To make the answer provided by @abourget more complete, the value of scopeValue[field] in the following line of code could be undefined. This would result in an error when setting subfield:
<textarea ng-model="scopeValue[field][subfield]"></textarea>
One way of solving this problem is by adding an attribute ng-focus="nullSafe(field)", so your code would look like the below:
<textarea ng-focus="nullSafe(field)" ng-model="scopeValue[field][subfield]"></textarea>
Then you define nullSafe( field ) in a controller like the below:
$scope.nullSafe = function ( field ) {
if ( !$scope.scopeValue[field] ) {
$scope.scopeValue[field] = {};
}
};
This would guarantee that scopeValue[field] is not undefined before setting any value to scopeValue[field][subfield].
Note: You can't use ng-change="nullSafe(field)" to achieve the same result because ng-change happens after the ng-model has been changed, which would throw an error if scopeValue[field] is undefined.
I didn't understand your problem clearly but I think this is what you're looking for(Based on my understanding)
person = {"name"=>"BillGates", "company_name"=>"Microsoft", "position"=>"Chairman"}
person.delete_if {|key, value| key == "name"} #doing something if the key == "something"
Output: {"company_name"=>"Microsoft", "position"=>"Chairman"}
To be able to disable/enable selects first of all your selects need an ID or class. Then you could do something like this:
Disable:
$('#id').attr('disabled', 'disabled');
Enable:
$('#id').removeAttr('disabled');
open notepad
write
@echo off
javac Main.java
java Main
3.saveAs blahblah.bat
make sure that Main.java resides with your batch file and java path is set in env. variable
4 . double click on batch file, no need to open cmd explicitly tt will open itself on .bat execution
Actually you can capture Query strings in MVC in two ways.....
public ActionResult CrazyMVC(string knownQuerystring)
{
// This is the known query string captured by the Controller Action Method parameter above
string myKnownQuerystring = knownQuerystring;
// This is what I call the mysterious "unknown" query string
// It is not known because the Controller isn't capturing it
string myUnknownQuerystring = Request.QueryString["unknownQuerystring"];
return Content(myKnownQuerystring + " - " + myUnknownQuerystring);
}
This would capture both query strings...for example:
/CrazyMVC?knownQuerystring=123&unknownQuerystring=456
Output: 123 - 456
Don't ask me why they designed it that way. Would make more sense if they threw out the whole Controller action system for individual query strings and just returned a captured dynamic list of all strings/encoded file objects for the URL by url-form-encoding so you can easily access them all in one call. Maybe someone here can demonstrate that if its possible?
Makes no sense to me how Controllers capture query strings, but it does mean you have more flexibility to capture query strings than they teach you out of the box. So pick your poison....both work fine.
To create such an array you could do:
array = ['1', '2', '3']
This is an example with ChartJs - 2.9.4
var maximumPoints = 5;// with this variable you can decide how many points are display on the chart
function addData(chart, label, data) {
chart.data.labels.push(label);
chart.data.datasets.forEach((dataset) => {
var d = data[0];
dataset.data.push(d);
data.shift();
});
var canRemoveData = false;
chart.data.datasets.forEach((dataset) => {
if (dataset.data.length > maximumPoints) {
if (!canRemoveData) {
canRemoveData = true;
chart.data.labels.shift();
}
dataset.data.shift();
}
});
chart.update();
}
window.onload = function () {
var canvas = document.getElementById('elm-chart'),
ctx = canvas.getContext('2d');
var myLineChart = new Chart(ctx, {
type: 'line',
data: {
labels: [],

},
options: {

maintainAspectRatio: false,

yAxes: [{

beginAtZero: true
}
}]
}
}
});
var index = 0;
setInterval(function () {
var data = [];
myLineChart.data.datasets.forEach((dataset) => {
data.push(Math.random() * 100);
});
addData(myLineChart, index, data);
index++;
}, 1000);

You are looking for --build-arg
and the ARG
instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg
to the Dockerfile
and then build with docker build --build-arg arg=2.3 .
.
I also had this problem and was able to solve it by enabling CORS support on the server. In my case it was an Azure server and it was easy: Enable CORS on Azure
So check for your server how it works and enable CORS. I didn't even need a browser plugin or proxy :)
Boolean

Reading a CSV file in very simple and common in Java. You actually don't require to load any extra third party library to do this for you. CSV (comma separated value) file is just a normal plain-text file, store data in column by column, and split it by a separator (e.g comma ",").
In order to read specific columns from the CSV file, there are several ways. Simplest of all is as below:
Code to read CSV without any 3rd party library
BufferedReader br = new BufferedReader(new FileReader(csvFile));
while ((line = br.readLine()) != null) {
// use comma as separator
String[] cols = line.split(cvsSplitBy);
System.out.println("Coulmn 4= " + cols[4] + " , Column 5=" + cols[5]);
}
If you notice, nothing special is performed here. It is just reading a text file, and spitting it by a separator – ",".
Consider an extract from legacy country CSV data at GeoLite Free Downloadable Databases
"1.0.0.0","1.0.0.255","16777216","16777471","AU","Australia"
"1.0.1.0","1.0.3.255","16777472","16778239","CN","China"
"1.0.4.0","1.0.7.255","16778240","16779263","AU","Australia"
"1.0.8.0","1.0.15.255","16779264","16781311","CN","China"
"1.0.16.0","1.0.31.255","16781312","16785407","JP","Japan"
"1.0.32.0","1.0.63.255","16785408","16793599","CN","China"
"1.0.64.0","1.0.127.255","16793600","16809983","JP","Japan"
"1.0.128.0","1.0.255.255","16809984","16842751","TH","Thailand"
Above code will output as below:
Column 4= "AU" , Column 5="Australia"
Column 4= "CN" , Column 5="China"
Column 4= "AU" , Column 5="Australia"
Column 4= "CN" , Column 5="China"
Column 4= "JP" , Column 5="Japan"
Column 4= "CN" , Column 5="China"
Column 4= "JP" , Column 5="Japan"
Column 4= "TH" , Column 5="Thailand"
You can, in fact, put
the columns in a Map
and then get the values simply by using the key
.

I was having the same issue implementing in Angular 9. These are the two steps I did:
Change your YouTube URL from https://youtube.com/your_code
to https://youtube.com/embed/your_code
.
And then pass the URL through DomSanitizer
of Angular.
import { Component, OnInit } from "@angular/core";
import { DomSanitizer } from '@angular/platform-browser';
@Component({
selector: "app-help",
templateUrl: "./help.component.html",
styleUrls: ["./help.component.scss"],
})
export class HelpComponent implements OnInit {
youtubeVideoLink: any = 'https://youtube.com/embed/your_code'
constructor(public sanitizer: DomSanitizer) {
this.sanitizer = sanitizer;
}
ngOnInit(): void {}
getLink(){
return this.sanitizer.bypassSecurityTrustResourceUrl(this.youtubeVideoLink);
}
}
<iframe width="420" height="315" [src]="getLink()" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
The existing answers can be simplified:
from numpy import exp, abs, angle
def polar2z(r,theta):
return r * exp( 1j * theta )
def z2polar(z):
return ( abs(z), angle(z) )
Or even:
polar2z = lambda r,?: r * exp( 1j * ? )
z2polar = lambda z: ( abs(z), angle(z) )
Note these also work on arrays!
rS, thetaS = z2polar( [z1,z2,z3] )
zS = polar2z( rS, thetaS )
I had this issue with a custom list and while it's not possible to use the auto-generated ID column to create a calculated column, it is possible to use a workflow to do the heavy lifting.
I created a new workflow variable of type Number and set it to be the value of the ID column in the current item. Then it's simply a matter of calculating the custom column value and setting it - in my case I just needed the numbering to begin at 100,000.
I also like to use NOT EXISTS. When it comes to performance if index correctly it should perform the same as a LEFT JOIN or better. Plus its easier to read.
SELECT Column1
FROM TableA a
WHERE NOT EXISTS ( SELECT Column1
FROM Tableb b
WHERE a.Column1 = b.Column1
)
That worked for me,
Right Click on project -> "Run as Maven Test". This will automatically download the missing plugins and than Right Click on project ->"Update Maven project" it removes the error.
void CallFunction ()
{ // <----- At this point the compiler knows
// nothing about the members of B.
B b;
b.bFunction();
}
This happens for the same reason that functions in C cannot call each other without at least one of them being declared as a function prototype.
To fix this issue we need to make sure both classes are declared before they are used. We separate the declaration from the definition. This MSDN article explains in more detail about the declarations and definitions.
class A
{
public:
void CallFunction ();
};
class B: public A
{
public:
virtual void bFunction()
{ ... }
};
void A::CallFunction ()
{
B b;
b.bFunction();
}
Good cocoa function:
-(BOOL) NSStringIsValidEmail:(NSString *)checkString
{
BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:checkString];
}
Discussion on Lax vs. Strict - http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
And because categories are just better, you could also add an interface:
@interface NSString (emailValidation)
- (BOOL)isValidEmail;
@end
Implement
@implementation NSString (emailValidation)
-(BOOL)isValidEmail
{
BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:self];
}
@end
And then utilize:
if([@"[email protected]" isValidEmail]) { /* True */ }
if([@"InvalidEmail@notreallyemailbecausenosuffix" isValidEmail]) { /* False */ }
I'm just going to provide this answer as an alternative @IHeartAndroid's recursive algorithm for discovering all child View
s in a view hierarchy. Note that at the time of this writing, the recursive solution is flawed in that it will contains duplicates in its result.
For those who have trouble wrapping their head around recursion, here's a non-recursive alternative. You get bonus points for realizing this is also a breadth-first search alternative to the depth-first approach of the recursive solution.
private List<View> getAllChildrenBFS(View v) {
List<View> visited = new ArrayList<View>();
List<View> unvisited = new ArrayList<View>();
unvisited.add(v);
while (!unvisited.isEmpty()) {
View child = unvisited.remove(0);
visited.add(child);
if (!(child instanceof ViewGroup)) continue;
ViewGroup group = (ViewGroup) child;
final int childCount = group.getChildCount();
for (int i=0; i<childCount; i++) unvisited.add(group.getChildAt(i));
}
return visited;
}
A couple of quick tests (nothing formal) suggest this alternative is also faster, although that has most likely to do with the number of new ArrayList
instances the other answer creates. Also, results may vary based on how vertical/horizontal the view hierarchy is.

