Weird Problem

Hi all,

Code:

---

#include "stdafx.h"
#include "Asimulator.h"
#include "inputBoxAP.h"
#include <cstring>
#include <fstream>

// inputBoxAP dialog

IMPLEMENT_DYNAMIC(inputBoxAP, CDialog)

inputBoxAP::inputBoxAP(CWnd* pParent /*=NULL*/)
        : CDialog(inputBoxAP::IDD, pParent)
        , amtAP(0)
{
       
}

inputBoxAP::~inputBoxAP()
{
}

void inputBoxAP::DoDataExchange(CDataExchange* pDX)
{
        CDialog::DoDataExchange(pDX);
        DDX_Text(pDX, IDC_EDIT1, amtAP);
        DDV_MinMaxInt(pDX, amtAP, 3, 5);
}


BEGIN_MESSAGE_MAP(inputBoxAP, CDialog)
        ON_EN_CHANGE(IDC_EDIT1, &inputBoxAP::OnEnChangeEdit1)
        ON_EN_UPDATE(IDC_EDIT1, &inputBoxAP::OnEnUpdateEdit1)
        ON_BN_CLICKED(IDOK, &inputBoxAP::OnBnClickedOk)
END_MESSAGE_MAP()


// inputBoxAP message handlers -- The most imprt handler is OnBnClickedOK(), the rest don't care

void inputBoxAP::OnEnChangeEdit1()
{
        // TODO:  If this is a RICHEDIT control, the control will not
        // send this notification unless you override the CDialog::OnInitDialog()
        // function and call CRichEditCtrl().SetEventMask()
        // with the ENM_CHANGE flag ORed into the mask.

        // TODO:  Add your control notification handler code here
       
}

void inputBoxAP::OnEnUpdateEdit1()
{
        // TODO:  If this is a RICHEDIT control, the control will not
        // send this notification unless you override the CDialog::OnInitDialog()
        // function to send the EM_SETEVENTMASK message to the control
        // with the ENM_UPDATE flag ORed into the lParam mask.

        // TODO:  Add your control notification handler code here
}

void inputBoxAP::OnBnClickedOk()
{
        // TODO: Add your control notification handler code here
        OnOK();
       
        ofstream inputdata; < -- ERROR HERE

        // To test if the operation is functioning correctly
        CString temp;       
        temp.Format(_T("%d"),amtAP);
        AfxMessageBox(temp);
}

Notice that at the last function, i include ofstream inputdata, but there is always an error produced:

ofstream undeclare identifier.

What is wrong here?

ofstream is inside of namespace std. Use it like this

Code:

---

std::ofstream f;
