    यहाँ मेरा कोड है 

      #include & lt; iostream & gt; # शामिल & lt; Windows.h & gt; #include & lt; WinInet.h & gt; नेमस्पेस एसटीडी का उपयोग करना; Int main () {HINTERNET h सत्र, एचएआरएल; Char * बफर = नया चार् [1024]; DWORD बफ़र लैन, बाइट्स लिखित; हैंडल फ़ाइलहैंडल; hSession = InternetOpenA (शून्य, 0, शून्य, शून्य, 0); hURL = InternetOpenUrlA (h सत्र, "http://www.google.co.uk", NULL, 0, 0, 0); FileHandle = CreateFileA ("सी: \\ temp.txt", GENERIC_WRITE, FILE_SHARE_WRITE, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, 0); बाइट्सड्राफ्ट = 0; करना {InternetReadFile (hurl, बफर, 1024, और बफ़र लैन); लिस्टफाइल (फाइलहाण्डल, बफर, बफ़र लें, और बाइट्स लिखित, नल); } जबकि (बफर लैन! = 0); CloseHandle (filehandle); InternetCloseHandle (उछालना); InternetCloseHandle (hSession); शेलएक्सिक्यूटेए (0, "ओपन", "सी: \\ temp.txt", नल, शून्य, 1); Cout & lt; & lt; "ऑपरेशन पूर्ण!"; प्रणाली ( "रोकें"); वापसी 0; }   
     यहाँ त्रुटियां हैं I  
      त्रुटि LNK2019: अनसुलझे बाहरी प्रतीक __imp__InternetOpenA @ 20 समारोह में संदर्भित _main त्रुटि LNK2019: अनसुलझे बाहरी प्रतीक __imp__InternetCloseHandle @ समारोह में संदर्भित _माइन त्रुटि LNK2019: अनसुलझे बाहरी प्रतीक __imp__InternetOpenUrlA @ 24 समारोह में संदर्भित _main त्रुटि LNK2019: अनसुलझे बाहरी प्रतीक __imp__InternetReadFile @ 16 समारोह में संदर्भित _main   
     मुझे समझ में नहीं आता कि मैं कहाँ हूँ गलत हो रहा। मैंने Wininet.h और Windows.h आयात किया है। इन कार्यों का पता लगाने में अभी भी समस्या क्यों है? सादर।   
     
     
     आपने जो किया है वह हैडर फ़ाइल शामिल है, लेकिन वास्तविक कोड से जुड़ा नहीं है जो लागू करता है

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177
