Here is a good tutorial with code. Let me know if it works for you! This is also a good tutorial.
EDIT
In This example, all you need to do is add this line:
gallery.setSelection(1);
after setting the adapter to gallery object, that is this line:
gallery.setAdapter(new ImageAdapter(this));
UPDATE1
Alright, I got your problem. This open source library is your solution. I also have used it for one of my projects. Hope this will solve your problem finally.
UPDATE2:
I would suggest you to go through this tutorial. You might get idea. I think I got your problem, you want the horizontal scrollview with snap. Try to search with that keyword on google or out here, you might get your solution.
public class EMView extends Activity {
ImageView img,img1;
int column_index;
Intent intent=null;
// Declare our Views, so we can access them later
String logo,imagePath,Logo;
Cursor cursor;
//YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int SELECT_PICTURE = 1;
String selectedImagePath;
//ADDED
String filemanagerstring;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img= (ImageView)findViewById(R.id.gimg1);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
//UPDATED
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
imagePath.getBytes();
TextView txt = (TextView)findViewById(R.id.title);
txt.setText(imagePath.toString());
Bitmap bm = BitmapFactory.decodeFile(imagePath);
// img1.setImageBitmap(bm);
}
}
}
//UPDATED!
public String getPath(Uri uri) {
String[] projection = { MediaColumns.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
column_index = cursor
.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
imagePath = cursor.getString(column_index);
return cursor.getString(column_index);
}
}
Just wanted to say that this answer is brilliant and I'm using it for a long time without problems. But some time ago I've stumbled upon a problem that DownloadsProvider returns URIs in format content://com.android.providers.downloads.documents/document/raw%3A%2Fstorage%2Femulated%2F0%2FDownload%2Fdoc.pdf
and hence app is crashed with NumberFormatException
as it's impossible to parse its uri segments as long. But raw:
segment contains direct uri which can be used to retrieve a referenced file. So I've fixed it by replacing isDownloadsDocument(uri)
if
content with following:
final String id = DocumentsContract.getDocumentId(uri);
if (!TextUtils.isEmpty(id)) {
if (id.startsWith("raw:")) {
return id.replaceFirst("raw:", "");
}
try {
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
} catch (NumberFormatException e) {
Log.e("FileUtils", "Downloads provider returned unexpected uri " + uri.toString(), e);
return null;
}
}
Building upon David's answer, my two pennies on the onActivityResult()
part. It takes care of the changes introduced in 5.1.1 and detects whether the user has picked a single or multiple image from the library.
private enum Outcome {
camera, singleLibrary, multipleLibrary, unknown
}
/**
* Returns a List<Uri> containing the image uri(s) chosen by the user
*
* @param data The data intent coming from the onActivityResult()
* @param cameraUri The uri that had been passed to the intent when the chooser was invoked.
* @return A List<Uri>, never null.
*/
public List<Uri> getPicturesUriFromIntent(Intent data, Uri cameraUri) {
Outcome outcome = Outcome.unknown;
if (data == null || (data.getData() == null && data.getClipData() == null)) {
outcome = Outcome.camera;
} else if (data.getData() != null && data.getClipData() == null) {
outcome = Outcome.singleLibrary;
} else if (data.getData() == null) {
outcome = Outcome.multipleLibrary;
} else {
final String action = data.getAction();
if (action != null && action.equals(MediaStore.ACTION_IMAGE_CAPTURE)) {
outcome = Outcome.camera;
}
}
// list the uri(s) we got back
List<Uri> uris = new ArrayList<>();
switch (outcome) {
case camera:
uris.add(cameraUri);
break;
case singleLibrary:
uris.add(data.getData());
break;
case multipleLibrary:
final ClipData clipData = data.getClipData();
for (int i = 0; i < clipData.getItemCount(); i++) {
ClipData.Item item = clipData.getItemAt(i);
uris.add(item.getUri());
}
break;
}
return uris;
}
view.isVisible = true
view.isInvisible = true
view.isGone = true
// For these to work, you need to use androidx and import:
import androidx.core.view.isVisible // or isInvisible/isGone
If you'd like them to be more consistent length, work for nullable views, and lower the chance of writing the wrong boolean, try using these custom extensions:
// Example
view.hide()
fun View?.show() {
if (this == null) return
if (!isVisible) isVisible = true
}
fun View?.hide() {
if (this == null) return
if (!isInvisible) isInvisible = true
}
fun View?.gone() {
if (this == null) return
if (!isGone) isGone = true
}
To make conditional visibility simple, also add these:
fun View?.show(visible: Boolean) {
if (visible) show() else gone()
}
fun View?.hide(hide: Boolean) {
if (hide) hide() else show()
}
fun View?.gone(gone: Boolean = true) {
if (gone) gone() else show()
}
Like this:
document.getElementById('myTextarea').value = '';
or like this in jQuery:
$('#myTextarea').val('');
Where you have
<textarea id="myTextarea" name="something">This text gets removed</textarea>
For all the downvoters and non-believers:
value Property: Retrieves or sets the text in the entry field of the textArea element.
value DOMString The raw value contained in the control.
Below is the link that suggests how to design Splash screen. To avoid white/black background we need to define a theme with splash background and set that theme to splash in manifest file.
https://android.jlelse.eu/right-way-to-create-splash-screen-on-android-e7f1709ba154
splash_background.xml inside res/drawable folder
<?xml version=”1.0" encoding=”utf-8"?>
<layer-list xmlns:android=”http://schemas.android.com/apk/res/android">
<item android:drawable=”@color/colorPrimary” />
<item>
<bitmap
android:gravity=”center”
android:src=”@mipmap/ic_launcher” />
</item>
</layer-list>
Add below styles
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<!-- Splash Screen theme. -->
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/splash_background</item>
</style>
In Manifest set theme as shown below
<activity
android:name=".SplashActivity"
android:theme="@style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
You'll have to use an HttpServletRequestWrapper:
public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain) throws IOException, ServletException {
final HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletRequestWrapper wrapper = new HttpServletRequestWrapper(httpRequest) {
@Override
public String getHeader(String name) {
final String value = request.getParameter(name);
if (value != null) {
return value;
}
return super.getHeader(name);
}
};
chain.doFilter(wrapper, response);
}
Depending on what you want to do you may need to implement other methods of the wrapper like getHeaderNames
for instance. Just be aware that this is trusting the client and allowing them to manipulate any HTTP header. You may want to sandbox it and only allow certain header values to be modified this way.
If the data is a static or global variable, it is zero-filled by default, so just declare it myStruct _m;
If the data is a local variable or a heap-allocated zone, clear it with memset
like:
memset(&m, 0, sizeof(myStruct));
Current compilers (e.g. recent versions of gcc
) optimize that quite well in practice. This works only if all zero values (include null pointers and floating point zero) are represented as all zero bits, which is true on all platforms I know about (but the C standard permits implementations where this is false; I know no such implementation).
You could perhaps code myStruct m = {};
or myStruct m = {0};
(even if the first member of myStruct
is not a scalar).
My feeling is that using memset
for local structures is the best, and it conveys better the fact that at runtime, something has to be done (while usually, global and static data can be understood as initialized at compile time, without any cost at runtime).
You can also follow the offical documentation form scikit:
Merging several answers from above into an easy to use function
function GetScriptIfNotLoaded(scriptLocationAndName)
{
var len = $('script[src*="' + scriptLocationAndName +'"]').length;
//script already loaded!
if (len > 0)
return;
var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = scriptLocationAndName;
head.appendChild(script);
}
Not sure if helpful, but I leave my solution here:
class Solution:
# @param A : string
# @param B : string
# @return a strings
def addBinary(self, A, B):
num1 = bin(int(A, 2))
num2 = bin(int(B, 2))
bin_str = bin(int(num1, 2)+int(num2, 2))
b_index = bin_str.index('b')
return bin_str[b_index+1:]
s = Solution()
print(s.addBinary("11", "100"))
git show <commit_sha>
This will show you just what's in that commit. I think you can do a range it by just putting a space between two commit shas.
git show <beginning_sha> <ending_sha>
which is pretty helpful if you're rebasing often because your feature logs will all be in a row.
When you use angle brackets, the compiler searches for the file in the include path list. When you use double quotes, it first searches the current directory (i.e. the directory where the module being compiled is) and only then it'll search the include path list.
So, by convention, you use the angle brackets for standard includes and the double quotes for everything else. This ensures that in the (not recommended) case in which you have a local header with the same name as a standard header, the right one will be chosen in each case.
I had the same error, but it was caused by the package manager process port being already used (port 8081).
To fix, I just ran the react-native
by specifying a different port, see below.
react-native run-ios --port 8090
Appart from setting maven source url to your gradle, I would suggest to add both design and appcompat libraries. Currently the latest version is 26.1.0
maven {
url "https://maven.google.com"
}
...
compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support:design:26.1.0'
This
var verificaHorario = $("#tbIntervalos").find("#" + horaInicial);
will find you the td that needs to be blocked.
Actually this will also do:
var verificaHorario = $("#" + horaInicial);
Testing for the size() of the wrapped set will answer your question regarding the existence of the id.
$(document).ready(function() {
var num = $('div.number').text()
num = addPeriod(num);
$('div.number').text('Rp. '+num)
});
function addPeriod(nStr)
{
nStr += '';
x = nStr.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + '.' + '$2');
}
return x1 + x2;
}
I follow two simple rules that avoid the vast majority of problems:
I also follow the guidelines of:
In other words:
#include <stdio.h>
#include <string.h>
#include "btree.h"
#include "collect_hash.h"
#include "collect_arraylist.h"
#include "globals.h"
Although, being guidelines, that's a subjective thing. The rules on the other hand, I enforce rigidly, even to the point of providing 'wrapper' header files with include guards and grouped includes if some obnoxious third-party developer doesn't subscribe to my vision :-)
This is a way to do it where the syntax is simpler for me to understand:
yourfilenames=`ls ./*.txt`
for eachfile in $yourfilenames
do
echo $eachfile
done
./
is the current working directory but could be replaced with any path
*.txt
returns anything.txt
You can check what will be listed easily by typing the ls
command straight into the terminal.
Basically, you create a variable yourfilenames
containing everything the list command returns as a separate element, and then you loop through it. The loop creates a temporary variable eachfile
that contains a single element of the variable it's looping through, in this case a filename. This isn't necessarily better than the other answers, but I find it intuitive because I'm already familiar with the ls
command and the for loop syntax.
First you need to get the current date
var currentDate = new Date();
Then you need to place it in the arguments of datepicker like given below
$("#datepicker").datepicker("setDate", currentDate);
Check the following jsfiddle.
That response is a Map, with a single element with key '212315952136472'. There's no 'data' key in the Map. If you want to loop through all entries, use something like this:
JSONObject userJson = JSON.parse(jsonResponse)
userJson.each { id, data -> println data.link }
If you know it's a single-element Map then you can directly access the link
:
def data = userJson.values().iterator().next()
String link = data.link
And if you knew the id (e.g. if you used it to make the request) then you can access the value more concisely:
String id = '212315952136472'
...
String link = userJson[id].link
I have cooked up a plugin for IntelliJ that – in a way – gives you var
in Java. It's a hack, so the usual disclaimers apply, but if you use IntelliJ for your Java development and want to try it out, it's at https://bitbucket.org/balpha/varsity.
You can use an IF to test:
check:
@[ "${var}" ] || ( echo ">> var is not set"; exit 1 )
Result:
$ make check
>> var is not set
Makefile:2: recipe for target 'check' failed
make: *** [check] Error 1
I'd print out the result of an2.getNodeName()
as well for debugging purposes. My guess is that your tree crawling code isn't crawling to the nodes that you think it is. That suspicion is enhanced by the lack of checking for node names in your code.
Other than that, the javadoc for Node defines "getNodeValue()" to return null for Nodes of type Element. Therefore, you really should be using getTextContent(). I'm not sure why that wouldn't give you the text that you want.
Perhaps iterate the children of your tag node and see what types are there?
Tried this code and it works for me:
String xml = "<add job=\"351\">\n" +
" <tag>foobar</tag>\n" +
" <tag>foobar2</tag>\n" +
"</add>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());
Document doc = db.parse(bis);
Node n = doc.getFirstChild();
NodeList nl = n.getChildNodes();
Node an,an2;
for (int i=0; i < nl.getLength(); i++) {
an = nl.item(i);
if(an.getNodeType()==Node.ELEMENT_NODE) {
NodeList nl2 = an.getChildNodes();
for(int i2=0; i2<nl2.getLength(); i2++) {
an2 = nl2.item(i2);
// DEBUG PRINTS
System.out.println(an2.getNodeName() + ": type (" + an2.getNodeType() + "):");
if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getTextContent());
if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getNodeValue());
System.out.println(an2.getTextContent());
System.out.println(an2.getNodeValue());
}
}
}
Output was:
#text: type (3): foobar foobar
#text: type (3): foobar2 foobar2
As you can see, the import command did work but is showing errors because it tried to locate the resources in vendor.css and couldn't find them
You should also upload your project structure and ensure that there aren't any path issues. Also, you could include the css file in the index.html or the Component template and webpack loader would extract it when built
1) you are calling it wrong way try:
$(input[name="searchBar"]).val('hi')
2) if it doesn't work call your .js file at the end of the page or trigger your function on document.ready event
$(document).ready(function() {
$(input[name="searchBar"]).val('hi');
});
If you have run php artisan config:cache
on your server, then your Laravel app could cache outdated config settings that you've put in the .env
file.
Run php artisan config:clear
to fix that.
That isn't part of the purview of CSS. colspan
describes the structure of the page's content, or gives some meaning to the data in the table, which is HTML's job.
One shouldn't use set_yticklabels
to change the fontsize, since this will also set the labels (i.e. it will replace any automatic formatter by a FixedFormatter
), which is usually undesired. The easiest is to set the respective tick_params
:
ax.tick_params(axis="x", labelsize=8)
ax.tick_params(axis="y", labelsize=20)
or
ax.tick_params(labelsize=8)
in case both axes shall have the same size.
Of course using the rcParams as in @tmdavison's answer is possible as well.
In Python 3.x, you can use the end
argument to the print()
function to prevent a newline character from being printed:
print("Nope, that is not a two. That is a", end="")
In Python 2.x, you can use a trailing comma:
print "this should be",
print "on the same line"
You don't need this to simply print a variable, though:
print "Nope, that is not a two. That is a", x
Note that the trailing comma still results in a space being printed at the end of the line, i.e. it's equivalent to using end=" "
in Python 3. To suppress the space character as well, you can either use
from __future__ import print_function
to get access to the Python 3 print function or use sys.stdout.write()
.
My two cents.. From KM.'s answer, if you want to drop one variable, you can do a countdown on @RowsToProcess instead of counting up.
DECLARE @RowsToProcess int;
DECLARE @table1 TABLE (RowID int not null primary key identity(1,1), col1 int )
INSERT into @table1 (col1) SELECT col1 FROM table2
SET @RowsToProcess = @@ROWCOUNT
WHILE @RowsToProcess > 0 -- Countdown
BEGIN
SELECT *
FROM @table1
WHERE RowID=@RowsToProcess
--do your thing here--
SET @RowsToProcess = @RowsToProcess - 1; -- Countdown
END
Don't overwrite the built-in Vim.
Instead, install it from source in a different location or via Homebrew or MacPorts in their default location then add this line to your .bashrc or .profile:
alias vim='/path/to/your/own/vim'
and/or change your $PATH
so that it looks into its location before the default location.
The best thing to do, in my opinion, is to simply download the latest MacVim which comes with a very complete vim executable and use it in Terminal.app like so.
alias vim='/Applications/MacVim.app/Contents/MacOS/Vim' # or something like that, YMMV
A simple speed hack: when you define the variable "primes," set the step to 2 to skip all even numbers automatically, and set the starting point to 1.
Then you can further optimize by instead of for i in primes, use for i in primes[:round(len(primes) ** 0.5)]. That will dramatically increase performance. In addition, you can eliminate numbers ending with 5 to further increase speed.

