vb编程怎么找mac地址

㈠ VB如何获取网卡MAC地址,请给出代码

获取mac地址，其实可以换一个思路，通过获取命令ipconfig /all 的内容，然后通过字符串匹配就可以获得了。

㈡ 用VB获取MAC地址

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

'获得MAC信息

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!//" & strComputer & "/root/cimv2")'''加上这个
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) & _
"网卡类型:" & IP.Description(I) & Chr(10) & _
"网卡地址:" & IP.macaddress(I)
Next
End If
Next
End Sub

㈢ VB6.0 怎么获得本机的IP和mac地址

gethostname 获取本机名字，gethostbyname 通过前面的名字获取主机具体信息，包括IP地址。MAC地址可以用 Netbios，以上用到的函数都是WIN32 API，具体代码请留联系方式（email或者企鹅）也可以自己网络有现成的VB代码

㈣ 用vb.net如何取得mac地址

刚刚我自己写了一段是引用System.net来做的我不喜欢用WMI主要是查出来的信息不准确，下面我附上源码希望可以加分给我

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+

"网络连接："+NetWork.Name+Environment.NewLine+

"网卡序列号："+NetWork.Id+Environment.NewLine+

"网络类型："+NetWork.NetworkInterfaceType.ToString()+Environment.NewLine+

"网络速度："+(NetWork.Speed/1000000).ToString()+"MB"+Environment.NewLine

Next

EndIf

EndSub

EndClass

㈤ 如何用VB编程,获取网关MAC

一、用nbtstat -a ip 命令,用.net中processstartinfo和process类取得命令输出，最后一行就是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获得机器的MAC地址

PrivateSubForm_Load()
GetMyIP
EndSub
SubGetMyIP()'获取IP地址、网卡类型、网卡地址
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)&_
"网卡类型:"&IP.Description(I)&Chr(10)&_
"网卡地址:"&IP.Macaddress(I)
Next
EndIf
Next
EndSub

㈦ 用vb.net如何取得mac地址

这是C#的，你可以转换一下

using System.Management;

//获取网卡的系列号
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;
}
