再问,如何监控ListView中某项是否发生改变?
http://www.autoitx.com/forum.php?mod=viewthread&tid=36601&highlight=ListView就是想问这个帖子里的问题,不过论坛大大说的太精华了,我完全不明白怎么回事啊。
谁能给详细解释下,这里多谢了。 ListView示例中有啊就是消息处理 点ListView查看调试输出#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>
$Debug_LV = False ; 检查传递给 ListView 函数的类名, 设置为True并输出到一个控件的句柄,用于检查它是否工作

如果是自身窗口,用2楼的方法就可以直接捕获
如果是第三方进程,必须注入或全局HOOK处理 好复杂,不懂也
