アクティブなワークシートのすべての数値を指定された小数点以下の桁数に丸める OpenOffice Calc マクロ (Basic) があります。9000 行のスプレッドシートの 100 行を処理するのに約 4 秒かかります。各行には 35 列あり、そのうち 19 列は数値です。
これをより速く実行するにはどうすればよいですか? これは私が OpenOffice 用に書いた初めてのマクロなので、私が聞いたことのない高速な方法がある可能性があります。これが私のコードです:
Dim oFunction as Object
' Round all Value cells (cells that do not contain Text or Functions) on the current sheet to as many decimal places as user requests.
Sub RoundUsedCells
Dim oSheet As Object, oUsedRange as Object, oCursor as Object, oCell As Object
Dim row, column,lastRow, lastColumn
Dim places$, placesToRound
Dim roundedValue as Double
' Ask user how many decimal places to round
places$ = InputBox ("Round to how many places (leave blank to cancel)?")
if (places$ is Nothing or places$ = "") then
' Do nothing.
else
placesToRound = CInt(places$)
' Get the currently active sheet.
oSheet = thiscomponent.getcurrentcontroller.activesheet
' Create a one cell range at the origin,
' then create a cursor that allows us to extend the range to include all the "used" cells.
' The cursor will then allow us to find out how large is that used range.
oUsedRange = oSheet.getCellRangeByPosition(0,0,0,0)
oCursor = oSheet.createCursorByRange(oUsedRange)
oCursor.GotoEndOfUsedArea(false)
' Obtain the last rows and colums in the "used" range from the cursor.
lastRow = oCursor.RangeAddress.EndRow
lastColumn = oCursor.RangeAddress.EndColumn
' Loop through all cells from the origin (0,0) to the last used column and row.
for row = 0 to lastRow
if (row mod 50 = 0) then
StatusBar "Rounding row " + (row + 1) + " of " + (lastRow + 1) + "..."
endif
for column = 0 to lastColumn
oCell = oSheet.getCellByPosition(column, row)
Select Case oCell.Type
Case com.sun.star.table.CellContentType.VALUE
' Only round value cells. Skip over empty cells, formuls and text.
roundedValue = Round(oCell.Value, placesToRound)
if (roundedValue <> oCell.Value) then
oCell.Value = roundedValue
endif
Case com.sun.star.table.CellContentType.EMPTY
Case com.sun.star.table.CellContentType.TEXT
Case com.sun.star.table.CellContentType.FORMULA
End Select
next column
next row
StatusBar "Rounding complete."
endif
End Sub
' Obtain access to worksheet functions, such as the "round" function.
Sub InitRound
if (oFunction is Nothing) then
oFunction = createUnoService("com.sun.star.sheet.FunctionAccess")
endif
End Sub
' Round the value to the given number of places after the decimal.
Function Round(value, decimalPlaces)
InitRound()
Dim args( 1 to 2 ) As Variant
args(1) = value
args(2) = decimalPlaces
Round = oFunction.callFunction( "round", args() )
End Function
global vStatusBarText as string '=text that is been displayed on the statusbar
sub StatusBar(optional vNewText, optional vAddText) 'set or add text to the statusbar, nothing = clear&reset it.
if isError(vNewText) then
if isError(vAddText) then 'clear statusbar
vStatusBarText=""
else 'add text to the previous statusbar
vStatusBarText=vStatusBarText & vAddText
endif
else
if isError(vAddText) then 'use new text
vStatusBarText=vNewText
else 'use new text and add the other text as well
vStatusBarText=vNewText & vAddText
endif
endif
vStatusBarText=right(vStatusBarText,int(ThisComponent.CurrentController.VisibleArea.Width/150)) 'Select last part that could be displayed.
if isNull(ThisComponent.CurrentController) then exit sub 'Because the last XEventListener-event can't be written to the statusbar, because it's no longer there!
if vStatusBarText="" then 'reset statusbar
ThisComponent.CurrentController.StatusIndicator.Reset
else 'change the text in the statusbar
ThisComponent.CurrentController.StatusIndicator.Start(vStatusBarText,0)
endif
end sub
更新: Round を書き直して、Calc を呼び出さないようにしました。これにより、速度が 2 倍になりました。まだ遅すぎます。1 秒あたり 50 行よりもはるかに優れている必要があります。
Function Round2(value, decimalPlaces) as Double
Round2 = Int(value * 10 ^ decimalPlaces + 0.5) / 10 ^ decimalPlaces
'Dim multiplier as Double, bigValue as Double
'multiplier = 10 ^ decimalPlaces
'bigValue = (value * multiplier) + 0.5
'Round2 = CDbl( CLng(bigValue) ) / multiplier
End Function
更新 2:
マクロの実行中に自動更新と画面の更新を無効にする方法が見つかりました。これにより、速度が再び 3 倍になります (現在は毎秒 200 行です)。
