How referencing object in Delphi

I'm hooked into Outlook Express. I can see Objects, I can have their ID, Handle and name but... I can use them because I can reference them.

HwndOE,[197484] is ancestor
  ToolbarWindow32,     ID[20],         Handle{132082} is one of children of HwndOE
    TTreeView,           ID[132068],     Handle{132068} is one of children of ToolbarWindow32

So my question is : How referencing object(like TTreeView) by handle ?  If I want to know the count of items.

Thanks for any help,

The treeview in Outlook Express is NOT compatible with the Delphi treeview. You could try to use the Treeview API's that are located in the Commctrl unit (TreeView_GetRoot(), TreeView_GetChild(), TreeView_GetFirstVisible(), etc...) but you will need the handle for the treeview in that case. (But you seem to have that handle.) Also keep in mind that you might be doing some cross-process actions so this could lead into minor problems.
