BUG: OleCreateLinkFromFile Fails on CD-ROM-Based File
In an OLE client application, the
OleCreateLinkFromFile function returns the value OLE_ERROR_DRIVE.
BUG: DIB Can Be Returned Only on TYMED_HGLOBAL
IDataObject::GetData returns DV_E_FORMATETC when requesting a
device-independent bitmap (DIB) from an OLE object.
BUG: SR2TEST GP Faults During Object Shutdown
A general protection (GP) fault occurs when calling IOleObject::Close()
on an SR2TEST object.
BUG: (I)CntrOutl Does Not Set Target Device Information
During the print process from (I)CntrOutl, a server application is asked to
render its display with the TARGETDEVICE structure set to NULL instead of
containing a valid structure. This implies that (I)CntrOutl wants a screen
representation rather than a printed representation of the object.
BUG: Accelerator Causes Crash in ISvrOutl Embedded in C12Test
After embedding an ISvrOutl object in Cl2Test, pressing the ALT+BACKSPACE
accelerator (Undo) results in a general protection (GP) fault within
ISvrOutl.
BUG: Insert Object from Zero Length File Causes GP Fault
Creating an object from a zero length file that does not have a valid file
class extension results in a general protection (GP) fault after displaying
the message, "Not enough memory to perform this operation. Close one or
more applications and try again."
BUG: Set Line Height on ISvrOutl Object Causes GPF in Cl2Test
In certain circumstances, editing the Line Height of an ISvrOutl object
embedded within Cl2Test results in a general protection (GP) fault after
displaying the following message:
GDI - An error has occurred in your application. If you choose Ignore,
you should save your work in a new file. If you choose Close, your
application will terminate.
BUG: Deleting an Open Packager Ojbect Causes GP Fault
Deleting an object from within the Object Packager results in a general
protection (GP) fault.
BUG: Cannot Paste Link SR2TEST Object in OLE 1.0 Client
The Paste Link option is not available in an OLE 1.0 client application
after copying an unsaved SR2TEST object to the clipboard.
BUG: SR2TEST Won't Close After Editing Link Object
After editing a linked SR2TEST object from CL2TEST, SR2TEST fails to shut
down after first displaying the following message box:
Error Document not unlocked. Attempt Self-unlocking?
BUG: Paste Link Disabled Across the Network
The OleQueryLinkFromData application programming interface (API) function
returns failure when clipbook data from another machine is copied to the
local clipboard, even if the clipbook contains all of the data needed to
create a link.
BUG: Object Packager GPFs w/Paths Greater Than 64 Characters
Packaging an object that has a fully qualified path of more than 64 letters
results in a general protection (GP) fault in the Object Packager.
BUG: Status Bar Not Redrawn With SR2TEST When In-Place
After inserting an SR2TEST object into the in-place version of the OUTLINE
sample application, the status bar will not be redrawn until the container
application's window is resized.
BUG: Cursor Does Not Update with Sr2Test and ICntOutl
After inserting an Sr2Test object within the in-place Outline sample
application, cursor display is not handled correctly when the cursor is
positioned over the in-place object.
BUG: OleCreate and IOleCache::Cache Fail with Multiple TYMEDs
The OLE 2.01 creation functions [OleCreate(), OleCreateFromData(), and so
forth] and IOleCache::Cache() fail if multiple values are specified for the
TYMED field of the FORMATETC parameter. The functions fail even if the
object server supports at least one of the TYMED values specified.
BUG: IROT::IsRunning() Returns S_FALSE for OLE 1.0 Servers
When an OLE 2.01 container application calls
IRunningObjectTable::IsRunning() on the moniker for a linked OLE 1.0
object, IsRunning() returns S_FALSE even if that OLE 1.0 object is already
running.
BUG: Retaining Clipboard IDataObject Causes Unexpected Result
An application holding on to a clipboard IDataObject pointer, and making
repeated calls to IDataObject::EnumFormatEtc() through that pointer, may
find that the set of formats returned by EnumFormatEtc() changes between
calls.
BUG: SR2TEST Menu Items Enabled Incorrectly
During an in-place activation session, SR2TEST sometimes incorrectly
enables menu items on its Edit menu.
BUG: OLE 2.0 Containers & 1.0 Objects that Close w/out Saving
When an OLE 1.0 object is inserted into an OLE 2.0 container document and
then closed without an update being invoked, the correct streams for that
object are not written to storage. Any subsequent attempt by the container
to load the object will fail.
BUG: CL2TEST Fails to Parse Filenames with Extended Characters
When attempting to insert a new embedded object from a file, CL2TEST fails
with the error STG_E_FILENOTFOUND if the filename or directory name
provided contains an extended character.
BUG: Insertion of Large .WAV Object Fails
In some cases, inserting a large .WAV file object into either an OLE 1.0 or
OLE 2.0 container will fail.
BUG: OLE 2.01 Does Not Support CF_OWNERDISPLAY
If an application places a data transfer object onto the clipboard and that
data object enumerates CF_OWNERDISPLAY as one of the clipboard formats, the
application will not receive the WM_PAINTCLIPBOARD message.
