Enum, Type and UDT

[Sforster]

Could anyone explain in a couple of sentences the purpose of using Enum and Type (or would it take a lot longer) and what UDT is !!!

Thanks for any help

UDT (User-defined Data type) is the result of a Type statement. You create a UDT by putting together fields of the standard object types in one group and treating it like one object. For example, you have a program about bugs (insects, spiders, etc.) and their individual characteristics. You could have 15 different fields describing them, or you could put those 15 fields into a UDT and have one object. Instead of moving around each of the 15 fields, you just move one UDT object. An Enum is a UDT kind of object that contains a bunch of related constants instead of data fields. I see no use for Enum, but I use UDTs all of the time.

Hi,
Enums have their use!! Using Enum as constants, you can use those in function parameters so that when the function is called, you get a drop-down list of available options for the values of that parameter. (like in the msgbox function where you have vbAbort,vbOk etc...).

I like them anyway as it saves having to remember values!!

I stand corrected. You learn something new every day, especially here!
