How to generate UUID (GUID) in C++?

Sample Code:

#pragma comment(lib, "Rpcrt4.lib")

UUID uuid;
::ZeroMemory(&uuid, sizeof(UUID));

// Create uuid or load from a string by UuidFromString() function

::UuidCreate(&uuid);

// If you want to convert uuid to string, use UuidToString() function

WCHAR* wszUuid = NULL;
::UuidToStringW(&uuid, &wszUuid);
if(wszUuid != NULL)
{
  ::RpcStringFree(&wszUuid);
  wszUuid = NULL;
}

How to use named system events (global events) in C#?

There are three classes relating to windows events, EventWaitHandle, AutoResetEvent, and ManualResetEvent.

EventWaitHandle
The EventWaitHandle class can represent either automatic or manual reset events and either local events or named system events.

AutoResetEvent
The AutoResetEvent class derives from EventWaitHandle and represents a local event that resets automatically.

ManualResetEvent
