I have the registry displayed just like regedit in a TreeView

My Computer
    HKEY_CLASSES_ROOT
    HKEY_CURRENT_USER
    HKEY_LOCAL_MACHINE
    HKEY_USERS
    HKEY_CURRENT_CONFIG

I am trying to get the rootkeys of the parent and not the actual
root of the tree.  For example, if i select an item far below
HKEY_CURRENT_USER, i want it to return HKEY_CURRENT_USER
as the parent node, and not My Computer.

This is what i have.
void __fastcall TForm1::TreeView1Expanding(TObject *Sender,
      TTreeNode *Node, bool &AllowExpansion)
{
LPCSTR NameLBSelect = Node->Parent->Text.c_str();

Is there any way that i can get the parent on level 1, without going
to the actual root of the tree, i dont need the rootnode as the
parent.


Thanks in advance

Simply iterate the Parent hierarchy until you find a TreeNode that has its
Level property set to 1:

    void __fastcall TForm1::TreeView1Expanding(TObject *Sender, TTreeNode
*Node, bool &AllowExpansion)
    {
        if( Node->Level != 0 )
        {
            TTreeNode *ParentNode = Node;
            while( (ParentNode) && (ParentNode->Level > 1) )
                ParentNode = ParentNode->Parent;

            AnsiString NameLBSelect = ParentNode->Text;
            // ...
        }
    }
