Hi!
I am currently running Lazarus 0.9.29 with FPC 2.5.1 from February
4th, and obviously the IDispatch implementations are still not
working.
Anyone know when, or if, this is being worked on?
Any timeplan?
I am aware that this is a Win-only feature, but it's still a pretty
important piece of Win development.

Regards,
/Jörgen

I totaly agree with you. Waiting for it since few years now... but
waiting patiently :-)

Most of COM is donation driven. IOW patches are committed, there is
not sb continuously working on it.

There is one contributor but he comes and goes, sometimes with 18
months hiatus.

What does not work with IDispatch for you? Paticular bug reports or
small tests would be fine. I usually look at fpc com issues to fix
them.

Well, it's been a couple of months since my last test, but trying to
create a Shell ToolTip handler in Windows (especially 64-bit) returns
Nil on most interfaces.
I have tried code that's working fine in Delphi, but as we all know,
that doesn't work on 64-bit systems.
I'll be back later with example code.

I have had some success with msword, using idispatch but
OleVariant(servername).methodname for calling methods

Hi,

I am trying to use a dll I use in Delphi with a TLB. I currently use
fpc rev 15435 (today), I think I found a small bug (-> SIGSEGV) in
http://svn.freepascal.org/svn/fpc/trunk/packages/winunits-
base/src/comobj.pp line 1289 (1283 to 1289) :

         Code: [Select]res:=DispatchInterface.GetIDsOfNames(GUID_NULL,
NamesArray,NameCount,
{$ifdef wince}
                     LOCALE_SYSTEM_DEFAULT
{$else wince}
         GetThreadLocale
{$endif wince}
         ,IDs); 
you get two " , ", one after NameCount and one before "ID"

Should I post a bug report?

Edit :sorry, this is not related, the syntax is good

I am not sure, but this seems to be a similar problem I had in the
past i will test again in the following days...
