SQL Connection in domain names

Hi all, Do u know how to connect sql server in vb.net using domain login? That means when user log into the windows, then he use e application, he is able to do e data entry, viewing... etc, by recongising his domain login. He need not go into a password login.

You need to make sure the user is set up in SQL Server as a Windows User type login, then you can just create your Connection String in VB without the UserID and pass, and using integrated security.

Do u have any sample codes for the sql connection?

VB Code:

data source=SqlServerNameHere;initial catalog=DBNameHere;integrated security=SSPI;persist security info=False;packet size=4096
