hey guys, im working on my bot in C++

i've got this so far:
Code:
HWND mswin;
DWORD lParam;
INT scancode;
INT key;
INT on;

void sendshit(INT key)
{
   mswin = FindWindowW(L"MapleStoryClass", NULL);

   lParam = MapVirtualKey(key,0);
   lParam <<= 16;

   PMX(mswin,WM_KEYDOWN,key,lParam);
   Sleep(10);
   PMX(mswin,WM_KEYUP,key,lParam);
}


bool Keys(void) // Main code
{
   if (on == 1){
      sendshit(0x45);
      Sleep(300);
   }

   if (on == 0){
      Sleep(1000);
   }
   return true;
}

bool HotKeys(void) // Main code
{
   for(;;) // Main loop
   {
      Sleep(20);

      if(GetAsyncKeyState(VK_F6) && (on == 0)) {
      on = 1;
      CreateThread(0, 0, (LPTHREAD_START_ROUTINE)&Keys, 0, 0, 0);
      Sleep(400);
      }

      if(GetAsyncKeyState(VK_F6) && (on == 1)) {
      on = 0;
      Sleep(400);
      }

   }
return true;
}


BOOL WINAPI DllMain( HMODULE hModule, DWORD dwReason, LPVOID lpReserved )
{
   switch ( dwReason )
   {
   case DLL_PROCESS_ATTACH:
      on = 0;
      CreateThread( 0, 0, (LPTHREAD_START_ROUTINE)HotKeys, 0, 0, 0 );
      break;
   case DLL_PROCESS_DETACH:
      break;
   }

   return 1;
}

I'm sorry I'm no real help to your problem, but I felt I needed to ask.

Why would globalhotkeys bebetter to use the GetAsyncKeyState?

because keystate requires checking every 20 ms or so

i believe hotkeys are just called when keys are pressed, less cpu usage

are you calling PMX from an external dll?

Edit:

For Global hotkey's

define an ATOM and call GlobalAddAtom("some random string");

then use RegisterHotKey

It'l look like this:

Code:
ATOM HotKey1;
...
HotKey1 = GlobalAddAtom(_T("Hotkey"));
RegisterHotKey( hWnd, HotKey1, MOD_CONTROL, VK_F11 );


hWnd - your window to handle the message (WM_HOTKEY)
HotKey1 - The ATOM you defined and added.
MOD_CONTROL can be NULL if u dont want a mod key (shit,ctrl,or alt)
VK_F11 is edited for w/e hotkey you want.

then check for WM_HOTKEY in your WndProc

Code:
case WM_HOTKEY:
    switch ( HIWORD(lParam) )
    {
        case VK_F11:
               sendshit();
               break;
    }

hmm..

looks like this right?

Code:
DWORD dwPM = (DWORD)GetProcAddress( LoadLibrary( _T("user32.dll") ), "PostMessageA" ) + 5;
_declspec(naked) BOOL WINAPI PMX( HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam )
{
   _asm
   {
       mov edi,edi
       push ebp
       mov ebp,esp
       jmp dword ptr ds:[dwPM]
   }
}


It might be that your not exiting your threads... if they don't already exit if you dont call ExitThread, not really sure about that one....

Btw read my post above about Global Hotkeys

_T is a macro for UNICODE..

if your not using a UNICODE charecter set you can get rid of it, if you are add tchar.h
