    I want to use this code

    Code:
          Dim num_characters As Integer
        Dim i As Integer
        Dim txt1 As String = ""
        Dim ch As Integer
        Randomize()
        num_characters = Convert.ToDecimal(70)
        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
   
        Try
            Dim p1 As Process = Process.GetProcessesByName(Process.GetCurrentProcess().MainModule.ModuleName.Replace(".exe", "").ToLower.ToString)(0)
            SetWindowText(p1.MainWindowHandle, txt1)
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    but its not working, why is that? O_O

    More simple way... Make sure you use this... Imports System.Text and place this code in your Form Load Event.

    Code:
            Dim str As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
        Dim r As New Random
        Dim sb As New StringBuilder
        For i As Integer = 1 To 8
            Dim idx As Integer = r.Next(0, 35)
            sb.Append(str.Substring(idx, 1))
        Next
        Me.Text = sb.ToString
    EDIT: If you want lower case letters replace the string characters to lower case, or for a mix of upper and lower it should look like this...

    Code:
    "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789"
