I forgot to select the column (or set/map the property to a column value):

IQueryable<SampleTable> queryable = from t in dbcontext.SampleTable
                                    where ...
                                    select new DataModel { Name = t.Name };

Calling queryable.OrderBy("Id") will throw exception, even though DataModel has property Id defined.

The correct query is:

IQueryable<SampleTable> queryable = from t in dbcontext.SampleTable
                                    where ...
                                    select new DataModel { Name = t.Name, Id = t.Id };

In pure SQL the main statement kools like:

INSERT INTO [simbs] ([En]) OUTPUT INSERTED.[ID] VALUES ('en')

Square brackets defines the table simbs and then the columns En and ID, round brackets defines the enumeration of columns to be initiated and then the values for the columns, in my case one column and one value. The apostrophes enclose a string

I will explain you my approach:

It might be not easy to understand but i hope useful to get the big picture around using the last inserted id. Of course there are alternative easier approaches. But I have reasons to keep mine. Associated functions are not included, just their names and parameter names.

I use this method for medical artificial intelligence The method check if the wanted string exist in the central table (1). If the wanted string is not in the central table "simbs", or if duplicates are allowed, the wanted string is added to the central table "simbs" (2). The last inseerted id is used to create associated table (3).

    public List<int[]> CreateSymbolByName(string SymbolName, bool AcceptDuplicates)
    {
        if (! AcceptDuplicates)  // check if "AcceptDuplicates" flag is set
        {
            List<int[]> ExistentSymbols = GetSymbolsByName(SymbolName, 0, 10); // create a list of int arrays with existent records
            if (ExistentSymbols.Count > 0) return ExistentSymbols; //(1) return existent records because creation of duplicates is not allowed
        }
        List<int[]> ResultedSymbols = new List<int[]>();  // prepare a empty list
        int[] symbolPosition = { 0, 0, 0, 0 }; // prepare a neutral position for the new symbol
        try // If SQL will fail, the code will continue with catch statement
        {
            //DEFAULT und NULL sind nicht als explizite Identitätswerte zulässig
            string commandString = "INSERT INTO [simbs] ([En]) OUTPUT INSERTED.ID VALUES ('" + SymbolName + "') "; // Insert in table "simbs" on column "En" the value stored by variable "SymbolName"
            SqlCommand mySqlCommand = new SqlCommand(commandString, SqlServerConnection); // initialize the query environment
                SqlDataReader myReader = mySqlCommand.ExecuteReader(); // last inserted ID is recieved as any resultset on the first column of the first row
                int LastInsertedId = 0; // this value will be changed if insertion suceede
                while (myReader.Read()) // read from resultset
                {
                    if (myReader.GetInt32(0) > -1) 
                    {
                        int[] symbolID = new int[] { 0, 0, 0, 0 };
                        LastInsertedId = myReader.GetInt32(0); // (2) GET LAST INSERTED ID
                        symbolID[0] = LastInsertedId ; // Use of last inserted id
                        if (symbolID[0] != 0 || symbolID[1] != 0) // if last inserted id succeded
                        {
                            ResultedSymbols.Add(symbolID);
                        }
                    }
                }
                myReader.Close();
            if (SqlTrace) SQLView.Log(mySqlCommand.CommandText); // Log the text of the command
            if (LastInsertedId > 0) // if insertion of the new row in the table was successful
            {
                string commandString2 = "UPDATE [simbs] SET [IR] = [ID] WHERE [ID] = " + LastInsertedId + " ;"; // update the table by giving to another row the value of the last inserted id
                SqlCommand mySqlCommand2 = new SqlCommand(commandString2, SqlServerConnection); 
                mySqlCommand2.ExecuteNonQuery();
                symbolPosition[0] = LastInsertedId; // mark the position of the new inserted symbol
                ResultedSymbols.Add(symbolPosition); // add the new record to the results collection
            }
        }
        catch (SqlException retrieveSymbolIndexException) // this is executed only if there were errors in the try block
        {
            Console.WriteLine("Error: {0}", retrieveSymbolIndexException.ToString()); // user is informed about the error
        }

        CreateSymbolTable(LastInsertedId); //(3) // Create new table based on the last inserted id
        if (MyResultsTrace) SQLView.LogResult(LastInsertedId); // log the action
        return ResultedSymbols; // return the list containing this new record
    }

What does the UDF EntityHasProfile() do?

Typically you could do something like this with a LEFT JOIN:

SELECT EntityId, EntityName, CASE WHEN EntityProfileIs IS NULL THEN 0 ELSE 1 END AS Has Profile
FROM Entities
LEFT JOIN EntityProfiles
    ON EntityProfiles.EntityId = Entities.EntityId

This should eliminate a need for a costly scalar UDF call - in my experience, scalar UDFs should be a last resort for most database design problems in SQL Server - they are simply not good performers.

I had a similar problem and what I did to overcome it was the following:

1. Stop the service: net stop "ServiceName"
2. Ensure: the "mmc.exe" process does not exist (The "Services" list window): taskkill /F /IM mmc.exe

3. Delete the service: sc delete "ServiceName"

   C:\server>sc delete "ServiceName"
   
   [SC] DeleteService SUCCESS
   

Now, if I execute another sc command, what I get is the following:

C:\server>sc delete "ServiceName"

[SC] OpenService FAILED 1060:

The specified service does not exist as an installed service.

But not the 1072 error message

There are all kinds of wonderful ways to specify commits - see the specifying revisions section of man git-rev-parse for more details. In this case, you probably want:

git diff HEAD@{1}

The @{1} means "the previous position of the ref I've specified", so that evaluates to what you had checked out previously - just before the pull. You can tack HEAD on the end there if you also have some changes in your work tree and you don't want to see the diffs for them.

I'm not sure what you're asking for with "the commit ID of my latest version of the file" - the commit "ID" (SHA1 hash) is that 40-character hex right at the top of every entry in the output of git log. It's the hash for the entire commit, not for a given file. You don't really ever need more - if you want to diff just one file across the pull, do

git diff HEAD@{1} filename

This is a general thing - if you want to know about the state of a file in a given commit, you specify the commit and the file, not an ID/hash specific to the file.

You missed the * in front of NgIf (like we all have, dozens of times):

<div *ngIf="answer.accepted">&#10004;</div>

Without the *, Angular sees that the ngIf directive is being applied to the div element, but since there is no * or <template> tag, it is unable to locate a template, hence the error.

If you get this error with Angular v5:

Error: StaticInjectorError[TemplateRef]:
  StaticInjectorError[TemplateRef]:
    NullInjectorError: No provider for TemplateRef!

You may have <template>...</template> in one or more of your component templates. Change/update the tag to <ng-template>...</ng-template>.

The use of http.createClient is now deprecated. You can pass Headers in options collection as below.

var options = { 
    hostname: 'example.com',
    path: '/somePath.php',
    method: 'GET',
    headers: {'Cookie': 'myCookie=myvalue'}
};
var results = ''; 
var req = http.request(options, function(res) {
    res.on('data', function (chunk) {
        results = results + chunk;
        //TODO
    }); 
    res.on('end', function () {
        //TODO
    }); 
});

req.on('error', function(e) {
        //TODO
});

req.end();

I think "works fine in Firefox" is in the Quirks mode rendering only. In the Standard mode rendering, that might not work fine in Firefox too.

percentage depends on "containing block", instead of viewport.

CSS Specification says

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

so

#container { height: auto; }
#container #mainContentsWrapper { height: n%; }
#container #sidebarWrapper { height: n%; }

means

#container { height: auto; }
#container #mainContentsWrapper { height: auto; }
#container #sidebarWrapper { height: auto; }

To stretch to 100% height of viewport, you need to specify the height of the containing block (in this case, it's #container). Moreover, you also need to specify the height to body and html, because initial Containing Block is "UA-dependent".

All you need is...

html, body { height:100%; }
#container { height:100%; }

You may like to first create a dialogue by right clicking the project in solution explorer and in the code file type

dialogue1.show()

that's all !!!

Either directly in form parameters or

string controlName = this.Request.Params.Get("__EVENTTARGET");

Edit: To check if a control caused a postback (manually):

// input Image with name="imageName"
if (this.Request["imageName"+".x"] != null) ...;//caused postBack

// Other input with name="name"
if (this.Request["name"] != null) ...;//caused postBack

You could also iterate through all the controls and check if one of them caused a postBack using the above code.

This exception means that there is no service listening on the IP/port you are trying to connect to:

• You are trying to connect to the wrong IP/Host or port.
• You have not started your server.
• Your server is not listening for connections.
• On Windows servers, the listen backlog queue is full.

As was indicated by others, you don't need to use malloc just to do:

const char *foo = "bar";

The reason for that is exactly that *foo is a pointer — when you initialize foo you're not creating a copy of the string, just a pointer to where "bar" lives in the data section of your executable. You can copy that pointer as often as you'd like, but remember, they're always pointing back to the same single instance of that string.

So when should you use malloc? Normally you use strdup() to copy a string, which handles the malloc in the background. e.g.

const char *foo = "bar";
char *bar = strdup(foo); /* now contains a new copy of "bar" */
printf("%s\n", bar);     /* prints "bar" */
free(bar);               /* frees memory created by strdup */

Now, we finally get around to a case where you may want to malloc if you're using sprintf() or, more safely snprintf() which creates / formats a new string.

char *foo = malloc(sizeof(char) * 1024);        /* buffer for 1024 chars */
snprintf(foo, 1024, "%s - %s\n", "foo", "bar"); /* puts "foo - bar\n" in foo */
printf(foo);                                    /* prints "foo - bar" */
free(foo);                                      /* frees mem from malloc */

Use MyISAM for very unimportant data or if you really need those minimal performance advantages. The read performance is not better in every case for MyISAM.

I would personally never use MyISAM at all anymore. Choose InnoDB and throw a bit more hardware if you need more performance. Another idea is to look at database systems with more features like PostgreSQL if applicable.

EDIT: For the read-performance, this link shows that innoDB often is actually not slower than MyISAM: https://www.percona.com/blog/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1/

If you want only spaces, then how about:

String spaces = (n==0)?"":String.format("%"+n+"s", "");

which will result in abs(n) spaces;

If you use GUID as primary key and create clustered index then I suggest use the default of NEWSEQUENTIALID() value for it.

If RAM is not an issue using insertMany is way faster than forEach loop.

var db1 = connect('<ip_1>:<port_1>/<db_name_1>')
var db2 = connect('<ip_2>:<port_2>/<db_name_2>')

var _list = db1.getCollection('collection_to_copy_from').find({})
db2.collection_to_copy_to.insertMany(_list.toArray())

we can use \b as a word boundary and then; \b\d+\b

Look if the package have an official fork that include the necessary binary wheels.

I needed the package python-Levenshtein, had this error, and find the package python-Levenshtein-wheels instead.

There is also a slight difference in the html output for a string data type.

Html.EditorFor:  
<input id="Contact_FirstName" class="text-box single-line" type="text" value="Greg" name="Contact.FirstName">

Html.TextBoxFor:
<input id="Contact_FirstName" type="text" value="Greg" name="Contact.FirstName">

There are two ways to solve the issue "cannot be resolved to a type ":

1. For non maven project, add jars manually in a folder and add it in java build path. This would solve the compilation errors.
2. For maven project, right click on the project and go to maven -> update project. Select all the projects where you are getting compilation errors and also check "Force update of snapshots/releases". This will update the project and fix the compilation errors.

As I just figured, in case you have a model fitted on multiple linear regression, the above mentioned solution won't work.

You have to create your line manually as a dataframe that contains predicted values for your original dataframe (in your case data).

It would look like this:

# read dataset
df = mtcars

# create multiple linear model
lm_fit <- lm(mpg ~ cyl + hp, data=df)
summary(lm_fit)

# save predictions of the model in the new data frame 
# together with variable you want to plot against
predicted_df <- data.frame(mpg_pred = predict(lm_fit, df), hp=df$hp)

# this is the predicted line of multiple linear regression
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = predicted_df, aes(x=mpg_pred, y=hp))

# this is predicted line comparing only chosen variables
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_smooth(method = "lm", se = FALSE)

In my case an additional file not belonging to the database was inside the database folder. Mysql found the folder not empty after dropping all tables which triggered the error. I remove the file and the drop database worked fine.

window.print();  

unless you mean a custom looking popup.

just came across while browsing, might help you javascript-getting-and-setting-caret-position-in-textarea. You can use it for textbox also.

You could use the Directory class

 Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories)

Here are all the possible problems/solutions I have come across:

1. Download the cookie plugin

$.cookie is not a standard jQuery function and the plugin needs to be downloaded here. Make sure to include the appropriate <script> tag where necessary (see next).

2. Include jQuery before the cookie plugin

When including the cookie script, make sure to include jQuery FIRST, then the cookie plugin.

<script src="~/Scripts/jquery-2.0.3.js" type="text/javascript"></script>
<script src="~/Scripts/jquery_cookie.js" type="text/javascript"></script>

3. Don't include jQuery more than once

This was my problem. Make sure you aren't including jQuery more than once. If you are, it is possible that:

1. jQuery loads correctly.
2. The cookie plugin loads correctly.
3. Your second inclusion of jQuery overwrites the first and destroys the cookie plugin.

For anyone using ASP.Net MVC projects, be careful with the default javascript bundle inclusions. My second inclusion of jQuery was within one of my global layout pages under the line @Scripts.Render("~/bundles/jquery").

4. Rename the plugin file to not include ".cookie"

In some rare cases, renaming the file to something that does NOT include ".cookie" has fixed this error, apparently due to web server issues. By default, the downloaded script is titled "jquery.cookie.js" but try renaming it to something like "jquery_cookie.js" as shown above. More details on this problem are here.

Here is how to modify cron a entry without directly editing the cron file (which is frowned upon).

crontab -l -u <user> | sed 's/find/replace/g' | crontab -u <user> -

If you want to remove a cron entry, use this:

crontab -l -u <user> | sed '/find/d' | crontab -u <user> -

I realize this is not what gaurav was asking for, but why not have all the solutions in one place?

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

To follow up on @MrSnowflake answer with a code example. This is the XABBER now open source Application class. The Application class is centralising and coordinating Listeners and ManagerInterfaces and more. Managers of all sorts are dynamically loaded. Activity´s started in the Xabber will report in what type of Listener they are. And when a Service start it report in to the Application class as started. Now to send a message to an Activity all you have to do is make your Activity become a listener of what type you need. In the OnStart() OnPause() register/unreg. The Service can ask the Application class for just that listener it need to speak to and if it's there then the Activity is ready to receive.

Going through the Application class you'll see there's a loot more going on then this.

If you need direct access:

WScript.Arguments.Item(0)
WScript.Arguments.Item(1)
...

You need to pass the labels to be dropped.

df.drop(df.index, inplace=True)

By default, it operates on axis=0.

You can achieve the same with

df.iloc[0:0]

which is much more efficient.

I find a case is if your url contains the key word banner, it will blocked too.

You are right. This has nothing to do with jQuery though.

var myArray = [];
myArray.push("foo");
// myArray now contains "foo" at index 0.

this solved it npm cache clean --force

The question is old but there is now this kind of desired function. I added a wrapper with not, left shift and dec.

You can use a wrapper function based on signbit from C99 in order to get the exact desired behavior (see code further below).

Returns whether the sign of x is negative.
This can be also applied to infinites, NaNs and zeroes (if zero is unsigned, it is considered positive

#include <math.h>

int signValue(float a) {
    return ((!signbit(a)) << 1) - 1;
}

NB: I use operand not ("!") because the return value of signbit is not specified to be 1 (even though the examples let us think it would always be this way) but true for a negative number:

Return value
A non-zero value (true) if the sign of x is negative; and zero (false) otherwise.

Then I multiply by two with left shift (" << 1") which will give us 2 for a positive number and 0 for a negative one and finally decrement by 1 to obtain 1 and -1 for respectively positive and negative numbers as requested by OP.

Late to the game, but you can also use a localisation file

DataTable provides a .json localized file, which contains the key sEmptyTable and the corresponding localized message.

For example, just download the localized json file on the above link, then initialize your Datatable like that :

$('#example').dataTable( {
    "language": {
        "url": "path/to/your/json/file.json"
    }
});

IMHO, that's a lot cleaner, because your localized content is located in an external file.

This syntax works for DataTables 1.10.16, I didn't test on previous versions.

SELECT * FROM Member WHERE month(date_created) = month(NOW() - INTERVAL 1 MONTH);

It may be too late now, I use index method to retrieve last index of a DataFrame, then use [-1] to get the last values:

For example,

df = pd.DataFrame(np.zeros((4, 1)), columns=['A'])
print(f'df:\n{df}\n')

print(f'Index = {df.index}\n')
print(f'Last index = {df.index[-1]}')

The output is

df:
     A
0  0.0
1  0.0
2  0.0
3  0.0

Index = RangeIndex(start=0, stop=4, step=1)

Last index = 3

I tried several of these techniques, and the following worked for me, so if all else here if all else fails then try this because it worked for me :).

<style>
  #footer {
    height:30px;
    margin: 0;
    clear: both;
    width:100%;
    position: relative;
    bottom:-10;
  }
</style>

<div id="footer" >Sportkin - the registry for sport</div>

Some people posted the link to this bootstrap-datepicker.js implementation. I used that one in the following way, it works with Bootstrap 3.

This is the markup I used:

<div class="input-group date col-md-3" data-date-format="dd-mm-yyyy" data-date="01-01-2014">                        
    <input id="txtHomeLoanStartDate" class="form-control" type="text" readonly="" value="01-01-2014" size="14" />
    <span class="input-group-addon add-on">
        <span class="glyphicon glyphicon-calendar"</span>
    </span>
</div>

This is the javascript:

$('.date').datepicker();

I also included the javascript file downloaded from the link above, along with it's css file, and of course, you should remove any bootstrap grid classes like the col-md-3 to suit your needs.

I believe you may simply do:

ImageConverter converter = new ImageConverter();
var bytes = (byte[])converter.ConvertTo(img, typeof(byte[]));

I know it's malapropos, but IMHO easy way is:

def insert (source_str, insert_str, pos):
    return source_str[:pos]+insert_str+source_str[pos:]

IBAction and IBOutlets are used to hook up your interface made in Interface Builder with your controller. If you wouldn't use Interface Builder and build your interface completely in code, you could make a program without using them. But in reality most of us use Interface Builder, once you want to get some interactivity going in your interface, you will have to use IBActions and IBoutlets.

The following function will delete the input character one by one till the input field is empty using PromiseWhile

driver.clearKeys = function(element, value){
  return element.getAttribute('value').then(function(val) {
    if (val.length > 0) {
      return new Promise(function(resolve, reject) {
        var len;
        len = val.length;
        return promiseWhile(function() { 
          return 0 < len;
        }, function() {
          return new Promise(function(resolve, reject) {
            len--;
            return element.sendKeys(webdriver.Key.BACK_SPACE).then(function()              {
              return resolve(true);
            });
          });
        }).then(function() {
          return resolve(true);
        });
      });
    }

If you need to echo a string that contains an ampersand, quotes won't help, because you would see them on the output as well. In such a case, use for:

for %a in ("First & Last") do echo %~a

...in a batch script:

for %%a in ("First & Last") do echo %%~a

or

for %%a in ("%~1") do echo %%~a

For shared libraries libNAME.so the -D switch was necessary to see symbols in my Linux

nm -D libNAME.so

and for static library as reported by others

nm -g libNAME.a

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

m = [[1, 1, 1, 0],[0, 5, 0, 1],[2, 1, 3, 10]]

print(len(m),len(m[0]))

Output

(3 4)

The magic you have been looking for has been added in Rails 6 Now you can upsert (update or insert). For single record use:

Model.upsert(column_name: value)

For multiple records use upsert_all :

Model.upsert_all(column_name: value, unique_by: :column_name)

Note:

• Both methods do not trigger Active Record callbacks or validations
• unique_by => PostgreSQL and SQLite only

Almost all the other answers are replacing the string being split which wastes CPU cycles and performs unnecessary memory allocations.

