Hello, I have the following codes and received
System.NullReferenceException which I don't understand why.
Please help me on this.
Thank you. (I use Visual Studio 2003.)

Dim fbdFolderSelection As FolderBrowserDialog
fbdFolderSelection = New FolderBrowserDialog
Try
fbdFolderSelection.ShowDialog()
strMainDir = "MAINDIR=" & fbdFolderSelection.SelectedPath.ToString()
'strMainDir = "MAINDIR=c:\"
Catch ex As System.NullReferenceException
strMainDir = "MAINDIR=" & fbdFolderSelection.SelectedPath.ToString()
End Try
