I have a Windows Form Which Displays one record at a
time. The DataTable object which is bound to the Form
Controls only contains the record that is being
displayed. When I need to display a different record, any
changes in the current record are saved to an Access
Database, the DataTable's Row Collection is Cleared and
the New Record is read into the DataTable. (This is done
to ensure that when the User goes to view a record, they

Hi,
I'm having issues with DataBinding. I have a Form with two data bound comboboxes on it. When you select something in one combobox I may {or may not} want to change the selected item in the other combobox. For reasons beyond the scope of this post I need to change the second comboboxe's selected index from within a ColumnChanging event handler. So, inside a ColumnChanging event handler I change the value of the column that is bound to...

Hello
I've few questions regarding ADO & C#:
1) Is it possible to view tata from multiple tables in the Datagrid control
? Most of the examples I see are only for 1 table.
2) In Comboboxes, can we display multiple fields ? For example in a Form of
customers, we have a combo box to select the customer you want to change, so
in that combo box, when they drop down, can we have it to display "First

I have an array of a custom obj which I am trying
to use in multiple comboBoxes without creating multiple
copies, but if I put the datasource of the comboboxes to
the same array, then at runtime if I pick change a combobox,
all of them change to that value. I am guessing that it is
because all the comboboxes are using the same Ilist interface,
and the behind-the-sceens variables.
Now, I could create my own wrapper class to wrap the...

When i attempt to bind to the "Text" and "Value" property of a combobox
on a windows form the value is reset when I leave the combobox. The
comboboxes contain the correct Text and Values. I know this as the Value
property binds correctly on it own. It is only when I bind the "Text"
and "Value" that the issue occurs.
The following sample code includes my custom classes and the Form Clode.
I have several comboboxes and customer classes...

Hi,
I am creating an application which dynamically creates forms depending on the information held in a dataset (which also includes the data the application itself uses). As part of dynamically creating these forms, I need to bind controls back to their underlying tables. This has been successful with textboxes, but I am having a lot of difficulty with comboboxes. Setting the datasource to the bindinglist seems to be ok, but I am having...

I have a Repeater that uses a DataSource that has multiple fields. When the
values of these fields is displayed in the Repeater, there are fields that
are used in combination with other fields as well as by themselves. For
example, there may be a firstname field that is used in combination with a
lastname field as well as by itself. Using it by itself is simple, I have
done that many times. However, is there a way to use multiple fields in...

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:

Here is the code in...

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...
