DataTable Webmethod only works with thread.sleep
DataTable Webmethod only works with thread.sleep
I'm trying to serialize a DataTable return to use on a WebMethod its just
simple like that:
DataTable dtResult = Occurrences.Search(....);
The thing is, if I, immediatly type
return dtResult.Rows.Count.ToString();
It will return "0".
But if i add just after the first line:
System.Threading.Thread.Sleep(2000);
Everything works fine and the row count is 2.
Since when DataTable fetching is asynchronous?

collect acceleration data for 10 seconds using AsyncTask
collect acceleration data for 10 seconds using AsyncTask
I have searched for a clear answer for this but I have not found one. The
Android application will start the AsyncTask to collect accelerometer data
once a button is pressed. I want the AsyncTask to stop after 10 seconds.
Basically trying to save a 10 second chunk of acceleration data to be
process by another part of my application. Is there a way to control the
time the AsyncTask runs for?
Thank you.

I want to get all files with a specific extension. The following code is
working fine.
String extension = "";

Fetch a page with cookies using Python requests library
Fetch a page with cookies using Python requests library
I'm just studying the requests
library(http://docs.python-requests.org/en/latest/), and got a problem on
how to fetch a page with cookies using requests.
for example:
url2= 'https://passport.baidu.com'
parsedCookies={'PTOKEN': '412f...', 'BDUSS': 'hnN2...', ...} #Sorry that
the cookies value is replaced by ... for instance of privacy
req = requests.get(url2, cookies=parsedCookies)
text=req.text.encode('utf-8','ignore')
f=open('before.html','w')
f.write(text)
f.close()
req.close()
when I use the codes above to fetch the page, it redirects to the login
page, also I see the login page in 'before.html', it refers that actually
I haven't logged in successfully.
But if I use URLlib2 to fetch the page, it works properly as expected.
parsedCookies="PTOKEN=412f...;BDUSS=hnN2...;..." #Different format but
same content with the aboved cookies
req = urllib2.Request(url2)
req.add_header('Cookie', parsedCookies)
ret = urllib2.urlopen(req)
f=open('before_urllib2.html','w')
f.write(ret.read())
f.close()
ret.close()
When I use these codes, it saves the login page in before_urllib2.html.

Is there a way to frame a specific page element?
Is there a way to frame a specific page element?
So, I'm working on a web page, and I want to be able to let users give
feedback using google moderator. In order to help the user experience, I
want there to still be the logo and navigator bar across the top of the
page. The way I have it set up now is with frames. I have one frame on top
containing the logo and navigator bar, and the bottom frame being the
google moderator page. This is effective, but I would prefer it if there
wasn't that pesky grey navigation bar (the one with the links to search,
use youtube, etc.). I was poking around with the source-code and found
that if one where to go to
http://www.google.com/moderator/#16/e=1fe6a2/html/body/div[1]
you would have exclusively the navigation bar. Is there a way to link to
just the body? If not, is there a way to make a frame that excludes a
specific page element? If none of those would work, is there a way to crop
the top off? Any of the above options would be preferable over the current
layout. Any help is much appreciated. Thanks!

