MATLAB课程：代码示例之Programming（六）

Call COM Objects

Access COM components and ActiveX® controls from MATLAB®

The Microsoft® Component Object Model (COM) provides a framework for integrating reusable, binary software components into an application. Because components are implemented with compiled code, the source code can be written in programming languages that support COM. Upgrades to applications are simplified, as components can simply be swapped without the need to recompile the entire application. In addition, a component's location is transparent to the application, so components can be relocated to a separate process or even a remote system without having to modify the application.

Alternatively, consider using the Microsoft .NET Framework.

MATLAB supports COM and the .NET Framework integration on the Microsoft Windows® platform only.

iscom	Determine whether input is COM or ActiveX object

isprop	Determine whether input is COM object property
get	Get property value from interface, or display properties
set	Set object or interface property to specified value
addproperty	Add custom property to COM object
deleteproperty	Remove custom property from COM object
inspect	Open Property Inspector
propedit	Open built-in property page for control
fieldnames	Field names of structure, or public fields of object

ismethod	Determine whether input is COM object method
methods	Class method names
methodsview	View class methods
invoke	Invoke method on COM object or interface, or display methods

isevent	Determine whether input is COM object event
events	List of events COM object can trigger
eventlisteners	List event handler functions associated with COM object events
registerevent	Associate event handler for COM object event at run time
unregisterallevents	Unregister all event handlers associated with COM object events at run time
unregisterevent	Unregister event handler associated with COM object event at run time
