Basically:

if (variable >= 5 && variable <= 100)
{
    doSomething();
}

If you really needed to use a switch, it would be because you need to do various things for certain ranges. In that case, yes, you're going to have messy code, because things are getting complex and only things which follow patterns are going to compress well.

The only reason for a switch is to save on typing the variable name if you're just testing for numeric switching values. You aren't going to switch on 100 things, and they aren't going to be all doing the same thing. That sounds more like an 'if' chunk.

Here dataTpe is "json" so, data/reqParam must be in the form of string while calling API, many as much as object as you want but at last inside $.ajax's data stringify the object.

             let person= {  name: 'john',
                age: 22
            };

           var personStr = JSON.stringify(person); 

            $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: JSON.stringify( { param1: personStr } ),
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

OR,

       $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: personStr,
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

Select the div which has role dialog then get the appropriate buttons in it and set the CSS.

$("div[role=dialog] button:contains('Save')").css("color", "green");
$("div[role=dialog] button:contains('Cancel')").css("color", "red"); 

The primary difference is that SELECT INTO MyTable will create a new table called MyTable with the results, while INSERT INTO requires that MyTable already exists.

You would use SELECT INTO only in the case where the table didn't exist and you wanted to create it based on the results of your query. As such, these two statements really are not comparable. They do very different things.

In general, SELECT INTO is used more often for one off tasks, while INSERT INTO is used regularly to add rows to tables.

EDIT:
While you can use CREATE TABLE and INSERT INTO to accomplish what SELECT INTO does, with SELECT INTO you do not have to know the table definition beforehand. SELECT INTO is probably included in SQL because it makes tasks like ad hoc reporting or copying tables much easier.

may need to change the SCHEMA not only table

ALTER SCHEMA `<database name>`  DEFAULT CHARACTER SET utf8mb4  DEFAULT COLLATE utf8mb4_unicode_ci (as Rich said - utf8mb4);

Just using the event object

function search(e) {
    e = e || window.event;
    if(e.keyCode == 13) {
        var elem = e.srcElement || e.target;
        alert(elem.value);
    }
}

I wrote how to write LaTeX in Jupyter Notebook in this article.

You need to enclose them in dollar($) signs.

• To align to the left use a single dollar($) sign.

$P(A)=\frac{n(A)}{n(U)}$

• To align to the center use double dollar($$) signs.

$$P(A)=\frac{n(A)}{n(U)}$$

• Use \limits for \lim, \sum and \int to add limits to the top and the bottom of each sign.

• Use a backslash to escape LaTeX special words such as Math symbols, Latin words, text, etc.

Try this one.

$$\overline{x}=\frac{\sum \limits _{i=1} ^k f_i x_i}{n} \text{, where } n=\sum \limits _{i=1} ^k f_i  $$

• Matrices

• Piecewise functions

$$
\begin{align}
\text{Probability density function:}\\
\begin{cases}
\frac{1}{b-a}&\text{for $x\in[a,b]$}\\
0&\text{otherwise}\\
\end{cases}
\\
\text{Cumulative distribution function:}\\
\begin{cases}
0&\text{for $x<a$}\\
\frac{x-a}{b-a}&\text{for $x\in[a,b)$}\\
1&\text{for $x\ge b$}\\
\end{cases}
\end{align}
$$

The above code will create this.

Say you have a big table called orders, and a small table called customers. There is a foreign key from an order to a customer. Now if you delete a customer, Sql Server must check that there are no orphan orders; if there are, it raises an error.

To check if there are any orders, Sql Server has to search the big orders table. Now if there is an index, the search will be fast; if there is not, the search will be slow.

So in this case, the slow delete could be explained by the absence of an index. Especially if Sql Server would have to search 15 big tables without an index.

P.S. If the foreign key has ON DELETE CASCADE, Sql Server still has to search the order table, but then to remove any orders that reference the deleted customer.

For me the solution is to kill zombie IIS express worker processes.

e.g. locate in Task Manager and end task.

I encountered the same error message.

I built the cmocka as a so and tried to link it to my executable. But ld always complains below:

/usr/bin/ld: cannot find -lcmocka

It turns out that there are 3 files generated after cmocka is built:

1. libcmocka.so
2. libcmocka.so.0
3. libcmocka.so.0.7.0

1 and 2 are symbol links and only 3 is the real file.

I only copied the 1 to my library folder, where ld failed to find the 3.

After I copied all 3, ld works.

If you're using the South package to handle database migrations (highly recommended), then you could just use the ./manage.py migrate appname zero command.

Otherwise, I'd recommend the ./manage.py dbshell command, piping in SQL commands on standard input.

just put

$a='Link1';
$b='Link2';

in your pass.php and you will get your answer and do a double quotation in your link.php:

echo '<a href="pass.php?link=' . $a . '">Link 1</a>';

try with either of the 2 below commands

/usr/local/mysql/bin/mysql -uroot
-- OR --
/usr/local/Cellar/mysql/<version>/bin/mysql -uroot

To avoid placing HTML tags in the title attribute, another solution is to use markdown. For instance, you could use [br] to represent a line break, then perform a simple replace in the content function.

In title attribute:

"Sample Line 1[br][br]Sample Line 2"

In your content function:

content: function () {
    return $(this).attr('title').replace(/\[br\]/g,"<br />");
}

You can achieve that using DATE_FORMAT() (click the link for more other formats)

SELECT DATE_FORMAT(colName, '%Y-%m-%d') DATEONLY, 
       DATE_FORMAT(colName,'%H:%i:%s') TIMEONLY

SQLFiddle Demo

this ended up working for me:

   gpg -a --export-secret-keys > exportedKeyFilename.asc 

you can name keyfilename.asc by any name as long as you keep on the .asc extension.
this command copies all secret-keys on a user's computer to keyfilename.asc in the working directory of where the command was called.

To Export just 1 specific secret key instead of all of them:

   gpg -a --export-secret-keys keyIDNumber > exportedKeyFilename.asc

keyIDNumber is the number of the key id for the desired key you are trying to export.

On Ubuntu, placed your id_rsa and id_rsa.pub files in /var/lib/jenkins/.ssh

Make Jenkins own them sudo chown -R jenkins /var/lib/jenkins/.ssh/

Make sure that Jenkins key is added as deploy key with RW access in GitHub (or similar) - use the id_rsa.pub key for this.

Now everything should jive with the SCM Sync Plugin.

The need for C++ delegate implementations are a long lasting embarassment to the C++ community. Every C++ programmer would love to have them, so they eventually use them despite the facts that:

1. std::function() uses heap operations (and is out of reach for serious embedded programming).

2. All other implementations make concessions towards either portability or standard conformity to larger or lesser degrees (please verify by inspecting the various delegate implementations here and on codeproject). I have yet to see an implementation which does not use wild reinterpret_casts, Nested class "prototypes" which hopefully produce function pointers of the same size as the one passed in by the user, compiler tricks like first forward declare, then typedef then declare again, this time inheriting from another class or similar shady techniques. While it is a great accomplishment for the implementers who built that, it is still a sad testimoney on how C++ evolves.

3. Only rarely is it pointed out, that now over 3 C++ standard revisions, delegates were not properly addressed. (Or the lack of language features which allow for straightforward delegate implementations.)

4. With the way C++11 lambda functions are defined by the standard (each lambda has anonymous, different type), the situation has only improved in some use cases. But for the use case of using delegates in (DLL) library APIs, lambdas alone are still not usable. The common technique here, is to first pack the lambda into a std::function and then pass it across the API.

It's only necessary to prepare the string variable first and then convert it to the RegEx.

for example:

You want to add minLength and MaxLength with the variable to RegEx:

function getRegEx() {
    const minLength = "5"; // for exapmle: min is 5
    const maxLength = "12"; // for exapmle: man is 12

    var regEx = "^.{" + minLength + ","+ maxLength +"}$"; // first we make a String variable of our RegEx
    regEx = new RegExp(regEx, "g"); // now we convert it to RegEx

    return regEx; // In the end, we return the RegEx
}

now if you change value of MaxLength or MinLength, It will change in all RegExs.

Hope to be useful. Also sorry about my English.

You need to add a Custom Action to the end of the 'ExecuteImmediate' sequence in the MSI, using the component name of the EXE or a batch (sc start) as the source. I don't think this can be done with Visual Studio, you may have to use a real MSI authoring tool for that.

It registers the driver; something of the form:

public class SomeDriver implements Driver {
  static {
    try {
      DriverManager.registerDriver(new SomeDriver());
    } catch (SQLException e) {
      // TODO Auto-generated catch block
    }
  }

  //etc: implemented methods
}

Try with this:

long abc=convertString2Hex("1A2A3B");

private  long  convertString2Hex(String numberHexString)
{
    char[] ChaArray = numberHexString.toCharArray();
    long HexSum=0;
    long cChar =0;

    for(int i=0;i<numberHexString.length();i++ )
    {
        if( (ChaArray[i]>='0') && (ChaArray[i]<='9') )
            cChar = ChaArray[i] - '0';
        else
            cChar = ChaArray[i]-'A'+10;
        HexSum = 16 * HexSum + cChar;
    }
    return  HexSum;
}

In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325

Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.

Make sure that you have checked it to work properly with the IE version you specify.

You need to convert the String object into an array of char using the toCharArray() method of the String class:

String str = "xyz";
char arr[] = str.toCharArray(); // convert the String object to array of char

// iterate over the array using the for-each loop.       
for(char c: arr){
    System.out.println(c);
}

You will also get this error message when you accidentally forget to define a setter for a property. For example:

public class Building
{
    public string Description { get; }
}

var query = 
    from building in context.Buildings
    select new
    {
        Desc = building.Description
    };
int count = query.ToList();

The call to ToList will give the same error message. This one is a very subtle error and very hard to detect.

While only a few lines are required to plot multiple/overlapping histograms in ggplot2, the results are't always satisfactory. There needs to be proper use of borders and coloring to ensure the eye can differentiate between histograms.

The following functions balance border colors, opacities, and superimposed density plots to enable the viewer to differentiate among distributions.

Single histogram:

plot_histogram <- function(df, feature) {
    plt <- ggplot(df, aes(x=eval(parse(text=feature)))) +
    geom_histogram(aes(y = ..density..), alpha=0.7, fill="#33AADE", color="black") +
    geom_density(alpha=0.3, fill="red") +
    geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
    labs(x=feature, y = "Density")
    print(plt)
}

Multiple histogram:

plot_multi_histogram <- function(df, feature, label_column) {
    plt <- ggplot(df, aes(x=eval(parse(text=feature)), fill=eval(parse(text=label_column)))) +
    geom_histogram(alpha=0.7, position="identity", aes(y = ..density..), color="black") +
    geom_density(alpha=0.7) +
    geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
    labs(x=feature, y = "Density")
    plt + guides(fill=guide_legend(title=label_column))
}

Usage:

Simply pass your data frame into the above functions along with desired arguments:

plot_histogram(iris, 'Sepal.Width')

plot_multi_histogram(iris, 'Sepal.Width', 'Species')

The extra parameter in plot_multi_histogram is the name of the column containing the category labels.

We can see this more dramatically by creating a dataframe with many different distribution means:

a <-data.frame(n=rnorm(1000, mean = 1), category=rep('A', 1000))
b <-data.frame(n=rnorm(1000, mean = 2), category=rep('B', 1000))
c <-data.frame(n=rnorm(1000, mean = 3), category=rep('C', 1000))
d <-data.frame(n=rnorm(1000, mean = 4), category=rep('D', 1000))
e <-data.frame(n=rnorm(1000, mean = 5), category=rep('E', 1000))
f <-data.frame(n=rnorm(1000, mean = 6), category=rep('F', 1000))
many_distros <- do.call('rbind', list(a,b,c,d,e,f))

Passing data frame in as before (and widening chart using options):

options(repr.plot.width = 20, repr.plot.height = 8)
plot_multi_histogram(many_distros, 'n', 'category')

With the help of a temporary item class

public class item
{
    [XmlAttribute]
    public int id;
    [XmlAttribute]
    public string value;
}

Sample Dictionary:

Dictionary<int, string> dict = new Dictionary<int, string>()
{
    {1,"one"}, {2,"two"}
};

.

XmlSerializer serializer = new XmlSerializer(typeof(item[]), 
                                 new XmlRootAttribute() { ElementName = "items" });

Serialization

serializer.Serialize(stream, 
              dict.Select(kv=>new item(){id = kv.Key,value=kv.Value}).ToArray() );

Deserialization

var orgDict = ((item[])serializer.Deserialize(stream))
               .ToDictionary(i => i.id, i => i.value);

------------------------------------------------------------------------------

Here is how it can be done using XElement, if you change your mind.

Serialization

XElement xElem = new XElement(
                    "items",
                    dict.Select(x => new XElement("item",new XAttribute("id", x.Key),new XAttribute("value", x.Value)))
                 );
var xml = xElem.ToString(); //xElem.Save(...);

Deserialization

XElement xElem2 = XElement.Parse(xml); //XElement.Load(...)
var newDict = xElem2.Descendants("item")
                    .ToDictionary(x => (int)x.Attribute("id"), x => (string)x.Attribute("value"));

To literally fix your example you would use this:

Sub Normalize()


    Dim Ticker As Range
    Sheets("Sheet1").Activate
    Set Ticker = Range(Cells(2, 1), Cells(65, 1))
    Ticker.Copy

    Sheets("Sheet2").Select
    Cells(1, 1).PasteSpecial xlPasteAll



End Sub

To Make slight improvments on it would be to get rid of the Select and Activates:

Sub Normalize()
    With Sheets("Sheet1")
        .Range(.Cells(2, 1), .Cells(65, 1)).Copy Sheets("Sheet2").Cells(1, 1)
    End With
End Sub

but using the clipboard takes time and resources so the best way would be to avoid a copy and paste and just set the values equal to what you want.

Sub Normalize()
Dim CopyFrom As Range

Set CopyFrom = Sheets("Sheet1").Range("A2", [A65])
Sheets("Sheet2").Range("A1").Resize(CopyFrom.Rows.Count).Value = CopyFrom.Value

End Sub

To define the CopyFrom you can use anything you want to define the range, You could use Range("A2:A65"), Range("A2",[A65]), Range("A2", "A65") all would be valid entries. also if the A2:A65 Will never change the code could be further simplified to:

Sub Normalize()

Sheets("Sheet2").Range("A1:A65").Value = Sheets("Sheet1").Range("A2:A66").Value

End Sub

I added the Copy from range, and the Resize property to make it slightly more dynamic in case you had other ranges you wanted to use in the future.

Try following, which will convert convert single and double digit numbers to 3 digit numbers by prefixing zeros.

var base_number = 2;
var zero_prefixed_string = ("000" + base_number).slice(-3);

On Windows (IIS) in order to be able to SET GLOBAL time_zone = 'Europe/Helsinki' (or whatever) the MySQL time_zone description tables need to be populated first.

I downloaded these from this link https://dev.mysql.com/downloads/timezones.html

After running the downloaded SQL query I was able to set the GLOBAL time_zone and resolve the issue I had where SELECT NOW(); was returning GMT rather than BST.

According to Bootstrap 4 docs:

Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript.

E.g:

$('#idOfMyModal').on('shown.bs.modal', function () {
    $('input:first').trigger('focus')
});

What also works well is the SuppressWithNearbyCommentFilter which uses individual comments to suppress audit events.

For example

// CHECKSTYLE IGNORE check FOR NEXT 1 LINES
public void onClick(View view) { ... }

To configure a filter so that CHECKSTYLE IGNORE check FOR NEXT var LINES avoids triggering any audits for the given check for the current line and the next var lines (for a total of var+1 lines):

<module name="SuppressWithNearbyCommentFilter">
    <property name="commentFormat" value="CHECKSTYLE IGNORE (\w+) FOR NEXT (\d+) LINES"/>
    <property name="checkFormat" value="$1"/>
    <property name="influenceFormat" value="$2"/>
</module>

This limitation affected me when I tried to overload operators for generic types; since there was no "INumeric" constraint, and for a bevy of other reasons the good people on stackoverflow are happy to provide, operations cannot be defined on generic types.

I wanted something like

public struct Foo<T>
{
    public T Value{ get; private set; }

    public static Foo<T> operator +(Foo<T> LHS, Foo<T> RHS)
    {
        return new Foo<T> { Value = LHS.Value + RHS.Value; };
    }
}

I have worked around this issue using .net4 dynamic runtime typing.

public struct Foo<T>
{
    public T Value { get; private set; }

    public static Foo<T> operator +(Foo<T> LHS, Foo<T> RHS)
    {
        return new Foo<T> { Value = LHS.Value + (dynamic)RHS.Value };
    }
}

The two things about using dynamic are

1. Performance. All value types get boxed.
2. Runtime errors. You "beat" the compiler, but lose type safety. If the generic type doesn't have the operator defined, an exception will be thrown during execution.

BehaviorSubject keeps in memory the last value that was emitted by the observable. A regular Subject doesn't.

BehaviorSubject is like ReplaySubject with a buffer size of 1.

Use setFinishOnTouchOutside(false) for API > 11 and don't worry because its android's default behavior that activity themed dialog won't get finished on outside touch for API < 11 :) !!Cheerss!!

It seems people mix a content encoding with a built files/resources encoding. Having only maven properties is not enough. Having -Dfile.encoding=UTF8 not effective. To avoid having issues with encoding you should follow the following simple rules

1. Set maven encoding, as described above:

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

2. Always set encoding explicitly, when work with files, strings, IO in your code. If you do not follow this rule, your application depend on the environment. The -Dfile.encoding=UTF8 exactly is responsible for run-time environment configuration, but we should not depend on it. If you have thousands of clients, it takes more effort to configure systems and to find issues because of it. You just have an additional dependency on it which you can avoid by setting it explicitly. Most methods in Java that use a default encoding are marked as deprecated because of it.

3. Make sure the content, you are working with, also is in the same encoding, that you expect. If it is not, the previous steps do not matter! For instance a file will not be processed correctly, if its encoding is not UTF8 but you expect it. To check file encoding on Linux:

$ file --mime F_PRDAUFT.dsv

4. Force clients/server set encoding explicitly in requests/responses, here are examples:

@Produces("application/json; charset=UTF-8")
@Consumes("application/json; charset=UTF-8")

Hope this will be useful to someone.

try this one out.

<label for="user">user</label>
<input type="text" name="user" 
onfocus="if(this.value==this.defaultValue)this.value=''"    
onblur="if(this.value=='')this.value=this.defaultValue" 
value="username" maxlength="19" />

hope this helps.

This is the easiest way I have found to download multiple files.

$('body').on('click','.download_btn',function(){
    downloadFiles([
        ['File1.pdf', 'File1-link-here'],
        ['File2.pdf', 'File2-link-here'],
        ['File3.pdf', 'File3-link-here'],
        ['File4.pdf', 'File4-link-here']
    ]);
})
function downloadFiles(files){
    if(files.length == 0){
        return;
    }
    file = files.pop();
    var Link = $('body').append('<a href="'+file[1]+'" download="file[0]"></a>');
    Link[0].click(); 
    Link.remove();
    downloadFiles(files);
}

This should be work for you. Thank You.

The most general difference between procedures and functions is that they are invoked differently and for different purposes:

1. A procedure does not return a value. Instead, it is invoked with a CALL statement to perform an operation such as modifying a table or processing retrieved records.
2. A function is invoked within an expression and returns a single value directly to the caller to be used in the expression.
3. You cannot invoke a function with a CALL statement, nor can you invoke a procedure in an expression.

Syntax for routine creation differs somewhat for procedures and functions:

1. Procedure parameters can be defined as input-only, output-only, or both. This means that a procedure can pass values back to the caller by using output parameters. These values can be accessed in statements that follow the CALL statement. Functions have only input parameters. As a result, although both procedures and functions can have parameters, procedure parameter declaration differs from that for functions.

2. Functions return value, so there must be a RETURNS clause in a function definition to indicate the data type of the return value. Also, there must be at least one RETURN statement within the function body to return a value to the caller. RETURNS and RETURN do not appear in procedure definitions.

   • To invoke a stored procedure, use the CALL statement. To invoke a stored function, refer to it in an expression. The function returns a value during expression evaluation.

   • A procedure is invoked using a CALL statement, and can only pass back values using output variables. A function can be called from inside a statement just like any other function (that is, by invoking the function's name), and can return a scalar value.

   • Specifying a parameter as IN, OUT, or INOUT is valid only for a PROCEDURE. For a FUNCTION, parameters are always regarded as IN parameters.

   If no keyword is given before a parameter name, it is an IN parameter by default. Parameters for stored functions are not preceded by IN, OUT, or INOUT. All function parameters are treated as IN parameters.

To define a stored procedure or function, use CREATE PROCEDURE or CREATE FUNCTION respectively:

CREATE PROCEDURE proc_name ([parameters])
 [characteristics]
 routine_body


CREATE FUNCTION func_name ([parameters])
 RETURNS data_type       // diffrent
 [characteristics]
 routine_body

A MySQL extension for stored procedure (not functions) is that a procedure can generate a result set, or even multiple result sets, which the caller processes the same way as the result of a SELECT statement. However, the contents of such result sets cannot be used directly in expression.

Stored routines (referring to both stored procedures and stored functions) are associated with a particular database, just like tables or views. When you drop a database, any stored routines in the database are also dropped.

Stored procedures and functions do not share the same namespace. It is possible to have a procedure and a function with the same name in a database.

In Stored procedures dynamic SQL can be used but not in functions or triggers.

SQL prepared statements (PREPARE, EXECUTE, DEALLOCATE PREPARE) can be used in stored procedures, but not stored functions or triggers. Thus, stored functions and triggers cannot use Dynamic SQL (where you construct statements as strings and then execute them). (Dynamic SQL in MySQL stored routines)

Some more interesting differences between FUNCTION and STORED PROCEDURE:

1. (This point is copied from a blogpost.) Stored procedure is precompiled execution plan where as functions are not. Function Parsed and compiled at runtime. Stored procedures, Stored as a pseudo-code in database i.e. compiled form.

2. (I'm not sure for this point.)
   Stored procedure has the security and reduces the network traffic and also we can call stored procedure in any no. of applications at a time. reference

3. Functions are normally used for computations where as procedures are normally used for executing business logic.

4. Functions Cannot affect the state of database (Statements that do explicit or implicit commit or rollback are disallowed in function) Whereas Stored procedures Can affect the state of database using commit etc.
   refrence: J.1. Restrictions on Stored Routines and Triggers

5. Functions can't use FLUSH statements whereas Stored procedures can do.

6. Stored functions cannot be recursive Whereas Stored procedures can be. Note: Recursive stored procedures are disabled by default, but can be enabled on the server by setting the max_sp_recursion_depth server system variable to a nonzero value. See Section 5.2.3, “System Variables”, for more information.

