I would like to know whats wrong with following JavaScript code -
```
<html>
<script type="text/javascript">
var p = eval('new { "Color":"Red"}');
alert(p.Color);
</script>
</html>
```
It is giving me JavaScript error as -
```
Message: Object doesn't support this action
Line: 4
Char: 1
Code: 0
```
There are several problems with the code;
firstly you're telling the script to create something new, but you're not telling it *what* to create. If you aren't creating a custom object, you are creating an Object object, so you need to tell it that:
```
var p = eval('new Object()');
```
Now that you are creating a new Object object, you can configure the Color property:
```
var p = eval('new Object({"Color":"Red"})');
```

I've built a C application, and when I build it, it shows no errors, but when I run it, it gives me the error "Segmentation Fault: 11".
If it helps, here is the code I am using:
```
#include <stdio.h>
int main(char *argv[]) {
printf("The project path is: ./Projects/%c", argv[1]);
return 0;
}
```
You have a number of problems:
* The signature for `main` is an argument count followed by an array of C strings.
* You should always check the count before using the array.
* The array is of strings so you need `%s` to print them.
This should work:

Let me know if any other information is required.
Thanks in Advance!
There are 2 causes to why this doesn't work:
1. The svg is empty.
Even though you gave it a height and width, I believe that some browsers don't assign it a real size until you actuall add a shape to it. You can get around this by placing an empty rect there:
`<rect x="0" y="0" width="300" height="300" stroke="black" stroke-width="0" fill="none"></rect>`
2. Because of the `pointer-events` property. You can read more [here](http://www.w3.org/TR/SVG/interact.html#PointerEventsProperty). By default, it's value is `visiblePainted`, so I really don't know why Chrome and FF allow the events | [

This is my first time around, so i would appreciate your patience with what might appear as a lame looking question :)
I'm trying to write a function called `do_n` that takes a function object and a number, `n`, as arguments and then call the given function `n` times. Here's the code:
```
def name():
print 'Jack'
def do_n(fo, x):
if x <= 0:
return
print fo
(fo, x-1)
```
When making a function call from within main:
```
do_n(name, 3)
```
I get the following outcome:
```
<function name at 0x01F93AF0>
```

Many thanks in advance
You are neither calling the function, nor are you actually doing the recursive call. Corrected version:
```
def name():
print 'Jack'
def do_n(fo, x):
if x <= 0:
return
fo()
do_n(fo, x - 1)
```
To call a function `n` times, you'd usually use a for loop instead of tail recursion in Python:
```
for dummy in range(10):
name()

I'm trying to write up an example of testing query string parsing when I got stumped on a Unicode issue. In short, the letter "Omega" (Ω) doesn't seem to be decoded correctly.
* Unicode: U+2126
* 3-byte sequence: \xe2\x84\xa6
* URI encoded: %E2%84%A6
So I wrote this test program verify that I could "decode" unicode query strings with URI::Encode.

decodes them into a utf-8 byte string, and neither of them decode the bytestrings as UTF-8 (which is a correct behavior as a generic URI decoding library).
Put it another way, your code basically does:
`is "\N{U+2126}", "\xe2\x84\xa6"` and that will fail, since upon comparison, perl upgrades the latter as a 3-character-length latin-1 strings.
You have to manually decode the input value with `Encode::decode_utf8` after `uri_decode`, or instead compare encoded utf8 byte sequence. | [

Can anyone please tell me the exact difference between `currentTarget` and `target` property in JavaScript events with example and which property is used in which scenario?
Events [bubble](https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Building_blocks/Events#event_bubbling_and_capture) by default. So the difference between the two is:
* `target` is the element that triggered the event (e.g., the user clicked on)
* `currentTarget` is the element that the event listener is attached to. | [

C#/.NET 4.0
I need to parse a string containing a 18-digit number. I also need the substrings at the left and right side.
Example strings:
```
string a = "Frl Camp Gerbesklooster 871687120000000691 OPLDN 2010 H1";
string b = "some text with spaces 123456789012345678 more text";
```
How it should be parsed:
```
string aParsed[0] = "Frl Camp Gerbesklooster";
string aParsed[1] = "871687120000000691";
string aParsed[2] = "OPLDN 2010 H1";
string bParsed[0] = "some text with spaces";
string bParsed[1] = "123456789012345678";
string bParsed[2] = "more text";
```
There is always that 18-digit number in the middle of the string. I'm an absolute newbie to Regex so I don't actually have a try of my | [

own.
What is the best way to do this? Should I use regular expressions?
Thanks.
You can use something like the regex: `(.*)(\d{18})(.*)`.
The key here is to use `{18}` to specify that there must be exactly `18` digits and to capture each part in a group.
```
var parts = Regex.Matches(s, @"(.*)(\d{18})(.*)")
.Cast<Match>()
.SelectMany(m => m.Groups.Cast<Group>().Skip(1).Select(g=>g.Value))
.ToArray();

