Start with the project you created in Setting Container Metrics.

1. Add the following argument to the OnSize function definition, after "HWND hWnd,":

   pCONTAINERHANDLE pContainer, 

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:

   // update the container offset.   
   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, 

8. Add the following argument to the OnHScroll function call, in the WndProc function, after the argument "LOWORD ( wParam ),":

   pContainer, 

9. Add the following argument to the OnVScroll function call, in the WndProc function, after the argument "LOWORD ( wParam ),":

   pContainer, 

10. Compile and run the project by selecting Build->Rebuild Solution from the menu, and then Debug->Start Without Debugging.
