Programs & Examples On #Msmq transaction

Try with this combination of Lambda expressions:

employees.ToList().ForEach(emp => 
{
    collection.AddRange(emp.Departments);
    emp.Departments.ToList().ForEach(dept => dept.SomeProperty = null);                    
});

You need the /g (global) option, like this:

var replaced = str.replace(/ /g, '+');

You can give it a try here. Unlike most other languages, JavaScript, by default, only replaces the first occurrence.

UPDATE tbl_ClientNotes 
SET ordering=@ordering, title=@title, content=@content 
WHERE id=@id 
AND @ordering IS NOT NULL
AND @title IS NOT NULL
AND @content IS NOT NULL

Or if you meant you only want to update individual columns you would use the post above mine. I read it as do not update if any values are null

Rda is just a short name for RData. You can just save(), load(), attach(), etc. just like you do with RData.

Rds stores a single R object. Yet, beyond that simple explanation, there are several differences from a "standard" storage. Probably this R-manual Link to readRDS() function clarifies such distinctions sufficiently.

So, answering your questions:

• The difference is not about the compression, but serialization (See this page)
• Like shown in the manual page, you may wanna use it to restore a certain object with a different name, for instance.
• You may readRDS() and save(), or load() and saveRDS() selectively.

List<String> l = new ArrayList<String>(listOfTopicAuthors);

try doing str.replace(/[^\w]/); It will replace all the non-alphabets and numbers from your string!

Edit 1: str.replace(/[^\w]/g, ' ')

If jQuery's error handler is being called and the XHR object contains "parser error", that's probably a parser error coming back from the server.

Is your multiple result scenario when you call the service without a parameter, but it's breaking when you try to supply a parameter to retrieve the single record?

What backend are you returning this from?

On ASMX services, for example, that's often the case when parameters are supplied to jQuery as a JSON object instead of a JSON string. If you provide jQuery an actual JSON object for its "data" parameter, it will serialize that into standard & delimited k,v pairs instead of sending it as JSON.

You can utilize the fact that the character encodings for digits are all in order from 48 (for '0') to 57 (for '9'). This holds true for ASCII, UTF-x and practically all other encodings (see comments below for more on this).

Therefore the integer value for any digit is the digit minus '0' (or 48).

char c = '1';
int i = c - '0'; // i is now equal to 1, not '1'

is synonymous to

char c = '1';
int i = c - 48; // i is now equal to 1, not '1'

However I find the first c - '0' far more readable.

This also happens if the paths are correct, but the service account is not the owner of the data files (yet it still has enough rights for read/write access). This can occur if the permissions for the files were reset to match the permissions of the folder (of course, while the service was stopped).

The easiest solution in this case is to detach each database and attach it again (because when attaching the owner is changed to be the service account).

A php file is run whenever you access it via an HTTP request be it GET,POST, PUT.

You can use JQuery/Ajax to send a request on a button click, or even just change the URL of the browser to navigate to the php address.

Depending on the data sent in the POST/GET you can have a switch statement running a different function.

Specifying Function via GET

You can utilize the code here: How to call PHP function from string stored in a Variable along with a switch statement to automatically call the appropriate function depending on data sent.

So on PHP side you can have something like this:

<?php

//see http://php.net/manual/en/function.call-user-func-array.php how to use extensively
if(isset($_GET['runFunction']) && function_exists($_GET['runFunction']))
call_user_func($_GET['runFunction']);
else
echo "Function not found or wrong input";

function test()
{
echo("test");
}

function hello()
{
echo("hello");
}

?>

and you can make the simplest get request using the address bar as testing:

http://127.0.0.1/test.php?runFunction=hellodddddd

results in:

Function not found or wrong input

http://127.0.0.1/test.php?runFunction=hello

results in:

hello

Sending the Data

GET Request via JQuery

See: http://api.jquery.com/jQuery.get/

$.get("test.cgi", { name: "John"})
.done(function(data) {
  alert("Data Loaded: " + data);
});

POST Request via JQuery

See: http://api.jquery.com/jQuery.post/

$.post("test.php", { name: "John"} );

GET Request via Javascript location

See: http://www.javascripter.net/faq/buttonli.htm

Use GREATEST()

E.g.:

SELECT GREATEST(2,1);

Note: Whenever if any single value contains null at that time this function always returns null (Thanks to user @sanghavi7)

Well, for your sample and any with a limited number of unique columns, this should do it.

select 
    distinct a,
    (select distinct t2.b  from t t2  where t1.a=t2.a and t2.b='VIEW'),
    (select distinct t2.b from t t2  where t1.a=t2.a and t2.b='EDIT')
from t t1

To consider multiple column.

