Question

我有一个带有几个色带的Excel AddIn，一个色带是设置窗口。单击它时，将显示自定义窗口。但是，单击时没有任何显示。我在日志文件中看到以下异常。是什么导致这种情况以及如何解决？非常感谢

单击功能区时，将执行代码，ConnectionSetup是上面的xaml文件

private bool GetSettings()
{
    var settingUI = new ConnectionSetup();
    settingUI.DataContext = Settings;

    CenterMainWindow(settingUI, wndHandle.Handle);

    bool? result = settingUI.ShowDialog();
    return result ?? false;
}

    private void CenterMainWindow(System.Windows.Window window, IntPtr ownerHandle)
    {
        var helper = new System.Windows.Interop.WindowInteropHelper(window) {Owner = ownerHandle};

        // Center window
        // Note - Need to use HwndSource to get handle to WPF owned window,
        //        and the handle only exists when SourceInitialized has been
        //        raised

        window.SourceInitialized += delegate
                                        {
                                            // Get WPF size and location for non-WPF owner window

~~从您发布的错误堆栈判断，您的设置窗口可能上面有一个链接。不幸的是，链接中包含一个无效的URL，导致窗口的创建失败。~~

编辑：仔细查看了您的代码和错误消息，很明显我正在查找错误的区域。有些搜索在bug中显示为wpf。

短版本：目标机器上的windir环境变量可能设置不正确，导致字体子系统中断。解决方法是通过在启动时添加以下内容来修复目标机器的注册表或代码中的环境变量：

Environment.SetEnvironmentVariable("windir", Environment.GetEnvironmentVariable("SystemRoot"));

我们有几个人遇到过这个问题。所描述的解决方案here（由PATH引起的大于2048个字符）解决了这个问题。

Answer 3

我担心上面提到的声明在使用太多或太少特权的代码中可能会出现问题。当然我的应用程序在我的工作站上运行与我作为管理员这个调用没有问题 Environment.SetEnvironmentVariable（ “WINDIR”，Environment.GetEnvironmentVariable（ “SYSTEMROOT”））;

但我不确定SetEnvironmentVariable是否真的可以在锁定的操作系统上运行。有没有人a）尝试过这个真实的b）在低权限的环境中尝试过它＆gt;

此外，我在使用此调用安装应用程序后，在app启动时看到一些奇怪的内容，并运行一次。所有其他应用程序不再能看到windir，它没有扩展到C：\ Windows。我将完成整个安装并在没有它的情况下运行，看看是否重新出现TypeInvocation异常，或者是否保持OS windir变量保持不变。

更新：

我已经确认我注意到的不良行为是由于未指定SetEnvironment调用的目标。使用以下我的问题似乎已经缓解：

System.Environment.SetEnvironmentVariable("windir", System.Environment.GetEnvironmentVariable("SystemRoot"), EnvironmentVariableTarget.User);

当我没有设置目标时，我的Windows会话发生了非常奇怪的事情，要求我注销和登录甚至重启。因此，除非这种变化真的是在机器或过程级别，否则不要假设使用默认值
