new Double Buffering

[HexaDeveloper]

hi all i made double buffering in a form with this.DoubleBuffering = true; but this is not working in the tab so i wanna to know how to make double buffering by using Bitmap to enhance performance by drawing in memory as bitmap and then draw my background in the bitmap and draw bitmap again to the screen can any one tell me how to begin search how to use this technique thanx Generator

I think SetStyles is the method you call, turn on double buffering and all drawing in WMPAINT.

hi, i tried this but the tabPage doesnot contain method setStyle iam making a method now to use BufferedGraphics, BufferedContext,BufferedManager to draw to buffer then draw to TabPage but iam still trying this and also if there is any method easier thanx Generator

public void tab_Paint(object sender, PaintEventArgs e) { TabPage tab = (TabPage)sender; BufferedGraphicsContext context; BufferedGraphics buffer; // context = BufferedGraphicsManager.Current; /// Dedicated context /// used when highly animated graphics context = new BufferedGraphicsContext(); Graphics grfx = tab.CreateGraphics(); buffer = context.Allocate(grfx, tab.ClientRectangle); drawSurfaceToBuffer(buffer.Graphics); buffer.Render(grfx); buffer.Dispose(); grfx.Dispose(); } public void drawSurfaceToBuffer(Graphics bufferGrfx) { /// some processing that used the buffer grfxs } this code i understand it from MSDN and write it to reduce Graphics Flicker but it does not make any thing at all also it make my background of tabpage black and the original is white is there any suggestions please Generator
