MFC: PostMessage and Handling it without the hassle (and a question).

Well, you would really want to NOT put the invoke of the lamba inside the CS lock.
For one it might cause a deadlock (and it certainly will if the lambda again posts more lambdas) [...]

A programmer must never say "certainly" before testing.
Try this...

    theApp.PostLambda([=]()
    {
       AfxMessageBox(_T("There was an old man of Five Rocks"));
       theApp.PostLambda([=]()
       {
          AfxMessageBox(_T("Who shut his wife up in a box."));
          theApp.PostLambda([=]()
          {
             AfxMessageBox(_T("When she said \"Let me out!\""));
             theApp.PostLambda([=]()
             {
                AfxMessageBox(_T("He replied \"With no doubt"));
                theApp.PostLambda([=]()
                {
                   AfxMessageBox(_T("You will spend all your life in that box.\""));
                });
             });
          });
       });
    });

...and see that no deadlock occurs.
But of course, me either don't say "certainly" in a gazillion of other possible cases.
