View 3 RepliesI'm making an application that tracks jobs we log in our IT department and as I'm often out and about it would be handy to be able to use this app from my laptop and connect in to our server at our office. The problem is that a lot of the places I go block all outboundtraffic apart from port 80 and 443 (for HTTP and HTTPS). Now I know I could write an ASP.NET front end that I could just access over the internet but to be honest I just plain dont like making ASP.NET web pages and so if there is any way I could do this just through my standard desktop app that would be good.
I've heard a bit about "web services" and to me this sounds like a solution but I dont know enough about them to decide if I should use one or not.The main thing that will decide this is whether or not I can make this web service listen on port 80, is that possible?Also, is it hard work making something use HTTPS instead of HTTP so that the data is encrypted? I mean, do you have to do all of the encrypting yourself or is there some sort of automatic function you can use to handle this?

View 3 RepliesI have been stumped on this for about 3 weeks now. In the beginning me and my partner have been trying to hit this at the internal angle. only problem is different html tables are constructed different than others. We are needing to extract from multiple pages and sites so we know that Regex will be the best solution. We can use the same script for everything. This is my first time working with Regex, I got it actually extracting the very first ip[proxy]. I have no idea why it isn't extracting every one on the page. I also have to add the . in between each each octave of the ip. That is weird because I have it in the Regexpession to find the .'s.What I'm Needing is for this to basically scan the whole page and grab all the ipsorts and add them to a listbox.Here is my

View 1 RepliesWe need to put a firewall in between our servers and a couple of clients. To do this we need to limit the number DCOM ports available so that we know what ports to open on the firewall.The question I have is do we need to limit the number of ports on all the machines inside the firewall as well as outside. This would cause an issue as we have lots of machines which would need to be modified.If DCOM has the intelligence to negotiate on port 135 which port is available on both machines which need to communicate, we will only need to modify the 2 machines on the outside of the firewall.
