COM objects often use so-called enumerated types to define constants. Unfortunately this concept is not supported by Visual Objects. ADO does this as well.

Vo2Ado has included defines for all the defined constants that are available in ADO.

To be able to check and display enumerated values we have added some support functions to Vo2Ado that help to manage these enumerated types. These functions can be divided into two categories:

1.Functions that return an array with all the different values supported by an enumerated type. These functions return two-dimensional arrays where each line contains of the numeric value followed by its description.
2.Functions that allow to convert enumerated types into strings and vice versa. These helper functions use the arrays that are returned by the first category of functions.