I cover a much better way to do a string split here: http://www.digitalruby.com/split-string-sql-server/

Here is the code:

SET NOCOUNT ON

-- You will want to change nvarchar(MAX) to nvarchar(50), varchar(50) or whatever matches exactly with the string column you will be searching against
DECLARE @SplitStringTable TABLE (Value nvarchar(MAX) NOT NULL)
DECLARE @StringToSplit nvarchar(MAX) = 'your|string|to|split|here'
DECLARE @SplitEndPos int
DECLARE @SplitValue nvarchar(MAX)
DECLARE @SplitDelim nvarchar(1) = '|'
DECLARE @SplitStartPos int = 1

SET @SplitEndPos = CHARINDEX(@SplitDelim, @StringToSplit, @SplitStartPos)

WHILE @SplitEndPos > 0
BEGIN
    SET @SplitValue = SUBSTRING(@StringToSplit, @SplitStartPos, (@SplitEndPos - @SplitStartPos))
    INSERT @SplitStringTable (Value) VALUES (@SplitValue)
    SET @SplitStartPos = @SplitEndPos + 1
    SET @SplitEndPos = CHARINDEX(@SplitDelim, @StringToSplit, @SplitStartPos)
END

SET @SplitValue = SUBSTRING(@StringToSplit, @SplitStartPos, 2147483647)
INSERT @SplitStringTable (Value) VALUES(@SplitValue)

SET NOCOUNT OFF

-- You can select or join with the values in @SplitStringTable at this point.

Here is a version that works well in September 2020 using fetch and https://worldtimeapi.org/api

fetch("https://worldtimeapi.org/api/ip")
  .then(response => response.json())
  .then(data => console.log(data.timezone,data.datetime,data.dst));

SELECT *
FROM A.tableA JOIN B.tableB 

or

SELECT *
  FROM A.tableA JOIN B.tableB
  ON A.tableA.id = B.tableB.a_id;

Android N (Api level 24) update (no warnings):

   Locale getCurrentLocale(Context context){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
            return context.getResources().getConfiguration().getLocales().get(0);
        } else{
            //noinspection deprecation
            return context.getResources().getConfiguration().locale;
        }
    }

If you're just doing some quick and dirty temporary work, you can also skip typing out an explicit CREATE TABLE statement and just make the temp table with a SELECT...INTO and include an Identity field in the select list.

select IDENTITY(int, 1, 1) as ROW_ID,
       Name
into #tmp
from (select 'Bob' as Name union all
      select 'Susan' as Name union all
      select 'Alice' as Name) some_data

select *
from #tmp

For those that just used a standard form submit (non-AJAX), there's another way to fire some Javascript/JQuery code upon completion of your action.

First, create a string property on your Model.

public class MyModel 
{
    public string JavascriptToRun { get; set;}
}

Now, bind to your new model property in the Javascript of your view:

<script type="text/javascript">
     @Model.JavascriptToRun
</script>

Now, also in your view, create a Javascript function that does whatever you need to do:

<script type="text/javascript">
     @Model.JavascriptToRun

     function ShowErrorPopup() {
          alert('Sorry, we could not process your order.');
     }

</script>

Finally, in your controller action, you need to call this new Javascript function:

[HttpPost]
public ActionResult PurchaseCart(MyModel model)
{
    // Do something useful
    ...

    if (success == false)
    {
        model.JavascriptToRun= "ShowErrorPopup()";
        return View(model);
    }
    else
        return RedirectToAction("Success");
}

Ctrl + F12 also works well on linux(ubuntu).

You can access columns by index, by name and some other ways:

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

You should probably make sure your DataTable has some columns first...

you'd better off modifying server roles, which was designed for security privileges. add sysadmin server role to your user. for better security you may have your custom server roles. but this approach will give you what you want for now.

1. Object Explorer -> Server -> Security -> Logins
2. Right click on your desired user
3. Go to Server Roles on left hand side
4. Make sure sysadmin is checked
5. Hit OK and restart your SQL server

Good luck

add "MainContent_" to ID value!

Example: (Error)

document.getElementById("Password").value = text;

(ok!)

document.getElementById("**MainContent_**Password").value = text;

I had same problem with UnicodeDecodeError and i solved it with this line. Don't know if is the best way but it worked for me.

str = str.decode('unicode_escape').encode('utf-8')

You need to reference the cout's namespace std somehow. For instance, insert

using std::cout;
using std::endl;

on top of your function definition, or the file.

Just check this:

$(document).ready(function() {
    $(".scroll").click(function(event){
        $('html, body').animate({scrollTop: '+=150px'}, 800);
    });
});

It will make scroller scroll from current position when your element is clicked

And 150px is used to scroll for 150px downwards

You can't. The -c switch tells you when the permissions were last changed, -a tests the most recent access time, and -m tests the modification time. The filesystem used by most flavors of Linux (ext3) doesn't support a "creation time" record. Sorry!

There is still no solution that preserves newlines.

This is not true - you're probably just being misled by the behaviour of echo:

echo $VAR # strips newlines

echo "$VAR" # preserves newlines

I know the topic is old, but I just fell on it after a google search so... here is another solution:

$array_merged = array_merge($array_going_first, $array_going_second);

This one seems pretty clean to me, it works just fine!

I know this is a little late but better late than never! Here's a really simple way to achieve this. Simply have a show and hide function. The hide function will just append every option element to a predetermined (hidden) span tag (which should work for all browsers) and then the show function will just move that option element back into your select tag. ;)

function showOption(value){
    $('#optionHolder option[value="'+value+'"]').appendTo('#selectID');             
}

function hideOption(value){
    $('select option[value="'+value+'"]').appendTo('#optionHolder');
}

To be simple,

Mono is third party implementation of .Net framework for Linux/Android/iOs

.Net Core is microsoft's own implementation for same.

.Net Core is future. and Mono will be dead eventually. Having said that .Net Core is not matured enough. I was struggling to implement it with IBM Bluemix and later dropped the idea. Down the time (may be 1-2 years), it should be better.

I was in need of copying the data from one workbook to another using VBA. The requirement was as mentioned below 1. On pressing an Active X button open the dialogue to select the file from which the data needs to be copied. 2. On clicking OK the value should get copied from a cell / range to currently working workbook.

I did not want to use the open function because it opens the workbook which will be annoying

Below is the code that I wrote in the VBA. Any improvement or new alternative is welcome.

Code: Here I am copying the A1:C4 content from a workbook to the A1:C4 of current workbook

Enqueue means to add an element, dequeue to remove an element.

var stackInput= []; // First stack
var stackOutput= []; // Second stack

// For enqueue, just push the item into the first stack
function enqueue(stackInput, item) {
  return stackInput.push(item);
}

function dequeue(stackInput, stackOutput) {
  // Reverse the stack such that the first element of the output stack is the
  // last element of the input stack. After that, pop the top of the output to
  // get the first element that was ever pushed into the input stack
  if (stackOutput.length <= 0) {
    while(stackInput.length > 0) {
      var elementToOutput = stackInput.pop();
      stackOutput.push(elementToOutput);
    }
  }

  return stackOutput.pop();

$results = DB::table('rooms')
                     ->distinct()
                     ->leftJoin('bookings', function($join)
                         {
                             $join->on('rooms.id', '=', 'bookings.room_type_id');
                             $join->on('arrival','>=',DB::raw("'2012-05-01'"));
                             $join->on('arrival','<=',DB::raw("'2012-05-10'"));
                             $join->on('departure','>=',DB::raw("'2012-05-01'"));
                             $join->on('departure','<=',DB::raw("'2012-05-10'"));
                         })
                     ->where('bookings.room_type_id', '=', NULL)
                     ->get();

Not quite sure if the between clause can be added to the join in laravel.

Notes:

• DB::raw() instructs Laravel not to put back quotes.
• By passing a closure to join methods you can add more join conditions to it, on() will add AND condition and orOn() will add OR condition.

The basic distinction, though, is that functional tests test the application from the outside, from the point of view of the user. Unit tests test the application from the inside, from the point of view of the programmer. Functional tests should help you build an application with the right functionality, and guarantee you never accidentally break it. Unit tests should help you to write code that’s clean and bug free.

For Windows 7 (Professional, 64-bit - can't speak for the others) I see that REG no longer spits out

! REG.EXE VERSION 3.0

as it does in XP. So the above needs to be modified to use

skip=2

instead of 4 - which makes things messy if you want your script to be portable. Although it's much more heavyweight and complex, a WMIC based solution may be better.

...additionally make sure to use:

mongoose.Promise = Promise;

This sets the mongoose promise to the native ES6 promise. Without this addition I got:

DeprecationWarning: Mongoose: mpromise (mongoose's default promise library) is deprecated, plug in your own promise library instead: http://mongoosejs.com/docs/promises.html

Try the following:

PreparedStatementCreator creator = new PreparedStatementCreator() {
    @Override
    public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
        PreparedStatement updateSales = con.prepareStatement(
        "UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ? ");
        updateSales.setInt(1, 75); 
        updateSales.setString(2, "Colombian"); 
        return updateSales;
    }
};

Typescript is (a superset of) javascript, so you just use JSON.parse as you would in javascript:

let obj = JSON.parse(jsonString);

Only that in typescript you can have a type to the resulting object:

interface MyObj {
    myString: string;
    myNumber: number;
}

let obj: MyObj = JSON.parse('{ "myString": "string", "myNumber": 4 }');
console.log(obj.myString);
console.log(obj.myNumber);

I had a similar problem which I could solve by granting execute-privilege for all parent folders in which the jar-file is located (on a linux system).

Example:

/folder1/folder2/folder3/executable.jar

all 3 folders (folder1, folder2 and folder3) as well as the executable.jar need execute-privilege for the current user, otherwise the error "Could not find or load main class ..." is returned.

best way copy the ? symbol and paste it.

Here is a refactored and simplified version of the @sasha_gud answer:

    [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
    [return: MarshalAs(UnmanagedType.Bool)]
    public static extern bool GetDiskFreeSpaceEx(string lpDirectoryName,
        out ulong lpFreeBytesAvailable,
        out ulong lpTotalNumberOfBytes,
        out ulong lpTotalNumberOfFreeBytes);

    public static ulong GetDiskFreeSpace(string path)
    {
        if (string.IsNullOrEmpty(path))
        {
            throw new ArgumentNullException("path");
        }

        ulong dummy = 0;

        if (!GetDiskFreeSpaceEx(path, out ulong freeSpace, out dummy, out dummy))
        {
            throw new Win32Exception(Marshal.GetLastWin32Error());
        }

        return freeSpace;
    }

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

Create a UIImageView and add UIImage to it:

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image Name"]] ;

Then add it to your view:

[self.view addSubView: imageView];

<a href="javascript:;" onclick="window.location = 'http://example.com/submit.php?url=' + escape(document.location.href);'">Go</a>;

Add the following lines to the [alias] section of your .gitconfig file

ignore = update-index --assume-unchanged
unignore = update-index --no-assume-unchanged
ignored = !git ls-files -v | grep "^[[:lower:]]"

Now you can use git ignore my_file to ignore changes to the local file, and git unignore my_file to stop ignoring the changes. git ignored lists the ignored files.

This answer was gleaned from http://gitready.com/intermediate/2009/02/18/temporarily-ignoring-files.html.

What do you mean by "version number"? It is quite common to tag a commit with a version number and then use

$ git describe --tags

to identify the current HEAD w.r.t. any tags. If you mean you want to know the hash of the current HEAD, you probably want:

$ git rev-parse HEAD

or for the short revision hash:

$ git rev-parse --short HEAD

It is often sufficient to do:

$ cat .git/refs/heads/${branch-master}

but this is not reliable as the ref may be packed.

DELIMITER ;;
CREATE TRIGGER `my_table_bi` BEFORE INSERT ON `my_table` FOR EACH ROW
BEGIN
    SET NEW.created_date = NOW();
END;;
DELIMITER ;

If I get 'someObject', say via

someObject <- myMagicFunction(...)

then I usually proceed by

class(someObject)
str(someObject)

which can be followed by head(), summary(), print(), ... depending on the class you have.

swift enforces you to initialise every member var before it is ever/might ever be used. Since it can't be sure what happens when it is supers turn, it errors out: better safe than sorry

You have to put the event handler in the $(document).ready() event:

$(document).ready(function() {
    $("#btnSubmit").click(function(){
        alert("button");
    }); 
});

SELECT * FROM products WHERE catid IN ('1', '2', '3', '4')

Set the height of the parent element, and give that the width. Then use a background image with the rule "background-size: cover"

    .parent {
       background-image: url(../img/team/bgteam.jpg);
       background-repeat: no-repeat;
       background-position: center center;
       -webkit-background-size: cover;
       background-size: cover;
    }

How about:

00 00  *  *   * every 3 days && echo test

Where every is a script:

#!/bin/sh

case $2 in
    days)
        expr `date +%j` % $1 = 0 > /dev/null
        ;;

    weeks)
        expr `date +%V` % $1 = 0 > /dev/null
        ;;

    months)
        expr `date +%m` % $1 = 0 > /dev/null
        ;;
esac

So it runs every day.

Using */3 runs on the 3rd, 6th, ... 27th, 30th of the month, but is then wrong after a month has a 31st day. The every script is only wrong after the end of the year.

This can be done using REGEXP_SUBSTR easily.

Please use

REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 

where STRING_EXAMPLE is your string.

Try:

SELECT 
REGEXP_SUBSTR('STRING_EXAMPLE','[^_]+',1,1) 
from dual

It will solve your problem.

The best way to do this is by running the command:

git diff --name-only --cached

When you check the manual you will likely find the following:

--name-only
    Show only names of changed files.

And on the example part of the manual:

git diff --cached
    Changes between the index and your current HEAD.

Combined together you get the changes between the index and your current HEAD and Show only names of changed files.

Update: --staged is also available as an alias for --cached above in more recent git versions.

1. First go through this tutorial for getting familiar with Android Google Maps and this for API 2.

2. To retrive the current location of device see this answer or this another answer and for API 2

3. Then you can get places near by your location using Google Place API and for use of Place Api see this blog.

4. After getting Placemarks of near by location use this blog with source code to show markers on map with balloon overlay with API 2.

5. You also have great sample to draw route between two points on map look here in these links Link1 and Link2 and this Great Answer.

After following these steps you will be easily able to do your application. The only condition is, you will have to read it and understand it, because like magic its not going to be complete in a click.

Using Apache Commons Lang:

!StringUtils.isAlphanumeric(String)

Alternativly iterate over String's characters and check with:

!Character.isLetterOrDigit(char)

You've still one problem left: Your example string "abcdefà" is alphanumeric, since à is a letter. But I think you want it to be considered non-alphanumeric, right?!

So you may want to use regular expression instead:

String s = "abcdefà";
Pattern p = Pattern.compile("[^a-zA-Z0-9]");
boolean hasSpecialChar = p.matcher(s).find();

The difference between compile time and run time is an example of what pointy-headed theorists call the phase distinction. It is one of the hardest concepts to learn, especially for people without much background in programming languages. To approach this problem, I find it helpful to ask

1. What invariants does the program satisfy?
2. What can go wrong in this phase?
3. If the phase succeeds, what are the postconditions (what do we know)?
4. What are the inputs and outputs, if any?

Compile time

1. The program need not satisfy any invariants. In fact, it needn't be a well-formed program at all. You could feed this HTML to the compiler and watch it barf...
2. What can go wrong at compile time:
   • Syntax errors
   • Typechecking errors
   • (Rarely) compiler crashes
3. If the compiler succeeds, what do we know?
   • The program was well formed---a meaningful program in whatever language.
   • It's possible to start running the program. (The program might fail immediately, but at least we can try.)
4. What are the inputs and outputs?
   • Input was the program being compiled, plus any header files, interfaces, libraries, or other voodoo that it needed to import in order to get compiled.
   • Output is hopefully assembly code or relocatable object code or even an executable program. Or if something goes wrong, output is a bunch of error messages.

Run time

1. We know nothing about the program's invariants---they are whatever the programmer put in. Run-time invariants are rarely enforced by the compiler alone; it needs help from the programmer.

2. What can go wrong are run-time errors:

   • Division by zero
   • Dereferencing a null pointer
   • Running out of memory

   Also there can be errors that are detected by the program itself:

   • Trying to open a file that isn't there
   • Trying find a web page and discovering that an alleged URL is not well formed
3. If run-time succeeds, the program finishes (or keeps going) without crashing.
4. Inputs and outputs are entirely up to the programmer. Files, windows on the screen, network packets, jobs sent to the printer, you name it. If the program launches missiles, that's an output, and it happens only at run time :-)

A minor addition to the answers already posted: object files not compiled to be position independent are relocatable; they contain relocation table entries.

These entries allow the loader (that bit of code that loads a program into memory) to rewrite the absolute addresses to adjust for the actual load address in the virtual address space.

An operating system will try to share a single copy of a "shared object library" loaded into memory with all the programs that are linked to that same shared object library.

Since the code address space (unlike sections of the data space) need not be contiguous, and because most programs that link to a specific library have a fairly fixed library dependency tree, this succeeds most of the time. In those rare cases where there is a discrepancy, yes, it may be necessary to have two or more copies of a shared object library in memory.

Obviously, any attempt to randomize the load address of a library between programs and/or program instances (so as to reduce the possibility of creating an exploitable pattern) will make such cases common, not rare, so where a system has enabled this capability, one should make every attempt to compile all shared object libraries to be position independent.

Since calls into these libraries from the body of the main program will also be made relocatable, this makes it much less likely that a shared library will have to be copied.

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

In order to make it work, you have to set property GroupName of both radio buttons to the same value:

<asp:RadioButton id="rbMetric" runat="server" GroupName="measurementSystem"></asp:RadioButton>
<asp:RadioButton id="rbUS" runat="server" GroupName="measurementSystem"></asp:RadioButton>

Personally, I prefer to use a RadioButtonList:

<asp:RadioButtonList ID="rblMeasurementSystem" runat="server">
    <asp:ListItem Text="Metric" Value="metric" />
    <asp:ListItem Text="US" Value="us" />
</asp:RadioButtonList>

I know it's late, but I take the original code and change some stuff to control easily the css. So I made a code with the addClass() and the removeClass()

Here the full code : http://jsfiddle.net/e5qaD/4837/

        if( bottom_of_window > bottom_of_object ){
            $(this).addClass('showme');
       }
        if( bottom_of_window < bottom_of_object ){
            $(this).removeClass('showme');

As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)

Duration column = End - Start

1. Once done, plot your stacked bar chart using the entire data.
2. Mark start and end range to no fill.
3. Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))

Good article here: Cross-domain communication with iframes

Also you can directly set document.domain the same in both frames (even

document.domain = document.domain;

code has sense because resets port to null), but this trick is not general-purpose.

I used GENEGC's script, but I found it quite slow.

It is slow because it scans whole sheet on every edit.

