WINCE hook技术实例

  WINCE 上不支持直接调用HOOK,只能取函数的地址.原因暂时不说

#define WH_KEYBOARD_LL  20            /* Windows - 14; Windows CE - 20 */
#define HC_ACTION           0             /* Windows - in winuser.h */
typedef LRESULT (CALLBACK* HOOKPROC)(int nCode, WPARAM wParam, LPARAM lParam);

typedef HHOOK  (WINAPI *_SetWindowsHookExW)(int, HOOKPROC, HINSTANCE, DWORD);
typedef LRESULT (WINAPI *_CallNextHookEx)(HHOOK, int, WPARAM, LPARAM);
typedef LRESULT (WINAPI *_UnhookWindowsHookEx)(HHOOK);

static _SetWindowsHookExW SetWindowsHookEx;
static _UnhookWindowsHookEx UnhookWindowsHookEx;
static _CallNextHookEx CallNextHookEx;

LRESULT CALLBACK KeyboardProc(int nCode, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain( HINSTANCE hInstance,
     HINSTANCE hPrevInstance,
     LPTSTR    lpCmdLine,
     int       nCmdShow)
{
  // TODO: Place code here.

 if (g_hHookApiDLL = LoadLibrary(_T("coredll.dll")))
 {
  SetWindowsHookEx = (_SetWindowsHookExW)GetProcAddress(g_hHookApiDLL, _T("SetWindowsHookExW"));
  UnhookWindowsHookEx = (_UnhookWindowsHookEx)GetProcAddress(g_hHookApiDLL, _T("UnhookWindowsHookEx"));
  CallNextHookEx = (_CallNextHookEx)GetProcAddress(g_hHookApiDLL, _T("CallNextHookEx"));
  if ( SetWindowsHookEx == NULL
   || UnhookWindowsHookEx == NULL
   || CallNextHookEx == NULL)
  {
  // AfxMessageBox(L"failed!");
   return FALSE;
  }
 }
 else
 {
  //AfxMessageBox(L"Null . failed! ");
  
  return FALSE;
 }

 //AfxMessageBox(L"OK! ");
 return 0;
}

LRESULT CALLBACK KeyboardProc(int nCode, WPARAM wParam, LPARAM lParam)
{
 int a = 12;
 return 0;
}
