I am new to OCCI and am using VS.NET to access Oracle database. I am having problems with the createConnection call. When I execute the program I get the following error:
An unhandled exception at 0x6087e01e in oracleoccitest.exe: 0xC0000005:Access violation reading location 0xcc005248.

source code:

int _tmain(int argc, _TCHAR* argv[])
{
Environment *env = Environment::createEnvironment(Environment:DEFAULT);
try {
Connection *con =
env->createConnection("TESTUSER","TESTUSER","SERVERIP:1521/DBNAME"); /*Error!*/
env->terminateConnection(con);
} catch ( ... ) {
}
Environment::terminateEnvironment(env);
return 0;
}

project setting:
/Od /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_MBCS" /Gm /EHsc /RTC1 /MD /Fo"Debug/" /Fd"Debug/vc70.pdb" /W3 /nologo /c /Wp64 /ZI /TP

oracle installation:
92010NT_Disk1.zip
OCCI Resources:
%ORACLE_HOME\oci\lib\msvc (no vc71 subdirectory)
%ORACLE_HOME\oci\include
%ORACLE_HOME\oci\samples
VS version:
vc++ 7.1.3091

Any one got a solution??!

Who can file a trouble ticket with Oracle and let me know what they find out?

Hi there. Did you resolve your problem?

I have the same problem, but only with our full application. When I take a small test case, there is no exception - very fustrating.

Any update would be gratefully received!

OCCI 9iR2 is not supported with VC7.1. It is supported only with VC7.0.
OCCI 10g is supported with both VC7.0 and VC7.1.
See http://download-uk.oracle.com/docs/html/B10132_04/toc.htm#CACHEDDD

thank you!

6.1.4 Support for Microsoft Visual C++ 7.1 .NET 2003
Applications developed in Microsoft Visual C++ 7.1 .NET 2003 should use oraocci10.lib and oraocci10.dll. The currently shipped OCCI DLL is built with Microsoft Visual C++ 6.0 and cannot be used from a Microsoft Visual C++ 7.1 .NET 2003 compiled application. This OCCI DLL links with the non-debug version of Microsoft CRT (MSVCR71.DLL). The installed location is ORACLE_BASE\ORACLE_HOME\oci\lib\msvc\vc71.

6.1.5 Support for Debug Version of Microsoft Visual C++ 7.1 .NET 2003
Applications that are linked with MSVCR71D.DLL (debug version of Microsoft C-Runtime) in Microsoft Visual C++ 7.1 .NET 2003 in order to debug memory issues should link with oraocci10d.lib and oraocci10d.dll. The installed location is ORACLE_BASE\ORACLE_HOME\oci\lib\msvc\vc71.
