Hello  everybody. When I am trying to send an email with HTML format the values are coming from database i felt problem with godaddy server.

నేను ఒకసారి GoDaddy ద్వారా ఈమెయిలు పంపిస్తుంటే చాలా ప్రొబ్లెంస్ వచ్చాయి
నేను వాటిని పరిశోధించి చివరికి చిన్న సమాధానం కనుకునా ఏమైనా సందేహం వుంటే మెయిల్ చెయ్యండి

Email; radhek@gmail.com

To solve that we must add relay hosting.

I’d just like to add that when you’re sending email via “relay-hosting.secureserver.net” you will be able to send email via the GoDaddy server but it will not work if you run it locally. This is normal - it’s a security feature.

Code below

using system.net.mail namespace.

const string SERVER = “relay-hosting.secureserver.net”;

System.Net.Mail.MailMessage objMail = new System.Net.Mail.MailMessage();

objMail.From = new MailAddress(“”);objMail.To.Add(MailId);

objMail.Bcc.Add(BCC);

objMail.IsBodyHtml = true;

objMail.Subject = “Order Confirmation”;

objMail.Priority = System.Net.Mail.MailPriority.High;

objMail.Body = “<h1>hi</h1>”;

SmtpClient Client = new SmtpClient(SERVER);Client.Send(objMail);

U need to Specifie the SMTP CLIENT SERVER LIKE THAT

This is working with my Godaddy Server try out

How to know the width & height of an uploaded image in ASP.NET

ఇమేజ్ యొక్క పొడవు వెడల్పు in ASP.NET

Import the namespace using System.IO;
Step 1:
using System.IO;

Step 2:
System.Drawing.Image UploadedImage = System.Drawing.Image.FromStream(Image1.PostedFile.InputStream);
Here Image1 is the name of uploaded image.

System.Drawing.Image.FromStream
Creates an Image from the specified data stream.
To know more visit: http://msdn.microsoft.com/en-us/library/system.drawing.image.fromstream.aspx

Step 3:
Now you can get width and height of image using

UploadedImage.Width
UploadedImage.Height

Random number generation in ASP.NET

ఏదో ఒక్క నెంబర్ జనరేషన్ in ASP.NET

Step 1:

write a class file.
eg:

Create a cs file named as rand.cs

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Microsoft.VisualBasic;

/// <summary>
/// Summary description for random_number
/// </summary>
public class random_number
{
public string GetRandomNumber(int length, string characterSet)
{

string randomData = “”;

int position = 0;

byte[] data = new byte[length];

int characterSetLength = characterSet.Length;

System.Security.Cryptography.RandomNumberGenerator random = System.Security.Cryptography.RandomNumberGenerator.Create();

random.GetBytes(data);

for (int index = 0; (index < length); index++)
{

position = data[index];

position = (position % characterSetLength);

randomData = (randomData + characterSet.Substring(position, 1));

}

return randomData;

}

}

step 2:

use this in codebehind of any aspx page

random_number r1 = new random_number();
string str= r1.GetRandomNumber(5, “ABCDEFGHIJLLMNOPQRSTUVWXYZ_1234567890″);

BoundField in Grid view and bind the data to each field using “Edit Column” option in smarttag of grid view.

We can also add images to Edit and Delete option in Grid view “edit columns” by adding a “commandfield”.

String con1 = ConfigurationManager.ConnectionStrings["con"].ToString();

DataSet ds = new DataSet();

protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

{

GridView1.EditIndex = -1;

bindata();

}

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

string i = GridView1.DataKeys[e.RowIndex].Value.ToString();

int j = Convert.ToInt32(i);

TextBox t1 = new TextBox();

t1 = (TextBox)GridView1.Rows[e.RowIndex].Cells [0].Controls [0];

TextBox t2 = new TextBox();

t2 = (TextBox)GridView1.Rows[e.RowIndex].Cells [1].Controls [0];

TextBox t3 = new TextBox();

t3 = (TextBox)GridView1.Rows[e.RowIndex].Cells [2].Controls [0];

SqlConnection con = new SqlConnection(con1);

string upt = “update Allergies set Allergy = @allergy, Symptoms = @symptom, Action_to_be_taken =@action where Allergy_id=” + j;

SqlCommand cmd = new SqlCommand(upt, con);

cmd.Parameters.Add(“@allergy”, SqlDbType.VarChar).Value = t1.Text;

cmd.Parameters.Add(“@symptom”, SqlDbType.VarChar).Value = t2.Text;

cmd.Parameters.Add(“@action”, SqlDbType.VarChar).Value = t3.Text;

con.Open();

cmd.ExecuteNonQuery();

con.Close();

GridView1.EditIndex = -1;

bindata();

}

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)

{

GridView1.EditIndex = e.NewEditIndex;

bindata();

}

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)

{

string i = GridView1.DataKeys[e.RowIndex].Value.ToString();

int j = Convert.ToInt32(i);

SqlConnection con = new SqlConnection(con1);

string del = “Delete from Allergies where Allergy_id=” + j;

SqlCommand cmd = new SqlCommand(del, con);

con.Open();

cmd.ExecuteNonQuery();

con.Close();

GridView1.EditIndex = -1;

bindata();

}

in popup.aspx write down the following line

Response.Write(”<script>window.opener.location=’sample.aspx’;window.close();</script>”)

this will close popup after clicking save button of popup and refresh the parent form.

