REACT this.props.history.push does not redirect
|
<p>I've got this search method where I want to redirect the user after searching. The issue is that it does not do anything and I don't know why. this.props.history IS defined but the "location" property of the object "history" does not seem to change accordingly to what i put in the parameters of the push method ('./connexion') ... The search method IS binded and I use <code>export default withRouter(SearchBar);</code> to access the history via props</p>
<pre><code> search(event) {
if (this.state.location === null) {
this.setState({ geosuggestId: 'geosuggest-input-alert' });
} else if (this.state.subjects.length === 0) {
this.setState({ matieresButtonId: 'matieres-button-alert' });
} else {
console.log(this.props.parent);
if (this.props.parent === 'Homepage') {
console.log(this.props.history);
this.props.history.push('/connexion');

c++ how-to: import numeric variables from .txt or .csv file
|
<p>still being a beginner at C++, I cannot figure out how to use <code>fstream</code>.
I want to assign values to a set of <code>double</code> variables in my program, from
a <code>.txt</code> or a <code>.csv</code> file (<code>.csv</code> might be better for practical reasons.)</p>
<p>Let's say that my <code>input_file.csv</code> looks like that:</p>
<pre><code>10
0
20
0.4
0.1333382222
0
0.5
10
20
0.76
0.3
0.1
0.2
</code></pre>
<p>These values should be assigned to the following variables (first declared as equal to <code>0</code> ) in my code:</p>
<pre><code>/// geometry
double Dist=0; ///Distance between the 2
double PosAi = 0;
double PosAo = 0;
double PosBi = 0;
double PosBo = 0; ///positions i/o
/// densities
double iDA=0;
double oDA=0;
double iDAtop=0;
double oDAtop=0; /// Left
double iDB=0;
double oDB=0;
double iDBtop=0;
double oDBtop=0; /// Right
</code></pre>
<p>I want to read the values of <code>input_file.csv</code> and assign them to my variables, so that if I type:</p>
<pre><code>cout<<Dist<<" "<<PosAi<<" "<<PosAo<<" "<<
</code></pre>
<p>...........etc. <code>;</code></p>
<p>I get the following list on the console:</p>
<pre><code>10 0 20 0.4 0.1333382222 0 0.5 10 20 0.76 0.3 0.1 0.2
</code></pre>
<p>But I don't know how to use fsteam for that, could you please help a bit?
Thanks!</p>
<hr>
<p>Ok here's the answer if ever some beginner like me gets the same problem:</p>
<pre><code>#include <iostream>
#include <fstream>
using namespace std;
/// geometry
double Dist=0; ///Distance between the 2
double PosAi = 0;
double PosAo = 0;
double PosBi = 0;
double PosBo = 0; ///positions i/o
/// densities
double iDA=0;
double oDA=0;
double iDAtop=0;
double oDAtop=0; /// Left
double iDB=0;
double oDB=0;
double iDBtop=0;
double oDBtop=0; /// Right
int main()
{
ifstream ifs ("input.csv");
if (!ifs)
// process error
ifs >> Dist;
ifs >> PosAi;
ifs >> PosAo;
ifs >> PosBi;
ifs >> PosBo;
ifs >> iDA;
ifs >> oDA;
ifs >> iDAtop;
ifs >> oDAtop;
ifs >> iDB;
ifs >> oDB;
ifs >> iDBtop;
ifs >> oDBtop;
// print variables
cout << Dist << " " << PosAi << " " << PosAo << " " << PosBi << " " << PosBo << " " << iDA << " " << oDA << " " << iDAtop << " " << oDAtop << " " << iDB << " " << oDB << " " << iDBtop << " " << oDBtop << endl;
}

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type with complex and nested objects
|
<p>I`m trying to build web api for complex object. For this aim I built the custom binder which deserialize this object from JSON.</p>
<p>My Customer Binder looks like:</p>
<pre><code>var paramType = p_BindingContext.ModelType;
dynamic updatedParam = Activator.CreateInstance(paramType);
JsonReader reader = new JTokenReader(JObject.Parse
(p_ActionContext.Request.Content.ReadAsStringAsync().Result));
JObject jObject = JObject.Load(reader);
JsonSerializer serializer = new JsonSerializer();
serializer.Populate(jObject.CreateReader(), updatedParam);//Here the exception thorws
p_BindingContext.Model = updatedParam;
</code></pre>

<pre><code> public class ModelRegisterUserRequest{

To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

Also the solutions on this site are excisted but not supports such complex problem.</p>

Spring Batch: Retrying a tasklet using @Retryable and @EnableRetry annotation
|
<p>I have this tasklet which uploads a file to Amazon S3. Now, I want to retry the tasklet execution whenever an <code>AmazonClientException</code> is thrown. I figured using <code>@Retryable</code> annotation will do the job.</p>
<p>Tasklet:</p>
<pre><code>@Component
@StepScope
@Retryable(value=AmazonClientException.class, stateful=true, backoff=@Backoff(2000))
public class S3UploadTasklet extends ArgsSupport implements Tasklet {
@Autowired
private S3Client s3Client;
@Autowired
private S3Properties s3Properties;
private static final Logger LOGGER = LoggerFactory.getLogger(S3UploadTasklet.class);
private static final String FILE_EXTENSION = ".gpg";
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
try {
String localFilename = getTempOutputFilename() + FILE_EXTENSION;
String s3Filename = s3Properties.getReportPath() + getS3OutputFilename() + FILE_EXTENSION;
File f = new File(localFilename);
if(f.exists()) {
LOGGER.info("Uploading " + localFilename + " to s3...");
s3Client.upload(localFilename, s3Filename, s3Properties.getBucketName());
LOGGER.info("Uploading done!");
} else {
throw new RuntimeException("Encrypted file not found! Encryption process might have failed.");
}
} catch(AmazonClientException e) {
LOGGER.error("Problems uploading to S3. " + e.getMessage(), e);
throw e;
} catch(RuntimeException e) {
LOGGER.error("Runtime error occured. " + e.getMessage(), e);
throw e;
}
return RepeatStatus.FINISHED;
}
}
</code></pre>
<p>Job configuration:</p>
<pre><code>@Configuration
@EnableBatchProcessing
@EnableRetry
public class BatchConfiguration {
@Autowired
private JobBuilderFactory jobBuilderFactory;
@Autowired
private Step generateReport;
@Autowired
private Step encrypt;
@Autowired
private Step upload;
@Autowired
private Step cleanUp;
@Bean
@Transactional(value="appTransactionManager", isolation=Isolation.READ_COMMITTED)
public Job generateReconJob() {
return jobBuilderFactory.get("reconJob")
.incrementer(new RunIdIncrementer())
.start(generateReport)
.on("COMPLETED").to(encrypt)
.from(generateReport)

}
}
</code></pre>
<p>However, it doesn't do what it is supposed to do. The batch job still doesn't retry the tasklet when the exception is thrown.</p>
<p>Any thoughts?</p>
<p>Here's the config also</p>
<pre><code>@Configuration
public class ReportConfiguration {
...

<p>How can I solve this?</p>

Android/Java - Test if date was last month
|
<p>I am working on an app where I store some information between each use, this data essentially boils down to counting the number of times an event has happened today, this week, this month and in the apps lifetime. I store this data in 4 distinct counters I can load/save using SharedPreferences.</p>
<p>Alongside the data I store the "last run time" of the app as a date, my plan was that during load time I will load in the counters then test the stored date against today's date to determine which counters need to be cleared.</p>
<p>Sounds simple right!</p>
<p>After pulling my hair out for a while and going backward and forwards through the Calendar documentation I think I understand them enough to come up with the following:</p>
<pre><code> Calendar last = Calendar.getInstance();
last.setTimeInMillis(lastDate);
Calendar today = Calendar.getInstance();
today.add(Calendar.DATE, -1);
if ( !last.after(today) )
{
today = 0;
}
today.add(Calendar.WEEK_OF_MONTH, -1);
today.set(Calendar.DAY_OF_WEEK, Calendar.SUNDAY);
if ( !last.after(today) )
{
today = 0;
week = 0;
}
today = Calendar.getInstance();
today.add(Calendar.MONTH, -1);
today.set(Calendar.DATE, today.getActualMaximum(Calendar.DATE));
if ( !last.after(today) )
{
today = 0;
week = 0;
month = 0;
}
</code></pre>
<p>I think this should be fine, however the issue I have is testing, testing today is easy, however testing the month logic would require either waiting a month, or writing a test case which uses the Calendar API to simulate an old date, however I can't write the test case if my assumptions on how the API works was wrong in the first place!</p>
<p>Therefore, after a large wall of text my question is... does the above block of code look sane, or have I completely mis-understood working with dates in Java?</p>
<p>Thanks!</p>
<h2>Edit:</h2>
<p>Second pass at the code:</p>
<p>Does this look any more sensible? If I am understanding things correctly I am now attempting to compare the end of the date that was last saved with the very start of today, this week and this month.</p>
<pre><code>Calendar last = Calendar.getInstance();
last.setTimeInMillis(lastDate);
last.set(Calendar.HOUR_OF_DAY, last.getActualMaximum(Calendar.HOUR_OF_DAY));
last.set(Calendar.MINUTE, last.getActualMaximum(Calendar.MINUTE));
last.set(Calendar.SECOND, last.getActualMaximum(Calendar.SECOND));
last.set(Calendar.MILLISECOND, last.getActualMaximum(Calendar.MILLISECOND));
Calendar todayStart = Calendar.getInstance();
todayStart.set(Calendar.HOUR_OF_DAY, todayStart.getActualMinimum(Calendar.HOUR_OF_DAY));
todayStart.set(Calendar.MINUTE, todayStart.getActualMinimum(Calendar.MINUTE));
todayStart.set(Calendar.SECOND, todayStart.getActualMinimum(Calendar.SECOND));
todayStart.set(Calendar.MILLISECOND, todayStart.getActualMinimum(Calendar.MILLISECOND));
// If the last recorded date was before the absolute minimum of today
if ( last.before(todayStart) )
{
todayCount = 0;
}
Calendar thisWeekStart = Calendar.getInstance();
thisWeekStart.set(Calendar.HOUR_OF_DAY, thisWeekStart.getActualMinimum(Calendar.HOUR_OF_DAY));
thisWeekStart.set(Calendar.MINUTE, thisWeekStart.getActualMinimum(Calendar.MINUTE));
thisWeekStart.set(Calendar.SECOND, thisWeekStart.getActualMinimum(Calendar.SECOND));
thisWeekStart.set(Calendar.DAY_OF_WEEK, thisWeekStart.getFirstDayOfWeek());
thisWeekStart.set(Calendar.MILLISECOND, thisWeekStart.getActualMinimum(Calendar.MILLISECOND));
// If the last date was before the absolute minimum of this week then clear
// this week (and today, just to be on the safe side)
if ( last.before(thisWeekStart) )
{
todayCount = 0;
weekCount = 0;
}
Calendar thisMonthStart = Calendar.getInstance();
thisMonthStart.set(Calendar.HOUR_OF_DAY, thisMonthStart.getActualMinimum(Calendar.HOUR_OF_DAY));
thisMonthStart.set(Calendar.MINUTE, thisMonthStart.getActualMinimum(Calendar.MINUTE));
thisMonthStart.set(Calendar.SECOND, thisMonthStart.getActualMinimum(Calendar.SECOND));
thisMonthStart.set(Calendar.DAY_OF_MONTH, thisMonthStart.getActualMinimum(Calendar.MONTH));
thisMonthStart.set(Calendar.MILLISECOND, thisMonthStart.getActualMinimum(Calendar.MILLISECOND));

Mongoengine - command find requires authentication
|
<p>I am new to using Mongoengine with an authenticated MongoDB.</p>
<p>I have a Mongo Database called 'gambit_test'. I have enabled authentication on it and I have a proper user that can I authenticate into the database to perform read and write.</p>
<p>I created the user for 'gambit_test' using the following command in Mongo Client:</p>
<pre><code>use gambit_test
db.createUser({
user: "gambit_admin",
pwd: "xxxxxx",
roles:[{role: "userAdmin" , db:"admin"}]
})
</code></pre>
<p>When I log into MongoDB to check my user status, I use a command as follows (logging in as a super admin):</p>
<pre><code>mongo -u sup_admin -p yyyyyyyy
</code></pre>
<p>To verify my user status, here is what I run:</p>
<pre><code>use gambit_test
show users
</code></pre>
<p>It returns the following:</p>
<pre><code>{
"_id" : "gambit_test.gambit_admin",
"user" : "gambit_admin",
"db" : "gambit_test",
"roles" : [
{
"role" : "readWrite",
"db" : "gambit_test"
},
{
"role" : "dbAdmin",
"db" : "gambit_test"
}
],
"mechanisms" : [
"SCRAM-SHA-1",
"SCRAM-SHA-256"
]
}
</code></pre>
<p>Inside my Python <code>test.py</code> code, here is what I am doing:</p>
<pre><code>from mongoengine import *
class History(Document):
name = StringField(required=True)
if __name__ == "__main__":
try:
connect('gambit_test')
History.objects().get()
except Exception as e:
connect(host='mongodb://gambit_admin:xxxxxx@localhost' +
':27017/gambit_test')
History.objects().get()
</code></pre>
<p>When I try to run the above python code, I get the following error:</p>
<pre><code>Traceback (most recent call last):
File "test.py", line 12, in <module>
History.objects().get()
File "/home/ubuntu/gambit/genv/lib/python3.6/site-packages/mongoengine/queryset/base.py", line 267, in get

raise OperationFailure(msg % errmsg, code, response)
pymongo.errors.OperationFailure: command find requires authentication
</code></pre>
<p>I have no clue why this is happening. The reason is I can perform normal find() and insert() using Mongo client. But, when I use Mongoengine, things break...</p>
<p>Any help would be very much appreciated.</p>

