vba - 为什么应用程序级别的 SelectionChange 事件不起作用？

Question

我创建了一个小宏来返回唯一值的数量，并在选择范围时将其显示在 Excel 的状态栏中。这在文档级别工作得很好。但是，当我尝试在应用程序级别运行 SelectionChange 事件时，该事件并未启动。以下是我所拥有的。

类模块“ExcelEventCapture”

Option Explicit

Public WithEvents ExcelApp As Application

Private Sub ExcelApp_SelectionChange(ByVal Target As Range)
    If TypeName(Target) = "Range" Then
        Application.StatusBar = "Unique Count: " & CountUnique(Target)
    End If
End Sub

Private Function CountUnique(rng As Range) As Long
        Dim dict As Dictionary
        Dim cell As Range
        Set dict = New Dictionary
        For Each cell In rng.Cells
            If cell.Value2 <> 0 Then
                If Not dict.Exists(cell.Value) Then
                    dict.Add cell.Value, 0
                End If
            End If
        Next
        CountUnique = dict.Count
End Function

本工作簿

Option Explicit

Dim myobject As New ExcelEventCapture

Sub Workbook_Open()
    Set myobject.ExcelApp = Application
End Sub

我错过了什么？谢谢

Application 中不存在

SelectionChange 事件类(class)。

您可以使用SheetSelectionChange事件，无需检查 Target 类名。

Private Sub ExcelApp_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)    
    Application.StatusBar = "Unique Count: " & CountUnique(Target)
End Sub
