This is my point, it's best to find a way to offer a cross-platform
interface for this if possible. I've no experience using WM_COPYDATA so
can't really comment much here.

Did you ever test with the PassWin32MessagesToLCL define:

WM_COPYDATA is not a User message I think. WM_COPYDATA is part of an IPC
mechanism, which needs a general implementation in the LCL, with
specifics in win32, gtk, qt etc..


Right, WM_COPYDATA is not a user message - I never assumed that. But 
it's a Message widley used in Windows, so Lazarus has to support it for 
many cases.
I, for example, needed it to talk to some external application 
remote-controlled by WM_COPYDATA - that's why I tracked down the way of 
the message and submitted this patch.


I'm not quite shure if we need it in other interfaces too - it's a 
windows-specific message.

Did you ever test with the PassWin32MessagesToLCL define:
http://wiki.lazarus.freepascal.org/LCL_Defines#Win32_defines

?

In recent subversion Lazarus user messages are activated by default
(the define I mentioned above no longer exists), could you test if
this solves your problem without the patch?



Already done that - it has no influence on WM_COPYDATA.

[lazarus] Patch for processing WM_COPYDATA in Win32 / BugID 9210

2008-01-16 Thread Lukas Gradl 
Some time ago I reported a problem with sending WM_COPYDATA-Messages 
under windows:

http://bugs.freepascal.org/view.php?id=9210

As far as I could find the function WindowProc in win32callback.inc eats 
up the message so it never reaches the MessageHandler defined in the app.


So I changed LCL\interfaces\win32\win32callback.inc

This is the diff-File:


Index: win32callback.inc
===
--- win32callback.inc   (revision 13779)
+++ win32callback.inc   (working copy)
@@ -1141,6 +1141,13 @@
   Assert(False, Format('Trace:WindowProc - Window Value: $%S-%d; Msg 
Value: %S; WParam: $%S; LParam: $%S', [IntToHex(Window, 4), Window, 
WM_To_String(Msg), IntToHex(WParam, sizeof(WParam)*4), IntToHex(LParam, 
sizeof(LParam)*4)]));


   case Msg of
+   WM_COPYDATA: // passthrough of WM_COPYDATA-Messages
+   begin
+  LMessage.Msg := Msg;
+  LMessage.WParam := WParam;
+  LMessage.LParam := LParam;
+  WinProcess := false;
+   end;
 WM_ACTIVATE:
 begin
   case LOWORD(WParam) Of
