I am trying to obtain a handle on one of the views in the Action Bar
I will assume that you mean something established via android:actionLayout
in your <item>
element of your <menu>
resource.
I have tried calling findViewById(R.id.menu_item)
To retrieve the View
associated with your android:actionLayout
, call findItem()
on the Menu
to retrieve the MenuItem
, then call getActionView()
on the MenuItem
. This can be done any time after you have inflated the menu resource.
Another one, if by any chance you're using Dropbox, check for Conflicted
in file names, do a search in your repo and delete all those conflicted files.
This may have happened if you have moved the files around.
The Connection for controluser as defined in your configuration failed, right after:
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'you_password';
node-gyp requires old Python 2 - link
If you don't have it installed - check other answers about installing windows-build-tools.
If you are like me and have both old and new Python versions installed, chances are that node-gyp tries to use Python 3. And that results in the following SyntaxError: invalid syntax
error.
I found an article about having two Python versions installed. And they recommend renaming Python 2.* executable to python2.exe
- link.
So it looks like node-gyp is expecting to find old Python 2 executable renamed. Hence the error message:
...
gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2
...
Once I renamed C:\Python27\python.exe
to C:\Python27\python2.exe
it worked without errors.
Of course, both C:\Python27\
and C:\Python39\
have to be in PATH variable. And no need in setting old Python version in npm config. Your default Python still will be the new one.

You should be using event.currentTarget. React is mirroring the difference between currentTarget (element the event is attached to) and target (the element the event is currently happening on). Since this is a mouse event, type-wise the two could be different, even if it doesn't make sense for a click.

I think it has to do with your second element in storbinary
. You are trying to open file
, but it is already a pointer to the file you opened in line file = open(local_path,'rb')
. So, try to use ftp.storbinary("STOR " + i, file)
.
I have found a fairly simple way to do this.
Initially, through your Anaconda Prompt, you can follow the steps in this official Tensorflow site - here. You have to follow the steps as is, no deviation.
Later, you open the Anaconda Navigator. In Anaconda Navigator, go to Applications On --- section. Select the drop down list, after following above steps you must see an entry - tensorflow into it. Select tensorflow and let the environment load.
Then, select Jupyter Notebook in this new context, and install it, let the installation get over.
After that you can run the Jupyter notebook like the regular notebook in tensorflow environment.
found it myself ;) adding:

disable the default back button.

That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null
or undefined
here, so don't complain about the possibility of it being null
or undefined
." Sometimes the type checker is unable to make that determination itself.
It is explained here:
A new
!
post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operationx!
produces a value of the type ofx
withnull
andundefined
excluded. Similar to type assertions of the forms<T>x
andx as T
, the!
non-null assertion operator is simply removed in the emitted JavaScript code.
I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.
In order to send data from child component create property decorated with output() in child component and in the parent listen to the created event. Emit this event with new values in the payload when ever it needed.
@Output() public eventName:EventEmitter = new EventEmitter();
to emit this event:
this.eventName.emit(payloadDataObject);
Even without looking at assembly, the most obvious reason is that /= 2
is probably optimized as >>=1
and many processors have a very quick shift operation. But even if a processor doesn't have a shift operation, the integer division is faster than floating point division.
Edit: your milage may vary on the "integer division is faster than floating point division" statement above. The comments below reveal that the modern processors have prioritized optimizing fp division over integer division. So if someone were looking for the most likely reason for the speedup which this thread's question asks about, then compiler optimizing /=2
as >>=1
would be the best 1st place to look.
On an unrelated note, if n
is odd, the expression n*3+1
will always be even. So there is no need to check. You can change that branch to
{
n = (n*3+1) >> 1;
count += 2;
}
So the whole statement would then be
if (n & 1)
{
n = (n*3 + 1) >> 1;
count += 2;
}
else
{
n >>= 1;
++count;
}
FWIR, if authentication is only username & pw, add remote server ip address to known_hosts like ssh-keyscan -H 192.168.1.162 >> ~/.ssh/known_hosts

I use the following function extensively. As pointed out above, using other methods can sometimes give inaccurate results due to used range updates, gaps in the data, or different columns having different row counts.
Example of use:
lastRow=FindRange("Sheet1","A1:A1000")
would return the last occupied row number of the entire range. You can specify any range you want from single columns to random rows, eg FindRange("Sheet1","A100:A150")
Public Function FindRange(inSheet As String, inRange As String) As Long
Set fr = ThisWorkbook.Sheets(inSheet).Range(inRange).find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious)
If Not fr Is Nothing Then FindRange = fr.row Else FindRange = 0
End Function
Another neat option is to use the Directive
as an element and not as an attribute.
@Directive({
selector: 'app-directive'
})
export class InformativeDirective implements AfterViewInit {
@Input()
public first: string;
@Input()
public second: string;
ngAfterViewInit(): void {
console.log(`Values: ${this.first}, ${this.second}`);
}
}
And this directive can be used like that:
<app-someKindOfComponent>
<app-directive [first]="'first 1'" [second]="'second 1'">A</app-directive>
<app-directive [first]="'First 2'" [second]="'second 2'">B</app-directive>
<app-directive [first]="'First 3'" [second]="'second 3'">C</app-directive>
</app-someKindOfComponent>`
Simple, neat and powerful.

There is a (somewhat) related question on StackOverflow:
Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeeze
d or sliced into a 2D array.
More generally, the reason for the Exception
TypeError: Invalid dimensions for image data
is shown here: matplotlib.pyplot.imshow()
needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!
You can easily check this with (these checks are done by imshow
, this function is only meant to give a more specific message in case it's not a valid input):
from __future__ import print_function
import numpy as np
def valid_imshow_data(data):
data = np.asarray(data)
if data.ndim == 2:
return True
elif data.ndim == 3:
if 3 <= data.shape[2] <= 4:
return True
else:
print('The "data" has 3 dimensions but the last dimension '
'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
''.format(data.shape[2]))
return False
else:
print('To visualize an image the data must be 2 dimensional or '
'3 dimensional, not "{}".'
''.format(data.ndim))
return False
In your case:
>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False
The np.asarray
is what is done internally by matplotlib.pyplot.imshow
so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list
) it's necessary.
In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()
import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0) # or axis=1
plt.imshow(a)
plt.show()
or just use something that accepts 1D arrays like plot
:
a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

I was calling my onClick
wrong, which caused this error. So I changed
android:onClick="@{listener.onDogClicked()}"
to
android:onClick="@{listener::onDogClicked}"
Just add the line in you file,
import 'rxjs/Rx';
It will import bunch of dependencies.Tested in angular 5
Here is the solution I found:
Go to SQL Server Management, Disable Memory Shared, TCP/IP and Pipes named.
Restart the server and try again.

tt1.setText(firebaseauth.getCurrentUser().getDisplayName());//username of logged in user.
TextView tt = (TextView) headerview.findViewById(R.id.textView_emailid);
tt.setText(firebaseauth.getCurrentUser().getEmail()); //email id of logged in user.
final ImageView img1 = (ImageView) headerview.findViewById(R.id.imageView_userimage);

}
});
I have made this code by myself with some logic...Its 100% working.....pls do upvote my ans.
The textview and imageview are from @layout/nav_header_main.xml
Using conda install scipy instead of pip solved the problem for me!
Serial is not included with Python. It is a package that you'll need to install separately.
Since you have pip installed you can install serial from the command line with:
pip install pyserial
Or, you can use a Windows installer from here. It looks like you're using Python 3 so click the installer for Python 3.
Then you should be able to import serial as you tried before.
I am using a Cursor so I can not use the DiffUtils as proposed in the popular answers. In order to make it work for me I am disabling animations when the list is not idle. This is the extension that fixes this issue:
fun RecyclerView.executeSafely(func : () -> Unit) {
if (scrollState != RecyclerView.SCROLL_STATE_IDLE) {
val animator = itemAnimator
itemAnimator = null
func()
itemAnimator = animator
} else {
func()
}
}
Then you can update your adapter like that
list.executeSafely {
adapter.updateICursor(newCursor)
}
If I'm not using any category then how can I use this code? Actually, I want to use this code for custom post type.
This is valid YAML:
jobs:
- name: A
schedule: "0 0/5 * 1/1 * ? *"
type: mongodb.cluster
config:
host: mongodb://localhost:27017/admin?replicaSet=rs
minSecondaries: 2
minOplogHours: 100
maxSecondaryDelay: 120
- name: B
schedule: "0 0/5 * 1/1 * ? *"
type: mongodb.cluster
config:
host: mongodb://localhost:27017/admin?replicaSet=rs
minSecondaries: 2
minOplogHours: 100
maxSecondaryDelay: 120
Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.
You don't want git revert
. That undoes a previous commit. You want git checkout
to get git's version of the file from master.
git checkout -- filename.txt
In general, when you want to perform a git operation on a single file, use -- filename
.
2020 Update
Git introduced a new command git restore
in version 2.23.0
. Therefore, if you have git version 2.23.0+
, you can simply git restore filename.txt
- which does the same thing as git checkout -- filename.txt
. The docs for this command do note that it is currently experimental.
If you are running the
mvn spring-boot:run
from the command line, make sure you are in the directory that contains the pom.xml file. Otherwise, you will run into the No plugin found for prefix 'spring-boot' in the current project and in the plugin groups error.
If you are using CocoaPods and you want to disable Bitcode for all libraries, use the following command in the Podfile
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
end
I faced the same problem, even if I was working on my home wifi connection, without any proxy requirements.
My project was created at c:\users\<>\Workspace\Project\
When I went to above location and ran
mvn clean install
I got below error:
[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its de
endencies could not be resolved: Failed to read artifact descriptor for org.apa
he.maven.plugins:maven-clean-plugin:jar:2.5: Could not transfer artifact org.ap
che.maven.plugins:maven-clean-plugin:pom:2.5 from/to central (https://repo.mave
.apache.org/maven2)
It took me entire day to try ways and means to crack this, but the solution in my case, was damn simple.
I moved my project to non-user specific location, at E:\Workspace\Project\
This has done wonders for me!

I have head around lots of solutions and none of them works perfectly. I've used variation of solutions available in my project which is here as below. Please use this code inside class where you are initialising toolbar and drawer layout.
getSupportFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
@Override
public void onBackStackChanged() {
if (getSupportFragmentManager().getBackStackEntryCount() > 0) {
drawerFragment.mDrawerToggle.setDrawerIndicatorEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);// show back button
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onBackPressed();
}
});
} else {
//show hamburger
drawerFragment.mDrawerToggle.setDrawerIndicatorEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
drawerFragment.mDrawerToggle.syncState();
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
drawerFragment.mDrawerLayout.openDrawer(GravityCompat.START);
}
});
}
}
});

You've mixed different approaches how to include legacy vendor modules. This is how I'd tackle it:
dist
Most modules link the dist
version in the main
field of their package.json
. While this is useful for most developers, for webpack it is better to alias the src
version because this way webpack is able to optimize dependencies better (e.g. when using the DedupePlugin
).
// webpack.config.js
module.exports = {
...
resolve: {
alias: {
jquery: "jquery/src/jquery"
}
}
};
However, in most cases the dist
version works just fine as well.
ProvidePlugin
to inject implicit globalsMost legacy modules rely on the presence of specific globals, like jQuery plugins do on $
or jQuery
. In this scenario you can configure webpack, to prepend var $ = require("jquery")
everytime it encounters the global $
identifier.
var webpack = require("webpack");
...
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
})
]
this
Some legacy modules rely on this
being the window
object. This becomes a problem when the module is executed in a CommonJS context where this
equals module.exports
. In this case you can override this
with the imports-loader.
Run npm i imports-loader --save-dev
and then
module: {
loaders: [
{
test: /[\/\\]node_modules[\/\\]some-module[\/\\]index\.js$/,
loader: "imports-loader?this=>window"
}
]
}
The imports-loader can also be used to manually inject variables of all kinds. But most of the time the ProvidePlugin
is more useful when it comes to implicit globals.
There are modules that support different module styles, like AMD, CommonJS and legacy. However, most of the time they first check for define
and then use some quirky code to export properties. In these cases, it could help to force the CommonJS path by setting define = false
.
module: {
loaders: [
{
test: /[\/\\]node_modules[\/\\]some-module[\/\\]index\.js$/,
loader: "imports-loader?define=>false"
}
]
}
If you don't care about global variables and just want legacy scripts to work, you can also use the script-loader. It executes the module in a global context, just as if you had included them via the <script>
tag.
noParse
to include large distsWhen there is no AMD/CommonJS version of the module and you want to include the dist
, you can flag this module as noParse
. Then webpack will just include the module without parsing it, which can be used to improve the build time. This means that any feature requiring the AST, like the ProvidePlugin
, will not work.
module: {
noParse: [
/[\/\\]node_modules[\/\\]angular[\/\\]angular\.js$/
]
}
Firstly, I would try a non-secure websocket connection. So remove one of the s
's from the connection address:
conn = new WebSocket('ws://localhost:8080');
If that doesn't work, then the next thing I would check is your server's firewall settings. You need to open port 8080
both in TCP_IN
and TCP_OUT
.
it sometimes occurs when we use a custom adapter in any activity of fragment . and we return null object i.e null view so the activity gets confused which view to load , so that is why this exception occurs
Whenever you want to extend the properties of User.Identity with any additional properties like the question above, add these properties to the ApplicationUser class first like so:
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
// Your Extended Properties
public long? OrganizationId { get; set; }
}
Then what you need is to create an extension method like so (I create mine in an new Extensions folder):
namespace App.Extensions
{
public static class IdentityExtensions
{
public static string GetOrganizationId(this IIdentity identity)
{
var claim = ((ClaimsIdentity)identity).FindFirst("OrganizationId");
// Test for null to avoid issues during local testing
return (claim != null) ? claim.Value : string.Empty;
}
}
}
When you create the Identity in the ApplicationUser class, just add the Claim -> OrganizationId like so:
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here => this.OrganizationId is a value stored in database against the user
userIdentity.AddClaim(new Claim("OrganizationId", this.OrganizationId.ToString()));
return userIdentity;
}
Once you added the claim and have your extension method in place, to make it available as a property on your User.Identity, add a using statement on the page/file you want to access it:
in my case: using App.Extensions;
within a Controller and @using. App.Extensions
withing a .cshtml View file.
EDIT:
What you can also do to avoid adding a using statement in every View is to go to the Views folder, and locate the Web.config file in there.
Now look for the <namespaces>
tag and add your extension namespace there like so:
<add namespace="App.Extensions" />
Save your file and you're done. Now every View will know of your extensions.
You can access the Extension Method:
var orgId = User.Identity.GetOrganizationId();
len(response['Items'])
will give you the count of the filtered rows
where,
fe = Key('entity').eq('tesla')
response = table.scan(FilterExpression=fe)
For cases like the one you described, I found this to work. It's relatively short and sweet:
let attributedString = NSMutableAttributedString(string: "follow the yellow brick road") //can essentially come from a textField.text as well (will need to unwrap though)
let text = "follow the yellow brick road"
let str = NSString(string: text)
let theRange = str.rangeOfString("yellow")
attributedString.addAttribute(NSForegroundColorAttributeName, value: UIColor.yellowColor(), range: theRange)
Add this line at the top:
"xmlns:app="http://schemas.android.com/apk/res-auto"
and then use:
app:showasaction="ifroom"
I have handled back and Home button in Navigation Drawer like

I had the same error. Eventually I got this notice that a plugin was out of date:
After I updated, the problem went away.
Node comes with npm installed so you should have a version of npm. However, npm gets updated more frequently than Node does, so you'll want to make sure it's the latest version.
Try
sudo npm install npm -g
Try changing the following lines with new values
$cfg['Servers'][$i]['user'] = 'NEW_USERNAME';
$cfg['Servers'][$i]['password'] = 'NEW_PASSWORD';
Updated due to the absence of the above lines in the config file

There are two keystores, keep that in mind!!!
For those of you who visit this page looking for further clarification on this error, in my case the activity making the call to the fragment needed to have 2 implements in this case, like this:

I had the same problem for days until I noticed (how could I look at it and not read the code :-(..) that config.inc.php
is calling config-db.php
** MySql Server version: 5.7.5-m15
** Apache/2.4.10 (Ubuntu)
** phpMyAdmin 4.2.9.1deb0.1
/etc/phpmyadmin/config-db.php:
$dbuser='yourDBUserName';
$dbpass='';
$basepath='';
$dbname='phpMyAdminDBName';
$dbserver='';
$dbport='';
$dbtype='mysql';
Here you need to define your username, password, dbname and others that are showing empty' use default unless you changed their configuration.
That solved the issue for me.
U hope it helps you.

Please download the correct version of Oracle Client like Oracle Client 11.2 32-Bit; which resolved the problem for me.
The main issue that is mentioned by others but not called out enough is that -O3
does nothing at all in Swift (and never has) so when compiled with that it is effectively non-optimised (-Onone
).
Option names have changed over time so some other answers have obsolete flags for the build options. Correct current options (Swift 2.2) are:
-Onone // Debug - slow
-O // Optimised
-O -whole-module-optimization //Optimised across files
Whole module optimisation has a slower compile but can optimise across files within the module i.e. within each framework and within the actual application code but not between them. You should use this for anything performance critical)
You can also disable safety checks for even more speed but with all assertions and preconditions not just disabled but optimised on the basis that they are correct. If you ever hit an assertion this means that you are into undefined behaviour. Use with extreme caution and only if you determine that the speed boost is worthwhile for you (by testing). If you do find it valuable for some code I recommend separating that code into a separate framework and only disabling the safety checks for that module.
0) go to phpmyadmin don't select any db
1) Click "Privileges". You'll see all the users on MySQL's privilege tables.
2) Check the user "root" whose Host value is localhost, and click the "Edit Privileges" icon.
3) In the "Change password" field, click "Password" and enter a new password.
4) Retype the password to confirm. Then click "Go" to apply the settings.
The solutions here are old and now deprecated: https://github.com/uuidjs/uuid#deep-requires-now-deprecated
Use this:
npm install uuid
//add these lines to your code
const { v4: uuidv4 } = require('uuid');
var your_uuid = uuidv4();
console.log(your_uuid);
There are cases where you don't need to put @Transactional annotation to your service method, like integration testing. I was getting this org.hibernate.LazyInitializationException when testing a method that just selects from database, which did not need to be transactional. The entity class I try to load has a lazy fetch relation that caused this
@OneToMany(mappedBy = "parent", fetch = FetchType.LAZY)
private List<Item> items;
so I ended up adding the @Transactional to only to the test method.
@Test
@Transactional
public void verifySomethingTestSomething() {
Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.
I had a opened record set of the post that was created by:
Set RecSet = Conn.Execute()
This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...
RecSet.Close
Set RecSet = Nothing
...everything worked just fine.
So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.
I had this problem when trying to run 'npm install' in a Terminal window which had been opened before installing Node.js.
Opening a new Terminal window (i.e. bash session) worked. (Presumably this provided the correct environment variables for npm to run correctly.)
Just set Integrated Security=False
and it will work ,according to a comment difference between True
and False
is:
True
ignoresUser ID
andPassword
if provided and uses those of the running process,SSPI(Security Support Provider Interface )
it will use them if provided which is why MS prefers this. They are equivalent in that they use the same security mechanism to authenticate but that is it.
app.factory('persistObject', function () {
var persistObject = [];
function set(objectName, data) {
persistObject[objectName] = data;
}
function get(objectName) {
return persistObject[objectName];
}
return {
set: set,
get: get
}
});
Fill it with data like this
persistObject.set('objectName', data);
Get the object data like this
persistObject.get('objectName');
The variables/parameters within the class
definition requires { get; set; }
I was using like a variable declaration (stupid of me, because it was working for other scenarios) without
{ get; set; }
Because of which, whatever I send from the JavaScript, it was not being received in the Action method. It was always getting null or empty model.
Once the {get; set;} is added, it worked like charm.
I hope it helps someone who is coming from VB6 style of programming line.
I had the same issue. Tried all the above answers. It was actually complained about a .dll file. I clean the project in Visual Studio but the .dll file still remains, so I deleted in manually from the bin folder and it worked.
When you install third-party extensions you need to make sure that all the compilation parameters match:
Common glitches includes:
php.ini
file (that's typical with bundles); the right path is shown in phpinfo()
.Not being able to see the startup errors; those should show up in Apache logs, but you can also use the command line to diagnose it, e.g.:
php -d display_startup_errors=1 -d error_reporting=-1 -d display_errors -c "C:\Path\To\php.ini" -m
If everything's right you should see sqlsrv
in the command output and/or phpinfo()
(depending on what SAPI you're configuring):
[PHP Modules]
bcmath
calendar
Core
[...]
SPL
sqlsrv
standard
[...]
You can/should set your parameter to value to DBNull.Value;
if (variable == "")
{
cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = DBNull.Value;
}
else
{
cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = variable;
}
Or you can leave your server side set to null and not pass the param at all.
This is because findViewById()
searches in the activity_main
layout, while the button is located in the fragment's layout fragment_main
.
Move that piece of code in the onCreateView()
method of the fragment:
//...
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onButtonClick((Button) view);
}
});
Notice that now you access it through rootView
view:
Button buttonClick = (Button)rootView.findViewById(R.id.button);
otherwise you would get again NullPointerException.
Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.
<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
This worked perfectly fine.
</xsl:if>
gyp ERR! configure error gyp ERR! stack Error: Can't find Python executable "python", you can set the PYT HON env variable.
This means the Python env. variable should point to the executable python file, in my case:
SET PYTHON=C:\work\_env\Python27\python.exe
I also had this error. It worked normally after I clean up the cookies.
I have found a way to use JSONP
method in $http
directly and with support of params
in the config object:
params = {
'a': b,
'callback': 'JSON_CALLBACK'
};
$http({
url: url,
method: 'JSONP',
params: params
})
If you have assigned the slice to a variable and want to set using the variable as in the following:
df2 = df[df['A'] > 2]
df2['B'] = value
And you do not want to use Jeffs solution because your condition computing df2
is to long or for some other reason, then you can use the following:
df.loc[df2.index.tolist(), 'B'] = value
df2.index.tolist()
returns the indices from all entries in df2, which will then be used to set column B in the original dataframe.

