An API is ready-made source code library.

In Java for example APIs are a set of related classes and interfaces that come in packages. This picture illustrates the libraries included in the Java Standard Edition API. Packages are denoted by their color.

Just right click on the ConstrainLayout and select the "convert view" and then "RelativeLayout":

Also, the apt-show-versions package (installed separately) parses dpkg information about what is installed and tells you if packages are up to date.

I know I am kicking a dead post, but wanted to share this for completion sake:

A correct version of singleton generation template, that overcomes the flawed double-checked locking design (discussed above and mentioned else where)

Singleton Creation Template: Name this createsingleton

static enum Singleton {
    INSTANCE;

    private static final ${enclosing_type} singleton = new ${enclosing_type}();

    public ${enclosing_type} getSingleton() {
        return singleton;
    }
}
${cursor}

To access singletons generated using above:

Singleton reference Template: Name this getsingleton:

${type} ${newName} = ${type}.Singleton.INSTANCE.getSingleton();

The right choice really depends on how big the input string is and what the perforce and memory requirement are, but I would use a regular expression like

string result = Regex.Replace(s, @"\r\n?|\n|\t", String.Empty);

Or if we need to apply the same replacement multiple times, it is better to use a compiled version for the Regex like

var regex = new Regex(@"\r\n?|\n|\t", RegexOptions.Compiled); 
string result = regex.Replace(s, String.Empty);

NOTE: different scenarios requite different approaches to achieve the best performance and the minimum memory consumption

Slight improvement on @arun-p-johny answer:

In html,

<pre id="log"></pre>

In js,

(function () {
    var old = console.log;
    var logger = document.getElementById('log');
    console.log = function () {
      for (var i = 0; i < arguments.length; i++) {
        if (typeof arguments[i] == 'object') {
            logger.innerHTML += (JSON && JSON.stringify ? JSON.stringify(arguments[i], undefined, 2) : arguments[i]) + '<br />';
        } else {
            logger.innerHTML += arguments[i] + '<br />';
        }
      }
    }
})();

Start using:

console.log('How', true, new Date());

FailedPreconditionError: Attempting to use uninitialized value is one of the most frequent errors related to tensorflow. From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

Because of things like this, as a general rule of thumb, I try to avoid as much XAML "trickery" as possible and keep the XAML as dumb and simple as possible and do the rest in the ViewModel (or attached properties or IValueConverters etc. if really necessary).

If possible I would give the ViewModel of the current DataContext a reference (i.e. property) to the relevant parent ViewModel

public class ThisViewModel : ViewModelBase
{
    TypeOfAncestorViewModel Parent { get; set; }
}

and bind against that directly instead.

<TextBox Text="{Binding Parent}" />

It is never a good idea to break out of a for-loop. If you are using a for-loop it means that you know how many times you want to iterate. Use a while-loop with 2 conditions.

for example

var done = false
while (i <= length && !done) {
  if (sum > 1000) {
     done = true
  }
}

Element.scrollHeight is a property, not a function, as noted here. As noted here, the scrollHeight property is only supported after IE8. If you need it to work before that, temporarily set the CSS overflow and height to auto, which will cause the div to take the maximum height it needs. Then get the height, and change the properties back to what they were before.

From: http://nginx.org/r/large_client_header_buffers

Syntax: large_client_header_buffers number size ;
Default: large_client_header_buffers 4 8k;
Context: http, server

Sets the maximum number and size of buffers used for reading large client request header. A request line cannot exceed the size of one buffer, or the 414 (Request-URI Too Large) error is returned to the client. A request header field cannot exceed the size of one buffer as well, or the 400 (Bad Request) error is returned to the client. Buffers are allocated only on demand. By default, the buffer size is equal to 8K bytes. If after the end of request processing a connection is transitioned into the keep-alive state, these buffers are released.

so you need to change the size parameter at the end of that line to something bigger for your needs.

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

For those interested, here's an alternative to invoking Array.join:

var arrayOfStrings = ['foo', 'bar'];
var result = String.concat.apply(null, arrayOfStrings);
console.log(result);

The output, as expected, is the string 'foobar'. In Firefox, this approach outperforms Array.join but is outperformed by + concatenation. Since String.concat requires each segment to be specified as a separate argument, the caller is limited by any argument count limit imposed by the executing JavaScript engine. Take a look at the documentation of Function.prototype.apply() for more information.

If you want to stringify an HTML element in order to pass it somewhere and parse it back to an element try by creating a unique query for the element:

// 'e' is a circular object that can't be stringify
var e = document.getElementById('MyElement')

// now 'e_str' is a unique query for this element that can be stringify 
var e_str = e.tagName
  + ( e.id != "" ? "#" + e.id : "")
  + ( e.className != "" ? "." + e.className.replace(' ','.') : "");

//now you can stringify your element to JSON string
var e_json = JSON.stringify({
  'element': e_str
})

than

//parse it back to an object
var obj = JSON.parse( e_json )

//finally connect the 'obj.element' varible to it's element
obj.element = document.querySelector( obj.element )

//now the 'obj.element' is the actual element and you can click it for example:
obj.element.click();

You could do it without javascript and simply use anchor tags? Then it would be accessible to those js free.

although as you are using modals, I assume you don't care about being js free. ;)

Try one of these solutions

1. In vscode settings.json file add this entry "prettier.singleQuote": true
2. In vscode if you have .editorconfig file, add this line under the root [*] symbol quote_type = single
3. In vscode if you have .prettierrc file, add this line

{
    "singleQuote": true,
    "vetur.format.defaultFormatterOptions": {
        "prettier": {
            "singleQuote": true
        }
    }
}

If str is null, undefined or 0, this code will set it to "hai"

function(nodeBox, str) {
  str = str || "hai";
.
.
.

If you also need to pass 0, you can use:

function(nodeBox, str) {
  if (typeof str === "undefined" || str === null) { 
    str = "hai"; 
  }
.
.
.

Background

MD2 was widely recognized as insecure and thus disabled in Java in version JDK 6u17 (see release notes http://www.oracle.com/technetwork/java/javase/6u17-141447.html, "Disable MD2 in certificate chain validation"), as well as JDK 7, as per the configuration you pointed out in java.security.

Verisign was using a Class 3 root certificate with the md2WithRSAEncryption signature algorithm (serial 70:ba:e4:1d:10:d9:29:34:b6:38:ca:7b:03:cc:ba:bf), but deprecated it and replaced it with another certificate with the same key and name, but signed with algorithm sha1WithRSAEncryption. However, some servers are still sending the old MD2 signed certificate during the SSL handshake (ironically, I ran into this problem with a server run by Verisign!).

You can verify that this is the case by getting the certificate chain from the server and examining it:

openssl s_client -showcerts -connect <server>:<port>

Recent versions of the JDK (e.g. 6u21 and all released versions of 7) should resolve this issue by automatically removing certs with the same issuer and public key as a trusted anchor (in cacerts by default).

If you still have this issue with newer JDKs

Check if you have a custom trust manager implementing the older X509TrustManager interface. JDK 7+ is supposed to be compatible with this interface, however based on my investigation when the trust manager implements X509TrustManager rather than the newer X509ExtendedTrustManager (docs), the JDK uses its own wrapper (AbstractTrustManagerWrapper) and somehow bypasses the internal fix for this issue.

The solution is to:

1. use the default trust manager, or

2. modify your custom trust manager to extend X509ExtendedTrustManager directly (a simple change).

I don't think it's possible.

You can use mysqldump to dump the data and then create a schema with your new name and then dump the data into that new database.

       //get the main handle and remove it
       //whatever remains is the child pop up window handle

       String mainHandle = driver.getWindowHandle();
       Set<String> allHandles = driver.getWindowHandles();
       Iterator<String> iter = allHandles.iterator();
       allHandles.remove(mainHandle);
       String childHandle=iter.next();

@John Woo's accepted answer has some caveats which you should be aware of:

1. Default language setting of a session is controlled from default language setting of the user login instead which you have used to create the session. SQL Server instance level setting doesn't affect the default language of the session.
2. Changing default language setting at SQL Server instance level doesn't affects the default language setting of the existing SQL Server logins. It is meant to be inherited only by the new user logins that you create after changing the instance level setting.

So, there is an intermediate level between your SQL Server instance and the session which you can use to control the default language setting for session - login level.

SQL Server Instance level setting -> User login level setting -> Query Session level setting

This can help you in case you want to set default language of all new sessions belonging to some specific user only.

Simply change the default language setting of the target user login as per this link and you are all set. You can also do it from SQL Server Management Studio (SSMS) UI. Below you can see the default language setting in properties window of sa user in SQL Server:

Note: Also, it is important to know that changing the setting doesn't affect the default language of already active sessions from that user login. It will affect only the new sessions created after changing the setting.

Your current location might not be available immediately, after the map fragment is initialized.

After set

googleMap.setMyLocationEnabled(true);

you have to wait until you see the blue dot shown on your MapView. Then

Location myLocation = googleMap.getMyLocation();

myLocation won't be null.

I think you better use the LocationClient instead, and implement your own LocationListener.onLocationChanged(Location l)

Receiving Location Updates will show you how to get current location from LocationClient

I have same problem after upgrading to Gradle Wrapper 5.1.rec3. I am back to Gradle 4.6

in my case this worked perfectly

Microsoft Virtual WiFi Miniport should start and bind automatically to the underlying function driver. Try disabling and reenabling the AR9285 driver.

