Things that can cause a delete to be slow:

• deleting a lot of records
• many indexes
• missing indexes on foreign keys in child tables. (thank you to @CesarAlvaradoDiaz for mentioning this in the comments)
• deadlocks and blocking
• triggers
• cascade delete (those ten parent records you are deleting could mean millions of child records getting deleted)
• Transaction log needing to grow
• Many Foreign keys to check

So your choices are to find out what is blocking and fix it or run the deletes in off hours when they won't be interfering with the normal production load. You can run the delete in batches (useful if you have triggers, cascade delete, or a large number of records). You can drop and recreate the indexes (best if you can do that in off hours too).

If you are doing this in browser there are no character encoding libraries built-in, but you can get by with:

function pad(n) {
    return n.length < 2 ? "0" + n : n;
}

var array = new Uint8Array(data);
var str = "";
for( var i = 0, len = array.length; i < len; ++i ) {
    str += ( "%" + pad(array[i].toString(16)))
}

str = decodeURIComponent(str);

Here's a demo that decodes a 3-byte UTF-8 unit: http://jsfiddle.net/Z9pQE/

I posted this question and never saw the feedback (which came in several months after, it seems :).

As Kinlan mentioned, ALLOW-FROM is not supported in all browsers as an X-Frame-Options value.

The solution was to branch based on browser type. For IE, ship X-Frame-Options. For everyone else, ship X-Content-Security-Policy.

Hope this helps, and sorry for taking so long to close the loop!

I think you want

output <- do.call(rbind,lapply(z,matrix,ncol=10,byrow=TRUE))

i.e. combining @BlueMagister's use of do.call(rbind,...) with an lapply statement to convert the individual list elements into 11*10 matrices ...

Benchmarks (showing @flodel's unlist solution is 5x faster than mine, and 230x faster than the original approach ...)

n <- 1000
z <- replicate(n,matrix(1:110,ncol=10,byrow=TRUE),simplify=FALSE)
library(rbenchmark)
origfn <- function(z) {
    output <- NULL 
    for(i in 1:length(z))
        output<- rbind(output,matrix(z[[i]],ncol=10,byrow=TRUE))
}
rbindfn <- function(z) do.call(rbind,lapply(z,matrix,ncol=10,byrow=TRUE))
unlistfn <- function(z) matrix(unlist(z), ncol = 10, byrow = TRUE)

##          test replications elapsed relative user.self sys.self 
## 1   origfn(z)          100  36.467  230.804    34.834    1.540  
## 2  rbindfn(z)          100   0.713    4.513     0.708    0.012 
## 3 unlistfn(z)          100   0.158    1.000     0.144    0.008 

If this scales appropriately (i.e. you don't run into memory problems), the full problem would take about 130*0.2 seconds = 26 seconds on a comparable machine (I did this on a 2-year-old MacBook Pro).

Did you setup your project to be compiled with 1.4 compliance? If so, do what krock said. Or to be more exact you need to select the J2SE-1.4 execution environment and check one of the installed JRE that you want to use in 1.4 compliance mode; most likely you'll have a 1.6 JRE installed, just check that one. Or install a 1.4 JRE if you have a setup kit, and use that one.

Otherwise go to your Eclipse preferences, Java -> Compiler and check if the compliance is set to 1.4. If it is change it back to 1.6. If it's not go to the project properties, and check if it has project specific settings. Go to Java Compiler, and uncheck that if you want to use the general eclipse preferences. Or set the project specific settings to 1.6, so that it's always 1.6 regardless of eclipse preferences.

How to uninstall after "make install"

Method #1 (make uninstall)

Step 1: You only need to follow this step if you've deleted/altered the build directory in any way: Download and make/make install using the exact same procedure as you did before.

Step 2: try make uninstall.

cd $SOURCE_DIR 
sudo make uninstall

If this succeeds you are done. If you're paranoid you may also try the steps of "Method #3" to make sure make uninstall didn't miss any files.

Method #2 (checkinstall -- only for debian based systems)

Overview of the process

In debian based systems (e.g. Ubuntu) you can create a .deb package very easily by using a tool named checkinstall. You then install the .deb package (this will make your debian system realize that the all parts of your package have been indeed installed) and finally uninstall it to let your package manager properly cleanup your system.

Step by step

sudo apt-get -y install checkinstall
cd $SOURCE_DIR 
sudo checkinstall

At this point checkinstall will prompt for a package name. Enter something a bit descriptive and note it because you'll use it in a minute. It will also prompt for a few more data that you can ignore. If it complains about the version not been acceptable just enter something reasonable like 1.0. When it completes you can install and finally uninstall:

sudo dpkg -i $PACKAGE_NAME_YOU_ENTERED 
sudo dpkg -r $PACKAGE_NAME_YOU_ENTERED

Method #3 (install_manifest.txt)

If a file install_manifest.txt exists in your source dir it should contain the filenames of every single file that the installation created.

So first check the list of files and their mod-time:

cd $SOURCE_DIR 
sudo xargs -I{} stat -c "%z %n" "{}" < install_manifest.txt

You should get zero errors and the mod-times of the listed files should be on or after the installation time. If all is OK you can delete them in one go:

cd $SOURCE_DIR 
mkdir deleted-by-uninstall
sudo xargs -I{} mv -t deleted-by-uninstall "{}" < install_manifest.txt

User Merlyn Morgan-Graham however has a serious notice regarding this method that you should keep in mind (copied here verbatim): "Watch out for files that might also have been installed by other packages. Simply deleting these files [...] could break the other packages.". That's the reason that we've created the deleted-by-uninstall dir and moved files there instead of deleting them.

99% of this post existed in other answers. I just collected everything useful in a (hopefully) easy to follow how-to and tried to give extra attention to important details (like quoting xarg arguments and keeping backups of deleted files).

private class ObjectAdapter extends BaseAdapter {

    private Context context;
    private List<Object>objects;

    public ObjectAdapter(Context context, List<Object> objects) {
        this.context = context;
        this.objects = objects;
    }

    @Override
    public int getCount() {
        return objects.size();
    }

    @Override
    public Object getItem(int position) {
        return objects.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        if(convertView==null){
            holder = new ViewHolder();
            convertView = LayoutInflater.from(context).inflate(android.R.layout.simple_list_item_1, parent, false);
            holder.text = (TextView) convertView.findViewById(android.R.id.text1);
            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }

        holder.text.setText(getItem(position).toString()));
        return convertView;
    }

    class ViewHolder {
        TextView text;
    }
}

Here is an implementation without using jQuery at all -
http://thezillion.wordpress.com/2012/09/27/javascript-draggable-2-no-jquery

Embed the JS file (http://zillionhost.xtreemhost.com/tzdragg/tzdragg.js) in your HTML code, and put the following code -

<script>
win.onload = function(){
 tzdragg.drag('elem1, elem2, ..... elemn');
 // ^ IDs of the draggable elements separated by a comma.
}
</script>

And the code is also easy to learn.
http://thezillion.wordpress.com/2012/08/29/javascript-draggable-no-jquery

jQuery isn't particularly helpful for sorting, but here's an elegant and efficient solution. Just write a plain JS function that takes the property name and the order (ascending or descending) and calls the native sort() method with a simple comparison function:

var people = [
    {
        "f_name": "john",
        "l_name": "doe",
        "sequence": "0",
        "title" : "president",
        "url" : "google.com",
        "color" : "333333",
    }
    // etc
];

function sortResults(prop, asc) {
    people.sort(function(a, b) {
        if (asc) {
            return (a[prop] > b[prop]) ? 1 : ((a[prop] < b[prop]) ? -1 : 0);
        } else {
            return (b[prop] > a[prop]) ? 1 : ((b[prop] < a[prop]) ? -1 : 0);
        }
    });
    renderResults();
}

Then:

sortResults('l_name', true);

Play with a working example here.

I had the same error when was trying to write an image in DCIM/camera folder on Galaxy S5 (android 6.0.1) and I figured out that only this folder is restricted. I simply could write into DCIM/any folder but not in camera. This should be brand based restriction/customization.

JavaScript developers tend to refer to the above data-structure as either an object or hash instead of a Dictionary.

Your syntax above is wrong as you are initializing the users object as null. I presume this is a typo, as the code should read:

// Initialize users as a new hash.
var users = {};
users["182982"] = "...";

To retrieve all the values from a hash, you need to iterate over it using a for loop:

function getValues (hash) {
    var values = [];
    for (var key in hash) {

        // Ensure that the `key` is actually a member of the hash and not
        // a member of the `prototype`.
        // see: http://javascript.crockford.com/code.html#for%20statement
        if (hash.hasOwnProperty(key)) {
            values.push(key);
        }
    }
    return values;
};

If you plan on doing a lot of work with data-structures in JavaScript then the underscore.js library is definitely worth a look. Underscore comes with a values method which will perform the above task for you:

var values = _.values(users);

I don't use Angular myself, but I'm pretty sure there will be a convenience method build in for iterating over a hash's values (ah, there we go, Artem Andreev provides the answer above :))

In Android studio 0.8.0 you should enable ADB integration through Tools -> Android, before run your app. Then the log cat will work correctly. Notice that if you make ADB integration disabled while your app is running and again make it enable, then the log cat dosen't show anything unless you rebuild your project.

You can use below code

$.when( Typer() ).done(function() {
       playBGM();
});

You need to tell manage.py the local ip address and the port to bind to. Something like python manage.py runserver 192.168.23.12:8000. Then use that same ip and port from the other machine. You can read more about it here in the documentation.

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

Full Working Example Link

Attempting to provide some (possible) context for OP's question by posting my own trouble. I'm working in Scala, but the error messages I'm getting all reference Java types, and the error message reads a lot like the compiler complaining that CharSequence is not a String. I confirmed in the source code that String implements the CharSequence interface, but the error message draws attention to the difference between String and CharSequence while hiding the real source of the trouble:

scala> cols
res8: Iterable[String] = List(Item, a, b)

scala> val header = String.join(",", cols)
<console>:13: error: overloaded method value join with alternatives:
  (x$1: CharSequence,x$2: java.lang.Iterable[_ <: CharSequence])String <and>
  (x$1: CharSequence,x$2: CharSequence*)String
 cannot be applied to (String, Iterable[String])
       val header = String.join(",", cols)

I was able to fix this problem with the realization that the problem wasn't String / CharSequence, but rather a mismatch between java.lang.Iterable and Scala's built-in Iterable.

scala> val header = String.join(",", coll: _*)
header: String = Item,a,b

My particular problem can also be solved via the answers at Scala: join an iterable of strings

In summary, OP and others who come across similar problems should parse the error messages very closely and see what other type conversions might be involved.