Sometimes You just open too much applications in Windows and make the gradle have no enough memory to start the daemon process.So when you come across with this situation,you can just close some applications such as Chrome and so on. Then restart your android studio.

if your error is same like mine..just do this
right click on your table in sqlserver object explorer,choose properties in lower left corner in general option there is a connection block with server and connection specification.in your web config for datasource=. or local choose name specified in server in properties..
The server directive has to be in the http directive. It should not be outside of it.
Incase if you need detailed information, refer this.
It can also be used as below:
from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)
Here is how i resolved this:
1 - create a Field Variable like: private Menu mMenuItem;
2 - override the method invalidateOptionsMenu():
@Override
public void invalidateOptionsMenu() {
super.invalidateOptionsMenu();
}
3 - call the method invalidateOptionsMenu()
in your onCreate()
4 - add mMenuItem = menu
in your onCreateOptionsMenu(Menu menu)
like this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.webview_menu, menu);
mMenuItem = menu;
return super.onCreateOptionsMenu(menu);
}
5 - in the method onOptionsItemSelected(MenuItem item)
change the icon you want like this:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.R.id.action_settings:
mMenuItem.getItem(0).setIcon(R.drawable.ic_launcher); // to change the fav icon
//Toast.makeText(this, " " + mMenuItem.getItem(0).getTitle(), Toast.LENGTH_SHORT).show(); <<--- this to check if the item in the index 0 is the one you are looking for
return true;
}
return super.onOptionsItemSelected(item);
}
In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.olddirectory"
android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
</Preference>
</PreferenceScreen>
I needed the following instead:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.newdirectory"
android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>
Correcting the path names fixed the problem.
The immediate cause of the problem is that the JDBC driver has attempted to read from a network Socket that has been closed by "the other end".
This could be due to a few things:
If the remote server has been configured (e.g. in the "SQLNET.ora" file) to not accept connections from your IP.
If the JDBC url is incorrect, you could be attempting to connect to something that isn't a database.
If there are too many open connections to the database service, it could refuse new connections.
Given the symptoms, I think the "too many connections" scenario is the most likely. That suggests that your application is leaking connections; i.e. creating connections and then failing to (always) close them.
For anyone else looking to do what the original poster is asking, please consider to use fragments instead the way Kevin said. Here is an excellent tutorial on how to do that:
https://github.com/codepath/android_guides/wiki/Fragment-Navigation-Drawer
If you choose to instead use activities instead of fragments you are going to run into the problem of the nav drawer being re-created every time you navigate to a new activity. This results in an ugly/slow rendering of the nav drawer each time.
Add your JDK's /bin folder to the PATH
environmental variable. You can do this under System settings > Environmental variables, or via CLI:
set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
Close and reopen your CLI window
If you are using Lodash library below is the way to set a dynamic variable in the angular scope.
To set the value in the angular scope.
_.set($scope, the_string, 'life.meaning')
To get the value from the angular scope.
_.get($scope, 'life.meaning')
I am late for the answer but I think this is another solution which is not mentioned here so posting.
Step 1: Make a xml of menu which you want to add like I have to add a filter action on my action bar so I have created a xml filter.xml. The main line to notice is android:orderInCategory this will show the action icon at first or last wherever you want to show. One more thing to note down is the value, if the value is less then it will show at first and if value is greater then it will show at last.
filter.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" >
<item
android:id="@+id/action_filter"
android:title="@string/filter"
android:orderInCategory="10"
android:icon="@drawable/filter"
app:showAsAction="ifRoom" />
</menu>
Step 2: In onCreate() method of fragment just put the below line as mentioned, which is responsible for calling back onCreateOptionsMenu(Menu menu, MenuInflater inflater) method just like in an Activity.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
Step 3: Now add the method onCreateOptionsMenu which will be override as:
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.filter, menu); // Use filter.xml from step 1
}
Step 4: Now add onOptionsItemSelected method by which you can implement logic whatever you want to do when you select the added action icon from actionBar:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.action_filter){
//Do whatever you want to do
return true;
}
return super.onOptionsItemSelected(item);
}
Best way to do this, just call CallingFragmentName fragment = (CallingFragmentName) viewPager .getAdapter() .instantiateItem(viewPager, viewPager.getCurrentItem()); It will re-instantiate your calling Fragment, so that it will not throw null pointer exception and call any method of that fragment.

Try to wrap wsdlLocation in wsdlUrls

It seemed that a lot of dependencies were incorrect.
A good place to look for the correct dependencies is the Maven Repository website.
I had the similar issue. its resolved for me with a simple command.
lsnrctl start
The Network Adapter exception is caused because:
lsnrctl
utility.Try to start the listener using the command prompt:

without the quotes and press Enter.Exit
and press Enter.Hope it helps.
When installing Python 3.4 the "Add python.exe to Path" came up unselected. Re-installed with this selected and problem resolved.

Personally i prefer to do ajax in wordpress the same way that i would do ajax on any other site. I create a processor php file that handles all my ajax requests and just use that URL. So this is, because of htaccess not exactly possible in wordpress so i do the following.
1.in my htaccess file that lives in my wp-content folder i add this below what's already there
<FilesMatch "forms?\.php$">
Order Allow,Deny
Allow from all
</FilesMatch>
In this case my processor file is called forms.php - you would put this in your wp-content/themes/themeName folder along with all your other files such as header.php footer.php etc... it just lives in your theme root.
2.) In my ajax code i can then use my url like this
$.ajax({
url:'/wp-content/themes/themeName/forms.php',
data:({
someVar: someValue
}),
type: 'POST'
});
obviously you can add in any of your before, success or error type things you'd like ...but yea this is (i believe) the easier way to do it because you avoid all the silliness of telling wordpress in 8 different places what's going to happen and this also let's you avoid doing other things you see people doing where they put js code on the page level so they can dip into php where i prefer to keep my js files separate.
Use substring and concatenate:
if(str.length() > 50)
strOut = str.substring(0,7) + "...";
you have to create an entry inside res/menu,
override onCreateOptionsMenu
and inflate it
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.yourentry, menu);
return true;
}
an entry for the menu could be:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/action_cart"
android:icon="@drawable/cart"
android:orderInCategory="100"
android:showAsAction="always"/>
</menu>

The problem was I have 2 instances of Mysql installed and I didn't know the password for both instances.Just check if port 80 is used by any of the programs. This is what I did
1.Quit Skype because it was using port 80.(Please check if port 80 is used by any other program).
2.Search for Mysql services in task manager and stop it.
3.Now delete all the related mysql files.Make sure you delete all the files.
4.Reinstall
First:
chmod 777 ./MigrateNshell.sh
Then:
./MigrateNshell.sh
Or, add your program to a directory recognized in your $PATH variable. Example: Path Variable Example
Which will then allow you to call your program without ./
I spent my whole day today investigating this problem and none of the answers helped. Here is my scenario. The WebApplicationInitializer types in my case are inside jar files. we have a multi-module gradle web project where each module is packaged as a jar and included in the web artifact. The problem is that Apache tomcat's classloader is not looking for the implementations of WebApplicationIntializer in WEB-INF/lib instead its looking for those types directly under WEB-INF/classes folder.
Here is what I ended up doing for anyone who faces this problem in future.
I implemented a ServletContainerInitializer myself and added that class name to META-INF/services/javax.servlet.ServletContainerInitializer
In the implementation, I copied the code from SpringServletContainerIntializer and used reflections to find the classes implementing a CustomWebApplicationInitializer interface, I did not make use of spring's WebApplicationInitializer interface to avoid any conflicts. Basically I have the same contract as WebApplicationInitializer with a different name. Now on startup, my container initializer is called and I delegated the call to all my CustomWebApplicationInitializers.
Based on my search I also found that the loader used for tomcat can be updated to have it search in WEB-INF/lib but I have little control over the tomcat I deploy my app to so went with the above solution. Hope this helps someone.
For future reference, this can also happen if npm is down. That's how I found this question. Wish the first npm task was a server status check so there was a clearer error message.
Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
if you further face any difficulty then you need to provide more information about your web site and sql server .
egrep -v "Nopaging the limit is|keyword to remove is"
First, check if you have internet permission in Manifest file.
<uses-permission android:name="android.permission.INTERNET" />
You can then add following code in onCreate() or initialize() method-
final WebView webview = (WebView) rootView.findViewById(R.id.webview);
webview.setWebViewClient(new MyWebViewClient());
webview.getSettings().setBuiltInZoomControls(false);
webview.getSettings().setSupportZoom(false);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.getSettings().setAllowFileAccess(true);
webview.getSettings().setDomStorageEnabled(true);
webview.loadUrl(URL);
And write a class to handle callbacks of webview -
public class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//your handling...
return super.shouldOverrideUrlLoading(view, url);
}
}
in same class, you can also use other important callbacks such as -
- onPageStarted()
- onPageFinished()
- onReceivedSslError()
Also, you can add "SwipeRefreshLayout" to enable swipe refresh and refresh the webview.
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipeRefreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="@+id/webview"
android:layout_width="match_parent"

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document
You can do like that In Kotlin If you need kotlin code in the future
val myUri = getImageUri(applicationContext, myBitmap!!)
val finalFile = File(getRealPathFromURI(myUri))
fun getImageUri(inContext: Context, inImage: Bitmap): Uri {
val bytes = ByteArrayOutputStream()
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes)
val path = MediaStore.Images.Media.insertImage(inContext.contentResolver, inImage, "Title", null)
return Uri.parse(path)
}
fun getRealPathFromURI(uri: Uri): String {
val cursor = contentResolver.query(uri, null, null, null, null)
cursor!!.moveToFirst()
val idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA)
return cursor.getString(idx)
}
Answering my own question about 2 or something years later here but...
It uses a protocol extension so you can do it without any extra code for all classes.
/*
Prerequisites
-------------
- In IB set the view's class to the type hook up any IBOutlets
- In IB ensure the file's owner is blank
*/
public protocol CreatedFromNib {
static func createFromNib() -> Self?
static func nibName() -> String?
}
extension UIView: CreatedFromNib { }
public extension CreatedFromNib where Self: UIView {
public static func createFromNib() -> Self? {
guard let nibName = nibName() else { return nil }
guard let view = NSBundle.mainBundle().loadNibNamed(nibName, owner: nil, options: nil).last as? Self else { return nil }
return view
}
public static func nibName() -> String? {
guard let n = NSStringFromClass(Self.self).componentsSeparatedByString(".").last else { return nil }
return n
}
}
// Usage:
let myView = MyView().createFromNib()
This is most easiest way to let NPM do everything for you

In my case, I got this no cipher suites in common
error because I've loaded a p12

sudo brew is no longer an option so if you install with brew at this point you're going to get 2 really obnoxious things:
A: it likes to install into /usr/local/opts
or according to this, /usr/local/shared. This isn't a big deal at first but i've had issues with node PATH especially when I installed lint.
B: you're kind of stuck with sudo commands until you either uninstall and install it this way or you can get the stack from Bitnami
I recommend this method over the stack option because it's ready to go if you have multiple projects. If you go with the premade MEAN stack you'll have to set up virtual hosts in httpd.conf (more of a pain in this stack than XAMPP)plust the usual update your extra/vhosts.conf and /etc/hosts for every additional project, unless you want to repoint and restart your server when you get done updatading things.
I've searched the minimal solution possible to do PHP + WebSockets during hours, until I found this article:
Super simple PHP WebSocket example
It doesn't require any third-party library.
Here is how to do it: create a index.html
containing this:
<html>
<body>
<div id="root"></div>
<script>
var host = 'ws://<<<IP_OF_YOUR_SERVER>>>:12345/websockets.php';
var socket = new WebSocket(host);
socket.onmessage = function(e) {
document.getElementById('root').innerHTML = e.data;
};
</script>
</body>
</html>
and open it in the browser, just after you have launched php websockets.php
in the command-line (yes, it will be an event loop, constantly running PHP script), with this websockets.php
file.
The await
inside your asynchronous method is trying to come back to the UI thread.
Since the UI thread is busy waiting for the entire task to complete, you have a deadlock.
Moving the async call to Task.Run()
solves the issue.
Because the async call is now running on a thread pool thread, it doesn't try to come back to the UI thread, and everything therefore works.
Alternatively, you could call StartAsTask().ConfigureAwait(false)
before awaiting the inner operation to make it come back to the thread pool rather than the UI thread, avoiding the deadlock entirely.
Short And working Solution :
Follow Simple Steps :
Step 1 : Override onSaveInstanceState
state in respective fragment. And remove super method from it.
@Override
public void onSaveInstanceState(Bundle outState) {
}
Step 2 : Use CommitAllowingStateLoss();
instead of commit();
while fragment operations.
fragmentTransaction.commitAllowingStateLoss();
The problem must be with the value Model.Id which is null. You can confirm by assigning a value, e.g
@{
var blogPostId = 1;
}
If the error disappers, then u need to make sure that your model Id has a value before passing it to the view
if you are using emulator to run your app for local server. mention the local ip
as 10.0.2.2
and have to give Internet permission into your app :
<uses-permission android:name="android.permission.INTERNET" />
You can use java.util.regex.Pattern with the CASE_INSENSITIVE flag for case insensitive matching:
Pattern.compile(Pattern.quote(strptrn), Pattern.CASE_INSENSITIVE).matcher(str1).find();
Did you update the project (right-click on the project, "Maven" > "Update project...")? Otherwise, you need to check if pom.xml
contains the necessary slf4j dependencies, e.g.:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.7.0</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.0</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.0</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>
add below code to activity_main.xml file:
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="buttonClick"
android:text="@string/button" />
and just add the below method to the MainActivity.java file:
public void buttonClick(View view){
Intent i = new Intent(getApplicationContext()SendPhotos.class);
startActivity(i);
}
I had to set "Copy Local" in the Reference Properties to False, then back to True. Doing this added the Private True setting to the .csproj file.
<Reference Include="Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> <HintPath>..\packages\Microsoft.Web.Infrastructure.1.0.0.0\lib\net40\Microsoft.Web.Infrastructure.dll</HintPath>
<Private>True</Private>
</Reference>
I had assumed this was already set, since the "Copy Local" showed as True.
There is no such thing as array constant in Go.
Quoting from the Go Language Specification: Constants:
There are boolean constants, rune constants, integer constants, floating-point constants, complex constants, and string constants. Rune, integer, floating-point, and complex constants are collectively called numeric constants.
A Constant expression (which is used to initialize a constant) may contain only constant operands and are evaluated at compile time.
The specification lists the different types of constants. Note that you can create and initialize constants with constant expressions of types having one of the allowed types as the underlying type. For example this is valid:
func main() {
type Myint int
const i1 Myint = 1
const i2 = Myint(2)
fmt.Printf("%T %v\n", i1, i1)
fmt.Printf("%T %v\n", i2, i2)
}
Output (try it on the Go Playground):
main.Myint 1
main.Myint 2
If you need an array, it can only be a variable, but not a constant.
I recommend this great blog article about constants: Constants
try use this code it works for me. by the way it came from this site https://github.com/eternicode/bootstrap-datepicker/issues/464 .
$('#datepicker').datepicker().on('show', function () {
var modal = $('#datepicker').closest('.modal');
var datePicker = $('body').find('.datepicker');
if (!modal.length) {
$(datePicker).css('z-index', 'auto');
return;
}
var zIndexModal = $(modal).css('z-index');
$(datePicker).css('z-index', zIndexModal + 1);
});
With fscanf
read the file until you encounter ';'
or \n
, then you can just skip it with fscang(f, "%*c")
.
int main()
{
char str[128];
int result;
FILE* f = fopen("test.txt", "r");
...
do {
result = fscanf(f, "%127[^;\n]", str);
if(result == 0)
{
result = fscanf(f, "%*c");
}
else
{
//whatever you want to do with your value
printf("%s\n", str);
}
} while(result != EOF);
return 0;
}
Good solutions explained pretty well here. But Here is one more.
Create your own CustomContextWrapper
class extending ContextWrapper
and use it to change Locale setting for the complete application.
Here is a GIST with usage.
And then call the CustomContextWrapper
with saved locale identifier e.g. 'hi'
for Hindi language in activity lifecycle method attachBaseContext
. Usage here:
@Override
protected void attachBaseContext(Context newBase) {
// fetch from shared preference also save the same when applying. Default here is en = English
String language = MyPreferenceUtil.getInstance().getString("saved_locale", "en");
super.attachBaseContext(MyContextWrapper.wrap(newBase, language));
}
This one just worked for me....
The error message displayed is:
“# 1146 – Table ‘phpmyadmin.pma_table_uiprefs’ doesn’t exist“
on your programme files,locate the configuration file config.inc.php
phpmyadmin
Then trace the file $Cfg ['Servers'] [$ i] ['table_uiprefs'] = ‘pma_table_uiprefs’;
and replace it to the code : $cfg ['Servers'] [$ i] ['pma__table_uiprefs'] = ‘pma__table_uiprefs’;
restart your XAMMP and start localhost
solved.
Please check the directory path whether exists or not. This error comes up if the folder doesn't exists from where you are running the command. Probably you have executed a remove command from same path in command line.

