  - by HeavyWave

  There is an issue with PostSharp 1.5 and 2.0 that won't let you install it on the Windows 7 machine with the error message ".NET Framework 2.0 is not present on this computer". To work around the issue you have to run the installer while being logged in with Administrator account. Not Admin group and not "run as Administrator", you have to be logged in with the Administrator account. Hope that helps, if someone has the same issue.

  - by alex

  All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?

• My Android game runs out of memory when it is closed and opened and couple times.

  - by sirconnorstack

  I have an Android game that has an activity for the menu, and then another activity for the game that creates a SurfaceView and Thread to deal with canvas drawing and game logic. When you exit the game and start it up again too much or if you open and close the keyboard (thus restarting the activity), the game runs out of memory, usually when loading a bitmap: java.lang.OutOfMemoryError: bitmap size exceeds VM budget How can I keep all my images in memory without loading them again when the game changes state, or how can I release them from memory and let them reload when the game is restarted?

  - by myotherme

  When generating a strongly-typed Index view for my model I always get the following: <%= Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) %> I am using a POCO class for use with our ORM. As I understand it when using LINQ to SQL the view code will know which field is the primary key. Is there a way that I can an attribute to the property (or class) that will let the View Generator know that the ID property if the primary key?
