// **ADDED**  Everything in this Header is added functionality.

// Import the Type Library to make COM stuff a bit easier to read.
// I put it here, since ReadStatus is the only class using its data.
// This import can be used instead of the MFC generated COM Wrapper (ComACRsrvr.h). 
// We will leave the MFC generated COM wrapper code in the main application to show
// the use of both.  When using both, let the #import use a namespace (default) or 
// else there will be name conflicts.
