Suppose we have an object hierarchy in XSD.
For example, let us take Control, Label, TextBox and LinkLabel windows
controls.
Each control has some properties which are represented as elements.
Some of the elements are of complex types as well, like bounds - of type
rectangle.
(See full example in the bottom of the letter.)
DataSet.ReadXMLSchema fails to parse such XSD file.
The problem is caused by complex type as an element of the...

I am attempting to print out a table using a repeater in which one field is
updatable. Basically you would have a table of x number of rows and y number
of columns. However: only one field in each row will be updatable. My
thought was to build a repeater and then one of the <ItemTemplate> would be a
textbox where the user can update the values in each.
How would I go about in the code-behind to reference each textbox? My
texbox...

plugins handling different kinds of content.
What I really want is to be able to load/unload plugins on the fly
without restarting the application.
What I did was to create an AppDomain that loaded the plugins and
everything was great, until I tried to pass something else that strings
between the domains...

Hi
I'm trying to create a control with multiple regions that can be
edited - maybe as templates I guess.
I've seen a control that was done by Scott Mitchell which has rounded
corners surrounding the control - here is a link to the page
http://aspnet.4guysfromrolla.com/articles/081104-1.aspx) and this
essentially has one editable region that will then be surrounded by
the borders.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