From Python you can do directly using below code

import subprocess
proc = subprocess.check_output('C:\Windows\System32\cmd.exe /k %windir%\System32\\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f' ,stderr=subprocess.STDOUT,shell=True)
    print(str(proc))

in first parameter just executed User Account setting you may customize with yours.

You can have option of:

1. multi_curl
2. One can use system command for the same
3. Ideal scenario is, create a threading function in C language and compile/configure in PHP. Now that function will be the function of PHP.

This worked

<button onclick="window.location.href=window.location.href; return false;">Continue</button>

The reason it doesn't work without the return false; is that the button click would trigger a form submit. With an explicit return false on it, it doesn't do the form submit and just does the reload of the same page that was a result of a previous POST to that page.

It failed because there is no server install on your computer. You need to Download 'MySQL Community Server 8.0.17' & restart your server.

As this helpful article states: On OS X to start/stop MySQL from the command line:

sudo /usr/local/mysql/support-files/mysql.server start 
sudo /usr/local/mysql/support-files/mysql.server stop 

On Linux start/stop from the command line:

/etc/init.d/mysqld start 
/etc/init.d/mysqld stop 
/etc/init.d/mysqld restart 

Some Linux flavours offer the service command too

# service mysqld start 
# service mysqld stop 
# service mysqld restart

or

 # service mysql start 
 # service mysql stop 
 # service mysql restart 

Import mplot3d whole to use "projection = '3d'".

Insert the command below in top of your script. It should run fine.

from mpl_toolkits import mplot3d

Your for loop doesn't need to just add one. You can loop by three.

for(int i = 0; i < theData.Length; i+=3)
{
  string value1 = theData[i];
  string value2 = theData[i+1];
  string value3 = theData[i+2];
}

Basically, you are just using indexes to grab the values in your array. One point to note here, I am not checking to see if you go past the end of your array. Make sure you are doing bounds checking!

If you wrap your <li> content in a <span> or other tag, you may change the font size of the <li>, which will change the size of the bullet, then reset the content of the <li> to its original size. You may use em units to resize the <li> bullet proportionally.

For example:

<ul>
    <li><span>First item</span></li>
    <li><span>Second item</span></li>
</ul>

Then CSS:

li {
    list-style-type: disc;
    font-size: 0.8em;
}

li * {
    font-size: initial;
}

A more complex example:

<!DOCTYPE html>
<html lang="en">
<head>
    <title>List Item Bullet Size</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <style>
ul.disc li {
    list-style-type: disc;
    font-size: 1.5em;
}

ul.square li {
    list-style-type: square;
    font-size: 0.8em;
}

li * {
    font-size: initial;
}
    </style>
</head>
<body>

<h1>First</h1>
<ul class="disc">
    <li><span>First item</span></li>
    <li><span>Second item</span></li>
</ul>

<h1>Second</h1>
<ul class="square">
    <li><span>First item</span></li>
    <li><span>Second item</span></li>
</ul>

</body>
</html>

Results in:

If this helps anybody, I encountered this while using purr::map() with a function I wrote which was something like this:

find_nearby_shops <- function(base_account) {
   states_table %>% 
        filter(state == base_account$state) %>% 
        left_join(target_locations, by = c('border_states' = 'state')) %>% 
        mutate(x_latitude = base_account$latitude,
               x_longitude = base_account$longitude) %>% 
        mutate(dist_miles = geosphere::distHaversine(p1 = cbind(longitude, latitude), 
                                                     p2 = cbind(x_longitude, x_latitude))/1609.344)
}

nearby_shop_numbers <- base_locations %>% 
    split(f = base_locations$id) %>% 
    purrr::map_df(find_nearby_shops) 

I would get this error sometimes with samples, but most times I wouldn't. The root of the problem is that some of the states in the base_locations table (PR) did not exist in the states_table, so essentially I had filtered out everything, and passed an empty table on to mutate. The moral of the story is that you may have a data issue and not (just) a code problem (so you may need to clean your data.)

Thanks for agstudy and zx8754's answers above for helping with the debug.

If you want to check for local files first do:

@font-face {
font-family: 'Green Sans Web';
src:

}

There is a more elaborate description of what to do here.

I like the solution of Hans-Peter Störr... But I think it is not quite correct. Sadly containsInAnyOrder does not accept a Collection of objetcs to compare to. So it has to be a Collection of Matchers:

assertThat(set1, containsInAnyOrder(set2.stream().map(IsEqual::equalTo).collect(toList())))

The import are:

import static java.util.stream.Collectors.toList;
import static org.hamcrest.Matchers.containsInAnyOrder;
import static org.junit.Assert.assertThat;

I think the exact answer is: for api 11 or higher:

getActionBar().setDisplayShowHomeEnabled(false);

otherwise:

getSupportActionBar().setDisplayShowHomeEnabled(false);

(because it need a support library.)

The ISO C99 standard specifies that these macros must only be defined if explicitly requested.

#define __STDC_FORMAT_MACROS
#include <inttypes.h>

You can find out what Git does with a file by seeing what it does when you add it to the index. The index is like a pre-commit. With the index committed, you can use git checkout to bring everything that was in the index back into the working directory. So, what does Git do when you add a symbolic link to the index?

To find out, first, make a symbolic link:

$ ln -s /path/referenced/by/symlink symlink

Git doesn't know about this file yet. git ls-files lets you inspect your index (-s prints stat-like output):

$ git ls-files -s ./symlink
[nothing]

Now, add the contents of the symbolic link to the Git object store by adding it to the index. When you add a file to the index, Git stores its contents in the Git object store.

$ git add ./symlink

So, what was added?

$ git ls-files -s ./symlink
120000 1596f9db1b9610f238b78dd168ae33faa2dec15c 0       symlink

The hash is a reference to the packed object that was created in the Git object store. You can examine this object if you look in .git/objects/15/96f9db1b9610f238b78dd168ae33faa2dec15c in the root of your repository. This is the file that Git stores in the repository, that you can later check out. If you examine this file, you'll see it is very small. It does not store the contents of the linked file. To confirm this, print the contents of the packed repository object with git cat-file:

$ git cat-file -p 1596f9db1b9610f238b78dd168ae33faa2dec15c
/path/referenced/by/symlink

(Note 120000 is the mode listed in ls-files output. It would be something like 100644 for a regular file.)

But what does Git do with this object when you check it out from the repository and into your filesystem? It depends on the core.symlinks config. From man git-config:

core.symlinks

If false, symbolic links are checked out as small plain files that contain the link text.

So, with a symbolic link in the repository, upon checkout you either get a text file with a reference to a full filesystem path, or a proper symbolic link, depending on the value of the core.symlinks config.

Either way, the data referenced by the symlink is not stored in the repository.

Go to File > Project Structure > Select Module > Properties

After that CLICK on your project which will shown in LEFT PANEL

Then Select Properties Change Build Tool Version to 22.0.1

It works for sure

If animating opacity is not an option, you can also animate background-size.

For example, I used this CSS to set a backgound-image with a delay.

.before {
  background-size: 0;
}

.after {
  transition: background 0.1s step-end;
  background-image: $path-to-image;
  background-size: 20px 20px;
}

In Python 3.

GPA = 2.5
print(" %6.1f " % GPA)

6.1f means after the dots 1 digits show if you print 2 digits after the dots you should only %6.2f such that %6.3f 3 digits print after the point.

You can update with a join if you only affect one table like this:

UPDATE table1 
SET table1.name = table2.name 
FROM table1, table2 
WHERE table1.id = table2.id 
AND table2.foobar ='stuff'

But you are trying to affect multiple tables with an update statement that joins on multiple tables. That is not possible.

However, updating two tables in one statement is actually possible but will need to create a View using a UNION that contains both the tables you want to update. You can then update the View which will then update the underlying tables.

SQL JOINS

But this is a really hacky parlor trick, use the transaction and multiple updates, it's much more intuitive.

Simply get date and convert

Declare @Date as Date =Getdate()

Select Format(@Date,'dd/MM/yyyy') as [dd/MM/yyyy] // output: 22/10/2020
Select Format(@Date,'dd-MM-yyyy') as [dd-MM-yyyy] // output: 22-10-2020

//string date
Select Format(cast('25/jun/2013' as date),'dd/MM/yyyy') as StringtoDate // output: 25/06/2013

Source: SQL server date format and converting it (Various examples)

To diagnose this error quickly drop to a terminal or use the terminal built into Android Studio (accessible on in bottom status bar). Change to the main directory for your PROJECT (where settings.gradle is located).

1.) Check to make sure your settings.gradle includes the subproject. Something like this. This ensures your multi-project build knows about your library sub-project.

include ':apps:App1', ':apps:App2', ':library:Lib1'

Where the text between the colons are sub-directories.

2.) Run the following gradle command just see if Gradle can give you a list of tasks for the library. Use the same qualifier in the settings.gradle definition. This will uncover issues with the Library build script in isolation.

./gradlew :library:Lib1:tasks --info

3.) Make sure the output from the last step listed an "assembleDefault" task. If it didn't make sure the Library is including the Android Library plugin in build.gradle. Like this at the very top.

apply plugin: 'com.android.library'

I know the original poster's question was answered but I believe the answer has evolved over the past year and I think there are multiple reasons for the error. I think this resolution flow should assist those who run into the various issues.

I've placed this answer because Erwin Smout posted a answer that was so wrong it highlighted that there is probably a need to specifically guard against it.

Erwin suggested:

"Why should every SELECT always include DISTINCT ?"

A more appropriate question would be: If someone were to make the claim that: "every SELECT always include DISTINCT"; how would you comment on the claim?

If a candidate is unable to shoot the claim down in flames they either:

• Don't understand the problem with the claim.
• Lack in critical thinking skills.
• Lack in ability to communicate technical issues.

