: the structure :

: CONNECTLINE *clptr;
: LINEPtr *next;
: };

: //(it is in a member function of class)
: LINEPtr *clp,FirstPtr;
: FirstPtr=clp;

Without looking to much further, You are assignement does not look right
unless, you meant

LINEPtr *clp, *FirstPtr;
             ^^^

: //when i use
: clp->next=new LINEPtr;
: clp=clp->next;
: clp->clptr=(something)
: clp->next=FirstPtr->next;
: //then i delete
: clp=clp->next;
: delete clp;
: //the value of clp->next become 0x3
: //and I can't use it to delete the next one...

: //but this kind pointer&structure
: //i can use it exactly in other place
: //why?
