What are you trying to decode? Or do you mean encode?

It would be easier to shift the ascii code along one.
Use asc() to get the ascii number of the character
change the number
use chr$() to convert the number into a character.

see code.

make a preset algorithm of what character changes to what character. Once you have that you can write a function that reads each keystroke and converts, then displays, the encoded characters. Better yet, make your program have 2 modes - Encode/Decode. Have it read/write files, enc or dec the file text as a complete file, instead of char by char. So then you could type a long message to your buddy, run your program in ENCODE mode to encode the file - send your buddy the file, and he can run your program in DECODE mode to read the file. Make your KEY algorithm in a flexible way so you can alter the KEY whenever you like.

If I may ask, why are you doing this? Nothing sinister I hope.

This is the newbies room. Ok. How do i do the key catching? Or better yet, can you write me a few lines of code? What's an algorithm? How can you create choosing mode? I NEED LOTS OF HELP!

"algorithm" just computer-speak for a procedure for doing something.
You might think of it as a recipe!
there are ingredients:
i.e. media files
there are steps to follow:
the program. the computer follows the steps.


or perhaps its the name of music written by the former vice president of the United States!

Al Gore Rhythm....

seriously,

look in DB's help for Mid$() Left$() Right$() Len() these functions are used to work with strings.

What are strings? er white fuzzy stuff?
another computer term.... its for text... like the stuff you want to encrypt! look at this line of text, it is made of one letter after another... a string of letters. if you see functions that end in a $, chances are its for working with strings.
take an s and a t, squish it together and get $!

who thinks of these things???

hope this helps.

PS
computers are stupid. they just do what you tell them to.