Multiplayer Flash Game with Java Server problems
Multiplayer Flash Game with Java Server problems
Alright, basically I've been trying to find out how to set up a
multiplayer flash game, recently I have concluded to code my own server
using Java. I have finally managed to do so after hours of trying and I
have bumped into a snag. Here is my server & client code.
**Server**
import java.net.*;
import java.io.*;
public class ServerFlash
{
public static void main(String[] args) throws IOException
{
ServerSocket serverSocket = null;
Socket connection = new Socket();
InputStream in = null;
boolean listening = true;
try
{
serverSocket = new ServerSocket(14804);
System.err.println("The server is now bound to port.");
}
catch (IOException e)
{
System.err.println("Could not bind server to port.");
System.exit(-1);
}
while (listening)
{
connection = serverSocket.accept();
if(connection!=null)
{
System.err.println("Connection to client has been
established.");
in = connection.getInputStream();
listening = false;
}
}
while (!listening)
{
int data = in.read();
if(data!=-1)
{
System.err.println(data);
}
}
}
}
**Client**
var server = new Socket();
server.connect("[insertmyip]",14804);
server.addEventListener(Event.CONNECT, onConnect);
server.addEventListener(Event.CLOSE, onClose);
server.addEventListener(IOErrorEvent.IO_ERROR, onError);
server.addEventListener(ProgressEvent.SOCKET_DATA, onResponse);
server.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecError);
function onConnect(e:Event)
{
trace("Connection Established.");
}
function onClose(e:Event)
{
trace("Socket has been Close.");
}
function onError(e:Event)
{
trace("An Error has occured." + e);
}
function onResponse(e:Event)
{
trace("Responce has been recieved.");
}
function onSecError(e:Event)
{
trace("A SecError has occured.");
}
When I launch the server everything is okay. However when I launch the
client, it successfully connects to the server, but all of a sudden the
server receives data from the client (if you read the code the server
reads incoming data and displays it) and displays around 15 lines of code
and it does not accept any new data from the client. HOWEVER this only
happens when the client is launched from a website (or a folder) BUT it
works normally when I open the client as a test in Adobe Flash Pro.
If you require files and hand them over.

How can I copy a command line arg to a variable in c? If was to do the
following.
myprog "Hello, world!"

Assuming only 1 parameter will be passed in always.

int i;

Can JaxRsController access jax-rs resources that are in my custom grails plugin?
Can JaxRsController access jax-rs resources that are in my custom grails
plugin?
I'm using Grails 2.2 and the JSR 311 jax-rs plugin.
I've created a custom Grails plugin (call it MyPlugin) using jax-rs
resources, and installed it in another Grails application (call it
MyApplication), which is also built around jax-rs.
I am having issues reaching any of the MyPlugin resources from
MyApplication - it seems like the JaxRsController is not aware of the
resources embedded in MyPlugin. I seem to recall reading that it only
searches 'MyApplication/grails-app/resources' for jax-rs resources, which
would explain it.
Is there a way to make the JaxRsController aware of MyPlugin's jax-rs
resources? If not, is there a better approach than installing a jax-rs
plugin inside another jax-rs app?

SQL Update values in table A with multiple values from table B
SQL Update values in table A with multiple values from table B
I'm trying to update products' prices in table A with prices from table B
based on their product code.
There are about 50,000 products in table A but only 200 in table B. So I
want those 200 prices in table B to replace the prices of those products
in table A by matching the product code in both tables.
Can anyone advise me on how to go about doing it?

How to initialise a pointer to a pointer when the final address isn't known?
How to initialise a pointer to a pointer when the final address isn't known?
In this example, I'd like to pass a pointer pointer to the future,
not-yet-allocated someObject to a function. (Please don't ask why.)
int main(void) {
functionThatNeedsSomeObject();
SomeClass someObject(0);
}
I'm trying to do that using a pointer to a pointer. This is my attempt:
int main(void) {
SomeClass** ppSomeObject;
functionThatNeedsSomeObject( ppSomeObject);
SomeClass someObject(0);
*ppSomeObject = &someObject;
}
But in my code, ppSomeObject is uninitialized when it is passed. Of course
the second-layer pointer can't point to the object, but how can I make the
first-layer pointer point somewhere that I can change later, when
someObject is created?
Should I do something like this? Even if it works, creating an
intermediate pointer feels unnecessary.

functions as global var blasts = [];!
I came from C# world and I really don't know why that array is undefined
after being declared and pushed couple values into it.
Thank you.

when do java infinite loops stop?
when do java infinite loops stop?
I read about infinite loops and found out in some languages it will stop
when stack overflows or reached the allotted maximum memory. Others will
loop forever depending on the type of program and language. My question
is, do java infinite loops stop? I'm just curious because java has a
garbage collector, that reuse memory when there's memory leak in case of
reaching allotted maximum memory and stack overflow.
Also,will this kind of infinite loop stop?