movie.setStopDate(movie.getStartDate() + movie.getDurationInMinutes()* 60000);

You can use String.Format:
DateTime d = DateTime.Now;
string str = String.Format("{0:00}/{1:00}/{2:0000} {3:00}:{4:00}:{5:00}.{6:000}", d.Month, d.Day, d.Year, d.Hour, d.Minute, d.Second, d.Millisecond);
// I got this result: "02/23/2015 16:42:38.234"
The difference between an operating system and a kernel:
The kernel is a part of an operating system. The operating system is the software package that communicates directly to the hardware and our application. The kernel is the lowest level of the operating system. The kernel is the main part of the operating system and is responsible for translating the command into something that can be understood by the computer. The main functions of the kernel are:
I know this is an old topic, but I managed to do it in this simple way:
select count(*) from `tablename`
where date(`datecolumn`) = '2021-02-17';

you can use enumerate keeping the ind/index of the elements is in vm, if you make vm
a set you will also have 0(1)
lookups:
vm = {-1, -1, -1, -1}
print([ind if q in vm else 9999 for ind,ele in enumerate(vm) ])
If you want to further automate this, because you are checking your module into version control, and don't want to rely upon devs remembering to npm link, you can add this to your package.json "scripts" section:
"scripts": {
"postinstall": "npm link ../somelocallib",
"postupdate": "npm link ../somelocallib"
}
This feels beyond hacky, but it seems to "work". Got the tip from this npm issue: https://github.com/npm/npm/issues/1558#issuecomment-12444454
get sock opt may be somewhat useful, however, another way would to have a signal handler installed for SIGPIPE. Basically whenever you the socket connection breaks, the kernel will send a SIGPIPE signal to the process and then you can do the needful. But this still does not provide the solution for knowing the status of the connection. hope this helps.

I am not sure but you can try intialising handler to null in onDestroy()
I think you need to do is to transform your data from object not to JSON string, but to url params.
By default, the $http service will transform the outgoing request by serializing the data as JSON and then posting it with the content- type, "application/json". When we want to post the value as a FORM post, we need to change the serialization algorithm and post the data with the content-type, "application/x-www-form-urlencoded".
Example from here.
$http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
transformRequest: function(obj) {
var str = [];
for(var p in obj)
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
return str.join("&");
},
data: {username: $scope.userName, password: $scope.password}
}).then(function () {});
To use new services added with AngularJS V1.4, see
Same problem happened to me. So if the service returns the response as a JSON string you have to deserialize the string first, then you will be able to deserialize the object type from it properly:
string json= string.Empty;
using (var streamReader = new StreamReader(response.GetResponseStream(), true))
{
json= new JavaScriptSerializer().Deserialize<string>(streamReader.ReadToEnd());
}
//To deserialize to your object type...
MyType myType;
using (var memoryStream = new MemoryStream())
{
byte[] jsonBytes = Encoding.UTF8.GetBytes(@json);
memoryStream.Write(jsonBytes, 0, jsonBytes.Length);
memoryStream.Seek(0, SeekOrigin.Begin);
using (var jsonReader = JsonReaderWriterFactory.CreateJsonReader(memoryStream, Encoding.UTF8, XmlDictionaryReaderQuotas.Max, null))
{
var serializer = new DataContractJsonSerializer(typeof(MyType));
myType = (MyType)serializer.ReadObject(jsonReader);
}
}
4 Sure it will work.... ;)
I needed an array to became a String rappresentation of an array I mean I needed that
var a = ['a','b','c'];
//became a "real" array string-like to pass on query params so was easy to do:
JSON.stringify(a); //-->"['a','b','c']"
maybe someone need it :)
my_list = ['foo', 'fob', 'faz', 'funk']
string = 'bar'
my_new_list = [x + string for x in my_list]
print my_new_list
This will print:
['foobar', 'fobbar', 'fazbar', 'funkbar']
The SQL is somewhat like the syntax of MS SQL.
SELECT * FROM [table$] WHERE *;
It is important that the table name is ended with a $ sign and the whole thing is put into brackets. As conditions you can use any value, but so far Excel didn't allow me to use what I call "SQL Apostrophes" (´), so a column title in one word is recommended.
If you have users listed in a table called "Users", and the id is in a column titled "id" and the name in a column titled "Name", your query will look like this:
SELECT Name FROM [Users$] WHERE id = 1;
Hope this helps.
youredittext.requestFocus()
call it from activity

Raymond Chen has a really good rant against using flow control macros. His best example is straight from the original Bourne shell source code:
ADDRESS alloc(nbytes)
POS nbytes;
{
REG POS rbytes = round(nbytes+BYTESPERWORD,BYTESPERWORD);
LOOP INT c=0;
REG BLKPTR p = blokp;
REG BLKPTR q;
REP IF !busy(p)
THEN WHILE !busy(q = p->word) DO p->word = q->word OD
IF ADR(q)-ADR(p) >= rbytes
THEN blokp = BLK(ADR(p)+rbytes);
IF q > blokp
THEN blokp->word = p->word;
FI
p->word=BLK(Rcheat(blokp)|BUSY);
return(ADR(p+1));
FI
FI
q = p; p = BLK(Rcheat(p->word)&~BUSY);
PER p>q ORF (c++)==0 DONE
addblok(rbytes);

}
1) To answer your question:
String s="Java";
System.out.println(s.length());
It worked fine with me,
$this->db->where("your_id !=",$your_id);
Or try this one,
$this->db->where("your_id <>",$your_id);
Or try this one,
$this->db->where("your_id IS NOT NULL");
all will work.
Technically, the proper solution is (I believe):
typeof x === "undefined"
You can sometimes get lazy and use
x == null
but that allows both an undefined variable x, and a variable x containing null, to return true.
The most important difference is this:
In case of persist
method, if the entity that is to be managed in the persistence context, already exists in persistence context, the new one is ignored. (NOTHING happened)
But in case of merge
method, the entity that is already managed in persistence context will be replaced by the new entity (updated) and a copy of this updated entity will return back. (from now on any changes should be made on this returned entity if you want to reflect your changes in persistence context)
Ad-hoc Query -
just edit wp_user table with your phpmyadmin, and choose MD5 on Function field then input your new password, save it (go button).
You have to set height as a string value when you use pixels.
document.getElementById('chartdiv').style.height = "200px"
Also try adding a DOCTYPE to your HTML for Internet Explorer.
<!DOCTYPE html>
<html> ...
The correct syntax is:
import sampleModule = require('modulename');
or
import * as sampleModule from 'modulename';
Then compile your TypeScript with --module commonjs
.
If the package doesn't come with an index.d.ts
file and its package.json
doesn't have a "typings"
property, tsc
will bark that it doesn't know what 'modulename'
refers to. For this purpose you need to find a .d.ts
file for it on http://definitelytyped.org/, or write one yourself.
If you are writing code for Node.js you will also want the node.d.ts
file from http://definitelytyped.org/.
You could try removing any alphanumeric characters and space. And then use -n
will give you the line number. Try following:
grep -vn "^[a-zA-Z0-9 ]*$" application.log
Try this with pygame:
import pygame
pygame.init() // eliminate error, pygame.error: video system not initialized
keys = pygame.key.get_pressed()
if keys[pygame.K_SPACE]:
d = "space key"
print "You pressed the", d, "."
add your script tag on the bottom of the body tag. so that script loads after html content then you won't get such error and add=
Some interesting alternatives:
OPTION 1
PrintStream p = System.out;
p.println("hello");
OPTION 2
PrintWriter p = new PrintWriter(System.out, true);
p.println("Hello");
Yes... I am using Hue 3.7.0 - The Hadoop UI and to get current date/time information we can use below commands in Hive:
SELECT from_unixtime(unix_timestamp()); --/Selecting Current Time stamp/
SELECT CURRENT_DATE; --/Selecting Current Date/
SELECT CURRENT_TIMESTAMP; --/Selecting Current Time stamp/
However, in Impala you will find that only below command is working to get date/time details:
SELECT from_unixtime(unix_timestamp()); --/Selecting Current Timestamp /
Hope it resolves your query :)
This code will dynamically generate the expression for you with the nested clauses. I have a scenario where the number of "OR" s was unknown, so I'm using the below. Usage:
private static void Main(string[] args)
{
var query = new PropertyString(@"<Query><Where>{{WhereClauses}}</Where></Query>");
var whereClause =
new PropertyString(@"<Eq><FieldRef Name='ID'/><Value Type='Counter'>{{NestClauseValue}}</Value></Eq>");
var andClause = new PropertyString("<Or>{{FirstExpression}}{{SecondExpression}}</Or>");
string[] values = {"1", "2", "3", "4", "5", "6"};
query["WhereClauses"] = NestEq(whereClause, andClause, values);
Console.WriteLine(query);
}
And here's the code:
private static string MakeExpression(PropertyString nestClause, string value)
{
var expr = nestClause.New();
expr["NestClauseValue"] = value;
return expr.ToString();
}
/// <summary>
/// Recursively nests the clause with the nesting expression, until nestClauseValue is empty.
/// </summary>
/// <param name="whereClause"> A property string in the following format: <Eq><FieldRef Name='Title'/><Value Type='Text'>{{NestClauseValue}}</Value></Eq>"; </param>
/// <param name="nestingExpression"> A property string in the following format: <And>{{FirstExpression}}{{SecondExpression}}</And> </param>
/// <param name="nestClauseValues">A string value which NestClauseValue will be filled in with.</param>
public static string NestEq(PropertyString whereClause, PropertyString nestingExpression, string[] nestClauseValues, int pos=0)
{
if (pos > nestClauseValues.Length)
{
return "";
}
if (nestClauseValues.Length == 1)
{
return MakeExpression(whereClause, nestClauseValues[0]);
}
var expr = nestingExpression.New();
if (pos == nestClauseValues.Length - 2)
{
expr["FirstExpression"] = MakeExpression(whereClause, nestClauseValues[pos]);
expr["SecondExpression"] = MakeExpression(whereClause, nestClauseValues[pos + 1]);
return expr.ToString();
}
else
{
expr["FirstExpression"] = MakeExpression(whereClause, nestClauseValues[pos]);
expr["SecondExpression"] = NestEq(whereClause, nestingExpression, nestClauseValues, pos + 1);
return expr.ToString();
}
}

It really depends on your definition of special characters. I find that a whitelist rather than a blacklist is the best approach in most situations:
tmp = Regex.Replace(n, "[^0-9a-zA-Z]+", "");
You should be careful with your current approach because the following two items will be converted to the same string and will therefore be indistinguishable:
"TRA-12:123"
"TRA-121:23"
here's mine:
public static string RelativePathTo(this System.IO.DirectoryInfo @this, string to)
{
var rgFrom = @this.FullName.Split(new[] { Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar }, StringSplitOptions.RemoveEmptyEntries);
var rgTo = to.Split(new[] { Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar }, StringSplitOptions.RemoveEmptyEntries);
var cSame = rgFrom.TakeWhile((p, i) => i < rgTo.Length && string.Equals(p, rgTo[i])).Count();
return Path.Combine(
Enumerable.Range(0, rgFrom.Length - cSame)
.Select(_ => "..")
.Concat(rgTo.Skip(cSame))
.ToArray()
);
}
You could use these functions:
sp_help TableName
sp_helptext ProcedureName
The most basic way to iterate over a hash is as follows:
hash.each do |key, value|
puts key
puts value
end
function setMarkers(map,locations){
for (var i = 0; i < locations.length; i++)
{
var loan = locations[i][0];
var lat = locations[i][1];
var long = locations[i][2];
var add = locations[i][3];
latlngset = new google.maps.LatLng(lat, long);
var marker = new google.maps.Marker({
map: map, title: loan , position: latlngset
});
map.setCenter(marker.getPosition());
marker.content = "<h3>Loan Number: " + loan + '</h3>' + "Address: " + add;
google.maps.events.addListener(marker,'click', function(map,marker){
map.infowindow.setContent(marker.content);
map.infowindow.open(map,marker);
});
}
}
Then move var infowindow = new google.maps.InfoWindow()
to the initialize()
function:
function initialize() {
var myOptions = {
center: new google.maps.LatLng(33.890542, 151.274856),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("default"),
myOptions);
map.infowindow = new google.maps.InfoWindow();
setMarkers(map,locations)
}
Here is a totally out of the box solution.
In the ahk script, a) Ftp the commands (.ksh) file to the linux machine
b) Use plink like below. Plink should be installed if you have putty.
plink sessionname -l username -pw password test.ksh
or
plink -ssh example.com -l username -pw password test.ksh
All the steps will be performed in sequence whenever you press F9 in windows.

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local
.
Another simple way is to use @reboot
in your crontab. Read the cron manpage for details.
However, if you want to do things properly, in addition to adding a script to /etc/init.d
you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d
which creates a symlink from some of the /etc/rc*
directories to your script. So, you'd need to do something like:
update-rc.d yourscriptname start 2
However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README
has some details and further pointers.

You could use KBKeyboardObserver library. It contains some examples and provides simple interface.
A basic implementation which you'll need to adapt would look something like this:
function insertParam(key, value) {
key = encodeURIComponent(key);
value = encodeURIComponent(value);
// kvp looks like ['key1=value1', 'key2=value2', ...]
var kvp = document.location.search.substr(1).split('&');
let i=0;
for(; i<kvp.length; i++){
if (kvp[i].startsWith(key + '=')) {
let pair = kvp[i].split('=');
pair[1] = value;
kvp[i] = pair.join('=');
break;
}
}
if(i >= kvp.length){
kvp[kvp.length] = [key,value].join('=');
}
// can return this or...
let params = kvp.join('&');
// reload page with new params
document.location.search = params;
}
This is approximately twice as fast as a regex or search based solution, but that depends completely on the length of the querystring and the index of any match
the slow regex method I benchmarked against for completions sake (approx +150% slower)
function insertParam2(key,value)
{
key = encodeURIComponent(key); value = encodeURIComponent(value);
var s = document.location.search;
var kvp = key+"="+value;
var r = new RegExp("(&|\\?)"+key+"=[^\&]*");
s = s.replace(r,"$1"+kvp);
if(!RegExp.$1) {s += (s.length>0 ? '&' : '?') + kvp;};
//again, do what you will here
document.location.search = s;
}

throw new Error("Not supported.")
}
const peerConnection = new RTCPeerConnection({ iceServers: [] })
peerConnection.createDataChannel('')
peerConnection.createOffer(peerConnection.setLocalDescription.bind(peerConnection), () => { })
peerConnection.addEventListener("icecandidateerror", (event) => {
throw new Error(event.errorText)
})
return new Promise(async resolve => {

if (candidate && candidate.candidate) {
const result = candidate.candidate.split(" ")[4]

This is an example of a good one and also an example of why you would never want to write one. It is a Fowler / Noll / Vo (FNV) Hash which is equal parts computer science genius and pure voodoo:
unsigned fnv_hash_1a_32 ( void *key, int len ) {
unsigned char *p = key;
unsigned h = 0x811c9dc5;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x01000193;
return h;
}
unsigned long long fnv_hash_1a_64 ( void *key, int len ) {
unsigned char *p = key;
unsigned long long h = 0xcbf29ce484222325ULL;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x100000001b3ULL;
return h;
}
Edit:
I have used this one successfully
System.IO.Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName)
It works even inside linqpad.
If you want to check contents are equal or not then just use JSON.stringify(obj)
Eg - var a ={key:val};
var b ={key:val};
JSON.stringify(a) == JSON.stringify(b) -----> If contents are same you gets true.
Note that this is the procedural approach, which I use for quick debugging
DB::enableQueryLog();
// Run your queries
// ...
// Then to retrieve everything since you enabled the logging:
$queries = DB::getQueryLog();
foreach($queries as $i=>$query)
{
Log::debug("Query $i: " . json_encode($query));
}
in your header, use:
use DB;
use Illuminate\Support\Facades\Log;
The output will look something like this (default log file is laravel.log):
[2015-09-25 12:33:29] testing.DEBUG: Query 0: {"query":"select * from 'users' where ('user_id' = ?)","bindings":["9"],"time":0.23}
***I know this question specified Laravel 3/4 but this page comes up when searching for a general answer. Newbies to Laravel may not know there is a difference between versions. Since I never see DD::enableQueryLog()
mentioned in any of the answers I normally find, it may be specific to Laravel 5 - perhaps someone can comment on that.
In front-end JavaScript/HTML, you can load a binary file as an image, you do not have to convert to base64:

I hit the same shared memory realm does not exist
symptom (on Windows) but for a different reason. I had just installed Oracle (XE) and after some troubleshooting, established that my installation was corrupt due to the presence of an ORACLE_HOME environment property at the time I installed it.
If this is TLDR, skip to 'So to resolve:'!
My initial symptom was:
Message 850 not found; No message file for product=NETWORK, facility=NL
Apparently the Windows install reads the ORACLE_HOME from the registry and doesn't need (and certainly in my case shouldn't have...) an environment property.
Remove it, as follows:
Following the restart I was then able to get error messages other than 'No message file...' and could start looking at what the issue was. Setting the ORACLE_SID to XE and connecting @XE I got as far as the errors in this page, namely the following symptoms:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Another symptom was: When launching the 'Get started' page it failed to connect, giving a not found error (if I recall correctly), despite the Windows listener & XE services being started. As noted in another answer, this could be due to the windows services not being started. In my case those services were started, so something else was misconfigured.
At this point, I figured maybe my install had just gone so badly wrong due to the presence of my bad ORACLE_HOME environment property that I should reinstall. (Previous reinstalls hadn't helped, but those had all been before I noticed the ORACLE_HOME system environment property (probably set up by me a year ago!).
So to resolve:
I am using flutter and installed virtual device using the terminal
flutter emulator --launch {avd_name} -v
will print a more detailed output, making it easier for debugging the specific errors
Enabling the virtualization options in BIOS worked in my particular case (VDT)
The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.
You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \r
rather than the linux standard \n
or better still the suspenders and belt approach of windows with \r\n
.
pandas.read_csv(filename, sep='\t', lineterminator='\r')
You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.

doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set
df = pandas.read_csv(doc, sep='\t')

I know I'm a bit late in this thread. However, here is my answer, valid since Java 7 and up.
The following snippet
if(Files.isRegularFile(Paths.get(pathToFile))) {
// do something
}
is perfectly satifactory, because method isRegularFile
returns false
if file does not exist. Therefore, no need to check if Files.exists(...)
.
Note that other parameters are options indicating how links should be handled. By default, symbolic links are followed.
The simplest way I think is 'Ctrl+P' > save as 'pdf'. That's it.

Yes, your conclusion is correct. socket.recv
is a blocking call.
socket.recv(1024)
will read at most 1024 bytes, blocking if no data is waiting to be read. If you don't read all data, an other call to socket.recv
won't block.
socket.recv
will also end with an empty string if the connection is closed or there is an error.
If you want a non-blocking socket, you can use the select module (a bit more complicated than just using sockets) or you can use socket.setblocking
.
I had issues with socket.setblocking
in the past, but feel free to try it if you want.
Well I did a bit of searching around the internet for you and I found this handy link.
Easiest way to find duplicate values in a JavaScript array
You can adapt the sample code that is provided in the above link, courtesy of "swilliams" to your solution.
Do you mean that the date range of the selected rows should not lie fully within the specified date range? In which case:
select *
from test_table
where start_date < date '2009-12-15'
or end_date > date '2010-01-02';
(Syntax above is for Oracle, yours may differ slightly).
I found that in Ruby, you can pass two arguments to send_keys
Like this:
element.send_keys(:control, 'A')
How about?
DF$Den<-ifelse (is.na(DF$Denial1) | is.na(DF$Denial2) | is.na(DF$Denial3), "0", "1")
The FOR-LOOP generally works, but there are some issues. The FOR doesn't accept empty lines and lines with more than ~8190 are problematic. The expansion works only reliable, if the delayed expansion is disabled.
Detection of CR/LF versus single LF seems also a little bit complicated.
Also NUL characters are problematic, as a FOR-Loop immediatly cancels the reading.
Direct binary reading seems therefore nearly impossible.
The problem with empty lines can be solved with a trick. Prefix each line with a line number, using the findstr command, and after reading, remove the prefix.
@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ t.txt"`) do (
set "var=%%a"
SETLOCAL EnableDelayedExpansion
set "var=!var:*:=!"
echo(!var!
ENDLOCAL
)
Toggling between enable and disabled delayed expansion is neccessary for the safe working with strings, like !
or ^^^xy!z
.
That's because the line set "var=%%a"
is only safe with DisabledDelayedExpansion, else exclamation marks are removed and the carets are used as (secondary) escape characters and they are removed too.
But using the variable var
is only safe with EnabledDelayedExpansion, as even a call %%var%%
will fail with content like "&"&
.
EDIT: Added set/p variant
There is a second way of reading a file with set /p
, the only disadvantages are that it is limited to ~1024 characters per line and it removes control characters at the line end.
But the advantage is, you didn't need the delayed toggling and it's easier to store values in variables
@echo off
setlocal EnableDelayedExpansion
set "file=%~1"
for /f "delims=" %%n in ('find /c /v "" %file%') do set "len=%%n"
set "len=!len:*: =!"
<%file% (
for /l %%l in (1 1 !len!) do (
set "line="
set /p "line="
echo(!line!
)
)
For reading it "binary" into a hex-representation
You could look at SO: converting a binary file to HEX representation using batch file
Just check in you projects properties >build ->packaging WAR file compress.
The simplest (but not the fastest) way to iterate a directory tree and list relative file paths is to use FORFILES.
forfiles /s /m *.txt /c "cmd /c echo @relpath"
The relative paths will be quoted with a leading .\
as in
".\Doc1.txt"
".\subdir\Doc2.txt"
".\subdir\Doc3.txt"
To remove quotes:
for /f %%A in ('forfiles /s /m *.txt /c "cmd /c echo @relpath"') do echo %%~A
To remove quotes and the leading .\
:
setlocal disableDelayedExpansion
for /f "delims=" %%A in ('forfiles /s /m *.txt /c "cmd /c echo @relpath"') do (
set "file=%%~A"
setlocal enableDelayedExpansion
echo !file:~2!
endlocal
)
or without using delayed expansion
for /f "tokens=1* delims=\" %%A in (
'forfiles /s /m *.txt /c "cmd /c echo @relpath"'
) do for %%F in (^"%%B) do echo %%~F
What are iml files in Android Studio project?
A Google search on iml file
turns up:
IML is a module file created by IntelliJ IDEA, an IDE used to develop Java applications. It stores information about a development module, which may be a Java, Plugin, Android, or Maven component; saves the module paths, dependencies, and other settings.
(from this page)
why not to use gradle scripts to integrate with external modules that you add to your project.
You do "use gradle scripts to integrate with external modules", or your own modules.
However, Gradle is not IntelliJ IDEA's native project model — that is separate, held in .iml
files and the metadata in .idea/
directories. In Android Studio, that stuff is largely generated out of the Gradle build scripts, which is why you are sometimes prompted to "sync project with Gradle files" when you change files like build.gradle
. This is also why you don't bother putting .iml
files or .idea/
in version control, as their contents will be regenerated.
If I have a team that work in different IDE's like Eclipse and AS how to make project IDE agnostic?
To a large extent, you can't.
You are welcome to have an Android project that uses the Eclipse-style directory structure (e.g., resources and manifest in the project root directory). You can teach Gradle, via build.gradle
, how to find files in that structure. However, other metadata (compileSdkVersion
, dependencies, etc.) will not be nearly as easily replicated.
Other alternatives include:
Move everybody over to another build system, like Maven, that is equally integrated (or not, depending upon your perspective) to both Eclipse and Android Studio
Hope that Andmore takes off soon, so that perhaps you can have an Eclipse IDE that can build Android projects from Gradle build scripts
Have everyone use one IDE
If a
is your array:
In [11]: a[:,:2]

if you don't or cannot go through cursor and if you have only paths or File objects, you can use since API level 8 (2.2) public static Bitmap createVideoThumbnail (String filePath, int kind)
The following code runs perfectly:
Bitmap bMap = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MICRO_KIND);
Replacing forward(/) slash with backward(\) slash will do the job. The folder separator in Windows is \ not /
It doesn't work because it's not supported
The
DEFAULT
clause specifies a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression. This means, for example, that you cannot set the default for a date column to be the value of a function such asNOW()
orCURRENT_DATE
. The exception is that you can specifyCURRENT_TIMESTAMP
as the default for aTIMESTAMP
column
By default, Jenkins stores all of its data in this directory on the file system.
There are a few ways to change the Jenkins home directory:
JENKINS_HOME
variable in your Jenkins configuration file (e.g. /etc/sysconfig/jenkins
on Red Hat Linux).JENKINS_HOME
environment variable.JENKINS_HOME
before launching your web container, or before launching Jenkins directly from the WAR file.JENKINS_HOME
Java system property when launching your web container, or when launching Jenkins directly from the WAR file.web.xml
in jenkins.war (or its expanded image in your web container). This is not recommended.
This value cannot be changed while Jenkins is running.
It is shown here to help you ensure that your configuration is taking effect.In my case I finally made it with
import java.lang.Thread;
import java.io.BufferedReader;
import java.io.InputStreamReader;
final BufferedReader in = new BufferedReader(new InputStreamReader(
Thread.currentThread().getContextClassLoader().getResourceAsStream("file.txt"))
); // no initial slash in file.txt
I'm not entirely sold on the use of IDEs. However, I think that the most valuable aspect of a good IDE, like Eclipse, is the well-integrated Cscope-style functionality rapid comprehension of a large code base.
For example, in Eclipse, you see a method takes an argument of type FooBar, yet you have no idea what it means. Rather than waste a minute finding the definition the hard way (and risk all sorts of distractions along the way), just select FooBar, hit F3, and it opens the relevant source file to the very line that FooBar is defined.
The downside of IDEs, in my opinion, is that they give you a bigger learning curve, except in the case in which you want to use the absolutely default configuration. (This is true for Emacs as well.)
With C# 6.0, you can create a dictionary in following way:
var dict = new Dictionary<string, int>
{
["one"] = 1,
["two"] = 2,
["three"] = 3
};
It even works with custom types.
Please make sur that res.getInt(1) is not null. If it can be null, use Integer count = null; and not int count =0;
Integer count = null;
if (rs! = null) (
while (rs.next ()) (
count = rs.getInt (1);
)
)
Go to Window → Preferences → Java → Installed JREs. Select the JRE you're using, click Edit, and there will be a line for Default VM Arguments which will apply to every execution. For instance, I use this on OS X to hide the icon from the dock, increase max memory and turn on assertions:
-Xmx512m -ea -Djava.awt.headless=true
You can also pass date format
df.withColumn("Date",to_date(unix_timestamp(df.col("your_date_column"), "your_date_format").cast("timestamp")))
For Example
import org.apache.spark.sql.functions._
val df = sc.parallelize(Seq("06 Jul 2018")).toDF("dateCol")
df.withColumn("Date",to_date(unix_timestamp(df.col("dateCol"), "dd MMM yyyy").cast("timestamp")))
I am using searchform.php
and search.php
files as already mentioned, but here I provide the actual code.
Creating a Search Page codex
page helps here and #Creating_a_Search_Page_Template
shows the search query.
In my case I pass the $search_query
arguments to the WP_Query Class
(which can determine if is search query!). I then run The Loop to display the post information I want to, which in my case is the the_permalink and the_title
.
Search box form:
<form class="search" method="get" action="<?php echo home_url(); ?>" role="search">
<input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search …', 'placeholder' ) ?>" value="<?php echo get_search_query() ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label' ) ?>" />
<button type="submit" role="button" class="btn btn-default right"/><span class="glyphicon glyphicon-search white"></span></button>
</form>
search.php
template file:
<?php
global $query_string;
$query_args = explode("&", $query_string);
$search_query = array();
foreach($query_args as $key => $string) {
$query_split = explode("=", $string);
$search_query[$query_split[0]] = urldecode($query_split[1]);
} // foreach
$the_query = new WP_Query($search_query);
if ( $the_query->have_posts() ) :
?>
<!-- the loop -->
<ul>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
</li>
<?php endwhile; ?>
</ul>
<!-- end of the loop -->
<?php wp_reset_postdata(); ?>
<?php else : ?>
<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>
There are a number of different options, based on what exactly the effect you're going for is. Chris Coyier did a piece on just this way back when. Worth a read:
I just want to add that if the constructor is called from a different file, then something as simple as forgetting to export the constructor with
module.exports = NAME_OF_CONSTRUCTOR
will also cause the "Not a constructor" exception.
It should be MM
for months. You are asking for minutes.
DateTime.Now.ToString("dd/MM/yyyy");

