ImageList

I downloaded this program, and it works fine like it is.
I then made an application using the wizard in VB5 that
looks like Explorer.
I pasted all of whats in the downloaded program into
the proper places(I'm pretty sure), but when I try to
run the program, I get an error:
(ImageList must be intialized before it can be used)
Do I really have to put in more code to intialize it?
Why does it work in the original like it is?

Code:

What I'm trying to do is make a program just like explorer
except were you can add notes out beside modified column on
the right side.

I guess what you are missing here is that you didnt associate the image list with listview or tree view control that you are using. Right click on the control and change it in the properties.

Doh!!
That was it Thanks.

But now it gave another error:
(Key is not unique in collection)

Any more ideas?

I guess you assigned the same key to more than one image in the imagelist control.

There aren't any keys asigned to any images?

Yes, each Image in the ImageList have a Key and a Tag.

When I pull up the properties window for the ImageList
and go to the Image tab where the icons are there isn't
anything in the Key, or Tab boxes.

Is that where you're talking about, and do I need to
put something in those boxes, because there isn't
anything in them in the original program.
