Hi, Stoya
I have another problem again, it is as follow:
When I create a FlowChartX object in the OnCreate() function of CMyView, and run the system there will be an error pop out as follow:
"Debug Assertion Failed, File winocc.cpp, line 374"

And whe I go to that line, it is as follow:
ASSERT(m_pCtrlSite != NULL);//Not an OLE control

Why there will be such a problem? And how can I handle with it?
Thank you, hope for your help!

Yes, I create that two FlowChart Object dynamically, and intend to insert them into two tab pages. I use follow code to create the FlowChart Object in the OnCreate() of CMyView as follow:

if(!m_FlowChart.Create(NULL, WS_VISIBLE, CRect(0, 0, 0, 0), this, IDC_FLOWCHART))
return -1;      

And my emial is: jhlong@trane.com
Please send the runtime license key to this mailbox, thank you very much! And by the way, how to use these runtime license?

And what is the stack trace shown in the VS debugger? My program doesn't gave out any error or warning during complie and debug, but when it run, it will give that error: "Debug Assertion Failed, File winocc.cpp, line 374" 

Thank you in advanced!
