• JesperChristensen Where's my Immediate window???

  I load up a web project or a win forms project, run it and get the debugger and the project loads. I put in a break point, it stops on the break point.

• GaryMcCan Switching off computer using C#

  Is it possible to switch off computer using c# I know that it is possible when using c/c++. There is a method called exitWindows or exitWindowsEx, but I can't find it in Visual C# Express Edition 2005 The .NET framework must by definition call Win32 functions, but it does not expose all the functions that exist. pInvoke fills this gap. The following is a C# class that deals with all the traps involved in s ...Show All

It is not really for performance but to catch bugs like ...Show All

• rp666 RTM Web refactoring... Serious problems!!

  I am amazed that the refactoring support in VS2005 is in this state. It is utterly useless. How can they claim to have Refactoring support for web projects I have a Solution that contains one web project and two library projects. It is NOT a complicated solution (~150 .cs files and maybe 100 .aspx and .ascx skin files). And when I try to use ANY of the refactoring tools that have been provided in Visual Studio 2005, it takes an eternity (over ...Show All

• Jemue using keywords

  Hi everyone, I have some doubts about the usage necessity of using keywords. Instead of using this keyword, it is enough to only add the packages into our Assembly(DLL files), so inspite of this, why do some programmer do both of them(add the packages into Assembly and also use using keywords for these packages).

I also know that if you write a class and then make its constructor private it will not be accessible to calling classes, therefore making it impossible to instantiate the class. The problem I am having is that certain classes in the C# language give an error of "no constru ...Show All
