Hello,everyone. Now I use VS C++ 2005 (with sp1)and OCI that in ORACLE 10g to develop a application.
calling OCIEnvCreate failed when connect the Database. The return value is -1. My Pataner saied, I cannot use OCIErrorGet() to get the error informaintion,becase The Environment isnot initialed.

But I can connect Database by using ORACLE 10g Client in my mathine(Input the same username and password).
Why OCIEnvCreate function return -1?
