You have to compile with Java 1.7. But if you have *.jsp files, you should also completely remove Java 1.8 from the system. If you use Mac, here is how you can do it.

It depends on what you mean by "convert an int to char".

If you simply want to cast the value in the int, you can cast it using Java's typecast notation:

int i = 97; // 97 is 'a' in ASCII
char c = (char) i; // c is now 'a'

If you mean transforming the integer 1 into the character '1', you can do it like this:

if (i >= 0 && i <= 9) {
char c = Character.forDigit(i, 10);
....
}

I know this post is older, but haven't seen a solution that provides the actual information, so I want to share what I use for SQL Server 2012 and above. the link below leads to the screenshot showing the information.

First (so no time is wasted):

SQL Server 2000:
SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')

SQL Server 2005+

The "SELECT SERVERPROPERTY('LicenseType'), SERVERPROPERTY('NumLicenses')" is not in use anymore. You can see more details on MSFT documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/serverproperty-transact-sql?view=sql-server-2017

SQL Server 2005 - 2008R2 you would have to:

Using PowerShell: https://www.ryadel.com/en/sql-server-retrieve-product-key-from-an-existing-installation/

Using TSQL (you would need to know the registry key path off hand): https://docs.microsoft.com/en-us/sql/relational-databases/system-dynamic-management-views/sys-dm-server-registry-transact-sql?view=sql-server-2017

SQL Server 2012+

Now, you can extract SQL Server Licensing information from the SQL Server Error Log, granted it may not be formatted the way you want, but the information is there and can be parsed, along with more descriptive information that you probably didn't expect.

EXEC sp_readerrorlog @p1 = 0
                    ,@p2 = 1
                    ,@p3 = N'licensing'

NOTE: I tried pasting the image directly, but since I am new at stakoverflow we have to follow the link below.

SQL Server License information via sp_readerrorlog

Play around with this jsFiddle example:

HTML:

<p id="foo" name="bar">Hello, world!</p>

jQuery:

$(function() {
    var name = $('#foo').attr('name');

    alert(name);
    console.log(name);
});

This uses jQuery's .attr() method to get value for the first element in the matched set.

While not specifically jQuery, the result is shown as an alert prompt and written to the browser's console.

Follow this step it will works fine. Go to Control panel-->Programs and features-->click Turn Windows features on and off--> see IIS is Checked Or Not If checked please unckeck IIS and restart the computer.After that Open services see Web Deployement Agent Service status if its started please stop.And also see WampAppache and WampSqlID if its not started please start manually. it will works for me.

I have done quite a bit of what you're talking about, and SOAP interoperability between platforms has one cardinal rule: CONTRACT FIRST. Do not derive your WSDL from code and then try to generate a client on a different platform. Anything more than "Hello World" type functions will very likely fail to generate code, fail to talk at runtime or (my favorite) fail to properly send or receive all of the data without raising an error.

That said, WSDL is complicated, nasty stuff and I avoid writing it from scratch whenever possible. Here are some guidelines for reliable interop of services (using Web References, WCF, Axis2/Java, WS02, Ruby, Python, whatever):

• Go ahead and do code-first to create your initial WSDL. Then, delete your code and re-generate the server class(es) from the WSDL. Almost every platform has a tool for this. This will show you what odd habits your particular platform has, and you can begin tweaking the WSDL to be simpler and more straightforward. Tweak, re-gen, repeat. You'll learn a lot this way, and it's portable knowledge.
• Stick to plain old language classes (POCO, POJO, etc.) for complex types. Do NOT use platform-specific constructs like List<> or DataTable. Even PHP associative arrays will appear to work but fail in ways that are difficult to debug across platforms.
• Stick to basic data types: bool, int, float, string, date(Time), and arrays. Odds are, the more particular you get about a data type, the less agile you'll be to new requirements over time. You do NOT want to change your WSDL if you can avoid it.
• One exception to the data types above - give yourself a NameValuePair mechanism of some kind. You wouldn't believe how many times a list of these things will save your bacon in terms of flexibility.
• Set a real namespace for your WSDL. It's not hard, but you might not believe how many web services I've seen in namespace "http://www.tempuri.org". Also, use a URN ("urn:com-myweb-servicename-v1", not a URL-based namespace ("http://servicename.myweb.com/v1". It's not a website, it's an abstract set of characters that defines a logical grouping. I've probably had a dozen people call me for support and say they went to the "website" and it didn't work.

</rant> :)

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

Groovy accepts nearly all Java syntax, so there is a spectrum of choices, as illustrated below:

// Java syntax 

Map<String,List> map1  = new HashMap<>();
List list1 = new ArrayList();
list1.add("hello");
map1.put("abc", list1); 
assert map1.get("abc") == list1;

// slightly less Java-esque

def map2  = new HashMap<String,List>()
def list2 = new ArrayList()
list2.add("hello")
map2.put("abc", list2)
assert map2.get("abc") == list2

// typical Groovy

def map3  = [:]
def list3 = []
list3 << "hello"
map3.'abc'= list3
assert map3.'abc' == list3

As with regular parameters, declaring an optional parameter is just a matter of the path property of a Route; any parameter that ends with a question mark will be treated as optional:

<Route path="to/page/:pathParam?" component={MyPage}/>

Try this code, it helped me!

$('.slider-selector').not('.slick-initialized').slick({
  dots: true,
  arrows: false,
  setPosition: true
});

You can do it programatically: Or without action bar

//It's enough to remove the line
     requestWindowFeature(Window.FEATURE_NO_TITLE);

//But if you want to display  full screen (without action bar) write too

     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
     WindowManager.LayoutParams.FLAG_FULLSCREEN);

     setContentView(R.layout.your_activity);

Please try this out to take into account all possible scenarios:

awk '{print $(NF-1)"\t"$NF}'  file

or

awk 'BEGIN{OFS="\t"}' file

or

awk '{print $(NF-1), $NF} {print $(NF-1), $NF}' file

The location of jfxrt.jar in Oracle Java 7 is:

<JRE_HOME>/lib/jfxrt.jar

The location of jfxrt.jar in Oracle Java 8 is:

<JRE_HOME>/lib/ext/jfxrt.jar

The <JRE_HOME> will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.

jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).

An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.

Use Oracle Java 8.

With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.

OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.

My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6

Yes, but only the Oracle JDK.

The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).

In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.

For big file use the following code (you are less memory hungry)

Parallel.ForEach(File.ReadLines(txtProxyListPath.Text), line => {
    //Your stuff
});

As per my understanding, this can be done in two ways :

1) You can use Directory Class with Getfiles method and traverse across all files to check our required extension.

Directory.GetFiles("your_folder_path)[i].Contains("*.txt")

2) You can use Path Class with GetExtension Method which takes file path as a parameter and verifies the extension.To get the file path, just have a looping condition that will fetch a single file and return the filepath that can be used for verification.

Path.GetExtension(your_file_path).Equals(".json")

Note : Both the logic has to be inside a looping condition.

billmanH's solution helped me but didn't work until i switched from:

n = data.loc[row,'json_column']

to:

n = data.iloc[[row]]['json_column']

here's the rest of it, converting to a dictionary is helpful for working with json data.

import json

for row in range(len(data)):
    n = data.iloc[[row]]['json_column'].item()
    jsonDict = json.loads(n)
    if ('mykey' in jsonDict):
        display(jsonDict['mykey'])

Mine was in: C:\NVPACK\android-sdk-windows\platform-tools

I found a way to display activity Indicator with minimum code:

first of all import your UI Kit

import UIKit;

Then you have to initiate activity indicator

let activityIndicator:UIActivityIndicatorView = UIActivityIndicatorView();

Then just copy paste this functions below which are self explainatory and call them whereever you need them:

func startLoading(){
    activityIndicator.center = self.view.center;
    activityIndicator.hidesWhenStopped = true;
    activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.gray;
    view.addSubview(activityIndicator);

    activityIndicator.startAnimating();
    UIApplication.shared.beginIgnoringInteractionEvents();

}

func stopLoading(){ 

    activityIndicator.stopAnimating();
    UIApplication.shared.endIgnoringInteractionEvents();

}

I'd like to supplement BalusC's answer with the mapping rules and an example.

Mapping rules from Servlet 2.5 specification:

1. Map exact URL
2. Map wildcard paths
3. Map extensions
4. Map to the default servlet

In our example, there're three servlets. / is the default servlet installed by us. Tomcat installs two servlets to serve jsp and jspx. So to map http://host:port/context/hello

1. No exact URL servlets installed, next.
2. No wildcard paths servlets installed, next.
3. Doesn't match any extensions, next.
4. Map to the default servlet, return.

To map http://host:port/context/hello.jsp

1. No exact URL servlets installed, next.
2. No wildcard paths servlets installed, next.
3. Found extension servlet, return.

The root of your problem is located here:

 unregisterReceiver(batteryNotifyReceiver);

If the receiver was already unregistered (probably in the code that you didn't include in this post) or was not registered, then call to unregisterReceiver throws IllegalArgumentException. In your case you need to just put special try/catch for this exception and ignore it (assuming you can't or don't want to control number of times you call unregisterReceiver on the same recevier).

Swift 4,

private func callNumber(phoneNumber:String) {

    if let phoneCallURL = URL(string: "telprompt://\(phoneNumber)") {

        let application:UIApplication = UIApplication.shared
        if (application.canOpenURL(phoneCallURL)) {
            if #available(iOS 10.0, *) {
                application.open(phoneCallURL, options: [:], completionHandler: nil)
            } else {
                // Fallback on earlier versions
                 application.openURL(phoneCallURL as URL)

            }
        }
    }
}

Another approach is to use timestamp values:

end_time.timestamp() - start_time.timestamp()

Yes it is possible to continue and to exit of a forEach loop.

To continue, you can use return, the loop will continue but the current function will end.

To exit of the loop, you can set the third parameter to 0 length, set to empty array. The loop will not continue, the current function do, so you can use "return" to finish, like exit in a normal for loop...

This:

[1,2,3,4,5,6,7,8,9,10].forEach((a,b,c) => {
    console.log(a);
    if(b == 2){return;}
    if(b == 4){c.length = 0;return;}
    console.log("next...",b);
});

will print this:

1
next... 0
2
next... 1
3
4
next... 3
5

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

In addition to the other responses:

Once obtained, Access Tokens are typically sent along with every request from Clients to protected Resource Servers. This induce a risk for access token stealing and replay (assuming of course that access tokens are of type "Bearer" (as defined in the initial RFC6750).

Examples of those risks, in real life:

• Resource Servers generally are distributed application servers and typically have lower security levels compared to Authorization Servers (lower SSL/TLS config, less hardening, etc.). Authorization Servers on the other hand are usually considered as critical Security infrastructure and are subject to more severe hardening.

• Access Tokens may show up in HTTP traces, logs, etc. that are collected legitimately for diagnostic purposes on the Resource Servers or clients. Those traces can be exchanged over public or semi-public places (bug tracers, service-desk, etc.).

• Backend RS applications can be outsourced to more or less trustworthy third-parties.

