Objective C adding C++
Objective C adding C++
I have been given some C++ classes to incorporate into my Objective C
project. I've never done this before, so I have to ask:
Is there something special I need to do or can I just rename the .cpp to .mm?
What about importing (or including) the .h file? Anything special I need
to do there?
Just baby steps here. Thank you.

Pointers in B Tree
Pointers in B Tree
I read about B trees and understand their input, delete methods. I read
with an introduction like this:
When we build structures on disk, we must deal with certain realities of
access and transfer time:
Random access to disk typically requires on the order of 10-20 ms access
time to position the head and wait for data to come up under it.
Once the head position is right, data can be transferred at rates in
excess of 1 million bytes/sec.
Observe, then, how total transfer times behave for different size blocks
(assuming a fairly fast 10 ms access time, and 1 megabyte/sec transfer
rate)
So, B Tree Data Structure is made for serving from disk ( which is what
makes them great for Databases ). But when I tried to implement it, I hit
this problem.
Normal B Tree diagrams shows pointers to child nodes which then descend
down to leaves.
But how do I make pointers on the disk? Is it like a file name ?

Access igraph R objects from Python
Access igraph R objects from Python
I have a graph object created with the igraph R package. If I understand
the architecture of the igraph software package correctly the igraph R
package is an interface to use igraph from R. Then since there is also a
igraph Python interface I wonder if it is possible to access my igraph
object created with R via Python directly. Or if the only way to access
and igraph R object from Python is to export the igraph R object with
write.graph() in R and then import it with the igraph R package.

Function that checks width of an image loaded by user randomly returns 0
Function that checks width of an image loaded by user randomly returns 0
I was trying to write a function that would check if the image I chose via
input[type=file] is exactly 700 px wide and if not - reject this image. I
succeeded, however, sometimes this function randomly returns 0 and I need
to load the same image a couple of times until it reads its width
correctly. Any ideas on how to improve this code? Thanks in advance!
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
var img = new Image;
img.src = e.target.result;
if(img.width == 700) {
DoSomeStuff();
} else {
alert("This image has to be 700 px wide, but is " +
img.width + " px wide. Try again!");
input.value = "";
}
};
reader.readAsDataURL(input.files[0]);

In SAO architecture should single API do everything or API should be spilt
as multiple action
We have an app which is exposing api(RESTful) to UI for purchasing a item.
I have a question regardinng API design. Lets say the following action
should be taken in order
Item to be chosen for purchase
Next give the address to be delivered to
My question is should we design a single api which gets both data perform
both? Or should we desgin two api calls one that creates a purchase record
and second that update the address to be delivered to?

How to add space between menu and dropdown submenu
How to add space between menu and dropdown submenu
I'm working on a CSS3 full width dropdown menu, but some details i can't
get right. :-(
What i try to achieve is this:
http://i.stack.imgur.com/Egk0P.png
You can see there is a little 20px space between the mainmenu and the
submenu. In this example i used a top-margin:20px for the ul submenu. But
that doesn't really work, because you will leave the hover-area with your
cursor and the submenu wil dissapear. The dropdown only works if the
ul-container of the submenu "touches" the hover-area.
It did tried using the ul:before trick to add an empty block before the
submenu ul, but somehow that doesn't work. :( It doens't take space like a
block should do. It's just adding the content right over the ul element.
What do i overlook or doing wrong here? :( Is there a better way to add a
little bit of empty "hoverspace" above the submenu?
Your help would be very helpfull :-).

So I try to enable script execution (as I did for PowerShell outside of
PyCharm):
Set-ExecutionPolicy RemoteSigned
but get the following error (I avoided this error outside of PyCharm by
running PowerShell as administrator):
Set-ExecutionPolicy : Access to the registry key

So what can I do to be able to use virtualenv from the PyCharm terminal?

