Instantiating an EXE Component

You also use the actxserver function to create a server for a component implemented as an executable (EXE). In this case, however, MATLAB instantiates the component in an out-of-process server.

The syntax for actxserver is

• actxserver(ProgID, sysname)
  

where ProgID is the programmatic identifier for the component, and sysname is an optional argument used in configuring a distributed COM (DCOM) system (see the reference page for actxserver).

actxserver returns a handle to the primary interface to the COM object. Use this handle to reference the object in other COM function calls. You can also use the handle to obtain additional interfaces to the object. For more information on using interfaces, see Getting Interfaces to the Object.

Any user interface that is displayed by the server appears in a separate window.

This example creates a COM server application running Excel. The returned handle is assigned to h:

• h = actxserver('excel.application')
  h =
      COM.excel.application