I met the same problem. I found the solution in the solution from kb.vmware.com.
It works for me by adding
usb.quirks.device0 = "0xvid:0xpid skip-refresh"
Detail as below:
vmx | USB: Found device [name:Apple\ IR\ Receiver vid:05ac pid:8240 path:13/7/2 speed:full family:hid]
The line has the name of the USB device and its vid and pid information. Make a note of the vid and pid values.
usb.quirks.device0 = "0xvid:0xpid skip-reset"
For example, for the Apple device found in step 2, this line is:
usb.quirks.device0 = "0x05ac:0x8240 skip-reset"
usb.quirks.device0 = "0xvid:0xpid skip-refresh"
usb.quirks.device0 = "0xvid:0xpid skip-setconfig"
usb.quirks.device0 = "0xvid:0xpid skip-reset, skip-refresh, skip-setconfig"
Notes:
Refer this to see in detail.
You can use onclick
to run some JavaScript or jQuery code before submitting the form like this:
<script type="text/javascript">
beforeSubmit = function(){
if (1 == 1){
//your before submit logic
}
$("#formid").submit();
}
</script>
<input type="button" value="Click" onclick="beforeSubmit();" />
What worked for me immediately was:
I located bin folder (picture below shows).
moved all dll in other folder for safety.
then rebuild ed the project.
after solved the issue, deleted old dll files.
Please just go to your terminal then type:
$rm __pycache__
and it will be removed.
string myString = sourceString.Remove(sourceString.IndexOf(removeString),removeString.Length);
EDIT: @OregonGhost is right. I myself would break the script up with conditionals to check for such an occurence, but I was operating under the assumption that the strings were given to belong to each other by some requirement. It is possible that business-required exception handling rules are expected to catch this possibility. I myself would use a couple of extra lines to perform conditional checks and also to make it a little more readable for junior developers who may not take the time to read it thoroughly enough.
You can use ResolveUrl
<link type="text/css" rel="stylesheet" href="<%=Page.ResolveUrl("~/Content/table-sorter.css")%>" />
Incase of lookup_food_array is array.

Faced the same Issue. While running ngserve you should be in the apps directory. To confirm(on GIT BASH : you will have (master) after the directory path at gitbash prompt, if you are at app directory.)
With accordance with the answer by daveraja, here is a bash script which will solve the purpose.
Consider a situation if you are using C-shell and you want to execute a command without leaving the C-shell context/window as follows,
Command to be executed: Search exact word 'Testing' in current directory recursively only in *.h, *.c files
grep -nrs --color -w --include="*.{h,c}" Testing ./
Solution 1: Enter into bash from C-shell and execute the command
bash
grep -nrs --color -w --include="*.{h,c}" Testing ./
exit
Solution 2: Write the intended command into a text file and execute it using bash
echo 'grep -nrs --color -w --include="*.{h,c}" Testing ./' > tmp_file.txt
bash tmp_file.txt
Solution 3: Run command on the same line using bash
bash -c 'grep -nrs --color -w --include="*.{h,c}" Testing ./'
Solution 4: Create a sciprt (one-time) and use it for all future commands
alias ebash './execute_command_on_bash.sh'
ebash grep -nrs --color -w --include="*.{h,c}" Testing ./
The script is as follows,
#!/bin/bash

You can pass variable on the command line via --extra-vars "name=value"
. Sudo password variable is ansible_sudo_pass
. So your command would look like:
ansible-playbook playbook.yml -i inventory.ini --user=username \
--extra-vars "ansible_sudo_pass=yourPassword"
Update 2017: Ansible 2.2.1.0 now uses var ansible_become_pass
. Either seems to work.
jQuery Feeds is a nice option, it has a built-in templating system and uses the Google Feed API, so it has cross-domain support.
I did it by writing a little C# app that just wakes up to launch periodic tasks -- don't know if it is doable from a batch file without downloading extensions to support a sleep command. (For my purposes the Windows scheduler didn't work because the apps launched had no graphics context available.)
You can only use Core Graphics (Quartz, 2D only) transforms directly applied to a UIView's transform property. To get the effects in coverflow, you'll have to use CATransform3D, which are applied in 3-D space, and so can give you the perspective view you want. You can only apply CATransform3Ds to layers, not views, so you're going to have to switch to layers for this.
Check out the "CovertFlow" sample that comes with Xcode. It's mac-only (ie not for iPhone), but a lot of the concepts transfer well.
The default value of end
is \n
meaning that after the print
statement it will print a new line. So simply stated end
is what you want to be printed after the print
statement has been executed
Eg: - print ("hello",end=" +")
will print hello +
CSS3: http://webdesign.about.com/od/styleproperties/p/blspbgsize.htm
.style1 {
...
background-size: 100%;
}
You can specify just width or height with:
background-size: 100% 50%;
Which will stretch it 100% of the width and 50% of the height.

array_slice()
can be used to extract parts of the array, and the union array operator (+
) can recombine the parts.
$res = array_slice($array, 0, 3, true) +
array("my_key" => "my_value") +
array_slice($array, 3, count($array)-3, true);
This example:
$array = array(
'zero' => '0',
'one' => '1',
'two' => '2',
'three' => '3',
);
$res = array_slice($array, 0, 3, true) +
array("my_key" => "my_value") +
array_slice($array, 3, count($array) - 1, true) ;
print_r($res);
gives:
Array ( [zero] => 0 [one] => 1 [two] => 2 [my_key] => my_value [three] => 3 )
[Update April 2016] This answer is now outdated, custom naked domain mapping is supported, see Lawrence Mok's answer.
I have figured it out!
First off: it is impossible to link something like mydomain.com
with your appspot app. This is considered a naked domain, which is not supported by Google App Engine (anymore). Strictly speaking, the answer to my question has to be "impossible". Read on...
All you can do is add subdomains pointing to your app, e.g myappid.mydomain.com
. The key to get your top level domain linked to your app is to realize that www
is a subdomain like any other!
myappid.mydomain.com
is treated exactly the same as www.mydomain.com
!
Here are the steps:
www
and click Addwww
for your domain and point to ghs.googlehosted.com
Now you have www.mydomain.com
linked to your app.
I wished this would have been more obvious in the documentation...Good luck!
XAMPP for linux and mac comes with ProFTPD. Make sure to start the service from XAMPP control panel -> manage servers.
Further complete instructions can be found at localhost XAMPP dashboard -> How-to guides -> Configure FTP Access. I have pasted them below :
Open a new Linux terminal and ensure you are logged in as root.
Create a new group named ftp. This group will contain those user accounts allowed to upload files via FTP.
groupadd ftp
usermod -a -G ftp susan
cd /opt/lampp chown root.ftp htdocs chmod 775 htdocs
You can now transfer files to the XAMPP server using the steps below:
If you’re connecting to the server from the same system, use "127.0.0.1" as the host address. If you’re connecting from a different system, use the network hostname or IP address of the XAMPP server.
Use "21" as the port.
Enter your Linux username and password as your FTP credentials.
Your FTP client should now connect to the server and enter the /opt/lampp/htdocs/ directory, which is the default Web server document root.
Once the file is successfully transferred, you should be able to see it in action.
There's already a question about this, you could perhaps read it
There's no Clone() method as it exists in Java for example, but you could include a copy constructor in your clases, that's another good approach.
class A
{
private int attr
public int Attr
{
get { return attr; }
set { attr = value }
}
public A()
{
}
public A(A p)
{
this.attr = p.Attr;
}
}
This would be an example, copying the member 'Attr' when building the new object.
Here is a very easy way of doing that
$(function () {
$(".glyphicon").unbind('click');
$(".glyphicon").click(function (e) {
$(this).toggleClass("glyphicon glyphicon-chevron-up glyphicon glyphicon-chevron-down");
});
Hope this helps :D
While dict.copy()
and dict(dict1)
generates a copy, they are only shallow copies. If you want a deep copy, copy.deepcopy(dict1)
is required. An example:
>>> source = {'a': 1, 'b': {'m': 4, 'n': 5, 'o': 6}, 'c': 3}
>>> copy1 = x.copy()
>>> copy2 = dict(x)
>>> import copy
>>> copy3 = copy.deepcopy(x)
>>> source['a'] = 10 # a change to first-level properties won't affect copies
>>> source
{'a': 10, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> copy1
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> copy2
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> copy3
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> source['b']['m'] = 40 # a change to deep properties WILL affect shallow copies 'b.m' property
>>> source
{'a': 10, 'c': 3, 'b': {'m': 40, 'o': 6, 'n': 5}}
>>> copy1
{'a': 1, 'c': 3, 'b': {'m': 40, 'o': 6, 'n': 5}}
>>> copy2
{'a': 1, 'c': 3, 'b': {'m': 40, 'o': 6, 'n': 5}}
>>> copy3 # Deep copy's 'b.m' property is unaffected
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
Regarding shallow vs deep copies, from the Python copy
module docs:
The difference between shallow and deep copying is only relevant for compound objects (objects that contain other objects, like lists or class instances):
- A shallow copy constructs a new compound object and then (to the extent possible) inserts references into it to the objects found in the original.
- A deep copy constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original.
If you need to perform this List.contains(Object with field value equal to x)
repeatedly, a simple and efficient workaround would be:
List<field obj type> fieldOfInterestValues = new ArrayList<field obj type>;
for(Object obj : List) {
fieldOfInterestValues.add(obj.getFieldOfInterest());
}
Then the List.contains(Object with field value equal to x)
would be have the same result as fieldOfInterestValues.contains(x);
import numpy as np
mean_data = np.array([
[6.0, 315.0, 4.8123788544375692e-06],
[6.5, 0.0, 2.259217450023793e-06],
[6.5, 45.0, 9.2823565008402673e-06],
[6.5, 90.0, 8.309270169336028e-06],
[6.5, 135.0, 6.4709418114245381e-05],
[6.5, 180.0, 1.7227922423558414e-05],
[6.5, 225.0, 1.2308522579848724e-05],
[6.5, 270.0, 2.6905672894824344e-05],
[6.5, 315.0, 2.2727114437176048e-05]])
R = mean_data[:,0]
print R
print R.shape
EDIT
The reason why you had an invalid index
error is the lack of a comma between mean_data
and the values you wanted to add.
Also, np.append returns a copy of the array, and does not change the original array. From the documentation :
Returns : append : ndarray
A copy of arr with values appended to axis. Note that append does not occur in-place: a new array is allocated and filled. If axis is None, out is a flattened array.
So you have to assign the np.append
result to an array (could be mean_data
itself, I think), and, since you don't want a flattened array, you must also specify the axis on which you want to append.
With that in mind, I think you could try something like
mean_data = np.append(mean_data, [[ur, ua, np.mean(data[samepoints,-1])]], axis=0)
Do have a look at the doubled [[
and ]]
: I think they are necessary since both arrays must have the same shape.
Batch files are not an executable. They need an application to run them (i.e. cmd).
On UNIX, the script file has shebang (#!) at the start of a file to specify the program that executes it. Double-clicking in Windows is performed by Windows Explorer. CreateProcess
does not know anything about that.
Runtime.
getRuntime().
exec("cmd /c start \"\" build.bat");
Note: With the start \"\"
command, a separate command window will be opened with a blank title and any output from the batch file will be displayed there. It should also work with just `cmd /c build.bat", in which case the output can be read from the sub-process in Java if desired.
Maybe try this? It seems the problem is solved after remove all the handlers in my case.
for handler in logging.root.handlers[:]:
logging.root.removeHandler(handler)
logging.basicConfig(filename='output.log', level=logging.INFO)

