File Share Data Processing Extension Sample

  • Artikkeli

FsiDataExtension is a simple data processing extension for the Windows file system. It uses the Microsoft .NET Framework library classes DirectoryInfo and FileSystemInfo to query the contents of any valid network file share. The sample uses the data processing extension interfaces as well as other .NET Framework classes. The naming convention used for the sample is the prefix "Fsi", for File Share Information. This sample is not supported on Itanium-based operating systems.

The SQL Server samples are not installed automatically during setup. For instructions about how to install the samples, see Installing Samples.

Important

Samples are provided for educational purposes only. They are not intended to be used in a production environment and have not been tested in a production environment. Microsoft does not provide technical support for these samples. Sample applications and assemblies should not be connected to or used with your production SQL Server database or your report server without the permission of the system administrator.

Requirements

You should be familiar with Microsoft Visual Studio and either Microsoft Visual C# or Microsoft Visual Basic, and you should have the following installed to use the FsiDataExtension sample:

  • Microsoft Visual Studio 2005 or compatible development environment (for viewing the project files).
  • Microsoft SQL Server 2005, including Reporting Services.
  • Microsoft .NET Framework version 2.0.
  • Reporting Services samples. You can choose to install the samples during SQL Server 2005 setup. For this release, when you choose to install samples, a separate installer is installed on your computer that you can launch to extract and install samples. You can run this installer from the Start menu in the Microsoft SQL Server 2005 program group.
  • A report server that you have permission to access on your network, if you plan to use the sample extension to add additional data processing functionality to your server.

Location

This sample is located in the Extension Samples\FsiDataExtension Sample subdirectory of the Reporting Services samples directory.

For example:

C:\Program Files\Microsoft SQL Server\90\Samples\Reporting Services\Extension Samples\FindRenderSave Sample

Building the Sample

Use the following steps to build the sample.

If you have not already created a strong name key file, generate the key file using the following instructions.

To generate a strong name key file

  1. Open a Microsoft Visual Studio 2005 command prompt. Click Start, point to All Programs, point to Microsoft .NET Framework SDK 2.0, and then click SDK Command Prompt.

    -- or --

    Open a Microsoft .NET Framework command prompt. Click Start, point to All Programs, point to Microsoft .NET Framework SDK 2.0, and then click SDK Command Prompt.

  2. Use the change directory command (CD) to change the current directory of the command prompt window to the folder where the samples are installed.

    Note

    To determine the folder where samples are located, click the Start button, point to All Programs, point to Microsoft SQL Server, point to Documentation and Tutorials, and then click Samples Directory. If the default installation location was used, the samples are located in <system_drive>:\Program Files\Microsoft SQL Server\100\Samples.

  3. At the command prompt, run the following command to generate the key file:

    sn -k SampleKey.snk

    Important

    For more information about the strong-name key pair, see "Security Briefs: Strong Names and Security in the .NET Framework" in the .NET Development Center on MSDN.

To compile the sample using the .NET Framework SDK

  1. Copy Microsoft.ReportingServices.Interfaces.dll from the report server \bin directory into your samples folder.

  2. Issue the following commands to create the sample data processing extension Microsoft.Samples.ReportingServices.FsiDataExtension.dll.

    csc.exe /t:library /out:Microsoft.Samples.ReportingServices.FsiDataExtension.dll *.cs .\properties\*.cs /res:.\properties\Resources.resx  /r:Microsoft.ReportingServices.Interfaces.dll

To compile the sample using Visual Studio .NET

  1. Open the FsiDataExtension solution file (FsiDataExtensionCS.sln or FsiDataExtensionVB.sln) in Visual Studio 2005.

  2. In Solution Explorer, select the FsiDataExtension project.

  3. On the Project menu, click Add Reference.

    The Add References dialog box opens.

  4. Click the .NET tab.

  5. Click Browse, and navigate to find Microsoft.ReportingServices.Interfaces on your local drive. By default, the assembly is located in the ReportServer\bin directory. Click OK.

    The selected reference is added to your project.

  6. On the Build menu, click Build Solution.

Deploying the Sample

After you have completed the previous steps, Microsoft.Samples.ReportingServices.FsiDataExtension.dll can be deployed to a report server or to Report Designer for use in running reports against a custom data source.

To deploy the sample

  1. Copy Microsoft.Samples.ReportingServices.FsiDataExtension.dll to the report server. The default location for report server extensions is C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\bin.

  2. Copy the assembly to Report Designer. The default location for extensions for Report Designer is C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies.

  3. Add the following entry to both the RSReportServer.config and RSReportDesigner.config files under the Data element (the default location of the RSReportDesigner.config file is C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies, and the default location for the RSReportServer.config file is C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer):

    <Extension Name="FSI" Type="Microsoft.Samples.ReportingServices.FsiDataExtension.FsiConnection,Microsoft.Samples.ReportingServices.FsiDataExtension"/>

  4. To enable the generic query designer for the sample data processing extension, add the following entry to the RSReportDesigner.config file under the <Designer> element.

    <Extension Name="FSI" Type="Microsoft.ReportingServices.QueryDesigners.VDTQueryDesigner,Microsoft.ReportingServices.QueryDesigners"/>

For more information about deploying data processing extensions, see Deploying a Data Processing Extension.

To configure code access security for the sample

  1. Open the report server policy configuration file (rssrvpolicy.config). The default location for this file is C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer.

  2. Data processing extensions must be granted full trust. To do so, add the following code group information to the end of the code groups section in the configuration file:

    <CodeGroup class="UnionCodeGroup"
   version="1"
   PermissionSetName="FullTrust"
   Name="FSICodeGroup"
   Description="Code group for my FSI data processing extension">
      <IMembershipCondition class="UrlMembershipCondition"
         version="1"
         Url="C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\bin\Microsoft.Samples.ReportingServices.FsiDataExtension.dll"
       />
</CodeGroup>

  3. If you are using the sample data processing extension in Report Designer, repeat steps 1 and 2 using the Report Designer preview policy configuration file (rspreviewpolicy.config) and the following code group:

    <CodeGroup class="UnionCodeGroup"
   version="1"
   PermissionSetName="FullTrust"
   Name="FSICodeGroup"
   Description="Code group for my FSI data processing extension">
      <IMembershipCondition class="UrlMembershipCondition"
         version="1"
         Url="C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\Microsoft.Samples.ReportingServices.FsiDataExtension.dll"
       />
</CodeGroup>

    The default location for the rspreviewpolicy.config file is C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies.
