Adding item to CTreectrl C++
<p>I have a requirement of converting a project from VB to C++.</p>

<p>There is Tree control in VB.
For adding items to Tree control "Add" Method(Nodes Collection)
has been used, which contains a parameter called "key" and the same key can be retrieved on click of that particular item.</p>

<p>Is there any such provision in CTreeCtrl InsertItem function using TVITEM or TVITEMEX structure where we can add a key to each item of the tree control and get it back when clicked on it?</p>
