Thread: My program needs to read from a synchronized html file

You can probably get the actual file name for the cached page using GetUrlCacheEntryInfo (see the WinINet functions)

Then you just have to set up a schedule to synchronize the pages, which you can do through internet explorer by right-clicking your favorites item and clicking "make available offline" (that's one way, at least).

Thanks for the reply. These functions do look useful, except I'm kind of new to these Wininet functions. I think I got the point that this is a BOOL function and it will return true or false (not sure what to do with that result) and that I'm supposed to include a structure with all the information declared that the function will get. But I'm gettin some compile errors and I'm wonderin if someone could show me generally how the program should be structured or show me a website that tells me so I know I'm doin it right. Also, I'm not 100% on how I can access these variables inside the struct, and what are the necessary headers? Thanks in advance guys, and hopefully soon I'll be able to get a grasp on this internet stuff..

I've only used a couple of the WinINet functions before, but I found a page on msdn that gives an example of GetUrlCacheEntryInfo(and other cache functions)
And I went ahead and tried it out myself. This seems to work alright for me:

Code:

  LPINTERNET_CACHE_ENTRY_INFO cei; 
      DWORD dwSize = 0;
      if(!GetUrlCacheEntryInfo("http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/system_error_codes__0-499_.asp",NULL,&dwSize))
      {
        if(GetLastError()==ERROR_INSUFFICIENT_BUFFER)
        {
          //just need to allocate correct buffer size
          cei = (LPINTERNET_CACHE_ENTRY_INFO)new char[dwSize];
          cei->dwStructSize = dwSize;
          //try again
          if(!GetUrlCacheEntryInfo("http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/system_error_codes__0-499_.asp",cei,&dwSize))
            MessageBox(NULL,"Could not retrieve cache entry info","Error",MB_OK);//handle error
          else //if successful, print out filename
            MessageBox(NULL,cei->lpszLocalFileName,"Cache entry file:",MB_OK);
        }
        else
          MessageBox(NULL,"Could not retrieve cache entry info","Error",MB_OK);//handle error
      }

My only guess is that the website is stored in the cache under a different name.

You might try using InternetOpen, InternetOpenUrl, and InternetReadFile instead. I believe that InternetOpenUrl will actually open the cached file anyways if you specify the correct flag.
