Component Registration

When Excel Builder creates a compone nt, it automatically generates a binary

file called a type library. As a final step of the build, this file is bound with the

resulting DLL as a resource.

When programming with Excel components you m ight need details about

a component. You can use

componentinfo, which is a MATLAB function,

to query the system registry for details about any installed Excel Builder

component.

Obtaining Registry Information

When programming with COM components you might need details about

a component. You can use

componentinfo, which is a MATLAB function,

to query the system registry for details about any installed Excel Builder

component.

Querying the Register for Information About a Component

This example queries the regis try for a component named mycomponent and

a vers ion of 1.0. This co mpo nent has four methods:

mysum, randvectors,

getdates,andmyprimes, two propertie s: m and n,andoneevent:myevent.

The returned structure contains fields corresponding to the most important

information from the registry an d type library for the component.

Info = componentinfo('mycomponent', 1, 0)

Info =

Name: 'mycomponent'

TypeLib: 'mycomponent 1.0 Type Library'

LIBID: '{3A14AB34-44BE-11D5-B155-00D0B7BA7544}'
