title: Easiest way to open chm files programmatically?
body: <p>I have a legacy 32-bit application written in Borland's C++ Builder. I need to show specific pages from within a HtmlHelp file programmatically. Until now I've been doing this via HtmlHelp.ocx, but this does not work on x64 versions of Windows Vista / Windows7 as described in <a href="https://stackoverflow.com/questions/1748592/loadlibrary-on-ocx-file-fails-in-windows-7-x64">this thread</a>.</p>
  
  <p>I can't compile the application as 64-bit executable. Therefore the only workaround I have found so far is to create a 32-bit component implementing a COM object which loads and calls into the 32-bit DLL, and exposes the 32-bit DLL interface as a COM interface. </p>
  
  <p>That sounds far too complicated just to display a chml file with a specific topic. There must be something else. But what is it? </p>
