TypeName="*" Safe="True" SafeAgainstScript="False"
/>
 <SafeControl Assembly="CrystalDecisions.ReportSource, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.ReportSource" TypeName="*" Safe="True" SafeAgainstScript="False" />
 <SafeControl Assembly="CrystalDecisions.Shared, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.Shared" TypeName="*" Safe="True" SafeAgainstScript="False" />
 <SafeControl Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.Web" TypeName="*" Safe="True" SafeAgainstScript="False" />
4. Install crystal redistributable package which can be downloaded from http://www.businessobjects.com/jump/xi/crvs2010/us2_default.asp (
SAP Crystal Reports runtime engine for .NET Framework 4 (64-bit))
5. Copy aspnet_client folder from C:\>inetpub\wwwroot and overwrite it on C:\>inetpub\wwwroot\wss\VirtualDirectories\80
And we are done. Fingers crossed it should all work.

Hi Mahesh,
How are you loading the report in your webpart? This is what I have done. I have tried to explain what I am doing in the program comments. Hope this helps. Good luck.

Report Document not show on Crystal Report Viewer in C#

My program is modified from VB.NET. Now I struck with Crystal Report that Crystal Report Viewer didn't show Report Document.
Printing code is composed of two forms. One assign parameters and objects need. Other is Crystal Report Viewer form, CrystalReportForm. Last one run report by parameter from the first.
When run this code that it didn't found any error but the problem is no report show on Crystal Report Viewer on second form. It just blank Crystal Report Viewer. There arm't any message response.
Here is my code.
// report caller form.
private void Print()
 CrystalReportForm rptForm = new CrystalReportForm();
 string[] strtbl;
strtbl = new string[1];
 string[] strqry;
strqry = new string[1];
 // prepare var
 string myqry;
 string myrpt;
 // Pass The Table That you used in the crystal Report
strtbl[0] = "r_receipts";
 // Pass the Query
myqry = "SELECT * FROM r_receipts";
myrpt = "rptReceipts.rpt";
strqry[0] = myqry;
 //Pass For Mdi True
rptForm.MdiParent = this.ParentForm;
rptForm.ViewReport(myrpt, strtbl, strqry, "");
 //Parameter Value It is Optional
rptForm.Show();
// Crytal Report Viewer form.
public void ViewReport(string ReportName , string[] TableName, string[] QueryString , string Parameter = "")
 //Me.MdiParent = mainpage;
 if (TableName.Length != QueryString.Length )
 MessageBox.Show("Passed Variable Are Not Correct", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
 return;
 CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
 CrystalDecisions.Windows.Forms.CrystalReportViewer crv = new CrystalDecisions.Windows.Forms.CrystalReportViewer();
crv.ActiveViewIndex = 0;
crv.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
crv.ToolPanelView = CrystalDecisions.Windows.Forms.ToolPanelViewType.None;
crv.Dock = System.Windows.Forms.DockStyle.Fill;
crv.Location = new System.Drawing.Point(0, 0);
crv.Name = "CrystalReportViewer";
 MySqlDataAdapter at =new MySqlDataAdapter();
 DataSet ds = new DataSet();
 for (int i = 0; i < TableName.Length; i++)
at = GetDataAdeptor(QueryString[i]);
at.Fill(ds, TableName[i]);
 string rptPath = "";
rptPath = Application.StartupPath + "\\" + ReportName;
rpt.Load(rptPath);
rpt.SetDataSource(ds);
 if (Parameter != "")
rpt.SetParameterValue(0, Parameter);
crv.ReportSource = rpt;
crv.Refresh();
 //CrystalReportViewer.DataBind();
 //Me.Panel1.Controls.Add(CrystalReportViewer);
 Panel panel1 = new Panel();
panel1.Controls.Add(crv);

Hi Bhushan,
It's not yet fixed. My dataset (ds) can't bine to DataGridView as
DataGridView1.DataSource = ds
But it could do like this
DataGridView1.DataSource = ds.Tables[0];
When I bine to Crystal Report Viewer setdatasource
CrystalReportViewer1.setdatasource = ds.Tables[0];
It still not work, anyway you suggest let me in the right way. I very confuse the thing I fix to bine to DataGridView
Thank,
Chaiwat

How to print directly to Printer from Crystal Report Viewer ?

