I recently converted a solution from vs 2003 to 2005. On the main form i use a couple of imagelists.

On every imagelist i use i get an exception on the designer generated code.

Example:

Me.IL_Treeview.ImageStream = CType(resources.GetObject("IL_Treeview.ImageStream"), System.Windows.Forms.ImageListStreamer)
Me.IL_Treeview.TransparentColor = System.Drawing.Color.Transparent
Me.IL_Treeview.Images.SetKeyName(0, "page.png")
Me.IL_Treeview.Images.SetKeyName(1, "bricks.png")
Me.IL_Treeview.Images.SetKeyName(2, "brick.png")
Me.IL_Treeview.Images.SetKeyName(3, "cog.png")
Me.IL_Treeview.Images.SetKeyName(4, "arrow_back.png")
Me.IL_Treeview.Images.SetKeyName(5, "info.png")

in this imagelist the exception is raisedon the row:
Me.IL_Treeview.Images.SetKeyName(4, "arrow_back.png")

System.IndexOutOfRangeException was unhandled
Message="Index was outside the bounds of the array."
Source="System.Windows.Forms"
StackTrace:

What can i do to resolve this issue?

Hi Jonny,

The only thing that comes to my mind would be to verify that the ImageStream that you are loading as a resource does indeed have 6 images in it.

Can you add the following code before you start setting the ImageKeys?

MsgBox(Me.IL_Treeview.Images.Count.ToString())

If the number is indeed 6, then there is a bug in the ImageList or ImageListStreamer class; otherwise your resource is missing some images.

Hope this helps,

It counts 4. I'm not using a resource file and the solution worked (before the conversion) in VS 2003. Does anybody know at what point are the images loadedinto the solution?

The following line is loading the resources that are specific to the imagelist:

Me.IL_Treeview.ImageStream = CType(resources.GetObject("IL_Treeview.ImageStream"), System.Windows.Forms.ImageListStreamer)

Can you do a "Find References" on "resources" and paste the code where it is declared and initialized?

Best Regards,

It's declared in the same form:

Dim resources As System.ComponentModel.ComponentResourceManager = New System.ComponentModel.ComponentResourceManager(GetType(FRM_Hoofdscherm)) - C:\Development\JZL_JTool\FRM_Hoofdscherm.vb(206, 13)

It looks like the resource is embedded into the same assembly, but I don't knowexactly how to verify that assumption.I'll ask someone from the WinForms team to follow up with you.

Best Regards, Abel.

Can you list the contents of the resx file that contains the imagelist? You should be able to open the resx file for FRM_Hoofdscherm and see anxml tag for IL_Treeview.ImageStream.

If you comment out the lines that cause the exception and the designer loads, can you edit the imagelist to see if all 6 images were loaded?

Also, when you run the app, do you see all six images?

Imoved the thread to winforms designer, which is a more appropriate place.

if i skip the lines in debug mode, the application runs normally, and all images are displayed.

I'm not sure what to find in the resx file?

It is localization bug.
It happens because when you run appplication, it reads localized resx file, which doesn't contain some images. The solution is to add this images to the localized version of resx file of the form.

Hello,

I got the same error and i searched everywhere to fix that problem but i could not find any information to fix this problem. An finally i found the solution on my own. now here is the solution;

The solution is addingimagesin to the imagelist by your own

first of all add all imagesthat you are going touse for imagelist in to your projectsResources folder. Then in to the form_load prosedure

this.ımageList1.Images.Add(Your_Name_Sapce.Properties.Resources.Image1); //add this line as much as you are going to add in to your imagelist

this.ımageList1.Images.Add(Your_Name_Sapce.Properties.Resources.Image2);

for each image, add a line like below to declare the index of files.

this.mageList1.Images.SetKeyName(0, "image1");

this.mageList1.Images.SetKeyName(1, "image2");

That is all

Do not forget to edit Your_Name_Space, Image1 adn Image2 as your needs

I hope it would help you.

Hi,

Look into the References of your Project.

If you have a System.Windows.Forms Version 1.x reference, remove it and add a reference to System.Windows.Forms Version 2.0.0.0.

Seems to be problem when upgrading from Visual Studio 2003 to 2005...

That worked for me.

Best regards,

Tony

Hi all

I have the same problem.

I am workin on a software developped in 2005, so it s either VS2003 or VS2005 (language C#). I upgraded it to 2008.

It is always the same exception on the main form where I am using the imagelists. One of them has 13 images, but it keeps reading only 11.

I get the following exception on the designer generated code.

System.IndexOutOfRangeException was unhandled

Message="Index was outside the bounds of the array."

Source="System.Windows.Forms"

I have added int toto=this.imActions.Images.Count; it gives me the value 11 and not 13.

I also tried to remove the existed reference System.Windows.Forms with the one of version 2.0.0.0 but it didn’t work as well

Please help

My friend Kelvin told me:

I also meet the same problem, but I soloved it just now.

Firstly, it's a Visual Studio C#'s bug. The releation between Form.cs and Form.resx was disturbed. I found a easy way to fix it:

1. Change the Form.cs to another name, press 'F5', you can run.
2. Change the name back, press 'F5' again, it fixed.

The reason is when you change the form name, VSS re-associated the resx file automaticlly.

Hello all,

When your Form is set to Localizable=true it could be the problem like Synapse has already written.

If you have no language specific images, the best way is to delete the complete ImageStream from these localized Resource Files (the pictures of Default language will be taken).

On my side I added in an user specific language a picture and afterwards in the default language two pictures at that time the catastrophe begun... :-)

best regards,
Peter
