• why can't a static member be reached through an instance name?

  - by reinier

  say I have: class Test { public static int Hello = 5; } This obviously works: int j = Test.Hello; But why should this not work? Test test = new Test(); int j = test.Hello; The instance could not have a member equally named, so I don't see how this could be ambiguous or unresolvable for a compiler. Anyone any idea why this is?

• What can we do to make Microsoft add IntelliTrace to VS 2010 Professional Edition?

  - by Ikaso

  Now that Microsoft has released VS 2010 I went to the product page here. To my amazement I found out that IntelliTrace(Historical Debugger) is supported only on the Ultimate Edition of VS 2010. This mean that you have to spend almost $4000 for renewal and almost $12000 for a new license. Does someone have any idea how can we change this decision? Especially make them add this feature to VS 2010 Professional Edition.

• chrome-like status bar in qt

  - by hasen j

  I'm not big on creating GUI's, and generally my philosophy is: I don't create them, or I make them as simple as possible (and convince myself that it's better for usability :) For my current project, I'm using Qt from Python (PyQt), and I want to start adding some GUI elements without cluttering the interface. My idea is to create these elements as sort of floating-shaped-widgets that only appear when necessary; pretty much like the status bar (and find bar) in chrome. Is there any standard api that enables creating this kind of interface?

• How to display data uri scheme into a C# WebBrowser Controler

  - by Emanuel

  How can I show an image base64 encoded using WebBrowser control in C#? I used the following code: <img src="data:image/gif;base64,/9j/4AAQSkZJRgABAgAAZABkAA7AAR R894ADkFkb2JlAGTAAAAAAfbAIQABAMDAwMDBAMDBAYEAwQGBwUEBAUHCAYGBw ... uhWkvoJfQO2z/rf4VpL6CX0Dts/63+FaS+gl9A7bP+tthWkvoJfQODCde4qfcg RiNWK3UyUeX9CXpHU43diOK915X5fG/reux5hUAUBftZ" /> but no image is displayed.

• How to 'do' ByVal in C#

  - by Jouke van der Maas

  As I understand it, C# passes parameters into methods by reference. In vb.net, you can specify this with ByVal and ByRef. The default is ByVal. Is this for compatibility with vb6, or is it just random? Also, how can I specify what to use in C#? I kind of like the idea of passing parameters by value.

• Implementing dynamic scope when using CPS as intermediate language

  - by asandroq

  I am currently studying the implementation of programming languages and became interested in using Continuation-Passing Style as the intermediate language of the compiler. I also want to implement limited dynamic scope (for exception-handling or Scheme parameter objects) but I cannot find the relevant literature. I think it can be done with a separate environment passed as a variable to every closure, but this solution seems ugly to me. Could anyone point me to the relevant literature, or give me an idea of how this can be done?

• cmake source and out-of-source navigation

  - by idimba

  Hi, cmake advises to use out-of-source builds. While in general I like the idea I find it not comfortable to navigate from out-of-source sub directory to the corresponding source directory. I frequently need the code to perform some actions with code (e.g. grep, svn command etc.). Is there an easy way in shell to navigate from out-of-source sub directory to the corresponding source directory? Thanks Dima
