how can i get a value from my database table and display in a textbox or in the label...

using c#(window application and web application)

kindly guide me

There's more than one way to do it, and there are questions that have to be answered first. What kind of database is it? Do you already have a connection? Are you running a stored procedure or an ad hoc query? Does the query need any input? Are you doing any other work? The process may need to be run as a transaction.

And more importantly, what have you tried already that didn't work?

this is wat i av done...
