This is the status for DDE (i.e. raw dde messages) and ddeml.
|
|
|
|
DDE was implemented by Micheal Veksler some time ago, it has been reported as broken
|
|
by changes in the server and related parts of wine. AFAIK no-one has tried to fix these
|
|
and I have not tried to test them.
|
|
|
|
ddeml was untouched until December 1998 when some of the Corel/Macadamian team started
|
|
writing bits that were needed by Corel for the WordPerfect Suite port. These were mainly
|
|
around string handling and have been identified in the change history for each routine.
|
|
They were written to cope with a single instance only. About a week later I started
|
|
looking at ddeml as a whole.
|
|
|
|
The initialisation was tackled first, then the routines produced by Corel/Macadamian
|
|
were modified to cope with multiple instances of dde client/server and a first cut at
|
|
the un-initialise routine.
|
|
|
|
DdeNameService has now been produced as a first-cut routine, but the monitor notification
|
|
must be tackled, followed by the main message reception routine and the invoking of the
|
|
callback. Serious testing from this point may well depend on Wine thread handling
|
|
settling down.
|
|
|
|
The strategy so far has been to tackle the Unicode versions first. Once they have been
|
|
accepted as close to complete then the 32-bit ASCII routines then the 16-bit routines.
|
|
|
|
It is recognised that the solutions adopted may well not be suitable for wine-OS2, since
|
|
that OS has its own DDE rotuines intermediate in integration between raw DDE and ddeml,
|
|
also O/S 2 users may well want programs running under Wine to talk to native O/S 2 programs.
|
|
I do not have knowledge of MacOS or the internals of BeOS, but these may suffer from the
|
|
same problems.
|
|
|
|
TO DO
|
|
|
|
Complete initialisation, some of the 2nd call validation conditions have not been worked out
|
|
yet and the code for enabling the message loop needs writing.
|
|
|
|
Complete initialize and unitialize, also add the callback handling to DdeNameService.
|
|
|
|
Add true Unicode handling to CreateStringHandle, QueryString, CmpStringHandles. Also find
|
|
out why Initialize needs ASCII and Unicode variants.
|
|
|
|
Add DdeGetLAstError and related handling in all other modules. Also find out what to do about
|
|
storing errors that result in the instance failing to initialise in some way.
|
|
|
|
|
|
Just about all the rest
|
|
|
|
More specific items are commented in the code.
