To return the whole table at once you could change the SELECT to:
SELECT ...
BULK COLLECT INTO T
FROM ...
This is only advisable for results that aren't excessively large, since they all have to be accumulated in memory before being returned; otherwise consider the pipelined function as suggested by Charles, or returning a REF CURSOR.
You don't "use" JavaScript variables in HTML. HTML is not a programming language, it's a markup language, it just "describes" what the page should look like.
If you want to display a variable on the screen, this is done with JavaScript.
First, you need somewhere for it to write to:
<body>
<p id="output"></p>
</body>
Then you need to update your JavaScript code to write to that <p>
tag. Make sure you do so after the page is ready.
<script>
window.onload = function(){
var name = prompt("What's your name?");
var lengthOfName = name.length
document.getElementById('output').innerHTML = lengthOfName;
};
</script>
window.onload = function() {_x000D_
var name = prompt("What's your name?");_x000D_
var lengthOfName = name.length_x000D_
_x000D_
document.getElementById('output').innerHTML = lengthOfName;_x000D_
};
_x000D_
<p id="output"></p>

Hashes can not be decrypted check this out.
If you want to encrypt-decrypt, use a two way encryption function of your database like - AES_ENCRYPT (in MySQL).
But I'll suggest CRYPT_BLOWFISH algorithm for storing password. Read this- http://php.net/manual/en/function.crypt.php and http://us2.php.net/manual/en/function.password-hash.php
For Blowfish by crypt()
function -
crypt('String', '$2a$07$twentytwocharactersalt$');
password_hash
will be introduced in PHP 5.5.
$options = [
'cost' => 7,
'salt' => 'BCryptRequires22Chrcts',
];
password_hash("rasmuslerdorf", PASSWORD_BCRYPT, $options);
Once you have stored the password, you can then check if the user has entered correct password by hashing it again and comparing it with the stored value.
Using d.Keys()(i)
method is a very bad idea, because on each call it will re-create a new array (you will have significant speed reduction).
Here is an analogue of Scripting.Dictionary
called "Hash Table" class from @TheTrick, that support such enumerator: http://www.cyberforum.ru/blogs/354370/blog2905.html
Dim oDict As clsTrickHashTable
Sub aaa()
Set oDict = New clsTrickHashTable
oDict.Add "a", "aaa"
oDict.Add "b", "bbb"
For i = 0 To oDict.Count - 1
Debug.Print oDict.Keys(i) & " - " & oDict.Items(i)
Next
End Sub
Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).
Anyways, if you're already planning on using MSYS2, there's no need for that installer.
Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).
After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit
or MSYS2 32-bit
in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu
, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).
Install a toolchain
a) for 32-bit:
pacman -S mingw-w64-i686-gcc
b) for 64-bit:
pacman -S mingw-w64-x86_64-gcc
install any libraries/tools you may need. You can search the repositories by doing
pacman -Ss name_of_something_i_want_to_install
e.g.
pacman -Ss gsl
and install using
pacman -S package_name_of_something_i_want_to_install
e.g.
pacman -S mingw-w64-x86_64-gsl
and from then on the GSL library is automatically found by your MinGW-w64 64-bit compiler!
Open a MinGW-w64 shell:
a) To build 32-bit things, open the "MinGW-w64 32-bit Shell"
b) To build 64-bit things, open the "MinGW-w64 64-bit Shell"
Verify that the compiler is working by doing
gcc -v
If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add <MSYS2 root>/mingw32/bin
or <MSYS2 root>/mingw64/bin
to your PATH
.
Whatever approach you take, make sure in the end that you have an updated version of curl and libcurl. You can do curl --version
and see the versions.
Here's what I did to get the latest curl version installed in Ubuntu:
sudo add-apt-repository "deb http://mirrors.kernel.org/ubuntu wily main"
sudo apt-get update
sudo apt-get install curl
A key point that I find missing in the above answers is that urllib returns an object of type <class http.client.HTTPResponse>
whereas requests
returns <class 'requests.models.Response'>
.
Due to this, read() method can be used with urllib
but not with requests
.
P.S. : requests
is already rich with so many methods that it hardly needs one more as read()

In Kotlin there is now a cleaner way by using lambda functions, no need for interfaces:
class MyAdapter(val adapterOnClick: (Any) -> Unit) {
fun setItem(item: Any) {
myButton.setOnClickListener { adapterOnClick(item) }
}
}
class MyActivity {
override fun onCreate(savedInstanceState: Bundle?) {
var myAdapter = MyAdapter { item -> doOnClick(item) }
}
fun doOnClick(item: Any) {
}
}
You have a bad table design. You can't autoincrement a string, that doesn't make any sense. You have basically two options:
1.) change type of ID to int
instead of string
2.) not recommended!!! - handle autoincrement by yourself. You first need to get the latest value from the database, parse it to the integer, increment it and attach it to the entity as a string again. VERY BAD idea
First option requires to change every table that has a reference to this table, BUT it's worth it.
Part One - Polyfill
For browsers that haven't implemented it, a polyfill for array.find
. Courtesy of MDN.
if (!Array.prototype.find) {
Array.prototype.find = function(predicate) {
if (this == null) {
throw new TypeError('Array.prototype.find called on null or undefined');
}
if (typeof predicate !== 'function') {
throw new TypeError('predicate must be a function');
}
var list = Object(this);
var length = list.length >>> 0;
var thisArg = arguments[1];
var value;
for (var i = 0; i < length; i++) {
value = list[i];
if (predicate.call(thisArg, value, i, list)) {
return value;
}
}
return undefined;
};
}
Part Two - Interface
You need to extend the open Array interface to include the find
method.
interface Array<T> {
find(predicate: (search: T) => boolean) : T;
}
When this arrives in TypeScript, you'll get a warning from the compiler that will remind you to delete this.
Part Three - Use it
The variable x
will have the expected type... { id: number }
var x = [{ "id": 1 }, { "id": -2 }, { "id": 3 }].find(myObj => myObj.id < 0);
A part from @djechlin answer, you should change the rows and columns. Since you are taken as 7 rows and 5 columns, but actually you want is 7 columns and 5 rows.
Do this way:-
int twoDm[][]= new int[5][7];
for(i=0;i<5;i++){
for(j=0;j<7;j++) {
System.out.print(twoDm[i][j]+" ");
}
System.out.println("");
}
The comma expression takes on the value of the last (eg. right-most) expression.
So in your first loop, the only controlling expression is i<=5
; and j>=0
is ignored.
In the second loop, j>=0
controls the loop, and i<=5
is ignored.
As for a reason... there is no reason. This code is just wrong. The first part of the comma-expressions does nothing except confuse programmers. If a serious programmer wrote this, they should be ashamed of themselves and have their keyboard revoked.
Yes, let's use Select
as an example
sample code: Columns("A").select
How to loop through Columns:
Method 1: (You can use index to replace the Excel Address)
For i = 1 to 100
Columns(i).Select
next i
Method 2: (Using the address)
For i = 1 To 100
Columns(Columns(i).Address).Select
Next i
EDIT: Strip the Column for OP
columnString = Replace(Split(Columns(27).Address, ":")(0), "$", "")
e.g. you want to get the 27th Column --> AA, you can get it this way
I wasn't able to create a new virtualenv on top of the old one. But there are tools in pip which make it much faster to re-install requirements into a brand new venv. Pip can build each of the items in your requirements.txt into a wheel package, and store that in a local cache. When you create a new venv and run pip install in it, pip will automatically use the prebuilt wheels if it finds them. Wheels install much faster than running setup.py for each module.
My ~/.pip/pip.conf looks like this:
[global]
download-cache = /Users/me/.pip/download-cache
find-links =
/Users/me/.pip/wheels/
[wheel]
wheel-dir = /Users/me/.pip/wheels
I install wheel (pip install wheel
), then run pip wheel -r requirements.txt
. This stores the built wheels in the wheel-dir in my pip.conf.
From then on, any time I pip install any of these requirements, it installs them from the wheels, which is pretty quick.
I didn't understand your problem clearly but I think this is what you're looking for(Based on my understanding)
person = {"name"=>"BillGates", "company_name"=>"Microsoft", "position"=>"Chairman"}
person.delete_if {|key, value| key == "name"} #doing something if the key == "something"
Output: {"company_name"=>"Microsoft", "position"=>"Chairman"}
If two different views are sharing the same model (for instance, maybe one is for mobile output and one is regular), it could be nice to have the string reside in a single place: as metadata on the ViewModel.
Additionally, if you had an inherited version of the model that necessitated a different display, it could be useful. For instance:
public class BaseViewModel
{
[Display(Name = "Basic Name")]
public virtual string Name { get; set; }
}
public class OtherViewModel : BaseViewModel
{
[Display(Name = "Customized Inherited Name")]
public override string Name { get; set; }
}
I'll admit that that example is pretty contrived...
Those are the best arguments in favor of using the attribute that I can come up with. My personal opinion is that, for the most part, that sort of thing is best left to the markup.
I suggest a custom alias on you .gitconfig
.
You have to way to do:
1) With git command:
git config --global alias.check-file <command>
2) Editing ~/.gitconfig
and add this line on alias section:
[alias]
check-file = "!f() { if [ $# -eq 0 ]; then echo 'Filename missing!'; else tracked=$(git ls-files ${1}); if [[ -z ${tracked} ]]; then echo 'File not tracked'; else echo 'File tracked'; fi; fi; }; f"
Once launched command (1) or saved file (2), on your workspace you can test it:
$ git check-file
$ Filename missing
$ git check-file README.md
$ File tracked
$ git check-file foo
$ File not tracked
I spent a while messing around with this problem, because no solution I found actually worked, strangely enough! The working directory is frequently not the directory of the JAR, especially if a JAR (or any program, for that matter) is run from the Start Menu under Windows. So here is what I did, and it works for .class files run from outside a JAR just as well as it works for a JAR. (I only tested it under Windows 7.)
try {
//Attempt to get the path of the actual JAR file, because the working directory is frequently not where the file is.
//Example: file:/D:/all/Java/TitanWaterworks/TitanWaterworks-en.jar!/TitanWaterworks.class
//Another example: /D:/all/Java/TitanWaterworks/TitanWaterworks.class
PROGRAM_DIRECTORY = getClass().getClassLoader().getResource("TitanWaterworks.class").getPath(); // Gets the path of the class or jar.
//Find the last ! and cut it off at that location. If this isn't being run from a jar, there is no !, so it'll cause an exception, which is fine.
try {
PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(0, PROGRAM_DIRECTORY.lastIndexOf('!'));
} catch (Exception e) { }
//Find the last / and cut it off at that location.
PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(0, PROGRAM_DIRECTORY.lastIndexOf('/') + 1);
//If it starts with /, cut it off.
if (PROGRAM_DIRECTORY.startsWith("/")) PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(1, PROGRAM_DIRECTORY.length());
//If it starts with file:/, cut that off, too.
if (PROGRAM_DIRECTORY.startsWith("file:/")) PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(6, PROGRAM_DIRECTORY.length());
} catch (Exception e) {
PROGRAM_DIRECTORY = ""; //Current working directory instead.
}

