From the output of java -X
:
-Xloggc:<file> log GC status to a file with time stamps
Documented here:
-Xloggc:filename
Sets the file to which verbose GC events information should be redirected for logging. The information written to this file is similar to the output of
-verbose:gc
with the time elapsed since the first GC event preceding each logged event. The-Xloggc
option overrides-verbose:gc
if both are given with the samejava
command.Example:
-Xloggc:garbage-collection.log
So the output looks something like this:
0.590: [GC 896K->278K(5056K), 0.0096650 secs] 0.906: [GC 1174K->774K(5056K), 0.0106856 secs] 1.320: [GC 1670K->1009K(5056K), 0.0101132 secs] 1.459: [GC 1902K->1055K(5056K), 0.0030196 secs] 1.600: [GC 1951K->1161K(5056K), 0.0032375 secs] 1.686: [GC 1805K->1238K(5056K), 0.0034732 secs] 1.690: [Full GC 1238K->1238K(5056K), 0.0631661 secs] 1.874: [GC 62133K->61257K(65060K), 0.0014464 secs]

The accepted answer above:

Didn't work for me exactly. I only was able to successfully change my timezone when I didn't have quotes around the parameters:

I fixed a similar issue building a RadioButtonFor with pairs of text/value from a SelectList. I used a ViewBag to send the SelectList to the View, but you can use data from model too. My web application is a Blog and I have to build a RadioButton with some types of articles when he is writing a new post.
The code below was simplyfied.
List<SelectListItem> items = new List<SelectListItem>();
Dictionary<string, string> dictionary = new Dictionary<string, string>();
dictionary.Add("Texto", "1");
dictionary.Add("Foto", "2");
dictionary.Add("Vídeo", "3");
foreach (KeyValuePair<string, string> pair in objBLL.GetTiposPost())
{
items.Add(new SelectListItem() { Text = pair.Key, Value = pair.Value, Selected = false });
}
ViewBag.TiposPost = new SelectList(items, "Value", "Text");
In the View, I used a foreach to build a radiobutton.
<div class="form-group">
<div class="col-sm-10">
@foreach (var item in (SelectList)ViewBag.TiposPost)
{
@Html.RadioButtonFor(model => model.IDTipoPost, item.Value, false)
<label class="control-label">@item.Text</label>
}
</div>
</div>
Notice that I used RadioButtonFor in order to catch the option value selected by user, in the Controler, after submit the form. I also had to put the item.Text outside the RadioButtonFor in order to show the text options.
Hope it's useful!
One easy way to accomplish this is combining what was posted in the original post into a single statement:
int numberOfRecords = dtFoo.Select("IsActive = 'Y'").Length;
Another way to accomplish this is using Linq methods:
int numberOfRecords = dtFoo.AsEnumerable().Where(x => x["IsActive"].ToString() == "Y").ToList().Count;
Note this requires including System.Linq
.
Another option, not necesarily more elegant, but does not require to refer to a specific column:
mtcars %>%
group_by(cyl, gear) %>%
do(data.frame(nrow=nrow(.)))
Mark's idea was good, but maybe forgot some path have spaces in them. Replacing ';' with '" "' instead would cut all paths into quoted strings.
set _path="%PATH:;=" "%"
for %%p in (%_path%) do if not "%%~p"=="" echo %%~p
So here, you have your paths displayed.
FOR command in cmd has a tedious learning curve, notably because how variables react within ()'s statements... you can assign any variables, but you can't read then back within the ()'s, unless you use the "setlocal ENABLEDELAYEDEXPANSION" statement, and therefore also use the variables with !!'s instead of %%'s (!_var!)
I currently exclusively script with cmd, for work, had to learn all this :)
The --no-ff
option is useful when you want to have a clear notion of your feature branch. So even if in the meantime no commits were made, FF is possible - you still want sometimes to have each commit in the mainline correspond to one feature. So you treat a feature branch with a bunch of commits as a single unit, and merge them as a single unit. It is clear from your history when you do feature branch merging with --no-ff
.
If you do not care about such thing - you could probably get away with FF whenever it is possible. Thus you will have more svn-like feeling of workflow.
For example, the author of this article thinks that --no-ff
option should be default and his reasoning is close to that I outlined above:
Consider the situation where a series of minor commits on the "feature" branch collectively make up one new feature: If you just do "git merge feature_branch" without --no-ff
, "it is impossible to see from the Git history which of the commit objects together have implemented a feature—you would have to manually read all the log messages. Reverting a whole feature (i.e. a group of commits), is a true headache [if --no-ff
is not used], whereas it is easily done if the --no-ff
flag was used [because it's just one commit]."
I implemented access using the following
class D(Enum):
x = 1
y = 2
def __str__(self):
return '%s' % self.value
now I can just do
print(D.x)
to get 1
as result.
You can also use self.name
in case you wanted to print x
instead of 1
.
Use clear: both;
I spent over a week trying to figure this out!
package com.beans;
public class Flower{
.......
}
packages :=> com.beans,
java class Name:=> Flower.java,
Folder structure (assuming):=> C:\com\beans\Flower.*(both .java/.class exist here)
then there are two ways of executing it:
1. Goto top Folder (here its C:\>),
then : C:> java com.beans.Flower
2. Executing from innermost folder "beans" here (C:\com\beans:>),
then: C:\com\beans:> java -cp ./../.. com.beans.Flower

if the applications are C#, you can use ClickOnce deployment, which is a good option if you can't guarentee the user will have the app, however you'll have to re-build the apps with deployment options and grab some boilerplate code from each project.
You can also use Javascript.
Or you can register an application to handle a new web protocol you can define. This could also be an "app selection" protocol, so each time an app is clicked it would link to a page on your new protocol, all handling of this protocol is then passed to your "selection app" which uses arguments to find and launch an app on the clients PC.

if you are using ps, you can check the manual
man ps
there is a list of keywords allowing you to build what you need. for example to show, userid / processid / percent cpu / percent memory / work queue / command :
ps -e -o "uid pid pcpu pmem wq comm"
-e is similar to -A (all inclusive; your processes and others), and -o is to force a format.
if you are looking for a specific uid, you can chain it using awk or grep such as :
ps -e -o "uid pid pcpu pmem wq comm" | grep 501
this should (almost) show only for userid 501. try it.
The Permanent Generation (PermGen) space has completely been removed and is kind of replaced by a new space called Metaspace.The consequences of the PermGen removal is that obviously the PermSize and MaxPermSize JVM arguments are ignored and you will never get a java.lang.OutOfMemoryError
: PermGen error.
The JDK 8 HotSpot JVM is now using native memory for the representation of class metadata and is called Metaspace. Read More>>
Adding on to Kalyoyan's answer, this subscription is tied to the router and will live until the page is fully refreshed. When subscribing to router events in a component, be sure to unsubscribe in ngOnDestroy:
import { OnDestroy } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';
import { Subscription } from "rxjs/Rx";
class MyAppComponent implements OnDestroy {
private subscription: Subscription;
constructor(router: Router) {
this.subscription = router.events.subscribe(s => {
if (s instanceof NavigationEnd) {
const tree = router.parseUrl(router.url);
if (tree.fragment) {
const element = document.querySelector("#" + tree.fragment);
if (element) { element.scrollIntoView(element); }
}
}
});
}
public ngOnDestroy() {
this.subscription.unsubscribe();
}
}
ANother option could be to post the image to a webapp (possibly at a later moment), and have it OCR-processed there without the C++ -> Java port issues and possibly clogging the mobile CPU.
If you're working with an asp.net application and you want to locate assemblies when using the debugger, they are usually put into some temp directory. I wrote the this method to help with that scenario.
private string[] GetAssembly(string[] assemblyNames)
{
string [] locations = new string[assemblyNames.Length];
for (int loop = 0; loop <= assemblyNames.Length - 1; loop++)
{
locations[loop] = AppDomain.CurrentDomain.GetAssemblies().Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop]).Select(a => a.Location).FirstOrDefault();
}
return locations;
}

If you can't change the source code, or redeploy, but you can examine the running processes on the computer use Process Explorer. I written a detailed description here.
It will list all executing dlls on the system, you may need to determine the process id of your running application, but that is usually not too difficult.
I've written a full description of how do this for a dll inside IIS - http://nodogmablog.bryanhogan.net/2016/09/locating-and-checking-an-executing-dll-on-a-running-web-server/
For 8085: Stack pointer is a special purpose 16-bit register in the Microprocessor, which holds the address of the top of the stack.
The stack pointer register in a computer is made available for general purpose use by programs executing at lower privilege levels than interrupt handlers. A set of instructions in such programs, excluding stack operations, stores data other than the stack pointer, such as operands, and the like, in the stack pointer register. When switching execution to an interrupt handler on an interrupt, return address data for the currently executing program is pushed onto a stack at the interrupt handler's privilege level. Thus, storing other data in the stack pointer register does not result in stack corruption. Also, these instructions can store data in a scratch portion of a stack segment beyond the current stack pointer.

