Whoops. Apparently the OS selects all the text in an edit control 
whenever it gives it focus, so your efforts in WM_INITDIALOG are futile. 
The trick seems to be to clear the selection *after* the OS has set it, 
which you may do in an EN_SETFOCUS notification handler.

   case WM_COMMAND:
     if (LOWORD(wparam) == 199)
     {
       if (HIWORD(wparam) == EN_SETFOCUS)
       {
         SendMessage(reinterpret_cast<HWND>(lparam), EM_SETSEL, -1, 0);
       }
     }
