catch (Exception ex)

MessageBox.Show(ex.Message + "\n\n" +
ex.GetType().ToString() + "\n" +
ex.StackTrace, "Exception");
}
}
}
That last '}' there closes your class statement. Don't think you wanted to do that yet.

I fixed that now it gives me 3 identifier error instances at the end of say public bool IsWithinRange(TextBox textBox, string name)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace Project_9_2
{
public partial class FrmReservations : Form
{
public FrmReservations()
{
InitializeComponent();
}
private void FrmReservations_Load(object sender, EventArgs e)
{
DateTime currentDate = DateTime.Today;
txtArrivalDate.Text = currentDate.ToString("d");
txtDepartureDate.Text = currentDate.AddDays(3).ToString("d");
}
private void btnCalculate_Click(object sender, EventArgs e)
{
try
{
if (IsValidData())
{
DateTime currentDate = DateTime.Today;
DateTime arrivalDate = DateTime.Parse(txtArrivalDate.Text);
DateTime departureDate = DateTime.Parse(txtDepartureDate.Text);
TimeSpan ts = departureDate.Subtract(arrivalDate);
int numNights = ts.Days;
decimal totalPrice = numNights * 115;
txtArrivalDate.Text = arrivalDate.ToShortDateString();
txtDepartureDate.Text = departureDate.ToShortDateString();
txtNumNights.Text = numNights.ToString();
txtTotalPrice.Text = totalPrice.ToString("c");
txtArrivalDate.Focus();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + "\n\n" +
ex.GetType().ToString() + "\n" +
ex.StackTrace, "Exception");
}
}
public bool IsValidData()
{
return
//Validate that arrival and departure dates are on or after current date.
IsValidDate(txtArrivalDate, "Arrival Date") &&
IsWithinRange(txtArrivalDate, "Arrival Date")&&
//Validate that departure date is after arrival date
IsValidDate(txtDepartureDate, "Departure Date");
}
public bool IsValidDate(TextBox textBox, string name, currentDate)
{
if (textBox.Text < currentDate)
{
MessageBox.Show(name + " must be later than today, must enter current date or later.", "Entry Error");
textBox.Focus();
return false;
}
return true;
}
public bool IsWithinRange(TextBox textBox, string name, arrivalDate, currentDate)
{
if (arrivalDate > currentDate.AddYears(5))
{
MessageBox.Show(name + " must be within 5 years", "Entry Error");
textBox.Focus();
return false;
}
return true;
}
private void btnExit_Click(object sender, EventArgs e)

this.Close();

I tried to fix your code, but there is so many things that need to be changed, so I advise you to rethink the logic and rewrite this form. Use DateTimePickers for choosing your date instead of parsing the text from your ArrivateDate & DepartureDate textboxes.

OK, this is just a partially fixed solution, although there are still lines of code that would need rewriting...
If you need any additional information about the code, feel free to ask...

Thank you for your help. I hate that I am so lost on this, my instructor is virtually non existent. I made some corrections on my code, but still am lost as to where to go from there. We don't have anything in our book about the DateTimePicker,
