(1) Is it possible to pass a JSON object to the url like in Ex.2?
No, because http://localhost:8080/api/v1/mno/objectKey/{"id":1, "name":"Saif"}
is not a valid URL.
If you want to do it the RESTful way, use http://localhost:8080/api/v1/mno/objectKey/1/Saif
, and defined your method like this:
@RequestMapping(path = "/mno/objectKey/{id}/{name}", method = RequestMethod.GET)
public Book getBook(@PathVariable int id, @PathVariable String name) {
// code here
}
(2) How can we pass and parse the parameters in Ex.1?
Just add two request parameters, and give the correct path.
@RequestMapping(path = "/mno/objectKey", method = RequestMethod.GET)
public Book getBook(@RequestParam int id, @RequestParam String name) {
// code here
}
UPDATE (from comment)
What if we have a complicated parameter structure ?
"A": [ { "B": 37181, "timestamp": 1160100436, "categories": [ { "categoryID": 2653, "timestamp": 1158555774 }, { "categoryID": 4453, "timestamp": 1158555774 } ] } ]
Send that as a POST
with the JSON data in the request body, not in the URL, and specify a content type of application/json
.
@RequestMapping(path = "/mno/objectKey", method = RequestMethod.POST, consumes = "application/json")
public Book getBook(@RequestBody ObjectKey objectKey) {
// code here
}
I deactivated my "Arno's Iptables Firewall" for testing, and then the messages are gone
You should add next permission:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
And then here is usages in code:
val externalFilesDir = context.getExternalFilesDir(DIRECTORY_DOWNLOADS)
First we need to check if we have enabled mod_headers.c and mod_expires.c.
sudo apache2 -l
If we don't have it, we need to enable them
sudo a2enmod headers
Then we need to restart apache
sudo apache2 restart
At last, add the rules on .htaccess (seen on other answers), for example

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.
The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.
If you're concerned about server performance then look at capping the number of running sox processes. If the cap has been hit you can always cache the request and inform the user when it's finished in whichever way suits your application.
Alternatively, have the n worker scripts on other machines that pull requests from the db and call sox, and then push the resulting output file to where it needs to be.
Use a selector that will select all the rows and take the length.
var rowCount = $('#myTable tr').length;
Note: this approach also counts all trs of every nested table!

There's a much easier way than recompiling PHP. Just yum install the required mbstring library:
Example: How to install PHP mbstring on CentOS 6.2
yum --enablerepo=remi install php-mbstring
Oh, and don't forget to restart apache afterward.
I was having this problem as well but following Farhan's lead of using setContentView()
I did just that. using setContentView()
by itself was not enough however. I found that I had to repopulate all of my views with information. To fix this I just pulled all of that code out to another method (I called it build) and in my onCreate
method I just call that build. Now whenever my event occurs that I want my activity to "refresh" I just call build, give it the new information (which I pass in as parameters to build) and I have a refreshed activity.
The function you need is CInt
.
ie CInt(PrinterLabel)
See Type Conversion Functions (Visual Basic) on MSDN
Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!
If you are compiling linux kernel. For example, if you want to disable the warning that is "unused-but-set-variable" been treated as error. You can add a statement:
KBUILD_CFLAGS += $(call cc-option,-Wno-error=unused-but-set-variable,)
in your Makefile
You may not have permission to dba_sequences. So you can always just do:
select * from user_sequences;
Using vh on mobile devices is not going to work with 100vh, due to their design choices using the entire height of the device not including any address bars etc.
If you are looking for a layout including div heights proportionate to the true view height I use the following pure css solution:
:root {
--devHeight: 86vh; //*This value changes
}
.div{
height: calc(var(--devHeight)*0.10); //change multiplier to suit required height
}
You have two options for setting the viewport height, manually set the --devHeight to a height that works (but you will need to enter this value for each type of device you are coding for)
or
Use javascript to get the window height and then update --devheight on loading and refreshing the viewport (however this does require using javascript and is not a pure css solution)
Once you obtain your correct view height you can create multiple divs at an exact percentage of total viewport height by simply changing the multiplier in each div you assign the height to.
0.10 = 10% of view height 0.57 = 57% of view height
Hope this might help someone ;)
You must put your mathematical expressions inside $(( )).
One-liner:
for i in {1..600}; do wget http://example.com/search/link$(($i % 5)); done;
Multiple lines:

wget http://example.com/search/link$(($i % 5))
done

In my opinion best way is 1) place the CSS file in the header part in between head tag reason is first page show the view for that css require 2)and all js file should place before the body closing tag. reason is after all component display js can apply
import sys
print(sys.argv)
More specifically, if you run python example.py one two three
:
>>> import sys
>>> print(sys.argv)
['example.py', 'one', 'two', 'three']
I experience the same thing and this is what I do.
First my installation of
pip install -r requirements.txt
is not on my active environment. So I did is activate my environment then run again the

As noted in an issue in the Roslyn project on GitHub, a solution (that worked for me) is to simply unload and reload the project in Visual Studio.
The "bin\roslyn" folder wasn't created on build or rebuild until I reloaded the project.
As ibram stated, add the manifest thru solution explorer:
This creates a default manifest. Now, edit the manifest.

I followed BEN and Thanks and Lot for the Answer,So I used his idea to get my solution, I am posting the same hence if some one else has similar requirement, then you also can use my solution as well, My requirement was something like I want to get the sum of entire data from the first row to the last row, and I was generating the spreadsheet programmatically so don't and can't hard code the row names in sum as the data is always dynamic and number of rows are never constant. My formula was something like as follows.
=SUM(B1:INDIRECT("B"&ROW()-4))
It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.

I'm a PHP developer and to be able to work on my development environment with a certificate, I was able to do the same by finding the real SSL HTTPS/HTTP Certificate and deleting it.
The steps are :
You can find more information at : http://classically.me/blogs/how-clear-hsts-settings-major-browsers
Although this solution is not the best, Chrome currently does not have any good solution for the moment. I have escalated this situation with their support team to help improve user experience.
Edit : you have to repeat the steps every time you will go on the production site.
If you want to remove only leading and trailing whitespace (like PHP's trim) you can use .strip
, but if you want to remove all whitespace, you can use .gsub(/\s+/, "")
instead .
To expand on Pavlo's answer https://stackoverflow.com/a/34063808/1069914, you can have multiple child items justify-content: flex-start
in their behavior but have the last item justify-content: flex-end
.container {

border: solid 10px skyblue;
display: flex;
justify-content: flex-end;
}
.container > *:not(:last-child) {
margin-right: 0;
margin-left: 0;
}
/* set the second to last-child */
.container > :nth-last-child(2) {
margin-right: auto;

Since Powershell 3.0 (shipped with Windows 8, available for Windows 7 and windows Server 2008 but not Windows Vista ) you can use the built-in convertto-json commandlet:

PS E:\> $topicsjson.Length
11909
PS E:\> $topicsjson.getType()

right:0;
}
position: absolute; top:0; right:0; do the work here! :) Also remove the floating!
clock()
returns the number of clock ticks since your program started. There is a related constant, CLOCKS_PER_SEC
, which tells you how many clock ticks occur in one second. Thus, you can test any operation like this:
clock_t startTime = clock();
doSomeOperation();
clock_t endTime = clock();
clock_t clockTicksTaken = endTime - startTime;
double timeInSeconds = clockTicksTaken / (double) CLOCKS_PER_SEC;
An alternative General Plan, which I'm only adding as an independent Answer because the blasted "comment on an answer" won't take newlines without posting the entire edit, even though it isn't finished yet.
UPDATE table A
JOIN table B ON {join fields}
JOIN table C ON {join fields}
JOIN {as many tables as you need}
SET A.column = {expression}
Example:
UPDATE person P
JOIN address A ON P.home_address_id = A.id
JOIN city C ON A.city_id = C.id
SET P.home_zip = C.zipcode;
For my fellow Swift users, here is the code you will need:
let imageName = "un-child-rights.jpg"
let image = UIImage(named: imageName)
cell.imageView!.image = image
After much further research, i managed to find a solution.
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
});
function placeMarker(location) {
var marker = new google.maps.Marker({
position: location,
map: map
});
}
If you don't care about formatting and you just need some quick date, you can use this:
import time
print(time.ctime())
Running this:
sqllocaldb create "v12.0"
From cmd prompt solved this for me...
Starting from a byte array you can use the binary package to do the conversions.
For example if you want to read ints :
buf := bytes.NewBuffer(b) // b is []byte
myfirstint, err := binary.ReadVarint(buf)
anotherint, err := binary.ReadVarint(buf)
The same package allows the reading of unsigned int or floats, with the desired byte orders, using the general Read function.
You can use :
const intersection = array1.filter(element => array2.includes(element));
A TextinputLayout
is not a view, but a Layout
, as very nicely described by Dimitrios Tsigouris in his blog post here. Therefore, you don't need a Style
, which is for Views
only, but use a Theme
. Following the blog post, I ended up with the following solution:
Start in your styles.xml
with
<style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
<!-- reference our hint & error styles -->
<item name="android:textColor">@color/your_colour_here</item>
<item name="android:textColorHint">@color/your_colour_here</item>
<item name="colorControlNormal">@color/your_colour_here</item>
<item name="colorControlActivated">@color/your_colour_here</item>
<item name="colorControlHighlight">@color/your_colour_here</item>
</style>
And in your layout add
<com.google.android.material.textfield.TextInputLayout
android:theme="@style/TextInputLayoutAppearance"
...
The new way to do with c++20 is using format.
#include <format>
auto var = std::format("sometext {} sometext {}", somevar, somevar);
DIR=your_path
find $DIR | sed 's:""$DIR""::'
'sed' will erase 'your_path' from all 'find' results. And you recieve relative to 'DIR' path.
Check if your server is full first, thats a common reason (can't create the PID file because you have no space). Run this to check your disk usage..
df -h
If you get something like this, you are full..
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 40G 40G 6.3M 100% /
In that case, you need to start looking for what to delete to make room, or add an additional drive to your server.
I'm writing an answer to increase visibility to the actual syntax that solves the problem. Unfortunately, what someone might see as trivial can become a very significant headache to someone looking for a simple answer to a reasonable question.
Put the following into the file "Makefile".
MY_VAR := $(shell python -c 'import sys; print int(sys.version_info >= (2,5))')
all:
@echo MY_VAR IS $(MY_VAR)
The behavior you would like to see is the following (assuming you have recent python installed).
make
MY_VAR IS 1
If you copy and paste the above text into the Makefile, will you get this? Probably not. You will probably get an error like what is reported here:
makefile:4: *** missing separator. Stop
Why: Because although I personally used a genuine tab, Stack Overflow (attempting to be helpful) converts my tab into a number of spaces. You, frustrated internet citizen, now copy this, thinking that you now have the same text that I used. The make command, now reads the spaces and finds that the "all" command is incorrectly formatted. So copy the above text, paste it, and then convert the whitespace before "@echo" to a tab, and this example should, at last, hopefully, work for you.
I had exactly the same problem. Just one more working modification of the solution given by Denis (the type must be specified):
SELECT ARRAY(
SELECT column_name::text
FROM information_schema.columns
WHERE table_name='aean'
)
@echo off
::Ask
echo Your Source Path:
set INPUT1=
set /P INPUT1=Type input: %=%
echo Your Destination Path:
set INPUT2=
set /P INPUT2=Type input: %=%
xcopy %INPUT1% %INPUT2% /y /s
Here are some ways to get total records count while doing MongoDB Aggregation:
$count
:db.collection.aggregate([
// Other stages here
{ $count: "Total" }
])
For getting 1000 records this takes on average 2 ms and is the fastest way.
.toArray()
:db.collection.aggregate([...]).toArray().length
For getting 1000 records this takes on average 18 ms.
.itcount()
:db.collection.aggregate([...]).itcount()
For getting 1000 records this takes on average 14 ms.
Make sure to use the !important attribute. This dramatically increases the likelihood your styles are retained when printed.
#example1 {
background:url(image.png) no-repeat !important;
}
#example2 {
background-color: #123456 !important;
}
You need an event handler which will fire when the button is clicked. Here is a quick way -
var button = new Button();
button.Text = "my button";
this.Controls.Add(button);
button.Click += (sender, args) =>
{
MessageBox.Show("Some stuff");
Close();
};
But it would be better to understand a bit more about buttons, events, etc.
If you use the visual studio UI to create a button and double click the button in design mode, this will create your event and hook it up for you. You can then go to the designer code (the default will be Form1.Designer.cs) where you will find the event:
this.button1.Click += new System.EventHandler(this.button1_Click);
You will also see a LOT of other information setup for the button, such as location, etc. - which will help you create one the way you want and will improve your understanding of creating UI elements. E.g. a default button gives this on my 2012 machine:
this.button1.Location = new System.Drawing.Point(128, 214);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 1;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
As for closing the Form, it is as easy as putting Close(); within your event handler:
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("some text");
Close();
}
Use [^A-Za-z0-9]
.
Note: removed the space since that is not typically considered alphanumeric.
Use the vector
constructor that takes two iterators, note that pointers are valid iterators, and use the implicit conversion from arrays to pointers:
int x[3] = {1, 2, 3};
std::vector<int> v(x, x + sizeof x / sizeof x[0]);
test(v);
or
test(std::vector<int>(x, x + sizeof x / sizeof x[0]));
where sizeof x / sizeof x[0]
is obviously 3
in this context; it's the generic way of getting the number of elements in an array. Note that x + sizeof x / sizeof x[0]
points one element beyond the last element.
It isn't that tough to construct a mapping:
1 2 3 4 5 use this mapping if (a,b) != (b,a) 1 0 1 3 6 10 2 2 4 7 11 16 3 5 8 12 17 23 4 9 13 18 24 31 5 14 19 25 32 40 1 2 3 4 5 use this mapping if (a,b) == (b,a) (mirror) 1 0 1 2 4 6 2 1 3 5 7 10 3 2 5 8 11 14 4 4 8 11 15 19 5 6 10 14 19 24 0 1 -1 2 -2 use this if you need negative/positive 0 0 1 2 4 6 1 1 3 5 7 10 -1 2 5 8 11 14 2 4 8 11 15 19 -2 6 10 14 19 24
Figuring out how to get the value for an arbitrary a,b is a little more difficult.
We can implement by 3 Methods:
Note:
"automatic-scroll" => The particular element
"scrollable-div" => The scrollable area div
Method 1:
document.querySelector('.automatic-scroll').scrollIntoView({
behavior: 'smooth'
});
Method 2:
location.href = "#automatic-scroll";
Method 3:
$('#scrollable-div').animate({
scrollTop: $('#automatic-scroll').offset().top - $('#scrollable-div').offset().top +
$('#scrollable-div').scrollTop()
})
Important notice: method 1 & method 2 will be useful if the scrollable area height is "auto". Method 3 is useful if we using the scrollable area height like "calc(100vh - 200px)".
You could use the [DataType]
attribute on your view model like this:
public class MyViewModel
{
[DataType(DataType.MultilineText)]
public string Text { get; set; }
}
and then you could have a controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyViewModel());
}
}
and a view which does what you want:
@model AppName.Models.MyViewModel
@using (Html.BeginForm())
{
@Html.EditorFor(x => x.Text)
<input type="submit" value="OK" />
}
There is no built-in operator to do it in Go. You need to iterate over the array. You can write your own function to do it, like this:
func stringInSlice(a string, list []string) bool {
for _, b := range list {
if b == a {
return true
}
}
return false
}
If you want to be able to check for membership without iterating over the whole list, you need to use a map instead of an array or slice, like this:
visitedURL := map[string]bool {
"http://www.google.com": true,
"https://paypal.com": true,
}
if visitedURL[thisSite] {
fmt.Println("Already been here.")
}
I somehow achieved this by knowing the status of the soft keyboard on the device. i move the layout to y position when the keyboard is shown and moved back to its original position when not shown. this works fine, followed this guidelines.
This works great if a straight copy is in order. If the situation calls for creating new objects from templates, I usually wrap the template div in a hidden storage div and use jquery's html() in conjunction with clone() applying the following technique:
<style>
#element-storage {
display: none;
top: 0;
right: 0;
position: fixed;
width: 0;
height: 0;
}
</style>
<script>
$("#new-div").append($("#template").clone().html(function(index, oldHTML){
// .. code to modify template, e.g. below:
var newHTML = "";
newHTML = oldHTML.replace("[firstname]", "Tom");
newHTML = newHTML.replace("[lastname]", "Smith");
// newHTML = newHTML.replace(/[Example Replace String]/g, "Replacement"); // regex for global replace
return newHTML;
}));

