MailClient.GetMailInfos Method


Retrieves all emails' information on mail server.

[Visual Basic 6.0]
Public Function GetMailInfoList( _
) As  MailInfoCollection
[Visual C++]
public: HRESULT GetMailInfoList(
IMailInfoCollection* pVal
);

Return Value

A MailInfo array presenting the emails list on the server.

Remarks

By default, GetMailInfoList method returns all emails in "INBOX". You can use SelectFolder method to retrieve email list in selected folder.

GetMailInfosParam property can set some filters for returned email list on server.

For example, you can use GetMailInfosParam property to retrieve only unread/new email(s) from server, then use MarkAsRead method to mark the email as read to prevent retrieving the same email again.

Example

[Visual Basic 6.0, VBScript, Visual C++, Delphi] The following example demonstrates how to receive email with EAGetMail POP3 & IMAP ActiveX Object, but it doesn't demonstrates the events and mail parsing usage. To get the full samples of EAGetMail, please refer to Samples section.
