CTTable hTable(hSession);

CTRecord hRecord(hTable);

NINT datno, count = 0;

// logon to c-tree

hSession.Logon(SERVER, USER, PASSWD);

// open the file using c-tree ISAM

datno = (NINT)OPNRFILX((COUNT) -1, "test309.dat", (COUNT)0, NULL);

// attach to table

hTable.Attach(datno);

// read the records

if (hRecord.First())

{

count++;

}

while (hRecord.Next());

// cleanup

hTable.Detach();

hSession.Logout();
