You can do like this
$.datepicker.regional['fr'] = {clearText: 'Effacer', clearStatus: '',
closeText: 'Fermer', closeStatus: 'Fermer sans modifier',
prevText: '<Préc', prevStatus: 'Voir le mois précédent',
nextText: 'Suiv>', nextStatus: 'Voir le mois suivant',

monthNames: ['Janvier','Février','Mars','Avril','Mai','Juin',
'Juillet','Août','Septembre','Octobre','Novembre','Décembre'],
monthNamesShort: ['Jan','Fév','Mar','Avr','Mai','Jun',
'Jul','Aoû','Sep','Oct','Nov','Déc'],
monthStatus: 'Voir un autre mois', yearStatus: 'Voir un autre année',
weekHeader: 'Sm', weekStatus: '',
dayNames: ['Dimanche','Lundi','Mardi','Mercredi','Jeudi','Vendredi','Samedi'],
dayNamesShort: ['Dim','Lun','Mar','Mer','Jeu','Ven','Sam'],
dayNamesMin: ['Di','Lu','Ma','Me','Je','Ve','Sa'],
dayStatus: 'Utiliser DD comme premier jour de la semaine', dateStatus: 'Choisir le DD, MM d',
dateFormat: 'dd/mm/yy', firstDay: 0,
initStatus: 'Choisir la date', isRTL: false};
$.datepicker.setDefaults($.datepicker.regional['fr']);
In my case I had to wrap the bootstrapping of my second app in angular.element(document).ready
for it to work:
angular.element(document).ready(function() {
angular.bootstrap(document.getElementById("app2"), ["app2"]);
});
Along with Java 14, it starts supporting Record. You may want to check that https://docs.oracle.com/en/java/javase/14/docs/api/java.base/java/lang/Record.html
public record Person (String name, String address) {}
Person person = new Person("Esteban", "Stormhaven, Tamriel");
And there are Sealed Classes after Java 15. https://openjdk.java.net/jeps/360
sealed interface Shape permits Circle, Rectangle {
record Circle(Point center, int radius) implements Shape { }
record Rectangle(Point lowerLeft, Point upperRight) implements Shape { }
}
To make the border flash you can do this:
function focusTries() {
document.getElementById('tries').style.border = 'solid 1px #ff0000;'
setTimeout ( clearBorder(), 1000 );
}
function clearBorder() {
document.getElementById('tries').style.border = '';
}
This will make the border solid red for 1 second then remove it again.
Encountered similar issue, my server is behind nginx. There's no error in web server's (Python flask) log, but some error messsage in nginx log.
[crit] 31054#31054: *269464 open() "/var/cache/nginx/proxy_temp/3/45/0000000453" failed (13: Permission denied) while reading upstream
I fixed this issue by correcting the permission of directory:
/var/cache/nginx
You could query an LDAP server from the command line with ldap-utils: ldapsearch, ldapadd, ldapmodify
$.getJSON
is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.
Alternatively you could use jQuery's $.when/.then(), similar to this:
var input = "netuetamundis"; var sID; $(document).ready(function () { $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () { obj = name; sID = obj.id; console.log(sID); })).then(function () { $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) { console.log(stats); }); }); });
This would be more open for future modification and separates out the responsibility for the first call to know about the second call.
The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.
You might want to try the contains
selector:
if ($("#field > div.field-item:contains('someText')").length) {
$("#somediv").addClass("thisClass");
}
Also, as other mentioned, you must use == or === rather than =.
Just type the code and save it in .cpp format. then try "gcc filename.cpp" . This will create the object file. then try "./a.out" (This is the default object file name). If you want to know about gcc you can always try "man gcc"
Just to add to the list of options. You can also grab the object from the database, and use an auto mapping tool like Auto Mapper to update the parts of the record you want to change..
Here's where the exception occurs
((LinearLayout) linearLayout).addView(valueTV);
addView
method takes in a parameter of type View
, not TextView
. Therefore, typecast the valueTv object into a View object, explicitly.
Therefore, the corrected code would be :
((LinearLayout) linearLayout).addView((TextView)valueTV);
Use c_str() to convert the std::string to const char *.
cout << "String is : " << text.c_str() << endl ;
int a=7, b=7 ,c=0,d=0;
int dizi[][]=new int[a][b];
for(int i=0;i<a;i++){
for(int q=d;q<b;q++){
dizi[i][q]=c;
System.out.print(dizi[i][q]);
c++;
}
c-=b+1;
System.out.println();
}
result 0123456 -1012345 -2-101234 -3-2-10123 -4-3-2-1012 -5-4-3-2-101 -6-5-4-3-2-10
getApplicationContext() - Returns the context for all activities running in application.
getBaseContext() - If you want to access Context from another context within application you can access.
getContext() - Returns the context view only current running activity.
A couple of plain old foreach
loops provides a clean solution:
foreach (XElement level1Element in XElement.Load("data.xml").Elements("level1"))
{
result.AppendLine(level1Element.Attribute("name").Value);
foreach (XElement level2Element in level1Element.Elements("level2"))
{
result.AppendLine(" " + level2Element.Attribute("name").Value);
}
}
I was missing System.Data.Entity dll reference and problem was solved
I could be misinterpreting your question, but, yes, this is possible. The way that I would go about doing it is this:
var oElement = document.getElementById('elementId'); // get a reference to your element
oElement.onclick = clickHandler; // assign its click function a function reference
function clickHandler() {
// this function will be called whenever the element is clicked
// and can also be called from the context of other functions
}
Now, whenever this element is clicked, the code in clickHandler
will execute. Similarly, you can execute the same code by calling the function from within the context of other functions (or even assign clickHandler
to handle events triggered by other elements)>
it's because of your first column (Rows Header column) width ! increase it's width then you can see it's value ! you can use this command:
dgv1.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders;
(notice: you must first set dgv1.RowHeadersVisible = true;
)
The general rule I follow is not to include any header file unless I have to. So unless I am storing the object of a class as a member variable of my class I won't include it, I'll just use the forward declaration.
You can use date
to get time and date of a day:
[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013
Also hwclock
would do:
[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST -0.516080 seconds
For customized output, you can either redirect the output of date
to something like awk
, or write your own program to do that.
Remember to put your own executable scripts/binary into your PATH
(e.g. /usr/bin) to make it invokable anywhere.
You can use textwrap module to break it in multiple lines
import textwrap
str="ABCDEFGHIJKLIMNO"
print("\n".join(textwrap.wrap(str,8)))
ABCDEFGH
IJKLIMNO
From the documentation:
textwrap.wrap(text[, width[, ...]])
Wraps the single paragraph in text (a string) so every line is at most width characters long. Returns a list of output lines, without final newlines.Optional keyword arguments correspond to the instance attributes of
TextWrapper
, documented below. width defaults to70
.See the
TextWrapper.wrap()
method for additional details on how wrap() behaves.
To extend ko-dos' answer, here's an alias to list all container names and their IP addresses:
alias docker-ips='docker ps | tail -n +2 | while read -a a; do name=${a[$((${#a[@]}-1))]}; echo -ne "$name\t"; docker inspect $name | grep IPAddress | cut -d \" -f 4; done'
If all you want is the POST request body, you could use a method like this:
static String extractPostRequestBody(HttpServletRequest request) throws IOException {
if ("POST".equalsIgnoreCase(request.getMethod())) {
Scanner s = new Scanner(request.getInputStream(), "UTF-8").useDelimiter("\\A");
return s.hasNext() ? s.next() : "";
}
return "";
}

Nope... just use a DL:
dl { overflow:hidden; }
dt {
float:left;
clear: left;
width:4em; /* adjust the width; make sure the total of both is 100% */
text-align: right
}
dd {
float:left;
width:50%; /* adjust the width; make sure the total of both is 100% */
margin: 0 0.5em;
}
You should change your code to make use of SqlParameters and adapt your insert statement to the following
string connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;
// [ ] required as your fields contain spaces!!
string insStmt = "insert into Main ([First Name], [Last Name]) values (@firstName,@lastName)";
using (SqlConnection cnn = new SqlConnection(connetionString))
{
cnn.Open();
SqlCommand insCmd = new SqlCommand(insStmt, cnn);
// use sqlParameters to prevent sql injection!
insCmd.Parameters.AddWithValue("@firstName", textbox2.Text);
insCmd.Parameters.AddWithValue("@lastName", textbox3.Text);
int affectedRows = insCmd.ExecuteNonQuery();
MessageBox.Show (affectedRows + " rows inserted!");
}
The background color property is ignored on a UINavigationBar
, so if you want to adjust the look and feel you either have to use the tintColor
or call some of the other methods listed under "Customizing the Bar Appearance" of the UINavigationBar class reference (like setBackgroundImage:forBarMetrics:
).
Be aware that the tintColor
property works differently in iOS 7, so if you want a consistent look between iOS 7 and prior version using a background image might be your best bet. It's also worth mentioning that you can't configure the background image in the Storyboard, you'll have to create an IBOutlet
to your UINavigationBar
and change it in viewDidLoad
or some other appropriate place.
Weak references are collected eagerly. If GC finds that an object is weakly reachable (reachable only through weak references), it'll clear the weak references to that object immediately. As such, they're good for keeping a reference to an object for which your program also keeps (strongly referenced) "associated information" somewere, like cached reflection information about a class, or a wrapper for an object, etc. Anything that makes no sense to keep after the object it is associated with is GC-ed. When the weak reference gets cleared, it gets enqueued in a reference queue that your code polls somewhere, and it discards the associated objects as well. That is, you keep extra information about an object, but that information is not needed once the object it refers to goes away. Actually, in certain situations you can even subclass WeakReference and keep the associated extra information about the object in the fields of the WeakReference subclass. Another typical use of WeakReference is in conjunction with Maps for keeping canonical instances.
SoftReferences on the other hand are good for caching external, recreatable resources as the GC typically delays clearing them. It is guaranteed though that all SoftReferences will get cleared before OutOfMemoryError is thrown, so they theoretically can't cause an OOME[*].
Typical use case example is keeping a parsed form of a contents from a file. You'd implement a system where you'd load a file, parse it, and keep a SoftReference to the root object of the parsed representation. Next time you need the file, you'll try to retrieve it through the SoftReference. If you can retrieve it, you spared yourself another load/parse, and if the GC cleared it in the meantime, you reload it. That way, you utilize free memory for performance optimization, but don't risk an OOME.
Now for the [*]. Keeping a SoftReference can't cause an OOME in itself. If on the other hand you mistakenly use SoftReference for a task a WeakReference is meant to be used (namely, you keep information associated with an Object somehow strongly referenced, and discard it when the Reference object gets cleared), you can run into OOME as your code that polls the ReferenceQueue and discards the associated objects might happen to not run in a timely fashion.
So, the decision depends on usage - if you're caching information that is expensive to construct, but nonetheless reconstructible from other data, use soft references - if you're keeping a reference to a canonical instance of some data, or you want to have a reference to an object without "owning" it (thus preventing it from being GC'd), use a weak reference.
A small complement is:
My goal is to know wether a service is running without actualy running it if it is not running.
Calling bindService or calling an intent that can be caught by the service is not a good idea then as it will start the service if it is not running.
So, as miracle2k suggested, the best is to have a static field in the service class to know whether the service has been started or not.
To make it even cleaner, I suggest to transform the service in a singleton with a very very lazy fetching: that is, there is no instantiation at all of the singleton instance through static methods. The static getInstance method of your service/singleton just returns the instance of the singleton if it has been created. But it doesn't actualy start or instanciate the singleton itself. The service is only started through normal service start methods.
It would then be even cleaner to modify the singleton design pattern to rename the confusing getInstance method into something like the isInstanceCreated() : boolean
method.
The code will look like:
public class MyService extends Service
{
private static MyService instance = null;
public static boolean isInstanceCreated() {
return instance != null;
}//met
@Override
public void onCreate()
{
instance = this;
....
}//met
@Override
public void onDestroy()
{
instance = null;
...
}//met
}//class
This solution is elegant, but it is only relevant if you have access to the service class and only for classes iside the app/package of the service. If your classes are outside of the service app/package then you could query the ActivityManager with limitations underlined by Pieter-Jan Van Robays.
You can try:
select(data, matches("search_string"))
It is more general than contains
- you can use regex (e.g. "one_string|or_the_other"
).
For more examples, see: http://rpackages.ianhowson.com/cran/dplyr/man/select.html.
Logically there are no difference at all. Performance-wise there are -typically, on most DBMSes- no difference at all.
If you need an array, separate the array columns with a comma:
SELECT * FROM (VALUES('WOMENS'),('MENS'),('CHILDRENS')) as X([Attribute])
,(VALUES(742),(318)) AS z([StoreID])
public class TestDate {
public static void main(String[] args) {
// TODO Auto-generated method stub
String fromDate = "18-FEB-2018";
String toDate = "20-FEB-2018";
String requestDate = "19/02/2018";
System.out.println(checkBetween(requestDate,fromDate, toDate));
}
public static boolean checkBetween(String dateToCheck, String startDate, String endDate) {
boolean res = false;
SimpleDateFormat fmt1 = new SimpleDateFormat("dd-MMM-yyyy"); //22-05-2013
SimpleDateFormat fmt2 = new SimpleDateFormat("dd/MM/yyyy"); //22-05-2013
try {
Date requestDate = fmt2.parse(dateToCheck);
Date fromDate = fmt1.parse(startDate);
Date toDate = fmt1.parse(endDate);
res = requestDate.compareTo(fromDate) >= 0 && requestDate.compareTo(toDate) <=0;
}catch(ParseException pex){
pex.printStackTrace();
}
return res;
}
}
You can use If function Write in the cell where you want to input the date the following formula: =IF(MODIFIED-CELLNUMBER<>"",IF(CELLNUMBER-WHERE-TO-INPUT-DATE="",NOW(),CELLNUMBER-WHERE-TO-INPUT-DATE),"")
The below method worked for me, Kudos to github user : midnightcodr
Make sure You remove any nodejs/npm packages already installed.
sudo apt-get purge nodejs
sudo apt-get purge npm
Now Install Node js using the command below( Thanks to midnightcodr on github)
curl -L https://raw.github.com/midnightcodr/rpi_node_install/master/setup.sh | bash -s 0.10.24
Note that you can invoke node with command node and not nodejs.
Once node is installed , Install npm
sudo apt-get install npm

