• Howto play video with external audio in Silverlight?

  - by Fury

  Hi all, Is there any proper method to play synchronously video and external audio, other than simply having two MediaElement (one for video source and one for audio) started simultaneously? I need to play video with different soundtracks, but I belive that just two separated MediaElements will be out of sync at some point of time. Maybe there is some way to add audio source to the existing MediaElement with video? Platform: SL3, but SL4 will be good as well. Thanks in advance.

• Scaffolding Extensions: NoMethodError

  - by marienbad

  Not sure if many people are familiar with Scaffolding Extensions for Ruby, but I've looked through their docs, forums, and even the source code of the Heroku test site, and not found an answer. I made a basic Sinatra app and followed right from the RDoc's instructions: require 'scaffolding_extensions' require 'sinatra/base' class Thingy < Sinatra::Base scaffold_all_models end gives undefined method 'scaffold_all_models' for Thingy:Class (NoMethodError) and I know Scaffolding Extensions is loadable because I can successfully set some config variables in its classes.

• Extension Methods - IsNull and IsNotNull, good or bad use?

  - by Jaimal Chohan

  I like readability. So, I came up with an extension mothod a few minutes ago for the (x =! null) type syntax, called IsNotNull. Inversly, I also created a IsNull extension method, thus if(x == null) becomes if(x.IsNull()) and if(x != null) becomes if(x.IsNotNull()) However, I'm worried I might be abusing extension methods. Do you think that this is bad use of Extenion methods?

  Does anyone know of an easy way to work backwards from the VS2010 code coverage in-file highlighting to the test that provides the coverage? I have a file with one method covered and another not but looking through my tests I can't spot the one providing the current coverage. It would be great to be able to navigate back from the code highlighting. Thanks

• How to translate legacy system colors to (A)RGB?

  - by Paul Sasik

  I have a list of color values encoded as signed integers in a legacy INI file that I need to translate into (A)RGB values with .NET. An INI example: [INI_Section] Color=-2147483633 Doing something like: Color.FromArgb(-2147483633) gives an alpha-blended version of a color that is not at all what I expect. Is there a .NET method for translating these legacy colors properly? Note that pInvoke to OlePro32.dll is not an option.

  How can we generate a link that can be clicked on by 5 different people on a Social Network game, so that each of the five people can get a bonus? The link will be published as a "newsfeed" on the Social Network such as Facebook. The link shouldn't be easily "generated" by any people as a cheating method. Also, what database table(s) should be added to handle: 1) the bonus can be claimed up to 5 times 2) must be claimed by different people ?