The Refresh Token, on the other hand, is typically transmitted only twice over the wires, and always between the client and the Authorization Server: once when obtained by client, and once when used by client during refresh (effectively "expiring" the previous refresh token). This is a drastically limited opportunity for interception and replay.

Last thought, Refresh Tokens offer very little protection, if any, against compromised clients.

Associative Arrays in JavaScript don't really work the same as they do in other languages. for each statements are complicated (because they enumerate inherited prototype properties). You could declare properties on an object/associative array as Pointy mentioned, but really for this sort of thing you should use an array with the push method:

jsArr = []; 

for (var i = 1; i <= 10; i++) { 
    jsArr.push('example ' + 1); 
} 

Just don't forget that indexed arrays are zero-based so the first element will be jsArr[0], not jsArr[1].

Imagine u have a list of email like below. not constrained to any programming language,

emailsList = ["[email protected]","[email protected]","[email protected]"]

Now following is JAVA code - for converting json to map

JSONObject jsonObj = new JSONObject().put("name","abc").put("email id",emailsList);
Map<String, Object> s = jsonObj.getMap();

Make a batch file and call the bacth file in Window.open. Here how it works

1. make a file in notepad
2. write your script : start wmplayer "\dotnet\sc\1234.mp4" /fullscreen
3. save as : test.bat in \dotnet\sc\test.bat

in html

window.open('file://dotnet/sc/test.bat')

Enjoy..

Try this

padding:8px;
overflow: hidden;
zoom: 1;
text-align: left;
font-size: 13px;
font-family: "Trebuchet MS",Arial,Sans;
line-height: 24px;
color: black;
border-bottom: solid 1px #BBB;
background:url('images/checked.gif') white no-repeat;

This is full css.. Why you use padding:0 8px, then override it with paddings? This is what you need...

By convention C strings are 'null-terminated'. That means that there's an extra byte at the end with the value of zero (0x00). Any function that does something with a string (like printf) will consider a string to end when it finds null. This also means that if your string is not null terminated, it will keep going until it finds a null character, which can produce some interesting results!

As the first item in your array is 0x00, it will be considered to be length zero (no characters).

If you defined your string to be:

char a[7]={0xdc,0x01,0x04,0x00};

e.g. null-terminated

then you can use strlen to measure the length of the string stored in the array.

sizeof measures the size of a type. It is not what you want. Also remember that the string in an array may be shorter than the size of the array.

I prefer using the following code to generate a decimal number up to fist decimal point. you can copy paste the 3rd line to add more numbers after decimal point by appending that number in string "combined". You can set the minimum and maximum value by changing the 0 and 9 to your preferred value.

Random r = new Random();
string beforePoint = r.Next(0, 9).ToString();//number before decimal point
string afterPoint = r.Next(0,9).ToString();//1st decimal point
//string secondDP = r.Next(0, 9).ToString();//2nd decimal point
string combined = beforePoint+"."+afterPoint;
decimalNumber= float.Parse(combined);
Console.WriteLine(decimalNumber);

I hope that it helped you.

You can use Embedded Profiler (free for Windows and Linux) which has an interface to a multiplatform timer (in a processor cycle count) and can give you a number of cycles per seconds:

EProfilerTimer timer;
timer.Start();

... // Your code here

const uint64_t number_of_elapsed_cycles = timer.Stop();
const uint64_t nano_seconds_elapsed =
    mumber_of_elapsed_cycles / (double) timer.GetCyclesPerSecond() * 1000000000;

Recalculation of cycle count to time is possibly a dangerous operation with modern processors where CPU frequency can be changed dynamically. Therefore to be sure that converted times are correct, it is necessary to fix processor frequency before profiling.

You need to do something when it fails to handle the issue. Right now you are returning the actual exception. For example, if its not a problem that the user exists already and you want to use it as a get_or_create function maybe you handle the issue by returning the existing user object.

try:
    user = iam_conn.create_user(UserName=username)
    return user
except botocore.exceptions.ClientError as e:

    #this exception could actually be other things other than exists, so you want to evaluate it further in your real code.
    if e.message.startswith(
        'enough of the exception message to identify it as the one you want')

        print('that user already exists.')
        user = iam_conn.get_user(UserName=username)
        return user

    elif e.message.some_other_condition:

         #something else
    else:
         #unhandled ClientError
         raise(e)
except SomeOtherExceptionTypeYouCareAbout as e:
    #handle it

# any unhandled exception will raise here at this point.
# if you want a general handler

except Exception as e:
    #handle it.

That said, maybe it is a problem for your app, in which case you want to want to put the exception handler around the code that called your create user function and let the calling function determine how to deal with it, for example, by asking the user to input another username, or whatever makes sense for your application.

I had a similar problem with crypto updates. A kludgy hack that gets around this is to include a '+ now() - now()' stunt at the end of the cell formula, with the setting as above to recalculate every minute. This worked for my price updates, but, definitely an ugly hack.

Whenever possible, avoid applying functions to a column in the where clause:

SELECT *
  FROM table_name
 WHERE timestamp >= UNIX_TIMESTAMP('2010-10-01 00:00:00') 
   AND timestamp <  UNIX_TIMESTAMP('2010-11-01 00:00:00');

Applying a function to the timestamp column (e.g., FROM_UNIXTIME(timestamp) = ...) makes indexing much harder.

Here's a fast multi-threaded port scanner:

from time import sleep
import socket, ipaddress, threading

max_threads = 50
final = {}
def check_port(ip, port):
    try:
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # TCP
        #sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
        socket.setdefaulttimeout(2.0) # seconds (float)
        result = sock.connect_ex((ip,port))
        if result == 0:
            # print ("Port is open")
            final[ip] = "OPEN"
        else:
            # print ("Port is closed/filtered")
            final[ip] = "CLOSED"
        sock.close()
    except:
        pass
port = 80
for ip in ipaddress.IPv4Network('192.168.1.0/24'): 
    threading.Thread(target=check_port, args=[str(ip), port]).start()
    #sleep(0.1)

# limit the number of threads.
while threading.active_count() > max_threads :
    sleep(1)

print(final)

Live Demo

You could use a nested query:

Select
  ColumnA,
  ColumnB,
  calccolumn1,
  calccolumn1 / ColumnC as calccolumn2
From (
  Select
    ColumnA,
    ColumnB,
    ColumnC,
    ColumnA + ColumnB As calccolumn1
  from t42
);

With a row with values 3, 4, 5 that gives:

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4

You can also just repeat the first calculation, unless it's really doing something expensive (via a function call, say):

Select
  ColumnA,
  ColumnB,
  ColumnA + ColumnB As calccolumn1,
  (ColumnA + ColumnB) / ColumnC As calccolumn2
from t42; 

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4 

What worked for me was:

<div style='display: inline-flex; width: 80px; height: 80px;'>
<img style='max-width: 100%; max-height: 100%' src='image file'>
</div>

inline-flex was required to keep the images from going outside of the div.

I am using Intellij Idea 2017 and I got into the same problem. What solved the problem for me was to simply

1. close the project in intelliJ
2. File -> New -> project from existing resources
3. use Import from external model (if any)
4. open the project again.

If you are using an array data source you can do something like below -

$(".select").select2({
    data: data_names
});
data_names.forEach(function(name) {
    if (name.selected) {
        $(".select").select2('val', name.id);
    }
});

This assumes that out of your data set the one item which you want to set as default has an additional attribute called selected and we use that to set the value.

Another option is an interesting open source project called ScriptCS. It uses some crafty techniques to allow you a development experience outside of Visual Studio while still being able to leverage NuGet to manage your dependencies. It's free, very easy to install using Chocolatey. You can check it out here http://scriptcs.net.

Another cool feature it has is the REPL from the command line. Which allows you to do stuff like this:

C:\> scriptcs
scriptcs (ctrl-c or blank to exit)

> var message = "Hello, world!";
> Console.WriteLine(message);
Hello, world!
> 

C:\>

You can create C# utility "scripts" which can be anything from small system tasks, to unit tests, to full on Web APIs. In the latest release I believe they're also allowing for hosting the runtime in your own apps.

Check out it development on the GitHub page too https://github.com/scriptcs/scriptcs

Here is the way I do it:

@Entity
public class ServerInstanceSeq
{
    @Id //mysql bigint(20)
    @SequenceGenerator(name="ServerInstanceIdSeqName", sequenceName="ServerInstanceIdSeq", allocationSize=20)
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="ServerInstanceIdSeqName")
    public Long id;

}

ServerInstanceSeq sis = new ServerInstanceSeq();
session.beginTransaction();
session.save(sis);
session.getTransaction().commit();
System.out.println("sis.id after save: "+sis.id);

How would you check if a variable is a dictionary in Python?

This is an excellent question, but it is unfortunate that the most upvoted answer leads with a poor recommendation, type(obj) is dict.

(Note that you should also not use dict as a variable name - it's the name of the builtin object.)

If you are writing code that will be imported and used by others, do not presume that they will use the dict builtin directly - making that presumption makes your code more inflexible and in this case, create easily hidden bugs that would not error the program out.

I strongly suggest, for the purposes of correctness, maintainability, and flexibility for future users, never having less flexible, unidiomatic expressions in your code when there are more flexible, idiomatic expressions.

is is a test for object identity. It does not support inheritance, it does not support any abstraction, and it does not support the interface.

So I will provide several options that do.

Supporting inheritance:

This is the first recommendation I would make, because it allows for users to supply their own subclass of dict, or a OrderedDict, defaultdict, or Counter from the collections module:

if isinstance(any_object, dict):

But there are even more flexible options.

Supporting abstractions:

from collections.abc import Mapping

if isinstance(any_object, Mapping):

This allows the user of your code to use their own custom implementation of an abstract Mapping, which also includes any subclass of dict, and still get the correct behavior.

Use the interface

You commonly hear the OOP advice, "program to an interface".

This strategy takes advantage of Python's polymorphism or duck-typing.

So just attempt to access the interface, catching the specific expected errors (AttributeError in case there is no .items and TypeError in case items is not callable) with a reasonable fallback - and now any class that implements that interface will give you its items (note .iteritems() is gone in Python 3):

try:
    items = any_object.items()
except (AttributeError, TypeError):
    non_items_behavior(any_object)
else: # no exception raised
    for item in items: ...

Perhaps you might think using duck-typing like this goes too far in allowing for too many false positives, and it may be, depending on your objectives for this code.

Conclusion

Don't use is to check types for standard control flow. Use isinstance, consider abstractions like Mapping or MutableMapping, and consider avoiding type-checking altogether, using the interface directly.

Having spent lot of time trying to fix this. I had no luck with any solution provide here or elsewhere.

But then later realised it wasn't so much as just solving the issue. But you also need to RESTART the VSCODE for it to take affect.

Don't buy any book use

MIT OCW

.

Here is a way so that when you select an option, it turns black. When you change it back to the placeholder, it turns back into the placeholder color (in this case red).

http://jsfiddle.net/wFP44/166/

It requires the options to have values.

