ReportDocument.SetDataSource(DataTable dataTable) OutOfMemoryException

When a customer attempts to display a certain report with a calendar year of data, they get the OutOfMemoryException. Apparently they can successfully display any other report before or after. This is .NET 2.0, Crystal Reports 2008 on a desktop client querying a database server.
Exception: Exception of type 'System.OutOfMemoryException' was thrown. (Type: System.OutOfMemoryException; Source: System.Data)

Can any configuration be set to provide more memory? Is there a way to tell in advance if a dataset or datatable is too large?

Doh... Sorry should have noticed that you are using a DS
Yes, in CR 9 it was lighter, after CR 10 they rewrote/updated the DB drivers as well as other new features so CR consumes more memory space.
DS's are good for about 5K rows, depends on the amount of data in the row of course, anything more and you will always get an out of memory error. Due to limitations in the way Windows handles DS's, now one can access the DS directly so when you use it CR needs to copy the DS it our memory space thus doubling the amount of memory required.
If you are going to allow them to use large data sets then either create another report that hits the DB directly or convert the existing report using RAS using the Replace_Connection method ( search here for sample code ) and set location to the DB using OLE dB Provider.

Error on reportdocument.SetDataSource

Hello. I am working in VS 2010 environment. I am trying to open a report based off of data set. But looks like I am doing something wrong, it's throwing an exception with 'Invalid report file path'. Can you tell me what I need to do load from a dataset correctly? I am crystal reports for VS2010. Thanks.
Here's my code:
    Private Sub loadCrystalReport() Handles CrystalReportViewer1.Load
        Dim dsData As New Data.DataSet
        Dim sqlcmm As SqlClient.SqlCommand
        Dim daAdapter As New SqlClient.SqlDataAdapter
        Dim cnn As New SqlClient.SqlConnection
        cnn.ConnectionString = " server=bbsql5;" & _
            "uid=masif;password=testpass;database=casemang"
        cnn.Open()
        If cnn.State = ConnectionState.Open Then
            sqlcmm = New SqlClient.SqlCommand("select * from dailylog", cnn)
            daAdapter.SelectCommand = sqlcmm
            daAdapter.Fill(dsData, "DailyLog")
            If dsData.Tables(0).Rows.Count > 0 Then
                reptDoc.SetDataSource(dsData)
                CrystalReportViewer1.ReportSource = reptDoc
            End If
        End If
    End Sub

Not sure why it's not giving me the results from the select query instead of the whole report then. Here's my code.
reptDoc is the the document. I am trying to load the report DailyLog.rpt with the data set from my query . But right now it loads everything.
    Private Sub loadCrystalReport() Handles CrystalReportViewer1.Load
        Dim dsData As New Data.DataSet
        Dim sqlcmm As SqlClient.SqlCommand
        Dim daAdapter As New SqlClient.SqlDataAdapter

        cnn.ConnectionString = " server=bbsql5;" & _
            "uid=masif;password=testpass;database=casemang"
        cnn.Open()
        If cnn.State = ConnectionState.Open Then
            sqlcmm = New SqlClient.SqlCommand("select * from dailylog where rundate >='8/18/2011'", cnn)
            daAdapter.SelectCommand = sqlcmm
            daAdapter.Fill(dsData)

CrystalDecisions.CrystalReports.Engine.InternalException Error

CA Forum: .NET
I am getting the following error when generating and printing a crystal report from my .net project. It's rather intermitant, that is i know the data isn't the problem as have re-run a record which caused the error and it printed successfully. Little bit confused as to actually what is causing the problem? One thing i did try is moving to a different printer which helped, that is the problem happens less frequently but still occurs. Any ideas Ta CrystalDecisions.CrystalReports.Engine.InternalException: Error in File F:\DOCUME1\ADMINI1.RIM\LOCALS1\Temp\Omgeo Import Print {7AE4245E-AC71-47F2-BEDB-C76014B48B83}.rpt:The request could not be submitted for background processing. ---> System.Runtime.InteropServices.COMException (0x800002AD): Error in File F:\DOCUME1\ADMINI1.RIM\LOCALS1\Temp\Omgeo Import Print {7AE4245E-AC71-47F2-BEDB-C76014B48B83}.rpt:The request could not be submitted for background processing. at CrystalDecisions.ReportAppServer.Controllers.DatabaseControllerClass.ReplaceConnection(Object oldConnection, Object newConnection, Object parameterFields, Object crDBOptionUseDefault) at CrystalDecisions.CrystalReports.Engine.Table.SetDataSource(Object val, Type type) at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type) --- End of inner exception stack trace --- at CrystalDecisions.ReportAppServer.ConvertDotNetToErom.ThrowDotNetException(Exception e) at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type) at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSource(DataTable dataTable) at OmgeoImporter.CrystalComponent.setDataSetTable(DataTable dsp) at OmgeoImporter.Importer.printCrystal(DataSet txtds)

Intermittent issues can be very difficult to troubleshoot and solve. This particular error typically occurs when trying to process data (not necessarily a particular row of data), but it could be related to other things (as you noticed when changing printer drivers). I would make sure you have the latest patch for the version of CR you are using as there have been fixes done for this error.
Otherwise, I recommend working with the BOBJ support team to help troubleshoot the issue as there are a lot of things that can be investigated to find the root of the issue.

AccessViolationException after upgrade to 2008

I have just now upgraded from the crystal reports basic version that comes with visual studio 2008 to the full Crystal Reports 2008. On opening a project it came up with the upgrade adviser thing and I ran it through seemed to work and compiled properly on running the reports unfortunately I am getting an AccessViolationException.

                CrystalViewer.DataBind();
The above is a snippet of the code this is a push report so it first fills a student registers data table. The error comes up on th eline underneath CrystalRepSource.ReportDocument.SetDataSource((DataTable) studentDataTabel).
I thought it might be push reports so I tried another this failed on trying to set logon info:
TableLogOnInfo logOnInfo = new TableLogOnInfo();
logOnInfo = CrystalRepSource.ReportDocument.Database.Tables[0].LogOnInfo;
Any ideas what the problem is as the error is a bit generic suggests possible memory corruption but that is definately not it. The reports were definately working pre upgrade and I do have a backup but would like to resolve this ASAP as I want to use some of the powerful new features.
p.s. this has service pack 0 installed

Report.SetDataSource throws exception upgrading from VS2005 to Xtal 2008 VA


Using Visual Studio 2005 with Crystal 2008 Visual Advantage on Vista w/ SP1. Visual Studio has all service packs applied as well.

I am trying to evaluate the Crystal 2008 Visual Advantage product.

Here's the use case: I get an IEnumerable of a certain object at run time, then pass this list of objects to SetDataSource(IEnumerable). This code ran fine under the version of crystal included with VS2005, but after installing the product and running the Crystal 2008 VA conversion wizard on this project, SetDataSource now crashes and burns with the following:

System.Reflection.TargetParameterCountException {"Parameter Count Mismatch"}

The exception is clearly in the Crystal runtime, as the stack trace reveals (see below). I should also mention that the database verifies, and that I have been able to relocate the database with the databse locator. No luck. Clean and rebuild, No luck. Anybody got any suggestions?

I have compiled and run these tutorials with no problems.
 
I must reiterate that I don't see how these tutorials could possibly be pertinent to the problem.
 
I can set my object collection to be a datasource for other .NET data aware controls such as datagrids and so forth, and to Crystal Reports .rpts compiled with the VS2005 and VS2008 supplied product. I cannot set my object collection to be a datasource for the stand-alone VA product.
 
Your XII runtime is crashing with an "invalid number of parameters" exception. This is a serious programming error, and it cannot be caused by my code -- my code cannot tell your runtime how many parms to call a .NET method with.

SetDataSource causes code reentrance (bug)

Post Author: willi
CA Forum: .NET
Using CR.Net 1.1 SP2 (VS 2003 SP1), WinXP Prof/SP2Problem:Calling the SetDataSource method of a ReportDocument object causes code reentrance, probably due to processing the message queue. This can cause unexpected problems. The callstack in the following example shows that a Timer's Tick event occurs while calling the SetDataSource method:CSSReports.Form1.Timer1_TickSystem.Windows.Forms.Timer.OnTick System.Windows.Forms.Timer.DebuggableCallback CrystalDecisions.CrystalReports.Engine.ReportDocument.Load CrystalDecisions.CrystalReports.Engine.ReportClass.Load CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSource This must not happen! Other events could occur, too. Is there a hotfix for this problem? This is a serious issue because while loading one report I was able to select a MenuItem and open a 2nd report before loading the 1st report finished (not a multithreaded application). This behavior can just as many problems as explicitly calling Application.Doevents. In short: SetDataSource must not process any messages in the mesage queue.

