I have a bound textbox (bindings are set at design time) to a dataset
column. Sometimes the value of this textbox must be set so that the
underlying database field gets updated to null when using the update method
of the dataadapter.
Since the dataset field datatype is INT32 it gets set to the empty string
equivalent which is 0. Zero is not a valid value so the update fails.
Can this be done without changing the SQL of the udpdate...

Hello,
I have an MS Access 2003 Project form in which I need to set the value
of a textbox named 'TestGrade' to the value present after the update
of a combo box currently named 'Combo6'. The data source for the
project is a SQL Server 2000 database.
I have the following code written for the 'After Update' event of
'Combo6'
Private Sub Combo6_AfterUpdate()

Hi,
I'm having trouble getting control data binding to work. As I understand
it, the simplest form of databinding requires three things:
1) A control (say a textbox) on a form or user control,
2) A field or object.member to which you want to bind,
3) A "Binding" object that connects the variable to a property of the
control ("Text" for example).

Hi all,
I need to format screen output for a textbox that's bound
to a datasource. I know how to format the data in a
plain old string, but in this case I'm not sure where
to "sneak" in there to do the formatting.
For example, textbox txtAcctBalance is bound to a
currency field in my dataset, and when the value shows up
on the screen I want it formatted as currency ("C").

Hopefully this is the correct group for this message. My
previous post to (I assume) a non-.net group was not
welcomed.
I have a form with 7 text boxes that are all bound to
fields of a dataset. The form also contains a datagrid
also bound to the same dataset.
I have a button on the form to update the data to the
source.

I have a Windows form that displays a database table in a DataGrid. When you
click on a row, the row's values get copied to bound TextBoxes below, and
when the "Save" button is clicked the database is updated (as is the DataGrid
row) with changed values in the TextBoxes. Here are some observations:
1) When changes are typed into a text box and "Save" is clicked, the changes
are reflected in the DataSet.Tables().Rows().ItemArray value, but...

Suppose:
A TextBox is bound to a BindingSource, which is bound to a DataTable
A BindingNavigator is used to alter the current row being looked at by
the BindingSource
(i.e. Nav's NEXT button is pressed. BS.Position changes from 2 to 3,
Textbox was showing APPLE, now shows ORANGE)
Does the textbox receive any notification that this occurred? If so,
what?

So here's the situation (.NET 2.0 btw):
I have a form, and on this form is a textbox among many other
databound controls. The textbox is bound to a field in a data table
via the Text property. In this table there are multiple columns that
cannot be NULL, which, are bound to other controls (but they're not
really important at this time).
I create a new row via the currency manager like so:
_currencyManager.AddNew()
_currentRow =...

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...
