How to avoid database logon dialog on every action of refreshing reports

I am using Crystal reports 208 SP2 and has a database connection to oracle database. Connection is esablished and report retrieves desired data, The problem is when ever i open this report ( which has this connection set) and do a refresh, the report the LogOn dialog pops up.
How to avoid or save this log on info such that it does not pops up the LogOn dialog when i open the report and do a refresh(F5).?

Hi Don,
Thanks for the reply. To try your suggested approach, i need some clarifications .
_Problem summary:for refrence, _
I am following the steps mentioned below to establish a database connection, and fetch the data.
1) I am using Oracle drivers for configuring the ODBC data source. As part of configuration i will specify the Oracle server name
2) In crystal reports, Using "Database" menu, i open "Database Expert" dialog and "Make New connection" by specifing the data source mentioned in step 1). During this process, (ODBC)logon information will be filled in. The user ID and password used has all the rights to access the tables in the database. Logon will be successful and connection is established.
3) Further i use the database table from the "Database Expert" on to the report and refresh(F5) to fetch the data.
After step 3, I close the report and reopen it. Now trying to refresh the database logon dialog pops up. I need to avoid this pop up
Requesting Clarification:;
1) You have specified "When you connect you have the option to use Trusted Authentication, check this option on". Where is this option. Is it in the crystal reports or is it available during data source configuration. Kindly specify.
2) Here "Enterprise logon info that has been configured on the Oracle server." implies the oracle database login information right? If yes, this login details are available and i am using this logon information(i.e. UseriD and Password) during database connection.
If No, Is "Enterprise logon info " is something which should be specifically enabled by DBA in oracle11g configuraion.
Kindly suggest.

How to use native XML driver in CR XI 2 (to avoid "Database Logon Failed")?

Hello,
I have a simple scenario:
The Java Part:
-Our Java application creates a pair of files: one XML and one XSD.
-Both files are uploaded to an ASP.NET page along with a report (RPT file - based on the same XSD and some generated XML using the native XML driver) for rendering a PDF.
The ASP.NET(VB) Part:
-Reads and stores 3 files (XML, XSD and RPT) to temporary files.
-Loads the report
-Updates connection attributes ("Local Schema File" and "Local XML File") to point to those temporary files.
-Exports the report to a PDF which is returned to the Java part.
What are the correct steps to accomplish this? I keep on getting "Database logon failed." exceptions.
My code looks like this:
Dim doc As ReportDocument = New ReportDocument
doc.Load(rptPath)
Dim attr As DbConnectionAttributes
attr = New DbConnectionAttributes()
attr.Collection.Set("Local Schema File", xsdPath)
attr.Collection.Set("Local XML File", xmlPath)
Dim conn As IConnectionInfo
conn = doc.DataSourceConnections.Item(0)
conn.Attributes.Collection.LookupNameValuePair("QE_LogonProperties").Value = attr
conn.Attributes.Collection.LookupNameValuePair("QE_ServerDescription").Value = xmlPath & " " & xsdPath
conn.Attributes.Collection.LookupNameValuePair("QE_SQLDB").Value = False
doc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, False, "")
Thank you for any help,

Hi,
When you get a database logon prompt like this it normally means the dataset you're creating at runtime does not match the schema that the report was designed with.
The simplest thing to do is write out the dataset to XML with Schema after you fill the dataset. Once you've written out the dataset you can go back to the report in Crystal Reports itself and try to point the report to the XML file directly. If you get any errors this confirms that the dataset does not match what the report is expecting.
Try it, address any differences, and you should be all set.
Sincerely,
Amit

How to pass database logon info to a Crystal Report in a subreport with different server name using VS C #

Post Author: fabu1971
CA Forum: .NET
I could pass the database logon in Reports with subreports but the reports with subreports with different server name I can not pass the logon information . Do you have any idea how I can do that to pass the database logon with different database or server name ?

You can use the Subreports collection of the ReportDocument object to access all the subreports in your main report. These are returned as ReportDocument objects. Once you have your subreport as a ReportDocument you can loop through your Tables collection and set the ConnectionProperties to your appropriate Server/Database. For example here is some pseudo code: ConnectionInfo boConnectionInfo = new ConnectionInfo();boConnectionInfo.ServerName = "serverName";boConnectionInfo.DatabaseName = "databaseName";boConnectionInfo.UserID = "username";boConnectionInfo.Password = "yourpassword"; foreach(ReportDocument boSubreport in mainReport.Subreports){ foreach(Table boTable in boSubreport.Database.Tables) { TableLogOnInfo boTableLogOnInfo = boTable.LogOnInfo; boTableLogOnInfo.ConnectionInfo = boConnectionInfo; boTable.ApplyLogOnInfo(boTableLogOnInfo); boTable.Location = "newtablelocation"; }}

How to hide Database Logon option when scheduling Crystal Report in BOE?

Hi All,
For security reason, we are try to hide the Database Logon option in Crystal Report Schedule page in InfoView.
There is option in CMC which we can configure the default Database logon option so that users do not have to enter the logon everytime they view or schedule the report. However, we are looking to hide this option completely.
Does anyone know if there is a security setting which can hide the option from specific users?
Thanks,
Bobby

Hi Bobby,
As Jorge informed that there is no method available within CMC to hide database logon option when scheduling or viewing a Crystal Report in the Info view. This is very much true.
But as you also mentioned that you don't want your users to enter the database logon credentials evertime they view or schedule a crystal report, there is one setting in CMC which we can do to avoid prompt for database logon credentials.
CMC - Home - Go to that specific crystal report - Click Process tab - Click the sub-tab 'Database' and at the bottom of the page there is an option "Use same database logon as when report is run". Check this option after providing the database credentials and click UPDATE.
Now whenever users try to view or schedule this specifc crystal report they won't be prompted for the database logon credentials.

Venkat

How to avoid "font substitution" dialog?

When I try to manipulate the contents of a text layer via scripting and I don't have the needed font installed, Photoshop opens a dialog asking me:

Thanks in advance.

Thanks for looking into this!
PRN is same as Postscript file. We are generating Doc to PRN format then using Adobe Distiller for converting it to PDF file. How can we stop the substitution of the fonts? Also in earlier mail, I have attached the font details of the Adobe Distiller setting.
Can you please advise us is there any other option/setting? Our requirement is to do without substitute the font from DOC to PDF file.

How to set Database Logon Info, if allowDatabaseLogonPrompting="false"

Hey,
Here is the Version Details -
Crystal report X1 R1
Sql Server 2005
Tomcat 5.5.27
Question -
I am using jsf viewer to dispaly report in my web project. We don't want to prompt for database logon information before showing the report to teh front user. I have seen few sample jsp code which creates the crystalreportviewer object and set the connectioninfo details and calls the processhttprequest method to render the report. I have tried the same approach and it works for us.
But our requirement is to just use the jsf tags. Is there a way to pass the database credentials to the jsp without prompting for Logon Information or using the java code to populate the connectioninfo in crystalreportviewer instance.
Here is the jsp file -
<%@ taglib uri="/crystal-tags-reportviewer.tld" prefix="crviewer" %>
<crviewer:viewer displayGroupTree="false" viewerName="CrystalViewer"
reportSourceType="reportingComponent"
displayGroupTree="false"
        displayToolbarExportButton="true"

        displayToolbarToggleTreeButton="false"
        displayToolbarCrystalLogo="true"
top="100"
left="200"
reportSourceVar="#{Report.reportSource}"
isOwnPage="true"
displayGroupTree="false"
allowDatabaseLogonPrompting="false">
<crviewer:report reportName="Report.rpt">
     <crviewer:partsViewer viewerName="CrystalViewer"
          reportSourceType="reportingComponent"
          title="Fill to Fill Report"
          numberOfRecords="10"
          showHeadings="true"
          showPageNavigationLinks="true"
          allowParameterPrompting="false"
          reportSourceVar="#{Report.reportSource}"/>
</crviewer:report>
</crviewer:viewer>
I am trying to run this and it shows an error page with information Database Login Error.
I have created the report using JDBC/JNDI database connection with trusted authentication = false.
The Sql Server 2005 error log shows -
Error: 18456, Severity: 14, State: 5.
Logon       Login failed for user ''. [CLIENT: <named pipe>]
Any help will really be appreciated.

