<![CDATA[
Title: Get / set global offline State?
{
Users can choose to work offline by selecting Work Offline on the
File menu in Internet Explorer 4.0 and later. When Work Offline is selected,
the system enters a global offline state independent of any current network
connection, and content is read exclusively from the cache.
}
uses wininet;
// Get offline state
// Alhaiseb Misurata Libya
function IsGlobalOffline: Boolean;
var
State, Size: DWORD;

Result := False;

Size := SizeOf(DWORD);
if InternetQueryOption(nil, INTERNET_OPTION_CONNECTED_STATE, @State, Size) then
if (State and INTERNET_STATE_DISCONNECTED_BY_USER) 0 then

end;
//Set offline state
