In this code I will show you to make a simple splash screen with a progress bar and using httpwebrequest to report to the progressbar.

A zip file for download is attached for this project.

 This is the form1 code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using System.Threading;

namespace Splash_Screen_With_Progress_Bar
{

    public partial class Form1 : Form
    {
        private FileDownload fd;
        public static Splash_Screen splash_s;
        private string Link = "http://www.ims.gov.il/Ims/Pages/RadarImage.aspx?Row=9&TotalImages=10&LangID=1&Location=";
        private string FileName;

        public Form1()
        {
            InitializeComponent();

            splash_s = new Splash_Screen();
            fd = new FileDownload(this);
            FileName = @"c:\temp\test.jpg";

            fd.File_Download(Link, FileName);
            splash_s.Show();

            for (int i = 1; i < 100; i++)
            {
                Thread.Sleep(30);
                Application.DoEvents();
            }
            splash_s.SyncedClose();
            splash_s = null;
            FileDownloadCompleted();
        }

        public void FileDownloadCompleted()
        {
            label1.Text = "File Download Completed";
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
    }
}

 This is the code of the Splash screen form:

 

The Splash screen form i called it Splash_Screen_With_Progress_Bar

I added to the Splash form in the designer a background image then set the form size to 589,260 and the properties Start Position = center screen , Show in taskbar = false , Form Border Style = none ,  AutoScale Mod = font

 

Then I added a progressBar control to the form and set it's property Dock to Bottom.

The progressBar size is: 589,23