$("#idofBtn").click(function(){
$('#idofdropdown').empty(); //remove all child nodes
var newOption = $('<option value="1">test</option>');
$('#idofdropdown').append(newOption);
$('#idofdropdown').trigger("chosen:updated");
});
Also, if you do want to do the replacement yourself, the character you need to look for is [ ? ].
But if you're using Eclipse, it will freak out when you type that letter into a [replace] statement telling you it conflicts with Cp1252 - this is an Eclipse bug. To fix it, go to
Window -> Preferences -> General -> Workspace -> Text file encoding,
and select [UTF-8]
Like answered before, you should use:
Object value = field.get(objectInstance);
Another way, which is sometimes prefered, is calling the getter dynamically. example code:
public static Object runGetter(Field field, BaseValidationObject o)
{
// MZ: Find the correct method
for (Method method : o.getMethods())
{
if ((method.getName().startsWith("get")) && (method.getName().length() == (field.getName().length() + 3)))
{
if (method.getName().toLowerCase().endsWith(field.getName().toLowerCase()))
{
// MZ: Method found, run it
try
{
return method.invoke(o);
}
catch (IllegalAccessException e)
{
Logger.fatal("Could not determine method: " + method.getName());
}
catch (InvocationTargetException e)
{
Logger.fatal("Could not determine method: " + method.getName());
}
}
}
}
return null;
}
Also be aware that when your class inherits from another class, you need to recursively determine the Field. for instance, to fetch all Fields of a given class;
for (Class<?> c = someClass; c != null; c = c.getSuperclass())
{
Field[] fields = c.getDeclaredFields();
for (Field classField : fields)
{
result.add(classField);
}
}

You can also do ORDER BY TITLE COLLATE NOCASE
.
Edit: If you need to specify ASC
or DESC
, add this after NOCASE
like
ORDER BY TITLE COLLATE NOCASE ASC
or
ORDER BY TITLE COLLATE NOCASE DESC
Try this:

});
if (unique) cleaned.push(itm);
});
return cleaned;
}
var standardsList = arrUnique(standardsList);
This will return

simplify2array
is a base function that is fairly intuitive. However, since R's default is to fill in data by columns first, you will need to transpose the output. (sapply

Line Input works fine for small files. However, when file sizes reach around 90k, Line Input jumps all over the place and reads data in the wrong order from the source file. I tested it with different filesizes:
49k = ok
60k = ok
78k = ok
85k = ok
93k = error
101k = error
127k = error
156k = error

Let me know if you find any issue.
if you are using any mobile suit like mobogenie or something that might also will make this issue. try killing that too from the task manager.
Note : i faced the same issue, tried the above solution. That didn't work, finally found out this solution.May useful for someone else!..
There's no need to group in that subquery... a where clause would suffice:
SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
FROM tblpm WHERE control_number=n.control_number)
Also, do you have an index on the 'date_updated' column? That would certainly help.
I had the same problem but then realized the arrangement of my icon graphic within the square allowed (512 x 512 in my case) was not maximized. So I rotated the image and was able to scale it up to fill the corners better. Then I right clicked on my res
folder in my project in Android Studio, then choose New
then Image Asset
, it took me through a wizard where I got to select my image file to use. Then if you check the box that says "Trim surrounding blank space", it makes sure all edges, that are able, touch the sides of your square. These steps got it much bigger than the original.
If you want to update a single gem to a specific version:
bundle update

OWASP recommends the following,
Whenever possible ensure the cache-control HTTP header is set with no-cache, no-store, must-revalidate, private; and that the pragma HTTP header is set with no-cache.
<IfModule mod_headers.c>
Header set Cache-Control "private, no-cache, no-store, proxy-revalidate, no-transform"
Header set Pragma "no-cache"
</IfModule>
You could also just change the @RequestParam default required status to false so that HTTP response status code 400 is not generated. This will allow you to place the Annotations in any order you feel like.
@RequestParam(required = false)String name
For me it works:
document.getElementById("checkyear").value = "1";
alert(document.getElementById("checkyear").value);
Maybe your JS is not executed and you need to add a function() {} around it all.
The Above answers are good . But I found this method more efficient using above results.
This results in actual script file name not a path.
import sys
import os
file_name = os.path.basename(sys.argv[0])
Instead of setting the @JsonSerialize on each member or getter you can configure a module that use a custome serializer for a certain type:
SimpleModule module = new SimpleModule();
module.addSerializer(BigInteger.class, new ToStringSerializer());
objectMapper.registerModule(module);
In the above example, I used the to string serializer to serialize BigIntegers (since javascript can not handle such numeric values).
In my opinion many of the answers here seem a little bit hacky (e.g. $apply() or $timeout), since messing around with $apply() can lead to unwanted errors.
Usually, when the $location doesn't work it means that something was not implemented the angular way.
In this particular question, the problem seems to be in the non-angular AJAX part. I had a similiar problem, where the redirection using $location should take place after a promise resolved. I would like to illustrate the problem on this example.
The old code:
taskService.createTask(data).then(function(code){
$location.path("task/" + code);
}, function(error){});
Note: taskService.createTask returns a promise.
$q - the angular way to use promises:
let dataPromises = [taskService.createTask(data)];
$q.all(dataPromises).then(function(response) {
let code = response[0];
$location.path("task/" + code);
},
function(error){});
Using $q to resolve the promise solved the redirection problem.

