     Nothing pushing the limits of VB, but when developing games/apps and using GetAsyncKeyState, do you ever go, "Uhmm, what the hell is left arrow again?!". here you are. run this app, press the key (or combo) and there it is! I think this is more of a useful tool than a coding extravaganza, so please vote/comment accordingly. You never know, while you're writing your 1st class game, you may even use this tool! :-)

Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net

Hi Kenneth,
I have improved the display, but I don't believe PSC has a way for me to get it to you ?
I expanded the labels width by 3, and moved them to the right be 3 (now 525)
I did similar with the height, except by 4 (now 345)
I changed backcolor of the form to white.
I removed the borders from the labels
I set their Font to 12 Arial Black regular (no bold is used)

Some small amendments to the code, in my next post

End If
If sDisp <> lblDisplay Then
lblDisplay = sDisp
