Hello,

Probably you are trying to open just step01.cpp and compile it.

It is better to load the tutorial .ide file and use it, as it has
all the needed settings.


This .cpp is intended for a Windows 32-bit GUI program.
But if you load it without a project, the default settings
will be used, and they are for 32-bit Console program.
You can chagne this by right-clicking on the .cpp file
and selecting Target Expert.
