I am currently trying to set a CComboBox* with the ID that is assigned for existing combo box(IDC_COMBO).
I've tried CWnd's GetDlgItem() and ID assignment, but I could not figure it out yet.
I know this isn't exactly the expected details, but this is all I can give you.
Is this what you want?
CComboBox* pCombo = reinterpret_cast<CComboBox*>(GetDlgItem (IDC_COMBO));
