I'm creating image (jpg) at run time in my application (ASP.NET/C# 3.0). I need to delete the created image after 30 mins. So is it possible to set expiration to the image after 30 mins when creating the image like setting expiration to cookies.
I'm programatically sending an email and I want to set it to expire after a certain amount of time. I tried using the following but it doesn't seem to work:
message.Headers.Add("Expires", Now.AddMinutes(2))
I can see the value in the header but the email doesn't actually expire.

I am not sure if I am asking this question correctly. Sometimes when you don't know enough, you may not know what to ask. I want to set up memberships with an ASP.NET website. The memberships will have a 14 day free trial period. After that, the user will need to pay a fee if they wish to continue to access the website. I am not sure how to accomplish this. After adding a membership database to the website, setting up roles ect., what do I do next? Do I need to make adjustments to the tables of the database, or write some code somewhere in the application? I have never done this exercise before, Logically, I know that I need to implement something that keeps track of expiration date. Also, how do I prevent a user from just making up new user names and credentialing?
I am creating some cookies in my ASP.NET application. These cookies expire 10 minutes after they have been created. I follow the approach described on MSDN as shown here:[URL]
My question is, when a cookie "expires", what happens? Does the browser automatically delete the cookie? Is it our responsibility as developers to remove the cookies if they exist and have expired?
1) How/where do I set the lifetime of the session cookie in my web application when using an STS to get claims? From what I can tell, it seems I can only do this programmatically in the erviceConfigurationCreated event.
2) How/where can I make sure that the expiration is sliding?

I've been doing web development for a while and have yet to read a good answer to this question: iven a page that executes transactions through a postback, how do you prevent the user from duplicating the transaction when they do something as simple as hit the back button? I've explored trying expire the cache but I must admit I'm lacking in my understanding of ASP.NET caching. What is the approach I should use to make the old request stale and invalid?
I have asp.net application. I'm using external javascript files in my application. When I test my site with page speed tool from google it says that following resources are missing a cache expiration. also some of the images and css files.
I am in need for setting content expiration to immediate for certain parts of my website. Basically we want to expire the "shopping" pages but the browsing pages shouldn't expire allowing users the ease of using the back button to browse around. Is there a way to enable it per page, master page, folder, or something?
am a ASP.NET developer using Facebook Developer Toolkit to develop a facebook flash application with flash developer.When the user plays the game for a certain period of time, there are chances that the facebook session expires and I can't call any Facebook API for processing as a result.
I have a web app that contains 1 master page and a bunch of content pages. One of the content pages is "SysLogin.aspx", which is called from a menu option from the Master Page. When the page is called, the user logs in. However, there is a "Login" button. In the code behind of the Login_Click() event, the the user successfully logs in, they are supposed to be redirected to a "Default.aspx" page and the Main Menu is enabled. Problem is, the app hangs on the redirect statement and it goes to the Catch portion of the Try Catch construct. For some reason, when I examine the exception, it only says "Unable to evaluate expression". Below is my code. My question, other than what I've stated is...should your application be controlled using code in the Master Page or in child pages. My code from the "SysLogin.aspx" is below. It hangs on the highlighted line of code.
Private Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogin.Click Try If txtLoginID.Text.Length > 0 Then If txtPassword.Text.Length > 0 Then If dbIO.ValidateUser(txtLoginID.Text, txtPassword.Text) Then Session("LoggedIn") = txtLoginID.Text Session("loggedInOk") = "Y" Response.Redirect("~/Admin/Default.aspx") End If End If End If Catch ex As Exception Master.errMsg = dbIO.DisplayError("btnLogin_Click()", "SysLogin", ex.Message) End Try End Sub
I was wondering if anyone knew if it was possible to control a collapsible panel with a drop down list?
For example. Say the drop down list has options, 1, 2, 3, 4. I want to hook up panels that go to each option. So when the user selects 1, panel one is shown, when user selects 4 panel 4 is shown.
i want to make a web site which is able to control a hardware on a clients computer.
the the hardware for example be a simple gsm modem
this is a general question, for asking of methods and opinions as for the following
control this hardware using the computer the hardware is connected to. control this hardware using another computer over a network control this hardware using a web site application or a simple web site
the thing to consider --> this is a class group project which we implement in c# asp.net.
edit
hope the broadness is narrowed down.
assume there is a remote control attached to the comm port of my computer, which controls a small car.
i want user around the world to be able to move the car using there keyboard.
i can write a desktop app to control the remote using the printer port but thats on my local host only.
With my model, I have one view model using another as its base. In my case, BaseUserModel is inherited by CreateUserModel, in order to share common properties such as Username and Password. My CreateUserModel adds to that by having ConfirmPassword, Email, SecurityQuestion, etc.
My problem is, when using the ValidationSummary() Html helper, the validation is obviously in order of the properties in my model. Basically, because of the inheritance I have going on here, the errors are not in the correct order.
Is it possible to control when or how these validation rules are added to the list? The only attribute I'm using is Required.
I'm writing a web application for display on smartphones and multimedia phones. If I go with the default web page size then the phone resizes the page so small that it is impossible to read the text. Fixing the width of the objects on the page to 200 px wide has no effect. The device still tries to display the entire page.
So I'd like to find a way to force all the pages to be no more than 200 px wide.
I don't know if the following is possible or not but in brief, here is what I'm trying to achieve:
1. When a user requests to view a document, they click on a link (could be other) which contains an encrypted query string containing data required to retrieve the relevant document. i.e.[URL]
2. I want to ensure that if after x minutes the user goes back to their history and select the link again or re-type the same url as above that it will not request the document and redirect them to a page letting them know that the requested document "link" is no longer valid.
I don't want to rely on cookies or sessions, so thought that maybe there would be a way to add a datetime token at the end of the existing url but this needs to be done at run-time as the url is already predefined when the link is created, so I'm not sure how can I do this?
ideally, I'd like something like this [URL] where the token would contain the date & time when the link was clicked.
Once re-requested, I would decrypt the token and validate it again the server time and if it was over the x minutes defined, it would redirect me to the "link is no longer valid" page.