We have had the same issue in eclipse or intellij. After trying many alternative solutions, I found simple solution - add this config to your application.properties:
spring.main.web-application-type=none
An NDF file is a user defined secondary database file of Microsoft SQL Server with an extension .ndf, which store user data. Moreover, when the size of the database file growing automatically from its specified size, you can use .ndf file for extra storage and the .ndf file could be stored on a separate disk drive. Every NDF file uses the same filename as its corresponding MDF file. We cannot open an .ndf file in SQL Server Without attaching its associated .mdf file.
I have been using this for years and it works well. Could probably be made more efficient, but
grabstring("Test string","","",0) returns Test string
grabstring("Test string","Test ","",0) returns string
grabstring("Test string","s","",5) returns string
function grabstring($strSource,$strPre,$strPost,$StartAt) {
if(@strpos($strSource,$strPre)===FALSE && $strPre!=""){
return("");
}
@$Startpoint=strpos($strSource,$strPre,$StartAt)+strlen($strPre);
if($strPost == "") {
$EndPoint = strlen($strSource);
} else {
if(strpos($strSource,$strPost,$Startpoint)===FALSE){
$EndPoint= strlen($strSource);
} else {
$EndPoint = strpos($strSource,$strPost,$Startpoint);
}
}
if($strPre == "") {
$Startpoint = 0;
}
if($EndPoint - $Startpoint < 1) {
return "";
} else {
return substr($strSource, $Startpoint, $EndPoint - $Startpoint);
}
}
This will work if you are not blocking.
If you are planing on doing sleeps, its absolutely imperative that you use the event to do the sleep. If you leverage the event to sleep, if someone tells you to stop while "sleeping" it will wake up. If you use time.sleep()
your thread will only stop after it wakes up.
import threading
import time
duration = 2
def main():
t1_stop = threading.Event()
t1 = threading.Thread(target=thread1, args=(1, t1_stop))
t2_stop = threading.Event()
t2 = threading.Thread(target=thread2, args=(2, t2_stop))
time.sleep(duration)
# stops thread t2
t2_stop.set()
def thread1(arg1, stop_event):
while not stop_event.is_set():
stop_event.wait(timeout=5)
def thread2(arg1, stop_event):
while not stop_event.is_set():
stop_event.wait(timeout=5)
I found the solution. The answer is very simple. write the below code in your constructor.
import { Component, OnInit, OnDestroy, Input } from "@angular/core";
// Import this, and write at the top of your .ts file
import { HostListener } from "@angular/core";
@Component({
selector: "app-login",
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit, OnDestroy {
// Declare height and width variables
scrHeight:any;
scrWidth:any;
@HostListener('window:resize', ['$event'])
getScreenSize(event?) {
this.scrHeight = window.innerHeight;
this.scrWidth = window.innerWidth;
console.log(this.scrHeight, this.scrWidth);
}
// Constructor
constructor() {
this.getScreenSize();
}
}
====== Working Code (Another) ======
export class Dashboard {
mobHeight: any;
mobWidth: any;
constructor(private router:Router, private http: Http){
this.mobHeight = (window.screen.height) + "px";
this.mobWidth = (window.screen.width) + "px";
console.log(this.mobHeight);
console.log(this.mobWidth)
}
}
Optionally you can use database function for date/time formatting. For example in MySQL query use:
SELECT DATE_FORMAT(DATETIMEAPP,'%d-%m-%Y') AS date, DATE_FORMT(DATETIMEAPP,'%H:%i:%s') AS time FROM yourtable
I think that over databases provides solutions for date formatting too
I have made a variant solution based on paxdiablo's post
Place the following code in Waitlink.cmd
@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
:loop
set state=up
ping -n 1 !ipaddr! >nul: 2>nul:
if not !errorlevel!==0 set state=down
echo.Link is !state!
if "!state!"=="up" (
goto :endloop
)
ping -n 6 127.0.0.1 >nul: 2>nul:
goto :loop
:endloop
endlocal
For example use it from another batch file like this
call Waitlink someurl.com
net use o: \\someurl.com\myshare
The call to waitlink will only return when a ping was succesful. Thanks to paxdiablo and Gabe. Hope this helps someone else.
I think the simplest way is trying to change the system date (that requires admin rights):
date %date%
if errorlevel 1 (
echo You have NOT admin rights
) else (
echo You have admin rights
)
If %date%
variable may include the day of week, just get the date from last part of DATE
command:
for /F "delims=" %%a in ('date ^<NUL') do set "today=%%a" & goto break
:break
for %%a in (%today%) do set "today=%%a"
date %today%
if errorlevel 1 ...
This also happens when you use development docker compose like the below, in production. You don't want to be building images in production as that breaks the ideology of containers. We should be deploying images:
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
Change that to use the built image:
web:
command: /bin/bash run.sh
image: registry.voxcloud.co.za:9000/dyndns_api_web:0.1
ports:
- "8000:8000"
And as suggested above by Siu Ching Pong -Asuka Kenji with the function which in my opinion makes more sense and leaves you with the convenience of the map type without the function wrapper around:
// romanNumeralDict returns map[int]string dictionary, since the return
// value is always the same it gives the pseudo-constant output, which
// can be referred to in the same map-alike fashion.
var romanNumeralDict = func() map[int]string { return map[int]string {
1000: "M",
900: "CM",
500: "D",
400: "CD",
100: "C",
90: "XC",
50: "L",
40: "XL",
10: "X",
9: "IX",
5: "V",
4: "IV",
1: "I",
}
}
func printRoman(key int) {
fmt.Println(romanNumeralDict()[key])
}
func printKeyN(key, n int) {
fmt.Println(strings.Repeat(romanNumeralDict()[key], n))
}
func main() {
printRoman(1000)
printRoman(50)
printKeyN(10, 3)
}
If you have a view with multiple constrains, a much easier way without having to create multiple outlets would be:
In interface builder, give each constraint you wish to modify an identifier:
Then in code you can modify multiple constraints like so:
for constraint in self.view.constraints {
if constraint.identifier == "myConstraint" {
constraint.constant = 50
}
}
myView.layoutIfNeeded()
You can give multiple constrains the same identifier thus allowing you to group together constrains and modify all at once.
Using only virtualenv (without virtualenvwrapper), setting environment variables is easy through the activate
script you sourcing in order to activate the virtualenv.
Run:
nano YOUR_ENV/bin/activate
Add the environment variables to the end of the file like this:
export KEY=VALUE
You can also set a similar hook to unset the environment variable as suggested by Danilo Bargen in his great answer above if you need.
Base64 is a way to represent bytes in a textual form (as a string). So there is no such thing as a Base64 encoded byte[]. You'd have a base64 encoded string, which you could decode back to a byte[]
.
However, if you want to end up with a byte array, you could take the base64 encoded string and convert it to a byte array, like:
string base64String = Convert.ToBase64String(bytes);
byte[] stringBytes = Encoding.ASCII.GetBytes(base64String);
This, however, makes no sense because the best way to represent a byte[] as a byte[], is the byte[] itself :)
SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 28800
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 28800
At first, wait_timeout = 28800 which is the default value. To change the session value, you need to set the global variable because the session variable is read-only.
SET @@GLOBAL.wait_timeout=300
After you set the global variable, the session variable automatically grabs the value.
SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 300
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 300
Next time when the server restarts, the session variables will be set to the default value i.e. 28800.
P.S. I m using MySQL 5.6.16
This answer has a code example, which implements the algorithm described in the paper Practical In-Place Merging by Bing-Chao Huang and Michael A. Langston. I have to admit that I do not understand the details, but the given complexity of the merge step is O(n).
From a practical perspective, there is evidence that pure in-place implementations are not performing better in real world scenarios. For example, the C++ standard defines std::inplace_merge, which is as the name implies an in-place merge operation.
Assuming that C++ libraries are typically very well optimized, it is interesting to see how it is implemented:
The implementation delegates to __inplace_merge, which dodges the problem by trying to allocate a temporary buffer:
typedef _Temporary_buffer<_BidirectionalIterator, _ValueType> _TmpBuf;
_TmpBuf __buf(__first, __len1 + __len2);
if (__buf.begin() == 0)
std::__merge_without_buffer
(__first, __middle, __last, __len1, __len2, __comp);
else
std::__merge_adaptive
(__first, __middle, __last, __len1, __len2, __buf.begin(),
_DistanceType(__buf.size()), __comp);
Otherwise, it falls back to an implementation (__merge_without_buffer), which requires no extra memory, but no longer runs in O(n) time.
Looks similar. It delegates to a function, which also tries to allocate a buffer. Depending on whether it got enough elements, it will choose the implementation. The constant-memory fallback function is called __buffered_inplace_merge.
Maybe even the fallback is still O(n) time, but the point is that they do not use the implementation if temporary memory is available.
Note that the C++ standard explicitly gives implementations the freedom to choose this approach by lowering the required complexity from O(n) to O(N log N):
Complexity: Exactly N-1 comparisons if enough additional memory is available. If the memory is insufficient, O(N log N) comparisons.
Of course, this cannot be taken as a proof that constant space in-place merges in O(n) time should never be used. On the other hand, if it would be faster, the optimized C++ libraries would probably switch to that type of implementation.
If you do not want to make your control runat server in case you need the ID or simply don't want to add it to the viewstate,
<div id="formSpinner" class="<%= _css %>">
</div>
in the back-end:
protected string _css = "modalBackground";
You can assume there are two kinds of queues associated with each lock object. One is blocked queue containing thread waiting for the monitor lock, other is waiting queue containing thread waiting to be notified. (Thread will be put into waiting queue when they call Object.wait
).
Each time the lock is available, the scheduler choose one thread from blocked queue to execute.
When notify
is called, there will only be one thread in waiting queue are put into blocked queue to contend for the lock, while notifyAll
will put all thread in waiting queue into blocked queue.
Now can you see the difference?
Although in both case there will only be one thread get executed, but with notifyAll
, other threads still get a change to be executed(Because they are in the blocked queue) even if they failed to contend the lock.
I basically recommend use notifyAll
all the time althrough there may be a little performance penalty.
And use notify
only if :
For example:
@xagyg 's answer gives a example which notify
will cause deadlock. In his example, both producer and consumer are related with the same lock object. So when a producer calls notify
, either a producer or a consumer can be notified. But if a producer is woken up it can not make the programe proceed because the buffer is already full.So a deadlock happens.
There are two ways to solve it :
notifyALl
as @xagyg suggests.Change your nginx.conf
user
property to www-static
files owener.
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/

