我尝试使用SendMessage函数在Sage应用程序中单击按钮，还使用Spy++获取按钮ID，但我不确定是否正确使用了它：

        private void button2_Click(object sender, EventArgs e)
        {
            IntPtr WindowHandle = FindWindow(null, "Sage 50 Accounts Professional");
            SetForegroundWindow(WindowHandle);

            const int WM_COMMAND = 0x0111;
            const int btn = 0x12EEA720;
            SendMessage(WindowHandle, WM_COMMAND, btn, 0);
        }
我该怎么做才能让它工作？如何向所选按钮/标签等发送操作。？我在MS文档中搜索过，但这对我来说似乎不清楚

我希望我的应用程序单击此按钮：

在您的程序中，您正在向“Sage 50 Accounts Professional window”发送消息WM_命令，而不是特定的UI控件，如按钮或标签

来自MSDN

SendMessage（）将指定的消息发送到一个或多个窗口。发送消息 函数调用指定窗口的窗口过程，并执行以下操作 直到窗口过程处理完消息后才返回

spy++自动化的主要步骤
  • 确定您的应用程序类型，要调查64位应用程序，您需要启动spyxx_amd64.exe，否则您可以使用常规的spyxx.exe

  • 首先研究希望向其发送消息的UI控件的窗口处理程序。我已经使用spy++调查了按钮控件，并生成了下图

  • 识别
    lpszWindow
    的值，这是
    FindWindowEx（）
    的第四个参数。这可能很棘手，有时您可能不知道按钮的真实名称，有时它可能会以
    &buttonext
    作为前缀，有时它可能不会有什么不同。 在上面的示例中，
    按钮
    的lpszWindow的值是
    按钮文本

  • 识别可从Spy++中找到的
    SendMessage（）
    的第二个参数值，即
    uInt32 Msg
    。根据下图，其值为
    0x0201

  • 识别要向其发送消息的控件的第一个参数的值，该参数是
    窗口hwnd句柄
解决方案：

  • 与WinForm应用程序交互的控制台应用程序（请参阅代码中的内联注释）

  • 简单Winform App重新创建问题
