E_UNEXPECTED on iProperty read

[FRFR1426]

I'm trying to read an user defined property and sometimes I've got this exception:

System.Runtime.InteropServices.COMException (0x8000FFFF): Défaillance irrémédiable (Exception de HRESULT : 0x8000FFFF (E_UNEXPECTED))
   à System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
   à Inventor.PropertySets.get_Item(Object Index)

Looks to me you are asking the same question in that thread:

Please clarify if I'm not correct.

Thank you,

Hi Philippe,

No, it's not a duplicate. In fact I've got two errors. One happens on call to Inventor.ApprenticeServerDocument.get_PropertySets() (E_FAIL) and another on call to Inventor.PropertySets.get_Item (E_UNEXPECTED). The first one is very mysterious because it happens when I fetch the property sets (User Defined Properties). I don't understand why this is failing. The file is not corrupted. This happens on my client computer, but I'm not able to reproduce it on my computer.

Without a reproducible sample on our side, it's unlikely we can help you further. If the behavior happens on a specific data on that machine, please provide a code sample along with the data, otherwise you may want to suggest to your customer a reinstall of either Inventor or InventorView if he is just using Apprentice.

Regards,

Philippe.