Note: Spread syntax effectively goes one level deep while copying an array. Therefore, it may be unsuitable for copying multidimensional arrays as the following example shows (it's the same with Object.assign() and spread syntax).
Personally, I suggest using Lodash's cloneDeep function for multi-level object/array cloning.
Here is a working example:
const arr1 = [{ 'a': 1 }];_x000D_
_x000D_
const arr2 = [...arr1];_x000D_
_x000D_
const arr3 = _.clone(arr1);_x000D_
_x000D_
const arr4 = arr1.slice();_x000D_
_x000D_
const arr5 = _.cloneDeep(arr1);_x000D_
_x000D_
const arr6 = [...{...arr1}]; // a bit ugly syntax but it is working!_x000D_
_x000D_
_x000D_
// first level_x000D_
console.log(arr1 === arr2); // false_x000D_
console.log(arr1 === arr3); // false_x000D_
console.log(arr1 === arr4); // false_x000D_
console.log(arr1 === arr5); // false_x000D_
console.log(arr1 === arr6); // false_x000D_
_x000D_
// second level_x000D_
console.log(arr1[0] === arr2[0]); // true_x000D_
console.log(arr1[0] === arr3[0]); // true_x000D_
console.log(arr1[0] === arr4[0]); // true_x000D_
console.log(arr1[0] === arr5[0]); // false_x000D_
console.log(arr1[0] === arr6[0]); // false

Make an exception handler like this,
private int ConvertIntoNumeric(String xVal)
{
try
{
return Integer.parseInt(xVal);
}
catch(Exception ex)
{
return 0;
}
}
.
.
.
.
int xTest = ConvertIntoNumeric("N/A"); //Will return 0
This because a char
is stored at all effects as a 8-bit number. Speaking about a negative or positive char
doesn't make sense if you consider it an ASCII code (which can be just signed*) but makes sense if you use that char
to store a number, which could be in range 0-255 or in -128..127 according to the 2-complement representation.
*: it can be also unsigned, it actually depends on the implementation I think, in that case you will have access to extended ASCII charset provided by the encoding used
If you want to do multiple commands, you could use:
for I in `ls *.sql`
do
grep "foo" $I >> foo.log
grep "bar" $I >> bar.log
done
Rising to @Ankan-Zerob's challenge, this is my estimate of the maximum length which can be stored in each text type measured in words:
Type | Bytes | English words | Multi-byte words
-----------+---------------+---------------+-----------------
TINYTEXT | 255 | ±44 | ±23
TEXT | 65,535 | ±11,000 | ±5,900
MEDIUMTEXT | 16,777,215 | ±2,800,000 | ±1,500,000
LONGTEXT | 4,294,967,295 | ±740,000,000 | ±380,000,000
In English, 4.8 letters per word is probably a good average (eg norvig.com/mayzner.html), though word lengths will vary according to domain (e.g. spoken language vs. academic papers), so there's no point being too precise. English is mostly single-byte ASCII characters, with very occasional multi-byte characters, so close to one-byte-per-letter. An extra character has to be allowed for inter-word spaces, so I've rounded down from 5.8 bytes per word. Languages with lots of accents such as say Polish would store slightly fewer words, as would e.g. German with longer words.
Languages requiring multi-byte characters such as Greek, Arabic, Hebrew, Hindi, Thai, etc, etc typically require two bytes per character in UTF-8. Guessing wildly at 5 letters per word, I've rounded down from 11 bytes per word.
CJK scripts (Hanzi, Kanji, Hiragana, Katakana, etc) I know nothing of; I believe characters mostly require 3 bytes in UTF-8, and (with massive simplification) they might be considered to use around 2 characters per word, so they would be somewhere between the other two. (CJK scripts are likely to require less storage using UTF-16, depending).
This is of course ignoring storage overheads etc.
If somebody will find that it's still not working under non-admin users:
Example error:
ImportError: No module named iso8601
you need to set '--always-unzip' option for easy_install:
easy_install --always-unzip python-keystoneclient
It will unzip your egg files and will allow import to find em.
Have a go with this, as this is how I would do it :)
SELECT *
FROM fab_scheduler
WHERE custid = '123456'
AND CURDATE() = DATE(DATE_ADD(eventdate, INTERVAL 1 DAY))
$(document.createElement("img")).attr({

This is quite simple.
Assuming the data is stored in a column called A in a table called T, you can use
select A, count(A) from T group by A
function printCrossword(printContainer) {
var DocumentContainer = getElement(printContainer);
var WindowObject = window.open('', "PrintWindow", "width=5,height=5,top=200,left=200,toolbars=no,scrollbars=no,status=no,resizable=no");
WindowObject.document.writeln(DocumentContainer.innerHTML);
WindowObject.document.close();
WindowObject.focus();
WindowObject.print();
WindowObject.close();
}

Your syntax is incorrect. To make a literal map (as a pseudo-constant), you can do:
var romanNumeralDict = 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",
}
Inside a func
you can declare it like:
romanNumeralDict := map[int]string{
...
And in Go there is no such thing as a constant map. More information can be found here.
ID is suitable for the elements which appears only once Like Logo sidebar container
And Class is suitable for the elements which has same UI but they can be appear more than once. Like
.feed in the #feeds Container
Add these two file in your app.module.ts
import { FileTransfer } from '@ionic-native/file-transfer';
import { File } from '@ionic-native/file';
after that declare these to in provider..
providers: [
Api,
Items,
User,
Camera,
File,
FileTransfer];
This is work for me.
Use preventDefault()
to stop the event of submit button and in ajax call success submit the form using submit()
:
$('#btnSave').click(function (e) {
e.preventDefault(); // <------------------ stop default behaviour of button
var element = this;
$.ajax({
url: "/Home/SaveDetailedInfo",
type: "POST",
data: JSON.stringify({ 'Options': someData}),
dataType: "json",
traditional: true,
contentType: "application/json; charset=utf-8",
success: function (data) {
if (data.status == "Success") {
alert("Done");
$(element).closest("form").submit(); //<------------ submit form
} else {
alert("Error occurs on the Database level!");
}
},
error: function () {
alert("An error has occured!!!");
}
});
});
Simplified example (with counter):
With Me.lstbox
.ColumnCount = 2
.ColumnWidths = "60;60"
.AddItem
.List(i, 0) = Company_ID
.List(i, 1) = Company_name
i = i + 1
end with
Make sure to start the counter with 0, not 1 to fill up a listbox.
I found a good solution for adding/updating the CA certificates on RHEL/CentOS 6 which is the root cause reported issue.
Since they become outdated distros, the cacert authorities in that system has not been updated until executing the command sudo yum update
.
Didn't realize the issue until the GIT_CURL_VERBOSE mode shows the cacert path issue.
A map will not keep insertion order. Use *(myMap.begin())
to get the value of the first pair (the one with the smallest key when ordered).
You could also do myMap.begin()->first
to get the key and myMap.begin()->second
to get the value.
Creating firewall rules
Please review the firewall rule components [1] if you are unfamiliar with firewall rules in GCP. Firewall rules are defined at the network level, and only apply to the network where they are created; however, the name you choose for each of them must be unique to the project.
For Cloud Console:
Specify the Targets of the rule.
For an ingress rule, specify the Source filter:
For an egress rule, specify the Destination filter:
Define the Protocols and ports to which the rule will apply:
Select Allow all or Deny all, depending on the action, to have the rule apply to all protocols and ports.
Define specific protocols and ports:
(Optional) You can create the firewall rule but not enforce it by setting its enforcement state to disabled. Click Disable rule, then select Disabled.
(Optional) You can enable firewall rules logging:
Click Create.

I wanted a more exact and useful answer to this question. Here's the real answer (adjust accordingly if you want a byte array specifically; obviously the math will be off by a factor of 8 bits : 1 byte
):
class BitArray {
constructor(bits = 0) {
this.uints = new Uint32Array(~~(bits / 32));
}
getBit(bit) {
return (this.uints[~~(bit / 32)] & (1 << (bit % 32))) != 0 ? 1 : 0;
}
assignBit(bit, value) {
if (value) {
this.uints[~~(bit / 32)] |= (1 << (bit % 32));
} else {
this.uints[~~(bit / 32)] &= ~(1 << (bit % 32));
}
}
get size() {
return this.uints.length * 32;
}
static bitsToUints(bits) {
return ~~(bits / 32);
}
}
Usage:
let bits = new BitArray(500);
for (let uint = 0; uint < bits.uints.length; ++uint) {
bits.uints[uint] = 457345834;
}
for (let bit = 0; bit < 50; ++bit) {
bits.assignBit(bit, 1);
}
str = '';
for (let bit = bits.size - 1; bit >= 0; --bit) {
str += bits.getBit(bit);
}
str;
Output:
"00011011010000101000101100101010
00011011010000101000101100101010

