I'm having a problem using the Cache object with asp.net. Here is what I
have:
1) I put something in cache and set its callback method.
2) The object times out after X minutes and calls the callback method
specified.
3) The callback method gets the newest version of the item from the db and
then calls a helper method to put the item back into cache. It looks like
this:

Hi,
I have a config XML file that I am using from the application cache. I have configured the entry with a remove callback to re-populate cache automatically when the XML file changes. All is well until the XML file is changed. The cached item is being removed as I would expect, but the remove callback is not firing at all, hence a NullReferenceException is being raised when I try to access the cache object.
Please see code snippet...

Hey all my second post!
wanted to know if I can cache an entire control.. this is what I have..
Webform has header, nav, footer, and Usercontrol_1. Usercontrol_1 has a
datalist and paging items ( prev, current page, next ).
I wanted to output cache for each "page" of the datalist, but I can't
seem to get it to work ( any suggestions? ). It would only cache at the
usercontrol level. so I'd get the header, nav, foot, and...

I've come across a weird behaviour with regards to the cache object.
I couldn't find any documentation which could explain this.
Basically the problem has to do with the cache item NOT expiring.
If you look at the below code, u'll see that i'm creating 2 cache items with
the keys ONE and TWO.
And both are set to expire in 30 seconds.
When i click the button every time before 30 seconds, i can view the cache
data.

Hi,
Some newbie questions.. :-)
First, what is the namespace to use for the Cache class ?
When I use this bit of code I get an error
if (Cache==null) Cache.Insert("myUserList",userlist);
I don't know which namespace to use.

I have created a custom user control which creates a ASPxMenu ( Same

to cache the menu with the session user as the key. The problem is that
I can not retreve the menu object after the first request. The menu
items are resident in the...

How do I add a string to the cache so that it updates if the string
source changes? CacheDependency() seems to want an absolute path. My
string is a full http link.
Thanks,

Hi
The documentation for System.Web.Caching.Cache states that it is
"thread safe".
Does this mean that if I access System.Web.Caching.Cache from several
places in my application access to the items in the cache is
synchronised so I don't get problems with setting/getting the same item
at the same time?

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
