Qt，Excel如何使用Find与FindNext

QVariant nextStart;
QAxObject * find = RangeCells->querySubObject("Find(Qstring)",str2qstr(cstrKey));

int nCol = find->property("Column").toInt();
int nRow = find->property("Row").toInt();

QAxObject * findNext = NULL;
int i = 0;
while (find != findNext)
{
    findNext = RangeCells->querySubObject("FindNext()");
    int nFindNextRow = findNext->property("Row").toInt();
    qDebug()<<i<<" Row ="<<nFindNextRow;
    i++;
}

findNext的功能已经实现，现在遗留问题是，如何使用find采用whole匹配方式进行匹配
