I've got some older MFC code I wrote that I'm "freshening up" a bit. I have the following code in a window class' OnChar() handler.

I really don't like using constants like 0x18. I'd like to make the code more readable. I know I can declare my own, but are there no Windows macros for these values? I couldn't find anything about this on the web.

// Check for clipboard commands
switch (nChar)
{
    case 0x18: // Ctrl+X - Cut
        OnEditCut();
        break;
    case 0x03: // Ctrl+C - Copy
        OnEditCopy();
        break;
    case 0x16: // Ctrl+V - Paste
        OnEditPaste();
        break;
}
