This project details and full source codes are available at www.arduinovb.net (maintained at separate server for php trial and error purpose)
we can read the data file stored in Server (with public access permission) and display in the RichTextBox
The Updated Items in code
Usual import libraries
Imports System.IO
Imports System.Text
Imports System.Net
I have added a textbox (TextBox1) to read the web address and a Command Button (CommandButton1) and Richtext box (RichTextBox2) to display the data
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim address As String
‘address = “http://www.example.com/trial-1.txt”
address = TextBox1.Text
If (address = “”) Then
Else
Dim client As WebClient = New WebClient()
Dim reply As String = client.DownloadString(address)
RichTextBox2.Text = reply
End If
End Sub
The data written in the text file (server)
Our OUTPUT (from the Version2.0)
ARDUINOVB.NET V2.0 PHP FUNCTIONS
PHP function used to write in to the text file from a web form is as shown below
<?php
function functiontrial1(){
?>
<form id=”form1″ method=”post” action=””>
<input name=”search1″ type=”search” autofocus>
<input type=”submit” formaction=”” name=”button1″>
</form>
<?php
if(isset($_POST[‘button1’]))
{ //trigger button click
$search=$_POST[‘search1’];
echo $search;
$myfile = fopen(“txtfiles/trial-1.txt”, “w”) or die(“Unable to open file!”);
fwrite($myfile, $search);
fclose($myfile);
}}
?>
Save this file as
trial-1.inc.php
and include in any php file where you need form like
include ‘trial-1.inc.php’;
in my case, it is the index.php file with login functionalities for trial purposes
<?php
require ‘core.inc.php’;
require ‘connect.inc.php’;
include ‘trial-1.inc.php’;
if(loggedin())
{
$name = getuserfield(‘name’);
echo ‘You are logged in ‘.$name.’ , <a href=”logout.php”>Log Out</a><br>’;
functiontrial1(); // write to text file form is available in this function
}
else
{
include ‘loginform.inc.php’;
}
?>
