QueryInterface calls RRS feed

  • Question

  • If I write a COM component in VB.NET, is there any way for me to tell what interfaces I'm being queried for?

  • The IUnknown implementation exposed to any COM clients is actually provided by the CLR's marshaller, which means it won't show up in your code anywhere.  Unfortunately that means that there is no easy way to figure out what QI calls are being made against your component.
