The email in the profile can be obtained using extended permission but I Guess it's not possible to get the email used to login fb. In my app i wanted to display mulitple fb accounts of a user in a list, i wanted to show the login emails of fb accounts as a unique identifier of the respective accounts but i couldn't get it off from fb, all i got was the primary email in the user profile but in my case my login email and my primary email are different.
I researched Graph API Explorer extensively and finally found full_picture
https://graph.facebook.com/v2.2/$id/posts?fields=picture,full_picture
P.S. I noticed that full_picture won't always provide full size image I want. 'attachments' does
https://graph.facebook.com/v2.2/$id/posts?fields=picture,full_picture,attachments
You can use the https://graph.facebook.com/v3.0/{Place_your_Page_ID here}/feed?fields=id,shares,share_count&access_token={Place_your_access_token_here} to get the shares count.
//create the url
$profile_pic = "http://graph.facebook.com/".$uid."/picture";
//echo the image out
echo "<img src=\"" . $profile_pic . "\" />";
Works fine for me
I ran into the same issue and then I noticed that I had a different domain for the og:url
Once I made sure that the domain was the same for og:url
and og:image
it worked.
Hope this helps.
The documentation for this is good if not a little difficult to find.
Facebook Graph API - Page Tokens
After initializing node's fbgraph, you can run:
var facebookAccountID = yourAccountIdHere
graph
.setOptions(options)
.get(facebookAccountId + "/accounts", function(err, res) {
console.log(res);
});
and receive a JSON response with the token you want to grab, located at:
res.data[0].access_token
The list from 2020-05-23 is:
31.13.24.0/21
31.13.64.0/18
45.64.40.0/22
66.220.144.0/20
69.63.176.0/20
69.171.224.0/19
74.119.76.0/22
102.132.96.0/20
103.4.96.0/22
129.134.0.0/16
147.75.208.0/20
157.240.0.0/16
173.252.64.0/18
179.60.192.0/22

185.89.216.0/22
199.201.64.0/22
204.15.20.0/22
The method to fetch this list is already documented on Facebook's Developer site, you can make a whois call to see all IPs assigned to Facebook:
whois -h whois.radb.net -- '-i origin AS32934' | grep ^route
Adding gem 'certified', '~> 1.0'
to my Gemfile
and running bundle
solved this issue for me.
The reject
actually takes one parameter: that's the exception that occurred in your code that caused the promise to be rejected. So, when you call reject()
the exception value is undefined
, hence the "undefined" part in the error that you get.
You do not show the code that uses the promise, but I reckon it is something like this:
var promise = doSth();
promise.then(function() { doSthHere(); });
Try adding an empty failure call, like this:
promise.then(function() { doSthHere(); }, function() {});
This will prevent the error to appear.
However, I would consider calling reject
only in case of an actual error, and also... having empty exception handlers isn't the best programming practice.
Try This url with valid userid and access token:
https://graph.facebook.com/{userid}/photos?limit=20&access_token={access_token}
Facebook.com og:image is 325x325 (1:1 aspect ratio, square)
It might help somebody.
I had the similar error message, but only in dev and staging environments, not in production. The valid redirect URIs were correctly set, for the dev and staging subdomains as well as for production.
It turned out I forgot that for those environments we use the testing FB app, which is a separate one in the FB developer page. Had to select that and update its settings.
Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.
I had this issue today, I find the Facebook documentation and SDK disrespectful and arogant towards other developers to say the least.
Besides having the "app domains" in two different locations without much information (3 if you add a "web" platform), you also need to go to app products / facebook login / settings and add your redirect URL under Valid OAuth Redirect URIs
The error says NOTHING about the oauth settings.
For Angular:
getUserPicture(userId) {
FB.api('/' + userId, {fields: 'picture.width(800).height(800)'}, function(response) {
console.log('getUserPicture',response);
});
}
I just encountered this problem myself. I'm developing an app internally, so my host is 'localhost'. It wasn't obvious how to set 'localhost' up in the app configuration. If you want to develop locally, set up your app by following these steps:
Save and wait a couple of minutes for the information to propagate, although it worked right away for me.
No, this isn't possible. In order for you to send messages of any kind to a Facebook user, you need that user's permission to do so.
If someone logs into your site with Facebook Connect, they are explicitly agreeing to share their Facebook data with your site, and you will then be able to send that person a message through the normal channels. You would also be able to fetch their friend list. However, you can not send messages to the friends.
I think the documentation is reasonably helpful!
If you read it again, it says that adding open graph elements on your website will make your website act as a facebook page and you'll get the ability to publish updates to them etc.
So I think it's up to you - you can either just have a page with no OG elements, which is less work but also less 'rewarding' for you.
If you do use og, then set type to: blog
Finally: fb:admins
or fb:app_id
- A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.
So just put your own fbid in there. As a tip, you can easily get this by looking at the url of your profile photo on facebook.
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission). This has been confirmed by Facebook as 'by design'.
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.
I found this answer which refers to this tool which really helped a lot.
I hope this answer is still valid when you read this.
The easiest way is
https://graph.facebook.com/me?fields=id&access_token="xxxxx"
then you will get json response which contains only userid.
Facebook Developer Wiki (unofficial) contain not only list of FQL error codes but others too it's somehow updated but not contain full list of possible error codes.
There is no any official or updated (I mean really updated) list of error codes returned by Graph API. Every list that can be found online is outdated and not help that much...
There is official list describing some of API Errors and basic recovery tactics. Also there is couple of offcial lists for specific codes:
I tore my hair out over this one too. Your code only works if the user has granted an extended permission for that which is not ideal.
In a nutshell, if you turn on the OAuth 2.0
for Canvas advanced option, Facebook will send a $_REQUEST['signed_request']
along with every page requested within your tab app. If you parse that signed_request you can get some info about the user including if they've liked the page or not.
function parsePageSignedRequest() {
if (isset($_REQUEST['signed_request'])) {
$encoded_sig = null;
$payload = null;
list($encoded_sig, $payload) = explode('.', $_REQUEST['signed_request'], 2);
$sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
$data = json_decode(base64_decode(strtr($payload, '-_', '+/'), true));
return $data;
}
return false;
}
if($signed_request = parsePageSignedRequest()) {
if($signed_request->page->liked) {
echo "This content is for Fans only!";
} else {
echo "Please click on the Like button to view this tab!";
}
}
This is the code as 2017:
<i class="fa fa-facebook-square"></i>
<a href="#" onclick="window.open('https://www.facebook.com/sharer/sharer.php?u='+encodeURIComponent(location.href),'facebook-share-dialog','width=626,height=436');return false;">Share on Facebook</a>
Facebook now takes all data from OG metatags.
NOTE: This code assumes you have OG metatags on in site's code.
The Facebook "Graph API Rate Limiting" docs says that an error with code #4
is an app level rate limit, which is different than user level rate limits. Although it doesn't give any exact numbers, it describes their app level rate-limit as:
This rate limiting is applied globally at the app level. Ads api calls are excluded.
- Rate limiting happens real time on sliding window for past one hour.
- Stats is collected for number of calls and queries made, cpu time spent, memory used for each app.
- There is a limit for each resource multiplied by monthly active users of a given app.
- When the app uses more than its allowed resources the error is thrown.
- Error, Code: 4, Message: Application request limit reached
The docs also give recommendations for avoiding the rate limits. For app level limits, they are:
Recommendations:
- Verify the error code (4) to confirm the throttling type.
- Do not make burst of calls, spread out the calls throughout the day.
- Do smart fetching of data (important data, non duplicated data, etc).
- Real-time insights, make sure API calls are structured in a way that you can read insights for as many as Page posts as possible, with minimum number of requests.
- Don't fetch users feed twice (in the case that two App users have a specific friend in common)
- Don't fetch all user's friends feed in a row if the number of friends is more than 250. Separate the fetches over different days. As an option, fetch first the app user's news feed (me/home) in order to detect which friends are more important to the App user. Then, fetch those friends feeds first.
- Consider to limit/filter the requests by using the following parameters: "since", "until", "limit"
- For page related calls use realtime updates to subscribe to changes in data.
- Field expansion allows ton "join" multiple graph queries into a single call.
- Etags to check if the data querying has changed since the last check.
- For page management developers who does not have massive user base, have the admins of the page to accept the app to increase the number of users.
Finally, the docs give the following informational tips:
- Batching calls will not reduce the number of api calls.
- Making parallel calls will not reduce the number of api calls.
This error also occurs when you try to log in in your test version of the Facebook app and you have not added the user you are trying to test the log in with in the Roles -> Testers section.
To fix it, just add the email address of the Facebook account you are trying to log in with in the section above.
Finally, make sure the user you added accepts the request sent before you try to test otherwise the log in process will fail in the second screen just after the user accept the conditions.
I had also faced the same issue in which my FB app was automatically stopped and users were not able to login and were getting the message "app is in development mode.....".
Reason why FB automatically stopped my app was that I had not provided a valid PRIVACY policy & terms URL. So, make sure you enter these URLs on your app basic settings page and then make your app PUBLIC from app review page as described in above posts.
This page https://developers.facebook.com/docs/reference/fql/like/ wrote, you can't get fan list.
"The Post, Video, Note, Link, Photo and Album Graph API objects contain an equivalent connection called likes."
NOTE: fql like query is deprecated
You can use AngularJs for this, Its two -way data binding feature will get solution with minimum effort and less code.
<div>
<input type="text" name="" ng-model="fbid"><br/>
<img src="https://graph.facebook.com/{{fbid}}/picture?type=normal">
</div>
I hope this answers your query.Note: You can use other library as well.
Since Facebook's Android SDK v4.0 (see changelog) you need to execute the following:
LoginManager.getInstance().logOut();
For graph API v2.1, you can get the like count using 1 call only and, therefore, no need to go through the paging.
For example, to get the number of likes of http://www.imdb.com
https://graph.facebook.com/414652589771/likes?summary=1
Graph API Explorer https://developers.facebook.com/tools/explorer/?method=GET&path=414652589771%2Flikes%3Fsummary%3D1&version=v2.1
It is somehow not documented (at least at the moment I submit this answer...). I found the answer in https://stackoverflow.com/a/18198957/1822624
The function expects a string.
file_exists()
does not work properly with HTTP URLs.
=IF(X2>=85,0.559,IF(X2>=80,0.327,IF(X2>=75,0.255,-1)))
Explanation:
=IF(X2>=85, 'If the value is in the highest bracket
0.559, 'Use the appropriate number
IF(X2>=80, 'Otherwise, if the number is in the next highest bracket
0.327, 'Use the appropriate number
IF(X2>=75, 'Otherwise, if the number is in the next highest bracket
0.255, 'Use the appropriate number
-1 'Otherwise, we're not in any of the ranges (Error)
)
)
)
You need to use padding on the list item layout so space is added on the edges of the item (just increasing the font size won't do that).
<?xml version="1.0" encoding="utf-8"?>
<TextView android:id="@+id/text1"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="8dp" />
cell.imageView.image = [UIImage imageNamed:@"image.png"];
UPDATE: Like Steven Fisher said, this should only work for cells with style UITableViewCellStyleDefault which is the default style. For other styles, you'd need to add a UIImageView to the cell's contentView.
Try this
console.log(moment().format("MM ddd, YYYY HH:mm:ss a"));
console.log(moment().format("MM ddd, YYYY hh:mm:ss a"));

