copied!<p>I'm trying to write a simple console program that will launch device manager and by using keystrokes, navigate though it. So far i cannot get they key stroke to register in Device manager. </p> <p>The program launches device manager fine but no keystrokes seem to be working inside device manager. I know the tree part of device manager is called SysTreeView32 by using Spy++. </p> <p>Any suggestions? </p> <p>Here is my code so far. </p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; using System.Windows.Forms; using System.Threading; using System.Runtime.InteropServices; namespace Dev_Mgr_Auto { class Program { [DllImport("user32.dll", EntryPoint = "FindWindow")] private static extern IntPtr FindWindow(string lp1, string lp2); [DllImport("user32.dll", ExactSpelling = true, CharSet = CharSet.Auto)] [return: MarshalAs(UnmanagedType.Bool)] private static extern bool SetForegroundWindow(IntPtr hWnd); static void Main(string[] args) { //start Device Manager Process.Start("devmgmt.msc"); Thread.Sleep(1500); // find window handle of Device manager IntPtr handle = FindWindow("MMCMainFrame", "Device Manager"); if (!handle.Equals(IntPtr.Zero)) { // activate Device Danager window if (SetForegroundWindow(handle)) { // send key "Tab" SendKeys.SendWait("{TAB}"); // send key "Down" x 4 SendKeys.SendWait("DOWN 4"); } } }//end main }//end class }// end program </code></pre> <p><strong>EDIT1: You must run the program as administrator for it to work.</strong> </p> <p>Final Code: </p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; using System.Windows.Forms; using System.Threading; using System.Runtime.InteropServices; using System.Windows.Automation; namespace Video_Card_Updater { class Program { [DllImport("user32.dll", EntryPoint = "FindWindow")] private static extern IntPtr FindWindow(string lp1, string lp2); [DllImport("user32.dll", ExactSpelling = true, CharSet = CharSet.Auto)] [return: MarshalAs(UnmanagedType.Bool)] private static extern bool SetForegroundWindow(IntPtr hWnd); [DllImport("user32.dll", CharSet = CharSet.Auto)] static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam); static void Main(string[] args) { // this code needs a reference to UIAutomationClient and UIAutomationTypes Process process = Process.Start("devmgmt.msc"); do { process.Refresh(); Thread.Sleep(100); } while (process.MainWindowHandle == IntPtr.Zero); // get root element that corresponds to the process main window AutomationElement mainWindow = AutomationElement.FromHandle(process.MainWindowHandle); // get the first tree view control by its class name AutomationElement treeView = mainWindow.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.ClassNameProperty, "SysTreeView32")); // get the "Keyboards" node by its name AutomationElement Display = treeView.FindFirst(TreeScope.Subtree, new PropertyCondition(AutomationElement.NameProperty, "Display adapters")); // expand item ((ExpandCollapsePattern)Display.GetCurrentPattern(ExpandCollapsePattern.Pattern)).Expand(); // get first display AutomationElement firstDisplay = Display.FindFirst(TreeScope.Children, PropertyCondition.TrueCondition); // set focus to display and do the following key commands: firstDisplay.SetFocus(); SendKeys.SendWait("{ENTER}"); Thread.Sleep(100); SendKeys.SendWait("{TAB 3}"); Thread.Sleep(100); SendKeys.SendWait("{RIGHT}"); Thread.Sleep(100); //ALT + P SendKeys.SendWait("%P"); Thread.Sleep(100); SendKeys.SendWait("{ENTER}"); } // end main }//end class }// end program </code></pre>
