I have a COM DLL implementing the IEmptyVolumeCache interface.  One of the 
functions is :

  virtual HRESULT STDMETHODCALLTYPE ShowProperties(
      HWND hwnd);

This function is used to show a form that displays all files about to be 
purged.

I cannot work out how to make use of the hwnd parameter correctly.

For example, if a user minimizes my form (which is currently modal) I'm not 
sure how to make the calling (microsoft) window also minimize.  And, if a 
user restores either form to make sure they both restore.

Are there any other reasons for using the passed handle ?

Any tips ?