Unless you want the canvas to upscale your image data automatically (that's what James Black's answer talks about, but it won't look pretty), you have to resize it yourself and redraw the image. Centering a canvas
As mentioned in comments, a StringBuilder is probably a faster implementation than using a StringBuffer. As mentioned in the Java docs:
This class provides an API compatible with StringBuffer, but with no guarantee of synchronization. This class is designed for use as a drop-in replacement for StringBuffer in places where the string buffer was being used by a single thread (as is generally the case). Where possible, it is recommended that this class be used in preference to StringBuffer as it will be faster under most implementations.
Usage :
String str = Integer.toString(j);
str = new StringBuilder(str).insert(str.length()-2, ".").toString();
Or if you need synchronization use the StringBuffer with similar usage :
String str = Integer.toString(j);
str = new StringBuffer(str).insert(str.length()-2, ".").toString();

From your question, you are running python2.7 and Cygwin.
Python should be installed for windows, which from your question it seems it is. If "which python" prints out /usr/bin/python , then from the bash prompt you are running the cygwin version.
Set the Python Environmental variables appropriately , for instance in my case:
PY_HOME=C:\opt\Python27
PYTHONPATH=C:\opt\Python27;c:\opt\Python27\Lib
In that case run cygwin setup and uninstall everything python. After that run "which pydoc", if it shows
/usr/bin/pydoc
Replace /usr/bin/pydoc with
#! /bin/bash
/cygdrive/c/WINDOWS/system32/cmd /c %PYTHONHOME%\Scripts\\pydoc.bat
Then add this to $PY_HOME/Scripts/pydoc.bat
rem wrapper for pydoc on Win32
@python c:\opt\Python27\Lib\pydoc.py %*
Now when you type in the cygwin bash prompt you should see:
$ pydoc
pydoc - the Python documentation tool
pydoc.py <name> ...
Show text documentation on something. <name>
may be the name of a Python keyword, topic,
function, module, or package, or a dotted
reference to a class or function within a
module or module in a package.
...
Log in as root or do

Then:
service memcached restart
If that doesn't work, then:
/etc/init.d/memcached restart
It all depends on which Linux distro (or other OS) you're using.
File may be inside a directory, in that case specify the path:
import os
old_file = os.path.join("directory", "a.txt")
new_file = os.path.join("directory", "b.kml")
os.rename(old_file, new_file)
While the documentation recommends using weak
on properties for subviews, since iOS 6 it seems to be fine to use strong
(the default ownership qualifier) instead. That's caused by the change in UIViewController
that views are not unloaded anymore.
That said, I am torn between using
@property (nonatomic, weak) IBOutlet UIButton *button;
and
@property (nonatomic) IBOutlet UIButton *button;
in iOS 6 and after:
Using weak
clearly states that the controller doesn't want ownership of the button.
But omitting weak
doesn't hurt in iOS 6 without view unloading, and is shorter. Some may point out that is also faster, but I have yet to encounter an app that is too slow because of weak
IBOutlet
s.
Not using weak
may be perceived as an error.
Bottom line: Since iOS 6 we can't get this wrong anymore as long as we don't use view unloading. Time to party. ;)
Absolute positioning positions an element relative to its nearest positioned ancestor. So put position: relative
on the container, then for child elements, top
and left
will be relative to the top-left of the container so long as the child elements have position: absolute
. More information is available in the CSS 2.1 specification.
I solved a situation where I needed a template for the element that would handle alternatively a regular URL or a javascript call, where the js function needs a reference to the calling element. In javascript, "this" works as a self reference only in the context of a form element, e.g., a button. I didn't want a button, just the apperance of a regular link.
Examples:
<a onclick="http://blahblah" href="http://blahblah" target="_blank">A regular link</a>
<a onclick="javascript:myFunc($(this));return false" href="javascript:myFunc($(this));" target="_blank">javascript with self reference</a>
The href and onClick attributes have the same values, exept I append "return false" on onClick when it's a javascript call. Having "return false" in the called function did not work.
Basic :
CREATE TABLE table1 (
columnA INTEGER NOT NULL,
columnB INTEGER NOT NULL,
PRIMARY KEY (columnA, columnB)
);
If your columns are foreign keys of other tables (common case) :
CREATE TABLE table1 (
table2_id INTEGER NOT NULL,
table3_id INTEGER NOT NULL,
FOREIGN KEY (table2_id) REFERENCES table2(id),
FOREIGN KEY (table3_id) REFERENCES table3(id),
PRIMARY KEY (table2_id, table3_id)
);
CREATE TABLE table2 (
id INTEGER NOT NULL,
PRIMARY KEY id
);
CREATE TABLE table3 (
id INTEGER NOT NULL,
PRIMARY KEY id
);
This will work with iPad on Safari on iOS 7.1.x from my testing, I'm not sure about iOS 6 though. However, it will not work on Firefox. There is a jQuery plugin which aims to be cross browser compliant called jScrollPane.
Also, there is a duplicate post here on Stack Overflow which has some other details.
This worked for me:
find ./ -type f -exec sed -i '' 's#NEEDLE#REPLACEMENT#' *.php {} \;
After you install the ftp server with sudo apt-get install vsftpd
you will have to configure it. To enable write access you have to edit the /etc/vsftpd.conf
file and uncomment the
#write_enable=YES
line, so it should read
write_enable=YES
Save the file and restart vsftpd
with sudo service vsftpd restart
.
For other configuration options consult this documentation or man vsftpd.conf

