vb編程怎麼找mac地址

㈠ VB如何獲取網卡MAC地址,請給出代碼

獲取mac地址，其實可以換一個思路，通過獲取命令ipconfig /all 的內容，然後通過字元串匹配就可以獲得了。

㈡ 用VB獲取MAC地址

Private Sub Form_Load()
Dim Mac
strComputer = "."
Mac = ""

'獲得MAC信息

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!//" & strComputer & "/root/cimv2")'''加上這個
Set colItems = objWMIService.ExecQuery("Select * from Win32_NetworkAdapterConfiguration Where IPEnabled=TRUE")
For Each objItem In colItems
Mac = Mac + " " + objItem.macaddress
Next
TeMac.Text = Replace(Trim(Mac), ":", "-")

strComputer = "."
Set objWMI = GetObject("winmgmts://" & strComputer & "/root/cimv2")
Set colIP = objWMI.ExecQuery("Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE")

For Each Ip In colIP
If Not IsNull(Ip.ipaddress) Then
For i = LBound(Ip.ipaddress) To UBound(Ip.ipaddress)
'Mac = Ip.macaddress(I)objObject.DNSHostName
If Ip.ipaddress(i) = "0.0.0.0" Then
Else

TeIp.Text = Trim(TeIp.Text + " " + Ip.ipaddress(i))
End If
'MsgBox "IP 地址:" & IP.ipaddress(I) & Chr(10) & _
"網卡類型:" & IP.Description(I) & Chr(10) & _
"網卡地址:" & IP.macaddress(I)
Next
End If
Next
End Sub

㈢ VB6.0 怎麼獲得本機的IP和mac地址

gethostname 獲取本機名字，gethostbyname 通過前面的名字獲取主機具體信息，包括IP地址。MAC地址可以用 Netbios，以上用到的函數都是WIN32 API，具體代碼請留聯系方式（email或者企鵝）也可以自己網路有現成的VB代碼

㈣ 用vb.net如何取得mac地址

剛剛我自己寫了一段是引用System.net來做的我不喜歡用WMI主要是查出來的信息不準確，下面我附上源碼希望可以加分給我

ImportsSystem.Net

ImportsSystem.Net.NetworkInformation

PublicClassForm1

PrivateSubbtnGetMac_Click(ByValsenderAsSystem.Object,ByValeAsSystem.EventArgs)HandlesbtnGetMac.Click

DimNetworkInterfaces()AsNetworkInterface

NetworkInterfaces=NetworkInterface.GetAllNetworkInterfaces()

IfNetworkInterfaces.Length>0Then

txtMac.Text=txtMac.Text+

"MAC地址："+NetWork.GetPhysicalAddress().ToString()+Environment.NewLine+

"網路連接："+NetWork.Name+Environment.NewLine+

"網卡序列號："+NetWork.Id+Environment.NewLine+

"網路類型："+NetWork.NetworkInterfaceType.ToString()+Environment.NewLine+

"網路速度："+(NetWork.Speed/1000000).ToString()+"MB"+Environment.NewLine

Next

EndIf

EndSub

EndClass

㈤ 如何用VB編程,獲取網關MAC

一、用nbtstat -a ip 命令,用.net中processstartinfo和process類取得命令輸出，最後一行就是mac地址 mac address.
二、用.net中的wmi：system.management namespace hosted in system.management.dll assembly
例：
managementobjectsearcher query = new managementobjectsearcher(

㈥ 如何用VB獲得機器的MAC地址

PrivateSubForm_Load()
GetMyIP
EndSub
SubGetMyIP()'獲取IP地址、網卡類型、網卡地址
DimstrComputerAsString
DimobjWMIAsObject
DimcolIPAsObject
DimIPAsObject
DimIAsInteger
strComputer="."
SetobjWMI=GetObject("winmgmts://"&strComputer&"/root/cimv2")
SetcolIP=objWMI.ExecQuery_
("Select*fromWin32_=TRUE")
ForEachIPIncolIP
IfNotIsNull(IP.IPAddress)Then
ForI=LBound(IP.IPAddress)ToUBound(IP.IPAddress)
MsgBox"IP地址:"&IP.IPAddress(I)&Chr(10)&_
"網卡類型:"&IP.Description(I)&Chr(10)&_
"網卡地址:"&IP.Macaddress(I)
Next
EndIf
Next
EndSub

㈦ 用vb.net如何取得mac地址

這是C#的，你可以轉換一下

using System.Management;

//獲取網卡的系列號
private static string GetMacAddress()
{
string ret = "";
try
{
ManagementClass cimobject = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = cimobject.GetInstances();
if (moc.Count == 0)
return "";
else
{
foreach (ManagementObject mo in moc)
{
if ((bool)mo["IPEnabled"] == true)
{
ret = (string)mo.Properties["MacAddress"].Value;
break;
}
}
}
}
catch
{
ret = "";
}
return ret;
}
