Creating a .frm interface for a query

I believe Bertil Isberg sent me instructions for accessing a query
through a form quite a few years ago. I didn't gt around to it then,
but I really need to get to it now.
The standard query tapeworm is too long for my daily use. I have
looked at some of the commercial options available, and they are not
ideal, either.

I thought the instructions were on the DBcommunity, but didn't find
them there.

Thank you.

"Standard query tapeworm"?   Whatever could you mean by that?

Not sure what you're trying to do - accessing a query through a form?  If
you mean having a form window that provides selection criteria entry fields
on it and a push button to generate the results based upon those, it's
pretty simple - if you do opal.  If not, then you be learning soon.

Is that what you want to do?

I think that's exactly what he meant.. the raw query form stretches out
forever.. *if* you have too many fields in your table (g)

and I also think you gave the correct answer.. sure, you can create a form
that'll let you make criteria selections, then pass it to the query.. *if*
you know how to write paradox code..

never pictured it as a tapeworm before.  Now I'll never forget!

so - if that's what you want jlynn, let's hear so and I'll sketch something
out for you.

They make good pets.
They go where you go, eat what you eat.....
=)

Which reminds me of eating fried mozzarella sticks,
it seems to be one of the only foods you can eat
where part of it is in your hand,
and the other end is in your stomach.

You can floss your throat if you seesaw it back and forth.

Anyhow......
I have created forms for ad hoc queries in applications.

I put a field on the form,
and added a select table code to a button next to the field.

When a table is selected,
a list box on the left side of the form is populated with the fields.
Initially, I populate the list with fields in position order,
but provide two small buttons under the list box,
to toggle sort order of the list box between position order
and alphabetical order.
This is helpful with tables that have a lot of fields,
and helps people who did not design the table,
or people not intrically familiar with the table design.

When a field in the list box gets clicked,
I add that field to mro object on the form.
The mro object has 2 columns,
one to put the name of the field,
and then one for the user to type in the criteria for the query.

Then when I click a "go" button,
a query gets created behind the scenes.
When I have used this simple technique,
I usually insist that the query return all fields in the table,
and do not do calculations in the query.

It is primitive, but has been handy several times.

The worms go in, the worms go out,
They go in your belly and come out your mouth...

Sorry 'bout that - couldn't resist!

The worms go in, the worms go out,
The worms play pinochle on your snout.

(GO IN your belly?  Is this for a corpse or something? :-) )

Yeah, yeah, but where did they get the cards? And how do they shuffle w/
no hands?

Well, that's the real interesting part of the story.

You see, they line up along the nasal passage, and coordinate
releasing their cards with the inhaling and exhaling.  There is a
group who randomly pause a card and then re-release it so the order of
cards changes.  A group is also assigned to catch the cards as they
come cascading in.  Another group slithers the resorted cards, stuck
to their backs with a bit of mucus, back up and out the snout.

Where did the cards come from?  The last I heard the belief was that a
charity church group donated them for the entertainment value on
Thursday evenings.  Another group believes the cards were donated by
Boy Scouts.  Most hold that as complete wild speculation.

Wow, I learn something almost every time I come here!

Now, (purely to satisfy my scientific curiosity, you understand...) how
do they detect the card suit and value, since they have no eyes?

400+ fields?
