在Excel VBA中实例化另一个类中的对象

Question

我正在使用Excel VBA在那里我有很多的数据集的一个项目,每一个填充了一系列的"病人",这有很多的参数(如治疗,预后等).为了解决这个问题,我打算创建一个名为"患者"的类,其中包含治疗和结果等属性.然后创建一个名为"dataset"的类,其公共属性为"patient".我已经创建了类,我可以实例化一个数据集对象.但是,如何在数据集对象中实例化患者对象,或理想情况下是一组患者对象？

数据集类模块:

Private pNumber As Integer
Public Patient As Patient

Public Property Get Number() As Integer
    Number = pNumber
End Property
Public Property Let Number(p As Integer)
    pNumber = p
End Property

患者类模块:

Private pID As Integer
Private pTreatment As Boolean
Private pResponse As Single

Public Property Get ID() As Integer
    ID = pID
End Property
Public Property Let ID(p As Integer)
    pID = p
End Property

Public Property Get Treatment() As Boolean
    Treatment = pTreatment
End Property
Public Property Let Treatment(p As Boolean)
    pTreatment = p
End Property

Public Property Get Response() As Single
    Response = pResponse
End Property
Public Property Let Response(p As Single)
    pResponse = p
End Property

主要模块

Sub main()

Dim data1 As Dataset
Set data1 = New Dataset

'code to instantiate array of patient within data1 here

End Sub

数据集将被更好地指定为这样的。

我会按照它的预期名称来称呼这个类，所以Patients：

private colPatients as new collection

public function add(aPatient as patient)
  colPatients.add aPatient, aPatient.Id
end function

public property get count() as long
  count = colPatients.count
end property 

public property get items() as collection
  set items = colPatients
end property 

public property get item(vItem as variant) as patient
  set item = colPatients(vItem)
end property 

public sub remove(vItem as variant)
  colPatients.remove vItem
end sub 

所以要使用：

dim patientCollection as patients
Sub main()

Set patientCollection = New patients

'code to instantiate array of patient within data1 here
IDs = Array(1,2,3)
treats = array("x","y","z")

dim x as integer
dim p as patient
for x = lbound(IDs) to Ubound(IDs)
   set p= new patient
   p.id = IDs(x)
   p.treatment = treats(x)
   patientCollection.add p
   set p = nothing
next x


End Sub