7. Within a stored function or trigger, it is not permitted to modify a table that is already being used (for reading or writing) by the statement that invoked the function or trigger. Good Example: How to Update same table on deletion in MYSQL?

Note: that although some restrictions normally apply to stored functions and triggers but not to stored procedures, those restrictions do apply to stored procedures if they are invoked from within a stored function or trigger. For example, although you can use FLUSH in a stored procedure, such a stored procedure cannot be called from a stored function or trigger.

Simply PROJECTION deals with elimination or selection of columns, while SELECTION deals with elimination or selection of rows.

Since Enum Type implements IConvertible interface, a better implementation should be something like this:

public T GetEnumFromString<T>(string value) where T : struct, IConvertible
{
   if (!typeof(T).IsEnum) 
   {
      throw new ArgumentException("T must be an enumerated type");
   }

   //...
}

This will still permit passing of value types implementing IConvertible. The chances are rare though.

The correct answer is to use Environment.NewLine, as you've noted. It is environment specific and provides clarity over "\r\n" (but in reality makes no difference).

foreach (var item in FirmNameList) 
{
    if (FirmNames != "")
    {
        FirmNames += ", " + Environment.NewLine;
    }
    FirmNames += item; 
} 

Guessing from the tag 'operand' you want to check a value?

$myValue = 5;
$minValue = 1;
$maxValue = 10;

if ($myValue >= $minValue && $myValue <= $maxValue) { 
  //do something
}

The docker documentation (and self-explanation) makes a distinction between "virtual machines" vs. "containers". They have the tendency to interpret and use things in a little bit uncommon ways. They can do that because it is up to them, what do they write in their documentation, and because the terminology for virtualization is not yet really exact.

Fact is what the Docker documentation understands on "containers", is paravirtualization (sometimes "OS-Level virtualization") in the reality, contrarily the hardware virtualization, which is docker not.

Docker is a low quality paravirtualisation solution. The container vs. VM distinction is invented by the docker development, to explain the serious disadvantages of their product.

The reason, why it became so popular, is that they "gave the fire to the ordinary people", i.e. it made possible the simple usage of typically server ( = Linux) environments / software products on Win10 workstations. This is also a reason for us to tolerate their little "nuance". But it does not mean that we should also believe it.

The situation is made yet more cloudy by the fact that docker on Windows hosts used an embedded Linux in HyperV, and its containers have run in that. Thus, docker on Windows uses a combined hardware and paravirtualization solution.

In short, Docker containers are low-quality (para)virtual machines with a huge advantage and a lot of disadvantages.

You can't have two elements with the same ID.

Aside from that, you are defining them as block elemnts, meaning (in layman's terms) that they are being forced to appear on their own line.

Instead, try something like this:

<div class="link"><a href="..."><img src="..."... /></a></div>
<div class="link"><a href="..."><img src="..."... /></a></div>

CSS:

.link {
    width: 50%;
    float: left;
    text-align: center;
}

To reset window scroll back to top, $(window).scrollTop(0) in the beforeunload event does the tricks, however, I tested in Chrome 80 it will go back to the old location after the reload.

To prevent that, set the history.scrollRestoration to "manual".

//Reset scroll top

history.scrollRestoration = "manual";

$(window).on('beforeunload', function(){
      $(window).scrollTop(0);
});

REGEXP_COUNT should do the trick:

select REGEXP_COUNT('123-345-566', '-') from dual;

This is to do with JavaScript's + in operator - if a number and a string are "added" up, the number is converted into a string:

0 + 1; //1
'0' + 1; // '01'

To solve this, use the + unary operator, or use parseInt():

+'0' + 1; // 1
parseInt('0', 10) + 1; // 1

The unary + operator converts it into a number (however if it's a decimal it will retain the decimal places), and parseInt() is self-explanatory (converts into number, ignoring decimal places).

The second argument is necessary for parseInt() to use the correct base when leading 0s are placed:

parseInt('010'); // 8 in older browsers, 10 in newer browsers
parseInt('010', 10); // always 10 no matter what

There's also parseFloat() if you need to convert decimals in strings to their numeric value - + can do that too but it behaves slightly differently: that's another story though.

Use -1 index (negative indices count backward from the end of the array):

a[-1] # => 5
b[-1] # => 6

or Array#last method:

a.last # => 5
b.last # => 6

Steps for Windows 7:

1. Ensure that the php.ini file that the PHP engine uses is the one you think it is.
2. Ensure extension_dir in php.ini is correctly set to the ext folder
3. Ensure extension=php_curl.dll in the php.ini is uncommented

Finally and maybe the one most people don't know: 4. Ensure that there are these two files in the Windows System32 folder: libeay32.dll ssleay32.dll If not there, you may copy these two files from the php folder.

For ASP.NET MVC, we successfully save a form with checkboxes via an AJAX POST with the following, which is a combination of several methods referenced in this post, including @Jecoms suggestion:

var form = $('#myForm');
// Serialize the form into a JavaScript object using the jQuery.serializeObject plugin
// https://plugins.jquery.com/serializeObject/
var data = form.serializeObject();
// Change the submitted value of checkboxes to the value of the checked property
$('#myForm input[type=checkbox]').each( function () { data[this.name] = this.checked; } );
// For a MVC controller, convert the JS object back into a query string using jQuery.param function
data = $.param(data);
// Perform AJAX POST with the form data
$.ajax({
    async: true,
    url: 'mvcActionMethodURL',
    type: 'POST',
    data: data,
    success: function (data, textStatus, xhr) {

    },
    error: function (xhr, status, error) {

    }
});

SELECT COUNT(*), table1.category_id, table2.category_name 
FROM table1 
INNER JOIN table2 ON table1.category_id=table2.category_id 
WHERE table1.colour <> 'red'
GROUP BY table1.category_id, table2.category_name 

Save your button in a strong outlet (let's call it myButton) and do this to add/remove it:

// Get the reference to the current toolbar buttons
NSMutableArray *toolbarButtons = [self.toolbarItems mutableCopy];

// This is how you remove the button from the toolbar and animate it
[toolbarButtons removeObject:self.myButton];
[self setToolbarItems:toolbarButtons animated:YES];

// This is how you add the button to the toolbar and animate it
if (![toolbarButtons containsObject:self.myButton]) {
    // The following line adds the object to the end of the array.  
    // If you want to add the button somewhere else, use the `insertObject:atIndex:` 
    // method instead of the `addObject` method.
    [toolbarButtons addObject:self.myButton];
    [self setToolbarItems:toolbarButtons animated:YES];
}

Because it is stored in the outlet, you will keep a reference to it even when it isn't on the toolbar.

In java, String is immutable. Being immutable we mean that once a String is created, we can not change its value. StringBuffer is mutable. Once a StringBuffer object is created, we just append the content to the value of object instead of creating a new object. StringBuilder is similar to StringBuffer but it is not thread-safe. Methods of StingBuilder are not synchronized but in comparison to other Strings, the Stringbuilder runs fastest. You can learn difference between String, StringBuilder and StringBuffer by implementing them.

Google has updated the Virtual Device targeting API 23. It now comes with Google Play Services 9.0.80. So if you are using Google Maps API V 2.0 (I'm using play-services-maps:9.0.0 and play-services-location.9.0.0) no workaround necessary. It just works!

This script searches for non-ascii characters in one column. It generates a string of all valid characters, here code point 32 to 127. Then it searches for rows that don't match the list:

declare @str varchar(128)
declare @i int
set @str = ''
set @i = 32
while @i <= 127
    begin
    set @str = @str + '|' + char(@i)
    set @i = @i + 1
    end

select  col1
from    YourTable
where   col1 like '%[^' + @str + ']%' escape '|'

While most despise Flash, it is a viable option for providing "save" and "save as" functionality in your html/javascript environment.

Self-contained version that increases job security:

switch((s.match(r)||[null])[0])

function identifyCountry(hostname,only_gov=false){
    const exceptionRe = /^(?:uk|ac|eu)$/ ; //https://en.wikipedia.org/wiki/Country_code_top-level_domain#ASCII_ccTLDs_not_in_ISO_3166-1
    const h = hostname.split('.');

Honestly, though, you could just do something like

function switchableMatch(s,r){
    //returns the FIRST match of r on s; otherwise, null
    const m = s.match(r);
    if(m) return m[0];
    else return null;
}

and then later switch(switchableMatch(s,r)){…}

Particular example: use a BindingResult object as an argument for a validate method of a Validator inside a Controller.

Then, you can check this object looking for validation errors:

validator.validate(modelObject, bindingResult);  
if (bindingResult.hasErrors()) {  
    // do something  
}

The problem is where you are executing:

rankings[kvp.Key] = rankings[kvp.Key] + 4;

You cannot modify the collection you are iterating through in a foreach loop. A foreach loop requires the loop to be immutable during iteration.

Instead, use a standard 'for' loop or create a new loop that is a copy and iterate through that while updating your original.

If you're using ZLib in your project, then you need to find :

#if 1

in zconf.h and replace(uncomment) it with :

#if HAVE_UNISTD_H /* ...the rest of the line

If it isn't ZLib I guess you should find some alternative way to do this. GL.

for me it was a path issue when saving the image.

int count = Directory.EnumerateFiles(System.Web.HttpContext.Current.Server.MapPath("~/images/savedimages"), "*").Count();

var img = Base64ToImage(imgRaw);

string path = "images/savedimages/upImages" + (count + 1) + ".png";

img.Save(Path.Combine(System.Web.HttpContext.Current.Server.MapPath(path)));

return path;

So I fixed it by adding the following forward slash

String path = "images/savedimages....

should be

String path = "/images/savedimages....

Hope that helps anyone stuck!

Had need of this myself, so I wrote a String extension that both allows for URLEncoding strings, as well as the more common end goal, converting a parameter dictionary into "GET" style URL Parameters:

extension String {
    func URLEncodedString() -> String? {
        var escapedString = self.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
        return escapedString
    }
    static func queryStringFromParameters(parameters: Dictionary<String,String>) -> String? {
        if (parameters.count == 0)
        {
            return nil
        }
        var queryString : String? = nil
        for (key, value) in parameters {
            if let encodedKey = key.URLEncodedString() {
                if let encodedValue = value.URLEncodedString() {
                    if queryString == nil
                    {
                        queryString = "?"
                    }
                    else
                    {
                        queryString! += "&"
                    }
                    queryString! += encodedKey + "=" + encodedValue
                }
            }
        }
        return queryString
    }
}

Enjoy!

GET will send the data as a querystring, but POST will not. Rather it will send it in the body of the request.

Try to use JSONP in your Ajax call. It will bypass the Same Origin Policy.

http://learn.jquery.com/ajax/working-with-jsonp/

Try example

$.ajax({
    url: "https://api.dailymotion.com/video/x28j5hv?fields=title",

    dataType: "jsonp",
    success: function( response ) {
        console.log( response ); // server response
    }

});

Hi i also got this error when i use my online databases from godaddy server i think it has the mysql version of 5.1 or more. but when i do from my localhost server (version 5.7) it was fine after that i created the table from local server and copied to the online server using mysql yog i think the problem is with character set

Datatable JS plugin is also one good alternate to accomedate search feature for html table

var table = $('#example').DataTable();

// #myInput is a <input type="text"> element
$('#myInput').on( 'keyup', function () {
    table.search( this.value ).draw();
} );

Both void and null pointers point to a memory location in the end.