The SSA is instituting a new policy the where all previously unused sequences are will be available for use.
Goes into affect June 25, 2011.
Taken from the new FAQ:
What changes will result from randomization?
The SSA will eliminate the geographical significance of the first three digits of the SSN, currently referred to as the area number, by no longer allocating the area numbers for assignment to individuals in specific states. The significance of the highest group number (the fourth and fifth digits of the SSN) for validation purposes will be eliminated. Randomization will also introduce previously unassigned area numbers for assignment excluding area numbers 000, 666 and 900-999. Top
Will SSN randomization assign group number (the fourth and fifth digits of the SSN) 00 or serial number (the last four digits of the SSN) 0000?
SSN randomization will not assign group number 00 or serial number 0000. SSNs containing group number 00 or serial number 0000 will continue to be invalid.
If you are using systemd I just found out that you seem to have to add them to the systemd unit file. This on Ubuntu 16. Putting them into the .profile and .bashrc (even the /etc/profile) resulted in the ENV Vars not being available in the juypter notebooks.
I had to edit:
/lib/systemd/system/jupyer-notebook.service
and put in the variable i wanted to read in the unit file like:
Environment=MYOWN_VAR=theVar
and only then could I read it from within juypter notebook.
Or you could go the regex route:
String date = "10/07/2010";
String newDate = date.replaceAll("(\\d+)/(\\d+)/(\\d+)", "$3/$2/$1");
System.out.println(newDate);
It works both ways too. Of course this won't actually validate your date and will also work for strings like "21432/32423/52352". You can use "(\\d{2})/(\\d{2})/(\\d{4}"
to be more exact in the number of digits in each group, but it will only work from dd/MM/yyyy to yyyy/MM/dd and not the other way around anymore (and still accepts invalid numbers in there like 45). And if you give it something invalid like "blabla" it will just return the same thing back.
(1) == can be be applied for both primitives and object types, but equals() method can be applied for only object types.
(2) == cannot be overridden for content comparison, but equals method can be overridden for content comparison(ex; String class, wrapper classes, collection classes).
(3) == gives incomparable types error when try to apply for heterogeneous types , where as equals method returns false.
You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.
I've just done this in a grunt
project of ours. We needed a newer version of connect, since 2.7.3
. was causing trouble for us. So I created a file named npm-shrinkwrap.json
:
{
"dependencies": {
"grunt-contrib-connect": {
"version": "0.3.0",
"from": "[email protected]",
"dependencies": {
"connect": {
"version": "2.8.1",
"from": "connect@~2.7.3"
}
}
}
}
}
npm
should automatically pick it up while doing the install for the project.
(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)
A simple example for writing multiple data to excel at a time. And also when you want to append data to a sheet on a written excel file (closed excel file).
When it is your first time writing to an excel. (Writing "df1" and "df2" to "1st_sheet" and "2nd_sheet")
import pandas as pd
from openpyxl import load_workbook
df1 = pd.DataFrame([[1],[1]], columns=['a'])
df2 = pd.DataFrame([[2],[2]], columns=['b'])
df3 = pd.DataFrame([[3],[3]], columns=['c'])
excel_dir = "my/excel/dir"
with pd.ExcelWriter(excel_dir, engine='xlsxwriter') as writer:
df1.to_excel(writer, '1st_sheet')
df2.to_excel(writer, '2nd_sheet')
writer.save()
After you close your excel, but you wish to "append" data on the same excel file but another sheet, let's say "df3" to sheet name "3rd_sheet".
book = load_workbook(excel_dir)
with pd.ExcelWriter(excel_dir, engine='openpyxl') as writer:
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
## Your dataframe to append.
df3.to_excel(writer, '3rd_sheet')
writer.save()
Be noted that excel format must not be xls, you may use xlsx one.
You can use the asp:Table in your web form and build it via code:
http://msdn.microsoft.com/en-us/library/7bewx260.aspx
Also, check out asp.net for tutorials and such.
If you do not want to use constructors, and you want to have a special name for the method, try it this:
public enum MyType {
ONE {
public String getDescription() {
return "this is one";
}
},
TWO {
public String getDescription() {
return "this is two";
}
};
public abstract String getDescription();
}
I suspect that this is the quickest solution. There is no need to use variables final.
date = new DateTime(date.year, date.month, date.day, HH, MM, SS);
There are 3 access specifiers
for a class/struct/Union in C++. These access specifiers define how the members of the class can be accessed. Of course, any member of a class is accessible within that class(Inside any member function of that same class). Moving ahead to type of access specifiers, they are:
Public - The members declared as Public are accessible from outside the Class through an object of the class.
Protected - The members declared as Protected are accessible from outside the class BUT only in a class derived from it.
Private - These members are only accessible from within the class. No outside Access is allowed.
An Source Code Example:
class MyClass
{
public:
int a;
protected:
int b;
private:
int c;
};
int main()
{
MyClass obj;
obj.a = 10; //Allowed
obj.b = 20; //Not Allowed, gives compiler error
obj.c = 30; //Not Allowed, gives compiler error
}
Inheritance in C++ can be one of the following types:
Private
Inheritance Public
Inheritance Protected
inheritance Here are the member access rules with respect to each of these:
First and most important rule
Private
members of a class are never accessible from anywhere except the members of the same class.
All
Public
members of the Base Class becomePublic
Members of the derived class &
AllProtected
members of the Base Class becomeProtected
Members of the Derived Class.
i.e. No change in the Access of the members. The access rules we discussed before are further then applied to these members.
Code Example:
Class Base
{
public:
int a;
protected:
int b;
private:
int c;
};
class Derived:public Base
{
void doSomething()
{
a = 10; //Allowed
b = 20; //Allowed
c = 30; //Not Allowed, Compiler Error
}
};
int main()
{
Derived obj;
obj.a = 10; //Allowed
obj.b = 20; //Not Allowed, Compiler Error
obj.c = 30; //Not Allowed, Compiler Error
}
All
Public
members of the Base Class becomePrivate
Members of the Derived class &
AllProtected
members of the Base Class becomePrivate
Members of the Derived Class.
An code Example:
Class Base
{
public:
int a;
protected:
int b;
private:
int c;
};
class Derived:private Base //Not mentioning private is OK because for classes it defaults to private
{
void doSomething()
{
a = 10; //Allowed
b = 20; //Allowed
c = 30; //Not Allowed, Compiler Error
}
};
class Derived2:public Derived
{
void doSomethingMore()
{
a = 10; //Not Allowed, Compiler Error, a is private member of Derived now
b = 20; //Not Allowed, Compiler Error, b is private member of Derived now
c = 30; //Not Allowed, Compiler Error
}
};
int main()
{
Derived obj;
obj.a = 10; //Not Allowed, Compiler Error
obj.b = 20; //Not Allowed, Compiler Error
obj.c = 30; //Not Allowed, Compiler Error
}
All
Public
members of the Base Class becomeProtected
Members of the derived class &
AllProtected
members of the Base Class becomeProtected
Members of the Derived Class.
A Code Example:
Class Base
{
public:
int a;
protected:
int b;
private:
int c;
};
class Derived:protected Base
{
void doSomething()
{
a = 10; //Allowed
b = 20; //Allowed
c = 30; //Not Allowed, Compiler Error
}
};
class Derived2:public Derived
{
void doSomethingMore()
{
a = 10; //Allowed, a is protected member inside Derived & Derived2 is public derivation from Derived, a is now protected member of Derived2
b = 20; //Allowed, b is protected member inside Derived & Derived2 is public derivation from Derived, b is now protected member of Derived2
c = 30; //Not Allowed, Compiler Error
}
};
int main()
{
Derived obj;
obj.a = 10; //Not Allowed, Compiler Error
obj.b = 20; //Not Allowed, Compiler Error
obj.c = 30; //Not Allowed, Compiler Error
}
Remember the same access rules apply to the classes and members down the inheritance hierarchy.
- Access Specification is per-Class not per-Object
Note that the access specification C++ work on per-Class basis and not per-object basis.
A good example of this is that in a copy constructor or Copy Assignment operator function, all the members of the object being passed can be accessed.
- A Derived class can only access members of its own Base class
Consider the following code example:
class Myclass
{
protected:
int x;
};
class derived : public Myclass
{
public:
void f( Myclass& obj )
{
obj.x = 5;
}
};
int main()
{
return 0;
}
It gives an compilation error:
prog.cpp:4: error: ‘int Myclass::x’ is protected
Because the derived class can only access members of its own Base Class. Note that the object obj
being passed here is no way related to the derived
class function in which it is being accessed, it is an altogether different object and hence derived
member function cannot access its members.
friend
? How does friend
affect access specification rules?You can declare a function or class as friend
of another class. When you do so the access specification rules do not apply to the friend
ed class/function. The class or function can access all the members of that particular class.
So do
friend
s break Encapsulation?
No they don't, On the contrary they enhance Encapsulation!
friend
ship is used to indicate a intentional strong coupling between two entities.
If there exists a special relationship between two entities such that one needs access to others private
or protected
members but You do not want everyone to have access by using the public
access specifier then you should use friend
ship.
To put it in very practical terms:
If you use a const in dll A and dll B references that const, the value of that const will be compiled into dll B. If you redeploy dll A with a new value for that const, dll B will still be using the original value.
If you use a readonly in dll A and dll B references that readonly, that readonly will always be looked up at runtime. This means if you redeploy dll A with a new value for that readonly, dll B will use that new value.
They can be considered as equivalent. The limits in size are the same:
There is also the DBCLOBs, for double byte characters.
References:
You need to use the full property name for each:
background-color: #6DB3F2;
background-image: url('images/checked.png');
Or, you can use the background shorthand and specify it all in one line:
background: url('images/checked.png'), #6DB3F2;
Mine was a name spacing issue. I had two files with the same name. Just renamed them and it resolved.
Always gotta check the 'stupid me' box first before looking elsewhere. : )
One more point to add on to this thread.
If you add an underscore in your .css file name, then it wouldn't work.
How about importing the username and password from a file external to the script? That way even if someone got hold of the script, they wouldn't automatically get the password.
As of C# 7.0, you can use the is keyword to do this :
With those class defined :
class Base { /* Define base class */ }
class Derived : Base { /* Define derived class */ }
You can then do somehting like :
void Funtion(Base b)
{
if (b is Derived d)
{
/* Do something with d which is now a variable of type Derived */
}
}
Which would be equivalent to :
void Funtion(Base b)
{
Defined d;
if (b is Derived)
{
d = (Defined)b;
/* Do something with d */
}
}
You could now call :
Function(new Derived()); // Will execute code defined in if
As well as
Function(new Base()); // Won't execute code defined in if
That way you can be sure that your downcast will be valid and won't throw an exception !
I finally found out how to do this! Basically you need to run adb shell
first and then while you're in the shell run su
, which will switch the shell to run as root!
$: adb shell
$: su
The one problem I still have is that sqlite3 is not installed so the command is not recognized.
A standard LEFT JOIN could resolve the problem and, if the fields on join are indexed,
should also be faster
SELECT *
FROM Table1 as t1 LEFT JOIN Table2 as t2
ON t1.FirstName = t2.FirstName AND t1.LastName=t2.LastName
WHERE t2.BirthDate Is Null

