Luciano Resende and me are developing the DAS C++. I started developing it translating the classes from DAS Java to DAS C++. I've already converted most of classes to C++, but the project is not compiling successfully yet and I think it will take some time to. There are many things to be done yet: - As I am not used to work with pointers and references explicity as C++ does, there are some pointers and refereces that are not being used correctly and need to be fixed. - Most of functions' arguments and return are referenced objects. There is necessary to rethink which function argument and return need to be a pointer or a reference. I'm begginer with C++ and I need some advises about it. - To define which argument, return and function will be set as "const" or not. - To define which function will be set as "virtual" or not. - To evaluate which and where to delete the allocated objects. I really need some advises, cause it's being difficult for me to see which is the best to delete these objects. Any volunteer to help with that I'm accepting ; ). But I think I can get by for while. However I'd like invite some volunteers to help me in the implementation of these classes: - ResultSet, ResultSetMetaData, PreparedStatement and CallableStatement: these classes belongs to the JDBC API and they are used a lot in DAS Java. As known, the ODBC API is a procedural API and turns to be very difficult to use a procedural API in a OO application. There is no need to implement these classes as complex as they are in JDBC, only what is really necessary for DAS C++. - DASObject: I initially created this class to set in place of the Java Object class. The DAS Java has some functions that takes the Object class as arguments and as C++ has nothing like it(as far as I know) I created this class. I've not assigned any function to this class(an empty class). Maybe there is another simpler way to substitute the Java Object class, needing some suggestions here too. I will sending right now to Luciano the DAS C++ project, then he may upload it in his sandbox as soon as possible. Adriano Crestani
Some of the issues you describe are common to SDO for C++ (and possiby SCA too - I'm not sufficiently familiar with the code there). I can describe what we did with SDO if that helps. I'm not sure if I'll have time to actually contribute very much but I'll see what I can do. More to follow. Geoff.
