Shouldn't this command return the text value of an ascii code?
Like chr$(16)="Q" but instead it prints a square in my screen

What am I doing wrong? Which command should I use to turn the ascii code 16 into the letter Q?
Take care

chr$(16) is NOT the letter "Q".
try this (It will tell you the real value for "q"):
do
in$=str$(asc(inkey$))
text 10,10,in$
loop

Hmmmmm you're right!!!!!

Then how can the Scancode() command detect the 'Q' key as 16??
Doesn't scancode work with ascii values?
I've been programming basic for years and thought I had put this part of basic programing behind me years ago but I'm getting rather confused here

I've been experencing some annoying problems with my computer.
For one my Ad-watcher detects that a program is trying to alter my registry every 30 seconds. Winamp continues playing its playlist even after I close it. Then, whenever I Ctrl+Alt+Del, my Task manager closes before I can even get there with my mouse pointer. But Norton doesn't detect any viruses with it's most recent virus defenitions.
Can whatever is causing my problems be altering ASCII codes ort whatever?

I don't think so. The values returned by scancode are not ascii.
Try running regedit and see if anything that shouldn't be is in the run folder. Maby that way you'll find out what's going on in your PC.

try the free virus scanner at www.grisoft.com . the problem with norton is alot of viruses target it because it's one of the most popular. could not be a virus, but it's worth a try, this is a great virus scanner and its free

Norton updated today its virus defenitions and after instaling it Norton detects W32.Spybot.worm. So thats maybe it. I don't know. Norton can't remove.

It doesn't differentiate between caps on and off so the codes returned by scancode were made to more easilly help the game maker.
Thanks for your help.

Scancode returns the code for the actual key that is pressed - regardless of the character on it.

I use a Spanish keyboard and if you use the Scancode value for the + key on a US or British keyboard in your program and say that the key to press is the + key, it wouldn't work on my keyboard as the + is on a different key.

The ASCII value however would work on all systems as only the + key would generate the ASCII value for + regardless of the key it was on.

The main benefits of Scancode is that it can be used with KeyState to detect when more than one key is pressed at the same time.