$('select').on('change', function() {_x000D_
  if ($(this).val()) {_x000D_
return $(this).css('color', 'black');_x000D_
  } else {_x000D_
return $(this).css('color', 'red');_x000D_
  }_x000D_
});

select{_x000D_
  color: red;_x000D_
}_x000D_
select option { color: black; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select>_x000D_
<option value="">Pick one...</option>_x000D_
<option value="test1">Test 1</option>_x000D_
<option value="test2">Test 2</option>_x000D_
<option value="test3">Test 3</option>_x000D_
</select>

Another solution to this problem is to install PostgreSQL using Homebrew/linuxbrew:

brew install postgresql

As a matter of habit I don't like to use sudo unless I have to.

Using MoveToElement you will be able to find or click in whatever point you want, you have just to define the first parameter, it can be the session(winappdriver) or driver(in other ways) which is created when you instance WindowsDriver. Otherwise you can set as first parameter a grid (my case), a list, a panel or whatever you want.

Note: The top-left of your first parameter element will be the position X = 0 and Y = 0

   Actions actions = new Actions(this.session);
    int xPosition = this.session.FindElementsByAccessibilityId("GraphicView")[0].Size.Width - 530;
    int yPosition = this.session.FindElementsByAccessibilityId("GraphicView")[0].Size.Height- 150;
    actions.MoveToElement(this.xecuteClientSession.FindElementsByAccessibilityId("GraphicView")[0], xPosition, yPosition).ContextClick().Build().Perform();

The lambda you are passing to forEach() is evaluated for each element received from the stream. The iteration itself is not visible from within the scope of the lambda, so you cannot continue it as if forEach() were a C preprocessor macro. Instead, you can conditionally skip the rest of the statements in it.

i got this problems too. i got my project run in xcode4.2.1. i've read all comments up there, but no one is cool for me. after a while, i find that i commented a piece of code.

//self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

then i uncommented it. everything is ok for me. hope this would helpful for you guys.

If the space on that page is not disabled then put your button inside a div.

<div id="a1">
<button>Click here</button>
</div>

Using Jquery:

<script language="javascript">
$("#a1").hide();
</script>

Using JS:

<script language="javascript">
document.getElementById("a1").style.visibility = "hidden";
document.getElementById("a1").style.display = "none";
</script>

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

You can do either of the following:

1. Use css attribute "line-height" and set it per table row (), this will also vertically center the content within

2. Set "display" css attribute to "block" and as the following:

td 
{
  display: block;
  overflow-y: hidden;
  max-height: 20px;
}

good luck!

you can use delete operator to delete property by it's name

delete objectExpression.property

or iterate through the object and find the value you need and delete it:

for(prop in Obj){
   if(Obj.hasOwnProperty(prop)){
      if(Obj[prop] === 'myValue'){
        delete Obj[prop];
      }
   }
}

If you are using autolayout, set the vertical contentHuggingPriority to 1000, either in code or IB. In IB you may then have to remove a height constraint by setting it's priority to 1 and then deleting it.

C++11 allows you to do:

for (const auto& kv : myMap) {
    std::cout << kv.first << " has value " << kv.second << std::endl;
}

C++17 allows you to do:

for (const auto& [key, value] : myMap) {
    std::cout << key << " has value " << value << std::endl;
}

using structured binding.

UPDATE:

const auto is safer if you don't want to modify the map.

Im also got the same Error: cannot call methods on dialog prior to initialization; attempted to call method 'close'

what i did is i triggered the close button event which is in the dialog header like

this is working fine for me to close the dialog

function btnClose() {
$(".ui-dialog-titlebar-close").trigger('click');
}

As Matt Mombrea is correct for the server side, you might run into another problem which is whitelisting rejection.

You have to configure your phonegap.plist. (I am using a old version of phonegap)

For cordova, there might be some changes in the naming and directory. But the steps should be mostly the same.

First select Supporting files > PhoneGap.plist

then under "ExternalHosts"

Add a entry, with a value of perhaps "http://nqatalog.negroesquisso.pt" I am using * for debugging purposes only.

If you are on Mac, simply using System Preferences -> Languages and dragging the language to test to top (before English) will make sure the next time you open the App, the right locale is tried!!

I was looking for the same thing but I don't want to install any nuget or servicepack, so I found this solution, it is pretty simple and straight forward, using this discussion, I thought it would be so easy to run that WMIC command and get that value, here is the C# code. You only need to use System.Management namespace (and couple more standard namespaces for process and so on).

string fileName = Path.Combine(Environment.SystemDirectory, "wbem", "wmic.exe");
string arguments = @"cpu get NumberOfCores";

Process process = new Process
{
    StartInfo =
    {
        FileName = fileName,
        Arguments = arguments,
        UseShellExecute = false,
        CreateNoWindow = true,
        RedirectStandardOutput = true,
        RedirectStandardError = true
    }
};

process.Start();

StreamReader output = process.StandardOutput;
Console.WriteLine(output.ReadToEnd());


process.WaitForExit();
int exitCode = process.ExitCode;
process.Close();

Here is a more complete answer with regard to InnoDB. It is a bit of a lengthy process, but can be worth the effort.

Keep in mind that /var/lib/mysql/ibdata1 is the busiest file in the InnoDB infrastructure. It normally houses six types of information:

• Table Data
• Table Indexes
• MVCC (Multiversioning Concurrency Control) Data
  • Rollback Segments
  • Undo Space
• Table Metadata (Data Dictionary)
• Double Write Buffer (background writing to prevent reliance on OS caching)
• Insert Buffer (managing changes to non-unique secondary indexes)
• See the Pictorial Representation of ibdata1

InnoDB Architecture

Many people create multiple ibdata files hoping for better disk-space management and performance, however that belief is mistaken.

Can I run OPTIMIZE TABLE ?

Unfortunately, running OPTIMIZE TABLE against an InnoDB table stored in the shared table-space file ibdata1 does two things:

• Makes the table’s data and indexes contiguous inside ibdata1
• Makes ibdata1 grow because the contiguous data and index pages are appended to ibdata1

You can however, segregate Table Data and Table Indexes from ibdata1 and manage them independently.

Can I run OPTIMIZE TABLE with innodb_file_per_table ?

Suppose you were to add innodb_file_per_table to /etc/my.cnf (my.ini). Can you then just run OPTIMIZE TABLE on all the InnoDB Tables?

Good News : When you run OPTIMIZE TABLE with innodb_file_per_table enabled, this will produce a .ibd file for that table. For example, if you have table mydb.mytable witha datadir of /var/lib/mysql, it will produce the following:

• /var/lib/mysql/mydb/mytable.frm
• /var/lib/mysql/mydb/mytable.ibd

The .ibd will contain the Data Pages and Index Pages for that table. Great.

Bad News : All you have done is extract the Data Pages and Index Pages of mydb.mytable from living in ibdata. The data dictionary entry for every table, including mydb.mytable, still remains in the data dictionary (See the Pictorial Representation of ibdata1). YOU CANNOT JUST SIMPLY DELETE ibdata1 AT THIS POINT !!! Please note that ibdata1 has not shrunk at all.

InnoDB Infrastructure Cleanup

To shrink ibdata1 once and for all you must do the following:

1. Dump (e.g., with mysqldump) all databases into a .sql text file (SQLData.sql is used below)

2. Drop all databases (except for mysql and information_schema) CAVEAT : As a precaution, please run this script to make absolutely sure you have all user grants in place:

   mkdir /var/lib/mysql_grants
   cp /var/lib/mysql/mysql/* /var/lib/mysql_grants/.
   chown -R mysql:mysql /var/lib/mysql_grants
   

3. Login to mysql and run SET GLOBAL innodb_fast_shutdown = 0; (This will completely flush all remaining transactional changes from ib_logfile0 and ib_logfile1)

4. Shutdown MySQL

5. Add the following lines to /etc/my.cnf (or my.ini on Windows)

   [mysqld]
   innodb_file_per_table
   innodb_flush_method=O_DIRECT
   innodb_log_file_size=1G
   innodb_buffer_pool_size=4G
   

   (Sidenote: Whatever your set for innodb_buffer_pool_size, make sure innodb_log_file_size is 25% of innodb_buffer_pool_size.

   Also: innodb_flush_method=O_DIRECT is not available on Windows)

6. Delete ibdata* and ib_logfile*, Optionally, you can remove all folders in /var/lib/mysql, except /var/lib/mysql/mysql.

7. Start MySQL (This will recreate ibdata1 [10MB by default] and ib_logfile0 and ib_logfile1 at 1G each).

8. Import SQLData.sql

Now, ibdata1 will still grow but only contain table metadata because each InnoDB table will exist outside of ibdata1. ibdata1 will no longer contain InnoDB data and indexes for other tables.

For example, suppose you have an InnoDB table named mydb.mytable. If you look in /var/lib/mysql/mydb, you will see two files representing the table:

• mytable.frm (Storage Engine Header)
• mytable.ibd (Table Data and Indexes)

With the innodb_file_per_table option in /etc/my.cnf, you can run OPTIMIZE TABLE mydb.mytable and the file /var/lib/mysql/mydb/mytable.ibd will actually shrink.

I have done this many times in my career as a MySQL DBA. In fact, the first time I did this, I shrank a 50GB ibdata1 file down to only 500MB!

Give it a try. If you have further questions on this, just ask. Trust me; this will work in the short term as well as over the long haul.

CAVEAT

At Step 6, if mysql cannot restart because of the mysql schema begin dropped, look back at Step 2. You made the physical copy of the mysql schema. You can restore it as follows:

mkdir /var/lib/mysql/mysql
cp /var/lib/mysql_grants/* /var/lib/mysql/mysql
chown -R mysql:mysql /var/lib/mysql/mysql

Go back to Step 6 and continue

UPDATE 2013-06-04 11:13 EDT

With regard to setting innodb_log_file_size to 25% of innodb_buffer_pool_size in Step 5, that's blanket rule is rather old school.

Back on July 03, 2006, Percona had a nice article why to choose a proper innodb_log_file_size. Later, on Nov 21, 2008, Percona followed up with another article on how to calculate the proper size based on peak workload keeping one hour's worth of changes.

I have since written posts in the DBA StackExchange about calculating the log size and where I referenced those two Percona articles.

• Aug 27, 2012 : Proper tuning for 30GB InnoDB table on server with 48GB RAM
• Jan 17, 2013 : MySQL 5.5 - Innodb - innodb_log_file_size higher than 4GB combined?

Personally, I would still go with the 25% rule for an initial setup. Then, as the workload can more accurate be determined over time in production, you could resize the logs during a maintenance cycle in just minutes.

I haven't done Xcode in a bit, but I recommend that you disable "Zerolink" and "Load Symbols Lazily"; that will fix most problems. Zerolink is an abomination anyway.

You can directly go to Web IDE and upload your folder there.

Steps:

1. Go to Web IDE(Mostly located below the clone option).
2. Create new directory at your path
3. Upload your files and folders

In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.

To extend on what womp posted, you can pass new View Data while retaining the existing View Data if you use the constructor overload of the ViewDataDictionary like so:

Html.RenderPartial(
      "ProductImageForm", 
       image, 
       new ViewDataDictionary(this.ViewData) { { "index", index } }
); 

I did following modification to the Navigation Drawer Activity example in Android Studio. With support libraries 25.3.1.