They behave the same but toString
also provides a way to convert a number binary, octal, or hexadecimal strings:
Example:
var a = (50274).toString(16) // "c462"
var b = (76).toString(8) // "114"
var c = (7623).toString(36) // "5vr"
var d = (100).toString(2) // "1100100"
I think, it is redundant. rs.getObject("ID_PARENT")
should return an Integer
object or null
, if the column value actually was NULL
. So it should even be possible to do something like:
if (rs.next()) {
Integer idParent = (Integer) rs.getObject("ID_PARENT");
if (idParent != null) {
iVal = idParent; // works for Java 1.5+
} else {
// handle this case
}
}
ExcelApp.Sheets[1].Range[ExcelApp.Sheets[1].Cells[1, 1], ExcelApp.Sheets[1].Cells[70, 15]].Cells.HorizontalAlignment =
Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
This works fine for me.
Because the second element is null after you clear the list.
Use:
String s = myList.get(0);
And remember, index 0 is the first element.
Lets say your company makes 4 different products, your client has another 3 different products from another 3 different companies.
Someday the client thought, why don't we integrate all our systems into one huge system. Ten minutes later their IT department said that will take 2 years.
You (the wise developer) said, why don't we just integrate all the different systems and make them work together in a homogeneous environment? The client manager staring at you... You continued, we will use a Middleware, we will study the Inputs/Outputs of all different systems, the resources they use and then choose an appropriate Middleware framework.
Still explaining to the non tech manager
With Middleware framework in the middle, the first system will produce X stuff, the system Y and Z would consume those outputs and so on.

My favorite method uses cv2.copyMakeBorder with no border, like so.
copy = cv2.copyMakeBorder(original,0,0,0,0,cv2.BORDER_REPLICATE)
First convert to p12:
openssl pkcs12 -export -in [filename-certificate] -inkey [filename-key] -name [host] -out [filename-new-PKCS-12.p12]
Create new JKS from p12:
keytool -importkeystore -deststorepass [password] -destkeystore [filename-new-keystore.jks] -srckeystore [filename-new-PKCS-12.p12] -srcstoretype PKCS12
Other way to get the minor version is:
SELECT extversion
FROM pg_catalog.pg_extension
WHERE extname='postgis'
You can open the ".git" directory and then edit the "config" file. Under "[core]" set, set "ignorecase = true" and you are done ;)
Assuming you got it from https://curl.haxx.se/download.html, just unzip it wherever you want. No need to install. If you are going to use SSL, you need to download the OpenSSL DLLs, available from curl's website.

Reading an html page with urllib is fairly simple to do. Since you want to read it as a single string I will show you.
Import urllib.request:
#!/usr/bin/python3.5
import urllib.request
Prepare our request
request = urllib.request.Request('http://www.w3schools.com')
Always use a "try/except" when requesting a web page as things can easily go wrong. urlopen() requests the page.
try:
response = urllib.request.urlopen(request)
except:
print("something wrong")
Type is a great function that will tell us what 'type' a variable is. Here, response is a http.response object.
print(type(response))
The read function for our response object will store the html as bytes to our variable. Again type() will verify this.
htmlBytes = response.read()
print(type(htmlBytes))
Now we use the decode function for our bytes variable to get a single string.
htmlStr = htmlBytes.decode("utf8")
print(type(htmlStr))
If you do want to split up this string into separate lines, you can do so with the split() function. In this form we can easily iterate through to print out the entire page or do any other processing.
htmlSplit = htmlStr.split('\n')
print(type(htmlSplit))
for line in htmlSplit:
print(line)
Hopefully this provides a little more detailed of an answer. Python documentation and tutorials are great, I would use that as a reference because it will answer most questions you might have.

They are pretty much well explained in detail in the open group documentation:
In C and C++, \n
is a concept, \r
is a character, and \r\n
is (almost always) a portability bug.
Think of an old teletype. The print head is positioned on some line and in some column. When you send a printable character to the teletype, it prints the character at the current position and moves the head to the next column. (This is conceptually the same as a typewriter, except that typewriters typically moved the paper with respect to the print head.)
When you wanted to finish the current line and start on the next line, you had to do two separate steps:
ASCII encodes these actions as two distinct control characters:
\x0D
(CR) moves the print head back to the beginning of the line. (Unicode encodes this as U+000D CARRIAGE RETURN
.)\x0A
(LF) moves the print head down to the next line. (Unicode encodes this as U+000A LINE FEED
.)In the days of teletypes and early technology printers, people actually took advantage of the fact that these were two separate operations. By sending a CR without following it by a LF, you could print over the line you already printed. This allowed effects like accents, bold type, and underlining. Some systems overprinted several times to prevent passwords from being visible in hardcopy. On early serial CRT terminals, CR was one of the ways to control the cursor position in order to update text already on the screen.
But most of the time, you actually just wanted to go to the next line. Rather than requiring the pair of control characters, some systems allowed just one or the other. For example:
U+0085 NEXT LINE
, but the actual EBCDIC value is 0x15
.Why did different systems choose different methods? Simply because there was no universal standard. Where your keyboard probably says "Enter", older keyboards used to say "Return", which was short for Carriage Return. In fact, on a serial terminal, pressing Return actually sends the CR character. If you were writing a text editor, it would be tempting to just use that character as it came in from the terminal. Perhaps that's why the older Macs used just CR.
Now that we have standards, there are more ways to represent line breaks. Although extremely rare in the wild, Unicode has new characters like:
U+2028 LINE SEPARATOR
U+2029 PARAGRAPH SEPARATOR
Even before Unicode came along, programmers wanted simple ways to represent some of the most useful control codes without worrying about the underlying character set. C has several escape sequences for representing control codes:
\a
(for alert) which rings the teletype bell or makes the terminal beep\f
(for form feed) which moves to the beginning of the next page\t
(for tab) which moves the print head to the next horizontal tab position(This list is intentionally incomplete.)
This mapping happens at compile-time--the compiler sees \a
and puts whatever magic value is used to ring the bell.
Notice that most of these mnemonics have direct correlations to ASCII control codes. For example, \a
would map to 0x07 BEL
. A compiler could be written for a system that used something other than ASCII for the host character set (e.g., EBCDIC). Most of the control codes that had specific mnemonics could be mapped to control codes in other character sets.
Huzzah! Portability!
Well, almost. In C, I could write printf("\aHello, World!");
which rings the bell (or beeps) and outputs a message. But if I wanted to then print something on the next line, I'd still need to know what the host platform requires to move to the next line of output. CR LF? CR? LF? NL? Something else? So much for portability.
C has two modes for I/O: binary and text. In binary mode, whatever data is sent gets transmitted as-is. But in text mode, there's a run-time translation that converts a special character to whatever the host platform needs for a new line (and vice versa).
Great, so what's the special character?
Well, that's implementation dependent, too, but there's an implementation-independent way to specify it: \n
. It's typically called the "newline character".
This is a subtle but important point: \n
is mapped at compile time to an implementation-defined character value which (in text mode) is then mapped again at run time to the actual character (or sequence of characters) required by the underlying platform to move to the next line.
\n
is different than all the other backslash literals because there are two mappings involved. This two-step mapping makes \n
significantly different than even \r
, which is simply a compile-time mapping to CR (or the most similar control code in whatever the underlying character set is).
This trips up many C and C++ programmers. If you were to poll 100 of them, at least 99 will tell you that \n
means line feed. This is not entirely true. Most (perhaps all) C and C++ implementations use LF as the magic intermediate value for \n
, but that's an implementation detail. It's feasible for a compiler to use a different value. In fact, if the host character set is not a superset of ASCII (e.g., if it's EBCDIC), then \n
will almost certainly not be LF.
So, in C and C++:
\r
is literally a carriage return.\n
is a magic value that gets translated (in text mode) at run-time to/from the host platform's newline semantics.\r\n
is almost always a portability bug. In text mode, this gets translated to CR followed by the platform's newline sequence--probably not what's intended. In binary mode, this gets translated to CR followed by some magic value that might not be LF--possibly not what's intended.\x0A
is the most portable way to indicate an ASCII LF, but you only want to do that in binary mode. Most text-mode implementations will treat that like \n
.One of other differences is kmalloc will return logical address (else you specify GPF_HIGHMEM). Logical addresses are placed in "low memory" (in the first gigabyte of physical memory) and are mapped directly to physical addresses (use __pa macro to convert it). This property implies kmalloced memory is continuous memory.
In other hand, Vmalloc is able to return virtual addresses from "high memory". These addresses cannot be converted in physical addresses in a direct fashion (you have to use virt_to_page function).
There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.
If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.
Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.
Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.
Just put your data into an Object like this:
var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];
Afterwards stringify it via:
var myString = JSON.stringify(myObject);
You don't need jQuery for this. It's pure JS.
If setting a fixed width on the image is not an option, here's an alternative solution.
Having a parent div with display: table & table-layout: fixed. Then setting the image to display: table-cell and max-width to 100%. That way the image will fit to the width of its parent.
Example:
<style>
.wrapper { float: left; clear: left; display: table; table-layout: fixed; }
img.img-responsive { display: table-cell; max-width: 100%; }
</style>
<div class="wrapper col-md-3">
<img class="img-responsive" src="https://www.google.co.uk/images/srpr/logo11w.png"/>
</div>

