Question

要求VC串口每接收一次数据，显示在不同的编辑框中，但结果都显示在一个中，请教如何解决？flag应该放在哪？

static unsigned int flag;
flag=0;
CString m_edit;
m_edit.Format(("%d"),myData);
int data=atoi(m_edit);
if(flag==0&&data!=11)
{
m_edit1.Format(("%d"),myData);
switch(data)
{
case1:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case2:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case3:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case4:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case5:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case6:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case7:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case8:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case9:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
case10:
{
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
break;
}
}
}
elseif(data==11)
{
flag=1;
}

if(flag==1&&data!=11)
{
m_edit2.Format(("%d"),myData);
switch(data)
{
case1:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case2:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case3:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case4:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case5:
{

GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case6:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case7:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case8:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
case9:
{
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
break;
}
}
}
elseif(data==11)
{
flag=2;

}

把你的代码直接改成如下看看……
static unsigned int flag;
flag=0;
CString m_edit;
m_edit.Format(("%d"),myData);
int data=atoi(m_edit);
if(flag==0 && data!=11){
m_edit1.Format(("%d"),myData);
GetDlgItem(IDC_EDITR1)->SetWindowText(m_edit1);
}
else if(data==11) flag=1;

if(flag==1 && data!=11){
m_edit2.Format(("%d"),myData);
GetDlgItem(IDC_EDITR2)->SetWindowText(m_edit2);
}
else if(data==11) flag=2;

不明白为啥非要用switch语句
