Fatal error: Uncaught exception 'com_exception' with message. while converting ppt to jpg

Question

When I run blow code:

/*** PPT to Image conversion ***/
$ppt_file = 'E:\wamp\www\temp/a.pptx';
$app = new COM("PowerPoint.application") or die("Unable to instantiate PowerPoint");
$app->Visible = true;
$app->Presentations->Open($ppt_file); 
$app->Presentations[1]->SaveAs("E:/tmp/outdir",18);
$app->Presentations[1]->Close();
$app->Quit();
$app = null;

It gives me one exception :

Fatal error: Uncaught exception 'com_exception' with message 'Source: Microsoft Office PowerPoint 2007
Description: PowerPoint could not open the file.' in E:\wamp\www\temp\video_conversion.php:107 Stack trace: #0 E:\wamp\www\temp\video_conversion.php(107): variant->Open('E:\wamp\www\tem...') #1 {main} thrown in E:\wamp\www\temp\video_conversion.php on line 107

I am unable to figure out what is the problem.

Have you ruled out a permission issue by opening the directly from your code? — Paul B., May 22 '12 at 13:09
Did you find a solution to this? I am having a similar problem. — Shadrack Orina, Jul 21 '12 at 09:21

This is kind of issue is due to the following factors.

PHP.ini settings
Folder Permission
allow open is not enabled in the server
allowed upload size

Within your error, you see the following message: PowerPoint could not open the file.' in E:\wamp\www\temp\video_conversion.php:107

Does the PHP user have permissions to the file E:\wamp\www\temp/a.pptx?

Try correcting your slashes: E:\wamp\www\temp\a.pptx as / normally refers to an option or argument.

At the end of the day, it appears to be a permissions error, a location issue or alike which is preventing access to that file. Can you open the file with fopen or file_get_contents?

The slash is just a typo. Lemmy try with file get contents and tell u what happens. – Shadrack Orina Jul 22 '12 at 03:52
Any luck with file_get_contents? – Mike Mackintosh Jul 27 '12 at 15:15

Try this with com class:

COM class Reference: - http://us2.php.net/manual/en/class.com.php

<html>
<head>
<title>ShotDev.Com Tutorial</title>
</head>
<body>
<?
    $ppApp = new COM("PowerPoint.Application");
    $ppApp->Visible = True;

    $strPath = realpath(basename(getenv($_SERVER["SCRIPT_NAME"]))); // C:/AppServ/www/myphp

    $ppName = "MySlides.ppt";
    $FileName = "MyPP";

    //*** Open Document ***//
    $ppApp->Presentations->Open(realpath($ppName));

    //*** Save Document ***//
    $ppApp->ActivePresentation->SaveAs($strPath."/".$FileName,17);  //'*** 18=PNG, 19=BMP **'
    //$ppApp->ActivePresentation->SaveAs(realpath($FileName),17);

    $ppApp->Quit;
    $ppApp = null;
?>
PowerPoint Created to Folder <b><?=$FileName?></b>
</body>
</html>

Or try this :

$powerpnt = new COM("powerpoint.application") or die("Unable to instantiate Powerpoint");

$presentation = $powerpnt->Presentations->Open(realpath($file), false, false, false) or die("Unable to open presentation");

foreach($presentation->Slides as $slide)

{

    $slideName = "Slide_" . $slide->SlideNumber;

    $exportFolder = realpath($uploadsFolder);

    $slide->Export($exportFolder."\\".$slideName.".jpg", "jpg", "600", "400");

}

$powerpnt->quit();