Sort and give unique list based on column 1 and column 3:

sort -u -t : -k 1,1 -k 3,3 test.txt

• -t : colon is separator
• -k 1,1 -k 3,3 based on column 1 and column 3

In English:

• ContentType: When sending data to the server, use this content type. Default is application/x-www-form-urlencoded; charset=UTF-8, which is fine for most cases.
• Accepts: The content type sent in the request header that tells the server what kind of response it will accept in return. Depends on DataType.
• DataType: The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response. Can be text, xml, html, script, json, jsonp.

Javascript always passes by value. However, if you pass an object to a function, the "value" is really a reference to that object, so the function can modify that object's properties but not cause the variable outside the function to point to some other object.

An example:

function changeParam(x, y, z) {
  x = 3;
  y = "new string";
  z["key2"] = "new";
  z["key3"] = "newer";

  z = {"new" : "object"};
}

var a = 1,
    b = "something",
    c = {"key1" : "whatever", "key2" : "original value"};

changeParam(a, b, c);

// at this point a is still 1
// b is still "something"
// c still points to the same object but its properties have been updated
// so it is now {"key1" : "whatever", "key2" : "new", "key3" : "newer"}
// c definitely doesn't point to the new object created as the last line
// of the function with z = ...

According to the following article: https://www.percona.com/blog/2007/08/28/to-sql_calc_found_rows-or-not-to-sql_calc_found_rows/

If you have an INDEX on your where clause (if id is indexed in your case), then it is better not to use SQL_CALC_FOUND_ROWS and use 2 queries instead, but if you don't have an index on what you put in your where clause (id in your case) then using SQL_CALC_FOUND_ROWS is more efficient.

There is an input:focus as there is a textarea:focus

input:focus { 
    outline: none !important;
    border-color: #719ECE;
    box-shadow: 0 0 10px #719ECE;
}
textarea:focus { 
    outline: none !important;
    border-color: #719ECE;
    box-shadow: 0 0 10px #719ECE;
}

Your elements need to have a position attribute. (e.g. absolute, relative, fixed) or z-index won't work.

Working with a dictionary ->level2 above comes from a dictionary in my case (just in case anybody will find it useful) Trying the first example I stumbled over this error: "This document already has a 'DocumentElement' node." I was inspired by the answer here

and edited my code: (xmlDoc.DocumentElement.AppendChild(body))

//a dictionary:
Dictionary<string, string> Level2Data 
{
    {"level2", "text"},
    {"level2", "other text"},
    {"same_level2", "more text"}
}
//xml Decalration:
XmlDocument xmlDoc = new XmlDocument();
XmlDeclaration xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);
XmlElement root = xmlDoc.DocumentElement;
xmlDoc.InsertBefore(xmlDeclaration, root);
// add body
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.AppendChild(body);
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.DocumentElement.AppendChild(body); //without DocumentElement ->ERR



foreach (KeyValuePair<string, string> entry in Level2Data)
{
    //write to xml: - it works version 1.
    XmlNode keyNode = xmlDoc.CreateElement(entry.Key); //open TAB
    keyNode.InnerText = entry.Value;
    body.AppendChild(keyNode); //close TAB

    //Write to xmml verdion 2: (uncomment the next 4 lines and comment the above 3 - version 1
    //XmlElement key = xmlDoc.CreateElement(string.Empty, entry.Key, string.Empty);
    //XmlText value = xmlDoc.CreateTextNode(entry.Value);
    //key.AppendChild(value);
    //body.AppendChild(key);
}

Both versions (1 and 2 inside foreach loop) give the output:

<?xml version="1.0" encoding="UTF-8"?>
<body>
    <level1>
        <level2>text</level2>
        <level2>ther text</level2>
         <same_level2>more text</same_level2>
    </level1>
</body>

(Note: third line "same level2" in dictionary can be also level2 as the others but I wanted to ilustrate the advantage of the dictionary - in my case I needed level2 with different names.

