Bulk update

Delphi 2009 was released so now it’s time to publish updates to my various units … In this article I’m just publishing the short changelog; you can expect more details on some enhancements (TGpJoinedStream, 4- and 8- aligned integer, Unicode support in GpStructuredStorage) in the near future.

DSiWin32 1.41

Compatible with Delphi 2009.
Created DSiInterlocked*64 family of functions by copying the code from http://qc.borland.com/wc/qcmain.aspx?d=6212. Functions were written by Will DeWitt Jr and are included with permission.
New functions DSiCopyFileAnimated, DSiConnectToNetworkResource, DSiIsHtmlFormatOnClipboard, DSiGetHtmlFormatFromClipboard, DSiCopyHtmlFormatToClipboard, DSiYield.
Added constants FILE_LIST_DIRECTORY, FILE_SHARE_FULL, FILE_ACTION_ADDED, FILE_ACTION_REMOVED, FILE_ACTION_MODIFIED, FILE_ACTION_RENAMED_OLD_NAME, FILE_ACTION_RENAMED_NEW_NAME.
Forced {$T-} as the code doesn't compile in {$T+} state.
Bug fixed: It was not possible to use DSiTimeGetTime64 in parallel from multiple threads

GpHugeFile 5.05a

Optimization: Under some circumstances, lots of unnecessary SetFilePointer calls were made.

GpLists 1.41

Works with Delphi 2009.

GpStreams 1.25

Added TGpJoinedStream class.
Span-storing class can now be modified via TGpScatteredStream.SpanClass.
TGpScatteredStream's AddSpan and AddSpanOS now return span offset in the span list.
Added bunch of BE_ overloads to the TGpStreamEnhancer class.
Small optimization in KeepStreamPositionWrapper destructor.

GpStructuredStorage 2.0

Works with Delphi 2009.
Added Unicode support to the underlying storage. File and folder names are stored in UTF-16, as are attribute names and values. API is still based on Delphi's 'string' type - meaning that values are converted to Unicode and back on the fly using the current locale.
Existing structured storage files will be upgraded automatically if they are not open for readonly access. Applications, compiled with GpStructuredStorage 1.x will not be able to read new/upgraded files. Version is incremented to 2.0.0.0 when 1.x file is opened unless it is opened in readonly mode. Newly created storages have version 2.0.0.0.

GpStuff 1.13

Implemented 4-aligned integer, TGp4AlignedInt.
Implemented 8-aligned integer, TGp8AlignedInt.
Added function OpenArrayToVarArray, written by Thomas Schubbauer.
ReverseWord/ReverseDWord rewritten in assembler (by GJ).
Declared MaxInt64 constant.

GpSync 1.21

Added optional external message counter to the message queue.

GpTextFile 4.01

Added TGpTextFile.Write(ws: WideString) and TGpTextFile.Writeln(s: string) overloads.
TGpTextFile.Write[ln] string parameters made 'const'.
Bug fixed [found by AKi]: TGpTextFile.Write was not working when using CP_UTF8 codepage.
