Create A Secure Login Page Using VS 2010/ASP.Net?

Apr 5, 2011

I would like to create a secure login page for a pre-defined set of users (so no creating username/passwords by the users themselves). I've looked up a few sites and they all seem to suggest using Microsoft's Membership or something. I am not very sure as to why that's used, but all you need to know is that I will be creating the login details. I just need to make the login secure, ie, no duplicate logins, no logins from different browsers and cookies and sessions and encryption and all that. Any one have the code/links to where I can get all this?

Creating Script For Secure Website Login

Nov 3, 2009

I am trying to create a script that can login to a secure (HTTPS) website using credentials I supply then use MS' bitsadmin tool to download a report from the website. Once I automate this, I can then automate some processes of handling that report. So I am taking this step by step and trying to focus on getting the autologin portion to work before taking any other steps. The website I am logging into is not your typical site, it requires 3 fields 1) Organization 2) User Name 3) Password. See attached image as a reference. Also I have attached a text file with the source code of the relevant portion of the website login page.

So I hunted around and built a script off of a couple others I found and I am very close. See below for my script. The main problem I think I am running into is the stupid security alert popup I get from IE. I have no idea how to use the "sendkey" function on this popup to send "y". If I did, I think the script would work. When I run the script IE opens up and the security alert popup appears. I can wait as long as I want, but the popup doesn't go anywhere and IE just seems to sit there. [Code]

Download Secure Page Using System.Net.WebClient?

Mar 13, 2009

Dim wc As New System.Net.WebClientGamerTag.Replace(" ", "+")wc.Credentials = New System.Net.NetworkCredential(Email, Password, "http://live.xbox.com/en-US/profile/profile.aspx?GamerTag=" & GamerTag)Dim fx As New System.IO.StreamReader(wc.OpenRead("http://live.xbox.com/en-US/profile/profile.aspx?GamerTag=Dark Slipstream" & GamerTag))Dim str As String = fx.ReadToEndfx.Close()

The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.

Making A Login Screen

Apr 20, 2012

I am trying to make it so when a user logs in the code can tell, if they are a user or not, if they are a user, then if they are a teacher or not. I have SQL in there to identify if the person is a user or not, but it won't bring up an error message if they aren't. And if both the users logging in are not teachers they are still able to view a screen they are not meant to.

Making A Console Application With A Login?

Mar 26, 2012

I'm making a console application with a login. The system I have now is extremely basic and very redundant. I would like the password to be masked as you type it in "*****" for example and If possible I would like to encrypt the password with md5. Can someone let me know how to/give me the code to do it.

This is my current login system:

Sub LogIn()
'A log in system to prevent unwanted users from acsessing the system

If username = "sian" Then

Creating A Login Screen Without Making Use Of A DataBase?

Mar 25, 2011

I need to create a login page as part of an assignment. Problem is, I don't have access and I'm not sure which other programs can be used as alternatives. I am hoping that it's possible to create the login screen using only a If...Then...Else Statement. If it is possible, I'm probably going about it the wrong way, as it skips the first two conditions and goes straight to the 'Else'.

Making Airline Reservations System?

Mar 11, 2012

I'm doing an airline reservation system program, but I can't wrap my head around it. I can't even come up with psuedocode. The airplane has 10 seats. The user needs to choose first class(seats 1-5) or economy(seats 6-10), and I need to make sure that no seat is sold to more than one person. And if there are no more seat in the selected class I need to display a message box "there are no more seats in the selected class. Would you like to switch classes?" else display message " next flight leaves in three hours".

I have more code now!:

Public Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Dim firstClass() As Integer = {1, 2, 3, 4, 5}
Dim economyClass() As Integer = {6, 7, 8, 9, 10}