<dependency>

slf4j-log4j12
is the log4j binding for slf4j
you dont need to add another log4j dependency.
Added
Provide the log4j configuration in log4j.properties
and add it to your class path. There are sample configurations here
or you can change your binding to
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.1</version>
</dependency>
if you are configuring slf4j due to some dependencies requiring it.
What worked for me was adding:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public void onBackPressed() {
finish();
}
to TheRelevantActivity.java
and now it is working as expected
and yeah don't forget to add:
getSupportActionbar.setDisplayHomeAsUpEnabled(true);
in onCreate()
method
You haven't specify version in your maven dependency file may be thats why it is not picking the latest jar
As well as you need another deppendency with slf4j-log4j12
artifact id.
Include this in your pom file
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.6</version>
</dependency>
Let me know if error is still not resolved
I also recomend you to see this link
I had to embed my $location.path()
statement like this because my digest was still running:
function routeMe(data) {
var waitForRender = function () {
if ($http.pendingRequests.length > 0) {
$timeout(waitForRender);
} else {
$location.path(data);
}
};
$timeout(waitForRender);
}
If you really want a bruteforce algorithm, don't save any big list in the memory of your computer, unless you want a slow algorithm that crashes with a MemoryError.
You could try to use itertools.product like this :
from string import ascii_lowercase
from itertools import product
charset = ascii_lowercase # abcdefghijklmnopqrstuvwxyz
maxrange = 10
def solve_password(password, maxrange):
for i in range(maxrange+1):
for attempt in product(charset, repeat=i):
if ''.join(attempt) == password:
return ''.join(attempt)
solved = solve_password('solve', maxrange) # This worked for me in 2.51 sec
itertools.product(*iterables)
returns the cartesian products of the iterables you entered.
[i for i in product('bar', (42,))]
returns e.g. [('b', 42), ('a', 42), ('r', 42)]
The repeat
parameter allows you to make exactly what you asked :
[i for i in product('abc', repeat=2)]
Returns
[('a', 'a'),
('a', 'b'),
('a', 'c'),
('b', 'a'),
('b', 'b'),
('b', 'c'),
('c', 'a'),
('c', 'b'),
('c', 'c')]
Note:
You wanted a brute-force algorithm so I gave it to you. Now, it is a very long method when the password starts to get bigger because it grows exponentially (it took 62 sec to find the word 'solved').
This worked for me. :)
sudo keytool -importcert -file filename.cer -alias randomaliasname -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit
I had the same situation and I found a way around with a bit of engineering as follows - -
You have to have your method in parent class without any parameter and use - -
Class<? extends Person> cl = this.getClass(); // inside parent class
Now, with 'cl' you can access all child class fields with their name and initialized values by using - -
cl.getDeclaredFields(); cl.getField("myfield"); // and many more
In this situation your 'this' pointer will reference your child class object if you are calling parent method through your child class object.
Another thing you might need to use is Object obj = cl.newInstance();
Let me know if still you got stucked somewhere.
I've recently ren into this issue with Commodo cert I bought on ssls.com and I've had 3 files:
domain-name.ca-bundle domain-name.crt and domain-name.p7b
I've had to set it up on Nginx and this is the command I ran:
cat domain-name.ca-bundle domain-name.crt > commodo-ssl-bundle.crt
I then used commodo-ssl-bundle.crt inside the Nginx config file and works like a charm.
If you're using Python 2.5, this won't work, but for people using 2.6 or 2.7, try
from __future__ import print_function
print("abcd", end='')
print("efg")
results in
abcdefg
For those using 3.x, this is already built-in.
I use the actionBarSherlock,
after we set supportActionBar.setHomeButtonEnabled(true);
we can override the onMenuItemSelected method:
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
int itemId = item.getItemId();
switch (itemId) {
case android.R.id.home:
toggle();
// Toast.makeText(this, "home pressed", Toast.LENGTH_LONG).show();
break;
}
return true;
}
I hope this work for you ~~~ good luck
Use positioning. The following worked for me... (Horizontally and Vertically Centered)
With zoom to the center of the image (image fills the div):
div{
display:block;
overflow:hidden;
width: 70px;
height: 70px;
position: relative;
}
div img{
min-width: 70px;
min-height: 70px;
max-width: 250%;
max-height: 250%;
top: -50%;
left: -50%;
bottom: -50%;
right: -50%;
position: absolute;
}
Without zoom to the center of the image (image does not fill the div):
div{
display:block;
overflow:hidden;
width: 100px;
height: 100px;
position: relative;
}
div img{
width: 70px;
height: 70px;
top: 50%;
left: 50%;
bottom: 50%;
right: 50%;
position: absolute;
}
You will need to change the configure port of either Apache or Nginx. After you do this you will need to restart the reconfigured servers, using the 'service' command you used.
Apache
Edit
sudo subl /etc/apache2/ports.conf
and change the 80 on the following line to something different :
Listen 80
If you just change the port or add more ports here, you will likely also have to change the VirtualHost statement in
sudo subl /etc/apache2/sites-enabled/000-default.conf
and change the 80 on the following line to something different :
<VirtualHost *:80>
then restart by :
sudo service apache2 restart
Nginx
Edit
/etc/nginx/sites-enabled/default
and change the 80 on the following line :
listen 80;
then restart by :
sudo service nginx restart
public static String abcBase36(int i) {
char[] ALPHABET = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ".toCharArray();
int quot = i / 36;
int rem = i % 36;
char letter = ALPHABET[rem];
if (quot == 0) {
return "" + letter;
} else {
return abcBase36(quot - 1) + letter;
}
}
On Windows 10 Add this to your Path:
%APPDATA%\npm
This references the folder ~/AppData/Roaming/npm
[Assumes that you have already run npm install -g grunt-cli
]
They have wrapped most stuff need to solve your problem, one of the tests looks like this:
String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";
StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));
String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);
These two schools are not really excluding.
Here is the scenario where you simply have to use
Task.Run(() => AsyncOperation()).Wait();
or something like
AsyncContext.Run(AsyncOperation);
I have a MVC action that is under database transaction attribute. The idea was (probably) to roll back everything done in the action if something goes wrong. This does not allow context switching, otherwise transaction rollback or commit is going to fail itself.
The library I need is async as it is expected to run async.
The only option. Run it as a normal sync call.
I am just saying to each its own.
Since you are using WebSocket, spender is correct. After recieving the initial data from the WebSocket, you need to send the handshake message from the C# server before any further information can flow.
HTTP/1.1 101 Web Socket Protocol Handshake
Upgrade: websocket
Connection: Upgrade
WebSocket-Origin: example
WebSocket-Location: something.here
WebSocket-Protocol: 13
Something along those lines.
You can do some more research into how WebSocket works on w3 or google.
Here is a protocol specifcation: http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-76#section-1.3
List of working examples:
I face the same problem and changing
$cfg['Servers'][$i]['host'] = 'localhost';
to
$cfg['Servers'][$i]['host'] = '127.0.0.1';
Solved this issue.
I ran into this issue too. It confused me until I realized what was wrong:
You have this:
include /etc/nginx/mime.types;
default_type application/octet-stream;
You want this:
default_type application/octet-stream;
include /etc/nginx/mime.types;
there appears to either be a bug in nginx or a deficiency in the docs (this could be the intended behavior, but it is odd)
The port was changed to 9001 in 5.4, just changing the port from 9000 to 9001 in the nginx conf and in php-fpm configuration worked for me.
import java.util.*;
public class arrayList {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
ArrayList<String > x=new ArrayList<>();
//inserting element
x.add(sc.next());
x.add(sc.next());
x.add(sc.next());
x.add(sc.next());
x.add(sc.next());
//to show element
System.out.println(x);
//converting arraylist to stringarray
String[]a=x.toArray(new String[x.size()]);
for(String s:a)
System.out.print(s+" ");
}
}
The first server block in the nginx config is the default for all requests that hit the server for which there is no specific server block.
So in your config, assuming your real domain is REAL.COM, when a user types that in, it will resolve to your server, and since there is no server block for this setup, the server block for FAKE.COM, being the first server block (only server block in your case), will process that request.
This is why proper Nginx configs have a specific server block for defaults before following with others for specific domains.
# Default server
server {
return 404;
}
server {
server_name domain_1;
[...]
}
server {
server_name domain_2;
[...]
}
etc
It seems some users are a bit confused by this example and think it is limited to a single conf file etc.
Please note that the above is a simple example for the OP to develop as required.
I personally use separate vhost conf files with this as so (CentOS/RHEL):
http {
[...]
# Default server
server {
return 404;
}
# Other servers
include /etc/nginx/conf.d/*.conf;
}
/etc/nginx/conf.d/
will contain domain_1.conf, domain_2.conf... domain_n.conf which will be included after the server block in the main nginx.conf file which will always be the first and will always be the default unless it is overridden it with the default_server directive elsewhere.
The alphabetical order of the file names of the conf files for the other servers becomes irrelevant in this case.
In addition, this arrangement gives a lot of flexibility in that it is possible to define multiple defaults.
In my specific case, I have Apache listening on Port 8080 on the internal interface only and I proxy PHP and Perl scripts to Apache.
However, I run two separate applications that both return links with ":8080" in the output html attached as they detect that Apache is not running on the standard Port 80 and try to "help" me out.
This causes an issue in that the links become invalid as Apache cannot be reached from the external interface and the links should point at Port 80.
I resolve this by creating a default server for Port 8080 to redirect such requests.
http {
[...]
# Default server block for undefined domains
server {
listen 80;
return 404;
}
# Default server block to redirect Port 8080 for all domains
server {
listen my.external.ip.addr:8080;
return 301 http://$host$request_uri;
}
# Other servers
include /etc/nginx/conf.d/*.conf;
}
As nothing in the regular server blocks listens on Port 8080, the redirect default server block transparently handles such requests by virtue of its position in nginx.conf.
I actually have four of such server blocks and this is a simplified use case.

I would like to mention that, I came across the same situation when I tried adding a library into my project. All of a sudden all switch statements started to show errors!
Now I tried to remove the library which I added, even then it did not work. how ever "when I cleaned the project" all the errors just went off !
success
has been the traditional name of the success callback in jQuery, defined as an option in the ajax call. However, since the implementation of $.Deferreds
and more sophisticated callbacks, done
is the preferred way to implement success callbacks, as it can be called on any deferred
.
For example, success:
$.ajax({
url: '/',
success: function(data) {}
});
For example, done:
$.ajax({url: '/'}).done(function(data) {});
The nice thing about done
is that the return value of $.ajax
is now a deferred promise that can be bound to anywhere else in your application. So let's say you want to make this ajax call from a few different places. Rather than passing in your success function as an option to the function that makes this ajax call, you can just have the function return $.ajax
itself and bind your callbacks with done
, fail
, then
, or whatever. Note that always
is a callback that will run whether the request succeeds or fails. done
will only be triggered on success.
For example:
function xhr_get(url) {
return $.ajax({
url: url,
type: 'get',
dataType: 'json',
beforeSend: showLoadingImgFn
})
.always(function() {
// remove loading image maybe
})
.fail(function() {
// handle request failures
});
}
xhr_get('/index').done(function(data) {
// do stuff with index data
});
xhr_get('/id').done(function(data) {
// do stuff with id data

An important benefit of this in terms of maintainability is that you've wrapped your ajax mechanism in an application-specific function. If you decide you need your $.ajax
call to operate differently in the future, or you use a different ajax method, or you move away from jQuery, you only have to change the xhr_get
definition (being sure to return a promise or at least a done
method, in the case of the example above). All the other references throughout the app can remain the same.
There are many more (much cooler) things you can do with $.Deferred
, one of which is to use pipe
to trigger a failure on an error reported by the server, even when the $.ajax
request itself succeeds. For example:
function xhr_get(url) {
return $.ajax({
url: url,
type: 'get',
dataType: 'json'
})
.pipe(function(data) {
return data.responseCode != 200 ?
$.Deferred().reject( data ) :
data;
})
.fail(function(data) {
if ( data.responseCode )
console.log( data.responseCode );
});
}
xhr_get('/index').done(function(data) {
// will not run if json returned from ajax has responseCode other than 200
});
Read more about $.Deferred
here: http://api.jquery.com/category/deferred-object/
NOTE: As of jQuery 1.8, pipe
has been deprecated in favor of using then
in exactly the same way.
//add urlencode to your address $address = urlencode("technopark, Trivandrun, kerala,India"); $region = "IND"; $json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=$region"); echo $json; $decoded = json_decode($json); print_r($decoded);
Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:
storageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
),
getAlbumName()
);
The picture doesn't go to the album. To do this, you need to call a scan:
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}

So basic idea is to have a div (with display none) containing items to print. Now on click of a button do not print to entire body but just that particular div. Faced lots of issues while printing a div (part of HTML) using window.print(). Used below method and it works seamlessly in edge, chrome and Mozilla for me, let see if it help you too.
function printDiv(id) {
var contents = document.getElementById(id).innerHTML;
var frame1 = document.createElement('iframe');
frame1.name = "frame1";
frame1.style.position = "absolute";
frame1.style.top = "-1000000px";
document.body.appendChild(frame1);
var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document : frame1.contentDocument;
frameDoc.document.open();
frameDoc.document.write("<html><head>\n\n " +
"<style type=\"text/css\" media=\"print\">\n " +
"@@page\n {\n " +
"size: auto; /* auto is the initial value */\n " +
"margin: 10mm; /* this affects the margin in the printer settings */\n " +
" }\n\n html\n {\n " +
" background-color: #FFFFFF;\n " +
" }\n\n body\n " +
" { font-family:\"Times New Roman\", Times, serif;\n " +
" border: none ;\n " +
" margin: 0; /* margin you want for the content */\n " +
" }\n .table {\n width: 100%;\n " +
" max-width: 100%;\n margin-bottom: 20px;\n " +
" border-collapse: collapse;\n " +
" background-color: transparent;\n display: table;\n " +
" }\n .table-bordered {\n " +
" border: 1px solid #ccc;\n }\n tr {\n " +
" display: table-row;\n vertical-align: inherit;\n " +
" border-color: inherit;\n padding:15px;\n }\n " +
" .table-bordered tr td {border: 1px solid #ccc!important; padding:15px!important;}\n " +
" </style><title></title></head><body>".concat(contents, "</body>"));
frameDoc.document.close();
setTimeout(function () {
window.frames["frame1"].focus();
window.frames["frame1"].print();
document.body.removeChild(frame1);
}, 500);
return false;
}
Call this like
<a href="#" onclick="javascript:printDiv('divwithcontenttoprint')"> Print </a>
In KitKat and above, you could use evaluateJavascript
method on webview
wvbrowser.evaluateJavascript(
"(function() { return ('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>'); })();",
new ValueCallback<String>() {
@Override
public void onReceiveValue(String html) {
Log.d("HTML", html);
// code here
}
});
See this answer for more examples
Construct the first parameter as an instance of Action
, e.g.
var inputID = 123;
var col = new BlockingDataCollection();
var task = Task.Factory.StartNew(
() => CheckFiles(inputID, col),
cancelCheckFile.Token,
TaskCreationOptions.LongRunning,
TaskScheduler.Default);
Another poossible solution is based on the array_search()
function. You need to use PHP 5.5.0 or higher.
$userdb=Array
(
(0) => Array
(
(uid) => '100',
(name) => 'Sandra Shush',
(url) => 'urlof100'
),
(1) => Array
(
(uid) => '5465',
(name) => 'Stefanie Mcmohn',
(pic_square) => 'urlof100'
),
(2) => Array
(
(uid) => '40489',
(name) => 'Michael',
(pic_square) => 'urlof40489'
)
);
$key = array_search(40489, array_column($userdb, 'uid'));
echo ("The key is: ".$key);
//This will output- The key is: 2
The function array_search()
has two arguments. The first one is the value that you want to search. The second is where the function should search. The function array_column()
gets the values of the elements which key is 'uid'
.
So you could use it as:
array_search('breville-one-touch-tea-maker-BTM800XL', array_column($products, 'slug'));
or, if you prefer:
// define function
function array_search_multidim($array, $column, $key){
return (array_search($key, array_column($array, $column)));
}
// use it
array_search_multidim($products, 'slug', 'breville-one-touch-tea-maker-BTM800XL');
The original example(by xfoxawy) can be found on the DOCS.
The array_column()
page.
Update
Due to Vael comment I was curious, so I made a simple test to meassure the performance of the method that uses array_search
and the method proposed on the accepted answer.
I created an array which contained 1000 arrays, the structure was like this (all data was randomized):
[
{
"_id": "57fe684fb22a07039b3f196c",
"index": 0,
"guid": "98dd3515-3f1e-4b89-8bb9-103b0d67e613",
"isActive": true,
"balance": "$2,372.04",
"picture": "http://placehold.it/32x32",
"age": 21,
"eyeColor": "blue",
"name": "Green",
"company": "MIXERS"
},...
]
I ran the search test 100 times searching for different values for the name field, and then I calculated the mean time in milliseconds. Here you can see an example.
Results were that the method proposed on this answer needed about 2E-7 to find the value, while the accepted answer method needed about 8E-7.
Like I said before both times are pretty aceptable for an application using an array with this size. If the size grows a lot, let's say 1M elements, then this little difference will be increased too.
Update II
I've added a test for the method based in array_walk_recursive
which was mentionend on some of the answers here. The result got is the correct one. And if we focus on the performance, its a bit worse than the others examined on the test. In the test, you can see that is about 10 times slower than the method based on array_search
. Again, this isn't a very relevant difference for the most of the applications.
Update III
Thanks to @mickmackusa for spotting several limitations on this method:
GitHub could make this a lot better with minimal work. Here is a work-around.
I think you want something more like
[Your Title](your-project-name/tree/master/your-subfolder)
or to point to the README itself

{
Bitmap c = this.DrawMandel();
Button btn = pea as Button;
Graphics gr = btn.CreateGraphics();
gr.DrawImage(b, 150, 200);
}

As SLF4J Manual states
The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks, such as java.util.logging, logback and log4j.
and
The warning will disappear as soon as you add a binding to your class path.
So you should choose which binding do you want to use.
NoOp binding (slf4j-nop)
Binding for NOP, silently discarding all logging.
Check fresh version at https://search.maven.org/search?q=g:org.slf4j%20AND%20a:slf4j-nop&core=gav
Simple binding (slf4j-simple)
outputs all events to System.err. Only messages of level INFO and higher are printed. This binding may be useful in the context of small applications.
Check fresh version at https://search.maven.org/search?q=g:org.slf4j%20AND%20a:slf4j-simple&core=gav
Bindings for the logging frameworks (java.util.logging, logback, log4j)
You need one of these bindings if you are going to write log to a file.
See description and instructions at https://www.slf4j.org/manual.html#projectDep
My opinion
I would recommend Logback because it's a successor to the log4j project.
Check latest version of the binding for it at https://search.maven.org/search?q=g:ch.qos.logback%20AND%20a:logback-classic&core=gav
You get console output out of the box but if you need to write logs into file just put FileAppender
configuration to the src/main/resources/logback.xml
or to the src/test/resources/logback-test.xml
just like this:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>logs/logs.log</file>
<encoder>
<pattern>%date %level [%thread] %logger{10} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
<logger level="DEBUG" name="com.myapp"/>
</configuration>
(See detailed description in manual: https://logback.qos.ch/manual/configuration.html)
I also had the same problem and it tooks me several hours to figured out.
I just changed 'config' to 'cookie'
$cfg['Servers'][$i]['auth_type'] = 'config';
I needed to change the menu icon for the fragment. I altered Charles’s answer to this question a bit for the fragment:
private Menu top_menu;
//...
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
setHasOptionsMenu(true);
//...
rootview = inflater.inflate(R.layout.first_content,null);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.fragment_menu, menu);
this.top_menu = menu;
}
// my procedure
private void updateIconMenu() {
if(top_menu!= null) {
MenuItem nav_undo = top_menu.findItem(R.id.action_undo);
nav_undo.setIcon( R.drawable.back);
}
}
i like this simple one:
function randstr(prefix)
{
return Math.random().toString(36).replace('0.',prefix || '');
}
since id should (though not must) start with a letter, i'd use it like this:
let div_id = randstr('youtube_div_');
some example values:
youtube_div_4vvbgs01076
youtube_div_1rofi36hslx
youtube_div_i62wtpptnpo
youtube_div_rl4fc05xahs
youtube_div_jb9bu85go7
youtube_div_etmk8u7a3r9
youtube_div_7jrzty7x4ft
youtube_div_f41t3hxrxy
youtube_div_8822fmp5sc8
youtube_div_bv3a3flv425
Express version:
"dependencies": {
"body-parser": "^1.19.0",
"express": "^4.17.1"
}
Optional parameter are very much handy, you can declare and use them easily using express:
app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
console.log("category Id: "+req.params.cId);
console.log("product ID: "+req.params.pId);
if (req.params.batchNo){
console.log("Batch No: "+req.params.batchNo);
}
});
In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'
Now I can call with only categoryId and productId or with all three-parameter.

What you could do is something like this (pseudocode):
<container table>
<tr>
<td>
<"300px" table>
<td>
<fixed layout table>
Basically, split up the table into two tables and have it contained by another table.
You can try this one it is short :)
SystemClock.sleep(7000);
It will sleep for 7 sec look at documentation
Try This with Capital Letters, Small Letters, Numeric(s) and Special Characters
function generatePassword($_len) {
$_alphaSmall = 'abcdefghijklmnopqrstuvwxyz'; // small letters
$_alphaCaps = strtoupper($_alphaSmall); // CAPITAL LETTERS
$_numerics = '1234567890'; // numerics
$_specialChars = '`~!@#$%^&*()-_=+]}[{;:,<.>/?\'"\|'; // Special Characters
$_container = $_alphaSmall.$_alphaCaps.$_numerics.$_specialChars; // Contains all characters
$password = ''; // will contain the desired pass
for($i = 0; $i < $_len; $i++) { // Loop till the length mentioned
$_rand = rand(0, strlen($_container) - 1); // Get Randomized Length
$password .= substr($_container, $_rand, 1); // returns part of the string [ high tensile strength ;) ]
}
return $password; // Returns the generated Pass
}
Let's Say we need 10 Digit Pass
echo generatePassword(10);

yes the above answer is correct, but it's not secure, you can login root user directlyinto phpMyAdmin
.
If you want to create new user with password and give grant permission, execute the below command in MySQL on terminal, Login into your server on terminal,
# mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO 'user-name'@'%' IDENTIFIED BY 'password' REQUIRE NONE WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;
Residuum did provide a correct answer to how you should get shell exec to find your script, but in regards to security, there are a couple of points.
I would imagine you don't want your shell script to be in your web root, as it would be visible to anyone with web access to your server.
I would recommend moving the shell script to outside of the webroot
<?php
$tempFolder = '/tmp';
$webRootFolder = '/var/www';
$scriptName = 'myscript.sh';
$moveCommand = "mv $webRootFolder/$scriptName $tempFolder/$scriptName";
$output = shell_exec($moveCommand);
?>
In regards to the:
i added www-data ALL=(ALL) NOPASSWD:ALL to /etc/sudoers works
You can modify this to only cover the specific commands in your script which require sudo. Otherwise, if none of the commands in your sh script require sudo to execute, you don't need to do this at all anyway.
Try running the script as the apache user (use the su command to switch to the apache user) and if you are not prompted for sudo or given permission denied, etc, it'll be fine.
ie:
sudo su apache (or www-data)
cd /var/www
sh ./myscript
Also... what brought me here was that I wanted to run a multi line shell script using commands that are dynamically generated. I wanted all of my commands to run in the same shell, which won't happen using multiple calls to shell_exec(). The answer to that one is to do it like Jenkins - create your dynamically generated multi line of commands, put it in a variable, save it to a file in a temp folder, execute that file (using shell_exec in() php as Jenkins is Java), then do whatever you want with the output, and delete the temp file
... voila
As I landed up here due to the question. Few of the solutions from above don't solve the problem. After a few lookups, I found a solution on the internet that provided if a node is present in the current viewport where the answers I tried solves of it's present in the body or not.
function isInViewport(element) {
const rect = element.getBoundingClientRect();
return (
rect.top >= 0 &&
rect.left >= 0 &&
rect.bottom <= (window.innerHeight || document.documentElement.clientHeight) &&
rect.right <= (window.innerWidth || document.documentElement.clientWidth)
);
}
isInViewport(document.querySelector('.selector-i-am-looking-for'));
The snippet is taken from HERE to keep as a backup as the links may be unavailable after some time. Check the link for an explanation.
And, didn't intend to post in the comment, as in most cases, they are ignored.
if($var == "abc" || $var == "def" || ...)
{
echo "true";
}
Using "Or" instead of "And" would help here, i think
the best solution when you are perform on navigation drawer
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.setGroupVisible(0,false);
return true;
}
You are getting the error because $ret
is not an array.
To get rid of the error, at the start of your function, define it with this line: $ret = array();
It appears that the get_tags() call is returning nothing, so the foreach is not run, which means that $ret isn't defined.
If it's an object method, you need to pass the object to CallObjectMethod
:
jobject result = env->CallObjectMethod(obj, messageMe, jstr);
What you were doing was the equivalent of jstr.messageMe()
.
Since your is a void method, you should call:
env->CallVoidMethod(obj, messageMe, jstr);
If you want to return a result, you need to change your JNI signature (the ()V
means a method of void
return type) and also the return type in your Java code.
What Jeremiah said, plus the compiler issues the warning because the production:
*src ="anotherstring";
says: take the address of "anotherstring" -- "anotherstring" IS a char pointer -- and store that pointer indirect through src (*src = ... ) into the first char of the string "abcdef..." The warning might be baffling because there is nowhere in your code any mention of any integer: the warning seems nonsensical. But, out of sight behind the curtain, is the rule that "int" and "char" are synonymous in terms of storage: both occupy the same number of bits. The compiler doesn't differentiate when it issues the warning that you are storing into an integer. Which, BTW, is perfectly OK and legal but probably not exactly what you want in this code.

This is an older question, but there is actually an answer to this in the PowerShell documentation. I had the same problem, and for once RTFM actually solved it. Almost.
Documentation for the -File parameter states that "In rare cases, you might need to provide a Boolean value for a switch parameter. To provide a Boolean value for a switch parameter in the value of the File parameter, enclose the parameter name and value in curly braces, such as the following: -File .\Get-Script.ps1 {-All:$False}"
I had to write it like this:
PowerShell.Exe -File MyFile.ps1 {-SomeBoolParameter:False}
So no '$' before the true/false statement, and that worked for me, on PowerShell 4.0
Why parentheses?
Here is the quote from the book programming in scala.
Another important idea illustrated by this example will give you insight into why arrays are accessed with parentheses in Scala. Scala has fewer special cases than Java. Arrays are simply instances of classes like any other class in Scala. When you apply parentheses surrounding one or more values to a variable, Scala will transform the code into an invocation of a method named apply on that variable. So greetStrings(i) gets transformed into greetStrings.apply(i). Thus accessing an element of an array in Scala is simply a method call like any other. This principle is not restricted to arrays: any application of an object to some arguments in parentheses will be transformed to an apply method call. Of course this will compile only if that type of object actually defines an apply method. So it's not a special case; it's a general rule.
Here are a few examples how to pull certain element (first elem in this case) using functional programming style.
// Create a multdimension Array
scala> val a = Array.ofDim[String](2, 3)
a: Array[Array[String]] = Array(Array(null, null, null), Array(null, null, null))
scala> a(0) = Array("1","2","3")
scala> a(1) = Array("4", "5", "6")
scala> a
Array[Array[String]] = Array(Array(1, 2, 3), Array(4, 5, 6))
// 1. paratheses
scala> a.map(_(0))
Array[String] = Array(1, 4)
// 2. apply
scala> a.map(_.apply(0))
Array[String] = Array(1, 4)
// 3. function literal
scala> a.map(a => a(0))
Array[String] = Array(1, 4)
// 4. lift
scala> a.map(_.lift(0))
Array[Option[String]] = Array(Some(1), Some(4))
// 5. head or last
scala> a.map(_.head)
Array[String] = Array(1, 4)
const
is for compile-time constants. You could just make it static readonly
, but that would only apply to the METRICS
variable itself (which should typically be Metrics instead, by .NET naming conventions). It wouldn't make the list immutable - so someone could call METRICS.Add("shouldn't be here");
You may want to use a ReadOnlyCollection<T>
to wrap it. For example:
public static readonly IList<String> Metrics = new ReadOnlyCollection<string>
(new List<String> {
SourceFile.LoC, SourceFile.McCabe, SourceFile.NoM,
SourceFile.NoA, SourceFile.FanOut, SourceFile.FanIn,
SourceFile.Par, SourceFile.Ndc, SourceFile.Calls });
ReadOnlyCollection<T>
just wraps a potentially-mutable collection, but as nothing else will have access to the List<T>
afterwards, you can regard the overall collection as immutable.
(The capitalization here is mostly guesswork - using fuller names would make them clearer, IMO.)
Whether you declare it as IList<string>
, IEnumerable<string>
, ReadOnlyCollection<string>
or something else is up to you... if you expect that it should only be treated as a sequence, then IEnumerable<string>
would probably be most appropriate. If the order matters and you want people to be able to access it by index, IList<T>
may be appropriate. If you want to make the immutability apparent, declaring it as ReadOnlyCollection<T>
could be handy - but inflexible.
Your regex pattern needs to be in delimiters:
$numpattern="/^([0-9]+)$/";
Try phoneNumber.setVisibility(View.GONE);
It doesn't apply to this particular code example, but as Google food, since I got the same error message:
<script>document.write('<script src="…"></script>');</script>
will give this error but
<script>document.write('<script src="…"><'+'/script>');</script>
will not.
Further explanation here: Why split the <script> tag when writing it with document.write()?
In case if String position is not fixed then by below Select statement we can get the expected output.
Table Structure ID VARCHAR2(100 BYTE) CLIENT VARCHAR2(4000 BYTE)
Data-
ID CLIENT

1002
{"IdType":"AccountNo","Id":"XXXXXXXX3521","ToPricingId":"XXXXXXXX3521","clientId":"Test-Cust","clientName":"MFX"}
Requirement - Search "ClientId" string in CLIENT column and return the corresponding value. Like From "clientId":"con-bjp" --> con-bjp(Expected output)
select CLIENT,substr(substr(CLIENT,instr(CLIENT,'"clientId":"')+length('"clientId":"')),1,instr(substr(CLIENT,instr(CLIENT,'"clientId":"')+length('"clientId":"')),'"',1 )-1) cut_str from TEST_SC;
CLIENT cut_str ----------------------------------------------------------- ---------- {"clientId":"con-bjp","clientName":"ABC","providerId":"SBS"} con-bjp {"IdType":"AccountNo","Id":"XXXXXXXX3521","ToPricingId":"XXXXXXXX3521","clientId":"Test-Cust","clientName":"MFX"} Test-Cust
To get it in a single line, try this:
$str = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ", 5)), 0, $length);
To fix it simply take Set
in place of List
for your nested object.
@OneToMany
Set<Your_object> objectList;
and don't forget to use fetch=FetchType.EAGER
it will work.
There is one more concept CollectionId
in Hibernate if you want to stick with list only.
But remind that you won't eliminate the underlaying Cartesian Product as described by Vlad Mihalcea in his answer!
In my case I kept the project on desktop and to access the desktop we need to add permission to the folder so I simply moved my project folder to C:\ directory now its working like a charm.
You may define this extension method:
public static class StringExtenstions
{
public static string InsertCharAtDividedPosition(this string str, int count, string character)
{
var i = 0;
while (++i * count + (i - 1) < str.Length)
{
str = str.Insert((i * count + (i - 1)), character);
}
return str;
}
}
And use it like:
var str = "abcdefghijklmnopqrstuvwxyz";
str = str.InsertCharAtDividedPosition(5, "-");
I use,
var text = "some/String";
text.includes("/") <-- returns bool; true if "/" exists in string, false otherwise.
I had the similar issue - could not figure out what was the reason, but I fixed it using following code. Somehow it could not focus only the blank inputs:
$('input').click(function () {
var val = $(this).val();
if (val == "") {
this.select();
}
});
Im not very familiar with the Android sdk, but it seems that the android-sdk
comes with the BouncyCastle
provider already added to the security.
What you will have to do in the PC environment is just add it manually,
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
if you have access to the policy
file, just add an entry like:
security.provider.5=org.bouncycastle.jce.provider.BouncyCastleProvider
Notice the .5
it is equal to a sequential number of the already added providers.
Interesting exercise ;-) i think i have the best solution because:
Python 2 & 3 (probably Python 1):
def rot13(s):
return ''.join([chr(ord(n) + (13 if 'Z' < n < 'n' or n < 'N' else -13)) if n.isalpha() else n for n in s])
def rot13_verbose(s):
x = []
for n in s:
if n.isalpha():
# 'n' is the 14th character in the alphabet so if a character is bigger we can subtract 13 to get rot13
ort = 13 if 'Z' < n < 'n' or n < 'N' else -13
x.append(chr(ord(n) + ort))
else:
x.append(n)
return ''.join(x)
# crazy .min version (99 characters) disclaimer: not pep8 compatible^
def r(s):return''.join([chr(ord(n)+(13if'Z'<n<'n'or'N'>n else-13))if n.isalpha()else n for n in s])
You don't need to use a subclass of Thread
to make this work - take a look at the simple example I'm posting below to see how:
from threading import Thread
from time import sleep
def threaded_function(arg):
for i in range(arg):
print("running")
sleep(1)
if __name__ == "__main__":
thread = Thread(target = threaded_function, args = (10, ))
thread.start()
thread.join()
print("thread finished...exiting")
Here I show how to use the threading module to create a thread which invokes a normal function as its target. You can see how I can pass whatever arguments I need to it in the thread constructor.
I think you need something like this: http://jsfiddle.net/BeenYoung/BXaqW/3/
$(document).ready(function() {
$("ul.opMenu li").each(function(){
$(this).click(function(){
if($(this).hasClass('opened')==false){
$('.opMenu').find('.opened').removeClass('opened').find('ul').slideUp();
$(this).addClass('opened');
$(this).find("ul").slideDown();
}else{
$(this).removeClass('opened');
$(this).find("ul").slideUp();
}
});
});
});
I hope it useful for you!
Connection object is for illustration only. The DataAdapter is the key bit:
Dim strSql As String = "SELECT EmpCode,EmpID,EmpName FROM dbo.Employee"
Dim dtb As New DataTable
Using cnn As New SqlConnection(connectionString)
cnn.Open()
Using dad As New SqlDataAdapter(strSql, cnn)
dad.Fill(dtb)
End Using
cnn.Close()
End Using
I know this is an old question, but rather than adding the snapin which is apparently unsupported, I just looked at the EMS shortcut properties and copied those commands.
The full shortcut target is:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto"
So I put the following at the start of my script and it seemed to function as expected:
. 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'
Connect-ExchangeServer -auto
Notes:
You can use a lambda with an input parameter, like so:
.Returns((string myval) => { return myval; });
Or slightly more readable:
.Returns<string>(x => x);
Very ugly but does the trick if you only want compile time info (e.g. for debugging):
auto testVar = std::make_tuple(1, 1.0, "abc");
decltype(testVar)::foo= 1;
Returns:
Compilation finished with errors:
source.cpp: In function 'int main()':
source.cpp:5:19: error: 'foo' is not a member of 'std::tuple<int, double, const char*>'
This may also can help
input="inputtext"
output="outputtext"
sed "s/$input/${output}/" inputfile > outputfile
Suppose you declared HashMap as :-
HashMap<Character,Integer> hs = new HashMap<>();
Then,key in map is of type Character data type and value of int type.Now,to get value corresponding to key irrespective of type of key,value type, syntax is :-
char temp = 'a';
if(hs.containsKey(temp)){
` int val = hs.get(temp); //val is the value corresponding to key temp
}
So, according to your question you want to get string value corresponding to a key.For this, just declare HashMap as HashMap<"datatype of key","datatype of value" hs = new HashMap<>(); Using this will make your code cleaner and also you don't have to convert the result of hs.get("my_code") to string as by default it returns value of string if at entry time one has kept value as a string.
Any API should check the validity of the every parameter of any public method before executing it:
void setPercentage(int pct, AnObject object) {
if( pct < 0 || pct > 100) {
throw new IllegalArgumentException("pct has an invalid value");
}
if (object == null) {
throw new IllegalArgumentException("object is null");
}
}
They represent 99.9% of the times errors in the application because it is asking for impossible operations so in the end they are bugs that should crash the application (so it is a non recoverable error).
In this case and following the approach of fail fast you should let the application finish to avoid corrupting the application state.
if(sessionStorage.reload) {
sessionStorage.reload = true;
// optionnal
setTimeout( () => { sessionStorage.setItem('reload', false) }, 2000);
} else {
sessionStorage.setItem('reload', false);
}
You can try this.
txt = <file_path>
txt_opn = open(txt)
print txt_opn.read()
This will give you file output.
What is Stroke
:
The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke.
https://docs.oracle.com/javase/7/docs/api/java/awt/BasicStroke.html
Note that the Stroke
setting:
Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));
is setting the line width,since BasicStroke(float width)
:
Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles.
And, it also effects other methods like Graphics2D.drawLine(int x1, int y1, int x2, int y2)
and Graphics2D.drawRect(int x, int y, int width, int height)
:
The methods of the Graphics2D interface that use the outline Shape returned by a Stroke object include draw and any other methods that are implemented in terms of that method, such as drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon.
It's fairly simple. You write values using keys and expiry times. You get values using keys. You can expire keys from the system.
Most clients follow the same rules. You can read the generic instructions and best practices on the memcached homepage.
If you really want to dig into it, I'd look at the source. Here's the header comment:
"""
client module for memcached (memory cache daemon)
Overview
========
See U{the MemCached homepage<http://www.danga.com/memcached>} for more about memcached.
Usage summary
=============
This should give you a feel for how this module operates::
import memcache
mc = memcache.Client(['127.0.0.1:11211'], debug=0)
mc.set("some_key", "Some value")
value = mc.get("some_key")
mc.set("another_key", 3)
mc.delete("another_key")
mc.set("key", "1") # note that the key used for incr/decr must be a string.
mc.incr("key")
mc.decr("key")
The standard way to use memcache with a database is like this::
key = derive_key(obj)
obj = mc.get(key)
if not obj:
obj = backend_api.get(...)
mc.set(key, obj)
# we now have obj, and future passes through this code
# will use the object from the cache.
Detailed Documentation
======================
More detailed documentation is available in the L{Client} class.

