payton109’s answer is correct if you’re in the default US-EAST-1 region. If your bucket is in a different region, use a slightly different URL:
https://s3-<region>.amazonaws.com/your.domain.com/some/asset
Where <region>
is the bucket location name. For example, if your bucket is in the us-west-2
(Oregon) region, you can do this:
https://s3-us-west-2.amazonaws.com/your.domain.com/some/asset
Try this [reverse order traversal]:
var childs = document.getElementById('parent').childNodes;
var len = childs.length;
if(len --) do {
console.log('node: ', childs[len]);
} while(len --);
OR [in order traversal]
var childs = document.getElementById('parent').childNodes;
var len = childs.length, i = -1;
if(++i < len) do {
console.log('node: ', childs[i]);
} while(++i < len);
I to use this type of declaration:
const identity: { <T>(arg: T): T } = (arg) => arg;
It allows defining additional props to your function if you ever need to and in some cases, it helps keeping the function body cleaner from the generic definition.
If you don't need the additional props (namespace sort of thing), it can be simplified to:
const identity: <T>(arg: T) => T = (arg) => arg;
You can use PyVirtualDisplay (a Python wrapper for Xvfb) to run headless WebDriver tests.
#!/usr/bin/env python
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(800, 600))
display.start()
# now Firefox will run in a virtual display.
# you will not see the browser.
browser = webdriver.Firefox()
browser.get('http://www.google.com')
print browser.title
browser.quit()
display.stop()
You can also use xvfbwrapper, which is a similar module (but has no external dependencies):
from xvfbwrapper import Xvfb
vdisplay = Xvfb()
vdisplay.start()
# launch stuff inside virtual display here
vdisplay.stop()
or better yet, use it as a context manager:
from xvfbwrapper import Xvfb
with Xvfb() as xvfb:
# launch stuff inside virtual display here.
# It starts/stops in this code block.
Your second way is correct.
def foo(opts: dict = {}):
pass
print(foo.__annotations__)
this outputs
{'opts': <class 'dict'>}
It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.
I strongly advise against using mutable keyword arguments. More information here.

Add a class as Public and use it very easily like convertToInt32()
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>

public static class Common
{
public static double ConvertToDouble(string Value) {
if (Value == null) {
return 0;
}
else {
double OutVal;
double.TryParse(Value, out OutVal);
if (double.IsNaN(OutVal) || double.IsInfinity(OutVal)) {
return 0;
}
return OutVal;
}
}
}
Then Call The Function
double DirectExpense = Common.ConvertToDouble(dr["DrAmount"].ToString());
I would go with unset because it might give the garbage collector a better hint so that the memory can be available again sooner. Be careful that any things the object points to either have other references or get unset first or you really will have to wait on the garbage collector since there would then be no handles to them.
As @hanmari mentioned in his comment. when inserting into a postgres tables, the on conflict (..) do nothing is the best code to use for not inserting duplicate data.:
query = "INSERT INTO db_table_name(column_name)
VALUES(%s) ON CONFLICT (column_name) DO NOTHING;"
The ON CONFLICT line of code will allow the insert statement to still insert rows of data. The query and values code is an example of inserted date from a Excel into a postgres db table. I have constraints added to a postgres table I use to make sure the ID field is unique. Instead of running a delete on rows of data that is the same, I add a line of sql code that renumbers the ID column starting at 1. Example:
q = 'ALTER id_column serial RESTART WITH 1'
If my data has an ID field, I do not use this as the primary ID/serial ID, I create a ID column and I set it to serial. I hope this information is helpful to everyone. *I have no college degree in software development/coding. Everything I know in coding, I study on my own.
For builtin JS types you can use:
function getTypeName(val) {
return {}.toString.call(val).slice(8, -1);
}
Here we use 'toString' method from 'Object' class which works different than the same method of another types.
Examples:
// Primitives
getTypeName(42); // "Number"
getTypeName("hi"); // "String"
getTypeName(true); // "Boolean"
getTypeName(Symbol('s'))// "Symbol"
getTypeName(null); // "Null"
getTypeName(undefined); // "Undefined"
// Non-primitives
getTypeName({}); // "Object"
getTypeName([]); // "Array"
getTypeName(new Date); // "Date"
getTypeName(function() {}); // "Function"
getTypeName(/a/); // "RegExp"
getTypeName(new Error); // "Error"
If you need a class name you can use:
instance.constructor.name
Examples:
({}).constructor.name // "Object"
[].constructor.name // "Array"
(new Date).constructor.name // "Date"
function MyClass() {}
let my = new MyClass();
my.constructor.name // "MyClass"
But this feature was added in ES2015.
Your @Entity
class has a String
type for its @Id
field, so it can't generate ids for you.
If you change it to an auto increment in the DB and a Long
in java, and add the @GeneratedValue
annotation:
@Id
@Column(name="U_id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long U_id;
it will handle incrementing id generation for you.
This selects all DIVs with an ID containing 'foo' and that are visible
$("div:visible[id*='foo']");
Updating to the latest version of Chrome (63.0.3239.84) via Help -> About fixed it for me.

If you want to set backgroundColor of button programmatically then this code will surly help you
Swift 3 and Swift 4
self.yourButton.backgroundColor = UIColor.red
Swift 2.3 or lower
self.yourButton.backgroundColor = UIColor.redColor()
Using RGB
self.yourButton.backgroundColor = UIColor(red: 102/255, green: 250/255, blue: 51/255, alpha: 0.5)
or you can use float values
button.backgroundColor = UIColor(red: 0.4, green: 1.0, blue: 0.2, alpha: 0.5)
In this particular example, it makes no difference. However, the {}
in ${}
are useful if you want to expand the variable foo
in the string
"${foo}bar"
since "$foobar"
would instead expand the variable identified by foobar
.
Curly braces are also unconditionally required when:
${array[42]}
${filename%.*}
(remove extension)"$8 $9 ${10} ${11}"
Doing this everywhere, instead of just in potentially ambiguous cases, can be considered good programming practice. This is both for consistency and to avoid surprises like $foo_$bar.jpg
, where it's not visually obvious that the underscore becomes part of the variable name.

<div>
<object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">

I had the same issue when updating an older project. Here's what I did to resolve it:
The projects that used Entity Framework 5 and .NET 4 were installing the Entity Framework dll version 4.4. Once I switched the .NET version to 4.5 on the project, the dll version would be 5.
My problem came from older projects being on .NET 4 and a newer project running .NET 4.5 so there were 2 dll versions of EF in my solution.
Hope this helps someone...
The exception can be caught in the async function.

and the data is invalid... a ProtocolException might be thrown */
}
catch (ProtocolException ex)

just replace the files on the folder : C:\xampp\mysql\data\mysql
with the files on : C:\xampp\mysql\backup\mysql
This is for those who want to overwrite the column cells quickly (without cutting and copying). This is the same as double-clicking the cell box but unlike double-clicking, it still works after the first try.
BONUS:
The shortcut for going to the bottom-most content (to double-check the copy) is Ctrl+⇓. To go back up you can use Ctrl+⇑ but if your top rows are frozen you'll also have to press Enter a few times.
Instead of using JTextArea.setText(String text)
, use JTextArea.append(String text)
.
Appends the given text to the end of the document. Does nothing if the model is null or the string is null or empty.
This will add text on to the end of your JTextArea
.
Another option would be to use getText()
to get the text from the JTextArea
, then manipulate the String (add or remove or change the String), then use setText(String text)
to set the text of the JTextArea
to be the new String.
Check Class.java
source code for equals()
public boolean equals(Object obj) {

Actually it is possible in JPA, although a little bit of a hack using the columnDefinition

@Column(name="Price", columnDefinition="Decimal(10,2) default '100.00'")
This error happens when the resource is busy. Check if you have any referential constraints in the query. Or even the tables that you have mentioned in the query may be busy. They might be engaged with some other job which will be definitely listed in the following query results:
SELECT * FROM V$SESSION WHERE STATUS = 'ACTIVE'
Find the SID,
SELECT * FROM V$OPEN_CURSOR WHERE SID = --the id
I think the best and clean solution is:
window.addEventListener('scroll',() => {
var x = window.scrollX;
var y = window.scrollY;
window.scrollTo(x,y);
});
And with jQuery:
$(window).on('scroll',() => {
var x = window.scrollX;
var y = window.scrollY;
window.scrollTo(x,y)
})
Those event listener should block scrolling. Just remove them to re enable scrolling

For anyone meaning to do this more reliably for different Minecraft versions, I have a Python script (adapted from parts of minecraft-launcher-lib) that does the job very nicely
Besides setting some basic variables near the top after the functions, it calls a get_classpath
that goes through for example ~/.minecraft/versions/1.16.5/1.16.5.json
, and loops over the libraries
array, checking to see if each object (within the array), is supposed to be added to the classpath (cp
variable). whether this library is added to the java classpath is governed by the should_use_library
function, deterministic based on the computer's architecture and operating system. finally, some jarfiles that are platform specific have extra things prepended to them (ex. natives-linux
in org/lwjgl/lwjgl/3.2.1/lwjgl-3.2.1-natives-linux.jar
). this extra prepended string is handled by get_natives_string
and is empty if it doesn't apply to the current library

The problem is in the Eclipse Maven support, the related question is here.
Under Eclipse, the java.home
variable is set to the JRE that was used to start Eclipse, not the build JRE. The default system JRE from C:\Program Files
doesn't include the JDK so tools.jar
is not being found.
To fix the issue you need to start Eclipse using the JRE from the JDK by adding something like this to eclipse.ini
(before -vmargs
!):
-vm
C:/<your_path_to_jdk170>/jre/bin/server/jvm.dll
Then refresh the Maven dependencies (Alt-F5) (Just refreshing the project isn't sufficient).
Use the equals
method. Why are you so worried that it's expensive?

The MaxJsonLength property cannot be unlimited, is an integer property that defaults to 102400 (100k).
You can set the MaxJsonLength
property on your web.config:
<configuration>

<webServices>
<jsonSerialization maxJsonLength="50000000"/>
</webServices>

The right answer is:
android {
....
....
sourceSets {
main.java.srcDirs += 'src/main/<YOUR DIRECTORY>'
}
}
Furthermore, if your external source directory is not under src/main
, you could use a relative path like this:
sourceSets {
main.java.srcDirs += 'src/main/../../../<YOUR DIRECTORY>'
}
Edit: as @aix suggested, a better (more fair) way to compare the speed difference:
In [1]: %timeit abs(5)
10000000 loops, best of 3: 86.5 ns per loop
In [2]: from math import fabs
In [3]: %timeit fabs(5)
10000000 loops, best of 3: 115 ns per loop
In [4]: %timeit abs(-5)
10000000 loops, best of 3: 88.3 ns per loop
In [5]: %timeit fabs(-5)
10000000 loops, best of 3: 114 ns per loop
In [6]: %timeit abs(5.0)
10000000 loops, best of 3: 92.5 ns per loop
In [7]: %timeit fabs(5.0)
10000000 loops, best of 3: 93.2 ns per loop
In [8]: %timeit abs(-5.0)
10000000 loops, best of 3: 91.8 ns per loop
In [9]: %timeit fabs(-5.0)
10000000 loops, best of 3: 91 ns per loop
So it seems abs()
only has slight speed advantage over fabs()
for integers. For floats, abs()
and fabs()
demonstrate similar speed.
In addition to what @aix has said, one more thing to consider is the speed difference:
In [1]: %timeit abs(-5)
10000000 loops, best of 3: 102 ns per loop
In [2]: import math
In [3]: %timeit math.fabs(-5)
10000000 loops, best of 3: 194 ns per loop
So abs()
is faster than math.fabs()
.
Swift Version --> Remove the object from your data array before you call
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
print("Deleted")
currentCart.remove(at: indexPath.row) //Remove element from your array
self.tableView.deleteRows(at: [indexPath], with: .automatic)
}
}
Oops. Original answer was specific to a similar question. This has been revised:
var canvas = document.getElementById("mycanvas");
var img = canvas.toDataURL("image/png");
with the value in IMG you can write it out as a new Image like so:
document.write('<img src="'+img+'"/>');
[textfield setValue:your_color forKeyPath:@"_placeholderLabel.textColor"];
Hope it helps.
Note: Apple may reject (0.01% chances) your app as we are accessing private API. I am using this in all my projects since two years, but Apple didn't ask for this.
On Linux, this is likely to be a limit on the number of file watches.
The development server uses inotify to implement hot-reloading. The inotify API allows the development server to watch files and be notified when they change.
The default inotify file watch limit varies from distribution to distribution (8192 on Fedora). The needs of the development server often exceeds this limit.
The best approach is to try increasing the file watch limit temporarily, then making that a permanent configuration change if you're happy with it. Note, though, that this changes your entire system's configuration, not just node.
To view your current limit:
sysctl fs.inotify.max_user_watches
To temporarily set a new limit:
# this limit will revert after reset
sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p
# now restart the server and see if it works
To set a permanent limit:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
For Java, from a command line:
java -version
will indicate whether it's 64-bit or not.
Output from the console on my Ubuntu box:
java version "1.6.0_12-ea"
Java(TM) SE Runtime Environment (build 1.6.0_12-ea-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.2-b01, mixed mode)
IE will indicate 64-bit versions in the About dialog, I believe.
I tried the accepted solution of using the Invoke-Expression cmdlet but it didn't work for me because my arguments had spaces on them. I tried to parse the arguments and escape the spaces but I couldn't properly make it work and also it was really a dirty work around in my opinion. So after some experimenting, my take on the problem is this:
function Invoke-Script
{
param
(
[Parameter(Mandatory = $true)]
[string]
$Script,
[Parameter(Mandatory = $false)]
[object[]]
$ArgumentList
)
$ScriptBlock = [Scriptblock]::Create((Get-Content $Script -Raw))
Invoke-Command -NoNewScope -ArgumentList $ArgumentList -ScriptBlock $ScriptBlock -Verbose
}
# example usage
Invoke-Script $scriptPath $argumentList
The only drawback of this solution is that you need to make sure that your script doesn't have a "Script" or "ArgumentList" parameter.
I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):
aptitude install debian-archive-keyring
In case it is some other keyring you need, check out
apt-cache search keyring | grep debian
My squeeze system shows all these:
debian-archive-keyring - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring - GnuPG archive keys of the Debian Edu archive
debian-keyring - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring - GnuPG archive keys for the emdebian repository

And i used in my main.xml layout like this
<Button android:id="@+id/button1"
android:layout_alignParentLeft="true"

android:textSize="7pt"
android:layout_height="wrap_content"
android:layout_width="230dip"
android:text="@string/welcomebtntitle1"

There is a correct way of uploading a file with its name with Retrofit 2, without any hack:
Define API interface:
@Multipart
@POST("uploadAttachment")
Call<MyResponse> uploadAttachment(@Part MultipartBody.Part filePart);
// You can add other parameters too
Upload file like this:
File file = // initialize file here
MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));
Call<MyResponse> call = api.uploadAttachment(filePart);
This demonstrates only file uploading, you can also add other parameters in the same method with @Part
annotation.
You import the function from outside the main instance, and don't add it to the methods block. so the context of this
is not the vm.
Either do this:
ready() {
checkAuth.call(this)
}
or add the method to your methods first (which will make Vue bind this
correctly for you) and call this method:
methods: {
checkAuth: checkAuth
},
ready() {
this.checkAuth()
}
If someone looking for a way to display decimal places even if it ends with ".00", use this:
String.Format("{0:n1}", value)
Reference:
In case anybody stumbles upon this question who cannot reload their webserver (long running console command like a queue runner) or needs to reload their .env file mid-request, i found a way to properly reload .env variables in laravel 5.
use Dotenv;
use InvalidArgumentException;
try {
Dotenv::makeMutable();
Dotenv::load(app()->environmentPath(), app()->environmentFile());
Dotenv::makeImmutable();
} catch (InvalidArgumentException $e) {

}
Tried several different commands until I came across:
source venv/Scripts/activate
This did it for me. Setup: Win 10, python 3.7, gitbash. Gitbash might be the culprit for not playing nice with other activate commands.
git status
does not always show the difference between master and origin/master even after a fetch.
If you want the combination git fetch origin && git status
to work, you need to specify the tracking information between the local branch and origin:
# git branch --set-upstream-to=origin/<branch> <branch>
For the master branch:
git branch --set-upstream-to=origin/master master
Your query should have date as
select * from table between `lowerdate` and `upperdate`
try
SELECT * FROM `objects`
WHERE (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')
I've had this happen on VS after I changed the file's line endings. Changing them back to Windows CR LF fixed the issue.
I like my bars tight and dynamic. This is for CSS 3 & HTML 5
First, setting the Width to 100px is limiting. Don't do it.
Second, setting the container's width to 100% will work ok, until were talking about it being a header/footer bar for the whole app, like a navigation or credits/copyright bar. Use right: 0;
instead for that scenario.
You are using id's (hash #container
, #left
, etc) instead of classes (.container
, .left
, etc), which is fine, unless you want to repeat your style pattern elsewhere in your code. I'd consider using classes instead.
For HTML, no need to swap order for: left, center, & right. display: inline-block;
fixes this, returning your code to something cleaner and logically in order again.
Lastly, you need to clear the floats all up so that it doesn't mess with future <div>
. You do this with the clear: both;
To summarize:
HTML:
<div class="container">
<div class="left"></div>
<div class="center"></div>
<div class="right"></div>
<div class="clear"></div>
</div>
CSS:
.container {right: 0; text-align: center;}
.container .left, .container .center, .container .right { display: inline-block; }
.container .left { float: left; }
.container .center { margin: 0 auto; }
.container .right { float: right; }
.clear { clear: both; }
Bonus point if using HAML and SASS ;)
HAML:
.container
.left
.center
.right
.clear
SASS:
.container {
right: 0;
text-align: center;
.left, .center, .right { display: inline-block; }
.left { float: left; }
.center { margin: 0 auto; }
.right { float: right; }
.clear { clear: both; }
}
Make that variable as transient.Your problem will get solved..
@Column(name="emp_name", nullable=false, length=30)
private transient String empName;
$("selectorbyclassorbyIDorbyName").click(function () {
$("selectorbyclassorbyIDorbyName").attr("disabled", true).delay(2000).attr("disabled", false);
});
select the button and by its id or text or class ... it just disables after 1st click and enables after 20 Milli sec
Works very well for post backs n place it in Master page, applies to all buttons without calling implicitly like onclientClick
The OP is trying to count the number of properties in a JSON object. This could be done with an incremented temp variable in the iterator, but he seems to want to know the count before the iteration begins. A simple function that meets the need is provided at the bottom of this page.
Here's a cut and paste of the code, which worked for me:
function countProperties(obj) {
var prop;
var propCount = 0;
for (prop in obj) {
propCount++;
}
return propCount;
}
This should work well for a JSON object. For other objects, which may derive properties from their prototype chain, you would need to add a hasOwnProperty() test.
My answer will overlap with amphibient's while adding on to it.
Your JAVA_HOME variable is fine, but you also need to append the following to your Path variable :
;%JAVA_HOME%\bin
This will allow your applications in your Windows environment to access your JDK. You should also restart your computer once you've added these environment variables before checking out if they work. In my case, even logging out and then back in didn't work : I had to completely restart.
If you want to check if the environment variables are set correctly, you can open up a command prompt and type >echo %JAVA_HOME
and >echo %Path%
to see if those variables are working correctly. While snooping around for solutions, I have also run into people claiming that they need to add quotations marks (") around the environment variables to make them work correctly ("%JAVA_HOME%"\bin
) if your JAVA_HOME path includes spaces. I thought that this was my case at first, but after doing a full restart my variables seemed to work correctly without quotation marks despite the spaces.
You want to pass these extra parameters to subprocess.Popen
:
bufsize=1, universal_newlines=True
Then you can iterate as in your example. (Tested with Python 3.5)

