hi,

I am running a windows service witch i want to create a pdf out of the data in the UltraWinGrid on a weekly basis.

The problem is setting the datasource in the grdReport.

 (Me.grdReport.DataSource = Database) 

The service doesnt crash,but the datasource wont update it remains empty. I think the problem is that it tries to create a "hidden GUI window", but a dont think a service is allowed to create a GUI window.

Does anybody know how to fixs this or is there another way of creating a pdf, perhaps without using GUI elements?

The code is something like this:

Protected Overrides Sub OnStart(ByVal args() As String)
 aTimer = New System.Timers.Timer(30000)
 AddHandler aTimer.Elapsed, AddressOf OnTimedEvent
 aTimer.Enabled = True
End Sub

Private Sub OnTimedEvent(ByVal source As Object, ByVal e As ElapsedEventArgs)

..... database connection....

  Dim strFileName As String = "c:\test\test2.pdf"
  Me.grdReport.DataSource = Database
  Me.expPdfExporter.Export(grdReport, strFileName, UltraWinGrid.DocumentExport.GridExportFileFormat.PDF)
Catch ex As Exception

End Try
