Look into PreTranslateMessage... i think this is the path you will want to follow

Hi

the function PreTranslateMessage is used by the class that received the message to translate the message before they are dispatched. This gives the opportunity to the class to trap the message as, when the function returns TRUE, the message is not dispatched.

Here is a sample code for a dialog box:

BOOL C....Dlg:reTranslateMessage(MSG* pMsg)
{

// Select Only WM_KEYDOWN Message

if ( pMsg->message == WM_KEYDOWN)
{
// Select ESC and Enter Key

if (( pMsg->wParam == VK_RETURN) || ( pMsg->wParam == VK_ESCAPE))
return TRUE;
}

return CDialog:reTranslateMessage(pMsg);
}

Hi guis, as I see this is about disable it not in an aplication but in the keyboard.
I think you should implement some interfaces like IShell* ant register them to run at startup. There exists posibility to hahdle system events. John Fill