Hi All,
We are integrating our Java Web Application with Crystal report XI, currently using JRC and export to PDF for user to preview and print to local printer.
Now there is new requirement :
Some clients is using thin client terminal (no harddisk, only has OS +Browser in ROM), so I cannot install Acrobat Reader for them to preview&print the report.
So I am looking at Crystal Report Viewer, the question is : Can I print from Crystal Report Viewer directly to local printer without first converting it to PDF (because I can't have acrobat reader installed) ??
Thank you very much,
Krist

Hi,
It can't be achieved through XI.
JRCXI R2 SDK offers the ability to print the report server side
using the PrintOutputController using printReport(PrintReportOptions printReportOptions) method.
Here is the code(for XIR2):
import="com.crystaldecisions.reports.sdk.*"
import="com.crystaldecisions.sdk.occa.report.lib.*"
import="com.crystaldecisions.sdk.occa.report.document.*"
try {
final String REPORT_NAME = "Inventory.rpt";
ReportClientDocument reportClientDoc = new ReportClientDocument();
reportClientDoc.open(REPORT_NAME, 0);
//Create and set print options.
PrintReportOptions printOptions = new PrintReportOptions();
//Note: Printer with the 'printer name' below must already be configured.
printOptions.setPrinterName("
10.10.45.220
BOBJ 2C");
printOptions.setJobTitle("Sample Print Job from JRC.");
printOptions.setPrinterDuplex(PrinterDuplex.horizontal);
printOptions.setPaperSource(PaperSource.auto);
printOptions.setPaperSize(PaperSize.paperLetter);
printOptions.setNumberOfCopies(1);
printOptions.setCollated(false);
PrintReportOptions.PageRange printPageRange = new PrintReportOptions.PageRange(1,1);
printOptions.addPrinterPageRange(printPageRange);
//NOTE: If parameters or database login credentials are required, they need to be set before.
//calling the printReport() method of the PrintOutputController.
reportClientDoc.getPrintOutputController().printReport(printOptions);
reportClientDoc.close();
out.println("Successfully sent report to the printer.");
catch(ReportSDKException ex) {
out.println(ex);
Please revert in case you have any query.
Thanks,
Neeraj

