Sending Email using ASP.NET 2.0 and VB.NET

This tutorial will show you how to send a simple email message using ASP.NET 2.0 and VB.NET

Sending a email 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.

Imports System.Net.Mail

If you're looking for a really good web host, try Server Intellect - we found the setup procedure and control panel, very easy to adapt to and their IT team is awesome!

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.

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Try Dim message As New MailMessage(txtTo.Text, txtFrom.Text, txtSubject.Text, txtBody.Text) Dim emailClient As New SmtpClient(txtSMTPServer.Text) emailClient.Send(message) litStatus.Text = "Message Sent" Catch ex As Exception litStatus.Text = ex.ToString() End Try End Sub

Yes, it is possible to find a good web host. Sometimes it takes a while. After trying several, we went with Server Intellect and have been very happy. They are the most professional, customer service friendly and technically knowledgeable host we've found so far.

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 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>

We moved our web sites to Server Intellect and have found them to be incredibly professional. Their setup is very easy and we were up and running in no time.

The flow for the code behind page is as follows.

Imports System.Net.Mail Partial Class _Default Inherits System.Web.UI.Page Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Try Dim message As New MailMessage(txtTo.Text, txtFrom.Text, txtSubject.Text, txtBody.Text) Dim emailClient As New SmtpClient(txtSMTPServer.Text) emailClient.Send(message) litStatus.Text = "Message Sent" Catch ex As Exception litStatus.Text = ex.ToString() End Try End Sub End Class
