Revision history for Perl extension Win32::OLE.

Changes in version 0.01-0.03 are by Gurusamy Sarathy. All other changes are by Jan Dubois unless attributed otherwise.

0.1709 April 17th 2008

• Get rid of "package Win32" statement in lib/OLE.pm because it confuses the CPAN indexer.

0.1708 April 17th 2008

• new version for separate upload to CPAN
• updated email addresses
• simplified Makefile.PL
• added META.yml
• additional casts to suppress compiler warnings under Win64
• added V_RECORD() and V_RECORDINFO macros for MinGW
• changed code to be conformant with ISO for() variable scoping rules

0.1707 unreleased, August 7th 2006

• add special support for tlbinf32.dll from Microsoft

0.1706 unreleased, June 8th 2006

• add support for receiving VT_RECORD and arrays of VT_RECORD
• improve error handling logic

0.1705 unreleased, March 28th 2006

• fix memory leak in Win32::OLE::Enum::All() and Win32::OLE::Enum::Next() (as a side effect collections containing undefined elements, like VT_NULL or VT_EMPTY variant, will be handled correctly)

0.1704 unreleased, November 28th 2005

• in ClearVariantObject() check IDispatch/IUnknown variants for NULL before calling Release() on them
• Win32::OLE::Const: check for 32 bit typelibs even in Win64 mode
• Don't load hidden or restricted types in Win32::OLE::Const. This fixes the "emptyenum redefined" problem with the "Microsoft Word" type library.

0.1703 September 6th 2005

• remove all USING_WIDE() codepaths
• use PTR2IV() and INT2PTR() macros
• make everything work with current cygwin

0.1702 unreleased, Sun, September 5th 2004

• fix freeing of VT_BYREF Win32::OLE::Variant objects

0.1701 unreleased, Thu, August 28th 2003

• add Win32::OLE->Option(Variant => 1) support

0.17 Mon, August 11th 2003

• add IsNothing and IsNullString predicate methods to Win32::OLE::Variant
• nullstring() variants used to be converted to undef. They are now converted to the empty string.

0.1604 unreleased, Thu, July 22nd 2003

• fix passing nullstring() as a parameter. VariantCopy() used to turn it back into an empty string.

0.1603 unreleased, Thu, March 4th 2003

• fix PL_dowarn test to only check the relevant bit

0.1602 unreleased, Thu, February 13th 2003

• Work around a Perl problem to support lvalue arguments to OLE method calls (e.g. substr() expressions). This will only work for PV lvalues, and not for IV lvalues (like pos()).

0.1601 Fri, November 22nd, 2002

• allow Variant(VT_VARIANT|VT_BYREF) as a shortcut for Variant(VT_VARIANT|VT_BYREF, Variant(VT_EMPTY))

0.16 Fri, October 18th, 2002

• Add Unicode support: passing Unicode strings to methods and properties as well as returning Unicode back to Perl works now
• Unicode::String objects can be passed to methods or assigned to properties
• Make Unicode support compatible with Perl 5.8
• Remove prototype checking from Win32::OLE::Forward() so that it works normally as an automation method too
• Fix compatibility problem ($AUTOLOAD munging) with Devel::DProf
• Add Win32::OLE::nullstring() method [alias for Variant(VT_BSTR)]
• Fix 2_variant.t tests for non-US locales
• Fix 3_ole.t test to not require write access to HKCR registry

0.1502 September, 7th 2001

• Only turn undef into VT_ERROR/DISPEPARAMNOTFOUND when used as a positional parameter in a method call. Otherwise turn it into VT_EMPTY.

0.1501 February, 6th 2001

• Don't clobber $1 etc. in AUTOLOAD. Unfortunately Perl doesn't set POK on the $1 SV, so we still cannot pass it to OLE methods. :(

0.15 Wed, December 6th, 2000

• Make sure the OLE browser works with IE5.5 and the latest ActivePerl
• Relax the checks for file existance in Win32::OLE::Const

0.1402 Mon, September 25th, 2000

• Fix potential crash during global cleanup when _Unique is set (by Rudi Farkas <rudolf.farkas@lecroy.com>)

0.1401 Mon, September 11th, 2000

• fix bug in GetMultiByteEx() sometimes chopping off the last byte

0.14 Tue, August 22th, 2000
