• Visual C++ C++/CLI Translator

  In Stanley Lippman's article, "A Baker's Dozen: Thirteen Things You Should Know Before Porting Your Visual C++ .Net Programs to Visual Studio 2005"; in the introduction, there are three points, "To ease the transition...".  I quote point 2: "We're working on an informal translation tool that can get you 80% of the way there. It will likely be made available for test-driving during the time-frame of the second beta." I can not find this translator.  Was it released If so, what is it's name and where can I get it   The tool is not yet released but it is under current consideration. I will keep you updated!

• Windows Forms Manual deployment using Mage.exe and MageUI.exe

  My goal is to create an automated script to build and deploy our application to a publishing URL. The building is already done and is working great.

Using Mage.exe, I have been slightly less successful. I have tried to follow the same steps I believ MageUI is taking, listed below. I keep getting errrors when installing and running from my client pc though. Steps to reproduce: Create new folder for application to deploy ( ie. bin\debug\1.0.1.3) From the debug ...Show All

  The new generics in C# 2.0 are really breath taking, but I've got some problems with sorting a Generic List. I've got a List<KeyValueType<TKey, TValue>>, so this is a list containing another generic type. Now I would like to sort this list by the TKey type of the KeyValueType<TKey, TValue> type.

• Visual Studio Make a tool window always display on startup.

  How do I force a tool window to display even when in the previous session I had closed the ool window. There must be some point in some interface where I can set the tool window to visible and it will display. However, I would like it to stay closed after it's been closed in the session and then not re-appear unless explicity enabled or visual studio 2005 is restarted. Same way the start page works. Thanks, Darren By default, all tool windows will appear on restart if the window was visible when Visual Studio was closed. The Start Page makes its self the topmost window when it is shown, and you ...Show All