I did it that way in C# with NHibernate, but it should work the same way in Java:

public virtual void Attach()
{
    if (!HibernateSessionManager.Instance.GetSession().Contains(this))
    {
        ISession session = HibernateSessionManager.Instance.GetSession();
        using (ITransaction t = session.BeginTransaction())
        {
            session.Lock(this, NHibernate.LockMode.None);
            t.Commit();
        }
    }
}

First Lock was called on every object because Contains was always false. The problem is that NHibernate compares objects by database id and type. Contains uses the equals method, which compares by reference if it's not overwritten. With that equals method it works without any Exceptions:

public override bool Equals(object obj)
{
    if (this == obj) { 
        return true;
    } 
    if (GetType() != obj.GetType()) {
        return false;
    }
    if (Id != ((BaseObject)obj).Id)
    {
        return false;
    }
    return true;
}

Normally you need to have the same number of columns when you're using set based operators so Kangkan's answer is correct.

SAS SQL has specific operator to handle that scenario:

SAS(R) 9.3 SQL Procedure User's Guide

CORRESPONDING (CORR) Keyword

The CORRESPONDING keyword is used only when a set operator is specified. CORR causes PROC SQL to match the columns in table expressions by name and not by ordinal position. Columns that do not match by name are excluded from the result table, except for the OUTER UNION operator.

SELECT * FROM tabA
OUTER UNION CORR
SELECT * FROM tabB;

For:

+---+---+
| a | b |
+---+---+
| 1 | X |
| 2 | Y |
+---+---+

OUTER UNION CORR

+---+---+
| b | d |
+---+---+
| U | 1 |
+---+---+

<=>

+----+----+---+
| a  | b  | d |
+----+----+---+
|  1 | X  |   |
|  2 | Y  |   |
|    | U  | 1 |
+----+----+---+

U-SQL supports similar concept:

OUTER UNION BY NAME ON (*)

OUTER

requires the BY NAME clause and the ON list. As opposed to the other set expressions, the output schema of the OUTER UNION includes both the matching columns and the non-matching columns from both sides. This creates a situation where each row coming from one of the sides has "missing columns" that are present only on the other side. For such columns, default values are supplied for the "missing cells". The default values are null for nullable types and the .Net default value for the non-nullable types (e.g., 0 for int).

BY NAME

is required when used with OUTER. The clause indicates that the union is matching up values not based on position but by name of the columns. If the BY NAME clause is not specified, the matching is done positionally.

If the ON clause includes the “*” symbol (it may be specified as the last or the only member of the list), then extra name matches beyond those in the ON clause are allowed, and the result’s columns include all matching columns in the order they are present in the left argument.

And code:

@result =    
    SELECT * FROM @left
    OUTER UNION BY NAME ON (*) 
    SELECT * FROM @right;

EDIT:

The concept of outer union is supported by KQL:

kind:

inner - The result has the subset of columns that are common to all of the input tables.

outer - The result has all the columns that occur in any of the inputs. Cells that were not defined by an input row are set to null.

Example:

let t1 = datatable(col1:long, col2:string)  
[1, "a",  
2, "b",
3, "c"];
let t2 = datatable(col3:long)
[1,3];
t1 | union kind=outer t2;

Output:

+------+------+------+
| col1 | col2 | col3 |
+------+------+------+
|    1 | a    |      |
|    2 | b    |      |
|    3 | c    |      |
|      |      |    1 |
|      |      |    3 |
+------+------+------+

demo

The error for me was:

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:percent:26.0.2] AndroidManifest.xml:25:13-35
    is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
    Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:23:9-25:38 to override.

The solution for me was in my project Gradle file I needed to bump my com.google.gms:google-services version.

I was using version 3.1.1:

classpath 'com.google.gms:google-services:3.1.1

And the error resolved after I bumped it to version 3.2.1:

classpath 'com.google.gms:google-services:3.2.1

I had just upgraded all my libraries to the latest including v27.1.1 of all the support libraries and v15.0.0 of all the Firebase libraries when I saw the error.

A pure RESTful API should use the underlying protocol standard features:

1. For HTTP, the RESTful API should comply with existing HTTP standard headers. Adding a new HTTP header violates the REST principles. Do not re-invent the wheel, use all the standard features in HTTP/1.1 standards - including status response codes, headers, and so on. RESTFul web services should leverage and rely upon the HTTP standards.

2. RESTful services MUST be STATELESS. Any tricks, such as token based authentication that attempts to remember the state of previous REST requests on the server violates the REST principles. Again, this is a MUST; that is, if you web server saves any request/response context related information on the server in attempt to establish any sort of session on the server, then your web service is NOT Stateless. And if it is NOT stateless it is NOT RESTFul.

Bottom-line: For authentication/authorization purposes you should use HTTP standard authorization header. That is, you should add the HTTP authorization / authentication header in each subsequent request that needs to be authenticated. The REST API should follow the HTTP Authentication Scheme standards.The specifics of how this header should be formatted are defined in the RFC 2616 HTTP 1.1 standards – section 14.8 Authorization of RFC 2616, and in the RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.

I have developed a RESTful service for the Cisco Prime Performance Manager application. Search Google for the REST API document that I wrote for that application for more details about RESTFul API compliance here. In that implementation, I have chosen to use HTTP "Basic" Authorization scheme. - check out version 1.5 or above of that REST API document, and search for authorization in the document.

if the full message is:

kernel panic - not syncing: Attempted to kill inint !

then you should have disabled selinux and after that you have rebooted the system.

The easier way is to use a live OS and re-enable it

vim /etc/selinux/config

As of September 20th, 2016, registering is no longer required for apps that use https (or perhaps other forms of encryption): https://web.archive.org/web/20170312060607/https://www.bis.doc.gov/index.php/informationsecurity2016-updates

In fact, on SNAP-R you can no longer choose 'encryption registration':

Specifically, they note:

Encryption Registrations no longer required – some of the information from the registration now goes into the Supp. No. 8 to Part 742 report.

This means you may need to send an annual report to BIS, but you don't need to register and you can note when submitting your app that it is exempt.

Ion Todirel already mentioned an answer YES using std::reference_wrapper. Since C++11 we have a mechanism to retrieve object from std::vector and remove the reference by using std::remove_reference. Below is given an example compiled using g++ and clang with option
-std=c++11 and executed successfully.

#include <iostream>
#include <vector>
#include<functional>

class MyClass {
public:
    void func() {
        std::cout << "I am func \n";
    }

    MyClass(int y) : x(y) {}

    int getval()
    {
        return x;
    }

private: 
        int x;
};

int main() {
    std::vector<std::reference_wrapper<MyClass>> vec;

    MyClass obj1(2);
    MyClass obj2(3);

    MyClass& obj_ref1 = std::ref(obj1);
    MyClass& obj_ref2 = obj2;

    vec.push_back(obj_ref1);
    vec.push_back(obj_ref2);

    for (auto obj3 : vec)
    {
        std::remove_reference<MyClass&>::type(obj3).func();      
        std::cout << std::remove_reference<MyClass&>::type(obj3).getval() << "\n";
    }             
}

Details on return values and their meaning

Per 3.6.1 ([basic.start.main]):

A return statement in main has the effect of leaving the main function (destroying any objects with automatic storage duration) and calling std::exit with the return value as the argument. If control reaches the end of main without encountering a return statement, the effect is that of executing

return 0;

The behavior of std::exit is detailed in section 18.5 ([support.start.term]), and describes the status code:

Finally, control is returned to the host environment. If status is zero or EXIT_SUCCESS, an implementation-defined form of the status successful termination is returned. If status is EXIT_FAILURE, an implementation-defined form of the status unsuccessful termination is returned. Otherwise the status returned is implementation-defined.

What allowed me to fix the problem was going to: Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros, etc. -> Providers -> CDT GCC built-in compiler settings, enabling that and disabling the CDT Cross GCC Built-in Compiler Settings

Simply you could change the gradle.properties . i have given the sample below

To remove default user you need to configure authentication menager with no users for example:

@configuration
class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication();
    }
}

this will remove default password message and default user because in that case you are configuring InMemoryAuthentication and you will not specify any user in next steps

You should do:

#include<iostream>
using namespace std;
int main ()
{

    int sum = 0;
    int number;
    int numberitems;


    cout << "Enter number of items: \n";
    cin >> numberitems;

    for(int i=0;i<numberitems;i++)
    {
        cout << "Enter number <<i<<":" \n";
        cin >> number; sum+=number;
    }
    cout<<"sum is: "<< sum<<endl;
}

And with a while statement

#include <iostream>
using namespace std;
int main ()
{
    int sum = 0;
    int number;
    int numberitems;
    cin>>numberitems;

    cout << "Enter number: \n";

    while (count <=numberitems)
    {
        cin >> number;
        sum+=number;
    }
    cout << sum << endl;
}

Don't really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don't need to hold all the data in memory at once (This can be faster or slower depending on the library/use case)

http://www.quirksmode.org/js/cookies.html

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}

Firstly, converting an integer into string in JS is really simple:

// Start off with a number
var number = 42;
// Convert into a string by appending an empty (or whatever you like as a string) to it
var string = 42+'';
// No extra conversion is needed, even though you could actually do
var alsoString = number.toString();

If you have a number as a string and want it to be turned to an integer, you have to use the parseInt(string) for integers and parseFloat(string) for floats. Both of these functions then return the desired integer/float. Example:

// Start off with a float as a string
var stringFloat = '3.14';
// And an int as a string
var stringInt = '42';

// typeof stringInt  would give you 'string'

// Get the real float from the string
var realFloat = parseFloat(someFloat);
// Same for the int
var realInt = parseInt(stringInt);

// but typeof realInt  will now give you 'number'

What exactly are you trying to append etc, remains unclear to me from your question.

Luckily, the package-info class isn't required. I was able to fix mine problem with iowatiger08 solution.

Here is my fix showing the error message to help join the dots for some.

Error message

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://global.aon.bz/schema/cbs/archive/errorresource/0", local:"errorresource"). Expected elements are <{}errorresource>

Code before fix

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder={"error"})
@XmlRootElement(name="errorresource")
public class Errorresource

Code after fix

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder={"error"})
@XmlRootElement(name="errorresource", namespace="http://global.aon.bz/schema/cbs/archive/errorresource/0")
public class Errorresource

You can see the namespace added to @XmlRootElement as indicated in the error message.

To end up with:

• an actual Array object (not a NodeList dressed up as an Array)
• a list that is guaranteed to only include HTMLElements, not Nodes force-casted to HTMLElements
• a warm fuzzy feeling to do The Right Thing

Try this:

let nodeList : NodeList = document.getElementsByTagName('script');
let elementList : Array<HTMLElement> = [];

if (nodeList) {
    for (let i = 0; i < nodeList.length; i++) {
        let node : Node = nodeList[i];

        // Make sure it's really an Element
        if (node.nodeType == Node.ELEMENT_NODE) {
            elementList.push(node as HTMLElement);
        }
    }
}

Enjoy.

I found it works different among different jpa versions, for debug, you'd better add this configurations to show generated sql, it will save your time a lot !

