How to build an ActiveX DLL in Delphi?

I know this is a weird question :rolleyes:
Does anyone have Delphi? I don't, so I can't check.
How do you build an ActiveX DLL in Delphi?
I'd like an example of a simple DLL with one class that contains one method, one property and one event, like the following but in Delphi, and also, all the steps required (how to create the project, etc.)

VB Code:

Option Explicit
 
Event MyEvent(ByVal TheX As Long)
 
Dim m_X As Long
 
Public Property Get X() As Long
    X = m_X
End Property
 
Public Property Let X(ByVal NewX As Long)
    m_X = NewX
End Property
 
Public Sub DoSomething()
    RaiseEvent MyEvent(m_X)
End Sub

Thanks in advance :rolleyes:
