Open Cascade in Dialog Based Application

I also want to know how to realize, can anyone help me?
Thank you!

In MFC the following works:

In the dialog editor insert a CButton where you want the OCC view to be (CStatic would probably also work). Initializing OCC is the same, just use the CButton's HWND when creating the WNT_Window:

Handle(WNT_Window) aWNTWindow = new WNT_Window(myGraphicDevice, GetDlgItem(IDC_OCC_VIEW)->GetSafeHwnd(),
Quantity_NOC_GRAY);

Hope that helps,
