• Visual C# Creating a Generic class with constraints and also Inherits from a base

  Is it it possible to have a generic class inherit from a base I can't find an example of the syntax, so I don't know if it's possible or not.

• .NET Development Interop layer throws System Exception (cast) when accessing unmanaged COM code

  I would appreciate help/comments on the following... I am trying to access a COM component written in Fujitsu NetCOBOL from C#. I have spent many hours (days...) reading the docs, trying various combinations, and looking at the samples but my attempts are failing miserably. The COM .dll is called "AVSCOMSVR" and the embedded TypeLib has been picked up and converted to an Interop Assembly by VS 2005. Here's a picture of the generated interfaces and Classes: http://homepages.ihug.co.nz/~dashwood/dashwood/AVSProject2.jpg I find this a little puzzling... VS2005 seems to have duplicated the interfaces, some above the Class entry and some subordinate to it, but that may be OK and just reflect my limited understandin ...Show All

• Windows Forms Adding a control to another application

  I am trying to integrate a custom control that I created into another application. The application that I am trying to integrate into has 3 frames in the main wondow.

Is it possible to add a custom control to the frame of the external application I checked with the spy++ utility and the handle is made properly to the correct frame in the window.

• Visual Studio Bug? Assigning shortcut key fails

  When navigating code by words (Ctrl+Right or Ctrl+Left) I much prefer the Emacs version of word boundaries, which skips over punctuation. Using Tools > Options > Environment > Keyboard I can apply the entire Emacs keyboard mapping scheme and get this style of word navigation along with everything else. But I want to use the default Visual Studio keyboard mapping scheme and just change the binding of the Ctrl+Right key (in Text Editor scope) to be Edit.EmacsWordNext. When I do this however and hit Ctrl+Right, the cursor doesn't move at all. Same behavior in Visual Studio 2005 with or without SP1.
