I have an ASP.net application using SQL Server 2000 that every once in a

"System.InvalidOperationException: Timeout expired. The timeout period
elapsed prior to obtaining a connection from the pool. This may have
occurred because all pooled connections were in use and max pool size was
reached"
I looked at my code and It seems that I do close every connection that I
open so I don't know why I am getting...

Hi,
I have been playing around with the suggestions and code shown in
http://www.parashift.com/c++-faq-lite/dtors.html#faq-11.14
regarding memory allocation/deallocation (mem pools). I think I understand
what the FAQ was getting at (emphasis on "think") so I concluded that
attempting to make a delete statement on an area of memory that was created
in a pool with the placement new operator (overloaded) would not allow me to

I have created a custom allocator for a multiset, and I am having a
problem it seems because while the allocator has memory available to
be used which is returned, the objects are never constructed on top of
that memory. I expected my "construct" method to be called to handle
this, but no one calls it.
No more than MAX_OBJS object of class Obj will ever be allocated.

I tested the speed of a simple program like this:
//------------------------------------------------------------
#include <list>
#include <boost/pool/pool_alloc.hpp>
int main()
{
typedef std::list<intList_t; // default allocator
//typedef std::list<int, boost::pool_allocator<int List_t;

hi,
I'm looking for an open source memory pool. It's for use on an
embedded system, if that makes any difference. Something with garbage
collection/defragmentation would be nice. It should have the ability
to allocate different size chunks of memory not just a single size. It
should error check for double free, etc. And it should be usable by a
mixture of C and C++ subsystems.
If I get that, I'm happy. Thank you very much.

I am creating a large graph object in which I add nodes whenever I
need them, and I create them by 'new node' individually. I know this
is slow if I am going to allocate thousands of nodes individually. I
want to replace this allocation by an allocation from a pool. One
simple method I can think of is a manual allocation of a large array
of nodes (since I have an estimate of how many nodes there will be),
and use pointers to array...

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:

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,...

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...
