+ Deleting contacts from protocols that store the contact list on the server:
+ If a contact is deleted while the protocol is online, it is expected that the
+ protocol will have hooked me_db_contact_deleted and take the appropriate
+ action by itself.
+ If a contact is deleted while the protocol is offline, the contact list will
+ display a message to the user about the problem, and set the byte setting
+ "CList"/"Delete" to 1. Each time such a protocol changes status from offline
+ or connecting to online the contact list will check for contacts with this
+ flag set and delete them at that time. Your hook for me_db_contact_deleted
+ will pick this up and everything will be good.

+ Returns 0 on success, -1 if Handle is invalid
+ If one of the hooks returned nonzero to indicate abort, returns that abort
+ value immediately, without calling the rest of the hooks in the chain
+ Notes on calling TNotifyEventHooks() from a thread other than that which owns
+ the main Miranda window:
+ It works. The call is routed to the main thread and all hook subcribers are
+ called in the context of the main thread. The thread which called
+ TNotifyHookEvents() is paused until all the processing is complete at which
+ point it returns with the correct return value.
+ This procedure requires more than one wait object so naturally there are
+ possibilities for deadlocks, but not many.
+ Calling TNotifyEventHooks() from other than the main thread will be
+ considerably slower than from the main thread, but will consume only slightly
+ more actual CPU time, the rest will mostly be spent waiting for the main thread
+ to return to the message loop so it can be interrupted neatly.

+ referring to the hook otherwise. Note that debug builds will warn with a
+ MessageBoxA if a hook is attempted on an unknown event. All hooks will be
+ automatically destroyed when their parent event is destroyed or the programme
+ ends, but can be unhooked earlier using TUnhookEvent(). MIRANDAHOOK is defined as
+ function(wParam: WPARAM; lParam: LPARAM): int; cdecl;
+ where you can substitute your own name for function. wParam and lParam are
+ defined by the creator of the event when TNotifyEventHooks() is called.
+ The return value is 0 to continue processing the other hooks, or nonzero
+ to stop immediately. This abort value is returned to the caller of
+ TNotifyEventHooks() and should not be -1 since that is a special return code
+ for TNotifyEventHooks() (see above)

+ sent to a window, rather than a function being called.
+ Note that SendMessage() is a decidedly slow function so please limit use of
+ this function to events that are not called frequently, or to hooks that are
+ only installed briefly
+ The window procedure is called with the message 'message' and the wParam and
+ lParam given to TNotifyEventHooks(). The return value of SendMessage() is used
+ in the same way as the return value in HookEvent().
+ *)

+ (* TUnhookEvent
+ Removes a hook from its event chain. It will no longer receive any events.

+ *)
+ TUnhookEvent = function(Handle: THandle): int; cdecl;

+ on exit, but can be removed from the list earlier using
+ TDestroyServiceFunction()
+ Returns NIL if name has already been used. MIRANDASERVICE is defined by the
+ caller as
+ function(wParam: WPARAM; lParam: LPARAM): int; cdecl;
+ where the creator publishes the meanings of wParam, lParam and the return value
+ Service functions must not return CALLSERVICE_NOTFOUND since that would confuse

