L_DispContainerBeginUpdate

#include "l_bitmap.h"
L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerBeginUpdate(hCellWnd, uFlags)
HWND hCellWnd;	/* handle to the cell window */
L_UINT uFlags;	/* reserved for future use */
Stops the viewer from being refreshed if any change is applied, it's generally useful to increase the control speed efficiency. To resume refreshing, use the L_DispContainerEndUpdate function.
Parameter	Description
hCellWnd	A handle to the window that represents the Medical Viewer Cell.
uFlags	Reserved for future use. Pass 0.
Returns
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
Comments
Stops the viewer from refreshing after each change is applied, until refreshing is resumed by calling L_DispContainerEndUpdate. At that point the viewer will repaint to show all of the changes that have been made. This is useful for better visual results and for speed efficiency.
