CComboBox OnDropDown, how can I cancel the operation...

Hi,


I have a CComboBox, and I want that when the user selects on the DropDown list box button, ask the user for something and if something fails then avoid to show the list box of the combo box ( cancel the "change selection" in the combo box), Is there any way to do that ?


Thanks, Bye !
