Using Visual Studio 2010 Web Developer Express (vb.net code) with SqlDataSource to SQL Server 2008.
I am developing an email form to my users to send email to vendors with an attachment. The aspx page is quite simple -- 2 dropdownlists, a fileupload control, and a send email button. They select their store (which populates the "From" address of the email). They select the Vendor (which populates the "To" address of the email). Then they browse for the file attachment and click "send email"
I just can't get outside emails to send. I do not get any error messages in the web page. If I change the email1 and email2 in SQL Server Vendor table to an email address (mine) within the domain I get the emails. However when I change to a test hotmail, yahoo, or gmail accounts the emails never get there. I have absolutely no confidence that my programming is correct so before I go to the IT Manager again I really need to verify I am not missing something on my end. We did make a change on the exchange server to allow anonymous email from my webserver and still didn't work.
Here is my webconfig file:

Here is my code-behind:

Here is my aspx page:

I have been playing around with the programming for 2 days making 1 change at a time then testing to see if external email is sending. I'm going quite crazy at this point ...
I've put in breakpoints and debugged. Below is the output from the latest test. I have concerns about the clientDomain being "SQLSVR" which is my webserver name, our domain is "chuckanddons.com". As well as the line "Domain" that is blank " " under NetworkCredential. Also the line TargetName "SMTPSVC/exchangesvr"

getting the above error when sending mail from asp.net 2.0
I've built several websites on my local machine and have successfully tested sending mail from within the application, but suddenly the mail won't go anywhere! I have a try-catch routine, and I'm getting the message that the mail has been sent successfully but it's not going anywhere. This is the code that I've used in a test page - the html page has a button and a textbox and nothing else. I've imported the system.net.mail namespace.

I'm getting the 'Email Successfully Sent' Message but I'm not receiving the email. I don't think I've changed any settings to stop the emails from going.

This code is working fine in my local system but when i upload it on server then it gives this error. From the last 1 year it was working fine but from last few days it gives me above said error, please suggest me is there any authentication required to send mail from server (my hosting plan is with 1and1.com)
I am building an ASP.NET intranet application. I am trying to get the host name of the client machine. I have started off by using System.Net.Dns.GetHostName(); but this just seems to return the hostname of the server running the website through IIS. Am I using the wrong method or am I using this one incorrectly?

I have a Windows 7 machine hosting a Windows 7 virtual machine. I am developing a web application using visual studio 2010 on my host machine. I want to run the application in debug mode and access my localhost server from a browser on the virtual machine. (The purpose of this is to be able to debug an application that uses Windows Authentication using different users without having to log off and on for different users on my host machine...)
I am using a bridged connection for the virtual machine. I googled how to solve this problem and most of the threads that I found said that if I was using a bridged connection, I could access the server on the host machine by just entering the IP address of my host machine into the url in the browser of the virtual machine. I have tried some different urls using the IP but none of them have worked.
As an example, suppose I run my web application in visual studio on my host machine and its url is
http://localhost:62789/MyPage.aspx
Assume also that I ran ipconfig in CommandPrompt on my host machine and found out that the IP address for my host machine is xxx.xxx.xxx.x. What url should I enter on the virtual machine to access my web application?
EDIT:
I set up IIS to host the web project. After that, I just added the following line (xxx.xxx.xxx.xxx is my IP) to my hosts file and I was able to access the website from the virtual machine:
xxx.xxx.xxx.xxx MyWebsite.net
I also had to edit my firewall settings.
I have to host an asp.net that user can access that website something like http://111.11.11.11/myapp/homepage.aspx. ( my ip address will be 111.11.11.11). All I have local IIS installed. I want that if any user clicks on the link. He should be able to access that web application.
View 9 RepliesWhat could potentially stop an AJAX call from working on the host server, when it works fine on the local host? I tried returning an error from the AJAX call, but all I get is 'undefined'. I don't think the actual page method is being called since no information is added in my log (and I've explicitly added a call).

how to find SMTP port and host name ? I used default one its gives me error.No connection could be made because the target machine actively refused it.
My application needs to send an email once the user has been registered. It should be able to send the new credentials, and a URL from the mail body. Every thing is working fine but I have few specifications that I am not able to reach.
1. I have multiple lines and I am not able to send a new line character from the mail body.
2. I should send them the link of my application which should be done using javascript (i guess) and i can not do it as well.

I am dynamically generating a number of different types of files based upon a GridView in ASP.NET - an Excel spreadsheet and a HTML file. I am doing so using this code (this is just for the Excel spreadsheet):
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=InvoiceSummary" + Request.QueryString["id"] + ".xls");
Response.Charset = "";
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
contents.RenderControl(htmlWrite);
//GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
I would like to give users the options of emailing the generated file as an attachment to either an email address they specify or one linked with their account on the database. But I don't want the user to have to save the file, then attach it in a form - I'd like to automatically attach the generated file. Is this possible, and how easy is it?
Of course, I'll be using the System.Net.Mail class to send mail...if it's possible anyway!
I want to send a mail with embeded image in ASP.NET
How can i do that?
I use a function that sends emails to some users.
I use the following code to send delivery notification failure messages to the sender email
when a message fails to reach the user.
I use the following code.
System.Web.Mail.MailMessage messagetest = new System.Web.Mail.MailMessage();
messagetest.Headers.Add("Disposition-Notification-To", txtFrom.Text);
now I want to enable the sender to receive a Delivered receipt message when the mail arrives successfully.
how can this be done ?