For example for all users (Builtin\Users), this method works fine - enjoy.
public static bool HasFolderWritePermission(string destDir)
{
if(string.IsNullOrEmpty(destDir) || !Directory.Exists(destDir)) return false;
try
{
DirectorySecurity security = Directory.GetAccessControl(destDir);
SecurityIdentifier users = new SecurityIdentifier(WellKnownSidType.BuiltinUsersSid, null);
foreach(AuthorizationRule rule in security.GetAccessRules(true, true, typeof(SecurityIdentifier)))
{
if(rule.IdentityReference == users)
{
FileSystemAccessRule rights = ((FileSystemAccessRule)rule);
if(rights.AccessControlType == AccessControlType.Allow)
{
if(rights.FileSystemRights == (rights.FileSystemRights | FileSystemRights.Modify)) return true;
}
}
}
return false;
}
catch
{
return false;
}
}
Another possibility is to use regular expressions which is what Perl is famous for:
if ($mystring =~ /s1\.domain\.com/) {
print qq("$mystring" contains "s1.domain.com"\n);
}
The backslashes are needed because a .
can match any character. You can get around this by using the \Q
and \E
operators.
my $substring = "s1.domain.com";
if ($mystring =~ /\Q$substring\E/) {
print qq("$mystring" contains "$substring"\n);
}
Or, you can do as eugene y stated and use the index function.
Just a word of warning: Index returns a -1
when it can't find a match instead of an undef
or 0
.
Thus, this is an error:
my $substring = "s1.domain.com";
if (not index($mystring, $substr)) {
print qq("$mystring" doesn't contains "$substring"\n";
}
This will be wrong if s1.domain.com
is at the beginning of your string. I've personally been burned on this more than once.
This question contains some useful links on headless builds, but they are mostly geared towards building plugins. I'm not sure how much of it can be applied to pure Java projects.
Only a single origin can be specified for the Access-Control-Allow-Origin header. But you can set the origin in your response according to the request. Also don't forget to set the Vary header. In PHP I would do the following:
/**
* Enable CORS for the passed origins.
* Adds the Access-Control-Allow-Origin header to the response with the origin that matched the one in the request.
* @param array $origins
* @return string|null returns the matched origin or null
*/
function allowOrigins($origins)
{
$val = $_SERVER['HTTP_ORIGIN'] ?? null;
if (in_array($val, $origins, true)) {
header('Access-Control-Allow-Origin: '.$val);
header('Vary: Origin');
return $val;
}
return null;
}
if (allowOrigins(['http://localhost', 'https://localhost'])) {
echo your response here, e.g. token
}
to set the height of table, you need to first set css property "display: block" then you can add "width/height" properties. I find this Mozilla Article a very good resource to learn how to style tables : Link
Built a modal popup example using syarul's jsFiddle link. Here is the updated fiddle.
Created an angular directive called modal and used in html. Explanation:-
HTML
<div ng-controller="MainCtrl" class="container">
<button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
<button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
<button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
<button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
<modal visible="showModal">
Any additional data / buttons
</modal>
</div>
On button click toggleModal() function is called with the button message as parameter. This function toggles the visibility of popup. Any tags that you put inside will show up in the popup as content since ng-transclude is placed on modal-body in the directive template.
JS
var mymodal = angular.module('mymodal', []);
mymodal.controller('MainCtrl', function ($scope) {
$scope.showModal = false;
$scope.buttonClicked = "";
$scope.toggleModal = function(btnClicked){
$scope.buttonClicked = btnClicked;
$scope.showModal = !$scope.showModal;
};
});
mymodal.directive('modal', function () {
return {
template: '<div class="modal fade">' +
'<div class="modal-dialog">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>' +
'<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' +
'</div>' +
'<div class="modal-body" ng-transclude></div>' +
'</div>' +
'</div>' +
'</div>',
restrict: 'E',
transclude: true,
replace:true,
scope:true,
link: function postLink(scope, element, attrs) {
scope.title = attrs.title;
scope.$watch(attrs.visible, function(value){
if(value == true)
$(element).modal('show');
else
$(element).modal('hide');
});
$(element).on('shown.bs.modal', function(){
scope.$apply(function(){
scope.$parent[attrs.visible] = true;
});
});
$(element).on('hidden.bs.modal', function(){
scope.$apply(function(){
scope.$parent[attrs.visible] = false;
});
});
}
};
});

UPDATE 2 restrict : 'E' : directive to be used as an HTML tag (element). Example in our case is

Other values are 'A' for attribute
<div modal>
'C' for class (not preferable in our case because modal is already a class in bootstrap.css)
<div class="modal">
As an addition to the Gerold Broser's answer, here an example of mocking a static method with arguments:
class Buddy {
static String addHello(String name) {
return "Hello " + name;
}
}
...
@Test
void testMockStaticMethods() {
assertThat(Buddy.addHello("John")).isEqualTo("Hello John");
try (MockedStatic<Buddy> theMock = Mockito.mockStatic(Buddy.class)) {
theMock.when(() -> Buddy.addHello("John")).thenReturn("Guten Tag John");
assertThat(Buddy.addHello("John")).isEqualTo("Guten Tag John");
}
assertThat(Buddy.addHello("John")).isEqualTo("Hello John");
}
The accepted answer works if you set the JSON as a key/value pair in the form-data
panel (See the image hereunder)
Nevertheless, I am wondering if it is a very clean way to design an API. If it is mandatory for you to upload both image and JSON in a single call maybe it is ok but if you could separate the routes (one for image uploading, the other for JSON body with a proper content-type header), it seems better.
You can use it in the same datafram (df) using the previously provided code
df[!grepl("REVERSE", df$Name),]
or you might assign a different name to the datafram using this code
df1<-df[!grepl("REVERSE", df$Name),]
try with following code. make elements with class name page-scroll and keep id name to href
of corresponding links
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: ($($anchor.attr('href')).offset().top - 50)
}, 1250, 'easeInOutExpo');
event.preventDefault();
});
hr {

then go to developer tab, macros, select the macro, click options, then add a shortcut letter or button.

tl;dr Use image specified at https://docs.travis-ci.com/user/common-build-problems/#troubleshooting-locally-in-a-docker-image in combination with https://github.com/travis-ci/travis-build#use-as-addon-for-travis-cli.
#troubleshooting-locally-in-a-docker-image
section was replaced by #running-builds-in-debug-mode
which also describes how to SSH to the job running in the debug mode.
EDIT 2019-07-26
#troubleshooting-locally-in-a-docker-image
section is no longer part of the docs; here's why
Though, it's still in git history: https://github.com/travis-ci/docs-travis-ci-com/pull/2193.
Look for (quite old, couldn't find newer) image versions at: https://travis-ci.org/travis-ci/docs-travis-ci-com/builds/230889063#L661.
I wanted to inspect why one of the tests in my build failed with an error I din't get locally.
Worked.
What actually worked was using the image specified at Troubleshooting Locally in a Docker Image docs page. In my case it was travisci/ci-garnet:packer-1512502276-986baf0
.
I was able to add travise compile

