@Poster, you need to pick up a book on programming. I suspect that is what is needed here. Then you can come back with a question we are better able to help with. Also, use GOOGLE . . .it is a good friend of your.s

Goal: write a simple login form (I'm assuming you don't have the form yet.

How would you achieve this "manually" (pseudo code)?

1) present a form to a user
a) add a form
b) add controls (a username field, a password field, and a submit button. Add a clear button if the spirit leads you)
For good practice, rename controls to make sense to you. E.g, btnflyingboat for a button that lets you get to your flying boat

2) add event handlers for each control that you need to trigger an action. These are the "messenger on demand"s
I'm guessing this is only going to be the submit button unless you want to have validators tied to every control. Unnecessary processing in my opinion.

3) remember to include error messages so people know what's going on when their attempt at log in fails.

The above is what you'll do irrespective of the language. Do you want log in over a server? If so, you need more than vb.net.

For vb.net, I'll go with gadoonline's. I'll also add "option explicit" at the very top to prevent mixing up variables. Especially if you are new to vb.net or writing several lines of code.

I'll tweak as follows (note that this goes in the submit button's click event...
a) you can get to the code editor by double clicking on the controls on the form)

Dim strUname as string
Dim strPword as string

StrUname = me.txtUname.text 'this assumes that the username text field was named txtunam
strPword = .... 'complete as above

If (struname = (a username) and (stpword = ...) then
Do what you want to happen on successful log in
Else
Display error or whatever you want)
End if

If, on the other hand, you want to pass credentials from a db or table, you want to:
1) pull all of the user name and password combo and loop through, or
2) query the table for the record set with the combo entered

2 makes more sense especially for a large database.

Let's know how it goes. Good Luck!

this is not fair... This guy should go and work hard. Then come and tell us the errors he encountered. Let us stop spoiling young programmers

Thats very easy. I now use a database to store all my login-IDs to allow for different users ttho.
