ASP.NET 5 Hosting France - HostForLIFE.eu :: Develop a Captcha Image Generator in ASP.NET

December 19, 2014 05:38 by author

Peter

In this tutorial, I will explain you how to Develop a Captcha Image Generator in ASP.NET 5 with C# or VB.NET. CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart". And here is the code that I use to generate take one .aspx page as GenerateCaptcha.aspx :

GenerateCaptcha.aspx.cs:
using System.IO;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Drawing.Imaging;
public partial class GenerateCaptcha : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Clear();
        int height = 40;
        int width = 110;
        Bitmap bmp = new Bitmap(width, height);
        RectangleF rectf = new RectangleF(12, 6, 0, 0);
        Graphics g = Graphics.FromImage(bmp);
        g.Clear(Color.White);
        g.SmoothingMode = SmoothingMode.AntiAlias;
        g.InterpolationMode = InterpolationMode.HighQualityBicubic;
        g.PixelOffsetMode = PixelOffsetMode.HighQuality;
        g.DrawString(Session["captcha"].ToString(), new Font("Cambria", 13, FontStyle.Bold), Brushes.Red, rectf);
        g.DrawRectangle(new Pen(Color.Green), 1, 1, width - 15, height -10);
        g.Flush();
        Response.ContentType = "image/jpeg";
        bmp.Save(Response.OutputStream, ImageFormat.Jpeg);
        g.Dispose();
        bmp.Dispose();
    }
}

Take .aspx where you want to use captcha.
UseCaptcha.aspx
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Create your own captcha image generator in ASP.NET using C#.NET/VB.NET</title>

<body>
    <form id="form1" runat="server">

        <asp:UpdatePanel ID="UpdatePanel1" runat="server">

                            <asp:Image ID="imgCaptcha" runat="server" />
                        </td>
                        <td valign="middle">
                            <asp:Button ID="btnRefresh" runat="server" Text="Refresh" OnClick="btnRefresh_Click" />
                        </td>
                    </tr>
                </table>
            </ContentTemplate>
        </asp:UpdatePanel>
        Enter Captcha:
        <asp:TextBox ID="txtCaptcha" runat="server"></asp:TextBox><br />
        <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />
    </div>
    </form>
</body>
</html>

UseCaptcha.aspx.cs
using System.Text;
using System.Drawing.Imaging;
public partial class UseCaptcha : System.Web.UI.Page
{
   protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            FillCaptcha();
        }
    }
    void FillCaptcha()
    {
try
Random random = new Random();
string combination = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
StringBuilder captcha = new StringBuilder();
for (int i = 0; i < 6; i++)
captcha.Append(combination[random.Next(combination.Length)]);
Session["captcha"] = captcha.ToString();
imgCaptcha.ImageUrl = "GenerateCaptcha.aspx";
}
catch
{
throw;
}
}
protected void btnRefresh_Click(object sender, EventArgs e)
{
FillCaptcha();
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
if (Session["captcha"].ToString() != txtCaptcha.Text)
Response.Write("Enter Valid Captcha Code");
FillCaptcha();
}
}

And this is the result from the code:

WordPress said it also invalidates links in a password reset email if the user remembers our password and logs in and changes our email address.

WordPress 4.0.1 addresses an additional eight security issues, including three other XSS vulnerabilities that can be exploited by a contributor or an author, a cross-site request forgery (CSRF) that can be leveraged to trick a user into changing his/her password, and a denial-of-service (DoS) bug.

ASP.NET 5 Hosting Italy - HostForLIFE.eu :: Using ValidationSummary Control in ASP.NET

December 15, 2014 06:01 by author

Peter

Today, I will show you how to ValidationSummary Control in ASP.NET 5. ValidationSummary control allow us to display summary of all validation errors. We can display validation errors summary inline of a web page or a message box or both by using ShowMessageBox and ShowSummary property value true or false.

ValidationSummary will display validation messages as bulleted list, 1 paragraph or only list based on DisplayMode. we can set a header text for validation summar. ASP.NET validationsummary control have many properties to design the error messages text as like fore color, back color, border color, border style, border width, theme, skin and after all CSS class.

This ValidationSummary, allow to summarize of all validation error messages from all validators in a single location. This code below will show you how can we display all validation error messages as summary using ValidationSummary control. In this example, I used three text box and make them required field using requiredfieldvalidator control. When user submit form without entering textboxes value, they got a validation error messages summary in one location as bulleted list.

