The IDLcomIDispatch::SetProperty function method is used to set properties for the COM object that underlies an IDLcomIDispatch object. The COM object's property names are represented as IDL keywords to the SetProperty method, and property values are treated as IDL keyword values. See Chapter 4 in the External Development Guide for details.
Any property listed under IDLcomIDispatch Properties that contains the word "Yes" in the "Set" column of the properties table can be set using this method. To set the value of a property, specify the property name as a keyword set equal to the appropriate property value.
