re: Handling chart generated images using Chart Http Handler

I store images in RAM memory as follows and I do not have any issues with overwritting or file systems. You can see the web site in action at www.condoscafe.com. I use a lot of charts:

</appSettings>

<system.web>

<!--

</httpHandlers>

<pages>

</controls>

</pages>

</assemblies>

</compilation>

<system.webServer>

</defaultDocument>

</handlers>

</system.webServer>

Hi,

I am trying to use a network path for the images as I have a WebFarm which is loadBalanced using CISCO ACE appliance. The reason I am using a network shared folder is that at times the Chart does not show the PNG images.

The problem with displaying the PNG images in the Web Farm comes when I had initially the web.config setting as shown below.

So I used the network Shared path as per (blogs.msdn.com/.../managing-chart-generated-images-with-chart-image-handler.aspx) , where I have FULL Permissions on EVERYONE, NETWORK Service.

Below is my current setting for the Network shared folder path and I keep getting this error: Invalid temp directory in chart handler configuration

Can someone help. Please reply to soni.sp@gmail.com

Removing "dir" solved my issue with missing folder. It doesn't seem to be mandatory.

skeezmoe,

You probably got your problem resolved but your dir attribute should be something like this

dir=~/Images/Chart

or you need to specify a full path.

Hi,

I want to do a Jquery POST and get a chart using renderControl (which will return HTML attributes) I have successfully done this on WEbforms, However the same with MVC give a empty image. The handler doesn't perform the same in MVC2 3.5. I went near to 50 sites now.

No solutions could resolve this.

I can't use base64encoding as IE6, 7 don't support it.

What I'm trying to do?

I have few data parameteres to be sent (POST) to server and in response get the Chart image as <img> tag along with other attributes I will also append OTHER data all this to be done using JQUERY. No postbacks to be used.