For the record

1. Suppose your query is correct, and does not return any duplicates, then including DISTINCT simply forces the RDBMS to check your result (zero benefit, and a lot of additional processing).
2. Suppose your query is incorrect, and does return duplicates, then including DISTINCT simply hides the problem (again with additional processing). It would be better to spot the problem and fix your query... it'll run faster that way.

Inset of getBitmap which is depricated now I use the following approach in Kotlin

PICK_IMAGE_REQUEST ->
    data?.data?.let {
        val bitmap = BitmapFactory.decodeStream(contentResolver.openInputStream(it))
        imageView.setImageBitmap(bitmap)
    }

The <figcaption> tag in HTML5 allows you to enter text to your image for example:

<figcaption>
Your text here
</figcaption>.

You can then use CSS to position the text where it should be on the image.

For modern JS, use event.key!

document.addEventListener("keypress", function onPress(event) {
    if (event.key === "z" && event.ctrlKey) {
        // Do something awesome
    }
});

NOTE: The old properties (.keyCode and .which) are Deprecated.

*IntelliJ 13 * (its paid for) We found you have to have the cursor in the actual class before ctrl+Shift+T worked.

Which seems a bit restrictive if its the only way to generate a test class. Although in retrospect it would force developers to create a test class when they write a functional class.

This functionality is now supported by Python 3.8+ :)

There's lightweight binary editor, check hexedit. http://www.linux.org/apps/AppId_6968.html. I tried using it for editing ELF binaries in Linux at least.

You can use hasOwnProperty() as well as in operator.

Use event delegation for dynamically created elements:

$(document).on("click", '.mylink', function(event) { 
    alert("new link clicked!");
});

This does actually work, here's an example where I appended an anchor with the class .mylink instead of data - http://jsfiddle.net/EFjzG/

I think you can initialize the variables a value like -1, because if the int type variables is not initialized it can't be used. When you want to check if it is not the value you want you can check if it is -1.

This is a security update. If an attacker can modify some file in the web server (the JS one, for example), he can make every loaded pages to download another script (for example to keylog your password or steal your SessionID and send it to his own server).

To avoid it, the browser check the Same-origin policy

Your problem is that the browser is trying to load something with your script (with an Ajax request) that is on another domain (or subdomain). To avoid it (if it is on your own website) you can:

• Copy the element on your own server (but it will be static).
• You can change your HTTP header to accept Cross-Origin content. See the Access-Control-Allow-Origin documentation for more information.

Agile and Scrum are terms used in project management. The Agile methodology employs incremental and iterative work beats that are also called sprints. Scrum, on the other hand is the type of agile approach that is used in software development.

Agile is the practice and Scrum is the process to following this practice same as eXtreme Programming (XP) and Kanban are the alternative process to following Agile development practice.

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

iisexpress program is responsible for that.

You can use Linq to XML to do this:

XDocument doc = XDocument.Load("input.xml");
var q = from node in doc.Descendants("Setting")
        let attr = node.Attribute("name")
        where attr != null && attr.Value == "File1"
        select node;
q.ToList().ForEach(x => x.Remove());
doc.Save("output.xml");

Just to keep this up to date:

The current version of SQLDeveloper has an export tool (Tools > Database Export) that will allow you to dump a schema to a file, with filters for object types, object names, table data etc.

It's a fair amount easier to set-up and use than exp and imp if you're used to working in a GUI environment, but not as versatile if you need to use it for scripting anything.

Use:

1..10 | % { write "loop $_" }

Output:

PS D:\temp> 1..10 | % { write "loop $_" }
loop 1
loop 2
loop 3
loop 4
loop 5
loop 6
loop 7
loop 8
loop 9

If you are using Ruby on Rails there is a squish

> @title = " abc "
 => " abc " 

> @title.squish
 => "abc"
> @title
 => " abc "

> @title.squish!
 => "abc"
> @title
 => "abc" 

If you are using just Ruby you want to use strip

Herein lies the gotcha.. in your case you want to use strip without the bang !

while strip! certainly does return nil if there was no action it still updates the variable so strip! cannot be used inline. If you want to use strip inline you can use the version without the bang !

strip! using multi line approach

> tokens["Title"] = " abc "
 => " abc "
> tokens["Title"].strip!
 => "abc"
> @title = tokens["Title"]
 => "abc"

strip single line approach... YOUR ANSWER

> tokens["Title"] = " abc "
 => " abc "
> @title = tokens["Title"].strip if tokens["Title"].present?
 => "abc"

You are using encode("utf-8") incorrectly. Python byte strings (str type) have an encoding, Unicode does not. You can convert a Unicode string to a Python byte string using uni.encode(encoding), and you can convert a byte string to a Unicode string using s.decode(encoding) (or equivalently, unicode(s, encoding)).

If fullFilePath and path are currently a str type, you should figure out how they are encoded. For example, if the current encoding is utf-8, you would use:

path = path.decode('utf-8')
fullFilePath = fullFilePath.decode('utf-8')

If this doesn't fix it, the actual issue may be that you are not using a Unicode string in your execute() call, try changing it to the following:

cur.execute(u"update docs set path = :fullFilePath where path = :path", locals())

Unfortunately GIT commands like prune and reset or push didn't work for me. Prune worked once and then the issue returned.

The permanent solution which worked for me is to edit a git file manually. Just go to the project's .git folder and then open the file packed-refs in a text editor like Notepad++. Then navigate to the row with the failing branch and update its guid to the expected one.

If you have a message like:

error: cannot lock ref 'refs/remotes/origin/feature/branch_xxx': is at 425ea23facf96f51f412441f41ad488fc098cf23 but expected 383de86fed394ff1a1aeefc4a522d886adcecd79

then in the file find the row with refs/remotes/origin/feature/branch_xxx. The guid there will be the expected (2nd) one - 383de86fed394ff1a1aeefc4a522d886adcecd79. You need to change it to the real (1st) one - 425ea23facf96f51f412441f41ad488fc098cf23.

Repeat for the other failing branches and you'll be good to proceed. Sometimes after re-fetch I had to repeat for the same branches which i already 'fixed' earlier. On re-fetch GIT updates guids and gives you the latest one.

Anyways the issue isn't a show stopper. The branch list gets updated. This is rather a warning.

I faced the same issues. To solve this, I used export PYTHONPATH="$PWD". However, in this case, you will need to modify imports in your Scripts dir depending on the below:

Case 1: If you are in the user_management dir, your scripts should use this style from Modules import LDAPManager to import module.

Case 2: If you are out of the user_management 1 level like main, your scripts should use this style from user_management.Modules import LDAPManager to import modules.

I Have a Query With This result :

SELECT Top 3
 id,
 Paytype
 FROM dbo.OrderExpresses
 WHERE CreateDate > '2018-04-08'

The Result is :

22082   1
22083   2
22084   1

I Want Change The Code To String In Query, So I Use This Code :

SELECT TOP 3

 CASE WHEN Paytype = 1 THEN N'Credit' ELSE N'Cash' END AS PayTypeString
 FROM dbo.OrderExpresses
 WHERE CreateDate > '2018-04-08'

And Result Is :)

Just to add to this as I have had problems with an install of eclipse on my machine.

Specs: Win 7 x64 on macbook pro. The broken eclipse was galileo, and 1 of 4 installations on my machine at the time - the others were all working.

I was not running proxy, so above solution in the question did not work.

I found an answer that said to get updates for eclipse, and that would fix things. I tried this, and eclipse said there were no updates, but then for some reason I can't understand, my plugins could now install.

... more anecdotal evidence of a problem, and a possible solution, however strange ...

Just create the header.php file, and where you want to use it do:

<?php
include('header.php');
?>

Same with the footer. You don't need php tags in these files if you just have html.

See more about include here:

http://php.net/manual/en/function.include.php

With a simple JSON object, you don't need jQuery:

for (var i in json) {
   for (var j in json[i]) {
     console.log(json[i][j]);
   }
}

Use a custom comparator:

Collections.sort(nodeList, new Comparator<DataNode>(){
     public int compare(DataNode o1, DataNode o2){
         if(o1.degree == o2.degree)
             return 0;
         return o1.degree < o2.degree ? -1 : 1;
     }
});

Is there a name to describe this idiom?

In UML it is called aggregation. It differs from composition in that the member object is not owned by the referring class. In C++ you can implement aggregation in two different ways, through references or pointers.

I am assuming it is to prevent the possibly large overhead of copying a big complex object?

No, that would be a really bad reason to use this. The main reason for aggregation is that the contained object is not owned by the containing object and thus their lifetimes are not bound. In particular the referenced object lifetime must outlive the referring one. It might have been created much earlier and might live beyond the end of the lifetime of the container. Besides that, the state of the referenced object is not controlled by the class, but can change externally. If the reference is not const, then the class can change the state of an object that lives outside of it.

Is this generally good practice? Are there any pitfalls to this approach?

It is a design tool. In some cases it will be a good idea, in some it won't. The most common pitfall is that the lifetime of the object holding the reference must never exceed the lifetime of the referenced object. If the enclosing object uses the reference after the referenced object was destroyed, you will have undefined behavior. In general it is better to prefer composition to aggregation, but if you need it, it is as good a tool as any other.

Call like this

my_function ("", options);

It's one end of a communication channel, so often this would be represented as the URL of a server or service.

99.9% likely that you have corrupted memory (over- or under-flowed a buffer, wrote to a pointer after it was freed, called free twice on the same pointer, etc.)

Run your code under Valgrind to see where your program did something incorrect.

Java says that the default length of a JAVA array at the time of initialization will be 10.

private static final int DEFAULT_CAPACITY = 10;

But the size() method returns the number of inserted elements in the array, and since at the time of initialization, if you have not inserted any element in the array, it will return zero.

private int size;

public boolean add(E e) {
    ensureCapacityInternal(size + 1);  // Increments modCount!!
    elementData[size++] = e;
    return true;
}

public void add(int index, E element) {
    rangeCheckForAdd(index);
    ensureCapacityInternal(size + 1);  // Increments modCount!!
    System.arraycopy(elementData, index, elementData, index + 1,size - index);
    elementData[index] = element;
    size++;
}

Use Thread.sleep(1000);

1000 is the number of milliseconds that the program will pause.

try
{
    Thread.sleep(1000);
}
catch(InterruptedException ex)
{
    Thread.currentThread().interrupt();
}

Starting from Python 3.7, strptime supports colon delimiters in UTC offsets (source). So you can then use:

import datetime
datetime.datetime.strptime('2018-01-31T09:24:31.488670+00:00', '%Y-%m-%dT%H:%M:%S.%f%z')

EDIT:

As pointed out by Martijn, if you created the datetime object using isoformat(), you can simply use datetime.fromisoformat()

Here's a simple and working method I found elsewhere:

string hexString = "7FF";
int hexNumber;
sscanf(hexString.c_str(), "%x", &hexNumber);

Please note that you might prefer using unsigned long integer/long integer, to receive the value. Another note, the c_str() function just converts the std::string to const char* .

So if you have a const char* ready, just go ahead with using that variable name directly, as shown below [I am also showing the usage of the unsigned long variable for a larger hex number. Do not confuse it with the case of having const char* instead of string]:

const char *hexString = "7FFEA5"; //Just to show the conversion of a bigger hex number
unsigned long hexNumber; //In case your hex number is going to be sufficiently big.
sscanf(hexString, "%x", &hexNumber);

This works just perfectly fine (provided you use appropriate data types per your need).

Use np.ravel (for a 1D view) or np.ndarray.flatten (for a 1D copy) or np.ndarray.flat (for an 1D iterator):

In [12]: a = np.array([[1,2,3], [4,5,6]])

In [13]: b = a.ravel()

In [14]: b
Out[14]: array([1, 2, 3, 4, 5, 6])

Note that ravel() returns a view of a when possible. So modifying b also modifies a. ravel() returns a view when the 1D elements are contiguous in memory, but would return a copy if, for example, a were made from slicing another array using a non-unit step size (e.g. a = x[::2]).

If you want a copy rather than a view, use

In [15]: c = a.flatten()

If you just want an iterator, use np.ndarray.flat:

In [20]: d = a.flat

In [21]: d
Out[21]: <numpy.flatiter object at 0x8ec2068>

In [22]: list(d)
Out[22]: [1, 2, 3, 4, 5, 6]

You need to add a CDATA tag inside of the script tag, unless you want to manually go through and escape all XHTML characters (e.g. & would need to become &). For example:

<script>
//<![CDATA[
var el = document.getElementById("pacman");

if (Modernizr.canvas && Modernizr.localstorage && 
    Modernizr.audio && (Modernizr.audio.ogg || Modernizr.audio.mp3)) {
  window.setTimeout(function () { PACMAN.init(el, "./"); }, 0);
} else { 
  el.innerHTML = "Sorry, needs a decent browser<br /><small>" + 
    "(firefox 3.6+, Chrome 4+, Opera 10+ and Safari 4+)</small>";
}
//]]>
</script>

You can also use git-fat. I like that it only depends on stock Python and rsync. It also supports the usual Git workflow, with the following self explanatory commands:

git fat init
git fat push
git fat pull

In addition, you need to check in a .gitfat file into your repository and modify your .gitattributes to specify the file extensions you want git fat to manage.

You add a binary using the normal git add, which in turn invokes git fat based on your gitattributes rules.

Finally, it has the advantage that the location where your binaries are actually stored can be shared across repositories and users and supports anything rsync does.

UPDATE: Do not use git-fat if you're using a Git-SVN bridge. It will end up removing the binary files from your Subversion repository. However, if you're using a pure Git repository, it works beautifully.

The earlier version of this answer (a "hack" for rextester.com) is mostly redundant now that http://gcc.godbolt.org/ provides CL 19 RC for ARM, x86, and x86-64 (targeting the Windows calling convention, unlike gcc, clang, and icc on that site).

The Godbolt compiler explorer is designed for nicely formatting compiler asm output, removing the "noise" of directives, so I'd highly recommend using it to look at asm for simple functions that take args and return a value (so they won't be optimized away).

For a while, CL was available on http://gcc.beta.godbolt.org/ but not the main site, but now it's on both.

To get MSVC asm output from the http://rextester.com/l/cpp_online_compiler_visual online compiler: Add /FAs to the command line options. Have your program find its own path and work out the path to the .asm and dump it. Or run a disassembler on the .exe.

e.g. http://rextester.com/OKI40941

#include <string>
#include <boost/filesystem.hpp>
#include <Windows.h>

using namespace std;

static string my_exe(void){
    char buf[MAX_PATH];
    DWORD tmp = GetModuleFileNameA( NULL, // self
                                  buf, MAX_PATH);
    return buf;
}

int main() {
    string dircmd = "dir ";
    boost::filesystem::path p( my_exe() );
    //boost::filesystem::path dir = p.parent_path();

    // transform c:\foo\bar\1234\a.exe 
    // into      c:\foo\bar\1234\1234.asm
    p.remove_filename();
    system ( (dircmd + p.string()).c_str() );

    auto subdir = p.end();      // pointing at one-past the end
    subdir--;                   // pointing at the last directory name
    p /= *subdir;               // append the last dir name as a filename
    p.replace_extension(".asm");
    system ( (string("type ") + p.string()).c_str() );
//    std::cout << "Hello, world!\n";
}

... code of functions you want to see the asm for goes here ...

type is the DOS version of cat. I didn't want to include more code that would make it harder to find the functions I wanted to see the asm for. (Although using std::string and boost run counter to those goals! Some C-style string manipulation that makes more assumptions about the string it's processing (and ignores max-length safety / allocation by using a big buffer) on the result of GetModuleFileNameA would be much less total machine code.)

IDK why, but cout << p.string() << endl only shows the basename (i.e. the filename, without the directories), even though printing its length shows it's not just the bare name. (Chromium48 on Ubuntu 15.10). There's probably some backslash-escape processing at some point in cout, or between the program's stdout and the web browser.

What will you have? You'll probably end up with a default search and a search that you load from somewhere. Default search requires a default constructor, so make one like Dismissile has already suggested.

If you load the search criteria from elsewhere, then you should probably have some mapping logic.

If your action is not idempotent, then you MUST use POST. If you don't, you're just asking for trouble down the line. GET, PUT and DELETE methods are required to be idempotent. Imagine what would happen in your application if the client was pre-fetching every possible GET request for your service – if this would cause side effects visible to the client, then something's wrong.

I agree that sending a POST with a query string but without a body seems odd, but I think it can be appropriate in some situations.

Think of the query part of a URL as a command to the resource to limit the scope of the current request. Typically, query strings are used to sort or filter a GET request (like ?page=1&sort=title) but I suppose it makes sense on a POST to also limit the scope (perhaps like ?action=delete&id=5).

if you are using es6 this should work:

<input {...{ "customattribute": "somevalue" }} />

In html file:

<a [fragment]="test1" [routerLink]="['./']">Go to Test 1 section</a>

<section id="test1">...</section>
<section id="test2">...</section>

In ts file:

export class PageComponent implements AfterViewInit, OnDestroy {

  private destroy$$ = new Subject();
  private fragment$$ = new BehaviorSubject<string | null>(null);
  private fragment$ = this.fragment$$.asObservable();

  constructor(private route: ActivatedRoute) {
    this.route.fragment.pipe(takeUntil(this.destroy$$)).subscribe(fragment => {
      this.fragment$$.next(fragment);
    });
  }

  public ngAfterViewInit(): void {
    this.fragment$.pipe(takeUntil(this.destroy$$)).subscribe(fragment => {
      if (!!fragment) {
        document.querySelector('#' + fragment).scrollIntoView();
      }
    });
  }

  public ngOnDestroy(): void {
    this.destroy$$.next();
    this.destroy$$.complete();
  }
}

Simple you can try this

a=list(zip(portfolio, index))

12 to 24 hour time conversion and can be reversed if change time formate in output and input SimpleDateFormat class parameter

Test Data Input:

String input = "07:05:45PM"; timeCoversion12to24(input);

output

19:05:45

 public static String timeCoversion12to24(String twelveHoursTime) throws ParseException {

        //Date/time pattern of input date (12 Hours format - hh used for 12 hours)
        DateFormat df = new SimpleDateFormat("hh:mm:ssaa");

        //Date/time pattern of desired output date (24 Hours format HH - Used for 24 hours)
        DateFormat outputformat = new SimpleDateFormat("HH:mm:ss");
        Date date = null;
        String output = null;

        //Returns Date object
        date = df.parse(twelveHoursTime);

        //old date format to new date format
        output = outputformat.format(date);
        System.out.println(output);

        return output;
    }

I implemented this in the following way after receiving a NullPointerException from the accepted answer.

