VBA如何使msgbox对某些值仅重复一次

Question

在迭代所有单元格后，我试图只打印 msgbox 的一部分。所以我只需要一次重复——所有找到的单元格只需要一次。这是整个消息框：

我只想打印消息框的这一部分：

这是代码：

Sub checkcolumns()

Dim rngCheck As Range
Dim cell As Range, j As String, mess As String
Dim TextBlockCanBeDefined, noTextBlockCanBeDefined As String

   Set rngCheck = Range("B3:B6")

For Each cell In rngCheck
If IsEmpty(cell) Then

    j = j & cell.Address(0, 0) & vbNewLine
    If cell.Offset(, 1).Value = "L" Then
        TextBlockCanBeDefined = TextBlockCanBeDefined & j & vbNewLine

    ElseIf cell.Offset(, 1).Value = "T" Then
        noTextBlockCanBeDefined = noTextBlockCanBeDefined & j & vbNewLine

    End If

End If
Next cell


mess = vbCrLf & "For the line paragraph in row:" & vbNewLine &   TextBlockCanBeDefined & "no “Text Block Row” can be defined"
mess = mess & vbCrLf & "For the table paragraph in row:" & vbNewLine & noTextBlockCanBeDefined & "is no “Text Block Row” defined"
 If mess <> "" Then MsgBox mess


End Sub

尝试以下方法：

For Each cell In rngcheck
    If IsEmpty(cell) Then
        ***j = cell.Address(0, 0) & vbNewLine***
        If cell.Offset(, 1).Value = "L" Then
            TextBlockCanBeDefined = TextBlockCanBeDefined & j & vbNewLine
            'For the table paragraph in row 7 is no “Text Block Row” defined
            'rngcheck.ClearContents
        ElseIf cell.Offset(, 1).Value = "T" Then
            noTextBlockCanBeDefined = noTextBlockCanBeDefined & j & vbNewLine
            'cell.Clear
        End If
        'mess = mess & vbCrLf & j & "is ok"
    End If
Next cell

mess = vbCrLf & "For the line paragraph in row:" & vbNewLine & TextBlockCanBeDefined & "no “Text Block Row” can be defined"
mess = mess & vbCrLf & "For the table paragraph in row:" & vbNewLine & noTextBlockCanBeDefined & "is no “Text Block Row” defined"
