    Tree Views are quite tedious to use in VC++.

    I have quite a lot of experience with them. Where to begin...
    First off, to add a TV to the window/dialog.

    You have to have called InitCommonControlsEx with ICC_TREEVIEW_CLASSES specified.

    To draw the window use CreateWindowEx with WC_TREEVIEW as the class name.

    To add nodes to the tree...
    Each node has a set of properties, stored in a TVITEM structure.

    Each node has parents, siblings and children.
    The control itself has one parent of all the children. This can be retrieved by calling
    HTREEITEM ParentItem = TreeView_GetRoot(hCtrl);

    You can then use TreeView_GetItem(hCtrl, &tvitem);
    to retrieve the properties of each node, including the parent node.

    Calls such as TreeView_InsertItem and TreeView_SetItem are used to insert new items and set the properties of existing nodes.

    You can traverse through the tree view by using calls such as TreeView_GetNextSibling, TreeView_GetPrevSibling, TreeView_GetParent, TreeView_GetChild.

    I think that should be enough to get you started.

    If you have any more questions, just stick them up here.
