so i'm messing around, getting hang of things , i'm making picture box move, have done. show me how make movement more fluent not slow down much?

code:

using system; using system.collections.generic; using system.componentmodel; using system.data; using system.drawing; using system.linq; using system.text; using system.windows.forms;  namespace meh {     public partial class form1 : form     {         picturebox test = new picturebox();         public form1()         {             initializecomponent();             formborderstyle = formborderstyle.none;             windowstate = formwindowstate.maximized;              test.image = properties.resources.platinumgrass;             test.location = new point(0, 0);             test.width = 32;             test.height = 32;             this.controls.add(test);             keydown += new keyeventhandler(form1_keydown);           }          private void form1_keydown(object sender, keyeventargs e)         {             int x = test.location.x;             int y = test.location.y;             int xmax = screen.primaryscreen.bounds.width - 32;             int ymax = screen.primaryscreen.bounds.height - 32;             if (e.keycode == keys.right && x < xmax ) x += 20;             if (e.keycode == keys.left && x > 0) x -= 20;             if (e.keycode == keys.up && y > 0) y -= 20;             if (e.keycode == keys.down && y < ymax) y += 20;              test.location = new point(x, y);         }          private void form1_load(object sender, eventargs e)         {          }     } } 

i suggest not using winforms game development

but can add these lines form constructor make improvements.

setstyle(controlstyles.resizeredraw, true); setstyle(controlstyles.userpaint, true); setstyle(controlstyles.allpaintinginwmpaint, true); setstyle(controlstyles.optimizeddoublebuffer, true);    

also can add loop movement part improve little bit

private void form1_keydown(object sender, keyeventargs e) {     int xmax = screen.primaryscreen.bounds.width - 32;     int ymax = screen.primaryscreen.bounds.height - 32;      (int = 0; < 10; i++)     {         int x = test.location.x;         int y = test.location.y;         if (e.keycode == keys.right && x < xmax) x += 2;         if (e.keycode == keys.left && x > 0) x -= 2;         if (e.keycode == keys.up && y > 0) y -= 2;         if (e.keycode == keys.down && y < ymax) y += 2;         test.location = new point(x, y);         application.doevents();     } }
