        <tr>      
            <td><%=allFestivals.get(i).getFestivalName()%></td>

    <% } %>

Better way is to use c:foreach see link jstl for each

ES6 (template literal) helper functions:

function rgba(r, g, b, a=1){

}

I have had problems getting radio buttons id's as well when the RadioButtons are dynamically generated. It does not seem to work if you try to manually set the ID's using RadioButton.setId(). What worked for me was to use View.getChildAt() and View.getParent() in order to iterate through the radio buttons and determine which one was checked. All you need is to first get the RadioGroup via findViewById(R.id.myRadioGroup) and then iterate through it's children. You'll know as you iterate through which button you are on, and you can simply use RadioButton.isChecked() to determine if that is the button that was checked.

I got solution after using below command:

git repack -a -f -d --window=250 --depth=250

If the project is maven placed it in src/main/resources, in the package phase it will copy it in ../WEB-INF/classes/hibernate.cfg.xml

I believe it is because cell.getCellStyle initially returns the default cell style which you then change.

Create styles like this and apply them to cells:

cellStyle = (XSSFCellStyle) cell.getSheet().getWorkbook().createCellStyle();

Although as the previous poster noted try and create styles and reuse them.

There is also some utility class in the XSSF library that will avoid the code I have provided and automatically try and reuse styles. Can't remember the class 0ff hand.

Simple for loop!

for (int start = 0, end = array.length - 1; start <= end; start++, end--) {
    int aux = array[start];
    array[start]=array[end];
    array[end]=aux;
}

Here's a variant that uses fancy indexing and has the actual values as an intermediate:

p31 = numpy.asarray(o31)
values = p31[p31<200]
za = len(values)

Have you tried using JavaScriptSerializer ? There's also DataContractJsonSerializer

How if you want to watch a property for a while and then to un-watch it?

Or to watch a library child component property?

You can use the "dynamic watcher":

this.$watch(
 'object.property', //what you want to watch
 (newVal, oldVal) => {
    //execute your code here
 }
)

The $watch returns an unwatch function which will stop watching if it is called.

var unwatch = vm.$watch('a', cb)
// later, teardown the watcher
unwatch()

Also you can use the deep option:

this.$watch(
'someObject', () => {
    //execute your code here
},
{ deep: true }
)

Please make sure to take a look to docs

I think you are confused about the difference between sourcing and executing a script.

Executing a script means creating a new process, and running the program. The program can be a shell script, or any other type of program. As it is a sub process, any environmental variables changed in the program will not affect the shell.

Sourcing a script can only be used with a bash script (if you are running bash). It effectively types the commands in as if you did them. This is useful as it lets a script change environmental variables in the shell.

Running a script is simple, you just type in the path to the script. . is the current directory. So ./script.sh will execute the file script.sh in the current directory. If the command is a single file (eg script.sh), it will check all the folders in the PATH variable to find the script. Note that the current directory isn't in PATH, so you can't execute a file script.sh in the current directory by running script.sh, you need to run ./script.sh (unless the current directory is in the PATH, eg you can run ls while in the /bin dir).

Sourcing a script doesn't use the PATH, and just searches for the path. Note that source isn't a program - otherwise it wouldn't be able to change environmental variables in the current shell. It is actually a bash built in command. Search /bin and /usr/bin - you won't find a source program there. So to source a file script.sh in the current directory, you just use source script.sh.

How does sudo interact with this? Well sudo takes a program, and executes it as root. Eg sudo ./script.sh executes script.sh in a sub process but running as root.

What does sudo source ./script.sh do however? Remember source isn't a program (rather a shell builtin)? Sudo expects a program name though, so it searches for a program named source. It doesn't find one, and so fails. It isn't possible to source a file running as root, without creating a new subprocess, as you cannot change the runner of a program (in this case, bash) after it has started.

I'm not sure what you actually wanted, but hopefully this will clear it up for you.

Here is a concrete example. Make the file script.sh in your current directory with the contents:

#!/bin/bash    
export NEW_VAR="hello"
whoami
echo "Some text"

Make it executable with chmod +x script.sh.

Now observe what happens with bash:

> ./script.sh
david
Some text
> echo $NEW_VAR

> sudo ./script.sh
root
Some text
> echo $NEW_VAR

> source script.sh
david
Some text
> echo $NEW_VAR
hello
> sudo source script.sh
sudo: source: command not found

To fit to the visible markers only, I've this method.

fitMapBounds() {
    // Get all visible Markers
    const visibleMarkers = [];
    this.map.eachLayer(function (layer) {
        if (layer instanceof L.Marker) {
            visibleMarkers.push(layer);
        }
    });

    // Ensure there's at least one visible Marker
    if (visibleMarkers.length > 0) {

        // Create bounds from first Marker then extend it with the rest
        const markersBounds = L.latLngBounds([visibleMarkers[0].getLatLng()]);
        visibleMarkers.forEach((marker) => {
            markersBounds.extend(marker.getLatLng());
        });

        // Fit the map with the visible markers bounds
        this.map.flyToBounds(markersBounds, {
            padding: L.point(36, 36), animate: true,
        });
    }
}

{{ data.0 }} should work.

Let's say you wrote data.obj django tries data.obj and data.obj(). If they don't work it tries data["obj"]. In your case data[0] can be written as {{ data.0 }}. But I recommend you to pull data[0] in the view and send it as separate variable.

I had the same issue, I resolved it using some javascript.

<script type="text/javascript">
 var theHeight = $("#PrimaryContent").height() + 100;
 $('#SecondaryContent').height(theHeight);
</script>

Maybe it is just my Java and C background showing, but I prefer CamelCase (CapCase) over punctuation in the name. My workgroup uses such names, probably to match the names of the app or service the repository contains.

You can return more than one value using list also. Check the code below

def newFn():    #your function
  result = []    #defining blank list which is to be return
  r1 = 'return1'    #first value
  r2 = 'return2'    #second value
  result.append(r1)    #adding first value in list
  result.append(r2)    #adding second value in list
  return result    #returning your list

ret_val1 = newFn()[1]    #you can get any desired result from it
print ret_val1    #print/manipulate your your result

Firequark is an extension to Firebug to aid the process of HTML Screen Scraping. Firequark automatically extracts css selector for a single or multiple html node(s) from a web page using Firebug (a web development plugin for Firefox). The css selector generated can be given as an input to html screen scrapers like Scrapi to extract information. Firequark is built to unleash the power of css selector for use of html screen scraping.

In addition to running it with mvn exec:java, you can also run it with mvn exec:exec

mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath your.package.MainClass"

The answers are outdated. You simply have to conda install pip and git. Then you can use pip normally:

1. Activate your conda environment source activate myenv

Balabaster's answer is correct if you want to remove all instances of the element. If you want to remove only the first one, you would do something like this:

int[] numbers = { 1, 3, 4, 9, 2, 4 };
int numToRemove = 4;
int firstFoundIndex = Array.IndexOf(numbers, numToRemove);
if (numbers >= 0)
{
    numbers = numbers.Take(firstFoundIndex).Concat(numbers.Skip(firstFoundIndex + 1)).ToArray();
}

This HTML + CSS solution worked for me:

  color: gray;_x000D_
}_x000D_
_x000D_
form select:invalid option:not(:first-child) {_x000D_
  color: black;_x000D_
}

<form>_x000D_
  <select required>_x000D_
    <option value="">Select Planet...</option>_x000D_
    <option value="earth">Earth</option>_x000D_
    <option value="pandora">Pandora</option>_x000D_

'O' stands for object.

#Loading a csv file as a dataframe
import pandas as pd 
train_df = pd.read_csv('train.csv')
col_name = 'Name of Employee'

#Checking the datatype of column name
train_df[col_name].dtype

#Instead try printing the same thing
print train_df[col_name].dtype

The first line returns: dtype('O')

The line with the print statement returns the following: object

It works the same way for axes: parse(text='70^o*N') will raise the o as a superscript (the *N is to make sure the N doesn't get raised too).

labelsX=parse(text=paste(abs(seq(-100, -50, 10)), "^o ", "*W", sep=""))
labelsY=parse(text=paste(seq(50,100,10), "^o ", "*N", sep=""))
plot(-100:-50, 50:100, type="n", xlab="", ylab="", axes=FALSE)
axis(1, seq(-100, -50, 10), labels=labelsX)
axis(2, seq(50, 100, 10), labels=labelsY)

Perhaps the question needs to be slightly more precise here about what is required because it can be read it two different ways. i.e.

1. How do I get the structure/definition for a table in mysql?
2. How do I get the name of the schema/database this table resides in?

Given the accepted answer, the OP clearly intended it to be interpreted the first way. For anybody reading the question the other way try

SELECT `table_schema` 
FROM `information_schema`.`tables` 
WHERE `table_name` = 'whatever';

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

describe table_name;

One possibility would be to just add the space into you character class, like acheong87 suggested, this depends on how strict you are on your pattern, because this would also allow a string starting with 5 spaces, or strings consisting only of spaces.

