问题描述
我创建了一个VBA代码,以删除初始计算所需的多余行和列,但在将csv转换/导入到数据库中之前必须将其删除.该代码循环遍历21张纸,并运行约4分钟.这是一个体面的运行时间还是可以缩短?〜谢谢
I've created a VBA code to delete extra rows and columns that were needed for initial calculations but are required to be removed before converting/importing a csv into a database. The code loops through 21 sheets and runs for about 4 minutes. Is this a decent run time or can it be shortened? ~Thanks

推荐答案
在下面的代码中
- 浓缩了操作码
- 停止屏幕更新和事件
- 在循环中逐行删除,并在AutoFilters中批量删除
Option Explicit
Public Sub RemoveTmpData()
Const WS_2COLS = "|IP-FSW|IP-2070|IP-MNTR|IP-BBS|IP-DET|IP-TTR|IP-CCTV|"
Dim ws As Worksheet
Application.ScreenUpdating = False
Application.EnableEvents = False
For Each ws In ThisWorkbook.Worksheets
ws.DisplayPageBreaks = False
ws.UsedRange.Value2 = ws.UsedRange.Value2 'convert formulas to values
If InStr(WS_2COLS, "|" & ws.Name & "|") > 0 Then ws.Columns("G:H").Delete
RemoveTmpRows ws.UsedRange, 2, 0 'remove rows with val 0, in col B
Next
With ThisWorkbook.Worksheets("IP-Unassigned")
RemoveTmpRows .UsedRange, 8, 1 'remove rows with val 1, in col H
.UsedRange.Columns("H:P").Delete
End With
Application.ScreenUpdating = True
Application.EnableEvents = True
End Sub
Private Sub RemoveTmpRows(ByRef rng As Range, ByVal colId As Long, ByVal crit As String)
With rng
.AutoFilter Field:=colId, Criteria1:=crit
If .Columns(colId).SpecialCells(xlCellTypeVisible).CountLarge > 1 Then
.Rows(1).Hidden = True
.SpecialCells(xlCellTypeVisible).EntireRow.Delete
.Rows(1).Hidden = False
End If
.AutoFilter
End With
End Sub
