Here is my method, based solely on UI Automation API, without focusing windows and sending click events or hotkeys. How can I do it?įor those desperate souls, still searching for an answer. I need to select certain tab item using UI Automation. String value = (()edit.GetCurrentPattern(ValuePattern.Pattern)).Current.Value loop through all the tabs and get the names which is the page titleĬondition condTabItem = new Propert圜ondition(AutomationElement.ControlTypeProperty, ControlType.TabItem) įoreach (AutomationElement tabitem in root.FindAll(TreeScope.Descendants, condTabItem))Ĭondition condUrl = new Propert圜ondition(AutomationElement.ControlTypeProperty, ControlType.Edit) įoreach (AutomationElement edit in root.FindAll(TreeScope.Descendants, condUrl)) TreeWalker treewalker = TreeWalker.ControlViewWalker ĪutomationElement elmTabStrip = treewalker.GetParent(elmNewTab) get the tabstrip by getting the parent of the 'new tab' button If (chrome.MainWindowHandle = IntPtr.Zero)ĪutomationElement root = AutomationElement.FromHandle(chrome.MainWindowHandle) Ĭondition condNewTab = new Propert圜ondition(AutomationElement.NameProperty, "Nueva pestaña") ĪutomationElement elmNewTab = root.FindFirst(TreeScope.Descendants, condNewTab) This shouldn't be a big problem as on websites like YouTube, the media doesn't begin playing unless you have switched at least once to that tab.I am using this code from a C# application to find a tab in Google Chrome: Process procsChrome = Process.GetProcessesByName("chrome") Note that although it does mute inactive tabs, it doesn't actually stop the video/audio in those tabs from playing automatically. You will see as you switch tabs in Chrome after installing it that it handles this audio behavior on-the-fly quite efficiently. To disable it temporarily, click on its toolbar button again. Click on it to turn on automatic muting of all inactive tabs! Then install this extension and it will add a button to the toolbar. Click the Enable link under the flag description and relaunch the browser as suggested:.Type or paste the following text in the Chrome address bar: chrome://flags/#enable-tab-audio-muting. In order to make it work, you first have to enable the Google Chrome flag to turn on audio indicators for each tab using the chrome://flags page. Get the Really Mute Inactive Tabs LT extension The extension is called Really Mute Inactive Tabs LT. A Chrome extension instead handles this automatically muting all background tabs and keeping the active tab's audio unmuted. While you can mute only the tab playing the audio, you still have to locate it and then mute it. While you can either completely mute your system volume, it is not convenient to do so and unmute it every time you need to listen to something. When you are browsing the web, you may be opening multiple tabs and it is very annoying when a tab which is in the background starts playing audio suddenly without even it being focused.