SQL statement exception when MDB table name contains #32
SQL statement exception when MDB table name contains #32
I am using Delphi 7 and am trying to build a SQL query statement which
will be used with a Microsoft Access MDB file. The code is below:
dm.tblUserTableQ.Close;
dm.tblUserTableQ.sql.Clear;
dm.tblUserTableQ.sql.Add('select count(*) as QTY from '+
Tables.items[Tables.itemindex]);
The above code works fine as long as the MDB table name chosen has no #32
space characters in it. IOW, if the table name is named "ZIPCODES", the
query works fine. However, if the table name is named "ZIP CODES", the
sql.Add statement triggers an exception: Syntax error in query. Incomplete
query clause.
I have tried enclosing the table name within #39 characters, but that
doesn't help. IOW:
'select count(*) as QTY from '+ #39 + Tables.items[Tables.itemindex] + #39
I've tried #34, but that doesn't help either.
Other than renaming the table, is there any solution?

Allow Java to recognize input not equal to a wanted value
I am new to both Java and this site so please have mercy on any mistake I
may make, I am at my wits end!
I am trying to make a program that calculates the speed of sound through
different mediums. As of now the program will ask the user for input on
the distance and allow input, same for the medium. I created several cases
that will calculate the the answer of the given medium which work
properly.
The issue is when I try to create a loop that recognizes if the medium
input is not one of the 4 options available. I was able to successfully
create a loop that recognizes if the distance input is not a numeric value
and tried using similar principles for the medium input but either keep
getting stuck in infinite loops or getting the message I created for a
wrong entry when I entered the right option. I have tried the basic loops
that I have been taught: for, do-while, etc., but am stuck. Any and all
suggestions are appreciated, thank you so much!

WAN Access Issues on LAMP Server
WAN Access Issues on LAMP Server
I am running a LAMP server and having trouble connecting over the internet.
I confirmed everything is working fine locally. All other PC's on my
network can access the server over the LAN.
The server is wired directly to one of the gigabit ports on my modem and
ports have been forwarded accordingly.
I recently moved and switched from FIOS to Comcast. This configuration
worked fine on FIOS, but not so much here on Comcast. I have a Docsis 3
modem and am on the Extreme 105 package if that is relevant to anyone.
A ShieldsUp port scan showed all ports in stealth mode.
When attempting to connect from the WAN ip, it simply fails to connect.
Also may be worth mentioning that neither FTP, or SSH are working either,
despite having the ports forwarded properly. (I say properly in that the
same configuration worked on my FIOS connection before I moved)
Has anyone else seen this issue with Comcast?

Changing msvcrt.dll on Windows System
I'm using MinGW 4.8.0 (posix, dwarf-2) for building c++ code. Looking with
dumpbin I noticed the MinGW links to msvcrt.dll that on my on Windows 7 is
at the version 7.0.7601.17744 and on Windows Xp SP3 is at version
7.0.2600.5512.
Well I want that MinGW links to a newer version to Microsoft C Runtime
library so I've two choice: use a precompiled version of MinGW that
arleady links to newr C Runtime or rename for example msvcrt110.dll to
msvcrt.dll and deply the application with that library.

Coin Toss game in R
Coin Toss game in R
So trying to make a simulation of a coin toss game where you double your
money if you get heads and half it if you have tales. And want to see what
you get after n throws if you start with x money
However I'm not sure how to tackle this problem in a nice clean way,
without just doing a forloop to n.
Is there some clean way to do this?

Unable to fetch tab id from sub tab in Jquery
Unable to fetch tab id from sub tab in Jquery
I am using a tab structure as below:
<div id="tabs">
<ul>
<li><a href="#dia_details">Details</a></li>
<li><a href="#tab_raise_req">Raise Req</a></li>
</ul>
<div id="dia_details">
<div id="sub_tabs">
<ul>
<li><a href="#DIA_details">DIA Details</a></li>
<li><a href="#allocate_ba">Allocate BA</a></li>
</ul>
<div id="DIA_details>
<form>
--Code--
</form>
</div>
<div id="allocate_ba">
<form>
--Code--
</form>
</div>
</div>
</div>
<div id="tab_raise_req">
<form>
--Code--
</form>
</div>
When I am in a sub tab and want to save the particular tab for which I
have defined a button, I wanted to obtain the tab id of the currently
active tab.....which is one of the sub tabs.
For this I was using the below function in Jquery:
// Save Changes button click
$("#save_changes_id").click(function() {
// To retrieve the current TAB and assign it to a variable ...
var curTab = $('.ui-tabs-active');
var curTabPanelId = curTab.find("a").attr("href");
responseData = doAjaxCall($(curTabPanelId + " form"));
if(responseData == 1)
showMessage('status_msg', 'Project details updated successfully',
'green');
else
showMessage('status_msg', 'Error: Please check all the fields',
'red');
});
Here the function is returning the id of the parent tab instead of the sub
tab. I tried using addClass and removeClass but of no use.
Please suggest a solution for this. Thanking you in advance.

Visual Studio shortcut to get back to coding pane after terminating the run using Shift+F5
Visual Studio shortcut to get back to coding pane after terminating the
run using Shift+F5
This was very tricky to Google ,however, a very simple question in mind.
Instead of wasting lots of time filtering the Google search results I
prefer to ask my Stack fellow developers.
Scenario
Program is running
I terminate it using Shift + F5
I want to continue making change to the code BUT the focus is on some
random Find Usage pane (from resharper) instead of the code itself.
I simply don't want to keep pressing the Tab key until I'm lucky.
Any shortcut available?
Thanks

Trying to implement Jekyll Slideshow but unsure of syntax
I am trying to implement https://github.com/matthewowen/jekyll-slideshow,
however I am unsure of what Matt means in the documention when he says:
For any content that you'd like the slideshow process to work on, use the
filter 'slideshows' in your template, like so:
{{ content | slideshows }}
I am using HTML rather than markdown. My html looks like...
<ul>
<li><img src="assets/images/77_xs650.JPG" alt="Example image" title=""
/></li>
<li><img src="assets/images/650_chop.JPG" alt="Example image" title=""

How do I use the filter 'slideshows' on this data?

Many thanks!

Zip File Entry has custom file extension. C# claims it cannot open
Zip File Entry has custom file extension. C# claims it cannot open
I have a zip file given to us by a 3rd party. In this zip files are custom
files. These are just text files with a different extension, which I
assume is just to frustrate me.
I'm trying to open this files in my C# application, but it keeps throwing
the error that the format is not supported.
Since these are just text files, I feel there must be some way for this to
happen.
If anyone has any ideas, please let me know.
Code:
using (ZipArchive archive = ZipFile.OpenRead(_trailerName))
{
ZipArchiveEntry entry = archive.GetEntry(tableChanged + ".trl");
Stream ms = entry.Open(); //Here is what's causing the issue.
StreamReader reader = new StreamReader(ms);
string allLinesRead = reader.ReadToEnd();
string[] everyCell = allLinesRead.Split('|');
int numRecords = Convert.ToInt32(everyCell[1]);
int numChanged = getRecordNum(tableChanged);
Console.Write(numRecords + "/" + numChanged + " - " + tableChanged);
if (numChanged != numRecords)
{
_errorMessage += "Records updated do not match trailer. (" +
numRecords + "/" + numChanged + ") Please check database. Table
affected: " + tableChanged + Environment.NewLine;
}
}
Error:
The given path's format is not supported.
I know this is specific, but I need advice on what steps I can take to
resolve this.

How to apply a loop on a script for multiple/various sheet names in Google spreadsheet?
How to apply a loop on a script for multiple/various sheet names in Google
spreadsheet?
I'm still learning GoogleApp scripting. Can anyone guide me in the right
direction how to apply the same codes on a Google spreadsheet with
multiple sheets with different sheet names? Maybe I need a script for a
loop?
Thank you for your help in advance!
This is the script I have so far:
function MakeRowGray() {
var sheet =
SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1');
var columnD = sheet.getRange(2, 2, sheet.getLastRow()-1, 1); // Row B
var dValues = columnD.getValues();

spreadsheet?
I'm still learning GoogleApp scripting. Can anyone guide me in the right
direction how to apply the same codes on a Google spreadsheet with
multiple sheets with different sheet names? Maybe I need a script for a
loop?
Thank you for your help in advance!
This is the script I have so far:
function MakeRowGray() {
var sheet =
SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1');
var columnD = sheet.getRange(2, 2, sheet.getLastRow()-1, 1); // Row B
var dValues = columnD.getValues();
var columnE = sheet.getRange(2, 3, sheet.getLastRow()-1, 1); // Row C
var eValues = columnE.getValues();
for (var i = 2; i < dValues.length + 2; i++) {

