* VERIFYING THAT THE UPDATE WAS SUCCESSFUL
* FILES INSTALLED BY THIS UPDATE
=======================================================
INSTALLING THIS UPDATE
* This update can not be applied to Delphi 7 Architect Trial
version.
* This update can not be removed after it is installed.
* You will need the original Delphi 7 installation CD available
to install this update.
* To install this update from the CD, insert the CD, and launch
the d7_ent_upd1.exe file appropriate for your locale.
* To install this update from the Web, double-click the
self-executing installation file and follow the prompts.
* The Delphi 7 documentation PDF files are available on
the update CD.
========================================================
UPDATING LOCALIZED VERSIONS OF DELPHI 7
* This update can be applied only to the English version of
Delphi 7. There are separate updates for the German, French
and Japanese versions of Delphi 7.
* This update provides new localized versions of the SqlConst
files. After installing the update, backup and delete the
following files from the Delphi 7 installation folder:
Lib\Debug\SqlConst.dcu
Lib\SqlConst.dcu
Source\Vcl\SqlConst.pas
and then remove the appropriate locale extension (.de, .fr, or
.jp) from the new SqlConst files in the same folders. For
example, for the French version of Delphi, rename
SqlConst.dcu.fr to SqlConst.dcu.
========================================================
KNOWN ISSUES
* dbExpress driver - After installing this update, the
dbxdrivers.ini file will not contain an entry for MSSQL=1. If
you require that entry, please edit the ini file manually
after installing the update. By default, dbxdrivers.ini is
located at C:\Program Files\Common Files\Borland
Shared\DBExpress.
* If you have updated any Borland packages in the system32
directory with unofficial patches or updates from CodeCentral,
MSI might revert (auto-repair) those packages to their
previous version during installation of this update.
Therefore, after installing this update, you may need to
re-install unofficial patches or updates.
* Due to a Windows Help engine limitation on Windows 98 and
Millennium, the Help system Index tab will be empty if the
index exceeds 32,767 keywords.
If you encounter an empty Help Index tab after installing this
update, open the d7.ohi file in the Delphi7\Help folder and
comment out one or more of the index entries by changing the
colon in column one to a semi-colon, as shown here:
;Index Open Tools API (IOTA)=d7iota.hlp
Save the d7.ohi file and delete any hidden *.GID files in your
Delphi7/Help folder before restarting the Help.
This modification reduces the number of index keywords, but
does not affect other Help system functionality, such as
cross-file linking or F1 accessibility.
========================================================
ISSUES ADDRESSED BY THIS UPDATE
This readme lists the maintenance for all editions of Delphi 7;
not all of the features mentioned in this file are available in
all editions of the product.
This update resolves the following issues:
IDE
* Using the up/down arrow keys to navigate and select items from
the Code Completion window sometimes skips items (Quality
Central 2875).
* In the Project Manager, units are incorrectly displayed in the
order that they are listed in the USES clause, rather than
alphabetically.
* Using collections containing component references and form
inheritance can result in incorrect references being stored in
the dfm file.
=======================================================
CORE DATABASE
* TFMTBCDField initializes to size 8 instead of size 4, allowing
the system to initialize precision to 7 and size to 8
(Quality Central 5938).
* Using a TDBLookupComboBox to display a list of data given
by a detail TQuery results in the error "Field '' not found"
(Quality Central 5384 and 4823).
* TDBRadioGroup maintains its focus on the most recently
selected item, even after an edit has been canceled
(Quality Central 2109).
=======================================================
DATASNAP
* After deleting a row from a TClientDataset, sometimes the
delta dataset still contains a record. This happens if you
populate the Nested Dataset field before populating another
field that precedes it in the field order.
* The TClientDataSet.ApplyUpdates method fails if the dataset
contains only changes to fields that have the
ProviderFlags.pfnUpdate property set to False
(Quality Central 2338).
* TClientDataSet does not order correctly on a TLargeIntField
when used in an index or in the IndexFieldNames property
(Quality Central 1050 & 2626)
* TAggregateField returns an incorrect value after a
filter was used and then cleared (Quality Central 1712).
* A "Key violation" exception may incorrectly be generated
when using poFetchDetailsOnDemand with a nested dataset that
also has an InternalCalc field (Quality Central 2011).
* TClientDataSet may contain invalid Delta entries when using
poPropogateChanges. (Quality Central 2019 & 2333).
* Editing the value of an InternalCalc field on a nested
TClientDataset causes the ChangeCount property of the
parent dataset to increase (Quality Central 2027).
* A TLargeIntField cannot be used as a linking field in a
master/detail relationship. Doing so results in the
error "Cannot access field
