Clearing entries in edit boxes?

[OOP]

Hello, i've encountered a problem with how to clear the entries in two edit boxes when a push button is clicked. I've tried the Clear() function but fails. Your feedback/help would be appreciated. Thanks.

Depending how you are using the edit controls e.g.
1. The controls are associated with tow CEdit objects:
CEdit m_edText2;
CEdit m_edText1;
then on your handler
void CMyView::OnButtonClear1()
{
m_edText1.SetWindowText(""
m_edText2.SetWindowText(""

}
Note that the DoDataExchage () should contains:
DDX_Control(pDX, IDC_EDIT1, m_edText1);
DDX_Control(pDX, IDC_EDIT2, m_edText2);

2. The edit box controls are associated with tow CString variables:
CString m_sLastName;
CString m_sFirstName;
Then the handler of the button when you want to reset should be :

void CEx10View::OnButtonClear2()
{
m_sLastName.Empty();
m_sFirstName.Empty();
UpdateData(false);

}
and the DoDataExchange() should include :

DDX_Text(pDX, IDC_EDIT1, m_sLastName);
DDX_Text(pDX, IDC_EDIT2, m_sFirstName);

Thanks obislavu,

I've managed to clear the edit box by using the following codes;

box = "";
UpdateData(FALSE);

*where box is a variable which i add to the edit box with the properties you've listed.

i didnt use the DoDataExchange() function thou.
