Can't create Connection to Oracle Database

Question

Hi i'm trying to create a simple connection to my oracle database and my projects compiles, but at the "createConnection" statement an SQLException is thrown.
Well first of all my stats:
Windows XP 32 bit
Visual Studio 2005 (VC++ 8)
Oracle Database 10g Express Edition Release 10.2.0.1.0
OCCI
I have already included the "..\OCI\include" directory to my projects additional include directories, the path to the new OCCI dll's and lib's to my additional library dierctories and i have also included the "oraocci10d.lib" to my additional dependencies for the linker.
Now here is the code i'm trying to run (it's just the code of an OCCI sample modified to my preferences):
1 #include <stdlib.h>
2 #include <occi.h>
3 #include <iostream>
4 using namespace oracle::occi;
5 using namespace std;
6
7 int main () {
8     //create environment and connection
9     string user = "myUser";
10     string pw = "myPW";
11     string db = "localhost:1521/XE";
12     Environment *env = Environment::createEnvironment(Environment::DEFAULT);
13     Connection *conn = env->createConnection(user, pw, db);
14     cout << "Environment and Connection created" << endl;
15
16     //execute a SQL statement
17     Statement *stmt = conn->createStatement();
18     stmt->setSQL("INSERT into FRUITS (fruit, amt) VALUES ('apple', 10)");
19     stmt->executeUpdate();
20     conn->terminateStatement(stmt);
21
22     //terminate environment and connection
23     env->terminateConnection(conn);
24     Environment::terminateEnvironment(env);
25     cout << "Environment and Connection terminated" << endl;
26
27     return 0;
28 }
The code crashes at line 13, where i'm trying to create the connection.
Visual Studio breaks and is giving the information, that an SQLException occured.
I looked for the Error code given by the exception and it's 24960.
Well i've found some threads working around that problem, but nothing worked properly to my problem.
Can anyone help me out of my problem?
Addition: I've already debugged the code and the pointer to the environment is good, so this possible cause of the exception (Null-Pointer) is out!
Thanks for any advice!

Answer 1

Well i've found a post at a similar thread, where somebody told to try to compile and run the project in release mode.
Incredibly it works fine, but only for release mode as i told.
The debug mode is still having the same problem...
If somebody has an idea how to solve this problem please let me know!
Thanks, olf77.
