There has been a rise in the number of private homes being put up for auction by mortgagees or lenders. In the first two months of this year, there were five such properties, compared with only two in the same period last year. north park tender

Hello, I have opened the project in Visual Studio 2010. When running it it says call to webservice will fail UNLESS the silverlight project is launched from the web project that contains the webservice.

Hi Mrathi,

I'm sorry to disappoint you but this widget may not work as expected all the time. Due to limitations in the Twitter service the widget can't serve more than 100 tweets per hour. There isn't anything special that you have to do to place the widget in a non asp.net site. You just have to copy the HTML above on a page in your web site. You don't have to copy any files.

Hi,

I have downloaded your project and placed the ClientBin folder on my php website. Looks like it is not able to call the webservice to get the tweets. Can you please provide some information on how to use it in a non asp.net site?

By the way, thanks for the wonderful project.

That's not an option as you put the widget on your blog and you want visitors to read your timeline, not theirs.

RE: Silvester - A Silverlight Twitter Widget

Laurent — Thu, 14 May 2009 16:27:12 GMT

The widget should pop a dialog to enter credentials. Then you can save those in Isolated Storage for future reuse.

Now the problem is how would the users pass their password. Obviously, it is not safe to pass it as a parameter in InitParams because this way everyone can read it. We use a proxy service so there is no guarantee for the users that we won't store their password. I have to think about that.

From the Twitter API Wiki:

"The default rate limit for calls to the REST API is 100 requests per hour. The REST API does account- and IP-based rate limiting. Authenticated API calls are charged to the authenticating user's limit while unauthenticated API calls are deducted from the calling IP address' allotment."

Yep, you seems to be right. The rate limit is both account and IP-based so when I apply your fix every user will have his/her 100 API calls per hour. That would be enough for most of the blogs.

Thanks, Laurent!

Hello again,

Here is below what is needed to properly authenticate with Twitter so that your server IP does not quickly hit the 100 rate limit.

                WebRequest rq = HttpWebRequest.Create(timelineUri);
                // HttpWebRequest is a handy .NET class for doing HTTP requests. It has built-in support for HTTP basic
                // authentication via credentials. However, it doesn’t work the way I expected: supplying credentials
                // doesn’t send Authorization HTTP header with the request but only in response to server’s challenge.
                // It often breaks in real world, where servers might not issue a challenge and simply not authenticate a request.
                string up = userName + ":" + password;
                CredentialCache cache = new CredentialCache();
                cache.Add(new Uri(timelineUri), "Basic", new NetworkCredential(userName, password));
                rq.Credentials = cache;
                rq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(up)));
                HttpWebResponse res = rq.GetResponse() as HttpWebResponse;

Hi again Emil.

I believe your users are hitting the 100 requests per hour limit and this is why users are "complaining". I think the problem lies with authentication. I am currently working on this and I think I am close to understand what's going on... Will post again later.

RE: Silvester - A Silverlight Twitter Widget

emil — Tue, 12 May 2009 01:59:45 GMT

Hi, Laurent. I do not overcome this issue. I wrote to Twitter when I started to write the client but my request wasn't approved. Maybe I should try again.

RE: Silvester - A Silverlight Twitter Widget

Laurent — Tue, 12 May 2009 01:05:21 GMT

Hi,

I am curious to know how you have overcome the 100 requests per hour using a proxy service. Have you been whitelisted by Twitter? Are you caching requests? I'd really like to know...

Thanks

Vlasta — Sat, 07 Feb 2009 12:08:49 GMT

Hi, I can confirm that behavior. Only theframe and no feeds are being shown. It is the same on my own website, such as on the example shown here. It seems to be working randomly, because at first I'had seen feeds here, but they are not here anymore.

I dont know emil, twitter works fine at the time when this happens. And its happening intermittently number of times almost daily. It just shows the background box with links, no tweet text. Just now its happening again and I cant get the tweets on this page also even after refreshing. Is it to do with the hosting server? Please check.

RE: Silvester - A Silverlight Twitter Widget

emil — Tue, 06 Jan 2009 10:20:44 GMT

Hi vasudev,

I can see it is working now. I don't know what was going on - our service haven't been down - I guess it was something from Twitter.

RE: Silvester - A Silverlight Twitter Widget

vasudev — Tue, 06 Jan 2009 00:50:49 GMT

Hi emil, Again today at present the tweets are not showing. Just displays the black background with 'Refresh' , 'Follow Me' links.