Thanks, Tim! Big stumper for me. A few other details others may find helpful:
(Apache2 on Ubuntu 12.04)
I have two sites running on the same server and had just updated the SSL cert for one of them. Upon restarting the server, I got that cryptic message and neither site worked (obviously). I too found the redirect for the log files in the config files. I tracked that down and found the issue (in the log file for the site I had just updated).
My config files are located in /etc/apache2/sites-available
vim or cat the file (cat {filename}) and look for the ErrorLog line. That tells you where to look on your server. cat that file and the error message I found was:
[error] Unable to configure RSA server private key
[error] SSL Library Error: 185073780 error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch
[warn] RSA server certificate CommonName (CN) `<snip>.com' does NOT match server name!?
I had copied one of my cert files to the wrong directory. I simply moved it to the correct directory and everything was fine on the next start. (tip: where those file should be is also in the config file ;)
if what you need to do is specific only for 1 or 2 pages i suggest to use set_time_limit so it did not affect the whole application.
set_time_limit(some_values);
but ofcourse these 2 values (post_max_size & upload_max_filesize) are subject to investigate.
you either can set it via ini_set function
ini_set('post_max_size','20M');
ini_set('upload_max_filesize','2M');
or directly in php.ini file like response above by Hannes, or even set it iin .htaccess like below
php_value upload_max_filesize 2M
php_value post_max_size 20M
Set decoding to true
Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.
$WorkingArray = json_decode(json_encode($data),true);
This works by exploiting the % properties of the list rather than the increments.
for num in range(1,100):
if num % 4 == 1 or num % 4 ==2:
n.append(num)
continue
pass
You cannot have spaces around the =
sign.
When you write:
STR = "foo"
bash tries to run a command named STR
with 2 arguments (the strings =
and foo
)
When you write:
STR =foo
bash tries to run a command named STR
with 1 argument (the string =foo
)
When you write:
STR= foo
bash tries to run the command foo
with STR set to the empty string in its environment.
I'm not sure if this helps to clarify or if it is mere obfuscation, but note that:
STR "=" "foo"
,STR "=foo"
,STR="" foo
.The relevant section of the sh language spec, section 2.9.1 states:
A "simple command" is a sequence of optional variable assignments and redirections, in any sequence, optionally followed by words and redirections, terminated by a control operator.
In that context, a word
is the command that bash is going to run. Any string containing =
(in any position other than at the beginning of the string) which is not a redirection and in which the portion of the string before the =
is a valid variable name is a variable assignment, while any string that is not a redirection or a variable assignment is a command. In STR = "foo"
, STR
is not a variable assignment.
clone() was designed with several mistakes (see this question), so it's best to avoid it.
From Effective Java 2nd Edition, Item 11: Override clone judiciously
Given all of the problems associated with Cloneable, it’s safe to say that other interfaces should not extend it, and that classes designed for inheritance (Item 17) should not implement it. Because of its many shortcomings, some expert programmers simply choose never to override the clone method and never to invoke it except, perhaps, to copy arrays. If you design a class for inheritance, be aware that if you choose not to provide a well-behaved protected clone method, it will be impossible for subclasses to implement Cloneable.
This book also describes the many advantages copy constructors have over Cloneable/clone.
All standard collections have copy constructors. Use them.
List<Double> original = // some list
List<Double> copy = new ArrayList<Double>(original);
Wrap the 'child' function(s) being passed as/with arguments within function wrappers to prevent them being evaluated when the 'parent' function is called.
function outcome(){
return false;
}
function process(callbackSuccess, callbackFailure){
if ( outcome() )
callbackSuccess();
else
callbackFailure();
}
process(function(){alert("OKAY");},function(){alert("OOPS");})
Just go to your AndroidManifest.xml file and add like below
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
then save and run your android project.
Found that using the following worked across most major browsers (Chrome, IE, Safari iOS/OSX) except Firefox (v50.0.2) when using flexbox and relying on width: auto
.
.your_element {
word-wrap: break-word;
overflow-wrap: break-word;
word-break: break-word;
}
Note: you may need to add browser vendor prefixes if you are not using an autoprefixer.
Another thing to watch out for is text using
for spacing can cause line breaks mid-word.
I used this more concisely :
var sys = require('sys')
var exec = require('child_process').exec;
function puts(error, stdout, stderr) { sys.puts(stdout) }
exec("ls -la", puts);
it works perfectly. :)
Since the release of Oracle 12c it is now easier to rearrange columns logically.
Oracle 12c added support for making columns invisible and that feature can be used to rearrange columns logically.
Quote from the documentation on invisible columns:
When you make an invisible column visible, the column is included in the table's column order as the last column.
Create a table:
CREATE TABLE t (
a INT,
b INT,
d INT,
e INT
);
Add a column:
ALTER TABLE t ADD (c INT);
Move the column to the middle:
ALTER TABLE t MODIFY (d INVISIBLE, e INVISIBLE);
ALTER TABLE t MODIFY (d VISIBLE, e VISIBLE);
DESCRIBE t;
Name
----
A
B
C
D
E
I learned about this from an article by Tom Kyte on new features in Oracle 12c.
Try
document.location.host
or
document.location.hostname
The rule of thumb is to use the function most suited to your needs.
If you just want the keys and do not plan to ever read any of the values, use keys():
foreach my $key (keys %hash) { ... }
If you just want the values, use values():
foreach my $val (values %hash) { ... }
If you need the keys and the values, use each():
keys %hash; # reset the internal iterator so a prior each() doesn't affect the loop
while(my($k, $v) = each %hash) { ... }
If you plan to change the keys of the hash in any way except for deleting the current key during the iteration, then you must not use each(). For example, this code to create a new set of uppercase keys with doubled values works fine using keys():
%h = (a => 1, b => 2);
foreach my $k (keys %h)
{
$h{uc $k} = $h{$k} * 2;
}
producing the expected resulting hash:
(a => 1, A => 2, b => 2, B => 4)
But using each() to do the same thing:
%h = (a => 1, b => 2);
keys %h;
while(my($k, $v) = each %h)
{
$h{uc $k} = $h{$k} * 2; # BAD IDEA!
}
produces incorrect results in hard-to-predict ways. For example:
(a => 1, A => 2, b => 2, B => 8)
This, however, is safe:
keys %h;
while(my($k, $v) = each %h)
{
if(...)
{
delete $h{$k}; # This is safe
}
}
All of this is described in the perl documentation:
% perldoc -f keys
% perldoc -f each
Look there is a far easier solution to your problem:
ImageView imageView;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
imageView =(ImageView)findViewById(R.id.your_imageView);
Bitmap imageBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.your_image);
Point screenSize = new Point();
getWindowManager().getDefaultDisplay().getSize(screenSize);
Bitmap temp = Bitmap.createBitmap(screenSize.x, screenSize.x, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(temp);
canvas.drawBitmap(imageBitmap,null, new Rect(0,0,screenSize.x,screenSize.x), null);
imageView.setImageBitmap(temp);
}
It's possible with const qualifier for State:
virtual const ULONG Write(const ULONG &State = 0, bool sequence = true);
If you're working with SQL Developer, you have to put the dbms_view in lowercase. The rest compiled fine for me although I haven't called the procedure from code yet.
CREATE OR REPLACE PROCEDURE "MAT_VIEW_FOO_TBL" AS
BEGIN
dbms_mview.refresh('v_materialized_foo_tbl');
END;
After the merge, it's safe to delete the branch:
git branch -d branch1
Additionally, git will warn you (and refuse to delete the branch) if it thinks you didn't fully merge it yet. If you forcefully delete a branch (with git branch -D
) which is not completely merged yet, you have to do some tricks to get the unmerged commits back though (see below).
There are some reasons to keep a branch around though. For example, if it's a feature branch, you may want to be able to do bugfixes on that feature still inside that branch.
If you also want to delete the branch on a remote host, you can do:
git push origin :branch1
This will forcefully delete the branch on the remote (this will not affect already checked-out repositiories though and won't prevent anyone with push access to re-push/create it).
git reflog
shows the recently checked out revisions. Any branch you've had checked out in the recent repository history will also show up there. Aside from that, git fsck
will be the tool of choice at any case of commit-loss in git.
Since this commit, this is is fixed in the development version of Tomcat. And now in released versions 9.0.13, 8.5.35, and 7.0.92.
From the 9.0.13 changelog:
Ignore an attribute named source on Context elements provided by StandardContext. This is to suppress warnings generated by the Eclipse / Tomcat integration provided by Eclipse. Based on a patch by mdfst13. (markt)
There are similar entries in the 7.0.92 and 8.5.35 changelogs.
The effect of this change is to suppress a warning when a source
attribute is declared on a Context
element in either server.xml or a context.xml. Since those are the two places that Eclipse puts such an attribute, that fixes this particular issue.
TL;DR: update to the latest Tomcat version in its branch, e.g. 9.0.13 or newer.
Use JContainer.Parse(str)
method to check if the str is a valid Json. If this throws exception then it is not a valid Json.
JObject.Parse
- Can be used to check if the string is a valid Json object
JArray.Parse
- Can be used to check if the string is a valid Json Array
JContainer.Parse
- Can be used to check for both Json object & Array
Gotcha!

As others have pointed out one could just delete all the files in the repo and then check them out. I prefer this method and it can be done with the code below
git ls-files -z | xargs -0 rm
git checkout -- .
or one line
git ls-files -z | xargs -0 rm ; git checkout -- .
I use it all the time and haven't found any down sides yet!
For some further explanation, the -z
appends a null character onto the end of each entry output by ls-files
, and the -0
tells xargs
to delimit the output it was receiving by those null characters.
I have a little helper class in all of my applications with methods like:
public static double arrayMax(double[] arr) {
double max = Double.NEGATIVE_INFINITY;
for(double cur: arr)
max = Math.max(max, cur);
return max;
}
The concept is very well explained by the accepted answer, but I find that the more example one sees, the better it sinks in. Here's an incremental example:
1) Boss says "get me number of items we have in stock grouped by brand"
You say: "no problem"
SELECT
BRAND
,COUNT(ITEM_ID)
FROM
ITEMS
GROUP BY
BRAND;
Result:
+--------------+---------------+
| Brand | Count |
+--------------+---------------+
| H&M | 50 |
+--------------+---------------+
| Hugo Boss | 100 |
+--------------+---------------+
| No brand | 22 |
+--------------+---------------+
2) The boss says "Now get me a list of all items, with their brand AND number of items that the respective brand has"
You may try:
SELECT
ITEM_NR
,BRAND
,COUNT(ITEM_ID)
FROM
ITEMS
GROUP BY
BRAND;
But you get:
ORA-00979: not a GROUP BY expression
This is where the OVER (PARTITION BY BRAND)
comes in:
SELECT
ITEM_NR
,BRAND
,COUNT(ITEM_ID) OVER (PARTITION BY BRAND)
FROM
ITEMS;
Whic means:
COUNT(ITEM_ID)
- get the number of itemsOVER
- Over the set of rows(PARTITION BY BRAND)
- that have the same brandAnd the result is:
+--------------+---------------+----------+
| Items | Brand | Count() |
+--------------+---------------+----------+
| Item 1 | Hugo Boss | 100 |
+--------------+---------------+----------+
| Item 2 | Hugo Boss | 100 |
+--------------+---------------+----------+
| Item 3 | No brand | 22 |
+--------------+---------------+----------+
| Item 4 | No brand | 22 |
+--------------+---------------+----------+
| Item 5 | H&M | 50 |
+--------------+---------------+----------+
etc...

