Hi to all,
I am developing a database where, with time, it proved to be necessary
to keep track of the changes to the data. It is fairly easy to keep
track of the time when a record was changed (afterupdate event)
-> Is there there a smart way of finding out which field has been
changed? I don't want to set a procedure on every field on the edit
form for keeping track of that, because the forms will be changed from
time to time.
Thanks in advance!

Use the BeforeUpdate event of the form, not its AfterUpdate event. There is
no point in dirtying the record again immediately after is is saved.
When you use Form_BeforeUpda te, you can also compare the Value of each bound
control to its OldValue, to pick up the differences.

You can loop the Controls collection of a form; every control that has a
controlsource property also has an OldValue property. If that is not
equal to its Value, the control has changed.

We have about 10 different domains that are linked very closely and we
want to identify and keep track of every single user that surfs our

The problem is how to keep track of the session ID across domains.

Could someone share with me their technique for keeping track of

Hi,
I'm using the VS.NET 2008 website copy tool. It is supposed to keep track of
whether files are new, changed, or unchanged relative to a site on my
"remote" server. Most of the time it does not maintain that information
between sessions and the local and remote window indicates a "?" for the
state of each file. Can anyone speculate why this behavior happens? It
definitely makes the tool less easy to use.

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:

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,...
