Salesforce (http://salesforce.com) might not be sexy, but it s definitely Web 2.0. Sales and service people can collaborate around their customer bases, using not only the standard Salesforce applications, but also additional web applications built on the AppExchange protocol (http://www.salesforce.com/developer/). Salesforce excels at putting its services in the hands of engineers as well. Both of these are hallmarks of a good Web 2.0 application. To demonstrate Salesforce s Flex API, you will first create an application that shows the contact details of the customers in my Salesforce development database.

Even after taking great care during the coding phase, errors can crop up at run time in your website. Users make typos in page URLs, try to access areas that are restricted, network failures can happen, and so on. As a robust programming practice, you should make provisions to trap all such unexpected errors. In classic ASP, developers used to set custom error pages for web-server level errors (file not found, access denied, and so on) in IIS. This required physical access to the web server. Thankfully, ASP.NET allows you to specify such custom error pages in the web.config file. Let s see how.

Outside .NET, OLE DB is still Microsoft s high-performance data access technology. The OLEDB data provider has been around for many years. If you ve programmed Microsoft Access in the past, you may recall using Microsoft Jet OLE DB 3.5 or 4.0 to connect with an Access database. You can use this data provider to access data stored in any format, so even in ADO.NET it plays an important role in accessing data sources that don t have their own ADO.NET data providers. The .NET Framework data provider for OLE DB is in the namespace System.Data.OleDb. Table 9-3 describes some important classes in the OleDb namespace. Table 9-3. Commonly Used OleDb Classes

not the backup you wish to restore. This might occur in a development scenario where you wish to restore to a backup before major changes were done that you wish to remove. There would be no transaction log involved or required to be involved, therefore restoring to a point in time would not be a valid scenario. This is where the From Device option could be used. By selecting this option and clicking the ellipse to the right, you can navigate to any old backup files. Finally, you can click which of the items in the backup you wish to restore. The default is all files to be selected, as you can see in Figure 7-8. The settings shown will give us a backup that is as fresh as possible (the Most Recent Possible value for the To a Point in Time setting).
