With the Girder, we can get class name, file name, wParam and lParam of any softaware. But I would like to know the number of wMsg to use the window API SendMessage (hwnd, wMsg, wParam, lParam)

I think either the wMsg is written somewhere on Girder (in a form, or a temporary file, or a variable...), either by using an API with class name and file name as extension.

How can i get the wMsg ???
