Catastrophic failure when trying to perform HTMLtoPdf Conversion

I have downloaded a trial version of syncfusion and am attempting to create a small little HTML2PDF Converter. I''ve copied the source from another email in here but everytime I excute the page I get the following stackdump and am unsure where I should start looking to solve the problem?:

Server Error in ''/'' Application.

Hi Jason,

I am afraid. I was unable to reproduce the issue when i tried running the sample with the mentioned version.

Here is a sample for your reference.

HTML_TO_PDF_CS_2005.zip

Could you please run this sample and let me know if the problem still exist.

Thanks
Dhivya.

Thanks Dhivya

I was able to get the code working from a new IIS application.

But when I attempted to use the code in an existing assembly after clicking the button to convert the browser would constantly sit there awaiting a response from the server. It appears as though the server thread just goes idle.

My test was as follows:
Copy your code to my existing project.
Add assembly references two dll''s provided.
Execute code.

I would really like to solve why this is so, as it prohibits me from recommending the product for purchase as I need the functionality integrated into our existing code.

Are there any items that may interfere with the operation of SyncFusion Essential PDF?

The server is running Windows 2003 SP1.

Hi Jason,

I am afraid.I am not able to reproduce the issue. Could you please do the following and let me know if the problem still exist?

1) Add to the @Page directive AspCompat="true" attribute to the page where we want to perform html to pdf convertion.

2) Reference the "AxInterop.dll and SHDocVw.dll" assembly to the project.

Thanks,
Dhivya.
