I Have a Problem With Make A local Website That Can Be Accessed From other Computer in my Local Network
I want to Pass the image from picturebox and the text from textbox into the website.
I have used the code that I have found online but I have modified it.
Here Is My Code in the form:
using System.Text;
using System.Windows.Forms;
namespace Html_Server
{
public partial class Form1 : Form
{
private string TextToshpw;
Machine Machine;
public Form1()
{
InitializeComponent();
TextToshpw = textBox1.Text;
Machine = new Machine(555, TextToshpw);
}
private void button1_Click(object sender, EventArgs e)
{
// Machine.Update();
}
private void Form1_Load(object sender, EventArgs e)
{
Machine.Start();
}
}
}
And here is the code which I have found with modifications:
using System;
using System.Collections;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Threading;

But I Don't Know How To Pass The Image or how to update the server. Please advise.
