but is the css style tag the correct way to get cross browser compatibility?
<textarea style="display:none;" ></textarea>
or what I learned long ago....
<textarea hidden ></textarea>
or
the global hidden element method:
<textarea hidden="hidden" ></textarea>
You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable
page1.php
<?php
session_start();
$_SESSION['superhero'] = "batman";
?>
<a href="page2.php" title="">Go to the other page</a>
page2.php
<?php
session_start(); // this NEEDS TO BE AT THE TOP of the page before any output etc
echo $_SESSION['superhero'];
?>
To multiply, use mult
for signed multiplication and multu
for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0
that means that you assume the result will fit in 32 bits.
The 32 most significant bits will be held in the HI
special register (accessible by mfhi
instruction) and the 32 least significant bits will be held in the LO
special register (accessible by the mflo
instruction):
E.g.:
li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0
To divide, use div
for signed division and divu
for unsigned division. In this case, the HI
special register will hold the remainder and the LO
special register will hold the quotient of the division.
E.g.:
div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

Assuming maven project:
Properties file should be in src/main/resources/database
folder
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password
hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true
ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.
Let's say you have package name a.b.c.service.impl
. MyServiceImpl is in this package and so is ServiceMarker.
public interface ServiceMarker {
}
Same for repository marker. Let's say you have a.b.c.repository.impl
or a.b.c.dao.impl
package name. Then MyDaoImpl is in this this package and also Repositorymarker
public interface RepositoryMarker {
}
//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {
private LocalDateTime fromDate;
private LocalDateTime toDate;
//getters setters
}
@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {
@Override
public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {
if (dateTime == null) {
return null;
}
return Timestamp.valueOf(dateTime);
}
@Override
public LocalDateTime convertToEntityAttribute(Timestamp timestamp) {
if (timestamp == null) {
return null;

return timestamp.toLocalDateTime();

Hope it helps. Thanks
The curly braces mean concatenation, from most significant bit (MSB) on the left down to the least significant bit (LSB) on the right. You are creating a 32-bit bus (result) whose 16 most significant bits consist of 16 copies of bit 15 (the MSB) of the a bus, and whose 16 least significant bits consist of just the a bus (this particular construction is known as sign extension, which is needed e.g. to right-shift a negative number in two's complement form and keep it negative rather than introduce zeros into the MSBits).
There is a tutorial here*, but it doesn't explain too much more than the above paragraph.
For what it's worth, the nested curly braces around a[15:0]
are superfluous.
*Beware: the example within the tutorial link contains a typo when demonstrating multiple concatenations - the (2{C}}
should be a {2{2}}
.
This worked for me:
Seems like something went south when I originally created the site. I hate solutions that are similar to "Restart your machine, then reinstall windows" without knowing what caused the error. But, this worked for me. Quick and simple. Hope it helps someone else.
The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc
A set of simple examples:
Using Gson:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
public class Gson {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
com.google.gson.Gson gson = new com.google.gson.Gson();
Response respuesta = gson.fromJson(json, Response.class);
System.out.println(respuesta.getExample());
System.out.println(respuesta.getFr());
} catch (IOException ex) {
}
return null;
}
public class Response{
private String example;
private String fr;
public String getExample() {
return example;
}
public void setExample(String example) {
this.example = example;
}
public String getFr() {
return fr;
}
public void setFr(String fr) {
this.fr = fr;
}
}
}
Using json-simple:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class JsonSimple {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
try {
JSONParser parser = new JSONParser();
Object resultObject = parser.parse(json);
if (resultObject instanceof JSONArray) {
JSONArray array=(JSONArray)resultObject;
for (Object object : array) {
JSONObject obj =(JSONObject)object;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
}else if (resultObject instanceof JSONObject) {
JSONObject obj =(JSONObject)resultObject;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
} catch (Exception e) {
// TODO: handle exception
}
} catch (IOException ex) {
}
return null;
}
}
etc...
Early versions allowed root password to be blank but, in Newer versions set the root password is the admin(main) user login password during the installation.
Set data to this:
data ={"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}
Try this:
$sql = mysql_query("SELECT SUM(Value) as total FROM Codes");
$row = mysql_fetch_array($sql);
$sum = $row['total'];
why can't I use a property like self.myView
instead of a local variable like myView?
try using:
NSDictionaryOfVariableBindings(_view)
instead of self.view
How about putting all content inside link?
<li><a href="#" onClick="..." ... >Backpack <img ... /></a></li>
Seems like the most natural thing to try.
Alternative solution is to use the Warehouse APIs:
https://warehouse.readthedocs.io/api-reference/json/#release
For instance for Flask:
import requests
r = requests.get("https://pypi.org/pypi/Flask/json")
print(r.json()['releases'].keys())
will print:
dict_keys(['0.1', '0.10', '0.10.1', '0.11', '0.11.1', '0.12', '0.12.1', '0.12.2', '0.12.3', '0.12.4', '0.2', '0.3', '0.3.1', '0.4', '0.5', '0.5.1', '0.5.2', '0.6', '0.6.1', '0.7', '0.7.1', '0.7.2', '0.8', '0.8.1', '0.9', '1.0', '1.0.1', '1.0.2'])
CSS selector:
Use a CSS selector of img[src='images/toolbar/b_edit.gif']
This says select element(s) with img
tag with attribute src
having value of 'images/toolbar/b_edit.gif'
CSS query:
VBA:
You can apply the selector with the .querySelector
method of document
.
IE.document.querySelector("img[src='images/toolbar/b_edit.gif']").Click
You should write your own stream manipulator
cout << multi(5) << "whatever" << "lolcat";
Edit: Apparently the solution is very easy, and doesn't need any JavaScript. Just create a new cell at the bottom having the following line:
while True:pass
now keep the cell in the run sequence so that the infinite loop won't stop and thus keep your session alive.
Old method: Set a javascript interval to click on the connect button every 60 seconds. Open developer-settings (in your web-browser) with Ctrl+Shift+I then click on console tab and type this on the console prompt. (for mac press Option+Command+I)
function ConnectButton(){
console.log("Connect pushed");
document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click()
}
setInterval(ConnectButton,60000);
In Angular 2+, you can set route to default page by adding this route to your route module. In this case login is my target route for the default page.
{path:'',redirectTo:'login', pathMatch: 'full' },
There are a couple of possibilities. One I like uses a stringstream as a go-between:
std::ifstream t("file.txt");
std::stringstream buffer;
buffer << t.rdbuf();
Now the contents of "file.txt" are available in a string as buffer.str()
.
Another possibility (though I certainly don't like it as well) is much more like your original:
std::ifstream t("file.txt");
t.seekg(0, std::ios::end);
size_t size = t.tellg();
std::string buffer(size, ' ');
t.seekg(0);
t.read(&buffer[0], size);
Officially, this isn't required to work under the C++98 or 03 standard (string isn't required to store data contiguously) but in fact it works with all known implementations, and C++11 and later do require contiguous storage, so it's guaranteed to work with them.
As to why I don't like the latter as well: first, because it's longer and harder to read. Second, because it requires that you initialize the contents of the string with data you don't care about, then immediately write over that data (yes, the time to initialize is usually trivial compared to the reading, so it probably doesn't matter, but to me it still feels kind of wrong). Third, in a text file, position X in the file doesn't necessarily mean you'll have read X characters to reach that point -- it's not required to take into account things like line-end translations. On real systems that do such translations (e.g., Windows) the translated form is shorter than what's in the file (i.e., "\r\n" in the file becomes "\n" in the translated string) so all you've done is reserved a little extra space you never use. Again, doesn't really cause a major problem but feels a little wrong anyway.
Rename pub/local.xml.sample into local.xml . then i will show you exactly error.
You don't need hibernate-entitymanager-xxx.jar
, because of you use a Hibernate session approach (not JPA
). You need to close the SessionFactory
too and rollback a transaction on errors. But, the problem, of course, is not with those.
This is returned by a database
#
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "sa"

Looks like you've provided an incorrect username or (and) password.
If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:
sudo nano .bashrc
chmod 777 .bashrc
it is worthless
<div id="container">
<img style="width: 100%; height: 40%;" id="image" src="...">
</div>
I hope this will serve your purpose.
Simple answer to this; I was trying to figure out the same thing, and it just hit me.
GitHub IS a program installed on your computer, and when it runs, it WILL use threads and RAM. So that makes it a process. All you have to do is open Task Manager, click the Processes tab, find 'Github.exe', right click, Open File Location. Voila! Mine is in some App folder in Local, about 4 layers deep.
You're comparing apples to oranges here:
webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service
basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.
So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).
Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:
basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security
wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network
For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding
You could use the JPA LOCATE function.
LOCATE(searchString, candidateString [, startIndex]): Returns the first index of searchString in candidateString. Positions are 1-based. If the string is not found, returns 0.
FYI: The documentation on my top google hit had the parameters reversed.
SELECT
e
FROM
entity e
WHERE
(0 < LOCATE(:searchStr, e.property))

