Hi Kristoffer,

I don't know your program, but if you receive a WM_QUIT in your main 
thread, then maybe you have a OnClose handler or something like this. In 
this function get a handle to the terminate event of your thread and set 
it to signaled, for example:

void __fastcall MyForm::OnClose(TObject *Sender)
{
	SetEvent(MyThread->GetTerminateEventHandle());
	MyThread->WaitFor();
	...
}


I wouldn't post a message like WM_QUIT to the thread (if it has it's own 
message queue) because you can't wait with the WaitFor... functions and 
at the same time wait for a windows message.

Bye,
