For an owner drawn list box,
I have a collection that represents some graphics objects in my app.
I inherited the collection class from collectionbase.
It would be nice to somehow just set the lstbox.datasour ce=mycollection
and have it work, but this seemed to never work so I just run through my
collection and popualate the list.
This is a real waste because the collection contains classes that have one
property that is a bitmap. There won't be many of them but still this is
duplicating memory.
Anyone know a way to make a collection class that works normally and also
with a listbox?
Remember I owner draw each item.
Thanks,
Shane 3 1706
Hi,
Try setting the displaymember in addition to the datasource. Remember
the displaymember can be any property in the class held in the
collection.

hmm..
The thing is. I have a class lets say
clsGraphicObjec t
and a collection class
colGraphicOjbec t
inherits collectionbase
which has a list of clsGraphicObjec ts
I want to set listbox data source to this colGraphicObjec t's Items,
but also the result is not a string, but in clsGraphicObjec t, there is a
picture property that is a bitmap--that is what I want to display in the
listbox.
Will this still work?

Hi,
Sure the listbox item is an object not a string.

Hi All,
I was trying to apply databinding to a custom collection as in the MSDN

problem is that the collection contains a collection as one of it's member

I has a sp used as a datasource bound to a dropdown list. It has a column i
need to set another value on change. The value is not the value property of
the DDL. how can i get to the value in the datasource? I guess i'm hoping it
has a default view associated with it (the datasource). This is, of course a

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
