我的任务
分享怎么把串口数据接收到的数据显示到编辑框里
// TODO: 在此处添加消息处理程序代码
if (m_mscom.get_CommEvent() == 2)
{
char str[1024] = { 0 };
long k;
VARIANT InputData = m_mscom.get_Input(); //读缓冲区
COleSafeArray fs;
fs = InputData; //VARIANT型变À量转换为COleSafeArray型变量
for (k = 0; k<fs.GetOneDimSize(); k++)
fs.GetElement(&k, str + k); //转换为BYTE型数组
m_EditReceive += str; // 接收到编辑框里面
//SetTimer(1,10,NULL); //延时10ms
UpdateData(false);
这个是我原来的代码，怎么修改是接收到的数据一个个显示到我的编辑框里。

目前你的代码这样做是累加数据
m_EditReceive += str; // 接收到编辑框里面
改成下面这样就是单次数据
m_EditReceive = str;

你没懂我的意思，我意思是先在串口接收了数据，上面那段代码是我串口数据代码。然后我要把那些数据显示到一个个显示到我另外添加的编辑框里，怎么添加代码啊？？？
