[RESOLVED] Changing IP address with VB

Hey all,

I have a PC, and I want to be able to change the IP address easier than going to Network connections > Picking the connection > Properties > Changing IP every time. The IP address is static (It's a laptop that I'm using for configuring multiple Routers for my CCNA labs, I want to be able to change the IP address more efficiently!).

Attatched is a "Front only" view of what I'm trying to do. The program will sit on the bottom corner of the screen and will let me change the IP just by intering it and hitting a button, or clicking a "Preset settings" button.

The question is - is there code that I can put in VB that will actually change the IP address settings for that particular network adaptor? I'm running XP.

Thanks for any advice!

Have a look at this.

and .. using the example zynder posted ..
i created a modified version of that ...
returns True or False. You could modify that, its just an example.

You have to manually enter the adaptor name though.
I didnt yet find code to enumerate through them, for XP that is.

FORM:
if entering DNS, enter multiple DNS servers with a comma (no spaces) between them

VB Code:

Thank you for all your replies!

I've been looking through the code, but I'm a bit of a VB noob I'm afraid and all the references to Reg keys and whatnot are losing me a bit.

I don't need to edit the DNS settings, nor do I need to be able to change between static and dynamic IP.
If it's not too much trouble, would someone be able to take one of these examples and strip out all the stuff about changing DNS settings and all the other bits? I just need something that calls the code, to go into my Command1, such as the example above, and a chunk of code that just changes the IP address, subnet mask, and default gateway.

Thank you!

Hi, both examples i posted change only the IP, Subnet, and Gateway.
DNS is just an optional item in both of them.

If you arent going to know the Adapter name, which I doubt you will if you are giving this to other people, then use the WMI one (1st one), for now at least. All you need is the one line inside the Command1_Click sub.

SetStaticIp "192.168.0.2", "255.255.255.0", "192.168.0.1"

The other 2 subs can go either in the same form or in a seperate module, doesnt matter. You can get the return string from the function by assigning it to a string variable, such as in the example. Or just set it like above.
If you look at the attachment in the WMI post, you will also see there is more code for getting the IP information etc.

However, typically you must also set the DNS info when using a Static IP or you wont get online.

I don't mind setting the adaptor myself, the program is only for me at the moment anyway. What buttons/textboxes/etc are required for your second one though? Like I said, I'm new at this and the code all just turns into a blur to me when I read it, I only know very simple commands :(. I'm just trying to figure out which bits I can strip out relating to DNS settings and whatnot, but it's quite confusing for me.

if you dont care about getting a return string from it ...
and without the DNS info also ..

VB Code:

Private Sub Command1_Click()
    SetIP "192.168.0.2", "255.255.255.0", "192.168.0.1"
End Sub
 
Public Sub SetIP(ByVal pIPAddress As String, ByVal pSubnet As String, _
                         ByVal pGateway As String)
                            
    Dim objWMIService       As Object
    Dim colNetAdapters      As Object
    Dim objNetAdapter       As Object
    Dim strSelect           As String
    Dim strIPAddress        As String
    Dim strSubnet           As String
    Dim strGateway          As String
    Dim varIPAddress        As Variant
    Dim varSubnet           As Variant
    Dim varGateway          As Variant
    Dim varGatewaymetric    As Variant
    
    On Error GoTo Error_Handler
 
    Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
    strSelect = "Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE"
    Set colNetAdapters = objWMIService.ExecQuery(strSelect)
    
    strIPAddress = Trim$(pIPAddress)
    strSubnet = Trim$(pSubnet)
    strGateway = Trim$(pGateway)
    
    varIPAddress = Array("" & strIPAddress & "")
    varSubnet = Array("" & strSubnet & "")
    varGateway = Array("" & strGateway & "")
    varGatewaymetric = Array(1)
    
    For Each objNetAdapter In colNetAdapters
        objNetAdapter.EnableStatic varIPAddress, varSubnet
        objNetAdapter.SetGateways varGateway, varGatewaymetric
    Next
    
Error_Handler:
    Set colNetAdapters = Nothing
    Set objWMIService = Nothing
    Set objNetAdapter = Nothing
End Sub

Oh thank you! That looks nice and simple :D.

