You are trying to mix native C++ with managed C++/CLI, this is not allowed.

edit:
I can see that you are at least you are trying to use the native type via a pointer...

[Gor]

But how can i do like this, i want define a class 'point' and than define 'point p' in public ref class Form1?

[Gor]

And when i`m tring like this



point* p;

public:

Form1(void)
{
InitializeComponent();
//
//TODO: Add the constructor code here
//
p = new point();
}

there are errors like this.

Sorry, been a bit busy with work.

I have put your (original) code into a project and tried building it.
Didn't get the same error as you reported and it was just a matter of changing p = new point(); to p = new snake::point(); to get it to build.

if you are having error C4368, you may have some project settings wrong...let me just check something...

Edit:
No, I can't reproduce your error.
