Question

I need to resize a Rectangle at runtime. I draw the Retangle on the Form1_Paint() but unable to resize itt.. Graphics graph = this.CreateGraphics(); Pen penCurrent = new Pen(Color.Red); Rect = new Rectangle(300 50 150 75); graph.DrawRectangle(penCurrent Rect); need some help!

First of all you don't want to call CreateGraphics you should do everything in the Paint event handler. To resize a rectangle just change the boundaries of the rectangle outside the Paint event. for example: OnPaint() { e.Graphics.DrawRectangle(30 30 x y); } Set x and y outside of the event handler and call invalidate on the form region OnButtonPressed (object sender EventArg e) { x = x+5; y = y + 5; Invalidate(29 29 x+1 y+1); // force it to redraw }
