HOWTO: Use MFC to Create and Show a PowerPoint PresentationID: Q180616
|
This article shows how to automate Microsoft PowerPoint using the Microsoft Foundation Class (MFC) library version 4.2 (installed with Microsoft Visual C++ versions 5.0 and 6.0). Specifically, this article illustrates how to create and show a PowerPoint presentation with automation.
You can copy the code in this article to the message handler function of an event defined in an MFC .cpp file. However, the purpose of the code is to illustrate the process of using the IDispatch interfaces and member functions defined in the Msppt8.olb type library. For PowerPoint 2000, use the Msppt9.olb type library. The primary benefit comes from reading and understanding the code in the example so that you can modify the example or write your own code to automate Microsoft PowerPoint 97 using MFC.
