Microsoft’s just released Powershell. (about 2 years ago) I’ve already downloaded it; didn’t try it much, but seems a nice tool.
Using pySerial with Python: import serial.tools.list_ports ports = list(serial.tools.list_ports.comports()) for p in ports: print p
There’s no single answer to that. In fact, that’s precisely why these “SpecialFolder”s are defined. You use those instead of a hardcoded path.

A common example would be a settings or configuration file. Environment.SpecialFolder.CommonApplicationData is similar, but shared … Read more

The best bet if you must use raw pointers is to make sure that it is either a valid pointer or NULL. Then you can check if it is valid by checking if it is equal to NULL. But to answer your question, you can catch these kinds of things with structured exception handling (SEH). … Read more
A GUID would be extremely fast, since it’s implementation guarantees Windows can generate at least 16,384 GUIDS in a 100-nanosecond timespan. (As others pointed out, the spec doesn’t guarantee, only allows for. However, GUID generation is really, really fast. Really.) The likelihood of collision on any filesystem anywhere on any network is very low. It’s … Read more

To track a user’s idle time you could hook keyboard and mouse activity. Note, however, that installing a system-wide message hook is a very invasive thing to do and should be avoided if possible, since it will require your hook DLL to be loaded into all processes.
