property method. I have created a new class derived from the Forms.Listview
and I cannot figure out the syntax to override ListView.Items.Add(), . I see
that it is a virtual method so it should be easy to do. If anyone can help I
would appreciate it greatly. I can do what I need to do in a different way

Hi,
I 'm facing an interesting issue regarding a property and its TypeConverter.
When i do not attach a TypeConverter to this property, all custom
properties of my custom control are displayed in Test Container.
Since i attached this TypeConverter to my property, ALL custom
properties (properties implemented by myself) are not displayed in Test
Container.

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.

For most users, this new feature is actually very convenient. If you want to control the update process,...