Note: This class is really slow to e.g. assign bits (i.e. ~2s per 10 million assignments) if it's created as a global variable, at least in the Firefox 76.0 Console on Linux... If, on the other hand, it's created as a variable (i.e. let bits = new BitArray(1e7);
), then it's blazingly fast (i.e. ~300ms per 10 million assignments)!
For more info, see here:
Note that I used Uint32Array because there's no way to directly have a bit/byte array (that you can interact with directly) and because even though there's a BigUint64Array
, JS only supports 32 bits:
Bitwise operators treat their operands as a sequence of 32 bits
...
The operands of all bitwise operators are converted to...32-bit integers
For people using private GitLabs, here's a snippet that may help: https://gist.github.com/MicahParks/1ba2b19c39d1e5fccc3e892837b10e21
Also pasted below:
The go
command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.
This assumes your private GitLab is hosted at privategitlab.company.com
.
The following environment variables are recommended:
export GO111MODULE=on
export GOPRIVATE=privategitlab.company.com
The above lines might fit best in your shell startup, like a ~/.bashrc
.
GO111MODULE=on
tells Golang command line tools you are using modules. I have not tested this with projects not using
Golang modules on a private GitLab.
GOPRIVATE=privategitlab.company.com
tells Golang command line tools to not use public internet resources for the hostnames
listed (like the public module proxy).
To future proof these instructions, please follow this guide from the GitLab docs.
I know that the read_api
scope is required for Golang command line tools to work, and I may suspect read_repository
as
well, but have not confirmed this.
~/.netrc
In order for the Golang command line tools to authenticate to GitLab, a ~/.netrc
file is best to use.
To create the file if it does not exist, run the following commands:
touch ~/.netrc
chmod 600 ~/.netrc
Now edit the contents of the file to match the following:
machine privategitlab.company.com login USERNAME_HERE password TOKEN_HERE
Where USERNAME_HERE

Do not set up a global git configuration with something along the lines of this:
git config --global url."[email protected]:".insteadOf "https://privategitlab.company.com"
I beleive at the time of writing this, the SSH git is not fully supported by Golang command line tools and this may cause
conflicts with the ~/.netrc
.
For regular use of the git
tool, not the Golang command line tools, it's convient to have a ~/.ssh/config
file set up.
In order to do this, run the following commands:
mkdir ~/.ssh
chmod 700 ~/.ssh
touch ~/.ssh/config
chmod 600 ~/.ssh/config
Please note the permissions on the files and directory above are essentail for SSH to work in it's default configuration on most Linux systems.
Then, edit the ~/.ssh/config
file to match the following:
Host privategitlab.company.com
Hostname privategitlab.company.com
User USERNAME_HERE
IdentityFile ~/.ssh/id_rsa
Please note the spacing in the above file matters and will invalidate the file if it is incorrect.
Where USERNAME_HERE
is your GitLab username and ~/.ssh/id_rsa
is the path to your SSH private key in your file system.
You've already uploaded its public key to GitLab. Here are some instructions.
You can add a separate UIView
with 1 point height and gray background color to self.view
and position it right below toScrollView
.
EDIT: Unless you have a good reason (want to use some services of UIView which are not offered by CALayer), you should use CALayer as @MattDiPasquale suggests. UIView has a greater overhead, which might not be a problem in most cases, but still, the other solution is more elegant.
You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.
This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.

Oh, I see now: only the solution 3 with map() fits with the title of the question.
If you have changed your assembly version or copied a different version of the managed library stated in the error you may also have previously compiled files referencing the wrong version. A 'Rebuild All' (or deleting you 'bin and 'obj' folders as mentioned in an earlier comment) should fix this case.
This might seem like overkill, but if in another case you were trying to load a canvas from js (like I am doing), you could use a setInterval function and an if statement to constantly check if the canvas has loaded.
//set up the interval
var thisInterval = setInterval(function{
//this if statment checks if the id "thisCanvas" is linked to something
if(document.getElementById("thisCanvas") != null){
//do what you want
//clearInterval() will remove the interval if you have given your interval a name.
clearInterval(thisInterval)
}
//the 500 means that you will loop through this every 500 milliseconds (1/2 a second)
},500)
(In this example the canvas I am trying to load has an id of "thisCanvas")

Default Set in Java is, unfortunately, not designed to provide a "get" operation, as jschreiner accurately explained.
The solutions of using an iterator to find the element of interest (suggested by dacwe) or to remove the element and re-add it with its values updated (suggested by KyleM), could work, but can be very inefficient.
Overriding the implementation of equals so that non-equal objects are "equal", as stated correctly by David Ogren, can easily cause maintenance problems.
And using a Map as an explicit replacement (as suggested by many), imho, makes the code less elegant.
If the goal is to get access to the original instance of the element contained in the set (hope I understood correctly your use case), here is another possible solution.
I personally had your same need while developing a client-server videogame with Java. In my case, each client had copies of the components stored in the server and the problem was whenever a client needed to modify an object of the server.
Passing an object through the internet meant that the client had different instances of that object anyway. In order to match this "copied" instance with the original one, I decided to use Java UUIDs.
So I created an abstract class UniqueItem, which automatically gives a random unique id to each instance of its subclasses.
This UUID is shared between the client and the server instance, so this way it could be easy to match them by simply using a Map.
However directly using a Map in a similar usecase was still inelegant. Someone might argue that using an Map might be more complicated to mantain and handle.
For these reasons I implemented a library called MagicSet, that makes the usage of an Map "transparent" to the developer.
https://github.com/ricpacca/magicset
Like the original Java HashSet, a MagicHashSet (which is one of the implementations of MagicSet provided in the library) uses a backing HashMap, but instead of having elements as keys and a dummy value as values, it uses the UUID of the element as key and the element itself as value. This does not cause overhead in the memory use compared to a normal HashSet.
Moreover, a MagicSet can be used exactly as a Set, but with some more methods providing additional functionalities, like getFromId(), popFromId(), removeFromId(), etc.
The only requirement to use it is that any element that you want to store in a MagicSet needs to extend the abstract class UniqueItem.
Here is a code example, imagining to retrieve the original instance of a city from a MagicSet, given another instance of that city with the same UUID (or even just its UUID).
class City extends UniqueItem {
// Somewhere in this class
public void doSomething() {
// Whatever
}
}
public class GameMap {
private MagicSet<City> cities;
public GameMap(Collection<City> cities) {
cities = new MagicHashSet<>(cities);
}
/*
* cityId is the UUID of the city you want to retrieve.
* If you have a copied instance of that city, you can simply
* call copiedCity.getId() and pass the return value to this method.
*/
public void doSomethingInCity(UUID cityId) {
City city = cities.getFromId(cityId);
city.doSomething();
}
// Other methods can be called on a MagicSet too
}
Try writing it in a new file..
f = open(filename, 'r+')
f2= open(filename2,'a+')
text = f.read()
text = re.sub('foobar', 'bar', text)
f.seek(0)
f.close()
f2.write(text)
fw.close()
If length
is undefined you can use:
function count(array){
var c = 0;
for(i in array) // in returns key, not object
if(array[i] != undefined)
c++;
return c;
}
var total = count(array);
Are you looking for this?
ContactNumbers = new List<ContactNumber>(){ new ContactNumber("555-5555"),
new ContactNumber("555-1234"),
new ContactNumber("555-5678") };
As mentioned in the above answer, by updating the bashrc file you can run the pycharm.sh from anywhere on the linux terminal.
But if you love the icon and wants the Desktop shortcuts for the Pycharm on Ubuntu OS then follow the Below steps,
Quick way to create Pycharm launcher.
1. Start Pycharm using the pycharm.sh cmd from anywhere on the terminal or start the pycharm.sh located under bin folder of the pycharm artifact.
2. Once the Pycharm application loads, navigate to tools menu and select “Create Desktop Entry..”
3. Check the box if you want the launcher for all users.
4. If you Check the box i.e “Create entry for all users”, you will be asked for your password.
5. A message should appear informing you that it was successful.
6. Now Restart Pycharm application and you will find Pycharm in Unity dash and Application launcher.."

From the documentation,
Positioning your Toast
A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the
setGravity(int, int, int)
method. This accepts three parameters: aGravity
constant, anx-position
offset, and ay-position
offset.For example, if you decide that the toast should appear in the top-left corner, you can set the gravity like this:
toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);
If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.
It is recommended to use at least 0.12.2.1.
Starting from wkhtmltopdf >= 0.12.2 it doesn't require X server or emulation anymore. You can download new version from http://wkhtmltopdf.org/downloads.html

nothing comes out of it, meaning it does not exist and it wasn't set at all...
Your repo is yours, what goes on in it is entirely your business until you push or (allow a) fetch or clone. When you deleted your windows repo -- that folder didn't represent your local repo, it was your actual local repo, you deleted everything done in it that was never pushed, fetched or cloned.
edit: Ah, okay, I think I see what's going on here: you pushed to your linux repo but it's not bare and you never worked in it.
Instead of git log
, do git log --all
. Or git checkout
some-branch-name
.
Then try cloning the repo locally, on your linux box; I bet it works. What are you using to serve your repo on linux? Try cd'ing into its .git directory and git daemon --base-path=. --export-all
, if that just sits there then go to your windows box and try git clone git://your.linux.box.ip
, if the daemon complains it can't bind add --port=54345
to the daemon invoke and :54345
to the clone url.
Does it have to be specifically an InputStreamReader? How about using StringReader?
Otherwise, you could use StringBufferInputStream, but it's deprecated because of character conversion issues (which is why you should prefer StringReader).
You can specify ord to get the L1 norm. To avoid zero division I use eps, but that's maybe not great.
def normalize(v):
norm=np.linalg.norm(v, ord=1)
if norm==0:
norm=np.finfo(v.dtype).eps
return v/norm
The following query will find the documents with required string case insensitively and with global occurrence also

