Device Driver SystemDevice Driver System
Device driver Links an operating system and a device
Built-in Drivers vs. Installable Drivers Built-in drivers are installed by the platform manufacturer Installable drivers are third-party peripheral devices that
end users can connect to a windows CE-based platform Native Drivers vs. Stream Drivers
All of the device drivers managed by GWES are native device drivers
Device manager loads stream interface drivers when the system boots, if those drivers are listed in the registry
Monolithic Drivers vs. Layered Drivers Monolithic drivers implement interface directly in terms of
actions on the device they control Layered drivers separated the implementation into two
layers

Can provide access to a floppy diskette, a hard drive, a flash file system on a PC Card, or to other external storage devices
File-shadowing mechanism Allows a file to be stored both in RAM and ROM.
Differences from other Windows file systems No letters assigned to file systems No concept of current directory No support for overlapped I/O All files stored in Ram are automatically compressed

Registry Provides a common repository for system settings,
application data, and user preferences Resides in RAM, if not present in RAM, the registry can
be reloaded from persistent storage or rebuilt from ROM Registry functions specific to Windows CE
Property Database Provides a lightweight database management system Accessible using a new set of Win32 API functions
specific to Windows CE Data stored in a flat model Accessible to ActiveX Data objects for Windows CE
(ADOCE) Supports multiple volumes on installable file systems

Common practice for developing international software: Use a few target locales for initial development and testing Resource Localization: Strict or Non-strict
Translation Tips Avoid using vague words, colloquialisms, jargon, acronyms,
and abbreviations Use good grammar Avoid dynamic concatenation of different strings Avoid hard-cording file names in a binary files Avoid including text in image and icons
