Hi all,
I want to insert new item into SECTreeCtrl. The tree is not empty already, and  new item must be first in the tree.
Does anybody know the answer ?

static HTREEITEM InsertTreeItem(SECTreeCtrl* ctrl,LPCTSTR txt,int imgind,int selimgind)
{
     TV_INSERTSTRUCT  TreeCtrlItem;      

     TreeCtrlItem.hParent = TVI_ROOT;
     TreeCtrlItem.hInsertAfter = TVI_LAST; //HERE
     TreeCtrlItem.item.mask = TVIF_IMAGE | TVIF_PARAM | TVIF_SELECTEDIMAGE | TVIF_TEXT;

     TreeCtrlItem.item.iImage = imgind;
     TreeCtrlItem.item.iSelectedImage = selimgind;
     TreeCtrlItem.item.lParam = 0;
     TreeCtrlItem.item.pszText = (LPTSTR)txt;
     
     HTREEITEM hTreeItem = ctrl->InsertItem(&TreeCtrlItem);
     return(hTreeItem);
}

Yep,
I use Objective Toolkit,
I solved the problem in an ugly way. I got parent and checked if it wasn't leaf, i gave an exceptional threatment.
10x all for trying
