The file functions that exist in the normal development environment are not supported by Windows CE instead, new functions have been provided in the API. The Windows CE file system has a host of functions with which to access file-based data. If you think in terms of the OEM developing a household device, you'll see that the functionality is more than adequate. ADO makes it possible to manipulate data in a relational database using the standard SQL to which most Windows developers are accustomed.Įven though the standard database features might sound rather limited, you should remember the kind of application for which Windows CE is designed.
Microsoft has recently released a beta version of ActiveX Data Objects, (ADO) which provides full connectivity to relational databases like Microsoft SQL Server and Microsoft Access. A number of API functions exist to manipulate databases-these are covered in more detail later in this chapter. The records held in a database need not be related for example, you can store contact information in some records and product price details in another record within the same database.