How to read healthKit Heartrate data?
|
<p>I know this questions been asked, but hasn't really been answered. I've tried things from threads like this:
<a href="https://stackoverflow.com/questions/31440205/heart-rate-with-apples-healthkit">Heart Rate With Apple's Healthkit</a></p>
<p>I tried converting this from Objective-C to Swift but didn't work.</p>
<p>My question is, what's the best way to read heart rate data from health kit. I want to be able to read every heart rate measurement from the time it started taking them, and I want to be able to see the time/day stamps of said measurements.</p>
<p>I asked for permission here: </p>
<pre><code>import Foundation
import UIKit
import HealthKit
class HealthKitManager: NSObject {
static let healthKitStore = HKHealthStore()
static func authorizeHealthKit() {
let healthKitTypes: Set = [
HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)!,
]
healthKitStore.requestAuthorizationToShareTypes(healthKitTypes,
readTypes: healthKitTypes) { _, _ in }
}
}
</code></pre>
<p>Here is my view Controller code for now (I'm not sure why this doesn't work):</p>
<pre><code>import UIKit
import HealthKit
class ViewController: UIViewController {
let health: HKHealthStore = HKHealthStore()
let heartRateUnit:HKUnit = HKUnit(fromString: "count/min")
let heartRateType:HKQuantityType = HKQuantityType.quantityTypeForIdentifier(HKQuantityTypeIdentifierHeartRate)!
var heartRateQuery:HKQuery?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func authorizeTapped(sender: AnyObject) {
print("button tapped")
self.createStreamingQuery()
HealthKitManager.authorizeHealthKit()
}
func createStreamingQuery() -> HKQuery
{
let queryPredicate = HKQuery.predicateForSamplesWithStartDate(NSDate(), endDate: nil, options: .None)
let query:HKAnchoredObjectQuery = HKAnchoredObjectQuery(type: self.heartRateType, predicate: queryPredicate, anchor: nil, limit: Int(HKObjectQueryNoLimit))
{ (query:HKAnchoredObjectQuery, samples:[HKSample]?, deletedObjects:[HKDeletedObject]?, anchor:HKQueryAnchor?, error:NSError?) -> Void in
if let errorFound:NSError = error
{
print("query error: \(errorFound.localizedDescription)")
}
else
{
//printing heart rate
if let samples = samples as? [HKQuantitySample]
{
if let quantity = samples.last?.quantity
{
print("\(quantity.doubleValueForUnit(self.heartRateUnit))")
}
}
}

What is the best way to read and write data to a buffer for my bar code reader?
|
<p>I need to write a driver for a bar code reader for Linux in C. The bar code reader works through the serial bus. When I send a set of commands to the bar code reader, the bar code reader should return status messages to me. I managed to configure the port and to create a signal handler. In the signal handler, I read the data which the serial bus receives.</p>
<p>So the question is: Should I read the data in buffer and then work with it? And can I even write the data in the buffer with the port configured in this way? When the device replies to me, according to that reply data, I need to send another command to the device.
Also, can I use <code>write()</code> to write the messages? If I can’t use that, what command should I use?
And can you help me a little with the write command?</p>
<p>The command that I send to the device is always 7 bytes, but the reply data varies between 7-32 bytes. If the read function sends different number of bytes that are read, how can I be sure that I received all of the data, so I can work with it?</p>
<p>Here is some code that I've written. Am I going in the right direction?
Once more, the idea is very simple: I am sending a command to a device, and the device interupt me and replies. I read what was send, I work with the reply data, and according to that data, I am send another command.
Thanks in forward. </p>

null pointer exception when retrieving from HashMap even though containsKey() returns true
|
<p>I've been developing an Android guitar app, and currently I'm having some problems with <code>HashMap</code>.</p>
<p>To sum it up, I get a <strong>nullpointer exception</strong> when I try to retrieve a value from a <code>HashMap</code> with <code>get(key)</code> despite <code>containsKey(key)</code> returning <code>true</code> for that key.</p>
<p>Specifically, I have an instance <code>_currentPreset</code> of a class, which has a <code>HashMap</code> called <code>_maxCoordRange</code>, which is initialized in the class like this: </p>
<pre><code>private Map<String, Float> _maxCoordRange = new HashMap<String, Float>();
</code></pre>
<p>This parameter is not modified in the constructors of the class. Instead, it can only be modified by the following method:</p>
<pre><code>public void setMaxCoordRange(String parName, float value) {
_maxCoordRange.put(parName, value);
}
</code></pre>
<p>and accessed by:</p>
<pre><code>public float getMaxCoordRange(String parName) {
return _maxCoordRange.get(parName);
}
</code></pre>
<p>Once I've created the <code>_currentPreset</code> instance, I set some values to the <code>_maxCoordRange</code> map like this:</p>
<pre><code>for (int i = 0; i < _currentPreset.getCoordiates().size(); i++) {
_currentPreset.setMaxCoordRange(_currentPreset.getParNames().get(i), 0.75f);
}
</code></pre>
<p>In other parts of the code I do the following:</p>
<pre><code>if(_currentPreset.getMaxCoordRange().containsKey(pareterName)){
cord.setMaxValueCoord(_currentPreset.getMaxCoordRange(pareterName));
}
</code></pre>
<p>Here is the odd part. I get a nullpointer exeption when I try to retrieve the value corresponding to the <code>pareterName</code> from the <code>HashMap</code> with <code>getMaxCoordRange</code>, despite <code>containsKey(key)</code> returning true.</p>
<p>I did some debugging and I found something rather strange to me.
When I finished putting the values in the map, in the expressions tag (when in debugging mode in eclipse), the table looks like this:</p>
<pre><code>table HashMap$HashMapEntry[16] (id=829660787832)

<p>There should be 10 values, and there are, but 2 of them are in the <code>next</code> field of elements 14 and 15. I read that this is the way the hashMaps arrange the data in order to be more efficient, but couldn't it be the reason why I'm not able to retrieve the values?</p>
<p>Sorry about giving so much information, but I don't really know where the problem is. I've used HashMaps before and I didn't have this problem.</p>
<p>Any ideas on how can i solve this and finally get my values from the map?</p>

Android HTTPPost List<NameValuePair> post to php?

<p>I have been searching for hours and I am still unclear on <code>HTTPPost</code> method. I have code like this...</p>

How do I fix 403 Errors when trying to display an SVG <image>?
|
<p>I'm building an interactive report based on this: <a href="https://avocode.com/design-report-2017" rel="nofollow noreferrer">https://avocode.com/design-report-2017</a></p>
<p>Everything worked great on localhost, but when I uploaded it to the server, I'm getting a 403 (Forbidden) error for all of the SVG images.</p>
<p>I have tried using both relative and absolute paths for the images. Images not in <code><image></code> tags (regular <code><img></code>) work well.</p>
<p>Based on this question: <a href="https://stackoverflow.com/questions/25157431/403-forbidden-error-when-displaying-svg-image">403 forbidden error when displaying svg image</a>, it really sounds like the problem is that the server does not have the proper permissions to load SVG images. </p>
<p>However, I can't seem to find what the permissions need to be <em>changed to</em>. I don't have access to make server changes and have no idea what to tell the back-end developer to change.</p>
<p>I've also read that xlink:href is deprecated (<a href="https://css-tricks.com/on-xlinkhref-being-deprecated-in-svg/" rel="nofollow noreferrer">https://css-tricks.com/on-xlinkhref-being-deprecated-in-svg/</a>) and should be replaced with <code><use></code>, but I can't find documentation on how to use <code><use></code> tags in conjunction with <code><image></code> tags. MDN (<a href="https://developer.mozilla.org/en-US/docs/Web/SVG/Element/image" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/SVG/Element/image</a>) and W3C (<a href="https://www.w3.org/TR/SVG11/struct.html#ImageElement" rel="nofollow noreferrer">https://www.w3.org/TR/SVG11/struct.html#ImageElement</a>) still use xlink:href in their <code><image></code> documentation.</p>
<p>If the error is due to xlink:href deprecation, how do I properly reference an image file within an <code><svg></code>? If <code><use></code> is the preferred method, how would I rewrite the above code to accommodate?</p>
<p>Any help on rewriting my code to properly display the images or reconfiguring the server to display them would be a life-saver.</p>
<p>Thank you for your time.</p>

Program to determine total stops taken by elevator
|
<p>I was asked a question to write a optimal program that would determine the total number of stops a elevator has taken to serve X number of people. Question description is as below.</p>
<p>There is a elevator in a building with M floors, this elevator can take a max of X people at a time or max of total weight Y. Given that a set of people has arrived and their weight and the floor they need to stop given how many stops has the elevator taken to serve all the people. Consider elevator serves in the first come first serve basis.</p>
<p>E.g. Let Array A be the weight of people to be considered
A[] = {60, 80, 40 }</p>
<p>Let Array B be the floors where person needs to be dropped respectively
B[] = {2, 3, 5}</p>
<p>Total building floors be 5,max allowed person in elevator be 2 at a time with max weight capacity being 200
For this example the elevator would take total of 5 stops floors ground, 2, 3,ground, 5 , ground</p>
<p>What would be the optimal code for this?</p>
<p>One of my solution is as below. Is there any other better solutions?</p>
<pre><code>class Solution
{
/// <summary>
/// Return total stops used
/// </summary>
/// <param name="A">weight of people</param>
/// <param name="B">floors they need to get down</param>
/// <param name="M">total floors in the building</param>
/// <param name="X">Max people to carry at a time</param>
/// <param name="Y">max weight to carry at a time</param>
/// <returns></returns>
public int solution(int[] A, int[] B, int M, int X, int Y)
{
// write your code in C# 6.0 with .NET 4.5 (Mono)
int totalStops = 0;
long totalWeightPerRound = 0;
int maxPersonsCount = 0;
List<int> lstFloors = new List<int>();
int currPerson = 0;
bool startLift = false;
while (currPerson < A.Length)
{
if ((totalWeightPerRound + A[currPerson]) <= Y && (maxPersonsCount+1) <= X)
{
totalWeightPerRound += A[currPerson];
maxPersonsCount++;
lstFloors.Add(B[currPerson]);
if (currPerson == A.Length - 1)
startLift = true;
currPerson++;
}
else
{
startLift = true;
}
if (startLift)
{
totalStops += lstFloors.Distinct().Count() + 1;
lstFloors.Clear();
maxPersonsCount = 0;
totalWeightPerRound = 0;
startLift = false;
}
}
return totalStops;

SQLite subtract time difference between two tables if there is a match
|
<p>I need some help with a SQLite Query. I have two tables, a table called 'production' and a table called 'pause':</p>
<pre><code>CREATE TABLE production (
date TEXT,
item TEXT,
begin TEXT,
end TEXT
);
CREATE TABLE pause (
date TEXT,
begin TEXT,
end TEXT
);
</code></pre>
<p>For every item which is produced, an entry in the table production with the current date, the start time and the end time (two timestamps in the format HH:MM:SS) is created. So let's assume, the production table looks like: </p>
<pre><code>+------------+-------------+------------+----------+
| date | item | begin | end |
+------------+-------------+------------+----------+
| 2013-07-31 | Item 1 | 06:18:00 | 08:03:05 |
| 2013-08-01 | Item 2 | 06:00:03 | 10:10:10 |
| 2013-08-01 | Item 1 | 10:30:15 | 14:20:13 |
| 2013-08-01 | Item 1 | 15:00:10 | 16:00:00 |
| 2013-08-02 | Item 3 | 08:50:00 | 15:00:00 |
+------------+-------------+------------+----------+
</code></pre>
<p>The second table also contains a date and a start and an end time. So let's assume, the 'pause' table looks like:</p>
<pre><code>+------------+------------+----------+
| date | begin | end |
+------------+------------+----------+
| 2013-08-01 | 08:00:00 | 08:30:00 |
| 2013-08-01 | 12:00:00 | 13:30:00 |
| 2013-08-02 | 10:00:00 | 10:30:00 |
| 2013-08-02 | 13:00:00 | 14:00:00 |
+------------+------------+----------+
</code></pre>
<p>Now I wanna get a table, which contains the time difference between the production begin and end time for every item. If there is a matching entry in the 'pause' table, the pause time should be subtracted. </p>
<p>So basically, the end result should look like:</p>
<pre><code>+------------+------------+-------------------------------------------------+
| date | Item | time difference (in seconds), excluding pause |
+------------+------------+-------------------------------------------------+
| 2013-07-31 | Item 1 | 6305 |
| 2013-08-01 | Item 1 | 12005 |
| 2013-08-01 | Item 2 | 13207 |
| 2013-08-02 | Item 3 | 16800 |
+------------+------------+-------------------------------------------------+
</code></pre>
<p>I am not really sure, how I can accomplish it with SQLite. I know that it is possible to do this sort of calculation with Python, but in the end I think it would be better to let the database do the calculations. Maybe someone of you could give me a hint on how to solve this problem. I tried different queries, but I always ended up with different results than I expected. </p>