The other possibility is to define a pattern:

I will use \w this is in most regex flavours the same than [a-zA-Z0-9_] (in some it is Unicode based)

^\w+( \w+)*$

This will allow a series of at least one word and the words are divided by spaces.

^ Match the start of the string

\w+ Match a series of at least one word character

( \w+)* is a group that is repeated 0 or more times. In the group it expects a space followed by a series of at least one word character

$ matches the end of the string

This seems really difficult to solve without a DB lookup upon every token verification. The alternative I can think of is keeping a blacklist of invalidated tokens server-side; which should be updated on a database whenever a change happens to persist the changes across restarts, by making the server check the database upon restart to load the current blacklist.

But if you keep it in the server memory (a global variable of sorts) then it's not gonna be scalable across multiple servers if you are using more than one, so in that case you can keep it on a shared Redis cache, which should be set-up to persist the data somewhere (database? filesystem?) in case it has to be restarted, and every time a new server is spun up it has to subscribe to the Redis cache.

Alternative to a black-list, using the same solution, you can do it with a hash saved in redis per session as this other answer points out (not sure that would be more efficient with many users logging in though).

Does it sound awfully complicated? it does to me!

Disclaimer: I have not used Redis.

            String strFilePath = "Your path";
            try {
                 FileOutputStream fos = new FileOutputStream(strFilePath);
                 String strContent = "Write File using Java ";

                 fos.write(strContent.getBytes());
                 fos.close();
           }
          catch(FileNotFoundException ex)   {
                 System.out.println("FileNotFoundException : " + ex);
          }
         catch(IOException ioe)  {
                 System.out.println("IOException : " + ioe);
          }

Try this: Create a plain div without any style or content outside of the red div. Now you can use a loop over all styles of the plain div and assign then to your inner div to reset all styles.

Of course this doesn't work if someone assigns styles to all divs (i.e. without using a class. CSS would be div { ... }).

The usual solution for problems like this is to give your div a distinct class. That way, web designers of the sites can adjust the styling of your div to fit into the rest of the design.

Since IOS 9.0 use UIAlertController:

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
                                                           message:@"This is an alert."
                                                          preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
                                                  handler:^(UIAlertAction * action) {
                    //use alert.textFields[0].text
                                                       }];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault
                                                      handler:^(UIAlertAction * action) {
                                                          //cancel action
                                                      }];
[alert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
    // A block for configuring the text field prior to displaying the alert
}];
[alert addAction:defaultAction];
[alert addAction:cancelAction];
[self presentViewController:alert animated:YES completion:nil];

There can be one more approach. However it is not as efficient as the one already suggested in answers.

• Create a path vector for the node n1.

• Create a second path vector for the node n2.

• Path vector implying the set nodes from that one would traverse to reach the node in question.

• Compare both path vectors. The index where they mismatch, return the node at that index - 1. This would give the LCA.

Cons for this approach:

Need to traverse the tree twice for calculating the path vectors. Need addtional O(h) space to store path vectors.

However this is easy to implement and understand as well.

Code for calculating the path vector:

private boolean findPathVector (TreeNode treeNode, int key, int pathVector[], int index) {

        if (treeNode == null) {
            return false;
        }

        pathVector [index++] = treeNode.getKey ();

        if (treeNode.getKey () == key) {
            return true;
        }
        if (findPathVector (treeNode.getLeftChild (), key, pathVector, index) || 
            findPathVector (treeNode.getRightChild(), key, pathVector, index)) {

            return true;        
        }

        pathVector [--index] = 0;
        return false;       
    }

I use Apache HTTPClient to handle all the HTTP side of things.

I write XML SAX parsers for the XML content that parses the XML into your object model. I believe that Axis2 also exposes XML -> Model methods (Axis 1 hid this part, annoyingly). XML generators are trivially simple.

It doesn't take long to code, and is quite efficient, in my opinion.

Default behaviour of PowerShell is just to dump everything that falls out of a pipeline without being picked up by another pipeline element or being assigned to a variable (or redirected) into Out-Host. What Out-Host does is obviously host-dependent.

Just letting things fall out of the pipeline is not a substitute for Write-Host which exists for the sole reason of outputting text in the host application.

If you want output, then use the Write-* cmdlets. If you want return values from a function, then just dump the objects there without any cmdlet.

mapStateToProps receives the state and props and allows you to extract props from the state to pass to the component.

mapDispatchToProps receives dispatch and props and is meant for you to bind action creators to dispatch so when you execute the resulting function the action gets dispatched.

I find this only saves you from having to do dispatch(actionCreator()) within your component thus making it a bit easier to read.

I think you could do:

$('#google_translate_element').find('*').each(function(){
    $(this).unbind('click');
});

but it would cause a lot of overhead

$('#button1').click(function(){
$('#myform').prop('action', 'page1.php');
});

You can return a List instead of an array and things gets much simpler.

    public static List<File> listf(String directoryName) {
        File directory = new File(directoryName);

        List<File> resultList = new ArrayList<File>();

        // get all the files from a directory
        File[] fList = directory.listFiles();
        resultList.addAll(Arrays.asList(fList));
        for (File file : fList) {
            if (file.isFile()) {
                System.out.println(file.getAbsolutePath());
            } else if (file.isDirectory()) {
                resultList.addAll(listf(file.getAbsolutePath()));
            }
        }
        //System.out.println(fList);
        return resultList;
    } 

You can check if it can be converted to decimal. If yes, then its a number

from decimal import Decimal

def is_number(value):
    try:
        value = Decimal(value)
        return True
    except:
        return False

print is_number(None)   // False
print is_number(0)      // True
print is_number(2.3)    // True
print is_number('2.3')  // True (caveat!)

It's a little unclear whether you're asking for opinions, eg. "it's common to do xxx" or an actual rule, so I'm going to lean in the direction of rules.

The examples you cite seem based upon the examples in the spec for the nav element. Remember that the spec keeps getting tweaked and the rules are sometimes convoluted, so I'd venture many people might tend to just do what's given rather than interpret. You're showing two separate examples with different behavior, so there's only so much you can read into it. Do either of those sites also have the opposing sub/nav situation, and if so how do they handle it?

Most importantly, though, there's nothing in the spec saying either is the way to do it. One of the goals with HTML5 was to be very clear[this for comparison] about semantics, requirements, etc. so the omission is worth noting. As far as I can see, the examples are independent of each other and equally valid within their own context of layout requirements, etc.

Having the nav's source position be conditional is kind of silly(another red flag). Just pick a method and go with it.

This solution applies in some cases - if possible:

If the iframe content page uses a subdomain of the page containing the iframe, the cookie is no longer blocked.

I did not yet see this variation, which I personally like the best:

Given an array:

var someArray = ["some", "example", "array"];

You can loop over it without ever accessing the length property:

for (var i=0, item; item=someArray[i]; i++) {
  // item is "some", then "example", then "array"
  // i is the index of item in the array
  alert("someArray[" + i + "]: " + item);
}

See this JsFiddle demonstrating that: http://jsfiddle.net/prvzk/

This only works for arrays that are not sparse. Meaning that there actually is a value at each index in the array. However, I found that in practice I hardly ever use sparse arrays in JavaScript... In such cases it's usually a lot easier to use an object as a map/hashtable. If you do have a sparse array, and want to loop over 0 .. length-1, you need the for (var i=0; i<someArray.length; ++i) construct, but you still need an if inside the loop to check whether the element at the current index is actually defined.

Also, as CMS mentions in a comment below, you can only use this on arrays that don't contain any falsish values. The array of strings from the example works, but if you have empty strings, or numbers that are 0 or NaN, etc. the loop will break off prematurely. Again in practice this is hardly ever a problem for me, but it is something to keep in mind, which makes this a loop to think about before you use it... That may disqualify it for some people :)

What I like about this loop is:

• It's short to write
• No need to access (let alone cache) the length property
• The item to access is automatically defined within the loop body under the name you pick.
• Combines very naturally with array.push and array.splice to use arrays like lists/stacks

The reason this works is that the array specification mandates that when you read an item from an index >= the array's length, it will return undefined. When you write to such a location it will actually update the length.

