Excel加载项警告

Question

以下是我在创建此加载项时遇到的一些警告：

    Warning 1   
    Processing COM reference "" from path "C:\Windows\system32\stdole32.tlb". The type library importer could not convert the signature for the member 'DISPPARAMS.rgvarg'.

    Warning 2   
    Processing COM reference "" from path "C:\Windows\system32\stdole32.tlb". The type library importer could not convert the signature for the member 'DISPPARAMS.rgdispidNamedArgs'.

    Warning 3   
    Processing COM reference "VBA" from path "C:\Windows\system32\VEN2232.OLB". Type library importer has encountered an interface not derived from IUnknown: '_HiddenInterface'.

这个插件正常工作，但是我想知道这些警告是什么意思。当我看他们的时候，我看到的是，它有一些问题的processing COM references和converting一些文件从system32文件夹。我对此一无所知所以..。

有没有人可以看一看它们，给我一个更具体的解释，也许还有一些解决方案。我将非常感谢每一条信息。

这些错误没什么大不了的。它只是意味着COM类型库中的某些类型不能自动导入。从Visual Studio构建过程(或在后端使用的MSBuild任务)中，我不认为您可以删除这些错误。它们是由.NET内部类型库导入程序生成的，没有可以传递的标志。

但是，您可以在执行其他构建操作之前，使用Tlbimp.exe (Type Library Importer)工具创建所需的互操作程序集，并引用它们，而不是让集成开发环境来完成这项工作。该工具的最新版本支持silence开关。

不使用开关：

使用静音开关(多次出现)：
