how can i solve this error in my win32 reading image file code

I couldnt solve this problem. I dont know why im getting this error message.

Exception thrown at 0x7642DEB5 (KernelBase.dll) in Project2.exe: 0xC0000005: Access violation writing location 0x00000000.

Error at ReadFile(file,lpBuffer, nNumberOfBytesToRead-1, NULL, NULL)

Here my code. I am trying to access a JPG file to read its header.

#include<Windows.h>
#include<iostream>

int main()
{
    LPCTSTR path = "jpg.jpg";
    DWORD nNumberOfBytesToRead;

    HANDLE file = CreateFile(path, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

    if (file == INVALID_HANDLE_VALUE)
    {
        std::cout << "The file couldnt be opened" << std::endl;
    }

    nNumberOfBytesToRead = GetFileSize(file, NULL);

    BYTE *lpBuffer = new BYTE[nNumberOfBytesToRead-1] ;

    if (ReadFile(file,lpBuffer, nNumberOfBytesToRead-1, NULL, NULL))
    {
        delete[] lpBuffer;
        CloseHandle(file);
        std::cout << "The file couldnt be read" << std::endl;
    }
    CloseHandle(file);
    delete[] lpBuffer;

    if (file != 0)
    {
        std::cout << "The file has been closed" << std::endl;
    }

    system("PAUSE");
    return 0;
}

Thank you i have solved this problem. I have an another problem

Here my new code.

#include<Windows.h>
#include<iostream>

int main()
{
LPCTSTR path = "jpg.jpg";
DWORD nNumberOfBytesToRead = 0;
DWORD nNumberOfBytesRead = 0;
HANDLE file = CreateFile(path, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

if (file == INVALID_HANDLE_VALUE)
{
    std::cout << "The file couldnt be opened" << std::endl;
}

nNumberOfBytesToRead = GetFileSize(file, NULL);

BYTE *lpBuffer = new BYTE[nNumberOfBytesToRead];

if (ReadFile(file, lpBuffer, nNumberOfBytesToRead, &nNumberOfBytesRead, NULL))
{
    std::cout << "The file couldnt be read" << std::endl;
}

CancelIo(file);
CloseHandle(file);
delete[] lpBuffer;

system("PAUSE");
return 0;
}
