Re: [WIN] how make empty combo not "open" (dropdown) if clicked on?

Euman,

Using sendMessage to get the combo count didn't work any better than my
original use of getCount, but that's pretty reasonable, right?  getCount
probably *uses* sendMessage(Combo3,CB_GETCOUNT, 0,0) .  The problem seems to
be that even if it's told by "dummy = sendMessage(Combo3,CB_SHOWDROPDOWN
,False,0)"
to close the list down, somehow the "windows" action of opening the combo on
click predominates, *unless* you make windows ignore its normal action by
Derek's suggestion of returnValue(0) if count = 0.

Thanks for trying, though :)

Dan
