1.1: If you are using p12 and a provision file, but not using AppID to log in, do not Select Automatically manage signing.
Which means you don't need to set your team. Just select your provision file and the machine code signing identity in Build Settings, like this Build Settings. Make sure the parameters are set as well.
And then go back to General. You will see General set, and that's OK.
You can loop the array with a for loop and the object properties with for-in loops.
for (var i=0; i<result.length; i++)
for (var name in result[i]) {
console.log("Item name: "+name);
console.log("Source: "+result[i][name].sourceUuid);
console.log("Target: "+result[i][name].targetUuid);
}
You want to do this - set a function that will be executed to respond to the onclick event:
document.getElementById('buttonLED'+id).onclick = function(){ writeLED(1,1); } ;
The things you are doing don't work because:
The onclick event handler expects to have a function, here you are assigning a string
document.getElementById('buttonLED'+id).onclick = "writeLED(1,1)";
In this, you are assigning as the onclick event handler the result of executing the writeLED(1,1) function:
document.getElementById('buttonLED'+id).onclick = writeLED(1,1);
This error also happens if you're using a self-signed certificate with a keyUsage
missing the value keyCertSign
.
Also you can use DownloadFileAsync
method in WebClient
class. It downloads to a local file the resource with the specified URI
. Also this method does not block the calling thread.
Sample:
webClient.DownloadFileAsync(new Uri("http://www.example.com/file/test.jpg"), "test.jpg");

Solution posted by Denys S. in the question post:
I quite messed it up with c to c++ conversion (basically env
variable stuff), but I got it working with the following code for C++:
#include <string.h>
#include <stdio.h>
#include <jni.h>
jstring Java_the_package_MainActivity_getJniString( JNIEnv* env, jobject obj){
jstring jstr = (*env)->NewStringUTF(env, "This comes from jni.");
jclass clazz = (*env)->FindClass(env, "com/inceptix/android/t3d/MainActivity");
jmethodID messageMe = (*env)->GetMethodID(env, clazz, "messageMe", "(Ljava/lang/String;)Ljava/lang/String;");
jobject result = (*env)->CallObjectMethod(env, obj, messageMe, jstr);
const char* str = (*env)->GetStringUTFChars(env,(jstring) result, NULL); // should be released but what a heck, it's a tutorial :)
printf("%s\n", str);
return (*env)->NewStringUTF(env, str);
}
And next code for java methods:
public class MainActivity extends Activity {
private static String LIB_NAME = "thelib";
static {
System.loadLibrary(LIB_NAME);
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = (TextView) findViewById(R.id.textview);
tv.setText(this.getJniString());
}
// please, let me live even though I used this dark programming technique
public String messageMe(String text) {
System.out.println(text);
return text;
}
public native String getJniString();
}
Do ctrl+F5 to compile and run your project without debugging. Look at the output pane (defaults to "Show output from Build"). If it compiled successfully, the path to the .exe file should be there after {projectname}.vcxproj ->
To adjust the length of the samples:
set key samplen X
(default is 4)
To adjust the vertical spacing of the samples:
set key spacing X
(default is 1.25)
and (for completeness), to adjust the fontsize:
set key font "<face>,<size>"
(default depends on the terminal)
And of course, all these can be combined into one line:
set key samplen 2 spacing .5 font ",8"
Note that you can also change the position of the key using set key at <position>
or any one of the pre-defined positions (which I'll just defer to help key
at this point)
You can also load the context while defining the servlet itself (WebApplicationContext)
<servlet>
<servlet-name>admin</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/*.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>admin</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
rather than (ApplicationContext)
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
or can do both together.
Drawback of just using WebApplicationContext is that it will load context only for this particular Spring entry point (DispatcherServlet
) where as with above mentioned methods context will be loaded for multiple entry points (Eg. Webservice Servlet, REST servlet
etc)
Context loaded by ContextLoaderListener
will infact be a parent context to that loaded specifically for DisplacherServlet . So basically you can load all your business service, data access or repository beans in application context and separate out your controller, view resolver beans to WebApplicationContext.
From your comment:
this line
DateTime Date = reader.GetDateTime(0);
was throwing the exception
The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:
SELECT * from INFO
Replace it with a query that retrieves only the two columns you're interested in:
SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO
Then try reading the values again:
var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1); // equivalent to time(7) from your database
Or:
var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];

You can do it using streams map function like below, get result in new stream for further processing.
Stream<Fruit> newFruits = fruits.stream().map(fruit -> {fruit.name+="s"; return fruit;});
newFruits.forEach(fruit->{
System.out.println(fruit.name);
});
Dirty trick: You could as well use lambda expression to pass any code you want including the call with parameters.
this.Include(includes, () =>
{
_context.Cars.Include(<parameters>);
});
I always do this to download the packages:
pip install --download /path/to/download/to_packagename
OR
pip install --download=/path/to/packages/downloaded -r requirements.txt
And when I want to install all of those libraries I just downloaded, I do this:
pip install --no-index --find-links="/path/to/downloaded/dependencies" packagename
OR
pip install --no-index --find-links="/path/to/downloaded/packages" -r requirements.txt
Update
Also, to get all the packages installed on one system, you can export them all to requirement.txt
that will be used to intall them on another system, we do this:
pip freeze > requirement.txt
Then, the requirement.txt
can be used as above for download, or do this to install them from requirement.txt
:
pip install -r requirement.txt

SQLAlchemy is very, very powerful. However it is not thread safe make sure you keep that in mind when working with cherrypy in thread-pool mode.
If you're using AngularJS in your project, just inject $filter and use it like here:
$filter('date')(value, 'HH:mm')
You can also format the output in the template, more on filters here.
For file deletion, I wrote following simple batch file which deleted all .pdf's recursively:
del /s /q "\\ad1pfrtg001\AppDev\ResultLogs\*.pdf"
del /s /q "\\ad1pfrtg001\Project\AppData\*.pdf"
Even for the local directory we can use it as:
del /s /q "C:\Project\*.pdf"
The same can be applied for directory deletion where we just need to change del with rmdir.
Make sure you url encode all of the query params in your url.
In my case there was a space ' ' in my url, and I was making an API call using curl, and my api server was giving this error.
Means the following url
http://somedomain.com?key=some value with space
should be
http://somedomain.com/?key=some%20value%20with%20space
On a rather unrelated note: more performance hacks!
When traversing the sequence, we can only get 3 possible cases in the 2-neighborhood of the current element N
(shown first):
To leap past these 2 elements means to compute (N >> 1) + N + 1
, ((N << 1) + N + 1) >> 1
and N >> 2
, respectively.
Let`s prove that for both cases (1) and (2) it is possible to use the first formula, (N >> 1) + N + 1
.
Case (1) is obvious. Case (2) implies (N & 1) == 1
, so if we assume (without loss of generality) that N is 2-bit long and its bits are ba
from most- to least-significant, then a = 1
, and the following holds:
(N << 1) + N + 1: (N >> 1) + N + 1:
b10 b1
b1 b
+ 1 + 1
---- ---
bBb0 bBb
where B = !b
. Right-shifting the first result gives us exactly what we want.
Q.E.D.: (N & 1) == 1 ? (N >> 1) + N + 1 == ((N << 1) + N + 1) >> 1
.
As proven, we can traverse the sequence 2 elements at a time, using a single ternary operation. Another 2× time reduction.
The resulting algorithm looks like this:
uint64_t sequence(uint64_t size, uint64_t *path) {
uint64_t n, i, c, maxi = 0, maxc = 0;
for (n = i = (size - 1) | 1; i > 2; n = i -= 2) {
c = 2;
while ((n = ((n & 3)? (n >> 1) + n + 1 : (n >> 2))) > 2)
c += 2;
if (n == 2)
c++;
if (c > maxc) {
maxi = i;
maxc = c;
}
}
*path = maxc;
return maxi;
}
int main() {
uint64_t maxi, maxc;
maxi = sequence(1000000, &maxc);
printf("%llu, %llu\n", maxi, maxc);
return 0;
}
Here we compare n > 2
because the process may stop at 2 instead of 1 if the total length of the sequence is odd.
Let`s translate this into assembly!

I recommend 2 things. First is associative array.
$person = Array();
$person['name'] = "Joe";
$person['age'] = 22;
Second is classes.

Sometime some C# approach makes the life easier in Java world..:
class XLINK {
static final short PAYLOAD = 102, ACK = 103, PAYLOAD_AND_ACK = 104;
}
//Now is trivial to use it like a C# enum:
int rcv = XLINK.ACK;
You have two issues in your code.. First you need reference to capture the element on click. Try adding another parameter to your function to reference this. Also active class is for li element initially while you are tryin to add it to "a" element in the function. try this..
<div class="row" style="padding-left:21px;">
<ul class="nav nav-tabs" style="padding-left:40px;">
<li class="active filter"><a href="#month" onclick="Data('month',this)">This Month</a></li>
<li class="filter"><a href="#year" onclick="Data('year',this)">Year</a></li>
<li class="filter"><a href="#last60" onclick="Data('last60',this)">60 Days</a></li>
<li class="filter"><a href="#last90" onclick="Data('last90',this)">90 Days</a></li>
</ul>
</div>
<script>
function Data(string,element)
{
//1. get some data from server according to month year etc.,
//2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
$('.filter').removeClass('active');
$(element).parent().addClass('active') ;
}
</script>
For me, a hint to wrap the troubled element in another HTML tag helped. However I also needed to add a key to that HTML tag. For example:
// Didn't work
<div>
<TroubledComponent/>
</div>
// Worked
<div key='uniqueKey'>
<TroubledComponent/>
</div>
it's easier to check first if the channel has elements, that would ensure the channel is alive.
func isChanClosed(ch chan interface{}) bool {
if len(ch) == 0 {
select {
case _, ok := <-ch:
return !ok
}
}
return false
}
We can use title()
function with negative line
value to bring down the title.
See this example:
plot(1, 1)
title("Title", line = -2)
The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.
I've found the answer regarding how to do this myself. Inside the model code, just put:
For Rails <= 2:
include ActionController::UrlWriter
For Rails 3:
include Rails.application.routes.url_helpers
This magically makes thing_path(self)
return the URL for the current thing, or other_model_path(self.association_to_other_model)
return some other URL.
Here is the little hack to overcome all the struggles you have for video autoplay in a website:
Note: Some browsers don't let videos to autoplay unless the user interacts with the device.
So scripts to check whether video is playing is:
Object.defineProperty(HTMLMediaElement.prototype, 'playing', {
get: function () {
return !!(this.currentTime > 0 && !this.paused && !this.ended && this.readyState > 2);
}});
And then you can simply autoplay the video by attaching event listeners to the body:
$('body').on('click touchstart', function () {
const videoElement = document.getElementById('home_video');
if (videoElement.playing) {
// video is already playing so do nothing
}
else {
// video is not playing
// so play video now
videoElement.play();
}
});
Note: autoplay
attribute is very basic which needs to be added to the video tag already other than these scripts.
You can see the working example with code here at this link:

If order matters, you should keep a property on the "T" objects in your list that denotes sequence. In order to swap them, just swap the value of that property, and then use that in the .Sort(comparison with sequence property)
Python is strongly, dynamically typed.
As for your example
bob = 1
bob = "bob"
This works because the variable does not have a type; it can name any object. After bob=1
, you'll find that type(bob)
returns int
, but after bob="bob"
, it returns str
. (Note that type
is a regular function, so it evaluates its argument, then returns the type of the value.)
Contrast this with older dialects of C, which were weakly, statically typed, so that pointers and integers were pretty much interchangeable. (Modern ISO C requires conversions in many cases, but my compiler is still lenient about this by default.)
I must add that the strong vs. weak typing is more of a continuum than a boolean choice. C++ has stronger typing than C (more conversions required), but the type system can be subverted by using pointer casts.
The strength of the type system in a dynamic language such as Python is really determined by how its primitives and library functions respond to different types. E.g., +
is overloaded so that it works on two numbers or two strings, but not a string and an number. This is a design choice made when +
was implemented, but not really a necessity following from the language's semantics. In fact, when you overload +
on a custom type, you can make it implicitly convert anything to a number:
def to_number(x):
"""Try to convert function argument to float-type object."""
try:
return float(x)
except (TypeError, ValueError):
return 0
class Foo:
def __init__(self, number):
self.number = number
def __add__(self, other):
return self.number + to_number(other)
Instance of class Foo
can be added to other objects:
>>> a = Foo(42)
>>> a + "1"
43.0
>>> a + Foo
42
>>> a + 1
43.0
>>> a + None
42
Observe that even though strongly typed Python is completely fine with adding objects of type int
and float
and returns an object of type float
(e.g., int(42) + float(1)
returns 43.0
). On the other hand, due to the mismatch between types Haskell would complain if one tries the following (42 :: Integer) + (1 :: Float)
. This makes Haskell a strictly typed language, where types are entirely disjoint and only a controlled form of overloading is possible via type classes.
I had the same issue. My problem was that my header type wasn't set properly.
I just added this before my json echo
header('Content-type: application/json');
Why not just using

You demonstrate a fundamental misunderstanding.
You never created an instance of SimpleClass at all, because you didn't call it.
for count in xrange(4):
x = SimpleClass()
x.attr = count
simplelist.append(x)
Or, if you let the class take parameters, instead, you can use a list comprehension.
simplelist = [SimpleClass(count) for count in xrange(4)]
uint16_t
is unsigned 16-bit integer.
unsigned short int
is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX
is 65535
). In practice, it usually is 16-bit, but you can't take that as guaranteed.
Note:
uint16_t
.inttypes.h
and stdint.h
are both introduced in C99. If you are using C89, define your own type.uint16_t
may not be provided in certain implementation(See reference below), but unsigned short int
is always available.Reference: C11(ISO/IEC 9899:201x) §7.20 Integer types
For each type described herein that the implementation provides) shall declare that typedef name and define the associated macros. Conversely, for each type described herein that the implementation does not provide, shall not declare that typedef name nor shall it define the associated macros. An implementation shall provide those types described as ‘‘required’’, but need not provide any of the others (described as ‘optional’’).
There is HTML and URI encodings. &
is &
encoded in HTML while %26
is &
in URI encoding.
So before URI encoding your string you might want to HTML decode and then URI encode it :)
var div = document.createElement('div');
div.innerHTML = '&AndOtherHTMLEncodedStuff';
var htmlDecoded = div.firstChild.nodeValue;
var urlEncoded = encodeURIComponent(htmlDecoded);
result %26AndOtherHTMLEncodedStuff

.
This is how I limit the results in MS SQL Server 2012:
SELECT *
FROM table1
ORDER BY columnName
OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY
NOTE: OFFSET
can only be used with or in tandem to ORDER BY
.
To explain the code line OFFSET xx ROWS FETCH NEXT yy ROW ONLY
The xx
is the record/row number you want to start pulling from in the table, i.e: If there are 40 records in table 1, the code above will start pulling from row 10.
The yy
is the number of records/rows you want to pull from the table.
To build on the previous example: If table 1 has 40 records and you began pulling from row 10 and grab the NEXT set of 10 (yy
).
That would mean, the code above will pull the records from table 1 starting at row 10 and ending at 20. Thus pulling rows 10 - 20.

Sometimes if a Thread

/currentThread
sleep while ignoring interrupted Exception
catch(es), one interrupt might not be enough to completely exit execution.
In that case, we can supply these loop-based interrupts:
while(th.isAlive()){
log.trace("Still processing Internally; Sending Interrupt;");
th.interrupt();
try {
Thread.currentThread().sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}

Here's a Swift extension for UILabel. It runs a binary search algorithm to resize the font based off the width and height of the label's bounds. Tested to work with iOS 9 and autolayout.
USAGE: Where <label>
is your pre-defined UILabel that needs font resizing
<label>.fitFontForSize()
By Default, this function searches in within the range of 5pt and 300pt font sizes and sets the font to fit its text "perfectly" within the bounds (accurate within 1.0pt). You could define the parameters so that it, for example, searches between 1pt and the label's current font size accurately within 0.1pts in the following way:
<label>.fitFontForSize(1.0, maxFontSize: <label>.font.pointSize, accuracy:0.1)
Copy/Paste the following code into your file
extension UILabel {
func fitFontForSize(var minFontSize : CGFloat = 5.0, var maxFontSize : CGFloat = 300.0, accuracy : CGFloat = 1.0) {
assert(maxFontSize > minFontSize)
layoutIfNeeded() // Can be removed at your own discretion
let constrainedSize = bounds.size
while maxFontSize - minFontSize > accuracy {
let midFontSize : CGFloat = ((minFontSize + maxFontSize) / 2)
font = font.fontWithSize(midFontSize)
sizeToFit()
let checkSize : CGSize = bounds.size
if checkSize.height < constrainedSize.height && checkSize.width < constrainedSize.width {
minFontSize = midFontSize
} else {
maxFontSize = midFontSize
}
}
font = font.fontWithSize(minFontSize)
sizeToFit()
layoutIfNeeded() // Can be removed at your own discretion
}
}
NOTE: Each of the layoutIfNeeded()
calls can be removed at your own discretion

