Smart Device ActiveX Controls

I have VC++ 2005 .NET Pro version. I know how to create ActiveX controls,
but how do I use them. When I create a new dialog application, right click
the dialog box and select Insert ActiveX Control, a list pops up that shows
the ActiveX controls I can select. The control I just created does not
appear in that list.

When doing the same thing with eVC++ 3.0 compiler I had to also make a
desktop control using VC++ 6.0 compiler, then modify the project file so that
it would use the same source code. That worked well. Do I have to do
something similar with 2005 compiler ? If yes, can somone please tell me how or post a link to relevant article.

Thanks

VS2005 has a wizard for Smart Device ActiveX MFC controls
one of the options is "Available in Insert Object dialog", but it seems not usable for WinCE, so you still need to create desktop sibling
