This is a more hackish but more compatible solution to the problem of
data sent using wxIPC_UTF8TEXT format being simply lost when using DDE
for IPC classes. We must use CF_TEXT for the DDE to pass our data, but
we can try to decode it as UTF-8 in the client and assume it was sent in
this format if it worked. This obviously suffers from false positives as
any ASCII string will still be assumed to be UTF-8, but there shouldn't
be any real harm coming from this.
This change also makes sending data in wxIPC_UTF{16,32}TEXT formats work
as well by converting it to UTF-8.
Update the sample to call Advise() with both wxIPC_UTF{8,16}TEXT formats
and remove the now unnecessary wxDDEConnection::m_dataType member.
Closes#17900.
This reverts commit c657fd3d61 because
changing the format of DDE advise requests/replies is not a good idea:
other applications (those using previous versions of wxWidgets or even
not using wxWidgets at all) may rely on getting data in real CF_TEXT
format rather than in one of text formats preceded by the extra byte
containing the actual format and the previous commit would have silently
broken this.
Another fix for #17900 will be implemented instead.
wxIPC API doesn't map well onto DDE, as we don't have wxIPCFormat
parameter in StartAdvise() but do allow specifying the format when
calling Advise() itself, whereas DDE requires specifying the format when
establishing the advise loop and the data always must use this format
later.
Because of this, we have to pass the actual format with the data itself
instead of relying on DDE formats support. This has the advantage of
allowing wxIPC_UTF8TEXT to work, while previously it didn't and
couldn't, as DDE only supports the standard (or custom, but registered)
clipboard formats and it wasn't one of them. Of course, this also has a
disadvantage of having to make another copy of the data, but this seems
unavoidable.
This change allow Advise() overload taking wxString to work, including
for non-ASCII strings, as shown by the update to the IPC sample. It also
makes wxDDEConnection::m_dataType unnecessary, as we must always use the
format passed to DDE callback anyhow when handling XTYP_ADVREQ.
Closes#17900.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.