A Null pointer has the value 0. void pointer is a generic pointer introduced by ANSI. Generic pointer can hold the address of any data type.
I guess setting the position property of the #inner div to relative may also help achieve the effect. But anyways I tried the original code pasted in the Question on IE9 and latest Google Chrome and they already give the desirable effect without any modifications.
This solved my problem. You should select Properties, Right-Click, Source Control and Get Specific Version.
Your CLASSPATH
needs to know of the location of your HelloWorld
class also.
In simple terms you should append dot .
(means current directory) in the CLASSPATH
if you are running javac
and java
commands from DOS prompt.
From the documentation:
It is necessary to keep in mind that the browsers do not know how to correctly show this error.
I suspect this is what's happening, if you inspect the HTTP to-and-fro using tools such as Firebug or Live HTTP Headers (both Firefox extensions) you'll be able to see what's really going on.
you can store it as text that looks like a list and create a function that can return its data as an actual list. example:
database:
_____________________
| word | letters |
| me | '[m, e]' |
| you |'[y, o, u]' | note that the letters column is of type 'TEXT'
| for |'[f, o, r]' |
|___in___|_'[i, n]'___|
And the list compiler function (written in python, but it should be easily translatable to most other programming languages). TEXT represents the text loaded from the sql table. returns list of strings from string containing list. if you want it to return ints instead of strings, make mode equal to 'int'. Likewise with 'string', 'bool', or 'float'.
def string_to_list(string, mode):
items = []
item = ""
itemExpected = True
for char in string[1:]:
if itemExpected and char not in [']', ',', '[']:
item += char
elif char in [',', '[', ']']:
itemExpected = True
items.append(item)
item = ""
newItems = []
if mode == "int":
for i in items:
newItems.append(int(i))
elif mode == "float":
for i in items:
newItems.append(float(i))
elif mode == "boolean":
for i in items:
if i in ["true", "True"]:
newItems.append(True)
elif i in ["false", "False"]:
newItems.append(False)
else:
newItems.append(None)
elif mode == "string":
return items
else:
raise Exception("the 'mode'/second parameter of string_to_list() must be one of: 'int', 'string', 'bool', or 'float'")
return newItems
Also here is a list-to-string function in case you need it.
def list_to_string(lst):
string = "["
for i in lst:
string += str(i) + ","
if string[-1] == ',':
string = string[:-1] + "]"
else:
string += "]"
return string
As someone already pointed out how to do this with .Net Core, if your header contains a "-" or some other character .Net disallows, you can do something like:
public string Test([FromHeader]string host, [FromHeader(Name = "Content-Type")] string contentType)
{
}
I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.
In case this helps someone, this is the easiest way I found, without requiring admin rights:
C:\Users\username\R\win-library\rversion
(for example, something like: C:\Users\janebloggs\R\win-library\3.6
).Renviron
file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER
variable to be your custom path:R_LIBS_USER=C:\Users\janebloggs\R\win-library\3.6
(feel free to add comments too, with lines starting with #
)
If a .Renviron
file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile
. You can read about it in help(Startup)
.
Now it should be persistent between sessions!
Your query apparently returned all correct dates, even considering the time.
If you're still not happy with the results, give DATEDIFF a shot and look for negaive/positive results between the two dates.
Make sure your mydate
column is a datetime
type.
I reworked @givanse's solution to function as a React hook. Input is some optional event listeners, output is a functional ref (needs to be functional so the hook can re-run when/if the ref changes).
Also added in vertical/horizontal swipe threshold param, so that small motions don't accidentally trigger the event listeners, but these can be set to 0 to mimic original answer more closely.
Tip: for best performance, the event listener input functions should be memoized.
function useSwipeDetector({
// Event listeners.
onLeftSwipe,
onRightSwipe,
onUpSwipe,
onDownSwipe,
// Threshold to detect swipe.
verticalSwipeThreshold = 50,
horizontalSwipeThreshold = 30,
}) {
const [domRef, setDomRef] = useState(null);
const xDown = useRef(null);
const yDown = useRef(null);
useEffect(() => {
if (!domRef) {
return;
}
function handleTouchStart(evt) {
const [firstTouch] = evt.touches;
xDown.current = firstTouch.clientX;
yDown.current = firstTouch.clientY;
};
function handleTouchMove(evt) {
if (!xDown.current || !yDown.current) {
return;
}
const [firstTouch] = evt.touches;
const xUp = firstTouch.clientX;
const yUp = firstTouch.clientY;
const xDiff = xDown.current - xUp;
const yDiff = yDown.current - yUp;
if (Math.abs(xDiff) > Math.abs(yDiff)) {/*most significant*/
if (xDiff > horizontalSwipeThreshold) {
if (onRightSwipe) onRightSwipe();
} else if (xDiff < -horizontalSwipeThreshold) {
if (onLeftSwipe) onLeftSwipe();
}
} else {
if (yDiff > verticalSwipeThreshold) {
if (onUpSwipe) onUpSwipe();
} else if (yDiff < -verticalSwipeThreshold) {
if (onDownSwipe) onDownSwipe();
}
}
};
function handleTouchEnd() {
xDown.current = null;
yDown.current = null;
}
domRef.addEventListener("touchstart", handleTouchStart, false);
domRef.addEventListener("touchmove", handleTouchMove, false);
domRef.addEventListener("touchend", handleTouchEnd, false);
return () => {
domRef.removeEventListener("touchstart", handleTouchStart);
domRef.removeEventListener("touchmove", handleTouchMove);
domRef.removeEventListener("touchend", handleTouchEnd);
};
}, [domRef, onLeftSwipe, onRightSwipe, onUpSwipe, onDownSwipe, verticalSwipeThreshold, horizontalSwipeThreshold]);
return (ref) => setDomRef(ref);
};
This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.
DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1 nvarchar (100) = 'test1'
DECLARE @xTxt2 nvarchar (500) = 'test2'
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2

We had a similar problem in a web application, and ended up by reading the filename from the HTML <input type="file">
, and setting that in the url-encoded form in a new HTML <input type="hidden">
. Of course we had to remove the path like "C:\fakepath\" that is returned by some browsers.
Of course this does not directly answer OPs question, but may be a solution for others.
use this for open pdf file in webview
NSString *path = [[NSBundle mainBundle] pathForResource:@"mypdf" ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
UIWebView *webView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 300, 300)];
[[webView scrollView] setContentOffset:CGPointMake(0,500) animated:YES];
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"window.scrollTo(0.0, 50.0)"]];
[webView loadRequest:request];
[self.view addSubview:webView];
[webView release];
I've just spent quite some time troubleshooting this very problem. None of the proposed solutions worked. Turned out that our sysadmin by mistake assigned the same static IP to two unrelated servers belonging to different groups, but sitting on the same network. The end results were intermittently dropped vnc connections, browser that had to be refreshed several times to fetch the web page, and other strange things.
Are you sure your processor supports Intel Virtualization (VT-x) or AMD Virtualization (AMD-V)?
Here you can find Hardware-Assisted Virtualization Detection Tool ( http://www.microsoft.com/downloads/en/details.aspx?FamilyID=0ee2a17f-8538-4619-8d1c-05d27e11adb2&displaylang=en) which will tell you if your hardware supports VT-x.
Alternatively you can find your processor here: http://ark.intel.com/Default.aspx. All AMD processors since 2006 supports Virtualization.
Both will get called, first come first served. Take a look here.
$(document).ready(function(){
$("#page-title").html("Document-ready was called!");
});
$(document).ready(function(){
$("#page-title").html("Document-ready 2 was called!");
});
Output:
Document-ready 2 was called!
You may need to know the status during the file download or use credentials before making the request.
Here is an example that covers these options:
Uri ur = new Uri("http://remotehost.do/images/img.jpg");
using (WebClient client = new WebClient()) {
//client.Credentials = new NetworkCredential("username", "password");
String credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes("Username" + ":" + "MyNewPassword"));
client.Headers[HttpRequestHeader.Authorization] = $"Basic {credentials}";
client.DownloadProgressChanged += WebClientDownloadProgressChanged;
client.DownloadDataCompleted += WebClientDownloadCompleted;
client.DownloadFileAsync(ur, @"C:\path\newImage.jpg");
}
And the callback's functions implemented as follows:
void WebClientDownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
Console.WriteLine("Download status: {0}%.", e.ProgressPercentage);
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
}
void WebClientDownloadCompleted(object sender, DownloadDataCompletedEventArgs e)
{
Console.WriteLine("Download finished!");
}
(Ver 2) - Lambda notation: other possible option for handling the events
client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(delegate(object sender, DownloadProgressChangedEventArgs e) {
Console.WriteLine("Download status: {0}%.", e.ProgressPercentage);
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
});
client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(delegate(object sender, DownloadDataCompletedEventArgs e){
Console.WriteLine("Download finished!");
});
(Ver 3) - We can do better
client.DownloadProgressChanged += (object sender, DownloadProgressChangedEventArgs e) =>
{
Console.WriteLine("Download status: {0}%.", e.ProgressPercentage);
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
};
client.DownloadDataCompleted += (object sender, DownloadDataCompletedEventArgs e) =>
{
Console.WriteLine("Download finished!");
};
(Ver 4) - Or
client.DownloadProgressChanged += (o, e) =>
{
Console.WriteLine($"Download status: {e.ProgressPercentage}%.");
// updating the UI
Dispatcher.Invoke(() => {
progressBar.Value = e.ProgressPercentage;
});
};
client.DownloadDataCompleted += (o, e) =>
{
Console.WriteLine("Download finished!");
};
It is most likely that php is not in your specified path.
Try to issue the php command with the full path, for example:
C:\> "C:\Program Files\php\php.exe" -v
Please note, that this is just an example, your php installation might be in a different directory.
You can try this:
string timeexample= string.Format("{0:hh:mm:ss tt}", DateTime.Now);
you can remove hh or mm or ss or tt according your need where hh is hour in 12 hr formate, mm is minutes,ss is seconds,and tt is AM/PM.
You can't initialize arrays like this:
int cipher[Array_size][Array_size]=0;
The syntax for 2D arrays is:
int cipher[Array_size][Array_size]={{0}};
Note the curly braces on the right hand side of the initialization statement.
for 1D arrays:
int tomultiply[Array_size]={0};
In my case, I just changed
Note: This is in case of Django, so I added csrftoken
. In your case, you may not need it.
Added

to

and it worked.
Use directory-maven-plugin with directory-of goal.
Unlike other suggestions:
The plugin lets you set a property of your choice to the absolute-path of any of the project's modules. In my case I set it to the root module... In my project root pom:
<plugin>
<groupId>org.commonjava.maven.plugins</groupId>
<artifactId>directory-maven-plugin</artifactId>
<version>0.1</version>
<executions>
<execution>
<id>directories</id>
<goals>
<goal>directory-of</goal>
</goals>
<phase>initialize</phase>
<configuration>
<property>myproject.basedir</property>
<project>
<groupId>com.my.domain</groupId>
<artifactId>my-root-artifact</artifactId>
</project>
</configuration>
</execution>
</executions>
</plugin>
From then on, ${myproject.basedir} in any sub-module pom always has the path of the project root module. And of course, you can set the property to any module, not just the root...
edit (not by the author): There is a comprehensive list of IoC frameworks available at https://github.com/quozd/awesome-dotnet/blob/master/README.md#ioc:
Original answer follows.
I suppose I might be being a bit picky here but it's important to note that DI (Dependency Injection) is a programming pattern and is facilitated by, but does not require, an IoC (Inversion of Control) framework. IoC frameworks just make DI much easier and they provide a host of other benefits over and above DI.
That being said, I'm sure that's what you were asking. About IoC Frameworks; I used to use Spring.Net and CastleWindsor a lot, but the real pain in the behind was all that pesky XML config you had to write! They're pretty much all moving this way now, so I have been using StructureMap for the last year or so, and since it has moved to a fluent config using strongly typed generics and a registry, my pain barrier in using IoC has dropped to below zero! I get an absolute kick out of knowing now that my IoC config is checked at compile-time (for the most part) and I have had nothing but joy with StructureMap and its speed. I won't say that the others were slow at runtime, but they were more difficult for me to setup and frustration often won the day.
Update
I've been using Ninject on my latest project and it has been an absolute pleasure to use. Words fail me a bit here, but (as we say in the UK) this framework is 'the Dogs'. I would highly recommend it for any green fields projects where you want to be up and running quickly. I got all I needed from a fantastic set of Ninject screencasts by Justin Etheredge. I can't see that retro-fitting Ninject into existing code being a problem at all, but then the same could be said of StructureMap in my experience. It'll be a tough choice going forward between those two, but I'd rather have competition than stagnation and there's a decent amount of healthy competition out there.
Other IoC screencasts can also be found here on Dimecasts.
Besides the removal of the github messaging service, usage was often not necessary due to many githubbers communicating with- and advocating twitter.
The advantage is that there is:
It is probably no coincidence that stackoverflow doesn't allow private messaging either, to ensure full transparency. The entire messaging issue is thoroughly discussed on meta-stackoverflow here.
If you want to save it as .fig file, hgsave is the function in Matlab R2012a. In later versions, savefig may also work.
In addition to what the other replies said, if you have to parse very large files with hundreds of thousands of timestamps, date_parser
can prove to be a huge performance bottleneck, as it's a Python function called once per row. You can get a sizeable performance improvements by instead keeping the dates as text while parsing the CSV file and then converting the entire column into dates in one go:
# For a data column
df = pd.read_csv(infile, parse_dates={'mydatetime': ['date', 'time']})
df['mydatetime'] = pd.to_datetime(df['mydatetime'], exact=True, cache=True, format='%Y-%m-%d %H:%M:%S')
# For a DateTimeIndex
df = pd.read_csv(infile, parse_dates={'mydatetime': ['date', 'time']}, index_col='mydatetime')
df.index = pd.to_datetime(df.index, exact=True, cache=True, format='%Y-%m-%d %H:%M:%S')
# For a MultiIndex
df = pd.read_csv(infile, parse_dates={'mydatetime': ['date', 'time']}, index_col=['mydatetime', 'num'])
idx_mydatetime = df.index.get_level_values(0)
idx_num = df.index.get_level_values(1)
idx_mydatetime = pd.to_datetime(idx_mydatetime, exact=True, cache=True, format='%Y-%m-%d %H:%M:%S')
df.index = pd.MultiIndex.from_arrays([idx_mydatetime, idx_num])
For my use case on a file with 200k rows (one timestamp per row), that cut down processing time from about a minute to less than a second.
I was just Googling the same issue, and posted my final solution HERE. It's relevant to this question too.
You can do this easily with a div by giving it the style word-wrap: break-word
(and you may need to set its width, too).
div {
word-wrap: break-word; /* All browsers since IE 5.5+ */
overflow-wrap: break-word; /* Renamed property in CSS3 draft spec */
width: 100%;
}
However, for tables, you also need to apply: table-layout: fixed
. This means the columns widths are no longer fluid, but are defined based on the widths of the columns in the first row only (or via specified widths). Read more here.
Sample code:
table {
table-layout: fixed;
width: 100%;
}
table td {
word-wrap: break-word; /* All browsers since IE 5.5+ */
overflow-wrap: break-word; /* Renamed property in CSS3 draft spec */
}

There's no need to write a custom directive. Angular's documentation is good but not complete. In fact, there is a directive called ngRequired
, that takes an Angular expression.
<input type='email'
name='email'
ng-model='contact.email'
placeholder='[email protected]'
ng-required='!contact.phone' />
<input type='text'
ng-model='contact.phone'
placeholder='(xxx) xxx-xxxx'
ng-required='!contact.email' />
Here's a more complete example: http://jsfiddle.net/uptnx/1/

How are you? I had the same problem while i was trying connect to MSSQL Server remotely using jdbc (dbeaver on debian).
After a while, i found out that my firewall configuration was not correctly. So maybe it could help you!
Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.
Four exceptions must be configured in Windows Firewall to allow access to SQL Server:
A port exception for TCP Port 1433. In the New Inbound Rule Wizard dialog, use the following information to create a port exception: Select Port Select TCP and specify port 1433 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – TCP 1433" A port exception for UDP Port 1434. Click New Rule again and use the following information to create another port exception: Select Port Select UDP and specify port 1434 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – UDP 1434 A program exception for sqlservr.exe. Click New Rule again and use the following information to create a program exception: Select Program Click Browse to select ‘sqlservr.exe’ at this location: [C:\Program Files\Microsoft SQL Server\MSSQL11.\MSSQL\Binn\sqlservr.exe] where is the name of your SQL instance. Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule SQL – sqlservr.exe A program exception for sqlbrowser.exe Click New Rule again and use the following information to create another program exception: Select Program Click Browse to select sqlbrowser.exe at this location: [C:\Program Files\Microsoft SQL Server\90\Shared\sqlbrowser.exe]. Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule SQL - sqlbrowser.exe

Android SDK Build Tools are exactly what the name says they are; tools for building Android Applications.It is very important to use the latest build tools version (selected automatically by your IDE via the Android SDK) but the reason the old versions are left there is to support backward compatibility, that is If your projects depend on older versions of the Build Tools.
git pull origin master
worked for me. It was just about giving remote and branch name explicitly.
Suppose the data is in the B column, write in the C column the formula:
=SUBSTITUTE(B1," ","")
Copy&Paste the formula in the whole C column.
edit: using commas or semicolons as parameters separator depends on your regional settings (I have to use the semicolons). This is weird I think. Thanks to @tocallaghan and @pablete for pointing this out.
Have you tried setting the spacing to zero?
/*alternating row*/
table, tr, td, th {margin:0;border:0;padding:0;spacing:0;}
tr.rowhighlight {background-color:#f0f8ff;margin:0;border:0;padding:0;spacing:0;}
Here is one possible way. Use the exists
function to check for something unique in your util.R
code.
For example:
if(!exists("foo", mode="function")) source("util.R")
(Edited to include mode="function"
, as Gavin Simpson pointed out)
Once you are in the directory of your project.
use cd path/to/directory
then use ng g c component_name --spec=false
it automates everything and is error free
the g c
means generate component
You are not changing the value of line. It should be something like this.
import java.io.BufferedReader;
import java.io.FileReader;
public class InsertValuesIntoTestDb {
@SuppressWarnings("rawtypes")
public static void main(String[] args) throws Exception {
String splitBy = ",";
BufferedReader br = new BufferedReader(new FileReader("test.csv"));
while((line = br.readLine()) != null){
String[] b = line.split(splitBy);
System.out.println(b[0]);
}
br.close();
}
}
readLine returns each line and only returns null when there is nothing left. The above code sets line and then checks if it is null.
Better answer was here:
set "i=hello " world"
set i|find """" >nul && echo contains || echo not_contains
Some of you were complaining that radios and such are cleared of default "checked" status... All you have to do is add the :radio, :checkbox selectors to the .not and the problem is solved.
If you can't get all the other reset functions to work, this one will.
Adapted from ngen's answer
function form_reset(formID){
$(':input','#'+formID)
.not(':button',':submit',':reset',':hidden',':radio',':checkbox')
.val('');
}
I tried for almost 4 Hours with this and finally figuring it out with guidance from here, I thought I would share my solution with you.
Ok so my domain is an addon domain. I also got "ERROR for site owner: Invalid domain for site key" I had checked that everything was correct almost a thousand times and it looked right to me, until I thought of it in terms of a desktop shortcut.
Solution:
So for an addon domain make sure that the parent url is also in the list of domains i.e: [ADDON DOMAIN].[PARENT DOMAIN].com . The addon location will be the folder that you set on your host so when using addon domains ensure to name the root with something logical.
Hope this helps someone else and thanks for the suggestions people.
What about a basic
your_string.strip("0")
to remove both trailing and leading zeros ? If you're only interested in removing trailing zeros, use .rstrip
instead (and .lstrip
for only the leading ones).
More info in the doc.
You could use some list comprehension to get the sequences you want like so:
trailing_removed = [s.rstrip("0") for s in listOfNum]
leading_removed = [s.lstrip("0") for s in listOfNum]
both_removed = [s.strip("0") for s in listOfNum]
If you're doing this in Drupal and use the Form API to change the #type from text to 'hidden' in hook_form_alter (for example), be advised that the output HTML will have different (or omitted) DIV wrappers, IDs and class names.
If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params
with a MultivalueMap instead of adding each .param
:
LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");
mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())
Your should create ptr as follows:
char *ptr;
You have created ptr as an array of pointers to chars. The above creates a single pointer to a char.
Edit: complete code should be:
char *ptr;
char arr[5] = {'a','b','c','d','e'};
ptr = arr;
printf("\nvalue:%c", *(ptr+0));
I had a similar error while I was creating a custom modal.
const CustomModal = (visible, modalText, modalHeader) => {}
Problem was that I didn't wrap my values to curly brackets like this.
const CustomModal = ({visible, modalText, modalHeader}) => {}
If you have multiple values to pass to the component, you should use curly brackets around it.
Add your li
to a class, and do $(".myclass").hide();
at the start to hide it instead of the visibility style attribute.
As far as I know, jquery uses the display
style attribute to show/hide elements instead of visibility (may be wrong on that one, in either case the above is worth trying)

From MSDN: SqlCommand.ExecuteNonQuery Method
You can use the ExecuteNonQuery to perform catalog operations (for example, querying the structure of a database or creating database objects such as tables), or to change the data in a database without using a DataSet by executing UPDATE, INSERT, or DELETE statements.
Although the ExecuteNonQuery returns no rows, any output parameters or return values mapped to parameters are populated with data.
For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.
You are using SELECT query, thus you get -1
Another possible reason for this problem is that your OS runs python3 by default.
Either you have to explicitly do: python2 manage.py
or you need to edit the shebang of manage.py
, like so:
#!/usr/bin/env python2
or if you are using python3:
#!/usr/bin/env python3
//It is working
#include<iostream>
using namespace std;
void main()
{
int a[5];
int temp=0;
cout<<"Enter Values"<<endl;
for(int i=0;i<5;i++)
{
cin>>a[i];
}
for(int i=0;i<5;i++)
{
for(int j=0;j<5;j++)
{
if(a[i]>a[j])
{
temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
}
cout<<"Asending Series"<<endl;
for(int i=0;i<5;i++)
{
cout<<endl;
cout<<a[i]<<endl;
}

