Please provide the compilable source code that we can compile, run and test. Programmers communicate better using source code, not 'common' languages.
To do it:
Copy all necessary files (including the database) to a new folder, except *.bak, *.exe, lib folder. Compress the folder and send the zip file to this forum.
If you're not willing to publicize your source code, you can write a demo example that showing that issue.
