各位先進,
我使用 vb.net code 開發的 interface 相關 (dll) code, 欲轉成 C++ (dll), 請問該如何處理? vb.net code 如下。

'
Public Interface IInterface01
Sub Check(ByVal sTime As String)
End Interface

'

Public Class UserINFOs
'
Private Class TheUSER
Public USERRef As IInterface01 = Nothing
Public CheckInTIME As String
End Class

Private m_UserList As List(Of TheUSER) = New List(Of TheUSER)()

Public Sub CheckIn(ByRef xUser As Object)
    ' xUser 可以是一個 class object 或是 Form object

    Dim AUser As TheUSER = New TheUSER()

    AUser.USERRef = xUser
    AUser.CheckInTIME = Now.ToString("yyyy/MM/dd HH:mm:ss")
    AUser.USERRef.Check(AUser.CheckInTIME)
End Sub

End Class

Public Class TestClass
Implements IInterface01

Public Sub Check(sTime As String) Implements IInterface01.Check
    MsgBox(sTime)
End Sub

End Class

01.  "Interface IInterface01" 和 "Class TheUSER" 和 "Class UserINFOs" 欲轉換成 C++ 的 dll
02.  "Class TestClass" 仍用 vb.net, code 不變更。

Thanks !!
