    How do I programatically get a list of all databases on a known server?
    What I need is to make my code as flexible as possible. I suceeded in (1) listing all the availble SQL Servers in the domain; (2) I was able to create a DSN in ODBC dynamically but wit a hardcoded database as in

    RETCODE retcode;
    LPTSTR szDriver = "SQL Server";

    char szAttributesChar[255];

    // add datasource name if it exixts
    dsn_str = "DSN=" + m_MyProgramaticDSN + "\0";
    LPTSTR lpszMyProgramaticDSN = new TCHAR[dsn_str.GetLength()+1];
    _tcscpy(lpszMyProgramaticDSN, dsn_str);

    server_str = "SERVER=" + m_cmbSQLservername + "\0";
    LPTSTR lpszSQLservername = new TCHAR[server_str.GetLength()+1];
    _tcscpy(lpszSQLservername, server_str);

    LPTSTR lpszDATABASE = "DATABASE=VersaScanMeSQL\0";
    LPTSTR lpszDESCRIPTION = "DESCRIPTION=Dynamically created datasetname\0";

    ...
    ..

    // remove the local datasource name if it exixts
    TCHAR szAttributesRemove[1028];
    TCHAR* szSubStringRemove = &(szAttributesRemove[0]);
    // remove an existing DSN
    BOOL bretcode = SQLConfigDataSource(NULL, ODBC_REMOVE_SYS_DSN, szDriver,
    &(szAttributesRemove[0]) /*szAttributes*/);

    As you can see, the database is hardcoded. If I can figureout a way of programtically getting it, I will be okay and that is what I am looking for.

    Note that I have not yet connected to the database.

    I guess you already know this, but the SQL command for this is "show databases". I don't know if this helps anything?
