Re: Detecting Ctrl from OnKeyDown?

I wrote a utility function years ago and have never had to worry about it
since:

//===
// In a universally available header file:
//===

const UINT KBD_NONE = 0x00000000;
const UINT KBD_ALT = 0x00000004;
const UINT KBD_CTRL = 0x00000002;
const UINT KBD_SHIFT = 0x00000001;

const UINT KBD_CTRLSHIFT = (KBD_CTRL|KBD_SHIFT);
const UINT KBD_ALTCTRL = (KBD_ALT|KBD_CTRL);
const UINT KBD_ALTSHIFT = (KBD_ALT|KBD_SHIFT);
const UINT KBD_ALTCTRLSHIFT = (KBD_ALT|KBD_CTRL|KBD_SHIFT);

//===
// In my utilities library:
//===

UINT KeybdAltCtrlShift()
{
   UINT uResult = 0;

   if( GetKeyState( VK_MENU ) & 0x8000 ) uResult |= KBD_ALT;
   if( GetKeyState( VK_CONTROL ) & 0x8000 ) uResult |= KBD_CTRL;
   if( GetKeyState( VK_SHIFT ) & 0x8000 ) uResult |= KBD_SHIFT;

   return uResult;
}

I use it in all sorts of places within responses to WM_CHAR and WM_KEYDOWN
and WM_SYSKEYDOWN.
