按标题查找窗口窗口的标题是什么? [英] Find Window By Caption what is the caption of the window?

问题描述

我必须跟踪程序的运行时间.该程序公开以下窗口

I have to track the running time of a program. That program exposes the following window

同时我启动我的程序，它在计时器中执行:

At the same time I launch my program which in a timer does:

private void TimerCheckGroups_Tick(object sender, EventArgs e)
{
  IntPtr windowPtr = FindWindowByCaption(IntPtr.Zero, "Execution");
  if (windowPtr != IntPtr.Zero)
    Console.Beep();<--------
}

但是哔声线永远不会被击中.我是否误解了窗口标题的含义?

But the beep line never gets hit. Have I misunderstood the meaning of a window caption?

--添加--我会尽量让执行阶段更清晰.

--ADD-- I'll try to make the execution phases clearer.

启动----> 启动我的记录器.

Startup----> launch my logger.

用户-------> 启动程序 A，启动程序 B(不可见)，启动窗口 C.C 有标题执行.

User-------> launches program A that launches program B (not visible) that launches window C. C has caption Execution.

当我启动 dontbyteme 提出的解决方案时，只有 B 程序出现，所以只有 1 个窗口.

When I launch the solution proposed by dontbyteme the only the B program appears so only 1 window.

简而言之

• logger:不可见，因为它是一个托盘程序

• logger: not visible since it's a tray program

程序 A:可见，因为它是主程序

program A: visible since it's the main program

程序 B:不可见，因为它被设置为不可见

program B: not visible since it's set to Notvisible

程序 C:为什么不可见?！?！?！?

program C: not visible why?!?!?!?

--感谢 JARRETT 的解决方案--

--SOLUTION THANX TO JARRETT--

• logger 通过计时器监控进程保持空闲

• logger stays idle with a timer monitoring processes

程序 A 启动了，但没有人关心它.然后程序 A 启动程序 B

program A starts but nobody cares about it. Then program A launches program B

当程序 B 醒来时，我找到窗口并开始记录

when program B is awake i find the window and start logging

推荐答案

以下问题解决了如何确定程序何时启动.检测应用程序的启动 此外，您可以使用dll 导入并使用 EnumWindows.列出了对您有帮助的示例 pInvokes.

The following question addresses how to find out when programs launch. Detecting the launch of a application Also, you can enumerate windows on your machine with a dll import and using EnumWindows. Sample pInvokes that will help you are listed.

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern bool EnumWindows(EnumWindowsProc enumProc, IntPtr lParam);
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern int GetWindowText(IntPtr hWnd, StringBuilder strText, int maxCount);
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern int GetWindowTextLength(IntPtr hWnd);
    [DllImport("user32.dll")]
    private static extern bool IsWindowVisible(IntPtr hWnd);