Crystal Reports Viewer Control - Visual Studio 2008 WEB Application

My question is this: Has ANYONE on this planet been able to get the ASP .NET CR Viewer control to actually work?
Why does this editor NOT recognize End-of-line or CR characters or any whitespace??
I have developed a Crystal Reports "Viewer" web application in VS2008 using C#.
It's a simple app, in that it's a single page with a treeview control (containing the grouped names of the reports to which the user has access) and the CR Viewer control.
The report files live on a network share, and permissions to them is controlled via a SQL Server database, which, for each report, stores the UserID and Logion for the oracle database, as well as any required parameter values.
The reports themselves are all hititng an Oracle 10g database.
I managed to do this in a Windows desktop applcation using Visual Studio 2005 and VB .net, but now, upon trying to make this a web application in VS2008, I have completely failed. The application works when run locally, but when deployed to the web server, I experience database login prompts when I should not, (the dreaded "Report requires further information" message) even thought the setdatabaselogin has already been set. I have tried saving the reportdocument in viewstate and re-assigning the viewer Datasource property to it, that also fails. However, it only does it on some reports, and not others. (admittedly, the reports may have been created using different CR versions)
The viewer also displays data it should not be displaying when I attempt to scroll, when I do manage to get a report to run.
I am setting parameters dynamically at run time, whose values are stored in the SQL database.
Code Sample:
protected void ShowReport(int ReportID)
 SQLDataPortal2005.Common sql = new SQLDataPortal2005.Common();
 Hashtable outParms = new Hashtable();
 string sAccess;
 IDataReader dr;
 CrystalDecisions.CrystalReports.Engine.ReportDocument rptDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
 System.Security.Principal.WindowsPrincipal p = System.Threading.Thread.CurrentPrincipal as System.Security.Principal.WindowsPrincipal;
 sAccess = p.Identity.Name;
 int j = 0;
 int i = -1;
 if (!IsAdmin())
 sql.ExecNonQuery("CrystalReports", outParms, "proc_CRM_Check_Permissions", sAccess, Convert.ToInt32(TreeView1.SelectedNode.Value));
 if (outParms["@Allow"].ToString() != "True")
 Response.Redirect("ErrorPage.aspx"); // redirect to error page
 string sPath = System.Configuration.ConfigurationManager.AppSettings["WareHouse"].ToString();
 sPath = sPath + TreeView1.SelectedNode.Text.Trim() + ".rpt";
 rptDocument.Load(sPath);
 dr = sql.GetDataReader("CrystalReports", "proc_CRM_Get_Report", Convert.ToInt32(TreeView1.SelectedNode.Value));
 while (dr.Read() == true)
 j += 1;
 if (j < 2)
 rptDocument.SetDatabaseLogon(dr["DB_Login"].ToString(), dr["DB_Pwd"].ToString(), "PLAW", "LAWDB", true);
 pList = dr["ParmList"].ToString().Split(',');
 dr.Close();
 dr.Dispose();
 if (pList.Length > 0 && pList[0].ToString().Trim() != "")
 foreach (CrystalDecisions.Shared.ParameterField x in rptDocument.ParameterFields)
 i++;
 switch (x.ParameterValueType)
 case CrystalDecisions.Shared.ParameterValueKind.BooleanParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToBoolean(pList));
 break;
 case CrystalDecisions.Shared.ParameterValueKind.CurrencyParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToDouble(pList));
 break;
 case CrystalDecisions.Shared.ParameterValueKind.DateParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToDateTime(pList));
 break;
 case CrystalDecisions.Shared.ParameterValueKind.DateTimeParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToDateTime(pList));
 break;
 case CrystalDecisions.Shared.ParameterValueKind.NumberParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToInt32(pList));
 break;
 case CrystalDecisions.Shared.ParameterValueKind.StringParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToString(pList));
 break;
 case CrystalDecisions.Shared.ParameterValueKind.TimeParameter:
 rptDocument.SetParameterValue(x.Name, Convert.ToDateTime(pList));
 break;
 Session["CReport"] = rptDocument;
 CRV1.ReportSource = rptDocument;
 CRV1.DisplayGroupTree = false;
 CRV1.HasRefreshButton = true;
 CRV1.ShowFirstPage();
Is there a better/different way of accomplishing this very simply process? All I need this application to do is to view a report, while setting it's parmeters (if required) dynamically at run time. I don't EVER want the user to be prompted for DB LOGIN INFO.

To answer you question; Yes, I suspect that most of the users in this community have managed to successfully create web apps. And this is the tiniest of sampling of the developers out there...
A few suggestions;
1) Keep the posts to under 1200 characters. Otherwise, the formatting is lost which makes it difficult to read.
2) Try out a few sample apps from here:
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
Suggest; csharp_web_simplelogonengine.zip, csharp_web_simplelogonviewer.zip and csharp_web_subreport_logon.zip.
3) Start simple; one table, one field, no subreports. Hard code the database logon parameters. Convince your self that this does work. Increase the complexity - add fields, tables, subreports. Do not mix connection methods (e.g.; if ODBC for main, than ODBC for sub is a good idea, though not a requirement).
4) See the article [Troubleshooting Guide to Database Connectivity Issues with Crystal Reports in Visual Studio .NET Applications|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b0225775-88c4-2c10-bd80-8298769293de].
5) See [this|http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/d05b3bb7-0f28-2c10-4ea3-84dbdc4e414e?quicklink=index&overridelayout=true] article.

