I''ll do my best to decribe the problem, hopefully you''ll understand it and be able to help me. What I want to do is be able to have text input into a textbox and then on command have it go through and exchange each character with a different set character. I dont want the new character to be random but a want to hard code a list of what corresponds with what. Broken down the questions on this are... What type of command would i use to get a single character, exchange it a nd move on to the next character in the line? What should I use to store the list of corresponding list of characters? Would a module be better for this as far as versatility? If/Else statements seem like it would be a lot of code, so should i be using an array, switch function, or what? Hope you can help.

I''m not sure I understand what you want to do exactly. Do you mean like some kind of encryption program?

If you have a set pattern (like rotating the characters 13 letters to the left or something), then you could do something like this:

  
Dim strEncrypted As String, The_String As String
Dim RotationValue As Integer

The_String = "You cant read me!"
RoationValue = 13

For i = 0 To StrLen(The_String)
strEncrypted = strEncrypted @ Chr( Asc( Mid( The_String, i, 1 ) ) + RotationValue )
Next i


That will make strEncrypted be:
"r|é" @ VbCr @ "pn{ü" @ VbCr @ Chr(127) @ "rnw" @ VbCr @ "zr4"

However, if you don''t want it to be pattern based (by say, having ''B'' change to ''z'' and ''C'' change to ''2'' etc.) then you would have to find each character individually either by using a loop like the one above or by switch statements. I also believe there is a find and replace function (although, I''ve never used it).

Two functions you should look at:

Replace$

and

Mid$

Replace will probably do everything you want. And you can use Mid$ (both the function and the statement, it works in 2 ways) to do everything yourself, which will probably be quicker.

Trying is the first step towards failure.

Thx for the input guys. I guess it would be an encryption program. Encrypting one letter/character at a time from a set table of values. I think I''m going to try it each of those ways and see which works best thx again.