What is a return string? Does it need to return anything? It's setting data, not getting data. Like I said I'm only a noob at this. I don't know, do I want a return string? All I know is that I don't need to set DNS server settings, or change between static and dynamic IP :).

Thanks again ^^.

or just use the app i attached and add / delete / modify the buttons ..
all they do is call the procedures in the code .. you can alter them or create additional procedures with the preset info.

incase it doesnt change the info or there is an error while doing so, like if the user enters an incorrect IP, Subnet, or Gateway .. but you need to know what the error returned means hence that extra "NetworkResults" function in the first one. So basically incase you want the user to be alerted that there was an error and what that error is, or if it completed successfully.

How does it return it, as a msgbox?

And if it would be possible, may I have the code with with the return code but without the DNS stuff? I believe it gets rid of a lot of the reg stuff then. I don't want to just put all the code in and delete buttons because

A) It creates unnessecery code-bloat
B) I wouldn't know which buttons should be "Set" of "Un-set" by default, and if, say, radio boxes go, and the program has to perform an IF check to see which box is ticked, won't it crash?
C) It makes it hard for me to try and edit the code afterwards because I don't know what's going on, and
D) I don't know what buttons/radio boxes / textboxes and etc to add to the form or what to call them!

Thanks!

it returns it as a string in the above example, then you can do what you like with the string. The actual return is a number, that function just converts it to english.

If you only want to know True or False then I can post that code, without the DNS.

without DNS, returns a string.

Wow that's great, thanks a lot! I'll have a look through it all and see what I can do.

Thanks again!

Oh, one last quick question - is there a bit of code for reading the IP - i.e, so I can have a button to "load current settings", or a text label to show the current settings? Thanks!

no prob .. also you can reference WMI in the project using Microsoft WMI scripting Library, or just set them as object as in the above examples ..

here is how to get the info, in this example i put the return values in the function as byref but you could just assign them to your text boxes direct.
It returns false if there is an error, true if no error.
I put textbox and WMI reference options in comments

VB Code:

Private Sub Command1_Click()
    Dim sIP As String, sMask As String, sGate As String
    If GetIPInfo(sIP, sMask, sGate) = True Then
        Debug.Print sIP         '// txtIP.Text = sIP
        Debug.Print sMask       '// txtSubnet.Text = sMask
        Debug.Print sGate       '// txtGateway.Text = sGate
    Else
        Debug.Print "Error!"    '// MsgBox "Error!"
    End If
End Sub
 
'// wmi get ip info
Public Function GetIPInfo(ByRef strIPAddress As String, _
    ByRef strSubnet As String, ByRef strGateway As String) As Boolean
    Dim WMIService  As Object   '// As SWbemServices
    Dim IPConfigSet As Object   '// As SWbemObjectSet
    Dim IPConfig    As Object   '// As SWbemObject
    Dim SQL As String, i As Long
On Error GoTo Error_Handler
    '// connect and query
    Set WMIService = GetObject("winmgmts:\\.\root\cimv2")
    SQL = "Select IPAddress, IPSubnet, DNSServerSearchOrder, DefaultIPGateway, " & _
          "DHCPEnabled from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE"
    Set IPConfigSet = WMIService.ExecQuery(SQL)
    '// loop through info
    For Each IPConfig In IPConfigSet
        '// get ip address
        If Not IsNull(IPConfig.IpAddress) Then
            For i = LBound(IPConfig.IpAddress) To UBound(IPConfig.IpAddress)
                strIPAddress = IPConfig.IpAddress(i)
                '// txtIP.Text = sIP
            Next i
        End If
        '// get subnet mask
        If Not IsNull(IPConfig.IPSubnet) Then
            For i = LBound(IPConfig.IPSubnet) To UBound(IPConfig.IPSubnet)
                strSubnet = IPConfig.IPSubnet(i)
                '// txtSubnet.Text = sMask
            Next i
        End If
        '// get gateway
        If Not IsNull(IPConfig.DefaultIPGateway) Then
            For i = LBound(IPConfig.DefaultIPGateway) To UBound(IPConfig.DefaultIPGateway)
                strGateway = IPConfig.DefaultIPGateway(i)
                '// txtGateway.Text = sGate
            Next i
        End If
    Next IPConfig
Error_Handler: '// cleanup
    Set IPConfigSet = Nothing
    Set WMIService = Nothing
    GetIPInfo = Err.Number = 0
End Function

