You can customize the deserialization for any attribute.
Declare your deserialize class using the annotationJsonDeserialize (import com.fasterxml.jackson.databind.annotation.JsonDeserialize
) for the attribute that will be processed. If this is an Enum:
@JsonDeserialize(using = MyEnumDeserialize.class)
private MyEnum myEnum;
This way your class will be used to deserialize the attribute. This is a full example:
public class MyEnumDeserialize extends JsonDeserializer<MyEnum> {
@Override
public MyEnum deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
JsonNode node = jsonParser.getCodec().readTree(jsonParser);
MyEnum type = null;
try{
if(node.get("attr") != null){
type = MyEnum.get(Long.parseLong(node.get("attr").asText()));
if (type != null) {
return type;
}
}
}catch(Exception e){
type = null;
}
return type;
}
}
I'm using Visual Studio 2015 and finally ran across this post.
Yes in order to use
JavaScriptSerializer json = new JavaScriptSerializer();
You must right click on references and under Assemblies --> Framework choose
System.Web.Extensions
Then add in your reference
using System.Web.Script.Serialization;
I found this MSDN forum post which suggests two solutions to your problem.
First solution (not recommended):
Find the .Net Framework 3.5 and 2.0 folder
Copy System.Web.Extensions.dll from 3.5 and System.Web.dll from 2.0 to the application folder
Add the reference to these two assemblies
Change the referenced assemblies property, setting "Copy Local" to true And build to test your application to ensure all code can work
Second solution (Use a different class / library):
The user who had posted the question claimed that Uri.EscapeUriString
and How to: Serialize and Deserialize JSON Data helped him replicate the behavior of JavaScriptSerializer
.
You could also try to use Json.Net. It's a third party library and pretty powerful.
This should help. How can I upload files asynchronously?
As the post suggest I recommend a plugin located here http://malsup.com/jquery/form/#code-samples
A bit late to the party but Juval Lowy addresses this exact scenario in his book and the associated ServiceModelEx library.
Basically he defines ClientBase and ChannelFactory specialisations that allow specifying type-safe header values. I suggesst downloading the source and looking at the HeaderClientBase and HeaderChannelFactory classes.

If you using v1.3.3 then use following property
autoPlay : 5000
Or using latest version then use following property
autoPlay : true
Convert.ToInt32
has 19 overloads or 19 different ways that you can call it. Maybe more in 2010 versions.
It will attempt to convert from the following TYPES;
Object, Boolean, Char, SByte, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Single, Double, Decimal, String, Date
and it also has a number of other methods; one to do with a number base and 2 methods involve a System.IFormatProvider
Parse on the other hand only has 4 overloads or 4 different ways you can call the method.
Integer.Parse( s As String)
Integer.Parse( s As String, style As System.Globalization.NumberStyles )
Integer.Parse( s As String, provider As System.IFormatProvider )
Integer.Parse( s As String, style As System.Globalization.NumberStyles, provider As System.IFormatProvider )
cat file.log | wc -l | grep -oE '\d+'
grep -oE '\d+'

Here is a way how to execute a python script from another python script:
Python 2:
execfile("somefile.py", global_vars, local_vars)
Python 3:
with open("somefile.py") as f:
code = compile(f.read(), "somefile.py", 'exec')
exec(code, global_vars, local_vars)
and you can supply args by providing some other sys.argv
I had this same question a while back and came across one of Scott Hanselman's posts:

i have a data access library which works with both .net core and .net framework.
the trick was in .net core projects to keep the connection strings in a xml file named "app.config" (also for web projects), and mark it as 'copy to output directory',
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="conn1" connectionString="...." providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
ConfigurationManager.ConnectionStrings - will read the connection string.
var conn1 = ConfigurationManager.ConnectionStrings["conn1"].ConnectionString;
A polyfill is a shim which replaces the original call with the call to a shim.
For example, say you want to use the navigator.mediaDevices object, but not all browsers support this. You could imagine a library that provided a shim which you might use like this:
<script src="js/MediaShim.js"></script>
<script>
MediaShim.mediaDevices.getUserMedia(...);
</script>
In this case, you are explicitly calling a shim instead of using the original object or method. The polyfill, on the other hand, replaces the objects and methods on the original objects.
For example:
<script src="js/adapter.js"></script>
<script>
navigator.mediaDevices.getUserMedia(...);
</script>
In your code, it looks as though you are using the standard navigator.mediaDevices object. But really, the polyfill (adapter.js in the example) has replaced this object with its own one.
The one it has replaced it with is a shim. This will detect if the feature is natively supported and use it if it is, or it will work around it using other APIs if it is not.
So a polyfill is a sort of "transparent" shim. And this is what Remy Sharp (who coined the term) meant when saying "if you removed the polyfill script, your code would continue to work, without any changes required in spite of the polyfill being removed".
Here's the code I wrote to find the only visible among a few similar elements, and return the value of its "class" attribute without jQuery:
// Build a NodeList:
var nl = document.querySelectorAll('.myCssSelector');
// convert it to array:
var myArray = [];for(var i = nl.length; i--; myArray.unshift(nl[i]));
// now find the visible (= with offsetWidth more than 0) item:
for (i =0; i < myArray.length; i++){
var curEl = myArray[i];
if (curEl.offsetWidth !== 0){
return curEl.getAttribute("class");
}
}
You can use sys.argv
to get the arguments as a list.
If you need to access individual elements, you can use
sys.argv[i]
where i
is index, 0
will give you the python filename being executed. Any index after that are the arguments passed.
I export lists into YAML format with CPAN YAML package.
l <- list(a="1", b=1, c=list(a="1", b=1))
yaml::write_yaml(l, "list.yaml")
Bonus of YAML that it's a human readable text format so it's easy to read/share/import/etc
$ cat list.yaml
a: '1'
b: 1.0
c:
a: '1'
b: 1.0

When you use the IntelliJ IDE, all the project-specific settings for the project are stored under the .idea
folder.
Project settings are stored with each specific project as a set of xml files under the .idea folder. If you specify the default project settings, these settings will be automatically used for each newly created project.
Check this documentation for the IDE settings and here is their recommendation on Source Control and an example .gitignore file.
Note: If you are using git or some version control system, you might want to set this folder "ignore".
Example - for git, add this directory to .gitignore
. This way, the application is not IDE-specific.
I had c++ codes in my project but i didn't have NDK

If you're only interested in the output from the process, it's easiest to use subprocess' check_output function:
output = subprocess.check_output(["command", "arg1", "arg2"]);
Then output holds the program output to stdout. Check the link above for more info.
$1, $2, etc will contain the value of captures from the last successful match - it's important to check whether the match succeeded before accessing them, i.e.
if ( $var =~ m/( )/ ) { # use $1 etc... }
An example of the problem - $1 contains 'Quick' in both print statements below:
#!/usr/bin/perl
'Quick brown fox' =~ m{ ( quick ) }ix;
print "Found: $1\n";
'Lazy dog' =~ m{ ( quick ) }ix;
print "Found: $1\n";
option -v
is very important. It can exclude a grep
expression itself
e.g.
ps -w | grep sshd | grep -v grep | awk '{print $1}' to get sshd id
try this:
Sub test()
With Application.WorksheetFunction
Cells(.CountA(Columns("A:A")) + 1, 1).Select
End With
End Sub
Hope this works for you.
Deleting registry keys as suggested above got my service stuck in the stopping state. The following procedure worked for me:

Content that is floating does not influence the height of its container. The element contains no content that isn't floating (so nothing stops the height of the container being 0, as if it were empty).
Setting overflow: hidden
on the container will avoid that by establishing a new block formatting context. See methods for containing floats for other techniques and containing floats for an explanation about why CSS was designed this way.
When you use Apache with mod_php apache is enforced in prefork
mode, and not worker
. As, even if php5 is known to support multi-thread, it is also known that some php5 libraries are not behaving very well in multithreaded environments (so you would have a locale call on one thread altering locale on other php threads, for example).
So, if php is not running in cgi way like with php-fpm you have mod_php inside apache and apache in prefork mode. On your tests you have simply commented the prefork settings and increased the worker settings, what you now have is default values for prefork settings and some altered values for the shared ones :
StartServers 20
MinSpareServers 5
MaxSpareServers 10
MaxClients 1024
MaxRequestsPerChild 0
This means you ask apache to start with 20 process, but you tell it that, if there is more than 10 process doing nothing it should reduce this number of children, to stay between 5 and 10 process available. The increase/decrease speed of apache is 1 per minute. So soon you will fall back to the classical situation where you have a fairly low number of free available apache processes (average 2). The average is low because usually you have something like 5 available process, but as soon as the traffic grows they're all used, so there's no process available as apache is very slow in creating new forks. This is certainly increased by the fact your PHP requests seems to be quite long, they do not finish early and the apache forks are not released soon enough to treat another request.
See on the last graphic the small amount of green before the red peak? If you could graph this on a 1 minute basis instead of 5 minutes you would see that this green amount was not big enough to take the incoming traffic without any error message.
Now you set 1024
MaxClients
. I guess the cacti graph are not taken after this configuration modification, because with such modification, when no more process are available, apache would continue to fork new children, with a limit of 1024 busy children. Take something like 20MB of RAM per child (or maybe you have a big memory_limit in PHP and allows something like 64MB or 256MB and theses PHP requests are really using more RAM), maybe a DB server... your server is now slowing down because you have only 768MB of RAM. Maybe when apache is trying to initiate the first 20 children you already reach the available RAM limit.
So. a classical way of handling that is to check the amount of memory used by an apache fork (make some top commands while it is running), then find how many parallel request you can handle with this amount of RAM (that mean parallel apache children in prefork mode). Let's say it's 12, for example. Put this number in apache mpm settings this way:
<IfModule prefork.c>
StartServers 12
MinSpareServers 12
MaxSpareServers 12
MaxClients 12
MaxRequestsPerChild 300
</IfModule>
That means you do not move the number of fork while traffic increase or decrease, because you always want to use all the RAM and be ready for traffic peaks. The 300
means you recyclate each fork after 300 requests, it's better than 0, it means you will not have potential memory leaks issues. MaxClients is set to 12 25 or 50 which is more than 12 to handle the (removed this strange sentende, I can't remember why I said that, if more than 12 requests are incoming the next one will be pushed in the Backlog queue, but you should set MaxClient to your targeted number of processes).ListenBacklog
queue, which can enqueue some requests, you may take a bigger queue, but you would get some timeouts maybe
And yes, that means you cannot handle more than 12 parallel requests.
If you want to handle more requests:
If your problem is really traffic peaks, solutions could be available with caches, like a proxy-cache server. If the problem is a random slowness in PHP then... it's an application problem, do you do some HTTP query to another site from PHP, for example?
And finally, as stated by @Jan Vlcinsky you could try nginx, where php will only be available as php-fpm. If you cannot buy RAM and must handle a big traffic that's definitively desserve a test.
Update: About internal dummy connections (if it's your problem, but maybe not).
Check this link and this previous answer. This is 'normal', but if you do not have a simple virtualhost theses requests are maybe hitting your main heavy application, generating slow http queries and preventing regular users to acces your apache processes. They are generated on graceful reload or children managment.
If you do not have a simple basic "It works" default Virtualhost prevent theses requests on your application by some rewrites:
RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
RewriteRule .* - [F,L]
Update:
Having only one Virtualhost does not protect you from internal dummy connections, it is worst, you are sure now that theses connections are made on your unique Virtualhost. So you should really avoid side effects on your application by using the rewrite rules.
Reading your cacti graphics, it seems your apache is not in prefork mode bug in worker mode. Run httpd -l
or apache2 -l
on debian, and check if you have worker.c or prefork.c. If you are in worker mode you may encounter some PHP problems in your application, but you should check the worker settings, here is an example:
<IfModule worker.c>
StartServers 3
MaxClients 500
MinSpareThreads 75
MaxSpareThreads 250
ThreadsPerChild 25
MaxRequestsPerChild 300
</IfModule>
You start 3 processes, each containing 25 threads (so 3*25=75 parallel requests available by default), you allow 75 threads doing nothing, as soon as one thread is used a new process is forked, adding 25 more threads. And when you have more than 250 threads doing nothing (10 processes) some process are killed. You must adjust theses settings with your memory. Here you allow 500 parallel process (that's 20 process of 25 threads). Your usage is maybe more:
<IfModule worker.c>
StartServers 2
MaxClients 250
MinSpareThreads 50
MaxSpareThreads 150
ThreadsPerChild 25
MaxRequestsPerChild 300
</IfModule>

For me follwing steps helped.
It seems to be bug of Android Studio 3.4/3.5 and it was "fixed" by disabling:

// removing the viewcontrollers by class names from stack and then dismissing the current view.

if vc.isKind(of: ViewController.self) || vc.isKind(of: ViewController2.self)

You can only use await
in an async
method, and Main
cannot be async
.
You'll have to use your own async
-compatible context, call Wait
on the returned Task
in the Main
method, or just ignore the returned Task
and just block on the call to Read
. Note that Wait
will wrap any exceptions in an AggregateException
.
If you want a good intro, see my async
/await
intro post.
You remove the original image here:
newImg.animate(css, SPEED, function() {
img.remove();
newImg.removeClass('morpher');
(callback || function() {})();
});
And all that's left behind is newImg
. Then you reset link references the image using #rocket
:
$("#rocket").attr('src', ...
But your newImg
doesn't have an id
attribute let alone an id
of rocket
.
To fix this, you need to remove img
and then set the id
attribute of newImg
to rocket
:
newImg.animate(css, SPEED, function() {
var old_id = img.attr('id');
img.remove();
newImg.attr('id', old_id);
newImg.removeClass('morpher');
(callback || function() {})();
});
And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/
UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:
$("#resetlink").click(function(){
clearInterval(timerRocket);
$("#wrapper").css('top', '250px');
$('.throbber, .morpher').remove(); // Clear out the new stuff.
$("#rocket").show(); // Bring the original back.
});
And in the newImg.load
function, grab the images original size:
var orig = {
width: img.width(),
height: img.height()
};
And finally, the callback for finishing the morphing animation becomes this:
newImg.animate(css, SPEED, function() {
img.css(orig).hide();
(callback || function() {})();
});
New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/
The leaking of $('.throbber, .morpher')
outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.
TryGetValue is slightly faster, because FindEntry will only be called once.
How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.
FYI: It's not actually catching an error.
It's calling:
public bool TryGetValue(TKey key, out TValue value)
{
int index = this.FindEntry(key);
if (index >= 0)
{
value = this.entries[index].value;
return true;
}
value = default(TValue);
return false;
}
ContainsKey is this:
public bool ContainsKey(TKey key)
{
return (this.FindEntry(key) >= 0);
}
You can simply pass the functions as a list:
In [20]: df.groupby("dummy").agg({"returns": [np.mean, np.sum]})
Out[20]:
mean sum
dummy
1 0.036901 0.369012
or as a dictionary:
In [21]: df.groupby('dummy').agg({'returns':
{'Mean': np.mean, 'Sum': np.sum}})
Out[21]:
returns
Mean Sum
dummy
1 0.036901 0.369012
You can use function: wc_get_page_id( 'cart' ) to get the ID of the page. This function will use the page setup as 'cart' page and not the slug. Meaning it will keep working also when you setup a different url for your 'cart' on the settings page. This works for all kind of Woocommerce special page, like 'checkout', 'shop' etc.
example:
if (wc_get_page_id( 'cart' ) == get_the_ID()) {
// Do something.
}
What about using the following:
int number = input.nextInt();
if (number < 0) {
// negative
} else {
// it's a positive
}
is that you can make Apache (www-data)
, the owner of the folder
sudo chown -R www-data:www-data /var/www
that should make file_put_contents
work now. But for more security you better also set the permissions like below
find /var/www -type d -print0 | xargs -0 chmod 0755 # folder
find /var/www -type f -print0 | xargs -0 chmod 0644 # files
/var/www
to the root folder of your php filesRecently I learned of the following syntax:
DELETE (SELECT *
FROM productfilters pf
INNER JOIN product pr
ON pf.productid = pr.id
WHERE pf.id >= 200
AND pr.NAME = 'MARK')
I think it looks much cleaner then other proposed code.
Can use this add condition.
<el-form-item :label="Amount ($)" style="width:100%" >
<template slot-scope="scoped">
<el-input-number v-model="listQuery.refAmount" :disabled="(rowData.status !== 1 ) === true" ></el-input-number>
</template>
</el-form-item>
I had the same issue and found out that my code was using the injection before it was initialized.
services.AddControllers(); // Will cause a problem if you use your IBloggerRepository in there since it's defined after this line.
services.AddScoped<IBloggerRepository, BloggerRepository>();
I know it has nothing to do with the question, but since I was sent to this page, I figure out it my be useful to someone else.
Yes, use getScript instead of document.write - it will even allow for a callback once the file loads.
You might want to check if TinyMCE is defined, though, before including it (for subsequent calls to 'Add Comment') so the code might look something like this:
$('#add_comment').click(function() {
if(typeof TinyMCE == "undefined") {
$.getScript('tinymce.js', function() {
TinyMCE.init();
});
}
});
Assuming you only have to call init
on it once, that is. If not, you can figure it out from here :)
Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...
PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));
So it will return false when the method is called in same test case and then it will return false again and lastly true.
The accepted answer is great, however this can be done with flexbox
.
Here's a grid system written with BEM syntax that allows for 1-10 columns to be displayed per row.
If there the last row is incomplete (for example you choose to show 5 cells per row and there are 7 items), the trailing items will be centered horizontally. To control the horizontal alignment of the trailing items, simply change the justify-content
property under the .square-grid
class.

This is tested in FF and Chrome.
Using moment.js as you asked, there is a unix
method that accepts unix timestamps in seconds:
var dateString = moment.unix(value).format("MM/DD/YYYY");
Try something like this - it works for the cases you have mentioned.
select * from tbl
where answer like '%[0-9]%'
and answer not like '%[:]%'
and answer not like '%[A-Z]%'
This should work but must be used within an unsafe context:
byte[] buffer = new byte[255];
fixed (byte* p = buffer)
{
IntPtr ptr = (IntPtr)p;
// do you stuff here
}
beware, you have to use the pointer in the fixed block! The gc can move the object once you are not anymore in the fixed block.
Using simple html,
<div>
<object type="text/html" data="http://validator.w3.org/" width="800px" height="600px" style="overflow:auto;border:5px ridge blue">
</object>
</div>
Or jquery,
<script>
$("#mydiv")
.html('<object data="http://your-website-domain"/>');
</script>
To get the public key you can simply do:
public static PublicKey getPublicKeyFromCertFile(final String certfile){
return new X509CertImpl(new FileInputStream(new File(certfile))).getPublicKey();
To get the private key is trickier, you can:
public static PrivateKey getPrivateKeyFromKeyFile(final String keyfile){
try {
Process p;
p = Runtime.getRuntime().exec("openssl pkcs8 -nocrypt -topk8 -inform PEM " +
"-in " + keyfile + " -outform DER -out " + keyfile + ".der");
p.waitFor();
System.out.println("Command executed" + (p.exitValue() == 0 ? " successfully" : " with error" ));
} catch ( IOException | InterruptedException e) {
e.printStackTrace();
System.exit(1);
}
PrivateKey myPrivKey = null;
try {
byte[] keyArray = Files.readAllBytes(Paths.get(keyfile + ".der"));
PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(keyArray);
KeyFactory keyFactory = KeyFactory.getInstance("RSA");
myPrivKey = keyFactory.generatePrivate(keySpec);
} catch (IOException | NoSuchAlgorithmException | InvalidKeySpecException e){
e.printStackTrace();
System.exit(1);
}
return myPrivKey;

A good reason is for security - this can prevent CSRF attacks because this header cannot be added to the AJAX request cross domain without the consent of the server via CORS.
Only the following headers are allowed cross domain:
- Accept
- Accept-Language
- Content-Language
- Last-Event-ID
- Content-Type
any others cause a "pre-flight" request to be issued in CORS supported browsers.
Without CORS it is not possible to add X-Requested-With
to a cross domain XHR request.
If the server is checking that this header is present, it knows that the request didn't initiate from an attacker's domain attempting to make a request on behalf of the user with JavaScript. This also checks that the request wasn't POSTed from a regular HTML form, of which it is harder to verify it is not cross domain without the use of tokens. (However, checking the Origin
header could be an option in supported browsers, although you will leave old browsers vulnerable.)
You may wish to combine this with a token, because Flash running on Safari on OSX can set this header if there's a redirect step. It appears it also worked on Chrome, but is now remediated. More details here including different versions affected.
OWASP Recommend combining this with an Origin and Referer check:
This defense technique is specifically discussed in section 4.3 of Robust Defenses for Cross-Site Request Forgery. However, bypasses of this defense using Flash were documented as early as 2008 and again as recently as 2015 by Mathias Karlsson to exploit a CSRF flaw in Vimeo. But, we believe that the Flash attack can't spoof the Origin or Referer headers so by checking both of them we believe this combination of checks should prevent Flash bypass CSRF attacks. (NOTE: If anyone can confirm or refute this belief, please let us know so we can update this article)
However, for the reasons already discussed checking Origin can be tricky.
Written a more in depth blog post on CORS, CSRF and X-Requested-With here.

len
is a built-in function that calls the given container object's __len__
member function to get the number of elements in the object.
Functions encased with double underscores are usually "special methods" implementing one of the standard interfaces in Python (container, number, etc). Special methods are used via syntactic sugar (object creation, container indexing and slicing, attribute access, built-in functions, etc.).
Using obj.__len__()
wouldn't be the correct way of using the special method, but I don't see why the others were modded down so much.
If you have committed changes to master branch. Now you want to move that same commit to release-branch. Check the commit id(Eg:xyzabc123) for the commit.
Now try following commands
git checkout release-branch
git cherry-pick xyzabc123
git push origin release-branch
On linux, create file in /etc/default/locale
with the following contents
LANG=en.utf8
and then use the source
command to export this variable by running
source /etc/default/locale
The source command sets the variable permanently.
You probably want to have a list of supported encodings. For each file, try each encoding in turn, maybe starting with UTF-8. Every time you catch the MalformedInputException
, try the next encoding.
Just use the -H
parameter several times:
curl -H "Accept-Charset: utf-8" -H "Content-Type: application/x-www-form-urlencoded" http://www.some-domain.com
I got this same error when installing to an actual device. More information and a solution to loading the missing libraries to the device can be found at the following site:

To set this up correctly, there are 2 key files that need to be copied to the system:
com.google.android.maps.xml
com.google.android.maps.jar
These files are located in the any of these google app packs:
http://android.d3xt3...0120-signed.zip
http://goo-inside.me...0120-signed.zip
http://android.local...0120-signed.zip
These links no longer work, but you can find the files in the android sdk if you have Google Maps API v1
After unzipping any of these files, you want to copy the files to your system, like-ah-so:
adb remount
adb push system/etc/permissions/com.google.android.maps.xml /system/etc/permissions
adb push system/framework/com.google.android.maps.jar /system/framework
adb reboot
For me, the problem was trying to pass a filename in a url, with a dot. For example
"http://localhost:8080/something/asdf.jpg" //causes error because of '.jpg'
It could be solved by not passing the .jpg extension, or sending it all in a request body.
Have a look at the error - 'log4j:ERROR setFile(null,false) call failed. java.io.FileNotFoundException: logs (Access is denied)'
It seems there's a log file named as 'logs' to which access is denied i.e it is not having sufficient permissions to write logs. Try by giving write permissions to the 'logs' log file. Hope it helps.
One could use the queryParam method, passing it parameter name and an array of values:
public WebTarget queryParam(String name, Object... values);
Example (jersey-client 2.23.2):
WebTarget target = ClientBuilder.newClient().target(URI.create("http://localhost"));
target.path("path")
.queryParam("param_name", Arrays.asList("paramVal1", "paramVal2").toArray())
.request().get();
This will issue request to following URL:
http://localhost/path?param_name=paramVal1¶m_name=paramVal2
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.
There should be svn
utility on you box, if installed:
$ svn checkout http://example.com/svn/somerepo somerepo
This will check out a working copy from a specified repository to a directory somerepo
on our file system.
You may want to print commands, supported by this utility:
$ svn help
uname -a
output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm
or the following command:
$ sudo yum install subversion
Stopwatch is fine, but loop the work 10^6 times, then divide by 10^6. You'll get a lot more precision.
What we didn't do right was to not apply with the accurate code when signing in the Build Settings. We fixed the issue up this way: Enter into Build Settings >> Code Signing >> Code Sign Identity. Then, apply with your iOS Developer ID for 'Debug', but be sure to apply with your iOS Distribution Profile for 'Release' We didn't apply correctly, so we couldn't have permission to ask for the App from the server, actually. Anyway this post forced us to revise all the parameters and requirements, so we pretty appreciate all your answers. Regards, T.

you did not use S anywhere in your algorithm (besides modifying it). the idea of dijkstra is once a vertex is on S, it will not be modified ever again. in this case, once B is inside S, you will not reach it again via C.
this fact ensures the complexity of O(E+VlogV) [otherwise, you will repeat edges more then once, and vertices more then once]
in other words, the algorithm you posted, might not be in O(E+VlogV), as promised by dijkstra's algorithm.

