Question

Opening Crystal Report using VB Application

Asked by: mrsompura

I'm working with crystal report and Visual Basic. I'm using Crystal Report for the first time.

I need help on how to call crystal report file (.rpt) file using Crystal Report Viewer Control using VB Application.

I have added required references to my vb project. I've also created report using Crystal Report and saved it in Report Folder where my application will be installed.

I'm using MS SQL Server as backend. I'm using Crystal Report 8.5.

I have added Crystal Viewer Control in one Form. What code i need to write to open the report without any error and updated data?

Can any one provide me sample application? Please Help. It is urgent. I'm new guy for Crystal Report.

Thanks,

Rakesh Sompura.

You can get the sample apps here:
http://support.businessobjects.com/communityCS/TechnicalPapers/apps_rdc.pdf.asp

If you're using the RDC, here is the minimum code you need to run a report against SQL Server:

'General Declarations
Dim crxApp As New CRAXDRT.Application
Dim crxRpt As CRAXDRT.Report

Private Sub Form_Load()

'Open the report
Set crxRpt = crxApp.OpenReport(App.Path & "\Reports\Profile.rpt")

'Clear any saved data to force to report to read from the db
crxRpt.DiscardSavedData

'Set the connection for the report.
crxRpt.Database.Tables(1).SetLogOnInfo "ServerOrDSNName", "DBName", "UserID", "Password"

'View the report
CRViewer.ReportSource = crxRpt
CRViewer.ViewReport

Looks good.  For deploying if you are using InstallShield there are merge modules to ease the process

Thank you for the code. I've written the same code that you have pasted above.

When I'm trying to open the report it gives me the error "Server has not been yet started".

Do you have any idea why it gives this error?

I've created DSN also but still it gives the same error.

One More thing i want to ask that Which type of database i need to choose while creating reprot in Crystal Report 8.5?

Do I need to choose ODBC or SQL Server Database from More Database Option.

I'm using Crystal Report Expert and Standard Report Format.

Please Help!

Thx,

Rakesh Sompura

"Do I need to choose ODBC or SQL Server Database from More Database Option."
 That's up to you.  ODBC would give you a bit more flexibility since it wouldn't be absolutely necessary to have the SQL Server client components installed to connect.

This document contains many of the reasons for the 'Server Not Yet Opened' error.  I suggest you have a look at it.
http://support.businessobjects.com/communityCS/TechnicalPapers/cr_server_not_yet_been_opened.pdf.asp

One of the potential issues mentioned in the above whitepaper deals with the database schema being saved with the report file.  This happened to us at some point when we started renaming our databases something other than the default name.  The temporary fix was to open up each report, go to Database > Set Location, and remove the schema from the table names (e.g. change 'DBName.dbo.TableName' to just 'TableName').  The runtime solution was to remove the schema at runtime by parsing DatabaseTable's Location property:

'Loop through the report's tables, set the LogOnInfo, and erase schema, if necessary
Dim crxTable As CRAXDRT.DatabaseTables
For Each crxTable In crxRpt.Database.Tables
   crxTable.SetLogOnInfo "ServerOrDSNName", "DBName", "UserID", "Password"
   If InStr(crxTable.Location, ".dbo.") > 1 Then
      crxTable.Locaton = Split(crx.Location, ".")(2)
   End If
Next crxTable

Once the schema is gone, if you're using an ODBC connection, it will should the default database of the ODBC connection.

The other option you could look at is to use an OLE connection.  The code dave supplied will still work but you don't need to setup the ODBC connection or have the SQL client.

We have the reports in Crystal Report 8.5 the reports have them connected directly with Database Files referring to a direct base of information in Access. This report we want that it(he,she) generates it both for Access and for SQL Server. That we must do.
