[Caml-list] accessing COM server, example code ?

[Caml-list] accessing COM server, example code ?

[udo_goebel]

Hi,

I have to access a COM component on win2k. After reading the camlidl doc
this seems to be all right with ocaml. Are there serious restrictions of doing
this within ocaml compared to e.g. C, C++? Is there some example code around
of how to do it in practice in ocaml?

Regards
Udo

Currenly only custom (C++ vtable style) interfaces are supported for COM
clients written using Ocaml/camlidl. Dispatch interfaces are not supported
yet. Among many other things, this means that you will need .idl definition
files for your COM server, type libraries are not enough. You can generate
.idl from type libraries using Microsoft's OleView tool, but for compex
cases that's not an easy task.

Look at examples in camlidl distribution.
