Hi,
Hope someone can help. Here's the scenario:
I have two MSAccess tables MainTab and SubTab. MainTab has an autonumber
'id' column as primary key. Subtab has this id column as a foreign key.
There is a one-to-many relationship defined on MainTab and Subtab using the
id column. The join type is include all from MainTab and only rows with
matching value from SubTab. Referential integrity enforced; cascading

Hi all,
Here's my situation:
I have 2 tables, let's call them TableA and TableB. TableA has a primary key
called AffNo, TableB's primary key (--> foreign key in TableA) is called ID,
and is Autonumber.
I want to do a form to input information for TableA, with a subform for
TableB where i can enter several records concerning TableA. This seems to
work, however, whenever i click on the 1st Field in the TableB subform, it

Hi everybody,
This time a very very difficult case:
I have a table "tblStudent", there are 50 students, I also made a form
"frmStudent" based on "tblStudent", now if I don't want to show all the
students in a classical (vertically, from top to bottom) way, but make them
"sitting" in 50 text boxes, 5 rows 10 columns, how to do it?
Thanks in advance.

Sometimes I use Autonumber fields for ID fields. Furthermore,
sometimes I use those same fields in orderdetail type tables. So it's
important in that case that once an autonumber key value is assigned to
a record that it doesn't change. Occasionally I find that due to
corruption or an accidental deletion and restore of a record from a
backup the autonumber field needs to be tidied up. So when I create
(through AddNew) the autonumber...

Hi all.
I have a datagrid that has several columns including the Primary Key as
the first column.
When I add records to the grid the Primary Key column show "Null". This
would not be a problem, but I want my users to be able to delete the
column right away if they made a mistake with the entry. If the Primary
key is null I can't access the dataset to get the ID number of the row
to delete. Is there a way to refresh the datagrid...

I'm having a problem with a form that uses AutoNumber as the primary
key. I have an Abort button to delete the current record and close the
form. If AutoNumber is assigned, the code executes a SQL statement
that deletes the current record. I need to be able to detect when
AutoNumber is unassigned (a new blank record) so that I can simply
close the form without running the SQL delete statement.
Unfortunately, no tests I can think of...

To comp.databases.ms-access --
I just discovered, to my more than mild dismay, that some tables in my
Microsoft Access 2003 database have duplicate numbers in the
"AutoNumber" field. (Field Size is set to "Long Integer", and New
Values is set to "Increment".) I know that an old version of the Jet
database engine can cause this problem, but my version of msjet40.dll
is 4.0.8618.0, which is supposedly bug-free in this respect. I am...

Hello All,
(newbie)...I'm working on an Ordering app using the typical tables (customers, orders). I have a Search form to find existing customers prior to entering a new order. On the search form there's a combo control called 'custname' so that when a customer is located, the existing customer name is filled in and the account number goes into the Account control (from an autonumber field called CustomerID from Customer table). The rest of...

Hello,
I have a data entry form for a table with information about buildings and am having a problem making a combo box do what I want. I would like to make the combo box show a list of unique bldg mgmt company names and then to open a building management company form to show all records with this name, so the user can find the correct branch location to select.

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,...