it's actually happening because the phone is on offscreen, or you pressed the power button while starting the service. solution for this which worked for me is to start an activity and when it will go in onResume then start the service. in my case, it was booting up and starting a service.
You have added the add marker method call outside the function and that causes it to execute before the initialize method which will be called when google maps script loads and thus the marker is not added because map is not initialized Do as below.... Create separate method TestMarker and call it from initialize.
<script type="text/javascript">
// Standard google maps function
function initialize() {
var myLatlng = new google.maps.LatLng(40.779502, -73.967857);
var myOptions = {
zoom: 12,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
TestMarker();
}
// Function for adding a marker to the page.
function addMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map
});
}
// Testing the addMarker function
function TestMarker() {
CentralPark = new google.maps.LatLng(37.7699298, -122.4469157);
addMarker(CentralPark);
}

An approach which I have been using in my Flask app to serialize Class instance to JSON response.
from json import JSONEncoder
import json
from typing import List
class ResponseEncoder(JSONEncoder):
def default(self, o):
return o.__dict__
class ListResponse:
def __init__(self, data: List):
self.data = data
self.count = len(data)
class A:
def __init__(self, message: str):
self.message = message
class B:
def __init__(self, record: A):
self.record = record
class C:
def __init__(self, data: B):
self.data = data
Now create an instance of A, B, C then encode.
data_a = A('Test Data')
data_b = B(data_a)
data_c = C(data_b)
response = ResponseEncoder().encode(data_c)
json_response = json.loads(response)
Output
{
"data": {
"record": {
"message": "Test Data"
}
}
}
For list type response
records = ['One', 'Two', 'Three']
list_response = ListResponse(records)
response = ResponseEncoder().encode(list_response)
json_response = json.loads(response)
Output
{
"data": [
"One",
"Two",
"Three"
],
"count": 3
}

Responded to a similar question with a potentially simple solution to this if anyone is still after an answer, the catch is it involves the use of redux-sagas:

Or just skip straight to the article I wrote on the topic:
You could also use Format$(Now(), "Short Date") or whatever date format you want. Be aware, this function will return the Date as a string, so using Date() is a better approach.
It is a class that extends another class.

This means the network is slow, and Chrome is replacing a web font (loaded with a @font-face
rule) with a local fallback.
By default, the text rendered with a web font is invisible until the font is downloaded (“flash of invisible text”). With this change, the user on a slow network could start reading right when the content is loaded instead of looking into the empty page for several seconds.
You just have to change the structure of the if...else..endif
somewhat:
if exists(select * from Table where FieldValue='') then begin
select TableID from Table where FieldValue=''
end else begin
insert into Table (FieldValue) values ('')
select TableID from Table where TableID = scope_identity()
end
You could also do:
if not exists(select * from Table where FieldValue='') then begin
insert into Table (FieldValue) values ('')
end
select TableID from Table where FieldValue=''
Or:
if exists(select * from Table where FieldValue='') then begin
select TableID from Table where FieldValue=''
end else begin
insert into Table (FieldValue) values ('')
select scope_identity() as TableID
end
This is one way to accomplish this using PowerShell:

Restores (applies) a previously saved stash based on full or partial stash name.
.DESCRIPTION
Restores (applies) a previously saved stash based on full or partial stash name and then optionally drops the stash. Can be used regardless of whether "git stash save" was done or just "git stash". If no stash matches a message is given. If multiple stashes match a message is given along with matching stash info.
.PARAMETER message
A full or partial stash message name (see right side output of "git stash list"). Can also be "@stash{N}" where N is 0 based stash index.
.PARAMETER drop
If -drop is specified, the matching stash is dropped after being applied.
.EXAMPLE
Restore-Stash "Readme change"
Apply-Stash MyStashName
Apply-Stash MyStashName -drop
Apply-Stash "stash@{0}"
#>
function Restore-Stash {
[CmdletBinding()]
[Alias("Apply-Stash")]
PARAM (
[Parameter(Mandatory=$true)] $message,
[switch]$drop
)
$stashId = $null
if ($message -match "stash@{") {
$stashId = $message
}
if (!$stashId) {
$matches = git stash list | Where-Object { $_ -match $message }
if (!$matches) {
Write-Warning "No stashes found with message matching '$message' - check git stash list"
return
}
if ($matches.Count -gt 1) {
Write-Warning "Found $($matches.Count) matches for '$message'. Refine message or pass 'stash{@N}' to this function or git stash apply"
return $matches
}
$parts = $matches -split ':'
$stashId = $parts[0]
}
git stash apply ''$stashId''
if ($drop) {
git stash drop ''$stashId''
}
}
From Docker docs:
ADD or COPY
Although ADD and COPY are functionally similar, generally speaking, COPY is preferred. That’s because it’s more transparent than ADD. COPY only supports the basic copying of local files into the container, while ADD has some features (like local-only tar extraction and remote URL support) that are not immediately obvious. Consequently, the best use for ADD is local tar file auto-extraction into the image, as in ADD rootfs.tar.xz /.
I faced similar issue while restarting Nginx and found it to be a cause of SeLinux. Be sure to give a try after either disabling SeLinux or temporarily setting it to Permissive mode using below command:
setenforce 0
I hope it helps :)
The problem with your code is that you are selecting the .remode_hover
that is a descendant of .remode_selected
. So the first part of getting your code to work correctly is by removing that space
.reMode_selected.reMode_hover:hover
Then, in order to get the style to not work, you have to override the style set by the :hover
. In other words, you need to counter the background-color
property. So the final code will be
.reMode_selected.reMode_hover:hover {
background-color:inherit;
}
.reMode_hover:hover {
background-color: #f0ac00;
}
An alternative method would be to use :not()
, as stated by others. This will return any element that doesn't have the class or property stated inside the parenthesis. In this case, you would put .remode_selected
in there. This will target all elements that don't have a class of .remode_selected
However, I would not recommend this method, because of the fact that it was introduced in CSS3, so browser support is not ideal.
A third method would be to use jQuery. You can target the .not()
selector, which would be similar to using :not()
in CSS, but with much better browser support

The command for a clean shutdown is http://your-jenkins/safe-shutdown
You may also want to use http://your-jenkins/safe-restart
When compiling with -std=c++11
, one can simply
const char *s = u8"\u0444";
cout << s << endl;
Another way is with Arrays.setAll
, or Arrays.fill
:
String[] v = new String[1000];
Arrays.setAll(v, i -> Integer.toString(i * 30));
//v => ["0", "30", "60", "90"... ]
Arrays.fill(v, "initial value");
//v => ["initial value", "initial value"... ]
This is more usefull for initializing (possibly large) arrays where you can compute each element from its index.
No there is no built-in support for this.
You have to make your own "INIFileReader". Maybe something like this?
var data = new Dictionary<string, string>();
foreach (var row in File.ReadAllLines(PATH_TO_FILE))
data.Add(row.Split('=')[0], string.Join("=",row.Split('=').Skip(1).ToArray()));
Console.WriteLine(data["ServerName"]);
Edit: Updated to reflect Paul's comment.
IDisposable
exists to provide a means for you to clean up unmanaged resources that won't be cleaned up automatically by the Garbage Collector.
All of the resources that you are "cleaning up" are managed resources, and as such your Dispose
method is accomplishing nothing. Your class shouldn't implement IDisposable
at all. The Garbage Collector will take care of all of those fields just fine on its own.
As the previous answer implies, it is not easy to change the color of the ratingbar. The stars are not programmatically drawn, they are images with fixed size and specific color gradients. To change the color you have to create your own star images with different colors then proceed to create your own drawable XML resource and pass it to the ratingsBar class using setProgressDrawable(Drawable d) or XML attribute android:progressDrawable.
Currently you are clearing the name array, you need to call the array then the index you want to unset within the array:
$ar[0]==2
$ar[1]==7
$ar[2]==9
unset ($ar[2])
Two ways of unsetting values within an array:
<?php
# remove by key:
function array_remove_key ()
{
$args = func_get_args();
return array_diff_key($args[0],array_flip(array_slice($args,1)));
}
# remove by value:
function array_remove_value ()
{
$args = func_get_args();
return array_diff($args[0],array_slice($args,1));
}
$fruit_inventory = array(
'apples' => 52,
'bananas' => 78,
'peaches' => 'out of season',
'pears' => 'out of season',
'oranges' => 'no longer sold',
'carrots' => 15,
'beets' => 15,
);
echo "<pre>Original Array:\n",
print_r($fruit_inventory,TRUE),
'</pre>';
# For example, beets and carrots are not fruits...
$fruit_inventory = array_remove_key($fruit_inventory,
"beets",
"carrots");
echo "<pre>Array after key removal:\n",
print_r($fruit_inventory,TRUE),
'</pre>';
# Let's also remove 'out of season' and 'no longer sold' fruit...
$fruit_inventory = array_remove_value($fruit_inventory,
"out of season",
"no longer sold");
echo "<pre>Array after value removal:\n",
print_r($fruit_inventory,TRUE),
'</pre>';
?>
So, unset has no effect to internal array counter!!!
It looks like you can also use a netmask, e.g.
GRANT ... TO 'user'@'192.168.0.0/255.255.255.0' IDENTIFIED BY ...
Best way is to make function for this
FUNCTION:
$.fn.escape = function (callback) {
return this.each(function () {
$(document).on("keydown", this, function (e) {
var keycode = ((typeof e.keyCode !='undefined' && e.keyCode) ? e.keyCode : e.which);
if (keycode === 27) {
callback.call(this, e);
};
});
});
};
EXAMPLE:
$("#my-div").escape(function () {
alert('Escape!');
})
I made a reactive version that accepts callbacks for stdOut and StdErr.
onStdOut
and onStdErr
are called asynchronously,
as soon as data arrives (before the process exits).
public static Int32 RunProcess(String path,
String args,
Action<String> onStdOut = null,
Action<String> onStdErr = null)
{
var readStdOut = onStdOut != null;
var readStdErr = onStdErr != null;
var process = new Process
{
StartInfo =
{
FileName = path,
Arguments = args,
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardOutput = readStdOut,
RedirectStandardError = readStdErr,
}
};
process.Start();
if (readStdOut) Task.Run(() => ReadStream(process.StandardOutput, onStdOut));
if (readStdErr) Task.Run(() => ReadStream(process.StandardError, onStdErr));
process.WaitForExit();
return process.ExitCode;
}
private static void ReadStream(TextReader textReader, Action<String> callback)
{
while (true)
{
var line = textReader.ReadLine();
if (line == null)
break;
callback(line);
}
}
The following will run executable
with args
and print
to the console.
RunProcess(
executable,
args,
s => { Console.ForegroundColor = ConsoleColor.White; Console.WriteLine(s); },
s => { Console.ForegroundColor = ConsoleColor.Red; Console.WriteLine(s); }
);
In neural networks, it is good idea not just to normalize data but also to scale them. This is intended for faster approaching to global minima at error surface. See the following pictures:
Pictures are taken from the coursera course about neural networks. Author of the course is Geoffrey Hinton.
in my case the problem was into outdated "../bootstrap/cache/packages.php and services.php"
I have had to. drop those files and rerun composer install...

