Hi all, would the following Jquery selector get all of the 4th td elements of all the tables on the current page, and return their text as an array?:
var isbn = $.makeArray($("table tr td:nth-child(4)").text());
I notice my query doesn't behave correctly if one of the like variables is empty:
SELECT name
FROM employee
WHERE name LIKE '%a%'
AND color LIKE '%A%'
AND city LIKE '%b%'
AND country LIKE '%B%'
AND sport LIKE '%c%'
AND hobby LIKE '%C%'
Now when a and A are not empty it works but when a, A and c are not empty the c part is not excuted so it seems?
How can I fix this?
Hi:
My program uses sockets for inter-process communication. There is one server listening on a socket port(B) on localhost waiting for a list of TCP clients to connect. And on the other end of the server is another a socket(A) that sends out data to internet. The server is designed to take everything the TCP clients send him and forward to a server on the internet. My question is if two of the TCP clients happened to send data at the same time, is this going to be a problem for the server's outgoing socket(A)?
Thanks
In R, what is the most efficient way to count the length between 2 values. for example, i have vector x , which are all randomly choose from 1 to 100, how can i find out the length between the first"2" and first"40",
x=(1,2,3,4,5,6,7,40,1,2,3,21,4,1,23,4,43,23,4,12,3,43,5,36,3,45,12,31,3,4,23,41,23,5,53,45,3,7,6,36)
for this vector, the answer should be 5 and 6
Is there an ability to import fixed width file to oracle?
Preferably through .net(c#) for catching errors during import and showing them to user.
P.S. File has 5 types of rows. For example 1 row has 5 columns, 2-nd has 50 columns.
To clearly separate the Controller and View layers, I do not longer want to pass full objects to my views. Instead I want to pass only arrays and objects that contain the data but do not have any methods. Otherwise a view script would be able to delete Doctrine records or traverse in the object tree to data that was not intended for the view.
Why does x alerts undefined for iframe but works for embed. I'm grabbing the iframe or embed code from a textarea
<iframe src="http://www.youtube.com/embed/9kiWvkj2ldWiU?hd=1"></iframe>
var textarea = $('#embedModal textarea'),
textareaValue = textarea.val(),
$embed = $($(textareaValue).find('iframe')),
x = $embed.attr('src');
alert(x); //alerts undefined for iframe
If you change find('iframe') to find('embed') and you try with the below embed code. then i'm able to get the value of src, but with iframe i get undefined. Seems strange.

How to acces each element in macro if the definition is like MACRO(name, seq) and the code is like:
MACRO("TheName",
(Elem1)
(Elem2)
(Elem3)
)
I want to generate the next code:
MACRO("TheName",
ELEMMACRO(Elem1)
ELEMMACRO(Elem2)
ELEMMACRO(Elem3)
)
Or something like that. In other words, I want to process every parameter separately (I don't care of definition, even if it will be something like
MACRO("TheName",
Elem1,
Elem2,
Elem3
)
There could be more elements, there could be less. I have tried V_ARGS (I need it only for gcc), but I can only copy all the elements by that, not to process them separately.
What can I do?
P.S. Because of some reasons, I can't use Boost.
I am trying to format currency that will always contain 2 decimal digits, but if there are extra digits of accuracy to display up to five. As an example:
for value = 5.0
display: $5.00
for value = 5.023
display: $5.023
for value = 5.333333333333333
display: $5.33333
I have been playing with the .ToString() formatting, but I can't seem to find the right match of options.
Clarification:
I want to show from 2-5 decimals, truncating zeros after the second digit.
for value = 5.000000000000000
display: $5.00
for value = 5.333333333333333
display: $5.33333

