AHK计算器GUI复制功能优化：仅复制已填写的QC层级

可以通过**条件判断（If语句）**实现只复制非空的QC层级，核心逻辑是逐个检查每个QC层级的关键变量（比如对应Result值），若不为空则将该层级的文本内容拼接到最终复制字符串中，修改后的代码如下：

Copy:
CopyQC := ""  ; 初始化空字符串

; 检查QC Level 1是否有内容，以Result1为例，可按需调整判断条件
if (Result1 != "") {
    CopyQC .= "QC Level 1:`n"
    CopyQC .= "    Result: " Result1 "`n"
    CopyQC .= "    Lab Range: " LRange1 "`n"
    CopyQC .= "    Peer Mean: " PeerMean1 "`n"
    CopyQC .= "    Peer SD: " PeerSD1 "`n"
    CopyQC .= "    Peer Range: " 1Low " - " 1High "`n"
    CopyQC .= "    Result SDs: " Result1SD "`n`n"
}

; 检查QC Level 2
if (Result2 != "") {
    CopyQC .= "QC Level 2:`n"
    CopyQC .= "    Result: " Result2 "`n"
    CopyQC .= "    Lab Range: " LRange2 "`n"
    CopyQC .= "    Peer Mean: " PeerMean2 "`n"
    CopyQC .= "    Peer SD: " PeerSD2 "`n"
    CopyQC .= "    Peer Range: " 2Low " - " 2High "`n"
    CopyQC .= "    Result SDs: " Result2SD "`n`n"
}

; 检查QC Level 3
if (Result3 != "") {
    CopyQC .= "QC Level 3:`n"
    CopyQC .= "    Result: " Result3 "`n"
    CopyQC .= "    Lab Range: " LRange3 "`n"
    CopyQC .= "    Peer Mean: " PeerMean3 "`n"
    CopyQC .= "    Peer SD: " PeerSD3 "`n"
    CopyQC .= "    Peer Range: " 3Low " - " 3High "`n"
    CopyQC .= "    Result SDs: " Result3SD "`n`n"
}

; 去除末尾多余的换行
CopyQC := RTrim(CopyQC, "`n`r")

; 执行复制操作
Gui, 6: Add, Edit, vCopy, %CopyQC%
Gui, 6: Show
Send, ^c
Gui, 6: Destroy
return

关键说明： #

• 用CopyQC := ""初始化空字符串，避免初始值携带多余内容
• 每个QC层级通过if (ResultX != "")判断是否有效，若需更严格校验（比如该层级所有字段为空才跳过），可修改为if (ResultX != "" || LRangeX != "" || PeerMeanX != "" || ...)
• 用.=运算符拼接字符串，逐步将非空层级内容添加到目标字符串中
• 最后用RTrim清除末尾多余换行，避免粘贴后出现空行
