How to get image RGB/16????????

My problem is:%26lt;br /%26gt;1. When you start my project with Hidden. I customize it to:%26lt;br /%26gt; - get first memory address of image RGB/8 and store data of image in file ''abc.txt'':%26lt;br /%26gt;%26lt;br /%26gt;/////Code is customized/////////////////////////////////////////////////%26lt;br /%26gt;%26lt;br /%26gt;/////Declare global parameter///////%26lt;br /%26gt;#include ''PITerminology.h''%26lt;br /%26gt;#include %26lt;vector%26gt;%26lt;br /%26gt;#include %26lt;time.h%26gt;%26lt;br /%26gt;%26lt;br /%26gt;using namespace std;%26lt;br /%26gt;%26lt;br /%26gt;#define HERROR(FUNC) if (true) { error = FUNC;