How to switch back to a view controller without losing data
How to switch back to a view controller without losing data
I have an iCarousel view, which for those of you who don't know what it
is, works a lot like UITableView or UICollectionView. If you'd like, we
can pretend that I'm using one of those.
Anyways, my iCarousel has a bunch of items in it already. They're defined
in a global NSMutableArray by the name of "items". My problem is when I
switch views for a minute away from the carousel, when i switch back, the
items are gone. I believe this is because when i switch views, the
carousel is deallocated or the reference is lost. When i try to reload it,
i use this code:
self.carousel = [[iCarouselExampleViewController alloc]
initWithNibName:@"iCarouselExampleViewController" bundle:nil];
[self presentViewController:self.carousel animated:YES completion:nil];
[self.carousel.carousel reloadData];
This code brings me to an empty carousel. I assume this is because, as
aforementioned, i lost the reference to the view and i had to reallocate
it with the initWithNibName call. Anyways, how do i get around that? I
dont want to lose the data that was in the class. any suggestions? And how
would i go about switching back to a UITableView from a different view
controller in the first place?

Removing values from a TextBox based on a checkbox
Removing values from a TextBox based on a checkbox
i populate a textbox when checkboxes are clicked, with their values (comma
separated) Now i want to remove that value from the textbox when the
checkbox is unchecked.
here is where i am now:
$(document).ready(function () {
$('.checkboxes').change(function () {
if ($(this).is(':checked')) {
if ($('.DISTRIBUTION').val().length == 0) {
var current = $('.DISTRIBUTION').val() + $(this).val()
+ ",";
}
else {
var current = $('.DISTRIBUTION').val() + "," +
$(this).val();
}
}
else if ($(this).not(':checked')) {
var current =
$('.DISTRIBUTION').val().replace(","+$(this).val(), "");
}
$('.DISTRIBUTION').val(current);
});
});
it works great! except for the first value, which does not have a comma in
front of it. how do i handle that situation? How do i find out of the
value to be removed, is actually the first item in the textbox?
here's an example:
apple,pear,peach,banana
when i remove ",pear" and ",banana" it works fine, but when i get to
",apple" it does not work as apple is first and there is no comma.
Thanks!

Cannot remove DOM Element (JavaScript, CreateJS)
Cannot remove DOM Element (JavaScript, CreateJS)
I have a problem removing a DOMElement from the stage. This is how I
created my domElement with createjs Framework.
this.domElement = new
createjs.DOMElement(document.getElementById('nickname'));
this.domElement.x = 580;
this.domElement.y = 200;
this.stage.addChild(this.domElement);
My HTMl code looks like this:
<form id="myForm" style="visibility: hidden">
<input id="nickname" value="" size="10">
Everything works fine till I want to remove "domElement" from the stage.
Here is how I attempted it:
this.stage.removeChild(this.domElement);
I also tried other solutions like :
this.stage.parentNode.removeChild(this.domElement);
Do you have an ideea why I am not able to remove this DOM Element?

xcode Interface Builder is resizing back to a wrong size a UITableViewCell
xcode Interface Builder is resizing back to a wrong size a UITableViewCell
I have a UITableView with 2 different xib files, the first one for iPhone,
the second one for iPad, then I have for both a xib for the custom Cell,
the iPhone version works well, the iPad version (which is bigger) is
automatically resize itself to 320 width, Inside I have a UILabel that
needs to show text in 2 lines, when I set the 2 lines on Interface Builder
even if I had the cell size to 600 for example, it is automatically
resized back to 320
I've setted the class and the names are correct, I don't understand which
relationship there's between the first xib (the iPhone custom cell) and
the second (the iPad custom cell which is resized back to 320)
any advice?

.Net Immutable Collections with WPF DataGrid
.Net Immutable Collections with WPF DataGrid
Has anybody found a nice pattern for binding ImmutableCollections ( from
the MS BCL ) to a WPF DataGrid? To represent mutablility of an immutable
structure I would wrap it with ISubject to track changes and provide new
versions to the datagrid.
ISubject<ImmutableList<T>> <--(binding)--> DataGrid
Has anybody tried something like this before? Any suggestions on how to
model this. The DataGrid obviously needs a mutable collection such as
ObservableCollection directly under it so perhaps the problem can be
reduced to
ISubject<ImmutableList<T>> <-----> ObservableCollection<T>
Any suggestions?

Is Google's Webspeech server request-limiting me, and is there a fix?
Is Google's Webspeech server request-limiting me, and is there a fix?
I've been writing an extension that allows the user to issue voice
commands to control their browser, and things were going great until I hit
a catastrophic problem. It goes like this:
The speech recognition object is in continuous mode, and whenever the
onerror: 'no-speech' or onend events fire, it restarts. This way, the
extension is constantly waiting to accept input and reacts whenever a
command is issued, even after 5 minutes of silence.
After a few days of of development, today I reached the point where I was
testing it in practical use, and I found that after a little while (and
with no change to anything on my part), my onend event started firing
constantly. As in, looking at the console, I would see 18,000 requests
being made in the space of three seconds, all being instantly denied, thus
triggering onend and restarting the request.
I'm aware that it would be optimal to wait for sound before sending a
request, or to have local speech recognition capabilities without the need
for a remote server, but the present API does not allow that.
Are my suspicions correct? Am I getting request limited?

PHP use variable to pass multiple arguments to function
PHP use variable to pass multiple arguments to function
I have a function that expects 9 arguments to be passed to it. The first
argument it expects is a string, the rest are ints.
Here is the function:
getProductPrice('red', 8, 1.6, 2.15, 0, 0, 0, 17.6, 0);
When that gets run, it works fine. However, when I run it like this:
getProductPrice("'red'".','.$arguments);
It does not work.
"'red'".','.$arguments
outputs: 'red', 8, 1.6, 2.15, 0, 0, 0, 17.6, 0
If anyone could tell me how to use the $arguments variable in place of all
the arguments?
What I ended up suspecting was making it not work, is that what $arguments
is outputting is a string, so I looked into how to convert a comma
separated string of numbers into a php function's arguments.
I came across this:
$params = explode(',', $str);
call_user_func_array("func", $params);
I can't figure out how to use this solution for two reasons:
1. I need to pass a string along with the numbers.
2. simply putting my function name where it says "func" in that example
won't work, because it's a cakephp function, which requires me to put
$this->ModelName->functionname, which breaks the first argument in the
call_user_func_array function()
Any ideas how to help me guys?
I could just put the variables that make $arguments output what it does,
but it's a ton of complicated logic and math to get each of those numbers,
so my function calls would look ridiculous.
Thanks again.

Lilypond: controlling clef and key signature visibility, aligning markup
My effort to create a document with six incipits from different pieces is
running into a couple of problems. Can anyone help? I am pasting my code
below (I've reduced the example somewhat for the purposes of asking the
question).
Problem 1: How can I hide the clefs and key signatures from the ends of
the lines? The commands in \score are not behaving as I thought they would
based on the documentation.
Problem 2: How can I align the text markup to the start of the lines? I
want "No. 1" etc. left-aligned to the very start of the staff.
Extra query: Does anyone know why using \partial breaks the beaming in the
measure preceding the partial measure? Is there a general fix for this?
(Short of hard-coding the proper beaming with [ ].)
Any assistance gratefully received!

Chrome iOS - Loading indicator when applying class with jQuery
Chrome iOS - Loading indicator when applying class with jQuery
For some reason, my page displays the loading indicator on Chrome, when
applying a class to a section with css transition. I think this is causing
the address bar to be 'active', and won't slide up again. And thus
covering my navigation bar. I'm using iPhone 4, iOS5.
I've tried to pin-point what might be causing this, because it's not there
on desktop Chrome, or on Safari on the iphone. The page has a google map,
and I'm collecting data from an XML document using $.ajax. This is however
not causing the problem, cause I've tried disabling everything in the
js-file, except the click handler that applies the class.
Here's the CSS:
#main_bottom {
position: absolute;
bottom: -297px;
width: 300%;
height: 384px;
background-color: #ececec;
-webkit-transition-property: bottom, left;
-webkit-transition-duration: 0.2s;
}
#main_bottom.active {
bottom: 36px;
}
I'm using this to apply the class:
$(document).on('click', '#main_bottom > section:not(#gps) > a', function (e){
e.preventDefault();
$($main_bottom).toggleClass('active');
});
What could be causing this? It seems to be related to the animation
somehow, not sure why. Could it be the absolute positioning, along with
the css transition? If I'm allowed to link to the current live site, I'd
be happy to do that :)

I'm developing an application which has a view of only one card and
everytime this card is clicked the card shows a random card from the deck.
I already implemented a deck class which has drawRandomCard method which
draws a random card
@interface Deck()
@property (strong,nonatomic) NSMutableArray *cards; //of Card
@end
@implementation Deck
- (NSMutableArray *)cards
{
if(!_cards){

Are cookies secure from local access on the user's computer?
The book says "When a user visits a website, the browser locates and

Is this really true. I mean cookies is just text files without any type of

iOS- Cannot get expected json results back
iOS- Cannot get expected json results back
I am trying to use google currency rest api to get USD->GBP convert
result. something like this->
http://www.google.com/ig/calculator?hl=en&q=100USD=?GBP
the json is response is :
{lhs: "100 U.S. dollars",rhs: "62.9802242 British pounds",error: "",icc:
true}
so i m trying to get the values from "lhs" "rhs" stored into 2 strings
here is my method for fetching converted result data :
@implementation ConvertorBrain
-(id)initWithFromCurrency:(NSString *)fromCurrency
toCurrency:(NSString *)toCurrency
withAmount:(int)amount
{
if (self=[super init]) {
self.fromCurrency = fromCurrency;
self.toCurrency = toCurrency;
self.amount = amount;
}
return self;
}
-(void)getConvertResult

} else {
[[[UIAlertView alloc] initWithTitle:@"Service Error"
message:@"Cannot complete your request at this time, please try
later" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]
show];
}
}
then i called method in some other place like this :
self.brain = [[ConvertorBrain alloc] initWithFromCurrency:@"USD"
toCurrency:@"GBP" withAmount:100];
[self.brain getConvertResult];
then my expected lhs and rhs results should be lhs= "100 U.S. dollars" rhs
="62.9802242 British pounds"
however, if i run the code, it throw me back these errors: Error

it a bit. it seems is this line went wrong, dosent get any data somehow ->

Populating user data with facebook AFTER the user signed up with their email address
Populating user data with facebook AFTER the user signed up with their
email address
I'm sure there is a feasible solution to this problem but I couldn't find
it so far. In my application,I only want to let users with the certain
email account(such as gmail etc.) for now. Once the user verified their
email, I want to create a populate with Facebook button at the bottom of
my view that will only used once, and it will disappear once the person
populates information from it. I am planning to place this button at the
button of the profile view view controller here. I have a login/sign up
implementation using parse.com as backend and after sign in, user directly
goes to this view. If anyone knows the solution to this, I would
appreciate the help. Thank you!

