How To Use Facebook Authentication With Asp.net Login Control
Apr 17, 2012
I have been digging on facebook authentication for a week. I came across so many things such as facebook_connect, Facebook C# SDK from CodePlex and other ways to connect with facebook which are absolute now. Finally after reading url.. for many times, I did manage to have a login button and get user's information for facebook using the new and standard Graph API stuffs. There are in Javascript such as. [code]I can't remove all form authentication from the existing website. Facebook login should be value added feature to the website. Now the few bits I don't get is.How to authenticate the asp.net Form authentication when someone Login to the website using facebook Login.How do I pass all the value in the javascript to aspx.vb to connect to database and store the information.I understand I would need to create a new table in the database, probably called FacebookUsers. But I can't think a way that facebook authentication and asp.net Login control to work together. My website is in VB.net by the way.

The user must submit his username and password. After 3 unsucessful trials, the program must terminate. It is required that I use the for loop structure. I don't know if i'm making it right. Here's the code I've done :
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim c, d, f, g As String
Dim a As Integer

webbrowser1.document.GetElementById("email").SetAttribute("value", "my email")
webbrowser1.document.GetElementById("pass").setAttribute("value", "My password")
webbrowser1.document.GetElementById("I cannot find the ID for the login key..please help").invokemember("click")
Nothing happens?

I have a vbulletin forum and want my program users to be able to use their same usernames and passwords they do to login my vbulletin forum. My program is done except for the user authentication. I have searched and googled for weeks now, here is what I know:
� vbulletin 3.8.4 uses, md5(md5($password) . $salt)
� I know how to get the Salt and stored hash from the mysql "user" table.
� I know how to connect to my database without any issues.
I used this code I found here and just modified 3 lines so I could try to get it to work. The code works fine for md5 + salt but as you know I need it to do this: md5(md5($password) . $salt)
Imports System
Imports System.Security.Cryptography
Imports System.Text
Public Class Form1
[code]....
After I can do this I will be able to code my program to retrieve the users salt and compare the hash to the one stored in my mysql database.

I have used the code from the link below to create a basic login page in front of the Microsoft Live Single Sing On.[url] I managed to combine the two together(LiveSSO w/Forms Authentication) turning off the Integrated Authentication in IIS from the SSO setup.All works as expected if the user successfully authenticates with AD. THE PROBLEM that I am having is that when the user failes to authenticate it only returns: "Error authenticating user. Logon failure: unknown user name or bad password". This message appears also when the user is set to change the password at next logon. What I want it to do is to read the error code of exactly why it failed so I can setup a redirect to a password reset page (i.e. if error is "User flag is set to change pswd" etc.etc.)From the page linked above you can see the VB code of LdapAuthentication.vb which does the trick of authenticating the accounts or returning the error message if the login fails. The part that returns the "Error authenticating user. Logon failure: unknown user name or bad password." Is handled by this subroutine:
[code]...
That's what I have been trying to customize to see how it can return a specific code based on the user account AD flags, instead of the generic message

I'm trying to make an authentication before my visual basic 2008 project, a login window. You have to login using your vBulletin username & password.

So, I'd like a form that ask you to login using your username and password from my vBulletin forum, so you'd have to register before...

I have a WinForms app with SQL05 backend. It has a standard Login window where users are required to supply a username/password. This is validated using my own code and sprocs. Now one of my big clients has scared the bejezus out of me by saying, "Hey Chris, I want you to change your app in line with all our other IT systems so that users can use their common username and passwords with authentication against LDAP". :confused: Having had a moment to reflect, I have some questions (some very noob in nature!)
1. Is this requirement a big deal? :) Or straightforward to implement?
2. Does this mean that when user's double-click my app icon on the desktop, the authentication automagically happens without the need for a Login screen?
3. How on earth can I test this. My dev environment does not use AD, but I do have SBS2003
4. Can anyone point me to good resources about this on the web?

I am using webbrowser control to automatically navigate through facebook.Nothing malicious, just an experiment of sorts.Im working on a bot that that would extract the names of all friends on my friends page, open up those pages, extract their friends names, and repeat.The end result would be a chart of who knows who. A sort of 'six degrees of separation' experiment.I have everything automated up until getting to my friends page and I am having trouble extracting the urls from my friends page. [code] Now, I figure I can extract from <div class=fsl fwb fcb">, but Im confused as to how to go about doing this. On another thread, someone said it cant be done with webbrowser control, but im new automation.

I'm developing an VB.NET application which utilizes a webbrowser control. The browser control needs to navigate to a simple page which prompts the user for their user name and password. However, this prompt is not simply a web form, but it is a completely new dialog window. I need a way to automate filling in the username and password in this dialog by using locally stored credentials, so that there is no interruption in the webbrowser control's navigation. The only information that I have been able find so far that might be useful in solving this problem, involves using windows hooks in the user32.dll to intercept and negotiate with these windows at a low level.

I am using the asp.net login control with sql server integration. I don't see any references anywhere to being able to log the logins and disabling logins if too many bad passwords are attempted.
Is there a VB codebehind event that can be triggered if it's a bad username/password combo? Basically I had the idea of creating a table that logs the ip and time and whether or not the login was successful. From there I can disable the login control if a certain number of failed logins occur within a timeframe.