One useful trick in SQL is the ability use @var = function(...)
to assign a value. If you have multiple records in your record set, your var is assigned multiple times with side-effects:
declare @badStrings table (item varchar(50))
INSERT INTO @badStrings(item)
SELECT '>' UNION ALL
SELECT '<' UNION ALL
SELECT '(' UNION ALL
SELECT ')' UNION ALL
SELECT '!' UNION ALL
SELECT '?' UNION ALL
SELECT '@'
declare @testString varchar(100), @newString varchar(100)
set @teststring = 'Juliet ro><0zs my s0x()rz!!?!one!@!@!@!'
set @newString = @testString
SELECT @newString = Replace(@newString, item, '') FROM @badStrings
select @newString -- returns 'Juliet ro0zs my s0xrzone'
I'm no Git master, but from searching around the solution that worked easiest for me was to just go to C:\Program Files (x86)\Git\etc
and open profile
in a text editor.
There's an if
statement on line 37 # Set up USER's home directory
. I took out the if
statement and put in the local directory that I wanted the gitconfig to be, then I just copied my existing gitconfig file (was on a network drive) to that location.
You probably want to have LI rather than the UL have the background-color:
.selected li {
background-color: red;
}
Then you want to have a dynamic class for the UL:
<ul ng-repeat="vote in votes" ng-click="setSelected()" class="{{selected}}">
Now you need to update the $scope.selected when clicking the row:
$scope.setSelected = function() {
console.log("show", arguments, this);
this.selected = 'selected';
}
and then un-select the previously highlighted row:
$scope.setSelected = function() {
// console.log("show", arguments, this);
if ($scope.lastSelected) {
$scope.lastSelected.selected = '';
}
this.selected = 'selected';
$scope.lastSelected = this;
}
Working solution:
Checking the install state for the product via MsiQueryProductState is pretty much equivalent to checking the registry directly, but you still need the GUID for the ProductCode.
As mentioned elsewhere, one drawback with these approaches is that each update has its own ProductCode!
Thankfully, MSI provides an UpgradeCode which identifies a 'family' of products. You can use orca to open up one of the MSIs to extract this information. For example, the UpgradeCode for VS2015's redistributable is {65E5BD06-6392-3027-8C26-853107D3CF1A}
You can use MsiEnumRelatedProducts to get all Product IDs for that UpgradeCode. In practice, since each redist update replaces the previous one, this will only yield one ProductCode - such as {B5FC62F5-A367-37A5-9FD2-A6E137C0096F}
for VS2015 Update 2 x86.
Regardless, you can then check the version via MsiGetProductInfo(productCode, INSTALLPROPERTY_VERSIONSTRING, ...) or similar functions to compare with the version you want, eg to check for an equivalent or later version.
Note that within a C++ application, you can also use _VC_CRT_MAJOR_VERSION
, _VC_CRT_MINOR_VERSION
, _VC_CRT_BUILD_VERSION
if you #include <crtversion.h>
-- this way you can determine calculate the CRT version that your binary was built with.
I would use JodaTime for this. Here is an example - lets say you want to find the difference in days between 2 dates.
DateTime startDate = new DateTime(some_date);
DateTime endDate = new DateTime(); //current date
Days diff = Days.daysBetween(startDate, endDate);
System.out.println(diff.getDays());
JodaTime can be downloaded from here.

Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.
For pure characters-of-code efficiency, I can't find anything better than
smallest = a<b&&a<c?a:b<c?b:c;
If you think all those prototype definitions, array creations, and join operations are overkill, just use a single line code where you need it. String S repeating N times:
for (var i = 0, result = ''; i < N; i++) result += S;
So do the following ,
Lets say your branch name is my_branch and this has the extra commits.
git checkout -b my_branch_with_extra_commits
(Keeping this branch saved under a different name)gitk
(Opens git console)git checkout my_branch
gitk
(This will open the git console )reset branch to here
" git pull --rebase origin branch_name_to _merge_to
git cherry-pick <SHA you copied in step 3. >
Now look at the local branch commit history and make sure everything looks good.
The proper way to do it is by using tput
or terminfo
functions to obtain terminal properties and then insert newlines according to the dimensions..
Actually you can still have a Map
with the original keys after converting to array with Array.from
. That's possible by returning an array, where the first item is the key
, and the second is the transformed value
.
const originalMap = new Map([
["thing1", 1], ["thing2", 2], ["thing3", 3]
]);
const arrayMap = Array.from(originalMap, ([key, value]) => {
return [key, value + 1]; // return an array
});
const alteredMap = new Map(arrayMap);
console.log(originalMap); // Map { 'thing1' => 1, 'thing2' => 2, 'thing3' => 3 }
console.log(alteredMap); // Map { 'thing1' => 2, 'thing2' => 3, 'thing3' => 4 }
If you don't return that key as the first array item, you loose your Map
keys.
View -> Datasets (bottom of menu, above Refresh)
Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:
<xsl:template match="class">
<xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
<xsl:variable name="subexists">
<xsl:choose>
<xsl:when test="joined-subclass">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:variable>
subexists: <xsl:value-of select="$subexists" />
</xsl:template>
And if you need the variable to have "global" scope then declare it outside of the template:
<xsl:variable name="subexists">
<xsl:choose>
<xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
<xsl:otherwise>false</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:template match="class">
subexists: <xsl:value-of select="$subexists" />
</xsl:template>
Also, you can display current position by "drag" listener and write it to visible or hidden field. You may also need to store zoom. Here's copy&paste from working tool:
function map_init() {
var lt=48.451778;
var lg=31.646305;
var myLatlng = new google.maps.LatLng(lt,lg);
var mapOptions = {
center: new google.maps.LatLng(lt,lg),
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map'),mapOptions);
var marker = new google.maps.Marker({
position:myLatlng,
map:map,
draggable:true
});
google.maps.event.addListener(
marker,
'drag',
function() {
document.getElementById('lat1').innerHTML = marker.position.lat().toFixed(6);
document.getElementById('lng1').innerHTML = marker.position.lng().toFixed(6);
document.getElementById('zoom').innerHTML = mapObject.getZoom();
// Dynamically show it somewhere if needed
$(".x").text(marker.position.lat().toFixed(6));
$(".y").text(marker.position.lng().toFixed(6));
$(".z").text(map.getZoom());
}
);
}
The code to compress/decompress a string
public static void CopyTo(Stream src, Stream dest) {
byte[] bytes = new byte[4096];
int cnt;
while ((cnt = src.Read(bytes, 0, bytes.Length)) != 0) {
dest.Write(bytes, 0, cnt);
}
}
public static byte[] Zip(string str) {
var bytes = Encoding.UTF8.GetBytes(str);
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream()) {
using (var gs = new GZipStream(mso, CompressionMode.Compress)) {
//msi.CopyTo(gs);
CopyTo(msi, gs);
}
return mso.ToArray();
}
}
public static string Unzip(byte[] bytes) {
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream()) {
using (var gs = new GZipStream(msi, CompressionMode.Decompress)) {
//gs.CopyTo(mso);
CopyTo(gs, mso);
}
return Encoding.UTF8.GetString(mso.ToArray());
}
}
static void Main(string[] args) {
byte[] r1 = Zip("StringStringStringStringStringStringStringStringStringStringStringStringStringString");
string r2 = Unzip(r1);
}
Remember that Zip
returns a byte[]
, while Unzip
returns a string
. If you want a string from Zip
you can Base64 encode it (for example by using Convert.ToBase64String(r1)
) (the result of Zip
is VERY binary! It isn't something you can print to the screen or write directly in an XML)
The version suggested is for .NET 2.0, for .NET 4.0 use the MemoryStream.CopyTo
.
IMPORTANT: The compressed contents cannot be written to the output stream until the GZipStream
knows that it has all of the input (i.e., to effectively compress it needs all of the data). You need to make sure that you Dispose()
of the GZipStream
before inspecting the output stream (e.g., mso.ToArray()
). This is done with the using() { }
block above. Note that the GZipStream
is the innermost block and the contents are accessed outside of it. The same goes for decompressing: Dispose()
of the GZipStream
before attempting to access the data.
It is a little difficult to answer your specific question without a full, reproducible example. However something like this should work:
#Turn your 'treatment' column into a character vector
data$Treatment <- as.character(data$Treatment)
#Then turn it back into a factor with the levels in the correct order
data$Treatment <- factor(data$Treatment, levels=unique(data$Treatment))
In this example, the order of the factor will be the same as in the data.csv
file.
If you prefer a different order, you can order them by hand:
data$Treatment <- factor(data$Treatment, levels=c("Y", "X", "Z"))
However this is dangerous if you have a lot of levels: if you get any of them wrong, that will cause problems.
The double '%' works also in ".Format(…).
Example (with iDrawApertureMask == 87, fCornerRadMask == 0.05):
csCurrentLine.Format("\%ADD%2d%C,%6.4f*\%",iDrawApertureMask,fCornerRadMask) ;
gives the desired and expected value of (string contents in) csCurrentLine;
"%ADD87C, 0.0500*%"
Set args = Wscript.Arguments
For Each arg In args
Wscript.Echo arg
Next
From a command prompt, run the script like this:
CSCRIPT MyScript.vbs 1 2 A B "Arg with spaces"
Will give results like this:
1
2
A
B
Arg with spaces
Multiple SQL statements must be executed with the mysqli_multi_query()
function.
Example (MySQLi Object-oriented):
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";
if ($conn->multi_query($sql) === TRUE) {
echo "New records created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
I always use the ISO 8601 format (e.g. 2008-10-31T15:07:38.6875000-05:00
) -- date.ToString("o")
. It is the XSD date format as well. That is the preferred format and a Standard Date and Time Format string, although you can use a manual format string if necessary if you don't want the 'T' between the date and time: date.ToString("yyyy-MM-dd HH:mm:ss");
EDIT: If you are using a generated class from an XSD or Web Service, you can just assign the DateTime instance directly to the class property. If you are writing XML text, then use the above.
In Arduino:
//temporarily holds data from vals
char charVal[10];
//4 is mininum width, 3 is precision; float value is copied onto buff
dtostrf(123.234, 4, 3, charVal);
monitor.print("charVal: ");
monitor.println(charVal);
Unfortunately, what you want is not possible with Python (which makes Python close to useless for command-line one-liner programs). Even explicit use of parentheses does not avoid the syntax exception. You can get away with a sequence of simple statements, separated by semi-colon:
for i in range(10): print "foo"; print "bar"
But as soon as you add a construct that introduces an indented block (like if
), you need the line break. Also,
for i in range(10): print "i equals 9" if i==9 else None
is legal and might approximate what you want.
As for the try ... except
thing: It would be totally useless without the except
. try
says "I want to run this code, but it might throw an exception". If you don't care about the exception, leave away the try
. But as soon as you put it in, you're saying "I want to handle a potential exception". The pass
then says you wish to not handle it specifically. But that means your code will continue running, which it wouldn't otherwise.
With google's Gson 2.7 (probably earlier versions too, but I tested 2.7) it's as simple as:
Map map = gson.fromJson(json, Map.class);
Which returns a Map of type class com.google.gson.internal.LinkedTreeMap
and works recursively on nested objects.
You can extract the html string from the PartialViewResult object, similar to the answer to this thread:
PartialViewResult and ViewResult both derive from ViewResultBase, so the same method should work on both.
Using the code from the thread above, you would be able to use:
public ActionResult ReturnSpecialJsonIfInvalid(AwesomenessModel model)
{
if (ModelState.IsValid)
{
if(Request.IsAjaxRequest())
return PartialView("NotEvil", model);
return View(model)
}
if(Request.IsAjaxRequest())
{
return Json(new { error = true, message = RenderViewToString(PartialView("Evil", model))});
}
return View(model);
}
For Angular use:
ng-required="boolean"
This will only apply the html5 'required' attribute if the value is true.
<input ng-model="myCtrl.item" ng-required="myCtrl.items > 0" />
Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express
(%PROGRAMFILES(x86)%\IIS Express
on x64 architectures) and its called iisexpress.exe
.
To see all the possible command-line options, just run:
iisexpress /?
and the program detailed help will show up.
If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.
There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config
): the /site
and /siteId
.
With the first one, you can launch a specific site by name:
iisexpress /site:SiteName
And with the latter, you can launch by specifying the ID:
iisexpress /siteId:SiteId
With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.
Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):
iisexpress /path:FullSitePath
This covers the basic IISExpress usage from the command line.
It seems to me like you could just check for !stream.paused
.

I used KooiInc's function listed above but I had to use two different input types one 'button' for IE and one 'submit' for FireFox. I am not exactly sure why but it works.
// HTML
<input type="button" id="btnEmailHidden" style="display:none" />
<input type="submit" id="btnEmailHidden2" style="display:none" />
// in JavaScript
var hiddenBtn = document.getElementById("btnEmailHidden");
if (hiddenBtn.fireEvent) {
hiddenBtn.fireEvent('onclick');
hiddenBtn[eType]();
}
else {
// dispatch for firefox + others
var evObj = document.createEvent('MouseEvent');
evObj.initEvent(eType, true, true);
var hiddenBtn2 = document.getElementById("btnEmailHidden2");
hiddenBtn2.dispatchEvent(evObj);
}
I have search and tried many suggestions but this is what ended up working. If I had some more time I would have liked to investigate why submit works with FF and button with IE but that would be a luxury right now so on to the next problem.
What you probably want is dir()
.
The catch is that classes are able to override the special __dir__
method, which causes dir()
to return whatever the class wants (though they are encouraged to return an accurate list, this is not enforced). Furthermore, some objects may implement dynamic attributes by overriding __getattr__
, may be RPC proxy objects, or may be instances of C-extension classes. If your object is one these examples, they may not have a __dict__
or be able to provide a comprehensive list of attributes via __dir__
: many of these objects may have so many dynamic attrs it doesn't won't actually know what it has until you try to access it.
In the short run, if dir()
isn't sufficient, you could write a function which traverses __dict__
for an object, then __dict__
for all the classes in obj.__class__.__mro__
; though this will only work for normal python objects. In the long run, you may have to use duck typing + assumptions - if it looks like a duck, cross your fingers, and hope it has .feathers
.
Check this validation library Files : http://bassistance.de/jquery-plugins/jquery-plugin-validation/ Demo : http://jquery.bassistance.de/validate/demo/
If anyone comes looking to create a similar JSON, just without using cart
as an array, here goes:
I have an array of objects myArr
as:
var myArr = [{resourceType:"myRT",
id: 1,
value:"ha"},
{resourceType:"myRT",
id: 2,
value:"he"},
{resourceType:"myRT",
id: 3,
value:"Li"}];
and I will attempt to create a JSON with the following structure:
{
"1":{"resourceType":"myRT","id":"1","value":"ha"},
"2":{"resourceType":"myRT","id":"2","value":"he"},
"3":{"resourceType":"myRT","id":"3","value":"Li"}
}
you can simply do-
var cart = {};
myArr.map(function(myObj){
cart[myObj.id]= myObj;
});
This type of situation is implementation dependent and consequently it will require a vendor specific mechanism in order to trap. With Microsoft this will involve SEH, and *nix will involve a signal
In general though catching an Access Violation exception is a very bad idea. There is almost no way to recover from an AV exception and attempting to do so will just lead to harder to find bugs in your program.
It seems they offer a js
option for the format parameter, which will return JSONP. You can retrieve JSONP like so:
function getJSONP(url, success) {
var ud = '_' + +new Date,
script = document.createElement('script'),
head = document.getElementsByTagName('head')[0]
|| document.documentElement;
window[ud] = function(data) {
head.removeChild(script);
success && success(data);
};
script.src = url.replace('callback=?', 'callback=' + ud);
head.appendChild(script);
}
getJSONP('http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=?', function(data){
console.log(data);
});
$final_array = array_combine($a, $a);
Reference: http://php.net/array-combine
P.S. Be careful with source array containing duplicated keys like the following:
$a = ['one','two','one'];
Note the duplicated one
element.
String scriptName = PATH+"/myScript.sh";
String commands[] = new String[]{scriptName,"myArg1", "myArg2"};
Runtime rt = Runtime.getRuntime();
Process process = null;
try{
process = rt.exec(commands);
process.waitFor();
}catch(Exception e){
e.printStackTrace();
}
If you want query parameters, you use @QueryParam
.
public Todo getXML(@QueryParam("summary") String x,
@QueryParam("description") String y)
But you won't be able to send a PUT from a plain web browser (today). If you type in the URL directly, it will be a GET.
Philosophically, this looks like it should be a POST, though. In REST, you typically either POST to a common resource, /todo
, where that resource creates and returns a new resource, or you PUT to a specifically-identified resource, like /todo/<id>
, for creation and/or update.
+ theme(plot.title = element_text(size=22))
Here is the full set of things you can change in element_text
:
element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
color = NULL)
You can do and
with nested conditions:
if %age% geq 2 (
if %age% leq 12 (
set class=child
)
)
or:
if %age% geq 2 if %age% leq 12 set class=child
You can do or
with a separate variable:
set res=F
if %hour% leq 6 set res=T
if %hour% geq 22 set res=T
if "%res%"=="T" (
set state=asleep
)
Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.
So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.
cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit
But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.
@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit
Or if you'd like them to select the file from which to write in the batch you could do the following.
@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit
Here is a version of the currently accepted answer (from @Trevor) with key instead of keyCode:
document.querySelector('#txtSearch').addEventListener('keypress', function (e) {
if (e.key === 'Enter') {
// code for enter
}
});
you'd better reference angular document, becuase the version[1.4.9] has update to below that make it could support data-ng-cloak directive.
[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
display: none !important;
}
yum install python34-pip
pip3.4 install foo
You will likely need the EPEL repositories installed:
yum install -y epel-release
The below command will get all the file names from your AWS S3 bucket and write into text file in your current directory:
aws s3 ls s3://Bucketdirectory/Subdirectory/ | cat >> FileNames.txt
Ecmascript 6 includes "destructuring assignments" (as kangax mentioned) so in all browsers (not just Firefox) you'll be able to capture an array of values without having to make a named array or object for the sole purpose of capturing them.
//so to capture from this function
function myfunction()
{
var n=0;var s=1;var w=2;var e=3;
return [n,s,w,e];
}
//instead of having to make a named array or object like this
var IexistJusttoCapture = new Array();
IexistJusttoCapture = myfunction();
north=IexistJusttoCapture[0];
south=IexistJusttoCapture[1];
west=IexistJusttoCapture[2];
east=IexistJusttoCapture[3];
//you'll be able to just do this
[north, south, west, east] = myfunction();
You can try it out in Firefox already!
I assume you are using windows. Open the command prompt and type ipconfig
and find out your local address (on your pc) it should look something like 192.168.1.13
or 192.168.0.5
where the end digit is the one that changes. It should be next to IPv4 Address.
If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13
If you have a virtual host then you will need root to edit the hosts file.
If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.
See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.
Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).
If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow
to allow,deny
in the httpd.conf
file. You can access this by the WAMP menu.
To eliminate possible causes of the issue for now set your config file to
<Directory />
Options FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
<RequireAll>
Require all granted
</RequireAll>
</Directory>
As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.
Config file that fixed the problem:
https://gist.github.com/samvaughton/6790739
Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.
For Windows, first install the git base from here: https://git-scm.com/downloads
Next, set the environment variable:
C:\Program Files\Git\git-bash.exe
To test it, open the command window: press Windows+R, type cmd and then type ssh.
You can do this entirely with bash 4.3
and above:
_timeout() { ( set +b; sleep "$1" & "${@:2}" & wait -n; r=$?; kill -9 `jobs -p`; exit $r; ) }
_timeout 5 longrunning_command args
{ _timeout 5 producer || echo KABOOM $?; } | consumer
producer | { _timeout 5 consumer1; consumer2; }
Example: { while date; do sleep .3; done; } | _timeout 5 cat | less
Needs Bash 4.3 for wait -n
If you do not need the return code, this can be made even simpler:
_timeout() { ( set +b; sleep "$1" & "${@:2}" & wait -n; kill -9 `jobs -p`; ) }
Notes:
Strictly speaking you do not need the ;
in ; )
, however it makes thing more consistent to the ; }
-case. And the set +b
probably can be left away, too, but better safe than sorry.
Except for --forground
(probably) you can implement all variants timeout
supports. --preserve-status
is a bit difficult, though. This is left as an exercise for the reader ;)
This recipe can be used "naturally" in the shell (as natural as for flock fd
):
(
set +b
sleep 20 &
{
YOUR SHELL CODE HERE
} &
wait -n
kill `jobs -p`
)
However, as explained above, you cannot re-export environment variables into the enclosing shell this way naturally.
Edit:
Real world example: Time out __git_ps1
in case it takes too long (for things like slow SSHFS-Links):
eval "__orig$(declare -f __git_ps1)" && __git_ps1() { ( git() { _timeout 0.3 /usr/bin/git "$@"; }; _timeout 0.3 __orig__git_ps1 "$@"; ) }
Edit2: Bugfix. I noticed that exit 137
is not needed and makes _timeout
unreliable at the same time.
Edit3: git
is a die-hard, so it needs a double-trick to work satisfyingly.
Edit4: Forgot a _
in the first _timeout
for the real world GIT example.

