在事件查看器ASP.NET图表控件的错误

我一直使用ASP.NET图表控件上WIN2K3一段时间（32位）设置没有任何问题，但已经注意到，我们的新win2k8（64位）箱我越来越显示出从事件查看器一句警告信息，图表控件。

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.

在我的web.config文件中，我有以下标记告诉图表控件在那里我可以存储临时文件：

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\;" />

下面是由控制产生的警告消息：

Below is the warning message produced by the control:

这是值得指出的是所有图表图像的正确显示在屏幕上，所以我不知道何时/何图像未找到错误正在造成的。这是一个64位的问题？

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?

谢谢，
