the infamous "access denied" error image
posted

Hi all, i'm using infragistics ver 6.3 to generate webcharts(Infragistics2.WebUI.UltraWebChart.v6.3,

Version=6.3.20063.53 and UltraChart.DeploymentScenario.Scenario="Session"), and sometimes(extremely random), i get

the infamous "access denied" error image.

Then after a search, I read this kb:
http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.aspx?ArticleID=2041

I've a mixed scenario with a pure asp page with four charts(generate them by calling aspx pages obiouvsly).
Then I try to turn every caching stuff off.

On pure asp page:
response.expires = -1500
response.AddHeader "PRAGMA", "NO-CACHE"
response.CacheControl = "PRIVATE"
response.Buffer=False

On asp.net pages(chart generating pages):
protected void Page_Load(object sender, System.EventArgs e)
        {
            Response.Expires = 0;
            Response.Cache.SetNoStore();
            Response.AppendHeader("Pragma", "no-cache");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);


But still no luck...

Any suggestion?

Here are some addictional question:

1)
There is a way to inercept the "access denied image" via javascript before diplaying it?
I've seen that the output of a "good generated chart" is nearly the same of a "bad generated chart"
i.e.
<img style=''src='ImagePipe.aspx?ChartID=mychart_Base&KxRx=0x04813>

2)
There is a way to change the "acess denied" image with some sort of custom image/custom text?

3)
The last version of UltraWebChart(8.1.20081.1000) may solve the problem?

Thanks in advance

    Hello,

    I've seen this error message often while developing. I am not 100% sure that this covers your case, but could you please try disabling Indexing Services for the folder in your web-application?

    You can take a look at this Microsoft KB article "PRB: Access Denied Error When You Make Code Modifications with Index Services Running" for more information and step-by-step instructions how to proceed.

    Hope this helps.
