Occi GetString causing a exception with ntdll.dll oracle 10g and MS 2005

Question

hi,
I am getting an exception with using Visual Studio 2005(VC++8) and occi.h 10g client.
When I run the release version I get an exception in ntdll.dll.
The problem is in the getString(). The field in the oracle table is defined as a varchar2(300).
I am new to oracle occi and need a solution because we cannot migrate to another version of the database.
These are the solutions I have tried:
download patches for MS Visual studio
download patched for oracle 10g client
Check that the charset it correct for std:string
I see that others have had the same problem but no one has a solution. If anyone has a solution please email me because I have searched for days!
Thanks
Sheryl

Thank you for your response, I am new to posting, occi and C++. Can I send you the files.
Sorry didnt read this reply until today.
The email is [email protected].
This environment:
1> windows xp
2> MS Studio 5 VC++8
3> OCCI 10.2.0.3.0 (patch 13)libraries for Microsoft Visual C++ 8
4> I am using the Instant Client
5> I am using /MD Multithreaded DLL
6> Charset is oracle::occi::Environment::createEnvironment ("US7ASCII","AL16UTF16",Environment::DEFAULT);
7> We running the application in release mode and getting this error with a bad memory reference on getString().
I am getting a memory reference error on the getString(4).
This is the code that is causing the error
try
          string istmt ="SELECT FILE_ID,FILES.FTYP_ID,LTRIM(RTRIM(FILEPATH)),LTRIM(RTRIM(FILENAME)),TITLE FROM FILES,FILE_TYPES WHERE FILE_TYPES.EXTN = 'img'AND file_types.ftyp_id = files.ftyp_id AND FILES.HDR_SCAN_DATE IS NULL ORDER BY FILEPATH, FILENAME ";
          ResultSet * set = db->select(istmt);
          if (set == NULL)
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"No file to process occured in : %s ", methodName.c_str());
               return;
          LogT::Get()->log(Logger::LOG_LEVEL_INFO,"Did select in : %s ", methodName.c_str());     
          while (set->next())
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"Doing a set next in : %s ", methodName.c_str());
               if (set->isNull(1) || set->isNull(2) || set->isNull(4) || set->isNull(3))
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"a value is null continue in : %s ", methodName.c_str());
                    continue;
               try {
                    LogT::Get()->log(Logger::LOG_LEVEL_INFO,"About to get string 3 in : %s ", methodName.c_str());
                    std::string test(set->getString(3));
                    fname.assign(test);
                    LogT::Get()->log(Logger::LOG_LEVEL_INFO,"File name: %s in : %s ",fname.c_str(), methodName.c_str());
               } catch (exception ex9) {     
                    LogT::Get()->log(Logger::LOG_LEVEL_ERROR,"Exception in get string msg: occured in : %s ",ex9.what(), methodName.c_str());
                    continue;
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"getting int 1 in : %s ", methodName.c_str());
               fid = set->getInt(1);
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"getting string 4 in : %s ", methodName.c_str());
               fn.assign(set->getString(4));
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"after getting string 4 in : %s ", methodName.c_str());
               //dont append a slash if not need
               size_t pos = fname.find_last_of("\\");
               if(pos != fname.length()-1)
                    fname.append("\\");
               fname.append(fn);
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"adding %s to map in : %s ",fname.c_str(), methodName.c_str());
               fnames.insert (std::pair<unsigned int,std::string>(fid,fname));
//               int ftype = set->getInt(2);
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"got fid:%d, fname:%s fn: %s to map in : %s ",fid,fname.c_str(),fn.c_str(), methodName.c_str());
     catch (SQLException ex)
          LogT::Get()->log(Logger::LOG_LEVEL_ERROR,"Sql Exception code: %d message: %s occured in : %s ",ex.getErrorCode(),ex.getMessage().c_str(), methodName.c_str());
          db->exceptionHandler("SELECT PARAMS",ex.getErrorCode(),ex.getMessage());
          throw;
     catch (exception ex3)
          LogT::Get()->log(Logger::LOG_LEVEL_ERROR,"Exception occured message: %sin : %s ", ex3.what(),methodName.c_str());
          db->exceptionHandler("SELECT PARAMS",1,ex3.what());
          throw;
     catch (...) {
          LogT::Get()->log(Logger::LOG_LEVEL_ERROR,"Error occured in : %s ", methodName.c_str());
This is the code for the select in occi
/* Select statement for oracle occi*/
void * OraDb::select(std::string& sqlStr,std::map<std::string,VALUES,classcomp> & val) {
     string methodName = "OraDb::select";
     ResultSet *selectRset;
     try {
          this->stmt->setSQL(sqlStr);
          this->bind(val);
          selectRset = this->stmt->executeQuery ();
          oracle::occi::Statement::Status res = this->stmt->status();
          while(res != oracle::occi::Statement::RESULT_SET_AVAILABLE) {
               LogT::Get()->log(Logger::LOG_LEVEL_INFO,"the results set isnt ready");
               res = this->stmt->status();
     catch (SQLException ex)
          LogT::Get()->log(Logger::LOG_LEVEL_ERROR,"Sql Error in %s code: %d Message:%s",methodName.c_str(),ex.getErrorCode(),ex.getMessage().c_str());
          //Add error to error log                          
          this->exceptionHandler(methodName,ex.getErrorCode(),ex.getMessage());
          throw;
     catch (exception ex3)
          LogT::Get()->log(Logger::LOG_LEVEL_ERROR,"Error in %s Message:%s",methodName.c_str(),ex3.what());
          this->exceptionHandler(methodName,1,ex3.what());
          //Add error to errorlog
          throw;
return selectRset;
This is the logs I get
