SMTP server is the problem, not your code. Make sure that relay is enable on SMTP server for the IP address of computer that send mail.

Hi there,
Sending a email with an attachment using ASP.NET 2.0 and VB.NET is actually very simple.
First, you will need to import the System.Net.Mail namespace.
The System.Net.Mail namespace contains the SmtpClient and MailMessage Classes that we need in order to send the email and the message attachment.
| Imports System.Net.Mail |
We use the btnSubmit_Click event to do the work.
We then call the emailClient.Send to send the message using the variables from our ASP.NET coded page.
The txtAttachmentPath.Text Texbox provides the path to the file to attach to the email message.
| Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Try
End Sub Dim SendFrom As MailAddress = New MailAddress(txtFrom.Text) Catch ex As Exception
Dim SendTo As MailAddress = New MailAddress(txtTo.Text) Dim MyMessage As MailMessage = New MailMessage(SendFrom, SendTo) MyMessage.Subject = txtSubject.Text MyMessage.Body = txtBody.Text Dim attachFile As New Attachment(txtAttachmentPath.Text) MyMessage.Attachments.Add(attachFile) Dim emailClient As New SmtpClient(txtSMTPServer.Text) emailClient.Send(MyMessage) litStatus.Text = "Message Sent" litStatus.Text = ex.ToString() End Try |
The front end .aspx page looks something like this:
| <table width="600" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#cccccc"> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1"> To</td> <td bgcolor="#FFFFFF"><asp:TextBox ID="txtTo" runat="server" Columns="50"></asp:TextBox> </td> </tr> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1"> From</td> <td bgcolor="#FFFFFF"><asp:TextBox ID="txtFrom" runat="server" Columns="50"></asp:TextBox> </td> </tr> <tr> <td align="right" bgcolor="#eeeeee" class="header1"> SMTP Server</td> <td bgcolor="#FFFFFF"><asp:TextBox ID="txtSMTPServer" runat="server" Columns="50"></asp:TextBox></td> </tr> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1"> Subject</td> <td bgcolor="#FFFFFF"><asp:TextBox ID="txtSubject" runat="server" Columns="50"></asp:TextBox></td> </tr> <tr> <td align="right" bgcolor="#eeeeee" class="header1"> Attachment</td> <td bgcolor="#FFFFFF"> <asp:TextBox ID="txtAttachmentPath" runat="server" Columns="50"></asp:TextBox></td> </tr> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1"> Body</td> <td bgcolor="#FFFFFF"><asp:TextBox ID="txtBody" runat="server" Columns="40" TextMode="MultiLine"></asp:TextBox></td> </tr> <tr> <td align="right" bgcolor="#eeeeee" class="header1">Action</td> <td bgcolor="#FFFFFF"><asp:Button ID="btnSubmit" runat="server" Text="Send Email" OnClick="btnSubmit_Click" /></td> </tr> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1">Status</td> <td bgcolor="#FFFFFF" class="basix"><asp:Literal ID="litStatus" runat="server"></asp:Literal></td> </tr> </table> |
The flow for the code behind page is as follows.
| Imports System.Net.Mail Partial Class _Default Inherits System.Web.UI.Page End Class Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Try
End SubDim SendFrom As MailAddress = New MailAddress(txtFrom.Text) Catch ex As Exception
Dim SendTo As MailAddress = New MailAddress(txtTo.Text) Dim MyMessage As MailMessage = New MailMessage(SendFrom, SendTo) MyMessage.Subject = txtSubject.Text MyMessage.Body = txtBody.Text Dim attachFile As New Attachment(txtAttachmentPath.Text) MyMessage.Attachments.Add(attachFile) Dim emailClient As New SmtpClient(txtSMTPServer.Text) emailClient.Send(MyMessage) litStatus.Text = "Message Sent" litStatus.Text = ex.ToString() End Try |

use VB.NET and C#.NET code in the same C#.NET project
All-- Here is a sample that is "off the beaten path", (at least for me). Is it possible, in an ASP.NET application, using the code-behind page building technique, to have both pages written in VB.NET and pages written C#.NET?At http://www.WebLogicArts.com/DemoList.aspx there is a sample that shows that, (contrary to popular belief), it IS possible to mix ASP.NET pages built with C#.NET with ASP.NET pages built with VB.NET in the same VS.NET 2003 project. Note that this is just a "fun" sample to see if it can be done and I do not recommend this practice as a "standard" way of developing. The trick is to use the "Src" attribute of the @Page directive. Check out the link if you are inclined. You are welcome to download the code if you are interested further, found at the same link. (Note that the reason that I looked for a way to do this is because I wanted to have the option to include some VB.NET-based demos at my site. Since my site is a C#.NET ASP.NET, I was told that there was no want to do this. Therefore, I looked for a workaround and just happened to find one.) Enjoy (and then get back to work!) http://www.NetBrainer.com you are right !!!mixing languages could cause unknow and uncontrolled problems !!! if a developer has to mix ....the practical way is to create a new project with different language and what will be absolutely fine !!!thanks mkamoski for raising this issue !!Fadil Alnassar www.fadilalnassar.com | FREE Nodil Tab Controlhttp://www.mefranchisi...

use VB.NET and C#.NET code in the same C#.NET project
All-- Here is a sample that is "off the beaten path", (at least for me). Is it possible, in an ASP.NET application, using the code-behind page building technique, to have both pages written in VB.NET and pages written C#.NET?At http://www.WebLogicArts.com/DemoList.aspx there is a sample that shows that, (contrary to popular belief), it IS possible to mix ASP.NET pages built with C#.NET with ASP.NET pages built with VB.NET in the same VS.NET 2003 project. Note that this is just a "fun" sample to see if it can be done and I do not recommend this practice as a "standard" way of developing. The trick is to use the "Src" attribute of the @Page directive. Check out the link if you are inclined. You are welcome to download the code if you are interested further, found at the same link. (Note that the reason that I looked for a way to do this is because I wanted to have the option to include some VB.NET-based demos at my site. Since my site is a C#.NET ASP.NET, I was told that there was no want to do this. Therefore, I looked for a workaround and just happened to find one.) Enjoy (and then get back to work!) http://www.NetBrainer.com you are right !!!mixing languages could cause unknow and uncontrolled problems !!! if a developer has to mix ....the practical way is to create a new project with different language and what will be absolutely fine !!!thanks mkamoski for raising this issue !!Fadil Alnassar www.fadilalnassar.com | FREE Nodil Tab Controlhttp://www.mefranchisi...
