I've got this method here, I wanted to go e.Mail.To = MAC, but apparently it's a read only property, which leaves me completely stumped on how I can programmatically set the recipients. Basically I want to change the to address based on my deployment level (live/test/dev) I also want to dispose() (not send) the email for dev/test modes.
Is there another way round this?
public static void ErrorMail_Mailing(object sender, ErrorMailEventArgs e)
{
if (!GlobalHelper.IsLiveMode)
{
e.Mail.Dispose();
}
else
{
MailAddressCollection MAC = new MailAddressCollection();
MAC.Add("A");
}
Following snippet will solve your problem -
public static void ErrorMail_Mailing(object sender, ErrorMailEventArgs e)
{
if (!GlobalHelper.IsLiveMode)
{
e.Mail.Dispose();
}
else
{
MailAddressCollection MAC = new MailAddressCollection();
MAC.Add("A#XYZ.COM");
MAC.Add("B#XYZ.COM");
e.Mail.To.Clear(); // Clears any existing mail addresses if you want to
e.Mail.To.Add(MAC.ToString()); // To contains A#XYZ.COM & B#XYZ.COM
}
}

How can I programmatically stop or start a website in IIS (6.0 and 7.0) using MsBuild?
(3 answers)
Closed 7 years ago.
I am using the MVC5 for an web application. The web app runs in IIS7 or greater.
In the Global.asax on application_start, the number of licenses will be set:
protected void Application_Start()
{
try
{
MyApp.cNumberOfLicenses = COM.GetNumberOfLicenses();
}
catch(Exception e)
{
// log exception
// stop web site.
}
}
If any expection will be thrown in this context, the web site should shut down as you can do that in the IIS-Manager:
How can I stop the current web site in my Application_Start ?
You can do it with the help of "Microsoft.Web.Administration.dll"
using Microsoft.Web.Administration;
After adding the reference of "Microsoft.Web.Administration.dll" write below code in Global.asax
protected void Application_Start(object sender, EventArgs e)
{
try
{
MyApp.cNumberOfLicenses = COM.GetNumberOfLicenses();
}
catch (Exception e)
{
// get the web site name
var lWebSiteName = System.Web.Hosting.HostingEnvironment.ApplicationHost.GetSiteName();
// log exception
// stop web site.
using (ServerManager smg = new ServerManager())
{
var site = smg.Sites.FirstOrDefault(s => s.Name == lWebSiteName);
if (site != null)
{
//stop the site...
site.Stop();
}
}
}
}
I will go not with stop it, but to show some message if you do not have license.
This is an example, and an idea.
You can use this code on global.asax where if you do not have licenses the moment you start, you open a flag, and after that you do not allow any page to show, and you send a page that you can keep on an html file.
private static bool fGotLicense = true;
protected void Application_Start()
{
try
{
MyApp.cNumberOfLicenses = COM.GetNumberOfLicenses();
}
catch(Exception e)
{
// log exception
// stop web site.
fGotLicense = false;
}
}
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
// if not have license - let show some infos
if (!fGotLicens)
{
// the file we look now is the app_offline_alt.htm
string cOffLineFile = HttpRuntime.AppDomainAppPath + "app_offline_alt.htm";
// if exist on root
if (System.IO.File.Exists(cOffLineFile))
{
using (var fp = System.IO.File.OpenText(cOffLineFile))
{
// read it and send it to the browser
app.Response.Write(fp.ReadToEnd());
fp.Close();
}
}
// and stop the rest of processing
app.Response.End();
return;
}
}
You can have a file named app_offline.htm with content say This website is offline now in web server and copy that to root directoy of website you want for any event.
It will directly show that message, but yes, App pool will be still ON, when you need to start , you just need to rename that to something else.
we are using HttpModule for switching aspx pages..
But if large number of client try to hit same time then people get wrong page on screen... I am not sure if something wrong in my code due to Server.TransferRequest.
Can any one give any suggestion?
public class SwitchMasterModule : IHttpModule, IRequiresSessionState
{
public void Init(HttpApplication context)
{
context.BeginRequest += Context_BeginRequest;
}
void Context_BeginRequest(object sender, EventArgs e)
{
var AppId = SiteSettings.ApplicationId().ToString();
if (HttpContext.Current.Request.CurrentExecutionFilePath.Equals("/default.aspx", StringComparison.InvariantCultureIgnoreCase))
{
HttpContext.Current.Server.TransferRequest(string.Format("~/Templates/{0}/default.aspx", AppId), true);
}
}
}
Moved from comment to answer.
It might be that SiteSettings.ApplicationId() returns incorrect value.
I don't know what the origin of the SiteSettings class is, but if it's not absolutely thread-safe, you could easily wind up with one user accessing the ApplicationId value appropriate for another user.
