Hi,

I need to create login id's for new users,in vb.net web application.
given the user first name and last name.these will be entered in two textboxes.the user id will be in the format
<firstname>.<first letter of last name/first two letters of last name/...>

before creating,i need to connect to the database and check if the created id already exixts in the column of databse.if exixts,we take first two letters of last name and so on...

How do i do this??
