Summary: Something wrong with WH_GETMESSAGE hook (TeamViewer)
Product: Wine
Version: 1.1.33
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: user32
AssignedTo: wine-bugs at winehq.org

TeamViewer 3 with OS=NT4.0 to workaround bug 12067
All seems to work (except for the unrelated bug 11727) but the chat the other
windows seems to loop (when a connection is active) when many input messages
are sent on this windows (for example when you press 2 or more keys on the
chat). Obviously in windows there aren't problems.
To workaround this in then dlls/user32/message.c
...
break;
case MSG_HARDWARE:
if (size >= sizeof(msg_data->hardware))
{
...
HOOK_CallHooks( WH_GETMESSAGE, HC_ACTION, flags & PM_REMOVE, (LPARAM)msg,
TRUE );
return TRUE;
}
...
I add this check (or you can remove the whole call...)
...
if (flags & PM_REMOVE) <-
HOOK_CallHooks( WH_GETMESSAGE, HC_ACTION, flags & PM_REMOVE, (LPARAM)msg, TRUE
...
and now there aren't problems and it works very well.
I know the patch isn't right, since the WH_GETMESSAGE should return also the
not removed peeked messages but I think there is something wrong with the
hooking system!
Note:
To understand what Teamviewer do I have followed the source code VNCHooks.dll
'cause it's very similar (also with the name and meanings of the registerd
messages).
