Phonebook for Shanti - 27/04

I made use of 3 forms for this question.

FORM 1:
The first form contains all the buttons for the Phonebook application.

The code for FORM 1 is as follows:


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 PhoneProgram
{
public partial class frmAddressBook : Form
{
public static int iCount = 0;
public static string[,] sName = { { "", "" }, { "", "" }, { "", "" }, { "", "" }, { "", "" }, { "", "" }, { "", "" }, { "", "" }, { "", "" }, { "", "" } };
public static string sFriendModify = "";

frmAddForm addForm = new frmAddForm();
Prompt promptForm = new Prompt();

public frmAddressBook()
{
  InitializeComponent();
}

private void btnAdd_Click(object sender, EventArgs e)
{
  addForm.ShowDialog();

  cmbName.Items.Clear();
  //add new items
  for (int i = 0; i < 10; i++)
  {
      if ((sName[i, 0] != "") || (sName[i, 0] != null))
      {
          //cmbName.Items.Add(sName[i,0]);
          cmbName.Items.Add(sName[i, 0].ToString());
      }
  }
}

private void btnFind_Click(object sender, EventArgs e)
{
  if (cmbName.Text != "")
  {
      for (int i = 0; i < 10; i++)
      {
          if (sName[i, 0] == cmbName.Text)
          {
              MessageBox.Show(sName[i, 0].ToString() + " has phone number " + sName[i, 1].ToString(), sName[i, 0].ToString() + " Information", MessageBoxButtons.OK, MessageBoxIcon.Information);

              return;
          }
      }

      //reached end of array for search
      {
          MessageBox.Show(cmbName.Text.ToString() + " was not found. ", cmbName.Text.ToString() + " Not Found", MessageBoxButtons.OK, MessageBoxIcon.Information);
      }

  }
  else
  {
      MessageBox.Show("No friend selected", "Select a Friend to find", MessageBoxButtons.OK, MessageBoxIcon.Error);
  }
}

private void btnCount_Click(object sender, EventArgs e)
{
  int iFriends = 0;
  for (int i = 0; i < 10; i++)
  {
      if (sName[i, 0] != "")//empty
      {
          ++iFriends;
      }
  }

  MessageBox.Show("You have " + iFriends + " friends in your Address Book.", iFriends.ToString() + " Friends Found", MessageBoxButtons.OK, MessageBoxIcon.Information);
}

private void btnModify_Click(object sender, EventArgs e)
{
  if (cmbName.Text == "")
  {
      MessageBox.Show("No friend selected", "No friend selected to modify", MessageBoxButtons.OK, MessageBoxIcon.Error);
      return;
  }
  else
  {
      //modify
      sFriendModify = cmbName.Text;
      promptForm.ShowDialog();
  }
}

private void btnDelete_Click(object sender, EventArgs e)
{
  if (cmbName.Text == "")
  {
      MessageBox.Show("No friend selected", "No friend selected to modify", MessageBoxButtons.OK, MessageBoxIcon.Error);
      return;
  }
  else
  {
      for (int i = 0; i < 10; i++)
      {
          if (cmbName.Text == sName[i, 0])
          {
              cmbName.Items.Remove(sName[i, 0].ToString());
              //perform delete 
              sName[i, 0] = "";
              sName[i, 1] = "";
              MessageBox.Show("Contact Details deleted", "Contact Details deleted", MessageBoxButtons.OK, MessageBoxIcon.Information);
              return;

          }
      }
  }
}
}
}

FORM 2:
The second form will enable the user to enter name and phone number in the Phonebook.

Code is as follows:


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;

          {
              if ((frmAddressBook.sName[i, 0] == "") || (frmAddressBook.sName[i, 0] == null)) //empty element
              {
                  frmAddressBook.sName[i, 0] = txtName.Text.Trim();
                  frmAddressBook.sName[i, 1] = txtPhone.Text.Trim();

                  txtName.Text = "";
                  txtPhone.Text = "";
                  MessageBox.Show("Friend added", "AddressBook Updated", MessageBoxButtons.OK, MessageBoxIcon.Information);

                  //update combobox


                  return;
              }
          }

          /* Array Full */
          MessageBox.Show("Address Book is Full", "Address Book Full", MessageBoxButtons.OK, MessageBoxIcon.Error);
      }
  }

