[英]Automatically update a cell in Excel with the current date anytime any cell in a column is updated or changed
[英]Automatically enter date & time as cell is updated/changed
如果“感興趣的細胞”通過公式改變值,我希望宏在右側的空單元格上自動記錄時間和日期 。
例如,IF單元(“k3”)改變值,然后在單元格上改變時注冊DATE&TIME(“L3”); IF單元(“L3”)不為空,然后在單元(“M3”)中注冊TIME和DATE,依此類推,直到找到空單元。
到目前為止,每當“感興趣的細胞”改變值時,我都無法提示宏。 PS:后者是IF公式 ,輸出2個可能的字符串:“OK”和“ISSUE RISK WARNING”
Private sub Register_timestamp(ByVal Target As Range)
'This sub registers the date and hour at which the cells in column K:K changed values.
Dim WorkRng As Range
Dim Rng As Range
Dim xOffsetColumn As Integer
Set WorkRng = Intersect(Application.ActiveSheet.Range("K:K"))
xOffsetColumn = 1
If WorkRng Is Nothing Then
Application.EnableEvents = False
For Each Rng In WorkRng
If Not VBA.IsEmpty(Rng.Value) Then
Rng.Offset(0, xOffsetColumn).Value = Now
Rng.Offset(0, xOffsetColumn).NumberFormat = "dd-mm-yyyy, hh:mm:ss"
Else
xOffsetColumn = xOffsetColumn + 1
End If
Next
Application.EnableEvents = True
End If
End sub
如果我要手動更改受“感興趣的細胞”的IF功能影響的細胞 - 並觸發它 - ,“感興趣的細胞”發生變化的日期和時間,例如: 14/05/2019 21 :44:21
以下是您實施我的建議的方式。 確保此代碼位於正確的工作表代碼模塊上。
Private Sub Worksheet_Calculate()
Dim rMonitored As Range
Dim MonitoredCell As Range
Dim vSelected As Variant
Dim aNewValues As Variant
Dim ixFormulaCell As Long
On Error Resume Next
Set rMonitored = Me.Columns("K").SpecialCells(xlCellTypeFormulas)
On Error GoTo 0
If rMonitored Is Nothing Then Exit Sub 'No formula cells in column K
Application.EnableEvents = False 'Disable events to prevent infinite calc loop
Set vSelected = Selection 'Remember current selection (it may not be a range)
'Prepare the array that will store the new values, the cells those values are in, and whether or not there was a change
ReDim aNewValues(1 To rMonitored.Cells.Count, 1 To 3)
'Column1 = new value
'Column2 = cell address
'Column3 = did value change?
'Get the new value for each formula in column K
ixFormulaCell = 0
For Each MonitoredCell In rMonitored.Cells 'The formula cells may not be in a contiguous range
ixFormulaCell = ixFormulaCell + 1
aNewValues(ixFormulaCell, 1) = MonitoredCell.Value 'Store the new value
Set aNewValues(ixFormulaCell, 2) = MonitoredCell 'Store the cell address
Next MonitoredCell
Application.Undo 'This will undo the most recent change, which allows us to compare the new vs old to check for formula updates
ixFormulaCell = 0
For Each MonitoredCell In rMonitored.Cells
ixFormulaCell = ixFormulaCell + 1
'Check if the formula result is different
If MonitoredCell.Value <> aNewValues(ixFormulaCell, 1) Then
'Formula result found to be different, record that
'We can't put the timestamp in now because we still have to redo the most recent change
aNewValues(ixFormulaCell, 3) = True
End If
Next MonitoredCell
Application.Undo 'Redo the most recent change to put worksheet back in the new state
'Now that we've completed our comparison and have re-done the most recent change, check what did change and put in a timestamp in the next empty cell in same row
For ixFormulaCell = LBound(aNewValues, 1) To UBound(aNewValues, 1)
'Check for formula result change
If aNewValues(ixFormulaCell, 3) Then
'Formula result change found, get next empty cell in same row
With Me.Cells(aNewValues(ixFormulaCell, 2).Row, Me.Columns.Count).End(xlToLeft).Offset(, 1)
'Next empty cell found, put in the current datetime stamp and format it
.Value = Now
.NumberFormat = "dd-mm-yyyy, hh:mm:ss"
End With
End If
Next ixFormulaCell
vSelected.Select 'Re-select the remembered selection so that this operation is invisible to users
Application.EnableEvents = True 'Re-enable events so that the next calculation can be monitored for formula changes in cells of interest
End Sub
