isprop (COM)

Determine whether input is COM object property

Syntax

tf = h.isprop('propertyname')
tf = isprop(h, 'propertyname')

Description

tf = h.isprop('propertyname') returns logical 1 (true) if the specified name is a property of COM object h. Otherwise, returns logical 0 (false).

tf = isprop(h, 'propertyname') is an alternate syntax.

COM functions are available on Microsoft® Windows® systems only.

Examples

Test a property of an instance of a Microsoft Excel® application:

h = actxserver('Excel.Application');
isprop(h,'UsableWidth')

MATLAB® returns true, UsableWidth is a property.

 

Try the same test on SaveWorkspace:

isprop(h,'SaveWorkspace')

MATLAB returns false. SaveWorkspace is not a property; it is a method.
