获取第二个IE窗口在不同的显示器上打开

Question

我正在写一个应该作为计划任务运行的.exe文件，以检查是否需要在特定显示器上打开运行.Xbaps的IE窗口。我有一个检查应该运行哪些网址的代码，如果它不是我使用此代码来启动它，然后将其移动到正确的显示器：

Process myProcess = Process.Start("iexplore.exe", "-new -k " + "http://server01:123/software.client.xbap"); 
myProcess.WaitForInputIdle(); 
Thread.Sleep(500); 
MoveWindowToMonitor(myProcess.MainWindowHandle, 1); 

窗口移动代码：

private static void MoveWindowToMonitor(IntPtr windowHandler, int monitor) 
{ 
    RECT windowRec = new RECT(); 
    GetWindowRect(windowHandler, ref windowRec); 

    int width = windowRec.Right - windowRec.Left; 
    int height = windowRec.Top - windowRec.Bottom; 

    if (width < 0) 
     width = width * -1; 

    if (height < 0) 
     height = height * -1; 


    SetWindowPos(windowHandler, (IntPtr)SpecialWindowHandles.HWND_TOP, Screen.AllScreens[monitor].WorkingArea.Left, 
      Screen.AllScreens[monitor].WorkingArea.Top, width, height, SetWindowPosFlags.SWP_SHOWWINDOW); 

} 

运行这是一个快速测试版本，可以打开第一个IE窗口，启动Xbap，然后快速将其移至其他监视器。当我第二次运行它时，没有关闭第一个IE窗口，我总是得到InvalidOperationException

“进程已退出，所以请求的信息不可用。”

我检查我的任务管理器，因为这正在发生，我居然得到详细信息下，我第一次运行任务的任务的每个随后的执行，有两种IEXPLORE.EXE项，只有一个额外的IEXPLORER.EXE 。我还为每个xbap启动一个PresentationHost.exe。

任何人有任何想法我做错了或更好的方式来做到这一点？ 我的最终目标是能够做到这一点：显示器2

启动IE Kiosk模式与特定URL Y：

• 启动IE Kiosk模式监视器1与特定的URL X上

启动IE进程后，它会执行一些有趣的事情，并且您启动的进程可能偶尔会立即结束，因为另一个进程会占用该窗口。

我会做的是，使用下面的方法是EnumTheWindows将逐步通过每个可见的窗口运行，并寻找Internet Explorer或我的baseURL。然后我将该窗口句柄传递给GetURL并获取IE窗口正在运行的特定URL。这使我可以使用ConfirmProcessIsOnProperMonitor（）和MoveWindowToMonitor（）来获取适当监视器上的窗口。

重要的东西：

private static bool ConfirmProcessIsOnProperMonitor(IntPtr windowHandler, int monitor) 
{ 
    //make sure you don't go to an incorrect monitor 
    if (monitor >= Screen.AllScreens.Count()) monitor = Screen.AllScreens.Count() - 1; 

    RECT windowRec = new RECT(); 
    GetWindowRect(windowHandler, ref windowRec); 

    if (windowRec.Left != Screen.AllScreens[monitor].WorkingArea.Left || windowRec.Top != Screen.AllScreens[monitor].WorkingArea.Top) 
     return false; 
    else 
     return true; 
} 

private static void MoveWindowToMonitor(IntPtr windowHandler, int monitor) 
{ 
    //make sure you don't go to an incorrect monitor 
    if (monitor >= Screen.AllScreens.Count()) monitor = Screen.AllScreens.Count() - 1; 

    RECT windowRec = new RECT(); 
    GetWindowRect(windowHandler, ref windowRec); 

    int width = windowRec.Right - windowRec.Left; 
    int height = windowRec.Top - windowRec.Bottom; 

    if (width < 0) 
     width = width * -1; 

    if (height < 0) 
     height = height * -1; 


    SetWindowPos(windowHandler, (IntPtr)SpecialWindowHandles.HWND_TOP, Screen.AllScreens[monitor].WorkingArea.Left, 
      Screen.AllScreens[monitor].WorkingArea.Top, width, height, SetWindowPosFlags.SWP_SHOWWINDOW); 

} 

protected static bool EnumTheWindows(IntPtr hWnd, IntPtr lParam) 
{ 
    int size = GetWindowTextLength(hWnd); 
    if (size++ > 0 && IsWindowVisible(hWnd)) 
    { 
     StringBuilder sb = new StringBuilder(size); 
     GetWindowText(hWnd, sb, size); 
     string windowText = sb.ToString(); 

     if (windowText.ToLower().Contains(_baseURL) || windowText.ToLower().Contains("internet explorer")) 
     { 
      string url = GetURL(hWnd); 
      _windowhandles.Add(hWnd, url); 
     } 
    } 
    return true; 
} 

private static string GetURL(IntPtr intPtr) 
{ 
    foreach (InternetExplorer ie in new ShellWindows()) 
    { 
     if (ie.HWND == intPtr.ToInt32()) 
     { 
      string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(ie.FullName); 
      if ((fileNameWithoutExtension != null) && fileNameWithoutExtension.ToLower().Equals("iexplore")) 
      { 
       return ie.LocationURL; 
      } 
      else 
      { 
       return null; 
      } 
     } 
    } 

    return null; 
}
