Hi,
Actually, I'd like to know whether a mouse click was inside a menu (or a menu item). I thought that WM_LBBUTTONDOWN will give me the mouse click coordinates, and that MenuItemFromRect() will give the menu item selected.

However, this does not work (at least not always). I've tried to find an example of using MenuItemFromPoint() or GetMenuItemRect(), but I couldn't find any.

Do you have any idea?

Thanks,

You cant dispatch WM_LBUTTONDOW while menu activated.  Becouse menu is WINDOW , sysmodal window. It have  mouse and keyboard capture. All messages translating to menu`s window and dispatching by it. What why you cant work with mouse /keyboard messages when menu opened :-( Try to use other way to do what you want.

I didn't fully understand your answer. Perhaps I should elaborate a little more.

I'm already receiving WM_LBUTTONDOWN from the window. At that point I would like to know whether the mouse click was inside or outside a menu.

However, it seems that the coordinates used by the menu functions  - MenuItemFromPoint() and GetMenuItemRect() - use coordinates which do not correspond to the mouse click coordinates.

If someone has any experience using these functions, please tell me ...

What king of menu you using ?
About cooridinates not corresponding to other. WM_LBUTTONDOWN point coordinates relative to the upper-left corner of the client area of the Window. GetMenuItemRect function return coordinates expressed in screen coordinates.
You should you ClientToScreen And ScreenToClient function to convert coordinates
