No can do. Unless you store the values somewhere else (in a string array or something) you can not get the name of the enum variables, nor the values.

A common pactice is to use two extra values, for example
Enum Test
 [Test_Min]=10
 A = 10
 B = 20
 [Test_Max]=20
End Enum

by putting the square brackets around the values, you can hide them from the normal properties list. It's usually used for sequential enums.

Enum is a numbered list of constants.

In the same way that you really can't ask VB to give you a count of how many variables you've used, you also can't ask it to give you how many constants you've used.

For example,

Enum Test
 A = 10
 B = 20
End Enum

is the same as

Const A = 10
Const B = 20

except that they are grouped together under the "object" name of "Test".  This "object" does not have any properties, methods or events so you can't do much with it except use it's "variables."

I've never seen a way to get that, but maybe there's a way using the Scripting object, since it allows you to get other "internal" program stuff.
