(DataFlex) 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.

Procedure Test
    Handle hoEmail
    Boolean iSuccess
    Variant vDateTime
    Handle hoDateTime
    String sTemp1

    Get Create (RefClass(cComChilkatEmail)) To hoEmail
    If (Not(IsComObjectCreated(hoEmail))) Begin
        Send CreateComObject of hoEmail
    End

    //  At this point, a new email object has been instantiated, and it
    //  already has a Date header field containing the current date/time.
    Get ComEmailDateStr Of hoEmail To sTemp1
    Showln "Date: " sTemp1

    //  We can also get the Date header like this:
    Get ComGetHeaderField Of hoEmail "Date" To sTemp1
    Showln "Date: " sTemp1

    //  Load a .eml into the email object:
    Get ComLoadEml Of hoEmail "myEmlFiles/someEmail.eml" To iSuccess
    If (iSuccess <> True) Begin
        Get ComLastErrorText Of hoEmail To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    //  Show the Date that was in the .eml
    Get ComEmailDateStr Of hoEmail To sTemp1
    Showln "Date: " sTemp1

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

        Get ComLastErrorText Of hoEmail To sTemp1
        Showln sTemp1
        Procedure_Return

    Get ComGetHeaderField Of hoEmail "Date" To sTemp1
    Showln "Date: " sTemp1
