installer also supports Plug and Play devices for USB Flash Drive

Hardware Support In WindowsXP Tool and hardware support have been improved in lots of ways for the Microsoft?Windows?XP operating system for greater system stability and device compatibility. Windows XP includes Plug and Play support for numerous devices not included in Windows 2000, and enhanced support for USB Drive, IEEE 1394, Peripheral Component Interconnect (PCI), and other buses. WIA Technology Windows Image Acquisition (WIA) provides robust communication between applications and image-capture devices, permitting you to capture images efficiently and transfer these to your pc for editing and use. WIA supports Small Computer System Interface (SCSI), IEEE 1394, USB Flash Disk, and serial digital still image devices. Support for infrared, parallel, and serial still-image devices-which might be attached to standard COM ports-arises from the present infrared, parallel, and serial interfaces. WIA architecture is both a credit card applicatoin-Programming Interface (API) plus a Driver Interface (DDI).
Scanner and Camera Wizard: Using the Scanner and Camera Wizard, you are able to retrieve images from from any of the WIA-enabled devices installed on the machine. The wizard gives a preview page which you could select from several scanning options and adjust image settings. Windows Explorer Program (UI): Windows Explorer extensions for instance My Computer and My Pictures, along with Scanners and Cameras responsible Panel, offer an interface with which you'll want to access WIA devices. Additionally , it affords the option of e-mailing an image, ordering prints via the internet, posting pictures to a Internet site, and saving pictures to CD-R and CD-R/W media (see below for more discussion of Or windows 7 CD mastering technologies). WIA applications: There's 2 main sorts of WIA applications: image editing applications, like Photoshop cs4 and Microsoft Picture It!? and applications for authoring documents that include image data, but cannot edit image data, for example Microsoft Word as well as the Microsoft PowerPoint?presentation graphics program.

The installer also supports Plug and Play devices for USB Flash Drive, SCSI, IEEE 1394 buses, and serial-based digital still cameras. Scripting interface: WIA incorporates a scripting interface, which allows advanced users also it professionals to develop WIA applications when using the Microsoft Visual Basic?development system and other scripting languages.
You'll find four system dialog objects: the scanner common dialog object, the still camera common dialog object, the recording camera common dialog object, and the device selection dialog object. Represented inside the UI as dialog boxes, these permit you to preview thumbnails and full-sized pictures; crop, scan, and hang up scan properties of an picture; view picture information; view live or recorded digital video and capture frames in the stream; select WIA devices; and hang WIA device properties. Device object: When the WIA device driver commences, celebrate something component referred to as device object. You will discover four kinds of device objects: WIA mini driver, WIA generic flatbed scanner, and WIA generic digital still camera and WIA generic camcorder object. WIA Device Manager: When a credit card applicatoin first communicates which has a device, the WIA Device Manager detects the many devices, creates these devices objects, establishes the url between your application and the device objects, and retrieves and sets device properties. Digital Audio Devices and Technologies To support digital audio devices, Or windows 7 uses the Windows Driver Model (WDM) audio architecture, which enables the operating system to control multiple audio streams simultaneously.
