To reorder the rows of a DataFrame just use a list as follows.
df = df[['Mid', 'Net', 'Upper', 'Lower', 'Zsore']]
This makes it very obvious what was done when reading the code later. Also use:
df.columns
Out[1]: Index(['Net', 'Upper', 'Lower', 'Mid', 'Zsore'], dtype='object')
Then cut and paste to reorder.
For a DataFrame with many columns, store the list of columns in a variable and pop the desired column to the front of the list. Here is an example:
cols = [str(col_name) for col_name in range(1001)]
data = np.random.rand(10,1001)
df = pd.DataFrame(data=data, columns=cols)
mv_col = cols.pop(cols.index('77'))
df = df[[mv_col] + cols]
Now df.columns
has.
Index(['77', '0', '1', '2', '3', '4', '5', '6', '7', '8',
...
'991', '992', '993', '994', '995', '996', '997', '998', '999', '1000'],
dtype='object', length=1001)
Instead of shifting by one position you can make this function more general using module like this.
int[] original = { 1, 2, 3, 4, 5, 6 };
int[] reordered = new int[original.length];
int shift = 1;
for(int i=0; i<original.length;i++)
reordered[i] = original[(shift+i)%original.length];

In this case, the solution was to change the classpath order of the module in my war file. That is, open up the war application in the WAS console under and select the client module(s). In the module configuration, set the class-loading to be "parent last".
This is found in the WAS console:
you should use regular expressions to find all you need:
import re
p = re.compile(r'(\d+)') # a pattern for a number
for line in file :
if num in p.findall(line) :
print line
regular expression will return you all numbers in a line as a list, for example:
>>> re.compile(r'(\d+)').findall('123kh234hi56h9234hj29kjh290')
['123', '234', '56', '9234', '29', '290']
so you don't match '200' or '220' for '20'.
Here's a variation of Shiv Kumar's answer, using Newtonsoft.Json (aka Json.NET):
public static bool SendAnSMSMessage(string message)
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = "POST";
var serializer = new Newtonsoft.Json.JsonSerializer();
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
using (var tw = new Newtonsoft.Json.JsonTextWriter(streamWriter))
{
serializer.Serialize(tw,
new {method= "send",
@params = new string[]{
"IPutAGuidHere",
"[email protected]",
"MyTenDigitNumberWasHere",
message
}});
}
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var responseText = streamReader.ReadToEnd();
//Now you have your response.
//or false depending on information in the response
return true;
}
}
Convert text to date format via the "Data" tab.
Highlight the relevant section and then select from the top menu Data> Datat Tools > Text to Column (depending on your version).
Choose the "Delimited" option.
Toggle through the Delimiter options until the entry appears in the desired format, and select "Next".
Under the Data format, select Date (DMY)
Select "finish" and the issue should be resolved.
If you want to add you custom Overlay screen on Layout, you can create a Custom Linear Layout and get control of drawing and key events. You can my tutorial- Overlay on Android Layout- http://prasanta-paul.blogspot.com/2010/08/overlay-on-android-layout.html
Understanding the language syntax is important when considering clarity of code. Consider copying a character string, for example with post-increment:
char a[256] = "Hello world!";
char b[256];
int i = 0;
do {
b[i] = a[i];
} while (a[i++]);
We want the loop to execute through encountering the zero character (which tests false) at the end of the string. That requires testing the value pre-increment and also incrementing the index. But not necessarily in that order - a way to code this with the pre-increment would be:
int i = -1;
do {
++i;
b[i] = a[i];
} while (a[i]);
It is a matter of taste which is clearer and if the machine has a handfull of registers both should have identical execution time, even if a[i] is a function that is expensive or has side-effects. A significant difference might be the exit value of the index.
I had this path in my machine:
C:/xampp5.0/htdocs/project-recordando-symfony/project-recordando-symfony
Then I ran composer install
or/and composer update
and it returned this error:
ErrorException ZipArchive::extractTo...
That error is because your path is too much long, I changed to:
C:/xampp5.0/htdocs/p-symfony/*
and worked!
If I get you right, you want something that seems to be the opposite of what is desired normally: you want a horizontal layout for small screens and vertically stacked elements on large screens. You may achieve this in a way like this:
<div class="container">
<div class="row">
<div class="hidden-md hidden-lg col-xs-3 col-xs-offset-6">a</div>
<div class="hidden-md hidden-lg col-xs-3">b</div>
</div>
<div class="row">
<div class="hidden-xs hidden-sm">c</div>
</div>
</div>
On small screens, i.e. xs and sm, this generates one row with two columns with an offset of 6. On larger screens, i.e. md and lg, it generates two vertically stacked elements in full width (12 columns).
You can use this code:
// Create an array that matches any country to its id (as String):
String[][] countriesId = new String[NUMBER_OF_COUNTRIES_SUPPORTED][];
// Initialize the array, where the first column will be the country's name (in uppercase) and the second column will be its id (as String):
countriesId[0] = new String[] {"US", String.valueOf(R.drawable.us)};
countriesId[1] = new String[] {"FR", String.valueOf(R.drawable.fr)};
// and so on...
// And after you get the variable "countryCode":
int i;
for(i = 0; i<countriesId.length; i++) {
if(countriesId[i][0].equals(countryCode))
break;
}
// Now "i" is the index of the country
img.setImageResource(Integer.parseInt(countriesId[i][1]));
On latest version of NPM you can just do:
npm install gitAuthor/gitRepo#tag
If the repo is a valid NPM package it will be auto-aliased in package.json as:
{
"NPMPackageName": "gitAuthor/gitRepo#tag"
}
If you could add this to @justingordon 's answer there is no need for manual aliasing now !
public string MakeRelativePath(string workingDirectory, string fullPath)
{
string result = string.Empty;
int offset;
// this is the easy case. The file is inside of the working directory.
if( fullPath.StartsWith(workingDirectory) )
{
return fullPath.Substring(workingDirectory.Length + 1);
}
// the hard case has to back out of the working directory
string[] baseDirs = workingDirectory.Split(new char[] { ':', '\\', '/' });
string[] fileDirs = fullPath.Split(new char[] { ':', '\\', '/' });
// if we failed to split (empty strings?) or the drive letter does not match
if( baseDirs.Length <= 0 || fileDirs.Length <= 0 || baseDirs[0] != fileDirs[0] )
{
// can't create a relative path between separate harddrives/partitions.
return fullPath;
}
// skip all leading directories that match
for (offset = 1; offset < baseDirs.Length; offset++)
{
if (baseDirs[offset] != fileDirs[offset])
break;
}
// back out of the working directory
for (int i = 0; i < (baseDirs.Length - offset); i++)
{
result += "..\\";
}
// step into the file path
for (int i = offset; i < fileDirs.Length-1; i++)
{
result += fileDirs[i] + "\\";
}
// append the file
result += fileDirs[fileDirs.Length - 1];
return result;
}
This code is probably not bullet-proof but this is what I came up with. It's a little more robust. It takes two paths and returns path B as relative to path A.
example:
MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\junk\\readme.txt")
//returns: "..\\..\\junk\\readme.txt"
MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\foo\\bar\\docs\\readme.txt")
//returns: "docs\\readme.txt"
Add the following to your ~/.gitconfig
file
[alias]
cat = "!git show \"$1:$2\" #"
And then try this
git cat BRANCHNAME FILEPATH
Personally I prefer separate parameters without a colon. Why? This choice mirrors the parameters of the checkout
command, which I tend to use rather frequently and I find it thus much easier to remember than the bizarro colon-separated parameter of the show
command.
An executor service can be used to manage multiple threads including status and completion. See http://programmingexamples.wikidot.com/executorservice
@delato468 comment must be listed as a solution as it worked for me.
In addition to defining the parameter, the user must pass it too at the time of calling the function
fetch_data(PDO $pdo, $cat_id)
All of these look like overkill (or don't work)... just do this:
$http.post(loginUrl, `username=${ encodeURIComponent(username) }` +
`&password=${ encodeURIComponent(password) }` +
'&grant_type=password'
).success(function (data) {