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

for spring boot 2.1.6.RELEASE, it works good!

Sort sort = new Sort(Sort.Direction.DESC, "column_name");
int pageNumber = 3, pageSize = 5;
Pageable pageable = PageRequest.of(pageNumber - 1, pageSize, sort);

@Query(value = "select * from integrity_score_view " +
        "where (?1 is null or data_hour >= ?1 ) " +
        "and (?2 is null or data_hour <= ?2 ) " +
        "and (?3 is null or ?3 = '' or park_no = ?3 ) " +
        "group by park_name, data_hour ",
        countQuery = "select count(*) from integrity_score_view " +
                "where (?1 is null or data_hour >= ?1 ) " +
                "and (?2 is null or data_hour <= ?2 ) " +
                "and (?3 is null or ?3 = '' or park_no = ?3 ) " +
                "group by park_name, data_hour",
        nativeQuery = true
)
Page<IntegrityScoreView> queryParkView(Date from, Date to, String parkNo, Pageable pageable);

you DO NOT write order by and limit, it generates the right sql

To get the raw post body regardless of the content type, use request.get_data(). If you use request.data, it calls request.get_data(parse_form_data=True), which will populate the request.form MultiDict and leave data empty.

Any data type which is lower than "int" (except Boolean) is implicitly converts to "int".

In your case:

short a = 2;
short b = 3;
short c = a + b;

The result of (a+b) is implicitly converted to an int. And now you are assigning it to "short".So that you are getting the error.

short,byte,char --for all these we will get same error.

For those that could be facing the same problem and the solutions suggested above aren't working, for example in my case, I had installed mongodb-community, so you might wanna run the command below to restart your mongo server.

For those that installed mongodb-community using brew

brew services start mongodb-community

The parser is expecting some HTML content, so it sees & as the beginning of an entity, like è.

Use this workaround:

<script type="text/javascript">
// <![CDATA[
Javascript code here
// ]]>
</script>

so you specify that the code is not HTML text but just data to be used as is.

check the following link https://www.geeksforgeeks.org/how-to-create-an-unordered_map-of-user-defined-class-in-cpp/ for more details.

• the custom class must implement the == operator
• must create a hash function for the class (for primitive types like int and also types like string the hash function is predefined)

try
{

..
..
..

}

catch(Exception ex)
{

..
..
..

}

the Exception ex means all the exceptions.

For use key/value pair in json use an object and don't use array

Find name/value in array is hard but in object is easy

Ex:

var exObj = {_x000D_
  "mainData": {_x000D_
    "slide0001.html": "Looking Ahead",_x000D_
    "slide0008.html": "Forecast",_x000D_
    "slide0021.html": "Summary",_x000D_
    // another THOUSANDS KEY VALUE PAIRS_x000D_
    // ..._x000D_
  },_x000D_
  "otherdata" : { "one": "1", "two": "2", "three": "3" }_x000D_
};_x000D_
var mainData = exObj.mainData;_x000D_
// for use:_x000D_
Object.keys(mainData).forEach(function(n,i){_x000D_
  var v = mainData[n];_x000D_
  console.log('name' + i + ': ' + n + ', value' + i + ': ' + v);_x000D_
});_x000D_
_x000D_
// and string length is minimum_x000D_
console.log(JSON.stringify(exObj));_x000D_
console.log(JSON.stringify(exObj).length);

Best as an out parameter:

void testfunc(char* outStr){
  char str[10];
  for(int i=0; i < 10; ++i){
    outStr[i] = str[i];
  }
}

Called with

int main(){
  char myStr[10];
  testfunc(myStr);
  // myStr is now filled
}

If you need to print it and don't need a newline, you can use:

printf $(md5sum filename)

If you use yum search you can find the python dev package for your version of python.

For me I was using python 3.5. I ran the following

yum search python | grep devel

Which returned the following

I was then able to install the correct package for my version of python with the following cmd.

sudo yum install python35u-devel.x86_64

This works on centos for ubuntu or debian you would need to use apt-get

            try
            {

                status = int.TryParse(s3, out result);
                Console.WriteLine("OutPut3:" + result);
            }
            catch (Exception ee)
            {
                Console.WriteLine("OutPut3:" + ee.Message);
            }
            try
            {

                status = int.TryParse(s4, out result);
                Console.WriteLine("OutPut4:" + result);
            }
            catch (Exception ee)
            {
                Console.WriteLine("OutPut4:" + ee.Message);
            }

            try
            {

                status = int.TryParse(s5, out result);
                Console.WriteLine("OutPut5:" + result);
            }
            catch (Exception ee)
            {
                Console.WriteLine("OutPut5:" + ee.Message);
            }


            Console.Read();
        }
    }

You can always use Request.QueryString collection like Web forms, but you can also make MVC handle them and pass them as parameters. This is the suggested way as it's easier and it will validate input data type automatically.

You should also try my ServiceStack JsonSerializer - it's the fastest .NET JSON serializer at the moment based on the benchmarks of the leading JSON serializers and supports serializing any POCO Type, DataContracts, Lists/Dictionaries, Interfaces, Inheritance, Late-bound objects including anonymous types, etc.

Basic Example

var customer = new Customer { Name="Joe Bloggs", Age=31 };
var json = customer.ToJson();
var fromJson = json.FromJson<Customer>(); 

Note: Only use Microsofts JavaScriptSerializer if performance is not important to you as I've had to leave it out of my benchmarks since its up to 40x-100x slower than the other JSON serializers.

Just a tip for this, you don't need the BEGIN and END if it only contains a single statement.

ie:

IF(@Trans_type = 'subscr_signup')    
 set @tmpType = 'premium' 
ELSE iF(@Trans_type = 'subscr_cancel')  
     set    @tmpType = 'basic'

All of the answers so far, is missing one VERY important step, otherwise you will get "connection refused" when trying to connect.

Step 1: First enable Developer Options menu on your device, by navigating to the About menu on your device, then tapping the Build menu 5 times.

Step 2: Then go to the now visible Developer Options menu and enable USB debugging. Yes its a bit odd that you need this for Wifi debuging, but trust me, this is required.

Step 3:

adb connect [your devices ip address]

It should say that you're now connected

You could use FindBin, Cwd, File::Basename, or a combination of them. They're all in the base distribution of Perl IIRC.

I used Cwd in the past:

Cwd:

use Cwd qw(abs_path);
my $path = abs_path($0);
print "$path\n";

Task.WaitAll blocks the current thread until everything has completed.

Task.WhenAll returns a task which represents the action of waiting until everything has completed.

That means that from an async method, you can use:

await Task.WhenAll(tasks);

... which means your method will continue when everything's completed, but you won't tie up a thread to just hang around until that time.

I also came across the same issue. I was trying to build the project with a clean install goal. I simply changed it to clean package -o in the run configuration. Then I re-built the project and it worked for me.

Yes and no. All the common web browsers has a security measure to prevent that. The goal is to prevent people from creating replicas of websites, change the URL to make it look correct, and then be able to trick people and get their info.

However, some HTML5 compatible web browsers has implemented an History API that can be used for something similar to what you want:

if (history.pushState) {
    var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?myNewUrlQuery=1';
    window.history.pushState({path:newurl},'',newurl);
}

I tested, and it worked fine. It does not reload the page, but it only allows you to change the URL query. You would not be able to change the protocol or the host values.

For more information:

http://diveintohtml5.info/history.html

https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Manipulating_the_browser_history

No, there isn't. The border will always be as tall as the element.

You can achieve the same effect by wrapping the contents of the cell in a <span>, and applying height/border styles to that. Or by drawing a short vertical line in an 1 pixel wide PNG which is the correct height, and applying it as a background to the cell:

background:url(line.png) bottom right no-repeat;

You can use >> to print in another file.

echo "hello" >> logfile.txt

This is more general than .NET and Windows. Managed is an environment where you have automatic memory management, garbage collection, type safety, ... unmanaged is everything else. So for example .NET is a managed environment and C/C++ is unmanaged.

Separate your rules with a semi colon in a single declaration:

<span style="color:blue;font-style:italic">Test</span>

1. Include the Open Graph XML namespace extension to your HTML declaration

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:fb="http://ogp.me/ns/fb#">

2. Inside your <head></head> use the following meta tag to define the image you want to use

<meta property="og:image" content="fully_qualified_image_url_here" />

Read more about open graph protocol here.

After doing the above, use the Facebook "Object Debugger" if the image does not show up correctly. Also note the first time shared it still won't show up unless height and width are also specified, see Share on Facebook - Thumbnail not showing for the first time

In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.

Consider using sessionStorage directly: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

When you are using Vue directives, the expressions are evaluated in the context of Vue, so you don't need to wrap things in {}.

@click is just shorthand for v-on:click directive so the same rules apply.

In your case, simply use @click="addToCount(item.contactID)"

A more functional approach would be by using dict.get

input_nums = [int(in_str) for in_str in input_str.split())
strikes = list(map(number_map.get, input_nums.split()))

One can observe that the conversion is a little clumsy, better would be to use the abstraction of function composition:

def compose2(f, g):
    return lambda x: f(g(x))

strikes = list(map(compose2(number_map.get, int), input_str.split()))

Example:

list(map(compose2(number_map.get, int), ["1", "2", "7"]))
Out[29]: [-3, -2, None]

Obviously in Python 3 you would avoid the explicit conversion to a list. A more general approach for function composition in Python can be found here.

(Remark: I came here from the Design of Computer Programs Udacity class, to write:)

def word_score(word):
    "The sum of the individual letter point scores for this word."
    return sum(map(POINTS.get, word))

This can be used in automation scripts if you don't need all tables in all schemas:

  for table in $(psql -qAntc '\dt' | cut -d\| -f2); do
      ...
  done

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS

https://developer.wordpress.org/reference/functions/wp_hash_password/

Another option would be to use the if with a colon and an endif instead of the brackets:

<?php if ( has_post_thumbnail() ): ?>
    <div class="gridly-image">
        <a href="<?php the_permalink(); ?>">
        <?php the_post_thumbnail('summary-image', array('class' => 'overlay', 'title'=> the_title('Read Article ',' now',false) )); ?>
        </a>
    </div>
<?php endif; ?>

<div class="date">
    <span class="day"><?php the_time('d'); ?></span>
    <div class="holder">
        <span class="month"><?php the_time('M'); ?></span>
        <span class="year"><?php the_time('Y'); ?></span>
    </div>
</div>

Also, you might want to take a look at NetworkX

Try This

<script>
  var phpadd= <?php echo add(1,2);?> //call the php add function
  var phpmult= <?php echo mult(1,2);?> //call the php mult function
  var phpdivide= <?php echo divide(1,2);?> //call the php divide function
</script>

@jason-mccreary is totally right. Besides I recommend you this code to get more info in case of malfunction:

$rest = curl_exec($crl);

if ($rest === false)
{
    // throw new Exception('Curl error: ' . curl_error($crl));
    print_r('Curl error: ' . curl_error($crl));
}

curl_close($crl);
print_r($rest);

EDIT 1

To debug you can set CURLOPT_HEADER to true to check HTTP response with firebug::net or similar.

curl_setopt($crl, CURLOPT_HEADER, true);

EDIT 2

About Curl error: SSL certificate problem, verify that the CA cert is OK try adding this headers (just to debug, in a production enviroment you should keep these options in true):

curl_setopt($crl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($crl, CURLOPT_SSL_VERIFYPEER, false);

For 64-bit Use:

wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2

tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2

sudo mv wkhtmltopdf-amd64 /usr/bin/wkhtmltopdf

sudo chmod +x /usr/bin/wkhtmltopdf

Instead of searching fr the GUIDs, you can simply delete the GUIds tags. Then try opening the project again. The second time opening you should get a more reasonable error message.

