.catch(error => { throw error})
is a no-op. It results in unhandled rejection in route handler.
As explained in this answer, Express doesn't support promises, all rejections should be handled manually:
router.get("/emailfetch", authCheck, async (req, res, next) => {
try {
//listing messages in users mailbox
let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
emailFetch = emailFetch.data
res.send(emailFetch)
} catch (err) {
next(err);
}
})
I had a similar problem in Visual Studio Code.
I solved by changing the remote url to https. (in file .git/config)
[remote "origin"]
url = https://[email protected]/plesk-git/project.git
and also
git config --global credential.helper wincred
pulled again, windows credential popup came out, problems solved.
I think that, we don't need parse the JSON object into a string, if the remote server accepts json into they request, just run:
const request = await fetch ('/echo/json', {
headers: {
'Content-type': 'application/json'
},
method: 'POST',
body: { a: 1, b: 2 }
});
Such as the curl request
curl -v -X POST -H 'Content-Type: application/json' -d '@data.json' '/echo/json'
In case to the remote serve not accept a json file as the body, just send a dataForm:
const data = new FormData ();
data.append ('a', 1);
data.append ('b', 2);
const request = await fetch ('/echo/form', {
headers: {
'Content-type': 'application/x-www-form-urlencoded'
},
method: 'POST',
body: data
});
Such as the curl request
curl -v -X POST -H 'Content-type: application/x-www-form-urlencoded' -d '@data.txt' '/echo/form'
In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.
I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?
Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,
There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.
The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).
Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

**Explanation:
------------**
The best way to deal with showModalDialog for older application conversions is use to `https://github.com/niutech/showModalDialog` inorder to work with show modal dialogs and if modal dailog has ajax calls you need to create object and set the parameters of function to object and pass below...before that check for browser and set the useragent...example: agentStr = navigator.userAgent; and then check for chrome
var objAcceptReject={}; // create empty object and set the parameters to object and send to the other functions as dialog when opened in chrome breaks the functionality
function rejectClick(index, transferId) {
objAcceptReject.index=index;
objAcceptReject.transferId=transferId;
agentStr = navigator.userAgent;
var msie = ua.indexOf("MSIE ");
if (msie > 0) // If Internet Explorer, return version number
{
var ret = window.showModalDialog("/abc.jsp?accept=false",window,"dialogHeight:175px;dialogWidth:475px;scroll:no;status:no;help:no");
if (ret=="true") {
doSomeClick(index);
}
} else if ((agentStr.indexOf("Chrome")) >- 1){
spawn(function() {
var ret = window.showModalDialog("/abcd.jsp?accept=false",window,"dialogHeight:175px;dialogWidth:475px;scroll:no;status:no;help:no");
if (ret=="true") {// create an object and store values in objects and send as parameters
doSomeClick(objAcceptReject.index);
}
});
}
else {
var ret = window.showModalDialog("/xtz.jsp?accept=false",window,"dialogHeight:175px;dialogWidth:475px;scroll:no;status:no;help:no");
if (ret=="true") {
doSomeClick(index);
}
}
My understanding is that this question is better answered over in this post.
But briefly, the answer to the OP with this method is simply:
s1 = pd.merge(df1, df2, how='inner', on=['user_id'])
Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.
You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %>
with its successor EL ${}
. They do not share the same variable scope. The allFestivals
is not available in scriptlet scope and the i
is not available in EL scope.
You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
and then iterate over the list as follows:
<c:forEach items="${allFestivals}" var="festival">
<tr>
<td>${festival.festivalName}</td>
<td>${festival.location}</td>
<td>${festival.startDate}</td>
<td>${festival.endDate}</td>
<td>${festival.URL}</td>
</tr>
</c:forEach>
(beware of possible XSS attack holes, use <c:out>
accordingly)
Don't forget to remove the <jsp:useBean>
as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml
so that you won't accidently use them:
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>true</scripting-invalid>
</jsp-property-group>
</jsp-config>

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:
String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
fis = new FileInputStream(imagefile);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);
byte[] b = baos.toByteArray();
encImage = Base64.encodeToString(b, Base64.DEFAULT);
Try with a CASE in this way :
SUM(CASE
WHEN PaymentType = "credit card"
THEN TotalAmount
ELSE 0
END) AS CreditCardTotal,
Should give what you are looking for ...
gcc
can use an assembly file as input, and invoke the assembler as needed. There is a subtlety, though:
.s
" (lowercase 's'), then gcc
calls the assembler..S
" (uppercase 'S'), then gcc
applies the C preprocessor on the source file (i.e. it recognizes directives such as #if
and replaces macros), and then calls the assembler on the result.So, on a general basis, you want to do things like this:
gcc -S file.c -o file.s
gcc -c file.s
Note Slipstream's response, that base64.b64encode

One possibility would be to use Objectify or ElementTree from the lxml module. An older version ElementTree is also available in the python xml.etree module as well. Either of these will get your xml converted to Python objects which you can then use simplejson to serialize the object to JSON.
While this may seem like a painful intermediate step, it starts making more sense when you're dealing with both XML and normal Python objects.
I had a similar need. This worked for me:
find ../../ \( -iname 'tmp' -o -iname 'vendor' \) -prune -o \( -iname '*.*rb' -o -iname '*.rjs' \) -print
Use Thread.sleep(long millis)
.
Causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds, subject to the precision and accuracy of system timers and schedulers. The thread does not lose ownership of any monitors.
One minute would be (60*1000) = 60000
milliseconds.
For example, this loop will print the current time once every 5 seconds:
try {
while (true) {
System.out.println(new Date());
Thread.sleep(5 * 1000);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
If your sleep period becomes too large for int
, explicitly compute in long
(e.g. 1000L
).
Adding to cchana's answer. The method "length-6" fails on non-latin values in enum.
For example (the values are in Cyrillic, table is UTF8 - utf8_general_ci. In the examples I use the variable for simplicity: selecting from schema gives the same):
set @a:="enum('? ??????','?? ????????','???????')";
select substring(@a,6,length(@a)-6);
+-------------------------------------------------------------+
| substring(@a,6,length(@a)-6) |
+-------------------------------------------------------------+
| '? ??????','?? ????????','???????') |
+-------------------------------------------------------------+
Note the closing parenthesis?
select right(@a,1);
+-------------+
| right(@a,1) |
+-------------+
| ) |
+-------------+
Well, let's try remove one more character:
select substring(@a,6,length(@a)-7);
+-------------------------------------------------------------+
| substring(@a,6,length(@a)-7) |
+-------------------------------------------------------------+
| '? ??????','?? ????????','???????') |
+-------------------------------------------------------------+
No luck! The parenthesis stays in place.
Checking (mid()
function works in way similar to substring()
, and both shows the same results):
select mid(@a,6,length(@a)/2);
+---------------------------------------------------------+
| mid(@a,6,length(@a)/2) |
+---------------------------------------------------------+
| '? ??????','?? ????????','?????? |
+---------------------------------------------------------+
See: the string lost only three rightmost characters. But should we replace Cyrillic with Latin, and all works just perfectly:
set @b:="enum('in use','for removal','trashed')";
select (substring(@b,6,length(@b)-6));
+----------------------------------+
| (substring(@b,6,length(@b)-6)) |
+----------------------------------+
| 'in use','for removal','trashed' |
+----------------------------------+
JFYI
Edit 20210221: the solution for non-Latin characters is CHAR_LENGTH()
instead of "simple" LENGTH()
Great question, and the answer is not a simple one. There is no "show me all .net core versions" command, but there's hope.
EDIT:
I'm not sure when it was added, but the info command now includes this information in its output. It will print out the installed runtimes and SDKs, as well as some other info:
dotnet --info
If you only want to see the SDKs: dotnet --list-sdks
If you only want to see installed runtimes: dotnet --list-runtimes
I'm on Windows, but I'd guess that would work on Mac or Linux as well with a current version.
Also, you can reference the .NET Core Download Archive to help you decipher the SDK versions.
OLDER INFORMATION: Everything below this point is old information, which is less relevant, but may still be useful.
See installed Runtimes:
Open C:\Program Files\dotnet\shared\Microsoft.NETCore.App
in Windows Explorer
See installed SDKs:
Open C:\Program Files\dotnet\sdk
in Windows Explorer
(Source for the locations: A developer's blog)
In addition, you can see the latest Runtime and SDK versions installed by issuing these commands at the command prompt:
dotnet
Latest Runtime version is the first thing listed. DISCLAIMER: This no longer works, but may work for older versions.
dotnet --version
Latest SDK version DISCLAIMER: Apparently the result of this may be affected by any global.json config files.
On macOS you could check .net core version by using below command.
ls /usr/local/share/dotnet/shared/Microsoft.NETCore.App/
On Ubuntu or Alpine:
ls /usr/share/dotnet/shared/Microsoft.NETCore.App/
It will list down the folder with installed version name.
I also ran into this issue - I was trying to pull in an object from a source and it was working in the test code but not the src code. To further test, I copied a block of code from the test and dropped it into the src code, then immediately removed the JUnit lines so I just had how the test was pulling in the object. Then suddenly my code wouldn't compile.
The issue was that when I dropped the code in, Eclipse helpfully resolved all the classes so I had JUnit calls coming from my src code, which was not proper. I should have noticed the warnings at the top about unused imports, but I neglected to see them.
Once I removed the unused JUnit imports in my src file, it all worked beautifully.
The correct way would be:
location / {
rewrite (.*) base.html last;
}
Using last
will make nginx find a new suitable location
block according to the result of rewriting.
try_files
is also a perfectly valid approach to this problem.
I discovered today that we can now debug Javascript With the developer tool bar plugins integreted in IE 8.
You can use watch, breakpoint, see the call stack etc, similarly to debuggers in professional browsers.
You can also use the statement debugger;
in your JavaScript code the set a breakpoint.
After you followed the tutorial, if your mac is not even able to run "flutter doctor", you should reboot your mac. This worked for me.
You do it exactly as you showed with this line:
get.setHeader("Content-Type", "application/x-zip");
So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.
In mysqli_query(first parameter should be connection,your sql statement) so
$connetion_name=mysqli_connect("localhost","root","","web_table") or die(mysqli_error());
mysqli_query($connection_name,'INSERT INTO web_formitem (ID, formID, caption, key, sortorder, type, enabled, mandatory, data) VALUES (105, 7, Tip izdelka (6), producttype_6, 42, 5, 1, 0, 0)');
but best practice is
$connetion_name=mysqli_connect("localhost","root","","web_table") or die(mysqli_error());
$sql_statement="INSERT INTO web_formitem (ID, formID, caption, key, sortorder, type, enabled, mandatory, data) VALUES (105, 7, Tip izdelka (6), producttype_6, 42, 5, 1, 0, 0)";
mysqli_query($connection_name,$sql_statement);
Does Customer implement the equals()
contract?
If it doesn't implement equals()
and hashCode()
, then listCustomer.contains(customer)
will check to see if the exact same instance already exists in the list (By instance I mean the exact same object--memory address, etc). If what you are looking for is to test whether or not the same Customer( perhaps it's the same customer if they have the same customer name, or customer number) is in the list already, then you would need to override equals()
to ensure that it checks whether or not the relevant fields(e.g. customer names) match.
Note: Don't forget to override hashCode()
if you are going to override equals()
! Otherwise, you might get trouble with your HashMaps and other data structures. For a good coverage of why this is and what pitfalls to avoid, consider having a look at Josh Bloch's Effective Java chapters on equals()
and hashCode()
(The link only contains iformation about why you must implement hashCode()
when you implement equals()
, but there is good coverage about how to override equals()
too).
By the way, is there an ordering restriction on your set? If there isn't, a slightly easier way to solve this problem is use a Set<Customer>
like so:
Set<Customer> noDups = new HashSet<Customer>();
noDups.addAll(tmpListCustomer);
return new ArrayList<Customer>(noDups);
Which will nicely remove duplicates for you, since Sets don't allow duplicates. However, this will lose any ordering that was applied to tmpListCustomer
, since HashSet
has no explicit ordering (You can get around that by using a TreeSet
, but that's not exactly related to your question). This can simplify your code a little bit.
This works for me
# Convert image to bytes
import PIL.Image as Image
pil_im = Image.fromarray(image)
b = io.BytesIO()
pil_im.save(b, 'jpeg')
im_bytes = b.getvalue()
return im_bytes
It's not that your file is partially downloaded. It fails authentication and hence downloads e.g "index.html" but it names it myfile.zip (since this is what you want to download).
I followed the link suggested by @thomasbabuj and figured it out eventually.
You should try adding --auth-no-challenge
and as @thomasbabuj suggested replace your password entry
I.e
wget --auth-no-challenge --user=myusername --ask-password https://test.mydomain.com/files/myfile.zip
here you go get_the_category( $post->ID );
will return the array of categories of that post you need to loop through the array
$category_detail=get_the_category('4');//$post->ID
foreach($category_detail as $cd){
echo $cd->cat_name;
}
If you do not want to use angular-ui-router, but would like to have your controllers lazy loaded via RequireJS, there are couple of problems with event $routeChangeStart
when using your controllers as RequireJS modules (lazy loaded).
You cannot be sure the controller will be loaded before $routeChangeStart
gets triggered -- in fact it wont be loaded. That means you cannot access properties of next
route like locals
or $$route
because they are not yet setup.
Example:
app.config(["$routeProvider", function($routeProvider) {
$routeProvider.when("/foo", {
controller: "Foo",
resolve: {
controller: ["$q", function($q) {
var deferred = $q.defer();
require(["path/to/controller/Foo"], function(Foo) {
// now controller is loaded
deferred.resolve();
});
return deferred.promise;
}]
}
});
}]);
app.run(["$rootScope", function($rootScope) {
$rootScope.$on("$routeChangeStart", function(event, next, current) {
console.log(next.$$route, next.locals); // undefined, undefined
});
}]);
This means you cannot check access rights in there.
Solution:
As loading of controller is done via resolve, you can do the same with your access control check:
app.config(["$routeProvider", function($routeProvider) {
$routeProvider.when("/foo", {
controller: "Foo",
resolve: {
controller: ["$q", function($q) {
var deferred = $q.defer();
require(["path/to/controller/Foo"], function(Foo) {
// now controller is loaded
deferred.resolve();
});
return deferred.promise;
}],
access: ["$q", function($q) {
var deferred = $q.defer();
if (/* some logic to determine access is granted */) {
deferred.resolve();
} else {
deferred.reject("You have no access rights to go there");
}
return deferred.promise;
}],
}
});
}]);
app.run(["$rootScope", function($rootScope) {
$rootScope.$on("$routeChangeError", function(event, next, current, error) {
console.log("Error: " + error); // "Error: You have no access rights to go there"
});
}]);
Note here that instead of using event $routeChangeStart
I'm using $routeChangeError
For me, on centOS 7 I had to remove the old pip link from /bin by
rm /bin/pip2.7
rm /bin/pip
then relink it with
sudo ln -s /usr/local/bin/pip2.7 /bin/pip2.7
Then if

Works, this should work
The specific value in your database isn't what you should be focusing on. This is likely the result of an attacker fuzzing your system to see if it is vulnerable to a set of standard attacks, instead of a targeted attack exploiting a known vulnerability.
You should instead focus on ensuring that your application is secure against these types of attacks; OWASP is a good resource for this.
If you're using parameterized queries to access the database, then you're secure against Sql injection, unless you're using dynamic Sql in the backend as well.
If you're not doing this, you're vulnerable and you should resolve this immediately.
Also, you should consider performing some sort of validation of e-mail addresses.
I assume that you've run yum upgrade. That will in general update you to the newest minor release.
Your main resources for determining the version are /etc/redhat_release
and lsb_release -a
I've tested all suggested methods plus np.array(map(f, x))
with perfplot
(a small project of mine).
Message #1: If you can use numpy's native functions, do that.
If the function you're trying to vectorize already is vectorized (like the x**2
example in the original post), using that is much faster than anything else (note the log scale):
If you actually need vectorization, it doesn't really matter much which variant you use.
Code to reproduce the plots:
import numpy as np
import perfplot
import math
def f(x):
# return math.sqrt(x)
return np.sqrt(x)
vf = np.vectorize(f)
def array_for(x):
return np.array([f(xi) for xi in x])
def array_map(x):
return np.array(list(map(f, x)))
def fromiter(x):
return np.fromiter((f(xi) for xi in x), x.dtype)
def vectorize(x):
return np.vectorize(f)(x)
def vectorize_without_init(x):
return vf(x)
perfplot.show(
setup=np.random.rand,
n_range=[2 ** k for k in range(20)],
kernels=[f, array_for, array_map, fromiter, vectorize, vectorize_without_init],
xlabel="len(x)",
)
Look at the following example code:
public class MyWorker
{
public SharedData state;
public void DoWork(SharedData someData)
{
this.state = someData;
while (true) ;
}
}
public class SharedData {
X myX;
public getX() { etc
public setX(anX) { etc
}
public class Program
{
public static void Main()
{
SharedData data = new SharedDate()
MyWorker work1 = new MyWorker(data);
MyWorker work2 = new MyWorker(data);
Thread thread = new Thread(new ThreadStart(work1.DoWork));
thread.Start();
Thread thread2 = new Thread(new ThreadStart(work2.DoWork));
thread2.Start();
}
}
In this case, the thread class MyWorker
has a variable state
. We initialise it with the same object. Now you can see that the two workers access the same SharedData object. Changes made by one worker are visible to the other.
You have quite a few remaining issues. How does worker 2 know when changes have been made by worker 1 and vice-versa? How do you prevent conflicting changes? Maybe read: this tutorial.
generating a fresh access key worked for me.
My answer is similar as Josh Greifer but generalised to sample covariance. Sample variance is just sample covariance but with the two inputs identical. This includes Bessel's correlation.
template <class Iter> typename Iter::value_type cov(const Iter &x, const Iter &y)
{
double sum_x = std::accumulate(std::begin(x), std::end(x), 0.0);
double sum_y = std::accumulate(std::begin(y), std::end(y), 0.0);
double mx = sum_x / x.size();
double my = sum_y / y.size();
double accum = 0.0;
for (auto i = 0; i < x.size(); i++)
{
accum += (x.at(i) - mx) * (y.at(i) - my);
}
return accum / (x.size() - 1);
}
Try one of:
var h = document.getElementById('someDiv').clientHeight;
var h = document.getElementById('someDiv').offsetHeight;
var h = document.getElementById('someDiv').scrollHeight;
clientHeight
includes the height and vertical padding.
offsetHeight
includes the height, vertical padding, and vertical borders.
scrollHeight
includes the height of the contained document (would be greater than just height in case of scrolling), vertical padding, and vertical borders.
This is another method I use because changing DropDownSyle
to DropDownList
makes it look 3D and sometimes its just plain ugly.
You can prevent user input by handling the KeyPress
event of the ComboBox like this.
private void ComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
Assume that you have MyPayments class like
public class Mypayment
{
public int year { get; set; }
public string month { get; set; }
public string price { get; set; }
public bool ispaid { get; set; }
}
and you have a list of MyPayments
public List<Mypayment> mypayments { get; set; }
and you want group the list by year. You can use linq like this:
List<List<Mypayment>> mypayments = (from IGrouping<int, Mypayment> item in yearGroup
let mypayments1 = (from _payment in UserProjects.mypayments
where _payment.year == item.Key
select _payment).ToList()
select mypayments1).ToList();

Second command adds s attribute which will keep new files and directories within cake having the same group permissions.
First step would be making the function object, then applying it. If you want a matrix object that has the same number of rows, you can predefine it and use the object[] form as illustrated (otherwise the returned value will be simplified to a vector):
bvnormdens <- function(x=c(0,0),mu=c(0,0), sigma=c(1,1), rho=0){
exp(-1/(2*(1-rho^2))*(x[1]^2/sigma[1]^2+
x[2]^2/sigma[2]^2-
2*rho*x[1]*x[2]/(sigma[1]*sigma[2]))) *
1/(2*pi*sigma[1]*sigma[2]*sqrt(1-rho^2))
}
out=rbind(c(1,2),c(3,4),c(5,6));
bvout<-matrix(NA, ncol=1, nrow=3)
bvout[] <-apply(out, 1, bvnormdens)
bvout
[,1]
[1,] 1.306423e-02
[2,] 5.931153e-07
[3,] 9.033134e-15
If you wanted to use other than your default parameters then the call should include named arguments after the function:
bvout[] <-apply(out, 1, FUN=bvnormdens, mu=c(-1,1), rho=0.6)
apply() can also be used on higher dimensional arrays and the MARGIN argument can be a vector as well as a single integer.
make
in, and off itself, handles directory targets just the same as file targets. So, it's easy to write rules like this:
outDir/someTarget: Makefile outDir
touch outDir/someTarget
outDir:
mkdir -p outDir
The only problem with that is, that the directories timestamp depends on what is done to the files inside. For the rules above, this leads to the following result:
$ make
mkdir -p outDir
touch outDir/someTarget
$ make
touch outDir/someTarget
$ make
touch outDir/someTarget
$ make
touch outDir/someTarget
This is most definitely not what you want. Whenever you touch the file, you also touch the directory. And since the file depends on the directory, the file consequently appears to be out of date, forcing it to be rebuilt.
However, you can easily break this loop by telling make to ignore the timestamp of the directory. This is done by declaring the directory as an order-only prerequsite:
# The pipe symbol tells make that the following prerequisites are order-only
# |
# v
outDir/someTarget: Makefile | outDir
touch outDir/someTarget
outDir:
mkdir -p outDir
This correctly yields:
$ make
mkdir -p outDir
touch outDir/someTarget
$ make
make: 'outDir/someTarget' is up to date.
TL;DR:
Write a rule to create the directory:
$(OUT_DIR):
mkdir -p $(OUT_DIR)
And have the targets for the stuff inside depend on the directory order-only:
$(OUT_DIR)/someTarget: ... | $(OUT_DIR)

I have a similar problem (at least I think it is similar). In one of the replies here the solution is as follows:
select
A.*
from
table_A A
inner join table_B B
on A.id = B.id
where
B.tag = 'chair'
That WHERE clause I would like to be:
WHERE B.tag = A.<col_name>
or, in my specific case:
WHERE B.val BETWEEN A.val1 AND A.val2
More detailed:
Table A carries status information of a fleet of equipment. Each status record carries with it a start and stop time of that status. Table B carries regularly recorded, timestamped data about the equipment, which I want to extract for the duration of the period indicated in table A.
Got an answer for this problem without using ExifInterface. We can get the rotation of the camera either front camera or back camera whichever you are using then while creating the Bitmap we can rotate the bitmap using Matrix.postRotate(degree)
public int getRotationDegree() {
int degree = 0;
for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(i, info);
if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
degree = info.orientation;
return degree;
}
}
return degree;
}
After calculating the rotation you can rotate you bitmap like below:
Matrix matrix = new Matrix();
matrix.postRotate(getRotationDegree());
Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);
Herare bm should be your bitmap.
If you want to know the rotation of your front camera just change Camera.CameraInfo.CAMERA_FACING_BACK to Camera.CameraInfo.CAMERA_FACING_FRONT above.
I hope this helps.
You can setup a default username via ~/.subversion/servers:
[groups]
yourgroupname = svn.example.com
[yourgroupname]
username = yourusername
Please be aware that older versions of svn do not support it (e.g. 1.3.1 [sic!]).
Use
find \( -path "./tmp" -o -path "./scripts" \) -prune -o -name "*_peaks.bed" -print
or
find \( -path "./tmp" -o -path "./scripts" \) -prune -false -o -name "*_peaks.bed"
or
find \( -path "./tmp" -path "./scripts" \) ! -prune -o -name "*_peaks.bed"
The order is important. It evaluates from left to right. Always begin with the path exclusion.
Do not use -not
(or !
) to exclude whole directory. Use -prune
.
As explained in the manual:
-prune The primary shall always evaluate as true; it
shall cause find not to descend the current
pathname if it is a directory. If the -depth
primary is specified, the -prune primary shall
have no effect.
and in the GNU find manual:
-path pattern
[...]
To ignore a whole
directory tree, use -prune rather than checking
every file in the tree.
Indeed, if you use -not -path "./pathname"
,
find will evaluate the expression for each node under "./pathname"
.
find expressions are just condition evaluation.
\( \)
- groups operation (you can use -path "./tmp" -prune -o -path "./scripts" -prune -o
, but it is more verbose).-path "./script" -prune
- if -path
returns true and is a directory, return true for that directory and do not descend into it.-path "./script" ! -prune
- it evaluates as (-path "./script") AND (! -prune)
. It revert the "always true" of prune to always false. It avoids printing "./script"
as a match.-path "./script" -prune -false
- since -prune
always returns true, you can follow it with -false
to do the same than !
.-o
- OR operator. If no operator is specified between two expressions, it defaults to AND operator.Hence, \( -path "./tmp" -o -path "./scripts" \) -prune -o -name "*_peaks.bed" -print
is expanded to:
[ (-path "./tmp" OR -path "./script") AND -prune ] OR ( -name "*_peaks.bed" AND print )
The print is important here because without it is expanded to:
{ [ (-path "./tmp" OR -path "./script" ) AND -prune ] OR (-name "*_peaks.bed" ) } AND print
-print
is added by find - that is why most of the time, you do not need to add it in you expression. And since -prune
returns true, it will print "./script" and "./tmp".
It is not necessary in the others because we switched -prune
to always return false.
Hint: You can use find -D opt expr 2>&1 1>/dev/null
to see how it is optimized and expanded,
find -D search expr 2>&1 1>/dev/null
to see which path is checked.
You will also get this error if you are on Windows and your project path has parenthesis in it. eg. "cordova(something)".
(At least until this issue is fixed.)