Yes within the report designer i am able to refresh the report and open and close the report without getting prompted. I am not changing any database properties at runtime and using the jar files which come with CR Release 2.
All i am doing is to export the report in pdf format. Here is the code :
ReportExportControl exportControl = new ReportExportControl();
ExportOptions exportOptions = new ExportOptions();
PDFExportFormatOptions pdfOptions = new PDFExportFormatOptions();
exportOptions.setExportFormatType(ReportExportFormat.PDF);
exportOptions.setFormatOptions(pdfOptions);
exportControl.setExportOptions(exportOptions);
exportControl.setExportAsAttachment(false);
exportControl.setReportSource(this.wrapper.getReportSource());
exportControl.setName(this.wrapper.getReportName());
exportControl.setEnableLogonPrompt(false);
//Pass Fields object to ReportExportControl
exportControl.setParameterFields(this.wrapper.getFields());
//Export only works if i pass the connections object with connectioninfo object populated with username and password.
//We want to run the report using trusted authentication i.e. we don't want to pass username and password.
exportControl.setDatabaseLogonInfos(connections);
if(to_refresh)
exportControl.refresh();
If i don't provide the connectioninfo object with proper username and password to run the report inside the java class, it try's to logon to database using username = 'userid'. I think it picks it from the JDBC Connection String created while creating database connection for the report in the designer.
Here is the jdbc connection string for the JDBC/JNDI connection created inside the report designer:
!net.sourceforge.jtds.jdbc.Driver!jdbc:jtds:sqlserver://localhost:1433/customer;namedPipe=true!user=!password=.
Is there a way to get pass this problem??? Is there a way to force the connection from the java class to use trusted authetication??? Can we change the connection string to replace the userid with empty string to force trusted authetication???
Any help will be really appreciated.

Avoiding Database Logon in Infoview

I created a Crystal Reports using an Oracle Database. Once the report is completed I saved the report in INFOVIEW under a folder. When I try to run the report from InfoView it asks me for
Database Logon again.
I have to enter the user id and Password to make the report run. I want to run the report without asking
Credentials again.

there are 2 methods that can help
1) SSO to the DB which requires Oracles to be integrated with AD(not documented by BO) and BO to be integrated with AD (admin guide)
2) DBuser DBpass also allows a way to use a predetermined user/pw added to a user account in the CMC.I don't think this is documented externally. You will need to open a case and have an engineer check our internal product forums for a solution.

Tim

How to Avoid Save As dialog when Saving

We recently upgraded Adobe Reader X to XI. One difference between the two is the behavior of the Save function the first time it is performed. In Reader X, when Save was selected, the file would simply save the current file, overwriting the original file. In Reader XI, when Save is selected, the Save As dialog box appears, and if the user does not change the file name or path, a warning pops up asking whether the existing file should be overwritten. I understand that this behavior is a result of Protected Mode being enabled. Is there a way to keep PM enabled, but always allow files to be overwritten as was the case in Reader X?

Yes, it does. (as long as the pdf has been opened via a COM interface)

How to avoid pop-up dialog? "Read From Spreadsheet File.vi"

I am using LV2010 and VBAI2011.
I am using LV to write vi for my VBAI user interface. VBAI will send the inspection results to vi by "Update Inspection UI".
I am calling a "Run LabVIEW VI" from within the VBAI. This vi contains a sub-vi "Read From Spreadsheet File.vi"; the "file path" input to this sub-vi is a string control, which will be updated by a string value obtained in previous steps.
What happen is, when I run the Inspection, a windows "Choose File to Read" will pop up, even though I have already update the "file path" in VBAI. I guess this happens because the "Read From Spreadsheet File.vi" sub-vi didn't wait for the "file path" input, or rather the "file path" update was "too slow"
How to prevent this from happening?
Solved!

I didn't use your code but tried the attached simple VIs and they work well. Can you create a simple VBAI interface that just runs these two VIs and see if you are able to replicate the issue? The VIs are LabVIEW 2010 SP1
Attached is my VBAI inteface as well, which is 2011 SP1.

    activate
end tell
display dialog ("completed")
end tell
Thanks,

Does this NOT error when run? Your target application here is 'Finder' Apple's system file browser and you are giving it Adobe illustrator commands?
Im not 100% about the versioning with Illustrator installs I think they are all just…
Tell application "Adobe Illustrator" -- No CS Versioning?
     -- do stuff here
end tell
you could check by just picking the app from this list
