    {
    BOOL success;
    HCkMimeW ptMime;
    HCkMimeW topLevelMime;
    HCkMimeW ptMime2;

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

    // Create a text/plain part.
    ptMime = CkMimeW_Create();
    CkMimeW_SetBodyFromPlainText(ptMime,L"This is the plain text body");
    wprintf(L"%s\n",CkMimeW_getMime(ptMime));
    wprintf(L"****\n");

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

    // Start with an empty MIME object...
    topLevelMime = CkMimeW_Create();

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

    // Append the ptMime as a child.
    CkMimeW_AppendPart(topLevelMime,ptMime);
    wprintf(L"%s\n",CkMimeW_getMime(topLevelMime));
    wprintf(L"****\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:
    CkMimeW_SetBody(ptMime,L"this is the new plain text body.");
    // topLevelMime is unchanged.
    wprintf(L"%s\n",CkMimeW_getMime(topLevelMime));
    wprintf(L"****\n");

    // To change the content in topLevelMime, we must get the text/plain part.
    // For example:
    ptMime2 = CkMimeW_GetPart(topLevelMime,0);
    CkMimeW_SetBody(ptMime2,L"this is the new plain text body.");
    CkMimeW_Dispose(ptMime2);
    // Now topLevelMime is changed.
    wprintf(L"%s\n",CkMimeW_getMime(topLevelMime));


    CkMimeW_Dispose(ptMime);
    CkMimeW_Dispose(topLevelMime);