Full version:
<? echo date('F Y'); ?>
Short version:
<? echo date('M Y'); ?>
Here is a good reference for the different date options.
update
To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp
parameter for the date() function. Like this:
echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));
This will also work (it's typically used to get the last day of the previous month):
echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));
Hope that helps.
Since 2.3 version of Gson library the JsonArray class have a 'set' method.
Here's an simple example:
JsonArray array = new JsonArray();
array.add(new JsonPrimitive("Red"));
array.add(new JsonPrimitive("Green"));
array.add(new JsonPrimitive("Blue"));
array.remove(2);
array.set(0, new JsonPrimitive("Yelow"));
Try this - Write on Manifest:
uses-permission android:name="android.permission.INSTALL_PACKAGES"
tools:ignore="ProtectedPermissions"
Write the Code:
File sdCard = Environment.getExternalStorageDirectory();
String fileStr = sdCard.getAbsolutePath() + "/Download";// + "app-release.apk";
File file = new File(fileStr, "app-release.apk");
Intent promptInstall = new Intent(Intent.ACTION_VIEW).setDataAndType(Uri.fromFile(file),
"application/vnd.android.package-archive");
startActivity(promptInstall);
Frankly, I can't find a single reason to use MySQL rather than MSSQL. The issue before used to be cost but SQL Server 2005 Express is free and there are lots of web hosting companies which offer full hosting with sql server for less than $5.00 a month.
MSSQL is easier to use and has many features which do not exist in MySQL.
& is used in PHP to pass an object to a method / assign a new object to a variable by reference. It is deprecated in PHP 5 because PHP 5 passes all objects by reference by default.
SIGINT can be send to program using windows-kill, by syntax windows-kill -SIGINT PID
, where PID
can be obtained by Microsoft's pslist.
Regarding catching SIGINTs, if your program is in Python then you can implement SIGINT processing/catching like in this solution.
.text()
will give you the actual text in between HTML tags. For example, the paragraph text in between p
tags. What is interesting to note is that it will give you all the text in the element you are targeting with with your $
selector plus all the text in the children elements of that selected element. So If you have multiple p
tags with text inside the body element and you do a $(body).text()
, you will get all the text from all the paragraphs. (Text only, not the p
tags themselves.)
.html()
will give you the text and the tags. So $(body).html()
will basically give you your entire page HTML page
.val()
works for elements that have a value
attribute, such as input
.
An input
does not have contained text or HTML and thus .text()
and .html()
will both be null
for input
elements.
You're mixing if statement with a ternary expression, that's why you're having a syntax error. It might be easier for you to understand what's going on if you extract mapping function outside of your render method:
renderItem = (id) => {
// just standard if statement
if (this.props.schema.collectionName.length < 0) {
return (
<Expandable>
<ObjectDisplay
key={id}
parentDocumentId={id}
schema={schema[this.props.schema.collectionName]}
value={this.props.collection.documents[id]}
/>
</Expandable>
);
}
return (
<h1>hejsan</h1>
);
}
Then just call it when mapping:
render() {
return (
<div>
<div className="box">
{
this.props.collection.ids
.filter(
id =>
// note: this is only passed when in top level of document
this.props.collection.documents[id][
this.props.schema.foreignKey
] === this.props.parentDocumentId
)
.map(this.renderItem)
}
</div>
</div>
)
}
Of course, you could have used the ternary expression as well, it's a matter of preference. What you use, however, affects the readability, so make sure to check different ways and tips to properly do conditional rendering in react and react native.
I can't replicate that (php 5.3.6):
php > $error = array();
php > $error['something'] = false;
php > $error['somethingelse'] = false;
php > var_dump(empty($error));
bool(false)
php > $error = array();
php > var_dump(empty($error));
bool(true)
php >
exactly where are you doing the empty()
call that returns true?
Just a tip.. Temporary tables in Oracle are different to SQL Server. You create it ONCE and only ONCE, not every session. The rows you insert into it are visible only to your session, and are automatically deleted (i.e., TRUNCATE
, not DROP
) when you end you session ( or end of the transaction, depending on which "ON COMMIT" clause you use).
Use ===
to equate the variables instead of ==
.
==
checks if the value of the variables is similar
===
checks if the value of the variables and the type of the variables are similar
Notice how
if(0===false) {
document.write("oh!!! that's true");
}?
and
if(0==false) {
document.write("oh!!! that's true");
}?
give different results
I found the solution:
In your activity which has the Theme.Dialog
style set, do this:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}
It's important that you call Window.setLayout()
after you call setContentView()
, otherwise it won't work.
You have several errors there.
First, you have to return a value from the function in the HTML markup: <form name="ff1" method="post" onsubmit="return validateForm();">
Second, in the JSFiddle, you place the code inside onLoad which and then the form won't recognize it - and last you have to return true from the function if all validation is a success - I fixed some issues in the update:
https://jsfiddle.net/mj68cq0b/
function validateURL(url) {
var reurl = /^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/;
return reurl.test(url);
}
function validateForm()
{
// Validate URL
var url = $("#frurl").val();
if (validateURL(url)) { } else {
alert("Please enter a valid URL, remember including http://");
return false;
}
// Validate Title
var title = $("#frtitle").val();
if (title=="" || title==null) {
alert("Please enter only alphanumeric values for your advertisement title");
return false;
}
// Validate Email
var email = $("#fremail").val();
if ((/(.+)@(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email==null) { } else {
alert("Please enter a valid email");
return false;
}
return true;
}
You cannot use IF control block OUTSIDE of functions. So that affects both of your queries.
Turn the EXISTS clause into a subquery instead within an IF function
SELECT IF( EXISTS(
SELECT *
FROM gdata_calendars
WHERE `group` = ? AND id = ?), 1, 0)
In fact, booleans are returned as 1 or 0
SELECT EXISTS(
SELECT *
FROM gdata_calendars
WHERE `group` = ? AND id = ?)
If you are using PHP, try using <?php flush(); ?>
after </head>
and before </body>
or whatever section you want to output quickly (like the header or content). It will output the actually code without waiting for php to end. Don't use this function all the time, or the speed increase won't be noticable.
One of The Shortest method i found for single value while i was searching for myself, is just passing single string and setting string as model in view like this.
In your Partial calling side
@Html.Partial("ParitalAction", "String data to pass to partial")
And then binding the model with Partial View like this
@model string
and the using its value in Partial View like this
@Model
You can also play with other datatypes like array, int or more complex data types like IDictionary or something else.
Hope it helps,
None of the css trick worked for me (in my case the fb-like box was pulled right with "float:right"). However, what worked without any additional tricks is an IFRAME version of the button code. I.e.:
<iframe src="//www.facebook.com/plugins/like.php?href=..."
scrolling="no" frameborder="0"
style="border:none; overflow:hidden; width:71px; height:21px;"
allowTransparency="true">

(Note custom width in style, and no need to include additional javascript.)

SQL*Plus uses &1, &2... &n to access the parameters.
Suppose you have the following script test.sql
:
SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off
you could call this script like this for example:
$ sqlplus login/pw @test Hello World!
In a UNIX script you would usually call a SQL script like this:
sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF
so that your login/password won't be visible with another session's ps
Peters' python 2 workaround fails on an edge case:
d = {u'keyword': u'bad credit \xe7redit cards'}
with io.open('filename', 'w', encoding='utf8') as json_file:
data = json.dumps(d, ensure_ascii=False).decode('utf8')
try:
json_file.write(data)
except TypeError:
# Decode data to Unicode first
json_file.write(data.decode('utf8'))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe7' in position 25: ordinal not in range(128)
It was crashing on the .decode('utf8') part of line 3. I fixed the problem by making the program much simpler by avoiding that step as well as the special casing of ascii:
with io.open('filename', 'w', encoding='utf8') as json_file:
data = json.dumps(d, ensure_ascii=False, encoding='utf8')
json_file.write(unicode(data))
cat filename
{"keyword": "bad credit çredit cards"}
In your code j is Already json data and j['places'] is list not dict.
r = requests.get('http://api.zippopotam.us/us/ma/belmont')
j = r.json()
print j['state']
for each in j['places']:
print each['latitude']
You can use the spool
command (SQL*Plus documentation, but one of many such commands SQL Developer also supports) to write results straight to disk. Each spool
can change the file that's being written to, so you can have several queries writing to different files just by putting spool
commands between them:
spool "\path\to\spool1.txt"
select /*csv*/ * from employees;
spool "\path\to\spool2.txt"
select /*csv*/ * from locations;
spool off;
You'd need to run this as a script (F5, or the second button on the command bar above the SQL Worksheet). You might also want to explore some of the formatting options and the set
command, though some of those do not translate to SQL Developer.
Since you mentioned CSV in the title I've included a SQL Developer-specific hint that does that formatting for you.
A downside though is that SQL Developer includes the query in the spool file, which you can avoid by having the commands and queries in a script file that you then run as a script.
I would do something like,
Main
var getPage = get_page
func get_page (...
func downloader() {
dl_slots = make(chan bool, DL_SLOT_AMOUNT) // Init the download slot semaphore
content := getPage(BASE_URL)
links_regexp := regexp.MustCompile(LIST_LINK_REGEXP)
matches := links_regexp.FindAllStringSubmatch(content, -1)
for _, match := range matches{
go serie_dl(match[1], match[2])
}
}
Test
func TestDownloader (t *testing.T) {
origGetPage := getPage
getPage = mock_get_page
defer func() {getPage = origGatePage}()
// The rest to be written
}
// define mock_get_page and rest of the codes
func mock_get_page (....
And I would avoid _
in golang. Better use camelCase
As per RFC2368 which defines mailto:
, further reinforced by an example in RFC1738, it is explicitly stated that the only valid way to generate a line break is with %0D%0A
.
This also applies to all url schemes such as gopher, smtp, sdp, imap, ldap, etc..
Maybe this might work:
Sh.Range("A1", Sh.Range("A" & Rows.Count).End(xlUp))
It is a server error, not a client error. If server errors weren't to be returned to the client, there wouldn't have been created an entire status code class for them (i.e. 5xx).
You can't hide the fact that you either made a programming error or some service you rely on is unavailable, and that certainly isn't the client's fault. Returning any other range of code in those cases than the 5xx series would make no sense.
RFC 7231 mentions in section 6.6. Server Error 5xx:
The 5xx (Server Error) class of status code indicates that the server is aware that it has erred or is incapable of performing the requested method.
This is exactly the case. There's nothing "internal" about the code "500 Internal Server Error" in the sense that it shouldn't be exposed to the client.
As far as the themes, VS Code is every bit as editable as Sublime. You can edit any of the default themes that come with VS code. You just have to know where to find the theme files.
Side note: I love the Monokai theme. However, all I wanted to change about it was the background. I don't like the dark grayish background. Instead, I think the contrast is WAY better with a solid black background. The code pops out much more.
Anyways, I hunted for the theme file and found it (in windows) at:
c:\Program Files (x86)\Microsoft VS Code\resources\app\extensions\theme-monokai\themes\
In that folder I found the Monokai.tmTheme file and modified the first background key as follows:
<key>background</key>
<string>#000000</string>
There are a few 'background' key in the theme file, make sure you edit the correct one. The one I edited was at the very top. Line 12 I think.
The snippet here works fine, tested with windows sound:
public static void main(String[] args) {
AePlayWave aw = new AePlayWave( "C:\\WINDOWS\\Media\\tada.wav" );
aw.start();
}
The opposite of :hover
appears to be :link
.
(edit: not technically an opposite because there are 4 selectors :link
, :visited
, :hover
and :active
. Five if you include :focus
.)
For example when defining a rule .button:hover{ text-decoration:none }
to remove the underline on a button, the underline shows up when you roll off the button in some browsers. I've fixed this with .button:hover, .button:link{ text-decoration:none }
This of course only works for elements that are actually links (have href attribute)

Although for Razor you can of course just generate the options by looping through TimeZoneInfo.GetSystemTimeZones()
Simple solution:
git init
git add =A
git commit -m "your commit"
git push -u origin master
if you want add folder to existing repo ..then add folder to local project code
git rm --cached ./folderName
git add ./folderName
after that
git status
git commit -m "your commit"
git push -u origin master
users=("kamal" "jamal" "rahim" "karim" "sadia")
index=()
t=-1
for i in ${users[@]}; do
t=$(( t + 1 ))
if [ $t -eq 0 ]; then
for j in ${!users[@]}; do
index[$j]=$j
done
fi
echo "${index[$t]} is $i"
done
try yo write document.getElementById('id').style.visibility="hidden";

I'd recommend using some work queue using, for example, the excellent Gearman, which will provide you with a great way to dispatch background jobs, and asynchronously get their result once they're processed.
The advantage of this, used heavily at Digg (among many others) is that it provides a strong, scalable and robust way to make workers in any language to speak with clients in any language.
You can go through the following link as it helped me, should work for you as well. http://hype-free.blogspot.com/2007/07/updating-php-in-xampp-for-windows.html
Realizing that my answer helped couple of users, here is the edit from original link:
Edit:
NOTE: there are two directories to be updated with new version of files, namely php
sub-directory and apache/bin
sub-directory, inside XAMPP installation.
I prefer using String Interpolation
let x = 45
let string = "\(x)"
Each object has some string representation. This makes things simpler. For example if you need to create some String
with multiple values. You can also do any math in it or use some conditions
let text = "\(count) \(count > 1 ? "items" : "item") in the cart. Sum: $\(sum + shippingPrice)"
Just declare it outside class definition.
If your namespace's name is X, you will be able to access the enum's values by X.card_suit
If you have not defined a namespace for this enum, just call them by card_suit.Clubs etc.
Adding a 1px transparent border will trigger anti-aliasing
outline: 1px solid transparent;
Alternatively, add a 1px transparent box-shadow.
box-shadow: 0 0 1px rgba(255,255,255,0);
It is often required to move both body and html objects together.
$('html,body').animate({
scrollTop: $("#divToBeScrolledTo").offset().top
});
ShiftyThomas is right:
$("#divToBeScrolledTo").offset().top + 10 // +10 (pixels) reduces the margin.
So to increase the margin use:
$("#divToBeScrolledTo").offset().top - 10 // -10 (pixels) would increase the margin between the top of your window and your element.
Here is:
var array : [String] = ["One", "Two", "Three"]
let userDefault = UserDefaults.standard
// set
userDefault.set(array, forKey: "array")
// retrieve
if let fetchArray = userDefault.array(forKey: "array") as? [String] {
// code
}
when you are dealing with popups window.opener plays an important role, because we have to deal with fields of parent page as well as child page, when we have to use values on parent page we can use window.opener or we want some data on the child window or popup window at the time of loading then again we can set the values using window.opener
You can submit form by just clicking on checkbox by simple method in JavaScript. Inside form tag or Input attribute add following attribute:
onchange="this.form.submit()"
Example:
<form>
<div>
<input type="checkbox">
</div>
</form>
There seems to be some confusion over how to get this set up for the Express version specifically. Using the Windows Desktop (WD) version of VS Express 2012, I followed the instructions in Steve B's and Rick Martin's answers with the modifications below.
"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0"
, copy to "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\WDExpressExtensions\Microsoft\XNA Game Studio 4.0"
<Edition>WDExpress</Edition>
(you should be able to see where it makes sense)devenv.exe
with WDExpress.exe
"%LocalAppData%\Microsoft\VisualStudio\11.0\Extensions"
with "%LocalAppData%\Microsoft\WDExpress\11.0\Extensions"
I haven't done a lot of work since then, but I did manage to create a new game project and it seems fine so far.
I eventually used:
weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)
It worked just fine, except that I got the following message.
C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated. Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.
You want
$ jar cvf asd.jar .
to specify the directory (e.g. .
) to jar
from. That will maintain your folder structure within the jar file.
Regarding the question,
” can someone explain why the
compare()
function exists if a comparison can be made using simple operands?
Relative to <
and ==
, the compare
function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.
As an example of simplicity, for small integer values you can write a compare function like this:
auto compare( int a, int b ) -> int { return a - b; }
which is highly efficient.
Now for a structure
struct Foo
{
int a;
int b;
int c;
};
auto compare( Foo const& x, Foo const& y )
-> int
{
if( int const r = compare( x.a, y.a ) ) { return r; }
if( int const r = compare( x.b, y.b ) ) { return r; }
return compare( x.c, y.c );
}
Trying to express this lexicographic compare directly in terms of <
you wind up with horrendous complexity and inefficiency, relatively speaking.
With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.
That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).
Just note to anyone trying the REGEXP to use "LIKE IN" functionality.
IN allows you to do:
field IN (
'val1',
'val2',
'val3'
)
In REGEXP this won't work
REGEXP '
val1$|
val2$|
val3$
'
It has to be in one line like this:
REGEXP 'val1$|val2$|val3$'
Well, why not just add them to your existing character class?
var pattern = /[a-zA-Z0-9&._-]/
If you need to check whether a string consists of nothing but those characters you have to anchor the expression as well:
var pattern = /^[a-zA-Z0-9&._-]+$/
The added ^
and $
match the beginning and end of the string respectively.
Testing for letters, numbers or underscore can be done with \w
which shortens your expression:
var pattern = /^[\w&.-]+$/
As mentioned in the comment from Nathan, if you're not using the results from .match()
(it returns an array with what has been matched), it's better to use RegExp.test()
which returns a simple boolean:
if (pattern.test(qry)) {
// qry is non-empty and only contains letters, numbers or special characters.
}
Update 2
In case I have misread the question, the below will check if all three separate conditions are met.
if (/[a-zA-Z]/.test(qry) && /[0-9]/.test(qry) && /[&._-]/.test(qry)) {
// qry contains at least one letter, one number and one special character
}
How to use Hex Color Code #b74093 in Flutter
Simply remove the # sign from hex color code and ad 0xff with color code inside Color class
#b74093
will become Color(0xffb74093)
in Flutter
#B74093
will become Color(0xFFB74093)
in Flutter
the ff or FF
in Color(0xFFB74093)
defines the opacity
If you're looking at using this for relative timing (for example for games or animation) I'd rather use CACurrentMediaTime()
double CurrentTime = CACurrentMediaTime();
Which is the recommended way; NSDate
draws from the networked synch-clock and will occasionally hiccup when re-synching it against the network.
It returns the current absolute time, in seconds.
If you want only the decimal part (often used when syncing animations),
let ct = CACurrentMediaTime().truncatingRemainder(dividingBy: 1)
I you are using Visual Studio 2012, download and install Update 2 that Microsoft released recently (as of 4/2013).
There are some bug fixes in that update related to the issue.
Please check the query without using a function:
declare @T table(Insurance varchar(max))
insert into @T values ('wezembeek-oppem')
insert into @T values ('roeselare')
insert into @T values ('BRUGGE')
insert into @T values ('louvain-la-neuve')
select (
select upper(T.N.value('.', 'char(1)'))+
lower(stuff(T.N.value('.', 'varchar(max)'), 1, 1, ''))+(CASE WHEN RIGHT(T.N.value('.', 'varchar(max)'), 1)='-' THEN '' ELSE ' ' END)
from X.InsXML.nodes('/N') as T(N)
for xml path(''), type
).value('.', 'varchar(max)') as Insurance
from
(
select cast('<N>'+replace(
replace(
Insurance,
' ', '</N><N>'),
'-', '-</N><N>')+'</N>' as xml) as InsXML
from @T
) as X
You messed up the second part of your if
condition. That should be a <= 90
.
Also, FYI, there is a C library function tolower
that does this already:
#include <ctype.h>
#include <stdio.h>
int main() {
putchar(tolower('A'));
}

