CList::Find()

Hi,

I have a:

typedef struct _CLIENTSOCKETS
{
    CString o_Date;
    CTime o_LoginTime;
    CString o_Time;
    CString o_TimeOnline;
    CString o_PeerName;
    long n_BytesIn;
    long n_BytesOut;
    CString o_BytesIn;
    CString o_BytesOut;
    UINT n_Port;
    CSvrSocketComm* po_SvrSocketComm;
    struct _CLIENTSOCKETS* p_Next;
    struct _CLIENTSOCKETS* p_Prev;
} *PCLIENTSOCKETS, CLIENTSOCKETS;

and a :

    CList<CLIENTSOCKETS,CLIENTSOCKETS&> o_ClientSockets;

I want to Find a certain CLIENTSOCKETS element in the CList.

CLIENTSOCKETS a;
pt_Position = o_ClientSockets.Find(a);

I get an error :

error C2678: binary '==' : no operator defined which takes a left-hand
operand of type 'const struct _CLIENTSOCKETS' (or there is no
acceptable conversion)
        c:\program files\microsoft visual studio\vc98\mfc\include
\afxtempl.h(1036) : see reference to function template instantiation
'int __stdcall CompareElements(const struct _CLIENTSOCKETS *,const
struct _CLIENTSOCKETS *)' being compiled
Error executing cl.exe.

What i want is to store structures in the CList and then removing one
of them using a search key for which to remove.

What am i doing wrong ?
