I want my code to refresh the page once its shown the success label for 3 seconds.
How can i do this in c# code?
i have this following:
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
using System.IO;
public partial class CAPTCHA_Contact : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//ImageVerification
if (!IsPostBack)
{
SetVerificationText();
}
imCaptcha.ImageUrl = "captcha.ashx?d=" + DateTime.Now.Ticks;
}
public void SetVerificationText()
{
Random ran = new Random();
int no = ran.Next();
Session["Captcha"] = no.ToString();
}
protected void CAPTCHAValidate(object source, ServerValidateEventArgs args)
{
if (Session["Captcha"] != null)
{
if (txtVerify.Text != Session["Captcha"].ToString())
{
SetVerificationText();
args.IsValid = false;
return;
}
}
else
{
SetVerificationText();
args.IsValid = false;
return;
}
}
protected void btnSave_Click(object sender, EventArgs e)
{
if (!Page.IsValid)
{
return;
}
SetVerificationText();
//Save the content
MailMessage mail = new MailMessage();
mail.From = new MailAddress(EmailTB.Text);
mail.To.Add("name#company.co.uk");
mail.Bcc.Add("test#test.co.uk");
mail.Subject = "Web Quote";
mail.IsBodyHtml = true;
mail.Body = "First Name: " + FNameTB.Text + "<br />";
mail.Body += "Email: " + EmailTB.Text + "<br />";
mail.Body += "Telephone: " + TelephoneTB.Text + "<br />";
mail.Body += "Query: " + QueryDD.Text + "<br />";
mail.Body += "Comments: " + CommentsTB.Text + "<br />";
SmtpClient smtp = new SmtpClient();
smtp.Host = "localhost";
smtp.Send(mail);
sucessPH.Visible = true;
}
protected void Reset(object s, EventArgs e)
{
FNameTB.Text = "";
QueryDD.Text = "";
EmailTB.Text = "";
TelephoneTB.Text = "";
CommentsTB.Text = "";
txtVerify.Text = "";
}
}
So after sucessPH.Visible = true; i need to count 3 seconds and then refresh the page. This will then clear the form data and the user will also get 3 seconds to see the message to say the message was successfull.
Any ideas?
Since this is a client-side concern and not a server-side concern, you'll want to do this with JavaScript. Keep in mind that by the time the page is sent to the client all of the server-side code has completed and disposed. Trying to do this with server-side code will result in a lot of unnecessary complexity in this case.
In JavaScript you can reload the page with a delay with something like this:
setTimeout("window.location.reload()", 3000);
Well, if you're using webforms, you could use an update panel, and then use the timer component, just like this guy've done
Tutorial: How to refresh an UpdatePanel control at a timed interval
Right after sucessPH.Visible = true; add following line: ClientScript.RegisterClientScriptBlock(this.GetType(), "refresh", "setTimeout('window.location.href=window.location.href', 3000);", true);
Well.. you are in a web..
So your server can count 3, but you need the client to count 3 and then postback it to the server...
If your server only counts, then the user will not view anything..
Just make your application ajax enable, and use a timer ;)
This is the code for the page
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="3000" ontick="Timer1_Tick">
</asp:Timer>
</div>
</form>
</body>
</html>
and in the code behind you have this:
protected void Timer1_Tick(object sender, EventArgs e)
{
//do your thing when reach this tick
}
This page will refresh exactly every 3 seconds.
This is .net 4.

I need to convert a pdf file into jpeg using c#.
The solution (dll library) have to be free.
I have searched a lot of information on the web but seems that the library pdfiumviewer might be helpful here. It is also available as nuget.
I have tried this code without success, because the new file in jpg format is not saved.
How to do resolve this?
using PdfiumViewer;
using System;
using System.Drawing.Imaging;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
try
{
using (var document = PdfDocument.Load(#"sample.pdf"))
{
var image = document.Render(0, 300, 300, true);
image.Save(#"output.png", ImageFormat.Png);
}
}
catch (Exception ex)
{
// handle exception here;
}
}
}
}
Edit #01
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
try
{
using (var document = PdfDocument.Load(#"C:\\Users\\aaa\\Documents\\Visual Studio 2013\\WebSites\\GroupDocsConversion\\sample.pdf"))
{
var image = document.Render(0, 300, 300, true);
image.Save(#"C:\\Users\\aaa\\Documents\\Visual Studio 2013\\WebSites\\GroupDocsConversion\\output.png", ImageFormat.Png);
}
}
catch (Exception ex)
{
Response.Write("Error: " + ex.Message);
}
}
}
Try this combined solution with iTextSharp and Ghostscript.NET ( available on Nuget ).
If necessary install Ghostscript 9.52 for Windows (32 bit)
I hope I was helpful.

I`m trying to make an ASP.NET basic site that connects to a database. It's supposed to allow a user to register and log in.
I check the input with javascript and in the code behind in case it's disabled.
The problem is that whenever i click the register, login, or logout buttons for the first time they won't work; The page remains the same.
The second time, however, they work perfectly.
Debugger says it's called both times.
any ideas?