  /***********************Function Lists *************************/
  private int fnValidate()
  {
      if (txtName.Text == "")
      {
          MessageBox.Show("Enter a Name", "Name missing", MessageBoxButtons.OK, MessageBoxIcon.Error);
          txtName.Focus();
          return -1;
      }


      if (txtPhone.Text != "")
      {
          try
          {
              int iPhoneNum = int.Parse(txtPhone.Text);
              if ((txtPhone.Text.Length > 10) || (txtPhone.Text.Length < 8))
              {
                  MessageBox.Show("Phone Number is not valid", "Invalid Phone Number", MessageBoxButtons.OK, MessageBoxIcon.Error);
                  txtPhone.SelectAll();
                  return -1;
              }
          }
          catch
          {
              MessageBox.Show("Phone Number is not valid", "Invalid Phone Number", MessageBoxButtons.OK, MessageBoxIcon.Error);
              txtPhone.SelectAll();

          txtPhone.Focus();
          return -1;
      }

  }
}
}

using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace PhoneProgram

          {
              int iPhoneNum = int.Parse(txtPhoneNum.Text);
              if ((txtPhoneNum.Text.Length > 10) || (txtPhoneNum.Text.Length < 8))
              {

              txtPhoneNum.SelectAll();
              return;
          }

          //modify phone number
    
          for (int i = 0; i < 10 ; i++)
          {
              if (frmAddressBook.sName[i, 0] == frmAddressBook.sFriendModify)
              {

                  frmAddressBook.sName[i, 1] = txtPhoneNum.ToString().Trim();

                  MessageBox.Show(frmAddressBook.sName[i, 0].ToString() + ", Phone Number is updated to " + txtPhoneNum.Text.ToString(), "Phone Number Updated", MessageBoxButtons.OK, MessageBoxIcon.Information);
                  Prompt.ActiveForm.Close();
              }
          }

      }
      else
      {
          MessageBox.Show("Enter a Phone Number", "Enter Phone Number", MessageBoxButtons.OK, MessageBoxIcon.Error);
          txtPhoneNum.Focus();
          return;
      }
  }

  private void btnCancel_Click(object sender, EventArgs e)
  {
      Prompt.ActiveForm.Close();
  }

  private void Prompt_Load(object sender, EventArgs e)

Pizza Hot!

Free publicity to the pizza house :)

Some interesting things I found while doing this:

1) Scroll bar required when the order list is too long
2) Window should resize on Adding a pizza to the order

Everything is in the code. It might be confusing so let me know if you need some help on that.

PS: I am using some methods/functions. They work like events, so I don't think you'll struggle with understanding that :)

Assignment due next week - Shanti's Travel Agency

I have uploaded my assignment on my website. It's nothing exceptional, pretty plain but straight to the point. Some plain javascript validations on the form.

http://denisk.webs.com/creative.html

Pages are XHTML & CSS1.2 compliant. What do you think?

C# Classwork - Allan - Book Seat

This question is taxing if you want to validate everything, like check if booking has already made, smoker/non smoker and the seat validation.

Another problem concerns the display of the seat arrangement, as shown in the picture.

Check it out for yourself...


private void btnBook_Click(object sender, EventArgs e)
{
try{
    int iSeatNo = 0;
    iSeatNo = int.Parse(txtSeat.Text);
    if (iSeatNo <= 10)
    {

    }
    else
    {
        MessageBox.Show("Seat Number not valid");
        txtSeat.Clear();
        txtSeat.Focus();
    }

    if ((iSeatNo <= 5) && (iSeatNo > 0) && (radSmoke.Checked == true))
    {
        if (book[iSeatNo - 1] == false)
        {
            book[iSeatNo - 1] = true;
            grpSmokingArea.Controls[iSeatNo-1].Text = "BOOKED";
            grpSmokingArea.Controls[iSeatNo-1].ForeColor = Color.Red;
            lblInfo.Text = "You have booked Seat # " + iSeatNo + " \nin the
            Smoking Area";
        }
        else
        {
            MessageBox.Show("Seat already taken");
        }
    }
    else if (radSmoke.Checked== true)
    {
        MessageBox.Show("Seat allowed in non-smoking section only");
        txtSeat.Clear();
        txtSeat.Focus();
        return;
    }

    /* Non Smoking */
    if ((iSeatNo > 5) && (iSeatNo <= 10) && (radNoSmoke.Checked == true))
    {
        if (book[iSeatNo - 1] == false)
        {
            book[iSeatNo - 1] = true;
            grpNonSmokingArea.Controls[iSeatNo - 6].Text = "BOOKED";
            grpNonSmokingArea.Controls[iSeatNo - 6].ForeColor = Color.Red;
            lblInfo.Text = "You have booked Seat # " + iSeatNo + " \nin the Non
