Glossary Item Box

You can use ActiveReports 6 on Windows Azure in full trust or partial trust modes, but with limitations on some of the features.

Note: If you see an evaluation banner when deploying your ActiveReports 6 project, you shoud use the Web Key Generator utility to create the Web Key and integrate the license information into your project.

Full Trust Feature Limitations

Exporting

  • Rtf and Text filters are not supported on Windows Azure.

Partial Trust Feature Limitations

  1. Exporting limitations
    • Rtf, Text, Tiff and Excel filters are not supported in Azure partial trust.
    • Digital signatures for the Pdf export filter are not supported.
  2. The Picture control does not support metafiles in Azure partial trust.
  3. Chart and Custom controls with the ImageType property set to metafiles also require Full trust.
  4. The OleObject control requires Full trust.
  5. Scripting requires Full trust, so if you need to use code in reports under partial trust, use code-based reports rather than RPX format.
  6. The OLE DB data source is not supported in Azure partial trust.

Recommended Development Environment for Azure Partial Trust

ShowTo set up Partial trust in an Azure Web Role Application

  1. In Solution Explorer, expand the Roles folder of your Azure project and double-click the role reference WebRole1.
  2. On the Configuration page that appears, select Windows Azure partial trust under .Net trust level.
  3. In Solution Explorer under WebRole1, double-click Web.config.
  4. In the Web.config file that opens, remove the <System.Diagnostics> tag.
  5. In Solution Explorer under WebRole1, double-click WebRole.cs.
  6. In the WebRole.cs file that opens, remove or comment the following line as the diagnostics library does not support partial trust callers: 
    DiagnosticMonitor.Start("DiagnosticsConnectionString")

ShowTo set up Partial trust in an Azure Worker Role Application

  1. In Solution Explorer, expand the Roles folder of your Azure project and double-click the role reference WorkerRole1.
  2. On the Configuration page that appears, select Windows Azure partial trust under .Net trust level.
  3. In Solution Explorer under WorkerRole1, double-click App.config.
  4. In the App.config file that opens, remove the <System.Diagnostics> tag.
  5. In Solution Explorer under WorkerRole1, double-click WorkerRole.cs.
  6. In the WorkerRole.cs file that opens, remove or comment the following line as the diagnostics library does not support partial trust callers: 
    DiagnosticMonitor.Start("DiagnosticsConnectionString")

ShowTo set up a local storage resource in a Web Role partial trust Application

  1. Open the service definition file (ServiceDefinition.csdef) and add the following tag after<WebRole name=”WebRole1”>: 
    Paste into ServiceDefinition.csdef after <WebRole name=”WebRole1”> Copy Code
    <LocalStorage name="WebRoleStorage" cleanOnRoleRecycle="true" />
  2. To export to PDF, paste the following code into Default.aspx.cs to the button_Click event:
    Paste into Default.aspx.cs to the button_Click event Copy Code
    NewActiveReport1 rpt=new NewActiveReport1 (); 
rpt.Run ();
DataDynamics.ActiveReports.Export.Pdf.PdfExport pdfe = new DataDynamics.ActiveReports.Export.Pdf.PdfExport (); 
string webrolestorageName = "WebRoleStorage"; 
string webRoleFileName = "Test.pdf"; 
LocalResource lr = RoleEnvironment.GetLocalResource (webrolestorageName);
string path = lr.RootPath + webRoleFileName; 
pdfe.Export(rpt.Document, path);
  3. You can find the exported PDF file at the following location: C:\Users\stduser\AppData\Local\dftmp\s0\deployment (0)\res\deployment (0).CloudService1.WebRole1.0\directory.

    Note: The file is available only at the application runtime.
