Using background threads for long processes in MFC: Background Thread 2

We can solve the problem of the memory leak, and of the premature destructor call, by simply blocking until the thread is finished:

void CBgthreadDlg::OnBackgroundJoin()
{
    CWaitCursor wait;

    TaskThread *t = new TaskThread;
    t->Start();

    // Wait for it to finish
    t->Join();
    delete t;
}

This is, in effect, no better than any of our foreground thread examples, but it does get us a step closer to the ideal solution.
