    Howto change an url on the DLL?

    Good evening, I'm not experienced in C+ programing in fact I'm a retired man but a computer lover. I was using the SpanishProvider.dll that fech information from Filmaffinity web but has changed the url from www.mobile.filmaffinity.com/es to www.m.filmaffinity.com/es/main.php , I tried to change it with several programs Visual Studio, Boomerang win32, etc) but for me it's impossible.
    I have not the source because the developper is missing.
    My question is if possible to modify the url on the DLL w/o the source.
    Thanks in advance, every answer will good for me , I'm really desperate.
    Regards

    Maybe you could contact the owners of filmaffinity.com and ask them to add a mapping to their webserver to redirect requests to www.mobile.filmaffinity.com/es to www.m.filmaffinity.com/es/main.php? Assuming what this DLL is doing is legal and permitted by the website, that would be the easiest way to go here.

    Thanks to replay rags_to_riches , 2 weeks ago I contacted with web asking to redirect request but I have not answer from web. Too I tried to modify in the local computer (I'ts a Mediacenter box) to direct the request but neither host file or modifying the ADSL Router it's possible becaus the domain IP it's the same, only has changed the url link.

    About my question...with Microsoft Visual C I can see the code lines with the old URL that I would need change, but I can't edit it. It's any way to change it or it's more complex because I have not the source?

    I'm not sure how you would use Visual C, or Boomerang, to do what you are talking about. Just use a hex editor. The problem is, the new string seems to be a bit longer than the old one, so you might have to do something weird like create a TinyURL link and then use that instead (since you can't replace the string with something longer than what's already there).
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}

    My initial thought would be to use a local proxy to redirect www.mobile.filmaffinity.com/es to www.m.filmaffinity.com/es/main.php automatically.

    But this relies on you being able to configure a proxy in your application.

    Some suggested proxies
    HoTTProxy - the Open Source HTTP Proxy
    Privoxy - Home Page
    Acme Consulting -Società di Consulenza e Formazione Informatica - Torino
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Brewbuck, I thought to myself the way to change the url lines was using the original tool was created (Visual C), but from your answer is not need it (or not useful).
    Will the 1st time using the UltraEdit but I'll it.

    Salem, that was an idea but I discard it because I thought that only works from URL asked from web browser but not from external way as a DLL.
    I'll try it too. Thanks a lot to asnwer

    FWIW, the DLL appears to be a .NET DLL, which means you could use something like .NET Reflector to decompile it, change the contained strings, and recompile it.

    The file seems to have exactly four UCS16 strings in it, at decimal offsets
    Code:
    16398: http://api.themoviedb.org/2.1/Movie.search/en/xml/{1}/{0}
    16514: http://api.themoviedb.org/2.1/Movie.getInfo/en/xml/{1}/{0}
    16783: http://mobile.filmaffinity.com/es/search.php?stext={0}&stype=title
    16917: http://mobile.filmaffinity.com/es/moviesynop.php?id={0}
    You could do a simple binary replacement using strings of the exact same length, i.e.
    Code:
    16783: http://m.filmaffinity.com/es/search.php?stext={0}&stype=title&&&&&
    16917: http://m.filmaffinity.com/es/moviesynop.php?id={0}&&&&&
    but while the former seems to work (e.g. http://m.filmaffinity.com/es/movie.php?id=988464&&&&&), the latter does not (e.g. http://m.filmaffinity.com/es/moviesy...id=988464&&&&&).

    In other words, the FilmAffinity site has been modified in a way that almost certainly breaks your library in other ways, too.

    Thanks Nominal Animal, I thought it could easier but is getting a nightmare for me. Every modfification I do with Hexadecimal editor or .NET Reflector breaks the DLL and not working with the program.
    Finally I throw in the towel.
    Thanks a lot to everybody, you're a great team
