Below is a brute force program to generate any number of Random values of given digits using Visual Basic. The code is specific for given input ( 26 Alphabets and 10 Digits).

Function generate_Number() As Integer

Dim values() As String = {“A”, “B”, “C”, “D”, “E”, “F”, “G”, “H”, “I”, “J”, “K”, “L”, “M”, “N”, “O”, “P”, “Q”, “S”, “T”, “U”, “V”, “W”, “X”, “Y”, “Z”, “0″, “1″, “2″, “3″, “4″, “5″, “6″, “7″, “8″, “9″}

Dim temp As String

Dim i, j, limit As Integer

i = 0

j = 0

limit = 1000 ‘ Number of random values u need

For i = 0 To limit

temp = “”

Dim rand = New System.Random

Dim k As Integer

For j = 0 To 15

k = CInt(Int((35 * Rnd()) + 0))

temp = temp + values(k)

Next

Me.Text = temp

My.Computer.FileSystem.WriteAllText(“C:output.txt”, temp & vbNewLine, True)

Next

End Function
