Hi,
I still test Pgdbe using Express library. Now I have problem with deleted records. I use a table, set scope with DC_SetScope(),
(for example, record #1 is not deleted, record #2 is deleted (in column __deleted is TRUE))
after DC_DbGoTop() only not deleted records are available (I test it wit DO WHILE !DC_EOF() .. DC_DbSKip(1).. ENDDO),
but when I create DCBROWSE, I see only one row with record #1 (OK) but when I display it, it's a record #2 !
What's wrong? (SET DELETED is ON, of course)

hi,

this is a Problem of pgDBE ISAM Emulation and not Express++
please report to Alaska Newsforum "preview.xbase++.20"

Jimmy, are you sure? These problem exist only if deleted record(s) is/are first or last record in selected scope.
If these are "inside scoped group" of records, are not visible (SET DELETED is ON!) and all works correctly. But
when deleted record is first (the same with last) in "scoped group" of records, after creation of DCBROWSE is
first not visible, but when I "stay" on first record and press "up arrow", I go to these deleted record. IMO, problem
is with corelation DbSetScope() - DbSkip() - Eof()/Bof()

I solved these problem. With DCBROWSE based on DC_XbpBrowse class from Express 252 works good (wrong was
DC_XbpBrowse class from Express 242). C'est la vie and now back to tests

I'm pretty sure Jimmy can't be sure. He doesn't use eXpress++. And scoping should work with Xbase++ 2.0 and SQL emulation, since it's a core functionality.

Take a look at your setting for "DC_ScopeExpress". Don't use it in that situation. Move to native DbSetScope() or call DC_SetScopeExpress(.F.).

it was not clear to me that you are using an old Express++ Version.

Jimmy,
with my DBF sources I work with Express++ version 242 - these was for me enough, I made in some Roger's sources changes
(for better support polish fonts). When I begin test with Xbase 2.0 first I recompile theseExpress sources, but when I have
some problem, I take another version (252) Express sources. But when I copy these to an temporary folder (in which was sources
from v242) during my changes not all of this was replaced with v252, especially - source code of DC_XbpBrowse class.
After I delete all these (mixed) source, copy all source code from v252, recompile DCLIPX - it work fine. IMO previous was conflict
source code version between DC_XbpBrowse and DC_SetScope

Piotr -

Why are you using such an old build of eXpress++ ?

The most current build is 259.
Build 260 will be available in 2 weeks.
I want to be sure to tackle all issues related to PGDBE before that release.

Roger,
I don't now if my software house have paid for last subscription. If it's possible, send me please (only for testing)
newer (current) version of DCLIPX.DLL and DCLIPX.LIB compiled with Xbase 2.0 on my private (dpiotr@interia.pl)
or bussines (sigid@sigid.pl) e-mail.
