#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.

    bool success;

    // Create a text/plain part.
    CkMime ptMime;
    ptMime.SetBodyFromPlainText("This is the plain text body");
    strOut.append(ptMime.getMime());
    strOut.append("\r\n");
    strOut.append("****");
    strOut.append("\r\n");

    // The ptMime contains:
    // ---------------------------------------
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // ---------------------------------------

    // Start with an empty MIME object...
    CkMime topLevelMime;

    // Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
    topLevelMime.NewMultipartMixed();

    // Append the ptMime as a child.
    topLevelMime.AppendPart(ptMime);
    strOut.append(topLevelMime.getMime());
    strOut.append("\r\n");
    strOut.append("****");
    strOut.append("\r\n");

    // The topLevelMime contains:
    // --------------------------
    // 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
    // 
    // 	--------------010907090104040508040404
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // 	--------------010907090104040508040404--
    // 

    // IMPORTANT: A copy of the MIME passed in AppendPart is appended.
    // Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
    // For example:
    ptMime.SetBody("this is the new plain text body.");
    // topLevelMime is unchanged.
    strOut.append(topLevelMime.getMime());
    strOut.append("\r\n");
    strOut.append("****");
    strOut.append("\r\n");

    // To change the content in topLevelMime, we must get the text/plain part.
    // For example:
    CkMime *ptMime2 = topLevelMime.GetPart(0);
    ptMime2->SetBody("this is the new plain text body.");
    delete ptMime2;
    // Now topLevelMime is changed.
    strOut.append(topLevelMime.getMime());
    strOut.append("\r\n");
