Hi Shirly,
The MFC ISAPI classes including CHttpServer are not available in Visual Studio 2008. To compile your project please use earlier versions of Visual Studio or you can use Win32 API instead. You can look at the following reference for CHttpServer.

Please note this reference has been updated to the latest release of Visual Studio 2008.
