"not upto the mark"
Means what?

Not a good idea to modify how controls are expected to works. People will hate your application.

1 solution

A common method would be deriving your own class from the MFC control and handling the message there using PreTranslateMessage (untested):
BOOL CMyComboBox::PreTranslateMessage(MSG* pMsg)
{
    return pMsg->message == WM_MOUSEWHEEL ? TRUE : CComboBox::PreTranslateMessage(pMsg);
}

In that page I have Clistctrl also for that also it is disabling mouse wheel. How to make it specific for CCombobox. Thanks

You have to derive you own combo box class (named CMyComboBox in my example) and handle the message there.

You may also handle it in the dialog class (which seems what you have done) but must then check which control is the recipient of the message and filter the message only when it is for the combo box(es).