MainActivity.java:

private DrawerLayout mDrawerLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.setDisplayHomeAsUpEnabled(true);
    }

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}

@Override
public void onBackPressed() {
    if (mDrawerLayout.isDrawerOpen(GravityCompat.END)) {
        mDrawerLayout.closeDrawer(GravityCompat.END);
    } else {
        super.onBackPressed();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int itemId = item.getItemId();
    switch (itemId) {
        case android.R.id.home:
            finish();
            return true;

        case R.id.action_right_drawer:
            if (mDrawerLayout.isDrawerOpen(GravityCompat.END)) {
                mDrawerLayout.closeDrawer(GravityCompat.END);
            } else {
                mDrawerLayout.openDrawer(GravityCompat.END);
            }
            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}

@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.

    mDrawerLayout.closeDrawer(GravityCompat.END);
    return true;
}

main.xml (download ic_menu_white_24px from https://material.io/icons/):

<?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item android:id="@+id/action_right_drawer"
        android:title="Drawer menu"
        android:icon="@drawable/ic_menu_white_24px"
        android:orderInCategory="100"
        app:showAsAction="always" />
</menu>

In activity_main.xml change

android:layout_gravity="start"

to

android:layout_gravity="end"

How about System.currentTimeMillis()?

From the JavaDoc:

Returns: the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC

Java 8 introduces the java.time framework, particularly the Instant class which "...models a ... point on the time-line...":

long now = Instant.now().toEpochMilli();

Returns: the number of milliseconds since the epoch of 1970-01-01T00:00:00Z -- i.e. pretty much the same as above :-)

Cheers,

This is the JSON String we want to decode :

{ 
   "stats": { 
       "sdr": "aa:bb:cc:dd:ee:ff", 
       "rcv": "aa:bb:cc:dd:ee:ff", 
       "time": "UTC in millis", 
       "type": 1, 
       "subt": 1, 
       "argv": [
          {"1": 2}, 
          {"2": 3}
       ]}
}

I store this string under the variable name "sJSON" Now, this is how to decode it :)

// Creating a JSONObject from a String 
JSONObject nodeRoot  = new JSONObject(sJSON); 

// Creating a sub-JSONObject from another JSONObject
JSONObject nodeStats = nodeRoot.getJSONObject("stats");

// Getting the value of a attribute in a JSONObject
String sSDR = nodeStats.getString("sdr");

It's a way how to pass arguments to functions. Passing by reference means the called functions' parameter will be the same as the callers' passed argument (not the value, but the identity - the variable itself). Pass by value means the called functions' parameter will be a copy of the callers' passed argument. The value will be the same, but the identity - the variable - is different. Thus changes to a parameter done by the called function in one case changes the argument passed and in the other case just changes the value of the parameter in the called function (which is only a copy). In a quick hurry:

• Java only supports pass by value. Always copies arguments, even though when copying a reference to an object, the parameter in the called function will point to the same object and changes to that object will be see in the caller. Since this can be confusing, here is what Jon Skeet has to say about this.
• C# supports pass by value and pass by reference (keyword ref used at caller and called function). Jon Skeet also has a nice explanation of this here.
• C++ supports pass by value and pass by reference (reference parameter type used at called function). You will find an explanation of this below.

Codes

Since my language is C++, i will use that here

// passes a pointer (called reference in java) to an integer
void call_by_value(int *p) { // :1
    p = NULL;
}

// passes an integer
void call_by_value(int p) { // :2
    p = 42;
}

// passes an integer by reference
void call_by_reference(int & p) { // :3
    p = 42;
}

// this is the java style of passing references. NULL is called "null" there.
void call_by_value_special(int *p) { // :4
    *p = 10; // changes what p points to ("what p references" in java)
    // only changes the value of the parameter, but *not* of 
    // the argument passed by the caller. thus it's pass-by-value:
    p = NULL;
}

int main() {
    int value = 10;
    int * pointer = &value;

    call_by_value(pointer); // :1
    assert(pointer == &value); // pointer was copied

    call_by_value(value); // :2
    assert(value == 10); // value was copied

    call_by_reference(value); // :3
    assert(value == 42); // value was passed by reference

    call_by_value_special(pointer); // :4
    // pointer was copied but what pointer references was changed.
    assert(value == 10 && pointer == &value);
}

And an example in Java won't hurt:

class Example {
    int value = 0;

    // similar to :4 case in the c++ example
    static void accept_reference(Example e) { // :1
        e.value++; // will change the referenced object
        e = null; // will only change the parameter
    }

    // similar to the :2 case in the c++ example
    static void accept_primitive(int v) { // :2
        v++; // will only change the parameter
    }        

    public static void main(String... args) {
        int value = 0;
        Example ref = new Example(); // reference

        // note what we pass is the reference, not the object. we can't 
        // pass objects. The reference is copied (pass-by-value).
        accept_reference(ref); // :1
        assert ref != null && ref.value == 1;

        // the primitive int variable is copied
        accept_primitive(value); // :2
        assert value == 0;
    }
}

This guy pretty much nails it:

http://javadude.com/articles/passbyvalue.htm

As of current edited version of the post, you call setInterval at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.

You only need to "prime" setInterval once. Remove it from function and place it inside onload instead of direct function call.

You can also declare it HTML safe from the code:

from flask import Markup
value = Markup('<strong>The HTML String</strong>')

Then pass that value to the templates and they don't have to |safe it.

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%') 
END

I think that there is a file open by some stream you are not aware of I had the same problem and solved it by closing all the streams that where pointing to the directory I wanted to delete.

Another way of doing using split method

public static void main(String[] args) {


    String s = "test string (67)";
    String[] ss;
    ss= s.split("\\(");
    ss = ss[1].split("\\)");

    System.out.println(ss[0]);
}

var dialogName = '#dialog_XYZ';
$.ajax({
        url: "/ajax_pages/my_page.ext",
        data: {....},
        success: function(data) {
          $(dialogName ).remove();

          $('BODY').append(data);

          $(dialogName )
            .dialog(options.dialogOptions);
        }
});

The Ajax-Request load the Dialog, add them to the Body of the current page and open the Dialog.

If you only whant to load the content you can do:

var dialogName = '#dialog_XYZ';
$.ajax({
            url: "/ajax_pages/my_page.ext",
            data: {....},
            success: function(data) {
              $(dialogName).append(data);

              $(dialogName )
                .dialog(options.dialogOptions);
            }
});

body {
    background-image: url(your image link);
    background-position: center center;
    background-repeat: no-repeat;
    background-attachment:fixed;
    background-size: cover;
    background-color: #464646;
}

If using backbone.js (which contains url anchor as route), url query string may appear:

1. before url anchor:

   var url = 'http://example.com?a=1&b=3#routepath/subpath';
   

2. after url anchor:

   var url = 'http://example.com#routepath/subpath?a=1&b=3';
   

Solution:

window.location.href.replace(window.location.search, '');
// run as: 'http://example.com#routepath/subpath?a=1&b=3'.replace('?a=1&b=3', '');

We can't talk about virtual members without referring to polymorphism. In fact, a function, property, indexer or event in a base class marked as virtual will allow override from a derived class.

By default, members of a class are non-virtual and cannot be marked as that if static, abstract, private, or override modifiers.

Example Let's consider the ToString() method in System.Object. Because this method is a member of System.Object it's inherited in all classes and will provide the ToString() methods to all of them.

namespace VirtualMembersArticle
{
    public class Company
    {
        public string Name { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Company company = new Company() { Name = "Microsoft" };
            Console.WriteLine($"{company.ToString()}");
            Console.ReadLine();
        }   
    }
}

The output of the previous code is:

VirtualMembersArticle.Company

Let's consider that we want to change the standard behavior of the ToString() methods inherited from System.Object in our Company class. To achieve this goal it's enough to use the override keyword to declare another implementation of that method.

public class Company
{
    ...
    public override string ToString()
    {
        return $"Name: {this.Name}";
    }         
}

Now, when a virtual method is invoked, the run-time will check for an overriding member in its derived class and will call it if present. The output of our application will then be:

Name: Microsoft

In fact, if you check the System.Object class you will find that the method is marked as virtual.

namespace System
{
    [NullableContextAttribute(2)]
    public class Object
    {
        ....
        public virtual string? ToString();
        ....
    }
}

Another solution would be dictdiffer (https://github.com/inveniosoftware/dictdiffer).

import dictdiffer                                          

a_dict = {                                                 
  'a': 'foo',
  'b': 'bar',
  'd': 'barfoo'
}                                                          

b_dict = {                                                 
  'a': 'foo',                                              
  'b': 'BAR',
  'c': 'foobar'
}                                                          

for diff in list(dictdiffer.diff(a_dict, b_dict)):         
    print diff

A diff is a tuple with the type of change, the changed value, and the path to the entry.

('change', 'b', ('bar', 'BAR'))
('add', '', [('c', 'foobar')])
('remove', '', [('d', 'barfoo')])

Given that what you want makes sense only when debugging, you could start SQLAlchemy with echo=True, to log all SQL queries. For example:

engine = create_engine(
    "mysql://scott:tiger@hostname/dbname",
    encoding="latin1",
    echo=True,
)

This can also be modified for just a single request:

echo=False – if True, the Engine will log all statements as well as a repr() of their parameter lists to the engines logger, which defaults to sys.stdout. The echo attribute of Engine can be modified at any time to turn logging on and off. If set to the string "debug", result rows will be printed to the standard output as well. This flag ultimately controls a Python logger; see Configuring Logging for information on how to configure logging directly.

Source: SQLAlchemy Engine Configuration

If used with Flask, you can simply set

app.config["SQLALCHEMY_ECHO"] = True

to get the same behaviour.

Out side the loop, set following.

cmbTripName.ValueMember = "FleetID"
cmbTripName.DisplayMember = "FleetName"

Now a day use of gravity start is best choise:

android:gravity="start"

For EditText (textarea):

<EditText
    android:id="@+id/EditText02"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:lines="5"
    android:gravity="start"
    android:inputType="textMultiLine"
/>

Ronal, to answer your question in the comment in my answer above:

function wasClicked(str)
{
  return str+' def';
}

Here is something to try, using interface and destructuring with default values. Please note that "lastName" is optional.

interface IName {
  firstName: string
  lastName?: string
}

function sayName(params: IName) {
  const { firstName, lastName = "Smith" } = params
  const fullName = `${firstName} ${lastName}`

  console.log("FullName-> ", fullName)
}

sayName({ firstName: "Bob" })

You can convert it with JS:

$('.image-class').each(function(){
    var processing = $(this).attr('src');
    $(this).parent().css({'background-image':'url('+processing+')'});
    $(this).hide();
});

If you just want to pass a class to a function, so that this function can create new instances of that class, just treat the class like any other value you would give as a parameter:

def printinstance(someclass):
  print someclass()

Result:

>>> printinstance(list)
[]
>>> printinstance(dict)
{}

Use this command:

egrep -lRZ "\.jpg|\.png|\.gif" . \
    | xargs -0 -l sed -i -e 's/\.jpg\|\.gif\|\.png/.bmp/g'

• egrep: find matching lines using extended regular expressions

  • -l: only list matching filenames

  • -R: search recursively through all given directories

  • -Z: use \0 as record separator

  • "\.jpg|\.png|\.gif": match one of the strings ".jpg", ".gif" or ".png"

  • .: start the search in the current directory

• xargs: execute a command with the stdin as argument

  • -0: use \0 as record separator. This is important to match the -Z of egrep and to avoid being fooled by spaces and newlines in input filenames.

