Decoding Attachments as Files

When getting mail from a POP server, attachments are decoded in one of two ways:

Set UseMemoryStreams to false and attachments are decoded and stored as files.
Set UseMemoryStreams to true and attachments are decoded and stored as MemoryStreams.

This value defaults to false as attachments can be quite large, sometimes even exceeding the memory capacity.

To get all messages and decode attachments and store them as files.

Add the Pop component to a new form.
Import the namespace of the component you would like to use using "Using" (C#) or "Imports" (VB.NET). Place the following code at the top of your file.
C# Copy Code
using Dart.PowerTCP.Mail;
Visual Basic Copy Code
Imports Dart.PowerTCP.Mail
Add a button to the form.

C#	Copy Code
using Dart.PowerTCP.Mail;

Visual Basic	Copy Code
Imports Dart.PowerTCP.Mail

Set the properties required to properly get all messages from the server. Place the following code in the Click event of the button added to the form in step 3.

C#	Copy Code
// Be sure the Pop component is configured to automatically retrieve messages. pop1.AutoGet = MessageSection.Complete;

Visual Basic	Copy Code
' Be sure the Pop component is configured to automatically retrieve messages. Pop1.AutoGet = Complete

Login to the server, all messages will be automatically retrieved. After login successfully occurs, logout will automatically occur (since Pop.AutoLogout = true). Place this code directly after the code from step 5.
C# Copy Code
// Login to the POP server. pop1.Login("mail.myserver.com", "test", "pass");
Visual Basic Copy Code
' Login to the POP server. Pop1.Login("mail.myserver.com", "test", "pass")

C#	Copy Code
// Login to the POP server. pop1.Login("mail.myserver.com", "test", "pass");

Visual Basic	Copy Code
' Login to the POP server. Pop1.Login("mail.myserver.com", "test", "pass")

At this point, all messages have been retrieved, allowing full access to all parts of the message, including attachments. For this example, the next step is to save all of the attachments for all of the messages. The following example demonstrates saving all attachments for all messages.

C#	Copy Code
// Save attachments for all messages. foreach(Dart.PowerTCP.PopMessage msg in pop1.Messages) { foreach(Dart.PowerTCP.AttachmentStream att in msg.Message.Attachments) { string filename = "C:\\temp\\" + att.FileName; att.Save(filename, true); } }

Copy Code

// Save attachments for all messages.
foreach(Dart.PowerTCP.PopMessage msg in pop1.Messages)
{
   foreach(Dart.PowerTCP.AttachmentStream att in msg.Message.Attachments)
   {
      string filename = "C:\\temp\\" + att.FileName;
      att.Save(filename, true);
   }
}

Visual Basic	Copy Code
' Save attachments for all messages. Dim msg As PopMessage For Each msg In Pop1.Messages Dim att As AttachmentStream For Each att In msg.Message.Attachments Dim filename As String = "C:\temp\" & att.FileName att.Save(filename, true) Next Next

Visual Basic

Copy Code

' Save attachments for all messages.
Dim msg As PopMessage
For Each msg In Pop1.Messages
   Dim att As AttachmentStream
   For Each att In msg.Message.Attachments
      Dim filename As String = "C:\temp\" & att.FileName
      att.Save(filename, true)
   Next
Next

Compile and run the application. If any messages contained attachments, they will be found in the specified directory ("C:\Temp").
