It seems that the behavior for the shift key is that when the shift key is pressed with another key, dbScanCode () returns the scan code of the key that is NOT the shift key. So if I was pressing shift+a the scancode would be 30. This works with the right shift key as near as I can tell all the time, but when using the LEFT shift key and pressing any of the keys ",./" which in uppercase is "<>?" the scancode returned is the scancode of the left shift key. This is screwing up my GUI code!!! Has anyone else had the same problem?

Is this for text editing? If so, don't use dbScanCode(), use dbGetEntry(). This will get any key combinations that are pressed. I use it in my GUI. There are a few keys that don't work using this, such as [DEL], [BACKSPACE], [INSERT] and [ENTER], but you can make an exception for those.

The fastest code is the code never written.

It is for text editing, but rather than use dbEntry$ I made a character map:



I just liked this approach better. It works really well, just not for those three keys if holding left shift. Again, works fine with right shift, but not with left shift...

Scan codes are returned in priority order so your left shift is a higher priority than those 3 keys. As a matter of fact, my entire bottom row of keys is trumped by my left shift as well as some other keys. Afraid you'll need to go with Hawkblood's method. Also, dbKeyState will see multiple keys being pressed simultaneously. I always use it to get the state of the arrow keys so I can do things like press up and right at the same time without any conflicts. Might be worth a look. Good luck.
