COCOS2DX C + + some practical methods __c++

1. Get GUID

Const char* NewGuid ()
{
     static char buf[64] = {0};
     GUID guid;
     if (S_OK =:: CoCreateGuid (&guid))
         {
          _snprintf (buf, sizeof (BUF)
            ,%08x-%04x-%04x-%02x%02x-%02x%02x %02x%02x%02x%02x "
            , GUID. Data1
            , GUID. Data2
            , GUID. Data3
            , GUID. Data4[0], GUID. DATA4[1]
            , GUID. DATA4[2], GUID. DATA4[3], GUID. DATA4[4], GUID. DATA4[5]
            , GUID. DATA4[6], GUID. DATA4[7]
            );
         }
     return (const char*) buf;
}

2. Get the current time stamp

std::string getrawtime () {
    SYSTEMTIME systime;
    Getlocaltime (&systime);
    time_t Unixtime;
    Time (&unixtime);
    std::string rawtime = __string::createwithformat ("%ld%ld", Unixtime, Systime.wmilliseconds)->getCString (); Output UNIX timestamp string
    rawtime.erase (a);
    return rawtime;
}

3. Get file Timestamp

time_t tt;
struct TM *tst;
struct STAT st;
Stat ("D:\\simple.txt", &st);/must use two ' \ '
tt = st.st_ctime;
Log ("tt=%ld\n", TT);

4. Compressed Files

Zip library download link http://download.csdn.net/detail/chinawallace/9584122
hzip Hz = Createzip (L "C:\\simple1.zip", 0);
Zipadd (Hz, L "Simple.txt", L "C:\\simple.txt");
Closezip (Hz);

5. Get Network status

#include <Sensapi.h> 
#pragma comment (lib, "Sensapi.lib")
DWORD flags;
Isnetworkalive (&flags);

6.COCOS2DX Fetch Local Data stream

ssize_t size = 0;
unsigned char* Titlech = fileutils::getinstance ()->getfiledata ("D:/test.png", "R", &size);          

7.COCOS2DX Load network picture data stream

Const char* PSRC = "Network picture data stream";
    unsigned char *pdata = (unsigned char*) (const_cast<char*> (PSRC));
    Auto Pdatalen = strlen ((const char*) pData);

    std::string load_str;
    Load_str = std::string ((const char*) pData, Pdatalen);

    int len = 0;
    unsigned char *buffer1;
    Len = Base64decode ((unsigned char*) load_str.c_str (), (unsigned int) load_str.length (), &buffer1);

    image* img = new Image ();
    bool OK = Img->initwithimagedata (buffer1, Len);

    unsigned char *pngdata = Img->getdata ();

    Cctexture2d *texture = new Cctexture2d ();
    Texture->initwithdata (Pngdata, Img->getdatalen (), kcctexture2dpixelformat_rgb888,
        img->getWidth (), Img->getheight (), Ccsizemake ((float) img->getwidth (), (float) img->getheight ());
    Sprite->initwithtexture (texture);

8.COCOS2DX Generate JSON

#include "json/document.h" #include "json/writer.h" #include "json/stringbuffer.h" #include <iostream> #include

Data/httpconstant.h "using namespace Rapidjson;
Generate JSON Rapidjson::D ocument m_writedoc; M_writedoc.
SetObject (); Rapidjson::D ocument::allocatortype& allocator = M_writedoc.
Getallocator ();
Rapidjson::value object (Rapidjson::kobjecttype); M_writedoc.

Removeallmembers ();
Rapidjson::value Gradeid (Rapidjson::kstringtype);
Gradeid.setstring ("45014d74cce3469b86ace39cf2025de6", allocator); Object.

AddMember ("Gradeid", Gradeid, allocator);
Rapidjson::value validation (Rapidjson::kstringtype); Validation.
SetString ("123", allocator); Object.

AddMember ("Validation", validation, allocator);
StringBuffer buffer;
Rapidjson::writer<stringbuffer> Writer (buffer); Object.
Accept (writer); std::string strsendmessage = buffer.

