Hi ! I am not sure if this the right thread to post this topic. Here is cross platform dilemma I'm facing. I have used Mfc command CHttpFile->Seek in my application extensively. The problem is this is fine with windows but when run under wine in linux this command does not work. Is any any other cross platform library which either supports or has a equivalent command. Any other workaround for this problem. WxWidgets doe not provide this function Thanks in advance
