使用FormatMessage函数编写一个内核错误码查看器

void CNTLookErrorDlg::OnBnClickedBtnLookup()
{
    // TODO: 查找错NTSTATUS值对应的错误
    LPVOID lpMessageBuffer;
    HMODULE Hand = LoadLibrary(_T("NTDLL.DLL"));
    DWORD dwErrCode = 0;

    dwErrCode = GetDlgItemInt(IDC_EDIT_ERRCODE);
    FormatMessage( 
        FORMAT_MESSAGE_ALLOCATE_BUFFER | 
        FORMAT_MESSAGE_FROM_SYSTEM | 
        FORMAT_MESSAGE_FROM_HMODULE,
        Hand, 
        dwErrCode,  
        MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
        (LPTSTR) &lpMessageBuffer,  
        0,  
        NULL );

    // Now display the string.
    GetDlgItem(IDC_EDIT_ERRMSG)->SetWindowText((LPTSTR)lpMessageBuffer);
    // Free the buffer allocated by the system.
    LocalFree( lpMessageBuffer ); 
    FreeLibrary(Hand);
}
