Hi All!
I am developing an application for release in early November (so time is critical). I am attampting to use the "InternetCheckConnection" function within WININET.DLL to detect the presence of an active Internet connection. Using the code below, I can never get a positive indication, even when IE is online and connected to the specified URL.
I am working in VFP 6.0, and any help would be much appreciated, especially if there is another way to positively detect an Internet connection without recourse to WinSock (this is needed to differentiate between a modem connection and a LAN connection).
Thanks
Terry Bridges

MessageBox ('Connection was Successful')

OTHERWISE
MessageBox ('Connection Error: '+ LTRIM(STR(lnreturn)))
ENDCASE
RETURN lnreturn
