Fingerprint ActiveX

[=?iso-8859-1?Q?Mario_Cer=F3n_Charry?=]

i'm building a web app for capture fingerprints with a suprema SFR300
sensor. The sdk is not an activex, is a dll and wrappers in .NET for access
dll. I need to build an activex that enable the capture in an aspx page.
Where can i find information about it or how can i do this?

Thanks a lot!!!

Re: Fingerprint ActiveX

You'll want to read about exposing C# objects to COM. Unfortunately, while
..NET has pretty good support for wrapping an ActiveX control in C#, it
doesn't go the other way very easily. Unless you can find a library out
there that does this already, you'll have to implement all the ActiveX
interfaces by hand, I believe. There are something like 20 interfaces
(IOleObject, IOleInPlaceObje ct, IOleControl, IDataObject, IViewObject2,
IConnectionPoin tContainer, etc...) for an ActiveX control.

I also believe I read something somewhere about .NET not being able to host
controls in ActiveX containers. I don't know what the specific problems are,
so it may not even be possible. At the very least, it is certainly a
non-trivial task.

Re: Fingerprint ActiveX

Thanks Fredo, but i really need do that. Where can i find information about
it, MSDN is not a very explicit about it and i don't see any example.

Thanks

Re: Fingerprint ActiveX

Well, then for information about how to implement an ActiveX control, you
can start here:

http://msdn2.microsoft.com/en-us/library/aa751971(VS.85).aspx

This will get you started on implementing COM servers in C#:
