Hi all,
I try the following scenario:
- a C++ library (my own code), unmanaged, makes use of boost (e.g. regex) - a C++ .NET application (windows forms based) planned as GUI (having used Borland C++ builder in the past, the windows forms approach looks quite appealing to me)
- my C++ library header is included in the .Net form header file wrapped in a #pragma unmanaged/managed pair.
I compiles and links well.
For simple test purposes, I instantiate a class from my C++ library in the form constructor. Calling some unmanaged code from my library there creates a debug assertion:
"Debug Assertion Failed! [...] Expression: _CrtIsValidHeapPointer(pUserData) Well, its a bit off topic, and I don't know exactly the cause of the assertion failure.
But, I have a different approach for you: I usually pack all my unmanaged/native C++ stuff in static libraries and link them into a managed C++ class library. By adding some managed C++ wrapping code, hiding all unmanaged stuff from the class libraries' interface, I'm even able to use such class libraries from C# or other CLR languages. I did this several times, with alot of boost on the unmanaged side.