You can replace the jquery load function with a version that has cache set to false.
(function($) {
var _load = jQuery.fn.load;
$.fn.load = function(url, params, callback) {
if ( typeof url !== "string" && _load ) {
return _load.apply( this, arguments );
}
var selector, type, response,
self = this,
off = url.indexOf(" ");
if (off > -1) {
selector = stripAndCollapse(url.slice(off));
url = url.slice(0, off);
}
// If it's a function
if (jQuery.isFunction(params)) {
// We assume that it's the callback
callback = params;
params = undefined;
// Otherwise, build a param string
} else if (params && typeof params === "object") {
type = "POST";
}
// If we have elements to modify, make the request
if (self.length > 0) {
jQuery.ajax({
url: url,
// If "type" variable is undefined, then "GET" method will be used.
// Make value of this field explicit since
// user can override it through ajaxSetup method
type: type || "GET",
dataType: "html",
cache: false,
data: params
}).done(function(responseText) {
// Save response for use in complete callback
response = arguments;
self.html(selector ?
// If a selector was specified, locate the right elements in a dummy div
// Exclude scripts to avoid IE 'Permission Denied' errors
jQuery("<div>").append(jQuery.parseHTML(responseText)).find(selector) :
// Otherwise use the full result
responseText);
// If the request succeeds, this function gets "data", "status", "jqXHR"
// but they are ignored because response was set above.
// If it fails, this function gets "jqXHR", "status", "error"
}).always(callback && function(jqXHR, status) {
self.each(function() {
callback.apply(this, response || [jqXHR.responseText, status, jqXHR]);
});
});
}
return this;
}
})(jQuery);
Place this somewhere global where it will run after jquery loads and you should be all set. Your existing load code will no longer be cached.
Similar answer to iHulk's one, but in Swift
Add a file named UIView.swift in your project (or just paste this in any file) :
import UIKit
@IBDesignable extension UIView {
@IBInspectable var borderColor: UIColor? {
set {
layer.borderColor = newValue?.cgColor
}
get {
guard let color = layer.borderColor else {
return nil
}
return UIColor(cgColor: color)
}
}
@IBInspectable var borderWidth: CGFloat {
set {
layer.borderWidth = newValue
}
get {
return layer.borderWidth
}
}
@IBInspectable var cornerRadius: CGFloat {
set {
layer.cornerRadius = newValue
clipsToBounds = newValue > 0
}
get {
return layer.cornerRadius
}
}
}
Then this will be available in Interface Builder for every button, imageView, label, etc. in the Utilities Panel > Attributes Inspector :
Note: the border will only appear at runtime.
Neither of these answers would work for me, not the Preferences NLS configuration option or the ALTER statement. This was the only approach that worked in my case:
dbms_session.set_nls('nls_date_format','''DD-MM-YYYY HH24:MI:SS''');
*added after the BEGIN statement
I am using PL/SQL Developer v9.03.1641
Hopefully this is of help to someone!
This is probably unpopular way. But here how I do it:
object1 = // object to copy
YourClass *object2 = [[YourClass alloc] init];
object2.property1 = object1.property1;
object2.property2 = object1.property2;
..
etc.
Quite simple and straight forward. :P
I recommend using passthru
and handling the output buffer directly:
ob_start();
passthru('/usr/bin/python2.7 /srv/http/assets/py/switch.py arg1 arg2');
$output = ob_get_clean();
Like the other answers say, you can't remove an item from a collection you're iterating over. You can get around this by explicitly using an Iterator
and removing the item there.
Iterator<Item> iter = list.iterator();
while(iter.hasNext()) {
Item blah = iter.next();
if(...) {
iter.remove(); // Removes the 'current' item
}
}
random.rand
is deprecated meanwhile.This works with matplotlip 3.2.1:
from matplotlib import pyplot as plt
import random
import numpy as np
random = np.random.random ([8,90])
plt.figure(figsize = (20,2))
plt.imshow(random, interpolation='nearest')
This plots:
To change the random number, you can experiment with np.random.normal(0,1,(8,90))
(here mean = 0, standard deviation = 1).
If you are using Photoshop go File > Save for web (Command + Option + Shift + S). Make sure the Transparency is unchecked and this should work.
You need to do 2 things :
1) Call setPreventCornerOverlap(false)
on your CardView.
2) Put rounded Imageview inside CardView
About rounding your imageview, I had the same problem so I made a library that you can set different radii on each corner. Finally I got the result what I wanted like below.
There are different ways. If you just want to check if one list contains any element from the other list, you can do this..

I can´t answer your question in the comments due to low reputation score.
The next code will give you an error because the paste function return a character string
for(i in 1:length(var.out)) {
paste("data$", var.out[i], sep="") <- NULL
}
Here is a possible solution:
for(i in 1:length(var.out)) {
text_to_source <- paste0 ("data$", var.out[i], "<- NULL") # Write a line of your
# code like a character string
eval (parse (text=text_to_source)) # Source a text that contains a code
}
or just do:
for(i in 1:length(var.out)) {
data[var.out[i]] <- NULL
}
Install Git for windows Then use git bash to run curl commands.
Please show us more parts of the script and tell us what commands you had to individually execute and want to simply.
Meanwhile you have to use double quotes not single quote to expand variables:
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
Semicolons at the end of a single command are also unnecessary.
So far:
#!/bin/sh
echo "Perform Operation in su mode"
export ARCH=arm
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...
For su
you can run it with:
su -c 'sh /path/to/script.sh'
Note: The OP was not explicitly asking for steps on how to create export variables in an interactive shell using a shell script. He only asked his script to be assessed at most. He didn't mention details on how his script would be used. It could have been by using .
or source
from the interactive shell. It could have been a standalone scipt, or it could have been source
'd from another script. Environment variables are not specific to interactive shells. This answer solved his problem.
I think you want this syntax:
ALTER TABLE tb_TableName
add constraint cnt_Record_Status Default '' for Record_Status
Based on some of your comments, I am going to guess that you might already have null
values in your table which is causing the alter of the column to not null
to fail. If that is the case, then you should run an UPDATE
first. Your script will be:
update tb_TableName
set Record_Status = ''
where Record_Status is null
ALTER TABLE tb_TableName
ALTER COLUMN Record_Status VARCHAR(20) NOT NULL
ALTER TABLE tb_TableName
ADD CONSTRAINT DEF_Name DEFAULT '' FOR Record_Status
Late to the party I know.
I use this:
public static string GetPropertyDisplayName(PropertyInfo pi)
{
var dp = pi.GetCustomAttributes(typeof(DisplayNameAttribute), true).Cast<DisplayNameAttribute>().SingleOrDefault();
return dp != null ? dp.DisplayName : pi.Name;
}
Hope this helps.
You can use int casting which allows the base specification.
int(b, 2) # Convert a binary string to a decimal int.
You can wrap your table around the div tag like this as it helped me too.
<div class="col-md-3">
<table>
</table>
</div>
You need to have your variables exported. So for example in Linux:
export EnvironmentVariableName=foo
Unexported variables are empty in CMAKE.
Same functionality i recently achieved using below function.

$(':text').keypress(function(e) { // text written
enableSaveBtn();

enableSaveBtn();
} else { // rest ignore
e.preventDefault();

Little bit off topic but say i want to remove all 2s from a list. Here's a very elegant way to do that.
void RemoveAll<T>(T item,List<T> list)
{
while(list.Contains(item)) list.Remove(item);
}
With predicate:
void RemoveAll<T>(Func<T,bool> predicate,List<T> list)
{
while(list.Any(predicate)) list.Remove(list.First(predicate));
}
+1 only to encourage you to leave your answer here for learning purposes. You're also right about it being off-topic, but I won't ding you for that because of there is significant value in leaving your examples here, again, strictly for learning purposes. I'm posting this response as an edit because posting it as a series of comments would be unruly.
Though your examples are short & compact, neither is elegant in terms of efficiency; the first is bad at O(n2), the second, absolutely abysmal at O(n3). Algorithmic efficiency of O(n2) is bad and should be avoided whenever possible, especially in general-purpose code; efficiency of O(n3) is horrible and should be avoided in all cases except when you know n will always be very small. Some might fling out their "premature optimization is the root of all evil" battle axes, but they do so naïvely because they do not truly understand the consequences of quadratic growth since they've never coded algorithms that have to process large datasets. As a result, their small-dataset-handling algorithms just run generally slower than they could, and they have no idea that they could run faster. The difference between an efficient algorithm and an inefficient algorithm is often subtle, but the performance difference can be dramatic. The key to understanding the performance of your algorithm is to understand the performance characteristics of the primitives you choose to use.
In your first example, list.Contains()
and Remove()
are both O(n), so a while()
loop with one in the predicate & the other in the body is O(n2); well, technically O(m*n), but it approaches O(n2) as the number of elements being removed (m) approaches the length of the list (n).
Your second example is even worse: O(n3), because for every time you call Remove()
, you also call First(predicate)
, which is also O(n). Think about it: Any(predicate)
loops over the list looking for any element for which predicate()
returns true. Once it finds the first such element, it returns true. In the body of the while()
loop, you then call list.First(predicate)
which loops over the list a second time looking for the same element that had already been found by list.Any(predicate)
. Once First()
has found it, it returns that element which is passed to list.Remove()
, which loops over the list a third time to yet once again find that same element that was previously found by Any()
and First()
, in order to finally remove it. Once removed, the whole process starts over at the beginning with a slightly shorter list, doing all the looping over and over and over again starting at the beginning every time until finally no more elements matching the predicate remain. So the performance of your second example is O(m*m*n), or O(n3) as m approaches n.
Your best bet for removing all items from a list that match some predicate is to use the generic list's own List<T>.RemoveAll(predicate)
method, which is O(n) as long as your predicate is O(1). A for()
loop technique that passes over the list only once, calling list.RemoveAt()
for each element to be removed, may seem to be O(n) since it appears to pass over the loop only once. Such a solution is more efficient than your first example, but only by a constant factor, which in terms of algorithmic efficiency is negligible. Even a for()
loop implementation is O(m*n) since each call to Remove()
is O(n). Since the for()
loop itself is O(n), and it calls Remove()
m times, the for()
loop's growth is O(n2) as m approaches n.
Below code works: but not very efficient way. :(
static void Main(String[] args) {
int n = Convert.ToInt32(Console.ReadLine());
int[] medList = new int[n];
for (int x = 0; x < n; x++)
medList[x] = int.Parse(Console.ReadLine());
//sort the input array:
//Array.Sort(medList);
for (int x = 0; x < n; x++)
{
double[] newArr = new double[x + 1];
for (int y = 0; y <= x; y++)
newArr[y] = medList[y];
Array.Sort(newArr);
int curInd = x + 1;
if (curInd % 2 == 0) //even
{
int mid = (x / 2) <= 0 ? 0 : (newArr.Length / 2);
if (mid > 1) mid--;
double median = (newArr[mid] + newArr[mid+1]) / 2;
Console.WriteLine("{0:F1}", median);
}
else //odd
{
int mid = (x / 2) <= 0 ? 0 : (newArr.Length / 2);
double median = newArr[mid];
Console.WriteLine("{0:F1}", median);
}
}
}
I am actually quite surprised that this solution has not been presented yet, and I feel like it is the easiest solution.
Go to GitHub, find the version of the brewfile that matches the version of icu4c
that you need and get the raw version of the file (follow the links above and click View File
then Raw
).
Then just have brew reinstall from that url.
For example, version 62.1
:
brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/575eb4bbef683551e19f329f60456b13a558132f/Formula/icu4c.rb
For example, version 64.2
:
brew reinstall https://raw.githubusercontent.com/Homebrew/homebrew-core/a806a621ed3722fb580a58000fb274a2f2d86a6d/Formula/icu4c.rb
I had also the same problem. Please add this line in application tag in manifest. I hope it will also help you.
android:usesCleartextTraffic="true"
All of the examples here (with the exception of rockacola's) require that the user physically click on the window to define focus. This isn't ideal, so .hover()
is the better choice:
$(window).hover(function(event) {
if (event.fromElement) {
console.log("inactive");
} else {
console.log("active");
}
});
This'll tell you when the user has their mouse on the screen, though it still won't tell you if it's in the foreground with the user's mouse elsewhere.
my solution:
; (function ($) {
$.each([ "toggle", "show", "hide" ], function( i, name ) {
var cssFn = $.fn[ name ];
$.fn[ name ] = function( speed, easing, callback ) {
if(speed == null || typeof speed === "boolean"){
var ret=cssFn.apply( this, arguments )
$.fn.triggerVisibleEvent.apply(this,arguments)
return ret
}else{
var that=this
var new_callback=function(){
callback.call(this)
$.fn.triggerVisibleEvent.apply(that,arguments)
}
var ret=this.animate( genFx( name, true ), speed, easing, new_callback )
return ret
}
};
});
$.fn.triggerVisibleEvent=function(){
this.each(function(){
if($(this).is(':visible')){
$(this).trigger('visible')
$(this).find('[data-trigger-visible-event]').triggerVisibleEvent()
}
})
}
})(jQuery);
example usage:
if(!$info_center.is(':visible')){
$info_center.attr('data-trigger-visible-event','true').one('visible',processMoreLessButton)
}else{
processMoreLessButton()
}
function processMoreLessButton(){
//some logic
}
Assuming you have the following constructor
class MyClass {
public MyClass(Long l, String s, int i) {
}
}
You will need to show you intend to use this constructor like so:
Class classToLoad = MyClass.class;
Class[] cArg = new Class[3]; //Our constructor has 3 arguments
cArg[0] = Long.class; //First argument is of *object* type Long
cArg[1] = String.class; //Second argument is of *object* type String
cArg[2] = int.class; //Third argument is of *primitive* type int
Long l = new Long(88);
String s = "text";
int i = 5;
classToLoad.getDeclaredConstructor(cArg).newInstance(l, s, i);
Short answer: the trade off is recursion is faster and for loops take up less memory in almost all cases. However there are usually ways to change the for loop or recursion to make it run faster
If you have a Decimal or similar numeric type, you can use:
Math.Round(myNumber, 2)
EDIT: So, in your case, it would be:
Public Class Form1
Private Sub btncalc_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btncalc.Click
txtA.Text = Math.Round((Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)), 2)
txtB.Text = Math.Round((Val(txtA.Text) * 1000 / Val(txtG.Text)), 2)
End Sub
End Class
I would like to mention one case where you must use std::move() otherwise it will give an error. Case: If the return type of the function differs from the type of the local variable.
class Base { ... };
class Derived : public Base { ... };
...
std::unique_ptr<Base> Foo() {
std::unique_ptr<Derived> derived(new Derived());
return std::move(derived); //std::move() must
}

Trying to run cleanup while your files are open gave me problems. as soon as I closed my application (Visual studio) I ran clean up and it was successful
In case you don't want to get mad with spaces in arguments and want to use variables try this:
objshell.run "cscript ""99 Writelog.vbs"" /r:" & r & " /f:""" & wscript.scriptname & """ /c:""" & c & ""
where
r=123
c="Whatever comment you like"
The next link will bring you to a great tutorial, that helped me a lot!
I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}
Python 3.4 introduced the pathlib
module into the standard library, which provides an object oriented approach to handle filesystem paths. The is_dir()
and exists()
methods of a Path
object can be used to answer the question:
In [1]: from pathlib import Path
In [2]: p = Path('/usr')
In [3]: p.exists()
Out[3]: True
In [4]: p.is_dir()
Out[4]: True
Paths (and strings) can be joined together with the /
operator:
In [5]: q = p / 'bin' / 'vim'
In [6]: q
Out[6]: PosixPath('/usr/bin/vim')
In [7]: q.exists()
Out[7]: True
In [8]: q.is_dir()
Out[8]: False
Pathlib is also available on Python 2.7 via the pathlib2 module on PyPi.
Two solutions for this error:
1. add this permission in your androidManifest.xml of your Android project
<uses-permission android:name="android.permission.INTERNET"/>
2. Turn on the Internet Connection of your device first.
I'm sure this question should have a more general answer with some reusable code that works with cookies as key-value pairs.
This snippet is taken from MDN and probably is trustable. This is UTF-safe object for work with cookies:
var docCookies = {
getItem: function (sKey) {
return decodeURIComponent(document.cookie.replace(new RegExp("(?:(?:^|.*;)\\s*" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=\\s*([^;]*).*$)|^.*$"), "$1")) || null;
},
setItem: function (sKey, sValue, vEnd, sPath, sDomain, bSecure) {
if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/i.test(sKey)) { return false; }
var sExpires = "";
if (vEnd) {
switch (vEnd.constructor) {
case Number:
sExpires = vEnd === Infinity ? "; expires=Fri, 31 Dec 9999 23:59:59 GMT" : "; max-age=" + vEnd;
break;
case String:
sExpires = "; expires=" + vEnd;
break;
case Date:
sExpires = "; expires=" + vEnd.toUTCString();
break;
}
}
document.cookie = encodeURIComponent(sKey) + "=" + encodeURIComponent(sValue) + sExpires + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "") + (bSecure ? "; secure" : "");
return true;
},
removeItem: function (sKey, sPath, sDomain) {
if (!sKey || !this.hasItem(sKey)) { return false; }
document.cookie = encodeURIComponent(sKey) + "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + ( sDomain ? "; domain=" + sDomain : "") + ( sPath ? "; path=" + sPath : "");
return true;
},
hasItem: function (sKey) {
return (new RegExp("(?:^|;\\s*)" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=")).test(document.cookie);
},
keys: /* optional method: you can safely remove it! */ function () {
var aKeys = document.cookie.replace(/((?:^|\s*;)[^\=]+)(?=;|$)|^\s*|\s*(?:\=[^;]*)?(?:\1|$)/g, "").split(/\s*(?:\=[^;]*)?;\s*/);
for (var nIdx = 0; nIdx < aKeys.length; nIdx++) { aKeys[nIdx] = decodeURIComponent(aKeys[nIdx]); }
return aKeys;
}
};
Mozilla has some tests to prove this works in all cases.
There is an alternative snippet here:
If you have this while Fiddler is running -> in Fiddler, go to 'Rules' and disable 'Automatically Authenticate' and it should work again.
Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.
Having added a new view controller scene to your storyboard, you then have to:
Create a UIViewController
subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":
And then select a unique name for the new view controller subclass:
Specify this new subclass as the base class for the scene you just added to the storyboard.
Now hook up any IBOutlet
and IBAction
references for this new scene with the new view controller subclass.
You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of
function email() {
// Opens SS by its ID
var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");
// Get the name of this SS
var name = ss.getName(); // Not necessary
// Read cell 1,1 * Line below does't work *
// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet
var range = sheet.getRange(1,1);
var data = range.getValue();
}
The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.
If you have Bluetooth, Use twedge on windows and getblue app on android, they also have a few videos of it. It's made by TEC-IT. I've got it to work by setting the interface option to bluetooth server in TWedge and setting the output setting in getblue to Bluetooth client and selecting my computer from the Bluetooth devices list. Make sure your computer and phone is paired. Also to get the barcode as input set the action setting in TWedge to Keyboard Wedge. This will allow for you to first click the input text box on said form, then scan said product with your phone and wait a sec for the barcode number to be put into the text box. Using this method requires no php that doesn't already exist in your current form processing, just process the text box as usual and viola your phone scans bar codes, sends them to your pc via Bluetooth wirelessly, your computer inserts the barcode into whatever text field is selected in any application or website. Hope this helps.
You can use .equals
for columns or entire dataframes.
df['col1'].equals(df['col2'])
If they're equal, that statement will return True
, else False
.
I have tried to create an image to explain this in the most simple words
1) Authentication means "Are you who you say you are?"
2) Authorization means "Should you be able to do what you are trying to do?".
This is also described in the image below.
I have tried to explain it in the best terms possible, and created an image of the same.
Despite the danger of stating the obvious: With a unit test you want to test the correct behaviour of the object - and this is defined in terms of its public interface. You are not interested in how the object accomplishes this task - this is an implementation detail and not visible to the outside. This is one of the things why OO was invented: That implementation details are hidden. So there is no point in testing private members. You said you need 100% coverage. If there is a piece of code that cannot be tested by using the public interface of the object, then this piece of code is actually never called and hence not testable. Remove it.
Like reorder()
in Alex Brown's answer, we could also use forcats::fct_reorder()
. It will basically sort the factors specified in the 1st arg, according to the values in the 2nd arg after applying a specified function (default = median, which is what we use here as just have one value per factor level).
It is a shame that in the OP's question, the order required is also alphabetical as that is the default sort order when you create factors, so will hide what this function is actually doing. To make it more clear, I'll replace "Goalkeeper" with "Zoalkeeper".
library(tidyverse)
library(forcats)
theTable <- data.frame(
Name = c('James', 'Frank', 'Jean', 'Steve', 'John', 'Tim'),
Position = c('Zoalkeeper', 'Zoalkeeper', 'Defense',
'Defense', 'Defense', 'Striker'))
theTable %>%
count(Position) %>%
mutate(Position = fct_reorder(Position, n, .desc = TRUE)) %>%
ggplot(aes(x = Position, y = n)) + geom_bar(stat = 'identity')
Here is just a nice trick to get the current error_handler method =)
<?php
register_shutdown_function('__fatalHandler');
function __fatalHandler()
{
$error = error_get_last();
// Check if it's a core/fatal error. Otherwise, it's a normal shutdown
if($error !== NULL && $error['type'] === E_ERROR) {
// It is a bit hackish, but the set_exception_handler
// will return the old handler
function fakeHandler() { }
$handler = set_exception_handler('fakeHandler');
restore_exception_handler();
if($handler !== null) {
call_user_func(
$handler,
new ErrorException(
$error['message'],
$error['type'],
0,
$error['file'],
$error['line']));
}
exit;
}
}
?>
Also I want to note that if you call
<?php
ini_set('display_errors', false);
?>
PHP stops displaying the error. Otherwise, the error text will be send to the client prior to your error handler.
I used JMock early. I've tried Mockito at my last project and liked it. More concise, more cleaner. PowerMock covers all needs which are absent in Mockito, such as mocking a static code, mocking an instance creation, mocking final classes and methods. So I have all I need to perform my work.
This also can happen if the device you are trying to run on has some older version of the provisioning profile you are using that points to an old, expired or revoked certificate or a certificate without associated private key. Delete any invalid Provisioning Profiles under your device section in Xcode organizer.
The example below from Java Tips is rather straight forward. I have since switched to Groovy for operations dealing with the file system - much easier and elegant. But here is the Java Tips one I used in the past. It lacks the robust exception handling that is required to make it fool-proof.
public void copyDirectory(File sourceLocation , File targetLocation)
throws IOException {
if (sourceLocation.isDirectory()) {
if (!targetLocation.exists()) {
targetLocation.mkdir();
}
String[] children = sourceLocation.list();
for (int i=0; i<children.length; i++) {
copyDirectory(new File(sourceLocation, children[i]),
new File(targetLocation, children[i]));
}
} else {
InputStream in = new FileInputStream(sourceLocation);
OutputStream out = new FileOutputStream(targetLocation);
// Copy the bits from instream to outstream
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
}
Simply add it to your current code, then call (new Date()).getWeek()
<script>
Date.prototype.getWeek = function() {
var onejan = new Date(this.getFullYear(), 0, 1);
return Math.ceil((((this - onejan) / 86400000) + onejan.getDay() + 1) / 7);
}
var weekNumber = (new Date()).getWeek();
var dayNames = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
var now = new Date();
document.write(dayNames[now.getDay()] + " (" + weekNumber + ").");
</script>
I tried this in one of the codeacademy exercises (reversing chars in a string without using reversed nor :: -1)
def reverse(text):
chars= []
l = len(text)
last = l-1
for i in range (l):
chars.append(text[last])
last-=1
result= ""
for c in chars:
result += c
return result
print reverse('hola')
You can use forEach starting from Java 8:
List<String> nameList = new ArrayList<>(
Arrays.asList("USA", "USSR", "UK"));
nameList.forEach((v) -> System.out.println(v));
If you have an instance function (i.e. one that gets passed self) you can use self to get a reference to the class using self.__class__
For example in the code below tornado creates an instance to handle get requests, but we can get hold of the get_handler
class and use it to hold a riak client so we do not need to create one for every request.
import tornado.web
import riak
class get_handler(tornado.web.requestHandler):
riak_client = None
def post(self):
cls = self.__class__
if cls.riak_client is None:
cls.riak_client = riak.RiakClient(pb_port=8087, protocol='pbc')
# Additional code to send response to the request ...
This is caused by an incompatibility with the android support library that changed to version 28. I solved the problem by forcing the build to use a lower support library. //like build gradle
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:27.1.0'
}
}
My project built successfully immediately after I changed this. Hope this might help you too. I lost a day of development because of this!.
The procedure that worked for me (following these rather old instructions with a few updates):
git --version
or install it via:sudo yum install git
sudo yum install gcc-c++ make
sudo yum install openssl-devel
node
(which you can remove later):git clone https://github.com/nodejs/node.git
cd node
git checkout v6.1.0
- put your desired version after the v
./configure
make
sudo make install
node --version
or simply node
(exit node via process.exit()
or ^C
x 2 or ^C
+ exit
) npm --version
and update if necessary via sudo npm install -g npm
node
directory with rm -r node
Notes:
sudo yum install nodejs --enablerepo=epel-testing
returns the error: No package nodejs available.
sudo yum install nodejs --enablerepo=epel
(ie without -testing
) only gave very old versions.sudo npm uninstall npm -g
...since npm can uninstall itselfsudo yum erase nodejs
sudo rm -f /usr/local/bin/node
sudo yum rm nodejs
in the accepted answer won't work as rm
is not a valid yum command see yum --help
)git clone git://github.com/nodejs/node.git
rather than git clone https://github.com/nodejs/node.git
but you may get a various errors (see here)./node
dir from a previous install, remove it before using the git clone command (or there'll be a conflict):rm -r node
sudo npm...
command - like sudo: npm: command not found
and/or have permissions issues installing node packages without sudo, edit sudo nano /etc/sudoers
and add :/usr/local/bin
to the end of the line Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
so that it reads Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
Yes , deleteBy method is supported To use it you need to annotate method with @Transactional
You can also use generic types, in my case, taking into account everything said before you can do something like:
public class SomeTypeManager<T> {
public SomeTypeManager(T someGeneric) {
//That's how you can achieve all previously said, with generic types.
Annotation[] an = someGeneric.getClass().getAnnotations();
}
}
Remember, that this will not equival at 100% to SomeClass.class.get(...)();
But can do the trick...
Simply sitting on a delimiter
local str = 'one,two'
local regxEverythingExceptComma = '([^,]+)'
for x in string.gmatch(str, regxEverythingExceptComma) do
print(x)
end
PHPMailer has the ability to automatically embed images from your HTML email. You have to give full path in the file system, when writing your HTML:
<img src="/var/www/host/images/photo.png" alt="my photo" />
It will automaticaly convert to:
<img src="cid:photo.png" alt="my photo" />
If the object is actually a Boolean
instance, then just cast it:
boolean di = (Boolean) someObject;
The explicit cast will do the conversion to Boolean
, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:
boolean di = ((Boolean) someObject).booleanValue();
If someObject
doesn't refer to a Boolean value though, what do you want the code to do?
This is a dual problem (as many in the world wide web world).
You need to evaluate if the browser supports html5 (I use Modernizr to do it). In this case if you have a normal form the browser will do the job for you, but if you need ajax/json (as many of everyday case) you need to perform manual verification anyway.
.. so, my suggestion is to use a regular expression to evaluate anytime before submit. The expression I use is the following:
var email = /^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$/;
This one is taken from http://www.regular-expressions.info/ . This is a hard world to understand and master, so I suggest you to read this page carefully.
Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity
).
Make sure you refer to the property as fileName
in the Criteria query, not filename
.
Specifically, Hibernate will call the getter method of the filename
property when executing that Criteria query, so it will look for a method called getFilename()
. But the property is called FileName
and the getter getFileName()
.
So, change the projection like so:
criteria.setProjection(Projections.property("fileName"));
If your code is more of a data analysis routine (vs. visualization / GUI), try GNU Octave. It's free and many of its functions are compatible with MATLAB. (Not 100% but maybe 99.5%.)
If you just want to append data to the Url You can do so by using HttpUrlConnection since HttpClient is now deprecated. A better way would be to use a library like-

