Return Value Success: Returns 1. Failure: Returns 0 if window is not found. Remarks This function sends a close message to a window, the result depends on the window (it may ask to save data, etc.). To force a window to close, use the WinKill function. If multiple windows match the criteria, the window that was most recently active is closed.

AutoItSetOption ( "option" [, param] ) Parameters option The option to change. See Remarks. param [optional] The value to assign to the option. The type and meaning vary by option. See remarks below. If the param is not provided, then the function just returns the value already assigned to the option. The keyword Default can be used for the parameter to reset the option to its default value. Return Value Returns the value of the previous setting for the option. Remarks You may use Opt() as an alternative to AutoItSetOption(). AutoIt will halt with an error message if the requested option is unknown. Options are as follows: Option Param CaretCoordMode Sets the way coords are used in the caret functions, either absolute coords or coords relative to the current active window: 0 = relative coords to the active window 1 = absolute screen coordinates (default) 2 = relative coords to the client area of the active window ExpandEnvStrings Changes how literal strings and % symbols are interpreted. By default strings are treated literally, this option allows you to use %environment% variables inside strings, e.g., "The temp directory is: %temp%". 1 = expand environment variables (similar to AutoIt v2) 0 = do not expand environment variables (default) Without this option the usual way would be: "The temp directory is: " & EnvGet("temp") ExpandVarStrings Changes how literal strings and variable/macro ($ and @) symbols are interpreted. By default strings are treated literally, this option allows you to use variables and macros inside strings, e.g., "The value of var1 is $var1$". 1 = expand variables (when in this mode and you want to use a literal $ or @ then double it up: "This is a single dollar $$ sign". 0 = do not expand variables (default) FtpBinaryMode Changes how FTP files are transferred. 1 = Binary (default) 0 = ASCII GUICloseOnESC When ESC is pressed on a GUI the $GUI_EVENT_CLOSE message is sent. This option toggles this behavior on and off. 1 = Send the $GUI_EVENT_CLOSE message when ESC is pressed (default). 0 = Don't send the $GUI_EVENT_CLOSE message when ESC is pressed. GUICoordMode Alters the position of a control defined by GUICtrlSetPos. 1 = absolute coordinates (default) still relative to the dialog box. 0 = relative position to the start of the last control (upper left corner). 2 = cell positionining relative to current cell. A -1 for left or top parameter don't increment the start. So next line is -1,offset; next cell is offset,-1; current cell is -1,-1. Obviously "offset" cannot be -1 which reserved to indicate the no increment. But if you can use a multiple of the width you choose to skip or go back. GUIDataSeparatorChar Define the character which delimits subitems in GUICtrlSetData. The default character is '|'. GUIOnEventMode Enable/disable OnEvent functions notifications. 0 = (default) disable. 1 = enable. GUIResizeMode Change default resizing for a control. 0 = (default) keep default control resizing. <1024 = anytype of resizing see GUICtrlSetResizing. GUIEventOptions Change special event behavior or GUI function return values. 0 = (default) Windows behavior on click on Minimize,Restore, Maximize, Resize. 1 = suppress windows behavior on minimize, restore or maximize click button or window resize. Just sends the notification. MouseClickDelay Alters the length of the brief pause in between mouse clicks. Time in milliseconds to pause (default=10). MouseClickDownDelay Alters the length a click is held down before release. Time in milliseconds to pause (default=10). MouseClickDragDelay Alters the length of the brief pause at the start and end of a mouse drag operation. Time in milliseconds to pause (default=250). MouseCoordMode Sets the way coords are used in the mouse functions, either absolute coords or coords relative to the current active window: 0 = relative coords to the active window 1 = absolute screen coordinates (default) 2 = relative coords to the client area of the active window MustDeclareVars If this option is used then all variables must be pre- declared with Dim, Local or Global before they can be used - removes the chance for misspelled variables causing bugs. 1 = Variables must be pre-declared 0 = Variables don't need to be pre-declared (default) OnExitFunc Sets the name of the function called when AutoIt exits (default is OnAutoItExit). PixelCoordMode Sets the way coords are used in the pixel functions, either absolute coords or coords relative to the window defined by hwnd (default active window): 0 = relative coords to the defined window 1 = absolute screen coordinates (default) 2 = relative coords to the client area of the defined window SendAttachMode Specifies if AutoIt attaches input threads when using Send() function. When not attaching (default mode=0) detecting the state of capslock/scrolllock and numlock can be unreliable under NT4. However, when you specify attach mode=1 the Send("{ down/up}") syntax will not work and there may be problems with sending keys to "hung" windows. ControlSend() ALWAYS attaches and is not affected by this mode. 0 = don't attach (default) 1 = attach SendCapslockMode Specifies if AutoIt should store the state of capslock before a Send function and restore it afterwards. 0 = don't store/restore 1 = store and restore (default) SendKeyDelay Alters the the length of the brief pause in between sent keystrokes. A value of 0 removes the delay completely. Time in milliseconds to pause (default=5). SendKeyDownDelay Alters the length of time a key is held down before being released during a keystroke. For applications that take a while to register keypresses (and many games) you may need to raise this value from the default. A value of 0 removes the delay completely. Time in milliseconds to pause (default=5). TCPTimeout Defines the time before TCP functions stop if no communication. Time in milliseconds before timeout (default=100). TrayAutoPause Script pauses when click on tray icon. 0 = no pause 1 = pause (default). If there is no DefaultMenu no pause will occurs. TrayIconDebug If enabled shows the current script line in the tray icon tip to help debugging. 0 = no debug information (default) 1 = show debug TrayIconHide Hides the AutoIt tray icon. Note: The icon will still initially appear ~750 milliseconds. 0 = show icon (default) 1 = hide icon . functions/parameters.
