The following two are probably a good starting point. lodash also has a customizer function for those special needs!

keyCode is different for numbers on numeric keypad and numbers on top of keyboard.
keyCodes :
numbers on top of keyboard ( 0 - 9 ) : 48 - 57
numbers on numeric keypad ( 0 - 9 ) : 96 - 105
JavaScript condition :
if((e.keyCode >= 48 && e.keyCode <=57) || (e.keyCode >= 96 && e.keyCode <=105)) {
// entered key is a number
}

This link provides a lot of resources for VB6 Decompiling, but it seems like it will depend greatly on what you DO have (do you still have the pre-link Object code [EDIT: er... p-code I mean], or just the EXE?) Either way, it looks like there's something, take a look in there.
There are no such the way to detect browser close so probably you can't delete localStorage on browser close but there are another way to handle the things you can uses sessionCookies as it will destroy after browser close.This is I implemented in my project.
With Eclipse Collections you could create a primitive double list, sort it and then reverse it to put it in descending order. This approach would avoid boxing the doubles.
MutableDoubleList doubleList =
DoubleLists.mutable.with(
0.5, 0.2, 0.9, 0.1, 0.1, 0.1, 0.54, 0.71,
0.71, 0.71, 0.92, 0.12, 0.65, 0.34, 0.62)
.sortThis().reverseThis();
doubleList.each(System.out::println);
If you want a List<Double>
, then the following would work.
List<Double> objectList =
Lists.mutable.with(
0.5, 0.2, 0.9, 0.1, 0.1, 0.1, 0.54, 0.71,
0.71, 0.71, 0.92, 0.12, 0.65, 0.34, 0.62)
.sortThis(Collections.reverseOrder());
objectList.forEach(System.out::println);
If you want to keep the type as ArrayList<Double>
, you can initialize and sort the list using the ArrayListIterate
utility class as follows:
ArrayList<Double> arrayList =
ArrayListIterate.sortThis(
new ArrayList<>(objectList), Collections.reverseOrder());
arrayList.forEach(System.out::println);

The normal apporoach works the other way around: You create your build based upon maven or ant and then use integrations for your IDE of choice so that you are independent from it, which is esp. important when you try to bring new team members up to speed or use a contious integration server for automated builds. I recommend to use maven and let it do the heavy lifting for you. Create a pom file and generate the eclipse project via mvn eclipse:eclipse. HTH
While it looks like your setup is correct, there are a few things to check:
env
- specifically PATH
.command -v java
tells you what?java
executable in $JAVA_HOME\bin
and does it have the execute bit set? If not chmod a+x java
it.I trust you have source
'd your .profile
after adding/changing the JAVA_HOME
and PATH
?
Also, you can help yourself in future maintenance of your JDK installation by writing this instead:
export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35
export PATH=$JAVA_HOME/bin:$PATH
Then you only need to update one env variable when you setup the JDK installation.
Finally, you may need to run hash -r
to clear the Bash program cache. Other shells may need a similar command.

Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.
I reccomend you to use the following tools for online base64 encoding/decoding:
Check the "Format as Data URL" option to format as a Data URL.
I did it by the following way. number and name are two arraylist. I have to sort name .If any change happen to name arralist order then the number arraylist also change its order.
public void sortval(){
String tempname="",tempnum="";
if (name.size()>1) // check if the number of orders is larger than 1
{
for (int x=0; x<name.size(); x++) // bubble sort outer loop
{
for (int i=0; i < name.size()-x-1; i++) {
if (name.get(i).compareTo(name.get(i+1)) > 0)
{
tempname = name.get(i);
tempnum=number.get(i);
name.set(i,name.get(i+1) );
name.set(i+1, tempname);
number.set(i,number.get(i+1) );
number.set(i+1, tempnum);
}
}
}
}
}
Use $dec = $null
From the documentation:
$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.
PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.

Great question, great answers. Here's a quick way to echo the results if anyone is reading this page and missing that part:
$counter = mysql_query("SELECT COUNT(*) AS id FROM table");
$num = mysql_fetch_array($counter);
$count = $num["id"];
echo("$count");
Based on @pilau s answer - but with an improvement that even the accepted answer does not have.
<div class="angular-with-newlines" ng-repeat="item in items">
{{item.description}}
</div>
/* in the css file or in a style block */
.angular-with-newlines {
white-space: pre-line;
}
This will use newlines and whitespace as given, but also break content at the content boundaries. More information about the white-space property can be found here:
https://developer.mozilla.org/en-US/docs/Web/CSS/white-space
If you want to break on newlines, but also not collapse multiple spaces or white space preceeding the text (to render code or something), you can use:
white-space: pre-wrap;
Nice comparison of the different rendering modes: http://meyerweb.com/eric/css/tests/white-space.html
For those who are still running into this issue, the best way to make sure you don't get this error with a Map in a Tab is to make the Fragment extend SupportMapFragment
instead of nesting a SupportMapFragment
inside the Fragment used for the Tab.
I just got this working using a ViewPager
with a FragmentPagerAdapter
, with the SupportMapFragment in the third Tab.
Here is the general structure, note there is no need to override the onCreateView()
method, and there is no need to inflate any layout xml:
public class MapTabFragment extends SupportMapFragment
implements OnMapReadyCallback {
private GoogleMap mMap;
private Marker marker;
public MapTabFragment() {
}
@Override
public void onResume() {
super.onResume();
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
if (mMap == null) {
getMapAsync(this);
}
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
setUpMap();
}
private void setUpMap() {
mMap.setMyLocationEnabled(true);
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
mMap.getUiSettings().setMapToolbarEnabled(false);
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
@Override
public void onMapClick(LatLng point) {
//remove previously placed Marker
if (marker != null) {
marker.remove();
}
//place marker where user just clicked
marker = mMap.addMarker(new MarkerOptions().position(point).title("Marker")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)));
}
});
}
}
Result:
Here is the full class code that I used to test with, which includes the placeholder Fragment used for the first two Tabs, and the Map Fragment used for the third Tab:
public class MainActivity extends AppCompatActivity implements ActionBar.TabListener{

