|
|
|
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:

|
|
|
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.
