I want to use the sendmessage api call to a window in order to maximize it. I have determined the WindowHandle by using the findwindow Api call.
The Sendmessage api call requires 4 parameters
The first one is the window handle, second one is the message (I send WS_MAXIMIZE, third and fourth ones are wparam and lparam and are defined in the API bible as type Long and value depends on the message. I can`t find out where to look for the value to pass to these parameters for the WS_MAXIMIZE message. Can anyone help?

Thanks.
