vba - Excel VBA取消输入框不返回false/退出子

Question

我的 Excel 工作表上有一个命令按钮，用于打开一个预加载当前选定范围的 application.inputbox，并将该范围内的单元格内容附加到这些单元格的注释中。

我正在使用 if/else 语句来检查取消按钮是否被单击，但它没有退出子程序；无论我单击“确定”还是“取消”，代码都会运行。我认为要么取消按钮没有返回“false”，要么我的 if 语句被破坏。

这是代码:

Private Sub CommentLogButton_Click()
'This Sub Appends Cell Contents to Cell Comment
Dim rng As Range
Dim WorkRng As Range
On Error Resume Next
xTitleId = "Range to Log"
Set WorkRng = Application.Selection
Set WorkRng = Application.InputBox("Range", xTitleId, WorkRng.Address, Type:=8)
If WorkRng = False Then
    Exit Sub
Else
    For Each rng In WorkRng
        rng.NoteText Text:=rng.NoteText & rng.Value & ", "
        rng.Value = ""
    Next
End If
End Sub

Answer 1

WorkRng 已声明为范围。

改变

If WorkRng = False Then

至

If WorkRng is nothing Then

将代码更改为

Private Sub CommentLogButton_Click()
    'This Sub Appends Cell Contents to Cell Comment
    Dim rng As Range, WorkRng As Range
    Dim rngAddress As String

    xTitleId = "Range to Log"

    '~~> Check if what the user selected is a valid range
    If TypeName(Selection) <> "Range" Then
        MsgBox "Select a range first."
        Exit Sub
    End If

    rngAddress = Application.Selection.Address

    On Error Resume Next
    Set WorkRng = Application.InputBox("Range", xTitleId, rngAddress, Type:=8)
    On Error GoTo 0

    If WorkRng Is Nothing Then
        Exit Sub
    Else
        For Each rng In WorkRng
            rng.NoteText Text:=rng.NoteText & rng.Value & ", "
            rng.Value = ""
        Next
    End If
End Sub
