I believe that HDirect allows you to do this. Unfortunately, I don't know of a binary build of a recent version, and I have yet to manage to build it myself :-(

Latest version is from January 2004, hierarchical library layout has changed a bit since then :( It doesn't compile for me, either. Anyway it seems to be a bit of overkill for what I want to do. I'm not aware of any other libraries to do this. Thanks for the pointer! Paul.

A bit of searching turns up very little, but rolling your own for simple support is not difficult. OleInitialize, CoCreateInstance, class IUnknown, class IDispatch, class Variant...

Yes, I know. But I did not want to reinvent the wheel :) Besides, HDirect is large pile of outstanding work. Probably very much worth resurrecting. I'll think about this. Anyway automation bindings could be a bit of boost for Haskell popularity on Windows. -- Gracjan

Hi. I spent much time trying to get it to work.. you have to download the whole fptools directory (from cvs!).. and I think i did some little patches but I can check out again and compare.. It did compile and I think it's working well but I'm still struggling getting to use it.. At least the examples do compile!

If you are really interested I would appreciate getting in contact with you (my private email: marco-oweber a t gmx.de) .. Perhaps we can help each other. (Becaue I'm not an experienced haskell programmer, yet ;-) I've been trying to get hdirect to build and would also appreciate any hints. Sounds like I should try the version from CVS?