BUG: IOleCache::Cache Returns Incorrect Error Value
An OLE 2.0 container application calls IOleCache::Cache for a particular
FORMATETC and is returned the value OLE_S_FORMATETC_NOTSUPPORTED. A
subsequent call to IOleCache::Cache with the same FORMATETC returns
CACHE_S_SAMECACHE.
BUG: OLERENDER_ASIS Results in Blank Embedded Object
If an OLE 1.0 client application contains an embedded object and copies the
object to the clipboard and an OLE 2.0 container application then performs
a paste operation by creating a new embedded object based on the clipboard
data by calling OleGetClipboard() and then calling OleCreateFromData(), the
resulting embedded object appears blank in the container's document if the
OLE 2.0 container specifies OLERENDER_ASIS as the renderOpt parameter to
OleCreateFromData().
BUG: Invisible MSDRAW Object Retains Keyboard Focus
When an invisible MSDRAW object is inserted as an OLE embedded object,
the object retains the keyboard focus. This behaviour is incorrect. The
MSDRAW object should not take the focus until it has been made visible.
This problem occurs whether the MSDRAW object is inserted into an
OLE 1.0 client application or into an OLE 2.0 container application.
BUG: Iconic OLE Object Prints as Black Rectangle on PostScript
Calling OleDraw() or IViewObject::Draw() to print an iconic OLE object to a
PostScript printer results in a black rectangle being drawn.
BUG: First Entry in Paste Special Dialog Is Blank
The first format entry in the Paste Special dialog box is blank after
copying an OLE2Link object from an OLE 1.0 client to the clipboard.
NOTE: An OLE2Link object is created by the OLE 1.0 compatibility layer when
an OLE 2.0 link is copied from an OLE 2.0 application to the clipboard, and
then pasted into an OLE 1.0 client application.
BUG: IEnumUnknown Is Not Remoted
All calls to IOleContainer::EnumObjects() fail.
BUG: SVROUTL Link Not Displayed Correctly in CNTROUTL
Selecting the Paste Link menu item in the CNTROUTL sample application does
not correctly display the contents of the link if the source application is
the SVROUTL sample application.
This problem occurs only if the information created in SVROUTL is edited
further after the Edit Copy operation in SVROUTL, but before the Paste Link
operation in CNTROUTL. In this situation, the resulting link object is
displayed as originally copied to the clipboard, and does not reflect the
changes made after the copy operation.
PRB: Embedded Object's Size Changes When it Is Run
A non-running embedded object is resized in an OLE 2.01 container
application. The next time the object is run, it snaps back to its previous
size.
BUG: CL2TEST Does Not Display Prompt String from GetCurFile()
IPersistFile::GetCurFile() returns S_FALSE to indicate that the document
has no currently associated file. In this case, GetCurFile() returns the
default prompt string for the filename (as would be displayed in the Save
As dialog box under the File menu) in the lplpszFileName parameter.
When CL2TEST calls IPersistFile::GetCurFile(), and GetCurFile() returns
S_FALSE, CL2TEST fails to display the returned prompt string.
BUG: CL2TEST Handles Icon Aspect Incorrectly
Selecting the iconic aspect when inserting an object in CL2TEST results in
the object being created and displayed with the content aspect.
BUG: CL2TEST Not Properly Activating Links to Embedded Objects
Double-clicking a link to an embedded object in CL2TEST results in the
activation remaining on CL2TEST. The correct action would be for the
container of the embedded object to obtain the activation and edit the
object visually (if possible).
BUG: IOleObject::Close(OLECLOSE_NOSAVE) and DoVerb()
An OLE 2.0 container application inserts a new embedded object into a
document. The container calls IOleObject::Update() on the object to update
the cache, then calls IOleObject::Close(OLECLOSE_NOSAVE) to transition the
object back to the running state. Finally, the container tries to rerun the
object by calling IOleObject::DoVerb().
In this particular scenario, DoVerb() will return STG_E_FILENOTFOUND, and
the object will not be rerun.
BUG: OLE 1.0 Server Launched for Paste Link
An OLE 1.0 server application copies an object to the clipboard, then
enters the blocked state. An OLE 2.0 container application then attempts to
paste a link to the object from the clipboard. The OLE 2.0 application is
frozen.
Next, the OLE 1.0 application is shut down. This unfreezes the OLE 2.0
container application, which proceeds to paste the link to the OLE 1.0
object. However, an instance of the OLE 1.0 server is launched. Normally,
the server is not run in a paste-link scenario.
BUG: OLE 2.0 Compatibility Layer Uses Document IDataObject
Whenever the OLE 1.0 client compatibility layer uses IDataObject, it uses
the OLE 2.0 server's document-level data object rather than the server's
pseudo-object data object.
BUG: CreateFromTemplate of OLE 2 Object into OLE 1 Container
An OLE 2.01 object is inserted into an OLE 1.0 container using
OleCreateFromTemplate(). The OLE libraries start the server, but then the
object creation fails, or a blank object is created.