The array you created by Dim s(0) As String
IS NOT EMPTY
In VB.Net, the subscript you use in the array is index of the last element. VB.Net by default starts indexing at 0, so you have an array that already has one element.
You should instead try using System.Collections.Specialized.StringCollection
or (even better) System.Collections.Generic.List(Of String)
. They amount to pretty much the same thing as an array of string, except they're loads better for adding and removing items. And let's be honest: you'll rarely create an empty string array without wanting to add at least one element to it.
If you really want an empty string array, declare it like this:
Dim s As String()
or
Dim t() As String
There is no way you can hidde the keyboard properly with js because its a OS problem, so one thing you can easy do to "hidde" the keyboard, is instead of using an input Element you can make any "non-input html element" a key listener element just by adding the [tabindex] attribute, and then you can easily listen the keydown and keyup events and store the "$event.target.value" in a variable to get the input.
The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.
The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.
Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.
The aggregation framework was introduced in mongodb 2.2 . You can use the string operator "$strcasecmp" to make a case-insensitive comparison between strings. It's more recommended and easier than using regex.
Here's the official document on the aggregation command operator: https://docs.mongodb.com/manual/reference/operator/aggregation/strcasecmp/#exp._S_strcasecmp .
I was just creating the database link incorrectly.
Simple fix for me was to simply change 'SID' to SERVICE_NAME
CREATE DATABASE LINK my_db_link
CONNECT TO myUser IDENTIFIED BY myPassword
USING
'
(
DESCRIPTION=
(
ADDRESS=
(PROTOCOL=TCP)
(HOST=host-name-heren)
(PORT=1521)
)
(CONNECT_DATA=(SID=theNameOfTheDatabase))
)';
Changing
SID=theNameOfTheDatabase
to
SERVICE_NAME=theNameOfTheDatabase
resolved my issue.
You can simply get the reference of your buttons using jQuery, and prevent its propagation like below:
$(document).ready(function () {
$('#BUTTON_ID').click(function(e) {
e.preventDefault();
e.stopPropagation();
e.stopImmediatePropagation();
return false;
});});
Try this:
<!DOCTYPE html>
<html>
<body>
<p>Add Section</p>
<label>First Number:</label>
<input id="txt1" type="text"/><br />
<label>Second Number:</label>
<input id="txt2" type="text"/><br />
<input type="button" name="Add" value="Add" onclick="addTwoNumber()"/>
<p id="demo"></p>
<script>
function myFunction() {
document.getElementById("demo").innerHTML = Date();
}
function addTwoNumber(){
var a = document.getElementById("txt1").value;
var b = document.getElementById("txt2").value;
var x = Number(a) + Number(b);
document.getElementById("demo").innerHTML = "Add Value: " + x;
}
</script>
</body>
</html>
To convert a const char*
to char*
you could create a function like this :
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
char* unconstchar(const char* s) {
if(!s)
return NULL;
int i;
char* res = NULL;
res = (char*) malloc(strlen(s)+1);
if(!res){
fprintf(stderr, "Memory Allocation Failed! Exiting...\n");
exit(EXIT_FAILURE);
} else{
for (i = 0; s[i] != '\0'; i++) {
res[i] = s[i];
}
res[i] = '\0';
return res;
}
}
int main() {
const char* s = "this is bikash";
char* p = unconstchar(s);
printf("%s",p);
free(p);
}
The only solution I can think of is to install VMWare or any other VT then install OSX on a VM.
It works pretty good for testing.
//In module.js add below code
export function multiply() {

All too often a new developer asks this simple question which is a common problem specifically with Visual Studio IDE's. Few people answer the specific question and often critique the question or give "guesses" for solutions which don't answer the common problems. The first common problem is the IDE leads you to create new projects rather than add new files (.java, .py, .cpp, .c) to the existing solution (by default it creates a new solution) unless you change the project name and add to the current solution. This problem occurs for Python, java, c#, C++ and C project folders.
The new developer selecting "new>project>project name and changing the solution directory to "use same solution" still creates a new "project" in the same solution space, but not in the same directory space as the current user interface file or command line file which still leads to problems with "package not found" errors when building and running the project or solution. This is why the above coding suggestions to importing packages, classes, methods and functions only work (and thus don't answer the question) when the "library" file or "separate behavior" file is not only in the same solution directory path, but also in the same "user interface" or "command shell" application directory space. This does does not happen when you add another project using the new>project>project type commands of the IDE. The problem here is the new project is stored in a different directory than the existing Client or User interface code files. To create a new "file" in the same project space rather than new project the beginner needs to do the following that Microsoft won't do for you and even misleads you away from the intuitively obvious by default.
NOW the code recommendations to import libraries or using namespaces will work as described in the comments above and you don't have to change path statements or change solutions paths and solution names that Microsoft won't let you change easily (i.e. you can change the filenames or project names but the IDE won't automatically change the project path or the solution path names).
The following is a Python example but works similar for C#, java, or C/C++ using the includes, namespaces or using code commands appropriate to each language to find code in other classes/projects in the SAME DIRECTORY SPACE.
The application file "hello world" importing from other code files in the same directory.
Note the python white space delimiters are not going to space correctly in this stackoverflow comment editor:
print ("test")
from CIXMPythonFacade import ClassA
c1=ClassA
c1.methodA()
from CIXMPythonFacade import functionA
functionA()
class ClassName(object):
def __init__(object, parameter):
object.parameter = value
The library file or "façade" file containing classes, methods or functions you want to import.
class class1(object):
"""description of class"""
class ClassA(object):
print ("test2")
def methodA():
print ("test3")
def functionA ():
print ("test4")
return (0)
pass
NOW how do you actually solve the mess that the IDE leads you into? To import code from another file in the same directory space you add a reference to it.
OK so now that you have this problem solved, how do you really link two separate projects together in the same solution space?
Microsoft really, really needs to fix these problem so you can intuitively create what most people want to create as new files in the same directories and remove solutions by selecting them and deleting them from the IDE. Beginners get so frustrated with directory path statements so flexible for seasoned developers, but so unfair to new developers in their defaults.
Hope this really helps you new guys and stops seasoned developers from giving you the wrong answers that don't work for you. They assume you already understand path statements and just want to type the right code...which is also why the tunnel in on trying to correct your code but does not help you fix the problem. This is probably the most common problem continually described on stackoverflow with wrong answers that don't work for new programmers.
HTML:
<div class="container">
<span>
<img ... >
</span>
<span>
<img ... >
</span>
<span>
<img ... >
</span>
</div>
CSS:
.container{ width:50%; margin:0 auto; text-align:center}
.container span{ width:30%; margin:0 1%; }
I haven't tested this, but hope this will work.
You can add 'display:inline-block' to .container span to make the span to have fixed 30% width
Using individual regular expressions to test the different parts would be considerably easier than trying to get one single regular expression to cover all of them. It also makes it easier to add or remove validation criteria.
Note, also, that your usage of .filter()
was incorrect; it will always return a jQuery object (which is considered truthy in JavaScript). Personally, I'd use an .each()
loop to iterate over all of the inputs, and report individual pass/fail statuses. Something like the below:
$(".buttonClick").click(function () {
$("input[type=text]").each(function () {
var validated = true;
if(this.value.length < 8)
validated = false;
if(!/\d/.test(this.value))
validated = false;
if(!/[a-z]/.test(this.value))
validated = false;
if(!/[A-Z]/.test(this.value))
validated = false;
if(/[^0-9a-zA-Z]/.test(this.value))
validated = false;
$('div').text(validated ? "pass" : "fail");
// use DOM traversal to select the correct div for this input above
});
});
The solution in a more elegant way.
var myData=['237','124','255','124','366','255'];
console.log(Array.from(new Set(myData)).sort());

# * $ROLE_LOCAL will be the user that access the db for maintenance and
# administration. $ROLE_REMOTE will be the user that access the db from the webapp
# * you have to change '$ROLE_LOCAL', '$ROLE_REMOTE' and '$DB'
# strings with your desired names

To make use of regular expressions directly in Excel formulas the following UDF (user defined function) can be of help. It more or less directly exposes regular expression functionality as an excel function.
It takes 2-3 parameters.
$0
, $1
, $2
, and so on. $0
is the entire match, $1
and up correspond to the respective match groups in the regular expression. Defaults to $0
.Extracting an email address:
=regex("Peter Gordon: [email protected], 47", "\w+@\w+\.\w+")
=regex("Peter Gordon: [email protected], 47", "\w+@\w+\.\w+", "$0")
Results in: [email protected]
Extracting several substrings:
=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "E-Mail: $2, Name: $1")
Results in: E-Mail: [email protected], Name: Peter Gordon
To take apart a combined string in a single cell into its components in multiple cells:

=regex("Peter Gordon: [email protected], 47", "^(.+): (.+), (\d+)$", "$" & 2)
Results in: Peter Gordon
[email protected]
...

^[+-]?(([1-9][0-9]*)?[0-9](\.[0-9]*)?|\.[0-9]+)$
should reflect what people usually think of as a well formed decimal number.
The digits before the decimal point can be either a single digit, in which case it can be from 0 to 9, or more than one digits, in which case it cannot start with a 0.
If there are any digits present before the decimal sign, then the decimal and the digits following it are optional. Otherwise, a decimal has to be present followed by at least one digit. Note that multiple trailing 0's are allowed after the decimal point.
grep -E '^[+-]?(([1-9][0-9]*)?[0-9](\.[0-9]*)?|\.[0-9]+)$'

I have come across other similar question here. Both of above answers are perfect, but here trying to add additional information for someone looking for SOAP1.1, and not SOAP1.2.
Just change one line code provided by @acdcjunior, use SOAPMessageFactory1_1Impl
implementation, it will change namespace to xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/", which is SOAP1.1 implementation.
Change callSoapWebService
method first line to following.