This can also happen because github has recently renamed the default branch from "master" to "main" ( https://github.com/github/renaming ), so if you just created a new repository on github use git push origin main instead of git push origin master

Using jQuery:

$('#play-pause').click(function(){
  if ( $('#video-over').css('visibility') == 'hidden' )
    $('#video-over').css('visibility','visible');
  else
    $('#video-over').css('visibility','hidden');
});

 function integerDivison(dividend, divisor){
    
        this.Division  = dividend/divisor;
        this.Quotient = Math.floor(dividend/divisor);
         this.Remainder = dividend%divisor;
        this.calculate = ()=>{
            return {Value:this.Division,Quotient:this.Quotient,Remainder:this.Remainder};
        }
         
    }

  var divide = new integerDivison(5,2);
  console.log(divide.Quotient)      //to get Quotient of two value 
  console.log(divide.division)     //to get Floating division of two value 
  console.log(divide.Remainder)     //to get Remainder of two value 
  console.log(divide.calculate())   //to get object containing all the values

You can do this is just 3 simple step that i used.

1) make new branch where you want to commit you recent update.

git branch <branch name>

2) Find Recent Commit Id for commit on new branch.

git log

3) Copy that commit id note that Most Recent commit list take place on top. so you can find your commit. you also find this via message.

git cherry-pick d34bcef232f6c...

you can also provide some rang of commit id.

git cherry-pick d34bcef...86d2aec

Now your job done. If you picked correct id and correct branch then you will success. So before do this be careful. else another problem can occur.

Now you can push your code

git push

This one worked for me

RESHARPER > OPTIONS > select visual studio (Under Keyboard Shortcuts)

Try:

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

JSP/Servlet 2.4 (I think that's the version number) doesn't support method calls in EL and only support properties. The latest servlet containers do support method calls (ie Tomcat 7).

First Context (can be Activity/Service etc)

For Service, you need to override onStartCommand there you have direct access to intent:

Override
public int onStartCommand(Intent intent, int flags, int startId) {

You have a few options:

1) Use the Bundle from the Intent:

Intent mIntent = new Intent(this, Example.class);
Bundle extras = mIntent.getExtras();
extras.putString(key, value);  

2) Create a new Bundle

Intent mIntent = new Intent(this, Example.class);
Bundle mBundle = new Bundle();
mBundle.extras.putString(key, value);
mIntent.putExtras(mBundle);

3) Use the putExtra() shortcut method of the Intent

Intent mIntent = new Intent(this, Example.class);
mIntent.putExtra(key, value);

New Context (can be Activity/Service etc)

Intent myIntent = getIntent(); // this getter is just for example purpose, can differ
if (myIntent !=null && myIntent.getExtras()!=null)
     String value = myIntent.getExtras().getString(key);
}

NOTE: Bundles have "get" and "put" methods for all the primitive types, Parcelables, and Serializables. I just used Strings for demonstrational purposes.

In the SQL-92 Standard, COUNT(*) specifically means "the cardinality of the table expression" (could be a base table, `VIEW, derived table, CTE, etc).

I guess the idea was that COUNT(*) is easy to parse. Using any other expression requires the parser to ensure it doesn't reference any columns (COUNT('a') where a is a literal and COUNT(a) where a is a column can yield different results).

In the same vein, COUNT(*) can be easily picked out by a human coder familiar with the SQL Standards, a useful skill when working with more than one vendor's SQL offering.

Also, in the special case SELECT COUNT(*) FROM MyPersistedTable;, the thinking is the DBMS is likely to hold statistics for the cardinality of the table.

Therefore, because COUNT(1) and COUNT(*) are semantically equivalent, I use COUNT(*).

Pure CSS solution:

.inputfile {_x000D_

  opacity: 0;_x000D_
  overflow: hidden;_x000D_
  position: absolute;_x000D_

Best practices on internal and external temporary files:

Internal Cache

If you'd like to cache some data, rather than store it persistently, you should use getCacheDir() to open a File that represents the internal directory where your application should save temporary cache files.

When the device is low on internal storage space, Android may delete these cache files to recover space. However, you should not rely on the system to clean up these files for you. You should always maintain the cache files yourself and stay within a reasonable limit of space consumed, such as 1MB. When the user uninstalls your application, these files are removed.

