At present, the default translation of Form_Load is as a method that is invoked from the form constructor.  You may want to migrate it to an event handler instead.  The following RefactorLibrary for the VB7Lang meta-language definition will help you do that:

mig.VB7Lang.xml
---------------
<MetaLanguage>
<!--
Description: apply metalang overrides
-->
<Refactor id="Basic" >
<Replace id="Patterns">
   <pattern id="FOR">
      <subcode id="Load">
         <!-- hook Form_Load to Load Event rather than deleting it -->
         <!-- see also postedit to remove calls to Form_Load in ctor -->
         <all role="event" narg="0" code="Load" />
      </subcode>
   </pattern>
</Replace>
</Refactor>
</MetaLanguage>
