c sharp windows form

I suggest you to maintain an additional column in Database where user information is saved. Save the location of Last form opened by user when He clicks LogOut or exit button. 

Then get the form location and open on successful login attempt, store in a Object type of Form called MyForm or any other name. Then open as just below.

Ex.

Application.Run(new MyForm());

I am not able to provide you code because I do not have PC with VS installed these days. I would recommend you to read below thread.

HI Sharan,


Can you please clarify? You want to link a windows form to user on their login basis. 

Means do you want to maintain session to open last opened form for user. Please clarify.
