SQLBrowseConnect获得MySQL中的所有库名

[「已注销」]

想获取远程主机上MySQL中的所有库名，
CString szInputParam;
szInputParam="DRIVER={MySQL ODBC 5.1 Driver};SERVER=192.168.1.16;Option=3;UID=gelong;PASSWORD=123456;";
m_iRetcode = SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &hSQLEnv);
m_iRetcode = SQLSetEnvAttr(hSQLEnv, SQL_ATTR_ODBC_VERSION, (void *)SQL_OV_ODBC3, 0);
m_iRetcode = SQLAllocHandle(SQL_HANDLE_DBC, hSQLEnv, &hSQLHdbc);
上面几步都成功
m_iRetcode = SQLBrowseConnect(hSQLHdbc, (SQLCHAR *)szInputParam,
SQL_NTS,(SQLCHAR *)szConnStrOut.GetBuffer(MAX_RET_LENGTH)), MAX_RET_LENGTH, &sConnStrOut);

这个SQLBrowseConnect执行不成功，sConnStrOut字符串为空，是不是输入的字符串有问题呢？怎么解决啊？望各位大侠不吝赐教，谢谢啦！！！！！

用QLGetDiagRec去获取错误信息.
eg:
memset(ms_SQLErrMsg, 0, SQL_MAX_MESSAGE_LENGTH * sizeof(SQLCHAR));

SQLCHAR SqlState[6];
SQLINTEGER NativeError;
SQLSMALLINT ssiI, ssiMsgLen;
ssiI = 1;
SQLGetDiagRec(sqlHandlType, sqlHandle, ssiI, SqlState, &NativeError, ms_SQLErrMsg, sizeof(ms_SQLErrMsg), &ssiMsgLen);
