OCI and ORA-12154

Today, we find a problem that ORA-12154: TNS:could not resolve the connect identifier specified. i think many people meet the problem. but today we find the proble is caused by oci.dll. So i record here.it's very difference. because some oci.dll can't parse  parenthesis. if you meet the proble, you can use new oci or change your path :),those two ways will be ok !
This is caused by the path,we test as follow
C:\Program Files (x86)\   error
C:\test\trunk             right
for some oci.dll it not support the parenthesis.