+Opening
+--------
+
+Chess4Net is a program for playing chess via Internet. It can be used as standalone application (Socket version for Microsoft Windows or Linux) or as plug-in for such instant messengers as Skype, Miranda, QIP Infium, Trillian Pro and &RQ. Two modes of chess game are supported: standart chess and its random counterpart - PP Random Chess. Chess4Net supports sudden death and incremental time controls as well as possibility to give your opponent a time-handicap. If you want to improve your chess skills there is also a support for a training mode. You can also invite other contacts to watch the games you're playing in real-time.
+
+Middle game
+------------
+
+Installation:
+
+Socket version:
+ Extract the archive to desired folder on your computer.
+
+Skype plug-in:
+ There're two options. You can either install from installation package or download an archive and extract it to a desired folder on your computer.
+
+Miranda plug-in:
+ Extract archive to the Miranda Plugins directory and re/start Miranda.
+
+QIP Infium plug-in:
+ Extract archive to the QIP Infium Plugins directory and re/start QIP Infium
+
+Trillian Pro plug-in:
+ Extract archive to the Trillian plugins directory; go to Trillian->Trillian Preferences... choose Plugins and check Chess4Net_trillian.dll box.
+
+&RQ plug-in:
+ Extract archive folder Plugins\ to the installation directory of &RQ (the one where &RQ.exe is located).
+
+How to use:
+
+Socket version:
+ 1) Start Chess4Net.exe
+ 2) Choose 'Connect...'
+ 3) Type in-your name into 'Your Nick' edit-box.
+ a) Choose Server; provide your partner with IP (type 'ipconfig' in Start->Run... or command line to find it out in Windows; run ./get_ip.pl from installation in terminal on Linux); enter Port# (agree upon it with your partner).
+ b) Choose Client; Enter IP or domain Name that your partner told you; Enter Port# (for each instance of Chess4Net it should be unique).
+ 4) Click OK and wait until the connection is completed.
+
+Skype:
+ 1) Run Chess4Net_Skype.exe. If you don't have Skype running it will start automatically. Click 'Allow access' when dialog 'Chess4Net_Skype.exe wants to use Skype' pops-up.
+ 2) When a window with Skype contacts appears choose a contact you want to play chess with.
+ 3) Wait until connection is completed.
+
+Miranda:
+ 1) Right-click the contact you want to play chess with and select 'Chess4Net' from contact pop-up menu.
+ 2) Wait until connection is completed.
+
+QIP Infium:
+ 1) Open a chat window for the contact you want to play chess with.
+ 2) Press 'Chess4Net' message button (below the upper frame on the right where the incomming and outgoing messages are shown).
+
+Trillian Pro:
+ 1) Right-click the contact you want to play chess with and select 'Chess4Net' from pop-up menu or open message window for that contact and type "/CHESS4NET" without double quotes.
+ 2) Wait until connection is completed.
+ NB: Chess4Net uses instant messages to transmit moves and other information. In Trillian Pro there is no way to suppress messages unlike in Miranda, so
+you may want to switch off the sounds for incomming messages while playing.
+
+&RQ:
+ 1) Open a chat window for the contact you want to play chess with.
+ 2) Press 'Chess4Net' chat button (below the upper frame where the incomming and outgoing messages are shown).
+ 3) Wait until connection is completed.
+
+Chess4Net uses context-menu so if you find yourself in trouble don't hesitate and press the right button of your mouse.
+After several runs in installation folder (socket, Skype) or \Chess4Net folder (messengers other than Skype) you will find Chess4Net_GAMELOG.txt with all games you have played with Chess4Net so far, user data base (Chess4Net.pos and Chess4Net.mov) and external data bases (other files *.pos and *.mov) which are used in training mode.
+
+Training mode:
+
+The training mode can be switched on/off in Game Options menu. The user data base and external data bases are used in training mode only. The User DB will contain all games played by the user in the training mode, and data from it is used to provide prioritized move hints.
+User DB can learn from your games in order to give you best choices. You can also select an external DB to use together with user DB to improve the quality of move hints.
+
+Game transmitting mode:
+
+While you're playing some games you can invite other contacts to gollow up these games in real-time. Therefore you must
+start a new session of Chess4Net for a contact you want the game(s) be transmitted to. A mode selection dialog appears
+asking if game broadcasting has to be started. You must select 'Yes' (if you select 'No' an ordinary game session is created). After that you should select a game for transmition (only if there're several games in progress). After your contact
+connects he/she'll be able to watch the game.
+
+
+Endgame
+--------
+
+Chess4Net is constantly improving and it is up to you what features will be included in the next release. Please send all your wishes and/or complaints to E-mail: packpaul@mail.ru or ICQ: 98750806 or Skype: packpaul1
+Chess4Net is a software and, like it is peculiar to software, it will never be bug free. Please report all bugs you may find to packpaul@mail.ru but see change log before reporting.