I guess this may be an issue about limited contexts, e.g. WYIWYG editors on a web system used by not-programmers users, that limits the possibilities of follow the standards. Sometimes (like TinyMCE), it's a lib that puts your content/code inside a textarea
tag, that is rendered by the editor as a big div
tag. And sometimes, it may be an old version of these editors.
I'm supposing that:
stylesheets
. Actually, it would be impractical for the admins (or webdevs), considering the number of requests in that sense that they would have.In some cases, without use style
rules, it may be a very poor design experience. So, yes, these users need customization. Okay, but what would be the solutions, in this scenario? Considering the different ways to insert CSS in a html
page, I suppose these solutions:
Ask to your system adm for including some CSS rules at the system's stylesheets
. This will be an external or internal CSS solution. As already said, it might be not possible.
<link>
on <body>
Use external style sheet on the body
tag, i.e., use of the link
tag inside the area you have access (that will be, on the site, inside the body
tag and not in the head
tag). Some sources says this is okay, but "not a good practice", like MDN:
A
<link>
element can occur either in the<head>
or<body>
element, depending on whether it has a link type that is body-ok. For example, thestylesheet
link type is body-ok, and therefore<link rel="stylesheet">
is permitted in the body. However, this isn't a good practice to follow; it makes more sense to separate your<link>
elements from your body content, putting them in the<head>
.
Some others, restrict it to the <head>
section, like w3schools:
Note: This element goes only in the head section, but it can appear any number of times.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file foo.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<link href="bar.css" type="text/css" rel="stylesheet">
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
</body>
</html>
And then a CSS file, at the same directory, called bar.css
:
.test1 {
color: green;
};
Well, this will just looks possible if you have how upload an CSS file somewhere at the institution system. Maybe this would be the case.
<style>
on <body>
Use internet style sheet on the body
tag, i.e., use of the style
tag inside the area you have access (that will be, on the site, inside the body
tag and not in the head
tag). This is what Charles Salvia's and Sz's answers here are about. Choosing this option, consider their concerns.
Alert
These ones are related to modifying the <head>
element of the page. Maybe this will not be allowed by the institution's system administrators. So, it's recommended to ask them permission first.
Okay, supposing permission granted, the strategy is access the <head>
. How? JavaScript methods.
<link>
on <head>
This is another version of the 2nd option. Use external style sheet on the <head>
tag, i.e., use of the <link>
element outside the area you have access (that will be, on the site, not inside the body
tag and yes inside the head
tag). This solution complies with the recommendations of MDN and w3schools, as cited above, on 2nd option solution. A new Link
object will be created.
To solve the matter through JS, there are many ways but at the following codelines I demonstrate one simple.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file f.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
<script>
// JS code here
</script>
</body>
</html>
Inside the script
tag:
var newLink = document.createElement("link");
newLink.href = "bar.css";
newLink.rel = "stylesheet";
newLink.type = "text/css";
document.getElementsByTagName("head")[0].appendChild(newLink);
And then at the CSS file, at the same directory, called bar.css
(as at the 2nd option):
.test1 {
color: green;
};
As I already said: this will just looks possible if you have how upload an CSS file somewhere at the institution system.
<style>
on <head>
Use new internal style sheet on the <head>
tag, i.e., use of a new <style>
element outside the area you have access (that will be, on the site, not inside the body
tag and yes inside the head
tag). A new Style
object will be created.
This is solved through JS. One simple way is demonstrated following.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file foobar.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
<script>
// JS code here
</script>
</body>
</html>
Inside the script
tag:
var newStyle = document.createElement("style");
newStyle.innerHTML =
"h1.test1 {"+
"color: green;"+
"}";
document.getElementsByTagName("head")[0].appendChild(newStyle);
<style>
on <head>
Use an existing internal style sheet on the <head>
tag, i.e., use of a <style>
element outside the area you have access (that will be, on the site, not inside the body
tag and yes inside the head
tag), if some exists. A new Style
object will be created or a CSSStyleSheet
object will be used (in the code of the solution adopted here).
This is at some point of view risky.
First, because it may not exists some <style>
object. Depending of the way you implement this solution, you may get undefined
return (the system may use external style sheet).
Second, because you will be editing the system design author's work (authorship issues).
Third, because it may not be allowed at your institution's IT politics of safety.
So, do ask permission to do this (as at in other JS solutions).
Supposing, again, permission was granted:
You will need to consider some restrictions of the method available to this way: insertRule()
. The solution proposed uses the default scenario, and a operation at the first stylesheet
, if some exists.
I tested it here (desktop environment, on a browser) and it works for me.
Create a file foo_bar.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 class="test1">Hello</h1>
<h1 class="test2">World</h1>
<script>
// JS code here
</script>
</body>
</html>
Inside the script
tag:
function demoLoop(){ // remove this line
var elmnt = document.getElementsByTagName("style");
if (elmnt.length === 0) {
// there isn't style objects, so it's more interesting create one
var newStyle = document.createElement("style");
newStyle.innerHTML =
"h1.test1 {" +
"color: green;" +
"}";
document.getElementsByTagName("head")[0].appendChild(newStyle);
} else {
// Using CSSStyleSheet interface
var firstCSS = document.styleSheets[0];
firstCSS.insertRule("h1.test2{color:blue;}"); // at this way (without index specified), will be like an Array unshift() method
}
} // remove this too
demoLoop(); // remove this too
demoLoop(); // remove this too
Another approach to this solution it's using CSSStyleDeclaration
object (docs at w3schools and MDN). But it may not be interesting, considering the risk to override existing rules on the system's CSS.
Use inline CSS. This solve the problem, although depending of the page size (in code lines), the maintenance (by the author itself or other assigned person) of code can be very difficult.
But depending of the context of your role at the institution, or its web system security policies, this might be the unique available solution to you.
Create a file _foobar.html
:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1 style="color: green;">Hello</h1>
<h1 style="color: blue;">World</h1>
</body>
</html>
How is a browser supposed to render css which is non contiguous?
- Is it supposed to generate some data structure using all the css styles on a page and use that for rendering?
- Or does it render using style information in the order it sees?

For a more accurate answer, I suggest Google these articles:
we're talking about images not loading on mobile, right? so what if you just did an @media (min-width: 400px){background-image:thing.jpg}
wouldn't it then only look for the image at above a certain screen width?
why not using?

if you got error at Anchor tag,just replace "Onclick" with "href" or "href" with "Onclick"
What's you've got there should be fine to work, but there is no actual "Is Mobile/Tablet" media query so you're always going to be stuck.
There are media queries for common breakpoints , but with the ever changing range of devices they're not guaranteed to work moving forwards.
The idea is that your site maintains the same brand across all sizes, so you should want the styles to cascade across the breakpoints and only update the widths and positioning to best suit that viewport.
To further the answer above, using Modernizr with a no-touch test will allow you to target touch devices which are most likely tablets and smart phones, however with the new releases of touch based screens that is not as good an option as it once was.
Support, unfortunately, is brutal at best. Here's a post on the topic:
https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/
And the post content:
I have a slightly different approach that might be useful/more beneficial to some.
Under your main project folder, create a resource folder. Your folder structure should look something like this.
Go to the properties of your project. You can do this by right clicking on your project in the Projects tab window and selecting Properties in the drop down menu.
Under categories on the left side, select Sources.
In Source Package Folders on the right side, add your resource folder using the Add Folder button. Once you click OK, you should see a Resources folder under your project.
You should now be able to pull resources using this line or similar approach:
MyClass.class.getResource("/main.jpg");
If you were to create a package called Images under the resources folder, you can retrieve the resource like this:
MyClass.class.getResource("/Images/main.jpg");
Do you want the files to save as UTF-8 because you are using special characters that would be lost in ASCII encoding? If that's the case, then there is a VS2008 global setting in Tools > Options > Environment > Documents
, named Save documents as Unicode when data cannot be saved in codepage
. When this is enabled, VS2008 will save as Unicode if certain characters cannot be represented in the otherwise-default codepage.
Also, which files are not being saved as UTF-8? All of my .cs, .csproj, .sln, .config, .as*x, etc, all save as UTF-8 (with signature, the byte order marks), by default.
instance.__class__.__name__
example:
>>> class A():
pass
>>> a = A()
>>> a.__class__.__name__
'A'
If you have to get an attribute that is not the ID. I would use CollectionUtils.
Dog someDog = new Dog();
Dog dog = CollectionUtils(dogList, new Predicate() {
@Override
public boolean evaluate(Object o)
{
Dog d = (Dog)o;
return someDog.getName().equals(d.getName());
}
});
Though this seems to be an old question with many answers I'm posting another one, because it provides information about another approaches (looking more convenient than already mentioned), and the question itself remains actual.
First, there is a blogpost Running multiple versions of Google Chrome on Windows. It describes a method which works, but has 2 drawbacks:
Second method is a preferred one, which I'm currently using. It relies on portable versions of Chrome, which become available for every stable release at the portableapps.com.
The only requirement of this method is that existing Chrome version should not run during installation of a next version. Of course, each version must be installed in a separate directory. This way, after installation, you can run Chromes of different versions in parallel. Of course, there is a drawback in this method as well:
-split outputs an array, and you can save it to a variable like this:
$a = -split 'Once upon a time'
$a[0]
Once
Another cute thing, you can have arrays on both sides of an assignment statement:
$a,$b,$c = -split 'Once upon a'
$c
a
find . -type d > list.txt
Will list all directories and subdirectories under the current path. If you want to list all of the directories under a path other than the current one, change the .
to that other path.
If you want to exclude certain directories, you can filter them out with a negative condition:
find . -type d ! -name "~snapshot" > list.txt
One another source of the issue with collations is mysql.proc
table. Check collations of your storage procedures and functions:
SELECT
p.db, p.db_collation, p.type, COUNT(*) cnt
FROM mysql.proc p
GROUP BY p.db, p.db_collation, p.type;
Also pay attention to mysql.proc.collation_connection
and mysql.proc.character_set_client
columns.
Here's pure javascript example of handling classes during scrolling.
You'd probably want to throttle handling scroll events, more so as handler logic gets more complex, in that case throttle
from lodash
lib comes in handy.
And if you're doing spa, keep in mind that you need to clear event listeners with removeEventListener
once they're not needed (eg during onDestroy
lifecycle hook of your component, like destroyed()
for Vue, or maybe return function of useEffect
hook for React).

In your function definition you're constraining sets a and b to the same type. You can also write
public <X,Y> void myFunction(Set<X> s1, Set<Y> s2){...}
Related, you can use the following if you want to have a vector completely ready to go in a quick statement (e.g. immediately passing to another function):
#define VECTOR(first,...) \
([](){ \
static const decltype(first) arr[] = { first,__VA_ARGS__ }; \
std::vector<decltype(first)> ret(arr, arr + sizeof(arr) / sizeof(*arr)); \
return ret;})()
example function
template<typename T>
void test(std::vector<T>& values)
{
for(T value : values)
std::cout<<value<<std::endl;
}
example use
test(VECTOR(1.2f,2,3,4,5,6));
though be careful about the decltype, make sure the first value is clearly what you want.
The main reason was first event's last access time was current time(file write or changed time). then second event was file's original last access time. I solve under code.
var lastRead = DateTime.MinValue;
Watcher = new FileSystemWatcher(...)
{
NotifyFilter = NotifyFilters.FileName | NotifyFilters.LastWrite,
Filter = "*.dll",
IncludeSubdirectories = false,
};
Watcher.Changed += (senderObject, ea) =>
{
var now = DateTime.Now;
var lastWriteTime = File.GetLastWriteTime(ea.FullPath);
if (now == lastWriteTime)
{
return;
}
if (lastWriteTime != lastRead)
{
// do something...
lastRead = lastWriteTime;
}
};
Watcher.EnableRaisingEvents = true;
For py3

