insertion

问题 I am following a book ,Problem Solving & Program Design in C, to learn C. In this book, they gave all necessary parts to build a binary search tree.... But, My implementation didn't work. Here is insertion part; void add_to_t(tree_node_t *oldTreep, // input/output - binary search tree tree_element_t ele) // input - element to add { oldTreep = tree_insert(oldTreep, ele); } tree_node_t * tree_insert(tree_node_t *oldTreep, tree_element_t ele) { if(oldTreep == NULL){ oldTreep = TYPED_ALLOC(tree

问题 I am trying to develop a sample registration page using ASP.Net and C#. I am calling a stored procedure to insert the data to database. My database is SQL Server 2008. This is my code: public partial class Sample : System.Web.UI.Page { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ToString()); string str; protected void Page_Load(object sender, EventArgs e) { rbt_Male.Checked = true; } protected void btn_Submit_Click(object sender, EventArgs e) {

问题 Does hibernate preserve the order of a LinkedHashSet and if so, how? In case this depends on the type of database, I'd like to know this for PostgreSQL. Background: I know what a LinkedHashSet is for, and the reason I'm asking this is because I'm logging the names of some functions I execute to a 'logError' table that has a many-to-many relation to some 'functionName' table. I need these functions to remain in the same order as when I executed them, so first I find the corresponding

问题 Anyone who follows Android tags are probably familiar with me. I am having the hardest time implementing a SQLite database for my highscores. This is also my first time working with SQLite. I am trying to insert just two variables -- int and long. My insert() method is not working correctly. Any advice other than the stuff talked about above is also appreciated. Thank you in advance for your help. Highscores.java public class Highscores extends Activity { DatabaseHelper dh; SQLiteDatabase db;

问题 I'm trying to implement QAbstractItemModel for QTreeView. I have problem with inserting rows. I noticed that if I insert at the beginning of my application all works fine. But If I insert rows later - after some other operations (like selections etc.) new items stay invisible. Moreover QTreeView seems to doesn't work at all! Do I have to emit some signals to notify QTreeView about rows insertion? This is my insertion method: bool LayersModel::insertRows(int position, int count, const

问题 When we do dynamic insertion for javascript, sometimes order matters. We sometimes solve this by using onload property; however, if there are many external javascripts, and those scripts has to be loaded in order, then what should we do? I solved this problem by recursively defined onload functions; however not so sure about efficiency... since this is a script, I think it does lazy eval.... Any help? //recursively create external javascript loading chain //cautiously add url list according

问题 In simple terms, part of the project I'm working on has me taking an array that is descending in order and adding an element so that it the array remains in order. Initially I thought it would be simple just to add the element into the array and then sort after implementing Comparable, but then found out that sorting algorithms of any kind are prohibited; Collections as well. Kind of out of ideas on how to proceed from here, any hints? EX: int[] x = [ 7, 6, 6, 5, 3, 2, 1 ] add 4 [ 7, 6, 6, 5,

问题 I'm having an issue with inserting an entry into a Map. #include <stdio.h> #include <vector> #include <stack> #include <map> using namespace std; class Nodo { public: vector<Nodo> Relaciones; int Valor; bool Visitado; Nodo(int V) { Valor = V; Visitado = false; } }; class Grafo { public: Nodo *Raiz; map<int, Nodo> Nodos; Grafo(int V) { Raiz = new Nodo(V); //Getting http://msdn.microsoft.com/en-us/library/s5b150wd(v=VS.100).aspx here Nodos.insert(pair<int, Nodo>(V, Raiz)); } }; 回答1: You have a

问题 It appears from the :help while documentation that : NOTE: The ":append" and ":insert" commands don't work properly inside a ":while" and ":for" loop. And I can confirm they don't. But what should I use then to insert text from inside a loop? 回答1: The :insert and :append commands are mostly meant for interactive use. In a Vimscript, you can instead use the lower-level setline() and append() functions, which do work well in a loop. (They are also easier to use, because you can directly pass a

问题 I can't find where is the problem at my code. It only send single orders to the database. When I order in my cart 2 or more than items, it only sends the last order. I don't have any idea how I can change or add some syntax in my code. Here is my code in checkout.php <?php session_start(); echo '<h3>Your Order</h3>'; $current_url = base64_encode($url='http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); if(isset($_SESSION['products'])){ echo '<ol>'; echo '<form action="checkout_with_us
