I have tried this on "Micro$oft-ish so called operating systems"  it worked when
I addionally made the window visible.
    if (!(HTSocketWin = CreateWindow(className, "stop loop with ESC",
WS_POPUP|WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
0, 0, wc.hInstance,0)))

Eventloop:
    while (!HTEndLoop && GetMessage(&msg,0,0,0)) {
  if ((msg.message == WM_CHAR) && (msg.wParam == ESC))  { //linn
   if (MessageBox(HTSocketWin,"Stop the Loop ?","Loop
Control",MB_OKCANCEL|MB_ICONSTOP) == IDOK) {
 //   HTHost_killAll();
    HTEndLoop = -1;
   }
  }
     TranslateMessage(&msg);
     DispatchMessage(&msg);
    }
