Select

Project ->settings ->Link

Enter "hd415.lib hm415.lib ws2_32.lib" at the beginning of the "Object/library modules" line.

thank you for your reply!

I link the lib,but there are still three errors.I don't know what is wrong?

Is it because there is not the enough space or the ASTER HDF file is not in the place same to the VC++?

thank you !

Hi,wyjxy1979



These are Winsock functions.Ws2_32.lib should be included in your

project "setting"->"link"->Library option.



Good Luck!
