DNS Server, DHCP Client and Server works fine, but request time out occurs
when using MikroTik as an access point for a modem
I use 2 Mikrotik wireless router, the first one is connected to modem and
it works perfectly (SSID: server-one (hidden)).
Second router ID:
ether1: 192.168.1.1
wlan1: dhcp-client
wlan2: 192.168.2.1
SSID: skywifi
Then, i tried to configure the second router. I set wlan1 to connect to
server-one, as a station and dhcp client and received 192.168.50.124 as
its IP, 192.168.50.254 as its gateway.
I set wlan2 as an ap-bridge, and set it as dhcp server. Then I create a
static route to 0.0.0.0/0 through 192.168.50.254.
Connection OK, DNS to device connecting skywifi works perfectly, i can
nslookup google.com. The problem is, when i tried to ping google.com, it
always give request time out reply. (Note that I also tried to ping
another host too (Wikipedia,Yahoo, etc). The result is also request time
out.
Any idea why this things happened? Thanks,

Fire a javascript function after jquery autosuggest selection made
Fire a javascript function after jquery autosuggest selection made
I have the jQuery autosuggest working. What i'd like to do though is after
the data is selected from the autosuggest, to be able to fire off a
javascript function. So the user selects the name John Smith and some
other info gets populated with ajax. I have the ajax working, I have the
autosuggest working but can't figure out how to get the autosuggest to
fire off the ajax.
I've tried putting a call in the select portion of the autosuggest.. that
didn't work. was almost as if it was getting ignored. Anyway.. I've looked
around and can't find the answer.
thanks for any help shannon

How to log the CPU and network utilization for Android
How to log the CPU and network utilization for Android
I want to get the CPU utilization over time and turn the records into plot
diagrams. I have surveyed some method for instant utilization, like shell
command top, dumpsys, and APPs TaskSpy.
Usage: top [ -m max_procs ] [ -n iterations ] [ -d delay ] [ -s
sort_column ] [ -t ] [ -h ]
-m num Maximum number of processes to display.
-n num Updates to show before exiting.
-d num Seconds to wait between updates.
-s col Column to sort by (cpu,vss,rss,thr).
-t Show threads instead of processes.
-h Display this help screen.
dumpsys
I want to customize the chart like TaskSpy and add some details to
analysis. It will be better to analysis on PC/MAC. Can I do these by adb
shell command?

A call to PInvoke function has unbalanced the stack
A call to PInvoke function has unbalanced the stack
Making a function call to .NET 4 to native code is resulting in the
following exception:
A call to PInvoke function has unbalanced the stack. This is likely
because the managed PInvoke signature does not match the unmanaged target
signature. Check that the calling convention and parameters of the PInvoke
signature match the target unmanaged signature.
Here is my definition in Native Code:
typedef void ( CALLBACK* CB_DOWNLOADING )
(
ULONG, // secs elapsed
LPARAM, // custom callback param
LPBOOL // abort?
);
FETCH_API HttpFetchW
(
LPCWSTR url,
IStream** retval,
LPCWSTR usrname = NULL,
LPCWSTR pwd = NULL,
BOOL unzip = TRUE,
CB_DOWNLOADING cb = NULL,
LPARAM cb_param = 0,
LPWSTR ctype = NULL,
ULONG ctypelen = 0
);
Here is the .NET counterpart:
[DllImport(dllPath, CharSet = CharSet.Unicode, SetLastError = true,

internal static extern FETCH HttpFetchW

How to implement double indexing in a 2D sparse scipy matrix?
How to implement double indexing in a 2D sparse scipy matrix?
Suppose I have a 2D sparse matrix M representing the results of 2-on-2
basketball matches. I want to use address the elements of the matrix using
double-indexing : Element M[i,j][k,l] will represent the score of the game
played by a team of players i and j against team k and l. Thus, each
column/row is specified by two numbers instead of one. Note that this is
not a 4D matrix. I'm looking for a way to do this with a sparse SciPy
matrix in order to be able to perform various matrix-related calculations
(eigenvalues/vectors, etc).

