Create a Map that gives you path in between source and destination



Introduction 

The following tutorial guides you through the process of showing path on Google Map using Html and JavaScript 



Use <div> tag with “id” attribute in <body> tag.

<div id="dvMap" >

Use following function in <script> tag.

<script type="text/javascript">

function myMap() {
  var mapCanvas = document.getElementById("dvMap");
  var mapOptions = {
    center: new google.maps.LatLng(51.508742,-0.120850),
    zoom: 5
  };
var map = new google.maps.Map(mapCanvas, mapOptions);
}
</script>

And call it in <body> Like:    <body onLoad="myMap()">. This give you google map after page load.


Use three <input> tag with “id” attribute to enter source and destination values and one to use as a button

 <input id="start" type="textbox/>
<input id="end" type="textbox" />
<input type="button" value="Direction" >

And add one more function in <script> to calculate route and to show you the path.
function calcRoute() {
            var latlng = new google.maps.LatLng(23.219104, 72.657137);
            var myOptions = {
                zoom: 15,
                center: latlng,
                mapTypeId: google.maps.MapTypeId.SATELLITE
            };

            var directionsDisplay = new google.maps.DirectionsRenderer();
            directionsDisplay.setPanel(document.getElementById("directionsPanel"));
            var map = new google.maps.Map(document.getElementById("dvMap"), myOptions);
            directionsDisplay.setMap(map);
            var directionsService = new google.maps.DirectionsService();
            var start = document.getElementById("start").value;
            var end = document.getElementById("end").value;

            var request = {
                origin: start,
                destination: end,
                travelMode: google.maps.DirectionsTravelMode.DRIVING
            };
            directionsService.route(request, function (result, status) {
                if (status == google.maps.DirectionsStatus.OK) {
                    directionsDisplay.setDirections(result);
                }
            });
        }

Call this function in onClick attribute in <intput type=” button”>..
That’s it. Run the code and enjoy it..

Create Shuffle Game in asp.net with c#.



Introduction:
I created this game in asp.net with c#. Basic knowledge is enough to create this application you do not need to have advance knowledge.



Create new Project in visual studio and add 16 buttons on form and arrange them in 4*4 matrix form  and it will looks like..



Add bellow shuffle method on form.cs file
public void Shuffle()
        {
            int i,j,RN;
            int []a = new int[16];
            Boolean flag = false;
            i = 1;
           
            do
            {
                Random rnd = new Random();
               
                RN = Convert.ToInt32((rnd.Next(0,15)) + 1);
                for (j = 1; j <= i; j++)
                {
                    if (a[j] == RN)
                    {
                        flag = true;
                        break;
                    }
                   
                }
                if (flag == true)
                {
                    flag = false;
                }
                    else
                {
                    a[i] = RN;
                    i = i + 1;
                }
            }
            while (i <= 15);
            button1.Text =Convert.ToString(a[1]);
            button2.Text = Convert.ToString(a[2]);
            button3.Text = Convert.ToString(a[3]);
            button4.Text = Convert.ToString(a[4]);
            button5.Text = Convert.ToString(a[5]);
            button6.Text = Convert.ToString(a[6]);
            button7.Text = Convert.ToString(a[7]);
            button8.Text = Convert.ToString(a[8]);
            button9.Text = Convert.ToString(a[9]);
            button10.Text = Convert.ToString(a[10]);
            button11.Text = Convert.ToString(a[11]);
            button12.Text = Convert.ToString(a[12]);
            button13.Text = Convert.ToString(a[13]);
            button14.Text = Convert.ToString(a[14]);
            button15.Text = Convert.ToString(a[15]);
            button16.Text = "";
            count = 0;
        }

And call this Shuffle() method in form_load() Method to get shuffled buttons after project run.

private void Form1_Load(object sender, EventArgs e)
{
    Shuffle();
}

Add two more methods to switch numbers and check the numbers if they are in series or not.

