Did you think about your question you need to a class for save application settings of your program you need to make it yourself I think you found your answer previous(ini files,xml files and registry) you need to make a class for them then you need to shift your parameters to that class.

I'm not asking for help to invent the wheel, but asking for help to find an article / library that can provide the implemention of the wheel I need.
I rather want to reuse than to remake it myself.

Good idea: develop it and write a good article about.

Thank you for the encouragement

Think I have found the main building block, that satisfies most of my needs:
* Can save to the registry
* Can save to an ini-file
* Can save to an xml-file
And it has a reasonable license requirements:
* You are allowed to include the source code in any product (commercial, shareware, freeware or otherwise) when your product is released in binary form.
* You are allowed to modify the source code in any way you want except you cannot modify the copyright details at the top of each module.
* If you want to distribute source code with your application, then you are only allowed to distribute versions released by the author. This is to maintain a single distribution point for the source code.

All I need now is to create my in-memory configuration-class, and make a thin wrapper around the AppSettings class.

In cmath or math.h, there are only float/double versions.

Why do you need it? If your exponent (or base) is real then you have to use anyway the double version, if both base and exponent are integers then, you know, repeated multiplication does the job.

There's no power function for integers - your best bet is to try something like this:
int ipow(int x, int y)
{
return (int)pow((double)x, (double)y);
}
Doesn't protect against overflow or anything, but does the job for appropriate inputs.

int main(void)
{
const char *buf = "PICK ANY TWO: 10 2 F F";
string name;
ostringstream oss;
istringstream iss(buf);
iss.get(*oss.rdbuf(), ':');
name = oss.str();
return 0;
}

Depends what it's meant to do - if it's meant to display a message on the screen, there are plenty of flaws...

Given the string "PICK ANY TWO: 10 2 F F",
get the token before ':', it's "PICK ANY TWO".
|
|
|
|
|
I'd probably do this:
int main(void)
{
const std::string s("PICK ANY TWO: 10 2 F F");
const string name(s.substr(0, s.find(":"));
return 0;
}
Little bit simpler...

Sure
But when I want to parse the string to 5 parts, as
PICK ANY TWO
10
2
F
F
use stringstream seems more consistent,
I'm not sure if there is any simpler version.
C can do this in a very clear way, can C++:
char name[41] = {0};
int m,n;
char c,d;
int i = sscanf_s(buf, "%[^:]%*c%d %d %c %c",name, _countof(name), &m, &n, &c, 1, &d, 1);
Thanks.

You could use the std::tr1::regex [^] class (that's in from VC2008, I believe). Probably not as simple as sscanf for your case (although I wasn't aware sscanf would parse pseudo-character classes like the [^:] - there's me learnt something new today!).
You're on the cusp of needing something more complex than scanf, for which I guess regex would be as easy as anything else.
Anywhere - here's a regex equivalent for your code (the smiley is a colon followed by an open bracket:
#include <regex>
#include <iostream>
#include <string>
int main(void)
{
std::tr1::regex re("^([^:]*):"
"(\\d+)\\s+(\\d+)\\s+"
"(\\S)\\s+(\\S)$");
std::string s("PICK ANY TWO:10 2 F F");
std::tr1::smatch matches;
if (boost::regex_match(s, matches, re))
{
std::string name = matches[1];
int m = atol(matches.str(2).c_str());
int n = atol(matches.str(3).c_str());
char c = matches.str(4)[0];
char d = matches.str(5)[0];
}
}

Hi,
How can I create a Hidden Directory?
|
|
|
|
|
Call CreateDirectory() to create the directory, then SetFileAttributes() with FILE_ATTRIBUTE_HIDDEN to hide it.
|
|
|
|
|
yes I know! there is a lot of the same question here in www.codeproject.com. But I need a standard API or something to detect the connectivity.
Thank you masters!

You can use InternetGetConnectedState() by including wininet.h and using the following snippet:
#pragma comment(lib,"wininet.lib")
if (InternetGetConnectedState(INTERNET_CONNECTION_LAN | INTERNET_CONNECTION_MODEM,0) == FALSE)
{
}
else
{
}
Cheers!