TreeView binding from XML by ID
TreeView binding from XML by ID
I'm using WPF.(MVVM pattern) I want to make hierarchical tree using
TreeView. Data from XML. But XML structure is not hierarchical actually.
Nodes binds by ID. XML looks like the following:
<root>
<node>
<Id>1</Id>
<ParentId>-1</ParentId>
<Name>ROOT</Name>
</node>
<node>
<Id>2</Id>
<ParentId>1</ParentId>
<Name>NODE</Name>
</node>
</root>
What should i use to do this? It will be great if you show me any simple
example.
And the second question. How can i get nodes dinamically? That is when i
run the application only root is loading.
Thanks in advance.

Use Python's `timeit` from a program but functioning the same way as the command line?
Use Python's `timeit` from a program but functioning the same way as the
command line?
For instance, documentation says:
Note however that timeit will automatically determine the number of
repetitions only when the command-line interface is used.
Is there a way to call it from within a Python script and have the number
of repetitions be determined automatically, with only the shortest number
returned?

Data Source SQL Command from Variable using default value instead of updated value
Data Source SQL Command from Variable using default value instead of
updated value
I have four dynamically assigned variables in my package. Each one is
populated using a query similar to this:
select 'SELECT * FROM SHARE_DM.MDM_ORG_CLASSIFICATIONS WHERE LAST_UPD_DATE
>= '''
+ (select convert(nvarchar(50), coalesce(max(last_upd_date),
cast('1/1/1900' as datetime)), 106) from MDM_ORG_CLASSIFICATIONS)
+ '''' sql
The default queries are defined like this:
SELECT * FROM SHARE_DM.MDM_ORG_CLASSIFICATIONS WHERE LAST_UPD_DATE >= '01
Jan 1900'
(I'm building the sql like this because I'm using Oracle data connections
and the parameter parsing doesn't work properly, where this technique has
worked before)
The output sql comes out like this:
SELECT * FROM SHARE_DM.MDM_ORG_CLASSIFICATIONS WHERE LAST_UPD_DATE >= '26
Sep 2013'
I have validated that my variables are being updated using message boxes
in script components. When I run the queries manually against Oracle, I
get very small result sets, as expected. However, when I run the package,
I get full result sets as if the default value of 1/1/1900 was being used
instead of the updated variable.
Each variable is set to EvaluateAsExpression False.
Comparing the operation in this package vs. a different package where I do
the same kind of operation, I'm not seeing any obvious differences -
except for one thing - in the other package I list each column in the
select statement, whereas in here I use select *.
Why isn't my OLE DB Source updating with the updated SQL from the variable?
Edit: Thinking maybe the select * was the issue, I updated one of them to
use explicit column names. No change.

select statement, whereas in here I use select *.
Why isn't my OLE DB Source updating with the updated SQL from the variable?
Edit: Thinking maybe the select * was the issue, I updated one of them to
use explicit column names. No change.

how can I check which submit button was pressed?
how can I check which submit button was pressed?
I have a two submit buttons set up for form submission. I'd like to know
which submit button was clicked without applying a .click() event to each
one. One more thing I am using ASP.NET MVC 3 and want to get the clicked
button name in Controller.
Here's the setup:
<a class="anchorbutton">
<input type="submit" value="Save" id="Save" class="hrbutton"/>
</a>
<input type="submit" value="Save & Next" id="SaveNext" class="hrbutton
anchorbutton"/>
$('#form').live('submit', function (e)
{
e.preventDefault();
var form = $('#form');
$.ajax({
cache: false,
async: true,
type: "POST",
url: form.attr('action'),
data: form.serialize(),
success: function (data) {
$.ajax({
url: 'url',
dataType: "html",
success: function (data) {
$("#div").html(data);
}
});

keep the first part and delete the rest on a specified line using sed
keep the first part and delete the rest on a specified line using sed
I know a line number in a file, wherein I want to keep the first word and
delete the rest till the end of the line. How do I do this using sed ? So
lets say, I want to go to line no 10 in a file, which looks like this -
goodword "blah blah"\
and what i want is
goodword
I have tried this - sed 's/([a-z])./\1/'
But this does it on all the lines in a file. I want it only on one
specified line.

