I have a very generic login form created that allows a user to access a application. My problem is getting the log in form to close after the application form is loaded. I have described the specifics in the comments of the code. [code]
View 1 RepliesI am new to .NET and I have created a login page, with a user Id and password. In my webconfig, I put the following code in to deny users who are not authenticated.
<authentication mode="Forms">
<forms loginUrl="Login.aspx" timeout="10" protection="All" />
</authentication>
<authorization>
<deny users="?"></deny>
</authorization>
What I am trying to accomplish is that when a user enters the correct information, I would like to store information small information about the user in a cookie, say for example if there an admin, manager, user, etc...Here is the code that occurs when the user click the submit button. The problem is that the page doesn't redirect to the page after user enter correct information.
If txtPassword.Text.ToLower = "test" Then
'Create a cookie
Dim cookie As New HttpCookie("UserInfo")
'Cookie variables
cookie("User") = txtUser.Text

Ok i have a login window which connects to a MySQL database and authenticates the user. Works perfect, BUT
If rowsEffected > 0 Then
cnMySQL.Close()
LoginForm1.Close()
MainForm.Show()
Else
cnMySQL.Close()
MsgBox("Login Failed!")
End If
That's supposed to close the login form and open the main form if the query returned a positive match of the login information. The login works, closes the login form, opens the main form, than mysteriously exits the application. I'm guessing its something simple but i don't see it .. the main form has nothing in it besides some inputs and labels no subs at all and if i change the form which the program starts to to the main form it runs as designed.
I know usually if you start your program from a module and use Application.Run() you can keep the thread open, but this is all forms no background work so i didn't want to go that direction.P.S. i just removed LoginForm1.Close() and it logs me in fine and opens the main form fine and keeps the app running but the login form is still open.
When I run this code it give this error
""Mailbox unavailable. The server response was: 5.7.3 Requested action aborted; user not authenticated"".
The code:
Dim mail As New MailMessage()
Dim SmtpServer As New SmtpClient
SmtpServer.Credentials = New Net.NetworkCredential(TextBox1.Text, TextBox5.Text)
ProgressBar1.Value = 10
SmtpServer.Port = 587

View 2 RepliesI have made a windows forms application with a user login which queries a sql server database located on a central server. It currently has one sql server login which it connects to using a connection string in the app.config file. The user login is validated by querying a username table in sql server. I would like to make this a multi user application where after the user logs in, their credentials are stored and used by the the application to access the database with a sql server login. There will be 5-10 users.

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?
I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

View 2 Repliesi 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.

So what do I do? Neither of these work how I need them to.

View 10 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 been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using
