am very much new to windows currently trying to port a linux project to windows.

My application has an option to change IP-subNet-Gateway of the system with some search i was able to fina an API to it in C way

but the below mentioned works well with XP but win 7 it does not reflect.

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <winsock2.h>
#include <iphlpapi.h>
#include <stdio.h>
#include <tchar.h>
typedef long _stdcall (*inpfuncPtr)(char *szAdapterGUID,
                                            DWORD dwDHCP,
                                            DWORD dwIP,
                                            DWORD dwMask,
                                            DWORD dwGateway);



int main(void) {
    HINSTANCE hLib;
    inpfuncPtr in;
    char c;

    hLib = LoadLibrary(TEXT("iphlpapi.dll"));
;
    if (hLib == NULL)
    {
        printf("LoadLibrary Failed.\n");
        return -1;
    }
    in = (inpfuncPtr) GetProcAddress(hLib, "SetAdapterIpAddress");
    if (in == NULL)
    {
        printf("GetProcAddress for SetAdapterIpAddress Failed.\n");
        return -1;
    }
    PWSTR pszGUID = NULL;
    char  szGUID[] = "{6FD68F0D-4656-4428-AF32-E877FA6C1721}";
    DWORD dwSize = 0;

    WideCharToMultiByte(CP_ACP, 0, pszGUID, -1, szGUID, sizeof(szGUID), NULL, NULL);

    in(szGUID,
                            0,
                            inet_addr("192.168.10.248"),
                            inet_addr("255.255.255.0"),
                            inet_addr("192.168.10.1"));


    printf("OK oK.\n");
    return 0;
}
