Question

任何人都可以解释，为什么我会得到＆＃34;错误＆＃34;消息框？

我认为，代码可以自我解释。我很惊讶＆＃34;当我发现它由于某种原因而无法工作时。

（当你在打开的记事本窗口中按F1时，你会看到＆＃34;它有效！＆＃34;消息。相反，我得到一个＆＃34;错误＆＃34;消息。）

我已经尝试了不同的方法来解决它，即百分比，变量分配，括号，但目前它仍然无法正常工作。

#SingleInstance, Force
SetTitleMatchMode, 2

f1::
+f1::
GetKeyState, shift_state, Shift
msgbox, %shift_state%
if (WinActive("Notepad") and shift_state = D)
    msgbox, It works! By the way, the Shift key is pressed.
else if (WinActive("Notepad") and shift_state = U)
    msgbox, It works! The Shift key is not pressed.
else
    msgbox, error
return

Answer 1

在表达模式中，文字字符串必须用双引号括起来，以区别于变量。

表达方式：

#SingleInstance, Force 
SetTitleMatchMode, 2

f1::
+f1::
GetKeyState, shift_state, Shift
    msgbox, %shift_state%
if (WinActive("Notepad") and shift_state = "D")
    msgbox, It works! By the way, the Shift key is pressed.
else if (WinActive("Notepad") and shift_state = "U")
    msgbox, It works! The Shift key is not pressed.
else
    msgbox, error
return

传统模式：

#SingleInstance, Force 
SetTitleMatchMode, 2

f1::
+f1::
GetKeyState, shift_state, Shift
    msgbox, %shift_state%
IfWinActive Notepad
{
    If shift_state = D
        msgbox, It works! By the way, the Shift key is pressed.
    else If shift_state = U
        msgbox, It works! The Shift key is not pressed.
}
else
    msgbox, error
return

`如果WinActive`和`GetKeyState`
