View 2 Repliesfinding my public IP address using .NET?
I've seen code that simply gets the text output from whatismyip.com but I want to use my own domain to find the IP address because I know it will always be available and I can use it as much as I like.
I'm assuming that I could get my public IP somehow by pinging a remote server such as a domain name that I own, but I'm struggling to find anything other than the built in ping in VB.NET which simply gives true or false as a result.
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

View 1 RepliesI used to develop applications in VBA, but now I'm using SQL Server 2008 Integration Services for a lot of the functionality, and using VB.NET as the scripting language where needed - all of which are new to me. I need to do the same string manipulation in several different SSIS tasks. With VBA, I'd simply write a function and declare it Public, and I could use it from any module. E.g.
Public Function MakeId(ByVal Country As String, ByVal Postcode As String) As String
....
End Function
' later...
Dim MyId as String
MyId = MakeId(County, Postcode)
But when I do that in a Script Task or Script Component, I find I can't call the function from VB in any other Script Task or Component; it says MakeId is undeclared. It works within its own 'box', but not from anywhere else.

I have a public readonly variable in a module, but when I try to set it in my form load event for the first time I get 'ReadOnly' variable cannot be the target of an assignment. It is my understanding that a ReadOnly variable can only be set once and after that you would get an error when setting it.

I have this code that gets the local IP, It works when I'm directly connected to my ISP modem but when I'm in a router it displays the mac instead of the IP. I don't know what's missing in the code.
code
Imports System.Net
Private Sub GetIPAddress()
Dim ip As IPHostEntry = Dns.GetHostEntry(Dns.GetHostName)
Label25.Text = ip.AddressList.GetValue(0).ToString
End Sub
e.g. mine

I have these list of RS-232 strings declared in my public class
Public Class TouchInterface
Dim WatchTVbtnCmd As String = "rs232command1"
Dim VolUpbtnCmd As String = "rs232command2"
Dim VolDownbtnCmd As String = "rs232command3"
Dim SystemOffbtnCmd As String = "rs232command4"
Dim RadiobtnCmd As String = "rs232command5"
Dim MusicbtnCmd As String = "rs232command6"
I then have this private sub. For the sake of this thread, what I would like to do is get the name of the label that was clicked which in the code below is already done, convert it to string (not sure if this needs to be done), this is also done in the code below. Next I want to compare the labelnamestring to all the variables in the public class to find out which one it is equal to and then disply that variable which should be my rs232 string in the message box. I have also added "Cmd" to the variable names above so I also need to work out how to add the text "Cmd" to the string to properly compare.
Private Sub Musicbtn_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WatchTvbtn.Click, VolUpbtn.Click, VolDownbtn.Click, SystemOffbtn.Click, Radiobtn.Click, Musicbtn.Click, GardenVolUpbtn.Click, GardenVolDownbtn.Click, GardenRadiobtn.Click, GardenOffbtn.Click, GardenMusicbtn.Click, GardenMediaCenterbtn.Click
Dim labelname As Label = DirectCast(sender, Label)

Basicly I have a set of public subs, (not related to a form), inside a public class, and all of them share a variable. One of the subs, the one called for first gives the variable a value.
When the next sub is called, the variable is null. The data in the variable has been erased as the execution of the prior public sub ended I'm guessing.
