How to display a textBox in topleft,topright,center and random positions of the screen in c#?

How to change the opacity of the windows form using c# code?

For topleft, topright and center use:

public void MoveToTopLeftCorner() {     txtBox.Left = 0;     txtBox.Top = 0; } public void MoveToCenter() {     txtBox.Left = (txtBox.Parent.Width / 2) - (txtBox.Witdh);     txtBox.Top = (txtBox.Parent.Height/ 2) - (txtBox.Height); }

For random, place a Timer on you Form and in the Tick event of the timer place code that look like this:

private void timer1_Tick(object sender, System.EventArgs e) {     Random rnd = new Random();     txtBox.Left = rnd.Next(0, Width - txtBox.Width);     txtBox.Top = rnd.Next(0, Height - txtBox.Height); }

For settings the opacity use the Opacity property of the Form class:

this.Opacity = 0.5;

For topleft, topright and center use:

public void MoveToTopLeftCorner() {     txtBox.Left = 0;     txtBox.Top = 0; } public void MoveToCenter() {     txtBox.Left = (txtBox.Parent.Width / 2) - (txtBox.Witdh);     txtBox.Top = (txtBox.Parent.Height/ 2) - (txtBox.Height); }

For random, place a Timer on you Form and in the Tick event of the timer place code that look like this:

private void timer1_Tick(object sender, System.EventArgs e) {     Random rnd = new Random();     txtBox.Left = rnd.Next(0, Width - txtBox.Width);     txtBox.Top = rnd.Next(0, Height - txtBox.Height); }

For settings the opacity use the Opacity property of the Form class:

this.Opacity = 0.5;