So I wrote way faster and cleaner method for myself and I wanted to share it.

function onEdit(e) {
    if (e) { 
        var ss = e.source.getActiveSheet();
        var r = e.source.getActiveRange(); 

        // If you want to be specific
        // do not work in first row
        // do not work in other sheets except "MySheet"
        if (r.getRow() != 1 && ss.getName() == "MySheet") {

            // E.g. status column is 2nd (B)
            status = ss.getRange(r.getRow(), 2).getValue();

            // Specify the range with which You want to highlight
            // with some reading of API you can easily modify the range selection properties
            // (e.g. to automatically select all columns)
            rowRange = ss.getRange(r.getRow(),1,1,19);

            // This changes font color
            if (status == 'YES') {
                rowRange.setFontColor("#999999");
            } else if (status == 'N/A') {
                rowRange.setFontColor("#999999");
            // DEFAULT
            } else if (status == '') { 
                rowRange.setFontColor("#000000");
            }   
        }
    }
}

Using the same center in the view and subview is the simplest way of doing it. You can do something like this,

UIView *innerView = ....;
innerView.view.center = self.view.center;
[self.view addSubView:innerView];

Since I prefer to list required arguments before optional, I hack around it via:

    parser = argparse.ArgumentParser()
    parser._action_groups.pop()
    required = parser.add_argument_group('required arguments')
    optional = parser.add_argument_group('optional arguments')
    required.add_argument('--required_arg', required=True)
    optional.add_argument('--optional_arg')
    return parser.parse_args()

and this outputs:

usage: main.py [-h] [--required_arg REQUIRED_ARG]
               [--optional_arg OPTIONAL_ARG]

required arguments:
  --required_arg REQUIRED_ARG

optional arguments:
  --optional_arg OPTIONAL_ARG

I can live without 'help' showing up in the optional arguments group.

I don't think you want the data from your Request, I think you want the data from your Response. The two are different. Also you should build your response correctly in your controller.

Looking at the class in edit #2, I would make it look like this:

class XmlController extends Controller
{
    public function index()
    {
        $content = Request::all();
        return Response::json($content);
    }
}

Once you've gotten that far you should check the content of your response in your test case (use print_r if necessary), you should see the data inside.

More information on Laravel responses here:

http://laravel.com/docs/5.0/responses

Using the native SQL Server Management Studio technique to export to CSV (as @8kb suggested) doesn't work if your values contain commas, because SSMS doesn't wrap values in double quotes. A more robust way that worked for me is to simply copy the results (click inside the grid and then CTRL-A, CTRL-C) and paste it into Excel. Then save as CSV file from Excel.

getopt Use command in your scripts to format any command line options or parameters.

#!/bin/bash
# Extract command line options & values with getopt
#
set -- $(getopt -q ab:cd "$@")
#
echo
while [ -n "$1" ]
do
case "$1" in
-a) echo "Found the -a option" ;;
-b) param="$2"
echo "Found the -b option, with parameter value $param"
shift ;;
-c) echo "Found the -c option" ;;
--) shift
break ;;
*) echo "$1 is not an option";;
esac
shift

I'm not sure if this is frowned upon or not, but this is how I do it...

Step 1 - I usually have a class that contains methods and variables that I want to access globally. In this example I'll call it the "App" class. Create a static Activity variable inside the class for each activity that your app has. Then create a static method called "close" that will run the finish() method on each of those Activity variables if they are NOT null. If you have a main/parent activity, close it last:

public class App
{
    ////////////////////////////////////////////////////////////////
    // INSTANTIATED ACTIVITY VARIABLES
    ////////////////////////////////////////////////////////////////

        public static Activity activity1;
        public static Activity activity2;
        public static Activity activity3;

    ////////////////////////////////////////////////////////////////
    // CLOSE APP METHOD
    ////////////////////////////////////////////////////////////////

        public static void close()
        {
            if (App.activity3 != null) {App.activity3.finish();}
            if (App.activity2 != null) {App.activity2.finish();}
            if (App.activity1 != null) {App.activity1.finish();}
        }
}

Step 2 - in each of your activities, override the onStart() and onDestroy() methods. In onStart(), set the static variable in your App class equal to "this". In onDestroy(), set it equal to null. For example, in the "Activity1" class:

@Override
public void onStart()
{
    // RUN SUPER | REGISTER ACTIVITY AS INSTANTIATED IN APP CLASS

        super.onStart();
        App.activity1 = this;
}

@Override
public void onDestroy()
{
    // RUN SUPER | REGISTER ACTIVITY AS NULL IN APP CLASS

        super.onDestroy();
        App.activity1 = null;
}

Step 3 - When you want to close your app, simply call App.close() from anywhere. All instantiated activities will close! Since you are only closing activities and not killing the app itself (as in your examples), Android is free to take over from there and do any necessary cleanup.

Again, I don't know if this would be frowned upon for any reason. If so, I'd love to read comments on why it is and how it can be improved!

I don't know about best book, but the purists might say Design Patterns: Elements of Reusable Object-Oriented Software

As far as my personal favorite, I like Head First Design Patterns published by O'Reilly. It's written in a conversational voice that appeals to me. When I read it, I reviewed my source code at the same time to see if it applied to what I was reading. If it did, I refactored. This is how I learned Chain of Responsibility.

Practice - Practice - Practice.

if you compile in C change

for (int i=0;i<10;i++) { ..

to

int i;
for (i=0;i<10;i++) { ..

You can also compile with the C99 switch set. Put -std=c99 in the compilation line:

gcc -std=c99 foo.c -o foo

I got the same error. I solved it moving the file applicationContext.xmlin a

sub-folder of the srcfolder. e.g:

context = new ClassPathXmlApplicationContext("/com/ejemplo/dao/applicationContext.xml");

The easiest way is to turn the int into a string and take each character of the string as an element of your list:

>>> n = 43365644 
>>> digits = [int(x) for x in str(n)]
>>> digits
[4, 3, 3, 6, 5, 6, 4, 4]
>>> lst.extend(digits)  # use the extends method if you want to add the list to another

It involves a casting operation, but it's readable and acceptable if you don't need extreme performance.

I've coded this for methods which expect to accept or return Iterable<?...>. Here is the code:

/**
 * Assuming the given method returns or takes an Iterable<T>, this determines the type T.
 * T may or may not extend WindupVertexFrame.
 */
private static Class typeOfIterable(Method method, boolean setter)
{
    Type type;
    if (setter) {
        Type[] types = method.getGenericParameterTypes();
        // The first parameter to the method expected to be Iterable<...> .
        if (types.length == 0)
            throw new IllegalArgumentException("Given method has 0 params: " + method);
        type = types[0];
    }
    else {
        type = method.getGenericReturnType();
    }

    // Now get the parametrized type of the generic.
    if (!(type instanceof ParameterizedType))
        throw new IllegalArgumentException("Given method's 1st param type is not parametrized generic: " + method);
    ParameterizedType pType = (ParameterizedType) type;
    final Type[] actualArgs = pType.getActualTypeArguments();
    if (actualArgs.length == 0)
        throw new IllegalArgumentException("Given method's 1st param type is not parametrized generic: " + method);

    Type t = actualArgs[0];
    if (t instanceof Class)
        return (Class<?>) t;

    if (t instanceof TypeVariable){
        TypeVariable tv =  (TypeVariable) actualArgs[0];
        AnnotatedType[] annotatedBounds = tv.getAnnotatedBounds();///
        GenericDeclaration genericDeclaration = tv.getGenericDeclaration();///
        return (Class) tv.getAnnotatedBounds()[0].getType();
    }

    throw new IllegalArgumentException("Unknown kind of type: " + t.getTypeName());
}

You can use Arrays.fill(array, -1).

You can do

document.getElementById(id) or 
$(id).length > 0

If you want to change background color, try this:

plt.rcParams['figure.facecolor'] = 'white'

As shown in the latest edit, the password is valid until 1970, which means it's currently invalid. This explains the error message which is the same as if the password was incorrect.

Reset the validity with:

ALTER USER postgres VALID UNTIL 'infinity';

In a recent question, another user had the same problem with user accounts and PG-9.2:

PostgreSQL - Password authentication fail after adding group roles

So apparently there is a way to unintentionally set a bogus password validity to the Unix epoch (1st Jan, 1970, the minimum possible value for the abstime type). Possibly, there's a bug in PG itself or in some client tool that would create this situation.

EDIT: it turns out to be a pgadmin bug. See https://dba.stackexchange.com/questions/36137/

Just to add an additional function should you need it. You can include a variable in the named location, for example a date identifier

date <- yyyymmdd
save(city, file=paste0("c:\\myuser\\somelocation\\",date,"_RData.Data")

This was you can always keep a check of when it was run

If your package name is more than two dot separated, say com.hello.world and moreover, you did not put anything in com/ and com/hello/. All of your classes are putting into com/hello/world/, you might DO the following steps to refactoring your package name(s) in Android Studio or IntelliJ:

• [FIRST] Add something under your directories(com/, com/hello/). You can achieve this by first add two files to package com.hello.world, say

   com.hello.world.PackageInfo1.java
   com.hello.world.PackageInfo2.java

then refactor them by moving them to com and com.hello respectively. You will see com and com.hello sitting there at the Project(Alt+1 or Command+1 for shortcut) and rename directories refactoring is waiting there as you expected.

• Refactor to rename one or more of these directories to reach your aim. The only thing you should notice here is you must choose the directories rather than Packages when a dialog ask you.

• If you've got lots of classes in your project, it will take you a while to wait for its auto-scan-and-rename.

• Besides, you need to rename the package name inside the AndroidManifest.xml manually, I guess, such that other names in this file can benefit the prefix.

• [ALSO], it might need you to replace all com.hello.world.R to the new XXX.XXX.XXX.R(Command+Shift+R for short)

• Rebuild and run your project to see whether it work. And use "Find in Path" to find other non-touch names you'd like to rename.

• Enjoy it.

Keep in mind, in the general case you could have multiple NAT translations going on, and multiple dns servers, each operating on different NAT translation levels.

What if you have carrier grade NAT, and want to communicate with other customers of the same carrier? In the general case you never know for sure because you might appear with different host names at every NAT translation.

