PictureBox and large image error

[Simone]

Hi

I have this error on a Report with a PictureBox and large images (> 2MB) :

An error has occurred while processing PictureBox 'Foto1': Unable to create the store directory. (Exception from HRESULT: 0x80131468) 

The error appears only on the hosted site and not on my PC.

Target Framework: 3.5
Reporting version: Q3 2012 -  6.2.13.110

Attached the screenshot of the error.

Thanks in advance
Simone

Hi

I am trying to use reportProcessor instead that ReportViewer, saving directly in PDF... but same error :((

...
...
Dim reportProcessor As New Telerik.Reporting.Processing.ReportProcessor()
Dim result As RenderingResult = ReportProcessor.RenderReport("PDF", instanceReportSource, Nothing)

Response.Clear()
Response.ContentType = result.MimeType
Response.Cache.SetCacheability(HttpCacheability.Private)
Response.Expires = -1
Response.Buffer = True

Response.AddHeader("Content-Disposition", "attachment; filename=" & dr("IdImmobile") & ".PDF")
Response.ContentType = "application/octet-stream"
Context.Response.BinaryWrite(result.DocumentBytes)
Context.Response.End()

The problem is always the file size....

Any idea ??

Thanks
Simone

Hello,

It seems that the Reporting engine cannot create a folder in the Isolated Storage in order to temporary store the image while it is being processed. This might be caused by insufficient privileges for the process to read and write in the Window's Temp folder for the process and in the Isolated Storage.

To solve the problem you have to either grant permissions for the application to access these locations or configure the Telerik Reporting Cache to use only Memory cache or File cache with an explicitly specified path which has the corresponding read/write permissions. You can check how to configure the cache from the Cache Management section in the documentation.

Hi Chavdar 

I also tried with this configuration before write this post:

<Telerik.Reporting>
    <Cache provider="File">
      <Providers>
        <Provider name="File">
          <Parameters>
            <Parameter name="BasePath" value="D:\Inetpub\webs\gestionehouseimmobiliareinfo\Public\Temp" />
          </Parameters>
        </Provider>
      </Providers>
    </Cache>
  </Telerik.Reporting>

but same error... :(

I looked via ftp to the temp folder during report rendering and I can confirm you that tmp files are created there

Same situation with Cache provider="Memory"

Attached a screenshot of filezilla, so you can view  the content of the temp folder

Thanks

Hello,

You have to upgrade to the latest version of Telerik Reporting (v7.1.13.612) in order the configuration setting to be used by the processing engine as well. Give it a try and let us know whether it solves the issue.

Hi

v7.1.13.612 needs NET Framework 4.0 and in this moment I can't upgrade the entire project from 3.5 to 4 (due provider limitation also)...

So I'll convert this report with Crystal Report... :((

I'm going to do some test with trial version of Telerik Reporting during next days, and I'll tell you the result

Thanks

Hi there

First attempt with v.7.0.13.220 (NET 3.5), but same error...

Application recompiled with Net 4.0 and telerik rerporting 7.1.13.612 (trial version)

Now I have this error:

Security Exception

Hi,

Most probably your application is running in Medium trust if you are receiving this error. In Medium trust configuring the Telerik Reporting section is not possible due to security restrictions.

If this is the case, there is no way to change the Reporting Cache provider and the only option is to grant permissions for the application to access either the Window's temp folder or the IsolatedStorage. You can also consider to run the application in Full trust as some of the product's features are not available in Medium trust. For more information, please check the Medium Trust Support help article.