Sounds to me like at least one of those tables has defined UserID
as a uniqueidentifier
, not an int
. Did you check the data in each table? What does SELECT TOP 1 UserID FROM
each table yield? An int
or a GUID
?
EDIT
I think you have built a procedure based on all tables that contain a column named UserID. I think you should not have included the aspnet_Membership
table in your script, since it's not really one of "your" tables.
If you meant to design your tables around the aspnet_Membership
database, then why are the rest of the columns int
when that table clearly uses a uniqueidentifier
for the UserID
column?
This is a swiss-armyknife function you can use:
function table.find(t, val, recursive, metatables, keys, returnBool)
if (type(t) ~= "table") then
return nil
end
local checked = {}
local _findInTable
local _checkValue
_checkValue = function(v)
if (not checked[v]) then
if (v == val) then
return v
end
if (recursive and type(v) == "table") then
local r = _findInTable(v)
if (r ~= nil) then
return r
end
end
if (metatables) then
local r = _checkValue(getmetatable(v))
if (r ~= nil) then
return r
end
end
checked[v] = true
end
return nil
end
_findInTable = function(t)
for k,v in pairs(t) do
local r = _checkValue(t, v)
if (r ~= nil) then
return r
end
if (keys) then
r = _checkValue(t, k)
if (r ~= nil) then
return r
end
end
end
return nil
end
local r = _findInTable(t)
if (returnBool) then
return r ~= nil
end
return r
end
You can use it to check if a value exists:
local myFruit = "apple"
if (table.find({"apple", "pear", "berry"}, myFruit)) then
print(table.find({"apple", "pear", "berry"}, myFruit)) -- 1
You can use it to find the key:
local fruits = {
apple = {color="red"},
pear = {color="green"},
}
local myFruit = fruits.apple
local fruitName = table.find(fruits, myFruit)
print(fruitName) -- "apple"
I hope the recursive
parameter speaks for itself.
The metatables
parameter allows you to search metatables as well.
The keys
parameter makes the function look for keys in the list. Of course that would be useless in Lua (you can just do fruits[key]
) but together with recursive
and metatables
, it becomes handy.
The returnBool
parameter is a safe-guard for when you have tables that have false
as a key in a table (Yes that's possible: fruits = {false="apple"}
)
Actually you can set custom text to that little blue button. In the xml file just use
android:imeActionLabel="whatever"
on your EditText.
Or in the java file use
etEditText.setImeActionLabel("whatever", EditorInfo.IME_ACTION_DONE);
I arbitrarily choose IME_ACTION_DONE as an example of what should go in the second parameter for this function. A full list of these actions can be found here.
It should be noted that this will not cause text to appear on all keyboards on all devices. Some keyboards do not support text on that button (e.g. swiftkey). And some devices don't support it either. A good rule is, if you see text already on the button, this will change it to whatever you'd want.
you can just cast it
int dbValue = 2;
EnumDisplayStatus enumValue = (EnumDisplayStatus)dbValue;
string stringName = enumValue.ToString(); //Visible
ah.. kent beat me to it :)
I was able to figure out the solution:
start notepad "myfile.txt"

I'm using something like this:
$.when(
$.each(yourArray, function (key, value) {

})
).then(function () {

Try this:
image = cv2.imread("img/Demo.jpg")
image = cv2.resize(image,(240,240))
The image
is now resized. Displaying it will render in 240x240.
A simple function that blits an image front
onto an image back
and returns the result. It works with both 3 and 4-channel images and deals with the alpha channel. Overlaps are handled as well.
The output image has the same size as back, but always 4 channels.
The output alpha channel is given by (u+v)/(1+uv) where u,v are the alpha channels of the front and back image and -1 <= u,v <= 1. Where there is no overlap with front, the alpha value from back is taken.
import cv2
def merge_image(back, front, x,y):
# convert to rgba
if back.shape[2] == 3:
back = cv2.cvtColor(back, cv2.COLOR_BGR2BGRA)
if front.shape[2] == 3:
front = cv2.cvtColor(front, cv2.COLOR_BGR2BGRA)
# crop the overlay from both images
bh,bw = back.shape[:2]
fh,fw = front.shape[:2]
x1, x2 = max(x, 0), min(x+fw, bw)
y1, y2 = max(y, 0), min(y+fh, bh)
front_cropped = front[y1-y:y2-y, x1-x:x2-x]
back_cropped = back[y1:y2, x1:x2]
alpha_front = front_cropped[:,:,3:4] / 255
alpha_back = back_cropped[:,:,3:4] / 255
# replace an area in result with overlay
result = back.copy()
print(f'af: {alpha_front.shape}\nab: {alpha_back.shape}\nfront_cropped: {front_cropped.shape}\nback_cropped: {back_cropped.shape}')
result[y1:y2, x1:x2, :3] = alpha_front * front_cropped[:,:,:3] + alpha_back * back_cropped[:,:,:3]
result[y1:y2, x1:x2, 3:4] = (alpha_front + alpha_back) / (1 + alpha_front*alpha_back) * 255
return result

I'd use onMouseOver & onMouseOut. Cause in React
The onMouseEnter and onMouseLeave events propagate from the element being left to the one being entered instead of ordinary bubbling and do not have a capture phase.
Here it is in the React documentation for mouse events.

As mentioned in the other answers MOQ cannot mock static methods and, as a general rule, one should avoid statics where possible.
Sometimes it is not possible. One is working with legacy or 3rd party code or with even with the BCL methods that are static.
A possible solution is to wrap the static in a proxy with an interface which can be mocked
public interface IFileProxy {
void Delete(string path);
}
public class FileProxy : IFileProxy {
public void Delete(string path) {
System.IO.File.Delete(path);
}
}
public class MyClass {
private IFileProxy _fileProxy;
public MyClass(IFileProxy fileProxy) {
_fileProxy = fileProxy;
}
public void DoSomethingAndDeleteFile(string path) {
// Do Something with file
// ...
// Delete
System.IO.File.Delete(path);
}
public void DoSomethingAndDeleteFileUsingProxy(string path) {
// Do Something with file
// ...
// Delete
_fileProxy.Delete(path);
}
}
The downside is that the ctor can become very cluttered if there are a lot of proxies (though it could be argued that if there are a lot of proxies then the class may be trying to do too much and could be refactored)
Another possibility is to have a 'static proxy' with different implementations of the interface behind it
public static class FileServices {
static FileServices() {
Reset();
}
internal static IFileProxy FileProxy { private get; set; }
public static void Reset(){
FileProxy = new FileProxy();
}
public static void Delete(string path) {
FileProxy.Delete(path);
}
}
Our method now becomes
public void DoSomethingAndDeleteFileUsingStaticProxy(string path) {
// Do Something with file
// ...
// Delete
FileServices.Delete(path);
}
For testing, we can set the FileProxy property to our mock. Using this style reduces the number of interfaces to be injected but makes dependencies a bit less obvious (though no more so than the original static calls I suppose).
ObjectPath is a query language similar to XPath or JSONPath, but much more powerful thanks to embedded arithmetic calculations, comparison mechanisms and built-in functions. See the syntax:

$..shoes.*[color is "red" and price < 50]
First I think there should be a afterShowing
method in the datepicker object, where you could change the position after jquery has done all its voodoo in the _showDatepicker
method. Additionally, a parameter called preferedPosition
would be also desirable, so you could set it and jquery modify it in case the dialog is rendered outside the viewport.
There's a "trick" to do this last thing. If you study the _showDatepicker
method, you will see the use of a private variable $.datepikcer._pos
. That variable will be setup if nobody has set it up before. If you modify that variable before showing the dialog, Jquery will take it and will try to allocate the dialog in that position, and if it renders out of the screen, it will adjust it to make sure it is visible. Sounds good, eh?
Problem is; _pos
is private, but if you don't mind that. You can:
$('input.date').datepicker({
beforeShow: function(input, inst)
{
$.datepicker._pos = $.datepicker._findPos(input); //this is the default position
$.datepicker._pos[0] = whatever; //left
$.datepicker._pos[1] = whatever; //top
}
});
But be careful of Jquery-ui updates, because a change in the internal implementation of the _showDatepicker
might break your code.

A project is not exactly the same thing as an executable jar file.

Object doesn't support this property or method.
Think of it like if anything after the dot is called on an object. It's like a chain.
An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot .
you get intelli-sense (that white dropdown) trying to help you pick the correct action.
(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)
Type this much anywhere in your code area
Dim a As Worksheets
a.
you get help from VBE, it's a little dropdown called Intelli-sense
It lists all available actions that particular object exposes to any user. You can't see the .Selection
member of the Worksheets()
class. That's what the error tells you exactly.
Object doesn't support this property or method.
If you look at the example on MSDN
Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count
It activates
the sheet first then calls the Selection...
it's not connected together because Selection
is not a member of Worksheets()
class. Simply, you can't prefix the Selection
What about
Sub DisplayColumnCount()
Dim iAreaCount As Integer
Dim i As Integer
Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count
If iAreaCount <= 1 Then
MsgBox "The selection contains " & Selection.Columns.Count & " columns."
Else
For i = 1 To iAreaCount
MsgBox "Area " & i & " of the selection contains " & _
Selection.Areas(i).Columns.Count & " columns."
Next i
End If
End Sub

