How to check two IAccessible are Identical at runtime? It seems that there is no method provided by MSAA. I know that
1.we can check multi property of these two IAccessible object， but stirng cmp/string get/role get/role cmp/... may consume lots of time.
2.the simplest way to compare these two object is compare the address, but I failed.
Anyone can show me an example or give me a hint? Thanks very much!
