I suggest you take a look at the [SHChangeNotify][1] API call, which can notify you of all kinds of shell events. To monitor file creation and deletion activity, you may want to pay special attention to the SHCNE_CREATE and SHCNE_DELETE arguments.

[Google first hit](http://www.prescod.net/rest/rest_vs_soap_overview/) seems pretty comprehensive.

Assuming finalizers are similar to their .NET namesake then you only really need to call these when you have resources such as file handles that can leak. Most of the time your objects don't have these references so they don't need to be called.

The GC does a lot of optimization on when to properly finalize things.

Yes you can. I suggest using a tool like robocopy. |
you could use the 'net' commands to authenticate and then copy the files.

Maybe there is a design problem in your tests.
Usually each test must not depend on any other tests, so they can run in any order.
Each test needs to instantiate and destroy everything it needs to run, that would be the perfect approach, you should never share objects and states between tests.

Yeah, my question was not very well put. Here's a solution but rather than a single pass with a regex, I use a split and perform iteration. It works as well but isn't as elegant:

string[] nodetests = xpath.Split( new char[] { '/' } );

The Decimal data type although precise might not be the optimum choice depending on what you want to do. Generally Direct3D and GPUs use 32-bit floats, and vectors of 3 (total 96 bits) to represent a position in x,y,z.
