Fix MicroSoft OCX (C++)

MicroSoft has made a control called [login to view URL] available to the public at [login to view URL];en-us;311765 which hosts Office documents on a form. I need this for a VB.Net project since .Net has no OLE container, and the suggested substute WebBrowser control is too limited. However there seems to be a bug in this control: when a PowerPoint document is hosted it returns NIL for the ActiveDocument property instead of a reference to the Presentation object. The property works for Word and Excel. This DLL comes from MicroSoft "as is" and unsupported and I don't have the time or experience to fix it (assuming it is fixable). ## Deliverables Either demonstrate to me how the existing DLL can be made to work with PowerPoint documents, or fix the DLL (source is available from MS at above link). I need working proof that a VB.Net program can open a PPT doc in this control and retrieve the Presentation object reference from it. ## Platform VB.Net; Office 2K or XP