Here's the complete solution if you want to implement the wifi hotspot feature programmatically in your android app.
SOLUTION FOR API < 26:
For devices < API 26. There is no public API by Android for this purpose. So, in order to work with those APIs you've to access private APIs through reflection. It is not recommended but if you've no other options left, then here's a trick.
First of all, you need to have this permission in your manifest,
<uses-permission
android:name="android.permission.WRITE_SETTINGS"
tools:ignore="ProtectedPermissions"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
Here's how you can ask it on run-time:
private boolean showWritePermissionSettings() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
&& Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
if (!Settings.System.canWrite(this)) {
Log.v("DANG", " " + !Settings.System.canWrite(this));
Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS);
intent.setData(Uri.parse("package:" + this.getPackageName()));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);
return false;
}
}
return true; //Permission already given
}
You can then access the setWifiEnabled
method through reflection. This returns true if the action you asked for is being process correctly i.e. enabling/disabling hotspot.
public boolean setWifiEnabled(WifiConfiguration wifiConfig, boolean enabled) {
WifiManager wifiManager;
try {
if (enabled) { //disables wifi hotspot if it's already enabled
wifiManager.setWifiEnabled(false);
}
Method method = wifiManager.getClass()
.getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
return (Boolean) method.invoke(wifiManager, wifiConfig, enabled);
} catch (Exception e) {
Log.e(this.getClass().toString(), "", e);
return false;
}
}
You can also get the wificonfiguration of your hotspot through reflection. I've answered that method for this question on StackOverflow.
P.S: If you don't want to turn on hotspot programmatically, you can start this intent and open the wifi settings screen for user to turn it on manually.
SOLUTION FOR API >= 26:
Finally, android released an official API for versions >= Oreo. You can just use the public exposed API by android i.e. startLocalOnlyHotspot
It turns on a local hotspot without internet access. Which thus can be used to host a server or transfer files.
It requires Manifest.permission.CHANGE_WIFI_STATE
and ACCESS_FINE_LOCATION
permissions.
Here's a simple example of how you can turn on hotspot using this API.
private WifiManager wifiManager;
WifiConfiguration currentConfig;
WifiManager.LocalOnlyHotspotReservation hotspotReservation;
The method to turn on hotspot:
@RequiresApi(api = Build.VERSION_CODES.O)
public void turnOnHotspot() {
wifiManager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback() {
@Override
public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) {
super.onStarted(reservation);
hotspotReservation = reservation;
currentConfig = hotspotReservation.getWifiConfiguration();
Log.v("DANG", "THE PASSWORD IS: "
+ currentConfig.preSharedKey
+ " \n SSID is : "
+ currentConfig.SSID);
hotspotDetailsDialog();
}
@Override
public void onStopped() {
super.onStopped();
Log.v("DANG", "Local Hotspot Stopped");
}
@Override
public void onFailed(int reason) {
super.onFailed(reason);
Log.v("DANG", "Local Hotspot failed to start");
}
}, new Handler());
}
`
Here's how you can get details of the locally created hotspot
private void hotspotDetaisDialog()
{
Log.v(TAG, context.getString(R.string.hotspot_details_message) + "\n" + context.getString(
R.string.hotspot_ssid_label) + " " + currentConfig.SSID + "\n" + context.getString(
R.string.hotspot_pass_label) + " " + currentConfig.preSharedKey);
}
If it throws, a security exception even after giving the required permissions then you should try enabling your location using GPS. Here's the solution.
Recently, I've developed a demo app called Spotserve. That turns on wifi hotspot for all devices with API>=15 and hosts a demo server on that hotspot. You can check that for more details. Hope this helps!
There is a constant that you can check against:
someBigDecimal.compareTo(BigDecimal.ZERO) == 0
As documentation says:
Raised when the part of a "multipart/form-data" request identified by its name cannot be found.
This may be because the request is not a multipart/form-data either because the part is not present in the request, or because the web application is not configured correctly for processing multipart requests -- e.g. no MultipartResolver.
Workstation has some features that Player lacks, such as teams (groups of VMs connected by private LAN segments) and multi-level snapshot trees. It's aimed at power users and developers; they even have some hooks for using a debugger on the host to debug code in the VM (including kernel-level stuff). The core technology is the same, though.
You basically need to set top
and left
to 50%
to center the left-top corner of the div. You also need to set the margin-top
and margin-left
to the negative half of the div's height and width to shift the center towards the middle of the div.
Thus, provided a <!DOCTYPE html>
(standards mode), this should do:
position: fixed;
width: 500px;
height: 200px;
top: 50%;
left: 50%;
margin-top: -100px; /* Negative half of height. */
margin-left: -250px; /* Negative half of width. */
Or, if you don't care about centering vertically and old browsers such as IE6/7, then you can instead also add left: 0
and right: 0
to the element having a margin-left
and margin-right
of auto
, so that the fixed positioned element having a fixed width knows where its left and right offsets start. In your case thus:
position: fixed;
width: 500px;
height: 200px;
margin: 5% auto; /* Will not center vertically and won't work in IE6/7. */
left: 0;
right: 0;
Again, this works only in IE8+ if you care about IE, and this centers only horizontally not vertically.
You may also want to use hasOwnProperty in the loop.
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
switch (prop) {
// obj[prop] has the value
}
}
}
node.js is single-threaded which means your script will block whether you want it or not. Remember that V8 (Google's Javascript engine that node.js uses) compiles Javascript into machine code which means that most basic operations are really fast and looping through an object with 100 keys would probably take a couple of nanoseconds?
However, if you do a lot more inside the loop and you don't want it to block right now, you could do something like this
switch (prop) {
case 'Timestamp':
setTimeout(function() { ... }, 5);
break;
case 'Start_Value':
setTimeout(function() { ... }, 10);
break;
}
If your loop is doing some very CPU intensive work, you will need to spawn a child process to do that work or use web workers.
Here's a link to my tutorial, which walks you through :

You can use the path
module to join the path of the directory in which helper1.js
lives to the relative path of foobar.json
. This will give you the absolute path to foobar.json
.
var fs = require('fs');
var path = require('path');
var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');
This should work on Linux, OSX, and Windows assuming a UTF8 encoding.
The .NET component Excel Reader .NET may satisfy your requirement. It's good enought for reading XLSX and XLS files. So try it from:
var cars = [
manufacturer: [
{
color: 'gray',
model: '1',
nOfDoors: 4
},
{
color: 'yellow',
model: '2',
nOfDoors: 4
}
]
]
I use this solution:
It's a bit more concise since I use: ng-repeat="obj in objects | filter : paginate"
to filter the rows. Also made it working with $resource:
To view the stdout, you can start the docker container with -i
. This of course does not enable you to leave the started process and explore the container.
docker start -i containerid
Alternatively you can view the filesystem of the container at
/var/lib/docker/containers/containerid/root/
However neither of these are ideal. If you want to view logs or any persistent storage, the correct way to do so would be attaching a volume with the -v
switch when you use docker run
. This would mean you can inspect log files either on the host or attach them to another container and inspect them there.
brew install zlib
on OS X doesn't work anymore and instead prompts to install lzlib
. Installing that doesn't help.
Instead you install XCode Command line tools and that should install zlib
xcode-select --install
Your updateVelocity()
method is missing the explicit self
parameter in its definition.
Should be something like this:
def updateVelocity(self):
for x in range(0,len(self.velocity)):
self.velocity[x] = 2*random.random()*(self.pbestx[x]-self.current[x]) + 2 \
* random.random()*(self.gbest[x]-self.current[x])
Your other methods (except for __init__
) have the same problem.
You should check this: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/upgrade-insecure-requests
Add this meta tag to your index.html inside head
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
Hope it helped.
Here is the solution I was looking for. If you would like to create List2 that contains the difference of the number elements in List1.
list1 = [12, 15, 22, 54, 21, 68, 9, 73, 81, 34, 45]
list2 = []
for i in range(1, len(list1)):
change = list1[i] - list1[i-1]
list2.append(change)
Note that while len(list1)
is 11 (elements), len(list2)
will only be 10 elements because we are starting our for loop from element with index 1 in list1 not from element with index 0 in list1
This happened to me on a partition of type xfs (rw,relatime,seclabel,attr2,inode64,noquota)
, where the directories where owned by another user in a group we were both members of. The group membership was already established before login, and the whole directory structure was group-writeable. I had manually run sudo chown -R otheruser.group directory
and sudo chmod -R g+rw directory
to confirm this.
I still have no idea why it didn't work originally, but taking ownership with sudo chown -R myuser.group directory
fixed it. Perhaps SELinux-related?
Here is a solution using the javax.crypto library and the apache commons codec library for encoding and decoding in Base64:
import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;
public class TrippleDes {
private static final String UNICODE_FORMAT = "UTF8";
public static final String DESEDE_ENCRYPTION_SCHEME = "DESede";
private KeySpec ks;
private SecretKeyFactory skf;
private Cipher cipher;
byte[] arrayBytes;
private String myEncryptionKey;
private String myEncryptionScheme;
SecretKey key;
public TrippleDes() throws Exception {
myEncryptionKey = "ThisIsSpartaThisIsSparta";
myEncryptionScheme = DESEDE_ENCRYPTION_SCHEME;
arrayBytes = myEncryptionKey.getBytes(UNICODE_FORMAT);
ks = new DESedeKeySpec(arrayBytes);
skf = SecretKeyFactory.getInstance(myEncryptionScheme);
cipher = Cipher.getInstance(myEncryptionScheme);
key = skf.generateSecret(ks);
}
public String encrypt(String unencryptedString) {
String encryptedString = null;
try {
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] plainText = unencryptedString.getBytes(UNICODE_FORMAT);
byte[] encryptedText = cipher.doFinal(plainText);
encryptedString = new String(Base64.encodeBase64(encryptedText));
} catch (Exception e) {
e.printStackTrace();
}
return encryptedString;
}
public String decrypt(String encryptedString) {
String decryptedText=null;
try {
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] encryptedText = Base64.decodeBase64(encryptedString);
byte[] plainText = cipher.doFinal(encryptedText);
decryptedText= new String(plainText);
} catch (Exception e) {
e.printStackTrace();
}
return decryptedText;
}
public static void main(String args []) throws Exception
{
TrippleDes td= new TrippleDes();
String target="imparator";
String encrypted=td.encrypt(target);
String decrypted=td.decrypt(encrypted);
System.out.println("String To Encrypt: "+ target);
System.out.println("Encrypted String:" + encrypted);
System.out.println("Decrypted String:" + decrypted);
}
}
Running the above program results with the following output:
String To Encrypt: imparator
Encrypted String:FdBNaYWfjpWN9eYghMpbRA==
Decrypted String:imparator