Heading identification with Regex
|
<p>I'm wondering how I can identify headings with differing numerical marking styles with one or more regular expressions assuming sometimes styles overlap between documents. The goal is to extract all the subheadings and data for a specific heading in each file, but these files aren't standardized. Is regular expressions even the right approach here?</p>
<p>I'm working on a program that parses a .pdf file and looks for a specific section. Once it finds the section it finds all subsections of that section and their content and stores it in a <code>dictionary<string, string></code>. I start by reading the entire pdf into a string, and then use this function to locate the "marking" section.</p>
<pre><code>private string GetMarkingSection(string text)
{
int startIndex = 0;
int endIndex = 0;
bool startIndexFound = false;
Regex rx = new Regex(HEADINGREGEX);
foreach (Match match in rx.Matches(text))
{
if (startIndexFound)
{
endIndex = match.Index;
break;
}
if (match.ToString().ToLower().Contains("marking"))
{
startIndex = match.Index;
startIndexFound = true;
}
}
return text.Substring(startIndex, (endIndex - startIndex));
}
</code></pre>
<p>Once the marking section is found, I use this to find subsections.</p>
<pre><code>private Dictionary<string, string> GetSubsections(string text)
{
Dictionary<string, string> subsections = new Dictionary<string, string>();
string[] unprocessedSubSecs = Regex.Split(text, SUBSECTIONREGEX);
string title = "";
string content = "";
foreach(string s in unprocessedSubSecs)
{
if(s != "") //sometimes it pulls in empty strings
{
Match m = Regex.Match(s, SUBSECTIONREGEX);
if (m.Success)
{
title = s;
}
else
{
content = s;
if (!String.IsNullOrWhiteSpace(content) && !String.IsNullOrWhiteSpace(title))
{
subsections.Add(title, content);
}
}
}
}
return subsections;
}
</code></pre>
<p>Getting these methods to work the way I want them to isn't an issue, the problem is getting them to work with each of the documents. <strong>I'm working on a commercial application so any API that requires a license isn't going to work for me.</strong>
These documents are anywhere from 1-16 years old, so the formatting varies quite a bit. <a href="https://regex101.com/r/6RckWL/5" rel="nofollow noreferrer">Here is a link to some sample headings and subheadings from various documents.</a> But to make it easy, here are the regex patterns I'm using:</p>
<ul>
<li>Heading: <code>(?m)^(\d+\.\d+\s[ \w,\-]+)\r?$</code></li>
<li>Subheading: <code>(?m)^(\d\.[\d.]+ ?[ \w]+) ?\r?$</code></li>
<li>Master Key: <code>(?m)^(\d\.?[\d.]*? ?[ \-,:\w]+) ?\r?$</code></li>
</ul>
<p>Since some headings use the subheading format in other documents I am unable to use the same heading regex for each file, and the same goes for my subheading regex.</p>
<p>My alternative to this was that I was going to write a master key (listed in the regex link) to identify all types of headings and then locate the last instance of a numeric character in each heading (5.1.X) and then look for 5.1.X+1 to find the end of that section.</p>
<p>That's when I ran into another problem. Some of these files have absolutely no proper structure. Most of them go from 5.2->7.1.5 (5.2->5.3/6.0 would be expected)</p>
<p>I'm trying to wrap my head around a solution for something like this, but I've got nothing... I am open to ideas not involving regex as well.</p>
<p>Here is my updated <code>GetMarkingSection</code> method:</p>
<pre><code>private Dictionary<string, string> GetMarkingSection(string text)
{
var headingRegex = HEADING1REGEX;
var subheadingRegex = HEADING2REGEX;
Dictionary<string, string> markingSection = new Dictionary<string, string>();
if (Regex.Matches(text, HEADING1REGEX, RegexOptions.Multiline | RegexOptions.Singleline).Count > 0)
{
foreach (Match m in Regex.Matches(text, headingRegex, RegexOptions.Multiline | RegexOptions.Singleline))
{
if (Regex.IsMatch(m.ToString(), HEADINGMASTERKEY))
{
if (m.Groups[2].Value.ToLower().Contains("marking"))
{
var subheadings = Regex.Matches(m.ToString(), subheadingRegex, RegexOptions.Multiline | RegexOptions.Singleline);
foreach (Match s in subheadings)
{
markingSection.Add(s.Groups[1].Value + " " + s.Groups[2].Value, s.Groups[3].Value);
}
return markingSection;
}
}
}
}
else
{
headingRegex = HEADING2REGEX;
subheadingRegex = HEADING3REGEX;
foreach(Match m in Regex.Matches(text, headingRegex, RegexOptions.Multiline | RegexOptions.Singleline))
{
if(Regex.IsMatch(m.ToString(), HEADINGMASTERKEY))
{
if (m.Groups[2].Value.ToLower().Contains("marking"))
{
var subheadings = Regex.Matches(m.ToString(), subheadingRegex, RegexOptions.Multiline | RegexOptions.Singleline);
foreach (Match s in subheadings)
{
markingSection.Add(s.Groups[1].Value + " " + s.Groups[2].Value, s.Groups[3].Value);
}
return markingSection;
}
}
}
}
return null;
}

How to retrieve browser session data in ASP.Net MVC Controller?
|
<p>I'm having a pretty tough time with this issue. I've done a lot of research but haven't found anything that works!</p>
<p><strong>What I want to do:</strong>
I want to use javascript to capture the user's timezone and utc timezone offset, store these two pieces of data in the browsers session, and then retrieve them in the controller.</p>
<p><strong>What is working:</strong>
My javascript is working to extract the user's timezone and timezone offset and save these two variables into the session. The following is my working JS:</p>
<pre><code><script type="text/javascript">
window.onload = function () {
var UserTime = new Date();
var stringtz = UserTime.toString();
var tzstart = stringtz.indexOf("(") + 1;
var tzend = stringtz.indexOf(")");
var userTZ = stringtz.slice(tzstart, tzend);
sessionStorage.setItem("userTZOffset", UserTime.getTimezoneOffset().toString());
sessionStorage.setItem("userTZ", userTZ);
};
</script>
</code></pre>
<p><strong>What is not working:</strong>
When the user signs in, I want to grab the two variables (userTZ and userTZOffset) saved in the session and create claims for them. However, when I try to pull these into my controller I get null as the values. Upon further inspection, I can see the session timeout, id, etc but the keys and values are blank.</p>
<p>Here is a snipped of code from my sign in action in my controller:</p>
<pre><code> var claims = UserManager.GetClaims(user.Id);
var timezoneclaim = claims.First(c => c.Type == "UserTZ");
UserManager.RemoveClaim(user.Id, timezoneclaim);
var timezoneoffsetclaim = claims.First(c => c.Type == "UserTZOffset");
UserManager.RemoveClaim(user.Id, timezoneoffsetclaim);
var test = HttpContext.Session["userTZ"];
var test2 = HttpContext.Session["userTZOffset"];
UserManager.AddClaim(user.Id, new Claim("UserTZ", test.ToString()));
UserManager.AddClaim(user.Id, new Claim("UserTZOffset", test2.ToString()));
</code></pre>
<p>I set breakpoints on this and walk through the code but everytime, test and test2 are null. When I look into the session itself on the breakpoints I see SessionId, Timeout, etc but the count is 0 and the Key count is 0.</p>
<p>I've tried:</p>
<ol>
<li>Adding remove name="Session" and add name="Session" type="System.Web.SessionState.SessionStateModule" to my webconfig based on a similar issue I found <a href="https://stackoverflow.com/questions/218057/httpcontext-current-session-is-null-when-routing-requests">here</a>.</li>
<li>I tried adding the Microsoft.Aspnet.Session nuget package and following <a href="http://benjii.me/2015/07/using-sessions-and-httpcontext-in-aspnet5-and-mvc6/" rel="nofollow noreferrer">this</a> tutorial but my project's startup.cs doesn't have a ConfigureServices section and adding my own didn't work either.</li>
<li>I set the session state to InProc in the webconfig based on what I found <a href="https://stackoverflow.com/questions/28081004/mvc-5-session-is-null">here</a> but again, nothing changed.</li>
</ol>
<p>Thoughts?</p>

<pre><code> [AcceptVerbs(HttpVerbs.Post)]
public ActionResult EditUser(int? id, FormCollection form)
{
var user = new User();
using (var db = new UMSEntities { DeferredLoadingEnabled = false })
{
if (id != null)
{
user = db.Users.FirstOrDefault(p => p.UserID.Equals((int) id));
db.LoadProperty(user, p => p.UserProfiles);
db.LoadProperty(user, p => p.UserCompanyProfile);
}
else
{
user.UserGuid = Guid.NewGuid();
user.DateCreated = DateTime.Now;
user.DateLastActivity = DateTime.Now;
user.DateModified = DateTime.Now;
user.Password = "demo";
user.Version = 0;
user.SecretAnswer = "";
user.SecretQuestion = "";
user.IsApproved = true;
user.IsActive = true;
user.UserProfiles = new UserProfile();
user.UserCompanyProfile = new UserCompanyProfile
{
EmployeeID = "",
HireDate = DateTime.Now,
Title = "",
UserCode = "",
Company = db.Companies.First(p => p.CompanyID == 8)
};
db.Users.InsertOnSaveChanges(user);
}
TryUpdateModel(user);
db.SaveChanges();
}
</code></pre>
<p>Editing an exist user works perfect (notice if id != null). However, it is the portion of code that adds a new user. It works until I get to the portion of code where I add the UserCompanyProfile to the user object. If I comment this code out, it works just fine. The problem arises when I try to attach a company to the UserCompanyProfile by querying the database-- I get this error.</p>
<pre><code>Entities in 'UMSEntities.UserCompanyProfiles' participate in the 'FK__UserCompa__Compa__25869641' relationship. 0 related 'Companies' were found. 1 'Companies' is expected.
</code></pre>
<p>By the way, it does in fact return one Company object (it is of type PocoProxies.CompanyProxy). Any help would certainly be appreciated!</p>

CSS layout zoom issue
|
<p>My issue is that when I zoom in or out of the page (in all the browsers I tried), only some parts of it are displayed as zoomed (the contents that are in the divs, but not the divs themselves). I put the borders to show it easily.</p>
<p>When I searched for a solution, all of them mentioned that it is because of fixed width values by using pixels (px). So, I used <code>%</code> when putting values to width and height; but still, the issue remains...</p>
<p><strong>Here are some screenshots to illustrate my problem:</strong></p>

Android default button styling not working
|
<p>I'm trying to set up my styles to make all buttons a particular color combination, specifically blue with white text. Here's my main styles.xml:</p>
<pre><code><resources>
<style name="CustomTheme" parent="MaterialDrawerTheme.Light.DarkToolbar">
<!-- various items -->
<item name="android:buttonStyle">@style/ButtonStyle</item>
</style>
<!-- a couple of other styles -->
<style name="ButtonStyle" parent="android:style/Widget.Button">
<item name="android:textSize">19sp</item>
<item name="android:textColor">@color/primaryTextContrast</item>
<item name="android:background">@color/primary</item>
</style>
</resources>
</code></pre>
<p>And in the manifest:</p>
<pre><code> <application
android:name=".CustomApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/application_name"
android:theme="@style/CustomTheme">
</code></pre>
<p><code>color/primary</code> is dark blue, and <code>color/primaryTextContrast</code> is white. On Lollipop, the button looks perfect. On a 4.1 device, it's light gray with black text. Every resource I've found for doing this looks exactly like what I'm doing so I don't know what I'm missing here.</p>
<p>I'm having a similar issue with controlling text size in the base style definition as well.</p>
<p>Update: here are the colors.</p>
<pre><code><resources>
<color name="primary">#3F51B5</color>
<color name="dark">#303F9F</color>
<color name="accent">#FFCA28</color>
<color name="background">@android:color/white</color>
<!-- Color for text displayed on top of the primary or dark color -->
<color name="primaryTextContrast">@android:color/white</color>
<!-- Color for text displayed on the background color (which I think will always be white) -->
<color name="basicText">@color/primary</color>
<!-- Color for text displayed on the accent color -->
<color name="accentText">#303F9F</color>
</resources>
</code></pre>
<p>Here's v19/styles.xml:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="FullscreenTheme" parent="MaterialDrawerTheme.Light.DarkToolbar.TranslucentStatus">
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
</resources>
</code></pre>
<p>Here's v21:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="CustomTheme">
<item name="android:windowContentTransitions">true</item>
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>
<item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
<item name="android:windowSharedElementExitTransition">@android:transition/move</item>
</style>
</resources>
</code></pre>
<p>I don't think either of these is what's making it work properly on 5.1.</p>

