combo box has no list box

Brain cramp #1423:

This sounds like a "duh!" problem, but the answer eludes me so far.

I have a combo box on a CPropertyPage. I have loaded it with desired
items both in the resource editor and in OnInitDialog. (Using just the
resource editor didn't work.) (It just occurred to me that I haven't
tested the dialog template.)

I cannot drop-down the list box to see the available selections, or
select with the lbutton. I can select the edit control and use the
arrows to move through the control's items and thereby select one, but
that doesn't cut it.

Why can't I get my list box to pop-down?

You list portion has a negligible height. In resource editor, click on drop
down arrow and then resize the bounding rectangle. You can then test it in
the editor itself to see how it looks.

This is a common error. In your resource editor, you probably didn't size the
dropdown portion to be any taller than the control's edit portion. Click the
down arrow in the editor, and drag the drop list portion to the desired height.

Thanks. I DID try to re-size the control, but using the handles around
the edit control. It didn't seem to let me grab a vertical one. I'll
try it again after clicking the drop-down.

As several others pointed out, you didn't set the height. Since I find
doing this in the dialog editor ugly and always unsatisfactory, I
invented my own CComboBox-derived class which always adjusts its
height on the fly. You can download this from my MVP Tips site.
