   IF InternetGetConnectedState( @n, 0 ) == 0
      LB_Warning('The system can not check and download updates, because there is no connection to the Internet!', '(C) Eidos-X++ System"')
      RunShell("",executable_module.exe,.T.)
      RETURN NIL

I use Boris Borzic's Xb2NET. I have Alaska 1.9. Maybe there's something like that in Alaska 2.0. I don't know. But I suppose there should be.

Code: Select all

DLLFUNCTION InternetGetConnectedState( @nFlags, nReserved ) USING STDCALL FROM WinInet.Dll

[/size]I have everything working perfectly: http://lc.kubagro.ru/__AIDOS-X.txt. I bought xb2net and several times consulted with Boris. He really, really helped me. Now I can do what I need in Alaska on the Internet.

Hi,

I use Microsoft's Network List manager API... https://docs.microsoft.com/en-us/window ... anager-api

Originally just to check for Internet Connection but modified the function to check for either network or internet connections. The MS site lists a number of other methods as well.

Code: Select all

FUNCTION NetworkConnected(pType)
LOCAL lConnected := .F.,;
      oNLM

#define CLSID_NetworkListManager "{DCB00C01-570F-4A9B-8D69-199FDBA5723B}"
#define NLM_CONNECTIVITY_IPV4_INTERNET     0x0040

   pType := IF(pType==NIL,"I",UPPER(pType))

   oNLM:= CreateObject( CLSID_NetworkListManager )

   IF pType == "I"
      lConnected := oNLM:IsConnectedToInternet()
   ELSEIF pType == "N"
      lConnected := oNLM:IsConnected()
   ENDIF

   oNLM:destroy()

RETURN lConnected

If connected the result is returned quickly however if not connected appears to take "a while".

Regards... Jonathan

InternetGetConnectedState works fine with Xbase++.

There's an eXpress++ sample in \exp20\samples\taskbar\taskbar.prg.
