The answer to your question is no. You cannot create a messagebox with a checkbox. You would have to create a custom dialog box. You need to create a form that looks the way you wish it to look and use the ShowDialog() method to display the form. This will display a modal dialog box in your application. The code after the ShowDialog method is not executed until the dialog box is closed.

using (Form2 frm = new Form2())
            {
                frm.ShowDialog();
                if (frm.DialogResult == DialogResult.Yes)
                {

                }
                else if (frm.DialogResult == DialogResult.No)
                {

                }
            }

On clicking yes or no from within the dialog box, you would do the following to close the dialog box with a DialogResult

  private void btnYes_Click(object sender, EventArgs e)
        {
            DialogResult = DialogResult.Yes;
        }

  private void btnNo_Click(object sender, EventArgs e)
        {
            DialogResult = DialogResult.No;
        }
