如何在VB .NET程序中使用AfxOleGetMessageFilter？

We have a program that calls a long-running (SolidWorks) API function. After a while, we get an error dialog saying that "the COM server is busy...". We've done some research and have found that you can control this by using a bit of C++ code similar to:

我们有一个程序可以调用长期运行的(SolidWorks)API函数。过了一会儿,我们得到一个错误对话框,说“COM服务器正忙......”。我们做了一些研究,发现你可以通过使用类似于以下的C ++代码来控制它:

  COleMessageFilter *pFilter = AfxOleGetMessageFilter();
          if(pFilter)
          {
              pFilter->SetMessagePendingDelay(60000);
              pFilter = NULL;
          }

Problem is, we're ignorant on the C++ front and want to use VB.NET. We dug around and it turns out AfxOleGetMessageFilter comes from some MFC library. So my question is: is there some way we can achieve this call from VB.NET w/o getting into MFC? Is AfxOleGetMessageFilter a wrapper around some other WIN32API call that we can just DECLARE and call ourselves? Are there alternatives we should be pursuing?

问题是,我们在C ++方面一无所知,并且想要使用VB.NET。我们挖了一下,结果发现AfxOleGetMessageFilter来自一些MFC库。所以我的问题是:有没有什么方法可以从VB.NET实现这个调用进入MFC? AfxOleGetMessageFilter是一个包装其他WIN32API调用的包装器,我们可以直接DECLARE并调用自己吗?有没有我们应该追求的替代方案?

I have one answer that suggests I implement the .NET IMessageFilter interface, but since that interface has only one seemingly unrelated method I'm still stumped.

我有一个答案表明我实现了.NET IMessageFilter接口,但由于该接口只有一个看似无关的方法,我仍然难倒。

You can't reuse COleMessageFilter from MFC this way.

您不能以这种方式从MFC重用COleMessageFilter。

You have to implement IMessageFilter in VB.Net

您必须在VB.Net中实现IMessageFilter
