Oh, not sure if this makes a difference, but I'm not actually working with database files here. I'm using a text file, reading line by line to populate the object properties. Most information I can find on datasource has to do with databases. ----- Original Message ----- From: Ken Perry To: programmingblind@xxxxxxxxxxxxx Sent: Saturday, August 15, 2009 10:02 PM Subject: RE: C# question, binding arrays of objects to a list box, can it be done? I would have to try this but if you do this in c# data source can be anything from an int to any kind of structure you want. So you could just save the index in the list of data structures in data source or you could actually use the list box to save your data structures in the data source field.

Ok, let me see if I can explain the problem. I have a feeling I'm missing something obvious here, but I had a similar hang up in one of my VB assignments so, who knows. This assignment is to create an address book application. The user is supposed to have the option to show a list box with all entries listed, but only show the last name and first name. The full entries include first name, last name, address among other things. The list box also must be sorted alphabetically. We're reading the initial entries from a file, but allowing for edits, additions, deletions, etc. The way I'm doing this is that I created a class called entry, which has properties for first name, last name, address and so on. Then I have an array of entry objects, so that for example to get the first name of the third entry, I could use entries[2].FirstName. So far so good, but I'm at a loss for how to get the information I want into the list box in such a way that the first and last names displayed there will stay connected with the rest of their object if deletions and edits are made. I keep thinking that datasource should play a part here, but when I research it it's either not what I want, or the explanation is way over my head. So am I going about this all wrong, or am I just missing something simple? One thing I considered is keeping name as a single property rather than trying to pull two different properties into the list together, but that still doesn't solve the problem of how to keep everything together when changes are made through the list. I hope this makes some kind of sense, I know what I want to do but not how to explain it well or how to get it working. Any ideas would be greatly appreciated. ------------------------------------------------------------------------------ No virus found in this incoming message.