For me, this construct most closely emulates the Java 5 syntax that I love:

for (String item : someArray) {
}

... with the added benefit of also knowing about the current index inside the loop

If you want to take a component class as a parameter (vs an instance), use React.ComponentClass:

function renderGreeting(Elem: React.ComponentClass<any>) {
    return <span>Hello, <Elem />!</span>;
}

You probably need quotes around those string fields, but, you should be using parameterized queries!

cmd.CommandText = "INSERT INTO Data ([Name],PhoneNo,Address) VALUES (@name, @phone, @address)";
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@name", txtName.Text);
cmd.Parameters.AddWithValue("@phone", txtPhone.Text);
cmd.Parameters.AddWithValue("@address", txtAddress.Text);
cmd.Connection = connection;

Incidentally, your original query could have been fixed like this (note the single quotes):

"VALUES ('" + txtName.Text + "','" + txtPhone.Text + "','" + txtAddress.Text + "');";

but this would have made it vulnerable to SQL Injection attacks since a user could type in

'; drop table users; -- 

into one of your textboxes. Or, more mundanely, poor Daniel O'Reilly would break your query every time.

for a ionic project

    var imgURI       = "";
    var imgBBDD      = ""; //sqllite for save into

    function takepicture() {
                var options = {
                    quality : 75,
                    destinationType : Camera.DestinationType.DATA_URL,
                    sourceType : Camera.PictureSourceType.CAMERA,
                    allowEdit : true,
                    encodingType: Camera.EncodingType.JPEG,
                    targetWidth: 300,
                    targetHeight: 300,
                    popoverOptions: CameraPopoverOptions,
                    saveToPhotoAlbum: false
                };

                $cordovaCamera.getPicture(options).then(function(imageData) {
                    imgURI = "data:image/jpeg;base64," + imageData;
                    imgBBDD = imageData;
                }, function(err) {
                    // An error occured. Show a message to the user
                });
            }

And now we put imgBBDD into SqlLite

     function saveImage = function (theId, theimage){
      var insertQuery = "INSERT INTO images(id, image) VALUES("+theId+", '"+theimage+"');"
      console.log('>>>>>>>');
      DDBB.SelectQuery(insertQuery)
                    .then( function(result) {
                        console.log("Image saved");
                    })
                    .catch( function(err) 
                     {
                        deferred.resolve(err);
                        return cb(err);
                    });
    }

A server side (php)

        $request = file_get_contents("php://input"); // gets the raw data
        $dades = json_decode($request,true); // true for return as array


    if($dades==""){
            $array = array();
            $array['error'] = -1;
            $array['descError'] = "Error when get the file";
            $array['logError'] = '';
            echo json_encode($array);
            exit;
        }
        //send the image again to the client
        header('Content-Type: image/jpeg');
        echo '';

The answer here worked better for me as it isolates the search on the hashtag, not just returning results that contain the search string. In the answer above you would still need to parse the JSON response to see if the entities.hashtags array is not empty.

To do this, I think you should probably have an additional "ORDER" table which defines the mapping of IDs to order (effectively doing what your response to your own question said), which you can then use as an additional column on your select which you can then sort on.

In that way, you explicitly describe the ordering you desire in the database, where it should be.

Single command without ps variables when using JSON as body {lastName:"doe"} for POST api call:

Invoke-WebRequest -Headers @{"Authorization" = "Bearer N-1234ulmMGhsDsCAEAzmo1tChSsq323sIkk4Zq9"} `
                  -Method POST `
                  -Body (@{"lastName"="doe";}|ConvertTo-Json) `
                  -Uri https://api.dummy.com/getUsers `
                  -ContentType application/json

Try This:

var info = document.getElementById("area1").value; // Javascript
var info = $("#area1").val(); // jQuery

I'm successfully using the following to update options dynamically:

$control.select2('destroy').empty().select2({data: [{id: 1, text: 'new text'}]});

The short answer is += can be translated as "add whatever is to the right of the += to the variable on the left of the +=".

Ex. If you have a = 10 then a += 5 would be: a = a + 5

So, "a" now equal to 15.

//catch volume update
var volEvents = "change,input";
var volEventsArr = volEvents.split(",");
for(var i = 0;i<volknob.length;i++) {
    for(var k=0;k<volEventsArr.length;k++) {
    volknob[i].addEventListener(volEventsArr[k], function() {
        var cfa = document.getElementsByClassName('watch_televised');
        for (var j = 0; j<cfa.length; j++) {
            cfa[j].volume = this.value / 100;
        }
    });
}
}

Here is the closest you can get:

ArrayList<String> list = new ArrayList(Arrays.asList("Ryan", "Julie", "Bob"));

You can go even simpler with:

List<String> list = Arrays.asList("Ryan", "Julie", "Bob")

Looking at the source for Arrays.asList, it constructs an ArrayList, but by default is cast to List. So you could do this (but not reliably for new JDKs):

ArrayList<String> list = (ArrayList<String>)Arrays.asList("Ryan", "Julie", "Bob")

var methods = [];
for (var m in obj) {
    if (typeof obj[m] == "function") {
        methods.push(m);
    }
}
alert(methods.join(","));

This way, you will get all methods that you can call on obj. This includes the methods that it "inherits" from its prototype (like getMethods() in java). If you only want to see those methods defined directly by obj you can check with hasOwnProperty:

var methods = [];
for (var m in obj) {        
    if (typeof obj[m] == "function" && obj.hasOwnProperty(m)) {
        methods.push(m);
    }
}
alert(methods.join(","));

You can use dangerouslySetInnerHTML to do this:

import React from 'react';
function iframe() {
    return {
        __html: '<iframe src="./Folder/File.html" width="540" height="450"></iframe>'
    }
}


export default function Exercises() {
    return (
        <div>
            <div dangerouslySetInnerHTML={iframe()} />
        </div>)
}

HTML files must be in the public folder

If you're registering a domain and the termination (ex .com) it is not IDN, as Aaron Hathaway said: Hostnames are composed of series of labels concatenated with dots, as are all domain names. For example, en.wikipedia.org is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname (including the delimiting dots but not a trailing dot) has a maximum of 253 ASCII characters.

The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters a through z (in a case-insensitive manner), the digits 0 through 9, and the hyphen -. The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.

Later, Spain with it's .es, .com.es, .org.es, .nom,es, .gob.es and .edu.es introduced IDN tlds, if your tld is one of .es or any other that supports it, any character can be used, but you can't combine alphabets like Latin, Greek or Cyril in one hostname, and that it respects the things that can't go at the start or at the end.

If you're using non-registered tlds, just for local networking, like with local DNS or with hosts files, you can treat them all as IDN.

Keep in mind some programs could not work well, especially old, outdated and unpopular ones.

Here's a clean solution:

private byte[] downloadUrl(URL toDownload) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

    try {
        byte[] chunk = new byte[4096];
        int bytesRead;
        InputStream stream = toDownload.openStream();

        while ((bytesRead = stream.read(chunk)) > 0) {
            outputStream.write(chunk, 0, bytesRead);
        }

    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }

    return outputStream.toByteArray();
}

Might be a little late, but the beta POI now supports xlsx.

Depends on your requirment, but the most effective way to create is:

 Product obj = new Product
            {
                ID = 21,
                Price = 200,
                Category = "XY",
                Name = "SKR",
            };

After spending hours, I found that I missed 's' letter in table name

It was [Table("Employee")] instead of [Table("Employees")]

Don't try to read all the monad tutorials with funny metaphors. They will just get you mixed up even worse.

Hello please note like real work.

Children can not have two mother

So in java, subclass can not have two parent class.

If you can pick a reasonable maximum line length, you can seek to nearly the end of the file before you start reading.

myfile.seek(-max_line_length, os.SEEK_END)
line = myfile.readlines()[-1]

As for extension methods, extension methods themselves are static; but they are invoked as if they are instance methods. Since a static class is not instantiable, you would never have an instance of the class to invoke an extension method from. For this reason the compiler does not allow extension methods to be defined for static classes.

Mr. Obnoxious wrote: "As any advanced .NET developer knows, new T() is slow because it generates a call to System.Activator which uses reflection to get the default constructor before calling it".

New() is compiled to the IL "newobj" instruction if the type is known at compile time. Newobj takes a constructor for direct invocation. Calls to System.Activator.CreateInstance() compile to the IL "call" instruction to invoke System.Activator.CreateInstance(). New() when used against generic types will result in a call to System.Activator.CreateInstance(). The post by Mr. Obnoxious was unclear on this point... and well, obnoxious.

This code:

System.Collections.ArrayList _al = new System.Collections.ArrayList();
System.Collections.ArrayList _al2 = (System.Collections.ArrayList)System.Activator.CreateInstance(typeof(System.Collections.ArrayList));

produces this IL:

  .locals init ([0] class [mscorlib]System.Collections.ArrayList _al,
           [1] class [mscorlib]System.Collections.ArrayList _al2)
  IL_0001:  newobj     instance void [mscorlib]System.Collections.ArrayList::.ctor()
  IL_0006:  stloc.0
  IL_0007:  ldtoken    [mscorlib]System.Collections.ArrayList
  IL_000c:  call       class [mscorlib]System.Type [mscorlib]System.Type::GetTypeFromHandle(valuetype [mscorlib]System.RuntimeTypeHandle)
  IL_0011:  call       object [mscorlib]System.Activator::CreateInstance(class [mscorlib]System.Type)

There are two types of drop down lists available (I am not sure since which version).

