Statstring Parsing - c++ code

This isn't complete, but I got bored with it, so it's as complete as it's getting without somebody else contributing.  Here it is:

hmm, I guess I should also post the .h file:

Code Select Expand


#ifndef PARSESTATSTRING_H
#define PARSESTATSTRING_H

#include <windows.h>
#include <iostream>
using namespace std;

class ParseStatString
{
public:
   ParseStatString();
   static string GetStatString(char *SS);

};


#endif

  Thanks a ton - now for me to change it to VB

[iago]

lol, no.

It's not terribly complicated code, for the most part.. shouldn't be horribly difficult to translate

[K]

Just as a really picky sidenote, you shouldn't use

Code Select Expand


using namespace std;


in a header file, since it will e(a?)ffect all the source files that include it, which can cause some undesired naming conflicts.  I'll usually write out the fully qualified name (std::string) in the header, and then add using declarations in the source file.

But other than that teeny point, nicely done.

[Banana fanna fo fanna]

Wow...someone actually uses the std c++ string class!?

[K]

Wow...someone actually uses the std c++ string class!?

The real question is why anyone wouldn't use it.  Goodbye dealing with null terminator; goodbye strcmp, strcat, strcpy; goodbye buffer overflows; goodbye possible memory leaks...

[Eibro]

If i'm not mistaken, std::strstream is deprecated. You should use header file sstream instead. std::ostringstream/std::istringstream/std::stringstream should offer the same functionality.

[Banana fanna fo fanna]

K, I know the benefits, but no one uses it.

[Kp]

The real question is why anyone wouldn't use it.

When was the last time you saw a system call that took or returned an std::string?  STL may be nice for intraprocess work, but it can be a nuisance when you're regularly passing things into and out of the OS.

[iago]

We use std::string and strstream in school for assignments, so that's why I use it; a lot of people use is, especially at school.  And Kp is right - but I'm not using any API calls, so life is good.

And K - I've never had a problem with setting that namespace in .h files, but that's the only namespace I ever use.