"This version of JustMock has expired!" after purchasing a license
"This version of JustMock has expired!" after purchasing a license
I recently purchased a license for Telerik JustMock. The Telerik Control
Panel shows JustMock under my list of Purchased products. When I attempt
to run my tests in Visual Studio's Test Explorer with the JustMock Visual
Studio extension enabled I receive an exception saying:
Telerik.JustMockExpiredException : This version of JustMock has expired!
I have uninstalled all the Telerik Visual Studio extensions, uninstalled
everything Telerik via Windows Programs/Features, then re-installed the
control panel and then JustMock yet the problem persists. Of note, when I
re-installed the control panel it remembered my username/password so I'm
guessing there is a configuration file somewhere caching my information
incorrectly.
A possible root cause of this problem is that I was trialing JustMock
under my personal email address but it was purchased by my company and
assigned to my work email address. I am currently logging into the control
panel with my work address and see no other place to change that.

NullPointerException when trying to send a message to a Client Socket
NullPointerException when trying to send a message to a Client Socket
I have a ServerHandler class, which creates a new PrintWriter and stores
it into a PrintWriter array, The message gets sent by giving the
selectedId integer the ID number of the client that should receive the
message. When i call the SendMessage() method inside the ServerHandler
class it sends the message without a problem, but when i try to call the
SendMessage("some message") method from the class that contains the GUI it
gives me a NullPointerException.
The posljiSporocilo() is the actual SendMessage() because some methods are
in my language
import java.net.*;
import java.io.*;
import java.awt.*;
public class ServerHandler implements Runnable{
Socket klientSocket;

writer = new PrintWriter(this.klientSocket.getOutputStream());
writerHolder[userCounter] = writer;
InputStreamReader inReader = new
InputStreamReader(this.klientSocket.getInputStream());
reader = new BufferedReader(inReader);
out.frameOutput(this.klientSocket.getInetAddress().toString(), "Server
sprejel povezavo:");

When i call the posljiSporocilo() method in the actual class it does send
the message to the Client.

Passing calculation result to JSP page
Passing calculation result to JSP page
Index.jsp takes two input number and after submit the request go to
Operation.java. It has a radio button to select Operation. Both inputs and
radio button are submitted to Operation.java.
<form action="Operation">
First number::<input type="text" name="firstno"></input>
Second number::<input type="text" name="Secondno"></input>
<input type="radio" name="option" value="add">Add</input>
<input type="radio" name="option" value="substract">Subtract</input>
<input type="radio" name="option" value="mul">Multiply</input>
<input type="radio" name="option" value="divide">Divide</input>
<input type="submit" value="submit">
</form>
Operation.java(Servlet) takes value from input button and do calculation
based on the radio button click. It will calculate the result.
int result1=0;
int n1=Integer.parseInt(request.getParameter("firstno"));
int n2=Integer.parseInt(request.getParameter("Secondno"));
String radio=request.getParameter("option");
if(radio.equals("add"))
{
result1=n1+n2;
}
else if(radio.equals("substract"))
{
result1=n1-n2;
}
else if(radio.equals("mul"))
{
result1=n1*n2;
}
After calculation I want to show the result on the index.jsp. How can I do
that?

I've already created a database using code first. It worked well. Many
changes have since been made to the database outside Visual Studio. So
many that any attempt at migration generates errors. So my question is, is
there a way to switch a solution from code first to database first?

Call function directly after constructor: new Object()->callFunction()
Call function directly after constructor: new Object()->callFunction()
As you might have seen in the title, my programming background is Java. In
Java you can do stuff like this
new Object().callSomeMethod();
without assigning the created Object to a variable, very useful and clear
coding if you only need this Object once.
Now in PHP i try to do the same
new Object()->callSomeMethod();
but here i get a 'Parse error: syntax error, unexpected '->'
(T_OBJECT_OPERATOR)'.
Is there a way to do this in PHP ?

