ElseIf Textbox2.Text = Nothing Then
MessageBox.Show("Please enter your password")

basically i want to create a login to my program which uses the same username and password as windows login.I already know how to retrieve username and auto place it in the username box using
TextBox1.Text = Environment.UserName.ToString
i wondered is there an easy way to only allow access if the password matches up to their logon? i dont know about setting up databases but i dont think this option would work because each member of staff can personally choose their password.

i'm trying to make a login form connected to an sql server database. my data base has records like this:
fname - lname - minit
each name in a separate column, and i wanted to use the name as the login username, so in the dataset designer i made a new column and concatenated the names together like this: lname+fname+minit but at Dim dr As SqlDataReader = cmd.ExecuteReader i get this error:
"Invalid column name 'username'. Invalid column name 'username'."
i'm asuming that's because username doesn't actually exists in the database, only in the dataset.is there a way to get that to work with out the username column actually existing in the database?

I've created a new datasource dtsLogin containing an ID, username and password. my problem is how can you check if the username & password typed in the textbox are the same as the one on the Access database? I thought maybe using a rowfilter but I'm not that good in ADO.net.

I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

create a vb 2008 code that requires a user to log in. His username and password are stored in an ms access table. Everytime he logs in, that table is searched for the corresponding username and password; if successful, form1 is opened; if not, the program displays a username and password mismatch error message and allows the user up to 3 attempts before it closes the program.

what I have mainform with two labels Text is User and Pass. I have a button on the main form called Set that opens the login form. There I have two textboxes, UserName and PassWord. and two buttons Save and Load. When you type the user names & password into the textboxes, and click save, if file exists you will be prompted to replace existing file. I also have added code to display the user name and password in the labels on the main form. Once you save the file I can now close the project and reopen the project click the set button to bring up the login form, and click load. Now the file is read and the saved username and password text is displayed in the proper textboxes on the login form.I also added the code to display the textboxes in the labels on the main form. Now I'm trying to use the lable text to fill the username and password textboxes on a login form of a website. I've tinkered with several different codes to do this but everything I have done has failed. I really need help getting started in the right direction. Here is my main form code and the code I'm working with.
Private Sub lblPass_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
Private Sub btnGet_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGet.Click
