StringReplace is eating my string?

[jwurmz]

I'm opening a file (w/ flag 16), reading the contents of a file as binary string, converting the binary string (with BinaryToString) to a 'regular' string, and trying to StringReplace a potion of it based on a start value (portion length = replacement string length, start value = predetermined offset in the file).

The problem is StringReplace is returning 1 (along with 'eating' my source string) and I'm not exactly sure why. Some of the characters in the converted 'regular string' are sometimes unprintable characters; they may be any value 0-255.

I guess my question is -- does StringReplace return error = 1 if it encounters any unprintable characters in the source string?

Can you show a simplified code failing to work as you expect, along if possible with an example of the contents of the offending file?

Actually, I found a workaround by using a couple extra StringMid steps instead -- works exactly as I expect it to now. Thank you

A lot of functions choke on Null characters. It would be easier to just work with the binary.

I tried working with it in binary form and all of the sudden other areas of my program started acting funny.

If you're still wanting to look at it for the sake of curiosity, I can supply the data files and the source but the logic for StringReplace has been completely removed from my code so you would have to build that part back in yourself. The problem has been sidestepped, so it's up to you.

Thanks for all your help over the last week jchd, it's very much appreciated!