Definitely not Trusty (Ubuntu 14.04) and not small either.
I think the problem is here:
[contains(text()='Some text')]
To break this down,
[]
are a conditional that operates on each individual node in
that node set -- each span node in your case. It matches if any of the individual nodes it operates
on match the conditions inside the brackets. text()
is a selector
that matches all of the text nodes that are children of the context
node -- it returns a node set. contains
is a function that operates
on a string. If it is passed a node set, the node set is converted
into a string by returning the string-value of the node in the
node-set that is first in document order.You should try to change this to
[text()[contains(.,'Some text')]]
The outer []
are a conditional that operates on each individual node
in that node set text()
is a selector that matches all of the text
nodes that are children of the context node -- it returns a node
set.
The inner []
are a conditional that operates on each node in that
node set.
contains
is a function that operates on a string. Here it is passed
an individual text node (.
).
How can I get the item name "Mon, Tue, etc" when I already have the item value "0, 1, etc."
On some older C code (quite some time ago), I found code analogous to:
std::string weekEnumToStr(int n)
{
std::string s("unknown");
switch (n)
{
case 0: { s = "Mon"; } break;
case 1: { s = "Tue"; } break;
case 2: { s = "Wed"; } break;
case 3: { s = "Thu"; } break;
case 4: { s = "Fri"; } break;
case 5: { s = "Sat"; } break;
case 6: { s = "Sun"; } break;
}
return s;
}
Con: This establishes a "pathological dependency" between the enumeration values and the function... meaning if you change the enum you must change the function to match. I suppose this is true even for a std::map.
I vaguely remember we found a utility to generate the function code from the enum code. The enum table length had grown to several hundred ... and at some point it is maybe a sound choice to write code to write code.
Note -
in an embedded system enhancement effort, my team replaced many tables (100+?) of null-terminated-strings used to map enum int values to their text strings.
The problem with the tables was that a value out of range was often not noticed because many of these tables were gathered into one region of code / memory, such that a value out-of-range reached past the named table end(s) and returned a null-terminated-string from some subsequent table.
Using the function-with-switch statement also allowed us to add an assert in the default clause of the switch. The asserts found several more coding errors during test, and our asserts were tied into a static-ram-system-log our field techs could search.
I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.
To answer the question in the header: To install make in ubuntu you have to install build-essentials
sudo apt-get install build-essential
yes you need to use a having clause after the Group by clause , as the where is just to filter the data on simple parameters , but group by followed by a Having statement is the idea to group the data and filter it on basis of some aggregate function......
If you are using an array (and purely an array), the lookup of "contains" is O(N)
, because worst case, you must iterate the entire array. Now if the array is sorted you can use a binary search, which reduces the search time to log(N)
with the overhead of the sort.
If this is something that is invoked repeatedly, place it in a function:
private boolean inArray(int[] array, int value)
{
for (int i = 0; i < array.length; i++)
{
if (array[i] == value)
{
return true;
}
}
return false;
}
More oftenly most of the applications will have data,display and processing part and we just put all those in the letters M
,V
and C
.
Model(M
)-->Has the attributes that holds state of application and it dont know any thing about V
and C
.
View(V
)-->Has displaying format for the application and and only knows about how-to-digest model on it and does not bother about C
.
Controller(C
)---->Has processing part of application and acts as wiring between M and V and it depends on both M
,V
unlike M
and V
.
Altogether there is separation of concern between each. In future any change or enhancements can be added very easily.
For me changing the Emulated Performance setting to "Store a snapshot for faster startup" and unchecking "Use Host GPU" fixed the problem.
Object properties can be checked for existence by property_exists
Example from a unit test:
function testPropertiesExist()
{
$sl =& $this->system_log;
$props = array('log_id',
'type',
'message',
'username',
'ip_address',
'date_added');
foreach($props as $prop) {
$this->assertTrue(property_exists($sl, $prop),
"Property <{$prop}> exists");
}
}
Building on the solution by MoonScript, you could try this instead:

The benefit is that since it's a lower level solution, it will enable CORS (to the extent possible) on IE 8/9 with other frameworks, not just with jQuery. I've had success using it with AngularJS, as well as jQuery 1.x and 2.x.
More simply you can utilize DropBox for this. The steps basically remain the same. You can do the following-:
1) upload your .ipa to dropBox, Share the link for this .ipa
2) Paste the shared link for .ipa in your manifest.plist file , Upload manifest file in DropBox again share the link for this .plist file
3)paste the link for this Plist in your index.html file with a suitable tag.
Share this index.html file with anybody who can tap on the URL and download. or you can directly hit the URL instead.