Saving HTTP_REFERER in django
Saving HTTP_REFERER in django
I have the following code in Django:
def signup(request)
http_referer = request.META.get('HTTP_REFERER','/')
if request.user.is_authenticated():
return HttpResponseRedirect(reverse('index'))
else:
if request.method == 'GET':
# return HttpResponse(http_referer) Here it returns the right
value
args={}
return render(request,'signup.html',args)
elif request.method =='POST':
# return HttpResponse(http_referer) Here it breaks and returns
current url
... actual code goes here, but this should be enough
I want to save the HTTP_REFERER for later use, because it is being
changed. I have tried storing it in variable, but somehow variable still
automaticlly changes. I guess i could try storing it temporarily in
database (it probably won't change there), but since I only need it in
that function and never again, that seems like a bad solution. Is there a
better way of doing this?

execute mysql query and display results while reading
execute mysql query and display results while reading
I have a mysql database and i want to execute a query and while this query
is being executed the data should be displayed in page.
so for example if i have 1,000 result row from the query result i want to
display each row while the query is being executed instead of waiting till
the query finishes executing then displaying them at once.
here is my php code:
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
// Database Name
mysql_select_db("dbname", $con);
$test_query = mysql_query("SELECT * FROM V_Posts where _PID > 100 and _PID
< 10000");
while($CHECK_PCID_R = mysql_fetch_array($test_query))
{
echo $CHECK_PCID_R['_PID'] . "<br />";
}
?>
I tried
echo $CHECK_PCID_R['_PID'] . "<br />";
flush();
But it didn't work :(

I am trying to create a very simple java Applet to try out using Java
functions in a web browser. problem is, is that I can't get any sort of
functionality from my applet. I've tried dozens of tutorials and answers
from within this site, but nothing produces any different result, The
browser always says AppName.FunctionName is not a function.
Here is my html...

var elem= document.getElementById('AppTest');
alert(elem);
elem.test();
alert("Attempt 2");
document.AppTest.test();
}

and here is my Java code...

finding which div was clicked when click event is on class
finding which div was clicked when click event is on class
I have multiple divs under class subcat. And I have a click event on the
class. I want to get the div which was clicked.
<div class="subcat"><a href="#">abc</div>
<div class="subcat"><a href="#">def</div>
<div class="subcat"><a href="#">ghi</div>
<div class="subcat"><a href="#">jkl</div>
My jquery function is like
$('.subcat').click(function(element) {
element.preventDefault();
getsubcat(element);
});
But the element shows null. I tried using this instead of element but that
didn't work either.
$('.subcat').click(function(element) {
this.preventDefault();
getsubcat(this);
});
I had earlier written it as below and it was working perfectly well.

Inscribing Square within Circle
Inscribing Square within Circle
This is my second programming homework assignment this semester and I am
totally new to the concept of java programming. I was looking to see if
anyone could give me some advice on my code because I'm really confused
right now. Here's what I have so far:
I can get it to work a little, but the given values have to be around 500
and the inscribed circle that is drawn isn't in the right location. If
anyone could help I would really appreciate it. My main question is
regarding the fact that I'm able to print my circle inside my square with
no problems but when I try to print the inscribed circle using the offset
as my graphical coordinates the drawing comes out skewed to the right. If
anyone could review code and offer me some advice that would be highly
appreciated.

Simple way to run two while loops at the same time using threading?
Simple way to run two while loops at the same time using threading?
I have looked through all the previous answers, and they are all too
complicated for a beginner like me. I want to run too while loops at the
same time. For example, I want to run these two at the same time:
def firstFunction():
do things
def secondFunction():
do some other things
As I said, the other answers are too complex for me to understand.

I am passing values from PHP Script to JS using JSON encode.
$arr=array('X'=>$X,'Y'=>$Y,'par'=>$par);

Which produces

But I am not able to obtain the values of X alone. I tried few suggestions
from similar threads, but none of them did the trick.I need the three

Thread-safety in C#
Thread-safety in C#
I have currently been assigned a project that was implemented couple of
years ago in C#. It consists of frames and some excel-files extraction,
but the problem is that this project is extremly broken/outdated and I
have to change some functionalities and add some new feature.
There are some libraries that are supported only after .NET framework 3.0
that I need to use in the new features,and the framework that the current
project was built on is 2.0 or less,so changing the framework raised some
thread safety problems.
Between two partial classes for example which are the design file code and
the backend code trying to change one label's value raises an error saying
that I can not edit something that is being used at the moment... I used
delegates for one of the labels, and it worked fine..then the other
textbox raised another error.. So is there an option to encapsulate the
whole thing and apply thread safety to the whole code without having to
follow each line where the error happens?
Regards

