#CS UDF Info
;Extended (advanced) function to block mouse & keyboard inputs.
;
; This UDF supports few features that built-in BlockInput() function does not.
; Here is a quick "features list":
;----------------------------------------------------------------------
;* Block seperately mouse or keyboard input.
;* Block specific keyboard/mouse keys/clicks.
; [+] Not only hex keys are supported, string keys (such as {ENTER}) is also valid.
;* Block all keyboard/mouse keys *except* specific keys/events.
;* Block keys by CLASS Name (see UDF documentation).
;* Block inputs only for specific window.
;* BlockInput does not re-enables input after pressing Ctrl+Alt+Del.
;----------------------------------------------------------------------
;
; AutoIt Version: 3.2.12.1+
; Author: G.Sandler (a.k.a MrCreatoR). Initial idea and hooks example by rasim.
;
; Remarks: This UDF, same as built-in BlockInput function, can not block Ctrl+Alt+Del, however, it will not re-enable the input.
;
;
;==================
; History version:
;==================
; [v1.8 - 12.05.2013, 12:16]
; * Fixed issue when some numeric keyboard keys was not blocked.
; * Fixed issue when ALT+Tab was not blocked.
; [v1.7 - 04.05.2012, 18:45]
; * Now by default the UDF affects only on user-input, the same as standard BlockInput function. Can be changed with additional parameter $iBlockAllInput, if set to 1, then all input will be blocked, not just the user's.
; * Added optional parameter $iBlockAllInput to allow block only user-input (default 0, block only user-input).
; * Minor fixes.
;
; [v1.6 - 04.04.2011, 22:30]
; * Fixed (again, caused by fix with re-enabled input) an issue with held down "Alt + Ctrl" keys after the user was called "Alt + Ctrl + Del".
; * Fixed an issue with wrong parameter passed to _WinAPI_CallNextHookEx. Thanks to Ascend4nt.
; + Added remarks to the UDF header.
; + Added "Example - Block TaskMan.au3".
;
; [v1.5 - 11.10.2010, 22:20]
; * Fixed an issue with re-enabled input after pressing Ctrl+Alt+Del.
; * Now the $hWindows parameter can be used for mouse blocking.
; For that reason the $i_MouseHookGetAncestorHwnd variable was added to the UDF,
; if user sets it to 0, then the $hWindows is compared to currently hovered window handle, otherwise (1 - default) it's compared to ancestor of the hovered window/control.
;
; [v1.4 - 03.08.2010, 12:00]
; + AutoIt 3.3.6.1 support.
; * Fixed an issue with held down "Alt + Ctrl" keys after the user was called "Alt + Ctrl + Del". It was causing a problems to use HotKeySet later.
; * Fixed examples to be compatible with AutoIt 3.3.6.1.
; * Minor "cosmetic" changes.
;
; [v1.3 - 24.09.2009, 23:00]
; + Added _BlockInputEx Example (Pass Lock)
; * Fixed few examples.
; * Fixed spell mistakes in the UDF.
;
; [v1.2 - 16.01.2009, 21:00]
; + Added key strings support.
; Now users can set simple hotkey strings for Exclude/Include parameters + Group chars, i.e: "[Group]|{UP}|{DOWN}"
; (See UDF documentation)
; + Added mouse events blocking support to the $sExclude/$sInclude parameters.
; + Added example for mouse events blocking.
;
; [v1.1 - 16.01.2009]
; + Added CLASSes support (see UDF documentation), thanks to FireFox for the idea and the keys lists.
; + Added example for CLASS usage.
; * Changed behaviour of $iBlockMode parameter as following:
;
; 1 - Block All
; <= 0 - UnBlock all
; 2 - Block only mouse
; 3 - Block only keyboard.
;
; * Fixed hard-crash that related to incorrect BlockInput releasing process (only callbacks was released, not the window hooks).
;
; [v1.0 - 15.01.2009]
; First release.

; Name...........: _BlockInputEx
; Description ...: Disable/enable the mouse and/or keyboard. Supporting blocking (by include/exclude) of seperate keys.
; Syntax.........: _BlockInputEx( [iBlockMode [, sExclude [, sInclude [, hWindows [, $iBlockAllInput]]]]] )
;
; Parameters ....: $iBlockMode - [Optional] Set the block mode.
; 1 - Block All
; <= 0 - UnBlock all
; 2 - Block only mouse
; 3 - Block only keyboard.
;
; $sExclude - [Optional] Keys hex/string-list (| delimited) to *exclude* when blocking.
; [*] All keys will be blocked, except the keys in $sExclude list.
; [!] This list supports keys CLASSes,
; key strings as supported in HotKeySet() function,
; and seperate mouse events classes, see "Remarks" for more details.
;
;
;
; $sInclude - [Optional] Keys hex/string-list (| delimited) to *include* when blocking.
; [*] Only these keys will be blocked, the $sExclude ignored in this case.
; [!] This list supports keys CLASSes,
; key strings as supported in HotKeySet() function,
; and seperate mouse events classes, see "Remarks" for more details.
;
; $hWindows - [Optional] Window handles list (| delimited) to limit the blocking process.
;
; $iBlockAllInput - [Optional] If this parameter is 0 (default),
; then only user input will be blocked (the same behaviour as standard BlockInput function), otherwise all input will be blocked (including *Send and Mouse* functions).
;
; Return values .: Success - 1.
; Failure - 0 and set @error to 1. This can happend only when passing wrong parameters.
;
; Author ........: G.Sandler (a.k.a MrCreatoR), Rasim -> Initial idea and hooks example.
; Thanks to FireFox for other block methods, it gave me a starting point for adding the "keys classes" support.
;
;
; Modified.......:
; Remarks .......: * This UDF includes OnAutoItExit function to release the callback/hooks resources.
;
; * $sExclude and $sInclude parameters supporting keys/mouse classes as hex or as string,
; [!] The hex keys list can be found in _IsPressed documentation section.
; Here is a full list of supported classess/events:
; ======= KeyBoard =======
; [:FUNC:]
; [:ALPHA:]
; [:NUMBER:]
; [:ARROWS:]
; [:SPECIAL:]
; [GROUP_abcd] -> Use raw chars/key strings inside squere brackets.
; {KEY} -> Standard keys support ({F1}, {ENTER} etc.).
;
; ========= Mouse =========
; {MMOVE} -> Mouse move event
; {MPDOWN} -> Mouse Primary Down event
; {MPUP} -> Mouse Primary Up event
; {MSDOWN} -> Mouse Secondary Down event
; {MSUP} -> Mouse Secondary Up event
; {MWDOWN} -> Mouse WHEEL Button Down event
; {MWUP} -> Mouse WHEEL Button Up event
; {MWSCROLL} -> Mouse WHEEL Scroll event
; {MSPDOWN} -> Mouse Special Button Down event
; {MSPUP} -> Mouse Special Button Up event
;
;
; * See also built-in BlockInput() documentation.