  • -l: use one line per command as parameter

• sed: the stream editor

  • -i: replace the input file with the output without making a backup

  • -e: use the following argument as expression

  • 's/\.jpg\|\.gif\|\.png/.bmp/g': replace all occurrences of the strings ".jpg", ".gif" or ".png" with ".bmp"

Use DATE_ADD function

DATE_ADD(datecolumn, INTERVAL 30 MINUTE);

Still an issue in Microsoft Office 2016 release, rather disturbing for those of us working with gene names such as MARC1, MARCH1, SEPT1 etc. The solution I've found to be the most practical after generating a ".csv" file in R, that will then be opened/shared with Excel users:

1. Open the CSV file as text (notepad)
2. Copy it (ctrl+a, ctrl+c).
3. Paste it in a new excel sheet -it will all paste in one column as long text strings.
4. Choose/select this column.
5. Go to Data- "Text to columns...", on the window opened choose "delimited" (next). Check that "comma" is marked (marking it will already show the separation of the data to columns below) (next), in this window you can choose the column you want and mark it as text (instead of general) (Finish).

1. Restore Object From File

From Here you can deserialize an object from file in two way.

Solution-1: Read file into a string and deserialize JSON to a type

string json = File.ReadAllText(@"c:\myObj.json");
MyObject myObj = JsonConvert.DeserializeObject<MyObject>(json);

Solution-2: Deserialize JSON directly from a file

using (StreamReader file = File.OpenText(@"c:\myObj.json"))
{
    JsonSerializer serializer = new JsonSerializer();
    MyObject myObj2 = (MyObject)serializer.Deserialize(file, typeof(MyObject));
}

2. Save Object To File

from here you can serialize an object to file in two way.

Solution-1: Serialize JSON to a string and then write string to a file

string json = JsonConvert.SerializeObject(myObj);
File.WriteAllText(@"c:\myObj.json", json);

Solution-2: Serialize JSON directly to a file

using (StreamWriter file = File.CreateText(@"c:\myObj.json"))
{
    JsonSerializer serializer = new JsonSerializer();
    serializer.Serialize(file, myObj);
}

You can download Newtonsoft.Json from NuGet by following command

Install-Package Newtonsoft.Json

I have found that the simplest way to do this is to set onClick for each button in the xml

<Button
android:id="@+id/vrHelp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/ic_menu_help"
android:onClick="helpB" />

and then you can do a switch case like this

  public void helpB(View v) {
    Button clickedButton = (Button) v;
    switch (clickedButton.getId()) {
      case R.id.vrHelp:
        dosomething...
        break;

      case R.id.coHelp:
        dosomething...
        break;

      case R.id.ksHelp:
        dosomething...
        break;

      case R.id.uHelp:
        dosomething...
        break;

      case R.id.pHelp:
        dosomething...
        break;
    }
  }

Another way to get the same result:

date <- strptime(v,format="%Y%m%d")

I´d say MoDisco is by far the most powerful one (though probably not the easiest one to work with).

MoDisco is a generic reverse engineering framework (so that you can customize your reverse engineering project, with MoDisco you can even reverse engineer the behaviour of the java methods, not only the structure and signatures) but also includes some predefined features like the generation of class diagrams out of Java code that you need.

If you're trying to use twitter bootstrap popover with pjax, this worked for me:

App.Utils.Popover = {

  enableAll: function() {
    $('.pk-popover').popover(
      {
        trigger: 'click',
        html : true,
        container: 'body',
        placement: 'right',
      }
    );
  },

  bindDocumentClickEvent: function(documentObj) {
    $(documentObj).click(function(event) {
      if( !$(event.target).hasClass('pk-popover') ) {
        $('.pk-popover').popover('hide');
      }
    });
  }

};

$(document).on('ready pjax:end', function() {
  App.Utils.Popover.enableAll();
  App.Utils.Popover.bindDocumentClickEvent(this);
});

You can use:

var queryString = url.Substring(url.IndexOf('?')).Split('#')[0]
System.Web.HttpUtility.ParseQueryString(queryString)

Using functions with the ellipses is not very safe. If performance is not critical for log function consider using operator overloading as in boost::format. You could write something like this:

#include <sstream>
#include <boost/format.hpp>
#include <iostream>
using namespace std;

class formatted_log_t {
public:
    formatted_log_t(const char* msg ) : fmt(msg) {}
    ~formatted_log_t() { cout << fmt << endl; }

    template <typename T>
    formatted_log_t& operator %(T value) {
        fmt % value;
        return *this;
    }

protected:
    boost::format                fmt;
};

formatted_log_t log(const char* msg) { return formatted_log_t( msg ); }

// use
int main ()
{
    log("hello %s in %d-th time") % "world" % 10000000;
    return 0;
}

The following sample demonstrates possible errors with ellipses:

int x = SOME_VALUE;
double y = SOME_MORE_VALUE;
printf( "some var = %f, other one %f", y, x ); // no errors at compile time, but error at runtime. compiler do not know types you wanted
log( "some var = %f, other one %f" ) % y % x; // no errors. %f only for compatibility. you could write %1% instead.

A solution for me was to create a UILabel and add it to the UIButton as a subview. Finally I added a constraint to center it within the button.

UILabel * myTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 75, 75)];
myTextLabel.text = @"Some Text";
myTextLabel.translatesAutoresizingMaskIntoConstraints = false;

[myButton addSubView:myTextLabel];

// Add Constraints
[[myTextLabel centerYAnchor] constraintEqualToAnchor:myButton.centerYAnchor].active = true;
[[myTextLabel centerXAnchor] constraintEqualToAnchor:myButton.centerXAnchor].active = true; 

import os

path = chap_name

if not os.path.exists(path):
    os.makedirs(path)

filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
    temp_file.write(buff)

Key point is to use os.makedirs in place of os.mkdir. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html

Open the file in binary mode as you are storing binary (jpeg) data.

In response to Edit 2, if img_alt sometimes has '/' in it:

img_alt = os.path.basename(img_alt)

remember that the use of "live" is for "jQuery 1.3" or higher

in version "jQuery 1.4.3" or higher is used "delegate"

and version "jQuery 1.7 +" or higher is used "on"

$( selector ).live( events, data, handler ); // jQuery 1.3+
$( document ).delegate( selector, events, data, handler ); // jQuery 1.4.3+
$( document ).on( events, selector, data, handler ); // jQuery 1.7+

As of jQuery 1.7, the .live() method is deprecated.

There is no BI project in Visual Studio. Youll need to download SSDT. SSDT 2017 works fine :)

Use the jQuery hashchange event plugin instead. Regarding your full ajax navigation, try to have SEO friendly ajax. Otherwise your pages shown nothing in browsers with JavaScript limitations.

I've had success forcing the view to be ordered using

SELECT TOP 9999999 ... ORDER BY something

Unfortunately using SELECT TOP 100 PERCENT does not work due the issue here.

I'd download PuTTY and run a telnet session on port 80 to the webserver you want

HEAD /resource HTTP/1.1
Host: www.example.com

You could alternatively download Perl and try LWP's HEAD command. Or write your own script.

You essentially do inherit the constuctors in the sense that you can simply call super if and when appropriate, it's just that it would be error prone for reasons others have mentioned if it happened by default. The compiler can't presume when it is appropriate and when it isn't.

The job of the compiler is to provide as much flexibility as possible while reducing complexity and risk of unintended side-effects.

There may be a better way, but you can always copy the column into a new column, drop it and rename the new column back to the name of the first column.

to wit:

ALTER TABLE MyTable ADD NewColumnName DECIMAL(16, 2);
GO

UPDATE  MyTable
SET     NewColumnName = OldColumnName;
GO

ALTER TABLE CONTRACTS DROP COLUMN OldColumnName;
GO


EXEC sp_rename
    @objname = 'MyTable.NewColumnName',
    @newname = 'OldColumnName',
    @objtype = 'COLUMN'
GO

This was tested on SQL Server 2008 R2, but should work on SQL Server 2000+.

String someString = "" + c;
char c = someString.charAt(0);

I think excessive uses of global variables with static keyword will also leads to memory leakage at some point of instance in the applica

We can use ng-bind with <p> to display, we can use shortcut for ng-bind {{model}}, we cannot use ng-bind with html input controls, but we can use shortcut for ng-bind {{model}} with html input controls.

<input type="text" value="{{name}}" placeholder="Enter Something"/>
  Hello {{name}}
<p ng-bind="name"</p>

Create a Empty Guid or New Guid Using a Class...

Default value of Guid is 00000000-0000-0000-0000-000000000000

public class clsGuid  ---This is class Name
{
    public Guid MyGuid { get; set; }
}

static void Main(string[] args)
        {
            clsGuid cs = new clsGuid();   
            Console.WriteLine(cs.MyGuid); --this will give empty Guid  "00000000-0000-0000-0000-000000000000"

            cs.MyGuid = new Guid();
            Console.WriteLine(cs.MyGuid); ----this will also give empty Guid  "00000000-0000-0000-0000-000000000000"

            cs.MyGuid = Guid.NewGuid();
            Console.WriteLine(cs.MyGuid); --this way, it will give new guid  "d94828f8-7fa0-4dd0-bf91-49d81d5646af"

Regarding Jay Stevens answer: "The fonts available to use in an HTML file have to be present on the user's machine and accessible from the web browser, so unless you want to distribute the fonts to the user's machine via a separate external process, it can't be done." That's true.

But there is another way using javascript / canvas / flash - very good solution gives cufon: http://cufon.shoqolate.com/generate/ library that generates a very easy to use external fonts methods.

using sinon :

const mockAction = sinon.stub(MyService.prototype,'actionBeingCalled')
                     .returns(httpPromise(200));

Known that, httpPromise can be :

const httpPromise = (code) => new Promise((resolve, reject) =>
  (code >= 200 && code <= 299) ? resolve({ code }) : reject({ code, error:true })
);

Try this ...

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

Running an SQL query in PHPmyadmin to find and replace text in all wordpress blog posts, such as finding mysite.com/wordpress and replacing that with mysite.com/news Table in this example is tj_posts

There is a simple example of convert enumeration to list. for this i used Collections.list(enum) method.

public class EnumerationToList {

    public static void main(String[] args) {
        Vector<String> vt = new Vector<String>();
        vt.add("java");
        vt.add("php");
        vt.add("array");
        vt.add("string");
        vt.add("c");

        Enumeration<String> enm = vt.elements();
        List<String> ll = Collections.list(enm);
        System.out.println("List elements: " + ll);
    }

}

Reference : How to convert enumeration to list

If the reason for allowing if (aBooleanVariable) return; someMoreCode; is to allow flags, then the fact that if (true) return; someMoreCode; does not generate a compile time error seems like inconsistency in the policy of generating CodeNotReachable exception, since the compiler 'knows' that true is not a flag (not a variable).

