After few years, I moved to leaflet map and I have fixed this issue completely, the following could be applied to google maps too:
var headerHeight = $("#navMap").outerHeight();
var footerHeight = $("footer").outerHeight();
var windowHeight = window.innerHeight;
var mapContainerHeight = headerHeight + footerHeight;
var totalMapHeight = windowHeight - mapContainerHeight;
$("#map").css("margin-top", headerHeight);
$("#map").height(totalMapHeight);
$(window).resize(function(){
var headerHeight = $("#navMap").outerHeight();
var footerHeight = $("footer").outerHeight();
var windowHeight = window.innerHeight;
var mapContainerHeight = headerHeight + footerHeight;
var totalMapHeight = windowHeight - mapContainerHeight;
$("#map").css("margin-top", headerHeight);
$("#map").height(totalMapHeight);
map.fitBounds(group1.getBounds());
});
How is this possible? Without an index on the er101_upd_date_iso column how can a clustered index scan be used?
An index is a B-Tree where each leaf node is pointing to a 'bunch of rows'(called a 'Page' in SQL internal terminology), That is when the index is a non-clustered index.
Clustered index is a special case, in which the leaf nodes has the 'bunch of rows' (rather than pointing to them). that is why...
1) There can be only one clustered index on the table.
this also means the whole table is stored as the clustered index, that is why you started seeing index scan rather than a table scan.
2) An operation that utilizes clustered index is generally faster than a non-clustered index

For the problem you have, you should really consider adding this column to a index, as you said adding a new index (or a column to an existing index) increases INSERT/UPDATE costs. But it might be possible to remove some underutilized index (or a column from an existing index) to replace with 'er101_upd_date_iso'.
If index changes are not possible, i recommend adding a statistics on the column, it can fasten things up when the columns have some correlation with indexed columns
http://msdn.microsoft.com/en-us/library/ms188038.aspx
BTW, You will get much more help if you can post the table schema of ER101_ACCT_ORDER_DTL. and the existing indices too..., probably the query could be re-written to use some of them.
We faced the same problem:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error error opening file /fs01/app/rms01/external/logs/SH_EXT_TAB_VGAG_DELIV_SCHED.log
In our case we had a RAC with 2 nodes. After giving write permission on the log directory, on both sides, everything worked fine.
It's an inlined image (png), encoded in base64. It can make a page faster: the browser doesn't have to query the server for the image data separately, saving a round trip.
(It can also make it slower if abused: these resources are not cached, so the bytes are included in each page load.)
I encountered this issue due to mismatch between the runtime versions of the assemblies. Please verify the runtime versions of the main assembly (calling application) and the referred assembly
REPLACE(REPLACE(a.CUST_ADDRESS1,CHR(10),' '),CHR(13),' ') as ADDRESS
Assuming this example HTML:
<input type="text" name="email" id="email" />
<input type="text" name="first_name" id="first_name" />
<input type="text" name="last_name" id="last_name" />
You could have this javascript:
$("#email").bind("change", function(e){
$.getJSON("http://yourwebsite.com/lokup.php?email=" + $("#email").val(),
function(data){
$.each(data, function(i,item){
if (item.field == "first_name") {
$("#first_name").val(item.value);
} else if (item.field == "last_name") {
$("#last_name").val(item.value);
}
});
});
});
Then just you have a PHP script (in this case lookup.php) that takes an email in the query string and returns a JSON formatted array back with the values you want to access. This is the part that actually hits the database to look up the values:
<?php
//look up the record based on email and get the firstname and lastname
...
//build the JSON array for return
$json = array(array('field' => 'first_name',
'value' => $firstName),
array('field' => 'last_name',
'value' => $last_name));
echo json_encode($json );
?>
You'll want to do other things like sanitize the email input, etc, but should get you going in the right direction.
What worked for me was excluding the hamcrest group from the junit test compile.
Here is the code from my build.gradle:
testCompile ('junit:junit:4.11') {

Check if the Console is telling you something. Usually this happen when the project could not be install in the device, and just show the previous one. The most common case I has seen this is when there are different signatures in the project, and is not running at all. Please, read all red letter you see. If the LogCat does not show anything, take for sure that the Console will do.
You can change action bar color on this way:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">@color/green_action_bar</item>
</style>
Thats all you need for changing action bar color.
Plus if you want to change the status bar color just add the line:
<item name="android:colorPrimaryDark">@color/green_dark_action_bar</item>
Here is a screenshot taken from developer android site to make it more clear, and here is a link to read more about customizing the color palete
Three libraries for accessing and manipulating dates and times, namely datetime, arrow and pendulum, all make these items available in namedtuples whose elements are accessible either by name or index. Moreover, the items are accessible in precisely the same way. (I suppose if I were more intelligent I wouldn't be surprised.)
>>> YEARS, MONTHS, DAYS, HOURS, MINUTES = range(5)
>>> import datetime
>>> import arrow
>>> import pendulum
>>> [datetime.datetime.now().timetuple()[i] for i in [YEARS, MONTHS, DAYS, HOURS, MINUTES]]
[2017, 6, 16, 19, 15]
>>> [arrow.now().timetuple()[i] for i in [YEARS, MONTHS, DAYS, HOURS, MINUTES]]
[2017, 6, 16, 19, 15]
>>> [pendulum.now().timetuple()[i] for i in [YEARS, MONTHS, DAYS, HOURS, MINUTES]]
[2017, 6, 16, 19, 16]
I normally do this in VB and its easier because Excel records macros in VB. So I normally go to Excel and save the macro I want to do.
So that's what I did now and I got this code:
Columns("E:E").ColumnWidth = 17.29;
Range("E3").Interior.Pattern = xlSolid;
Range("E3").Interior.PatternColorIndex = xlAutomatic;
Range("E3").Interior.Color = 65535;
Range("E3").Interior.TintAndShade = 0;
Range("E3").Interior.PatternTintAndShade = 0;
I think you can do something like this:
xlWorkSheet.Columns[5].ColumnWidth = 18;
For your last question what you need to do is loop trough the columns you want to set their width:
for (int i = 1; i <= 10; i++) // this will apply it from col 1 to 10
{
xlWorkSheet.Columns[i].ColumnWidth = 18;
}
Ruby 2.4 introduced the method Hash#transform_values!
, which you could use.
{ :a=>'a' , :b=>'b' }.transform_values! { |v| "%#{v}%" }
# => {:a=>"%a%", :b=>"%b%"}
I posted that in jQuery forums (I hope it can help):
Diving into the jQM code i've found this solution. I hope it can help other people:
To refresh a dynamically modified page:
function refreshPage(page){
// Page refresh
page.trigger('pagecreate');
page.listview('refresh');
}
It works even if you create new headers, navbars or footers. I've tested it with jQM 1.0.1.
CURL is the simplest way to go. Here is a simple call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "THE URL TO THE SERVICE");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, POST DATA);
$result = curl_exec($ch);
print_r($result);
curl_close($ch);
collect(Collectors.toList());
This is the call which you can use to convert any Stream to List.
more concretely:
List<String> myList = stream.collect(Collectors.toList());

https://www.geeksforgeeks.org/collectors-tolist-method-in-java-with-examples/
A key can be a function that returns a tuple:
s = sorted(s, key = lambda x: (x[1], x[2]))
Or you can achieve the same using itemgetter
(which is faster and avoids a Python function call):
import operator
s = sorted(s, key = operator.itemgetter(1, 2))
And notice that here you can use sort
instead of using sorted
and then reassigning:
s.sort(key = operator.itemgetter(1, 2))
I have used this and it seems to work with outlook, not using html but you can format the text with line breaks at least when the body is added as output.

I've used Francesco Balena's HashTable class several times in the past when a Collection or Dictionary wasn't a perfect fit and i just needed a HashTable.
simply use
final String WELCOME_MESSAGE = "Hello, welcome to the server";
the main part of this instruction is the 'final' keyword.

Tweak however you'd like!
Take a look at this answer: ImportError: no module named win32api
You can use
pip install pypiwin32
A way that I have done this is as follows:
At the python shell:
>>> from cryptography.fernet import Fernet
>>> key = Fernet.generate_key()
>>> print(key)
b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
>>> cipher = Fernet(key)
>>> password = "thepassword".encode('utf-8')
>>> token = cipher.encrypt(password)
>>> print(token)
b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='
Then, create a module with the following code:
from cryptography.fernet import Fernet
# you store the key and the token
key = b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
token = b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='
# create a cipher and decrypt when you need your password
cipher = Fernet(key)
mypassword = cipher.decrypt(token).decode('utf-8')
Once you've done this, you can either import mypassword directly or you can import the token and cipher to decrypt as needed.
Obviously, there are some shortcomings to this approach. If someone has both the token and the key (as they would if they have the script), they can decrypt easily. However it does obfuscate, and if you compile the code (with something like Nuitka) at least your password won't appear as plain text in a hex editor.
I know this question is over 6 years old, but still, I would like to share my method using tables and this won't require any CSS.

A semaphore is a counting synchronization mechanism, a mutex isn't.
Netbeans allows you to do a simple filecopy. As you know, Eclipse doesn't work like that. You must explicitly "import" files and projects.
If you do import, and if there are no problems, then they should show up.
I'd consider:
a) making a backup of your existing workspace
b) deleting and reinstalling Eclipse
c) Trying another "test import"
With eval("my script here")
function.
You can simplify this code to:
DirectorySearcher searcher = new DirectorySearcher();
searcher.Filter = "(&(objectCategory=user)(cn=steve.evans))";
SearchResultCollection results = searcher.FindAll();
if (results.Count == 1)
{
//do what you want to do
}
else if (results.Count == 0)
{
//user does not exist
}
else
{
//found more than one user
//something is wrong
}
If you can narrow down where the user is you can set searcher.SearchRoot to a specific OU that you know the user is under.
You should also use objectCategory instead of objectClass since objectCategory is indexed by default.
You should also consider searching on an attribute other than CN. For example it might make more sense to search on the username (sAMAccountName) since it's guaranteed to be unique.
You can use is_null() function.

while ($qValues=mysql_fetch_assoc($qResult))
if (is_null($qValues["foo"]))
echo "No foo data!";
else
echo "Foo data=".$qValues["foo"];

let value = query[key];
if(value){
obj[key] = value
} else {
delete obj[key]
}
})
this.$router.replace({
...this.$router.currentRoute,
query: obj
})
},
removeQuery(queryNameArray){
let obj = {}
queryNameArray.forEach(key => {
obj[key] = null
})
this.setQuery(obj)

