title: Passing parameters in the Form constructor, winforms c#
body: <p>I have a following inheritance hierarchy:</p>
  
  <p>Class A : Form <br/>
  Class B : Class A<br/></p>
  
  <p>Class A needs to be able to accept a parameter so that I can create the instance of Class B like this:</p>
  
  <pre><code>ClassB mynewFrm = new ClassB(param);
  </code></pre>
  
  <p>How do I define such a constructor in Class A?</p>
  
  <p>thanks!</p>
  
  <p>I am using Winforms in .net 3.5, c#</p>
  
  <p>EDITED:
  Class A and Class B are defined as forms, using partial classes. 
  So I guess this is turning into a question about partial classes and custom (overriden) constructors.</p>