For instance my issue was that I did not install SharePoint Developer Tools when I installed Visual Studio 2010 on my development Virtual Machine. So when I tried opennign the project after deleting the GUIDs, VS2010 told me the path it was looking for did not exist.

Therefore VS2010 was looking for a SharePoint library that was not installed. I simply had to run the install again, and then add that feature.

You can do this way, providing Json or Any other variable:

1) For exemple, in the controller, you can use Json.NET to provide Json to the ViewBag:

ViewBag.Number = 10;
ViewBag.FooObj = JsonConvert.SerializeObject(new Foo { Text = "Im a foo." });

2) In the View, put the script like this at the bottom of the page.

<script type="text/javascript">
    var number = parseInt(@ViewBag.Number); //Accessing the number from the ViewBag
    alert("Number is: " + number);
    var model = @Html.Raw(@ViewBag.FooObj); //Accessing the Json Object from ViewBag
    alert("Text is: " + model.Text);
</script> 

use

pattern.compile("\"");
String s= p.toString()+"yourcontent"+p.toString();

will give result as yourcontent as is

If you want certain element to completely loaded, Use ng-init on that element .

e.g. <div class="modal fade" id="modalFacultyInfo" role="dialog" ng-init="initModalFacultyInfo()"> ..</div>

the initModalFacultyInfo() function should exist in the controller.

Well, its not technically managing conflicts with submodules (ie: keep this but not that), but I found a way to continue working...and all I had to do was pay attention to my git status output and reset the submodules:

git reset HEAD subby
git commit

That would reset the submodule to the pre-pull commit. Which in this case is exactly what I wanted. And in other cases where I need the changes applied to the submodule, I'll handle those with the standard submodule workflows (checkout master, pull down the desired tag, etc).

Add multiple System.MailAdress object to get what you want.

It looks like you are trying to read an object from JSON that actually describes an array. Java objects are mapped to JSON objects with curly braces {} but your JSON actually starts with square brackets [] designating an array.

What you actually have is a List<product> To describe generic types, due to Java's type erasure, you must use a TypeReference. Your deserialization could read: myProduct = objectMapper.readValue(productJson, new TypeReference<List<product>>() {});

A couple of other notes: your classes should always be PascalCased. Your main method can just be public static void main(String[] args) throws Exception which saves you all the useless catch blocks.

http://localhost

The above host is already occupied by the emulator in which you are running the code. If you want to access the local host of your computer than use the IP Address as http://10.0.2.2:8080/.

For New versions

Older versions of python may not have pip installed and get-pip will throw errors. Please update your python (2.7.15 as of Aug 12, 2018).

All current versions have an option to install pip and add it to the path.

Steps:

1. Open Powershell as admin. (win+x then a)
2. Type python -m pip install <package>.

If python is not in PATH, it'll throw an error saying unrecognized cmd. To fix, simply add it to the path as mentioned below.

[OLD Answer]

Python 2.7 must be having pip pre-installed.

Try installing your package by:

1. Open cmd as admin. (win+x then a)
2. Go to scripts folder: C:\Python27\Scripts
3. Type pip install "package name".

Note: Else reinstall python: https://www.python.org/downloads/

Also note: You must be in C:\Python27\Scripts in order to use pip command, Else add it to your path by typing: [Environment]::SetEnvironmentVariable("Path","$env:Path;C:\Python27\;C:\Python27\Scripts\", "User")

If you have access to the Notepad++ editor on Windows there is a feature that allows you to easily get around this problem:

1. Open the file that's giving the error in Notepad++.
2. Go under the "Edit" Menu and choose "EOL Conversion"
3. There is an option there for "UNIX/OSX Format." Choose that option.
4. Re-save the file.

I did this and it solved my problems.

Hope this helps!

The real important difference is already mentioned in Chris' answer. However, the implications won't be obvious for everybody.

As an inline element, <span> may only contain other inline elements. The following code is therefore wrong:

<span><p>This is a paragraph</p></span>

The above code isn't valid. To wrap block-level elements, another block-level element must be used (such as <div>). On the other hand, <div> may only be used in places where block-level elements are legal.

Furthermore, these rules are fixed in (X)HTML and they are not altered by the presence of CSS rules! So the following codes are also wrong!

<span style="display: block"><p>Still wrong</p></span>
<span><p style="display: inline">Just as wrong</p></span>

You can always create an ArrayList of Objects. But it will not be very useful to you. Suppose you have created the Arraylist like this:

List<Object> myList = new ArrayList<Object>();

and add objects to this list like this:

myList.add(new Integer("5"));

myList.add("object");

myList.add(new Object());

You won't face any problem while adding and retrieving the object but it won't be very useful. You have to remember at what location each type of object is it in order to use it. In this case after retrieving, all you can do is calling the methods of Object on them.

An alternative solution:

function numberWithSpaces(value, pattern) {_x000D_
  var i = 0,_x000D_
    phone = value.toString();_x000D_
  return pattern.replace(/#/g, _ => phone[i++]);_x000D_
}_x000D_
_x000D_
console.log(numberWithSpaces('2124771000', '###-###-####'));

Great answer from atrain, but maybe better solution to catch exceptions is to utilize own HandlerExceptionResolver and catch

@Override
public ModelAndView resolveException(
    HttpServletRequest aReq, 
    HttpServletResponse aRes,
    Object aHandler, 
    Exception anExc
){
    // ....
    if(anExc instanceof MethodArgumentNotValidException) // do your handle     error here
}

Then you're able to keep your handler as clean as possible. You don't need BindingResult, Model and SomeFormBean in myHandlerMethod anymore.

Consider the following servlet conf:

   <servlet>
        <servlet-name>NewServlet</servlet-name>
        <servlet-class>NewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>NewServlet</servlet-name>
        <url-pattern>/NewServlet/*</url-pattern>
    </servlet-mapping>

Now, when I hit the URL http://localhost:8084/JSPTemp1/NewServlet/jhi, it will invoke NewServlet as it is mapped with the pattern described above.

Here:

getRequestURI() =  /JSPTemp1/NewServlet/jhi
getPathInfo() = /jhi

We have those ones:

• getPathInfo()

  returns
  a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information

• getRequestURI()

  returns
  a String containing the part of the URL from the protocol name up to the query string

I use a simple regex that extracts the host form the url:

function get_host(url){
    return url.replace(/^((\w+:)?\/\/[^\/]+\/?).*$/,'$1');
}

and use it like this

var url = 'http://www.sitename.com/article/2009/09/14/this-is-an-article/'
var host = get_host(url);

Note, if the url does not end with a / the host will not end in a /.

Here are some tests:

describe('get_host', function(){
    it('should return the host', function(){
        var url = 'http://www.sitename.com/article/2009/09/14/this-is-an-article/';
        assert.equal(get_host(url),'http://www.sitename.com/');
    });
    it('should not have a / if the url has no /', function(){
        var url = 'http://www.sitename.com';
        assert.equal(get_host(url),'http://www.sitename.com');
    });
    it('should deal with https', function(){
        var url = 'https://www.sitename.com/article/2009/09/14/this-is-an-article/';
        assert.equal(get_host(url),'https://www.sitename.com/');
    });
    it('should deal with no protocol urls', function(){
        var url = '//www.sitename.com/article/2009/09/14/this-is-an-article/';
        assert.equal(get_host(url),'//www.sitename.com/');
    });
    it('should deal with ports', function(){
        var url = 'http://www.sitename.com:8080/article/2009/09/14/this-is-an-article/';
        assert.equal(get_host(url),'http://www.sitename.com:8080/');
    });
    it('should deal with localhost', function(){
        var url = 'http://localhost/article/2009/09/14/this-is-an-article/';
        assert.equal(get_host(url),'http://localhost/');
    });
    it('should deal with numeric ip', function(){
        var url = 'http://192.168.18.1/article/2009/09/14/this-is-an-article/';
        assert.equal(get_host(url),'http://192.168.18.1/');
    });
});

Given

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

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

See svn diff in the manual:

svn diff -r 8979:11390 http://svn.collab.net/repos/svn/trunk/fSupplierModel.php

You can fill your data table like the below code.I am also fetching the connections at runtime using a predefined XML file that has all the connection.

  public static DataTable Execute_Query(string connection, string query)
    {
        Logger.Info("Execute Query has been called for connection " + connection);
        connection = "Data Source=" + Connections.run_singlevalue(connection, "server") + ";Initial Catalog=" + Connections.run_singlevalue(connection, "database") + ";User ID=" + Connections.run_singlevalue(connection, "username") + ";Password=" + Connections.run_singlevalue(connection, "password") + ";Connection Timeout=30;";
        DataTable dt = new DataTable();
        try
        {
            using (SqlConnection con = new SqlConnection(connection))
            {
                using (SqlCommand cmd = new SqlCommand(query, con))
                {
                    con.Open();
                    using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                    {
                        da.SelectCommand.CommandTimeout = 1800;
                        da.Fill(dt);
                    }
                    con.Close();
                }
            }
            Logger.Info("Execute Query success");
            return dt;
        }
        catch (Exception ex)
        {
            Console.Write(ex.Message);
            return null;
        }
    }   

The ALTER TABLE MySQL command should do the trick. The following command will change the default character set of your table and the character set of all its columns to UTF8.

ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

This command will convert all text-like columns in the table to the new character set. Character sets use different amounts of data per character, so MySQL will convert the type of some columns to ensure there's enough room to fit the same number of characters as the old column type.

I recommend you read the ALTER TABLE MySQL documentation before modifying any live data.

var firstNumber=5000,
secondeNumber=37;

var decimalResult = decimal.Divide(firstNumber,secondeNumber);

Console.WriteLine(decimalResult );

                $schema_insert .= "$row[$j]".$sep;
            else
                $schema_insert .= "".$sep;
        }
        $schema_insert = str_replace($sep."$", "", $schema_insert);
        $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);
        $schema_insert .= "\t";
        print(trim($schema_insert));
        print "\n";
    }   
?>

I think this may help you to resolve your problem.

To pass a pointer to an int it should be void Fun(int* pointer).

Passing a reference to an int would look like this...

void Fun(int& ref) {
   ref = 10;
}

int main() {
   int test = 5;
   cout << test << endl;  // prints 5

   Fun(test);
   cout << test << endl;  // prints 10 because Fun modified the value

   return 1;
}

How about Freebase? I think they have an API available, too.

http://www.freebase.com/

Here is something:

char const hex_chars[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F' };

for( int i = data; i < data_length; ++i )
{
    char const byte = data[i];

    string += hex_chars[ ( byte & 0xF0 ) >> 4 ];
    string += hex_chars[ ( byte & 0x0F ) >> 0 ];
}

>>> stuff = "Big and small"
>>> stuff.replace(" and ","/")
'Big/small'

It's possible to manually trigger events like this:

Apply the slider behavior to the element

var s = $('#slider').slider();

...

Set the slider value

s.slider('value',10);

Trigger the slide event, passing a ui object

s.trigger('slide',{ ui: $('.ui-slider-handle', s), value: 10 });

To send the data from one view controller (VC) to the other, use this simple approach:

YourNextVC *nxtScr = (YourNextVC*)[self.storyboard  instantiateViewControllerWithIdentifier:@"YourNextVC"];//Set this identifier from your storyboard

nxtScr.comingFrom = @"PreviousScreen"l
[self.navigationController nxtScr animated:YES];

Not all python modules are written in python. Datetime happens to be one of them that is not, and (on linux) is datetime.so.

You would have to download the source code to the python standard library to get at it.

It is very simple, just add a property:

public string Value {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

Using the Text property is a bit trickier, the UserControl class intentionally hides it. You'll need to override the attributes to put it back in working order:

[Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Bindable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public override string Text {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

Both approaches behave differently if you use a spied object (annotated with @Spy) instead of a mock (annotated with @Mock):

• when(...) thenReturn(...) makes a real method call just before the specified value will be returned. So if the called method throws an Exception you have to deal with it / mock it etc. Of course you still get your result (what you define in thenReturn(...))

• doReturn(...) when(...) does not call the method at all.

Example:

public class MyClass {
     protected String methodToBeTested() {
           return anotherMethodInClass();
     }

     protected String anotherMethodInClass() {
          throw new NullPointerException();
     }
}

Test:

@Spy
private MyClass myClass;

// ...

// would work fine
doReturn("test").when(myClass).anotherMethodInClass();

// would throw a NullPointerException
when(myClass.anotherMethodInClass()).thenReturn("test");

I believe this should work fine for any DataFrame columns list.

def column_list(x):
    column_list_df = []
    for col_name in x.columns:
        y = col_name, len(x[col_name].unique())
        column_list_df.append(y)
return pd.DataFrame(column_list_df)

column_list_df.rename(columns={0: "Feature", 1: "Value_count"})

The function "column_list" checks the columns names and then checks the uniqueness of each column values.

I use something like this

>>> import datetime
>>> regex = datetime.datetime.strptime
>>>
>>> # TEST
>>> assert regex('2020-08-03', '%Y-%m-%d')
>>>

>>> assert regex('2020-08', '%Y-%m-%d')
ValueError: time data '2020-08' does not match format '%Y-%m-%d'

>>> assert regex('08/03/20', '%m/%d/%y')
>>>

>>> assert regex('08-03-2020', '%m/%d/%y')
ValueError: time data '08-03-2020' does not match format '%m/%d/%y'

In my case, I needed to use something like this to keep the footer pinned down at the bottom if there is not much content, but not floating on top of everything constantly like data-position="fixed" seems to do...

.ui-content
{
    margin-bottom:75px; /* Set this to whatever your footer size is... */
}

.ui-footer {
    position: absolute !important;
    bottom: 0;
    width: 100%;
}

I did this;

In controller:

public ActionResult Index()
{
  var invoices = db.Invoices;

  var categories = db.Categories.ToList();
  ViewData["MyData"] = categories; // Send this list to the view

  return View(invoices.ToList());
}

In view:

@model IEnumerable<abc.Models.Invoice>

@{
    ViewBag.Title = "Invoices";
}

@{
  var categories = (List<Category>) ViewData["MyData"]; // Cast the list
}

@foreach (var c in @categories) // Print the list
{
  @Html.Label(c.Name);
}

<table>
    ...
    @foreach (var item in Model) 
    {
      ...
    }
</table>

Hope it helps

Uri myUri = Uri.parse("http://www.google.com");

Here's the doc http://developer.android.com/reference/android/net/Uri.html#parse%28java.lang.String%29

This probably harks from the old VB NOT .Net days when bool.ToString produced True or False.

What is happening here is that database route does not accept any url methods.

I would try putting the url methods in the app route just like you have in the entry_page function:

@app.route('/entry', methods=['GET', 'POST'])
def entry_page():
    if request.method == 'POST':
        date = request.form['date']
        title = request.form['blog_title']
        post = request.form['blog_main']
        post_entry = models.BlogPost(date = date, title = title, post = post)
        db.session.add(post_entry)
        db.session.commit()
        return redirect(url_for('database'))
    else:
        return render_template('entry.html')

@app.route('/database', methods=['GET', 'POST'])        
def database():
    query = []
    for i in session.query(models.BlogPost):
        query.append((i.title, i.post, i.date))
    return render_template('database.html', query = query)

Why not?

#header {
    text-align: center;
}

#header ul {
    display: inline;
}

Above queries are good for finding the amount of space used by the table (indexes included), but if you want to compare how much space is used by indexes on the table use this query:

SELECT
    OBJECT_NAME(i.OBJECT_ID) AS TableName,
    i.name AS IndexName,
    i.index_id AS IndexID,
    8 * SUM(a.used_pages) AS 'Indexsize(KB)'
FROM
    sys.indexes AS i
    JOIN sys.partitions AS p ON p.OBJECT_ID = i.OBJECT_ID AND p.index_id = i.index_id
    JOIN sys.allocation_units AS a ON a.container_id = p.partition_id
WHERE
    i.is_primary_key = 0 -- fix for size discrepancy
GROUP BY
    i.OBJECT_ID,
    i.index_id,
    i.name
ORDER BY
    OBJECT_NAME(i.OBJECT_ID),
    i.index_id

Google Apps Script is JavaScript, the date object is initiated with new Date() and all JavaScript methods apply, see doc here

If you're concerned the number of rows that meet the condition may change in the few milliseconds since execution of the query and retrieval of results, you could/should execute the queries inside a transaction:

BEGIN TRAN bogus

SELECT COUNT( my_table.my_col ) AS row_count
FROM my_table
WHERE my_table.foo = 'bar'

SELECT my_table.my_col
FROM my_table
WHERE my_table.foo = 'bar'
ROLLBACK TRAN bogus

This would return the correct values, always.

Furthermore, if you're using SQL Server, you can use @@ROWCOUNT to get the number of rows affected by last statement, and redirect the output of real query to a temp table or table variable, so you can return everything altogether, and no need of a transaction:

DECLARE @dummy INT

SELECT my_table.my_col
INTO #temp_table
FROM my_table
WHERE my_table.foo = 'bar'

SET @dummy=@@ROWCOUNT
SELECT @dummy, * FROM #temp_table

The data URI format is:

data:<headers>;<encoding>,<data>

So, you need only append your data to the "data:image/jpeg;," string:

var your_binary_data = document.body.innerText.replace(/(..)/gim,'%$1'); // parse text data to URI format

window.open('data:image/jpeg;,'+your_binary_data);

you can find the opencv_core248 and other dlls in opencv\build\x86\vc12\bin folder. Just copy the dlls you require into system32 folder. And your app should start working in a flash ! Hope it helps.

Display white space characters

Menu: You can toggle the visibility of the white space characters from the menu: Edit > Advanced > View White Space.

Button: If you want to add the button to a toolbar, it is called Toggle Visual Space in the command category "Edit".
The actual command name is: Edit.ViewWhiteSpace.

Keyboard Shortcut: In Visual Studio 2015, 2017 and 2019 the default keyboard shortcut still is CTRL+R, CTRL+W
Type one after the other.
All default shortcuts

End-of-line characters

Extension: There is a minimal extension adding the displaying of end-of-line characters (LF and CR) to the visual white space mode, as you would expect. Additionally it supplies buttons and short-cuts to modify all line-endings in a document, or a selection.
VisualStudio gallery: End of the Line

Note: Since Visual Studio 2017 there is no option in the File-menu called Advanced Save Options. Changing the encoding and line-endings for a file can be done using Save File As ... and clicking the down-arrow on the right side of the save-button. This shows the option Save with Encoding. You'll be asked permission to overwrite the current file.

The indentation is wrong, as the error tells you. As you can see, you have indented the code beginning with the indicated line too little to be in the for loop, but too much to be at the same level as the for loop. Python sees the lack of indentation as ending the for loop, then complains you have indented the rest of the code too much. (The def line I'm betting is just an artifact of how Stack Overflow wants you to format your code.)

Edit: Given your correction, I'm betting you have a mixture of tabs and spaces in the source file, such that it looks to the human eye like the code lines up, but Python considers it not to. As others have suggested, using only spaces is the recommended practice (see PEP 8). If you start Python with python -t, you will get warnings if there are mixed tabs and spaces in your code, which should help you pinpoint the issue.

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

Set column as unique in SQL Server from the GUI:

They really make you run around the barn to do it with the GUI:

Make sure your column does not violate the unique constraint before you begin.

1. Open SQL Server Management Studio.
2. Right click your Table, click "Design".
3. Right click the column you want to edit, a popup menu appears, click Indexes/Keys.
4. Click the "Add" Button.
5. Expand the "General" tab.
6. Make sure you have the column you want to make unique selected in the "columns" box.
7. Change the "Type" box to "Unique Key".
8. Click "Close".
9. You see a little asterisk in the file window, this means changes are not yet saved.
10. Press Save or hit Ctrl+s. It should save, and your column should be unique.

Or set column as unique from the SQL Query window:

alter table location_key drop constraint pinky;
alter table your_table add constraint pinky unique(yourcolumn);

Changes take effect immediately:

Try svn revert filename for every file you don't need and haven't yet committed. Or alternatively do svn revert -R folder for the problematic folder and then re-do the operation with correct ignoring configuration.

From the documentation:

 you can undo any scheduling operations:

$ svn add mistake.txt whoops
A         mistake.txt
A         whoops
A         whoops/oopsie.c

$ svn revert mistake.txt whoops
Reverted mistake.txt
Reverted whoops

Run this command after opening cmd as administrator

net start mssqlserver /T902

This command is called trace flag 902. It is used to bypass script upgrade mode. Every time when you try to start your sql service it also looks for script upgrades. and when the script upgrade fail your service unable to start. So, Whenever we have such upgrade script failure issue and SQL is not getting started, we need to use trace flag 902 to start SQL.