After reading all the answers here, and seeing the complexity described, I set upon a small diversion for experimenting with HR. And, the conclusion is that you can throw out most of the monkeypatched CSS you wrote, read this small primer and just use these two lines of pure CSS:
hr {
border-style: solid;
border-color: cornflowerblue; /* or whatever */
}
That is ALL you need to style your HRs.
height
, width
, background-color
, color
, etc. involved.Just bulletproof colourful HRs. It's that simpleTM.
Bonus: To give the HR some height H
, just set the border-width
as H/2
.
Select e.lastname as employee ,m.lastname as manager
from employees e,employees m
where e.managerid=m.employyid(+)
nothing much to add,
1 - if you want to execute a query in a loop (more than 1 time), prepared statement can be faster, because of optimization that you mentioned.
2 - parameterized query is a good way to avoid SQL Injection. Parameterized querys are only available in PreparedStatement.
I think this should be a simple example:
$('#item1 span').text();
or
$('#item1 span').html();
You can delete
one of your layout files
(does not matter which one), after that you need to build project
. Project will build and after that you need to return your layout file by CTRL + Z. In my case, if I tried to build my project before deleting of layout file
, it did not help me. But this way is ok.
To add to wflynny's answer above, you can find the available colormaps here
Example:
import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.jet)
or alternatively,
plt.scatter(x, y, c=t, cmap='jet')
Use the GD library or ImageMagick. I googled 'PHP GD merge images' and got several articles on doing this. In the past what I've done is create a large blank image, and then used imagecopymerge() to paste those images into my original blank one. Check out the articles on google you'll find some source code you can start using right away.
The keyword "Selection" is already a vba Range object so you can use it directly, and you don't have to select cells to copy, for example you can be on Sheet1 and issue these commands:
ThisWorkbook.worksheets("sheet2").Range("namedRange_or_address").Copy
ThisWorkbook.worksheets("sheet1").Range("namedRange_or_address").Paste
If it is a multiple selection you should use the Area object in a for loop:
Dim a as Range
For Each a in ActiveSheet.Selection.Areas
a.Copy
ThisWorkbook.worksheets("sheet2").Range("A1").Paste
Next

If you use jquery, it can be done by using $(window).height();
<iframe src="html_intro.asp" width="100%" class="myIframe">
<p>Hi SOF</p>
</iframe>
<script type="text/javascript" language="javascript">
$('.myIframe').css('height', $(window).height()+'px');
</script>

Because all attempts to print the argument I placed in my variable failed, here my 2 bytes for this question:
std::string dump_name;
(stuff..)
if(argc>2)

dump_name.assign(argv[2]);
fprintf(stdout, "ARGUMENT %s", dump_name.c_str());

Note the use of assign, and also the need for the c_str() function call.

I have the same problem. This error occurs because conection pooling. When exists two or more users acess the system the connetion pooling reuse a connetion and the transation too. If the first user execute commit ou rollback the transaction is no longe usable.
I've tried a select statement now with a PreparedStatement
, but it turned out that it was not faster than the Jdbc template. Maybe, as mezmo suggested, it automatically creates prepared statements.
Anyway, the reason for my sql SELECT
s being so slow was another one. In the WHERE
clause I always used the operator LIKE
, when all I wanted to do was finding an exact match. As I've found out LIKE
searches for a pattern and therefore is pretty slow.
I'm using the operator =
now and it's much faster.
I face the same problem. After reading numerous posts, I would like to introduce the following solution I finally chose over many other methods (e.g. use urllib
, httpimport
, clone from GitHub, package the modules for installation, etc). The solution utilizes Google Drive API (official doc) for proper authorization.
id=
" - the file id assigned by Google Drive!pip install pydrive # Package to use Google Drive API - not installed in Colab VM by default
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth # Other necessary packages
from oauth2client.client import GoogleCredentials
auth.authenticate_user() # Follow prompt in the authorization process
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)
your_module = drive.CreateFile({"id": "your_module_file_id"}) # "your_module_file_id" is the part after "id=" in the shareable link
your_module.GetContentFile("your_module_file_name.py") # Save the .py module file to Colab VM
import your_module_file_name # Ready to import. Don't include".py" part, of course :)
Last but not least, I should credit the original contributor of this approach. That post might have some typo in the code as it triggered an error when I tried it. After more reading and troubleshooting my code snippets above worked (as of today on Colab VM OS: Linux 4.14.79).
select datename(DAY,GETDATE()) +'-'+ datename(MONTH,GETDATE()) +'- '+
datename(YEAR,GETDATE()) as 'yourcolumnname'
You can get current login customer name from session in following way :
$customer = Mage::getSingleton('customer/session')->getCustomer();
This will return the customer details of current login customer.
Now you can get customer name by using getName()
echo $customer->getName();
I'm using CSS Dig. It is made for chrome, but I think it is a great tool!
Declare them outside the subroutines, like this:
Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
Set wbA = Workbooks.Open("C:\file.xlsx")
Set wbB = Workbooks.Open("C:\file2.xlsx")
OtherSubRoutine
End Sub
Sub OtherSubRoutine()
MsgBox wbA.Name, vbInformation
End Sub
Alternately, you can pass variables between subroutines:
Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
Set wbA = Workbooks.Open("C:\file.xlsx")
Set wbB = Workbooks.Open("C:\file2.xlsx")
OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
MsgBox wb1.Name, vbInformation
MsgBox wb2.Name, vbInformation
End Sub
Or use Functions
to return values:
Sub MySubroutine()
Dim i as Long
i = MyFunction()
MsgBox i
End Sub
Function MyFunction()
'Lots of code that does something
Dim x As Integer, y as Double
For x = 1 to 1000
'Lots of code that does something
Next
MyFunction = y
End Function
In the second method, within the scope of OtherSubRoutine
you refer to them by their parameter names wb1
and wb2
. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.
A Note About User Forms
Personally I would recommend keeping Option Explicit
in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn
when you meant lCount
etc., among other reasons).
If you're using Option Explicit
(which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public
scoped variables, as these are not "public" in the same sense. For instance, i
is undefined, though it's Public
in the scope of UserForm1
:
You can refer to it as UserForm1.i
to avoid the compile error, or since forms are New
-able, you can create a variable object to contain reference to your form, and refer to it that way:
NB: In the above screenshots x
is declared Public x as Long
in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x
to avoid ambiguity and possible shadowing in case you re-use variable names...
In my case having loadView() interrupted
this code:
self.edgesForExtendedLayout = UIRectEdgeNone
but after deleting loadView() everything worked fine
So as to have another possibility1 to find the files that are executable by the current user:
find . -type f -exec test -x {} \; -print
(the test command here is the one found in PATH, very likely /usr/bin/test
, not the builtin).
1 Only use this if the -executable
flag of find
is not available! this is subtly different from the -perm +111
solution.
There has been many helpful answers here, generally culminating into two points.
AND as @MichaelBerkowski said
Backticks are to be used for table and column identifiers, but are only necessary when the identifier is a
MySQL
reserved keyword, or when the identifier contains whitespace characters or characters beyond a limited set (see below) It is often recommended to avoid using reserved keywords as column or table identifiers when possible, avoiding the quoting issue.
There is a case though where an identifier can neither be a reserved keyword or contain whitespace or characters beyond limited set but necessarily require backticks around them.
EXAMPLE
123E10
is a valid identifier name but also a valid INTEGER
literal.
[Without going into detail how you would get such an identifier name], Suppose I want to create a temporary table named 123456e6
.
No ERROR on backticks.
DB [XXX]> create temporary table `123456e6` (`id` char (8));
Query OK, 0 rows affected (0.03 sec)
ERROR when not using backticks.
DB [XXX]> create temporary table 123451e6 (`id` char (8));
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '123451e6 (`id` char (8))' at line 1
However, 123451a6
is a perfectly fine identifier name (without back ticks).
DB [XXX]> create temporary table 123451a6 (`id` char (8));
Query OK, 0 rows affected (0.03 sec)
This is completely because 1234156e6
is also an exponential number.
In a web-based database application that uses a pop-up window to display print-outs of database data, this worked well enough for our needs (tested in Chrome 48):
<form method="post"
target="print_popup"
action="/myFormProcessorInNewWindow.aspx"
onsubmit="window.open('about:blank','print_popup','width=1000,height=800');">
The trick is to match the target
attribute on the <form>
tag with the second argument in the window.open
call in the onsubmit
handler.
If you happen to be using tcomb-form-native
as I am, you can do this, too. Here's the trick: instead of setting the props of the TextInput
directly, you do it via options
. You can refer to the fields of the form as:
this.refs.form.getComponent('password').refs.input.focus()
So the final product looks something like this:
var t = require('tcomb-form-native');
var Form = t.form.Form;
var MyForm = t.struct({
field1: t.String,
field2: t.String,
});
var MyComponent = React.createClass({
_getFormOptions () {
return {
fields: {
field1: {
returnKeyType: 'next',
onSubmitEditing: () => {this.refs.form.getComponent('field2').refs.input.focus()},
},
},
};
},
render () {
var formOptions = this._getFormOptions();
return (
<View style={styles.container}>
<Form ref="form" type={MyForm} options={formOptions}/>
</View>
);
},
});
(Credit to remcoanker for posting the idea here: https://github.com/gcanti/tcomb-form-native/issues/96)
For adding borders try this, for example:
Range("C11").Borders(xlEdgeRight).LineStyle = xlContinuous
Range("A15:D15").Borders(xlEdgeBottom).LineStyle = xlContinuous
Hope that syntax is correct because I've done this in C#.
//get the parentfolder name
File file = new File( System.getProperty("user.dir") + "/.");
String parentPath = file.getParentFile().getName();
Example: say you have an 'image' you want to scale you will need a bufferedImage probably, and probably will be starting out with just 'Image' object. So this works I think... The AVATAR_SIZE is the target width we want our image to be:
Image imgData = image.getScaledInstance(Constants.AVATAR_SIZE, -1, Image.SCALE_SMOOTH);
BufferedImage bufferedImage = new BufferedImage(imgData.getWidth(null), imgData.getHeight(null), BufferedImage.TYPE_INT_RGB);
bufferedImage.getGraphics().drawImage(imgData, 0, 0, null);
This one worked for me getBaseContext();
When I think my code isn't unit tested enough, and I'm not sure what to test next, I use coverage to help me decide what to test next.
If I increase coverage in a unit test - I know this unit test worth something.
This goes for code that is not covered, 50% covered or 97% covered.
This code will work for all cases:
int[] a1 ={3,4,5,6};
int[] a2 = {4,7,9};
int i = a1.Length-1;
int j = a2.Length-1;
int resultIndex= i+j+1;
Array.Resize(ref a2, a1.Length +a2.Length);
while(resultIndex >=0)
{
if(i != 0 && j !=0)
{
if(a1[i] > a2[j])
{
a2[resultIndex--] = a[i--];
}
else
{
a2[resultIndex--] = a[j--];
}
}
else if(i>=0 && j<=0)
{
a2[resultIndex--] = a[i--];
}
else if(j>=0 && i <=0)
{
a2[resultIndex--] = a[j--];
}
}

