ASP.NET Chart Control errors in Event Viewer
- by Richard Reddy
Hi,
I have been using the ASP.NET chart controls for a while on win2k3 (32bit) setups without any issue but have noticed that on our new win2k8 (64bit) box I am getting a warning message showing up in the event viewer from the chart control.
In my web.config file I have the following tag telling the Chart Control where I can store the Temp Files:
<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />
Below is the warning message produced by the control:
Event code: 3005

It's worth pointing out that ALL of the chart images are displayed correctly on the screen so I'm not sure when/where the image not found error is being caused. Is this a 64bit issue?
Thanks,
Rich
