EDIT: The first link translates only the source code (.vb) and does a good job at it. I also need to convert the project. The second link ... #develop does not handle...

I've recompiled an existing solution of mine and I'm encountering a Cast exception I did not have before. The structure of the code is simple (although the actual implementation somewhat more complicated). Basically I have: ...
I have a WPF Keyboard Application, it is developed in such a way that an application could call it and modify its properties to adapt the Keyboard to do what it needs to.

I'm using .NET 4 and the new RegistryKey.FromHandle call so I can take the hKey I get from opening a software registry file with RegLoadAppKey and operate on it with the existing managed API. I thought at first it was just a matter of a busted DllImport and my call had an invalid type in the params or a missing MarshalAs or whatever, bu...