External Cache

To open a File that represents the external storage directory where you should save cache files, call getExternalCacheDir(). If the user uninstalls your application, these files will be automatically deleted.

Similar to ContextCompat.getExternalFilesDirs(), mentioned above, you can also access a cache directory on a secondary external storage (if available) by calling ContextCompat.getExternalCacheDirs().

Tip: To preserve file space and maintain your app's performance, it's important that you carefully manage your cache files and remove those that aren't needed anymore throughout your app's lifecycle.

To compare with an int do this:

<?php
$date = date("m");
$dateToCompareTo = 05;
if (strval($date) == strval($dateToCompareTo)) {
    echo "They are the same";
}
?>

By setting activity theme in Manifest,

<activity
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
....
>

Raw HTML is actually perfectly valid in markdown. For instance:

Normal *markdown* paragraph.

<p class="myclass">This paragraph has a class "myclass"</p>

Just make sure the HTML is not inside a code block.

Does document.getElementById("blue") exist? if it doesn't then blue_box will be equal to null. you can't set a onclick on something that's null

Jobs.aspx

This is the phyiscal file -> CodeFile="Jobs.aspx.cs"

This is the class which handles the events of the page -> Inherits="Members_Jobs"

Jobs.aspx.cs

This is the partial class which manages the page events -> public partial class Members_Jobs : System.Web.UI.Page

The other part of the partial class should be -> public partial class Members_Jobs this is usually the designer file.

you dont need to have partial classes and could declare your controls all in 1 class and not have a designer file.

EDIT 27/09/2013 11:37

if you are still having issues with this I would do as Bharadwaj suggested and delete the designer file. You can then right-click on the page, in the solution explorer, and there is an option, something like "Convert to Web Application", which will regenerate your designer file

private static final int TAKE_PICTURE = 1;    
private Uri imageUri;

public void takePhoto(View view) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
    intent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(photo));
    imageUri = Uri.fromFile(photo);
    startActivityForResult(intent, TAKE_PICTURE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
    case TAKE_PICTURE:
        if (resultCode == Activity.RESULT_OK) {
            Uri selectedImage = imageUri;
            getContentResolver().notifyChange(selectedImage, null);
            ImageView imageView = (ImageView) findViewById(R.id.ImageView);
            ContentResolver cr = getContentResolver();
            Bitmap bitmap;
            try {
                 bitmap = android.provider.MediaStore.Images.Media
                 .getBitmap(cr, selectedImage);

                imageView.setImageBitmap(bitmap);
                Toast.makeText(this, selectedImage.toString(),
                        Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
                        .show();
                Log.e("Camera", e.toString());
            }
        }
    }
}

Here's a more complete and flexible example that doesn't omit necessary includes to generate compilation errors:

#include <iostream>
#include <unordered_map>

class Hashtable {
    std::unordered_map<const void *, const void *> htmap;

public:
    void put(const void *key, const void *value) {
            htmap[key] = value;
    }

    const void *get(const void *key) {
            return htmap[key];
    }

};

int main() {
    Hashtable ht;
    ht.put("Bob", "Dylan");
    int one = 1;
    ht.put("one", &one);
    std::cout << (char *)ht.get("Bob") << "; " << *(int *)ht.get("one");
}

Still not particularly useful for keys, unless they are predefined as pointers, because a matching value won't do! (However, since I normally use strings for keys, substituting "string" for "const void *" in the declaration of the key should resolve this problem.)

Here is a single line that will create (or overwrite) the file:

File.Create("C:\my files\2010\SomeFileName.txt").Dispose()

Note: calling Dispose() ensures that the reference to the file is closed.

It provides nothing else but a standardization of the data. The values it creates are known under several different names, one of them being z-scores ("Z" because the normal distribution is also known as the "Z distribution").

More can be found here:

http://en.wikipedia.org/wiki/Standard_score

cat `cat filenames.txt`

will do the trick

First add the # -*- coding: utf-8 -*- line to the beginning of the file and then use u'foo' for all your non-ASCII unicode data:

def NewFunction():
    return u'£'

or use the magic available since Python 2.6 to make it automatic:

from __future__ import unicode_literals

Declare them before the while loop.

