Question

我一直收到这个错误：

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.

但我的.xaml文件中没有COM组件。它不断弹出并说错误的位置是第1行第1列，我只有Window而没有别的：

    </DockPanel>

    <Window.TaskbarItemInfo>
        <TaskbarItemInfo x:Name="Display" />
    </Window.TaskbarItemInfo>

我甚至不断收到此错误：

System.NullReferenceException was unhandled by user code
  Message=Object reference not set to an instance of an object.

  StackTrace:

       at MS.Internal.Xaml.Runtime.ClrObjectRuntime.SetValue(Object inst, XamlMember property, Object value)

这就是我正在使用的：

private void TBMenubar1ShowButton_Checked(object sender, RoutedEventArgs e)
{
    TBMenu1.Visibility = System.Windows.Visibility.Visible;
    TBrowser.Properties.Settings.Default.Menubar = System.Windows.Visibility.Visible;
}

我不知道怎么回事。

Answer 1

我认为它是通过向需要32位INT的应用程序发送64位INT来解决的（如果是这个问题），请遵循以下步骤：

右键单击项目（在解决方案资源管理器中） - ＆gt;属性，构建选项卡，平台目标集x86。然后做一个Clean-Build并给它一个旋转。

这是什么错误：System.Runtime.InteropServices.COMException？
