Hi all mister,

1. detect Network



2. detect Internet Connection is working...


which is the best way in the world and good practice recommended by MVPs
Microsoft ?

Thanks in advanced..



code below...but which is the best code ???



NetworkInterface.GetIsNetworkAvailable()



private static int ERROR_SUCCESS = 0;
public static bool IsInternetConnected() {
long dwConnectionFlags = 0;
if (!InternetGetConnectedState(dwConnectionFlags, 0))
return false;

if(InternetAttemptConnect(0) != ERROR_SUCCESS)
return false;

return true;
}


[DllImport("wininet.dll", SetLastError=true)]
public static extern int InternetAttemptConnect(uint res);


[DllImport("wininet.dll", SetLastError=true)]
public static extern bool InternetGetConnectedState(long flags,long
reserved);



Correct translation below.

[DllImport("wininet.dll", SetLastError=true)] public static extern bool
InternetGetConnectedState(out int flags,int reserved);


I found code in C#,



HttpWebRequest req;
HttpWebResponse resp;
try
{
req = (HttpWebRequest)WebRequest.Create("http://www.google.com");
resp = (HttpWebResponse)req.GetResponse();

if(resp.StatusCode.ToString().Equals("OK"))
{
Console.WriteLine("its connected.");
}
else
{
Console.WriteLine("its not connected.");
}
}
catch(Exception exc)
{
Console.WriteLine("its not connected.");
}
