Properties.legacy.cpp

The Properties.legacy program is a legacy version of the Properties.cpp example.

Note

This is a legacy version of Properties.cpp only needed when working on a system with a non C++11 capable compiler (e.g. Visual Studio smaller than version 2013 or gcc smaller than version 4.8. However please note that Impact Acquire these days is built using gcc 5.5.0 thus using an older compiler for building applications will most likely not result in working binaries!). For a detailed description please have a look on the modern version of this example. Even though the used C++ code is slightly different the general idea of the example is the same!
