Collection to listbox

[Brian Henry]

I have a simple problem... I am makeing a journal which has a collection of
entries (journal class and entries class).. when you select a journal i need
it to show in a listbox all the entries (the title of the entry) which is
easy.. but I also need an ID for the item so i can tie to to a database
entry.. is there any way to bind to a collection? or better yet set a value
for each item in a listbox kinda like data binding does with the value
member.. thanks

You can set 'DataSource', 'DisplayMember' and 'ValueMember'.

but to a collection? how would i do that?

You can set 'DataSource', 'DisplayMember' and 'ValueMember'.

If the data is, for example, stored in an arraylist:

\\\
With Me.ListBox1
.DisplayMember = "Name"
.ValueMember = "Age"
.DataSource = Database.FindPeople(...)
End With

Brian,
As Herfried stated, you set the 'DataSource', 'DisplayMember' and
'ValueMember' properties of the ListBox.

Have you tried something like:
Dim list As ArrayList
Dim lb As ListBox
lb.DisplayMember = "property1"
lb.ValueMember = "property2"
lb.DataSource = list

Where Property1 & Property2 are properties of the items in the collection,
if you do not set DisplayMember & ValueMember, then the ToString method of
the objects in the collection will be used.

For further details see the ListBox.DataSource (inherited from
ListControl.DataSource) property in MSDN.

Hope this helps
