     This code will hook any api of your chose and allow you to redirect it to another qualified function. This code can be used in conjunction with my other posts dealing with process injection to hook api's in other running processes. Thanks for voting!!

  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com

You can solve them this way:

int l;
l = strlen(lpText);
char *msg;
msg = (char*)malloc(l);

But i still can't understand what this code would show...

The code is good, but will only work for the current process, also it breaks the old Functiosn, until you restore the bytes, making socket hooking near impossible, But otherwise good code

Hello,
I know this is old post :)

can you explain(if you are still here ) this line :
DWORD dwCalc = ((DWORD)lpFunction - dwAddr - 5);

why are you subtracting ? why not jmp to lpFunction directly ?