# same other config
There are 3 steps that needs to be run.
It is very interesting that this simplest usage is not clearly described anywhere. And i believe there is a danger, you should pay attention to the verified_email
parameter coming in the response. Because if I am not wrong it may yield fake emails to register your application. (This is just my interpretation, has a fair chance that I may be wrong!)
I find facebook's OAuth mechanics much much clearly described.
Since you cannot have two methods with the same name and signature you have to use the ActionName
attribute:
[HttpGet]
public ActionResult Index()
{
// your code
return View();
}
[HttpPost]
[ActionName("Index")]
public ActionResult IndexPost()
{
// your code
return View();
}
Also see "How a Method Becomes An Action"
I was using nodemailer npm module. The below code solved the issue
tls: {
// do not fail on invalid certs
rejectUnauthorized: false
}
At the end of the day it doesn't matter because C++ compilers can deal with the files in either format. If it's a real issue within your team, flip a coin and move on to the actual work.
You need to do encode
on tmp[0]
, not on tmp
.
tmp
is not a string. It contains a (Unicode) string.
Try running type(tmp)
and print dir(tmp)
to see it for yourself.
ASP.NET MVC doesn't support custom 404 pages very well. Custom controller factory, catch-all route, base controller class with HandleUnknownAction
- argh!
IIS custom error pages are better alternative so far:
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Replace">
<remove statusCode="404" />
<error statusCode="404" responseMode="ExecuteURL" path="/Error/PageNotFound" />
</httpErrors>
</system.webServer>
public class ErrorController : Controller
{
public ActionResult PageNotFound()
{
Response.StatusCode = 404;
return View();
}
}
public static void main(String[] args) {
@SuppressWarnings("serial")
List<Object> lst = new ArrayList<Object>() {
@Override
public boolean add(Object e) {
if(!contains(e))
return super.add(e);
else
return false;
}
};
lst.add("ABC");
lst.add("ABC");
lst.add("ABCD");
lst.add("ABCD");
lst.add("ABCE");
System.out.println(lst);
}
This is the better way

This thread has some great tips. However....
@GirishB's answer isn't correct - sorry. Jartender's is best.
Also, every post in here seems to assume you're logging in to the Linux guest as root, except for @tomoguisuru. Yuck! Don't use root, use a separate user account and "sudo" when you need root privileges. Then this user (or any other user who needs the shared folder) should have membership in the vboxsf group, and @tomoguisuru's command is perfect, even terser than what I use.
Forget running mount yourself. Set up the shared folder to auto mount and you'll find the shared folder - it's under /media in my OEL (RH and Centos probably the same). If it's not there, just run "mount" with no arguments and look for the mounted directory of type vboxsf.
Expand your one liner into multiple lines. Then it becomes easy:
f.write(re.split("Tech ID:|Name:|Account #:",line)[-1])
parts = re.split("Tech ID:|Name:|Account #:",line)
wanted_part = parts[-1]
wanted_part_stripped = wanted_part.strip()
f.write(wanted_part_stripped)
on body tag's onLoad try setting it like
document.getElementById("subEmail").style.backgroundColor = "yellow";
and after that on change of that input field check if some value is there, or paint it yellow like
function checkFilled() {
var inputVal = document.getElementById("subEmail");
if (inputVal.value == "") {
inputVal.style.backgroundColor = "yellow";
}
}
PLease make sure to backup your changes before running these commmand in a separate folder
git checkout branch_name
Checkout on your branch
git merge --abort
Abort the merge
git status
Check status of the code after aborting the merge
git reset --hard origin/branch_name
these command will reset your changes and align your code with the branch_name (branch) code.
It means the class is not yet added to the repository.
If your project was checked-out (most probably a CVS project) and you added a new class file, it will have the ? icon.

Two things. First, you must base64 decode the mykey.pem
file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey
ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec
, which is based on the SubjectPublicKeyInfo
ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

haha, man, I just asked this question a few hours ago (kind of)...try this:
example:
someIntList.ForEach(i=>i+5);
ForEach()
is one of the built in .NET methods
This will modify the list, as opposed to returning a new one.
Just an alternative to
ls -d "$PWD/"*
to pinpoint that *
is shell expansion, so
echo "$PWD/"*
would do the same (the drawback you cannot use -1
to separate by new lines, not spaces).
Use Ctrl-N to get a list of word suggestions while in insert mode. Type :help i_CTRL-N
to see Vim's documentation on this functionality.
Here is an example of importing the Python dictionary into Vim.
The only way I know to deal with this is to create a new workspace, import projects from the polluted workspace, reconstructing all my settings (a major pain) and then delete the old workspace. Is there an easier way to deal with this?
For synchronizing or restoring all our settings we use Workspace Mechanic. Once all the settings are recorded its one click and all settings are restored... You can also setup a server which provides those settings for all users.
If you need to order your code into namespaces, just use the keyword namespace
:
file1.php
namespace foo\bar;
In file2.php
$obj = new \foo\bar\myObj();
You can also use use
. If in file2 you put
use foo\bar as mypath;
you need to use mypath
instead of bar
anywhere in the file:
$obj = new mypath\myObj();
Using use foo\bar;
is equal to use foo\bar as bar;
.
It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null
.
Given your statement:
img1.ImageUrl = ConfigurationManager
.AppSettings
.Get("Url")
.Replace("###", randomString)
+ Server.UrlEncode(
((System.Web.UI.MobileControls.Form)Page
.FindControl("mobileForm"))
.Title);
I'm guessing either the call to AppSettings.Get("Url")
is returning null because the value isn't found or the call to Page.FindControl("mobileForm")
is returning null because the control isn't found.
You could easily break this out into multiple statements to solve the problem:
var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
as System.Web.UI.MobileControls.Form;
if(configUrl != null && mobileFormControl != null)
{
img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}
You can get everything through ExternalContext
. In JSF 1.x, you can get the raw HttpServletResponse
object by ExternalContext#getResponse()
. In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream()
without the need to grab the HttpServletResponse
from under the JSF hoods.
On the response, you should set the Content-Type
header so that the client knows which application to associate with the provided file. And, you should set the Content-Length
header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition
header to attachment
if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.
Most important part is to call FacesContext#responseComplete()
to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException
with a message like getoutputstream() has already been called for this response
when the JSF implementation calls getWriter()
to render HTML.
You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink>
and <h:commandButton>
. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.
In case you're using e.g. PrimeFaces <p:commandXxx>
, then you need to make sure that you explicitly turn off ajax via ajax="false"
attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" />
in the command component.
public void download() throws IOException {
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.
OutputStream output = ec.getResponseOutputStream();
// Now you can write the InputStream of the file to the above OutputStream the usual way.
// ...
fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}
public void download() throws IOException {
FacesContext fc = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();
response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.
OutputStream output = response.getOutputStream();
// Now you can write the InputStream of the file to the above OutputStream the usual way.
// ...
fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}
In case you need to stream a static file from the local disk file system, substitute the code as below:
File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();
// ...
Files.copy(file.toPath(), output);
In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output
there where the API being used expects an OutputStream
.
E.g. iText PDF:
String fileName = "dynamic.pdf";
String contentType = "application/pdf";
// ...
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();
E.g. Apache POI HSSF:
String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";
// ...
HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();
Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.
If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile()
methods taking either a File
, or an InputStream
, or a byte[]
, and specifying whether the file should be downloaded as an attachment (true
) or inline (false
).
public void download() throws IOException {
Faces.sendFile(file, true);
}
Yes, this code is complete as-is. You don't need to invoke responseComplete()
and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.
If you want to use a color from colors.xml , experiment :
public View getView(int position, View convertView, ViewGroup parent) {
...
View rowView = inflater.inflate(this.rowLayoutID, parent, false);
rowView.setBackgroundColor(rowView.getResources().getColor(R.color.my_bg_color));
TextView title = (TextView) rowView.findViewById(R.id.txtRowTitle);
title.setTextColor(
rowView.getResources().getColor(R.color.my_title_color));
...
}
You can use too:
private static final int bgColor = 0xAAAAFFFF;
public View getView(int position, View convertView, ViewGroup parent) {
...
View rowView = inflater.inflate(this.rowLayoutID, parent, false);
rowView.setBackgroundColor(bgColor);
...
}
If this is only for dev machines in order to save space then just go with simple recovery mode and you’ll be doing fine.
On production machines though I’d strongly recommend that you keep the databases in full recovery mode. This will ensure you can do point in time recovery if needed.
Also – having databases in full recovery mode can help you to undo accidental updates and deletes by reading transaction log. See below or more details.
How can I rollback an UPDATE query in SQL server 2005?
Read the log file (*.LDF) in sql server 2008
If space is an issue on production machines then just create frequent transaction log backups.
You can use pandas it has some built in functions for comparison. So if you want to select values of "A" that are met by the conditions of "B" and "C" (assuming you want back a DataFrame pandas object)
df[['A']][df.B.gt(50) & df.C.ne(900)]
df[['A']]
will give you back column A in DataFrame format.
pandas 'gt' function will return the positions of column B that are greater than 50 and 'ne' will return the positions not equal to 900.
Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.
import pickle
class MyUser(object):
def __init__(self,name):
self.name = name
user = MyUser('Peter')
print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'
with open(filename,'wb') as file_object:
file_object.write(serialized)
with open(filename,'rb') as file_object:
raw_data = file_object.read()
deserialized = pickle.loads(raw_data)
print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)
print("------------")
Why not doing it in two lines?
var a, b, c, d; // All in the same scope
a = b = c = d = 1; // Set value to all.
The reason why, is to preserve the local scope on variable declarations, as this:
var a = b = c = d = 1;
will lead to the implicit declarations of b
, c
and d
on the window scope.
This worked for me
setInterval(ajax_query, 10000);
function ajax_query(){
//Call ajax here
}
You should iterate over the keys and get the values using square brackets.
See: How do I enumerate the properties of a javascript object?
EDIT: Obviously, this makes the question a duplicate.
Just to add my $.02 here, I ran into a similar issue just yesterday, where 168 of my tests were missing. I tried most everything in this post - most especially making sure my version(s) of NUnit were the same - all to no avail. I then remembered that I had my tests divided into playlists; and these do not update automatically as you add new tests. So, when I deleted the playlists, BAM!, all of my tests were back once more.
It could be something like that:
var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];
var arrays = [], size = 3;
while (a.length > 0)
arrays.push(a.splice(0, size));
console.log(arrays);

