When I look at some of my old code I got confused. The code is a bit long so I have to paste part of it
only.



CArray<CVertex*, CVertex* &> setOfVertex;

//CVertex is an object contains...

Use a tool called GLFont under ortho view you can output text like

glFontBegin(&font);
glScalef(8.0, 8.0, 8.0);
glTranslatef(30, 30, 0);
glFontTextOut("Test", 5, 5, 0);
glFontEnd();...

Sorry i didn't post the full code only because it involve too much other classes, I will try to make a compilable short version here: 3 files, Command.h, Command.cpp, test.cpp

#ifndef...

I kind figure out where is the problem, cause I wrote a copy constructor in Command class
if I comment this function out, everything in peace

Command::Command(const Command& c){ ...

I define a class which hold some variables first:

class Command{
string cHandle;
int numPara;
vector<int> cPara;
public:
Command();
Command(string ucData);
...

Thanks for suggestion, the problem is I have to initialize some variables in the
constructor of util so I am not sure if util::Show will work.

sorry I kind of simplify it too much, the Show(char *s) method is actually part of a
util class

class util{
public:
...
void Show(char* s);
}

I actually simplify the code to put here, the str indeed contains something before I
add s into it. So in the scenario u mentioned, the code will only output a "g", follow
by blank space.

btw I...

in one file I define

void Show(char* s){
string str =" ";
str+=s;
cout<<str<<endl;
}


then in main I call it by

Thanks, actually i thought I used #ifndef so this would not be included more than
once.
for the do( ), i just use it to simplify code, more like doSomething( )

Simplify my problem I put a short version of code here,
first header file:

namespace xxx{
class util{
public:
static int MAX_PATH ;
util();
static...

Thanks a lot, I always misplace the const keyword.

Potion of my code:

class UserCommand{
string cHandle; //definition of command
int numPara;
vector<int> cPara; //parameter of command
public:
UserCommand(string ucData);
//copy...

Pretty neat solution, thanks.
Here is a Tokenizer class from Codeproject, which can tokenize string separated by
different chars like space, coma, predefined char group etc.


//Tokenizer.h
...

if the token is separated by character like ':' or '|' how can you use sstream to tokenize it?

I use gcc version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)
still i got segmentation error by running your code, never used oss before so I am wondering it might
be the incrementation is over limit.

Dieter your code can't be compiled by me so I use:

std::stringstream my_stringstream;
my_stringstream << in;
string msg = my_stringstream.str();
string msg2=...

sorry i am dumb, figured it out. BTW how to delete one's own post?

f2.c_ptr()->x
f1->c_ptr()->x


Thanks for the reply, I mean when you declare
ref<Foobar> *f1 = new ref<Foobar>;
you can't...

Thanks for the great question and reply. One thing confused me here is, when you do
ref<Foobar> f2;
f2 is a reference of Foobar object? Or say it is a Foobar's reference, then how can I
access...

Indeed it's difficult for me to understand why, but it truely works. Guess in practice i will follow the
first two ways as they are much more clear.
Many thanks for the help!

write it this way and it works, but when I write function body of overload << out of class declaration
then I get error.

#include <iostream>
using namespace std;

template <typename T, int...

Thanks a lot for the help! That solves my problem.
One more question (sorry i am messed by template), in case I don't have public interface and will access _data[] directly, then I will define <<...

Hi, anyone can tell me what's wrong with my code? the only part has problem is the function overload << operator, any help is welcome.

#include <iostream>
using namespace std;

template...