Yet another answer (in January 2018) to the old question (in January 2009).
The specification of Java properties file is described in the JavaDoc of java.util.Properties.load(java.io.Reader)
. One problem is that the specification is a bit complicated than the first impression we may have. Another problem is that some answers here arbitrarily added extra specifications - for example, ;
and '
are regarded as starters of comment lines but they should not be. Double/single quotations around property values are removed but they should not be.
The following are points to be considered.
\n
, \r
, \r\n
or the end of the stream.\
.
, \u0020
), tab (\t
, \u0009
) and form feed (\f
, \u000C
).=
is used as the separator between a key and a value.:
is used as the separator between a key and a value, too.#
or !
as its first non-white space characters, meaning leading white spaces before #
or !
are allowed.\
.=
, :
and white spaces can be embedded in a key if they are escaped by backslashes.\r
and \n
escape sequences.\uxxxx
is used to represent a Unicode character.So, for example, if test.properties
has the following content:
# A comment line that starts with '#'.
# This is a comment line having leading white spaces.
! A comment line that starts with '!'.
key1=value1
key2 : value2
key3 value3
key\
4=value\
4
\u006B\u0065\u00795=\u0076\u0061\u006c\u0075\u00655
\k\e\y\6=\v\a\lu\e\6
\:\ \= = \\colon\\space\\equal
it should be interpreted as the following key-value pairs.
+------+--------------------+
| KEY | VALUE |
+------+--------------------+
| key1 | value1 |
| key2 | value2 |
| key3 | value3 |
| key4 | value4 |
| key5 | value5 |
| key6 | value6 |
| : = | \colon\space\equal |
+------+--------------------+
PropertiesLoader
class in Authlete.Authlete NuGet package can interpret the format of the specification. The example code below:
using System;
using System.IO;
using System.Collections.Generic;
using Authlete.Util;
namespace MyApp
{
class Program
{
public static void Main(string[] args)
{
string file = "test.properties";
IDictionary<string, string> properties;
using (TextReader reader = new StreamReader(file))
{
properties = PropertiesLoader.Load(reader);
}
foreach (var entry in properties)
{
Console.WriteLine($"{entry.Key} = {entry.Value}");
}
}
}
}
will generate this output:
key1 = value1
key2 = value2
key3 = value3
key4 = value4
key5 = value5
key6 = value6
: = = \colon\space\equal
An equivalent example in Java is as follows:
import java.util.*;
import java.io.*;
public class Program
{
public static void main(String[] args) throws IOException
{
String file = "test.properties";
Properties properties = new Properties();
try (Reader reader = new FileReader(file))
{
properties.load(reader);
}
for (Map.Entry<Object, Object> entry : properties.entrySet())
{
System.out.format("%s = %s\n", entry.getKey(), entry.getValue());
}
}
}
The source code, PropertiesLoader.cs
, can be found in authlete-csharp. xUnit tests for PropertiesLoader
are written in PropertiesLoaderTest.cs
.
Another solution is Remove ng.ps1 from the directory C:\Users%username%\AppData\Roaming\npm\ and clearing the npm cache
We can use with Jquery as well as length as below example :
Suppose we have GuarantorName textbox which has value and want to get firstname and lastname- it may be null. So rathar than
var gnamesplit = $("#txtGuarantorName").val().split(" ");
var gLastName = "";
var gFirstName = "";
if(gnamesplit.length > 0 ){
gLastName = gnamesplit[0];
}
if(gnamesplit.length > 1 ){
gFirstName = gnamesplit[1];
}
We can use below code with Jquery with minimum code
_x000D_
_x000D_
var gnamesplit = $("#txtGuarantorName").val().split(" ");_x000D_
var gLastName = gnamesplit.length > 0 ? gnamesplit[0] : "";_x000D_
var gFirstName = gnamesplit.length > 1 ? gnamesplit[1] : "";_x000D_
$("#txtLastName").val(gLastName);_x000D_
$("#txtFirstName").val(gFirstName);_x000D_
_x000D_
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div >_x000D_
Guarantor Name: <input type="text" id="txtGuarantorName" value="ASP.NET Core" /><br/>_x000D_
<br/>_x000D_
<br/>_x000D_
_x000D_
First Name: <input type="text" id="txtLastName" value="ASP.NET Core" />_x000D_
Last Name: <input type="text" id="txtFirstName" value="ASP.NET Core" />_x000D_
</div>

what about this simple inArray function:
Function isInArray(ByRef stringToBeFound As String, ByRef arr As Variant) As Boolean
For Each element In arr
If element = stringToBeFound Then
isInArray = True
Exit Function
End If
Next element
End Function
In practice, monad is a custom implementation of function composition operator that takes care of side effects and incompatible input and return values (for chaining).

The Bootstrap team seems to have removed it. See here: https://github.com/twbs/bootstrap/issues/8922 . @Skelly's answer involves custom css which I didn't want to do so I used the grid system and nav-pills. It worked fine and looked great. The code looks like so:
<div class="row">
<!-- Navigation Buttons -->
<div class="col-md-3">
<ul class="nav nav-pills nav-stacked" id="myTabs">
<li class="active"><a href="#home" data-toggle="pill">Home</a></li>
<li><a href="#profile" data-toggle="pill">Profile</a></li>
<li><a href="#messages" data-toggle="pill">Messages</a></li>
</ul>
</div>
<!-- Content -->
<div class="col-md-9">
<div class="tab-content">
<div class="tab-pane active" id="home">Home</div>
<div class="tab-pane" id="profile">Profile</div>
<div class="tab-pane" id="messages">Messages</div>
</div>
</div>
</div>
You can see this in action here: http://bootply.com/81948
[Update]
@SeanK gives the option of not having to enable the nav-pills through Javascript and instead using data-toggle="pill"
. Check it out here: http://bootply.com/96067. Thanks Sean.

You can't. It's not a trusted event.
Events that are generated by the user agent, either as a result of user interaction, or as a direct result of changes to the DOM, are trusted by the user agent with privileges that are not afforded to events generated by script through the DocumentEvent.createEvent("Event") method, modified using the Event.initEvent() method, or dispatched via the EventTarget.dispatchEvent() method. The isTrusted attribute of trusted events has a value of true, while untrusted events have a isTrusted attribute value of false.
Most untrusted events should not trigger default actions, with the exception of click or DOMActivate events.
You have to add a class and add/remove that on the mouseover/mouseout events manually.
Side note, I'm answering this here after I marked this as a duplicate since no answer here really covers the issue from what I see. Hopefully, one day it'll be merged.
Just as a note you can also use this for iPads:
activityViewController.popoverPresentationController?.sourceView = sender
So the popover pops from the sender (the button in that case).

What does the UDF EntityHasProfile() do?
Typically you could do something like this with a LEFT JOIN:
SELECT EntityId, EntityName, CASE WHEN EntityProfileIs IS NULL THEN 0 ELSE 1 END AS Has Profile
FROM Entities
LEFT JOIN EntityProfiles
ON EntityProfiles.EntityId = Entities.EntityId
This should eliminate a need for a costly scalar UDF call - in my experience, scalar UDFs should be a last resort for most database design problems in SQL Server - they are simply not good performers.
I had the same issue. I started to reset the default of the column.
change_column :users, :column_name, :boolean, default: nil
change_column :users, :column_name, :integer, using: 'column_name::integer', default: 0, null: false
There is nothing wrong with returning a void @ResponseBody
and you should for POST
requests.
Use HTTP status codes to define errors within exception handler routines instead as others are mentioning success status. A normal method as you have will return a response code of 200
which is what you want, any exception handler can then return an error object and a different code (i.e. 500
).
The ADB
is now located in the Android SDK platform-tools.
[sdk directory]/platform-tools
directory and if it does not exist, then open the SDK manager in the Android Studio (a button somewhere in the top menu, android logo with a down arrow), switch to SDK tools tab and and select/install the Android SDK Platform-tools."Tools > Android SDK platform tools".
If the above does not solve the problem, try reinstalling the tools: open the "Standalone SDK manager" and uninstall the Android SDK platform-tools, delete the [your sdk directory]/platform-tools
directory completely and install it again using the SDK manager.
Check your antivirus chest. Sometimes the Antivirus program thinks adb.exe is a virus. If you find it there please restore the file and it will start working. You can also put adb.exe as a safe file in you Antivirus program.

This would do the job:
number=int(raw_input("Enter a number to see if its prime:"))
if number <= 1:
print "number is not prime"
else:
a=2
check = True
while a != number:
if number%a == 0:
print "Number is not prime"
check = False
break
a+=1
if check == True:
print "Number is prime"
Try this
typeof(IFoo).IsAssignableFrom(typeof(BarClass));
This will tell you whether BarClass(Derived)
implements IFoo(SomeType)
or not
This maybe irrelevant and of no use, but as it's javascript, you don't have to use the ternary as suggested above in the ng-click statement. You should also be able to use the lazy evaluation ("or die") syntax as well. So for your example above:
<input ng-click="{{if(profileForm.$valid) updateMyProfile()}}" name="submit" id="submit" value="Save" class="submit" type="submit">
would become:
<input ng-click="profileForm.$valid && updateMyProfile()" name="submit" id="submit" value="Save" class="submit" type="submit">
In this case, if the profile is not valid then nothing happens, otherwise, updateMyProfile() is called. Like in the link @falinsky provides above.

Error.stackTraceLimit = 100;
const A = () => {
fp = B;
}
const B = () => {
fp = A;
}
let fp = B;
const then = process.hrtime.bigint();
for(;;) {
counter++;
if (counter > max) {
const now = process.hrtime.bigint();
const nanos = now - then;
console.log({ "runtime(sec)": Number(nanos) / (1000000000.0) })
throw Error('exit')
}
fp()
continue;
}
output:

There is no .NET framework support for IMAP. You'll need to use some 3rd party component.
Try Mail.dll email component, it's very affordable and easy to use, it also supports SSL:
using(Imap imap = new Imap())

imap.ConnectSSL("imap.company.com");
imap.Login("user", "password");
imap.SelectInbox();
List<long> uids = imap.Search(Flag.Unseen);
foreach (long uid in uids)
{
string eml = imap.GetMessageByUID(uid);
IMail message = new MailBuilder()

Console.WriteLine(message.Subject);
Console.WriteLine(message.Text);

Use align-items: flex-start
on the container, or align-self: flex-start
on the flex items.
No need for display: inline-flex
.
An initial setting of a flex container is align-items: stretch
. This means that flex items will expand to cover the full length of the container along the cross axis.
The align-self
property does the same thing as align-items
, except that align-self
applies to flex items while align-items
applies to the flex container.
By default, align-self
inherits the value of align-items
.
Since your container is flex-direction: column
, the cross axis is horizontal, and align-items: stretch
is expanding the child element's width as much as it can.
You can override the default with align-items: flex-start
on the container (which is inherited by all flex items) or align-self: flex-start
on the item (which is confined to the single item).
Learn more about flex alignment along the cross axis here:

Maybe you are looking about Full Text Search.
In contrast to full-text search, the LIKE Transact-SQL predicate works on character patterns only. Also, you cannot use the LIKE predicate to query formatted binary data. Furthermore, a LIKE query against a large amount of unstructured text data is much slower than an equivalent full-text query against the same data. A LIKE query against millions of rows of text data can take minutes to return; whereas a full-text query can take only seconds or less against the same data, depending on the number of rows that are returned.
All the other answers are correct, however, you might have problems if you're trying to check directory in a user's home directory. Make sure you expand the relative path before checking:
File.exists? '~/exists'
=> false
File.directory? '~/exists'
=> false
File.exists? File.expand_path('~/exists')
=> true
Pretty easy to do this across multiple cells, without having to add '%' to each individually.
Select all the cells you want to change to percent, right Click, then format Cells, choose Custom. Type in 0.0\%

