Keyboard Scan Codes

[Halifax]

Im using KeyRight, Left, Up, and Down right now. however, i have searched the internet and this site for the scan codes for other keys like esc etc but i cant get a straight answer.
right now i have this
KeyRight$ = chr$(77) + "P"
(this is quoted from memory, which means its wrong)
so how would i do esc?
KeyEsc$ = chr$(1) '?? that is what qbasic says ESC is... but it doesnt work

[Mitth'raw'nuruodo]

inkey$ returns chr$(27) for esc

[Z!re]

If inkey$ returns a two byte value, it is: chr(null)+chr(scancode)

Otherwise it's chr(asciicode)


Both scancodes and ascii codes can be found in the qb help.

Index->Character Scancodes
Index->Character ASCII Values
(or something)

[Mitth'raw'nuruodo]

Ya, something like that.
Z!re, I always wanted to ask this:
1. Whats with the first 30 ASCII codes, they don't work.
2. Whats with the Scancodes, they don't work.

[{Nathan}]

to find a key, just type it while running this program.

Code: Select all

do
a$ = inkey
print src(a$)
loop

then you cana just

Code: Select all

 run this and find you chr value. src is the revverse of char, btw.

^_^, um nathan? you need:

LOCATE 1, 1: PRINT a$

Other wise it will scroll,

Here, this tut has a list of all the keyboard input codes that you'll probaly ever need: Basic to Advance keyboard programming

[Mitth'raw'nuruodo]

Better yet:

Code: Select all

DO
 LOCATE 1, 1: PRINT INP(96)
LOOP

That is a better one then INKEY$
Not only do you have a set of numbers for every key on your keyboard (yes including Alt, Ctrl, Shift), But you have 2 sets for eaxh key. 1 set is when the key is pressed down, the other is after it has been released.
