project?

Hello Michael,
I am supposed to provide an OCX for a platform that accept only embedding OCX.
And I am supoosed to provide an image viewer that is build in .Net DLL.
I want to develop an wrapper interface of this DLL as an OCX.
I thought two different ways might be a solution.

1) Creating a .Net that outputs OCX.
2) Creating an OCX project that references .Net DLL.

The former one would be the prettiest if possible while I found no way for
the latter option to import managed .Net DLL into MFC ActiveX C++ project.

That's exactly the problem I need to find a solution for.

Thanks in advance for your support

Your only option is to build the OCX (ActiveX control) in an unmanaged
language (like Delphi, VB6 or C++ using MFC or ATL). There is no way to
build ActiveX controls in managed code.
What scares me a bit is this: "... for a platform that accept only
embedding OCX" - Are you aware that wrapping a managed code assembly in a
native code AX control implies COM interop, this requires .NET to be
installed at runtime, don't expect this to run on a system that doesn't have
the Framework installed.

Hello Willy,
Thanks for your suggestion. I mean by the platform is the development
environment. The final runtime is Windows XP Pro and there is no problem
with running .Net Framework.
