[已解决],#forceref的含义
本帖最后由 529304mnm 于 2010-8-3 21:19 编辑如题，论坛上有人问但是没有解决。大侠们帮忙啊！ 同问，一直没搞懂#forceref有何意义。
或者只是如;注释符号、#Engion那样，仅起到一个注释的作用？~ 要忽略的参数吧，猜的 http://www.autoitscript.com/forum/index.php?showtopic=39310

看来就如我说，忽略（不使用的）变量
我一直是这样用的… 强制作为参考参数（即后面跟随的参数只是占个位置，屁用没有） 本帖最后由 C.L 于 2010-7-31 23:56 编辑

正解
下面提供一段代码
#AutoIt3Wrapper_Run_AU3Check=Y
#AutoIt3Wrapper_Au3Check_Parameters = -w 5
hello (2)
Func hello($hello)
;~ #forceref $hello
msgbox(0,"","Hello World!")
EndFunc先将#forceref注释了，将这段代码编译成exe时，au3check 会出现错误提示：
C:\Users\xx\Desktop\test.au3(7,18) : WARNING: $hello: declared, but not used in func.
Func hello($hello)
~~~~~~~~~~~~~~~~~^
而将#forceref $hello的注释去掉，再编译就没有错误出现了。 如果这样说,这个函数基本没啥用啊..... 是给编译器看的 本帖最后由 lchl0588 于 2010-8-1 19:01 编辑

#Include <GuiListView.au3>
$Form1 = GUICreate("AForm1", 452, 199, 177, 118)

看下25行中！！！