What I want to say here is like some kind of add-on on @Suciu Lucian's answer.
The weird situation I ran into is that when I apply the solution of @Suciu Lucian in my file, it works in Chrome but not in Safari (and did not try in Firefox). After I studied the guide of styling table border published by w3.org, I found something alternative:
table.myTable{
border-spacing: 0;
}
table.myTable td{
border-bottom:1px solid red;
}
Yes you have to style the td
instead of the tr
.
While moopasta's answer works, it doesn't appear to allow wildcards and there is another (potentially better) option. The Chromium project has some HTTP authentication documentation that is useful but incomplete.
Specifically the option that I found best is to whitelist sites that you would like to allow Chrome to pass authentication information to, you can do this by:
auth-server-whitelist
command line switch. e.g. --auth-server-whitelist="*example.com,*foobar.com,*baz"
. Downfall to this approach is that opening links from other programs will launch Chrome without the command line switch.AuthServerWhitelist
/"Authentication server whitelist" Group Policy or Local Group Policy. This seems like the most stable option but takes more work to setup. You can set this up locally, no need to have this remotely deployed.Those looking to set this up for an enterprise can likely follow the directions for using Group Policy or the Admin console to configure the AuthServerWhitelist
policy. Those looking to set this up for one machine only can also follow the Group Policy instructions:
Start > Run > gpedit.msc
Local Computer Policy > Computer Configuration > Administrative Templates
Administrative Templates
, and select Add/Remove Templates
windows\adm\en-US\chrome.adm
template via the dialogComputer Configuration > Administrative Templates > Classic Administrative Templates > Google > Google Chrome > Policies for HTTP Authentication
enable and configure Authentication server whitelist
chrome://policy
to view active policiesYou can avoid the repetition with an attribute test instead:
a/b/*[local-name()='c' or local-name()='d' or local-name()='e']
Contrary to Dimitre's antagonistic opinion, the above is not incorrect in a vacuum where the OP has not specified the interaction with namespaces. The self::
axis is namespace restrictive, local-name()
is not. If the OP's intention is to capture c|d|e
regardless of namespace (which I'd suggest is even a likely scenario given the OR nature of the problem) then it is "another answer that still has some positive votes" which is incorrect.
You can't be definitive without definition, though I'm quite happy to delete my answer as genuinely incorrect if the OP clarifies his question such that I am incorrect.
If you're using onCreateOptionsMenu, you can also add setTitle code in onCreateOptionsMenu.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
setTitle("Neue Aktivität");
return true;
}
Rails scaffolds use 422 Unprocessable Entity
for these kinds of errors. See RFC 4918 for more information.
search your code you must be referring to color in color.xml
in an xml drawable.
go and give hex code instead of referencing....
Example:
in drawable.xml
you must have called
android:fillColor="@color/blue"
change it to android:fillColor="#ffaacc"
hope it solve your problem...
Found a way to do this, simply add a querystring to load your components, like so:
@Component({
selector: 'some-component',
templateUrl: `./app/component/stuff/component.html?v=${new Date().getTime()}`,
styleUrls: [`./app/component/stuff/component.css?v=${new Date().getTime()}`]
})
This should force the client to load the server's copy of the template instead of the browser's. If you would like it to refresh only after a certain period of time you could use this ISOString instead:
new Date().toISOString() //2016-09-24T00:43:21.584Z
And substring some characters so that it will only change after an hour for example:
new Date().toISOString().substr(0,13) //2016-09-24T00
Hope this helps
Changing the background property might not be enough as the component won't look like a button anymore. You might need to re-implement the paint method as in here to get a better result:
In iOS 8.0 and above it can be done by setting the property modalPresentationStyle to UIModalPresentationOverCurrentContext
//Set property **definesPresentationContext** YES to avoid presenting over presenting-viewController's navigation bar
self.definesPresentationContext = YES; //self is presenting view controller
presentedController.view.backgroundColor = [YOUR_COLOR with alpha OR clearColor]
presentedController.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[self presentViewController:presentedController animated:YES completion:nil];
I'll just post the code to do this using the fluent API mapping.
public class User {
public int UserID { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public ICollection<UserEmail> UserEmails { get; set; }
}
public class Email {
public int EmailID { get; set; }
public string Address { get; set; }
public ICollection<UserEmail> UserEmails { get; set; }
}
public class UserEmail {
public int UserID { get; set; }
public int EmailID { get; set; }
public bool IsPrimary { get; set; }
}
On your DbContext
derived class you could do this:
public class MyContext : DbContext {
protected override void OnModelCreating(DbModelBuilder builder) {
// Primary keys
builder.Entity<User>().HasKey(q => q.UserID);
builder.Entity<Email>().HasKey(q => q.EmailID);
builder.Entity<UserEmail>().HasKey(q =>
new {
q.UserID, q.EmailID
});
// Relationships
builder.Entity<UserEmail>()
.HasRequired(t => t.Email)
.WithMany(t => t.UserEmails)
.HasForeignKey(t => t.EmailID)
builder.Entity<UserEmail>()
.HasRequired(t => t.User)
.WithMany(t => t.UserEmails)
.HasForeignKey(t => t.UserID)
}
}
It has the same effect as the accepted answer, with a different approach, which is no better nor worse.
no, it has a number of methods, info(), debug(), warn(), etc (this replaces the priority field)

There are a lot of options:
int x = 30;
if (Enumerable.Range(1,100).Contains(x))
//true
if (x >= 1 && x <= 100)
//true

Why not disecting a bare minimum authentication module?
SweetAuth
https://www.npmjs.com/package/sweet-auth
It's simple as:
app.get('/private-page', (req, res) => {
if (req.user.isAuthorized) {
// user is logged in! send the requested page
// you can access req.user.email
}
else {
// user not logged in. redirect to login page
}
})
This version builds on Robert Elliot's, but I'm not 100% sure of its efficacy.
// There are a few dependencies added by one of the Scala plugins that this cannot reach.
task downloadDependencies {
description "Pre-downloads *most* dependencies"
doLast {
configurations.getAsMap().each { name, config ->
println "Retrieving dependencies for $name"
try {
config.files
} catch (e) {
project.logger.info e.message // some cannot be resolved, silentlyish skip them
}
}
}
}
I tried putting it into configuration instead of action (by removing doLast) and it broke zinc. I worked around it, but the end result was the same with or without. So, I left it as an explicit state. It seems to work enough to reduce the dependencies that have to be downloaded later, but not eliminate them in my case. I think one of the Scala plugins adds dependencies later.
All of the javascript functions given here won't work for an xml document having unspecified white spaces between the end tag '>' and the start tag '<'. To fix them, you just need to replace the first line in the functions
var reg = /(>)(<)(\/*)/g;

var reg = /(>)\s*(<)(\/*)/g;
You will be able to get the current iteration's index
for the map
method through its 2nd parameter.
Example:
const list = [ 'h', 'e', 'l', 'l', 'o'];
list.map((currElement, index) => {
console.log("The current iteration is: " + index);
console.log("The current element is: " + currElement);
console.log("\n");
return currElement; //equivalent to list[index]
});
Output:
The current iteration is: 0 <br>The current element is: h
The current iteration is: 1 <br>The current element is: e
The current iteration is: 2 <br>The current element is: l
The current iteration is: 3 <br>The current element is: l
The current iteration is: 4 <br>The current element is: o

1) currentValue
The current element being processed in the array.2) index
The index of the current element being processed in the array.3) array

The problem was the notify filters. The program was trying to open a file that was still copying. I removed all of the notify filters except for LastWrite.
private void watch()
{
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = path;
watcher.NotifyFilter = NotifyFilters.LastWrite;
watcher.Filter = "*.*";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.EnableRaisingEvents = true;
}
Java 8 implementation (List initialized with 60
zeroes):
List<Integer> list = IntStream.of(new int[60])
.boxed()
.collect(Collectors.toList());
new int[N]
- creates an array filled with zeroes & length N boxed()
- each element boxed to an Integercollect(Collectors.toList())
- collects elements of streamThe answer is not to add a newline after writing your string. That may solve a different problem. What you are asking is how to add a newline before you start appending your string. If you want to add a newline, but only if one does not already exist, you need to find out first, by reading the file.
For example,
with open('hst.txt') as fobj:
text = fobj.read()
name = 'Bob'
with open('hst.txt', 'a') as fobj:
if not text.endswith('\n'):
fobj.write('\n')
fobj.write(name)
You might want to add the newline after name, or you may not, but in any case, it isn't the answer to your question.
since strings data types have variable length, it is by default stored as object dtype. If you want to store them as string type, you can do something like this.
df['column'] = df['column'].astype('|S80') #where the max length is set at 80 bytes,
or alternatively
df['column'] = df['column'].astype('|S') # which will by default set the length to the max len it encounters
If using Sql Server Management Studio Designer just select both rows (Shift+Click) and Set Primary Key.
At the time of writing this answer, there was no method to embed which let the user navigate inside folders and view the files without her leaving the website (the method in other answers, makes everything open in a new tab on google drive website), so I made my own tool for it. To embed a drive, paste the iframe code below in your HTML:
<iframe src="https://googledriveembedder.collegefam.com/?key=YOUR_API_KEY&folderid=FOLDER_ID_WHIHCH_IS_PUBLICLY_VIEWABLE" style="border:none;" width="100%"></iframe>
In the above code, you need to have your own API key and the folder ID. You can set the height as per your wish.
To get the API key:
1.) Go to https://console.developers.google.com/ Create a new project.
2.) From the menu button, go to 'APIs and Services' --> 'Dashboard' --> Click on 'Enable APIs and Services'.
3.) Search for 'Google Drive API', enable it. Then go to "credentials' tab, and create credentials. Keep your API key unrestricted.
4.) Copy the newly generated API key.
To get the folder ID:
1.)Go to the google drive folder you want to embed (for example, drive.google.com/drive/u/0/folders/1v7cGug_e3lNT0YjhvtYrwKV7dGY-Nyh5u [this is not a real folder]) Ensure that the folder is publicly shared and visible to anyone.
2.) Copy the part after 'folders/', this is your folder ID.
Now put both the API key and folder id in the above code and embed.
Note: To hide the download button for files, add '&allowdl=no' at the end of the iframe's src URL.
I made the widget keeping mobile users in mind, however it suits both mobile and desktop. If you run into issues, leave a comment here. I have attached some screenshots of the content of the iframe here.
What you are possibly looking for is map()
. You can "convert" the objects in a stream to another by mapping this way:
...
.map(userMeal -> new UserMealExceed(...))
...
Alternative syntax using the -Not
operator and depending on your preference for readability:
if( -Not (Test-Path -Path $TARGETDIR ) )
{
New-Item -ItemType directory -Path $TARGETDIR
}
This is what i used:
var culture = System.Globalization.CultureInfo.CurrentCulture;
and it's working :)
As mentioned, Function.bind()
lets you specify the context that the function will execute in (that is, it lets you pass in what object the this
keyword will resolve to in the body of the function.
A couple of analogous toolkit API methods that perform a similar service:
Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.
Based off of @Mike Sherrill Cat Recall's answer, this is what worked for me:
ALTER TABLE "Children"
DROP CONSTRAINT "Children_parentId_fkey",
ADD CONSTRAINT "Children_parentId_fkey"
FOREIGN KEY ("parentId")
REFERENCES "Parent"(id)
ON DELETE CASCADE;
You simply do it like
var data = {
"0": "1",
"1": "2",
"2": "3",
"3": "4"
};
var arr = [];
for (var prop in data) {
arr.push(data[prop]);
}
console.log(arr);
I have found the designer "update from database" can only handle small changes. If you have deleted tables, changed foreign keys or (gasp) changed the signature of a stored procedure with a function mapping, you will eventually get to such a messed up state you will have to either delete all the entities and "add from database" or simply delete the edmx resource and start over.
If you have a button in asp.net design page like "Default.asp" and you want to create CSS file and specified attributes for a button,labels or other controller. Then first of all create a css page
now you have a css page now write these code in your css page(StyleSheet.css)
StyleSheet.css
.mybtnstyle
{
border:1px solid Red;
background-color:Red;
border-style:groove;
border-top:5px;
outline-style:dotted;
}