You might look at how pygame handles this to steal some ideas.
Tab is [HT], or character number 9, in the unicode library.
For C++ you can use: http://www.pinvoke.net/default.aspx/gdi32/BitBlt.html
This may hower not work on all types of 3D applications/video apps. Then this link may be more useful as it describes 3 different methods you can use.
Old answer (C#):
You can use System.Drawing.Graphics.Copy, but it is not very fast.
A sample project I wrote doing exactly this: http://blog.tedd.no/index.php/2010/08/16/c-image-analysis-auto-gaming-with-source/
I'm planning to update this sample using a faster method like Direct3D: http://spazzarama.com/2009/02/07/screencapture-with-direct3d/
And here is a link for capturing to video: How to capture screen to be video using C# .Net?
Short answer: Put the executable file in /usr/local/bin
instead of applications. You should now be able to run commands like ngrok http 80
.
Long answer: When you type commands like ngrok
in the terminal, Macs (and other Unix OSs) look for these programs in the folders specified in your PATH
. The PATH
is a list of folders that's specified by each user. To check your path, open the terminal and type: echo $PATH
.
You'll see output that looks something like: /usr/local/bin:/usr/bin:/bin
. This is a :
separated list of folders.
So when you type ngrok
in the terminal, your Mac will look for this executable in the following folders: /usr/local/bin
, /usr/bin/
and /bin
.
Read this post if you are interested in learning about why you should prefer usr/local/bin
over other folders.
There is no specific option to disable caching only for JavaScript, you will have to disable caching entirely.
FireBug has an option to disable the browser cache on the Network tab's drop down menu.
if put 'http_errors' => false
in guzzle request options, then it would stop throw exception while get 4xx or 5xx error, like this: $client->get(url, ['http_errors' => false])
. then you parse the response, not matter it's ok or error, it would be in the response

int* test();
but it would be "more C++" to use vectors:
std::vector< int > test();
EDIT
I'll clarify some point. Since you mentioned C++, I'll go with new[]
and delete[]
operators, but it's the same with malloc/free.
In the first case, you'll write something like:
int* test() {
return new int[size_needed];
}
but it's not a nice idea because your function's client doesn't really know the size of the array you are returning, although the client can safely deallocate it with a call to delete[]
.
int* theArray = test();
for (size_t i; i < ???; ++i) { // I don't know what is the array size!
// ...
}
delete[] theArray; // ok.
A better signature would be this one:
int* test(size_t& arraySize) {
array_size = 10;
return new int[array_size];
}
And your client code would now be:
size_t theSize = 0;
int* theArray = test(theSize);
for (size_t i; i < theSize; ++i) { // now I can safely iterate the array
// ...
}
delete[] theArray; // still ok.
Since this is C++, std::vector<T>
is a widely-used solution:
std::vector<int> test() {
std::vector<int> vector(10);
return vector;
}
Now you don't have to call delete[]
, since it will be handled by the object, and you can safely iterate it with:
std::vector<int> v = test();
std::vector<int>::iterator it = v.begin();
for (; it != v.end(); ++it) {
// do your things
}
which is easier and safer.
This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n
and the output of np.add.reduce()
are both scalars, this implies that the problem lies with xm
and ym
, the two of which are simply your x
and y
inputs minus their respective means.
Based on this, my guess is that your x
and y
inputs have different shapes from one another, making them incompatible for element-wise multiplication.
** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.
Use pd.concat
to merge a list of DataFrame into a single big DataFrame.
appended_data = []
for infile in glob.glob("*.xlsx"):
data = pandas.read_excel(infile)
# store DataFrame in list
appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet
appended_data.to_excel('appended.xlsx')
In your project settings.py file,set ALLOWED_HOSTS like this :
ALLOWED_HOSTS = ['62.63.141.41', 'namjoosadr.com']
and then restart your apache. in ubuntu:
/etc/init.d/apache2 restart
Andrey's answer (the highest voted at the time of writing) is slightly incorrect. I would have added this as comment but I am not reputable enough.
In Andrey's answer:
char[] chars = {'c', 'h', 'a', 'r', 's'}
byte[] bytes = Charset.forName("UTF-8").encode(CharBuffer.wrap(chars)).array();
the call to array() may not return the desired value, for example:
char[] c = "aaaaaaaaaa".toCharArray();
System.out.println(Arrays.toString(Charset.forName("UTF-8").encode(CharBuffer.wrap(c)).array()));
output:
[97, 97, 97, 97, 97, 97, 97, 97, 97, 97, 0]
As can be seen a zero byte has been added. To avoid this use the following:
char[] c = "aaaaaaaaaa".toCharArray();
ByteBuffer bb = Charset.forName("UTF-8").encode(CharBuffer.wrap(c));
byte[] b = new byte[bb.remaining()];
bb.get(b);
System.out.println(Arrays.toString(b));
output:
[97, 97, 97, 97, 97, 97, 97, 97, 97, 97]
As the answer also alluded to using passwords it might be worth blanking out the array that backs the ByteBuffer (accessed via the array() function):
ByteBuffer bb = Charset.forName("UTF-8").encode(CharBuffer.wrap(c));
byte[] b = new byte[bb.remaining()];
bb.get(b);
blankOutByteArray(bb.array());
System.out.println(Arrays.toString(b));
For completeness and correct resource management:
ICursor cursor = null;
try
{
cursor = db.RawQuery("SELECT * FROM " + RECORDS_TABLE + " WHERE " + RECORD_ID + "=?", new String[] { id + "" });
if (cursor.Count > 0)
{
cursor.MoveToFirst();
}
return GetRecordFromCursor(cursor); // Copy cursor props to custom obj
}
finally // IMPORTANT !!! Ensure cursor is not left hanging around ...
{
if(cursor != null)
cursor.Close();
}
curl -X PUT -d 'new_value' URL_PATH/key

Will your development be linear? If so, you should stick with Subversion.
If on the other hand, your development will not be linear, which means that you will need to create branching for different changes, and then merging such changes back to the main development line (known to Git as the master branch) then Git will do MUCH more for you.
The setw manipulator function will be of help here.

For Amazon s3 you need to edit your CORS configuration:
<CORSConfiguration>
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<MaxAgeSeconds>3000</MaxAgeSeconds>
<AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
</CORSConfiguration>
Use the @import
method:
@import url('https://fonts.googleapis.com/css?family=Open+Sans&display=swap');
Obviously, "Open Sans" (Open+Sans
) is the font that is imported. So replace it with yours. If the font's name has multiple words, URL-encode it by adding a +
sign between each word, as I did.
Make sure to place the @import
at the very top of your CSS, before any rules.
Google Fonts can automatically generate the @import
directive for you. Once you have chosen a font, click the (+)
icon next to it. In bottom-left corner, a container titled "1 Family Selected" will appear. Click it, and it will expand. Use the "Customize" tab to select options, and then switch back to "Embed" and click "@import" under "Embed Font". Copy the CSS between the <style>
tags into your stylesheet.
You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.
It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1
E.g.:
GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer mF_9.B5f-4.1JqM
Where mF_9.B5f-4.1JqM is your OAuth access token.
Just to add to other answers, if you're using Django, it is advisable that you install mysql-python BEFORE installing Django.
With Scanner the default delimiters are the whitespace characters.
But Scanner can define where a token starts and ends based on a set of delimiter, wich could be specified in two ways:
So useDelimiter()
methods are used to tokenize the Scanner input, and behave like StringTokenizer class, take a look at these tutorials for further information:
And here is an Example:
public static void main(String[] args) {
// Initialize Scanner object
Scanner scan = new Scanner("Anna Mills/Female/18");
// initialize the string delimiter
scan.useDelimiter("/");
// Printing the tokenized Strings
while(scan.hasNext()){
System.out.println(scan.next());
}
// closing the scanner stream
scan.close();
}
Prints this output:
Anna Mills
Female
18
Very important point here to understand , the SurfaceView size must be the same as the camera parameters size , it means they have the same aspect ratio then the Stretch effect will go off .
You have to get the correct supported camera preview size using params.getSupportedPreviewSizes() choose one of them and then change your SurfaceView and its holders to this size.
You can use request.getQueryString()
,if the query string is like
username=james&password=pwd
To get name you can do this
request.getParameter("username");
I've found that the ''.join(chr(ord(a)^ord(b)) for a,b in zip(s,m)) method is pretty slow. Instead, I've been doing this:

m = struct.unpack(fmt, xor_data)
final = struct.pack(fmt, *(a ^ b for a, b in izip(s, m)))
word of warning: the prefs:root
or App-Prefs:root
URL schemes are considered private API. Apple may reject you app if you use those, here is what you may get when submitting your app:
Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change. Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.
Next Steps
To resolve this issue, please revise your app to provide the associated functionality using public APIs or remove the functionality using the "prefs:root" or "App-Prefs:root" URL scheme.
If there are no alternatives for providing the functionality your app requires, you can file an enhancement request.
I experienced this error when trying to embed an iframe and then opening the site with Brave. The error went away when I changed to "Shields Down" for the site in question. Obviously, this is not a full solution, since anyone else visiting the site with Brave will run into the same issue. To actually resolve it I would need to do one of the other things listed on this page. But at least I now know where the problem lies.
Unfortunately, most of the articles on state machines are written for C++ or other languages that have direct support for polymorphism as it's nice to model the states in an FSM implementation as classes that derive from an abstract state class.
However, it's pretty easy to implement state machines in C using either switch statements to dispatch events to states (for simple FSMs, they pretty much code right up) or using tables to map events to state transitions.
There are a couple of simple, but decent articles on a basic framework for state machines in C here:
Edit: Site "under maintenance", web archive links:
switch
statement-based state machines often use a set of macros to 'hide' the mechanics of the switch
statement (or use a set of if
/then
/else
statements instead of a switch
) and make what amounts to a "FSM language" for describing the state machine in C source. I personally prefer the table-based approach, but these certainly have merit, are widely used, and can be effective especially for simpler FSMs.
One such framework is outlined by Steve Rabin in "Game Programming Gems" Chapter 3.0 (Designing a General Robust AI Engine).
A similar set of macros is discussed here:
If you're also interested in C++ state machine implementations there's a lot more that can be found. I'll post pointers if you're interested.
Does it matter which is faster, if they don't do the same thing? Comparing the performance of statements with different meaning seems like a bad idea.
is