Some troubleshooting help here:
The UberNeo response is Ok and i like it because you do not have to modify anything else except the TD. The only point is that you also have to add "white-space:normal" to the style in order to maintain the responsive characteristics of the table, if not, at certain resolutions the wrap is not made and the scroll of the table does not appear.
style="word-wrap: break-word;min-width: 160px;max-width: 160px;white-space:normal;"
One way of doing this without changing Volley
's source code is to check for the response data in the VolleyError
and parse it your self.
As of f605da3 commit
, Volley
throws a ServerError
exception that contains the raw network response.
So you can do something similar to this in your error listener:
/* import com.android.volley.toolbox.HttpHeaderParser; */
public void onErrorResponse(VolleyError error) {
// As of f605da3 the following should work
NetworkResponse response = error.networkResponse;
if (error instanceof ServerError && response != null) {
try {
String res = new String(response.data,
HttpHeaderParser.parseCharset(response.headers, "utf-8"));
// Now you can use any deserializer to make sense of data
JSONObject obj = new JSONObject(res);
} catch (UnsupportedEncodingException e1) {
// Couldn't properly decode data to string
e1.printStackTrace();
} catch (JSONException e2) {
// returned data is not JSONObject?
e2.printStackTrace();
}
}
}
For future, if Volley
changes, one can follow the above approach where you need to check the VolleyError
for raw data that has been sent by the server and parse it.
I hope that they implement that TODO
mentioned in the source file.
You can also try to write different elements in different cookies. Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system. Consider explode() to set one cookie with multiple names and values. It is not recommended to use serialize() for this purpose, because it can result in security holes. Look at setcookie PHP function for more details
declare @listOfIDs table (id int);
insert @listOfIDs(id) values(1),(2),(3);
select *
from TabA
where TabA.ID in (select id from @listOfIDs)
or
declare @listOfIDs varchar(1000);
SET @listOfIDs = ',1,2,3,'; --in this solution need put coma on begin and end
select *
from TabA
where charindex(',' + CAST(TabA.ID as nvarchar(20)) + ',', @listOfIDs) > 0
I think you should consider using the shelve
module which provides persistent file-backed dictionary-like objects. It's easy to use in place of a "real" dictionary because it almost transparently provides your program with something that can be used just like a dictionary, without the need to explicitly convert it to a string and then write to a file (or vice-versa).
The main difference is needing to initially open()
it before first use and then close()
it when you're done (and possibly sync()
ing it, depending on the writeback
option being used). Any "shelf" file objects create can contain regular dictionaries as values, allowing them to be logically nested.
Here's a trivial example:
import shelve
shelf = shelve.open('mydata') # open for reading and writing, creating if nec
shelf.update({'one':1, 'two':2, 'three': {'three.1': 3.1, 'three.2': 3.2 }})
shelf.close()
shelf = shelve.open('mydata')
print shelf
shelf.close()
Output:
{'three': {'three.1': 3.1, 'three.2': 3.2}, 'two': 2, 'one': 1}

Git reset has 5 main modes: soft, mixed, merged, hard, keep. The difference between them is to change or not change head, stage (index), working directory.
Git reset --hard will change head, index and working directory.
Git reset --soft will change head only. No change to index, working directory.
So in other words if you want to undo your commit, --soft should be good enough. But after that you still have the changes from bad commit in your index and working directory. You can modify the files, fix them, add them to index and commit again.
With the --hard, you completely get a clean slate in your project. As if there hasn't been any change from the last commit. If you are sure this is what you want then move forward. But once you do this, you'll lose your last commit completely. (Note: there are still ways to recover the lost commit).
As much as I love this framework, I hate when it acts like crap.
DB::enableQueryLog()
is totally useless. DB::listen
is equally useless. It showed part of the query when I said $query->count()
, but if I do $query->get()
, it has nothing to say.
The only solution that appears to work consistently is to intentionally put some syntax or other error in the ORM parameters, like an nonexistent column/table name, run your code on the command line while in debug mode, and it will spit out the SQL error with the full frickin' query finally. Otherwise, hopefully the error appears in the log file if ran from the web server.

If your business class is directly used by your UI is preferrable to use IDataErrorInfo because it put logic closer to their owner.
If your business class is a stub class created by a reference to an WCF/XmlWeb service then you can not/must not use IDataErrorInfo nor throw Exception for use with ExceptionValidationRule. Instead you can:
For jQuery 1.9+ as Dunstkreis mentioned .data('events') was removed. But you can use another hack (it is not recommended to use undocumented possibilities) $._data($(this).get(0), 'events') instead and solution provided by anurag will look like:
$.fn.bindFirst = function(name, fn) {
this.bind(name, fn);
var handlers = $._data($(this).get(0), 'events')[name.split('.')[0]];
var handler = handlers.pop();
handlers.splice(0, 0, handler);
};
In My case my web project was not loaded properly ( it was showing project unavailable ) then I had to reload my web project after opening my visual studio in admin mode then everything worked fine.
A cleaner way is to set connectionString in xml file, for example Web.Confing(WepApplication)
or App.Config(StandAloneApplication)
.
<connectionStrings>
<remove name="myConn"/>
<add name="myConn" connectionString="User ID=sa;Password=XXXXX;Initial Catalog=qualitaBorri;Data Source=PC_NAME\SQLEXPRESS;Connection Timeout=60"/>
</connectionStrings>
By code you can get connection in this way:
public static SqlConnection getConnection()
{
string conn = string.Empty;
conn = System.Configuration.ConfigurationManager.ConnectionStrings["myConn"].ConnectionString;
SqlConnection aConnection = new SqlConnection(conn);
return aConnection;
}
You can set ConnectionTimeout
only you create a instance.
When instance is create you don't change this value.

ASP.NET always generate asp:Button
as an input type=submit
.
If you want a button which doesn't do a post, but need some control for the element on the server side, create a simple HTML input with attributes type=button
and runat=server
.
If you disable click actions doing OnClientClick=return false
, it won't do anything on click, unless you create a function like:
function btnClick() {
// do stuff
return false;
}

Tight coupling means classes and objects are dependent on one another. In general, tight coupling is usually not good because it reduces the flexibility and re-usability of the code while Loose coupling means reducing the dependencies of a class that uses the different class directly.
Tight Coupling The tightly coupled object is an object that needs to know about other objects and is usually highly dependent on each other's interfaces. Changing one object in a tightly coupled application often requires changes to a number of other objects. In the small applications, we can easily identify the changes and there is less chance to miss anything. But in large applications, these inter-dependencies are not always known by every programmer and there is a chance of overlooking changes. Example:
class A {
public int a = 0;
public int getA() {
System.out.println("getA() method");
return a;
}
public void setA(int aa) {
if(!(aa > 10))
a = aa;
}
}
public class B {
public static void main(String[] args) {
A aObject = new A();
aObject.a = 100; // Not suppose to happen as defined by class A, this causes tight coupling.
System.out.println("aObject.a value is: " + aObject.a);
}
}
In the above example, the code that is defined by this kind of implementation uses tight coupling and is very bad since class B knows about the detail of class A, if class A changes the variable 'a' to private then class B breaks, also class A's implementation states that variable 'a' should not be more than 10 but as we can see there is no way to enforce such a rule as we can go directly to the variable and change its state to whatever value we decide.
Output
aObject.a value is: 100
Loose Coupling
Loose coupling is a design goal to reduce the inter-dependencies between components of a system with the goal of reducing the risk that changes in one component will require changes in any other component.
Loose coupling is a much more generic concept intended to increase the flexibility of the system, make it more maintainable and makes the entire framework more stable.
Example:
class A {
private int a = 0;
public int getA() {
System.out.println("getA() method");
return a;
}
public void setA(int aa) {
if(!(aa > 10))
a = aa;
}
}
public class B {
public static void main(String[] args) {
A aObject = new A();
aObject.setA(100); // No way to set 'a' to such value as this method call will
// fail due to its enforced rule.
System.out.println("aObject value is: " + aObject.getA());
}
}
In the above example, the code that is defined by this kind of implementation uses loose coupling and is recommended since class B has to go through class A to get its state where rules are enforced. If class A is changed internally, class B will not break as it uses only class A as a way of communication.
Output
getA() method
aObject value is: 0
You can use the str.split
method: string.split('__')
>>> "MATCHES__STRING".split("__")
['MATCHES', 'STRING']

or you can get permanent solution
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
In case anyone is still struggling with this, as I was all morning today, I have found a solution that works for me:
Installation instructions:
git clone https://github.com/gstarnberger/uncompyle.git
cd uncompyle/
sudo ./setup.py install
Once the program is installed (note: it will be installed to your system-wide-accessible Python packages, so it should be in your $PATH
), you can recover your Python files like so:
uncompyler.py thank_goodness_this_still_exists.pyc > recovered_file.py
The decompiler adds some noise mostly in the form of comments, however I've found it to be surprisingly clean and faithful to my original code. You will have to remove a little line of text beginning with +++ near the end of the recovered file to be able to run your code.
In mi and vivo - Using the above solution is not enough. You must also tell the user to add permission manually. You can help them by opening the right location inside phone settings. Varies for different phone models.
if (RectA.Left < RectB.Right && RectA.Right > RectB.Left &&
RectA.Top > RectB.Bottom && RectA.Bottom < RectB.Top )
or, using Cartesian coordinates
(With X1 being left coord, X2 being right coord, increasing from left to right and Y1 being Top coord, and Y2 being Bottom coord, increasing from bottom to top -- if this is not how your coordinate system [e.g. most computers have the Y direction reversed], swap the comparisons below) ...
if (RectA.X1 < RectB.X2 && RectA.X2 > RectB.X1 &&
RectA.Y1 > RectB.Y2 && RectA.Y2 < RectB.Y1)
Say you have Rect A, and Rect B. Proof is by contradiction. Any one of four conditions guarantees that no overlap can exist:
So condition for Non-Overlap is
NON-Overlap => Cond1 Or Cond2 Or Cond3 Or Cond4
Therefore, a sufficient condition for Overlap is the opposite.
Overlap => NOT (Cond1 Or Cond2 Or Cond3 Or Cond4)
De Morgan's law says
Not (A or B or C or D)
is the same as Not A And Not B And Not C And Not D
so using De Morgan, we have
Not Cond1 And Not Cond2 And Not Cond3 And Not Cond4
This is equivalent to:
RectA.Left < RectB.Right
], andRectA.Right > RectB.Left
], andRectA.Top > RectB.Bottom
], andRectA.Bottom < RectB.Top
]Note 1: It is fairly obvious this same principle can be extended to any number of dimensions.
Note 2: It should also be fairly obvious to count overlaps of just one pixel, change the <
and/or the >
on that boundary to a <=
or a >=
.
Note 3: This answer, when utilizing Cartesian coordinates (X, Y) is based on standard algebraic Cartesian coordinates (x increases left to right, and Y increases bottom to top). Obviously, where a computer system might mechanize screen coordinates differently, (e.g., increasing Y from top to bottom, or X From right to left), the syntax will need to be adjusted accordingly/

driver.switchTo().defaultContent()

I ran into this problem as well and nothing worked. I finally managed to find the solution which works for me. I had zipped content in base64 and this happened to 1 out of a million records...
This is a version of the solution suggested by Simon Sapin.
In case the padding is missing 3 then I remove the last 3 characters.
Instead of "0gA1RD5L/9AUGtH9MzAwAAA=="
We get "0gA1RD5L/9AUGtH9MzAwAA"
missing_padding = len(data) % 4
if missing_padding == 3:
data = data[0:-3]
elif missing_padding != 0:
print ("Missing padding : " + str(missing_padding))
data += '=' * (4 - missing_padding)
data_decoded = base64.b64decode(data)
According to this answer Trailing As in base64 the reason is nulls. But I still have no idea why the encoder messes this up...
Use this SQL to get the first 2000 chars of the BLOB.
SELECT utl_raw.cast_to_varchar2(dbms_lob.substr(<YOUR_BLOB_FIELD>,2000,1)) FROM <YOUR_TABLE>;
Note: This is because, Oracle will not be able to handle the conversion of BLOB that is more than length 2000.
export const users = require('../data'); // presumes @types/node are installed
const foundUser = users.find(user => user.id === 42);
// error: Parameter 'user' implicitly has an 'any' type.ts(7006)
--resolveJsonModule
--resolveJsonModule
compiler option:
import users from "./data.json" // `import` instead of `require`
const foundUser = users.find(user => user.id === 42); // user is strongly typed, no `any`!
There are some alternatives for other cases than static JSON import.
type User = { id: number; name: string /* and others */ }
const foundUser = users.find((user: User) => user.id === 42)
function isUserArray(maybeUserArr: any): maybeUserArr is Array<User> {
return Array.isArray(maybeUserArr) && maybeUserArr.every(isUser)
}
function isUser(user: any): user is User {
return "id" in user && "name" in user
}
if (isUserArray(users)) {
const foundUser = users.find((user) => user.id === 42)
}
You can even switch to assertion functions (TS 3.7+) to get rid of if
and throw an error instead.
function assertIsUserArray(maybeUserArr: any): asserts maybeUserArr is Array<User> {
if(!isUserArray(maybeUserArr)) throw Error("wrong json type")
}
assertIsUserArray(users)
const foundUser = users.find((user) => user.id === 42) // works
A runtime type check library like io-ts
or ts-runtime
can be integrated for more complex cases.
noImplicitAny: false
undermines many useful checks of the type system:
function add(s1, s2) { // s1,s2 implicitely get `any` type
return s1 * s2 // `any` type allows string multiplication and all sorts of types :(
}
add("foo", 42)
Also better provide an explicit User
type for user
. This will avoid propagating any
to inner layer types. Instead typing and validating is kept in the JSON processing code of the outer API layer.
C is a very low-level language, so it permits you to create almost any legal object (.o) file that you can conceive of. You should think of C as basically dressed-up assembly language.
In particular, C does not require functions to be declared before they are used. If you call a function without declaring it, the use of the function becomes it's (implicit) declaration. In a simple test I just ran, this is only a warning in the case of built-in library functions like printf (at least in GCC), but for random functions, it will compile just fine.
Of course, when you try to link, and it can't find foo, then you will get an error.
In the case of library functions like printf, some compilers contain built-in declarations for them so they can do some basic type checking, so when the implicit declaration (from the use) doesn't match the built-in declaration, you'll get a warning.
Add the separator to the li
background and make sure the link doesn't expand to cover the separator, which means the separator won't be click-able.
As setAlpha int has been deprecated, setImageAlpha (int) can be used
ImageView img = (ImageView) findViewById(R.id.img_image);

I had the same question and found this article with a really clean solution:
http://leon.radley.se/2017/01/angular-cli-and-bootstrap-4/
Here are the instructions, but with my simplified solution:
Install Bootstrap 4 (instructions):
npm install --save [email protected]
If needed, rename your src/styles.css to styles.scss and update .angular-cli.json to reflect the change:
"styles": [
"styles.scss"
],
Then add this line to styles.scss:
@import '~bootstrap/scss/bootstrap';
By the time this question was posed there were some kinks with version ranges in maven, but these have been resolved in newer versions of maven. This article captures very well how version ranges work and best practices to better understand how maven understands versions: https://docs.oracle.com/middleware/1212/core/MAVEN/maven_version.htm#MAVEN8855
there is no need to use for cycle
you can benefit from bash parameter expansion functions:
var="a b c";
var=${var// /\\n};
echo -e $var
a
b
c
or just use tr:
var="a b c"
echo $var | tr " " "\n"
a
b
c
There's no need for a parent POM.
You can omit the distributionManagement part entirely in your poms and set it either on your build server or in settings.xml.
To do it on the build server, just pass to the mvn
command:
-DaltSnapshotDeploymentRepository=snapshots::default::https://YOUR_NEXUS_URL/snapshots
-DaltReleaseDeploymentRepository=releases::default::https://YOUR_NEXUS_URL/releases
See https://maven.apache.org/plugins/maven-deploy-plugin/deploy-mojo.html for details which options can be set.
It's also possible to set this in your settings.xml
.
Just create a profile there which is enabled and contains the property.
Example settings.xml:
<settings>
[...]
<profiles>
<profile>
<id>nexus</id>
<properties>
<altSnapshotDeploymentRepository>snapshots::default::https://YOUR_NEXUS_URL/snapshots</altSnapshotDeploymentRepository>
<altReleaseDeploymentRepository>releases::default::https://YOUR_NEXUS_URL/releases</altReleaseDeploymentRepository>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
Make sure that credentials for "snapshots" and "releases" are in the <servers>
section of your settings.xml
The properties altSnapshotDeploymentRepository and altReleaseDeploymentRepository are introduced with maven-deploy-plugin version 2.8. Older versions will fail with the error message
Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter
To fix this, you can enforce a newer version of the plug-in:
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-deploy-plugin</artifactId>
<version>2.8</version>
</plugin>
</plugins>
</pluginManagement>
</build>
I'm not entirely sure if I understood your question, but it seems that you're trying to set value for an input type Date.
If you want to set a value for an input type 'Date', then it has to be formatted as "yyyy-MM-dd" (Note: capital MM for Month, lower case mm for minutes). Otherwise, it will clear the value and leave the datepicker empty.
Let's say you have a button called "DateChanger" and you want to set your datepicker to "22 Dec 2012" when you click it.
<script>
$(document).ready(function () {
$('#DateChanger').click(function() {
$('#dtFrom').val("2012-12-22");
});
});
</script>
<input type="date" id="dtFrom" name="dtFrom" />
<button id="DateChanger">Click</button>
Remember to include JQuery reference.
$(document).ready(function(){
var response;
$.validator.addMethod(
"uniqueUserName",
function(value, element) {
$.ajax({
type: "POST",
url: "http://"+location.host+"/checkUser.php",
data: "checkUsername="+value,
dataType:"html",
success: function(msg)
{
//If username exists, set response to true
response = ( msg == 'true' ) ? true : false;
}
});
return response;
},
"Username is Already Taken"
);
$("#regFormPart1").validate({
username: {
required: true,
minlength: 8,
uniqueUserName: true
},
messages: {
username: {
required: "Username is required",
minlength: "Username must be at least 8 characters",
uniqueUserName: "This Username is taken already"
}
}
});
});
After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:
impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
remap_tablespace=user1:user2 directory=EXPORTDIR \
dumpfile=user1.dmp logfile=E:\Data\user1.log
EXPORTDIR must be defined in oracle as a directory as the system user
create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;
The server at x3.chatforyoursite.com
needs to output the following header:
Access-Control-Allow-Origin: http://www.example.com
Where http://www.example.com
is your website address. You should check your settings on chatforyoursite.com
to see if you can enable this - if not their technical support would probably be the best way to resolve this. However to answer your question, you need the remote site to allow your site to access AJAX responses client side.
So what is the point of "constructor" property? Cannot figure out where it could be useful, any ideas?
The point of the constructor property is to provide some way of pretending JavaScript has classes. One of the things you cannot usefully do is change an object's constructor after it's been created. It's complicated.
I wrote a fairly comprehensive piece on it a few years ago: http://joost.zeekat.nl/constructors-considered-mildly-confusing.html
First add a variable to your SSIS package (Package Scope) - I used FileName, OleRootFilePath, OleProperties, OleProvider. The type for each variable is "string". Then I create a Configuration file (Select each variable - value) - populate the values in the configuration file - Eg: for OleProperties - Microsoft.ACE.OLEDB.12.0; for OleProperties - Excel 8.0;HDR=, OleRootFilePath - Your Excel file path, FileName - FileName
In the Connection manager - I then set the Properties-> Expressions-> Connection string expression dynamically eg:
"Provider=" + @[User::OleProvider] + "Data Source=" + @[User::OleRootFilePath] + @[User::FileName] + ";Extended Properties=\"" + @[User::OleProperties] + "NO \""+";"
This way once you set the variables values and change it in your configuration file - the connection string will change dynamically - this helps especially in moving from development to production environments.
First check the logs why the container failed. Because your restart policy might bring your container back to running status. Better to fix the issue, Then probably you can build a new image with/without fix. Later execute below command

You can use IntStream.iterate()
to get the index:
String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
List<String> nameList = IntStream.iterate(0, i -> i < names.length, i -> i + 1)
.filter(i -> names[i].length() <= i)
.mapToObj(i -> names[i])
.collect(Collectors.toList());
This only works for Java 9 upwards in Java 8 you can use this:
String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
List<String> nameList = IntStream.iterate(0, i -> i + 1)
.limit(names.length)
.filter(i -> names[i].length() <= i)
.mapToObj(i -> names[i])
.collect(Collectors.toList());
I'm assuming what you want to do is run a command without an interface (possibly automatically?). On windows there are a number of options for what you are looking for:
Best: write your program as a windows service. These will start when no one logs into the server. They let you select the user account (which can be different than your own) and they will restart if they fail. These run all the time so you can automate tasks at specific times or on a regular schedule from within them. For more information on how to write a windows service you can read a tutorial online such as (http://msdn.microsoft.com/en-us/library/zt39148a(v=vs.110).aspx).
Better: Start the command and hide the window. Assuming the command is a DOS command you can use a VB or C# script for this. See here for more information. An example is:
Set objShell = WScript.CreateObject("WScript.Shell")
objShell.Run("C:\yourbatch.bat"), 0, True
You are still going to have to start the command manually or write a task to start the command. This is one of the biggest down falls of this strategy.
Hope that helps some!
df.apply(pd.value_counts).fillna(0)
value_counts - Returns object containing counts of unique values
apply - count frequency in every column. If you set axis=1
, you get frequency in every row
fillna(0) - make output more fancy. Changed NaN to 0
This is the best way to get a schema dynamically and add it to the different tables within a database in order to get other information dynamically
select @sql = 'insert #tables SELECT ''[''+SCHEMA_NAME(schema_id)+''.''+name+'']'' AS SchemaTable FROM sys.tables'
exec (@sql)
of course #tables is a dynamic table in the stored procedure

One stupid mistake I did awhile ago that might help some people.
Keep in mind that if you are using ":" in an event like this, the value will not change
var ondrag = (function(event, ui) {
...
nub0x: event.target.offsetLeft + event.target.clientWidth/2;
nub0y = event.target.offsetTop + event.target.clientHeight/2;
...
});
So "nub0x" will initialize with the first event that happens and will never change its value. But "nub0y" will change during the next events.
In my case the mentioned "duplicate entry" error arised after settingmultiDexEnable=true
in the build.gradle.
In order to fully resolve the error first of all have a look at Configure Apps with Over 64K Methods (espescially "Configuring Your App for Multidex with Gradle").
Furthermore search for occurences of the class that causes the "duplicate entry" error using ctrl+n in Android Studio. Determine the module and dependency that contains the duplicate and exclude it from build, e.g.:
compile ('org.roboguice:roboguice:2.0') {
exclude module: 'support-v4'
}
I had to try multiple module labels till it worked. Excluding "support-v4" solves issues related to "java.util.zip.ZipException: duplicate entry: android/support/v4/*"
var mystring = 'This is a string';

Here's an overview of the parameters to the map(function, *sequences)
function:
function
is the name of your function.sequences
is any number of sequences, which are usually lists or tuples. map
will iterate over them simultaneously and give the current values to function
. That's why the number of sequences should equal the number of parameters to your function.It sounds like you're trying to iterate for some of function
's parameters but keep others constant, and unfortunately map
doesn't support that. I found an old proposal to add such a feature to Python, but the map construct is so clean and well-established that I doubt something like that will ever be implemented.
Use a workaround like global variables or list comprehensions, as others have suggested.
margin-left: auto works well. But clean flex box solution would be space-between in the main class. Space between works well if there is two or more elements. I have added a solution for single element as well.

Easiest way to do this in VBA is to create a function that takes in an array, your new amount of rows, and new amount of columns.
Run the below function to copy in all of the old data back to the array after it has been resized.

dim array2 as variant
array2 = array1
reDim array1(1 to num_rows, 1 to num_cols)
for i = lbound(array2, 1) to ubound(array2, 2)
for j = lbound(array2,2) to ubound(array2,2)
array1(i,j) = array2(i,j)
next j
next i
dynamic_preserve = array1
end function
You have done the stored procedure correctly but I think you have not referenced the valido
variable properly. I was looking at some examples and they have put an @ symbol before the parameter like this @Valido
This statement SELECT valido;
should be like this SELECT @valido;
Look at this link mysql stored-procedure: out parameter. Notice the solution with 7 upvotes. He has reference the parameter with an @ sign, hence I suggested you add an @ sign before your parameter valido
I hope that works for you. if it does vote up and mark it as the answer. If not, tell me.
I want to add one more answer :
It happens when you try to pass positional parameter with wrong position order along with keyword argument in calling function.
there is difference between parameter and argument
you can read in detail about here Arguments and Parameter in python
def hello(a,b=1, *args):
print(a, b, *args)
hello(1, 2, 3, 4,a=12)
since we have three parameters :
a is positional parameter
b=1 is keyword and default parameter
*args is variable length parameter
so we first assign a as positional parameter , means we have to provide value to positional argument in its position order, here order matter. but we are passing argument 1 at the place of a in calling function and then we are also providing value to a , treating as keyword argument. now a have two values :
one is positional value: a=1
second is keyworded value which is a=12
We have to change hello(1, 2, 3, 4,a=12)
to hello(1, 2, 3, 4,12)
so now a will get only one positional value which is 1 and b will get value 2 and rest of values will get *args (variable length parameter)
if we want that *args should get 2,3,4 and a should get 1 and b should get 12
then we can do like this
def hello(a,*args,b=1):
pass
hello(1, 2, 3, 4,b=12)
Something more :
def hello(a,*c,b=1,**kwargs):
print(b)
print(c)
print(a)
print(kwargs)
hello(1,2,1,2,8,9,c=12)
output :
1
(2, 1, 2, 8, 9)
1
{'c': 12}
This is a sample code I used to counter the problem.

Also note that if you want to apply an instance method to an array, you need to pass the function as:
call_user_func_array(array($instance, "MethodName"), $myArgs);
Something like:
File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);
I faced this problem when I tried to build and install my app to a Android 8.1.0 (API 26)phone.
The only reason is that I added android:hasCode="false"
to the application
tag in the manifest
file. However, it worked on API 24 with the same code when I tried several months ago (STRANGE?).
After removing that attribute, the problem disappears.
If you want to combine two files where one overlays the other (example: document A is a template and document B has the text you want to put on the template), this works:
after creating "doc", you want to write your template (templateFile) on top of that -
PDDocument watermarkDoc = PDDocument.load(getServletContext()
.getRealPath(templateFile));
Overlay overlay = new Overlay();
overlay.overlay(watermarkDoc, doc);
There is no difference. The $_SERVER['PHP_SELF'] just makes the execution time slower by like 0.000001 second.
We used to run a social website, on a standard LAMP configuration. We had a Live server, Test server, and Development server, as well as the local developers machines. All were managed using GIT.
On each machine, we had the PHP files, but also the MySQL service, and a folder with Images that users would upload. The Live server grew to have some 100K (!) recurrent users, the dump was about 2GB (!), the Image folder was some 50GB (!). By the time that I left, our server was reaching the limit of its CPU, Ram, and most of all, the concurrent net connection limits (We even compiled our own version of network card driver to max out the server 'lol'). We could not (nor should you assume with your website) put 2GB of data and 50GB of images in GIT.
To manage all this under GIT easily, we would ignore the binary folders (the folders containing the Images) by inserting these folder paths into .gitignore. We also had a folder called SQL outside the Apache documentroot path. In that SQL folder, we would put our SQL files from the developers in incremental numberings (001.florianm.sql, 001.johns.sql, 002.florianm.sql, etc). These SQL files were managed by GIT as well. The first sql file would indeed contain a large set of DB schema. We don't add user-data in GIT (eg the records of the users table, or the comments table), but data like configs or topology or other site specific data, was maintained in the sql files (and hence by GIT). Mostly its the developers (who know the code best) that determine what and what is not maintained by GIT with regards to SQL schema and data.
When it got to a release, the administrator logs in onto the dev server, merges the live branch with all developers and needed branches on the dev machine to an update branch, and pushed it to the test server. On the test server, he checks if the updating process for the Live server is still valid, and in quick succession, points all traffic in Apache to a placeholder site, creates a DB dump, points the working directory from 'live' to 'update', executes all new sql files into mysql, and repoints the traffic back to the correct site. When all stakeholders agreed after reviewing the test server, the Administrator did the same thing from Test server to Live server. Afterwards, he merges the live branch on the production server, to the master branch accross all servers, and rebased all live branches. The developers were responsible themselves to rebase their branches, but they generally know what they are doing.
If there were problems on the test server, eg. the merges had too many conflicts, then the code was reverted (pointing the working branch back to 'live') and the sql files were never executed. The moment that the sql files were executed, this was considered as a non-reversible action at the time. If the SQL files were not working properly, then the DB was restored using the Dump (and the developers told off, for providing ill-tested SQL files).
Today, we maintain both a sql-up and sql-down folder, with equivalent filenames, where the developers have to test that both the upgrading sql files, can be equally downgraded. This could ultimately be executed with a bash script, but its a good idea if human eyes kept monitoring the upgrade process.
It's not great, but its manageable. Hope this gives an insight into a real-life, practical, relatively high-availability site. Be it a bit outdated, but still followed.

This is the simplest and the correct method. All you have to do is to add this code after initComponents();
getContentPane().setBackground(new java.awt.Color(204, 166, 166));
That is an example RGB color, you can replace that with your desired color. If you dont know the codes of RGB colors, please search on internet... there are a lot of sites that provide custom colors like this.

