使用宏在excel文件的所有表格中搜索字符串

2018-06-13 07:38:37

我写了一个宏，它将在excel文件的所有表格中搜索一个字符串。该宏将激活第一个工作表以及包含搜索字符串的工作表中的单元格。如果没有找到，它会显示一条消息。这个宏运行良好。我想扩展这个功能来覆盖包含这个字符串而不是第一个的所有表单。所以我修改了宏，但没有按预期工作。我已经给出了下面的代码，并在它显示错误的地方发表了评论。

Dim sheetCount As Integer
Dim datatoFind

Sub Button1_Click()

Find_Data

End Sub

Private Sub Find_Data()
    Dim counter As Integer
    Dim currentSheet As Integer
    Dim notFound As Boolean
    Dim yesNo As String

    notFound = True

    On Error Resume Next
    currentSheet = ActiveSheet.Index
    datatoFind = InputBox("Please enter the value to search for")
    If datatoFind = "" Then Exit Sub
    sheetCount = ActiveWorkbook.Sheets.Count
    If IsError(CDbl(datatoFind)) = False Then datatoFind = CDbl(datatoFind)
    For counter = 1 To sheetCount
        Sheets(counter).Activate

        Cells.Find(What:=datatoFind, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
        :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
        False, SearchFormat:=False).Activate

        If InStr(1, ActiveCell.Value, datatoFind) Then
            If HasMoreValues(counter + 1) Then 'Not completing the method and directly entering
                yesNo = MsgBox("Do you want to continue search?", vbYesNo)
                If yesNo = vbNo Then
                    notFound = False
                    Exit For
                End If
            End If
            Sheets(counter).Activate
        End If
    Next counter
    If notFound Then
        MsgBox ("Value not found")
        Sheets(currentSheet).Activate
    End If
End Sub

Private Function HasMoreValues(ByVal sheetCounter As Integer) As Boolean
    HasMoreValues = False
    Dim str As String

    For counter = sheetCounter To sheetCount
        Sheets(counter).Activate

        str = Cells.Find(What:=datatoFind, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
        :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
        False, SearchFormat:=False).Value 'Not going further than this i.e. following code is not executed

        If InStr(1, str, datatoFind) Then
            HasMoreValues = True
            Exit For
        End If
    Next counter
End Function

我能够解决我的问题，并发布了可能需要它的代码

问候，

问题是Cells.Find返回一个范围。当你在你的函数HasMoreValues使用它时，你可以像这样使用它：

Cells.Find(...).Value

但是返回的范围不会正确地转换为.value。您可以使用.text而不是.value来解决此问题，如下所示：

Cells.Find(...).text

或完全：

str = Cells.Find(What:=datatoFind, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
  :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
  False, SearchFormat:=False).text

为了完全正确，您应该将find的结果set为Range变量，然后通过该变量进行访问，以防Find搜索返回任何内容。然而根据文档Cells.Find总是返回一个单元格的范围，所以你可能没问题。
