In my ASP.net MVC app, I'd like to log a user out of Facebook on their local browser so that when they click the authentication button, they're forced to enter their credentials, even if they were previously logged into Facebook. I'd like to also do this after they're done authenticating, too. The end goal being that users will be able to enter credentials for multiple Facebook accounts.So how can I log a user out of facebook programatically?
I'm writing applications on Facebook located on an external website ASP.NET C #. The application should check whether or not a person likes my Fan Page (page) on Facebook, and if he or she doesn’t like it needs to like it before using this application. How this can be done using the Graph API and ASPSnippets Facebook API.
I have tested the solution in the tutorial for getting users information from Login with Facebook (AspSnippet dll). My answer: is it possible to get also First name, Last Name?
actullay my requirement is i need send messages to facebook user accounts using my web application(Asp.net,C#.Net).i have Users's facebook id and there there facebook Keys.
I am tying to get the work information from a facebook user using Graph API
When I use the Graph API and get the User object, it contains work information, which is essentially a list of the work history. The list elements contain nodes of employer, location, description, etc...
The FQL return it as a JsonObject, how do i get the the value employer out of it. I am only interested in the last employer. I tried something below but could not get it working.
[Code]....
There is more information that says it return the "work_history" as an array
I'm using the TokenExchange_Url URL to receive the unique user OAuth token to make calls with.
This is working fine, because a) i receive the token back, and b) i can issue HTTP Get Requests to the Graph API (i.e UserDetails_Url) and it works fine.
But, i cannot Post to the User's wall using the Feed_Url.I'm pretty sure the issue is i haven't got the appropriate user permissions to post to a wall (i.e facebook-side setting).
Now, i realise i can use the fbPublish API method client-side to do this, but i want to do it server-side with the Graph API.
I wont bother showing my code which attempts the call to the Graph API to post to the user's wall, as its pretty straightforward (HttpWebRequest, set method to "POST', set content type/length, write bytes to Stream, etc).
I think the problem is i need the user to grant my aplpication "publish_stream" extended permissions.
The Facebook Graph API doco says to do this in your authorization request:
Am i using the wrong Token Exchange URL? Why is there two different URL's to seemingly get the same piece of information?
Yes - i have read the Facebook API doco (numerous times), and yes i have read other similar SO questions, but they all result in using the client-side API to publish to wall, i want to do it server side.
For the actual "Facebook Connect" button, i'm using the standard FBML:
When i click this (and not logged into Facebook), it pops up a window which the user can login. But it doesnt have the "Request Extended Permissions" dialog - shouldnt it? Or is that another popup i need to manually trigger?
So to sum up, here are my questions:
How do i grant extended permissions to publish to the user's wall?What is the correct URL for obtaining an OAuth token?Is there a definitive source for showing how to post to a user's wall using server-side Graph API calls?
sir i have a code for getting facebook logged in user details like email, profile image and name in aspx page but i want it getting done from code behind i.e (.cs) page.

I need to develop a login where user can login from his facebook account. When user login first time, an auth dialog should open from facebook asking to user for access permission and than it should move to one of my page where I can retrieve user email address and first name & last name through his facebook access token. How to achieve this?
In my facebook canvas applikation, i store the access token in session. (I use ASP.NET MVC)
But i want to store the access token in a database along with the facebook user id that i can save different access tokens for different facebook users accessing my application.
So when i query the facebook user id and if it doen't return any access token, i request permissions and get the access token for that user.
How do i access the Facebook UserID for the user accessing my canvas application before doing any authentification?
i have made a gridview which contains three fields, two textboxes and one combo box. ComboBox fetchs data from table(SQL) and when a combox box triggers, data related to combo must be added in two boxes. i did this throw another button, but i want this to be trigger directly when it clicks..

I'm trying to create a basic application, i created facebook application before but everything has been changed.
I looked every where to create a basic application, but now i'm getting mad because there isn't any working sample. Because of the changed links, facebook api changes, facebook wiki changes i couldn't find a working copy.
write a basic app that gets permission to write user name to screen in facebook developer toolkit asp.net. I looked computerbeacon.net, codeplex, and some other pages but i couldn't succeed.
Edit: I' m adding some screenshots and some codes, it will may be you to find my problem.
