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!