Using flexbox:
HTML:
<div class="wrapper">
<img src="pikachu.gif"/>
</div>
CSS:
.wrapper {
height: 300px;
width: 300px;
display: flex;
align-items: flex-end;
}
As requested in some comments on another answer, the image can also be horizontally centred with justify-content: center;
I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
I think this is what you're looking for. NEW_BAL
is the sum of QTY
s subtracted from the balance:
SELECT master_table.ORDERNO,
master_table.ITEM,
SUM(master_table.QTY),
stock_bal.BAL_QTY,
(stock_bal.BAL_QTY - SUM(master_table.QTY)) AS NEW_BAL
FROM master_table INNER JOIN
stock_bal ON master_bal.ITEM = stock_bal.ITEM
GROUP BY master_table.ORDERNO,
master_table.ITEM
If you want to update the item balance with the new balance, use the following:
UPDATE stock_bal
SET BAL_QTY = BAL_QTY - (SELECT SUM(QTY)
FROM master_table
GROUP BY master_table.ORDERNO,
master_table.ITEM)
This assumes you posted the subtraction backward; it subtracts the quantities in the order from the balance, which makes the most sense without knowing more about your tables. Just swap those two to change it if I was wrong:
(SUM(master_table.QTY) - stock_bal.BAL_QTY) AS NEW_BAL
In some cases, you need to force refresh the view in order to make it work.
toggleButton.setTextOff(textOff);
toggleButton.requestLayout();
toggleButton.setTextOn(textOn);
toggleButton.requestLayout();
SELECT *
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(MONTH, -3, GETDATE())
Mureinik's suggested method will return the same results, but doing it this way your query can benefit from any indexes on Date_Column
.
or you can check against last 90 days.
SELECT *
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(DAY, -90, GETDATE())
You are confuising two CSS styles, the display style and the visibility style.
If the element is hidden by setting the visibility css style, then you should be able to get the height regardless of whether or not the element is visible or not as the element still takes space on the page.
If the element is hidden by changing the display css style to "none", then the element doesn't take space on the page, and you will have to give it a display style which will cause the element to render in some space, at which point, you can get the height.
You can use a TextBox
and set multiline
to true
and canEdit
to false
.
If you want to replace a char in a string with an empty char that means you want to remove that char from a string, read the answer of R. Martinho Fernandes.
Here is an exemple of how to remove a char from a string (replace with an "Empty char"):
public static string RemoveCharFromString(string input, char charItem)
{
int indexOfChar = input.IndexOf(charItem);
if (indexOfChar >= 0)
{
input = input.Remove(indexOfChar, 1);
}
return input;
}
or this version that removes all recurrences of a char in a string :
public static string RemoveCharFromString(string input, char charItem)
{
int indexOfChar = input.IndexOf(charItem);
if (indexOfChar < 0)
{
return input;
}
return RemoveCharFromString(input.Remove(indexOfChar, 1), charItem);
}
Did you took a look at this? http://developer.yahoo.com/yui/history/
The only reason I can think of for using a numerical index in a set would be for iteration. For that, use
for(A a : set) {
visit(a);
}
You have an error in your code. This line:
for(int i=0;i<v[n];i++)
should be
for(int i=0;i<n;i++)
because you want to search n
places in your vector, not v[n]
places (which wouldn't mean anything)
It sounds like you want to convert the rownames to a proper column of the data.frame. eg:
# add the rownames as a proper column
myDF <- cbind(Row.Names = rownames(myDF), myDF)
myDF
# Row.Names id val vr2
# row_one row_one A 1 23
# row_two row_two A 2 24
# row_three row_three B 3 25
# row_four row_four C 4 26
If you want to then remove the original rownames:
rownames(myDF) <- NULL
myDF
# Row.Names id val vr2
# 1 row_one A 1 23
# 2 row_two A 2 24
# 3 row_three B 3 25
# 4 row_four C 4 26
Alternatively, if all of your data is of the same class (ie, all numeric, or all string), you can convert to Matrix and name the dimnames
myMat <- as.matrix(myDF)
names(dimnames(myMat)) <- c("Names.of.Rows", "")
myMat
# Names.of.Rows id val vr2
# row_one "A" "1" "23"
# row_two "A" "2" "24"
# row_three "B" "3" "25"
# row_four "C" "4" "26"
Here's technique I figured out after a bit of trial and error that allows you to preserve your XML styles and avoid the issues of using a <merge/>
(i.e. inflate() requires a merge to attach to root, and returns the root node). No runtime new TableRow()
s or new TextView()
s required.
Code
Note: Here CheckBalanceActivity
is some sample Activity
class
TableLayout table = (TableLayout)CheckBalanceActivity.this.findViewById(R.id.attrib_table);
for(ResourceBalance b : xmlDoc.balance_info)
{
// Inflate your row "template" and fill out the fields.
TableRow row = (TableRow)LayoutInflater.from(CheckBalanceActivity.this).inflate(R.layout.attrib_row, null);
((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME);
((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE);
table.addView(row);
}
table.requestLayout(); // Not sure if this is needed.
attrib_row.xml
<?xml version="1.0" encoding="utf-8"?>
<TableRow style="@style/PlanAttribute" xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
style="@style/PlanAttributeText"
android:id="@+id/attrib_name"
android:textStyle="bold"/>
<TextView
style="@style/PlanAttributeText"
android:id="@+id/attrib_value"
android:gravity="right"
android:textStyle="normal"/>
</TableRow>
By passing a block to find_or_create
, you can pass additional parameters that will be added to the object if it is created new. This is useful if you are validating the presence of a field that you aren't searching by.
Assuming:
class GroupMember < ActiveRecord::Base
validates_presence_of :name
end
then
GroupMember.where(:member_id => 4, :group_id => 7).first_or_create { |gm| gm.name = "John Doe" }
will create a new GroupMember with the name "John Doe" if it doesn't find one with member_id 4
and group_id 7
The LINEST function described in a previous answer is the way to go, but an easier way to show the 3 coefficients of the output is to additionally use the INDEX function. In one cell, type: =INDEX(LINEST(B2:B21,A2:A21^{1,2},TRUE,FALSE),1) (by the way, the B2:B21 and A2:A21 I used are just the same values the first poster who answered this used... of course you'd change these ranges appropriately to match your data). This gives the X^2 coefficient. In an adjacent cell, type the same formula again but change the final 1 to a 2... this gives the X^1 coefficient. Lastly, in the next cell over, again type the same formula but change the last number to a 3... this gives the constant. I did notice that the three coefficients are very close but not quite identical to those derived by using the graphical trendline feature under the charts tab. Also, I discovered that LINEST only seems to work if the X and Y data are in columns (not rows), with no empty cells within the range, so be aware of that if you get a #VALUE error.
If you're using @ConfigurationProperties
with Spring Boot 2 to inject maps with keys that contain colons then you need an additional level of escaping using square brackets inside the quotes because spring only allows alphanumeric and '-' characters, stripping out the rest. Your new key would look like this:
"[8.11.32.120:8000]": GoogleMapsKeyforThisDomain
See this github issue for reference.
I know it's an old question but it shows up high on google search results and the answers provided here are not really in C++ or are a bit too complicated.
Please note that in my example createDirTree() is very simple because all the heavy lifting (error checking, path validation) needs to be done by createDir() anyway. Also createDir() should return true if directory already exists or the whole thing won't work.
Here's how I would do that in C++:
#include <iostream>
#include <string>
bool createDir(const std::string dir)
{
std::cout << "Make sure dir is a valid path, it does not exist and create it: "
<< dir << std::endl;
return true;
}
bool createDirTree(const std::string full_path)
{
size_t pos = 0;
bool ret_val = true;
while(ret_val == true && pos != std::string::npos)
{
pos = full_path.find('/', pos + 1);
ret_val = createDir(full_path.substr(0, pos));
}
return ret_val;
}
int main()
{
createDirTree("/tmp/a/b/c");
return 0;
}
Of course createDir() function will be system-specific and there are already enough examples in other answers how to write it for linux, so I decided to skip it.
Since 3.5, anything inherited from System.Collection.IEnumerable has the convenient extension method OfType available.
If your collection is from ICollection or IEnumerable, you can just do this:
List<ManagementObject> managementList = ManagementObjectCollection.OfType<ManagementObject>().ToList();
Can't find any way simpler. : )
Well, I am still stumped. So here is more code.
Before I leave my map, I call SaveLocation(myMapView,myMapController);
This is what ends up calling my geocoding information.
But since getFromLocation
can throw an IOException
, I had to do the following to call SaveLocation
try
{
SaveLocation(myMapView,myMapController);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
Then I have to change SaveLocation by saying it throws IOExceptions :
public void SaveLocation(MapView mv, MapController mc) throws IOException{
//I do this :
Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());
List myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
//...
}
And it crashes every time.
Had the same problem with a zipcode field. Some folks sent me an excel file with zips, but they were formatted as #'s. Had to convert them to strings as well as prepend leading 0's to them if they were < 5 len ...
declare @int tinyint
set @int = 25
declare @len tinyint
set @len = 3
select right(replicate('0', @len) + cast(@int as varchar(255)), @len)
You just alter the @len to get what you want. As formatted, you'll get...
001
002
...
010
011
...
255
Ideally you'd "varchar(@len)", too, but that blows up the SQL compile. Have to toss an actual # into it instead of a var.
This code works, can you compare it with yours?