Two other ways which might be interesting, but don't apply to switching off part of a method's code as well as if (true) return:

Now, instead of saying if (true) return; you might want to say assert false and add -ea OR -ea package OR -ea className to the jvm arguments. The good point is that this allows for some granularity and requires adding an extra parameter to the jvm invocation so there is no need of setting a DEBUG flag in the code, but by added argument at runtime, which is useful when the target is not the developer machine and recompiling & transferring bytecode takes time.

There is also the System.exit(0) way, but this might be an overkill, if you put it in Java in a JSP then it will terminate the server.

Apart from that Java is by-design a 'nanny' language, I would rather use something native like C/C++ for more control.

Try this:

Xcode >> Preferences >> Accounts

With sed -e '1,N d; M q' you'll print lines N+1 through M. This is probably a bit better then grep -C as it doesn't try to match lines to a pattern.

FYI - none of the above worked for me in 2012 SP1...simple solution was to embed credentials in the shared data source and then tell Safari to trust the SSRS server site. Then it worked great! Took days chasing down supposed solutions like above only to find out integrated security won't work reliably on Safari - you have to mess with the keychain on the mac and then still wouldn't work reliably.

You can set a bucket policy as detailed in this blog post:

http://ariejan.net/2010/12/24/public-readable-amazon-s3-bucket-policy/

As per @robbyt's suggestion, create a bucket policy with the following JSON:

{
  "Version": "2008-10-17",
  "Statement": [{
    "Sid": "AllowPublicRead",
    "Effect": "Allow",
    "Principal": { "AWS": "*" },
    "Action": ["s3:GetObject"],
    "Resource": ["arn:aws:s3:::bucket/*" ]
  }]
}

Important: replace bucket in the Resource line with the name of your bucket.

Not sure about Windows. But for mac users, use this:

pip install --upgrade pip==9.0.3

Views also break down very complex configuration and tables into managable chunks that are easily queried against. In our database, our entire table managment system is broken down into views from one large table.

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

This can work as well.

if (tabControl.SelectedTab.Text == "tabText" )
{
    .. do stuff
}

If you need the variable set before you're starting the notebook, the only solution which worked for me was env VARIABLE=$VARIABLE jupyter notebook with export VARIABLE=value in .bashrc.

In my case tensorflow needs the exported variable for successful importing it in a notebook.

If you don't have control over title element (like asp.net web form) here is some thing you can use

var app = angular.module("myApp")
    .config(function ($routeProvider) {
                $routeProvider.when('/', {
                                            title: 'My Page Title',
                                            controller: 'MyController',
                                            templateUrl: 'view/myView.html'
                                        })
                            .otherwise({ redirectTo: '/' });
    })
    .run(function ($rootScope) {
        $rootScope.$on("$routeChangeSuccess", function (event, currentRoute, previousRoute) {
            document.title = currentRoute.title;
        });
    });

There is no Javascript API to send ping frames or receive pong frames. This is either supported by your browser, or not. There is also no API to enable, configure or detect whether the browser supports and is using ping/pong frames. There was discussion about creating a Javascript ping/pong API for this. There is a possibility that pings may be configurable/detectable in the future, but it is unlikely that Javascript will be able to directly send and receive ping/pong frames.

However, if you control both the client and server code, then you can easily add ping/pong support at a higher level. You will need some sort of message type header/metadata in your message if you don't have that already, but that's pretty simple. Unless you are planning on sending pings hundreds of times per second or have thousands of simultaneous clients, the overhead is going to be pretty minimal to do it yourself.

In my case TLS1_2 was enabled both on client and server but the server was using MD5 while client disabled it. So, test both client and server on http://ssllabs.com or test using openssl/s_client to see what's happening. Also, check the selected cipher using Wireshark.

The dialog needs to be started only after the window states of the Activity are initialized This happens only after onresume.

So call

runOnUIthread(new Runnable(){

    showInfoMessageDialog("Please check your network connection","Network Alert");
});

in your OnResume function. Do not create dialogs in OnCreate
Edit:

use this

Handler h = new Handler();

h.postDelayed(new Runnable(){

        showInfoMessageDialog("Please check your network connection","Network Alert");
    },500);

in your Onresume instead of showonuithread

you can use cross apply:

select
    a.x,
    bb.y,
    bb.z
from
    a
    cross apply
    (   select b.y, b.z
        from b
        where b.v = a.v
    ) bb

If there will be no row from b to mach row from a then cross apply wont return row. If you need such a rows then use outer apply

If you need to find only one specific row for each of row from a, try:

    cross apply
    (   select top 1 b.y, b.z
        from b
        where b.v = a.v
        order by b.order
    ) bb

The syntax of the class creation statement:

class <ClassName>(superclass):
    #code follows

In the absence of any other superclasses that you specifically want to inherit from, the superclass should always be object, which is the root of all classes in Python.

object is technically the root of "new-style" classes in Python. But the new-style classes today are as good as being the only style of classes.

But, if you don't explicitly use the word object when creating classes, then as others mentioned, Python 3.x implicitly inherits from the object superclass. But I guess explicit is always better than implicit (hell)

Reference

I recently ran into this, and it ended up being because I had a convert statement on a null variable. Since that was causing errors, the entire print statement was rendering as null, and not printing at all.

Example - This will fail:

declare @myID int=null
print 'First Statement: ' + convert(varchar(4), @myID)

Example - This will print:

declare @myID int=null
print 'Second Statement: ' +  coalesce(Convert(varchar(4), @myID),'@myID is null')

1. In reference to the error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.

   That error means that the Data Source Name (DSN) you are specifying in your connection configuration is not being found in the windows registry.

   • It is important that your ODBC driver's executable and linking format (ELF) is the same as your application. In other words, you need a 32-bit driver for a 32-bit application or a 64-bit driver for a 64-bit application.

     If these do not match, it is possible to configure a DSN for a 32-bit driver and when you attempt to use that DSN in a 64-bit application, the DSN won't be found because the registry holds DSN information in different places depending on ELF (32-bit versus 64-bit).

     Be sure you are using the correct ODBC Administrator tool. On 32-bit and 64-bit Windows, the default ODBC Administrator tool is in c:\Windows\System32\odbcad32.exe. However, on a 64-bit Windows machine, the default is the 64-bit version. If you need to use the 32-bit ODBC Administrator tool on a 64-bit Windows system, you will need to run the one found here: C:\Windows\SysWOW64\odbcad32.exe

     Where I see this tripping people up is when a user uses the default 64-bit ODBC Administrator to configure a DSN; thinking it is for a 32-bit DSN. Then when the 32-bit application attempts to connect using that DSN, "Data source not found..." occurs.

   • It's also important to make sure the spelling of the DSN matches that of the configured DSN in the ODBC Administrator. One letter wrong is all it takes for a DSN to be mismatched.

     Here is an article that may provide some additional details

     It may not be the same product brand that you have, however; it is a generic problem that is encountered when using ODBC data source names.

2. In reference to the OLE DB Provider portion of your question, it appears to be a similar type of problem where the application is not able to locate the configuration for the specified provider.

Do you want to find elements that contain "match", or that equal "match"?

This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2):

//*[text()='match']

This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2):

//*[normalize-space(text())='match']

This will find all elements that contain 'match' in the text node value (matches random2 and random3):

//*[contains(text(),'match')]

This XPATH 2.0 solution uses the matches() function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^) or a word boundary (i.e. \W) and terminated by the end of the string (i.e. $) or a word boundary. The third parameter i evaluates the regex pattern case-insensitive. (matches random2)

//*[matches(text(),'(^|\W)match($|\W)','i')]

check that, in your "google-services.json" file your package_name is available or not

When calling Object.keys it returns a array of the object's keys.

Object.keys({ test: '', test2: ''}) // ['test', 'test2']

When you call Array#map the function you pass will give you 2 arguments;

1. the item in the array,
2. the index of the item.

When you want to get the data, you need to use item (or in the example below keyName) instead of i

{Object.keys(subjects).map((keyName, i) => (
    <li className="travelcompany-input" key={i}>
        <span className="input-label">key: {i} Name: {subjects[keyName]}</span>
    </li>
))}

To create a Flash object standart-compliant (with JavaScript however), I recommend you take a look at

Unobtrusive Flash Objects (UFO)

http://www.bobbyvandersluis.com/ufo/index.html

To permanently set the language syntax:
open settings.json file

*) format all txt files with javascript formatting

"files.associations": {
        "*.txt": "javascript"

 }

*) format all unsaved files (untitled-1 etc) to javascript:

"files.associations": {
        "untitled-*": "javascript"

 }

You can try

Random r = new Random();
int rInt = r.Next(0, 100); //for ints
int range = 100;
double rDouble = r.NextDouble()* range; //for doubles

Have a look at

Random Class, Random.Next Method (Int32, Int32) and Random.NextDouble Method

While configuring idea plugin in gradle, you should define output directories as follows.

idea{
    module{
        inheritOutputDirs = false
        outputDir = compileJava.destinationDir
        testOutputDir = compileTestJava.destinationDir
    }
}

Using Python to extract a value from the provided Json

Working sample:-

import json
import sys

//load the data into an element
data={"test1" : "1", "test2" : "2", "test3" : "3"}

//dumps the json object into an element
json_str = json.dumps(data)

//load the json to a string
resp = json.loads(json_str)

//print the resp
print (resp)

//extract an element in the response
print (resp['test1'])

in XAMPP the default root is "htdocs" inside the XAMPP folder, if you followed the instructions on the xampp homepage it would be "/opt/lampp/htdocs"

Variables in php are case sensitive. Please replace your while loop with following:

while ($rows = mysql_fetch_array($query)):

           $name = $rows['Name'];
           $address = $rows['Address'];
           $email = $rows['Email'];
           $subject = $rows['Subject'];
           $comment = $rows['Comment']

           echo "$name<br>$address<br>$email<br>$subject<br>$comment<br><br>";

           endwhile;

//Get
var p = $("#elementId");
var offset = p.offset();

//set
$("#secondElementId").offset({ top: offset.top, left: offset.left});

You can change the value in the XML like this:

<Button
    android:background="#FFFFFF"
     ../>

Here, you can add any other color, from the resources or hex.

Similarly, you can also change these values form the code like this:

demoButton.setBackgroundColor(Color.WHITE);

Another easy way is to make a drawable, customize the corners and shape according to your preference and set the background color and stroke of the drawable. For eg.

button_background.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="2dp" android:color="#ff207d94" />
    <corners android:radius="5dp" />
    <solid android:color="#FFFFFF" />
</shape>

And then set this shape as the background of your button.

<Button
    android:background="@drawable/button_background.xml"
     ../>

Hope this helps, good luck!