We do it here for the local variables if we think they will not be reassigned or should not be reassigned.
The parameters are not final since we have a Checkstyle-Check which checks for reassigning parameters. Of course nobody would ever want to reassign a parameter variable.
I used (LocalDB)\MSSQLLocalDB as the server name, I was then able to see all the local databases.
.toString()
is available, or just add ""
to the end of the int
var x = 3,
toString = x.toString(),
toConcat = x + "";

Best way to store date
in SQlite DB is to store the current DateTimeMilliseconds
. Below is the code snippet to do so_
- Get the
DateTimeMilliseconds
public static long getTimeMillis(String dateString, String dateFormat) throws ParseException {
/*Use date format as according to your need! Ex. - yyyy/MM/dd HH:mm:ss */
String myDate = dateString;//"2017/12/20 18:10:45";
SimpleDateFormat sdf = new SimpleDateFormat(dateFormat/*"yyyy/MM/dd HH:mm:ss"*/);
Date date = sdf.parse(myDate);
long millis = date.getTime();
return millis;
}
- Insert the data in your DB
public void insert(Context mContext, long dateTimeMillis, String msg) {
//Your DB Helper
MyDatabaseHelper dbHelper = new MyDatabaseHelper(mContext);
database = dbHelper.getWritableDatabase();
ContentValues contentValue = new ContentValues();
contentValue.put(MyDatabaseHelper.DATE_MILLIS, dateTimeMillis);
contentValue.put(MyDatabaseHelper.MESSAGE, msg);
//insert data in DB
database.insert("your_table_name", null, contentValue);
//Close the DB connection.
dbHelper.close();
}
Now, your data (date is in currentTimeMilliseconds) is get inserted in DB .
Next step is, when you want to retrieve data from DB you need to convert the respective date time milliseconds in to corresponding date. Below is the sample code snippet to do the same_
- Convert date milliseconds in to date string.
public static String getDate(long milliSeconds, String dateFormat)
{
// Create a DateFormatter object for displaying date in specified format.
SimpleDateFormat formatter = new SimpleDateFormat(dateFormat/*"yyyy/MM/dd HH:mm:ss"*/);
// Create a calendar object that will convert the date and time value in milliseconds to date.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(milliSeconds);
return formatter.format(calendar.getTime());
}
- Now, Finally fetch the data and see its working...
public ArrayList<String> fetchData() {
ArrayList<String> listOfAllDates = new ArrayList<String>();
String cDate = null;
MyDatabaseHelper dbHelper = new MyDatabaseHelper("your_app_context");
database = dbHelper.getWritableDatabase();
String[] columns = new String[] {MyDatabaseHelper.DATE_MILLIS, MyDatabaseHelper.MESSAGE};
Cursor cursor = database.query("your_table_name", columns, null, null, null, null, null);
if (cursor != null) {
if (cursor.moveToFirst()){
do{
//iterate the cursor to get data.
cDate = getDate(cursor.getLong(cursor.getColumnIndex(MyDatabaseHelper.DATE_MILLIS)), "yyyy/MM/dd HH:mm:ss");
listOfAllDates.add(cDate);
}while(cursor.moveToNext());
}
cursor.close();
//Close the DB connection.
dbHelper.close();
return listOfAllDates;
}
Hope this will help all! :)

Handling database versions is very important part of application development. I assume that you already have class AppDbHelper extending SQLiteOpenHelper
. When you extend it you will need to implement onCreate
and onUpgrade
method.
When onCreate
and onUpgrade
methods called
onCreate
called when app newly installed.onUpgrade
called when app updated. Organizing Database versions
I manage versions in a class methods. Create implementation of interface Migration. E.g. For first version create MigrationV1
class, second version create MigrationV1ToV2
(these are my naming convention)
public interface Migration {
void run(SQLiteDatabase db);//create tables, alter tables
}
Example migration:
public class MigrationV1ToV2 implements Migration{
public void run(SQLiteDatabase db){
//create new tables
//alter existing tables(add column, add/remove constraint)
//etc.
}
}
onCreate
: Since onCreate
will be called when application freshly installed, we also need to execute all migrations(database version updates). So onCreate
will looks like this:
public void onCreate(SQLiteDatabase db){
Migration mV1=new MigrationV1();
//put your first database schema in this class
mV1.run(db);
Migration mV1ToV2=new MigrationV1ToV2();
mV1ToV2.run(db);
//other migration if any
}
onUpgrade
: This method will be called when application is already installed and it is updated to new application version. If application contains any database changes then put all database changes in new Migration class and increment database version.
For example, lets say user has installed application which has database version 1, and now database version is updated to 2(all schema updates kept in MigrationV1ToV2
). Now when application upgraded, we need to upgrade database by applying database schema changes in MigrationV1ToV2
like this:
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (oldVersion < 2) {
//means old version is 1
Migration migration = new MigrationV1ToV2();
migration.run(db);
}
if (oldVersion < 3) {
//means old version is 2
}
}
Note: All upgrades (mentioned in
onUpgrade
) in to database schema should be executed inonCreate

what will solve with this?
Java 8 (
Stream.of
andStream.concat
)
The proposed solution is for three lists though it can be applied for two lists as well. In Java 8 we can make use of Stream.of or Stream.concat as:
List<String> result1 = Stream.concat(Stream.concat(list1.stream(),list2.stream()),list3.stream()).collect(Collectors.toList());
List<String> result2 = Stream.of(list1,list2,list3).flatMap(Collection::stream).collect(Collectors.toList());
Stream.concat
takes two streams as input and creates a lazily concatenated stream whose elements are all the elements of the first stream followed by all the elements of the second stream. As we have three lists we have used this method (Stream.concat
) two times.
We can also write a utility class with a method that takes any number of lists (using varargs) and returns a concatenated list as:
public static <T> List<T> concatenateLists(List<T>... collections) {
return Arrays.stream(collections).flatMap(Collection::stream).collect(Collectors.toList());
}
Then we can make use of this method as:
List<String> result3 = Utils.concatenateLists(list1,list2,list3);

it's because the name of the submit button is named "submit", change it to anything but "submit", try "submitme" and retry it. It should then work.
Look here http://docs.oracle.com/javase/6/docs/api/java/awt/Font.html#deriveFont%28float%29
JComponent has a setFont() method. You will control the font there, not on the String.
Such as
JButton b = new JButton();
b.setFont(b.getFont().deriveFont(18.0f));
The best way is,
var first = '2012-11-21';
var second = '2012-11-03';
if (new Date(first) > new Date(second) {
.....
}
I had this same issue and solved it by going to the file it was erroring on:

Note: Preparing XXXHDPI is not needed and also maybe XXHDPI size too because of the repeating areas of 9-patch images. On the other hand, if only Portrait sizes are used the App size could be more less. More pictures mean more space is need.
I think there is no an exact size for the all devices. I use Xperia Z 5". If you develop a crossplatform-webview app you should consider a lot of things (whether screen has softkey navigation buttons or not, etc). Therefore, I think there is only one suitable solution. The solution is to prepare a 9-patch splash screen (find How to design a new splash screen
heading below).
That's it!
Cordova specific code
To be added lines into the config.xml for 9-patch splash screens
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="6000" />
<platform name="android">
<splash src="res/screen/android/ldpi.9.png" density="ldpi"/>
<splash src="res/screen/android/mdpi.9.png" density="mdpi"/>
<splash src="res/screen/android/hdpi.9.png" density="hdpi"/>
<splash src="res/screen/android/xhdpi.9.png" density="xhdpi"/>
</platform>
To be added lines into the config.xml when using non-9-patch splash screens
<platform name="android">
<splash src="res/screen/android/splash-land-hdpi.png" density="land-hdpi"/>
<splash src="res/screen/android/splash-land-ldpi.png" density="land-ldpi"/>
<splash src="res/screen/android/splash-land-mdpi.png" density="land-mdpi"/>
<splash src="res/screen/android/splash-land-xhdpi.png" density="land-xhdpi"/>
<splash src="res/screen/android/splash-port-hdpi.png" density="port-hdpi"/>
<splash src="res/screen/android/splash-port-ldpi.png" density="port-ldpi"/>
<splash src="res/screen/android/splash-port-mdpi.png" density="port-mdpi"/>
<splash src="res/screen/android/splash-port-xhdpi.png" density="port-xhdpi"/>
</platform>
I would describe a simple way to create proper splash screen using this way. Assume we're designing a 1280dp x 720dp - xhdpi (x-large) screen. I've written for the sake of example the below;
In Photoshop: File -> New in new dialog window set your screens
Width: 720 Pixels Height: 1280 Pixels
I guess the above sizes mean Resolution is 320 Pixels/Inch. But to ensure you can change resolution value to 320 in your dialog window. In this case Pixels/Inch = DPI
Congratulations... You have a 720dp x 1280dp splash screen template.
After you designed your splash screen, if you want to design 9-Patch splash screen, you should insert 1 pixel gap for every side. For this reason you should increase +2 pixel your canvas size's width and height ( now your image sizes are 722 x 1282 ).
I've left the blank 1 pixel gap at every side as directed the below.
Changing the canvas size by using Photoshop:
- Open a splash screen png file in Photoshop
- Click onto the lock icon next to the 'Background' name in the Layers field (to leave blank instead of another color like white) if there is like the below:
- Change the canvas size from Image menu ( Width: 720 pixels to 722 pixels and Height: 1280 pixels to 1282 pixels). Now, should see 1 pixel gap at every side of the splash screen image.
Then you can use C:\Program Files (x86)\Android\android-studio\sdk\tools\draw9patch.bat to convert a 9-patch file. For that open your splash screen on draw9patch app. You should define your logo and expandable areas. Notice the black line the following example splash screen. The black line's thickness is just 1 px ;) Left and Top sides black lines define your splash screen's must display area. Exactly as your designed. Right and Bottom lines define the addable and removable area (automatically repeating areas).
Just do that: Zoom your image's top edge on draw9patch application. Click and drag your mouse to draw line. And press shift + click and drag your mouse to erase line.
If you develop a cross-platform app (like Cordova/PhoneGap) you can find the following address almost all mabile OS splash screen sizes. Click for Windows Phone, WebOS, BlackBerry, Bada-WAC and Bada splash screen sizes.

We can append or prepend two lists or list&array
Append:
var l = List(1,2,3)
l = l :+ 4
Result : 1 2 3 4
var ar = Array(4, 5, 6)
for(x <- ar)
{ l = l :+ x }
l.foreach(println)
Result:1 2 3 4 5 6
Prepending:
var l = List[Int]()
for(x <- ar)
{ l= x :: l } //prepending
l.foreach(println)
Result:6 5 4 1 2 3
If you don't want to assign identifier to the hidden field; you can use name or class with selector like:
$('input[name=hiddenfieldname]').val();
or with assigned class:
$('input.hiddenfieldclass').val();

This great option makes it easier to select the images in many cases.
Slideshow video with one image per second

ffmpeg -framerate 1 -pattern_type glob -i '*.png' -i audio.ogg \
-c:a copy -shortest -c:v libtheora -r 30 -pix_fmt yuv420p out.ogg
Your images should of course be sorted alphabetically, typically as:
0001-first-thing.jpg
0002-second-thing.jpg
0003-and-third.jpg
and so on.
I would also first ensure that all images to be used have the same aspect ratio, possibly by cropping them with imagemagick
or nomacs beforehand, so that ffmpeg will not have to make hard decisions. In particular, the width has to be divisible by 2, otherwise conversion fails with: "width not divisible by 2".

# Convert all to PNG for consistency.
# https://unix.stackexchange.com/questions/29869/converting-multiple-image-files-from-jpeg-to-pdf-format
# Hardlink the ones that are already PNG.
mkdir -p png
mogrify -format png -path png orig/*.jpg
ln -P orig/*.png png
Now we have a quick look at all image sizes to decide on the final aspect ratio:
identify png/*
which outputs:
png/1.png PNG 557x495 557x495+0+0 8-bit sRGB 653KB 0.000u 0:00.000
png/2.png PNG 664x800 664x800+0+0 8-bit sRGB 853KB 0.000u 0:00.000
png/3.png PNG 544x680 544x680+0+0 8-bit sRGB 442KB 0.000u 0:00.000
png/4.png PNG 207x238 207x238+0+0 8-bit sRGB 76.8KB 0.000u 0:00.000
png/5.png PNG 450x600 450x600+0+0 8-bit sRGB 627KB 0.000u 0:00.000
so the classic 480p (640x480 == 4/3) aspect ratio seems appropriate.
Do one conversion with minimal resizing to make widths even (TODO
automate for any width, here I just manually looked at identify
output and reduced width and height by one):
mkdir -p raw
convert png/1.png -resize 556x494 raw/1.png
ln -P png/2.png png/3.png png/4.png png/5.png raw
ffmpeg -framerate 1 -pattern_type glob -i 'raw/*.png' -i orig/audio.ogg -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p raw.mp4
This produces terrible output, because as seen from:
ffprobe raw.mp4
ffmpeg just takes the size of the first image, 556x494, and then converts all others to that exact size, breaking their aspect ratio.
Now let's convert the images to the target 480p aspect ratio automatically by cropping as per ImageMagick: how to minimally crop an image to a certain aspect ratio?
mkdir -p auto
mogrify -path auto -geometry 640x480^ -gravity center -crop 640x480+0+0 png/*.png
ffmpeg -framerate 1 -pattern_type glob -i 'auto/*.png' -i orig/audio.ogg -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p auto.mp4
So now, the aspect ratio is good, but inevitably some cropping had to be done, which kind of cut up interesting parts of the images.
The other option is to pad with black background to have the same aspect ratio as shown at: Resize to fit in a box and set background to black on "empty" part
mkdir -p black
ffmpeg -framerate 1 -pattern_type glob -i 'black/*.png' -i orig/audio.ogg -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p black.mp4
Generally speaking though, you will ideally be able to select images with the same or similar aspect ratios to avoid those problems in the first place.
About the CLI options
Note however that despite the name, -glob
this is not as general as shell Glob patters, e.g.: -i '*'
fails: https://trac.ffmpeg.org/ticket/3620 (apparently because filetype is deduced from extension).
-r 30
makes the -framerate 1
video 30 FPS to overcome bugs in players like VLC for low framerates: VLC freezes for low 1 FPS video created from images with ffmpeg Therefore it repeats each frame 30 times to keep the desired 1 image per second effect.

Bibliography
Integers (int
for short) are the numbers you count with 0, 1, 2, 3 ... and their negative counterparts ... -3, -2, -1 the ones without the decimal part.
So once you introduce a decimal point, your not really dealing with integers. You're dealing with rational numbers. The Python float or decimal types are what you want to represent or approximate these numbers.
You may be used to a language that automatically does this for you(Php). Python, though, has an explicit preference for forcing code to be explicit instead implicit.
I encountered the same bug and found the root reason is:
Use Application Context to inflate view.
Inflating with Activity Context fixed the bug.
When you do this,
while((inputLine = buff_read.readLine())!= null){
System.out.println(inputLine);
}
You consume everything in instream, so instream is empty. Now when try to do this,
Document doc = builder.parse(instream);
The parsing will fail, because you have passed it an empty stream.
Can't you just count the rows using select count(*) from table
(or an indexed column instead of * if speed is important)?
If not then maybe this article can point you in the right direction.

As for this date (February 2017), it seems that mailchimp has integrated something similar to what gbinflames suggests into their own javascript generated form.
You don't need any further intervention now as mailchimp will convert the form to an ajax submitted one when javascript is enabled.
All you need to do now is just paste the generated form from the embed menu into your html page and NOT modify or add any other code.
This simply works. Thanks MailChimp!

Just for an overview of Laravel Authentication
Laravel Authentication facilities comes with Guard and Providers, Guards define how users are authenticated for each request whereas Providers define how users are retrieved from you persistent storage.
Database Consideration - By default Laravel includes an App\User Eloquent Model in your app directory.
Auth Namespace - App\Http\Controllers\Auth
Controllers - RegisterController, LoginController, ForgotPasswordController and ResetPasswordController, all names are meaningful and easy to understand!
Routing - Laravel/ui package provides a quick way to scaffold all the routes and views you need for authentication using a few simple commands (as mentioned in the start instead of make:auth).
You can disable any newly created controller, e. g. RegisterController and modify your route declaration like, Auth::routes(['register' => false]); For further detail please look into the Laravel Documentation.

I want to give a shoutout for using re
module for this. Specially in the case of case sensitivity.
We use the option re.IGNORECASE while compiling the regex for use of in production environments with large amounts of data.
>>> import re
>>> m = ['isalnum','isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'ISALNUM', 'ISALPHA', 'ISDIGIT', 'ISLOWER', 'ISSPACE', 'ISTITLE', 'ISUPPER']
>>>
>>>
>>> pattern = re.compile('is')
>>>
>>> [word for word in m if pattern.match(word)]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']
However try to always use the in
operator for string comparison as detailed in this post

Here's an example that uses proper usings and implementation of idisposable:
static void WriteToFile(string sourceFile, string destinationfile, bool append = true, int bufferSize = 4096)
{
using (var sourceFileStream = new FileStream(sourceFile, FileMode.OpenOrCreate))
{
using (var destinationFileStream = new FileStream(destinationfile, FileMode.OpenOrCreate))
{
while (sourceFileStream.Position < sourceFileStream.Length)
{
destinationFileStream.WriteByte((byte)sourceFileStream.ReadByte());
}
}
}
}
...and there's also this
public static void WriteToFile(Stream stream, string destinationFile, int bufferSize = 4096, FileMode mode = FileMode.OpenOrCreate, FileAccess access = FileAccess.ReadWrite, FileShare share = FileShare.ReadWrite)
{
using (var destinationFileStream = new FileStream(destinationFile, mode, access, share))
{
while (stream.Position < stream.Length)
{
destinationFileStream.WriteByte((byte)stream.ReadByte());
}
}
}
The key is understanding the proper use of using (which should be implemented on the instantiation of the object that implements idisposable as shown above), and having a good idea as to how the properties work for streams. Position is literally the index within the stream (which starts at 0) that is followed as each byte is read using the readbyte method. In this case I am essentially using it in place of a for loop variable and simply letting it follow through all the way up to the length which is LITERALLY the end of the entire stream (in bytes). Ignore in bytes because it is practically the same and you will have something simple and elegant like this that resolves everything cleanly.
Keep in mind, too, that the ReadByte method simply casts the byte to an int in the process and can simply be converted back.
I'm gonna add another implementation I recently wrote to create a dynamic buffer of sorts to ensure sequential data writes to prevent massive overload
private void StreamBuffer(Stream stream, int buffer)
{
using (var memoryStream = new MemoryStream())
{
stream.CopyTo(memoryStream);
var memoryBuffer = memoryStream.GetBuffer();
for (int i = 0; i < memoryBuffer.Length;)
{
var networkBuffer = new byte[buffer];
for (int j = 0; j < networkBuffer.Length && i < memoryBuffer.Length; j++)
{
networkBuffer[j] = memoryBuffer[i];
i++;
}
//Assuming destination file
destinationFileStream.Write(networkBuffer, 0, networkBuffer.Length);
}
}
}
The explanation is fairly simple: we know that we need to keep in mind the entire set of data we wish to write and also that we only want to write certain amounts, so we want the first loop with the last parameter empty (same as while). Next, we initialize a byte array buffer that is set to the size of what's passed, and with the second loop we compare j to the size of the buffer and the size of the original one, and if it's greater than the size of the original byte array, end the run.

