I ain't a windows guy so take this with a grain of salt.

1) Yes, I believe they have. Brent Fraser did something years ago as
did a
couple of other users. You might post a note to the main list.

2) No idea, never written a COM object in my life... ;-)

3) I'd go COM over ISAPI simply because you get more bang for your
buck. I
tend to use MapScript outside of a web environment than in one. Forgive
if this is a stupid question, but with .NET is COM dead or is there
something set
to replace it?

Dear Steve,
	Thank you for your offer to help me out, After looking at
MapScript and the
documentation of SWIG generated interfaces, I believe MapServer-COM
be wrapped the same way, Actually the Idea behind the COM wrapping of
MapServer is to interface it to IIS/MTS and thus reap the benefits of

You map please help me in these areas:

1.Has any one tried a similar thing on MapServer before, If yes, Can I
from you any additional Info abt COM-Mapserver, issues with it...and
on,Steve any additional Info stops me from re-inventing the wheel.

2.The Design Issues with COM??? any guidance from you.

3.Do you suggest any alternatives as such for what I plan to implement
COM, the COM idea came after in-depth analysis for creating an ISAPI
dll of
MapServer, and shelving the idea in the conceptual stage in favor of
advantages of COM over ISAPI, Steve What do you comment on this? do
agree? what does your experience say?

I will be in constant touch for the rest of this endaevor,Looking
for a nice time with you and MapServer
Thank you and all my regards

I think it would make the most sense for a COM module to follow
MapScript. Assuming your dll is destined for public consumption that
would make it much easier to use. The file mapscript.i in the
directory documents much of the SWIG generated interface. I can help
further if this is of interest to you.
