How to reload a form

I have looking for the solution but still found nothing
Here is my code:
private void Form1_Load(object sender, EventArgs e)
{
RichTextBox rtb = new RichTextBox();
rtb.Text = File.ReadAllText(#"C:\Users\Admin\Desktop\myfile\customers.txt");
int i = 0;
foreach (string line in rtb.Lines)
{
if (line == "--")
{
ListViewItem item = new ListViewItem();
item.Text = rtb.Lines[i + 1];
item.SubItems.Add(rtb.Lines[i + 2]);
item.SubItems.Add(rtb.Lines[i + 3]);
item.SubItems.Add(rtb.Lines[i + 4]);
listView1.Items.Add(item);
}
i += 1;
}
}
private void button1_Click(object sender, EventArgs e)
{
Form2 pop = new Form2();
pop.ShowDialog();
string name = pop.name;
int age = int.Parse(pop.Age);
string dob = pop.DateOfBirth;
string addr = pop.Address;
StreamWriter write = new StreamWriter(#"C:\Users\Admin\Desktop\myfile\customers.txt",true);
write.Write("--\n");
write.Write("{0}\n",name);
write.Write("{0}\n",dob);
write.Write("{0}\n",age);
write.Write("{0}\n",addr);
write.Close();
}
The question is how do I reload the list view after I write the data into the text file?

Extract the logic out of Form1_Load
private void Form1_Load(object sender, EventArgs e)
{
RefreshListView();
}
private void button1_Click(object sender, EventArgs e)
{
Form2 pop = new Form2();
pop.ShowDialog();
string name = pop.name;
int age = int.Parse(pop.Age);
string dob = pop.DateOfBirth;
string addr = pop.Address;
StreamWriter write = new StreamWriter(#"C:\Users\Admin\Desktop\myfile\customers.txt",true);
write.Write("--\n");
write.Write("{0}\n",name);
write.Write("{0}\n",dob);
write.Write("{0}\n",age);
write.Write("{0}\n",addr);
write.Close();
RefreshListView();
}
private void RefreshListView()
{
listView1.Items.Clear();
RichTextBox rtb = new RichTextBox();
rtb.Text = File.ReadAllText(#"C:\Users\Admin\Desktop\myfile\customers.txt");
int i = 0;
foreach (string line in rtb.Lines)
{
if (line == "--")
{
ListViewItem item = new ListViewItem();
item.Text = rtb.Lines[i + 1];
item.SubItems.Add(rtb.Lines[i + 2]);
item.SubItems.Add(rtb.Lines[i + 3]);
item.SubItems.Add(rtb.Lines[i + 4]);
listView1.Items.Add(item);
}
i += 1;
}
}

How do I input a calculation into MessageBox in C#

I am trying to calculate the "change" due at the end of my program into a MessageBox. The Dollar amount entered into a text box needs to have the total subtracted from it but I just can't seem to see what I am doing wrong. Can anyone help me finish this?
namespace HardwareStore
{
public partial class frmMain : Form
{
public frmMain()
{
InitializeComponent();
ProductBox.Items.Add(new Hardware() { ItemNo = 1010, ProdName = "Hammer ", Price = (decimal)14.99d });
ProductBox.Items.Add(new Hardware() { ItemNo = 1056, ProdName = "Bag of Nails ", Price = (decimal)19.99d });
ProductBox.Items.Add(new Hardware() { ItemNo = 2001, ProdName = "Saw ", Price = (decimal)29.99d });
ProductBox.Items.Add(new Hardware() { ItemNo = 2005, ProdName = "Chainsaw ", Price = (decimal)69.99d });
ProductBox.Items.Add(new Hardware() { ItemNo = 3090, ProdName = "Ladder ", Price = (decimal)109.99d });
}
private void frmMain_Load(object sender, EventArgs e)
{
}
private void btnAddItem_Click(object sender, EventArgs e)
{
try
{
for (int i = 0; i < int.Parse(txtQuantity.Text); i++)
ReceiptBox.Items.Add(ProductBox.Items[ProductBox.SelectedIndex]);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void ReceiptBox_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void btnCalculate_Click(object sender, EventArgs e)
{
decimal subTotal = ReceiptBox.Items.Cast<Hardware>().Sum(item => item.Price);
decimal tax = Math.Round((subTotal * .075M), 2);
decimal total = subTotal + tax;
lblSub.Text = "$" + subTotal.ToString();
lblTax.Text = "$" + tax.ToString();
lblTotal.Text = "$" + total.ToString();
lblSub.Visible = true;
lblTax.Visible = true;
lblTotal.Visible = true;
}
private void btnChange_Click(object sender, EventArgs e)
{
MessageBox.Show("Change Due: $ ");
}
}
}

I think I caught it twice...
decimal total = 0; //declare the total as global variable
private void btnCalculate_Click(object sender, EventArgs e)
{
decimal subTotal = ReceiptBox.Items.Cast<Hardware>().Sum(item => item.Price);
decimal tax = Math.Round((subTotal * .075M), 2);
total = subTotal + tax;
lblSub.Text = "$" + subTotal.ToString();
lblTax.Text = "$" + tax.ToString();
lblTotal.Text = "$" + total.ToString();
lblSub.Visible = true;
lblTax.Visible = true;
lblTotal.Visible = true;
}
private void btnChange_Click(object sender, EventArgs e)
{
decimal customerPay = 100;
if (total != 0){
decimal changeDue = customerPay - total;
txtDollar.Txt = "$ " + changeDue.toString();
MessageBox.Show("Change Due: " + txtDollar.Txt);
}
}

Change you variables to doubles:
double count = 0, total = 0;
When you do this calculation:
int i = ((count / total) * 100);
You're currently doing integer arithmetic. The result of count / total (i.e 1 / 10 or 4 / 10) is rounded to 0. When you divide that by 100, the result is still 0, so your ProgressBar won't move.
Using the double type will correctly store the fractional part of your quotient.

The problem had already been pointed out by Grant Winney: It's the integer division.
Without changing data types of count and/or total you could use this:
int i = (int)((100.0 * count) / total)
or that:
int i = (100 * count) / total
where the former makes 100.0 * count a double and the division by total as well. The latter sticks to integer operations by simply multiplying count first (changing sequence of operations), such that the division will not be 0 as long as count is not 0.

pBar.Step = 2;
pBar.PerformStep();

When I click the button it adds £3.00 to the total on top of what is correct [closed]

The program is for a pizza menu, the button I click to add the pizza adds £3.00 on top of the actual total, I have looked for errors but can not find the problem. The program is not fully finished, only the adding of the pizza total is complete but something is wrong with the code which I can not find.
I also would like any suggestion to make the program more efficient.

Your code is fairly confusing, particularly because of controls with names like radioButton1, radioButton2, etc...
It looks like your issue could be stemming from the fact that when your pizza type radio buttons change state, you add the price of the newly selected pizza to the pizza price instead of replacing it.
I would strongly encourage you to adopt an object-oriented approach in your application. If you create a Pizza class with fields for extra toppings, each Pizza that you add to an order will know everything that should be on it and how much it costs in total, and the Pizza could have a .ToString() overload that would build the summary text you're looking for: i.e., "Supreme pizza (4.50) : cheese (.50), crispy onions (.50) = Total: 5.50"
Separating your business objects from the UI elements (checkboxes, radio buttons, text fields) will vastly simplify what you're trying to do.

This is a guess but your add button only sets all your check boxes.Checked = false and then displays a popup. It never actually adds the price of the current pizza selected to any totals.

how to convert from double with decimal point number to binary in c# visual studio

When converting a number with a decimal point from decimal to binary, this is what you do: first you take the part before the decimal point and convert it (in the usual way) to binary; and the part after the decimal point you multiply by 2 and see if it is >= 1; if it is not, write 0 and keep multiplying. You are done when it is = 1.00. For example:
2.25 -
You take the 0.25;
0.25 * 2 = 0.50 --> 0,
0.50 * 2 = 1.00 --> 1, and you just read the numbers.
So, 0.25 would be 0.01 (2.25 would be 10.01 binary.)
