Implementing Scrollbars: Step 1

Modify the window style specified in the InitInstance function so that the window can have scrollbars. You do this by adding the WS_VSCROLL and WS_HSCROLL styles, as shown in the following code: 

   /* Create a main window for this application instance. */ 
   hWnd = CreateWindow ( 
                        TEXT("LEADWClass"), 
                        TEXT("LEADTOOLS Sample Application"),  /* Window title */ 
                        WS_OVERLAPPEDWINDOW|WS_VSCROLL|WS_HSCROLL, /* Window style */ 
                        CW_USEDEFAULT, /* Default horizontal position */ 
                        CW_USEDEFAULT, /* Default vertical position */ 
                        rWndSize.right - rWndSize.left,  /* Window width */ 
                        rWndSize.bottom - rWndSize.top,  /* Window height */ 
                        NULL,   /* Overlapped windows have no parent */ 
                        NULL,   /* Use the window class menu */ 
                        hInstance,  /* This instance owns this window */ 
                        NULL    /* Pointer not needed */