+ New bug fixes (Peter Haas).
+
+ Version 1.422
+ 2002-05-14 - Fixed some critical leaks, thanks to Peter Haas tips.
+ New translation for German (Peter Haas).
+
+ Version 1.421
+ 2002-05-06 - Now uses new ZLIB version, 1.1.4 with some security
+ fixes.
+ LoadFromResourceID and LoadFromResourceName added and
+ help file updated for that.
+ The resources strings are now located in pnglang.pas.
+ New translation for Brazilian Portuguese.
+ Bugs fixed.
+
+ IMPORTANT: As always I´m looking for bugs on the library. If
+ anyone has found one, please send me an email and
+ I will fix asap. Thanks for all the help and ideas
+ I'm receiving so far.}

+
+{
+ Windows NT provides support for native Unicode windows. To add Unicode support to a
+ TWinControl descendant, override CreateWindowHandle() and call CreateUnicodeHandle().
+
+ One major reason this works is because the VCL only uses the ANSI version of
+ SendMessage() -- SendMessageA(). If you call SendMessageA() on a UNICODE
+ window, Windows deals with the ANSI/UNICODE conversion automatically. So
+ for example, if the VCL sends WM_SETTEXT to a window using SendMessageA,
+ Windows actually *expects* a PAnsiChar even if the target window is a UNICODE
+ window. So caling SendMessageA with PChars causes no problems.
+
+ A problem in the VCL has to do with the TControl.Perform() method. Perform()
+ calls the window procedure directly and assumes an ANSI window. This is a
+ problem if, for example, the VCL calls Perform(WM_SETTEXT, ...) passing in a
+ PAnsiChar which eventually gets passed downto DefWindowProcW() which expects a PWideChar.
+
+ This is the reason for SubClassUnicodeControl(). This procedure will subclass the
+ Windows WndProc, and the TWinControl.WindowProc pointer. It will determine if the
+ message came from Windows or if the WindowProc was called directly. It will then
+ call SendMessageA() for Windows to perform proper conversion on certain text messages.
+
+ Another problem has to do with TWinControl.DoKeyPress(). It is called from the WM_CHAR
+ message. It casts the WideChar to an AnsiChar, and sends the resulting character to
+ DefWindowProc. In order to avoid this, the DefWindowProc is subclassed as well. WindowProc
+ will make a WM_CHAR message safe for ANSI handling code by converting the char code to
+ #FF before passing it on. It stores the original WideChar in the .Unused field of TWMChar.
+ The code #FF is converted back to the WideChar before passing onto DefWindowProc.
+}
+
+{
+ Things to consider when designing new controls:
+ 1) Check that a WideString Hint property is published.
+ 2) If descending from TWinControl, override CreateWindowHandle().
+ 3) If not descending from TWinControl, handle CM_HINTSHOW message.
+ 4) Check to make sure that CN_CHAR, CN_SYSCHAR and CM_DIALOGCHAR are handled properly.
+ 5) If descending from TWinControl, verify Unicode chars are preserved after RecreateWnd.
+ 6) Consider using storage specifiers for Hint and Caption properties.
+ 7) If any class could possibly have published WideString properties,
+ override DefineProperties and call TntPersistent_AfterInherited_DefineProperties.
+ 8) Check if TTntThemeManager needs to be updated.
+ 9) Override GetActionLinkClass() and ActionChange().
+ 10) If class updates Application.Hint then update TntApplication.Hint instead.

+{ BACKGROUND: }
+{ TTntMemIniFile buffers all changes to the INI file in memory. To write }
+{ the data from memory back to the associated INI file, call the }
+{ UpdateFile() method. However, the whole content of this INI file will }
+{ be overwritten. Even those sections that are not used. This will make }
+{ troubles, if two instances try to change the same file at the same }
+{ time, without some method of managing access the instances may well end }
+{ up overwriting each other's work. }
+{ }
+{ IDEA: }
+{ TTntMemIniFileEx implementes a simple idea: To check the timestamp }
+{ before each operation. If the file is modified, TTntMemIniFileEx will }
+{ reload the file to keep the content updated. }
+{ }
+{ CONCLUSION: }
+{ # TTntMemIniFileEx and TTntMemIniFile are ideal for read-only access. }
+{ For instance: To read localization files, etc. }
+{ # To perform mass WriteString() operations, please use the following }
+{ code. }
+{ BeginUpdate(); }
+{ try }
+{ for I := 0 to 10000 do }
+{ WriteString(...); }
+{ finally; }
+{ EndUpdate(); }
