evc的字节问题

Question

怎么改了一下程序界面，EVC从串口取的数从一个字节变成了两个字节？
原来是  24 84
现在是  24 0  96 51
84变成96 51是怎么回事？
下面是程序代码！！

Answer 1

if(length!=0)
{
if(HexDisplay)
{
for(i=0;i<length;i++)
{
if(data[i]<16)
{
THex.Format(_T("0%d "),data[i]);
}
else
{
THex.Format(_T("%2d "),data[i]);
}
m_strDataReceived+=THex;
FILE* fp;   
             fp=fopen("datai.txt","a");
fprintf(fp,"%d-------\n",THex);
                fclose(fp);


}
}
else
{
m_strDataReceived=CString(data).Left(length);
}

m_strReceive+=m_strDataReceived;
m_strDataReceived=_T("");
SetDlgItemText(IDC_RECEIVE,m_strReceive);
m_CtrlReceive.SetSel(m_strReceive.GetLength(),m_strReceive.GetLength(),FALSE);
}