It looks like the error only occurred when I used JUnit to test it - which was probably due to something I did. When I managed to get the code working, the problem was that the newly added table got referenced by the next itteration. I solved it by using a HashMap.
Map<String, ResultSet> results = new HashMap<String, ResultSet>();
Tables tables = reportClientDoc.getDatabaseController().getDatabase().getTables();
for (int i = 0; i < tables.size(); i++) {
 String tableAlias = reportClientDoc.getDatabaseController().getDatabase().getTables().getTable(i).getAlias();
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
 Connection con = DriverManager.getConnection("jdbc:odbc:CSV_DSN");
 Statement stmt = con.createStatement();
 String query = "select * from " + tables.getTable(i).getName();
 ResultSet rs = stmt.executeQuery(query);
 results.put(tableAlias, rs);
final Enumeration<String> aliasEnumeration = Collections.enumeration(results.keySet());
while (aliasEnumeration.hasMoreElements()) {
 String oldAlias = aliasEnumeration.nextElement();
 ResultSet rs = results.get(oldAlias);
 reportClientDoc.getDatabaseController().setDataSource(rs, oldAlias, oldAlias + "_rs");

Problem with SetDataSource and SubReports

Post Author: soxi
CA Forum: Data Connectivity and SQL
Hello,
I have an application wich displays report with a dropdowlist.When I display a report with subreports, this works once but after I have an error.
I fill a dataset with several table.One table for the main report et two for the two subreports.
da = new OracleDataAdapter("request1", cn);da.Fill(ds, "tableMain");da.SelectCommand.CommandText = "request2";da.Fill(ds, "tableSubReport1");da.SelectCommand.CommandText = "request3";da.Fill(ds, "tableSubReport2");cn.Close();
After I bound my dataset with my report et subreports:
1 for (int i = 0; i < ds.Tables.Count; i++)2 {3 if (i == 0)4 this.CRSource.ReportDocument.SetDataSource(ds.Tables[i]);5 else 6 {7 this.CRSource.ReportDocument.Subreports[i - 1].SetDataSource (ds.Tables[i]);8 }this.CRSource.EnableCaching = true;this.CRViewer.ReportSource = this.CRSource;
Error Message:My error message throws at the line 7:"System.Runtime.InteropServices.COMException: Le canal de communication n'a pas été créé.",(It is a french error, In english I think it was:"The channel of communication has not been established").
When I enclose this line 7 with a "try" and a "catch" empty, a page come back:This page asks me this information:Server name,Database name, user name and password.
Ask:I don't understand this error.I have search in all forums.Have you an idea of this problem?

Thanks i got the audio problem fixed.
When I open up final cut it says some of the media has been disconnected but it then says I can't reconnect it or something like that, I don't know if that effects the transitions. I split up a lot of footage and rearranged it and for one of the places where it flashes a clip it shows one of the pieces of footage that I had deleted because it had a glitch and the other places I noticed it it had random clips from throughout the project, like a flash of an interview that happens way later in the film. So it is random clips that are in the film and even clips that I deleted.

SubreportClientDocument.DatabaseController.SetDataSource problem

This is a Windows application that uses RAS.
Here is a code snippet:
Dim rasDataset As ISCRDataSet
rasDataset = DataSetConverter.Convert(dsProject)
boSubreportClientDocument.DatabaseController.SetDataSource(rasDataset)
When I try to set the datasource, I get "The document has no tables"
All the data tables required for the report to run are in the dsProject.
Why do subreports need their dataset converted? The main reportdocument.SetDatasource takes a normal .net system.data.dataset ...but the SetDataSource on subreports need to be type ISCRDataSet ...is this true?
The report being used as a subreport references tables. If I run the report as a standalone report, it works fine.
Thanks,
Jeff

Hello Jeff,
the code below does not use RAS but demonstrates how to pass Datasets to main and subreports in VB.NET.
Please see if it is of any use for you.

How to refresh a crystal report automatically ?

I deployed my website(asp.net/c#) in IIS 7.5, when i click on the button to open the page that contain the report, i get a blank page but when i refresh the page (F5) it's ok. my question is: how can i open the page that contain the report file directly
without refresh?

