Hi everyone.
I've been working with VB6 for a while now, I'm feeling pretty damn
confortable with it, but find myself wondering about VB.NET and web
applications. So I thought I'd get my feet wet.
Well - let me tell ya - there's a whole lotta stuff that I need to teach
myself. I have a whole slew of questions - to many and propbably just too
basic to go into here - so I am hoping that someone out there can suggest a
book that I can pick...

1. What is System.Windows.Forms.VisualStyles.TextMetricsCharacterSet
good for?
2. Are the Indic scripts supported?
Are all supported scripts fully supported? (for printing and fine
measuring)
Is the printing done by GDI++ without using Unicribe?
3. Is the Text.Encoder/Decoder provided by the OS or by the Framework?

Hi All,
Despite spending the past six to seven hours perusing the docs on the
mySQl site, I still have questions unanswered, and have been unable to
get any help. I am familiar with Sybase, some Oracle and PostgreSQL -
but the mySQL SQL seems a bit "non-standard". I would be very grateful
for any help I get in answering these questions:

Hello,
I have a few questions concerning classes.
1)
Why some people use default constructos, i.e constructors with no
parameters? To me it doesn't make any sense, is there something I
should know? For example, I'd declare a class in a following way:
class Sample {
int number;
string title;

Hello,
If I have a class that has virtual but non-pure declarations, like
class A{
virtual void f();
};
Then is A still an abstract class? Do I have to have "virtual void
f() = 0;" instead? I think declaring a function as "=0" is the same

Restrict keyword questions
How far does the guarantee that an object is not accessed through another
pointer go? I mean, all examples I have seen are simple stuff like:
int f (int *restrict x, int *restrict y)
{
*x = 0;
*y = 1;
return *x;

Hi
I am Saeed Amrollahi. I write C++ programs using VC++ 2005 CLR/CLI. I
have two problems:
1. How to declare/define and use global ref class objects? For example
for database connection/communication, I usually define a class called

and now it wraps the ADO.Net facilities:

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:

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...
