    // Create a string array object with our set of filename patterns
    // to be excluded:
    CkStringArray sa;
    success = sa.Append("*.bak");
    success = sa.Append("*.tmp");

    // Tell the zip object to use these exclusions:
    zip.SetExclusions(sa);

    // Append a directory tree.  The 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,
    // or WriteExe, etc.) is called, the files are compressed
    // and encrypted.
    bool recurse = true;
    success = zip.AppendFiles("/temp/a/*",recurse);

    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());
