如果未找到搜索项则显示消息框

搜索完成后，会弹出一个窗口：弹出窗口完成

当我单击“完成”时，它会打开一个包含结果的新工作表：

结果表

我希望，当未找到任何内容时，弹出窗口会显示以下文字“未找到任何内容”。

请你帮助我好吗？

以下是完整代码：

Sub SearchFolders()
    Dim fso As Object
    Dim fld As Object
    Dim strSearch As String
    Dim strPath As String
    Dim strFile As String
    Dim wOut As Worksheet
    Dim wbk As Workbook

    Dim rFound As Range
    Dim strFirstAddress As String

    On Error GoTo ErrHandler
    Application.ScreenUpdating = False

    'Change as desired
    strPath = "c:\MyFolder"
    strSearch = "Specific text"

    Set wOut = Worksheets.Add
    lRow = 1
    With wOut
        .Cells(lRow, 1) = "Workbook"
        .Cells(lRow, 2) = "Worksheet"
        .Cells(lRow, 3) = "Cell"
        .Cells(lRow, 4) = "Text in Cell"
        Set fso = CreateObject("Scripting.FileSystemObject")
        Set fld = fso.GetFolder(strPath)

        strFile = Dir(strPath & "\*.xls*")
        Do While strFile <> ""
            Set wbk = Workbooks.Open _

              UpdateLinks:=0, _

            For Each wks In wbk.Worksheets
                Set rFound = wks.UsedRange.Find(strSearch)
                If Not rFound Is Nothing Then
                    strFirstAddress = rFound.Address
                End If
                Do
                    If rFound Is Nothing Then
                        Exit Do
                    Else
                        lRow = lRow + 1

                        .Cells(lRow, 2) = wks.Name
                        .Cells(lRow, 3) = rFound.Address
                        .Cells(lRow, 4) = rFound.Value
                    End If
                    Set rFound = wks.Cells.FindNext(After:=rFound)
                Loop While strFirstAddress <> rFound.Address
            Next

            wbk.Close (False)
            strFile = Dir
        Loop
        .Columns("A:D").EntireColumn.AutoFit
    End With
    MsgBox "Done"

ExitHandler:
    Set wOut = Nothing
    Set wks = Nothing
    Set wbk = Nothing
    Set fld = Nothing
    Set fso = Nothing
    Application.ScreenUpdating = True
    Exit Sub

ErrHandler:
    MsgBox Err.Description, vbExclamation
    Resume ExitHandler
End Sub

您可以测试计数器是否lrow大于 0。如果是，则表示找到了某些内容。如果不是，则表示没有找到任何内容。将代码中您写入的部分更改MsgBox "Done"为：

If lrow > 0 Then
    MsgBox "Done"
Else
    MsgBox "Nothing found"
End If
