  14. In CMyFrame::CanAccept Drop I want to find the category of the part about 
  15. to
  16. be dropped, and want to compare this category with a prestored category. 
  17. How
  18. should I do this? I have tried to access the storage unit through the
  19. dragInfo parameter like this:
  20.  
  21.         ODStorageUnit* dragSU;
  22.         ODValueType partCategory = kODNULL;
  23.  
  24.         for (dragSU = dragInfo->First(ev); dragSU; dragSU =
  25. dragInfo->Next(ev))
  26.         {
  27.                 if(dragSU->Exists(ev, kODPropContents, partCategory, 0))
  28.                 {
  29.                         dragSU->Focus(ev, kODPropContents, 
  30. kODPosUndefined,
  31. kODNULL, 0, ODPosUndefined);
  32.                         partCategory = dragSU->GetType(ev);
  33.                 }
  34.         }
  35.  
  36. But this does not work
