Button IDC_CALCULATE C&alculate

Static Text GCD:

Edit Control IDC_GCD

Button IDCANCEL &Close

29. Add a Value variable for the IDC_NUMBER1 control and name it m_Number1


30. Add a Value variable for the IDC_NUMBER2 control and name it m_Number2


31. Add a Value variable for the IDC_GCD control and name it m_GCD


32. To add the library to the current project, on the main menu, click Project -> Add
    Existing Item... and select BusMath.lib


33. On the dialog box, double-click the Calculate button and implement it OnClick event
    as follows:

// BusMathTest2Dlg.cpp : implementation file

//

#include "stdafx.h"

#include "BusMathTest2.h"

#include "BusMathTest2Dlg.h"

#include ".\busmathtest2dlg.h"

#include "bmcalc.h"

#ifdef _DEBUG

#define new DEBUG_NEW

#endif

// CBusMathTest2Dlg dialog

CBusMathTest2Dlg::CBusMathTest2Dlg(CWnd* pParent /*=NULL*/)

: CDialog(CBusMathTest2Dlg::IDD, pParent)

, m_Number1(_T("0"))

, m_Number2(_T("0"))

, m_GCD(_T("0"))

{

m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

}

...

void CBusMathTest2Dlg::OnBnClickedCalculate()

{

// TODO: Add your control notification handler code here

int Nbr1, Nbr2, Result;

UpdateData(TRUE);

Nbr1 = atoi(m_Number1);

Nbr2 = atoi(m_Number2);

Result = GreatestCommonDivisor(Nbr1, Nbr2);

m_GCD.Format("%d", Result);

UpdateData(FALSE);

}

34. Test the application. Here is an example:
