In my case, I updated one of my libraries in my android project.
I'm using Reservoir as my cache storage solution: https://github.com/anupcowkur/Reservoir
I went from:
compile 'com.anupcowkur:reservoir:2.1'
To:
compile 'com.anupcowkur:reservoir:3.1.0'
The library author must have removed the commons-io library from the repo so my app no longer worked.
I had to manually include the commons-io by adding this onto gradle:
compile 'commons-io:commons-io:2.5'
https://mvnrepository.com/artifact/commons-io/commons-io/2.5

Main class :
URL url = new URL("https://www.example.com/test.png");
URLConnection l_connection = null;
SSLContext sslcontext = SSLContext.getInstance("TLSv1.2");
sslcontext.init(null, null, null);
SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(sslcontext.getSocketFactory());
As the OP said, TLS v1.1 and v1.2 protocols are supported in API level 16+, but are not enabled by default, we just need to enable it.
Example here uses HttpsUrlConnection
, not HttpUrlConnection
. Follow https://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/, we can create a factory
class MyFactory extends SSLSocketFactory {
private javax.net.ssl.SSLSocketFactory internalSSLSocketFactory;
public MyFactory() throws KeyManagementException, NoSuchAlgorithmException {
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
internalSSLSocketFactory = context.getSocketFactory();
}
@Override
public String[] getDefaultCipherSuites() {
return internalSSLSocketFactory.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return internalSSLSocketFactory.getSupportedCipherSuites();
}
@Override
public Socket createSocket() throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket());
}
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
}
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
}
@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
}
private Socket enableTLSOnSocket(Socket socket) {
if(socket != null && (socket instanceof SSLSocket)) {
((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
}
return socket;
}
}
No matter which Networking library you use, make sure ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
gets called so the Socket has enabled TLS protocols.
Now, you can use that in HttpsUrlConnection
class MyHttpRequestTask extends AsyncTask<String,Integer,String> {
@Override
protected String doInBackground(String... params) {
String my_url = params[0];
try {
URL url = new URL(my_url);
HttpsURLConnection httpURLConnection = (HttpsURLConnection) url.openConnection();
httpURLConnection.setSSLSocketFactory(new MyFactory());
// setting the Request Method Type
httpURLConnection.setRequestMethod("GET");
// adding the headers for request
httpURLConnection.setRequestProperty("Content-Type", "application/json");
String result = readStream(httpURLConnection.getInputStream());
Log.e("My Networking", "We have data" + result.toString());
}catch (Exception e){
e.printStackTrace();
Log.e("My Networking", "Oh no, error occurred " + e.toString());
}
return null;
}
private static String readStream(InputStream is) throws IOException {
final BufferedReader reader = new BufferedReader(new InputStreamReader(is, Charset.forName("US-ASCII")));
StringBuilder total = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
total.append(line);
}
if (reader != null) {
reader.close();
}
return total.toString();
}
}
For example
new MyHttpRequestTask().execute(myUrl);
Also, remember to bump minSdkVersion
in build.gradle to 16
minSdkVersion 16
I had the same exception in the simulator (Android Studio on OSX) but connecting to the same URL on the iOS simulator worked fine... Looks like it all stemmed from the fact I'd be running the simulator whilst connected to a personal hotspot for my internet connection and then came back later while connected to wifi and the simulator didn't like the new internet connection for some reason, seems like it thought the old hotspot was the current connection, which was no longer working..
Closing and relaunching the simulator worked!
This is not the exact answer for your question, but this may help you
public class JsonParser {
private static DefaultHttpClient httpClient = ConnectionManager.getClient();
public static List<Club> getNearestClubs(double lat, double lon) {
// YOUR URL GOES HERE
String getUrl = Constants.BASE_URL + String.format("getClosestClubs?lat=%f&lon=%f", lat, lon);
List<Club> ret = new ArrayList<Club>();
HttpResponse response = null;
HttpGet getMethod = new HttpGet(getUrl);
try {
response = httpClient.execute(getMethod);
// CONVERT RESPONSE TO STRING
String result = EntityUtils.toString(response.getEntity());
// CONVERT RESPONSE STRING TO JSON ARRAY
JSONArray ja = new JSONArray(result);
// ITERATE THROUGH AND RETRIEVE CLUB FIELDS
int n = ja.length();
for (int i = 0; i < n; i++) {
// GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY
JSONObject jo = ja.getJSONObject(i);
// RETRIEVE EACH JSON OBJECT'S FIELDS
long id = jo.getLong("id");
String name = jo.getString("name");
String address = jo.getString("address");
String country = jo.getString("country");
String zip = jo.getString("zip");
double clat = jo.getDouble("lat");
double clon = jo.getDouble("lon");
String url = jo.getString("url");
String number = jo.getString("number");
// CONVERT DATA FIELDS TO CLUB OBJECT
Club c = new Club(id, name, address, country, zip, clat, clon, url, number);
ret.add(c);
}
} catch (Exception e) {
e.printStackTrace();
}
// RETURN LIST OF CLUBS
return ret;
}
}
Again, it’s relatively straight forward, but the methods I’ll make special note of are:
JSONArray ja = new JSONArray(result);
JSONObject jo = ja.getJSONObject(i);
long id = jo.getLong("id");
String name = jo.getString("name");
double clat = jo.getDouble("lat");
Using the google maps projection api to draw the polylines on an overlay view enables us to do a lot of things. Check this repo that has an example.
Write below code into your MainActivity file after setContentView(R.layout.activity_main);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
And below import statement into your java file.
import android.os.StrictMode;
In WCF serive project this issue may be due to Reference of System.Web.Mvc.dll 's different version or may be any other DLL's different version issue. So this may be compatibility issue of DLL's different version
When I use
System.Web.Mvc.dll version 5.2.2.0 -> it thorows the Error The content type text/html; charset=utf-8 of the response message
but when I use
System.Web.Mvc.dll version 4.0.0.0 or lower -> That's works fine in my project and not have an Error.
I don't know the reason of this different version of DLL's issue but when I change the DLL's verison which is compatible with your WCF Project than it works fine.
This Error even generate when you add reference of other Project in your WCF Project and this reference project has different version of System.Web.Mvc DLL or could be any other DLL.
If your software uses a ProxySelector
(for example for using a PAC-script instead of a static host/port) and your HTTPComponents is version 4.3 or above then you can use your ProxySelector
for your HttpClient
like this:
ProxySelector myProxySelector = ...;
HttpClient myHttpClient = HttpClientBuilder.create().setRoutePlanner(new SystemDefaultRoutePlanner(myProxySelector))).build();
And then do your requests as usual:
HttpGet myRequest = new HttpGet("/");
myHttpClient.execute(myRequest);
I have also come across this issue whilst upgrading from Java 1.6_29 to 1.7.
Alarmingly, my customer has discovered a setting in the Java control panel which resolves this.
In the Advanced Tab you can check 'Use SSL 2.0 compatible ClientHello format'.
This seems to resolve the issue.
We are using Java applets in an Internet Explorer browser.
Hope this helps.
have you tried doing it without the JSON object and just passed two basicnamevaluepairs? also, it might have something to do with your serversettings
Update: this is a piece of code I use:
InputStream is = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("lastupdate", lastupdate));
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(connection);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
Log.d("HTTP", "HTTP: OK");
} catch (Exception e) {
Log.e("HTTP", "Error in http connection " + e.toString());
}
This blog explains your problem neatly Async Best Practices.
The gist of it being you shouldn't use void as return for an async method, unless it's an async event handler, this is bad practice because it doesn't allow exceptions to be caught ;-).
Best practice would be to change the return type to Task. Also, try to code async all the way trough, make every async method call and be called from async methods. Except for a Main method in a console, which can't be async (before C# 7.1).
You will run into deadlocks with GUI and ASP.NET applications if you ignore this best practice. The deadlock occurs because these applications runs on a context that allows only one thread and won't relinquish it to the async thread. This means the GUI waits synchronously for a return, while the async method waits for the context: deadlock.
This behaviour won't happen in a console application, because it runs on context with a thread pool. The async method will return on another thread which will be scheduled. This is why a test console app will work, but the same calls will deadlock in other applications...
NOTE: If your target server endpoint is using secure socket layer (SSL) certificate
Change your .config setting from basicHttpBinding
to basicHttpsBinding
I am sure, It will resolve your problem.
This is the code from the accepted answer above, with some changes made regarding the Base64 encoding. The code below compiles.
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.apache.commons.codec.binary.Base64;
public class HttpBasicAuth {
public static void main(String[] args) {
try {
URL url = new URL ("http://ip:port/login");
Base64 b = new Base64();
String encoding = b.encodeAsString(new String("test1:test1").getBytes());
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
connection.setRequestProperty ("Authorization", "Basic " + encoding);
InputStream content = (InputStream)connection.getInputStream();
BufferedReader in =
new BufferedReader (new InputStreamReader (content));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
}
catch(Exception e) {
e.printStackTrace();
}
}
}
HttpParams is deprecated in the new Apache HTTPClient library. Using the code provided by Laz leads to deprecation warnings.
I suggest to use RequestConfig instead on your HttpGet or HttpPost instance:
final RequestConfig params = RequestConfig.custom().setConnectTimeout(3000).setSocketTimeout(3000).build();
httpPost.setConfig(params);
Try setting maxReceivedMessageSize on the server too, e.g. to 4MB:
<binding name="MyService.MyServiceBinding"
maxReceivedMessageSize="4194304">
The main reason the default (65535 I believe) is so low is to reduce the risk of Denial of Service (DoS) attacks. You need to set it bigger than the maximum request size on the server, and the maximum response size on the client. If you're in an Intranet environment, the risk of DoS attacks is probably low, so it's probably safe to use a value much higher than you expect to need.
By the way a couple of tips for troubleshooting problems connecting to WCF services:
Enable tracing on the server as described in this MSDN article.
Use an HTTP debugging tool such as Fiddler on the client to inspect the HTTP traffic.
The answer from this question provided the answer to this question much more simply.
Write is a special statement designed to generate machine-readable files that are later consumed with Input.
Use Print to avoid any fiddling with data.

