Edit Control MFC vc++

The same as the answer to your question below on validating edit controls.

As Victor said, the simple way to achieve this task is to use CEdit Class | Microsoft Docs | ShowBalloonTip[^]

in .h file :

afx_msg void MyDlg::OnEnChangeEdit();

in .cpp file :

BEGIN_MESSAGE_MAP(MyDlg, CDialogEx)
ON_EN_CHANGE(IDC_EDIT2, &MedicationDlg::OnEnChangeEdit)
END_MESSAGE_MAP()

void MyDlg :: OnEnchangeEdit()
{
CString temp;
//could you give some some direction on how to get the text entered in the edit control
// Should I use the control value variable of the edit control to save the input
// I am confused here, I would like some direction. Thanks
updateData(TRUE);
temp = m_editvariable;

Function(1st parameter, temp) // this function will check the text entered in the edit control, with the default value and display appropriate message
}

Thanks.

What kind of object is m_editvariable ?

I have edited like the below code. Only the first character I type shows in message box. What I wanted was the whole thing i type in the edit control. eg. when I try to enter 300, the moment i type 3 message pop up with 3.

void MyDlg::OnEnChangeEdit()
{
CString temp;
m_Edit.GetWindowTextW(temp); // CEdit m_Edit;
MessageBox(temp);

Function(1st parameter, temp);

}

You can associate a CString value with your edit control, and there you will have entire edit value. VS wizzard allow you to do that.

Could you give an example. Thanks

In header:

public:
//{{AFX_DATA(MyDlg)
enum { IDD = IDD_TEST_FORM };
CEdit m_Edit1;
CString m_sEdit1;
//}}AFX_DATA

in cpp:

void MyDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(MyDlg)
DDX_Control(pDX, IDC_EDIT1, m_Edit1);
DDX_Text(pDX, IDC_EDIT1, m_sEdit1);
//}}AFX_DATA_MAP
}

so you have the value of edit control inside of m_sEdit1. Example:

void MyDlg::OnEnchangeEdit()
{
updateData(FALSE);
Function(1st parameter, m_sEdit1);
}

Thank you . The example really really helps. :)

It was a typo. I've changed it. Thanks :)

Use 3 radio buttons; default select the first option (1L). Or leave it "empty" (tri-state) and warn if no selection made. Standard stuff that everyone recognizes.
