so? Add them. They have constants just like the enter key does. Note that it will be very hard to determine if the ctrl or shift key is actually still pressed when you check another letter with this program. Your only option to make this 100% is to hook the keyboard. A side effect of a keyboard hook is that you don't need to call the code in a timer. It will be called automatically with each keypress.

you can easily make this into a keylogger by adding the code in the KeybCallback function. most virtual keys are equal to ascii codes so the coding is pretty straightforward.
