I have a MFC ActiveX VC++ project that create a control to use in some VC# .NET projects.Why I didn't use .NET user control to develop this control because GDI is faster than GDI+ in drawing what I want this control shows.The control works well when it connects to database.Now I want it can accept a .NET DataSet as its datasource.For example if I use this ActiveX control in my .NET project,and I put it in a Form in VC# project,for example I want to have something like this in Form constructor:

public MyForm()
{
       InitializeComponent();
       
       //What I want to achieve
       DataSet dsSource=new DataSet();
       //Populate dsSource somehow
       MyActiveX.DataSource=dsSource;
}

or maybe I can't have this type of properties in unmanaged code(I don't know yet) so I have to implement it in a member function in MFC ActiveX Control.

public MyForm()
{
       InitializeComponent();
       
       //What I want to achieve
       DataSet dsSource=new DataSet();
       MyActiveX.SetDataSource(dsSource);
}

Is there anyway to pass a DataSet (or any other .NET class instance) to an ActiveX control and use it inside unmanaged code?how a .NET class can be used in VC++ unmanaged code?

Thanks for any guide line or reference.
