$env:path="$env:Path;C:\Python27"
will only set it for the current session. Next time you open Powershell, you will have to do the same thing again.
The [Environment]::SetEnvironmentVariable()
is the right way, and it would have set your PATH environment variable permanently. You just have to start Powershell again to see the effect in this case.
You could try:
$(this).closest(".column").prev().find(".inputQty").val();
You can change the listen port as per your requirement. This task can be accomplished in two diffrent ways. By changing config.xml file By changing in admin console Change the listen port in config.xml as per your requirement and bounce the domain. Admin Console Login to AdminConsole->Server->Configuration->ListenPort (Change it) Note: It is a bad practice to edit config.xml and try to edit in admin console(It's a good practise as well)
String parentWindowHandler = driver.getWindowHandle(); // Store your parent window
String subWindowHandler = null;
Set<String> handles = driver.getWindowHandles(); // get all window handles
Iterator<String> iterator = handles.iterator();
subWindowHandler = iterator.next();
driver.switchTo().window(subWindowHandler); // switch to popup window
// Now you are in the popup window, perform necessary actions here
driver.switchTo().window(parentWindowHandler); // switch back to parent window
try using a text editing controller. at the begining,
final myController = TextEditingController();
@override
void dispose() {
// Clean up the controller when the widget is disposed.
myController.dispose();
super.dispose();
}
and in the on press event,
onPressed: () {
commentController.clear();}
this will dismiss the keybord.
To split the difference of opinion
I prefer:
xls.DisplayAlerts = False
wb.SaveAs fullFilePath, AccessMode:=xlExclusive, ConflictResolution:=xlLocalSessionChanges
xls.DisplayAlerts = True
To avoid error on null value you can use this code:
{{ game.gameDate ? game.gameDate|date('Y-m-d H:i:s') : '' }}
Suppose constructors were inherited... then because every class eventually derives from Object, every class would end up with a parameterless constructor. That's a bad idea. What exactly would you expect:
FileInputStream stream = new FileInputStream();
to do?
Now potentially there should be a way of easily creating the "pass-through" constructors which are fairly common, but I don't think it should be the default. The parameters needed to construct a subclass are often different from those required by the superclass.
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 10;
FixBitmap = BitmapFactory.decodeFile(ImagePath, options);
//FixBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.gv);
byteArrayOutputStream = new ByteArrayOutputStream();
FixBitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteArrayOutputStream); //compress to 50% of original image quality
byteArray = byteArrayOutputStream.toByteArray();
ConvertImage = Base64.encodeToString(byteArray, Base64.DEFAULT);
I had this problem just now and managed to figure out what it was. Was referencing a colour in my values that was causing problems. So defined it manually instead of using one from the dropdown suggestions.Then it worked!
I had a similar need to parse out a set of parameters stored within an IIS logs' csUriQuery field, which looked like this: id=3598308&user=AD\user¶meter=1&listing=No
needed in this format.
I ended up creating a User-defined function to accomplish a string between, with the following assumptions:
NULL
is returned, and Here's the code:
CREATE FUNCTION dbo.str_between(@col varchar(max), @start varchar(50), @end varchar(50))
RETURNS varchar(max)
WITH EXECUTE AS CALLER
AS
BEGIN
RETURN substring(@col, charindex(@start, @col) + len(@start),
isnull(nullif(charindex(@end, stuff(@col, 1, charindex(@start, @col)-1, '')),0),
len(stuff(@col, 1, charindex(@start, @col)-1, ''))+1) - len(@start)-1);
END;
GO
For the above question, the usage is as follows:
DECLARE @a VARCHAR(MAX) = 'All I knew was that the dog had been very bad and required harsh punishment immediately regardless of what anyone else thought.'
SELECT dbo.str_between(@a, 'the dog', 'immediately')
-- Yields' had been very bad and required harsh punishment '
It means that in table kontakty
you have a row referencing the row in osoby
you want to delete. You have do delete that row first or set a cascade delete on the relation between tables.
Powodzenia!
Just like @Dampes8N said:
$result = mysql_query($sql,$conecction);
$fp = fopen('file.csv', 'w');
while($row = mysql_fetch_assoc($result)){
fputcsv($fp, $row);
}
fclose($fp);
Hope this helps.

I believe those comments refer specifically to the browsers, i.e., clicking links and submitting forms, not XMLHttpRequest
. XMLHttpRequest
is just a custom client that you wrote in JavaScript that uses the browser as a runtime.
UPDATE: To clarify, I did not mean (though I did write) that you wrote XMLHttpRequest
; I meant that you wrote the code that uses XMLHttpRequest
. The browsers do not natively support XMLHttpRequest
. XMLHttpRequest
comes from the JavaScript runtime, which may be hosted by a browser, although it isn't required to be (see Rhino). That's why people say browsers don't support PUT
and DELETE
—because it's actually JavaScript that is supporting them.
With universal app I had iPad splash screen showing up in simulator but not on device. The iPad would instead show the Default.png splash for the iPhone. The Default-Landscape.png and Default-Portrait.png files existing, so wth? Resolution should be correct since I created the screen captures using Window | Organizer | Screenshots and used 'Save as Default Image' for the iPad, then just renamed it.
Turns out (from my one app anyways) the two iPad screen shots have to be moved to the Resources-iPad directory. Then it all works fine. Seems obvious now, but in case anyone else has lost sleep over this... -Larry
The difference between getHeight()
and getMeasuredHeight()
is that first method will return actual height of the View
, the second one will return summary height of View
's children. In ohter words, getHeight()
returns view height, getMeasuredHeight()
returns height which this view needs to show all it's elements
I know this is an old question, but I thought I'd present one more solution that could be used if you'd like to avoid using named function expressions. (Not saying you should or should not avoid them, just presenting another solution)
var fn = (function() {
var innerFn = function(counter) {
console.log(counter);
if(counter > 0) {
innerFn(counter-1);
}
};
return innerFn;
})();
console.log("running fn");
fn(3);
var copyFn = fn;
console.log("running copyFn");
copyFn(3);
fn = function() { console.log("done"); };
console.log("fn after reassignment");
fn(3);
console.log("copyFn after reassignment of fn");
copyFn(3);

"WORKSPACE" environment variable works for the latest version of Jenkins Pipeline. You can use this in your Jenkins file: "${env.WORKSPACE}"
Sample use below:
def files = findFiles glob: '**/reports/*.json'
for (def i=0; i<files.length; i++) {
jsonFilePath = "${files[i].path}"
jsonPath = "${env.WORKSPACE}" + "/" + jsonFilePath
echo jsonPath
hope that helps!!
Just add this one-line class in your CSS, and use the bootstrap label
component.
.label-as-badge {
border-radius: 1em;
}
Compare this label
and badge
side by side:
<span class="label label-default label-as-badge">hello</span>
<span class="badge">world</span>
They appear the same. But in the CSS, label
uses em
so it scales nicely, and it still has all the "-color" classes. So the label will scale to bigger font sizes better, and can be colored with label-success, label-warning, etc. Here are two examples:
<span class="label label-success label-as-badge">Yay! Rah!</span>
Or where things are bigger:
<div style="font-size: 36px"><!-- pretend an enclosing class has big font size -->
<span class="label label-success label-as-badge">Yay! Rah!</span>
</div>
11/16/2015: Looking at how we'll do this in Bootstrap 4
Looks like .badge
classes are completely gone. But there's a built-in .label-pill
class (here) that looks like what we want.
.label-pill {
padding-right: .6em;
padding-left: .6em;
border-radius: 10rem;
}
In use it looks like this:
<span class="label label-pill label-default">Default</span>
<span class="label label-pill label-primary">Primary</span>
<span class="label label-pill label-success">Success</span>
<span class="label label-pill label-info">Info</span>
<span class="label label-pill label-warning">Warning</span>
<span class="label label-pill label-danger">Danger</span>
11/04/2014: Here's an update on why cross-pollinating alert classes with .badge
is not so great. I think this picture sums it up:
Those alert classes were not designed to go with badges. It renders them with a "hint" of the intended colors, but in the end consistency is thrown out the window and readability is questionable. Those alert-hacked badges are not visually cohesive.
The .label-as-badge
solution is only extending the bootstrap design. We are keeping intact all the decision making made by the bootstrap designers, namely the consideration they gave for readability and cohesion across all the possible colors, as well as the color choices themselves. The .label-as-badge
class only adds rounded corners, and nothing else. There are no color definitions introduced. Thus, a single line of CSS.
Yep, it is easier to just hack away and drop in those .alert-xxxxx
classes -- you don't have to add any lines of CSS. Or you could care more about the little things and add one line.