public void CheckButton(Button bttn1, Button bttn2)
{
     if (bttn2.Text == "")
     {
         bttn2.Text = bttn1.Text;
         bttn1.Text = "";
     }

}
public void CheckSolved()
{
    count = count + 1;
    label2.Text = count + " Clicks";
    if (button1.Text == "1" && button2.Text == "2" && button3.Text == "3" && button4.Text == "4" && button5.Text == "5" && button6.Text == "6" && button7.Text == "7" && button8.Text == "8" && button9.Text == "9" && button10.Text == "10" && button11.Text == "11" && button12.Text == "12" && button13.Text == "13" && button14.Text == "14" && button15.Text == "15" && button16.Text == "")
     {
          MessageBox.Show("WOW YOU DID IT IN " + count + " CLICKs");
     }
           
}

Double clicks on every button to create buttons_Click() Method. Call CheckButton() and CheckSolved() methods in every buttons_Click() Method. Pass two parameters in CheckButton() method first will be current button id and next will be nearest button id and call same method for add nearest ids. Use same process for every buttons. And they will looks like..

private void button1_Click(object sender, EventArgs e)
        {
            //Button 2,5
            CheckButton(button1, button2);
            CheckButton(button1, button5);
            CheckSolved();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            //1,3,6
            CheckButton(button2, button1);
            CheckButton(button2, button3);
            CheckButton(button2, button6);
            CheckSolved();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            //2,4,7
            CheckButton(button3, button2);
            CheckButton(button3, button4);
            CheckButton(button3, button7);
            CheckSolved();
        }

        private void button4_Click(object sender, EventArgs e)
        {
            //3,8
            CheckButton(button4, button3);
            CheckButton(button4, button8);
            CheckSolved();
        }

        private void button5_Click(object sender, EventArgs e)
        {
            //1,6,9
            CheckButton(button5, button1);
            CheckButton(button5, button9);
            CheckButton(button5, button6);
            CheckSolved();
        }

        private void button6_Click(object sender, EventArgs e)
        {
            //2/5/10/7
            CheckButton(button6, button2);
            CheckButton(button6, button5);
            CheckButton(button6, button7);
            CheckButton(button6, button10);
            CheckSolved();
        }

        private void button7_Click(object sender, EventArgs e)
        {
            //3/6/11/8
            CheckButton(button7, button3);
            CheckButton(button7, button8);
            CheckButton(button7, button11);
            CheckButton(button7, button6);
            CheckSolved();
        }

        private void button8_Click(object sender, EventArgs e)
        {
            //4..12,7
            CheckButton(button8, button12);
            CheckButton(button8, button4);
            CheckButton(button8, button7);
            CheckSolved();
        }

        private void button9_Click(object sender, EventArgs e)
        {
            //5,10,13
            CheckButton(button9, button10);
            CheckButton(button9, button13);
            CheckButton(button9, button5);
            CheckSolved();
        }

        private void button10_Click(object sender, EventArgs e)
        {
            //6,9,11,14
            CheckButton(button10, button11);
            CheckButton(button10, button9);
            CheckButton(button10, button6);
            CheckButton(button10, button14);
            CheckSolved();
        }

        private void button11_Click(object sender, EventArgs e)
        {
            //7,10,15,12
            CheckButton(button11, button10);
            CheckButton(button11, button12);
            CheckButton(button11, button15);
            CheckButton(button11, button7);
            CheckSolved();

        }

        private void button12_Click(object sender, EventArgs e)
        {
            //8,11,16
            CheckButton(button12, button11);
            CheckButton(button12, button16);
            CheckButton(button12, button8);
            CheckSolved();
        }

        private void button13_Click(object sender, EventArgs e)
        {
            CheckButton(button13, button14);
            CheckButton(button13, button9);
            CheckSolved();
        }

        private void button14_Click(object sender, EventArgs e)
        {
            CheckButton(button14, button10);
            CheckButton(button14, button13);
            CheckButton(button14, button15);
            CheckSolved();
        }
