hello. Sorry for the long post. My ultimate goal is to make a program that can read text off a website, if told the url, when to start reading, and where to stop, and then write the text to a textfile. This is all easy once I am able to read the source code of the html doc given its url. Sooooo... I found this code from Planet Source Code, it claims to be able to read source code of a given url. A couple people responded to it, one person said they couldnt get it to work, another person said it worked great, so I think it probably works. But I am in the camp that cannot get it to work. I make a normal win32 app and in properties i select Use Shared MFC dll. This makes the CString opperations work but the other ones such as CInternetSession do not work, they give me errors of CInternetSession undeclared identifier. I remembered to put in #include <afxinet.h> so i dont understand what is wrong. Can someone please help a newbie??? Here is the code:

imple example of how to
