Hi all, I'm stuck: I just can't get my head around how to access C# methods from C++. I've got as far as working out that you need a COM server, but none of the code I've tried works. Can anybody point me in the direction of a working project that demos how C++ can call methods from a C# library, using COM or otherwise? ...

I have followed the steps here to create a COM DLL in Visual Studio 2008. My objective is to wrap an existing unmanaged C++ .lib. Is there an easy way to implement the COM interface for the lib. Or do I just have to keep adding ATL simple objects which essentially wrap the objects in my library? For example, I have added the simple AT...

I'm responsible for maintaining legacy VB6 code, and have encountered an annoying problem with regard to the locking of a project's COM DLL. (We'll call it MyProject and MyProject.dll) When I load MyProject into the VB6 IDE, I am able to compile the resulting binary-compatible DLL MyProject.dll. I can then run my (Classic ASP) web appli...
We have a big body of code that was refactored so that stuff which was plain-old C++ is now COM. I've been spending the last couple of days hunting out places in which we missed the fact that a function that previously returned a bool now returns an HRESULT (the problem is compound by the fact that S_OK == false). Is there a way to det...
We build our setups with Wix. We have a mix of native and .NET components, and use COM for interop. Until now, I have used heat.exe to generate wix fragments for installing .NET assemblies and registering them as COM servers. The wix fragment created by heat takes care of writing the COM related registry entries. However, somebody just...
Compiling with Visual Studio 2005, on Windows XP. I add the following headers to my "stdafx.h" file like so: #include <atlbase.h> #include <atlcom.h> #include <atlcore.h> #include <atlstr.h> (technically the same error appears with just atlbase.h included) which produces the following errors: error C2334: unexpected token(s) precedi...
From what I understand, when a COM component marked as using STA is used from a MTA thread, the calls are supposed to be marshalled to an STA thread and executed from that dedicated thread. In the case of a Windows client application, this would mean that it would execute on the UI thread (if marked as STA), and that callbacks from the C...

I'm having trouble with a COM library I'm trying to use. I get an ArgumentException when I call a particular method and pass it null. This happens to me in both a C# project and a VB.NET project (I call the method using Nothing) where I added the library reference from the "COM" list in Visual Studio 2008. When I call this same method...
I'm writing Python 2.6 code that interfaces with NI TestStand 4.2 via COM in Windows. I want to make a "NAN" value for a variable, but if I pass it float('nan'), TestStand displays it as IND. Apparently TestStand distinguishes between floating point "IND" and "NAN" values. According to TestStand help: IND corresponds to Signaling NaN ...
