我正在使用此代码将一些数据从x工作簿复制到y工作簿。 x工作簿的大小为13 MB,Y为23.5 MB。从x复制数据并将其粘贴到y需要花费大量时间。无论如何,我可以让这个过程运行得更快吗?我正在使用上面的代码。谢谢

根据http://www.ozgrid.com/VBA/SpeedingUpVBACode.htm,以下内容可能会使您的代码更快(绕过剪贴板并直接复制值):
Sub test()
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.AskToUpdateLinks = False
Dim x As Workbook
Dim y As Workbook
Dim r1 As Range ' source
Dim r2 As Range ' destination
Set x = ActiveWorkbook
Set y = Workbooks.Open("S:\HR\Attendance Charts\2014\May 14\abc.xlsx")
Set r1 = y.Sheets("Report").Range("A34:DM64")
Set r2 = x.Sheets("Modified").Range("A70:DM100")
r2.Value = r1.Value '<<<<<<<<< this is the line that does the magic
y.Close
End Sub
检查我是否正确设置了范围r1
和r2

我改变了Floris的代码,尝试使用VBA数组
Sub test()
with Application
.ScreenUpdating = False
.DisplayAlerts = False
.AskToUpdateLinks = False
.enableevents=false
.calculation = Xlmanual
end with
Dim x As Workbook
Dim y As Workbook
Dim r1 As Range ' source
Dim r2 As Range ' destination
Dim Y_Array() as Variant
dim Y_Sheet as Worksheet
Dim X_Sheet as Worksheet
Set x = ActiveWorkbook
Set X_Sheet= x.Sheets("Modified") '=activesheet ' i've preferably named it with complete name here
'testing if y already opened, if it's the case win a lot of time
err.clear
on error resume next
Set y = Workbooks ("abc.xlsx")
if err<>0 then
err.clear
Set y = Workbooks.Open("S:\HR\Attendance Charts\2014\May 14\abc.xlsx")
end if
on error goto 0
with y
application.windows(.name).windowstate=xlminimized
set Y_Sheet= .Sheets("Report")
with Y_Sheet
Set r1 = .Range(.cells(34,1) , .cells(64,117) ) ' same as "A34:DM64")
with r1
redim Y_Array (1 to 30, 1 to 117) 'to make it a dynamic array : (1 to .rows.count, 1 to .columns.count)
Y_Array = .value2 'edit : modified to .value2
end with
end with
end with
Set r2 = x.Sheets("Modified").Range("A70:DM100")
r2.Value2 = Y_Array 'r1.Value '<<<<<<<<< this is the line that does the magic 'edit: modified to value2
y.Close
'Free memory
erase Y_Array
set r1=nothing
set Y_Sheet=nothing
set Y=nothing
set r2=nothing
set X_Sheet=nothing
set X=nothing
with Application
.ScreenUpdating = true 'uh, without reseting it to normal you gonna have troubles....
.DisplayAlerts = true
'.AskToUpdateLinks = true
.enableevents = true
.calculation = XlAutomatic
end with
End Sub
代码未经测试,不确定它真的有帮助,试一试......