If you want to generate serial number column in data controls just see below:

Gridview: Container.DataItemIndex+1

(For e.g. In gridview

<asp:TemplateField HeaderText=”S.No”>
<ItemTemplate><%#Container.DataItemIndex+1 %></ItemTemplate>
</asp:TemplateField>

)
Datalist:  Container.ItemIndex+1
Formview: Container.PageIndex+1

Encrypted Querystring

Hello friends When we are passing data between two asp.net pages we will use querystring. But the original value will be displayed there which is not a secure way to do. So we must encrypt that information.

I faced the same situation and searched GOOGLE and come across a nice article by Mr.Tiberius OsBurn of DEVCITY. The original article you can get at: http://www.devcity.net/PrintArticle.aspx?ArticleID=47.

Basically I am C# guy. I made some changes to that program and its working fine now.

First we will write a class file where Encrypt and Decrypt functions will be there.By using them we will execute that.

1) Create a class file in APP_CODE folder and paste this code.

Code Begins

“

using System;
using System.IO;
using System.Xml;
using System.Text;
using System.Security.Cryptography;

public class Encryption64
{
private byte[] key = { };
private byte[] IV = { 18, 52, 86, 120, 144, 171, 205, 239 };

public string Decrypt(string stringToDecrypt, string sEncryptionKey)
{
byte[] inputByteArray = new byte[stringToDecrypt.Length + 1];
try
{

//key = System.Text.Encoding.UTF8.GetBytes(Left(SEncryptionKey, 8));
key = System.Text.Encoding.UTF8.GetBytes(sEncryptionKey.ToCharArray(), 0, 8);
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
inputByteArray = Convert.FromBase64String(stringToDecrypt);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateDecryptor(key, IV), CryptoStreamMode.Write);
cs.Write(inputByteArray, 0, inputByteArray.Length);
cs.FlushFinalBlock();
System.Text.Encoding encoding = System.Text.Encoding.UTF8;
return encoding.GetString(ms.ToArray());
}
catch (Exception e)
{
return e.Message;
}
}

public string Encrypt(string stringToEncrypt, string SEncryptionKey)
{

try
{
key = System.Text.Encoding.UTF8.GetBytes(SEncryptionKey.ToCharArray(), 0, 8);
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
byte[] inputByteArray = Encoding.UTF8.GetBytes(stringToEncrypt);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(key, IV), CryptoStreamMode.Write);
cs.Write(inputByteArray, 0, inputByteArray.Length);
cs.FlushFinalBlock();
return Convert.ToBase64String(ms.ToArray());
}
catch (Exception e)
{
return e.Message;
}
}

}

“

Code Ends

Take an aspx page and write the code and write the code below.

“

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Security.Cryptography;

public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
public string encryptQueryString(string strQueryString)
{
//ExtractAndSerialize.Encryption64 oES =
//    new ExtractAndSerialize.Encryption64();
Encryption64 oES = new Encryption64();
return oES.Encrypt(strQueryString, “!#$a54?3″);
}

public string decryptQueryString(string strQueryString)
{

Encryption64 oES = new Encryption64();
return oES.Decrypt(strQueryString, “!#$a54?3″);
}

protected void lnk_btn_Click(object sender, EventArgs e)
{
string strValues = “search”;
string strURL = “http://yoursite.com?search=”
+ encryptQueryString(strValues);

Response.Redirect(strURL);
}
}

“

In aspx

Take a link button with Id=”lnk_btn”.

when you click it will encrypt an you can decrypt by using the class file.

Bye

Hello When we have some 30 textboxes in a page where it has a master Page. If we want to erase all th data  in textboxes usuallywe will write TextBox1.Text==” “; But it s time consuming so I have the easy way to do it.    wait…….

“

private void getAllCtl(ControlCollection ctls)
{
foreach (Control c in ctls)
{
if (c is System.Web.UI.WebControls.TextBox)
{
TextBox txt = c as TextBox;
txt.Text = “”;

}
if (c.HasControls())
{
getAllCtl(c.Controls);

}
}
}

I must have written my last remotely technical post some months ago However, there is one 1995 experiment about which I read only today and about which I wanted to share with others…

A multi-lingual browser for WWW without pre-loaded fonts,  Akira Maeda, Takehisa Fujita, Lee Swee Choo, Tetsuo Sakaguchi, Shigeo Sugimoto, Koichi Tabata,In Proceedings of ISDL95, August 1995.

However, as I read through this very short paper today, I can’t resist myself from writing about it. The concept appears interesting for me, as it eliminates the need for pre-loaded fonts on the client system. If this becomes(or did it became?) commercial, I believe, the problems of display, font installation etc will not exist and there will be absolutely no difference in browsing English and non-English sites.

Their idea is simple. They have demonstrated a new prototype called MHTML (Multilingual HTML). Their browser converts a HTML document to MHTML document, which involves in determining the set of characters in the document, assign code to each character, extract a font glyph for each character and reproduce the font on the client side browser. They have also compared this approach with other font-less approaches like - Image mapping and Character to inline map. This approach proved to be a better performer.

Iam somehow very fascinated by this idea and would love to know more on what happened afterwards. God knows how I found this 1995 paper in 2008 and am still fantasizing about it I am clueless on “what happened next?”. Anyone…who chanced upon this post and knows about it…please drop a comment.