Maybe you can use WebView, but as you can see in the doc WebView doesn't support javascript and other stuff like widgets by default.
http://developer.android.com/reference/android/webkit/WebView.html
I think that you can enable javascript if you need it.
To access an array member you use $array['KEY'];
To access an object member you use $obj->KEY;
To access an object member inside an array of objects:
$array[0]
// Get the first object in the array
$array[0]->KEY
// then access its key
You may also loop over an array of objects like so:
foreach ($arrayOfObjs as $key => $object) {
echo $object->object_property;
}
Think of an array as a collection of things. It's a bag where you can store your stuff and give them a unique id (key) and access them (or take the stuff out of the bag) using that key. I want to keep things simple here, but this bag can contain other bags too :)
An array contains 'key
' and 'value
' pairs. Providing a key for an array member is optional and in this case it is automatically assigned a numeric key which starts with 0 and keeps on incrementing by 1 for each additional member. We can retrieve a 'value' from the array by it's 'key
'.
So we can define an array in the following ways (with respect to keys):
$colorPallete = ['red', 'blue', 'green'];
The above array will be assigned numeric keys automatically. So the key assigned to red will be 0, for blue 1 and so on.
$colorPallete[0]; // will output 'red'
$colorPallete[1]; // will output 'blue'
$colorPallete[2]; // will output 'green'
$colorPallete = ['love' => 'red', 'trust' => 'blue', 'envy' => 'green']; // we expliicitely define the keys ourself.
$colorPallete['love']; // will output 'red'
$colorPallete['trust']; // will output 'blue'
$colorPallete['envy']; // will output 'green'
After 8 years the situation is changed a bit.
I'm unable to open a new session of Google Chrome without other parameters and allow 'file:' schema.
On macOS I do:
open -n -a "Google Chrome" --args \
--disable-web-security \ # This disable all CORS and other security checks
--user-data-dir=$HOME/fakeChromeDir # This let you to force open a new Google Chrome session
Without this arguments I'm unable to test the XSL stylesheet in local.
Try This code:
public class GenericCompare<T> : IEqualityComparer<T> where T : class
{
private Func<T, object> _expr { get; set; }
public GenericCompare(Func<T, object> expr)
{
this._expr = expr;
}
public bool Equals(T x, T y)
{
var first = _expr.Invoke(x);
var sec = _expr.Invoke(y);
if (first != null && first.Equals(sec))
return true;
else
return false;
}
public int GetHashCode(T obj)
{
return obj.GetHashCode();
}
}
Example of its use would be
collection = collection
.Except(ExistedDataEles, new GenericCompare<DataEle>(x=>x.Id))
.ToList();
One method I can think of is this:
1) Let the UI bind to the service.
2) Expose a method like the one below by the Binder
that registers your Handler
:
public void registerHandler(Handler handler) {
mHandler = handler;
}
3) In the UI thread, call the above method after binding to the service:
mBinder.registerHandler(new Handler());
4) Use the handler in the Service's thread to post your task:
mHandler.post(runnable);

Do not hesitate to put constraints on the database. You'll be sure to have a consistent database, and that's one of the good reasons to use a database. Especially if you have several applications requesting it (or just one application but with a direct mode and a batch mode using different sources).
With MySQL you do not have advanced constraints like you would have in postgreSQL but at least the foreign key constraints are quite advanced.
We'll take an example, a company table with a user table containing people from theses company
CREATE TABLE COMPANY (
company_id INT NOT NULL,
company_name VARCHAR(50),
PRIMARY KEY (company_id)
) ENGINE=INNODB;
CREATE TABLE USER (
user_id INT,
user_name VARCHAR(50),
company_id INT,
INDEX company_id_idx (company_id),
FOREIGN KEY (company_id) REFERENCES COMPANY (company_id) ON...
) ENGINE=INNODB;
Let's look at the ON UPDATE clause:
And now on the ON DELETE side:
usually my default is: ON DELETE RESTRICT ON UPDATE CASCADE. with some ON DELETE CASCADE
for track tables (logs--not all logs--, things like that) and ON DELETE SET NULL
when the master table is a 'simple attribute' for the table containing the foreign key, like a JOB table for the USER table.
Edit
It's been a long time since I wrote that. Now I think I should add one important warning. MySQL has one big documented limitation with cascades. Cascades are not firing triggers. So if you were over confident enough in that engine to use triggers you should avoid cascades constraints.
MySQL triggers activate only for changes made to tables by SQL statements. They do not activate for changes in views, nor by changes to tables made by APIs that do not transmit SQL statements to the MySQL Server
==> See below the last edit, things are moving on this domain
Triggers are not activated by foreign key actions.
And I do not think this will get fixed one day. Foreign key constraints are managed by the InnoDb storage and Triggers are managed by the MySQL SQL engine. Both are separated. Innodb is the only storage with constraint management, maybe they'll add triggers directly in the storage engine one day, maybe not.
But I have my own opinion on which element you should choose between the poor trigger implementation and the very useful foreign keys constraints support. And once you'll get used to database consistency you'll love PostgreSQL.
as stated by @IstiaqueAhmed in the comments, the situation has changed on this subject. So follow the link and check the real up-to-date situation (which may change again in the future).
To return the whole table at once you could change the SELECT to:
SELECT ...
BULK COLLECT INTO T
FROM ...
This is only advisable for results that aren't excessively large, since they all have to be accumulated in memory before being returned; otherwise consider the pipelined function as suggested by Charles, or returning a REF CURSOR.
For multiple plots in a single pdf file you can use PdfPages
In the plotGraph
function you should return the figure and than call savefig
of the figure object.
------ plotting module ------
def plotGraph(X,Y):
fig = plt.figure()
### Plotting arrangements ###
return fig
------ plotting module ------
----- mainModule ----
from matplotlib.backends.backend_pdf import PdfPages
plot1 = plotGraph(tempDLstats, tempDLlabels)

My few cents on the subject. Assuming that kubectl
is working then the closest command that would be equivalent to the docker command that you mentioned in your question, would be something like this.
$ kubectl run ubuntu --image=ubuntu --restart=Never --command sleep infinity
Above command will create a single Pod
in default
namespace and, it will execute sleep
command with infinity
argument -this way you will have a process that runs in foreground keeping container alive.
Afterwords, you can interact with Pod
by running kubectl exec
command.
$ kubectl exec ubuntu -it -- bash
This technique is very useful for creating a Pod resource and ad-hoc debugging.
If you're running Windows then make use of this:
g++ -o program program.cpp
g++
is the name of the compiler and -o
is the option needed for creating a .o file. Program (without .cpp suffix) is the exe
file and program.cpp
is your source file that you want to compile.
g++ -o program program.cpp&program.exe
Use this shortcut to run the .exe
file of the program. This may run in Ubuntu but you may have to use .out
suffix instead of .exe
. Use this handy batch script I made to execute your programs on Windows:
@echo off&&cls
set /p pathName=Enter The Path where the file is located:%=%
cd %pathName%
REM set /p exec=Enter The Name of the executable you want to make:%=%
set /p file=Enter The Name of the file you want to compile:%=%
g++ -o %file% %file%.cpp
%file%.exe
save it as cppExecutor.bat
Also you could use the following commands on Unix (Linux and Mac) OS:
CC program.cc
If you want to use gcc
:
gcc -o program program.cpp
With the shortcut:
gcc -o program program.cpp&program.exe
I had the same problem and reset didn't fix it. Then the resharper support helped me. Solution was very simple! I'm from Russia and usually my default keyboard is Russian. In control panel | language settings | change keyboard - I changed default keyboard to English. Then reapply settings in VS: Resharper|Options|Keyboard&Menus - apply R# scheme. And the problem was fixed :)
Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).
You need to do a deep equals.
From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.
Object.extend(Object, {
deepEquals: function(o1, o2) {
var k1 = Object.keys(o1).sort();
var k2 = Object.keys(o2).sort();
if (k1.length != k2.length) return false;
return k1.zip(k2, function(keyPair) {
if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
} else {
return o1[keyPair[0]] == o2[keyPair[1]];
}
}).all();
}
});
Usage:
var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);
if (Object.deepEquals(anObj, anotherObj))
...
For Java 7+, there is also https://docs.oracle.com/javase/7/docs/api/java/nio/file/DirectoryStream.html
Example taken from the Javadoc:
List<Path> listSourceFiles(Path dir) throws IOException {
List<Path> result = new ArrayList<>();
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir, "*.{c,h,cpp,hpp,java}")) {
for (Path entry: stream) {
result.add(entry);
}
} catch (DirectoryIteratorException ex) {
// I/O error encounted during the iteration, the cause is an IOException
throw ex.getCause();
}
return result;
}
In Swift:
Add this to the controller
override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.setHidesBackButton(true, animated: false)
}
As a general (see Stackblitz here: https://stackblitz.com/edit/angular-gh2rjx):
HTML
<select [(ngModel)]="selectedOption">
<option *ngFor="let o of options">
{{o.name}}
</option>
</select>
<button (click)="print()">Click me</button>
<p>Selected option: {{ selectedOption }}</p>
<p>Button output: {{ printedOption }}</p>
Typescript
export class AppComponent {
selectedOption: string;
printedOption: string;
options = [
{ name: "option1", value: 1 },
{ name: "option2", value: 2 }
]
print() {
this.printedOption = this.selectedOption;
}
}
In your specific case you can use ngModel like this:
<form class="form-inline" (ngSubmit)="HelloCorp()">
<div class="select">
<select [(ngModel)]="corporationObj" class="form-control col-lg-8" #corporation required>
<option *ngFor="let corporation of corporations"></option>
</select>
<button type="submit" class="btn btn-primary manage">Submit</button>
</div>
</form>
HelloCorp() {
console.log("My input: ", corporationObj);
}
s = "BINGO"
print(s.replace("", " ")[1: -1])
Timings below
$ python -m timeit -s's = "BINGO"' 's.replace(""," ")[1:-1]'
1000000 loops, best of 3: 0.584 usec per loop
$ python -m timeit -s's = "BINGO"' '" ".join(s)'
100000 loops, best of 3: 1.54 usec per loop
I like this:
if (wlocation !== undefined)
But if you prefer the second way wouldn't be as you posted. It would be:
if (typeof wlocation !== "undefined")
That worked for me,
Right Click on project -> "Run as Maven Test". This will automatically download the missing plugins and than Right Click on project ->"Update Maven project" it removes the error.
Try the following.
$d = [datetime](Get-ItemProperty -Path $source -Name LastWriteTime).lastwritetime
This is part of the item property weirdness. When you run Get-ItemProperty it does not return the value but instead the property. You have to use one more level of indirection to get to the value.
To answer the question. stringstream
basically allows you to treat a string
object like a stream
, and use all stream
functions and operators on it.
I saw it used mainly for the formatted output/input goodness.
One good example would be c++
implementation of converting number to stream object.
Possible example:
template <class T>
string num2str(const T& num, unsigned int prec = 12) {
string ret;
stringstream ss;
ios_base::fmtflags ff = ss.flags();
ff |= ios_base::floatfield;
ff |= ios_base::fixed;
ss.flags(ff);
ss.precision(prec);
ss << num;
ret = ss.str();
return ret;
};
Maybe it's a bit complicated but it is quite complex. You create stringstream
object ss
, modify its flags, put a number into it with operator<<
, and extract it via str()
. I guess that operator>>
could be used.
Also in this example the string
buffer is hidden and not used explicitly. But it would be too long of a post to write about every possible aspect and use-case.
Note: I probably stole it from someone on SO and refined, but I don't have original author noted.
ECMAScript 6 introduced the let
statement. You can use it in a for
statement.
var ids:string = [];
for(let result of this.results){
ids.push(result.Id);
}
If you want to use it in plain SQL, I would let the store procedure fill a table or temp table with the resulting rows (or go for @Tony Andrews approach).
If you want to use @Thilo's solution, you have to loop the cursor using PL/SQL.
Here an example: (I used a procedure instead of a function, like @Thilo did)
create or replace procedure myprocedure(retval in out sys_refcursor) is
begin
open retval for
select TABLE_NAME from user_tables;
end myprocedure;
declare
myrefcur sys_refcursor;
tablename user_tables.TABLE_NAME%type;
begin
myprocedure(myrefcur);
loop
fetch myrefcur into tablename;
exit when myrefcur%notfound;
dbms_output.put_line(tablename);
end loop;
close myrefcur;
end;
You probably want to do something like this:
result = MsgBox ("Yes or No?", vbYesNo, "Yes No Example")
Select Case result
Case vbYes
MsgBox("You chose Yes")
Case vbNo
MsgBox("You chose No")
End Select
To add an icon:
result = MsgBox ("Yes or No?", vbYesNo + vbQuestion, "Yes No Example")
Other icon options:
vbCritical or vbExclamation
unchecked the "Automatically detect settings" in the Local Area Network Settings (found in "Internet Options" > Connections > LAN Settings.

