ARCOBJECTS OMD PDF

Net with VS Please take this repository as a memo to walk you through the AO setup, debug and development This will create a template of a button control for ArcMap. You should be able to find a cs file with name "Button1. Please replace this file with the on at here. Before we build the button control, open Soultion Explorer of your VS , right-click on the project name and choose properties.

If one interface is inherited by another interface, the members of the initial interface are also members of the inheriting interface. See the following illustration: Interface inheritance is used extensively to, in effect, add functionality to existing interfaces.

Although the rules of COM dictate that an interface signature - once deployed - cannot change, an interface can be created that inherits from the original interface. For example, the IEditor2 interface extends the IEditor interface with additional members. See the following: Interfaces defined in other libraries - If the interface name is prefixed with a library name - such as, esriSystem. IName - the interface is inherited from a library other than the one implementing it. The library name reflects the library in which the interface is defined.

On the following illustration, the Name abstract class, an object in the GeoDatabase library, is shown. As shown by the library name prefix, the interface implemented by Name is actually defined in the System library.

Optional interfaces - Some interfaces can be inherited optionally by other classes. These are designated by the prefix Optional. See the following illustration: As a developer, if you intend to utilize an optional interface, verify that the interface was implemented by the object with which you are working.

Interfaces implemented in select instances - Some classes have varying implementations instead of having multiple classes that inherit from a single base or abstract class. In these cases, certain interfaces are implemented in select instances. For example, the RasterDataset class can be instantiated by different workspace classes depending on the type of data being accessed.

See the following illustration: Interfaces implemented in select instances are designated with the prefix Instance. Outbound interfaces Outbound interfaces, also known as event interfaces, provide notification when a certain event occurs. Interaction with the members of an outbound interface requires that another object exists to catch the event occurrences this is commonly referred to as an event sink. Event sinks have code that responds when certain events occur, for example, an editing operation.

The Helper class is an artificial coclass that solves the Visual Basic problem with multiple outbound interfaces on an object. See the following illustration: Interface members The members of an interface include its properties, which specify the state of an object, and its methods, which perform some action. When an object is passed by reference, an association is formed between the two objects. This is advantageous because an object can be reused in many associations, using less memory space.

Its inheritance relationship to all other name objects indicates that they each implement the IName interface as well. This usage guarantees that the new FeatureClass object is properly created and includes all necessary information.

When you use an application, such as ArcMap, usually you are looking at or working with ArcObjects. Examples of the core assemblies include Carto, Display, Map, and Geodatabase. Object model diagrams Each assembly consists of ArcObjects that can be diagrammed based on their class relationships. These diagrams are referred to as object model diagrams OMDs.
