[rv2k]

Does anybody know how to generate strings in VB?
Example:

3 letter string
should generate

aaa
aab
...
...
bbb
...
...
zzz

Is this what you want?

For I = 0 To 25
    fChar = 97 + I
    For x = 0 To 25
        sChar = 97 + x
        For y = 0 To 25
            List1.AddItem Chr(fChar) & Chr(sChar) & Chr(97 + y)
        Next y
    Next x
Next I
