Esri ArcReaderControl
Product Availability
Description
The ArcReaderControl displays the 'data' and 'layout' views of the ArcReader desktop application, together with its Table of Contents. It provides all of the functionality in the ArcReader desktop application except for a toolbar and status bar.
The ArcReaderControl CoClass provides properties, methods and events for managing the general appearance of the control, checking and loading Published Map Files and checking document permissions. The IARControl::ShowARWindow method can be used to display the built in Find, Printer and Magnifier windows and the IARControl::CurrentARTool property can be used to set the current tool to one of the built in navigation, identify or hyperlink tools.
One of the most important aspects of the ArcReaderControl is the notion of its views;the place where data is drawn. The ArcReaderControl has two views, an ARPageLayout view and an ARMap view. Only one of these views can be visible at a time, and is known as the CurrentView. To perform a spatial or attribute search on a ARMap or Layer use the ArcReaderSearchDef object in conjunction the SearchARFeatures or QueryARFeatures methods on the IARMap or IARLayer interfaces.
The ArcReaderConfiguration object can be used to customize the appearance and behavior of the ArcReaderControl and its built in windows.
