BringWindowToTop Lib "user32" process handling... [RESOLVED]

[Ruku]

I've been using API to bring a window to the foreground but it's not working if it's outside my app... uh, WHY?

Module modWindow
    'Declare API Function
    Private Declare Function BringWindowToTop Lib "user32" (ByVal hwnd As Long) As Long
 
    Public Sub SelectWindow(ByVal hwnd As Long)
        'Bring target window to front
        BringWindowToTop(hwnd)
    End Sub
 
    Public Sub proTst(ByVal AppID As Integer)
        Dim p As System.Diagnostics.Process
        SelectWindow(Convert.ToInt32(p.GetProcessById(AppID).Handle))
    End Sub
End Module

Not working... :s! But the API function works fine with let's say the handle of a form inside my app.... very odd...
