Darrell,
If you mean local network, then you may check for a file existence:
if File( "\machine\path\filename" )
For Internet access, you may use:
Function IsInternet()
WSAStartup()
RETURN GetHostByName( "www.microsoft.com" ) != "0.0.0.0"
Thank you Antonio
Antonio,
I got a FWPPC GPF occurred. Fix GPFStack() when using IsInternet function below.
Antonio,
The GPF was caused by the WSAStartup() function. I removed it and I did not get the GPF. Is this function required?
Darrell,
Is IsInternet() working without it ?
Hi Antonio,
No, it returns IP 0.0.0.0; however the internet is working and my FWPPC application sees host \cargo\data. Should GetHostByName() use 'cargo' or '\cargo'?
Thank you,
"\\" is just for other machines on the LAN.
Please add this code to your PRG:
Please add this code to your PRG:
#pragma BEGINDUMP
#include <hbapi.h>
#include <WinSock2.h>
HB_FUNC( WSASTARTUP )
{
static WSADATA wsa;
hb_retni( WSAStartup( 0x202, &wsa ) );
}
#pragma ENDDUMPAntonio,
Got the following error when trying to build application.
FiveCEC.lib(WINSOCK.obj) : error LNK2005: HB_FUN_WSASTARTUP already defined in CDM-NET.obj
FiveCEC.lib(WINSOCK.obj) : warning LNK4006: HB_FUN_WSASTARTUP already defined in CDM-NET.obj; second definition ignored
Creating library CDM-NET.lib and object CDM-NET.exp
CDM-NET.exe : fatal error LNK1169: one or more multiply defined symbols found
Darrell,
use this flag for link.exe: /force:MULTIPLE
Antonio,
I am getting a fatal application error.
Darrel,
What FWPPC build are you using ? Please tell me the dates of the libraries, thanks

Darrell,
This Test.prg works fine here with no GPFs. Please try it, thanks:

Hello Antonio,
this solution is working but if there is no network you get for a very long time a frozen systembefore an error is returned.
Many useres press the reset button because they think the system is gone down.
Maybe there is a better solution?
Thanks in advance
