这个按钮的奇特之处在于它没有hwnd值。(hwnd:0x0)。以下是我试图获取按钮参考的内容:
currentWindow = FindWindowEx((IntPtr)hwnd, IntPtr.Zero, null, "Options");
在本例中,hwnd变量是包含按钮的应用程序主窗口的句柄
在阅读FindWindowEx的文档时,似乎有多种使用不同参数的方法,我觉得我已经尝试了所有这些方法。我在类参数中尝试了“NetUISimpleButton”和“Button”。我在窗口名和控件“Options”的名称中尝试了null,如上所示。我在这两个字段中尝试了所有这些值的组合。我还尝试为child after指定一个值,使其成为主窗口的子窗口。我甚至试着把IntPtr.0作为第一个参数
我开始认为这个hwnd:0x0是一个不祥的预兆,这意味着我根本没有访问这个按钮的选项。如果是这样,我还有其他选择吗?我只是想在应用程序中打开一个辅助窗口,这样我就可以再点击几个按钮和单选按钮。用户界面自动化非常简单。这是我使用的代码,以防有人感兴趣
int hwnd = FindWindow("CommunicatorMainWindowClass", null);
AutomationElement lync = AutomationElement.FromHandle((IntPtr)hwnd);
AutomationElement optionsButton = lync.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Options"));
((InvokePattern)optionsButton.GetCurrentPattern(InvokePattern.Pattern)).Invoke();

有些按钮不是窗口,因此没有手柄。你需要使用。很棒的arx。真是太棒了!我将在下面的答案中发布我的代码。有些按钮不是窗口,所以它们没有句柄。你需要使用。很棒的arx。真是太棒了!我将在下面的答案中发布我的代码。
