   int Privilege = 1;
   bool Enabled = true;


   bool result = objZkeeper.SetUserInfo(MachineNumber, dwEnrollNumbre, Name, Password, Privilege, Enabled);

int iMachineNumber = Convert.ToInt32(txtMachineNumber.Text);
int idwErrorCode = 0;
bool bEnabled = true;
string sdwEnrollNumber = employee.EmployeeID_PK.ToString();
string sName = EmpName.Text;
string sPassword = txtPassUser.Text;
int iPrivilege = 0;
string sCardnumber = "0";
objZkeeper.EnableDevice(iMachineNumber, false);
objZkeeper.SetStrCardNumber(sCardnumber);
if (objZkeeper.SSR_SetUserInfo(iMachineNumber, sdwEnrollNumber, sName, sPassword, iPrivilege, bEnabled))//upload the user's information(card number included)
{
    MessageBox.Show("Add succesful");
}
else
{
    objZkeeper.GetLastError(ref idwErrorCode);
    MessageBox.Show("Operation failed,ErrorCode=" + idwErrorCode.ToString(), "Error");
}
objZkeeper.RefreshData(iMachineNumber);
objZkeeper.EnableDevice(iMachineNumber, true);