I wanted to share with you my solution to export a database with Microsoft SQL Server Management Studio.
To Export your database
DECLARE @BackupFile NVARCHAR(255);
SET @BackupFile = 'c:\database-backup_2020.07.22.bak';
PRINT @BackupFile;
BACKUP DATABASE [%databaseName%] TO DISK = @BackupFile;
Don't forget to replace %databaseName%
with the name of the database you want to export.
Note that this method gives a lighter file than from the menu.
To import this file from SQL Server Management Studio. Don't forget to delete your database beforehand.
Enjoy! :) :)
uint16_t
is unsigned 16-bit integer.
unsigned short int
is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX
is 65535
). In practice, it usually is 16-bit, but you can't take that as guaranteed.
Note:
uint16_t
.inttypes.h
and stdint.h
are both introduced in C99. If you are using C89, define your own type.uint16_t

late to the party, but if anyone comes across this, javascript has a encodeURI
method
you can try something like this, or just copy and past below piece.
boolean exception = true;
Charset charset = Charset.defaultCharset(); //Try the default one first.
int index = 0;
while(exception) {
try {
lines = Files.readAllLines(f.toPath(),charset);
for (String line: lines) {
line= line.trim();
if(line.contains(keyword))
values.add(line);
}
//No exception, just returns
exception = false;
} catch (IOException e) {
exception = true;
//Try the next charset
if(index<Charset.availableCharsets().values().size())
charset = (Charset) Charset.availableCharsets().values().toArray()[index];
index ++;
}
}
You need to actually run a webserver, and make the get request to a URI on that server, rather than making the get request to a file; e.g. change the line:
$.get("C:/xampp/htdocs/webname/resources/templates/signup.php",
to read something like:
$.get("http://localhost/resources/templates/signup.php",
and the initial request page needs to be made over http as well.
if c:\folder1\folder2\folder3\bin is the path then the following code will return the path base folder of bin folder
//string directory=System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString());
string directory=System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString();
ie,c:\folder1\folder2\folder3
if you want folder2 path then you can get the directory by
string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();
then you will get path as c:\folder1\folder2\

The hashcode will be calculated based on the ASCII values of the characters in the String.
This is the implementation in the String Class is as follows
public int hashCode() {
int h = hash;
if (h == 0 && value.length > 0) {
hash = h = isLatin1() ? StringLatin1.hashCode(value)
: StringUTF16.hashCode(value);
}
return h;
}
Collisions in hashcode are unavoidable. For example, the strings "Ea" and "FB" give the same hashcode as 2236
List<Customer> list = ...;
Customer john = list.SingleOrDefault(customer => customer.Firstname == "John");
john will be null if no customer exists with a first name of "John".
I think the only way to handle this is to use JavaScript
Try this Invert text color of a specific element
If you do this with css3 it's only compatible with the newest browser versions.
Two ways of doing it.
<asp:Calendar ID="planning" runat="server" SelectedDate="<%# DateTime.Now %>"></asp:Calendar>
protected void Page_Load(object sender, EventArgs e)
{
BindCalendar();
}
private void BindCalendar()

planning.SelectedDate = DateTime.Today;
}
Altough, I strongly recommend to do it from a BindMyStuff way. Single entry point easier to debug. But since you seems to know your game, you're all set.
I believe that, if you need to use the %20

There are two ways to do it: creating filter condition 1) Manually 2) Dynamically.
Sample DataFrame:
val df = spark.createDataFrame(Seq(
(0, "a1", "b1", "c1", "d1"),
(1, "a2", "b2", "c2", "d2"),
(2, "a3", "b3", null, "d3"),
(3, "a4", null, "c4", "d4"),
(4, null, "b5", "c5", "d5")
)).toDF("id", "col1", "col2", "col3", "col4")
+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
| 0| a1| b1| c1| d1|
| 1| a2| b2| c2| d2|
| 2| a3| b3|null| d3|
| 3| a4|null| c4| d4|
| 4|null| b5| c5| d5|
+---+----+----+----+----+
1) Creating filter condition manually i.e. using DataFrame where
or filter
function
df.filter(col("col1").isNotNull && col("col2").isNotNull).show
or
df.where("col1 is not null and col2 is not null").show
Result:
+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
| 0| a1| b1| c1| d1|
| 1| a2| b2| c2| d2|
| 2| a3| b3|null| d3|
+---+----+----+----+----+
2) Creating filter condition dynamically: This is useful when we don't want any column to have null value and there are large number of columns, which is mostly the case.
To create the filter condition manually in these cases will waste a lot of time. In below code we are including all columns dynamically using map
and reduce
function on DataFrame columns:
val filterCond = df.columns.map(x=>col(x).isNotNull).reduce(_ && _)
How filterCond
looks:
filterCond: org.apache.spark.sql.Column = (((((id IS NOT NULL) AND (col1 IS NOT NULL)) AND (col2 IS NOT NULL)) AND (col3 IS NOT NULL)) AND (col4 IS NOT NULL))
Filtering:
val filteredDf = df.filter(filterCond)
Result:
+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
| 0| a1| b1| c1| d1|
| 1| a2| b2| c2| d2|
+---+----+----+----+----+

What you have settled for is the best you can do:
public bool Foo<T>() where T : IBase;
JSONArray jsonArray = new JSONArray();
for (loop) {
JSONObject jsonObj= new JSONObject();
jsonObj.put("srcOfPhoto", srcOfPhoto);
jsonObj.put("username", "name"+count);
jsonObj.put("userid", "userid"+count);
jsonArray.put(jsonObj.valueToString());
}
JSONObject parameters = new JSONObject();
parameters.put("action", "remove");
parameters.put("datatable", jsonArray );
parameters.put(Constant.MSG_TYPE , Constant.SUCCESS);
Why were you using an Hashmap if what you wanted was to put it into a JSONObject?
EDIT: As per http://www.json.org/javadoc/org/json/JSONArray.html
EDIT2: On the JSONObject method used, I'm following the code available at: https://github.com/stleary/JSON-java/blob/master/JSONObject.java#L2327 , that method is not deprecated.
We're storing a string representation of the JSONObject, not the JSONObject itself
Contributed by Stephane CHAZELAS on c.u.s. Assuming POSIX shell:
prg=$0
if [ ! -e "$prg" ]; then
case $prg in

Just don't include the columns that you want to use the default value for in your insert statement. For instance:
INSERT INTO table1 (field1, field3) VALUES (5, 10);
...will take the default values for field2
and field4
, and assign 5 to field1
and 10 to field3
.
SELECT id, GROUP_CONCAT(CAST(name as CHAR)) FROM table GROUP BY id
Will give you a comma-delimited string
Sounds like you're trying to avoid passing a reference to this
into the method. Passing this
is way better than finding the caller through the current stack trace. Refactoring to a more OO design is even better. You shouldn't need to know the caller. Pass a callback object if necessary.
PowerShell comes with a built in command for it. So running directly from a .bat
file:
powershell -ExecutionPolicy ByPass -Command Send-MailMessage ^
-SmtpServer server.address.name ^
-To [email protected] ^
-From [email protected] ^
-Subject Testing ^
-Body 123
NB -ExecutionPolicy ByPass
is only needed if you haven't set up permissions for running PS from CMD
Also for those looking to call it from within powershell, drop everything before -Command
[inclusive], and `
will be your escape character (not ^
)
Are you trying to be distinct by more than one field? If so, just use an anonymous type and the Distinct operator and it should be okay:
var query = doc.Elements("whatever")
.Select(element => new {
id = (int) element.Attribute("id"),
category = (int) element.Attribute("cat") })
.Distinct();
If you're trying to get a distinct set of values of a "larger" type, but only looking at some subset of properties for the distinctness aspect, you probably want DistinctBy
as implemented in MoreLINQ in DistinctBy.cs
:
public static IEnumerable<TSource> DistinctBy<TSource, TKey>(
this IEnumerable<TSource> source,
Func<TSource, TKey> keySelector,
IEqualityComparer<TKey> comparer)
{
HashSet<TKey> knownKeys = new HashSet<TKey>(comparer);
foreach (TSource element in source)
{
if (knownKeys.Add(keySelector(element)))
{
yield return element;
}
}
}
(If you pass in null
as the comparer, it will use the default comparer for the key type.)

Your sample code won't work as shown because you forgot to include a Console.ReadLine()
before the serviceHost.Close()
line. That means the host is opened and then immediately closed.
Other than that, it seems you have a permission problem on your machine. Ensure you are logged-in as an administrator account on your machine. If you are an administrator then it may be that you don't have the World Wide Web Publishing Service (W3SVC) running to handle HTTP requests.
i wrote a simple function for this:
Function (stringVar param)
(
Local stringVar oneChar := '0';
Local numberVar strLen := Length(param);
Local numberVar index := strLen;
oneChar = param[strLen];
while index > 0 and oneChar = '0' do
(
oneChar := param[index];
index := index - 1;
);
Left(param , index + 1);
)
You don't need an IIF() at all here. The comparisons return true or false anyway.
Also, since this row visibility is on a group row, make sure you use the same aggregate function on the fields as you use in the fields in the row. So if your group row shows sums, then you'd put this in the Hidden property.
=Sum(Fields!OpeningStock.Value) = 0 And
Sum(Fields!GrossDispatched.Value) = 0 And
Sum(Fields!TransferOutToMW.Value) = 0 And
Sum(Fields!TransferOutToDW.Value) = 0 And
Sum(Fields!TransferOutToOW.Value) = 0 And
Sum(Fields!NetDispatched.Value) = 0 And
Sum(Fields!QtySold.Value) = 0 And
Sum(Fields!StockAdjustment.Value) = 0 And
Sum(Fields!ClosingStock.Value) = 0
But with the above version, if one record has value 1 and one has value -1 and all others are zero then sum is also zero and the row could be hidden. If that's not what you want you could write a more complex expression:
=Sum(
IIF(
Fields!OpeningStock.Value=0 AND
Fields!GrossDispatched.Value=0 AND
Fields!TransferOutToMW.Value=0 AND
Fields!TransferOutToDW.Value=0 AND
Fields!TransferOutToOW.Value=0 AND
Fields!NetDispatched.Value=0 AND
Fields!QtySold.Value=0 AND
Fields!StockAdjustment.Value=0 AND
Fields!ClosingStock.Value=0,
0,
1
)
) = 0
This is essentially a fancy way of counting the number of rows in which any field is not zero. If every field is zero for every row in the group then the expression returns true and the row is hidden.

which separates lines from each other (and discards empty lines)By using len() and those functions you could accomplish what you're doing.
On Mac (Postgres installed using brew) :

Getting encoding right is really tricky - there are too many layers:
The SQL command "SET CHARSET utf8" from PHP will ensure that the client side (PHP) will get the data in utf8, no matter how they are stored in the database. Of course, they need to be stored correctly first.
Encoding defined for a table/column doesn't really mean that the data are in that encoding. If you happened to have a table defined as utf8
but stored as differtent encoding, then MySQL will treat them as utf8
and you're in trouble. Which means you have to fix this first.
You need to check in what encoding the data flow at each layer.
If you receive data in e.g. windows-1250
, and want to store in utf-8
, then use this SQL before storing:
SET NAMES 'cp1250';
If you have data in DB as windows-1250
and want to retreive utf8
, use:
SET CHARSET 'utf8';
Having the following XML:
<node>Text1<subnode/>text2</node>
How do I select either the first or the second text node via XPath?
Use:
/node/text()
This selects all text-node children of the top element (named "node") of the XML document.
/node/text()[1]
This selects the first text-node child of the top element (named "node") of the XML document.
/node/text()[2]
This selects the second text-node child of the top element (named "node") of the XML document.
/node/text()[someInteger]
This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:
/node/text()[position() = someInteger]
You can also use the new HTML5 custom data- attributes.
<script type="text/javascript">
$(document).ready(function() {
$('.my_button').click(function() {
alert($(this).attr('data-value'));
});
});
</script>
<button class="my_button" name="buttonName" data-value="buttonValue">Button Label</button>
Yes, there are a number of ways that you can do this. The "fastest" way would be to add CSS to the div similar to the following
#term-defs {
height: 300px;
overflow: scroll; }
This will force the div to be scrollable, but this might not get the best effect. Another route would be to absolute fix the position of the items at the top, you can play with this by doing something like this.
#top {
position: fixed;
top: 0;
left: 0;
z-index: 999;
width: 100%;
height: 23px;
}
This will fix it to the top, on top of other content with a height of 23px.
The final implementation will depend on what effect you really want.
I just worked out a PostgreSQL-specific option for this. It's a bit of a hack, and comes with its own pros and cons and limitations, but it seems to work and isn't limited to a specific development language, platform, or PG driver.
The trick of course is to find a way to pass an arbitrary length collection of values as a single parameter, and have the db recognize it as multiple values. The solution I have working is to construct a delimited string from the values in the collection, pass that string as a single parameter, and use string_to_array() with the requisite casting for PostgreSQL to properly make use of it.
So if you want to search for "foo", "blah", and "abc", you might concatenate them together into a single string as: 'foo,blah,abc'. Here's the straight SQL:
select column from table
where search_column = any (string_to_array('foo,blah,abc', ',')::text[]);
You would obviously change the explicit cast to whatever you wanted your resulting value array to be -- int, text, uuid, etc. And because the function is taking a single string value (or two I suppose, if you want to customize the delimiter as well), you can pass it as a parameter in a prepared statement:
select column from table
where search_column = any (string_to_array($1, ',')::text[]);
This is even flexible enough to support things like LIKE comparisons:
select column from table
where search_column like any (string_to_array('foo%,blah%,abc%', ',')::text[]);
Again, no question it's a hack, but it works and allows you to still use pre-compiled prepared statements that take *ahem* discrete parameters, with the accompanying security and (maybe) performance benefits. Is it advisable and actually performant? Naturally, it depends, as you've got string parsing and possibly casting going on before your query even runs. If you're expecting to send three, five, a few dozen values, sure, it's probably fine. A few thousand? Yeah, maybe not so much. YMMV, limitations and exclusions apply, no warranty express or implied.
But it works.
no its a string with yyyy/mm/dd and i need it in yyyyMMdd format
If you only need to remove the slashes from a string don't you just replace them?
Example:
myDateString = "2013/03/28";
myDateString = myDateString.Replace("/", "");
myDateString should now be "20130328".
Less of an overkill :)
If you want to use the same date format among multiple threads, declare it as a static and synchronize on the instance variable when using it...
static private SimpleDateFormat sdf = new SimpleDateFormat("....");
synchronized(sdf)
{
// use the instance here to format a date
}
// The above makes it thread safe
The problem here is the performance, if you have a lot of rows it will be a problem.
If it is your case, please try with this:
import pandas as pd
source = pd.DataFrame({'Country' : ['USA', 'USA', 'Russia','USA'],
'City' : ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
'Short_name' : ['NY','New','Spb','NY']})
source.groupby(['Country','City']).agg(lambda x:x.value_counts().index[0])
source.groupby(['Country','City']).Short_name.value_counts().groupby['Country','City']).first()
There are other differences. For instance, {'time': datetime.now()}
cannot be serialized to JSON, but can be converted to string. You should use one of these tools depending on the purpose (i.e. will the result later be decoded).
I had a problem with the examples above, and the problem was caused by the fact that my select box values are prefilled with fixed length strings of 6 characters, but the parameter being passed in wasn't fixed length.
I have an rpad function which will right pad a string, to the length specified, and with the specified character. So, after padding the parameter it works.
$('#wsWorkCenter').val(rpad(wsWorkCenter, 6, ' '));
function rpad(pStr, pLen, pPadStr) {
if (pPadStr == '') {pPadStr == ' '};
while (pStr.length < pLen)
pStr = pStr + pPadStr;
return pStr;
}
In a bug I was investigating there was a Response.Redirect() and it was executing in an unexpected location (read: inappropriate location - inside a member property getter method).
If you're debugging a problem and experience the "Unable to evaluate expression..." exception:
Response.Redirect()
and either make the second parameter endResponse = false, orThis was frustrating as it would appear to execute the Redirect call before the "step through" on the debugger had reached that location.
Create a static method in the Fragment
and then get it using getArguments()
.
Example:
public class CommentsFragment extends Fragment {
private static final String DESCRIBABLE_KEY = "describable_key";
private Describable mDescribable;
public static CommentsFragment newInstance(Describable describable) {
CommentsFragment fragment = new CommentsFragment();
Bundle bundle = new Bundle();
bundle.putSerializable(DESCRIBABLE_KEY, describable);
fragment.setArguments(bundle);
return fragment;
}
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
mDescribable = (Describable) getArguments().getSerializable(
DESCRIBABLE_KEY);
// The rest of your code
}
You can afterwards call it from the Activity
doing something like:
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
Fragment fragment = CommentsFragment.newInstance(mDescribable);
ft.replace(R.id.comments_fragment, fragment);
ft.commit();
Yes IFNULL function will be working to achieve your desired result.
SELECT uo.order_id, uo.order_total, uo.order_status,
(SELECT IFNULL(SUM(uop.price * uop.qty),0)
FROM uc_order_products uop
WHERE uo.order_id = uop.order_id
) AS products_subtotal,
(SELECT IFNULL(SUM(upr.amount),0)
FROM uc_payment_receipts upr
WHERE uo.order_id = upr.order_id
) AS payment_received,
(SELECT IFNULL(SUM(uoli.amount),0)
FROM uc_order_line_items uoli
WHERE uo.order_id = uoli.order_id
) AS line_item_subtotal
FROM uc_orders uo
WHERE uo.order_status NOT IN ("future", "canceled")
AND uo.uid = 4172;
Thankfully, PHP developers aren't "Camel case bigots" like some development communities I know.
Your conventions sound fine.
Just so long as they're a) simple, and b) consistent - I don't see any problems :)
PS: Personally, I think 5) is overkill...

