Automating MS-Office applications

1.Create a dialog based application and in the App-wizard's step 3 of 6, select the automation checkbox.

2.Create buttons for Start , Run, Close, First Slide, Last Slide, Previous Slide and Next Slide functions and use the following functions accordingly.

3.In your application's InitInstance function , add the following lines.

// Initialize OLE libraries
if (!AfxOleInit())
{
    AfxMessageBox("Failed to initialize OLE");
    return FALSE;
}

4.In your dialog's class , open class-wizard , select the automation tab, select "Add Class" ... "From a type library" and select msppt8.olb from "C:\Program Files\Microsoft Office\Office\"
5.In your header file of your dialog, include the following line.

#include "msppt8.h"

6.Add the following variables in your dialog's header file.

_Application app; // app is the PowerPoint _Application object

Presentations Presentations;
_Presentation Presentation;

SlideShowView View;

SlideShowWindow SlideShowWindow;
SlideShowSettings slideshow;
Slides slides;
_Slide slide;

7.To start PowerPoint, you have to write this code in the Start button's function.

void CPowerPntDlg::OnBtnStart()
{
    // Start PowerPoint and get Application object...
    if(!app.CreateDispatch("Powerpoint.Application"))
    {
        AfxMessageBox("Couldn't start PowerPoint.");
    }
    else // Make PowerPoint visible and display a message
    {
        app.SetVisible(TRUE);
        TRACE("PowerPoint is Running!");
    }
}

8.To open a presentation from the hard disk, add this code in the Open button's function call.

void CPowerPntDlg::OnBtnOpen()
{
    static char BASED_CODE szFilter[] = "PowerPoint Files (*.ppt)|*.ppt||";
    CFileDialog FileDlg(TRUE,"PPT",NULL,OFN_FILEMUSTEXIST|OFN_NONETWORKBUTTON
                |OFN_PATHMUSTEXIST,szFilter);
    FileDlg.DoModal();

    // To get the selected file's path and name
    CString strFileName;
    strFileName = FileDlg.GetPathName();

    if(!strFileName.IsEmpty())
    {
        Presentations = app.GetPresentations();
        Presentation = Presentations.Open(strFileName,0,0,1);
    }
}

9.To close PowerPoint add this code in the Close button's function call.

void CPowerPntDlg::OnBtnClose()
{
    if (CanExit())
        app.Quit();
}

10.To run the slideshow use this code in the Run button's function call

void CPowerPntDlg::OnBtnRun()
{
    Presentations = app.GetActivePresentation();
    slides = Presentation.GetSlides();
    // Show the first slide of the presentation
    slide = slides.Item(COleVariant((long)1));

    //Run the show
    slideshow = Presentation.GetSlideShowSettings();
    slideshow.Run();
}

11.Sometimes, you might want to start all over from the first slide. To go to the first slide you can use this code.

void CPowerPntDlg::OnBtnFirst()
{
    Presentation = app.GetActivePresentation();
    SlideShowWindow = Presentation.GetSlideShowWindow();
    View = SlideShowWindow.GetView();
    View.First();
}

12.And similarly, to go to the last slide

void CPowerPntDlg::OnBtnLast()
{
    Presentation = app.GetActivePresentation();
    SlideShowWindow = Presentation.GetSlideShowWindow();
    View = SlideShowWindow.GetView();
    View.Last();
}

13.Now that you have the slideshow running, you would obviously want to go to the previous slide at some point of time. To do just that, you can use this code.

void CPowerPntDlg::OnBtnPrevious()
{
    Presentation = app.GetActivePresentation();
    SlideShowWindow = Presentation.GetSlideShowWindow();
    View = SlideShowWindow.GetView();
    View.Previous();
}

14.Interested to go to the next slide now ? In that case, this function will help you.

void CPowerPntDlg::OnBtnNext()
{
    Presentation = app.GetActivePresentation();
    SlideShowWindow = Presentation.GetSlideShowWindow();
    View = SlideShowWindow.GetView();
    View.Next();
}
