Password Generator

Submitted by admin on Monday, April 29, 2013 - 00:06.

This password generator is based on the class created by Obviex. The generator can create a unique password that does not include ambiguous character. It can create alphanumeric and special character password. The password will always start with a letter. The best part here is that you can choose if you want to include a special character or numeric value by simply adding the pre-defined constant in the array. This can be done by using the following code:

Dim charGroups As Char()() = New Char()() _
{ _
	PASSWORD_CHARS_NUMERIC.ToCharArray(), _
	PASSWORD_CHARS_LCASE.ToCharArray() _
}

Other values are PASSWORD_CHARS_UCASE and PASSWORD_CHARS_SPECIAL. Here’s an example code that calls the RandomPassword class.

Imports System.Data.OleDb
 
Public Class frmGenPass
    Dim cnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Data.mdb;"
 
    Private Sub btnGenPass_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenPass.Click
        Dim I As Integer
        Dim strPass As String
        Dim strSQL As String
 
        For I = 1 To 10
            strPass = RandomPassword.Generate(6, 6)
 
            Try
                ListBox1.Items.Add(strPass)
 
                strSQL = "INSERT INTO Users ([Password]) VALUES ('" & strPass & "')"
 
                ExecNonQuery(strSQL)
            Catch ex As Exception
                Debug.Print(ex.Message)
            End Try
        Next
    End Sub
 
    'Execute Non Query
    Public Sub ExecNonQuery(ByVal strSQL As String)
        Dim conn As OleDbConnection
        conn = New OleDbConnection
 
        Try
            With conn
                If .State = ConnectionState.Open Then .Close()
 
                .ConnectionString = cnString
                .Open()
            End With
 
            Dim cmd As OleDbCommand = New OleDbCommand(strSQL, conn)
 
            cmd.ExecuteNonQuery()
 
        Catch ex As OleDbException
            MsgBox(ex.ToString)
        Finally
            conn.Close()
        End Try
    End Sub
 
    Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
        End
    End Sub
End Class
