The wwSMTP class allows sending emails from Visual FoxPro applications through standard SMTP/ESMTP mail servers. In order to use this class you will need to have an SMTP mail server address from your or your users ISP or a company server.
Two modes: Classic or wwSmpt (.NET)
The wwSmtp class comes in two flavors:
.NET Mail Mode (nMailMode = 0)
Uses .NET and wwDotNetBridge to send emails. The .NET component provides additional features such as SSL/TSL encrypted content, embedded rich content resources like images and the ability to send multiple emails on a single mail connection. The .NET interface uses the native SmtpClient in .NET to abstract mail sending operations which are exposed through wwDotNetBridge.Classic wwIPStuff Mode (nMailMode = 2)
Uses classic wwIPStuff behavior using a plain Win32 dll that doesn't need to be registered nor require any special runtimes. Only supports SendMail and SendMailAsync methods - the Connect/SendMessage/Close methods that allow for single connection multi-recipient sends are not available. This is the default behavior.
nMailMode can be set via property:
loSmtp = CREATEOBJECT("wwSmtp")
loSmtp.nMailMode = 0 && .NET mode
or via Init parameter:
loSmtp = CREATEOBJECT("wwSmtp",0)
wwSmtp
Remarks
Running wwSmtp off a Network
If you're running wwSmtp in .NET mode and from a network location please take a look at .NET security configuration required that might affect operation of the wwSmtp class.

Class Members
Member | Description | |
---|---|---|
AddAlternateView |
Allows adding an alternate view of the message that provides richer content. For example you may configure the main message as plain text and the alternate view as html including embedded images that are stored as part of the message. o.AddAlternateView(loAlternateView) |
|
AddAttachment |
Adds one or more file attachments to the mail message. o.AddAttachment(lcFileName, lcContentType) |

Close |
Closes an SMTP connection opened with Connect o.Close() |
|
Connect |
wwSmtp :: Connect o.Connect() |
|
Dispose |
Cleans up this object instance by removing the .NET SMTP reference and wwDotNetBridge instance. Can be called explicitly, but is also called internally off the object's Destroy() event. o.Dispose() |
|
SendMail |
This method allows sending of SMTP emails which is the most common Email interface for the Internet. This method requires that you have access to an SMTP mail server. o.SendMail() |
|
SendMailAsync |
This method functions identical to the SendMail method of this component, except that the message is sent asynchronously in the background while the call to this function immediately returns to FoxPro. o.SendMailAsync() |
|
SendMessage |
Sends a single message to an SMTP server, but allows multiple messages to be sent on a single open SMTP connection. Requires that you call Connect() before SendMessage() calls and Close() or Dispose() after. o.SendMessage(lcRecipient, lcCC, lcBcc) |