ln -s /path-text/of-symbolic-link /path/to/file-to-hold-that-text
The "ln" command creates a link-FILE, and the "-s" specifies that the type of link will be symbolic. An example of a symbolic-link file can be found in a WINE installation (using "ls -la" to show one line of the directory contents):
lrwxrwxrwx 1 me power 11 Jan 1 00:01 a: -> /mnt/floppy
Standard file-info stuff is at left (although note the first character is an "l" for "link"); the file-name is "a:" and the "->" also indicates the file is a link. It basically tells WINE how Windows "Drive A:" is to be associated with a floppy drive in Linux. To actually create a symbolic link SIMILAR to that (in current directory, and to actually do this for WINE is more complicated; use the "winecfg" utility):
ln -s /mnt/floppy a: //will not work if file a: already exists
Expanding on @Josh_Bode's answer, here's my own PyYAML solution, which has the advantage of being a self-contained subclass of yaml.Loader
. It doesn't depend on any module-level globals, or on modifying the global state of the yaml
module.
import yaml, os
class IncludeLoader(yaml.Loader):
"""
yaml.Loader subclass handles "!include path/to/foo.yml" directives in config
files. When constructed with a file object, the root path for includes
defaults to the directory containing the file, otherwise to the current
working directory. In either case, the root path can be overridden by the
`root` keyword argument.
When an included file F contain its own !include directive, the path is
relative to F's location.
Example:
YAML file /home/frodo/one-ring.yml:
---
Name: The One Ring
Specials:
- resize-to-wearer
Effects:
- !include path/to/invisibility.yml
YAML file /home/frodo/path/to/invisibility.yml:
---
Name: invisibility
Message: Suddenly you disappear!
Loading:
data = IncludeLoader(open('/home/frodo/one-ring.yml', 'r')).get_data()
Result:
{'Effects': [{'Message': 'Suddenly you disappear!', 'Name':
'invisibility'}], 'Name': 'The One Ring', 'Specials':
['resize-to-wearer']}
"""
def __init__(self, *args, **kwargs):
super(IncludeLoader, self).__init__(*args, **kwargs)
self.add_constructor('!include', self._include)
if 'root' in kwargs:
self.root = kwargs['root']
elif isinstance(self.stream, file):
self.root = os.path.dirname(self.stream.name)
else:
self.root = os.path.curdir
def _include(self, loader, node):
oldRoot = self.root
filename = os.path.join(self.root, loader.construct_scalar(node))
self.root = os.path.dirname(filename)
data = yaml.load(open(filename, 'r'))
self.root = oldRoot
return data
I have faced the same problem once too. I have solved it by creating on empty link with a ref to it like so:
linkRef = React.createRef();
render() {
return (
<a ref={this.linkRef}/>
);
}
and in my fetch function i have done something like this:
fetch(/*your params*/)
}).then(res => {
return res.blob();
}).then(blob => {
const href = window.URL.createObjectURL(blob);
const a = this.linkRef.current;
a.download = 'Lebenslauf.pdf';
a.href = href;
a.click();
a.href = '';
}).catch(err => console.error(err));
basically i have assigned the blobs url(href) to the link, set the download attribute and enforce one click on the link. As far as i understand this is the "basic" idea of the answer provided by @Nate. I dont know if this is a good idea to do it this way... I did.
In VS2008, the doc entry that seems the most useful is:
Windows Presentation Foundation Building a WPF Application (WPF)
ms-help://MS.VSCC.v90/MS.MSDNQTR.v90.en/wpf_conceptual/html/a58696fd-bdad-4b55-9759-136dfdf8b91c.htm
ApplicationDefinition Identifies the XAML markup file that contains the application definition (a XAML markup file whose root element is Application). ApplicationDefinition is mandatory when Install is true and OutputType is winexe. A WPF application and, consequently, an MSBuild project can only have one ApplicationDefinition.
Page Identifies a XAML markup file whose content is converted to a binary format and compiled into an assembly. Page items are typically implemented in conjunction with a code-behind class.
The most common Page items are XAML files whose top-level elements are one of the following:
Window (System.Windows..::.Window).
Page (System.Windows.Controls..::.Page).
PageFunction (System.Windows.Navigation..::.PageFunction<(Of <(T>)>)).
ResourceDictionary (System.Windows..::.ResourceDictionary).
FlowDocument (System.Windows.Documents..::.FlowDocument).
UserControl (System.Windows.Controls..::.UserControl).
Resource Identifies a resource file that is compiled into an application assembly. As mentioned earlier, UICulture processes Resource items.
Content Identifies a content file that is distributed with an application. Metadata that describes the content file is compiled into the application (using AssemblyAssociatedContentFileAttribute).
Use the instanceof
operator:
if(a instanceof MyClass)
{
//do something
}
I had a similar issue where I had 3 consecutive fragments in the same Activity
[M1.F0]->[M1.F1]->[M1.F2] followed by a call to a new Activity
[M2]. If the user pressed a button in [M2] I wanted to return to [M1,F1] instead of [M1,F2] which is what back press behavior already did.
In order to accomplish this I remove [M1,F2], call show on [M1,F1], commit the transaction, and then add [M1,F2] back by calling it with hide. This removed the extra back press that would have otherwise been left behind.
// Remove [M1.F2] to avoid having an extra entry on back press when returning from M2
final FragmentTransaction ftA = fm.beginTransaction();
ftA.remove(M1F2Fragment);
ftA.show(M1F1Fragment);
ftA.commit();
final FragmentTransaction ftB = fm.beginTransaction();
ftB.hide(M1F2Fragment);
ftB.commit();
Hi After doing this code: I'm not able to see value of Fragment2 on pressing Back Key. My Code:

ft.remove(f1);
ft.add(R.id.frame, f2);
ft.addToBackStack(null);
ft.remove(f2);
ft.add(R.id.frame, f3);
ft.commit();
@Override
public boolean onKeyDown(int keyCode, KeyEvent event){
if(keyCode == KeyEvent.KEYCODE_BACK){
Fragment currentFrag = getFragmentManager().findFragmentById(R.id.frame);
FragmentTransaction transaction = getFragmentManager().beginTransaction();
if(currentFrag != null){
String name = currentFrag.getClass().getName();
}
if(getFragmentManager().getBackStackEntryCount() == 0){
}
else{
getFragmentManager().popBackStack();
removeCurrentFragment();
}
}
return super.onKeyDown(keyCode, event);
}
public void removeCurrentFragment()
{
FragmentTransaction transaction = getFragmentManager().beginTransaction();
Fragment currentFrag = getFragmentManager().findFragmentById(R.id.frame);
if(currentFrag != null){
transaction.remove(currentFrag);
}
transaction.commit();
}
An alternative ist to use the short form of "concatenate" which is either "r_[...]" or "c_[...]" as shown in the example code beneath (see http://wiki.scipy.org/NumPy_for_Matlab_Users for additional information):
%pylab
vector_a = r_[0.:10.] #short form of "arange"
vector_b = array([1,1,1,1])
vector_c = r_[vector_a,vector_b]
print vector_a
print vector_b
print vector_c, '\n\n'
a = ones((3,4))*4

c = array([1,1,1])
b = c_[a,c]
print b, '\n\n'
a = ones((4,3))*4
print a, '\n'
c = array([[1,1,1]])
b = r_[a,c]

There is another option that does not introduce global gotchas when trying to initialize multiple variables to the same value. Whether or not it is preferable to the long way is a judgement call. It will likely be slower and may or may not be more readable. In your specific case, I think that the long way is probably more readable and maintainable as well as being faster.
The other way utilizes Destructuring assignment.
let [moveUp, moveDown,_x000D_
moveLeft, moveRight,_x000D_
mouseDown, touchDown] = Array(6).fill(false);_x000D_
_x000D_
console.log(JSON.stringify({_x000D_

moveLeft, moveRight,_x000D_
mouseDown, touchDown_x000D_
}, null, ' '));_x000D_
_x000D_
// NOTE: If you want to do this with objects, you would be safer doing this_x000D_
let [obj1, obj2, obj3] = Array(3).fill(null).map(() => ({}));_x000D_
console.log(JSON.stringify({_x000D_

This allows you to initialize a set of var
, let
, or const
variables to the same value on a single line all with the same expected scope.

This is actually a failure of design. You shouldn't be using a return value for anything not a primitive for anything that is not relatively trivial.
The ideal solution should be implemented through a return parameter with a decision on reference/pointer and the proper use of a "const\'y\'ness" as a descriptor.
On top of this, you should realise that the label on an array in C and C++ is effectively a pointer and its subscription are effectively an offset or an addition symbol.
So the label or ptr array_ptr === array label thus returning foo[offset] is really saying return element at memory pointer location foo + offset of type return type.

From Python documentation -> 8.3 Handling Exceptions:
A
try
statement may have more than one except clause, to specify handlers for different exceptions. At most one handler will be executed. Handlers only handle exceptions that occur in the corresponding try clause, not in other handlers of the same try statement. An except clause may name multiple exceptions as a parenthesized tuple, for example:except (RuntimeError, TypeError, NameError): pass
Note that the parentheses around this tuple are required, because except
ValueError, e:
was the syntax used for what is normally written asexcept ValueError as e:
in modern Python (described below). The old syntax is still supported for backwards compatibility. This meansexcept RuntimeError, TypeError
is not equivalent toexcept (RuntimeError, TypeError):
but toexcept RuntimeError as
TypeError:
which is not what you want.
in HQL you can use query parameter and set Collection with setParameterList method.
Query q = session.createQuery("SELECT entity FROM Entity entity WHERE name IN (:names)");
q.setParameterList("names", names);
For a strict Visual Basic approach, you can convert the floating-point value to an integer to round to said integer. VB is one of the rare languages that rounds on type conversion (most others simply truncate.)
Multiples of 5 or x can be done simply by dividing before and multiplying after the round.
If you want to round and keep decimal places, Math.round(n, d) would work.
Take a look at http://www.tingodb.com. I believe it does what you looking for. Additionally it fully compatible with MongoDB API. This reduces implementation risks and gives you option to switch to heavy solution as your app grows.
.gitconfig
I suggest using a .gitconfig
include for your aliases. Once you start creating aliases, you'll probably end up with a lot of them. They will likely be something you want to share with others. Putting them in a dedicated file makes it easy to share. Your team can even use a git repo to hold shared aliases. And of course some aliases you will not want to share, so keep them in a private alias file.

The 2019 optimal solution for this is HTTP/2 Server Push.
You do not need any hacky javascript solutions or inline styles. However, you do need a server that supports HTTP 2.0 (any modern server version will), which itself requires your server to run SSL. However, with Let's Encrypt there's no reason not to be using SSL anyway.
My site https://r.je/ has a 100/100 score for both mobile and desktop.
The reason for these errors is that the browser gets the HTML, then has to wait for the CSS to be downloaded before the page can be rendered. Using HTTP2 you can send both the HTML and the CSS at the same time.
You can use HTTP/2 push by setting the Link header.
Apache example (.htaccess):
Header add Link "</style.css>; as=style; rel=preload, </font.css>; as=style; rel=preload"
For NGINX you can add the header to your location tag in the server configuration:
location = / {
add_header Link "</style.css>; as=style; rel=preload, </font.css>; as=style; rel=preload";
}
With this header set, the browser receives the HTML and CSS at the same time which stops the CSS from blocking rendering.
You will want to tweak it so that the CSS is only sent on the first request, but the Link header is the most complete and least hacky solution to "Eliminate Render Blocking Javascript and CSS"
For a detailed discussion, take a look at my post here: Eliminate Render Blocking CSS using HTTP/2 Push
Please see Why does the property I want to mock need to be virtual?
You may have to write a wrapper interface or mark the property as virtual/abstract as Moq creates a proxy class that it uses to intercept calls and return your custom values that you put in the .Returns(x)
call.
Here the solution which worked for me when I had this issue in my local system.
You need to provide a candidate for autowire. That means that an instance of PasswordHint must be known to spring in a way that it can guess that it must reference it.
Please provide the class head of PasswordHint and/or the spring bean definition of that class for further assistance.
Try changing the name of
PasswordHintAction action;
to
PasswordHintAction passwordHintAction;
so that it matches the bean definition.
Ok, here is one try more. Using pseudo elements and aplying the shadow-box porperty over them.
html:

Maybe something like this:
SELECT count(*) FROM user_tab_columns WHERE table_name = 'FOO'
this will count number of columns in a the table FOO
You can also just
select count(*) from all_tab_columns where owner='BAR' and table_name='FOO';
where the owner is schema and note that Table Names are upper case
Recently at SXSWi 2012, in their "Mashery Lounge", there was a booth for an IMDB-like API called from rovi. It's not a free API, but according to the sales guy I talked to they offer either a rev share or a flat fee for usage, depending on your budget. I haven't used it yet but it seems pretty cool.
My understanding from my testing (and the PostgreSQL dox) is that the quotes need to be done differently from the other answers, and should also include "day" like this:
SELECT Table.date
FROM Table
WHERE date > current_date - interval '10 day';
Demonstrated here (you should be able to run this on any Postgres db):
SELECT DISTINCT current_date,
current_date - interval '10' day,
current_date - interval '10 days'
FROM pg_language;
Result:
2013-03-01 2013-03-01 00:00:00 2013-02-19 00:00:00
I searched a lot about restful ws security and we also ended up with using token via cookie from client to server to authenticate the requests . I used spring security for authorization of requests in service because I had to authenticate and authorized each request based on specified security policies that has already been in DB.
For JS:
First, if you haven't installed telegram bot just install with the command
npm i messaging-api-telegram
Now, initialize its client with
const client = new TelegramClient({
accessToken: process.env.<TELEGRAM_ACCESS_TOKEN>
});
Then, to send message use sendMessage() async function like below -
const resp = await client.sendMessage(chatId, msg, {
disableWebPagePreview: false,
disableNotification: false,
parseMode: "HTML"
});
Here parse mode by default would be plain text but with parseOptions parseMode we can do 1. "HTML" and "MARKDOWN" to let use send messages in stylish way. Also get your access token of bot from telegram page and chatId or group chat Id from same.
The onClick attribute of html tags only takes Javascript but not PHP code. However, you can easily call a PHP function from within the Javascript code by using the JS document.write() function - effectively calling the PHP function by "writing" its call to the browser window: Eg.
onclick="document.write('<?php //call a PHP function here ?>');"
Your example:
<?php
function hello(){
echo "Hello";
}
?>
<input type="button" name="Release" onclick="document.write('<?php hello() ?>');" value="Click to Release">
Edit 2018-02-06: revision based on this comment
Edit: forgot to mention that this works on Python 2.7.x
There's multiprocesing.pool, and the following sample illustrates how to use one of them:
from multiprocessing.pool import ThreadPool as Pool
# from multiprocessing import Pool
pool_size = 5 # your "parallelness"
# define worker function before a Pool is instantiated
def worker(item):
try:
api.my_operation(item)
except:
print('error with item')
pool = Pool(pool_size)
for item in items:
pool.apply_async(worker, (item,))
pool.close()
pool.join()
Now if you indeed identify that your process is CPU bound as @abarnert mentioned, change ThreadPool to the process pool implementation (commented under ThreadPool import). You can find more details here: http://docs.python.org/2/library/multiprocessing.html#using-a-pool-of-workers
I think it is not totally unrelated but did you consider canvas? something like Process JS can make it simpler.
Suppose the file you want to call is anotherfile.py and the method you want to call is method1, then first import the file and then the method
from anotherfile import method1
if method1 is part of a class, let the class be class1, then
from anotherfile import class1
then create an object of class1, suppose the object name is ob1, then
ob1 = class1()
ob1.method1()
You could use a Collector:
import java.util.*;
import java.util.stream.Collectors;
public class Defensive {
public static void main(String[] args) {
Map<String, Column> original = new HashMap<>();
original.put("foo", new Column());
original.put("bar", new Column());
Map<String, Column> copy = original.entrySet()
.stream()
.collect(Collectors.toMap(Map.Entry::getKey,
e -> new Column(e.getValue())));
System.out.println(original);
System.out.println(copy);
}
static class Column {
public Column() {}
public Column(Column c) {}
}
}
Based on your question, I think that you may be a bit confused about the difference between a User and a Login. A Login is an account on the SQL Server as a whole - someone who is able to log in to the server and who has a password. A User is a Login with access to a specific database.
Creating a Login is easy and must (obviously) be done before creating a User account for the login in a specific database:
CREATE LOGIN NewAdminName WITH PASSWORD = 'ABCD'
GO
Here is how you create a User with db_owner privileges using the Login you just declared:
Use YourDatabase;
GO
IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'NewAdminName')
BEGIN
CREATE USER [NewAdminName] FOR LOGIN [NewAdminName]
EXEC sp_addrolemember N'db_owner', N'NewAdminName'
END;
GO
Now, Logins are a bit more fluid than I make it seem above. For example, a Login account is automatically created (in most SQL Server installations) for the Windows Administrator account when the database is installed. In most situations, I just use that when I am administering a database (it has all privileges).
However, if you are going to be accessing the SQL Server from an application, then you will want to set the server up for "Mixed Mode" (both Windows and SQL logins) and create a Login as shown above. You'll then "GRANT" priviliges to that SQL Login based on what is needed for your app. See here for more information.
UPDATE: Aaron points out the use of the sp_addsrvrolemember to assign a prepared role to your login account. This is a good idea - faster and easier than manually granting privileges. If you google it you'll see plenty of links. However, you must still understand the distinction between a login and a user.
The answer is to DISABLE "Enable auto-completion on each input". Tested and works perfectly.
Also had this problem occurring on the web application surface. Eventually found out that the same error message comes from the SQL update statement in the specific table.
Finally then figured out that the column definition in the relating history table(s) did not map the original table column length of nvarchar
types in some specific cases.
I was experiencing a kind of similar issue:
System setup and Problem: (On a virtualbox I'm web hosting using ubuntu and nginx - PHP webpage refreshes did not reflect changes to external css file). I'm developing website on windows machine and transferring files to nginx via shared folder. It seems nginx does not pick up changes to css file (refreshing in any fashion does not help. Changing css file name is only thing that worked)
Solution: On VM find shared file (css file in my case). Open with nano and compare to file in windows share (they appear identical). On VM save shared file with nano. All changes are now reflected in browser. Not sure why this works but it did in my case.
UPDATE: After rebooting the VM server the problem returned. Following the instructions under Solution made the css responsive to updates again
Global variables certainly do exist in GAS, but you must understand the client/server relationship of the environment in order to use them correctly - please see this question: Global variables in Google Script (spreadsheet)
However this is not the problem with your code; the documentation indicates that the function to be executed by the menu must be supplied to the method as a string, right now you are supplying the output of the function: https://developers.google.com/apps-script/reference/spreadsheet/spreadsheet#addMenu%28String,Object%29
function MainMenu_Init() {
Logger.log('init');
};
function onOpen() {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var menus = [{
name: "Init",
functionName: "MainMenu_Init"
}];
spreadsheet.addMenu("Test", menus);
};
Following @JanKlimo example, on terminal all you have to do is:
to see all the Index:
$ curl -XGET 'http://127.0.0.1:9200/_cat/indices?v'
to see content of Index products_development_20160517164519304
:
$ curl -XGET 'http://127.0.0.1:9200/products_development_20160517164519304/_search?pretty=1'
You're comparing strings. JavaScript compares the ASCII code for each character of the string.
To see why you get false, look at the charCodes:
"1300".charCodeAt(0);
49
"999".charCodeAt(0);
57
The comparison is false because, when comparing the strings, the character codes for 1 is not greater than that of 9.
The fix is to treat the strings as numbers. You can use a number of methods:
parseInt(string, radix)
parseInt("1300", 10);
> 1300 - notice the lack of quotes
+"1300"
> 1300
Number("1300")
> 1300

Even if you do not have the pid, you can trigger 'wait;' after triggering all background processes. For. eg. in commandfile.sh-
bteq < input_file1.sql > output_file1.sql &
bteq < input_file2.sql > output_file2.sql &
bteq < input_file3.sql > output_file3.sql &
wait
Then when this is triggered, as -
subprocess.call(['sh', 'commandfile.sh'])
print('all background processes done.')
This will be printed only after all the background processes are done.
Let me seperate up everything and solve approach each problem in isolation:
Authentication
For authentication, baseauth has the advantage that it is a mature solution on the protocol level. This means a lot of "might crop up later" problems are already solved for you. For example, with BaseAuth, user agents know the password is a password so they don't cache it.
Auth server load
If you dispense a token to the user instead of caching the authentication on your server, you are still doing the same thing: Caching authentication information. The only difference is that you are turning the responsibility for the caching to the user. This seems like unnecessary labor for the user with no gains, so I recommend to handle this transparently on your server as you suggested.
Transmission Security
If can use an SSL connection, that's all there is to it, the connection is secure*. To prevent accidental multiple execution, you can filter multiple urls or ask users to include a random component ("nonce") in the URL.
url = username:[email protected]/api/call/nonce
If that is not possible, and the transmitted information is not secret, I recommend securing the request with a hash, as you suggested in the token approach. Since the hash provides the security, you could instruct your users to provide the hash as the baseauth password. For improved robustness, I recommend using a random string instead of the timestamp as a "nonce" to prevent replay attacks (two legit requests could be made during the same second). Instead of providing seperate "shared secret" and "api key" fields, you can simply use the api key as shared secret, and then use a salt that doesn't change to prevent rainbow table attacks. The username field seems like a good place to put the nonce too, since it is part of the auth. So now you have a clean call like this:
nonce = generate_secure_password(length: 16);
one_time_key = nonce + '-' + sha1(nonce+salt+shared_key);
url = username:[email protected]/api/call
It is true that this is a bit laborious. This is because you aren't using a protocol level solution (like SSL). So it might be a good idea to provide some kind of SDK to users so at least they don't have to go through it themselves. If you need to do it this way, I find the security level appropriate (just-right-kill).
Secure secret storage
It depends who you are trying to thwart. If you are preventing people with access to the user's phone from using your REST service in the user's name, then it would be a good idea to find some kind of keyring API on the target OS and have the SDK (or the implementor) store the key there. If that's not possible, you can at least make it a bit harder to get the secret by encrypting it, and storing the encrypted data and the encryption key in seperate places.
If you are trying to keep other software vendors from getting your API key to prevent the development of alternate clients, only the encrypt-and-store-seperately approach almost works. This is whitebox crypto, and to date, no one has come up with a truly secure solution to problems of this class. The least you can do is still issue a single key for each user so you can ban abused keys.
(*) EDIT: SSL connections should no longer be considered secure without taking additional steps to verify them.
Make sure SQL Server is enabled for TCP/IP (someone may have disabled it)?
This will also help you to check/verify the port number the SQL instance is using (in case someone changed it from the default of port 1433).
Obviously port 1433 (or whatever port SQL is listening on) needs to be unblocked by any firewalls between your machine and the box SQL is running on.
To check SQL's network configuration (requires SQL Server Client Tools installed): Start -> Programs -> SQL Server 200x -> Configuration Tools -> SQL Server Configuration Manager
Connect to the machine you need then expand the Tree Item (LHS) "SQL Server Network Configuration", then pick instance. You should have four options - Shared Memory, Named Pipes, TCP/IP and VIA. You can check that TCP/IP is enabled in the RHS window.
If you double click TCP/IP and hit the "Advanced" tab, you can also view the Port number.
Other thoughts.. Are you using SQL Authentication or Windows (Domain) authentication?
If SQL Authentication (which I assume you are using given you said username and password), are you sure the SQL instance you're connecting to has mixed mode authentication enabled? If not, you have to connect as Administrator and change the default security settings to allow SQL authentication.
If Windows Authentication, could your network be using Kerberos potentially? One would think the VPN credentials would be used for the handshake. I'd check your account has appropriate login rights.
You can use:
\\
That's ok, for example:
if (invName.substring(j,k).equals("\\")) {
copyf=invName.substring(0,j);
}
As you can see I only have java 1.7 installed (on a Ubuntu 14.04 machine).
update-java-alternatives -l
java-1.7.0-openjdk-amd64 1071 /usr/lib/jvm/java-1.7.0-openjdk-amd64
To install Java 8, I did,
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk
Afterwards, now I have java 7 and 8,
update-java-alternatives -l
java-1.7.0-openjdk-amd64 1071 /usr/lib/jvm/java-1.7.0-openjdk-amd64
java-1.8.0-openjdk-amd64 1069 /usr/lib/jvm/java-1.8.0-openjdk-amd64
BONUS ADDED (how to switch between different versions)
sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode 1 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode * 2 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1069 manual mode Press enter to keep the current choice[*], or type selection number:
As you can see I'm running open jdk 8. To switch to to jdk 7, press 1
and hit the Enter key. Do the same for javac
as well with, sudo update-alternatives --config javac
.
Check versions to confirm the change: java -version
and javac -version
.
To add to other answers. For me it was helpful to delete .mvn
directory and then add build.gradle
. New versions of IntelliJ will then automatically notice that you use Gradle.
Another Ionic way. Using this ion-buttons tag, and the right keyword puts all the buttons in this group to the right. I made some custom toggle buttons that i wanted on one line, but the group to be right justified.
<ion-buttons right>_x000D_
<button ....>1</button>_x000D_
<button ....>2</button>_x000D_
<button ....>3</button>_x000D_
</ion-buttons>

For this example, I have unchecked the Autolayout feature of the Interface builder. And, I'm still using (for no reason at all) the relatively old 4.6.1 version of Xcode.
Start with a view controller that has a scroll view over it (the main view).
1: Add a Container View, from the Object Library, to the scroll view. Notice that a new view controller is added to the storyboard and it is linked to the view controller with the scroll view.
2: Select the container view and, on the Size Inspector, make it anchor to top and left without auto resizing.
3: Change its height to 1000. (1000 is used for this example. You should apply the value that you require.)
4: Select the new view controller and, from the Attributes Inspector, change Size to Freeform.
5: Select the view of the new view controller and, on the size Inspector, change the height to 1000 (which is equal to the container view's height).
6: For your test later, while still on the view of the new view controller, add a label at the top and at the bottom of the view.
7: Select the scroll view from the original view controller. On the Identity inspector, add an attribute with the keyPath set to contentSize, type set to Size, and value set to {320, 1000} (or your container view's size).
8: Run on the 4-inch iPhone Simulator. You should be able to scroll from the top label up to the bottom label.
9: Run on the 3.5-inch iPhone Simulator. You should be able to scroll from the top label up to the bottom label.
Remember that Xcode 4.6.1 can only build for iOS6 and below. Using this approach and building for iOS6, I am still able to achieve the same results when the app is run on iOS7.
Another simple approach:
package org.yourpackagename;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(PreferenceController.class);
}
public static void main(String[] args) {
SpringApplication.run(PreferenceController.class, args);
}
}
You can create your view directly from the Layout Inflater, you only need to use the name of your layout XML file and the ID of the layout in file.
Your XML file should have an ID like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/dialog_layout_root"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
/>
And then you can set your layout on the builder with the following code:
LayoutInflater inflater = getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.dialog_layout, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();
If someone looking for a way to display decimal places even if it ends with ".00", use this:
String.Format("{0:n1}", value)

If you don't want to implement IEquatable, you can always use Reflection to compare all the properties: - if they're value type, just compare them -if they are reference type, call the function recursively to compare its "inner" properties.
I'm not thinking about performace, but about simplicity. It depends, however on the exact design of your objects. It could get complicated depending on your objects shape (for example if there are cyclic dependencies between properties). There are, however, several solutions out there that you can use, like this one:
Another option is to serialize the object as text, for example using JSON.NET, and comparing the serialization result. (JSON.NET can handle Cyclic dependencies between properties).
I don't know if by fastest you mean the fastest way to implement it or a code that runs fast. You should not optimize before knowing if you need to. Premature optimization is the root of all evil
It only works till 4000 byte, What if the clob is bigger than 4000 bytes then we use this
declare
v_clob_size clob;
begin
v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
DBMS_OUTPUT.put_line('CLOB Size ' || v_clob_size);
end;
or
select (DBMS_LOB.getlength(your_column_name))/1024/1024 from your_table
jQuery Validation Unobtrusive Native is a collection of ASP.Net MVC HTML helper extensions. These make use of jQuery Validation's native support for validation driven by HTML 5 data attributes. Microsoft shipped jquery.validate.unobtrusive.js back with MVC 3. It provided a way to apply data model validations to the client side using a combination of jQuery Validation and HTML 5 data attributes (that's the "unobtrusive" part).
Had the same problem on my Win10 PC with different packages and tried everything mentioned so far.
Finally solved it by disabling Comodo Auto-Containment.
Since nobody has mentioned it yet, I hope it helps someone.
You would basically want something along the lines of:
SELECT e.*, v.Score
FROM Evaluation e
LEFT JOIN Value v
ON v.CaseNum = e.CaseNum AND
v.FileNum = e.FileNum AND
v.ActivityNum = e.ActivityNum;
Remark: not too easy way, but workable and it has its own unique pros.
If one want to clone only HEAD
revision of a repository and only HEAD
s of all the its submodules (i.e. to checkout "trunk"), then one can use following Lua script. Sometimes simple command git submodule update --init --recursive --remote --no-fetch --depth=1
can result in an unrecoverable git
error. In this case one need to clean up subdirectory of .git/modules
directory and clone submodule manually using git clone --separate-git-dir
command. The only complexity is to find out URL, path of .git
directory of submodule and path of submodule in superproject tree.
Remark: the script is only tested against https://github.com/boostorg/boost.git
repository. Its peculiarities: all the submodules hosted on the same host and .gitmodules
contains only relative URLs.
-- mkdir boost ; cd boost ; lua ../git-submodules-clone-HEAD.lua https://github.com/boostorg/boost.git .
local module_url = arg[1] or 'https://github.com/boostorg/boost.git'
local module = arg[2] or module_url:match('.+/([_%d%a]+)%.git')
local branch = arg[3] or 'master'
function execute(command)
print('# ' .. command)
return os.execute(command)
end
-- execute('rm -rf ' .. module)
if not execute('git clone --single-branch --branch master --depth=1 ' .. module_url .. ' ' .. module) then
io.stderr:write('can\'t clone repository from ' .. module_url .. ' to ' .. module .. '\n')
return 1
end
-- cd $module ; git submodule update --init --recursive --remote --no-fetch --depth=1
execute('mkdir -p ' .. module .. '/.git/modules')
assert(io.input(module .. '/.gitmodules'))
local lines = {}
for line in io.lines() do
table.insert(lines, line)
end
local submodule
local path
local submodule_url
for _, line in ipairs(lines) do
local submodule_ = line:match('^%[submodule %"([_%d%a]-)%"%]$')
if submodule_ then
submodule = submodule_
path = nil
submodule_url = nil
else
local path_ = line:match('^%s*path = (.+)$')
if path_ then
path = path_
else
submodule_url = line:match('^%s*url = (.+)$')
end
if submodule and path and submodule_url then
-- execute('rm -rf ' .. path)
local git_dir = module .. '/.git/modules/' .. path:match('^.-/(.+)$')
-- execute('rm -rf ' .. git_dir)
execute('mkdir -p $(dirname "' .. git_dir .. '")')
if not execute('git clone --depth=1 --single-branch --branch=' .. branch .. ' --separate-git-dir ' .. git_dir .. ' ' .. module_url .. '/' .. submodule_url .. ' ' .. module .. '/' .. path) then
io.stderr:write('can\'t clone submodule ' .. submodule .. '\n')

public int getMax(ArrayList list){
int max = Integer.MIN_VALUE;
for(int i=0; i<list.size(); i++){

From my understanding, this is basically what Collections.max() does, though they use a comparator since lists are generic.
You've added a button to your DataGridView
and you want to run some code when it's clicked.
Easy peasy - just follow these steps:
First, here's what NOT to do:
I would avoid the suggestions in some of the other answers here and even provided by the documentation at MSDN to hardcode the column index or column name in order to determine if a button was clicked. The click event registers for the entire grid, so somehow you need to determine that a button was clicked, but you should not do so by assuming that your button lives in a particular column name or index... there's an easier way...
Also, be careful which event you want to handle. Again, the documentation and many examples get this wrong. Most examples handle the CellClick
event which will fire:
when any part of a cell is clicked.
...but will also fire whenever the row header is clicked. This necessitates adding extra code simply to determine if the e.RowIndex
value is less than 0
Instead handle the CellContentClick
which only occurs:
when the content within a cell is clicked
For whatever reason, the column header is also considered 'content' within a cell, so we'll still have to check for that below.
So here's what you should do:
First, cast the sender to type DataGridView
to expose it's internal properties at design time. You can modify the type on the parameter, but that can sometimes make adding or removing handlers tricky.
Next, to see if a button was clicked, just check to make sure that the column raising the event is of type DataGridViewButtonColumn
. Because we already cast the sender to type DataGridView
, we can get the Columns
collection and select the current column using e.ColumnIndex
. Then check if that object is of type DataGridViewButtonColumn
.
Of course, if you need to distinguish between multiple buttons per grid, you can then select based on the column name or index, but that shouldn't be your first check. Always make sure a button was clicked first and then handle anything else appropriately. In most cases where you only have a single button per grid, you can jump right off to the races.
C#:
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
var senderGrid = (DataGridView)sender;
if (senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn &&
e.RowIndex >= 0)
{
//TODO - Button Clicked - Execute Code Here
}
}
VB:
Private Sub DataGridView1_CellContentClick(sender As System.Object, e As DataGridViewCellEventArgs) _
Handles DataGridView1.CellContentClick
Dim senderGrid = DirectCast(sender, DataGridView)
If TypeOf senderGrid.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso
e.RowIndex >= 0 Then
'TODO - Button Clicked - Execute Code Here
End If
End Sub
If you wanted to have a little bit of fun, you can add your own event to be raised whenever a button is clicked on the DataGrid. You can't add it to the DataGrid itself, without getting messy with inheritance etc., but you can add a custom event to your form and fire it when appropriate. It's a little more code, but the upside is that you've separated out what you want to do when a button is clicked with how to determine if a button was clicked.
Just declare an event, raise it when appropriate, and handle it. It will look like this:
Event DataGridView1ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs)
Private Sub DataGridView1_CellContentClick(sender As System.Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim senderGrid = DirectCast(sender, DataGridView)
If TypeOf senderGrid.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso e.RowIndex >= 0 Then
RaiseEvent DataGridView1ButtonClick(senderGrid, e)
End If
End Sub
Private Sub DataGridView1_ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs) Handles Me.DataGridView1ButtonClick
'TODO - Button Clicked - Execute Code Here
End Sub
What would be great is if we were working with a grid that just did these things for us. We could answer the initial question easily: you've added a button to your DataGridView and you want to run some code when it's clicked
. Here's an approach that extends the DataGridView
. It might not be worth the hassle of having to deliver a custom control with every library, but at least it maximally reuses the code used for determining if a button was clicked.
Just add this to your assembly:
Public Class DataGridViewExt : Inherits DataGridView
Event CellButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs)
Private Sub CellContentClicked(sender As System.Object, e As DataGridViewCellEventArgs) Handles Me.CellContentClick
If TypeOf Me.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso e.RowIndex >= 0 Then
RaiseEvent CellButtonClick(Me, e)
End If
End Sub
End Class
That's it. Never touch it again. Make sure your DataGrid is of type DataGridViewExt
which should work exactly the same as a DataGridView. Except it will also raise an extra event that you can handle like this:
Private Sub DataGridView1_ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs) _
Handles DataGridView1.CellButtonClick
'TODO - Button Clicked - Execute Code Here
End Sub
Based on previous answers. I resolved my issue by removing global variable at package level to procedure, since there was no impact in my case.
Original script was
create or replace PACKAGE BODY APPLICATION_VALIDATION AS
V_ERROR_NAME varchar2(200) := '';
PROCEDURE APP_ERROR_X47_VALIDATION ( PROCESS_ID IN VARCHAR2 ) AS BEGIN
------ rules for validation... END APP_ERROR_X47_VALIDATION ;
/* Some more code
*/
END APPLICATION_VALIDATION; /
Rewritten the same without global variable V_ERROR_NAME
and moved to procedure under package level as
Modified Code
create or replace PACKAGE BODY APPLICATION_VALIDATION AS
PROCEDURE APP_ERROR_X47_VALIDATION ( PROCESS_ID IN VARCHAR2 ) AS
**V_ERROR_NAME varchar2(200) := '';**
BEGIN
------ rules for validation... END APP_ERROR_X47_VALIDATION ;
/* Some more code
*/
END APPLICATION_VALIDATION; /
First, you need to create selfsigned.key and selfsigned.crt files. Go to Create a Self-Signed SSL Certificate Or do following steps.
Go to the terminal and run the following command.
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./selfsigned.key -out selfsigned.crt
After creation adds key & cert file in your code, and pass the options to the server.
const express = require('express');
const https = require('https');
const fs = require('fs');
const port = 3000;
var key = fs.readFileSync(__dirname + '/../certs/selfsigned.key');
var cert = fs.readFileSync(__dirname + '/../certs/selfsigned.crt');
var options = {
key: key,
cert: cert
};
app = express()
app.get('/', (req, res) => {
res.send('Now using https..');
});
var server = https.createServer(options, app);
server.listen(port, () => {
console.log("server starting on port : " + port)
});

ReactDOM.render(<App/>,document.getElementById('root'));
Try this for Check Run-Time Permission:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
checkRunTimePermission();
}
Check run time permission:
private void checkRunTimePermission() {
String[] permissionArrays = new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE};
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissionArrays, 11111);
} else {
// if already permition granted
// PUT YOUR ACTION (Like Open cemara etc..)
}
}
Handle Permission result:
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
boolean openActivityOnce = true;
boolean openDialogOnce = true;
if (requestCode == 11111) {
for (int i = 0; i < grantResults.length; i++) {
String permission = permissions[i];
isPermitted = grantResults[i] == PackageManager.PERMISSION_GRANTED;
if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
// user rejected the permission
boolean showRationale = shouldShowRequestPermissionRationale(permission);
if (!showRationale) {
//execute when 'never Ask Again' tick and permission dialog not show
} else {
if (openDialogOnce) {
alertView();
}
}
}
}
if (isPermitted)
if (isPermissionFromGallery)
openGalleryFragment();
}
}
Set custom alert:
private void alertView() {
AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity(), R.style.MyAlertDialogStyle);
dialog.setTitle("Permission Denied")
.setInverseBackgroundForced(true)
//.setIcon(R.drawable.ic_info_black_24dp)
.setMessage("Without those permission the app is unable to save your profile. App needs to save profile image in your external storage and also need to get profile image from camera or external storage.Are you sure you want to deny this permission?")
.setNegativeButton("I'M SURE", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialoginterface, int i) {
dialoginterface.dismiss();
}
})
.setPositiveButton("RE-TRY", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialoginterface, int i) {

This version of flatten
avoids python's recursion limit (and thus works with arbitrarily deep, nested iterables). It is a generator which can handle strings and arbitrary iterables (even infinite ones).
import itertools as IT
import collections
def flatten(iterable, ltypes=collections.Iterable):
remainder = iter(iterable)
while True:
first = next(remainder)
if isinstance(first, ltypes) and not isinstance(first, (str, bytes)):
remainder = IT.chain(first, remainder)
else:
yield first
Here are some examples demonstrating its use:
print(list(IT.islice(flatten(IT.repeat(1)),10)))
# [1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
print(list(IT.islice(flatten(IT.chain(IT.repeat(2,3),
{10,20,30},
'foo bar'.split(),
IT.repeat(1),)),10)))
# [2, 2, 2, 10, 20, 30, 'foo', 'bar', 1, 1]
print(list(flatten([[1,2,[3,4]]])))
# [1, 2, 3, 4]
seq = ([[chr(i),chr(i-32)] for i in range(ord('a'), ord('z')+1)] + list(range(0,9)))
print(list(flatten(seq)))
# ['a', 'A', 'b', 'B', 'c', 'C', 'd', 'D', 'e', 'E', 'f', 'F', 'g', 'G', 'h', 'H',
# 'i', 'I', 'j', 'J', 'k', 'K', 'l', 'L', 'm', 'M', 'n', 'N', 'o', 'O', 'p', 'P',
# 'q', 'Q', 'r', 'R', 's', 'S', 't', 'T', 'u', 'U', 'v', 'V', 'w', 'W', 'x', 'X',
# 'y', 'Y', 'z', 'Z', 0, 1, 2, 3, 4, 5, 6, 7, 8]
Although flatten
can handle infinite generators, it can not handle infinite nesting:
def infinitely_nested():
while True:
yield IT.chain(infinitely_nested(), IT.repeat(1))
print(list(IT.islice(flatten(infinitely_nested()), 10)))
# hangs
:last-child
only works when the element in question is the last child of the container, not the last of a specific type of element. For that, you want :last-of-type

element, not the last element with the class of .comment
.

Procedures: 1.Procedures are the collections of statements that defines parameterized computations. 2.Procedures cannot return values.
3.Procedures cannot be called from function.
Functions 1.Functions structurally resemble procedures but are semantically modeled on mathematical functions. 2.It can return values 3.Function can be called from procedures.
Turning off optimization fixes the problem, but it is unnecessary. A safer alternative is to make it illegal for the compiler to optimize out the store by using the volatile
type qualifier.
// Assuming pageptr is unsigned char * already...
unsigned char *pageptr = ...;
((unsigned char volatile *)pageptr)[0] = pageptr[0];
The volatile
type qualifier instructs the compiler to be strict about memory stores and loads. One purpose of volatile
is to let the compiler know that the memory access has side effects, and therefore must be preserved. In this case, the store has the side effect of causing a page fault, and you want the compiler to preserve the page fault.
This way, the surrounding code can still be optimized, and your code is portable to other compilers which don't understand GCC's #pragma
or __attribute__
syntax.
As smnbss comments in Darin Dimitrov's answer, Prompt
exists for exactly this purpose, so there is no need to create a custom attribute. From the the documentation:
Gets or sets a value that will be used to set the watermark for prompts in the UI.
To use it, just decorate your view model's property like so:
[Display(Prompt = "numbers only")]
public int Age { get; set; }
This text is then conveniently placed in ModelMetadata.Watermark
. Out of the box, the default template in MVC 3 ignores the Watermark
property, but making it work is really simple. All you need to do is tweaking the default string template, to tell MVC how to render it. Just edit String.cshtml, like Darin does, except that rather than getting the watermark from ModelMetadata.AdditionalValues
, you get it straight from ModelMetadata.Watermark
:
~/Views/Shared/EditorTemplates/String.cshtml:
@Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new { @class = "text-box single-line", placeholder = ViewData.ModelMetadata.Watermark })
And that is it.
As you can see, the key to make everything work is the placeholder = ViewData.ModelMetadata.Watermark
bit.
If you also want to enable watermarking for multi-line textboxes (textareas), you do the same for MultilineText.cshtml:
~/Views/Shared/EditorTemplates/MultilineText.cshtml:
@Html.TextArea("", ViewData.TemplateInfo.FormattedModelValue.ToString(), 0, 0, new { @class = "text-box multi-line", placeholder = ViewData.ModelMetadata.Watermark })
You have invoked Ant with the verbose (-v) mode but the default buildfile build.xml
does not exist. Nor have you specified any other buildfile
for it to use.
I would say your Ant installation is fine.

What I've done is more clean and needs to make two arrays :
I initialize select2 using the first array as data, and the second as the val.
An example function with as parameters a dict of id:name.
function initMyList(values) {
var selected = [];
var initials = [];
for (var s in values) {
initials.push({id: s, name: values[s].name});
selected.push(s);
}
$('#myselect2').select2({
data: initials,
ajax: {
url: "/path/to/value/",
dataType: 'json',
delay: 250,
data: function (params) {
return {
term: params.term,
page: params.page || 1,
};
},
processResults: function (data, params) {
params.page = params.page || 1;
return {
results: data.items,
pagination: {
more: (params.page * 30) < data.total_count
}
};
},
cache: true
},
minimumInputLength: 1,
tokenSeparators: [",", " "],
placeholder: "Select none, one or many values",
templateResult: function (item) { return item.name; },
templateSelection: function (item) { return item.name; },
matcher: function(term, text) { return text.name.toUpperCase().indexOf(term.toUpperCase()) != -1; },
});
$('#myselect2').val(selected).trigger('change');
}
You can feed the initials value using ajax calls, and use jquery promises to do the select2 initialization.
Yes, as said by Thanakron Tandavas,
Recursion is good when you are solving a problem that can be solved by divide and conquer technique.
For example: Towers of Hanoi
In short, the answer is no. Once you show an alert
, confirm
, or prompt
the script no longer has control until the user returns control by clicking one of the buttons.
To do what you want, you will want to use DOM elements like a div
and show, then hide it after a specified time. If you need to be modal (takes over the page, allowing no further action) you will have to do additional work.
You could of course use one of the many "dialog" libraries out there. One that comes to mind right away is the jQuery UI Dialog widget
I had same problem. After one day, I got it.

The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.
Then you can use either _.size(object)
or _.keys(object).length
For your obj.Data
, you could test this with:
console.log( _.size(obj.Data) );
or:
console.log( _.keys(obj.Data).length );
Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)
Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:
function ObjectLength( object ) {
var length = 0;
for( var key in object ) {
if( object.hasOwnProperty(key) ) {
++length;
}
}
return length;
};
You can test this with:
console.log( ObjectLength(obj.Data) );
That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:
function ObjectLength_Modern( object ) {
return Object.keys(object).length;
}
function ObjectLength_Legacy( object ) {
var length = 0;
for( var key in object ) {
if( object.hasOwnProperty(key) ) {
++length;
}
}
return length;
}
var ObjectLength =
Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;
and as before, test it with:
console.log( ObjectLength(obj.Data) );
This code uses Object.keys(object).length
in modern browsers and falls back to counting in a loop for old browsers.
But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.
I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.
Thanks to Barmar for suggesting Object.keys
for newer browsers in his answer.
Choosing a random pivot minimizes the chance that you will encounter worst-case O(n2) performance (always choosing first or last would cause worst-case performance for nearly-sorted or nearly-reverse-sorted data). Choosing the middle element would also be acceptable in the majority of cases.
Also, if you are implementing this yourself, there are versions of the algorithm that work in-place (i.e. without creating two new lists and then concatenating them).
If you're trying to take advantage of polymorphic behavior, you need to ensure that the methods visible to outside classes (that need polymorphism) have the same signature. That means they need to have the same name, number and order of parameters, as well as the parameter types.
In your case, you might do better to have a generic draw()
method, and rely on the subclasses (Rectangle
, Ellipse
) to implement the draw()
method as what you had been thinking of as "drawEllipse" and "drawRectangle".
If all you want to do is to switch from inline plots to interactive and back (so that you can pan/zoom), it is better to use %matplotlib magic.
#interactive plotting in separate window
%matplotlib qt
and back to html
#normal charts inside notebooks
%matplotlib inline
%pylab magic imports a bunch of other things and may even result in a conflict. It does "from pylab import *".
You also can use new notebook backend (added in matplotlib 1.4):
#interactive charts inside notebooks, matplotlib 1.4+
%matplotlib notebook
If you want to have more interactivity in your charts, you can look at mpld3 and bokeh. mpld3 is great, if you don't have ton's of data points (e.g. <5k+) and you want to use normal matplotlib syntax, but more interactivity, compared to %matplotlib notebook . Bokeh can handle lots of data, but you need to learn it's syntax as it is a separate library.
Also you can check out pivottablejs (pip install pivottablejs)
from pivottablejs import pivot_ui
pivot_ui(df)
However cool interactive data exploration is, it can totally mess with reproducibility. It has happened to me, so I try to use it only at the very early stage and switch to pure inline matplotlib/seaborn, once I got the feel for the data.
You can select the shapes within a slide (Word Art also) and right click on the selection and choose "Save As Picture". It will save as a transparent PNG.
Given an environment where you have multiple developers accessing the same repository the following guidelines may help.
Ensure that you have a unix group that all devs belong to and give ownership of the .git repository to that group.
In the .git/config of the server repository set sharedrepository = true. (This tells git to allow multiple users which is needed for commits and deployment.
set the umask of each user in their bashrc files to be the same - 002 is a good start

