Subject: DCOM question
Hi all!
I'm a very newbie at this list and in Delhpi an in DCOM.
I have no problem creating a simple COM example. A iwant to use a
very simple function:
function TClass2.Exam1(s. WideString): HResult;
begin
Exam1:=123;
end;
It works local as in-process-server (DLL) and as well as out-process-server.
[A simple question here: I assume I always have to use a ]
[out-process-server if I want to apply the DCOM technique.(?)]
But I'm totally unable to call it from a remote client via a
real network.
I simply use:
SomeInterfaceVariable := CoTClass2.CreateRemote(<someIP>);
The client hangs. I assume the reason is: The server tries
tho create a window (TForm1) at the server side. And I can
imagine the client is not allowed to pop up some windows at the
server side.
But how to avoid the TForm1? If I try
File|New|... | COM-Server
a window pops up: "first create an running project", followd by
some instructions how to create an in-process server. But an
in-process server (DLL) seems not to work in DCOM.
If I start:
File|New|Application
Delphi always creates the TForm1. This seems to be the reason
for the crash at server side (see above).
If I try:
File|New|...| Console Application
and then:
File|New|...|COM Server
I can compile the server. But it crashes immediately after
launching the server.
Any suggestions? Or can anybody point me to a simple tested
DCOM (not COM) example ?
Thank you in advance
