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.
I have the same Problem. I am using Infragistics ver 5.1 to generate Webcharts (UltraChart.DeploymentScenario.Scenario="Session"), and sometimes , i get "Access denied" error Image. I try to apply http://support.microsoft.com/kb/329065 , then I disabling Indexing Services at all, but The Problem continue. This Problem is only on Windows Server 2003, it is OK on Windows XP. Can you help me, please?
Thanks in advance.

Hi ouabe3. I doubt I can help much, but I'm sure somebody around here can. Can you provide some more info? Are all 4 charts failing or just some of them? Do they fail 100% of the time? Which deployment scenario are you using? If it's working on XP and not Vista/2003, could it be a permissions issue for the ASP.NET worker process? Maybe it doesn't have access to the file folder (if you're using the FileSystem deployment scenario)?
Hi Tolchinj,
Thank you for your quick answer. All the charts on the page don't fail, just some of them, three, two, one, no one... depending of the time. It 's very weird, because it's difficult to reproduce, the issue happens just sometimes. I use the session deployement scenario and I set the Id of the chart with a kind of guid (different Id per chart). My session state is in proc but I don't use a farm server or the multi processor capabilities. When I look at the link of the picture, everythings seems to be ok and names of the charts are diffferents. I try to use another version of infragistics (7.2 hotfix, 7.3 + hotfix) but I still have this strange issue.
All kind of help would be appreciate.
Regards,
Are you able to fix the issue? I am getting the same error. I am using 7.2 verison.
there are many suggestions given in this thread to solve the problem, so you might want to look through and try some of the proposed solutions. but most importantly, make sure you are using the latest available hotfix for 7.2.
I tried all the solutions and the only working one is to use the file system deployment scenario. It's not acceptable but it is my only solution.
it's hard to tell what is failing. if you want to try something to diagnose the problem, you could set up a test that puts an object like a DataSet into the session, then requests it later from another page.
at some point this object might be cleared from memory; for example if ASP.NET's memory usage gets to a certain point, the process will restart (this is to prevent memory leaks) and everything in the process memory will be gone.
considering the ineffectiveness of all the proposed solutions, I would try to implement vemistemi's workaround: http://forums.infragistics.com/forums/p/5477/26710.aspx#26710
