我不断收到此错误：什么是这个错误：System.Runtime.InteropServices.COMException？
System.Runtime.InteropServices.COMException was thrown on "C:\Users\---\documents\visual studio 2010\Projects\TBrowser\TBrowser\TBrowserWindow.xaml": Error HRESULT E_FAIL has been returned from a call to a COM component.
但是我没有在我的.xaml文件COM组件。它不断弹出，说错误的位置是1号线1列，我只是有一个Window那里，没有别的：

这是什么即时通讯使用：
private void TBMenubar1ShowButton_Checked(object sender, RoutedEventArgs e)
{
TBMenu1.Visibility = System.Windows.Visibility.Visible;
TBrowser.Properties.Settings.Default.Menubar = System.Windows.Visibility.Visible;
}
而我不知道发生了什么事情。
我要猜你在Visual Studio中得到这个错误，你尝试运行这个项目，甚至之前。 VS大量使用COM。该错误非常不具描述性，但通常是由VS安装问题或注册表损坏引起的。 – 2012-01-02 17:24:58
不，我使用的是Visual C＃Express 2010. – thakyZ 2012-01-02 17:52:20