event.target
returns the node that was targeted by the function. This means you can do anything you want to do with any other node like one you'd get from document.getElementById
I'm tried with jQuery
var _target = e.target;
console.log(_target.attr('href'));
Return an error :
.attr not function
But _target.attributes.href.value
was works.
I my case I was not using /etc/nginx/sites-available/default
I was using a different server block configuration file (e.g. example.com), and the only way I was able to fix this problem is by removing the default server block configuration file symbolic link:
$ rm /etc/nginx/sites-enabled/default
then reloading Nginx:
$ sudo systemctl reload nginx
How about passing it as dp injection into that class? in ConfigureServices:
services.Configure<MyOptions>(Configuration);
create class to hold json strings:
public class MyOptions
{
public MyOptions()
{
}
public string Option1 { get; set; }
public string Option2 { get; set; }
}
Add strings to json file:
"option1": "somestring",
"option2": "someothersecretstring"
In classes that need these strings, pass in as constructor:
public class SomeClass
{
private readonly MyOptions _options;
public SomeClass(IOptions<MyOptions> options)
{
_options = options.Value;
}
public void UseStrings()
{
var option1 = _options.Option1;
var option2 = _options.Option2;
//code
}
}
Try this:
<?php echo "http://" . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; ?>
Learn more about the $_SERVER
predefined variable.
If you plan on using https, you can use this:
function url(){
return sprintf(
"%s://%s%s",
isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http',
$_SERVER['SERVER_NAME'],
$_SERVER['REQUEST_URI']
);
}
echo url();
#=> http://127.0.0.1/foo
Per this answer, please make sure to configure your Apache properly so you can safely depend on SERVER_NAME
.
<VirtualHost *>
ServerName example.com
UseCanonicalName on
</VirtualHost>
NOTE: If you're depending on the HTTP_HOST
key (which contains user input), you still have to make some cleanup, remove spaces, commas, carriage return, etc. Anything that is not a valid character for a domain. Check the PHP builtin parse_url function for an example.
Rather than search it in full Body. One could just use dynamic title option already available in such scenarios I think:
$btn.tooltip({
title: function(){
return $(this).attr('title');
}
});
read the documentation: matplotlib.pyplot.subplots
pyplot.subplots()
returns a tuple fig, ax
which is unpacked in two variables using the notation
fig, axes = plt.subplots(nrows=2, ncols=2)
the code
fig = plt.figure()
axes = fig.subplots(nrows=2, ncols=2)
does not work because subplots()
is a function in pyplot
not a member of the object Figure
.
Swift is not like languages like JavaScript, where you can call a function without passing the parameters and it will still be called. So to call a function in Swift, you need to assign a value to its parameters.
Default values for parameters allow you to assign a value without specifying it when calling the function. That's why test()
works when you specify a default value on test's declaration.
If you don't include that default value, you need to provide the value on the call: test(nil)
.
Also, and not directly related to this question, but probably worth to note, you are using the "C++" way of dealing with possibly null pointers, for dealing with possible nil optionals in Swift. The following code is safer (specially in multithreading software), and it allows you to avoid the forced unwrapping of the optional:
func test(firstThing: Int? = nil) {
if let firstThing = firstThing {
print(firstThing)
}
print("done")
}
test()
I know I am late but hope this helps.
Following are the values for the position property.
position : static
This is default. It means the element will occur at a position that it normally would.
#myelem {
position : static;
}
position : fixed
This will set the position of an element with respect to the browser window (viewport). A fixed positioned element will remain in its position even when the page scrolls.
(Ideal if you want scroll-to-top button at the bottom right corner of the page).
#myelem {
position : fixed;
bottom : 30px;
right : 30px;
}
position : relative
To place an element at a new location relative to its original position.
#myelem {
position : relative;
left : 30px;
top : 30px;
}
The above CSS will move the #myelem element 30px to the left and 30px from the top of its actual location.
position : absolute
If we want an element to be placed at an exact position in the page.
#myelem {
position : absolute;
top : 30px;
left : 300px;
}
The above CSS will position #myelem element at a position 30px from top and 300px from the left in the page and it will scroll with the page.
And finally...
position relative + absolute
We can set the position property of a parent element to relative and then set the position property of the child element to absolute. This way we can position the child relative to the parent at an absolute position.
#container {
position : relative;
}
#div-2 {
position : absolute;
top : 0;
right : 0;
}
We can see in the above image the #div-2 element is positioned at the top-right corner inside the #container element.
GitHub: You can find the HTML of the above image here and CSS here.
Hope this tutorial helps.
Try this:
<script>
document.addEventListener("touchstart", function(){}, true);
</script>
And in your CSS:
element:hover, element:active {
-webkit-tap-highlight-color: rgba(0,0,0,0);
-webkit-user-select: none;
-webkit-touch-callout: none /*only to disable context menu on long press*/
}
With this code you don't need an extra .hover class!
Within a module, to have a combination of flavors, flavor resources (layout, values) and flavors resource resources, the main thing to keep in mind are two things:
When adding resource directories in res.srcDirs
for flavor, keep in mind that in other modules and even in src/main/res
of the same module, resource directories are also added. Hence, the importance of using an add-on assignment (+=
) so as not to overwrite all existing resources with the new assignment.
The path that is declared as an element of the array is the one that contains the resource types, that is, the resource types are all the subdirectories that a res folder contains normally such as color, drawable, layout, values, etc. The name of the res folder can be changed.
An example would be to use the path "src/flavor/res/values/strings-ES"
but observe that the practice hierarchy has to have the subdirectory values
:
+-- module
+-- flavor
+-- res
+-- values
+-- strings-ES
+-- values
+-- strings.xml
+-- strings.xml
The framework recognizes resources precisely by type, that is why normally known subdirectories cannot be omitted.
Also keep in mind that all the strings.xml
files that are inside the flavor would form a union so that resources cannot be duplicated. And in turn this union that forms a file in the flavor has a higher order of precedence before the main of the module.
flavor {
res.srcDirs += [
"src/flavor/res/values/strings-ES"
]
}
Consider the strings-ES
directory as a custom-res which contains the resource types.

If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.
I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).
After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!
Keep in mind that python command will not be available from command line if you remove it from PATH.

From Wikipedia:
In PHP, the scope resolution operator is also called Paamayim Nekudotayim (Hebrew: ?????? ?????????), which means “double colon” in Hebrew.
The name "Paamayim Nekudotayim" was introduced in the Israeli-developed Zend Engine 0.5 used in PHP 3. Although it has been confusing to many developers who do not speak Hebrew, it is still being used in PHP 5, as in this sample error message:
$ php -r :: Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM
As of PHP 5.4, error messages concerning the scope resolution operator still include this name, but have clarified its meaning somewhat:
$ php -r :: Parse error: syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM)
From the official PHP documentation:
The Scope Resolution Operator (also called Paamayim Nekudotayim) or in simpler terms, the double colon, is a token that allows access to static, constant, and overridden properties or methods of a class.
When referencing these items from outside the class definition, use the name of the class.
As of PHP 5.3.0, it's possible to reference the class using a variable. The variable's value can not be a keyword (e.g. self, parent and static).
Paamayim Nekudotayim would, at first, seem like a strange choice for naming a double-colon. However, while writing the Zend Engine 0.5 (which powers PHP 3), that's what the Zend team decided to call it. It actually does mean double-colon - in Hebrew!

There is a way to mount a volume during a build, but it doesn't involve Dockerfiles.
The technique would be to create a container from whatever base you wanted to use (mounting your volume(s) in the container with the -v
option), run a shell script to do your image building work, then commit the container as an image when done.
Not only will this leave out the excess files you don't want (this is good for secure files as well, like SSH files), it also creates a single image. It has downsides: the commit command doesn't support all of the Dockerfile instructions, and it doesn't let you pick up when you left off if you need to edit your build script.
UPDATE:
For example,
CONTAINER_ID=$(docker run -dit ubuntu:16.04)
docker cp build.sh $CONTAINER_ID:/build.sh
docker exec -t $CONTAINER_ID /bin/sh -c '/bin/sh /build.sh'
docker commit $CONTAINER_ID $REPO:$TAG
docker stop $CONTAINER_ID
We could type our variable with an explicit return type:
const script: HTMLScriptElement = document.getElementsByName(id).item(0);
Or assert as (needed with TSX):
const script = document.getElementsByName(id).item(0) as HTMLScriptElement;
Or in simpler cases assert with angle-bracket syntax.
A type assertion is like a type cast in other languages, but performs no special checking or restructuring of data. It has no runtime impact, and is used purely by the compiler.

HTML5 does not require attributes to have values
It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.
Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.
DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj
...
The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.
var DyObjectsList = new List<dynamic>;
if (condition1) {
dynamic DyObj = new ExpandoObject();
DyObj.Required = true;
DyObj.Message = "Message 1";
DyObjectsList .Add(DyObj);
}
if (condition2) {
dynamic DyObj = new ExpandoObject();
DyObj.Required = false;
DyObj.Message = "Message 2";
DyObjectsList .Add(DyObj);
}
your resulting List essentially looks like this
DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj
Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.
However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.
#define
can accomplish some jobs that normal C++ cannot, like guarding headers and other tasks. However, it definitely should not be used as a magic number- a static const should be used instead.
You can actually use angular-ui-utils' ui-route
directive:
<a ui-route ng-href="/">Home</a>
<a ui-route ng-href="/about">About</a>
<a ui-route ng-href="/contact">Contact</a>
or:
/**
* Header controller
*/
angular.module('myApp')
.controller('HeaderCtrl', function ($scope) {
$scope.menuItems = [
{
name: 'Home',
url: '/',
title: 'Go to homepage.'
},
{
name: 'About',
url: '/about',
title: 'Learn about the project.'
},
{
name: 'Contact',
url: '/contact',
title: 'Contact us.'
}
];
});
<!-- index.html: -->
<div class="header" ng-controller="HeaderCtrl">
<ul class="nav navbar-nav navbar-right">
<li ui-route="{{menuItem.url}}" ng-class="{active: $uiRoute}"
ng-repeat="menuItem in menuItems">
<a ng-href="#{{menuItem.url}}" title="{{menuItem.title}}">
{{menuItem.name}}
</a>
</li>
</ul>
</div>
If you're using ui-utils, you may also be interested in ui-router for managing partial/nested views.
Bootstrap naming conventions carry styles of their own, col-XS-1 refers to a column being 8.33% of the containing element wide. Your text, would most likely expand far beyond the specified width, and couldn't possible be centered within it. If you wanted it to constrain to the div, you could use something like css word-break.
For centering the content within an element large enough to expand beyond the text, you have two options.
Option 1: HTML Center Tag
<div class="row">
<div class="col-xs-1 center-block">
<center>
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</center>
</div>
</div>
Option 2: CSS Text-Align
<div class="row">
<div class="col-xs-1 center-block" style="text-align:center;">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
If you wanted everything to constrain to the width of the column
<div class="row">
<div class="col-xs-1 center-block" style="text-align:center;word-break:break-all;">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
UPDATE - Using Bootstrap's text-center class
<div class="row">
<div class="col-xs-1 center-block text-center">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>
FlexBox Method
<div class="row">
<div class="flexBox" style="
display: flex;
flex-flow: row wrap;
justify-content: center;">
<span>aaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
</div>
</div>

