Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    CkEmail email = new CkEmail();

    // At this point, a new email object has been instantiated, and it
    // already has a Date header field containing the current date/time.
    System.out.println("Date: " + email.emailDateStr());

    // We can also get the Date header like this:
    System.out.println("Date: " + email.getHeaderField("Date"));

    // Load a .eml into the email object:
    success = email.LoadEml("myEmlFiles/someEmail.eml");
    if (success != true) {
        System.out.println(email.lastErrorText());
        return;
        }

    // Show the Date that was in the .eml
    System.out.println("Date: " + email.emailDateStr());

    // Now the Date header contains whatever was in the .eml
    // Let's update it to the current system date/time..

    CkDateTime dateTime = new CkDateTime();

    dateTime.SetFromCurrentSystemTime();

    success = email.SetDt(dateTime);
    if (success != true) {
        System.out.println(email.lastErrorText());
        return;
        }

    // Now show that the Date is the current system time:
    System.out.println("Date: " + email.emailDateStr());
    System.out.println("Date: " + email.getHeaderField("Date"));
  }
}
