Hello
I have a windows application that works with a .mdf database. This application runs offline.
I installed it on my client's system with sqlexpress database. Now the problem is after working for few days it don't allow to login into the application. I have attached a screen shot of the error also.
I know its a database connection problem. But database is on local machine and its works fine. But after few days automatically stop connecting.
Could please suggest me some reasons for this problem
Thank you
