Hi to all
i have some validation code inside ListChanged event and i have that
collection bound to a grid. If i change a value on the grid the event
fires ok. But if i change a value of the collection directly the event
does not fire :(. Is that standard behaviour?

After Binding a Custom Collection as a Datasource , how is it possible to
remove the
references in the Property event ListChanged implemented by the IBindingList
interface in our Custome collections.
At the moment this is causing a bit of a worry since there ar
Non-serializable references in the Property Listchanged eg.
System.Windows.Forms.CurrencyManager and hence we arent able to pass our
collection back to other layers (physically...

Hello group...
I've created a collection class that implements the following interfaces: IBindingList, IList, ICollection, IEnumerable and ITypedList:
abstract class DataCollectionBase : IBindingList, IList, ICollection, IEnumerable, ITypedList
{
private ArrayList innerList = null;
private System.Type itemType = null;

I have a DataTable which i have added data to.
I have a custom method that prints a DataView of the DataTable out on the
screen. The problem I'm having is, i need to call the custom method
whenever the DataTable is changed.
How can I do this? this is not a standard binding problem, since I need to
call a custom method to paint the items on the screen.
view.ListChanged += new ListChangedEventHandler(this.view_Changed);

I have a DataView (dv) that includes a StartDate DateTime column. I'd like to
return the DataView record that contains a StartDate value closest to my
IncidentDate value:
string filter = String.format("StartDate nearest {0}", IncidentDate);
dv.Rowfilter = filter;
Of course, there's no nearest function.

hi,
I have a DataView which has around 50 items(the page has scrollbars).
there is a search box on top of the page. when user enters an Id, i do
DataView.find("Id"). I get the row index but i need to highlight this
row and set focus on this row. that means my page might have to scroll
down if the id that is searched happens to be the 45th one.
Please help me do this.

Hi All,

I have subscribed ColumnChanged event of the datatable on which dataview is...

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,...

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...