I had same issue. I used PIL Image to load the images and converted to a numpy array then patched a rectangle using matplotlib. It was a jpg image, so there was no way for me to get the dpi from PIL img.info['dpi'], so the accepted solution did not work for me. But after some tinkering I figured out way to save the figure with the same size as the original.

I am adding the following solution here thinking that it will help somebody who had the same issue as mine.

import matplotlib.pyplot as plt
from PIL import Image
import numpy as np

img = Image.open('my_image.jpg') #loading the image
image = np.array(img) #converting it to ndarray
dpi = plt.rcParams['figure.dpi'] #get the default dpi value
fig_size = (img.size[0]/dpi, img.size[1]/dpi) #saving the figure size
fig, ax = plt.subplots(1, figsize=fig_size) #applying figure size
#do whatver you want to do with the figure
fig.tight_layout() #just to be sure
fig.savefig('my_updated_image.jpg') #saving the image

This saved the image with the same resolution as the original image.

In case you are not working with a jupyter notebook. you can get the dpi in the following manner.

figure = plt.figure()
dpi = figure.dpi

Super late to the party but I solved a similar problem with the approach of using .join("") to convert the array to one giant string, then using regex to .match(/.{1,7}/) it into arrays of substrings of max length 7.

const arr = ['abc', 'def', 'gh', 'ijkl', 'm', 'nopq', 'rs', 'tuvwx', 'yz'];
const arrayOfSevens = arr.join("").match(/.{1,7}/g);
// ["abcdefg", "hijklmn", "opqrstu", "vwxyz"]

Would be interesting to see how this performs in a speed test against other methods

How about generate based on time stamp rounded to the nearest millisecond, or whatever accuracy you need... then use a lock to synchronize access to the function.

If you store the last generated file name, you can append sequential letters or further digits to it as needed to make it unique.

Or if you'd rather do it without locks, use a time step plus a thread ID, and make sure that the function takes longer than a millisecond, or waits so that it does.

You can install other builds but not Appstore build.

From Xcode 8.2,drag and drop the build to simulator for the installation.

Some code examples for simple GET request. Maybe this helps understanding the difference. Using then:

$http.get('/someURL').then(function(response) {
    var data = response.data,
        status = response.status,
        header = response.header,
        config = response.config;
    // success handler
}, function(response) {
    var data = response.data,
        status = response.status,
        header = response.header,
        config = response.config;
    // error handler
});

Using success/error:

$http.get('/someURL').success(function(data, status, header, config) {
    // success handler
}).error(function(data, status, header, config) {
    // error handler
});

Please find the simple solution to convete Date & Time Format in Go Lang. Please find the example below.

Package Link: https://github.com/vigneshuvi/GoDateFormat.

Please find the plackholders:https://medium.com/@Martynas/formatting-date-and-time-in-golang-5816112bf098

package main


// Import Package
import (
    "fmt"
    "time"
    "github.com/vigneshuvi/GoDateFormat"
)

func main() {
    fmt.Println("Go Date Format(Today - 'yyyy-MM-dd HH:mm:ss Z'): ", GetToday(GoDateFormat.ConvertFormat("yyyy-MM-dd HH:mm:ss Z")))
    fmt.Println("Go Date Format(Today - 'yyyy-MMM-dd'): ", GetToday(GoDateFormat.ConvertFormat("yyyy-MMM-dd")))
    fmt.Println("Go Time Format(NOW - 'HH:MM:SS'): ", GetToday(GoDateFormat.ConvertFormat("HH:MM:SS")))
    fmt.Println("Go Time Format(NOW - 'HH:MM:SS tt'): ", GetToday(GoDateFormat.ConvertFormat("HH:MM:SS tt")))
}

func GetToday(format string) (todayString string){
    today := time.Now()
    todayString = today.Format(format);
    return
}

When the DLL was created an import lib is usually automatically created and you should use that linked in to your program along with header files to call it but if not then you can manually call windows functions like LoadLibrary and GetProcAddress to get it working.

Create a class that inherits from IActionFilter.

public class NoCacheAttribute : ActionFilterAttribute
{  
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}

Then put attributes where needed...

[NoCache]
[HandleError]
public class AccountController : Controller
{
    [NoCache]
    [Authorize]
    public ActionResult ChangePassword()
    {
        return View();
    }
}

SELECT * FROM table WHERE col >= '2010-10-01' AND col <= '2010-10-31'

var methods = [];
for (var key in foo.prototype) {
    if (typeof foo.prototype[key] === "function") {
         methods.push(key);
    }
}

You can simply loop over the prototype of a constructor and extract all methods.

The issue appears with parsing the JSON from request body, tipical for an invalid JSON. If you're using curl on windows, try escaping the json like -d "{"name":"value"}" or even -d "{"""name""":"value"""}"

On the other hand you can ommit the content-type header in which case whetewer is sent will be converted to your String argument

git branch --set-upstream <remote-branch>

sets the default remote branch for the current local branch.

Any future git pull command (with the current local branch checked-out),
will attempt to bring in commits from the <remote-branch> into the current local branch.

One way to avoid having to explicitly type --set-upstream is to use its shorthand flag -u as follows:

git push -u origin local-branch

This sets the upstream association for any future push/pull attempts automatically.
For more details, checkout this detailed explanation about upstream branches and tracking.

To avoid confusion, recent versions of git deprecate this somewhat ambiguous --set-upstream option in favour of a more verbose --set-upstream-to option with identical syntax and behaviour

git branch --set-upstream-to <origin/remote-branch>

I once tried to do those round corners and drop shadows with css3. Later on, I found it is still poorly supported (Internet Explorer(s), of course!)

I ended up trying to do that in JS (HTML canvas with IE Canvas), but it impacts the performance a lot (even on my C2D machine). In short, if you really need the effect, consider JS libraries (most of them should be able to run on IE6) but don't over do it due to performance issues; if you still need an alternative... you could use SFiR, then PS it and SFiR it. CSS3 isn't ready today.

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

If no access specifier is given, it's package-level access (there is no explicit specifier for this) for classes and class members. Interface methods are implicitly public.

The <Leader> key is mapped to \ by default. So if you have a map of <Leader>t, you can execute it by default with \+t. For more detail or re-assigning it using the mapleader variable, see

:help leader

To define a mapping which uses the "mapleader" variable, the special string
"<Leader>" can be used.  It is replaced with the string value of "mapleader".
If "mapleader" is not set or empty, a backslash is used instead.  
Example:
    :map <Leader>A  oanother line <Esc>
Works like:
    :map \A  oanother line <Esc>
But after:
    :let mapleader = ","
It works like:
    :map ,A  oanother line <Esc>

Note that the value of "mapleader" is used at the moment the mapping is
defined.  Changing "mapleader" after that has no effect for already defined
mappings.

If you want to be correct, use INFORMATION_SCHEMA.

SELECT * 
FROM information_schema.tables
WHERE table_schema = 'yourdb' 
    AND table_name = 'testtable'
LIMIT 1;

Alternatively, you can use SHOW TABLES

SHOW TABLES LIKE 'yourtable';

If there is a row in the resultset, table exists.

Another solution not mentioned yet is to use: rewind(stdin);

Number.prototype.toFixed is a function designed to format a number before printing it out. It's from the family of toString, toExponential and toPrecision.

To round a number, you would do this:

someNumber = 42.008;
someNumber = Math.round( someNumber * 1e2 ) / 1e2;
someNumber === 42.01;

// if you need 3 digits, replace 1e2 with 1e3 etc.
// or just copypaste this function to your code:

function toFixedNumber(num, digits, base){
  var pow = Math.pow(base||10, digits);
  return Math.round(num*pow) / pow;
}

.

Or if you want a “native-like” function, you can extend the prototype:

Number.prototype.toFixedNumber = function(digits, base){
  var pow = Math.pow(base||10, digits);
  return Math.round(this*pow) / pow;
}

someNumber = 42.008;
someNumber = someNumber.toFixedNumber(2);
someNumber === 42.01;


//or even hexadecimal

someNumber = 0xAF309/256  //which is af3.09
someNumber = someNumber.toFixedNumber(1, 16);
someNumber.toString(16) === "af3.1";

However, bear in mind that polluting the prototype is considered bad when you're writing a module, as modules shouldn't have any side effects. So, for a module, use the first function.

1. override hashCode() and equals(..) using those 4 fields
2. use new HashSet<Blog>(blogList) - this will give you a Set which has no duplicates by definition

Update: Since you can't change the class, here's an O(n^2) solution:

• create a new list
• iterate the first list
• in an inner loop iterate the second list and verify if it has an element with the same fields

You can make this more efficient if you provide a HashSet data structure with externalized hashCode() and equals(..) methods.

                alert($event);
          }
        });

1. Jar mismatch comes when you use library projects in your application and both projects are using same jar with different version so just check all library projects attached in your application. if some mismatch exist then remove it.

2. if above process is not working then just do remove project dependency from build path and again add library projects and build the application.

Intents are a way of telling Android what you want to do. In other words, you describe your intention. Intents can be used to signal to the Android system that a certain event has occurred. Other components in Android can register to this event via an intent filter.

Following are 2 types of intents

1.Explicit Intents

used to call a specific component. When you know which component you want to launch and you do not want to give the user free control over which component to use. For example, you have an application that has 2 activities. Activity A and activity B. You want to launch activity B from activity A. In this case you define an explicit intent targeting activityB and then use it to directly call it.

2.Implicit Intents

used when you have an idea of what you want to do, but you do not know which component should be launched. Or if you want to give the user an option to choose between a list of components to use. If these Intents are send to the Android system it searches for all components which are registered for the specific action and the data type. If only one component is found, Android starts the component directly. For example, you have an application that uses the camera to take photos. One of the features of your application is that you give the user the possibility to send the photos he has taken. You do not know what kind of application the user has that can send photos, and you also want to give the user an option to choose which external application to use if he has more than one. In this case you would not use an explicit intent. Instead you should use an implicit intent that has its action set to ACTION_SEND and its data extra set to the URI of the photo.

