Here is a simplification of a general design problem I face.
Say you have:

Hi All,
I have the following problem, and I would be extremely grateful if
somebody would be kind enough to suggest an efficient solution to it.
I create an instance of a Class A, and "push_back" a copy of this into a
vector V. This is repeated many times in an iterative process.
Ok whenever I "push_back" a copy of Class A, I also want to assign a
pointer contained in an exisiting instance of a Class B to this

I am creating a HTTPS File Transfer App using ASP.NET and C#. I am
utilizing ActiveDirectory and windows security to manage the
permissions. Why reinvent the wheel, right? Everything so far is
working well with the Active Directory. The problem I am having is
with adding File Permissions to a directory. I am currently using

Hello. I have a custom collection that implements IBindingList (allownew and
allowremove are both true). I have bound it to a datagrid. I have add and
remove buttons on the screen. I want to implement those buttons, but I'm not
sure what the code should look like.
I tried what I thought was obvious code:

Hi all, I have following problem: I'm creating a ListView (Details) control
at run-time and filling it with some records (let's say 10 000). This
operation seems to be quite fast, but when I call Controls.Add(list),
where list is my ListView control, then program hangs for minute. It seems
like this time depends on number of records added to control. So probably
when adding control to my form, those records are actualy added at this time...

Hi, I am trying to get a program working whereby directory and file
names are read into a list. I have been given the original list
structure - it appears that the directory names should be added to the
list, then the filenames added to another separate but connected list
within each directory node.
So far I have the program working in that the directory and file names
are all added to the list, i.e. it currently doesn't distinguish...

I have a ComboBox and a List of objects to popolate items.
I use the DataSource property and not the List collection:
List<foolst = new List<foo>;
//add elements into the list

comboBox1.DataSource = lst;
This work fine, items appear.
Now I have a button near the combo box and I want to add a new element

...does it matter which order?
ie...
I create a table/tablerow/tablecell, I then create a new update panel, I
create a drop down list, I add list items to the drop down list, I then add
the drop down list to the update panel. The update panel is then added to a
table cell, I then create another drop down list, and add it to the update
panel, the table cell is then added to the row, the row to the table.

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...