You need to set M2 and M2_HOME. I was facing same problem and issue was I had put one extra space in PATH variable after semicolon. Just removed space from path and it worked. (Windows 7 machine)
If you're going to have a method that just runs the switch and then returns some value, then sure this way works. But if you want a switch with other stuff in a method then you can't use return or the rest of the code inside the method will not execute. Notice in the tutorial how it has a print after the code? Yours would not be able to do this.
+(NSString*)date2str:(NSDate*)myNSDateInstance onlyDate:(BOOL)onlyDate{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
if (onlyDate) {
[formatter setDateFormat:@"yyyy-MM-dd"];
}else{
[formatter setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
}
//Optionally for time zone conversions
// [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"..."]];
NSString *stringFromDate = [formatter stringFromDate:myNSDateInstance];
return stringFromDate;
}
+(NSDate*)str2date:(NSString*)dateStr{
if ([dateStr isKindOfClass:[NSDate class]]) {
return (NSDate*)dateStr;
}
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];
NSDate *date = [dateFormat dateFromString:dateStr];
return date;
}
This is the most simple way you can do it since you can't clear $_POST data by refreshing the page but by leaving the page and coming back to it again.
This will be on the page you would want to clear $_POST
data.
<a class="btn" href="clear_reload.php"> Clear</a> // button to 'clear' data
Now create clear_reload.php
.
clear_reload.php:
<?php
header("Location: {$_SERVER['HTTP_REFERER']}");
?>
The "clear" button will direct you to this clear_reload.php
page, which will redirect you back to the same page you were at.
Your quotes only need to surround the value part of the attribute-equals selector, [attr='val']
, like this:
$('a#check_var').click(function() {
alert($("input:radio[name='r']:checked").val()+ ' '+
$("input:radio[name='s']:checked").val());
});?
pg_dump -d <databasename> -h <hostname> -p <port> -n <schemaname> -f <location of the dump file>
Please notice that you have sufficient privilege to access that schema.
If you want take backup as specific user add user name in that command preceded by -U
After beating my head on this for at least an hour, I offer this answer to try to expand on the comments some others have made. To ignore a folder/directory, do the following: if you don't have a .gitignore file in the root of your project (that name exactly ".gitignore"), create a dummy text file in the folder you want to exclude. Inside of Source Tree, right click on it and select Ignore. You'll get a popup that looks like this.
Select "Everything underneath" and select the folder you want to ignore from the drop-down list. This will create a .gitignore file in your root directory and put the folder specification in it.
If you do have a .gitignore folder already in your root folder, you could follow the same approach above, or you can just edit the .gitignore file and add the folder you want to exclude. It's just a text file. Note that it uses forward slashes in path names rather than backslashes, as we Windows users are accustomed to. I tried creating a .gitignore text file by hand in Windows Explorer, but it didn't let me create a file without a name (i.e. with only the extension).
Note that adding the .gitignore and the file specification will have no effect on files that are already being tracked. If you're already tracking these, you'll have to stop tracking them. (Right-click on the folder or file and select Stop Tracking.) You'll then see them change from having a green/clean or amber/changed icon to a red/removed icon. On your next commit the files will be removed from the repository and thereafter appear with a blue/ignored icon. Another contributor asked why Ignore was disabled for particular files and I believe it was because he was trying to ignore a file that was already being tracked. You can only ignore a file that has a blue question mark icon.
A safer way to approach breaking a foreach
or while
loop in PHP is to nest an incrementing counter variable and if
conditional inside of the original loop. This gives you tighter control than break;
which can cause havoc elsewhere on a complicated page.
Example:
// Setup a counter
$ImageCounter = 0;
// Increment through repeater fields
while ( condition ):
$ImageCounter++;
// Only print the first while instance
if ($ImageCounter == 1) {
echo 'It worked just once';
}
// Close while statement
endwhile;
In HTML, elements containing nothing but normal whitespace characters are considered empty. A paragraph that contains just a normal space character will have zero height. A non-breaking space is a special kind of whitespace character that isn't considered to be insignificant, so it can be used as content for a non-empty paragraph.
Even if you consider CSS margins on paragraphs, since an "empty" paragraph has zero height, its vertical margins will collapse. This causes it to have no height and no margins, making it appear as if it were never there at all.
The simple answer is to turn off async
. But that's the wrong thing to do. The correct answer is to re-think how you write the rest of your code.
Instead of writing this:
function functABC(){
$.ajax({
url: 'myPage.php',
data: {id: id},
success: function(data) {
return data;
}
});
}
function foo () {
var response = functABC();
some_result = bar(response);
// and other stuff and
return some_result;
}
You should write it like this:
function functABC(callback){
$.ajax({
url: 'myPage.php',
data: {id: id},
success: callback
});
}
function foo (callback) {
functABC(function(data){
var response = data;
some_result = bar(response);
// and other stuff and
callback(some_result);
})
}
That is, instead of returning result, pass in code of what needs to be done as callbacks. As I've shown, callbacks can be nested to as many levels as you have function calls.
A quick explanation of why I say it's wrong to turn off async:
Turning off async will freeze the browser while waiting for the ajax call. The user cannot click on anything, cannot scroll and in the worst case, if the user is low on memory, sometimes when the user drags the window off the screen and drags it in again he will see empty spaces because the browser is frozen and cannot redraw. For single threaded browsers like IE7 it's even worse: all websites freeze! Users who experience this may think you site is buggy. If you really don't want to do it asynchronously then just do your processing in the back end and refresh the whole page. It would at least feel not buggy.
Obviously, talking about speed Ruby loses. Even though benchmark tests suggest that Ruby is not so much slower than PHP. But in return, you are getting easy-to-maintain DRY code, the best out of all frameworks in various languages.
For a small project, you wont feel any slowness (I mean until like <50K users) given that no complex calculations are used in the code, just the mainstream stuff.
For a bigger project, paying for resources pays off and is cheaper than developer wages. In addition, writing code on RoR turns out to be much faster than any other.
In 2014 this magnitude of speed difference you're talking about is for most websites insignificant.
This expression 12-4-2005
is a calculated int and the value is -1997
. You should do like this instead '2005-04-12'
with the '
before and after.
PyDev
PyDev has a pretty good interactive debugger. It has watch expressions, hover-to-evaluate, thread and stack listings and (almost) all the usual amenities you expect from a modern visual debugger. You can even attach to a running process and do remote debugging.
Like other visual debuggers, though, I find it useful mostly for simple problems, or for very complicated problems after I've tried everything else. I still do most of the heavy lifting with logging.
For information
if anyone use
$('#formId').submit();
Do not something like this
<button name = "submit">
It took many hours to find me that submit() won't work like this.
Just complementing the answer.
Merging the last tag on a branch:
git checkout my-branch
git merge $(git describe --tags $(git rev-list --tags --max-count=1))
Inspired by https://gist.github.com/rponte/fdc0724dd984088606b0
Provided that your int column is nullable, you may write:
UPDATE dbo.TableName
SET TableName.IntColumn = NULL
WHERE <condition>
try {
var data = {foo: "bar"};
res.json(JSON.stringify(data));
}
catch (e) {
res.status(500).json(JSON.stringify(e));
}
Go to Window → Preferences → Java → Installed JREs. Select the JRE you're using, click Edit, and there will be a line for Default VM Arguments which will apply to every execution. For instance, I use this on OS X to hide the icon from the dock, increase max memory and turn on assertions:
-Xmx512m -ea -Djava.awt.headless=true
Here's a solution using a negative lookahead (not supported in all regex engines):
^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$
Test that it works as expected:
import re
tests = [
('a', True),
('_', False),
('zz', True),
('a0', True),
('A_', False),
('a0_b', True),
('a__b', False),
('a_1_c', True),
]
regex = '^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$'
for test in tests:
is_match = re.match(regex, test[0]) is not None
if is_match != test[1]:
print "fail: " + test[0]
You use something like
from flask import send_file
@app.route('/get_image')
def get_image():
if request.args.get('type') == '1':
filename = 'ok.gif'
else:
filename = 'error.gif'
return send_file(filename, mimetype='image/gif')
to send back ok.gif
or error.gif
, depending on the type query parameter. See the documentation for the send_file
function and the request
object for more information.
Not sure if this will help somebody else out or not but this was the key part to fix my problem in user "Tom Hawtin - tacklin"'s answer above:
synchronized (lock) {
makeWakeupNeeded();
lock.notifyAll();
}
Just the fact that the "lock" is passed as an argument in synchronized() and it is also used in "lock".notifyAll();
Once I made it in those 2 places I got it working
what about array_search? seems it quite faster than foreach according to https://gist.github.com/Ocramius/1290076 ..
if( array_search("Irix", $a) === true)
{
echo "Got Irix";
}
For me, I was writing to a file that is opened in Excel.
I did not realize that the first nested element is actually an array. The correct way access to the post code key is as follows:
r = requests.get('http://api.zippopotam.us/us/ma/belmont')
j = r.json()
print j['state']
print j['places'][1]['post code']
for(int i=0;i<ar.length();i++) {
char ch = ar.charAt(i);
System.out.println((char)(ch+16));;
}
Consider having multiple matlab sessions. Keep the main session window (the pretty one with all the colours, file manager, command history, workspace, editor etc.) for running stuff that you know will terminate.
Stuff that you are experimenting with, say you are messing with ode suite and you get lots of warnings: matrix singular, because you altered some parameter and didn't predict what would happen, run in a separate session:
dos('matlab -automation -r &')
You can kill that without having to restart the whole of Matlab.
To check if there is a GPU available:
torch.cuda.is_available()
If the above function returns False
,
CUDA_VISIBLE_DEVICES
. When the value of CUDA_VISIBLE_DEVICES
is -1, then all your devices are being hidden. You can check that value in code with this line: os.environ['CUDA_VISIBLE_DEVICES']
If the above function returns True
that does not necessarily mean that you are using the GPU. In Pytorch you can allocate tensors to devices when you create them. By default, tensors get allocated to the cpu
. To check where your tensor is allocated do:
# assuming that 'a' is a tensor created somewhere else
a.device # returns the device where the tensor is allocated
Note that you cannot operate on tensors allocated in different devices. To see how to allocate a tensor to the GPU, see here: https://pytorch.org/docs/stable/notes/cuda.html
Theoretically, you can compare edit distances.
On my system, I don't have the rename
command. Here is a simple one liner. It finds all the HTML files recursively and adds prefix_
in front of their names:
for f in $(find . -name '*.html'); do mv "$f" "$(dirname "$f")/prefix_$(basename "$f")"; done
insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
ts.tax_status_id,
( select r.recipient_id
from recipient r
where r.recipient_code = ?
)
from tax_status ts
where ts.tax_status_code = ?
I should add: You should not be putting your dll's into \system32\ anyway! Modify your code, modify your installer... find a home for your bits that is NOT anywhere under c:\windows\
For example, your installer puts your dlls into:
\program files\<your app dir>\
or
\program files\common files\<your app name>\
(Note: The way you actually do this is to use the environment var: %ProgramFiles% or %ProgramFiles(x86)% to find where Program Files is.... you do not assume it is c:\program files\ ....)
and then sets a registry tag :
HKLM\software\<your app name>
-- dllLocation
The code that uses your dlls reads the registry, then dynamically links to the dlls in that location.
The above is the smart way to go.
You do not ever install your dlls, or third party dlls into \system32\ or \syswow64. If you have to statically load, you put your dlls in your exe dir (where they will be found). If you cannot predict the exe dir (e.g. some other exe is going to call your dll), you may have to put your dll dir into the search path (avoid this if at all poss!)
system32 and syswow64 are for Windows provided files... not for anyone elses files. The only reason folks got into the bad habit of putting stuff there is because it is always in the search path, and many apps/modules use static linking. (So, if you really get down to it, the real sin is static linking -- this is a sin in native code and managed code -- always always always dynamically link!)
JavaScript is a dynamic language. You could just add it to the object itself.
var marker = new google.maps.Marker(markerOptions);
marker.metadata = {type: "point", id: 1};
Also, because all v3 objects extend MVCObject()
. You can use:
marker.setValues({type: "point", id: 1});
// or
marker.set("type", "point");
marker.set("id", 1);
var val = marker.get("id");
Kalle posted a link to a page that has this video on it, but it's done on XP. If you use Windows 7:
alt + n
alt + e
;
(that's a semicolon)C:\Python27
windows key + r
to bring up the run dialog. Type in python
and press enter.I had the same error and it was underlining the Assembly Vesrion and Assembly File Version so reading Luqi answer I just added them as comments and the error was solved
// AssemblyVersion is the CLR version. Change this only when making breaking changes
//[assembly: AssemblyVersion("3.1.*")]
// AssemblyFileVersion should ideally be changed with each build, and should help identify the origin of a build
//[assembly: AssemblyFileVersion("3.1.0.0")]
I think it's best if you use methods with generic arguments, like the following :
public static void SerializeToXml<T>(T obj, string fileName)
{
using (var fileStream = new FileStream(fileName, FileMode.Create))
{
var ser = new XmlSerializer(typeof(T));
ser.Serialize(fileStream, obj);
}
}
public static T DeserializeFromXml<T>(string xml)
{
T result;
var ser = new XmlSerializer(typeof(T));
using (var tr = new StringReader(xml))
{
result = (T)ser.Deserialize(tr);
}
return result;
}
I suggest visit Add digest auth in jmx-console and read oficial documentation for Configure admin consoles, you can add more security to your JBoss AS console and at these link explains where are the role and user/pass files that you need to change this information for your server and how you can change them. Also I recommend you quit all consoles that you don't use because they can affect to application server's performance. Also there are others links about securing jmx-console that could help you, search in jboss as community site for them (I can't put them here for my actual reputation,sorry). Never you should has the password in plain text over conf/props/ files.
Sorry for my bad English and I hope my answer be useful for you.
Try this:
select songName from t
where personName in ('Ryan', 'Holly')
group by songName
having count(distinct personName) = 2
The number in the having should match the amount of people. If you also need the Status to be Complete
use this where
clause instead of the previous one:
where personName in ('Ryan', 'Holly') and status = 'Complete'
you need only set default value to parameters(you do not need the Route attribute):
public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }
Well in my case I wanted to unit-test the equality operator. I needed call the code under the equality operators without explicitly setting the generic type. Advises for EqualityComparer
were not helpful as EqualityComparer
called Equals
method but not the equality operator.
Here is how I've got this working with generic types by building a LINQ
. It calls the right code for ==
and !=
operators:
/// <summary>
/// Gets the result of "a == b"
/// </summary>
public bool GetEqualityOperatorResult<T>(T a, T b)
{
// declare the parameters
var paramA = Expression.Parameter(typeof(T), nameof(a));
var paramB = Expression.Parameter(typeof(T), nameof(b));
// get equality expression for the parameters
var body = Expression.Equal(paramA, paramB);
// compile it
var invokeEqualityOperator = Expression.Lambda<Func<T, T, bool>>(body, paramA, paramB).Compile();
// call it
return invokeEqualityOperator(a, b);
}
/// <summary>
/// Gets the result of "a =! b"
/// </summary>
public bool GetInequalityOperatorResult<T>(T a, T b)
{
// declare the parameters
var paramA = Expression.Parameter(typeof(T), nameof(a));
var paramB = Expression.Parameter(typeof(T), nameof(b));
// get equality expression for the parameters
var body = Expression.NotEqual(paramA, paramB);
// compile it
var invokeInequalityOperator = Expression.Lambda<Func<T, T, bool>>(body, paramA, paramB).Compile();
// call it
return invokeInequalityOperator(a, b);
}
I was getting the same error, You can fix through one of this method:
If you don't have any nested module
a. Import the CommonModule in your App module
b. Import your Component where you are adding the *ngFor in the App Module, define in declarations
// file App.modules.ts
@NgModule({
declarations: [
LoginComponent // declarations of your component
],
imports: [
BrowserModule
DemoMaterialModule,
FormsModule,
HttpClientModule,
ReactiveFormsModule,
AppRoutingModule,
BrowserAnimationsModule,
ServiceWorkerModule.register('ngsw-worker.js', { enabled: environment.production })
],
providers: [
ApiService,
CookieService,
{
provide: HTTP_INTERCEPTORS,
useClass: ApiInterceptor,
multi: true
}
],
bootstrap: [AppComponent]
})
c. If you are using the separate module file for routing then Import the CommonModule in your Routing module else Import the CommonModule in your App module
// file app.routing.modules.ts
import { LoginComponent } from './login/login.component';
import { CommonModule } from "@angular/common";
const routes: Routes = [
{ path: '', component: LoginComponent },
{ path: 'login', component: LoginComponent }
];
@NgModule({
imports: [RouterModule,RouterModule.forRoot(routes), CommonModule],
exports: [RouterModule]
})
In my case, the 2nd method solved my issue.
Hope this will help you
A Context
is:
Even shorter version of the solution from Dominic Zukiewicz:
ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;
But this means that you will trust all certificates. For a service that isn't just run locally, something a bit smarter will be needed. In the first instance you could use this code to just test whether it solves your problem.
Looking at the jQuery code, this is what happens:
hide: function( speed, easing, callback ) {
if ( speed || speed === 0 ) {
return this.animate( genFx("hide", 3), speed, easing, callback);
} else {
for ( var i = 0, j = this.length; i < j; i++ ) {
var display = jQuery.css( this[i], "display" );
if ( display !== "none" ) {
jQuery.data( this[i], "olddisplay", display );
}
}
// Set the display of the elements in a second loop
// to avoid the constant reflow
for ( i = 0; i < j; i++ ) {
this[i].style.display = "none";
}
return this;
}
},
line-height
is how you vertically align text. It is pretty standard and I don't consider it a "hack". Just add line-height: 100px
to your ul.catBlock li
and it will be fine.
In this case you may have to add it to ul.catBlock li a
instead since all of the text inside the li
is also inside of an a
. I have seen some weird things happen when you do this, so try both and see which one works.
I will tell , how i solved almost similar problem. I developed a application using VS 2013 and tried to create wizard for it failed to do. Later i installed premium VS and tried and failed.
at last i used "ClickOnce" and it worked fine.
So i believe here also , "CLICKONCE" would help you.
I work on PHP and have used Swagger 2.0 to document the APIs. The Swagger Document is created on the fly (at least that is what I use in PHP). The document is generated in the JSON format.