I believe that I have the simplest answer yet using Spring Boot 1.4, included imports for the test class.:
public class SomeClass { /// this goes in it's own file
//// fields go here
}
import org.junit.Before
import org.junit.Test
import org.junit.runner.RunWith
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest
import org.springframework.http.MediaType
import org.springframework.test.context.junit4.SpringRunner
import org.springframework.test.web.servlet.MockMvc
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status
@RunWith(SpringRunner.class)
@WebMvcTest(SomeController.class)
public class ControllerTest {
@Autowired private MockMvc mvc;
@Autowired private ObjectMapper mapper;
private SomeClass someClass; //this could be Autowired
//, initialized in the test method
//, or created in setup block
@Before
public void setup() {
someClass = new SomeClass();
}
@Test
public void postTest() {
String json = mapper.writeValueAsString(someClass);
mvc.perform(post("/someControllerUrl")
.contentType(MediaType.APPLICATION_JSON)
.content(json)
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk());
}
}
If someone is interested, it is also possible to create an event source manually by adding some registry values.
Save the following lines as a .reg file, then import it to registry by double clicking it:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application\YOUR_EVENT_SOURCE_NAME_GOES_HERE]
"EventMessageFile"="C:\\Windows\\Microsoft.NET\\Framework64\\v4.0.30319\\EventLogMessages.dll"
"TypesSupported"=dword:00000007
This creates an event source named YOUR_EVENT_SOURCE_NAME_GOES_HERE
.
In Oracle 12c you can use the function STANDARD_HASH. It does not require any additional privileges.
select standard_hash('foo', 'MD5') from dual;
The dbms_obfuscation_toolkit is deprecated (see Note here). You can use DBMS_CRYPTO directly:
select rawtohex(
DBMS_CRYPTO.Hash (
UTL_I18N.STRING_TO_RAW ('foo', 'AL32UTF8'),
2)
) from dual;
Output:
ACBD18DB4CC2F85CEDEF654FCCC4A4D8
Add a lower function call if needed. More on DBMS_CRYPTO.
If you want to be able to add the styled text in xml you can create a custom view extending TextView and override setText():
public class HTMLStyledTextView extends TextView
{
public HTMLStyledTextView(Context context) {
super(context);
}
public HTMLStyledTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public HTMLStyledTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public void setText(CharSequence text, BufferType type)
{
super.setText(Html.fromHtml(text.toString()), type);
}
}
Then, you can use it like this (replace PACKAGE_NAME
with your package name):
<PACKAGE_NAME.HTMLStyledTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="<![CDATA[
<b>Bolded Text:</b> Non-Bolded Text
]]>"
/>
// 2. Select a database to use
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
die("Database selection failed: " . mysqli_error($connection));
}
You got the order of the arguments to mysqli_select_db()
backwards. And mysqli_error()
requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.
Note also that with mysqli you can specify the DB in mysqli_connect()
:
$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
die("Database connection failed: " . mysqli_connect_error();
}
You must use mysqli_connect_error()
, not mysqli_error()
, to get the error from mysqli_connect()
, since the latter requires you to supply a valid connection.
Simply saying, any() does this work : according to the condition even if it encounters one fulfilling value in the list, it returns true, else it returns false.
list = [2,-3,-4,5,6]
a = any(x>0 for x in lst)
print a:
True
list = [2,3,4,5,6,7]
a = any(x<0 for x in lst)
print a:
False
You can define a Multi-module project structure, then you can set the configuration for sonar in one properties file in the root folder of your project, (Way #1
)
I used this to access the ID in my component:
<Route path="/details/:id" component={DetailsPage}/>
And in the detail component:
export default class DetailsPage extends Component {
render() {
return(
<div>
<h2>{this.props.match.params.id}</h2>
</div>
)
}
}
This will render any ID inside an h2, hope that helps someone.
.phtml
was the standard file extension for PHP 2 programs. .php3
took over for PHP 3. When PHP 4 came out they switched to a straight .php
.
The older file extensions are still sometimes used, but aren't so common.
First step is to load your xml string into an XmlDocument, using powershell's unique ability to cast strings to [xml]
$doc = [xml]@'
<xml>
<Section name="BackendStatus">
<BEName BE="crust" Status="1" />
<BEName BE="pizza" Status="1" />
<BEName BE="pie" Status="1" />
<BEName BE="bread" Status="1" />
<BEName BE="Kulcha" Status="1" />
<BEName BE="kulfi" Status="1" />
<BEName BE="cheese" Status="1" />
</Section>
</xml>
'@
Powershell makes it really easy to parse xml with the dot notation. This statement will produce a sequence of XmlElements for your BEName elements:
$doc.xml.Section.BEName
Then you can pipe these objects into the where-object cmdlet to filter down the results. You can use ? as a shortcut for where
$doc.xml.Section.BEName | ? { $_.Status -eq 1 }
The expression inside the braces will be evaluated for each XmlElement in the pipeline, and only those that have a Status of 1 will be returned. The $_ operator refers to the current object in the pipeline (an XmlElement).
If you need to do something for every object in your pipeline, you can pipe the objects into the foreach-object cmdlet, which executes a block for every object in the pipeline. % is a shortcut for foreach:
$doc.xml.Section.BEName | ? { $_.Status -eq 1 } | % { $_.BE + " is delicious" }
Powershell is great at this stuff. It's really easy to assemble pipelines of objects, filter pipelines, and do operations on each object in the pipeline.
If BranchA has not been pushed to a remote then you can reorder the commits using rebase
and then simply merge
. It's preferable to use merge
over rebase
when possible because it doesn't create duplicate commits.
git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

// I think this is beter for all browsers...
No, an alt
attribute (it would be an attribute, not a tag) is not allowed for an a
element in any HTML specification or draft. And it does not seem to be recognized by any browser either as having any significance.
It’s a bit mystery why people try to use it, then, but the probable explanation is that they are doing so in analog with alt
attribute for img
elements, expecting to see a “tooltip” on mouseover. There are two things wrong with this. First, each element has attributes of its own, defined in the specs for each element. Second, the “tooltip” rendering of alt
attributes in some ancient browsers is/was a quirk or even a bug, rather than something to be expected; the alt
attribute is supposed to be presented to the user if and only if the image itself is not presented, for whatever reason.
To create a “tooltip”, use the title
attribute instead or, much better, Google for "CSS tooltips" and use CSS-based tooltips of your preference (they can be characterized as hidden “layers” that become visible on mouseover).
If you'd like to avoid hard-coding a specific design with css, but rather rely on the browser's default button, you can use the following css.
a.button {
-webkit-appearance: button;
-moz-appearance: button;
appearance: button;
}
Notice that it probably won't work on IE.
This pulls back client info as well.
var get = function(u){
var x = new XMLHttpRequest;
x.open('GET', u, false);
x.send();
return x.responseText;
}
JSON.parse(get('http://ifconfig.me/all.json'))
The dollar sign is treated just like a normal letter or underscore (_
). It has no special significance to the interpreter.
Unlike many similar languages, identifiers (such as functional and variable names) in Javascript can contain not only letters, numbers and underscores, but can also contain dollar signs. They are even allowed to start with a dollar sign, or consist only of a dollar sign and nothing else.
Thus, $
is a valid function or variable name in Javascript.
Why would you want a dollar sign in an identifier?
The syntax doesn't really enforce any particular usage of the dollar sign in an identifier, so it's up to you how you wish to use it. In the past, it has often been recommended to start an identifier with a dollar sign only in generated code - that is, code created not by hand but by a code generator.
In your example, however, this doesn't appear to be the case. It looks like someone just put a dollar sign at the start for fun - perhaps they were a PHP programmer who did it out of habit, or something. In PHP, all variable names must have a dollar sign in front of them.
There is another common meaning for a dollar sign in an interpreter nowadays: the jQuery object, whose name only consists of a single dollar sign ($
). This is a convention borrowed from earlier Javascript frameworks like Prototype, and if jQuery is used with other such frameworks, there will be a name clash because they will both use the name $
(jQuery can be configured to use a different name for its global object). There is nothing special in Javascript that allows jQuery to use the single dollar sign as its object name; as mentioned above, it's simply just another valid identifier name.
Attach a String() string
method to any named type and enjoy any custom "ToString" functionality:
package main
import "fmt"
type bin int
func (b bin) String() string {
return fmt.Sprintf("%b", b)
}
func main() {
fmt.Println(bin(42))
}
Playground: http://play.golang.org/p/Azql7_pDAA
Output

Another possibility is that one of the other scripts your including is causing the problem by also including JQuery or conflicting with $. Try removing your other included scripts and see if it fixes the issue. In my case, after hours of needlessly searching my one code, I removed scripts in a binary search pattern and discovered the offending script right away.
Connect with SSH and follow these instructions to install Node on a shared hosting
In short you first install NVM, then you install the Node version of your choice with NVM.
wget -qO- https://cdn.rawgit.com/creationix/nvm/master/install.sh | bash
Your restart your shell (close and reopen your sessions). Then you
nvm install stable
to install the latest stable version for example. You can install any version of your choice. Check node --version
for the node version you are currently using and nvm list
to see what you've installed.
In bonus you can switch version very easily (nvm use <version>
)
There's no need of PHP or whichever tricky workaround if you have SSH.
Sine you've mentioned you're using Eclipse... Eclipse can create the JARs for you, so long as you've run each class that has a main once. Right-click the project and click Export, then select "Runnable JAR file" under the Java folder. Select the class name in the launch configuration, choose a place to save the jar, and make a decision how to handle libraries if necessary. Click finish, wipe hands on pants.
It makes a duplicate copy of the string passed in by running a malloc and strcpy of the string passed in. The malloc'ed buffer is returned to the caller, hence the need to run free on the return value.
Just write in your Custom ArrayAdaper
this code:

this.customListviewList.addAll(events);
notifyDataSetChanged();
}
I think this will do it for you:

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree
option for single commands, or the GIT_WORK_TREE
environment variable. There is also the core.worktree
configuration option but it will not work in a bare repository (check the man page for what it does).
# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status
'Create a class to hold the pair...
Public Class ColumnValue
Public ColumnName As String
Public ColumnValue As New Object
End Class
'Build the pair...