EDIT: A friend of mine adviced me to take a look in the ASP.NET page lifecycle, and it might have something to do with the database interactions being done after the page is presented, if it helps anyone.
Your friend is correct, you need to understand the page the Page Life cycle better. Basically in this instance you need to understand that the OnLoad event happens before any click events. You can see this for yourself by adding a break point to the OnLoad event and the click handler. You will see that the order of events as they happen.
In this instance I would writ a method to set up the page, and then call this in each of the on click events
private void setUpPage()
{
if (Session["User"] != null)
{
RegisterRelated.Visible = false;
LoginRelated.Visible = false;
InPage.Visible = true;
WelcomeTag.Text = "Welcome, " + ((User)Session["User"]).Username + ".";
}
else
{
RegisterRelated.Visible = true;
LoginRelated.Visible = true;
WelcomeTag.Text = String.Empty;
InPage.Visible = false;
}
}
protected void Page_Load(object sender, EventArgs e)
{
//Call if not in response to button click
if(!IsPostBack)
{
setUpPage();
}
}
protected void Register_Click(object sender, EventArgs e)
{
Label Reply = new Label();
if (Session["User"] == null)
{
Result myRegResult = Result.IN_PROG;
User myAddedUser = new User(UserTB.Text, PasswordTB.Text, EmailTB.Text);
DbManager.OpenDbConnection();
myRegResult = DbManager.Register(myAddedUser); //Connection with the database.
Reply.Text = resultToString(myRegResult);
Reply.ForeColor = resultColor(myRegResult);
}
else
{
Reply.Text = "You must log out before you register.";
Reply.ForeColor = resultColor(Result.EXEC_ERROR);
}
Answer.Controls.Add((Control)Reply);
//Reset_Fields();
//Reset the fields as required AFTER you have done what you need with the database
setUpPage();
}
protected void Login_Click(object sender, EventArgs e)
{
Label Reply = new Label();
LoginProc Status = LoginProc.IN_PROG;
DbManager.OpenDbConnection();
Status = DbManager.Login(LoginUserTB.Text, LoginPassTB.Text); //Connection with the database
Reply.Text = ProcToString(Status);
Reply.ForeColor = ProcToColor(Status);
LogAnswer.Controls.Add(Reply);
if (Status == LoginProc.FINE)
Session["User"] = new User(LoginUserTB.Text, LoginPassTB.Text, null);
//Reset_Fields();
//Reset the fields as required AFTER you have done what you need with the database
setUpPage();
}
protected void logout_Click(object sender, EventArgs e)
{
Session["User"] = null;
//Reset the fields as required AFTER you have done what you need with the database
setUpPage();
}
When you click the login or register button, page load event works firstly, and after button click event works.
I can see that, you set to page display in page load event and set to Session value in button click event. So at first click, page load event triggered first, but there is no Session value yet. Page load event finishes and resume with button click event, so Session value is not null now (if entered user info is valid).
It is the reason why page work at second click.
Solution:
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack) //just write this
return;
if (Session["User"] != null)
{
RegisterRelated.Visible = false;
LoginRelated.Visible = false;
InPage.Visible = true;
WelcomeTag.Text = "Welcome, " + ((User)Session["User"]).Username + ".";
}
else
{
RegisterRelated.Visible = true;
LoginRelated.Visible = true;
WelcomeTag.Text = String.Empty;
InPage.Visible = false;
}
}
Note: I got your code and tried.

I think there is issue with validators. Please set causes validation property of buttons according to your requirements.
Try Page_BlockSubmit = false; before every return false;
My registration used to be working completely fine, but I have since done multiple modifications to it, so I can't find out what has caused this problem...
When I enter details and click Register, the page takes a long time to process, using the asp.net local server. It then finally says I've registered, but has entered 10-30 entries into the database (some aren't even identical, with different fields missing etc)
I can clear all the created entries in the database, then re-open it, and it has added 10-30 more... it will keep doing this until I kill the asp.net development server it creates when I "start without debugging".
Here is the c# file for the page:

Appreciate any help as to why this may be happening, as the assignment is due later today.
Instead of passing these methods in Page Load, write them into the button click event as.
protected void btnRegister_Click(object sender, EventArgs e)
{
//Save the registration data into database, 17/8/2014
SaveRegistration();
sendEmail();
}
Change the html markup of Register button as,
<asp:Button type="button" CssClass="caption" Text="Register" ID="btnRegister" onclick="btnRegister_Click" onClientClick="javascript:btnRegister_OnClick();"/>
i have an aspx, aspx.cs file, in the aspx file i m using javascript functions,
in the javascript code i use the getter (<%=getSize%>) method defined in the aspx.cs file,
but the page returns: "The Controls collection cannot be modified because the control contains code blocks" why?

You haven't posted the full HTML but try to move your script out of the <head> tag.
Is getSize a property or a function? If its a property size will take the value that it is at page load, if the its a function then you need to look at page methods as you cannot call it in this way, heres an example
We use email address instead of user id. But when the user enters his email address into the password recovery form and submits it, the site returns "We were unable to access your information. Please try again." and replaces the email value in the text box with a long string of characters and numbers (e.g. e61686cb-93a5-4737-8c40-52g8eb01bb67).
Here's the relevant aspx page code...
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1"
runat="server">
<div class="login_page">
<div class="login_header">Password Reset</div>
<div class="login_body">
<asp:PasswordRecovery ID="PasswordRecovery1" runat="server"
onverifyinguser="PasswordRecovery1_VerifyingUser"
onsendingmail="PasswordRecovery1_SendingMail">
</asp:PasswordRecovery>
</div>
</div>
</asp:Content>

Without knowing a lot about ASP.NET membership, my guess would be that the line:
PasswordRecovery1.UserName = username;
// where username = Membership.GetUserNameByEmail(PasswordRecovery1.UserName);
is causing your problem. Even though you say you're not using username in your model, I'd bet that ASP.NET populates the username column in your database with a GUID. Take a look at your database, and see if that GUID matches up with the username column in your table for this user.
