Slow 1st time load of rtm file

rbuser

Hello All:

We are on Delphi 5/RB Enterprise Version 6.0.

The first time we run a .rtm file, it takes 5 to 8 seconds to calculate
the form. Every report after that runs about instantaneously.

What can be done to speed this up ??? I read in a previous thread that
the Ver 6 fixed this ( we were on version 5.56 ). There was something
mentioned about accessing the printer object too much.


Thank you.

What can I do to resolve this ???

Hi Neil,
I noticed an increased delay for my first report using v6.
The explanation has to do with the later loading of the
printer driver.

My work around:
1. Drop a report component on my opening screen
2. In On show, force the loading of the driver
with ppReport1 do begin
// next statement takes about 5 to 6 secs to execute
// any statement that requires the printer driver
// will work
ColumnWidth := ColumnWidth + 0.0;
end;
The time delay is not noticed in the startup of the application.

When the first report is called, the only delay is then just normal
for calculating the page.

HTH for the RTM case as well

I copies your code into my on show event but it has no effect on the 1st
time load speed of the ppreport1 component.

The 1st time delay is still long. Can you OR anybody at DIGITAL
METAPHORS give me any other idea how to trigger the load of the printer
driver ???

Thank you.

Neil,
I'm not sure that I understand. The ppReport1 component
that I suggested on the opening screen will exhibit the delay
(same as before). The only difference is that the delay is
exhibited at the application load (main screen).

Are you still finding that the delay occurs when you call up a
report after the main screen has loaded?

Jon:



YES

I pasted your code directly into my app in the on-show event. The
ppReport1 STILL has a 5-10 second delay on the first report. I timed on-show
and found that the property change had no effect on on-show speed.

I am running Windows 2000 which may make some difference as Win2000 has
some special characteristics with printer drivers.

It would be great if some of the digital Metaphors staff could comment
on this situation.

Hmmm! not sure as I use Win98
You might look at a previous thread where Nard addressed
the problem as I found it:
"Slow report load v6.0"
