I want my app to be a Dynamic DNS client so that they don't have to run a separate app. From the documentation for the client all I need to do is goto a specific website and pass all the information on the command line. e.g. If I use IE and enter http://dynupdate-no-ip.com:PORT/ducupdate.php?username=EMAIL&pass=PASSWORD&h[]=HOST1 it actually updates the entry for my host. I figure that I should be able to use some simple internet component like TcpClient but I continually get a Socket Error 10049. What component should I use to send this information? Since it is such a simple requirement it doesn't seem like I should need the Indy Direct components. I figure I should be able to use one the built-in components for D6. Am I on the wrong track? Can anybody suggest how I should be doing this? Many thanks Richard Back to top Remy Lebeau (TeamB) Guest Posted: Thu Dec 04, 2003 11:26 pm    Post subject: Re: How can I do this?

HTTP is not a very trivial protocol to implement manually. Oh sure, you could send a few strings over the socket manually, but using a true implementation of the actual HTTP protocol is best.

I went to the Indy site to check out the licence thing and find it a little confusing as I do not plan to change the source code, I just want to use the component. My boss says that he doesn't want to have to list the attribution so I am looking at the Mozilla Public Licence. Can you tell me in simple terms, if I am just planning to use the component with no changes and do not want to distribute source code, what do I need to do? In '3.6 Distribution of Executable Versions' it looks like I still need to include a notice stating that the source code is available so there is still the attribution thing.

Quote: Can you tell me in simple terms, if I am just planning to use the component with no changes and do not want to distribute source code, what do I need to do? Simply write the program, put the component into the program, compile, and run. Quote: it looks like I still need to include a notice stating that the source code is available so there is still the attribution thing. I know nothing about how the licensing works. You will have to ask the Indy people directly. They have their own newsgroups at news.atozedsoftware.com.