BUG: IROT::Register() and IOL::SetDisplayName() Inconsistency
IRunningObjectTable::Register() allows monikers that are not valid
filenames to be registered as file monikers. However, if the display name
string passed to IOleLink::SetSourceDisplayName() is not a valid filename,
SetSourceDisplayName() returns STG_E_FILENOTFOUND.
BUG: OLE Type Emulation for Previously Loaded Objects
OLE type emulation is the process that allows the application user to
specify that all objects of some particular type are henceforth to be
activated as objects of some alternate, emulating type. When objects of the
original type are subsequently run, the server for the emulating type is
launched to serve them.
However, this emulation does not occur for objects of the original type
that were already in the loaded state when the type emulation occurred.
When such objects are subsequently run, they are run as the original type,
not the emulating type. The original server is launched, not the server for
the emulating type.
BUG: Relative Monikers and OLE 1.0 Link Objects
When a link object from an OLE 2.0 application is copied to the clipboard
and then pasted into an OLE 1.0 application, the OLE 2.0 emulation layer
preserves the object's relative moniker. If the OLE 1.0 application
document is closed and then reopened by an OLE 2.0 version of the
application, OLE 2.0 will create a full moniker for the linked object by
appending the preserved relative moniker to the file moniker for the
document. This full moniker will be incorrect, because it will point to the
new document rather than to the first OLE 2.0 application's document that
contains the original linked object.
However, OLE 2.0 will still be able to bind to the linked object by
following the absolute moniker that is also stored with the object
(providing that the absolute location of the original linked object has not
changed). At the time of this binding, OLE will then correct the full
moniker for the object.
BUG: OleConvertStorageToOLESTREAM() Fails When CLSID Is NULL
The OleConvertStorageToOLESTREAM() API (application programming interface)
call is used to convert the storage of an embedded object from the OLE 2.0
storage model to the OLE 1.0 storage model. However, if the OLE 2.0 object
has a CLSID of NULL, then OleConvertStorageToOLESTREAM() fails with a
return code of OLE_E_CLASS.
BUG: Paste-Linking a 256-Color Paintbrush Object
A 256-color bitmap is loaded into Microsoft Paintbrush version 3.11. The
image is selected and then copied to the clipboard. An OLE 2.0 application
then pastes a link to the object from the clipboard. To perform the paste-
link operation, the container calls OleCreateLinkFromData(), specifying
OLERENDER_FORMAT as the rendering option and CF_DIB as the desired format.
The resulting link object in the OLE 2.0 application has an incorrect
appearance, such as being colored solid black.
PRB: IOleObject::IsUpToDate() and OLE 1.0 Link Objects
An OLE 2.0 container application calls IOleObject::IsUpToDate to determine
whether or not an OLE 1.0 link object is up to date. IsUpToDate() returns
S_FALSE, even though the object is actually up to date.
BUG: IOleCache::Cache(), ADVF_DATAONSTOP, and OLE 1.0 Objects
An OLE 2.0 container application document contains an embedded OLE 1.0
object. The container calls IOleCache::Cache() to control the cached
presentation data for the object, and specifies ADVF_DATAONSTOP as the
advise flag to Cache(). The user makes some changes to the object in the
OLE 1.0 server, then attempts to update the object's presentation in the
server by choosing the Update command from the File menu. Finally, the user
closes the object server.
In this specific scenario, the object's presentation in the server is not
updated. The object's native data, however, is correct.
BUG:IOleObject::IsUpToDate Returns Wrong Value for Manual Link
To determine whether an OLE link needs to be updated, an OLE 2.0 container
application needs to call IOleObject::IsUpToDate. If this method returns
S_FALSE, the link needs to be updated; otherwise, the link can be
considered up to date. However, calling IOleObject::IsUpToDate on a manual
link while the link server is not running results in an a return value of
S_FALSE, even if the link is current. The result of this is that OLE 2.0
container applications may update links unnecessarily.
BUG: Borland WINSIGHT Causes GP Faults w/Some OLE Sample Apps
If Borland's WINSIGHT tool is running when you start some of the sample
applications that have been included in the OLE 2.01 SDK, a general
protection (GP) Fault will occur before the main application window
appears.
The following OLE 2.01 SDK sample applications are affected:
cl2test.exe
sr2test.exe
outline.exe
cntroutl.exe
svroutl.exe
icntrotl.exe
isvrotl.exe
BUG: Windows OLE DLLs Do Not Convert Mac OLESTREAM
The OLE 2.01 libraries will not convert a Mac OLESTREAM to a Windows
OLESTREAM. Similarly, the Windows OLE dynamic-link libraries (DLLs) will
not convert a Mac IStorage to a Windows OLESTREAM.
BUG: Printing Does Not Work from CL2TEST.EXE
Printing does not work correctly from CL2TEST.EXE. Choosing Print from the
File menu results in a blank printout.
