So, after 3-4 years of inactivity I decided to return to Hawkee, my old account was 'Criminal'.

I'm not sure if this is the right section to post this snippet in, kinda unclear. Also I think it's weird to post a VB snippet without having a close look at the form itself. So I'll provide a screenshot to help you out. It's a single string generator, if you're planning on learning .NET or other languages, I'm sure this tool will be a life safer. You can adjust the length of each string by changing the Convert.ToDecimal(NumericUpDown1.Text) to either a static value like 75, be creative.

Another feature this snippet has is that it automatically copies the string to your clipboard.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim num_characters As Integer
        Dim i As Integer
        Dim txt1 As String
        Dim ch As Integer
        Randomize()
        num_characters = Convert.ToDecimal(NumericUpDown1.Text)
        For i = 1 To num_characters
            ch = Int((26 + 26 + 10) * Rnd())
            If ch < 26 Then
                txt1 = txt1 & Chr(ch + Asc("A"))
            ElseIf ch < 2 * 26 Then
                ch = ch - 26
                txt1 = txt1 & Chr(ch + Asc("a"))
            Else
                ch = ch - 26 - 26
                txt1 = txt1 & Chr(ch + Asc("0"))
            End If
        Next i
        TextBox1.Text = txt1
        Clipboard.Clear()
        Clipboard.SetText(TextBox1.Text)

    End Sub