Use custom powershell module in C#
Use custom powershell module in C#
I wrote fuction PowerShell module like that:
Function docConvert2{
param ([string]$sourceFile, [string]$sourceFilePath)
....
....
}
I've imported module successfuly
And i can use module in powershell cmdlet
When i try call function in c#, i got exception like that
The term 'docConvert2' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and try
again.
C# code
PowerShell pShell = PowerShell.Create();
pShell.AddCommand("docConvert2");
pShell.AddParameter("sourceFile", "'addendum no-3_PREP.doc'");
pShell.AddParameter("sourceFilePath", @"'D:\New\wordler'");
pShell.Invoke();
What is my mistake?
Thanks for advices.

Ajax - Lazy load random elements without repeating
Ajax - Lazy load random elements without repeating
I have a database of, lets say 10,000 records. I have a webpage where I
want to display each record in a list, in random order. Because there are
so many records, I want to initially load only 100 records on the page,
and as you get to the bottom of the page, another 100 is added via AJAX,
then as you scroll to the bottom, 100 more, etc...
The trick is that overall, I want the order of the displayed records to be
random, but also, they cannot repeat. So just doing an AJAX call to pull
in 100 random records isn't going to work since some of those records may
have already been displayed on the page.
Is there a certain trick to doing this?
I was thinking maybe keeping track of the record id's that have been
displayed already and sending this in the AJAX call and then fetch 100
random records who's ID's have not already been displayed... But I'm
afraid for a high traffic website, this would get pretty slow as you can't
cache that too easily, without recreating the same thing using cached
arrays.
What is the best approach to this?

Customer view for Team Foundation Service
Customer view for Team Foundation Service
My team recently migrated from onsite to the cloud Team Foundation Service
2012.
We had also maintained a separate SharePoint portal with extranet
capabilities to list projects/tasks etc. for external customers
Seeing that we're now online, I was wondering if there is a means to
restrict a view to PBIs/Certain properties of tasks [Time Elapsed, Time
Remaining] for certain accounts.
Alternatively, I recall seeing SSRS capabilities in the on site version.
Is there a means to configure reports (scheduled/manual) using the Team
Foundation Service?

Is there a way to determine if a parameter is a literal string?

My question is:
Is there a way to determine whether a parameter is a literal string or not?
template<class T>
bool IsLiteral(T arg)
{
// How to implement?
}
or
template<class T>
struct IsLiteral { enum { value = ??? }; };
So that we can write the following code:
char* p = "Hello";
assert(IsLiteral(p)); // fail.
assert(IsLiteral("Hello")); // never fail.

CheckBox in C# Windows App

I have 3 checkboxes and I am able to turn two of them off if one is
checked. But I want that if the 3rd one is checked then the first two
should be turned off. how can I do that?
This is what I am trying.
private void chkResFoodVeg_CheckedChanged(object sender, EventArgs e)
{
//disables the other checkbox if one is checked
this.chkResFoodNveg.Enabled = !this.chkResFoodVeg.Checked;
}

}

{
this.chkResFoodBoth.Enabled = !this.chkResFoodNveg.Checked &&
!this.chkResFoodVeg.Checked;
}
The last part of code doesn't work. It should turn off the first two
checkboxes.
Thanks

Is there a way to control thread count, affinity and creation time in Intels Threading Building Blocks?
Is there a way to control thread count, affinity and creation time in
Intels Threading Building Blocks?
Currently I use Intels TBB to parallelize some work using
tbb::parallel_for. It seems that the amount of threads and the point in
time when they are started is controlled by TBB in the background. Looking
through the User Guide and Reference Documentation I could not find any
hint on whether there are any control options or modules. I would like to
be able to modify the amount of threads and, if possible, decide when the
thread pool is created.

UICollectionView Cells and Rasterizing
UICollectionView Cells and Rasterizing
I recentlty discovered that by adding this before returning my collection
view cell improves scrolling animation performance (smoothness).
cell.layer.shouldRasterize = YES;
cell.layer.rasterizationScale = [UIScreen mainScreen].scale;
If my cell contains, multiple buttons do I need to rasterize those
individually, or will that be taken care of automatically?... or should I
ever bother?
I have added the buttons via Interface Builder.

substring dynamic number of characters

Does mysql have an IF functionality to determine the number of characters

CSS navigation issues and image sound
CSS navigation issues and image sound
I'm currently working on a site which is very basic. and its has 2 issues.
I've uploaded my site. which is being edited until its fully working. The
intro page works fine which is the index. html page. Then second I click
on my sites menu bar for HOME it loads home. While on HOME I want to go to
INTRO. To see if the link works. instead loading intro page as it does
when I load site for first time. It loads the WEBHOST site page? Can
anyone pass on any clues as to why this happens.
Also my second question is when putting together my profiles page together
of the cast of the A-TEAM show. With images on left column underneath each
other running down page and text on right same way as pictures. I want
each image to be clicked on to play the sound. I don't want no in browser
players or anything else. just click image play sound. were do I put the
code and can how I make it work for the 5 images that need audio linked to
them?

Another class interacting with variables in main method
Another class interacting with variables in main method
I have a main method which creates a List<Long>. I then have another class
whose state is a List<Long> - the goal of this class is to take in the
main method's List<Long> as its state and do manipulations to it without
affecting the main method's List<Long>.
However the problem that I am facing is that this other class is impact
both its state (its private List<Long>) as well as the List<Long> in the
main method.
How do I adjust my code such that setTesting(...) is only able to
influence the state of its class?
public class Main {
public static void main(String[] args) {
final List<Long> mainlist = new ArrayList<Long>();
mainlist.add((long) 1);
mainlist.add((long) 2);
mainlist.add((long) 3);
Test testlist = new Test();
testlist.setTesting(mainlist);
System.out.println(testlist.getTesting());
testlist.removal((long) 1);
System.out.println(testlist.getTesting());
}
}
public class Test {
private List<Long> testing = new ArrayList<Long>();
public Test() {
}
public void removal(Long remove) {
this.testing.removeAll(Collections.singleton(remove));
}
public void setTesting(List<Long> list) {
this.testing = list;
}
public List<Long> getTesting() {
return this.testing;
}
}

Unicode null and JSON
Unicode null and JSON
I have a JSON object that when serialized gets the null Unicode character.
(The character is coming from a database.) I can replace the character
through java but it seems slightly hackish to look for a specific
character to fix. So I'm wondering if there's a way I can do it by just
changing the encoding. It's currently being encoded using UTF-8. Any
thoughts?

Glimpse shows Duplicate EF queries
Glimpse shows Duplicate EF queries
I'm having problems with my MVC 4 application running too slowly. I
installed Glimpse to profile the application. I think I've found part of
the problem: many of my EF queries appear to be running twice! Here's my
HomeController that is pulling some alerts:
[HttpGet]
public virtual ActionResult Index()
{
var reportStart = DateTime.Today;
var reportEnd = DateTime.Today.AddMonths(1);
var query = _tameUow.Alerts
.FindBy(a => a.ApprovalStatusId ==
(int)AlertApprovalStatusCodes.Approved &&
(a.ScheduledStartDateTime >=
reportStart &&
a.ScheduledStartDateTime <=
reportEnd), a => a.SubmittedBy, a =>
a.ApprovalManager, a =>
a.ApprovalStatus);
var model = ListAlertsViewModelBuilder.Build(query, null, false,
false, false, false);
model.RequiredViewData = new RequiredViewDataModel("Upcoming
Alerts", "These are the upcoming active alerts for the next
month.", "Home");
return View(model);
}
But when I view the SQL tab in glimpse, it shows the query twice! At first
I thought it was just a bug and the same query was being displayed twice,
but they have different execution times, so I think that the query is
actually being run twice! Also, the little yellow exclamation mark shows
up as a warning. I THINK this is warning me that it is a duplicate
query...
http://i.imgur.com/jizQwKz.png What's going on here? I see this on all
the pages I've tested, I chose this one as an example because it is the
simplest. I tried setting a breakpoint on the query, and it is only being
hit once.
Here's the VMBuilder:
public static class ListAlertsViewModelBuilder
{
public static ListAlertsViewModel Build
(IQueryable<Alert> query
, string curUserExtId
, bool showSubmittedDateTime
, bool showStatus
, bool showActions
, bool showOwners)
{
var model = new ListAlertsViewModel();
var alerts = query.Select(a => new AlertDetailsViewModel() {
AlertId = (int)a.AlertId,
ApprovalManager = a.ApprovalManager,
ApprovalManagerExtId = a.ApprovalManagerExtId,
ApprovalStatus = a.ApprovalStatus,
ApprovalStatusId = (int)a.ApprovalStatusId,
Building = a.Building,
Cause = a.Cause,
//Comments = a.Comments,
Impact = a.Impact,
ScheduledEndDateTime = a.ScheduledEndDateTime,
ScheduledStartDateTime = a.ScheduledStartDateTime,
Service = a.Service,
SubmittedBy = a.SubmittedBy,
SubmittedByExtId = a.SubmittedByExtId,
SubmittedDateTime = a.SubmittedDateTime,
CurrentUserExtId = curUserExtId
});
model.ListAlerts = alerts;
model.ShowSubmittedDateTime = showSubmittedDateTime;
model.ShowStatus = showStatus;
model.ShowActions = showActions;
model.ShowOwners = showOwners;
return model;
}
}
And this is the FindBy method I'm using from my repository:
public IQueryable<T> FindBy(Expression<Func<T, bool>> predicate, params
Expression<Func<T, object>>[] includeProperties)
{
IQueryable<T> query = this.Context.Set<T>();
foreach (var include in includeProperties)
{
query.Include(include);
}
return query.Where(predicate);
}
I'm having problems with my MVC 4 application running too slowly. I
installed Glimpse to profile the application. I think I've found part of
the problem: many of my EF queries appear to be running twice! Here's my
HomeController that is pulling some alerts:
[HttpGet]
public virtual ActionResult Index()
{
var reportStart = DateTime.Today;
var reportEnd = DateTime.Today.AddMonths(1);
var query = _tameUow.Alerts
.FindBy(a => a.ApprovalStatusId ==
(int)AlertApprovalStatusCodes.Approved &&
(a.ScheduledStartDateTime >=
reportStart &&
a.ScheduledStartDateTime <=
reportEnd), a => a.SubmittedBy, a =>
a.ApprovalManager, a =>
a.ApprovalStatus);
var model = ListAlertsViewModelBuilder.Build(query, null, false,
false, false, false);
model.RequiredViewData = new RequiredViewDataModel("Upcoming
Alerts", "These are the upcoming active alerts for the next
month.", "Home");
return View(model);
}
But when I view the SQL tab in glimpse, it shows the query twice! At first
I thought it was just a bug and the same query was being displayed twice,
but they have different execution times, so I think that the query is
actually being run twice! Also, the little yellow exclamation mark shows
up as a warning. I THINK this is warning me that it is a duplicate

Trouble setting ubuntu vhost file
Trouble setting ubuntu vhost file
Ok. I'm trying to set my config files in ubuntu.
When I look in the sites-available folder, I see
000-default.conf ssl-default.conf
I have a site testsite.com that I need to configure the vhost for https
1) Can I just add a new vhost section to ssl-default.conf? Should I copy
the entire file to testsite.conf and make my edits there? 2) Where should
I put the set up for port 80? 000-default.conf? if I copy the file, do I
need to add the 000 to the file name so that it is read first? 3) where
can I put the info that used to be in the default file ie( allow
overrides, etc)
Thank you

what the correct syntax is when comparing multiple strings
$(document).ready(function() {

PayPal Java NVP API GetExpressCheckoutDetails - Missing Data
PayPal Java NVP API GetExpressCheckoutDetails - Missing Data
I'm calling the PayPal sandbox with a 'express checkout' process from a
java web application. The first call ('SetExpressCheckout') succeeds and I
receive a Token as expected.
The second call ('GetExpressCheckoutDetails') succeeds as well in regard
to getting an ACK=Success answer. But there is all the payer information
data like FIRSTNAME, LASTNAME or SHIPTOCITY missing.
Here's the URL I'm calling with parameters:
https://api-3t.sandbox.paypal.com:443/nvp?TOKEN=__MY_TOKEN__&VERSION=106.0&SIGNATURE=__MY_SIGNATURE__&METHOD=GetExpressCheckoutDetails&PWD=__MY_PASSWORD__&USER=__MY_USERNAME__
Here's the response's body I get:
TOKEN=__MY_TOKEN__&CHECKOUTSTATUS=PaymentActionNotInitiated&TIMESTAMP=2013%2d09%2d11T20%3a56%3a36Z&CORRELATIONID=bb3916c14aa78&ACK=Success&VERSION=106%2e0&BUILD=7645184&CURRENCYCODE=USD&AMT=12%2e00&SHIPPINGAMT=0%2e00&HANDLINGAMT=0%2e00&TAXAMT=0%2e00&INSURANCEAMT=0%2e00&SHIPDISCAMT=0%2e00&PAYMENTREQUEST_0_CURRENCYCODE=USD&PAYMENTREQUEST_0_AMT=12%2e00&PAYMENTREQUEST_0_SHIPPINGAMT=0%2e00&PAYMENTREQUEST_0_HANDLINGAMT=0%2e00&PAYMENTREQUEST_0_TAXAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEAMT=0%2e00&PAYMENTREQUEST_0_SHIPDISCAMT=0%2e00&PAYMENTREQUEST_0_INSURANCEOPTIONOFFERED=false&PAYMENTREQUEST_0_ADDRESSNORMALIZATIONSTATUS=None&PAYMENTREQUESTINFO_0_ERRORCODE=0
If I put the same request URL into Firefox I receive the response I would
expect:

I tried calling the PayPal sandbox from java using

I tried running the webapp in JBoss 7.1.1 on mac OS X and JBoss 7.2.0 on

The result is always the same. The payer information (name, address) is
missing when I call it from java.

Continuously write to TCP socket without reading
Continuously write to TCP socket without reading
I have a TCP client server application written on boost 1.53. Based on the
client command I have to start a server thread to write some data to a
socket. But I have no guarantee that the client application would start
reading from this socket. Is there any trouble writing data to a socket
without reading from it? Won't be there any socket overflow or data
corruption ?
Looking forward to hearing your ideas.
Thx, Dmitry

Zoom in an image with out loosing text resolution
Zoom in an image with out loosing text resolution
I want to implement an application like "The star Epaper" available on
Android and Apple Markets. This app is pretty amazing: it uses an small
images but if u pinch this image, the quality of texts never change. It
means by zoom in or zoom out the quality of image is still same. I went to
files of app and found that there is a jpg image ( i.e. 183 KB) and each
image has another file "22 KB" with no-extension. I used openwith and
found that this file is also an image. Therefore, This app is using both
of these images ( maybe one of the is vector) to replace the good quality
for text file whenever pinch event fired.
What is this technique ? and how to implement it?

HttpServlet Request in method remoted by DWR
HttpServlet Request in method remoted by DWR
I have a Following JSP:
<form action="UploadServlet" method="post"
enctype="multipart/form-data">
Select file to upload: <input type="file" name="file" id
=upfile"size="50" /> <input type="button" value="Save"
onclick="javascript:uploadPartnerDetails();" class="buttons">
</form>
And DWR Script which calls remoted Java Method:
function uploadPartnerDetails() {
SMUDWR.uploadPartnerDetails(function(data) {
dwr.util.setValue("UserTypeDiv", data, {
escapeHtml: false
});
});
}
The Remoted Method uploadPartnerDetails()is:
try {
WebContext wctx = WebContextFactory.get();
HttpServletRequest request = wctx.getHttpServletRequest();
// checks if the request actually contains upload file
if (!ServletFileUpload.isMultipartContent(request)) {
// if not, we stop here
}
The Problem is the request above does not contain multipart/form-data. How
to I get that from this request?

=upfile"size="50" /> <input type="button" value="Save"
onclick="javascript:uploadPartnerDetails();" class="buttons">
</form>
And DWR Script which calls remoted Java Method:
function uploadPartnerDetails() {
SMUDWR.uploadPartnerDetails(function(data) {
dwr.util.setValue("UserTypeDiv", data, {
escapeHtml: false
});
});
}
The Remoted Method uploadPartnerDetails()is:
try {
WebContext wctx = WebContextFactory.get();
HttpServletRequest request = wctx.getHttpServletRequest();
// checks if the request actually contains upload file
if (!ServletFileUpload.isMultipartContent(request)) {
// if not, we stop here
}
The Problem is the request above does not contain multipart/form-data. How
to I get that from this request?
Can Spring, JdbcTemplate not use Columns not specified in the Select List?
Can Spring, JdbcTemplate not use Columns not specified in the Select List?
I'm learning spring.
I can execute this query fine in MySQL (of course):
SELECT notes, month(dt) month, dayofmonth(dt) day, hour(dt) hour,
minute(dt) minute,
avg(temperature2) temperature2, avg(temperature) temperature,
avg(temperature1) temperature1
FROM temperature WHERE dt > curdate() - 1
GROUP BY notes, month(dt), dayofmonth(dt), hour(dt), minute(dt)
ORDER BY dt DESC
Python can do this fine.
Just using plain old Jdbc works:
Connection conn = null ;
try {
System.out.println("Start try");
String driver = "com.mysql.jdbc.Driver";
Class.forName(driver).newInstance();
conn =
DriverManager.getConnection("jdbc:mysql://localhost:3306/brew",
"root", "");
String sql = "SELECT notes, month(dt) month, dayofmonth(dt) day,
hour(dt) hour, "
+ "minute(dt) minute, avg(temperature2) temperature2,
avg(temperature) temperature, "
+ "avg(temperature1) temperature1, "
+ "FROM temperature WHERE dt > curdate() - 1 "
+ "GROUP BY notes, month(dt), dayofmonth(dt), hour(dt),
minute(dt) "
+ "ORDER BY dt DESC ";
PreparedStatement ps = conn.prepareStatement(sql) ;
ResultSet rs = ps.executeQuery();
if (rs.next()) {
System.out.println(rs.getString("notes") + " " +
rs.getDouble("temperature"));
} else {
System.out.println("No results");
}
rs.close();
ps.close();
But not JdbcTemplate in Spring?
public List<Temperature> getMinutelyTemperatures() {
String sql = "SELECT notes, month(dt) month, dayofmonth(dt) day,
hour(dt) hour, "

avg(temperature) temperature, "
+ "avg(temperature1) temperature1, "
+ "FROM temperature WHERE dt > curdate() - 1 "
+ "GROUP BY notes, month(dt), dayofmonth(dt), hour(dt),
minute(dt) "
+ "ORDER BY dt DESC ";
//return namedParameterJdbcTemplate.query(sql, new
MapSqlParameterSource(), new TemperatureMapper());
return jdbcTemplate.query(sql, new TemperatureMapper());
}
private static final class TemperatureMapper implements
RowMapper<Temperature> {
@Override
public Temperature mapRow(ResultSet resultSet, int rowNum) throws
SQLException {
Temperature temperature = new Temperature();
temperature.setNotes(resultSet.getString("notes"));
temperature.setDt(resultSet.getDate("dt"));
temperature.setTemperature(resultSet.getDouble("temperature"));
temperature.setTemperature1(resultSet.getDouble("temperature1"));
temperature.setTemperature2(resultSet.getDouble("temperature2"));
return temperature;
}
}
And I can't even use a column from a subquery to order on ?
public List<Temperature> getMinutelyTemperatures() {
String sql = "SELECT notes, month(dt) month, dayofmonth(dt) day,
hour(dt) hour, "
+ "minute(dt) minute, avg(temperature2) temperature2,
avg(temperature) temperature, "
+ "avg(temperature1) temperature1 "
+ "FROM (SELECT notes, dt, temperature2, temperature,
temperature1 FROM temperature WHERE dt > curdate() - 1) b "
+ "GROUP BY notes, month(dt), dayofmonth(dt), hour(dt),
minute(dt) "
+ "ORDER BY b.dt DESC ";
//return namedParameterJdbcTemplate.query(sql, new
MapSqlParameterSource(), new TemperatureMapper());
return jdbcTemplate.query(sql, new TemperatureMapper());
}
What am I overlooking here?
Here is the error:
nested exception is java.sql.SQLException: Column 'dt' not found.
If I just remove it from the order by clause, or just remove it from the
where clause, I receive the same error. I need to remove it from both or
place it in the select list (which requires aggregating on it--not want I
want to do)