How can we detect when a hidden form field was changed dynamically? If it
was changed, then display an alert?
A JQuery UI (DatePicker) is used to change the hidden form field.
<input name="textbox" id="alternate" type="hidden" size="30"
onchange="alert('changed')" />

So then I need to create an IF to verify if this message exist [If this

Any help? Thanks.

HTTP Basic Auth Rails Admin
HTTP Basic Auth Rails Admin
I'm trying to use basic http authentication on my admin panel. I'm using
Rails Admin.
I want to require http basic auth for the admin login.
In my application controller I'm trying the following:
before_action :basic_auth_admin, if: :admin_url?
private
def admin_url?
request.url.scan(/\/{1}admin.*/).size > 0
end
def basic_auth_admin

In Chrome/Firefox I cannot access the admin login. Chrome continues to
prompt for credentials and Firefox just continues loading.
Please advise. If there's a better way to accomplish my goal please let me
know.

Loading parts of the knockout model dinamically from database on demand
Loading parts of the knockout model dinamically from database on demand
I store my data in a relational database table. Each record contains the
fields of a form and the name of the template
(http://knockoutjs.com/documentation/template-binding.html) to use for
them. (There are different record structures for different templates, but
the details are not important here.) I can get one record by ID in a
$.getJSON call, make a ko.mapping.fromJS from it and ko.applyBindings the
result on my HTML page. This works well so far for any given ID.
Now there is an other table with master-detail connections, i.e. I can get
for a master ID the array of ID-s of the child records. I'd like to
display the child records below the master (each child with its own
template, of course, which might be different) like in a tree view, when
the user expands that branch of the tree. I can't load the whole database
into the client browser, only the parts asked by the user should be
loaded.
I was thinking about foreach-binding
(http://knockoutjs.com/documentation/foreach-binding.html) the array of
ID-s somehow (seems to be natural), but there are a number of issues with
it:
KO wants the whole data structure to be present when binded. Now I have
the ID-s only, which refer to the records indirectly. My data will arrive
later, via async AJAX call.
Appending a new child record needs to fetch a new ID from the server (a
database sequence's next value). We must know the template of the new
record too, but it will be given somehow (the master has a default for new
children.)
I have a js object which caches the records already loaded (the key is the
ID, the value is the record), but I can't phrase the connection with
foreach.
Do you know some tricks to bind non-existing data (I mean currently not in
the model), or any method to handle this indirect reference?
Perhaps I could manipulate the DOM manually for the array, but this is
exactly what the foreach-binding does (I think), so I'd prefer the builtin
way, if possible.
Or, could I use KO's foreach to build empty slots for the children, and
bind to the slots later, when the AJAX succeeds? But how can I reference
these parts of the DOM?
Thanks.

I want to move all matched char in a string to the end of it.
For example:

chafof -> chaoff
I tried with this:

But it just make: chafo -> chaof, not chafof -> chaoff
Can anyone help me out?

execute code in java fields
execute code in java fields
I'm in a position where I have referenced a static field variable to a
custom class. I need to make alterations to the variable with methods from
the class it references. I can not instantiate the class under
construction. Simplified example:
public class House {
private static MaterialsRequired matsReq = new MaterialsRequired();
private String size;
private House(String size) {
this.size = size;
}
public static MaterialsRequired getMaterialsRequired() {
}
public static void Build(String size) {
new House(size); //Do I need to put 'this(size)' here?
//some code here to expend the materials required factored based on size.
}
To construct the house I need to know the materials required (for standard
size). To know the materials required I need to call the addMaterial()
method of MaterialsRequired. What do I do?
EDIT: I need to call the addMaterial() method repeatedly on matsReq. Maybe
ten times. When I call House.build() I want the matsReq to have been
altered by method calls (if my question was unspecific). Also it doesn't
satisfy me to just set the materials required every time the build() or
getMaterialsRequired() methods are called.

Is it possible to set the the value of the name in wufoo form fields?
I have a Wufoo form am I am trying to save the data captured from the form
to Solve360.
I have been trying to look for a way on how to change the value of the
name attribute of the input tag but I can't seem to find a way how to do
it.
Here is the code of the form looks like:
<input id="Field3" name="Field3" type="text" class="field text medium"
value="" maxlength="255" tabindex="1" onkeyup="handleInput(this); "
onchange="handleInput(this);" required="">
I've been looking at the wufoo backend for the option to change the value
in the name field from Field3 to something more correct like name, age,
etc.

how to convert preg_replace http:// & www
how to convert preg_replace http:// & www
Here i have 3 type of links users gives in their $description.
www.Apple.com
http://www.Apple.com
http://apple.com
First i'm using this to make $description safe
$description = preg_replace('<[^A-Za-z0-9-.?#%=_&():/]>', '',
"$description");
Second I did this but here i got stuck.
$description = preg_replace('/(www.[^\s]*)/i', '<a href="//$1"
target="_blank">$1</a>', $description); //This converts www.apple.com
$description = preg_replace('/(http[s]?:\/\/[^\s]*)/i', '<a href="$1"
target="_blank">$1</a>', $description); // This converts http://apple.com
www. works and http:// doesn't works because they both combine together so
is there any process by which this can be undone Also Please tell me if
there is something wrong i have coded which can be harmful or better way
to do this.

$description = preg_replace('/(www.[^\s]*)/i', '<a href="//$1"
target="_blank">$1</a>', $description); //This converts www.apple.com
$description = preg_replace('/(http[s]?:\/\/[^\s]*)/i', '<a href="$1"
target="_blank">$1</a>', $description); // This converts http://apple.com
www. works and http:// doesn't works because they both combine together so
is there any process by which this can be undone Also Please tell me if
there is something wrong i have coded which can be harmful or better way
to do this.
Tablesorter becomes non-functional after jquery page load
Tablesorter becomes non-functional after jquery page load
I have page that has a variable refresh rate, and displays a couple of
tables. The tablesorter.js code works fine initially, but after the first
refresh its non-functional.
I've tried placing the tablesorter function inside the click function for
each branch, or at the end of the whole click function or inside the load
function -and- After looking at the docs for tablesorter, I have tried
calling $("#workstation-table").trigger("update", true) in all the
forementioned scenarios. Everytime it's the same. Doesn't work after first
refresh. Any advice would be great.

How to get authors name's posts?
How to get authors name's posts?
I have a site where users are not logged in and they can post, I am using
a plugin called http://wordpress.org/plugins/user-submitted-posts/. Their
posts are considered as posted by Admin, however, since in the form when
they submit they can insert their name, wordpress shows in the admin panel
their name.
By doing this i can get a list of the names:
<ul>
<?php
$args= array(
'posts_per_page' => -1
);
query_posts($args);
?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<?php echo get_the_author(); ?>
</li>
<?php endwhile; ?> <?php endif; ?>
</ul>
But if I add this:
<?php echo get_the_author_posts(); ?>
I get a list of the different names but each of them shows me the same
number of posts, e.g.:
Name1 22
Name2 22
Name3 22
Name4 22
This happens because these are not actual users and their are posting on
the behalf of the admin.
So how can I get the posts number based on the authors names as they
display on the admin panel and not by registered users?
I have a site where users are not logged in and they can post, I am using
a plugin called http://wordpress.org/plugins/user-submitted-posts/. Their
posts are considered as posted by Admin, however, since in the form when
they submit they can insert their name, wordpress shows in the admin panel
their name.
By doing this i can get a list of the names:
<ul>
<?php
$args= array(
'posts_per_page' => -1
);
query_posts($args);
?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<?php echo get_the_author(); ?>
</li>
<?php endwhile; ?> <?php endif; ?>
</ul>
But if I add this:
<?php echo get_the_author_posts(); ?>