I hope it will be helpful to others.
Inflater actually some sort of convert to data, views, instances, to visible UI representation.. ..thus it make use of data feed into from maybe adapters, etc. programmatically. then integrating it with an xml you defined, that tells it how the data should be represented in UI
user: USER
this.user = ({} as USER)
As you said - there is one stand alone answer to this issue.
I had same issue after changing theme. Memory was set to 1024 before, so that's not the problem. Cache was cleared and there was nothing useful in error log.
In my case solution was different - old theme had custom homepage template... Switching it to standard one fixed it.
The source code for the Android mobile application open-gpstracker which you appreciated is available here.
You can checkout the code using SVN client application or via Git:
Debugging the source code will surely help you.
before going for the step "compile -DIPLIB=NONE filename.cxx" take the path of VIsual Studio installation upto the vcvarsall batch file and change the configuration as shown below.
*C:\apps\MVS9\VC\vcvarsall.bat x86_amd64*
now next step should be
compile -64bit -DIPLIB=none filename.cxx
this solved the problem for me
What you are looking for is the POSIX blank
character class. In Perl it is referenced as:
[[:blank:]]
in Java (don't forget to enable UNICODE_CHARACTER_CLASS
):
\p{Blank}
Compared to the similar \h
, POSIX blank
is supported by a few more regex engines (reference). A major benefit is that its definition is fixed in Annex C: Compatibility Properties of Unicode Regular Expressions and standard across all regex flavors that support Unicode. (In Perl, for example, \h
chooses to additionally include the MONGOLIAN VOWEL SEPARATOR
.) However, an argument in favor of \h
is that it always detects Unicode characters (even if the engines don't agree on which), while POSIX character classes are often by default ASCII-only (as in Java).
But the problem is that even sticking to Unicode doesn't solve the issue 100%. Consider the following characters which are not considered whitespace in Unicode:
U+180E MONGOLIAN VOWEL SEPARATOR
U+200B ZERO WIDTH SPACE
U+200C ZERO WIDTH NON-JOINER
U+200D ZERO WIDTH JOINER
U+2060 WORD JOINER
U+FEFF ZERO WIDTH NON-BREAKING SPACE
Taken from https://en.wikipedia.org/wiki/White-space_character
The aforementioned Mongolian vowel separator isn't included for what is probably a good reason. It, along with 200C and 200D, occur within words (AFAIK), and therefore breaks the cardinal rule that all other whitespace obeys: you can tokenize with it. They're more like modifiers. However, ZERO WIDTH SPACE
, WORD JOINER
, and ZERO WIDTH NON-BREAKING SPACE
(if it used as other than a byte-order mark) fit the whitespace rule in my book. Therefore, I include them in my horizontal whitespace character class.
In Java:
static public final String HORIZONTAL_WHITESPACE = "[\\p{Blank}\\u200B\\u2060\\uFFEF]"
In C++ you are supposed to declare functions before you can use them. In your code integrate
is not declared before the point of the first call to integrate
. The same applies to sum
. Hence the error. Either reorder your definitions so that function definition precedes the first call to that function, or introduce a [forward] non-defining declaration for each function.
Additionally, defining external non-inline functions in header files in a no-no in C++. Your definitions of SkewNormalEvalutatable::SkewNormalEvalutatable
, getSkewNormal
, integrate
etc. have no business being in header file.
Also SkewNormalEvalutatable e();
declaration in C++ declares a function e
, not an object e
as you seem to assume. The simple SkewNormalEvalutatable e;
will declare an object initialized by default constructor.
Also, you receive the last parameter of integrate
(and of sum
) by value as an object of Evaluatable
type. That means that attempting to pass SkewNormalEvalutatable
as last argument of integrate
will result in SkewNormalEvalutatable
getting sliced to Evaluatable
. Polymorphism won't work because of that. If you want polymorphic behavior, you have to receive this parameter by reference or by pointer, but not by value.
string::c.str()
returns a string of type const char *
as seen here
A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str())
;
While the above may work, it is undefined behaviour, and unsafe.
Here's a nicer solution using templates:
char * my_argument = const_cast<char*> ( ...c_str() );
I am using this base class connection with mysql:
"base.js"
var mysql = require("mysql");
var pool = mysql.createPool({
connectionLimit : 10,
host: Config.appSettings().database.host,
user: Config.appSettings().database.username,
password: Config.appSettings().database.password,
database: Config.appSettings().database.database
});
var DB = (function () {
function _query(query, params, callback) {
pool.getConnection(function (err, connection) {
if (err) {
connection.release();
callback(null, err);
throw err;
}
connection.query(query, params, function (err, rows) {
connection.release();
if (!err) {
callback(rows);
}
else {
callback(null, err);
}
});
connection.on('error', function (err) {
connection.release();
callback(null, err);
throw err;
});
});
};
return {
query: _query
};
})();
module.exports = DB;
Just use it like that:
var DB = require('../dal/base.js');
DB.query("select * from tasks", null, function (data, error) {
callback(data, error);
});
Your "bad" output is UTF-8 displayed as CP1252.
On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:
df.to_csv('file.csv',encoding='utf-8-sig')
That encoder will add the BOM.
Two very different types of Pipes Angular - Pipes and RxJS - Pipes
A pipe takes in data as input and transforms it to a desired output. In this page, you'll use pipes to transform a component's birthday property into a human-friendly date.
import { Component } from '@angular/core';
@Component({
selector: 'app-hero-birthday',
template: `<p>The hero's birthday is {{ birthday | date }}</p>`
})
export class HeroBirthdayComponent {
birthday = new Date(1988, 3, 15); // April 15, 1988
}
Observable operators are composed using a pipe method known as Pipeable Operators. Here is an example.
import {Observable, range} from 'rxjs';
import {map, filter} from 'rxjs/operators';
const source$: Observable<number> = range(0, 10);
source$.pipe(
map(x => x * 2),
filter(x => x % 3 === 0)
).subscribe(x => console.log(x));
The output for this in the console would be the following:
0
6
12
18
For any variable holding an observable, we can use the .pipe() method to pass in one or multiple operator functions that can work on and transform each item in the observable collection.
So this example takes each number in the range of 0 to 10, and multiplies it by 2. Then, the filter function to filter the result down to only the odd numbers.
No Java doesn't have any destructors .The main reason behind it in Java is the Garbage Collectors that passively works in the background always and all the objects are made in the heap memory , that is the place where GC works .In c++ there we have to explicitly call the delete function since there is no Garbage collector like thing.
I use the reflections in the toString() implementation of my preference class to see the class members and values (simple and quick debugging).
The simplified code I'm using:
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
Class<?> thisClass = null;
try {
thisClass = Class.forName(this.getClass().getName());
Field[] aClassFields = thisClass.getDeclaredFields();
sb.append(this.getClass().getSimpleName() + " [ ");
for(Field f : aClassFields){
String fName = f.getName();
sb.append("(" + f.getType() + ") " + fName + " = " + f.get(this) + ", ");
}
sb.append("]");
} catch (Exception e) {
e.printStackTrace();
}
return sb.toString();
}
I hope that it will help someone, because I also have searched.
Assuming that I
is your input image and F
is its Fourier Transform (i.e. F = fft2(I)
)
You can use this code:
F = fftshift(F); % Center FFT
F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1
imshow(F,[]); % Display the result
Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.
The answer from Andrei means that you can use HttpContext
just as you would use System.Web.HttpContext.Current
. For example, if you want to do this:
System.Web.HttpContext.Current.User.Identity.Name
you should instead do this:
HttpContext.User.Identity.Name
Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.
Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.
In view.py Implement function like,

return response
A year later, stumbled across this question for a inline LI
problem, but have found a great solution that may apply here.
http://robertnyman.com/2010/02/24/css-display-inline-block-why-it-rocks-and-why-it-sucks/

Basic qustion if you are using generics in your base control. If yes:
lets say we have control:
public class MyComboDropDown : ComboDropDownComon<MyType>
{
public MyComboDropDown() { }
}
MyComboDropDown will not allow to open designer on it and will be not shown in Toolbox. Why? Because base control is not already compiled - when MyComboDropDown is complied. You can modify to this:
public class MyComboDropDown : MyComboDropDownBase
{
public MyComboDropDown() { }
}
public class MyComboDropDownBase : ComboDropDownComon<MyType>
{
}
Than after rebuild, and reset toolbox it should be able to see MyComboDropDown in designer and also in Toolbox
Looking over the provided solutions I'm always think about drawbacks of modern education in IT field. Most of the developers are forgetting that even modern CPU's suffer from executing conditional operators, while arithmetics operations, especially with powers of 2 are faster. So on the purpose I'm showing this solution in PHP thread without any optimizations:
list($year,$month,$day) = explode("-",$birthday);
$age=floor(((date("Y")-$year)*512+(date("m")-$month)*32+date("d")-$day)/512);
In other languages which have strict type definitions and capable replacing * and / by shifts, this formula will "fly". Also changing divisor you can calculate age in months, weeks &etc. Be carefull, the order of operands in differences is essential
you can try with this way
android:background="@color/white"
Yes, a static class
for storing constants would be just fine, except for constants that are related to specific types.
Using
<BR>
is not allways enough. MS Outlook 2007 will ignore this if you dont tell outlook that it is a selfclosing html tag by using
<BR />
What you want is a SQL case statement. The form of these is either:
select case [expression or column]
when [value] then [result]
when [value2] then [result2]
else [value3] end
or:
select case
when [expression or column] = [value] then [result]
when [expression or column] = [value2] then [result2]
else [value3] end
In your example you are after:
declare @temp as varchar(100)
set @temp='Measure'
select case @temp
when 'Measure' then Measure
else OtherMeasure end
from Measuretable
Try the ggplot2 function, cut_number
:
library(ggplot2)
x <- 1:10
n <- 3
cut_number(x, n) # labels = FALSE if you just want an integer result
#> [1] [1,4] [1,4] [1,4] [1,4] (4,7] (4,7] (4,7] (7,10] (7,10] (7,10]
#> Levels: [1,4] (4,7] (7,10]
# if you want it split into a list:
split(x, cut_number(x, n))
#> $`[1,4]`
#> [1] 1 2 3 4
#>
#> $`(4,7]`
#> [1] 5 6 7
#>
#> $`(7,10]`
#> [1] 8 9 10
I find this lecture very valuable https://vimeo.com/190275665, in point 3 it summarizes these generators and also gives some performance analysis and guideline one when you use each one.
The Replace
operator means Replace something with something else; do not be confused with removal functionality.
Also you should send the result processed by the operator to a variable or to another operator. Neither .Replace()
, nor -replace
modifies the original variable.
To remove all spaces, use 'Replace any space symbol with empty string'
$string = $string -replace '\s',''
To remove all spaces at the beginning and end of the line, and replace all double-and-more-spaces or tab symbols to spacebar symbol, use
$string = $string -replace '(^\s+|\s+$)','' -replace '\s+',' '
or the more native System.String
method
$string = $string.Trim()
Regexp is preferred, because ' '
means only 'spacebar' symbol, and '\s'
means 'spacebar, tab and other space symbols'. Note that $string.Replace()
does 'Normal' replace, and $string -replace
does RegEx replace, which is more heavy but more functional.
Note that RegEx have some special symbols like dot (.
), braces ([]()
), slashes (\
), hats (^
), mathematical signs (+-
) or dollar signs ($
) that need do be escaped. ( 'my.space.com' -replace '\.','-'
=> 'my-space-com'
. A dollar sign with a number (ex $1
) must be used on a right part with care
'2033' -replace '(\d+)',$( 'Data: $1')
Data: 2033
UPDATE: You can also use $str = $str.Trim()
, along with TrimEnd()
and TrimStart()
. Read more at System.String MSDN page.
I've run a benchmark today and came up with interesting result. Among these three:
var count1 = typeof(TestEnum).GetFields().Length;
var count2 = Enum.GetNames(typeof(TestEnum)).Length;
var count3 = Enum.GetValues(typeof(TestEnum)).Length;
GetNames(enum) is by far the fastest!
| Method | Mean | Error | StdDev |
|--------------- |---------- |--------- |--------- |
| DeclaredFields | 94.12 ns | 0.878 ns | 0.778 ns |
| GetNames | 47.15 ns | 0.554 ns | 0.491 ns |
| GetValues | 671.30 ns | 5.667 ns | 4.732 ns |

