Dim V as Long;

这是一条Visual Basic语言的声明语句,它用于定义一个名为V的变量,并将其类型指定为Long(长整型)。在Visual Basic中,Long类型的变量可以存储32位的整数值,其取值范围为-2,147,483,648到2,147,483,647。这条语句可以用于在程序中创建一个长整型变量V,以便在运行时存储和操作32位整数值。在实际应用中,变量名和类型可以根据需要进行修改。

使用数组的方式,优化以下代码:Sub 一键检查明细数据() On Error Resume Next Application.ScreenUpdating = False Dim ws As Worksheet Set ws = Worksheets("报表1") Dim lastRow As Long lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row Dim i As Long For i = 2 To lastRow Dim val As Double, judgeVal As String, v2 As Double, v3 As String val = CDbl(ws.Cells(i, 10).Value) judgeVal = CStr(ws.Cells(i, 11).Value) v2 = CDbl(ws.Cells(i, 12).Value) v3 = CStr(ws.Cells(i, 13).Value) If InStr(judgeVal, "-") > 0 Then Dim item() As String item = Split(judgeVal, "-") Dim firstVal As Double, secondVal As Double firstVal = CDbl(item(0)) secondVal = CDbl(item(1)) Dim item2() As String item2 = Split(v3, "-") Dim S1 As Double, S2 As Double S1 = CDbl(item2(0)) S2 = CDbl(item2(1)) If firstVal > val Or val > secondVal Then ws.Cells(i, 10).Font.Color = 255 ws.Cells(i, 9).Font.Color = 255 ws.Cells(i, 9).Value = ws.Cells(i, 10).Value Else ws.Cells(i, 10).Font.ColorIndex = xlAutomatic ws.Cells(i, 9).Font.ColorIndex = xlAutomatic ws.Cells(i, 9).Value = "" End If If S1 > v2 Or v2 > S2 Then ws.Cells(i, 12).Font.Color = 255 Else ws.Cells(i, 12).Font.ColorIndex = xlAutomatic End If If ws.Cells(i, 12).Value = ws.Cells(i, 13).Value Then ws.Cells(i, 12).Font.ColorIndex = xlAutomatic End If End If Next i ActiveWorkbook.RefreshAll Application.ScreenUpdating = True End Sub
下面是使用数组的优化代码:
Sub 一键检查明细数据()
On Error Resume Next
Application.ScreenUpdating = False
Dim ws As Worksheet
Set ws = Worksheets("报表1")
Dim lastRow As Long
lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
Dim vals() As Double, judgeVals() As String, v2s() As Double, v3s() As String
ReDim vals(2 To lastRow), judgeVals(2 To lastRow), v2s(2 To lastRow), v3s(2 To lastRow)
Dim i As Long
For i = 2 To lastRow
vals(i) = CDbl(ws.Cells(i, 10).Value)
judgeVals(i) = CStr(ws.Cells(i, 11).Value)
v2s(i) = CDbl(ws.Cells(i, 12).Value)
v3s(i) = CStr(ws.Cells(i, 13).Value)
Next i
For i = 2 To lastRow
If InStr(judgeVals(i), "-") > 0 Then
Dim item() As String
item = Split(judgeVals(i), "-")
Dim firstVal As Double, secondVal As Double
firstVal = CDbl(item(0))
secondVal = CDbl(item(1))
Dim item2() As String
item2 = Split(v3s(i), "-")
Dim S1 As Double, S2 As Double
S1 = CDbl(item2(0))
S2 = CDbl(item2(1))
If firstVal > vals(i) Or vals(i) > secondVal Then
ws.Cells(i, 10).Font.Color = 255
ws.Cells(i, 9).Font.Color = 255
ws.Cells(i, 9).Value = ws.Cells(i, 10).Value
Else
ws.Cells(i, 10).Font.ColorIndex = xlAutomatic
ws.Cells(i, 9).Font.ColorIndex = xlAutomatic
ws.Cells(i, 9).Value = ""
End If
If S1 > v2s(i) Or v2s(i) > S2 Then
ws.Cells(i, 12).Font.Color = 255
Else
ws.Cells(i, 12).Font.ColorIndex = xlAutomatic
End If
If ws.Cells(i, 12).Value = ws.Cells(i, 13).Value Then
ws.Cells(i, 12).Font.ColorIndex = xlAutomatic
End If
End If
Next i
ActiveWorkbook.RefreshAll
Application.ScreenUpdating = True
End Sub
主要改动是将每个单元格的数值和字符串值存储到数组中,然后进行操作。这样可以减少对单元格的读写操作,提高代码执行效率。
W2 寫入公式=(V2/天數)/(U2/天數),如果V和U所在列的月份如果是1.3.5.7.8.10.12月則除31,如果是2.4.6.9.11則除30,如何用VBA表達
您可以使用以下的 VBA 代码来实现根据月份计算公式的功能:
```vba
Sub CalculateW2()
Dim lastRow As Long
Dim i As Long
lastRow = Cells(Rows.Count, "V").End(xlUp).Row ' 获取 V 列的最后一行
For i = 2 To lastRow ' 从第二行开始循环,假设第一行是标题行
Dim month As Integer
Dim daysInMonth As Integer
Dim V As Double
Dim U As Double
month = Month(Cells(i, "V").Value) ' 获取月份
V = Cells(i, "V").Value ' 获取 V 列的值
U = Cells(i, "U").Value ' 获取 U 列的值
Select Case month
Case 1, 3, 5, 7, 8, 10, 12 ' 如果是 31 天的月份
daysInMonth = 31
Case 2, 4, 6, 9, 11 ' 如果是 30 天的月份
daysInMonth = 30
Case Else ' 如果是其他月份(如闰年的 2 月)
daysInMonth = 28 ' 假设每个月都是 28 天
End Select
Cells(i, "W").Value = (V / daysInMonth) / (U / daysInMonth) ' 计算并写入 W 列的值
Next i
End Sub
```
您可以将上述代码复制到 Excel 的 VBA 编辑器中(按下 `Alt + F11` 打开),然后在适当的地方调用 `CalculateW2` 过程,即可实现根据月份计算公式并将结果写入 W 列的功能。请注意,这里假设您的数据从第二行开始,且 V 列和 U 列分别为第 21 和 22 列。如果不是,请根据实际情况进行调整。
