win32:
|
|
need to support window stations
|
|
login screen on NT is a separate window station
|
|
handle display changes

|
not handling international characters
|
|
|
|
---
|
|
don't allow leaving screen when any key is down
|
|
that includes shift keys and mouse buttons
|
|
caps lock, etc must not be down but can be on
|
|
|
|
not distinguishing between caps lock and shift lock
|
|
In Caps Lock mode, the alphabetic keys send their uppercase (shifted) char-
|
|
acter when pressed alone. For Caps Lock mode, pressing and releasing the
|
|
lock key turns on the mode and pressing and releasing the lock key again
|
|
turns off the mode. In Shift Lock mode, all keys on the main keypad send
|
|
their shifted character when pressed alone. For Shift Lock mode, pressing
|
|
and releasing the Lock key turns on the mode, and pressing and releasing
|
|
either the Lock or the Shift key turns off the mode.

problems with CLIPBOARD and KDE and NEdit
|
|
KDE mail reader (others?) and NEdit never reply to selection request
|
|
perhaps a general Motif problem?
|
|
|
|
currently sending all clipboards to all clients
|
|
some clients may not need all clipboards
|
|
add filtering mechanism
|
|
|
|
must find app that correctly sets the CLIPBOARD selection for testing
|
|
synergy must note changes to one or both selections
|
|
seems to be having trouble with noting CLIPBOARD after PRIMARY changes
|
|
|
|
investigate klipper
|
|
KDE's clipboard manager?
|
|
it crashed once when server did (see below)
|
|
|
|
---
|
|
got crash when opening netscape window after trying copy in KDE mail
|
|
BadWindow in ChangeWindowAttributes
|
|
also got it when trying to transfer big clipboard from secondary
|
|
or just after transferring and perhaps trying to set locally
|
|
|
|
---
|
|
sometimes not sending correct clipboard
|
|
some kind of race condition i think
|
|
can select text then switch and get empty clipboard
|
|
switching back to owner screen then out gets correct clipboard
|
|
|

|
|
screen resize should report new mouse position
|
|
client could change it to keep mouse on screen
|
|
server will need to know new position
|
|
may need to ignore mouse events sent after resize but before server
|
|
knows about the change.
|
|
not handling screen resizing yet
|
|
|
|
---
|
|
not handling screen saver at all yet
|
|
|
|
---
|
|
slow leaving primary screen on X
|
|
possibly due to getting primary clipboards
|
|
possibly something else
|
|
could try asynchronously getting primary clipboard
|
|
race condition on secondary wrt pasting
|

|
|
win32 hook DLL sometimes not unloaded when server is killed?
|
|
will get assertion on restart as if DLL was still loaded.
|
|
can tell because all DLL copies share data segment.
|
|
should prevent multiple copies from loading (or initializing)
|
|
replace asserts with (multithread locked) check of variables
|
|
return 0 if busy
|
|
server must handle failure
|
|
try to figure out why it's not unloading

num-lock light on isabel doesn't respond to generated events.
|
|
seems to be linked to something lower-level. however, keytest
|
|
does report num-lock keyboard state is being toggled.
|
|
|
|
other toggle lights don't always respond immediately
|
|
usually go on/off when active window changes though
|
|
|
|
---
|
|
avoid fullscreen transparent window
|
|
using CBT hook to discard activation/focus messages
|
|
but it's not being called when we lose keyboard input
|
|
also, we sometimes don't get the keyboard input to start with
|
|

|
|
keyboard hook problems
|
|
now passing keyboard events through in most cases
|
|
this fixes problem on isabel where toggle lights don't toggle
|
|
and num-lock behaved incorrectly (generated wrong keys).
|
|
seems the DefWindowProc() needed to process the keys
|
|
unfortunately, keys sometimes leak into wrong app. seems related
|
|
to times when we don't get the keyboard input. key events are
|
|
not delivered to app on primary until cursor returns to primary.
|
|
no idea how that's possible.
|
|
current have some code to check active window and reset it in
|
|
keyboard hook. that code doesn't work.
|
|
seem to be having problems with windows key now, too. looks like
|
|
a down is sent but not the corresponding up so secondary system
|
|
thinks the key is always down.
|

server asserts if two clients with same name try to connect
|
|
should simply refuse second client
|
|
also not reaping disconnects very fast
|
|
investigate slowness
|
|
|
|
---
|
|
blown assert:
|
|
client crashed and primary jumped to primary
|
|
left over queued motion events then processed
|
|
caused call to CServer::onMouseMoveSecondary
|
|
m_protocol is NULL because we're on primary screen
|
|
must flush queued events when jumping to primary
|
|
check for other things to do when jumping to primary
|

not detecting disconnect when remote side crashes
|
|
is there some socket flag to help with this?

should catch signal when closing console window and close nicely
|

|
|
sending same clipboard repeatedly from win32 server
|
|
can we detect no change?
|

|
|
key events sent to console on win me (95/98?) are very slow
|
|
1/4 to 1/2 second delay before key up is processed
|
|
key up log message is also delayed
|
|
console causing a system-wide delay?
|
|
|
|

|
|
adjust thread priorities on win32
|
|
maybe remove changes altogether
|
|
currently isabel starts single-stepping mouse when dragging window
|
|
sometimes it goes normal speed but it's mostly very slow
|
|
even a very high priority doesn't seem to help
|
|
haven't tried real-time priority
|
|
a very high priority on client fixes delay when typeing into console
|
|
is it the output console causing the slowness?

disable ctrl+alt+del info:
|
|
SystemParametersInfo(SPI_SETSCREENSAVERRUNNING, TRUE, &dummy, 0)
|
|
fools system into thinking screen saver is running
|
|
that disables ctrl+alt+del, alt+tab, ctrl+esc
|
|
dunno if keystrokes are queued
|
|
may be limited to win 95/98/me
|
|
win nt sp 3 and above:
|
|
low-level keyboard hook is called before ctrl+esc, alt+tab, alt+esc
|
|
use that to capture and disable
|
|
seems that low-level hook is notified of ctrl+alt+del but can't stop it
|
|
win nt sp 2 and below
|
|
ctrl+esc can be disabled by replacing task manager (dunno how)
|
|
RegisterHotKey() can be used to catch alt+tab and alt+esc
|
|
only while app is running, of course
|
|
win nt
|
|
keyboard filter driver can capture keys (see win NT DDK)

some info on changing keyboard scan code mapping

can be used to disable keys but looks like reboot is required

Q179905
|

suggestion for bypassing hook code when called by debugger.
|
|
may prevent system from getting locked up when debugging.
