比如TextBox控件，默认Text属性，那么类模块如何自己定义默认成员呢？

暴风雨讲的是控件，同样适用于类
类模块：
Private mText As String
Public Property Get Text() As Variant
Text = mText
End Property
Public Property Let Text(ByVal vNewValue As Variant)
mText = vNewValue
End Property
窗体：
Private Sub Command1_Click()
Dim x As New Class1
x = "123 "
Print x.Text
End Sub
