Yes, there is no standard but libraries like **Qt** and **boost** can make your life much easier when you do cross-platform development. |

I actually develop in .NET, run all my tests first on Mono, and then on Windows. That way I know my applications are cross platform. I have done this very successfully on both ASP.NET and Winforms applications.

Actually, you're not quite right about that you cannot specify what types a method expects, it does work as you'd expect.

And so on, and you can even pass in your own classes as expected parameters. Calling the methods/functions with something else will result i... |

I actually don't think the compiler is wrong, although this is an odd case.
From a code analysis point-of-view, it sees you storing the address of a variable, but that address is never dereferenced and you don't jump outside of the function to external code that could use that address you stored. When you exit the ... |
You'll have to add a reference to Microsoft Visual Basic for Applications Extensibility 5.3 (or whatever version you have). I have the VBA SDK and such on my box - so this may not be exactly what office ships with.

You don't use an img tag, but an element with a background-image css attribute and set the background-position on hover. IE requires an 'a' tag as a parent element for the :hover selector. They are called css sprites.

Yeah, make sure you have a sensible editor set. Not sure what you're default editor will be but if, like me, it is nano (will say somewhere near the top after you type commit) you just need to type in a comment and then hit Ctrl-x to finish. Then hit y, followed by enter to affirm the commit.

SVN only controls what you put into it when creating your repository. Don't just import your entire project folder but import a "clean" folder BEFORE doing a build. After the build you get all the object files or your _Resharper folder etc. but they are not version controlled.

I don't agree. Object Oriented Programming is not inherently better than procedural programming.
