[DUG] Copying files problem

Thu Sep 21 09:33:00 NZST 2006

On thinking about it there is no way in a program to alter the programs
working directory to be the destination folder....but I can do that in a
Shellexecute.

We get this sometimes.  Its as if the app has different access rights to the
user, even on Win2K.  We had an incident (still unresolved) a few days
ago.... Maybe its new windows updates.  One thing to note is that since
Win95 (at least), windows does the following :-

To Copy file from DirA to DirB

1.  Make DirB the current directory
2.  Copy from DirA
3.  Change back to original Current Directory

Sometimes, step 1 fails but there are no errors and it copies the file into
the current directory instead.  And I cant figure out any way to detect this
!!

I copy program files using a line like:

copyfile(Pchar(File1),Pchar(File2),false);

Sometimes this fails for no obvious reason (File2 is not in use for
instance), and if I open Windows explorer and copy from there it usually
works, if not if I delete the destination file and then paste works fine.
To my mind this proves it is not a problem with permissions to write into
this folder...

File1 is on the server, File2 is local on C drive.

any ideas?

Background:
This is a neat way of updating programs - updated exe files are loaded into
a central update folder (which is not used except for copying from), and the
startup program copies any updated programs into the local C drive working
folder before any programs are in use.   Works wonderfully except on one
site......I wonder the problem is from not being administrator or something
in the PC setup being locked down....(although I don't know why as Windows
Explorer works)

HI Jeremy, 

If you are incorporating this into an app, may I suggest you dynamically
instantiate the component each time you make an http call. I found this made
for greater reliability.
