Thumbnails from BOM

[pavol_krasnansky]

Hi
I created Inventor Plug-in (in the Attachment). Plug-in loads BOM in an assembly and it writes in to the table / datgridview. Loading thumbnail of models does't work correct. Some thumbnails are lost (screenshot below). I don't know why. Do samebody know where the problem is?
Thank you

Hello

This could be a known error getting thumbnail. Replace your line

oThumbnail = doc.Thumbnail

with

Do
  oThumbnail = doc.Thumbnail
Loop While oThumbnail.Handle<0

Thank you very much! It works. But I don't know why 🙂

Hello

As stated in this Blogpost, sometimes the returned IPictureDisp.Handle is negative. This will cause the error when trying to convert to image.
