Why Application_PostAuthenticateRequest and Application_AuthenticateRequest events happen twice ? When I put a breakpoint in their code I see that when I run the application they are called twice ? Can someone tell me why they have to be called twice ? Illustrating their position in the asp.net's events flowchart will be helpful . Help me please .

Basically, when a web page is processed, the application will get through a couple of events starting with the BeginRequest, AuthenticateRequest, PostAuthenticateRequest ..... For example when you first access a restricted web page, say Home.aspx, you can see that these two events occur, and because you are not logged on yet you will redirected to the Login page, and as a result of this the two events get fired again. And then if in the Login page there are a couple of links requesting for the resources at the server side and they are handled by the ASP.NET engine like the WebResource.axd, you'll see that these events again occurs. For more information on the events of the Application, you can see the HttpApplication[^]

Hi,
I have created a DotNetNuke website and I want to host it on my Windows Server 2003. I have given a public IP address to my server and setup asp.net applications on the IIS (version 6).
I can access the DNN website locally from my machine but I cant access some pages from another machine using the IP address. I can access the html pages or images from another machine but I cant view the .aspx pages. I think the pages that are linked to the database cannot be viewed.
I would really appreciate if someone can help me with setting up a DNN website on my web hosting server.
Thanks.

You can use child pop up window to do the task and on closing of the child window you can refresh the parent page. Check the viewstate if you are loosing the data in the postbacks.

thanks for the reply goofy, found out what it was.
I initially added the button through vs2005 which, set the id of the button to "submit", which interfered with the autopostback code

You want to do it on server side or client side?
BTW by writing the question three times doesn't ensure that the question will be answered early.

I have built a web application using Deklarit objects as the Data Abstraction Layer. It works fine on development server but when I upload to my shared host I get SecurityExceptions like the following:
[SecurityException: That assembly does not allow partially trusted callers.]
Deklarit.Data.DataStore.GetReadWriteConnection() +0
Deklarit.Data.DataStore.GetReadWriteConnection(IDbTransaction currentTransaction) +96
WebShopData.DownloadDataAdapter.Update(DataSet dataSet) +69

System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +154
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64
Which assembly is it talking about, DeklaritLibrary.dll, WebShopData.dll or the Enterprise Library dll's?
I have strong named my Deklarit generated assembly and added the AllowPartiallyTrustedCallers attribute to the assembly. The problem only occurs on write to the database, read connection is working fine.
For those not familiar, I am using Deklarit 4.0 and the generated assembly uses Micrososft Enterperise Library which I have also recompiled with the AllowPartiallyTrustedCallers attribute on the Microsoft.Practices.EnterpriseLibrary.Common.dll, Microsoft.Practices.EnterpriseLibrary.Configuration.dll & Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.dll. The host is a shared host and they do not support full trust and I cannot override this setting in web.config.
I have trawled Google and almost everywhere else and I cannot find a simple explanation of how to overcome this problem.
Can anyone please help, it is driving me nuts and consuming alot of time to get nowhere?
Kind regards,
Maurice Moore

SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);<br />
<br />
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;<br />
smtp.EnableSsl = true;<br />
smtp.UseDefaultCredentials = false;<br />

<br />
MailMessage message = new MailMessage();<br />
message.Subject = "etc etc etc";<br />
message.Body = "etc etc etc";<br />
<br />
message.From = new MailAddress("MyGmail@gmail.com");<br />
message.To.Add(new MailAddress("MyGmail@gmail.com"));
<br />
smtp.Send(message);
In MailMessage.To, I place myself mail, and works very fine when I receive feedbacks in the site. But I wish use the same code to send e-mail to another persons, (like password reminders). The code works fine, none exceptios are throwed but the mail is not received!!! What's wrong? Someone can help me?