This can be imported into Postman as follow.
You can also use 'Import From Link'. Here paste the URL which generates the JSON format of the APIs from the Swagger or any other API Document tool.
This is my Document (JSON) generation file. It's in PHP. I have no idea of JAVA along with Swagger.

I tried to edit the answer provided by marc_s however it wasn't accepted for some reason. It formats the sql for easier reading, includes the schema and also names the Default name so that this can easily be pasted into other code.
SELECT SchemaName = s.Name,
TableName = t.Name,
ColumnName = c.Name,
DefaultName = dc.Name,
DefaultDefinition = dc.Definition
FROM sys.schemas s
JOIN sys.tables t on t.schema_id = s.schema_id
JOIN sys.default_constraints dc on dc.parent_object_id = t.object_id
JOIN sys.columns c on c.object_id = dc.parent_object_id
and c.column_id = dc.parent_column_id
ORDER BY s.Name, t.Name, c.name
This also works.

I recommend using the python bindings to OpenImageIO, it's the standard for dealing with various image formats in the vfx world. I've ovten found it more reliable in reading various compression types compared to PIL.
import OpenImageIO as oiio
input = oiio.ImageInput.open ("/path/to/image.tif")
The class you apply on the div can be used to as a reference point to style elements with that div, for example.
<div class="area1">
<table>
<tr>
<td class="item">Text Text Text</td>
<td class="item">Text Text Text</td>
</tr>
</table>
</div>
.area1 { border:1px solid black; }
.area1 td { color:red; } /* This will effect any TD within .area1 */
To be super semantic you should move the class onto the table.
<table class="area1">
<tr>
<td>Text Text Text</td>
<td>Text Text Text</td>
</tr>
</table>
In Firefox, https://bug743252.bugzilla.mozilla.org/attachment.cgi?id=714383 (view page source :: tag HTML).

In others browsers, I don't know, but you can view http://www.mintprintables.com/print-tips/header-footer-windows/
Just re-add the src argument on a separate line after the img oject is defined. This will trick IE into triggering the lad-event. It is ugly, but it is the simplest workaround I've found so far.

})
.load(function() {

.appendTo('#someelement');
$('#whatever').attr('src', url); // trigger .load on IE

My code was broken because I was using a deprecated technique. It used to be this:
video.src = window.URL.createObjectURL(localMediaStream);
video.play();
Then I replaced that with this:
video.srcObject = localMediaStream;
video.play();
That worked beautifully.
EDIT: Recently localMediaStream
has been deprecated and replaced with MediaStream
. The latest code looks like this:
video.srcObject = new MediaStream();
References:
You've an number of options, depending on how you want to play it:
isNaN(val)
Returns true if val is not a number, false if it is. In your case, this is probably what you need.
isFinite(val)
Returns true if val, when cast to a String, is a number and it is not equal to +/- Infinity
/^\d+$/.test(val)
Returns true if val, when cast to a String, has only digits (probably not what you need).
Just remove the "px" in the style.height assignation, like:
<button type="button" onClick = "document.getElementById('chartdiv').style.height = 200px"> </button>
Should be
<button type="button" onClick = "document.getElementById('chartdiv').style.height = 200">Click Me!</button>

A simple view like this was giving me the ORA-01861 error when executed from Entity Framework:
create view myview as
select * from x where x.initialDate >= '01FEB2021'
Just did something like this to fix it:
create view myview as
select * from x where x.initialDate >= TO_DATE('2021-02-01', 'YYYY-MM-DD')
I think the problem is EF date configuration is not the same as Oracle's.
This does the trick, without the need to add an inline style
<div class="row-fluid">
<div class="span6">
<p>text left</p>
</div>
<div class="span6">
<div class="pull-right">
<p>text right</p>
</div>
</div>
</div>
The answer is in nesting another <div>
with the "pull-right" class. Combining the two classes won't work.
You can do something like this:
a = [1,2,3,4,5]
b = [i**2 for i in a]

You can get the colors for any theme (including the builtin ones) by switching to the theme then choosing Developer > Generate Color Theme From Current Settings
from the command palette.
Details
Switch to the builtin theme you wish to modify by selecting Preferences: Color Theme
from the command palette then choosing the theme.
Get the colors for that theme by choosing Developer > Generate Color Theme From Current Settings
from the command palette. Save the file with the suffix -color-theme.jsonc
.
The color-theme
part will enable color picker widgets when editing the file and jsonc
sets the filetype to JSON with comments

From the command palette choose Preferences: Open Settings (JSON)
to open your settings.json
file. Then add your desired changes to either the workbench.colorCustomizations
or tokenColorCustomizations
section.
[]
) and the value is an associative array of settings.settings.json
at workbench.colorTheme
.For example, the following customizes the theme listed as Dark+ (default dark)
from the Color Theme list. It sets the editor background to near black and the syntax highlighting for comments to a dim gray.
// settings.json
"workbench.colorCustomizations": {
"[Default Dark+]": {
"editor.background": "#19191f"
}
},
"editor.tokenColorCustomizations": {
"[Default Dark+]": {
"comments": "#5F6167"
}
},
In late, but got here via Google, so for the sake of posterity, I'll add an alternative solution.
Another approach is to use TOP twice, with alternating orders. I don't know if it is "pure SQL", because it uses a variable in the TOP, but it works in SQL Server 2008. Here's an example I use against a table of dictionary words, if I want a random word.
SELECT TOP 1
word
FROM (
SELECT TOP(@idx)
word
FROM
dbo.DictionaryAbridged WITH(NOLOCK)
ORDER BY
word DESC
) AS D
ORDER BY
word ASC
Of course, @idx is some randomly-generated integer that ranges from 1 to COUNT(*) on the target table, inclusively. If your column is indexed, you'll benefit from it too. Another advantage is that you can use it in a function, since NEWID() is disallowed.
Lastly, the above query runs in about 1/10 of the exec time of a NEWID()-type of query on the same table. YYMV.

