Internet Information Services is used to make your computer a web server. If we want to have a web server for developing dynamic website or want to publish
website on our own server then we install the IIS.Internet Information Server (IIS) is a World Wide Web server, a Gopher server and an FTP server all rolled
into one. IIS means that you can publish WWW pages.
If you want to your web application accessible to any other pc in intranet or internet you need to IIS.

Below are steps for deployment:
1.Right click your website and click on Publish website.All compiles files are ready for deployment.
2.Create a backup for database whichever you are using and restore it on production server.
3.Go to server using ftp or filezila copy all compiles file on server.
4.Open Webconfig and change the connection string according to your Database name and server.
5.Create a virtual directory for this website.
6.Your website is ready.
7.Test website http://192.163.0.234(ServerName)/VDName/Login.aspx

Resize image in ASP.NET

In this example i am going to describe how to resize image in ASP.NET before/and upload to ms sql database using C# and Vb.NET.

For this i am using FileUpload control to upload the image in datbase after resizing.
I am also displaying the Image in Gridviw after uploading to database.

 public partial class _Default : System.Web.UI.Page   
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnUpload_Click(object sender, EventArgs e)
{
string strImageName = txtName.Text.ToString();
if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "")
{
string strExtension = System.IO.Path.GetExtension(FileUpload1.FileName);
if ((strExtension.ToUpper() == ".JPG") | (strExtension.ToUpper() == ".GIF"))
{
// Resize Image Before Uploading to DataBase
System.Drawing.Image imageToBeResized = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream);
int imageHeight = imageToBeResized.Height;
int imageWidth = imageToBeResized.Width;
int maxHeight = 240;
int maxWidth = 320;
imageHeight = (imageHeight * maxWidth) / imageWidth;
imageWidth = maxWidth;
if (imageHeight > maxHeight)
{
imageWidth = (imageWidth * maxHeight) / imageHeight;
imageHeight = maxHeight;
}
Bitmap bitmap = new Bitmap(imageToBeResized, imageWidth, imageHeight);
System.IO.MemoryStream stream = new MemoryStream();
bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
stream.Position = 0;
byte[] image = new byte[stream.Length + 1];
stream.Read(image, 0, image.Length);
// Create SQL Connection
SqlConnection con = new SqlConnection();
con.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
// Create SQL Command
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "INSERT INTO Images(ImageName,Image) VALUES (@ImageName,@Image)";
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
SqlParameter ImageName = new SqlParameter("@ImageName", SqlDbType.VarChar, 50);
ImageName.Value = strImageName.ToString();
cmd.Parameters.Add(ImageName);
SqlParameter UploadedImage = new SqlParameter("@Image", SqlDbType.Image, image.Length);
UploadedImage.Value = image;
cmd.Parameters.Add(UploadedImage);
con.Open();
int result = cmd.ExecuteNonQuery();
con.Close();
if (result > 0)
lblMessage.Text = "File Uploaded";
GridView1.DataBind();
}
}
}
}

ViewState And Session example

Hi,

View state is used for store data at page level,you cant access View state data to another page.
Session state is used for store data and you can access anywhere in your website.
Session state is state specific information per client basis.

Example is given below.

View State:
 protected void btnSubmit_Click(object sender, EventArgs e)  
{
ViewState["DataScorceName"] = datasource;
ViewState["ClientName"] = txtCustomer.Text;
}
//Retrieve viewstate information
txtCname.Text = ViewState["ClientName"]
Store information in Session State:
Session["EmpName"] = txtUser.Text;
//Retrieve session value in 2nd page
lblEmp.Text = Session["UserName"].ToString();


Thanks & Regards

DataReader

A DataReader is a read-only forward-only way of reading data. It is quiet fast when compared to fetching data using a DataSet.
Some important point:
Read-only access
Supports a single table based on a single SQL query of one database
Connected mode
Bind to a single control
Forward-only scanning of data
Faster access to data
Lightweight object with very little overhead
Must be manually coded

Code Sample:
SqlConnection myconn = new SqlConnection(connString);
SqlCommand mycomm = new SqlCommand("select * from emp", myconn);
mycomm.Connection.Open();
SqlDataReader dr =
mycomm.ExecuteReader(CommandBehavior.CloseConnection);
while(dr.Read())
{
Console.WriteLined(r.GetString(0));
}
dr.Close();
myconn.Close();

