Play PowerPoint Slideshow in the Same Window

Posted by James Freeman |
Edraw Office Viewer Component provides a solution for opening then playing the slideshow file in the same window.

Of course you can play it with full screen mode, too. The office viewer component wrapped some common used methods which makes it easy to play and navigate the PowerPoint slide show. It can embed and control multiple instances of PowerPoint on any form or web page programmatically. It can display the PowerPoint slides and play the slides in a window mode.

boolean SlideShowPlay([in] VARIANT_BOOL bLoopUntilStopped)

The following javascript shows how to play the slide show from slide 2.

<script language="javascript" for=" EDOffice1" event="DocumentOpened">

boolean SlideShowExit()

Exits the slide show play window.

boolean SlideGotoFirst()

Goes to the first slide in the opened PowerPoint file.

boolean SlideGotoPrevious()

Goes to the previous slide in the opened PowerPoint file.

boolean SlideGotoNext()

Goes to the next slide in the opened PowerPoint file.

boolean SlideGotoLast()

Goes to the last slide in the opened PowerPoint file.

boolean SlideGotoPage([in] long nPage)

Goes to the specified slide in the opened PowerPoint file based on the index.

long SlideGetCount()

Returns the count of slides.

long SlideGetCurrentShowPosition()

Returns the current show position of slides.

boolean SlideSetStartingSlide([in] long Start)

Sets the starting slide.

boolean SlideSetEndingSlide([in] long End)

Sets the ending slide.

boolean SlideExportSlideToImage([in] long Index, [in] BSTR FilePath, [in] BSTR FilterName, [in, optional] VARIANT Width, [in, optional] VARIANT Height)

Exports the slide to image.

Index: The index of the slide.
FilePath: The name of the file to be exported and saved to disk. You can include a full path; if you don't, Microsoft PowerPoint creates a file in the current folder.
FilterName: The graphics format in which you want to export slides. The specified graphics format must have an export filter registered in the Windows registry. You can specify either the registered extension or the registered filter name. Microsoft Office PowerPoint will first search for a matching extension in the registry. If no extension that matches the specified string is found, PowerPoint will look for a filter name that matches.
Width: The width in pixels of an exported slide.
Height: The height in pixels of an exported slide.


The following java script shows how to export slide into jpg file.

function ExportSlide_Example ()
edoffice.SlideExportSlideToImage(1, "d:\1", "JPG");