In my FXML:

<Button onMouseClicked="#onMouseClickedCancelBtn" text="Cancel">

In my Controller class:

@FXML public void onMouseClickedCancelBtn(InputEvent e) {
    final Node source = (Node) e.getSource();
    final Stage stage = (Stage) source.getScene().getWindow();
    stage.close();
}

Your bytes object is almost JSON, but it's using single quotes instead of double quotes, and it needs to be a string. So one way to fix it is to decode the bytes to str and replace the quotes. Another option is to use ast.literal_eval; see below for details. If you want to print the result or save it to a file as valid JSON you can load the JSON to a Python list and then dump it out. Eg,

import json

my_bytes_value = b'[{\'Date\': \'2016-05-21T21:35:40Z\', \'CreationDate\': \'2012-05-05\', \'LogoType\': \'png\', \'Ref\': 164611595, \'Classe\': [\'Email addresses\', \'Passwords\'],\'Link\':\'http://some_link.com\'}]'

# Decode UTF-8 bytes to Unicode, and convert single quotes 
# to double quotes to make it valid JSON
my_json = my_bytes_value.decode('utf8').replace("'", '"')
print(my_json)
print('- ' * 20)

# Load the JSON to a Python list & dump it back out as formatted JSON
data = json.loads(my_json)
s = json.dumps(data, indent=4, sort_keys=True)
print(s)

output

[{"Date": "2016-05-21T21:35:40Z", "CreationDate": "2012-05-05", "LogoType": "png", "Ref": 164611595, "Classe": ["Email addresses", "Passwords"],"Link":"http://some_link.com"}]
- - - - - - - - - - - - - - - - - - - - 
[
    {
        "Classe": [
            "Email addresses",
            "Passwords"
        ],
        "CreationDate": "2012-05-05",
        "Date": "2016-05-21T21:35:40Z",
        "Link": "http://some_link.com",
        "LogoType": "png",
        "Ref": 164611595
    }
]

As Antti Haapala mentions in the comments, we can use ast.literal_eval to convert my_bytes_value to a Python list, once we've decoded it to a string.

Generally, this problem arises because someone has saved data by printing its Python repr instead of using the json module to create proper JSON data. If it's possible, it's better to fix that problem so that proper JSON data is created in the first place.

If you only have one reference to a string and you concatenate another string to the end, CPython now special cases this and tries to extend the string in place.

The end result is that the operation is amortized O(n).

e.g.

s = ""
for i in range(n):
    s+=str(i)

used to be O(n^2), but now it is O(n).

From the source (bytesobject.c):

void
PyBytes_ConcatAndDel(register PyObject **pv, register PyObject *w)
{
    PyBytes_Concat(pv, w);
    Py_XDECREF(w);
}


/* The following function breaks the notion that strings are immutable:
   it changes the size of a string.  We get away with this only if there
   is only one module referencing the object.  You can also think of it
   as creating a new string object and destroying the old one, only
   more efficiently.  In any case, don't use this if the string may
   already be known to some other part of the code...
   Note that if there's not enough memory to resize the string, the original
   string object at *pv is deallocated, *pv is set to NULL, an "out of
   memory" exception is set, and -1 is returned.  Else (on success) 0 is
   returned, and the value in *pv may or may not be the same as on input.
   As always, an extra byte is allocated for a trailing \0 byte (newsize
   does *not* include that), and a trailing \0 byte is stored.
*/

int
_PyBytes_Resize(PyObject **pv, Py_ssize_t newsize)
{
    register PyObject *v;
    register PyBytesObject *sv;
    v = *pv;
    if (!PyBytes_Check(v) || Py_REFCNT(v) != 1 || newsize < 0) {
        *pv = 0;
        Py_DECREF(v);
        PyErr_BadInternalCall();
        return -1;
    }
    /* XXX UNREF/NEWREF interface should be more symmetrical */
    _Py_DEC_REFTOTAL;
    _Py_ForgetReference(v);
    *pv = (PyObject *)
        PyObject_REALLOC((char *)v, PyBytesObject_SIZE + newsize);
    if (*pv == NULL) {
        PyObject_Del(v);
        PyErr_NoMemory();
        return -1;
    }
    _Py_NewReference(*pv);
    sv = (PyBytesObject *) *pv;
    Py_SIZE(sv) = newsize;
    sv->ob_sval[newsize] = '\0';
    sv->ob_shash = -1;          /* invalidate cached hash value */

It's easy enough to verify empirically.

$ python -m timeit -s"s=''" "for i in xrange(10):s+='a'"
1000000 loops, best of 3: 1.85 usec per loop
$ python -m timeit -s"s=''" "for i in xrange(100):s+='a'"
10000 loops, best of 3: 16.8 usec per loop
$ python -m timeit -s"s=''" "for i in xrange(1000):s+='a'"
10000 loops, best of 3: 158 usec per loop
$ python -m timeit -s"s=''" "for i in xrange(10000):s+='a'"
1000 loops, best of 3: 1.71 msec per loop
$ python -m timeit -s"s=''" "for i in xrange(100000):s+='a'"
10 loops, best of 3: 14.6 msec per loop
$ python -m timeit -s"s=''" "for i in xrange(1000000):s+='a'"
10 loops, best of 3: 173 msec per loop

It's important however to note that this optimisation isn't part of the Python spec. It's only in the cPython implementation as far as I know. The same empirical testing on pypy or jython for example might show the older O(n**2) performance .

$ pypy -m timeit -s"s=''" "for i in xrange(10):s+='a'"
10000 loops, best of 3: 90.8 usec per loop
$ pypy -m timeit -s"s=''" "for i in xrange(100):s+='a'"
1000 loops, best of 3: 896 usec per loop
$ pypy -m timeit -s"s=''" "for i in xrange(1000):s+='a'"
100 loops, best of 3: 9.03 msec per loop
$ pypy -m timeit -s"s=''" "for i in xrange(10000):s+='a'"
10 loops, best of 3: 89.5 msec per loop

So far so good, but then,

$ pypy -m timeit -s"s=''" "for i in xrange(100000):s+='a'"
10 loops, best of 3: 12.8 sec per loop

ouch even worse than quadratic. So pypy is doing something that works well with short strings, but performs poorly for larger strings.

There are more suitable functions for this in os package. But if you have to use os.walk, here is what I come up with

def walkdir(dirname):
    for cur, _dirs, files in os.walk(dirname):
        pref = ''
        head, tail = os.path.split(cur)
        while head:
            pref += '---'
            head, _tail = os.path.split(head)
        print(pref+tail)
        for f in files:
            print(pref+'---'+f)

output:

>>> walkdir('.')

If you're using MySQL, there is a method REGEXP that you can use...

http://dev.mysql.com/doc/refman/5.1/en/regexp.html#operator_regexp

So then you would use:

SELECT * FROM `shirts` WHERE `colors` REGEXP '\b1\b'

Try out this one: "Pao" at http://pao-ide.info . It's still in development and not up to production use but it's quite unique in features. Basically, all the language constructs, such as assemblies, types, members, statements, expressions are treated as objects and are associated with rich operation options. You can enjoy features usually seen in graphical editors, such as multiple selection, multiple copy-paste, tagging, batch operation and very powerful search capability. It takes some getting used to but eventually might increase productivity. Right now, it only supports form applications though.

You can paste it like this:

= "2010-12-20" - 180

And don't forget to format the cell as a Date [CTRL]+[F1] / Number Tab

Note that according to the CSS3 spec, you do NOT have to wrap your layout in a table-style element. The browser will infer the existence of containing elements if they do not exist.

If you just want to add the same header to all the requests to the service, you can do it with out any coding!
Just add the headers node with required headers under the endpoint node in your client config file

<client>  
  <endpoint address="http://localhost/..." >  
    <headers>  
      <HeaderName>Value</HeaderName>

Python 3.10 (use |): Example for a function which takes a single argument that is either an int or str and returns either an int or str:

def func(arg: int | str) -> int | str:
              ^^^^^^^^^     ^^^^^^^^^ 
             type of arg   return type

Python 3.5 - 3.9 (use typing.Union):

from typing import Union
def func(arg: Union[int, str]) -> Union[int, str]:
              ^^^^^^^^^^^^^^^     ^^^^^^^^^^^^^^^ 
                type of arg         return type

For the special case of X | None you can use Optional[X].

     @Override
     public String toString() {
          return String.format("%15s /n %15d /n %15s /n %15s", name, age, Occupation, status);
     }

I'm hesitant to offer this as it misuses ye olde html. It's not a GOOD solution but it is a solution: use a table.

CSS:

table.navigation {
    width: 990px;
}
table.navigation td {
    text-align: center;
}

HTML:

<table cellpadding="0" cellspacing="0" border="0" class="navigation">
    <tr>
        <td>HOME</td>
        <td>ABOUT</td>
        <td>BASIC SERVICES</td>
        <td>SPECIALTY SERVICES</td>
        <td>OUR STAFF</td>
        <td>CONTACT US</td>
    </tr>
</table>

This is not what tables were created to do but until we can reliably perform the same action in a better way I guess it is just about permissable.

From this answer on Ask Ubuntu:

Tell grep to use the regular expressions as defined by Perl (Perl has \t as tab):

grep -P "\t" <file name>

Use the literal tab character:

grep "^V<tab>" <filename>

Use printf to print a tab character for you:

grep "$(printf '\t')" <filename>

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

There's a convenient method for this in MySql called GROUP_CONCAT. An equivalent for SQL Server doesn't exist, but you can write your own using the SQLCLR. Luckily someone already did that for you.

Your query then turns into this (which btw is a much nicer syntax):

SELECT CUSTOMFIELD, ISSUE, dbo.GROUP_CONCAT(STRINGVALUE)
FROM Jira.customfieldvalue
WHERE CUSTOMFIELD = 12534 AND ISSUE = 19602
GROUP BY CUSTOMFIELD, ISSUE

But please note that this method is good for at the most 100 rows within a group. Beyond that, you'll have major performance problems. SQLCLR aggregates have to serialize any intermediate results and that quickly piles up to quite a lot of work. Keep this in mind!

Interestingly the FOR XML doesn't suffer from the same problem but instead uses that horrendous syntax.

You are looking to use dirname. If you only want that one directory, you can use os.path.basename,

When put all together it looks like this:

os.path.basename(os.path.dirname('dir/sub_dir/other_sub_dir/file_name.txt'))

That should get you "other_sub_dir"

The following is not the ideal approach, but I originally proposed,using os.path.split, and simply get the last item. which would look like this:

os.path.split(os.path.dirname('dir/sub_dir/other_sub_dir/file_name.txt'))[-1]

Just in case of someone has the same problem. I'am using vim with YouCompleteMe, failed to start ycmd with this error message, what I did is: export LC_CTYPE="en_US.UTF-8", the problem is gone.

Use HttpWebRequest.BeginGetResponse()

HttpWebRequest webRequest;

void StartWebRequest()
{
    webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), null);
}

void FinishWebRequest(IAsyncResult result)
{
    webRequest.EndGetResponse(result);
}

The callback function is called when the asynchronous operation is complete. You need to at least call EndGetResponse() from this function.

For boot2docker, we can set it on /var/lib/boot2docker/profile, for instance:

ulimit -n 2018

Be warned not to set this limit too high as it will slow down apt-get! See bug #1332440. I had it with debian jessie.

If it's the visual appearance of a button you're looking for in a basic HTML anchor tag then you can use the Twitter Bootstrap framework to format any of the following common HTML type links/buttons to appear as a button. Please note the visual differences between version 2, 3 or 4 of the framework:

<a class="btn" href="">Link</a>
<button class="btn" type="submit">Button</button>
<input class="btn" type="button" value="Input">
<input class="btn" type="submit" value="Submit">

In Notepad++ you can select few lines and use CTRL+Q which will automaticaly make block comments for selected lines.

I was having the same problem, but using Long type. I changed for INT and it worked for me.

CREATE TABLE lists (
 id INT NOT NULL AUTO_INCREMENT,
 desc varchar(30),
 owner varchar(20),
 visibility boolean,
 PRIMARY KEY (id)
 );

Here is a really elegant solution from Chris Thielen ui-router-extras: $previousState

var previous = $previousState.get(); //Gets a reference to the previous state.

previous is an object that looks like: { state: fromState, params: fromParams } where fromState is the previous state and fromParams is the previous state parameters.

I have not been able to find a Firefox option equivalent of --disable-web-security or an addon that does that for me. I really needed it for some testing scenarios where modifying the web server was not possible. What did help was to use Fiddler to auto-modify web responses so that they have the correct headers and CORS is no longer an issue.

The steps are:

1. Open fiddler.

2. If on https go to menu Tools -> Options -> Https and tick the Capture & Decrypt https options

3. Go to menu Rules -> Customize rules. Modify the OnBeforeResponseFunction so that it looks like the following, then save:

    static function OnBeforeResponse(oSession: Session) {
       //....
       oSession.oResponse.headers.Remove("Access-Control-Allow-Origin");
       oSession.oResponse.headers.Add("Access-Control-Allow-Origin", "*");
       //...
    }
   

   This will make every web response to have the Access-Control-Allow-Origin: * header.

4. This still won't work as the OPTIONS preflight will pass through and cause the request to block before our above rule gets the chance to modify the headers. So to fix this, in the fiddler main window, on the right hand side there's an AutoResponder tab. Add a new rule and response: METHOD:OPTIONS https://yoursite.com/ with auto response: *CORSPreflightAllow and tick the boxes: "Enable Rules" and "Unmatched requests passthrough".

See picture below for reference:

The short answer is this:

    public bool Compare(byte[] b1, byte[] b2)
    {
        return Encoding.ASCII.GetString(b1) == Encoding.ASCII.GetString(b2);
    }

In such a way you can use the optimized .NET string compare to make a byte array compare without the need to write unsafe code. This is how it is done in the background:

private unsafe static bool EqualsHelper(String strA, String strB)
{
    Contract.Requires(strA != null);
    Contract.Requires(strB != null);
    Contract.Requires(strA.Length == strB.Length);

    int length = strA.Length;

Restarting the device works for me. Using adb install can get the apk installed, but it's annoying to use it everytime you launch the app when debugging within eclipse.

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

xsv is more than a viewer. I recommend it for most CSV task on the command line, especially when dealing with large datasets.

I have created a python module that is almost similar to the Properties class of Java ( Actually it is like the PropertyPlaceholderConfigurer in spring which lets you use ${variable-reference} to refer to already defined property )

EDIT : You may install this package by running the command(currently tested for python 3).
pip install property

The project is hosted on GitHub

Example : ( Detailed documentation can be found here )

Let's say you have the following properties defined in my_file.properties file

foo = I am awesome
bar = ${chocolate}-bar
chocolate = fudge

Code to load the above properties

from properties.p import Property

prop = Property()
# Simply load it into a dictionary
dic_prop = prop.load_property_files('my_file.properties')

What @Bogdan Maxim said. Or change to use InProc if you're not using an external sesssion state server.

<sessionState mode="InProc" timeout="20" cookieless="AutoDetect" />

Look here for more info on the SessionState directive.

To clarify earlier answers, the HTTP protocol is 'registered' with port 80, and HTTP over SSL (aka HTTPS) is registered with port 443.

Well known port numbers are documented by IANA.

If you mean "bypass logging software" on the web server, no. It will see the traffic coming from you through the proxy system's IP address, at least. If you're trying to circumvent controls put into place by your IT department, then you need to rethink this. If your IT department blocks traffic to port 80, 8080 or 443 anywhere outbound, there is a reason. Ask your IT director. If you need access to these ports outbound from your local workstation to do your job, make your case with them.

Installing a proxy server, or using a free proxy service, may be a violation of company policies and could put your employment at risk.

You can rename a file using git's mv command:

$ git mv file_from file_to

Example:

$ git mv helo.txt hello.txt

$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    helo.txt -> hello.txt
#

$ git commit -m "renamed helo.txt to hello.txt"
[master 14c8c4f] renamed helo.txt to hello.txt
 1 files changed, 0 insertions(+), 0 deletions(-)
 rename helo.txt => hello.txt (100%)

You can also use a pretty simple for loop:

for f in `find . -not -name "*Music*"`
do
    cp $f /target/dir
done

 if guess == number:
     print ("Good")
 elif guess == 2:
     print ("Bad")
 else:
     print ("Also bad")

Make sure you have your identation right. The syntax is ok.

I found a solution to my issue and after a request, will post it here to help others. Apologies if I missed any details, it's been a while since I worked on this solution.

The first thing that is required is to install Openoffice.org on the server. I requested my hosting provider to install the open office RPM on my VPS. This can be done through WHM directly.

Now that the server has the capability to handle MS Office files you are able to convert the files by executing command line instructions via PHP. To handle this, I found PyODConverter: https://github.com/mirkonasato/pyodconverter

I created a directory on the server and placed the PyODConverter python file within it. I also created a plain text file above the web root (I named it "adocpdf"), with the following command line instructions in it:

directory=$1
filename=$2
extension=$3
SERVICE='soffice'
if [ "`ps ax|grep -v grep|grep -c $SERVICE`" -lt 1 ]; then 
unset DISPLAY
/usr/bin/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard & 
sleep 5s
fi
python /home/website/python/DocumentConverter.py /home/website/$directory$filename$extension /home/website/$directory$filename.pdf

This checks that the openoffice.org libraries are running and then calls the PyODConverter script to process the file and output it as a PDF. The 3 variables on the first three lines are provided when the script is executed from with a PHP file. The delay ("sleep 5s") is used to ensure that openoffice.org has enough to time to initiate if required. I have used this for months now and the 5s gap seems to give enough breathing room.

The script will create a PDF version of the document in the same directory as the original.

Finally, initiating the conversion of a Word / Excel file from within PHP (I have it within a function that checks if the file we are dealing with is a word / excel document)...

//use openoffice.org
$output = array();
$return_var = 0;
exec("/opt/adocpdf {$directory} {$filename} {$extension}", $output, $return_var);

This PHP function is called once the Word / Excel file has been uploaded to the server. The 3 variables in the exec() call relate directly to the 3 at the start of the plain text script above. Note that the $directory variable requires no leading forward slash if the file for conversion is within the web root.

OK, that's it! Hopefully this will be useful to someone and save them the difficulties and learning curve I faced.

Use the insert method of a list:

l = list(...)
l.insert(index, item)

Alternatively, you can use a slice notation:

l[index:index] = [item]

If you want to move an item that's already in the list to the specified position, you would have to delete it and insert it at the new position:

l.insert(newindex, l.pop(oldindex))

In some circumstances it might be useful to simply remove the bindings and then re-apply:

ko.cleanNode(document.getElementById(element_id))
ko.applyBindings(viewModel, document.getElementById(element_id))

-XX:PermSize -XX:MaxPermSize are used to set size for Permanent Generation.

Permanent Generation: The Permanent Generation is where class files are kept. These are the result of compiled classes and JSP pages. If this space is full, it triggers a Full Garbage Collection. If the Full Garbage Collection cannot clean out old unreferenced classes and there is no room left to expand the Permanent Space, an Out-of- Memory error (OOME) is thrown and the JVM will crash.

Yes, MySQL has a REPLACE() function:

mysql> SELECT REPLACE('www.mysql.com', 'w', 'Ww');
    -> 'WwWwWw.mysql.com'

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace

Note that it's easier if you make that an alias when using SELECT

SELECT REPLACE(string_column, 'search', 'replace') as url....

In Linux/OSX I often use simple command curl -sI www.site.com

Use CURRENT_TIMESTAMP() or now()

Like

INSERT INTO servers (server_name, online_status, exchange, disk_space,
network_shares,date_time) VALUES('m1','ONLINE','ONLINE','100GB','ONLINE',now() )

or

INSERT INTO servers (server_name, online_status, exchange, disk_space,
network_shares,date_time) VALUES('m1', 'ONLINE', 'ONLINE', '100GB', 'ONLINE'
,CURRENT_TIMESTAMP() )

Replace date_time with the column name you want to use to insert the time.

The default timeout is 900 second. You can specify different timeout.

-T seconds
--timeout=seconds

The default is to retry 20 times. You can specify different tries.

-t number
--tries=number

Based on Bootstrap doc:

As of v3.1.0, .pull-right is deprecated on dropdown menus. use .dropdown-menu-right

eg:

<ul class="dropdown-menu dropdown-menu-right" role="menu" aria-labelledby="dLabel">

Here is a solution under 19API lvl:

• First of all. Make a Gson obj. --> Gson gson = new Gson();

• Second step is get your jsonObj as String with StringRequest(instead of JsonObjectRequest)

• The last step to get JsonArray...

YoursObjArray[] yoursObjArray = gson.fromJson(response, YoursObjArray[].class);

array1.NonIntersect(array2);

Nonintersect such operator is not present in Linq you should do

except -> union -> except

a.except(b).union(b.Except(a));

strncpy combats buffer overflow by requiring you to put a length in it. strcpy depends on a trailing \0, which may not always occur.

Secondly, why you chose to only copy 5 characters on 7 character string is beyond me, but it's producing expected behavior. It's only copying over the first n characters, where n is the third argument.

The n functions are all used as defensive coding against buffer overflows. Please use them in lieu of older functions, such as strcpy.

Coming late, but noUiSlider avoids having a jQuery-ui dependency, which the accepted answer does not. Its only "caveat" is IE support is for IE9 and newer, if legacy IE is a deal breaker for you.

It's also free, open source and can be used in commercial projects without restrictions.

Installation: Download noUiSlider, extract the CSS and JS file somewhere in your site file system, and then link to the CSS from head and to JS from body:

<!-- In <head> -->
<link href="nouislider.min.css" rel="stylesheet">

<!-- In <body> -->
<script src="nouislider.min.js"></script>

Example usage: Creates a slider which goes from 0 to 100, and starts set to 20-80.

HTML:

<div id="slider">
</div>

JS:

var slider = document.getElementById('slider');

noUiSlider.create(slider, {
    start: [20, 80],
    connect: true,
    range: {
        'min': 0,
        'max': 100
    }
});

Using a function converting an hexa string to byte[], you could do

byte[] CDRIVES = hexStringToByteArray("e04fd020ea3a6910a2d808002b30309d");

I'd suggest you use the function defined by Dave L in Convert a string representation of a hex dump to a byte array using Java?

I insert it here for maximum readability :

public static byte[] hexStringToByteArray(String s) {
    int len = s.length();
    byte[] data = new byte[len / 2];
    for (int i = 0; i < len; i += 2) {
        data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                             + Character.digit(s.charAt(i+1), 16));
    }
    return data;
}

If you let CDRIVES static and final, the performance drop is irrelevant.

View this picture to see how you can change the bundle identifier

Explanation:

1. Select your project form the leftmost project navigator
2. Under the General Tab, there is a section called Targets inside where you will see the name of your project. Click on the name.
3. Then you will be able to see the bundle identifier which you can change as below:

As you can see in the picture, the name of my App is PracticeApp. And my bundle identifier is: com.hello500.PracticeApp

In this case, You can change hello500 to change the bundle identifier of the app.

Will take you to the master branch.

git checkout master

To switch to other branches do (ignore the square brackets, it's just for emphasis purposes)

git checkout [the name of the branch you want to switch to]

To create a new branch use the -b like this (ignore the square brackets, it's just for emphasis purposes)

git checkout -b [the name of the branch you want to create]

Generic extension method (Gets Min and Max in one iteration):

public static class MyExtension
{
    public static (T Min, T Max) MinMax<T>(this IEnumerable<T> source) where T : IComparable<T>
    {
        if (source == null)
        {
            throw new ArgumentNullException(nameof(source));
        }

        T min = source.FirstOrDefault();
        T max = source.FirstOrDefault();

        foreach (T item in source)
        {
            if (item.CompareTo(min) == -1)
            {
                min = item;
            }
            if (item.CompareTo(max) == 1)
            {
                max = item;
            }
        }

        return (Min: min, Max: max);
    }

}

Exception handling in Thread : By default run() method doesn’t throw any exception, so all checked exceptions inside the run method has to be caught and handled there only and for runtime exceptions we can use UncaughtExceptionHandler. UncaughtExceptionHandler is an interface provided by Java to handle exceptions in a Thread run method. So we can implement this interface and set back our implementing class back to Thread object using setUncaughtExceptionHandler() method. But this handler has to be set before we call start() on the tread.

if we don’t set uncaughtExceptionHandler then the Threads ThreadGroup acts as a handler.

 public class FirstThread extends Thread {

int count = 0;

@Override
public void run() {
    while (true) {
        System.out.println("FirstThread doing something urgent, count : "
                + (count++));
        throw new RuntimeException();
    }

}

public static void main(String[] args) {
    FirstThread t1 = new FirstThread();
    t1.setUncaughtExceptionHandler(new UncaughtExceptionHandler() {
        public void uncaughtException(Thread t, Throwable e) {
            System.out.printf("Exception thrown by %s with id : %d",
                    t.getName(), t.getId());
            System.out.println("\n"+e.getClass());
        }
    });
    t1.start();
}
}

Instead of

Image.open(picture.jpg)
Img.show

You should have

from PIL import Image

#...

img = Image.open('picture.jpg')
img.show()

You should probably also think about an other system to show your messages, because this way it will be a lot of manual work. Look into string substitution (using %s or .format()).

I would imagine that it has to do with encoding. A char is 16 bytes and some encodings will use one byte for a character whereas another will use two or even more. When Java was originally designed, they assumed that any Unicode character would fit in 2 bytes, whereas now a Unicode character can require up to 4 bytes (UTF-32). There is no way for Scanner to represent a UTF-32 codepoint in a single char.

You can specify an encoding to Scanner when you construct an instance, and if not provided, it will use the platform character-set. But this still doesn't handle the issue with 3 or 4 byte Unicode characters, since they cannot be represented as a single char primitive (since char is only 16 bytes). So you would end up getting inconsistent results.

Here is the snippet of getting the attribute value of "lang" with XPath and VTD-XML.

import com.ximpleware.*;
public class getAttrVal {
    public static void main(String s[]) throws VTDException{
        VTDGen vg = new VTDGen();
        if (!vg.parseFile("input.xml", false)){
            return ;
        }
        VTDNav vn = vg.getNav();
        AutoPilot ap = new AutoPilot(vn);
        ap.selectXPath("/bookstore/book/title/@lang");
        System.out.println(" lang's value is ===>"+ap.evalXPathToString());
    }
}

String p1 = "example";
String p2 = "example";
String p3 = "example".intern();
String p4 = p2.intern();
String p5 = new String(p3);
String p6 = new String("example");
String p7 = p6.intern();

if (p1 == p2)
    System.out.println("p1 and p2 are the same");
if (p1 == p3)
    System.out.println("p1 and p3 are the same");
if (p1 == p4)
    System.out.println("p1 and p4 are the same");
if (p1 == p5)
    System.out.println("p1 and p5 are the same");
if (p1 == p6)
    System.out.println("p1 and p6 are the same");
if (p1 == p6.intern())
    System.out.println("p1 and p6 are the same when intern is used");
if (p1 == p7)
    System.out.println("p1 and p7 are the same");

When two strings are created independently, intern() allows you to compare them and also it helps you in creating a reference in the string pool if the reference didn't exist before.

When you use String s = new String(hi), java creates a new instance of the string, but when you use String s = "hi", java checks if there is an instance of word "hi" in the code or not and if it exists, it just returns the reference.

Since comparing strings is based on reference, intern() helps in you creating a reference and allows you to compare the contents of the strings.

When you use intern() in the code, it clears of the space used by the string referring to the same object and just returns the reference of the already existing same object in memory.

But in case of p5 when you are using:

String p5 = new String(p3);

Only contents of p3 are copied and p5 is created newly. So it is not interned.

So the output will be:

p1 and p2 are the same
p1 and p3 are the same
p1 and p4 are the same
p1 and p6 are the same when intern is used
p1 and p7 are the same

Lots of people advise you to use git update-index --assume-unchanged. Indeed, this may be a good solution, but only in the short run.

What you probably want to do is this: git update-index --skip-worktree.

(The third option, which you probably don't want is: git rm --cached. It will keep your local file, but will be marked as removed from the remote repository.)

Difference between the first two options?

• assume-unchanged is to temporary allow you to hide modifications from a file. If you want to hide modifications done to a file, modify the file, then checkout another branch, you'll have to use no-assume-unchanged then probably stash modifications done.
• skip-worktree will follow you whatever the branch you checkout, with your modifications!

