Delphi 7.1 Update Release Notes=======================================================This file contains important supplemental and late-breakinginformation that may not appear in the main productdocumentation, and supersedes information contained in otherdocuments, including previously installed release notes.Borland recommends that you read this file in its entirety.NOTE: If you are updating a localized version of Delphi 7, visit the Borland Registered User web site to obtain a localized readme file that may contain important late- breaking information not included in this readme file.IMPORTANT: Delphi must be closed before installing this update. =====================================================CONTENTS * INSTALLING THIS UPDATE * UPDATING LOCALIZED VERSIONS OF DELPHI 7 * KNOWN ISSUES * ISSUES ADDRESSED BY THIS UPDATE - IDE - CORE DATABASE - DATASNAP - DBGO (ADO COMPONENTS) - dbExpress - dbExpress COMPONENTS AND DB VCL - dbExpress CORE DRIVER AND METADATA - dbExpress VENDOR ISSUES - dbExpress CERTIFICATION - WEB SNAP - ACTIVEX - COMPILER - RTL - VCL - THIRD PARTY - BOLD FOR DELPHI * 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: LibDebugSqlConst.dcu LibSqlConst.dcu SourceVclSqlConst.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 FilesCommon FilesBorland SharedDBExpress. * 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 Delphi7Help 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 UPDATEThis readme lists the maintenance for all editions of Delphi 7;not all of the features mentioned in this file are available inall 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 as type variant." * TClientDataSet doesn‘t save data to file when FileName is set and there is no existing file on disk (Quality Central 2307). * Using the Delphi 7 version of midas.dll to open an XML file that was saved with the Delphi 6 version of midas.dll results in an illegal operation. * Incorrect filter expression parsing occurs when parsing a value that contains a quote in TClientDataSet. The expression parser incorrectly treats the rest of the expression as a formula (Quality Central 1266). * TClientDataSet.ChangeCount will return an incorrect value when editing the value of a TStringField or a TWideStringField and then reverting it to the original value (Quality Central 2717 & 4508). * Canceling an update to an individual field by assigning the "unassigned" (varEmpty) value to TField.NewValue in the TDataSetProvider.BeforeUpdateRecord event handler does not work (Quality Central 3660). * TClientDataset InternalCalc fields are reset to null after calling the ApplyUpdates method when using poPropogateChanges (Quality Central 3777). * When using incremental fetching on a TClientDataset with parameters, the associated TDatasetProvider will repeatedly return the same set of records (Quality Central 3515). * TClientDataset.FindKey will fail with an list index error when used on a cloned nested dataset (Quality Central 3786). * When the size of a Persistent field in TClientDataSet is set too large, it overwrites neighboring fields upon Post (Quality Central 3974). * TDataSetProvider generates incorrect SQL in response to a RefreshRecord request in some cases and fails to update all fields properly (Quality Central 4014). * When TDataSetProvider obtains the DB ‘current‘ values after an update conflict, it does so against the wrong fields (Quality Central 4006). * TClientDataSet.Delete fails with the error "Cannot delete master record with details" even when all of the details are deleted if the detail table was previously cloned (Quality Central 5646). * In some cases, records may disappear from a nested TClientDataset after performing edits, applying updates and calling refresh (Quality Central 7287). * When multiple indexes are included with the data from a provider, the IndexDef entries in the TClientDataset will show duplicate ‘Fields‘ and ‘DescFields‘ values (Quality Central 7543). * When updating blob fields in a TClientDataset with the LogChanges property set to False, blob data is lost from other unrelated records (Quality Central 6591). * Using a Filter or Locate with a TLargeIntField on a TClientDataSet will always fail with the error "Constant is not correct type". (Quality Central 6142 & 3496). * Calling the CancelRange method on nested TClientDataset will cause all records for every master record to be displayed (Quality Central 4301). * When using RefreshRecord on a Memo or Blobfield and the field has been modified by another user, the blobsize of that field does not change if it is less than before (Quality Central 4676).