/////////////////////////////////////////////////////////////////////////////
// Name: samples/dll/my_exe.cpp
// Purpose: Sample showing how to use wx DLL from a Win32 application

/*
This program is intentionally as simple as possible and shouldn't be seen
as an example of how to write a proper Win32 application (why should you
want to do this anyhow when you have wxWidgets). It's just a test bed for
the wx DLL which it uses.