This seems to be answered - #include <fstream>
.
The message means :-
incomplete type
- the class has not been defined with a full class. The compiler has seen statements such as class ifstream;
which allow it to understand that a class exists, but does not know how much memory the class takes up.
The forward declaration allows the compiler to make more sense of :-
void BindInput( ifstream & inputChannel );
It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.
The has initializer
seems a bit extraneous, but is saying that the incomplete object is being created.
Also use NVL2
as below if you want to return other value from the field_to_check
:
NVL2( field_to_check, value_if_NOT_null, value_if_null )

Although I am very late to this but after seeing some legitimate questions for those who wanted to use INSERT-SELECT
query with GROUP BY
clause, I came up with the work around for this.
Taking further the answer of Marcus Adams and accounting GROUP BY
in it, this is how I would solve the problem by using Subqueries in the FROM Clause
INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct,
inact, inadur, inadist,
smlct, smldur, smldist,
larct, lardur, lardist,
emptyct, emptydur)
SELECT sb.id, uid, sb.location, sb.animal, sb.starttime, sb.endtime, sb.entct,
sb.inact, sb.inadur, sb.inadist,
sb.smlct, sb.smldur, sb.smldist,
sb.larct, sb.lardur, sb.lardist,
sb.emptyct, sb.emptydur
FROM
(SELECT id, uid, location, animal, starttime, endtime, entct,
inact, inadur, inadist,
smlct, smldur, smldist,
larct, lardur, lardist,
emptyct, emptydur
FROM tmp WHERE uid=x
GROUP BY location) as sb
ON DUPLICATE KEY UPDATE entct=sb.entct, inact=sb.inact, ...
This is what I used on MAC.
Use your preferred compiler.
Compile with gcc.
gcc -lstdc++ filename.cpp -o outputName
Or Compile with clang.
clang++ filename.cpp -o outputName
After done compiling. You can run it with.
./outputFile
You can not sort TreeMap on values.
A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide
comparator
forComparator<? super K>
so your comparator should compare on keys.
To provide sort on values you will need SortedSet. Use
SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Map.Entry<String, Double> e1,
Map.Entry<String, Double> e2) {
return e1.getValue().compareTo(e2.getValue());
}
});
sortedset.addAll(myMap.entrySet());
To give you an example
SortedMap<String, Double> myMap = new TreeMap<String, Double>();
myMap.put("a", 10.0);
myMap.put("b", 9.0);
myMap.put("c", 11.0);
myMap.put("d", 2.0);
sortedset.addAll(myMap.entrySet());
System.out.println(sortedset);
Output:
[d=2.0, b=9.0, a=10.0, c=11.0]
Just use the KeepAlive like @toster-cx says and then use the Socket Connected status to check if the Socket is still connected. Set your receive timeout at the same timeout of the keepalive. If you have more questions i am always happy to help!
Although I didn't use this exact function I got this same error.
In my case I just had to remove the protocol.
Instead of $uri = "http://api.hostip.info/?ip=$ip&position=true";
Use $uri = "api.hostip.info/?ip=$ip&position=true";
And it worked fine afterwards
I found this to work very well!
function findRoot() {
return(substr($_SERVER["SCRIPT_FILENAME"], 0, (stripos($_SERVER["SCRIPT_FILENAME"], $_SERVER["SCRIPT_NAME"])+1)));
}
Use:
<?php
function findRoot() {
return(substr($_SERVER["SCRIPT_FILENAME"], 0, (stripos($_SERVER["SCRIPT_FILENAME"], $_SERVER["SCRIPT_NAME"])+1)));
}
include(findRoot() . 'Post.php');
$posts = getPosts(findRoot() . 'posts_content');
include(findRoot() . 'includes/head.php');
for ($i=(sizeof($posts)-1); 0 <= $i; $i--) {
$posts[$i]->displayArticle();
}
include(findRoot() . 'includes/footer.php');
?>
Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:
The main idea behind this is to encapsulate the text and the circle in the same "div
" as you would do in html to have the logo and the name of the company in the same div
in a page header.
The main code is:
var width = 960,
height = 500;
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
d3.json("data.json", function(json) {
/* Define the data for the circles */
var elem = svg.selectAll("g")
.data(json.nodes)
/*Create and place the "blocks" containing the circle and the text */
var elemEnter = elem.enter()
.append("g")
.attr("transform", function(d){return "translate("+d.x+",80)"})
/*Create the circle for each block */
var circle = elemEnter.append("circle")
.attr("r", function(d){return d.r} )
.attr("stroke","black")
.attr("fill", "white")
/* Create the text for each block */
elemEnter.append("text")
.attr("dx", function(d){return -20})
.text(function(d){return d.label})
})
and the json file is:
{"nodes":[
{"x":80, "r":40, "label":"Node 1"},
{"x":200, "r":60, "label":"Node 2"},
{"x":380, "r":80, "label":"Node 3"}
]}
The resulting html code shows the encapsulation you want:
<svg width="960" height="500">
<g transform="translate(80,80)">
<circle r="40" stroke="black" fill="white"></circle>
<text dx="-20">Node 1</text>
</g>
<g transform="translate(200,80)">
<circle r="60" stroke="black" fill="white"></circle>
<text dx="-20">Node 2</text>
</g>
<g transform="translate(380,80)">
<circle r="80" stroke="black" fill="white"></circle>
<text dx="-20">Node 3</text>
</g>
</svg>
First off, custom events don't play well with React components natively. So you cant just say <div onMyCustomEvent={something}>
in the render function, and have to think around the problem.
Secondly, after taking a peek at the documentation for the library you're using, the event is actually fired on document.body
, so even if it did work, your event handler would never trigger.
Instead, inside componentDidMount
somewhere in your application, you can listen to nv-enter by adding
document.body.addEventListener('nv-enter', function (event) {
// logic
});
Then, inside the callback function, hit a function that changes the state of the component, or whatever you want to do.
I had similar issue just that excel was the destination in my case instead of source as in the case of the original question/issue. I have spent hours to resolve this issue but looks like finally Soniya Parmar saved the day for me. I have set job and let it run for few iterations already and all is good now. As per her suggestion I set up the delay validation of the Excel connection manager to 'True. Thanks Soniya
Try putting
Display:inline;
In the CSS.
Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.
However it means that if you are currently using APC to store other data (through the apc_store()
function) you will not be able to do that if you decide to use OPCache.
You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.
Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.
The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:
; Sets how much memory to use
opcache.memory_consumption=128
;Sets how much memory should be used by OPcache for storing internal strings
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8
; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000
;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60
;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1
;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1
If you use any library or code that uses code annotations you must enable save comments:
opcache.save_comments=1
If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)
In javascript:
var str = "abcdaaaaaabcdaabbccddabcd";
document.write(str.replace(/(abcd)/g,"----"));
//example output: ----aaaaa----aabbccdd----
In other languages, it would be something similar. Remember to enable global matches.
There is another way to disable JPA tools for the project, that doesn't require to uninstall JPA features/plug-ins. I tested on https://github.com/Jasig/uPortal project wich was mentioned in https://bugs.eclipse.org/bugs/show_bug.cgi?id=386171 and claims to have similar problems:
After disabling JPA facet for uportal-war project form repository above I don't see any JPA related jobs in Eclipse Progress View.
In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.olddirectory"
android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
</Preference>
</PreferenceScreen>
I needed the following instead:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.newdirectory"
android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>
Correcting the path names fixed the problem.
I suggest to use ReactiveProperty. This is the shortest method except Fody.
public class Data : INotifyPropertyChanged
{
// boiler-plate
...
// props
private string name;
public string Name
{
get { return name; }
set { SetField(ref name, value, "Name"); }
}
}
instead
public class Data
{
// Don't need boiler-plate and INotifyPropertyChanged
// props
public ReactiveProperty<string> Name { get; } = new ReactiveProperty<string>();
}

I use Google Docs embeddable PDF viewer. The docs don't have to be uploaded to Google Docs, but they do have to be available online.

The following works for me on Snow Leopard:
Runtime rt = Runtime.getRuntime();
String[] testArgs = {"touch", "TEST"};
rt.exec(testArgs);
Thing is, if you want to read the output of that command, you need to read the input stream of the process. For instance,
Process pr = rt.exec(arguments);
BufferedReader r = new BufferedReader(new InputStreamReader(pr.getInputStream()));
Allows you to read the line-by-line output of the command pretty easily.
The problem might also be that MS-DOS does not interpret your order of arguments to mean "start a new command prompt". Your array should probably be:
{"start", "cmd.exe", "\c"}
To open commands in the new command prompt, you'd have to use the Process reference. But I'm not sure why you'd want to do that when you can just use exec, as the person before me commented.
When peer close, you just do not know whether it just stop sending or both sending and receiving.Because TCP allows this, btw, you should know the difference between close and shutdown. If peer both stop sending and receiving, first you send some bytes, it will succeed. But the peer kernel will send you RST. So subsequently you send some bytes, your kernel will send you SIGPIPE signal, if you catch or ignore this signal, when your send returns, you just get Broken pipe error, or if you don't , the default behavior of your program is crashing.

The answer is, "No."
What C programmers do is store the size of the array somewhere. It can be part of a structure, or the programmer can cheat a bit and malloc()
more memory than requested in order to store a length value before the start of the array.
try this, I am sure this will work for you.