Bootstrap 3.0: Full-Width Color Background, Compact Columns in Center
|
<p>I was looking to make a striped business theme, similar to the one created by W3Schools. The theme can be found <a href="http://www.w3schools.com/bootstrap/bootstrap_theme_company.asp" rel="nofollow">here</a>. It is characterized by horizontal sections, separated by different background colors.</p>
<p>The one issue I had with it was that the columns in Services, Portfolio and Pricing, spanned pretty much the full width of the page, which I did not think looked great, particularly for the three pricing boxes, which i feel should be much narrower and still centered. Let's take those pricing boxes as the example for the purpose of the questions.</p>
<p>So, I embarked upon the task of squeezing these three pricing boxes into a narrower shape, centered on the page, while still maintaining the full-width alternating background color. I came up with three ways to do it:</p>
<h2>1) Place a Container inside a Container-Fluid:</h2>
<pre><code><div id="pricing" class="container-fluid">
<div class="container">
<div class="row">
<div class="col-sm-4 col-xs-12">
BlaBlaBla
</div>
...
</div>
</div>
</div>
</code></pre>
<hr>
<h2>2) Make the following additions/changes to the css and html:</h2>
<pre><code>.fixed-width {
display: inline-block;
float: none;
width: 300px;
}
.row-centered {
text-align: center;
}
</code></pre>
<p>-</p>
<pre><code><div id="pricing" class="container-fluid">
<div class="row row-centered">
<div class="col-sm-4 col-xs-12 fixed-width">
BlaBlaBla
</div>
...
</div>
</div>
</code></pre>
<hr>
<h2>3) 3x col-sm-2, with empty columns on each side</h2>
<p>Keep the container-fluid layout, but instead of having three <code>col-sm-4</code>, I have an empty <code>col-sm-3</code>, three <code>col-sm-2</code>, and finally an empty <code>col-sm-3</code> (for a total of 12 columns).</p>
<hr>
<h2>4) 3x col-sm-2, with offset-3 to center</h2>
<p>Instead of having three col-sm-4, I have one <code>col-sm-2 col-sm-offset-3</code>, then two <code>col-sm-2</code> (this does not add to 12, but i center with offset).**</p>
<hr>
<p>The problem with both (3) and (4) is that once i shrink the browser window, the boxes become too small before they wrap to the next line (i.e. the text flows out of the box). In (4) it seems if i use <code>container</code> (as opposed to <code>container-fluid</code>), the boxes become too narrow in full-screen even.</p>
<p>What is the correct way of doing this? I assume this is an issue almost everyone making business websites stumbles across, yet I was not able to find the answer online having worked on it for hours.</p>
<p>Thanks in advance,</p>
<p>Magnus</p>

AVCodecContext settings for H264 (1080i)

<p>I'm trying to configure x264 for 1080i capturing. Most of these settings below are found in different examples. However, compiled together they don't work. ffmpeg API reports no error, but <code>avcodec_encode_video()</code> always returns zero.</p>
<p>Some of the numbers are strange to me... for example, <code>gop_size</code>. Isn't 250 too high?</p>

AngularJs datatable dynamic table change
|
<p>I am working on a project and i want to do some things which are new to me. I am new in AngularJS and newer in angular data tables.</p>
<p>I got angular data table from <a href="http://l-lin.github.io/angular-datatables/#/welcome" rel="nofollow"><strong>here</strong></a> and is a little bit tricky for me because i don't really know how to use it. Examples are not very explanatory for me.</p>
<p>What i want to do:</p>
<ul>
<li><p>i have a sigle page with some checkboxes on the left</p></li>
<li><p>on the right i want a data table with data provided by server after user clicks on a checkbox</p></li>
<li><p>data table must change dinamicaly because depends on the request i have other headers for data table. For example when user click on "role" objects returned have only 2 fields id and role, i want to render role column but not id. When user clicks on "users" data returned by server has multiple objects which have much more fields, for example : "accNonExp", "accNonLocked", "email", "username" and others.</p></li>
</ul>
<p>How can i do this ?</p>
<p>here is my conde right now :</p>
<p>js :</p>

console.log(response);
});
function getTableData(table) {
$http.post('/master/tableData/' + table).success(function (response) {
console.log(response);
return response;

}
$scope.dataTable = function(DTOptionsBuilder, DTColumnBuilder) {
var vm = this;
vm.dtOptions = DTOptionsBuilder.fromJson($scope.tableData)

CollectionView Cell size to fit Label
|
<p>I have set up a collection view using which scrolls horizontally and displays the elements in the ‘companies’ array. </p>
<p><a href="https://i.stack.imgur.com/NSAD8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NSAD8.png" alt="enter image description here"></a></p>
<p>The cells automatically resize relative to the label width. </p>
<p>I have used the code & storyboard constraints below to achieve this:</p>
<pre class="lang-html prettyprint-override"><code>class addTextStatus: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {
var companies: [String] = ["Everyone","Limited", "Friends", "Only Me", "Test Length Cells", ]
@IBOutlet weak var collectionView: UICollectionView!
@IBOutlet weak var userImage: UIImageView!
override func viewDidLoad(){
collectionView.register(UINib.init(nibName: "statusCompanyCollectionView", bundle: nil), forCellWithReuseIdentifier: "cell4")
if let flowLayout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout {
flowLayout.estimatedItemSize = CGSize(width: 1,height: 1)
}
userImage.layer.masksToBounds = false
userImage.layer.cornerRadius = userImage.frame.height/2
userImage.clipsToBounds = true
}
@IBOutlet weak var backButton: UIButton!
@IBAction func backButton(_ sender: Any) {
dismiss(animated: true, completion: nil)
}
override var preferredStatusBarStyle : UIStatusBarStyle {
return UIStatusBarStyle.default
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.companies.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell4 = collectionView.dequeueReusableCell(withReuseIdentifier: "cell4", for: indexPath) as! statusCompanyCollectionView
cell4.company.text = self.companies[indexPath.item]
return cell4
}
}

<p><a href="https://i.stack.imgur.com/tD2Xf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tD2Xf.png" alt="enter image description here"></a></p>

<p><a href="https://i.stack.imgur.com/mAz1H.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mAz1H.png" alt="enter image description here"></a></p>
<p>The constraints I have used to apply the image behind are below:</p>
<p><a href="https://i.stack.imgur.com/YgTdq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YgTdq.png" alt="enter image description here"></a></p>
<p>Interestingly when I use a UIView instead of a UIImage view it works as expected, I do however need to use image views in this instance.</p>
<p>Why is this occurring and how do I resolve this issue? </p>

setBackgroundColor() doesn't seem to work
|
<p>I have a <code>RelativeLayout</code> and a <code>Button</code> in my <code>Activity</code>
I want to run a code when I click on the <code>Button</code>, so I wrote the following code:</p>
<pre><code><ImageButton
android:id="@+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="@drawable/flashlight"
android:onClick="NightSwitch" />
</code></pre>
<p>and then I have the following in my <code>Activity.java</code></p>
<pre><code>public void NightSwitch(View v){
String One = "1"; //states day
String Zero = "0"; //states night
int color1 = getResources().getColor(R.color.darkblue);
int color2 = getResources().getColor(R.color.white);
RelativeLayout rele = (RelativeLayout) findViewById(R.id.RelativeLayout1);
String state = getString(R.string.night_switch);
if(state.equals(One)){
rele.setBackgroundColor(color1);
}
if(state.equals(Zero)){
rele.setBackgroundColor(color2);
}
}
</code></pre>
<h2>Everything is ok, but <code>setBackgroundColor()</code> does not work and causes a crash. also, how can I debug program in a VB style? Is it even possible?</h2>

Qt Plugins: :-1: error: cannot find -lpnp_basictools

<p>I have been trying for days now to use third party libraries in my simple Qt projects, but to no success so far.</p>

Posting JSON from ajax to Struts2 Action

<p>Hey I am trying to post JSON from Ajax to Struts2 action class method. Little more info: I am running client on WAMP server and Struts2 on Eclipse Tomcat.</p>
<p>My client side code:</p>
<pre><code><html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
var dataObj = {

"name": "Chris"
}, {
"id": "2",
"name": "Kate"
}, {
"id": "3",
"name": "Blade"
}, {
"id": "4",
"name": "Zack"
}]
};
var data1 = JSON.stringify(dataObj);
$(document).ready(function(){
$("button").click(function(){
$.ajax({url:"http://localhost:8080/Core/add",type: "post", data: data1, dataType: 'json', contentType:"application/json;charset=utf-8",async: true,success:function(result){
$("#div1").html(result);
}});
});
});
</script>
</head>
<body>
<div id="div1"><h2>Let jQuery AJAX Change This Text</h2></div>
<button>Get External Content</button>
</body>
</html>
</code></pre>
<p>And this is my Java application stuff:</p>
<p><strong><code>struts.xml</code>:</strong></p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>

<p>All the time when I run my client side code, I can see the following input only from Eclipse console:</p>
<pre><code>[]
Getter Call
</code></pre>
<p>Why is it empty? I expect to have that JSON array from client side but no success. </p>

Symfony2 choice field not working
|
<p>I asked a question here <a href="https://stackoverflow.com/questions/16441771/how-to-use-repository-custom-functions-in-a-formtype">How to use Repository custom functions in a FormType</a> but nobody anwsered, so i did a little digging and advanced a little but i still get this error:</p>
<pre><code>Notice: Object of class Proxies\__CG__\Kpr\CentarZdravljaBundle\Entity\Category
could not be converted to int in /home/kprhr/public_html/CZ_Symfony/vendor/symfony/symfony/src/Symfony/Component/Form/Extension/Core/ChoiceList/ChoiceList.php line 457
</code></pre>
<p>Now this is how my CategoryType looks like:</p>
<pre><code><?php
namespace Kpr\CentarZdravljaBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class CategoryType extends AbstractType
{
private $doctrine;
public function __construct(RegistryInterface $doctrine)
{
$this->doctrine = $doctrine;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Kpr\CentarZdravljaBundle\Entity\Category',
'catID' => null,
));
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$someId = $builder->getData()->getId();
$param = ($someId) ? $someId : 0;
$catID = $options['catID'];
$builder->add('name', 'text', array('attr' => array('class' => 'span6')));

private function getAllChildren($catID)
{
$choices = array();
$children = $this->doctrine->getRepository('KprCentarZdravljaBundle:Category')->findByParenting($catID);
foreach ($children as $child) {
$choices[$child->getId()] = $child->getName();
}
return $choices;
}
public function getName()
{
return 'category';
}
}
</code></pre>
<p>I am accessing the CategoryRepository function findByParenting($parent) from the CategoryType and I am getting the array populated with accurate data back from the function getAllChildren($catID) but the error is there, i think that Symfony framework is expecting an entity field instead of choice field, but dont know how to fix it.
I also changet the formCreate call in the controller giving $this->getDoctrine() as an argument to CategoryType():</p>
<pre><code>$form = $this->createForm(new CategoryType($this->getDoctrine()), $cat, array('catID' => $id));

d3 bar chart using rangeRoundBands - why is there outer padding?
|
<p>I'm creating a bar chart using an ordinal scale for the x axis, and using rangeRoundBands. I'm following this example: <a href="https://bl.ocks.org/mbostock/3885304" rel="nofollow noreferrer">https://bl.ocks.org/mbostock/3885304</a></p>
<p>However, my chart has outer padding -- big spaces at the beginning and end of the axis, where I'd like the bars to fully extend. The screen shot below shows the spaces I'm referring to circled in red.</p>
<p><a href="https://i.stack.imgur.com/Jl58Y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Jl58Y.png" alt="screenshot of bar chart"></a></p>
<p>How can I remove these spaces? I need my margins and the svg width and height to remain the same.</p>
<p>Here is a Plunker with the chart as it is now:

Open html link in a div using jquery
|
<p>I am trying to drag and drop html link into a div element. My requirement here is to open the link in within that div element. I have 2 divisions on my page "left-panel" and "canvas".</p>
<p>Idea here is on my left panel I'll have multiple links, when I drop any of these link in canvas div it should open that html link within the canvas. One thought is to use iframe but I would like to know if this is possible with divs instead of iframe. I tried $.ajax() and load() but none of those seem to work. I'll appreciate your help in this regard. </p>

