Create Add-Ins [EA User Guide]

Before you start you must have an application development tool that is capable of creating ActiveX COM objects supporting the IDispatch interface, such as:

·	Borland Delphi

·	Microsoft Visual Basic

·	Microsoft Visual Studio .Net

Create an Add-In

An Enterprise Architect Add-In can be created in four steps:

1.	Use a development tool to create an ActiveX COM DLL project. Visual Basic users, for example, choose File-Create New Project-ActiveX DLL.

2.	Connect to the interface using the syntax appropriate to the language as detailed in the Connecting to the Interface topic.

3.	Create a COM class and implement each of the general Add-In Events applicable to your Add-In. You only have to define methods for events to respond to.

4.	Add a registry key identifying your Add-In to Enterprise Architect, as described in Deploying Add-Ins.
