Just curious why a VERY commonly used affect of rollover was NOT implemented
in .NET 2.0 for web controls?
Does anyone have a link to VB code that will show me how to build my own
UserControl that will support a rollover?
thanks, Rob.

Why there is not a built-in function for it in .NET, I really can't answer,
but here is a very simple function I wrote for myself (I did it using 1.1,
but I can't imagine why it wouldn't work in 2.0). Enjoy!
Public Shared Sub AddRollover(ByV al img As Web.UI.WebContr ols.Image, ByVal
rollover As String)
'Adds the rollover feature to an Image or ImageButton (or other class
that inherits from an Image)
img.Attributes. Add("onmouseove r", "this.src=' " & rollover & "';")
img.Attributes. Add("onmouseout ", "this.src=' " & img.ImageUrl & "';")
End Sub

Thanks for the suggestion/code, I ended up making a UserControl, but was
just curious why such a well used feature was not included in .NET 2.0.

I'm not sure, but if I had to take a guess I would say they didn't want to
bother making a whole new class for something that can be done with very
little extra code (you saw how short my function was). I think that some of
their goals were:
1. To keep the properties as similar to those in 1.1 as possible
2. I think they wanted the Image Control to mirror the HTML img tag as
closely as possible, and the HTML img tag does not have a built-in rollover
feature

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:
