C # method of drawing without blinking

After reading some articles, select a one with better test results to record the results for future search. Personal summary.

1. In the constructor, execute

This. setstyle (controlstyles. optimizeddoublebuffer | controlstyles. allpaintinginwmpaint, true );

2. In the paint Event Response Function, execute

Bufferedgraphicscontext currentcontext = bufferedgraphicsmanager. Current;
Bufferedgraphics mybuffer = currentcontext. Allocate (E. Graphics, E. cliprectangle );
Graphics G = mybuffer. graphics;
G. smoothingmode = smoothingmode. highquality;
G. pixeloffsetmode = pixeloffsetmode. highspeed;
G. Clear (this. backcolor );
// Draw with G
Mybuffer. Render (E. Graphics );
G. Dispose ();
Mybuffer. Dispose (); // release resources

This test is very effective and has no flashes.
