[英]Loop through formula Excel VBA
I need to go through the existing formula and delete entire row if there is no minus sign in it. 如果没有减号,我需要遍历现有公式并删除整行。 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?
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“-”?
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
To rapidly work through each worksheet and delete rows that do not contain a hyphen in column G, the AutoFilter Method will likely work best. 若要快速浏览每个工作表并删除G列中不包含连字符的行,“自动筛选方法”可能会最好地工作。
Sub Macro1()
Dim w As Long
For w = 1 To Worksheets.Count
With Worksheets(w)
If .AutoFilterMode Then .AutoFilter = False
With .Cells(1, 1).CurrentRegion
.AutoFilter Field:=7, Criteria1:="<>*-*"
With .Resize(.Rows.Count - 1, .Columns.Count).Offset(1, 0)
If Application.Subtotal(103, .Cells) Then
.Cells.EntireRow.Delete
End If
End With
End With
End With
Next w
End Sub
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. 您应该使用
Instr
,如果找不到要查找的子字符串,则返回0;如果找到该子字符串的索引 ,则返回0。
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). 并且,当您循环删除行时,应使用
Step -1
从下至上进行操作,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,而您会错过它下一个)。
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
