[windev] Windows Hooks / Menus

[Lori Falck]

Apologies, but my post from earlier was a bit of a false alarm.  This isn't
my project (I'm helping my hubby since I do way more C++ than he does) and
the window he actually needs to get the menu for he can.

Of course he just called me to let me know it DOES work on the needed
windows, but... it blows up now when he processes the menu click.  So I know
what I'll be looking at tonight...

Thanks for reading,

Lori

You can use Spy++ to see what the menu is - do a "Find Window" and drag
the finder tool over the menu on the app you're trying to hook.  Whether
or not you have any exposed APIs/hooks is another matter, but you can
use Depends.exe for that.  DevEnv.exe uses MsoCommandBar, iTunes just
uses static text for its menu, IE uses ToolbarWindow32.

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.
