ok i deleted my .h files and .def file
after that my cpp file was compileable
then i added a new header file and called it myHeader.h
i wrote in it:

Code:

#ifdef __cplusplus
extern "C"
{

#endif

__declspec( dllexport ) bool PostMessage2(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);

#ifdef __cplusplus
}
#endif

now when i compile it i get warning message at the bottom
frame pointer register ebp modified by inline assembly code (but i dont think it matter).

now i #include "myHeader.h" in dllmain.cpp
compiled it and succeeded
in my application i imported the function from my dll and when i run it i get
"attempted to read or write protected memory. this is often an indication that other memory is corrupt"

just do this !!

dllmain.cpp

Code:

#include "windows.h"

DWORD hPMA = (DWORD)GetProcAddress(LoadLibraryA("user32.dll"),"PostMessageA")+5;
DWORD hGPA = (DWORD)GetProcAddress(LoadLibraryA("gdi32.dll"),"GetPixel")+5;

__declspec(naked) void PMA(void)
{
__asm
{
mov edi,edi
push ebp
mov ebp,esp
jmp [hPMA]
}
}

__declspec(naked) void GP(void)
{
__asm
{
   mov edi,edi
   push ebp
   mov ebp,esp
   jmp [hGPA]
}
}

Exports.def

Code:

LIBRARY PMX2
EXPORTS
PMA @1
GP @2
