c (windows)- 將char、wchar、tchar轉換為unsigned long、unsigned long long

參考：MSDN - strtoul, _strtoul_l, wcstoul, _wcstoul_l  、  strtoull-replacement 、C语言的三种整型数据类型：int、short int和long int
需求：

1. 將char、wchar、tchar轉換為unsigned long (下面以TCHAR為範例)：
   

     unsigned long len = 0;
     TCHAR queryBuf[32]  = _T("6588775699");
     len = _tcstoul(queryBuf,NULL,0);
   

   
   其餘對應為：strtoul, _strtoul_l, wcstoul, _wcstoul_l
2. 將char、wchar、tchar轉換為unsigned long longg (下面以TCHAR為範例)：
   

     unsigned long long len = 0;
     TCHAR queryBuf[32]  = _T("6588775699");
     len = _tcstoui64(queryBuf,NULL,0);
   

   
   其餘對應為：_strtoui64(), _wcstoui64() and _tcstoui64()
3. 而使用printf、sprintf的unsigned long long的對應format為%llu：
   

                   
      unsigned long long ll =  6588775699;
      TCHAR tszHeader[MAX_FILENAME_LEN] = {0};
      _stprintf(tszHeader,_T("Range:bytes=%llu-"),ll);
