I am developing a VB.net Windows Application in. I have a class 'A'
defined in a class library 'CL_A' and another class 'B' in a different
class library 'CL_B'. Class 'B' has a Public Shared member 'm_A' of
type 'A'. So it is like,
class library CL_A:
--------------------
public class A
public x as String

I am developing a Windows Application in VB.NET that is using two
class libraries CL_A (contains class A) & CL_B (contains class B).
Also CL_A is used in CL_B.
Now in my application when i try to set a variable, declared in CL_B,
of type CL_A.A to another variable, declared in application, of same
type CL_A.A it gives me following error though both types are same.
error BC30311: Value of type 'CL_A.A' cannot be converted to 'CL_A.A'

We have two C++ libraries (Unix Shared objects) with the same class
name and no namespace. Is there any way to load both the libraries and
selectivly create the instance of the class from different library?
e.g. We have class Process in libABC.so and libXYZ.so.
Can I instantiate object of class Process from libABC.so or libXYZ.so
by specifying symbol name or some other way??
I know can do that for global function using dlsym...

I have the need to store some application specific configuration data to be
used by a class library and or a windows service. I would like to do this
in a fashion similar to the way we do with applications and web services
without having to use the machine.config file.
I know that I could use the code below to do this but the problem then
becomes that when using a shared assembly both the assembly and the config
file need to be put...

I have a web application which accesses Class Libraries in another project.
Can I add an "App.config" file to my Class Libraries project and be able to
use that configuration information from my web application which has a

My issue is the connection string to my database. I have been placing it

i'm somewhat of a c++ newbie. i'm linking some static libraries into
my app. it turns out that two of the libraries (from different
suppliers) share a class name; e.g. they both have a class named
'SomeClass'. the compiler/linker is complaining. is there an easy
way deal with this so my app can link? thanks.

Hello!
I created a Class Library project in VS2005. Then, using VS, I was able to
add a connection string to the project settings, which automaticaly created
an app.config file for me.
If I try to access the configuration using
System.Configuration.ConfigurationManager, I get a NullException.
The code:

In the previous version of the .net framework,
system.configuration.configuration manager was available for use in Class
Libraries. I'm now working with VS2005/framework 2.0 and it appears that
this is not an option. Why is this class unavailable now in Class Libraries?
I need it to reference a machine.config key on my webserver.
Thanks.

First question - let's get this out of the way since it might be the
solution to all my woes: Does it make sense to have a .cpp file for a
class that is declared as having pure virtual functions in its .h file?
Here's my predicament. I'll put this in general terms since it's
happening across several classes.
I have a base class, let's say it's named A. In A.h I DECLARE several
pure virtual ( = 0) functions, a virtual destructor, and...

Greetings,
I am trying to create a class library/dll with C++ and I am running
into a lot of trouble. I know that this is a C++ forum and not one
specific to windows or VS 2005 but I'm hoping someone call help me.
I would like to create a class library so that I can put classes that
I reuse a lot into their own modules. I played around with it for
awhile and had no luck. It was really easy to do in C# but C++ does
not seem to be so...

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,...