A good question! I think DATA ENCODING (sometimes a CHARSET also involved) is a MEMORY EXPRESSION MECHANISM in order to save data to a file or transfer data via a network, so I answer this question as:
1. When should I use std::wstring over std::string?
If the programming platform or API function is a single-byte one, and we want to process or parse some Unicode data, e.g read from Windows'.REG file or network 2-byte stream, we should declare std::wstring variable to easily process them. e.g.: wstring ws=L"??a"(6 octets memory: 0x4E2D 0x56FD 0x0061), we can use ws[0] to get character '?' and ws[1] to get character '?' and ws[2] to get character 'a', etc.
2. Can std::string hold the entire ASCII character set, including the special characters?
Yes. But notice: American ASCII, means each 0x00~0xFF octet stands for one character, including printable text such as "123abc&*_&" and you said special one, mostly print it as a '.' avoid confusing editors or terminals. And some other countries extend their own "ASCII" charset, e.g. Chinese, use 2 octets to stand for one character.
3.Is std::wstring supported by all popular C++ compilers?
Maybe, or mostly. I have used: VC++6 and GCC 3.3, YES
4. What is exactly a "wide character"?
a wide character mostly indicates using 2 octets or 4 octets to hold all countries' characters. 2 octet UCS2 is a representative sample, and further e.g. English 'a', its memory is 2 octet of 0x0061(vs in ASCII 'a's memory is 1 octet 0x61)
There are of course a lot of good solutions based on what you need. If it is just configuration, you should have a look at Jakarta commons-configuration and commons-digester.
You could always use the standard JDK method of getting a document :
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
[...]
File file = new File("some/path");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(file);
You should pass the object to get method of the field, so
Field field = object.getClass().getDeclaredField(fieldName);
field.setAccessible(true);
Object value = field.get(object);
new_df = df[df.C != 'XYZ']

I ran into this issue on GKE and the reason was no credentials for docker.
Running this resolved it:
gcloud auth configure-docker
For small algorithms you can use the module timeit from python documentation:
def test():
"Stupid test function"
L = []
for i in range(100):
L.append(i)
if __name__=='__main__':
from timeit import Timer
t = Timer("test()", "from __main__ import test")
print t.timeit()
Less accurately but still valid you can use module time like this:
from time import time
t0 = time()
call_mifuntion_vers_1()
t1 = time()
call_mifunction_vers_2()
t2 = time()
print 'function vers1 takes %f' %(t1-t0)
print 'function vers2 takes %f' %(t2-t1)
You have to tell the browser what you are sending back so that the browser can take appropriate action like launching a PDF viewer if its a PDF that is being received or launching a video player to play video file ,rendering the HTML if the content type is simple html response, save the bytes of the response as a downloaded file, etc.
some common MIME types are text/html,application/pdf,video/quicktime,application/java,image/jpeg,application/jar etc
In your case since you are sending HTML response to client you will have to set the content type as text/html
It's a harder problem if you need to use SSH at build time. For example if you're using git clone
, or in my case pip
and npm
to download from a private repository.
The solution I found is to add your keys using the --build-arg
flag. Then you can use the new experimental --squash
command (added 1.13) to merge the layers so that the keys are no longer available after removal. Here's my solution:
Build command
$ docker build -t example --build-arg ssh_prv_key="$(cat ~/.ssh/id_rsa)" --build-arg ssh_pub_key="$(cat ~/.ssh/id_rsa.pub)" --squash .
Dockerfile
FROM python:3.6-slim
ARG ssh_prv_key
ARG ssh_pub_key
RUN apt-get update && \
apt-get install -y \
git \
openssh-server \
libmysqlclient-dev
# Authorize SSH Host
RUN mkdir -p /root/.ssh && \
chmod 0700 /root/.ssh && \
ssh-keyscan github.com > /root/.ssh/known_hosts
# Add the keys and set permissions
RUN echo "$ssh_prv_key" > /root/.ssh/id_rsa && \
echo "$ssh_pub_key" > /root/.ssh/id_rsa.pub && \
chmod 600 /root/.ssh/id_rsa && \
chmod 600 /root/.ssh/id_rsa.pub
# Avoid cache purge by adding requirements first
ADD ./requirements.txt /app/requirements.txt
WORKDIR /app/
RUN pip install -r requirements.txt
# Remove SSH keys
RUN rm -rf /root/.ssh/
# Add the rest of the files
ADD . .
CMD python manage.py runserver
Update: If you're using Docker 1.13 and have experimental features on you can append --squash
to the build command which will merge the layers, removing the SSH keys and hiding them from docker history
.
1) In some cases, yes. If the WSDL contains things like Policies and such that direct the runtime behavior, then the WSDL may be required at runtime. Artifacts are not generated for policy related things and such. Also, in some obscure RPC/Literal cases, not all the namespaces that are needed are output in the generated code (per spec). Thus, the wsdl would be needed for them. Obscure cases though.
2) I thought something like would work. What version of CXF? That sounds like a bug. You can try an empty string in there (just spaces). Not sure if that works or not. That said, in your code, you can use the constructor that takes the WSDL URL and just pass null. The wsdl wouldn't be used.
3) Just the limitations above.
An ioctl
, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.
An alternative is the sysfs
interface, where you set up a file under /sys/
and read/write that to get information from and to the driver. An example of how to set this up:
static ssize_t mydrvr_version_show(struct device *dev,
struct device_attribute *attr, char *buf)
{
return sprintf(buf, "%s\n", DRIVER_RELEASE);
}
static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);
And during driver setup:
device_create_file(dev, &dev_attr_version);
You would then have a file for your device in /sys/
, for example, /sys/block/myblk/version
for a block driver.
Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl
or libnl3
libraries.
Both types are of course associations, and not really mapped strictly to language elements like that. The difference is in the purpose, context, and how the system is modeled.
As a practical example, compare two different types of systems with similar entities:
A car registration system that primarily keep track of cars, and their owners, etc. Here we are not interested in the engine as a separate entity, but we may still have engine related attributes, like power, and type of fuel. Here the Engine may be a composite part of the car entity.
A car service shop management system that manages car parts, servicing cars, and replace parts, maybe complete engines. Here we may even have engines stocked and need to keep track of them and other parts separately and independent of the cars. Here the Engine may be an aggregated part of the car entity.
How you implement this in your language is of minor concern since at that level things like readability is much more important.
@tableName
Table variables are alive for duration of the script running only i.e. they are only session level objects.
To test this, open two query editor windows under sql server management studio, and create table variables with same name but different structures. You will get an idea. The @tableName
object is thus temporary and used for our internal processing of data, and it doesn't contribute to the actual database structure.
There is another type of table object which can be created for temporary use. They are #tableName
objects declared like similar create statement for physical tables:
Create table #test (Id int, Name varchar(50))
This table object is created and stored in temp database. Unlike the first one, this object is more useful, can store large data and takes part in transactions etc. These tables are alive till the connection is open. You have to drop the created object by following script before re-creating it.
IF OBJECT_ID('tempdb..#test') IS NOT NULL
DROP TABLE #test
Hope this makes sense !
It looks like you want to define Truck as a Class
with properties NumberOfAxles, AxleWeights & AxleSpacings.
This can be defined in a CLASS MODULE (here named clsTrucks)
Option Explicit
Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double
Public Property Get truckID() As String
truckID = tID
End Property
Public Property Let truckID(value As String)
tID = value
End Property
Public Property Get truckNumberOfAxles() As Double
truckNumberOfAxles = tNumberOfAxles
End Property
Public Property Let truckNumberOfAxles(value As Double)
tNumberOfAxles = value
End Property
Public Property Get truckAxleSpacings() As Double
truckAxleSpacings = tAxleSpacings
End Property
Public Property Let truckAxleSpacings(value As Double)
tAxleSpacings = value
End Property
then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.
Option Explicit
Public TruckCollection As New Collection
Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long
'Add 5 trucks
For i = 1 To 5
Set tempTruck = New clsTrucks
'Random data
tempTruck.truckID = "Truck" & i
tempTruck.truckAxleSpacings = 13.5 + i
tempTruck.truckNumberOfAxles = 20.5 + i
'tempTruck.truckID is the collection key
TruckCollection.Add tempTruck, tempTruck.truckID
Next i
'retrieve 5 trucks
For i = 1 To 5
'retrieve by collection index
Debug.Print TruckCollection(i).truckAxleSpacings
'retrieve by key
Debug.Print TruckCollection("Truck" & i).truckAxleSpacings
Next i
End Sub
There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.
Here is how to use a View along with permissions to limit the columns a user can update in the table.
/* This creates the view, limiting user to only 2 columns from MyTestTable */
CREATE VIEW dbo.myTESTview
WITH SCHEMABINDING AS
SELECT ID, Quantity FROM dbo.MyTestTable;
/* This uses the view to execute an update on the table MyTestTable */
UPDATE dbo.myTESTview
SET Quantity = 7
WHERE ID = 1
Database is a collection of schemas and schema is a collection of tables. But in MySQL they use it the same way.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
And then install wget
with brew and also enable openressl
for TLS support
brew install wget --with-libressl
It worked perfectly for me.
If you are getting the output Optional(5)
when trying to print the value of 5
in an optional Int or String, you should unwrap the value first:
if let value = text {
print(value)
}
Now you've got the value without the "Optional" string that Swift adds when the value is not unwrapped before.
There are some great answers mentioned here. Another approach you could take would be to use some free SDKs available online like Atooma, tranql and Neura, that can be integrated with your Android application (it takes less than 20 min to integrate). Along with giving you the accurate location of your user, it can also give you good insights about your user’s activities. Also, some of them consume less than 1% of your battery
This is probably a rare case, but for me a library that was included in the settings.gradle was not there.
E.g. I had: include ':libraries:Android-RateThisApp:library'
in my settings.gradle
but the folder Android-RateThisApp was empty. As soon as I checked out this submodule the gradle sync succeed.
Let me share an example which I developed with BS4, thymeleaf and Spring boot.
I am using two SELECTs, where the second ("subtopic") gets filled by an AJAX call based on the selection of the first("topic").
First, the thymeleaf snippet:
<div class="form-group">
<label th:for="topicId" th:text="#{label.topic}">Topic</label>
<select class="custom-select"
th:id="topicId" th:name="topicId"
th:field="*{topicId}"
th:errorclass="is-invalid" required>
<option value="" selected
th:text="#{option.select}">Select
</option>
<optgroup th:each="topicGroup : ${topicGroups}"
th:label="${topicGroup}">
<option th:each="topicItem : ${topics}"
th:if="${topicGroup == topicItem.grp} "
th:value="${{topicItem.baseIdentity.id}}"
th:text="${topicItem.name}"
th:selected="${{topicItem.baseIdentity.id==topicId}}">
</option>
</optgroup>
<option th:each="topicIter : ${topics}"
th:if="${topicIter.grp == ''} "
th:value="${{topicIter.baseIdentity.id}}"
th:text="${topicIter.name}"
th:selected="${{topicIter.baseIdentity?.id==topicId}}">
</option>
</select>
<small id="topicHelp" class="form-text text-muted"
th:text="#{label.topic.tt}">select</small>
</div><!-- .form-group -->
<div class="form-group">
<label for="subtopicsId" th:text="#{label.subtopicsId}">subtopics</label>
<select class="custom-select"
id="subtopicsId" name="subtopicsId"
th:field="*{subtopicsId}"
th:errorclass="is-invalid" multiple="multiple">
<option value="" disabled
th:text="#{option.multiple.optional}">Select
</option>
<option th:each="subtopicsIter : ${subtopicsList}"
th:value="${{subtopicsIter.baseIdentity.id}}"
th:text="${subtopicsIter.name}">
</option>
</select>
<small id="subtopicsHelp" class="form-text text-muted"
th:unless="${#fields.hasErrors('subtopicsId')}"
th:text="#{label.subtopics.tt}">select</small>
<small id="subtopicsIdError" class="invalid-feedback"
th:if="${#fields.hasErrors('subtopicsId')}"
th:errors="*{subtopicsId}">Errors</small>
</div><!-- .form-group -->
I am iterating over a list of topics that is stored in the model context, showing all groups with their topics, and after that all topics that do not have a group. BaseIdentity is an @Embedded composite key BTW.
Now, here's the jQuery that handles changes:
$('#topicId').change(function () {
selectedOption = $(this).val();
if (selectedOption === "") {
$('#subtopicsId').prop('disabled', 'disabled').val('');
$("#subtopicsId option").slice(1).remove(); // keep first
} else {
$('#subtopicsId').prop('disabled', false)
var orig = $(location).attr('origin');
var url = orig + "/getsubtopics/" + selectedOption;
$.ajax({
url: url,
success: function (response) {
var len = response.length;
$("#subtopicsId option[value!='']").remove(); // keep first
for (var i = 0; i < len; i++) {
var id = response[i]['baseIdentity']['id'];
var name = response[i]['name'];
$("#subtopicsId").append("<option value='" + id + "'>" + name + "</option>");
}
},
error: function (e) {
console.log("ERROR : ", e);
}
});
}
}).change(); // and call it once defined
The initial call of change() makes sure it will be executed on page re-load or if a value has been preselected by some initialization in the backend.
BTW: I am using "manual" form validation (see "is-valid"/"is-invalid"), because I (and users) didn't like that BS4 marks non-required empty fields as green. But that's byond scope of this Q and if you are interested then I can post it also.
my.data.frame <- subset(data , V1 > 2 | V2 < 4)
An alternative solution that mimics the behavior of this function and would be more appropriate for inclusion within a function body:
new.data <- data[ which( data$V1 > 2 | data$V2 < 4) , ]
Some people criticize the use of which
as not needed, but it does prevent the NA
values from throwing back unwanted results. The equivalent (.i.e not returning NA-rows for any NA's in V1 or V2) to the two options demonstrated above without the which
would be:
new.data <- data[ !is.na(data$V1 | data$V2) & ( data$V1 > 2 | data$V2 < 4) , ]
Note: I want to thank the anonymous contributor that attempted to fix the error in the code immediately above, a fix that got rejected by the moderators. There was actually an additional error that I noticed when I was correcting the first one. The conditional clause that checks for NA values needs to be first if it is to be handled as I intended, since ...
> NA & 1
[1] NA
> 0 & NA
[1] FALSE
Order of arguments may matter when using '&".
if (Control.ModifierKeys == Keys.Shift)
//Shift is pressed
The cursor x/y position is a property, and a keypress (like a mouse click/mousemove) is an event. Best practice is usually to let the interface be event driven. About the only time you would need the above is if you're trying to do a shift + mouseclick thing.
Instead of navigating through the commits, you can also hit the y key (Github Help, Keyboard Shortcuts) to get the "permalink" for the current revision / commit.
This will change the URL from https://github.com/<user>/<repository>
(master / HEAD) to https://github.com/<user>/<repository>/tree/<commit id>
.
In order to download the specific commit, you'll need to reload the page from that URL, so the Clone or Download
button will point to the "snapshot" https://github.com/<user>/<repository>/archive/<commit id>.zip
instead of the latest https://github.com/<user>/<repository>/archive/master.zip
.
If you must do this, you can check the user agent string in JavaScript:
var isIE10 = !!navigator.userAgent.match(/MSIE 10/);
As other people have mentioned, I'd always recommend feature detection instead.
Use a json array, in the format:
[
{"ID":"12345","Timestamp":"20140101", "Usefulness":"Yes",
"Code":[{"event1":"A","result":"1"},…]},
{"ID":"1A35B","Timestamp":"20140102", "Usefulness":"No",
"Code":[{"event1":"B","result":"1"},…]},
{"ID":"AA356","Timestamp":"20140103", "Usefulness":"No",
"Code":[{"event1":"B","result":"0"},…]},
...
]
Then import it into your python code
import json
with open('file.json') as json_file:
data = json.load(json_file)
Now the content of data is an array with dictionaries representing each of the elements.
You can access it easily, i.e:
data[0]["ID"]
It should be noted that you can export a variable and later change the value. The variable's changed value will be available to child processes. Once export has been set for a variable you must do export -n <var>
to remove the property.
$ K=1
$ export K
$ K=2
$ bash -c 'echo ${K-unset}'
2
$ export -n K
$ bash -c 'echo ${K-unset}'
unset
I was trying to install nginx
from here - http://nginx.org/en/docs/windows.html
Going to http://localhost/ will show something, at least a proper "not found" message
This is because 80 is the default port, and it was taken by other processes.
Now run below command:
net stop http
// Above command stopped below services
// - SSDP Discovery
// - Print Spooler
// - BranchCache
// - Function Discovery Resource Publication
// - Function Discovery Provider Host
Now, going to http://localhost/ will fail with a broken link page message.
Main process was BranchCache
This process, after stopped, will restart in a few seconds.
So we need to run other commands we need soon, an example below:
// this will stop
net stop http
// immeidately run other command you want to
start nginx
Now, going to http://localhost/ gave me:
Welcome to nginx!
Hope that helps.
In addition to @Ceki 's answer, If you are using logback and setup a config file in your project (usually logback.xml), you can define the log to plot the stack trace as well using
<encoder>
<pattern>%date |%-5level| [%thread] [%file:%line] - %msg%n%ex{full}</pattern>
</encoder>
the %ex in pattern is what makes the difference
Updated You have to change the package name to your desired package name in these five location.
1.) src/profile/AndroidManifest.xml
2.) src/debug/AndroidManifest.xml
3.) src/main/AdroidManifest.xml
4.) build.gradle .
defaultConfig {
applicationId
5.) MainActivity.java on "package"
last step is to run flutter clean
You can edit /etc/paths. Here is mine:
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
Then add a symlink for the python version. In my case
$ cd /usr/local/bin
$ ln -s python3 python
Voila!

