如何獲取網(wǎng)卡地址(MAC地址)：

VC++編寫(xiě)的代碼，適用于windows環(huán)境，API實(shí)現(xiàn)

/*char *pMACAdr,返回網(wǎng)卡地址的buff,

?int *nBuffLen前一個(gè)參數(shù)的長(zhǎng)度,

?int nAdapterID = 0網(wǎng)卡號(hào),針對(duì)多網(wǎng)卡問(wèn)題,有的機(jī)器不止一個(gè)網(wǎng)卡,默認(rèn)為0

如果想現(xiàn)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(diào)用接口使用即可
