HOWTO: Use MFC to Create and Show a PowerPoint Presentation

ID: Q180616


The information in this article applies to:
  • Microsoft Visual C++, 32-bit Editions, versions 5.0, 6.0
  • Microsoft Office 2000 Developer
  • Microsoft PowerPoint 2000
  • The Microsoft Foundation Classes (MFC)


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 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.

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. For PowerPoint 2000, the project uses Msppt9.olb):


  2. Q178749 HOWTO: Create an Automation Project Using MFC and a Type Library
  3. 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. For PowerPoint 2000, locate Graph9.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).


  4. At the top of the AutoProjectDlg.cpp file, add the following lines:


  5. 
          #include "msppt8.h"
          #include "graph8.h" 
  6. For PowerPoint 2000, add the following lines:


  7. 
    #include "msppt9.h"
          #include "graph9.h" 
  8. Add the following code to CAutoProjectDlg::OnRun() in the AutoProjectDlg.cpp file:


  9.

  10. Modify the following line of code in CAutoProjectDlg::OnRun(), if necessary, to specify the correct path for your installation of Microsoft Office:


  11. 
       CString strOfficePath =    
          "C:\\Program Files\\Microsoft Office"; 
  12. For PowerPoint 2000, you might have to use the correct image file path also because Clipart is not installed with Office 2000.