sb.AppendLine(string.Join(",", fields));

fileSave.ShowDialog();
File.WriteAllText(fileSave.FileName, sb.ToString());
try{
BufferedReader br = new BufferedReader(new FileReader("textfile.txt"));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
// Print the content on the console
System.out.println (strLine);
}
//Close the input stream
in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}finally{
in.close();
}
This will read line by line,
If your no. are saperated by newline char. then in place of
System.out.println (strLine);
You can have
try{
int i = Integer.parseInt(strLine);
}catch(NumberFormatException npe){
//do something
}
If it is separated by spaces then
try{
String noInStringArr[] = strLine.split(" ");
//then you can parse it to Int as above
}catch(NumberFormatException npe){
//do something
}

By Changing The DbContext As Below;
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
}
Just adding in OnModelCreating
method call to base.OnModelCreating(modelBuilder); and it becomes fine. I am using EF6.

I just did this in v5.9.1. Just go to the Macro Menu, click "Start Recording", perform your 3 replace all commands, then stop recording. You can then select "Save Current Recorded Macro", and play it back as often as you like, and it will perform the replaces as you expect.

In 2020 Dec, the fix did finally worked for me was restarting my mac.
As others have said the first version, using "this" results in every instance of the class A having its own independent copy of function method "x". Whereas using "prototype" will mean that each instance of class A will use the same copy of method "x".
Here is some code to show this subtle difference:
// x is a method assigned to the object using "this"
var A = function () {
this.x = function () { alert('A'); };
};
A.prototype.updateX = function( value ) {
this.x = function() { alert( value ); }
};
var a1 = new A();
var a2 = new A();
a1.x(); // Displays 'A'
a2.x(); // Also displays 'A'
a1.updateX('Z');
a1.x(); // Displays 'Z'
a2.x(); // Still displays 'A'
// Here x is a method assigned to the object using "prototype"
var B = function () { };
B.prototype.x = function () { alert('B'); };
B.prototype.updateX = function( value ) {
B.prototype.x = function() { alert( value ); }
}
var b1 = new B();
var b2 = new B();
b1.x(); // Displays 'B'
b2.x(); // Also displays 'B'
b1.updateX('Y');
b1.x(); // Displays 'Y'
b2.x(); // Also displays 'Y' because by using prototype we have changed it for all instances
As others have mentioned, there are various reasons to choose one method or the other. My sample is just meant to clearly demonstrate the difference.
i had this same question a while back.. all types in ts are nullable, because void is a subtype of all types (unlike, for example, scala).
see if this flowchart helps - https://github.com/bcherny/language-types-comparison#typescript
You can use the JSON.parse()
for that.
Example:
var myObj = JSON.parse('{"p": 5}');
console.log(myObj);
Just struggled with Visutal Studio 2017 Community Edition - none of above options worked for me. In my case what i had to do was:
Run MySQL Installer and install/upgrade: Connector/NET and MySQL for Visual Studio to current versions (8.0.17 and 1.2.8 at the time)
Run Visual Studio Installer > Visual Studio Community 2017 > Modify > Individual components > add .NET Framework Targeting Packs for 4.6.2, 4.7, 4.7.1 and 4.7.2
Reopen project and change project target platform to 4.7.2
Remove all MySQL-related nuGET packages and references
Install following nuGET packages: EntityFramework, MySql.Data.Entity, Mysql.Data.Entities
Upgrade following nuGET packages: MySql.Data, BouncyCastle nad Google.Protobuf (for some reason there is an update available just after install)
The question has already been answered but I thought I would also let you know that rather than using the native PHP $_POST I reccomend you use the CodeIgniter input class so your controller code would be
function post_action()
{
if($this->input->post('textbox') == "")
{
$message = "You can't send empty text";
}
else
{
$message = $this->input->post('textbox');
}
echo $message;
}
assume min and max are int values, [ and ] means include this value, ( and ) means not include this value, using above to get the right value using c++ rand()
reference: for ()[] define, visit:
https://en.wikipedia.org/wiki/Interval_(mathematics)
for rand and srand function or RAND_MAX define, visit:
http://en.cppreference.com/w/cpp/numeric/random/rand
[min, max]
int randNum = rand() % (max - min + 1) + min
(min, max]
int randNum = rand() % (max - min) + min + 1
[min, max)
int randNum = rand() % (max - min) + min
(min, max)
int randNum = rand() % (max - min - 1) + min + 1
I know it's an old question but maybe someone can use this solution:
int size = 0; // Fill all bits with zero (0)
size = ~size; // Negate all bits, thus all bits are set to one (1)
So far we have -1 as result 'till size is a signed int.
size = (unsigned int)size >> 1; // Shift the bits of size one position to the right.
As Standard says, bits that are shifted in are 1 if variable is signed and negative and 0 if variable would be unsigned or signed and positive.
As size is signed and negative we would shift in sign bit which is 1, which is not helping much, so we cast to unsigned int, forcing to shift in 0 instead, setting the sign bit to 0 while letting all other bits remain 1.
cout << size << endl; // Prints out size which is now set to maximum positive value.
We could also use a mask and xor but then we had to know the exact bitsize of the variable. With shifting in bits front, we don't have to know at any time how many bits the int has on machine or compiler nor need we include extra libraries.
FYI
Using netbeans New Entity Classes from Database with a mysql *auto_increment* column, creates you an attribute with the following annotations:
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
@NotNull
private Integer id;
This was getting me the same an error saying the column must not be null, so i simply removed the @NotNull anotation leaving the attribute null, and it works!

Try this,.. :-)
Best practice is below according to the documentation:
{this.state.showFooter && <Footer />}
Render the element only when the state is valid.
You can run your node app by simply typing nodemon
It First run index.js
You can put your entry point in that file easily.
If you have not installed nodemon then you first you have to install it by
npm install -g nodemon
If you got any permission error then use
sudo npm install -g nodemon
You can check nodemon exists or not by
nodemon -v
It is most accurate to say that methods with a Bang! are the more dangerous or surprising version. There are many methods that mutate without a Bang such as .destroy
and in general methods only have bangs where a safer alternative exists in the core lib.
For instance, on Array we have .compact
and .compact!
, both methods mutate the array, but .compact!
returns nil instead of self if there are no nil's in the array, which is more surprising than just returning self.
The only non-mutating method I've found with a bang is Kernel
's .exit!
which is more surprising than .exit
because you cannot catch SystemExit
while the process is closing.
Rails and ActiveRecord continues this trend in that it uses bang for more 'surprising' effects like .create!
which raises errors on failure.
Echo the config: npm config ls
or npm config list
Show all the config settings: npm config ls -l
or npm config ls --json
Print the effective node_modules folder: npm root
or npm root -g
Print the local prefix: npm prefix
or npm prefix -g
(This is the closest parent directory to contain a package.json file or node_modules directory)
$()
means: "first evaluate this, and then evaluate the rest of the line".
Ex :
echo $(pwd)/myFile.txt
will be interpreted as
echo /my/path/myFile.txt
On the other hand ${}
expands a variable.
Ex:
MY_VAR=toto
echo ${MY_VAR}/myFile.txt
will be interpreted as
echo toto/myFile.txt
Why can't I use it as
bash$ while ((i=0;i<10;i++)); do echo $i; done
I'm afraid the answer is just that the bash syntax for while
just isn't the same as the syntax for for
.
Working with profiles is little tricky. Documentation can be found at: https://docs.aws.amazon.com/cli/latest/topic/config-vars.html (But you need to pay attention on env variables like AWS_PROFILE)
Using profile with aws cli requires a config file (default at ~/.aws/config
or set using AWS_CONFIG_FILE
).
A sample config file for reference:
`
[profile PROFILE_NAME]
output=json
region=us-west-1
aws_access_key_id=foo
aws_secret_access_key=bar
`
Env variable AWS_PROFILE
informs AWS cli about the profile to use from AWS config. It is not an alternate of config file like AWS_ACCESS_KEY_ID
/AWS_SECRET_ACCESS_KEY
are for ~/.aws/credentials
.
Another interesting fact is if AWS_PROFILE
is set and the AWS_ACCESS_KEY_ID
and AWS_SECRET_ACCESS_KEY
environment variables are set, then the credentials provided by AWS_ACCESS_KEY_ID
and AWS_SECRET_ACCESS_KEY
will override the credentials located in the profile provided by AWS_PROFILE
.

This is a classic example of how make a synchronous code snippet work asynchronously.
A class implements a method synchronously like the WebClient's DownloadData(…) function for example
(1) First wrap the method call in an Anonymous delegate.
(2) Use BeginInvoke(…) and send the wrapped anonymous delegate object as the last parameter along with a callback function name as the first parameter.
(3) In the callback method retrieve the ar's AsyncState as a Type (typecast) of the anonymous delegate. Along with this object comes EndInvoke(…) as free Gift
(4) Use EndInvoke(…) to retrieve the synchronous call’s return value in our case it will be the WebClient's DownloadData(…)’s return value.

You can try it:
ImageIcon imageIcon = new ImageIcon(new ImageIcon("icon.png").getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT));
label.setIcon(imageIcon);
Or in one line:
label.setIcon(new ImageIcon(new ImageIcon("icon.png").getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT)));
The execution time is much more faster than File and ImageIO.
I recommend you to compare the two solutions in a loop.
This is called RemoteApp. To use it you need to install Terminal Services, which is now called Remote Desktop Services.
Use these commands (in lucky case)
git remote -v
git pull
git fetch upstream
git checkout master
git merge upstream/master --no-ff
git add .
git commit -m"Sync with upstream repository."
git push -v
The two types are distinct in JavaScript as well as TypeScript - TypeScript just gives us syntax to annotate and check types as we go along.
String
refers to an object instance that has String.prototype
in its prototype chain. You can get such an instance in various ways e.g. new String('foo')
and Object('foo')
. You can test for an instance of the String
type with the instanceof
operator, e.g. myString instanceof String
.
string
is one of JavaScript's primitive types, and string
values are primarily created with literals e.g. 'foo'
and "bar"
, and as the result type of various functions and operators. You can test for string
type using typeof myString === 'string'
.
The vast majority of the time, string
is the type you should be using - almost all API interfaces that take or return strings will use it. All JS primitive types will be wrapped (boxed) with their corresponding object types when using them as objects, e.g. accessing properties or calling methods. Since String
is currently declared as an interface rather than a class in TypeScript's core library, structural typing means that string
is considered a subtype of String
which is why your first line passes compilation type checks.