Crystal Reports Viewer 2008 and parameter fields

Hello,
I saw this product on the main Crystal Reports site this afternoon and decided to download it to try it out. I have a number of users who would benefit from being able to preview their report results prior to actually running the report. This seems like the perfect product. I have a large number of Crystal Reports which were created in Crystal version XI. I also downloaded the free 30 day version of Crystal Reports 2008 yesterday to see what new features are there.
While testing Crystal Reports Viewer, I tried to run one of my reports which needs a parameter to run properly (account number). This type of parameter is needed for probably 98% of this business' reports.
The problem: Crystal Reports Viewer does not prompt me to input the parameter. In my actual Crystal Report, I had the box "Save Data with Report' left unchecked, as the account number frequently changes. However, if that box is left unchecked, Crystal Reports Viewer will give me the error message "No Saved Data. This report file does not contain saved data and cannot be viewed. To get data into the report, please open and re-save it in the Crystal Reports designer application with the "Save Data with Report" option selected."
Thinking that possibly it was the version of Crystal Reports in which the report was created (XI), I downloaded the free trial of Crystal 2008 and created a very simple test report with one parameter for account number where the account number is retrieved from our database. And I am having the same trouble.
The "Help" section of Crystal Reports Viewer tells me that I can select my parameters in the parameter panel. I do not see anything in my parameter panel other than the words "Current Data Set Last refreshed: 04/12/10 2:58 PM". The help tells me that I can "select the parameter directly in this panel by entering a new value", but there is no option to do so.
Any help would be appreciated.
thanks,

What I've learned is that I was originally using Crystal Viewer XI and upon opening it I received a message indicating there was an update.
I ran the update which put me on Crystal Viewer 2008.
Since then I have not been able to refresh my screen to bring up the parameters.
See the attached forum for another post concerning this same issue.

Crystal Reports Viewer - pdf, prompts, icons problem

Hi all,
I am a new in BO.
I have some answer about Crystal Reports Viewer (not about setup.exe but about CRV application that I uploaded on Tomcat)
1) The old version (11.5) works good, only Export to PDF functionality is wrong. There are in the pdf file wrong display of specific czech characters (charset)
2) A new version, Crystal Reports Viewer 2008, show the same pdf mistake. I have J2SE Runtime Environment 5.0 Update 4 and Apache Tomcat 5.5.9.
I upload application on Tomcat, configuration (web.xml, crconfig.xml and context.xml) is the same with version 11.5.
Crystal Reports Viewer 2008 displayed reports, but the problem with PDF is present. The second problem is the look of CRV. First one, the icons (for export, print...all icons) are not displayd. I can copy old jar files into java (in application folder C:\WebReports\WEB-INF\lib), but then CRV looks like old version.
And CRV 2008 doesn't display listbox in dynamic prompt on crystal report. What shall I set to displaying prompts in CRV 2008 (on CRV or on report in Crystal 2008)?
Have you some idea? What and how can I set and configure application and where?

Hi,
To confirm, are you talking about "Crystal Reports Viewer 2008" http://www.sap.com/solutions/sapbusinessobjects/sme/reporting/viewer/index.epx
I suggest sending in the report, in the viewer, select "Help" - "General Feedback" and then pick the option to attach the report. In a couple of months there will be a refresh version of this view which will have Czech language support so it would be good if we could test out your PDF issue.
As for showing parameters in the prompt panel in Crystal Reports Viewer 2008, since the viewer cannot refresh the data, make sure the parameter does not used in the record selection formula but only in the saved data selection formula.