And here is the example ValidationSummaryExample.aspx code:
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

December 5, 2014 06:53 by author

Peter

In this article, we want to talk about How to to develop a simple Example of text box control with ASP.NET 5. Once we enter data during this text box control we want to the length (re-size height and width) of text box. Text box is an ASP.NET web control, use for obtaining input by user as similar to the login web site we see username and password Textbox exactly in which we enter username and password. Inside the Toolbox we obtain a textbox only drag and drop it on ASP.NET web site and then it is automatically create our html code. We think about a text box and attempt to Auto re-size it once we enter value in text box.

And this is the example code that I used:
JavaScript function for resize ASP.NET control
And here is the Text Box auto resize function.

function resizemultilineTextBox(txt) {
            txt.style.height = "1px";
            txt.style.height = (1 + txt.scrollHeight) + "px";
        }
Asp.net web page code with Textbox:

ASP.NET 5 Hosting - HostForLIFE.eu :: How to create “Remember Me” Login Page using checkbox with ASP.NET ?

December 1, 2014 06:12 by author

Peter

In this tutorial, I will tell you How to create “Remember Me” Login Page using checkbox with ASP.NET 5 and C#. Whenever you tick Remember Me checkbox it will maintain username and password for web site user using Cookies.

When user click login button that could stores the username and password inside the cookie. First thing you need to do is confirm that the Remember Me checkbox is checked or not, if it's checked then store the username and password inside the cookie to the 1 month and if not checked then set the expiration day to 1 day in else condition to destroy the cookie.

And here is the code that I used:

protected void Page_Load(object sender, EventArgs e)
{
      if (!Page.IsPostBack)
      {
           if (Request.Cookies["UserName"] != null)
                txtUserName.Text = Request.Cookies["UserName"].Value;
           if (Request.Cookies["Password"] != null)
                txtPassword.Text = Request.Cookies["Password"].Value;
           if (Request.Cookies["UserName"] != null && Request.Cookies["Password"] != null)
                chkRember.Checked = true;
      }
}
protected void btnLogin_Click(object sender, EventArgs e)
{
       string stringconnection = ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString;
       MySqlConnection connection = new MySqlConnection(stringconnection);
      try
      {
           int flag = 0;
           if (chkRember.Checked == true)
           {
                Response.Cookies["UserName"].Value = txtUserName.Text;
                Response.Cookies["Password"].Value = txtPassword.Text;
                Response.Cookies["UserName"].Expires = DateTime.Now.AddMonths(1);
                Response.Cookies["Password"].Expires = DateTime.Now.AddMonths(1);
           }
           else
           {
                Response.Cookies["UserName"].Expires = DateTime.Now.AddMonths(-1);
                Response.Cookies["Password"].Expires = DateTime.Now.AddMonths(-1);
           }
           MySqlCommand com = new MySqlCommand("select * from tbl_user_details", connection);
           connection.Open();
           if (connection.State == ConnectionState.Open)
           {
                MySqlDataReader objSqlDataReader;
               objSqlDataReader = com.ExecuteReader();
                    while (objSqlDataReader.Read())
                     {
                     if (objSqlDataReader[2].ToString().Equals(txtUserName.Text) && objSqlDataReader[5].ToString().Equals(txtPassword.Text))
                     {
                          flag = 1;
                          Session["UserName"] = txtUserName.Text;
                          Session["UserType"] = objSqlDataReader[8].ToString();
                          Response.Redirect("ContactUs.aspx", false);
                     }
                     else
                     {
                          ClientScript.RegisterStartupScript(Page.GetType(), "validation", "<script language='javascript'>alert('Invalid Username and Password')</script>");
                    }
                }
           }
      }
      catch (Exception ex)
      {
           lblMsg.Text = ex.ToString();
      }
      finally
      {
           connection.Close();
      }

UK ASP.NET 4.5.2 Hosting - HostForLIFE.eu :: How to Use NServiceBus with ASP.NET SignalR ?

November 24, 2014 06:35 by author

Peter

In this tutorial, I will tell you how to use NServiceBus with ASP.NET SignalR. In detail right listed below what I'm planning to do is periodically publish an event utilizing NServiceBus. I will be able to use a ASP.NET MVC application as my front end and there I will be able to use a an additional NServiceBus client and that is liable for capturing event broadcasted from the NServiceBus publisher. Then working with ASP.NET SignalR, I will certainly be updating the UI with others captured events content.

First, Add a new ASP. NET MVC application to the solution.

