BOOL DeleteItem( HTREEITEM hItem );
Return Value
Nonzero if successful; otherwise 0.
Parameters
hItem
Handle of the tree item to be deleted. If hitem has the TVI_ROOT value, all items are deleted from the tree view control.
Remarks
Call this function to delete an item from the tree view control.
Example
// Gain a pointer to our tree control
CTreeCtrl* pCtrl = (CTreeCtrl*) GetDlgItem(IDC_TREE1);
ASSERT(pCtrl != NULL);
// Look at all of the root-level items
HTREEITEM hCurrent = pCtrl->GetNextItem(TVI_ROOT, TVGN_NEXT);
while (hCurrent != NULL)
{
// Get the text for the item. Notice we use TVIF_TEXT because
// we want to retrieve only the text, but also specify TVIF_HANDLE
// because we're getting the item by its handle.
TVITEM item;
TCHAR szText[1024];
item.hItem = hCurrent;
item.mask = TVIF_TEXT | TVIF_HANDLE;
item.pszText = szText;
item.cchTextMax = 1024;
BOOL bWorked = pCtrl->GetItem(&item);
// Try to get the next item
hCurrent = pCtrl->GetNextItem(hCurrent, TVGN_NEXT);
// If we successfuly retrieved an item, and the item's text
// contains a lowercase letter 'e', delete the item.
if (bWorked && _tcschr(item.pszText, 'e'))
pCtrl->DeleteItem(item.hItem);
