Question

我正在尝试使用AHK在另一个应用程序中获取listview控件的内容。我尝试使用

ControlGet, List, List,, ListViewWndClass1, WindowTitle

在AutoHotKey中

但这不起作用。有没有办法使用AHK PostMessage / SendMessage或DllCall获取listview控件内容（“SendMessage”？

试试这个：

GetListViewItemText(item_index, sub_index, ctrl_id, win_id) 
    { 
        ;const 
        MAX_TEXT = 260 

        VarSetCapacity(szText, MAX_TEXT, 0) 
        VarSetCapacity(szClass, MAX_TEXT, 0) 
        ControlGet, hListView, Hwnd, , %ctrl_id%, ahk_id %win_id% 
        DllCall("GetClassName", UInt,hListView, Str,szClass, Int,MAX_TEXT) 
        if (DllCall("lstrcmpi", Str,szClass, Str,"SysListView32") == 0 || DllCall("lstrcmpi", Str,szClass, Str,"TListView") == 0) 
        { 
            GetListViewText(hListView, item_index, sub_index, szText, MAX_TEXT) 
        } 

        return %szText% 
    } 

    GetListViewText(hListView, iItem, iSubItem, ByRef lpString, nMaxCount)

应该像这样工作：

WinGet, hWnd, ID, My WinTitle
GetListViewItemText(1, 1, "ListViewWndClass1", hWnd)
