我有此代码用于将鼠标操作发送到非活动窗口，但我不知道为什么它不起作用，并且它没有给出任何错误。在此示例中，我想在 Paint 中画一条线。
#include <SendMessage.au3>
#include <WinAPI.au3>
Global $wHandle = "Untitled - Paint"
ControlClickDrag($wHandle,"left",300,300,100,80)
Func ControlClickDrag($wHandle, $Button="left", $X1="", $Y1="", $X2="", $Y2="")
Local $MK_LBUTTON = 0x0001
Local $WM_LBUTTONDOWN = 0x0201
Local $WM_LBUTTONUP = 0x0202
Local $MK_RBUTTON = 0x0002
Local $WM_RBUTTONDOWN = 0x0204
Local $WM_RBUTTONUP = 0x0205
Local $WM_MOUSEMOVE = 0x0200
Local $i = 0
Select
Case $Button = "left"
$Button = $MK_LBUTTON
$ButtonDown = $WM_LBUTTONDOWN
$ButtonUp = $WM_LBUTTONUP
Case $Button = "right"
$Button = $MK_RBUTTON
$ButtonDown = $WM_RBUTTONDOWN
$ButtonUp = $WM_RBUTTONUP
EndSelect
DllCall("user32.dll", "int", "SendMessage", "hwnd", $wHandle, "int", $ButtonDown, "int", $Button, "long", _MakeLong($X1, $Y1))
DllCall("user32.dll", "int", "SendMessage", "hwnd", $wHandle, "int", $ButtonUp, "int", $Button, "long", _MakeLong($X2, $Y2))
EndFunc
Func _MakeLong($LoWord,$HiWord)
Return BitOR($HiWord * 0x10000, BitAND($LoWord, 0xFFFF))
EndFunc