For Each item As DataColumn In row.Table.Columns
Dim rowValue As New ColumnValue
rowValue.ColumnName = item.Caption
rowValue.ColumnValue = row.item(item.Ordinal)
RowValues.Add(rowValue)
rowValue = Nothing
Next
' Now you can grab the value by the column name...
Dim results = (From p In RowValues Where p.ColumnName = "MyColumn" Select p.ColumnValue).FirstOrDefault

There are additional base64 specs. (See the table here for specifics ). But essentially you need 65 chars to encode: 26 lowercase + 26 uppercase + 10 digits = 62.
You need two more ['+', '/'] and a padding char '='. But none of them are url friendly, so just use different chars for them and you're set. The standard ones from the chart above are ['-', '_'], but you could use other chars as long as you decoded them the same, and didn't need to share with others.
I'd recommend just writing your own helpers. Like these from the comments on the php manual page for base64_encode:
function base64_url_encode($input) {
return strtr(base64_encode($input), '+/=', '._-');
}
function base64_url_decode($input) {
return base64_decode(strtr($input, '._-', '+/='));
}
Similar answer to Gunnar, with more complete example: You can even transparently return the whole thing:
function dumpArguments(...args) {
for (var i = 0; i < args.length; i++)
console.log(args[i]);
return args;
}
dumpArguments("foo", "bar", true, 42, ["yes", "no"], { 'banana': true });
Output:
foo
bar
true
42
["yes","no"]
{"banana":true}

As per 'dtb' you need to use HttpStatusCode, but following 'zeldi' you need to be extra careful with code responses >= 400.
This has worked for me:
HttpWebResponse response = null;
HttpStatusCode statusCode;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException we)
{
response = (HttpWebResponse)we.Response;
}
statusCode = response.StatusCode;
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
sResponse = reader.ReadToEnd();
Console.WriteLine(sResponse);
Console.WriteLine("Response Code: " + (int)statusCode + " - " + statusCode.ToString());
Best practice:
compile 'com.android.support:design:25.0.1'

A regular pull is fetch + merge, but what you want is fetch + rebase. This is an option with the pull
command:
git pull --rebase
A simplier option is to just capture the digits and replace them.
const name = 'preceding_text_0_following_text';_x000D_
const matcher = /(\d+)/;_x000D_
_x000D_
// Replace with whatever you would like_x000D_
const newName = name.replace(matcher, 'NEW_STUFF');_x000D_
console.log("Full replace", newName);_x000D_
_x000D_
// Perform work on the match and replace using a function_x000D_
// In this case increment it using an arrow function_x000D_
const incrementedName = name.replace(matcher, (match) => ++match);_x000D_
console.log("Increment", incrementedName);
_x000D_
session_start();
echo session_id();
In CSS you need to use a Unicode escape sequence in place of HTML Entities. This is based on the hexadecimal value of a character.
I found that the easiest way to convert symbol to their hexadecimal equivalent is, such as from ▾ (▾
) to \25BE
is to use the Microsoft calculator =)
Yes. Enable programmers mode, turn on the decimal system, enter 9662
, then switch to hex and you'll get 25BE
. Then just add a backslash \
to the beginning.
git push origin HEAD:master
Git threw the below error when I tried simply git push
. So clearly this is because Git matches the local and remote branch while pushing commits. This is the push.default
behavior, you can find out more details here.
fatal: The upstream branch of your current branch does not match
the name of your current branch. To push to the upstream branch
on the remote, use
git push origin HEAD:<Branch_Name>
To push to the branch of the same name on the remote, use
git push origin <Branch_Name>
To choose either option permanently, see push.default in 'git help config'.
Set is used for setting object references, as opposed to assigning a value.
If you're trying to just count how many of your cells in a range are not blank try this:
=COUNTA(range)
Example: (assume that it starts from A1 downwards):
---------
Something
---------
Something
---------
---------
Something
---------
---------
Something
---------
=COUNTA(A1:A6)
returns 4
since there are two blank cells in there.
The code below fleshes out the answer above, displaying the screen size as a Toast.
//Determine screen size
if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE) {
Toast.makeText(this, "Large screen", Toast.LENGTH_LONG).show();
}
else if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_NORMAL) {
Toast.makeText(this, "Normal sized screen", Toast.LENGTH_LONG).show();
}
else if ((getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_SMALL) {
Toast.makeText(this, "Small sized screen", Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(this, "Screen size is neither large, normal or small", Toast.LENGTH_LONG).show();
}
This code below displays the screen density as a Toast.
//Determine density
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int density = metrics.densityDpi;
if (density == DisplayMetrics.DENSITY_HIGH) {
Toast.makeText(this, "DENSITY_HIGH... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
else if (density == DisplayMetrics.DENSITY_MEDIUM) {
Toast.makeText(this, "DENSITY_MEDIUM... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
else if (density == DisplayMetrics.DENSITY_LOW) {
Toast.makeText(this, "DENSITY_LOW... Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(this, "Density is neither HIGH, MEDIUM OR LOW. Density is " + String.valueOf(density), Toast.LENGTH_LONG).show();
}
Try to run either
SELECT USER();
or
SELECT CURRENT_USER();
It can sometimes be different, USER() will return by which login you attempted to authenticate and CURRENT_USER() will return how you were actually allowed to authenticate.
pgrep -f process_name > any_file_name
sed -i 's/^/kill /' any_file_name
chmod 777 any_file_name
./any_file_name
for example 'pgrep -f firefox' will grep the PID of running 'firefox' and will save this PID to a file called 'any_file_name'. 'sed' command will add the 'kill' in the beginning of the PID number in 'any_file_name' file. Third line will make 'any_file_name' file executable. Now forth line will kill the PID available in the file 'any_file_name'. Writing the above four lines in a file and executing that file can do the control-C. Working absolutely fine for me.
Very simple 2 string answer to your question:
$array_1 = array(
'0' => 'zero',
'1' => 'one',
'2' => 'two',
'3' => 'three',
);
At first you insert anything to your third element with array_splice and then assign a value to this element:
array_splice($array_1, 3, 0 , true);
$array_1[3] = array('sample_key' => 'sample_value');
You're trying to assign the result of the add operation to resultArrGame, and add can either return true or false, depending on if the operation was successful or not. What you want is probably just:
resultArrGame.add(txt.Game.getText().toString());
If you want to return from an outer function with an error without exit
ing you can use this trick:
do-something-complex() {
# Using `return` here would only return from `fail`, not from `do-something-complex`.
# Using `exit` would close the entire shell.
# So we (ab)use a different feature. :)
fail() { : "${__fail_fast:?$1}"; }
nested-func() {
try-this || fail "This didn't work"
try-that || fail "That didn't work"
}
nested-func
}
Trying it out:
$ do-something-complex
try-this: command not found
bash: __fail_fast: This didn't work
This has the added benefit/drawback that you can optionally turn off this feature: __fail_fast=x do-something-complex
.
Note that this causes the outermost function to return 1.
They're not bad practice, they're just another tool and they add flexibility.
For use as a standard page element... they're good, because they're a simple and reliable way to separate content onto several pages. Especially for user-generated content, it may be useful to "sandbox" internal pages into an iframe
so poor markup doesn't affect the main page. The downside is that if you introduce multiple layers of scrolling (one for the browser, one for the iframe
) your users will get frustrated. Like adzm said, you don't want to use an iframe
for primary navigation, but think about them as a text/markup equivalent to the way a video or another media file would be embedded.
For scripting background events, the choice is generally between a hidden iframe
and XmlHttpRequest
to load content for the current page. The difference there is that an iframe
generates a page load, so you can move back and forward in browser cache with most browsers. Notice that Google, who uses XmlHttpRequest
all over the place, also uses iframe
s in certain cases to allow a user to move back and forward in browser history.
>>> import datetime
>>> d = datetime.datetime.strptime('2011-06-09', '%Y-%m-%d')
>>> d.strftime('%b %d,%Y')
'Jun 09,2011'
In pre-2.5 Python, you can replace datetime.strptime
with time.strptime
, like so (untested): datetime.datetime(*(time.strptime('2011-06-09', '%Y-%m-%d')[0:6]))
It's worth noting that an OS has one queue for both System.err and System.out. Consider the following code:
public class PrintQueue {
public static void main(String[] args) {
for(int i = 0; i < 100; i++) {
System.out.println("out");
System.err.println("err");
}
}
}
If you compile and run the program, you will see that the order of outputs in console is mixed up.
An OS will remain right order if you work either with System.out or System.err only. But it can randomly choose what to print next to console, if you use both of these.
Even in this code snippet you can see that the order is mixed up sometimes:
public class PrintQueue {
public static void main(String[] args) {
System.out.println("out");
System.err.println("err");
}
}
In my case I use a template component in Blazor.
<BTable ID="Table1" TotalRows="MyList.Count()">
The problem is calling a method (Count) in the component header. To resolve the problem I changed it like this :
int total = MyList.Count();
and later :
<BTable ID="Table1" TotalRows="total">
if the map is short you can do:
ImmutableMap.of(key, value, key2, value2); // ...up to five k-v pairs
If it is longer then:
ImmutableMap.builder()
.put(key, value)
.put(key2, value2)
// ...
.build();
The best way to do it without any headache is to use the
\tablefootnote
command from the tablefootnote
package. Add the following to your preamble:
\usepackage{tablefootnote}
It just works without the need of additional tricks.
I recently used Spring Security 3.0 for this (combined with Wicket btw), and am quite happy with it. Here's a good thorough tutorial and documentation. Also take a look at this tutorial which gives a good explanation of the hashing/salting/decoding setup for Spring Security 2.
You're very close. Use same type on both sides, and include ()
.
ArrayList<Class> myArray = new ArrayList<Class>();
Adding to the accepted answer, further optimization can be achieved by using a list to store primes and printing them after generation.
import math
Primes_Upto = 101
Primes = [2]
for num in range(3,Primes_Upto,2):
if all(num%i!=0 for i in Primes):
Primes.append(num)
for i in Primes:
print i
In addition to Fuji's response, we can make the handler reusable turning it into an attached property:
public static class HyperlinkExtensions
{
public static bool GetIsExternal(DependencyObject obj)
{
return (bool)obj.GetValue(IsExternalProperty);
}
public static void SetIsExternal(DependencyObject obj, bool value)
{
obj.SetValue(IsExternalProperty, value);
}
public static readonly DependencyProperty IsExternalProperty =
DependencyProperty.RegisterAttached("IsExternal", typeof(bool), typeof(HyperlinkExtensions), new UIPropertyMetadata(false, OnIsExternalChanged));
private static void OnIsExternalChanged(object sender, DependencyPropertyChangedEventArgs args)
{
var hyperlink = sender as Hyperlink;
if ((bool)args.NewValue)
hyperlink.RequestNavigate += Hyperlink_RequestNavigate;
else
hyperlink.RequestNavigate -= Hyperlink_RequestNavigate;
}
private static void Hyperlink_RequestNavigate(object sender, System.Windows.Navigation.RequestNavigateEventArgs e)
{
Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
e.Handled = true;
}
}
And use it like this:
<TextBlock>
<Hyperlink NavigateUri="https://stackoverflow.com"
custom:HyperlinkExtensions.IsExternal="true">
Click here
</Hyperlink>
</TextBlock>
Joining fails if the DataFrames have some column names in common. The simplest way around it is to include an lsuffix
or rsuffix
keyword like so:
restaurant_review_frame.join(restaurant_ids_dataframe, on='business_id', how='left', lsuffix="_review")
This way, the columns have distinct names. The documentation addresses this very problem.
Or, you could get around this by simply deleting the offending columns before you join. If, for example, the stars in restaurant_ids_dataframe
are redundant to the stars in restaurant_review_frame
, you could del restaurant_ids_dataframe['stars']
.
I'd consider the patterns you are using for your system, the naming conventions / cataloguing / grouping of classes of tends to be defined by the pattern used. Personally, I stick to these naming conventions as they are the most likely way for another person to be able to pick up my code and run with it.
For example UserRecordsClerk might be better explained as extending a generic RecordsClerk interface that both UserRecordsClerk and CompanyRecordsClerk implement and then specialise on, meaning one can look at the methods in the interface to see what the its subclasses do / are generally for.
See a book such as Design Patterns for info, it's an excellent book and might help you clear up where you're aiming to be with your code - if you aren't already using it! ;o)
I reckon so long as your pattern is well chosen and used as far as is appropriate, then pretty uninventive straightforward class names should suffice!
You can return the state this way:
$state.go($state.$current.parent.self.name, $state.params);
An example:
(function() {
'use strict'
angular.module('app')
.run(Run);
/* @ngInject */
function Run($rootScope, $state) {
$rootScope.back = function() {
$state.go($state.$current.parent.self.name, $state.params);
};
};
})();
Use the correct call: strptime
is a classmethod of the datetime.datetime
class, it's not a function in the datetime
module.
self.date = datetime.datetime.strptime(self.d, "%Y-%m-%d")
As mentioned by Jon Clements in the comments, some people do from datetime import datetime
, which would bind the datetime
name to the datetime
class, and make your initial code work.
To identify which case you're facing (in the future), look at your import statements
import datetime
: that's the module (that's what you have right now).from datetime import datetime
: that's the class.iconv -f FROM-ENCODING -t TO-ENCODING file.txt
Also there are iconv-based tools in many languages.
Chiming in on this old thread -- the OP stated HH:MM:SS, and many of the solutions work, until you realize you need more than 24 hours listed. And maybe you don't want more than a single line of code. Here you go:
d=(s)=>{f=Math.floor;g=(n)=>('00'+n).slice(-2);return f(s/3600)+':'+g(f(s/60)%60)+':'+g(s%60)}
It returns H+:MM:SS. To use it, simply use:
d(91260); // returns "25:21:00"
d(960); // returns "0:16:00"
...I tried to get it to use the least amount of code possible, for a nice one-liner approach.
Here is a solution to get the country based on an international phone number without using the Google library.
Let me explain first why it is so difficult to figure out the country. The country code of few countries is 1 digit, 2, 3 or 4 digits. That would be simple enough. But the country code 1 is not just used for US, but also for Canada and some smaller places:
1339 USA
1340 Virgin Islands (Caribbean Islands)
1341 USA
1342 not used
1343 Canada
Digits 2..4 decide, if it is US or Canada or ... There is no easy way to figure out the country, like the first xxx are Canada, the rest US.
For my code, I defined a class which holds information for ever digit:
public class DigitInfo {
public char Digit;
public Country? Country;
public DigitInfo?[]? Digits;
}
A first array holds the DigitInfos for the first digit in the number. The second digit is used as an index into DigitInfo.Digits. One travels down that Digits chain, until Digits is empty. If Country is defined (i.e. not null) that value gets returned, otherwise any Country defined earlier gets returned:
country code 1: byPhone[1].Country is US
country code 1236: byPhone[1].Digits[2].Digits[3].Digits[6].Country is Canada
country code 1235: byPhone[1].Digits[2].Digits[3].Digits[5].Country is null. Since
byPhone[1].Country is US, also 1235 is US, because no other
country was found in the later digits
Here is the method which returns the country based on the phone number:
/// <summary>
/// Returns the Country based on an international dialing code.
/// </summary>
public static Country? GetCountry(ReadOnlySpan<char> phoneNumber) {
if (phoneNumber.Length==0) return null;
var isFirstDigit = true;
DigitInfo? digitInfo = null;
Country? country = null;
foreach (var digitChar in phoneNumber) {
var digitIndex = digitChar - '0';
if (isFirstDigit) {
isFirstDigit = false;
digitInfo = ByPhone[digitIndex];
} else {
if (digitInfo!.Digits is null) return country;
digitInfo = digitInfo.Digits[digitIndex];
}
if (digitInfo is null) return country;
country = digitInfo.Country??country;
}
return country;
}
The rest of the code (digitInfos for every country of the world, test code, ...) is too big to be posted here, but it can be found on Github: https://github.com/PeterHuberSg/WpfWindowsLib/blob/master/WpfWindowsLib/CountryCode.cs
The code is part of a WPF TextBox and the library contains also other controls for email addresses, etc. A more detailed description is on CodeProject: International Phone Number Validation Explained in Detail
I will demonstrate with a complete example
Create your database this way
import android.content.Context
import android.database.sqlite.SQLiteDatabase
import android.database.sqlite.SQLiteOpenHelper
class DBHelper(context: Context) : SQLiteOpenHelper(context, DATABASE_NAME, null, DATABASE_VERSION) {
override fun onCreate(db: SQLiteDatabase) {
val createProductsTable = ("CREATE TABLE " + Business.TABLE + "("
+ Business.idKey + " INTEGER PRIMARY KEY AUTOINCREMENT ,"
+ Business.KEY_a + " TEXT, "
+ Business.KEY_b + " TEXT, "
+ Business.KEY_c + " TEXT, "
+ Business.KEY_d + " TEXT, "
+ Business.KEY_e + " TEXT )")
db.execSQL(createProductsTable)
}
override fun onUpgrade(db: SQLiteDatabase, oldVersion: Int, newVersion: Int) {
// Drop older table if existed, all data will be gone!!!
db.execSQL("DROP TABLE IF EXISTS " + Business.TABLE)
// Create tables again
onCreate(db)
}
companion object {
//version number to upgrade database version
//each time if you Add, Edit table, you need to change the
//version number.
private val DATABASE_VERSION = 1
// Database Name
private val DATABASE_NAME = "business.db"
}
}
Then create a class to facilitate CRUD -> Create|Read|Update|Delete
class Business {
var a: String? = null
var b: String? = null
var c: String? = null
var d: String? = null
var e: String? = null
companion object {
// Labels table name
const val TABLE = "Business"
// Labels Table Columns names
const val rowIdKey = "_id"
const val idKey = "id"
const val KEY_a = "a"
const val KEY_b = "b"
const val KEY_c = "c"
const val KEY_d = "d"
const val KEY_e = "e"
}
}
Now comes the magic
import android.content.ContentValues
import android.content.Context
class SQLiteDatabaseCrud(context: Context) {
private val dbHelper: DBHelper = DBHelper(context)
fun updateCart(id: Int, mBusiness: Business) {
val db = dbHelper.writableDatabase
val valueToChange = mBusiness.e
val values = ContentValues().apply {
put(Business.KEY_e, valueToChange)
}
db.update(Business.TABLE, values, "id=$id", null)
db.close() // Closing database connection
}
}
you must create your ProductsAdapter which must return a CursorAdapter
So in an activity just call the function like this
internal var cursor: Cursor? = null
internal lateinit var mProductsAdapter: ProductsAdapter
mSQLiteDatabaseCrud = SQLiteDatabaseCrud(this)
try {
val mBusiness = Business()
mProductsAdapter = ProductsAdapter(this, c = todoCursor, flags = 0)
lstProducts.adapter = mProductsAdapter
lstProducts.onItemClickListener = OnItemClickListener { parent, view, position, arg3 ->
val cur = mProductsAdapter.getItem(position) as Cursor
cur.moveToPosition(position)
val id = cur.getInt(cur.getColumnIndexOrThrow(Business.idKey))
mBusiness.e = "this will replace the 0 in a specific position"
mSQLiteDatabaseCrud?.updateCart(id ,mBusiness)
}
cursor = dataBaseMCRUD!!.productsList
mProductsAdapter.swapCursor(cursor)
} catch (e: Exception) {
Log.d("ExceptionAdapter :",""+e)
}
Here's a more interesting implementation of multi line lambdas. It's not possible to achieve because of how python use indents as a way to structure code.
But luckily for us, indent formatting can be disabled using arrays and parenthesis.
As some already pointed out, you can write your code as such:
lambda args: (expr1, expr2,... exprN)
In theory if you're guaranteed to have evaluation from left to right it would work but you still lose values being passed from one expression to an other.
One way to achieve that which is a bit more verbose is to have
lambda args: [lambda1, lambda2, ..., lambdaN]
Where each lambda receives arguments from the previous one.
def let(*funcs):
def wrap(args):
result = args
for func in funcs:
if not isinstance(result, tuple):
result = (result,)
result = func(*result)
return result
return wrap
This method let you write something that is a bit lisp/scheme like.
So you can write things like this:
let(lambda x, y: x+y)((1, 2))
A more complex method could be use to compute the hypotenuse
lst = [(1,2), (2,3)]
result = map(let(
lambda x, y: (x**2, y**2),
lambda x, y: (x + y) ** (1/2)
), lst)
This will return a list of scalar numbers so it can be used to reduce multiple values to one.
Having that many lambda is certainly not going to be very efficient but if you're constrained it can be a good way to get something done quickly then rewrite it as an actual function later.
$('.slide-link[data-slide="0"]').addClass('active');
it works down the tree
Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.
As a complete new at javascript, I just had the same problem on my side here. The mistake I did, was that I used:
<script type="text.javascript">
console.log("bla bla bla");
</script>
instead of:
<script>
console.log("bla bla bla");
</script>
using the
type="text.javascript"
had the result of not producing the log in the console.
the solution is implementing anonymous class in this manner:
import org.openqa.selenium.Point;
import org.openqa.selenium.interactions.HasInputDevices;
import org.openqa.selenium.interactions.Mouse;
import org.openqa.selenium.interactions.internal.Coordinates;
.....
final Point image = page.findImage("C:\\Pictures\\marker.png") ;
Mouse mouse = ((HasInputDevices) driver).getMouse();
Coordinates imageCoordinates = new Coordinates() {
public Point onScreen() {
throw new UnsupportedOperationException("Not supported yet.");
}
public Point inViewPort() {
Response response = execute(DriverCommand.GET_ELEMENT_LOCATION_ONCE_SCROLLED_INTO_VIEW,
ImmutableMap.of("id", getId()));
@SuppressWarnings("unchecked")
Map<String, Number> mapped = (Map<String, Number>) response.getValue();
return new Point(mapped.get("x").intValue(), mapped.get("y").intValue());
}
public Point onPage() {
return image;
}
public Object getAuxiliary() {
// extract the selenium imageElement id (imageElement.toString() and parse out the "{sdafbsdkjfh}" format id) and return it
}
};
mouse.mouseMove(imageCoordinates);
Code check:
This is offtopic here but the people over at CodeReview are more than happy to help you.
I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.
Lists:
As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List
.
Lists are very straightforward to use but take a look at the related documentation anyway.
A very simple example to keep multiple bikes in a list:
List<Motorbike> bikes = new List<Motorbike>();
bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });
And to iterate over the list you can use the foreach
statement:
foreach(var bike in bikes) {
Console.WriteLine(bike.make);
}
The simplest solution:
List<String> list = Files.readAllLines(Paths.get("path/of/text"), StandardCharsets.UTF_8);
String[] a = list.toArray(new String[list.size()]);
Note that java.nio.file.Files is since 1.7
I have Windows 8 installed on my machine, and the aspnet_regiis.exe tool did not worked for me either.
The solution that worked for me is posted on this link, on the answer by Neha: System.ServiceModel.Activation.HttpModule error
Everywhere the problem to this solution was mentioned as re-registering aspNet by using aspnet_regiis.exe. But this did not work for me.
Though this is a valid solution (as explained beautifully here)
but it did not work with Windows 8.
For Windows 8 you need to Windows features and enable everything under ".Net Framework 3.5" and ".Net Framework 4.5 Advanced Services".
Thanks Neha
I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.
You can use OR()
to group expressions (as well as AND()
):
=IF(OR(condition1, condition2), true, false)
=IF(AND(condition1, condition2), true, false)
So if you wanted to test for "cat" and "22":
=IF(AND(SEARCH("cat",a1),SEARCH("22",a1)),"cat and 22","none")
There is a much simpler way. Put your picture in a comment box within the description cell. That way you only have one column and when you sort the picture will always stay with the description. Okay... Right click the cell containing the description... Insert comment...right click the outer border... Format comment...colours and lines tab... Colour drop down...Fill effects...Picture tab...select picture...browse for your picture (it might be best to keep all pictures in one folder for ease of placement)...ok... you will probably need to go to the size tab and frig around with the height and width. Done... You now only need to mouse over the red in the top right corner of the cell and the picture will appear...like magic.
This method means that the row height can be kept to a minimum and the pictures can be as big as you like.
Well, technically it does not have to be on the same line as long as there is no character between the ending ">" from start tag and the starting "<" from the closing tag. That is you need to end with
...></textarea>
as in the example below:
<p><label>Comments:<br>
<textarea id = "comments" rows = "4" cols = "36"
placeholder = "Enter comments here"
class = "valid"></textarea>
</label>
</p>
You can try just hidding the keyboard. Something like this:
InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
For smaller arrays <10000 elements:
using System.Linq;
int firstArray = {5,4,2};
int secondArray = {3,2,1};
int[] result = firstArray.ToList().Concat(secondArray.ToList()).toArray();
It is technically possible to put a caption on an ImageButton
if you really want to do it. Just put a TextView
over the ImageButton
using FrameLayout
. Just remember to not make the Textview
clickable.
Example:
<FrameLayout>
<ImageButton
android:id="@+id/button_x"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@null"
android:scaleType="fitXY"
android:src="@drawable/button_graphic" >
</ImageButton>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:clickable="false"
android:text="TEST TEST" >
</TextView>
</FrameLayout>
I would use:
awk 'FNR >= 16224 && FNR <= 16482' my_file > extracted.txt
FNR contains the record (line) number of the line being read from the file.
Good contributions the previous ones.
import sys; print(sys.version)
def ingreso(nombre):
print('Hi ', nombre, type(nombre))
def bienvenida(nombre):
print("Hi "+nombre+", bye ")
nombre = raw_input("Enter your name: ")
ingreso(nombre)
bienvenida(nombre)
#Works in Python 2 and 3:

print(input("Your name: "))
Enter your name: Joe ('Hi ', 'Joe', <type 'str'>) Hi Joe, bye Your name: Joe Joe
Thanks!

But there was nothing wrong with your original of using an if inside of a while True.
This was a pain, using netBeans IDE 7.2.
Add a resource folder to the src folder:
After the clean/build this structure is propogated into the Build folder:
To access the resources:
dlabel = new JLabel(new ImageIcon(getClass().getClassLoader().getResource("resources/images/logo.png")));
and:
if (common.readFile(getClass().getResourceAsStream("/resources/allwise.ini"), buf).equals("OK")) {
worked for me. Note that in one case there is a leading "/" and in the other there isn't. So the root of the path to the resources is the "classes" folder within the build folder.
Double click on the executable jar file in the dist folder. The path to the resources still works.
To make the answer more re-usable for things other than just the datepicker change function you can create a prototype to handle this for you.
// safety check to see if the prototype name is already defined
Function.prototype.method = function (name, func) {
if (!this.prototype[name]) {
this.prototype[name] = func;
return this;
}
};
Date.method('inPast', function () {
return this < new Date($.now());// the $.now() requires jQuery
});
// including this prototype as using in example
Date.method('addDays', function (days) {
var date = new Date(this);
date.setDate(date.getDate() + (days));
return date;
});
If you dont like the safety check you can use the conventional way to define prototypes:
Date.prototype.inPast = function(){
return this < new Date($.now());// the $.now() requires jQuery
}
Example Usage
var dt = new Date($.now());
var yesterday = dt.addDays(-1);
var tomorrow = dt.addDays(1);
console.log('Yesterday: ' + yesterday.inPast());
console.log('Tomorrow: ' + tomorrow.inPast());
I just installed WAMP 3 on Windows 10 and did not have Apache in the WampServer system tray options.
But the httpd.conf file is located here:
C:\wamp64\bin\apache\apache2.4.17\conf\
In that folder, open httpd.conf
with a text editor. Then go to line 62-63 and change 80 to 8080 like this:
Listen 0.0.0.0:8080
Listen [::0]:8080
Then go to the WampServer icon in the system tray and right-click > Exit, then Open WampServer again, and it should now turn green.
Now go to localhost:8080
to see your server config page.
You can also use the update-golang script:
update-golang is a script to easily fetch and install new Golang releases with minimum system intrusion
git clone https://github.com/udhos/update-golang
cd update-golang
sudo ./update-golang.sh
That's right, if you're on a mac(unix) you won't see .git in finder(the file browser). You can follow the directions above to delete and there are git commands that allow you to delete files as well(they are sometimes difficult to work with and learn, for example: on making a 'git rm -r ' command you might be prompted with a .git/ not found. Here is the git command specs:
usage: git rm [options] [--] ...
-n, --dry-run dry run
-q, --quiet do not list removed files
--cached only remove from the index
-f, --force override the up-to-date check
-r allow recursive removal
--ignore-unmatch exit with a zero status even if nothing matched
When I had to do this, deleting the objects and refs didn't matter. After I deleted the other files in the .git, I initialized a git repo with 'git init' and it created an empty repo.
Starting from freemarker 2.3.7, you can use this syntax :
${(object.attribute)!}
or, if you want display a default text when the attribute is null
:
${(object.attribute)!"default text"}
I have faced this issue.
Please look at the attached image,

Intellij IDEA 15: File->Project Structure...->Project Settings->Libraries
AST_NODE* Statement(AST_NODE* node)
is missing a semicolon (a major clue was the error message "In function ‘Statement’: ...") and so is line 24,
return node
(Once you fix those, you will encounter other problems, some of which are mentioned by others here.)
You can use regular expressions like this:
SELECT * FROM pet WHERE name REGEXP 'Bob|Smith';
If you're on Node JS and you're seeing this error in a Class you've added to support a Cucumber test, it's because Cucumber will automatically try to run anything that exports a function, and NodeJS internally converts a Class to a function.
So instead of this:
module.exports = MyClass;
do this:
module.exports.MyClass = MyClass;
Then, when you import it into your steps file, do it like this:
let MyClass = require("myclass.js").MyClass;
This way you're not exporting a function. Read more here.
Open $CATALINA_BASE/conf/web.xml
and find this
<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly -->
<!-- created sessions by modifying the value below. -->
<session-config>
<session-timeout>30</session-timeout>
</session-config>
all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.
This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different
The following command will add all the lines(first field of the awk output)
awk '{s+=$1} END {print s}' filename
let text:String = "Hello Friend"
let searchRange:NSRange = NSRange(location:0,length: text.characters.count)
let range:Range`<Int`> = Range`<Int`>.init(start: searchRange.location, end: searchRange.length)
The unset
array_search
has some pretty terrible side effects because it can accidentally strip the first element off your array regardless of the value:
// bad side effects
$a = [0,1,2,3,4,5];
unset($a[array_search(3, $a)]);
unset($a[array_search(6, $a)]);
$this->log_json($a);
// result: [1,2,4,5]
// what? where is 0?
// it was removed because false is interpreted as 0
// goodness
$b = [0,1,2,3,4,5];
$b = array_diff($b, [3,6]);
$this->log_json($b);
// result: [0,1,2,4,5]
If you know that the value is guaranteed to be in the array, go for it, but I think the array_diff
is far safer. (I'm using php7)
Would be cool if someone could give me feedback on this one, I used the JUNIT without assert Pattern because it's easy and fast to get it running in Eclipse, I could also have just defined a main method. By the way, I am assuming rand5 gives values 0-4, adding 1 would make it 1-5, same with rand7... So the discussion should be on the solution, it's distribution, not on wether it goes from 0-4 or 1-5...
package random;
import java.util.Random;
import org.junit.Test;
public class RandomTest {
@Test
public void testName() throws Exception {
long times = 100000000;
int indexes[] = new int[7];
for(int i = 0; i < times; i++) {
int rand7 = rand7();
indexes[rand7]++;
}
for(int i = 0; i < 7; i++)
System.out.println("Value " + i + ": " + indexes[i]);
}
public int rand7() {
return (rand5() + rand5() + rand5() + rand5() + rand5() + rand5() + rand5()) % 7;
}
public int rand5() {
return new Random().nextInt(5);
}
}
When I run it, I get this result:
Value 0: 14308087
Value 1: 14298303
Value 2: 14279731
Value 3: 14262533
Value 4: 14269749
Value 5: 14277560
Value 6: 14304037
This seems like a very fair distribution, doesn't it?
If I add rand5() less or more times (where the amount of times is not divisible by 7), the distribution clearly shows offsets. For instance, adding rand5()
3 times:
Value 0: 15199685
Value 1: 14402429
Value 2: 12795649
Value 3: 12796957
Value 4: 14402252
Value 5: 15202778
Value 6: 15200250
So, this would lead to the following:
public int rand(int range) {
int randomValue = 0;
for(int i = 0; i < range; i++) {
randomValue += rand5();
}
return randomValue % range;
}
And then, I could go further:
public static final int ORIGN_RANGE = 5;
public static final int DEST_RANGE = 7;
@Test
public void testName() throws Exception {
long times = 100000000;
int indexes[] = new int[DEST_RANGE];
for(int i = 0; i < times; i++) {
int rand7 = convertRand(DEST_RANGE, ORIGN_RANGE);
indexes[rand7]++;
}
for(int i = 0; i < DEST_RANGE; i++)
System.out.println("Value " + i + ": " + indexes[i]);
}
public int convertRand(int destRange, int originRange) {
int randomValue = 0;
for(int i = 0; i < destRange; i++) {
randomValue += rand(originRange);
}
return randomValue % destRange;
}
public int rand(int range) {
return new Random().nextInt(range);
}
I tried this replacing the destRange and originRange with various values (even 7 for ORIGIN and 13 for DEST), and I get this distribution:
Value 0: 7713763
Value 1: 7706552
Value 2: 7694697
Value 3: 7695319
Value 4: 7688617
Value 5: 7681691
Value 6: 7674798
Value 7: 7680348
Value 8: 7685286
Value 9: 7683943
Value 10: 7690283
Value 11: 7699142
Value 12: 7705561
What I can conclude from here is that you can change any random to anyother by suming the origin random "destination" times. This will get a kind of gaussian distribution (being the middle values more likely, and the edge values more uncommon). However, the modulus of destination seems to distribute itself evenly across this gaussian distribution... It would be great to have feedback from a mathematician...
What is cool is that the cost is 100% predictable and constant, whereas other solutions cause a small probability of infinite loop...
Yes. We have inbuilt function to remove an individual character of a string in java, that is, deleteCharAt
For example,
public class StringBuilderExample
{
public static void main(String[] args)
{
StringBuilder sb = new StringBuilder("helloworld");
System.out.println("Before : " + sb);
sb = sb.deleteCharAt(3);
System.out.println("After : " + sb);
}
}
Output
Before : helloworld
After : heloworld

