Rx VerInfo

Description:
This manipulates the information from the Microsoft Version Resource (VERSIONINFO) structure. Whenever the FileName property is changed, the class properties are updated.

Declaration: constructor Create(const AFileName: string);

The Create method allocates memory to create a TVersionInfo object, passes it the file name of the interesting file and read version information about a specified file from VERSIONINFO resource. If the reading succeeds, the Valid property is True. If the reading fails, the Valid property is False.