Leaflet.js and JSON data : optimization and performance
|
<p>I'm currently working on my first real outing using Javascript to build an interactive map of our customer data .</p>
<p>So Far I've got the basics working but the performance starts to drop when I start going above around 500 poi's with markers or 10,000 with circle markers.... if anyone could offer some advise on how to optimize what I've already got or maybe am i best to move to a proper DB like mongo for the json data or do the work server side with Node Js maybe?</p>
<p>Any advice would be much appreciated :)</p>

<p>There are <strong>two</strong> public constructors. Let we deploy this app on server and sent initial request, type the name in <code>inputText</code> and click <code>submit</code>. There is postback request after <code>submit</code> click. Hence, as written in tutroial, we have the following subphase of execute phase:</p>
<ol>
<li>The application view is built or restored.</li>
<li>The request parameter values are applied.</li>
<li>Conversions and validations are performed for component values.</li>
<li>Managed beans are updated with component values.</li>
<li>Application logic is invoked.</li>
</ol>
<p>At what phase instance of managed bean will be created? </p>
<p>What constructor will be invoked for this instance creation and why? I dont understand how it can be observe from the <code>index.xhtml</code> code.</p>

<p>Thanks a lot for helping.</p>
<p><strong>Update :</strong> To clearify, what would like to achieve is </p>
<p>when it is full width e.g. col-lg </p>
<p>it should like this:</p>
<p><img src="https://i.stack.imgur.com/cHIsO.png" alt=""></p>
<p>And when it is mobile width e.g. col-xs</p>
<p>then it should like this:

Having trouble with ellipsis with angularjs

How to convert Action to Func<Task> without running the Task?
|
<p>I have code that works precisely as desired. However, our corporate build server rejects any check-in that has a compiler warning.</p>
<p>The following warning is (as expected) displayed for the Action constructor with the Action to Func conversions, since I am not using an await statement.</p>
<blockquote>
<p>This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.</p>
</blockquote>
<pre><code>public class TransactionOperation
{
private readonly Func<Task> _operation;
private readonly Func<Task> _rollback;
public OperationStatus Status { get; private set; }
public TransactionOperation(Func<Task> operation, Func<Task> rollback)
{
_operation = operation;
_rollback = rollback;
Status = OperationStatus.NotStarted;
}
public TransactionOperation(Action operation, Action rollback)
{
_operation = async () => operation.Invoke();
_rollback = async () => rollback.Invoke();
Status = OperationStatus.NotStarted;
}
public async Task Invoke()
{
try
{
Status = OperationStatus.InProcess;
await _operation.Invoke();
Status = OperationStatus.Completed;
}
catch (Exception ex)
{
//...
}
}
}
</code></pre>
<p>What is a correct way to rewrite that code so that the Action is correctly converted to Func without being executed yet or creating a new thread (i.e. await Task.Run())?</p>
<hr />
<p><strong>Update - Proposed Answer #1</strong></p>
<blockquote>
<p>_operation = () => new Task(operation.Invoke);</p>
<p>_rollback = () => new Task(rollback.Invoke);</p>
</blockquote>
<p>I tried this before. It causes this unit test to never return.</p>
<pre><code>[TestMethod, TestCategory("Unit Test")]
public async Task Transaction_MultiStepTransactionExceptionOnFourthAction_CorrectActionsRolledBack()
{
var operation = new TransactionOperation(PerformAction, () => RollbackOperation(1));
var operation2 = new TransactionOperation(PerformAction, () => RollbackOperation(2));
var operation3 = new TransactionOperation(PerformAction, () => RollbackOperation(3));
var operation4 = new TransactionOperation(ExceptionAction, () => RollbackOperation(4));
var operation5 = new TransactionOperation(PerformAction, () => RollbackOperation(5));
var transaction = new Transaction(new[] { operation, operation2, operation3, operation4, operation5 });
await IgnoreExceptions(transaction.ExecuteAsync);
AssertActionsPerformedThrough(4);
AssertActionsRolledBackThrough(4);
}
</code></pre>
<hr />
<p><strong>Update - Accepted Answer</strong></p>
<pre><code>private async Task ConvertToTask(Action action)
{
action.Invoke();
await Task.FromResult(true);
}
</code></pre>
<p>Here's the updated Action constructor:</p>
<pre><code>public TransactionOperation(Action operation, Action rollback)
{
_operation = () => ConvertToTask(operation);
_rollback = () => ConvertToTask(rollback);
Status = OperationStatus.NotStarted;
}
</code></pre>

C++ Protected Variables Not Inherited
|
<p>I have written some code to calculate the RSA cryptographic algorithm. The program uses classes and inheritance because I want to calculate a public and private key for multiple users. There is a parent class <code>rsa</code> and child classes <code>public_key</code> and <code>private_key</code>.</p>
<p>When compiling the code below, I get many errors. All of them are about the derived classes not having the available fields in their respective constructors (see error message below code). However, these variables are defined with the <code>protected</code> access modifier in the parent class, so they should be accessible to the child class.</p>
<p>One side note: I had the function <code>key</code> in both of the child classes, but I thought it would be better to put it once in the parent class, is this right?</p>
<p>Here is the code:</p>
<pre><code>#include <iostream>
#include <math.h>
using namespace std;
class rsa
{
protected:
int p, q, d, m, n, f, e, c, end, k;
public:
rsa() : n(0), e(0), c(0), k(0), end(0), f(0)
{ }
void set(int , int , int, int);
int key()
{
n = p * q;
f = (p - 1) * (q - 1);
for (k; end < 1; k++)
{
if ((1 + k * f) % d == 0)
{
end = 2;
e = (1 + k * f) / d;
}
}
c = int(pow(m, e)) % n;
return c;
}
};
void rsa::set(int p_, int q_, int d_, int m_)
{
p = p_;
q = q_;
d = d_;
m = m_;
}
class public_key : public rsa
{
public:
public_key() : n(0), e(0), c(0), k(0), end(0), f(0)
{ }
};
class private_key : public rsa
{
public:
private_key() : n(0), e(0), c(0), k(0), end(0), f(0)
{ }
};
int main()
{
public_key usr1, usr2;
private_key usr1r, usr2r;
usr1.set(11, 5, 23, 9);
usr2.set(13, 7, 97, 6);
usr1r.set(17, 7, 51, 8);
usr2r.set(11, 17, 51, 4);
cout << "Public key of user 1: " << usr1.key() << endl;
cout << "Public key o user 2: " << usr2.key() << endl;
cin.get();
return 0;
}
</code></pre>
<p>One of the errors:</p>
<pre><code>error: class ‘private_key’ does not have any field named ‘e’
private_key () : n(0), e(0), c(0), k(0), end(0), f(0) {} ;
</code></pre>
<p>All the other errors are the same but the field name changes.</p>

How to use backBehavior: 'history' on my bottomtabnaviagor

<p>Is there any maximum character limit for base64 encoding? For one of the passwords "xwYgqg8+xnynU7MpceOoJw==" is the encrypted string which gives exception "padding is invalid and can not be removed" while decoding using above code.
In the DecryptStringPassword() function, last line,
return (new StreamReader(csD)).ReadToEnd(); gives the exception.</p>
<p>Same password I encrypted using AES encryption, it gives me
"xwYgqg8+xnynU7MpceOoJ70HuRIIw+OkcDPBVa18mLw=" such a big encrypted password compared to base64 encoding which does not give any exception while decoding.</p>
<p>Is there any limit that base64 encoding gives always 24 characters long encrypted string or any length restriction on the string to be encrypted.</p>
<p>Our one of the users facing this issue while decoding the password. Rest all users have no problem while decoding.</p>

Trouble with client side validation using Struts 2. Xml based validation rules not recognized

ESP-12 wifi module's the GPIO pin is HIGH on turning it on but should be LOW
|
<p>I need help. I am using ESP-12 WiFi module to automate lights of my room and controlling it. But when I turn on my ESP-12 WiFi module the GPIO2 pin, which I set for relay input, is going HIGH (by default it should be LOW) and then freezing. But if I connect GPIO pin after turning ESP on then its working fine. How can I avoid this problem. It is connection problem or related to code??</p>
<p>This is my circuit diagram<img src="https://i.stack.imgur.com/2oG3f.jpg" alt="This is my circuit diagram"></p>

Open USB host communication on a device already connected at the launch of the application
|
<p>I'm developping an application and I need to manage a device using the usb host mode of my tablette.</p>
<p>At this point, I could only activate the USB, at the connection of the device.
Process step :</p>
<ol>
<li>No application launch, connection of the device.<br></li>
<li>Android ask me if I wan't to launch my application<br></li>
<li>I accept<br>
Then the application start, and I could use the USB connection.</li>
</ol>
<p>But, it is not that I want to do :</p>
<ol>
<li>Tablet off, connect the device<br></li>
<li>switch tablet on<br></li>
<li>Launch manualy the application<br></li>
<li>Initialise the usb connection with the device.<br></li>
</ol>
<p>The fact is, that actualy, I need to unconnect/connect manualy the usb on my tablet to have the connection, but me, in my case, the device will be already connected to the tablet, then i need to initialise the connection without unconnect/reconnect the usb.</p>
<p>I have tryed the example provided by Google on the USB Host connexion page that speak about Broadcast receiver, but that don't work, or I don't understant it very well.</p>
<p>My questions is:<br>
Is there any method to open the connection to an usb host device, that is already connected ?
<br>By witch way I need to search to find this dammed solution :D</p>
<p>Here the code that is already implemented to help at understand my problem :</p>
<p>manifest.xml :</p>

<p>And at the end my method that allow to make the connection :</p>
<pre><code>protected void open(Object o) throws DeviceException {

phpmyadmin ignores config.inc.php
|
<p>I have a phpmyadmin installation on a Debian Server and it seems to me like phpmyadmin is ignoring the /etc/phpmyadmin/config.inc.php.</p>
<p>I created a user which should only be able to read one database. When I login to phpmyadmin I get the error message:</p>
<pre><code>Connection for controluser as defined in your configuration failed.
</code></pre>
<p>So I checked the configuration file. In my case it should be /etc/phpmyadmin/config.inc.php</p>
<p>Right now (after many changes) this file contains this:</p>
<pre><code>$i = 0;

<p>The access permission to this file is set like this:</p>

<p>I changed the ownership of this file to www-data:www-data without success.
I am able to login as user phpmyadmin and edit the database via phpmyadmin, so the credentials should be ok.
I created and inserted the user pma with no success.</p>

<p>The problem is now, that when I login as the user with read access only, I am not able to browse any database. If I try I get the error:</p>
<pre><code>#1142 - INSERT,DELETE command denied to user xxx for table 'pma__recent'

<p>I have to give the user access to the db phpmyadmin to be able to read the database. Which I do not want to.</p>
<p>After giving access to phpmyadmin database I tried to at least hide the database. Without success.</p>
<p>I read the whole internet, I tried everything, I checked everything. Or apparently not.</p>
<p>Is there a way (log file, debug mode, whatever) to check if the config file and which config file is proceeded by phpmyadmin?</p>

MVC5 app not working in IIS 7 - Error 404 - File or directory not found
|
<p>there! </p>
<p>After some comings and goings, I finally got my very first MVC app working in my dev machine. </p>
<p>The scenario is as following: </p>
<ul>
<li>it's an intranet app (therefore I'm using Windows Authentication)</li>
<li>it's a MVC 5 app (with Bootstrap and jQuery stuff - no .aspx pages)</li>
<li>Entity Framework 6 (Code First)</li>
<li>SQL Server Compact Edition</li>
<li>VS 2013 Express Edition </li>
<li>Server: Windows 2008 R2, running IIS 7 </li>
<li>Hotfix KB980368 installed </li>
<li>IIS registered with asp.net (command aspnet_regiis.exe -i ran) </li>
</ul>
<p>I have some administrative rights on server, so I created a folder to hold the app. Then, using the VS2013, I published the app according to the following configuration:</p>
<ul>
<li>Publish method: File System</li>
<li>Target location: the folder created on server</li>
<li>Configuration: Release</li>
<li>Databases: database publishing is not supported for this publish method</li>
</ul>
<p>The target on server was filled with the following folders: </p>
<ul>
<li>bin (System.Web.MVC, System.Web.Razor, etc )</li>
<li>Content</li>
<li>fonts</li>
<li>Scripts</li>
<li>Views</li>
</ul>
<p>and the following files: </p>
<ul>
<li>Global.asax </li>
<li>packages.config </li>
<li>web.config </li>
</ul>
<p>In IIS 7 I added a Virtual Directory with the Physical Path pointing to that folder previously created. After that I converted the virtual directory to Application. </p>
<p>Tried to run the app and got a weird startIndex error. Then I noticed the App_Data folder was not created. So i corrected that, re-run the app and by this time the databases were created and the default route was properly executed, rendering the main View. </p>
<p>All the views in the app are based upon this _Layout.cshtml, where there is a navbar with some navigating links and dropdown menus. One of these is a simple element that links to the Contact View: </p>
<pre><code><a href="/Home/Contact">Contact</a>
</code></pre>
<p>Well, when I click this element I get a <em>404 - File or directory not found</em> error. And so with all others links. I tried to explicitly write the route at the address bar of the browser and the Contact view was rendered. Of course, user is not supposed to know how to write the routes. For this we create the <em>navbars</em>, links and so on. </p>
<p>Then I began to <em>google</em> for this issue and since then I've read hundreds of articles, posts, pages ... On many of them it was mentioned that this issue would be simply solved adding a couple of lines on web.config, like <a href="https://stackoverflow.com/questions/12495346/asp-net-4-5-mvc-4-not-working-on-windows-server-2008-iis-7/16577694#16577694">this one</a>. I tried. Didn't work. </p>
<p>So, in IIS 7 the configuration is the following:</p>
<ul>
<li>Application Pool: <em>Framework</em>: v4.0.30319, <em>Managed Pipeline</em>: Integrated, <em>Identity</em>: ApplicationPoolApplication</li>
<li>.NET Authorization Rules: Allow All Users</li>
<li>.NET Trust Levels: Full (internal)</li>
<li>Application Settings: <em>ClientValidationEnabled</em>: true, <em>UnobtrusiveJavaScriptEnabled</em>: true, <em>webpages:Enabled</em>: false, <em>webpages:Version</em>: 3.0.0.0</li>
<li>Connection Strings: <em>DbControleDeAcesso</em>: Data Source=|DataDirectory|\ControleDeAcesso.sdf; <em>DbOrcamento</em>: Data Source=|Data Directory|\Orcamento.sdf</li>
<li>Authentication: <em>Anonymous Authentication</em>: Disabled, <em>ASP.NET Impersonation</em>: Disabled, <em>Forms Authentication</em>: Disabled, <em>Windows Authentication</em>: Enabled</li>
<li>Handler Mappings
<ul>
<li>ExtensiolessUrlHandler-Integrated-4.0
<ul>
<li>Path: *.</li>
<li>State: Enabled</li>
<li>Path Type: Unspecified</li>
<li>Handler: System.Web.Handlers.TransferRequestHandler</li>
<li>Entry Type: Local</li>
</ul></li>
<li>ExtensiolessUrlHandler-ISAP-4.0_32bit/64bit
<ul>
<li>Path: *.</li>
<li>State: Enabled</li>
<li>Path Type: Unspecified</li>
<li>Handler: IsapiModule</li>
<li>Entry Type: Inherited</li>
</ul></li>
</ul></li>
<li>Modules
<ul>
<li>UrlRoutingModule-4.0
<ul>
<li>Code: System.Web.RoutingModule</li>
<li>Module Type: Managed</li>
<li>Entry Type: Local</li>

Change input shape dimensions for ResNet model (pytorch)
|
<p>I want to feed my <strong>3,320,320 pictures</strong> in an existing ResNet model. The model actually <strong>expects input of size 3,32,32</strong>. As I am afraid of loosing information I don't simply want to resize my pictures.
What is the best way to preprocess my images, so that they are able to run on the ResNet34?
Should I add additional layers in the forward method of ResNet? If yes, what would be a suitable combination in my case?</p>

Unhandled Exception Error in Java even with try-catch
|
<p>I am quite new to Java and started learning on YouTube. To practice GUI Programs, I decided to make my own and am now trying to resize an image to add to a button in my aplication. I searched how to resize images and found some source code online which I decided to test and put in my own program, but when I call the method I get an <code>unreported exception java.io.IOException; must be caught or declared to be thrown</code> error and the IntelliJ IDE says <code>Unhandled exception: java.io.IOException</code>. I have the <code>try-catch</code> blocks in my code, but this still comes up. How can I fix this? Here is some of my code:</p>
<p><code>Images.java</code> (class with the resizer method I found online) the <code>try-catch</code> I put in myself.</p>
<pre><code>import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class Images {
//Image resizer method for scaling images
void resizeImage(String inputImagePath, String outputImagePath, int scaledWidth, int scaledHeight) throws IOException {
//reads input image
File inputFile = new File(inputImagePath);
BufferedImage inputImage = ImageIO.read(inputFile);
//creates output image
BufferedImage outputImage = new BufferedImagee(scaledWidth, scaledHeight, inputImage.getType());
//scales the inputImage to the output image
Graphics2D g2d = outputImage.createGraphics();
g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
g2d.dispose();
// extracts extension of output file
String formatName = outputImagePath.substring(outputImagePath.lastIndexOf(".") + 1);
//writes to output file
ImageIO.write(outputImage, formatName, new File(outputImagePath));
try {
inputFile = null;
inputImage = ImageIO.read(inputFile);
}
catch(IOException e){
e.printStackTrace();
System.out.println("image file path is null");

algorithm - Coin change in java
|
<p>I have seen quite many coin change problems and this one is quite unique. I tried using DP and recursion but I wasn't able to solve it. </p>
<p>This is the problem:</p>
<p>Let's say given a price, X, where X is in cents and I have 5 finite coin denominations, 1,5,10,20,50. I have different number of 1,5,10,20,50-cent coins. I want to make price X with the maximum number of coins. How do I do it?(Assuming X can always be made with the coins at hand)</p>
<p>For example, if price X = 52 and</p>
<p>i have 3 of 1-cent coins</p>
<p>I have 4 of 5-cent coins</p>
<p>I have 8 of 10-cent coins</p>
<p>I have 6 of 20-cent coins</p>
<p>I have 4 of 50-cent coins</p>
<p>I want to find the maximum number of coins and number of ways that can be used to make this price, in this case: two 1-cent, four 5-cent, 3 10-cent coins will be the answer. </p>
<p>I have thought of a usable algorithm where first, I put the number and value of each coin into an arraylist, then I pass the array list into a recursive function that will:</p>
<p>First, deduct the price with the smallest denomination, then add 1 to int max, where max = number of coins currently used. Then, recursively call the function with price=price-smallest denomination.</p>
<p>Second, I'll recursively call the function by taking the next smallest available denomination. </p>
<p>My base cases are that if</p>
<pre><code>1) price <0, return 0
2) if price ==0 and max=currMax, return 1
3) if price>0, recursively call the 2 recursions listed above
</code></pre>
<p>EDIT: to add in code.</p>
<p>I modified the question a little bit. </p>
<pre><code> 1 import java.util.*;
2 public class CountingChange{
3 int max = 0; //maximum number of way to pay price
4 int way = 0; //number of ways to make price

9 for (int i = 0; i <5; i++){
10 int coin = sc.nextInt();
11 coins.add(i,coin);
12 }
13 int currMax = 0;
14 counter(price,coins,currMax);
15 System.out.println(String.valueOf(max) + " " + String.valueOf(way)); //output eg: 10 5, where 10 = max coins, 5 = ways
16 }
17 private void counter(int price,ArrayList<Integer> coins,int currMax){
18 currMax += 1;
19 if (coins.size()==0) return;
else if((coins.get(0)<0)||(price<0)){
20 //check if AL is empty(no way to make change), smallest coin < 0(invalid), price<0(invalid)
21 return;
22 }
23 else if (price==0){//successful change made
24 if (currMax==max){ //check max coins used
25 way+=1;
26 }
27 else if (currMax>max){
28 way = 1;
29 max = currMax;
30 }
31 }
32 else if(price>0){
33 coins.set(0,coins.get(0)-1);//use smallest coin
34 counter(price-coins.get(0),coins,currMax);

38 }
39 public static void main(String[] args){
40 CountingChange myCountingChange = new CountingChange();
41 myCountingChange.run();
42 }
43 }
</code></pre>
<p>I believe my problem is that I was deducting the number of coins(instead of the value of coin) used to make the price. But I really have no idea how to use a suitable//what kind of data structure to store my coins and its value.</p>

Python: How can we smooth a noisy signal using moving average?
|
<p>For an evaluation of a random forest regression, I am trying to improve a result using a <code>moving average filter</code> after fitting a model using a <code>RandomForestRegressor</code> for a dataset found in <a href="https://drive.google.com/open?id=0B2Iv8dfU4fTUdlE0VUJKUnctSkE" rel="nofollow noreferrer">this link</a></p>
<pre><code>import pandas as pd

n_features=3000
df = pd.read_csv('cubic32.csv')

df.dropna(inplace=True)

parameters = {'n_estimators': [10]}
clf_rf = RandomForestRegressor(random_state=1)

</code></pre>
<p>However, the plot of the predicted values seems (as shown below) to be very coarse (the blue line) even if i am smoothing the prediction values like the following</p>
<pre><code>smoothed = np.convolve(modelPred_test, np.ones(10)/10)
</code></pre>
<p>The orange line is a plot of the actual value.</p>
<p><a href="https://i.stack.imgur.com/oXDN0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oXDN0.png" alt="enter image description here"></a></p>
<p>Is there any way that we can penalize the prediction error (or smooth the noise of the signal using a moving average or other smoothing techniques) so that we get a plot closer to the actual value? I am also trying to increase the number of estimators for the random forest tree (<code>n_estimators</code>), but it doesn't seem to improve much. If we plot the actual value alone, it looks like the following.</p>

How to update the same component with different params in Angular
|
<p>I've done the <a href="https://angular.io/tutorial" rel="nofollow noreferrer">tour of heroes</a> from angular. It works perfectly. </p>
<p>Now I want to put the dashboard component in the hero detail view. So it shows me the top of heroes, and after that, the hero detail view.
<a href="https://i.stack.imgur.com/yGDt1.png" rel="nofollow noreferrer">Image</a> </p>
<p>I have a Router link that loads the same component, but with different params. I want to know, what to do so that when I click on any element from the dashboard this one load a different hero. </p>
<p><strong>This is the code of the hero-detail.component.html</strong></p>
<pre><code><app-dashboard></app-dashboard>
<div *ngIf="hero">
<h2>{{ hero.name | uppercase }} Details</h2>
<div><span>id: </span>{{hero.id}}</div>
<div>
<label>name:
</label>
<div><span>name: </span>{{hero.name}}</div>
</div>
<button (click)="goBack()">go back</button>
<button (click)="save()">save</button>
</div>
</code></pre>
<p><strong>hero detail class</strong></p>
<pre><code>export class HeroDetailComponent implements OnInit {
@Input() hero: Hero;
constructor(
private route: ActivatedRoute,
private heroService: HeroService,
private location: Location
) {}
ngOnInit(): void {
this.getHero();
}
getHero(): void {
const id = +this.route.snapshot.paramMap.get('id');
this.heroService.getHero(id)
.subscribe(hero => this.hero = hero);
}
goBack(): void {
this.location.back();
}
save(): void {
this.heroService.updateHero(this.hero)
.subscribe(() => this.goBack());
}
}
</code></pre>
<p><strong>The dashboard code</strong></p>
<pre><code><a *ngFor="let hero of heroes" class="col-1-4" routerLink="/detail/{{hero.id}}">
<div class="module hero">
<h4>{{hero.name}}</h4>
</div>
</a>
</code></pre>
<p><strong>The router is the same as the tutorial.</strong> </p>
<pre><code>const routes: Routes = [
{ path: '', redirectTo: '/dashboard', pathMatch: 'full' },
{ path: 'dashboard', component: DashboardComponent },
{ path: 'heroes', component: HeroesComponent },
{ path: 'detail/:id', component: HeroDetailComponent }
];
</code></pre>
<p><strong>A bad solution:</strong></p>
<p>After research a little i found the possibility to add the <em>(click)="reloadRoute()"</em> to the link, but this one refresh all the page. </p>
<pre><code><a *ngFor="let hero of heroes" class="col-1-4" routerLink="/detail/{{hero.id}}" (click)="reloadRoute()">
<div class="module hero">
<h4>{{hero.name}}</h4>
</div>

<p>I was hoping for C++ hough transform to ace python but what happened was actually opposite.</p>

<p>Even though C++ ran the complete program ~2X faster it is very slow in hough transform. Why is it so? This is very counter intuitive. What am I missing here?</p>

