VS 2008 Login System Using Database?
Mar 20, 2011
My login system used a database1.mdf and if the user is new to the program it will have a default login, if signed in with the default login then user will be promoted to a firstrun.vb screen which will allow the them to change username and password or else it will go to the mainmenu.Problem : I am unsure how to stop the firstrun form from appearing if the user as already changed the password or username, either 1. and what code to add to the form firstrun.vb if they would like to change it, meaning updating the database.mdf
Imports System.Data.SqlClient
Public Class Login
Dim cm As SqlConnection
[code]....

I've created a log in system using a database and query builder to return the correct values, however, once the users signed in I need to bring up the rest of their data from the same table in the database. How'd be the best way of going about this? I'm not sure whether the log in should be changed to use the primary key as well.

I wanted to create a Login System. I am using Visual Basic 2008 Express Edition, Microsoft Access 2007/2010 Beta.Ok this is my current code-the main problem I have is that I dont how to compare what the user puts into the textboxes and then check that against the data in my database. [code]When I run/debug the program and enter the correct username and password into the program it comes up with the MsgBox("Incorrect Login Details - Please try again.").The connection string for where the database is coming from is right, because I checked it..so must be something wrong with the SQL Coding I guess.

i'm trying to link the program i'm designing so that it creates an entry and can refer to the record for the numerous pieces of information that was saved to it. I'm not sure what method would be the best to achieve this but I'm a bit short on time to have this done as it is a school major work and this is one of the final steps but me and my partner are stuck and the teacher refuses to help, probabaly because he doesn't know.
In the register I need to allow the user to input a Username, Password, First & Last Name, Email, Address and a Phone Number On the login it will only require a Username and a Password.
I'm really sorry I have not given any personal coding etc. but we simply don't know where to start.

I have been requested to implement a login form into a friend's Visual Basic .NET application. He specifically requested that I should do this using LINQ to compare the input to a table in an Access database. I don't really know why he imposed these restrictions, but who am I to judge? However, the problem is I am not overly familiar with VB .NET, or LINQ.

I'm trying to make a login system on visual basic. I need it to be able to connect to an access database to find the usernames and passwords. I have coded it as follows:
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
'Purpose: Make a Connection to the database and fill a Dataset with the Account and AccountTrans records
'Create a memory cell to store the drive letter of the USB drive
[code].....
The problem with this is that it says in the error log that an expression is expected and 'cmd' is not declared. The last section of the SELECT statement seems to comment itself out. What can I do to fix this?

I 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.

Iam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.

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.