For MAC VSC users the best setup is:
1) press 'shift+cmd+P' and type:
Shell Command: install 'code' command in PATH
Press ENTER (this will install code command to get to the bash_profile easily)
2 ) you can now run: code ~/.bash_profile
to open the empty bash_profile
3) enter a new function in there:
function lazygit() {
git add .
git commit -m "$*"
git push
}
4) now restart VSC
5) make a change, save it and type lazygit message
to run the three commands concurrently
However there are very good answers already available for this. Here is my answer:
1. set.stream().forEach(System.out::println); // It simply uses stream to display set values
2. set.forEach(System.out::println); // It uses Enhanced forEach to display set values
Also, if this Set is of Custom class type, for eg: Customer.
Set<Customer> setCust = new HashSet<>();
Customer c1 = new Customer(1, "Hena", 20);
Customer c2 = new Customer(2, "Meena", 24);
Customer c3 = new Customer(3, "Rahul", 30);
setCust.add(c1);
setCust.add(c2);
setCust.add(c3);
setCust.forEach((k) -> System.out.println(k.getId()+" "+k.getName()+" "+k.getAge()));
// Customer class:
class Customer{
private int id;
private String name;
private int age;
public Customer(int id,String name,int age){
this.id=id;
this.name=name;
this.age=age;
} // Getter, Setter methods are present.}
A simple fix for this is to install the Google Cast extension. If you don't have a Chromecast, or don't want to use the extension, no problem; just don't use the extension.

I faced this issue because my $(elem).click(function(){});
script was placed inline in a div that was set to style="display:none;"
.
When the css display was switched to block, the script would add the event listener a second time. I moved the script to a separate .js file and the duplicate event listener was no longer initiated.
I am using this extension:
extension String {
func replaceCharacters(characters: String, toSeparator: String) -> String {
let characterSet = NSCharacterSet(charactersInString: characters)
let components = self.componentsSeparatedByCharactersInSet(characterSet)
let result = components.joinWithSeparator("")
return result
}
func wipeCharacters(characters: String) -> String {
return self.replaceCharacters(characters, toSeparator: "")
}
}
Usage:
let token = "<34353 43434>"
token.replaceCharacters("< >", toString:"+")
It depends on architecture/jdk. For a modern JDK and 64bit architecture, an object has 12-bytes header and padding by 8 bytes - so minimum object size is 16 bytes. You can use a tool called Java Object Layout to determine a size and get details about object layout and internal structure of any entity or guess this information by class reference. Example of an output for Integer on my environment:
Running 64-bit HotSpot VM.
Using compressed oop with 3-bit shift.
Using compressed klass with 3-bit shift.
Objects are 8 bytes aligned.
Field sizes by type: 4, 1, 1, 2, 2, 4, 4, 8, 8 [bytes]
Array element sizes: 4, 1, 1, 2, 2, 4, 4, 8, 8 [bytes]
java.lang.Integer object internals:
OFFSET SIZE TYPE DESCRIPTION VALUE
0 12 (object header) N/A
12 4 int Integer.value N/A
Instance size: 16 bytes (estimated, the sample instance is not available)
Space losses: 0 bytes internal + 0 bytes external = 0 bytes total
So, for Integer, instance size is 16 bytes, because 4-bytes int compacted in place right after header and before padding boundary.
Code sample:
import org.openjdk.jol.info.ClassLayout;
import org.openjdk.jol.util.VMSupport;
public static void main(String[] args) {
System.out.println(VMSupport.vmDetails());
System.out.println(ClassLayout.parseClass(Integer.class).toPrintable());
}

to_dict() Convert a SON document to a normal Python dictionary instance.
This is trickier than just dict(...) because it needs to be recursive.
I recently had this same problem. Unfortunately, NotifyIcon is only a Windows.Forms control at the moment, if you want to use it you are going to have to include that part of the framework. I guess that depends how much of a WPF purist you are.
If you want a quick and easy way of getting started check out this WPF NotifyIcon control on the Code Project which does not rely on the WinForms NotifyIcon at all. A more recent version seems to be available on the author's website and as a NuGet package. This seems like the best and cleanest way to me so far.
- Rich ToolTips rather than text
- WPF context menus and popups
- Command support and routed events
- Flexible data binding
- Rich balloon messages rather than the default messages provides by the OS
Check it out. It comes with an amazing sample app too, very easy to use, and you can have great looking Windows Live Messenger style WPF popups, tooltips, and context menus. Perfect for displaying an RSS feed, I am using it for a similar purpose.

Seems like you just forgot the comma to separate the classes. So based on your configuration the following will work:
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration,\
org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,\
org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration,\
org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration
Alternatively you could also define it as follow:
spring.autoconfigure.exclude[0]=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration
spring.autoconfigure.exclude[1]=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.autoconfigure.exclude[2]=org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
spring.autoconfigure.exclude[3]=org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration
You can either post HTML form to URL, which is mapped to servlet or insert your data in HttpServletRequest object you pass to jsp page.
If your npm version is lower than version 5 then install the higher version for getting the automatic generation of package-lock.json.
Example: Upgrade your current npm to version 6.14.0
npm i -g [email protected]

npm view npm versions
I don't see a way to run a single untagged test within a test class but I am providing my workflow since it seems to be useful for anyone who runs into this question.
From within a sbt session:
test:testOnly *YourTestClass
(The asterisk is a wildcard, you could specify the full path com.example.specs.YourTestClass
.)
All tests within that test class will be executed. Presumably you're most concerned with failing tests, so correct any failing implementations and then run:
test:testQuick
... which will only execute tests that failed. (Repeating the most recently executed test:testOnly
command will be the same as test:testQuick
in this case, but if you break up your test methods into appropriate test classes you can use a wildcard to make test:testQuick
a more efficient way to re-run failing tests.)
Note that the nomenclature for test in ScalaTest is a test class, not a specific test method, so all untagged methods are executed.
If you have too many test methods in a test class break them up into separate classes or tag them appropriately. (This could be a signal that the class under test is in violation of single responsibility principle and could use a refactoring.)
function calcSize($size,$accuracy=2) {
$units = array('b','Kb','Mb','Gb');
foreach($units as $n=>$u) {
$div = pow(1024,$n);
if($size > $div) $output = number_format($size/$div,$accuracy).$u;
}
return $output;
}
Unix cp
doesn't 'support both directories and files':
betelgeuse:tmp james$ cp source/ dest/
cp: source/ is a directory (not copied).
To make cp copy a directory, you have to manually tell cp that it's a directory, by using the '-r' flag.
There is some disconnect here though - cp -r
when passed a filename as the source will happily copy just the single file; copytree won't.
No. You have to make your own like this:
boolean tryParseInt(String value) {
try {
Integer.parseInt(value);
return true;
} catch (NumberFormatException e) {
return false;
}
}
...and you can use it like this:
if (tryParseInt(input)) {
Integer.parseInt(input); // We now know that it's safe to parse
}
EDIT (Based on the comment by @Erk)
Something like follows should be better
public int tryParse(String value, int defaultVal) {
try {
return Integer.parseInt(value);
} catch (NumberFormatException e) {
return defaultVal;
}
}
When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.
public int tryParse(String value) {
return tryParse(value, 0)
}
Simple way
Create a new java class
public class ActivityName extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null){
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new Fragment_name_which_you_wantto_open()).commit();}
}
}
in your activity where u want to call fragment
Intent i = new Intent(Currentactivityname.this,ActivityName.class);
startActivity(i);
Another Method
Place frame layout in your activity where u want to open fragment
<FrameLayout
android:id="@+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
Paste this code where u want to open fragment
Fragment mFragment = null;
mFragment = new Name_of_fragment_which_you_want_to_open();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frameLayout, mFragment).commit();
OO Abstraction occurs during class level design, with the objective of hiding the implementation complexity of how the the features offered by an API / design / system were implemented, in a sense simplifying the 'interface' to access the underlying implementation.
The process of abstraction can be repeated at increasingly 'higher' levels (layers) of classes, which enables large systems to be built without increasing the complexity of code and understanding at each layer.
For example, a Java developer can make use of the high level features of FileInputStream without concern for how it works (i.e. file handles, file system security checks, memory allocation and buffering will be managed internally, and are hidden from consumers). This allows the implementation of FileInputStream
to be changed, and as long as the API (interface) to FileInputStream
remains consistent, code built against previous versions will still work.
Similarly, when designing your own classes, you will want to hide internal implementation details from others as far as possible.
In the Booch definition1, OO Encapsulation is achieved through Information Hiding, and specifically around hiding internal data (fields / members representing the state) owned by a class instance, by enforcing access to the internal data in a controlled manner, and preventing direct, external change to these fields, as well as hiding any internal implementation methods of the class (e.g. by making them private).
For example, the fields of a class can be made private
by default, and only if external access to these was required, would a get()
and/or set()
(or Property
) be exposed from the class. (In modern day OO languages, fields can be marked as readonly
/ final
/ immutable
which further restricts change, even within the class).
Example where NO information hiding has been applied (Bad Practice):
class Foo {
// BAD - NOT Encapsulated - code external to the class can change this field directly
// Class Foo has no control over the range of values which could be set.
public int notEncapsulated;
}
Example where field encapsulation has been applied:
class Bar {
// Improvement - access restricted only to this class
private int encapsulatedPercentageField;
// The state of Bar (and its fields) can now be changed in a controlled manner
public void setEncapsulatedField(int percentageValue) {
if (percentageValue >= 0 && percentageValue <= 100) {
encapsulatedPercentageField = percentageValue;
}
// else throw ... out of range
}
}
Example of immutable / constructor-only initialization of a field:
class Baz {
private final int immutableField;
public void Baz(int onlyValue) {
// ... As above, can also check that onlyValue is valid
immutableField = onlyValue;
}
// Further change of `immutableField` outside of the constructor is NOT permitted, even within the same class
}
Re : Abstraction vs Abstract Class
Abstract classes are classes which promote reuse of commonality between classes, but which themselves cannot directly be instantiated with new()
- abstract classes must be subclassed, and only concrete
(non abstract) subclasses may be instantiated. Possibly one source of confusion between Abstraction
and an abstract class
was that in the early days of OO, inheritance was more heavily used to achieve code reuse (e.g. with associated abstract base classes). Nowadays, composition is generally favoured over inheritance, and there are more tools available to achieve abstraction, such as through Interfaces, events / delegates / functions, traits / mixins etc.
Re : Encapsulation vs Information Hiding
The meaning of encapsulation appears to have evolved over time, and in recent times, encapsulation
can commonly also used in a more general sense when determining which methods, fields, properties, events etc to bundle into a class.
Quoting Wikipedia:
In the more concrete setting of an object-oriented programming language, the notion is used to mean either an information hiding mechanism, a bundling mechanism, or the combination of the two.
For example, in the statement
I've encapsulated the data access code into its own class
.. the interpretation of encapsulation is roughly equivalent to the Separation of Concerns or the Single Responsibility Principal (the "S" in SOLID), and could arguably be used as a synonym for refactoring.
[1] Once you've seen Booch's encapsulation cat picture you'll never be able to forget encapsulation - p46 of Object Oriented Analysis and Design with Applications, 2nd Ed

Thanks.. only one that fixed mine was the command prompt. Devenv is located under VisualStudio 12.0 Directory under common7\IDE if it helps..
my problem was that when connecting to SQL Database in the add reference wizard, to find the SERVERNAME. i found it by: running a query(SELECT @@SERVERNAME) inside SQL management studio and the reusl was my servername. I put that in my server name box and it worked all fine.
I was having this issue while running a SpringBoot project (Maven)
In my POM file I changed the java version from 11 to 8 and it worked:
<properties>
<java.version>8</java.version> //The default was 11
</properties>
Make sure to Load maven changes
else the change won't reflect.
Agreed with part of @Jeffrey Fox's answer:
max-age=0, must-revalidate and no-cache aren't exactly identical.
Not agreed with this part:
With no-cache, it would just show the cached content, which would be probably preferred by the user (better to have something stale than nothing at all).
What should implementations do when cache-control: no-cache
revalidation failed is just not specified in the RFC document. It's all up to implementations. They may throw a 504 error like cache-control: must-revalidate
or just serve a stale copy from cache.
If you add the favicon into the root/images folder with the name favicon.ico browser will automatically understand and get it as favicon.I tested and worked. your link must be www.website.com/images/favicon.ico
For more information look this answer:
Do you have to include <link rel="icon" href="favicon.ico" type="image/x-icon" />?
after some test: If you send an email to an outlook client, and the subject is >77 chars, and it needs to use "=?ISO"
inside the subject (in my case because of accents) then OutLook will "cut" the subject in the middle of it and mesh it all that comes after, including body text, attaches, etc... all a mesh!
I have several examples like this one:
Subject: =?ISO-8859-1?Q?Actas de la obra N=BA.20100154 (Expediente N=BA.20100182) "NUEVA RED FERROVIARIA.=
TRAMO=20BEASAIN=20OESTE(Pedido=20PC10/00123-125),=20BEASAIN".?=
To:
As you see, in the subject line it cutted on char 78 with a "=" followed by 2 or 3 line feeds, then continued with the rest of the subject baddly.
It was reported to me from several customers who all where using OutLook, other email clients deal with those subjects ok.
If you have no ISO on it, it doesn't hurt, but if you add it to your subject to be nice to RFC, then you get this surprise from OutLook. Bit if you don't add the ISOs, then iPhone email will not understand it(and attach files with names using such characters will not work on iPhones).
Python's built-in float
type has double precision (it's a C double
in CPython, a Java double
in Jython). If you need more precision, get NumPy and use its numpy.float128
.
It's also possible to to do this without the wrapper - div#main. You can center the #page-wrap using the margin: 0 auto; method and then use the left:-n; method to position the #sidebar and adding the width of #page-wrap.
body { background: black; }
#sidebar {
position: absolute;
left: 50%;
width: 200px;
height: 400px;
background: red;
margin-left: -230px;
}
#page-wrap {
width: 60px;
background: #fff;
height: 400px;
margin: 0 auto;
}
However, the sidebar would disappear beyond the browser viewport if the window was smaller than the content.
Nick's second answer is best though, because it's also more maintainable as you don't have to adjust #sidebar if you want to resize #page-wrap.
Hi i have a shorter version. this does same as a best answer. (it works on chrome 74.03)

With the new version of React Router (using 2.0.1 now), you can use an asterisk as a path to route all 'other paths'.
So it would look like this:
<Route route="/" component={App}>
<Route path=":area" component={Area}>
<Route path=":city" component={City} />
<Route path=":more-stuff" component={MoreStuff} />
</Route>
<Route path="*" component={NotFoundRoute} />
</Route>
I'm the creator of Restangular.
You can take a look at this CRUD example to see how you can PUT/POST/GET elements without all that URL configuration and $resource configuration that you need to do. Besides it, you can then use nested resources without any configuration :).
Check out this plunkr example:
http://plnkr.co/edit/d6yDka?p=preview
You could also see the README and check the documentation here https://github.com/mgonto/restangular
If you need some feature that's not there, just create an issue. I usually add features asked within a week, as I also use this library for all my AngularJS projects :)
Hope it helps!
You forgot the .class
:
if (value.getClass() == Integer.class) {
System.out.println("This is an Integer");
}
else if (value.getClass() == String.class) {
System.out.println("This is a String");
}
else if (value.getClass() == Float.class) {
System.out.println("This is a Float");
}
Note that this kind of code is usually the sign of a poor OO design.
Also note that comparing the class of an object with a class and using instanceof is not the same thing. For example:
"foo".getClass() == Object.class
is false, whereas
"foo" instanceof Object
is true.
Whether one or the other must be used depends on your requirements.
There are some changes required to JavaScript code to handle rendering based on user liking or not liking the page mandated by Facebook moving to Auth2.0 authorization.
Change is fairly simple:-
sessions has to be replaced by authResponse and uid by userID
Moreover given the requirement of the code and some issues faced by people(including me) in general with FB.login, use of FB.getLoginStatus is a better alternative. It saves query to FB in case user is logged in and has authenticated your app.
Refer to Response and Sessions Object section for info on how this might save query to FB server. http://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus/
Issues with FB.login and its fixes using FB.getLoginStatus. http://forum.developers.facebook.net/viewtopic.php?id=70634
Here is the code posted above with changes which worked for me.
$(document).ready(function(){
FB.getLoginStatus(function(response) {
if (response.status == 'connected') {
var user_id = response.authResponse.userID;
var page_id = "40796308305"; //coca cola
var fql_query = "SELECT uid FROM page_fan WHERE page_id =" + page_id + " and uid=" + user_id;
var the_query = FB.Data.query(fql_query);
the_query.wait(function(rows) {
if (rows.length == 1 && rows[0].uid == user_id) {
$("#container_like").show();
//here you could also do some ajax and get the content for a "liker" instead of simply showing a hidden div in the page.
} else {
$("#container_notlike").show();
//and here you could get the content for a non liker in ajax...
}
});
} else {
// user is not logged in
}
});
});
You can use $routeProvider resolve property to delay route change until data is loaded.
angular.module('app', ['ngRoute']).
config(['$routeProvider', function($routeProvider, EntitiesCtrlResolve, EntityCtrlResolve) {
$routeProvider.
when('/entities', {
templateUrl: 'entities.html',
controller: 'EntitiesCtrl',
resolve: EntitiesCtrlResolve
}).
when('/entity/:entityId', {
templateUrl: 'entity.html',
controller: 'EntityCtrl',
resolve: EntityCtrlResolve
}).
otherwise({redirectTo: '/entities'});
}]);
Notice that the resolve
property is defined on route.
EntitiesCtrlResolve
and EntityCtrlResolve
is constant objects defined in same file as EntitiesCtrl
and EntityCtrl
controllers.
// EntitiesCtrl.js
angular.module('app').constant('EntitiesCtrlResolve', {
Entities: function(EntitiesService) {
return EntitiesService.getAll();
}
});
angular.module('app').controller('EntitiesCtrl', function(Entities) {
$scope.entities = Entities;
// some code..
});
// EntityCtrl.js
angular.module('app').constant('EntityCtrlResolve', {
Entity: function($route, EntitiesService) {
return EntitiesService.getById($route.current.params.projectId);
}
});
angular.module('app').controller('EntityCtrl', function(Entity) {
$scope.entity = Entity;
// some code..
});
You have two objects both named bank_holiday
-- one a list and one a function. Disambiguate the two.
bank_holiday[month]
is raising an error because Python thinks bank_holiday
refers to the function (the last object bound to the name bank_holiday
), whereas you probably intend it to mean the list.
The easiest solution is to use conditional formatting if the IF Statement comes back false to change the font of the results cell to whatever color background is. Yes, technically the cell isn't blank, but you won't be able to see it's contents.
Try with array_intersect method
$id = $access_data['Privilege']['id'];
if(count(array_intersect($id,$user_access_arr)) == 0){
$this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));
}
check
System.getProperty("sun.jnu.encoding")
it seems to be the same encoding as the one used in your system's command line.
Try this:
<select id="sel">
<option value='1'>One</option>
<option value='2'>Two</option>
<option value='3'>Three</option>
</select>
<input type="button" value="Change option to 2" onclick="changeOpt()"/>
<script>
function changeOpt(){
document.getElementById("sel").options[1].selected = true;
alert("changed")
}
</script>
As WhirlWind said, you start at the beginning.
You swap cursor with each remaining value, including cursor itself, these are all new instances (I used an int[]
and array.clone()
in the example).
Then perform permutations on all these different lists, making sure the cursor is one to the right.
When there are no more remaining values (cursor is at the end), print the list. This is the stop condition.
public void permutate(int[] list, int pointer) {
if (pointer == list.length) {
//stop-condition: print or process number
return;
}
for (int i = pointer; i < list.length; i++) {
int[] permutation = (int[])list.clone();.
permutation[pointer] = list[i];
permutation[i] = list[pointer];
permutate(permutation, pointer + 1);
}
}
use below code it helps you....
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
options.inPurgeable = true;
Bitmap bm = BitmapFactory.decodeFile("your path of image",options);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG,40,baos);
// bitmap object
byteImage_photo = baos.toByteArray();
//generate base64 string of image
String encodedImage =Base64.encodeToString(byteImage_photo,Base64.DEFAULT);
//send this encoded string to server
Delete M2 and M2_HOME from user variables and move to system variables. That will solve the problem
Python 3.3 introduces Python Launcher for Windows that is installed into c:\Windows\
as py.exe
and pyw.exe
by the installer. The installer also creates associations with .py
and .pyw
. Then add #!python3
or #!python2
as the first lline. No need to add anything to the PATH
environment variable.
Update: Just install Python 3.3 from the official python.org/download. It will add also the launcher. Then add the first line to your script that has the .py
extension. Then you can launch the script by simply typing the scriptname.py
on the cmd line, od more explicitly by py scriptname.py
, and also by double clicking on the scipt icon.
The py.exe
looks for C:\PythonXX\python.exe
where XX
is related to the installed versions of Python at the computer. Say, you have Python 2.7.6 installed into C:\Python27
, and Python 3.3.3 installed into C:\Python33
. The first line in the script will be used by the Python launcher to choose one of the installed versions. The default (i.e. without telling the version explicitly) is to use the highest version of Python 2 that is available on the computer.
I experienced this error when using bindParam, and specifying PDO::PARAM_INT where I was actually passing a string. Changing to PDO::PARAM_STR fixed the error.

