EmailReadNextHeader (Function)

In french: EmailLitEntêteSuivant

Reads the header of the email found after the current email:

POP3 or IMAP protocol: the Email is stored in the mailbox on the mail server.
via Lotus Notes or Outlook e-mail software: the email received is stored on the local workstation in the Lotus Notes or Outlook inbox.

The various variables in the Email structure (or in the variable of type Email) corresponding to the message header are filled in.

This function is useful when reading the email is linked to the message size for example.

The Email.Out variable is set to True if no email is found.

Reminder Before reading an Email, it is necessary to open a session with the EmailStartSession, EmailStartNotesSession or EmailStartOutlookSession function.

The POP3 protocol can only be used to read emails.

Example

// Lecture du premier email 
EmailReadFirstHeader(IDEmail)
IF Email.Out = False THEN
	// Affiche l'expéditeur et le sujet dans un champ Table
	TableAdd(TABLE_EmailRecus, Email.Sender + TAB + Email.Subject)
	// Lecture de l'email suivant
	EmailReadNextHeader(IDEmail)
END

Remarks

No next email

If no email was found (no next message), the Email.Out variable is set to True. The next call to EmailReadNextHeader will read the header of first incoming message (equivalent to EmailReadFirstHeader).

Initializing the reading of emails

If the reading was not initialized by EmailReadFirstHeader, EmailReadNextHeader is used to read the header of first message.

Outlook messaging

The WLanguage EmailReadxxx functions operate with the Outlook data file (.pst) only. The other data files are not supported.
