如何獲取網卡地址(MAC地址)：

VC++編寫的代碼，適用于windows環境，API實現

/*char *pMACAdr,返回網卡地址的buff,

?int *nBuffLen前一個參數的長度,

?int nAdapterID = 0網卡號,針對多網卡問題,有的機器不止一個網卡,默認為0

*/

#include <NB30.H>
#pragma comment(lib, "C:\\Program Files\\Microsoft Visual Studio\\VC98\\Lib\\Netapi32.lib")//自己找安裝目錄

BOOL GetMACAdress(char *pMACAdr, int *nBuffLen, int nAdapterID = 0)
{
?if (NULL == pMACAdr || *nBuffLen <= 0 || nAdapterID < 0) {
??*nBuffLen = 0;
??return FALSE;
?}
?memset(pMACAdr, 0, *nBuffLen);

?typedef struct _ASTAT_???

如果想現存的DLL或者ActiveX控制, 在我的資源里有封裝好的DLL與ActiveX控制下載, 直接調用接口使用即可