.so
files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.
.a
files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar
command -- a predecessor of tar
that's now just used for making libraries) of the original .o object files.
.la
files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?
Static and dynamic libraries each have pros and cons.
Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.
Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.
Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.
Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.
Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.
Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.
Dynamic libraries are especially useful for system libraries, like libc
. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.
Save:
public boolean saveFile(Context context, String mytext){
Log.i("TESTE", "SAVE");
try {
FileOutputStream fos = context.openFileOutput("file_name"+".txt",Context.MODE_PRIVATE);
Writer out = new OutputStreamWriter(fos);
out.write(mytext);
out.close();
return true;
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
Load:
public String load(Context context){
Log.i("TESTE", "FILE");
try {
FileInputStream fis = context.openFileInput("file_name"+".txt");
BufferedReader r = new BufferedReader(new InputStreamReader(fis));
String line= r.readLine();
r.close();
return line;
} catch (IOException e) {
e.printStackTrace();
Log.i("TESTE", "FILE - false");
return null;
}
}
You may like py2exe. You'll also find information in there for doing it on Linux.
Technically the answer of zlovelady is preferable, but as I had only to remove items from the navigation, the approach of unsetting the not-needed navigation items in the template was the fastest/easiest way for me:
Just duplicate
app/design/frontend/base/default/template/customer/account/navigation
to
app/design/frontend/YOUR_THEME/default/template/customer/account/navigation
and unset the unneeded navigation items before the get rendered, e.g.:
<?php $_links = $this->getLinks(); ?>
<?php
unset($_links['recurring_profiles']);
?>
There are two ways to write case statements, you seem to be using a combination of the two
case a.updatedDate
when 1760 then 'Entered on' + a.updatedDate
when 1710 then 'Viewed on' + a.updatedDate
else 'Last Updated on' + a.updateDate
end
or
case
when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
else 'Last Updated on' + a.updateDate
end
are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.
Currently, they are the same. but previously
VARCHAR
is reserved by Oracle to support distinction between NULL
and empty string in future, as ANSI standard prescribes.
VARCHAR2
does not distinguish between a NULL
and empty string, and never will.
Emp_name varchar(10)
- if you enter value less than 10 digits then remaining space cannot be deleted. it used total of 10 spaces.
Emp_name varchar2(10)
- if you enter value less than 10 digits then remaining space is automatically deleted
The official tutorial discusses deploying an app to production. One option is to use Waitress, a production WSGI server. Other servers include Gunicorn and uWSGI.
When running publicly rather than in development, you should not use the built-in development server (
flask run
). The development server is provided by Werkzeug for convenience, but is not designed to be particularly efficient, stable, or secure.Instead, use a production WSGI server. For example, to use Waitress, first install it in the virtual environment:
$ pip install waitress
You need to tell Waitress about your application, but it doesn’t use
FLASK_APP
like flask run does. You need to tell it to import and call the application factory to get an application object.$ waitress-serve --call 'flaskr:create_app' Serving on http://0.0.0.0:8080
Or you can use waitress.serve()
in the code instead of using the CLI command.
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "<h1>Hello!</h1>"
if __name__ == "__main__":
from waitress import serve
serve(app, host="0.0.0.0", port=8080)
$ python hello.py
Just make an http request to the required URL with correct query string, or request body.
For example you could use java.net.HttpURLConnection
and then consume via connection.getInputStream()
, and then covnert to your objects.
In spring there is a restTemplate
that makes it all a bit easier.
I know this is quite late to answer this question but I resolved this problem by myself and thought worth sharing it with everyone.`
public void replaceFragment(BaseFragment fragment) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

If you are using c# 3.0 (or above) you can use extenders
Environment variables (that you modify using the System Properties) are only propagated to subshells when you create a new subshell.
If you had a command line prompt (DOS or cygwin) open when you changed the User env vars, then they won't show up.
You need to open a new command line prompt after you change the user settings.
The equivalent in Unix/Linux is adding a line to your .bash_rc: you need to start a new shell to get the values.
Is there some simple equivalent to this keyword in C++?
No.
Depending on what you're trying to accomplish, there might be adequate (or even better) substitutes.
I've looked through some STL code (on linux, I think it's the one deriving from SGI's implementation). It has "concept assertions"; for instance, if you require a type which understands *x
and ++x
, the concept assertion would contain that code in a do-nothing function (or something similar). It does require some overhead, so it might be smart to put it in a macro whose definition depends on #ifdef debug
.
If the subclass relationship is really what you want to know about, you could assert in the constructor that T instanceof list
(except it's "spelled" differently in C++). That way, you can test your way out of the compiler not being able to check it for you.
I changed the Office365 password and then tried to send a test email and it worked like a charm for me.
I used the front end (database mail option) and settings as smtp.office365.com port number 587 and checked the secure connection option. use basic authentication and store the credentials. Hope this turns out useful for someone.
The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc
A set of simple examples:
Using Gson:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
public class Gson {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
com.google.gson.Gson gson = new com.google.gson.Gson();
Response respuesta = gson.fromJson(json, Response.class);
System.out.println(respuesta.getExample());
System.out.println(respuesta.getFr());
} catch (IOException ex) {
}
return null;
}
public class Response{
private String example;
private String fr;
public String getExample() {
return example;
}
public void setExample(String example) {
this.example = example;
}
public String getFr() {
return fr;
}
public void setFr(String fr) {
this.fr = fr;
}
}
}
Using json-simple:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class JsonSimple {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
try {
JSONParser parser = new JSONParser();
Object resultObject = parser.parse(json);
if (resultObject instanceof JSONArray) {
JSONArray array=(JSONArray)resultObject;
for (Object object : array) {
JSONObject obj =(JSONObject)object;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
}else if (resultObject instanceof JSONObject) {
JSONObject obj =(JSONObject)resultObject;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
} catch (Exception e) {
// TODO: handle exception
}
} catch (IOException ex) {
}
return null;
}
}
etc...
The answer might very well depend on the compiler, so you probably want to edit your question (I mean, even the notion of segments is not mandated by ISO C nor ISO C++). For instance, on Windows an executable doesn't carry symbol names. One 'foo' would be offset 0x100, the other perhaps 0x2B0, and code from both translation units is compiled knowing the offsets for "their" foo.
You can use newer OpenCV python interface (if I'm not mistaken it is available since OpenCV 2.2). It natively uses numpy arrays:
import cv2
im = cv2.imread("abc.tiff",mode='RGB')
print type(im)
result:
<type 'numpy.ndarray'>
Again I suggest Simple and Easy
Its Working Perfect with ajax when user search and select it saves the selected information via ajax
$("#vendor-brands").select2({
ajax: {
url:site_url('general/get_brand_ajax_json'),
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term, // search term
page: params.page
};
},
processResults: function (data, params) {
// parse the results into the format expected by Select2
// since we are using custom formatting functions we do not need to
// alter the remote JSON data, except to indicate that infinite
// scrolling can be used
params.page = params.page || 1;
return {
results: data,
pagination: {
more: (params.page * 30) < data.total_count
}
};
},
cache: true
},
escapeMarkup: function (markup) { return markup; }, // let our custom formatter work
minimumInputLength: 1,
}).on("change", function(e) {
var lastValue = $("#vendor-brands option:last-child").val();
var lastText = $("#vendor-brands option:last-child").text();
alert(lastValue+' '+lastText);
});
too late.. but I guess I have the answer -
Here's my sample study.df dataframe -

You may call U.difference(lists)
method in underscore-java library. I am the maintainer of the project. Live example
import com.github.underscore.U;
import java.util.Arrays;
import java.util.List;
public class Main {
public static void main(String[] args) {
List<Integer> list1 = Arrays.asList(1, 2, 3);
List<Integer> list2 = Arrays.asList(1, 2);
List<Integer> list3 = U.difference(list1, list2);
System.out.println(list3);
// [3]
}
}
My solution was to create a pipelined function. The advantages are that the query can be a single line:
select * from table(yourfunction(param1, param2));
To define the function you would need to do something like the following:
-- Declare the record columns
TYPE your_record IS RECORD(
my_col1 VARCHAR2(50),
my_col2 varchar2(4000)
);
TYPE your_results IS TABLE OF your_record;
-- Declare the function
function yourfunction(a_Param1 varchar2, a_Param2 varchar2)
return your_results pipelined is
rt your_results;
begin
-- Your query to load the table type
select s.col1,s.col2
bulk collect into rt
from your_table s
where lower(s.col1) like lower('%'||a_Param1||'%');
-- Stuff the results into the pipeline..
if rt.count > 0 then
for i in rt.FIRST .. rt.LAST loop
pipe row (rt(i));
end loop;
end if;
-- Add more results as you please....
return;
end find;
And as mentioned above, all you would do to view your results is:
select * from table(yourfunction(param1, param2)) t order by t.my_col1;
min(df['some_property'])
max(df['some_property'])
The built-in functions work well with Pandas Dataframes.
That's compiled code, you'll need to use a decompiler like JAD: http://www.kpdus.com/jad.html
You may want to look at this site to learn more about memory in the JVM: http://developer.streamezzo.com/content/learn/articles/optimization-heap-memory-usage
I have found it useful to use visualgc to watch how the different parts of the memory model is filling up, to determine what to change.
It is difficult to determine which part of memory was filled up, hence visualgc, as you may want to just change the part that is having a problem, rather than just say,
Fine! I will give 1G of RAM to the JVM.
Try to be more precise about what you are doing, in the long run you will probably find the program better for it.
To determine where the memory leak may be you can use unit tests for that, by testing what was the memory before the test, and after, and if there is too big a change then you may want to examine it, but, you need to do the check while your test is still running.

But in AWS Console: in your Lambda Environment variables just add:
KEY:JAVA_TOOL_OPTIONS
VALUE:-Dspring.profiles.active=dev
You could use setInterval
for this.
<script type="text/javascript">
function myFunction () {
console.log('Executed!');
}
var interval = setInterval(function () { myFunction(); }, 60000);
</script>
Disable the timer by setting clearInterval(interval)
.

My solution was to make sure that all IIS features are installed. So went to add remove programs in the control panel and clicked on add remove windows features and selected all options except IIS 6 console compatibility.
You must use the name of the subform control, not the name of the subform, though these are often the same:
Forms![MainForm]![subform control name Name].Form.Requery
Or, if you are on the main form:
Me.[subform control name Name].Form.Requery
More Info: http://www.mvps.org/access/forms/frm0031.htm
In my case this very same error was caused by the way I was importing my custom component from the caller class i.e. I was doing
import {MyComponent} from './components/MyComponent'
instead of
import MyComponent from './components/MyComponent'
using the latter solved the issue.
Returning false
from the function will stop the event continuing. I.e. it will stop the form submitting.
i.e.
function someFunction()
{
if (allow) // For example, checking that a field isn't empty
{
return true; // Allow the form to submit
}
else
{
return false; // Stop the form submitting
}
}
Another short solution:
from datetime import date
def diff_dates(date1, date2):
return abs(date2-date1).days
def main():
d1 = date(2013,1,1)
d2 = date(2013,9,13)
result1 = diff_dates(d2, d1)
print '{} days between {} and {}'.format(result1, d1, d2)
print ("Happy programmer's day!")
main()
You don't need to use array_push() function, you can assign new value with new key directly to the array like..
$array = array("color1"=>"red", "color2"=>"blue");
$array['color3']='green';
print_r($array);
Output:
Array(
[color1] => red
[color2] => blue
[color3] => green
)
You can use os.File (which implements the io.Reader interface) with the bufio package for that. However, those packages are build with fixed memory usage in mind (no matter how large the file is) and are quite fast.
Unfortunately this makes reading the whole file into the memory a bit more complicated. You can use a bytes.Buffer to join the parts of the line if they exceed the line limit. Anyway, I recommend you to try to use the line reader directly in your project (especially if do not know how large the text file is!). But if the file is small, the following example might be sufficient for you:
package main
import (
"os"
"bufio"
"bytes"
"fmt"
)
// Read a whole file into the memory and store it as array of lines
func readLines(path string) (lines []string, err os.Error) {
var (
file *os.File
part []byte
prefix bool
)
if file, err = os.Open(path); err != nil {
return
}
reader := bufio.NewReader(file)
buffer := bytes.NewBuffer(make([]byte, 1024))
for {
if part, prefix, err = reader.ReadLine(); err != nil {
break
}
buffer.Write(part)
if !prefix {
lines = append(lines, buffer.String())
buffer.Reset()
}
}
if err == os.EOF {
err = nil
}
return
}
func main() {
lines, err := readLines("foo.txt")
if err != nil {
fmt.Println("Error: %s\n", err)
return
}
for _, line := range lines {
fmt.Println(line)
}
}
Another alternative might be to use io.ioutil.ReadAll to read in the complete file at once and do the slicing by line afterwards. I don't give you an explicit example of how to write the lines back to the file, but that's basically an os.Create()
followed by a loop similar to that one in the example (see main()
).
Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.
Short answer to your question: Yes there are other stuff included than whats in the list.
What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.
From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.
Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.
Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.
If you know the full path to the file you can just do something similar to this. However if you question directly relates to relative paths, that I am unfamiliar with and would have to research and test.
path = 'C:\\Users\\Username\\Path\\To\\File'
with open(path, 'w') as f:
f.write(data)
Edit:
Here is a way to do it relatively instead of absolute. Not sure if this works on windows, you will have to test it.
import os
cur_path = os.path.dirname(__file__)
new_path = os.path.relpath('..\\subfldr1\\testfile.txt', cur_path)
with open(new_path, 'w') as f:
f.write(data)
Edit 2: One quick note about __file__
, this will not work in the interactive interpreter due it being ran interactively and not from an actual file.
txtSearch.onkeydown= e => (e.key=="Enter") ? btnSearch.click() : 1

Here is another solution, that has all the source available in a single, simple ZIP file.
It presents the OpenFileDialog with additional windows flags that makes it work like the Windows 7+ Folder Selection dialog.
Per the website, it is public domain: "There’s no license as such as you are free to take and do with the code what you will."
Archive.org links:
Use the download attribute.
var link = document.createElement('a');
link.href = url;
link.download = 'file.pdf';
link.dispatchEvent(new MouseEvent('click'));
If you are looking to render JSON as HTML and it can be collapsed/opened, you can use this directive that I just made to render it nicely:
You need to access a geocoding service (i.e. from Google), there is no simple formula to transfer addresses to geo coordinates.
The extra [ ] on the outside of your second syntax are unnecessary, and possibly confusing. You may use them, but if you must you need to have whitespace between them.
Alternatively:
while [ $stats -gt 300 ] || [ $stats -eq 0 ]
In my case, the route signature was different from the method parameter. I had id, but I was accepting documentId as parameter, that caused the problem.
[Route("Documents/{id}")] <--- caused the webapi error
[Route("Documents/{documentId}")] <-- solved
public Document Get(string documentId)
{
..
}
First of all you should configure $resource
in different manner: without query params in the URL. Default query parameters may be passed as properties of the second parameter in resource(url, paramDefaults, actions)
. It is also to be mentioned that you configure get
method of resource and using query
instead.

Your asp.net account {MACHINE}\ASPNET
does not have write access to that location. That is the reason why its failing.
Consider granting access rights to the resource to the ASP.NET request identity.
Right click on downloading folder Properties > Security Tab > Edit > Add > locations > choose your local machine > click OK > Type ASPNET below "Enter the object name to select" > Click Check Names
Check the boxes for the desired access (Full Control
). If it will not work for you do the same with Network Service
Now this should show your local {MACHINENAME}\ASPNET
account, then you set the write permission to this account.
Otherwise if the application is impersonating via <identity impersonate="true"/>
, the identity will be the anonymous user (typically IUSR_MACHINENAME
) or the authenticated request user.
Or just use dedicated location for storing files in ASP.NET which is App_Data
. To create it right click on your ASP.NET Project (in Visual Studio) Add > Add ASP.NET Folder > App_Data
. Then you'll be able to save data to this location:
var path = Server.MapPath("~/App_Data/file.txt");
System.IO.File.WriteAllText(path, "Hello World");
I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.
Sub
don't return values and function
s don't have side effects.
Sometimes you want both side effect and return value.
This is easy to be done once you know that VBA passes arguments by default by reference so you can write your code in this way:
Sub getValue(retValue as Long)
...
retValue = 42
End SUb
Sub Main()
Dim retValue As Long
getValue retValue
...
End SUb
TL;DR: Python does not need forward declarations. Simply put your function calls inside function def definitions, and you'll be fine.
def foo(count):
print("foo "+str(count))
if(count>0):
bar(count-1)
def bar(count):
print("bar "+str(count))
if(count>0):
foo(count-1)
foo(3)
print("Finished.")
recursive function definitions, perfectly successfully gives:
foo 3
bar 2
foo 1
bar 0
Finished.
However,
bug(13)
def bug(count):
print("bug never runs "+str(count))
print("Does not print this.")
breaks at the top-level invocation of a function that hasn't been defined yet, and gives:
Traceback (most recent call last):
File "./test1.py", line 1, in <module>
bug(13)
NameError: name 'bug' is not defined
Python is an interpreted language, like Lisp. It has no type checking, only run-time function invocations, which succeed if the function name has been bound and fail if it's unbound.
Critically, a function def definition does not execute any of the funcalls inside its lines, it simply declares what the function body is going to consist of. Again, it doesn't even do type checking. So we can do this:
def uncalled():
wild_eyed_undefined_function()
print("I'm not invoked!")
print("Only run this one line.")
and it runs perfectly fine (!), with output
Only run this one line.
The key is the difference between definitions and invocations.
The interpreter executes everything that comes in at the top level, which means it tries to invoke it. If it's not inside a definition.
Your code is running into trouble because you attempted to invoke a function, at the top level in this case, before it was bound.
The solution is to put your non-top-level function invocations inside a function definition, then call that function sometime much later.
The business about "if __ main __" is an idiom based on this principle, but you have to understand why, instead of simply blindly following it.
There are certainly much more advanced topics concerning lambda functions and rebinding function names dynamically, but these are not what the OP was asking for. In addition, they can be solved using these same principles: (1) defs define a function, they do not invoke their lines; (2) you get in trouble when you invoke a function symbol that's unbound.
Many thanks to Mfoo who has put the really nice script for adding columns dynamically if not exists in the table. I have improved his answer with PHP. The script additionally helps you find how many tables actually needed 'Add column' mysql comand. Just taste the recipe. Works like charm.
<?php
ini_set('max_execution_time', 0);
$host = 'localhost';
$username = 'root';
$password = '';
$database = 'books';
$con = mysqli_connect($host, $username, $password);
if(!$con) { echo "Cannot connect to the database ";die();}
mysqli_select_db($con, $database);
$result=mysqli_query($con, 'show tables');
$tableArray = array();
while($tables = mysqli_fetch_row($result))
{
$tableArray[] = $tables[0];
}
$already = 0;
$new = 0;
for($rs = 0; $rs < count($tableArray); $rs++)
{
$exists = FALSE;
$result = mysqli_query($con, "SHOW COLUMNS FROM ".$tableArray[$rs]." LIKE 'tags'");
$exists = (mysqli_num_rows($result))?TRUE:FALSE;
if($exists == FALSE)
{
mysqli_query($con, "ALTER TABLE ".$tableArray[$rs]." ADD COLUMN tags VARCHAR(500) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL");
++$new;
echo '#'.$new.' Table DONE!<br/>';
}
else
{
++$already;
echo '#'.$already.' Field defined alrady!<br/>';
}
echo '<br/>';
}
?>
Web containers are responsible to provide the run time environment to web applications. It contains components that provide naming context and manages the life cycle of a web application. Web containers are a part of a web server and they generally processes the user request and send a static response.
Servlet containers are the one where JSP created components reside. They are basically responsible to provide dynamic content as per the user request. Basically, Web containers reply with a static content as per the user request, but Servlets can create the dynamic pages.
$.fn.extend({
hasClasses: function (selectors) {
var self = this;
for (var i in selectors) {
if ($(self).hasClass(selectors[i]))
return true;
}
return false;
}
});
$('#element').hasClasses(['class1', 'class2', 'class3']);
This should do it, simple and easy.
Unbelievable, but on httpd 2.2 on centos 6.4 this works.
Export env vars in /etc/sysconfig/httpd
export mydocroot=/var/www/html
Then simply do this...
<VirtualHost *:80>
DocumentRoot ${mydocroot}
</VirtualHost>
Then finally....
service httpd restart;
You might be looking for process.env.PORT
. This allows you to dynamically set the listening port using what are called "environment variables". The Node.js code would look like this:
const port = process.env.PORT || 3000;
app.listen(port, () => {console.log(`Listening on port ${port}...`)});
You can even manually set the dynamic variable in the terminal using export PORT=5000
, or whatever port you want.
I had this challenge when working on MySQL Ver 8.0.21
I wanted to grant permissions of a database named my_app_db
to the root
user running on localhost
host.
But when I run the command:
use my_app_db;
GRANT ALL PRIVILEGES ON my_app_db.* TO 'root'@'localhost';
I get the error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'my_app_db.* TO 'root'@'localhost'' at line 1>
Here's how I fixed:
Login to your MySQL console. You can change root
to the user you want to login with:
mysql -u root -p
Enter your mysql root password
Next, list out all the users and their host on the MySQL server. Unlike PostgreSQL this is often stored in the mysql
database. So we need to select the mysql
database first:
use mysql;
SELECT user, host FROM user;
Note: if you don't run the use mysql
, you get the no database selected
error.
This should give you an output of this sort:
+------------------+-----------+
| user | host |
+------------------+-----------+
| mysql.infoschema | localhost |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+------------------+-----------+
4 rows in set (0.00 sec)
Next, based on the information gotten from the list, grant privileges to the user that you want. We will need to first select the database before granting permission to it. For me, I am using the root
user that runs on the localhost
host:
use my_app_db;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
Note: The GRANT ALL PRIVILEGES ON database_name.* TO 'root'@'localhost';
command may not work for modern versions of MySQL. Most modern versions of MyQL replace the database_name
with *
in the grant privileges command after you select the database that you want to use.
You can then exit the MySQL console:
exit
That's it.
I hope this helps
The solution was to call...
$scope.$apply();
...in my jQuery event callback.
What is the type of c.PhysicalAddresses
? If it's Dictionary<TKey,TValue>
, then you can use the ContainsKey
method.
Jeroen Vervaeke's answer is modular and the works fine, but it can cause problems if it is using with jQuery or other libraries that count on "object-as-hashtables" feature of Javascript.
I modified it a little to make usable with these libs.
function getByIndex(obj, index) {
return obj[Object.keys(obj)[index]];
}
The question has already been marked as answered, But I guess the question states that the person wants to remove multiple columns from a DataTable
.
So for that, here is what I did, when I came across the same problem.
string[] ColumnsToBeDeleted = { "col1", "col2", "col3", "col4" };
foreach (string ColName in ColumnsToBeDeleted)
{
if (dt.Columns.Contains(ColName))
dt.Columns.Remove(ColName);
}
Try this instead:
print_r($sth->errorInfo());
Add this before your prepare:
$this->pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );
This will change the PDO error reporting type and cause it to emit a warning whenever there is a PDO error. It should help you track it down, although your errorInfo should have bet set.
You could try using the -Clear
parameter
Example:-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName
Don't modify the list inside of a loop which iterates through the list.
Instead, use a for()
or while()
with an index, going backwards through the list. (This will let you delete things without getting an invalid index.)
var foo = new List<Bar>();
for(int i = foo.Count-1; i >= 0; --i)
{
var item = foo[i];
// do something with item
}

Here's some other options for you:
https://stackoverflow.com/a/23420490/1004312
Since the fixed position in general is not all that stable on touch (some more than others, Chrome works great), it is still acting up in Safari IOS 8 in situations that used to work in IOS 7, therefore I generally just use JS to detect touch devices, including Windows mobile.