Currently I'm running NServiceBus. Host and Microsoft ASP. NET SignalR nuget packages on ASP. NET MVC project using Package Manager Console. NServiceBus. Host can add the EndpointConfig. cs towards the project and I'm keeping as it's. Currently I'm making a folder named “SignalR” within my project and I'm heading to add a brand new category there named “EventMessageHandler”.
public class EventMessageHandler : IHandleMessages<MyMessage>
{
    public void Handle(MyMessage message)
    {
    }
}
When the NServiceBus has revealed an event of kind “MyMessage”, “Handle” method in “EventMessageHandler” class can tackle it. For the moment, lets maintain the “Handle” method empty and let’s add a OWIN Startup class towards the project by right clicking upon the App_Start folder and selecting a OWIN Startup class template.

Next step, I am modifying the created OWIN Startup class with these code:
using Owin;
using Microsoft.Owin;
using NServiceBus;
[assembly: OwinStartup(typeof(NServiceBusSignalRSample.Startup))]
namespace NServiceBusSignalRSample
{
    public class Startup
    {
        public static IBus Bus { get; private set; }
        public static void Configuration(IAppBuilder app)
        {
            Bus = Configure
                    .With()
                    .DefaultBuilder()
                    .DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("NServiceBusSignalRSample.Messages"))
                    .PurgeOnStartup(false)
                    .UnicastBus()
                    .LoadMessageHandlers()
                    .CreateBus()
                    .Start();
            app.MapSignalR();
        }
    }
}

Right listed below I've configured my NServiceBus host and I'm mapping SignalR hubs towards the app builder pipeline. Next action is to make a SignalR hub. For the I'm adding the listed class towards the previously produced “SignalR” folder.
public class MyHub : Hub{
    public void Send(string name, string message)
    {
        Clients.All.addNewMessageToPage(name, message);
    }
}
Currently right listed below I'm deriving “MyHub” class from “Hub” and I ve got a method there named “Send” that takes 2 parameters. Within the method, I'm calling the consumer aspect “addNewMessageToPage” that still I haven’t wrote.

Just before starting off using the client aspect code, let’s modify the “Handle” method in “EventMessageHandler” class now to call my hubs’ send method.
public class EventMessageHandler : IHandleMessages<MyMessage>
{
    public void Handle(MyMessage message)
    {
        IHubContext hubContext = GlobalHost.ConnectionManager.GetHubContext<MyHub>();
        hubContext.Clients.All.addNewMessageToPage(message.Message, "Peter");
    }
}

Next, I'm ready along with the back end code. Final thing to become done is to make a view in client side, initiate the hub connection and build a method named “addNewMessageToPage”. For the first I'm modifying the “HomeController” and adding a brand new Action there named “SignalR”.
public ActionResult SignalR()
{
    return View();
}

Then I'm correct clicking upon the Motion and making a new view along with a similar name “SignalR”. I'm modifying the “SignalR” view as follows.
@{
    ViewBag.Title = "SignalR";
}
<h2>SignalR</h2>
<div class="container">
    <ul id="output"></ul>
</div>
@section scripts {
    <script src="~/Scripts/jquery.signalR-2.1.1.min.js"></script>
    <script src="~/signalr/hubs"></script>
     <script>
       $(function () {
            $.connection.hub.logging = true;
            $.connection.hub.start();
            var chat = $.connection.myHub;
            chat.client.addNewMessageToPage = function (message, name) {
$('#output').append('<li>' + message + ' ' + name + '</li>');
};
        });
    </script>
}

Now I'm ready. One last factor to become done is to line multiple startup projects.

Finally, I'm running the Apps. Hope this post works for you!

ASP.NET 4.5.2 Hosting Germany - HostForLIFE.eu :: Learn How to Add or Update Record with GridView control in ASP.NET

November 21, 2014 05:08 by author

Peter

A Gridview is really a control for displaying and manipulating data from completely different data sources. It shows data from a sort of data sources inside a tabular format. Rather than boundfiled, I like to make use of TemplateField coz of the simplicity. In this article I am going to implement how to Add, Update, Delete selected record from GirdView control in ASP.NET 4.5.2

This the code for Add new record from footer and Update the selected row.

