Hi Folks,
I have added a ListBox lookup in one of my access tables. Problem is, my
form does not reflect the changes (in other words, the form does not
display the ListBox). Is there a way to sync up the form so that it
reflects the design changes in my table without rebuilding or editing
the form?
Thanks

One part of a customer project I'm working on involves what seem
like fairly straightforward updates to a set of related tables.
While I've developed software for a number of years (it only seems
like centuries on days like this <grin>), I'm new to C# and ADO.NET
and I'm running into problems with record deletions.
I (think I am) applying ForeignKeyConstraints correctly. I'm not
applying DataRelations (yet), but those _appear_ to be...

Hi-
I've seen this problem discussed a jillion times but I cannot seem to
implement any advice that makes it work. I am porting a large project from
VB6 to .NET. The issue is using the combo box bound to a table as a lookup,
drawing values from another table to populate the available selections. This
all worked fine in VB6.
I have distilled the problem down to a simple form drawing data from the
Northwind database for a representative...

Hello,
For my datagrid I added a datagrid table style to include columns from
my lookup tables. These display the values in the lookup tables rather
than just the integer key value stored in the data table.
When I make selections in bound combo boxes on the form and save the

procedure does not reflect the changes for the referenced lookup tables

I have a 15 LookUp Tables tied to 15 ComboBoxes.
Some of the Tables contain 3 to 10 Recs, and a couple contain up to 50
Recs.
1- Is it a CommonPractice to link the field that gets the ComboBox
result, to the Lookup Table to ensure Referential Integrity and
Cascaded Updates?
2- Also, should the LookupTable PrimaryKey be an AutoKey or the Name
of the main field being referenced, which in my case would average 15

Hi again, brilliant developers. I'm having serious issues with cascading comboboxes. I had it working perfectly before, but then was asked to add an additional variable and everything went haywire (surely due to my incompetence). I've printed out Rabbit's tutorial and read it many times, but like others, I feel I need a more elementary approach. Please let me explain:

Newbie Access developer here, and my first post on this forum, so I might not get everything right - thanks in advance for your help and your patience!

Hello, I have attached a picture of my Access form.
Each record has a delete button beside it, pressing it deletes the record and cascades to the child records. Horray.
Except sometimes, for a reason I can't explain it doesn't work. I have to click off a record then back onto it and it will work.
I'm using the default VB code that access generates to perform the delete
"The table cannot be deleted or changed because table includes...

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,...
