    How do you dropdown a Combo Box when clicked?

    I have a dropdown combo box on a dialog. Of course, clicking on the dropdown "arrow", the dropdown list opens as it should. If you click on the actual text in the dropdown BEFORE it dropsdown, the text just highlights. How can we force the combo to drop down (open) when the displayed text is clicked on?

    Thanks ahead of time....

    Trap for the CBN_SETFOCUS message then send a CB_SHOWDROPDOWN message to the combo box.

Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent.

    ... or if MFC is used, the CComboBox::ShowDropDown can be used

    This is normal behavior for Dropdown combo (CBS_DROPDOWN). You may try to change the combo style to Drop List (CBS_DROPDOWNLIST) unless you still need the text to remain selectable.