Not the same thing.
Since one div is initially hidden, you can simply call toggle for both divs:
<a href="javascript:void(0);" id="forgot-password">forgot password?</a>
<div id="login-form">login form</div>
<div id="recover-password" style="display:none;">recover password</div>
<script type="text/javascript">
$(function(){
$('#forgot-password').click(function(){
$('#login-form').toggle();
$('#recover-password').toggle();
});
});

ggplot 3.3.0
fixes this by providing guide_axis(angle = 90)
(as guide
argument to scale_..
or as x
argument to guides
):
library(ggplot2)
data(diamonds)
diamonds$cut <- paste("Super Dee-Duper", as.character(diamonds$cut))
ggplot(diamonds, aes(cut, carat)) +
geom_boxplot() +
scale_x_discrete(guide = guide_axis(angle = 90)) +
# ... or, equivalently:
# guides(x = guide_axis(angle = 90)) +
NULL
From the documentation of the angle
argument:
Compared to setting the angle in theme() / element_text(), this also uses some heuristics to automatically pick the hjust and vjust that you probably want.
Alternatively, it also provides guide_axis(n.dodge = 2)
(as guide
argument to scale_..
or as x
argument to guides
) to overcome the over-plotting problem by dodging the labels vertically. It works quite well in this case:
library(ggplot2)
data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))
ggplot(diamonds, aes(cut, carat)) +
geom_boxplot() +
scale_x_discrete(guide = guide_axis(n.dodge = 2)) +

Here's a solution using a negative lookahead (not supported in all regex engines):

Test that it works as expected:
import re
tests = [
('a', True),
('_', False),
('zz', True),
('a0', True),
('A_', False),
('a0_b', True),
('a__b', False),
('a_1_c', True),
]
regex = '^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$'
for test in tests:
is_match = re.match(regex, test[0]) is not None
if is_match != test[1]:
print "fail: " + test[0]
A .zip
file is required in order to include npm modules in Lambda. And you really shouldn't be using the Lambda web editor for much of anything- as with any production code, you should be developing locally, committing to git, etc.
1) My Lambda functions are usually helper utilities for a larger project, so I create a /aws/lambdas directory within that to house them.
2) Each individual lambda directory contains an index.js file containing the function code, a package.json file defining dependencies, and a /node_modules subdirectory. (The package.json file is not used by Lambda, it's just so we can locally run the npm install
command.)
package.json:
{
"name": "my_lambda",
"dependencies": {
"svg2png": "^4.1.1"
}
}
3) I .gitignore all node_modules directories and .zip files so that the files generated from npm installs and zipping won't clutter our repo.
.gitignore:
# Ignore node_modules
**/node_modules
# Ignore any zip files
*.zip
4) I run npm install
from within the directory to install modules, and develop/test the function locally.
5) I .zip the lambda directory and upload it via the console.
(IMPORTANT: Do not use Mac's 'compress' utility from Finder to zip the file! You must run zip from the CLI from within the root of the directory- see here)
zip -r ../yourfilename.zip *
NOTE:
You might run into problems if you install the node modules locally on your Mac, as some platform-specific modules may fail when deployed to Lambda's Linux-based environment. (See https://stackoverflow.com/a/29994851/165673)
The solution is to compile the modules on an EC2 instance launched from the AMI that corresponds with the Lambda Node.js runtime you're using (See this list of Lambda runtimes and their respective AMIs).

I'm finding that Tomcat can't seem to find classes defined in other projects, maybe even in the main project. It's failing on the filter definition which is the first definition in web.xml. If I add the project and its dependencies to the server's launch configuration then I just move on to a new error, all of which seems to point to it not setting up the project properly.
Our setup is quite complex. We have multiple components as projects in Eclipse with separate output projects. We have a separate webapp directory which contains the static HTML and images, as well as our WEB-INF.
Eclipse is "Europa Winter release". Tomcat is 6.0.18. I tried version 2.4 and 2.5 of the "Dynamic Web Module" facet.

Set the anchor property of the control to hook to all sides of the parent - top, bottom, left, and right.
To show leading zeros infront of hours, minutes and seconds use below modified code. The trick here is we are converting (or more accurately formatting) integer into string so that it shows leading zero whenever applicable :
public String convertTimeWithTimeZome(long time) {
Calendar cal = Calendar.getInstance();
cal.setTimeZone(TimeZone.getTimeZone("UTC"));
cal.setTimeInMillis(time);
String curTime = String.format("%02d:%02d:%02d", cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE), cal.get(Calendar.SECOND));
return curTime;
}
Result would be like : 00:01:30
I also faced the same issue at the first time.
Now it is fixed:
First, you copy the /etc/mysql/mysql.conf.d/mysqld.cnf
file and past in to /etc/mysql/my.cnf
.
You can do it by command:
sudo cp /etc/mysql/mysql.conf.d/mysqld.cnf /etc/mysql/my.cnf
Now let's Rest the password:
Use the following commands in your terminal:
sudo service mysql stop
sudo service mysql start
sudo mysql -u root
Now you are inside the mysql console.
Then let's write some queries to reset our root password
USE mysql
update mysql.user set authentication_string=password('newpass') where user='root' and Host ='localhost';
update user set plugin="mysql_native_password";
flush privileges;
quit
Now we can clean /etc/mysql/my.cng
Open the above file in your editor and remove the whole lines inside the file.
After that let's restart mysql:
sudo mysql service restart
Now let's use mysql with newly created password:
sudo mysql -u root -p
Finally enter your newly created password.
Probably something like this? (UNTESTED)

It is easier to check if a rectangle is completly outside the other, so if it is either
on the left...
(r1.x + r1.width < r2.x)
or on the right...
(r1.x > r2.x + r2.width)
or on top...
(r1.y + r1.height < r2.y)
or on the bottom...
(r1.y > r2.y + r2.height)
of the second rectangle, it cannot possibly collide with it. So to have a function that returns a Boolean saying weather the rectangles collide, we simply combine the conditions by logical ORs and negate the result:
function checkOverlap(r1, r2) : Boolean
{
return !(r1.x + r1.width < r2.x || r1.y + r1.height < r2.y || r1.x > r2.x + r2.width || r1.y > r2.y + r2.height);
}
To already receive a positive result when touching only, we can change the "<" and ">" by "<=" and ">=".
For functions that do not have more than 2 parameters, you can pass them without defining your own interface. For example,
class Klass {
static List<String> foo(Integer a, String b) { ... }
}
class MyClass{
static List<String> method(BiFunction<Integer, String, List<String>> fn){
return fn.apply(5, "FooBar");
}
}
List<String> lStr = MyClass.method((a, b) -> Klass.foo((Integer) a, (String) b));
In BiFunction<Integer, String, List<String>>
, Integer
and String
are its parameters, and List<String>
is its return type.
For a function with only one parameter, you can use Function<T, R>
, where T
is its parameter type, and R
is its return value type. Refer to this page for all the interfaces that are already made available by Java.

If you want to use pure Ruby (no Rails), don't want to create extension methods (maybe you need this only in one or two places and don't want to pollute namespace with tons of methods) and don't want to edit hash in place (i.e., you're fan of functional programming like me), you can 'select':
>> x = {:a => 1, :b => 2, :c => 3}
=> {:a=>1, :b=>2, :c=>3}
>> x.select{|x| x != :a}
=> {:b=>2, :c=>3}
>> x.select{|x| ![:a, :b].include?(x)}
=> {:c=>3}
>> x
=> {:a=>1, :b=>2, :c=>3}
in Laravel 4 you can actually use an Event Listener for database queries.
Event::listen('illuminate.query', function($sql, $bindings)
{
foreach ($bindings as $val) {
$sql = preg_replace('/\?/', "'{$val}'", $sql, 1);
}
Log::info($sql);
});
Place this snippet anywhere, e.g. in start/global.php
. It'll write the queries to the info log (storage/log/laravel.log
).
If you use git LFS, git count-objects does not count your binaries, but only the pointers to them.
If your LFS files are managed by Artifactorys, you should use the REST API:
You just need to use the callbacks, from the documentation: https://github.com/fronteed/iCheck#callbacks
$('input').on('ifChecked', function(event){
alert(event.type + ' callback');
});
There are several ways to accomplish that in Vim. I don't know which are most similar to Sublime Text's though.
The first one would be via multiline insert mode. Put your cursor to the
second "a" in the first line, press Ctrl-V
, select all lines, then press I
, and
put in a doublequote. Pressing <esc>
will repeat the operation on every line.
The second one is via macros. Put the cursor on the first character, and start
recording a macro with qa
.
Go the your right with llll
, enter insert mode with
a
, put down a doublequote, exit insert mode, and go back to the beginning of
your row with <home>
(or equivalent). Press j
to move down one row.
Stop recording with q
.
And then replay the macro with @a
. Several times.
Does any of the above approaches work for you?
Jalf already linked to it, but the GOTW puts it quite nicely why exception specifications are not as useful as one might hope:
int Gunc() throw(); // will throw nothing (?)
int Hunc() throw(A,B); // can only throw A or B (?)
Are the comments correct? Not quite.
Gunc()
may indeed throw something, andHunc()
may well throw something other than A or B! The compiler just guarantees to beat them senseless if they do… oh, and to beat your program senseless too, most of the time.
That's just what it comes down to, you probably just will end up with a call to terminate()
and your program dying a quick but painful death.
The GOTWs conclusion is:
So here’s what seems to be the best advice we as a community have learned as of today:
- Moral #1: Never write an exception specification.
- Moral #2: Except possibly an empty one, but if I were you I’d avoid even that.
See following snippet :
$(document).on("click", "a.deleteText", function() {_x000D_
if (confirm('Are you sure ?')) {_x000D_
$(this).prev('span.text').remove();_x000D_
}_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div class="container">_x000D_
<span class="text">some text</span>_x000D_
<a href="#" class="deleteText"><span class="delete-icon"> x Delete </span></a>_x000D_
</div>

In SUSE Linux Enterprise Server (SLES) and openSUSE the global one is located at /etc/vimrc
.
To edit it, simply do vi /etc/vimrc

I had the same problem but the issue was a different one, I was trying to create a service and pass $scope to it as a parameter.
That's another way to get this error as the documentation of that link says:
Attempting to inject a scope object into anything that's not a controller or a directive, for example a service, will also throw an Unknown provider: $scopeProvider <- $scope error. This might happen if one mistakenly registers a controller as a service, ex.:
angular.module('myModule', [])
.service('MyController', ['$scope', function($scope) {
// This controller throws an unknown provider error because
// a scope object cannot be injected into a service.
}]);
For larger s&r tasks it's better and faster to use grep and xargs, so, for example;
grep -rl 'apples' /dir_to_search_under | xargs sed -i 's/apples/oranges/g'

You may be overcomplicating things, is there any reason you need the stringr package?
df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
as.Date(df$Date, "%m/%d/%Y %H:%M:%S")
[1] "2009-10-09" "2009-10-15"
More generally and if you need the time component as well, use strptime:
strptime(df$Date, "%m/%d/%Y %H:%M:%S")
I'm guessing at what your actual data might look at from the partial results you give.
onclick="window.open('your_html', '_blank')"
From Spring 3, all the resources needs to mapped in a different way. You need to use the tag to specify the location of the resources.
Example :
<mvc:resources mapping="/resources/**" location="/resources/" />
By doing this way, you are directing the dispatcher servlet to look into the directory resources to look for the static content.
The easiest way to reuse the StringBuffer
is to use the method setLength()
public void setLength(int newLength)
You may have the case like
StringBuffer sb = new StringBuffer("HelloWorld");
// after many iterations and manipulations
sb.setLength(0);
// reuse sb
Easy way with commons-io.
IOUtils.toString(request.getReader());

I just renamed the package and it worked for me.
Or if you are using Ionic, you could delete the application and try again, this happens when ionic detects that the app you are deploying is not coming from the same build. It often happen when you change from pc.
I ran into an issue where I have multiple node servers running, and I want to just kill one of them and redeploy it from a script.
Note: This example is in a bash shell on Mac.
To do so I make sure to make my node
call as specific as possible. For example rather than calling node server.js
from the apps directory, I call node app_name_1/app/server.js
Then I can kill it using:
kill -9 $(ps aux | grep 'node\ app_name_1/app/server.js' | awk '{print $2}')
This will only kill the node process running app_name_1/app/server.js.
If you ran node app_name_2/app/server.js
this node process will continue to run.
If you decide you want to kill them all you can use killall node
as others have mentioned.
This is because you are reading a cursor, not an array. This means that you are reading sequentially through the results and when you get to the end you would need to reset the cursor to the beginning of the results to read them again.
If you did want to read over the results multiple times, you could use fetchAll to read the results into a true array and then it would work as you are expecting.
a few other managed wrappers for you to check out
Writing your own interop wrappers can be a time-consuming and difficult process in .NET. There are some advantages to writing a C++ library for the interop - particularly as it allows you to greatly simplify the interface that the C# code. However, if you are only needing a subset of the library, it might make your life easier to just do the interop in C#.
ViewGroup class provides API for child views management in run-time, allowing to add/remove views as well.

As mentioned, sealed
is an equivalent of final
for methods and classes.
As for the rest, it is complicated.
For static final
fields, static readonly
is the closest thing possible. It allows you to initialize the static field in a static constructor, which is fairly similar to static initializer in Java. This applies both to constants (primitives and immutable objects) and constant references to mutable objects.
The const
modifier is fairly similar for constants, but you can't set them in a static constructor.
On a field that shouldn't be reassigned once it leaves the constructor, readonly
can be used. It is not equal though - final
requires exactly one assignment even in constructor or initializer.
There is no C# equivalent for a final
local variable that I know of. If you are wondering why would anyone need it: You can declare a variable prior to an if-else, switch-case or so. By declaring it final, you enforce that it is assigned at most once.
Java local variables in general are required to be assigned at least once before they are read. Unless the branch jumps out before value read, a final variable is assigned exactly once. All of this is checked compile-time. This requires well behaved code with less margin for an error.
Summed up, C# has no direct equivalent of final
. While Java lacks some nice features of C#, it is refreshing for me as mostly a Java programmer to see where C# fails to deliver an equivalent.
You could define controller at the <html>
level.
<html ng-app="app" ng-controller="titleCtrl">
<head>
<title>{{ Page.title() }}</title>
...
You create service: Page
and modify from controllers.
myModule.factory('Page', function() {
var title = 'default';
return {
title: function() { return title; },
setTitle: function(newTitle) { title = newTitle }
};
});
Inject Page
and Call 'Page.setTitle()' from controllers.
Here is the concrete example: http://plnkr.co/edit/0e7T6l
I just wanted to contribute this should someone be looking for help with adding separators between the strings, depending on whether a field is NULL or not.
So in the example of creating a one line address from separate fields
Address1, Address2, Address3, City, PostCode
in my case, I have the following Calculated Column which seems to be working as I want it:
case
when [Address1] IS NOT NULL
then ((( [Address1] +
isnull(', '+[Address2],'')) +
isnull(', '+[Address3],'')) +
isnull(', '+[City] ,'')) +
isnull(', '+[PostCode],'')
end
Hope that helps someone!
You can set timeout like this,
con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);
With large arrays, print_r can show far more information than is useful. You can truncate it like this, showing the first 2000 characters or however many you need.
echo "<pre>" . substr(print_r($dataset, 1), 0, 2000) . "</pre>";
tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.
If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.
The RequestContext
is deprecated from Primefaces 6.2. From this version use the following:
if (componentID != null && PrimeFaces.current().isAjaxRequest()) {
PrimeFaces.current().ajax().update(componentID);
}
And to execute javascript from the backbean use this way:
PrimeFaces.current().executeScript(jsCommand);
vw and vh stand for viewport width and viewport height respectively.
The difference between using width: 100vw
instead of width: 100%
is that while 100%
will make the element fit all the space available, the viewport width has a specific measure, in this case the width of the available screen, including the document margin.
If you set the style body { margin: 0 }
, 100vw should behave the same as 100%.
Using vw
as unit for everything in your website, including font sizes and heights, will make it so that the site is always displayed proportionally to the device's screen width regardless of it's resolution. This makes it super easy to ensure your website is displayed properly in both workstation and mobile.
You can set font-size: 1vw
(or whatever size suits your project) in your body
CSS and everything specified in rem
units will automatically scale according to the device screen, so it's easy to port existing projects and even frameworks (such as Bootstrap) to this concept.
After coming back to my own question after 5 year and seeing so many people found this useful, a little update.
A string variable can be split into a list
by using the split function (it can contain similar values, set
is for the assignment) . I haven't found this function in the official documentation but it works similar to normal Python. The items can be called via an index, used in a loop or like Dave suggested if you know the values, it can set variables like a tuple.
{% set list1 = variable1.split(';') %}
The grass is {{ list1[0] }} and the boat is {{ list1[1] }}
or
{% set list1 = variable1.split(';') %}
{% for item in list1 %}
<p>{{ item }}<p/>
{% endfor %}
or
{% set item1, item2 = variable1.split(';') %}
The grass is {{ item1 }} and the boat is {{ item2 }}

