Hi,
I'm trying to bind a custom collection class to a data grid, following the
guidelines from the article
http://msdn.microsoft.com/msdnmag/issues/05/08/CollectionsandDataBinding/default.aspx.
The problem is the article is in VisualBasic. I already get the collection
to be recognized as a Data Source by the IDE. It populated the DataGrid
correctly from the fields on the items object of the collection, but I can't
get the DataGrid to...

Hi
Straight to the point - I don't understand why System.Array derives
from IList (given the methods/properties actually on IList).
When designing an interface you specify a contract. Deriving from an
interface and only implementing some of it means something is wrong:
either the interface specification is wrong e.g. not minimal or the
derivation is wrong e.g. the type can't actually honour this contract.

On a form ive added my custom component (MyComponent) which has a property
(IDs in the expample code) exposing a collection of int16. I see this
property in the PropertyGrid and I dont have trouble adding items to the
collection at design time (using standard CollectionEditor class). I can
Add, remove items at design time, however all the items are lost after a
compilation.

I have a custom collection in my c# winform ui control called Items.
Items is a built in collection type that does not allow itself to be
replace (you can't 'set' the itemscollection in the control).
However, the contents of the Items collection is persisted through
designtime.
Currently this all works except for the following. When you bring up
the custom collection editor and add new items then close the
collection editor.

Hello groovers,
I have a component which i'm trying to add some design time support to. I
wish to add design time support so that a readonly collection of
ToolStripItems can be maintained via a collection editor however i only wish

that maintains the readonly collection can only add ToolStripItems that
already exist on the parent form that contains the component...

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.
This is as boiled down as I can make it.
Here is my compilation command:
