imagelist won't work in specific project

[mgarner1980]

Hi,

I have a somewhat substantial project that won't let me add an imagelist
(with images that is) to any form without throwing a null refference
exception when trying to run the following lines of code (added by IDE).

Me.ImageList1.Images.Add(CType(resources.GetObject("resource"),
System.Drawing.Image))


I can create a new project ....add a form ... add an imagelist in exactly
the same fashion....and it works as if should.

Any ideas as to why this project is giving me fits with imagelists?

BTW.....It's written in VB.net

 

[Daniel Moth]

Is there already another ImageList on the form?
Where does ImageList1 get created?
It throws with existing forms in that project; does it throw if you add it
to a *new* form in that project?
Does it throw when you add an ImageList from the toolbar and populate it
(rather than adding a pre-populated one)?
What are the values of each element of that line prior to the exception?
[put a breakpoint on the line and step into]

Cheers
Daniel

1) nope....no other imagelist on form or anywhere in project.
2)I dropped a imagelist control onto form and added images through the
collection editor in the IDE.
3)I does throw if I add new form and add imagelist to it.
5) this is the null object from what I can tell:
resources.GetObject("resource")
it returns :nothing".

4)I'm not sure what you mean by adding from toolbar and populatiung it
(rather than adding pre-populated one)
If I add one with no images added to it, it doesn't throw (if that's what
you mean).

OK, it sounds like it cannot find "resource".

You said you add images; can you try with a single image at a time to see
which one is the culprit?

Also by calling assembly.GetManifestResourceNames you can find out which
resources it *does* know about.

Worst case scenario, add your images as embedded resources to the project
and then manually add them to the ImageList (or other target control)
programmatically

I'm trying to add them programmatically now.

here's what I'm trying (it returns nothing also)
Dim bmp As New
Bitmap([Assembly].GetExecutingAssembly().GetManifestResourceStream("allmidap
sdbreplflexgrid.anchor.bmp"))

I've seen several samples of this that work fine (some of them are loaded on
my machine). But I cannot get them to work for myself for some reason.

8 out of 10 it is a problem with not passing the name correctly (missing a
namespace or folder name).

Have you tried as per previous suggestion to call
assembly.GetManifestResourceNames? This will tell you the exact names you
have to use.

Not without debugging it.... You could go back and add them to the ImageList
and use the getmanifestresourcenames approach to see where it goes wrong...
or try one image at a time to see which one is problematic (different sizes
perhaps).. etc.. debugging it...

Glad you got it working

I did already debug it. It's trying to use "reource" and
"resource1".....neither of which are in the manifest list. there are howver
13 items in the resourcelist. I guess the collection editor isn't smart
enough to keep track of everything?

Thanks again for you quick replies...you've been a great help.

Actually strike the comment about using getmanifestresourcenames when adding
them to the ImageList. The names are actually in the resx file (if you show
all files, the one under the form1.vb). I still don't know why it doesn't
work for you. It does over here, so it must be something to do with the
specific images. What are they (bmps, jpg) and what size?

The point is that the approach that worked for you is the one I personally
prefer and use.
