title: C# Repeated Image in PictureBox
body: <p>I am working on a C# piano and have encountered a problem.</p>
  
  <p>I have built the keyboard and the staff, and each key pressed by the user is displayed in its respective position on the staff.</p>
  
  <p>My problem is that the image is repeated beyond the first key (be it any key). For instance, if I press a key the second time, two images are displayed on the staff for that particular key press. If I press a fifth key (be it any key), five images are displayed on the staff.</p>
  
  <p>How do I solve this problem please? I only want to display one image per key. Thanks.</p>
  
  <p><strong>Edit</strong></p>
  
  <p>I have solved the problem.  Thanks :)</p>
