Help regarding Facebook Connect...! - facebook

I have completed the facebook connect process. I need to address the following issues....
If a user has authorised my application: then on pressing F5, he must automatically be signed in...
If the user logs out of my site, he must log out of faceboook as well, and then display a dialog message.
Please help

You could try to redirect the user to Facebook's logout page. I doubt it works but it might be the only possibility.
Why do you want to log the user out of Facebook anyway? As a user I'd be pretty pissed about that, but then again I don't know what kind of app this is so it might make sense in some custom Facebook interface or something.

You could do something like
logout
However, it's rather user-hostile: unless I (the user) have asked you to do that, why the **** are you logging me out of Facebook?

I want users to always see the Facebook pop-up on login

I have a site that logs in using Facebook. The first time a user logs in, they get a pop up from Facebook explaining all the parts of the user FB profile my site will have access to. After accepting once, though, they don't get this pop-up on subsequent visits. Is there a way I can ensure that the user always sees this popup?
Update:
I'm trying to find a way to do this during development, so that I can see the list every time. I don't really need this in production.
they see it because it's the standard OAuth workflow to accept the terms of the application they are authorizing through facebook. Once the auth is complete, they are sent directly through, no reason to ask them for auth over and over.
EDIT:
Based on your update, the list is visible through your application settings in Facebook. you can use facebook's api to get these users.
You can build a "Fake Login" - there you can show your terms again. So your clients got a better feeling. ;-)

ASP Classic: twitter and facebook autoposting without signing in

In work I got a task (we MUST work with ASP Classic by the way): when user posts a blog, a link to that blog should be posted automatically on user's facebook timeline and in his twitter. I made everything working, but there is one problem: user needs to be signed in to post. I've made the cheking if he's logged in, and if not he must log in.
But I need to avoid the logging-in step and make it automatic (by sending user's username and password as part of the data sent to twitter/facebook or something like that), but I can't figure out how to do that or if it's even possible at all.
Any ideas? Would greatly appreciate any help.
P.S.: for the twitter part I used http://scottdesapio.com/VBScriptOAuth/
for the facebook part I used a combination of: http://snipplr.com/view/61108/facebook-app-login--authorization-entirely-clientside/
Everything works, but is it possible to automatize the user's sign-in part?
Finally I managed to make the both things automated...
The problem with Twitter was that I didn't store request token in session, that's why I got "Could not authenticate you" error.
Can't remember what I did wrong with Facebook (some co-workers helped me out), but I guess I didn't make proper http requests...
So the answer is: yes, it is possible to automatically post to Twitter and Facebook without user sign in.
If I am not wrong then your logged in user in facebook for current browser is not authorize for your app.
I think you should try googling about "How to authorize users into app". OR
If you don't mind I am giving you the direct URL to go to that setting page for your app:
https://developers.facebook.com/apps and then go to your app then after from left side bar go to roles and then after click on test user tab from top of page and then click on add button it will opne one pop-up to add a user.
In app you have to add test user for testing purpose and have to login for that added test user, so added user will be authorize for that app and you will be able to test.
Thank you...

facebook logout without sdk

How can I log out user from facebook without authorizing him myself?
I have a public IPad which people come to, authorize in my application and do stuff.
One of the links leads to m.facebook.com/sharer.php?u=..
When the user presses it, he is redirected to facebook, which asks for his login/pass and makes the share.
Later then the user press Logout on my site
I need to log out him from facebook some way,
so the next user who will use the ipad and press share will post to his wall and not to the first user's .
Same happens when i provide the iframe version of the Like button.
The first user logs in to facebook, makes the like, logs out of my web site,
and the next user see the like button pressed.
Thanks in advance ;)
I've just done some work with facebook recently on one of my projects and I used to visit a url to log them out it was something like
http://www.facebook.com/logout.php?redirect=your_url
It may not exactly be that as its off the top off my head but after visiting that the user got redirected to my site again logged out of facebook.
You may also have to provide a token.
Hope this helps!

Facebook C# SDK. How to automatic login user if they already login from facebook.com?

Here's the problem,
I want to have the user auto login to my MVC3 website if they already login from facebook.com.
If they are not login from facebook.com, I will just simply show a login button and they can login by clicking on it as usual.
I cant seem to find a way to detect whether user had login from facebook.com unless I force the application to direct go into LoginUrl of Facebook, which is not good for user who was not logged in as this will prompt them a page where they have to login. I still want to allow guest access without facebook account.
Any idea? Thanks a million.
EDIT:
Sorry I forgot to mentioned the situation only apply to user who approve to use my app. Once they approve to use my app, I'll be able to detect their facebook login status.
The answer is: You can't. At least not without violating the facebook TOS and probably at least one or two laws.
EDIT: Your original question sounded like you wanted to try and hijack the facebook user session. What you are talking about here in the comments requires you to use facebook connect / facebook for websites.

Authenticate to Facebook without Clicking Facebook Connect Button

I have added Facebook Connect to my application via the JavaScript SDK. I'm using Spring Security (this is a grails app) and I have added code that when someone clicks the FB Connection button to login, I manually authenticate them against their user account and everything gets wired up appropriately. I have 2 questions:
When a user first logs in with FB and I don't have an account for them, I create an account for them with their FB info, generate a random password, and use their email for their login name. If the user then uses the regular login form instead of the FB button to sign in, how do I sign them in to FB as well?
Every time the user clicks the FB Connect button, the popup window shows up. If they are already authenticated, it just goes away and then my web site redirects correctly. How do I keep the popup window from showing up in this case?
Thanks
To you first question, the user might be connect on Facebook when landing on your page after registration. So you can rely on the Javascript SDK to help you out.
See here: http://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus
To your second question, I think you can't, except you might get a work around if you use the Javascript SDK mentioned for the first question!
This is how I did it for moviezine.se and it works just fine, but it might be a little irritating to be logged in without asking for it when you come back a few days later. Then there is the use case of the logout: if you are automatically logged in, are you automatically logged out too; and if not, what if your Facebook session is replaced by your girlfriend's one who is also a user on your site! :)
