I am currently working with VB.net 2005. I am trying to create a login form and use a text file as a database to login. The part login form is fine but i can't connected to the text file. When i use my coding with a database such as access or mysql is work fine.
How do I create a Login Verification routine (Login Form) in vb.net . i have an windows application with login form contain user name , password , ok button and cancel button .
as this one:
Imports System.Data.OleDb Public Class LoginForm1 ' OK button
[Code].....
but i want to run my application from desktop and will get confirmation if the user name and password correct by checking them in MS Access Database in the server.
so the the application in the desktop and the tabel of user name and password in the server.
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.
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.
I followed below attached tutorial but I got this error: Cannot open database "mydb" requested by the login. The login failed. Login failed for user 'NAME OF COMPUTER FOR THE NETWORKUsername'. Second question: When I deploy my application which communicates with SQL server, should I put in the installation file SQL server? If I need to deploy and SQL server, I have to configure server, right? P.S.I use SQL 2005. I changed Authentication Mode of the SQL server to: SQL Server and Windows Authentication mode.
How can i avoid multiple log into the application at the same time from different locations? If one user is logged in and the other user uses the same ID and PW to log in then he/she will not able to log in.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
I am attempting to write an application for booking conference rooms, now this application needs to have a login box with the option to create a new user.

i am working on an application which uses login form, search and registration in VB.NET but let this topic focus on login first i am using MySQL database via MySQL.NET connector
here is what i have so far Private Sub btnLogIn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogIn.Click
this code is used for login by querying into the database....the logic is like this..it query accoding to the username text box and pass word text box...if there is indeed such rows in the table, then the bacadata.read, else something else happens...i have a few question :
1.is this the right way of login in by checking the row is available or not?
2.is there any enlightment and solution for the appropriate way to login system by using database other than the one teached by my lecturer?
I am using VB.NET 2008 and SQL Server 2005. Inside my DB I have a table with login username and password. I want to connect my Login form to get data from this Table and if the user account is valid then it will grant them access to another page.
Im working on a login form that connects to an SQL 2008 database. i have created records in the table for users who can login. i however want a code snippet that matches the username and password entered with the records in the database. i have a rough idea about it but
this is what i have:conn - the connection string to the database usercmd - object for executing sql commands userstring - the sql string object Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click Dim count As Integer
i want to make a login system using an sql database but i don't know how to create an sql database and don't know how to make this program, how to make a login system with a register button too using an sql database,and how to make the program
I wanted to make a Login that never use Database and able to create Username and Password.So far I know there is possible to do it but I dunno how because I saw a guy use NOTEPAD to store Username and Password. His program can register new username and password and login with new username and password. He is using VB + visual studio 2010 to create the program.
Im new to vb and mysqlHow can i make it where you type your username and password and it connects to my database hosted on my site and then if the user nameexists and password exisits it will login and if it doesn't it will get you a error message?
im trying to let users login to an application i created in vb.net using the user table of the application's database in mysql i heard that The usual way to do this is to have just one MySQL user called "[my_app_name]" with the relevant permissions. Then my application uses it's own user table to control access to the application, and the one MySQL user to access the database.
I am trying to build up a login form for my database. I have two fileds Username and password and two buttons Login and change password. I want the change password button to get enabled only if the user enters a default password set by me and the button should remain disabled otherwise.
ive made changes to my data stored in the database for a login i.e. ive changed the password that is stored in the database however for my application to continue the previous password still has to be used does anybody know why and how to change this, this also is the case for new entry's in the database i.e. new users. I also had an update button that also no longer works i think this is because of the same problem. I think the problem is that its saving the data changes from the update to the data set and not the database its self can this be changed?
