Thanks Mark,
Actually, I need to check if there are characters outside of a list of valid characters. For example A-Z,a-z,0-9, are valid characters, how can I tell if an address has a value outside of these. I know I'm going to be using ASCII values, but what's the best way to search through the string? I use your method a lot myself when I know what I'm looking for. In this case it could be a rather large set of invalid characters, so I don't think it would be the best choice here. Thanks again.
Marcus.