* Calling the TClientDataset.Locate method on a TWordField always returns false (Quality Central 5319).* Using the TDataSetProvider poFetchDetailsOnDemand option with a server-side master/detail definition (nested dataset on the client side) raises an exception when the master TClientDataset is opened (Quality Central 5707).* TClientDataset may create an incorrect delta when inserting new master and detail records and then editing the same master record a second time (Quality Central 6849). * The assignment of a LargeInt field to another LargeInt field fails when the destination and source are both TLargeIntFields (Quality Central 6393).* When Params are passed from a TClientDataSet to a TDatasetProvider, the Size,Precision, and NumericScale property settings are lost (Quality Central 6308). * TClientDataSet allocates values against nested dataset AutoInc fields but it should not (Quality Central 5509).* When using a TimeStamp type parameter with a TClientDataSet an error occurs when the parameter is passed to the server (Quality Central 6372). * Setting MTSDataModule.AutoComplete to False in the IDE is overridden and set back to True at run time (Quality Central 4716).* Calls to ApplyUpdates(-1) on a TMTSDataModule do not work properly (Quality Central 6906). =======================================================DBGO (ADO Components)* Using TParameter.Assign(TParam) or TParam.Assign(TParameter) causes incorrect settings of the Size, NumericScale, and Precision properties (Quality Central 6366). * When values in persistent TMemoFields are returned after reading a row of a TADOTable, the values are truncated at the first occurrence of #0 (Quality Central 2771). * When using TADOQuery to get a result set from a SQL query, the SQL statement gets prepared but never gets unprepared Quality Central 3635). * With a query, when using cursorType set to ctOpenForwardOnly and cursorLocation set to clUseServer, the "First" method will move the cursor position to the second record (Quality Central 4769). * Setting the value of a TLargeInt field to a negative value in an ADODataSet and calling Post results in the error "Multiple- step operation generated errors. Check each status value" (Quality Central 2106). * When using a SQL Server 2000 table with a BigInt or decimal columns, negative values are incorrectly returned as positive values by ADO components (Quality Central 2379 & 998).=======================================================dbExpress COMPONENTS* When including the line delimiter ";" at the end of a select statement in TSQLQuery, then using the query and a TDataProvider to give data to a CDS, you cannot apply updates without encountering a the syntax error "Token unknown."* Updating on a TSQLQuery with either a WHERE clause or when adding a delimiter ";" results in the error "Unable to find record, no key specified." * When using TSQLConnection and TSimpleDataSet to access a MySQL database, it is impossible to add new records to a table that has an auto-increment primary key (Quality Central 5465). * When using the MySql driver, erroneous state information about the number of active statements with respect to a TSQLConnection might result in a transaction starting on one connection and a commit or rollback happening on another connection (Quality Central 1074). * Updating on TSQLQuery with either a WHERE clause or when adding a delimiter ";" results in the error "Unable to find record, no key specified" (Quality Central 5550). * When using TSQLQuery to add calculated fields, OnCalcFields fails on the first record, because all of the fields in the first record are empty after OnCalcFields is called (Quality Central 1328). * Calling TSQLConnection.getTableNames() to retrieve system tables takes too long.* Using TSQLConnection.CloneConnection may result in the loss of the TableScope status for a new connection (Quality Central 5867).=======================================================dbExpress CORE DRIVER AND METADATA* DB2 V8 Support - Index Metadata retrieval: (Quality Central 4150) Querying for a table with a unique index fails with "Cannot convert a variant of type (Null) to type (String)"* DB2 V8 Support - Fetching a stored procedure parameter fails.* MySQL 4.0.x support (Quality Central 3731).* MySQL driver supports only the default Port (Quality Central 3736).* MySQL SQLCommand.GetRowsAffected returns 0 on successful updates (Quality Central 4504).* MySQL TimeStamp comes back as NOT NULL always (Quality Central 4689).* MySQL metadata causing data truncation (Quality Central 4160).* AV on SQLCommand.Close() in MySQL driver (Quality Central 5819).* MySQL metadata is retrieved from wrong database (Quality Central 4130).* An MSSQL stored procedure with long names causes memory corruption (Quality Central 3225).* The MSSQL driver leaks resources on repeated SQL execution (Quality Central 4059).* MSSQL TimeStamp fraction part rounding error while fetching data.* MSSQL - ExecDirect() does not return the RowsAffected.* MSSQL return parameter is not available from a stored procedure returning cursor/cursors (Quality Central 3763).* An MSSQL stored procedure with no parameters causes memory corruption.* An MSSQL stored procedure does not return @@IDENTITY after a SP execution. The identity value is returned only on the third execution.* ORACLE Functions are now supported (Quality Central 4051).* ORACLE SQLCommand.getParameter() always returns the NULL indicator as True (Quality Central 4018).* InterBase - Support for BOOLEAN data type has been added.=======================================================dbExpress VENDOR ISSUES* MySQL - Data truncation resulted as the cursor level metadata is incorrect. MySQLField.length is 1024 for the second columns after describing the SQL "Show create table tablename". - (Quality Central - 1810)* MSSQL - SubQuery parameter binding causes an AV in MSVCRT7.DLL (Quality Central 2767) - MS bug. Case # SRX030728604937.* MSSQL Null parameter binding on a NOT NULL INTEGER columns fails with a SQL Error "SQL State:HY000, SQLError Code:0 Invalid input parameter values" - MS bug Case #SRX030728605044. dbExpress MSSQL driver calls IDBCommand.Prepare() and that seems to cause this bug in SQLOLEDB.DLL.=======================================================dbExpress CERTIFICATIONdbExpress has been certified with the following databaseversions:InterBase 7.1 (*Driver should also work with InterBase 6.5, 7.0)Oracle 9.1.0 (*Driver should also work with ORACLE 9.2.0)DB2 UDB 8.x (*Driver should also work with DB2 V7)MSSQL 2000Informix 9.xMySQL 4.0.18 * The driver should work with these database versions, however, it has not been fully certified with these versions. =======================================================INTERNET/WEBSNAP* Procedure TSockWebResponse.SendResponse contains code that causes an incomplete response. =======================================================ACTIVEX* On Windows 98 SE, registering an OLE-server on a a shared mapped drive and then starting the program from a non-UNC path drive results in an endless loop (Quality Central 3151). * ShortToLongFileName fails on some UNC paths, which makes TComServer fail when the executable is located on a remote computer (Quality Central 3049). * Additional methods begin with GhostMethod_ are added to interface declarations which would not appear in Delphi 6 (Quality Central 3426). * SetOlePicture distorts the target TPicture size (Quality Central 4137).======================================================= COMPILER* Assigning a partially empty multi-dimensional dynamic array to a variant causes an access violation. * Converting an empty dynamic array to a variant array results in a non-empty variant array with the wrong bounds. * Assert fails to break and leaves an FPU invalid op exception set (Quality Central 5248). * Under some circumstances, optimization causes an access violation on a call to a dynamic + safecall method (Quality Central 5071). =======================================================RTL* In System.pas, function LoadResString(ResStringRec: PResStringRec): string; has a hard-coded buffer of 1024 characters, which causes resource string table entries in excess of 1023 characters to be truncated (Quality Central 7581). * On Windows Server 2003, calls to SysUtils.GetEnvironmentVariable fail with an access violation wHen the requested environment variable does not exist (Quality Central 4319). * When a variant array item is a string with embedded null characters (#0), Delphi treats those items as null-terminated strings when the string is assigned to an item of variant array (Quality Central 6078). =======================================================VCL* Context and keyword help does not fire for the OnHelp events.