A null pointer points to place (in a memory segment) which is usually the 0th address of memory segment. It is almost all about how the underlying OS treat that "reserved" memory location (an implementation detail) when you try to access it to read/write or dereference. For example, that particular memory location can be marked as "non-accessible" and throws an expection when it's accessed.

A void pointer can point to anywhere and potentially represent any type (primitive, reference-type, and including null).

As someone nicely put above, null pointer represents a value whereas void* represents a type more than a value.

Let's dissect it. There are three parts:

1. cd -- This is change directory command.
2. /d -- This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0. (%~d0 Changs active drive, cd %~p0 change the directory).
3. %~dp0 -- This can be dissected further into three parts:
   1. %0 -- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 -- The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 -- The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.

I ran S.Lott's code and produced the same 10% performance increase by preallocating. I tried Ned Batchelder's idea using a generator and was able to see the performance of the generator better than that of the doAllocate. For my project the 10% improvement matters, so thanks to everyone as this helps a bunch.

def doAppend(size=10000):
    result = []
    for i in range(size):
        message = "some unique object %d" % ( i, )
        result.append(message)
    return result

def doAllocate(size=10000):
    result = size*[None]
    for i in range(size):
        message = "some unique object %d" % ( i, )
        result[i] = message
    return result

def doGen(size=10000):
    return list("some unique object %d" % ( i, ) for i in xrange(size))

size = 1000
@print_timing
def testAppend():
    for i in xrange(size):
        doAppend()

@print_timing
def testAlloc():
    for i in xrange(size):
        doAllocate()

@print_timing
def testGen():
    for i in xrange(size):
        doGen()


testAppend()
testAlloc()
testGen()

Output

testAppend took 14440.000ms
testAlloc took 13580.000ms
testGen took 13430.000ms

You need to convert your wildcard expression to a regular expression. For example:

    private bool WildcardMatch(String s, String wildcard, bool case_sensitive)
    {
        // Replace the * with an .* and the ? with a dot. Put ^ at the
        // beginning and a $ at the end
        String pattern = "^" + Regex.Escape(wildcard).Replace(@"\*", ".*").Replace(@"\?", ".") + "$";

        // Now, run the Regex as you already know
        Regex regex;
        if(case_sensitive)
            regex = new Regex(pattern);
        else
            regex = new Regex(pattern, RegexOptions.IgnoreCase);

        return(regex.IsMatch(s));
    } 

One option for the foreach loop is:

StringBuilder sb = new StringBuilder();
for(String s:list){
  if (sb.length()>0) sb.append(",");
  sb.append(s);
}

Sometimes in Windows whitespaces in paths are not recognized correctly

If you have a path problem and path seems like

c:\Program Files\....

try changing it in an old DOS format like

"C:\Progra~1\...

You can use dir /x to check correct syntax (third column)

C:\>dir /x ... 11.01.2008 15:47 <DIR> DOCUME~1 Documents and Settings 01.12.2006 09:10 <DIR> MYPROJ~1 My Projects 21.01.2011 14:08 <DIR> PROGRA~1 Program Files ...

In my pc JAVA_HOME is (and it works)

"C:\Progra~1\Java\jdk1.8.0_121"

Tested in Windows 10

Give it a display:inline-block in CSS - that should let it do what you want.
In terms of compatibility: IE6/7 will work with this, as quirks mode suggests:

IE 6/7 accepts the value only on elements with a natural display: inline.

I got around it by wrapping the supplied runnable submitted to the executor.

CompletableFuture.runAsync(() -> {
        try {
              runnable.run();
        } catch (Throwable e) {
              Log.info(Concurrency.class, "runAsync", e);
        }
}, executorService);

The new command to flush the privileges is:

FLUSH PRIVILEGES

The old command FLUSH ALL PRIVILEGES does not work any more.

You will get an error that looks like that:

MariaDB [(none)]> FLUSH ALL PRIVILEGES; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ALL PRIVILEGES' at line 1

Hope this helps :)

When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[]
For example:
if your radio button is:

<input type="radio" name="rdb" value="male"/>

then in your php code you need to use:

$rdb_value = $_POST['rdb'];

Because it appends an element to a list? Push is usually used when referring to stacks.

These are my rules of thumb:

If default values can be calculated from other parameters, use default expressions as in:

fun <- function(x,levels=levels(x)){
    blah blah blah
}

if otherwise using missing

fun <- function(x,levels){
    if(missing(levels)){
        [calculate levels here]
    }
    blah blah blah
}

In the rare case that you thing a user may want to specify a default value that lasts an entire R session, use getOption

fun <- function(x,y=getOption('fun.y','initialDefault')){# or getOption('pkg.fun.y',defaultValue)
    blah blah blah
}

If some parameters apply depending on the class of the first argument, use an S3 generic:

fun <- function(...)
    UseMethod(...)


fun.character <- function(x,y,z){# y and z only apply when x is character
   blah blah blah 
}

fun.numeric <- function(x,a,b){# a and b only apply when x is numeric
   blah blah blah 
}

fun.default <- function(x,m,n){# otherwise arguments m and n apply
   blah blah blah 
}

Use ... only when you are passing additional parameters on to another function

cat0 <- function(...)
    cat(...,sep = '')

Finally, if you do choose the use ... without passing the dots onto another function, warn the user that your function is ignoring any unused parameters since it can be very confusing otherwise:

fun <- (x,...){
    params <- list(...)
    optionalParamNames <- letters
    unusedParams <- setdiff(names(params),optionalParamNames)
    if(length(unusedParams))
        stop('unused parameters',paste(unusedParams,collapse = ', '))
   blah blah blah 
}

I am now returning to setters and getters but I am also putting the getters and setters in the magic methos __get and __set. This way I have a default behavior when I do this

$class->var;

This will just call the getter I have set in the __get. Normally I will just use the getter directly but there are still some instances where this is just simpler.

Use TO_TIMESTAMP function

TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')

You could make those submit buttons and inside the servlet your are submitting the form to you could test the name of the button which was pressed and render the corresponding jsp page.

<input type="submit" value="Creazione Nuovo Corso" name="CreateCourse" />
<input type="submit" value="Gestione Autorizzazioni" name="AuthorizationManager" />

Inside the TrainerMenu servlet if request.getParameter("CreateCourse") is not empty then the first button was clicked and you could render the corresponding jsp.

Changing the width of the container also fixes it rather than changing the width and height of source file.

.SvgImage img{ width:80%; }

This fixes my issue of re sizing svg . you can give any % based on your requirement.

You can disable dragging simply by using draggable="false" attribute.

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

The correct parameter to set the maximum length is:

SET @@group_concat_max_len = value_numeric;

value_numeric must be > 1024; by default the group_concat_max_len value is 1024.

I had the same issue and eventually chose to use a Rectangle element:

<Rectangle HorizontalAlignment="Stretch" Fill="Blue" Height="4"/>

In my opinion it's somewhat easier to modify/shape than a separator. Of course the Separator is a very easy and neat solution for simple separations :)

I built on a previous answer and have this, some extra padding just to be able to conveniently join all the output:

SELECT 
CONCAT('SELECT ''',A.TABLE_NAME, '-' ,A.COLUMN_NAME,''' FROM ', A.TABLE_SCHEMA, '.', A.TABLE_NAME, 
       ' WHERE ', A.COLUMN_NAME, ' LIKE \'%Value%\' UNION')
FROM INFORMATION_SCHEMA.COLUMNS A
WHERE 
        A.TABLE_SCHEMA != 'mysql' 
AND     A.TABLE_SCHEMA != 'innodb' 
AND     A.TABLE_SCHEMA != 'performance_schema' 
AND     A.TABLE_SCHEMA != 'information_schema'
UNION SELECT 'SELECT '''

-- for exact match use: A.COLUMN_NAME, ' LIKE \'Value\' instead

First you run this, then paste in and run the result (no editing) and it will display all the table names and columns where the value is used.

You can use cvResize. Or better use c++ interface (eg cv::Mat instead of IplImage and cv::imread instead of cvLoadImage) and then use cv::resize which handles memory allocation and deallocation itself.

You need to use absolutely-positioned CSS over a relatively-positioned img tag. The article Text Blocks Over Image gives a step-by-step example for placing text over an image.

There are multiple ways:

• String.valueOf(number) (my preference)
• "" + number (I don't know how the compiler handles it, perhaps it is as efficient as the above)
• Integer.toString(number)

Using Helper class you can access SQLite Database and can perform the various operations on it by overriding the onCreate() and onUpgrade() methods.

http://technologyguid.com/android-sqlite-database-app-example/

For what it's worth, here is my way:

List<string> list = new List<string>(new string[] { "cat", "Dog", "parrot", "dog", "parrot", "goat", "parrot", "horse", "goat" });
Dictionary<string, int> wordCount = new Dictionary<string, int>();

//count them all:
list.ForEach(word =>
{
    string key = word.ToLower();
    if (!wordCount.ContainsKey(key))
        wordCount.Add(key, 0);
    wordCount[key]++;
});

//remove words appearing only once:
wordCount.Keys.ToList().FindAll(word => wordCount[word] == 1).ForEach(key => wordCount.Remove(key));

Console.WriteLine(string.Format("Found {0} duplicates in the list:", wordCount.Count));
wordCount.Keys.ToList().ForEach(key => Console.WriteLine(string.Format("{0} appears {1} times", key, wordCount[key])));

If by mistake, you have deleted your Tomcat Server and Eclipse is not showing more options (Next button will be inactive) then in this case follow the bellow steps:

1. First remove the two files from the following path:

   • Path : workspace/.metadata/.plugins/org.eclipse.runtime/.settings/

   • And that two files are :

     1. org.eclipse.wst.server.core.prefs
     2. org.eclipse.jst/server.tomcat.core.prefs

   • After deleting/removing the above two files from the workspace, Restart the Eclipse IDE.

   • Change to the Server View, Right Click 'New', Window 'Define a New Server' is shown, --> Select the Apache Folder, choose Tomcat-Version

   • Browse to the unzipped 'Apache-Tomcat folder', choose the second level

   • Now you are able to add/configure your new Tomcat Server. (Now you will see the 'Next' button will become active, and you can then follow the normal instructions)

In intellij8 I was using a specific plugin "Jar Tool" that is configurable and allows to pack a JAR archive.

out: dict_values([{1:a, 2:b}])

in:  str(dict.values())[14:-3]    
out: 1:a, 2:b

Purely for visual purposes. Does not produce a useful product... Only useful if you want a long dictionary to print in a paragraph type form.

With JavaScript you can create a link 'on the fly' using something like:

var mail = document.createElement("a");
mail.href = "mailto:[email protected]";
mail.click();

This is redirected by the browser to some mail client installed on the machine without losing the content of the current window ... and you would not need any API like 'jQuery'.

In the beginning there was sh, sed, and awk (and find, and grep, and...). It was good. But awk can be an odd little beast and hard to remember if you don't use it often. Then the great camel created Perl. Perl was a system administrator's dream. It was like shell scripting on steroids. Text processing, including regular expressions were just part of the language. Then it got ugly... People tried to make big applications with Perl. Now, don't get me wrong, Perl can be an application, but it can (can!) look like a mess if you're not really careful. Then there is all this flat data business. It's enough to drive a programmer nuts.

