I have been doing some reading on dynamic bindind and polymorphism. I
know the basics from what I have seen in books. The way virtual
methods were explained was that they were used when methods the same
methods were inhereted into 2 objects and they are parents of new
objects.
I would like some situations where polymorphism is useful.
My next step will to try to understand handle classes.

strange runtime errors. Apparently, throughout the ASPX pages, the VB

DataGrid. Apparently though this works fine in VB.NET, for some reason C#
chokes on it. I have found that replacing those expressions with <%#
DataBinder.Eval(Container.DataItem,...

I prefer to programmatically create the GridView Column/ TemplateField

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:
