Here's an example of bypassing PostMessageA (from 1gaz's source of hBot.cpp).

Code:

void LoadUser32()
{
   hpInst = LoadLibrary("User32.Dll");
   pmDLLFunc = NULL;
   if (hpInst != NULL)
      pmDLLFunc = (DWORD)GetProcAddress(hpInst,"PostMessageA");
   if (pmDLLFunc != NULL)
      pmDLLFunc += 5;
}

__declspec(naked) BOOL WINAPI PostMessageX(HWND hWnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
   __asm
   {
      mov edi,edi
      push ebp
      mov ebp,esp
      jmp dword ptr ds:[pmDLLFunc]
   }
}

//more coding

LPARAM lParam = (MapVirtualKey(0x5A, NULL) << 16);
PostMessageX(hMS, WM_KEYDOWN, 0x5A, lParam);

I tried this, but for some reason it doesnt work for me. heres what i tried:
Code:

HMODULE hpInst;
 UINT pmDLLFunc;

// some code

void LoadUser32()
{
 
  hpInst = LoadLibrary("User32.Dll");
   pmDLLFunc = NULL;
   if (hpInst != NULL)
      pmDLLFunc = (DWORD)GetProcAddress(hpInst,"PostMessageA");
   if (pmDLLFunc != NULL)
      pmDLLFunc += 5;
}

__declspec(naked) BOOL WINAPI PostMessageX(HWND hWnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
   __asm
   {
      mov edi,edi
      push ebp
      mov ebp,esp
      jmp dword ptr ds:[pmDLLFunc]
   }
}
void AutoLoot (HWND thisHwnd)
{
   LPARAM lParam = (MapVirtualKey(0x5A, NULL) << 16);
   PostMessageX(thisHwnd, WM_KEYDOWN, 0x5A, lParam);
       if (autoLootStop)
        {
   ExitThread(0);
        }
}
 
//Some more code

CreateThread( NULL, 0, (LPTHREAD_START_ROUTINE)AutoLoot, hWnd, 0, 0 );// this is called on a hotkey press

Which is almost exactly the same. Where did i go wrong? =/.

You declared pmDLLFunc as a UINT type varaible, when then you assign it a DWORD value. Change it to:

Code:

DWORD pmDLLFunc;

KittonKicker made a driver to bypass SendInput and PostMessage, search it. It is very simple to use. But if you are using the SendInput to change the cursor position, then you have a problem.

Ok im going to spoonfeed you

Code:
#define VK_Z 90

DWORD dwPostMessage = (DWORD)GetProcAddress( GetModuleHandle( "user32.dll" ), "PostMessageA" ) + 5;
HWND sHandle = FindWindow("MapleStoryClass", NULL);

BOOL WINAPI __declspec(naked) PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{
   __asm {
      push ebp
      mov  ebp, esp
      jmp dwPostMessage
   }
   return TRUE;
}

void SendKey(UINT vk_key) {

   skey = MapVirtualKey(vk_key, 0);

   lparam = (skey << 16) + 1;

   PostMessageX(sHandle, WM_KEYUP, vk_key, lparam);
}

void AutoLoot()
{
   SendKey(VK_Z);
}


For MS already.

Trying out KiInput now. Instead of adding the KiInput.h file to my project, i just transferred the code within it. But now, when i call Initialize() it tells me that the DLL is missing. Ive placed both the DLL and the driver file everywhere within the project folders, so i dont quite understand why it cant find it. Should i place them somewhere else?
Edit: oh thanks GMZorita, very much appreciated.

I sugest you to do something like
Code:

while (sHandle = NULL)
{
     sHandle = FindWindow("MapleStoryClass", NULL);
}

OK, im getting a little tired off not getting any results.
Btw GMZorita, isnt
"BOOL WINAPI __declspec(naked) PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)" supposed to be "__declspec(naked) BOOL WINAPI PostMessageX(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)" and shouldnt"PostMessageX(sHandle, WM_KEYUP, vk_key, lparam);" have been ""PostMessageX(sHandle, WM_KEYDOWN, vk_key, lparam);"?
Edit: Finally got it to work after realizing i was lacking a "=". Thanks again GMZorita and oib111.

I"m not sure, but I think you have to use the KiInput.h. Also in your main.cpp you should have this code:

Code:
#include "KiInput.h"


Oh wait, I didn't read the second sentence...

If you are using MSVC++ then have the KiDriver and KiInput.dll in your folder with another folder called "Debug".

How would I call Autoloot?

void Autoloot(); would call it, right?

Definitely learn the basics of C(++) before you try to do this...


Also...
Is MAPVK_VK_TO_VSC defined as 0?

GMZortia is helping a nub :D

How bout hotkeys? like

Mostly:
Code:
if( GetAsyncKeyState( VK_F12 )&1 )
AutoLoot();
}