$hn = "";
$pid = "";
$datereg = "";
$prefix = "";
$fname = "";
$lname = "";
$age = "";
$sex = "";

You are getting the notice because the variables are declared and assigned inside the loop.

[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*

This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.

    select v.SQL_TEXT,
           v.PARSING_SCHEMA_NAME,
           v.FIRST_LOAD_TIME,
           v.DISK_READS,
           v.ROWS_PROCESSED,
           v.ELAPSED_TIME,
           v.service
      from v$sql v
where to_date(v.FIRST_LOAD_TIME,'YYYY-MM-DD hh24:mi:ss')>ADD_MONTHS(trunc(sysdate,'MM'),-2)

where clause is optional. You can sort the results according to FIRST_LOAD_TIME and find the records up to 2 months ago.

Must be too late now, but the right version would be:

for(var i = 0; i < restaurants.restaurant.length; i++)
{
  if(restaurants.restaurant[i].food == 'chicken')
  {
    return restaurants.restaurant[i].name;
  }
}

Assume time column is in timestamp integer msec format

1 day = 86400000 ms

Here you go:

day_divider = 86400000

df['time'] = df['time'].values.astype(dtype='datetime64[ms]') # for msec format

df['time'] = (df['time']/day_divider).values.astype(dtype='datetime64[D]') # for day format

I'm a little late, but, since some time ago in TypeScript you can define the type of callback with

type MyCallback = (KeyboardEvent) => void;

Example of use:

this.addEvent(document, "keydown", (e) => {
    if (e.keyCode === 1) {
      e.preventDefault();
    }
});

addEvent(element, eventName, callback: MyCallback) {
    element.addEventListener(eventName, callback, false);
}

Only one change was needed to fix the problem:

Go to Start -> Control Panel -> System -> Advanced(tab) -> Environment Variables -> System Variables

set ANDROID_HOME to C:\Program Files (x86)\Android\android-sdk

To remove line breaks using Python you can use replace function of a string.

This example removes all 3 types of line breaks:

my_string = open('lala.json').read()
print(my_string)

my_string = my_string.replace("\r","").replace("\n","")
print(my_string)

Example file is:

{
  "lala": "lulu",
  "foo": "bar"
}

You can try it using this replay scenario:

I tried this and things got weird for me. (css stopped working after the :after {content: "";} part of this tutorial. I found you can color the bullets by just using color:#ddd; on the li item itself.

Here's an example.

li{
    color:#ff0000;    
    list-style:square;                
}
a {
    text-decoration: none;
    color:#00ff00;
}

a:hover {
    background-color: #ddd;
}

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

Try this After open web.config file in application and add sample db connection in connectionStrings section like this

<connectionStrings>
<add name="yourconnectinstringName" connectionString="Data Source= DatabaseServerName; Integrated Security=true;Initial Catalog= YourDatabaseName; uid=YourUserName; Password=yourpassword; " providerName="System.Data.SqlClient"/>
</connectionStrings >

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

unset is not actually a function, but a language construct. It is no more a function call than a return or an include.

Aside from performance issues, using unset makes your code's intent much clearer.

Tthe problems may be caused by incorrect mapping. Are you sure you have your result set in "data"? In my example, the backend code returns results under "items" key, so the mapping should look like:

results: $.map(data.items, function (item) {
....
}

and not:

 results: $.map(data, function (item) {
    ....
    }

I was looking for a snippet of code that would do something similar to help with writing unit test. Here is what I ended up using.

public static bool PublicInstancePropertiesEqual<T>(T self, T to, params string[] ignore) where T : class 
  {
     if (self != null && to != null)
     {
        Type type = typeof(T);
        List<string> ignoreList = new List<string>(ignore);
        foreach (System.Reflection.PropertyInfo pi in type.GetProperties(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance))
        {
           if (!ignoreList.Contains(pi.Name))
           {
              object selfValue = type.GetProperty(pi.Name).GetValue(self, null);
              object toValue = type.GetProperty(pi.Name).GetValue(to, null);

              if (selfValue != toValue && (selfValue == null || !selfValue.Equals(toValue)))
              {
                 return false;
              }
           }
        }
        return true;
     }
     return self == to;
  }

EDIT:

Same code as above but uses LINQ and Extension methods :

public static bool PublicInstancePropertiesEqual<T>(this T self, T to, params string[] ignore) where T : class
{
    if (self != null && to != null)
    {
        var type = typeof(T);
        var ignoreList = new List<string>(ignore);
        var unequalProperties =
            from pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance)
            where !ignoreList.Contains(pi.Name) && pi.GetUnderlyingType().IsSimpleType() && pi.GetIndexParameters().Length == 0
            let selfValue = type.GetProperty(pi.Name).GetValue(self, null)
            let toValue = type.GetProperty(pi.Name).GetValue(to, null)
            where selfValue != toValue && (selfValue == null || !selfValue.Equals(toValue))
            select selfValue;
        return !unequalProperties.Any();
    }
    return self == to;
}

            case MemberTypes.Method:
               return ((MethodInfo)member).ReturnType;
            case MemberTypes.Property:
               return ((PropertyInfo)member).PropertyType;
            default:

               (
                  "Input MemberInfo must be if type EventInfo, FieldInfo, MethodInfo, or PropertyInfo"

This is the way to execute remote script with passing to it some arguments (arg1 arg2):

curl -s http://server/path/script.sh | bash /dev/stdin arg1 arg2

You accidentally created the column name with a trailing space and presumably phpPGadmin created the column name with double quotes around it:

create table your_table (
    "foo " -- ...
)

That would give you a column that looked like it was called foo everywhere but you'd have to double quote it and include the space whenever you use it:

select ... from your_table where "foo " is not null

The best practice is to use lower case unquoted column names with PostgreSQL. There should be a setting in phpPGadmin somewhere that will tell it to not quote identifiers (such as table and column names) but alas, I don't use phpPGadmin so I don't where that setting is (or even if it exists).

The note is firstly you must sure about filemode set to false in config git file, or use this command:

git config core.filemode false

and then you can set 0777 permission with this command:

git update-index --chmod=+x foo.sh

info frame to show the stack frame info

To read the memory at given addresses you should take a look at x

x/x $esp for hex x/d $esp for signed x/u $esp for unsigned etc. x uses the format syntax, you could also take a look at the current instruction via x/i $eip etc.

Assuming ASCII strings:

string1 = 'Hello'
string2 = 'hello'

if string1.lower() == string2.lower():
    print("The strings are the same (case insensitive)")
else:
    print("The strings are NOT the same (case insensitive)")

You can't change CSS properties directly with jQuery. But you can achieve the same effect in at least two ways.

Dynamically Load CSS from a File

function updateStyleSheet(filename) {
    newstylesheet = "style_" + filename + ".css";

    if ($("#dynamic_css").length == 0) {
        $("head").append("<link>")
        css = $("head").children(":last");

        css.attr({
          id: "dynamic_css",
          rel:  "stylesheet",
          type: "text/css",
          href: newstylesheet
        });
    } else {
        $("#dynamic_css").attr("href",newstylesheet);
    }
}

The example above is copied from:

• How To Switch CSS Files On-The-Fly Using jQuery

Dynamically Add a Style Element

$("head").append('<style type="text/css"></style>');
var newStyleElement = $("head").children(':last');
newStyleElement.html('.red{background:green;}');

The example code is copied from this JSFiddle fiddle originally referenced by Alvaro in their comment.

WORKING Method { if there is no problem other than configuration }

By Default Appache is not restricting access from ipv4. (common external ip)

What may restrict is the configurations in 'httpd.conf' (or 'apache2.conf' depending on your apache configuration)

Solution:

Replace all:

<Directory />
     AllowOverride none
    Require all denied

</Directory>

with

<Directory />
     AllowOverride none
#    Require all denied

</Directory>

hence removing out all restriction given to Apache

Replace Require local with Require all granted at C:/wamp/www/ directory

<Directory "c:/wamp/www/">
    Options Indexes FollowSymLinks
    AllowOverride all
    Require all granted
#   Require local
</Directory>

with BytesIO() as output:
    from PIL import Image
    with Image.open(filename) as img:
        img.convert('RGB').save(output, 'BMP')                
    data = output.getvalue()[14:]

I just use this for add a image to clipboard in windows.

Update: angular2-cookie is now deprecated. Please use my ngx-cookie instead.

