I recently got an XBox 360; and until I got one I didn't fully realize what all its features are. This is a really sweet system! So, naturally I downloaded the XNA Game Studio Express to check out what's all possible with building homebrew games for the 360. After registering my gamertag with the XNA Creators Club and installing XNA Game Studio Express on my PC, I took the following steps: Go on XBox Live Marketplace and download the Free XNA Game Launcher.

.NET: How to Alias Namespaces and Data Types

One of the little known features of .NET is that you can give complete namespaces and data types alias's that you can reference them with in code. Aliasing Data Types For this example we'll give a different name to the integer data type: In VB.NET: Imports MyInteger = System.Int32; In C#: using MyInteger = System.Int32; Now to use the alias in code: In VB.NET: Public myVariable As MyInteger = 4; In C#: MyInteger myVariable = 4; Aliasing Namespaces For this example, lets assume ...

Not All Software Developers Need To Be Graphic Designers

I do agree that this is a common problem. And, there is no doubt that the one of the next steps in the evolution of the software industry is betting Graphic Design and User Interf... [More]

In college they teach you a lot of mathematics and how to use that same logical thinking with programming. It's true that if you're good at math, you may have the potential to be good at programming. Development = Creativity The development aspect of building a software solution is the creative aspect to programming. When you design or architect a software solution there is a t... [More]
