IPv4 - IPv6 - UPnP NAT - NAT Traversal Via Teredo
Jan 24, 2010
In the past I have written applications that communicate over the network. These have always made use of the System.Net and System.Net.Sockets classes and communicated over TCP connections. The connections have always required an IP address and a port. As these applications have been used by myself and colleages, setting up port forwarding and various other network settings has never been a problem. However, when developing an application for use by the general public, it obviously not a good idea to assume the user is capable of managing these settings.

I have the following code in VB 2008:
Public
Class Form1
Private[code]....
I am running this on my version of window 7 - my problem is that it is returning a IPv6 address and not a IPv4. I have searched and played around all evening to try and sort this out... to no avail.

I have a code which i need to translate from VB6 to VB.net. it gets the values from an array and check that all these values are present in DB also else give error
Set rs = db.OpenRecordset("select item from val")
If Not rs.EOF Then
For i = 0 To UBound(ArrayProc)
[CODE]............
I have a problem in converting this -
1. I am using visual studio , i dont know why it oraclereader doesn't has "HASROWS" METHOD.That i need to start my main IF condition
2. As you can see the rs is completely traversed as many times as number of elements in array. but with vb.net oracle reader if i use dr.read() function it will traverse only once.

I have been working on a number of card games. Important, of course, is shuffling the deck.I have come up with a few different ways to do this. Currently I do not shuffle, but to deal a card, I lay out the deck in order, selecting a random number between 1 and the number of cards remaining and selecting that card. I then remove that card from the deck so that another card can be picked.There are two main ways to do this, and I am trying to figure out which one is optimal.The first is to have an array of cards. When one card is dealt, a new array is formed with that card missing. I kind of like keeping the array size exactly the size of the deck, but perhaps this is not efficient. So, the first array has length n and the new array after the card is dealt has length n-1. VB.Net makes it simple to change array sizes around like this.

I was unable to register the related upnp.dll provided by the intel open source upnp tools package (as provided here:[URL] from the VB6 references dialog, it said something to the effect of "can't register .dll", but since it is written in (i think) C or C++ I figured there would be a way to make it useable somehow.I am mainly thinking of moving to intel's upnp because microsofts upnp.dll is not letting me progress further due to the following issue (works in .NET but not in VB6):[URL]how I would go about getting intel's upnp.dll (registers correctly in C# and VB.NET) to work in VB6?

How does the .NET regex string to extract IPv6 addresses look like ?I can get it to extract a simple IPv6 address like "1050:0:0:0:5:600:300c:326b" but not the colon format ("ff06:: c3");My problem is, it should extract a 0 for every omitted value between.[code]

I'm working on a type of p2p program, and I found the need to forward ports. That can get complicated for the average user, so I'm including the option to use UPNP to forward the ports for them. I'm using code I found HERE, and it worked too! then randomly it stopped working. I don't remember changing anything in the codeThis is the entire code. I have the Exception Highlighted in Red. The project includes a Listview (6 columns), three buttons (4, 5, 6), a progress bar, and a background worker.
Imports System.Net.Sockets

I'm trying to get the ip address of my local PC, and one one of my other PCs it gets the v4 address fine, but on this one the code:
Dns.GetHostEntry(Dns.GetHostName).AddressList(0).ToString()
returns what I guess is a IPv6 address:
fe80::9c09:e2e:4736:4c62%11
How do I get the IPv4 address?

I have the following code:
Dim ipAdd As IPAddress = Dns.GetHostEntry(strHostname).AddressList(0)
Dim strIP As String = ipAdd.ToString()
When I convert to String instead of an IPv4 address like 192.168.1.0 or similar I get the IPv6 version: fd80::5dbe:5d89:e51b:d313 address. Is there a way I can return the IPv4 address from IPAddress type?
