Hi all

Im automatically creating a folder with user information, but i have to make sure that there are no illegal characters and if there are i should replace it with a "0" but although it goes into my if statement it refuses to replace the invalid character.

here is the relevant code



Any idea's?
thanks.

String.replace does not alter the string you're passing to it; rather, it returns the result of the replacement operation. You want something like " fileName = fileName.replace(... "
