Creating A Xml Document Using XML DOM And PHP

I had many issues to dealing with while solving this problem i i though about sharing this. The code below illustates a simple logis to create a XML file if it is not present and create a root node. And looking at this node you can create chile nodes.

The code is as follows:-

<?php
$uvar = "HELLO";
$doc = new DOMDocument('1.0', 'UTF-8');
$ele = $doc->createElement( 'root' );
$ele->nodeValue = $uvar;
$doc->appendChild( $ele );
$test = $doc->save("file.xml")

?>

This will create a file.xml with the following contents:-

<?xml version="1.0" encoding="UTF-8"?>
<root>HELLO</root>

Oracle and VB 6.0 Connectivity (Part 1)

Here is a basic VB application called voter information system demonstrated which explains the concepts quite clearly. The first step required to establish connectivity is preparing the back end and the front end of the project. These steps are divided into two parts first the back end that is the oracle and front end that is the Visual Basic 6.0. Oracle Firstly we need to set up the database. Create the tables, triggers and procedures and database in the oracle. Create tables: Example: create table voter(id number(5) primary key, name varchar2(25),address varchar2(50),age number(3),gender varchar2(6),dob varchar2(30)); create table votertemp(id number(5) primary key, name varchar2(25),address varchar2(50),age number(3),gender varchar2(6),dob varchar2(30)); (we will be using the next table in the triggers that we will be implementing) Visual Basic 6.0 Develop the VB application as in this example given below. Design the necessary forms for the application. The next part is ...

Validations in Visual Basic 6.0

This topic will demonstrate how to perform client side validations in Visual Basic 6.0. It will guide you with a step by step procedure. 1) Firstly in the below image suppose you want to accept only integer numbers as id in the textbox next to ID label in the form from the user you can perform client side validations in the following way: These are the ascii codes that i am using for acepting only integer values from user. Back space - 8 0 to 9 Integers - 48 to 57 Delete - 127 This is how the function will look. Private Sub Text2_KeyPress(KeyAscii As Integer) If Not ((KeyAscii >= 48 And KeyAscii <= 57) Or KeyAscii = 127 Or KeyAscii = 8) Then MsgBox "enter proper value" KeyAscii = 0 End If End Sub Double click on the text box which you want to validate. Next select the event as keypress from top right list box. In this case the name of text box is text1. This is the function for accepting input as integer value only from the user. ...

Oracle and VB 6.0 Connectivity (Part 3)

Now we will see how to insert values into table a table and to view them. Oracle Initially we had created table in part1. Visual Basic 6.0 Now we wil insert data into the table through visual basic. The code for inserting will be as follows When you double click on add button it will open your code window it will have this code! Private Sub Command1_Click() Dim gen As String If (Option1.Value = True) Then gen = "male" ElseIf (Option2.Value = True) Then gen = "female" End If rsv.Open "insert into voter values(" & Text5.Text & ",'" & Text2.Text & "','" & Text3.Text & "','" & Combo1.Text & "','" & gen & "','" & DTPicker1.Value & "')", conv, adOpenDynamic, adLockOptimistic If (rsv.State = 1) Then rsv.Close End If MsgBox ("Data Entered") End Sub This will add the data entered into...