Open a command prompt as an Administrator.
Enter slmgr /upk
and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
Enter slmgr /cpky
and wait for this to complete. This will remove the product key from the registry if it's still there.
Enter slmgr /rearm
and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.
This should put the system back to a pre-key state.
Hope this helps you out!
Why not just use the Count property on the List?
for(int cnt3 = 0; cnt3 < integerList.Count; cnt3++)
This command worked for me,
sudo chown -v $USER ~/.ssh/known_hosts
as mentioned by @kenorb.
The error was coming due to broken permissions, for the current user.
i have the same problem. this is how i fixed the problem. first when the error is occurred, my array data is coming form DB like this --,
{brands: Array(5), _id: "5ae9455f7f7af749cb2d3740"}
make sure that your data is an ARRAY, not an OBJECT that carries an array. only array look like this --,
(5) [{…}, {…}, {…}, {…}, {…}]
it solved my problem.
min-width
and max-width
properties do not work the way you expect for table cells. From spec:
In CSS 2.1, the effect of 'min-width' and 'max-width' on tables, inline tables, table cells, table columns, and column groups is undefined.
This hasn't changed in CSS3.
<input type="radio" name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >

$("#submit").click(function() {
alert($('input[name=s_2_1_6_0]:checked').val());
});

tl;dr
cp -R "/src/project 1/App" "/src/project 2"
Explanation:
Using quotes will cater for spaces in the directory names
cp -R "/src/project 1/App" "/src/project 2"
If the App directory is specified in the destination directory:
cp -R "/src/project 1/App" "/src/project 2/App"
and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"
Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.
Inside a bash script:
cp -R "${1}/App" "${2}"
If you want to download an image from https:
$output_filename = 'output.png';
$host = "https://.../source.png"; // <-- Source image url (FIX THIS)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // <-- don't forget this
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // <-- and this
$result = curl_exec($ch);
curl_close($ch);
$fp = fopen($output_filename, 'wb');
fwrite($fp, $result);
fclose($fp);
Old question, but I just wanted to tack on my solution. This one doesn't require any strange shell tricks, or rely on something that hasn't been around forever.
if [ -n "$(printf '%s\n' "$var" | sed 's/[0-9]//g')" ]; then
echo 'is not numeric'
else
echo 'is numeric'
fi
Basically it just removes all digits from the input, and if you're left with a non-zero-length string then it wasn't a number.

Like this:
@Html.DropDownListFor(model => model.Status, new List<SelectListItem>
{ new SelectListItem{Text="Active", Value="True"},
new SelectListItem{Text="Deactive", Value="False"}},"Select One")
If you want Active to be selected by default then use Selected
property of SelectListItem
:
@Html.DropDownListFor(model => model.Status, new List<SelectListItem>
{ new SelectListItem{Text="Active", Value="True",Selected=true},
new SelectListItem{Text="Deactive", Value="False"}},"Select One")
If using SelectList
, then you have to use this overload and specify SelectListItem
Value
property which you want to set selected:
@Html.DropDownListFor(model => model.title,
new SelectList(new List<SelectListItem>
{
new SelectListItem { Text = "Active" , Value = "True"},
new SelectListItem { Text = "InActive", Value = "False" }
},
"Value", // property to be set as Value of dropdown item
"Text", // property to be used as text of dropdown item
"True"), // value that should be set selected of dropdown
new { @class = "form-control" })
This code nearly worked for me...but I wanted a multiple element filter so my mods to the filter pipe are below:
import { Pipe, PipeTransform, Injectable } from '@angular/core';
@Pipe({ name: 'jsonFilterBy' })
@Injectable()
export class JsonFilterByPipe implements PipeTransform {
transform(json: any[], args: any[]): any[] {
const searchText = args[0];
const jsonKey = args[1];
let jsonKeyArray = [];
if (searchText == null || searchText === 'undefined') { return json; }
if (jsonKey.indexOf(',') > 0) {
jsonKey.split(',').forEach( function(key) {
jsonKeyArray.push(key.trim());
});
} else {
jsonKeyArray.push(jsonKey.trim());
}
if (jsonKeyArray.length === 0) { return json; }
// Start with new Array and push found objects onto it.
let returnObjects = [];
json.forEach( function ( filterObjectEntry ) {
jsonKeyArray.forEach( function (jsonKeyValue) {
if ( typeof filterObjectEntry[jsonKeyValue] !== 'undefined' &&
filterObjectEntry[jsonKeyValue].toLowerCase().indexOf(searchText.toLowerCase()) > -1 ) {
// object value contains the user provided text.
returnObjects.push(filterObjectEntry);
}
});
});
return returnObjects;
}
}
Now, instead of
jsonFilterBy:[ searchText, 'name']
you can do
jsonFilterBy:[ searchText, 'name, other, other2...']
I would use
like 'Express Edition%'
Example:
DECLARE @edition varchar(50);
set @edition = cast((select SERVERPROPERTY ('edition')) as varchar)
DECLARE @isExpress bit
if @edition like 'Express Edition%'
set @isExpress = 1;
else
set @isExpress = 0;
print @isExpress
I simply created a file called code:
#!/bin/bash
open /Applications/Visual\ Studio\ Code.app $1
Make it executable:
$ chmod 755 code
Then put that in /usr/local/bin
$ sudo mv code /usr/local/bin
As long as the file sits someplace that is in your path you can open a file by just typing: code
If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:
public function scopeLike($query, $field, $value){
return $query->where($field, 'LIKE', "%$value%");
}
So then you can use this method in such way:
User::like('name', 'Tomas')->get();
The problem arises when a different system grabs the $ variable. You have multiple $ variables being used as objects from multiple libraries, resulting in the error.
To solve it, use jQuery.noConflict just before your (function($){
:
jQuery.noConflict();
(function($){
$.fn.pluginbutton = function (options) {
...
This is a variation on the answer above by @mtomis.
It creates a stream of lines. It emits 'data' and 'end' events, allowing you to handle the end of the stream.
var events = require('events');
var LineStream = function (input) {
var remaining = '';
input.on('data', function (data) {
remaining += data;
var index = remaining.indexOf('\n');
var last = 0;
while (index > -1) {
var line = remaining.substring(last, index);
last = index + 1;
this.emit('data', line);
index = remaining.indexOf('\n', last);
}
remaining = remaining.substring(last);
}.bind(this));
input.on('end', function() {
if (remaining.length > 0) {
this.emit('data', remaining);
}
this.emit('end');
}.bind(this));
}
LineStream.prototype = new events.EventEmitter;
Use it as a wrapper:
var lineInput = new LineStream(input);
lineInput.on('data', function (line) {
// handle line
});
lineInput.on('end', function() {
// wrap it up
});
for followers, this error message can also mean "you have it referencing a foreign object that hasn't been saved to the DB yet" (even though it's there, and is non null).
I came across several answers in SO and at the end I realized that my error was that I had misspelled "Html.TextBoxFor." In my case what I wrote was "Html.TextboxFor." I did not uppercase the B in TextBoxFor. Fixed that and voilà. Problem solved. I hope this helps someone.
Quick Fix: I have the same problem to start the MongoDB and it was
easily fixed by running the file mongod.exe
(C:\Program Files\MongoDB\Server\3.2\bin
) then run the file mongo.exe
(C:\Program Files\MongoDB\Server\3.2\bin
)..Problem fixed
Here's a quick way to get what is happening:
When you did the following:
name? : string
You were saying to TypeScript it was optional. Nevertheless, when you did:
let name1 : string = person.name; //<<<Error here
You did not leave it a choice. You needed to have a Union on it reflecting the undefined type:
let name1 : string | undefined = person.name; //<<<No error here
Using your answer, I was able to sketch out the following which is basically, an Interface, a Class and an Object. I find this approach simpler, never mind if you don't.
// Interface
interface iPerson {
fname? : string,
age? : number,
gender? : string,
occupation? : string,
get_person?: any
}
// Class Object
class Person implements iPerson {
fname? : string;
age? : number;
gender? : string;
occupation? : string;
get_person?: any = function () {
return this.fname;
}
}
// Object literal
const person1 : Person = {
fname : 'Steve',
age : 8,
gender : 'Male',
occupation : 'IT'
}
const p_name: string | undefined = person1.fname;
// Object instance
const person2: Person = new Person();
person2.fname = 'Steve';
person2.age = 8;
person2.gender = 'Male';
person2.occupation = 'IT';
// Accessing the object literal (person1) and instance (person2)
console.log('person1 : ', p_name);
console.log('person2 : ', person2.get_person());
In the head add this
//Include jQuery
<meta id="Viewport" name="viewport" content="initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no">
<script type="text/javascript">
$(function(){
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent) ) {
var ww = ( $(window).width() < window.screen.width ) ? $(window).width() : window.screen.width; //get proper width
var mw = 480; // min width of site
var ratio = ww / mw; //calculate ratio
if( ww < mw){ //smaller than minimum size
$('#Viewport').attr('content', 'initial-scale=' + ratio + ', maximum-scale=' + ratio + ', minimum-scale=' + ratio + ', user-scalable=yes, width=' + ww);
}else{ //regular size
$('#Viewport').attr('content', 'initial-scale=1.0, maximum-scale=2, minimum-scale=1.0, user-scalable=yes, width=' + ww);
}
}
});
</script>
As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.
It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.
library(grid)
library(gridExtra)
library(plyr)
# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))
# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") +
xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category))
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") +
labs(title = "Proportion of total Frequency accounted by each Category in given Year")
# bring them together
grid.arrange(totals,proportion)
This will give you a 2 panel display like this:
If you want to add Frequency values a table is the best format.
You could also use Hex Color Code,
Name Hex Color Code RGB Color Code
Red #FF0000 rgb(255, 0, 0)
Maroon #800000 rgb(128, 0, 0)
Yellow #FFFF00 rgb(255, 255, 0)
Olive #808000 rgb(128, 128, 0)
For example
import matplotlib.pyplot as plt
import random
number_of_colors = 8
color = ["#"+''.join([random.choice('0123456789ABCDEF') for j in range(6)])
for i in range(number_of_colors)]
print(color)
['#C7980A', '#F4651F', '#82D8A7', '#CC3A05', '#575E76', '#156943', '#0BD055', '#ACD338']
Lets try plotting them in a scatter plot
for i in range(number_of_colors):
plt.scatter(random.randint(0, 10), random.randint(0,10), c=color[i], s=200)
plt.show()
if use Inline CSS you use
<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>
Otherwise you can use class properties which related with a separate css file (styling your website) as like In CSS File
.imgSize {height:100px;width:100px;}
In HTML File
<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>
Sure, you can open the devtools with Ctrl+Shift+I, and then click the inspect element button (square with the arrow)
I was lead here in my Google searching. In a show of good faith I have included what I pieced together from parts of this code and other code I've gathered along the way.