DotNetCoders has a starter article on it: http://www.dotnetcoders.com/web/Articles/ShowArticle.aspx?article=50. They talk about how to set up the switches in the configuration file and how to write the code, but it is pretty old (2002).
There's another article on CodeProject: A Treatise on Using Debug and Trace classes, including Exception Handling, but it's the same age.

using the WITH clause, in conjuction with GRANT USAGE
(no privileges added) or GRANT ALL
, you can also specify GRANT USAGE

I too have been through this pain - if the query is dynamically generated (e.g. Hibernate Criteria) then I couldn't find a practical way to do it.
The good news for me was that I was only investigating union to solve a performance problem when using an 'or' in an Oracle database.
The solution Patrick posted (combining the results programmatically using a set) while ugly (especially since I wanted to do results paging as well) was adequate for me.
You don't have to define operator<
for your class, actually. You can also make a comparator function object class for it, and use that to specialize std::map
. To extend your example:
struct Class1Compare
{
bool operator() (const Class1& lhs, const Class1& rhs) const
{
return lhs.id < rhs.id;
}
};
std::map<Class1, int, Class1Compare> c2int;
It just so happens that the default for the third template parameter of std::map
is std::less
, which will delegate to operator<
defined for your class (and fail if there is none). But sometimes you want objects to be usable as map keys, but you do not actually have any meaningful comparison semantics, and so you don't want to confuse people by providing operator<
on your class just for that. If that's the case, you can use the above trick.
Yet another way to achieve the same is to specialize std::less
:
namespace std
{
template<> struct less<Class1>
{
bool operator() (const Class1& lhs, const Class1& rhs) const
{
return lhs.id < rhs.id;
}
};
}
The advantage of this is that it will be picked by std::map
"by default", and yet you do not expose operator<
to client code otherwise.
Just add click event by jquery in $(document).ready() like :
$(document).ready(function(){
$('#YourControlID').click(function(){

showType:'fade',
style:{
right:'',
bottom:''
}
});
}
});
});
This is a headbreaker for a long time. I see now it's OSX.. i change it system-wide and it works perfect
When i add this the LANG in Centos6 and Fedora is also my preferred LANG. You can also "uncheck" export or set locale in terminal settings (OSX) /etc/profile
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
Use boost::algorithm::ends_with
(see e.g. http://www.boost.org/doc/libs/1_34_0/doc/html/boost/algorithm/ends_with.html ):

// works with const char*
assert(boost::algorithm::ends_with("mystring", "ing"));
// also works with std::string
std::string haystack("mystring");
std::string needle("ing");
assert(boost::algorithm::ends_with(haystack, needle));
std::string haystack2("ng");
assert(! boost::algorithm::ends_with(haystack2, needle));
You need to assign $first and $second
$first = $_POST['first'];
$second= $_POST['second'];
Also, As Travesty3 said, you need to do your arithmetic outside of the quotes:
echo $first + $second;
There is no character encoded for use as a pause symbol, though various characters or combinations of characters may look more or less like a pause symbol, depending on font.
In a discussion in the public Unicode mailing list in 2005, a suggestion was made to use two copies of the U+275A HEAVY VERTICAL BAR character: ??. But the adequacy of the result depends on font; for example, the glyph might have been designed so that the bars are too much apart. – The list discussion explains why a pause symbol had not been encoded, and this has not changed.
Thus, the best option is to use an image. If you need to use the symbol in text, it is best to create it in a suitably large size (say 60 by 60 pixels) and scale it down to text size with CSS (e.g., setting height: 0.8em
on the img
element).

The other answers have mentioned the private/public defaults, (but note that a struct is a class is a struct; they are not two different items, just two ways of defining the same item).
What might be interesting to note (particularly since the asker is likely to be using MSVC++ since he mentions "unmanaged" C++) is that Visual C++ complains under certain circumstances if a class is declared with class
and then defined with struct
(or possibly the other way round), although the standard says that is perfectly legal.

As @PavelAnossov answered, the canonical answer, use the word_tokenize
function in nltk:
from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)
If your sentence is truly simple enough:
Using the string.punctuation
set, remove punctuation then split using the whitespace delimiter:
import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y
If you can use ansible, and set the sudo rights in it, then you can easily use this script. If you're wanting to script something like this, it means you need to do it on more than one system. Therefore, you should try to automate that as well.

Another problem with your code is "

block. You should mix '

(class='headingDetail'
).
If content
did support HTML you could end up in an infinite loop where content

Although nesting isn't really how you should treat a component state, sometimes for something easy for single tier nesting.
For a state like this
state = {
contact: {
phone: '888-888-8888',
email: '[email protected]'
}
address: {
street:''
},
occupation: {
}
}
A re-useable method ive used would look like this.
handleChange = (obj) => e => {
let x = this.state[obj];
x[e.target.name] = e.target.value;
this.setState({ [obj]: x });
};
then just passing in the obj name for each nesting you want to address...
<TextField
name="street"
onChange={handleChange('address')}
/>
Structure your code so that all your temporary objects are located inside closures instead of global namespace / global object properties and go out of scope when you've done with them. GC will take care of the rest.
Be warned, the majority of the mathematically calculated examples have a hard limit of 2038-01-18
dates and will not work with fictional dates.
As there was a lack of DateTime
and DateInterval
based examples, I wanted to provide a multi-purpose function that satisfies the OP's need and others wanting compound elapsed periods, such as 1 month 2 days ago
. Along with a bunch of other use cases, such as a limit to display the date instead of the elapsed time, or to filter out portions of the elapsed time result.
Additionally the majority of the examples assume elapsed is from the current time, where the below function allows for it to be overridden with the desired end date.
/**
* multi-purpose function to calculate the time elapsed between $start and optional $end
* @param string|null $start the date string to start calculation
* @param string|null $end the date string to end calculation
* @param string $suffix the suffix string to include in the calculated string
* @param string $format the format of the resulting date if limit is reached or no periods were found
* @param string $separator the separator between periods to use when filter is not true
* @param null|string $limit date string to stop calculations on and display the date if reached - ex: 1 month
* @param bool|array $filter false to display all periods, true to display first period matching the minimum, or array of periods to display ['year', 'month']
* @param int $minimum the minimum value needed to include a period
* @return string
*/
function elapsedTimeString($start, $end = null, $limit = null, $filter = true, $suffix = 'ago', $format = 'Y-m-d', $separator = ' ', $minimum = 1)
{
$dates = (object) array(
'start' => new DateTime($start ? : 'now'),
'end' => new DateTime($end ? : 'now'),
'intervals' => array('y' => 'year', 'm' => 'month', 'd' => 'day', 'h' => 'hour', 'i' => 'minute', 's' => 'second'),
'periods' => array()
);
$elapsed = (object) array(
'interval' => $dates->start->diff($dates->end),
'unknown' => 'unknown'
);
if ($elapsed->interval->invert === 1) {
return trim('0 seconds ' . $suffix);
}
if (false === empty($limit)) {
$dates->limit = new DateTime($limit);
if (date_create()->add($elapsed->interval) > $dates->limit) {
return $dates->start->format($format) ? : $elapsed->unknown;
}
}
if (true === is_array($filter)) {
$dates->intervals = array_intersect($dates->intervals, $filter);
$filter = false;
}
foreach ($dates->intervals as $period => $name) {
$value = $elapsed->interval->$period;
if ($value >= $minimum) {
$dates->periods[] = vsprintf('%1$s %2$s%3$s', array($value, $name, ($value !== 1 ? 's' : '')));
if (true === $filter) {
break;
}
}
}
if (false === empty($dates->periods)) {
return trim(vsprintf('%1$s %2$s', array(implode($separator, $dates->periods), $suffix)));
}
return $dates->start->format($format) ? : $elapsed->unknown;
}
One thing to note - the retrieved intervals for the supplied filter values do not carry over to the next period. The filter merely displays the resulting value of the supplied periods and does not recalculate the periods to display only the desired filter total.
Usage
For the OP's need of displaying the highest period (as of 2015-02-24).
echo elapsedTimeString('2010-04-26');
/** 4 years ago */
To display compound periods and supply a custom end date (note the lack of time supplied and fictional dates).
echo elapsedTimeString('1920-01-01', '2500-02-24', null, false);
/** 580 years 1 month 23 days ago */
To display the result of filtered periods (ordering of array doesn't matter).
echo elapsedTimeString('2010-05-26', '2012-02-24', null, ['month', 'year']);
/** 1 year 8 months ago */
To display the start date in the supplied format (default Y-m-d) if the limit is reached.
echo elapsedTimeString('2010-05-26', '2012-02-24', '1 year');
/** 2010-05-26 */
There are bunch of other use cases. It can also easily be adapted to accept unix timestamps and/or DateInterval objects for the start, end, or limit arguments.
Use the Ctrl+Space
shortcut for getting all possible autocomplete options available in a particular context in the editor.
Auto Complete will also allow you to insert custom code templates into the editor, with placeholders for various inputs. For instance, attempting to auto complete the word "test" in a Java editor, in the context of a class body, will allow you to create a unit test that uses JUnit; you'll have to code the body of the method though. Some code templates like the former, come out of the box.