how to revise these code ?
I have an analysis that can be parallelized over a different number of processes. It is expected that things will be both IO and CPU intensive (very high throughput short-read DNA alignment if anyone is curious.)
The system running this is a 48 core linux server.
The question is how to determine the optimum number of processes such that total throughput is maximized. At some point the processes will presumably become IO bound such that adding more processes will be of no benefit and possibly detrimental.
Can I tell from standard system monitoring tools when that point has been reached?
Would the output of top (or maybe a different tool) enable me to distinguish between a IO bound and CPU bound process? I am suspicious that a process blocked on IO might still show 100% CPU utilization.
How to make this method return boolean value, depending on query return. False - nothing, True - data exists. Before i just returned int from uniqueQuote.Count() but does not look like great method. Thank you!
private bool CheckEnquiryUser(int enquiryId, Guid userId)
{
int selectedEnquiryId = enquiryId;
Guid currentUserId = userId;
Entities ctx3 = new Entities();
var uniqueQuote = from quot in ctx3.Enquiries.Include("aspnet_Users")
where quot.EnquiryId == selectedEnquiryId &&
quot.aspnet_Users.UserId == currentUserId
select quot;
bool exist = uniqueQuote;
return exist;
I'm working on a windows forms application that uses a DataGridView. Some of the cells contain a DataGridViewComboBox. In some cases, I have several values to display in the combobox. For that scenario, it would be better to use a ListBox instead of a ComboBox.
Is it possible to use a multi-column listbox within a DataGridView instead of a ComboBox?
If so, can you point me in the right direction?
Thanks much.

hey I'm writing on an Server-Client program
but when my client sends something, it never reaches my server!
I'm sending like this:
public void Send(string s)
{
char[] chars = s.ToCharArray();
byte[] bytes = chars.CharToByte();
nstream.Write(bytes, 0, bytes.Length);
nstream.Flush();
}
and Receiving in a background thread like this
void CheckIncoming(object dd)
{
RecievedDelegate d = (RecievedDelegate)dd;
try
{
while (true)
{
List<byte> bytelist = new List<byte>();
System.Threading.Thread.Sleep(1000);
int ssss;
ssss = nstream.ReadByte();
if (ssss > 1)
{
System.Diagnostics.Debugger.Break();
}
if (bytelist.Count != 0)
{
d.Invoke(bytelist.ToArray());
}
}
}
catch (Exception exp)
{
MSGBOX("ERROR:\n" + exp.Message);
}
}
the ssss int is never 1
whats happening here???
Hey all,
I'm practicing Jquery and I've written this simple Jquery statement:
var someText = $("table tr td").text();
Should this not return all text of td elements found within tr's that are found within tables? How do I fix this? Currently when I run this, it says that table tr td is null, but I have a table on the page I'm testing on.
Thanks!
Basically, this question with a difference...
Is it possible to capture print output from a TSQL stored procedure in .NET, using the Entity Framework?
The solution in the other question doesn't work for me. It works with the connection type from System.Data.SqlClient but I'm using the one from System.Data.EntityClient which does not have an InfoMessage event. (Of course, I could just create an SQL connection based on the Entity connection settings, but prefer to do it directly.)
Is it possible to get the name of a node using minidom?
for example i have a node:
<heading><![CDATA[5 year]]></heading>
what i'm trying to do is store the value heading so that i can use it as a key in a dictionary,
the closest i can get is something like
[<DOM Element: heading at 0x11e6d28>]
i'm sure i'm overlooking something very simple here, thanks!
MYMESSAGE = "<div>Hello</div><p></p>Hello"
send_mail("testing",MYMESSAGE,"[email protected]",['[email protected]'],fail_silently=False)
However, this message doesn't get the HTML mime type when it is sent. In my outlook, I see the code...
This simple test, of course, works as expected:
scala var b = 2
b: Int = 2
scala b += 1
scala b
res3: Int = 3
Now I bring this into scope:
class A(var x: Int) { def +=(y:Int) { this.x += y } }
implicit def int2A(i:Int) : A = new A(i)
I'm defining a new class and a += operation on it.
I never expected this would affect the way my regular Ints behave.
But it does:
scala var b:Int = 0
b: Int = 0
scala b += 1
scala b
res29: Int = 0
scala b += 2
scala b
res31: Int = 0
Scala seems to prefer the implicit conversion over the natural += that is already defined to Ints. That leads to several questions...
Why? Is this a bug? Is it by design?
Is there a work-around (other than not using "+=")?
Thanks
I am aware of array_walk() and array_map(). However when using the former like so (on an old project) it failed
array_walk($_POST, 'mysql_real_escape_string');
Warning: mysql_real_escape_string()
expects parameter 2 to be resource,
string given.
So I went with this slightly more ugly version
foreach($_POST as $key => $value) {
$_POST[$key] = mysql_real_escape_string($value);
}
So why didn't the first way work? What is the best way to map values of an array to a function?
Ok, I have a Preferences activity set with an XML layout.
Here I have a couple of Preferences that open some dialogs. On these preferences I want to have an arrow on the right of them like in the screenshot. How I do this, is something related to the theme ?
First screenshot is how I want to look, second is what I have now.
