The error is "An address incompatible with the requested protocol was used."

During development, we usually use localhost as the hostname, like the following
Dim serverListener As New TcpClient("localhost", 8585)
I want the user to be able to enter their IP address via a TextBox instead, like
Dim serverListener As New TcpClient(textbox1.text, 8585)
However, this is not working for me.

The problem is that I'm running on Windows Vista and the above code seems to want to return the IP V6 information and not the V4 information. How can I force it to return the V4 information?

I have a .Net program that has to run on a cluster of server 2008. To find out the right IP I resolve the dns by GetHostEntry(VarDefinedInfConfig).AddressList(0)
but when I am converting my old code (this code picks the wrong IP) dns.GetHostName().AddressList(0) => this returns a virtual IP and not the right one.So I changed my TcpListener to (dns is parameter from config)Dim listener As TcpListener = New TcpListener(New IPEndPoint(Net.Dns.GetHostEntry(dns).AddressList(0), 8001))
listener.Start()

With XP set to a language such as Spanish (Spain), the VBA-in-Excel function "Excel.Version" returns the text string "11.0" (not "11,1"). It does not respect the language setting.
"CLng(Excel.Version)" then produces the value "110" (wrong!), perhaps because CLng respects the language setting and is looking for a comma instead of a period.
The work-around is easy. But I need to know if switching to another language requires a setting that my client in Spain missed, or is this just a bug.
If it is a bug, is the problem limited to this one function (Excel.Version), or are there other functions that return values in text format that are affected?

I'm using a SQL Server 2008 stored procedure to create a new record with this syntax:
cmd.Parameters.Add("@photo", DBNull.Value)
cmd.ExecuteNonQuery()
but the result is a:
Operand type clash: nvarchar is incompatible with image
Photo is not the only parameter but is the only image one, I am not passing a nvarchar but a null value, am I missing something?

Why does this:Private [Function] As Func(Of Double, String) = Function(ByRef z As Double) z.ToString
gives the following error:Nested function does not have a signature that is compatible with delegate String)'.
While this:Private [Function] As Func(Of Double, String) = Function(ByVal z As Double) z.ToString
Does not? (The difference is ByRef/ByVal)
Furthermore, how might I implement such a thing?

I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.

I am working with TVP and I am trying to pass a data table to the stored procedure as TVP. When the command tries to ExecuteNonQuery it throws an error:Operand type clash: datetime2 is incompatible with int. The data for table-valued parameter "@tvpPermitWork" doesn't conform to the table type of the parameter.I checked the data table using the visualizer and I find all the data to be correct. I am now stuck and I don't have the time to change it to stored procedures with individual parameters.

I'm developing a filetransfer app in VB.Net..The sizes of the files vary, but can get up to 10+ GB.I already create a chat app as a test.On the clientside I run this code to connect to the server.[code]Can I also use this to transfer files?I want the app to work through a firewall and stuff.So I think I need the outgoing data on the client to go through port 80. On the server I want to be able to receive the data on another port (E.g. 8888). Is this possible?And final question is. What protocol should I use for this purpose TCP or UDP.

Can i implement PTP (precision time protocol) or NTP (simple network timing) with sockets?
If so, how can i use them to send small packages (4 to 33 bytes) with the smallest delay possible?
P.S. I would prefer to know more about PTP, I've heard that it has smaller delay.

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

Does anyone know how to create a Application Protocol? For example on a web browser you click a link that goes to "steam://appid/5654" it opens the steam application and the same happens with a bitorrent magnet link. How would you do this in VB.NET?
