I will start here - C# and .NET
How did you conclude that an OS-specific hardware group would be the best place to ask?
I'd try microsoft.public.dotnet.languages.csharp. Andrew "john" wrote in message ... I reviewed all the newgroup selections on this site and saw this as the closest possiblility. Question: I am trying to use P/Invoke to import DLLs and so far I have succeeded with many WIN32 APIs. However, I found a case that MSDN has not reference. I need to import a DLL function that contains OPTIONAL parameters and my case requires a NULL to be inserted, in the case with C++. However, I need to pass a "ref" in C# to hold to the Import format, and need to somehow pass a NULL to the parameter in C#. Any ideas? I reviewed all the MSDN P/Invoke literature from John Hind and Eric Gunnerson from Microsoft and they don't have any mention on this topic. Richard Grimes does not touch on the subject either. Any help or direction would be appreciated. |
