Compare an array column to a string?

3 posts in this topic

So the code below is mostly from a post by UEZ, but I've modified it a bit for my application.

What I'm trying to do is read all MAC address's (either connected or not) into an array and then pull the Mac address out of the DHCPv6DUID to see if there is a match.

For the code below to work, you need IPv6 enabled and for my application, (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesTCPIP6Parameters,DisabledComponents) set to 1.

In the end I will compare the two values (Mac from the DHCPv6DUID and any of the MACs in the array) if they match, do nothing, if not...do something else.

Hope this makes sense, bottomline is how do I match a string value against a column in an array. Here is my code to grab the string and the array.

#include <Array.au3>

$sHost = @ComputerName
$Dhcpv6DUID = RegRead("HKLM\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters", "Dhcpv6DUID")
$aNetworkAdapters = WMI_ListAllNetworkAdapters($sHost)

Dim $DUIDMAC = "", $xt = 1
$String = StringTrimLeft($Dhcpv6DUID, 18)
$Result = StringSplit($String, "")
For $x = 1 To $Result[0]
    If $x = $xt + 2 Then
        $xt = $x
        $DUIDMAC = $DUIDMAC & ":"
    EndIf
    $DUIDMAC = $DUIDMAC & $Result[$x]
Next

MsgBox(0,"MAC From DHCPv6DUID",$DUIDMAC)

_ArrayDisplay($aNetworkAdapters)

Func WMI_ListAllNetworkAdapters($sHost)
    Local $objWMIService = ObjGet("winmgmts:\\" & $sHost & "\root\cimv2")
    If @error Then Return SetError(1, 0, 0)
    Local $aStatus[13] = ["Disconnected", "Connecting", "Connected", "Disconnecting", "Hardware not present", "Hardware disabled", "Hardware malfunction", _
                          "Media Disconnected", "Authenticating", "Authentication Succeeded", "Authentication Failed", "Invalid Address", "Credentials Required"]
   ; $colItems = $objWMIService.ExecQuery("SELECT MACAddress, Name, NetConnectionID, NetConnectionStatus FROM Win32_NetworkAdapter", "WQL", 0x30)
   $colItems = $objWMIService.ExecQuery("SELECT MACAddress, NetConnectionStatus FROM Win32_NetworkAdapter", "WQL", 0x30)
    Local $aNetworkAdapters[1000][2], $i = 0, $iPointer
    If IsObj($colItems) Then
        For $objItem in $colItems
            With $objItem
                ;$aNetworkAdapters[$i][0] = .NetConnectionID
                ;$aNetworkAdapters[$i][1] = .Name
                $aNetworkAdapters[$i][0] = .MACAddress
                $aNetworkAdapters[$i][1] = $aStatus[.NetConnectionStatus * 1]
            EndWith
            $i += 1
        Next
        ReDim $aNetworkAdapters[$i][2]
        Return $aNetworkAdapters
    Else
        Return SetError(2, 0, 0)
    EndIf
EndFunc

Thanks for any suggestions,

Try this and see if it gives you what you're looking for.

#include <Array.au3>
#include <Constants.au3>
$sHost = @ComputerName
$Dhcpv6DUID = RegRead("HKLM\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters", "Dhcpv6DUID")
$aNetworkAdapters = WMI_ListAllNetworkAdapters($sHost)

Global $DUIDMAC = "", $xt = 1
$String = StringTrimLeft($Dhcpv6DUID, 18)
$Result = StringSplit($String, "")
For $x = 1 To $Result[0]
    If $x = $xt + 2 Then
        $xt = $x
        $DUIDMAC = $DUIDMAC & ":"
    EndIf
    $DUIDMAC = $DUIDMAC & $Result[$x]
Next
For $Count = 1 to Ubound($aNetworkAdapters) - 1
    If $aNetworkAdapters[$Count][0] = $DUIDMAC Then
        MsgBox($mb_systemmodal, "Found it", "Found the MAC address in the array at: " & $Count)
        ExitLoop
    EndIf
Next

MsgBox(0, "MAC From DHCPv6DUID", $DUIDMAC)
