In previous section, I introduced how to download email with background service. In this section, I will introduce how to parse email in VB 6.0.
Sections:
After you received the emails to the local folder, we can use the following code to parse the email now. The following code demonstrates how to parse from, to, cc, subject, body text, attachments of all emails file received by previous sample.
Note
Remarks: All of examples in this section are based on first section: A simple VB 6.0 project. To compile and run the following example codes successfully, please click here to learn how to create the test project and add reference to your project.
The following example codes demonstrate how to use EAGetMail POP3 component to parse email sender, to, cc, subject, body text and attachments.
Note
To get the full sample projects, please refer to Samples section.
Option Explicit
Private Sub ParseEmail(ByVal emlFile As String)
Dim oMail As New EAGetMailObjLib.Mail
oMail.LicenseCode = "TryIt"
On Error GoTo ErrorHandle
oMail.LoadFile emlFile, False
' Parse email sender
MsgBox "From: " & oMail.From.Address
Dim addressList As EAGetMailObjLib.AddressCollection
Dim i As Long
Dim addr As EAGetMailObjLib.MailAddress
' Parse email to recipients
Set addressList = oMail.ToList
For i = 0 To addressList.Count - 1
Set addr = addressList.Item(i)
MsgBox "To: " & addr.Address
Next
' Parse email cc
Set addressList = oMail.CcList
For i = 0 To addressList.Count - 1
Set addr = addressList.Item(i)
MsgBox "Cc: " & addr.Address
Next
' Parse email subject
MsgBox "Subject: " & oMail.Subject
' Parse email text body
MsgBox "Text body: " & oMail.TextBody
' Parse email HTML body
MsgBox "Html body: " & oMail.HtmlBody
' Parse attachments
Dim atts As EAGetMailObjLib.AttachmentCollection
Dim att As EAGetMailObjLib.Attachment
Set atts = oMail.AttachmentList
For i = 0 To atts.Count - 1
Set att = atts.Item(i)
MsgBox "Attachment: " & att.name
' Save attachment to local file.
att.SaveAs App.Path & "\inbox\" & att.name, True
Next
Exit Sub
ErrorHandle:
MsgBox Err.Description
End Sub
Private Sub Command1_Click()
Dim curpath As String
Dim mailbox As String
Dim oTools As New EAGetMailObjLib.Tools
' Create a folder named "inbox" under current directory
' to save the email retrieved.
curpath = App.Path
mailbox = curpath & "\inbox"
oTools.CreateFolder mailbox
Dim files
Dim i As Long
' Get all *.eml files in specified folder and parse it one by one.
files = oTools.GetFiles(mailbox & "\*.eml")
For i = LBound(files) To UBound(files)
ParseEmail files(i)
Next
Exit Sub
ErrorHandle:
MsgBox Err.Description
End Sub
TextBody and HtmlBody
Not every email has both text/plain body text and html body text. However, Mail object provides both TextBody and HtmlBody properties smartly. If the email has only text/plain body, then Mail object converts the text/plain body to html body automatically; if the email has only html body, then Mail object converts the html body to text/plain body automatically.

At next section I will introduce how to verify digital signature and decrypt email.
