How Do I Set a Value of an Enumerated Type Parameter of a COM Object? (Magic xpa 3.x)
An enumerated type is a type whose legal values consist of a fixed set of constants. Examples would be days of the week, months of the year, or something like types of paragraph alignments. Often in COM objects, when you have a choice between several things, you pass an integer to make a choice.
Exactly what integer stands for which choice is something you need to look up in the documentation for the COM object, or you can experiment and see what happens.