ActiveX Drop Down
You can set the column widths, so your hidden column can be set to 0.

Form Drop Down
You could set the drop down range to a hidden sheet and reference the cell adjacent to the selected item. This would also work with the ActiveX type control.

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

Here is an example that should give you some idea..

=IIF(First(Fields!Gender.Value,"vw_BrgyClearanceNew")="Female" and 
(First(Fields!CivilStatus.Value,"vw_BrgyClearanceNew")="Married"),false,true)

I think you have to identify the datasource name or the table name where your data is coming from.

 private string GetClientIpaddress()
    {
        string ipAddress = string.Empty;
        ipAddress = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
        if (ipAddress == "" || ipAddress == null)
        {
            ipAddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
            return ipAddress;
        }
        else
        {
            return ipAddress;
        }
    }

I'm not fully sure that this is what you're looking for, but if your question is how to read an integer using <stdio.h>, then the proper syntax is

int myInt;
scanf("%d", &myInt);

You'll need to do a lot of error-handling to ensure that this works correctly, of course, but this should be a good start. In particular, you'll need to handle the cases where

1. The stdin file is closed or broken, so you get nothing at all.
2. The user enters something invalid.

To check for this, you can capture the return code from scanf like this:

int result = scanf("%d", &myInt);

If stdin encounters an error while reading, result will be EOF, and you can check for errors like this:

int myInt;
int result = scanf("%d", &myInt);

if (result == EOF) {
    /* ... you're not going to get any input ... */
}

If, on the other hand, the user enters something invalid, like a garbage text string, then you need to read characters out of stdin until you consume all the offending input. You can do this as follows, using the fact that scanf returns 0 if nothing was read:

int myInt;
int result = scanf("%d", &myInt);

if (result == EOF) {
    /* ... you're not going to get any input ... */
}
if (result == 0) {
    while (fgetc(stdin) != '\n') // Read until a newline is found
        ;
}

Hope this helps!

EDIT: In response to the more detailed question, here's a more appropriate answer. :-)

The problem with this code is that when you write

printf("got the number: %d", scanf("%d", &x));

This is printing the return code from scanf, which is EOF on a stream error, 0 if nothing was read, and 1 otherwise. This means that, in particular, if you enter an integer, this will always print 1 because you're printing the status code from scanf, not the number you read.

To fix this, change this to

int x;
scanf("%d", &x);
/* ... error checking as above ... */
printf("got the number: %d", x);

Hope this helps!

In Map one can Iteration over keys and/or values and/or both (e.g., entrySet) depends on one's interested in_ Like:

1. Iterate through the keys -> keySet() of the map:

    Map<String, Object> map = ...;
   
    for (String key : map.keySet()) {
        //your Business logic...
    }
   

2. Iterate through the values -> values() of the map:

    for (Object value : map.values()) {
        //your Business logic...
    }
   

3. Iterate through the both -> entrySet() of the map:

    for (Map.Entry<String, Object> entry : map.entrySet()) {
        String key = entry.getKey();
        Object value = entry.getValue();
        //your Business logic...
    }
   

Moreover, there are 3 different ways to iterate through a HashMap. They are as below:

//1.
for (Map.Entry entry : hm.entrySet()) {
    System.out.print("key,val: ");
    System.out.println(entry.getKey() + "," + entry.getValue());
}

//2.
Iterator iter = hm.keySet().iterator();
while(iter.hasNext()) {
    Integer key = (Integer)iter.next();
    String val = (String)hm.get(key);
    System.out.println("key,val: " + key + "," + val);
}

//3.
Iterator it = hm.entrySet().iterator();
while (it.hasNext()) {
    Map.Entry entry = (Map.Entry) it.next();
    Integer key = (Integer)entry.getKey();
    String val = (String)entry.getValue();
    System.out.println("key,val: " + key + "," + val);
}

if you are using tomcat you may try this

<servlet-mapping>

    <http-method>POST</http-method>

</servlet-mapping>

in addition to <servlet-name> and <url-mapping>

As Herman pointed out, you can get the index and element from each iteration.

{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}

Working example:

package main

import (
    "html/template"
    "os"
)

type EntetiesClass struct {
    Name string
    Value int32
}

// In the template, we use rangeStruct to turn our struct values
// into a slice we can iterate over
var htmlTemplate = `{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}`

func main() {
    data := map[string][]EntetiesClass{
        "Yoga": {{"Yoga", 15}, {"Yoga", 51}},
        "Pilates": {{"Pilates", 3}, {"Pilates", 6}, {"Pilates", 9}},
    }

    t := template.New("t")
    t, err := t.Parse(htmlTemplate)
    if err != nil {
        panic(err)
    }

    err = t.Execute(os.Stdout, data)
    if err != nil {
        panic(err)
    }

}

Output:

Pilates
3
6
9

Yoga
15
51

This is pretty easy using the JavaScript selenium-webdriver client:

First, make sure you have a WebDriver server running. For example, download ChromeDriver, then run chromedriver --port=9515.

Second, create the driver like this:

var driver = new webdriver.Builder()
   .withCapabilities(webdriver.Capabilities.chrome())
   .usingServer('http://localhost:9515')  // <- this
   .build();

Here's a complete example:

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder()
   .withCapabilities(webdriver.Capabilities.chrome())
   .usingServer('http://localhost:9515')
   .build();

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.getTitle().then(function(title) {
   console.log(title);
 });

driver.quit();

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.

It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.

In our case, nothing was added in the Windows Event Logs except logs that the problematic service has been started and then stopped.

It turns out that the service's CONFIG file was invalid. Correcting the invalid CONFIG file fixed the issue.

You can use the Enum::valueOf() function as suggested by Gareth Davis & Brad Mace above, but make sure you handle the IllegalArgumentException that would be thrown if the string used is not present in the enum.

You may also want to use sbt about that (copying Mark Harrah's comment):

The about command was added recently to try to succinctly print the most relevant information, including the sbt version.

from table_A a
inner join table_B b on a.id=b.id

When root permissions are required

When root permissions are required for the destination file, use |sudo tee instead of >:

cat << 'EOF' |sudo tee /tmp/yourprotectedfilehere
The variable $FOO will *not* be interpreted.
EOF

cat << "EOF" |sudo tee /tmp/yourprotectedfilehere
The variable $FOO *will* be interpreted.
EOF

Paramiko is so slow. Use subprocess and shell, here is an example:

remote_file_name = "filename"
remotedir = "/remote/dir"
localpath = "/local/file/dir"
    ftp_cmd_p = """
    #!/bin/sh
    lftp -u username,password sftp://ip:port <<EOF
    cd {remotedir}
    lcd {localpath}
    get {filename}
    EOF
    """
subprocess.call(ftp_cmd_p.format(remotedir=remotedir,
                                 localpath=localpath,
                                 filename=remote_file_name 
                                 ), 
                shell=True, stdout=sys.stdout, stderr=sys.stderr)

put these in values/colors.xml

<resources>
    <color name="light_font">#FBFBFB</color>
    <color name="grey_font">#ff9e9e9e</color>
    <color name="text_shadow">#7F000000</color>
    <color name="text_shadow_white">#FFFFFF</color>
</resources>

Then in your layout xml here are some example TextView's

Example of Floating text on Light with Dark shadow

<TextView android:id="@+id/txt_example1"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:textSize="14sp"
                  android:textStyle="bold"
                  android:textColor="@color/light_font"
                  android:shadowColor="@color/text_shadow"
                  android:shadowDx="1"
                  android:shadowDy="1"
                  android:shadowRadius="2" />

Example of Etched text on Light with Dark shadow

<TextView android:id="@+id/txt_example2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="14sp"
                android:textStyle="bold"
                android:textColor="@color/light_font"
                android:shadowColor="@color/text_shadow"
                android:shadowDx="-1"
                android:shadowDy="-1"
                android:shadowRadius="1" />

Example of Crisp text on Light with Dark shadow

<TextView android:id="@+id/txt_example3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="14sp"
                android:textStyle="bold"
                android:textColor="@color/grey_font"
                android:shadowColor="@color/text_shadow_white"
                android:shadowDx="-2"
                android:shadowDy="-2"
                android:shadowRadius="1" />

Notice the positive and negative values... I suggest to play around with the colors/values yourself but ultimately you can adjust these settings to get the effect your looking for.

Protected members can be accessed from derived classes. Private ones can't.

class Base {

private: 
  int MyPrivateInt;
protected: 
  int MyProtectedInt;
public:
  int MyPublicInt;
};

class Derived : Base
{
public:
  int foo1()  { return MyPrivateInt;} // Won't compile!
  int foo2()  { return MyProtectedInt;} // OK  
  int foo3()  { return MyPublicInt;} // OK
};??

class Unrelated 
{
private:
  Base B;
public:
  int foo1()  { return B.MyPrivateInt;} // Won't compile!
  int foo2()  { return B.MyProtectedInt;} // Won't compile
  int foo3()  { return B.MyPublicInt;} // OK
};

In terms of "best practice", it depends. If there's even a faint possibility that someone might want to derive a new class from your existing one and need access to internal members, make them Protected, not Private. If they're private, your class may become difficult to inherit from easily.

