Some time ago I have started posting about Facebook Application Platform (see my posts about setFBML and Facebook libraries for .NET). Today’s topic is fb:editor. As you may see, Facebook has nice look and feel, and all applications usually adapted in some way to its interface. fb:editor FBML tag allows you to create forms which looks just like native ones, but it has great limitation: it generates it’s own form tag, so can’t be used within ASP.NET server form. In this short post I’ll show HTML generated by fb:editor and a way how to use it in your ASP.NET application.
Last week I faced strange bug in Facebook Developer Toolkit. When I tried to call setFBML method (I mentioned it in my previous post) I’ve got an exception about invalid signature. “Haha” I said and downloaded toolkit sources. After some debugging, I’ve found a few lines which just killed me:
// Compute the MD5 hash of the signature builder
hash = md5.ComputeHash(Encoding.Default.GetBytes(
In my current project we decided to build a Facebook application. This is really great platform with many interesting ideas inside, which usually means that you will spend a much time to make your application working as expected. Today I wanna talk about user profiles. Any Facebook application could add some action links, which will be displayed under the user’s picture, and some content for wide or narrow column. Of course, you can use FBML syntax, especially fb:if-... tags set to choose which content to show on specific profiles to concrete users.
