	Bugs Fixed:

		Fixed bug 63



	Changes made:



Build 3326:



	Bugs Fixed:

		Fixed bug 61



		Fixed problem with retrieving variants for columns of type byte,

		date/time and memo.



	Changes made:

        Added code which first attempts to get requested interface from the

        rowset when a call is made to IEntryID::GetInterface.



        Also, added preprocessor instructions to optionally remove emulation of

        IStream if not supported by rowset when calling IEntryID::GetInterface. 

        (just #define VD_DONT_IMPLEMENT_ISTREAM in stdafx.h)



        Changed code to send the following notification when an undo occurs:

	        dwEventWhat -> CURSOR_DBEVENT_CURRENT_ROW_CHANGED |

                           CURSOR_DBEVENT_CURRENT_ROW_DATA_CHANGED |

                           CURSOR_DBEVENT_NONCURRENT_ROW_DATA_CHANGED;

	        dwReason    -> CURSOR_DBREASON_REFRESH;



        Added code to check for required rowset properties.

        (they are DBPROP_IRowsetLocate and DBPROP_CANHOLDROWS)



        Moved firing of SyncAfter to DidEvent for reentrant safety.



Build 3313:



	Bugs Fixed:

		Added code to initialize variants before they are fetched to resolve

		a problem where Kagera did not return anything if the data was NULL.



		Fixed problem where DBGrid would fail to bind to certain datatypes.



		Fixed problem where DBGrid would get out-of-synch, because of our

		mishandling of beginning/end bookmarks.



	Changes made:



Build 3310:



	Bugs Fixed:

		Removed datatype coercion validation function, which caused problems

		by saying certain valid coercions were not allowed.



	Changes made:

		Changed updating functions so they do not call IRowsetUpdate::Update,

		rather they cache their changed in CVDCursorPosition, and call

		IRowsetChange::SetData when updated.



		Reduced size of release build by only expanding inline functions and

		disabling exception handling.



Build 3304:



	Bugs Fixed:

		Fixed string manipulation problems under Win95, where calls were made

		to unimplemented APIs (orginally discovered in phase I).



		Fixed bug where calls to ICursorMove::Move placed current row to the

		row after the last row fetched, rather than the last row fetched.



		Fixed bug where ICursorMove::Move generated notifications when caller

		fetched the current row only.



		Fixed bug in columns cursor, where returned string values/pointers where

		garbage, when the underlying value null.



		Removed hard-coded testing code, which always returned 174 from 

		ICursorScroll:GetApproximateCount.



		Fixed clean-up code in ICursorFind::FindByValues, which used fMemAllocated

		rather than fMemAllocated[ul].



		Fixed bug in CVDCursorMain::Create, where the variable propsetid was 

		initialized to have a guid {0, 0, 0, 0}, rather than being initialized 

		to DBPROPSET_ROWSET.



	Changes made:

		Changed column identifiers to always be type CURSOR_DBCOLKIND_GUID_NUMBER, 

		where the guid == CURSOR_GUID_NUMBERONLY and lNumber == ulCursorOrdinal.



		Added support for entryIDs.



Build 3227:



	Bugs Fixed: 

		Fixed bug that was disallowing coercion of bookmark columns to blobs for 

		CURSOR_DBTYPE_UI4.



		Fixed bug where CVDCursor::FetchAtBookmark was producing invalid bookmarks

		in the case where pBookmark was CURSOR_DBBMK_CURRENT and the status was

		VDBOOKMARKSTATUS_BEGINNING or VDBOOKMARKSTATUS_END.



		Fixed bug where notifications were coming out of CVDCursor::Move even when

		the bookmark was CURSOR_DBBMK_CURRENT and dlOffset was zero.



	Changes made:

		Completed ICursorUpdateARow methods for updating, adding and deleting



Build 3221:



	Bugs Fixed: 



	Changes made:

		Converted code to M10 OLE DB spec, these are the changes made:

			1.	included M10 headers

			2.	changed IRowsetNotify methods' first parameter to IRowset*

			3.	changed DBCOLUMNINFO cbMaxLength to ulColumnSize  

			4. modified code to pass NULL in IAccessor::ReleaseAccessor's new pcRefCount

			5. changed DBBINDING bPart to dwPart

			6. changed DBBINDING bMemOwner to dwMemOwner

			7. set IRowset::ReleaseRows' new rgRowOptions to NULL

			8. converted to new DBSTATUS codes

			9. changed IRowsetResynch::ResynchRows call to pass NULL in new parameters

		  10. linked with M10 libraries for new IIDs.



Build 3215:



	Bugs Fixed: 



	Changes made:

		Modified CVDCursor::ReCreateAccessors and CVDCursor::FillConsumersBuffer to create an use an array of accessors

		for retrieving out-of-line data.  Also, added a helper accessor which gets length and status information prior

		to retrieving true variable length data.  Fixed length data which is retrieved in out-of-line memory, (i.e. an

		I2 represented as a string) uses a table approach to obtain length information, since the length information 

		returned for these types using an accessor is number of bytes of the intrinsic type.  This change enabled us to

		optimized our allocations of out-of-line memory.



		Added code for getting extended metadata via the IColumnsRowset interface.



		Started implementation of ICursorUpdateARow methods for updating, none of these functions are complete however.
