Hi.
I'd like to pass as a parameter of class method reference
to ListControl (ListBox or ComboBox).
Here is my call:
public DoSomething(ListControl lc){}
It's ok with that, but lc does not have methods like
lc.BeginUpdate;
lc.EndUpdate
but ListBox and ComboBox does have such a methods.
I don't like two methods like

I have developed a form which dynamically builds textbox, radiobuttonlist,
checkboxlist controls from parameters in a table, and somehow manages to
maintain state (of data keyed in by user). However, the listbox that i
invoke on click of a help button does not maintain state (i am not
re-loading the list on postback , which is a usual problem). Does anybody
have any idea what could be the issue ? The only asp control i have defined

Does anyone know why the ListControl base class doesn't have an Items
property in Windows Forms, but does in Web Forms? This seems kind of
pointless and is really annoying when trying to write a generic procedure
for adding items to a ListControl in Windows Forms (I know I could use the
DataSource property, but I need to be able to add and remove). Anyway, I
can work around it, but I'm really curious to know why that's the case.
Thanks....

I know that this has been asked and answered thousands of times. As a
matter of fact, I know that I need to say
If Not Page.IsPostBack Then
'Do something
End If
for things that needs to be processed by the web server. I am still
struggling to understand this postback logic, and hope that some kind
gurus out there could help me clarify the confusion I have.

Hi guys,
I am converting a rather complicated database driven Web application from
classic ASP to ASP.NET 2.0 using VB 2005 as the programming language. The
original ASP application works quite well, so at times it is tempting just
to port parts of it over mostly as-is. In fact, one MSDN article I read
suggested using straight HTML wherever possible to make the app more
efficient and less resource demanding.
On one page there are 2...

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
