#include <CkMime.h>

void ChilkatSample(void)
    {
    CkString strOut;

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

    CkMime mime;

    // The contents of this MIME file are shown below, 
    // and is also available at https://www.chilkatsoft.com/sampleMime.txt
    bool success = mime.LoadMimeFile("qa_data/mime/sampleMime.txt");
    if (success != true) {
        strOut.append(mime.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    // The MIME used in this example has the following nested structure
    // 
    // multipart/alternative
    //     text/plain
    //     multipart/related
    //         text/html
    //         image/jpeg
    // 

    // This example will save each of the non-multipart parts.
    // It will create three files -- a .txt, .html, and .jpg.

    // Save the body of the text/plain part.
    CkMime *pTxt = mime.GetPart(0);
    pTxt->SaveBody("qa_output/textPart.txt");
    delete pTxt;

    // Save the HTML part.
    CkMime *mpRelated = mime.GetPart(1);
    CkMime *pHtml = mpRelated->GetPart(0);
    pHtml->SaveBody("qa_output/htmlPart.html");
    delete pHtml;

    // Save the JPG binary data.  (The data is automatically base64 decoded prior to saving.)
    CkMime *pJpg = mpRelated->GetPart(1);
    pJpg->SaveBody("qa_output/jpgPart.jpg");
    delete pJpg;

    delete mpRelated;
