Occi::environment createConnection throws exception

Question

Hi there,
I tried connecting to my Oracle 11g database in debug mode but was unsuccessful. I am developing an ActiveX plugin using Visual Studio 2008. I downloaded OCCI 11.1.0.6.0 and instant client 11.2.0.1.0, extracted the the lib and dll files to my project directory, included the header files as part of my project include directory. Release mode works fine but it's debug that I am having issues with. When I link against oraocci11d.lib in debug mode, it gives me the error "error PRJ0050: Failed to register output. Please ensure you have the appropriate permissions to modify the registry." So then I linked against oraocci11.lib and was able to build successfully. However, I get the following error:
try
          env = Environment::createEnvironment(Environment::DEFAULT);
          conn = env->createConnection("SYSTEM", "pwd", "remoteserver:1521/TEST"); //fails here
env->terminateConnection(conn);
          Environment::terminateEnvironment(env);
catch (SQLException& e)
          std::cout<<e.what();
First-chance exception at 0x7c812afb in iexplore.exe: Microsoft C++ exception: oracle::occi::SQLException at memory location 0x0013a748..
First-chance exception at 0x7c812afb in iexplore.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000..
I see that others are having slightly different issues with Debug mode but I did not see a resolution for any of them. Any help would be much appreciated!

Make sure you include th directory that contains all the necessary header files in your project. It should be in your installed oracle directory (eg. d:\app\oracle\product\11.2.0\dbhome_1\OCI\include) so point to that in Project Properties->C/C++->General->Additional Include Directories. Then link it to oraocci11d.lib under Project Properties->Linker->Input->Additional Dependencies. Also include the following DLLs oraociei11.dll, oraocci11d.dll, oraocci11.dll, orannzsbb11.dll in your debug and release directories.
