Given a handle, differentiate between a window and a control

Recommended Posts

Hi

If I have a handle, is there any way to tell if it's referencing a Control or a Window? I know that a Control is just a window but I need to be able to tell the two apart and send different messages depending on which one they are. WindowInfo seems to be able to tell the difference but I can't figure out how it's doing it. Sorry if this is a stupid question.

How are you getting the handle if you don't know where it's coming from? If you have the handle, generally you've used a function to get it, WinGetHandle gets window handles, ControlGetHandle gets control handles. Also, the AU3Info program will only show control handles on the controls tab, and window handles on the window tab.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Hi, I got the handle by enumerating child windows, that's why I don't know if it's a real window or a control.

I think GetDlgCtrlID does what I want it to do. It seems to anyway.

Although the Class name idea could be good too. Quick googling turned up:

I was hoping to not have to case through a bunch of types though...

Look here at CreateWindow function at hMenu parameter description:

http://msdn.microsoft.com/en-us/library/windows/desktop/ms632679%28v=vs.85%29.aspx

hMenu [in, optional]

Type: HMENU

A handle to a menu, or specifies a child-window identifier depending on the window style. For an overlapped or pop-up window, hMenu identifies the menu to be used with the window; it can be NULL if the class menu is to be used. For a child window, hMenu specifies the child-window identifier, an integer value used by a dialog box control to notify its parent about events. The application determines the child-window identifier; it must be unique for all child windows with the same parent window.
