styles

I'm iterating through the controls in a dialog and I'm trying to determine if a combobox was created with the WS_VSCROLL style.

The style, obtained from GetWindowLong(hwnd, GWL_STYLE), doesn't contain the WS_VSCROLL bit (0x200000), even when I know it was set on create.

Clarification: I am looking to see if the ComboBox was created with the WS_VSCROLL style. Calling GetWindowLong() (or using spy++) to get the style of the combo's listbox will include WS_VSCROLL if a scrollbar is needed to based on the current contents of the list.

I am trying to determine if the ComboBox was created with WS_VSCROLL, not if a scrollbar is currently visible.
