SUMMARY

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.

MORE INFORMATION

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 PowerPoint 97 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.

Notes for Automating PowerPoint 2000 and 2002

The sample code in this article uses class wrappers generated from the PowerPoint 97 object library (Msppt8.olb). With slight modification, this code can be applied to an Automation client that uses class wrappers for PowerPoint 2000 (Msppt9.olb) or PowerPoint 2002 (Msppt.olb). For additional information about using the sample code described in this article with the PowerPoint 2000 or 2002 type library, please click the article number below to view it in the Microsoft Knowledge Base:

Steps to Create the Project

  1. Follow steps 1 through 12 in the following Microsoft Knowledge Base article to create a sample project that uses the IDispatch interfaces and member functions defined in the Msppt8.olb type library:
    178749 How To Create an Automation Project Using MFC and a Type Library
  2. Press CTRL+W to display the ClassWizard once more and select the Automation tab. Click the Add Class button and select From a Type Library. Locate Graph8.olb and click Open. Select only the "Chart" class and click OK. Click OK to close the ClassWizard.

    NOTE: The presentation that you will create with this example contains an embedded Microsoft Graph chart; this is the reason for adding the Chart class from the Microsoft Graph type library (Graph8.olb).
  3. At the top of the AutoProjectDlg.cpp file, add the following lines:
          #include "msppt8.h"
          #include "graph8.h"
    					
  4. Add the following code to CAutoProjectDlg::OnRun() in the AutoProjectDlg.cpp file:
       // Commonly used OLE-variants.
       COleVariant
                   covTrue((short)TRUE),
                   covFalse((short)FALSE),
                   covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

          ::Sleep(9000);
          presentation.SetSaved((long)-1);
          app.Quit();
    					
  5. If needed, modify the assignments for strPic1 and strTemplate to valid paths for an image file and a PowerPoint presentation template:
    CString strPic1 ="C:\\Program Files\\Microsoft Office\\Clipart\\Popular\\Amhappy.wmf";
    CString strTemplate = 
             "C:\\Program Files\\Microsoft Office\\Templates\\Presentation Designs\\Zesty.pot";