I hope this will help you..

If you really have to avoid operators then use Math.signum()

Returns the signum function of the argument; zero if the argument is zero, 1.0 if the argument is greater than zero, -1.0 if the argument is less than zero.

EDIT : As per the comments, this works for only double and float values. For integer values you can use the method:

Integer.signum(int i)

Remove <p></p> around the script.

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

iptables-restore < myfile and you're good to go.  

REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.

I am not sure if this applies to your situation, but I will post what worked for me.

I change my table view based on queries / searches to a database. For example, a database table contains Patient data. My initial table view in my program contains all Patients. I can then search query for Patients by firstName and lastName. I use the results of this query to repopulate my Observable list. Then I reset the items in the tableview by calling tableview.setItems(observableList):

/**
 * Searches the table for an existing Patient.
 */
@FXML
public void handleSearch() {
    String fname = this.fNameSearch.getText();
    String lname = this.lNameSearch.getText();
    LocalDate bdate = this.bDateSearch.getValue();

    if (this.nameAndDOBSearch(fname, lname, bdate)) {
        this.patientData = this.controller.processNursePatientSearch(fname, lname, bdate);
    } else if (this.birthDateSearch(fname, lname, bdate)) {
        this.patientData = this.controller.processNursePatientSearch(bdate);
    } else if (this.nameSearch(fname, lname, bdate)) {
        this.patientData = this.controller.processNursePatientSearch(fname, lname);
    }

    this.patientTable.setItems(this.patientData);
}

The if blocks update the ObservableList with the query results.

This should work with unsorted arrays, double values and different orders and length, while giving you the filtered values form array1, array2, or both.

function arrayDiff(arr1, arr2) {
    var diff = {};

    diff.arr1 = arr1.filter(function(value) {
        if (arr2.indexOf(value) === -1) {
            return value;
        }
    });

    diff.arr2 = arr2.filter(function(value) {
        if (arr1.indexOf(value) === -1) {
            return value;
        }
    });

    diff.concat = diff.arr1.concat(diff.arr2);

    return diff;
};

var firstArray = [1,2,3,4];
var secondArray = [4,6,1,4];

console.log( arrayDiff(firstArray, secondArray) );
console.log( arrayDiff(firstArray, secondArray).arr1 );
// => [ 2, 3 ]
console.log( arrayDiff(firstArray, secondArray).concat );
// => [ 2, 3, 6 ]

To get the last character of a string, you can use the split('').pop() function.

const myText = "The last character is J";
const lastCharater = myText.split('').pop();
console.log(lastCharater); // J

It's works because when the split('') function has empty('') as parameter, then each character of the string is changed to an element of an array. Thereby we can use the pop() function which returns the last element of that array, which is, the 'J' character.

If you need simplify code then live is better in the most cases. If you need to get the best performance then delegate will always better than live. bind (click) vs delegate isn't so simple question (if you have a lot of similar items then delegate will be better).

In main(), there is also:

return 0;

try

   System.Diagnostics.EventLog appLog = new System.Diagnostics.EventLog();
   appLog.Source = "This Application's Name";
   appLog.WriteEntry("An entry to the Application event log.");

If you are getting an error stating that "Object does not contain a definition for get_range."

Try following.

Excel.Worksheet sheet = workbook.ActiveSheet;
Excel.Range rng = (Excel.Range) sheet.Range[sheet.Cells[1, 1], sheet.Cells[3,3]].Cells;

In the "database" section of the logon dialog box, enter //hostname.domain:port/database, in your case //123.45.67.89:1521/TEST - this assumes that you don't want to set up a tnsnames.ora file/entry for some reason.

Also make sure the firewall settings on your server are not blocking port 1521.

Use this code

<?xml version="1.0" encoding="utf-8"?>

rather than doing complicated stuff, copy your repo (on your computer) to another place. delete the large file. do a couple of push and pull. Then some of your files will be messed up having things like "<<<<<< HEAD". Just copy your backup into the old folder on the disk. Do another add, commit, push!

This method is even easier if you're ok with fewer options:

FileCopy source, destination

You can also send an array via FormData this way:

var formData = new FormData;
var arr = ['this', 'is', 'an', 'array'];
for (var i = 0; i < arr.length; i++) {
    formData.append('arr[]', arr[i]);
}

So you can write arr[] the same way as you do it with a simple HTML form. In case of PHP it should work.

I am removing view using start and count Method, i have added 3 view in linear Layout.

view.removeViews(0, 3);

Here is an example comparing multiple angular-ui-router states using the OR || operator:

<li ng-class="
    {
        warning:
            $state.includes('out.pay.code.wrong')
            || $state.includes('out.pay.failed')
        ,
        active:
            $state.includes('out.pay')
    }
">

It will give the li the classes warning and/or active, depening on whether the conditions are met.

DAO (Data Access Object) is a very used design pattern in enterprise applications. It basically is the module that is used to access data from every source (DBMS, XML and so on). I suggest you to read some examples, like this one:

DAO Example

Please note that there are different ways to implements the original DAO Pattern, and there are many frameworks that can simplify your work. For example, the ORM (Object Relational Mapping) frameworks like iBatis or Hibernate, are used to map the result of SQL queries to java objects.

Hope it helps, Bye!

You can do it by making form and displaying it using ShowDialogBox....

Form.ShowDialog Method - Shows the form as a modal dialog box.

Example:

public void ShowMyDialogBox()
{
   Form2 testDialog = new Form2();

   // Show testDialog as a modal dialog and determine if DialogResult = OK.
   if (testDialog.ShowDialog(this) == DialogResult.OK)
   {
      // Read the contents of testDialog's TextBox.
      this.txtResult.Text = testDialog.TextBox1.Text;
   }
   else
   {
      this.txtResult.Text = "Cancelled";
   }
   testDialog.Dispose();
}

I had a similar problem and this is the workaround that helped me without having to edit the csv file contents:

If you have the flexibility to name the file something other than ".csv", you can name it with a ".txt" extension, such as "Myfile.txt" or "Myfile.csv.txt". Then when you open it in Excel (not by drag and drop, but using File->Open or the Most Recently Used files list), Excel will provide you with a "Text Import Wizard".

In the first page of the wizard, choose "Delimited" for the file type.

In the second page of the wizard choose "," as the delimiter and also choose the text qualifier if you have surrounded your values by quotes

In the third page, select every column individually and assign each the type "Text" instead of "General" to stop Excel from messing with your data.

Hope this helps you or someone with a similar problem!

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

It's really useful, I used it with a slight change:

filename=directory.list(new FilenameFilter() { 
    public boolean accept(File dir, String filename) { 
        return filename.startsWith(ipro); 
    }
});

I've done pablo solution and I always had the error (MVC4)

The view 'Error' or its master was not found or no view engine supports the searched location.

To get rid of this, remove the line

 filters.Add(new HandleErrorAttribute());

in FilterConfig.cs

Try this:

BufferedReader br = new BufferedReader(new FileReader("java_module_name/src/file_name.txt"));

Replace the "YOUR DATABASE NAME" in the query below.

    DECLARE @Database NVARCHAR(255)   
    DECLARE @Table NVARCHAR(255)  
    DECLARE @cmd NVARCHAR(1000)  

    DECLARE DatabaseCursor CURSOR READ_ONLY FOR  
    SELECT name FROM master.sys.databases   
    WHERE name IN ('YOUR DATABASE NAME')  -- databases
    AND state = 0 -- database is online
    AND is_in_standby = 0 -- database is not read only for log shipping
    ORDER BY 1  

    OPEN DatabaseCursor  

    FETCH NEXT FROM DatabaseCursor INTO @Database  
    WHILE @@FETCH_STATUS = 0  
    BEGIN  

       SET @cmd = 'DECLARE TableCursor CURSOR READ_ONLY FOR SELECT ''['' + table_catalog + ''].['' + table_schema + ''].['' +  
       table_name + '']'' as tableName FROM [' + @Database + '].INFORMATION_SCHEMA.TABLES WHERE table_type = ''BASE TABLE'''   

       -- create table cursor  
       EXEC (@cmd)  
       OPEN TableCursor   

       FETCH NEXT FROM TableCursor INTO @Table   
       WHILE @@FETCH_STATUS = 0   
       BEGIN
          BEGIN TRY   
             SET @cmd = 'ALTER INDEX ALL ON ' + @Table + ' REBUILD' 
             PRINT @cmd -- uncomment if you want to see commands
             EXEC (@cmd) 
          END TRY
          BEGIN CATCH
             PRINT '---'
             PRINT @cmd
             PRINT ERROR_MESSAGE() 
             PRINT '---'
          END CATCH

          FETCH NEXT FROM TableCursor INTO @Table   
       END   

       CLOSE TableCursor   
       DEALLOCATE TableCursor  

       FETCH NEXT FROM DatabaseCursor INTO @Database  
    END  
    CLOSE DatabaseCursor   
    DEALLOCATE DatabaseCursor

This worked for me...

If you are using windows...

Search 'cmd' in the windows search bar.

Enter this:C:\xampp\apache\bin\httpd.exe

Find which file and which line the error occurred.

For example, mine was in the file below on line 37.

httpd-multilang-errordoc.conf

Open the code and fix the error by either removing the line or fixing it.

Done! I should work now.

Quick Overview: index and find

Next to the find method there is as well index. find and index both yield the same result: returning the position of the first occurrence, but if nothing is found index will raise a ValueError whereas find returns -1. Speedwise, both have the same benchmark results.

s.find(t)    #returns: -1, or index where t starts in s
s.index(t)   #returns: Same as find, but raises ValueError if t is not in s

Additional knowledge: rfind and rindex:

In general, find and index return the smallest index where the passed-in string starts, and rfind and rindex return the largest index where it starts Most of the string searching algorithms search from left to right, so functions starting with r indicate that the search happens from right to left.

So in case that the likelihood of the element you are searching is close to the end than to the start of the list, rfind or rindex would be faster.

s.rfind(t)   #returns: Same as find, but searched right to left
s.rindex(t)  #returns: Same as index, but searches right to left

print_r($_GET['color']);

or

var_dump($_GET['color']);

One command and does not use the destructive git reset command:

GIT_SEQUENCE_EDITOR="sed -i 's/pick/d/'" git rebase -i HEAD~ --autostash

It simply drops the commit, putting you back exactly in the state before the cherry-pick even if you had local changes.

Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.

First considerations are about mixing HTML, Javascript and CSS:

Why is using onClick() in HTML a bad practice?

Unobtrusive Javascript

Inline Styles vs Classes

I will be removing inline content and splitting these into their appropriate files.

Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.

Your function changeBackground sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.

