[英]Need to delete the previous row in a Excel sheet based on a cell value in a current cell in Excel VBA
I'm writing my first macro for this project that has the following data exports from a motion sensor. 我正在为这个项目编写我的第一个宏,它从运动传感器输出以下数据。 It has a 'No Motion' after every 'Motion Detected' row.
每次“检测到运动”行后都会显示“无运动”。 This 'No Motion' is a glitch within that sensor's firmware that I cannot edit.
这个'No Motion'是我无法编辑的传感器固件中的一个小故障。 So it looks like this:
所以它看起来像这样:

I need to remove the 'No Motion that shows up immediately after the 'Motion Detected' rows. 我需要删除“运动检测到”行后立即显示的“无运动”。
With the help of a code online I edited, I got this: 在我编辑的在线代码的帮助下,我得到了这个:
Sub Macro_Delete_rows()
Dim Firstrow As Long
Dim Lastrow As Long
Dim Lrow As Long
Dim CalcMode As Long
Dim ViewMode As Long
With Application
CalcMode = .Calculation
.Calculation = xlCalculationManual
.ScreenUpdating = False
End With
With ActiveSheet
.Select
ViewMode = ActiveWindow.View
ActiveWindow.View = xlNormalView
.DisplayPageBreaks = False
'Set the first and last row to loop through
Firstrow = .UsedRange.Cells(1).Row
Lastrow = .UsedRange.Rows(.UsedRange.Rows.Count).Row
For Lrow = Lastrow To Firstrow Step -1
With .Cells(Lrow, "F")
If Not IsError(.Value) Then
If .Value = "Motion Detected" Then .Rows(Lrow - 1).EntireRow.Delete
'Here I try to delete previous row to this row
End If
End With
Next Lrow
End With
ActiveWindow.View = ViewMode
With Application
.ScreenUpdating = True
.Calculation = CalcMode
End With
End Sub
This doesn't really work and mostly I end up deleting the wrong rows. 这实际上并不起作用,而且我最终会删除错误的行。 Where am I going wrong?
我哪里错了?
Thank you for the help! 感谢您的帮助!
Try this as your For
loop: 试试这个
For
循环:
For Lrow = Lastrow To Firstrow Step -1
With .Cells(Lrow, "F")
If Not IsError(.Value) Then
If .Value = "No Motion" And .Offset(-1, 0) = "Motion Detected" Then
.EntireRow.Select
.EntireRow.Delete
End If
End If
End With
Next Lrow
The idea is that it looks to see if the current row is "No Motion" and the previous row is "Motion Detected". 其想法是查看当前行是否为“无运动” ,前一行是否为“运动检测”。 If so, delete that "No Motion" row.
如果是,请删除“无运动”行。
Your original code was on the right track, but notice it wouldn't delete that last "No Motion" line, since there's no "Motion Detected" row after it. 您的原始代码在正确的轨道上,但请注意它不会删除最后一个“无运动”行,因为它之后没有“运动检测”行。
This will solve your problem. 这将解决您的问题。
Sub Macro_Delete_rows()
Dim TotalRows As Long
TotalRows = Application.WorksheetFunction.CountA(Sheets("yourSheetName").Range("A:A"))
For i = 2 To TotalRows
'You can delete the data by 0 before No Moton Cell
'if G colomn has No Motion
Range("G" & i).Select
If ActiveCell.Value = "No Motion" Then
ActiveCell.EntireRow.Delete
i = 1 - 1
End If
' 'If F column has 0
' Range("F" & i).Select
' If ActiveCell.Value = 0 Then
' ActiveCell.EntireRow.Delete
' i = 1 - 1
' End If
Next i
End Sub
