Hello, I've made a templated class Option (a child of the abstract base
class OptionBase) that stores an option name (in the form someoption=) and
the value belonging to that option. The value is of the type the object is
instantiated with. In my test program I have Option<std::string> and
Option<long>. Here's the code for OptionBase and Option along with a small
helper function. In the code are comments describing my problem, look

I'm having trouble converting a datatable into xml, with resonse.write
to aspx. I'm basically converting vb code that saved a recordset into a
stream into c#, but the format is wrong. I've tried using streams,
datadoc, xmlreader, etc with no success. I need to convert it directly
to a string or via a stream, but not in a file. Here's some sample
code that gives me the bad format. I'll post the good format below that

I have a string that I received from a web service call and I want to write it to a Stream. I cannot figure out how to access the string as a byte array and write it to the Stream. Any thoughts. I looked at Byte.Parse() but it will only convert a string represntation of a number and convert it to a byte.
Thanks,

Hi guyz,
Could anyone please tell me how can I convert an array of floats to a string? I know that I can use this code to convert one float to a string but what is the best way for an array of floats
ostringstream stream;
float a = 3.14156;
// set the significant digits
stream.precision(2);
// by using fixed we specify the number of digits after decimal point.
stream << fixed << a;
string s = stream.str();

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

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...
