Combo Box & Mouse

[Jody Kelsch]

Is there any way to stop the highlighted item in a combobox from changing
when the mouse is moved over the list portion of the combo box? I want it
only to change only when the user actually clicks the combo box or pressed
the arrow keys. (Just like the VB16 Combo Box.)

Thank you,

Jody:

I'd probably do it by subclassing the drop down window and throwing away the
mousemove events.
Of course, that's also easier said than done. You'll have to get the handle of
the drop down window using API
techniques. Then it might be that you'll need to use a hook rather than
subclassing depending on how the
control responds to the message. But ultimately it should be possible to do.

Our SpyWorks package (www.desaware.com) has example code that is similar for
working with combo boxes.

Best of luck

Dan
