// Needs #include <CkZip.h>

    CkString strOut;

    CkZip zip;

    bool success;

    //  Any string unlocks the component for the 1st 30-days.
    success = zip.UnlockComponent("Anything for 30-day trial");
    if (success != true) {
        strOut.append(zip.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    success = zip.NewZip("test.zip");
    if (success != true) {
        strOut.append(zip.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    //  Append a directory tree.  The call to AppendFiles does
    //  not read the file contents or append them to the zip
    //  object in memory.  It simply appends references
    //  to the files so that when WriteZip or WriteZipAndClose
    //  is called, the referenced files are streamed and compressed
    //  into the .zip output file.

    bool recurse = true;
    success = zip.AppendFiles("c:/temp/a/*",recurse);
    if (success != true) {
        strOut.append(zip.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    bool success = zip.WriteZipAndClose();
    if (success != true) {
        strOut.append(zip.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    strOut.append("Zip Created!");
    strOut.append("\r\n");


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
