1、編譯沒有錯誤。
--------------------Configuration: EastR - Win32 Debug--------------------
EastR.exe - 0 error(s), 0 warning(s)
2、運行到某一個函數報錯
3、調試到int m_ClockNo = atoi(NewNo->GetItemText(0,0).GetBuffer(NewNo->GetItemText(0,0).GetLength()));
報Unhandled exception in EastR.exe (MFC42D.DLL) :0xC0000005;Access Violation錯誤
附錯誤函數代碼：
void CChangeClockNo::OnOK()
{
// TODO: Add extra validation here
UpdateData(true);
int New_id = atoi(m_strNewID.GetBuffer(m_strNewID.GetLength ()));
int m_ClockNo = atoi(NewNo->GetItemText(0,0).GetBuffer(NewNo->GetItemText(0,0).GetLength()));
int m_Rate = atoi(NewNo->GetItemText(0,2).GetBuffer(NewNo->GetItemText(0,2).GetLength ()));
int Com = 1;
int nItem = 0;
HANDLE hPort;
hPort = OpenCommPort(Com,m_Rate);
if(!hPort)
{
AfxMessageBox("端口被占用！");
}
else
{

GetClockModel(hPort,Model,Ver,cls);
if(Ver==880 || Ver==889 || Ver==900)
