Windows Forms ImageList ArgumentOutOfRangeException: InvalidArgument=Value of '1' is not valid for 'index'.

Question

Hi all,

I have a Windows Forms application, a form with an ImageList containing 8 images loaded at design time.

The ImageList is used in runtime in this way:

private int IMG_GREEN = 1;
...
pictureBoxStatus.Image = imageList1.Images[IMG_GREEN];
...

It works fine at most computers (hundreds), but it raises exception at only one.

Do you have any idea, where can be a problem?

Damaged the exe file?

Wrong assembly of .NET framework?

Virus?

Thanks

Jiri

Answer 1

hi,

did you try re-installing it?

if it is 1 in hundreds, it is not going to be a coding error.

Not yet, I'am not personally responsible for the deployment, so I'am waiting for response from my colleagues.

Answer 3

Have you done the imageList1.Add("xxxxx") before the

pictureBoxStatus.Image = imageList1.Images[IMG_GREEN];
?

List the full function here if you want.

?

No, the imagelist is filled in design time with eight images.

HI,

Your imageslist is filled at design time / runtime?

At design time.

Answer 7

Hi jirpun,

Any updates from your colleagues? The exception means the index 1 is outside the allowable range of images. Try @Nico's suggestion, reinstall it.

Have a nice day.
