Hosting .NET control in unmanaged code (designer)

[pNULL]

Hi,

I have to develop a Form Designer, in un-managed code (C++), and I
have some
custom .NET controls of my own. I want the user to be able to drag my
custom
.NET controls from my toolbar on my form, just as one do in VS.NET. I
want my
user to have a design-time facility, where she will be able to see
how the
control look-like, and set different properties, as we do with any
control in
VS.NET.

Prior to this we had ActiveX control, and for Inplace Activation, at
design
time Ax Controls provide a bunch of interfaces to play with. Is there
any such
thing in .NET?? How can I achieve the same ??

I'll be grateful for a reply.

Regards,
Muhammad Shuaib
