Question

I have a problem with my winforms C# project.

I want to move a new (custom) button around the form (at run time).
How can I do that?

    Button[] buttons = new Button[1000];
        int counter = 0;
        Button myText = new Button();
private void button2_Click(object sender, EventArgs e)
        {
                Button myText = new Button();
                myText.Tag = counter;
                myText.Location = new Point(x2,y2);
                myText.Text = Convert.ToString(textBox3.Text);
                this.Controls.Add(myText);
                myText.MouseMove += new MouseEventHandler(myText_MouseMove);
                myText.MouseDown += new MouseEventHandler(myText_MouseDown);
                buttons[counter] = myText;
                counter++;
        }
 public void myText_MouseMove(object sender, MouseEventArgs e)
        {
            int s = e.GetHashCode();
            int check = 0;
            for (int i = 0; i < counter; i++)
            {
                if (buttons[i].GetHashCode() == s)
                    check = i;
            }
            if (e.Button == MouseButtons.Left)
            {
                buttons[check].Left += e.X - move.X;
                buttons[check].Top += e.Y - move.Y;
            }
        }
        void myText_MouseDown(object sender, MouseEventArgs e)
        {
            move = e.Location;
        }

I use the code above to create the new button and I am trying to move it around the form.

If I code for just 1 button I am able to move it but, I want to be able to do this for more buttons as well.

Try this

public void myText_MouseMove(object sender, MouseEventArgs e)
    {
        Button button = (Button)sender;
        if (e.Button == MouseButtons.Left)
        {
            button .Left += e.X - move.X;
            button .Top += e.Y - move.Y;
        }
    }
