View 12 Repliesi'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+minitbut 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?

View 7 Repliesi am trying to build a Visual Basic program with an Access 2007 database in the back. I have another Access 2007 database with two tables stored in there. Each table has two columns, a UserID and Password column. This database will be used with a LoginForm so that if the user enters a normal login and password they will be taken to a specific form whereas if they enter an AdminID and password they will be taken to another form with different features. I managed to connect to the database and it works fine but i tried making the passwords and user names case sensitive for better security. I don't have a problem with this when i try only one of the tables, but when i try to implement the second table (to check if the login is an admin or a normal user)

View 3 RepliesI created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.
I have a login form with username and password authentication . It works fine. But I want to give option to remember login info option in the form.