Field data represents some information stored in the class.
Class implements the Serializable
interface,
so eclipse automatically offered to declare the serialVersionUID
field. Lets start with value 1 set there.
If you don't want that warning to come, use this:
@SuppressWarnings("serial")
Take a look at the getopt library; it's pretty much the gold standard for this sort of thing.
Constant initializer allowed by C++ Standard only for integral or enumeration types. See 9.4.2/4 for details:
If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a name- space scope if it is used in the program and the namespace scope definition shall not contain an initializer.
And 9.4.2/7:
Static data members are initialized and destroyed exactly like non-local objects (3.6.2, 3.6.3).
So you should write somewhere in cpp file:
const char* SomeClass::SOMETHING = "sommething";
My Comments:
When I see the output, the output is mixed with One, Two, Three which are the thread names and they run simultaneously. I am not sure when you say thread is not running by main method.
Not sure if I understood your question or not. But I m putting my answer what I could understand, hope it can help you.
1) Then you created the object, it called the constructor, in construct it has start method which started the thread and executed the contents written inside run() method.
So as you created 3 objects (3 threads - one, two, three), all 3 threads started executing simultaneously.
2) Join and Synchronization They are 2 different things, Synchronization is when there are multiple threads sharing a common resource and one thread should use that resource at a time. E.g. Threads such as DepositThread, WithdrawThread etc. do share a common object as BankObject. So while DepositThread is running, the WithdrawThread will wait if they are synchronized. wait(), notify(), notifyAll() are used for inter-thread communication. Plz google to know more.
about Join(), it is when multiple threads are running, but you join. e.g. if there are two thread t1 and t2 and in multi-thread env they run, the output would be: t1-0 t2-0 t1-1 t2-1 t1-2 t2-2
and we use t1.join(), it would be: t1-0 t1-1 t1-2 t2-0 t2-1 t2-2
This is used in realtime when sometimes you don't mix up the thread in certain conditions and one depends another to be completed (not in shared resource), so you can call the join() method.
You could just add one needed external jar file to the project. Go to your project-->java build path-->libraries, add external JARS.Then add your downloaded file from the formal website. My default name is commons-codec-1.10.jar

Also check this answer from here: Cannot manually edit applicationhost.config
The answer is simple, if not that obvious: win2008 is 64bit, notepad++ is 32bit. When you navigate to Windows\System32\inetsrv\config using explorer you are using a 64bit program to find the file. When you open the file using using notepad++ you are trying to open it using a 32bit program. The confusion occurs because, rather than telling you that this is what you are doing, windows allows you to open the file but when you save it the file's path is transparently mapped to Windows\SysWOW64\inetsrv\Config.
So in practice what happens is you open applicationhost.config using notepad++, make a change, save the file; but rather than overwriting the original you are saving a 32bit copy of it in Windows\SysWOW64\inetsrv\Config, therefore you are not making changes to the version that is actually used by IIS. If you navigate to the Windows\SysWOW64\inetsrv\Config you will find the file you just saved.
How to get around this? Simple - use a 64bit text editor, such as the normal notepad that ships with windows.

OLD ANSWER
@outlyer's answer is correct, but there're some changes in new Glide version
My version: 4.7.1
Code:
Glide.with(context.applicationContext)
.asBitmap()
.load(iconUrl)
.into(object : SimpleTarget<Bitmap>(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL) {
override fun onResourceReady(resource: Bitmap, transition: com.bumptech.glide.request.transition.Transition<in Bitmap>?) {
callback.onReady(createMarkerIcon(resource, iconId))
}
})
Note: this code run in UI Thread, thus you can use AsyncTask, Executor or somethings else for concurrency (like @outlyer's code) If you want to get original size, put Target.SIZE_ORIGINA as my code. Don't use -1, -1

what about this
<FORM METHOD="post" ACTION="mailto:[email protected]" ENCTYPE="multipart/form-data">

If you're already using Apache commons, it provides a static method for this:
StringEscapeUtils.escapeJson("some string")
It converts any string into one that's properly escaped for inclusion in JSON
if([UIDevice currentDevice].userInterfaceIdiom==UIUserInterfaceIdiomPad) {
//Device is ipad
}else{
//Device is iphone
}
Response.Write("<script> try {this.submit();} catch(e){} </script>");
You could use hashname.key(valuename)
Or, an inversion may be in order. new_hash = hashname.invert
will give you a new_hash
that lets you do things more traditionally.
There is an 'exceptions' window in VS2005 ... try Ctrl+Alt+E when debugging and click on the 'Thrown' checkbox for the exception you want to stop on.
Just use the modulus
loop through the list and run the following on each item
if(num % 2 == 0)
{
//is even
}
else
{
//is odd
}
Alternatively if you want to know if all are even you can do something like this:
bool allAreEven = lst.All(x => x % 2 == 0);
This error occures when you try to refer to a null object instance. I can`t tell you what causes this error by your given information, but you can debug it easily in your IDE. I strongly recommend you that use exception handling to avoid unexpected program behavior.
For creating a console-based UI, you can use gui.cs. It is open-source (from Miguel de Icaza, creator of Xamarin), and runs on .NET Core on Windows, Linux, and macOS.
It has the following components:
Sample screenshot
Pandas has the itertuples
method to do exactly this:
list(df[['lat', 'long']].itertuples(index=False, name=None))
setInterval()
is a time interval based code execution method that has the native ability to repeatedly run a specified script when the interval is reached. It should not be nested into its callback function by the script author to make it loop, since it loops by default. It will keep firing at the interval unless you call clearInterval()
.
If you want to loop code for animations or on a clock tick, then use setInterval()
.
function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setInterval(doStuff, 5000);
setTimeout()
is a time based code execution method that will execute a script only one time when the interval is reached. It will not repeat again unless you gear it to loop the script by nesting the setTimeout()
object inside of the function it calls to run. If geared to loop, it will keep firing at the interval unless you call clearTimeout()
.
function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setTimeout(doStuff, 5000);
If you want something to happen one time after a specified period of time, then use setTimeout()
. That is because it only executes one time when the specified interval is reached.
Printing the STACK trace, logging it or send message to the user, are very bad ways to process the exceptions. Does any one can describe solutions to fix the exception in proper steps then can trying the broken instruction again?
I was actually running into some strange errors with mp4's a while ago. What fixed it for me was re-encoding the video using known supported codecs (H.264 & MP3).
I actually used the VLC player to do so and it worked fine afterward. I converted using the mentioned codecs H.264/MP3. That solved it for me.
Maybe the problem is not in the format
but in the JavaScript
implementation of the play/ pause
methods. May I suggest visiting the following link where Google developer explains it in a good way?
Additionally, you could choose to use the newer webp
format, which Chrome supports out of the box, but be careful with other browsers. Check the support for it before implementation. Here's a link that describes the mentioned format.
On that note: I've created a small script
that easily converts all standard formats to webp
. You can easily configure it to fit your needs. Here's the Github repo of the same projects.
I actually used this script to replace a line of code in the cron file on our company's UNIX servers awhile back. We executed it as normal shell script and had no problems:
#Create temporary file with new line in place
cat /dir/file | sed -e "s/the_original_line/the_new_line/" > /dir/temp_file
#Copy the new file over the original file
mv /dir/temp_file /dir/file
This doesn't go by line number, but you can easily switch to a line number based system by putting the line number before the s/
and placing a wildcard in place of the_original_line
.
You can do it with a cursor also. Assuming that you have created an Account and a Profile e.g. "profile" and an Account and you have the table that holds the emails ready e.g. "EmailMessageTable" you can do the following:
USE database_name
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE mass_email AS
declare @email nvarchar (50)
declare @body nvarchar (255)
declare test_cur cursor for
SELECT email from [dbo].[EmailMessageTable]
open test_cur
fetch next from test_cur into
@email
while @@fetch_status = 0
begin
set @body = (SELECT body from [dbo].[EmailMessageTable] where email = @email)
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'profile',
@recipients = @email,
@body = @body,
@subject = 'Credentials for Web';
fetch next from test_cur into
@email
end
close test_cur
deallocate test_cur
After that all you have to do is execute the Stored Procedure
EXECUTE mass_email
GO
<?php _x000D_
_x000D_
$terms = get_terms( array(_x000D_
'taxonomy' => 'product_cat',_x000D_

) ); // Get Terms_x000D_

foreach ($terms as $key => $value) _x000D_
{_x000D_
$metaterms = get_term_meta($value->term_id);_x000D_
$thumbnail_id = get_woocommerce_term_meta($value->term_id, 'thumbnail_id', true );_x000D_
$image = wp_get_attachment_url( $thumbnail_id );_x000D_

