Thanks for your reply. Actually, I do have the service automatically starting during the OS start-up using the method you described. What I want to do is have the service automatically started right after installation (without requiring a reboot). I was eventually able to accomplish this by putting the following code in the ProjectInstaller.vb file. The program "MyApp" is a console application that starts, stops, pauses, etc. the service using various command parameters (in this case, "/start,MyService"). 'Auto-start the service after installation. Dim psInfo As New System.Diagnostics.ProcessStartInfo("C:\Program Files\MyApp.exe", "/start,MyService") psInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden Dim myProcess As Process = System.Diagnostics.Process.Start(psInfo) Thanks, Todd_S

Ohh yes!! its correct u need to write that inside the Postback! and i have a question to u why do u need the dataset in session Never try to load a dataset or a datatable in session it seems urs is a report so it may have more data. more and more data in session makes load to your server which results in a performance issue and i dont think it i srequired also in this scenario!! consider this!!:) Loving Code, R.
