creating a dos command in VBE

[norika]

Hi all experts,

I am new to excel VBA, and need some help in this topic.

I got a excel data file , and its data would be changed day by day. In order
to trace mistakes and backup reason, I'm going to create some vba coding to
make a backup file in the same directory if I pressed a custom button in my
tool bar.

I create a stupid macro to save the active orginial file to another file
name, but after the code finish running, the existing file already replaced
by new file, because I used "SAVE AS" function in my coding.

What should I do if I just want an to copy my existing file to the same
directory?

Is it possible to run a dos command like " copy xxx.xls yyy.xls" in VBA?


Best Regards,


Newbie.

dayname = CStr(Day(Now()))
monthname = getmonth(Month(Now()))
sfilename1 = "Semi_Bup_" & dayname & monthname
sfilename2 = ".xls"
fullname = sfilename1 & sfilename2

ActiveWorkbook.SaveAs Filename:=(spath & fullname), _
FileFormat:=xlNormal, Password:="", _

Look at the SaveCopyAs method.
