Open file dialog not showing network locations

[pandehrushikesh]

I am doing setup project in VS 2008. I used custom action to select file from local drives. On the button click of custom action form, I am launching Open file dialog as

ofdGetNetPath.ShowDialog
When I run the setup on Vista, and click the button to open the openFileDialog, it hanged, form becomes non responsive and I have to cancel the setup.

on debugging I got following error
"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your main function has STAThreadAttribute marked in it. This exception is only raised if a debugger is attached to the process."

so I used the following code:

Dim ofdThread As Thread
 
ofdThread = New Thread(New ThreadStart(AddressOf ShowOpenFileDialog))
 
ofdThread.SetApartmentState(ApartmentState.STA)
 
ofdThread.Start()
 
Private Sub ShowOpenFileDialog()
          Me.ofdGetNetPath.ShowDialog()
End Sub

now on button click, OpenFileDialog is shown but it is not showing Mapped drive or Network location... what should I need to do to show the mapped drive or network locations?

This isn't making sense to me.

Why are you using an OpenFileDialog in a thread to begin with?

I have to use thread becouse if I directly launch the open file dialog (ofdGetNetPath.ShowDialog) in the custom action, it gives following error

"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your main function has STAThreadAttribute marked in it. This exception is only raised if a debugger is attached to the process."
