• facebook integration for sites

  - by disappearedng

  Hi everyone, AFAIK, the following are not possible for now: (Assuming we have user A which has allowed us all permissions:) Send a message to a A's friend get A's friends email Aside from the obvious "Like" button, what are the ways that an app can leverage facebook's graph API to increase traffic flow? I find the Like button to be more of a broadcasting mechanism. I was wondering what are the ways that I can specifically tell user B, whom is a friend of User A, that he/she should come check out my site. Many thanks

• Where has MS Charting gone in .NET 4.0?

  - by zotty

  Forgive me for being a little naive perhaps, but it seems that System.Windows.Controls.DataVisualization.Charting has vanished from VS2010, and blend 4. I'm trying to make a bar graph with a line overlayed, but can't even get started because I can't find the appropriate controls. I know I could use an external graphing package, but I'd like to try the inbuilt controls first.

  Does anyone know if there is a library that exists to help test if an object graph is fully serializable? It would probably be as simple as writing it out and reading it back in, but I figured someone must have abstracted this already - I just can't find it.

• set highchart margin

  - by user1392330

  I have built a a higcharts charts and I am displaying them one at a time on mouseover.
