Hey Mike,
I had to load up VFP Help to try to get on track with what you are
saying but I'm thinking of a couple of possible solutions:
1. There's a way of chaining reports together. You could run a report
for each sales person, but chain them together so it runs them and they
appear as one print job. I haven't ever really done this but it's worth
looking into. Look into the REPORT FORM ... [NOPAGEEJECT] and [NOEJECT]
options to see which ones will apply. I like the thought of this
approach as you're using the 'natural' report behavior, you're just
creating multiple reports programmaticly.
2. Another possible solution would be to pre-calculate how many records
will show per page, and then pre-populate a page number field, and a
page total field in the dataset before feeding the data to the report
itself. This would be reliant on a simple report layout. (No stretching
memo fields to mess things up, etc.)
3. You could do something crazy with the report listener, that would run
the report first to help you calculate the page totals per salesperson,
and then run the report again out to PREVIEW or the normal output. This
seems pretty complicated and would increase the time that is needed to
get the report output, but if this is what they want, then it's an
option. I used to do some of this but it has been a very very long time
and has been lost in the fog of my memory. Some experimentation would
tell you what is feasible.
Good luck and tell us how things progress along.

Executive Summary:
Anyone have a solution for "Page X of XX" where XX is reset when the
group-by changes on a VFP report?

All,
I have a report of sales grouped by Sales Person.
The page # resets as the group (Salesperson) changes... "Page 1"
"Page 2" "Page 1" etc. Works great.
My client wants it to show "Page 1 of 2" "Page 2 of 2" and then when
the group/salesperson changes, "Page 1 of 3" "Page 2 of 3" as
appropriate.
Using the "_PageTotal" system variable for an entire report works fine.
VFP does a double-run of the report to get the total # of pages...not
a problem.
But there's no way to reset it on the Group break (that I know of.)
So I Googled a "solution" for the Group _PageTotal problem, and it
works on my development computer.
When I run it on the client's workstation, it has a problem...I get
"File Not Found" when the function is called.
The solution I'm using is:
1. add a function call in the group footer band, i.e.,
"countpages(staffname,_pageno)"
2. add a column in the report source table "reportsource" to contain
the group page count, "ofpages"
3. create a function (I put it in my main startup application but it
works as a method on the calling form, too)
function countpages
parameter pStaffName, pOfPage
update dbf("reportsource") set OfPages = pOfPage where
allt(staffname)=allt(pStaffName)
return ''
endfunc
The problem is that when run on client's system (Win XP or Win7) I
get a "File not found" referring to the reportsource table reference
in the function call. It also includes a randomly generated file
name... due to reportsource being a cursor.
What I've tried:
1. Changed the reportsource from a cursor to a table
Select yadda yadda into TABLE reportsource (instead of
"into CURSOR reportsource")
This DID eliminate the "file not found" problem, but it also
caused the function to "fail" after just a few calls. In other words,
it acted okay, but the reportsource table only had about 7 of the
1,500 records updated (the ofpages field). The rest were still set to
0 (what they were initialized as.)
2. I moved the function from the main application file to a method on
the form that initiates the report activity.
No change.
3. I tried setting the datasession in the calling form, and in the
CountPages function.
No change. The datasessions are the same (based on WAIT windows I
added to popup and indicate the datasessionid at various steps.)
4. I double-checked the "Temp" workfile settings. Still not 100% sure
this is not the source of the problem.
I'm at a loss. Any ideas or is anyone successfully using a workaround
for the group+_pagetotal problem? I've read several articles,
including one by Cathy Pountny. Nothing so far...
Thanks for any pointers!
