[2008] se connecter a une base depuis un programme en C++

bonjour
Il y a deux choses a faire pour connecter la base
Ajouter un assembly qui se trouve /Program Files/Microsoft SQL Server/100/SDK/Assemblies/Microsoft.SqlServer.Types.dll
mettre un code adapté:

namespace SpecificationChecker
{
    using namespace System;
    using namespace System::ComponentModel;
    using namespace System::Collections;
    using namespace System::Windows::Forms;
    using namespace System::Data;
    using namespace System::Drawing;
    using namespace System::IO;
 
    ref class CInterbaseManagerM
    {
    private:
        static SQLHANDLE* sqlenvhandle;    
        static SQLHANDLE* sqlconnectionhandle;
        static SQLHANDLE* sqlstatementhandle;
        static SQLRETURN retcode;
    public:
        CInterbaseManagerM::CInterbaseManagerM();
        CInterbaseManagerM::~CInterbaseManagerM();
        static void CInterbaseManagerM::edit( char* final_err_buff);
        static erc CInterbaseManagerM::ConnectServer(std::wstring wsUserName, std::wstring wsPassword, std::wstring wsHost);
        static List<ElementSemanticM^>^ CInterbaseManagerM::ExecuteSelectRequestAndReadElement(std::wstring wsRequest, unsigned long* dwNbResultFound);
        static List<ElementLinksM^>^ CInterbaseManagerM::ExecuteSelectAndLinkRequest( std::wstring wsRequest, ElementSemanticM^ pEnreg, unsigned long  &dwNbResultFound);
        static erc CInterbaseManagerM::GetWideString(short shIndexField, std::wstring & wsStringValue);
        static List<ElementWork^>^ CInterbaseManagerM::ExecuteSelectRequestAndReadWork(std::wstring wsRequest, unsigned long* dwNbResultFound);
    }; 
};

et la procédure

        if( ErrorCode == INIT_NO_ERROR || ErrorCode == 1)
        {
            if(SQL_SUCCESS!=SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, sqlenvhandle))
            ;
             if(SQL_SUCCESS!=SQLSetEnvAttr(sqlenvhandle,SQL_ATTR_ODBC_VERSION, (SQLPOINTER)SQL_OV_ODBC3, 0)) 
            ;
            if(SQL_SUCCESS!=SQLAllocHandle(SQL_HANDLE_DBC, sqlenvhandle, sqlconnectionhandle))
            ;
            SQLWCHAR retconstring[1024];
            switch(SQLDriverConnect (sqlconnectionhandle, NULL, (SQLWCHAR*)L"DRIVER={SQL Server};SERVER=localhost, 1433;DATABASE=COHERENCE;UID=sa;PWD=Admin-123;", SQL_NTS, retconstring, 1024, NULL,SQL_DRIVER_NOPROMPT))
            {
                case SQL_SUCCESS_WITH_INFO:
                    show_error(SQL_HANDLE_DBC, (const SQLHANDLE*)sqlconnectionhandle);
                    break;
                case SQL_INVALID_HANDLE:
                case SQL_ERROR:
                    show_error(SQL_HANDLE_DBC, (const SQLHANDLE*)sqlconnectionhandle);
                    retcode = -1;
                    break;
                default:
                    break;
            }
            if(retcode == -1)
            ;
             if(SQL_SUCCESS!=SQLAllocHandle(SQL_HANDLE_STMT, sqlconnectionhandle, sqlstatementhandle))
            ;
        }

ca compile alors :il reste a le vérifier à l'exécution.