{

If you only want to see the keys/values from your map and like using boost, you can use the boost adaptors with the range based loops:
for (const auto& value : myMap | boost::adaptors::map_values)
{
std::cout << value << std::endl;
}
there is an equivalent boost::adaptors::key_values

In the opening tag of your form, set an action attribute like so:
<form id="contactForm" action="#">
Basically Spring is a framework for dependency-injection which is a pattern that allows building very decoupled systems.
For example, suppose you need to list the users of the system and thus declare an interface called UserLister
:
public interface UserLister {
List<User> getUsers();
}
And maybe an implementation accessing a database to get all the users:
public class UserListerDB implements UserLister {
public List<User> getUsers() {
// DB access code here
}
}
In your view you'll need to access an instance (just an example, remember):
public class SomeView {
private UserLister userLister;
public void render() {
List<User> users = userLister.getUsers();
view.render(users);
}
}
Note that the code above hasn't initialized the variable userLister
. What should we do? If I explicitly instantiate the object like this:
UserLister userLister = new UserListerDB();
...I'd couple the view with my implementation of the class that access the DB. What if I want to switch from the DB implementation to another that gets the user list from a comma-separated file (remember, it's an example)? In that case, I would go to my code again and change the above line to:
UserLister userLister = new UserListerCommaSeparatedFile();
This has no problem with a small program like this but... What happens in a program that has hundreds of views and a similar number of business classes? The maintenance becomes a nightmare!
What Spring does is to wire the classes up by using an XML file or annotations, this way all the objects are instantiated and initialized by Spring and injected in the right places (Servlets, Web Frameworks, Business classes, DAOs, etc, etc, etc...).
Going back to the example in Spring we just need to have a setter for the userLister
field and have either an XML file like this:
<bean id="userLister" class="UserListerDB" />
<bean class="SomeView">
<property name="userLister" ref="userLister" />
</bean>
or more simply annotate the filed in our view class with @Inject
:
@Inject
private UserLister userLister;
This way when the view is created it magically will have a UserLister
ready to work.
List<User> users = userLister.getUsers(); // This will actually work
// without adding any line of code
It is great! Isn't it?
UserLister
interface? Just change the XML.UserLister
implementation ready? Program a temporal mock implementation of UserLister
and ease the development of the view.There are some other options for Dependency Injection around there, what in my opinion has made Spring so famous besides its simplicity, elegance and stability is that the guys of SpringSource have programmed many many POJOs that help to integrate Spring with many other common frameworks without being intrusive in your application. Also, Spring has several good subprojects like Spring MVC, Spring WebFlow, Spring Security and again a loooong list of etceteras.
Hope this helps. Anyway, I encourage you to read Martin Fowler's article about Dependency Injection and Inversion of Control because he does it better than me. After understanding the basics take a look at Spring Documentation, in my opinion, it is used to be the best Spring book ever.
Here is a short and fast in-memory solution that I came up with utilizing the Table Valued Constructors introduced in SQL Server 2008:
It will return 1,000,000 rows, however you can either add/remove CROSS JOINs, or use TOP clause to modify this.
;WITH v AS (SELECT * FROM (VALUES(0),(0),(0),(0),(0),(0),(0),(0),(0),(0)) v(z))
SELECT N FROM (SELECT ROW_NUMBER() OVER (ORDER BY v1.z)-1 N FROM v v1
CROSS JOIN v v2 CROSS JOIN v v3 CROSS JOIN v v4 CROSS JOIN v v5 CROSS JOIN v v6) Nums
Note that this could be quickly calculated on the fly, or (even better) stored in a permanent table (just add an INTO
clause after the SELECT N
segment) with a primary key on the N
field for improved efficiency.
Use a for
loop to iterate through your array. For each string, create a new option
element, assign the string as its innerHTML
and value
, and then append it to the select
element.
var cuisines = ["Chinese","Indian"];
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
var opt = document.createElement('option');
opt.innerHTML = cuisines[i];
opt.value = cuisines[i];
sel.appendChild(opt);
}
UPDATE: Using createDocumentFragment
and forEach
If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment
acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild
operation so that the DOM only updates once, instead of n
times.
var cuisines = ["Chinese","Indian"];
var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();
cuisines.forEach(function(cuisine, index) {
var opt = document.createElement('option');
opt.innerHTML = cuisine;
opt.value = cuisine;
fragment.appendChild(opt);
});
sel.appendChild(fragment);

It's fairly easy using the New-SelfSignedCertificate command in Powershell. Open powershell and run these 3 commands.
1) Create certificate:
$cert = New-SelfSignedCertificate -DnsName www.yourwebsite.com -Type CodeSigning -CertStoreLocation Cert:\CurrentUser\My2) set the password for it:
$CertPassword = ConvertTo-SecureString -String "my_passowrd" -Force –AsPlainText3) Export it:
Export-PfxCertificate -Cert "cert:\CurrentUser\My\$($cert.Thumbprint)" -FilePath "d:\selfsigncert.pfx" -Password $CertPassword
Your certificate selfsigncert.pfx will be located @ D:/
Optional step: You would also require to add certificate password to system environment variables. do so by entering below in cmd: setx CSC_KEY_PASSWORD "my_password"
See the git-pull man page:
git pull [options] [<repository> [<refspec>...]]
and in the examples section:
Merge into the current branch the remote branch next:
$ git pull origin next
So I imagine you want to do something like:
git pull origin dev
To set it up so that it does this by default while you're on the dev branch:
git branch --set-upstream-to dev origin/dev
Or use JodaTime:
DateTime lastWeek = new DateTime().minusDays(7);
On the phone
Have you enabled Developer Mode?
Have you enabled USB debugging within the Developer Tools menu in settings (this menu doesn't appear unless you've enabled Developer Mode)
Do you have a good and securely connected USB cable?
In Android Studio
In Edit Run/Debug Configurations, do you have "Target: USB Device"?
It may help to download the latest version of the USB driver for that particular phone.
It's also helpful to know whether your phone appears as a recognised device at the operating system level. And when in doubt, reboot everything you can think of.
You have forgotten to mark the getProducts return type as an array. In your getProducts it says that it will return a single product. So change it to this:
public getProducts(): Observable<Product[]> {
return this.http.get<Product[]>(`api/products/v1/`);
}
Try this in MVC 4.0
@Html.TextBoxFor(m => m.YourDate, "{0:dd/MM/yyyy}", new { @class = "datefield form-control", @placeholder = "Enter start date..." })
You can use filter() to do that:
var tableRow = $("td").filter(function() {
return $(this).text() == "foo";
}).closest("tr");

With router
:
import { useRouter } from 'next/router'
const Index = () => {
const router = useRouter()
const {id} = router.query
return(<div>{id}</div>)
}
With getInitialProps
:
const Index = ({id}) => {
return(<div>{id}</div>)
}
Index.getInitialProps = async ({ query }) => {
const {id} = query
return {id}
}

If a
is a prime then the while x:
in your code will run forever, since x
will remain True
.
So why is that while
there?
I think you wanted to end the for loop when you found a factor, but didn't know how, so you added that while since it has a condition. So here is how you do it:
def is_prime(a):
x = True
for i in range(2, a):
if a%i == 0:
x = False
break # ends the for loop
# no else block because it does nothing ...
if x:
print "prime"
else:
print "not prime"

If I understand correctly, you're looking for a multi-line representation, for readability? You want something like a here-string in other languages. Javascript can come close with this:
var x =
"<div> \
<span> \
<p> \
some text \
</p> \
</div>";
You can change the index as explained already using set_index
.
You don't need to manually swap rows with columns, there is a transpose (data.T
) method in pandas that does it for you:
> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
['ABERFELDIE', 534000, 600000]],
columns=['Locality', 2005, 2006])
> newdf = df.set_index('Locality').T
> newdf
Locality ABBOTSFORD ABERFELDIE
2005 427000 534000
2006 448000 600000
then you can fetch the dataframe column values and transform them to a list:
> newdf['ABBOTSFORD'].values.tolist()
[427000, 448000]
Actually, you just have to add the shell=True
argument:
subprocess.call("sleep.sh", shell=True)
But beware -
Warning Invoking the system shell with shell=True can be a security hazard if combined with untrusted input. See the warning under Frequently Used Arguments for details.