If your <div>
has position: absolute
you need to use width: 100%;
#parent {
width: 100%;
text-align: center;
}
#child {
display: inline-block;
}
I have what i think is a better solution, since it is scalable to more levels, as many as wanted, not only two or three.
I use borders, but it can also be done with whateever style wanted, like background-color.
With the border, the idea is to:
You can test it at: http://jsbin.com/ubiyo3/13

As per the comment by drris, if IsBodyHtml
is set to true then a standard newline could potentially be ignored by design, I know you mention avoiding HTML but try using <br />
instead, even if just to see if this 'solves' the problem - then you can rule out by what you know:
var message = new System.Net.Mail.MailMessage();
message.Body = "First Line <br /> second line";
You may also just try setting IsBodyHtml
to false
and determining if newlines work in that instance, although, unless you set it to true
explicitly I'm pretty sure it defaults to false
anyway.
Also as a side note, avoiding HTML in emails is not necessarily any aid in getting the message through spam filters, AFAIK - if anything, the most you do by this is ensure cross-mail-client compatibility in terms of layout. To 'play nice' with spam filters, a number of other things ought to be taken into account; even so much as the subject and content of the mail, who the mail is sent from and where and do they match et cetera. An email simply won't be discriminated against because it is marked up with HTML.
Working with POST in webapi can be tricky! Would like to add to the already correct answer..
Will focus specifically on POST as dealing with GET is trivial. I don't think many would be searching around for resolving an issue with GET with webapis. Anyways..
If your question is - In MVC Web Api, how to- - Use custom action method names other than the generic HTTP verbs? - Perform multiple posts? - Post multiple simple types? - Post complex types via jQuery?
Then the following solutions may help:
First, to use Custom Action Methods in Web API, add a web api route as:
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "api/{controller}/{action}");
}
And then you may create action methods like:
[HttpPost]
public string TestMethod([FromBody]string value)
{
return "Hello from http post web api controller: " + value;
}
Now, fire the following jQuery from your browser console
$.ajax({
type: 'POST',
url: 'http://localhost:33649/api/TestApi/TestMethod',
data: {'':'hello'},
contentType: 'application/x-www-form-urlencoded',
dataType: 'json',
success: function(data){ console.log(data) }
});
Second, to perform multiple posts, It is simple, create multiple action methods and decorate with the [HttpPost] attrib. Use the [ActionName("MyAction")] to assign custom names, etc. Will come to jQuery in the fourth point below
Third, First of all, posting multiple SIMPLE types in a single action is not possible. Moreover, there is a special format to post even a single simple type (apart from passing the parameter in the query string or REST style). This was the point that had me banging my head with Rest Clients (like Fiddler and Chrome's Advanced REST client extension) and hunting around the web for almost 5 hours when eventually, the following URL proved to be of help. Will quote the relevant content for the link might turn dead!
Content-Type: application/x-www-form-urlencoded
in the request header and add a = before the JSON statement:
={"Name":"Turbo Tina","Email":"[email protected]"}
PS: Noticed the peculiar syntax?
http://forums.asp.net/t/1883467.aspx?The+received+value+is+null+when+I+try+to+Post+to+my+Web+Api
Anyways, let us get over that story. Moving on:
Fourth, posting complex types via jQuery, ofcourse, $.ajax() is going to promptly come in the role:
Let us say the action method accepts a Person object which has an id and a name. So, from javascript:
var person = { PersonId:1, Name:"James" }
$.ajax({
type: 'POST',
url: 'http://mydomain/api/TestApi/TestMethod',
data: JSON.stringify(person),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function(data){ console.log(data) }
});
And the action will look like:
[HttpPost]
public string TestMethod(Person person)
{
return "Hello from http post web api controller: " + person.Name;
}
All of the above, worked for me!! Cheers!
Using regex:
str = 'string'
n = 2 #to remove last n characters
str[/\A.{#{str.size-n}}/] #=> "stri"
Those are hexidecimal digits, not characters. One digit = 4 bits.
Regarding the performance of a many-to-many table, if you have 2 32-bit ints linking user IDs, your basic data storage for 200,000,000 users averaging 200 friends apiece is just under 300GB.
Obviously, you would need some partitioning and indexing and you're not going to keep that in memory for all users.
I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:
multiDexEnabled true
And it worked!
Example
android {
compileSdkVersion 27
buildToolsVersion '27.0.1'
defaultConfig {
applicationId "com.xx.xxx"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
multiDexEnabled true //Add this
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
And clean the project.
I know its been a while since the original post but I like using CTE's and this worked for me:
WITH cte_table_a
AS
(
SELECT [id] [id]
, MAX([value]) [value]
FROM table_a
GROUP BY [id]
)
UPDATE table_b
SET table_b.code = CASE WHEN cte_table_a.[value] IS NOT NULL THEN cte_table_a.[value] ELSE 124 END
FROM table_b
LEFT OUTER JOIN cte_table_a
ON table_b.id = cte_table_a.id
In C# it also works with a null as the 4th parameter.
@Html.ActionLink( "Front Page", "Index", "Home", null, new { @class = "MenuButtons" })
I had this problem as well.
My problem was that I had copy/pasted the library include directories from my debug configurations.
So project "Indep" was including static library "Dep.lib" from "../Debug", even in release. The fix was to change the library directory to "../Release" so I caught the release-built library rather than the previously-built debug library.
I just did this for fun
>>> s = 'a,b,c,d'
>>> [item[::-1] for item in s[::-1].split(',', 1)][::-1]
['a,b,c', 'd']
Caution: Refer to the first comment in below where this answer can go wrong.
Identify "project navigator"
or "package explorer"
view.
Right click on your project, select Build Path --> Configure build Path
.
In the emerging window, you will find four tabs, select "Libraries"
.There, under "Web app libraries"
(expand it), you will see the libraries added to the project's classpath. Check if all of them are available. If one or more are not (they'll have "missing" beside their name and a red mark on their icon), check if you need them (perhaps you don't); if you don't need them, remove it, if you need them, exit this window, look out for the missing jar and IMPORT it into your project.
Use chrome.tabs.query()
like this:
chrome.tabs.query({active: true, lastFocusedWindow: true}, tabs => {
let url = tabs[0].url;
// use `url` here inside the callback because it's asynchronous!
});
This requires that you request access to the chrome.tabs
API in your extension manifest:
"permissions": [ ...
"tabs"
]
It's important to note that the definition of your "current tab" may differ depending on your extension's needs.
Setting lastFocusedWindow: true
in the query is appropriate when you want to access the current tab in the user's focused window (typically the topmost window).
Setting currentWindow: true
allows you to get the current tab in the window where your extension's code is currently executing. For example, this might be useful if your extension creates a new window / popup (changing focus), but still wants to access tab information from the window where the extension was run.
I chose to use lastFocusedWindow: true
in this example, because Google calls out cases in which currentWindow
may not always be present.
You are free to further refine your tab query using any of the properties defined here: chrome.tabs.query
Try using the below syntax:
Common Syntax:
begin
dbms_mview.refresh('mview_name');
end;
Example:
begin
dbms_mview.refresh('inv_trans');
end;
Hope the above helps.
pip list
List installed packages: show ALL installed packages that even pip installed implictly
pip freeze
List installed packages: - list of packages that are installed using pip command
pip freeze has --all
flag to show all the packages.
Other difference is the output it renders, that you can check by running the commands.
For Windows
I had the same problem, I tried to reinstall and didn't worked for me.
Remove "C:\Program Files(x86)\nodejs"
from your system enviorment PATH
and thats it!
It depends on the Test Construct around the operator. Your options are double parentheses, double brackets, single brackets, or test
.
If you use ((
…))
, you are testing arithmetic equality with ==
as in C:
$ (( 1==1 )); echo $?
0
$ (( 1==2 )); echo $?
1
(Note: 0
means true
in the Unix sense and a failed test results in a non-zero number.)
Using -eq
inside of double parentheses is a syntax error.
If you are using [
…]
(or single brackets) or [[
…]]
(or double brackets), or test
you can use one of -eq
, -ne
, -lt
, -le
, -gt
, or -ge
as an arithmetic comparison.
$ [ 1 -eq 1 ]; echo $?
0
$ [ 1 -eq 2 ]; echo $?
1
$ test 1 -eq 1; echo $?
0
The ==
inside of single or double brackets (or the test
command) is one of the string comparison operators:
$ [[ "abc" == "abc" ]]; echo $?
0
$ [[ "abc" == "ABC" ]]; echo $?
1
As a string operator, =
is equivalent to ==
. Also, note the whitespace around =
or ==
: it’s required.
While you can do [[ 1 == 1 ]]
or [[ $(( 1+1 )) == 2 ]]
it is testing the string equality — not the arithmetic equality.
So -eq
produces the result probably expected that the integer value of 1+1
is equal to 2
even though the right-hand side is a string and has a trailing space:
$ [[ $(( 1+1 )) -eq "2 " ]]; echo $?
0
While a string comparison of the same picks up the trailing space and therefore the string comparison fails:
$ [[ $(( 1+1 )) == "2 " ]]; echo $?
1
And a mistaken string comparison can produce a completely wrong answer. 10
is lexicographically less than 2
, so a string comparison returns true
or 0
. So many are bitten by this bug:
$ [[ 10 < 2 ]]; echo $?
0
The correct test for 10
being arithmetically less than 2
is this:
$ [[ 10 -lt 2 ]]; echo $?
1
In comments, there is a question about the technical reason why using the integer -eq
on strings returns true for strings that are not the same:
$ [[ "yes" -eq "no" ]]; echo $?
0
The reason is that Bash is untyped. The -eq
causes the strings to be interpreted as integers if possible including base conversion:
$ [[ "0x10" -eq 16 ]]; echo $?
0
$ [[ "010" -eq 8 ]]; echo $?
0
$ [[ "100" -eq 100 ]]; echo $?
0
And 0
if Bash thinks it is just a string:
$ [[ "yes" -eq 0 ]]; echo $?
0
$ [[ "yes" -eq 1 ]]; echo $?
1
So [[ "yes" -eq "no" ]]
is equivalent to [[ 0 -eq 0 ]]
Last note: Many of the Bash specific extensions to the Test Constructs are not POSIX and therefore may fail in other shells. Other shells generally do not support [[...]]
and ((...))
or ==
.
Use this Code in code behind
Div_Card.Style["background-image"] = Page.ResolveUrl(Session["Img_Path"].ToString());
The EXTRA_ALLOW_MULTIPLE option is set on the intent through the Intent.putExtra() method:
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
Your code above should look like this:
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);
Note: the EXTRA_ALLOW_MULTIPLE
option is only available in Android API 18 and higher.