Use case of assume-unchanged

It assumes this file should not be modified, and gives you a cleaner output when doing git status. But when checking out to another branch, you need to reset the flag and commit or stash changes before so. If you pull with this option activated, you'll need to solve conflicts and git won't auto merge. It actually only hides modifications (git status won't show you the flagged files).

I like to use it when I only want to stop tracking changes for a while + commit a bunch of files (git commit -a) related to the same modification.

Use case of skip-worktree

You have a setup class containing parameters (eg. including passwords) that your friends have to change accordingly to their setup.

• 1: Create a first version of this class, fill in fields you can fill and leave others empty/null.
• 2: Commit and push it to the remote server.
• 3: git update-index --skip-worktree MySetupClass.java
• 4: Update your configuration class with your own parameters.
• 5: Go back to work on another functionnality.

The modifications you do will follow you whatever the branch. Warning: if your friends also want to modify this class, they have to have the same setup, otherwise their modifications would be pushed to the remote repository. When pulling, the remote version of the file should overwrite yours.

PS: do one or the other, but not both as you'll have undesirable side-effects. If you want to try another flag, you should disable the latter first.

You can specify the colClasse for only one columns.

So in your example you should use:

data <- read.csv('test.csv', colClasses=c("time"="character"))

If you don't want to or simply can't use Linq you can also use the static Array.Exists(...); function:

https://msdn.microsoft.com/en-us/library/yw84x8be%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396

var arr = new string[]{"bird","foo","cat","dog"};

var catInside = Array.Exists( 
  arr, // your Array
  (s)=>{ return s == "cat"; } // the Predicate
);

When the Predicate do return true once catInside will be true as well.

I'm going to weigh in on this (Angular 7 Solution)

input [appFocus]="focus"....

import {AfterViewInit, Directive, ElementRef, Input,} from '@angular/core';

@Directive({
  selector: 'input[appFocus]',
})
export class FocusDirective implements AfterViewInit {

  @Input('appFocus')
  private focused: boolean = false;

  constructor(public element: ElementRef<HTMLElement>) {
  }

  ngAfterViewInit(): void {
    // ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked.

I faced this issue, when I was supplying the executable folder with a, by the .exe requested DLL. In my case, the DLL I supplied to the .exe was searching for another necessary DLL which was not available. The searching DLL was not capable of telling that it can not find the necessary DLL.

You might check the DLLs you're loading and the dependencies of these DLL's.

As most of the answers are suggesting to use the labels or return. The problem with labels is that it is not considered good practice in the industry because labels make your code difficult to read for other programmers. As for the return statement answers, The code example in the question is not inside some method. As the return statement will end the method and hence the loop will be broken with it. But that is not breaking off the loop that is ending the function. As, for the specific code example, this would be the good solution:

boolean endNestedLoop=false;

for (Type type : types) {

for (Type t : types2) {

if (some condition) {

endNestedLoop=true;

// Do something and break...

break; // Breaks out of the inner loop

}

if(endNestLoop)

break;

}

}

This way code is easy to read.

Here is an example which answers the question of returning the parameters of a class. Moreover, it still respects the chain of inheritance, i.e. only the parameters of the class itself are returned. The function get_params is added as a simple example, but other functionalities can be added thanks to the inspect module.

import inspect 

class Parent:
    @classmethod
    def get_params(my_class):
        return list(inspect.signature(my_class).parameters.keys())

class OtherParent:
    def __init__(self, a, b, c):
        pass

class Child(Parent, OtherParent):
    def __init__(self, x, y, z):
        pass

print(Child.get_params())
>>['x', 'y', 'z']

I use Strongloop's cli tools for that; see https://strongloop.com/strongblog/switch-between-configure-public-and-private-npm-registry/ for more information

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

However, the support for dashed lines depends on the selected terminal:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

Running

set terminal pngcairo dashed
set output 'test.png'
test
set output

gives:

whereas, the postscript terminal shows different dash patterns:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

Version 5.0

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• A new dashtype parameter was introduced:

  To get the predefined dash patterns, use e.g.

  plot x dashtype 2
  

  You can also specify custom dash patterns like

  plot x dashtype (3,5,10,5),\
       2*x dashtype '.-_'
  

• The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

  set for [i=1:8] linetype i dashtype i
  

• The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:

Alternate suggestion - if you're using Eclipse, you could set a breakpoint on NullPointerException itself (in the Debug perspective, go to the "Breakpoints" tab and click on the little icon that has a ! in it)

Check both the "caught" and "uncaught" options - now when you trigger the NPE, you'll immediately breakpoint and you can then step through and see how exactly it is handled and why you're not getting a stack trace.

For those who didn't follow the MS proscribed order (see Xv's answer) you can still fix the problem.

MSBuild uses the VCTargetsPath to locate default cpp properties but cannot because the registry lacks this String Value.

Check for the String Value

• Launch regedit
• Navigator to HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0
• Inspect VCTargetsPath key. The value should = "$(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\"

To fix

• Launch regedit Navigator to HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0
• Add String Value VCTargetsPath
• Set Value to "$(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\"

Note: HKLM stands for HKEY_LOCAL_MACHINE.

ugh, just to iterate over my own case, which gave out approximately the same error - in the Resource declaration (server.xml) make sure to NOT omit driverClassName, and that e.g. for Oracle it is "oracle.jdbc.OracleDriver", and that the right JAR file (e.g. ojdbc14.jar) exists in %CATALINA_HOME%/lib

The pythonic way to do it is from the PEP 8 style guide (where Yes means “recommended” and No means “not recommended”):

For sequences, (strings, lists, tuples), use the fact that empty sequences are false.

Yes: if not seq:
     if seq:

No:  if len(seq):
     if not len(seq):

One way I can imagine is to use a linked list to implement such a scenario, if you need all the numbers entered before the user enters something which indicates the loop termination. (posting as the first option, because have never done this for user input, it just seemed to be interesting. Wasteful but artistic)

Another way is to do buffered input. Allocate a buffer, fill it, re-allocate, if the loop continues (not elegant, but the most rational for the given use-case).

I don't consider the described to be elegant though. Probably, I would change the use-case (the most rational).

there's another one not mentioned here - nice thin - if you need that kind of look for your project: ╳

╳ or decimal: ╳

Range("C1:C10").Formula = "=A1+B1"

Simple as that.

It autofills (FillDown) the range with the formula.

Swift way to do it, you can call this from anywhere, it returns optional so watch out about that:

/// EZSwiftExtensions - Gives you the VC on top so you can easily push your popups
var topMostVC: UIViewController? {
    var presentedVC = UIApplication.sharedApplication().keyWindow?.rootViewController
    while let pVC = presentedVC?.presentedViewController {
        presentedVC = pVC
    }

    if presentedVC == nil {
        print("EZSwiftExtensions Error: You don't have any views set. You may be calling them in viewDidLoad. Try viewDidAppear instead.")
    }
    return presentedVC
}

Its included as a standard function in:

The angular-split component is not supported in Angular 6, so to make it compatible with Angular 6 install following dependency in your application

To get this working until it's updated use:

"dependencies": {
"angular-split": "1.0.0-rc.3",
"rxjs": "^6.2.2",
    "rxjs-compat": "^6.2.2",
}

@RequestMapping(path="/apps/add", method=RequestMethod.POST)
public String addApps(String appUrl, Model model, final RedirectAttributes redirectAttrs) {
    if (!validate(appUrl)) {
       redirectAttrs.addFlashAttribute("error", "Validation failed");
    }
    return "redirect:/apps/add"
} 

@RequestMapping(path="/apps/add", method=RequestMethod.GET)
public String addAppss(Model model) {
    String error = model.asMap().get("error");
}

you need to reconfigure your tnsnames.ora so that it can point to your hostname after that listener will be able to pick the new hostname. after which check the status of your listener lsnrctl status and start listener lsnrctl start then register your listener. Alter system register

Consider if your XML looks like below.

<Employees Id="1" Name="ABC">
  <Query>
    SELECT * FROM EMP WHERE ID=1 AND RES<>'GCF'
  <Query>
</Employees>

You cannot use the <> directly as it throws an error. In that case, you can use <> in replacement of that.

<Employees Id="1" Name="ABC">
  <Query>
    SELECT * FROM EMP WHERE ID=1 AND RES &#60;&#62; 'GCF'
  <Query>
</Employees>

It will look better if you reserve space for the common labels by making invisible labels for the subplot in the bottom left corner. It is also good to pass in the fontsize from rcParams. This way, the common labels will change size with your rc setup, and the axes will also be adjusted to leave space for the common labels.

fig_size = [8, 6]
fig, ax = plt.subplots(5, 2, sharex=True, sharey=True, figsize=fig_size)
# Reserve space for axis labels
ax[-1, 0].set_xlabel('.', color=(0, 0, 0, 0))
ax[-1, 0].set_ylabel('.', color=(0, 0, 0, 0))
# Make common axis labels
fig.text(0.5, 0.04, 'common X', va='center', ha='center', fontsize=rcParams['axes.labelsize'])
fig.text(0.04, 0.5, 'common Y', va='center', ha='center', rotation='vertical', fontsize=rcParams['axes.labelsize'])

You can set label's border via its underlying CALayer property:

#import <QuartzCore/QuartzCore.h>

myLabel.layer.borderColor = [UIColor greenColor].CGColor
myLabel.layer.borderWidth = 3.0

Swift 5:

myLabel.layer.borderColor = UIColor.darkGray.cgColor
myLabel.layer.borderWidth = 3.0

SELECT *
INTO newtable [IN externaldb]
FROM table1;
