VS 2008 Check If Username In Sql?
Jun 13, 2009
im using VS08 and i got this script to check if username is in database if not insert it which works halfway lol which it says the username is being used even when there is no username in database.. here is the script
Call ConnectDatabase()
Dim myAdapter As New MySqlDataAdapter
Dim query As String
[code]....
and is there a way i can create a label on login form and when the user creates a username it will go to the login form and put up on the label "you have created a username" or something like that?

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

I have an ASP.NET application on our company's intranet. And a funky security requirement.
I need to check to see if a given username is in a certain role. I cannot use
Page.User.IsInRole("MyDomainMyGroup")
because
Page.User.Identity.Name
Returns an empty string. Because of some lovely specifications for this program, I have to keep anonymous access enabled in IIS. Seems to rule out any page.user.identity stuff.
So I did find a way to (at least) get the current user (from System.Environment.UserName), but I need to bounce it against the domain group to see if they're in it. Or, better yet, get a list of users within a given domain so I can check myself. Something like...
Dim UserName as String
UserName = System.Environment.UserName
If User(UserName).IsInRole("MyDomainMyGroup") Then
[Code]....

I am working on a code for a chat client/server and I have it all working, I can connect and chat locally and global. The problem I am having is that when someone just hits the X in the corner to exit it crashes my server as well as the fact that if someone wants to they can make their username the same as someone elses.

I've created a new datasource dtsLogin containing an ID, username and password. my problem is how can you check if the username & password typed in the textbox are the same as the one on the Access database? I thought maybe using a rowfilter but I'm not that good in ADO.net.

My intent is to have the code - on a button.click event - check the Username and Password fields and return an error depending on which is wrong. Or if both are wrong, return a different error message. I've set the username as parts and the password as parts (still learning how to use external authentication). [Code]

I'm trying to select a 'Username' value from a table called 'tblUsers' where the 'UserID' is 1 and assign it to the 'Text' property of a field. The SQL command is fine, but I don't know how to assign the value to the file. I've changed the SQL command to select the value I want. I just don't know how to assign it to a field:

I'm making a tool to a game and I need to fill in my username and password and then click on a button.
Here is the html
Username:

<td><input class="text" type="text" name="e27a7f6" value="" maxlength="15" /> <span class="error"> </span></td>
Password:
HTML
td><input class="text" type="password" name="e8ca7cd" value="" maxlength="20" /> <span class="error"> </span></td>
Login button:
HTML
<input type="image" value="login" name="s1"onclick="xy();" id="btn_login" class="dynamic_img" src="img/x.gif" alt="login knapp"/>
In Vb 6.0 the code was
Webbrower.Document.All("s1").Click
for the login button
....
Form2.Wb.Document.All("e27a7f6").SetAttribute("text", User)
....
I get a "NullReferenceException was unhandled" error.

I've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.