Tricky to guess without seeing any code.
Here's some example code which fills and shows a report.
protected void Page_Load(object sender, EventArgs e)
ReportDocument rd;
DataTable dt = (DataTable)Session["xxxxx"];
// Tricky bit here is to make the name of the datatable match what the report expects
dt.TableName = "DataTable1";
rd = new ReportDocument();
rd.Load(Server.MapPath("Reports\\xxxxReport.rpt"));
rd.SetDataSource(dt);
rd.Refresh();
CrystalReportViewer1.ReportSource = rd;
CrystalReportViewer1.RefreshReport();
CrystalReportViewer1.DisplayGroupTree = false;

Report Document.Load Method Hangs

The following code is an exceprt from an asp.net web application we developed. The report file (TestReport.rpt) file was designed using a 'manually' created schema (xsd) that mirrors the structure of pApptDT. The .xsd file has no DB connection info stored in it. NOTE: the DBServiceORA and Registrations are base and middle tier classes respectively that do the heavy lifting.
protected void Page_Load(object sender, EventArgs e)
 mDBService = (DBServiceORA)Session["DBService"];
 this.BuildReport();
protected void BuildReport()
 ReportDocument pReport = new ReportDocument();
 try
 DataTable pApptDT = Registrations.GetApptSmry (mDBService);
 string pReportFile = Server.MapPath(Global.WEB_ROOT + @"/Reports_Appointment/TestReport.rpt");
 pReport.Load(pReportFile);
 pReport.SetDataSource(pApptDT);
 MemoryStream pStream = (MemoryStream)pReport.ExportToStream(ExportFormatType.PortableDocFormat);
 HttpContext.Current.Response.Clear();
 HttpContext.Current.Response.ContentType = "application/pdf";
 HttpContext.Current.Response.AddHeader("Content-Disposition", "inline; filename=Report.pdf");

In our development environment we use IIS (not the built-in web server) which uses Windows integrated security. My company recently pushed down new global policies to all desktops. These new ploicies affected Local Security Policies and permissions on some files in the \windows\system32 directory. When stepping through the code with the debugger, the application now hangs on the pReport.Load method.
I need help in understanding the internals of the CR ReportDocument.Load method. We think the problem is somehow associated with CR trying to connect to a non-existent DB using some protocol that got affected by the policy changes. Can anyone shed some light on our problem, in particular what's happening inside the Load method.
Thanks
Dan

Tried several options.
OPTION 1:
Created new VS2008 "Crystal Reports Application".
'Manually' created schema (Activity.xsd) containing no DB connection information.
Created Activity.rpt (that referenced the above Activity.xsd file).
Created our 'normal' aspx page with code as follows:.
DataTable pActivityDT = mDBService.GetDataTable("select * from E_ACT;");
string pReportFile = Server.MapPath(@"/CRTestApp1/Activity.rpt");
pReport.Load(pReportFile);
pReport.SetDataSource(pActivityDT);
MemoryStream pStream = (MemoryStream)pReport.ExportToStream(ExportFormatType.PortableDocFormat);
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "application/pdf";
HttpContext.Current.Response.AddHeader("Content-Disposition", "inline; filename=Report.pdf");
HttpContext.Current.Response.BinaryWrite(pStream.ToArray());
First attempt at displaying the above page results in making it past the pReport.Load but hung on the pReport.SetDataSource. All subsequent attempts hung on the pReport.Load method. (?????)
OPTION 2:
Usng the VS-generated Default page (which included the CR Viewer) the ReportSource was set declaratively as follows:
<form id="form1" runat="server">
 <div>
 <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="True"
 Height="1039px" ReportSourceID="CrystalReportSource1" Width="901px" />
 <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
 <Report FileName="Activity.rpt">
 </Report>
 </CR:CrystalReportSource>
 </div>
</form>
Attempting to display the above page results in the application hanging. I also tried setting the source to a non-existant file just to see if an exception would be thrown. I got the expected 'Load report Failed' message followed by parital rendering of the CR viewer.
OPTION 3:
The report displays as expected when a new connection (pproviding the DB login credentials) is created in the CR Database Expert dialog screens and the Activity (E_ACT) table is selected and used as the datasource for the report. With this option, the designer displays data from the Activity table in the Main Report Preview screen. When running the application the CR Viewer prompts for DB login credentails.
Hope this sheds some light on the issue we're having.

