My question is how to globally hook some function from any other dll (kernel32, user32, winsock). I watched madCodeHook but it allows me only to hook a function in one process only. And it would be fine if it worked on W2k/XP too ;-))

I offer +500 points for a complete solution...

So you want to hook into the Windows API globally?  Sounds like a RootKit.  ;-)  Check out http://rootkit.com/ for some examples, with source code.  Not in Delphi, but the API's are the same.

You can use the latest beta version of madCodeHook which supports system wide dll injection in both 9x and NT families. This way you can quite easily realize system wide API hooking. Here's the download:

Here are some demos which demonstrate how you can use madCodeHook to do system wide API hooking:

It is realy cool, but I have one problem while compiling the dll:

begin
  DllProc := @HandleEvents;
  DllProc(DLL_PROCESS_ATTACH); // -> Missing operator or semicolon
end.

I'm using D5, in my case
var DllProc: Pointer
 in SysUtils

Oh, interesting, thanks for the hint. Then please change it to:

HandleEvents(DLL_PROCESS_ATTACH);

I'll change it in my sources, too.