In my application I am using a simple JavaScript popup and successfully invoking it this way-
```
<a href="javascript:popup('Hello World')>Click Me</a>
```
I was wondering whether it is possible to invoke the same popup on other jQuery events. For instance
```
$("#some_button_id").click( function() {
javascript:popup('Hello World');
});
```
The above method doesn't work. Any other solution?

I am trying to set a BOOL within Xcode and for some reason it is plain refusing to work. Nothing else is setting this bool, just this one instance. My code is below:
.h
```
@interface SuspectsViewController : UIViewController
{
BOOL boolContentChanged;
}
@property (nonatomic) BOOL boolContentChanged;
```
.m
```
@synthesize boolContentChanged;
-(IBAction)buttonPressed:(id)sender
{
boolContentChanged = true;
}
```
I have also tried using self.boolContentChanged but nothing happens either. To try and debug this I used po boolContentChanged and get the following output, the first po is before boolContentChanged = true and the second is after.
```
(lldb) po boolContentChanged
(BOOL) $4 = '\0' <nil>
(lldb) po boolContentChanged
(BOOL) $7 = '\0' <nil>

the $ indicate that it's pointing to a certain address, or is that purely for debugging reference?
Also, is there any reason this would be nil? Surely it doesn't need implicitly setting if it is a bool and not a pointer?
Any advice on this is much appreciated as I can't work it out,

I'm relatively new to python and am starting to work with suffix trees. I can build them, but I'm running into a memory issue when the string gets large. I know that they can be used to work with DNA strings of size 4^10 or 4^12, but whenever I try to implement a method, I end up with a memory issue.

matching strings in a very large string. The search string match size is 16. So, this would look for a string of size 16 within a large string, and then move onto the next string and perform another search. Since I'll be doing a very large number of searches, a suffix tree was suggested.
Many thanks
As others have said already, the data structure you are building is not a suffix tree. However, the **memory issues** stem largely from the fact that your data structure involves a lot of **explicit string copies.** A call like this

substring starting at `i+1`.
If you are still interested in constructing your original data structure (whatever its use may be), a good solution is to use **buffers** instead of string copies. Your algorithm would then look like this:
```
def suffixtree(string):
N = len(string)
for i in xrange(N):
if tree.has_key(string[i]):
tree[string[i]].append(buffer(string,i+1,N))
else:
tree[string[i]]=[buffer(string,i+1,N)]
return tree
```

**Note that this will likely be relevant even if you switch to an actual suffix tree.** A correct suffix tree implementation will not store copies (not even buffers) in the tree edges; however, during tree construction you might need a lot of temporary copies of the strings. Using the `buffer` type for these is a very good idea to avoid putting a heavy burden on the garbage collector for all the unnecessary explicit string | [

I wrote a function to convert the input month parameter to a certain format. such as if I passed 04 to the function and the function will return the "***\_****APR*\_". the function I wrote is like below:
```
function GetEnMonth()
{
param([string] $month)
switch ($month)

