My functions...

For the first part of our team assignment I did this three functions...


 1.

void CDialog::draw(int fn = C_FULL_FRAME){
    if(fn == C_FULL_FRAME){                //If fn is C_FULL_FRAME
        CFrame::draw();                    //it will call its parent draw. Then It will draw all the Fields in the Dialog.
    }                                      // it will call its parent draw. Then It will draw all the Fields in the Dialog.
    if(fn != C_FULL_FRAME){                // If fn is not C_FULL_FRAME
        for (int i = 0; i < _fnum; i++){
        _fld[i]->draw;                     // then it will just draw all the Fields in the Dialog.
        }
    }
    if(fn > 0){                            // If fn is a non-zero positive value
        _fld[(fn-1)%_fnum]->draw();   // then it will only draw Field number fn in the dialog.
    }
}

2.


  CLabel::CLabel(const CLabel& L):CField(L){
      if(this!=&L){
            width(L.width());
            if(L._data){
                _data = new char[strlen((char*)L._data+1)];
                strcpy(_data,L._data);
            }
            else{
                _data = (char*)0;
            }
        }
  }

3.


void CLabel::set(const void* str){
      if(width() > 0){        //if width() is greater than zero
        strncpy((char*)_data, (char*)str, width());
        ((char*)_data)[width()] = 0;
      }
      if(width() == 0){
        delete [] _data;
        _data = new char[len+1];
        strcpy((char*)_data, (char*)str);
      }
 }


==========


Probably they have several few mistakes which were changed in final team project.
