if using MFC AfxGetInstanceHandle(). For console programs, call GetConsoleWindow() to get the HWND then GetWindowLong() to get the HINSTANCE.
For the Win32 API, you could also use GetModuleHandle():
//get instance of current program (self)
HINSTANCE hInst= GetModuleHandle (0);
获取当前应用程序实例(instance:HINSTANCE)(转)
