Hi,

I am using quickpdf Active-x with PHP and sometimes I am getting the error like

Uncaught exception 'com_exception' with message 'Failed to create COM object 'QuickPDFAX0718.PDFLibrary':CoInitialize has not been called.' in.

The code I am using is as follow:

$this->objqp = new COM("QuickPDFAX0718.PDFLibrary");

$qpkey = $this->objqp->UnlockKey("*****************");

Please told me the appropriate solution for that.

Hi!

You don't read other posts...? ;-)
http://www.quickpdf.org/forum/tquickpdfcreate-crash-if-coinitialize-not-called_topic2049.html - http://www.quickpdf.org/forum/tquickpdfcreate-crash-if-coinitialize-not-called_topic2049.html
If you're using Google with this string "CoInitialize has not been called" you'll get the answer immediately:
Call CoInitialize when your program starts and CoUnitialize when it terminates.
It depends on your programming language... in C++ it should be in InitInstance and ExitInstance.
BTW: You should update at least to last 7-version 7.26 or try the newest 8-beta soon where the "CoInitialize-behavior" will be fixed.

Cheers and welcome here,
Ingo

But I was not finding any solution for that.

Thank for reply

Hi!

So you know what to do.

Use the co-syntax and it will run as you want it.

And up from the newest 8.xx beta you won't have to care about these issues ;-)

Cheers, Ingo

We have added a whole lot of code to the 8.14 beta 1 release that should overcome the the CoInitialize problem. Beta testers are very welcome.
