I've been trying to draw a line between two objects for a long time now, but it still won't work.
My program is supposed to make two picture boxes (Already made, called PB1 and PB2) and connect them with a line on the form.
I have this:
public void DrawStuff(object sender, PaintEventArgs e)
{
Pen blackPen = new Pen(Color.Black, 3);
Point point1 = new Point(PB[0].Location.X, PB[0].Location.Y);
Point point2 = new Point(PB[1].Location.X, PB[1].Location.Y);
e.Graphics.DrawLine(blackPen, point1, point2);
CreateGraphics();
}
But I can't call the function! Also, the Boxes are being created with a button, so it can't draw from the start, it has to do it after I push that button. If anyone has a working code, please let me know, I'm about to break down.
CreateGraphics() explicitly. This is a crime against humanity, except for very rare situations.Paint event (or override OnPaint()) of your Form. Write your line drawing code in there.Something like this:
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
using(var blackPen = new Pen(Color.Black, 3))
e.Graphics.DrawLine(blackPen, PB[0].Location, PB[1].Location);
}
this.Invalidate().Collected from the Internet