Error With Export/Print from Crystal Report Viewer

Hello there,
I've searched through the web and SAP discussion boards with not much luck with this issue.
After working through this for some days now I've decided to look here for help.
Environment:
I have created a web Crystal Report viewer application(Developed with SBOP BI Platform 4.0 SP06 .NET SDK Runtime) that communicates with a managed Cyrstal Server 2011 SP4 (Product 14.0)
I am able to connect and authenticate with the server, retrieve a token for communication and display reports in the Crystal report Viewer successfully.
Problem:
When I attempt to export, I receive the prompt to select format and pages.
When I click export after selections most times I receive an error with the text
Unable to cast COM object of type 'System.__ComObject' to interface type 'CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{74EEBC42-6C5D-11D3-9172-00902741EE7C}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
Other times the page simply refreshes on export.
When I click to print, no print dialog is displayed the page always refreshes and no error is displayed.
No Print or Export document is ever created.
As many print/export issues seems to be related, I'm guessing this two issues are as well.
Notes:
I am utilizing the ReportClientDocument model
I am storing this in session to use as the crystal report viewer report source on postbacks
I am assigning a subset of export formats to the crystal report viewer
I am setting particular parameters as well on the report source
At this point I would appreciate every assistance I may receive on this issue
Thanks in advance,

Thanks Don for your response,
I'm new to the SCN spaces and my content has been moved a couple of times already.
In response to your questions
The runtime is installed on the web application server, if by that you mean the machine hosting the created .NET SDK application.
My question was whether it was also required on the Crystal Server 2011 (I.E. the main enterprise server with CMS and Report management and I guess RAS and all that). I figured this would remain untouched and queries would simply be made against it to retrieve/view reports e.t.c
If install of the SDK on Crystal Server 2011 is indeed required should I expect any interruption to any of the core services after a restart. I.E. I'm hoping that none of the SDK objects would interfere with the existing server objects (in SAP Business Objects)Reason I ask is I note that much of the SDK install directories are similar to the existing Crystal Enterprise Server 2011 (Product 14.0.0)
Is this temp folder to be manually created/configured or is it created by the application automatically to perform tasks. Or are you referring to the default C:\Windows\Temp directory and so saying that the application would try to use this for print and export tasks?Once I'm sure which I'd give the app pool user permission
Printing is to be client side but I figured by default (with the Crystal Report Viewer) it would simply pool and print from the user's printer. This is how it works with the previously used URL reporting approach (viewrpt.cwr). Therefore a user can print the document from wherever they are with their own printer.We don't intend on printing from the server machine, but are you suggesting that a printer must be installed on server (which one web or enterprise server) for any client side printing to work.
App pool is running in 32 bit mode
Initially didn't get anything useful from fiddler but I'd try and look closer on your suggestion.
It's also possible that some of my questions are a misunderstanding of APP vs RAS vs WEB, so please feel free to clarify. Currently I see the Web server as simply the created .NET SDK Application and RAS (Crystal Server 2011 e.t.c) as the existing fully established Application server which I simply pool for information.
Thank you for your patience and advice,

Crystal report viewer from portlet

Hi,
I have a problem with opening Crystal report viewer from portlet. I am using Spring portletMVC but this doesnt matter in this case. After clicking some button a controller process form in method where is access to ActionRequest, ActionResponse. But how can I "redirect" with some parameters to plain JSP page where I can write something like this:
CrystalReportViewer viewer = new CrystalReportViewer();
     viewer.setReportSource(rcd.getReportSource());
     viewer.processHttpRequest(request, response, getServletConfig().getServletContext(), out);
     viewer.dispose();
Oh, perharps is understandable, sorry for my English and thanks for helping. Any code of link would be wonderful.

I haven't worked with Crystal Reports in quite awhile, but in the past I've written code to launch Crystal Reports using OLE. If I recall correctly, there existed an ActiveX control that could be embedded into VB forms, and the like. I'm unsure, however, whether they continue to support this mechanism. Given that your requirements do not allow CLIENT_HOST or DDE, however, I am guessing that OLE automation would also be unacceptable.
Have you looked at WEB.SHOW_DOCUMENT?