How do I rename a specific column in pandas?
From v0.24+, to rename one (or more) columns at a time,
DataFrame.rename()
with axis=1
or axis='columns'
(the axis
argument was introduced in v0.21
.
Index.str.replace()
for string/regex based replacement.
If you need to rename ALL columns at once,
DataFrame.set_axis()
method with axis=1
. Pass a list-like sequence. Options are available for in-place modification as well.rename
with axis=1
df = pd.DataFrame('x', columns=['y', 'gdp', 'cap'], index=range(5))
df
y gdp cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
With 0.21+, you can now specify an axis
parameter with rename
:
df.rename({'gdp':'log(gdp)'}, axis=1)
# df.rename({'gdp':'log(gdp)'}, axis='columns')
y log(gdp) cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
(Note that rename
is not in-place by default, so you will need to assign the result back.)
This addition has been made to improve consistency with the rest of the API. The new axis
argument is analogous to the columns
parameter—they do the same thing.
df.rename(columns={'gdp': 'log(gdp)'})
y log(gdp) cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
rename
also accepts a callback that is called once for each column.
df.rename(lambda x: x[0], axis=1)
# df.rename(lambda x: x[0], axis='columns')
y g c
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
For this specific scenario, you would want to use
df.rename(lambda x: 'log(gdp)' if x == 'gdp' else x, axis=1)
Index.str.replace
Similar to replace
method of strings in python, pandas Index and Series (object dtype only) define a ("vectorized") str.replace
method for string and regex-based replacement.
df.columns = df.columns.str.replace('gdp', 'log(gdp)')
df
y log(gdp) cap
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
The advantage of this over the other methods is that str.replace
supports regex (enabled by default). See the docs for more information.
set_axis
with axis=1
Call set_axis
with a list of header(s). The list must be equal in length to the columns/index size. set_axis
mutates the original DataFrame by default, but you can specify inplace=False
to return a modified copy.
df.set_axis(['cap', 'log(gdp)', 'y'], axis=1, inplace=False)
# df.set_axis(['cap', 'log(gdp)', 'y'], axis='columns', inplace=False)
cap log(gdp) y
0 x x x
1 x x x
2 x x x
3 x x x
4 x x x
Note: In future releases, inplace
will default to True
.
Method Chaining
Why choose set_axis
when we already have an efficient way of assigning columns with df.columns = ...
? As shown by Ted Petrou in this answer set_axis
is useful when trying to chain methods.
Compare
# new for pandas 0.21+
df.some_method1()
.some_method2()
.set_axis()
.some_method3()
Versus
# old way
df1 = df.some_method1()
.some_method2()
df1.columns = columns
df1.some_method3()
The former is more natural and free flowing syntax.
For my PHP/MySQL based calendar, I wanted to store repeating/recurring event information as efficiently as possibly. I didn't want to have a large number of rows, and I wanted to easily lookup all events that would take place on a specific date.
The method below is great at storing repeating information that occurs at regular intervals, such as every day, every n days, every week, every month every year, etc etc. This includes every Tuesday and Thursday type patterns as well, because they are stored separately as every week starting on a Tuesday and every week starting on a Thursday.
Assuming I have two tables, one called events
like this:
ID NAME
1 Sample Event
2 Another Event
And a table called events_meta
like this:
ID event_id meta_key meta_value
1 1 repeat_start 1299132000
2 1 repeat_interval_1 432000
With repeat_start being a date with no time as a unix timestamp, and repeat_interval an amount in seconds between intervals (432000 is 5 days).
repeat_interval_1 goes with repeat_start of the ID 1. So if I have an event that repeats every Tuesday and every Thursday, the repeat_interval would be 604800 (7 days), and there would be 2 repeat_starts and 2 repeat_intervals. The table would look like this:
ID event_id meta_key meta_value
1 1 repeat_start 1298959200 -- This is for the Tuesday repeat
2 1 repeat_interval_1 604800
3 1 repeat_start 1299132000 -- This is for the Thursday repeat
4 1 repeat_interval_3 604800
5 2 repeat_start 1299132000
6 2 repeat_interval_5 1 -- Using 1 as a value gives us an event that only happens once
Then, if you have a calendar that loops through every day, grabbing the events for the day it's at, the query would look like this:
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
RIGHT JOIN `events_meta` EM2 ON EM2.`meta_key` = CONCAT( 'repeat_interval_', EM1.`id` )
WHERE EM1.meta_key = 'repeat_start'
AND (
( CASE ( 1299132000 - EM1.`meta_value` )
WHEN 0
THEN 1
ELSE ( 1299132000 - EM1.`meta_value` )
END
) / EM2.`meta_value`
) = 1
LIMIT 0 , 30
Replacing {current_timestamp}
with the unix timestamp for the current date (Minus the time, so the hour, minute and second values would be set to 0).
Hopefully this will help somebody else too!
This method is better suited for storing complex patterns such as
Event A repeats every month on the 3rd of the month starting on March 3, 2011
or
Event A repeats Friday of the 2nd week of the month starting on March 11, 2011
I'd recommend combining this with the above system for the most flexibility. The tables for this should like like:
ID NAME
1 Sample Event
2 Another Event
And a table called events_meta
like this:
ID event_id meta_key meta_value
1 1 repeat_start 1299132000 -- March 3rd, 2011
2 1 repeat_year_1 *
3 1 repeat_month_1 *
4 1 repeat_week_im_1 2
5 1 repeat_weekday_1 6
repeat_week_im
represents the week of the current month, which could be between 1 and 5 potentially. repeat_weekday
in the day of the week, 1-7.
Now assuming you are looping through the days/weeks to create a month view in your calendar, you could compose a query like this:
SELECT EV . *
FROM `events` AS EV
JOIN `events_meta` EM1 ON EM1.event_id = EV.id
AND EM1.meta_key = 'repeat_start'

This combined with the above method could be combined to cover most repeating/recurring event patterns. If I've missed anything please leave a comment.
Just write what you really wanted to know:
fac.GetCachedValue("Auto Print Clinical Warnings").ToLower().StartsWith("y")
It's much simpler than anything with substring.
Those are users. Check your /etc/passwd
.
cd ~username
takes you to that user's home directory.
A POD (plain old data) object has one of these data types--a fundamental type, pointer, union, struct, array, or class--with no constructor. Conversely, a non-POD object is one for which a constructor exists. A POD object begins its lifetime when it obtains storage with the proper size for its type and its lifetime ends when the storage for the object is either reused or deallocated.
PlainOldData types also must not have any of:
A looser definition of PlainOldData includes objects with constructors; but excludes those with virtual anything. The important issue with PlainOldData types is that they are non-polymorphic. Inheritance can be done with POD types, however it should only be done for ImplementationInheritance (code reuse) and not polymorphism/subtyping.
A common (though not strictly correct) definition is that a PlainOldData type is anything that doesn't have a VeeTable.
This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.
Security considerations
The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.
find out what you have assigned to 'list' by displaying it
>>> print(list)
if it has content, you have to clean it with
>>> del list
now display 'list' again and expect this
<class 'list'>
Once you see this, you can proceed with your copy.

This was in response to your other question, that looks like it's been deleted....the point still stands.
Looks like a classic Unicode to ASCII issue. The trick would be to find where it's happening.
.NET works fine with Unicode, assuming it's told it's Unicode to begin with (or left at the default).
My guess is that your receiving app can't handle it. So, I'd probably use the ASCIIEncoder with an EncoderReplacementFallback with String.Empty:
using System.Text;
string inputString = GetInput();
var encoder = ASCIIEncoding.GetEncoder();
encoder.Fallback = new EncoderReplacementFallback(string.Empty);
byte[] bAsciiString = encoder.GetBytes(inputString);
// Do something with bytes...
// can write to a file as is
File.WriteAllBytes(FILE_NAME, bAsciiString);
// or turn back into a "clean" string
string cleanString = ASCIIEncoding.GetString(bAsciiString);
// since the offending bytes have been removed, can use default encoding as well
Assert.AreEqual(cleanString, Default.GetString(bAsciiString));
Of course, in the old days, we'd just loop though and remove any chars greater than 127...well, those of us in the US at least. ;)
You can try the c++ open source project WinRobot @git, a powerful screen capturer
CComPtr<IWinRobotService> pService;
hr = pService.CoCreateInstance(__uuidof(ServiceHost) );
//get active console session
CComPtr<IUnknown> pUnk;
hr = pService->GetActiveConsoleSession(&pUnk);
CComQIPtr<IWinRobotSession> pSession = pUnk;
// capture screen
pUnk = 0;
hr = pSession->CreateScreenCapture(0,0,1280,800,&pUnk);
// get screen image data(with file mapping)
CComQIPtr<IScreenBufferStream> pBuffer = pUnk;

Had the same issue, but my code must work on both PHP 5 & PHP 7..

Same answer as above, but with async await
and ready to use!
const fs = require('fs/promises');
const path = require('path');
async function isExists(path) {
try {
await fs.access(path);
return true;
} catch {
return false;
}
};
async function writeFile(filePath, data) {
try {
const dirname = path.dirname(filePath);
const exist = await isExists(dirname);
if (!exist) {
await fs.mkdir(dirname, {recursive: true});
}
await fs.writeFile(filePath, data, 'utf8');
} catch (err) {
throw new Error(err);
}
}
Example:
(async () {
const data = 'Hello, World!';
await writeFile('dist/posts/hello-world.html', data);
})();
The best that I've been able to do is
$(this).closest('.modal').modal('toggle');
This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.
You can however do this:
$(".modal:visible").modal('toggle');
This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

Interesting info about MSCorlib:
.NET 1.1
assembly will reference the 1.1 mscorlib
but will use
the 2.0 mscorlib at runtime (due to hard-coded version redirects in
theruntime itself)MSCorlib 2.0
alone is in GAC whereas 1.x version live inside framework folderI found that simply setting the line-height and height to the same pixel quantity produced the most consistent result. By "most consistent" I mean optimally consistent but of course it is not 100% "pixel-perfect" across browsers. Additionally I found that Firefox (v. 17.x) tends to crowd the option text to the right against the drop-down arrow; I alleviated this with a small amount of padding-right set on the OPTION element only. This setting does not affect appearance in IE 7-9.
My result:
select, option {
font-size:10px;
height:19px;
line-height: 19px;
padding:0;
margin:0;
}
option {
padding-right:6px; /* Firefox */
}
NOTE -- my SELECT element uses a smaller font, 10px. Obviously you will need to adjust proportions accordingly for your specific UI context.
I had a lot of trouble getting opencv 3.0 to work on OSX with python3 bindings and virtual environments. The other answers helped a lot, but it still took a bit. Hopefully this will help the next person. Save this to build_opencv.sh
. Then download opencv, modify the variables in the below shell script, cross your fingers, and run it (. ./build_opencv.sh
). For debugging, use the other posts, especially James Fletchers.
Don't forget to add the opencv lib dir to your PYTHONPATH.
Note - this also downloads opencv-contrib, where many of the functions have been moved. And they are also now referenced by a different namespace than the documentation - for instance SIFT is now under cv2.xfeatures2d.SIFT_create. Uggh.

I was using old version 1.0.beta.6
of handlebars, i think somewhere during 1.1 - 1.3 this functionality was added, so updating to 1.3.0 solved the issue, here is the usage:
Usage:
{{#each object}}
Key {{@key}} : Value {{this}}
{{/people}}
Another solution: go through a filter with your inverted conditions : Example :
if(subscribtion.isOnce() && subscribtion.isCalled()){
continue;
}
can be replaced with
.filter(s -> !(s.isOnce() && s.isCalled()))
The most straightforward approach seem to be using "return;" though.
You can use print_r
, var_dump
and var_export
funcations of php:
print_r
: Convert into human readble form
<?php
echo "<pre>";
print_r($results);
echo "</pre>";
?>
var_dump()
: will show you the type of the thing as well as what's in it.
var_dump($results);
foreach loop
: using for each loop you can iterate each and every value of an array.
foreach($results['data'] as $result) {
echo $result['type'].'<br>';
}
Sometimes using row.getLastCellNum()
gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.
private int getLastFilledCellPosition(Row row) {
int columnIndex = -1;
for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
Cell cell = row.getCell(i);
if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
continue;
} else {
columnIndex = cell.getColumnIndex();
break;
}
}
return columnIndex;
}

class Rectangle {
protected $x, $y;
public function __construct($x, $y) {
$this->x = $x;
$this->y = $y;
}
}
class Square extends Rectangle {
public function __construct($x) {
parent::__construct($x, $x);

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.
There is a performance comparison with YAJL and JsonCPP.
Update:
I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.
In short:
self
as it suggests, refers to itself- the object which has called the method. That is, if you have N objects calling the method, then self.a
will refer to a separate instance of the variable for each of the N objects. Imagine N copies of the variable a
for each object__init__
is what is called as a constructor in other OOP languages such as C++/Java. The basic idea is that it is a special method which is automatically called when an object of that Class is createdYou're over-complicating it - it just needs to be:
void generateArray(int *a, int si)
{
for (int j = 0; j < si; j++)
a[j] = rand() % 9;
}
int main()
{
const int size=5;
int a[size];
generateArray(a, size);
return 0;
}
When you pass an array as a parameter to a function it decays to a pointer to the first element of the array. So there is normally never a need to pass a pointer to an array.
That's no struts related problem but rather plain HMTL/CSS.
I'm not HTML or CSS expert, but I guess you could use a div with a border on the left or right side only.
For those using JaVers, given an audited entity class, you may want to ignore the properties causing the LazyInitializationException
exception (e.g. by using the @DiffIgnore
annotation).
This tells the framework to ignore those properties when calculating the object differences, so it won't try to read from the DB the related objects outside the transaction scope (thus causing the exception).
I would recommend Ulrich Drepper's SHA-256/SHA-512 based crypt implementation.
We ported these algorithms to Java, and you can find a freely licensed version of them at ftp://ftp.arlut.utexas.edu/java_hashes/.
Note that most modern (L)Unices support Drepper's algorithm in their /etc/shadow files.
You can use Javascript to get the viewport width and height. Then pass the values back via a hidden form input or ajax.
var width = $(window).width();
var height = $(window).height();
Assuming you have: JQuery framework.
First, add these hidden form inputs to store the width and height until postback.
<asp:HiddenField ID="width" runat="server" />
<asp:HiddenField ID="height" runat="server" />
Next we want to get the window (viewport) width and height. JQuery has two methods for this, aptly named width() and height().
Add the following code to your .aspx file within the head element.
<script type="text/javascript">
$(document).ready(function() {
$("#width").val() = $(window).width();
$("#height").val() = $(window).height();
});
</script>
Result
This will result in the width and height of the browser window being available on postback. Just access the hidden form inputs like this:
var TheBrowserWidth = width.Value;
var TheBrowserHeight = height.Value;
This method provides the height and width upon postback, but not on the intial page load.
Note on UpdatePanels: If you are posting back via UpdatePanels, I believe the hidden inputs need to be within the UpdatePanel.
Alternatively you can post back the values via an ajax call. This is useful if you want to react to window resizing.
Update for jquery 3.1.1
I had to change the JavaScript to:
$("#width").val($(window).width());
$("#height").val($(window).height());
Gone through the already posted answers. Just thought it would be better if I add an answer with actual example.
Let' say you have 3 Django models which are related.
class M1(models.Model):
name = models.CharField(max_length=10)
class M2(models.Model):
name = models.CharField(max_length=10)
select_relation = models.ForeignKey(M1, on_delete=models.CASCADE)
prefetch_relation = models.ManyToManyField(to='M3')
class M3(models.Model):
name = models.CharField(max_length=10)
Here you can query M2
model and its relative M1
objects using select_relation
field and M3
objects using prefetch_relation
field.
However as we've mentioned M1
's relation from M2
is a ForeignKey
, it just returns only 1 record for any M2
object. Same thing applies for OneToOneField
as well.
But M3
's relation from M2
is a ManyToManyField
which might return any number of M1
objects.
Consider a case where you have 2 M2
objects m21
, m22
who have same 5 associated M3
objects with IDs 1,2,3,4,5
. When you fetch associated M3
objects for each of those M2
objects, if you use select related, this is how it's going to work.
Steps:
m21
object.M3
objects related to m21
object whose IDs are 1,2,3,4,5
.m22
object and all other M2
objects.As we have same 1,2,3,4,5
IDs for both m21
, m22
objects, if we use select_related option, it's going to query the DB twice for the same IDs which were already fetched.
Instead if you use prefetch_related, when you try to get M2
objects, it will make a note of all the IDs that your objects returned (Note: only the IDs) while querying M2
table and as last step, Django is going to make a query to M3
table with the set of all IDs that your M2
objects have returned. and join them to M2
objects using Python instead of database.
This way you're querying all the M3
objects only once which improves performance.
You have 2 options
1) Use javascript to confirm deletion (use onsubmit event handler), however if the client has JS disabled, you're in trouble.
2) Use PHP to echo out a confirmation message, along with the contents of the form (hidden if you like) as well as a submit button called "confirmation", in PHP check if $_POST["confirmation"]
is set.
Use like blow
i use this command and solve
"Uncaught TypeError: Cannot read property 'msie' of undefined" Error

The differences are covered at the PostgreSQL documentation for date/time types. Yes, the treatment of TIME
or TIMESTAMP
differs between one WITH TIME ZONE
or WITHOUT TIME ZONE
. It doesn't affect how the values are stored; it affects how they are interpreted.
The effects of time zones on these data types is covered specifically in the docs. The difference arises from what the system can reasonably know about the value:
With a time zone as part of the value, the value can be rendered as a local time in the client.
Without a time zone as part of the value, the obvious default time zone is UTC, so it is rendered for that time zone.
The behaviour differs depending on at least three factors:
WITH TIME ZONE
or WITHOUT TIME ZONE
) of the value.Here are examples covering the combinations of those factors:
foo=> SET TIMEZONE TO 'Japan';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
timestamp
---------------------
2011-01-01 00:00:00
(1 row)
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
timestamptz
------------------------
2011-01-01 00:00:00+09
(1 row)
foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP;
timestamp
---------------------
2011-01-01 00:00:00
(1 row)
foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP WITH TIME ZONE;
timestamptz
------------------------
2011-01-01 06:00:00+09
(1 row)
foo=> SET TIMEZONE TO 'Australia/Melbourne';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
timestamp
---------------------
2011-01-01 00:00:00
(1 row)
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
timestamptz
------------------------
2011-01-01 00:00:00+11
(1 row)
foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP;
timestamp
---------------------
2011-01-01 00:00:00
(1 row)
foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP WITH TIME ZONE;

if anyone want to add a value inside loop then you can use this its working 100%
{% set ftotal= {'total': 0} %}
{%- for pe in payment_entry -%}
{% if ftotal.update({'total': ftotal.total + 5}) %}{% endif %}
{%- endfor -%}
{{ftotal.total}}
output = 5
I wanted something a bit slimmer for RSpec/Ruby so that the custom code only had to live in one place. Here's my solution:
/spec/support/selenium.rb
...
RSpec.configure do |config|
config.after(:suite) do
$custom_headers = nil
end
end
module RequestWithExtraHeaders
def headers
$custom_headers.each do |key, value|
self.set_header "HTTP_#{key}", value
end if $custom_headers
super
end
end
class ActionDispatch::Request
prepend RequestWithExtraHeaders
end
Then in my specs:
/specs/features/something_spec.rb
...
$custom_headers = {"Referer" => referer_string}
var fileName = 'file.txt';
// Getting Extension
var ext = fileName.split('.')[1];
// OR
var ext = fileName.split('.').pop();
Use xpath selector (here's quick tutorial) instead of id:
#python:
from selenium.webdriver import Firefox
YOUR_PAGE_URL = 'http://mypage.com/'
NEXT_BUTTON_XPATH = '//input[@type="submit" and @title="next"]'
browser = Firefox()
browser.get(YOUR_PAGE_URL)
button = browser.find_element_by_xpath(NEXT_BUTTON_XPATH)
button.click()
Or, if you use "vanilla" Selenium, just use same xpath selector instead of button id:
NEXT_BUTTON_XPATH = '//input[@type="submit" and @title="next"]'
selenium.click(NEXT_BUTTON_XPATH)
Fancybox currently does not directly support a way to automatically launch. The work around I was able to get working is creating a hidden anchor tag and triggering it's click event. Make sure your call to trigger the click event is included after the jQuery and Fancybox JS files are included. The code I used is as follows:
This sample script is embedded directly in the HTML, but it could also be included in a JS file.
<script type="text/javascript">
$(document).ready(function() {
$("#hidden_link").fancybox().trigger('click');
});
</script>
you can insert using loop if you want to insert some random values.
BEGIN
FOR x IN 1 .. 1000 LOOP
INSERT INTO MULTI_INSERT_DEMO (ID, NAME)
SELECT x, 'anyName' FROM dual;
END LOOP;
END;
Try to add a s
after http
Like this:
http://integration.jsite.com/data/vis