Default.aspx:
<asp:gridview allowpaging="True" autogeneratecolumns="False" cellpadding="4" forecolor="#333333" gridlines="None" id="gvstatus" onpageindexchanging="gvstatus_PageIndexChanging" onrowcancelingedit="gvstatus_RowCancelingEdit" onrowcommand="gvstatus_RowCommand" onrowediting="gvstatus_RowEditing" onrowupdating="gvstatus_RowUpdating" onselectedindexchanged="gvstatus_SelectedIndexChanged" runat="server" showfooter="True" width="600px">
<columns>
<asp:templatefield headerstyle-horizontalalign="Left" headertext="SrNo ">
<itemtemplate>
<%# Container.DataItemIndex + 1 %>
</itemtemplate>
</asp:templatefield>

<asp:templatefield headertext="ID" visible="false">
<itemtemplate>
<asp:label columnname_id="" id="lblid" runat="server" text="<%# Bind(">"> </asp:label>
</itemtemplate>
</asp:templatefield>
<asp:templatefield headertext="EmpName">
<itemtemplate>
<asp:label columnname_empname="" id="lblEmpName" runat="server" text="<%# Bind(">"></asp:label>
</itemtemplate>
<edititemtemplate>
<asp:textbox id="txtEmpName" runat="server" text="<%# Bind("columnname_EmpName") %>"></asp:textbox>
</edititemtemplate>
<footertemplate>
<asp:textbox id="txtfEmpName" runat="server"></asp:textbox>
</footertemplate>
</asp:templatefield>
<asp:templatefield headertext="empSalary">
<itemtemplate>
<asp:label id="lblempSalary" runat="server" text="<%# Bind("columnname_EmpSalary") %>"></asp:label>
</itemtemplate>
<edititemtemplate>
<asp:textbox id="txtempSalary" runat="server" text="<%# Bind("columnname_EmpSalary") %>"></asp:textbox>
</edititemtemplate>
<footertemplate>
<asp:textbox id="txtfempSalary" runat="server"></asp:textbox>
</footertemplate>
</asp:templatefield>
<asp:templatefield itemstyle-width="190px" showheader="False">
<itemtemplate>
<asp:button causesvalidation="False" commandname="Edit" id="btnedit" runat="server" text="Edit"></asp:button>
</itemtemplate>
<edititemtemplate>
<asp:button causesvalidation="True" commandname="Update" id="btnupdate" runat="server" text="Update"></asp:button>
 <asp:button causesvalidation="False" commandname="Cancel" id="btncancel" runat="server" text="Cancel"></asp:button>
</edititemtemplate>
<footertemplate>
<asp:button commandname="Add" id="btnadd" runat="server" text="Add">
</asp:button></footertemplate>
</asp:templatefield>
</columns>
<pagerstyle backcolor="#A86E07" forecolor="White" horizontalalign="Center">
<selectedrowstyle backcolor="#E2DED6" font-bold="True" forecolor="#333333">
<headerstyle backcolor="#A86E07" font-bold="True" forecolor="White">
<editrowstyle backcolor="#d9d9d9">
<alternatingrowstyle backcolor="White" forecolor="#A86E07">
</alternatingrowstyle></editrowstyle></headerstyle></selectedrowstyle>
</pagerstyle>
</asp:gridview>

CodeBehind:
protected void Page_Load(object sender, EventArgs e)
    {
       if (!Page.IsPostBack)
       {
         gvBind(); //Bind gridview
       }
     }
public void gvBind()
{
SqlDataAdapter dap = new SqlDataAdapter("select id, empName,empSalary from myTable", conn);    DataSet ds = new DataSet();
     dap.Fill(ds);
     gvstatus.DataSource = ds.Tables[0];
     gvstatus.DataBind();
}
Update the select row from girdview
protected void gvstatus_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        lblmsg.Text = "";
        try
        {
            GridViewRow row = (GridViewRow)gvstatus.Rows[e.RowIndex];
            Label lblid = (Label)gvstatus.Rows[e.RowIndex].FindControl("lblid");
            TextBox txtname = (TextBox)gvstatus.Rows[e.RowIndex].FindControl("txtEmpName");
            TextBox txtSalary = (TextBox)gvstatus.Rows[e.RowIndex].FindControl("txtempSalary");
            string empName = txtname.Text;
            string empSalary = txtSalary.Text;
            string lblID=lblid.Text;
            int result = UpdateQuery(empName, empSalary,lblID);
            if (result > 0)
            {
                lblmsg.Text = "Record is updated successfully.";
            }
            gvstatus.EditIndex = -1;
            gvBind();
        }
        catch (Exception ae)
        {
            Response.Write(ae.Message);
        }
    }

