I'm new to VB.NET
How do you get the hWnd of a external application by Class Name
Example:
MSBLClass is the Class Name of Windows Messenger
Notepad is the Class Name of Notepad
tSkMainForm is the Class Name of Skype

Thanks for you help.

Hi,

You can use FindWindow, you have to declare this function first

Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal ByVallpClassName As String, ByVal lpWindowName As String) As Integer

After that use this code get the hWnd

        Dim hWnd As Integer
        hWnd = FindWindow("Notepad", vbNullString)
        MsgBox("NOTEPAD: " & hWnd)