The complete article that works for me: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding
The part where we encode from Unicode/UTF-8 is
function utf8_to_b64( str ) {
return window.btoa(unescape(encodeURIComponent( str )));
}
function b64_to_utf8( str ) {
return decodeURIComponent(escape(window.atob( str )));
}
// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"
This is one of the most used methods nowadays.

It's the old bug in Java on Mac that got triggered by the Java Agent being used by the IDE when starting the app. This message is harmless and is safe to ignore. Oracle developer's comment:
The message is benign, there is no negative impact from this problem since both copies of that class are identical (compiled from the exact same source). It is purely a cosmetic issue.
The problem is fixed in Java 9 and in Java 8 update 152.
If it annoys you or affects your apps in any way (it shouldn't), the workaround for IntelliJ IDEA is to disable idea_rt
launcher agent by adding idea.no.launcher=true
into idea.properties
(Help
| Edit Custom Properties...
). The workaround will take effect on the next restart of the IDE.
I don't recommend disabling IntelliJ IDEA launcher agent, though. It's used for such features as graceful shutdown (Exit button), thread dumps, workarounds a problem with too long command line exceeding OS limits, etc. Losing these features just for the sake of hiding the harmless message is probably not worth it, but it's up to you.

The Facebook API watches for the FB._apiKey so you can watch for this before calling your own application of the API with something like:
window.fbAsyncInit = function() {
FB.init({
//...your init object
});
function myUseOfFB(){
//...your FB API calls
};
function FBreadyState(){
if(FB._apiKey) return myUseOfFB();
setTimeout(FBreadyState, 100); // adjust time as-desired
};
FBreadyState();
};
Not sure this makes a difference but in my case--because I wanted to be sure the UI was ready--I've wrapped the initialization with jQuery's document ready (last bit above):
$(document).ready(FBreadyState);
Note too that I'm NOT using async = true to load Facebook's all.js, which in my case seems to be helping with signing into the UI and driving features more reliably.
You could use id in (select id from ...) or id in (select id from ...)
e.g. instead of non-working
from Person p where p.name="Joe"
union
from Person p join p.children c where c.name="Joe"
you could do
from Person p
where p.id in (select p1.id from Person p1 where p1.name="Joe")
or p.id in (select p2.id from Person p2 join p2.children c where c.name="Joe");
At least using MySQL, you will run into performance problems with it later, though. It's sometimes easier to do a poor man's join on two queries instead:
// use set for uniqueness
Set<Person> people = new HashSet<Person>((List<Person>) query1.list());
people.addAll((List<Person>) query2.list());
return new ArrayList<Person>(people);
It's often better to do two simple queries than one complex one.
EDIT:
to give an example, here is the EXPLAIN output of the resulting MySQL query from the subselect solution:
mysql> explain
select p.* from PERSON p
where p.id in (select p1.id from PERSON p1 where p1.name = "Joe")
or p.id in (select p2.id from PERSON p2
join CHILDREN c on p2.id = c.parent where c.name="Joe") \G

Your query looks fine, and your data and query work for me using this JsonPath parser. Also see the example queries on that page for more predicate examples.
The testing tool that you're using seems faulty. Even the examples from the JsonPath site are returning incorrect results:

ints.SetValue(10, 0);
ints.SetValue(20, 1);
ints.SetValue(10, 2);
ints.SetValue(34, 3);
ints.SetValue(113, 4);
int[] anyVariable=(int[])ints;
Then you can just use the anyVariable as your code.
You can use reversed() method for easily reverse values.
var i:Int
for i in 1..10.reversed() {
print(i)
}
The reversed() method reverse the values.
According to the documentation you can decode JPEG/PNG images.
It should be something like this:
import tensorflow as tf
filenames = ['/image_dir/img.jpg']
filename_queue = tf.train.string_input_producer(filenames)
reader = tf.WholeFileReader()
key, value = reader.read(filename_queue)
images = tf.image.decode_jpeg(value, channels=3)

It is simple. Use that function to get server timestamp as milliseconds one time only:
var getServerTime = function( cb ) {
this.db.ref( '.info/serverTimeOffset' ).once( 'value', function( snap ) {
var offset = snap.val();
// Get server time by milliseconds
cb( new Date().getTime() + offset );
});
};
Now you can use it anywhere like that:
getServerTime( function( now ) {
console.log( now );
});
According to latest Firebase documentation, you should convert your Firebase timestamp into milliseconds. So you can use estimatedServerTimeMs
variable below:
var offsetRef = firebase.database().ref(".info/serverTimeOffset");
offsetRef.on("value", function(snap) {
var offset = snap.val();
var estimatedServerTimeMs = new Date().getTime() + offset;
});
While firebase.database.ServerValue.TIMESTAMP is much more accurate, and preferable for most read/write operations, it can occasionally be useful to estimate the client's clock skew with respect to the Firebase Realtime Database's servers. You can attach a callback to the location /.info/serverTimeOffset to obtain the value, in milliseconds, that Firebase Realtime Database clients add to the local reported time (epoch time in milliseconds) to estimate the server time. Note that this offset's accuracy can be affected by networking latency, and so is useful primarily for discovering large (> 1 second) discrepancies in clock time.

Actually you do not need to use delegate keyword. Just pass lambda as parameter:
control.Invoke((MethodInvoker)(() => {this.Text = "Hi"; }));
Aside from the excellent list by madgnome, I would add a duplicate code detector that is based off the command line (but is free):
To show a problem is NP complete, you need to:
In other words, given some information C
, you can create a polynomial time algorithm V
that will verify for every possible input X
whether X
is in your domain or not.
Prove that the problem of vertex covers (that is, for some graph G
, does it have a vertex cover set of size k
such that every edge in G
has at least one vertex in the cover set?) is in NP:
our input X
is some graph G
and some number k
(this is from the problem definition)
Take our information C
to be "any possible subset of vertices in graph G
of size k
"
Then we can write an algorithm V
that, given G
, k
and C
, will return whether that set of vertices is a vertex cover for G
or not, in polynomial time.
Then for every graph G
, if there exists some "possible subset of vertices in G
of size k
" which is a vertex cover, then G
is in NP
.
Note that we do not need to find C
in polynomial time. If we could, the problem would be in `P.
Note that algorithm V
should work for every G
, for some C
. For every input there should exist information that could help us verify whether the input is in the problem domain or not. That is, there should not be an input where the information doesn't exist.
This involves getting a known NP-complete problem like SAT, the set of boolean expressions in the form:
(A or B or C) and (D or E or F) and ...
where the expression is satisfiable, that is there exists some setting for these booleans, which makes the expression true.
Then reduce the NP-complete problem to your problem in polynomial time.
That is, given some input X
for SAT
(or whatever NP-complete problem you are using), create some input Y
for your problem, such that X
is in SAT if and only if Y
is in your problem. The function f : X -> Y
must run in polynomial time.
In the example above, the input Y
would be the graph G
and the size of the vertex cover k
.
For a full proof, you'd have to prove both:
that X
is in SAT
=> Y
in your problem
and Y
in your problem => X
in SAT
.
marcog's answer has a link with several other NP-complete problems you could reduce to your problem.
Footnote: In step 2 (Prove it is NP-hard), reducing another NP-hard (not necessarily NP-complete) problem to the current problem will do, since NP-complete problems are a subset of NP-hard problems (that are also in NP).
Using the Intl object (or via toLocaleString) is somewhat problematic, but it can be made precise using the formatToParts method and manually putting the parts in order, e.g.
function formatDate(date = new Date()) {_x000D_
let {day, month, year} = new Intl.DateTimeFormat('en', {_x000D_
day:'2-digit',_x000D_
month: 'short',_x000D_
year: 'numeric'_x000D_
}).formatToParts(date).reduce((acc, part) => {_x000D_
if (part.type != 'literal') {_x000D_
acc[part.type] = part.value;_x000D_
}_x000D_
return acc;_x000D_
}, Object.create(null));_x000D_
return `${day}-${month}-${year}`;_x000D_
}_x000D_
_x000D_
console.log(formatDate());
_x000D_
Using reduce on the array returned by formatToParts trims out the literals and creates an object with named properties that is then assigned to variables and finally formatted.
This function doesn't always work nicely for languages other than English though as the short month name may have punctuation.

First you download ODBC driver psqlodbc_09_01_0200-x64.zip then you installed it.After that go to START->Program->Administrative tools then you select Data Source ODBC then you double click on the same after that you select PostgreSQL 30 then you select configure then you provide proper details such as db name user Id host name password of the same database in this way you will configured your DSN connection.After That you will check SSL should be allow .
Then you go on next tab system DSN then you select ADD tabthen select postgreSQL_ANSI_64X ODBC after you that you have created PostgreSQL ODBC connection.
You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start()
. The headers will be sent automatically when any HTML is output.
Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.
Move the session_start()
to the top of your document :
<?php session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php'; // more PHP code here.
I'm using this one
function getBackgroundImageUrl($element) {
if (!($element instanceof jQuery)) {
$element = $($element);
}
var imageUrl = $element.css('background-image');
return imageUrl.replace(/(url\(|\)|'|")/gi, ''); // Strip everything but the url itself
}
