Is this programe have some problem,help me

#include <windows.h>
#include <cstdio>
#include <process.h>

#define MY_MSG WM_USER+100
const int MAX_INFO_SIZE = 20;

HANDLE hStartEvent; // thread start event
                    /*
                    要把SETTING 改为多线程的
                    Project->Settings->C/C++,
                    在Category 中选Code Generation, 然后在Use run-time libray 中选一个
                    Multithread 配置
