Insert and Fetch Image from Database Using .Net

In this Example I will show you how to insert and fetch Image Directly from Database.

Step 1. First We will create Table.




Step 2.
Now code to insert image in Database
SaveImage.aspx

Design.

<form id="form1" runat="server">
    <asp:FileUpload ID="FileUpload1" runat="server" />
    <asp:Button ID="Button1" runat="server"
        Text="Button" onclick="Button1_Click" />
</form>


Code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
public partial class saveimageinbinary : System.Web.UI.Page
{
    SqlConnection conn;
    string s = ConfigurationManager.ConnectionStrings["imageconverter"].ConnectionString.ToString();
    protected void Page_Load(object sender, EventArgs e)
    {
        conn = new SqlConnection(s);
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        StartUpLoad();
    }
    private void StartUpLoad()
    {

        //get the image file that was posted (binary format)

        byte[] theImage = new byte[FileUpload1.PostedFile.ContentLength];
        HttpPostedFile Image = FileUpload1.PostedFile;
        Image.InputStream.Read(theImage, 0, (int)FileUpload1.PostedFile.ContentLength);
        int length = theImage.Length; //get the length of the image
        string fileName = FileUpload1.FileName.ToString(); //get the file name of the posted image
        string type = FileUpload1.PostedFile.ContentType; //get the type of the posted image
        int size = FileUpload1.PostedFile.ContentLength; //get the size in bytes that
        if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "")
        {
            //Call the method to execute Insertion of data to the Database
            ExecuteInsert(theImage, fileName, length);
            Response.Write("Save Successfully!");
        }
    }

    private void ExecuteInsert(byte[] Image, string Name, int length)
    {
        
        string sql = "INSERT INTO TblImages (Image, ImageName) VALUES "
       + " (@img,@imgname)";

       // SqlCommand cmd = new SqlCommand(sql,conn);

       // conn.Open();
       //// cmd.ExecuteNonQuery();
       
        try
        {
            conn.Open();
            SqlCommand cmd = new SqlCommand(sql, conn);
            SqlParameter[] param = new SqlParameter[4];

            param[0] = new SqlParameter("@img", SqlDbType.Image, length);

            param[1] = new SqlParameter("@type", SqlDbType.NVarChar, 50);
            param[2] = new SqlParameter("@imgsize", SqlDbType.BigInt, 9999);
            param[3] = new SqlParameter("@imgname", SqlDbType.NVarChar, 50);

            param[0].Value = Image;

            param[1].Value = Type;
            param[2].Value = Size;
            param[3].Value = Name;

            for (int i = 0; i < param.Length; i++)

            {
                cmd.Parameters.Add(param[i]);
            }

            cmd.CommandType = CommandType.Text;

            cmd.ExecuteNonQuery();
        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "Insert Error:";
            msg += ex.Message;
            throw new Exception(msg);
        }
        finally
        {
        
            conn.Close();
        }
    }
}

Step 3
Fetch Image from Database.
Here I am using Handler.ashx page to retrieve image.
ShowImage.aspx


Design.


 <div>
 <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="true"             onselectedindexchanged="DropDownList1_SelectedIndexChanged">
        </asp:DropDownList><br />
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label><br />

Color Particular Cell of Gridview

In this Example i will use onRowDataBound property of Gridview to color particular cell.

Just we have call a function on "onRowDataBound" property 
Ex: onRowDataBound="Grid_rowColor"

.aspx Page
 
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="id"  OnRowDataBound="Grid_rowColor">
    <Columns>
    <asp:BoundField DataField="name" HeaderText="name" SortExpression="name" ReadOnly="true" />
    <asp:BoundField DataField="number" HeaderText="number" ReadOnly="true"  SortExpression="number" />

    </Columns>
</asp:GridView>

 <asp:SqlDataSource ID="SqlDataSource1" runat="server"
 ConnectionString="<%$ ConnectionStrings:testchatConnectionString %>"
  SelectCommand="SELECT [name], [number], [id] FROM [testdemo]">
  </asp:SqlDataSource>

