RE: [Dev-C++] Creating controls based on a database

[P.D. v. Z. <pa...@my...>]

Well that should be easy.
You could for instance use the row's ID (from the database) as the
identifier (and add a fixed number to it so you know it won't conflict
with your other controls).
It's usually wise to maintain the original database ID anyway, since you
will probably want to do something with that data later, and maybe even
INSERT or UPDATE it, in which case knowing the original ID can save you
a lot of headaches.

Well, of course it will be in a loop. I just don't know how to create
the checkboxes (and other controls) from within the loop, keeping them
distinct (non-static).

Well this could be handled in a loop or something. Call your function
based on CreateWindowEx as many times as there are rows or whatever in a
table. The function checks if it must create a checkbox or another
control. Does so and places it correctly.

Well that is how I would do it.

Yes, but what I'm not sure is how to do an indeterminate number of
controls, based on whatever is in the database. Say I pull up 10 rows;
it should work the same way if there are 5 or 30.

I'm not 100% sure but I think you should or could use CreateWindowEx
(win32
API) to dynamically create any kind of window (control). Look it up in
the MSDN lib.

I'm using the (Microsoft) Win32 API - sorry about that.

If you had specified that up front, people would be able to provide you
with samples.

Hi all -

I have a fairly straightforward requirement: query a database table,
then generate checkboxes and labels to correspond to each row, with the
checkboxes remaining non-static. For example, if my data consists of
names of people, I want to add controls to my form like:

[] John Doe
[] Suzie Q
[] G. W. Bush
[] Jacque Chirac
...

([] represents a check box)

Assuming I know how to query the database and store the data in an
array, how would I use this array to create these controls? Thanks!

-Ed
