You need a member and method(s) that point to the mschrt20.ocx functions within the mschrt20.ocx module within your module's code. Also you will need to include mschrt20.h in your header file for you module. Then in your OnDraw() use the methods and member, that is in your header file of your OCX file.

Alright, Thanks! I've done that, but the problem is i still getting problem in attach the CDC* from the mschrt20.ocx to my OnDraw(), i'm really lost in MFC/ActiveX programming, but maybe i just need a piece of code on that to get the things moving again.

Presuming you have a:

CDC* m_pchrtMyChart;

in your code then all you should have to do is:

m_pchrtMyChart = mschrt20obj.m_pchrtObj
or something to that extent. Often there is a HANDLE involved in order to transfer information about the object. It is a lot like using Bitmaps.

Thank you for your time The_Inventor!

I've got the problem solved by adding the chart in a IDD_DIALOG
and attaching it to the ActiveX. But the ActiveX must be enabled for control container,
and the dialog must have a bunch of flags setted.