Ooh thank you!
Thanks for all the help!

no, only in the post where it uses the registry, the second post i made.
all this other code is WMI stuff and doesnt use the registry.
The PC needs to have WMI installed, with XP should be no issues.

Thank you so much again for helping me :)

I doubt this will be of any use to anyone, I'm sure everyone here could make something much better and more easily, but I'd like to share the app anyway in case anyone can find it useful. Feel free to nick bits of the code (hell, most of the code in there for changing the IP was from rory :D), or re-create it as you see fit ^^.

VB Code:

Dim sAdapter As String
Dim objWMIService As Object
Dim colNetAdapters As Object
Dim objNetAdapter As Object
 
  Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
  sAdapter = "Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE"
  Set colNetAdapters = objWMIService.ExecQuery(sAdapter)
  ' loop through adaptor info
  For Each objNetAdapter In colNetAdapters
    cmbAdapter.AddItem objNetAdapter.Caption
  Next objNetAdapter
  If cmbAdapter.ListCount > 0 Then
    cmbAdapter.ListIndex = 0
  Else
    MsgBox "There doesn't appear to be any IP-enabled Network Adapter in this computer.", vbCritical, App.EXEName
  End If
 
'When selecting the adapter to set the IP on, just cycle through colNetAdapters, looking for the objNetAdapter.Caption that matches cmbAdapter.Text

How about a snippet to set the adapter to dynamic? I can't seem to find that info.

I was meaning using the registry or API :-)

What do you mean by Dynamic in this case?
If DHCP then here it is ..

VB Code:

Private Sub Command1_Click()
    If SetDHCP = True Then
        Debug.Print "DHCP Set Successfully"
    End If
End Sub
 
'// wmi set dhcp
Public Function SetDHCP() As Boolean
    Dim objWMIService As Object
    Dim colNetAdapters As Object
    Dim objNetAdapter As Object
    Dim strSelect As String
    Dim lngEnable As Long
    Dim lngDns As Long
On Error GoTo Error_Handler
    '// connect and query
    Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
    strSelect = "Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE"
    Set colNetAdapters = objWMIService.ExecQuery(strSelect)
    '// loop through adaptor info
    For Each objNetAdapter In colNetAdapters
        lngEnable = objNetAdapter.EnableDHCP()
        lngDns = objNetAdapter.SetDNSServerSearchOrder()
    Next
    If lngEnable = 0 And lngDns = 0 Then SetDHCP = True
Error_Handler: '// cleanup
    Set colNetAdapters = Nothing
    Set objWMIService = Nothing
    Set objNetAdapter = Nothing
End Function

That's what I was looking for. Thanks. I haven't been able to find any extensive documentation on WMI.

You can download and install this from Microsoft, though it requires IE.
http://www.microsoft.com/downloads/d...displaylang=en

Lately ive just been using MSDN as it has most of that info there and its easier to copy past the properties and methods.
http://msdn2.microsoft.com/en-us/library/aa389273.aspx

If i cant find something there then i go back to the WMI tools for further info.

Also, if there is anything in particular you cant find you can always search for "VBScript WMI" in google .. or browse the "Scripting Guys" section here:
