What is wrong with this code ?
set<string> nk ;

nk.insert(bs1.to_string());
error: no matching function for call to `std::bitset<3u::to_string()'
why?!

" WHERE linieName LIKE 'lin%';";
Hi,
Is there a way to query a JSON (String) for a specific item?
ie:
String jSon = "{\"a\":{\"b\":27472483,\"c\":\"123\"}}";
such that:
Int32 bob = (Int32)getFromJSON("a.b", jSon);
// bob == 27472483
Thank you,

HI All,
I've been using the basic split for a while - where I just parse out a string into an array based on a simple token like " " or ",".
So of course a customer tries this: \\.br\ which fails miserably.
I need to parse to an array of lines. The string for example looks like this:
"LINE 1\\.br\\LINE 2\\.br\\LINE 3\\.br\\LINE 4\\.br\\"
and this fails with java.util.regex.PatternSyntaxException: Unexpected internal error.
Any ideas?

Hi,
I need a regex expression (PCRE) to match a integer number inside a string, being the string like : image89.jpg
I've tried many options without success.
I'm using preg_replace() by the way
My last attempt :
preg_replace('(\d+)', '$1', 'image89.jpg');
Hello
If I have a method like this:
public static String convertDateTimeToString(DateTime dt) {
return dt.getDate() + " " + dt.getTime();
}
Which takes a Datetime object of my own which contains a Java.sql.date and a Java.sql.time, what is the best way of reversing the process so that I can substring a Java.sql.date and a Java.sql.time from a string?
Or if DateTime dt is a JodaTime DateTime object?
If this can be done without reference to Java.util.date.
Thanks
Mr Morgan.
I have the following:
LPSTR email // Has data in it already
LPSTR index=strchr(email,'@');
Now I want to Insert into a new string:
LPSTR username
the part of "email" from the beginning of the string to "index".
For example:
email="[email protected]"
so username="roel" .
Is there a function to do it quick or do I need to build one?
Roel

We know that string is a reference type , so we have
string s="God is great!";
but on the same note if i declare class say Employee which is a reference type so why below piece of code does not work ?
Employee e = "Saurabh";
2- How do we actually determine if a type is a reference type or value type?
Instead of adding each item one by one to the ListBox destinationList from the string array m_List like this:
foreach (object name in m_List)
{
destinationList.Items.Add((string)name);
}
Is there any better way I can do it?
I don't want to bind the data to the destinationList since I want to delete some entries from the ListBox later on.
I am trying to achieve below output using regex but not able to, can someone please correct the regex -
input string :

regex tried
\s*"\s*([^ "]+)"\s*(?=["])
Hey guys,
I am using heroku for a RoR application and am trying to manually set the length of a string column and am having trouble.
I tried making a migration along the lines of
change_column :posts, :content, :string, :length => 10000
I assumed this would work but no such luck, anyone have some pointers?
Thanks!

In my C++ program I want to parse a small piece of XML, insert some nodes, then extract the new XML (preferably as a std::string)
RapidXML (http://rapidxml.sourceforge.net/) has been recommended to me, but I can't see how to retrieve the XML back as a text string.
(I could iterate over the nodes and attributes and build it myself, but surely there's a build in function that I am missing)
Thank you
Hello All-
In C# how can I search through a Folder and its Subfolders to find files that match a string value. My string value could be "ABC123" and a matching file might be ABC123_200522.tif. Can an Array collect these? Thanks in advance.

How do I go about sorting these string by version descending?
I have an std::string containing a command to be executed with execv, what is the best "C++" way to convert it to the "char *argv[]" that is required by the second parameter of execv()?
To clarify:
std::string cmd = "mycommand arg1 arg2";
char *cmd_argv[];
StrToArgv(cmd, cmd_argv); // how do I write this function?
execv(cmd_argv[0], cmd_argv);
ok i have this program working using c-strings. I am wondering if it is possible to read in blocks of unformatted text to a std::string? I toyed arround with if >> but this reads in line by line. I've been breaking my code and banging my head against the wall trying to use std::string, so I thought it was time to enlist the experts. Here's a working program you need to supply a file "a.txt" with some content to make it run.
i tried to fool around with:
in.read (const_cast<char *>(memblock.c_str()), read_size);
but it was acting odd. I had to do std::cout << memblock.c_str() to get it to print. and memblock.clear() did not clear out the string.
anyway, if you can think of a way to use STL I would greatly appreciate it.
Here's my program using c-strings
// What this program does now: copies a file to a new location byte by byte
// What this program is going to do: get small blocks of a file and encrypt them
#include <fstream>
#include <iostream>
#include <string>
int main (int argc, char * argv[])
{
int read_size = 16;
int infile_size;
std::ifstream in;
std::ofstream out;
char * memblock;
int completed = 0;
memblock = new char [read_size];
in.open ("a.txt", std::ios::in | std::ios::binary | std::ios::ate);
if (in.is_open())
infile_size = in.tellg();
out.open("b.txt", std::ios::out | std::ios::trunc | std::ios::binary);
in.seekg (0, std::ios::beg);// get to beginning of file
while(!in.eof())
{
completed = completed + read_size;
if(completed < infile_size)
{
in.read (memblock, read_size);
out.write (memblock, read_size);
} // end if
else // last run
{
delete[] memblock;
memblock = new char [infile_size % read_size];
in.read (memblock, infile_size % read_size + 1);
out.write (memblock, infile_size % read_size );
} // end else
} // end while
} // main
if you see anything that would make this code better please feel free to let me know.
Given a string s, what is the fastest method to generate a set of all its unique substrings?
Example: for str = "aba" we would get substrs={"a", "b", "ab", "ba", "aba"}.
The naive algorithm would be to traverse the entire string generating substrings in length 1..n in each iteration, yielding an O(n^2) upper bound.
Is a better bound possible?
(this is technically homework, so pointers-only are welcome as well)
Does anyone know of a program, a utility, or some programmatic library, preferably for Linux, that takes an unformatted SQL string and pretty prints it?
For example I would like the following
select * from users where name = 'Paul'
be changed to something like this
select *
from users
where
name = 'Paul'
The exact formatting is not important.
I just need something to take a large SQL string and break it up into something more readable.
I have the following list:
[('Steve Buscemi', 'Mr. Pink'), ('Chris Penn', 'Nice Guy Eddie'), ...]
I need to convert it to a string in the following format:
"(Steve Buscemi, Mr. Pink), (Chris Penn, Nice Guy Eddit), ..."
I tried doing
str = ', '.join(item for item in items)
but run into the following error:
TypeError: sequence item 0: expected string, tuple found
How would I do the above formatting?
In Java, is there a simple method to convert the format of a given string? For example, I have the string "test22". I'd like the binary value and hex value. As well as possibly the ascii values of each character?
