我有第三方应用程序，我没有自己创建。我需要创建一个能够监听按钮点击并从该应用程序中的表中读取数据的应用程序。我相信第三方应用程序是用C＃编写的，但我不确定。有没有办法知道何时按下UI按钮并从应用程序中获取数据？我不介意解决方案必须编写哪种编程语言，只要它能完成上述任务。
答案 0 :(得分：1)
你可以使用像user32.dll这样的dll来获取其他应用程序的数据。 查找窗口的父句柄：

之后，找到子窗口的句柄
select
dv.division_name,
count(e.empid) as employee_count
from
(
select d.division_id, d.division_name, d.division_name as office_name
from test_division d
union all
select d.division_id, d.division_name, sd.subdivision_name as office_name
from test_div_subdiv_mapping sd
join test_division d on d.division_name = sd.division_id
) dv
join test_m_office o on o.office_name = dv.office_name
left join test_employeelist e on e.office_id = o.office_id
group by dv.division_id, dv.division_name;
并从中获取文字：
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
public static IntPtr FindWindow(string windowName)
{
var hWnd = FindWindow(windowName, null);
return hWnd;
}
//我没有测试这段代码，只是提出了一个想法。 有关更多信息，请访问www.pinvoke.net/default.aspx/。你可以找到很多关于user32.dll
