Let us create an application that will allow 2 forms of user inputs : First textbox takes in the user name as a string , while second textbox takes in the user date of birth, the retreive button should output the result from both first textbox and second textbox.
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
nameTextBox.Text = "Your name pls"; // default input execute only when page load
birthdayTextBox.Text = "m/d/yyyy"; // default input execute only when page load
}
}
protected void okButton_Click(object sender, EventArgs e)
{
resultLabel.Text = "";
// name textbox takes a default value
// Default value should be clear off once a postback occur as to output user input
//Birthday textbox accept user input check if today is someones birthday or not.
DateTime now = DateTime.Now;
string dow =now.Day.ToString();
int dow1 = int.Parse(dow);
string mon = now.Month.ToString();
int mon1 = int.Parse(mon);
string yearnow = now.Year.ToString();
DateTime birthday = DateTime.Parse(birthdayTextBox.Text);
string bow = birthday.Day.ToString();
int bow1 = int.Parse(bow);
string Month = birthday.Month.ToString();
int Month1 = int.Parse(Month);
string year = birthday.Year.ToString();
// string old = now.Subtract(birthday).ToString();
int convertyearnow = int.Parse(yearnow);
int convertyear = int.Parse(year);
int old = convertyearnow - convertyear;
string yourage = old.ToString();
string dayold = (old > 7) ? "days" : "day"; // checks if the person is just newly born
string suffix;
int[] suffix2 = new int[3] { 11, 12, 13 };// check the days order of positions
{
if (suffix2.Contains(old))
{
suffix = "th";
}
else if (old % 10 == 1)
{
suffix = "st";
}
else if (old % 10 == 2)
{
suffix = "nd";
}
else if (old % 10 == 3)
{
suffix = "rd";
}
else
{
suffix = "th";
}
}
if ( mon1 == Month1 && dow1 == bow1 && convertyear < convertyearnow)
{
resultLabel.Text = string.Format("Welcome {0} ,
Today {1},{2} is your birthday, Congratulations on your {3}{4} birthday.",
nameTextBox.Text, mon, dow, yourage,suffix);
Today {1},{2} is your birthday, Congratulations on your {3}{4} birthday.",
nameTextBox.Text, mon, dow, yourage,suffix);
else if (dow1 == bow1 && mon1 == Month1 && convertyear == convertyearnow)
{
resultLabel.Text = string.Format("Welcome {0}, Today {1},{2},{3} is your birthday and you are just {4} {5}", nameTextBox.Text, mon, dow, yearnow, yourage, dayold);
}
else if ( convertyear > convertyearnow)
{
resultLabel.Text = string.Format
("Oops your birthdate is greater than current,Today is {0}.
<br> Did you forget your calendar", now.ToShortDateString());
}
else
{
resultLabel.Text = string.Format("Welcome {0} ,
Today {1},{2},{3} is not your birthday ", nameTextBox.Text, mon, dow, yearnow);
}
// resultLabel1.Text = suffix;
}
}
}
1 .Application : Default load view
2. Application: Put date that is not same with the current date
3. Application: Put date that is greater than current date
4. Application: if input date is correct with date now, it then wishes you happy birthday
Note:
Throughout this app our code loads nameTextBox.Text = "Your name pls";and birthdayTextBox.Text = "m/d/yyyy"; only at the default load view and once a button is click after new user inputs has been typed in, PostBack occur, This grab and submit new inputs from users.
