Hi,
We have an ASP.net application, where we dynamically add controls, in the
Page_Load. Occasionally, when the user posts back the page (e.g. clicks Save
button on the page), we get a "Failed to load viewstate" error. This happens
on Windows Server 2003. It happens erratically, and appears to happen after
the application has been running (and in use) for some time. When the
problem arises, it appears to happen more frequently for a...

Hello,
I have applications that produce the following error when they have been
open to long without activity. Is there any way to force a re-load of the
page or go to another page if the page has expired instead of getting the
error?
Thanks,

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...

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,...
