Do you wan't to disable internet access completely or just block some programs?

The easiest way has to be to install ZoneAlarm or similar software. ;)

Nooo... i want to disable my internet connection with program made by C++. Not by software that you said above... :)
Problem is i can't see the function in MSDN library to disable internet connection.

IMO you can't block internet connection. But you can try to block every program that asks for internet connection.

You can disable your NIC (Network Interface Card).

Here is an example (The code could use some work/error checking but it's a start for you).


#include <netcon.h>

void DisableNIC(char* InterfaceName)
{
INetConnectionManager* pNet;
INetConnection* pConn;
IEnumNetConnection* pEnum;
NETCON_PROPERTIES* pProps;
wchar_t Temp[255];
ULONG uCount = 0;

swprintf(Temp, L"%S", InterfaceName);
CoInitialize(NULL);
CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, IID_INetConnectionManager, (void**)&pNet);
pNet->EnumConnections(NCME_DEFAULT, &pEnum);

while (pEnum->Next(1, &pConn, &uCount) == S_OK)
{
pConn->GetProperties( &pProps );
if (!wcscmp(pProps->pszwName, Temp))
{
printf("Found %S\n", pProps->pszwName);
printf("Going to disable connection now!\n");
pConn->Disconnect();
printf("Disabled!");
CoTaskMemFree(pProps->pszwName);
CoTaskMemFree(pProps->pszwDeviceName);
CoTaskMemFree(pProps);
pConn->Release();
}
}
pEnum->Release();
pNet->Release();
CoUninitialize();
}


Example: DisableNIC("Local Area Connection");

This code will 'disable an internet connection' - is it what you are looking for?#include "IpExport.h"
#include "Iphlpapi.h"
#pragma comment(lib,"iphlpapi")

...

// Call GetInterfaceInfo() with empty buffer to get the required size.
ULONG ulInfoLength = 0;
::GetInterfaceInfo(0,&ulInfoLength);

// Allocate buffer for PIP_INTERFACE_INFO
LPBYTE pInfoBuffer = new BYTE[ulInfoLength];
PIP_INTERFACE_INFO pInfo = (PIP_INTERFACE_INFO)pInfoBuffer;

// Call GetInterfaceInfo() with valid buffer to get the actual data
::GetInterfaceInfo(pInfo,&ulInfoLength);

// Release adapters
for( LONG i=0; i<pInfo->NumAdapters; ++i )
::IpReleaseAddress(&pInfo->Adapter[i]);

// Delete the IP_INTERFACE_INFO buffer
delete [] pInfoBuffer;

I have question : what is mean "::" in front of IpReleaseAddress, etc. I never used it, but if i'm download source code, many of them use this....

Thanx 4 clear me... i just wanna to make my brother angry coz this thing.... :cool: and i think this is coolll.... :)

It says that this variable is declared in the global namespace, not in the current one.