First of all, there're two kinds of keystores.
Individual and General
The application will use the one indicated in the startup or the default of the system.
It will be a different folder if JRE or JDK is running, or if you check the personal or the "global" one.
They are encrypted too
In short, the path will be like:
$JAVA_HOME/lib/security/cacerts
for the "general one", who has all the CA for the Authorities and is quite important.

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??
if i am then please try this,
import csv
with open(r"C:\\test.csv", "wb") as csv_file:
writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
writer.writerow(["a","b"])
you have to set the delimiter = ","
If you just want to make some modification to files or inspect processes, here's one another solution you probably want.
You could run the following command to execute a new process from the existing container:
sudo docker exec -ti [CONTAINER-ID] bash
will start a new process with bash shell, and you could escape from it by Ctrl+C directly, it won't affect the original process.

Since you're on an embedded platform, it's quite possible that you don't have the full range of capabilities from the printf()
-style functions.
Assuming you have floats at all (still not necessarily a given for embedded stuff), you can emulate it with something like:
char str[100];
float adc_read = 678.0123;
char *tmpSign = (adc_read < 0) ? "-" : "";
float tmpVal = (adc_read < 0) ? -adc_read : adc_read;
int tmpInt1 = tmpVal; // Get the integer (678).
float tmpFrac = tmpVal - tmpInt1; // Get fraction (0.0123).
int tmpInt2 = trunc(tmpFrac * 10000); // Turn into integer (123).
// Print as parts, note that you need 0-padding for fractional bit.
sprintf (str, "adc_read = %s%d.%04d\n", tmpSign, tmpInt1, tmpInt2);
You'll need to restrict how many characters come after the decimal based on the sizes of your integers. For example, with a 16-bit signed integer, you're limited to four digits (9,999 is the largest power-of-ten-minus-one that can be represented).
However, there are ways to handle this by further processing the fractional part, shifting it by four decimal digits each time (and using/subtracting the integer part) until you have the precision you desire.
Update:
One final point you mentioned that you were using avr-gcc
in a response to one of the other answers. I found the following web page that seems to describe what you need to do to use %f
in your printf()
statements here.
As I originally suspected, you need to do some extra legwork to get floating point support. This is because embedded stuff rarely needs floating point (at least none of the stuff I've ever done). It involves setting extra parameters in your makefile and linking with extra libraries.
However, that's likely to increase your code size quite a bit due to the need to handle general output formats. If you can restrict your float outputs to 4 decimal places or less, I'd suggest turning my code into a function and just using that - it's likely to take up far less room.
In case that link ever disappears, what you have to do is ensure that your gcc command has "-Wl,-u,vfprintf -lprintf_flt -lm
". This translates to:
printf()
library for searching.SQL Server databases use two files - an MDF file, known as the primary database file, which contains the schema and data, and a LDF file, which contains the logs. See wikipedia. A database may also use secondary database file, which normally uses a .ndf extension.
As John S. indicates, these file extensions are purely convention - you can use whatever you want, although I can't think of a good reason to do that.
More info on MSDN here and in Beginning SQL Server 2005 Administation (Google Books) here.
If you want to plot a single line connecting all the points in the list
plt.plot(li[:])
plt.show()
This will plot a line connecting all the pairs in the list as points on a Cartesian plane from the starting of the list to the end. I hope that this is what you wanted.
This worked for me:
@JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSZ", shape = JsonFormat.Shape.STRING)
private LocalDateTime startDate;
You have duplicate style attributes on each element.
style="opacity:0.8"
This certainly does not display on Firefox for me because of this error. If it displays on Chrome, best raise a Chrome bug.
in C, unsigned
is a shortcut for unsigned int
.
You have the same for long
that is a shortcut for long int
And it is also possible to declare a unsigned long
(it will be a unsigned long int
).
This is in the ANSI standard
"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.
GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html
Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:
SELECT

p1.cName,
p1.cKurzBeschreibung,
p1.dLetzteAktualisierung,
p1.dErstellt,
p1.cSeo,
p2.kartikelpict,
p2.nNr,
p2.cPfad
FROM
tartikel AS p1 INNER JOIN tartikelpict AS p2
ON p1.kArtikel = p2.kArtikel
WHERE
DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
AND p2.nNr = 1
ORDER BY
p1.kArtikel DESC
LIMIT

