[windev] Windows Hooks / Menus

[Lori Falck]

OK, so we wound up using WM_COMMAND and have this thing working flawlessly.
We can launch an application, grab the window's menu handle, add an item to
it, and capture/process click events on that particular menu item.

But...  (of course there is a but)

The target application doesn't appear to use standard Windows menu controls.
::GetMenu() returns NULL

So we can either:
1) Go to plan B and attach to the System Menu of the application
2) Go for a context menu (there does not appear to be one currently)
3) Try to tackle whatever they are using for the menu - It could be a
MenuBar, but we aren't sure yet
   
I guess my question to you all is - is it worth the time to keep digging
into the main menu?  Is there hope?

Does anyone have any experience tapping into a CMenuBar in another
application?  Is there anything else it might be?

Thanks!!

Lori

That's exactly how I'd do it.

Your message hook proc should get exactly the MSG structure that will be
unpacked and sent through the window proc chain, so it includes everything
you need to decipher it.

Caveat: I haven't used this feature since before Vista, so I don't know how
or if the added security features there have changed the way it works.
