Previous Comments: ------------------------------------------------------------------------ [2020-02-06 17:54:36] cmb@php.net First, a com_exception with the message "Source: Unknown Description: Unknown" is thrown when a dispatch exception occurs, but the automation server does neither provide a source nor a description. That means this is a rather generic error message, which does not tell anything about the root cause. Likely, the different commenters here have different issues. Regarding the OP: Microsoft Virtual Server had its last release in 2007, so I assume this issue is obsolete. Am I wrong? > the script runs ok when i start it from a command window. > but it gives me this error when i try to run it from a php page: This hints at some environmental issues (maybe insufficient permissions). Regarding the imagegrabwindow() example from the docs: while I don't get any error or exception, I get a completely black image. A quick look at the implementation of imagegrabwindow() shows that the error handling should be improved. And I think the error handling of this particular com_exception should also be improved, but that is tracked in bug #51904. ------------------------------------------------------------------------ [2011-08-10 08:22:26] pe dot dolenc at gmail dot com Hello guys, I've had similar problems trying to start application in the background, but always getting the Source: Unknown error. For me the cause was, that backslashes weren't escaped, so please double check your code. ------------------------------------------------------------------------ [2009-05-27 02:26:15] jstel at 126 dot com i get same error . the error code is Fatal error: Uncaught exception 'com_exception' with message '<b>Source:</b> Unknown<br/><b>Description:</b> Unknown' in D:\xampp\htdocs\snap\snap.php:4 Stack trace: #0 D:\xampp\htdocs\snap\snap.php(4): unknown() #1 {main} thrown in D:\xampp\htdocs\snap\snap.php on line 4 my source code is from demo of http://cn.php.net/manual/en/function.imagegrabwindow.php <?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"); imagedestroy($im); ?> ------------------------------------------------------------------------ [2008-10-04 23:05:16] pykker at gmail dot com I tried on Windows Vista SP1, PHP 5.2.1 and getting the same error.