See splice Array's method.
You don't have to reset IIS, you can just recycle the app pool.
Official Python documentation: enumerate(iterable, start=0)
You don't need to write your own generator as other answers here suggest. The built-in Python standard library already contains a function that does exactly what you want:
>>> seasons = ['Spring', 'Summer', 'Fall', 'Winter']
>>> list(enumerate(seasons))
[(0, 'Spring'), (1, 'Summer'), (2, 'Fall'), (3, 'Winter')]
>>> list(enumerate(seasons, start=1))
[(1, 'Spring'), (2, 'Summer'), (3, 'Fall'), (4, 'Winter')]
The built-in function is equivalent to this:
def enumerate(sequence, start=0):
n = start
for elem in sequence:
yield n, elem
n += 1
I know this is kind of old but nobody yet mentioned numpy.array_split
:
import numpy as np
lst = range(50)
np.array_split(lst, 5)
# [array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]),
# array([10, 11, 12, 13, 14, 15, 16, 17, 18, 19]),
# array([20, 21, 22, 23, 24, 25, 26, 27, 28, 29]),
# array([30, 31, 32, 33, 34, 35, 36, 37, 38, 39]),
# array([40, 41, 42, 43, 44, 45, 46, 47, 48, 49])]
You can use Date.getTime()
which:
Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.
This means you can compare them just like numbers:
if (date1.getTime() <= date.getTime() && date.getTime() <= date2.getTime()) {
/*
* date is between date1 and date2 (both inclusive)
*/
}
/*
* when date1 = 2015-01-01 and date2 = 2015-01-10 then
* returns true for:
* 2015-01-01
* 2015-01-01 00:00:01
* 2015-01-02
* 2015-01-10
* returns false for:
* 2014-12-31 23:59:59
* 2015-01-10 00:00:01
*
* if one or both dates are exclusive then change <= to <
*/
Yes, some how the ajax call aborted. The cause may be following.
I like to give my input field a border, remove the outline on focus, and "outline" the border instead:
input {
border: 1px solid grey;
&:focus {
outline: none;
border-left: 1px solid violet;
}
}
You can also do it with a transparent border:
input {
border: 1px solid transparent;
&:focus {
outline: none;
border-left: 1px solid violet;
}
}
collect(Collectors.toList());
This is the call which you can use to convert any Stream to List.
more concretely:
List<String> myList = stream.collect(Collectors.toList());

If you're using the NetBeans IDE, right click on the project and choose Properties and go to sources, and you can change the Source/Binary Format to a lower JDK version.
After a lot of research I finally found the ultimate solution. It works even for floated elements. View Source
.element {
position: relative;
top: 50%;
transform: translateY(-50%); /* or try 50% */
}

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression
=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)
Same way for tolerance
=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")
In a similar scenario what worked for me was the following:
byte[] bytes = Convert.FromBase64String(Base64String);
ImageTagId.ImageUrl = "data:image/jpeg;base64," + Convert.ToBase64String(bytes);
ImageTagId
is the ID of the ASP image tag.
It says that the file C:\wamp\www\mysite\php\includes\dbconn.inc
doesn't exist, so the error is, you're missing the file.
Unfortunately I couldn't comment on the Sean Rose post due to insufficient reputation, however I had to amend the "public" role portion of the script as it didn't show SCHEMA-scoped permissions due to the (INNER) JOIN against sys.objects.

Searching this I found this project:

It seems to generate a lot of formats...
Here's another fix that works for me:
(event.target as HTMLInputElement).value
That should get rid of the error by letting TS know that event.target
is an HTMLInputElement
, which inherently has a value
. Before specifying, TS likely only knew that event
alone was an HTMLInputElement
, thus according to TS the keyed-in target
was some randomly mapped value that could be anything.
If you don't need these methods to return something, you could make them return Runnable objects.
private Runnable methodName (final int arg) {
return (new Runnable() {
public void run() {
// do stuff with arg
}
});
}
Then use it like:
private void otherMethodName (Runnable arg){
arg.run();
}
Some form of rounding is often unavoidable when dealing with floating point numbers. This is because numbers that you can express exactly in base 10 cannot always be expressed exactly in base 2 (which your computer uses).
For example:
>>> .1
0.10000000000000001
In this case, you're seeing .1 converted to a string using repr
:
>>> repr(.1)
'0.10000000000000001'
I believe python chops off the last few digits when you use str() in order to work around this problem, but it's a partial workaround that doesn't substitute for understanding what's going on.
>>> str(.1)
'0.1'
I'm not sure exactly what problems "rounding" is causing you. Perhaps you would do better with string formatting as a way to more precisely control your output?
e.g.
>>> '%.5f' % .1
'0.10000'
>>> '%.5f' % .12345678
'0.12346'
Well you can have
class MyClass
{
public:
static vector<char> a;
static class _init
{
public:
_init() { for(char i='a'; i<='z'; i++) a.push_back(i); }
} _initializer;
};
Don't forget (in the .cpp) this:
vector<char> MyClass::a;
MyClass::_init MyClass::_initializer;
The program will still link without the second line, but the initializer will not be executed.
Starting from Python 3.1, you can use importlib :
import importlib
foobar = importlib.import_module("foo-bar")
No, As others said, "There is no Pointer in PHP." and I add, there is nothing RAM_related in PHP.
And also all answers are clear. But there were points being left out that I could not resist!
At first I have to say that PHP is really powerful language, knowing there is a construct named "eval", so you can create your PHP code while running it! (really cool!)
although there is the danger of PHP_Injection which is far more destructive that SQL_Injection. Beware!
example:
Code:
$a='echo "Hello World.";';
eval ($a);
Output
Hello World.
So instead of using a pointer to act like another Variable, You Can Make A Variable From Scratch!
$GLOBAL variable is pretty useful, You can access all variables by using its keys.
example:
Code:
$three="Hello";$variable=" Amazing ";$names="World";
$arr = Array("three","variable","names");
foreach($arr as $VariableName)
echo $GLOBALS[$VariableName];
Output
Hello Amazing World
Note: Other superglobals can do the same trick in smaller scales.
You can add as much as '$'s you want before a variable, If you know what you're doing.
example:
Code:
$a="b";
$b="c";
$c="d";
$d="e";
$e="f";
echo $a."-";
echo $$a."-"; //Same as $b
echo $$$a."-"; //Same as $$b or $c
echo $$$$a."-"; //Same as $$$b or $$c or $d
echo $$$$$a; //Same as $$$$b or $$$c or $$d or $e
Output
b-c-d-e-f
Reference are so close to pointers, but you may want to check this link for more clarification.
example 1:
Code:
$a="Hello";
$b=&$a;
$b="yello";
echo $a;
Output
yello
example 2:
Code:
function junk(&$tion)
{$GLOBALS['a'] = &$tion;}
$a="-Hello World<br>";
$b="-To You As Well";
echo $a;
junk($b);
echo $a;
Output
-Hello World
-To You As Well
Hope It Helps.
I use the Azure Management console tool of CodePlex, with a very useful GUI, try it. You can save type some code.
