[功能描述]ipX和NETBIOS接口需要网络地址。该文通过详细的步骤演示了如何通过VB获取网卡地址。
步骤:
1)在VisualBasic生成标准的EXE文件。缺省创建Form1。
2)在Form1中添加一命令按钮,缺省名为Command1。
3)把下列代码放到Form1中说明部分。

把下面的代码放入Command1_Click的事件中:
PrivateSubCommand1_Click()

myNcb.ncb_command=NCBRESET
bRet=Netbios(myNcb)
myNcb.ncb_command=NCBASTAT

myNcb.ncb_callname="* "
DimmyASTATAsASTAT,tempASTATAsASTAT
DimpASTATAsLong
myNcb.ncb_length=Len(myASTAT)
Debug.PrintErr.LastDllError
pASTAT=HeapAlloc(GetProcessHeap(),HEAP_GENERATE_EXCEPTIONSOrHEAP_ZERO_MEMORY,myNcb.ncb_length)
IfpASTAT=0Then
Debug.Print"memoryallcoationfailed!"
ExitSub
EndIf
myNcb.ncb_buffer=pASTAT
bRet=Netbios(myNcb)
Debug.PrintErr.LastDllError
CopyMemorymyASTAT,myNcb.ncb_buffer,Len(myASTAT)
MsgBoxHex(myASTAT.adapt.adapter_address(0))&""&Hex(myASTAT.adapt.adapter_address(1))_

&""&Hex(myASTAT.adapt.adapter_address(4))&""_
&Hex(myASTAT.adapt.adapter_address(5))
HeapFreeGetProcessHeap(),0,pASTAT
EndSub
4)按F5,运行该程序。
5)点击Command1。注意,网卡地址将在一信息框中显示出来。->
