[SOLVED] Speed and script issues with HTML Active Reports

Greetings Everyone,

I am getting an error when running an AHTML report out of a self-guided report I made earlier:

"Stop running this script?

"A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer might become unresponsive."

Also, the report itself takes a very long time to run. The other formats (HTML, Excel, PDF, etc.) come up much faster with no errors.

Are there special settings that one needs on their browser to assist with this?

Thank you for your time,
Steven Warner

Run a small Active HTML report and view the source. You may be surprised by how much JavaScript there is. IE needs to digest this JavaScript before rendering the page.

The warning pop-up gives the user a chance to stop rendering if it's taking too long. Some pages my trigger the pop-up more than once.

To prevent this pop-up, you can modify the registry:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles\MaxScriptStatements set to 0x04c4b400


This value increases the number of Javascript statements that is allowed to execute before the warning pops up. To completely avoid the dialog try 0xFFFFFFFF.

Read this Microsoft support article: http://support.microsoft.com/kb/175500 where you can "fix it for me".

Thank You Francis.

I was afraid of that. Is there any way to improve the performance of larger AHTML reports? They are a fantastic way of presenting data except their performance puts users off.

Thank you again for your time,
Steven Warner

Try Active Cache: 
ON TABLE SET WEBVIEWER ON
ON TABLE SET CACHELINES <n>

Where 'n' is set to the number of lines of the first five or so pages.