CSS

#TheForm {
    margin-left: 396px;
}
#submitColor {
    margin-left: 48px;
    margin-top: 5px;
}

HTML

<form id="TheForm">
    <input id="color" type="text" />
    <br/>
    <input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>

Javascript

function changeBackground() {
    var color = document.getElementById("color").value; // cached

    // The working function for changing background color.
    document.bgColor = color;

    // The code I'd like to use for changing the text simultaneously - however it does not work.
    document.getElementById("coltext").style.color = color;
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

Color Values

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.

Update: as pointed out by @Ian

Hex can be either 3 or 6 characters long

Source: W3C

Numerical color values

The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.

Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.

For regex testing, I will use this pattern

/^#(?:[0-9a-f]{3}){1,2}$/i

but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern

function changeBackground() {
    var color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;

    if (rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Hex Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

Here is a further modification that will allow colours by name along with by hex.

function changeBackground() {
    var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
        color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
        formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();

    if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Color");
    }
}

This would do it:

$("#header ul").append('<li><a href="/user/messages"><span class="tab">Message Center</span></a></li>');

Two things:

• You can just append the <li> to the <ul> itself.
• You need to use the opposite type of quotes than what you're using in your HTML. So since you're using double quotes in your attributes, surround the code with single quotes.

Available and Condition

<target name="check-abc">
    <available file="abc.txt" property="abc.present"/>
</target>

<target name="do-if-abc" depends="check-abc" if="abc.present">
    ...
</target> 

json works with Unicode text in Python 3 (JSON format itself is defined only in terms of Unicode text) and therefore you need to decode bytes received in HTTP response. r.headers.get_content_charset('utf-8') gets your the character encoding:

#!/usr/bin/env python3
import io
import json
from urllib.request import urlopen

with urlopen('https://httpbin.org/get') as r, \
     io.TextIOWrapper(r, encoding=r.headers.get_content_charset('utf-8')) as file:
    result = json.load(file)
print(result['headers']['User-Agent'])

It is not necessary to use io.TextIOWrapper here:

#!/usr/bin/env python3
import json
from urllib.request import urlopen

with urlopen('https://httpbin.org/get') as r:
    result = json.loads(r.read().decode(r.headers.get_content_charset('utf-8')))
print(result['headers']['User-Agent'])

Let's just say you have 3 buttons:

<input type="button" disabled="disabled" value="hello world">
<input type="button" disabled value="hello world">
<input type="button" value="hello world">

To style the disabled button you can use the following css:

input[type="button"]:disabled{
    color:#000;
}

This will only affect the button which is disabled.

To stop the color changing when hovering you can use this too:

input[type="button"]:disabled:hover{
    color:#000;
}

You can also avoid this by using a css-reset.

Code Safety Note

Regarding the accepted answer, it is important to use toSerialize.GetType() instead of typeof(T) in XmlSerializer constructor: if you use the first one the code covers all possible scenarios, while using the latter one fails sometimes.

Here is a link with some example code that motivate this statement, with XmlSerializer throwing an Exception when typeof(T) is used, because you pass an instance of a derived type to a method that calls SerializeObject<T>() that is defined in the derived type's base class: http://ideone.com/1Z5J1. Note that Ideone uses Mono to execute code: the actual Exception you would get using the Microsoft .NET runtime has a different Message than the one shown on Ideone, but it fails just the same.

For the sake of completeness I post the full code sample here for future reference, just in case Ideone (where I posted the code) becomes unavailable in the future:

using System;
using System.Xml.Serialization;
using System.IO;

public class Test
{
    public static void Main()
    {
        Sub subInstance = new Sub();
        Console.WriteLine(subInstance.TestMethod());
    }

    public class Super
    {
        public string TestMethod() {
            return this.SerializeObject();
        }
    }

    public class Sub : Super
    {
    }
}

public static class TestExt {
    public static string SerializeObject<T>(this T toSerialize)
    {
        Console.WriteLine(typeof(T).Name);             // PRINTS: "Super", the base/superclass -- Expected output is "Sub" instead
        Console.WriteLine(toSerialize.GetType().Name); // PRINTS: "Sub", the derived/subclass

        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        StringWriter textWriter = new StringWriter();

        // And now...this will throw and Exception!
        // Changing new XmlSerializer(typeof(T)) to new XmlSerializer(subInstance.GetType()); 
        // solves the problem
        xmlSerializer.Serialize(textWriter, toSerialize);
        return textWriter.ToString();
    }
}

In the model, do not pass the value:

timezone.now()

Rather, remove the parenthesis, and pass:

timezone.now

If you continue to get a runtime error warning, consider changing the model field from DateTimeField to DateField.

By default maven does not include any files from "src/main/java".

You have two possible way to that.

1. put all your resource files (different than java files) to "src/main/resources" - this is highly recommended

2. Add to your pom (resource plugin):

?

 <resources>
       <resource>
           <directory>src/main/resources</directory>
        </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
  </resources>

If you haven't already committed your changes, just use git checkout to move to the new branch and then commit them normally - changes to files are not tied to a particular branch until you commit them.

If you have already committed your changes:

1. Type git log and remember the SHA of the commit you want to move.
2. Check out the branch you want to move the commit to.
3. Type git cherry-pick SHA substituting the SHA from above.
4. Switch back to your original branch.
5. Use git reset HEAD~1 to reset back before your wrong-branch commit.

cherry-pick takes a given commit and applies it to the currently checked-out head, thus allowing you to copy the commit over to a new branch.

In Java 8 a new class named Instant is introduced. As per doc:

Instant represents the start of a nanosecond on the time line. This class is useful for generating a time stamp to represent machine time. The range of an instant requires the storage of a number larger than a long. To achieve this, the class stores a long representing epoch-seconds and an int representing nanosecond-of-second, which will always be between 0 and 999,999,999. The epoch-seconds are measured from the standard Java epoch of 1970-01-01T00:00:00Z where instants after the epoch have positive values, and earlier instants have negative values. For both the epoch-second and nanosecond parts, a larger value is always later on the time-line than a smaller value.

This can be used as:

Instant start = Instant.now();
try {
    Thread.sleep(7000);
} catch (InterruptedException e) {
    e.printStackTrace();
}
Instant end = Instant.now();
System.out.println(Duration.between(start, end));

It prints PT7.001S.

On windows use the name of the table in quotes: TABLE "user"; or SELECT * FROM "user";

Following is simple method to generate specific length verification code. Length can be specified, by default, it generates 4 digit code.

function get_sms_token($length = 4) {

    return rand(
        ((int) str_pad(1, $length, 0, STR_PAD_RIGHT)),
        ((int) str_pad(9, $length, 9, STR_PAD_RIGHT))
    );
}

echo get_sms_token(6);

There is plenty of good answer to this question. Just gonna drop another one into the basket if you wish to do it with lolcat

A percentage value in a height property has a little complication, and the width and height properties actually behave differently to each other. Let me take you on a tour through the specs.

height property:

Let's have a look at what CSS Snapshot 2010 spec says about height:

The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'. A percentage height on the root element is relative to the initial containing block. Note: For absolutely positioned elements whose containing block is based on a block-level element, the percentage is calculated with respect to the height of the padding box of that element.

OK, let's take that apart step by step:

The percentage is calculated with respect to the height of the generated box's containing block.

What's a containing block? It's a bit complicated, but for a normal element in the default static position, it's:

the nearest block container ancestor box

or in English, its parent box. (It's well worth knowing what it would be for fixed and absolute positions as well, but I'm ignoring that to keep this answer short.)

So take these two examples:

<div   id="a"  style="width: 100px; height: 200px; background-color: orange">_x000D_
  <div id="aa" style="width: 100px; height: 50%;   background-color: blue"></div>_x000D_
</div>

<div   id="b"  style="width: 100px;              background-color: orange">_x000D_
  <div id="bb" style="width: 100px; height: 50%; background-color: blue"></div>_x000D_
</div>

In this example, the containing block of #aa is #a, and so on for #b and #bb. So far, so good.

The next sentence of the spec for height is the complication I mentioned in the introduction to this answer:

If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.

Aha! Whether the height of the containing block has been specified explicitly matters!

• 50% of height:200px is 100px in the case of #aa
• But 50% of height:auto is auto, which is 0px in the case of #bb since there is no content for auto to expand to

As the spec says, it also matters whether the containing block has been absolutely positioned or not, but let's move on to width.

width property:

So does it work the same way for width? Let's take a look at the spec:

The percentage is calculated with respect to the width of the generated box's containing block.

Take a look at these familiar examples, tweaked from the previous to vary width instead of height:

<div   id="c"  style="width: 200px; height: 100px; background-color: orange">_x000D_
  <div id="cc" style="width: 50%;   height: 100px; background-color: blue"></div>_x000D_
</div>

<div   id="d"  style="            height: 100px; background-color: orange">_x000D_
  <div id="dd" style="width: 50%; height: 100px; background-color: blue"></div>_x000D_
</div>

• 50% of width:200px is 100px in the case of #cc
• 50% of width:auto is 50% of whatever width:auto ends up being, unlike height, there is no special rule that treats this case differently.

Now, here's the tricky bit: auto means different things, depending partly on whether its been specified for width or height! For height, it just meant the height needed to fit the contents*, but for width, auto is actually more complicated. You can see from the code snippet that's in this case it ended up being the width of the viewport.

What does the spec say about the auto value for width?

The width depends on the values of other properties. See the sections below.

Wahey, that's not helpful. To save you the trouble, I've found you the relevant section to our use-case, titled "calculating widths and margins", subtitled "block-level, non-replaced elements in normal flow":

The following constraints must hold among the used values of the other properties:

'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' = width of containing block

OK, so width plus the relevant margin, border and padding borders must all add up to the width of the containing block (not descendents the way height works). Just one more spec sentence:

If 'width' is set to 'auto', any other 'auto' values become '0' and 'width' follows from the resulting equality.

Aha! So in this case, 50% of width:auto is 50% of the viewport. Hopefully everything finally makes sense now!

_Footnotes

_{* At least, as far it matters in this case. spec All right, everything only kind of makes sense now.}

You will use the following query:

SELECT * FROM [table] GROUP BY NUMBER;

Where [table] is the name of the table.

This provides a unique listing for the NUMBER column however the other columns may be meaningless depending on the vendor implementation; which is to say they may not together correspond to a specific row or rows.

Because timedelta is defined like:

class datetime.timedelta([days,] [seconds,] [microseconds,] [milliseconds,] [minutes,] [hours,] [weeks])

All arguments are optional and default to 0.

You can easily say "Three days and four milliseconds" with optional arguments that way.

