I need help with imagegrabwindow() ...

[jonaofarc]

Basically Iam trying to use the imagegrabwindow() however when this scripts run were does it save the PNG to? nothing seems to happen and no file is added in the files directory.

 

 

<?php

$browser = new COM("InternetExplorer.Application");

$handle = $browser->HWND;

$browser->Visible = true;

$browser->Navigate("http://www.libgd.org");

 

/* Still working? */

while ($browser->Busy) {

    com_message_pump(4000);

}

$im = imagegrabwindow($handle, 0);

$browser->Quit();

imagepng($im, "iesnap.png");

?>

iesnap.png?

 

 

 

You aren't trying to run that under linux are you?

 

 

Also, you might have to enable the Apache service to interact with the desktop if you're running that under Apache with PHP as a module.

no I ran in on windows XP but nothing happens ..

 

 

how do you allow ? or what code to I put in the httpd.conf to allow interaction with the desktop?

[corbin]

Windows Logo + R.

Type in "services.msc" and hit enter.

Find the Apache service in the list that comes up.

Right click on it and hit properties.

Click on the "Log On" tab.

Click the "Allow service to interact with desktop" box.

corbin.. any ideas where can I find the saved images? I did as you asked regarding the apache

Hrmmm, I guess check if stuff is failing for some reason or other.

 

 

First, I would change the error_reporting and display_errors.

 

error_reporting(E_ALL);

ini_set('display_errors', '1');

 

 

Then, you could check the return of the functions to make sure neither of them are failing.

 

 

$im = imagegrabwindow($handle, 0);

$browser->Quit();

if($im === FALSE) {

    echo 'Error grabbing window shot.';

}

else {

    if(!imagepng($im, "iesnap.png")) {

        echo "Error calling imagepng().";

    }

}

Fatal error: Call to undefined function imagegrabwindow()

Does php_gd2.dll exist in your extensions folder?

 

 

If so, just add

 

extension=php_gd2.dll

 

In php.ini.
