[blade]

hello. I use IceE and C++. I have this problem: the client can to send a string to the server (this work well), and the client can to ask a string to the server and the server must send it to the client, how can make this?

the slice is:

module Configuration {
interface Printer{
void setConfiguration(string s);
string getConfiguration();
};
};


help me, please!
thanks

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,

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,

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???
this not a problem of ice, I know this, but I must to make this!

thanks

Sorry for my english, I not speak well in english!

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...

Michi.
