gelöscht; ansonsten steht der Zeitpunkt (Tag und Uhrzeit) der Löschung drin.

Hallo,
folgendes Problem:
Zu einer MSDE-Datenbank wird in einer MDB (Access 2000) eine
Verknüpfung zu einer Tabelle angelegt.
Wenn die Tabelle geöffnet wird, erscheinen nicht die Datensätze mit
Inhalt, sondern nur die Meldungen "gelöscht", "Fehler" etc. in den
Datensätzen.

Hallo Power-User,
könnt Ihr mir bitte Eure Hilfe bei folgendem Problem geben:
In einem Formular habe ich jeweils 2 x 12 Datenfelder für
die Monate Januar bis Dezember angelegt (jan1bis dez1 und
jan2 bis dez2). In den Datenfeldern wird jeweils ein Wert
abgelegt, z. B. für Januar 2001 = 1 oder für Dezember 2008 = 96
per Change aufgrund von zwei Jahres-Listfeldern automatisch
eingetragen.

Ich habe folgendes Problem.
Ich habe in ein Formular ein Unterformular eingebunden.
Das Unterformular ist ein datenblattformular in dem maximal

auch ausreichen, allerdings werden ab 4 Datensätzen die ScollBars
angezeigt.

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...

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,...