But using libraries such as volley or retrofit is much better option because Asynctask class and HttpurlConnection is slower compared to libraries. Also the library will fetch everything and is faster as well.
In 2020 Dec, the fix did finally worked for me was restarting my mac.
Use the below approach to identify dates are sort or not
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy");
boolean decendingOrder = true;
for(int index=0;index<date.size() - 1; index++) {
if(simpleDateFormat.parse(date.get(index)).getTime() < simpleDateFormat.parse(date.get(index+1)).getTime()) {
decendingOrder = false;
break;
}
}
if(decendingOrder) {
System.out.println("Date are in Decending Order");
}else {
System.out.println("Date not in Decending Order");
}
}
I am trying to explain by putting problem statement and solution to it. I hope it will help
Problem Statement:
Find all the published products, whose name like ABC Product or PQR Product, and price should be less than 15/-
Solution:
Below are the conditions that need to be taken care of
Below is the statement that applies above criterion to create query and fetch data.
$elements = $collection->find(
Array(
[price] => Array( [$lt] => 15 ),
[$or] => Array(
[0]=>Array(
[product_name]=>Array(
[$in]=>Array(
[0] => ABC Product,
[1]=> PQR Product
)
)
)
),
[state]=>Published
)
);
Based on the syntax I'm assuming that it is some language which is descendant of C. As per what I have seen, length
is used for simple collection items like arrays and in most cases it is a property.
size()
is a function and is used for dynamic collection objects. However for all the purposes of using, you wont find any differences in outcome using either of them. In most implementations, size simply returns length property.
This worked for me.
You need to run it twice once for globals followed by locals
for name in dir():
if not name.startswith('_'):
del globals()[name]
for name in dir():
if not name.startswith('_'):
del locals()[name]
for(int i = 0; i < getArray.size(); i++){
Object object = getArray.get(i);
// now do something with the Object
}
You need to check for the type:
The values can be any of these types: Boolean, JSONArray, JSONObject, Number, String, or the JSONObject.NULL object. [Source]
In your case, the elements will be of type JSONObject, so you need to cast to JSONObject and call JSONObject.names()
to retrieve the individual keys.

Make sure to indicate lineterinator='\n'

Here is my solution:
with open('csvfile', 'a') as csvfile:

for i in range(0, len(data)):
spamwriter.writerow(data[i])

Something that wasn't mentioned before!
Make sure your outlet was correctly connected to the scrollView! It should have a filled circle, but even if you have filled circle, scrollView may not been connected - so double check! Hover over the circle and see if the actual scrollview gets highlighted! (This was a case for me)
//Connect below well to the scrollView in the storyBoard
@property (weak, nonatomic) IBOutlet UIScrollView *scrollView;
In Python 2.x, just use the ord
and chr
functions:
>>> ord('c')
99
>>> ord('c') + 1
100
>>> chr(ord('c') + 1)
'd'
>>>
Python 3.x makes this more organized and interesting, due to its clear distinction between bytes and unicode. By default, a "string" is unicode, so the above works (ord
receives Unicode chars and chr
produces them).
But if you're interested in bytes (such as for processing some binary data stream), things are even simpler:
>>> bstr = bytes('abc', 'utf-8')
>>> bstr
b'abc'
>>> bstr[0]
97
>>> bytes([97, 98, 99])
b'abc'
>>> bytes([bstr[0] + 1, 98, 99])
b'bbc'

string str1, str2, str3;
cout << "These are the strings: " << endl;
cout << "str1: \"the dog jumped over the fence\"" << endl;
cout << "str2: \"the\"" << endl;
cout << "str3: \"that\"" << endl << endl;
From this, I see that you have not initialized str1, str2, or str3 to contain the values that you are printing. I might suggest doing so first:
string str1 = "the dog jumped over the fence",
str2 = "the",
str3 = "that";
cout << "These are the strings: " << endl;
cout << "str1: \"" << str1 << "\"" << endl;
cout << "str2: \"" << str2 << "\"" << endl;
cout << "str3: \"" << str3 << "\"" << endl << endl;

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000
or Access-Control-Allow-Origin: *
on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true
on the POST response as well.
Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept
to match the requested header.
In the for, you have an iteration, then for each element of that loop which probably is a scalar, has no index. When each element is an empty array, single variable, or scalar and not a list or array you cannot use indices.
From SourceTree, click on Tools->Options. Then on the "General" tab, make sure to check the box to allow SourceTree to modify your Git config files.
Then switch to the "Diff" tab. On the lower half, use the drop down to select the external program you want to use to do the diffs and merging. I've installed KDiff3 and like it well enough. When you're done, click OK.
Now when there is a merge, you can go under Actions->Resolve Conflicts->Launch External Merge Tool.

Since I don't have a .snao or .prefs file in .metadata.plugins\org.eclipse.core.resources folder (running on OS X), what did the trick for me was copy the .project folder to old.project, start Eclipse, and check
Windows -> Preferences -> General -> Startup and Shutdown -> Refresh workspace on startup
as proposed by matt b. After that, I closed Eclipse, renamed the folder old.projects back to .projects and after that everything worked fine again.
You can use this to get remaining charged in percentage.
private void batteryLevel() {
BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver() {

int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
int level = -1;
if (rawlevel >= 0 && scale > 0) {
level = (rawlevel * 100) / scale;
}
batterLevel.setText("Battery Level Remaining: " + level + "%");
}

To complete J.F. Sebastian's answer, if you have a list of lists with different lengths, check out this great post from ActiveState. In short:
The built-in function zip does a similar job, but truncates the result to the length of the shortest list, so some elements from the original data may be lost afterwards.
To handle list of lists with different lengths, use:
def transposed(lists):
if not lists: return []
return map(lambda *row: list(row), *lists)
def transposed2(lists, defval=0):
if not lists: return []
return map(lambda *row: [elem or defval for elem in row], *lists)
str.strip()
returns a string with leading+trailing whitespace removed, .lstrip
and .rstrip
for only leading and trailing respectively.
grades.append(lists[i].rstrip('\n').split(','))
Hmm, surprised I don't see this answer yet, suppose I'll throw my hat in the ring.
class Action {
const cancelable = 0;
const target = 1
const type = 2;
public $cancelable;
public $target;
public $type;
__construct( $opt = [] ){
$this->cancelable = isset($opt[cancelable]) ? $opt[cancelable] : true;
$this->target = isset($opt[target]) ? $opt[target] : NULL;
$this->type = isset($opt[type]) ? $opt[type] : 'action';
}
}
$myAction = new Action( [
Action::cancelable => false,
Action::type => 'spin',
.

