TreeView删除节点没反映

Question

case WM_NOTIFY:
     {
     if(IDC_TRV1==wParam)
     {
     NMHDR* phdr = (NMHDR*)lParam;
     if(phdr->code == NM_DBLCLK)
            {
                HWND hTree = GetDlgItem(hwnd, IDC_TRV1);
                TCHAR str[256] = {0 };
                TVITEM item = { 0 };
                item.mask = TVIF_TEXT;
                item.cchTextMax = 256;
                item.pszText = str;
                item.hItem = TreeView_GetSelection(hTree);
                TreeView_GetItem(hTree, &item);
                MessageBox(hwnd,str,str,0);
                TreeView_DeleteItem(hTree,&item);
                
            } 
     }
    
     }break;到MessageBox都可以，最后删除节点为什么没反应呢，点的是根结点

Answer 1

TreeView_DeleteItem(hTree,item.hItem);