Update : From Angular v1.5, track by $index
is now the standard syntax instead of using link as it gave me a ng-repeat

} throws the null pointer exception.

Absolute will make your element out of your flow layout, and it will be positioned to the closest relative parent (all parents are static by default). That's how you use absolute and relative together most of the time.
You can also use relative alone, but that is very rare case.
I have made an video to explain this.
This is for all people who need to increase the radius of ScriptIntrinsicBlur
to obtain a harder gaussian blur.
Instead of to put the radius more than 25, you can scale down the image and get the same result. I wrote a class called GaussianBlur
. Below you can see how to use, and the whole class implementation.
Usage:
GaussianBlur gaussian = new GaussianBlur(context);
gaussian.setMaxImageSize(60);
gaussian.setRadius(25); //max
Bitmap output = gaussian.render(<your bitmap>,true);
Drawable d = new BitmapDrawable(getResources(),output);
Class:
public class GaussianBlur {
private final int DEFAULT_RADIUS = 25;
private final float DEFAULT_MAX_IMAGE_SIZE = 400;
private Context context;
private int radius;
private float maxImageSize;
public GaussianBlur(Context context) {
this.context = context;
setRadius(DEFAULT_RADIUS);
setMaxImageSize(DEFAULT_MAX_IMAGE_SIZE);
}
public Bitmap render(Bitmap bitmap, boolean scaleDown) {
RenderScript rs = RenderScript.create(context);
if (scaleDown) {
bitmap = scaleDown(bitmap);
}
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Config.ARGB_8888);
Allocation inAlloc = Allocation.createFromBitmap(rs, bitmap, Allocation.MipmapControl.MIPMAP_NONE, Allocation.USAGE_GRAPHICS_TEXTURE);
Allocation outAlloc = Allocation.createFromBitmap(rs, output);
ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, inAlloc.getElement()); // Element.U8_4(rs));
script.setRadius(getRadius());
script.setInput(inAlloc);
script.forEach(outAlloc);
outAlloc.copyTo(output);
rs.destroy();
return output;
}
public Bitmap scaleDown(Bitmap input) {
float ratio = Math.min((float) getMaxImageSize() / input.getWidth(), (float) getMaxImageSize() / input.getHeight());
int width = Math.round((float) ratio * input.getWidth());
int height = Math.round((float) ratio * input.getHeight());
return Bitmap.createScaledBitmap(input, width, height, true);
}
public int getRadius() {
return radius;
}
public void setRadius(int radius) {
this.radius = radius;
}
public float getMaxImageSize() {
return maxImageSize;
}
public void setMaxImageSize(float maxImageSize) {
this.maxImageSize = maxImageSize;
}
}

findViewById()
of non existing viewLike when you use findViewById(R.id.button)
when button id does not exist in layout XML.
If you wrong cast some class, then you get this error. Like you cast RelativeLayout
to LinearLayout
or EditText
to TextView
.
manifest.xml
If you did not register Activity in manifest.xml
then this error comes.
findViewById()
with declaration at top levelBelow code is incorrect. This will create error. Because you should do findViewById()
after calling setContentView()
. Because an View can be there after it is created.
public class MainActivity extends Activity {
ImageView mainImage = (ImageView) findViewById(R.id.imageViewMain); //incorrect way
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainImage = (ImageView) findViewById(R.id.imageViewMain); //correct way
//...
}
}
abstract
Activity class.When you try to start an Activity which is abstract, you will will get this error. So just remove abstract
keyword before activity class name.
If your activity is written in Kotlin and you have not setup kotlin in your app. then you will get error. You can follow simple steps as written in Android Link or Kotlin Link. You can check this answer too.

sign. Kotlin has string templates, so it's better to use them like:
var fn = "Hello"
var ln = "World"
"$fn $ln"
for concatenation.
You can even use String.plus()
method.
You can just use the column name directly:
df <- data.frame(A=1:10, B=2:11, C=3:12)
fun1 <- function(x, column){
max(x[,column])
}
fun1(df, "B")
fun1(df, c("B","A"))
There's no need to use substitute, eval, etc.
You can even pass the desired function as a parameter:
fun1 <- function(x, column, fn) {
fn(x[,column])
}
fun1(df, "B", max)
Alternatively, using [[
also works for selecting a single column at a time:
df <- data.frame(A=1:10, B=2:11, C=3:12)
fun1 <- function(x, column){
max(x[[column]])
}
fun1(df, "B")
JEP 354: Switch Expressions (Preview) in JDK-13 and JEP 361: Switch Expressions (Standard) in JDK-14 will extend the switch statement so it can be used as an expression.
Now you can:
case L ->
):
The code to the right of a "case L ->" switch label is restricted to be an expression, a block, or (for convenience) a throw statement.
To yield a value from a switch expression, the
break
with value statement is dropped in favor of ayield
statement.
So the demo from the answers (1, 2) might look like this:
public static void main(String[] args) {
switch (args[0]) {
case "Monday", "Tuesday", "Wednesday" -> System.out.println("boring");
case "Thursday" -> System.out.println("getting better");
case "Friday", "Saturday", "Sunday" -> System.out.println("much better");
}
as of 12.03.2019 FusionTables is no more...
Import the Shapefile into Google FusionTables ( http://www.google.com/fusiontables ) using http://www.shpescape.com/ and from there you can use the data in a number of ways, eg. display it using GoogleMaps.
It is a good idea to verify if the device has these packages installed:
mListPackageName.add("com.google.android.launcher.layouts.genymotion");
mListPackageName.add("com.bluestacks");
mListPackageName.add("com.vphone.launcher");
mListPackageName.add("com.bignox.app");
And then simply check against the package manager till it finds one.
private static boolean isEmulByPackage(Context context) {
final PackageManager pm = context.getPackageManager();
for (final String pkgName : mListPackageName) {
return isPackageInstalled(pkgName, pm);
}
return false;
}
private static boolean isPackageInstalled(final String packageName, final PackageManager packageManager) {
try {
packageManager.getPackageInfo(packageName, 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
You could try this: it's a very good tool, very fast and effective.
Another option could be using bootstrap select. On their own words:
A custom select / multiselect for Bootstrap using button dropdown, designed to behave like regular Bootstrap selects.
We actually had these merged together originally, i.e. there was a "filter"-like method that accepted *args
and **kwargs
, where you could pass a SQL expression or keyword arguments (or both). I actually find that a lot more convenient, but people were always confused by it, since they're usually still getting over the difference between column == expression
and keyword = expression
. So we split them up.
There are some problems with your header()
calls, one of which might be causing problems
exit()
after each of the header("Location:
calls otherwise code execution will continue:
so it reads "Location: http://foo"
Location
header, you should form an absolute URL like http://www.mysite.com/some/path.php

Use the Bit
datatype. It has values 1 and 0 when dealing with it in native T-SQL
Spring uses dependency injection to populate the specific value when it finds the @Value annotation. However, instead of handing the value to the instance variable, it's handed to the implicit setter instead. This setter then handles the population of our NAME_STATIC value.
@RestController
//or if you want to declare some specific use of the properties file then use
//@Configuration
//@PropertySource({"classpath:application-${youeEnvironment}.properties"})
public class PropertyController {
@Value("${name}")//not necessary
private String name;//not necessary
private static String NAME_STATIC;
@Value("${name}")
public void setNameStatic(String name){
PropertyController.NAME_STATIC = name;
}
}
Here is the code to a method I call whenever I want an information box to pop up, it hogs the screen until it is accepted:
import javax.swing.JOptionPane;
public class ClassNameHere
{
public static void infoBox(String infoMessage, String titleBar)
{
JOptionPane.showMessageDialog(null, infoMessage, "InfoBox: " + titleBar, JOptionPane.INFORMATION_MESSAGE);
}
}
The first JOptionPane
parameter (null
in this example) is used to align the dialog. null
causes it to center itself on the screen, however any java.awt.Component
can be specified and the dialog will appear in the center of that Component
instead.
I tend to use the titleBar
String to describe where in the code the box is being called from, that way if it gets annoying I can easily track down and delete the code responsible for spamming my screen with infoBoxes.
To use this method call:
ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE");
For a an in depth description of how to use JavaFX dialogs see: JavaFX Dialogs (official) by code.makery. They are much more powerful and flexible than Swing dialogs and capable of far more than just popping up messages.
As above I'll post a small example of how you could use JavaFX dialogs to achieve the same result
import javafx.scene.control.Alert;
import javafx.scene.control.Alert.AlertType;
import javafx.application.Platform;
public class ClassNameHere
{
public static void infoBox(String infoMessage, String titleBar)
{
/* By specifying a null headerMessage String, we cause the dialog to
not have a header */
infoBox(infoMessage, titleBar, null);
}
public static void infoBox(String infoMessage, String titleBar, String headerMessage)
{
Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle(titleBar);
alert.setHeaderText(headerMessage);
alert.setContentText(infoMessage);
alert.showAndWait();
}
}
One thing to keep in mind is that JavaFX is a single threaded GUI toolkit, which means this method should be called directly from the JavaFX application thread. If you have another thread doing work, which needs a dialog then see these SO Q&As: JavaFX2: Can I pause a background Task / Service? and Platform.Runlater and Task Javafx.
To use this method call:
ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE");
or
ClassNameHere.infoBox("YOUR INFORMATION HERE", "TITLE BAR MESSAGE", "HEADER MESSAGE");
Here are some static methods you can use to get the MaxLength, or any other attribute.
using System;
using System.Linq;
using System.Reflection;
using System.ComponentModel.DataAnnotations;
using System.Linq.Expressions;
public static class AttributeHelpers {
public static Int32 GetMaxLength<T>(Expression<Func<T,string>> propertyExpression) {
return GetPropertyAttributeValue<T,string,MaxLengthAttribute,Int32>(propertyExpression,attr => attr.Length);
}
//Optional Extension method
public static Int32 GetMaxLength<T>(this T instance,Expression<Func<T,string>> propertyExpression) {
return GetMaxLength<T>(propertyExpression);
}
//Required generic method to get any property attribute from any class
public static TValue GetPropertyAttributeValue<T, TOut, TAttribute, TValue>(Expression<Func<T,TOut>> propertyExpression,Func<TAttribute,TValue> valueSelector) where TAttribute : Attribute {
var expression = (MemberExpression)propertyExpression.Body;
var propertyInfo = (PropertyInfo)expression.Member;
var attr = propertyInfo.GetCustomAttributes(typeof(TAttribute),true).FirstOrDefault() as TAttribute;
if (attr==null) {
throw new MissingMemberException(typeof(T).Name+"."+propertyInfo.Name,typeof(TAttribute).Name);
}
return valueSelector(attr);
}
}
Using the static method...
var length = AttributeHelpers.GetMaxLength<Player>(x => x.PlayerName);
Or using the optional extension method on an instance...
var player = new Player();
var length = player.GetMaxLength(x => x.PlayerName);
Or using the full static method for any other attribute (StringLength for example)...
var length = AttributeHelpers.GetPropertyAttributeValue<Player,string,StringLengthAttribute,Int32>(prop => prop.PlayerName,attr => attr.MaximumLength);
Inspired by the Mikael Engver's answer.
Built a tiny, confirm-like vanilla js yes / no dialog.
https://www.npmjs.com/package/yesno-dialog
A singleton is a class which only allows one instance of itself to be created - and gives simple, easy access to said instance. The singleton premise is a pattern across software development.
There is a C# implementation "Implementing the Singleton Pattern in C#" covering most of what you need to know - including some good advice regarding thread safety.
To be honest, It's very rare that you need to implement a singleton - in my opinion it should be one of those things you should be aware of, even if it's not used too often.
There is no tool specifically in the 'setup.exe' installer that offers the functionality of apt-get. There is, however, a command-line package installer for Cygwin that can be downloaded separately, but it is not entirely stable and relies on workarounds.

For long long (or __int64) using MSVS, you should use %I64d:
__int64 a;
time_t b;
...
fprintf(outFile,"%I64d,%I64d\n",a,b); //I is capital i
If you instead had a data.frame (df) that had multiple columns and you want to vectorize you can do
as.matrix(df, ncol=1)
You have two way for your question :
1- Use Update Command in your Trigger.
ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
ON [dbo].[SCHEDULE]
AFTER UPDATE
AS BEGIN
SET NOCOUNT ON;
IF UPDATE (QtyToRepair)
BEGIN
UPDATE SCHEDULE
SET modified = GETDATE()
, ModifiedUser = SUSER_NAME()
, ModifiedHost = HOST_NAME()
FROM SCHEDULE S INNER JOIN Inserted I
ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
WHERE S.QtyToRepair <> I.QtyToRepair
END
END
2- Use Join between Inserted table and deleted table
ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
ON [dbo].[SCHEDULE]
AFTER UPDATE
AS BEGIN
SET NOCOUNT ON;
UPDATE SCHEDULE
SET modified = GETDATE()
, ModifiedUser = SUSER_NAME()
, ModifiedHost = HOST_NAME()
FROM SCHEDULE S
INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber
WHERE S.QtyToRepair <> I.QtyToRepair
AND D.QtyToRepair <> I.QtyToRepair
END
When you use update command for table SCHEDULE
and Set QtyToRepair
Column to new value, if new value equal to old value in one or multi row, solution 1 update all updated row in Schedule table but solution 2 update only schedule rows that old value not equal to new value.
There is no Linq ForEach extension. However, the List
class has a ForEach method on it, if you're willing to use the List
directly.
For what it's worth, the standard foreach
syntax will give you the results you want and it's probably easier to read:
foreach (var x in someValues)
{
list.Add(x + 1);
}
If you're adamant you want an Linq style extension. it's trivial to implement this yourself.
public static void ForEach<T>(this IEnumerable<T> @this, Action<T> action)
{
foreach (var x in @this)
action(x);
}
image
has a shape of (64,64,3)
.
Your input placeholder _x
have a shape of (?, 64,64,3)
.
The problem is that you're feeding the placeholder with a value of a different shape.
You have to feed it with a value of (1, 64, 64, 3)
= a batch of 1 image.
Just reshape your image
value to a batch with size one.
image = array(img).reshape(1, 64,64,3)
P.S: the fact that the input placeholder accepts a batch of images, means that you can run predicions for a batch of images in parallel.
You can try to read more than 1 image (N images) and than build a batch of N image, using a tensor with shape (N, 64,64,3)
If you came here from Google, trying to find where your previously created virtualenv installation ended up, and why there is no command to find it, here's the low-down.
The design of virtualenv
has a fundamental flaw of not being able to keep track of it's own created environments. Someone was not quite in their right mind when they created virtualenv
without having a rudimentary way to keep track of already created environments, and certainly not fit for a time and age when most pip requirements require multi-giga-byte installations, which should certainly not go into some obscure .virtualenvs
sub-directory of your ~/home.
IMO, the created virtualenv directory should be created in $CWD
and a file called ~/.virtualenv
(in home) should keep track of the name and path of that creation. Which is a darn good reason to use Conda/Miniconda3 instead, which does seem to keep good track of this.
As answered here, the only way to keep track of this, is to install yet another package called virtualenvwrapper
. If you don't do that, you will have to search for the created directory by yourself. Clearly, if you don't remember the name or the location it was created with/at, you will most likely never find your virtual environment again...
One try to remedy the situation in windows, is by putting the following functions into your powershell profile:
# wrap virtualenv.exe and write last argument (presumably
# your virtualenv name) to the file: $HOME/.virtualenv.
function ven { if( $args.count -eq 0) {Get-Content ~/.virtualenv } else {virtualenv.exe "$args"; Write-Output ("{0} `t{1}" -f $args[-1],$PWD) | Out-File -Append $HOME/.virtualenv }}
# List what's in the file or the directories under ~/.virtualenvs
function lsven { try {Get-Content ~/.virtualenv } catch {Get-ChildItem ~\.virtualenvs -Directory | Select-Object -Property Name } }
WARNING: This will write to ~\.virtualenv

Take a look at JSMPEG project. There is a great idea implemented there — to decode MPEG in the browser using JavaScript. Bytes from encoder (FFMPEG, for example) can be transfered to browser using WebSockets or Flash, for example. If community will catch up, I think, it will be the best HTML5 live video streaming solution for now.
I created a code to jump to the desired back stack index, it worked fine to my purpose.
ie. I have Fragment1, Fragment2 and Fragment3, I want to jump from Fragment3 to Fragment1
I created a method called onBackPressed in Fragment3 that jumps to Fragment1
Fragment3:
public void onBackPressed() {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.popBackStack(fragmentManager.getBackStackEntryAt(fragmentManager.getBackStackEntryCount()-2).getId(), FragmentManager.POP_BACK_STACK_INCLUSIVE);
}
In the activity, I need to know if my current fragment is the Fragment3, so I call the onBackPressed of my fragment instead calling super
FragmentActivity:
@Override
public void onBackPressed() {
Fragment f = getSupportFragmentManager().findFragmentById(R.id.my_fragment_container);
if (f instanceof Fragment3)
{
((Fragment3)f).onBackPressed();
} else {
super.onBackPressed();
}
}
Already tested by me, it works fine
For i =0 To ListBox2.items.count - 1
ListBox2.Items.removeAt(0)

Combining the recommendations from others for specifying a character encoding and buffering the input, here's what I think is a pretty complete answer.
Assuming you have a File
object representing the file you want to read:
BufferedReader reader = new BufferedReader(
new InputStreamReader(
new FileInputStream(file),
Charset.forName("UTF-8")));
int c;
while((c = reader.read()) != -1) {
char character = (char) c;
// Do something with your character
}
In Swift, you can overload existing operators:
func > (lhs: NSDate, rhs: NSDate) -> Bool {
return lhs.timeIntervalSinceReferenceDate > rhs.timeIntervalSinceReferenceDate
}
func < (lhs: NSDate, rhs: NSDate) -> Bool {
return lhs.timeIntervalSinceReferenceDate < rhs.timeIntervalSinceReferenceDate
}
Then, you can compare NSDates directly with <
, >
, and ==
(already supported).
select format(convert(float,@your_column),'0.0#########')
Advantage: This solution is irrespective of the source datatype (float, scientific, varchar, date etc)
String
is limited to 10 digits, bigInt

Set the auto increment field to NULL or 0 if you want it to be auto magically assigned...
Sure, just do
```{r someVar, echo=FALSE}
someVariable
```
to show some (previously computed) variable someVariable
. Or run code that prints etc pp.
So for plotting, I have eg
### Impact of choice of ....
```{r somePlot, echo=FALSE}
plotResults(Res, Grid, "some text", "some more text")
```
where the plotting function plotResults
is from a local package.
For simplicity I will use bytes:
byte a=250;
byte b=8;
byte c=a+b;
if a, b, and c were 'int', you would expect 258, but in the case of 'byte', the expected result would be 2 (258 & 0xFF), but in a Windows application you get an exception, in a console one you may not (I don't, but this may depend on IDE, I use SharpDevelop).
Sometimes, however, that behaviour is desired (e.g. you only care about the lower 8 bits of the result).
You could do the following:
byte a=250;
byte b=8;
byte c=(byte)((int)a + (int)b);
This way both 'a' and 'b' are converted to 'int', added, then casted back to 'byte'.
To be on the safe side, you may also want to try:
...
byte c=(byte)(((int)a + (int)b) & 0xFF);
Or if you really want that behaviour, the much simpler way of doing the above is:
unchecked
{
byte a=250;
byte b=8;
byte c=a+b;
}
Or declare your variables first, then do the math in the 'unchecked' section.
Alternately, if you want to force the checking of overflow, use 'checked' instead.
Hope this clears things up.