I would like to answer your question, as there are various methods - here I’ll talk about the code that is widely used.
So, for hiding the sheet:
Sub try()
Worksheets("Sheet1").Visible = xlSheetHidden
End Sub
There are other methods also if you want to learn all Methods Click here
<?php
$file = 'count.txt';
//get the number from the file
$uniq = file_get_contents($file);
//add +1
$id = $uniq + 1 ;
// add that new value to text file again for next use
file_put_contents($file, $id);
// your unique id ready
echo $id;
?>
i hope this will work fine. i use the same technique in my website.
When you click your button you can have it call:
super.onBackPressed();
If you already have a unique or primary key, the other answers with either INSERT INTO ... ON DUPLICATE KEY UPDATE ...
or REPLACE INTO ...
should work fine (note that replace into deletes if exists and then inserts - thus does not partially update existing values).
But if you have the values for some_column_id
and some_type
, the combination of which are known to be unique. And you want to update some_value
if exists, or insert if not exists. And you want to do it in just one query (to avoid using a transaction). This might be a solution:
INSERT INTO my_table (id, some_column_id, some_type, some_value)
SELECT t.id, t.some_column_id, t.some_type, t.some_value
FROM (
SELECT id, some_column_id, some_type, some_value
FROM my_table
WHERE some_column_id = ? AND some_type = ?
UNION ALL
SELECT s.id, s.some_column_id, s.some_type, s.some_value
FROM (SELECT NULL AS id, ? AS some_column_id, ? AS some_type, ? AS some_value) AS s
) AS t
LIMIT 1
ON DUPLICATE KEY UPDATE
some_value = ?
Basically, the query executes this way (less complicated than it may look):
WHERE
clause match.s
), where the column values are explicitly given (s.id is NULL, so it will generate a new auto-increment identifier).s
is discarded (due to LIMIT 1 on table t
), and it will always trigger an ON DUPLICATE KEY
which will UPDATE
the some_value
column.s
).Note: Every table in a relational database should have at least a primary auto-increment id
column. If you don't have this, add it, even when you don't need it at first sight. It is definitely needed for this "trick".
I hope it still not too late to share my solution. Before that, you can follow the tutorial as stated in Android Developer documentation. To achieve this, you need to use Cluster Manager with defaultRenderer
.
Create an object that implements ClusterItem
public class SampleJob implements ClusterItem {
private double latitude;
private double longitude;
//Create constructor, getter and setter here
@Override
public LatLng getPosition() {
return new LatLng(latitude, longitude);
}
Create a default renderer class. This is the class that do all the job (inflating custom marker/cluster with your own style). I am using Universal image loader to do the downloading and caching the image.
public class JobRenderer extends DefaultClusterRenderer< SampleJob > {
private final IconGenerator iconGenerator;
private final IconGenerator clusterIconGenerator;
private final ImageView imageView;
private final ImageView clusterImageView;
private final int markerWidth;
private final int markerHeight;
private final String TAG = "ClusterRenderer";
private DisplayImageOptions options;
public JobRenderer(Context context, GoogleMap map, ClusterManager<SampleJob> clusterManager) {
super(context, map, clusterManager);
// initialize cluster icon generator
clusterIconGenerator = new IconGenerator(context.getApplicationContext());
View clusterView = LayoutInflater.from(context).inflate(R.layout.multi_profile, null);
clusterIconGenerator.setContentView(clusterView);
clusterImageView = (ImageView) clusterView.findViewById(R.id.image);
// initialize cluster item icon generator
iconGenerator = new IconGenerator(context.getApplicationContext());
imageView = new ImageView(context.getApplicationContext());
markerWidth = (int) context.getResources().getDimension(R.dimen.custom_profile_image);
markerHeight = (int) context.getResources().getDimension(R.dimen.custom_profile_image);
imageView.setLayoutParams(new ViewGroup.LayoutParams(markerWidth, markerHeight));
int padding = (int) context.getResources().getDimension(R.dimen.custom_profile_padding);
imageView.setPadding(padding, padding, padding, padding);
iconGenerator.setContentView(imageView);
options = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.circle_icon_logo)
.showImageForEmptyUri(R.drawable.circle_icon_logo)
.showImageOnFail(R.drawable.circle_icon_logo)
.cacheInMemory(false)
.cacheOnDisk(true)
.considerExifParams(true)
.bitmapConfig(Bitmap.Config.RGB_565)
.build();
}
@Override
protected void onBeforeClusterItemRendered(SampleJob job, MarkerOptions markerOptions) {
ImageLoader.getInstance().displayImage(job.getJobImageURL(), imageView, options);
Bitmap icon = iconGenerator.makeIcon(job.getName());
markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon)).title(job.getName());
}
@Override
protected void onBeforeClusterRendered(Cluster<SampleJob> cluster, MarkerOptions markerOptions) {
Iterator<Job> iterator = cluster.getItems().iterator();
ImageLoader.getInstance().displayImage(iterator.next().getJobImageURL(), clusterImageView, options);
Bitmap icon = clusterIconGenerator.makeIcon(iterator.next().getName());
markerOptions.icon(BitmapDescriptorFactory.fromBitmap(icon));
}
@Override
protected boolean shouldRenderAsCluster(Cluster cluster) {
return cluster.getSize() > 1;
}
Apply cluster manager in your activity/fragment class.
public class SampleActivity extends AppCompatActivity implements OnMapReadyCallback {
private ClusterManager<SampleJob> mClusterManager;
private GoogleMap mMap;
private ArrayList<SampleJob> jobs = new ArrayList<SampleJob>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_landing);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.getUiSettings().setMapToolbarEnabled(true);
mClusterManager = new ClusterManager<SampleJob>(this, mMap);
mClusterManager.setRenderer(new JobRenderer(this, mMap, mClusterManager));
mMap.setOnCameraChangeListener(mClusterManager);
mMap.setOnMarkerClickListener(mClusterManager);
//Assume that we already have arraylist of jobs
for(final SampleJob job: jobs){
mClusterManager.addItem(job);
}
mClusterManager.cluster();
}

Per the Javadoc:
Returns the value of a request parameter as a String, or null if the parameter does not exist.
Do note that it is possible to submit an empty parameter - such that the parameter exists, but has no value. For example, I could include &log=&somethingElse
into the URL to enable logging, without needing to specify &log=true
. In this case, the value will be an empty String (""
).
It's very easy:
numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
if numb == lines[0]:
print lines

Follow these steps:
1. Generate an APNs Auth Key
Open the APNs Auth Key page in your Developer Center and click the + button to create a new APNs Auth Key.
In the next page, select Apple Push Notification Authentication Key (Sandbox & Production) and click Continue at the bottom of the page.
Apple will then generate a .p8
key file containing your APNs Auth Key.
Download the .p8
key file to your computer and save it for later. Also, be sure to write down the Key ID somewhere, as you'll need it later when connecting to APNs.
2. Send Push Notifications
Ref: APNS (Configure push notifications)
Important: Save a back up of your key in a secure place. It will not be presented again and cannot be retrieved later.
Just use the float style. Put your google map iframe in a div class, and the paragraph in another div class, then apply the following CSS styles to those div classes(don't forget to clear the blocks after float effect, to not make the blocks trouble below them):
css
.google_map{
width:55%;
margin-right:2%;
float: left;
}
.google_map iframe{
width:100%;
}
.paragraph {
width:42%;
float: left;
}
.clearfix{
clear:both
}
html
<div class="google_map">
<iframe></iframe>
</div>
<div class="paragraph">
<p></p>
</div>
<div class="clearfix"></div>
anyone who says activex is less secure then NPAPI is crazy. They both allow the exact same access. Yes I've written both. The only reason people think activeX is insecure is because 10+ years ago IE had default settings that allowed a remote site to auto download the plugin.
Do a regex "Search" for \t
(backslash-t, a tab), and replace with four spaces.
Either the main menu, or lower-right status-bar spacing menu does the same thing, with less work.
You mentioned using json2.js to stringify your data, but the POSTed data appears to be URLEncoded JSON You may have already seen it, but this post about the invalid JSON primitive covers why the JSON is being URLEncoded.
I'd advise against passing a raw, manually-serialized JSON string into your method. ASP.NET is going to automatically JSON deserialize the request's POST data, so if you're manually serializing and sending a JSON string to ASP.NET, you'll actually end up having to JSON serialize your JSON serialized string.
I'd suggest something more along these lines:
var markers = [{ "position": "128.3657142857143", "markerPosition": "7" },
{ "position": "235.1944023323615", "markerPosition": "19" },
{ "position": "42.5978231292517", "markerPosition": "-3" }];
$.ajax({
type: "POST",
url: "/webservices/PodcastService.asmx/CreateMarkers",
// The key needs to match your method's input parameter (case-sensitive).
data: JSON.stringify({ Markers: markers }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data){alert(data);},
error: function(errMsg) {
alert(errMsg);
}
});
The key to avoiding the invalid JSON primitive issue is to pass jQuery a JSON string for the data
parameter, not a JavaScript object, so that jQuery doesn't attempt to URLEncode your data.
On the server-side, match your method's input parameters to the shape of the data you're passing in:
public class Marker
{
public decimal position { get; set; }
public int markerPosition { get; set; }
}
[WebMethod]
public string CreateMarkers(List<Marker> Markers)
{
return "Received " + Markers.Count + " markers.";
}
You can also accept an array, like Marker[] Markers
, if you prefer. The deserializer that ASMX ScriptServices uses (JavaScriptSerializer) is pretty flexible, and will do what it can to convert your input data into the server-side type you specify.
Here is the proper documentation for the jQueryUI widget. There isn't a built-in parameter for limiting max results, but you can accomplish it easily:
$("#auto").autocomplete({
source: function(request, response) {
var results = $.ui.autocomplete.filter(myarray, request.term);
response(results.slice(0, 10));
}
});
You can supply a function to the source
parameter and then call slice
on the filtered array.
Here's a working example: http://jsfiddle.net/andrewwhitaker/vqwBP/
This is a follow up to my original question to help out others with the same problem. If you need to filter by an attribute, rather than manually looking up the id you can use the following code to retrieve all the id, value pairs for an attribute. The data is returned as an array with the attribute name as the key.
function getAttributeOptions($attributeName) {
$product = Mage::getModel('catalog/product');
$collection = Mage::getResourceModel('eav/entity_attribute_collection')
->setEntityTypeFilter($product->getResource()->getTypeId())
->addFieldToFilter('attribute_code', $attributeName);
$_attribute = $collection->getFirstItem()->setEntity($product->getResource());
$attribute_options = $_attribute->getSource()->getAllOptions(false);
foreach($attribute_options as $val) {
$attrList[$val['label']] = $val['value'];
}
return $attrList;
}
Here is a function you can use to get products by their attribute set id. Retrieved using the previous function.
function getProductsByAttributeSetId($attributeSetId) {
$products = Mage::getModel('catalog/product')->getCollection();
$products->addAttributeToFilter('attribute_set_id',$attributeSetId);
$products->addAttributeToSelect('*');
$products->load();
foreach($products as $val) {
$productsArray[] = $val->getData();
}
return $productsArray;
}
As I just came across this topic I wanted to share the reason and solution why I got the message "invalid or corrupt jarfile":
I had updated the version of the "maven-jar-plugin" in my pom.xml from 2.1 to 3.1.2. Everything still went fine and a jar file was built. But somehow it obviously wouldn't run anymore.
As soon as i set the "maven-jar-plugin" version back to 2.1 again, the problem was gone.
For Windows, here's a link to an example batch file that only allows changes to the log message (not other properties):
http://ayria.livejournal.com/33438.html
Basically copy the code below into a text file and name it pre-revprop-change.bat
and save it in the \hooks
subdirectory for your repository.