An explicit intent is always delivered to its target, no matter what it contains; the filter is not consulted. But an implicit intent is delivered to a component only if it can pass through one of the component's filters

Intent Filters

If an Intents is send to the Android system, it will determine suitable applications for this Intents. If several components have been registered for this type of Intents, Android offers the user the choice to open one of them.

This determination is based on IntentFilters. An IntentFilters specifies the types of Intent that an activity, service, orBroadcast Receiver can respond to. An Intent Filter declares the capabilities of a component. It specifies what anactivity or service can do and what types of broadcasts a Receiver can handle. It allows the corresponding component to receive Intents of the declared type. IntentFilters are typically defined via the AndroidManifest.xml file. For BroadcastReceiver it is also possible to define them in coding. An IntentFilters is defined by its category, action and data filters. It can also contain additional metadata.

If a component does not define an Intent filter, it can only be called by explicit Intents.

Following are 2 ways to define a filter

1.Manifest file

If you define the intent filter in the manifest, your application does not have to be running to react to the intents defined in it’s filter. Android registers the filter when your application gets installed.

2.BroadCast Receiver

If you want your broadcast receiver to receive the intent only when your application is running. Then you should define your intent filter during run time (programatically). Keep in mind that this works for broadcast receivers only.

you can set the PictureBox BackColor proprty to Transparent

As stated in the relevant RxJS documentation, the .subscribe() method can take a third argument that is called on completion if there are no errors.

For reference:

1. [onNext] (Function): Function to invoke for each element in the observable sequence.
2. [onError] (Function): Function to invoke upon exceptional termination of the observable sequence.
3. [onCompleted] (Function): Function to invoke upon graceful termination of the observable sequence.

Therefore you can handle your routing logic in the onCompleted callback since it will be called upon graceful termination (which implies that there won't be any errors when it is called).

this.httpService.makeRequest()
    .subscribe(
      result => {
        // Handle result
        console.log(result)
      },
      error => {
        this.errors = error;
      },
      () => {
        // 'onCompleted' callback.
        // No errors, route to new page here
      }
    );

As a side note, there is also a .finally() method which is called on completion regardless of the success/failure of the call. This may be helpful in scenarios where you always want to execute certain logic after an HTTP request regardless of the result (i.e., for logging purposes or for some UI interaction such as showing a modal).

Rx.Observable.prototype.finally(action)

Invokes a specified action after the source observable sequence terminates gracefully or exceptionally.

For instance, here is a basic example:

import { Observable } from 'rxjs/Rx';
import 'rxjs/add/operator/finally';

// ...

this.httpService.getRequest()
    .finally(() => {
      // Execute after graceful or exceptionally termination
      console.log('Handle logging logic...');
    })
    .subscribe (
      result => {
        // Handle result
        console.log(result)
      },
      error => {
        this.errors = error;
      },
      () => {
        // No errors, route to new page
      }
    );

for i in range(100):
try:
  #Your code here
  break
except:
  continue

This one worked for me.

Mostly we write below statement select * from table where length(ltrim(rtrim(field)))=10;

Use JMockit framework. It worked for me. You don't have to write statements for mocking DBConenction.getConnection() method. Just the below code is enough.

@Mock below is mockit.Mock package

Connection jdbcConnection = Mockito.mock(Connection.class);

MockUp<DBConnection> mockUp = new MockUp<DBConnection>() {

            DBConnection singleton = new DBConnection();

            @Mock
            public DBConnection getInstance() { 
                return singleton;
            }

            @Mock
            public Connection getConnection() {
                return jdbcConnection;
            }
         };

Why not set sample.png as background image of text or h2 css class? This will give effect as you have written over an image.

An iframe is used to embed another document inside a html page.

If the form is to be submitted to an iframe within the form page, then it can be easily acheived using the target attribute of the tag.

Set the target attribute of the form to the name of the iframe tag.

<form action="action" method="post" target="output_frame">
    <!-- input elements here --> 
</form>
<iframe name="output_frame" src="" id="output_frame" width="XX" height="YY">
</iframe>           

Advanced iframe target use
This property can also be used to produce an ajax like experience, especially in cases like file upload, in which case where it becomes mandatory to submit the form, in order to upload the files

The iframe can be set to a width and height of 0, and the form can be submitted with the target set to the iframe, and a loading dialog opened before submitting the form. So, it mocks a ajax control as the control still remains on the input form jsp, with the loading dialog open.

Exmaple

<script>
$( "#uploadDialog" ).dialog({ autoOpen: false, modal: true, closeOnEscape: false,                 
            open: function(event, ui) { jQuery('.ui-dialog-titlebar-close').hide(); } });

function startUpload()
{            
    $("#uploadDialog").dialog("open");
}

function stopUpload()
{            
    $("#uploadDialog").dialog("close");
}
</script>

<div id="uploadDialog" title="Please Wait!!!">
            <center>
            <img src="/imagePath/loading.gif" width="100" height="100"/>
            <br/>
            Loading Details...
            </center>
 </div>

<FORM  ENCTYPE="multipart/form-data" ACTION="Action" METHOD="POST" target="upload_target" onsubmit="startUpload()"> 
<!-- input file elements here--> 
</FORM>

<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;" onload="stopUpload()">   
        </iframe>

The easiest way I have tested just add a <br> as in the following:

<div class="col-sm-6">
    <br><h3><p class="text-center">Some Text</p></h3>
</div>

The only problem is that a extra line break (generated by that <br>) is generated when the screen gets smaller and it stacks. But it is quick and simple.

this work for me

    ncharacters.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent openncharacter = new Intent(getApplicationContext(),ncharacters.class);
            startActivity(openncharacter);
        }
    });

With the help of user=User.query.filter_by(username=form.username.data).first() statement you will get the specified user in user variable.

Now you can change the value of the new object variable like user.no_of_logins += 1 and save the changes with the session's commit method.

If you are using maven just do:

mvn eclipse:eclipse -DdownloadSources=true  -DdownloadJavadocs=true

I like the last two answers, but I experienced an issue if the the subclass referenced "this" in ngOnDestroy.

I modified it to be this, and it looks like it resolved that issue.

export abstract class BaseComponent implements OnDestroy {
    protected componentDestroyed$: Subject<boolean>;
    constructor() {
        this.componentDestroyed$ = new Subject<boolean>();
        let f = this.ngOnDestroy;
        this.ngOnDestroy = function()  {
            // without this I was getting an error if the subclass had
            // this.blah() in ngOnDestroy
            f.bind(this)();
            this.componentDestroyed$.next(true);
            this.componentDestroyed$.complete();
        };
    }
    /// placeholder of ngOnDestroy. no need to do super() call of extended class.
    ngOnDestroy() {}
}

I found this solution via PowerShell :

dir | rename-item -NewName {$_.name -replace "replaceME","MyNewTxt"}

This will rename parts of all the files in the current folder.

If you want to use $.getJSON() you can add the following before the call :

$.ajaxSetup({
    scriptCharset: "utf-8",
    contentType: "application/json; charset=utf-8"
});

You can use the charset you want instead of utf-8.

The options are explained here.

contentType : When sending data to the server, use this content-type. Default is application/x-www-form-urlencoded, which is fine for most cases.

scriptCharset : Only for requests with jsonp or script dataType and GET type. Forces the request to be interpreted as a certain charset. Only needed for charset differences between the remote and local content.

You may need one or both ...

I had a similar experience with Chai-Webdriver for Selenium. I added await to the assertion and it fixed the issue:

Example using Cucumberjs:

Then(/I see heading with the text of Tasks/, async function() {
    await chai.expect('h1').dom.to.contain.text('Tasks');
});

What I have found best is a CSRF token and save it in the session for links where you need to verify the referrer.

So if you are generating a FB callback then it would look something like this:

$token = uniqid(mt_rand(), TRUE);
$_SESSION['token'] = $token;
$url = "http://example.com/index.php?token={$token}";

Then the index.php will look like this:

if(empty($_GET['token']) || $_GET['token'] !== $_SESSION['token'])
{
    show_404();
} 

//Continue with the rest of code

I do know of secure sites that do the equivalent of this for all their secure pages.

This is probably due to your target server not having a valid SSL certificate.

If you are using Bootstrap date picker, then you can just add data_date_format attribute as below.

      @Html.TextBoxFor(m => m.StartDate, new { 
@id = "your-id", @class = "datepicker form-control input-datepicker", placeholder = "dd/mm/yyyy", data_date_format = "dd/mm/yyyy" 
})

If you are able to use a NSString only.

It's pretty similar to objective-c. All the data type are there but require the as NSString addition

    var x = "400.0" as NSString 

    x.floatValue //string to float
    x.doubleValue // to double
    x.boolValue // to bool
    x.integerValue // to integer
    x.intValue // to int

Also we have an toInt() function added See Apple Inc. “The Swift Programming Language.” iBooks. https://itun.es/us/jEUH0.l page 49

x.toInt()

Thanks to all, for me this solution worked: Magento 404 page in backoffice after login

PHP - shortest but precise

Here I rewrite my JS answer (math details are there) to PHP - you can run it here

function hsl2rgb($h,$s,$l) 
{
  $a = $s * min($l, 1-$l);
  $k = function($n,$h) { return ($n+$h/30)%12;};
  $f = function($n) use ($h,$s,$l,$a,$k) { 
      return $l - $a * max( min($k($n,$h)-3, 9-$k($n,$h), 1),-1);
  };
  return [ $f(0), $f(8), $f(4) ];
}   

*args just means that the function takes a number of arguments, generally of the same type.

Check out this section in the Python tutorial for more info.

In Swift 3:

label = UIFont.systemFont(ofSize: 20)

and to use system preset sizes, for example:

label = UIFont.systemFont(ofSize: UIFont.smallSystemFontSize)

I had the same issue. Turned out I used some external jars (apache poi 4.1.2) which were compiled with 1.8. Solved it by changing Java Build Path JRE to 1.8.