P.S.
Trust me, that exception is your friend :)
final keyword in the method input parameter is not needed. Java creates a copy of the reference to the object, so putting final on it doesn't make the object final but just the reference, which doesn't make sense
Simply just check your run time by go to ant build configuration and change the jre against to jdk (if jdk 1.7 then jre should be 1.7) .
Try this:
$('input:radio[name="mygroup"][value="5"]').attr('checked',true);
You can use the fixed
CSS position property to accomplish this. There is a basic tutorial on this here.
EDIT: However, this approach is NOT supported in IE versions < IE7, and only in IE7 if it is in standards mode. This is discussed in a little more detail here.
There is also a hack, explained here, that shows how to accomplish fixed positioning in IE6 without affecting absolute positioning. What version of IE are you targeting your website for?
In Windows machine, please follows the preceding steps.
Now source your db.
Each of the three conditions is evaluated independently[1]:
id != 1 // false
id != 2 // true
id != 3 // true
Then it evaluates false || true || true
, which is true (a || b
is true if either a
or b
is true). I think you want
id != 1 && id != 2 && id != 3
which is only true if the ID is not 1 AND it's not 2 AND it's not 3.
[1]: This is not strictly true, look up short-circuit evaluation. In reality, only the first two clauses are evaluated because that is all that is necessary to determine the truth value of the expression.
Very simple steps:
You will see disable button over the extension, click to it then restart Visual Studio and that's it!
The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.
See also here: How to supply value to an annotation from a Constant java
It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.
jQuery takes care of this for you. The first argument to your .each()
callback function is the index of the current iteration of the loop. The second being the current matched DOM element So:
$('#list option').each(function(index, element){
alert("Iteration: " + index)
});
I assume you're using GCC. The standard solution would be to profile with gprof.
Be sure to add -pg
to compilation before profiling:
cc -o myprog myprog.c utils.c -g -pg
I haven't tried it yet but I've heard good things about google-perftools. It is definitely worth a try.
Related question here.
A few other buzzwords if gprof
does not do the job for you: Valgrind, Intel VTune, Sun DTrace.
I guess this is essentially putting it in a string, but this avoids the rounding error:
import decimal
def display(x):
digits = 15
temp = str(decimal.Decimal(str(x) + '0' * digits))
return temp[:temp.find('.') + digits + 1]
A simple recursive C++ implementation would look like this:
#include <iostream>
void generatePermutations(std::string &sequence, int index){
if(index == sequence.size()){
std::cout << sequence << "\n";
} else{
generatePermutations(sequence, index + 1);
for(int i = index + 1 ; i < sequence.size() ; ++i){
std::swap(sequence[index], sequence[i]);
generatePermutations(sequence, index + 1);
std::swap(sequence[index], sequence[i]);
}
}
}
int main(int argc, char const *argv[])
{
std::string str = "abc";
generatePermutations(str, 0);
return 0;
}
Output:
abc
acb
bac
bca
cba
cab
UPDATE
If you want to store the results, you can pass a vector
as the third argument to the function call. Furthermore, if you only want the unique permutations, you can use a set
.
#include <iostream>
#include <vector>
#include <set>
void generatePermutations(std::string &sequence, int index, std::vector <std::string> &v){
if(index == sequence.size()){
//std::cout << sequence << "\n";
v.push_back(sequence);
} else{
generatePermutations(sequence, index + 1, v);
for(int i = index + 1 ; i < sequence.size() ; ++i){
std::swap(sequence[index], sequence[i]);
generatePermutations(sequence, index + 1, v);
std::swap(sequence[index], sequence[i]);
}
}
}
int main(int argc, char const *argv[])
{
std::string str = "112";
std::vector <std::string> permutations;
generatePermutations(str, 0, permutations);
std::cout << "Number of permutations " << permutations.size() << "\n";
for(const std::string &s : permutations){
std::cout << s << "\n";
}
std::set <std::string> uniquePermutations(permutations.begin(), permutations.end());
std::cout << "Number of unique permutations " << uniquePermutations.size() << "\n";
for(const std::string &s : uniquePermutations){
std::cout << s << "\n";
}
return 0;
}
Output:
Number of permutations 6
112
121
112
121
211
211
Number of unique permutations 3
112
121
211
Try moving the order by
after group by
:
var groupByReference = (from m in context.Measurements
group m by new { m.Reference } into g
order by g.Avg(i => i.CreationTime)
select g).Take(numOfEntries).ToList();
Just use the Cells function and loop thru columns. Cells(Row,Column)
In my case even after following all of the above. I had to upgrade my project from .net 3.5 to .net 4 to authorize against our internal exchange 2010 mail server.
You could include .PDB
symbol files associated to the assembly which contain metadata information and when an exception is thrown it will contain full information in the stacktrace of where this exception originated. It will contain line numbers of each method in the stack.

i solved same problem like this:
I would say that the specification does not prevent someone from creating an engine that runs javascript on multiple threads, requiring the code to perform synchronization for accessing shared object state.
I think the single-threaded non-blocking paradigm came out of the need to run javascript in browsers where ui should never block.
Nodejs has followed the browsers' approach.
Rhino engine however, supports running js code in different threads. The executions cannot share context, but they can share scope. For this specific case the documentation states:
..."Rhino guarantees that accesses to properties of JavaScript objects are atomic across threads, but doesn't make any more guarantees for scripts executing in the same scope at the same time.If two scripts use the same scope simultaneously, the scripts are responsible for coordinating any accesses to shared variables."
From reading Rhino documentation I conclude that that it can be possible for someone to write a javascript api that also spawns new javascript threads, but the api would be rhino-specific (e.g. node can only spawn a new process).
I imagine that even for an engine that supports multiple threads in javascript there should be compatibility with scripts that do not consider multi-threading or blocking.
Concearning browsers and nodejs the way I see it is:
So, in case of browsers and nodejs (and probably a lot of other engines) javascript is not multithreaded but the engines themselves are.
The presence of web-workers justifies further that javascript can be multi-threaded, in the sense that someone can create code in javascript that will run on a separate thread.
However: web-workers do not curry the problems of traditional threads who can share execution context. Rules 2 and 3 above still apply, but this time the threaded code is created by the user (js code writer) in javascript.
The only thing to consider is the number of spawned threads, from an efficiency (and not concurrency) point of view. See below:
The Worker interface spawns real OS-level threads, and mindful programmers may be concerned that concurrency can cause “interesting” effects in your code if you aren't careful.
However, since web workers have carefully controlled communication points with other threads, it's actually very hard to cause concurrency problems. There's no access to non-threadsafe components or the DOM. And you have to pass specific data in and out of a thread through serialized objects. So you have to work really hard to cause problems in your code.
Besides theory, always be prepared about possible corner cases and bugs described on the accepted answer
This one looks better than the others I think.
USE [enter your db name here]

A.Name, AVG(B.rows) AS 'RowCount'

The iframe element.
<iframe src="name.html"></iframe>
But content that you way to have appear on multiple pages is better handled using templates.
Autofill works with name attribute of the input, so if you set a name for an input like "firstname", chrome will fill it.
If you want to disable it, use an odd name like "supermanname".
Javascript can't solve your problem.
Second solution: You can make your inputs hidden with the same names, and set their values with other inputs. I simplified the Js with jQUery.
<form action="handlerfile.php" method="post">
<input type="text" id="1" onclick="$("#2").val($("#1").val())"/>
<input type="hidden" name="username" id="2">
</form>
OP here (I am answering this question after two years, the post made by Daniel Cerecedo was not bad at a time, but the web services are developing very fast)
After three years of full-time software development (with focus also on software architecture, project management and microservice architecture) I definitely choose the second way (but with one general endpoint) as the best one.
If you have a special endpoint for images, it gives you much more power over handling those images.
We have the same REST API (Node.js) for both - mobile apps (iOS/android) and frontend (using React). This is 2017, therefore you don't want to store images locally, you want to upload them to some cloud storage (Google cloud, s3, cloudinary, ...), therefore you want some general handling over them.
Our typical flow is, that as soon as you select an image, it starts uploading on background (usually POST on /images endpoint), returning you the ID after uploading. This is really user-friendly, because user choose an image and then typically proceed with some other fields (i.e. address, name, ...), therefore when he hits "send" button, the image is usually already uploaded. He does not wait and watching the screen saying "uploading...".
The same goes for getting images. Especially thanks to mobile phones and limited mobile data, you don't want to send original images, you want to send resized images, so they do not take that much bandwidth (and to make your mobile apps faster, you often don't want to resize it at all, you want the image that fits perfectly into your view). For this reason, good apps are using something like cloudinary (or we do have our own image server for resizing).
Also, if the data are not private, then you send back to app/frontend just URL and it downloads it from cloud storage directly, which is huge saving of bandwidth and processing time for your server. In our bigger apps there are a lot of terabytes downloaded every month, you don't want to handle that directly on each of your REST API server, which is focused on CRUD operation. You want to handle that at one place (our Imageserver, which have caching etc.) or let cloud services handle all of it.
Cons : The only "cons" which you should think of is "not assigned images". User select images and continue with filling other fields, but then he says "nah" and turn off the app or tab, but meanwhile you successfully uploaded the image. This means you have uploaded an image which is not assigned anywhere.
There are several ways of handling this. The most easiest one is "I don't care", which is a relevant one, if this is not happening very often or you even have desire to store every image user send you (for any reason) and you don't want any deletion.
Another one is easy too - you have CRON and i.e. every week and you delete all unassigned images older than one week.
actually I found a novel solution that really helped me out, If you are especially concerned with the index of a certain value in a list or data set, you can just set the value of dictionary to that Index!:
Just watch:
list = ['a', 'b', 'c']
dictionary = {}
counter = 0
for i in list:
dictionary[i] = counter
counter += 1
print(dictionary) # dictionary = {'a':0, 'b':1, 'c':2}
Now through the power of hashmaps you can pull the index your entries in constant time (aka a whole lot faster)
cout << fixed << setprecision(2) << total;
setprecision
specifies the minimum precision. So
cout << setprecision (2) << 1.2;
will print 1.2
fixed
says that there will be a fixed number of decimal digits after the decimal point
cout << setprecision (2) << fixed << 1.2;
will print 1.20
I used aggregate function to force paths combine as below:
public class MyPath
{
public static string ForceCombine(params string[] paths)
{
return paths.Aggregate((x, y) => Path.Combine(x, y.TrimStart('\\')));
}
}
In SQL
you can not have a variable array.
However, the best alternative solution is to use a temporary table.
While there are a lot of answers which focuses on solving the issue at hand but don't talk much about the various trade-off which someone needs to make before choosing a particular answer. So let me try to add a few more details on this perspective.
Partial search is now a day a very common and important feature and if not implemented properly can lead to poor user experience and bad performance, so first know your application function and non-function requirement related to this feature which I talked about in my this detailed SO answer.
Now there are various approaches, like query time, index time, completion suggester and search as you type data-types added in recent version of elasticsarch.
Now people who quickly want to just implement a solution can use below end to end working solution.