You can fix the issue by deleting the __MigrationHistory table which is created automatically in the database and logs any update in the database using code-first migrations. Here, in this case, you manually changed your database while EF assumed you had to do it with the migration tool. Deleting the table means to the EF that there are no updates and no need to do code-first migrations thus it works perfectly fine.

You should be able to accomplish this by using location.href

if(window.location.hostname == "www.myweb.com"){
   window.location.href = window.location.href + "?single";
}

You should use the logging library, which has this capability built in. You simply add handlers to a logger to determine where to send the output.

You could always use a subquery so you can use the alias; Of course, check the performance (Possible the db server will run both the same, but never hurts to verify):

SELECT ItemName, FirstLetter, COUNT(ItemName)
FROM (
    SELECT ItemName, SUBSTRING(ItemName, 1, 1) AS FirstLetter
    FROM table1
    ) ItemNames
GROUP BY ItemName, FirstLetter

An another way, you can do it easily with CMD on Windows

Put your installed version (mine is 11).

cd C:\Program Files\PostgreSQL\11\bin\

and run simple query

psql -U <postgre_username> -d <db_name> < <C:\path\data_dump.sql>

enter password then wait the final console message.

If you want to delete for example the last 3 commits, run the following command to remove the changes from the file system (working tree) and commit history (index) on your local branch:

git reset --hard HEAD~3

Then run the following command (on your local machine) to force the remote branch to rewrite its history:

git push --force

Congratulations! All DONE!

Some notes:

You can retrieve the desired commit id by running

git log

Then you can replace HEAD~N with <desired-commit-id> like this:

git reset --hard <desired-commit-id>

If you want to keep changes on file system and just modify index (commit history), use --soft flag like git reset --soft HEAD~3. Then you have chance to check your latest changes and keep or drop all or parts of them. In the latter case runnig git status shows the files changed since <desired-commit-id>. If you use --hard option, git status will tell you that your local branch is exactly the same as the remote one. If you don't use --hard nor --soft, the default mode is used that is --mixed. In this mode, git help reset says:

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated.

It's not possible to create a many-to-many relationship with a customized join table. In a many-to-many relationship EF manages the join table internally and hidden. It's a table without an Entity class in your model. To work with such a join table with additional properties you will have to create actually two one-to-many relationships. It could look like this:

public class Member
{
    public int MemberID { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }

    public virtual ICollection<MemberComment> MemberComments { get; set; }
}

public class Comment
{
    public int CommentID { get; set; }
    public string Message { get; set; }

    public virtual ICollection<MemberComment> MemberComments { get; set; }
}

public class MemberComment
{
    [Key, Column(Order = 0)]
    public int MemberID { get; set; }
    [Key, Column(Order = 1)]
    public int CommentID { get; set; }

    public virtual Member Member { get; set; }
    public virtual Comment Comment { get; set; }

    public int Something { get; set; }
    public string SomethingElse { get; set; }
}

If you now want to find all comments of members with LastName = "Smith" for example you can write a query like this:

var commentsOfMembers = context.Members
    .Where(m => m.LastName == "Smith")
    .SelectMany(m => m.MemberComments.Select(mc => mc.Comment))
    .ToList();

... or ...

var commentsOfMembers = context.MemberComments
    .Where(mc => mc.Member.LastName == "Smith")
    .Select(mc => mc.Comment)
    .ToList();

Or to create a list of members with name "Smith" (we assume there is more than one) along with their comments you can use a projection:

var membersWithComments = context.Members
    .Where(m => m.LastName == "Smith")
    .Select(m => new
    {
        Member = m,
        Comments = m.MemberComments.Select(mc => mc.Comment)
    })
    .ToList();

If you want to find all comments of a member with MemberId = 1:

var commentsOfMember = context.MemberComments
    .Where(mc => mc.MemberId == 1)
    .Select(mc => mc.Comment)
    .ToList();

Now you can also filter by the properties in your join table (which would not be possible in a many-to-many relationship), for example: Filter all comments of member 1 which have a 99 in property Something:

var filteredCommentsOfMember = context.MemberComments
    .Where(mc => mc.MemberId == 1 && mc.Something == 99)
    .Select(mc => mc.Comment)
    .ToList();

Because of lazy loading things might become easier. If you have a loaded Member you should be able to get the comments without an explicit query:

var commentsOfMember = member.MemberComments.Select(mc => mc.Comment);

I guess that lazy loading will fetch the comments automatically behind the scenes.

Edit

Just for fun a few examples more how to add entities and relationships and how to delete them in this model:

1) Create one member and two comments of this member:

var member1 = new Member { FirstName = "Pete" };
var comment1 = new Comment { Message = "Good morning!" };
var comment2 = new Comment { Message = "Good evening!" };
var memberComment1 = new MemberComment { Member = member1, Comment = comment1,
                                         Something = 101 };
var memberComment2 = new MemberComment { Member = member1, Comment = comment2,
                                         Something = 102 };

context.MemberComments.Add(memberComment1); // will also add member1 and comment1
context.MemberComments.Add(memberComment2); // will also add comment2

context.SaveChanges();

2) Add a third comment of member1:

var member1 = context.Members.Where(m => m.FirstName == "Pete")
    .SingleOrDefault();
if (member1 != null)
{
    var comment3 = new Comment { Message = "Good night!" };
    var memberComment3 = new MemberComment { Member = member1,
                                             Comment = comment3,
                                             Something = 103 };

    context.MemberComments.Add(memberComment3); // will also add comment3
    context.SaveChanges();
}

3) Create new member and relate it to the existing comment2:

var comment2 = context.Comments.Where(c => c.Message == "Good evening!")
    .SingleOrDefault();
if (comment2 != null)
{
    var member2 = new Member { FirstName = "Paul" };
    var memberComment4 = new MemberComment { Member = member2,
                                             Comment = comment2,
                                             Something = 201 };

    context.MemberComments.Add(memberComment4);
    context.SaveChanges();
}

4) Create relationship between existing member2 and comment3:

var member2 = context.Members.Where(m => m.FirstName == "Paul")
    .SingleOrDefault();
var comment3 = context.Comments.Where(c => c.Message == "Good night!")
    .SingleOrDefault();
if (member2 != null && comment3 != null)
{
    var memberComment5 = new MemberComment { Member = member2,
                                             Comment = comment3,
                                             Something = 202 };

    context.MemberComments.Add(memberComment5);
    context.SaveChanges();
}

5) Delete this relationship again:

var memberComment5 = context.MemberComments
    .Where(mc => mc.Member.FirstName == "Paul"
        && mc.Comment.Message == "Good night!")
    .SingleOrDefault();
if (memberComment5 != null)
{
    context.MemberComments.Remove(memberComment5);
    context.SaveChanges();
}

6) Delete member1 and all its relationships to the comments:

var member1 = context.Members.Where(m => m.FirstName == "Pete")
    .SingleOrDefault();
if (member1 != null)
{
    context.Members.Remove(member1);
    context.SaveChanges();
}

This deletes the relationships in MemberComments too because the one-to-many relationships between Member and MemberComments and between Comment and MemberComments are setup with cascading delete by convention. And this is the case because MemberId and CommentId in MemberComment are detected as foreign key properties for the Member and Comment navigation properties and since the FK properties are of type non-nullable int the relationship is required which finally causes the cascading-delete-setup. Makes sense in this model, I think.

set the overflow property of a containing div to scroll.

Problem 1:

The generated HTML you're getting is normal. Apparently it's a feature of Angular to be able to use any kind of object as value for a select. Angular does the mapping between the HTML option-value and the value in the ng-model. Also see Umur's comment in this question: How do I set the value property in AngularJS' ng-options?

Problem 2:

Make sure you're using the following ng-options:

<select ng-model="object.item" ng-options="item.id as item.name for item in list" />

And put this in your controller to select a default value:

object.item = 4

I think that it's around 2GB. While the answer by Pete Kirkham is very interesting and probably holds truth, I have allocated upwards of 3GB without error, however it did not use 3GB in practice. That might explain why you were able to allocate 2.5 GB on 2GB RAM with no swap space. In practice, it wasn't using 2.5GB.

I found the xmessage command, which is sort of good enough.

Had the same problem. Solved as given below. Use command :

sudo tail -f /var/log/messages|grep -i mysql

to check if SELinux policy is causing the issue. If so, first check if SELinux policy is enabled using command #sestatus. If it shows enabled, then disable it. To disable:

1. # vi /etc/sysconfig/selinux
2. change 'SELINUX=enforcing' to 'SELINUX=disabled'
3. restart linux
4. check with sestatus and it should show "disabled"

Uninstall and reinstall mysql. It should be working.

Sorry for the necropost, but these solutions did not work for me. I'm on postgres 10. On Linux:

1. I had to change directory to my pg_hba.conf.
2. I had to edit the file to change method from peer to md5 as stated here
3. Restart the service: service postgresql-10 restart

4. Change directory to where my backup.sql was located and execute:
   psql postgres -d database_name -1 -f backup.sql

   -database_name is the name of my database

   -backup.sql is the name of my .sql backup file.

If your proxy is configured correctly, then pip version 1.5.6 will handle this correctly. The bug was resolved.

You can upgrade pip with easy_install pip==1.5.6

Basically, pip comes with python itself.Therefore it carries no meaning for using pip itself to install or upgrade python. Thus,try to install python through installer itself,visit the site "https://www.python.org/downloads/" for more help. Thank you.

To get the value from the servlet from POST command, you can follow the approach as explained on this post by using request.getParameter(key) format which will return the value you want.

There's a CodeProject article for an ID3 reader. And a thread at kixtart.org that has more information for other properties. Basically, you need to call the GetDetailsOf() method on the folder shell object for shell32.dll.

Update after 6 years: now I consider that the approach below is pretty bad. To create a retry logic we should consider to use a library like Polly.

My async implementation of the retry method:

public static async Task<T> DoAsync<T>(Func<dynamic> action, TimeSpan retryInterval, int retryCount = 3)
    {
        var exceptions = new List<Exception>();

        for (int retry = 0; retry < retryCount; retry++)
        {
            try
            {
                return await action().ConfigureAwait(false);
            }
            catch (Exception ex)
            {
                exceptions.Add(ex);
            }

            await Task.Delay(retryInterval).ConfigureAwait(false);
        }
        throw new AggregateException(exceptions);
    }

Key points: I used .ConfigureAwait(false); and Func<dynamic> instead Func<T>

In my case, pausing dropbox sync solved the issue

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

I had the same problem. with 64bit os all should be 64bit. Java and Eclipse. I tried all the methods in stackoverflow and also in youtube. non of them worked for me untill i found this easy method.

I installed 64bit java form Cnet download and the problem was automatically fixed. I mentioned the source because it is too easy to google and go to first Cnet lint rather than oficial site if you are a new bee.

p.s. if you have Android ADT bundle and tried to open eclipse from it and got the same error, you can fix that problem too with this method.

There is a close() function for InfoWindows. Just keep track of the last opened window, and call the close function on it when a new window is created.

