Why are you adding Labels to a ListBox? What are you trying to achieve with this?? i can't think of any good reason to do this.

You spelled "Experiment" wrong.

I am surprised that this builds and runs. A list box Items collection is a collection of ListBoxItems, I'd have thought. This is winforms, it's not WPF.

You wouldn't think it was the season of goodwill, given the responses from the first few people, would you? OK - your problem is that, while ListBox items are a collection of Objects, it has no idea how to display a label - so you get nothing. Your code will show (in label1) that the items are added to the collection - if you want to draw each in a different colour, then you will have to help the listbox by drawing each item yourself. See here[^] for a quick and dirty example - it should give you the idea to work on anyway. And to the other responders - why the -ve attitude, guys? Time to pull some heads out of some arses, I say!
If I knew then what I know today, then I'd know the same now as I did then - then what would be the point? .\\axxx (That's an 'M')

Because there's just wayyyyy too many people running around trying to do stupid things for the most insiane reasons and we're kind of tired of wasting our time on something that doesn't solve the real problem that the user didn't tell you about. You haven't been around here for the last 5 years watching the quality of questions just plummet to unbelievable levels. I blame it on the outsourcing boom, which generated a huge demand for computer jobs in third world countries where the number of PC's per capita is so low that it could not possibly generate the level of experience required to support the West's hunger for IT personell.

2006, 2007, 2008OK - I can see your point (and your response, frankly, wasn't the worst) but it was pretty obvious to me tha the OP had a simple conceptual problem - I have a collection of objects in a list box, I am adding labels to it, and I am not seeing anything. Now you said "Why are you adding Labels to a ListBox? What are you trying to achieve with this?? " Q 1 and 2 are good questions - by assumptions may be erroneous and further clarification would be good (in case he doesn't just want colourful items in the listbox, but has some other goal) but your statement "i can't think of any good reason to do this. is, I feel, negative and, frankly, pompous. The OP has, it seems, made a mistake in trying to achieve something (presumably colourful items in a list box) and rather than taking a positive approach, you come over all uppity. And no, I haven't "been around here for the last 5 years watching the quality of questions just plummet to unbelievable levels". However, if this has been the general level of response in some attempt to get a better standard of question - then it plainly isn't working. It's astonishing how politeness can often get better results than snideness. How a positive attitude can elicit the same. Do unto others, and all that. I remember in my programming youth I would have killed for a site like CP. I'd hate to see people not using the site for fear of humiliation.