* Selecting a zero length (empty) item in drop-down combo box results in an access violation in ntdll.dll. * Attempting to delete a single item from the TComboBoxEx ItemEx list, that item and the next item are deleted (Quality Central 3991). * Calling TBitmap.Assign(nil) may result in a GDI resource leak (Quality Central 2511). * TRegistry class leaks a register key handle if LazyWrite is set to False. * THashedStringList ignores the NameValueSeparator property (Quality Central 5632). * In a DBCS environment, an exe filename that includes DBCS characters often garbles Application.Title (Quality Central 5089). * Menu items and images are sometimes drawn partially in black on Windows XP systems that have themes disabled (Quality Central 2341). * When the ValueListEditor Visible property is set to False, making it visible and adding a string at runtime may cause an access violation (Quality Central 4953). * When connected to a network printer and the system hosting the network printer is offline, Printer.PageWidth may cause an access violation in GDI32.DLL (Quality Central 757).* The OldCreateOrder property for a form that inherits from another form is automatically set to True when the form is saved (Quality Central 1675). * When ending a Windows session (either by using Log Off or Shut Down) while a VCL-based Delphi application is running, no OnDestroy events on the application‘s forms are called, nor are any finalization sections executed. This may result in lost data and user settings (Quality Central 5332). ======================================================= THIRD PARTY - BOLD FOR DELPHI* SQLDatabaseConfig now contains settings for database evolution scripts (separator, terminator and commands for transaction start/commit). Logs can be saved from the evolution dialog (Quality Central 4679). * BoldSelectChangeAction in BoldComboBox is now triggered more appropriately on incremental searches (Quality Central 2827).* A potential infinite recursion problem in TBoldUnOrderedIndexableList.KnowsSupportsNil has been fixed.* An assert with side-effects in TBoldObjectList.GetBoldObject has been changed. This affects debug dcus only.* TBoldUMLModelValidator.ValidateClass no longer has a bad format string for one error. * TBoldDbDataValidator.Validate no longer validates without running any tests when not connected to a database.* DBDataValidation no longer fails on parent or child mapped classes. * Performance of XMI Import has been improved (Quality Central 2827) .* XMI Export now correctly exports multiplicity 0..n. * Transaction grouping in optimistic locking has been improved by performing checks in the same transaction as the update (Quality Central 3123).* A memory leak in the Object Lending Library has been fixed (Quality Central 3648).* Several issues with BoldGrid and goTabs have been resolved (Quality Central 3903 and 3904).* Saving modified multilinks no longer yields an index out of bounds condition under certain conditions (Quality Central 4870).* BoldSystemDebuggerForm no longer yields an access violation on the second invocation from a Bold Action (Quality Central 6482).* Certain combinations of tableMapping=Child and abstract classes have been improved (Quality Central 7110).* The OCL operation includesAll no longer returns false when it should return true (Quality Central 3146).* An Import problem with "Error: Class is already a relation class for another association" has been fixed (Quality Central 3093).* TBoldEnvironmentConfiguration.DeactivateQueue no longer yields an access violation during finalization (Quality Central 3227).* An access violation in BoldMemoryManager during finalization of multi-threaded applications has been fixed.* Model validation no longer incorrectly warns against parent mapped classes with derived attributes not allowing null.* Relating objects belonging to different Bold systems is no longer allowed.* Instructions for compiling IDL files have been improved. =======================================================VERIFYING THAT THE UPDATE WAS SUCCESSFULThe final dialog of the update installer indicates whether theupdate was successful. You can also:* Open Delphi 7 and use "Help | About" to display the About Box. The product version should be: Version 7.0 (Build 8.1) (Before applying the update, the version is 7.0 (Build 4.453).) * Use the file list in "FILES INSTALLED BY THIS UPDATE" below to verify that the correct file versions are installed on your machine. =======================================================FILES INSTALLED BY THIS UPDATEThis update adds or updates the following Delphi files.
