Unless your router has a specific means of requesting that information (I know of none that do) you have to go outside the WAN and come back in. There's several sites out that perform this like http://www.talkswitch.com/wap/checkip.php[^], http://www.historians.org/HistoryCoop/IPCheck.cfm[^] or http://ip.discoveryvip.com/[^] PeterRitchie.com

I guess the problem is because you're calling methods/setting properties on the control from another thread. You should use BeginInvoke or Invoke methods on the UI (the Form object in your case) to marshal the call to the UI thread.

I've done some more research and it appears the problem is caused using timers. I've used both System.Timers.Timer and System.Windows.Forms.Timer and both give the same result, a black box that appears and then disappears. If I call the ShowPopup subroutine by clicking a button, it displays correctly. If the timer causes the form to be displayed, I get the black box. Here's the logic steps used: 1) Timer.Tick event occurs 2) Tick Handler creates a new AsyncUpdater and invokes the GetUpdate method 3) GetUpdate creates a new thread and begins the remoting call 4) Once GetUpdate has completed the remoting call, the event RetrieveDone is raised. 5) The main form handles the event causing a list view to update it's list of items. 6) The ShowPopup method is called to display the popup. Any help or ideas would be greatly appreciated. I can't understand why the manual invoking (pressing a button) works but the event handler doesn't. Thanks!

If you are getting the "Can't create Activex Component" error is because you either: a. did not register the component for COM use b. did not copy the component to the same directory where the calling program is located. All the information you need is found in the resources already mentioned by other people.

So long as the target machine has the appropriate version of the .NET Framework installed, this will work. Once the component is registered, it works just like any other COM component. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

I went back and checked other applications and I found the same problem. It just seems to be a server button control that handles a click event.

Passing objects byref is pointless 99% of the time. You do not need to pass byref in order to be able to modify the object properties. It is the most misused keyword in VB, which is why the VB.NET team switched the default from ByRef to ByVal. my blog

Yeah, they snuck this in on VS.2003 (.NET 1.1) and I was one that moved later from VS.NET 2002 to VS.NET 2003. After the change I noticed my www.HintsAndTips.com site failing out when posting tips. I use <LINK> and <FIX> for hyperlinks and Fixed text blocks in the tip postings. Once I found what they did to prevent me from shooting my own foot I could finally deal with it. Just wish they would have had a bit more content to their error message so you knew what it was referring to without spending hours finding out. For me I spent the time trying to see in my code how it could be failing and trying to figure out why I got the error only at certian times until I noticed it was when I was using tags ;) Rocky <>< www.HintsAndTips.com - Now with GMail Queue www.MyQuickPoll.com - 2004 Election poll is #33 www.GotTheAnswerToSpam.com "We plan for the future, we learn from the past, we live life in the present!"

Your specific question was about how to decouple your objects from the method used to persist them (database, web service, etc). This can be achieved in many ways, so I am uncomfortable recommending a specific approach without knowing more about your environment. The books I mentioned (esp. P of EAA) cover the subject in detail, but they are not light reading, so I am not sure that they would help. There are some articles on this site, in the Design and Strategy section that may help. If you can find a good systems architect, that would probably be your best bet. my blog
