Write a proxy.dll

[little_Coder]

Hello I want to write a proxy.dll
It is not ment a socksproxy.
I mean a dll which has exactly the same functionnames as in the original dll
e.g.
in the kernel32.dll is ExitWindows
When I want to filter ExitWindows to block ExitWindows, I write a kernel32.dll which has an modified ExitWindows, but the other functions will be just relayed to the real kernel32.dll
So like this

An Application --> ExitWindows --> kernel32.dll (proxy) -->ExitWindows--> copykernel32.dll (real)


Does somebody has a sample source?

Thx

You don't need to filter ExitWindows, just return FALSE in reply to the WM_QUERYENDSESSION message.

Whats the point of this all?
If you are so good in OpenGL then go create better some game in ASM. And work on this "project".
And you will learn more.

I agree, if it's just for learning it's probably a little too complex. You're better off following NeHe's tutorials instead.
