I'm experiencing a to me mysterious error when sending e-mails through a SMTP-server from an ASP.NET web application. I get the famous error "unable to relay for xxx@yyy.zzz". What's mysterious to me is that when I cut and paste the exact same code that sends the e-mail into an usual .NET Windows Forms application, send the e-mail with this application, it all works just fine. This made me think that perhaps the problem is that the ASP.NET application runs as NETWORK SERVICE while the Windows Forms application runs on a domain user account, but it turns out that I have another ASP.NET application sending e-mail through the same SMTP-server running under NETWORK SERVER at the same IIS, and this application does not experience this problem.
I've further tried to send e-mails through the SMTP-server manually by telnet the smtp-server on port 25 and running the SMTP-protocol manually, and it all works fine. The SMTP-server is not configured with any kind of authentication or SSL.
Another mysterious fact is that the ASP.NET application can send e-mails from an adress within the same domain to an e-mail adress within the same domain, but not to any adress outside of the domain. But the Windows Forms application, that uses the exact same code, can send e-mails from any adress to any adress both within AND outside of the domain.
So to summarize:
The ASP.NET application can send
e-mails from addresses within the
domain to adresses within the domain,
but not to addresses outside of the
domain.
A Windows Forms application running
the same code on the same computer
can send e-mails from ANY address to
ANY address.
Another ASP.NET application on the
same IIS running under the same
account (NETWORK SERVICE) can send
e-mails using the same SMTP-server
from ANY adress to ANY adress.
There is no authentication configured
on the SMTP-Server.
Both the ASP.NET application and the
Windows Forms application utilizes
the System.Net.Mail.SmtpClient class
to send a
System.Net.Mail.MailMessage.
The code that sends the e-mail massage is:
private void button1_Click(object sender, EventArgs e)
{
MailMessage mesasge = new MailMessage(txtFrom.Text, txtTo.Text, "Test mail", txtBody.Text);
SmtpClient client = new SmtpClient();
if (!(string.IsNullOrEmpty(txtUserName.Text))) //Is false since txtUserName.Text is empty
client.Credentials = new System.Net.NetworkCredential(txtUserName.Text, txtPassword.Text);
client.EnableSsl = false;
client.Host = txtServer.Text;
client.Port = 25;
try
{
client.Send(mesasge);
}
catch (Exception ex)
{
txtResponse.Text = ex.Message;
}
}
As far as I can understand, this should be a matter of configuration rather than coding issues.
I have some common dlls that are referenced by both a windows service application and a asp.net web application. I don't want to make separate copies of the dlls and I also don't want to put those dlls into GAC. I try to put that service application under the same root folder as the web application so that they can share the same bin folder. I am not quite sure if this will cause any problems? I did find the web application had random session timeout, but not very often. Not sure if it was caused by the shared dlls.
View 1 RepliesI have a simple windows form app that I need to get the file path for. I am placing a config file in the same directory and I need to be able to get the path to that file.
I have used
Application.CommonAppDataPath
but that returns the path with 1.0.0.0 at the end.
and
Applicaiton.StartupPath
but that returns the path with indebug at the end
Is there anyway to get the path to just the main file directory without anything appended to the end?
why is it that the exact same codes that i use to create a Windows application, which is able to work, does not work on a Web application? i created a windows application using c# and socket programming language. i will be connected to a remote server and through the windows application, and i will be able to send the "byte[] msg" to the server and activate the LED lightbulbs attached to the remote server. that exact same codes works well on the Windows application. however, when i create another Web application using the same exact codes, i does not have any error yet i am not able to activate the LED lightbulbs attached to it. is it that through the web or internet explorer i am not able to send the "byte[] msg" correctly? or that i sld modify "byte[] msg" to suit the web usage? or any other reasons?
View 7 RepliesI have a web application that dynamically loads assemblies based on database configuration entries to perform certain actions (dynamic plugin style architecture).The calls to the objects are in a Factory Pattern implementation, and the object is cached (in a static dictionary<> within the Factory) as the calls can be made many thousands of times in a minute.The calls to this factory are made from both the main web application and a number of webservices, some in different assemblies/projects.When I need to update one of these DLLs, I have to recycle IIS to get the DLL released.As this has an impact on another application on the server, I wanted to know if there was a way I could release the DLL without restarting IIS?

Rightnow I'm saving the values in an xml file and fetch the values in the windows application.But this is not practical when creating xml files with random numbers(Scan125.xml,Scan7867.xml,etc).

View 1 RepliesI have a separate environment for development. On my production server, where we mostly host web applications, we deploy the precompiled version of the web project. While doing development I work on three projects. One is the WCF Service. Two, is the class library project. This library has classes which makes calls on the WCF service. And the third, is a web project which consumes the class library.
The last two projects come under one VS solution. I host the wcf service in the development environment. This service is added as service reference to my class library. I am unable to visualize what will happen once I add the DLL (viz output of the class library project) to my web project, and, the web project has to be deployed. At the time of deployment I have to change the service reference (the url of the svc file will change as it has to point to the production wcf service). How to go about this? What must I take care when adding the dll to the web project?

View 4 RepliesI've noticed as my website gets bigger and bigger, the time my laptop takes to display my page is much longer then say a new projects with minimal references. I think there are two variables at play that affect ASP.NET warm-up time:
The quantity of external references The time it takes for a worker process to new() up each instance per worker process Additional time for the WCF objects as the ServiceHost may be in an external DLL First, are those the correct variables to take into account when considering ASP.NET startup time? Next, it appears that web.config may dispatch other objects for use with certain filetypes (*.svc, *.aspx, Windows Identity Foundation (WIF), etc. ). This too may cause delays in ASP.NET.
Last, my project is created as a "web project" not a "web site". Not sure if this has an impact. Is my theory full of holes, or is there something I can do to make development on a old laptop any better?
What are the different ways in which a web application can communicate to a windows application? I have heard that activex control events can be handled in javascript to achieve this.
Does WCF or any new technology provide a better implementation for this?
Can the publish/subscribe architecture be used here?

When I open "New Project" in Visual Web Developer Express, I see an option to create a new ASP.NET MVC 3 Web Application, but not a ASP.NET MVC 3 Empty Web Application.
There is the option to create a ASP.NET MVC 2 Empty Web Application though.
Any particular reason for this?
