Dragable Transparent Windows Form in C# - Part 2

 Hi In my previous blog i shown to create a transparent windows form.In this post i am going to show how to drag the transparent windows form to any location.

Create a event handler for Picturebox(mouseup,mousedown and mousemove) and paste the following piece of code.

private void pictureBox1_MouseDown_1(object sender, MouseEventArgs e)

        {

            if (e.Button == MouseButtons.Left)

            {

                drag = true;

                x = Cursor.Position.X - this.Left;

                y = Cursor.Position.Y - this.Top;

            }

        }

        private void pictureBox1_MouseUp(object sender, MouseEventArgs e)

        {

            drag = false;

        }

        private void pictureBox1_MouseMove(object sender, MouseEventArgs e)

        {

            if (drag)

            {

                this.Top = System.Windows.Forms.Cursor.Position.Y - y;

                this.Left = System.Windows.Forms.Cursor.Position.X - x;

            }

            this.Cursor = Cursors.Default;

        }
