Version Info Extractor

 
   

Objectives

It was required to design and implement the set of C++ classes getting Version Info data from the Windows executable files.
 

Results

The required functionality was implemented using MS Visual Studio 6.0. Rather than use the standard Win API to work with the Version Info, special classes had to be designed because of the following reasons: Win API allows to get the property by its name, but the properties with unknown names stay inaccessible. Also, Win API fails to get the Version Info from some files (as a rule, from those storing the Version Info in ANSI format), though this data can be viewed with the help of Windows Explorer. These were the shortcomings to eliminate.
   

Technical peculiarities

To access the Version Info data, two parsers were implemented providing complete access to the ANSI or UNICODE-formatted Version Info stored in a binary dump. The parsers were designed on the basis of the format description taken from
  MSDN (which may not be called exhaustive), as well as the investigation of Version Info binary dumps of different files (first of all, this concerns those files that caused the problems when the Win API approach was used).
