Pointers and winforms?

[Natique]

Hi :) I'm using winforms to try to make a GUI on Visual C++ 2005. Now one of the forms deals with a linked list (what's supposed to happen is that when a customer clicks the sign up button, a new customer object is appended to the end of the list). The problem is I know how to make linked lists in normal c++ (umm... like not managed, sorry I'm really bad with the terminology), but for some reason I can't define pointers in the forms. So I can't make a linkedlist, and I have no clue how to get around it.

Example:

customers * first;

gives the error C3699: '*':cannot use the indirection on type 'Ethicsprojectfinal::customers'

So I did this

customers ^first;
first=0;

I get: error C2446 no conversion from 'int' to 'Ethicsprojectfinal::customers ^'
So obviously it's not a pointer, and it can't point at null. And I'm completely lost. I guess my question is is there a way to use pointers in forms? And if not, how do you make linked lists with forms?

Thanks a lot!

Forget about pointers here. Use a generic LinkedList object instead.
You don't know how it's implemented, but it has plenty of methods to feel confortable with. Pointers can still be used but in an unmanaged context.

Of course you can always make your own linked list cikara21 but if you are using VC++ why should you? When you can have this instead http://msdn.microsoft.com/en-us/library/he2s3bh7.aspx
