Finding an item in a Tree Control

When I am adding second level entries, (the root levels are titles), to my tree view, I get duplicate entries in the Tree.
So I would like to be able to search through the existing tree items to find if there is a match. However, there is a bewildering array of GetxxxItem() - type functions, which one(s) should I use to do this??

Try the following
this assumes you are stroing an object pointer as the itemdata for an entry, if you are using text just compre the text instead

HTREEITEM OLITreeView::getTreeItemFor(yourObject * pyo, HTREEITEM item = GetRootItem())
{
HTREEITEM childItem, theItem;
YourObject *tpyo;
// Is the item null
if (item == NULL)
return NULL;

tpyo = (YourObject*)GetItemData(item);
// Is the item the one we want
if (tpyo == pyo)
return item;

if(!ItemHasChildren(item))
return NULL;

childItem = GetNextItem(item, TVGN_CHILD);
while (childItem != NULL)
{ // call this function recusivly to check all children
theItem = getTreeItemFor(pyo, childItem);
if (theItem !=NULL)
return theItem;
childItem = GetNextItem(childItem, TVGN_NEXT);
}
return NULL;
}

That worked really well, I refined the code a little as the item I am looking for will always occur in the first level below the root;

hLev1 = NULL; // Preset to no Level1 Entries
if (ctc.ItemHasChildren(hRoot)) // If there are any Level1 Entries
{
hLev1 = ctc.GetNextItem(hRoot, TVGN_CHILD); // Get the Level1 Handle
while (hLev1 != NULL)
{
cs = ctc.GetItemText(hLev1); // Get the Item Name
if (m_ArtName == cs) // If there is already a level1 for this Artist
break; // ..quit
else
hLev1 = ctc.GetNextItem(hLev1, TVGN_NEXT);// ..else get the next one
}
}
if (hLev1 == NULL) // If we found no matches
hLev1 = ctc.InsertItem(m_ArtName, hRoot, TVI_SORT); // Insert new entry into the tree
hLev2 = ctc.InsertItem(m_CDTitle, hLev1, TVI_SORT); // Add the Title Below

ctc.SetItemData(hLev2, m_CDKey); // ..and hide the key