Okay, but you all know that the * is a wildcard and allows cross site scripting from every domain?
You would like to send multiple Access-Control-Allow-Origin
headers for every site that's allowed to - but unfortunately its officially not supported to send multiple Access-Control-Allow-Origin
headers, or to put in multiple origins.
You can solve this by checking the origin, and sending back that one in the header, if it is allowed:
$origin = $_SERVER['HTTP_ORIGIN'];
$allowed_domains = [
'http://mysite1.com',
'https://www.mysite2.com',
'http://www.mysite2.com',
];
if (in_array($origin, $allowed_domains)) {
header('Access-Control-Allow-Origin: ' . $origin);
}
Thats much safer. You might want to edit the matching and change it to a manual function with some regex, or something like that. At least this will only send back 1 header, and you will be sure its the one that the request came from. Please do note that all HTTP headers can be spoofed, but this header is for the client's protection. Don't protect your own data with those values. If you want to know more, read up a bit on CORS and CSRF.
Why is it safer?
Allowing access from other locations then your own trusted site allows for session highjacking. I'm going to go with a little example - image Facebook allows a wildcard origin - this means that you can make your own website somewhere, and make it fire AJAX calls (or open iframes) to facebook. This means you can grab the logged in info of the facebook of a visitor of your website. Even worse - you can script POST
requests and post data on someone's facebook - just while they are browsing your website.
Be very cautious when using the ACAO
headers!
although these answers fix the problem but this could be some useful
class MainNavigatioController: UINavigationController {
override func pushViewController(_ viewController: UIViewController, animated: Bool) {
// first
let backItem = UIBarButtonItem()
backItem.title = "????"
self.viewControllers.last?.navigationItem.backBarButtonItem = backItem
// then
super.pushViewController(viewController, animated: animated)
}
}
There may be many ways.. But I implemented by following two ways
Given example is of maven project.
1. Using Dockerfile in maven project
Use the following file structure:
Demo
+-- src
| +-- main
| ¦ +-- java
| ¦ +-- org
| ¦ +-- demo
| ¦ +-- Application.java
| ¦
| +-- test
|
+---- Dockerfile
+---- pom.xml
And update the Dockerfile as:
FROM java:8
EXPOSE 8080
ADD /target/demo.jar demo.jar
ENTRYPOINT ["java","-jar","demo.jar"]
Navigate to the project folder and type following command you will be ab le to create image and run that image:
$ mvn clean
$ mvn install
$ docker build -f Dockerfile -t springdemo .
$ docker run -p 8080:8080 -t springdemo
Get video at Spring Boot with Docker
2. Using Maven plugins
Add given maven plugin in pom.xml
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.5</version>
<configuration>
<imageName>springdocker</imageName>
<baseImage>java</baseImage>
<entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
Navigate to the project folder and type following command you will be able to create image and run that image:
$ mvn clean package docker:build
$ docker images
$ docker run -p 8080:8080 -t <image name>
In first example we are creating Dockerfile and providing base image and adding jar an so, after doing that we will run docker command to build an image with specific name and then run that image..
Whereas in second example we are using maven plugin in which we providing baseImage
and imageName
so we don't need to create Dockerfile here.. after packaging maven project we will get the docker image and we just need to run that image..
Put the Text in a Center:
Container(
height: 45,
color: Colors.black,
child: Center(
child: Text(
'test',
style: TextStyle(color: Colors.white),
),
),
);
If you're attempting to do this in a .NET Standard library, here's a simple solution, with all of the risks of just returning true
in your handler. I leave safety up to you.
var handler = new HttpClientHandler();
handler.ClientCertificateOptions = ClientCertificateOption.Manual;
handler.ServerCertificateCustomValidationCallback =
(httpRequestMessage, cert, cetChain, policyErrors) =>
{
return true;
};
var client = new HttpClient(handler);
My pseudocode example will be as follows:
JSONArray jsonArray = "[{id:\"1\", name:\"sql\"},{id:\"2\",name:\"android\"},{id:\"3\",name:\"mvc\"}]";
JSON newJson = new JSON();
for (each json in jsonArray) {
String id = json.get("id");
String name = json.get("name");
newJson.put(id, name);
}
return newJson;
Quoting the Pandas docs
pandas.DataFrame(data=None, index=None, columns=None, dtype=None, copy=False)
Two-dimensional size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns). Arithmetic operations align on both row and column labels. Can be thought of as a dict-like container for Series objects. The primary pandas data structure.
So, the Series is the data structure for a single column of a DataFrame
, not only conceptually, but literally, i.e. the data in a DataFrame
is actually stored in memory as a collection of Series
.
Analogously: We need both lists and matrices, because matrices are built with lists. Single row matricies, while equivalent to lists in functionality still cannot exist without the list(s) they're composed of.
They both have extremely similar APIs, but you'll find that DataFrame
methods always cater to the possibility that you have more than one column. And, of course, you can always add another Series
(or equivalent object) to a DataFrame
, while adding a Series
to another Series
involves creating a DataFrame
.
Below command will work in command prompt:
copy c:\folder\file.ext \\dest-machine\destfolder /Z /Y
To Copy all files:
copy c:\folder\*.* \\dest-machine\destfolder /Z /Y
I just had a similar issue on a CentOS 5 server where I installed python 2.7.12 in /usr/local on top of a much older version of python2.7. Upgrading to CentOS 6 or 7 isn't an option on this server right now.
Some of the python 2.7 modules were still existing from the older version of python, but pip was failing to upgrade because the newer cryptography package is not supported by the CentOS 5 packages.
Specifically, 'pip install requests[security]' was failing because the openssl version on the CentOS 5 was 0.9.8e which is no longer supported by cryptography > 1.4.0.
To solve the OPs original issue I did:
1) pip install 'cryptography<1.3.5,>1.3.0'.
This installed cryptography 1.3.4 which works with openssl-0.9.8e. cryptograpy 1.3.4 is also sufficient to satisfy the requirement for the following command.
2) pip install 'requests[security]'
This command now installs because it doesn't try to install cryptography > 1.4.0.
Note that on Centos 5 I also needed to:
yum install openssl-devel
To allow cryptography to build
I typed this in my URL bar:
javascript:{ var col = 'screwdriver'; var x = '<option value="' + col + '"' + ((col == 'screwdriver') ? ' selected' : '') + '>Very roomy</option>'; alert(x); }
Other methods also exist to check but I prefer the following method as my best to check (as you can easily check types of other objects).

You need to specify the number of rows which should be deleted. In your case (and I assume that you only want to keep one) this can be done like this:
DELETE FROM your_table WHERE id_users=1 AND id_product=2
LIMIT (SELECT COUNT(*)-1 FROM your_table WHERE id_users=1 AND id_product=2)
Swift 2.1
var array = ["0","1","2","3"]

Yes, if bar is not None
is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar:
will execute if bar
is any kind of zero or empty container, or False
.
Many people do use not bar
where they really do mean bar is not None
.

@outis's answer is good: concise and correct as regards relations.
However, the situation is slightly more complicated as regards SQL.
Consider the usual suppliers and parts database but implemented in SQL:
SELECT * FROM S NATURAL JOIN SP;
would return a resultset** with columns
SNO, SNAME, STATUS, CITY, PNO, QTY
The join is performed on the column with the same name in both tables, SNO
. Note that the resultset has six columns and only contains one column for SNO
.
Now consider a theta eqijoin, where the column names for the join must be explicitly specified (plus range variables S
and SP
are required):
SELECT * FROM S JOIN SP ON S.SNO = SP.SNO;
The resultset will have seven columns, including two columns for SNO
. The names of the resultset are what the SQL Standard refers to as "implementation dependent" but could look like this:
SNO, SNAME, STATUS, CITY, SNO, PNO, QTY
or perhaps this
S.SNO, SNAME, STATUS, CITY, SP.SNO, PNO, QTY
In other words, NATURAL JOIN
in SQL can be considered to remove columns with duplicated names from the resultset (but alas will not remove duplicate rows - you must remember to change SELECT
to SELECT DISTINCT
yourself).
** I don't quite know what the result of SELECT * FROM table_expression;
is. I know it is not a relation because, among other reasons, it can have columns with duplicate names or a column with no name. I know it is not a set because, among other reasons, the column order is significant. It's not even a SQL table or SQL table expression. I call it a resultset.
I faced this issue when I had used Open SSL and the solution was to split the cert in 3 files and use all of them doing the call with Curl:

openssl pkcs12 -in mycert.p12 -out client.pem -clcerts -nokeys
openssl pkcs12 -in mycert.p12 -out key.pem -nocerts

INSERT INTO TABLE pd_temp(dept,make,cost,id,asmb_city,asmb_ct,retail) VALUES('production','thailand',10,99202,'northcarolina','usa',20)
As Constructor should be at the starting of the Class , you are facing the above issue . So, you can either change the name or if you want to use it as a constructor just copy the method at the beginning of the class.

Here we're exiting with a status code of 1. It is usually also helpful to output an error message, write to a log, and clean up.
First off, when you create a "bare repository", you're not going to be doing any work with it (it doesn't contain a working copy, so the git branch
command is not useful).
Now, the reason you wouldn't have a master
branch even after doing a git init
is that there are no commits: when you create your first commit, you will then have a master
branch.
From MySQL 5.7 onwards, this is possible, but requires first enabling the mdl
instrument in the performance_schema.setup_instruments
table. You can do this temporarily (until the server is next restarted) by running:
UPDATE performance_schema.setup_instruments
SET enabled = 'YES'
WHERE name = 'wait/lock/metadata/sql/mdl';
Or permanently, by adding the following incantation to the [mysqld]
section of your my.cnf
file (or whatever config files MySQL reads from on your installation):
[mysqld]
performance_schema_instrument = 'wait/lock/metadata/sql/mdl=ON'
(Naturally, MySQL will need to be restarted to make the config change take effect if you take the latter approach.)
Locks you take out after the mdl
instrument has been enabled can be seen by running a SELECT
against the performance_schema.metadata_locks
table. As noted in the docs, GET_LOCK
locks have an OBJECT_TYPE
of 'USER LEVEL LOCK'
, so we can filter our query down to them with a WHERE
clause:
mysql> SELECT GET_LOCK('foobarbaz', -1);