in Eike Thies's response above, if we use underscore.js, filter could be simplified to :
var app = angular.module('myApp', []).filter('object2Array', function() {
return function(input) {
return _.toArray(input);
}
});
Try this:
UPDATE test
SET
field = 1
WHERE id = 123 and condition
It looks like you are trying to parse each line. You've been shown by another answer how to use getline
in a loop to seperate each line. The other tool you are going to want is istringstream
, to seperate each token.
std::string line;
while(std::getline(file, line))
{
std::istringstream iss(line);
std::string token;
while (iss >> token)
{
// do something with token
}
}
It may be worth noting that auto-indent does not work if there are syntax errors in the document. Get rid of the red squigglies, and THEN try CTRL+K, CTRL+D, whatever...
This is actually not an error... What happens here is that Mongo relies on a daemon in order to run the local database server, so in order to "fire up" the mongo server in your shell, you have to start the mongo service first.
For Fedora Linux (wich is the Distro I use) You have to run these commands:
1 sudo service mongod start
2 mongo
And there you have it! the server is going to run. Now, If you want Mongo service to Start when the system boots then you have to run:
sudo chkconfig --levels 235 mongod on
And that's all! If you do that, now in the shell you just have to type mongo in order to start the server but that's pretty much it, the problem is you have to start the SERVICE first and then the SERVER :)
P.S. The commands I posted might work on other linux distros as well, not just in fedora... In case not maybe you have to tweak some words depending on the distro you're using ;)

I know this question has already been marked as answered, but let me plug my own library here. It's called inspect.lua, and you can find it here:
https://github.com/kikito/inspect.lua
It's just a single file that you can require from any other file. It returns a function that transforms any Lua value into a human-readable string:
local inspect = require('inspect')
print(inspect({1,2,3})) -- {1, 2, 3}
print(inspect({a=1,b=2})
-- {
-- a = 1
-- b = 2
-- }
It indents subtables properly, and handles "recursive tables" (tables that contain references to themselves) correctly, so it doesn't get into infinite loops. It sorts values in a sensible way. It also prints metatable information.
Regards!
I noticed huge memory leak & performance difference between insertAfter
& after
or insertBefore
& before
.. If you have tons of DOM elements, or you need to use after()
or before()
inside a MouseMove event, the browser memory will probably increase and next operations will run really slow.
The solution I've just experienced is to use inserBefore instead before()
and insertAfter instead after()
.
In practical terms, don't do that.
Instead add a button with Custom style (no button graphics unless you specify images) over the UIImageView. Then attach whatever methods you want called to that.
You can use that technique for many cases where you really want some area of the screen to act as a button instead of messing with the Touch stuff.
@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.

To stop the window being resizeable once you've maximised it you need to change the FormBorderStyle
from Sizable
to one of the fixed constants:
FixedSingle
Fixed3D
FixedDialog
From the MSDN Page Remarks section:
The border style of the form determines how the outer edge of the form appears. In addition to changing the border display for a form, certain border styles prevent the form from being sized. For example, the FormBorderStyle.FixedDialog border style changes the border of the form to that of a dialog box and prevents the form from being resized. The border style can also affect the size or availability of the caption bar section of a form.
It will change the appearance of the form if you pick Fixed3D
for example, and you'll probably have to do some work if you want the form to restore to non-maximised and be resizeable again.
I recommend Google protocol buffers. I had the chance to test drive the library on a new project and it's remarkably easy to use. The library is heavily optimized for performance.
Protobuf is different than other serialization solutions mentioned here in the sense that it does not serialize your objects, but rather generates code for objects that are serialization according to your specification.
With SQL server 2008 and more, using this query:

If you need change slider values from several input, use it:

<input type="text" id="amount2">
<div id="slider-range"></div>
js:
$( "#slider-range" ).slider({
range: true,
min: 0,
max: 217,
values: [ 0, 217 ],
slide: function( event, ui ) {
$( "#amount" ).val( ui.values[ 0 ] );
$( "#amount2" ).val( ui.values[ 1 ] );
}
});
$("#amount").change(function() {
$("#slider-range").slider('values',0,$(this).val());
});
$("#amount2").change(function() {
$("#slider-range").slider('values',1,$(this).val());
});
Toolbar toolbar = findViewById(R.id.myToolbar);

The error is here:
hasLetter("a",words[]);
You are passing the first item of words
, instead of the array.
Instead, pass the array to the function:
hasLetter("a",words);
Problem solved!
Here's a breakdown of what the problem was:
I'm guessing in your browser (chrome throws a different error), words[] == words[0]
, so when you call hasLetter("a",words[]);
, you are actually calling hasLetter("a",words[0]);
. So, in essence, you are passing the first item of words to your function, not the array as a whole.
Of course, because words
is just an empty array, words[0]
is undefined
. Therefore, your function call is actually:
hasLetter("a", undefined);
which means that, when you try to access d[ascii]
, you are actually trying to access undefined[0]
, hence the error.
To check for a timeout, I believe you check the value of ex.Number. If it is -2, then you have a timeout situation.
-2 is the error code for timeout, returned from DBNETLIB, the MDAC driver for SQL Server. This can be seen by downloading Reflector, and looking under System.Data.SqlClient.TdsEnums for TIMEOUT_EXPIRED.
Your code would read:
if (ex.Number == -2)
{
//handle timeout
}
Code to demonstrate failure:
try
{
SqlConnection sql = new SqlConnection(@"Network Library=DBMSSOCN;Data Source=YourServer,1433;Initial Catalog=YourDB;Integrated Security=SSPI;");
sql.Open();
SqlCommand cmd = sql.CreateCommand();
cmd.CommandText = "DECLARE @i int WHILE EXISTS (SELECT 1 from sysobjects) BEGIN SELECT @i = 1 END";
cmd.ExecuteNonQuery(); // This line will timeout.
cmd.Dispose();
sql.Close();
}
catch (SqlException ex)
{
if (ex.Number == -2) {
Console.WriteLine ("Timeout occurred");
}
}
I have a .bat file on my quick task bar (windows) with:

John is an optional Person, meaning it can hold a value or be nil.
john.apartment = number73
is used if john is not an optional. Since john is never nil we can be sure it won't call apartment on a nil value. While
john!.apartment = number73
promises the compiler that john is not nil then unwraps the optional to get john's value and accesses john's apartment property. Use this if you know that john is not nil. If you call this on a nil optional, you'll get a runtime error.
The documentation includes a nice example for using this where convertedNumber is an optional.
if convertedNumber {
println("\(possibleNumber) has an integer value of \(convertedNumber!)")
} else {
println("\(possibleNumber) could not be converted to an integer")
}
One line answer:
return LocalDate.parse("06/02/2018",DateTimeFormatter.ofPattern("dd/MM/yyyy")).getDayOfWeek().name();
Usage Example:
public static String getDayOfWeek(String date){
return LocalDate.parse(date, DateTimeFormatter.ofPattern("dd/MM/yyyy")).getDayOfWeek().name();
}
public static void callerMethod(){
System.out.println(getDayOfWeek("06/02/2018")); //TUESDAY
}
After trying all of the fixes with no cigar I fixed it by updating this Nuget Package in Visual Studios:
Microsoft.CodeDom.Providers.DotNetCompilerPlatform
Mine was from 1.0.0 to 2.0.0 for reference (The error no longer shows)
This will also give you the project directory by navigating two levels up from the current executing directory (this won't return the project directory for every build, but this is the most common).
System.IO.Path.GetFullPath(@"..\..\")
Of course you would want to contain this inside some sort of validation/error handling logic.
I find it important to note that python 3 defines the opening modes differently to the answers here that were correct for Python 2.
The Pyhton 3 opening modes are:
'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
----
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newlines mode (for backwards compatibility; should not be used in new code)
The modes r
, w
, x
, a
are combined with the mode modifiers b
or t
. +
is optionally added, U
should be avoided.
As I found out the hard way, it is a good idea to always specify t
when opening a file in text mode since r
is an alias for rt
in the standard open()
function but an alias for rb
in the open()
functions of all compression modules (when e.g. reading a *.bz2
file).
Thus the modes for opening a file should be:
rt
/ wt
/ xt
/ at
for reading / writing / creating / appending to a file in text mode and
rb
/ wb
/ xb
/ ab
for reading / writing / creating / appending to a file in binary mode.
Use +
as before.
The pair RegOpenKey and RegQueryKeyEx will do the trick.
If you use MFC CRegKey class is even more easier solution.
I've coded up a simple example for you and annotated the source. The example shows how to grab live json and parse into a JSONObject
for detail extraction:
try{
// Create a new HTTP Client
DefaultHttpClient defaultClient = new DefaultHttpClient();
// Setup the get request
HttpGet httpGetRequest = new HttpGet("http://example.json");
// Execute the request in the client
HttpResponse httpResponse = defaultClient.execute(httpGetRequest);
// Grab the response
BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
// Instantiate a JSON object from the request response
JSONObject jsonObject = new JSONObject(json);
} catch(Exception e){
// In your production code handle any errors and catch the individual exceptions
e.printStackTrace();
}
Once you have your JSONObject
refer to the SDK for details on how to extract the data you require.
If you want to do it by ClassName you could do:
<script type="text/javascript">
function hideTd(className){
var elements;
if (document.getElementsByClassName)
{
elements = document.getElementsByClassName(className);
}
else
{
var elArray = [];
var tmp = document.getElementsByTagName(elements);
var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
for ( var i = 0; i < tmp.length; i++ ) {
if ( regex.test(tmp[i].className) ) {
elArray.push(tmp[i]);
}
}
elements = elArray;
}
for(var i = 0, i < elements.length; i++) {
if( elements[i].textContent == ''){
elements[i].style.display = 'none';
}
}
}
</script>
One-liner solution as of 2020, if your data is not meant to be sent as multipart/form-data
or application/x-www-form-urlencoded
:
<form onsubmit='return false'>
<!-- ... -->
</form>
To escape it, double the quotes:
INSERT INTO TABLE_A VALUES ( 'Alex''s Tea Factory' );

There is a plugin for jQuery called inview which adds a new "inview" event.
Here is some code for a jQuery plugin that doesn't use events:
$.extend($.expr[':'],{
inView: function(a) {
var st = (document.documentElement.scrollTop || document.body.scrollTop),
ot = $(a).offset().top,
wh = (window.innerHeight && window.innerHeight < $(window).height()) ? window.innerHeight : $(window).height();
return ot > st && ($(a).height() + ot) < (st + wh);
}
});
(function( $ ) {
$.fn.inView = function() {
var st = (document.documentElement.scrollTop || document.body.scrollTop),
ot = $(this).offset().top,
wh = (window.innerHeight && window.innerHeight < $(window).height()) ? window.innerHeight : $(window).height();
return ot > st && ($(this).height() + ot) < (st + wh);
};
})( jQuery );
I found this in a comment here ( http://remysharp.com/2009/01/26/element-in-view-event-plugin/ ) by a bloke called James
Push always unique value in array
ab = [
{"id":"1","val":"value1"},
{"id":"2","val":"value2"},
{"id":"3","val":"value3"}
];
var clickId = [];
var list = JSON.parse(ab);
$.each(list, function(index, value){
if(clickId.indexOf(value.id) < 0){
clickId.push(value.id);
}
});
int arsize(int st1[]) {
int i = 0;
for (i; !(st1[i] & (1 << 30)); i++);
return i;
}
This works for me :)
Not a specific answer to your question but I had got this error when I hadn't set an initial value for an enum while declaring it as a property. I assigned a initial value to the enum to resolve this error. Posting here as it might help someone.
I came across this, and my issue was using an older version of node (3.X), when a newer version was required.
The error message actually suggested this as well:
...
Make sure you have the latest version of node.js and npm installed
...
So the solution may be as simple as upgrading node/npm. You can easily do this using nvm, the "Node Version Manager"
After you've installed nvm
, you can install and use the latest version of node by simply running this command:
nvm install node
For example:
$ nvm install node

This occurred for me due to changing the names of certain dataset fields within BIDS that were being referenced by parameters. I forgot to go into the parameters and reassign a default value (the default value of the parameter didn't automatically change to the newly renamed dataset field. Instead .
My 2 cents,
I was having a similar problem while trying to get a (Visual Studio 2013) Diagnostics Report in x64 Release Mode (CPU Sampling) and while the symbols for the needed dll files were loaded, the symbols for my executable would fail to load.
I didn't change anything in the Symbols menu, I instead made some changes within the Property Pages of my executable's thread in the Solution Explorer, namely
Configuration Properties / General / Enable Managed Incremental Build to YES
Configuration Properties / Debugging / Merge Environment to NO
Configuration Properties / C/C++ / Enable Browse Information to YES (/FR)
Configuration Properties / Linker / Enable Incremental Linking to YES (/INCREMENTAL)
EDIT : This last one does the trick
....
Configuration Properties / Linker / Debugging / Generate Debug Info to Yes (/DEBUG)
....
After that it worked and it loaded the symbols fine. I'm sure one or more of the above did the trick for me (although I'm not sure exactly which) and just want to let others know and try this..
peace
when you try to change targetSDKVersion 26 to 25 that time occurred i was found solution of No resource found that matches the given name: attr 'android:keyboardNavigationCluster'. when updating to Support Library 26.0.0
Just Chage This code from Your Build.gradle

if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {

System.out.println(myList.size());
Since no elements are in the list
output => 0
myList.add("newString"); // use myList.add() to insert elements to the arraylist
System.out.println(myList.size());
Since one element is added to the list
output => 1
Okay, so I figured out what the problem was, and the approach I believe works best. In my case, because the two objects weren't identical from a Javascript perspective, as in: they may have shared the same values, but they were different actual objects, e.g. originalObject
was instantiated entirely separately from objects
which was essentially an array of reference data (to populate the dropdown).
I found that the approach that worked best for me was to compare a unique property of the objects, rather than directly compare the two entire objects. This comparison is done in the bound property selected
:
<select [ngModel]="originalObject">
<option *ngFor="let object of objects" [ngValue]="object" [selected]="object.uniqueId === originalObject.uniqueId">{{object.name}}</option>
</select>
If, like me, you're configuring Heroku to run a script from your package.json
file on deploy, make sure you haven't hard-coded the value of PORT
in that script! If you do, you'll end up like me and spend an hour trying to figure out why you're getting this error.
To add interceptor to a spring boot application, do the following
Create an interceptor class
public class MyCustomInterceptor implements HandlerInterceptor{
//unimplemented methods comes here. Define the following method so that it
//will handle the request before it is passed to the controller.
@Override
public boolean preHandle(HttpServletRequest request,HttpServletResponse response){
//your custom logic here.
return true;
}
}
Define a configuration class
@Configuration
public class MyConfig extends WebMvcConfigurerAdapter{
@Override
public void addInterceptors(InterceptorRegistry registry){
registry.addInterceptor(new MyCustomInterceptor()).addPathPatterns("/**");
}
}
Thats it. Now all your requests will pass through the logic defined under preHandle() method of MyCustomInterceptor.
Please make sure you have downloaded the sqldump fully, this problem is very common when we try to import half/incomplete downloaded sqldump. Please check size of your sqldump file.
Summing up what the others have suggested, and adding a third way
You can:
df.assign(Name='abc')
access the new column series (it will be created) and set it:
df['Name'] = 'abc'
insert(loc, column, value, allow_duplicates=False)
df.insert(0, 'Name', 'abc')
where the argument loc ( 0 <= loc <= len(columns) ) allows you to insert the column where you want.
'loc' gives you the index that your column will be at after the insertion. For example, the code above inserts the column Name as the 0-th column, i.e. it will be inserted before the first column, becoming the new first column. (Indexing starts from 0).
All these methods allow you to add a new column from a Series as well (just substitute the 'abc' default argument above with the series).