The problem you're running into is that you're trying to replace an entire row object. That is not allowed by the DataTable API. Instead you have to update the values in the columns of a row object. Or add a new row to the collection.

To update the column of a particular row you can access it by name or index. For instance you could write the following code to update the column "Foo" to be the value strVerse

dtResult.Rows(i)("Foo") = strVerse

The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.

To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.

Could I write "table" or any other html tag instead of "/" ?

Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.

Here a few links:

• XSL templates
• XPath
• A good book about XML - Beginning XML

int val = '1' - 48;

You can use RIGHT :

 select RIGHT(123.45,2) return => 45

Let

var set = new HashSet<string> { ".mp3", ".jpg" };

Then

Directory.GetFiles(path, "*.*", SearchOption.AllDirectories)
         .Where(f => set.Contains(
             new FileInfo(f).Extension,
             StringComparer.OrdinalIgnoreCase));

or

from file in Directory.GetFiles(path, "*.*", SearchOption.AllDirectories)
from ext in set
where String.Equals(ext, new FileInfo(file).Extension, StringComparison.OrdinalIgnoreCase)
select file;

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

In case that you are dockerizing your python application, your Dockerfile needs to have something like:

FROM python:3.7-alpine

RUN apk add --update alpine-sdk && apk add libffi-dev openssl-dev

RUN pip install cryptography

Based on @konrad-garus answer, but using data, since I believe class should be used mostly for styling.

if (!el.data("bound")) {
  el.data("bound", true);
  el.on("event", function(e) { ... });
}

You can do "redundant styling" and that should fix the issue. You use the same styling you have on the but add it to a that is within the .

Example:

<td width="110" align="center" valign="top" style="color:#000000;">
    <a href="https://example.com" target="_blank"
       style="color:#000000; text-decoration:none;"><span style="color:#000000; text-decoration:none;">BOOK NOW</span></a>
</td>

The following set of code is working without any problems for me

Gradle

// Retrofit
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.12.1'

RetrofitClient

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(logging)
        .build();

retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build();

One can also verify the results by going into Profiler Tab at bottom of Android Studio, then clicking + sign to Start A New Session, and then select the desired spike in "Network". There you can get everything, but it is cumbersome and slow. Please see image below.

this works for me try it.

I've occasionally thought that it might serve a purpose to add a layer of security by obscuring the back-end interpreter through a remapping of .php or whatever to .aspx or whatever so that any potential hacker would be sent down the wrong path, at least for a while. I never bothered to try it and I don't do a lot of webserver work any more so I'm unlikely to.

However, I'd be interested in the perspective of an experienced server admin on that notion.

And if you need to extract several properties from each object, then

let newArr = _.map(arr, o => _.pick(o, ['name', 'surname', 'rate']));

Use sed's substitution: sed 's/"//g'

s/X/Y/ replaces X with Y.

g means all occurrences should be replaced, not just the first one.

jQuery.fn.make_me_red = function() {
    alert($(this).attr('id'));
    $(this).siblings("#hello").toggle();
}
$("#user_button").click(function(){
    //$(this).siblings(".hello").make_me_red(); 
    $(this).make_me_red(); 
    $(this).addClass("active");
});
?

Function declaration and callback in jQuery.

I've found that replacing the first part of the URL with IP address numbers instead of words worked for me.

For example use:

http://111.11.11.111/svn/Directory

instead of:

http://www.url.com/svn/Directory

This code will do that

<?php
$string = 'abc-123-xyz-789';
$output = explode("-",$string);
echo $output[count($output)-1];
?>

I have similar trouble in test config, because of using AOP. I added this line of code in spring-config.xml

<aop:config proxy-target-class="true"/>

And it works !

The answer to my own question is, I think, to use tomcat7.exe:

cd $CATALINA_HOME
.\bin\service.bat install tomcat
.\bin\tomcat7.exe //US//tomcat7 --JvmMs=512 --JvmMx=1024 --JvmSs=1024

Also, you can launch the UI tool mentioned by BalusC without the system tray or using the installer with tomcat7w.exe

.\bin\tomcat7w.exe //ES//tomcat

An additional note to this:

Setting the --JvmXX parameters (through the UI tool or the command line) may not be enough. You may also need to specify the JVM memory values explicitly. From the command line it may look like this:

bin\tomcat7w.exe //US//tomcat7 --JavaOptions=-Xmx=1024;-Xms=512;..

Be careful not to override the other JavaOption values. You can try updating bin\service.bat or use the UI tool and append the java options (separate each value with a new line).

This worked for me:

$this->db->where('RecordDate >=', '2018-08-17 00:00:00');
$this->db->where('RecordDate <=', '2018-10-04 05:32:56');

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

By using the List property.

ListBox1.AddItem "foo"
ListBox1.List(ListBox1.ListCount - 1, 1) = "bar"

The preferred method is actually:

@System.Web.Configuration.WebConfigurationManager.AppSettings["myKey"]

It also doesn't need a reference to the ConfigurationManager assembly, it's already in System.Web.

It is the underlying urllib3 library that does the retrying. To set a different maximum retry count, use alternative transport adapters:

from requests.adapters import HTTPAdapter

s = requests.Session()
s.mount('http://stackoverflow.com', HTTPAdapter(max_retries=5))

The max_retries argument takes an integer or a Retry() object; the latter gives you fine-grained control over what kinds of failures are retried (an integer value is turned into a Retry() instance which only handles connection failures; errors after a connection is made are by default not handled as these could lead to side-effects).

Old answer, predating the release of requests 1.2.1:

The requests library doesn't really make this configurable, nor does it intend to (see this pull request). Currently (requests 1.1), the retries count is set to 0. If you really want to set it to a higher value, you'll have to set this globally:

import requests

requests.adapters.DEFAULT_RETRIES = 5

This constant is not documented; use it at your own peril as future releases could change how this is handled.

Update: and this did change; in version 1.2.1 the option to set the max_retries parameter on the HTTPAdapter() class was added, so that now you have to use alternative transport adapters, see above. The monkey-patch approach no longer works, unless you also patch the HTTPAdapter.__init__() defaults (very much not recommended).

You can set position of image is align center horizontal by this

I ran into this problem with a particular webpage I was maintaining. No matter what settings I changed, it kept going back to IE8 compatibility mode.

It turned out X-UA-Compatible was set in the metadata in the head:

<meta http-equiv="X-UA-Compatible" content="IE=8" >

As I later discovered, and at least in Internet Explorer 11, you can see where it gets its "document mode" from, by going into developer tools (F12), then selecting the tab "Emulation", and checking the text below the drop down "Document mode".

Since we only support IE11 and higher, and Microsoft says document modes are deprecated, I just threw the whole thing out. That solved it.

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

i am ubuntu 18 with sublime text 3.2

[::]:80 is a ipv6 address.

This error can be caused if you have a nginx configuration that is listening on port 80 and also on port [::]:80.

I had the following in my default sites-available file:

listen 80;
listen [::]:80 default_server;

You can fix this by adding ipv6only=on to the [::]:80 like this:

listen 80;
listen [::]:80 ipv6only=on default_server;

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.

Are you looking to play around with Reflection or are you looking to build a production piece of software? I would question why you're using reflection to set a property.

Source: PHP Function that Generates Random Characters

This PHP function worked for me:

function cvf_ps_generate_random_code($length=10) {

   $string = '';
   // You can define your own characters here.
   $characters = "23456789ABCDEFHJKLMNPRTVWXYZabcdefghijklmnopqrstuvwxyz";

   for ($p = 0; $p < $length; $p++) {
       $string .= $characters[mt_rand(0, strlen($characters)-1)];
   }

   return $string;

}

Usage:

echo cvf_ps_generate_random_code(5);

I wrote a quick simple app recent that handle the management of various version of node and npm. It allows you to choose different version of node and npm to download and select which version to use. Check it out and see if it's something that's useful.

If you want to set the whole new column to an initial base value (e.g. None), you can do this: df1['e'] = None

This actually would assign "object" type to the cell. So later you're free to put complex data types, like list, into individual cells.