The meanings of the columns in this result are mostly adequately documented at https://dev.mysql.com/doc/refman/en/metadata-locks-table.html, but one point of confusion is worth noting: the OWNER_THREAD_ID
column does not contain the connection ID (like would be shown in the PROCESSLIST
or returned by CONNECTION_ID()
) of the thread that holds the lock. Confusingly, the term "thread ID" is sometimes used as a synonym of "connection ID" in the MySQL documentation, but this is not one of those times. If you want to determine the connection ID of the connection that holds a lock (for instance, in order to kill that connection with KILL
), you'll need to look up the PROCESSLIST_ID
that corresponds to the THREAD_ID
in the performance_schema.threads
table. For instance, to kill the connection that was holding my lock above...
mysql> SELECT OWNER_THREAD_ID FROM performance_schema.metadata_locks
-> WHERE OBJECT_TYPE='USER LEVEL LOCK'
-> AND OBJECT_NAME='foobarbaz';
+-----------------+
| OWNER_THREAD_ID |
+-----------------+
| 35 |
+-----------------+

In typescript you can do the following to suppress the error
:
let subString?: string;
subString > !null;
- Note the added exclamation mark before null.
For example if you have two div in XHTML document.
<div id='div1'>
<p>hello, how are you?</p>
<div id='div2'>
<p>I am fine, thank you.</p>
</div>
</div>
Then try this in CSS.
#div1 > #div2 > p{
color: red;
}
affect only 'div2' paragraph.
#div1 > p {
color: red;
}
affect only 'div1' paragraph.
pyplot
is a sub-module of matplotlib
which doesn't get imported with a simple import matplotlib
.
>>> import matplotlib
>>> print matplotlib.pyplot
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
>>> import matplotlib.pyplot
>>>
It seems customary to do: import matplotlib.pyplot as plt
at which time you can use the various functions and classes it contains:
p = plt.plot(...)
EDITED: turns out that I had forgotten the quotes needed for $entry
in order to print correctly and not give the "no such file or directory" error. Thank you all so much for helping me!
Here is my final code:
echo "Please type in the directory you want all the files to be listed with last modified dates" #bash can't find file creation dates
read directory
for entry in "$directory"/*
do
modDate=$(stat -c %y "$entry") #%y = last modified. Qoutes are needed otherwise spaces in file name with give error of "no such file"
modDate=${modDate%% *} #%% takes off everything off the string after the date to make it look pretty
echo $entry:$modDate
Prints out like this:

SQL Server equivalents to Excel's string-based DEC2HEX, HEX2DEC functions:
--Convert INT to hex string:
PRINT CONVERT(VARCHAR(8),CONVERT(VARBINARY(4), 16777215),2) --DEC2HEX
--Convert hex string to INT:
PRINT CONVERT(INT,CONVERT(VARBINARY(4),'00FFFFFF',2)) --HEX2DEC
A simple way to do this is to use StringIO.StringIO
(python2) or io.StringIO
(python3) and pass that to the pandas.read_csv
function. E.g:
import sys
if sys.version_info[0] < 3:
from StringIO import StringIO
else:
from io import StringIO
import pandas as pd
TESTDATA = StringIO("""col1;col2;col3
1;4.4;99
2;4.5;200
3;4.7;65
4;3.2;140
""")
df = pd.read_csv(TESTDATA, sep=";")
From a controller you can also return an Object/Array and it will be sent as a JSON response (including the correct HTTP headers).
public function show($id)
{
return Customer::find($id);
}
Unable to load Client Print Control!
Everytime, clients wanted to print report by clicking the button print on their report viewer, they always got this error message.
I had spent nearly two weeks to fix this problem.
My environment is:
- Window Server 2003 Standard Edition R2
- Report Server Version 10.X.X.X
- Clients with windowXP SP3
My Solution is:
- Replacing the CAP file (RSClientPrint-x86.cab) in C\Program Files\Microsoft SQL
Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin\
- Extract the RSClientPrint-x86.cab and destribute it to clients.
Hear is the CAB file: https://sites.google.com/site/narithsite/Home/RSClientPrint-x86.cab?attredirects=0&d=1
If BalusC answer doesn't work try this:
.companyHeaderGrid td {
border-style: hidden !important;
}
In addition to REMOTE_ADDR
and HTTP_X_FORWARDED_FOR
there are some other headers that can be set such as:
HTTP_CLIENT_IP
HTTP_X_FORWARDED_FOR
can be comma delimited list of IPsHTTP_X_FORWARDED
HTTP_X_CLUSTER_CLIENT_IP
HTTP_FORWARDED_FOR
HTTP_FORWARDED
I found the code on the following site useful:
http://www.grantburton.com/?p=97
C# solution:
public int solution(int[] A)
{
int result = 1;
// write your code in Java SE 8
foreach(int num in A)
{
if (num == result)
result++;
while (A.Contains(result))
result++;
}
return result;
}
If there are multiple certificates in a pfx file (key + corresponding certificate and a CA certificate) then this command worked well for me:
certutil -importpfx c:\somepfx.pfx this works but still a password is needed to be typed in manually for private key. Including -p and "password" cause error too many arguments for certutil on XP
In the first code sample, a
is a main
method local variable. Method local variables need to be initialized before using them.
In the second code sample, a
is class member variable, hence it will be initialized to the default value.
In my case, I have to calculate the difference in minutes and julianday()
does not give an accurate value. Instead, I use strftime()
:
SELECT (strftime('%s', [UserEnd]) - strftime('%s', [UserStart])) / 60
Both dates are converted to unixtime (seconds), then subtracted to get value in seconds between the two dates. Next, divide it by 60.
Wallacer's answer is nice, but one more checking is needed.
If file has no extension, it will use filename as extension which is not good.
Try this one:
return ( filename.indexOf('.') > 0 ) ? filename.split('.').pop().toLowerCase() : 'undefined';
If the modulus is a power of 2 then you can use a bitmask:
int i = -1 & ~-2; // -1 MOD 2 is 1
By comparison the Pascal language provides two operators; REM takes the sign of the numerator (x REM y
is x - (x DIV y) * y
where x DIV y
is TRUNC(x / y)
) and MOD requires a positive denominator and returns a positive result.
I recommend the method given by doofledorfer.
If you really want to do it via a direct API call, then look at the OpenSCManager function. Below are sample functions to take a machine name and service, and stop or start them.
function ServiceStart(sMachine, sService : string) : boolean; //start service, return TRUE if successful
var schm, schs : SC_Handle;
ss : TServiceStatus;
psTemp : PChar;
dwChkP : DWord;
begin
ss.dwCurrentState := 0;
schm := OpenSCManager(PChar(sMachine),Nil,SC_MANAGER_CONNECT); //connect to the service control manager
if(schm > 0)then begin // if successful...
schs := OpenService( schm,PChar(sService),SERVICE_START or SERVICE_QUERY_STATUS); // open service handle, start and query status
if(schs > 0)then begin // if successful...
psTemp := nil;
if (StartService(schs,0,psTemp)) and (QueryServiceStatus(schs,ss)) then
while(SERVICE_RUNNING <> ss.dwCurrentState)do begin
dwChkP := ss.dwCheckPoint; //dwCheckPoint contains a value incremented periodically to report progress of a long operation. Store it.
Sleep(ss.dwWaitHint); //Sleep for recommended time before checking status again
if(not QueryServiceStatus(schs,ss))then
break; //couldn't check status
if(ss.dwCheckPoint < dwChkP)then
Break; //if QueryServiceStatus didn't work for some reason, avoid infinite loop
end; //while not running
CloseServiceHandle(schs);
end; //if able to get service handle
CloseServiceHandle(schm);
end; //if able to get svc mgr handle
Result := SERVICE_RUNNING = ss.dwCurrentState; //if we were able to start it, return true
end;
function ServiceStop(sMachine, sService : string) : boolean; //stop service, return TRUE if successful
var schm, schs : SC_Handle;
ss : TServiceStatus;
dwChkP : DWord;
begin
schm := OpenSCManager(PChar(sMachine),nil,SC_MANAGER_CONNECT);
if(schm > 0)then begin
schs := OpenService(schm,PChar(sService),SERVICE_STOP or SERVICE_QUERY_STATUS);
if(schs > 0)then begin
if (ControlService(schs,SERVICE_CONTROL_STOP,ss)) and (QueryServiceStatus(schs,ss)) then
while(SERVICE_STOPPED <> ss.dwCurrentState) do begin
dwChkP := ss.dwCheckPoint;
Sleep(ss.dwWaitHint);
if(not QueryServiceStatus(schs,ss))then
Break;
if(ss.dwCheckPoint < dwChkP)then
Break;
end; //while
CloseServiceHandle(schs);
end; //if able to get svc handle
CloseServiceHandle(schm);
end; //if able to get svc mgr handle
Result := SERVICE_STOPPED = ss.dwCurrentState;
end;
Do I really have to first convert it into an array of arrays of key-value pairs?
No, an iterator of key-value pair arrays is enough. You can use the following to avoid creating the intermediate array:
function* entries(obj) {
for (let key in obj)
yield [key, obj[key]];
}
const map = new Map(entries({foo: 'bar'}));
map.get('foo'); // 'bar'
