Need help on basic binary tree programming

[DemonFox]

i found the caouse of problem it was the follow
int the tree.cpp i made the changes:
tree::tree(PTR t1)
{
PTR t;
t->data=t1->data;
t->left=t1->left;
t->right=t1->right;
}

and now it is ok
:P:P:P:P:P
but the next thing is:
void tree::preorder_ traversal(PTR t)
{
if(t!=NULL)
{
printf("%d",t->data);
preorder_traver sal(t->left);
preorder_traver sal(t->right);
}
}



How can i take the results of the function into a Edit??????
in optical interface?

I don't think I understand your requirement. Can you provide a little more info.

I have this
void tree::preorder_ traversal(PTR t)
{
if(t!=NULL)
{
printf("%d",t->data);
preorder_traver sal(t->left);
preorder_traver sal(t->right);
}
}

i want the results of the traversal
to be shown on an edit box.
the final think i want is to (give)insert a node to be presented in icons in a paintbox
to be shown step by step the traversals. did this help????

Are you using Windows?

If so there is a Tree control in MFC called CTreeCtrl. All the graphical work is done.