Passing F keys to Emulated Telnet session in Powershell (TCP)
Passing F keys to Emulated Telnet session in Powershell (TCP)
I have figured out a way to connect to a telnet server using powershell.
The script allows to create a tcp socket type connections and pass
commands.
Basically, I use System.Net.Sockets.TcpClient System.IO.StreamWriter and
then a sequence of WriteLine and Flush methods.
I have no problem passing regular ascii type lines using WriteLine. But
how do I pass on the F3 key.
F3 has no ASCII code, and I don't know what byte sequence is sent to
telnet when I hit F3. I need F3 to do certain tasks in the telnet session.
Any assistance is highly appreciated. Here is an example of my code:
$x = [char]114 + [char]189 <-- F3 key ???????????????????
Function Get-Telnet
{ Param (
[Parameter(ValueFromPipeline=$true)],
[string]$RemoteHost = "HostnameOrIPAddress",
[string]$Port = "23",
[int]$WaitTime = 6000,
[string]$OutputPath = ""
)
#Attach to the remote device, setup streaming requirements
$Socket = New-Object System.Net.Sockets.TcpClient($RemoteHost, $Port)
If ($Socket)
{ $Stream = $Socket.GetStream()
$Writer = New-Object System.IO.StreamWriter($Stream)
$Buffer = New-Object System.Byte[] 1024
$Encoding = New-Object System.Text.AsciiEncoding
#Now start issuing the commands
$Writer.WriteLine([char]08)

Add row to dataframe based on presence criteria
Add row to dataframe based on presence criteria
I am trying to find a way to add rows based on criteria in a data frame. I
essentially want to take a data frame and insert values that are missing.
Here is what I start with:
Plot Species Status
1A ABBI L
1A PIEN D
1B ABBI D
1B PIEN L
2A ABBI L
I would like the ability to search the Plot column for 1A, 2B and 3A.
Since 1A is present, there would be no action, but 2B and 2B would be
added to the data frame. For missing values, I will always want to enter
the Plot number and 0 for everything else. The end result looking like
this:
Plot Species Status
1A ABBI L
1A PIEN D
1B ABBI D
1B PIEN L
2A ABBI L
2B 0 0
3A 0 0
Thanks for your help!

how to start placement of action buttons from the left in action bar
how to start placement of action buttons from the left in action bar
I am new to android development. Hence, I'm still in the
getting-the-hang-of-it mode. I have started off my app by creating an xml
file in the res/menu folder, the code for which is shown below. What I
need help with is placing the first (add) button in the left hand corner,
where the title bar is supposed to be located, followed by the remove
button in the centre, and finally the overflow menu in the last third. I
want these three entities to be evenly spaced out. Additionally, I have
managed to get rid of the app name and icon from the left hand corner.
Any help will me much appreciated.
Thanks in advance

Weird back button (Alt-Left) behavior in Eclipse
Weird back button (Alt-Left) behavior in Eclipse
Not exactly a programming question, but I figured I'd get more response
here than in SU. Tag 'java' added because I'm programming in Java. Feel
free to edit/move question as appropriate.
I'm using Eclipse Kepler IDE, and I'm having this annoying weird behavior
from the Back function. I can't remember if I had this behavior in Juno
version but I think not - that's what I'm here to confirm, if this is a
bug or I need to adjust some setting in Eclipse.
Imagine the following code points:
Point A
Point B
Point C
When my editing cursor is at point A and I hit F3 (Open Declaration),
Eclipse takes me to B. If I hit F3 again, Eclipse takes me to C.
All that is well, but when I hit the Back button or press Alt+Left from C,
I'm being taken back to A. If I then hit Forward (Alt+Right), I'm taken to
B and the Forward button is disabled! (I can't go forward to C).
Current Behavior:
F3: A -> B -> C
Back: C ------> A
Forward: A -> B
This doesn't seem right at all, because I would expect going back from C,
I should reach B, and then to A. Following that, going forward from A, I
should go to B, and then to C.
Expected Behavior:
F3: A -> B -> C
Back: C -> B -> A
Forward: A -> B -> C

