我有一个窗口的手柄,我想做的是点击它的按钮名为"加载设置"。我有两个问题。
- 我的第一个问题是当我在某个InvokePattern上调用Invoke时,它会使窗口聚焦,这对我的应用程序来说是不希望的。
-
我的第二个问题是可见的,并记录在我下面代码末尾的注释中:
AutomationElement aeBot = AutomationElement.FromHandle(mbotSettingList.ElementAt(i).getWindowHandle()); AutomationElement aeButtonLoadSettings = aeBot.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Load Settings")); InvokePattern ipClickLoadSettings = (InvokePattern)aeButtonLoadSettings.GetCurrentPattern(InvokePattern.Pattern); Thread invokeLoadSettingsThread = new Thread(ipClickLoadSettings.Invoke); InvokePattern ipClickOpen = null; AutomationElement aeOpenDialogEdit = null; AutomationElement aeButtonOpen = null; AutomationElementCollection aeDialogs = null; AutomationElement aeOpenDialog = null; ValuePattern vpOpenDialogEdit = null; //Using a thread to invoke the Load Settings button click because as a result of clicking Load Settings a dialog is opened and invoke doesnt return for nealy 10 seconds invokeLoadSettingsThread.Start(); //We probably wont join() this thread because it goes on for far longer than we expect to be in this function //Get a collection of the Dialog windows that are direct children of the main window we have a handle to aeDialogs = aeBot.FindAll(TreeScope.Children, new PropertyCondition(AutomationElement.ClassNameProperty, "#32770")); while (aeDialogs.Count == 0) { //This while loop is to continue to check for the Open file dialog as it may take a little time to open aeDialogs = aeBot.FindAll(TreeScope.Children, new PropertyCondition(AutomationElement.ClassNameProperty, "#32770")); Thread.Sleep(250); } for (int j = 0; j < aeDialogs.Count; j++) { //There is usually only 1 child dialog window, but just make sure we have the correct one if (aeDialogs[j].Current.Name == "Open") { Debug.WriteLine("Found open dialog!"); aeOpenDialog = aeDialogs[j]; break; } } //Inside the Open window, the first Edit window is the one where the file name/path should be entered aeOpenDialogEdit = aeOpenDialog.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ClassNameProperty, "Edit")); //Set the value of the file name/path to the string variable "loadSettingsString" vpOpenDialogEdit = (ValuePattern)aeOpenDialogEdit.GetCurrentPattern(ValuePattern.Pattern); vpOpenDialogEdit.SetValue(loadSettingsString); //******************************************PROBLEM BEGINING BELOW****************************************** //Using multiple methods, we can successfully get a successful AutomationElement for the "Open" button in the Open file dialog aeButtonOpen = aeOpenDialog.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.NameProperty, "Open")); //aeButtonOpen = aeOpenDialog.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.NameProperty, "Cancel")); //Something to consider: If we assigned aeButtonOpen to the AutomationElement we find be looking for "Cancel" rather than "Open" Debug.WriteLine(aeButtonOpen.Current.Name + " button found!"); //Prints "Open button found!" //If aeButtonOpen were assigned to "Cancel", this would print "Cancel button found!" ipClickOpen = (InvokePattern)aeButtonOpen.GetCurrentPattern(InvokePattern.Pattern); //GetCurrentPattern has returned null //If aeButtonOpen were assigned to "Cancel", this would NOT be null ipClickOpen.Invoke(); //Invoke() on a null results in "Unsupported Pattern" exception //If aeButtonOpen were assigned to "Cancel", this would work and the Open file dialog would then be exited just as if cancel were clicked
使用UIAVerify查看应用程序的UIA树。看看您的代码,我怀疑您没有检索到您所认为的元素。如果'Open'元素是一个按钮,它应该支持Invoke模式。
或者,您打开一个对话框,然后立即搜索该对话框的子元素。您可能在这里遇到可靠性问题,其中仍在为该对话框创建UIA树。为了检查这个问题,添加一秒钟的睡眠,看看是否解决了你的问题。如果是这种情况,请查看UIA结构更改事件。这些事件将允许您根据UIA树中的更改同步UIA测试代码。
