About Messages and Message Queues

https://msdn.microsoft.com/en-us/library/windows/desktop/ms644927(v=vs.85).aspx#

Here are some information for dotnet developers:

• Application.Run internally maintains the message/event loop

• Control.BeginInvoke is similar to PostMessage

• Control.Invoke , though internally implemented using PostMessage, will wait for the execution to complete like SendMessage

• WinFormSynchronizationContext or WPF Dispatcher should be used instead of Control.BeginInvoke/Invoke, because the Control might be already disposed when you call its BeginInvoke in another thread, whereas the SynchronizationContext maintains its own control that has a longer life time scope.

• Application.DoEvents: https://msdn.microsoft.com/en-us/library/system.windows.forms.application.doevents.aspx the example in this document explains quite well the scenario it can, but not necessary, be used.

All the above (except the Application.Run) are signs of bad design, I post them here just to help you understand the existing code.
