vbmac:如何用VB获得机器的MAC地址-vb教程



sp; 我有个asp做网站WebSite现在想通过asp嵌入网页内(Control控件)读取客户端网卡mac地址请各位前辈多多帮忙

下面这代码可以做成Control控件形式?嵌入网页后通过asp读取客户端网卡mac地址请各位前辈多多帮忙告诉如何做我是个初学者有急用谢谢!!!

Form Code

To a form add a command button (Command1), and a text box (Text1). Labels and
frames are optional. Add the following to the command button:

------------------------------------------------------------------------------
--


Option Explicit

Private Sub Command1_Click

Text1 = GetMACAddress

End Sub
´--end block--´


Comments

Other hardware and software may be assigned their own MAC addresses. For
example, a modem can have a MAC address. Also, a RAS client or server can
\"dummy\" network adapters that correspond to a dialup or serial
connection. Normally, these MAC addresses are randomly generated. If an
adapter status is called _disibledevent=>


LANA.
Connect using any LANA:
For servers, submit an NCBLISTEN on each LANA. If necessary, cancel any
outstanding listen after the first listen is satisfied.
For clients, submit an NCBFINDNAME (Windows NT only) or an NCBCALL (either
Windows NT or Windows 95) on each LANA. The first successful find name or
call will indicate which LANA to use. When using NCBCALL instead of
NCBFINDNAME, you must cancel any pending NCBCALLs and hang up the extra
completed calls (when two or more calls are successful.)
It is a good idea to submit NCBADDNAME, NCBLISTEN, NCBFINDNAME, and NCBCALL
asynchronously. Asynchronous requests will be processed almost in parallel on
each transport.

This architecture is quite beneficial. Once your application is written to
establish connections in this manner, it will support any transport that
NetBIOS can use. As a result, your customers will not have to configure
anything within your application, and your application will not be affected
by dynamic LANAs such as dial-up adapters or plug-and-play hardware.
