LImageViewer::BeginUpdate
#include "ltwrappr.h"
L_INT LImageViewer::BeginUpdate(uFlags)
|
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 LImageViewer::EndUpdate function.
|
Parameter |
Description |
|
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 LImageViewer::EndUpdate. 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.

Example
This example creates a medical viewer control and two cells. then it will ask whether the apply some effects on the cell with or without using BeginUpdate/EndUpdate. Run this sample twice and see the difference
