The question needs a bit more detail.

The simplest form of that would be to create a form with two text boxes and a login or cancel button.  The cancel button ends the program.  The login button checks the two text boxes against a database of users and passwords to verify the user can run the program.  

Then just create an instance of your main form and frm.show it.  me.close your login form and you are done.

The details about how and where you store your users and passwords though is up to you.  xml, access database, sql, etc.  And obviously storing them in plain text is not nearly as secure as say an MD5 hash.  But work on getting the plain jane app working first and worry about that kind of security later.

ok, got it.

Yes, I was totally lost. Now I know what I need to start with, at first.

I guess my confussion was on the trying to get an answer for the whole problem.

I`ll start by creating the form with the two textboxes, like you just said.

Thanks a lot.

In case I need further information, I wont hesitate into posting another question.

Thanks!

There is no standard solutions for the WinForms Applications. You should create your own login form with name and password and then check them in DB. Do you need to create this functionality ?

What I need is to  create a login form with name and password. The authorized names and respective passwords must valid data in a DB.

In fact, if you are using vb 2008 or 2010, there is a template of Login Form, when you add a form to the project, like this:
