Creating a wxActiveXContainer

My objective is to display an active x object in wxwidgets.

I have declared two member pointers:

TeeChart::ITChartPtr mpChart;
wxActiveXContainer* mpAx;

I then create an instance of the teechart control:

mpChart.CreateInstance("TeeChart.TChart");

I then wish to create an instance of the wxActiveXContainer defined as:

wxActiveXContainer (wxWindow *parent, REFIID iid, IUnknown *pUnk);

However, I am not sure what to pass in for the IUnknown parameter?

Currently, I have:

mpAx = new wxActiveXContainer(this, __uuidof(TChart), NULL );
Solution

  • mpAx = new wxActiveXContainer(this, __uuidof(ITChart), mpChart.GetInterfacePtr());
