获取机器码 及 检测注册码是否有效

 

 

CString cstrMac; GetDlgItemText(IDC_EDIT1, cstrMac); cstrMac.TrimLeft(); cstrMac.TrimRight(); if(cstrMac.GetLength() == 0) { return; } //获取Key int nKey = 1; int i = 0; for(i = 0; i < cstrMac.GetLength(); i++) { nKey += (cstrMac.GetAt(i)^0xa9)*(i+1)*256; } char key[255]; sprintf(key, "%x", nKey);// this->SetDlgItemText(IDC_EDIT2, key);

根据机器码计算注册码(注册机)
