[gme-users] Passing user data in for events.

[Daniel Waddington]

Hi Zoli,

I check the variant at the client side before SendEvent by checking  
CurrentAssociation; it seems to set up fine.  On the receiver (GME)  
side, the object raising the event in objectEventPerformed is  
definitely the "Root Folder" object, but VARIANT v is always empty.   
I checked the associated value with f->getFolderI()- 
 >get_CurrentAssociation(&var), but this is also empty.

Any ideas how I can proceed? I wonder if it is some .NET COM wrapper  
thing that is screwing something up??

Thanks,
Daniel.