Validation of a geometry in WKT format
Validation of a geometry in WKT format
I am new to GIS area and I need to validate a geometry in WKT format in
java, to check whether a simple polygon is a closed loop, i.e the start
and end points of the vertices should be the same. I am currently using
jGeometry class of oracle spatial(com.oracle.sdoapi), get the first and
last vertices and comparing them. also, i am using getType() method to
check whether it is a simple polygon or not. The following is the piece of
code that am using:
WKT wkt = new WKT();
JGeometry geometry = wkt.toJGeometry(wkt.getBytes());
double[] d1 = geometry.getFirstPoint();
double[] d2 = geometry.getLastPoint();
if(!jGeometry.getType() == jGeometry.GTYPE_POLYGON){
//error message for other geometries
}
Is there any simple way of doing this or is there any API available? I
dont want to reinvent the wheel, if it is already done and simple to use.
Thanks!

What more does the code need to delete a node from a linked list successfully?
What more does the code need to delete a node from a linked list
successfully?
I want to delete a given node from a linked list by the node's index
number (serial number). So what I tried to do in my function is that,
first I have taken the user input of the index number. Then I used two
node type pointers temp and current. I started traversing the list with
current and when the index number of the node matches with the user input,
I tried to delete the node. So far it is correct. I am facing problem with
the deletion logic. Here is the code I tried:
void delete_node(struct node **start,int index_no)
{
int counter=0;
struct node *temp, *current;
temp=(struct node *)malloc(sizeof(struct node));
current=(struct node *)malloc(sizeof(struct node));
current=*start;
while(current->next!=NULL)
{
counter++;
if(counter==index_no)
{
temp= current->next;
free(current);
/*I guess some code is missing here. Help me finding the logic.*/
}
else
{
printf("\n The index number is invalid!!");
}
}
}
The commented portion lacks the deletion logic. Also, I have a feeling
that this code is not space and time-efficient. If it is so, please
suggest to a way to make it more compact.

the countdowns. The starting time seems to be a little different on
different machines (usually a discrepancy of about a second, but sometimes
2 or 3), which obviously is a big issue for bidders. I'm thinking a big
part of the answer is simply network lag, but (a) are there other factors
involved? and (b) is there a way to correct for network lag somehow?
I've tried hitting the server via an Ajax call every second, and that
works well enough (though there's always a bit of lag) but I'd rather not
have to do that because it'll be hard on the server.
JavaScript development is not my forte, so I'd appreciate any tips and
feedback!
Here's my code, as generated on the server
jQuery(document).ready(function() {
var aid = " . $aid . ";
var loadTime = Math.floor(jQuery.now()/1000);
//alert(loadTime);
serverTime = " . time() . ";
var clockDiff = loadTime - serverTime;
var diff;
auctionExpirationValue" . $aid . " = " . $expiry . ";
var newServerTime = setInterval(function() {
diff = window['auctionExpirationValue' + aid] -
Math.floor((jQuery.now())/1000) + clockDiff;
diff_string = parse_countdown(diff);
jQuery('#auction-expiry').html(diff_string);
},1000);
});
the clockDiff variable is to account for any clock differences between the
user's machine and the server. Obviously, if one machine is ahead or
behind the user would see different values in the countdown.
As you can see, the code loops every second (or, more or less every
second, I understand it's not exact), calculates the difference between
now and the auction expiry (compensating with clockDiff), formats it and
displays it. Pretty simple. The auctionExpirationValue*** global variable
is used to store the auction expiry time locally as a timestamp.
My client has also informed me that on his iPad, the countdown would
sometimes drift a little, in addition to the original discrepancy. What's
the explanation there?
