Problems with IFont and IPicture using ActiveX control

I am having problems setting some properties of elements in an ActiveX
control (AddFlow from Lassalle Technologies). Specifically, I am having
difficulties setting fonts and pictures as the control will not accept
TFont or TPicture objects for these properties. How can I convert TFont
to IFontDisp? How can I convert TPicture to IPictureDisp.

I am using Delhi 4 Pro.
