This isn’t really a bug in the .NET compilers, but it sure is an interesting namespace scoping issue that could easily be encountered. If this teaches you anything, be it that you should never name a nested namespace level the same name as one of its parents in the hierarchy. In C# First here’s the Compile Time Exception that I was getting: The type or namespace name ‘Data’ does not exist in namespace ‘MyApp.Data.MyApp’ (are you missing an assembly reference?) At first I was like “What do yo... [More]
I was looking over some of the old prototypes I've written in the past, and I can across a Simple Port Scanner that I originally wrote in VB.NET 2003. I originally wrote this back in 2004 (I think), and even posted a compiled version on my website that I have since removed/deleted. So, since it's just sitting on my hard drive collecting virtual dust, I thought I'd post it here in case anyone else can find it usefull.
This Port Scanner implements Multi-T... [More]
Originally, I started out as a Visual Basic developer, and have since moved mostly to C#. However, when doing consulting work, I do need to cross back and forth quite often. Here are a couple VB.NET tips that you probably aren't aware of if you're mostly a C# developer. Some VB.NET developers may not even know about then either.
Null Coalescing is really simple in C#:
// If "someValue" is Null then set "i" to 0 (zero) // otherwise set it to the value of "someValue" in... [More]
When I was creating my new blog site (this site your looking at), I chose to write it in C#. I had a problem with the App_Code folder because I had some code in VB.NET code and some C# code I needed to put in there. I didn't want to rewrite my VB.NET code in the App_Code folder just so I could write the rest of the code for the site in C#.
Luckily, the ASP.NET Team had already thought about just this kind of circumstance. They implemented a way to partition the App_Code folder into sub-fold... [More]
This last weekend I expirimented a little bit with extending the functionality of the RichTextBox control. Below you'll find an example of a small class that enherits from the RichTextBox control and allows you to implement syntax highlighting (with the use of a couple Win32 API call to smooth over the process of course.) The code pretty much speaks for itself.
