Excel VBA for循环体积计算
我正在创build一个程序，可以让农业生产者轻松地计算一个jar的体积。 我特别希望他们能够为他们的坦克input多个维度并分别计算每个坦克的体积。 尺寸将用逗号分隔，我希望将它们拆分并放入自己的列中。 然后，我希望Excel取每列数据并应用体积公式来获得圆柱体积。 我不知道该怎么做，而且我觉得需要循环遍历每一列，例如第1列，第2列，等等。下面是代码。
'Seperates values that are seperated by a comma and then puts them in their own column Public Sub CommaSep() Selection.TextToColumns _ Destination:=Columns(3), _ DataType:=xlDelimited, _ TextQualifier:=xlDoubleQuote, _ ConsecutiveDelimiter:=False, _ Tab:=True, _ Semicolon:=False, _ Comma:=False, _ Space:=False, _ Other:=True, _ OtherChar:="," End Sub 坦克尺寸的代码是
Public Sub NoInput() Sheets.Add.Name = "Hidden Information" Worksheets(2).Activate Dim tankCount As Integer tankCount = Application.InputBox("Enter the Number of Tanks that will be in the Secondary Containment", "Known Tank Quantity", 1) If tankCount = False Then Call DeleteSheets Exit Sub Else tankTotal = tankCount End If Dim knownVol As Variant knownVol = Application.InputBox("Enter the Known Volume of the Tank in Gallons. If volume is not known then enter 0", "Known Tank Volume", 0) If knownVol = "" Then Call DeleteSheets Exit Sub ElseIf knownVol > 0 Then Application.Worksheets(1).Range("A6").Value = "Known Tank Volume" Application.Worksheets(1).Range("B6").Value = knownVol ' Application.Worksheets(2).Range("A6").Value = "Known Tank Volume" ' Application.Worksheets(2).Range("B6").Value = knownVol ' Call SPCCSizedSecondary ' Exit Sub Else End If Dim diameter As Variant diameter = Application.InputBox("Enter the Diameter of the Tanks in feet seperated by commas", "Diameter", 1) If diameter = False Then Call DeleteSheets Exit Sub Else Application.Worksheets(1).Range("A4").Value = "Diameter" Application.Worksheets(1).Range("B4").Value = diameter End If Dim length As Variant length = Application.InputBox("Enter the Length of the Tanks in feet seperated by commas", "Length", 1) If length = False Then Call DeleteSheets Exit Sub Else Application.Worksheets(1).Range("A5").Value = "Length" Application.Worksheets(1).Range("B5").Value = length End If 'Dim knownVol As Variant 'knownVol = Application.InputBox("Enter the Known Volume(s) of the Tank in Gallons seperated by commas. If volume is not known then enter 0", "Known Tank Volume", 0) 'If knownVol = False Then ' Call DeleteSheets ' Exit Sub 'Else ' Application.Worksheets(1).Range("A6").Value = "Known Tank Volume" ' Application.Worksheets(1).Range("B6").Value = knownVol 'End If Columns(1).AutoFit Columns(2).AutoFit 'Call DeleteSheets End Sub
鉴于你对你所要做的描述，我build立了一个模拟（希望）提供一些指导。 我绝不是一个专家，所以我相信有更好的方法来做到这一点， 此外，这里基本没有validation，所以要谨慎。
尺寸将以逗号分隔，我希望将它们拆分并放入自己的列中。
如果你接受以逗号分隔的input，我说接受input并把它分成一个数组。 我假设长度/直径将需要精度，所以我用这两个函数来转换一个逗号分隔的stringinput到一个双数组
Function csv_to_string_array(strCSV as String) As String() csv_to_string_array = Split("," & strCSV, ",") 'don't know why, but needs a leading comma otherwise it skips the first input End Function Function str_to_double_array(strArray() as String) As Double() Dim tempDblArray() As Double ReDim tempDblArray(UBound(strArray)) Dim i As Integer For i = 1 To UBound(strArray) tempDblArray(i) = CDbl(strArray(i)) Next i str_to_double_array = tempDblArray() End Function
然后我用它们来填充我的双数组（使用InputBox的input）
dblDiameter() = str_to_double_array(csv_to_string_array(strInputDiameter))
然后，我希望Excel取每列数据并应用体积公式来获得圆柱体积。
我也为此做了一个function，因为它似乎是有道理的。 如果你愿意，可以自由地使pi更准确。
Function calc_cylinder_volume(dblDiameter as Double, dblLength as Double) As Double calc_cylinder_volume = (Application.WorksheetFunction.Pi() * ((dblDiameter ^ 2) / 4) * dblLength) End Function
有了这些，我build立了一个NoInput类似于你的接受input并NoInput和体积计算。 它不会做任何过于激进的事情，只是从A1开始，为每个直径和长度input下降一行，然后计算每个音量。
这是整个事情在一起。 您可以将所有代码复制到一个模块中，然后运行NoInput()来启动它。
Option Explicit Sub NoInput() Dim strInputDiameter As String strInputDiameter = Application.InputBox("Tank Diameter") 'get diameter inputs Dim strInputLength As String strInputLength = Application.InputBox("Tank Length") 'get length inputs 'convert comma separated inputs to arrays of Doubles Dim dblDiameter() As Double dblDiameter() = str_to_double_array(csv_to_string_array(strInputDiameter)) Dim dblLength() As Double dblLength() = str_to_double_array(csv_to_string_array(strInputLength)) Dim rngCurrCell As Range Set rngCurrCell = ActiveSheet.Range("A1") 'set number of containers to whichever input had the least values Dim intContainerCount As Integer intContainerCount = WorksheetFunction.Min(UBound(dblDiameter), UBound(dblLength)) 'calculate volume for each container, output to sheet Dim i As Integer For i = 1 To intContainerCount rngCurrCell.Value = "Diameter " & i rngCurrCell.Offset(0, 1).Value = dblDiameter(i) rngCurrCell.Offset(1, 0).Value = "Length " & i rngCurrCell.Offset(1, 1).Value = dblLength(i) rngCurrCell.Offset(2, 0).Value = "Volume " & i rngCurrCell.Offset(2, 1).Value = calc_cylinder_volume(dblDiameter(i), dblLength(i)) Set rngCurrCell = rngCurrCell.Offset(0, 3) Next i End Sub Function csv_to_string_array(strCSV As String) As String() csv_to_string_array = Split("," & strCSV, ",") 'don't know why, but needs a leading comma otherwise it skips the first input End Function Function str_to_double_array(strArray() As String) As Double() Dim tempDblArray() As Double ReDim tempDblArray(UBound(strArray)) Dim i As Integer For i = 1 To UBound(strArray) tempDblArray(i) = CDbl(strArray(i)) Next i str_to_double_array = tempDblArray() End Function Function calc_cylinder_volume(dblDiameter As Double, dblLength As Double) As Double calc_cylinder_volume = (Application.WorksheetFunction.Pi() * ((dblDiameter ^ 2) / 4) * dblLength) End Function