Many tricks work, but the Ajax request split the file name at 19 characters? Look at the output of the ajax request to see that:

The file name is okay to go into the href attribute, but the $(this).attr("href") use the text of the <a href='full/file/name' > Split file name </a>

So the $(data).find("a:contains(.jpg)") is not able to detect the extension.

I hope this is useful

var values = {};
$('td input').each(function(){
  values[$(this).attr('name')] = $(this).val();
}

Haven't tested, but that should do it...

^\+201[0|1|2|5][0-9]{8}

this regex matches Egyptian mobile numbers

JavaScript uses the \ (backslash) as an escape characters for:

• \' single quote
• \" double quote
• \ backslash
• \n new line
• \r carriage return
• \t tab
• \b backspace
• \f form feed
• \v vertical tab (IE < 9 treats '\v' as 'v' instead of a vertical tab ('\x0B'). If cross-browser compatibility is a concern, use \x0B instead of \v.)
• \0 null character (U+0000 NULL) (only if the next character is not a decimal digit; else it’s an octal escape sequence)

Note that the \v and \0 escapes are not allowed in JSON strings.

The cleanest approach is to use the Array#concat method; it will not create a new array (unlike Array#+ which will do the same thing but create a new array).

Straight from the docs (http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-concat):

concat(other_ary)

Appends the elements of other_ary to self.

So

[1,2].concat([3,4])  #=> [1,2,3,4]  

Array#concat will not flatten a multidimensional array if it is passed in as an argument. You'll need to handle that separately:

arr= [3,[4,5]]
arr= arr.flatten   #=> [3,4,5]
[1,2].concat(arr)  #=> [1,2,3,4,5]

Lastly, you can use our corelib gem (https://github.com/corlewsolutions/corelib) which adds useful helpers to the Ruby core classes. In particular we have an Array#add_all method which will automatically flatten multidimensional arrays before executing the concat.

Tail the log as a background job (&) and it will interleave with rspec output.

tail -f log/test.log &

Docker images are stored as filesystem layers. Every command in the Dockerfile creates a layer. You can also create layers by using docker commit from the command line after making some changes (via docker run probably).

These layers are stored by default under /var/lib/docker. While you could (theoretically) cherry pick files from there and install it in a different docker server, is probably a bad idea to play with the internal representation used by Docker.

When you push your image, these layers are sent to the registry (the docker hub registry, by default… unless you tag your image with another registry prefix) and stored there. When pushing, the layer id is used to check if you already have the layer locally or it needs to be downloaded. You can use docker history to peek at which layers (other images) are used (and, to some extent, which command created the layer).

As for options to share an image without pushing to the docker hub registry, your best options are:

• docker save an image or docker export a container. This will output a tar file to standard output, so you will like to do something like docker save 'dockerizeit/agent' > dk.agent.latest.tar. Then you can use docker load or docker import in a different host.

• Host your own private registry. - Outdated, see comments See the docker registry image. We have built an s3 backed registry which you can start and stop as needed (all state is kept on the s3 bucket of your choice) which is trivial to setup. This is also an interesting way of watching what happens when pushing to a registry

• Use another registry like quay.io (I haven't personally tried it), although whatever concerns you have with the docker hub will probably apply here too.

Try this using list comprehension:

import pandas as pd

df = pd.DataFrame(
    [p, p.team, p.passing_att, p.passer_rating()] for p in game.players.passing()
)

One already exists. If you cannot get over the "Move" syntax of the System.IO namespace. There is a static class FileSystem within the Microsoft.VisualBasic.FileIO namespace that has both a RenameDirectory and RenameFile already within it.

As mentioned by SLaks, this is just a wrapper for Directory.Move and File.Move.

In the package explorer, right-click on the package and select New -> File, then enter the filename including the ".properties" suffix.

Onchange is only fired when user enters something by keyboard. A possible workarround could be to first focus the textfield and then change it.

But why not fetch the event when the user clicks on a date? There already must be some javascript.

Try something like this (should work for Apache and IIS):

if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === "off") {
    $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $location);
    exit;
}

just wanted to leave my .scss example here, I think its kinda best practice, especially I think if you do customization its nice to set the width only once! It is not clever to apply it everywhere, you will increase the human factor exponentially.

Im looking forward for your feedback!

// Set your parameters
$widthSmall: 768px;
$widthMedium: 992px;

// Prepare your "function"
@mixin in-between {
     @media (min-width:$widthSmall) and (max-width:$widthMedium) {
        @content;
     }
}


// Apply your "function"
main {
   @include in-between {
      //Do something between two media queries
      padding-bottom: 20px;
   }
}

I think that you can use

for j,k in my_list:
  [ ... stuff ... ]

You can use ServerXMLHTTP in a VBA project by adding a reference to MSXML.

1. Open the VBA Editor (usually by editing a Macro)
2. Go to the list of Available References
3. Check Microsoft XML
4. Click OK.

(from Referencing MSXML within VBA Projects)

The ServerXMLHTTP MSDN documentation has full details about all the properties and methods of ServerXMLHTTP.

In short though, it works basically like this:

1. Call open method to connect to the remote server
2. Call send to send the request.
3. Read the response via responseXML, responseText, responseStream or responseBody

This is a basic move one repo to new location. I use this sequence all te time. With --bare no source files will be seen.

Open Git Bash.
Create a bare clone of the repository.

git clone --bare https://github.com/exampleuser/old-repository.git

Mirror-push to the new repository.

cd old-repository.git

git push --mirror https://github.com/exampleuser/new-repository.git

Remove the temporary local repository you created in step 1.

cd ../
rm -rf old-repository.git

Why mirror? See documentation of git: https://git-scm.com/docs/git-push

--all Push all branches (i.e. refs under refs/heads/); cannot be used with other .

--mirror Instead of naming each ref to push, specifies that all refs under refs/ (which includes but is not limited to refs/heads/, refs/remotes/, and refs/tags/) be mirrored to the remote repository. Newly created local refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end. This is the default if the configuration option remote..mirror is set.

JSON.stringify returns a String. So, for example:

var data = [
    { id: 1, name: "bob" },
    { id: 2, name: "john" },
    { id: 3, name: "jake" },
];

JSON.stringify(data)

will return the equivalent of:

"[{\"id\":1,\"name\":\"bob\"},{\"id\":2,\"name\":\"john\"},{\"id\":3,\"name\":\"jake\"}]"

as a String value.

So when you have

<% for(var i=0; i<JSON.stringify(data).length; i++) {%>

what that ends up looking like is:

<% for(var i=0; i<"[{\"id\":1,\"name\":\"bob\"},{\"id\":2,\"name\":\"john\"},{\"id\":3,\"name\":\"jake\"}]".length; i++) {%>

which is probably not what you want. What you probably do want is something like this:

<table>
<% for(var i=0; i < data.length; i++) { %>
   <tr>
     <td><%= data[i].id %></td>
     <td><%= data[i].name %></td>
   </tr>
<% } %>
</table>

This will output the following table (using the example data from above):

<table>
  <tr>
    <td>1</td>
    <td>bob</td>
  </tr>
  <tr>
    <td>2</td>
    <td>john</td>
  </tr>
  <tr>
    <td>3</td>
    <td>jake</td>
  </tr>
</table>

Initialize again select2 by new id or class like below

when the page load

$(".mynames").select2();

call again when came by ajax after success ajax function

$(".names").select2();

What is row?

Either of these could be correct.

1) I assume that you capture your ajax response in a javascript variable 'row'. If that is the case, this would hold true.

var result=row.split('|');
    alert(result[2]);

otherwise

2) Use this where $(row) is a jQuery object.

var result=$(row).val().split('|');
    alert(result[2]);

[As mentioned in the other answer, you may have to use $(row).val() or $(row).text() or $(row).html() etc. depending on what $(row) is.]

If you want an R solution, here's a small convenience function I sometimes use to find where the offending (multiByte) character is lurking. Note that it is the next character to what gets printed. This works because print will work fine, but substr throws an error when multibyte characters are present.

find_offending_character <- function(x, maxStringLength=256){  
  print(x)
  for (c in 1:maxStringLength){
    offendingChar <- substr(x,c,c)
    #print(offendingChar) #uncomment if you want the indiv characters printed
    #the next character is the offending multibyte Character
  }    
}

string_vector <- c("test", "Se\x96ora", "works fine")

lapply(string_vector, find_offending_character)

I fix that character and run this again. Hope that helps someone who encounters the invalid multibyte string error.

There is a danger with using the <input type="text" pattern="\d*"> to bring up the numeric keyboard. On firefox and chrome, the regular expression contained within the pattern causes the browser to validate the input to that expression. errors will occur if it doesn't match the pattern or is left blank. Be aware of unintended actions in other browsers.

Based on CQM's answer and on ovokerie-ogbeta's answer to another question I've come up with this solution:

if (colorAsString.length() == 4) { // #XXX
    colorAsString = colorAsString.replaceAll("#([0-9a-fA-F])([0-9a-fA-F])([0-9a-fA-F])", "#$1$1$2$2$3$3");
}

int color = Color.parseColor(colorAsString);

It seems that since XCode 7.x a lot of warnings are coming out when enabling clang module with CLANG_ENABLE_MODULES

Take a look at Lots of warnings when building with Xcode 7 with 3rd party libraries

You could use asprintf to concatenate both into a new string:

char *new_str;
asprintf(&new_str,"%s%s",str1,str2);

There is no such feature in PostgreSQL. You can do it only in pl/PgSQL (or other pl/*), but not in plain SQL.

An exception is WITH () query which can work as a variable, or even tuple of variables. It allows you to return a table of temporary values.

WITH master_user AS (
    SELECT
      login,
      registration_date
    FROM users
    WHERE ...
)

SELECT *
FROM users
WHERE master_login = (SELECT login
                      FROM master_user)
      AND (SELECT registration_date
           FROM master_user) > ...;