There is another solution if you want to develop in C/C++. http://www.DragonFireSDK.com will allow you to build iPhone applications in Visual Studio on Windows. It's worth a look-see for sure.
U can define a method to building a Compound string key every where u want to using dictionary u must using this method to build your key for example:
private string keyBuilder(int key1, int key2)
{
return string.Format("{0}/{1}", key1, key2);
}
for using:
myDict.ContainsKey(keyBuilder(key1, key2))
I don't know what you mean by 'manually'. You can choose a colourmap and make a colour array easily enough:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm
x = np.arange(10)
ys = [i+x+(i*x)**2 for i in range(10)]
colors = cm.rainbow(np.linspace(0, 1, len(ys)))
for y, c in zip(ys, colors):
plt.scatter(x, y, color=c)
Or you can make your own colour cycler using itertools.cycle
and specifying the colours you want to loop over, using next
to get the one you want. For example, with 3 colours:
import itertools
colors = itertools.cycle(["r", "b", "g"])
for y in ys:
plt.scatter(x, y, color=next(colors))
Come to think of it, maybe it's cleaner not to use zip
with the first one neither:
colors = iter(cm.rainbow(np.linspace(0, 1, len(ys))))
for y in ys:
plt.scatter(x, y, color=next(colors))
Why not just using CSS's filter
property to manipulate the color on :hover
or whatever other state? I found it works over SVG images into img
tags. At least, it's almost fully supported in 2020. It seams to me the simpliest solution. The only caveat is having to tweak the filter properties in order to find the target color. But you have also this very useful tool.
You need to add a TraceListener
to see them appear on the Console.
TextWriterTraceListener writer = new TextWriterTraceListener(System.Console.Out);
Debug.Listeners.Add(writer);
They also appear in the Visual Studio Output window when in Debug mode.
You should be able to use chaining to execute the events in sequence, e.g.:
$('#target')
.bind('click',function(event) {
alert('Hello!');
})
.bind('click',function(event) {
alert('Hello again!');
})
.bind('click',function(event) {
alert('Hello yet again!');
});
I guess the below code is doing the same
$('#target')
.click(function(event) {
alert('Hello!');
})
.click(function(event) {
alert('Hello again!');
})
.click(function(event) {
alert('Hello yet again!');
});
Source: http://www.peachpit.com/articles/article.aspx?p=1371947&seqNum=3
TFM also says:
When an event reaches an element, all handlers bound to that event type for the element are fired. If there are multiple handlers registered, they will always execute in the order in which they were bound. After all handlers have executed, the event continues along the normal event propagation path.
You could try the following:
import matplotlib.pyplot as plt
import numpy as np
def plot_figures(figures, nrows = 1, ncols=1):
"""Plot a dictionary of figures.
Parameters
----------
figures : <title, figure> dictionary
ncols : number of columns of subplots wanted in the display
nrows : number of rows of subplots wanted in the figure
"""
fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
for ind,title in zip(range(len(figures)), figures):
axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
axeslist.ravel()[ind].set_title(title)
axeslist.ravel()[ind].set_axis_off()
plt.tight_layout() # optional
# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}
# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)
plt.show()
However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.
I hope this helps.
I had a problem with the answer by @mwaskorn, namely that
g.set_xticklabels(rotation=30)
fails, because this also requires the labels. A bit easier than the answer by @Aman is to just add
plt.xticks(rotation=45)
I have in my config two aliases:
alias.foo=commit -a -m 'none'
alias.coa=commit -a -m
if I am too lazy I just commit all changes with
git foo
and just to do a quick commit
git coa "my changes are..."
coa stands for "commit all"
I've found none of the suggestions to really work. Here's a more robust one that normalizes spacing when finding classes.
//Inside closure so that the inner functions don't need regeneration on every call.
const getCssClasses = (function () {
function normalize(str) {
if (!str) return '';
str = String(str).replace(/\s*([>~+])\s*/g, ' $1 '); //Normalize symbol spacing.
return str.replace(/(\s+)/g, ' ').trim(); //Normalize whitespace
}
function split(str, on) { //Split, Trim, and remove empty elements
return str.split(on).map(x => x.trim()).filter(x => x);
}
function containsAny(selText, ors) {
return selText ? ors.some(x => selText.indexOf(x) >= 0) : false;
}
return function (selector) {
const logicalORs = split(normalize(selector), ',');
const sheets = Array.from(window.document.styleSheets);
const ruleArrays = sheets.map((x) => Array.from(x.rules || x.cssRules || []));
const allRules = ruleArrays.reduce((all, x) => all.concat(x), []);
return allRules.filter((x) => containsAny(normalize(x.selectorText), logicalORs));
};
})();
Here's it in action from the Chrome console.
Today, you could try editorconfig, there is also a vim plugin for it. With this, you are able not only change indentation size in vim, but in many other editors, keep consistent coding styles.
Below is a simple editorconfig, as you can see, the python files will have 4 spaces for indentation, and pug template files will only have 2.
# 4 space indentation for python files
[*.py]
indent_style = space
indent_size = 4
# 2 space indentation for pug templates
[*.pug]
indent_size = 2
that’s just wrong: is not a wrapper. The element denotes a semantic section of your content to help construct a document outline. It should contain a heading. If you’re looking for a page wrapper element (for any flavour of HTML or XHTML), consider applying styles directly to the element as described by Kroc Camen. If you still need an additional element for styling, use a . As Dr Mike explains, div isn’t dead, and if there’s nothing else more appropriate, it’s probably where you really want to apply your CSS.

Cascade will work when you delete something on table Courses
. Any record on table BookCourses
that has reference to table Courses
will be deleted automatically.
But when you try to delete on table BookCourses
only the table itself is affected and not on the Courses
follow-up question: why do you have CourseID
on table Category?
Maybe you should restructure your schema into this,
CREATE TABLE Categories
(
Code CHAR(4) NOT NULL PRIMARY KEY,
CategoryName VARCHAR(63) NOT NULL UNIQUE
);
CREATE TABLE Courses
(
CourseID INT NOT NULL PRIMARY KEY,
BookID INT NOT NULL,
CatCode CHAR(4) NOT NULL,
CourseNum CHAR(3) NOT NULL,
CourseSec CHAR(1) NOT NULL,
);
ALTER TABLE Courses
ADD FOREIGN KEY (CatCode)

I had this problem for a long while and I couldn't figure out the answer. I had added all the paths, built everything and pretty much followed what everyone on here had suggested, but no luck.
Finally I read the comments and saw that there were some compilation errors that were aborting the procedure before the binaries and exe file was generated.
Bottom line: Do a code review and make sure that there are no errors in your code because sometimes eclipse will not always catch everything.
If you can run a basic hello world but not your code then obviously something is wrong with your code. I learned the hard way.
Those are zero-length strings, not null. But if you want to remove them:
firstArray[0] refers to the first element
firstArray[1] refers to the second element
You can move the second into the first thusly:
firstArray[0] = firstArray[1]
If you were to do this for elements [1,2], then [2,3], etc. you would eventually shift the entire contents of the array to the left, eliminating element 0. Can you see how that would apply?

Add the class to the div you want to be scrollable.
overflow-x: hidden; hides the horizantal scrollbar. While overflow-y: scroll; allows you to scroll vertically.

fs.exist() is deprecated. So I have used fs.stat() to check the directory status. If the directory does not exist fs.stat() throw an error with message like 'no such file or directory'. Then I have created a directory.
const fs = require('fs').promises;
const dir = './dir';
fs.stat(dir).catch(async (err) => {
if (err.message.includes('no such file or directory')) {
await fs.mkdir(dir);
}

If you want the old directive back, you can add this to your app:
Directive:
directives.directive('ngBindHtmlUnsafe', ['$sce', function($sce){
return {
scope: {
ngBindHtmlUnsafe: '=',
},
template: "<div ng-bind-html='trustedHtml'></div>",
link: function($scope, iElm, iAttrs, controller) {
$scope.updateView = function() {
$scope.trustedHtml = $sce.trustAsHtml($scope.ngBindHtmlUnsafe);
}
$scope.$watch('ngBindHtmlUnsafe', function(newVal, oldVal) {
$scope.updateView(newVal);
});
}
};
}]);
Usage
<div ng-bind-html-unsafe="group.description"></div>
I had a similar issue when deploying from OSx on my local to my Linux live site.
It ran fine on OSx, but on Linux I was getting:
An Error Was Encountered
Unable to load the requested class: Ckeditor
The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".
I also changed my load call to match the capitalization:
$this->load->library('CKEditor');
If you are working with a one-dimensional array there is a syntactic sugar:
>>> x = numpy.array([1,0,2,0,3,0,4,5,6,7,8])
>>> numpy.flatnonzero(x == 0)
array([1, 3, 5])
To be honest I like the OP's first way of actually starting it with a NULL
value and then checking it with is.null
(primarily because it is very simply and easy to understand). It maybe depends on the way people are used to coding but the Hadley seems to support the is.null
way too:
From Hadley's book "Advanced-R" Chapter 6, Functions, p.84 (for the online version check here):
You can determine if an argument was supplied or not with the missing() function.
i <- function(a, b) {
c(missing(a), missing(b))
}
i()
#> [1] TRUE TRUE
i(a = 1)
#> [1] FALSE TRUE
i(b = 2)
#> [1] TRUE FALSE
i(1, 2)
#> [1] FALSE FALSE
Sometimes you want to add a non-trivial default value, which might take several lines of code to compute. Instead of inserting that code in the function definition, you could use missing() to conditionally compute it if needed. However, this makes it hard to know which arguments are required and which are optional without carefully reading the documentation. Instead, I usually set the default value to NULL and use is.null() to check if the argument was supplied.
For AWS users.
I had to use the following steps to get there.
1) Ensure that pip and django are installed at the sudo level
2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0
3) Add Public IP and DNS to ALLOWED_HOSTS
4) Launch development server with sudo on port 80
Site now available at either of the following (no need for :80 as that is default for http):
In addition to using Request.Form
and Request.QueryString
and depending on your specific scenario, it may also be useful to check the Page
's IsPostBack
property.
if (Page.IsPostBack)
{
// HTTP Post
}
else
{
// HTTP Get
}
You can use "transparent" as a colour. In some versions of IE, that comes up as black, but I've not tested it out since the IE6 days.

