I'm experiencing bad performance with certain kinds of match queries. Using
a custom XPathNavigator that wraps the usual navigator I can see that many
more node visits are performed than should be required. My document looks
something like this:
<a>
<b>
<c/>
</b>
<b/>

Hi;
Is there a way from an XPathNavigator object to get an xpath string that
will, when used in a Select(xpath) on the underlying base/root XPathNavigator
return the same XPathNavigator?
In other words, I initially create an XPathNavigator for my entire xml
document. To get an XPathNavigator object who's root is a given node in the
original xml document, there is a unique xpath that will return that node.
The unique xpath could have,...

Hi;
How can I tell if I can call XPathNavigator.ValueAsBoolean safely - without
throwing an exception. I want to take one course of action if the value can
be interpreted as a boolean.
But I din't want to do it using try/catch - I think having exceptions be
thrown when the code is operating normally is very bad - both from a
performance point of view and because it signifiys an error.

I have a C# application that compiles other C# functions on-the-fly depending on user selections. There are several C# functions that can be selected. There is one that takes considerably longer than the rest. This function seems to have an unusual performance characteristic. If it is the first one selected it takes 7 times longer to run than if it is not the first one selected. In other words if I start the application and select this one...

I had a customer call about some C# code they had put together that was
handling some large arrays. The performance was rather poor. The C# code
runs in about 22 seconds and the equivalent C++.Net code runs in 0.3
seconds. Can someone help me understand why the C# code performance is so
poor? I rewote the C# code to use a single dimenional array and the time
went down to about 3 seconds, but that's still no explaination as to why the...

I have implemented in .NET 2.0 a custom XPathNavigator for Xpath filtering
on an object tree. So far it works. While analyzing the performance, I have
noticed a lot of MoveToNextAttribute calls.
A closer look has shown that there seems to be a none optimal evaluation of
attribute predicates such as . It works as expected if there is a
match of the attribute value, i.e. the XPathNavigator calls
MoveToNextAttribute until it gets the ID...

Can anybody show me how to insert a CDATA section using XPathNavigator ? I
have tried the follwing with no luck:
XmlDocument docNav = new XmlDocument();
docNav.LoadXml(xmlString);
XPathNavigator nav = docNav.CreateNavigator();
XmlDocument doc = new XmlDocument();
doc.LoadXml("<DocumentData></DocumentData>");
XmlElement elem = doc.CreateElement(currentNodeName);

I have converted an Access back-end to SQL Server back-end but am
having some problems. The Access to Access application has been
running well for some years.
I have successfully copied all the data to SQL Server and linked the
tables to the front end .mdb (I am not using .adp). Some queries were
performing poorly so I have converted these to Views and linked to
them.
Everything works well with good response but when about 8-10...

Hello everybody,
I'm posting this message because I'm quiet frustrated.
We just bought a software from a small software vendor. In the
beginning he hosted our application on a small server at his office. I
think it was a Fujitsu-Siemens x86 running debian Linux. The
performance of the DSL-Line was very poor, so we decided to buy an own
machine to host the application ourselves.

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...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
