VBA：用值初始化对象？

Question

我希望能够以初始化

CArticle具有下列性质：

Private pNumber As String 
Private pQuantity As Double 

与任一空的，预先定义的值或电流值。我怎样才能做到这一点？我沿线的思考的东西：

新的空CArticle

pNumber 
pQuantity 

新的虚拟CArticle

pNumber 
pQuantity = 99999 

新初始化CArticle(number, quantity)

pNumber = number 
pQuantity = quantity 

Answer 1

它是一个痛苦脖子，但这是做到这一点的唯一方法。

文件CArticle

Option Explicit 

Private pNumber As String 
Private pQuantity As Double 

Private Sub Class_Initialize() 
    pNumber = vbNullString 
    pQuantity = 0 
End Sub 

Public Sub InitializeWithValues(ByVal number As String, ByVal quantity As Double) 
    pNumber = number 
    pQuantity = quantity 
End Sub 

Public Sub InitializeDefaultValues() 
    pNumber = vbNullString 
    pQuantity = 99999 
End Sub 

，并调用模块中

Dim art As New CArticle  ' Initialize value to empty 
art.InitializeWithValues "Bowtie", 100  ' and assign values 

Set art = New CArticle  ' Initialize values to empty 
art.InitializeDefaultValues ' Initialize values to default
