Hi guys,
I'm trying to load a class instance dynamically, and then cast it to it's
base type so I can use it in my app.
More specifically, I'm dynamically instantiating a
System.Web.UI.WebControls.RequiredFieldValidator and attempting to cast it
into an IValidator and/or a BaseValidator. Both casting attempts have
failed miserably, throwing an InvalidCastException ... how can it be i
cannot cast to the base class of my instance ???

Hi,
I have an old problem which I couldn't solve so far. Now I have found a post
in that group that gave me an idea, but I can not fully understand it.
The problem is: I'm trying to use a Windows.Forms.UserControl in a COM
environment, i.e. I want to host that control in a COM host. So far, so
good, I can host it, but I can not reach the parent COM object from the
control (Parent property is null :( ).
I have stopped the control in the...

I am seeing that our CPU spikes for several minutes at 100% for the asp.net
process. This happens several times a day and seems to last for 10 min or
so and use a lot of memory. I'm trying to find out what page it is that is
causing these problems. How can i find out what pages are executing at the
time of the spike?
Thanks,

We use a custom versioning scheme that includes the date and time
(2.0.10271545). The version number is displayed in a footer user
control, which is rendered in every page. The web application is in a
web farm. Would there be a significant performance increase by adding
it to the global cache object, instead of reading the version info
every time through reflection for the version that's set in the
AssemblyInfo file?(Instead of just the...

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

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
