    <p>I have a Delphi 6 application that generates E-mails that I send to my Evernote E-mail address, a special E-mail address for sending documents via E-mail so that they are stored automatically into my Evernote account.</p> <p>I have successfully created HTML documents and sent them to my Evernote E-mail address using the Indy 9.x <strong>TIdSMTP</strong> component. I set the <strong>Content-Type</strong> to '<em>text/html</em>'. It works fine as long <em>as I don't add any attachments</em> to the E-mail. As soon as I add an attachment, something about the generated E-mail makes the Evernote web interface interpret the E-mail as <strong>raw HTML</strong>. In other words, I see the raw HTML in the document display area as if I had done "view-source" in a browser, instead of seeing a rendered web page. The E-mail attachments I am adding are an AVI file and a WAV file if that matters. When I do add attachments both of them show up properly at the bottom of the E-mail in the Evernote web display area.</p> <p>To repeat, as soon as I don't add attachments the document shows up as a pretty web page in the Evernote web interface. If I add attachments, I see raw HTML. Can anyone suggest something I can try to fix this problem? I have enclosed the code I use to send the generated document to my Evernote E-mail address below. The variable named <strong>body</strong> contains a fully formatted HTML document.</p> <p><strong>UPDATE</strong>: I sent the E-mail to a non-Evernote E-mail address so I could see the raw E-mail message. I turns out that adding attachments makes TIdSMTP change the Content-Type of the first part of the multi-part E-mail it generates back to 'text/plain' despite the fact I set it to 'text/html' in my code when I create the message. I'm going to have a look at the Indy source and see if I can figure out what is going wrong.</p> <pre><code>function easySendEmail( theIdSmtp : TIdSmtp; destEMailAddress : string; subject : string; body : string; emailServerSettings : TEmailServerSettingsRecord; aryAttachmentFilenames : TDynamicStringArray; connectTimeOut_ms : integer; bUseEHLO : boolean; authLoginType : TAuthenticationType): boolean; var IdMsg: TIdMessage; aryAttachments: TDynamicIdAttachmentArray; i: integer; begin aryAttachments := nil; IdMsg := nil; destEMailAddress := Trim(destEMailAddress); if destEMailAddress = '' then raise Exception.Create('(TframeEmailServerSettings.easySendEmail) The destination E-mail address is empty.'); subject := Trim(subject); if subject = '' then raise Exception.Create('(TframeEmailServerSettings.easySendEmail) The subject line is empty.'); body := Trim(body); if body = '' then raise Exception.Create('(TframeEmailServerSettings.easySendEmail) The message body is empty.'); try with emailServerSettings do begin // Build a test message and send it. IdMsg := TIdMessage.Create(nil); IdMsg.Recipients.EMailAddresses := destEMailAddress; { Most SMTP servers require the sending E-mail address as the user name for the authentication. However, if we encounter one that doesn't work this way then re-using the authentication user name as the From address will not work. } IdMsg.From.Name := APPLICATION_NAME_EVERMAIL; IdMsg.From.Address := user_name; IdMsg.Subject := subject; IdMsg.Body.Text := body; IdMsg.ContentType := 'text/html'; // IdMsg.ContentType := 'text/plain'; theIdSmtp.Host := host; theIdSmtp.Username := user_name; theIdSmtp.Password := password; theIdSmtp.Port := port_number; // Use EHLO method. theIdSmtp.UseEhlo := true; // Login method of authentication. theIdSmtp.AuthenticationType := atLogin; // Add the attachments. // &gt;&gt;&gt; If I comment out the code below the document shows // up as a rendered web page in the Evernote web interface. // If I uncomment it and therefore add attachments, the // document shows up as raw HTML. { if Length(aryAttachmentFilenames) &gt; 0 then begin SetLength(aryAttachments, Length(aryAttachmentFilenames)); for i := Low(aryAttachmentFilenames) to High(aryAttachmentFilenames) do // Add each attachment. aryAttachments[i] := TIdAttachment.Create(IdMsg.MessageParts, aryAttachmentFilenames[i]); end; // if Length(aryAttachmentFilenames) &gt; 0 then } // Connect to the desired SMTP server. N second time-out. theIdSmtp.Connect(connectTimeOut_ms); // Send it. theIdSmtp.Send(IdMsg); // If we got here than the test succeeded. Set the flag // indicating the current settings are valid. Result := true; end; // with mergeEditsWithOriginal do finally theIdSmtp.Disconnect; if Assigned(IdMsg) then IdMsg.Free; end; // try end; </code></pre>

    1. CONo idea what's going on, just a thought: have you tried adding the attachments before setting the content type of the body and setting its contents?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