.cs page
 public void Grid_rowColor(object sender, GridViewRowEventArgs e)
    {
    if(e.Row.RowType==DataControlRowType.DataRow)
    {
        int value1= Convert.ToInt32(e.Row.Cells[1].Text.ToString());
        if (value1 > 2 && value1 < 30)
        {
            for (int i = 0; i < e.Row.Cells.Count; i++)
            {
                e.Row.Cells[i].BackColor = System.Drawing.Color.Green;
            }
        }
        else if (value1 >= 30 && value1 <= 50)
        {
            for (int i = 0; i < e.Row.Cells.Count; i++)
            {
                e.Row.Cells[i].BackColor = System.Drawing.Color.Gray;
            }

        }
        else
        {
            for (int i = 0; i < e.Row.Cells.Count; i++)
            {
                e.Row.Cells[i].BackColor = System.Drawing.Color.Yellow;
            }
        }
      }
    }

LINQ to Object Examples

LINQ: Language Integrated Query


you’ll need to persist objects to a database, query the database and load the results back into objects. The problem is that in
most cases, at least with relational databases, there is a gap between your programming language and the database. Good attempts have been made to provide object-oriented databases, which would be closer to object-oriented platforms and imperative programming languages like C# and VB.NET. However, after all these years, relational databases are still pervasive and you still have to struggle with data-access and persistence in all of your programs.The original motivation behind LINQ was to address the impedance mismatch between programming languages and databases. With LINQ, Microsoft’s intention was to provide a solution for the problem of  object-relational mapping, as well as simplify the interaction between objects and data sources. 

LINQ eventually evolved into a general-purpose language-integrated querying toolset. This toolset can be used to
access data coming from in-memory objects (LINQ to Objects), databases (LINQ to SQL), XML documents (LINQ to XML), a file-system, or from any other source.

Examples


 Response.Write("<h2>LINQ to Object</h2>");

        int[] numbers = { 5,6,7,8,3,4,9,1,2,0 };

        var no= from n in numbers
                    group n by n % 2 into g 
                    select new { Reminder=g.Key ,Number=g   };
        foreach (var g in no)
        {
            string s = string.Format("<br/>no of remainder of {0} when divided by 2:", g.Reminder);
            Response.Write(s);
            
            foreach (var n in g.Number)
            {
                Response.Write("<br/>"+n);
            }
        }
        /*
     OUTPUT
      no of remainder of 1 when divided by 2:
     5
     7
     3
     9
     1
      no of remainder of 0 when divided by 2:
     6
     8
     4
     2
     0
        */
        // for word lenth
        Response.Write("<h3>find length of word</h3>");
  string[] word = { "ABCD","EFG","HIJKL","MN","OPQRST","UVWXYZ"};

        var len = from words in word

                 // where words.Length <= 5
                 orderby words.Length ascending
                  select words;
        foreach (var leng in len)
        {
            Response.Write("<br/>" + leng + " >>Length :" + leng.Length);
        }
              
          /*
           OUTPUT
        find length of word
        MN >>Length :2
        EFG >>Length :3
        ABCD >>Length :4
        HIJKL >>Length :5
        OPQRST >>Length :6
        UVWXYZ >>Length :6
           */
                      
        //find even no

        Response.Write("<h3>find even number</h3>");

        int[] number = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15 };

        var ev = from even in number
                 where even % 2 == 0
                 orderby even descending
                 select even;
        Response.Write("Even Number<br/>");
        foreach (var evn in ev)
        {
            Response.Write(evn+"<br/>");
        }

