Hi ..
What is wrong with this code ?
set<string> nk ;
bitset<3> bs1(string("100"));
nk.insert(bs1.to_string());
error: no matching function for call to `std::bitset<3u::to_string()'
why?!
I am writing a macro in Excel where I need to get a substring from a String.
Its like this.
~/tester/test/hai/bye
~/stack/overflow/hai/bye
In the above cases I need to take the String tester from the first one and stack from the second one.I tried using the Instr but its not useful.Can anyone help this?
I am using the following regex:
(public|private +)?function +([a-zA-Z_$][0-9a-zA-Z_$]*) *\\(([0-9a-zA-Z_$, ]*)\\) *{(.*)}
To match the following string:
public function messenger(text){
sendMsg(text);
}
private function sendMsg(text){
alert(text);
}
(There is no line breaks in the string, they are converted to whitespaces before the regex runs)
I wanted it to capture both functions, but it is capturing:
$1: ""
$2: "messenger"
$3: "text"
$4: " sendMsg(text); } private function sendMsg(text){ alert(text); "
By the way, I am using Javascript.
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,

how to convert a HTML string to a plain text in iphone dev. Is there any in built functions which does it ?
I am actually downloading a html string from web and showing it in the UIwebview and i am giving the user a edit option so that the html needs to converted to tet so that user can edit
Thanks...
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');
While decoding,I am getting NSData bytes by decoding a string.I am converting NSData bytes as string then I am getting the following out put.
-(void)decodeAction:(NSString*)str
{
NSData *data=[NSData base64DataFromString:str];
NSString *stt=[NSString stringWithFormat:@"%@",data];
printf("\n stt %s",[stt UTF8String]);
}

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.
Hello everybody
I am trying to exclude a certain string from a file search.
Suppose I have a list of files: file_Michael.txt, file_Thomas.txt, file_Anne.txt.
I want to be able and write something like
ls *<and not Thomas>.txt
to give me file_Michael.txt and file_Anne.txt, but not file_Thomas.txt.
The reverse is easy:
ls *Thomas.txt
Doing it with a single character is also easy:
ls *[^s].txt
But how to do it with a string?
Sebastian
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?
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
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!
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?
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 have an ASP app that has a string array as such (there are much more than this):
7.5.0.17 Date: 05_03_10
7.5.0.18 Date: 05_03_10
7.5.0.19 Date: 05_04_10
7.5.0.2 Date: 02_19_10
7.5.0.20 Date: 05_06_10
7.5.0.3 Date: 02_26_10
7.5.0.4 Date: 03_02_10
7.5.0.5 Date: 03_08_10
7.5.0.6 Date: 03_12_10
7.5.0.7 Date: 03_19_10
7.5.0.8 Date: 03_25_10
7.5.0.9 Date: 03_26_10
7.5.1.0 Date: 05_06_10
How do I go about sorting these string by version descending?
Hi everyone,
can I convert a string to a html object?
like:
string s = '<div id="myDiv"></div>';
var htmlObject = s.toHtmlObject;
so that i can later on get it by id and do some changing in its style
var ho = document.getElementById("myDiv").style.marginTop = something;
Thanx a million in advance,

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);
I am trying to achieve below output using regex but not able to, can someone please correct the regex -
input string :
data-placeholder=""[Refer" to "Conditions To Entry Of The Confirmation Order" and "Conditions To Effective Date" sections]"
output string :
data-placeholder="[Refer to Conditions To Entry Of The Confirmation Order and Conditions To Effective Date sections]"
regex tried
\s*"\s*([^ "]+)"\s*(?=["])
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)
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.
If I have the following plain string, how do I divide it into an array of three elements?
{["a","English"],["b","US"],["c","Chinese"]}
["a","English"],["b","US"],["c","Chinese"]
This problem is related to JSON string parsing, so I wonder if there is any API to faciliate the conversion.
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?
I have to following entity object
@Entity
public class Foobar {
...
private List<String> uuids;
...
}
Now I'd like to make a criteria query which would fetch all Foobar pojos whose uuids list contains the string "abc123", I'm just not sure how to make the appropriate criterion.
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.
