Problem using Mihai's Property List control

I have a problem using the control.

I downloaded the source and made it under VC6.0

To test the control, i inserted it into a sample dialog. But when
I run the application, I get an assertion failure in ctlcore.cpp
(line 662). I think the control was not registered properly (Doesn't
the makefile of your property control register it.)

I even tried with the ActiveX Test Container tool that is shipped with VC6.0

What would've gone wrong?

I tried with the two zips that is available in the net (XPropertiesWndSource.zip and propgrid.zip)


I am new to ActiveX technology.

Thanks for the Help
