yiweihua2002,
You didn't say if you were using LabVIEW 8.2 or 8.2.1, so I'm not sure if this truely reproduces your behavior.
However, I just ran LabVIEW 8.2.1 and selected the adapter API, and I was able to see all of the items.
There are a few things I'd like you to try:
1) Run the TestStand Version Selector and make version 3.5 active. Even if it is already the active version, this will re-register all of the TestStand components to make sure they are properly working
2) Restart LabVIEW (if you haven't already)
