I use OracleXE 10g and Visual Studio 2010. I can connect to Oracle from CSE or A5M2 database tool. I also connect to Oracle by code use OleDB. But when I add connection to Server Explorer in Visual Studio 2010 I got ORA-06413 Connction not open error. What is wrong? How can I fix this problem?
I'm using Win7 64
Thanks a lot.
