Will try that tonight.

Here is my code:

[code]
void ODBCDatabase::uc_to_str_cpy(SQLWCHAR *dest, const std::wstring &src)
{
const wchar_t *temp = src.c_str();
while( *dest )
{
*dest++;
}
while( *temp )
{
*dest = *temp;
*dest++;
*temp++;
}
*dest++ = 0;
*dest = 0;
}

int ODBCDatabase::Connect(std::wstring selectedDSN,
std::vector<std::wstring> &errorMsg)
{
int result = 0, bufferSize = 1024;
std::vector<SQLWCHAR *> errorMessage;
SQLWCHAR connectStrIn[sizeof(SQLWCHAR) * 255], driver[1024],
dsn[1024], dbType[1024;
SQLSMALLINT OutConnStrLen;
SQLRETURN ret;
SQLUSMALLINT options;
m_connectString = new SQLWCHAR[sizeof(SQLWCHAR) * 1024];
memset( dsn, 0, sizeof( dsn ) );
memset( connectStrIn, 0, sizeof( connectStrIn ) );
memset( driver, 0, sizeof( driver ) );
uc_to_str_cpy( dsn, selectedDSN.c_str() );
ret = SQLAllocHandle( SQL_HANDLE_ENV, SQL_NULL_HENV, &m_env );
if( ret == SQL_SUCCESS || ret == SQL_SUCCESS_WITH_INFO )
{
ret = SQLSetEnvAttr( m_env, SQL_ATTR_ODBC_VERSION, (SQLPOINTER)
SQL_OV_ODBC3, SQL_IS_INTEGER );
if( ret == SQL_SUCCESS || ret == SQL_SUCCESS_WITH_INFO )
{
ret = SQLAllocHandle( SQL_HANDLE_DBC, m_env, &m_hdbc );
if( ret == SQL_SUCCESS || ret == SQL_SUCCESS_WITH_INFO )
{
if( !GetDriverForDSN( dsn, driver, errorMsg ) )
{
uc_to_str_cpy( connectStrIn, L"DSN=" );
uc_to_str_cpy( connectStrIn, selectedDSN.c_str() );
uc_to_str_cpy( connectStrIn, L";Driver=" );
copy_uc_to_uc( connectStrIn, driver );
SQLSetConnectAttr( m_hdbc, SQL_LOGIN_TIMEOUT, (SQLPOINTER)5, 0 );
options = m_ask ? SQL_DRIVER_COMPLETE_REQUIRED : SQL_DRIVER_COMPLETE;
ret = SQLDriverConnect( m_hdbc, m_handle, connectStrIn, SQL_NTS,
m_connectString, 1024, &OutConnStrLen, options );
// More code dealing with errors or successful connection.
}
[/code]

The code above correctly works on Windows and unixODBC connecting to
the MySQL server.

Thank you.
