遍历公式Excel VBA [英] Loop through formula Excel VBA

问题描述

如果没有负号，我需要遍历现有公式并删除整行.是否可以通过char逐个遍历char公式，或者有另一种方法可以识别公式中是否存在-"?

I need to go through the existing formula and delete entire row if there is no minus sign in it. Is there a way to go through the formula char by char or there is another way to identify if there is a "-" in the formula?

Sub clearvalidation()
Dim ws As Worksheet

For Each ws In ActiveWorkbook.Sheets
    Set vali = ws.Cells.Find("Validation", LookIn:=xlValues, LookAt:=xlPart)
    If Not vali Is Nothing Then
        fr = vali.Row + 2
        lr = ws.Cells(fr + 1, 6).End(xlDown).Row
        For exclrow = fr To lr
            For Each char In ws.Cells(exclrow, 7)
                If char = "-" Then
                    check = "ok"
                    Exit For
                End If
            Next char
            If check <> ok Then check = "delete"
            Select Case check
                Case Is = "ok"
                    Stop
                Case Is = "delete"
                    Stop
            End Select
        Next exclrow
    End If
    vali = Empty
Next ws

End Sub

推荐答案

如果未找到要查找的子字符串或该字符串的 index ，则应使用Instr，它将返回0子字符串(如果找到).

You should use Instr that will return 0 if the substring your are looking for isn't found or the index of that substring if it is found.

在循环删除行时，应使用Step -1从下往上进行操作，以免丢失某些行(如果删除了第i行，则第i + 1行将成为新的第i行，而您下次会错过的.)

And when you loop on rows to delete, you should go from bottom to top using Step -1 to avoid missing some rows (if the row i is deleted, the row i+1 will become the new row i and you'll miss it after the next).

Sub clearvalidation()
Dim ws As Worksheet, _
    FirstAddress As String, _
    cF As Range


For Each ws In ActiveWorkbook.Sheets
    ws.Range("A1").Activate
    With ws.Cells
        Set vali = .Find("Validation", LookIn:=xlValues, LookAt:=xlPart)
        If Not vali Is Nothing Then
            FirstAddress = vali.Address
            'If there is a result, keep looking with FindNext method
            Do
                fr = vali.Row + 2
                lr = ws.Cells(fr + 1, 6).End(xlDown).Row
                For exclrow = lr To fr Step -1
                    If InStr(1, ws.Cells(exclrow, 7).Formula, "-") Then
                        ws.Cells(exclrow, 7).EntireRow.Delete shift:=xlUp
                    Else
                    End If
                Next exclrow
                Set vali = .FindNext(vali)
            'Look until you find again the first result
            Loop While Not vali Is Nothing And vali.Address <> FirstAddress
        End If
        vali = Empty
    End With
Next ws


End Sub