Click on new file in github repo online.
Then write file name as myfolder/myfilename
then give file contents and commit. Then file will be created within that new folder.
I use this function in all my js projects
You call it: hideAndResetModals("#IdModalDialog")
You define if:
function hideAndResetModals(modalID)
{
$(modalID).modal('hide');
clearValidation(modalID); //You implement it if you need it. If not, you can remote this line
$(modalID).on('hidden.bs.modal', function ()
{
$(modalID).find('form').trigger('reset');
});
}
I found using while IFS='=' read -r
to be a bit slow (I don't know why, maybe someone could briefly explain in a comment or point to a SO answer?). I also found @Nicolai answer very neat as a one-liner, but very inefficient as it will scan the entire properties file over and over again for every single call of prop
.
I found a solution that answers the question, performs well and it is a one-liner (bit verbose line though).
The solution does sourcing but massages the contents before sourcing:
#!/usr/bin/env bash
source <(grep -v '^ *#' ./app.properties | grep '[^ ] *=' | awk '{split($0,a,"="); print gensub(/\./, "_", "g", a[1]) "=" a[2]}')
echo $db_uat_user
Explanation:
grep -v '^ *#'
: discard comment lines
grep '[^ ] *='
: discards lines without =
split($0,a,"=")
: splits line at =
and stores into array a
, i.e. a[1] is the key, a[2] is the value
gensub(/\./, "_", "g", a[1])
: replaces .
with _
print gensub... "=" a[2]}
concatenates the result of gensub
above with =
and value.
Edit: As others pointed out, there are some incompatibilities issues (awk) and also it does not validate the contents to see if every line of the property file is actually a kv pair. But the goal here is to show the general idea for a solution that is both fast and clean. Sourcing seems to be the way to go as it loads the properties once that can be used multiple times.
Locally I run visual studio with admin rights and the error was gone.
If you get this error in task scheduler you have to check the option run with high privileges.
This worked for me:
table {border-collapse: collapse}
table th, table td {padding: 0}
You set the size on initialization:
fig2 = matplotlib.pyplot.figure(figsize=(8.0, 5.0)) # in inches!
Edit:
If the problem is with x-axis ticks - You can set them "manually":
fig2.add_subplot(111).set_xticks(arange(1,3,0.5)) # You can actually compute the interval You need - and substitute here
And so on with other aspects of Your plot. You can configure it all. Here's an example:
from numpy import arange
import matplotlib
# import matplotlib as mpl
import matplotlib.pyplot
# import matplotlib.pyplot as plt
x1 = [1,2,3]
y1 = [4,5,6]
x2 = [1,2,3]
y2 = [5,5,5]
# initialization
fig2 = matplotlib.pyplot.figure(figsize=(8.0, 5.0)) # The size of the figure is specified as (width, height) in inches
# lines:
l1 = fig2.add_subplot(111).plot(x1,y1, label=r"Text $formula$", "r-", lw=2)
l2 = fig2.add_subplot(111).plot(x2,y2, label=r"$legend2$" ,"g--", lw=3)
fig2.add_subplot(111).legend((l1,l2), loc=0)
# axes:
fig2.add_subplot(111).grid(True)
fig2.add_subplot(111).set_xticks(arange(1,3,0.5))
fig2.add_subplot(111).axis(xmin=3, xmax=6) # there're also ymin, ymax
fig2.add_subplot(111).axis([0,4,3,6]) # all!
fig2.add_subplot(111).set_xlim([0,4])
fig2.add_subplot(111).set_ylim([3,6])
# labels:
fig2.add_subplot(111).set_xlabel(r"x $2^2$", fontsize=15, color = "r")
fig2.add_subplot(111).set_ylabel(r"y $2^2$")
fig2.add_subplot(111).set_title(r"title $6^4$")
fig2.add_subplot(111).text(2, 5.5, r"an equation: $E=mc^2$", fontsize=15, color = "y")
fig2.add_subplot(111).text(3, 2, unicode('f\374r', 'latin-1'))
# saving:
fig2.savefig("fig2.png")
So - what exactly do You want to be configured?
I think you have not installed these features. see below in picture.
I also suffered from this problem some days ago. After installing this feature then I solved it. If you have not installed this feature then installed it.
Install Process:
You shouldn't use flag e
(or eval
in general).
You can also use T-Regx library
pattern('(^|_)([a-z])')->replace($word)->by()->group(2)->callback('strtoupper');
Use Array
's sort()
method, eg
myArray.sort(function(a, b) {
return a.distance - b.distance;
});
I would just do
var list = new List<string> { "hello" };
(Since I use Gson quite liberally, I am sharing a Gson based approach)
Gson gson = new Gson();
Map<Object,Object> attributes = gson.fromJson(gson.toJson(value),Map.class);
What it does is:
gson.toJson(value)
will serialize your object into its equivalent Json representation. gson.fromJson
will convert the Json string to specified object. (in this example - Map
)There are 2 advantages with this approach:
toJson
method.$img_file='http://www.somedomain.com/someimage.jpg'
$img_file=file_get_contents($img_file);
$file_loc=$_SERVER['DOCUMENT_ROOT'].'/some_dir/test.jpg';
$file_handler=fopen($file_loc,'w');
if(fwrite($file_handler,$img_file)==false){
echo 'error';
}
fclose($file_handler);
When you are in the context of a trigger you have access to the logical table INSERTED which contains all the rows that have just been inserted to the table. You can build your insert to the other table based on a select from Inserted.
If you are running Ansible >= 2.0 there is also the dirname filter you can use to extract the directory part of a path. That way you can just use one variable to hold the entire path to make sure both tasks never get out of sync.
So for example if you have playbook with dest_path
defined in a variable like this you can reuse the same variable:
- name: My playbook
vars:
dest_path: /home/ubuntu/some_dir/some_file.txt
tasks:
- name: Make sure destination dir exists
file:
path: "{{ dest_path | dirname }}"
state: directory
recurse: yes
# now this task is always save to run no matter how dest_path get's changed arround
- name: Add file or template to remote instance
template:
src: foo.txt.j2
dest: "{{ dest_path }}"
The Exception it self says it all java.lang.ClassNotFoundException: org.json.JSONObject
You have not added the necessary jar file which will be having org.json.JSONObject
class to your classpath
.

To pass info to a fragment , you setArguments when you create it, and you can retrieve this argument later on the method onCreate or onCreateView of your fragment.
On the newInstance function of your fragment you add the arguments you wanna send to it:
/**
* Create a new instance of DetailsFragment, initialized to
* show the text at 'index'.
*/
public static DetailsFragment newInstance(int index) {
DetailsFragment f = new DetailsFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("index", index);
f.setArguments(args);
return f;
}
Then inside the fragment on the method onCreate
or onCreateView
you can retrieve the arguments like this:
Bundle args = getArguments();
int index = args.getInt("index", 0);
If you want now communicate from your fragment with your activity (sending or not data), you need to use interfaces. The way you can do this is explained really good in the documentation tutorial of communication between fragments. Because all fragments communicate between each other through the activity, in this tutorial you can see how you can send data from the actual fragment to his activity container to use this data on the activity or send it to another fragment that your activity contains.

io.StringIO is another option for getting XML into xml.etree.ElementTree:
import io
f = io.StringIO(xmlstring)
tree = ET.parse(f)
root = tree.getroot()
Hovever, it does not affect the XML declaration one would assume to be in tree
(although that's needed for ElementTree.write()). See How to write XML declaration using xml.etree.ElementTree.
Avoid /etc/*release* files and run this command instead, it is far more reliable and gives more details:
rpm -qia '*release*'
I had a similar problem but I was trying to restore from lower to higher version (correct). The problem was however in insufficient rights. When I logged in with "Windows Authentication" I was able to restore the database.
From the jQuery documentation:
As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().
This error can also be caused by leaving out inject when initializing a service/factory or whatever. For example, it can be thrown by doing this:
var service;
beforeEach(function(_TestService_) {
service = _TestService_;
});
To fix it just wrap the function with inject to properly retrieve the service:
var service;
beforeEach(inject(function(_TestService_) {
service = _TestService_;
}));
you can use altsoft xml2pdf lib for this
I was getting crazy because none of the answers here worked for me.
To show the menu I had to call: setSupportActionBar(toolbar)
Done!
Note: if your toolbar
view isn't in the same activity layout you can't use the call above directly from your activity class, in this case you'll need to get that activity from your fragment class and then call the setSupportActionBar(toolbar)
. Remembering: your activity class should extends the AppCompatActivity.
Hope that this answer help you.