Similar to Yipio, I added notab="notab"
as an attribute to any element I wanted to disable the tab too. My jQuery is then one line.

I am new to retrofit and I am enjoying it. So here is a simple way to understand it for those that might want to query with more than one query: The ? and & are automatically added for you.
Interface:
public interface IService {
String BASE_URL = "https://api.test.com/";
String API_KEY = "SFSDF24242353434";
@GET("Search") //i.e https://api.test.com/Search?
Call<Products> getProducts(@Query("one") String one, @Query("two") String two,
@Query("key") String key)
}
It will be called this way. Considering you did the rest of the code already.
Call<Results> call = service.productList("Whatever", "here", IService.API_KEY);
For example, when a query is returned, it will look like this.
//-> https://api.test.com/Search?one=Whatever&two=here&key=SFSDF24242353434

A TreeMap
is always sorted by the keys, anything else is impossible. A Comparator
merely allows you to control how the keys are sorted.
If you want the sorted values, you have to extract them into a List
and sort that.
Dictionaries are specifically designed to do super fast key lookups. They are implemented as hashtables and the more entries the faster they are relative to other methods. Using the exception engine is only supposed to be done when your method has failed to do what you designed it to do because it is a large set of object that give you a lot of functionality for handling errors. I built an entire library class once with everything surrounded by try catch blocks once and was appalled to see the debug output which contained a seperate line for every single one of over 600 exceptions!
First of all - that selector is pretty slow. It will scan every DOM element looking for the ids. It will be less of a performance hit if you can assign a class to the element.
$(".myselect")
To answer your question though, there are a few ways to change the select elements value in jQuery
// sets selected index of a select box to the option with the value "0"
$("select#elem").val('0');
// sets selected index of a select box to the option with the value ""
$("select#elem").val('');
// sets selected index to first item using the DOM
$("select#elem")[0].selectedIndex = 0;
// sets selected index to first item using jQuery (can work on multiple elements)
$("select#elem").prop('selectedIndex', 0);
First I did alias setup on bash / zsh profile.
alias composer="php /usr/local/bin/composer.phar"
Then I moved composer.phar to /usr/local/bin/
cd /usr/local/bin
mv composer.phar composer
Then made composer executable by running
sudo chmod +x composer
Much easier
//Now Create all of the directories
foreach (string dirPath in Directory.GetDirectories(SourcePath, "*",
SearchOption.AllDirectories))
Directory.CreateDirectory(dirPath.Replace(SourcePath, DestinationPath));
//Copy all the files & Replaces any files with the same name
foreach (string newPath in Directory.GetFiles(SourcePath, "*.*",
SearchOption.AllDirectories))
File.Copy(newPath, newPath.Replace(SourcePath, DestinationPath), true);
I don't know of any way to access a mobile phone's camera from the web browser without some additional mechanism (i.e. Flash or some type of container that allows access to the hardware API)
For the latter have a look at PhoneGap: http://docs.phonegap.com/phonegap_camera_camera.md.html
With this you should be able to access the camera at least on iOS and Android-based devices.
I have found that if you don't put the variable directly against the scope it updates more reliably.
Try using some "dateObj.selectedDate" and in the controller add the selectedDate to a dateObj object as so:
$scope.dateObj = {selectedDate: new Date()}
This worked for me.
I found this on a Microsoft Support page http://support.microsoft.com/kb/2019698.
It works great! And since it came from Microsoft, I feel like it's pretty legit.
Basically there are two steps.
Schedule the backup from your task scheduler. You might want to put into a .bat or .cmd file first and then schedule that file.
sqlcmd -S YOUR_SERVER_NAME\SQLEXPRESS -E -Q "EXEC sp_BackupDatabases @backupLocation='C:\SQL_Backup\', @backupType='F'" 1>c:\SQL_Backup\backup.log
Obviously replace YOUR_SERVER_NAME with your computer name or optionally try .\SQLEXPRESS and make sure the backup folder exists. In this case it's trying to put it into c:\SQL_Backup
Excel is incredibly broken when dealing with CSVs. LibreOffice does a much better job. So, I found out that:
This is how I achieved the same in Scala. I am not sure if it is more efficient than the valid answer, but it requires less coding
val parquetFileDF = sqlContext.read.parquet("myParquetFule.parquet")
val myRow7th = parquetFileDF.rdd.take(7).last
You can use query parameters for filtering and path parameters for grouping. The following link has good info on this When to use pathParams or QueryParams
ORDER BY alters the order in which items are returned.
GROUP BY will aggregate records by the specified columns which allows you to perform aggregation functions on non-grouped columns (such as SUM, COUNT, AVG, etc).
display: inline-block;
max-width: 80%;
height: 1.5em;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
Just right click on a table and select "backup". The popup will show various options, including "Format", select "plain" and you get plain SQL.
pgAdmin is just using pg_dump to create the dump, also when you want plain SQL.
It uses something like this:
pg_dump --user user --password --format=plain --table=tablename --inserts --attribute-inserts etc.
MySQL says:
All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.
When do I use it ?
Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED
data type.
A common mistake is to use a primary key that is an auto-increment INT
starting at zero, yet the type is SIGNED
, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.
The simplest way to put an image into a button:
<button onclick="myFunction()"><img src="your image name here.png"></button>
This will automatically resize the button to the size of the image.
Unchecked the content type in Postman and postman automatically detect the content type based on your input in the run time.
$('#selector').delay(5000).fadeOut('slow');
The easiest way to do this is :
ALTER TABLE db.TABLENAME ADD COLUMN [datatype] NOT NULL DEFAULT 'value'
Ex : Adding a column x (bit datatype) to a table ABC with default value 0
ALTER TABLE db.ABC ADD COLUMN x bit NOT NULL DEFAULT 0
PS : I am not a big fan of using the table designer for this. Its so much easier being conventional / old fashioned sometimes. :). Hope this helps answer

Commonly all works as expected with one small difference. Login from Devices
config now moves to Products -> Facebook Login
.
So you need to:
App id
from headline,Client Token
from app Settings -> Advanced
. There is also Native or desktop app?
question/config. I turn it on.Add product
and then Get started
on Facebook login
. Move back to your app config, click to newly added Facebook login
and you'll see your Login from Devices

Option 1: Either include this in your JS file:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>
Option 2: or just use the URL to download 'angular-route.min.js' to your local.
and then (whatever option you choose) add this 'ngRoute' as dependency.
explained:
var app = angular.module('myapp', ['ngRoute']);

I couldn't get the 'require' error to go away by using any of the tricks above.
But I found out that the issue was that my TypeScript tools for Visual Studio where an old version (1.8.6.0) and the latest version as of today is (2.0.6.0).
You can download the latest version of the tools from:
You want the NPGSQL library. Your only other alternative is ODBC.
You should actually return "200 OK" and in the response body include a message about what happened with the posted data. Then it's up to your application to understand the message.
The thing is, HTTP status codes are exactly that - HTTP status codes. And those are meant to have meaning only at the transportation layer, not at the application layer. The application layer should really never even know that HTTP is being used. If you switched your transportation layer from HTTP to Homing Pigeons, it should not affect your application layer in any way.
Let me give you a non-virtual example. Let's say you fall in love with a girl and she loves you back but her family moves to a completely different country. She gives you her new snail-mail address. Naturally, you decide to send her a love letter. So you write your letter, put it into an envelope, write her address on the envelope, put a stamp on it and send it. Now let's consider these scenarios
In short: Returning "200 OK" doesn't mean that the server app has good news for you. It only means that it has some news.
PS: The 422 status code has a meaning only in the context of WebDAV. If you're not working with WebDAV, then 422 has exactly the same standard meaning as any other non-standard code = which is none.
you can Add contextual classes to every single row as follows:
<tr class="table-success"></tr>
<tr class="table-error"></tr>
<tr class="table-warning"></tr>
<tr class="table-info"></tr>
<tr class="table-danger"></tr>
You can also add them to table data same as above
You can set your table size by setting classes as table-sm and so on.
You can add custom classes and add your own styling:
<table class="table">
<thead style = "color:red;background-color:blue">
<tr>
<th></th>
<th>First Name</th>
<th>Last Name</th>
</tr>
</thead>
<tbody>
<tr>
<td>Asdf</td>
<td>qwerty</td>
</tr>
</tbody>
</table>
This way you can add custom styling. I have showed inline styling just for example how it works, you can add classes and call them in your css as well.
I did Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3
but it still did not work. Then looked in my project bin folder and saw that it still had the old System.Web.Mvc file.
So I manually copied the newer file from the package to the bin folder. Then I was up and running again.

In my case, I use Anaconda, so running the following command from conda terminal inside my environment solved it, and created this requirements txt file for me automatically:
conda list -e > requirements.txt
This was taken from this Github link pratos/condaenv.txt
If an error been seen, and you are using anaconda, try to use the .yml option:
conda env export > <environment-name>.yml
For other person to use the environment...Or if you are creating a new enviroment on other machine: conda env create -f .yml
Apart from an understanding of the accesses amongst modules and their respective packages. I believe the crux of it lies in the Module System#Relaxed-strong-encapsulation and I would just cherry-pick the relevant parts of it to try and answer the question.
What defines an illegal reflective access and what circumstances trigger the warning?
To aid in the migration to Java-9, the strong encapsulation of the modules could be relaxed.
An implementation may provide static access, i.e. by compiled bytecode.
May provide a means to invoke its run-time system with one or more packages of one or more of its modules open to code in all unnamed modules, i.e. to code on the classpath. If the run-time system is invoked in this way, and if by doing so some invocations of the reflection APIs succeed where otherwise they would have failed.
In such cases, you've actually ended up making a reflective access which is "illegal" since in a pure modular world you were not meant to do such accesses.
How it all hangs together and what triggers the warning in what scenario?
This relaxation of the encapsulation is controlled at runtime by a new launcher option --illegal-access
which by default in Java9 equals permit
. The permit
mode ensures
The first reflective-access operation to any such package causes a warning to be issued, but no warnings are issued after that point. This single warning describes how to enable further warnings. This warning cannot be suppressed.
The modes are configurable with values debug
(message as well as stacktrace for every such access), warn
(message for each such access), and deny
(disables such operations).
Few things to debug and fix on applications would be:-
--illegal-access=deny
to get to know about and avoid opening packages from one module to another without a module declaration including such a directive(opens
) or explicit use of --add-opens
VM arg.jdeps
tool with the --jdk-internals
optionThe warning message issued when an illegal reflective-access operation is detected has the following form:
WARNING: Illegal reflective access by $PERPETRATOR to $VICTIM
where:
$PERPETRATOR
is the fully-qualified name of the type containing the code that invoked the reflective operation in question plus the code source (i.e., JAR-file path), if available, and
$VICTIM
is a string that describes the member being accessed, including the fully-qualified name of the enclosing type
Questions for such a sample warning: = JDK9: An illegal reflective access operation has occurred. org.python.core.PySystemState
Last and an important note, while trying to ensure that you do not face such warnings and are future safe, all you need to do is ensure your modules are not making those illegal reflective accesses. :)
Your script could be stopping, not because of the PHP timeout but because of the timeout in the browser you're using to access the script (ie. Firefox, Chrome, etc). Unfortunately there's seldom an easy way to extend this timeout, and in most browsers you simply can't. An option you have here is to access the script over a terminal. For example, on Windows you would make sure the PHP executable is in your path variable and then I think you execute:
C:\path\to\script> php script.php
Or, if you're using the PHP CGI, I think it's:
C:\path\to\script> php-cgi script.php
Plus, you would also set ini_set('max_execution_time', 0);
in your script as others have mentioned. When running a PHP script this way, I'm pretty sure you can use buffer flushing to echo out the script's progress to the terminal periodically if you wish. The biggest issue I think with this method is there's really no way of stopping the script once it's started, other than stopping the entire PHP process or service.
System.currentTimeMillis()
does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date
instance to a string before using it. You can use DateFormat
s to convert Date
s to String
s in any timezone:
DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());
A static block executes once in the life cycle of any program, another property of static block is that it executes before the main method.
convert string to datetime object
from datetime import datetime
s = "2016-03-26T09:25:55.000Z"
f = "%Y-%m-%dT%H:%M:%S.%fZ"
out = datetime.strptime(s, f)
print(out)
output:
2016-03-26 09:25:55
First, you need to convert your string to NSDate with its format. Then, you change the dateFormatter
to your simple format and convert it back to a String.
Swift 3
let dateString = "Thu, 22 Oct 2015 07:45:17 +0000"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEE, dd MMM yyyy hh:mm:ss +zzzz"
dateFormatter.locale = Locale.init(identifier: "en_GB")
let dateObj = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "MM-dd-yyyy"
print("Dateobj: \(dateFormatter.string(from: dateObj!))")
The printed result is: Dateobj: 10-22-2015
import java.text.SimpleDateFormat;
import java.text.DateFormat;
import java.util.Date;
public class Main {
public static void main(String [] args){
try {
DateFormat parseFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm a");
String sDate = "22-01-2019 13:35 PM";
Date date = parseFormat.parse(sDate);
SimpleDateFormat displayFormat = new SimpleDateFormat("dd-MM-yyyy hh:mm a");
sDate = displayFormat.format(date);
System.out.println("The required format : " + sDate);
} catch (Exception e) {}
}
}
There are a few functions like:
NSStringFromCGPoint
NSStringFromCGSize
NSStringFromCGRect
NSStringFromCGAffineTransform
NSStringFromUIEdgeInsets
An example:
NSLog(@"rect1: %@", NSStringFromCGRect(rect1));
I guess it's just because the onblur event is called as a result of the input losing focus, there isn't a blur action associated with an input, like there is a click action associated with a button
None of the different solutions found in the many topics on the subject worked perfectly for my case (x dynamic multiline labels in dynamic table view cells) .
I found a way to do it :
After having set the constraints on your label and set its multiline property to 0, make a subclass of UILabel ; I called mine AutoLayoutLabel :
@implementation AutoLayoutLabel
- (void)layoutSubviews{
[self setNeedsUpdateConstraints];
[super layoutSubviews];
self.preferredMaxLayoutWidth = CGRectGetWidth(self.bounds);
}
@end
[Edit: The question originally asked how to get the mantissa and exponent.]
Where n is the number to get the real mantissa/exponent:
exponent = int(log(n))
mantissa = n / 10^exponent
Or, to get the answer you were looking for:
exponent = int(n)
mantissa = n - exponent
These are not Java exactly but should be easy to convert.
You cannot resize an array in java.
Once the size of array is declared, it remains fixed.
Instead you can use ArrayList
that has dynamic size, meaning you don't need to worry about its size. If your array list is not big enough to accommodate new values then it will be resized automatically.
ArrayList<String> ar = new ArrayList<String>();
String s1 ="Test1";
String s2 ="Test2";
String s3 ="Test3";
ar.add(s1);
ar.add(s2);
ar.add(s3);
String s4 ="Test4";
ar.add(s4);
I would do the following:
public class Book { private final String title; private final String isbn; public Book(final String t, final String i) { if(t == null) { throw new IllegalArgumentException("t cannot be null"); } if(i == null) { throw new IllegalArgumentException("i cannot be null"); } title = t; isbn = i; } }
I am making the assumption here that:
1) the title will never change (hence title is final) 2) the isbn will never change (hence isbn is final) 3) that it is not valid to have a book without both a title and an isbn.
Consider a Student class:
public class Student { private final StudentID id; private String firstName; private String lastName; public Student(final StudentID i, final String first, final String last) { if(i == null) { throw new IllegalArgumentException("i cannot be null"); } if(first == null) { throw new IllegalArgumentException("first cannot be null"); } if(last == null) { throw new IllegalArgumentException("last cannot be null"); } id = i; firstName = first; lastName = last; } }
There a Student must be created with an id, a first name, and a last name. The student ID can never change, but a persons last and first name can change (get married, changes name due to losing a bet, etc...).
When deciding what constrructors to have you really need to think about what makes sense to have. All to often people add set/get methods because they are taught to - but very often it is a bad idea.
Immutable classes are much better to have (that is classes with final variables) over mutable ones. This book: http://books.google.com/books?id=ZZOiqZQIbRMC&pg=PA97&sig=JgnunNhNb8MYDcx60Kq4IyHUC58#PPP1,M1 (Effective Java) has a good discussion on immutability. Look at items 12 and 13.
If you are running on headless CI and are installing the Android SDK through command line, make sure to include the m2repository packages in the --filter
argument:
android update sdk --no-ui --filter platform-tools,build-tools-19.0.1,android-19,extra-android-support,extra-android-m2repository,extra-google-m2repository
Update
As of Android SDK Manager rev. 22.6.4 this does not work anymore. Try this instead:
android list sdk --all
You will get a list of all available SDK packages. Look up the numerical values of the components from the first command above ("Google Repository" and others you might be missing).
Install the packages using their numerical values:
android update sdk --no-ui --all --filter <num>
Update #2 (Sept 2017)
With the "new" Android SDK tools that were released earlier this year, the android
command is now deprecated, and similar functionality has been moved to a new tool called sdkmanager
:
List installed components:
sdkmanager --list
Update installed components:
sdkmanager --update
Install a new component (e.g. build tools version 26.0.0
):
sdkmanager 'build-tools;26.0.0'

The problem with camel case is that there are often different interpretations of words - for example, checkinService vs checkInService. Going along with Aaron's answer, it is difficult with auto-completion if you have many similarly named repos to have to constantly check if the person who created the repo you care about used a certain breakdown of the upper and lower cases. avoid upper case.
His point about dashes is also well-advised.
@RequestParam is use for query parameter(static values) like: http://localhost:8080/calculation/pow?base=2&ext=4
@PathVariable is use for dynamic values like : http://localhost:8080/calculation/sqrt/8
@RequestMapping(value="/pow", method=RequestMethod.GET)
public int pow(@RequestParam(value="base") int base1, @RequestParam(value="ext") int ext1){
int pow = (int) Math.pow(base1, ext1);
return pow;
}
@RequestMapping("/sqrt/{num}")
public double sqrt(@PathVariable(value="num") int num1){
double sqrtnum=Math.sqrt(num1);
return sqrtnum;
}
In this context, "attribute" simply means a data member of an object.
I had to uninstall my anti virus! Before uninstalling I clicked on the option where it said to disable auto-protect for 15 min. I also clicked on another option that supposibly disabled the anti-virus. That still was blocking my server! I don't understand why Norton makes it so hard to literally stop doing everything it's doing. I know I could had solve it by adding an exception to the firewall but Norton was taking care of windows firewall as well.
Got my own answer: Using this function from the data from the textarea solves the problem:
function mynl2br($text) {
return strtr($text, array("\r\n" => '<br />', "\r" => '<br />', "\n" => '<br />'));
}

First let us understand Spring:
Spring is a lightweight and flexible framework.
Bean: is an object, which is created, managed and destroyed in Spring Container. We can inject an object into the Spring Container through the metadata(either xml or annotation), which is called inversion of control.
Analogy: Let us assume farmer is having a farmland cultivating by seeds(or beans). Here, Farmer is Spring Framework, Farmland land is Spring Container, Beans are Spring Beans, Cultivating is Spring Processors.
Like bean life-cycle, spring beans too having it's own life-cycle.
Following is sequence of a bean lifecycle in Spring:
Instantiate: First the spring container finds the bean’s definition from the XML file and instantiates the bean.
Populate properties: Using the dependency injection, spring populates all of the properties as specified in the bean definition.
Set Bean Name: If the bean implements BeanNameAware
interface, spring passes the bean’s id to setBeanName()
method.
Set Bean factory: If Bean implements BeanFactoryAware
interface, spring passes the beanfactory to setBeanFactory()
method.
Pre-Initialization: Also called post process of bean. If there are any bean BeanPostProcessors associated with the bean, Spring calls postProcesserBeforeInitialization()
method.
Initialize beans: If the bean implements IntializingBean
,its afterPropertySet()
method is called. If the bean has init method declaration, the specified initialization method is called.
Post-Initialization: – If there are any BeanPostProcessors
associated with the bean, their postProcessAfterInitialization()
methods will be called.
Ready to use: Now the bean is ready to use by the application
Destroy: If the bean implements DisposableBean
, it will call the destroy()
method
You can use something like this, passing the ListView you want in param
private void AutoSizeColumnList(ListView listView)
{
//Prevents flickering
listView.BeginUpdate();
Dictionary<int, int> columnSize = new Dictionary<int,int>();
//Auto size using header
listView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
//Grab column size based on header
foreach(ColumnHeader colHeader in listView.Columns )
columnSize.Add(colHeader.Index, colHeader.Width);
//Auto size using data
listView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);
//Grab comumn size based on data and set max width
foreach (ColumnHeader colHeader in listView.Columns)
{
int nColWidth;
if (columnSize.TryGetValue(colHeader.Index, out nColWidth))
colHeader.Width = Math.Max(nColWidth, colHeader.Width);
else
//Default to 50
colHeader.Width = Math.Max(50, colHeader.Width);
}
listView.EndUpdate();
}
The problem is the Python module requests
. It can be fixed by
$ sudo apt-get purge python-requests
[now requests and pip gets deinstalled]
$ sudo apt-get install python-requests python-pip
If you have this problem with Python 3, you have to write python3
instead of python
.
If you use Thymeleaf 3:
<script th:inline="javascript">
var username = [[${session.user.name}]];
</script>
The first question is what are your needs? UTF-8 encoding is a pretty good compromise between taking text created with a cheap editor and support for a wide variety of languages. In regards to the browser identifying the encoding, the response (from the web server) should tell the browser the encoding. Still most browsers will attempt to guess, because this is either missing or wrong in so many cases. They guess by reading some amount of the result stream to see if there is a character that does not fit in the default encoding. Currently all browser(? I did not check this, but it is pretty close to true) use utf-8 as the default.
So use utf-8 unless you have a compelling reason to use one of the many other encoding schemes.
Status 422 seems most appropiate based on the spec.
The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
They state that malformed xml is an example of bad syntax (calling for a 400). A malformed query string seems analogous to this, so 400 doesn't seem appropriate for a well-formed query-string which is missing a param.
UPDATE @DavidV correctly points out that this spec is for WebDAV, not core HTTP. But some popular non-WebDAV APIs are using 422 anyway, for lack of a better status code (see this).
I found that even though it worked on my dev box, the assembly wasn't added to the project. Search for Microsoft.Web.Infrastructure in NuGet and install it from there. Then, make sure it has Copy Local selected.
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).
For integers and with Python 3:
def divround_down(value, step):
return value//step*step
def divround_up(value, step):
return (value+step-1)//step*step
Producing:
>>> [divround_down(x,5) for x in range(20)]
[0, 0, 0, 0, 0, 5, 5, 5, 5, 5, 10, 10, 10, 10, 10, 15, 15, 15, 15, 15]
>>> [divround_up(x,5) for x in range(20)]
[0, 5, 5, 5, 5, 5, 10, 10, 10, 10, 10, 15, 15, 15, 15, 15, 20, 20, 20, 20]
Instead of
Scanner in = new Scanner(System.in);
String question;
question = in.next();
Type in
Scanner in = new Scanner(System.in);
String question;
question = in.nextLine();
This should be able to take spaces as input.
They're examples provided by the Android team, if you've already loaded Samples, you can import Home screen replacement sample by following these steps.
File > New > Other >Android > Android Sample Project > Android x.x > Home > Finish
But if you do not have samples loaded, then download it using the below steps
Windows > Android SDK Manager > chooses "Sample for SDK" for SDK you need it > Install package > Accept License > Install
Use this instead:
var divID = "question-" + (i+1)
It's a fairly common problem and doesn't just happen in JavaScript. The idea is that +
can represent both concatenation and addition.
Since the + operator will be handled left-to-right the decisions in your code look like this:
"question-" + i
: since "question-"
is a string, we'll do concatenation, resulting in "question-1"
"question-1" + 1
: since "queston-1"
is a string, we'll do concatenation, resulting in "question-11"
.With "question-" + (i+1)
it's different:
(i+1)
is in parenthesis, its value must be calculated before the first +
can be applied:
i
is numeric, 1
is numeric, so we'll do addition, resulting in 2
"question-" + 2
: since "question-"
is a string, we'll do concatenation, resulting in "question-2"
.First of all, all the reasons are subjective. It's more like a matter of taste rather than a reason.
Personally, I find heredoc quite useless and use it occasionally, most of the time when I need to get some HTML into a variable and don't want to bother with output buffering, to form an HTML email message for example.
Formatting doesn't fit general indentation rules, but I don't think it's a big deal.
//some code at it's proper level
$this->body = <<<HERE
heredoc text sticks to the left border
but it seems OK to me.
HERE;
$this->title = "Feedback";
//and so on
As for the examples in the accepted answer, it is merely cheating.
String examples, in fact, being more concise if one won't cheat on them
$sql = "SELECT * FROM $tablename
WHERE id in [$order_ids_list]
AND product_name = 'widgets'";
$x = 'The point of the "argument" was to illustrate the use of here documents';
It is just this:
int count = 4;
string sub = mystring.Substring(mystring.Length - count, count);
You can use the cat powershell command.
First create a simple text file with a few characters. The more initial chars you enter, the quicker it becomes larger. Let's call it out.txt. Then in Powershell:
cat out.txt >> out.txt
Wait as long as it's necessary to make the file big enough. Then hit ctrl-c to end it.
You should use a callback parameter:
function Typer(callback)
{
var srcText = 'EXAMPLE ';
var i = 0;
var result = srcText[i];
var interval = setInterval(function() {
if(i == srcText.length - 1) {
clearInterval(interval);
callback();
return;
}
i++;
result += srcText[i].replace("\n", "<br />");
$("#message").html(result);
},
100);
return true;
}
function playBGM () {
alert("Play BGM function");
$('#bgm').get(0).play();
}
Typer(function () {
playBGM();
});
// or one-liner: Typer(playBGM);
So, you pass a function as parameter (callback
) that will be called in that if
before return
.
Also, this is a good article about callbacks.

The following fixed this for me:
After this successfully completed, I no longer received the error, and I didn't have to close and reopen anything.
You have change proper version of the JAVA_HOME and PATH in environmental variables.
Pressing ESC quits from insert mode to normal mode, where you can press : to type in a command. Press i again to back to insert mode, and you are good to go.
I'm not a Vim guru, so someone else can be more experienced and give you other options.
r := strings(byteData)
This also works to turn []byte
into io.Reader
You may store the parameters for the blob detector in a file, but this is not necessary. Example:
// set up the parameters (check the defaults in opencv's code in blobdetector.cpp)
cv::SimpleBlobDetector::Params params;
params.minDistBetweenBlobs = 50.0f;
params.filterByInertia = false;
params.filterByConvexity = false;
params.filterByColor = false;
params.filterByCircularity = false;
params.filterByArea = true;
params.minArea = 20.0f;
params.maxArea = 500.0f;
// ... any other params you don't want default value
// set up and create the detector using the parameters
cv::SimpleBlobDetector blob_detector(params);
// or cv::Ptr<cv::SimpleBlobDetector> detector = cv::SimpleBlobDetector::create(params)
// detect!
vector<cv::KeyPoint> keypoints;
blob_detector.detect(image, keypoints);
// extract the x y coordinates of the keypoints:
for (int i=0; i<keypoints.size(); i++){
float X = keypoints[i].pt.x;
float Y = keypoints[i].pt.y;
}
For about 3 weeks, I faced the same problem.
After googling and trying and asking without solutions, I found that there was an Unknown Device called Android Composite ADB Interface in the Device Manager
.
I had a look on this and finally resolved it by downloading the ADB Driver from here. (Maybe you need to troubleshoot your PC but the installer will tell you this.)
I am not sure did you see this list of MS SQL Modules for Node JS
Share your experience after using one if possible .
Good Luck
Given points (X1,Y1) and (X2,Y2) then:
dX = X1 - X2;
dY = Y1 - Y2;
if (dX*dX + dY*dY > (5*5))
{
//your code
}
You can use %~dp0
to get the path of the currently running batch file.
Edited to change directory to the VBS location before running
If you want the VBS to synchronously run in the same window, then
@echo off
pushd %~dp0
cscript necdaily.vbs
If you want the VBS to synchronously run in a new window, then
@echo off
pushd %~dp0
start /wait "" cmd /c cscript necdaily.vbs
If you want the VBS to asynchronously run in the same window, then
@echo off
pushd %~dp0
start /b "" cscript necdaily.vbs
If you want the VBS to asynchronously run in a new window, then
@echo off
pushd %~dp0
start "" cmd /c cscript necdaily.vbs
In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.
import javafx.fxml.Initializable;
class MyController implements Initializable {
@FXML private TableView<MyModel> tableView;
@Override
public void initialize(URL location, ResourceBundle resources) {
tableView.getItems().addAll(getDataFromSource());
}
}
Parameters:
location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized.
And the note of the docs why the simple way of using @FXML public void initialize()
works:
NOTE
This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.
This can now be done without JS, just pure CSS. So, anyone trying to do this for modern browsers should look into using position: sticky
instead.
Currently, both Edge and Chrome have a bug where position: sticky
doesn't work on thead
or tr
elements, however it's possible to use it on th
elements, so all you need to do is just add this to your code:
th {
position: sticky;
top: 50px; /* 0px if you don't have a navbar, but something is required */
background: white;
}
Note: you'll need a background color for them, or you'll be able to see through the sticky title bar.
This has very good browser support.
Demo with your code (HTML unaltered, above 5 lines of CSS added, all JS removed):

For me when I created a file and saved it as python file, I was getting this error during importing. I had to create a filename with the type ".py" , like filename.py and then save it as a python file. post trying to import the file worked for me.
If you are using PHP >= 7.2 consider using inbuilt sodium core extension for encrption.
It is modern and more secure. You can find more information here - http://php.net/manual/en/intro.sodium.php. and here - https://paragonie.com/book/pecl-libsodium/read/00-intro.md
Example PHP 7.2 sodium encryption class -
<?php
/**
* Simple sodium crypto class for PHP >= 7.2
* @author MRK
*/
class crypto {
/**
*
* @return type
*/
static public function create_encryption_key() {
return base64_encode(sodium_crypto_secretbox_keygen());
}
/**
* Encrypt a message
*
* @param string $message - message to encrypt
* @param string $key - encryption key created using create_encryption_key()
* @return string
*/
static function encrypt($message, $key) {
$key_decoded = base64_decode($key);
$nonce = random_bytes(
SODIUM_CRYPTO_SECRETBOX_NONCEBYTES
);
$cipher = base64_encode(
$nonce .
sodium_crypto_secretbox(
$message, $nonce, $key_decoded
)
);
sodium_memzero($message);
sodium_memzero($key_decoded);
return $cipher;
}
/**
* Decrypt a message
* @param string $encrypted - message encrypted with safeEncrypt()
* @param string $key - key used for encryption
* @return string
*/
static function decrypt($encrypted, $key) {
$decoded = base64_decode($encrypted);
$key_decoded = base64_decode($key);
if ($decoded === false) {
throw new Exception('Decryption error : the encoding failed');
}
if (mb_strlen($decoded, '8bit') < (SODIUM_CRYPTO_SECRETBOX_NONCEBYTES + SODIUM_CRYPTO_SECRETBOX_MACBYTES)) {
throw new Exception('Decryption error : the message was truncated');
}
$nonce = mb_substr($decoded, 0, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
$ciphertext = mb_substr($decoded, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');
$plain = sodium_crypto_secretbox_open(
$ciphertext, $nonce, $key_decoded
);
if ($plain === false) {
throw new Exception('Decryption error : the message was tampered with in transit');
}
sodium_memzero($ciphertext);
sodium_memzero($key_decoded);
return $plain;
}
}
Sample Usage -
<?php
$key = crypto::create_encryption_key();
$string = 'Sri Lanka is a beautiful country !';
echo $enc = crypto::encrypt($string, $key);
echo crypto::decrypt($enc, $key);
Support for the extended ternary operator was added in Twig 1.12.0.
If foo
echo yes
else echo no
:
{{ foo ? 'yes' : 'no' }}
If foo
echo it, else echo no
:
{{ foo ?: 'no' }}
or
{{ foo ? foo : 'no' }}
If foo
echo yes
else echo nothing:
{{ foo ? 'yes' }}
or
{{ foo ? 'yes' : '' }}
Returns the value of foo
if it is defined and not null, no
otherwise:
{{ foo ?? 'no' }}
Returns the value of foo
if it is defined (empty values also count), no
otherwise:
{{ foo|default('no') }}
const a = {
foods: {
dinner: 'Pasta'
}
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta
Using JSON.stringify
and JSON.parse
is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.
Step 1, change your database's default charset:
ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
if the db is not created yet, create it with correct encodings:
CREATE DATABASE database_name DEFAULT CHARSET = utf8mb4 DEFAULT COLLATE = utf8mb4_unicode_ci;
Step 2, set charset when creating table:
CREATE TABLE IF NOT EXISTS table_name (
...
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci;
or alter table
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
ALTER TABLE table_name MODIFY field_name TEXT CHARSET utf8mb4;
In VB its normally Dir
to find the directory of the file. If it's not blank then it exists and then use Kill
to get rid of the file.
test = Dir(Filename)
If Not test = "" Then
Kill (Filename)
End If
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));