You need to have a doGet method as:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hola</title>");
out.println("</head>");
out.println("<body bgcolor=\"white\">");
out.println("</body>");
out.println("</html>");
}

If you have seaborn
installed, an easier method that does not require you to perform pivot
:
import seaborn as sns
sns.lineplot(data=df, x='x', y='y', hue='color')
The one above is ok...but you will encounter data corruption when you send stuff over SMTP (if you need to). I've altered to something else that will help to correctly send byte for byte: '
using System;
using System.IO;
private static byte[] ReadFully(string input)
{
FileStream sourceFile = new FileStream(input, FileMode.Open); //Open streamer
BinaryReader binReader = new BinaryReader(sourceFile);
byte[] output = new byte[sourceFile.Length]; //create byte array of size file
for (long i = 0; i < sourceFile.Length; i++)
output[i] = binReader.ReadByte(); //read until done
sourceFile.Close(); //dispose streamer
binReader.Close(); //dispose reader
return output;
}'
TRUE
and FALSE
are keywords, and should not be quoted as strings:
INSERT INTO first VALUES (NULL, 'G22', TRUE);
INSERT INTO first VALUES (NULL, 'G23', FALSE);
By quoting them as strings, MySQL will then cast them to their integer equivalent (since booleans are really just a one-byte INT
in MySQL), which translates into zero for any non-numeric string. Thus, you get 0
for both values in your table.
mysql> SELECT CAST('TRUE' AS SIGNED), CAST('FALSE' AS SIGNED), CAST('12345' AS SIGNED);
+------------------------+-------------------------+-------------------------+
| CAST('TRUE' AS SIGNED) | CAST('FALSE' AS SIGNED) | CAST('12345' AS SIGNED) |
+------------------------+-------------------------+-------------------------+
| 0 | 0 | 12345 |
+------------------------+-------------------------+-------------------------+
INT
representation:mysql> SELECT TRUE, FALSE;
+------+-------+

Note also, that I have replaced your double-quotes with single quotes as are more standard SQL string enclosures. Finally, I have replaced your empty strings for id
with NULL
. The empty string may issue a warning.
Here is a code sample I've used (with a .NET Core view):
@{
Microsoft.Extensions.Primitives.StringValues queryVal;
if (Context.Request.Query.TryGetValue("yourKey", out queryVal) &&
queryVal.FirstOrDefault() == "yourValue")
{
}
}
You can try doing:
if($("#form").validate()) {
return true;
} else {
return false;
}
Reference - Turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore,Microsoft recommend that you do not work around this problem by turning off the option.

There aren't trees built in, but you can easily construct one by subclassing a Node type from List and writing the traversal methods. If you do this, I've found bisect useful.
There are also many implementations on PyPi that you can browse.
If I remember correctly, the Python standard lib doesn't include tree data structures for the same reason that the .NET base class library doesn't: locality of memory is reduced, resulting in more cache misses. On modern processors it's usually faster to just bring a large chunk of memory into the cache, and "pointer rich" data structures negate the benefit.
somObject instanceof Date
should be
somObject instanceOf Date
You can use the list.sort
to avoid creating new lists with sorted
and sort the lists in place.
Also you should not use list
as a variable name as it shadows python's own list.
def median(l):
half = len(l) // 2
l.sort()
if not len(l) % 2:
return (l[half - 1] + l[half]) / 2.0
return l[half]

In Swift, the == operator is equivalent to Objective C's isEqual: method (it calls the isEqual method instead of just comparing pointers, and there's a new === method for testing that the pointers are the same), so you can just write this as:
if username == "" || password == ""
{
println("Sign in failed. Empty character")
}
From ScottGu's blog:
Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:
The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:
Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).
Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.
This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.
Also see this.
In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".
Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.
Wikipedia
There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.
Actually, be careful - they are not exactly the same.
If you define any interceptors within your application, they will not apply to Controllers annotated as @RestController
, however they do work with @Controller
annotated controllers.
ie. configuration for the interceptor:
@Configuration
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new TemplateMappingInterceptor()).addPathPatterns("/**", "/admin-functions**").excludePathPatterns("/login**");
}
}
and in the declaration of a Spring controller:
@Controller
public class AdminServiceController {...
Will work, however
@RestController
public class AdminServiceController {...
does not end up having the interceptor being associated with it.
Firstly, application.properties in the @PropertySource should read application-test.properties
if that's what the file is named (matching these things up matters):
@PropertySource("classpath:application-test.properties ")
That file should be under your /src/test/resources
classpath (at the root).
I don't understand why you'd specify a dependency hard coded to a file called application-test.properties
. Is that component only to be used in the test environment?
The normal thing to do is to have property files with the same name on different classpaths. You load one or the other depending on whether you are running your tests or not.
In a typically laid out application, you'd have:
src/test/resources/application.properties
and
src/main/resources/application.properties
And then inject it like this:
@PropertySource("classpath:application.properties")
The even better thing to do would be to expose that property file as a bean in your spring context and then inject that bean into any component that needs it. This way your code is not littered with references to application.properties and you can use anything you want as a source of properties. Here's an example: how to read properties file in spring project?
From performance point of view if two lists contain number of elements that differ significantly, you can try such approach (using conditional operator ?:):
1.First you need to declare a converter:
Converter<string, int> del = delegate(string s) { return Int32.Parse(s); };
2.Then you use a conditional operator:
var r = data1.Count > data2.Count ?
data2.ConvertAll<int>(del).Intersect(data1) :
data1.Select(v => v.ToString()).Intersect(data2).ToList<string>().ConvertAll<int>(del);
You convert elements of shorter list to match the type of longer list. Imagine an execution speed if your first set contains 1000 elements and second only 10 (or opposite as it doesn't matter) ;-)
As you want to have a result as List, in a last line you convert the result (only result) back to int.
The accepted answer (DROP SERIES) will work for many cases, but will not work if the records you need to delete are distributed among many time ranges and tag sets.
A more general purpose approach (albeit a slower one) is to issue the delete queries one-by-one, with the use of another programming language.
For each of the records you want to delete:
Format this into a query, e.g.
DELETE FROM "things" WHERE time=123123123 AND tag1='val' AND tag2='val'
Send each of the queries one at a time
This cannot be done with CMake. You have to generate two separate build folders. One for the x86 NMake build and one for the x64 NMake build. You cannot generate a single Visual Studio project covering both architectures with CMake, either.
To build Visual Studio projects from the command line for both 32-bit and 64-bit without starting a Visual Studio command prompt, use the regular Visual Studio generators.
For CMake 3.13 or newer, run the following commands:
cmake -G "Visual Studio 16 2019" -A Win32 -S \path_to_source\ -B "build32"
cmake -G "Visual Studio 16 2019" -A x64 -S \path_to_source\ -B "build64"
cmake --build build32 --config Release
cmake --build build64 --config Release
For earlier versions of CMake, run the following commands:
mkdir build32 & pushd build32
cmake -G "Visual Studio 15 2017" \path_to_source\
popd
mkdir build64 & pushd build64
cmake -G "Visual Studio 15 2017 Win64" \path_to_source\
popd
cmake --build build32 --config Release
cmake --build build64 --config Release
CMake generated projects that use one of the Visual Studio generators can be built from the command line with using the option --build
followed by the build directory. The --config
option specifies the build configuration.
I think currently your api's actually responding the way it should. The first 100 records on the page in the overall order of objects you are maintaining. Your explanation tells that you are using some kind of ordering ids to define the order of your objects for pagination.
Now, in case you want that page 2 should always start from 101 and end at 200, then you must make the number of entries on the page as variable, since they are subject to deletion.
You should do something like the below pseudocode:
page_max = 100
def get_page_results(page_no) :
start = (page_no - 1) * page_max + 1
end = page_no * page_max
return fetch_results_by_id_between(start, end)
I have almost exactly the same code as you and mine works.
Do you have jQueryUI.js included in the page?