This is simply what to do:

datetime.datetime.now() - datetime.timedelta(minutes = 15)

timedeltas are specifically designed to allow you to subtract or add deltas (differences) to datetimes.

function invertArray(array,arrayWidth,arrayHeight) {
  var newArray = [];
  for (x=0;x<arrayWidth;x++) {
    newArray[x] = [];
    for (y=0;y<arrayHeight;y++) {
        newArray[x][y] = array[y][x];
    }
  }
  return newArray;
}

There is also the MATLAB Engine for Python by MathWorks itself. If you have MATLAB, this might be worth considering (I haven't tried it myself but it has a lot more functionality than just reading MATLAB files). However, I don't know if it is allowed to distribute it to other users (it is probably not a problem if those persons have MATLAB. Otherwise, maybe NumPy is the right way to go?).

Also, if you want to do all the basics yourself, MathWorks provides (if the link changes, try to google for matfile_format.pdf or its title MAT-FILE Format) a detailed documentation on the structure of the file format. It's not as complicated as I personally thought, but obviously, this is not the easiest way to go. It also depends on how many features of the .mat-files you want to support.

I've written a "small" (about 700 lines) Python script which can read some basic .mat-files. I'm neither a Python expert nor a beginner and it took me about two days to write it (using the MathWorks documentation linked above). I've learned a lot of new stuff and it was quite fun (most of the time). As I've written the Python script at work, I'm afraid I cannot publish it... But I can give some advice here:

• First read the documentation.
• Use a hex editor (such as HxD) and look into a reference .mat-file you want to parse.
• Try to figure out the meaning of each byte by saving the bytes to a .txt file and annotate each line.
• Use classes to save each data element (such as miCOMPRESSED, miMATRIX, mxDOUBLE, or miINT32)
• The .mat-files' structure is optimal for saving the data elements in a tree data structure; each node has one class and subnodes

public void mainWork() {
    new Handler(Looper.getMainLooper()).post(new Runnable() {
        @Override
        public void run() {
            //Add Your Code Here
        }
    });
}

This can also work in a service class with no issue.

1. Open design view
2. Right click to textArea
3. open surround with option
4. select "...JScrollPane".

I did the following steps to resolve the issue. On the branch which was giving me the error:

1. git pull origin [branch-name]<current branch>
2. After pulling, got some merge issues, solved them, pushed the changes to the same branch.
3. Created the Pull request with the pushed branch... tada, My changes were reflecting, all of them.

Yes, gzip will let you do this. If you simply run gzip > foo.gz, it will compress STDIN to the file foo.gz. You can also pipe data into it, like some_command | gzip > foo.gz.

The more powerful (and 100% fluid) Bootstrap 3 grid now comes in 3 sizes. Tiny (for smartphones .col-), Small (for tablets .col-sm-) and Large (for laptops/desktops .col-lg-*). The 3 grid sizes enable you to control grid behavior on different devices (desktop, tablet, smartphone, etc..).

Unlike 2.x, Bootstrap 3 does not provide a fixed (pixel-based) grid. While a fixed-width layout can still be acheived using a simple custom wrapper, there is now only one percentage-based (fluid) grid. The .container and .row classes are now fluid by default, so don't use .row-fluid or .container-fluid anymore in your 3.x markup.

The answer to your question is that the newer SQLite 3 has improved performance, use that.

This answer Why is SQLAlchemy insert with sqlite 25 times slower than using sqlite3 directly? by SqlAlchemy Orm Author has 100k inserts in 0.5 sec, and I have seen similar results with python-sqlite and SqlAlchemy. Which leads me to believe that performance has improved with SQLite 3.

You can do this without needing external libraries also by doing the following:

class Program
{
    static void Main(string[] args)
    {
        Bootstrapper bs = new Bootstrapper();
        var getListTask = bs.GetList(); // returns the Task<List<TvChannel>>

        Task.WaitAll(getListTask); // block while the task completes

        var list = getListTask.Result;
    }
}

a = ['1', '1', '1', '1', '1', '1', '2', '2', '2', '2', '7', '7', '7', '10', '10']
print a.count("1")

It's probably optimized heavily at the C level.

Edit: I randomly generated a large list.

In [8]: len(a)
Out[8]: 6339347

In [9]: %timeit a.count("1")
10 loops, best of 3: 86.4 ms per loop

Edit edit: This could be done with collections.Counter

a = Counter(your_list)
print a['1']

Using the same list in my last timing example

In [17]: %timeit Counter(a)['1']
1 loops, best of 3: 1.52 s per loop

My timing is simplistic and conditional on many different factors, but it gives you a good clue as to performance.

Here is some profiling

        <Route path='/complete-profiles' component={Profiles} />
        <Link to='/complete-profiles'>
          <div>Completed Profiles</div>
        </Link>
      </Router>

If you want to drop a table you should execute the following query in a single step

SET FOREIGN_KEY_CHECKS=0; DROP TABLE table_name;

user infomation is stored in /etc/passwd, so you can use "grep 'usename' /etc/passwd" to check if the username exist. meanwhile you can use "id" shell command, it will print the user id and group id, if the user does not exist, it will print "no such user" message.

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

As others have pointed out, the accepted answer does not return both x86 and x64 installs. Below is my solution for that. It creates a StringBuilder, appends the registry values to it (with formatting), and writes its output to a text file:

const string FORMAT = "{0,-100} {1,-20} {2,-30} {3,-8}\n";

private void LogInstalledSoftware()
{
    var line = string.Format(FORMAT, "DisplayName", "Version", "Publisher", "InstallDate");
    line += string.Format(FORMAT, "-----------", "-------", "---------", "-----------");
    var sb = new StringBuilder(line, 100000);
    ReadRegistryUninstall(ref sb, RegistryView.Registry32);
    sb.Append($"\n[64 bit section]\n\n{line}");
    ReadRegistryUninstall(ref sb, RegistryView.Registry64);
    File.WriteAllText(@"c:\temp\log.txt", sb.ToString());
}

   private static void ReadRegistryUninstall(ref StringBuilder sb, RegistryView view)
    {
        const string REGISTRY_KEY = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
        using var baseKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, view);
        using var subKey = baseKey.OpenSubKey(REGISTRY_KEY);
        foreach (string subkey_name in subKey.GetSubKeyNames())
        {
            using RegistryKey key = subKey.OpenSubKey(subkey_name);
            if (!string.IsNullOrEmpty(key.GetValue("DisplayName") as string))
            {
                var line = string.Format(FORMAT,
                    key.GetValue("DisplayName"),
                    key.GetValue("DisplayVersion"),
                    key.GetValue("Publisher"),
                    key.GetValue("InstallDate"));
                sb.Append(line);
            }
            key.Close();
        }
        subKey.Close();
        baseKey.Close();
    }

Here are different method of doing this. And i found your code is even working fine.

Your code: http://jsfiddle.net/NKC2j/

Jquery toggle class demo: http://jsfiddle.net/NKC2j/2/

Jquery fade toggle: http://jsfiddle.net/NKC2j/3/

And you can do this with CSS as answered by Sandeep

Usually this kind of error comes when you do DateTime conversion or parsing. Check the calendar setting in the server where the application is hosted, mainly the time zone and short date format, and ensure it's set to the right time zone for the location. Hope this would resolve the issue.

textLabel.text = @"\nAAAAA\nBBBBB\nCCCCC";
textLabel.numberOfLines = 3; \\As you want - AAAAA\nBBBBB\nCCCCC
textLabel.lineBreakMode = UILineBreakModeWordWrap;
NSLog(@"The textLabel text is - %@",textLabel.text);

Your example shows "instance variables", not really class variables.

Look in hi_obj.__class__.__dict__.items() for the class variables, along with other other class members like member functions and the containing module.

class Hi( object ):
    class_var = ( 23, 'skidoo' ) # class variable
    def __init__( self ):
        self.ii = "foo" # instance variable
        self.jj = "bar"

Class variables are shared by all instances of the class.

It is a public final field for the array type. You can refer to the document below:

http://java.sun.com/docs/books/jls/third_edition/html/arrays.html#10.7

You said :

Maybe my data.frame is not in a good format?

Yes this is true. Your data is in the wide format You need to put it in the long format. Generally speaking, long format is better for variables comparison.

Using reshape2 for example , you do this using melt:

dat.m <- melt(dat,id.vars = "Rank") ## just melt(dat) should work

Then you get your barplot:

ggplot(dat.m, aes(x = Rank, y = value,fill=variable)) +
    geom_bar(stat='identity')

But using lattice and barchart smart formula notation , you don't need to reshape your data , just do this:

barchart(F1+F2+F3~Rank,data=dat)

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

A lot of times, this will be because the string you're trying to parse is blank:

>>> import json
>>> x = json.loads("")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/__init__.py", line 348, in loads
    return _default_decoder.decode(s)
  File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

You can remedy by checking whether json_string is empty beforehand:

import json

if json_string:
    x = json.loads(json_string)
else:
    # Your code/logic here 
    x = {}

That is exactly how you do it in C#, but the feature was first added in .NET 4.0

I found a solution that works on jQuery 3.4.1 slim

After un-minifying, add {passive: true} to the addEventListener function on line 1567 like so:

t.addEventListener(p, a, {passive: true}))

Nothing breaks and lighthouse audits don't complain about the listeners.

