Visual Studio 2010的HWND

Question

有没有办法从VSIX扩展程序中获取HWND指针到达Visual Studio 2010的顶部窗口？ （我想更改窗口的标题）。

Answer 1

由于您的VSIX扩展名将与Visual Studio进行内部处理，因此您应该尝试以下操作：

System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle

（请注意，如果您执行得太早，您将获得VS Splash屏幕...）

Answer 2

我假设您想在C＃中以编程方式进行此操作？

您需要在课内定义此P/调用：

[DllImport("user32.dll")]
static extern int SetWindowText(IntPtr hWnd, string text);

然后有一些看起来与以下几个相似的代码：

Process visualStudioProcess = null;
//Process[] allProcesses = Process.GetProcessesByName("VCSExpress"); // Only do this if you know the exact process name
// Grab all of the currently running processes
Process[] allProcesses = Process.GetProcesses();
foreach (Process process in allProcesses)
{
    // My process is called "VCSExpress" because I have C# Express, but for as long as I've known, it's been called "devenv". Change this as required
    if (process.ProcessName.ToLower() == "vcsexpress" ||
        process.ProcessName.ToLower() == "devenv"
        /* Other possibilities*/)
    {
        // We have found the process we were looking for
        visualStudioProcess = process;
        break;
    }
}

// This is done outside of the loop because I'm assuming you may want to do other things with the process
if (visualStudioProcess != null)
{
    SetWindowText(visualStudioProcess.MainWindowHandle, "Hello World");
}

在我的本地尝试此代码，它似乎设置了窗口标题，但是Visual Studio在许多条件下覆盖它：获得焦点，输入/叶子调试模式...这可能很麻烦。

注意：您可以直接从进程对象获取窗口标题，但不能设置它。

您可以使用 Envdte API 要获取主窗口的HWND：

var hwndMainWindow = (IntPtr) dte.MainWindow.HWnd;

在Visual Studio 2010/2012中，使用WPF实现的主窗口和一部分用户控件。您可以立即获取主窗口的WPF窗口并使用它。我为此写了以下扩展方法：

public static Window GetWpfMainWindow(this EnvDTE.DTE dte)
{
  if (dte == null)
  {
    throw new ArgumentNullException("dte");
  }

  var hwndMainWindow = (IntPtr)dte.MainWindow.HWnd;
  if (hwndMainWindow == IntPtr.Zero)
  {
    throw new NullReferenceException("DTE.MainWindow.HWnd is null.");
  }

  var hwndSource = HwndSource.FromHwnd(hwndMainWindow);
  if (hwndSource == null)
  {
    throw new NullReferenceException("HwndSource for DTE.MainWindow is null.");
  }

  return (Window) hwndSource.RootVisual;
}
