Is there a better way to marshal an interface across streams that is STA?

[WTH]

I set my Main() to use MTA which works for me, but I wanted to know if
there's a C# class/namespace somewhere that supports/offers the ability to
reproduce what the 'marshal interface into stream' and 'un-marshal interface
from stream' calls in C++?

Thanks,

WTH

WTH,

Is there any particular reason you are using an MTA with your program?
If this is a Windows Forms app, you really need to set it to STA, so that
the controls are guaranteed to work as advertised (some of them will not).

To answer your question, there is nothing in the framework to help with
this kind of marshaling. You will have to call the API's through interop
yourself.

What exactly are you trying to do?

Thanks for the caveat about MTA and controls. This is a very simple form
which shows video, I have a per-form thread that instantiates a copy of my
C++ MPEG4 compression COM object (wraps up DirectShow and some other stuff
for me) but for various reasons I want the compressor initialized prior to
the form's worker thread running so I need to pass the interface to the
worker thread.

I'll reconsider the reasons behind not having the worker thread
create/initialize/hold the COM object entirely, but it kept some things
simpler that way (although quite obviously introducing complexity here,
LOL.)

Thanks for the heads up, as a long-time C++ guy absorbing .NET I certainly
appreciate those types of warnings.

WTH:)
