myProcess.StartInfo.FileName = "D:\\Program Files\\InterVideo\\WinDVR\\WinDvr.exe";

myProcess.StartInfo.UseShellExecute = false;

myProcess.Start();

myProcess.WaitForInputIdle(2000);

IntPtr hWnd = myProcess.MainWindowHandle;

//Console.WriteLine(hWnd);

MessageBox.Show(hWnd.ToString());

SetForegroundWindow(hWnd);

bool p = SetForegroundWindow(hWnd);

if (!p)

MessageBox.Show("Could not set focus");

SendKeys.SendWait("{Home}");
