[omniORB] Changing lenght of CORBA::String_var type and setting new value.

[janarbek]

Hi all,

Sorry for sending basic questions,..may be u guys see I am doing progress in CORBA with c++. Ok my question is,...

I want to change lenght of CORB::String_var data variable in a loop and set new const string to my data variable.

What I did was in the below.

My IDL

interface stringTestServer {
void setSize(inout short size);
string returnType();
};

Server code:
data = ( char*) "A";

void stringTestServer_i::setSize(CORBA::Short& size)
{
const char *str ="";
std::string s ="";

for(int i=0;i<size;i++)
{
s+="a";
}
str = s.c_str();
cout<<"Str="<<str<<endl; str varaible changes as loop

data = CORBA::string_dup(str); --> Here is the problem data always prints A
cout<<"Data="<<*data<<endl;
}

char* stringTestServer_i::returnType()
{
return CORBA::string_dup(data);
}

I hope I made myself understand, basically I want to change lenght of data and set new string each time.

data = ( char*) "A";

Firstly, you should never initialise a CORBA::String_var (assuming
that's the type of 'data') to a non-const string. In other words, this
should be:

data = (const char *)"A";

{
const char *str ="";
std::string s ="";
for(int i=0;i<size;i++)
{

}
str = s.c_str();
cout<<"Str="<<str<<endl; str varaible changes as loop
data = CORBA::string_dup(str); --> Here is the problem data always prints A
cout<<"Data="<<*data<<endl;
}

There's nothing obviously wrong with what you're doing. If you're
still having trouble, I'd suggest pasting the entire source file for
your implementation; it's possible there's something else wrong that's
in the missing code.

Cheers,
Jason.
