Assigning Array variables to a list box

matthew.macdonald-wallace

Hi all,

I'm trying to add functionality to an app written in C# so that a list
of people is displayed in a list box on the left hand side and then
selected individuals can be added to another list box on the right-hand
side.

I've got the data from my database into a database reader and I can get
it into an arrayList, however I can't get it to do what I want! :)

Basically, I want to use the unique index of my database as the index
for the list boxes, so that I can add a unique ID to the listBox with
an assigned value, the value can be selected, transfereed to the second
Listbox (along with it's value!) and then the database can be updated
accordingly.

Any advice is welcome,

Cheers,

Matt

It would be a lot easier if you were working with objects. Examle if you
have a Person class having all the necesary properties, then you would
override ToString() method of your Person class. Then all you need to do is
add the instance of Person to the .Items collection of listbox (ie:
listBox1.Items. Add(person1) ).

Then by grabbing all the selected items from your first list box, you can
add them to you second listbox ie
(listBox2.items .AddRange(listb ox1.SelectedIte ms); ) And when you need to
update your database, you can cast the objects back to Person type, which
will give you all the properties of the object.

hope this helps

When does assigning variables become more efficient than $_POST

by: dSchwartz | last post by:

This may not be a big deal, but I'm just kinda curious. If I have a page that submits a form to itself, when is it better to assign each element in $_POST to a variable to use for the rest of the page? My situation probably doesn't make a difference, but say I have about 10 form fields, and when the page is posted back to itself, i call each of those form fields 2 times (1 for error checking, 1 for SQL insert, or to pre-fill form). ...

Looked all over for the answer to this but can't find it. Maybe I'm searching for the wrong thing. I'm new to using classes in PHP.

I'm sure I'm doing something incorrectly with the assignment. function LineGroup($classarray) {
