Sets (of the mathematical variety)

[amcrae]

is there any easy way that i can maintain a set of, say, strings, and be able to access them easily, possibly in order whilst ensuring uniquity (if that is a word)

databases, or arrays? I didn't fully understand what you wanted...

I dont know if this is what you wanted but you could use an Enumeration of strings:

Private Enum NameOfEnum
    String1 = "MyString1"
    String2 = "MyString2"
    String3 = "MyString3"
    String4 = "MyString4"
    String5 = "MyString5"
    String6 = "MyString6"
End Enum

Private Sub Form_Load()
    MsgBox NameOfEnum.String1
End Sub

they are pretty much constant, you cant change them.

I think that the ensuring uniqueness bit would be up to your code, either a 2D array or a UDT Array would do what you want I imagine, as would a collection.

If you bound it up in a class you could have your own rules to ensure uniqueness
