Problem with report preview

[zlaja]

Hi,

I am finishing my first application in delphi and I have to print my reports. My master table has between 100 000 and 500 000 records and I think there is the problem. Just for preview my report it takes between 5 and 15 minutes.
Is it normal?

thanks for any help!

A lot depends on the speed of your computer. Even with a fsat computer, previewing about 100,000 records means that there is going to have to be some processing. On my machine, with that amount of records, the first pages are displayed correctly while the other pages are being generated. You can see this by looking at the bottom left corner of the screen where you can see the number of pages rattling upto very high figures and not something you would really want to print. If it takes 15 or so minutes to preview that number of pages, how long is it going to take to print and how much ink and paper will it use??? Arte Et Labore
