Deselecting text in CEdit

[irona20]

I have a dialog with a CEdit and a CSpinButtonCtrl.
This is my code:

void CInformDlg::OnDeltaposSpinLog(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_UPDOWN* pNMUpDown = (NM_UPDOWN*)pNMHDR;
if (pNMUpDown->iDelta == -1) //Arriba
m_strLog = sText1;
else //Abajo
m_strLog = sText2;
m_editLog.SetSel(-1,-1);
UpdateData (FALSE);
*pResult = 0;
}

Where m_editLog is the edit and m_strLog is a CString variable associated with the edit. With this code, the text in CEdit is always selected, and I don't want this. What am I doing bad?
Thank you in advance.

Update your edit control manually...

void CInformDlg::OnDeltaposSpinLog(NMHDR* pNMHDR, LRESULT* pResult)
{
  NM_UPDOWN* pNMUpDown = (NM_UPDOWN*)pNMHDR;
  if (pNMUpDown->iDelta == -1) //Arriba
    m_strLog = sText1;
  else //Abajo
    m_strLog = sText2;

  UpdateData (FALSE);
  m_editLog.SetSel(-1,-1);
  m_editLog.UpdateWindow();
  *pResult = 0;
}

Thank you Andreas. With your code happens the same. When the text is changed in my edit box (with spin control), all text is selected.
