folder access in "call shell..."

[Guest]

Hi.
Here is the code for a "backup" button

Private Sub buall_Click()

Call Shell("xcopy c:\dw\*.* H:\Dw\ /E /y")

Call Shell("xcopy h:\photo library\*.* H:\photo library\ /E
/y")

Call Shell("xcopy c:\darcy\graphics stuff\*.* H:\graphics
stuff\ /E /y")

End Sub

The first line runs OK but the other two don't

The backup external HDD (N is on/installed/working
The database is in c:\dw\

I have tried adding >backup.txt to the lines as I know that the volume of
data will take a while to copy (about 20gb). on the text file
C:backuplog.txt
C:dbase-menu-bg.bmp
C:help.bmp
C:krazydarcy-studiobase.ldb
C:krazydarcy-studiobase.mdb
C:logo--stensil copy.gif
C:logo--stensil.jpg
.....
All of the above files ARE in C:\dw\

Is access vba being sandboxed?
I want to be able to back up all three folders at the click of a button
I may end up using a batch file (.bat) and invoke that from the vb script.
But unsure if I will still hit the same problem.

Thanks for your time.

Because of the embedded spaces in the folder names, you need quotes around
the names. Note that to put a single double quote inside of a string, you
have to put two double quotes in a row:

Call Shell("xcopy ""h:\photo library\*.*"" ""H:\photo library\ /E /y""")

Call Shell("xcopy ""c:\darcy\graphics stuff\*.*"" ""H:\graphics stuff\ /E
/y""")

I have put the xcopy comand into a batch file and have got it to run for two
of the folders (2 of the xcopy commands).

I have discovered that the third is prematurly terminating because of a file
that causes a acess denied error in xcopy. I don't know why as I can
cut/paste it elsewhere. To discover this I first used a >buphotolib.txt on
the end of the xcopy command. This text file told me where the problem lied
not what it was. Then I had to enter the xcopy command in windows command
prompt window so I can see any error messages xcopy may give (call shell(...
doesn't give me a chance to read it.)

I hope this is the only file with this problem. Have just shifted it out and
will try the command again and see if it runs ok this time

prematurly terminating because of a file

that causes a acess denied error in xcopy.

Perhaps you could use a 'copy' command instead of xcopy?
(copy does not require exclusive locks)

Sometimes you can't xcopy things because they
aren't really there: Windows explorer is not
refreashed, or the BIT service is still doing
something with the file.

You're not, by any chance, trying to call all of this from the C:krazydarcy-
studiobase.mdb database, are you? I'm fairly certain you can't copy a db
while it's open.

Thanks guys.

The 1 1/2 dozen offending files were all .jpg's. So I manyally moved them to
a temp folder to "save as" in photoshop..

The way I went in the end was to call shell a .bat batch file which has the
xcopy commands in them. Each xcopy command generates a log text file So i
know it is working ok. I even use the /H /Y and for the changed/new files
backup a /D.