BO XI R2 - "Blank "Crystal Reports Viewer" window - attempt to print report

My company recently set up a Business Object Enterprise XI Release 2 server. On the server are a number of crystal reports that are run interactively by users, through the user console. The expectation is that the user will log on to the BI server, click on the report title, enter the parameters, see a preview of the report in the Crystal Report Viewer, then click the print icon on the Crystal Report Viewer toolbar.
Our corporate standard is current Windows XP SP3, with Internet Explorer 8; By default, users are set up to use the DHTML report viewer. The reports were developed with the Crystal Reports XI R2 report designer, and connect to an Oracle 10g database through Oracle client.
When users attempt to view, then print the reports, the user is able to select the report, enter the parameters, view the report data, and even page through the report preview with no issues. However, when the user attempts to print the report by clicking the print icon on the Crystal Reports Viewer toolbar, a blank "Crystal Reports Viewer" window pops up and remains indefinitely.
The really puzzling thing about this issue is that for about 1/3 of our users, printing will work - a print dialog will appear, allowing the user to select a printer, and when the user clicks OK, the report will print. For the other 2/3 of our users, the blank "Crystal Reports Viewer" window pops up.
I have added the BO XI R2 server's address to trusted sites, adopted the lowest security settings for trusted sites, and enabled all activity I could think of in IE security settings (ActiveX controls-related). I also ran the web site in compatibilitiy mode.
Has anyone on this forum experienced this issue, and does anyone here know how to resolve it?
Thank you,
Bob Gardner

I suspect that this behavior occurs because the client computer is unable to download ActiveX controls.
The report viewer requires the PrintControl.dll to print reports from the client computer. The PrintControl.dll downloads automatically if it has not been previously downloaded on to the client computer, provided that the user that is currently logged on is able to download ActiveX controls.
To enable the download of ActiveX controls on the client computer, perform the following steps:
1) Open your Internet Explorer.
2) From the Tools menu, select Internet Options.
3) In the Security tab, select the web content zone that corresponds to your web application.
4) Click Custom Level.
5) In the Security Settings dialog box, scroll down to find the ActiveX controls and plug-ins section.
6) Select Enable or Prompt for the Download signed ActiveX controls item.
7) The print dialog box will now appear successfully when clicking the print button in the report viewer.
If the above does not help, try to troubleshoot this as follows:
1) click the print button (this will cause a postback to the web page) and then cancel the print dialog. right-click in the web page and select "View Source".
2) Search for the word "printcontrol.cab". This will show you where the application is trying to download the printcontrol from.
Paste the URL into a browser.
3) If you get prompted to "open or save to disk" the url is correct and there is a browser setting or possibly even a system policy preventing the download.
4) If you get a "404 page not found" or a similar error message, investigate the URL.
5) If the issue is on your local web server, see if it is possible to browse to the URL in IIS manager.

Dynamic command execution fails in Crystal report viewer

We are using the Crystal Report Viewer for the .Net Application on the client side.The reports are designed using Crystal Report XI R2.
The issues that i am currently encountering is that, we are unable to load the combo-boxes in the pop-up for the parameters.
All the reports have multiple commands and the variables are of 'dynamic' type.
When the dialog box for requesting the pop-up comes up, It comes up empty even though they are linked to the respective commands.
Also,For reports having multiple parameters we are unable to give a single dialog box to get in all the parameters.It appears as a series of prompts.
Both,these issues are not encountered when the reports are launched via the Crystal reports developer tool.

Did you end up cross posting this anywhere else? I just started running into the problem with XI r1 trying to view a report I modified in r2. The only solution I seem to have found involves upgrading all of our customers to r2, which is not a very pleasant option. I'd be interested in learning if anyone has come up with a better solution.