>>> datetime.timedelta(days=3, milliseconds=4)
datetime.timedelta(3, 0, 4000)
>>> datetime.timedelta(3, 0, 0, 4) #no need for that.
datetime.timedelta(3, 0, 4000)

And for str casting, it returns a nice formatted value instead of __repr__ to improve readability. From docs:

str(t) Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t. (5)

>>> datetime.timedelta(seconds = 42).__repr__()
'datetime.timedelta(0, 42)'
>>> datetime.timedelta(seconds = 42).__str__()
'0:00:42'

Pandas 0.23+

Use pandas.Series.dt.day_name(), since pandas.Timestamp.weekday_name has been deprecated:

import pandas as pd


df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])

df['day_of_week'] = df['my_dates'].dt.day_name()

Output:

    my_dates  myvals day_of_week
0 2015-01-01       1    Thursday
1 2015-01-02       2      Friday
2 2015-01-03       3    Saturday

Pandas 0.18.1+

As user jezrael points out below, dt.weekday_name was added in version 0.18.1 Pandas Docs

import pandas as pd

df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])
df['day_of_week'] = df['my_dates'].dt.weekday_name

Output:

    my_dates  myvals day_of_week
0 2015-01-01       1    Thursday
1 2015-01-02       2      Friday
2 2015-01-03       3    Saturday

Original Answer:

Use this:

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.dt.dayofweek.html

See this:

Get weekday/day-of-week for Datetime column of DataFrame

If you want a string instead of an integer do something like this:

import pandas as pd

df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])
df['day_of_week'] = df['my_dates'].dt.dayofweek

days = {0:'Mon',1:'Tues',2:'Weds',3:'Thurs',4:'Fri',5:'Sat',6:'Sun'}

df['day_of_week'] = df['day_of_week'].apply(lambda x: days[x])

Output:

    my_dates  myvals day_of_week
0 2015-01-01       1       Thurs
1 2015-01-02       2         Fri
2 2015-01-01       3       Thurs

I prefer joda for date and time arithmetics because it is much better readable:

Date tomorrow = now().plusDays(1).toDate();

Or

endOfDay(now().plus(days(1))).toDate()
startOfDay(now().plus(days(1))).toDate()

I would really recommend anyone entering this subject to read Addy Osmani's free book:

"Learning JavaScript Design Patterns".

http://addyosmani.com/resources/essentialjsdesignpatterns/book/

This book helped me out immensely when I was starting into writing more maintainable JavaScript and I still use it as a reference. Have a look at his different module pattern implementations, he explains them really well.

Firstly: The >>> code you see in python examples is a way to indicate that it is Python code. It's used to separate Python code from output. Like this:

>>> 4+5
9

Here we see that the line that starts with >>> is the Python code, and 9 is what it results in. This is exactly how it looks if you start a Python interpreter, which is why it's done like that.

You never enter the >>> part into a .py file.

That takes care of your syntax error.

Secondly, ctypes is just one of several ways of wrapping Python libraries. Other ways are SWIG, which will look at your Python library and generate a Python C extension module that exposes the C API. Another way is to use Cython.

They all have benefits and drawbacks.

SWIG will only expose your C API to Python. That means you don't get any objects or anything, you'll have to make a separate Python file doing that. It is however common to have a module called say "wowza" and a SWIG module called "_wowza" that is the wrapper around the C API. This is a nice and easy way of doing things.

Cython generates a C-Extension file. It has the benefit that all of the Python code you write is made into C, so the objects you write are also in C, which can be a performance improvement. But you'll have to learn how it interfaces with C so it's a little bit extra work to learn how to use it.

ctypes have the benefit that there is no C-code to compile, so it's very nice to use for wrapping standard libraries written by someone else, and already exists in binary versions for Windows and OS X.

If you want your container to have it's own virtual ethernet socket (with it's own MAC address), iptables, then use the Macvlan driver. This may be necessary to route traffic out to your/ISPs router.

https://docs.docker.com/engine/userguide/networking/get-started-macvlan

If your constraint is on a user type, then don't forget to see if there is a Default Constraint, usually something like DF__TableName__ColumnName__6BAEFA67, if so then you will need to drop the Default Constraint, like this:

ALTER TABLE TableName DROP CONSTRAINT [DF__TableName__ColumnName__6BAEFA67]

For more info see the comments by the brilliant Aaron Bertrand on this answer.

For other readers, the error can come from the fact that there is no brackets wrapping the async function:

Considering the async function initData

  async function initData() {
  }

This code will lead to your error:

  useEffect(() => initData(), []);

But this one, won't:

  useEffect(() => { initData(); }, []);

(Notice the brackets around initData()

function redir(data) {_x000D_
  document.getElementById('redirect').innerHTML = '<form style="display:none;" position="absolute" method="post" action="location.php"><input id="redirbtn" type="submit" name="value" value=' + data + '></form>';_x000D_
  document.getElementById('redirbtn').click();_x000D_
}

<button onclick="redir('dataToBeSent');">Next Page</button>_x000D_
<div id="redirect"></div>

You can use this method which creates a new hidden form whose "data" is sent by "post" to "location.php" when a button[Next Page] is clicked.

@Swapnil Niwane

I was able to solve this issue by calling an ajax request and formatting the data to 'jsonp'.

$.ajax({
          method: 'GET',
          url: url,
          defaultHeaders: {
              'Content-Type': 'application/json',
              "Access-Control-Allow-Origin": "*",
              'Accept': 'application/json'
           },

          dataType: 'jsonp',

          success: function (response) {
            console.log("success ");
            console.log(response);
          },
          error: function (xhr) {
            console.log("error ");
            console.log(xhr);
          }
});

If the row you want to delete might change you can use this. Just pass this function the row # you wish to delete.

function removeMyRow(docRowCount){
   $('table tr').eq(docRowCount).remove();
}

This is a tool that will help you, i installed it myself

You need the /g for global matching

replace(/\n/g, "<br />");

This works for me for \n - see this answer if you might have \r\n

NOTE: The dupe is the most complete answer for any combination of \r\n, \r or \n

var messagetoSend = document.getElementById('x').value.replace(/\n/g, "<br />");_x000D_
console.log(messagetoSend);

UPDATE

It seems some visitors of this question have text with the breaklines escaped as

some text\r\nover more than one line"

In that case you need to escape the slashes:

replace(/\\r\\n/g, "<br />");

NOTE: All browsers will ignore \r in a string when rendering.

f = open('data.txt','r')
string = ""
while 1:
    line = f.readline()
    if not line:break
    string += line

f.close()


print(string)

Adding this option for dealing with basic uint8 to byte[] conversion

foo := 255 // 1 - 255
ufoo := uint16(foo) 
far := []byte{0,0}
binary.LittleEndian.PutUint16(far, ufoo)
bar := int(far[0]) // back to int
fmt.Println("foo, far, bar : ",foo,far,bar)

output : foo, far, bar : 255 [255 0] 255

To replace easily all 1 with 10 in a = [1,2,3,4,5,1,2,3,4,5,1]one could use the following one-line lambda+map combination, and 'Look, Ma, no IFs or FORs!' :

# This substitutes all '1' with '10' in list 'a' and places result in list 'c':

c = list(map(lambda b: b.replace("1","10"), a))

Use:

vector<vector<float>> vecArray; //both dimensions are open!

Here is a detailed answer.

del can be used for any class object whereas pop and remove and bounded to specific classes.

For del

Here are some examples

>>> a = 5
>>> b = "this is string"
>>> c = 1.432
>>> d = myClass()

>>> del c
>>> del a, b, d   # we can use comma separated objects

We can override __del__ method in user-created classes.

Specific uses with list

>>> a = [1, 4, 2, 4, 12, 3, 0]
>>> del a[4]
>>> a
[1, 4, 2, 4, 3, 0]

>>> del a[1: 3]   # we can also use slicing for deleting range of indices
>>> a
[1, 4, 3, 0]

For pop

pop takes the index as a parameter and removes the element at that index

Unlike del, pop when called on list object returns the value at that index

>>> a = [1, 5, 3, 4, 7, 8]
>>> a.pop(3)  # Will return the value at index 3
4
>>> a
[1, 5, 3, 7, 8]

For remove

remove takes the parameter value and remove that value from the list.

If multiple values are present will remove the first occurrence

Note: Will throw ValueError if that value is not present

>>> a = [1, 5, 3, 4, 2, 7, 5]
>>> a.remove(5)  # removes first occurence of 5
>>> a
[1, 3, 4, 2, 7, 5]
>>> a.remove(5)
>>> a
[1, 3, 4, 2, 7]

Hope this answer is helpful.

If increasing max_allowed_packet doesn't help.

I was getting the same error as you when importing a .sql file into my database via Sequel Pro.

The error still persisted after upping the max_allowed_packet to 512M so I ran the import in the command line instead with:

mysql --verbose -u root -p DatabaseName < MySQL.sql

It gave the following error:

ASCII '\0' appeared in the statement, but this is not allowed unless option --binary-mode is enabled

I found a couple helpful StackOverflow questions:

• Enable binary mode while restoring a Database from an SQL dump
• Mysql ERROR: ASCII '\0' while importing sql file on linux server

In my case, my .sql file was a little corrupt or something. The MySQL dump we get comes in two zip files that need to be concatenated together and then unzipped. I think the unzipping was interrupted initially, leaving the file with some odd characters and encodings. Getting a fresh MySQL dump and unzipping it properly worked for me.

Just wanted to add this here in case others find that increasing the max_allowed_packet variable was not helping.

The main benefit of using LDAP is that information for an entire organization can be consolidated into a central repository. For example, rather than managing user lists for each group within an organization, LDAP can be used as a central directory accessible from anywhere on the network. And because LDAP supports Secure Sockets Layer (SSL) and Transport Layer Security (TLS), sensitive data can be protected from prying eyes.

LDAP also supports a number of back-end databases in which to store directories. This allows administrators the flexibility to deploy the database best suited for the type of information the server is to disseminate. Because LDAP also has a well-defined client Application Programming Interface (API), the number of LDAP-enabled applications are numerous and increasing in quantity and quality.

#include ...

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QGraphicsScene scene;
    QGraphicsView view(&scene);
    QGraphicsPixmapItem item(QPixmap("c:\\test.png"));
    scene.addItem(&item);
    view.show();
    return a.exec();
}

This should work. :) List of supported formats can be found here

Try something like:

from tkinter import Tk, Button, Frame, Entry, END

class ABC(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.pack()        

root = Tk()
app = ABC(master=root)
app.master.title("Simple Prog")
app.mainloop()
root.destroy()

Now you should have a frame with a title, then afterwards you can add windows for different widgets if you like.

When working on a project that requires the use of multiple dockerfiles, simply create each dockerfile in a separate directory. For instance,

app/ db/

Each of the above directories will contain their dockerfile. When an application is being built, docker will search all directories and build all dockerfiles.

You can use varStatus in your c:forEach loop

In your first example you can get the counter to work properly as follows...

<c:forEach var="tableEntity" items='${requestScope.tables}'>
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="count">            
        my count is ${count.count}
    </c:forEach>
</c:forEach>

According to this: http://www.vistax64.com/vista-installation-setup/33219-regsvr32-error-0x80004005.html

Run it in a elevated command prompt.

Maybe you could take a look at function QUOTE in the MySQL manual.
