Logon Failure during exporting

Using Crystal Report for VS.Net in one of my .Net project, to connect to Oracle database "myDB" to generate a report. Things seems OK till it hits the "ExportToDisk" method, and gave me a "Logon Failure" exception.

Googled around and somebody said that I have to use "setDatabaseLogon()" method to set the uid/pass during runtime. So I did but it still didn't work.

Here's my source code, hope somebody could shed some light on this. Thanks !

******************************
"myConnection" is an estabilished OleDbConnection that was used repeatedly through the project. "dsTemp" is a dataset
******************************
Dim rptWKIT As New crWKIT()
Dim exportFileName As String = "exportedReport.rpt"
Dim exportPath As String = Application.StartupPath & "\" & exportFileName

Try
dsTemp.Clear()
Dim myDA As New OleDb.OleDbDataAdapter()
Dim myCmd As New OleDb.OleDbCommand()
myCmd.Connection = myConnection
myCmd.CommandText = "SELECT * FROM WKIT"
myCmd.CommandType = CommandType.Text
myDA.SelectCommand() = myCmd
myDA.Fill(dsTemp, "WKIT")

rptWKIT.SetDataSource(dsTemp)
rptWKIT.SetDatabaseLogon(sUser, sPass)
rptWKIT.Load()

rptWKIT.ExportToDisk(ExportFormatType.RichText, exportPath)
Catch x As Exception
MessageBox.Show(x.Message + x.Source + x.StackTrace, "Report Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
End TrySee if you find asnwer here
http://support.businessobjects.com/|||Thanks. I just figured this out... after the rptWKIT.SetDataSource(dsTemp), there's no need to do the next 2 steps:

rptWKIT.SetDatabaseLogon(sUser, sPass)
rptWKIT.Load()

It can just export without any problem. But when do Load() again, guess CR is confused...|||Glad to know you sorted it out :)
