I'm attempting to make a application which will scan a site for available usernames.
the way im wanting to do this is so that every .5 of a second or so it adds a letter for example:
time(0):
aaa

time(1):
aab

etc.
anyone know how to do this?

Do you want it to be hardcoded with 3 chars or dynamic like you can change it? Its easier with hardcoding, but Ill try the dynamic way.

Edit

Code: Select all

    Private chars As Char() = "abcdefghijklmnopqrstuvwxyz"
    Private values(3) As Byte
    
    Private Sub Timer1_Tick() Handles Timer1.Tick
        For i = values.Length - 1 To 0 Step -1
            If values(i) + 1 >= chars.Length Then
                values(i) = 0
            Else
                values(i) += 1
                Exit For
            End If
        Next


        Dim res As String = ""
        For Each b As Byte In values
            res &= chars(b)
        Next

        'res is the output string
    End Sub

It might be more effective if you used a list of characters.

[MrAksel]

This method is not even near using 0.5 seconds That was what he asked for.

If you used a list it would not be limited to 3 characters.

This one isn't limited to 3 characters?
I use all the alphabet and all numerical characters in a different one.

I get what he means, but its probably not something much to care about. Just change the '3' in 'values' to the number of chars you want. You can also edit the chars as much as you want, add new, remove some or whatever.