I'm creating a C# application with a ASP.net frontend, however I'm having a problem at the moment. I want to the user to enter some information, which once submitted, will be displayed within a listbox on the page which works fine. However, once I close the page, stop debugging the program and run it again - the information is still displayed but I want it to start off blank. Here if the ASPX page that I think if causing the issue, it's driving me mad.
public partial class CarBootSaleForm : System.Web.UI.Page, ISaleManagerUI
{
private SaleList saleList;
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack && Application["SaleList"] != null)
{
LoadData();
}
else
{
saleList = (SaleList)Application["SaleList"];
}
if (saleList != null)
{
UpdateListbox();
}
}
private void UpdateListbox()
{
lstSales.Items.Clear();
if (saleList != null)
{
for (int i = 0; i < saleList.Count(); i++)
{
lstSales.Items.Add(new ListItem(saleList.getSale(i).ToString()));
}
}
}
protected void btnAdd_Click(object sender, EventArgs e)
{
Application.Lock();
Application["SaleList"] = saleList;
Application.UnLock();
Response.Redirect("AddSaleForm.aspx");
}
}
Forget the LoadData() within the page load as it's not actually loading anything at the moment :)
Any help is really appreciated!
The variables stored in Application state are not flushed unless you restart the web server, so you will need to use the iisreset commmand (on command-line) if you are using IIS, or you will need to stop the ASP.NET web server (use the tray icons) after each debugging session.
if it is not postback you can add
Session.Abandon(); in the else block in Page_load.
Kill Session:
How to Kill A Session or Session ID (ASP.NET/C#)
In my ASP.NET MVC3 web application I'd like to add a small message displaying the number of users currently browsing the site.
I'm currently using Session_Start and Session_End application events to increment or decrement a static property inside Global.asax.
This works, but it isn't precise at all. Since my session timeout is configured to 20mn there's a huge delay between updates.
Is there a more elegant, precise way of doing this?
I've thought of calling an action via AJAX which simply does Session.Abandon() on the window.onbeforeunload javascript event, but this would be called each time the user changed pages. Is there a way to determine when the user closes his browser or leaves the domain?
Any hints, comments or code examples would be welcome!
Here is the relevant part of current code:
public class MvcApplication : System.Web.HttpApplication
{
public static int UsersConnected { get; set; }
protected void Session_Start(object sender, EventArgs e)
{
Application.Lock();
UsersConnected++;
Application.UnLock();
}
protected void Session_End(object sender, EventArgs e)
{
Application.Lock();
UsersConnected--;
Application.UnLock();
}
...
}
Okay this was a bit tricky but I've come with an 'okay' solution.
First, Ive created a static dictionary in Global.asax which will store the IP address of the clients and their last poll date.
public class MvcApplication : System.Web.HttpApplication
{
public static Dictionary<string, DateTime> ConnectedtUsers { get; set; }
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
ConnectedtUsers = new Dictionary<string, DateTime>();
}
...
}
Then, in my CommonsController, I've created this action which will add new clients, remove clients which haven't been polled in the last 30 seconds and update the poll date of already registered clients :
public class CommonsController : Controller
{
...
public JsonResult UserConnected()
{
string ip = Request.UserHostAddress;
if (MvcApplication.ConnectedtUsers.ContainsKey(ip))
{
MvcApplication.ConnectedtUsers[ip] = DateTime.Now;
}
else
{
MvcApplication.ConnectedtUsers.Add(ip, DateTime.Now);
}
int connected = MvcApplication.ConnectedtUsers.Where(c => c.Value.AddSeconds(30d) > DateTime.Now).Count();
foreach (string key in MvcApplication.ConnectedtUsers.Where(c => c.Value.AddSeconds(30d) < DateTime.Now).Select(c => c.Key))
{
MvcApplication.ConnectedtUsers.Remove(key);
}
return Json(new { count = connected }, JsonRequestBehavior.AllowGet);
}
}
Finally, on my layout page, added this code which will call my action every 30 seconds and output the result in a span :
<span id="connectedUsers"></span>
<script type="text/javascript">
function PollUsers()
{
$(function() {
$.getJSON("/Commons/UserConnected", function(json){ $('#connectedUsers').text(json.count + " user(s) connected")});
});
}
setInterval(PollUsers, 30000);
</script>
May not be that precise, maybe not that elegant either, but it works. Of course, multiple users from the same IP would count for one user. But it's the best solution I've experimented so far.
you can call a webmethod from javascript on unload body event.

I have two production websites that have similar content. One of these websites needs to be indexed by search engines and the other shouldn't. Is there a way of adding content to the response given to the client using the HttpModule?
In my case, I need the HttpModule to add to the response sent to the when the module is active on that particular web.
You'd probably want to handle the PreRequestHandlerExecute event of the application as it is run just before the IHttpHandler processes the page itself:
public class NoIndexHttpModule : IHttpModule
{
public void Dispose() { }
public void Init(HttpApplication context)
{
context.PreRequestHandlerExecute += AttachNoIndexMeta;
}
private void AttachNoIndexMeta(object sender, EventArgs e)
{
var page = HttpContext.Current.CurrentHandler as Page;
if (page != null && page.Header != null)
{
page.Header.Controls.Add(new LiteralControl("<meta name=\"robots\" value=\"noindex, follow\" />"));
}
}
}
The other way of doing it, is to create your own Stream implementation and apply it through Response.Filters, but that's certainly trickier.
