Some comments on how the Obj subsystem for handling OLE objects
|
|
is herein implemented.
|
|
|
|
Written (2.14.92) by v-dougk (Doug Kent)
|
|
|
|
Metafile and bitmaps have always been described in the Write
|
|
file format (and in memory) by a PICINFOX structure. For OLE
|
|
objects the PICINFOX structure is replaced by the OBJPICINFO
|
|
structure of the same size.
|
|
|
|
OBJPICINFO has a field (lpObjInfo) which is a pointer to another
|
|
structure (OBJINFO) which is globally allocated. This structure contains
|
|
info about the object which doesn't need to be stored in the file
|
|
with the object data.
|
|
|
|
The object data as obtained from OleSaveToStream() is stored in the
|
|
Write file format immediately following the OBJPICINFO structure.
|
|
Object data is not actually written to the file until the user
|
|
does a File.Save. For a newly-created object, the OBJPICINFO structure
|
|
is the only data saved until that point. If the object is an
|
|
unfinished one from an Insert.Object operation, then not even the
|
|
OBJPICINFO structure is saved. In that case the object is solely
|
|
represented by the OBJINFO structure until an OLE_CHANGED or OLE_SAVED
|
|
is received. Then an OBJPICINFO structure is saved to the file.
|
|
|
|
The OBJINFO structures are allocated for all objects when the file
|
|
is opened. This involves writing new OBJPICINFO data to the doc
|
|
(with the new lpObjInfo values) on open. This makes the doc dirty,
|
|
but we reset the doc dirty flag to make it undirty.
|
|
|
|
The lpObjInfo pointers are passed to the OLE create functions for the
|
|
lpClient value. This is a crucial aspect of the implementation as
|
|
the CallBack function passes back this pointer, allowing us to identify
|
|
the object, and query and set its state without having to access
|
|
the file on disk. As I was not aware of the importance (or existence)
|
|
of this feature until late, it was patched in. It is not perfectly
|
|
implemented and could use some polishing.
|
|
|
|
As much as I tried to seamlessly integrate objects into the existing
|
|
Write architecture, there have been glitches:
|
|
|
|
1) Writing into the doc as the visible page is being drawn
|
|
(See ObjLoadObjectInDoc() in DisplayGraphics() in picture.c)
|
|
tends to mess things up. The drawing code (namely
|
|
UpdateWw(), expects certain state variables (like the
|
|
pedls and the pwwds) to be constant during a single call
|
|
to UpdateWw(). Writing into the doc alters those variables.
|
|
Workaround uses vfInvalid in ObjSetPicInfo().
|
|
2) Write does not expect data to be entered other than in data
|
|
currently being displayed on the screen, whereas we
|
|
frequently operate on objects all over the doc (ObjEnumInDoc()).
|
|
Workaround is to use ObjCachePara() instead of CachePara().
|
|
3) Asynchronicity wreaks havoc on Write. Since every action
|
|
in Write is affected by the current state, if an action
|
|
occurs out of normal sequence, i.e., occurs in an improper
|
|
state, then blamo big trouble. When events happen
|
|
recursively state variables cannot be restored without a
|
|
state 'Pushing and Popping' mechanism.
|
|
|
|
This is especially true for 'cp' variables. cp's are pointers
|
|
into the document and global cp state variables are ubiguitous.
|
|
Global cp variables include the selection and undo variables
|
|
mentioned above, plus many others. See ObjPopParms() and
|
|
ObjPushParms().
|
|
|
|
While waiting for an object to release (see WMsgLoop()) we
|
|
stub out WM_PAINT message responses using the nBlocking variable.
|
|
Between document opening and closing we set the doc fDisplayable
|
|
flag to FALSE. NOTE: we ought to do something like this in
|
|
IDPromptBoxSz() -- many of the asynchronicity problems occur
|
|
when calling MessageBox() (which yields).
|
|
|
|
Hopefully OLE 2.0 will implement an OleBlockClient() mechanism.
|
|
|
|
|
|
Notes on Asynchronicity: Ole calls that require communication with the
|
|
server may be asynchronous. The following rules apply:
|
|
|
|
1) Only one asynchronous call at a time may be made for a given object.
|
|
2) The OleCreate* calls must complete before some synchronous
|
|
calls such as OleGetData().
|
|
3) All asynchronous activity must be complete before calling
|
|
OleRevokeClientDoc.
|
|
|
|
Asynchronous calls return OLE_WAIT_FOR_RELEASE. You don't know
|
|
that an asynchronous call has completed until the CallBack function
|
|
receives an OLE_RELEASE message for that object. If you ignore this
|
|
and issue an offending call for the object, the call will
|
|
return OLE_BUSY.
|
|
|
|
We deal with these rules by calling OleQueryReleaseStatus to
|
|
determine whether an object is busy before making any Ole call
|
|
(see ObjWaitForObject()). If the object is busy then we spin until the
|
|
object is not busy. After 6 seconds we put up a msg box which, depending
|
|
on the flags we set, may allow the user to stop waiting and cancel the
|
|
operation (see notes in fnObjWait()).
|
|
|
|
Note that the OleCreate calls can fail in 3 different ways that aren't
|
|
documented (not at this point anyway).
|
|
|
|
1) The call returns error immediately. In this case you mustn't depend
|
|
on the returned lpObject to be NULL. If it is not NULL, ignore
|
|
it -- it needn't be deleted.
|
|
|
|
2) The call returns OLE_WAIT_FOR_RELEASE and eventually you get an
|
|
OLE_RELEASE and OleQueryReleaseError() is != OLE_OK. In
|
|
this case you gotta delete the lpObject that was returned by
|
|
the original call.
|
|
|
|
3) The call completes, but you receive OLE_CLOSED on the object
|
|
without receiving OLE_CHANGED. This indicates that for some
|
|
reason the native data could not be obtained from the server.
|
|
The object must be deleted in this case. Write currently
|
|
handles this properly for Insert.Object (OleCreate), but not
|
|
for other cases (OleCreateFromFile,...).
|
|
|
|
The Links dialog should be optimized so that it doesn't require that all
|
|
links be loaded at once. The Printing process could use the same
|
|
optimization.
|
|
|
|
Cutting, copying and pasting works as follows. Any object that exists
|
|
in docScrap (where clipboard contents are stored) must be a unique
|
|
object. Thus when we copy we clone any objects in the selection.
|
|
When we cut we needn't clone since the objects have been deleted
|
|
from the document. When we paste we clone.
|
|
|
|
Deleted objects and cut objects that get purged from docScrap (and
|
|
therefore become effectively deleted), are not actually deleted right
|
|
away. These objects get shovelled into docUndo for access by the
|
|
Undo function. Even when the objects get purged from docUndo
|
|
(by another undoable operation), they are still not deleted. These
|
|
objects never finally get deleted until ObjCollectGarbage() is
|
|
called. This function is called on a timer about every 5 minutes.
|
|
It enumerates all documents and deletes any objects not found.
|
|
|
|
The reason for not deleting objects right away is that it would've
|
|
hurt performance to check the contents of docUndo and docScrap
|
|
every time they change. It also would've been a nasty programming job
|
|
since those change points are not localized physically or logically.
