The print statement below says that 0 bytes were read, but that there was wxURL_NOERR. I think there is a website that will tell you what webserver is used for any given site, maybe there's something off with their server? function iff(a, b, c) if a then return b else return c end end function HTTP_GET(URL) local T = {} local U = wx.wxURL(URL) -- Make local local S = U:GetInputStream() local i = 1 while S:CanRead() do a = S:Read(64) print(string.format("%d: %d : %d : Err %d : '%s'\n", i, S:LastRead(), iff(S:Eof(), 1, 0), U:GetError(), a)) table.insert(T,a) i = i + 1 if i == 10 then break; end end return table.concat(T), T end Regards, John Labenski ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ wxlua-users mailing list wxlua-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wxlua-users
