Question

How do I draw a circle and line in the picturebox?

Answer 1

the picturebox is a control and has an image as source - so you have to draw on the image and hand the image to the control to show it

MyImage = new Bitmap(fileToDisplay);
pictureBox1.ClientSize = new Size(xSize, ySize);
pictureBox1.Image = MyImage;
