Hi,
Am I right that indexed properties are implemented in VB
..NET, but NOT in C#. It seems that for C# you have to wrap
the property in a separate class, for emulating index
properties.
In addition in VB .NET you can use indexed property, but
with only an integer as indexer. So, a string as indexer (as
in VB6) will not work here. Is that right ?

Index properties in C++ class libraries (.NET) apper as set_ and get_ methods when used in C#
To test this out, I changed the example from section "13.2 Indexed Properties" in MSDN, and placed the Employee and Manager classes in a library. Then I wrote a C# application implement the code from main(). What happens is that everyting works fine except when trying to call the indexed properties
Example
The following line does not work (as it...

I would like to use an indexed property to access my private array of user
controls. If I don't use an indexed property, the property will show up in
my Properties Window during development. Is there a way to get this to show
up in the properties window?

Dear friends,
In my current project I am using the CustomCollections with the help of
BindingList<Tgeneric class to store the database records instead using
DataSet objects as offline database identities.
Now I do have a large number of property classes each having a large
number of properties in it.
I want to implement the INotifyPropertyChanged interface in every

Hi,
I'm not sure if i'm misunderstanding how INotifyPropertyChanged should
work but it's not working as I expected.
I have a sample program with a very simple 'Customer' class with three
properties code, name & address. All these are bound to a form via a
BindingSource and fire the PropertyChanged event when the property is
modified.

Having a hard time phrasing this in the form
of a question...
The other day I saw a thread where someone asked
about overrideable properties and nobody offered
the advice that properties are Bad. So maybe we've
got over that. I suppose properties could have
Bad consequences if a user doesn't know they exist
and think that a certain property of an object is
just an ordinary attribute. But that applies to

Okay say we have a class that implements INotifyPropertyChanged and a property that has code in the setter to raise the PropertyChanged event. On the GUI side we have a text box with the code:
txtFirst.DataBindings.Add("Text", p, "FirstName", True) Where p is a Person object and FirstName is the property that raises the PropertyChanged event.
It works perfectly when I programmatically change the object's property or using the application,...

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...
