a scanner is just another input device. you will need an API for the scanner. If one exists it would come from the vendor.

u r right . but i wan know the way windows gets the installed scanners list then to get the data from selected device

 

[jmeckley]

way windows gets the installed scanners list

probably the same way it gets the mouse, printers, key board, and any other devices. via the driver.

then get the data from selected device

this is specific to the driver.

If the vendor allows for programmatic access then you will need the vendors API.

I believe MS has already an API (WIA) for this:
