hi, i have a question about changing the DataSource in rpt file point from Development to production.
i am now using VS2008 to write a dot net window program (in c#).The app is used to drive 7 Crystal Report 2008 (sp2) rpt file. this window application has a drop down menu to select either dev database or prod database to generate the report. and the part (code) for change the datasource has been shown below:

private void setDBLogonForReport(ConnectionInfo info, ReportDocument doc)
        {
            Tables myTables = doc.Database.Tables;
            foreach (Table myTable in myTables)
            {
               TableLogOnInfo logOnInfo = myTable.LogOnInfo;
               logOnInfo.ConnectionInfo = info;
               logOnInfo.TableName = myTable.Name;
               myTable.ApplyLogOnInfo(logOnInfo);
               //myTable.Location = info.UserID + "." + "pkg_CR." + myTable.Name;
            }
}

i found that it will show Vendor error(6550) and
it cannot change the ServerName after the function ApplyLogOnInfo(...). it still use the setting which i use for design the report. is it a bug for CR2008? i have already applied the service pack 2.
more info: this win app is connecting to oracle procedure and "pkg_CR" is a package name. this procedure will return ref_cursor so report can read ref_cursor data to generate report.

I have the same problem. Do you have a solution? all help much appreciated.
