how to declare COM class?

[Yong Chi]

Hello!  I am one of those lurkers who finally decide to write code after 
many attempts.

I declared a COM class best I can from looking at other COM class but I 
am getting syntax errors.  I could not find any guide/manual on COM 
development.

Can someone help or point to a guide on COM development?

Thanks in advance...

For Wine's way of declaring COM interfaces, the best is to read the
ocmments in 'include/wine/obj_base.h'.

If you mean general COM manual, the nicest introduction I found about it is
this URL 'http://www.microsoft.com/Com/news/drgui.asp'.

If it's the Wine part of COM, François's answer is to be read :-)

Out of curiosity, on what are you working on ?

A guid might not help much since wine implements com objects with pure C.
If you get stuck you could mail your code to this list for help.

Yeah, a guuid on COM would be better (sorry for the lame joke).

Anyway, in the Dr GUI URL I sent yesterday, there are some examples of C COM
objects (and a link to Inside OLE where there is some actual C code for a
COM object). As for 'Inside OLE' one can find it in .PS form on the web
using Google :-)
