Windows Form Application

Hi All,

In my project, I have a native class and a managed class. If I need to create something like NativeClass native[size] in the managed class, how can I do it?

If I did something like what I had done above, I will get error C4368: cannot define 'native' as a member of managed 'Project::ManagedClass': mixed types are not supported

I am using Visual Studio C++ 2005.

There's managed code and then there's unmanaged code. You can't mix these.

You will need to research interoperability for a solution.

Sorry but I am still quite new to using Windows Form. Can I ask what do you mean by interoperability?

Any help is appreciated. Thanks.

Interoperability is the name Microsoft gives to the steps you have to follow to move from managed to unmanaged code and vice versa.

Just look up the word in MSDN.
