App Previous Instance with Windows NT

[Joacim Andersson]

I don't know if I understand you correctly but if you want to check for a previous instance of your app use the following code in the Load event of your main form.

Private Sub Form_Load()
    If App.PrevInstance = True Then
        'a previous instance of this
        'application is running
    End If
End Sub

This works on both Win9x and WinNT.
Good luck!
