Creating website with .NET (And html & CSS)

Posted 13 March 2012 - 04:37 PM

I am trying to create a homepage.
Shortly, my problem is... I have added to images (left and right arrows) to my html page, and when a user clicks on one of these arrows, a GET method occurs (get the next photo, and show it on the htmlpage). I am trying to write the code that connects to the Mysql database, where I have created a table called Photos. The table has 3 columns: "id (int), picturename (varchar) and src (varchar)"
So I'm not saving my photos in the database, I only save references to the pictures. How do I go about with this?
Here is my html code:
      <a href="" class="leftArrow"><img id="venstrePil" style="position: relative; top: 350px; left: 0px" 
         src="smallLeftArrow.jpg" alt="" runat="server" /></a>  <!-- This is the left arrow the get's the previous pic -->

      <div class="innerDiv">  
         <img ID="midPic" class="billede" src="" alt="" runat="server"/>  <!--This is where the picture should be shown-->

Here is the C# code that connects to the database:
 protected void uploadPic()
        MySqlConnection connection = new MySqlConnection("SERVER=server;PORT=port; DATABASE=database; UID=userId;
        MySqlCommand command = connection.CreateCommand();
        command.CommandText = "SELECT * from Billeder ORDER BY id";

        Uri tempUri = new Uri("http://www.ExampleUri.com");
        String query = tempUri.Query;
        String resName = HttpUtility.ParseQueryString(query).Get("imgnr");     

        catch (Exception e)

        MySqlDataReader reader = command.ExecuteReader();
        while (reader.Read())
            midPic.Src = ???? I'm stuck here. Notice that midPic is the ID from the html code.


I'm pretty lost, so any help is greatly appreciated.
For those who have not understood my problem yet, here is the code that shows the exact concept that I want to do. It is just expressed in php code (I didnt write this code, someone else did it to show me the overall idea). I am not familiar with PhP, but I do understand most of the code below, since I've programmed java a lot (I know these 2 languages are not comparable).

		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
$conn = mysql_connect("mysql.domain.net", "domain_net", "password");
mysql_select_db("domain_net_db", $conn);
$imgnr = $_GET['imgnr'];
if ( !ctype_digit($imgnr) ) $imgnr = 0;
$cnt_billeder = mysql_result(mysql_query("SELECT COUNT( * ) FROM Billeder"), 0);
$get_billeder = mysql_query("SELECT * FROM Billeder ORDER BY id ASC LIMIT ".$imgnr.",1");
$go_billeder = mysql_fetch_array($get_billeder);
echo "<img style=\"width: 100px; \" src=\"images/".$go_billeder['src']."\" alt=\"".$go_billeder['billednavn']."\"/>" . "<br />";

$previmg = ($imgnr == 0) ? $cnt_billeder - 1 : $imgnr - 1;
$nextimg = ($imgnr + 1) % $cnt_billeder;

echo "<a href=\"?imgnr=" . $previmg . "\">Forrige</a>";
echo "<a href=\"?imgnr=" . $nextimg . "\">Nęste</a>";


Thanks alot
