Concepts – WD802Term ActiveX

Drop-in components are tools that are added to your programming environment "tool kit". Only the ActiveX variety are widely compatible with almost all development environments. When you use drop-in components in your program you will follow the standard object-oriented programming paradigm that uses properties, methods, and events to implement the functionality of the drop-in component.

Properties are the various configuration variables used by the drop-in component. An example of a property is the ServerActive setting.

Methods are function calls used to issue commands and access features of the drop-in component. An example of a method is sending an Input command to the terminal.

Events are function definitions placed in your application’s source code. The function definitions in your source code are called Event Handlers. The skeleton structure of the event handler’s source code is automatically generated. The code in the Event Handler is called ("fired") by the drop-in component when a specific event occurs. An example of an event is when a terminal returns data and the OnTermData event is fired.

The details of how to access Properties/Methods/Events varies between development platforms. Details of how it works in some of the most popular

platforms is illustrated in the samples included with the RF Utilities CD or available for download from our website at www.barcodehq.com

Properties – WD802Term ActiveX

Properties are the various configuration variables used by the WD802Term control. They are directly assignable in your application (eg. "WD802term.ServerOn = true") and can be set in your development environment’s object browser.

Note that your development environment may show more properties for the WD802Term control than are listed here. This is normal. You may ignore pro-

perties you see listed in your development environment that are not listed here.
