  2. Add the following line just before the end of the OnSize function definition block (before it returns):

    // update the container offset.   
    L_ContainerSetOffset ( pContainer, - prcView->left, - prcView->top, 0 ) ; 

  3. Add the following argument to the OnHScroll function definition, after "L_UINT code,":

    pCONTAINERHANDLE pContainer, 

  4. Add the following line before the UpdateWindow function in the OnHScroll function definition:

    // update the container offset.   
    L_ContainerSetOffset ( pContainer, - prcView->left, - prcView->top, 0 ) ; 

  5. Add the following argument to the OnVScroll function definition, after "L_UINT code,":

    pCONTAINERHANDLE pContainer, 

  6. Add the following line before the UpdateWindow function in the OnVScroll function definition:

    L_ContainerSetOffset ( pContainer, - prcView->left, - prcView->top, 0 ) ; 

  7. Add the following argument to the OnSize function call, in the WndProc function, after the argument "hWnd," :

    pContainer,