Addition to @BalusC 's answer. You also need to set width of headers. In my case, below css can only apply to my table's column width.
.myTable td:nth-child(1),.myTable th:nth-child(1) {
width: 20px;
}
# Let's add key:value to a dictionary, the functional way
# Create your dictionary class
class my_dictionary(dict):
# __init__ function
def __init__(self):
self = dict()
# Function to add key:value
def add(self, key, value):
self[key] = value
# Main Function
dict_obj = my_dictionary()
limit = int(input("Enter the no of key value pair in a dictionary"))
c=0
while c < limit :
dict_obj.key = input("Enter the key: ")
dict_obj.value = input("Enter the value: ")
dict_obj.add(dict_obj.key, dict_obj.value)
c += 1
print(dict_obj)
If the FileInfo class has more than one ancestor class then you should definitely call all of their __init__() functions. You should also do the same for the __del__() function, which is a destructor.
Do you really want to style the <div>
? Or do you want to style the <input type="button">
? You should use the correct selector if you want the latter:
input[type=button] {
color:#08233e;
font:2.4em Futura, ‘Century Gothic’, AppleGothic, sans-serif;
font-size:70%;
/* ... other rules ... */
cursor:pointer;
}
input[type=button]:hover {
background-color:rgba(255,204,0,0.8);
}

Here's a quick overview that explains the different build targets.
From my own experience, if you're looking to build a project that will run on both x86 and x64 platforms, and you don't have any specific x64 optimizations, I'd change the build to specifically say "x86."
The reason for this is sometimes you can get some DLL files that collide or some code that winds up crashing WoW in the x64 environment. By specifically specifying x86, the x64 OS will treat the application as a pure x86 application and make sure everything runs smoothly.
Here is a solution which sorts the properties alphabetically and prints them all together with their values:
public void logProperties() throws IllegalArgumentException, IllegalAccessException {
Class<?> aClass = this.getClass();
Field[] declaredFields = aClass.getDeclaredFields();
Map<String, String> logEntries = new HashMap<>();
for (Field field : declaredFields) {
field.setAccessible(true);
Object[] arguments = new Object[]{
field.getName(),
field.getType().getSimpleName(),
String.valueOf(field.get(this))
};
String template = "- Property: {0} (Type: {1}, Value: {2})";
String logMessage = System.getProperty("line.separator")
+ MessageFormat.format(template, arguments);
logEntries.put(field.getName(), logMessage);
}
SortedSet<String> sortedLog = new TreeSet<>(logEntries.keySet());
StringBuilder sb = new StringBuilder("Class properties:");
Iterator<String> it = sortedLog.iterator();
while (it.hasNext()) {
String key = it.next();
sb.append(logEntries.get(key));
}
System.out.println(sb.toString());
}

If you want to set default value in terms of database, just set @Column( columnDefinition = "int default 1")
But if what you intend is to set a default value in your java app you can set it on your class attribute like this: private Integer attribute = 1;
always Until you fully understand the differences and implications of using the ==
and ===
operators, use the ===
operator since it will save you from obscure (non-obvious) bugs and WTFs. The "regular" ==
operator can have very unexpected results due to the type-coercion internally, so using ===
is always the recommended approach.
For insight into this, and other "good vs. bad" parts of Javascript read up on Mr. Douglas Crockford and his work. There's a great Google Tech Talk where he summarizes lots of good info: http://www.youtube.com/watch?v=hQVTIJBZook
Update:
The You Don't Know JS series by Kyle Simpson is excellent (and free to read online). The series goes into the commonly misunderstood areas of the language and explains the "bad parts" that Crockford suggests you avoid. By understanding them you can make proper use of them and avoid the pitfalls.
The "Up & Going" book includes a section on Equality, with this specific summary of when to use the loose (==
) vs strict (===
) operators:
To boil down a whole lot of details to a few simple takeaways, and help you know whether to use
==
or===
in various situations, here are my simple rules:
- If either value (aka side) in a comparison could be the
true
orfalse
value, avoid==
and use===
.- If either value in a comparison could be of these specific values (
0
,""
, or[]
-- empty array), avoid==
and use===
.- In all other cases, you're safe to use
==
. Not only is it safe, but in many cases it simplifies your code in a way that improves readability.
I still recommend Crockford's talk for developers who don't want to invest the time to really understand Javascript—it's good advice for a developer who only occasionally works in Javascript.
If you want to get the form data directly from Http request, without any model bindings or FormCollection
you can use this:
[HttpPost]
public ActionResult SubmitAction() {
// This will return an string array of all keys in the form.
// NOTE: you specify the keys in form by the name attributes e.g:
// <input name="this is the key" value="some value" type="test" />
var keys = Request.Form.AllKeys;
// This will return the value for the keys.
var value1 = Request.Form.Get(keys[0]);
var value2 = Request.Form.Get(keys[1]);
}
For Jackson versions < 2.0 use this annotation on the class being serialized:
@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)
You can fix this issue by deleting browser cookie from the begining of time. I have tried this and it is working fine for me.
To delete only cookies:
I work on 60-70% zoom vue and my dropdown are unreadable so I made this simple code to overcome the issue
Note that I selected first all my dropdown lsts (CTRL+mouse click), went on formula tab, clicked "define name" and called them "ProduktSelection"
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim KeyCells As Range
Set KeyCells = Range("ProduktSelection")
If Not Application.Intersect(KeyCells, Range(Target.Address)) _
Is Nothing Then
ActiveWindow.Zoom = 100
End If
End Sub
I then have another sub
Private Sub Worksheet_Change(ByVal Target As Range)
where I come back to 65% when value is changed.
double
supports Infinity
double inf = Double.POSITIVE_INFINITY;
System.out.println(inf + 5);
System.out.println(inf - inf); // same as Double.NaN
System.out.println(inf * -1); // same as Double.NEGATIVE_INFINITY
prints
Infinity
NaN
-Infinity
note: Infinity - Infinity
is Not A Number.
Here's another JavaScript solution. Works very good and very fast.

Tested on Chrome, FF, IE on Windows and Mac.
I think you misunderstood the concept of session, session is a server side per-user-data-store which allows you to save user data on the server side.
thus, you have 2 options, resort to use cookies, which will give the illusion of session(but not quite the same), you can access cookies very simply by document.cookie .
but, if you want your server be aware of the session, you need to use some sort of server request probably the best way is to use AJAX to do this.
I would recommend you to re-read the definition of sessions.
In Eclipse v4.7 (Oxygen):
Window menu ? Editor ? Toggle Word Wrap (Shift+Alt+Y)
For bitwise |
and Logicall ||
OR
bitwise &
and logicall &&
it means if( a>b | a==0)
in this first left a>b
will be evaluated and then a==0
will be evaluated then |
operation will be done
but in|| if a>b
then if wont check for next RHS
Similarly for & and &&
if(A>0 & B>0)
it will evalue LHS and then RHS then do bitwise & but
in(A>0 && B>0)
if(A>0)
is false
(LHS) it will directly return false;
brew switch to python3 by default, so if you want to still set python2 as default bin python, running:
brew unlink python && brew link python2 --force
You can also use the tag, this works in divs and everything else:
<center><form></form></center>
This link will help you with the tag:
Just set DataGridView.AutoGenerateColumns = false
;
You need click on the arrow on top right corner (in datagridview
) to add columns, and in DataPropertyName
you need to put a name of your property in your class.
Then, after you defined your columns in datagridview
, you can set datagridview.datasource = myClassViewModel
.
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;
....
this.environment.getActiveProfiles();
Relatively straightforward solution:
From the first character you want to copy, hold Shift down and go all the way to the end.
Press Ctrl+K, which cuts the text from the file.
Press Ctrl+X, and then N to not save any changes.
Paste the cut text anywhere you want.
Alternatively, if your text fits into the screen, you can simply use mouse to select and it automatically copies it to clipboard.
Starting with version 3.5.0 of Mockito and using the InlineMockMaker
, you can now mock object constructions:
try (MockedConstruction mocked = mockConstruction(A.class)) {
A a = new A();
when(a.check()).thenReturn("bar");
}
Inside the try-with-resources
construct all object constructions are returning a mock.
I think what you want to do is add a new item to your list, so you have change the line newinv=inventory+str(add)
with this one:
newinv = inventory.append(add)
What you are doing now is trying to concatenate a list with a string which is an invalid operation in Python.
However I think what you want is to add and delete items from a list, in that case your if/else block should be:
if selection=="use":
print(inventory)
remove=input("What do you want to use? ")
inventory.remove(remove)
print(inventory)
elif selection=="pickup":
print(inventory)
add=input("What do you want to pickup? ")
inventory.append(add)
print(inventory)
You don't need to build a new inventory list every time you add a new item.
Do git status
, this will show you what files have changed. Since you stated that you don't want to keep the changes you can do git checkout -- <file name>
or git reset --hard
to get rid of the changes.
For the most part, git will tell you what to do about changes. For example, your error message said to git stash
your changes. This would be if you wanted to keep them. After pulling, you would then do git stash pop
and your changes would be reapplied.
git status
also has how to get rid of changes depending on if the file is staged for commit or not.
Thanks for the replies.
What I did was,
1. I install meinberg ntp software application on windows 7 pc. (softros ntp server is also possible.)
2. change raspberry pi ntp.conf file (for auto update date and time)
server xxx.xxx.xxx.xxx iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst
3. If you want to make sure that date and time update at startup run this python script in rpi,
import os
try:
client = ntplib.NTPClient()
response = client.request('xxx.xxx.xxx.xxx', version=4)
print "===================================="
print "Offset : "+str(response.offset)
print "Version : "+str(response.version)
print "Date Time : "+str(ctime(response.tx_time))
print "Leap : "+str(ntplib.leap_to_text(response.leap))
print "Root Delay : "+str(response.root_delay)
print "Ref Id : "+str(ntplib.ref_id_to_text(response.ref_id))
os.system("sudo date -s '"+str(ctime(response.tx_time))+"'")
print "===================================="
except:
os.system("sudo date")
print "NTP Server Down Date Time NOT Set At The Startup"
pass
I found more info in raspberry pi forum.