and you expect to see relevant members that can be accessed, the auto completion list will automatically popup with the appropriate members, on this trigger.Using function Find is cleaner way.
MyClass item = MyList.Find(item => item.name == "foo");
if (item != null) // check item isn't null
{

}
It's quite easy for a fix.
For me, we had more than one inputs in the form. We need to isolate the input / line causing error and simply add the name
attribute. That fixed the issue for me:
Before:
<form class="example-form">
<mat-form-field appearance="outline">
<mat-select placeholder="Select your option" [(ngModel)]="sample.stat"> <!--HERE -->
<mat-option *ngFor="let option of actions" [value]="option">{{option}</mat-option>
</mat-select>
</mat-form-field>
<mat-form-field appearance="outline">
<mat-label>Enter number</mat-label>
<input id="myInput" type="text" placeholder="Enter number" aria-label="Number"
matInput [formControl]="myFormControl" required [(ngModel)]="number"> <!--HERE -->
</mat-form-field>
<mat-checkbox [(ngModel)]="isRight">Check!</mat-checkbox> <!--HERE -->
</form>
After:
i just added the name
attribute for select
and checkbox
and that fixed the issue. As follows:
<mat-select placeholder="Select your option" name="mySelect"
[(ngModel)]="sample.stat"> <!--HERE: Observe the "name" attribute -->
<input id="myInput" type="text" placeholder="Enter number" aria-label="Number"
matInput [formControl]="myFormControl" required [(ngModel)]="number"> <!--HERE -->
<mat-checkbox name="myCheck" [(ngModel)]="isRight">Check!</mat-checkbox> <!--HERE: Observe the "name" attribute -->
As you see added the name
attribute. It is not necessary to be given same as your ngModel
name. Just providing the name
attribute will fix the issue.
You can set min-width property of CSS for body tag. Since this property is not supported by IE6, you can write like:
body{
min-width:1000px; /* Suppose you want minimum width of 1000px */
width: auto !important; /* Firefox will set width as auto */
width:1000px; /* As IE6 ignores !important it will set width as 1000px; */
}
Or:
body{
min-width:1000px; // Suppose you want minimum width of 1000px
_width: expression( document.body.clientWidth > 1000 ? "1000px" : "auto" ); /* sets max-width for IE6 */
}

You can do this using jQuery:
This method gets a list of its children then counts the length of that list, as simple as that.
$("ul").find("*").length;
The find() method traverses DOM downwards along descendants, all the way down to the last descendant.
Note: children() method traverses a single level down the DOM tree.
You can achieve what you are trying to do, using a Stored Procedure
which returns a query result. Views

ASCII and Unicode are two character encodings. Basically, they are standards on how to represent difference characters in binary so that they can be written, stored, transmitted, and read in digital media. The main difference between the two is in the way they encode the character and the number of bits that they use for each. ASCII originally used seven bits to encode each character. This was later increased to eight with Extended ASCII to address the apparent inadequacy of the original. In contrast, Unicode uses a variable bit encoding program where you can choose between 32, 16, and 8-bit encodings. Using more bits lets you use more characters at the expense of larger files while fewer bits give you a limited choice but you save a lot of space. Using fewer bits (i.e. UTF-8 or ASCII) would probably be best if you are encoding a large document in English.
One of the main reasons why Unicode was the problem arose from the many non-standard extended ASCII programs. Unless you are using the prevalent page, which is used by Microsoft and most other software companies, then you are likely to encounter problems with your characters appearing as boxes. Unicode virtually eliminates this problem as all the character code points were standardized.
Another major advantage of Unicode is that at its maximum it can accommodate a huge number of characters. Because of this, Unicode currently contains most written languages and still has room for even more. This includes typical left-to-right scripts like English and even right-to-left scripts like Arabic. Chinese, Japanese, and the many other variants are also represented within Unicode. So Unicode won’t be replaced anytime soon.
In order to maintain compatibility with the older ASCII, which was already in widespread use at the time, Unicode was designed in such a way that the first eight bits matched that of the most popular ASCII page. So if you open an ASCII encoded file with Unicode, you still get the correct characters encoded in the file. This facilitated the adoption of Unicode as it lessened the impact of adopting a new encoding standard for those who were already using ASCII.
Summary:
1.ASCII uses an 8-bit encoding while Unicode uses a variable bit encoding.
2.Unicode is standardized while ASCII isn’t.
3.Unicode represents most written languages in the world while ASCII does not.
4.ASCII has its equivalent within Unicode.
The ngRoute module is no longer part of the core angular.js
file. If you are continuing to use $routeProvider then you will now need to include angular-route.js
in your HTML:
<script src="angular.js">
<script src="angular-route.js">
You also have to add ngRoute
as a dependency for your application:
var app = angular.module('MyApp', ['ngRoute', ...]);
If instead you are planning on using angular-ui-router
or the like then just remove the $routeProvider
dependency from your module .config()
and substitute it with the relevant provider of choice (e.g. $stateProvider
). You would then use the ui.router
dependency:
var app = angular.module('MyApp', ['ui.router', ...]);
I had the same problem while installing scipy-0.17.0-cp35-none-win_amd64.whl and my Python version is 3.5. It returned the same error message:
scipy-0.17.0-cp35-none-win_amd64.whl is not supported wheel on this platform.
I realized that amd64 is not about my Windows, but about the Python version. Actually I am using a 32 bit Python on a 64 bit Windows. Installing the following file solved the issue:
scipy-0.17.0-cp35-none-win32.whl

Also not directly relevant to the OP, but failing to restart a PyCharm Python console, after adding a new object to a module, is also a great way to get a very confusing ImportError: Cannot import name ...
The confusing part is that PyCharm will autocomplete the import in the console, but the import then fails.

you can add security provider by editing java.security by adding security.provider.=org.bouncycastle.jce.provider.BouncyCastleProvider
or add a line in your top of your class
Security.addProvider(new BouncyCastleProvider());
you can use below line to specify provider while specifying algorithms
Cipher cipher = Cipher.getInstance("AES", "SunJCE");
if you are using other provider like Bouncy Castle then
Cipher cipher = Cipher.getInstance("AES", "BC");
An INNER JOIN
can return data from the columns from both tables, and can duplicate values of records on either side have more than one match. A LEFT SEMI JOIN
can only return columns from the left-hand table, and yields one of each record from the left-hand table where there is one or more matches in the right-hand table (regardless of the number of matches). It's equivalent to (in standard SQL):
SELECT name
FROM table_1 a
WHERE EXISTS(
SELECT * FROM table_2 b WHERE (a.name=b.name))
If there are multiple matching rows in the right-hand column, an INNER JOIN
will return one row for each match on the right table, while a LEFT SEMI JOIN
only returns the rows from the left table, regardless of the number of matching rows on the right side. That's why you're seeing a different number of rows in your result.
I am trying to get the names within table_1 that only appear in table_2.
Then a LEFT SEMI JOIN
is the appropriate query to use.
I just ran into this issue and after an hour of screwing around realized I had added an aspx file to my product that had the same name as one of my Linq-To-Sql classes.

You could check with:

this will check for the Named property
You can also achieve this using the backreference technique
sed -i.bak 's/\(.*\)/\1:80/' foo.txt
You can also use with awk like this
awk '{print $0":80"}' foo.txt > tmp && mv tmp foo.txt
I am a bit extending provided answers (since so far they concentrate on their "own"/artificial terminology focusing on programming a particular language instead of taking care of the bigger picture behind the scene of creating the programming languages, in general, i.e. when things like type-safety vs. memory considerations make the difference):
int is not boolean
Consider
boolean bar = true;
System.out.printf("Bar is %b\n", bar);
System.out.printf("Bar is %d\n", (bar)?1:0);
int baz = 1;
System.out.printf("Baz is %d\n", baz);
System.out.printf("Baz is %b\n", baz);
with output
Bar is true
Bar is 1
Baz is 1
Baz is true
Java code on 3rd line (bar)?1:0
illustrates that bar (boolean) cannot be implicitly converted (casted) into an int. I am bringing this up not to illustrate the details of implementation behind JVM, but to point out that in terms of low level considerations (as memory size) one does have to prefer values over type safety. Especially if that type safety is not truly/fully used as in boolean types where checks are done in form of
if value \in {0,1} then cast to boolean type, otherwise throw an exception.
All just to state that {0,1} < {-2^31, .. , 2^31 -1}. Seems like an overkill, right? Type safety is truly important in user defined types, not in implicit casting of primitives (although last are included in the first).
Bytes are not types or bits
Note that in memory your variable from range of {0,1} will still occupy at least a byte or a word (xbits depending on the size of the register) unless specially taken care of (e.g. packed nicely in memory - 8 "boolean" bits into 1 byte - back and forth).
By preferring type safety (as in putting/wrapping value into a box of a particular type) over extra value packing (e.g. using bit shifts or arithmetic), one does effectively chooses writing less code over gaining more memory. (On the other hand one can always define a custom user type which will facilitate all the conversion not worth than Boolean).
keyword vs. type
Finally, your question is about comparing keyword vs. type. I believe it is important to explain why or how exactly you will get performance by using/preferring keywords ("marked" as primitive) over types (normal composite user-definable classes using another keyword class) or in other words
boolean foo = true;
vs.
Boolean foo = true;
The first "thing" (type) can not be extended (subclassed) and not without a reason. Effectively Java terminology of primitive and wrapping classes can be simply translated into inline value (a LITERAL or a constant that gets directly substituted by compiler whenever it is possible to infer the substitution or if not - still fallback into wrapping the value).
Optimization is achieved due to trivial:
"Less runtime casting operations => more speed."
That is why when the actual type inference is done it may (still) end up in instantiating of wrapping class with all the type information if necessary (or converting/casting into such).
So, the difference between boolean and Boolean is exactly in Compilation and Runtime (a bit far going but almost as instanceof vs. getClass()).
Finally, autoboxing is slower than primitives
Note the fact that Java can do autoboxing is just a "syntactic sugar". It does not speed up anything, just allows you to write less code. That's it. Casting and wrapping into type information container is still performed. For performance reasons choose arithmetics which will always skip extra housekeeping of creating class instances with type information to implement type safety. Lack of type safety is the price you pay to gain performance. For code with boolean-valued expressions type safety (when you write less and hence implicit code) would be critical e.g. for if-then-else flow controls.
Not much mention of unannotated tags vs annotated ones here. 'describe' works on annotated tags and ignores unannotated ones.
This is ugly but does the job requested and it will not find any tags on other branches (and not on the one specified in the command: master in the example below)
The filtering should prob be optimized (consolidated), but again, this seems to the the job.
git log --decorate --tags master |grep '^commit'|grep 'tag:.*)$'|awk '{print $NF}'|sed 's/)$//'|head -n 1
Critiques welcome as I am going now to put this to use :)
If you add helper fields to the coordinates table, you can improve response time of the query.
Like this:
CREATE TABLE `Coordinates` (
`id` INT(10) UNSIGNED NOT NULL COMMENT 'id for the object',
`type` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'type',
`sin_lat` FLOAT NOT NULL COMMENT 'sin(lat) in radians',
`cos_cos` FLOAT NOT NULL COMMENT 'cos(lat)*cos(lon) in radians',
`cos_sin` FLOAT NOT NULL COMMENT 'cos(lat)*sin(lon) in radians',
`lat` FLOAT NOT NULL COMMENT 'latitude in degrees',
`lon` FLOAT NOT NULL COMMENT 'longitude in degrees',
INDEX `lat_lon_idx` (`lat`, `lon`)
)
If you're using TokuDB, you'll get even better performance if you add clustering indexes on either of the predicates, for example, like this:
alter table Coordinates add clustering index c_lat(lat);
alter table Coordinates add clustering index c_lon(lon);
You'll need the basic lat and lon in degrees as well as sin(lat) in radians, cos(lat)*cos(lon) in radians and cos(lat)*sin(lon) in radians for each point. Then you create a mysql function, smth like this:
CREATE FUNCTION `geodistance`(`sin_lat1` FLOAT,
`cos_cos1` FLOAT, `cos_sin1` FLOAT,
`sin_lat2` FLOAT,
`cos_cos2` FLOAT, `cos_sin2` FLOAT)
RETURNS float
LANGUAGE SQL
DETERMINISTIC
CONTAINS SQL
SQL SECURITY INVOKER
BEGIN
RETURN acos(sin_lat1*sin_lat2 + cos_cos1*cos_cos2 + cos_sin1*cos_sin2);
END
This gives you the distance.
Don't forget to add an index on lat/lon so the bounding boxing can help the search instead of slowing it down (the index is already added in the CREATE TABLE query above).
INDEX `lat_lon_idx` (`lat`, `lon`)
Given an old table with only lat/lon coordinates, you can set up a script to update it like this: (php using meekrodb)
$users = DB::query('SELECT id,lat,lon FROM Old_Coordinates');
foreach ($users as $user)
{
$lat_rad = deg2rad($user['lat']);
$lon_rad = deg2rad($user['lon']);
DB::replace('Coordinates', array(
'object_id' => $user['id'],
'object_type' => 0,
'sin_lat' => sin($lat_rad),
'cos_cos' => cos($lat_rad)*cos($lon_rad),
'cos_sin' => cos($lat_rad)*sin($lon_rad),
'lat' => $user['lat'],
'lon' => $user['lon']
));
}
Then you optimize the actual query to only do the distance calculation when really needed, for example by bounding the circle (well, oval) from inside and outside. For that, you'll need to precalculate several metrics for the query itself:
// assuming the search center coordinates are $lat and $lon in degrees
// and radius in km is given in $distance
$lat_rad = deg2rad($lat);
$lon_rad = deg2rad($lon);
$R = 6371; // earth's radius, km
$distance_rad = $distance/$R;
$distance_rad_plus = $distance_rad * 1.06; // ovality error for outer bounding box
$dist_deg_lat = rad2deg($distance_rad_plus); //outer bounding box
$dist_deg_lon = rad2deg($distance_rad_plus/cos(deg2rad($lat)));
$dist_deg_lat_small = rad2deg($distance_rad/sqrt(2)); //inner bounding box
$dist_deg_lon_small = rad2deg($distance_rad/cos(deg2rad($lat))/sqrt(2));
Given those preparations, the query goes something like this (php):
$neighbors = DB::query("SELECT id, type, lat, lon,
geodistance(sin_lat,cos_cos,cos_sin,%d,%d,%d) as distance
FROM Coordinates WHERE
lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d
HAVING (lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d) OR distance <= %d",
// center radian values: sin_lat, cos_cos, cos_sin
sin($lat_rad),cos($lat_rad)*cos($lon_rad),cos($lat_rad)*sin($lon_rad),
// min_lat, max_lat, min_lon, max_lon for the outside box
$lat-$dist_deg_lat,$lat+$dist_deg_lat,
$lon-$dist_deg_lon,$lon+$dist_deg_lon,
// min_lat, max_lat, min_lon, max_lon for the inside box
$lat-$dist_deg_lat_small,$lat+$dist_deg_lat_small,
$lon-$dist_deg_lon_small,$lon+$dist_deg_lon_small,
// distance in radians
$distance_rad);
EXPLAIN on the above query might say that it's not using index unless there's enough results to trigger such. The index will be used when there's enough data in the coordinates table. You can add FORCE INDEX (lat_lon_idx) to the SELECT to make it use the index with no regards to the table size, so you can verify with EXPLAIN that it is working correctly.
With the above code samples you should have a working and scalable implementation of object search by distance with minimal error.
You can try this: By Using Authentication Object from Spring we can get User details from it in the controller method . Below is the example , by passing Authentication object in the controller method along with argument.Once user is authenticated the details are populated in the Authentication Object.

