無法獲取AutoHotkey來評估if語句中的變量

Question

我試圖讓AutoHotkey對從剪貼板分配的變量進行求值，然後根據變量做些什麼。下面的代碼：

^j:: 
    Clipboard := ""   ; Must start off blank for detection to work. 
    WinActivate, ahk_exe Excel.exe 

    Send, ^c      ; Copy text into Clipboard 
    ClipWait, 2      ; wait for it to be copied 
    Course := Clipboard    ; Fetch the text into variable 
    Clipboard := ""     ; Reset Clipboard 

    MsgBox %Course%     ; To test is Course is "103" 

    if (Course == 103) 
    { 
     Correct_Num := 105 
     Correct_Title := Art Appreciation 
    } 

    send, {Tab} 
    send, {Tab} 
    send, {Tab} 
    send, %Correct_Num% 
    send, {Tab} 
    send, %Correct_Title% 

if語句沒有檢測到Course == 103儘管顯示103，我試着寫在報價與103的聲明中MSGBOX，我已經試過IfEqual。不知道還有什麼要做。

所有的變量（剪貼板，課程，Correct_Num和Correct_Title）必須從空白處開始檢測才能正常工作。否則，它們的最後一個值將保留在內存中

^j:: 
    Course := "" 
    Correct_Num := "" 
    Correct_Title := "" 
    Clipboard := ""   
    WinActivate, ahk_exe Excel.exe 
    WinWaitActive, ahk_exe Excel.exe ; important 
    Send, ^c       ; Copy the preselected text 
    ClipWait, 2      ; Wait for the clipboard to contain data 
    if (!ErrorLevel)     ; If NOT ErrorLevel clipwait found data on the clipboard 
    { 
     Course := Trim(Clipboard)  ; Fetch the text into variable (as suggested by PGilm) 
     Clipboard := ""     ; Reset Clipboard 
     if (Course == 103) 
     { 
      Correct_Num = 105 
      Correct_Title = Art Appreciation 
     } 
     MsgBox %Course%`n%Correct_Num%`n%Correct_Title% 
    } 
    else 
     MsgBox, The attempt to copy text onto the clipboard failed. 
return

每我的評論：

^j:: 
    Clipboard := ""   ; Must start off blank for detection to work. 
    WinActivate, ahk_exe Excel.exe 

    WinWaitActive, ahk_exe Excel.exe ; important 

    Send, ^c       ; Copy text into Clipboard 
    ClipWait, 2      ; wait for it to be copied 
    Course := Trim(Clipboard)  ; Fetch the text into variable 
    Clipboard := ""     ; Reset Clipboard 

    MsgBox %Course%     ; To test is Course is "103" 

    Correct_Num =     ; Clear variables per user3419297 so they don't 
    Correct_Title =     ; contain the results from a prior time the equality 
            ; was satisfied (else you will get the same results 
            ; even if Course <> 103 since those variables 
            ; will still contain the values from earlier) 

    ifEqual, Course, 103 
    { 
     MsgBox Course is equal to 103, Hooray!! 
     Correct_Num := 105 
     Correct_Title := Art Appreciation 
    } 

    send, {Tab} 
    send, {Tab} 
    send, {Tab} 
    send, %Correct_Num% ; will be blank (send nothing) if course not 103 
    send, {Tab} 
    send, %Correct_Title% ; will be blank (send nothing) if course not 103 

    ; return ; not sure what the rest of your code does
