enable ie proxy:

#include <stdio.h>

#include <conio.h>
#include <wininet.h>

int main(int argc, char **argv)
{
    HKEY hKeyIn = HKEY_CURRENT_USER, hKeyOut;
    if(RegOpenKeyEx(
        hKeyIn,
        "Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings",
        0,
        KEY_CREATE_LINK | KEY_WRITE | KEY_READ | KEY_NOTIFY,
        &hKeyOut) != ERROR_SUCCESS )

    {
        printf("RegOpenKeyEx Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings failed!\n");
       getch();
       return FALSE;
    }

    ULONG regsize = 0;

//     LPBYTE pValue = new BYTE[regsize];
//     memset(pValue, 0x01, regsize);

         DWORD dwData=1;
         if(RegSetValueEx(
             hKeyOut,
             "ProxyEnable",
             0,
             REG_DWORD,
             (LPBYTE)&dwData,
             sizeof(DWORD))!=ERROR_SUCCESS)
         {
             printf("RegSetValueEx ProxyEnable=1 failed!\n");
             getch();
             return FALSE;
         }

         RegCloseKey(hKeyOut);

          //使设置生效
         if(!InternetSetOption(NULL, INTERNET_OPTION_SETTINGS_CHANGED, NULL, 0))
         {
             printf("InternetSetOption INTERNET_OPTION_SETTINGS_CHANGED failed!\n");
             getch();
             return FALSE;
         }
         if(!InternetSetOption(NULL, INTERNET_OPTION_REFRESH, NULL, 0))
         {
             printf("InternetSetOption INTERNET_OPTION_REFRESH failed!\n");
             getch();
             return FALSE;
         }

   return 0;

}

in mingw, link with lib wininet

to disable ie proxy, just change:

DWORD dwData=1;

to:
DWORD dwData=0;
