you need to define a public variable for checking the users, each time the user click on button and the information are wrong then add this variable
for date you can use datetimepicker then you do not need to check it out because your user should choose from the valid date just you can set the limitation for range of dates to be shown in that.
for age you can use the following code
int counter;
private void button1_Click(object sender, EventArgs e)
{
if (counter < 3)
{
try
{
if (textBox1.Text.Trim() == "")
{
MessageBox.Show("Please enter name");
return;
}
if (Convert.ToInt32(textBox2.Text) < 0 || Convert.ToInt32(textBox2.Text) > 99)
{
counter++;
MessageBox.Show("Please enter your age correctly");
return;
}
}
catch
{
counter++;
MessageBox.Show("Please enter your age correctly");
}
}
else
MessageBox.Show("sorry you cannot try more!");
}
private void Form2_Load(object sender, EventArgs e)
{
counter = 0;
}
