hello rajesh,
ru able to execute the above code successful !.
if u want to access the ms-powerpoint so,
HWSL is used to make the Microsoft PowerPoint 97(-2003) file format by pure Java. It supports read and write capabilities of some, but not yet all of the core records.

follow the example and observe the imports.

this code is for creating a PowerPoint presentation. For this we are creating the object of SlideShow after that we are creating an object of slide and an object of file output to create a .ppt file .

import org.apache.poi.hslf.HSLFSlideShow;
import org.apache.poi.hslf.model.Slide;
import org.apache.poi.hslf.usermodel.SlideShow;
import java.io.*;
public class createNewPersentation
{
public static void main(String str[])
{
try{
SlideShow slideShow = new SlideShow();
Slide slide = slideShow.createSlide();
FileOutputStream out = new FileOutputStream(“slideshow.ppt”);
slideShow.write(out);
out.close();
}catch(Exception e){}}
}

Hi Vijay!

Can you give an example how to read a doc file picture. Is there a difference if the document is inserted in Microsoft Word BMP, JPEG, GIF files, or other.
Waiting for reply. Thank you.