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

Python has more than one way to do strings. The following string syntax would allow you to use double quotes:

'''what"ever'''

This can trim several characters at a time:

function trimChars (str, c) {
  var re = new RegExp("^[" + c + "]+|[" + c + "]+$", "g");
  return str.replace(re,"");
}

var x = "|f|oo||"; 
x =  trimChars(x, '|'); // f|oo

var y = "..++|f|oo||++..";
y = trimChars(y, '|.+'); // f|oo

var z = "\\f|oo\\"; // \f|oo\

// For backslash, remember to double-escape:
z = trimChars(z, "\\\\"); // f|oo

For use in your own script and if you don't mind changing the prototype, this can be a convenient "hack":

String.prototype.trimChars = function (c) {
  var re = new RegExp("^[" + c + "]+|[" + c + "]+$", "g");
  return this.replace(re,"");
}

var x = "|f|oo||"; 
x =  x.trimChars('|'); // f|oo

Since I use the trimChars function extensively in one of my scripts, I prefer this solution. But there are potential issues with modifying an object's prototype.

Of course you can.

Your HTML there is just fine. To style the elements with css you can use the following approaches:

#y {
    ...
}

.x {
    ...
}

#y.x {
    ...
}

Also you can add as many classes as you wish to your element

<div id="id" class="classA classB classC ...">
</div>

And you can style that element using a selector with any combination of the classes and id. For example:

#id.classA.classB.classC {
     ...
}

#id.classC {
}

You need to use latest/newest

GoogleApiClient Api

Basically what you need to do is:

private GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

Then

@Override
    public void onConnected(Bundle connectionHint) {
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
            mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
        }
    }

for the most accurate and reliable location. See my post here:

https://stackoverflow.com/a/33599228/2644905

Do not use LocationListener which is not accurate and has delayed response. To be honest this is easier to implement. Also read documentation: https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApiClient

var icon1 = "imageA.png";
var icon2 = "imageB.png";

var marker = new google.maps.Marker({
    position: myLatLng,
    map: map,
    icon: icon1,
    title: "some marker"
});

google.maps.event.addListener(marker, 'mouseover', function() {
    marker.setIcon(icon2);
});
google.maps.event.addListener(marker, 'mouseout', function() {
    marker.setIcon(icon1);
});

import os

def count_files(in_directory):
    joiner= (in_directory + os.path.sep).__add__
    return sum(

        for filename
        in map(joiner, os.listdir(in_directory))
    )

Just call plt.show() at the end:

import numpy as np
import matplotlib.pyplot as plt

plt.axis([0,50,60,80])
for i in np.arange(1,5):
    z = 68 + 4 * np.random.randn(50)
    zm = np.cumsum(z) / range(1,len(z)+1)
    plt.plot(zm)    

n = np.arange(1,51)
su = 68 + 4 / np.sqrt(n)
sl = 68 - 4 / np.sqrt(n)

plt.plot(n,su,n,sl)

plt.show()

all answers so far use some version of forEach, iterating over all collection elements client-side.

However, you could use MongoDB's server-side processing by using aggregate pipeline and $out stage as :

the $out stage atomically replaces the existing collection with the new results collection.

example:

db.documents.aggregate([
         {
            $project: {
               _id: 1,
               numberField: { $substr: ['$numberField', 0, -1] },
               otherField: 1,
               differentField: 1,
               anotherfield: 1,
               needolistAllFieldsHere: 1
            },
         },
         {
            $out: 'documents',
         },
      ]);

Array starts from index 0 and ends at n-1.

static void Main(string[] args)
{
    int[] arr = { 1, 2, 3, 4, 5 };
    int length = arr.Length - 1;   // starts from 0 to n-1

    Console.WriteLine(length);     // this will give the last index.
    Console.Read();
}

Realizing that this is a rather old post, I'll provide an answer anyway as I was struggling with the same problem.

You should use the "input" event instead, and register with the .on method. This is fast - without the lag of keyup and solves the missing latest keypress problem you describe.

$('#dSuggest').on("input", function() {
    var dInput = this.value;
    console.log(dInput);
    $(".dDimension:contains('" + dInput + "')").css("display","block");
});

import sys
sys.exit(1)

This works for me for the iphone 6

/*iPhone 6 Portrait*/
@media only screen and (min-device-width: 375px) and (max-device-width: 667px) and (orientation : portrait) { 

}

/*iPhone 6 landscape*/
@media only screen and (min-device-width: 375px) and (max-device-width: 667px) and (orientation : landscape) { 

}

/*iPhone 6+ Portrait*/
@media only screen and (min-device-width: 414px) and (max-device-width: 736px) and (orientation : portrait) { 

}

/*iPhone 6+ landscape*/
@media only screen and (min-device-width: 414px) and (max-device-width: 736px) and (orientation : landscape) { 

}

/*iPhone 6 and iPhone 6+ portrait and landscape*/
@media only screen and (max-device-width: 640px), only screen and (max-device-width: 667px), only screen and (max-width: 480px){ 
}

/*iPhone 6 and iPhone 6+ portrait*/
@media only screen and (max-device-width: 640px), only screen and (max-device-width: 667px), only screen and (max-width: 480px) and (orientation : portrait){ 

}

/*iPhone 6 and iPhone 6+ landscape*/
@media only screen and (max-device-width: 640px), only screen and (max-device-width: 667px), only screen and (max-width: 480px) and (orientation : landscape){ 

}

That works well.

If adding more than one option element, I'd recommend performing the append once as opposed to performing an append on each element.

Every time you call the jQuery() function, a new object is created and returned. So even equality checks on the same selectors will fail.

<div id="a">test</div>

$('#a') == $('#a') // false

The resulting jQuery object contains an array of matching elements, which are basically native DOM objects like HTMLDivElement that always refer to the same object, so you should check those for equality using the array index as Darin suggested.

$('#a')[0] == $('#a')[0] // true

Here is what I tried to fix the issue and it worked:

1. Manually deleted the existing plugin from the .m2 repo
2. Enabled "use plugin registry" in IntelliJ
3. Invalidated the cache and restarted IntelliJ
4. Reimported the maven project in IntelliJ

After following above steps, the issue was fixed. Hopefully this helps you as well.

• Starting with Java 8, there is no "medium" risk setting in the Security tab under Java

• You will keep getting this error till you revert to older Java (suggested Java 7, it has hit the end of life though).

• Install both 32-bit and 64-bit version because browsers are still 32-bit, even on a 64-bit machine, 64-bit OS

You can convert an int to an unsigned int. The conversion is valid and well-defined.

Since the value is negative, UINT_MAX + 1 is added to it so that the value is a valid unsigned quantity. (Technically, 2^N is added to it, where N is the number of bits used to represent the unsigned type.)

In this case, since int on your platform has a width of 32 bits, 62 is subtracted from 2³², yielding 4,294,967,234.

Here are some more exotic Python 3 ways to get "hello" TAB "alex" (tested with Python 3.6.10):

"hello\N{TAB}alex"

"hello\N{tab}alex"

"hello\N{TaB}alex"

"hello\N{HT}alex"

"hello\N{CHARACTER TABULATION}alex"

"hello\N{HORIZONTAL TABULATION}alex"

"hello\x09alex"

"hello\u0009alex"

"hello\U00000009alex"

Actually, instead of using an escape sequence, it is possible to insert tab symbol directly into the string literal. Here is the code with a tabulation character to copy and try:

"hello alex"

If the tab in the string above won't be lost anywhere during copying the string then "print(repr(< string from above >)" should print 'hello\talex'.

See respective Python documentation for reference.

Just add the column names, yes you can use Null instead but is is a very bad idea to not use column names in any insert, ever.

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

Your query has 8 or possibly even 9 variables, ie. Name, Description etc. But the values, these things ---> '', '%s', '%s', '%s', '%s', '%s', '%s', '%s')", only total 7, the number of variables have to be the same as the values.

I had the same problem but I figured it out. Hopefully it will also work for you.

Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;

Yes, it is possible to run PowerShell through the run window. However, it would be burdensome and you will need to enter in the password for computer. This is similar to how you will need to set up when you run cmd:

runas /user:(ComputerName)\(local admin) powershell.exe

So a basic example would be:

runas /user:MyLaptop\[email protected]  powershell.exe

You can find more information on this subject in Runas.

However, you could also do one more thing :

• 1: `Windows+R`
• 2: type: `powershell`
• 3: type: `Start-Process powershell -verb runAs`

then your system will execute the elevated powershell.

var size = 0;   
 var darray = new Array();
    function createTable(){
        darray[size] = new Array();
        darray[size][0] = $("#chqdate").val();
        darray[size][1]= $("#chqNo").val();
        darray[size][2] = $("#chqNarration").val() ;
        darray[size][3]= $("#chqAmount").val();
        darray[size][4]= $("#chqMode").val();
    }

increase size var after your function.

