All,

We have a COM object wrapping a single-threaded dll. This worked fine for
individual clients; in the web world, it locks when more than one user tries
to hit it at the same time. For various reasons we cannot modify the dll.

We are thinking about rewriting the COM wrapper as an out-of-proc .exe
instead. I realize this breaks the ability to run tlbimp against it to
create a .NET assembly/dll. My question is, how can one go about
instantiating an instance of an out-of-proc .exe from within a web form?

Thanks,
// Chris

Tlbimp runs against any file containing a COM type library. This file can be
a .tlb, .dll, .odl, .ocx, .exe

per chance, are you using the same instance of objects from that
single-threaded dll for all clients? i.e. storing them in the IIS
Application space?

I create unique instances of the multithreaded COM wrapper for each, but
they are all running within the IIS process. So the thread locks because of
the .dll (cvs2ntlib.dll), which is why we are looking into running it
out-of-proc. Since tlbimp works with COM .exe's it looks like it's ok.

The cvs2ntlib library allows Win32 machines to interface to CVS running on
Linux or Unix boxes. Interestingly enough, over concern about the
security/performance issues with running out-of-proc in a web environment, I
dug around the 'net last night and found there is a CVS server application
written for WinNT - called CVSNT, no less. I don't suppose anyone has heard
about this product? This would be an optimal solution as it eliminates the
need for two whole layers - the COM wrapper and cvs2ntlib.

Regards,
// Chris

Fantastic. For some reason I thought it was limited to .dll's and .ocx's.

Thanks,
