    string
    PrinterI::getConfiguration(const Ice::Current&)
    {
        return "Hello";
    }
    

    The above is probably close to what you want. I strongly recommend that you read the relevant C++ mapping chapters in the documentation, study the file system example in the doc, and have a good look at the various demos in the distribution. These will answer you questions.

    Cheers,

    Michi.

    thanks

    ok, thanks, but my problem is that: the server and the client must send and get string. I must build for the client the Ice object and the proxy this is my problem. I must build a client but not pure client, the client is a server too.

    thanks.

    Hi,

    I would recommend to check the callback demo from your Ice distribution (located in the demo/Ice/callback directory). I believe it does what you're looking for. Let us know if you still have any questions after checking out this demo.

    Cheers,
    Benoit.

    that's all, work well now.

    But I have another problem, I must use the MFC, how I can to make this:

    ...........
    ......
    string st;
    PrinterPrx printer = PrinterPrx::checkedCast(base);
    if (!printer)
    throw "Invalid proxy";
    st=printer->getGeneral(); //get ther string of the server

    AfxMessageBox(CString(st)); //the problem is here
    ..............

    not possible converter std::string to CString

    st get the string of the server, I must display the string in a messaggebox
    how can I to make this???

    I'm sorry, but we cannot answer questions that are not specific to Ice, such as on general C++ programming or Microsoft class libraries.

    I suggest to check out the CString documentation and the STL reference. Before posting a question here, you should also make a reasonable effort to find the answer in the manual and the demos that ship with Ice.

    I haven't tried this, but something like the following should work:
    ::std::string ss = "Hello";
    CString cs(ss.c_str());
    // use cs...
    

    Cheers,

    Michi.