You can use this for the Width of your DataTemplate:

Width="{Binding ActualWidth,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ScrollContentPresenter}}}"

Make sure your DataTemplate root has Margin="0" (you can use some panel as the root and set the Margin to the children of that root)

sumall = summ + sumd + sumy

Your sumall is an integer. If you want the individual characters from it, convert it to a string first.

It seems that <TouchableHighlight> must have exactly one child. The docs say that it supports only one child and more than one must be wrapped in a <View>, but not that it must have at least (and most) one child. I just wanted to have a plain coloured button with no text/image, so I didn't deem it necessary to add a child.

I'll try to update the docs to indicate this.

i == 'InvKey' && i == 'PostDate' will never be true, since i can never equal two different things at once.

You're probably trying to write

if (i !== 'InvKey' && i !== 'PostDate')) 

I had the same issue. I found that ipython must be running for jupyter notebook to execute. Do the following:

• Go to the folder where you have your ipython notebook(.ipynb)
• Press shift and right click on the empty space then select "open command window here". This will open a command prompt window.
• Type ipython. This will start ipython.
• Open another command prompt window and open jupyter notebook.
• Open your file again and go to cell>>>run cell.

This should work. It worked for me. Cheers!

How about just mapping ....

Array(n).map((value, index) ....) is 80% of the way there. But for some odd reason it does not work. But there is a workaround.

Array(n).map((v,i) => i) // does not work
Array(n).fill().map((v,i) => i) // does dork

For a range

Array(end-start+1).fill().map((v,i) => i + start) // gives you a range

Odd, these two iterators return the same result: Array(end-start+1).entries() and Array(end-start+1).fill().entries()

<?php
//  Use this function and Pass Mixed string and what you want to search in mixed string.
//  For Example :
    $mixedStr = "hello world. This is john duvey";
    $searchStr= "john";

    if(strpos($mixedStr,$searchStr)) {
      echo "Your string here";
    }else {
      echo "String not here";
    }

As of python 2.7, optparse is deprecated, and will hopefully go away in the future.

argparse is better for all the reasons listed on its original page (https://code.google.com/archive/p/argparse/):

• handling positional arguments
• supporting sub-commands
• allowing alternative option prefixes like + and /
• handling zero-or-more and one-or-more style arguments
• producing more informative usage messages
• providing a much simpler interface for custom types and actions

More information is also in PEP 389, which is the vehicle by which argparse made it into the standard library.

running this command worked for me on my mac OS Catalina:

compaudit | xargs chmod g-w,o-w

Right click on the web page you want to use as the default page and choose "Set as Start Page" whenever you run the web application from Visual Studio, it will open the selected page.

That's something else then:

div.inline { float:left; }_x000D_
.clearBoth { clear:both; }

<div class="inline">1<br />2<br />3</div>_x000D_
<div class="inline">1<br />2<br />3</div>_x000D_
<div class="inline">1<br />2<br />3</div>_x000D_
<br class="clearBoth" /><!-- you may or may not need this -->

Using your radio button's ID, try rb.SelectedValue.

You can try _.isUndefined

<% if (!_.isUndefined(date)) { %><span class="date"><%= date %></span><% } %>

SET @customerID=0;
SELECT @customerID:=@customerID+1 AS customerID
FROM CUSTOMER ;

you can obtain the dataset from SQL like this and populate it into a java data structure (like a List) and then make the necessary sorting over there. (maybe with the help of a comparable interface)

If you need to match YYYY or YYYYMMDD you can use:

^((?:(?:(?:(?:(?:[1-9]\d)(?:0[48]|[2468][048]|[13579][26])|(?:(?:[2468][048]|[13579][26])00))(?:0?2(?:29)))|(?:(?:[1-9]\d{3})(?:(?:(?:0?[13578]|1[02])(?:31))|(?:(?:0?[13-9]|1[0-2])(?:29|30))|(?:(?:0?[1-9])|(?:1[0-2]))(?:0?[1-9]|1\d|2[0-8])))))|(?:19|20)\d{2})$

Create the macro as here:

On the Tools menu in Microsoft Excel, point to Macro, and then click Visual Basic Editor. On the Insert menu, click Module. Copy and paste this code into the code window of the module. It will automatically name itself HyperAdd.

Sub HyperAdd()

    'Converts each text hyperlink selected into a working hyperlink

    For Each xCell In Selection
        ActiveSheet.Hyperlinks.Add Anchor:=xCell, Address:=xCell.Formula
    Next xCell

End Sub

When you're finished pasting your macro, click Close and Return to Microsoft Excel on the File menu.

Then select the required cells and click macro and click run.

NOTE Do NOT select the whole column! Select ONLY the cells you wish to be changed to clickable links else you will end up in a neverending loop and have to restart Excel! Done!

getView() method in Adapter is for generating item's view of a ListView, Gallery,...

1. LayoutInflater is used to get the View object which you define in a layout xml (the root object, normally a LinearLayout, FrameLayout, or RelativeLayout)

2. convertView is for recycling. Let's say you have a listview which can only display 10 items at a time, and currently it is displaying item 1 -> item 10. When you scroll down one item, the item 1 will be out of screen, and item 11 will be displayed. To generate View for item 11, the getView() method will be called, and convertView here is the view of item 1 (which is not neccessary anymore). So instead create a new View object for item 11 (which is costly), why not re-use convertView? => we just check convertView is null or not, if null create new view, else re-use convertView.

3. parentView is the ListView or Gallery... which contains the item's view which getView() generates.

Note: you don't call this method directly, just need to implement it to tell the parent view how to generate the item's view.

• from a directory_of_modules, you can import a specific_module.py
• this specific_module.py, can contain a Class with some_methods() or just functions()
• from a specific_module.py, you can instantiate a Class or call functions()
• from this Class, you can execute some_method()

Example:

#!/usr/bin/python3
from directory_of_modules import specific_module
instance = specific_module.DbConnect("username","password")
instance.login()

Excerpts from PEP 8 - Style Guide for Python Code:

Modules should have short and all-lowercase names.

Notice: Underscores can be used in the module name if it improves readability.

A Python module is simply a source file(*.py), which can expose:

• Class: names using the "CapWords" convention.

• Function: names in lowercase, words separated by underscores.

• Global Variables: the conventions are about the same as those for Functions.

You can put enum values to list of strings and convert to array:

    List<String> stateList = new ArrayList<>();

            for (State state: State.values()) {
                stateList.add(state.toString());
            }

    String[] stateArray = new String[stateList.size()];
    stateArray = stateList.toArray(stateArray);

This works in python 2 and 3 and is a bit cleaner than before, but requires SA>=1.0.

from sqlalchemy.engine.default import DefaultDialect
from sqlalchemy.sql.sqltypes import String, DateTime, NullType

# python2/3 compatible.
PY3 = str is not bytes

class StringLiteral(String):
    """Teach SA how to literalize various things."""
    def literal_processor(self, dialect):
        super_processor = super(StringLiteral, self).literal_processor(dialect)

        def process(value):
            if isinstance(value, int_type):
                return text(value)
            if not isinstance(value, str_type):
                value = text(value)
            result = super_processor(value)
            if isinstance(result, bytes):
                result = result.decode(dialect.encoding)
            return result
        return process


class LiteralDialect(DefaultDialect):
    colspecs = {
        # prevent various encoding explosions
        String: StringLiteral,
        # teach SA about how to literalize a datetime
        DateTime: StringLiteral,
        # don't format py2 long integers to NULL
        NullType: StringLiteral,
    }


def literalquery(statement):
    """NOTE: This is entirely insecure. DO NOT execute the resulting strings."""
    import sqlalchemy.orm
    if isinstance(statement, sqlalchemy.orm.Query):
        statement = statement.statement
    return statement.compile(
        dialect=LiteralDialect(),
        compile_kwargs={'literal_binds': True},
    ).string

Demo:

# coding: UTF-8
from datetime import datetime
from decimal import Decimal

from literalquery import literalquery


def test():
    from sqlalchemy.sql import table, column, select

    mytable = table('mytable', column('mycol'))
    values = (
        5,
        u'snowman: ?',
        b'UTF-8 snowman: \xe2\x98\x83',
        datetime.now(),
        Decimal('3.14159'),
        10 ** 20,  # a long integer
    )

    statement = select([mytable]).where(mytable.c.mycol.in_(values)).limit(1)
    print(literalquery(statement))


if __name__ == '__main__':
    test()

Gives this output: (tested in python 2.7 and 3.4)

SELECT mytable.mycol
FROM mytable
WHERE mytable.mycol IN (5, 'snowman: ?', 'UTF-8 snowman: ?',
      '2015-06-24 18:09:29.042517', 3.14159, 100000000000000000000)
 LIMIT 1
