I am new to C# , i've build a simple web form which shows a result based on 4 pulldown menus. I wish to save this result during the session the user spends on the website, untill the user resubmits the form. So when coming back to the result page, the search results are still shown.http://www.estatewise.nl to see the form in action.
View 3 RepliesI have a E-Shop Site and I need some customization for my users like following :
Store favorite products in their own basket.Customize products list in order to what are their favorite. It must remember their basket next time they want to visit our site.
my question is how I can store information for my customers who are new to my web site also most of customers don't like to have username and password then login first they like to buy during a week and at the end of week pay for them then we can send some products to their locations.

i'm using this to save a cookie when users marks the remember me box but its not working.
I'm currently developing a website using .net MVC 3 and I'm on the authentication layer...Here is the scenario: user is logged with the "remember me" option checked : a user Session is created on the server as well as the authentication cookie on the client side.The Session timeout is set to 20 minutes.After 25 minutes of inactivity the user goes back onto the website and Session, now expired, does not exist anymore but the authentication cookie still exists
View 1 RepliesIs there room for issue in the following code in terms of multiple users of the same web application? I mean, I know that a purely static string will be shared across all sessions for a single ASP.NET application, but since this explicitly refers to the Current.Session, even though it is static it seems like it would always refer to the session instance of the "current user." But an error is happening that could be explained by everyone sharing the current value of Mode and thus the most recent change overwriting everyone else's mode value. (As a background: This string is in a Helpers class that is used throughout the application. I do not want to make references to Session["Mode"] throughout the application and do not want to have to pass Session["Mode"] in every method call from an aspx.cs page.)
public static string Mode
{
get
{
var value = HttpContext.Current.Session["Mode"];
return (value ?? string.Empty).ToString();
}
set
{
HttpContext.Current.Session["Mode"] = value;
}
}
In login control of asp.net there is a remember me checkbox. What is the functionality of this checkbox? What it does basically? Is there any way to put space between checkbox and its associated label?
I saw Windows Live login control has an extra checkbox Remember my password? How can we achieve this feature in our custom login control? I have read many tutorials but I can not able to solve my queries.
I am always thinking about validation in any kind on the webpage (PHP or ASP, it doesn't matter), but never find a good and accurate answer. For example, a I have some GET-Parameter, which defines a SQL query like DESC oder ASC. (SQL-Injection?) Or I have a comment-function for user, where the data is also saved in a database.
Is it enought to check for HTML-tags inside the data? Should the validation done before adding it to the database or showing it on the page? I am searching for the ToDo's which should be always performed with any data given from "outside".
I have the following question on how to do the following:I have developed a website and I want certain users to give to possibility to add a text article to specific pages or maybe into a Forum. These articles are more or less having the same structure like:Big Header, manchet (intro), text with in between small headers. I would like to have this all in the same font-family and depending on the sort of text in a certain font-size.I was thinking of using TinyMCE as a base, because all typographical aspects are in there and it is also possible to add graphics and other video stuff to itt.Is this possible to use this, since I recently found TinyMCE and do not have the knowledge yet about this?And how should the structure be set up?I do hope someone could give some clues or sites where this is discussed.
View 4 RepliesI've written a small class .That has a method for adding and subtracting.
My class file is fine and everything works well when I hard code the integer values. But the moment I try to use textboxes in my methods signature to accept values it complains that this is an inavlid argument. I assume that this is because I used int as my signatures but then how can i use my class to textboxes as input.

My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted).
I am able to replicate this with the following ASPX code (with no code behind):
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="fuTest" runat="server" />
<asp:Button ID="btnSubmit" runat="server" Text="Submit" />
</div>
</form>
</body>
</html>
(Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box)
Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields.
I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers.
i have a login, and wanted to know how i could use the remember me function, (so each time the user visits the site, even though they are not logged in, it would auto log them in) but without using the actual remember me checkbox. Is there any extra code i need to write, and if so, what?
View 11 RepliesHOW TO Force C#/ASP.NET to not rename input elements to work consistantly with Form.GetValues.
ASP.NET changes the "name" property of input elements set with "runat=server" to match their ID property at run time. This causes server-side calls to HttpRequest_Page.Form.GetValues to now be able to get the expected Form element.
Example:
.aspx page...
<input type=text id=txtMY_NAME name="MY-NAME" runat=server>
<input type=hidden id=hidMY_SECRET name="MY-SECRET" runat=server>
.aspx.cs file:
string csNAME = HttpRequest_Page.Form.GetValues("MY-NAME"); // Fails...
string csSECRET = HttpRequest_Page.Form.GetValues("MY-SECRET"); // Fails...
The reason why this fails is because ASP.NET changes the "name" properties of these controls to match their "ID". Thus at run time they become as such:
.aspx at run-time
<input type=text id=txtMY_NAME name="txtMY_NAME" runat=server>
<input type=hidden id=hidMY_SECRET name="hidMY_SECRET" runat=server>
I do not want ASP.NET doing this. I do not want to change the naming convention of my id properties either. In fact, I need the ID to be different than the name, as I use client side script to change/create/delete controls on the fly.
What can one do?
is there any reason for me to place the session ID within a form, as a hidden form field?

View 2 RepliesI have an asp.net website in which users can submit reports. Another tester and I tested this page at the same time and when I went to review the information I submitted, it displayed information that I didn't submit. It displayed the info submitted from the other user.
I use session variables for these values. I don't understand how this happened? What can I do so each user can individually submit their information without overlapping some one else's information? The plan is for multiple users to be able to use this page to submit their weekly layer reports.
The first example of code is how I add the session variables from the textboxes.

The second one is how I display them in labels on a confirmation page.

I'm wondering if it's possible to perhaps set something up in the global.asx file or something that will build a list of all currently active user sessions that I can then use to display to a logged in user, who else is currently logged in.
Currently I store my userId's in a session variable Session["IsLoggedIn"], so basically i want to build an global array of some sort that will store all these active userId's.
Let me know if this is possible, or who i would go about accomplishing this sort of thing. BTW, I'm not using asp.net's built in membership thing for login accounts.
I have a background set of images that is called randomly.It changes each time a user opens a new page and refreshes the same page.Not 100% of what I want.
Ideally I would like a random image to be shown each time a user comes to the site but not on every page.
Is there a way to set the image per the session a users visits the site instead of each page?
