MFC, CEdit En_Change get Current Ctrl ID

Question

Hello,

Before I begin, let me tell you that Microsoft Q & A forms was totally Sh**, if you compare to MSDN forms. It's the third time a re-begin this message because Code Block window give some trouble when it's time to edit.

• Back space not at the good place. You will out Code block and still backspace inside. Select around text and erase it.
• Don't try Ctrl-Z, you gonna cry
• Copy/paste inside block Split code block in two
• I never feel so frustrate to send a post.

Ok..

What I try to done it's plug EN_CHANGE to the same Function. Unfortunately this message map have no input parameter like OnCtlColor, that you can call pWnd->GetDlgCtrlID(). Does it Possible to get IDC (#1)?

BEGIN_MESSAGE_MAP(CTopSleeveDlg, CDialogEx)
//{{AFX_MSG_MAP(CTopSleeveDlg)

	ON_EN_CHANGE(IDC_EDTCENTER2CENTER, &CTopSleeveDlg::SameFunction)

	ON_EN_CHANGE(IDC_EDTSLEEVETHICK, &CTopSleeveDlg::SameFunction)

//}}AFX_MSG_MAP
END_MESSAGE_MAP()

int CTopSleeveDlg::OnEditChange(int Index)

{
UpdateData(TRUE);

double Value;

long hr = m_piLogic->GetValueFromExpression(m_Param[Index].Expression, &Value, m_Param[Index].UnitType);

m_Param[Index].IsValid = SUCCEEDED(hr) ? 1 : 0;

return m_Param[Index].IsValid;

}

void CTopSleeveDlg::SameFunction()

{

#1 Get IDC of current Control;

for (long i = 0; i < m_NbElem; i++)

{

	if (CtrlID == m_Param[i].IDD)

	{

		OnEditChange(i);

		break;

	}

}

}

/*** To Remove

void CTopSleeveDlg::OnChangeEdtcenter2center()

{

OnEditChange(0);

}

void CTopSleeveDlg::OnChangeEdtsleevethick()

{

OnEditChange(1);

}

Answer 1

Try this:

const MSG* pm = GetCurrentMessage( );
int id = LOWORD( pm->wParam );

Answer 2

You can use the ON_CONTROL_RANGE message map macro. You must manually insert it into the message map. The range of control id's must be contiguous. For example, in a dialog that has two edit controls IDC_EDIT1 (1000) and IDC_EDIT2 (1001) -

ON_CONTROL_RANGE(EN_CHANGE, IDC_EDIT1, IDC_EDIT2, &CMFCRangeTestDlg::OnChange)

Header declaration -

void OnChange(UINT nId);

Implementation -

void CMFCRangeTestDlg::OnChange(UINT nId)
{
    TRACE(_T("Received EN_CHANGE from control id %d\n"), nId);
}