Justin Angel — Fri, 26 Dec 2008 01:06:04 GMT

Thanks, I'm now using this on my official blog at Silverlight.Net: http://silverlight.net/blogs/justinangel.

I've chosen to use this because it's the BEST twitter widget, not just because it's silverlight. Way to go folks!

hm... I've try it on my blog: http://weblogs.asp.net/emilstoichev/archive/2008/06/26/silvester-silverlight-twitter-widget.aspx

works perfect... Please let me know if you find something. Thank you.

RE: Silvester - A Silverlight Twitter Widget

vasudevg — Fri, 28 Nov 2008 05:09:56 GMT

Again its not showing tweet contents, Just showing the empty box. Have to check if its tweeter problem or Silvester's.

RE: Silvester - A Silverlight Twitter Widget

vasudev — Fri, 28 Nov 2008 04:52:16 GMT

Thanks emil, I have put it back now on my blog.

RE: Silvester - A Silverlight Twitter Widget

emil — Tue, 18 Nov 2008 02:40:33 GMT

The widget can be used again! Since we moved to a new hosting environment there should be no problem to put the widget on your blog/site/etc. Enjoy!

Too bad none of the silverlight examples here work. I have the addon yet the examples just ask to download silverlight. MS needs to fix this to be serious abotu promoting this tool.

RE: Silvester - A Silverlight Twitter Widget

emil — Tue, 21 Oct 2008 06:28:26 GMT

Yes, I know about that. There is a breaking change in Silverlight 2 RTW that validates the MIME type returned on the HTTP response is application/x-silverlight-app. Currently our hosting provider hasn't configured the IIS correctly and returns application/octet-stream. That's why the XAP file is only downloaded but the Silverlight doesn't run. I've already send a support ticket and I hope they fix behavior.

RE: Silvester - A Silverlight Twitter Widget

vasudev — Tue, 21 Oct 2008 06:13:44 GMT

Its still not working, If I open this page I can see the Widget, but when code put in the blog, it just displays white patch. While I can right click on that white patch and get SL Configuration window.

Any help on that, emil?

RE: Silvester - A Silverlight Twitter Widget

emil — Wed, 15 Oct 2008 07:04:47 GMT

Sure, I'll update Silvester within the end of the week. Sorry, busy week :(

RE: Silvester - A Silverlight Twitter Widget

Enrai — Wed, 15 Oct 2008 04:29:31 GMT

Yes, Silvester will be converted as soon as possible to the Silverlight 2 Final version. :)

RE: Silvester - A Silverlight Twitter Widget

vasudev — Wed, 15 Oct 2008 04:20:36 GMT

Yes its broken with SL2 RTW, please update Silvester.

RE: Silvester - A Silverlight Twitter Widget

Offbeatmammal — Fri, 10 Oct 2008 13:36:06 GMT

Any plans to update/re-release as a SL2 RTW version? I was using the RC0 bits and realised it's broken :(

You can get them from http://silverlight.net to check

RE: Silvester - A Silverlight Twitter Widget

emil — Mon, 29 Sep 2008 05:57:41 GMT

Thank you for the idea Offbeatmammal. I'm planning some new features for the next week so may be then I can submit it.

RE: Silvester - A Silverlight Twitter Widget

Offbeatmammal — Fri, 26 Sep 2008 14:07:38 GMT

Have you thought about submitting this to http://apiwiki.twitter.com/Open+source ... would be awesome if the Twitter folks saw it and made it a standard offering alongside the Flash badge :)

RE: Silvester - A Silverlight Twitter Widget

vasudev — Thu, 14 Aug 2008 01:13:25 GMT

It opens the twitter page based on 'Name' in the Twitter settings and not on 'Username' when clicked on displayed name in Tweet. This has to be corrected or am I missing something?

Funny Silvester. haha. Made a geek's day a little lighter. haha

RE: Silvester - A Silverlight Twitter Widget

emil — Thu, 26 Jun 2008 14:21:19 GMT

Tim, not exactly... they've added our domain in the crossdomain.xml file - the Flash format. Unfortunately, to enable Silverlight applications to access services hosted on domains containing only crossdomain.xml, the policy file should be configured to allow access from any domain as described in MSDN. For now we should stick to the proxy service.

RE: Silvester - A Silverlight Twitter Widget

timheuer — Thu, 26 Jun 2008 12:57:07 GMT

i see that Twitter added you to their cross domain list...so you should be able to eliminate the proxy service now right?

This is a great resource for the Silverlight community. Thanks for sharing this! I've been looking for a great example of Silverlight and Twitter working together.
