Welcome. Just wish I could find you the good version of that, but it seems
to have disappeared from my archives. The good version of it used named
pipes instead of a disk file. I resorted to named pipes in the end because
GetTempPath would fail on some (10%) of the server systems I encountered

Does anyone have a way to determine whether the file HARBOR.TXT
has been released for reading after being completely written? I would
be able to fix this problem by replacing the Sleep(500) with a loop
that tests till the HARBOR.TXT file is ready for reading, having

Thanks Stephen,
I found a web page with a similar snippet, and so I was able to
get the following to work in my OnFormCreate handler:
D := GetStartDir;
ShellExecute( 0, 'open', PChar('command.com'),
PChar('/c '+'ipconfig/all
I managed to set a flag, then loop on exceptions with a LoadFromFile)
until there was no exception, and that seems to solve the problem!
Thanks Sid,

I haven't tried this, but probably what you can do is try to open the
file exclusively (fmShareExclusive). If it is in use by DOS, then
the open should fail. Once DOS finishes and closes the file, the
open should succeed. So something like this:
waiting := 100;
repeat
try
fs :=
Thanks Wim! I finally got it figured out.

But actually, I did get one to work. It finally gelled for the following
code in my OnFormCreate handler:
D := GetStartDir;
ShellExecute( 0, 'open', PChar('command.com'),
PChar('/c '+'ipconfig/all harbor.txt'),
nil, SW_HIDE );