I was getting this error on amazon.ca, meetup.com, and the Symantec homepage.
I went to the update page in the Chrome browser (it was at 53.*) and checked for an upgrade, and it showed there was no updates available. After asking around my office, it turns out the latest version was 55 but I was stuck on 53 for some reason.
After upgrading (had to manually download from the Chrome website) the issues were gone!
I would create a button and an invisible input like so:
<button id="button">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />
and add some jQuery to trigger it:
$('#button').on('click', function() {
$('#file-input').trigger('click');
});
Same idea, without jQuery (credits to @Pascale):
<button onclick="document.getElementById('file-input').click();">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />
Toggled Fullscreen Solution:
This solution may look like a workaround, but it actually accounts for whether your app is fullscreen (aka hiding the status bar) or not:
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point(); display.getSize(size);
int barheight = size.y - findViewById(R.id.rootView).getHeight();
This way, if your app is currently fullscreen, barheight
will equal 0.
Personally I had to use this to correct absolute TouchEvent coordinates to account for the status bar as so:
@Override
public boolean onTouch(View view,MotionEvent event) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point(); display.getSize(size);
int YCoord = (int)event.getRawY() - size.y + rootView.getHeight());
}
And that will get the absolute y-coordinate whether the app be fullscreen or not.
Enjoy
simple answer:
let str = 'this is string, length is >26';_x000D_
_x000D_
console.log([...str]);
_x000D_
Step 1
We need set format data in function date(): Function date() returns a string formatted according to the givenformat string using the given integer timestamp or the current time ifno timestamp is given. In other words, timestampis optional anddefaults to the value of time().
<?php
echo date("F j, Y");
?>
result: March 30, 2010
Step 2
For "yesterday" date use php function mktime(): Function mktime() returns the Unix timestamp corresponding to thearguments given. This timestamp is a long integer containing the numberof seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and thetime specified. Arguments may be left out in order from right to left; any argumentsthus omitted will be set to the current value according to the localdate and time.
<?php
echo mktime(0, 0, 0, date("m"), date("d")-1, date("Y"));
?>
result: 1269820800
Step 3
Now merge all and look at this:
<?php
$yesterday = date("Y-m-d", mktime(0, 0, 0, date("m") , date("d")-1,date("Y")));
echo $yesterday;
?>
result: March 29, 2010
Operating similarly, it is possible to receive time hour back.
<?php
$yesterday = date("H:i:s",mktime(date("H"), 0, 0, date("m"),date("d"), date("Y")));
echo $yesterday;
?>
result: 20:00:00
or 7 days ago:
<?php
$week = date("Y-m-d",mktime(0, 0, 0, date("m"), date("d")-7,date("Y")));
echo $week;
?>
result: 2010-03-23
We all agree that SAF is horribly designed and slow, but Google has been pushing us to it. Given that getExternalStorageDirectory()

How about .delay()
?
$("#test").animate({"top":"-=80px"},1500)
.delay(1000)
.animate({"opacity":"0"},500);
def aliasAllColumns(t: DataFrame, p: String = "", s: String = ""): DataFrame =
{
t.select( t.columns.map { c => t.col(c).as( p + c + s) } : _* )
}
In case is isn't obvious, this adds a prefix and a suffix to each of the current column names. This can be useful when you have two tables with one or more columns having the same name, and you wish to join them but still be able to disambiguate the columns in the resultant table. It sure would be nice if there were a similar way to do this in "normal" SQL.
It passes control to interrupt vector 0x80
See http://en.wikipedia.org/wiki/Interrupt_vector
On Linux, have a look at this: it was used to handle system_call
. Of course on another OS this could mean something totally different.
CGI essentially passes the request off to any interpreter that is configured with the web server - This could be Perl, Python, PHP, Ruby, C pretty much anything. Perl was the most common back in the day thats why you often see it in reference to CGI.
CGI is not dead. In fact most large hosting companies run PHP as CGI as opposed to mod_php because it offers user level config and some other things while it is slower than mod_php. Ruby and Python are also typically run as CGI. they key difference here is that a server module runs as part of the actual server software - where as with CGI its totally outside the server The server just uses the CGI module to determine how to pass and recieve data to the outside interpreter.
I had the same use case, You can change your method defination in the following way :
@RequestMapping(value = "/saveFruits", method = RequestMethod.POST,
consumes = "application/json")
@ResponseBody
public ResultObject saveFruits(@RequestBody Map<String,List<String>> fruits) {
..
}
The only problem is it accepts any key in place of "fruits" but You can easily get rid of a wrapper if it is not big functionality.

With the AND's (&&

Batch Construct.
Here's an example on how to achieve this:
<Grid DockPanel.Dock="Right"
HorizontalAlignment="Right">
<StackPanel Orientation="Horizontal"
HorizontalAlignment="Right"
VerticalAlignment="Center">
<Button x:Name="MinimizeButton"
KeyboardNavigation.IsTabStop="False"
Click="MinimizeWindow"

Template="{StaticResource MinimizeButtonControlTemplate}" />
<Button x:Name="MaximizeButton"
KeyboardNavigation.IsTabStop="False"
Click="MaximizeClick"
Style="{DynamicResource MaximizeButton}"
Template="{DynamicResource MaximizeButtonControlTemplate}" />
<Button x:Name="CloseButton"
KeyboardNavigation.IsTabStop="False"
Command="{Binding ApplicationCommands.Close}"
Style="{DynamicResource CloseButton}"
Template="{DynamicResource CloseButtonControlTemplate}"/>
</StackPanel>
</Grid>
</DockPanel>
Handle Click Events in the code-behind.
For MouseDown -
App.Current.MainWindow.DragMove();
For Minimize Button -
App.Current.MainWindow.WindowState = WindowState.Minimized;
For DoubleClick and MaximizeClick
if (App.Current.MainWindow.WindowState == WindowState.Maximized)
{
App.Current.MainWindow.WindowState = WindowState.Normal;
}
else if (App.Current.MainWindow.WindowState == WindowState.Normal)
{
App.Current.MainWindow.WindowState = WindowState.Maximized;
}
If you want to take a copy of a live database, do the Backup/Restore method.
[In SQLS2000, not sure about 2008:] Just keep in mind that if you are using SQL Server accounts in this database, as opposed to Windows accounts, if the master DB is different or out of sync on the development server, the user accounts will not translate when you do the restore. I've heard about an SP to remap them, but I can't remember which one it was.
You can simply implement your own compare function
[compareWith]="compareItems"
See as well the docu. So the complete code would look like:
<div>
<mat-select
[(value)]="selected2" [compareWith]="compareItems">
<mat-option
*ngFor="let option of options2"
value="{{ option.id }}">
{{ option.name }}
</mat-option>
</mat-select>
</div>
and in the Typescript file:
compareItems(i1, i2) {
return i1 && i2 && i1.id===i2.id;
}
$?
is a parameter like any other. You can save its value to use before ultimately calling exit
.
exit_status=$?
if [ $exit_status -eq 1 ]; then
echo "blah blah blah"
fi
exit $exit_status
You can use async/await
for this. I would explain more, but there's nothing really to it. It's just a regular for
loop but I added the await
keyword before the construction of your Promise
What I like about this is your Promise can resolve a normal value instead of having a side effect like your code (or other answers here) include. This gives you powers like in The Legend of Zelda: A Link to the Past where you can affect things in both the Light World and the Dark World – ie, you can easily work with data before/after the Promised data is available without having to resort to deeply nested functions, other unwieldy control structures, or stupid IIFEs.
// where DarkWorld is in the scary, unknown future
// where LightWorld is the world we saved from Ganondorf
LightWorld ... await DarkWorld
So here's what that will look like ...
const someProcedure = async n =>_x000D_
{_x000D_
for (let i = 0; i < n; i++) {_x000D_
const t = Math.random() * 1000_x000D_
const x = await new Promise(r => setTimeout(r, t, i))_x000D_
console.log (i, x)_x000D_
}_x000D_
return 'done'_x000D_
}_x000D_
_x000D_
someProcedure(10).then(x => console.log(x)) // => Promise_x000D_
// 0 0_x000D_
// 1 1_x000D_
// 2 2_x000D_
// 3 3_x000D_
// 4 4_x000D_
// 5 5_x000D_
// 6 6_x000D_
// 7 7_x000D_
// 8 8_x000D_
// 9 9_x000D_
// done
_x000D_
See how we don't have to deal with that bothersome .then
call within our procedure? And async
keyword will automatically ensure that a Promise
is returned, so we can chain a .then
call on the returned value. This sets us up for great success: run the sequence of n
Promises, then do something important – like display a success/error message.

Ok - thanks to all of you - let me wrap this up:
Other answers correctly talk about the Python ternary operator. I would like to complement by mentioning a scenario for which the ternary operator is often used but for which there is a better idiom. This is the scenario of using a default value.
Suppose we want to use option_value
with a default value if it is not set:
run_algorithm(option_value if option_value is not None else 10)
or, if option_value
is never set to a falsy value (0
, ""
, etc), simply
run_algorithm(option_value if option_value else 10)
However, in this case an ever better solution is simply to write
run_algorithm(option_value or 10)

For Unicode support:
public class HexadecimalEncoding
{
public static string ToHexString(string str)
{
var sb = new StringBuilder();
var bytes = Encoding.Unicode.GetBytes(str);
foreach (var t in bytes)
{
sb.Append(t.ToString("X2"));
}
return sb.ToString(); // returns: "48656C6C6F20776F726C64" for "Hello world"
}
public static string FromHexString(string hexString)
{
var bytes = new byte[hexString.Length / 2];
for (var i = 0; i < bytes.Length; i++)
{
bytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
}
return Encoding.Unicode.GetString(bytes); // returns: "Hello world" for "48656C6C6F20776F726C64"
}
}
Actually you need two div's for vertical centering. The div containing the content must have a width and height.
#container {_x000D_
position: absolute;_x000D_
top: 50%;_x000D_
margin-top: -200px;_x000D_
/* half of #content height*/_x000D_
left: 0;_x000D_
width: 100%;_x000D_
}_x000D_
_x000D_
#content {_x000D_
width: 624px;_x000D_
margin-left: auto;_x000D_
margin-right: auto;_x000D_
height: 395px;_x000D_
border: 1px solid #000000;_x000D_
}
_x000D_
<div id="container">_x000D_
<div id="content">_x000D_
<h1>Centered div</h1>_x000D_
</div>_x000D_
</div>
_x000D_
Here is the result
I know this is an old question, but is the first google result for "sort observablecollection" so thought it worth to leave my two cent.
The way I would go is to build a List<>
starting from the ObservableCollection<>
, sort it (through its Sort()
method, more on msdn) and when the List<>
has been sorted, reorder the ObservableCollection<>
with the Move()
method.
public static void Sort<T>(this ObservableCollection<T> collection, Comparison<T> comparison)
{
var sortableList = new List<T>(collection);
sortableList.Sort(comparison);
for (int i = 0; i < sortableList.Count; i++)
{
collection.Move(collection.IndexOf(sortableList[i]), i);
}
}
public void TestObservableCollectionSortExtension()
{
var observableCollection = new ObservableCollection<int>();
var maxValue = 10;
// Populate the list in reverse mode [maxValue, maxValue-1, ..., 1, 0]
for (int i = maxValue; i >= 0; i--)
{
observableCollection.Add(i);
}
// Assert the collection is in reverse mode
for (int i = maxValue; i >= 0; i--)
{
Assert.AreEqual(i, observableCollection[maxValue - i]);
}
// Sort the observable collection
observableCollection.Sort((a, b) => { return a.CompareTo(b); });
// Assert elements have been sorted
for (int i = 0; i < maxValue; i++)
{
Assert.AreEqual(i, observableCollection[i]);
}
}
This is just a proof of concept, showing how to sort an ObservableCollection<>
without breaking the bindings on items.The sort algorithm has room for improvements and validations (like index checking as pointed out here).
You can often get information from the header files. For example:
$ cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
$ find usr -name \*.h -exec fgrep -l EXC_I386_GPFLT {} \;
usr/include/mach/i386/exception.h
^C
$ more usr/include/mach/i386/exception.h
....
#define EXC_I386_GPFLT 13 /* general protection fault */
OK, so it's a general protection fault (as its name suggests anyway). Googling "i386 general protection fault" yields many hits, but this looks interesting:
Memory protection is also implemented using the segment descriptors. First, the processor checks whether a value loaded in a segment register references a valid descriptor. Then it checks that every linear address calculated actually lies within the segment. Also, the type of access (read, write, or execute) is checked against the information in the segment descriptor. Whenever one of these checks fails, exception (interrupt) 13 (hex 0D) is raised. This exception is called a General Protection Fault (GPF).
That 13
matches what we saw in the header files, so it looks like the same thing. However from the application programmer's point-of-view, it just means we're referencing memory we shouldn't be, and it's doesn't really matter how it's implemented on the hardware.
Instead of using isnull
use a case
, because of performance it is better the case.
case when campo is null then '' else campo end
In your issue you need to do this:
case when campo is null then '' else
case when len(campo) = 0 then '' else campo en
end
Code like this:
create table #tabla(
id int,
campo varchar(10)
)
insert into #tabla
values(1,null)
insert into #tabla
values(2,'')
insert into #tabla
values(3,null)
insert into #tabla
values(4,'dato4')
insert into #tabla
values(5,'dato5')
select id, case when campo is null then 'DATA NULL' else
case when len(campo) = 0 then 'DATA EMPTY' else campo end
end
from #tabla
drop table #tabla
You can do this way
a, b = map(int, input().split())
OR
a, b = input().split()
print(int(a))
OR
MyList = list(map(int, input().split()))
a = MyList[0]
b = MyList[1]
I hope to provide more background knowledge here.
First, constructor signature of the of method threading::Thread:
class threading.Thread(group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None)
args is the argument tuple for the target invocation. Defaults to ().
Second, A quirk in Python about tuple
:
Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses).
On the other hand, a string is a sequence of characters, like 'abc'[1] == 'b'
. So if send a string to args
, even in parentheses (still a sting), each character will be treated as a single parameter.
However, Python is so integrated and is not like JavaScript where extra arguments can be tolerated. Instead, it throws an TypeError
to complain.
you can use strbuilder.insert(0,i);
Just to add a note, since I can't comment without 50+ rep...
If you have FIPS enabled on the server, it doesn't allow you to create users. Because IIS v8 (and lower I would imagine) does not use FIPS encryption algorithms. It would be great if it supported it , because obviously a user account in windows is insecure compared to a virtual user mapped to an isolated folder. Too bad.
You may want to try window.focus() - but it may be annoying if the screen switches around
In VSCode for Mac (0.10.6) I opened "Preferences -> User Settings" and placed the following code in the settings.json file
"editor.referenceInfos": false
this was my solution:
i was looking for how to display the result not to calculate...
so. in this case. there is no column TOTAL in the database, but there is a total on the webpage...
<td><?php echo $row['amount1'] * $row['amount2'] ?></td>
also this was needed first...
<?php
$conn=mysql_connect('localhost','testbla','adminbla');
mysql_select_db("testa",$conn);
$query1 = "select * from info2";
$get=mysql_query($query1);
while($row=mysql_fetch_array($get)){
?>
Say, you have the following:
std::vector<myObject>::const_iterator first = vObj.begin();
Then the first object in the vector is: *first
. To get the address, use: &(*first)
.
However, in keeping with the STL design, I'd suggest return an iterator instead if you plan to pass it around later on to STL algorithms.
Because in C++, the final executable code does not carry any symbol information, it's more or less pure machine code.
Thus, you need a way to describe the interface of a piece of code, that is separate from the code itself. This description is in the header file.

I think using the first form is probably the way to go, since it's probably by far the most common loop structure in the known universe, and since I don't believe the reverse loop saves you any time in reality (still doing an increment/decrement and a comparison on each iteration).
Code that is recognizable and readable to others is definitely a good thing.
C++ gives you three ways to pass an object: by pointer, by reference, and by value. Java limits you with the latter one (the only exception is primitive types like int, boolean etc). If you want to use C++ not just like a weird toy, then you'd better get to know the difference between these three ways.
Java pretends that there is no such problem as 'who and when should destroy this?'. The answer is: The Garbage Collector, Great and Awful. Nevertheless, it can't provide 100% protection against memory leaks (yes, java can leak memory). Actually, GC gives you a false sense of safety. The bigger your SUV, the longer your way to the evacuator.
C++ leaves you face-to-face with object's lifecycle management. Well, there are means to deal with that (smart pointers family, QObject in Qt and so on), but none of them can be used in 'fire and forget' manner like GC: you should always keep in mind memory handling. Not only should you care about destroying an object, you also have to avoid destroying the same object more than once.
Not scared yet? Ok: cyclic references - handle them yourself, human. And remember: kill each object precisely once, we C++ runtimes don't like those who mess with corpses, leave dead ones alone.
So, back to your question.
When you pass your object around by value, not by pointer or by reference, you copy the object (the whole object, whether it's a couple of bytes or a huge database dump - you're smart enough to care to avoid latter, aren't you?) every time you do '='. And to access the object's members, you use '.' (dot).
When you pass your object by pointer, you copy just a few bytes (4 on 32-bit systems, 8 on 64-bit ones), namely - the address of this object. And to show this to everyone, you use this fancy '->' operator when you access the members. Or you can use the combination of '*' and '.'.
When you use references, then you get the pointer that pretends to be a value. It's a pointer, but you access the members through '.'.
And, to blow your mind one more time: when you declare several variables separated by commas, then (watch the hands):
Example:
struct MyStruct
{
int* someIntPointer, someInt; //here comes the surprise
MyStruct *somePointer;
MyStruct &someReference;
};
MyStruct s1; //we allocated an object on stack, not in heap
s1.someInt = 1; //someInt is of type 'int', not 'int*' - value/pointer modifier is individual
s1.someIntPointer = &s1.someInt;
*s1.someIntPointer = 2; //now s1.someInt has value '2'
s1.somePointer = &s1;
s1.someReference = s1; //note there is no '&' operator: reference tries to look like value
s1.somePointer->someInt = 3; //now s1.someInt has value '3'
*(s1.somePointer).someInt = 3; //same as above line
*s1.somePointer->someIntPointer = 4; //now s1.someInt has value '4'
s1.someReference.someInt = 5; //now s1.someInt has value '5'
//although someReference is not value, it's members are accessed through '.'
MyStruct s2 = s1; //'NO WAY' the compiler will say. Go define your '=' operator and come back.
//OK, assume we have '=' defined in MyStruct
s2.someInt = 0; //s2.someInt == 0, but s1.someInt is still 5 - it's two completely different objects, not the references to the same one

You need to use Integer.parseInt(String)

if(evt.getSource()==jTextField2){
int jml = Integer.parseInt(jTextField3.getText());
jTextField1.setText(numberToWord(jml));
}
}
Here is a function called ucfirst() (short for "upper case first letter"):
function ucfirst(str) {
var firstLetter = str.substr(0, 1);
return firstLetter.toUpperCase() + str.substr(1);
}
You can capitalise a string by calling ucfirst("some string") -- for example,
ucfirst("this is a test") --> "This is a test"
It works by splitting the string into two pieces. On the first line it pulls out firstLetter and then on the second line it capitalises firstLetter by calling firstLetter.toUpperCase() and joins it with the rest of the string, which is found by calling str.substr(1).
You might think this would fail for an empty string, and indeed in a language like C you would have to cater for this. However in JavaScript, when you take a substring of an empty string, you just get an empty string back.

<body onload=""> should override window.onload.
With <body onload="">, document.body.onload might be null, undefined or a function depending on the browser (although getAttribute("onload") should be somewhat consistent for getting the body of the anonymous function as a string). With window.onload, when you assign a function to it, window.onload will be a function consistently across browsers. If that matters to you, use window.onload.
window.onload is better for separating the JS from your content anyway. There's not much reason to use <body onload=""> anyway when you can use window.onload.
In Opera, the event target for window.onload and <body onload=""> (and even window.addEventListener("load", func, false)) will be the window instead of the document like in Safari and Firefox. But, 'this' will be the window across browsers.
What this means is that, when it matters, you should wrap the crud and make things consistent or use a library that does it for you.
Here is a macro I use to get the maximum value for signed integers, which is independent of the size of the signed integer type used, and for which gcc -Woverflow won't complain
#define SIGNED_MAX(x) (~(-1 << (sizeof(x) * 8 - 1)))
int a = SIGNED_MAX(a);
long b = SIGNED_MAX(b);
char c = SIGNED_MAX(c); /* if char is signed for this target */
short d = SIGNED_MAX(d);
long long e = SIGNED_MAX(e);
For the record, the spring.jpa.hibernate.ddl-auto
property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto
.
The values create
, create-drop
, validate
, and update
basically influence how the schema tool management will manipulate the database schema at startup.
For example, the update
operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.
The update
operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.
Typically in test case scenarios, you'll likely use create-drop
so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.
In development, it's often common to see developers use update
to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.
In production, it's often highly recommended you use none
or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.
Of course, "Fagner Antunes Dornelles" is correct in its answer. But it seems to me that it is worth checking the registry branch itself in addition, or be sure of the part that is exactly there.
For example ("dirty hack"), i need to establish trust in the RMS infrastructure, otherwise when i open Word or Excel documents, i will be prompted for "Active Directory Rights Management Services". Here's how i can add remote trust to me servers in the enterprise infrastructure.

ymin, ymax = axes.get_ylim()
If you are using the plt

altogether:
def myplotfunction(title, values, errors, plot_file_name):
# plot errorbars
indices = range(0, len(values))
fig = plt.figure()
plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')
plt.ylim([-0.5, len(values) - 0.5])
plt.xlabel('My x-axis title')
plt.ylabel('My y-axis title')
# title
plt.title(title)
# save as file
plt.savefig(plot_file_name)
# close figure
plt.close(fig)
in the spirit of sharing... this is a method I use frequently to run shell scripts. you can add a script to your product bundle (in the copy phase of the build) and then have the script be read and run at runtime. note: this code looks for the script in the privateFrameworks sub-path. warning: this could be a security risk for deployed products, but for our in-house development it is an easy way to customize simple things (like which host to rsync to...) without re-compiling the application, but just editing the shell script in the bundle.

If you are using NSTask to run a command-line utility via bash, then you need to include this magic line to keep NSLog working:

In context:
NSPipe *pipe;

[task setStandardOutput: pipe];
//The magic line that keeps your log where it belongs
[task setStandardInput:[NSPipe pipe]];

Like this:
Dim rng as Range
Set rng = ActiveCell.Resize(numRows, numCols)
then read the contents of that range to an array:
Dim arr As Variant
arr = rng.Value
'arr is now a two-dimensional array of size (numRows, numCols)
or, select the range (I don't think that's what you really want, but you ask for this in the question).
rng.Select
I'd give all the responses here a try first. But I wanted to just throw in what I do, just in case these do not work for you.
I've tried to solve the same problem you're having before, and in the end, what I decided on doing is to have only one JRE installed on my system at a given time. I do have about 10 different JDKs (1.3 through 1.6, and from various vendors - Sun, Oracle, IBM), since I do need it for development, but only one standalone JRE.
This has worked for me on my Windows 2000 + IE 6 computer at home, as well as my Windows XP + Multiple IE computer at work.

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:
<Router>
<Route path="/" component={App}>
<Route path="page1" component={Page1} />
<Route path="page2" component={Page2} />
</Route>
<Route path="/login" component={Login} />
</Router>
And the other components would look something like this:
var NavBar = React.createClass({
render() {
return (
<div>
<ul>
<a onClick={() => history.push('page1') }>Page 1</a>
<a onClick={() => history.push('page2') }>Page 2</a>
</ul>
</div>
)
}
});
var App = React.createClass({
render() {
return (
<div>
<NavBar />
<div>Other Content</div>
{this.props.children}
</div>
)
}
});
For elementwise multiplication of matrix
objects, you can use numpy.multiply
:
import numpy as np
a = np.array([[1,2],[3,4]])
b = np.array([[5,6],[7,8]])
np.multiply(a,b)
Result
array([[ 5, 12],
[21, 32]])
However, you should really use array
instead of matrix
. matrix
objects have all sorts of horrible incompatibilities with regular ndarrays. With ndarrays, you can just use *
for elementwise multiplication:
a * b
If you're on Python 3.5+, you don't even lose the ability to perform matrix multiplication with an operator, because @
does matrix multiplication now:
a @ b # matrix multiplication
Are you rebooting the device into the bootloader and entering fastboot USB on the bootloader menu?
Try
adb reboot bootloader
then look for on screen instructions to enter fastboot mode.
Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
Console applications will exit when the main function has finished running. A "return" will achieve this.
static void Main(string[] args)
{
while (true)
{
Console.WriteLine("I'm running!");
return; //This will exit the console application's running thread
}
}
If you're returning an error code you can do it this way, which is accessible from functions outside of the initial thread:
System.Environment.Exit(-1);
The answer about threading is good, but you need to be a bit more specific about what you want to do.
If you have two functions that both use a lot of CPU, threading (in CPython) will probably get you nowhere. Then you might want to have a look at the multiprocessing module or possibly you might want to use jython/IronPython.
If CPU-bound performance is the reason, you could even implement things in (non-threaded) C and get a much bigger speedup than doing two parallel things in python.
Without more information, it isn't easy to come up with a good answer.
One of my favorites tricks with bash is the "tar pipe". When you have a monstrous quantity of files to copy from one directory to another, doing "cp * /an/other/dir" doesn't work if the number of files is too high and explode the bash globber, so, the tar pipe :
(cd /path/to/source/dir/ ; tar cf - * ) | (cd /path/to/destination/ ; tar xf - )
...and if you have netcat, you can even do the "netcat tar pipe" through the network !!
You should not map score to player. You should map player (or his name) to score:
Map<Player, Integer> player2score = new HashMap<Player, Integer>();
Then add players to map: int score = .... Player player = new Player(); player.setName("John"); // etc. player2score.put(player, score);
In this case the task is trivial:
int score = player2score.get(player);
The iFrame attribute does not support percent in HTML5. It only supports pixels. http://www.w3schools.com/tags/att_iframe_height.asp
var isImgLoaded = function(imgSelector){
return $(imgSelector).prop("complete") && $(imgSelector).prop("naturalWidth") !== 0;
}
// Or As a Plugin
$.fn.extend({
isLoaded: function(){
return this.prop("complete") && this.prop("naturalWidth") !== 0;
}
})
// $(".myImage").isLoaded()
Using just awk you could do (I also shortened some of your piping):
strings -a libAddressDoctor5.so | awk '/EngineVersion/ { if(NR==2) { gsub("\"",""); print $2 } }'
I can't verify it for you because I don't know your exact input, but the following works:
echo "Blah EngineVersion=\"123\"" | awk '/EngineVersion/ { gsub("\"",""); print $2 }'
See also this question on removing single quotes.
Remove your Gemfile.lock.
Move to bash if you are using zsh.
sudo bash
gem update --system
Now run command bundle to create a new Gemfile.lock file.
Move back to your zsh sudo exec zsh
now run your rake commands.
I suggest you to have a ~/.mongorc.js
file so you do not have to set the default size everytime.
# execute in your terminal
touch ~/.mongorc.js
echo 'DBQuery.shellBatchSize = 100;' > ~/.mongorc.js
# add one more line to always prettyprint the ouput
echo 'DBQuery.prototype._prettyShell = true; ' >> ~/.mongorc.js
To know more about what else you can do, I suggest you to look at this article: http://mo.github.io/2017/01/22/mongo-db-tips-and-tricks.html
This is a supplemental answer for those arriving here based on the question title (like I did) and don't need to deal with the security issues related to saving passwords.
User settings are generally saved locally in Android using SharedPreferences
with a key-value pair. You use the String
key to save or look up the associated value.
String key = "myInt";
int valueToSave = 10;
SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(key, valueToSave).commit();
Use apply()
instead of commit()
to save in the background rather than immediately.
String key = "myInt";
int defaultValue = 0;
SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
int savedValue = sharedPref.getInt(key, defaultValue);
The default value is used if the key isn't found.
Rather than using a local key String in multiple places like I did above, it would be better to use a constant in a single location. You could use something like this at the top of your settings activity:
final static String PREF_MY_INT_KEY = "myInt";
I used an int
in my example, but you can also use putString()
, putBoolean()
, getString()
, getBoolean()
, etc.
See the documentation for more details.
There are multiple ways to get SharedPreferences. See this answer for what to look out for.
For Python 3:
import urllib.request, urllib.error
url = 'http://www.google.com/asdfsf'
try:
conn = urllib.request.urlopen(url)
except urllib.error.HTTPError as e:
# Return code error (e.g. 404, 501, ...)
# ...
print('HTTPError: {}'.format(e.code))
except urllib.error.URLError as e:
# Not an HTTP-specific error (e.g. connection refused)
# ...
print('URLError: {}'.format(e.reason))
else:
# 200
# ...
print('good')
This is the best solution (IMO) as it requires no jQuery and no JSON decode:
Source: https://wordpress.stackexchange.com/a/179373 and: https://stackoverflow.com/a/1714899/196507
Summary:
//Replacement of jQuery.param
var serialize = function(obj, prefix) {
var str = [];
for(var p in obj) {
if (obj.hasOwnProperty(p)) {
var k = prefix ? prefix + "[" + p + "]" : p, v = obj[p];
str.push(typeof v == "object" ?
serialize(v, k) :
encodeURIComponent(k) + "=" + encodeURIComponent(v));
}
}
return str.join("&");
};
//Your AngularJS application:
var app = angular.module('foo', []);
app.config(function ($httpProvider) {
// send all requests payload as query string
$httpProvider.defaults.transformRequest = function(data){

return data;
}
return serialize(data);
};
// set all post requests content type
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
});
Example:
...
var data = { id: 'some_id', name : 'some_name' };
$http.post(my_php_url,data).success(function(data){
// It works!
}).error(function() {
// :(
});
PHP code:
<?php
$id = $_POST["id"];
?>
You are experiencing this issue for two reasons.
When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)
User.java
@Entity
@Table(name="user")
public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="iduser")
private Long idUser;
@Column(name="user_name")
private String userName;
@OneToOne()
@JoinColumn(name="idarea")
private Area area;
public Long getIdUser() {
return idUser;
}
public void setIdUser(Long idUser) {
this.idUser = idUser;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Area getArea() {
return area;
}
public void setArea(Area area) {
this.area = area;
}
}
Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:
@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")
While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.
Area.java
@Entity
@Table(name = "area")
public class Area {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="idarea")
private Long idArea;
@Column(name="area_name")
private String areaName;
@OneToOne(fetch=FetchType.LAZY, mappedBy="area")
private User user;
public Long getIdArea() {
return idArea;
}
public void setIdArea(Long idArea) {
this.idArea = idArea;
}
public String getAreaName() {
return areaName;
}
public void setAreaName(String areaName) {
this.areaName = areaName;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
The following works for me.
string strToday = DateTime.Today.ToString("MM/dd/yyyy");
I had the same problem and none of these solutions worked and I don't know why, they worked for me in the past for similar problems.
Anyway to solve the problem I've just manually rebuild the package using node-pre-gyp
cd node_modules/bcrypt
node-pre-gyp rebuild
And everything worked as expected.
Hope this helps

Ok, wasted a lot of time on this so here is a summary as of 19 March 2019
If you are specifically trying to use a Docker image with MySql 8+, and then use SequelPro to access your database(s) running on that docker container, you are out of luck.
See the sequelpro issue 2699
My setup is sequelpro 1.1.2 using docker desktop 2.0.3.0 (mac - mojave), and tried using mysql:latest (v8.0.15).
As others have reported, using mysql 5.7 works with nothing required:
docker run -p 3306:3306 --name mysql1 -e MYSQL_ROOT_PASSWORD=secret -d mysql:5.7
Of course, it is possible to use MySql 8+ on docker, and in that situation (if needed), other answers provided here for caching_sha2_password
type issues do work. But sequelpro is a NO GO with MySql 8+
Finally, I abandoned sequelpro (a trusted friend from back in 2013-2014) and instead installed DBeaver. Everything worked out of the box. For docker, I used:
docker run -p 3306:3306 --name mysql1 -e MYSQL_ROOT_PASSWORD=secret -d mysql:latest --default-authentication-plugin=mysql_native_password
You can quickly peek at the mysql databases using:
docker exec -it mysql1 bash
mysql -u root -p
show databases;
Ros the code i post also is for knowing how many services are running...
Imagine you want to know how many services are like Oracle* then you put Oracle instead of NameOfSercive... and you get the number of services like Oracle* running on the variable %CountLines% and if you want to do something if there are only 4 you can do something like this:
IF 4==%CountLines% GOTO FourServicesAreRunning
That is much more powerfull... and your code does not let you to know if desired service is running ... if there is another srecive starting with same name... imagine: -ServiceOne -ServiceOnePersonal
If you search for ServiceOne, but it is only running ServiceOnePersonal your code will tell ServiceOne is running...
My code can be easly changed, since it reads all lines of the file and read line by line it can also do whatever you want to each service... see this:
@ECHO OFF
REM Put here any code to be run before check for Services
SET TemporalFile=TemporalFile.TXT
NET START > %TemporalFile%
SET CountLines=0
FOR /F "delims=" %%X IN (%TemporalFile%) DO SET /A CountLines=1+CountLines
SETLOCAL EnableDelayedExpansion
SET CountLine=0
FOR /F "delims=" %%X IN (%TemporalFile%) DO @(
SET /A CountLine=1+CountLine
REM Do whatever you want to each line here, remember first and last are special not service names
IF 1==!CountLine! (
REM Do whatever you want with special first line, not a service.
) ELSE IF %CountLines%==!CountLine! (
REM Do whatever you want with special last line, not a service.
) ELSE (
REM Do whatever you want with rest lines, for each service.
REM For example echo its position number and name:
echo !CountLine! - %%X
REM Or filter by exact name (do not forget to not remove the three spaces at begining):
IF " NameOfService"=="%%X" (
REM Do whatever you want with Service filtered.
)
)
REM Do whatever more you want to all lines here, remember two first are special as last one
)
DEL -P %TemporalFile% 2>nul
SET TemporalFile=
REM Put here any code to be run after check for Services
Of course it only list running services, i do not know any way net can list not running services...
Hope this helps!!!

It seems the new version of msbuild does not ship with Microsoft.WebApplication.targets. To fix you need to update your csproj file as so:
1) Edit the web app csproj (right click). Find the section in the csproj towards the bottom concerning build tools. It should look like so.
<PropertyGroup>
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
</PropertyGroup>
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />
2) You need to add one VSToolsPath line below the VisualStudioVersion tag so it looks like so
<PropertyGroup>
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
<!--Add the below line to fix the project loading in VS 2017 -->
<VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
<!--End -->
</PropertyGroup>
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />

You can add this method to your Status enum:
public static String getStringValueFromInt(int i) {
for (Status status : Status.values()) {
if (status.getValue() == i) {
return status.toString();
}
}
// throw an IllegalArgumentException or return null
throw new IllegalArgumentException("the given number doesn't match any Status.");
}
public static void main(String[] args) {
System.out.println(Status.getStringValueFromInt(1)); // OUTPUT: START
}
I know this is old, BUT for anyone else looking:
Remove https:// from the hostname and add port 443 instead.
{
method: 'POST',
hostname: 'api.dropbox.com',
port: 443
}
In case this helps someone, if you're using Visual Studio Code, it expects the file to be in UTF-8 encoding. To generate the file, I ran pylint --generate-rcfile | out-file -encoding utf8 .pylintrc
in PowerShell.
try Integer.toString(integer value);
method as
ed = (EditText)findViewById(R.id.box);
int x = 10;
ed.setText(Integer.toString(x));
as Itsproinc said, the REN
command works!
but if your file path/name has spaces, use quotes " "
example:
ren C:\Users\&username%\Desktop\my file.txt not my file.txt
add " "
ren "C:\Users\&username%\Desktop\my file.txt" "not my file.txt"
hope it helps
You could use OHHTTPStubs and stub the network requests to specific URLs to fail.
You can get all checked checkboxes like this:
var boxes = $(":checkbox:checked");
And all non-checked like this:
var nboxes = $(":checkbox:not(:checked)");
You could merely cycle through either one of these collections, and store those names. If anything is absent, you know it either was or wasn't checked. In PHP, if you had an array of names which were checked, you could simply do an in_array()
request to know whether or not any particular box should be checked at a later date.
jQuery also has a serialize method that will maintain the state of your form controls. For instance, the example provided on jQuery's website follows:
single=Single2&multiple=Multiple&multiple=Multiple3&check=check2&radio=radio2
This will enable you to keep the information for which elements were checked as well.
Usually all users will have write access to /tmp. Place the file to /tmp and then login to putty , then you can sudo and copy the file.
In the answers here, up to now, we find two ways of changing the JRE locale setting:
Programatically, using Locale.setDefault() (which, in my case, was the solution, since I didn't want to require any action of the user):
Locale.setDefault(new Locale("pt", "BR"));
Via arguments to the JVM:
java -jar anApp.jar -Duser.language=pt-BR
But, just as reference, I want to note that, on Windows, there is one more way of changing the locale used by the JRE, as documented here: changing the system-wide language.
Note: You must be logged in with an account that has Administrative Privileges.
Click Start > Control Panel.
Windows 7 and Vista: Click Clock, Language and Region > Region and Language.
Windows XP: Double click the Regional and Language Options icon.
The Regional and Language Options dialog box appears.
Windows 7: Click the Administrative tab.
Windows XP and Vista: Click the Advanced tab.
(If there is no Advanced tab, then you are not logged in with administrative privileges.)
Under the Language for non-Unicode programs section, select the desired language from the drop down menu.
Click OK.
The system displays a dialog box asking whether to use existing files or to install from the operating system CD. Ensure that you have the CD ready.
Follow the guided instructions to install the files.
Restart the computer after the installation is complete.
Certainly on Linux the JRE also uses the system settings to determine which locale to use, but the instructions to set the system-wide language change from distro to distro.
Sorting by date doesn't require anything special. Just sort by the desired date field of the collection.
Updated for the 1.4.28 node.js native driver, you can sort ascending on datefield
using any of the following ways:
collection.find().sort({datefield: 1}).toArray(function(err, docs) {...});
collection.find().sort('datefield', 1).toArray(function(err, docs) {...});
collection.find().sort([['datefield', 1]]).toArray(function(err, docs) {...});
collection.find({}, {sort: {datefield: 1}}).toArray(function(err, docs) {...});
collection.find({}, {sort: [['datefield', 1]]}).toArray(function(err, docs) {...});
'asc'
or 'ascending'
can also be used in place of the 1
.
To sort descending, use 'desc'
, 'descending'
, or -1
in place of the 1
.
L
: long i = 12345678910L;
.BTW: it doesn't have to be an upper case L, but lower case is confused with 1
many times :).
If you look in the source code for $.fn.bind
you will find that it's just an rewrite function for on
:
function (types, data, fn) {
return this.on(types, null, data, fn);
}

DateTime
is not standard nullable type. If you want assign null to DateTime
type of variable, you have to use DateTime?
type which supports null value.
If you only want test your variable to be set (e.g. variable holds other than default value), you can use keyword "default" like in following code:
if (dateTimeVariable == default(DateTime))
{
//do work for dateTimeVariable == null situation
}
A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py
create hello.py
then write the following function as its content:
def helloworld():
print "hello"
Then you can import hello
:
>>> import hello
>>> hello.helloworld()
'hello'
>>>
To group many .py
files put them in a folder. Any folder with an __init__.py
is considered a module by python and you can call them a package
|-HelloModule
|_ __init__.py
|_ hellomodule.py
You can go about with the import statement on your module the usual way.
For more information, see 6.4. Packages.
Swift 4 example:
var filePath: String {
//manager lets you examine contents of a files and folders in your app.
let manager = FileManager.default
//returns an array of urls from our documentDirectory and we take the first
let url = manager.urls(for: .documentDirectory, in: .userDomainMask).first
//print("this is the url path in the document directory \(String(describing: url))")
//creates a new path component and creates a new file called "Data" where we store our data array
return(url!.appendingPathComponent("Data").path)
}
I put the check in my loadData function which I called in viewDidLoad.
override func viewDidLoad() {
super.viewDidLoad()
loadData()
}
Then I defined loadData below.
func loadData() {
let manager = FileManager.default
if manager.fileExists(atPath: filePath) {
print("The file exists!")
//Do what you need with the file.
ourData = NSKeyedUnarchiver.unarchiveObject(withFile: filePath) as! Array<DataObject>
} else {
print("The file DOES NOT exist! Mournful trumpets sound...")
}
}
I realize this is a pretty old question, but I had the same thing come up today and came up with the following solution:
doSomethingToRequestData().then(function(downloadedFile) {
// create a download anchor tag
var downloadLink = document.createElement('a');
downloadLink.target = '_blank';
downloadLink.download = 'name_to_give_saved_file.pdf';
// convert downloaded data to a Blob
var blob = new Blob([downloadedFile.data], { type: 'application/pdf' });
// create an object URL from the Blob
var URL = window.URL || window.webkitURL;
var downloadUrl = URL.createObjectURL(blob);
// set object URL as the anchor's href
downloadLink.href = downloadUrl;
// append the anchor to document body
document.body.appendChild(downloadLink);
// fire a click event on the anchor
downloadLink.click();
// cleanup: remove element and revoke object URL
document.body.removeChild(downloadLink);
URL.revokeObjectURL(downloadUrl);
});
If t
is a matrix, you need to use the element-wise multiplication or exponentiation. Note the dot.
x = exp( -t.^2 )
or
x = exp( -t.*t )

You can reference any image via its URL. No matter where it is, as long as it's accesible you can use it as the src
. Example:
Relative location:
<img src="images/image.png">
The image is sought relative to the document's location. If your document is at http://example.com/site/document.html
, then your images
folder should be on the same directory where your document.html
file is.
Absolute location:
<img src="/site/images/image.png">
<img src="http://example.com/site/images/image.png">
or
<img src="http://another-example.com/images/image.png">
In this case, your image will be sought from the document site's root, so, if your document.html
is at http://example.com/site/document.html
, the root would be at http://example.com/
(or it's respective directory on the server's filesystem, commonly www/
). The first two examples are the same, since both point to the same host, Think of the first /
as an alias for your server's root. In the second case, the image is located in another host, so you'd have to specify the complete URL of the image.
Regarding /
, .
and ..
:
The /
symbol will always return the root of a filesystem or site.
The single point ./
points to the same directory where you are.
And the double point ../
will point to the upper directory, or the one that contains the actual working directory.
So you can build relative routes using them.
Examples given the route http://example.com/dir/one/two/three/
and your calling document being inside three/
:
"./pictures/image.png"
or just
"pictures/image.png"
Will try to find a directory named pictures
inside http://example.com/dir/one/two/three/
.
"../pictures/image.png"
Will try to find a directory named pictures
inside http://example.com/dir/one/two/
.
"/pictures/image.png"
Will try to find a directory named pictures
directly at /
or example.com
(which are the same), on the same level as directory
.
In AAA style using the explicitly typed initializer idiom:
#include <chrono>
#include <iostream>
int main(){
auto start = std::chrono::high_resolution_clock::now();
// Code to time here...
auto end = std::chrono::high_resolution_clock::now();
auto dur = end - start;
auto i_millis = std::chrono::duration_cast<std::chrono::milliseconds>(dur);
auto f_secs = std::chrono::duration_cast<std::chrono::duration<float>>(dur);
std::cout << i_millis.count() << '\n';
std::cout << f_secs.count() << '\n';
}
Try using join on a str conversion of your ints:
print(' '.join(str(x) for x in array))
For python 3.7
For the sake of anyone also using visual studio from a windows environment:
I realized that I could see my module installed when i ran pip install
py pip install [moduleName]
py pip list
However debugging in visual studio was getting "module not found". Oddly, i was successfully running import [moduleName]
when i ran the interpreter in powershell.
Reason:
visual studio was using the wrong interpreter at:
C:\Users\[username]\AppData\Local\Programs\Python\Python37\
What I REALLY wanted was visual studio to use the virtualenv that i setup for my project. To do this, right click Python Environments in "solution explorer", select Add Virtual Environment..., and then select the folder where you created your virtual environment. Then, under project settings, under the General tab, select your virtual environment in the dropdown.
Now visual studio should be using the same interpreter and everything should play nice!
Content Hugging and Content Compression Resistence Priorities work for elements which can calculate their size intrinsically depending upon the contents which are coming in.
From Apple docs:
@echo off
for /f "usebackq tokens=*" %%x in (`chdir`) do set var=%%x
echo The currenct directory is: %var%
But, of course, gmaran23's answer is the much easier one.
Here is a solution that guarantees entire file will be read, that requires no libraries and is efficient:
byte[] fullyReadFileToBytes(File f) throws IOException {
int size = (int) f.length();
byte bytes[] = new byte[size];
byte tmpBuff[] = new byte[size];
FileInputStream fis= new FileInputStream(f);;
try {
int read = fis.read(bytes, 0, size);
if (read < size) {
int remain = size - read;
while (remain > 0) {
read = fis.read(tmpBuff, 0, remain);
System.arraycopy(tmpBuff, 0, bytes, size - remain, read);
remain -= read;
}
}
} catch (IOException e){
throw e;
} finally {
fis.close();
}
return bytes;
}
NOTE: it assumes file size is less than MAX_INT bytes, you can add handling for that if you want.
TL;DR: python -m pip install -U pip
, then try again.
I was already using a venv
(virtualenv) in PyCharm.
Creating it I clicked inherit global site packages
checkbox, to allow packages installed via an installer to work.
Now inside my venv
there was no pip
installed, so it would use the inherited global pip
.
Here is how the error went:
(venv) D:\path\to\my\project> pip install certifi # or any other package
Would fail with
PermissionError: [WinError 5] Access denied: 'c:\\program files\\python36\\Lib\\site-packages\\certifi'
Notice how that is the path of the system python, not the venv
one.
However we want it to execute in the right environment.
Here some more digging:
(venv) D:\path\to\my\project> which pip
/c/Program Files/Python36/Scripts/pip
(venv) D:\path\to\my\project> which python
/d/path/to/my/project/venv/Scripts/python
So python is using the correct path, but pip is not? Let's install pip here in the correct one as well:
(venv) D:\path\to\my\project> python -m pip install -U pip
... does stuff ...
Successfully installed pip
Now that's better. Running the original failing command again now works, as it is using the correct pip.
(venv) D:\path\to\my\project> pip install certifi # or any other package
... install noise ...
Successfully installed certifi-2019.9.11 chardet-3.0.4 idna-2.8 requests-2.22.0 urllib3-1.25.7
If the target directory is empty, use find, filter with only directories, filter by name, execute rmdir:
find . -type d -name a -exec rmdir {} \;
If you want to recursively delete its contents, replace -exec rmdir {} \;
with -delete
or -prune -exec rm -rf {} \;
. Other answers include details about these versions, credit them too.
Checking Count() before the WHERE clause solved my problem. It is cheaper than ToList()
if (authUserList != null && _list.Count() > 0)
_list = _list.Where(l => authUserList.Contains(l.CreateUserId));
You could alternatively overwrite the 'yourElement.addEventListener()' method and use the '.apply()' method to execute the listener like normal, but intercepting the function in the process. Like:
<script type="text/javascript">
var args = [];
var orginalAddEvent = yourElement.addEventListener;
yourElement.addEventListener = function() {
//console.log(arguments);
args[args.length] = arguments[0];
args[args.length] = arguments[1];
orginalAddEvent.apply(this, arguments);
};
function removeListeners() {
for(var n=0;n<args.length;n+=2) {
yourElement.removeEventListener(args[n], args[n+1]);
}
}
removeListeners();
</script>
This script must be run on page load or it might not intercept all event listeners.
Make sure to remove the 'removeListeners()' call before using.
Try this;
var data = "";
data = "<option value = Some value> Some Option </option>";
options = [];
options.push(data);
select = document.getElementById("drop_down_id");
select.innerHTML = optionsHTML.join('\n');
Hashes can not be decrypted check this out.
If you want to encrypt-decrypt, use a two way encryption function of your database like - AES_ENCRYPT (in MySQL).
But I'll suggest CRYPT_BLOWFISH algorithm for storing password. Read this- http://php.net/manual/en/function.crypt.php and http://us2.php.net/manual/en/function.password-hash.php
For Blowfish by crypt()
function -
crypt('String', '$2a$07$twentytwocharactersalt$');
password_hash
will be introduced in PHP 5.5.
$options = [
'cost' => 7,
'salt' => 'BCryptRequires22Chrcts',
];
password_hash("rasmuslerdorf", PASSWORD_BCRYPT, $options);
Once you have stored the password, you can then check if the user has entered correct password by hashing it again and comparing it with the stored value.
In the question above the right answer would be to use Mock
, or to be more precise create_autospec
(because it will add spec to the mock methods of the class you are mocking), the defined spec
on the mock will be helpful in case of an attempt to call method of the class which doesn't exists ( regardless signature), please see some
from unittest import TestCase
from unittest.mock import Mock, create_autospec, patch
class MyClass:
@staticmethod
def method(foo, bar):
print(foo)
def something(some_class: MyClass):
arg = 1
# Would fail becuase of wrong parameters passed to methd.
return some_class.method(arg)
def second(some_class: MyClass):
arg = 1
return some_class.unexisted_method(arg)
class TestSomethingTestCase(TestCase):
def test_something_with_autospec(self):
mock = create_autospec(MyClass)
mock.method.return_value = True
# Fails because of signature misuse.
result = something(mock)
self.assertTrue(result)
self.assertTrue(mock.method.called)
def test_something(self):
mock = Mock() # Note that Mock(spec=MyClass) will also pass, because signatures of mock don't have spec.
mock.method.return_value = True
result = something(mock)
self.assertTrue(result)
self.assertTrue(mock.method.called)
def test_second_with_patch_autospec(self):
with patch(f'{__name__}.MyClass', autospec=True) as mock:
# Fails because of signature misuse.
result = second(mock)
self.assertTrue(result)
self.assertTrue(mock.unexisted_method.called)
class TestSecondTestCase(TestCase):
def test_second_with_autospec(self):
mock = Mock(spec=MyClass)
# Fails because of signature misuse.
result = second(mock)
self.assertTrue(result)
self.assertTrue(mock.unexisted_method.called)
def test_second_with_patch_autospec(self):
with patch(f'{__name__}.MyClass', autospec=True) as mock:
# Fails because of signature misuse.
result = second(mock)
self.assertTrue(result)
self.assertTrue(mock.unexisted_method.called)
def test_second(self):
mock = Mock()
mock.unexisted_method.return_value = True
result = second(mock)
self.assertTrue(result)
self.assertTrue(mock.unexisted_method.called)
The test cases with defined spec used fail because methods called from something
and second
functions aren't complaint with MyClass, which means - they catch bugs, whereas default Mock
will display.
As a side note there is one more option: use patch.object to mock just the class method which is called with.
The good use cases for patch would be the case when the class is used as inner part of function:
def something():
arg = 1
return MyClass.method(arg)
Then you will want to use patch as a decorator to mock the MyClass.
struct
and typedef
are two very different things.
The struct
keyword is used to define, or to refer to, a structure type. For example, this:
struct foo {
int n;
};
creates a new type called struct foo
. The name foo
is a tag; it's meaningful only when it's immediately preceded by the struct
keyword, because tags and other identifiers are in distinct name spaces. (This is similar to, but much more restricted than, the C++ concept of namespace
s.)
A typedef
, in spite of the name, does not define a new type; it merely creates a new name for an existing type. For example, given:
typedef int my_int;
my_int
is a new name for int
; my_int
and int
are exactly the same type. Similarly, given the struct
definition above, you can write:
typedef struct foo foo;
The type already has a name, struct foo
. The typedef
declaration gives the same type a new name, foo
.
The syntax allows you to combine a struct
and typedef
into a single declaration:
typedef struct bar {
int n;
} bar;
This is a common idiom. Now you can refer to this structure type either as struct bar
or just as bar
.
Note that the typedef name doesn't become visible until the end of the declaration. If the structure contains a pointer to itself, you have use the struct
version to refer to it:
typedef struct node {
int data;
struct node *next; /* can't use just "node *next" here */
} node;
Some programmers will use distinct identifiers for the struct tag and for the typedef name. In my opinion, there's no good reason for that; using the same name is perfectly legal and makes it clearer that they're the same type. If you must use different identifiers, at least use a consistent convention:
typedef struct node_s {
/* ... */
} node;
(Personally, I prefer to omit the typedef
and refer to the type as struct bar
. The typedef
save a little typing, but it hides the fact that it's a structure type. If you want the type to be opaque, this can be a good thing. If client code is going to be referring to the member n
by name, then it's not opaque; it's visibly a structure, and in my opinion it makes sense to refer to it as a structure. But plenty of smart programmers disagree with me on this point. Be prepared to read and understand code written either way.)
(C++ has different rules. Given a declaration of struct blah
, you can refer to the type as just blah
, even without a typedef. Using a typedef might make your C code a little more C++-like -- if you think that's a good thing.)
This is the format of /etc/crontab:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# | | | | |
# * * * * * user-name command to be executed
I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.
To run something every minute:
* * * * * username /var/www/html/a.php
To run something at midnight of every day:
0 0 * * * username /var/www/html/reset.php
You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:
chmod +x file.php
Start your php file with a shebang so that your shell knows which interpreter to use:
#!/usr/bin/php
<?php
// your code here
From SQL Server point of view:
Clustering will give you an active - passive configuration. Meaning in a 2 node cluster, one of them will be the active (serving) and the other one will be passive (waiting to take over when the active node fails). It's a high availability from hardware point of view.
You can have an active-active cluster, but it will require multiple instances of SQL Server running on each node. (i.e. Instance 1 on Node A failing over to Instance 2 on Node B, and instance 1 on Node B failing over to instance 2 on Node A).
Load balancing (at least from SQL Server point of view) does not exists (at least in the same sense of web server load balancing). You can't balance load that way. However, you can split your application to run on some database on server 1 and also run on some database on server 2, etc. This is the primary mean of "load balancing" in SQL world.
I'm not sure whether you think about:
select * from friend f
where not exists (
select 1 from likes l where f.id1 = l.id and f.id2 = l.id2
)
it works only if id1 is related with id1 and id2 with id2 not both.
Take a look at your code :
getUsers(): Observable<User[]> {
return Observable.create(observer => {
this.http.get('http://users.org').map(response => response.json();
})
}
and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)
getHeroes(): Promise<Hero[]> {
return this.http.get(this.heroesUrl)
.toPromise()
.then(response => response.json().data as Hero[])
.catch(this.handleError);
}
The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:
return Observable.create(observer => {
this.http.get('http://users.org').map(response => response.json()
Try to follow the guide in link that I provided. You should be just fine when you study it carefully.
---EDIT----
First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!
Try to do it like this:
getUsers(): void {
this.userService.getUsers()
.then(users => {
this.users = users
console.log('this.users=' + this.users);
});
}
See where the console.log(...) is!
Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.
Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.
You are missing default density value of 160.
2 px = 3 dip if dpi == 80(ldpi), 320x240 screen
1 px = 1 dip if dpi == 160(mdpi), 480x320 screen
3 px = 2 dip if dpi == 240(hdpi), 840x480 screen
In other words, if you design you layout with width equal to 160dip in portrait mode, it will be half of the screen on all ldpi/mdpi/hdpi devices(except tablets, I think)
I agree it is generally preferable to use an Array
for this.
However, this can also be accomplished in JavaScript by simply adding properties to the current scope (the global scope, if top-level code; the function scope, if within a function) by simply using this
– which always refers to the current scope.
for (var i = 0; i < coords.length; ++i) {
this["marker"+i] = "some stuff";
}
You can later retrieve the stored values (if you are within the same scope as when they were set):
var foo = this.marker0;
console.log(foo); // "some stuff"
This slightly odd feature of JavaScript is rarely used (with good reason), but in certain situations it can be useful.
There could be 3 solution from this posting and other stackoverflow article.
Solution 1
var lastScrollTop = 0;
$(window).on('scroll', function() {
st = $(this).scrollTop();
if(st < lastScrollTop) {
console.log('up 1');
}
else {
console.log('down 1');
}
lastScrollTop = st;
});
Solution 2
$('body').on('DOMMouseScroll', function(e){
if(e.originalEvent.detail < 0) {
console.log('up 2');
}
else {
console.log('down 2');
}
});
Solution 3
$('body').on('mousewheel', function(e){
if(e.originalEvent.wheelDelta > 0) {
console.log('up 3');
}
else {
console.log('down 3');
}
});
I couldn't tested it on Safari
chrome 42 (Win 7)
Firefox 37 (Win 7)
IE 11 (Win 8)
IE 10 (Win 7)
IE 9 (Win 7)
IE 8 (Win 7)
I checked that side effect from IE 11 and IE 8 is come from
if else
statement. So, I replaced it withif else if
statement as following.
From the multi browser test, I decided to use Solution 3 for common browsers and Solution 1 for firefox and IE 11.
I referred this answer to detect IE 11.
// Detect IE version
var iev=0;
var ieold = (/MSIE (\d+\.\d+);/.test(navigator.userAgent));
var trident = !!navigator.userAgent.match(/Trident\/7.0/);
var rv=navigator.userAgent.indexOf("rv:11.0");
if (ieold) iev=new Number(RegExp.$1);
if (navigator.appVersion.indexOf("MSIE 10") != -1) iev=10;
if (trident&&rv!=-1) iev=11;
// Firefox or IE 11
if(typeof InstallTrigger !== 'undefined' || iev == 11) {
var lastScrollTop = 0;
$(window).on('scroll', function() {
st = $(this).scrollTop();
if(st < lastScrollTop) {
console.log('Up');
}
else if(st > lastScrollTop) {
console.log('Down');
}
lastScrollTop = st;
});
}
// Other browsers
else {
$('body').on('mousewheel', function(e){
if(e.originalEvent.wheelDelta > 0) {
console.log('Up');
}
else if(e.originalEvent.wheelDelta < 0) {
console.log('Down');
}
});
}
EDIT:
The gcc guys really improved the diagnosis experience in gcc (ah competition). They created a wiki page to showcase it here. gcc 4.8 now has quite good diagnostics as well (gcc 4.9x added color support). Clang is still in the lead, but the gap is closing.
Original:
For students, I would unconditionally recommend Clang.
The performance in terms of generated code between gcc and Clang is now unclear (though I think that gcc 4.7 still has the lead, I haven't seen conclusive benchmarks yet), but for students to learn it does not really matter anyway.
On the other hand, Clang's extremely clear diagnostics are definitely easier for beginners to interpret.
Consider this simple snippet:
#include <string>
#include <iostream>
struct Student {
std::string surname;
std::string givenname;
}
std::ostream& operator<<(std::ostream& out, Student const& s) {
return out << "{" << s.surname << ", " << s.givenname << "}";
}
int main() {
Student me = { "Doe", "John" };
std::cout << me << "\n";
}
You'll notice right away that the semi-colon is missing after the definition of the Student
class, right :) ?
Well, gcc notices it too, after a fashion:
prog.cpp:9: error: expected initializer before ‘&’ token
prog.cpp: In function ‘int main()’:

I purposefully choose an example which triggers an unclear error message (coming from an ambiguity in the grammar) rather than the typical "Oh my god Clang read my mind" examples. Still, we notice that Clang avoids the flood of errors. No need to scare students away.
As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....
The ?
and the OR
needs to be seperated by a space character. Do it wherever needed in the query string.
Try this:
if(myString != "-1")
The opperand is !=
and not =!
You can also use Equals
if(!myString.Equals("-1"))
Note the !
before myString
Let me throw out some example code that I got from http://www3.ntu.edu.sg/home/ehchua/programming/java/DateTimeCalendar.html Then you can play around with different options until you understand it.
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateTest {
public static void main(String[] args) {
Date now = new Date();
//This is just Date's toString method and doesn't involve SimpleDateFormat
System.out.println("toString(): " + now); // dow mon dd hh:mm:ss zzz yyyy
//Shows "Mon Oct 08 08:17:06 EDT 2012"
SimpleDateFormat dateFormatter = new SimpleDateFormat("E, y-M-d 'at' h:m:s a z");
System.out.println("Format 1: " + dateFormatter.format(now));
// Shows "Mon, 2012-10-8 at 8:17:6 AM EDT"
dateFormatter = new SimpleDateFormat("E yyyy.MM.dd 'at' hh:mm:ss a zzz");
System.out.println("Format 2: " + dateFormatter.format(now));
// Shows "Mon 2012.10.08 at 08:17:06 AM EDT"
dateFormatter = new SimpleDateFormat("EEEE, MMMM d, yyyy");
System.out.println("Format 3: " + dateFormatter.format(now));
// Shows "Monday, October 8, 2012"
// SimpleDateFormat can be used to control the date/time display format:
// E (day of week): 3E or fewer (in text xxx), >3E (in full text)
// M (month): M (in number), MM (in number with leading zero)
// 3M: (in text xxx), >3M: (in full text full)
// h (hour): h, hh (with leading zero)
// m (minute)
// s (second)
// a (AM/PM)
// H (hour in 0 to 23)
// z (time zone)
// (there may be more listed under the API - I didn't check)
}
}
Good luck!
Use a bit of RegEx:
Regex.Match(Date.Now.ToString(), @"^.*?(?= )");
Produces a date in the format: dd/mm/yyyy
As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2)
as a simple alternative. Here's a more advanced mtext() example:
set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
yaxt="n", ylab="",
xlab="Regular boring x",
pch=16,
col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)
You may need to adjust the line=
option to get the optimal positioning of the text but apart from that it's really easy to use.
The other answers here work for something like Math, which is a static object. But they don't work for an instance of an object, such as a date. I found the following to work:
function getMethods(o) {
return Object.getOwnPropertyNames(Object.getPrototypeOf(o))
.filter(m => 'function' === typeof o[m])
}
//example: getMethods(new Date()): [ 'getFullYear', 'setMonth', ... ]
https://jsfiddle.net/3xrsead0/
This won't work for something like the original question (Math), so pick your solution based on your needs. I'm posting this here because Google sent me to this question but I was wanting to know how to do this for instances of objects.
I think while loop is alternate for the "goto_Statement". Because after 3.6 goto loop is not working anymore. I also write an example of the while loop.
str1 = "stop"
while str1 == "back":
var1 = int(input(" Enter Ist Number: "))
var2 = int(input(" Enter 2nd Number: "))
var3 = print(""" What is your next operation
For Addition Press And Enter : 'A'
For Muliplt Press And Enter : 'M'
For Division Press And Enter : 'D'
For Subtaction Press And Enter : 'S' """)
var4 = str(input("For operation press any number : "))
if(var1 == 45) and (var2 == 3):
print("555")
elif(var1 == 56) and (var2 == 9):
print("77")
elif(var1 == 56) and (var2 == 6):
print("4")
else:
if(var4 == "A" or "a"):
print(var1 + var2)
if(var4 == "M" or "m"):
print(var1 * var2)
if(var4 == "D" or "d"):
print(var1 / var2)
if(var4 == "S" or "s"):
print(var1 - var2)
print("if you want to continue then type 'stop'")
str1 = input()
print("Strt again")
I had the same problem.
It was caused by a corrupted file. If you added some new Drawable before getting this error, check them to see if they are correctly display in Android Studio Viewer.
Apache Camel is a lightweight integration framework that implements all Enterprise Integration patterns. You can easily integrate different applications using the required patterns. You can use Java, Spring XML, Scala or Groovy.
Apache Camel runs on the Java Virtual Machine (JVM). ... The core functionality of Apache Camel is its routing engine. It allocates messages based on the related routes. A route contains flow and integration logic. It is implemented using EIPs and a specific DSL.
The best way is to add the directory to the load path and then require
the basename of each file. This is because you want to avoid accidentally requiring the same file twice -- often not the intended behavior. Whether a file will be loaded or not is dependent on whether require
has seen the path passed to it before. For example, this simple irb session shows that you can mistakenly require and load the same file twice.
$ irb
irb(main):001:0> require 'test'
=> true
irb(main):002:0> require './test'
=> true
irb(main):003:0> require './test.rb'
=> false
irb(main):004:0> require 'test'
=> false
Note that the first two lines return true
meaning the same file was loaded both times. When paths are used, even if the paths point to the same location, require
doesn't know that the file was already required.
Here instead, we add a directory to the load path and then require the basename of each *.rb file within.
dir = "/path/to/directory"
$LOAD_PATH.unshift(dir)
Dir[File.join(dir, "*.rb")].each {|file| require File.basename(file) }
If you don't care about the file being required more than once, or your intention is just to load the contents of the file, perhaps load
should be used instead of require
. Use load in this case, because it better expresses what you're trying to accomplish. For example:
Dir["/path/to/directory/*.rb"].each {|file| load file }
This is the simplest thing you can do and it doesn't require any additional libraries. It will clear the screen and return >>>
to the top left corner.
print("\033[H\033[J")
Split the string in to string array and write using above method (I assume your text contains \n to get new line)
String[] test = test.split("\n");
and the inside a loop
bufferedWriter.write(test[i]);
bufferedWriter.newline();
As per the docs select, the following piece of code worked for me.
<div ng-controller="ExampleController">
<form name="myForm">
<label for="mySelect">Make a choice:</label>
<select name="mySelect" id="mySelect"
ng-options="option.name for option in data.availableOptions track by option.id"
ng-model="data.selectedOption"></select>
</form>
<hr>
<tt>option = {{data.selectedOption}}</tt><br/>
</div>
You might want to try the contains
selector:
if ($("#field > div.field-item:contains('someText')").length) {
$("#somediv").addClass("thisClass");
}
Also, as other mentioned, you must use == or === rather than =.
On Mac OSX, manually delete these 2 directories under your pathToPython/site-packages/ will work:
for example, to remove pyasn1, which is a distutils installed project:
To find out where is your site-packages:
python -m site
If you have password for your dB then
mysql -u <username> -p <DBName> < yourfile.sql
Simply put: 1) make sure all items are comparable 2) sort the array 2) iterate over the array and find duplicates
If you can catch this in time and you don't have the ability to ROLLBACK
or use the transaction log, you can take a backup immediately and use a tool like Redgate's SQL Data Compare to generate a script to "restore" the affected data. This worked like a charm for me. :)

This indents the entire file!
And below are some of the simple and elegant commands used to indent lines quickly in Vim or gVim.
To indent the all the lines below the current line
=G
To indent the current line
==
To indent n
lines below the current line
n==
For example, to indent 4 lines below the current line
4==
To indent a block of code, go to one of the braces and use command

What worked for me was using the $setSubmitted
function, which first shows up in the angular docs in version 1.3.20.
In the click event where I wanted to trigger the validation, I did the following:
vm.triggerSubmit = function() {
vm.homeForm.$setSubmitted();
...
}
That was all it took for me. According to the docs it "Sets the form to its submitted state." It's mentioned here.
Can also use
@(time(nil)).stringValue);
for timestamp in seconds.
I ran into this problem on the Raspberry Pi. After trying everything but a reinstall, on a whim, I deleted /var/run/apache2/apache2.pid. I restarted Apache and everything worked. Not sure how to explain that.

Using AddDays(-1)
worked for me until I tried to cross months. When I tried to subtract 2 days from 2017-01-01 the result was 2016-00-30. It could not handle the month change correctly (though the year seemed to be fine).
I used date = Convert.ToDateTime(date).Subtract(TimeSpan.FromDays(2)).ToString("yyyy-mm-dd");
and have no issues.
What you want is a type of software called a "Disassembler".

The easiest way to freeze the UI would be to make the AJAX call synchronous.
Usually synchronous AJAX calls defeat the purpose of using AJAX because it freezes the UI, but if you want to prevent the user from interacting with the UI, then do it.
Server is trying to read data from the request, but its taking longer than the timeout value for the data to arrive from the client. Timeout here would typically be tomcat connector -> connectionTimeout attribute.
Correct.
Client has a read timeout set, and server is taking longer than that to respond.
No. That would cause a timeout at the client.
One of the threads i went through, said this can happen with high concurrency and if the keepalive is enabled.
That is obviously guesswork, and completely incorrect. It happens if and only if no data arrives within the timeout. Period. Load and keepalive and concurrency have nothing to do with it whatsoever.
It just means the client isn't sending. You don't need to worry about it. Browser clients come and go in all sorts of strange ways.
If your string is
foo="US/Central - 10:26 PM (CST)"
then
echo "${foo}" | cut -d ' ' -f3
will do the job.
Modify the show search method like this
showSearch(){
this.show = !this.show;
setTimeout(()=>{ // this will make the execution after the above boolean has changed
this.searchElement.nativeElement.focus();
},0);
}
another dirty way:
grep -A80 -B80 --color FIND_THIS IN_FILE
I did an
alias grepa='grep -A80 -B80 --color'
in bashrc.
Try the below code:
Sub opendfiles()
Dim myfile As Variant
Dim counter As Integer
Dim path As String
myfolder = "D:\temp\"
ChDir myfolder
myfile = Application.GetOpenFilename(, , , , True)
counter = 1
If IsNumeric(myfile) = True Then
MsgBox "No files selected"
End If
While counter <= UBound(myfile)
path = myfile(counter)
Workbooks.Open path
counter = counter + 1
Wend
End Sub

You need to start the SQL Server manually. Press
windows + R
type
sqlservermanager12.msc
right click ->Start
A simpler way would be to do:
ObjectA.Verify(

It.Is<Params>(p => p.Id == 7)
)
);
If using ES2016 you can use async
and await
and do something like:
(async () => {
const data = await fetch(url)
myFunc(data)
}())
If using ES2015 you can use Generators. If you don't like the syntax you can abstract it away using an async
utility function as explained here.
If using ES5 you'll probably want a library like Bluebird to give you more control.
Finally, if your runtime supports ES2015 already execution order may be preserved with parallelism using Fetch Injection.
You can try bellow code
<select onchange="myfunction($(this).val())" id="myId">
</select>

My first answer ever in the hope that it'll be usefull to someone : I now this is an old question but I encountered exactly the same error as the above question as I'm writing a TcpServer class and I was trying to use pthreads. I found this question and I understand now why it was happening. I ended up doing this:
#include <thread>
method to run threaded -> void* TcpServer::sockethandler(void* lp) {/*code here*/}
and I call it with a lambda -> std::thread( [=] { sockethandler((void*)csock); } ).detach();
that seems a clean approach to me.
I have created a small library of category methods, called Linq to ObjectiveC, that makes this sort of thing more easy. Using the sort method with a key selector, you can sort by birthDate
as follows:
NSArray* sortedByBirthDate = [input sort:^id(id person) {
return [person birthDate];
}]
