i have a login form in a banking project.i set a userid and password for this login form and i did the code accordingly,it works good.In my form there are two fields namely:Userid and Password and a button named Login.
But i cant get any idea about what to do when the user wants to create their own userid and password?
I think i need to add a few more buttons to enable the user to create their own userid and password but i cant get the idea......i need some help.
Again,if i allow the user to create their own userid and password then anyone can use my project by creating a new account.........
Hence i am totally confused how to go with this.I need some urgent discussion so that i can get through this problem.

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.

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 the lines above to login by database. However, I really don't know why always give me the error: "Incorrect fields". I am 120% sure that all the fields of the table are right, including the text that I put into my textboxs. I have already add a user into the database. I can make login in PHP but in VB.NET I just can't.
Try
Dim MySQLConnection As New MySqlConnection("server=localhost; user id=root; password=; database=DB")
Dim MySQLQuery As String = "SELECT * FROM TableLogin WHERE Username = @username AND Password = @password"
[CODE]...
I already tried to show the data of the database into a Datagridview and it works fine, it displays to me all the rows that I had add in the database.
