Hello,

I currently have a huge problem, hope you can help me.
I have a (Single<>)class which includes a Thread.
I need to use the thread from different positions of my main program.
The problem is, that I need to stop the thread before closing a dialog, but how can I do that? I searched on the site, in the forum, on google... But I found nothing usefull.
All I found was "ShutdownThreads", but this only sets a flag and does not stop the thread itself...
I also tried to Close the Handle after GetHandle(), with no success.

If you need some code, look here:

void TCPConnection::startChecking()
{
	// Thread starten
	if(s.IsOpen()) // s is a Socket Connection
	{
		m_terminateThread = false;
		t.Run(THISBACK(cb));
	}
}

void TCPConnection::stopChecking()
{
	// thread beenden
	if(t.IsOpen())
		m_terminateThread = true;
}

void TCPConnection::cb()
{
	while(!m_terminateThread)
	{
		tempBuffer = s.Read(1000);
		
		if(!IsNull(tempBuffer))
		{
			buffer += tempBuffer;
			tempBuffer.Clear();
			WhenDataReceived();
		}
	}
	
	// CloseHandle(t.GetHandle()); // wont work

bool TCPConnection::hasThreadStopped()
{
	return !t.IsOpen();
}

And on the main program I do the following:

void xxxDlg::onCancel()
{
	if(TcpConnection().s.IsOpen()) // TcpConnection() returns ref on Single<TCPConnection>
	{
		TcpConnection().stopChecking();
		
		while(!TcpConnection().hasThreadStopped())
		{
			Sleep(50); // this is where I stuck... The thread is not closed!!!!!
	 	}
		TcpConnection().s.Close();
	}
	 	
	Break(IDCANCEL);
}

Thanks in advance Wink
