7 ActiveX and DDE Support

7-6

MATLAB ActiveX Client Support

In order to use an ActiveX component with MATLAB or with any ActiveX

client, you first need to consult the documentation for that object and find out

the name of the object itself (known as the ProgID), as well as the names of the

interfaces, methods, properties, and events that the object uses. Once you have

this information, you can integrate that object with MATLAB by using the

ActiveX client support.

Using ActiveX Objects

You create an ActiveX control or server in MATLAB by creating an instance of

the MATLAB

activex class. Each instance represents one interface to the

object.

Note This book uses ActiveX to refer to the generic ActiveX control/server

and activex to refer to the MATLAB class/object.

Creating ActiveX Objects

There are two commands used to create activex objects initially.

Manipulating the Interface

Once you create an activex object that represents an interface, you can

manipulate it by invoking methods on the object to perform various actions.

These methods are implemented for the

activex class.

actxcontrol

Creates an ActiveX control

actxserver

Creates an ActiveX automation server

Method Description

delete

Deletes an activex object

get

Gets a property value from an interface or displays a

list of properties
