Hi,
I have the following problem. I analyse data from a file. When I am done
analysing all the data that was in that file, I want to let my program
wait until this specific file has changed (which indicates that new data
has been added to the file from a third party program that I don't
control). If that file has changed, I want my program to continue.
What would be the appropriate command to check if the file changed? And
how can I...

Well, there are a couple ways you could do that.
You could write a windows service with a
System.Timers.Timer object, that fires an event ever 15
minutes. Or, you could use a trigger on the table you are
evaluating. On update for your table, your trigger fires
executing a piece of code that could be a SQL job, or an
actual executable you had written in VB or VB.net. The
easiest programatic way would probably be the service
though.

registry change notification. Must I use the raw API such as
RegNotifyChangeKeyValue, RegOpenKeyEx, and RegCloseKey ?

Hi,
I have a DateTime picker control on a form. The datetime
picker control is data bound to a column in a DataTable.
Yes I know about bound DateTime pickers and DBNull and
etc. so no troubles with that stuff...
However, as somebody out there probably knows,
programmatically setting the DateTimePicker.Value property
to a new VALUE does NOT in itself constitute a CHANGE to

I am writing a little vb/vb.net application to check every
15 minutes if a record or certain records have changed in
a specific table, If record/records have changed then get
the index of that record. What is the best way to
accomplish this task? Any ideas or source code samples
would be highly appreciated.
I am using vb.net with SQL Server 2000, vb6 is also
available to me.

I developing a large project that will have numerous text boxes, datetime
controls, checkboxes etc. all data bound to a
dataset/datatable/tableadapter.
I'm wondering what is the normal way to get notification from the program
that the user has changed some databound item? I know I can tap into the
OnChange event of all these individual controls, however it seems like there
should be something exposed at a more common level.

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,

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

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,...
