的CDaoRecordset ::尋道錯誤

Question

CString str = "something"; 
CDaoDatabase db; 
//db open 
CDaoRecordset rs(&db); 
rs.Open(AFX_DAO_USE_DEFAULT_TYPE,"select * from mydb"); 
COleVariant searched(str); 
BOOL bFound = rs.Seek("=",searched); 

對於這一說法VS2008返回error C2664: 'BOOL CDaoRecordset::Seek(LPCTSTR,COleVariant *,COleVariant *,COleVariant *)' : cannot convert parameter 2 from 'COleVariant' to 'COleVariant *'.

我怎麼能轉換​​的指針？

Answer 1

使用地址運算符 '&'

BOOL bFound = rs.Seek("=",&searched);