Building on RobertoNovelo's answer:
import * as fs from 'fs';
is currently the simplest way to do it.
It was tested with a Node.js project (Node.js v10.15.3), with esm, allowing to use import
.
Another way would be to get the Enumerator and call the MoveNext() method to see if there are any items:
if (mylist != null && mylist.GetEnumerator().MoveNext())
{
// The list is not null or empty
}
This works for IEnumerable as well as IEnumerable<T>.
I use a solution that is similar to that of David above, but with an additional twist if some rows should be excluded from the count. This assumes that [UserAccountKey] is never null.
-- subtract an extra 1 if null was ranked within the partition,
-- which only happens if there were rows where [Include] <> 'Y'
dense_rank() over (
partition by [Mth]
order by case when [Include] = 'Y' then [UserAccountKey] else null end asc
)
+ dense_rank() over (
partition by [Mth]
order by case when [Include] = 'Y' then [UserAccountKey] else null end desc
)
- max(case when [Include] = 'Y' then 0 else 1 end) over (partition by [Mth])
- 1
Since sockstat wasn't natively installed on my machine I hacked up stanwise's answer to use netstat instead..
netstat -nlp | grep -E "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\:2000" | awk '{print $7}' | sed -e "s/\/.*//g""
In my case the problem occured when i forgot to add the =0 on one function in my pure virtual class. It was fixed when the =0 was added. The same as for Frank above.
class ISettings
{
public:
virtual ~ISettings() {};
virtual void OKFunction() =0;
virtual void ProblemFunction(); // missing =0
};
class Settings : ISettings
{
virtual ~Settings() {};
void OKFunction();
void ProblemFunction();
};
void Settings::OKFunction()
{
//stuff
}
void Settings::ProblemFunction()
{
//stuff
}
I got a 503 error because the Application Pools weren't started in IIS for some reason.
try this:
.button input, .button a {
//css here
}
That will apply the style to all a tags nested inside of <p class="button"></p>
First you need to import svg
files by following simple steps.
If image is available in your computer
then select local svg
file.
After that select the image path
and an option to change the size of the image is also available at the right side of dialog if you want to .
in this way svg
image is imported in your project
After that for using this image use the same procedure
@drawable/yourimagename
dir, err := os.Getwd()
if err != nil {
fmt.Println(err)
}
this is for golang version: go version go1.13.7 linux/amd64
works for me, for go run main.go
. If I run go build -o fileName
, and put the final executable in some other folder, then that path is given while running the executable.
(And if you have no admin access to the server)
ALTER ROLE <your_login_role> SET search_path TO a,b,c;
Two important things to know about:
a, b, c
matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path
.You can use pandas.Dataframe.isin
.
pandas.Dateframe.isin
will return boolean values depending on whether each element is inside the list a
or not. You then invert this with the ~
to convert True
to False
and vice versa.
import pandas as pd
a = ['2015-01-01' , '2015-02-01']
df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})
print(df)
# date
#0 2015-01-01
#1 2015-02-01
#2 2015-03-01
#3 2015-04-01
#4 2015-05-01
#5 2015-06-01
df = df[~df['date'].isin(a)]
print(df)
# date
#2 2015-03-01
#3 2015-04-01
#4 2015-05-01
#5 2015-06-01
You can try by adding this line
card_view:cardUseCompatPadding="true"
The Whole code will seems like this
<android.support.v7.widget.CardView

xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="5dp"
android:orientation="horizontal"
card_view:cardUseCompatPadding="true"
card_view:cardCornerRadius="5dp">
</android.support.v7.widget.CardView
You define var scatterSeries = [];
, and then try to parse it as a json string at console.info(JSON.parse(scatterSeries));
which obviously fails. The variable is converted to an empty string, which causes an "unexpected end of input" error when trying to parse it.
You can use an extension method like this:
internal static class ArrayExt
{
public static IEnumerable<int> Indices(this Array array, int dimension)
{
for (var i = array.GetLowerBound(dimension); i <= array.GetUpperBound(dimension); i++)
{
yield return i;
}
}
}
And then:
int[,] array = { { 1, 2, 3 }, { 4, 5, 6 } };
foreach (var i in array.Indices(0))
{
foreach (var j in array.Indices(1))
{
Console.Write(array[i, j]);
}
Console.WriteLine();
}
It will be a bit slower than using for loops but probably not an issue in most cases. Not sure if it makes things more readable.
Note that c# arrays can be other than zero-based so you can use a for loop like this:
int[,] array = { { 1, 2, 3 }, { 4, 5, 6 } };
for (var i = array.GetLowerBound(0); i <= array.GetUpperBound(0); i++)
{
for (var j= array.GetLowerBound(1); j <= array.GetUpperBound(1); j++)
{
Console.Write(array[i, j]);
}
Console.WriteLine();
}

In order to store Strings in an dynamic array (add-method) you can't define it as an array of integers ( int[3] ). You should declare it like this:
ArrayList<String> alist = new ArrayList<String>();
alist.add("apple");
alist.add("banana");
alist.add("orange");
System.out.println( alist.get(1) );

i've mandained some similar page (classic asp...)
my approach was to use Q promise directly on the popup.
For example my problem was that the popup i wanted to print close itself too fast ... and the print previw was empty, i solved this way :
Caller :
var popup = window.open("index.asp","popupwindow","width=800,height=500,left=200,top=5,scrollbars,toolbar=0,resizable");
Popup (at the end of the page):
<script src="/Scripts/jquery-1.9.1.min.js"></script>
<script src="/Scripts/q.min.js"></script>
<script type="text/javascript">
Q(window.print()).then(function () {window.close();});
</script>
I think that your "parent lock" could be solved in a similar way
i would try :
var w = whatever;
Q(
// fill your popup
).then(function () {
w.print();
}).then(function () {
w.close();
});
that makes "the print" and "the close" async... so the parent will be immediately "unlocked"
Like the other answers you can do theTypeIs = Object.keys(myVar)[0];
to get the first key. If you are expecting more keys, you can use
Object.keys(myVar).forEach(function(k) {
if(k === "typeA") {
// do stuff
}
else if (k === "typeB") {
// do more stuff
}
else {
// do something
}
});
In your JSON format, it do not have starting JSON object
Like :
{
"info" : <!-- this is starting JSON object -->
{
"caller":"getPoiById",
"results":
{
"indexForPhone":0,
"indexForEmail":"NULL",
.
.
}
}
}
Above Json starts with info
as JSON object. So while executing :
JSONObject json = new JSONObject(result); // create JSON obj from string
JSONObject json2 = json.getJSONObject("info"); // this will return correct
Now, we can access result
field :
JSONObject jsonResult = json2.getJSONObject("results");
test = json2.getString("name"); // returns "Marina Rasche Werft GmbH & Co. KG"
I think this was missing and so the problem was solved while we use JSONTokener
like answer of yours.
Your answer is very fine. Just i think i add this information so i answered
Thank you
I'm not very advanced in AngularJS, but my solution would be to use a simple JS class for you cart (in the sense of coffee script) that extend Array.
The beauty of AngularJS is that you can pass you "model" object with ng-click like shown below.
I don't understand the advantage of using a factory, as I find it less pretty that a CoffeeScript class.
My solution could be transformed in a Service, for reusable purpose. But otherwise I don't see any advantage of using tools like factory or service.
class Basket extends Array
constructor: ->
add: (item) ->
@push(item)
remove: (item) ->
index = @indexOf(item)
@.splice(index, 1)

@indexOf(item) isnt -1
indexOf: (item) ->
indexOf = -1
@.forEach (stored_item, index) ->
if (item.id is stored_item.id)
indexOf = index
return indexOf
Then you initialize this in your controller and create a function for that action:
$scope.basket = new Basket()
$scope.addItemToBasket = (item) ->
$scope.basket.add(item)
Finally you set up a ng-click to an anchor, here you pass your object (retreived from the database as JSON object) to the function:
li ng-repeat="item in items"
a href="#" ng-click="addItemToBasket(item)"
try Parsing and Formatting
Take an example Parsing
String input = ...;
try {
DateTimeFormatter formatter =
DateTimeFormatter.ofPattern("MMM d yyyy");
LocalDate date = LocalDate.parse(input, formatter);
System.out.printf("%s%n", date);
}
catch (DateTimeParseException exc) {
System.out.printf("%s is not parsable!%n", input);
throw exc; // Rethrow the exception.
}
Formatting
ZoneId leavingZone = ...;
ZonedDateTime departure = ...;
try {
DateTimeFormatter format = DateTimeFormatter.ofPattern("MMM d yyyy hh:mm a");
String out = departure.format(format);
System.out.printf("LEAVING: %s (%s)%n", out, leavingZone);
}
catch (DateTimeException exc) {
System.out.printf("%s can't be formatted!%n", departure);
throw exc;
}
The output for this example, which prints both the arrival and departure time, is as follows:
LEAVING: Jul 20 2013 07:30 PM (America/Los_Angeles)
ARRIVING: Jul 21 2013 10:20 PM (Asia/Tokyo)

I agree with Cade Roux.
This article should get you on the right track:
One thing to note, clustered indexes should have a unique key (an identity column I would recommend) as the first column. Basically it helps your data insert at the end of the index and not cause lots of disk IO and Page splits.
Secondly, if you are creating other indexes on your data and they are constructed cleverly they will be reused.
e.g. imagine you search a table on three columns
state, county, zip.
Then an index with state, county, zip. will be used in all three of these searches.
If you search by zip alone quite a lot then the above index will not be used (by SQL Server anyway) as zip is the third part of that index and the query optimiser will not see that index as helpful.
You could then create an index on Zip alone that would be used in this instance.
By the way We can take advantage of the fact that with Multi-Column indexing the first index column is always usable for searching and when you search only by 'state' it is efficient but yet not as efficient as Single-Column index on 'state'
I guess the answer you are looking for is that it depends on your where clauses of your frequently used queries and also your group by's.
The article will help a lot. :-)
It means that:
public
- it can be called from anywherestatic
- it doesn't have any object state, so you can call it without instantiating an objectvoid
- it doesn't return anythingYou'd think that the lack of a return means it isn't doing much, but it might be saving things in the database, for example.
The ready event is always execute at the only html page is loaded to the browser and the functions are executed.... But the load event is executed at the time of all the page contents are loaded to the browser for the page..... we can use $ or jQuery when we use the noconflict() method in jquery scripts...
just to complet, a proc stored using except method to compare 2 tables and give result in same table with 3 errors status, ADD, DEL, GAP table must have same PK, you declare the 2 tables and fields to compare of 1 or both table
Just use like this ps_TableGap 'tbl1','Tbl2','fld1,fld2,fld3','fld4'fld5'fld6' (optional)

Why are there extra spaces between my month and day? Why does't it just put them next to each other?
So your output will be aligned.
If you don't want padding use the format modifier FM
:
SELECT TO_CHAR (date_field, 'fmMonth DD, YYYY')
FROM ...;
Reference: Format Model Modifiers
Have a look at this:
https://github.com/kmike/marisa-trie
Static memory-efficient Trie structures for Python (2.x and 3.x).
String data in a MARISA-trie may take up to 50x-100x less memory than in a standard Python dict; the raw lookup speed is comparable; trie also provides fast advanced methods like prefix search.
Based on marisa-trie C++ library.
Here's a blog post from a company using marisa trie successfully:
https://www.repustate.com/blog/sharing-large-data-structure-across-processes-python/
At Repustate, much of our data models we use in our text analysis can be represented as simple key-value pairs, or dictionaries in Python lingo. In our particular case, our dictionaries are massive, a few hundred MB each, and they need to be accessed constantly. In fact for a given HTTP request, 4 or 5 models might be accessed, each doing 20-30 lookups. So the problem we face is how do we keep things fast for the client as well as light as possible for the server.
...
I found this package, marisa tries, which is a Python wrapper around a C++ implementation of a marisa trie. “Marisa” is an acronym for Matching Algorithm with Recursively Implemented StorAge. What’s great about marisa tries is the storage mechanism really shrinks how much memory you need. The author of the Python plugin claimed 50-100X reduction in size – our experience is similar.
What’s great about the marisa trie package is that the underlying trie structure can be written to disk and then read in via a memory mapped object. With a memory mapped marisa trie, all of our requirements are now met. Our server’s memory usage went down dramatically, by about 40%, and our performance was unchanged from when we used Python’s dictionary implementation.
There are also a couple of pure-python implementations, though unless you're on a restricted platform you'd want to use the C++ backed implementation above for best performance:
Try
string reversed(temp.rbegin(), temp.rend());
EDIT: Elaborating as requested.
string::rbegin()
and string::rend()
, which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator*
to dereference to an element, i.e. a character of the string, and operator++
to advance to the "next" element), such that rbegin()
points to the last character of the string, rend()
points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).
Finally, the constructor we are passing these iterators into is a string constructor of the form:
template <typename Iterator>
string(Iterator first, Iterator last);
which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.
You can try using fast-export:
cd ~
git clone https://github.com/frej/fast-export.git
git init git_repo
cd git_repo
~/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo
git checkout HEAD
Also have a look at this SO question.
If you're using Mercurial version below 4.6, adrihanu got your back:
As he stated in his comment: "In case you use Mercurial < 4.6 and you got "revsymbol not found" error. You need to update your Mercurial or downgrade fast-export by running git checkout tags/v180317 inside ~/fast-export directory.".
Use the pointtype
and pointsize
options, e.g.
plot "./points.dat" using 1:2 pt 7 ps 10
where pt 7
gives you a filled circle and ps 10
is the size.
See: Plotting data.
I looked for a C/C++ API for Google Voice for quite a while and never found anything close (the closest was a C# API). Since I really needed it, I decided to just write one myself:

I hope others find it useful. Feedback and suggestions welcome.
The flexbox grid should do what you want. You're not clear as to what limitation you ran into, so it's hard to address your specifics.

You can simply use DataColumnCollection.IndexOf
So that you can get the index of the required column by name then use it with your row:
row[dt.Columns.IndexOf("ColumnName")] = columnValue;
I also have just faced with this problem that how to open existing file. And none of answers was helpful. That's why I tried by myself.
Direction: File -> Open file -> Workspace (with you had chosen first in creating your project) -> Package (which you already created your project in) -> src (source file) -> Created package ->
And now your searching project's nodepad format. I hope it would be helpful. If any mistake here, sorry beforehand.
#define MULTILINE(...) #__VA_ARGS__
Consumes everything between the parentheses.
Replaces any number of consecutive whitespace characters by a single space.
Some of the answers to this question are outdated.
What worked for me (in 2020) was to explicitly tell the intent to skip the chooser and directly open the play store app, according to this link:
"If you want to link to your products from an Android app, create an Intent that opens a URL. As you configure this intent, pass "com.android.vending" into Intent.setPackage() so that users see your app's details in the Google Play Store app instead of a chooser."
This is the Kotlin code I used to direct users to viewing the app containing the package name com.google.android.apps.maps in Google Play:
val intent = Intent(Intent.ACTION_VIEW).apply {
data = Uri.parse("http://play.google.com/store/apps/details?id=com.google.android.apps.maps")
setPackage("com.android.vending")
}
startActivity(intent)
I hope that helps someone!
To avoid a global install, add Nodemon as a dependency, then...
package.json
"scripts": {
"start": "node ./bin/www",
"start-dev": "./node_modules/nodemon/bin/nodemon.js ./bin/www"
},
Not mentioned so far, is that DEFAULT CURRENT_TIMESTAMP only works with Timestamp, but not DateTime type fields.
This becomes relevant for MS Access tables which can only use DateTime but not Timestamp.
Use next, it will bypass that condition and rest of the code will work. Below i have provided the Full script and out put
class TestBreak
puts " Enter the nmber"
no= gets.to_i
for i in 1..no
if(i==5)
next
else
puts i
end
end
end
obj=TestBreak.new()
Output: Enter the nmber 10
1 2 3 4 6 7 8 9 10
Another alternative might be
Array.from(document.querySelectorAll("a")).map(x => x.href)
With your $$(
its even shorter
Array.from($$("a")).map(x => x.href)
You may interest in using php's inbuilt function realpath(). and passing a constant DIR
for example: $TargetDirectory = realpath(__DIR__."/../.."); //Will take you 2 folder's back
String realpath() :: Returns canonicalized absolute pathname ..
I've tried a select statement now with a PreparedStatement
, but it turned out that it was not faster than the Jdbc template. Maybe, as mezmo suggested, it automatically creates prepared statements.
Anyway, the reason for my sql SELECT
s being so slow was another one. In the WHERE
clause I always used the operator LIKE
, when all I wanted to do was finding an exact match. As I've found out LIKE
searches for a pattern and therefore is pretty slow.
I'm using the operator =
now and it's much faster.
As others have mentioned, app on Android can't write a file to any folder the internal storage but their own private storage (which is under /data/data/PACKAGE_NAME ).
You should use the API to get the correct path that is allowed for your app.
read this .
You need to use the select new
LINQ keyword to explicitly convert your tbcourse
entity into the custom type course
. Example of select new
:
var q = from o in db.Orders
where o.Products.ProductName.StartsWith("Asset") &&
o.PaymentApproved == true
select new { name = o.Contacts.FirstName + " " +
o.Contacts.LastName,
product = o.Products.ProductName,
version = o.Products.Version +
(o.Products.SubVersion * 0.1)
};
You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:
import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values
... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.
http://caniuse.com/#search=::after
::after
and ::before
with content
are better to use as they're supported in every major browser other than Internet Explorer at least 5 versions back. Internet Explorer has complete support in version 9+ and partial support in version 8.
Is this what you're looking for?
.Modal::after{
content:url('blackCarrot.png'); /* with class ModalCarrot ??*/
position:relative; /*or absolute*/
z-index:100000; /*a number that's more than the modal box*/
left:-50px;
top:10px;
}
.ModalCarrot{
position:absolute;
left:50%;
margin-left:-8px;
top:-16px;
}
If not, can you explain a little better?
or you could use jQuery, like Joshua said:
$(".Modal").before("<img src='blackCarrot.png' class='ModalCarrot' />");
You can use this library, makes it seamless to send push notifications using Firebase Service from a C# backend download here
$(document).ready(function() {
//...
//clear on focus
$('.input').focus(function() {
$('.input').val("");
});
//clear when submitted
$('.button').click(function() {
$('.input').val("");
});
});
The method I prefer assigns an array of data to the combobox. Click on the body of your userform and change the "Click" event to "Initialize". Now the combobox will fill upon the initializing of the userform. I hope this helps.
Sub UserForm_Initialize()
ComboBox1.List = Array("1001", "1002", "1003", "1004", "1005", "1006", "1007", "1008", "1009", "1010")
End Sub
You can't use an aggregate directly in a WHERE clause; that's what HAVING clauses are for.
You can use a sub-query which contains an aggregate in the WHERE clause.
Well, your solution almost works. There are a few things to take into account to keep it simple:
Cancel the default navigation only for specific URLs you know a download will occur, or the user won't be able to navigate anywhere. This means you musn't change your website download URLs.
DownloadFileAsync
doesn't know the name reported by the server in the Content-Disposition
header so you have to specify one, or compute one from the original URL if that's possible. You cannot just specify the folder and expect the file name to be retrieved automatically.
You have to handle download server errors from the DownloadCompleted
callback because the web browser control won't do it for you anymore.
Sample piece of code, that will download into the directory specified in textBox1
, but with a random file name, and without any additional error handling:
private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) {
/* change this to match your URL. For example, if the URL always is something like "getfile.php?file=xxx", try e.Url.ToString().Contains("getfile.php?") */
if (e.Url.ToString().EndsWith(".zip")) {
e.Cancel = true;
string filePath = Path.Combine(textBox1.Text, Path.GetRandomFileName());
var client = new WebClient();
client.DownloadFileCompleted += client_DownloadFileCompleted;
client.DownloadFileAsync(e.Url, filePath);
}
}
private void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e) {
MessageBox.Show("File downloaded");
}
This solution should work but can be broken very easily. Try to consider some web service listing the available files for download and make a custom UI for it. It'll be simpler and you will control the whole process.
LIMIT 1
is what you want. Just keep in mind this returns the first record in the result set regardless of order (unless you specify an order
clause in an outer query).
Starting from API 21, the GridLayout now supports the weight like LinearLayout. For details please see the link below:

Because 1
is numeric, but not integer (i.e. it's a floating point number), and 1:6000
is numeric and integer.
> print(class(1))
[1] "numeric"
> print(class(1:60000))
[1] "integer"
60000 squared is 3.6 billion, which is NOT representable in signed 32-bit integer, hence you get an overflow error:
> as.integer(60000)*as.integer(60000)
[1] NA
Warning message:
In as.integer(60000) * as.integer(60000) : NAs produced by integer overflow
3.6 billion is easily representable in floating point, however:
> as.single(60000)*as.single(60000)
[1] 3.6e+09
To fix your for
code, convert to a floating point representation:
function (N)
{
for(i in as.single(1:N)) {
y <- i*i
}
}
You need to pass an array of element to jsx
. The problem is that forEach
does not return anything (i.e it returns undefined
). So it's better to use map
because map
returns an array:
class QuestionSet extends Component {
render(){
<div className="container">
<h1>{this.props.question.text}</h1>
{this.props.question.answers.map((answer, i) => {
console.log("Entered");
// Return the element. Also pass key
return (<Answer key={answer} answer={answer} />)
})}
}
export default QuestionSet;
The way to do was looking at the code in code/core/Mage/Catalog/Model/Resource/Category/Flat/Collection.php
at line 380 in Magento 1.7.2 on the function setPage($pageNum, $pageSize)
$collection = Mage::getModel('model')
->getCollection()
->setCurPage(2) // 2nd page
->setPageSize(10); // 10 elements per pages
I hope this will help someone.
Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf
between host and guest (there is known performance issues if there are large numbers of files/directories).
/vagrant
in guestVagrant is mounting the current working directory (where Vagrantfile
resides) as /vagrant
in the guest, this is the default behaviour.

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.
You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true
in your Vagrantfile
.
Based on the output /tmp
on host was NOT mounted during up time.
Use VAGRANT_INFO=debug vagrant up
or VAGRANT_INFO=debug vagrant reload
to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp
on host should be drwxrwxrwt
).
I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)
config.vm.synced_folder "/tmp", "/tmp/src"
output

Android doesn't have special code for sending and receiving HTTP, you can use standard Java code. I'd recommend using the Apache HTTP client, which comes with Android. Here's a snippet of code I used to send an HTTP POST.
I don't understand what sending the object in a variable named "jason" has to do with anything. If you're not sure what exactly the server wants, consider writing a test program to send various strings to the server until you know what format it needs to be in.
int TIMEOUT_MILLISEC = 10000; // = 10 seconds
String postMessage="{}"; //HERE_YOUR_POST_STRING.
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);
HttpPost request = new HttpPost(serverUrl);
request.setEntity(new ByteArrayEntity(
postMessage.toString().getBytes("UTF8")));
HttpResponse response = client.execute(request);
More compact version working with spaces and newlines in the file name:
find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;
Too difficult :)

Start phpMyAdmin and access wp_users from your wordpress instance. Edit record and select user_pass function to match MD5. Write the string that will be your new password in VALUE. Click, GO. Go to your wordpress website and enter your new password. Back to phpMyAdmin you will see that WP changed the HASH to something like $P$B... enjoy!
Just remove the throw
from the catch block — change it to an echo
or otherwise handle the error.
It's not telling you that objects can only be thrown in the catch block, it's telling you that only objects can be thrown, and the location of the error is in the catch block — there is a difference.
In the catch block you are trying to throw something you just caught — which in this context makes little sense anyway — and the thing you are trying to throw is a string.
A real-world analogy of what you are doing is catching a ball, then trying to throw just the manufacturer's logo somewhere else. You can only throw a whole object, not a property of the object.
I believe that the above answers is all correct, but that doesn't point out why the submit
method doesn't work.
Well, the submit
method will not work if jQuery can't get the form
element, and jQuery doesn't give any error about that. If your script is placed in the head of the document, make sure the code runs after DOM
is ready. So, $(document).ready(function () { // your code here // });
will solve the problem.
The best practice is, always put your script in the bottom of the document.
I had csrf enabled in my sprint security xml file, so I just added one line in the form:
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
This way I was able to submit the form having the model
attribute.
I tried to give a simple explanation in my blogpost.
requires 32 bits (4 bytes) to encode any character. For example, in order to represent the "A" character code-point using this scheme, you'll need to write 65 in 32-bit binary number:
00000000 00000000 00000000 01000001 (Big Endian)
If you take a closer look, you'll note that the most-right seven bits are actually the same bits when using the ASCII scheme. But since UTF-32 is fixed width scheme, we must attach three additional bytes. Meaning that if we have two files that only contain the "A" character, one is ASCII-encoded and the other is UTF-32 encoded, their size will be 1 byte and 4 bytes correspondingly.
Many people think that as UTF-32 uses fixed width 32 bit to represent a code-point, UTF-16 is fixed width 16 bits. WRONG!
In UTF-16 the code point maybe represented either in 16 bits, OR 32 bits. So this scheme is variable length encoding system. What is the advantage over the UTF-32? At least for ASCII, the size of files won't be 4 times the original (but still twice), so we're still not ASCII backward compatible.
Since 7-bits are enough to represent the "A" character, we can now use 2 bytes instead of 4 like the UTF-32. It'll look like:
00000000 01000001
You guessed right.. In UTF-8 the code point maybe represented using either 32, 16, 24 or 8 bits, and as the UTF-16 system, this one is also variable length encoding system.
Finally we can represent "A" in the same way we represent it using ASCII encoding system:
01001101
Consider the Chinese letter "?" - its UTF-8 encoding is:
11101000 10101010 10011110
While its UTF-16 encoding is shorter:
10001010 10011110
In order to understand the representation and how it's interpreted, visit the original post.
I was having the same issue and this works excellently.

See Tejas Lagvankar's post about this subject. Below are some key differences between Service and IntentService and other components.
All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)
Based on this related answer, you are looking at a list that looks like: A-Z
, a-z
, 0-9
, -
, .
, _
, ~
, :
, /
, ?
, #
, [
, ]
, @
, !
, $
, &
, '
, (
, )
, *
, +
, ,
, ;
, %
, and =
. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. %
can only be used in conjunction with url encoding as in %20
), the RFC has all of these specifics.
In addition to the above answers here is how you might handle a 500 series response from your api where you receive an error message encoded in json:
function callApi(url) {
return fetch(url)
.then(response => {
if (response.ok) {
return response.json().then(response => ({ response }));
}
return response.json().then(error => ({ error }));
})
;
}
let url = 'http://jsonplaceholder.typicode.com/posts/6';
const { response, error } = callApi(url);
if (response) {
// handle json decoded response
} else {
// handle json decoded 500 series response
}
it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:
from scipy.stats import ttest_ind
cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']
ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)
it returns a tuple with the t-statistic & the p-value
see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

If the class implements the method directly, it will not use the traits version. Perhaps what you are thinking of is:
trait A {
function calc($v) {
return $v+1;
}
}
class MyClass {
function calc($v) {
return $v+2;
}
}
class MyChildClass extends MyClass{
}
class MyTraitChildClass extends MyClass{
use A;
}
print (new MyChildClass())->calc(2); // will print 4
print (new MyTraitChildClass())->calc(2); // will print 3
Because the child classes do not implement the method directly, they will first use that of the trait if there otherwise use that of the parent class.
If you want, the trait can use method in the parent class (assuming you know the method would be there) e.g.
trait A {
function calc($v) {
return parent::calc($v*3);
}
}
// .... other code from above
print (new MyTraitChildClass())->calc(2); // will print 8 (2*3 + 2)
You can also provide for ways to override, but still access the trait method as follows:
trait A {
function trait_calc($v) {
return $v*3;
}
}
class MyClass {
function calc($v) {
return $v+2;
}
}
class MyTraitChildClass extends MyClass{
use A {
A::trait_calc as calc;
}
}
class MySecondTraitChildClass extends MyClass{
use A {
A::trait_calc as calc;
}
public function calc($v) {
return $this->trait_calc($v)+.5;
}
}
print (new MyTraitChildClass())->calc(2); // will print 6
echo "\n";
print (new MySecondTraitChildClass())->calc(2); // will print 6.5

The error you're getting is that self.adj
doesn't already have a key 0
. You're trying to append to a list that doesn't exist yet.
Consider using a defaultdict
instead, replacing this line (in __init__
):
self.adj = {}
with this:
self.adj = defaultdict(list)
You'll need to import at the top:
from collections import defaultdict
Now rather than raise a KeyError
, self.adj[0].append(edge)
will create a list automatically to append to.
You can still use HttpResponseMessage
. That capability will not go away. I felt the same way as you and argued extensively with the team that there was no need for an additional abstraction. There were a few arguments thrown around to try and justify its existence but nothing that convinced me that it was worthwhile.
That is, until I saw this sample from Brad Wilson. If you construct IHttpActionResult
classes in a way that can be chained, you gain the ability to create a "action-level" response pipeline for generating the HttpResponseMessage
. Under the covers, this is how ActionFilters
are implemented however, the ordering of those ActionFilters
is not obvious when reading the action method which is one reason I'm not a fan of action filters.
However, by creating an IHttpActionResult
that can be explicitly chained in your action method you can compose all kinds of different behaviour to generate your response.
There's no way of calling (eg) printf without knowing how many arguments you're passing to it, unless you want to get into naughty and non-portable tricks.
The generally used solution is to always provide an alternate form of vararg functions, so printf
has vprintf
which takes a va_list
in place of the ...
. The ...
versions are just wrappers around the va_list
versions.
You can try this:
<a href="link.html">
<input type="button" value="Visit Page" />
</a>
This will create button inside a link and it works on any browser
This may not be a technical solution, but it works. (if anyone of your teammate has the same branch in local)

Note: Again, this is not a technical solution, but it will help for sure.
BalusC said:
Update: to clarify a conceptual misunderstanding, the sleep() is not required. It is just used for SSCCE/demonstration purposes. Just do your long running task right there in place of sleep().
But if you replace Thread.sleep(4000);
with for (int i = 0; i < 5E8; i++) {}
then it doesn't compile, because the empty loop doesn't throw an InterruptedException
.
And for the thread to be interruptible, it needs to throw an InterruptedException
.
This seems like a serious problem to me. I can't see how to adapt this answer to work with a general long-running task.
Edited to add: I reasked this as a new question: [ interrupting a thread after fixed time, does it have to throw InterruptedException? ]
In my case,
word-break: break-all;
worked perfecly, hope it helps any other newcomer like me.
Here is a one-liner for you.
Replace $jQueryObject
with your jQuery object. i.e $('div')
.
Object.values($jQueryObject.get(0).attributes).map(attr => console.log(`${attr.name + ' : ' + attr.value}`));
Replace $domElement
with your HTML DOM selector. i.e document.getElementById('demo')
.
Object.values($domElement.attributes).map(attr => console.log(`${attr.name + ' : ' + attr.value}`));
Cheers!!
I faced a problem upgrading pip from version 9.0.1 to 9.0.3 The upgrade failed middle way(after uninstalling version 9.0.1 and without installing version 9.0.3). This usually creates a broken pip file. Broken pip can be solved by the command-->
easy_install pip
Which usually installs the latest version of pip, and solves the issue. In order to confirm, type
pip --version
Hope this was helpfull...
While all of the other answers work, they all have one big problem: it is up to the browser to decide what to do if they encounter a Location header. Usually browser stop processing the request and redirect to the URI indicated with the Location header. But a malicious user could just ignore the Location header and continue its request. Furthermore there may be other things that cause the php interpreter to continue evaluating the script past the Location header, which is not what you intended.
Image this:
<?php
if (!logged_id()) {
header("Location:login.php");
}
delete_everything();
?>
What you want and expected is that not logged in users are redirected to the login page, so that only logged in users can delete_everything. But if the script gets executed past the Location header still everything gets deleted. Thus, it is import to ALWAYS put an exit after a Location header, like this:
<?php
if (!logged_id()) {
header("Location:login.php");
exit; // <- don't forget this!
}
delete_everything();
?>
So, to answer your question: to redirect from a php page to another page (not just php, you can redirect to any page this way), use this:
<?php
header("Location:http://www.example.com/some_page.php");
exit; // <- don't forget this!
?>
Small note: the HTTP standard says that you must provide absolute URLs in the Location header (http://... like in my example above) even if you just want to redirect to another file on the same domain. But in practice relative URLs (Location:some_page.php) work in all browsers, though not being standard compliant.
Your modifications are in a different branch than the original branch, which simplifies stuff because you get updates in one branch, and your work is in another branch.
Assuming the original branch is named master
, which the case in 99% of git repos, you have to fetch the state of origin, and merge origin/master
updates into your local master
:
git fetch origin
git checkout master
git merge origin/master
To switch to your branch, just do
git checkout branch1
You need to have a height in the div <div style="overflow:hidden">
else it doesnt know what 100%
is.
If you know the number of tables and their names, and assuming they each have primary keys, you can use a cross join in combination with COUNT(distinct [column])
to get the rows that come from each table:
SELECT
COUNT(distinct t1.id) +
COUNT(distinct t2.id) +
COUNT(distinct t3.id) AS totalRows
FROM firstTable t1, secondTable t2, thirdTable t3;
Here is an SQL Fiddle example.
In addition to Mark's answer, you also need to be aware of scope, which (as in C/C++) is specified using braces. So:
if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
return;
will always return at that point. However:
if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
{
textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
return;
}
will only return if it goes into that if
statement.
You can use git config
command to write a new rule to .git/config
to fetch pull requests from the repository:
$ git config --local --add remote.origin.fetch '+refs/pull/*/head:refs/remotes/origin/pr/*'
And then just:
$ git fetch origin
Fetching origin

You can use any on process for dynamic path on command prompt
Process p = Runtime.getRuntime().exec("cmd.exe /c start dir ");
Process p = Runtime.getRuntime().exec("cmd.exe /c start cd \"E:\\rakhee\\Obligation Extractions\" && dir");
Process p = Runtime.getRuntime().exec("cmd.exe /c start cd \"E:\\oxyzen-workspace\\BrightleafDesktop\\Obligation Extractions\" && dir");
Do this:
driver.ExecuteScript("window.open('your URL', '_blank');");
you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.
Not IsNull(Fields!W_O_Count.Value)
It looks a little odd, even silly, but this is working for me:
input.val(lastQuery);
input.focus().val(input.val());
Now, I'm not certain I've replicated your setup. I'm assuming input
is an <input>
element.
By re-setting the value (to itself) I think the cursor is getting put at the end of the input. Tested in Firefox 3 and MSIE7.
As of C# 6 you can declare and initialise a 'read-only auto-property' in one line:
double FuelConsumption { get; } = 2;
You can set the value from the constructor but not other methods.
As JoshC said, the class .sr-only
is used to visually hide the information used for screen readers only. But not only to hide labels. You might consider hiding various other elements such as "skip to main content" link, icons which have an alternative texts etc.
BTW. you can also use .sr-only sr-only-focusable
if you need the element to become visible when focused e.g. "skip to main content"
If you want make your website even more accessible I recommend to start here:
Why?
According to the World Health Organization, 285 million people have vision impairments. So making a website accessible is important.
IMPORTANT: Avoid treating disabled users differently. Generally speaking try to avoid developing a different content for different groups of users. Instead try to make accessible the existing content so that it simply works out-of-the-box and for all not specifically targeting e.g. screen readers. In other words don't try to reinvent the wheel. Otherwise the resulting accessibility will often be worse than if there was nothing developed at all. We developers should not assume how those users will use our website. So be very careful when you need to develop such solutions. Obviously a "skip link" is a good example of such content if it's made visible when focused. But there many bad examples too. Such would be hiding from a screen reader a "zoom" button on the map assuming that it has no relevance to blind users. But surprisingly, a zoom function indeed is used among blind users! They like to download images like many other users do (even in high resolution), for sending them to somebody else or for using them in some other context. Source - Read more @ADG: Bad ARIA practices
I suggest using JavaScript's Array method filter()
to identify an element by value. It filters data by using a "function to test each element of the array. Return true to keep the element, false otherwise.."
The following function filters the data, returning data for which the callback returns true
, i.e. where data.code
equals the requested country code.
function getCountryByCode(code) {
return data.filter(
function(data){ return data.code == code }
);
}
var found = getCountryByCode('DZ');
See the demonstration below:
var data = [{_x000D_
"name": "Afghanistan",_x000D_
"code": "AF"_x000D_
}, {_x000D_
"name": "Åland Islands",_x000D_
"code": "AX"_x000D_
}, {_x000D_
"name": "Albania",_x000D_
"code": "AL"_x000D_
}, {_x000D_
"name": "Algeria",_x000D_
"code": "DZ"_x000D_
}];_x000D_
_x000D_
_x000D_
function getCountryByCode(code) {_x000D_
return data.filter(_x000D_
function(data) {_x000D_
return data.code == code_x000D_
}_x000D_
);_x000D_
}_x000D_
_x000D_
var found = getCountryByCode('DZ');_x000D_
_x000D_
document.getElementById('output').innerHTML = found[0].name;
_x000D_
<div id="output"></div>
_x000D_
A combination of TRANSCRIPT_MODE_ALWAYS_SCROLL and setSelection made it work for me
ChatAdapter adapter = new ChatAdapter(this);
ListView lv = (ListView) findViewById(R.id.chatList);
lv.setTranscriptMode(AbsListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
lv.setAdapter(adapter);
adapter.registerDataSetObserver(new DataSetObserver() {
@Override
public void onChanged() {
super.onChanged();
lv.setSelection(adapter.getCount() - 1);
}
});
NONE of these answers work for situations where the value name contains spaces, dots, or other characters that are reserved in PowerShell. In that case you have to wrap the name in double quotes as per http://blog.danskingdom.com/accessing-powershell-variables-with-periods-in-their-name/ - for example:
PS> Get-ItemProperty Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7
14.0 : C:\Program Files (x86)\Microsoft Visual Studio 14.0\
12.0 : C:\Program Files (x86)\Microsoft Visual Studio 12.0\
11.0 : C:\Program Files (x86)\Microsoft Visual Studio 11.0\
15.0 : C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\V
S7
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS
PSChildName : VS7
PSProvider : Microsoft.PowerShell.Core\Registry
If you want to access any of the 14.0, 12.0, 11.0, 15.0 values, the solution from the accepted answer will not work - you will get no output:
PS> (Get-ItemProperty Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7 -Name 15.0).15.0
PS>
What does work is quoting the value name, which you should probably be doing anyway for safety:
PS> (Get-ItemProperty "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7" -Name "15.0")."15.0"
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\
PS>
Thus, the accepted answer should be modified as such:
PS> $key = "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7"
PS> $value = "15.0"
PS> (Get-ItemProperty -Path $key -Name $value).$value
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\
PS>
This works in PowerShell 2.0 through 5.0 (although you should probably be using Get-ItemPropertyValue
in v5).
Yes, you can!
Or if not those terms exactly, then at least the next best thing. In 2020 this is now very straightforward using the CSS math functions: min(), max(), and clamp().
A min
calculation picks the smallest from a comma separated list of values (of any length). This can be used to define a max-padding or max-margin rule:
padding-right: min(50px, 5%);
A max
calculation similarly picks the largest from a comma separated list of values (of any length). This can be used to define a min-padding or min-margin rule:
padding-right: max(15px, 5%);
A clamp
takes three values; the minimum, preferred, and maximum values, in that order.
padding-right: clamp(15px, 5%, 50px);
MDN specifies that clamp is actually just shorthand for:
max(MINIMUM, min(PREFERRED, MAXIMUM))
Here is a clamp
being used to contain a 25vw
margin between the values 100px
and 200px
:
* {
padding: 0;
margin: 0;
box-sizing: border-box;
}
.container {
width: 100vw;
border: 2px dashed red;
}
.margin {
width: auto;
min-width: min-content;
background-color: lightblue;
padding: 10px;
margin-right: clamp(100px, 25vw, 200px);
}
_x000D_
<div class="container">
<div class="margin">
The margin-right on this div uses 25vw as its preferred value,
100px as its minimum, and 200px as its maximum.
</div>
</div>
_x000D_
The math functions can be used in all sorts of different scenarios, even potentially obscure ones like scaling font-size
- they are not just for controlling margin and padding. Check out the full list of use cases at the MDN links at the top of this post.
Here is the caniuse list of browser support. Coverage is generally very good, including almost all modern browsers - with the exception, it appears, of some secondary mobile browsers although have not tested this myself.
Keep dump/backup of all databases.This is not 100% reliable process. Manual backup: Go to datadir path (see in my.ini file) and copy all databases.sql files from data folder
This error will be thrown when unexpectedly MySql service is stopped or disabled and not able to restart in the Services.
First try restart PC and MySql Service couple of times ,if still getting same error then follow the steps.
Keep open the following wizards and folders:
C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin
C:\Program Files (x86)\MySQL\MySQL Server 5.5
Services list ->select MySql Service.
Then select remove instance and click on next to remove non-working MySql service instance. See in the Service list (refresh F5) where MySql service should not be found.
#Path to installation directory
basedir="C:/Program Files (x86)/MySQL/MySQL Server 5.5/"
#Path to data directory
datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/"
Choose data dir Go to "C:/ProgramData/MySQL/MySQL Server 5.5/Data/" It contains all tables data and log info, ib data, user.err,user.pid . Delete
(why because to create new MySql instance or when reconfiguring MySql service by clicking on MySqlInstanceConfig.exe and selecting default configure, after enter choosing password and clicking on execute the wizard will try to create these log files or will try to append the text again to these log files and other files which will make the setup wizard as unresponding and finally end up with configuration not done).
Delete the selected files my.ini and and other .bak format files which cause for the instance config.exe un-responding.
I was stuck in same problem for many hours. I tried everything found on internet.
At last, I figured out a surprising solution : I had missed \SQLEXPRESS
part of the Server name: MY-COMPUTER-NAME\SQLEXPRESS
I hope this helps someone who is stuck in similar kind of problem.
My initial guess without knowing the data would be that the UserNameToVerify is not a multiple of 4 in length. Check out the FromBase64String on msdn.
// Ok
byte[] b1 = Convert.FromBase64String("CoolDude");
// Exception
byte[] b2 = Convert.FromBase64String("MyMan");

One-liner.
i.fa.fa-chevron-right.collapse.in { transform: rotate(180deg); }
In this example it's being used to group collapsible table rows. The only thing you need to do is add the target class name (my-collapse-name) to your icon:
<tr data-toggle="collapse" data-target=".my-collapse-name">
<th><i class="fa fa-chevron-right my-collapse-name"></span></th>
<th>Master Row - Title</th>
</tr>
<tr class="collapse my-collapse-name">
<td></td>
<td>Detail Row - Content</td>
</tr>
You could accomplish the same with Bootstrap's native caret class by using <span class='caret my-collapse-name'></span>
and span.caret.collapse.in { transform: rotate(90deg); }
The answer above did not work for me (python 3.6, Anaconda, pandas 0.20.3). It worked with
conda install -c anaconda pandas
Unfortunately I do not know how to help with Eclipse.
select into
is used in pl/sql to set a variable to field values. Instead, use
create table new_table as select * from old_table
You can also do this by passing function with onclick event
<a onclick="getColor(this);" color="red">
<script type="text/javascript">
function getColor(el)
{
color = $(el).attr('color');
alert(color);
}
</script>
Yes, you're right. With the css()
method you can retrieve the desired css value stored in the DOM. You can read more about this at: http://api.jquery.com/css/
But if you want to get its position you can check offset() and position() methods to get it's position.
Never fails, once I post the question to SO, I get some enlightening "aha" moment and figure it out. The solution:
.container {_x000D_
border: 1px solid #DDDDDD;_x000D_
width: 200px;_x000D_
height: 200px;_x000D_
position: relative;_x000D_
}_x000D_
.tag {_x000D_
float: left;_x000D_
position: absolute;_x000D_
left: 0px;_x000D_
top: 0px;_x000D_
z-index: 1000;_x000D_
background-color: #92AD40;_x000D_
padding: 5px;_x000D_
color: #FFFFFF;_x000D_
font-weight: bold;_x000D_
}
_x000D_
<div class="container">_x000D_
<div class="tag">Featured</div>_x000D_
<img src="http://www.placehold.it/200x200">_x000D_
</div>
_x000D_
The key is the container has to be positioned relative and the tag positioned absolute.
find /root/directory/to/search -name 'filename.*'
# Directory is optional (defaults to cwd)
Standard UNIX globbing is supported. See man find
for more information.
If you're using Vim, you can use:
:e **/filename.cpp
Or :tabn
or any Vim command which accepts a filename.
