Huge error when declaring custom data type in a vector

[dillinger88]

HI, I'm relatively new to programming in C++. I'm pretty solid in C and Java though.

Anyway, I'm trying to create a class, Mesh, that has a vector full of my other class, Node, however the compiler doesn't seem to like it. I've looked through the console message but I don't have a clue where to start!

Here's the source code thus far:

Node.h:

#pragma once

ref class Node
{
	int x, y, z;
	bool isBoundary;
public:
	Node();
	Node(int, int, int);
	int getX(){return x;}
	int getY(){return y;}
	int getZ(){return z;}
};

Mesh.h:

#pragma once
#include "Node.h"
#include <vector>

ref class Mesh
{	
	int numOfNodes;
	
public:
	Mesh(void);
	Mesh(int);
	void createNode(int, int, int);
	Node getNode(int);
	std::vector<Node> meshNodes();
};

The error(s) I'm getting are:

Many thanks for looking!

Are you trying to compile it as a CLR application? (I noticed you added in the ref class keyword). If not, change your project type to Win32 console app, that will get you the standard C++ flavor.

[dillinger88]

Thank you for your reply.

I've checked the project properties and for platform I have Win32 selected. Is this what you meant?

The ref keyword was put there by the class builder, it's a result of having 'Managed' selected, I believe. Though I'm still unsure of what it does.

I apologise if this is a trivial matter, but it really does have me stumped.

[jonsca]

No need to apologize. Yeah, you don't want managed. Just to be safe, create a new project. In the dialog box that comes up go to Win32 Console application (not Win32). Deselect precompiled headers. Add your code back into the project by right clicking on the project name and using the Add..Existing Item... option in the Solution Explorer (or you might be better off creating a new (unmanaged) class--also under the Add...menu--and copying and pasting your information into it.

Tried it out this morning (GMT), and it worked perfectly.

Thanks a lot for the help!
