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...

This is about the simplest way I've found. See [this](http://stackoverflow.com/questions/1092463/getting-the-mac-address-of-the-remote-host) and [this](http://stackoverflow.com/questions/1092379/want-to-get-mac-address-of-remote-pc/1092392#1092392) a...

For both gmail and gApps, use smtp.gmail.com on port 25 with SSL and NetworkCredentials. Neither can send email to their own address, but they can send to other addresses. [NLog](http://nlog-project.org/) has [an example](http://nlog-project.or...

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...

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);...

This snippet builds on my last snippet regarding [User input validation in Visual Studio .NET using MaskedTextBoxes and an ErrorProvider](http://snipplr.com/view/22419/user-input-validation-in-visual-studio-net-using-maskedtextboxes-and-an-errorprovi...

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...

Since an asynchronous method is usually one you call and then it invokes a callback when it is finished, it is not obvious how to test such a method in a definite manner. In the method described at the above URL, the author uses .NET's System.Threadi...

When I'm running unit tests, I find it very annoying to have to check equality within loops when I've got two collections of data. I know of no built-in way (let me know if there is one) [Edit: [CollectionAssert](http://msdn.microsoft.com/en-us/libra...

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...

Specifically, this code enables you to pass a string from C# into C++ managed code and then get a C++ pointer to the string's chars. [Marshal.StringToHGlobalAnsi Method](http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marsha...

This snippet is actually tested for SQL Server Compact Edition (CE) 3.5, but it will probably work for other SQL Server editions. Once you have an SQL CE db up and running, you can set the connection string to point to any directory and database by s...

See [Raise and Handle Events Generically](http://snipplr.com/view/15033/raise-and-handle-events-generically/) for a better way to use events (generically) and links to best practices in .NET events. This example should be used as a Console program...

If you add a ContextMenuStrip (the menu that shows up when you right-click on something) to your design, you can conveniently have more than one form control use that context menu. The only problem is that you don't know which control the context men...

This routine can be used to copy the byte values of a float or double. The "isBigEndian" variable needs to be determined (most PCs are little-endian, whereas most embedded microprocessors are big-endian). Instead of using unsigned chars, it can be us...
