I have a drop-down control and I want to capture the event when the value in the combo box is changed. Here is my code for the control combo box:


CXTPControlComboBox* pComboState = (CXTPControlComboBox*)CXTPControlComboBox::CreateObject();
pComboState->AddString(_T("Win32"));

How can I add event handling to this?

Thanks.
Jessica

Hi,

FROM CustomThemes sampe:

ON_XTP_EXECUTE(ID_EDIT_STATE, OnEditState)

 


void CMainFrame::OnEditState(NMHDR* pNMHDR, LRESULT* pResult)
{
 NMXTPCONTROL* tagNMCONTROL = (NMXTPCONTROL*)pNMHDR;

 CXTPControlComboBox* pControl = (CXTPControlComboBox*)tagNMCONTROL->pControl;
 if (pControl->GetType() == xtpControlComboBox)
 {
  int nState = pControl->GetCurSel();
  if (nState != 2)
  {
   m_nState = nState;
  }
  else
  {
   MessageBox(_T("Configuration Manager"));
   pControl->SetCurSel(m_nState);
  }
  *pResult = TRUE; // Handled
 }
}
