Password Generator class

Hi this is just a small class I made for one of my projects to generate a random password from letters,numbers and special chars easy to add to your project. Hope you find it usfull

Create a new project add a class call it cPwsGen.vb
Add the code below to the class.

vbnet Code:

Imports System.Text
 
Public Class cPwsGen
    'Private variables.
    Private pLen As Integer = 0
    Private pPasswordType As TGenPass
 
    'Private password sources
    Private Const Alpha As String = "abcdefghijklmnopqrstuvwxyz"
    Private Const Digits = "0123456789"
    Private Const Hexdecimal = "abcdef"
    Private Const SpecialChars = "!@#$%^&*()<>=/\+-*"
 
    Public Enum TGenPass
        Alpha = 0
        AlphaDigit = 1
        Digits = 2
        Hexdecimal = 3
        SpecialChar = 4
        SpecialAlpha = 5
        SpecialDigit = 6
    End Enum
 
    Private Function GetPassword(ByVal Length As Integer, Optional ByVal GenType As TGenPass = TGenPass.Alpha) As String
        Dim x As Integer
        Dim r As Integer
        Dim CharStream As String
        Dim sb As StringBuilder
 
        sb = New StringBuilder
        CharStream = vbNullString
 
        'Password types
        Select Case GenType
            Case TGenPass.Alpha
                CharStream = Alpha
            Case TGenPass.Digits
                CharStream = Digits
            Case TGenPass.Hexdecimal
                CharStream = Hexdecimal & Digits
            Case TGenPass.AlphaDigit
                CharStream = Digits & Alpha
            Case TGenPass.SpecialChar
                CharStream = SpecialChars
            Case TGenPass.SpecialAlpha
                CharStream = Alpha & SpecialChars
            Case TGenPass.SpecialDigit
                CharStream = Digits & SpecialChars
        End Select
 
        For x = 1 To Length
            'Ini Random numbers
            Call Randomize()
            'Get random number
            r = Int(Rnd() * Len(CharStream) + 1)
            'Build generated password.
            Call sb.Append(Mid$(CharStream, r, 1))
        Next x
 
        GetPassword = sb.ToString
    End Function
 
    Public Property PasswordType As TGenPass
        Get
            'Return password type.
            PasswordType = pPasswordType
        End Get
        Set(ByVal value As TGenPass)
            'Set password type.
            pPasswordType = value
        End Set
    End Property
 
    Public Property PasswordLength As Integer
        Get
            'Return password length.
            PasswordLength = pLen
        End Get
        Set(ByVal value As Integer)
            'Set password length.
            pLen = value
        End Set
    End Property
 
    Public ReadOnly Property Password As String
        Get
            'Return generated password.
            Password = GetPassword(PasswordLength, PasswordType)
        End Get
    End Property
End Class

For the example add this to a command button.

vbnet Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim GenPws As New cPwsGen
        'Set password generator props
        GenPws.PasswordLength = 8
        GenPws.PasswordType = cPwsGen.TGenPass.AlphaDigit
        'Example
        Call MsgBox(GenPws.Password, vbInformation Or vbOKOnly, "Your Passsword")
    End Sub

Your code is stuck in VB6! Here's a translation to VB.NET:

Code:

---

Imports System.Text

Public Class cPwsGen
    'Private variables.
    Private pLen As Integer = 0
    Private pPasswordType As TGenPass

    'Private password sources
    Private Const Alpha As String = "abcdefghijklmnopqrstuvwxyz"
    Private Const Digits As String = "0123456789"
    Private Const Hexdecimal As String = "abcdef"
    Private Const SpecialChars As String = "!@#$&#37;^&*()<>=/\+-*"

    Public Enum TGenPass
        Alpha
        AlphaDigit
        Digits
        Hexdecimal
        SpecialChar
        SpecialAlpha
        SpecialDigit
    End Enum

    Private Function GetPassword(ByVal Length As Integer, Optional ByVal GenType As TGenPass = TGenPass.Alpha) As String
        Dim r As New Random()
        Dim sb As New StringBuilder()
        Dim CharStream As String

        'Password types
        Select Case GenType
            Case TGenPass.Alpha
                CharStream = Alpha
            Case TGenPass.Digits
                CharStream = Digits
            Case TGenPass.Hexdecimal
                CharStream = Hexdecimal & Digits
            Case TGenPass.AlphaDigit
                CharStream = Digits & Alpha
            Case TGenPass.SpecialChar
                CharStream = SpecialChars
            Case TGenPass.SpecialAlpha
                CharStream = Alpha & SpecialChars
            Case TGenPass.SpecialDigit
                CharStream = Digits & SpecialChars
            Case Else
                Throw New ArgumentException("Invalid generation type!")
        End Select

        For x As Integer = 1 To Length
            'Add a random character to the password:
            sb.Append(CharStream(r.Next(0, CharStream.Length)))
        Next

        Return sb.ToString()
    End Function

    Public Property PasswordType As TGenPass
        Get
            'Return password type.
            Return pPasswordType
        End Get
        Set(ByVal value As TGenPass)
            'Set password type.
            pPasswordType = value
        End Set
    End Property

    Public Property PasswordLength As Integer
        Get
            'Return password length.
            Return pLen
        End Get
        Set(ByVal value As Integer)
            'Set password length.
            pLen = value
        End Set
    End Property

    Public ReadOnly Property Password As String
        Get
            'Return generated password.
            Return GetPassword(PasswordLength, PasswordType)
        End Get
    End Property
End Class

Thanks for the convert I am still new at VB.NET So any fixes help thanks.
