I have a form in my application, and when I logIn, I make a query to SELECT the username, the password and the level of username.
"SELECT username, password, level FROM TLogin WHERE [username] = @username and [password] = @password and [level] = @level"
So, when I logIn, I go to a form called "Options", I would like to know how to only show the information about the user that I've loggedIn ?
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

In my vb.net windows app, which runs on windows server 2003, i will like to return all the users who are logged into the server. How to do that?
View 3 RepliesI need to convert a large VB6 app to vb.net which does a lot of database work and produces a Crystal Report. The initial form is simple a login form which validates the user. I am trying to use a datareader to retrieve the user's login info but it won't compile on the statement where I'm trying to get the Connection String from the app.config file. It complains that the ConfigurationManager is not declared on the dim statement. Where and how do I declare the ConfigurationManager? I thought it was just pointing to the app.config file but apparently that is not correct. [Code]

so I've started using the Webbrowser control, and I've got it doing most of what I want (a button takes them straight to the correct page on the correct site, it's filling in text boxes, will fill out more once I get to that step).However when I go to the particular secure site my users are supposed to login to, it brings up what I assume is a windows domain login prompt with a check box to save the userid/password.
Saving the password is not allowed for this secure site, and when I use system.webclient to get the first page so I can use my own windows for getting the login info, it doesn't carry over the authentication info to the webbrowser if I let it go back to using the web browser's default navigation methods, nor does it load the images or the page properly.I was thinking I needed to set the webbrowser's credentials, but I can't find anything exposed to make changes to or override if I try to inherit.
i'm behind a webproxy, and the site itself requires login. I've figured out in code how to pull back secure pages that require you to be logged in, but when I pass that html up to the webbrowser it doesn't know how to access or load the images or other things that the html instructs it to do.
I wrote this code to the load event of the form which contain the report viewer , i connected it to the dataset but it is asking for login info whenever i am opening the report..
View 2 RepliesI have just added a login form to my main form which just has a username textbox and a password textbox. What i basically want a user to be able to do is enter their username and password into these fields and then for the form to store the values there.
So if they enter their username and password, and then click OK on the login form, if they were to open up the login form their details would still be there?I want to be able to call on these values else where? How do i store the info in the username and password fields? And if they then closed the form and opened it up again would it still remember what username and password had been entered?
Hi, I've created a login screen for my application and defined the username and password using the following code
If UsenameBox.Text = "username" and PasswordBox.Text = "password" Then
Me.Hide()
Main.Show()
It works great however, I need the user to be able to set their own password using a registration form with the details being stored in a xml file. There are no security concerns with the password being stored in a text file as it's a mock login screen.
I am trying to have my application use our email servers to send out an email when a certain action is taken. What I want it to do is use the username and login that the user is logged into the domain as for their email username and login. How can I get access to the users domain login and password? For instance, if I log into the computer, I want the application to use my windows login and password as the email username and password, since they are the same. This way I don't have to ask for it. I tried importing System.DirectoryServices and it once I type in Imports System. it does not have directoryservices as an option.

And in this code, if there is a username/password that was matched with in the database, it'd place it on the dbUsername/dbPassword variables and compare it with the ones that were inputted by the user.What if I wanted to know if there is none of that username (like, username doesn't exist from the database)?

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'."
