奇怪的问题？
C:\WINDOWS\Desktop\GAClient\GACSocket.cpp(102) : error C2664: 'CopyMsg' : cannot convert parameter 1 from 'class CMsg' to 'class CMsg'
void CGACSocket::ProcessPendingRead()
{
do
{
ReceiveMsg();
CMsg* pmsg=new CMsg;
pmsg->CopyMsg(msg);//出错
AfxBeginThread(DealData,pmsg);
//Deal();
}
while(!m_pArchiveIn->IsBufferEmpty());
}
void CMsg::CopyMsg(CMsg msg)
{
flag=msg.flag;
Floor=msg.Floor;
indi.IndividualInit(Floor);
for(int i=0;i<Floor*(LENGTH1+LENGTH2)+1;i++)
indi.chrom[i]=msg.indi.chrom[i];
indi.fitness=msg.indi.fitness;
for(i=0;i<Floor;i++)
indi.Kind[i]=msg.indi.Kind[i];
for(i=0;i<Floor;i++)
indi.Thick[i]=msg.indi.Thick[i];
for(i=0;i<FREQNUM;i++)
indi.value[i]=msg.indi.value[i];
m_bOnline=msg.m_bOnline;
for(i=0;i<255;i++)
m_strAction[i]=msg.m_strAction[i];
}
怎么解决？

void CMsg::CopyMsg(CMsg msg)
定义成void CMsg::CopyMsg(CMsg* pMsg)
或者void CMsg::CopyMsg(CMsg& msg)
传引用或者指针，
你这样的定义可能问题出现在CMsg类的构造函数.
"no copy constructor"?Top