The git merge-base
command can be used to find a common ancestor. So if my_experiment has not been merged into master yet and my_experiment was created from master you could:
git log --oneline `git merge-base my_experiment master`..my_experiment
^\d{5}(?:[-\s]\d{4})?$
^
= Start of the string.\d{5}
= Match 5 digits (for condition 1, 2, 3)(?:…)
= Grouping[-\s]
= Match a space (for condition 3) or a hyphen (for condition 2)\d{4}
= Match 4 digits (for condition 2, 3)…?
= The pattern before it is optional (for condition 1)$
= End of the string."matt b" has it right, but to be specific, the "install" goal copies your built target to the local repository on your file system; useful for small changes across projects not currently meant for the full group.
The "deploy" goal uploads it to your shared repository for when your work is finished, and then can be shared by other people who require it for their project.
In your case, it seems that "install" is used to make the management of the deployment easier since CI's local repo is the shared repo. If CI was on another box, it would have to use the "deploy" goal.
There is no such thing as a byte or short literal. You need to cast to short using (short)100
You can do something like this:
public myform()
{
InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
}
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
this.myTableAdapter.Fill(this.myDataSet.someTable);
comboBox1.SelectedItem = null;
comboBox1.SelectedText = "--select--";
}
sys_guid() is a poor option, as other answers have mentioned. One way to generate UUIDs and avoid sequential values is to generate random hex strings yourself:
select regexp_replace(
to_char(
DBMS_RANDOM.value(0, power(2, 128)-1),
'FM0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'),
'([a-f0-9]{8})([a-f0-9]{4})([a-f0-9]{4})([a-f0-9]{4})([a-f0-9]{12})',
'\1-\2-\3-\4-\5') from DUAL;
Environment.NewLine;
A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.
My cause of issue seems very uncommon to me, not sure if anybody else gets the error under same condition, I found the cause by diffing previous commits, here you go :
Via my build.gradle I was using these 2 compiler options, and commenting out this line fixed the issue
//compileJava.options.compilerArgs = ['-Xlint:unchecked','-Xlint:deprecation']
In one of my projects there was a nuget packages with higher version of System.Net.Http. and in my startup project there reference to System.Net.Http v 4.0.0 , i just installed System.Net.Http nuget package in my startup project and the problem solved
Remember for jQuery 1.6+ you should use the .prop()
function.
$("input").prop('disabled', true);
$("input").prop('disabled', false);
var groupedCustomerList = CustomerList
.GroupBy(u => u.GroupID, u=>{
u.Name = "User" + u.Name;
return u;
}, (key,g)=>g.ToList())
.ToList();
If you don't want to change the original data, you should add some method (kind of clone and modify) to your class like this:
public class Customer {
public int ID { get; set; }
public string Name { get; set; }
public int GroupID { get; set; }
public Customer CloneWithNamePrepend(string prepend){
return new Customer(){
ID = this.ID,
Name = prepend + this.Name,
GroupID = this.GroupID
};
}
}
//Then
var groupedCustomerList = CustomerList
.GroupBy(u => u.GroupID, u=>u.CloneWithNamePrepend("User"), (key,g)=>g.ToList())
.ToList();
I think you may want to display the Customer
differently without modifying the original data. If so you should design your class Customer
differently, like this:
public class Customer {
public int ID { get; set; }
public string Name { get; set; }
public int GroupID { get; set; }
public string Prefix {get;set;}
public string FullName {
get { return Prefix + Name;}
}
}
//then to display the fullname, just get the customer.FullName;
//You can also try adding some override of ToString() to your class
var groupedCustomerList = CustomerList
.GroupBy(u => {u.Prefix="User", return u.GroupID;} , (key,g)=>g.ToList())
.ToList();
Just one other thing to confirm as some people are copy/pasting example code from the Internet to get started. Make sure you have MySQL entered here:
... $dbh = new PDO ("mysql: ...
In some examples this shows
$dbh = new PDO ("dblib ...
you have to create an entry inside res/menu,
override onCreateOptionsMenu
and inflate it
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.yourentry, menu);
return true;
}
an entry for the menu could be:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/action_cart"
android:icon="@drawable/cart"
android:orderInCategory="100"
android:showAsAction="always"/>

JFrame and JApplet are top level containers. If you wish to create a desktop application, you will use JFrame and if you plan to host your application in browser you will use JApplet.
JComponent is an abstract class for all Swing components and you can use it as the base class for your new component. JPanel is a simple usable component you can use for almost anything.
Since this is for a fun project, the simplest way for you is to work with JPanel and then host it inside JFrame or JApplet. Netbeans has a visual designer for Swing with simple examples.
You can also use the AWS Data Wrangler:
import awswrangler as wr
wr.s3.to_csv(
df=df,
path="s3://...",
)
Note that it will handle multipart upload for you to make the upload faster.
If you're using Homebrew /usr/local/bin should already be at the front of $PATH
or at least come before /usr/bin. If you now run brew link --force openssl
in your terminal window, open a new one and run which openssl
in it. It should now show openssl
under /usr/local/bin.
Try using ,
$('#points').val(request.responseText);
You can filter using where
Job.includes(:attachments).where(file_type: ["logo", "image"])
(Neither IN
nor ANY
is an "operator". A "construct" or "syntax element".)
Logically, quoting the manual:
IN
is equivalent to= ANY
.
But there are two syntax variants of IN
and two variants of ANY
. Details:
IN
taking a set is equivalent to = ANY
taking a set, as demonstrated here:
But the second variant of each is not equivalent to the other. The second variant of the ANY
construct takes an array (must be an actual array type), while the second variant of IN
takes a comma-separated list of values. This leads to different restrictions in passing values and can also lead to different query plans in special cases:
ANY
is more versatileThe ANY
construct is far more versatile, as it can be combined with various operators, not just =
. Example:
SELECT 'foo' LIKE ANY('{FOO,bar,%oo%}');
For a big number of values, providing a set scales better for each:
Related:
"Find rows where id
is in the given array":
SELECT * FROM tbl WHERE id = ANY (ARRAY[1, 2]);
Inversion: "Find rows where id
is not in the array":
SELECT * FROM tbl WHERE id <> ALL (ARRAY[1, 2]);
SELECT * FROM tbl WHERE id <> ALL ('{1, 2}'); -- equivalent array literal
SELECT * FROM tbl WHERE NOT (id = ANY ('{1, 2}'));
All three equivalent. The first with array constructor, the other two with array literal. The data type can be derived from context unambiguously. Else, an explicit cast may be required, like '{1,2}'::int[]
.
Rows with id IS NULL
do not pass either of these expressions. To include NULL
values additionally:
SELECT * FROM tbl WHERE (id = ANY ('{1, 2}')) IS NOT TRUE;
2 from decimal numbering system in binary is as follows
10
now if you do
2 << 11
it would be , 11 zeros would be padded on the right side
1000000000000
The signed left shift operator "<<" shifts a bit pattern to the left, and the signed right shift operator ">>" shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator ">>>" shifts a zero into the leftmost position, while the leftmost position after ">>" depends on sign extension [..]
left shifting results in multiplication by 2 (*2) in terms or arithmetic
For example
2 in binary 10
, if you do <<1
that would be 100
which is 4
4 in binary 100
, if you do <<1
that would be 1000
which is 8

$style_cell = array(

with this cell set the vertically aligned into the middle.
The answer that accepts empty string:

the *

I see lots of confusion in the comments. Null
, IsNull()
and vbNull
are mainly used for database handling and normally not used in VBScript. If it is not explicitly stated in the documentation of the calling object/data, do not use it.
To test if a variable is uninitialized, use IsEmpty()
. To test if a variable is uninitialized or contains ""
, test on ""
or Empty
. To test if a variable is an object, use IsObject
and to see if this object has no reference test on Is Nothing
.
In your case, you first want to test if the variable is an object, and then see if that variable is Nothing
, because if it isn't an object, you get the "Object Required" error when you test on Nothing
.
snippet to mix and match in your code:
If IsObject(provider) Then
If Not provider Is Nothing Then
' Code to handle a NOT empty object / valid reference
Else
' Code to handle an empty object / null reference
End If
Else
If IsEmpty(provider) Then
' Code to handle a not initialized variable or a variable explicitly set to empty
ElseIf provider = "" Then
' Code to handle an empty variable (but initialized and set to "")
Else
' Code to handle handle a filled variable

If you need to access those certs programmatically it is best to not use the file at all, but access it via the trust manager. The following code is from a OpenJDK Test case (which makes sure the built cacerts collection is not empty):
TrustManagerFactory trustManagerFactory =
TrustManagerFactory.getInstance("PKIX");
trustManagerFactory.init((KeyStore) null);
TrustManager[] trustManagers =
trustManagerFactory.getTrustManagers();
X509TrustManager trustManager =
(X509TrustManager) trustManagers[0];
X509Certificate[] acceptedIssuers =
trustManager.getAcceptedIssuers();
So you don’t have to deal with file location or keystore password.
You need the following permissions in your manifest file:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
Then you can use the following in your activity class:
WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);
Use the following to check if it's enabled or not
boolean wifiEnabled = wifiManager.isWifiEnabled()