Enter Python, Ruby, et al. These are really very good general purpose languages. They support text processing, and do it well (though perhaps not as tightly entwined in the basic core of the language). But they also scale up very well, and still have nice looking code at the end of the day. They also have developed pretty hefty communities with plenty of libraries for most anything.

Now, much of the negativeness towards Perl is a matter of opinion, and certainly some people can write very clean Perl, but with this many people complaining about it being too easy to create obfuscated code, you know some grain of truth is there. The question really becomes then, are you ever going to use this language for more than simple bash script replacements. If not, learn some more Perl.. it is absolutely fantastic for that. If, on the other hand, you want a language that will grow with you as you want to do more, may I suggest Python or Ruby.

Either way, good luck!

Sorry for delay, but I will try to make perfect form :)

I will added Count validation steps and check every time not .val(). Check .length, because I think is better pattern in your case. Of course remove unbind function.

My jsFiddle

Of course source code:

// Prevent form submit if any entrees are missing
$('form').submit(function(e){

    e.preventDefault();

    var formIsValid = true;

    // Count validation steps
    var validationLoop = 0;

    // Cycle through each Attendee Name
    $('[name="atendeename[]"]', this).each(function(index, el){

        // If there is a value
        if ($(el).val().length > 0) {
            validationLoop++;

            // Find adjacent entree input
            var entree = $(el).next('input');

            var entreeValue = entree.val();

            // If entree is empty, don't submit form
            if (entreeValue.length === 0) {
                alert('Please select an entree');
                entree.focus();
                formIsValid = false;
                return false;
            }

        }

    });

    if (formIsValid && validationLoop > 0) {
        alert("Correct Form");
        return true;
    } else {
        return false;
    }

});

I use .h because that's what Microsoft uses, and what their code generator creates. No need to go against the grain.

Here's a Sass mixin (scss) for those interested. Compass/CSS 3 doesn't seem to have a user-select mixin.

// @usage use within a rule
// ex. img {@include user-select(none);}
// @param assumed valid user-select value
@mixin user-select($value)
{
    & {
        -webkit-touch-callout: $value;
        -webkit-user-select: $value;
        -khtml-user-select: $value;
        -moz-user-select: $value;
        -ms-user-select: $value;
        user-select: $value;
    }
}

Though Compass would do it in a more robust way, i.e. only add support for vendors you've chosen.

As Kintaro already says, person is a method (because of def) and always returns a new Person instance. As you found out it would work if you change the method to a var or val:

val person = new Person("Kumar",12)

Another possibility would be:

def person = new Person("Kumar",12)
val p = person
p.age=20
println(p.age)

However, person.age=20 in your code is allowed, as you get back a Person instance from the person method, and on this instance you are allowed to change the value of a var. The problem is, that after that line you have no more reference to that instance (as every call to person will produce a new instance).

This is nothing special, you would have exactly the same behavior in Java:

class Person{ 
   public int age; 
   private String name;
   public Person(String name; int age) {
      this.name = name;  
      this.age = age;
   }
   public String name(){ return name; }
}

public Person person() { 
  return new Person("Kumar", 12); 
}

person().age = 20;
System.out.println(person().age); //--> 12

(Edit: Forget my previous babble...)

Ok, there might be situations where you would go either to the model or to some other url... But I don't really think this belongs in the model, the view (or maybe the model) sounds more apropriate.

About the routes, as far as I know the routes is for the actions in controllers (wich usually "magically" uses a view), not directly to views. The controller should handle all requests, the view should present the results and the model should handle the data and serve it to the view or controller. I've heard a lot of people here talking about routes to models (to the point I'm allmost starting to beleave it), but as I understand it: routes goes to controllers. Of course a lot of controllers are controllers for one model and is often called <modelname>sController (e.g. "UsersController" is the controller of the model "User").

If you find yourself writing nasty amounts of logic in a view, try to move the logic somewhere more appropriate; request and internal communication logic probably belongs in the controller, data related logic may be placed in the model (but not display logic, which includes link tags etc.) and logic that is purely display related would be placed in a helper.

If you look under the hood the QueryString property is a NameValueCollection. When I've done similar things I've usually been interested in serialising AND deserialising so my suggestion is to build a NameValueCollection up and then pass to:

using System.Linq;
using System.Web;
using System.Collections.Specialized;

private string ToQueryString(NameValueCollection nvc)
{
    var array = (
        from key in nvc.AllKeys
        from value in nvc.GetValues(key)
            select string.Format(
                "{0}={1}",
                HttpUtility.UrlEncode(key),
                HttpUtility.UrlEncode(value))
        ).ToArray();
    return "?" + string.Join("&", array);
}

I imagine there's a super elegant way to do this in LINQ too...

In App.Xaml.Cs:

MainPage = new NavigationPage( new YourPage());

When you wish to navigate from YourPage to the next page you do:

await Navigation.PushAsync(new YourSecondPage());

You can read more about Xamarin Forms navigation here: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/navigation/hierarchical

Microsoft has quite good docs on this.

There is also the newer concept of the Shell. It allows for a new way of structuring your application and simplifies navigation in some cases.

Please remove e.preventDefault(), because event.cancelable of touchmove is false. So you can't call this method.

Bearer token is one or more repetition of alphabet, digit, "-" , "." , "_" , "~" , "+" , "/" followed by 0 or more "=".

RFC 6750 2.1. Authorization Request Header Field (Format is ABNF (Augmented BNF))

The syntax for Bearer credentials is as follows:

     b64token    = 1*( ALPHA / DIGIT /
                       "-" / "." / "_" / "~" / "+" / "/" ) *"="
     credentials = "Bearer" 1*SP b64token

It looks like Base64 but according to Should the token in the header be base64 encoded?, it is not.

Digging a bit deeper in to "HTTP/1.1, part 7: Authentication"**, however, I see that b64token is just an ABNF syntax definition allowing for characters typically used in base64, base64url, etc.. So the b64token doesn't define any encoding or decoding but rather just defines what characters can be used in the part of the Authorization header that will contain the access token.

This fully addresses the first 3 items in the OP question's list. So I'm extending this answer to address the 4th question, about whether the token must be validated, so @mon feel free to remove or edit:

The authorizer is responsible for accepting or rejecting the http request. If the authorizer says the token is valid, it's up to you to decide what this means:

• Does the authorizer have a way of inspecting the URL, identifying the operation, and looking up some role-based access control database to see if it is allowed? If yes and the request comes through, the service can assume it is allowed, and does not need to verify.
• Is the token an all-or-nothing, so if the token is correct, all operations are allowed? Then the service doesn't need to verify.
• Does the token mean "this request is allowed, but here is the UUID for the role, you check whether the operation is allowed". Then it's up to the service to look up that role, and see if the operation is allowed.

Create a new directory layout-land, then create xml file with same name in layout-land as it was layout directory and align there your content for Landscape mode.

Note that id of content in both xml is same.

This is more complicated if you have a nested MasterPage. You need to first find the content control that contains the nested MasterPage, and then find the control on your nested MasterPage from that.

Crucial bit: Master.Master.

See here: http://forums.asp.net/t/1059255.aspx?Nested+master+pages+and+Master+FindControl

Example:

'Find the content control

Dim ct As ContentPlaceHolder = Me.Master.Master.FindControl("cphMain")

'now find controls inside that content

Dim lbtnSave As LinkButton = ct.FindControl("lbtnSave")

You could try powershell. There are get-content and set-content commandlets build in that you could use.

This solution works in all major browsers:

saveSelection() is attached to the onmouseup and onkeyup events of the div and saves the selection to the variable savedRange.

restoreSelection() is attached to the onfocus event of the div and reselects the selection saved in savedRange.

This works perfectly unless you want the selection to be restored when the user clicks the div aswell (which is a bit unintuitative as normally you expect the cursor to go where you click but code included for completeness)

To achieve this the onclick and onmousedown events are canceled by the function cancelEvent() which is a cross browser function to cancel the event. The cancelEvent() function also runs the restoreSelection() function because as the click event is cancelled the div doesn't receive focus and therefore nothing is selected at all unless this functions is run.

The variable isInFocus stores whether it is in focus and is changed to "false" onblur and "true" onfocus. This allows click events to be cancelled only if the div is not in focus (otherwise you would not be able to change the selection at all).

If you wish to the selection to be change when the div is focused by a click, and not restore the selection onclick (and only when focus is given to the element programtically using document.getElementById("area").focus(); or similar then simply remove the onclick and onmousedown events. The onblur event and the onDivBlur() and cancelEvent() functions can also safely be removed in these circumstances.

This code should work if dropped directly into the body of an html page if you want to test it quickly:

<div id="area" style="width:300px;height:300px;" onblur="onDivBlur();" onmousedown="return cancelEvent(event);" onclick="return cancelEvent(event);" contentEditable="true" onmouseup="saveSelection();" onkeyup="saveSelection();" onfocus="restoreSelection();"></div>
<script type="text/javascript">

function saveSelection()
{
    if(window.getSelection)//non IE Browsers
    {
        savedRange = window.getSelection().getRangeAt(0);
    }
    else if(document.selection)//IE
    { 
        savedRange = document.selection.createRange();  
    } 
}

function restoreSelection()
{
    isInFocus = true;
    document.getElementById("area").focus();
    if (savedRange != null) {
        if (window.getSelection)//non IE and there is already a selection
        {
            var s = window.getSelection();
            if (s.rangeCount > 0) 
                s.removeAllRanges();
            s.addRange(savedRange);
        }
        else if (document.createRange)//non IE and no selection
        {
            window.getSelection().addRange(savedRange);
        }
        else if (document.selection)//IE
        {
            savedRange.select();
        }
    }
}
//this part onwards is only needed if you want to restore selection onclick
var isInFocus = false;
function onDivBlur()
{
    isInFocus = false;
}

function cancelEvent(e)
{
    if (isInFocus == false && savedRange != null) {
        if (e && e.preventDefault) {
            //alert("FF");
            e.stopPropagation(); // DOM style (return false doesn't always work in FF)
            e.preventDefault();
        }

I just encountered this problem myself and found that Ubuntu 14.04 uses Upstart instead of Systemd, so systemctl commands will not work. This changed in 15.04, so one way around this would be to update your ubuntu install.

If this is not an option for you (it's not for me right now), you need to find the Upstart command that does what you need to do.

For enable, the generic looks to be the following:

update-rc.d <service> enable

Link to Ubuntu documentation: https://wiki.ubuntu.com/SystemdForUpstartUsers

and just FYI, in case you do all of your data reference checks and find no bad data...apparently it is not possible to create a foreign key constraint between two tables and fields where those fields are the primary key in both tables! Do not ask me how I know this.

The following code get the first day of January of current year (but it can be a another date) and add 365 days to that day (but it can be N number of days) using DateTime class and its method modify() and format():

echo (new DateTime((new DateTime())->modify('first day of January this year')->format('Y-m-d')))->modify('+365 days')->format('Y-m-d');

An activity populates the ActionBar in its onCreateOptionsMenu() method.