MyDialogFragment f = new MyDialogFragment();
// Supply num input as an argument.
Bundle args = new Bundle();

super.onCreate(savedInstanceState);
mNum = getArguments().getInt("num");
...

uintptr_t
is an unsigned integer type that is capable of storing a data pointer. Which typically means that it's the same size as a pointer.
It is optionally defined in C++11 and later standards.
A common reason to want an integer type that can hold an architecture's pointer type is to perform integer-specific operations on a pointer, or to obscure the type of a pointer by providing it as an integer "handle".

Don't use Integrated Security.
Use User Id=yourUser; pwd=yourPwd;
This solves the problem.
It is possible to define a function from inside another function. the inner function does not exist until the outer function gets executed.
echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';
$x=x(2);
echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';
Output
y is not defined
y is defined
Simple thing you can not call function y before executed x
You can enable SSL on XAMPP by creating self signed certificates and then installing those certificates. Type the below commands to generate and move the certificates to ssl folders.
openssl genrsa -des3 -out server.key 1024
openssl req -new -key server.key -out server.csr
cp server.key server.key.org
openssl rsa -in server.key.org -out server.key
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
cp server.crt /opt/lampp/etc/ssl.crt/domainname.crt
cp server.key /opt/lampp/etc/ssl.key/domainname.key
(Use sudo with each command if you are not the super user)
Now, Check that mod_ssl is enabled in [XAMPP_HOME]/etc/httpd.conf:
LoadModule ssl_module modules/mod_ssl.so
Add a virtual host, in this example "localhost.domainname.com" by editing [XAMPP_HOME]/etc/extra/httpd-ssl.conf as follows:
<virtualhost 127.0.1.4:443>
ServerName localhost.domainname.com
ServerAlias localhost.domainname.com *.localhost.domainname.com
ServerAdmin admin@localhost
DocumentRoot "/opt/lampp/htdocs/"
DirectoryIndex index.php
ErrorLog /opt/lampp/logs/domainname.local.error.log
CustomLog /opt/lampp/logs/domainname.local.access.log combined
SSLEngine on
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLCertificateFile /opt/lampp/etc/ssl.crt/domainname.crt
SSLCertificateKeyFile /opt/lampp/etc/ssl.key/domainname.key
<directory /opt/lampp/htdocs/>
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</directory>
BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
</virtualhost>
Add the following entry to /etc/hosts:
127.0.1.4 localhost.domainname.com
Now, try installing the certificate/ try importing certificate to browser. I have checked this and this worked on Ubuntu.
static void Main(string[] args)
{
//---listen at the specified IP and port no.---
IPAddress localAdd = IPAddress.Parse(SERVER_IP);
TcpListener listener = new TcpListener(localAdd, PORT_NO);
Console.WriteLine("Listening...");
listener.Start();
while (true)
{
//---incoming client connected---
TcpClient client = listener.AcceptTcpClient();
//---get the incoming data through a network stream---
NetworkStream nwStream = client.GetStream();
byte[] buffer = new byte[client.ReceiveBufferSize];
//---read incoming stream---
int bytesRead = nwStream.Read(buffer, 0, client.ReceiveBufferSize);
//---convert the data received into a string---
string dataReceived = Encoding.ASCII.GetString(buffer, 0, bytesRead);
Console.WriteLine("Received : " + dataReceived);
//---write back the text to the client---
Console.WriteLine("Sending back : " + dataReceived);
nwStream.Write(buffer, 0, bytesRead);
client.Close();
}
listener.Stop();
Console.ReadLine();
}
In addition to @Nudier Mena answer, keep a while loop to keep the server in listening mode. So that we can have multiple instance of client connected.
You have declared an array that can store 8 elements not 9.
this.posStatus = new int[8];
It means postStatus will contain 8 elements from index 0 to 7.
To check whether a process/command returned 0 or not, use the operators && == 0 or
: not == 0 ||
Just add operator to your script:
execute_command && (
echo\Return 0, with no execution error
) || (
echo\Return non 0, something went wrong
)
command && echo\Return 0 || echo\Return non 0
I am almost sure you can split values across multiple INs using OR:
select * from table1 where ID in (1,2,3,4,...,1000) or
ID in (1001,1002,...,2000)
This works.

final JButton start = new JButton("Start");
p.add(start);
p.add(stop);
f.getContentPane().add(p);
stop.setEnabled(false);
stop.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
start.setEnabled(true);
stop.setEnabled(false);
}
});
start.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
start.setEnabled(false);
stop.setEnabled(true);
}
});
f.setVisible(true);
}
/**

You can create the PDF document using PdfSharp. It is an open source .NET library.
When trying to print the document it get worse. I have looked allover for a open source way of doing it. There are some ways do do it using AcroRd32.exe but it all depends on the version, and it cannot be done without acrobat reader staying open.
I finally ended up using VintaSoftImaging.NET SDK. It costs some money but is much cheaper than the alternative and it solves the problem really easy.
var doc = new Vintasoft.Imaging.Print.ImagePrintDocument { DocumentName = @"C:\Test.pdf" };
doc.Print();
That just prints to the default printer without showing. There are several alternatives and options.
A way to do this without Linq & Lambdas
string source = "a,b, b, c";
string[] items = source.Split(new char[] { ',', ' ' }, StringSplitOptions.RemoveEmptyEntries);
If need to run ant in eclipse with inbuilt eclipse jdk add the below line in build.xml
<property name="build.compiler" value="org.eclipse.jdt.core.JDTCompilerAdapter"/>
Just to be really clear, this has nothing to do with enumerate
and everything to do with list comprehension syntax.
This list comprehension returns a list of tuples:
[(i,j) for i in range(3) for j in 'abc']
this a list of dicts:
[{i:j} for i in range(3) for j in 'abc']
a list of lists:
[[i,j] for i in range(3) for j in 'abc']
a syntax error:
[i,j for i in range(3) for j in 'abc']
Which is inconsistent (IMHO) and confusing with dictionary comprehensions syntax:
>>> {i:j for i,j in enumerate('abcdef')}
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f'}
And a set of tuples:
>>> {(i,j) for i,j in enumerate('abcdef')}
set([(0, 'a'), (4, 'e'), (1, 'b'), (2, 'c'), (5, 'f'), (3, 'd')])
As Óscar López stated, you can just pass the enumerate tuple directly:
>>> [t for t in enumerate('abcdef') ]
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f')]
while true ; do
...
if [ something ]; then
break

This can occur when Safari is in private mode browsing. While in private browsing, local storage is not available at all.
One solution is to warn the user that the app needs non-private mode to work.
UPDATE: This has been fixed in Safari 11, so the behaviour is now aligned with other browsers.
Very close to what you posted, actually.
To get the assigned value, or default
if it's missing:
FOO="${VARIABLE:-default}" # If variable not set or null, use default.
Or to assign default

at the same time:

Why not using word-wrap: break-word;
? it's made to allow long words to be able to break and wrap onto the next line.

