Private Sub btnSendMail_Click() Dim oSmtp As New EASendMailObjLib.Mail oSmtp.LicenseCode = "TryIt" ' Set your sender email address oSmtp.FromAddr = "firstname.lastname@example.org" ' Add recipient email address oSmtp.AddRecipientEx "email@example.com", 0 ' Set email subject oSmtp.Subject = "test HTML email from VB 6.0 with embedded images" Dim cid As String ' Add embedded image and return the unique identifier of the attachment cid = oSmtp.AddInline( "c:\test.gif" ) If cid = "" Then MsgBox "failed add embedded image with error:" & oSmtp.GetLastErrDescription() Exit Sub End If ' Set HTML body format oSmtp.BodyFormat = 1 ' Use the cid as link in the body text oSmtp.BodyText = "<html><body>Hello, this is a embedded <img src=""cid:" & cid & _ """ > picture.</body><html>" ' Your SMTP server address oSmtp.ServerAddr = "smtp.emailarchitect.net" ' User and password for ESMTP authentication, if your server doesn't require ' User authentication, please remove the following codes. oSmtp.UserName = "firstname.lastname@example.org" oSmtp.Password = "testpassword" ' If your smtp server requires SSL connection, please add this line ' oSmtp.SSL_init MsgBox "start to send email ..." If oSmtp.SendMail() = 0 Then MsgBox "email was sent successfully!" Else MsgBox "failed to send email with the following error:" & oSmtp.GetLastErrDescription() End If End Sub
To attach embedded images/pictures, ImportMailEx and ImportHtml methods are strongly recommended. With these methods, you don’t have to specify the ContentID manually. The html source/file html body can be imported to email with embedded pictures automatically.
You can also refer to the htmlmail.* samples in EASendMail Installer. Those samples demonstrate how to build a HTML email editor and send HTML email with attachment or embedded images/pictures.
