Developing Applications 2-3

Scanner Function Overview

The scanner contains a buffer to hold the data from a scan. The

application receives data from the system by one of two methods. The

first method is by the standard keyboard input and second method is by a

special Windows message. See Chapter 4, “Scanning Functions” for

information about the two methods.

Using the Scanners

To use any of the scanners, the application must:

1. Include the code to instantiate the class. For example,

SCANNER.Postamble = “\n\r”

GENERAL.SendScanStatus = false

</SCRIPT>

<BODY>

<OBJECT id=”SCANNER” style ="LEFT: 0px; WIDTH: 0px; TOP: 0px;

HEIGHT: 0px"

classid=clsid: AD3C761C-4BCC-403D-A68D-128ED702A417>

</OBJECT> //Instantiate Class

<OBJECT id=”GENERAL” style ="LEFT: 0px; WIDTH: 0px; TOP: 0px;