Dagger 2: multi-module project, inject dependency but get "lateinit property repository has not been initialize" error at runtime
|
<p>Dagger version is 2.25.2.</p>
<p>I have two Android project modules: <code>core</code> module & <code>app</code> module. </p>
<p>In <code>core</code> module, I defined for dagger <code>CoreComponent</code> , </p>
<p>In <code>app</code> module I have <code>AppComponent</code> for dagger.</p>
<p><code>CoreComponet</code> in core project module:</p>
<pre><code>@Component(modules = [MyModule::class])
@CoreScope
interface CoreComponent {
fun getMyRepository(): MyRepository
}
</code></pre>
<p>In core project module, I have a repository class, it doesn't belong to any dagger module but I use <code>@Inject</code> annotation next to its constructor:</p>
<pre><code>class MyRepository @Inject constructor() {
...
}
</code></pre>
<p>My app component:</p>
<pre><code>@Component(modules = [AppModule::class], dependencies = [CoreComponent::class])
@featureScope
interface AppComponent {
fun inject(activity: MainActivity)
}
</code></pre>
<p>In <code>MainActivity</code>:</p>
<pre><code>class MainActivity: AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val coreComponent = DaggerCoreComponent.builder().build()
DaggerAppComponent
.builder()
.coreComponent(coreComponent)
.build()
.inject(this)
}
}
</code></pre>
<p>My project is MVVM architecture, In general:</p>
<ul>
<li><p><code>MainActivity</code> hosts <code>MyFragment</code></p></li>
<li><p><code>MyFragment</code> has a reference to <code>MyViewModel</code> </p></li>
<li><p><code>MyViewModel</code> has dependency <code>MyRepository</code> (as mentioned above <code>MyRepository</code> is in <code>core</code> module)</p></li>
</ul>
<p>Here is <code>MyViewModel</code> :</p>
<pre><code>class MyViewModel : ViewModel() {
// Runtime error: lateinit property repository has not been initialize
@Inject
lateinit var repository: MyRepository
val data = repository.getData()
}
</code></pre>
<p><code>MyViewModel</code> is initialized in MyFragment:</p>
<pre><code>class MyFragment : Fragment() {
lateinit var viewModel: MyViewModel
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
viewModel = ViewModelProviders.of(this).get(MyViewModel::class.java)
...
}
}
</code></pre>
<p>When I run my app, it crashes with runtime error:</p>
<pre><code>kotlin.UninitializedPropertyAccessException: lateinit property repository has not been initialize
</code></pre>
<p>The error tells me dagger dependency injection does't work with my setup. So, what do I miss? How to get rid of this error?</p>
<p><strong>==== update =====</strong></p>
<p>I tried :</p>
<pre><code>class MyViewModel @Inject constructor(private val repository: MyRepository): ViewModel() {
val data = repository.getData()
}
</code></pre>
<p>Now when I run the app, I get new error:</p>
<pre><code>Caused by: java.lang.InstantiationException: class foo.bar.MyViewModel has no zero argument constructor
</code></pre>
<p><strong>====== update 2 =====</strong></p>
<p>Now, I created <code>MyViewModelFactory</code>:</p>
<pre><code>class MyViewModelFactory @Inject constructor(private val creators: Map<Class<out ViewModel>,
@JvmSuppressWildcards Provider<ViewModel>>): ViewModelProvider.Factory {
override fun <T : ViewModel> create(modelClass: Class<T>): T {
val creator = creators[modelClass] ?: creators.entries.firstOrNull {
modelClass.isAssignableFrom(it.key)
}?.value ?: throw IllegalArgumentException("unknown model class $modelClass")
try {
@Suppress("UNCHECKED_CAST")
return creator.get() as T
} catch (e: Exception) {
throw RuntimeException(e)
}
}
}
</code></pre>
<p>I updated MyFragment to be :</p>
<pre><code>class MyFragment : Fragment() {
lateinit var viewModel: MyViewModel
@Inject
lateinit var viewModelFactory: ViewModelProvider.Factory
override fun onAttach(context: Context) {
// inject app component in MyFragment
super.onAttach(context)
(context.applicationContext as MyApplication).appComponent.inject(this)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
// I pass `viewModelFactory` instance here, new error here at runtime, complaining viewModelFactory has not been initialized
viewModel = ViewModelProviders.of(this, viewModelFactory).get(MyViewModel::class.java)
...
}
}
</code></pre>
<p>Now I run my app, I get new error:</p>
<pre><code>kotlin.UninitializedPropertyAccessException: lateinit property viewModelFactory has not been initialized
</code></pre>
<p>What's still missing?</p>

Passing a dictionary key value in payload for a python request API

AHK: Assign hotkey only for one specific active window and not for others
|
<p>I have just done a piece of code that does the following thing. When I make a selection by mouse in Firefox or EndNote, the script sents a Ctrl+c and checks the clipboard for a regex match. If there is a match, it changes the clipboard contents and shows a tooltip. It works fine for these two programs. Adobe Acrobat sometimes shows an error when a Ctrl+c is sent (even if a user presses a ctrl-c Acrobat sometimes shows famous "There was an error while copying to the Clipboard. An internal error occurred). So it decided to assign an F9 hotkey, but it works for all programs and not just for Acrobat. How do I assign an hotkey for only one window – Acrobat? Here's my code. I know it's lame – I am a newbie to programming in general, and in AHK in particular.</p>
<pre><code>#If WinActive("ahk_exe firefox.exe") || WinActive("ahk_exe EndNote.exe") || WinActive("ahk_exe Acrobat.exe")

Add my own bundle sources to pax-exam when building with pax-maven-plugin
|
<p>I'm trying to build my OSGI bundle with <a href="http://www.ops4j.org/projects/pax/construct/maven-pax-plugin/" rel="nofollow noreferrer">pax-maven-build</a> and in the same time test it with <a href="http://team.ops4j.org/wiki/display/paxexam/Pax+Exam" rel="nofollow noreferrer">pax-exam</a>. It have some bundle in provision than I can test with the following pax-exam test configuration:</p>
<pre><code>@RunWith(JUnit4TestRunner.class)
@ExamReactorStrategy(AllConfinedStagedReactorFactory.class)
public class OSGILoaderTest {
@Inject
protected BundleContext bundleContext;
@Configuration
public Option[] config() throws MalformedURLException {
String projectRoot = // a path to my project
return options(
junitBundles(),
equinox(),
bundle(projectRoot + "libs/org.eclipse.core.variables_3.2.500.v20110511.jar"),
bundle(projectRoot + "libs/org.eclipse.core.contenttype_3.4.100.v20110423-0524.jar"),
bundle(projectRoot + "libs/org.eclipse.core.expressions_3.4.300.v20110228.jar"),
// etc...
);
}
@Test
public void getBundleContext() throws RodinDBException {
IRodinDB rodinDB = RodinCore.getRodinDB();
assertNotNull(rodinDB);
}
}
</code></pre>
<p>Here, I can see I can access to the IRodinDB instance from a jar I have provisonned.</p>
<p>Now I have code my own bundle, which is going to use all the jar provisionned. But I cannot even test my own code, for instance:</p>
<pre><code>@Test
public void checkAccessToRodinDbTest() {
VTGService service = null;
assertTrue(true);
}
</code></pre>
<p>give an error <strong>at compilation time</strong>:</p>
<blockquote>
<p>[ERROR] Failed to execute goal org.ops4j:maven-pax-plugin:1.5:testCompile (default-testCompile) : Compilation failure</p>
<p>[ERROR] cannot find symbol</p>
<p>[ERROR] symbol : class VTGService</p>
</blockquote>
<p>It seems test compilation cannot see 'src/main/java', contrarly as expected by the default behavior of maven-compiler-plugin. But in my case, you can see than maven does not use the compiler plugin but instead maven-pax-plugin.</p>
<p>The question is: how can i test my own bundle with pax-exam ?</p>
<p><strong>update1</strong></p>
<p>It seems that this is a problem with recent version of maven-pax-plugin, as <a href="http://www.ops4j.org/projects/pax/construct/maven-pax-plugin/usage.html" rel="nofollow noreferrer">the basic example available in ops4j pax maven plugin</a> (in section <em>Using the Pax Plugin inside a POM</em>) seems to suffer of the same problem.</p>
<p><strong>update2</strong></p>
<p>As requested by Dmytro, this is the pom.xml of my bundle:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>

<hr />
<p>I am not sure it is the most elegant solution, but I created a new maven project when I can import my own bundle like in the source code of my question.</p>
<p>Is there an elegant way to add my own java sources directly as new bundle for test in the same Maven project ? It could be not possible (as the bundle assembly operation is done <strong>after</strong> the compilation and tests)...</p>

net.sf.json.JSONException

<p>I converted a normal JavaScript <code>array</code> (which is in one JSP page), did a <code>JSON.stringify()</code> to that array and passed it across to another JSP as a parameter. In the other JSP, I'm reading it using <code>request.getParameter()</code>.</p>
<p>Now, while converting the string to a <code>JSONArray</code>, I'm getting an exception like this-</p>

Issues getting CasperJS to upload image to file field - tried CasperJS fill() and PhantomJS uploadFile()
|
<p>I'm trying to use CasperJS to upload images to a web-form.</p>
<p>My form looks something like this:</p>
<pre><code><form action="" method="POST" enctype="multipart/form-data" class="form-vertical">
...
<legend>Campaign Banner</legend>
<div class="control-group image-field ">
<label class="control-label">Now Large</label>
<div class="controls">
<div class="file-field"><input id="id_now_large_image" name="now_large_image" type="file"></div>
<div class="image-preview"></div>

</div>
</div>
<div class="control-group image-field ">

<div class="controls">
<div class="file-field"><input id="id_now_medium_image" name="now_medium_image" type="file"></div>
<div class="image-preview"></div>
<div class="clear"></div>

<div class="image-preview now-small"></div>
<div class="clear"></div>
<span class="help-inline"></span>
</div>
</div>
</code></pre>
<p>The submit button looks like this:</p>
<pre><code><div class="form-actions">
<button type="submit" class="btn btn-small ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false"><span class="ui-button-text">Save changes</span></button>
</div>
</code></pre>
<p>I've put a Gist of the full HTML here: <a href="https://gist.github.com/victorhooi/8277035" rel="nofollow noreferrer">https://gist.github.com/victorhooi/8277035</a></p>
<p>First, I've tried using CasperJS's <a href="http://docs.casperjs.org/en/latest/modules/casper.html#fillxpath" rel="nofollow noreferrer">fill</a> method:</p>
<pre><code> this.fill('form.form-vertical', {
'now_large_image': '/Users/victor/Dropbox/CMT Test Resources/Test Banners/Default Banners/now_large.jpg',
}, false);
this.click(x('//*[@id="content-wrapper"]//button/span'));
</code></pre>
<p>I also did a this.capture(), and I saw that the file field had been filled in:</p>
<p><img src="https://i.stack.imgur.com/o1vF7.png" alt="enter image description here"></p>
<p>I'm not using the fill method's inbuilt submit, but I'm clicking on the submit button myself:</p>
<p>this.click(x('//*[@id="content-wrapper"]//button/span'));</p>
<p>I then do another capture, and I can see that the form has been submitted:</p>
<p><img src="https://i.stack.imgur.com/X9FDl.png" alt="enter image description here"></p>
<p>However, the image doesn't seem to have been uploaded at all.</p>
<p>I've also tried using PhantomJS's <a href="http://phantomjs.org/api/webpage/method/upload-file.html" rel="nofollow noreferrer">uploadFile()</a> method:</p>
<pre><code>this.page.uploadFile('input[name=now_large_image]', '/Users/victor/Dropbox/CMT Test Resources/Test Banners/Default Banners/now_large.jpg');
</code></pre>
<p>and then clicking on the submit button as well.</p>
<p>Same issue - the form field gets filled in - however, the image itself doesn't seem to get submitted.</p>
<p>Any ideas on how I can get the images to upload correctly here?</p>

Verilog ,cannot be assigned more than one value

MVC 3 Get result from partial view into model
|
<p>I'm sure this is easy, but maybe I haven't searched well ...</p>
<p>I want to know how to get results from a partial view back to the model and/or controller.</p>
<p>If the user enters a FirstName, Gender (from drop down) and Grade (from drop down), I only find then FirstName and Gender in the model. I want to know how to get the Grade from the drop down in the partial view all the way back into the model, so I can see it in the controller.</p>
<p>Please look for this question in the controller code:</p>
<blockquote>
<blockquote>
<blockquote>
<blockquote>
<blockquote>
<p>What do I need to do to get the GradeLevel from the partial class to be here: <<<<<</p>
</blockquote>
</blockquote>
</blockquote>
</blockquote>
</blockquote>
<p>Note: this is not the exact code. There may be small, insignificant typo's.</p>
<p>EDIT: Apparently you can't add a long comment, so I will add here:</p>
<p>Thank you, Tom and Mystere Man. Tom got me thinking as to why it doesn't work. I didn't think through the model binding. With the design I proposed, the HTML gets rendered and the Grade drop down has this id: "Grade". The property on the model I want to bind to is: "GradeLevelID". If I change the helper in the partial view to be @Html.DropDownList("GradeLevelID" ... it works perfectly. </p>
<p>But that is not a good solution. My idea was to abstract the partial view from the main view. Hard coding the name blows that! I did work up a slightly improved solution. In the main view, I change the @Html.Partial statement to pass the model property name to the partial. Like such:</p>
<pre><code>@Html.Partial("GradeDropDown", (SelectList)Model.GradeSelectList, new ViewDataDictionary { { "modelPropertyName", "GradeLevelID" } })
</code></pre>
<p>Then I could change the partial view to say </p>
<pre><code>@model System.Web.Mvc.SelectList
@Html.DropDownList((string)ViewData["modelPropertyName"], Model)
</code></pre>
<p>But that also seems like a goofy way to approach things. Thanks for the help. I'll look at EditorTemplates.</p>

