在AutoIt的帮助文档中， 提到可以用 ControlCommand函数判断checkbox是否选中，有个参数叫“IsChecked”, 但在实际的使用中，至少对.net的checkbox控件无效，网上有人给出了解决方法，原文地址：

他自定义了一个方法，根据选中时控件的颜色变化来判断状态，这是一种新的思路。

Func CheckboxIsChecked($strWindowTitle, $strWindowText, $strCheckboxId);===============================================================================; Function Name: CheckboxIsChecked();   Description: Determines checkbox state using difference in color luminosity.;               A pixel within the checkmark, which significantly changes its;               luminosity based on the IsChecked value, is compared to a pixel;               that has luminosity that's relatively unaffected by IsChecked ;               state. The absolute difference can accommodate a variety of;               user color schemes.;               The location of the two pixels is relative to the upper left ;               corner of the control. These pixels were selected to provide ;               large contrast in both WinXP and Vista, with the checkbox both;               enabled and disabled. Other versions of Windows may require;               other pixels (e.g., older Windows uses an 'x' rather than tick);               or a different threshold; use a Select Case @OSVersion to ;               choose the best pixel pairs.;               Procedure:;                 1. get starting position (upper left corner of checkbox);                    which is defined as (0,0);                 2. get colors of two pixels: checkmark at (8,6) and baseline;                    at (8,11);                 3. place in RGB array to facilitate Min/Max calc;                 4. calculate luminousity of each pixel (Max+Min)/2;                 5. if luminousity difference > threshold then IsChecked=True;        Entry: $strWindowTitle is control's owner window;               $strWindowText is window text;               $strCheckboxId is ID of control to be examined;      Returns: 1 if IsChecked=True, otherwise 0;      Created: 2008-01-09;       Author: Ed Allwein, Active Sensing, Inc.  www.BuyPLM.com;===============================================================================    Local Enum $rgblRed=0, $rgblGreen=1, $rgblBlue=2, $rgblLum=3    Const $maskRed = 0x0FF0000    Const $maskGreen = 0x0FF00    Const $maskBlue = 0x0FF    Const $intThreshold = 26; good UI practice suggests at least 10% diff on scale of 0-255        Local $rectControl[4]    $rectControl = ControlGetPos($strWindowTitle, $strWindowText, $strCheckboxId)    Local $posX = 0 ; X offset from upper left corner of checkbox    Local $posY = 0 ; Y offset from upper left corner of checkbox; baseline pixel luminosity should be relatively stable regardless of checkmark luminosity    $posX = 8   ; baseline X offset    $posY = 11  ; baseline Y offset    Local $rgblBaseline[4]    $rgblBaseline = GetColorAsRGBL($rectControl[0]+$posX,$rectControl[1]+$posY); checkmark pixel should alternate between 2 luminosities (one of which is similar to baseline)    $posX = 8   ; checkmark X offset    $posY = 6   ; checkmark Y offset    Local $rgblCheckmark[4]    $rgblCheckmark = GetColorAsRGBL($rectControl[0]+$posX,$rectControl[1]+$posY)    If Abs($rgblBaseline[$rgblLum] - $rgblCheckmark[$rgblLum]) > $intThreshold Then        Return 1    ;notable luminousity difference between checkmark and baseline    Else        Return 0    EndIf EndFunc  Func GetColorAsRGBL($posX,$posY);===============================================================================; Function Name: GetColorAsRGBL();   Description: returns an array containing (R,G,B,Lum) values.
