Thanks for the reply. I think it's the same function as OnKeyDown(). Can I monitor SHIFT and CTRL with it?

Sorry ignore my previous reply. It's for ATL combination keys. Clickety[^]

    `BOOL bCtrl = ::GetKeyState(VK_CONTROL); 	BOOL bAlt = ::GetKeyState(VK_SHIFT); 	BOOL bShift = ::GetKeyState(VK_MENU);`

This will help you to know the combination keydown tracking.

though it is the nice way to get key state, but you have poll this thing every time to get state of the key.,

I tried your code inside OnKeyDown() event but the result is unpredictable. if(::GetKeyState(VK_CONTROL)) AfxMessageBox(L"CONTROL"); if(::GetKeyState(VK_SHIFT)) AfxMessageBox(L"SHIFT"); if(::GetKeyState(VK_MENU)) AfxMessageBox(L"ALT"); When ALT is pressed, either no display or wrong message(CONTROL or SHIFT) CONTROL and SHIFT sometimes correct but sometimes display all. Did i do something wrong? How will i use the code?

Try this...

      BOOL bCtrl = ::GetKeyState(VK_CONTROL)& 0x8000;
      BOOL bShift = ::GetKeyState(VK_SHIFT)& 0x8000;
      BOOL bAlt = ::GetKeyState(VK_MENU)& 0x8000 ;