Instead of using setcustomview(), just override onCreateOptionsMenu like this:

@Override    
public boolean onCreateOptionsMenu(Menu menu) {
  MenuInflater inflater = getMenuInflater();
  inflater.inflate(R.menu.mainmenu, menu);
  return true;
}

If an actions in the ActionBar is selected, the onOptionsItemSelected() method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
    case R.id.menuitem1:
      Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
      break;
    case R.id.menuitem2:
      Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
      break;
  }
  return true;
}

Changed it to getElementById(myField)

 function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        document.getElementById(myField).focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    //MOZILLA and others
    else if (document.getElementById(myField).selectionStart || document.getElementById(myField).selectionStart == '0') {
        var startPos = document.getElementById(myField).selectionStart;
        var endPos = document.getElementById(myField).selectionEnd;
        document.getElementById(myField).value = document.getElementById(myField).value.substring(0, startPos)
            + myValue
            + document.getElementById(myField).value.substring(endPos, document.getElementById(myField).value.length);
    } else {
        document.getElementById(myField).value += myValue;
    }
}

$result = preg_replace("/[^a-zA-Z0-9]+/", "", $s);

If your definition of alphanumeric includes letters in foreign languages and obsolete scripts then you will need to use the Unicode character classes.

Try this to leave only A-Z:

$result = preg_replace("/[^A-Z]+/", "", $s);

The reason for the warning is that words like résumé contains the letter é that won't be matched by this. If you want to match a specific list of letters adjust the regular expression to include those letters. If you want to match all letters, use the appropriate character classes as mentioned in the comments.

What's so confusing about it... getters are functions that are called when you get a property, setters, when you set it. example, if you do

obj.prop = "abc";

You're setting the property prop, if you're using getters/setters, then the setter function will be called, with "abc" as an argument. The setter function definition inside the object would ideally look something like this:

set prop(var) {
   // do stuff with var...
}

I'm not sure how well that is implemented across browsers. It seems Firefox also has an alternative syntax, with double-underscored special ("magic") methods. As usual Internet Explorer does not support any of this.

Just putting this here in case it helps someone, my case was different and a bit of an odd mix. I was getting this on a request that was accessed via superagent - the problem had nothing to do with certificates (which were setup properly) and all to do with the fact that I was then passing the superagent result through the async module's waterfall callback. To fix: Instead of passing the entire result, just pass result.body through the waterfall's callback.

There seems to be a confusion about the declaration.

When strategycomes before {RANDOM, IMMEDIATE, SEARCH} as in the following,

enum strategy {RANDOM, IMMEDIATE, SEARCH};

you are creating a new type named enum strategy. However, when declaring the variable, you need to use enum strategy itself. You cannot just use strategy. So the following is invalid.

enum strategy {RANDOM, IMMEDIATE, SEARCH};
strategy a;

While, the following is valid

enum strategy {RANDOM, IMMEDIATE, SEARCH};

enum strategy queen = RANDOM;
enum strategy king = SEARCH;
enum strategy pawn[100];

When strategy comes after {RANDOM, IMMEDIATE, SEARCH}, you are creating an anonymous enum and then declaring strategy to be a variable of that type.

So now, you can do something like

enum {RANDOM, IMMEDIATE, SEARCH} strategy;
strategy = RANDOM;

However, you cannot declare any other variable of type enum {RANDOM, IMMEDIATE, SEARCH} because you have never named it. So the following is invalid

enum {RANDOM, IMMEDIATE, SEARCH} strategy;
enum strategy a = RANDOM;

You can combine both the definitions too

enum strategy {RANDOM, IMMEDIATE, SEARCH} a, b;

a = RANDOM;
b = SEARCH;
enum strategy c = IMMEDIATE;

Typedef as noted before is used for creating a shorter variable declaration.

typedef enum {RANDOM, IMMEDIATE, SEARCH} strategy;

Now you have told compiler that enum {RANDOM, IMMEDIATE, SEARCH} is synonomous to strategy. So now you can freely use strategy as variable type. You don't need to type enum strategy anymore. The following is valid now

strategy x = RANDOM;

You can also combine Typedef along with enum name to get

typedef enum strategyName {RANDOM, IMMEDIATE, SEARCH} strategy;

There's not much advantage of using this method apart from the fact that you can now use strategy and enum strategyName interchangeably.

typedef enum strategyName {RANDOM, IMMEDIATE, SEARCH} strategy;

enum strategyName a = RANDOM;
strategy b = SEARCH;

As a heads up to others, I've oberserved that at least as manifested by TypeScript compiled by WebPack for Angular 2, you quietly get overWRITTEN instead of overLOADED methods.

myComponent {
  method(): { console.info("no args"); },
  method(arg): { console.info("with arg"); }
}

Calling:

myComponent.method()

seems to execute the method with arguments, silently ignoring the no-arg version, with output:

with arg

This has been working for me:(Android studio)

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.update_credential, container, false);
        Button bt_login = (Button) rootView.findViewById(R.id.btnSend);

        bt_login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                System.out.println("Hi its me");


            }// end onClick
        });

        return rootView;

    }// end onCreateView

You also can do type switches:

switch v := myInterface.(type) {
case int:
    // v is an int here, so e.g. v + 1 is possible.
    fmt.Printf("Integer: %v", v)
case float64:
    // v is a float64 here, so e.g. v + 1.0 is possible.
    fmt.Printf("Float64: %v", v)
case string:
    // v is a string here, so e.g. v + " Yeah!" is possible.
    fmt.Printf("String: %v", v)
default:
    // And here I'm feeling dumb. ;)
    fmt.Printf("I don't know, ask stackoverflow.")
}

This worked for me:

dialog.setView(dialog.getLayoutInflater().inflate(R.layout.custom_dialog_layout, null));

If you add the android:theme="@style/Theme.AppCompat.Light" to <application> in AndroidManifest.xml file, problem is solving.

Instead of using <div>, it would be better to use to provide the <tr> (which you want to hide) an id and then hiding it using javascript.

You need to handle the AppDomain.AssemblyResolve or AppDomain.ReflectionOnlyAssemblyResolve events (depending on which load you're doing) in case the referenced assembly is not in the GAC or on the CLR's probing path.

When you set targetSdkVersion="xx", you are certifying that your app works properly (e.g., has been thoroughly and successfully tested) at API level xx.

A version of Android running at an API level above xx will apply compatibility code automatically to support any features you might be relying upon that were available at or prior to API level xx, but which are now obsolete at that Android version's higher level.

Conversely, if you are using any features that became obsolete at or prior to level xx, compatibility code will not be automatically applied by OS versions at higher API levels (that no longer include those features) to support those uses. In that situation, your own code must have special case clauses that test the API level and, if the OS level detected is a higher one that no longer has the given API feature, your code must use alternate features that are available at the running OS's API level.

If it fails to do this, then some interface features may simply not appear that would normally trigger events within your code, and you may be missing a critical interface feature that the user needs to trigger those events and to access their functionality (as in the example below).

As stated in other answers, you might set targetSdkVersion higher than minSdkVersion if you wanted to use some API features initially defined at higher API levels than your minSdkVersion, and had taken steps to ensure that your code could detect and handle the absence of those features at lower levels than targetSdkVersion.

In order to warn developers to specifically test for the minimum API level required to use a feature, the compiler will issue an error (not just a warning) if code contains a call to any method that was defined at a later API level than minSdkVersion, even if targetSdkVersion is greater than or equal to the API level at which that method was first made available. To remove this error, the compiler directive

@TargetApi(nn)

tells the compiler that the code within the scope of that directive (which will precede either a method or a class) has been written to test for an API level of at least nn prior to calling any method that depends upon having at least that API level. For example, the following code defines a method that can be called from code within an app that has a minSdkVersion of less than 11 and a targetSdkVersion of 11 or higher:

@TargetApi(11)
    public void refreshActionBarIfApi11OrHigher() {
      //If the API is 11 or higher, set up the actionBar and display it
      if(Build.VERSION.SDK_INT >= 11) {
        //ActionBar only exists at API level 11 or higher
        ActionBar actionBar = getActionBar();

        //This should cause onPrepareOptionsMenu() to be called.
        // In versions of the API prior to 11, this only occurred when the user pressed 
        // the dedicated menu button, but at level 11 and above, the action bar is 
        // typically displayed continuously and so you will need to call this
        // each time the options on your menu change.
        invalidateOptionsMenu();

        //Show the bar
        actionBar.show();
    }
}

You might also want to declare a higher targetSdkVersion if you had tested at that higher level and everything worked, even if you were not using any features from an API level higher than your minSdkVersion. This would be just to avoid the overhead of accessing compatibility code intended to adapt from the target level down to the min level, since you would have confirmed (through testing) that no such adaptation was required.

An example of a UI feature that depends upon the declared targetSdkVersion would be the three-vertical-dot menu button that appears on the status bar of apps having a targetSdkVersion less than 11, when those apps are running under API 11 and higher. If your app has a targetSdkVersion of 10 or below, it is assumed that your app's interface depends upon the existence of a dedicated menu button, and so the three-dot button appears to take the place of the earlier dedicated hardware and/or onscreen versions of that button (e.g., as seen in Gingerbread) when the OS has a higher API level for which a dedicated menu button on the device is no longer assumed. However, if you set your app's targetSdkVersion to 11 or higher, it is assumed that you have taken advantage of features introduced at that level that replace the dedicated menu button (e.g., the Action Bar), or that you have otherwise circumvented the need to have a system menu button; consequently, the three-vertical-dot menu "compatibility button" disappears. In that case, if the user can't find a menu button, she can't press it, and that, in turn, means that your activity's onCreateOptionsMenu(menu) override might never get invoked, which, again in turn, means that a significant part of your app's functionality could be deprived of its user interface. Unless, of course, you have implemented the Action Bar or some other alternative means for the user to access these features.

minSdkVersion, by contrast, states a requirement that a device's OS version have at least that API level in order to run your app. This affects which devices are able to see and download your app when it is on the Google Play app store (and possibly other app stores, as well). It's a way of stating that your app relies upon OS (API or other) features that were established at that level, and does not have an acceptable way to deal with the absence of those features.

An example of using minSdkVersion to ensure the presence of a feature that is not API-related would be to set minSdkVersion to 8 in order to ensure that your app will run only on a JIT-enabled version of the Dalvik interpreter (since JIT was introduced to the Android interpreter at API level 8). Since performance for a JIT-enabled interpreter can be as much as five times that of one lacking that feature, if your app makes heavy use of the processor then you might want to require API level 8 or above in order to ensure adequate performance.

In Eclipse it is very easy to point Tomcat to a new JVM (in this example JRE6). My problem was I couldn't find where to do it. Here is the trick:

1. On the ECLIPSE top menu FILE pull down tab, select NEW, -->Other
2. ...on the New Server: Select A Wizard window, select: Server-> Server... click NEXT
3. . on the New Server: Define a New Server window, select Apache> Tomcat 7 Server
4. ..now click the line in blue and underlined entitled: Configure Runtime Environments
5. on the Server Runtime Environments window,
6. ..select Apache, expand it(click on the arrow to the left), select TOMCAT v7.0, and click EDIT.
7. you will see a window called EDIT SERVER RUNTIME ENVIRONMENT: TOMCAT SERVER
8. On this screen there is a pulldown labeled JREs.
9. You should find your JRE listed like JRE1.6.0.33. If not use the Installed JRE button.
10. Select the desired JRE. Click the FINISH button.
11. Gracefully exit, in the Server: Server Runtime Environments window, click OK
12. in the New Server: Define a new Server window, hit NEXT
13. in the New Server: Add and Remove Window, select apps and install them on the server.
14. in the New Server: Add and Remove Window, click Finish

That's all. Interesting, only steps 7-10 seem to matter, and they will change the JRE used on all servers you have previously defined to use TOMCAT v7.0. The rest of the steps are just because I can't find any other way to get to the screen except by defining a new server. Does anyone else know an easier way?

