数据库高手帮帮我，ADO的问题

[jerry_mouse]

我在一个函数中打开数据库操作：
_ConnectionPtr MyDb;
MyDb.CreateInstance(__uuidof(Connection));
MyDb->Open("DSN=zktest","","",0);

_RecordsetPtr MySet;
MySet.CreateInstance(__uuidof(Recordset));
MySet->Open("SELECT * FROM book_table",MyDb.GetInterfacePtr(),adOpenDynamic,adLockOptimistic,adCmdText);

_variant_t Holder;
while(！MySet->EOF){
Holder=MySet->GetCollect("INDEX_NUM");
if(Holder.vt!=VT_NULL){
m_tabledata.SetTextMatrix(1,1,((char*)_bstr_t(Holder)));
}
MySet->MoveNext();
}


可是while(！MySet->EOF)这句报错：

这是什么错呀？
MySet->Close();
MyDb->Close();

>while(！MySet->EOF)
！是中文？？

[jerry_mouse]

to jiangsheng(蒋晟):
!不是中文。

[supperapplication]

是不是应该是MySet->IsEOF()

[jerry_mouse]

to supperapplication(行星):
没有IsEOF()这个函数。
