GetKeyNameText without keyboard input but with saved datas

How can I use the GetKeyNameText to display a list of saved keyboard shortcuts ?

Saved datas is (for each keyboard shortcut) :

     VirtualKeyCode
     Alt key pressed or not
     Control key pressed or not
     Short key pressed or not

The problem is that GetKeyNameText gets a scancode in input (scancode is retrieved with MapVirtualKey(VIRTUALKEYCODE, 0)
but not the state of the 3 other keys (Alt, Control or Shift).

For example (AZERTY keyboard) :

 for the "A" key I will always get "A" instead of "A" (shift key is not pressed) or "a" (shift key is pressed)

 for the "&" key I will always get "1" instead of "&" (shift key is not pressed) or "1" (shift key is pressed)

Here its how to trap if CTRL / ALT / SHIFT is pressed along with other key...

just perform binary AND with scancode returned with MapVirtualKey with FCONTROL for CTRL key, with FALT for ALT key and FSHIFT for Shift key..

e.g.

int nScanCode = MapVirtualKEy(....);

if(nScanCode & FCONTROL ) // combination of key and CONTROL is pressed

if(nScanCode & FALT) // combination of key and ALT is pressed

if(nScanCode & FSHIFT ) // combination of key and SHIFT is pressed

In this way you can detect if key combination with CTRL/ALT/SHIFT is performed and if you want it in text form you may append appropriate text in text buffer

The nScanCode returned by MapVirtualKey can not be used with FALT, ...

These masks can only be used for the fVirt member of the structure ACCEL

The scancode is the same if you press the shift key or not.

NOTE : FCONTROL , FALT and FSHIFT all are already defined by your common header files just use them.

bit mistake ..

change that as follows :

its not scancode returned by MapVirtualKey but its your virtual code only...preform AND with your virtual code directly

e.g if nVirtCode is your virtual code which you pass to MapVirtualKey then

if(nVirtCode & FCONTROL ) // combination of key and CONTROL is pressed

if(nVirtCode & FALT) // combination of key and ALT is pressed

if(nVirtCode & FSHIFT ) // combination of key and SHIFT is pressed

try this :

e.g

 CString buf;
 nScanCode = MapVirtualKey(nVirtKey, 0) ;
 nScanCode <<= 16;
 nScanCode++;
 GetKeyNameText(nScanCode,buf,20);

 if( nVirtKey & FCONTROL)
  buf +="+CONTROL";

if( nVirtKey & FALT)
  buf +="+ALT";

if( nVirtKey & FSHIFT)
  buf +="+SHIFT";

MessageBox(buf);

Otherwise Simple solution is to : Use GetKeyStatus() function to retrieve if special keys CTRL,ALT,SHIFT are  DOWN , UP or toggled

look here :http://www.ddj.com/dept/windows/184416874 <=== refer CKeyEdit::ConvertKeyToString() and CKeyEdit::ConvertSpecialKeysToAttrib() functions.