]);
You can optionally separate the options into their own class, such as extending SplEnum.
abstract class ActionOpt extends SplEnum{
const cancelable = 0;
const target = 1
const type = 2;
}
Another simple trick:
SELECT CONVERT(char(2), cast('2015-01-01' as datetime), 101) -- month with 2 digits
SELECT CONVERT(char(6), cast('2015-01-01' as datetime), 112) -- year (yyyy) and month (mm)
Outputs:

Taking a hint (or several) from olibre's answer, I like a Bash function:
function isEmptyDir {
[ -d $1 -a -n "$( find $1 -prune -empty 2>/dev/null )" ]
}
Because while it creates one subshell, it's as close to an O(1) solution as I can imagine and giving it a name makes it readable. I can then write
if isEmptyDir somedir
then
echo somedir is an empty directory
else
echo somedir does not exist, is not a dir, is unreadable, or is not empty
fi
As for O(1) there are outlier cases: if a large directory has had all or all but the last entry deleted, "find" may have to read the whole thing to determine whether it's empty. I believe that expected performance is O(1) but worst-case is linear in the directory size. I have not measured this.
Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.
Linux Crontab Format
MIN HOUR DOM MON DOW CMD
Example::Scheduling a Job For a Specific Time
The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM.
Please note that the time field uses 24 hours format. So, for 8 AM use 8, and for 8 PM use 20.
30 08 10 06 * /home/yourname/full-backup
In your case, for 2.30PM
,
30 14 * * * YOURCMD

I ran into the same error message while using the ChargifyNET.dll to communicate with the Chargify API. Adding chargify.ProtocolType = SecurityProtocolType.Tls12;
to the configuration solved the problem for me.
Here is the complete code snippet:

chargify.apiKey = ConfigurationManager.AppSettings["Chargify.apiKey"];
chargify.Password = ConfigurationManager.AppSettings["Chargify.apiPassword"];

// Without this an error will be thrown.
chargify.ProtocolType = SecurityProtocolType.Tls12;
return chargify;

You can see it in action in this CodePen and you can also see a Javascript version here (no jQuery).
I was looking for the solution to show the label dynamically from database like this:
checkbox1 : Option 1 text from database
checkbox2 : Option 2 text from database
checkbox3 : Option 3 text from database
checkbox4 : Option 4 text from database
So none of the above solution worked for me so I used like this:
@Html.CheckBoxFor(m => m.Option1, new { @class = "options" })
<label for="Option1">@Model.Option1Text</label>
@Html.CheckBoxFor(m => m.Option2, new { @class = "options" })
<label for="Option2">@Mode2.Option1Text</label>
In this way when user will click on label, checkbox will be selected.
Might be it can help someone.
The spec says seconds:
http://tools.ietf.org/html/draft-ietf-oauth-v2-22#section-4.2.2
expires_in
OPTIONAL. The lifetime in seconds of the access token. For
example, the value "3600" denotes that the access token will
expire in one hour from the time the response was generated.
I agree with OP that it's careless for Google to not document this.
If you cannot ignore the property, try modifying the visibility of the field. In our case, we had old code still submitting entities with the relationship, so in my case, this was the fix:
@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private Trainee trainee;
Also you can use JavaScript to solve your problem
iterate(item, index) {
console.log(`${item} has index ${index}`);
//Do what you want...
}
readJsonList() {
jsonList.forEach(this.iterate);
//it could be any array list.
}

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.
This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".
Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
strXls, True, "temp!"
Here's the easy and clean way. I like to duplicate my array right in the fast enumeration call:
for (LineItem *item in [NSArray arrayWithArray:self.lineItems])
{
if ([item.toBeRemoved boolValue] == YES)
{
[self.lineItems removeObject:item];
}
}
This way you enumerate through a copy of the array being deleted from, both holding the same objects. An NSArray holds object pointers only so this is totally fine memory/performance wise.
I found a workaround by using @ActiveProfiles("test")
and adding an application-test.yml file to src/test/resources.
It ended up looking like this:
@SpringApplicationConfiguration(classes = Application.class, initializers = ConfigFileApplicationContextInitializer.class)
@ActiveProfiles("test")
public abstract class AbstractIntegrationTest extends AbstractTransactionalJUnit4SpringContextTests {
}
The file application-test.yml just contains the properties that I want to override from application.yml (which can be found in src/main/resources).
Have you tried (from a command line)
java -jar jbpm-installer-3.2.7.jar
or double clicking it with the mouse ?
Found this and this by googling.
Hope it helps

Try calling setWillNotDraw(false)
from surfaceCreated
:
public void surfaceCreated(SurfaceHolder holder) {

@Override
protected void onDraw(Canvas canvas) {
canvas.drawRect(area, rectanglePaint);
Log.w(this.getClass().getName(), "On Draw Called");

and calling invalidate
from onTouchEvent
:
public boolean onTouch(View v, MotionEvent event) {
invalidate();
return true;
}
This technique is working for me:
$('#myInputFieldId').bind('input',function(){
alert("Hello");
});
Note that according to this JQuery doc, "on" is recommended rather than bind in newer versions.

If you'd like to extend
the Link
component to utilise some of the logic in it's onClick()
handler, here's how:
import React from 'react';
import { Link } from "react-router-dom";
// Extend react-router-dom Link to include a function for validation.
class LinkExtra extends Link {
render() {
const linkMarkup = super.render();
const { validation, ...rest} = linkMarkup.props; // Filter out props for <a>.
const onclick = event => {
if (!this.props.validation || this.props.validation()) {
this.handleClick(event);
} else {
event.preventDefault();
console.log("Failed validation");
}
}
return(
<a {...rest} onClick={onclick} />
)
}
}
export default LinkExtra;
Usage
<LinkExtra to="/mypage" validation={() => false}>Next</LinkExtra>
You should use thenReturn
or doReturn
when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.
thenReturn(T value)
Sets a return value to be returned when the method is called.
@Test
public void test_return() throws Exception {
Dummy dummy = mock(Dummy.class);
int returnValue = 5;
// choose your preferred way
when(dummy.stringLength("dummy")).thenReturn(returnValue);
doReturn(returnValue).when(dummy).stringLength("dummy");
}
Answer
is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.
Use
doAnswer()
when you want to stub a void method with genericAnswer
.Answer specifies an action that is executed and a return value that is returned when you interact with the mock.
@Test
public void test_answer() throws Exception {
Dummy dummy = mock(Dummy.class);
Answer<Integer> answer = new Answer<Integer>() {
public Integer answer(InvocationOnMock invocation) throws Throwable {
String string = invocation.getArgumentAt(0, String.class);
return string.length() * 2;
}
};
// choose your preferred way
when(dummy.stringLength("dummy")).thenAnswer(answer);
doAnswer(answer).when(dummy).stringLength("dummy");
}
I asked my developers to create a JavaScript variable "isProcessing" that I can access (in the "ae" object) that they set when things start running and clear when things are done. I then run it in an accumulator that checks it every 100 ms until it gets five in a row for a total of 500 ms without any changes. If 30 seconds pass, I throw an exception because something should have happened by then. This is in C#.
public static void WaitForDocumentReady(this IWebDriver driver)
{
Console.WriteLine("Waiting for five instances of document.readyState returning 'complete' at 100ms intervals.");
IJavaScriptExecutor jse = (IJavaScriptExecutor)driver;
int i = 0; // Count of (document.readyState === complete) && (ae.isProcessing === false)
int j = 0; // Count of iterations in the while() loop.
int k = 0; // Count of times i was reset to 0.
bool readyState = false;
while (i < 5)
{
System.Threading.Thread.Sleep(100);
readyState = (bool)jse.ExecuteScript("return ((document.readyState === 'complete') && (ae.isProcessing === false))");
if (readyState) { i++; }
else
{
i = 0;
k++;
}
j++;
if (j > 300) { throw new TimeoutException("Timeout waiting for document.readyState to be complete."); }
}
j *= 100;
Console.WriteLine("Waited " + j.ToString() + " milliseconds. There were " + k + " resets.");
}
function getCookie(name) {
var pair = document.cookie.split('; ').find(x => x.startsWith(name+'='));
if (pair)
return pair.split('=')[1]
}
The above responses are the better, but just for completeness, when you are in a component you can access the history object inside the VueRouter with: this.$router.history. That means we can listen to changes with:
this.$router.listen((newLocation) =>{console.log(newLocation);})
I think this is mainly useful when used along with this.$router.currentRoute.path

This issue happens when you reference a .NET Standard project from a .NET 4.x project: none of the .NET Standard project's nuget package references are brought in as dependencies.
I resolved by add System.Runtime 4.3
and NETStandard.Library package and !!important!! I use refactor tool to look up the System.Runtime.dll version, It is 4.1.1.1
not 4.3
and then add an bindingRedirect in .config
<dependentAssembly>
<assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="4.1.1.1" />

DateTime.Today
as it implies is todays date and you need to get the Date a day before so you subtract one day using AddDays(-1)
;
There are sufficient options available in DateTime to get the formatting like ToShortDateString
depending on your culture and you have no need to concatenate them individually.
Also you can have a desirable format in the .ToString()
version of the DateTime
instance
In addition to @Emilia Apostolova answer to get the ground truth labels, from
generator = train_datagen.flow_from_directory("train", batch_size=batch_size)
just call
y_true_labels = generator.classes
you can simply make it transparent
{
width: 20px;
height: 20px;
overflow: hidden;
color:transparent;
}
Here's a quote from a recent blog post from Dare Obasanjo.
SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle.
However the most notable similarity is that just like most of us can’t really take advantage of the benefits of a manual transmission vehicle because the majority of our driving is sitting in traffic on the way to and from work, there is a similar harsh reality in that most sites aren’t at Google or Facebook’s scale and thus have no need for a Bigtable or Cassandra.
To which I can add only that switching from MySQL, where you have at least some experience, to CouchDB, where you have no experience, means you will have to deal with a whole new set of problems and learn different concepts and best practices. While by itself this is wonderful (I am playing at home with MongoDB and like it a lot), it will be a cost that you need to calculate when estimating the work for that project, and brings unknown risks while promising unknown benefits. It will be very hard to judge if you can do the project on time and with the quality you want/need to be successful, if it's based on a technology you don't know.