Split and Merge File Example in asp.net

In this example i am showing how to split the file size into more than one file.
(Example: suppose file size is of 200byte and i want to split this file into 2 part 100byte each and save them)

in .aspx page
 <asp:FileUpload ID="FileUpload1" runat="server" />
 <asp:Button ID="btnupload" runat="server" Text="find Byte"
          onclick="btnupload_Click" />
 </p>
 <p>
  No to split :
 <asp:TextBox ID="txtsayno" runat="server"></asp:TextBox>
 </p>
 <p>
 <asp:Button ID="btnsplit" runat="server" onclick="btnsplit_Click" Text="Split" />
 </p>
 
 
in .cs page

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
    FileInfo info;
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnupload_Click(object sender, EventArgs e)
    {
        if (FileUpload1.HasFile && FileUpload1.FileContent.Length > 0)
        { FileUpload1.PostedFile.SaveAs(

Server.MapPath("file/"+FileUpload1.FileName));
         info=new FileInfo(Server.MapPath("file/"+FileUpload1.FileName));
         Session["filename"] = "file/" + FileUpload1.FileName;
            long fileinByte=info.Length;
            Response.Write(fileinByte);
        }
    }
    protected void btnsplit_Click(object sender, EventArgs e)
    {
        flename = new string[100];
        string file = Server.MapPath(Session["filename"].ToString());
        info = new FileInfo(file);

        FileStream fs = new FileStream(file,FileMode.Open,FileAccess.Read);
       int no=Convert.ToInt32(txtsayno.Text);
        int size=Convert.ToInt32(info.Length / no);
        for (int i=0;i<no;i++)
        {
         
        string basename = Path.GetFileNameWithoutExtension(file);
        string ex = Path.GetExtension(file);
        Session["extension"] = ex;
        FileStream outputFile = new FileStream(Path.GetDirectoryName(file) + "\\" + basename + "." + i.ToString().PadLeft(5, Convert.ToChar("0")) + ex + ".tmp", FileMode.Create, FileAccess.Write);
       flename[i] = basename + "." + i.ToString().PadLeft(5, Convert.ToChar("0")) + ex + ".tmp";
       string mergeFolder = Path.GetDirectoryName(file);
                    int bytesRead = 0;
                    byte[] buffer = new byte[size];
                    if ((bytesRead = fs.Read(buffer, 0, size)) > 0)
                    {
                        outputFile.Write(buffer, 0, bytesRead);
                    }
                    outputFile.Close();
                }
                fs.Close();             
        }

    }

Client Callbacks Example in Asp.net

Client callbacks : Rather than posting back the entire page, your custom control can send a request to the server to get just the additional information it needs.

Example:                                                        On Click of Button show Alert box with text value.

 in .aspx page                                                             <script type="text/javascript">
        function ss() {
            var va = document.forms[0].Text1.value;
            UseCallback(va, "");
      
    
        }
        function show(Text1, context) {
            alert(Text1);
      
        }
    </script> 
      <asp:Panel ID="Panel2" runat="server">
      <input id="Text1" type="text" runat="server" />
      <input id="Button1" type="button" value="button" onclick="ss()"/>
        </asp:Panel>

   in .cs page                              
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
  
 public partial class _Default: System.Web.UI.Page, System.Web.UI.ICallbackEventHandler
{
  protected void Page_Load(object sender, EventArgs e)
    {
        string cref = Page.ClientScript.GetCallbackEventReference(this, "arg", "show", "context");
        string cscript = "function UseCallback(arg,context)" +
            "{" + cref + ";" + "}";
        Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "UseCallback", cscript, true);
    } 
  public string GetCallbackResult()
    {
        return aa;
    }
    public void RaiseCallbackEvent(string eventArgument)
    {
        aa = eventArgument;

Built and Play Piano using Asp.net

In this blog I am showing the example of Making piano.
"Built and play piano using keyboard and mouse"


We can play piano only in client side. On server side this code will not be helpful.
Because i am using "winmm.dll" file for making sound which is located in client computer.


The script will check the keypress event by knowing their ASCII value.
in .aspx

<head runat="server">
    <title></title>
    <script type="text/javascript">


        document.onkeyup = KeyCheck;


        function KeyCheck(e) {
            var KeyID = (window.event) ? event.keyCode : e.keyCode;
            {
                __doPostBack('__Page', KeyID);