You'll also need the ng-app="app" somewhere in your HTML
click windows-> preferences->Maven. uncheck "Offline" check box. This was not able to download archetype which I was using. When I uncheck it, Everything worked smooth.
After discussion posting updated answer:

Error Handling:
You could try something like this to catch a specific error:
On Error Resume Next
Set owb = Application.Workbooks.Open(fpath & "\" & fname)
If Err.Number = 1004 Then
GoTo FileNotFound
Else
End If
...
Exit Sub
FileNotFound: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then
Else: Call Clear
LIMIT limit OFFSET offset
will work.
But you need a stable ORDER BY
clause, or the values may be ordered differently for the next call (after any write on the table for instance).
SELECT *
FROM msgtable
WHERE cdate = '2012-07-18'
ORDER BY msgtable_id -- or whatever is stable
LIMIT 10
OFFSET 50; -- to skip to page 6
Use standard-conforming date style (ISO 8601 in my example), which works irregardless of your locale settings.
Paging will still shift if involved rows are inserted or deleted or changed in relevant columns. It has to.
To avoid that shift or for better performance with big tables use smarter paging strategies:
Create a File
object, passing the directory path to the constructor. Use the listFiles()
to retrieve an array of File
objects for each file in the directory, and then call the getName()
method to get the filename.
List<String> results = new ArrayList<String>();
File[] files = new File("/path/to/the/directory").listFiles();
//If this pathname does not denote a directory, then listFiles() returns null.
for (File file : files) {
if (file.isFile()) {
results.add(file.getName());
}
}
it works
first use: git reflog
find your SHA of your previus state and make (HEAD@{1} is an example)
git reset --hard HEAD@{1}
How about:
echo "hello" >> <filename>
Using the >>
operator will append data at the end of the file, while using the >
will overwrite the contents of the file if already existing.
You could also use printf
in the same way:
printf "hello" >> <filename>
Note that it can be dangerous to use the above. For instance if you already have a file and you need to append data to the end of the file and you forget to add the last >
all data in the file will be destroyed. You can change this behavior by setting the noclobber
variable in your .bashrc
:
set -o noclobber
Now when you try to do echo "hello" > file.txt
you will get a warning saying cannot overwrite existing file
.
To force writing to the file you must now use the special syntax:
echo "hello" >| <filename>
You should also know that by default echo
adds a trailing new-line character which can be suppressed by using the -n
flag:
echo -n "hello" >> <filename>

Go into your directory and click on 'Settings' next to the little cog. There is a field to rename your directory.
WebViewClient.shouldOverrideUrlLoading
might be helpful. We are having a similar requirement in one of our app. Not tried yet.
Your code is working just fine, you have to declare javscript method before DOM ready.
You're &
ing the wrong bits. I think you want:
s = *ptr >> 31;
e = *ptr & 0x7f800000;
e >>= 23;
m = *ptr & 0x007fffff;
Remember, when you &
, you are zeroing out bits that you don't set. So in this case, you want to zero out the sign bit when you get the exponent, and you want to zero out the sign bit and the exponent when you get the mantissa.
Note that the masks come directly from your picture. So, the exponent mask will look like:
0 11111111 00000000000000000000000
and the mantissa mask will look like:
0 00000000 11111111111111111111111
PowerShell has really wacky return semantics - at least when viewed from a more traditional programming perspective. There are two main ideas to wrap your head around:
Thus, the following two script blocks will do effectively the exact same thing:
$a = "Hello, World"
return $a
$a = "Hello, World"
$a
return
The $a variable in the second example is left as output on the pipeline and, as mentioned, all output is returned. In fact, in the second example you could omit the return entirely and you would get the same behavior (the return would be implied as the function naturally completes and exits).
Without more of your function definition I can't say why you are getting a PSMethod object. My guess is that you probably have something a few lines up that is not being captured and is being placed on the output pipeline.
It is also worth noting that you probably don't need those semicolons - unless you are nesting multiple expressions on a single line.
You can read more about the return semantics on the about_Return page on TechNet, or by invoking the help return
command from PowerShell itself.

You can make master
point at 1258f0d0aae
this way:
git checkout master
git reset --hard 1258f0d0aae
But you have to be careful about doing this. It may well rewrite the history of that branch. That would create problems if you have published it and other people are working on the branch.
Also, the git reset --hard
command will throw away any uncommitted changes (i.e. those just in your working tree or the index).
You can also force an update to a branch with:
git branch -f master 1258f0d0aae
... but git won't let you do that if you're on master
at the time.
Use android.database.DatabaseUtils to get number of count.
public long getTaskCount(long tasklist_Id) {
return DatabaseUtils.queryNumEntries(readableDatabase, TABLE_NAME);
}
It is easy utility that has multiple wrapper methods to achieve database operations.
To answer the title of your question directly because this comes up in Google first:
YES, TypeScript can export a function!
Here is a direct quote from the TS Documentation:
"Any declaration (such as a variable, function, class, type alias, or interface) can be exported by adding the export keyword."
If you looking for vertical LinearLayout Manager you can achieve smooth scrolling using a custom LinearSmoothScroller
:
import android.content.Context;
import android.graphics.PointF;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.LinearSmoothScroller;
import android.support.v7.widget.RecyclerView;
public class SnappingLinearLayoutManager extends LinearLayoutManager {
public SnappingLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super(context, orientation, reverseLayout);
}
@Override
public void smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state,
int position) {
RecyclerView.SmoothScroller smoothScroller = new TopSnappedSmoothScroller(recyclerView.getContext());
smoothScroller.setTargetPosition(position);
startSmoothScroll(smoothScroller);
}
private class TopSnappedSmoothScroller extends LinearSmoothScroller {
public TopSnappedSmoothScroller(Context context) {
super(context);
}
@Override
public PointF computeScrollVectorForPosition(int targetPosition) {
return SnappingLinearLayoutManager.this
.computeScrollVectorForPosition(targetPosition);
}
@Override
protected int getVerticalSnapPreference() {
return SNAP_TO_START;
}
}
}
use an instance of the layoutmanager in recycle view and then calling recyclerView.smoothScrollToPosition(pos);
will smooth scroll to selected position to top of the recycler view
After trying most of the solutions here, the easiest thing I found was the obvious - using a temp file. I'm not sure what you want to do with your multiple line output, but you can then deal with it line by line using read. About the only thing you can't really do is easily stick it all in the same variable, but for most practical purposes this is way easier to deal with.
./myscript.sh > /tmp/foo
while read line ; do
echo 'whatever you want to do with $line'
done < /tmp/foo
Quick hack to make it do the requested action:
result=""
./myscript.sh > /tmp/foo
while read line ; do
result="$result$line\n"
done < /tmp/foo
echo -e $result
Note this adds an extra line. If you work on it you can code around it, I'm just too lazy.
EDIT: While this case works perfectly well, people reading this should be aware that you can easily squash your stdin inside the while loop, thus giving you a script that will run one line, clear stdin, and exit. Like ssh will do that I think? I just saw it recently, other code examples here: https://unix.stackexchange.com/questions/24260/reading-lines-from-a-file-with-bash-for-vs-while
One more time! This time with a different filehandle (stdin, stdout, stderr are 0-2, so we can use &3 or higher in bash).
result=""
./test>/tmp/foo
while read line <&3; do
result="$result$line\n"
done 3</tmp/foo
echo -e $result
you can also use mktemp, but this is just a quick code example. Usage for mktemp looks like:
filenamevar=`mktemp /tmp/tempXXXXXX`
./test > $filenamevar
Then use $filenamevar like you would the actual name of a file. Probably doesn't need to be explained here but someone complained in the comments.
I use SQLYog at home and work. It turns out they DO have a free open-source version, though sadly they've been trying to hide that fact for the last few years.
You can download the open-source version from https://github.com/webyog/sqlyog-community - just click the "Download SQLyog Community Version" link.
For anyone looking for a full solution, I got this working with the following code based on maximdim's answer:
import javax.mail.*
import javax.mail.internet.*
private class SMTPAuthenticator extends Authenticator
{
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication('[email protected]', 'test1234');
}
}
def d_email = "[email protected]",
d_uname = "email",
d_password = "password",
d_host = "smtp.gmail.com",
d_port = "465", //465,587
m_to = "[email protected]",
m_subject = "Testing",
m_text = "Hey, this is the testing email."
def props = new Properties()
props.put("mail.smtp.user", d_email)
props.put("mail.smtp.host", d_host)
props.put("mail.smtp.port", d_port)
props.put("mail.smtp.starttls.enable","true")
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true")
props.put("mail.smtp.socketFactory.port", d_port)
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
props.put("mail.smtp.socketFactory.fallback", "false")
def auth = new SMTPAuthenticator()
def session = Session.getInstance(props, auth)
session.setDebug(true);
def msg = new MimeMessage(session)
msg.setText(m_text)
msg.setSubject(m_subject)
msg.setFrom(new InternetAddress(d_email))
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to))
Transport transport = session.getTransport("smtps");
transport.connect(d_host, 465, d_uname, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
