Has
anyone looked at the source code for correcting this issue, if they have the
professional version?
We
currently use 2.0 registered version for some some software. I did a search for
GetTempPath in all of the source code and found only one file,
QRPRNTR.PAS
There
is a function in there defined as follows. This is the only reference to the API
call in this unit.
function TempFilename : string;
var
AName,
ADir :
array[0..80] of char;
{$ifndef win32}
ADrive :
char;
{$endif}
begin
{$ifdef win32}
GetTempPath(30,
adir);
GetTempFilename(aDir, PChar('QRP'), 0,
aName);
{$else}
ADrive := GetTempDrive(ADrive);
GetTempFilename(ADrive, PChar('QRP'), 0, aName);
{$endif}
result :=
StrPas(aName);
end;
Is
there any Borland documentation for the Quickreport thing?
Qusoft on their website says "We are not responsible
for the free version supplied with Delphi, Borland is" then on Borland's web
site, I can't find any documentation at all of the
problem.
Also
I am not very thrilled with Qusoft's explanation of the problem as saying
glibly that MS's long temp paths break lots of apps when all they had to do
was follow the API documentation. For the GetTempPath function it gives the
following:
"If
the function succeeds, the return value is the length, in characters, of the
string copied to lpBuffer, not including the terminating null character. If
the return value is greater than nBufferLength, the return value is the size
of the buffer required to hold the path. "
Buffer overruns are one of the most common errors
known to mankind :)
Taken from Windows 2000 Help ........
To
add or change the values of environment variables
- Open System
in Control Panel.
- On the Advanced tab, click Environment Variables, then
click the name of the user
or system variable you want to change, as follows:
- Click New to add a new variable name and value.
- Click Edit to change a current variable name and value.
- Click Delete to remove a variable name and value.
Notes
- If you are not logged on as
to the local computer, the only you can change are user variables.
- To
open a Control Panel item, click Start, point to Settings,
click Control Panel, and then double-click the appropriate
icon.
- Windows 2000 saves changes in the
so they are available automatically the next time you start your computer.
- You may have to close and reopen running programs for the new settings
to take effect.

How do you change the temp path in Windows
2000?
Just to back up what Nello and Craig have said,
I found this by searching Deja in
delphi.reporting-charting

shorter.
OK Craig and Nello
I'm going to be on site tomorrow and I'll check
those suggestions.
Sorry, Nello, for dismissing the Temp directory
pointer _ I did not realise that they were 'somehow
connected'!
Thanks for the input.

It would surprise me if the BDE version is in
play here (but being
surprised often is one of the charms of this
business <g> )
I vaguely recall that the "metafile problem" and
the "TEMP problem"
are somehow connected.
Some guesses to try ...
1. checking permissions on your TEMP
directory to insure you
aren't having a problem
accessing it
2. check that the path to your TMP and
TEMP dirs are not "too long"
I think there is a problem
about this.

Can't find an update newer than the one I have
(3.0.7) for QRStandard and D5.
There IS one for D6 but that is no good for
me.
Curious thing is that I am running Win2000 Pro
as my development machine, without this problem.
Question: If different workstations had
different versions of the BDE installed could this cause the
reported problem?

Metafile not valid
around last May I remember reading about 2 QR
problems
in Windows 2000. One had something
to do with TEMP files
and this was the other one.
ISTR QuSoft fixed both in a 2K update
available on their
website. Probably worth a
look. (www.qusoft.com ?)

Subject: [DUG]: Metafile

Hi
Have a site running a a Windows LAN and my
app based on Paradox.
They have recently upgraded one of their
workstations to Win2000 Pro (and I suspect added some other
software)
Now my app is generating an error message
whenever this user previews a report and tries to view the
second page.
The reports are QuickReports and the message
is "Metafile not valid".
Has anyone come across this before or
provide any insights as to where I might start
looking?
TIA
Mark
