The following figure (Figure 1) shows a properly configured collection of input fields in use:įigure 1: The Demonstration Application in UseĪ quick review of the code will reveal that there is little going on there. To maintain the simplicity of the project, little in the way of error handling has been included. The application is simple, but could easily be improved by validating each of the required fields through the use of regular expressions or by at least validating that the text associated with each of the text boxes is not an empty string.

The main form is a Windows application form, and it contains a few controls necessary to capture the fields needed to properly form the message. Within the project, you will find one main class: frmMain.vb. In order to begin, unzip the downloaded files and open the project provided. The source code provided includes a relatively good list of carriers to simplify the task of connecting with a cell phone, and the task itself is really no more difficult than sending an email message through a desktop or web based application. RemarksThis article describes a simple way to send text messages to a cellular phone from within a VB.NET desktop application. The message could not be delivered to two or more of the recipients in To, CC, or Bcc. A SmtpFailedRecipientsException contains a list of the recipients that were rejected. When sending email using Send to multiple recipients and the SMTP server accepts some recipients as valid and rejects others, Send sends email to the accepted recipients and then a SmtpFailedRecipientsException is thrown (or a SmtpFailedRecipientException if only one recipient is rejected). The SmtpException can also contain an inner exception that indicates the reason the operation failed.
If you receive an SmtpException exception, check the StatusCode property to find the reason the operation failed. To specify credentials, use the UseDefaultCredentials or Credentials properties. If the SMTP host requires credentials, you must set them before calling this method.
You cannot call this method if there is a message being sent asynchronously.
You can specify a time-out value using the Timeout property to ensure that the method returns after a specified amount of time elapses.īefore calling this method, the Host and Port properties must be set either through the configuration files by setting the relevant properties, or by passing this information into the SmtpClient(String, Int32) constructor. This method blocks while the email is transmitted. SmtpClient client = new SmtpClient(server) Ĭonsole.WriteLine("Exception caught in CreateTestMessage2(): ", Message.Body = this new feature, you can send an email message from an application very easily."
Message.Subject = "Using the new SMTP client." String to = from = message = new MailMessage(from, to) Public static void CreateTestMessage2(string server) to authenticate before it will send email on the client's behalf. Credentials are necessary if the server requires the client SmtpClient^ client = gcnew SmtpClient( server ) Message->Body = L"Using this new feature, you can send an email message from an application very easily." Message->Subject = L"Using the new SMTP client." String^ to = from = message = gcnew MailMessage( from,to ) static void CreateTestMessage2( String^ server ) The following code example demonstrates using this method.