iphone EXC_BAD_ACCESS with NSMutableArray
|
<p>Ok so I have a UIViewTable and a UISearchBar with two scope buttons. The idea being that when I press a scope button the datasource for UIViewTable gets changed but I am getting
EXC_BAD_ACCESS error.</p>
<p>I have the following code in my UIViewController SearchViewController.m:</p>
<pre><code>- (void)searchBar:(UISearchBar *)searchBar selectedScopeButtonIndexDidChange: (NSInteger) selected scope
{
MyAppDelegate *delegate = (MyAppDelegate *) [[UIApplicationsharedApplication] delegate];
if (self.listData != nil) {
[self.listData release];
}
if (selectedScope == 0) {
self.listData = [delegate.data getListOne];
}
else {
self.listData = [delegate.data getListTwo];
}
}
- (void) viewDidLoad {
MyAppDelegate *delegate = (MyAppDelegate*) [[UIApplication sharedApplication] delegate];
self.listData = [delegate.data getListOne];
//some other unrelated code
}
</code></pre>
<p>in my SearchViewController.h I have:</p>
<pre><code>@property (nonatomic,retain) NSMutableArray *listData;
</code></pre>
<p>in my Data.m I have:</p>
<pre><code>-(NSMutableArray *) getListOne {
NSMutableArray *list = [[NSMutableArray alloc] initWithObjects:@"test1",
@"test2",
nil];
[list autorelease];
return list;
}
-(NSMutableArray *) getListTwo {
NSMutableArray *list = [[NSMutableArray alloc] initWithObjects:@"test3",
@"test4",
nil];
[list autorelease];
return list;
}
</code></pre>
<p>It crashes on:</p>
<pre><code>self.listData = [delegate.data getListTwo];
</code></pre>
<p>I checked that its when I am setting the property that it crashes. My understanding is that when I create the new NSMutableArray in Data.m I assign it autorelease as I should. </p>
<p>When the view loads I assign it to my listData and since I am accessing the property which has retain then the reference count is incremented (so its now 2 pending auto release).</p>
<p>When I press the button to change the data source I check too see if listData exists (which it always will), release it so that the old NSMutableArray counter will be 0 (assuming autorelease has occured). </p>
<p>Then I get a new NSMutableArray and set it to this property... is my understanding correct? I have spent far too long on this simple problem :(</p>
<p>oh also I did create another NSMutableArray that was not connected to the tableView and still get the same problem, also if I don't release it in my if statement the problem does not exist but I will then have a memory leak?? I could always just keep the array and remove/add objects but I want to know why this is not working :)
cheers</p>

ArrayList error - Cannot find symbol

<p>I see that there is some problem with save() method. Also stackoverflow is thrown on delete() method.</p>
<p>I've already found the solution. My problem disappears when I change name of interface that extends Repository interface to (for example) JpaUserRepository.</p>
<p>So, the question is "What is going on". Why stackoverflow is thrown when interface name that implements spring data repository matches pattern <em>Classname</em>Repository?</p>

Easy way to add a drawer item with custom onPress?
|
<p>I'm using DrawerNavigator and, as long as I want to navigate to a new screen, all's fine.</p>
<p>Now I want to add a drawer item which does not navigate to a new screen but simply triggers an action (in general). Specifically, I want to use 'react-native' Share functionality.</p>
<p>I got this to work but I think the solution is not a very good one. Here's what I got so far:</p>
<pre class="lang-jsx prettyprint-override"><code>const myContentComponent = props => (
<ScrollView alwaysBounceVertical={false}>
<SafeAreaView style={{ flex: 1 }} forceInset={{ top: 'always', horizontal: 'never' }}>
<DrawerItems {...props} />
<TouchableItem
key="share"
onPress={() => {
Share.share(
{
message: 'YO: this will be the text message',
url: 'http://tmp.com',
title: 'This will be the email title/subject',
},
{
// Android only:
dialogTitle: 'This will be the title in the dialog to choose means of sharing',
},
);
props.navigation.navigate('DrawerClose');
}}
delayPressIn={0}
>
<SafeAreaView forceInset={{ left: 'always', right: 'never', vertical: 'never' }}>
<View style={[{ flexDirection: 'row', alignItems: 'center' }, {}]}>
<View style={[{ marginHorizontal: 16, width: 24, alignItems: 'center' }, { opacity: 0.62 }, {}]}>
<Icon name="share" />
</View>
<Text style={[{ margin: 16, fontWeight: 'bold' }, { color: DrawerItems.defaultProps.inactiveTintColor }]}>Share</Text>
</View>
</SafeAreaView>
</TouchableItem>
</SafeAreaView>
</ScrollView>
);
const RootStack = DrawerNavigator(
{
Settings: {
screen: SettingsScreen,
},
},
{
contentComponent: myContentComponent,
},
);
</code></pre>
<p>Basically, I am creating a new <code>contentComponent</code> based off of the default:</p>
<p><a href="https://github.com/react-navigation/react-navigation/blob/v1.5.8/src/navigators/DrawerNavigator.js#L16-L22" rel="noreferrer">https://github.com/react-navigation/react-navigation/blob/v1.5.8/src/navigators/DrawerNavigator.js#L16-L22</a></p>
<p>I am copying the styles and element structure of a normal drawer item (everything under <code>TouchableItem</code>) - all this so I can define my own <code>onPress</code> which does the share logic and closes the drawer.</p>
<p>There has to be a better way right? What happens if I want the "Share" drawer item somewhere amongst the drawer items rendered by <code>DrawerItems</code> (the ones that support navigation)? Right now I can only work around the items rendered by <code>DrawerItems</code>. Besides, copying so much code from react-navigation seems like really bad form.</p>
<p>I just want an item which does some custom logic instead of rendering a screen.</p>

null value in findcontrol of gridview, item template confusion
|
<p>I have Template Field for gridview as below:</p>
<pre><code><asp:TemplateField ShowHeader="False">
<EditItemTemplate>
<asp:TextBox ID="txtEmpName" runat="server"></asp:TextBox>
<asp:TextBox ID="txtBonus" runat="server"></asp:TextBox>
<asp:TextBox ID="txtID" runat="server"></asp:TextBox>
</EditItemTemplate>
<EditItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True"
CommandName="Update" Text="Update"></asp:LinkButton>
&nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False"
CommandName="Cancel" Text="Cancel"></asp:LinkButton>
</EditItemTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False"
CommandName="Edit" Text="Edit"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</code></pre>
<p>When i am in <code>gv_RowUpdating</code> event, i wanted to take the value of edited field by findcontrol.</p>
<p>For that i am using following code:</p>
<pre><code>`TextBox txtUname = (TextBox)gv.Rows[e.RowIndex].FindControl("txtEmpName");`
</code></pre>
<p>But each time it is showing me <code>null</code> value in <code>txtUname</code> when i debug the code.</p>
<p>What can be the problem?</p>
<p>Full Event Code:</p>
<pre><code> protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
try
{
TextBox txtUname = (TextBox)gv.Rows[e.RowIndex].FindControl("txtEmpName");
float bonus = float.Parse(gv.DataKeys[e.RowIndex].Values["bonus"].ToString());
try
{
cmd = new SqlCommand("update emp set empName=@eName");
cmd.parameters.AddParametersWithValue("@eName",txtUname.Text);
cmd.ExecuteNonQuery();
}
catch (Exception ex)
{
}
}
catch (Exception ex)
{
}
}
</code></pre>
<p><strong>EDIT</strong></p>
<pre><code>protected void Page_Load(object sender, EventArgs e)
{
con = new SqlConnection("Data Source=192.168.51.71;Initial Catalog=WebBasedNewSoft;User ID=sa;password=prabhu");

}
private void BindGrid()
{
try
{
da = new SqlDataAdapter("select * from emp", con);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();
}
catch (Exception ex)
{
}
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int index = GridView1.EditIndex;
GridViewRow row = GridView1.Rows[index];
string eName = ((TextBox)row.Cells[2].Controls[0]).Text.ToString().Trim();

How do I return an array from an array function using groovy?

<p>How do I return an array from an array function using Groovy? I am currently trying it with the following code but I am getting errors when I execute the code!

Two ajax updates with h:selectOneMenu f:ajax
|
<blockquote>
<p>In short, if a component has been updated by Ajax, it can not launch new events Ajax</p>
</blockquote>
<p>I have three h:selectOneMenu: A, B and C.
When I fire change event in A, then update the B h:selectOneMenu.
When I fire change event in B, then update the C h:selectOneMenu.</p>
<p>The problem is that when the content of B h:selectOneMenu is updated, the ajax in B don't work and C never can't be updated.</p>
<pre><code><h:selectOneMenu id="A" value="#{paqueteBean.mes}" label="a">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItem itemLabel="Enero" itemValue="ENERO" />
<f:selectItem itemLabel="Febrero" itemValue="FEBRERO" />
<f:ajax listener="#{paqueteBean.changeMes}" render="B" />
</h:selectOneMenu>
<h:selectOneMenu id="B" value="#{paqueteBean.origen}" label="b">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.origenes}" />
<f:ajax listener="#{paqueteBean.changeOrigen}" render="C"/>
</h:selectOneMenu>
<h:selectOneMenu id="C" value="#{paqueteBean.zona}" label="c">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.zonas}" />
</h:selectOneMenu>
</code></pre>
<p>The ajax response is good, but simply don't work after the update:</p>
<pre><code><?xml version='1.0' encoding='UTF-8'?>
<partial-response id="j_id1"><changes><update id="B"><![CDATA[<select id="B" name="b" size="1" onchange="mojarra.ab(this,event,'valueChange','@this','C')"> <option value="">Seleccione...</option>
<option value="BUE">Ezeiza o Aeroparque</option>
</select>]]></update><update id="j_id1:javax.faces.ViewState:0"><![CDATA[-2984590031183218074:6198891110668113457]]></update></changes></partial-response>
</code></pre>
<p>UPDATE!</p>
<p>With PrimeFaces I have the same behavior:</p>
<pre><code><h:form id="filtro">
<p:selectOneMenu id="A" value="#{paqueteBean.mes}">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItem itemLabel="Enero" itemValue="ENERO" />
<f:selectItem itemLabel="Febrero" itemValue="FEBRERO" />
<f:selectItem itemLabel="Marzo" itemValue="MARZO" />
<p:ajax listener="#{paqueteBean.changeMes}" update="B" />
</p:selectOneMenu>
<p:selectOneMenu id="B" value="#{paqueteBean.origen}"
disabled="#{empty paqueteBean.mes}">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.origenes}" />
<p:ajax listener="#{paqueteBean.changeOrigen}" update="C"
process="origen mesSalida" />
</p:selectOneMenu>
<p:selectOneMenu id="C" value="#{paqueteBean.zona}"
disabled="#{empty paqueteBean.mes or empty paqueteBean.origen}">
<f:selectItem itemLabel="Seleccione..." itemValue="" />
<f:selectItems value="#{paqueteBean.zonas}" />
</p:selectOneMenu>
</code></pre>
<p></p>
<p>When I change some A values, the method in backing bean is fired, but when I change some B value, the method in backing bean is not fired.</p>
<p>The most strange is that for items that existed in B before the ajax update, the backing bean is called.</p>
<p>Backing Bean, nothing special:</p>
<pre><code> public void changeMes(){
logger.debug("en changeMes el Mes es: " + this.mes);
this.origenes = new HashMap<String, String>();
this.origenes.put("Ezeiza o Aeroparque", "BUE");
}
public void changeOrigen(){
logger.debug("Mes: " + this.mes);
logger.debug("Origen" + this.origen);
this.zonas = new HashMap<String, String>();
this.zonas.put("Argentina", "AR");
this.zonas.put("Brasil", "BR");
}
public void changeZona(){
logger.debug("Mes: " + this.mes);
logger.debug("Origen" + this.origen);
logger.debug("Zona" + this.zona);
this.destinos = new HashMap<>();
this.destinos.put("Mar del Plata", "MDQ");
this.destinos.put("Punta Lara", "LTA");

Using ezplot with specified ordinate range

<p>I have a symbolic function that I am plotting with ezplot:</p>
<pre><code> ezplot(f, [0,1]);

<p>I could not find a way to specify the y-values (ordniate) to plot this function. However, I want f to be plotted for x in [0,1] and y in [0,1] also. Default ezplot plots my function for y in [0,20] or something like that. How can I specify the y-range?</p>

"Error converting data type nvarchar to numeric."

<p>I'm trying to create a function that returns a table with a bunch of fields.
The query used in the function inserts data to a temp table which then inserts into the returning table.
query runs fine when I run it outside of the function but when I select from the function I get "Error converting data type nvarchar to numeric." error. </p>

<p>It's probably hard to tell what the issue is from the above script but I'm looking for a way to debug where the issue is.
Strange thing is the function runs fine if I change one of the parameters (change NetworkID) which is supposed to return data in the same format.</p>
<p>Can someone help me point to where to look?</p>
<p>Thanks,</p>
<p>I've found a link to post the entire sql script. It can be found <a href="http://www.tutorialspoint.com/execute_sql_online.php?PID=0Bw_CjBb95KQMclFFaTZ2azVlMEk" rel="nofollow noreferrer">here</a></p>