I have read several articles discouraging inheritance in projects (as opposed to libraries/frameworks), and encouraging to program agaisnt interfaces, no against implementations.
They also advocate OO by composition: if you need the functions in class a and b, make c having members/fields of this type:
class C
{
private $a, $b;
public function __construct($x, $y)
{
$this->a = new A(42, $x);
$this->b = new B($y);
}
protected function DoSomething()
{
$this->a->Act();
$this->b->Do();
}
}
One of the simple solution to speed up your npm install is to spin up a high powered machine on AWS and use that to compile your project and ship the code back to you.
I was experimenting with it and I found that there was a very high decrease in the time to run npm install. I found a tool to execute the above command easily https://stormyapp.com
If you want to get complete ContainerId based on Container name then use following command

Hadoop comes with a useful program called distcp
for copying large amounts of data to and from Hadoop Filesystems in parallel. The canonical use case for distcp is for transferring data between two HDFS clusters.
If the clusters are running identical versions of hadoop, then the hdfs scheme is appropriate to use.
$ hadoop distcp hdfs://namenode1/foo hdfs://namenode2/bar
The data in /foo
directory of namenode1 will be copied to /bar directory of namenode2. If the /bar
directory does not exist, it will create it. Also we can mention multiple source paths.
Similar to rsync
command, distcp command by default will skip the files that already exist. We can also use -overwrite
option to overwrite the existing files in destination directory. The option -update
will only update the files that have changed.
$ hadoop distcp -update hdfs://namenode1/foo hdfs://namenode2/bar/foo
distcp
can also be implemented as a MapReduce job where the work of copying is done by the maps that run in parallel across the cluster. There will be no reducers.
If trying to copy data between two HDFS clusters that are running different versions, the copy will process will fail, since the RPC systems are incompatible. In that case we need to use the read-only HTTP based HFTP filesystems to read from the source. Here the job has to run on destination cluster.
$ hadoop distcp hftp://namenode1:50070/foo hdfs://namenode2/bar
50070 is the default port number for namenode's embedded web server.

If you are NOT on Ubuntu and you have the same problem (and you wanted to start a new topic on SO and SO suggested to have a look at this question) you can also do it like this:
Things You'll Need:
* Full Version of Adobe Acrobat
Open all the .pdf files you wish to merge. These can be minimized on your desktop as individual tabs.
Pull up what you wish to be the first page of your merged document.
Click the 'Combine Files' icon on the top left portion of the screen.
The 'Combine Files' window that pops up is divided into three sections. The first section is titled, 'Choose the files you wish to combine'. Select the 'Add Open Files' option.
Select the other open .pdf documents on your desktop when prompted.
Rearrange the documents as you wish in the second window, titled, 'Arrange the files in the order you want them to appear in the new PDF'
The final window, titled, 'Choose a file size and conversion setting' allows you to control the size of your merged PDF document. Consider the purpose of your new document. If its to be sent as an e-mail attachment, use a low size setting. If the PDF contains images or is to be used for presentation, choose a high setting. When finished, select 'Next'.
A final choice: choose between either a single PDF document, or a PDF package, which comes with the option of creating a specialized cover sheet. When finished, hit 'Create', and save to your preferred location.
Double check the PDF documents prior to merging to make sure all pertinent information is included. Its much easier to re-create a single PDF page than a multi-page document.
Any searching with select statement yield you only object name, where search keyword contains. Easiest and efficient way is get script of procedure/function and then search in generated text file, I also follows this technique :) So you are exact pinpoint.
There are only 4 kinds:
NULL
for each value in the table on the right. This means that every row from the table on the left will appear at least once in the output. A "cross join" or "cartesian join" is simply an inner join for which no join conditions have been specified, resulting in all pairs of rows being output.
Thanks to RusselH for pointing out FULL joins, which I'd omitted.
quirksmode has a good description of the 'text-overflow' property, but you may need to apply some additional properties like 'white-space: nowrap'
Whilst I'm not 100% how this will behave in a select object, it could be worth trying this first:
>>> A = ['a1', 'a2', 'a3']
>>> B = ['b1', 'b2', 'b3']
>>> for x in A:
for i in B:
print ">" + x + "\n" + i
Outputs:
>a1
b1
>a1
b2
>a1
b3
>a2
b1
>a2
b2
>a2
b3
>a3
b1
>a3
b2
>a3
b3
Notice that you are using /n
which is not correct!

The Problem might be from the driver name for example instead of DRIVER={MySQL ODBC 5.3 Driver}
try DRIVER={MySQL ODBC 5.3 Unicode Driver}
you can see the name of the driver from administration tool
If you want to print the last 10 lines, use
tail(dataset, 10)
for the first 10, you could also do
head(dataset, 10)
for /f "delims=" %%i in ("%0") do set "curpath=%%~dpi"
echo "%curpath%"
or
echo "%cd%"
The double quotes are needed if the path contains any &
characters.
Old question, but I found this useful. Turns out, there's also a specialized class for a Dictionary using a string for both the key and the value:
private static readonly StringDictionary SegmentSyntaxErrorCodes = new StringDictionary
{
{ "1", "Unrecognized segment ID" },
{ "2", "Unexpected segment" }
};
Edit: Per Chris's comment below, using Dictionary<string, string>
over StringDictionary
is generally preferred but will depend on your situation. If you're dealing with an older code base, you might be limited to the StringDictionary
. Also, note that the following line:
myDict["foo"]
will return null if myDict
is a StringDictionary
, but an exception will be thrown in case of Dictionary<string, string>
. See the SO post he mentioned for more information, which is the source of this edit.
In the .h:
typedef enum {
PlayerStateOff,
PlayerStatePlaying,
PlayerStatePaused
} PlayerState;
You have several choices. The one that makes the most sense really depends on what you're trying to do.
Choice 1: make toyNumber a public member variable in a class
class MyToy {
public int toyNumber;
}
then pass a reference to a MyToy to your method.
void play(MyToy toy){
System.out.println("Toy number in play " + toy.toyNumber);
toy.toyNumber++;
System.out.println("Toy number in play after increement " + toy.toyNumber);
}
Choice 2: return the value instead of pass by reference
int play(int toyNumber){
System.out.println("Toy number in play " + toyNumber);
toyNumber++;
System.out.println("Toy number in play after increement " + toyNumber);
return toyNumber
}
This choice would require a small change to the callsite in main so that it reads, toyNumber = temp.play(toyNumber);
.
Choice 3: make it a class or static variable
If the two functions are methods on the same class or class instance, you could convert toyNumber into a class member variable.
Choice 4: Create a single element array of type int and pass that
This is considered a hack, but is sometimes employed to return values from inline class invocations.
void play(int [] toyNumber){
System.out.println("Toy number in play " + toyNumber[0]);
toyNumber[0]++;
System.out.println("Toy number in play after increement " + toyNumber[0]);
}
There are a lot of correct/same answers, but for future references:
Same stands for Tomcat 7. Be aware that updating only your used frameworks' versions (as proposed in other similar questions) isn't enough.
You also have to update Tomcat plugin's version. What worked for me, using Java 7, was upgrading to version 2.2 of tomcat7-maven-plugin (= Tomcat 7.0.47).
This is how I managed to do what I was trying to do:
[Test]
public void TransferHandlesDisconnect()
{
// ... set up config here
var methodTester = new Mock<Transfer>(configInfo);
methodTester.CallBase = true;
methodTester
.Setup(m =>
m.GetFile(
It.IsAny<IFileConnection>(),
It.IsAny<string>(),
It.IsAny<string>()
))
.Throws<System.IO.IOException>();
methodTester.Object.TransferFiles("foo1", "foo2");
Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}
If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.
As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:
<?php
$world = _("World");
$str = <<<EOF
<p>Hello</p>
<p>$world</p>
EOF;
echo $str;
?>
a workaround idea that comes to mind is building a class with a magic getter method.
You would declare a class like this:
class Translator
{
public function __get($name) {
return _($name); // Does the gettext lookup
}
}
Initialize an object of the class at some point:
$translate = new Translator();
You can then use the following syntax to do a gettext lookup inside a HEREDOC block:
$str = <<<EOF
<p>Hello</p>
<p>{$translate->World}</p>
EOF;
echo $str;
?>
$translate->World
will automatically be translated to the gettext lookup thanks to the magic getter method.
To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!
, you will have to use the following notation:
$translate->{"Hello World!!!!!!"}
This is all untested but should work.
Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.
It isn't giving any errors?
Try
SET @tmpType = 'premium
'
and
SET @tmpType = 'basic'
Try this code:
Dim lastrow As Long
lastrow = Cells(Rows.Count, 2).End(xlUp).Row
Range("A3:D" & lastrow).Sort key1:=Range("B3:B" & lastrow), _
order1:=xlAscending, Header:=xlNo
So I see here tons of answers that are frankly overcomplicated, and that's an understatement.
The answer is pretty simple: :: it's called a Method References https://docs.oracle.com/javase/tutorial/java/javaOO/methodreferences.html
So I won't copy-paste, on the link, you can find all the information if you scroll down to the table.
Now, let's take a short look at what is a Method References:
A::b somewhat substitutes the following inline lambda expression: (params ...) -> A.b(params ...)
To correlate this with your questions, it's necessary to understand a java lambda expression. Which is not hard.
An inline lambda expression is similar to a defined functional interface (which is an interface that has no more and no less than 1 method). Let's take a short look what I mean:
InterfaceX f = (x) -> x*x;
InterfaceX must be a functional interface. Any functional interface, the only thing what's important about InterfaceX for that compiler is that you define the format:
InterfaceX can be any of this:
interface InterfaceX
{
public Integer callMe(Integer x);
}
or this
interface InterfaceX
{
public Double callMe(Integer x);
}
or more generic:
interface InterfaceX<T,U>
{
public T callMe(U x);
}
Let's take the first presented case and the inline lambda expression that we defined earlier.
Before Java 8, you could've defined it similarly this way:
InterfaceX o = new InterfaceX(){
public int callMe (int x)
{
return x*x;
} };
Functionally, it's the same thing. The difference is more in how the compiler perceives this.
Now that we took a look at inline lambda expression, let's return to Method References (::). Let's say you have a class like this:
class Q {
public static int anyFunction(int x)
{
return x+5;
}
}
Since method anyFunctions has the same types as InterfaceX callMe, we can equivalate those two with a Method Reference.
We can write it like this:
InterfaceX o = Q::anyFunction;
and that is equivalent to this :
InterfaceX o = (x) -> Q.anyFunction(x);
A cool thing and advantage of Method References are that at first, until you assign them to variables, they are typeless. So you can pass them as parameters to any equivalent looking (has same defined types) functional interface. Which is exactly what happens in your case
First add an Enrty
and Category
class:
public class Entry { public string Id { get; set; } public string Title { get; set; } public string Updated { get; set; } public string Summary { get; set; } public string GPoint { get; set; } public string GElev { get; set; } public List<string> Categories { get; set; } } public class Category { public string Label { get; set; } public string Term { get; set; } }
Then use LINQ to XML
XDocument xDoc = XDocument.Load("path"); List<Entry> entries = (from x in xDoc.Descendants("entry") select new Entry() { Id = (string) x.Element("id"), Title = (string)x.Element("title"), Updated = (string)x.Element("updated"), Summary = (string)x.Element("summary"), GPoint = (string)x.Element("georss:point"), GElev = (string)x.Element("georss:elev"), Categories = (from c in x.Elements("category") select new Category { Label = (string)c.Attribute("label"), Term = (string)c.Attribute("term") }).ToList(); }).ToList();
I had a similar problem, what solved it was html_entity_decode
.
My code is:
$content = file_get_contents("http://example.com/fr");
$x = new SimpleXMLElement($content);
foreach($x->channel->item as $entry) {
$subEntry = html_entity_decode($entry->description);
}
In here I am retrieving an xml file (in French), that's why I'm using this $x object variable. And only then I decode it into this variable $subEntry
.
I tried mb_convert_encoding
but this didn't work for me.
A simple SQL example would be like this:
ALTER TABLE `<table_name>` ADD `<column_name>` INT(11) NULL DEFAULT NULL ;
Make sure you use back ticks `` in table name and column name
You have your print() statement in the for()
loop, It should be after so that it only prints once. the way it currently is, every time the max changes it prints a max
.
If you couldn't find http.conf
and followed Nick's way.
Restart Apache using sudo service apache2 restart
.
Building on Matteo Furlans design, when he said "most dynamic array implementations work by starting off with an array of some (small) default size, then whenever you run out of space when adding a new element, double the size of the array". The difference in the "work in progress" below is that it doesn't double in size, it aims at using only what is required. I have also omitted safety checks for simplicity...Also building on brimboriums idea, I have tried to add a delete function to the code...

