问题描述

我有一个Excel外接程序与几个丝带，一是色带设置窗口。
当它被点击，自定义窗口会显示出来。
然而，没有什么单击时露面。
我看到在日志文件中的下列情况除外。是什么原因导致这个问题以及如何解决它？非常感谢

解决方案

<击>从看您发布错误堆栈，看来您的设置窗口中可能有它的链接。不幸的是，链接中有一个无效的URL，这将导致窗口创建失败



编辑：
已经更加紧密地看着你的代码和错误消息，很明显，我是在找错了地方。一些搜索变成了一个错误 WPF 。



短的版本：WINDIR环境变量可能正确目标机器，这将导致该字体subsytem打破上设置。解决方法是修复环境变量，无论是在目标机器的注册表，或在代码中加入类似以下的启动：

  Environment.SetEnvironmentVariable（WINDIR，Environment.GetEnvironmentVariable（SYSTEMROOT））;


I have an Excel AddIn with several ribbons, one ribbon is setting window. When it is clicked, a custom window will show up. However, there is nothing to show up when clicked. I saw the following exceptions in log file. What causes this and how to fix it? thanks a lot

解决方案

Judging from the error stack you posted, it appears that your settings window probably has a link on it. Unfortunately, the link has an invalid url in it, which causes the creation of the window to fail.

EDIT: Having looked more closely at your code and error messages, it's clear that I was looking in the wrong area. Some searching turned up a bug in wpf.

The short version: the windir environment variable may be set incorrectly on the target machine, which causes the font subsytem to break. The workaround is to fix the environment variable, either on the target machine's registry, or in the code by adding something like the following to the startup:

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