And this is the Code that I used to add new record into database form GirdView footer
protected void gvstatus_RowCommand(object sender, GridViewCommandEventArgs e)
{
        if (e.CommandName == "Add")
        {
            string empName = ((TextBox)gvstatus.FooterRow.FindControl("txtfempName")).Text;
            string empSalry = ((TextBox)gvstatus.FooterRow.FindControl("txtfempSalary")).Text;
            int result = InsertNewRecord(empName, empSalry);
            if (result > 0)
            {
                lblmsg.Text = "Record is added successfully.";
            }
            gvstatus.EditIndex = -1;
            gvBind();
        }
    }
protected void gvstatus_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gvstatus.EditIndex = -1;
gvBind();
}
protected void gvstatus_RowEditing(object sender, GridViewEditEventArgs e)
{
lblmsg.Text = "";
gvstatus.EditIndex = e.NewEditIndex;
gvBind();
}
public void UpdateQuery(string empName, string empSalary, string lblID)
{
SqlCommand cmd = new SqlCommand("update myTable set empName='" + empName + "',empSalary='" + empSalary + "' where id='" + lblID + "'", conn);
conn.Open();
int temp = cmd.ExecuteNonQuery();
conn.Close();
return temp;
}
public void InsertNewRecord(string empName, string empSalary)
{
SqlCommand cmd = new SqlCommand("your insert query ", conn);
conn.Open();
int temp = cmd.ExecuteNonQuery();
conn.Close();
return temp;
}

ASP.NET 4.5.2 Hosting UK - HostForLIFE.eu :: How to Create PDF from DataTable in ASP.NET 4.5.2 ?

November 17, 2014 05:58 by author

Peter

With this article, i'm explaining you learn how to create PDF File from datatable with ASP.NET 4.5.2. I'm passing a DataTable during this function and code to convert this in pdf file. I'm working with iTextSharp you'll be able to download it from internet. It totally free. you will need to make an easy ASP.NET page and have data from database. Then pass it to ExportToPDF method. We are able to established PDF page margins, alter page orientation (portrait, landscape), custaomize headers and footers add page numbers and a lot of. Carry out a few R & D along with iTextSharp.

And here is the code that I use to create PDF file from DataTable:
public void ExportToPdf(DataTable myDataTable)
   {
     Document pdfDoc = new Document(PageSize.A4, 10, 10, 10, 10);
    try
     {
       PdfWriter.GetInstance(pdfDoc, System.Web.HttpContext.Current.Response.OutputStream);
       pdfDoc.Open();
       Chunk c = new Chunk("" + System.Web.HttpContext.Current.Session["CompanyName"] + "", FontFactory.GetFont("Verdana", 11));
       Paragraph p = new Paragraph();
       p.Alignment = Element.ALIGN_CENTER;
       p.Add(c);
       pdfDoc.Add(p);
       string clientLogo = System.Web.HttpContext.Current.Session["CompanyName"].ToString();
       clientLogo = clientLogo.Replace(" ", "");
       string clogo = clientLogo + ".jpg";
       string imageFilePath = System.Web.HttpContext.Current.Server.MapPath("../ClientLogo/" + clogo + "");
       iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);
       //Resize image depend upon your need
       jpg.ScaleToFit(80f, 60f);
       //Give space before image
       jpg.SpacingBefore = 0f;
       //Give some space after the image
       jpg.SpacingAfter = 1f;
       jpg.Alignment = Element.HEADER;
       pdfDoc.Add(jpg);
       Font font8 = FontFactory.GetFont("ARIAL", 7);
       DataTable dt = myDataTable;
       if (dt != null)
       {
         //Craete instance of the pdf table and set the number of column in that table
         PdfPTable PdfTable = new PdfPTable(dt.Columns.Count);
         PdfPCell PdfPCell = null;
         for (int rows = 0; rows < dt.Rows.Count; rows++)
         {
           for (int column = 0; column < dt.Columns.Count; column++)
           {
             PdfPCell = new PdfPCell(new Phrase(new Chunk(dt.Rows[rows][column].ToString(), font8)));
             PdfTable.AddCell(PdfPCell);
           }
         }
         //PdfTable.SpacingBefore = 15f; // Give some space after the text or it may overlap the table
         pdfDoc.Add(PdfTable); // add pdf table to the document
       }
       pdfDoc.Close();
       Response.ContentType = "application/pdf";
       Response.AddHeader("content-disposition", "attachment; filename= SampleExport.pdf");
       System.Web.HttpContext.Current.Response.Write(pdfDoc);
       Response.Flush();
       Response.End();
       //HttpContext.Current.ApplicationInstance.CompleteRequest();
     }
     catch (DocumentException de)
     {
       System.Web.HttpContext.Current.Response.Write(de.Message);
     }
     catch (IOException ioEx)
     {
       System.Web.HttpContext.Current.Response.Write(ioEx.Message);
     }
     catch (Exception ex)
     {
       System.Web.HttpContext.Current.Response.Write(ex.Message);
     }
   }
