Changing Connection parameters in a Crystal 11 report

I have a crystal 11 report, running from a SQL server stored procedure.

I am using VB6 code to run the report.
I am using CRAXDDRT in the VB6 project.

I am using the ConnectionProperties of the table to set the security, server and initial catalog.

the problem is, if I want to change the name of the SQL server database (for upgrading purposes), the report still attempts to connect to the old database name.

This is causing a problem because if the original database does not exist the program will not run.

Any ideas?

Does your report have subreports?

The subreport connection properties are being set using the same logic as the main report.

This is the code i am using to set the connection paramrters for each table in the report/subreports :

I took this from the Crystal Reports Technical reference guide . pdf

Private Sub SetTableLogonInfo(i_objReportTable As CRAXDDRT.DatabaseTable)

Dim objConnectionProperty As CRAXDDRT.ConnectionProperty
Dim strLocation As String

        Set objConnectionProperty = i_objReportTable.ConnectionProperties("Integrated Security")
        objConnectionProperty.Value = True
       
    'Get the Datasource Property of the Table and set it with the server name
    Set objConnectionProperty = i_objReportTable.ConnectionProperties("Data Source")
    objConnectionProperty.Value = m_strServerName
   
    'Get the Initial Catalog Property of the Table and set it with the database name
    Set objConnectionProperty = i_objReportTable.ConnectionProperties("Initial Catalog")
    objConnectionProperty.Value = m_strDatabaseName
   
    Exit Sub

I have managed to fix this.
I have used the following code :

i_objReportTable.ConnectionProperties.Delete
i_objReportTable.ConnectionProperties.Add "Integrated Security", True
i_objReportTable.ConnectionProperties.Add "Data Source",m_strServerName
i_objReportTable.ConnectionProperties.Add "Initial Catalog",m_strDatabaseName
i_objReportTable.ConnectionProperties.Add "Provider","SQLOLEDB"

Seems to work ok using this method.

Not too sure why i have to delete and recreate the connection properties for reports that run from a stored procedure.

Reports that run from SQL tables worked with the previous code.
Strange!

NOt sure either unless there is some difference in a connection to an SPP when compared to a view or table.