How to create an editable previewable report?

The Situation (the report is CrystalReports.Engine.ReportDocument):
I load the report (.Load(Template)) and set data (.SetDataSource(DataTable)). I save the report (.SaveAs or .Export). The Template does not necessary contains fields in DataTable used as datasource.
When I open the created report in "Crystal Reports 2011" the report preview is shown. When I switch to the design tab I can drag fields to the report, but when I switch to the preview again a dialog asking for ado.net xml datafile is shown and when canceled (I have no datafile) empty preview is shown. In Visual Studio 2010 (CRVS 2010?) I see the preview when I cancel the dialog and click the design and the preview again.
The Question:
Is it possible to create a report containing data with the preview working after report is edited?
Note:
I can achieve the desired behavior with external data file, but this soulution is not very convenient.

Ah... that helps a lot...
A couple of ways to go about this. From your template report compare the fields that exist in the report with those your Query has and add them into the Report. You can use the Command Object to append the fields and then the report will need to be refreshed against the XML file. In this case though the report will need to be ran again.
Another option is to export your data from your Query into a DataSet and simply .setlocation to the DS, great for small amounts of data, less than 2K rows or so but you'll have to test for the limits.
Another option is to to use RAS to completely create the report from nothing. See these samples on how to:
http://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsSDKSampleApplications
Bottom line is if you change the fields in a report it is going to have to be refreshed so the report can add/update the field reference list saved in the RPT file. If they don't match CR will simply delete all fields it can't match up.
If using RAS to Create the report and set it to the new field list then you can build your own "Report Designer"
As for running the Query again, that depends on how and where the data exists. If you save your date results into an XML file then it won't hit the DB again.
This will generate the XML file:
ds.WriteXml(@"D:\Atest\list_of_workflows.xml");
ds.WriteXmlSchema(@"D:\Atest\list_of_workflows.xsd");
Then load the XML file into a Dataset and then simply use:
rpt.SetDataSource(ds);
To set the Report to the XML file.
XML is the preferred way and it doesn't have any memory limitations as Active DataSets do. ( MS limitation due to security, CR can't access the original so we have to make a copy which effectively doubles the amount of memory required )

Crystal Reports prompt issue on export: "The report you requested requires further information"

I have searched through forums for a solution but none seem to work for me.
I have an ASP Webform/MySql application which displays Crystal Reports.
The ones which do not require a user to enter a parameter display fine and I am able to click on export on the CR toolbar and download, e.g. .pdf format.
On the report that require a user to enter a parameter, the report renders fine but when I click on the export button, i get the prompt:
"The report you requested requires further information"
asking for DB login credentials. How can I avoid this?
My Code:
Aspx page:
<%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" Namespace="CrystalDecisions.Web" TagPrefix="CR" %>
<div>
 <CR:CrystalReportViewer Width="960px" ID="CrystalReportViewer1" runat="server" AutoDataBind="true" />
</div>
protected void Page_Load(object sender, EventArgs e)
 if (Request.QueryString["report"] != null)
 string reportToGet = Convert.ToString(Request.QueryString["report"]);
 switch (reportToGet)
 case "payslip":
 PaySlip();
 break;
 case "pastpayslip":
 PanelPastPaySlip.Visible = true;
 break;
 default:
 break;
protected void btnSearch_Click(object sender, EventArgs e)
 if (txtDate.Text != null || txtDate.Text != string.Empty)
 if (DateTime.TryParseExact(txtDate.Text, "yyyy-MM-dd", CultureInfo.InvariantCulture,
 DateTimeStyles.None, out date))
 PastPaySlip();
private void PastPaySlip()
 // Some code....
 PayMasterDataSetTableAdapters.pastpayslipcasualviewTableAdapter ta =
 new PayMasterDataSetTableAdapters.pastpayslipcasualviewTableAdapter();
 PayMasterDataSet.pastpayslipcasualviewDataTable dt = new PayMasterDataSet.pastpayslipcasualviewDataTable();
 ta.FillBy(dt, userId, businessId);
 cReport = new ReportDocument();
 string reportPath = Server.MapPath("~/Views/CasualLabour/Reports/PastPaySlip.rpt");
 cReport.Load(reportPath);
 cReport.SetDataSource((DataTable)dt);
 cReport.SetParameterValue("Date", date);
 cReport.SetDatabaseLogon("userID", "password", "server", "database");
 CrystalReportViewer1.ReportSource = cReport;
 CrystalReportViewer1.ReuseParameterValuesOnRefresh = true;
I am using CR V. 13.0.9 and VS 2013 Update 2

This is because almost any action on the viewer result sin a postback. This includes paging, zooming, drilling exporting and printing. E.g.; you will have to place the report in session. See the following KB for how to:

Crystal report in wpf

hi i am new in WPF.
How to i can use crystal report in WPF?
is their any help..?