Look forward to the constructive criticism to follow...
I'm not really sure if I got your question right. Maybe something like
public class CommentsController : Controller
{
[HttpPost]
public ActionResult WriteComment(CommentModel comment)
{
// Do the basic model validation and other stuff
try
{
if (ModelState.IsValid )
{
// Insert the model to database like:
db.Comments.Add(comment);
db.SaveChanges();
// Pass the comment's article id to the read action
return RedirectToAction("Read", "Articles", new {id = comment.ArticleID});
}
}
catch ( Exception e )
{
throw e;
}
// Something went wrong
return View(comment);
}
}
public class ArticlesController : Controller
{
// id is the id of the article
public ActionResult Read(int id)
{
// Get the article from database by id
var model = db.Articles.Find(id);
// Return the view
return View(model);
}
}
Yes. You can get an element by its ID by calling document.getElementById
. It will return an element node if found, and null
otherwise:
var x = document.getElementById("elementid"); // Get the element with id="elementid"
x.style.color = "green"; // Change the color of the element
You have to define the compare first. There are 3 ways to do that:
It's easy to use class/struct because easy to declare just write this line of code above your executing code
struct compare{
public:
bool operator()(Node& a,Node& b) // overloading both operators
{
return a.w < b.w: // if you want increasing order;(i.e increasing for minPQ)
return a.w > b.w // if you want reverse of default order;(i.e decreasing for minPQ)
}
};
Calling code:
priority_queue<Node,vector<Node>,compare> pq;
You can do it using clone()
function of jQuery, Accepted answer is ok but i am providing alternative to it, you can use append()
, but it works only if you can change html slightly as below:
$(document).ready(function(){_x000D_
$('#clone_btn').click(function(){_x000D_
$("#car_parent").append($("#car2").clone());_x000D_
});_x000D_
});
_x000D_
.car-well{_x000D_
border:1px solid #ccc;_x000D_
text-align: center;_x000D_
margin: 5px;_x000D_
padding:3px;_x000D_
font-weight:bold;_x000D_
}

Here's a command I think could be of some help :
apachectl -t -D DUMP_VHOSTS
You'll get a list of all the vhosts, you'll know which one is the default one and you'll make sure that your syntax is correct (same as apachectl configtest suggested by yojimbo87).
You'll also know where each vhost is declared. It can be handy if your config files are a mess. ;)
You can place your tables in a div and add style to your table "float: left"
<div>
<table style="float: left">
<tr>
<td>..</td>
</tr>
</table>
<table style="float: left">
<tr>
<td>..</td>
</tr>
</table>
</div>
or simply use css:
div>table {
float: left
}
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other. -- http://docs.angularjs.org/api/ng.directive:ngApp

Another way is to bundle these things into an artifact using the assembly plugin. Then you can use the dependency plugin to unpack these files where you want. There are also copy goals in the dependency plugin to copy artifacts.
This probably isn't exactly the answer you're looking for, but having struggled with this myself and having issues with suggested answers, I decided to make it uncontrolled instead.
When editable
prop is false
, I use text
prop as is, but when it is true
, I switch to editing mode in which text
has no effect (but at least browser doesn't freak out). During this time onChange
are fired by the control. Finally, when I change editable
back to false
, it fills HTML with whatever was passed in text
:
/** @jsx React.DOM */
'use strict';
var React = require('react'),
escapeTextForBrowser = require('react/lib/escapeTextForBrowser'),
{ PropTypes } = React;
var UncontrolledContentEditable = React.createClass({
propTypes: {
component: PropTypes.func,
onChange: PropTypes.func.isRequired,
text: PropTypes.string,
placeholder: PropTypes.string,
editable: PropTypes.bool
},
getDefaultProps() {
return {
component: React.DOM.div,
editable: false
};
},
getInitialState() {
return {
initialText: this.props.text
};
},
componentWillReceiveProps(nextProps) {
if (nextProps.editable && !this.props.editable) {
this.setState({
initialText: nextProps.text
});
}
},
componentWillUpdate(nextProps) {
if (!nextProps.editable && this.props.editable) {
this.getDOMNode().innerHTML = escapeTextForBrowser(this.state.initialText);
}
},
render() {
var html = escapeTextForBrowser(this.props.editable ?
this.state.initialText :
this.props.text
);
return (
<this.props.component onInput={this.handleChange}
onBlur={this.handleChange}
contentEditable={this.props.editable}
dangerouslySetInnerHTML={{__html: html}} />
);
},
handleChange(e) {
if (!e.target.textContent.trim().length) {
e.target.innerHTML = '';
}
this.props.onChange(e);
}
});
module.exports = UncontrolledContentEditable;
This error message is very confusing. I just fixed the other 'warnings' in my project and I really had only one (simple one):
warning C4101: 'i': unreferenced local variable
After I commented this unused i
, and compiled it, the other error went away.
You cannot use WHILE
like that; see: mysql DECLARE WHILE outside stored procedure how?
You have to put your code in a stored procedure. Example:
CREATE PROCEDURE myproc()
BEGIN
DECLARE i int DEFAULT 237692001;
WHILE i <= 237692004 DO
INSERT INTO mytable (code, active, total) VALUES (i, 1, 1);
SET i = i + 1;
END WHILE;
END
Fiddle: http://sqlfiddle.com/#!2/a4f92/1
Alternatively, generate a list of INSERT
statements using any programming language you like; for a one-time creation, it should be fine. As an example, here's a Bash one-liner:
for i in {2376921001..2376921099}; do echo "INSERT INTO mytable (code, active, total) VALUES ($i, 1, 1);"; done
By the way, you made a typo in your numbers; 2376921001 has 10 digits, 237692200 only 9.
Sorry, but none of the previous solutions helped me. I need to check both sides: SecurityManager and SO permissions. I have learned a lot with Josh code and with iain answer, but I'm afraid I need to use Rakesh code (also thanks to him). Only one bug: I found that he only checks for Allow and not for Deny permissions. So my proposal is:
string folder;
AuthorizationRuleCollection rules;
try {
rules = Directory.GetAccessControl(folder)
.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount));
} catch(Exception ex) { //Posible UnauthorizedAccessException
throw new Exception("No permission", ex);
}
var rulesCast = rules.Cast<FileSystemAccessRule>();
if(rulesCast.Any(rule => rule.AccessControlType == AccessControlType.Deny)
|| !rulesCast.Any(rule => rule.AccessControlType == AccessControlType.Allow))
throw new Exception("No permission");
//Here I have permission, ole!
Stream: In laymen terms stream is data , most generic stream is binary representation of data.
Input Stream : If you are reading data from a file or any other source , stream used is input stream. In a simpler terms input stream acts as a channel to read data.
Output Stream : If you want to read and process data from a source (file etc) you first need to save the data , the mean to store data is output stream .
execute following command from your terminal
sudo pip install --allow-external mysql-connector-python mysql-connector-python
Matlab allows you to return multiple values as well as receive them inline.
When you call it, receive individual variables inline:
[array, listp, freep] = initialize(size)
Better way:
encodeURIComponent escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )
To avoid unexpected requests to the server, you should call encodeURIComponent on any user-entered parameters that will be passed as part of a URI. For example, a user could type "Thyme &time=again" for a variable comment. Not using encodeURIComponent on this variable will give comment=Thyme%20&time=again. Note that the ampersand and the equal sign mark a new key and value pair. So instead of having a POST comment key equal to "Thyme &time=again", you have two POST keys, one equal to "Thyme " and another (time) equal to again.
For application/x-www-form-urlencoded (POST), per http://www.w3.org/TR/html401/interac...m-content-type, spaces are to be replaced by '+', so one may wish to follow a encodeURIComponent replacement with an additional replacement of "%20" with "+".
If one wishes to be more stringent in adhering to RFC 3986 (which reserves !, ', (, ), and *), even though these characters have no formalized URI delimiting uses, the following can be safely used:
function fixedEncodeURIComponent (str) {
return encodeURIComponent(str).replace(/[!'()]/g, escape).replace(/\*/g, "%2A");
}
You can use : org.springframework.util.StringUtils
;
String stringDelimitedByComma = StringUtils.collectionToCommaDelimitedString(myList);
Use JavaScript objects. You can access their properties like keys in a dictionary. This is the foundation of JSON. The syntax is similar to Python dictionaries. See: JSON.org
You actually don't need to use the attach at all. I had the same problem and it was resolved by removing the attach statement.
CSS has different pseudo selector by which you can achieve such effect. In your case you can use
:active : if you want background color only when the button is clicked and don't want to persist.
:focus: if you want background color untill the focus is on the button.
button:active{
background:olive;
}
and
button:focus{
background:olive;
}
P.S.: Please don't give the number in Id
attribute of html elements.
If your database recovery model is full and you didn't have a log backup maintenance plan, you will get this error because the transaction log becomes full due to LOG_BACKUP
.
This will prevent any action on this database (e.g. shrink), and the SQL Server Database Engine will raise a 9002 error.
To overcome this behavior I advise you to check this The transaction log for database ‘SharePoint_Config’ is full due to LOG_BACKUP that shows detailed steps to solve the issue.
It's the value returned by that object's toString()
function.
I understand what you're trying to do, because I answered your question yesterday about determining which div is visible. :)
The whichIsVisible()
function returns an actual jQuery object, because I thought that would be more programmatically useful. If you want to use this function for debugging purposes, you can just do something like this:
function whichIsVisible_v2()
{
if (!$1.is(':hidden')) return '#1';
if (!$2.is(':hidden')) return '#2';