Only for Ubuntu/ Debian users: There are some specific things to do for ubuntu to make USB debugging work: described here: https://developer.android.com/studio/run/device Here are the two steps mentioned. Run this two command in terminal:

sudo usermod -aG plugdev $LOGNAME
sudo apt-get install android-sdk-platform-tools-common

I'm surprised no one has suggested one of the most obvious ways to go:

public class TimeDependentClass
{
    public void TimeDependentMethod(DateTime someTime)
    {
        if (GetCurrentTime() > someTime) DoSomething();
    }

    protected virtual DateTime GetCurrentTime()
    {
        return DateTime.Now; // or UtcNow
    }
}

Then you can simply override this method in your test double.

I also kind of like injecting a TimeProvider class in some cases, but for others, this is more than enough. I'd probably favor the TimeProvider version if you need to reuse this in several classes though.

EDIT: For anyone interested, this is called adding a "seam" to your class, a point where you can hook in to it's behavior to modify it (for testing purposes or otherwise) without actually having to change the code in the class.

Even though this is a really old question, this may work.

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

Further information

You may also be interested in reading an answer to a related question.

The difference is that you can lock and unlock a std::unique_lock. std::lock_guard will be locked only once on construction and unlocked on destruction.

So for use case B you definitely need a std::unique_lock for the condition variable. In case A it depends whether you need to relock the guard.

std::unique_lock has other features that allow it to e.g.: be constructed without locking the mutex immediately but to build the RAII wrapper (see here).

std::lock_guard also provides a convenient RAII wrapper, but cannot lock multiple mutexes safely. It can be used when you need a wrapper for a limited scope, e.g.: a member function:

class MyClass{
    std::mutex my_mutex;
    void member_foo() {
        std::lock_guard<mutex_type> lock(this->my_mutex);            
        /*
         block of code which needs mutual exclusion (e.g. open the same 
         file in multiple threads).
        */

        //mutex is automatically released when lock goes out of scope
    }           
};

To clarify a question by chmike, by default std::lock_guard and std::unique_lock are the same. So in the above case, you could replace std::lock_guard with std::unique_lock. However, std::unique_lock might have a tad more overhead.

Note that these days (since, C++17) one should use std::scoped_lock instead of std::lock_guard.

Create mysql connection with following parameter. "'raise_on_warnings': False". It will ignore the warning. e.g.

config = {'user': 'user','password': 'passwd','host': 'localhost','database': 'db',   'raise_on_warnings': False,}
cnx = mysql.connector.connect(**config)

It depends on what you mean with "is an object". If you want everything that is not a primitive, i.e. things that you can set new properties on, this should do the trick:

function isAnyObject(value) {
    return value != null && (typeof value === 'object' || typeof value === 'function');
}

It excludes the primitives (plain numbers/NaN/Infinity, plain strings, symbols, true/false, undefined and null) but should return true for everything else (including Number, Boolean and String objects). Note that JS does not define what "host" objects, such as window or console, should return when used with typeof, so those are hard to cover with a check like this.

If you want to know whether something is a "plain" object, i.e. it was created as a literal {} or with Object.create(null), you might do this:

function isPlainObject(value) {
    if (Object.prototype.toString.call(value) !== '[object Object]') {
        return false;
    } else {
        var prototype = Object.getPrototypeOf(value);
        return prototype === null || prototype === Object.prototype;
    }
}

Edit 2018: Because Symbol.toStringTag now allows customizing the output of Object.prototype.toString.call(...), the isPlainObject function above might return false in some cases even when the object started its life as a literal. Arguably, by convention an object with a custom string tag isn't exactly a plain object any more, but this has further muddied the definition of what a plain object even is in Javascript.

In Pandas, I like to use the shape attribute to get number of rows.

df[df.A > 0].shape[0]

gives the number of rows matching the condition A > 0, as desired.

Lazy man can use this lib, Just import inside your project and

ImageView mImageView;
PhotoViewAttacher mAttacher;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Any implementation of ImageView can be used!
    mImageView = (ImageView) findViewById(R.id.iv_photo);

    // Set the Drawable displayed
    Drawable bitmap = getResources().getDrawable(R.drawable.wallpaper);
    mImageView.setImageDrawable(bitmap);

    // Attach a PhotoViewAttacher, which takes care of all of the zooming functionality.
    mAttacher = new PhotoViewAttacher(mImageView);
}


// If you later call mImageView.setImageDrawable/setImageBitmap/setImageResource/etc then you just need to call
mAttacher.update();

StackTrace

This Highly depends on what you are looking for... But this should get the class and method that called this method within this object directly.

• index 0 = Thread
• index 1 = this
• index 2 = direct caller, can be self.
• index 3 ... n = classes and methods that called each other to get to the index 2 and below.

For Class/Method/File name:

Thread.currentThread().getStackTrace()[2].getClassName();
Thread.currentThread().getStackTrace()[2].getMethodName();
Thread.currentThread().getStackTrace()[2].getFileName();

For Class:

Class.forName(Thread.currentThread().getStackTrace()[2].getClassName())

FYI: Class.forName() throws a ClassNotFoundException which is NOT runtime. Youll need try catch.

Also, if you are looking to ignore the calls within the class itself, you have to add some looping with logic to check for that particular thing.

Something like... (I have not tested this piece of code so beware)

StackTraceElement[] stes = Thread.currentThread().getStackTrace();
for(int i=2;i<stes.length;i++)
  if(!stes[i].getClassName().equals(this.getClass().getName()))
    return stes[i].getClassName();

StackWalker

StackWalker StackFrame

Note that this is not an extensive guide but an example of the possibility.

Prints the Class of each StackFrame (by grabbing the Class reference)

StackWalker.getInstance(Option.RETAIN_CLASS_REFERENCE)
    .forEach(frame -> System.out.println(frame.getDeclaringClass()));

Does the same thing but first collects the stream into a List. Just for demonstration purposes.

StackWalker.getInstance(Option.RETAIN_CLASS_REFERENCE)
    .walk(stream -> stream.collect(Collectors.toList()))
    .forEach(frame -> System.out.println(frame.getDeclaringClass()));

[Updated solution]

can be used with "Normalize" (Canonical decomposition) and "replaceAll", to replace it with the appropriate characters.

import java.text.Normalizer;
import java.text.Normalizer.Form;
import java.util.regex.Pattern;

public final class NormalizeUtils {

    public static String normalizeASCII(final String string) {
        final String normalize = Normalizer.normalize(string, Form.NFD);

        return Pattern.compile("\\p{InCombiningDiacriticalMarks}+")
                      .matcher(normalize)
                      .replaceAll("");
    } ...

I can grep the array for the id, but how can I delete the entire object where id == 88

Simply filter by the opposite predicate:

var data = $.grep(data, function(e){ 
     return e.id != id; 
});

Most of the solutions works but they have issue with jquery:

The issue is following code $(document).ready(function () { alert($("#includedContent").text()); } alerts nothing instead of alerting included content.

I write the below code, in my solution you can access to included content in $(document).ready function:

(The key is loading included content synchronously).

index.htm:

<html>
    <head>
        <script src="jquery.js"></script>

        <script>
            (function ($) {
                $.include = function (url) {
                    $.ajax({
                        url: url,
                        async: false,
                        success: function (result) {
                            document.write(result);
                        }
                    });
                };
            }(jQuery));
        </script>

        <script>
            $(document).ready(function () {
                alert($("#test").text());
            });
        </script>
    </head>

    <body>
        <script>$.include("include.inc");</script>
    </body>

</html>

include.inc:

<div id="test">
    There is no issue between this solution and jquery.

A timestamp is the elapsed time since Epoch time (01/01/1970), so basically we have to convert this time in days, and add the epoch time, to get a valid format for any Excel like spreadsheet software.

• From a timestamp in milliseconds (ex: 1488380243994)

  use this formula:

  =A1/1000/86400+25569
  

  with this formater:

  yyyy-mm-dd hh:mm:ss.000
  

• From a timestamp in seconds (ex: 1488380243)

  use this formula:

  =A1/86400+25569
  

  with this formater:

  yyyy-mm-dd hh:mm:ss
  

Where A1 is your column identifier. Given custom formaters allow to not loose precision in displayed data, but you can of course use any other date/time one that corresponds to your needs.

Merge Strategies

Explicit Merge: Creates a new merge commit. (This is what you will get if you used --no-ff.)

Fast Forward Merge: Forward rapidly, without creating a new commit:

Rebase: Establish a new base level:

Squash: Crush or squeeze (something) with force so that it becomes flat:

This worked for me:

Remove-Item $folderPath -Force  -Recurse -ErrorAction SilentlyContinue

Thus the folder is removed with all files in there and it is not producing error if folder path doesn't exists.

Based on this article, I have put together the following snippet that provides some very basic functionality:

<div id = "container"></div>
<script>
function setPDFHeight(){ 
        $("#pdfObject")[0].height = $("#pdfObject")[0].offsetHeight;   
}   
$('#container').append('<div align="center" style="width: 100%; height:100%; overflow: auto !important; -webkit-overflow-scrolling: touch !important;">\
      <object id="pdfObject" width="100%" height="1000000000000" align="center" data="content/lessons/12/t.pdf" type="application/pdf" onload="setPDFHeight()">You have no plugin installed</object></div>');  
</script>

Obviously it is far from perfect (given that it practically expands your page height to infinity), but it's the only viable workaround I've found so far.

Maven is a build tool. Along with Ant or Gradle are Javas tools for building.
If you are a newbie in Java though just build using your IDE since Maven has a steep learning curve.

This worked for me:

Add the follow line in app/build.gradle in dependencies section:

implementation "com.android.support:appcompat-v7:27.1.0"

or :27.1.1 in my case

This is my code .This works for me

componentDidMount(){
        axios.get('http://localhost:5000/supplier').then(
            response => {
                console.log(response)
                this.setState({suppliers:response.data.data})
            }
        )
        .catch(error => {
            console.log(error)
        })
        
    }

componentDidUpdate(){
        this.componentDidMount();
}

window.location.reload(); I think this thing is not good for react js

for date-time comparison, you can use valueOf function of the moment which provides milliseconds of the date-time, which is best for comparison:

let date1 = moment('01-02-2020','DD-MM-YYYY').valueOf()_x000D_
let date2 = moment('11-11-2012','DD-MM-YYYY').valueOf()_x000D_
_x000D_
//     alert((date1 > date2 ? 'date1' : 'date2') + " is greater..."  )_x000D_
_x000D_
if (date1 > date2) {_x000D_
   alert("date1 is greater..." )_x000D_
} else {_x000D_
   alert("date2 is greater..." )_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>

I've made something like the following code :)

It works only, when you have a second file named with _hover, for example, facebook.png and facebook_hover.png

$('#social').find('a').hover(function() {
    var target = $(this).find('img').attr('src');
    //console.log(target);
    var newTarg = target.replace('.png', '_hover.png');
    $(this).find('img').attr("src", newTarg);
}, function() {
    var target = $(this).find('img').attr('src');
    var newTarg = target.replace('_hover.png', '.png');
    $(this).find('img').attr("src", newTarg);
});

I have python2.7 installed via brew and the following solved my problem

brew install numpy

It installs python3, but it still works and sets it up for 2.7 as well.