Solution who works with Lumen 5.5 with foreign keys constraints :

i am using the following method to get the caller for a specific class from the stacktrace:
package test.log;
public class CallerClassTest {

final Caller caller = new Caller(new Callee());
caller.execute();
}
private static class Caller {
private final Callee c;

}
void execute() {
c.call();

void call() {
System.out.println(getCallerClassName(this.getClass()));
}
}
/**

* calling class could not be found.
*
* @param clazz

for (int i = 1; i < stackTrace.length; i++) {
final StackTraceElement element = stackTrace[i];

android:editable="false"
should work, but it is deprecated, you should be using android:inputType="none"
instead.
Alternatively, if you want to do it in the code you could do this :
EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);
This is also a viable alternative :
EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);
If you're going to make your EditText
non-editable, may I suggest using the TextView
widget instead of the EditText
, since using a EditText seems kind of pointless in that case.
EDIT: Altered some information since I've found that android:editable
is deprecated, and you should use android:inputType="none"
, but there is a bug about it on android code; So please check this.
I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.
SET @sql = '';
SELECT
@sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
SELECT
DISTINCT
CONCAT(
'MAX(IF(pa.fieldname = ''',
fieldname,
''', pa.fieldvalue, NULL)) AS ',
fieldname
) as output
FROM
product_additional
) as temp;
SET @sql = CONCAT('SELECT p.id
, p.name
, p.description, ', @sql, '
FROM product p
LEFT JOIN product_additional AS pa
ON p.id = pa.id
GROUP BY p.id');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
ActionListener gets fired first, with an option to modify the response, before Action gets called and determines the location of the next page.
If you have multiple buttons on the same page which should go to the same place but do slightly different things, you can use the same Action for each button, but use a different ActionListener to handle slightly different functionality.
Here is a link that describes the relationship:
I think this code is short and clear:
int id;
String name;
JSONArray array = new JSONArray(string_of_json_array);
for (int i = 0; i < array.length(); i++) {
JSONObject row = array.getJSONObject(i);
id = row.getInt("id");
name = row.getString("name");
}
Is that what you were looking for?
Works for me
sudo chmod -R g+rwX .
Although "Mark Circular Dependencies" enables you to compile the code, it may lead to a slower environment and future issues.
That's happening because at some point Eclipse has lost it's directions on your build path.
1 - Remove the project and it's references from the workspace. 2 - Import it back again. 3 - Check the references.
It is the best solution.
Example: Display different output depending on whether the user is logged in or not.
<?php
if ( is_user_logged_in() ) {
echo 'Welcome, registered user!';
} else {
echo 'Welcome, visitor!';
}
?>

Try the snipped which is mentioned below, it works for me also.
In my layout xml
where I have my TabLayout
, have added style to the TabLayout
like below :
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
style="@style/MyCustomTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed" />
and in my style.xml
I have defined the style that is used in my layout xml, check code for styles added below :
<style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
<item name="android:background">YOUR BACKGROUND COLOR</item>
<item name="tabTextAppearance">@style/MyCustomTabText</item>
<item name="tabSelectedTextColor">SELECTED TAB TEXT COLOR</item>
<item name="tabIndicatorColor">SELECTED TAB INDICATOR COLOR</item>
</style>
<style name="MyCustomTabText" parent="TextAppearance.AppCompat.Button">
<item name="android:textSize">YOUR TEXT SIZE</item>
<item name="android:textStyle">bold</item>
<item name="android:textColor">@android:color/white</item>
</style>
I hope it will work for you.....
require_once('../web/a.php');
If this is not working for anyone, following is the good Idea to include file anywhere in the project.
require_once dirname(__FILE__)."/../../includes/enter.php";
This code will get the file from 2 directory outside of the current directory.
In terms of pattern interpretation, there's no difference between the following forms:
/pattern/
new RegExp("pattern")
If you want to replace a literal string using the replace
method, I think you can just pass a string instead of a regexp to replace
.
Otherwise, you'd have to escape any regexp special characters in the pattern first - maybe like so:
function reEscape(s) {
return s.replace(/([.*+?^$|(){}\[\]])/mg, "\\$1");
}
// ...
var re = new RegExp(reEscape(pattern), "mg");
this.markup = this.markup.replace(re, value);
Take a look at jsHybugger. It will allow you to remotely debug your js code for:
How this works (more details and alternatives on the projects site, this was what I found to be the best way).
Again, with Chrome on Android use the ADB extension without jsHybugger. I think this already described in the accepted answer to this question.
It is an old question but a common one. So let me add this one here.
With arrow function syntax you can achieve it more succinct way since it is lexically binded and can be chained.
An arrow function expression is a syntactically compact alternative to a regular function expression, although without its own bindings to the this, arguments, super, or new.target keywords.
const event_handler = (event, arg) => console.log(event, arg);
el.addEventListener('click', (event) => event_handler(event, 'An argument'));
If you need to clean up the event listener:
// Let's use use good old function sytax
function event_handler(event, arg) {
console.log(event, arg);
}
// Assign the listener callback to a variable
var doClick = (event) => event_handler(event, 'An argument');
el.addEventListener('click', doClick);
// Do some work...
// Then later in the code, clean up
el.removeEventListener('click', doClick);
Here is crazy one-liner:
// You can replace console.log with some other callback function
el.addEventListener('click', (event) => ((arg) => console.log(event, arg))('An argument'));
More docile version: More appropriate for any sane work.
el.addEventListener('click', (event) => ((arg) => {
console.log(event, arg);
})('An argument'));
This is the bad practice but you can use this technique to close modal by calling close button in javascript. This will close modal after 3 seconds.

This is a broad question and there are multiple ways you can achieve this. In my experience, I've seen a lot of single page applications having an entry point file such as index.js
. This file would be responsible for 'bootstrapping' the application and will be your entry point for webpack.
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import Application from './components/Application';
const root = document.getElementById('someElementIdHere');
ReactDOM.render(
<Application />,
root,
);
Your <Application />
component would contain the next pieces of your app. You've stated you want different pages and that leads me to believe you're using some sort of routing. That could be included into this component along with any libraries that need to be invoked on application start. react-router
, redux
, redux-saga
, react-devtools
come to mind. This way, you'll only need to add a single entry point into your webpack configuration and everything will trickle down in a sense.
When you've setup a router, you'll have options to set a component to a specific matched route. If you had a URL of /about
, you should create the route in whatever routing package you're using and create a component of About.js
with whatever information you need.
Try width: max-content
to adjust the width of the div by it's content.

border: 3px solid #73AD21;

div.ex2 {

<div class="ex1">This div element has width 500px;</div>

I guess you're using MySQL
.
mysql_fetch_array($result);
And make sure $result
is not empty.
You can also use Select-Object like so:
Get-ChildItem "C:\WINDOWS\System32" *.txt -Recurse | Select-Object FullName
Those GCD functions provided by Commons-Math and Guava have some differences.

I would like to add another Bootstrap 4 solution. One that worked for me.
The CSS "Order" property, combined with a media query, can be used to re-order columns when they get stacked in smaller screens.
Something like this:
@media only screen and (max-width: 768px) {
#first {
order: 2;
}
#second {
order: 4;
}
#third {
order: 1;
}
#fourth {
order: 3;
}
}
CodePen Link: https://codepen.io/preston206/pen/EwrXqm
Adjust the screen size and you'll see the columns get stacked in a different order.
I'll tie this in with the original poster's question. With CSS, the navbar, sidebar, and content can be targeted and then order properties applied within a media query.
Instead use window.open()
:
The syntax is:
window.open(strUrl, strWindowName[, strWindowFeatures]);
Your code should have:
window.open('Prosjektplan.pdf');
Your code should be:
<p class="downloadBoks"
onclick="window.open('Prosjektplan.pdf')">Prosjektbeskrivelse</p>
[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*
This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.
Look at this example:
public void RunWorker()
{
Thread newThread = new Thread(WorkerMethod);
newThread.Start(new Parameter());
}
public void WorkerMethod(object parameterObj)
{
var parameter = (Parameter)parameterObj;
// do your job!
}
You are first creating a thread by passing delegate to worker method and then starts it with a Thread.Start method which takes your object as parameter.
So in your case you should use it like this:
Thread thread = new Thread(download);
thread.Start(filename);
But your 'download' method still needs to take object, not string as a parameter. You can cast it to string in your method body.
I've read your answers and made a mix. It seems to work with Windows XP(IE7/IE8) and Windows 7 (IE9/IE10/IE11).
function ie_ver(){
var iev=0;
var ieold = (/MSIE (\d+\.\d+);/.test(navigator.userAgent));
var trident = !!navigator.userAgent.match(/Trident\/7.0/);
var rv=navigator.userAgent.indexOf("rv:11.0");
if (ieold) iev=new Number(RegExp.$1);
if (navigator.appVersion.indexOf("MSIE 10") != -1) iev=10;
if (trident&&rv!=-1) iev=11;
return iev;
}
Of course if I return 0, means no IE.
On Unix-based systems, use the wc
command on the command-line.
func.__code__.co_argcount
gives you number of any arguments BEFORE *args
func.__kwdefaults__
gives you a dict of the keyword arguments AFTER *args
func.__code__.co_kwonlyargcount
is equal to len(func.__kwdefaults__)
func.__defaults__
gives you the values of optional arguments that appear before *args
Here is the simple illustration:
>>> def a(b, c, d, e, f=1, g=3, h=None, *i, j=2, k=3, **L):
pass
>>> a.__code__.co_argcount
7
>>> a.__defaults__
(1, 3, None)
>>> len(a.__defaults__)
3
>>>
>>>
>>> a.__kwdefaults__
{'j': 2, 'k': 3}
>>> len(a.__kwdefaults__)
2
>>> a.__code__.co_kwonlyargcount