The documents tend to tell you to use odbc, this is a bad idea.
Don't just read the data in the report.
You want to get your data yourself and supply it to the report.
Build your report against a fixed table or stored procedure but don't use that directly when live.
If you have a datatable then that's probably the easiest option.
You want a source of data to design your report against and the simplest is a stored procedure or a table.
You can create a table temporarily for this, or even use xml but you need something concrete to design against.
A stored procedure should have only one output - use
Set Nocount on
Or you'll have two.
Build your report against that table or stored procedure ( the option to "see" stored procedures is a bit fiddly to find ).
You won't use that live though.
Print preview will involve the viewer, so you're going to put a crystal report viewer on a window or whatever.
And here's some code should give you an idea.
This is out an old asp.net application - you will obviously not be using server mappath to find your report file.
protected void Page_Load(object sender, EventArgs e)
ReportDocument rd;
DataTable dt = (DataTable)Session["xxxData"];
// Tricky bit here is to make the name of the datatable match what the report expects
dt.TableName = "DataTable1";
rd = new ReportDocument();
rd.Load(Server.MapPath("Reports\\xxxReport.rpt"));
rd.SetDataSource(dt);
rd.Refresh();
CrystalReportViewer1.ReportSource = rd;
CrystalReportViewer1.RefreshReport();
CrystalReportViewer1.DisplayGroupTree = false;
I adapted someone's code for them to answer another question which ended up:
DataTable dt = new DataTable();
string connString = "data source=192.168.1.5; initial catalog=hrdata;uid=sa; password=1234";
using (SqlConnection con = new SqlConnection(connString))
con.Open();
SqlCommand cmd = new SqlCommand("ViewEmployeeNoR", con);
cmd.CommandType = CommandType.StoredProcedure; ..........
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(dt);
ReportDocument objRpt = new Reports.CrystalReportData1();
objRpt.SetDataSource(dt);
crystalReportViewer1.ReportSource = objRpt;
crystalReportViewer1.Refresh();

JRC & C++ ???

Hi
I've just downloaded crystal reports for visual studio 2010, i created a report linked to an xml file which i generated by the .NET dataset.writexmlschema method.
I tried to do this:
CrystalDecisions.CrystalReports.Engine.ReportDocument rptDoc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
rptDoc.Load("demo.rpt");
rptDoc.SetDataSource((DataTable)tablaS);
crystalReportViewer1.ReportSource = rptDoc;
But it throws an exception at Load()
it's in spanish but it refers to something like (in innerexception) "a document processed by JRC engine cannot be open in C++ stack" ( Un documento procesado por el motor JRC no se puede abrir en la pila C++.)
what might be happening?
thanks in advance

Hi Ludek
I have the same problem.
I use the full path to the report but still no luck.
I have tried to use different methods.
Nr 1: Open method
=====================
Dim crGeneratedReport As New ReportClientDocument()
crGeneratedReport.ReportAppServer = String.Format(":", rasURL, RASPort)
crGeneratedReport.ReportAppSession.Initialize()
crGeneratedReport.Open(CType(filePath, Object), 1) --crash here
Nr 2: Load method
===================
Dim rptDoc as CrystalDecisions.CrystalReports.Engine.ReportDocument rptDoc = new CrystalDecisions.CrystalReports.Engine.ReportDocument()
rptDoc.Load(m_ReportFilename, m_ReportServer) --crash here
crystalReportViewer1.ReportSource = rptDoc
I have also tried changing the path and I can even open the folder on the remote server from my pc in explorer(start/run box, path) by using the same string as I send, but no luck.
The report file that I want is on the report server, and this worked well in CR2008, but now it seems something has changed.
What can be the problem?
Is there a service pack that can help?
regards Uffe
