Catastrophic Failure when adding ClientNodeResource

[basautomationservices]

Hi all,

I'm running into a problem with an addin I am developing. I'm trying to override the icon of an assembly browser folder, for this I'm adding a ClientNodeResource. I have an image (bmp/icon both failed) that I want to use as the icon of the folder. 

For testing purposed I am running the code from a forms application that hooks into Inventor. 

This is the code I am using to add the resource.

            var panes = assembly.BrowserPanes;            
            var clientNodeResources = panes.ClientNodeResources;
            var resourceId = "TestResource";
            var bmp = Properties.Resources.duplicate_bmp;
            var pictureDisp = PictureDispConverter.ToIPictureDisp(bmp);
            ClientNodeResource clientNodeResource;
            try
            {
                clientNodeResource = clientNodeResources.ItemById(resourceId, 1);
            }
            catch (Exception ex)
            {
                clientNodeResource = clientNodeResources.Add(resourceId, 1, pictureDisp);
            }

I'm using the following class to convert from bmp/icon to IPictureDisp. I have a feeling theres something wrong with the conversion. I can't find the LoadPicture(path) method that I see in examples.

Does anybody know why the Catastrophic Failure error is being thrown?

                }
            }
        }

        {

            return OleCreatePictureIndirect(pictIcon, ref iPictureDispGuid, true);
        }

Hello

No solution, just some thoughts.

What's the size of the bmp? Only 16x16pixel is valid.

A bitmap should be loadable from file with the line (VB.Net) below. Just to test if there's something wrong with your resource.

Dim oBMP As New Bitmap(sFullFileName as String)

Thanks for the reply Krieg. It loads just fine.

Bmp is not 16x16. Will try out resized bmp to 16x16 when i get back.

Edit: The problem was the ClientID. When running the code as an addin and providing the correct AddInClientID then the image is loaded. The problem I have now is that the transparent background of the image is not working.. First it made it white, now it's loading the background as black.

will open a new topic for this.