Quick review,
From x86 assembly tutorial,
The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.
Your num is 1 byte. Try declaring it with DD
so that it becomes 4 bytes and matches with pop
semantics.
This can be due to system cannot find firefox installed location on path.
Try following code, which should work.
System.setProperty("webdriver.firefox.bin","C:\\Program Files\\Mozilla Firefox\\firefox.exe");
System.setProperty("webdriver.gecko.driver","<location of geckodriver>\\geckodriver.exe");
You do realize that format has nothing to do with how SQL Server stores datetime, right?
You can use set dateformat
for each session. There is no setting for database only.
If you use parameters for data insert or update or where filtering you won't have any problems with that.
Based on Jayarjo's answer:
var loopDate = new Date();
loopDate.setTime(datFrom.valueOf());
while (loopDate.valueOf() < datTo.valueOf() + 86400000) {
alert(loopDay);
loopDate.setTime(loopDate.valueOf() + 86400000);
}
Have you tried ALTER SYSTEM KILL SESSION? Get the SID and SERIAL# from V$SESSION for each session in the given schema, then do
ALTER SCHEMA KILL SESSION sid,serial#;
Heres a quick solution.
You find styles.xml and you change the base application theme to "Theme.AppCompat.NoActionBar" as shown below.
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<!-- Customize your theme here. -->
</style>
You could also check out paramiko. There's no scp module (yet), but it fully supports sftp.
[EDIT] Sorry, missed the line where you mentioned paramiko. The following module is simply an implementation of the scp protocol for paramiko. If you don't want to use paramiko or conch (the only ssh implementations I know of for python), you could rework this to run over a regular ssh session using pipes.
To change the connect mode selection try Settings -> Wireless & Networks -> USB Connection. You can shoose to Charging, Mass Storage, Tethered, and ask on connection.
For a SOAP 1.2 Webservice, I normally use
curl --header "content-type: application/soap+xml" --data @filetopost.xml http://domain/path
I solved it by making use of Type Assertions before exporting the component. TypeScript wasn't able to identify after composing it using redux 'compose' therefore I divided props types into IParentProps and IProps and use IParentProps while doing Type Assertions
import { compose } from 'react-redux'
import HOC1 from 'HOCs/HOC1'
import HOC2 from 'HOCs/HOC2'
type IParentProps = {}
type IProps = {}
const Component: React.FC<IProps & IParentProps> = React.memo((props) => {
return <SomeComponent {...props}/>
})
return compose(HOC1,HOC2)(Component) as React.FunctionComponent<IParentProps>
You need to create a service to be able to share data between controllers.
app.factory('myService', function() {
var savedData = {}
function set(data) {
savedData = data;
}
function get() {
return savedData;
}
return {
set: set,
get: get
}
});
In your controller A:
myService.set(yourSharedData);
In your controller B:
$scope.desiredLocation = myService.get();
Remember to inject myService in the controllers by passing it as a parameter.
Another option is the lubridate
package:
library(lubridate)
x <- 15103
as_date(x, origin = lubridate::origin)
"2011-05-09"
y <- 1442866615
as_datetime(y, origin = lubridate::origin)
"2015-09-21 20:16:55 UTC"
From the docs:
Origin is the date-time for 1970-01-01 UTC in POSIXct format. This date-time is the origin for the numbering system used by POSIXct, POSIXlt, chron, and Date classes.
A good reason is for security - this can prevent CSRF attacks because this header cannot be added to the AJAX request cross domain without the consent of the server via CORS.
Only the following headers are allowed cross domain:
- Accept
- Accept-Language
- Content-Language
- Last-Event-ID
- Content-Type
any others cause a "pre-flight" request to be issued in CORS supported browsers.
Without CORS it is not possible to add X-Requested-With
to a cross domain XHR request.
If the server is checking that this header is present, it knows that the request didn't initiate from an attacker's domain attempting to make a request on behalf of the user with JavaScript. This also checks that the request wasn't POSTed from a regular HTML form, of which it is harder to verify it is not cross domain without the use of tokens. (However, checking the Origin
header could be an option in supported browsers, although you will leave old browsers vulnerable.)
You may wish to combine this with a token, because Flash running on Safari on OSX can set this header if there's a redirect step. It appears it also worked on Chrome, but is now remediated. More details here including different versions affected.
OWASP Recommend combining this with an Origin and Referer check:
This defense technique is specifically discussed in section 4.3 of Robust Defenses for Cross-Site Request Forgery. However, bypasses of this defense using Flash were documented as early as 2008 and again as recently as 2015 by Mathias Karlsson to exploit a CSRF flaw in Vimeo. But, we believe that the Flash attack can't spoof the Origin or Referer headers so by checking both of them we believe this combination of checks should prevent Flash bypass CSRF attacks. (NOTE: If anyone can confirm or refute this belief, please let us know so we can update this article)
However, for the reasons already discussed checking Origin can be tricky.
Written a more in depth blog post on CORS, CSRF and X-Requested-With here.
On Linux, and Unix in general, "r"
and "rb"
are the same. More specifically, a FILE
pointer obtained by fopen()
ing a file in in text mode and in binary mode behaves the same way on Unixes. On windows, and in general, on systems that use more than one character to represent "newlines", a file opened in text mode behaves as if all those characters are just one character, '\n'
.
If you want to portably read/write text files on any system, use "r"
, and "w"
in fopen()
. That will guarantee that the files are written and read properly. If you are opening a binary file, use "rb"
and "wb"
, so that an unfortunate newline-translation doesn't mess your data.
Note that a consequence of the underlying system doing the newline translation for you is that you can't determine the number of bytes you can read from a file using fseek(file, 0, SEEK_END).
Finally, see What's the difference between text and binary I/O? on comp.lang.c FAQs.
This gets a view controller from the storyboard and presents it.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let secondViewController = storyboard.instantiateViewController(withIdentifier: "secondViewControllerId") as! SecondViewController
self.present(secondViewController, animated: true, completion: nil)
Change the storyboard name, view controller name, and view controller id as appropriate.
If you use <img> tags, then webkit based browsers won't display embedded bitmapped images.
For any kind of advanced SVG use, including the SVG inline offers by far the most flexibility.
Internet Explorer and Edge will resize the SVG correctly, but you must specify both the height and width.
You can add onclick, onmouseover, etc. inside the svg, to any shape in the SVG: onmouseover="top.myfunction(evt);"
You can also use web fonts in the SVG by including them in your regular style sheet.
Note: if you are exporting SVG's from Illustrator, the web font names will be wrong. You can correct this in your CSS and avoid messing around in the SVG. For example, Illustrator gives the wrong name to Arial, and you can fix it like this:
@font-face {
font-family: 'ArialMT';
src:
local('Arial'),
local('Arial MT'),
local('Arial Regular');
font-weight: normal;
font-style: normal;
}
All this works on any browser released since 2013.
For an example, see ozake.com. The whole site is made of SVG's except for the contact form.
Warning: Web fonts are imprecisely resized in Safari — and if you have lots of transitions from plain text to bold or italic, there may be a small amount of extra or missing space at the transition points. See my answer at this question for more information.
Transparency can be coded in the color argument as well. It is just two more hex numbers coding a transparency between 0 (fully transparent) and 255 (fully visible). I once wrote this function to add transparency to a color vector, maybe it is usefull here?
addTrans <- function(color,trans)
{
# This function adds transparancy to a color.
# Define transparancy with an integer between 0 and 255
# 0 being fully transparant and 255 being fully visable
# Works with either color and trans a vector of equal length,
# or one of the two of length 1.
if (length(color)!=length(trans)&!any(c(length(color),length(trans))==1)) stop("Vector lengths not correct")
if (length(color)==1 & length(trans)>1) color <- rep(color,length(trans))
if (length(trans)==1 & length(color)>1) trans <- rep(trans,length(color))
num2hex <- function(x)
{
hex <- unlist(strsplit("0123456789ABCDEF",split=""))
return(paste(hex[(x-x%%16)/16+1],hex[x%%16+1],sep=""))
}
rgb <- rbind(col2rgb(color),trans)
res <- paste("#",apply(apply(rgb,2,num2hex),2,paste,collapse=""),sep="")
return(res)
}
Some examples:
cols <- sample(c("red","green","pink"),100,TRUE)
# Fully visable:
plot(rnorm(100),rnorm(100),col=cols,pch=16,cex=4)
# Somewhat transparant:
plot(rnorm(100),rnorm(100),col=addTrans(cols,200),pch=16,cex=4)
# Very transparant:
plot(rnorm(100),rnorm(100),col=addTrans(cols,100),pch=16,cex=4)
If you're using Cordova 3.3 or higher and your device is running Android 4.4 or higher you can use 'Remote Debugging on Android with Chrome'. Full instructions are here:

Here's a simple little function that will rbind two datasets together after auto-detecting what columns are missing from each and adding them with all NA
s.
For whatever reason this returns MUCH faster on larger datasets than using the merge
function.
fastmerge <- function(d1, d2) {
d1.names <- names(d1)
d2.names <- names(d2)
# columns in d1 but not in d2
d2.add <- setdiff(d1.names, d2.names)
# columns in d2 but not in d1
d1.add <- setdiff(d2.names, d1.names)
# add blank columns to d2
if(length(d2.add) > 0) {
for(i in 1:length(d2.add)) {
d2[d2.add[i]] <- NA
}
}
# add blank columns to d1
if(length(d1.add) > 0) {
for(i in 1:length(d1.add)) {
d1[d1.add[i]] <- NA
}
}
return(rbind(d1, d2))
}

Using docker compose you can mount a volume with postgresql.auto.conf
.
Example:
version: '2'
services:
db:
image: postgres:10.9-alpine
volumes:
- postgres:/var/lib/postgresql/data:z
- ./docker/postgres/postgresql.auto.conf:/var/lib/postgresql/data/postgresql.auto.conf
ports:
- 5432:5432
None of the above worked for me, the only one working was
insert into tableName
select 11, 'BALOO' from sysibm.sysdummy1 union all
select 22, nullif('','') AS nullColumn from sysibm.sysdummy1
The nullif is used since it is not possible to pass null in the select statement otherwise.
I did it this way (you need to add a class text to <td>
and put the text between a <span>
:
HTML
<td class="text"><span>looooooong teeeeeeeeext</span></td>
SASS
.table td.text {
max-width: 177px;
span {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
display: inline-block;
max-width: 100%;
}
}
CSS equivalent
.table td.text {
max-width: 177px;
}
.table td.text span {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
display: inline-block;
max-width: 100%;
}
And it will still be mobile responsive (forget it with layout=fixed) and will keep the original behaviour.
PS: Of course 177px is a custom size (put whatever you need).
This works for me. Try this one before the start of HTML. I hope it will also work for you.
<?php header('Content-Type: text/html; charset=iso-8859-15'); ?>_x000D_
<!DOCTYPE html>_x000D_
_x000D_
<html lang="en-US">_x000D_
<head>
_x000D_
You can do it in-place like so:
l = [1, 2, 3, 4, 5]
l[:] = [x * 5 for x in l]
This requires no additional imports and is very pythonic.

You need to merge the remote branch into your current branch by running git pull
.
If your local branch is already up-to-date, you may also need to run git pull --rebase
.
A quick google search also turned up this same question asked by another SO user: Cannot push to GitHub - keeps saying need merge. More details there.
You may also change inheritance from ActionBarActivity to Activity as written here.
UPDATE
A good solution is here:
@Override

getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
setContentView(R.layout.activity_main);
}
Asterisk (*
) works with alias. Ex:
from pyspark.sql.functions import *
df1 = df1.alias('df1')
df2 = df2.alias('df2')
df1.join(df2, df1.id == df2.id).select('df1.*')
The only way I have 100% consistently been able to avoid this flex-direction column bug is to use a min-width media query to assign a max-width to the child element on desktop sized screens.
.parent {
display: flex;
flex-direction: column;
}
//a media query targeting desktop sort of sized screens
@media screen and (min-width: 980px) {
.child {
display: block;
max-width: 500px;//maximimum width of the element on a desktop sized screen
}
}
You will need to set naturally inline child elements (eg. <span>
or <a>
) to something other than inline (mainly display:block or display:inline-block) for the fix to work.
You can also use np.size(a,1), 1 here is the axis and this will give you the number of columns
This solution doesn't require an import:
tuple(map(lambda x, y: x + y, tuple1, tuple2))
In Swift3:
let fileUrl = Foundation.URL(string: filePath)
Below is the solution that worked for me. This function is in a controller and will return a structured array of all the error messages and the field that caused them.
Symfony 2.0:
private function getErrorMessages(\Symfony\Component\Form\Form $form) {
$errors = array();
foreach ($form->getErrors() as $key => $error) {
$template = $error->getMessageTemplate();
$parameters = $error->getMessageParameters();
foreach($parameters as $var => $value){
$template = str_replace($var, $value, $template);
}
$errors[$key] = $template;
}
if ($form->hasChildren()) {
foreach ($form->getChildren() as $child) {
if (!$child->isValid()) {
$errors[$child->getName()] = $this->getErrorMessages($child);
}
}
}
return $errors;
}
Symfony 2.1 and newer:
private function getErrorMessages(\Symfony\Component\Form\Form $form) {
$errors = array();
if ($form->hasChildren()) {
foreach ($form->getChildren() as $child) {
if (!$child->isValid()) {
$errors[$child->getName()] = $this->getErrorMessages($child);
}
}
} else {
foreach ($form->getErrors() as $key => $error) {
$errors[] = $error->getMessage();
}
}
return $errors;
}
this things is worked on laravel 5.1.
first, on your terminal execute this code
php artisan make:migration add_paid_to_users --table=users
after that go to your project directory and expand directory database - migration and edit file add_paid_to_users.php, add this code
public function up()
{
Schema::table('users', function (Blueprint $table) {
$table->string('paid'); //just add this line
});
}
after that go back to your terminal and execute this command
php artisan migrate
hope this help.

This will likely cause no trouble at all. But if you want to be really on the save side, you should install the correct, old JDK. You can find them here: http://www.oracle.com/technetwork/java/archive-139210.html
If you then restart eclipse you can go into Window > Preferences > Java > Installed JREs > Execution Environments and set for in your case J2SE-1.4 the [perfect match] as eclipse calls it.
Use "in" or "where".
Its gonna be something like this:
db.mycollection.find( { $where : function() {
return ( this.startTime < Now() && this.expireTime > Now() || this.expireTime == null ); } } );
If you have PHP >= 5.1:
function isWeekend($date) {
return (date('N', strtotime($date)) >= 6);
}
otherwise:
function isWeekend($date) {
$weekDay = date('w', strtotime($date));
return ($weekDay == 0 || $weekDay == 6);
}
I found this from: accounting.js . Its very easy and perfectly fits my need.
// Default usage:_x000D_
accounting.formatMoney(12345678); // $12,345,678.00_x000D_

I created custom styles by just overriding jQuery classes in inline style. So on top of the page, you have the jQuery CSS linked and right after that override the classes you need to modify:
<head>
<link href="/Content/theme/base/jquery.ui.all.css" rel="stylesheet"/>
<style type="text/css">
.ui-dialog .ui-dialog-content
{
position: relative;
border: 0;
padding: .5em 1em;
background: none;
overflow: auto;
zoom: 1;
background-color: #ffd;
border: solid 1px #ea7;
}
.ui-dialog .ui-dialog-titlebar
{
display:none;
}
.ui-widget-content
{
border:none;
}
</style>
</head>
To get the list of multiple records use following command
select field1,field2,field3, count(*)
from table_name
group by field1,field2,field3
having count(*) > 1
import moduleName
for x in dir(moduleName):
print(x)
This should work :)
You could come across another problem. After installing Boost on the Linux Mint I've had the same problem. Linking -lboost_system
or -lboost_system-mt
haven't worked because library have had name libboost_system.so.1.54.0
.
So the solution is to create symbolic link to the original file. In my case
sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_system.so.1.54.0 /usr/lib/libboost_system.so
For more information see this question.
It was suggested to post this as an answer, because some other answers are giving errors like 'The name Context does not exist in the current context'.
Just using the following works:
Request.Query["queryparm1"]
Sample usage:
<a href="@Url.Action("Query",new {parm1=Request.Query["queryparm1"]})">GO</a>
This is a charset issue. As such, it can have gone wrong on many different levels, but most likely, the strings in your database are utf-8 encoded, and you are presenting them as iso-8859-1. Or the other way around.
The proper way to fix this problem, is to get your character-sets straight. The simplest strategy, since you're using PHP, is to use iso-8859-1 throughout your application. To do this, you must ensure that:
charset=iso-8859-1
header
.accept-charset
attribute on your <form>
elements.If you already have data in your database, you should be aware that they are probably messed up already. If you are not already in production phase, just wipe it all and start over. Otherwise you'll have to do some data cleanup.
When a web-server serves a file (A HTML-document), it sends some information, that isn't presented directly in the browser. This is known as HTTP-headers. One such header, is the Content-Type
header, which specifies the mimetype of the file (Eg. text/html
) as well as the encoding (aka charset).
While most webservers will send a Content-Type
header with charset
info, it's optional. If it isn't present, the browser will instead interpret any meta-tags with http-equiv="Content-Type"
. It's important to realise that the meta-tag is only interpreted if the webserver doesn't send the header. In practice this means that it's only used if the page is saved to disk and then opened from there.
This page has a very good explanation of these things.
This works for PL/SQL:
select count(*), id,address from table group by id,address having count(*)<2
Use java.util.concurrent.TimeUnit
:
TimeUnit.SECONDS.sleep(1);
Sleep for one second or
TimeUnit.MINUTES.sleep(1);
Sleep for a minute.
As this is a loop, this presents an inherent problem - drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second. If this is an issue then don't use sleep
.
Further, sleep
isn't very flexible when it comes to control.
For running a task every second or at a one second delay I would strongly recommend a [ScheduledExecutorService
][1] and either [scheduleAtFixedRate
][2] or [scheduleWithFixedDelay
][3].
To run the method myTask
every second (Java 8):
public static void main(String[] args) {
final ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
executorService.scheduleAtFixedRate(App::myTask, 0, 1, TimeUnit.SECONDS);
}
private static void myTask() {
System.out.println("Running");
}
Apart from what it's written in other answers, other details related to path of cookie, maximum age of cookie, whether it's secured or not also passed in Set-Cookie response header. For instance:
Set-Cookie:
name=
value[; expires=
date][; domain=
domain][; path=
path][; secure
]
However, not all of these details are passed back to the server by the client when making next HTTP request.
You can also set HttpOnly
flag at the end of your cookie, to indicate that your cookie is httponly and must not allowed to be accessed, in scripts by javascript code. This helps to prevent attacks such as session-hijacking.
For more information, see RFC 2109. Also have a look at Nicholas C. Zakas's article, HTTP cookies explained.
From your comment:
this line
DateTime Date = reader.GetDateTime(0);
was throwing the exception
The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:
SELECT * from INFO
Replace it with a query that retrieves only the two columns you're interested in:
SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO
Then try reading the values again:
var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1); // equivalent to time(7) from your database
Or:
var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];
Use to_datetime
, there is no need for a format string the parser is man/woman enough to handle it:
In [51]:
pd.to_datetime(df['I_DATE'])
Out[51]:
0 2012-03-28 14:15:00
1 2012-03-28 14:17:28
2 2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]
To access the date/day/time component use the dt
accessor:
In [54]:
df['I_DATE'].dt.date
Out[54]:
0 2012-03-28
1 2012-03-28
2 2012-03-28
dtype: object
In [56]:
df['I_DATE'].dt.time
Out[56]:
0 14:15:00
1 14:17:28
2 14:50:50
dtype: object
You can use strings to filter as an example:
In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]
Out[59]:

35 2015-02-05

To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True
Use an extension method:
public static class CommunicationObjectExtensions
{
public static TResult MakeSafeServiceCall<TResult, TService>(this TService client, Func<TService, TResult> method) where TService : ICommunicationObject
{
TResult result;
try
{
result = method(client);
}
finally
{
try
{
client.Close();
}
catch (CommunicationException)
{
client.Abort(); // Don't care about these exceptions. The call has completed anyway.
}
catch (TimeoutException)
{
client.Abort(); // Don't care about these exceptions. The call has completed anyway.
}
catch (Exception)
{
client.Abort();
throw;
}
}
return result;
}
}
If you need a cross-platform solution, try Boost's Program Options library.
Java 8 offers a streams-based alternative to manual iteration:
int[] intArray = Arrays.stream(input.split(","))
.mapToInt(Integer::parseInt)
.toArray();
Be prepared to catch NumberFormatException
if it's possible for the input to contain character sequences that cannot be converted to an integer.
Hope not to be late. It is accomplished using only one line!

Static storage duration means that the variable resides in the same place in memory through the lifetime of the program.
Linkage is orthogonal to this.
I think this is the most important distinction you can make. Understand this and the rest, as well as remembering it, should come easy (not addressing @Tony directly, but whoever might read this in the future).
The keyword static
can be used to denote internal linkage and static storage, but in essence these are different.
What does it mean with local variable? Is that a function local variable?
Yes. Regardless of when the variable is initialized (on first call to the function and when execution path reaches the declaration point), it will reside in the same place in memory for the life of the program. In this case, static
gives it static storage.
Now what about the case with static and file scope? Are all global variables considered to have static storage duration by default?
Yes, all globals have by definition static storage duration (now that we cleared up what that means). But namespace scoped variables aren't declared with static
, because that would give them internal linkage, so a variable per translation unit.
How does static relate to the linkage of a variable?
It gives namespace-scoped variables internal linkage. It gives members and local variables static storage duration.
Let's expand on all this:
//
static int x; //internal linkage
//non-static storage - each translation unit will have its own copy of x
//NOT A TRUE GLOBAL!
int y; //static storage duration (can be used with extern)
//actual global
//external linkage
struct X
{
static int x; //static storage duration - shared between class instances
};
void foo()
{
static int x; //static storage duration - shared between calls
}
This whole static keyword is downright confusing
Definitely, unless you're familiar with it. :) Trying to avoid adding new keywords to the language, the committee re-used this one, IMO, to this effect - confusion. It's used to signify different things (might I say, probably opposing things).
In my case below command worked for windows. It will install latest required version between 3.1.1 and 3.2.0. Depending on OS use either double or single quotes
npm install typescript@">=3.1.1 <3.2.0"
To replace a string in multiple files you can use:
grep -rl string1 somedir/ | xargs sed -i 's/string1/string2/g'
E.g.
grep -rl 'windows' ./ | xargs sed -i 's/windows/linux/g'
You can make extension to just change one color component
static class ColorExtension
{
public static Color ChangeG(Color this color,byte g)
{
return Color.FromArgb(color.A,color.R,g,color.B);
}
}
then you can use this:
yourColor = yourColor.ChangeG(100);
Java API specifies two methods you could use: indexOf(Object obj)
and lastIndexOf(Object obj)
. The first one returns the index of the element if found, -1 otherwise. The second one returns the last index, that would be like searching the list backwards.
Use this: this.$options._scopeId
- is the same identifier used in 'style scoped' section:
All the other solutions are creepy because they are from someone that arrogantly simply thinks that English is the only language in the world :)
All those solutions strip also diacritics like ç or à.
The perfect solution, as stated in PHP documentation, is simply:
$clear = strip_tags($des);
Even after adding @Autowire if your class is not a RestController or Configuration Class, the applicationContext object was coming as null. Tried Creating new class with below and it is working fine:
@Component
public class SpringContext implements ApplicationContextAware{
private static ApplicationContext applicationContext;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws
BeansException {
this.applicationContext=applicationContext;
}
}
you can then implement a getter method in the same class as per your need to get the bean. Like:
applicationContext.getBean(String serviceName,Interface.Class)
On a fresh Linux machine you also need to install git
. Bundle uses it behind the scenes.
You could do something like this also:
ol {
font-weight: bold;
}
ol > li > * {
font-weight: normal;
}
So you have no "style" attributes in your HTML
If you want to hide panel on button click, write below code in JButton Action. I assume you want to hide jpanel1.

In gitk --all
:
Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)
It would be cool if gitk
had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.
Even if you're normally a command-line junkie like myself, git gui
and gitk
are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)
gitk
is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.
I don't even have a graphical file browser open, but I love gitk/git gui.
It sets the distance of the inset between the content view and the enclosing scroll view.
Obj-C
aScrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 7.0);
Swift 5.0
aScrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 7.0)
Here's a good iOS Reference Library article on scroll views that has an informative screenshot (fig 1-3) - I'll replicate it via text here:
_|?_cW_?_|_?_
| |
---------------
|content| ?
? |content| contentInset.top
cH |content|
? |content| contentInset.bottom
|content| ?
---------------
_|_______|___
?
(cH = contentSize.height; cW = contentSize.width)
The scroll view encloses the content view plus whatever padding is provided by the specified content insets.

@JustGoscha's answer is spot on, but that's a lot to type when I want access, so I added this to the bottom of my app.js. Then all I have to type is x = getSrv('$http')
to get the http service.
// @if DEBUG
function getSrv(name, element) {
element = element || '*[ng-app]';
return angular.element(element).injector().get(name);
}
// @endif
It adds it to the global scope but only in debug mode. I put it inside the @if DEBUG
so that I don't end up with it in the production code. I use this method to remove debug code from prouduction builds.
a=[]
for j in range(3):
a.append([int(i) for i in input().split()])
In this above code the given input i.e Mike 18 Kevin 35 Angel 56, will be stored in an array 'a' and gives the output as [['Mike', '18'], ['Kevin', '35'], ['Angel', '56']].
You can use the string formatting mini language:
def binary(num, pre='0b', length=8, spacer=0):
return '{0}{{:{1}>{2}}}'.format(pre, spacer, length).format(bin(num)[2:])
Demo:
print binary(1)
Output:
'0b00000001'
EDIT: based on @Martijn Pieters idea
def binary(num, length=8):
return format(num, '#0{}b'.format(length + 2))
To avoid 'Unclosed block: CssSyntaxError' errors being thrown from sass compilers add a ';' to the end of @content.
@mixin placeholder {
::-webkit-input-placeholder { @content;}
:-moz-placeholder { @content;}
::-moz-placeholder { @content;}
:-ms-input-placeholder { @content;}
}
To skip .
& ..
, you can use Dir::each_child
.
Dir.each_child('/path/to/dir') do |filename|
puts filename
end
Dir::children
returns an array of the filenames.
One thing that wasn't mentioned completely (although @BlooB kinda mentioned it) is that map returns a map object NOT a list. This is a big difference when it comes to time performance on initialization and iteration. Consider these two tests.
import time
def test1(iterable):
a = time.clock()
map(str, iterable)
a = time.clock() - a
b = time.clock()
[ str(x) for x in iterable ]
b = time.clock() - b
print(a,b)
def test2(iterable):
a = time.clock()
[ x for x in map(str, iterable)]
a = time.clock() - a
b = time.clock()
[ str(x) for x in iterable ]
b = time.clock() - b
print(a,b)
test1(range(2000000)) # Prints ~1.7e-5s ~8s
test2(range(2000000)) # Prints ~9s ~8s
As you can see initializing the map function takes almost no time at all. However iterating through the map object takes longer than simply iterating through the iterable. This means that the function passed to map() is not applied to each element until the element is reached in the iteration. If you want a list use list comprehension. If you plan to iterate through in a for loop and will break at some point, then use map.
For swedish Å Ä Ö the only solution form the ones above working was:
Encoding.GetEncoding("iso-8859-1")
Hopefully this will save someone time.
Options:
data.Seek
as suggested by ken2kUse the somewhat simpler Position
property:
data.Position = 0;
Use the ToArray
call in MemoryStream
to make your life simpler to start with:
byte[] buf = data.ToArray();
The third option would be my preferred approach.
Note that you should have a using
statement to close the file stream automatically (and optionally for the MemoryStream
), and I'd add a using directive for System.IO
to make your code cleaner:
byte[] buf;
using (MemoryStream data = new MemoryStream())
{
using (Stream file = TestStream())
{
file.CopyTo(data);
buf = data.ToArray();
}
}
// Use buf
You might also want to create an extension method on Stream
to do this for you in one place, e.g.
public static byte[] CopyToArray(this Stream input)
{
using (MemoryStream memoryStream = new MemoryStream())
{
input.CopyTo(memoryStream);
return memoryStream.ToArray();
}
}
Note that this doesn't close the input stream.
Table structure...very basic:
create table tabla(ID int, Stuff varchar (50));
insert into tabla values(1, '32.43');
insert into tabla values(2, '43.33');
insert into tabla values(3, '23.22');
Query:
SELECT SUM(cast(Stuff as decimal(4,2))) as result FROM tabla
Or, try this:
SELECT SUM(cast(isnull(Stuff,0) as decimal(12,2))) as result FROM tabla

To add on to chepner's answer for Python 3.0 you can alternatively do:
x = lambda x: list(map(print, x))
Of course this is only if you have the means of using Python > 3 in the future... Looks a bit cleaner in my opinion, but it also has a weird return value, but you're probably discarding it anyway.
I'll just leave this here for reference.