I was wondering how to do this myself; it seems Gmail has since silently implemented this feature. I created the following filter:
Matches: subject:([test])
Do this: Skip Inbox
And then I sent a message with the subject
[test] foo
And the message was archived! So it seems all that is necessary is to create a filter for the subject prefix you wish to handle.
You're really close. Try using a large row number with End(xlUp)
Function ultimaFilaBlanco(col As String) As Long
Dim lastRow As Long
With ActiveSheet
lastRow = ActiveSheet.Cells(1048576, col).End(xlUp).row
End With
ultimaFilaBlanco = lastRow
End Function
You declare parent as Parent, so java will provide only methods and attributes of the Parent class.
Child child = new Child();
should work. Or
Parent child = new Child();
((Child)child).salary = 1;
I once tried to do those round corners and drop shadows with css3. Later on, I found it is still poorly supported (Internet Explorer(s), of course!)
I ended up trying to do that in JS (HTML canvas with IE Canvas), but it impacts the performance a lot (even on my C2D machine). In short, if you really need the effect, consider JS libraries (most of them should be able to run on IE6) but don't over do it due to performance issues; if you still need an alternative... you could use SFiR, then PS it and SFiR it. CSS3 isn't ready today.
Per JamieL's answer to another post:
Since Express.js 3x the response object has a json() method which sets all the headers correctly for you.
Example:
res.json({"foo": "bar"});
You can try to clone using the HTTPS
protocol. Terminal command:
git clone https://github.com/RestKit/RestKit.git
There might be a semicolon or bracket missing a line before your pasted line.
It seems fine to me; every string is allowed as an array index.
app.config
<client>
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="LisansSoap"
contract="Lisans.LisansSoap"
name="LisansSoap" />
</client>
program
Lisans.LisansSoapClient test = new LisansSoapClient("LisansSoap",
"http://webservis.uzmanevi.com/Lisans/Lisans.asmx");
MessageBox.Show(test.LisansKontrol("","",""));
This can be done without regex
which is more efficient:
var questionText = "1 ding ?"
var index = 0;
var num = "";
do
{
num += questionText[index];
} while (questionText[++index] >= "0" && questionText[index] <= "9");
questionText = questionText.substring(num.length);
And as a bonus, it also stores the number, which may be useful to some people.
There are several ways to assign the equal variables.
The easiest one:
grade_1 = grade_2 = grade_3 = average = 0.0
With unpacking:
grade_1, grade_2, grade_3, average = 0.0, 0.0, 0.0, 0.0
With list comprehension and unpacking:
>>> grade_1, grade_2, grade_3, average = [0.0 for _ in range(4)]
>>> print(grade_1, grade_2, grade_3, average)
0.0 0.0 0.0 0.0
Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.
This tutorial is a very good one for pandas slicing. Make sure you check it out. Onto some snippets... To slice a dataframe with a condition, you use this format:
>>> df[condition]
This will return a slice of your dataframe which you can index using iloc
. Here are your examples:
Get first row where A > 3 (returns row 2)
>>> df[df.A > 3].iloc[0]
A 4
B 6
C 3
Name: 2, dtype: int64
If what you actually want is the row number, rather than using iloc
, it would be df[df.A > 3].index[0]
.
Get first row where A > 4 AND B > 3:
>>> df[(df.A > 4) & (df.B > 3)].iloc[0]
A 5
B 4
C 5
Name: 4, dtype: int64
Get first row where A > 3 AND (B > 3 OR C > 2) (returns row 2)
>>> df[(df.A > 3) & ((df.B > 3) | (df.C > 2))].iloc[0]
A 4
B 6
C 3
Name: 2, dtype: int64
Now, with your last case we can write a function that handles the default case of returning the descending-sorted frame:
>>> def series_or_default(X, condition, default_col, ascending=False):
... sliced = X[condition]
... if sliced.shape[0] == 0:
... return X.sort_values(default_col, ascending=ascending).iloc[0]
... return sliced.iloc[0]
>>>
>>> series_or_default(df, df.A > 6, 'A')
A 5
B 4
C 5
Name: 4, dtype: int64
As expected, it returns row 4.
Edit > Advanced > View White Space. The keyboard shortcut is CTRL+R, CTRL+W. The command is called Edit.ViewWhiteSpace
.
It works in all Visual Studio versions at least since Visual Studio 2010, the current one being Visual Studio 2019 (at time of writing). In Visual Studio 2013, you can also use CTRL+E, S or CTRL+E, CTRL+S.
By default, end of line markers are not visualized. This functionality is provided by the End of the Line extension.
And you should use neither if you have plenty of RAM. Redis and MongoDB come to the price of a general purpose tool. This introduce a lot of overhead.
There was the saying that Redis is 10 times faster than Mongo. That might not be that true anymore. MongoDB (if i remember correctly) claimed to beat memcache for storing and caching documents as long as the memory configurations are the same.
Anyhow. Redis good, MongoDB is good. If you care about substructures and need aggregation go for MongoDB. If storing keys and values is your main concern its all about Redis. (or any other key value store).
You can try it this way!!
var str ="Hello World";
var position = 6;//its 1 based
var newStr = str.substring(0,position - 1) + str.substring(postion, str.length);
alert(newStr);
Here is the live example: http://jsbin.com/ogagaq
file__IO = input('\nEnter file name here to analize with path:: ')
with open(file__IO, 'r') as f:
data = f.read()
line = data.splitlines()
words = data.split()
spaces = data.split(" ")
charc = (len(data) - len(spaces))
print('\n Line number ::', len(line), '\n Words number ::', len(words), '\n Spaces ::', len(spaces), '\n Charecters ::', (len(data)-len(spaces)))
I tried this code & it works as expected.
One options will be to show the selected option above (or below) the select list like following:
HTML
<div id="selText"><span> </span></div><br/>
<select size="4" id="mySelect" style="width:65px;color:#f98ad3;">
<option value="1" selected>option 1 The Long Option</option>
<option value="2">option 2</option>
<option value="3">option 3</option>
<option value="4">option 4</option>
<option value="5">option 5 Another Longer than the Long Option ;)</option>
<option value="6">option 6</option>
</select>
JavaScript
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"
type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$("select#mySelect").change(function(){
//$("#selText").html($($(this).children("option:selected")[0]).text());
var txt = $($(this).children("option:selected")[0]).text();
$("<span>" + txt + "<br/></span>").appendTo($("#selText span:last"));
});
});
</script>
PS:- Set height of div#selText otherwise it will keep shifting select list downward.
Since you have written a function named foo
and you know it is in myfile.js
why do you need to get this information dynamically?
That being said you can use arguments.callee.toString()
inside the function (this is a string representation of the entire function) and regex out the value of the function name.
Here is a function that will spit out its own name:
function foo() {
re = /^function\s+([^(]+)/
alert(re.exec(arguments.callee.toString())[1]);
}
Actually, drop rows 0 and 1 only requires (any observations containing matched A and C is kept.):
In [335]:
df['AC']=df.A+df.C
In [336]:
print df.drop_duplicates('C', take_last=True) #this dataset is a special case, in general, one may need to first drop_duplicates by 'c' and then by 'a'.
A B C AC
2 foo 1 B fooB
3 bar 1 A barA
[2 rows x 4 columns]
But I suspect what you really want is this (one observation containing matched A and C is kept.):
In [337]:
print df.drop_duplicates('AC')
A B C AC
0 foo 0 A fooA
2 foo 1 B fooB
3 bar 1 A barA
[3 rows x 4 columns]
Now it is much clearer, therefore:
In [352]:
DG=df.groupby(['A', 'C'])
print pd.concat([DG.get_group(item) for item, value in DG.groups.items() if len(value)==1])
A B C
2 foo 1 B
3 bar 1 A
[2 rows x 3 columns]
Example fetch with authorization header:
fetch('URL_GOES_HERE', {
method: 'post',
headers: new Headers({
'Authorization': 'Basic '+btoa('username:password'),
'Content-Type': 'application/x-www-form-urlencoded'
}),
body: 'A=1&B=2'
});
Even after 9 years of the original post, this helped me.
If you are receiving these types of errors without any clue, there should be a trigger, function related to the table, and obviously it should end up with an SP, or function with selecting/filtering data NOT USING Primary Unique column. If you are searching/filtering using the Primary Unique column there won't be any multiple results. Especially when you are assigning value for a declared variable. The SP never gives you en error but only an runtime error.
"System.Data.SqlClient.SqlException (0x80131904): Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated."
In my case obviously there was no clue, but only this error message. There was a trigger connected to the table and the table updating by the trigger also had another trigger likewise it ended up with two triggers and in the end with an SP. The SP was having a select clause which was resulting in multiple rows.
SET @Variable1 =(
SELECT column_gonna_asign
FROM dbo.your_db
WHERE Non_primary_non_unique_key= @Variable2
If this returns multiple rows, you are in trouble.
The time
function returns the current time (as a time_t
value) in seconds since some point (on Unix systems, since midnight UTC January 1, 1970), and it takes one argument, a time_t
pointer in which the time is stored. Passing NULL
as the argument causes time
to return the time as a normal return value but not store it anywhere else.
Here is a bash function for adding a command to crontab
without duplication
function addtocrontab () {
local frequency=$1
local command=$2
local job="$frequency $command"
cat <(fgrep -i -v "$command" <(crontab -l)) <(echo "$job") | crontab -
}
addtocrontab "0 0 1 * *" "echo hello"
Less than or equal:
User.objects.filter(userprofile__level__lte=0)
Greater than or equal:
User.objects.filter(userprofile__level__gte=0)
Likewise, lt
for less than and gt
for greater than. You can find them all in the documentation.
For csv file formate data will be in below format
"column1", "column2","column3","column4"
And if we will use field terminated by ',' then each column will get values like below.
"column1" "column2" "column3" "column4"
also if any of the column value has comma
as value then it will not work at all .
So the correct way to create a table would be by using OpenCSVSerde
create table tableName (column1 datatype, column2 datatype , column3 datatype , column4 datatype)
ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.OpenCSVSerde'
STORED AS TEXTFILE ;
So many answers, and no one ever made a benchmark to compare sync vs async vs require. I described the difference in use cases of reading json in memory via require, readFileSync and readFile here.
For dynamic arrays (malloc or C++ new) you need to store the size of the array as mentioned by others or perhaps build an array manager structure which handles add, remove, count, etc. Unfortunately C doesn't do this nearly as well as C++ since you basically have to build it for each different array type you are storing which is cumbersome if you have multiple types of arrays that you need to manage.
For static arrays, such as the one in your example, there is a common macro used to get the size, but it is not recommended as it does not check if the parameter is really a static array. The macro is used in real code though, e.g. in the Linux kernel headers although it may be slightly different than the one below:
#if !defined(ARRAY_SIZE)
#define ARRAY_SIZE(x) (sizeof((x)) / sizeof((x)[0]))
#endif
int main()
{
int days[] = {1,2,3,4,5};
int *ptr = days;
printf("%u\n", ARRAY_SIZE(days));
printf("%u\n", sizeof(ptr));
return 0;
}
You can google for reasons to be wary of macros like this. Be careful.
If possible, the C++ stdlib such as vector which is much safer and easier to use.
You can do it with gridview's datarow bound event. try the following sample of code:
protected void grv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[0].Text = "TiTle";
}
}

If you've loaded jQuery, you can see if the height of the content is greater than the viewport height. If not, then you can make it that height (or a little less). I ran the following code in WVGA800 mode in the Android emulator, and then ran it on my Samsung Galaxy Tab, and in both cases it hid the addressbar.
$(document).ready(function() {
if (navigator.userAgent.match(/Android/i)) {
window.scrollTo(0,0); // reset in case prev not scrolled
var nPageH = $(document).height();
var nViewH = window.outerHeight;
if (nViewH > nPageH) {
nViewH -= 250;
$('BODY').css('height',nViewH + 'px');
}
window.scrollTo(0,1);
}
});
That example is pretty vague, but maybe something like this?
items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [''.join(items[3:6])]
It basically does a splice (or assignment to a slice) operation. It removes items 3 to 6 and inserts a new list in their place (in this case a list with one item, which is the concatenation of the three items that were removed.)
For any type of list, you could do this (using the +
operator on all items no matter what their type is):
items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [reduce(lambda x, y: x + y, items[3:6])]
This makes use of the reduce
function with a lambda
function that basically adds the items together using the +
operator.
final Date currentTime = new Date();
final SimpleDateFormat sdf = new SimpleDateFormat("EEE, MMM d, yyyy hh:mm:ss a z");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
System.out.println("UTC time: " + sdf.format(currentTime));
Mathew's answer works for the terminal python shell, but it didn't work for IDLE shell in my case because many versions of python existed before I replaced them all with Python2.7.7. How I solved the problem with IDLE.
cd /Applications/Python\ 2.7/IDLE.app/Contents/Resources/
sudo nano idlemain.py
, enter password if required.os.chdir(os.path.expanduser('~/Documents'))
this line, I added sys.path.append("/Users/admin/Downloads....")
NOTE: replace contents of the quotes with the directory where python module to be addedIf you want to plot a single line connecting all the points in the list
plt.plot(li[:])
plt.show()
This will plot a line connecting all the pairs in the list as points on a Cartesian plane from the starting of the list to the end. I hope that this is what you wanted.
