May 31, 2011I am using the following code to enumerate through com ports to determine if the attached modems are in use.When I get to my usb modem, it returns the correct "PostIsAvailable" status, but then it kind of locks up the modem and I get the following error when I try to manually query the modem I get: "The modem failed to respond. Make sure it is properly connected and turned on. If it is an internal modem, or is connected, verify that the interupt for the port is properly set."I either have to manually requery the modem or unplug/plug it again.This code works fine on my external serial modem, but not the USB modem.

View 3 Replies[2008] Make Web Service Ports?
Feb 2, 2009I'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?

Mar 27, 2009I 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 RepliesDCOM With Limited Ports
Dec 1, 2011We 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.

Gathering Data From Several Different COM Ports And Reformat?
Apr 28, 2010I have written a program that will gather data from several different COM ports and reformat the data before sending it to a web site. This program is intended to run 24/7, but only send the information at user specified intervals. I have the routines to gahter data, but I only need it to perform this task at the specified time (5 minutes to each hour). At startup the dialog minimizes to the system tray. I would like a balloon message notifiy anyone watching that the data is about to be sent, and allow them to add additional comments if they choose (by clicking on the balloon). The system tray icon has several context menu items that the user may need. Is this the proper use of a background thread? I would also like opinions on the best method for pausing execution until the specified time.