Unable to let ajax calendar appear twice from the textbox
Unable to let ajax calendar appear twice from the textbox
I have created a search function where the user will be able to select the
search field from the dropdownlist. For example, the field can contain
data such as default value "---Select---", "incidentdate", "memberid". In
my condition, i have put this
if (ddlCategory.SelectedItem.Text.Equals("incidentdate"))
{
CalendarExtender myCalExt = new CalendarExtender();
myCalExt.TargetControlID = "txtData";
myCalExt.Enabled = true;
Place1.Controls.Add(myCalExt);
}
if (!ddlCategory.SelectedItem.Text.Equals("--- Select ---"))
{
txtData.ReadOnly = false;
}
else
{
txtData.ReadOnly = true;
}
This basically allow the ajax calendar to appear whenever the user select
the ddl text incident date. The user will then have to click the search
button before the webapp will display any data. However, if the user
failed to search a data from the date he select from the calendar, the
user will not be able to re-select the date as the ajax calendar will not
appear again. In fact, tt will only re-appear if the user re-select the
"incidentdate".
Why is this so? My condition has already mentioned that if the Text equals
to incidentdate, the calendar will appear.
Regards.

Java copy multi-d array, random errors
Java copy multi-d array, random errors
I have been debugging my implementation of Game of Life, and my main
problem looks like its coming from how I use arrays.
public boolean[][] oldState;
public boolean[][] newState;
private boolean gameState = true;
public LifeBoard(Seed seed) {
oldState = seed.getSeed();
newState = new boolean[oldState.length][oldState[0].length];
run();
}
public void run() {
//debug code to run for x generations
for (int i = 0; i < 5; i++) {
BoardPrinter.print(oldState);
evaluateCells();
oldState = newState;
}
BoardPrinter.print(oldState);
System.out.println("game over");
}
the boolean[][] from Seed is a 5x5 grid, all false (dead) except the 3
horizontal middle cells in the middle row
00000
00000
0+++0
00000
00000
evaluateCells() looks at each cell in the grid, looks at the 8 cells
around it, counts them, and based on the number of neighbors it writes a
new value to newState.
What should happen: use oldState to calculate newState, copy newState to
oldState, then go back through newState, writing each cell again based on
the new oldState.
What really happens: the first generation works correctly, but after that
the results are increasingly weird, it evaluates cells to be false that I
know to be true, etc. The problem seems to be in the way I am copying the
arrays.
If I initialize a 3rd blank array blankState[][] = new boolean[5][5]; and
during the loop in run say:
public void run() {
//debug code to run for x generations
for (int i = 0; i < 5; i++) {
BoardPrinter.print(oldState);
evaluateCells();
oldState = newState;
newState = blankState;
}
BoardPrinter.print(oldState);
System.out.println("game over");
}
...then the game works correctly for an additional 1 generation, then the
weird garbage returns.
I have 2 questions: first, it looks like I have to use System.arraycopy(),
but unless someone tells me about a version for multidimensional arrays, I
will have to write a simple loop.
My real question: why do you have to use this special System method to
copy an array? Why can't you use the = operator?

Is There Better Way to Validate SqlXml in CLR?
Is There Better Way to Validate SqlXml in CLR?
I need to validate xml in sql server against an xsd. The xsd is too
complex to use with XML SCHEMA COLLECTION, so I am writing a SQL CLR
function to do it. I have two issue with how I have "had" to write the
code. Code is VB.NET targeting 2.0, btw, thought I think I run into the
same issue in C#. If not happy to switch.
[1] I cannot seem to attach setting to the reader created by
SqlXml.CreateReader so I have to load into an XmlDocument to perform the
validation. I also cannot just load the SqlXml straight to XmlDocument--I
would have to do extra type conversions.
Am I missing something or is that just the way it is?
[2] I hate that I am using a shared member to pass the validation result
from the event handler and then back to the caller. This is fine in my
first specific usage where I no there is a sequence of individual calls.
But if I ever tried using this with multiple callers or in set operation I
fear the results would be suspect.
Is there a way around this?
