C++ ? Source:

Code:

static const FARPROC SCP = (FARPROC)((DWORD)GetProcAddress(GetModuleHandle("user32.dll"), "SetCursorPos" )+5);

_declspec(naked) BOOL WINAPI SetCurPos(int x, int y)
{
_asm
{
   mov edi,edi
   push ebp
   mov ebp,esp
   jmp [SCP]
}
return 0;
}

Source:

Code:

#include <Windows.h>

DWORD _SCP = 0;
__declspec(dllexport) __declspec(naked) BOOL WINAPI _SetCursorPos(__in int X, __in int Y)
{
__asm
{
   push ebp
   mov ebp, esp
   jmp dword ptr [_SCP]
}
}

BOOL WINAPI DllMain(HMODULE hModule, DWORD dwReason, LPVOID lpReserved)
{
_SCP = (DWORD)GetProcAddress(LoadLibrary(_T("user32.dll")), "SetCursorPos") + 5;
return TRUE;
}

Then make a .def file and put

LIBRARY SetPos
EXPORTS _SetCursorPos @1

(^ If i remember correctly...)

I find that C++ makes a bigger file than delphi. Cause I made a pmx in C++ and it gave me 300kb while delphi's pmx gave me around 80kb.

Depends on the compiler and optimization level. _________________ Mutilated lips give a kiss on the wrist of the worm-like tips of tentacles expanding in my mind I'm fine accepting only fresh brine you can get another drop of this yeah you wish

And whether or not you link the CRT.

I use MSVC++ 2k8, and in C it gives me 7.0kb, in Delphi (when i remove unused imports) it can give me 25kb (or more, around that).

Try this, not sure, long time since i did this last...

Code:

static const FARPROC SCP = (FARPROC)((DWORD)GetProcAddress(LoadLibrary("user32.dll"), "SetCursorPos" )+5);

_declspec(naked) BOOL WINAPI SetCurPos(int x, int y)
{
_asm
{
   mov edi,edi
   push ebp
   mov ebp,esp
   jmp [SCP]
}
}

Otherwise, take a look at this:
