Out-of-Process COM Components
OutProc Presentation OutProc Class Diagram, OutProc Sequence Diagram
OutProc ST Structure Chart, OutProc MT Structure Chart IDL Demo - Interfac
We looked at this before. It's here as a reminder that all the interface method parameters were being marshalled between the client and component processes. Raw C++ Out-of-Process Single-Threaded Apartment Component
We will go through this code carefully so you see the structure of an out-of-proc COM component. Raw C++ Out-of-Process Multi-Threaded Apartment Component
We will make a quick comparison of this with the previous code so you see the differences between ST and MT code. ATL Out-of-Process Single-Threaded Apartment Component
This is the ATL-based version of the OutProcST project. OutProc with console
Out-of-Process components have no visible interface unless you add one. This demonstrates how to add a console. OutProc with dialog
Out-of-Process components have no visible interface unless you add one. This demonstrates how to add a dialog. -
COM Apartments
COM Apartments Presentation Thread Rules Understanding COM Apartments, Part I - Jeff Prosise, Understanding COM Apartments, Part II - Jeff Prosise Eight Lessons from the COM school of Hard Knocks Marshaling Interface Pointers between Client Threads
You can't pass interface pointers between apartments witout marshaling. To do so breaks the COM threading model. This project shows you how to do that marshaling. Component calls component
This project demonstrates how to marshal an interface pointer through a COM interface. Look at the IDL for the OutterComp. You will see it pass an interface pointer to the InnerComp back to the client. The inner component is created by the outter component, but at the end the client needs to access the inner component to get its state information, so the client just uses the returned (marshaled) interface pointer for that. -
