Question

I am trying to make a C# Windows form in Visual Studio so I can draw on the form (like a basic version of Microsoft Paint). I am working through an example in a C# 2012 boo

Answer 1

Try the paint events for drawing. this will help you. The link is just an example. you need to implement as per the requirements

Answer 2

 private void Form1_Paint(object sender, EventArgs e)
    {
        if (shouldPaint)
        {
            using (Graphics graphics = CreateGraphics())
            {
                graphics.FillEllipse(new SolidBrush(Color.BlueViolet), e.X, e.Y, 4, 4);
            }
        }
    }

Alex Fr provided an excellent set of drawing tools in his DrawTools article and these tools serve as a basis for Draw Tool Redux.

Here's a tool I recently wrote by adding to Draw Tool Redux, it creates Epilogs for Mathematica:
