title: how to drag a text string and its hyperlink from an HTML page to a TEdit
body: <p>I hope to to drag a text string and its hyperlink from an HTML page  to a TEdit.
  For example </p>
  
  <p>displays <code>aaa</code></p>
  
  <p>actual string is <code>&lt;a href=somewhere.html&gt;aaa&lt;/a&gt;</code></p>
  
  <p>I try to use drag&amp;drop vcl, but found that it only can catch <code>aaa</code> itself rather than the string and its hyperlink.</p>
  
  <p>Welcome any comment</p>
  
  <p>Thanks
