Creating Custom Administration Tools
Overriding the RenderWebPart Method
Find the version of the RenderWebPart method that the Web Part template provides, and change it to read as follows.
protected override void RenderWebPart(HtmlTextWriter output) { RenderChildren(output); }
Building, Installing, and Testing the Web Part
Compiling and testing the TopSites Web Part involves the same tasks you performed for the Web Parts in 20. Specifically:
1 Use the sn.exe program to generate a strong key file. You need this so that Visual Studio .NET can give your assembly a strong name. 2 Add the strong key file to your project, and enter its name in the AssemblyInfo.cs file. 3 Choose Rebuild Solution from the Build menu and resolve any compilation errors. Repeat as necessary. 4 Copy the resulting DLL into your server s Global Assembly Cache, or into the bin folder for your virtual server. 5 Add a <SafeControl> entry to the <SafeControls> section of the virtual server s web.config file. Remember that the InstallAssemblies tool can perform steps 4 and 5 for you. 6 Make sure the Web Part appears on the Web Part Gallery: New Web Parts (AllItems.aspx) page. If so, select it and click Populate Gallery. 7 Add the Web Part to a Web Part Page (probably a new one) and see what happens.
For more detail on the process of installing and testing a Web Part, refer to the section titled Installing and Testing in 20.

Microsoft Windows SharePoint Services Inside Out
In Summary
This chapter introduced the high-level objects that Windows SharePoint Services provides for performing administrative tasks. It then explained how to use these objects to write a Web Part that displays the top-level sites on a virtual server and creates new top-level sites. This book introduced and explained every major aspect of Windows SharePoint Services, including the browser interface, integration with the Microsoft Office System, advanced design with FrontPage 2003, installation on Windows Server 2003, use with Microsoft SQL Server 2000, complete administration and configuration, and custom programming with Visual Studio .NET. This is an impressive range of topics, and it clearly indicates the strategic position Windows SharePoint Services occupies among Microsoft technologies. Hopefully, this book has magnified your understanding of this important technology and provided exceptional benefit to you and your organization. Good luck with your site, and I hope we meet again.
