Flicker

[Umair Ahmad khan]

how can i remove flicker from my program .. i am trying to make a simple game of tettris (don't know how to spell it correctly). i have to move a shape from top to bottom so my control is doing this for me .. logic i m using is simple ( i think it is) i m using paint function of my control just to fill a perticular block whose value is 1 and and empty whose value is 0 so i need to call paint function after every some time. but Invalidate function is creating flicker. is there any other way i can use or i i can paint some shapes constantly without using paint function ?? i have tried to use some other my own written function but they are not working until i call 'em from paint function of my control what should i do..

Look up "Double Buffering".

Ian Darling The world is a thing of utter inordinate complexity ... that such complexity can arise ... out of such simplicity ... is the most fabulous extraordinary idea ... once you get some kind of inkling of how that might have happened - it's just wonderful ... the opportunity to spend 70 or 80 years of your life in such a universe is time well spent as far as I am concerned - Douglas Adams

Search Codeproject or the web for System.Windows.Forms.ControlStyles.DoubleBuffer, it will get rid of the 'flashing'/flicker when you draw to a windows form.

Add these 3 lines to your form constructor // Enable Double Buffering to remove flicker this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.DoubleBuffer, true); Hope this helps Publicjoe C# Tutorial at http://www.publicjoe.f9.co.uk/csharp/tut.html C# Ebook at http://www.publicjoe.f9.co.uk/csharp/samples/ebook.html VB Tutorial at http://www.publicjoe.f9.co.uk/vbnet/vbnet.html VB Ebook at http://www.publicjoe.f9.co.uk/vbnet/samples/ebook.html Mirrors at http://dowhileloop.com/publicjoe/ and http://publicjoe.dowhileloop.com

Or better yet, a single line, with the flags OR'd together: this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer, true);
