Hello people...
I got a problem here..

I am using a vb 2005 and mySql as my database. I already created my project but it seems like when i edit my program.. it doesnt apply. What might be the problem? Is the vb.net application, MySql or the OS?

Thanks in advance.

Way more information needed...
What do you mean by edit your program? Are you entering or updating information?
It is most likely your code connecting to the database if the error is related to changing data.
Do you get any error messages?

are you saving ur changes by updating the database trough code?
