Hi Experts,

I have several Crystal Report XI reports that I automate through VB.Net.  These reports point to an Access database.  I need to store the path to the access database mdb file as a setting and then set the data source location at run-time with my VB code.

How do I do this?

Thanks

Hi Habibb,

That's not exactly what I was looking for.  That example uses VB6 with the CRXDRT DLL which I've used a lot in the past.  What I'm trying to do with Access now I can already do with SQL Server, see example below:

  Public Sub SetReportConnections(ByRef XReport As ReportDocument)
    Dim CInfo As New ConnectionInfo
    Dim t As Table
    Dim TLogonInfo As TableLogOnInfo
    Dim SubR As New ReportDocument


    'Set the connection
    CInfo.ServerName = ServerName
    CInfo.DatabaseName = DatabaseName
    CInfo.UserID = UserID
    CInfo.Password = Password

    'Set Logon details for main report and each table inside the main report
    For Each t In XReport.Database.Tables
      TLogonInfo = t.LogOnInfo
      TLogonInfo.ConnectionInfo = CInfo
      t.ApplyLogOnInfo(TLogonInfo)
    Next

    For Each SubR In XReport.Subreports
      For Each t In SubR.Database.Tables
        TLogonInfo = t.LogOnInfo
        TLogonInfo.ConnectionInfo = CInfo
        t.ApplyLogOnInfo(TLogonInfo)
      Next
    Next

  End Sub


This procedure explicitly sets the connection details for a report file that connects to SQL Server.  Now I need to do exactly the same with MS Access but I'm assuming that different objects / properties / methdos must be used.

From the example in the link I basically need to copy the following logic:
Dim CRXDatabase As CRAXDRT.Database
Set CRXDatabase = CRXReport.Database
CRXDatabase.SetDataSource rs, 3, 1

I'm not using the CRXDRT so this syntax won't work.  I can't find the syntax to perform this logic. I need to find the exact syntax for the components that I'm using.  I'm using the CrystelDecisions .Net references.

Thanks

Thanks habibb,

From the example provided I got the following:

cr1.ReportFileName = App.Path & "\reports\ot1.rpt"
cr1.DataFiles(0) = App.Path & "\otmanag.mdb"

I'm assuming that cr1 is a ReportDocument?  My reportdocument doesnt have a DataFiles property.  I assume the example also uses a different version of the Crystal API than I am.  As in the very first example, this is exactly the logic that I'm trying to perform, only the syntax doesn't fit my API.

Is there perhaps an API guide for the Crystal Reports XI R2 .Net references?

Thanks

Please find below information copied from http://diamond.businessobjects.com/node/134
If you are connecting to Access through OLE DB,
then set the 'ServerName':

With crConnectionInfo
.ServerName = "C:\mydatabase\mydata.mdb"
End With
