How can I create .dll files in .net and use it in my asp.net program

I ve got a class file named MyClass with several generic functions in it

I wanted to convert this MyClass into a .dll file

How can I use this .dll file so that I can call/reuse my functions into my programs. :( :(

 

Thank u

copy the dll to your bin directory and add a reference to it in your project...

Hi,

You can create Class Liabrary type project in Visula Studio. Add you code and compile. Your DLL is ready :)

Just add the reference of the dll in you asp.net project. And don't forget to add Import/Using directive at the top of Aspx page.

Public Class InputBox
   Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

   Public Sub New()
       MyBase.New()

       'This call is required by the Windows Form Designer.
       InitializeComponent()

       'Add any initialization after the InitializeComponent() call

   End Sub

   Public Sub New(ByVal Title As String, ByVal Message As String)
       MyBase.New()

       'This call is required by the Windows Form Designer.
       InitializeComponent()

       'Add any initialization after the InitializeComponent() call
       Me.Text = Title
       Me.lblMessage.Text = Message
   End Sub


   'Form overrides dispose to clean up the component list.
   Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
       If disposing Then
           If Not (components Is Nothing) Then
               components.Dispose()
           End If
       End If
       MyBase.Dispose(disposing)

ok, I got the answer, I need to add references of System.Windows.Forms for inherit the method in the class.
