title: Enable button function inside backgroundWorker
body: <p>I am using windows form application to create gui. I have create a form with several button. The functionality of the first button called button1 is to read a video from hard disk and display it to a picturebox. The last line of button1 code is to enable another button:</p>
  
  <pre><code> button2-&gt;Enabled = true;
  </code></pre>
  
  <p>Button1 code is inside a backgroundworker. The result of this, it works fine, however it doesnt enable the button2. Is there issue using button properties inside backgroundworker?</p>
