And you just call PostMessage? or is it a variant of it?

Good work as always, Irwin! This will definitely come in handy.

But if it doesn't have the prologue and you only jump over 3 bytes, won't it try to execute the last 2 bytes of the hook?

Would this allow trampolining for any start of a function even if it doesn't use mov ebp, esp, etc?
| Code: | __declspec(naked) BOOL WINAPI _PostMessage(__in HWND hWnd, __in UINT Msg, __in WPARAM wParam, __in LPARAM lParam)
{
__asm {
//20 or so nops lol
jmp [ulPostMessage]
}
}
__inline BOOL InitializeTrampoline(void)
{
__try {
ulPostMessage = (ULONG_PTR)PostMessage;
do{
ulPostMessage += anArrayOfOpcodeLengths[*(BYTE*)PostMessage];}
while(ulPostMessage < (ULONG_PTR)PostMessage+5)
*(BYTE[ulPostMessage-(ULONG_PTR)PostMessage]*)_PostMessage = *(BYTE[ulPostMessage-(ULONG_PTR)PostMessage]*)(ULONG_PTR)PostMessage;
return TRUE;
}
__except(EXCEPTION_EXECUTE_HANDLER) {
return FALSE;
}
} |

| Can't you just make a function that disassembles first few bytes of the API and copy the appropriate number of bytes for the trampoline?

| It's really weird how whenever Irwin creates something and posts it, the upload always has to have a homosexual description included no matter what it is.

Thank you for the example, while I do not truly understand it, I have bookmarked it for later reference in hopes of one day successfully being able to implement/understand a trampoline.
