I must be missing something here. It's clearly faster to lookup an item
directly in a dictionary than to scan through a list. So when I have a
large lookup table I always load it in the form of a dictionary. But it
seems a waste. I end up having to assign an artificial value to the
dictionary entry. Below I assign the value "None" to each...

Hi all,
My application uses a lot of lookup tables.
I've splitted the frontend (forms, reports, etc) from the backend (data).
The database has around 10 different users.
The values in the lookup tables are not likely to change.
Question 1: Should I include them in the backend (with rest of data) or the
frontend?

I have a problem which I know there is an answer to but have so far been
unsuccessful in finding it. It is quite simple in theory. I have created a
form which uses a table for lookup values and they appear on the form as a
list box. I know I can restrict to list or not within the table, but what I
want to do is to be able to add to the list if...

I am used to VB6 but need to develop something in .Net.
I need to create several bound combo-boxes which will use lookup tables to
get their values.
I created a form using the dataform wizard. As part of the setup, I
specified a new dataset, which included the data & lookup tables. I also
specified the relationships when required.
I...

whether each person prefers cats or dogs. I could do it one of three ways.
1. A plain text field
Create a text field in tblPeople called PreferredPet.
2. A lookup field that stores text values.
Create a text field in tblPeople called PreferredPetID and use it to...

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. ...