Authentication And Authorization

Authentication And Authorization
Authentication is the process of identification and validation of a user's credentials. After the identity is authenticated,
a process called authorization determines whether that identity has access to a particular resource.
ASP.NET provides three ways to authenticate a user:
Forms authentication
Windows authentication
Passport authentication

Setting in web.config file given below

Forms authentication
<configuration>
<system.web>
<authentication mode="Forms"/>
<forms name="login"loginUrl="loginPage.aspx" />
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</configuration>

Windows authentication
<authentication mode="Windows"/>
<authorization>
<allow users ="*" />
</authorization>

Passport authentication
<configuration>
<system.web>
<authenticationmode="Passport">
<passportredirectUrl="loginPage.aspx" />
</authentication>
<authorization>
<deny users="?" />
</authorization>
</system.web>
</configuration>

When Gridview has no record display empty grid at runtime

When GridView(Add New Record) has no record display empty Grid at runtime.
Some time when we adding new row in gridview footer column and there is no record in database,so what we can do?
So we can disply message no record found and add new button show for adding new record.
Here is solution display runtime empty gridview.
 private void ShowNoResultFound(DataSet ds,GridView gv)
{
DataTable dt = (DataTable)ds.Tables[0];
dt.Rows.Add(dt.NewRow());
gv.DataSource = dt;
gv.DataBind();
int TotalColumns = gv.Rows[0].Cells.Count;
gv.Rows[0].Cells.Clear();
gv.Rows[0].Cells.Add(new TableCell());
gv.Rows[0].Height = 0;
gv.Rows[0].Visible = false;
}

Session object in asp.net

Session object:

Session object is used to store state specific information per client basis. It is specific to particular user.
Session data persists for the duration of user session you can store session's data on web server in different ways.
Session state can be configured using the section in the application's web.config file.

Session state in ASP.NET can be configured in different ways based on various parameters including scalability, maintainability and availability

1.In process mode (in-memory)- State information is stored in memory of web server
2.Out-of-process mode- session state is held in a process called aspnet_state.exe that runs as a windows service.
3.Database mode – session state is maintained on a SQL Server database.

In process mode:
This mode is useful for small applications which can be hosted on a single server. This model is most common and default method to store session specific information. Session data is stored in memory of local web server

Configuration information:



Advantages:
Fastest mode
Simple configuration

Disadvantages:
Session data will be lost if the worker process or application domain recycles
Not ideal for web gardens and web farms

Out-of-process Session mode (state server mode):

This mode is ideal for scalable and highly available applications. Session state is held in a process called aspnet_state.exe that runs as a windows service
which listens on TCP port 42424 by default. You can invoke state service using services MMC snap-in or by running following net command from command line.

Net start aspnet_state

Configuration information:



Advantages:
Supports web farm and web garden configuration
Session data is persisted across application domain recycles. This is achieved by using separate worker process for maintaining state
Disadvantages:
Out-of-process mode provides slower access compared to In process
Requires serializing data

SQL-Backed Session state:
ASP.NET sessions can also be stored in a SQL Server database. Storing sessions in SQL Server offers resilience that can serve sessions to a large web farm that
persists across IIS restarts.
SQL based Session state is configured with aspnet_regsql.exe. This utility is located in .NET Framework's installed directory
C:\\microsoft.net\framework\. Running this utility will create a database which will manage the session state.

Configuration Information:


Advantages:
Supports web farm and web garden configuration
Session state is persisted across application domain recycles and even IIS restarts when session is maintained on different server.

Disadvantages:
Requires serialization of objects



Mode:
This setting supports three options. They are InProc, SQLServer, and State Server

Cookie less:
This setting takes a Boolean value of either true or false to indicate whether the Session is a cookie less one.

Timeout:
This indicates the Session timeout vale in minutes. This is the duration for which a user's session is active. Note that the session timeout is a sliding value;
Default session timeout value is 20 minutes

SqlConnectionString:
This identifies the database connection string that names the database used for mode SQLServer.

Server:
In the out-of-process mode State Server, it names the server that is running the required Windows NT service: aspnet_state.

Port:
This identifies the port number that corresponds to the server setting for mode State Server. Note that a port is an unsigned integer that uniquely identifies
a process running over a network.

You can disable session for a page using EnableSessionState attribute. You can set off session for entire application by setting mode=off in web.config file
to reduce overhead for the entire application.
