External Program Interfaces : Using COM Objects in ABL : Accessing COM object properties and methods

Accessing COM object properties and methods

ABL supports direct access to COM object properties and methods. This support extends the syntax used for widget attribute and method references. Other than syntax validation, ABL does no compile-time checking of property and method references. All other property and method validation occurs at runtime, when all COM objects are (dynamically) instantiated. Thus at runtime, ABL dispatches each property or method reference to the COM object for evaluation and execution.
* Property and method syntax
* Specifying options for properties and method parameters
* Restrictions on property and method references