To add rows to existing DataTable in Dataset:

DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);

This works reliably for me in my main sub.

Dim defDate1 As Date, defDate2 As Date

'** Set default date range to previous month
defDate1 = CDate(Month(Now) & "/1/" & Year(Now))
defDate1 = DateAdd("m", -1, defDate1)
defDate2 = DateAdd("d", -1, DateAdd("m", 1, defDate1))

For Spooling in Oracle SQL Developer, here is the solution.

set heading on

set linesize 1500

set colsep '|'

set numformat 99999999999999999999

set pagesize 25000

spool E:\abc.txt

@E:\abc.sql;

spool off

The hint is :

1. when we spool from sql plus , then the whole query is required.

2. when we spool from Oracle Sql Developer , then the reference path of the query required as given in the specified example.

First you need to separate your class from the further extensions ex you cannot extend AddAddressComponent.defaultProps within the class instead move it outside.

I will also recommend you to read about the Constructor and React's lifecycle: see Component Specs and Lifecycle

Here is what you want:

import PropTypes from 'prop-types';

class AddAddressComponent extends React.Component {
  render() {
    let { provinceList, cityList } = this.props;
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props');
    }
  }
}

AddAddressComponent.contextTypes = {
  router: PropTypes.object.isRequired
};

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
};

AddAddressComponent.propTypes = {
  userInfo: PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

export default AddAddressComponent;

A much shorter alternative is below:

Path filePath = Paths.get("file.txt");
Scanner scanner = new Scanner(filePath);
List<Integer> integers = new ArrayList<>();
while (scanner.hasNext()) {
    if (scanner.hasNextInt()) {
        integers.add(scanner.nextInt());
    } else {
        scanner.next();
    }
}

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. Although default delimiter is whitespace, it successfully found all integers separated by new line character.

The idea behind Dijkstra's Algorithm is to explore all the nodes of the graph in an ordered way. The algorithm stores a priority queue where the nodes are ordered according to the cost from the start, and in each iteration of the algorithm the following operations are performed:

1. Extract from the queue the node with the lowest cost from the start, N
2. Obtain its neighbors (N') and their associated cost, which is cost(N) + cost(N, N')
3. Insert in queue the neighbor nodes N', with the priority given by their cost

It's true that the algorithm calculates the cost of the path between the start (A in your case) and all the rest of the nodes, but you can stop the exploration of the algorithm when it reaches the goal (Z in your example). At this point you know the cost between A and Z, and the path connecting them.

I recommend you to use a library which implements this algorithm instead of coding your own. In Java, you might take a look to the Hipster library, which has a very friendly way to generate the graph and start using the search algorithms.

Here you have an example of how to define the graph and start using Dijstra with Hipster.

// Create a simple weighted directed graph with Hipster where
// vertices are Strings and edge values are just doubles
HipsterDirectedGraph<String,Double> graph = GraphBuilder.create()
  .connect("A").to("B").withEdge(4d)
  .connect("A").to("C").withEdge(2d)
  .connect("B").to("C").withEdge(5d)
  .connect("B").to("D").withEdge(10d)
  .connect("C").to("E").withEdge(3d)
  .connect("D").to("F").withEdge(11d)
  .connect("E").to("D").withEdge(4d)
  .buildDirectedGraph();

// Create the search problem. For graph problems, just use
// the GraphSearchProblem util class to generate the problem with ease.
SearchProblem p = GraphSearchProblem
  .startingFrom("A")
  .in(graph)
  .takeCostsFromEdges()
  .build();

// Search the shortest path from "A" to "F"
System.out.println(Hipster.createDijkstra(p).search("F"));

You only have to substitute the definition of the graph for your own, and then instantiate the algorithm as in the example.

I hope this helps!

In python 2.6 the '%' operator performed a modulus. I don't think they changed it in 3.0.1

The modulo operator tells you the remainder of a division of two numbers.

The best way is:

By default, Maven will always look in the official Maven repository, which is http://repo1.maven.org.

When Maven tries to build a project, it will look in your local repository (by default ~/.m2/repository but you can configure it by changing the <localRepository> value in your ~/.m2/settings.xml) to find any dependency, plugin or report defined in your pom.xml. If the adequate artifact is not found in your local repository, it will look in all external repositories configured, starting with the default one, http://repo1.maven.org.

You can configure Maven to avoid this default repository by setting a mirror in your settings.xml file:

<mirrors>
    <mirror>
        <id>repoMirror</id>
        <name>Our mirror for Maven repository</name>
        <url>http://the/server/</url>
        <mirrorOf>*</mirrorOf>
    </mirror>
</mirrors>

This way, instead of contacting http://repo1.maven.org, Maven will contact your entreprise repository (http://the/server in this example).

If you want to add another repository, you can define a new one in your settings.xml file:

<profiles>
    <profile>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <repositories>
            <repository>
                <id>foo.bar</id>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
                <url>http://new/repository/server</url>
            </repository>
        </repositories>

You can see the complete settings.xml model here.

Concerning the clean process, you can ask Maven to run it offline. In this case, Maven will not try to reach any external repositories:

mvn -o clean 

Try

byte[] incomingByteArray = receive...; // This is your Base64-encoded bute[]

byte[] decodedByteArray =Convert.FromBase64String (Encoding.ASCII.GetString (incomingByteArray)); 
// This work because all Base64-encoding is done with pure ASCII characters

If you want another approach for solving it that is does not depend on value_counts or scipy.stats you can use the Counter collection

from collections import Counter
get_most_common = lambda values: max(Counter(values).items(), key = lambda x: x[1])[0]

Which can be applied to the above example like this

src = pd.DataFrame({'Country' : ['USA', 'USA', 'Russia','USA'], 
              'City' : ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
              'Short_name' : ['NY','New','Spb','NY']})

src.groupby(['Country','City']).agg(get_most_common)

Here's something I came up with after applying a few principles other SO posts, including Aaron's link:

AnnotationPin *myAnnotation = (AnnotationPin *)annotation;

self = [super initWithAnnotation:myAnnotation reuseIdentifier:reuseIdentifier];
self.backgroundColor = [UIColor greenColor];
self.frame = CGRectMake(0,0,30,30);
imageView = [[UIImageView alloc] initWithImage:myAnnotation.THEIMAGE];
imageView.frame = CGRectMake(3,3,20,20);
imageView.layer.masksToBounds = NO;
[self addSubview:imageView];
[imageView release];

CGSize titleSize = [myAnnotation.THETEXT sizeWithFont:[UIFont systemFontOfSize:12]];
CGRect newFrame = self.frame;
newFrame.size.height = titleSize.height + 12;
newFrame.size.width = titleSize.width + 32;
self.frame = newFrame;
self.layer.borderColor = [UIColor colorWithRed:0 green:.3 blue:0 alpha:1.0f].CGColor;
self.layer.borderWidth = 3.0;
        
UILabel *infoLabel = [[UILabel alloc] initWithFrame:CGRectMake(26,5,newFrame.size.width-32,newFrame.size.height-12)];
infoLabel.text = myAnnotation.title;
infoLabel.backgroundColor = [UIColor clearColor];
infoLabel.textColor = [UIColor blackColor];
infoLabel.textAlignment = UITextAlignmentCenter;
infoLabel.font = [UIFont systemFontOfSize:12];

[self addSubview:infoLabel];
[infoLabel release];

In this example, I'm adding a custom pin to a MKAnnotation class that resizes a UILabel according to the text size. It also adds an image on the left side of the view, so you see some of the code managing the proper spacing to handle the image and padding.

The key is to use CGSize titleSize = [myAnnotation.THETEXT sizeWithFont:[UIFont systemFontOfSize:12]]; and then redefine the view's dimensions. You can apply this logic to any view.

Although Aaron's answer works for some, it didn't work for me. This is a far more detailed explanation that you should try immediately before going anywhere else if you want a more dynamic view with an image and resizable UILabel. I already did all the work for you!!

ALTER TABLE xxx AUTO_INCREMENT =1; or clear your table by TRUNCATE

You can use // instead of single /. That converts to int directly.

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

Please note that Arrays.stream(arr) create a LongStream (or IntStream, ...) instead of Stream so the map function cannot be used to modify the type. This is why .mapToLong, mapToObject, ... functions are provided.

Please try the below code:

<script> 
 const games = {

  "Minecraft": "476",
  "Call of Duty": "182"
 };

Object.keys(games).forEach((item, index, array) => {
  var msg = item+' '+games[item];
  console.log(msg);
});

if you're using JQuery:

var obj = jQuery.parseJSON('{"path":"/img/filename.jpg"}');
console.log(obj.path); // will print /img/filename.jpg

REMEMBER: eval is evil! :D

I found out after trying all the solutions on this page.

If visible menu

menu.findItem(R.id.id_name).setVisible(true);

If hide menu

menu.findItem(R.id.id_name).setVisible(false);

A pattern that I particularly like is to combine nested classes with the factory pattern:

public abstract class BankAccount
{
  private BankAccount() {} // prevent third-party subclassing.
  private sealed class SavingsAccount : BankAccount { ... }
  private sealed class ChequingAccount : BankAccount { ... }
  public static BankAccount MakeSavingAccount() { ... }
  public static BankAccount MakeChequingAccount() { ... }
}

By nesting the classes like this, I make it impossible for third parties to create their own subclasses. I have complete control over all the code that runs in any bankaccount object. And all my subclasses can share implementation details via the base class.

You can use Replace instead of INSERT ... ON DUPLICATE KEY UPDATE.

This could be because of the reason that the credentials are saved and you need to update those credentials and you can do that by following the below steps

control panel-> credential manager ->under generic credential you will be able to see the credentials related to git

Try to update them if that does not work delete them and add new ones

for other platforms or different versions of the operating system you need to find out where the credentails are saved related to git and update them.

Just use Python's standard string formatting methods:

>>> "{0:.2}".format(1.234232)
'1.2'
>>> "{0:.3}".format(1.234232)
'1.23'

If you are using a Python version under 2.6, use

>>> "%f" % 1.32423
'1.324230'
>>> "%.2f" % 1.32423
'1.32'
>>> "%d" % 1.32423
'1'

Not sure exactly what you try to denote with that syntax, but in almost all RDBMS-es you can use a subquery in the FROM clause (sometimes called an "inline-view"):

SELECT..
FROM (
     SELECT ...
     FROM ...
     ) my_select
WHERE ...

