Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

Use ChilkatAx-9.5.0-win32.pkg

Procedure Test
    Boolean iSuccess
    Variant vEmail
    Handle hoEmail
    Handle hoSbHtml
    Handle hoMailman
    String sTemp1

    //  This example requires the Chilkat Email API to have been previously unlocked.
    //  See Unlock Chilkat MailMan for sample code.

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

    //  Tell Chilkat you want the email to be utf-8.
    Set ComCharset Of hoEmail To "utf-8"

    Set ComFrom Of hoEmail To "somebody@gmail.com"
    Get ComAddTo Of hoEmail "Joe" "joe_somebody@gmail.com" To iSuccess
    Set ComSubject Of hoEmail To "This is a test"

    //  Load a utf-8 HTML file that will be the body of this email.
    //  The HTML contains this line to specify the charset:
    // 
    //      <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    // 
    //  The sample HTML is available here:  https://chilkatsoft.com/exampleData/sample_utf8.html
    // 
    Get Create (RefClass(cComChilkatStringBuilder)) To hoSbHtml
    If (Not(IsComObjectCreated(hoSbHtml))) Begin
        Send CreateComObject of hoSbHtml
    End
    Get ComLoadFile Of hoSbHtml "qa_data/html/sample_utf8.html" "utf-8" To iSuccess

    Get ComGetAsString Of hoSbHtml To sTemp1
    Send ComSetHtmlBody To hoEmail sTemp1

    //  If this email was sent as-is, it would look like this:
    Get Create (RefClass(cComChilkatMailMan)) To hoMailman
    If (Not(IsComObjectCreated(hoMailman))) Begin
        Send CreateComObject of hoMailman
    End

vEmail To sTemp1
    Showln sTemp1

    //  The MIME that would be sent is this:
