Load an Email from MIME in a StringBuilder

Demonstrates the Chilkat Email.SetFromMimeSb method, which loads an email from the MIME text stored in a StringBuilder object. On success, it replaces the entire current email. This example serializes one email into a StringBuilder with GetMimeSb, then reconstructs it in a second object.

Background: This is the StringBuilder counterpart to SetFromMimeText. When the MIME already lives in a StringBuilder — perhaps assembled or edited there — passing it directly avoids converting to an intermediate string, which is more efficient for large messages.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

//  Demonstrates the SetFromMimeSb method, which loads an email from MIME text stored in a
//  StringBuilder object.  On success, it replaces the entire current email.

//  Build a source email and get its MIME into a StringBuilder.
var source = new CkEmail();
source.Subject = "Source message";
source.From = "alice@example.com";
source.Body = "Hello from a StringBuilder.";
var sbMime = new CkStringBuilder();
source.GetMimeSb(sbMime);

//  Load a new email object from the StringBuilder MIME.
var email = new CkEmail();

success = email.SetFromMimeSb(sbMime);
if (success == false) {
    console.log(email.LastErrorText);
    return true;
}

console.log("Loaded subject: " + email.Subject);
