内存泄露,大家帮帮我啊

泄露在BaseDbProxy.cpp中,只有一个new，哭死了

没仔细看代码，你这句m_pDbCon=new CLCDbConnection();对应的delete呢？

[WizardK]

Close()里"m_pDbCon = NULL"前要"delete m_pDbCon"

[pioneer_public]

m_pDbCon->Release();
是释放的吗?

[AndonVC]

m_pDbCon->Release();中已经delete this了啊

//如下
void CLCDbConnection::Release()
{
delete this;
}

to : WizardK()
还是不行啊

to:pioneer_public()
是的,代码在上面

[AndonVC]

析构函数也有
CLCDbConnection::~CLCDbConnection(void)
{
if(m_Conn!=NULL)
{
delete m_Conn;
m_Conn=NULL;
}
}

[zhangyq73]

m_pDbCon->Release()中并没有delete. new和delete一定要配对,在析构函数中直接delete,不用判断.

[AndonVC]

能说清楚一点吗

[zdleek]

没有仔细看楼主的代码
如果你确认delete被正确地调用了
你就可以不必理会那个泄露警告，那个不是100%的准确

[AndonVC]

改不出来,哭啊...
怎么办啊

[居易锦风]

BOOL CBaseDbProxy::Close()
{
if ( m_bConnected )
{
if ( m_pDbCon != NULL )
{
if ( m_pDbCon->IsConnected() )
{
BOOL bResult = m_pDbCon->Disconnect();
m_pDbCon->Release();
delete m_pDbCom;
m_pDbCon = NULL;
return bResult;
}
}
}
return FALSE
...
加上delete m_pDbCom;
