• Accidentally created VB.NET project instead of C#

  - by Bryan M.

  This should seem simple enough, but can't figure it out. I was porting a project out of MonoDevelop and into VS2008, but I accidently created the project as VB.NET instead of C#. Now ReSharper and any syntax highlighting is throwing a fit because it's trying to validate it as VB. How do I tell it to treat it as a C# project without creating a whole new one?

• Way to partialy match a Ruby string using Regexp

  - by Fabiano PS

  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

• Java: JButton actionListener explantation

  - by MrDoctorProfessorTyler

  I am extremely confused as to how a JButton works. I have read over the oracle documents of the JButton, but I have failed to see how a JButton can have an actionlistener added to it. I have really always wondered how things like JFrames and all that can have things like .addMouseListener and all that. Can anyone explain how a JButton can have an actionListener added to it like the .addActionListener(...) syntax?

• C++: Pass array created in the function call line

  - by Jarx

  How can I achieve a result like somebody would expect it according to the following code example: // assuming: void myFunction( int* arr ); myFunction( [ 123, 456, 789 ] ); // as syntactical sugar for... int values[] = { 123, 456, 789 }; myFunction( values ); The syntax I thought would work spit out a compile error. How can I define an argument array directly in the line where the function is called?

• Why doesn't web browsers have built in validators?

  - by August Karlstrom

  As far as I know there is no web browser with built in validators for HTML, CSS and Javascript. Developing web pages without validation is like using a compiler that doesn't do syntax analysis. Even Firefox with its excellent plugins aimed at developers like Firebug lacks plugins for CSS and Javascript validation. Wouldn't it be useful to have these plugins? Am I missing something?

• Passing direct parameters to a Controller#method when testing via RSpec

  Normally to pass parameters via in RSpec we do: params[:my_key] = my_value get :my_method Where my_method deals with what it received from params.

I've tried get :my_method(args) but Ruby interpreter complains about syntax error.
