In this episode of Defrag Tools, Andrew Richards and Chad Beeder walk you through a common issues in Windows Store applications that use Interop. We use a Windows Store 8.1 app sample to show how missing code affects the stability of the process.
[00:34] - Commonly missed CLR Exceptions
[06:50] - What's an Interop application?
[09:10] - What's an HRESULT? (Microsoft; Wikipedia)
[13:23] - Samples - XAML SurfaceImageSource DirectX interop example
[18:15] - Remove the removed/reset handler to cause an HRESULT based exception
[20:21] - Add an exception handler with associated XAML TextBlock
[23:16] - Sometimes you get System.Exception, instead of the exact exception type
[25:10] - Dump of the unhandled exception... No CLR Exception (!pe)
[28:21] - Email us your issues at email@example.com
[29:34] - DirectX apps on old DirectX hardware
If you have a crash you don't understand, email the CAB file to firstname.lastname@example.org and we'll help you.
