Similar to a calculator application wherein you would want to use a number
pad to type in the keys. Here in my application , which has a phone pad sort
of thing, I am using the number key pad to press the buttons. So basically
whenever i detect a key press, In the SetDTMFKey() function ,I change the
attributes of the button to indicate that the number that has been pressed .
And after that I post a message to another handler which does the actual
function of dialing the number. It performs the whole operation successfully.
but produces that sound that is annoying, when the key is pressed.

I did not understand your statement :"still passing them off to the program"

It looks like you are handling (doing something) with some of the keys, yet
still passing them off to the program. Is that what you intended? Does the
program do something with these special keys? Could be the program is just
complaining because you're trying to use a key that really doesn't do
anything.

I am using XP and this is how my function goes...

BOOL Console::PreTranslateMessage(MSG* pMsg)
{
// Prevent's escape from closing app
if(pMsg->message == WM_KEYDOWN && (pMsg->wParam==VK_ESCAPE ||
pMsg->wParam==VK_RETURN))
return TRUE ;

if (pMsg->message==WM_KEYDOWN)
{

switch(pMsg->wParam)
{

case VK_NUMPAD0:

if(DTMFKeyPressed==FALSE)
SetDTMFKey(0,TRUE);
break;

}
} /*End of KEYDOWN if statement*/
if (pMsg->message==WM_KEYUP)
{
switch(pMsg->wParam)
{

case VK_NUMPAD0:
SetDTMFKey(0,FALSE);
break;
}
} /*End of KEYUP if statement*/
return CDialog::PreTranslateMessage(pMsg);
}

Don't know if this would make a difference, but are you returning true or
false?

I've noticed a lot of dialogs and other things, as you put it, boink when
a
key is pressed (on Vista) that didn't on XP. Are you using Vista?

Hi,

I am trying to capture number pad key strokes for my windows
application
(written in MFC,VC++ 6.0) in the PretranslateMessage function of the
application and perform the appropriate action like changing a buttons
state.
It recongnizes the key pressed and performs the appropriate actions
successfully but produces a 'boink' sound whenever the key is pressed.
It
produces this sound only for the Alphabet , number keys and for the
number
pad keys except for the special keys like
Shift,Spacebar,Tab,Capslock,Insert
etc.

Could someone please tell me how to turn off that sound for the
particular
key press?I am desperately in need of help..

Thanks
