    Thumbs up Urgent help visualstudio build errors

    I face errors while compiling code in vs2008 shown below. it gives unexpected errors..what could be the reason?

    Code:
    #define _WIN32_WINNT 0x0602
    #include <Windows.h>
    #include <powrprof.h>
    #include <stdio.h>
    #include <tchar.h>
    
    
    #pragma comment(lib, "PowrProf.lib")
    
    static ULONG isConnectedStandby(PVOID Context, ULONG Type, PVOID Setting);
    
    ULONG isConnectedStandby(PVOID Context, ULONG Type, PVOID Setting)
    {
    switch(Type)
    {
    case PBT_APMSUSPEND:
    printf( "PBT_APMSUSPEND");
    break;
    case PBT_APMRESUMESUSPEND:
    printf( "PBT_APMRESUMESUSPEND");
    break;
    case PBT_APMRESUMEAUTOMATIC:
    printf( "PBT_APMRESUMEAUTOMATIC");
    break;
    default:
    printf( "DEFAULT");
    break;
    }
    return 0;
    }
    
    
    static _DEVICE_NOTIFY_SUBSCRIBE_PARAMETERS testCallback = {
    isConnectedStandby,
    nullptr
    };
    
    
    int __cdecl main()
    {
    
    
    HPOWERNOTIFY RegistrationHandle;
    
    printf("Hello world\n");
    
    PowerRegisterSuspendResumeNotification(
    DEVICE_NOTIFY_CALLBACK,
    &testCallback,
    &RegistrationHandle
    ); 
    /*
    while(true) {
    Sleep(1000);
    }
    */
    return 0;
    }

    Did you bother to read the manual before using that structure?
    DEVICE_NOTIFY_SUBSCRIBE_PARAMETERS structure (Windows)

    Minimum supported client Windows 8 [desktop apps only]
    > #define _WIN32_WINNT 0x0602
    ...

    You need the LATEST SDK (one which supports Windows 8), and you also need Windows 8 as your platform.

    Just pasting a single #define line into the start of your code doesn't magically transform the rest of your system into Windows 8.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Somewhere on microsoft,com I guess.
    Use google for clues.
