I've noticed some slow down with VFP 9 reports, but what you are experiencing is wrong somehow. The report listener, GDI+ layer, etc... all constitute a performance hit and it is definitely noticeable, but what you are describing here is different. I mean, I've never seen a performance hit or size bloat anywhere close to the magnitude you are describing. How many pages, fields, detail bands, and headers are there on this report? Also, can you post the relevant code that you are using to actually preview the report? Have you unchecked the "save the printer environment" checkbox in the report's properties? Lastly, can you take a look inside the frx as a table and see what the heck is taking up all that space?

>After the debacle we all experienced years ago with the HP problem in VFP 3.0, I have a hard time believe the Microsoft would once again punish us on reporting performance. Yeah, the new features are cool to use but it is kind of like driving around in a brand spankin' new Porsche that maxes out at 30 miles per hour (48.28 km/hr!). So, what is going on with this and who signed me up for this torture?

>I have a report that in VFP 7 PREVIEWS (not even send it to the printer) in less than 2 seconds. The same report in 90 previews in a "smoke a cigarette" 262 (4 minutes, 22 seconds). Even running in 80 takes a long time. No pictures, no graphics, just text. There are some formulas that call VFP programs to retrieve data, etc. but it isn't anything major.

>In addition, if the user actually wants to PRINT, under 80 or 90 it sends a page, waits until the printer prints a page, sends another page, waits, etc. Crazy. Yes...the printer setting is set to spool so don't think i'm trippin out. The only thing that is "unique" is it is a local printer (wow) being sent over a LPT cable. Even printing over a network takes awhile. For those of you interested, the file size under 90 is 3.37 MB and under 7.0 it is 268kb.

>My users are royally ticked because they don't understand the "well you should see what this thing really CAN do". Don't get me wrong, I love VFP but this is absolutely crazy. Are there any solutions, tips, payoffs to this debacle or did i miss something in the help file?