If you are sure you want to remove all commit history, simply delete the .git
directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:
git init
git remote add origin [email protected]:user/repo
now commit your current version of code
git add *
git commit -am 'message'
and finally force the update to GitHub:
git push -f origin master
However, I suggest backing up the history (the .git
folder in the repository) before taking these steps!
I just want to share my new finding: https://laragon.org/docs/index.html

You can make a new file under [.git\refs\remotes\origin] with name "HEAD" and put content "ref: refs/remotes/origin/master" to it. This should solve your problem.
It seems that clone from an empty repos will lead to this. Maybe the empty repos do not have HEAD because no commit object exist.
You can use the
git log --remotes --branches --oneline --decorate
to see the difference between each repository, while the "problem" one do not have "origin/HEAD"
Edit: Give a way using command line
You can also use git command line to do this, they have the same result
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master
To know the format string used by Excel without having to guess it: create an excel file, write a date in cell A1 and format it as you want. Then run the following lines:
FileInputStream fileIn = new FileInputStream("test.xlsx");
Workbook workbook = WorkbookFactory.create(fileIn);
CellStyle cellStyle = workbook.getSheetAt(0).getRow(0).getCell(0).getCellStyle();
String styleString = cellStyle.getDataFormatString();
System.out.println(styleString);
Then copy-paste the resulting string, remove the backslashes (for example d/m/yy\ h\.mm;@
becomes d/m/yy h.mm;@
) and use it in the http://poi.apache.org/spreadsheet/quick-guide.html#CreateDateCells code:
CellStyle cellStyle = wb.createCellStyle();
CreationHelper createHelper = wb.getCreationHelper();
cellStyle.setDataFormat(createHelper.createDataFormat().getFormat("d/m/yy h.mm;@"));
cell = row.createCell(1);
cell.setCellValue(new Date());
cell.setCellStyle(cellStyle);
Although above answers are correct but to make it simple for newbies, all you need to do is set margin, left and right. following code will do it provided that width is set and position is absolute:
margin: 0 auto;
left: 0;
right: 0;
Demo:
.centeredBox {_x000D_
margin: 0 auto;_x000D_
left: 0;_x000D_
right: 0;_x000D_
_x000D_
_x000D_
/** Position should be absolute */_x000D_
position: absolute;_x000D_
/** And box must have a width, any width */_x000D_
width: 40%;_x000D_
background: #faebd7;_x000D_

context.getImageData(x, y, 1, 1).data;
returns an rgba array. e.g. [50, 50, 50, 255]
Here's a version of @lwburk's rgbToHex function that takes the rgba array as an argument.
function rgbToHex(rgb){
return '#' + ((rgb[0] << 16) | (rgb[1] << 8) | rgb[2]).toString(16);

It looks like XMLHttpRequest
has been replaced by the Fetch API. Google published a good introduction that includes this example doing what you want:
fetch('./api/some.json')
.then(
function(response) {
if (response.status !== 200) {
console.log('Looks like there was a problem. Status Code: ' +
response.status);
return;
}
// Examine the text in the response
response.json().then(function(data) {
console.log(data);
});
}
)
.catch(function(err) {
console.log('Fetch Error :-S', err);
});
However, you probably want to call response.text()
instead of response.json()
.
The success option of ajax should not be altered because DataTables uses it internally to execute the table draw when the data load is complete. The recommendation is used "dataSrc" to alter the received data.
Another approach is by using FormBody.Builder()
.
Here's an example of callback:
Callback loginCallback = new Callback() {
@Override
public void onFailure(Call call, IOException e) {
try {
Log.i(TAG, "login failed: " + call.execute().code());
} catch (IOException e1) {
e1.printStackTrace();
}
}
@Override
public void onResponse(Call call, Response response) throws IOException {
// String loginResponseString = response.body().string();
try {
JSONObject responseObj = new JSONObject(response.body().string());
Log.i(TAG, "responseObj: " + responseObj);
} catch (JSONException e) {
e.printStackTrace();
}
// Log.i(TAG, "loginResponseString: " + loginResponseString);
}
};
Then, we create our own body:
RequestBody formBody = new FormBody.Builder()
.add("username", userName)
.add("password", password)
.add("customCredential", "")
.add("isPersistent", "true")
.add("setCookie", "true")
.build();
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(this)
.build();
Request request = new Request.Builder()
.url(loginUrl)
.post(formBody)
.build();
Finally, we call the server:
client.newCall(request).enqueue(loginCallback);

Instead you need to find unicode representation of this characters which are U+000D and U+000A so we can do something like

var string = el.getAttribute('text').replace(/, /, '\u000D\u000A');_x000D_
el.setAttribute('text', string);

}
public static DateTime FirstDateOfWeekOfMonth(int year, int month,

I recently used py2exe to create an executable for post-review for sending reviews to ReviewBoard.
This was the setup.py I used
from distutils.core import setup
import py2exe
setup(console=['post-review'])
It created a directory containing the exe file and the libraries needed. I don't think it is possible to use py2exe to get just a single .exe file. If you need that you will need to first use py2exe and then use some form of installer to make the final executable.
One thing to take care of is that any egg files you use in your application need to be unzipped, otherwise py2exe can't include them. This is covered in the py2exe docs.
Thanks for the above script. One little modification to add in the file ending correctly. Try this ...

I would guess that it is a way to make apps which don't use it at all perform slightly better. Here's my thinking on this.
x86 OSes (and I imagine others) need to store FPU state on context switch. However, most OSes only bother to save/restore this state after the app attempts to use the FPU for the first time.
In addition to this, there is probably some basic code in the math library which will set the FPU to a sane base state when the library is loaded.
So, if you don't link in any math code at all, none of this will happen, therefore the OS doesn't have to save/restore any FPU state at all, making context switches slightly more efficient.
Just a guess though.
EDIT: in response to some of the comments, the same base premise still applies to non-FPU cases (the premise being that it was to make apps which didn't make use libm perform slightly better).
For example, if there is a soft-FPU which was likley in the early days of C. Then having libm separate could prevent a lot of large (and slow if it was used) code from unnecessarily being linked in.
In addition, if there is only static linking available, then a similar argument applies that it would keep executable sizes and compile times down.

Use find. Seriously, it is the best way because then you can really see what files it's operating on:
find . -name "*.sql" -exec grep -H "slow" {} \;
Note, the -H is mac-specific, it shows the filename in the results.
This is a never ending story that reflect the limits (an myth) of "interoperability and portability over all".
What the program should return to indicate "success" should be defined by who is receiving the value (the Operating system, or the process that invoked the program) not by a language specification.
But programmers likes to write code in "portable way" and hence they invent their own model for the concept of "operating system" defining symbolic values to return.
Now, in a many-to-many scenario (where many languages serve to write programs to many system) the correspondence between the language convention for "success" and the operating system one (that no one can grant to be always the same) should be handled by the specific implementation of a library for a specific target platform.
But - unfortunatly - these concept where not that clear at the time the C language was deployed (mainly to write the UNIX kernel), and Gigagrams of books where written by saying "return 0 means success", since that was true on the OS at that time having a C compiler.
From then on, no clear standardization was ever made on how such a correspondence should be handled. C and C++ has their own definition of "return values" but no-one grant a proper OS translation (or better: no compiler documentation say anything about it). 0 means success if true for UNIX - LINUX and -for independent reasons- for Windows as well, and this cover 90% of the existing "consumer computers", that - in the most of the cases - disregard the return value (so we can discuss for decades, bu no-one will ever notice!)
Inside this scenario, before taking a decision, ask these questions: - Am I interested to communicate something to my caller about my existing? (If I just always return 0 ... there is no clue behind the all thing) - Is my caller having conventions about this communication ? (Note that a single value is not a convention: that doesn't allow any information representation)
If both of this answer are no, probably the good solution is don't write the main return statement at all. (And let the compiler to decide, in respect to the target is working to).
If no convention are in place 0=success meet the most of the situations (and using symbols may be problematic, if they introduce a convention).
If conventions are in place, ensure to use symbolic constants that are coherent with them (and ensure convention coherence, not value coherence, between platforms).
Following is worked for me
File dir = new File("E:\\test");
ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/C", "Start","test.bat");
pb.directory(dir);
Process p = pb.start();
If you are using .NET 3.5 or newer you can use LINQ extension methods to achieve a "contains" check with the Any
extension method:
if(CartProducts.Any(prod => prod.ID == p.ID))
This will check for the existence of a product within CartProducts
which has an ID matching the ID of p
. You can put any boolean expression after the =>
to perform the check on.
This also has the benefit of working for LINQ-to-SQL queries as well as in-memory queries, where Contains
doesn't.
If the data to be encoded contains "exotic" characters, I think you have to encode in "UTF-8"
encoded = base64.b64encode (bytes('data to be encoded', "utf-8"))
Go to menu , search for Regional Settings. Switch to Keyboard layouts tab. Click Options button. Search for Key(s) to change layout. There isn't a default one so you have to tick the combination you like. Enjoy.
I always find images helpful when learning a new concept, so this is a supplemental answer.
The %p
means a percentage of the parent, that is, a percentage of the narrowest dimension of whatever view we set our drawable on. The images above were generated by changing the gradientRadius
in this code
my_gradient_drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:type="radial"
android:gradientRadius="10%p"
android:startColor="#f6ee19"
android:endColor="#115ede" />
</shape>
Which can be set on a view's background
attribute like this
<View
android:layout_width="200dp"
android:layout_height="100dp"
android:background="@drawable/my_gradient_drawable"/>
You can change the center of the radius with
android:centerX="0.2"
android:centerY="0.7"
where the decimals are fractions of the width and height for x
and y
respectively.
Here are some notes from the documentation explaining things a little more.
android:gradientRadius
Radius of the gradient, used only with radial gradient. May be an explicit dimension or a fractional value relative to the shape's minimum dimension.
May be a floating point value, such as "1.2".
May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).
May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.
If you'd like to persisist cookies and session data, you'd best do it like this:
import requests
proxies = {
'http': 'http://user:[email protected]:3128',
'https': 'https://user:[email protected]:3128',
}
# Create the session and set the proxies.
s = requests.Session()
s.proxies = proxies
# Make the HTTP request through the session.
r = s.get('http://www.showmemyip.com/')
Important! Vertical center is relative to the height of the parent
If the parent of the element you're trying to center has no defined height, none of the vertical centering solutions will work!
Now, onto vertical centering...
Bootstrap 5 (Updated 2020)
Bootstrap 5 is still flexbox based so vertical centering works the same way as Bootstrap 4. For example align-items-center and justify-content-center can used on the flexbox parent (row
or d-flex
). https://codeply.com/p/0VM5MJ7Had
Bootstrap 4
You can use the new flexbox & size utilities to make the container
full-height and display: flex
. These options don't require extra CSS (except that the height of the container (ie:html,body) must be 100%).
Option 1 align-self-center
on flexbox child
<div class="container d-flex h-100">
<div class="row justify-content-center align-self-center">
I'm vertically centered
</div>
</div>
https://codeply.com/go/fFqaDe5Oey
Option 2 align-items-center
on flexbox parent (.row
is display:flex; flex-direction:row
)
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">
<div class="jumbotron">
I'm vertically centered
</div>
</div>
</div>
</div>
https://codeply.com/go/BumdFnmLuk
Option 3 justify-content-center
on flexbox parent (.card
is display:flex;flex-direction:column
)
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">

