using graphics in windows forms

Question

I am new to GDI+ and the graphics class. I read the tutorial on the C# corner site. In it, you declear the graphics class instance as: Graphics g = e.Graphics; (e being the EventArgs variable passed into the paint function) if i want to draw something when the form is resized, i like the resize event to "resize_draw" but the eventsarg no longer contains Graphics. How would i use the graphics class in this function? or is it not possible? Hope that made sence.

I'm assuming you're doing the drawing by overriding the OnPaint method. You could override the OnPaint method and design the drawing routines to draw based on the form's size then override the OnResize method to look like this: protected override void OnResize(EventArgs e) { base.OnResize(e); this.Invalidate(); } That should force the form to call your OnPaint method every time you resize the form.