In advanced "enterprise" RDBMS-es (like oracle, SQL Server, postgresql) you can use common table expressions which allows you to refer to a query by name and reuse it even multiple times:

-- Define the CTE expression name and column list.
WITH Sales_CTE (SalesPersonID, SalesOrderID, SalesYear)
AS
-- Define the CTE query.
(
    SELECT SalesPersonID, SalesOrderID, YEAR(OrderDate) AS SalesYear
    FROM Sales.SalesOrderHeader
    WHERE SalesPersonID IS NOT NULL
)
-- Define the outer query referencing the CTE name.
SELECT SalesPersonID, COUNT(SalesOrderID) AS TotalSales, SalesYear
FROM Sales_CTE
GROUP BY SalesYear, SalesPersonID
ORDER BY SalesPersonID, SalesYear;

(example from http://msdn.microsoft.com/en-us/library/ms190766(v=sql.105).aspx)

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

CASE 1 : SQLite 3.25.0+

Only the Version 3.25.0 of SQLite supports renaming columns. If your device is meeting this requirement, things are quite simple. The below query would solve your problem:

ALTER TABLE "MyTable" RENAME COLUMN "OldColumn" TO "NewColumn";

CASE 2 : SQLite Older Versions

You have to follow a different Approach to get the result which might be a little tricky

For example, if you have a table like this:

CREATE TABLE student(Name TEXT, Department TEXT, Location TEXT)

And if you wish to change the name of the column Location

Step 1: Rename the original table:

ALTER TABLE student RENAME TO student_temp;

Step 2: Now create a new table student with correct column name:

CREATE TABLE student(Name TEXT, Department TEXT, Address TEXT)

Step 3: Copy the data from the original table to the new table:

INSERT INTO student(Name, Department, Address) SELECT Name, Department, Location FROM student_temp;

Note: The above command should be all one line.

Step 4: Drop the original table:

DROP TABLE student_temp;

With these four steps you can manually change any SQLite table. Keep in mind that you will also need to recreate any indexes, viewers or triggers on the new table as well.

This following code should extract face in images and save faces on disk

def detect(image):
    image_faces = []
    bitmap = cv.fromarray(image)
    faces = cv.HaarDetectObjects(bitmap, cascade, cv.CreateMemStorage(0))
    if faces:
        for (x,y,w,h),n in faces:
            image_faces.append(image[y:(y+h), x:(x+w)])
            #cv2.rectangle(image,(x,y),(x+w,y+h),(255,255,255),3)
    return image_faces

if __name__ == "__main__":
    cam = cv2.VideoCapture(0)
    while 1:
        _,frame =cam.read()
        image_faces = []
        image_faces = detect(frame)
        for i, face in enumerate(image_faces):
            cv2.imwrite("face-" + str(i) + ".jpg", face)

        #cv2.imshow("features", frame)
        if cv2.waitKey(1) == 0x1b: # ESC
            print 'ESC pressed. Exiting ...'
            break

For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.

I was facing this error because I tried to compare two dates using the following Method

var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator

However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.

Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime() method was simply not added to the prototype.

Solution

In this case, recreating a date-Object based on your dates will fix the issue.

var res = new Date(dat1).getTime() > new Date(dat2).getTime()

Edit:

I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.

The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.

class Details {
    description: string;
    date: Date;
    score: number;
    approved: boolean;

    constructor(data: any) {
      Object.assign(this, data);
    }
}

and to perform the mapping:

public getDetails(id: number): Promise<Details> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details/${id}`)
               .map(response => new Details(response.json()))
               .toPromise();
}

for arrays use:

public getDetails(): Promise<Details[]> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details`)
               .map(response => {
                   const array = JSON.parse(response.json()) as any[];
                   const details = array.map(data => new Details(data));
                   return details;
               })
               .toPromise();
}

display:none to hide and set display:block to show.

Option 1 is to use display:table-cell. You need to unfloat the Bootstrap col-* using float:none..

.center {
    display:table-cell;
    vertical-align:middle;
    float:none;
}

http://bootply.com/94394

Option 2 is display:flex to vertical align the row with flexbox:

.row.center {
   display: flex;
   align-items: center;
}

Vertical centering is very different in Bootstrap 4. See this answer for Bootstrap 4 https://stackoverflow.com/a/41464397/171456

There are two ways to handle the situation where we do not want the index to be stored in csv file.

1. As others have stated you can use index=False while saving your
   dataframe to csv file.

   df.to_csv('file_name.csv',index=False)

2. Or you can save your dataframe as it is with an index, and while reading you just drop the column unnamed 0 containing your previous index.Simple!

   df.to_csv(' file_name.csv ')
df_new = pd.read_csv('file_name.csv').drop(['unnamed 0'],axis=1)

Unless you're doing vector graphics, there's no way to resize an image without potentially losing some image quality.

Data validation drop down

There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.

The steps in Excel 2010 are:

• Create your list with matching values.
• On the Data tab choose Data Validation
• The Data validation form will be displayed
• Set the Allow dropdown to List
• Set the Source range to the first part of your list
• Click on OK (User messages can be added if required)

In a cell enter a formula like this

=VLOOKUP(A2,$D$3:$E$5,2,FALSE)

which will return the matching value from the second part of your list.

Form control drop down

Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.

The steps in Excel 2010 are:

• Create your list of data in a worksheet
• Click on the Developer tab and dropdown on the Insert option
• In the Form section choose Combo box or List box
• Use the mouse to draw the box on the worksheet
• Right click on the box and select Format control
• The Format control form will be displayed
• Click on the Control tab
• Set the Input range to your list of data
• Set the Cell link range to the cell where you want the number of the selected item to appear
• Click on OK

here is mine

echo Math+ 
ECHO First num:
 SET /P a= 
ECHO Second num:
 SET /P b=
 set /a s=%a%+%b% 
echo Result: %s%

Try

String[] splited = str.split("\\s");

As already said, on runtime there is no difference (in the class file it is always fully qualified, and after loading and linking the class there are direct pointers to the referred method), and everything in the java.lang package is automatically imported, as is everything in the current package.

The compiler might have to search some microseconds longer, but this should not be a reason - decide for legibility for human readers.

By the way, if you are using lots of static methods (from Math, for example), you could also write

import static java.lang.Math.*;

and then use

sqrt(x)

directly. But only do this if your class is math heavy and it really helps legibility of bigger formulas, since the reader (as the compiler) first would search in the same class and maybe in superclasses, too. (This applies analogously for other static methods and static variables (or constants), too.)

Since I only use admin interface in my app, I put this in the admin.py :

admin.site.site_header = 'My administration'

In addition to other answers here, if the value is an integral constant, a public enum in a class or struct will work. A variable - constant or otherwise - at the root of a namespace is another option, or a static public member of a class or struct is a third option.

MyClass::eSomeConst (enum)
MyNamespace::nSomeValue 
MyStruct::nSomeValue (static) 

Based on William McBrine's answer, here is a solution for fixed-length strings which is 9% faster for my use case:

import itertools
import struct
def make_strxor(size):
    def strxor(a, b, izip=itertools.izip, pack=struct.pack, unpack=struct.unpack, fmt='%dB' % size):
        return pack(fmt, *(a ^ b for a, b in izip(unpack(fmt, a), unpack(fmt, b))))
    return strxor
strxor_3 = make_strxor(3)
print repr(strxor_3('foo', 'bar'))

Try this

$('.slidingDiv').toggle("slide", {direction: "right" }, 1000);

Just read it in to MATLAB in one block

fid = fopen('file.csv');
data=textscan(fid,'%s %f %f','delimiter',',');
fclose(fid);

You can then process it using logical addressing

ind50 = data{2}>=50 ;

ind50 is then an index of the rows where column 2 is greater than 50. So

data{1}(ind50)

will list all the strings for the rows of interest. Then just use fprintf to write out your data to the new file

Due to my subversion state, I had to get creative. svn st showed M,A and ~ statuses. I only wanted M and A so...

svn st | grep ^[A\|M] | cut -d' ' -f8- > targets.txt

This command says find all the lines output by svn st that start with M or A, cut using space delimiter, then get colums 8 to the end. Dump that into targets.txt and overwrite.

Then modify targets.txt to prune the file list further. Then run below to commit:

svn ci -m "My commit message" --targets targets.txt

Probably not the most common use case, but hopefully it helps someone.

With git there is a https format

https://github.com/equivalent/we_demand_serverless_ruby.git

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

Well, there's always the low tech solution of adding logging of the size of your maps when you modify them, then search the logs for which maps are growing beyond a reasonable size.

Storing money as BIGINT multiplied by 100 or more with the reason to use less storage space makes no sense in all "normal" situations.

• To stay aligned with GAAP it is sufficient to store currencies in DECIMAL(13,4)
• MySQL manual reads that it needs 4 bytes per 9 digits to store DECIMAL.
  • https://dev.mysql.com/doc/refman/8.0/en/precision-math-decimal-characteristics.html
• DECIMAL(13,4) represents 9 digits + 4 fraction digits (decimal places) => 4 + 2 bytes = 6 bytes
• compare to 8 bytes required to store BIGINT.

Here's how I do it. You could do it the same way, or use this code for ideas.

let s = "www.stackoverflow.com"
s.substringWithRange(0..<s.lastIndexOf("."))

Here are the extensions I use:

import Foundation
extension String {

  var length: Int {
    get {
      return countElements(self)
    }
  }

  func indexOf(target: String) -> Int {
    var range = self.rangeOfString(target)
    if let range = range {
      return distance(self.startIndex, range.startIndex)
    } else {
      return -1
    }
  }

  func indexOf(target: String, startIndex: Int) -> Int {
    var startRange = advance(self.startIndex, startIndex)        
    var range = self.rangeOfString(target, options: NSStringCompareOptions.LiteralSearch, range: Range<String.Index>(start: startRange, end: self.endIndex))
    if let range = range {
      return distance(self.startIndex, range.startIndex)
    } else {
      return -1
    }
  }

  func lastIndexOf(target: String) -> Int {
    var index = -1
    var stepIndex = self.indexOf(target)
    while stepIndex > -1 {
      index = stepIndex
      if stepIndex + target.length < self.length {
        stepIndex = indexOf(target, startIndex: stepIndex + target.length)
      } else {
        stepIndex = -1
      }
    }
    return index
  } 

  func substringWithRange(range:Range<Int>) -> String {
    let start = advance(self.startIndex, range.startIndex)
    let end = advance(self.startIndex, range.endIndex)
    return self.substringWithRange(start..<end)
  }

}

Generally I am a strong proponent of extensions, especially for needs like string manipulation, searching, and slicing.

Also, if you have Boost, use transform_iterator to avoid making a temporary copy of the keys.

You can use Numpad-9 and Numpad-7 to rotate on Windows and Ubuntu.

You are trying to set "++" on a jQuery element!

YOu could declare a js variable

var counter = 0;

and in jQuery code do:

$("#counter").html(counter++);

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

mktemp is probably the most versatile, especially if you plan to work with the file for a while.

You can also use a process substitution operator <() if you only need the file temporarily as input to another command, e.g.:

$ diff <(echo hello world) <(echo foo bar)

I have a similar issue. It appears that PHP does not like php code inside included file. In your case solution is quite simple. Remove php code from navbar.php, simply leave plain HTML in it and it will work.

Another recursive solution

 public static String reverse(ArrayList<Float> list) {
   if (list.size() == 1) {
       return " " +list.get(0);
   }
   else {
       return " "+ list.remove(list.size() - 1) + reverse(list);
   } 
 }

In new APIs don't forget about TAG:

notify(String tag, int id, Notification notification)

and correspondingly

cancel(String tag, int id) 

instead of:

cancel(int id)

https://developer.android.com/reference/android/app/NotificationManager

you can use use JQuery for deep copying :

var arr =[['abc'],['xyz']];
var newArr = $.extend(true, [], arr);
newArr.shift().shift();

console.log(arr); //arr still has [['abc'],['xyz']]