More on Bootstrap 4 Vertical Centering
Now that Bootstrap 4 offers flexbox and other utilities, there are many approaches to vertical alignment. http://www.codeply.com/go/WG15ZWC4lf
1 - Vertical Center Using Auto Margins:
Another way to vertically center is to use my-auto
. This will center the element within it's container. For example, h-100
makes the row full height, and my-auto
will vertically center the col-sm-12
column.
<div class="row h-100">
<div class="col-sm-12 my-auto">
<div class="card card-block w-25">Card</div>
</div>
</div>
Vertical Center Using Auto Margins Demo
my-auto
represents margins on the vertical y-axis and is equivalent to:
margin-top: auto;
margin-bottom: auto;
2 - Vertical Center with Flexbox:
Since Bootstrap 4 .row
is now display:flex
you can simply use align-self-center
on any column to vertically center it...
<div class="row">
<div class="col-6 align-self-center">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">

3 - Vertical Center Using Display Utils:
Bootstrap 4 has display utils that can be used for display:table
, display:table-cell
, display:inline
, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.
<div class="row h-50">
<div class="col-sm-12 h-100 d-table">
<div class="card card-block d-table-cell align-middle">
I am centered vertically
</div>
</div>

Important! Did I mention height?
Remember vertical centering is relative to the height of the parent element. If you want to center on the entire page, in most cases, this should be your CSS...
body,html {
height: 100%;
}
Or use min-height: 100vh
(min-vh-100
in Bootstrap 4.1+) on the parent/container. If you want to center a child element inside the parent. The parent must have a defined height.

You need to make your anchor display: block
or display: inline-block;
and then it will accept the width and height values.
For those who are absolutely sure their relative path is correct, my problem was that my files did not have the .rb
extension! (Even though I used RubyMine
to create the files and selected that they were Ruby
files on creation.)
Double check the file extensions on your file!
The exception clearly identifies some .NET 2.0.50727 component was included in .NET 4.0. In App.config file use this:

It solved my problem
A typical way would be to use stringstream
:
#include <iomanip>
#include <sstream>
double pi = 3.14159265359;
std::stringstream stream;
stream << std::fixed << std::setprecision(2) << pi;
std::string s = stream.str();
See fixed
Use fixed floating-point notation
Sets the
floatfield
format flag for the str stream tofixed
.When
floatfield
is set tofixed
, floating-point values are written using fixed-point notation: the value is represented with exactly as many digits in the decimal part as specified by the precision field (precision
) and with no exponent part.
and setprecision.
For conversions of technical purpose, like storing data in XML or JSON file, C++17 defines to_chars family of functions.
Assuming a compliant compiler (which we lack at the time of writing), something like this can be considered:
#include <array>
#include <charconv>
double pi = 3.14159265359;
std::array<char, 128> buffer;
auto [ptr, ec] = std::to_chars(buffer.data(), buffer.data() + buffer.size(), pi,
std::chars_format::fixed, 2);
if (ec == std::errc{}) {
std::string s(buffer.data(), ptr);
// ....
}
else {
// error handling
}
Basically, you want to loop through each direct descendent of the old-parent node, and move it to the new parent. Any children of a direct descendent will get moved with it.
var newParent = document.getElementById('new-parent');
var oldParent = document.getElementById('old-parent');
while (oldParent.childNodes.length > 0) {
newParent.appendChild(oldParent.childNodes[0]);
}
Replace:
myBinding.Source = ViewModel.SomeString;
with:
myBinding.Source = ViewModel;
Example:
Binding myBinding = new Binding();
myBinding.Source = ViewModel;
myBinding.Path = new PropertyPath("SomeString");
myBinding.Mode = BindingMode.TwoWay;
myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(txtText, TextBox.TextProperty, myBinding);
Your source should be just ViewModel
, the .SomeString
part is evaluated from the Path
(the Path
can be set by the constructor or by the Path
property).
To complete the Best Answer:
var round = function ( number, precision )
{
precision = precision || 0;
return parseFloat( parseFloat( number ).toFixed( precision ) );
}
The input parameter number may "not" always be a number, in this case .toFixed does not exist.

To understand closures you have to get down to the program and literally execute as if you are the run time. Let's look at this simple piece of code:
JavaScript runs the code in two phases:
When JavaScript goes through the compilation phase it extract out the declarations of variables and functions. This is called hoisting. Functions encountered in this phase are saved as text blobs in memory also known as lambda. After compilation JavaScript enters the execution phase where it assigns all the values and runs the function. To run the function it prepares the execution context by assigning memory from the heap and repeating the compilation and execution phase for the function. This memory area is called scope of the function. There is a global scope when execution starts. Scopes are the key in understanding closures.
In this example, in first go, variable a
is defined and then f
is defined in the compilation phase. All undeclared variables are saved in the global scope. In the execution phase f
is called with an argument. f
's scope is assigned and the compilation and execution phase is repeated for it.
Arguments are also saved in this local scope for f
. Whenever a local execution context or scope is created it contain a reference pointer to its parent scope. All variable access follows this lexical scope chain to find its value. If a variable is not found in the local scope it follows the chain and find it in its parent scope. This is also why a local variable overrides variables in the parent scope. The parent scope is called the "Closure" for local a scope or function.
Here when g
's scope is being set up it got a lexical pointer to its parents scope of f
. The scope of f
is the closure for g
. In JavaScript, if there is some reference to functions, objects or scopes if you can reach them somehow, it will not get garbage collected. So when myG is running, it has a pointer to scope of f
which is its closure. This area of memory will not get garbage collected even f
has returned. This is a closure as far as the runtime is concerned.
[[scope]]
reference.var data = "My Data!";
setTimeout(function() {
console.log(data); // Prints "My Data!"
}, 3000);
function makeAdder(n) {
var inc = n;
var sum = 0;
return function add() {
sum = sum + inc;
return sum;
};
}
var adder3 = makeAdder(3);
A very interesting talk on closures and more is Arindam Paul - JavaScript VM internals, EventLoop, Async and ScopeChains.
Datasets implement IDisposable thorough MarshalByValueComponent, which implements IDisposable. Since datasets are managed there is no real benefit to calling dispose.
Simple javascript document navigation to "#" will do it.
window.onload = function()
{
document.location.href = "#";
}
This will force the navigation bar to remove itself on load.

Add "Pojo Mapping" and "Jackson Provider" to the jersey client config:
ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
clientConfig.getClasses().add(JacksonJsonProvider.class);
This solve to me!
ClientResponse response = null;
response = webResource

.accept(MediaType.APPLICATION_JSON)
.get(ClientResponse.class);
if (response.getStatus() == Response.Status.OK.getStatusCode()) {
MyClass myclass = response.getEntity(MyClass.class);
System.out.println(myclass);

You can easily do this by css. HTML :
<form id="aform" name="aform" method="POST">
<input name="chkBox_1" type="checkbox" checked value="1" readonly />
<br/>
<input name="chkBox_2" type="checkbox" value="1" readonly />
<br/>
<input id="submitBttn" type="button" value="Submit">
</form>
CSS :
input[type="checkbox"][readonly] {
pointer-events: none;
}
Here is an actual *nix equivalent, i.e. it gives *nix-style output.
Get-Command <your command> | Select-Object -ExpandProperty Definition
Just replace with whatever you're looking for.
PS C:\> Get-Command notepad.exe | Select-Object -ExpandProperty Definition
C:\Windows\system32\notepad.exe
When you add it to your profile, you will want to use a function rather than an alias because you can't use aliases with pipes:
function which($name)
{
Get-Command $name | Select-Object -ExpandProperty Definition
}
Now, when you reload your profile you can do this:
PS C:\> which notepad
C:\Windows\system32\notepad.exe
had the same issue. I had imported a newer version of json library (deleted the old one - but not removed it from the build path). Resolved it by removing the reference to the old one from the build path

return (int) (d + 0.5);
} else {
return (int) (d - 0.5);
