Hey

You've found you can AppendMenu, but when you SetWindowLong (with the other apps window hwnd, and your WindowProc) is returning zero - correct?

You will need to use Hooks to respond to the WM_SYSCOMMAND from the other app. You cannot do this in VB, as you need to create a dll (c++) that is injected into a foreign process space. Once you have this dll, it can call your custom window proc (as in normal subclassing). After your processing, your proc uses the dll to pass back to any other Global Hooks knocking around.

I can recomend a v.good book.

Win32 API Programming with Visual Basic. (O'Reilly, ISBN 1-56592-631-5).

To start friggin around with this kind of stuff, really does take balls, you will need a reference like this to do it (This is the kind of stuff that can give Dan Appleman a bad day). It is written by a guy called Steven Roman.

It comes with a dll to do what you want to do, and examples.

I can send you the dll. But i really recomend you DON'T try this stuff without reading up on it. It's not just a question of using the DLL, you really have to know stuff that's going on under the hood.

The deadline is looking at me...I hope i have good understanding of message subclassing. will this help doing that..please help...now u r the only one who can help me..if u could do some help on how to use this dll then i would be very thankful to u

i'm facing deadlines myself (already missed one). I know how your position. If you know subclassing, then you should be able to digest the two chapters in an hour. Amazon should be able to deliver within a day...

I can mail you dll if you want, but your on your own (at least till i'm not so busy).