}
return [string]$result;
}
```
Then I use below command to execute the function to get the result:
```
$mYear = $today.substring(0,4)
$mMonth =$today.substring(4,2)
$mDate = $today.substring(6,2)
$monthInEn = GetEnMonth $mMonth
```
well, the result is always "\_No\_Result\_", why? below is the exception:
```
**** Exception type : System.Management.Automation.RuntimeException
**** Exception message : You cannot call a method on a null-valued expression.
```
Could anyone give me an answer for this?

I neeed to create multiple versions of my project using configuration just like we do with `#define`, `#if`, `#endif`.
The down side of using these preprocessor directives is that I need to define symbols in almost every file of the project but I want to handle this thing by my build configurations.
I am not even sure if Build Configurations will help me to do this.
What I want is if I create a configuration with name "Development" and other with name "QA", my code would look like:
```
if #Development or if $QA
```
Kindly guide me towards achieving this.
Configuration Manager exist for this reason.

* Name the configuration DEVELOPMENT and apply to all projects
* Select as Active Configuration the DEVELOPMENT configuration (should already be the
active one)
* Go to the properties page of each project requiring `#if DEVELOPMENT`
conditional compile and insert the DEVELOPMENT symbol in first textbox of the BUILD tab

Yes, you can use a Condition element like this:
```
<Directory Id="FooFolder" Name="Foo">
<Component Id="SomeId">
<File Source="..." />
<Condition>Not FOO_FOLDER_ALREADY_EXISTS</Condition>
</Component>
</Directory>

The kind of things that you can use as a condition are explained in the [Conditional Statement Syntax](http://msdn.microsoft.com/en-us/library/windows/desktop/aa368012%28v=vs.85%29.aspx) documentation of windows installer.
In this case, I believe you can set the `FOO_FOLDER_ALREADY_EXISTS` property with a [DirectorySearch](http://wix.sourceforge.net/manual-wix3/wix_xsd_directorysearch.htm) like this:
```
<Property Id="FOO_FOLDER_ALREADY_EXISTS">
<DirectorySearch Id="FooFolderSearch" Path="[FooFolder]" />

search above doesn't work because the `[FooFolder]` property is only resolved during the `CostFinalize` action (see [documentation](http://msdn.microsoft.com/en-us/library/windows/desktop/aa372403%28v=vs.85%29.aspx)).

So, How can I resolve this problem ?
Any help would be Appreciated.
Thanks, Yuvi
Signal interrupts scanf. If you add `perror('scanf')` after scanf output will be:
```
SIGRTMAX 64
SIGRTMIN 34
Command Caller has ticked
Data Caller has ticked
scanf: Interrupted system call
```
If you replace `scanf` with:
```
do {
errno = 0;
scanf("%d", &t);
} while(errno == EINTR);
```
scanf will be retried when it fail with `Interrupted system call`. | [

Were are facing a big problem with string length control in SQL Server 2008.
A brief recap of our system:
* import data in a persistent staging area from `*.txt` file (semicolon as separator), using bulk insert in SQL Server environment;
* in PSA table all columns are `varchar(MAX)`;
* cleaning operations using insert statement based on a select with multiple where conditions.
The problem we deal with is on a single column type and length, in fact in data warehouse level it has to be numeric and its lengths must not exceed 13 digits.
The select is the following:
```

The critical field is `codice_ean_prodotto`.
In fact, it allows to consider also values as `SEAGAT7636490026751,NE20000003039,NE20000002168` which are not numeric and, the first, overlap maximum dimensions.
As result, the insert statement gives back
> String o binary data would be truncated
error and fails the insertion.
Thanks in advance! I look forward your help!!!

Signal interrupts scanf. If you add `perror('scanf')` after scanf output will be:
```
SIGRTMAX 64
SIGRTMIN 34
Command Caller has ticked
Data Caller has ticked
scanf: Interrupted system call
```
If you replace `scanf` with:
```

init_sigaction();
init_time();

}
```
Now I am using some other function, and I want to pause sigaction timer until other function's execution. how can I implemented interrupt for pause?
Thanks,
From the [manual page](http://linux.die.net/man/2/setitimer) of `setitimer`:
> A timer which is set to zero (it\_value is zero or the timer expires and it\_interval is zero) stops.
Call `setitimer` with zero times, and with a valid `old_value` argument to store the current values of the timer, so you can start it again later.
**Edit:**
How about something like this:
```
struct itimerval old_timer;

I have code like:
```
void Foo(int& a, string& b, vector<int>& c) {
... // 30 lines of code are same as another function
... // 10 lines of code to parse and assign value to vector<int>& c
}
void Foo(int& a, string& b, map<string, int>& d) {
... // 30 lines of code are same as another function
... // 10 lines of code to parse and assign value to map<string, int>& d
}
```
Is there any way to avoid repeat that 30 lines of code? Should I use function overloading in this case?
**EDIT:**
What if the code is not easy to separate out? Like:
