[beyrself]

Hi, i've created a application using microsoft visual studio 2005. I've publish the exe application using IIS. now is issue is. I need to restrict the login part. For example is A login to this website.. B cant login until A log off.
I'm using VB.net BTW!

Below is the code for my login page.
[code=vbnet]
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArg s) Handles OK.Click
If UsernameTextBox .Text = "admin" And PasswordTextBox .Text = "admin" Then
Form1.Show()

Else
MsgBox("Incorre ct password", vbExclamation, "Header")
UsernameTextBox .Text = ""
PasswordTextBox .Text = ""
End If
End Sub


[/code]
Can anyone help? THANKS

Hi,

First, I don't see the connection between you exe and IIS...Anyone else?

Second, it's difficult to check whether someone else is logged in if you check the username and password without using a variable. I think the only way to check this is some sort of boolean in a database that is checked whether the user is logged in. Of course, problem is that when someone logs out without going thru the procedure that unchecks the boolean, no one can login anymore.

I don't understand how IIS plays a part in your application either.....

Are you developing a Desktop application or ASP.NET application?
