I had hear about a method to run a method like an executable, with the arguments being passed in from the commandline. Apparently, Ruby has this with the Rake project. Well, Python has it with [Shovel](http://devblog.seomoz.org/2012/03/shovel-rake-fo...

Obfuscating .NET code so as to hide implementation details from public view (using BabelObfuscator)
If you weren't already aware, you can use a product like [Reflector.NET](http://www.red-gate.com/products/reflector/) to see all of the source code (that's right, the code) of a .NET assembly (DLL, EXE, etc). This is a real problem when your code is...

C#
Get the network interface card (NIC) from a known MAC address (and get the IP addresses on that NIC)
The code shows how to take a known MAC (e.g. "00:00:00:11:22:33") and locate the NIC which has that MAC. Note that the built-in MAC class for .NET is called PhysicalAddress (in System.Net.NetworkInformation). PhysicalAddress.Parse can take a string,...

Great way to show the user that something is happening without too much tedious work. As simple to use as putting the following code in Form_Load:
AutoWaitCursor.Cursor = Cursors.WaitCursor;
AutoWaitCursor.Delay = new TimeSpan(0, 0, 0, 0, 25);...

I just discovered that the MaskedTextBox control allows you to set the type of data which should be entered in the control and helps you do the validation of that data when necessary. The trick is to set the ValidatingType of the MaskedTextBox contro...

Essentially, you need to tell Visual Studio to generate an XML file with documentation, then use a separate tool to create a help file (usually .chm) out of that XML file. The tool to use is MS's Sandcastle. You'll also want a GUI for Sandcastle, whi...

Say you've got data combined in such a way that there is a repeated row header, but all the data is in different rows. If you were to consolidate all the rows down to one, only taking valid values (discarding blanks), you'd have one header row with a...
