While you wait for an answer clever than mine, what about taking a glance to this thread with the wonderful code by JLBorges?

I'm completely new to C++ so bear with me. I have some code that someone else wrote

I'm a complete newbie to programming.

So... are you new to programming and you decided to begin by C++ with an undocumented multi-threading code written by somebody else? Is that right?
Wow, let me say I admire you. You really a brave guy. My best wishes.
Hope somebody else will come and help you, I'm a very beginner with multi-threading and I won't be of any help.

I could say the same thing. You don't show any efforts to begin with, and we also can't help someone who doesn't understand anything about C++ at all. Solutions will not help you learn and will likely encourage your laziness.

ok, why does sleep hang the thread? It should put the thread to sleep for 30 then wake up right where it left off. You can put a busy-wait in there, but that kills your performance... burns a cpu for nothing.

If I simply do Sleep(30) it will freeze the app for 30 seconds and the window will not respond.

Sleep(30) only freezes the thread for 30 milliseconds.

And how to create a separate thread so that you can freely use Sleep() without affecting your main window :

Edit : You need to keep your thread alive, not delete it.

The SystemBroadcast is what prints the message so I want a way to do this 4 times with a 30 second wait in between. The message will be different each time. I've only been able to do this with Sleep but obviously that's a bad thing as it will hang the thread.

This is the portion shown that I want to modify. If I need to include the whole thing, just let me know. Thanks.

 CPhatServer::~CPhatServer()
{
	if (g_pNetwork)
	{
		SystemBroadcast("2 Minutes");
		g_pNetwork->Think();
		SafeDelete(g_pNetwork);
	}
	SafeDelete(g_pWorld);
	SafeDelete(g_pGameDatabase);
	SafeDelete(g_pDB2);
	SafeDelete(g_pDB);
	SafeDelete(g_pGameRules);
	SafeDelete(g_pCell);
	SafeDelete(g_pPortal);

	for (int i = 0; i < m_socketCount; i++)
	{
		if (m_sockets[i] != INVALID_SOCKET)
		{
			closesocket(m_sockets[i]);
			m_sockets[i] = INVALID_SOCKET;
		}
	}
}

There's nothing useful in this thread and I'm getting nothing but a hard time here so I'll look elsewhere for help.