It works for me
Use UNSIGNED
for non-negative integers.
I think the best way to find out how your restore or backup progress is by the following query:
USE[master]
GO
SELECT session_id AS SPID, command, a.text AS Query, start_time, percent_complete, dateadd(second,estimated_completion_time/1000, getdate()) as estimated_completion_time
FROM sys.dm_exec_requests r CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) a
WHERE r.command in ('BACKUP DATABASE','RESTORE DATABASE')
GO
The query above, identify the session by itself and perform a percentage progress every time you press F5 or Execute button on SSMS!
The query was performed by the guy who write this post
You can return FileResult with this methods:
1: Return FileStreamResult
[HttpGet("get-file-stream/{id}"]
public async Task<FileStreamResult> DownloadAsync(string id)
{
var fileName="myfileName.txt";
var mimeType="application/....";
var stream = await GetFileStreamById(id);
return new FileStreamResult(stream, mimeType)
{
FileDownloadName = fileName
};
}
2: Return FileContentResult
[HttpGet("get-file-content/{id}"]
public async Task<FileContentResult> DownloadAsync(string id)
{
var fileName="myfileName.txt";
var mimeType="application/....";
var fileBytes = await GetFileBytesById(id);
return new FileContentResult(fileBytes, mimeType)
{
FileDownloadName = fileName
};
}

I believe that you can also do this:
git checkout alpha-0.3.0
git reset --hard cc4b63bebb6
git push origin +alpha-0.3.0
This is very similar to the last method, except you don't have to muck around in the remote repo.
Just wanted to add a comment in BRPocock, but I don't have the sufficient privilegies.
So my contribution was for everyone trying to install IBM Integration Toolkit from IBM's Integration Bus bundle.
When you try to run "Installation Manager" command from folder /Integration_Toolkit/IM_Linux (the file to run is "install") you get the error showed in this post.
Further instructions to fix this problem you'll find in this IBM's web page: https://www-304.ibm.com/support/docview.wss?uid=swg21459143
Hope this helps for anybody trying to install that.
I'm adding this answer because it solved a related problem that I was having with the same error message.
Problem: I had installed cygwin under Windows and was getting this error: Pseudo-terminal will not be allocated because stdin is not a terminal
Resolution: It turns out that I had not installed the openssh client program and utilities. Because of that cygwin was using the Windows implementation of ssh, not the cygwin version. The solution was to install the openssh cygwin package.
It seeems like you want to remove ONLY columns with ALL NA
s, leaving columns with some rows that do have NA
s. I would do this (but I am sure there is an efficient vectorised soution:
#set seed for reproducibility
set.seed <- 103
df <- data.frame( id = 1:10 , nas = rep( NA , 10 ) , vals = sample( c( 1:3 , NA ) , 10 , repl = TRUE ) )
df
# id nas vals
# 1 1 NA NA
# 2 2 NA 2
# 3 3 NA 1
# 4 4 NA 2
# 5 5 NA 2
# 6 6 NA 3
# 7 7 NA 2
# 8 8 NA 3
# 9 9 NA 3
# 10 10 NA 2
#Use this command to remove columns that are entirely NA values, it will elave columns where only some vlaues are NA
df[ , ! apply( df , 2 , function(x) all(is.na(x)) ) ]
# id vals
# 1 1 NA
# 2 2 2
# 3 3 1
# 4 4 2
# 5 5 2
# 6 6 3
# 7 7 2
# 8 8 3
# 9 9 3
# 10 10 2
If you find yourself in the situation where you want to remove columns that have any NA
values you can simply change the all
command above to any
.
If you are looking for a month picker try this jquery.mtz.monthpicker

Short circuiting means the second operator will not be checked if the first operator decides the final outcome.
E.g. Expression is: True || False
In case of ||, all we need is one of the side to be True. So if the left hand side is true, there is no point in checking the right hand side, and hence that will not be checked at all.
Similarly, False && True
In case of &&, we need both sides to be True. So if the left hand side is False, there is no point in checking the right hand side, the answer has to be False. And hence that will not be checked at all.

The simple way to use XMLHttpRequest
with pure JavaScript
. You can set custom header
but it's optional used based on requirement.
window.onload = function(){
var request = new XMLHttpRequest();
var params = "UID=CORS&name=CORS";
request.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(this.responseText);
}
};
request.open('POST', 'https://www.example.com/api/createUser', true);
request.setRequestHeader('api-key', 'your-api-key');
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
request.send(params);
}
You can send params using POST method.
Please run below example and will get an JSON response.
window.onload = function(){_x000D_
var request = new XMLHttpRequest();_x000D_
_x000D_
request.onreadystatechange = function() {_x000D_
if (this.readyState == 4 && this.status == 200) {_x000D_
console.log(this.responseText);_x000D_
}_x000D_
};_x000D_
_x000D_
request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
request.send();_x000D_
}

This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.
set.py:
import sys
sys.path.append("/tmp/TEST")
loop.py
import sys
import time
while True:
print sys.path
time.sleep(1)
run: python loop.py &
This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py
. Each has a different set of environment variables. Observe that the output from loop.py
does not change because set.py
does not change loop.py
's environment.
A note on importing
Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append...
.
For the people which are looking for the opposite (aka fullscreen), it's very simple. Because you just have to replace the settings /min
by /max
.
Now the program will be open at the "maximized" size !
In the case, perhaps you will need an example : start /max explorer.exe
.
openssl pkcs12 -info -in keystore_file
Here is the code to create a simple one second timer tick:
using System;
using System.Threading;
class TimerExample
{
static public void Tick(Object stateInfo)
{
Console.WriteLine("Tick: {0}", DateTime.Now.ToString("h:mm:ss"));
}
static void Main()
{
TimerCallback callback = new TimerCallback(Tick);
Console.WriteLine("Creating timer: {0}\n",
DateTime.Now.ToString("h:mm:ss"));
// create a one second timer tick
Timer stateTimer = new Timer(callback, null, 0, 1000);
// loop here forever
for (; ; )
{
// add a sleep for 100 mSec to reduce CPU usage
Thread.Sleep(100);
}
}
}
And here is the resulting output:
c:\temp>timer.exe
Creating timer: 5:22:40
Tick: 5:22:40
Tick: 5:22:41
Tick: 5:22:42
Tick: 5:22:43
Tick: 5:22:44
Tick: 5:22:45
Tick: 5:22:46
Tick: 5:22:47
EDIT: It is never a good idea to add hard spin loops into code as they consume CPU cycles for no gain. In this case that loop was added just to stop the application from closing, allowing the actions of the thread to be observed. But for the sake of correctness and to reduce the CPU usage a simple Sleep call was added to that loop.
The biggest PITA of Oracle is that is does not have a default date format!
In your installation of Oracle the combination of Locales and install options has picked (the very sensible!) YYYY-MM-DD as the format for outputting dates. Another installation could have picked "DD/MM/YYYY" or "YYYY/DD/MM".
If you want your SQL to be portable to another Oracle site I would recommend you always wrap a TO_CHAR(datecol,'YYYY-MM-DD')
or similar function around each date column your SQL or alternativly set the defualt format immediatly after you connect with
ALTER SESSION
SET NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';
or similar.
If you want to create a typed list with values, here's the syntax.
Assuming a class of Student like
public class Student {
public int StudentID { get; set; }
public string StudentName { get; set; }
}
You can make a list like this:
IList<Student> studentList = new List<Student>() {
new Student(){ StudentID=1, StudentName="Bill"},
new Student(){ StudentID=2, StudentName="Steve"},
new Student(){ StudentID=3, StudentName="Ram"},
new Student(){ StudentID=1, StudentName="Moin"}

When I saw this question I thought of when I had to generate UUIDs. I can't take credit for the code, as I am sure I found it here on stackoverflow. If you dont want the dashes in your string then take out the dashes. Here is the function:
function generateUUID() {
var d = new Date().getTime();
var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g,function(c) {
var r = (d + Math.random()*16)%16 | 0;
d = Math.floor(d/16);
return (c=='x' ? r : (r&0x7|0x8)).toString(16);
});
return uuid.toUpperCase();
}
I was facing the same issue. I renamed my php folder from php7_winxxxx
to just php and it worked fine. It looked like composer was checking the location to the php_openssl module in c:/php/ext
.
You may also need to add c:/php
to the PATH
in environment variable
There is no longer a need for creating your own FAB nor using a third party library, it was included in AppCompat 22.
https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.html
Just add the new support library called design in in your gradle-file:
compile 'com.android.support:design:22.2.0'
...and you are good to go:
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_margin="16dp"
android:clickable="true"
android:src="@drawable/ic_happy_image" />
Lazy fetching decides whether to load child objects while loading the Parent Object.
You need to do this setting respective hibernate mapping file of the parent class.
Lazy = true
(means not to load child)
By default the lazy loading of the child objects is true.
This make sure that the child objects are not loaded unless they are explicitly invoked in the application by calling getChild()
method on parent.In this case hibernate issues a fresh database call to load the child when getChild()
is actully called on the Parent object.
But in some cases you do need to load the child objects when parent is loaded. Just make the lazy=false and hibernate will load the child when parent is loaded from the database.
Example : If you have a TABLE ? EMPLOYEE mapped to Employee object and contains set of Address objects. Parent Class : Employee class, Child class : Address Class
public class Employee {
private Set address = new HashSet(); // contains set of child Address objects
public Set getAddress () {
return address;
}
public void setAddresss(Set address) {
this. address = address;
}
}
In the Employee.hbm.xml file
<set name="address" inverse="true" cascade="delete" lazy="false">
<key column="a_id" />
<one-to-many class="beans Address"/>
</set>
In the above configuration.
If lazy="false"
: - when you load the Employee object that time child object Address is also loaded and set to setAddresss() method.
If you call employee.getAdress() then loaded data returns.No fresh database call.
If lazy="true"
:- This the default configuration. If you don?t mention then hibernate consider lazy=true.
when you load the Employee object that time child object Adress is not loaded. You need extra call to data base to get address objects.
If you call employee.getAdress()
then that time database query fires and return results. Fresh database call.
I had the same problem and found a very elegant solution for a Pager Class from
http://blogs.taiga.nl/martijn/2008/08/27/paging-with-aspnet-mvc/
In your controller the call looks like:
return View(partnerList.ToPagedList(currentPageIndex, pageSize));
and in your view:
<div class="pager">
Seite: <%= Html.Pager(ViewData.Model.PageSize,
ViewData.Model.PageNumber,
ViewData.Model.TotalItemCount)%>
</div>
Import-Csv $path | Foreach-Object {
foreach ($property in $_.PSObject.Properties)
{
doSomething $property.Name, $property.Value
}
}
If the columns that you are having trouble with are "hashes", then consider the following...
If the "hash" is a binary string, you should really use BINARY(...)
datatype.
If the "hash" is a hex string, you do not need utf8, and should avoid such because of character checks, etc. For example, MySQL's MD5(...)
yields a fixed-length 32-byte hex string. SHA1(...)
gives a 40-byte hex string. This could be stored into CHAR(32) CHARACTER SET ascii
(or 40 for sha1).
Or, better yet, store UNHEX(MD5(...))
into BINARY(16)
. This cuts in half the size of the column. (It does, however, make it rather unprintable.) SELECT HEX(hash) ...
if you want it readable.
Comparing two BINARY
columns has no collation issues.
I know this thread is a little old but it came in handy for a specific scenario I had and I thought it worth while to note that there is another reason why System.Threading.Timer
might be a good approach.
When you have to periodically execute a Job that might take a long time and you want to ensure that the entire waiting period is used between jobs or if you don't want the job to run again before the previous job has finished in the case where the job takes longer than the timer period.
You could use the following:
using System;
using System.ServiceProcess;
using System.Threading;
public partial class TimerExampleService : ServiceBase
{
private AutoResetEvent AutoEventInstance { get; set; }
private StatusChecker StatusCheckerInstance { get; set; }
private Timer StateTimer { get; set; }
public int TimerInterval { get; set; }
public CaseIndexingService()
{
InitializeComponent();
TimerInterval = 300000;
}
protected override void OnStart(string[] args)
{
AutoEventInstance = new AutoResetEvent(false);
StatusCheckerInstance = new StatusChecker();
// Create the delegate that invokes methods for the timer.
TimerCallback timerDelegate =
new TimerCallback(StatusCheckerInstance.CheckStatus);
// Create a timer that signals the delegate to invoke
// 1.CheckStatus immediately,
// 2.Wait until the job is finished,
// 3.then wait 5 minutes before executing again.
// 4.Repeat from point 2.
Console.WriteLine("{0} Creating timer.\n",
DateTime.Now.ToString("h:mm:ss.fff"));
//Start Immediately but don't run again.
StateTimer = new Timer(timerDelegate, AutoEventInstance, 0, Timeout.Infinite);
while (StateTimer != null)
{
//Wait until the job is done
AutoEventInstance.WaitOne();
//Wait for 5 minutes before starting the job again.
StateTimer.Change(TimerInterval, Timeout.Infinite);
}
//If the Job somehow takes longer than 5 minutes to complete then it wont matter because we will always wait another 5 minutes before running again.
}
protected override void OnStop()
{
StateTimer.Dispose();
}
}
class StatusChecker
{
public StatusChecker()
{
}
// This method is called by the timer delegate.
public void CheckStatus(Object stateInfo)
{
AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
Console.WriteLine("{0} Start Checking status.",
DateTime.Now.ToString("h:mm:ss.fff"));
//This job takes time to run. For example purposes, I put a delay in here.
int milliseconds = 5000;
Thread.Sleep(milliseconds);
//Job is now done running and the timer can now be reset to wait for the next interval
Console.WriteLine("{0} Done Checking status.",
DateTime.Now.ToString("h:mm:ss.fff"));
autoEvent.Set();
}
}
In Advance Tab -> scroll down and un-checked all options in advance security setting and try by checking one-by-one and finally app start running with one option TLS 1.1
that was the solution I got it.
First:
I think you can do it 2 ways
http://our.api.com/Product/<id>
: if you just want one record
http://our.api.com/Product
: if you want all records
http://our.api.com/Product/<id1>,<id2>
:as James suggested can be an option since what comes after the Product tag is a parameter
Or the one I like most is:
You can use the the Hypermedia as the engine of application state (HATEOAS) property of a RestFul WS and do a call http://our.api.com/Product
that should return the equivalent urls of http://our.api.com/Product/<id>
and call them after this.
Second
When you have to do queries on the url calls. I would suggest using HATEOAS again.
1) Do a get call to http://our.api.com/term/pumas/productType/clothing/color/black
2) Do a get call to http://our.api.com/term/pumas/productType/clothing,bags/color/black,red
3) (Using HATEOAS) Do a get call to `http://our.api.com/term/pumas/productType/ -> receive the urls all clothing possible urls -> call the ones you want (clothing and bags) -> receive the possible color urls -> call the ones you want

It's called Hiding Fields
From the link above
Within a class, a field that has the same name as a field in the superclass hides the superclass's field, even if their types are different. Within the subclass, the field in the superclass cannot be referenced by its simple name. Instead, the field must be accessed through super, which is covered in the next section. Generally speaking, we don't recommend hiding fields as it makes code difficult to read.
This works for me to reduce select tag's width;
<select id ="Select1" class="input-small">
You can use any one of these classes;
class="input-small"
class="input-medium"
class="input-large"
class="input-xlarge"
class="input-xxlarge"
Basically, you want to loop through each direct descendent of the old-parent node, and move it to the new parent. Any children of a direct descendent will get moved with it.
var newParent = document.getElementById('new-parent');
var oldParent = document.getElementById('old-parent');
while (oldParent.childNodes.length > 0) {
newParent.appendChild(oldParent.childNodes[0]);
}
There has been some debate around this point of contention, but even in the most recent documents android suggests that it's not such a good idea to use enums in an android application. The reason why is because they use up more memory than a static constants variable. Here is a document from a page of 2014 that advises against the use of enums in an android application. http://developer.android.com/training/articles/memory.html#Overhead
I quote:
Be aware of memory overhead
Be knowledgeable about the cost and overhead of the language and libraries you are using, and keep this information in mind when you design your app, from start to finish. Often, things on the surface that look innocuous may in fact have a large amount of overhead. Examples include:
Enums often require more than twice as much memory as static constants. You should strictly avoid using enums on Android.
Every class in Java (including anonymous inner classes) uses about 500 bytes of code.
Every class instance has 12-16 bytes of RAM overhead.
Putting a single entry into a HashMap requires the allocation of an additional entry object that takes 32 bytes (see the previous section about optimized data containers).
A few bytes here and there quickly add up—app designs that are class- or object-heavy will suffer from this overhead. That can leave you in the difficult position of looking at a heap analysis and realizing your problem is a lot of small objects using up your RAM.
There has been some places where they say that these tips are outdated and no longer valuable, but the reason they keep repeating it, must be there is some truth to it. Writing an android application is something you should keep as lightweight as possible for a smooth user experience. And every little inch of performance counts!
Such is how I have it embedded and outputted to my HTML web page:
<div class="container">
<p class="text-center">Copyright ©
<script>
var CurrentYear = new Date().getFullYear()
document.write(CurrentYear)
</script>
</p>
</div>
Output to HTML page is as follows:

If your DB is password protected, then the solution would be:
PGPASSWORD=password psql -U username -d dbname -c "select * from my_table"
While not yet supported on iOS (as of iOS 10), websites can send push notifications to Firefox and Chrome (Desktop/Android) with the Push API.
The Push API is used in conjunction with the older Web Notifications to display the message. The advantage is that the Push API allow the notification to be delivered even when the user is not surfing your website, because they are built upon Service Workers (scripts that are registered by the browser and can be executed in background at a later time even after your user has left your website).
The process of sending a notification involves the following:
The Push API is currently supported on desktop and Android by Chrome, Firefox and Opera.
You can also send push notifications to Apple / Safari desktop using APNs. The approach is similar, but with many complications (apple developer certificates, push packages, low-level TCP connection to APNs).
If you want to implement the push notifications by yourself start with these tutorials:
If you are looking for a drop in solution I would suggest Pushpad, which is a service I have built.
Update (September 2017): Apple has started developing the service workers for WebKit (status). Since the service workers are a fundamental technology for web push, this is a big step forward.
Only checked
and checked="checked"
are valid. Your other options depend on error recovery in browsers.
checked="yes"
and checked="true"
are particularly bad as they imply that checked="no"
and checked="false"
will set the default state to be unchecked … which they will not.
Use the FOR command to echo a file line by line, and with the 'skip' option to miss a number of starting lines...
FOR /F "skip=1" %i in (file2.txt) do @echo %i
You could redirect the output of a batch file, containing something like...
FOR /F %%i in (file1.txt) do @echo %%i
FOR /F "skip=1" %%i in (file2.txt) do @echo %%i
Note the double % when a FOR variable is used within a batch file.
The one I like is: cd C:
To have linux like feel then do:
ln -s /cygdrive/c/folder ~/folder
and use this like: ~/folder/..