GetString ();
Parse JSON Rapidjson::D ocument writedoc; Writedoc.
SetObject (); Rapidjson::value &value = Writedoc. Parse<kparsedefaultflags> (Str.c_str ()); BOOL result = value["result"]. Getbool ();

9.COCOS2DX HTTP requests

#include "network/httpclient.h" using namespace network;
httprequest* request = new (Std::nothrow) HttpRequest ();
Request->seturl ("Http://192.168.1.7:8080/lesiea/game/drumsData");
Request->setrequesttype (httprequest::type::P ost);
Request->setresponsecallback (Cc_callback_2 (courseselectclassa1layer::onhttprequestcompleted, this));
std::vector<std::string> headers; Headers.push_back ("Content-type:application/json;
Charset=utf-8 ");

Request->setheaders (headers);
Request->settag ("test");
Httpclient::getinstance ()->send (request);

Request->release (); void onhttprequestcompleted (Cocos2d::network::httpclient *sender, Cocos2d::network::httpresponse *response) {if (!re
    Sponse) {return;
    Long StatusCode = Response->getresponsecode ();
    Log ("Response code:%LD", StatusCode);
        if (StatusCode!=) {log ("response failed");    

        Log ("Error buffer:%s", Response->geterrorbuffer ()); Auto Layer = Tiplayer::cReate ("Get the class two-dimensional code failed");
        This->addchild (layer, 100, 100);
    Return
        else {std::string tag = response->gethttprequest ()->gettag ();
        std::vector<char> *buffer = Response->getresponsedata ();
        std::string str;
        for (unsigned int i = 0; i < buffer->size (); i++) {str = (*buffer) [i];
    } log ("%s", str); }
}

10. Random list data

Random generator function:
ptrdiff_t myrandom (ptrdiff_t i) {return rand ()% i;}
Pointer object to it:
ptrdiff_t (*p_myrandom) (ptrdiff_t) = Myrandom;
Srand (unsigned (NULL));////s random number seed
//using Myrandom:
random_shuffle (M_userinfovector.begin (), m_ Userinfovector.end (), p_myrandom);

11. Get Network Connection Status

#include <Sensapi.h> 
#pragma comment (lib, "Sensapi.lib")

DWORD  flags;//Internet way   
BOOL  m_ Whether the bonline=true;//is online    
m_bonline=isnetworkalive (&flags);    

if (m_bonline)//online    
{    
   if ((Flags & Network_alive_lan) ==network_alive_lan)  
   {  
    cout<< " Online: network_alive_lan\n ";  
   }
   if ((Flags & Network_alive_wan) ==network_alive_wan)   
   {  
    cout<< "online: network_alive_wan\n";  
   }  
   if ((Flags & Network_alive_aol) ==network_alive_aol)    
   {    
    cout<< "online: network_alive_aol\n";   
   }    
}  
else   
   cout<< "not on line \ n";    
}  

12. List Random Sort

Random generator function:
ptrdiff_t myrandom (ptrdiff_t i) {return rand ()% i;}

Pointer object to it:
ptrdiff_t (*p_myrandom) (ptrdiff_t) = Myrandom;

Srand (unsigned (NULL));////s random number seed
        //using Myrandom:
        random_shuffle (M_userinfovector.begin (), m_ Userinfovector.end (), p_myrandom);
        for (int i = 0; i < m_userinfovector.size (); i++)
        {
            m_userinfovector.at (i)->setindex (i+1);
            m_pheadvector.at (i)->initwithfile (m_userinfovector.at (i)->getusericon ());
        }   

13.c++ Split substring

std::string tag = "Save12";
std::string str = "Save";
if (Strstr (Tag.c_str (), Str.c_str ()))
{
    std::string s = tag.substr (4);
}

14. Read local data stream

 ssize_t size = 0;

    unsigned char* Titlech = fileutils::getinstance ()->getfiledata (Path, "rb+", &size);

    Auto Pdatalen = strlen ((const char*) Titlech);
    Std::string load_str;
    Load_str = std::string ((const char*) Titlech, Pdatalen);

    Log ("data=%s", Load_str.c_str ());

    Std::string load_str;
    Auto data = Fileutils::getinstance ()->getdatafromfile (path);
    unsigned char* Titlech = Data.getbytes ();

    Auto Pdatalen = strlen ((const char*) Titlech);
    Load_str = std::string ((const char*) Titlech, Pdatalen);

    Log ("data=%s", Load_str.c_str ());

    FStream Fsin;
    Char s[65535];

    Fsin.open (Path.c_str (), ios::in | ios::binary);
    Fsin.read (S, 65535);

    Fsin.close ();
    char* C = s;
    std::string str = c; Log ("%s", Str.c_str ());
