C++ 6.0 Barcode Scanner Program. Fix of a single bug.

I did a program myself that read a code from a barcode scanner then check a sql database and send a bit to open a gate if the barcode is correct. I have to say that my C++ skills are basics, I am mainly an Asp programmer, and I only slightly modified the example program given with the scanner with the code to do this simple task.

Now there is a single error that I can't fix in any way. It says "Structure Size Mismatch". I know which line gives the error, but I am not good enough to fix it. The problem is that the error comes up only randomly from once an hour to once every 2 days and the program stops working. There is probably some writing in the memory that shouldn't happen and there is no way to debug the program live as it is installed in a server (program doesnt work without the scanner), so you must be a very good C++ programmer to GUESS what the error is and fix it. Than I will upload it on the server and if it works for 5 days in a row I will pay. If not you will have to try again. So it is not a 1 day job but a 1 hour job, then waiting for a week, and than try some other solution for an hour again if it didn't work. If you are a C++ real guru you would only need an hour if not you might need 4 or more trials I don't know. But I want you to know that I will still pay the same amount.

Only if it is really necesary I will give out password of the server to give you full control. Bid saying if you need the password or not.

I am a programmer myself so I can tell you this could be Really easy money but ONLY for Some of you!

I will give you full help and support, also calling you in any country if needed.

Thank you

I need this to start by 1st of February. If you think you are the best and you are worth more than what I ask feel free to bid more for this.
