#include <CkEmail.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkEmail email;

    email.put_Subject("test");
    email.AddTo("Chilkat","support@chilkatsoft.com");
    email.put_From("Matt <matt@example.com>");
    email.put_Body("This is a simple plain-text body.");

    success = email.AddFileAttachment2("qa_data/1.HPM","application/x-hprimnet");
    if (success == false) {
        std::cout << email.lastErrorText() << "\r\n";
        return;
    }

    //  Add a "ContentDescription: HPM/3.0" in the attachment's sub-header.
    //  The 1st attachment is at index 0.
    email.AddAttachmentHeader(0,"Content-Description","HPM/3.0");

    //  Show the email MIME:
    std::cout << email.getMime() << "\r\n";

    //  This is the output:
