Hi

The problem area is just a small function. All I want to do is just adding a parameter. It has nothing to do with string length. So I opened the form with notepad, do whatever I want in there. So far the lines are still there. I'll try not to touch that part of the code to prevent any unpreditable behavior.

But I have also encounter the same problem Vince has, which has to do with string length. Everytime I reload the project, that particular part of string concatenation is missing! And I always have to retype the codes again. So I rearranged the code and have no problem so far. And again, I'll try not to touch this part of the code either. You never know what unpreditable behaviour you have.

I also once had problems where there wasn't anything wrong with my code but VB had compilation error. But there wasn't any error if I run it on another PC.
