HInstance: handle instance (the process generated by the running program. The handle is an instance of the running program and uniquely identifies it)

(Win32 or 64: The instance handle is the module handle)

PreInstance: determines whether other program instances are in progress and port the previous instance to your data zone.

SzCmdLine: Command Line for loading files to memory when the program is running

NCmdShow: the initial display method of the program

MassageBox: dialog box function (NULL: parent window handle, subject string, title bar string, OK button)
