Antonio, 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-N...

Antonio,

The GPF was caused by the WSAStartup() function. I removed it and I did not get the GPF. Is this function required?

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"

... de harbour tiene que haber la forma de asignar la variable cTemp de nuevo al buffer. En 16 bits lo hago asi: cTemp:=WSAData:Buffer rc:=WSAStartup(bin2i(chr(1)+chr(1)),@cTemp) WSAData:Buffer:=cTemp Ya que la data BUFFER es asignable (3ª línea), ...

Leandro:

Esta es la que yo utilizo:

Function IsInternet()

LOCAL cIp, cVret := .F.

WsaStartUp()

cIp := GETHOSTBYNAME("microsoft.com")

WsaCleanUp()

RETURN (cIp<>"0.0.0.0")

Una forma de hacerlo sin matar pulgas a cañonazos:

Function IsInternet()
WSAStartup()
RETURN (IIF(GetHostByName("microsoft.com")<>"0.0.0.0",.T.,.F.)

Grazie, ci provo!

Ricordati di mettere WSAStartup() prima e WSACleanUp() dopo.

Jeff,

You must add WsaStartup() before the call to Gethostbyname() and add a WsaCleanup() after the call.

Try this:

Function GetIP()
Local cVar1
WsaStartUp()
cVar1 := GetHostByName( GetHostName() )
WsaCleanUp()
return cVar1

Perdon por la Ignorancia pero
¿cuando es cuando debemos usar?

WSAStartup() y WSACleanup()

¿Es solo en Windows Mobile Verdad?