do you want to write code for that or just use command-line feature 'command redirection' as follows:
app.exe >> output.txt
as demonstrated here: http://discomoose.org/2006/05/01/output-redirection-to-a-file-from-the-windows-command-line/ (Archived at archive.org)
EDIT: link dead, here's another example: http://pcsupport.about.com/od/commandlinereference/a/redirect-command-output-to-file.htm
and
/or
are for control flow.
Ruby will not allow this as valid syntax:
false || raise "Error"
However this is valid:
false or raise "Error"
You can make the first work, with ()
but using or
is the correct method.
false || (raise "Error")
You can browse all the jQuery plugins tagged with "cookie" here:
http://plugins.jquery.com/plugin-tags/cookies
Plenty of options there.
Check out the one called jQuery Storage, which takes advantage of HTML5's localStorage. If localStorage isn't available, it defaults to cookies. However, it doesn't allow you to set expiration.
I'm using macOS Sierra (v10.12.1) Xcode v8.1 Swift 3.0.1 and here's what worked for me in ViewController.swift:

@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
// Your webView code goes here
let url = URL(string: "https://www.google.com")
if UIApplication.shared.canOpenURL(url!) {
UIApplication.shared.open(url!, options: [:], completionHandler: nil)
//If you want handle the completion block than
UIApplication.shared.open(url!, options: [:], completionHandler: { (success) in
print("Open url : \(success)")
})
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
};
I had a similar problem with crypto updates. A kludgy hack that gets around this is to include a '+ now() - now()' stunt at the end of the cell formula, with the setting as above to recalculate every minute. This worked for my price updates, but, definitely an ugly hack.
Use \1
instead of $1
.
\number Matches the contents of the group of the same number.

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:
Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"
You have to follow the following sequence of opeartions:
Map
to MapSet
with map.entrySet();
Mapset.iterator();
Map.Entry
with iterator.next();
Entry.getKey()
and Entry.getValue()
# define Map
for (Map.Entry entry: map.entrySet)
System.out.println(entry.getKey() + entry.getValue);
Simple example to achieve the below:
ApplicationDbContext forumDB = new ApplicationDbContext();
MonitorDbContext monitor = new MonitorDbContext();
Just scope the properties in the main context: (used to create and maintain the DB) Note: Just use protected: (Entity is not exposed here)
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("QAForum", throwIfV1Schema: false)
{
}
protected DbSet<Diagnostic> Diagnostics { get; set; }
public DbSet<Forum> Forums { get; set; }
public DbSet<Post> Posts { get; set; }
public DbSet<Thread> Threads { get; set; }
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
}
}
MonitorContext: Expose separate Entity here
public class MonitorDbContext: DbContext
{
public MonitorDbContext()
: base("QAForum")
{
}
public DbSet<Diagnostic> Diagnostics { get; set; }
// add more here
}
Diagnostics Model:
public class Diagnostic
{
[Key]
public Guid DiagnosticID { get; set; }
public string ApplicationName { get; set; }
public DateTime DiagnosticTime { get; set; }
public string Data { get; set; }
}
If you like you could mark all entities as protected inside the main ApplicationDbContext, then create additional contexts as needed for each separation of schemas.
They all use the same connection string, however they use separate connections, so do not cross transactions and be aware of locking issues. Generally your designing separation so this shouldn't happen anyway.
A quick Google search got this (from http://www.codecodex.com/wiki/index.php?title=Count_the_number_of_occurrences_of_a_specific_character_in_a_string#JavaScript)
String.prototype.count=function(s1) {
return (this.length - this.replace(new RegExp(s1,"g"), '').length) / s1.length;
}
Use it like this:
test = 'one,two,three,four'
commas = test.count(',') // returns 3
You are making an ajax request which is asynchronous therefore your console log of the list length occurs before the ajax request has completed.
The only way of achieving what you want is changing the ajax call to be synchronous. You can do this by using the .ajax and passing in asynch : false however this is not recommended as it locks the UI up until the call has returned, if it fails to return the user has to crash out of the browser.
You can convert it with JS:
$('.image-class').each(function(){
var processing = $(this).attr('src');
$(this).parent().css({'background-image':'url('+processing+')'});
$(this).hide();
});
If you were dealing with, given two ranges [x1:x2]
and [y1:y2]
, natural / anti-natural order ranges at the same time where:
x1 <= x2 && y1 <= y2
or x1 >= x2 && y1 >= y2
then you may want to use this to check:
they are overlapped <=> (y2 - x1) * (x2 - y1) >= 0
where only four operations are involved:
In base R a formula interface with interactions (:
) can be used to achieve this.
df <- read.csv("~/Desktop/TestData.csv")
df <- data.frame(stack(df[,-1]), Label=df$Label) # reshape to long format
boxplot(values ~ Label:ind, data=df, col=c("red", "limegreen"), las=2)
You can use the Java Geodesy Library for GPS, it uses the Vincenty's formulae which takes account of the earths surface curvature.
Implementation goes like this:
import org.gavaghan.geodesy.*;
...
GeodeticCalculator geoCalc = new GeodeticCalculator();
Ellipsoid reference = Ellipsoid.WGS84;
GlobalPosition pointA = new GlobalPosition(latitude, longitude, 0.0); // Point A
GlobalPosition userPos = new GlobalPosition(userLat, userLon, 0.0); // Point B
double distance = geoCalc.calculateGeodeticCurve(reference, userPos, pointA).getEllipsoidalDistance(); // Distance between Point A and Point B
The resulting distance is in meters.
AttributeError is raised when attribute of the object is not available.
An attribute reference is a primary followed by a period and a name:
attributeref ::= primary "." identifier
To return a list of valid attributes for that object, use dir()
, e.g.:
dir(scipy)
So probably you need to do simply: import scipy.sparse
The same query is written as below for psql command prompt of postgres.
D:\TOOLS\Postgresql-9.4.1-3\bin>psql -U postgres -d DatabaseName -h localhost - t -c "Select u.\"UserName\" from users u Where u.\"UserId\"=1;
Use import test1
for the 1st use - it will execute the script. For later invocations, treat the script as an imported module, and call the reload(test1)
method.
When
reload(module)
is executed:
- Python modules’ code is recompiled and the module-level code reexecuted, defining a new set of objects which are bound to names in the module’s dictionary. The init function of extension modules is not called
A simple check of sys.modules
can be used to invoke the appropriate action. To keep referring to the script name as a string ('test1'
), use the 'import()' builtin.
import sys
if sys.modules.has_key['test1']:
reload(sys.modules['test1'])
else:
__import__('test1')
On the other hand, it:
At the cost of:
So really it depends on what you're doing, but I tend to prefer a DataReader until I need something that's only supported by a dataset. SqlDataReader is perfect for the common data access case of binding to a read-only grid.

You are opening the csv file in binary mode, it should be 'w'
import csv
# open csv file in write mode with utf-8 encoding
with open('output.csv','w',encoding='utf-8',newline='')as w:
fieldnames = ["SNo", "States", "Dist", "Population"]
writer = csv.DictWriter(w, fieldnames=fieldnames)
# write list of dicts
writer.writerows(list_of_dicts) #writerow(dict) if write one row at time
