My suggestion would be to nix the calls to UpdateData(). Then create three CEdit member variables, one for each edit control. Now in the OnMultiply() method:

void CPractica6Dlg::OnMultiply() 
{
    CString strA,
            strB,
            strC;
 
    m_editA.GetWindowText(strA);
    m_editB.GetWindowText(strB);
    strC.Format("%d", atoi(strA) * atoi(strB));
    m_editC.SetWindowText(strC);
}

Will it work?
void CPractica6Dlg::OnMultiply()
{

UpdateData(TRUE);
m_result=m_numA*m_numB;
UpdateData(FALSE);
}

I dont know what you mean?
Sorry i'm a little bit new with visual c++.
is this what are you talking about?

CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CPractica6Dlg)
DDX_Text(pDX, IDC_NUMA, m_numA);
DDX_Text(pDX, IDC_NUMB, m_numB);
DDX_Text(pDX, IDC_RESUL, m_result);
//}}AFX_DATA_MAP

Situation out of control. Cease Fire!. But check the values of m_numA, m_numB & m_result by displaying in a message box jsut before the multiplication and just after the multiplication.

Values
m_a=1
m_b=2
pick radiobuton +
pick solution
m_result=3
then I change values
m_a=3
m_b=4
radiobuton + activated
pick solution
m_result=3 and m_a and m_b changed to
m_a=1
m_b=2
but if i do this it works
m_a=3
m_b=4
radiobuton + activated but i pick it another time
pick solution
m_result=7

This is the problem with UpdateData(). If not used 100% correctly, it causes more problems than it solves.

I discover that if i push twice in the radio button it works. i thinks that is because when you change the radio button it dont reload the new values so if you pick twice in the same radio button satrt to work.
Any ideas to solve this???