Old answer:

Here is angular2-cookie which is the exact implementation of Angular 1 $cookies service (plus a removeAll() method) that I created. It is using the same methods, only implemented in typescript with Angular 2 logic.

You can inject it as a service in the components providers array:

import {CookieService} from 'angular2-cookie/core';

@Component({
    selector: 'my-very-cool-app',
    template: '<h1>My Angular2 App with Cookies</h1>',
    providers: [CookieService]
})

After that, define it in the consturctur as usual and start using:

export class AppComponent { 
  constructor(private _cookieService:CookieService){}

  getCookie(key: string){
    return this._cookieService.get(key);
  }
}

You can get it via npm:

npm install angular2-cookie --save

use this code

 knob.bind('mousewheel', function(e){  
 if(e.originalEvent.wheelDelta < 0) {
    moveKnob('down');
  } else {
    moveKnob('up');
 }
  return false;
});

Addendum to the original query: modules.py

help('modules')

$python modules.py

It lists that module bs4 already been installed.

_codecs_kr          blinker             json                six
_codecs_tw          brotli              kaitaistruct        smtpd
_collections        bs4                 keyword             smtplib
_collections_abc    builtins            ldap3               sndhdr
_compat_pickle      bz2                 lib2to3             socket

Proper solution is:

pip install --upgrade bs4

Should solve the problem.

Not only that, it will show same error for other modules as well. So you got to issue the pip command same way as above for those errored module(s).

public delegate void ThingToTryDeletage();

public static void TryNTimes(ThingToTryDelegate, int N, int sleepTime)
{
   while(true)
   {
      try
      {
        ThingToTryDelegate();
      } catch {

            if( --N == 0) throw;
          else Thread.Sleep(time);          
      }
}

You need to check out the attr method in the jQuery docs. You are misusing it. What you are doing within the if statements simply replaces all image tags src with the string specified in the 2nd parameter.

http://api.jquery.com/attr/

A better way to approach replacing a series of images source would be to loop through each and check it's source.

Example:

$('img').each(function () {
  var curSrc = $(this).attr('src');
  if ( curSrc === 'http://example.com/smith.gif' ) {
      $(this).attr('src', 'http://example.com/johnson.gif');
  }
  if ( curSrc === 'http://example.com/williams.gif' ) {
      $(this).attr('src', 'http://example.com/brown.gif');
  }
});

I would use:

CAST
(
CAST(YEAR(DATEFIELD) as varchar(4)) + '/' CAST(MM(DATEFIELD) as varchar(2)) + '/' CAST(DD(DATEFIELD) as varchar(2)) as datetime
) 

Thus effectively creating a new field from the date field you already have.

For Python 2.7 and Pandas 0.24.2 and using Psycopg2

Psycopg2 Connection Module

def dbConnect (db_parm, username_parm, host_parm, pw_parm):
    # Parse in connection information
    credentials = {'host': host_parm, 'database': db_parm, 'user': username_parm, 'password': pw_parm}
    conn = psycopg2.connect(**credentials)
    conn.autocommit = True  # auto-commit each entry to the database
    conn.cursor_factory = RealDictCursor
    cur = conn.cursor()
    print ("Connected Successfully to DB: " + str(db_parm) + "@" + str(host_parm))
    return conn, cur

Connect to the database

conn, cur = dbConnect(databaseName, dbUser, dbHost, dbPwd)

Assuming dataframe to be present already as df

output = io.BytesIO() # For Python3 use StringIO
df.to_csv(output, sep='\t', header=True, index=False)
output.seek(0) # Required for rewinding the String object
copy_query = "COPY mem_info FROM STDOUT csv DELIMITER '\t' NULL ''  ESCAPE '\\' HEADER "  # Replace your table name in place of mem_info
cur.copy_expert(copy_query, output)
conn.commit()

timeout-decorator don't work on windows system as , windows didn't support signal well.

If you use timeout-decorator in windows system you will get the following

AttributeError: module 'signal' has no attribute 'SIGALRM'

Some suggested to use use_signals=False but didn't worked for me.

Author @bitranox created the following package:

pip install https://github.com/bitranox/wrapt-timeout-decorator/archive/master.zip

Code Sample:

import time
from wrapt_timeout_decorator import *

@timeout(5)
def mytest(message):
    print(message)
    for i in range(1,10):
        time.sleep(1)
        print('{} seconds have passed'.format(i))

def main():
    mytest('starting')


if __name__ == '__main__':
    main()

Gives the following exception:

TimeoutError: Function mytest timed out after 5 seconds

The problem with both iDevlop's and Ashok's answers is that the fundamental problem is an Excel design flaw (apparently) in which the Open method fails to respect the Application.ScreenUpdating setting of False. Consequently, setting it to False is of no benefit to this problem.

If Patrick McDonald's solution is too burdensome due to the overhead of starting a second instance of Excel, then the best solution I've found is to minimize the time that the opened workbook is visible by re-activating the original window as quickly as possible:

Dim TempWkBk As Workbook
Dim CurrentWin As Window

Set CurrentWin = ActiveWindow
Set TempWkBk = Workbooks.Open(SomeFilePath)
CurrentWin.Activate      'Allows only a VERY brief flash of the opened workbook
TempWkBk.Windows(1).Visible = False 'Only necessary if you also need to prevent
                                    'the user from manually accessing the opened
                                    'workbook before it is closed.

'Operate on the new workbook, which is not visible to the user, then close it...

iOS Status bar has only 2 options (black and white). You can try this in AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
}

Try this:

CASE WHEN table3.col3 IS NULL THEN table2.col3 ELSE table3.col3 END as col4

The as col4 should go at the end of the CASE the statement. Also note that you're missing the END too.

Another probably more simple option would be:

IIf([table3.col3] Is Null,[table2.col3],[table3.col3])

Just to clarify, MS Access does not support COALESCE. If it would that would be the best way to go.

Edit after radical question change:

To turn the query into SQL Server then you can use COALESCE (so it was technically answered before too):

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
COALESCE(dbo.EU_Admin3.EUID, dbo.EU_Admin2.EUID)
FROM dbo.AdminID

BTW, your CASE statement was missing a , before the field. That's why it didn't work.

You didn't specify how the order is determined, but this will give you a rank value in MySQL:

SELECT t.*,
       @rownum := @rownum +1 AS rank
  FROM TBL_FOO t
  JOIN (SELECT @rownum := 0) r
 WHERE t.name = 'sarmen'

Then you can pick out what rows you want, based on the rank value.

You are probably looking for the DATEDIFF function.

DATEDIFF ( datepart , startdate , enddate )

Where you code might look like this:

DATEDIFF ( hh , startdate , enddate )

Here's something that will print any sort of nested dictionary, while keeping track of the "parent" dictionaries along the way.

dicList = list()

def prettierPrint(dic, dicList):
count = 0
for key, value in dic.iteritems():
    count+=1
    if str(value) == 'OrderedDict()':
        value = None
    if not isinstance(value, dict):
        print str(key) + ": " + str(value)
        print str(key) + ' was found in the following path:',
        print dicList
        print '\n'
    elif isinstance(value, dict):
        dicList.append(key)
        prettierPrint(value, dicList)
    if dicList:
         if count == len(dic):
             dicList.pop()
             count = 0

prettierPrint(dicExample, dicList)

This is a good starting point for printing according to different formats, like the one specified in OP. All you really need to do is operations around the Print blocks. Note that it looks to see if the value is 'OrderedDict()'. Depending on whether you're using something from Container datatypes Collections, you should make these sort of fail-safes so the elif block doesn't see it as an additional dictionary due to its name. As of now, an example dictionary like

example_dict = {'key1': 'value1',
            'key2': 'value2',
            'key3': {'key3a': 'value3a'},
            'key4': {'key4a': {'key4aa': 'value4aa',
                               'key4ab': 'value4ab',
                               'key4ac': 'value4ac'},
                     'key4b': 'value4b'}

will print

key3a: value3a
key3a was found in the following path: ['key3']

key2: value2
key2 was found in the following path: []

key1: value1
key1 was found in the following path: []

key4ab: value4ab
key4ab was found in the following path: ['key4', 'key4a']

key4ac: value4ac
key4ac was found in the following path: ['key4', 'key4a']

key4aa: value4aa
key4aa was found in the following path: ['key4', 'key4a']

key4b: value4b
key4b was found in the following path: ['key4']

~altering code to fit the question's format~

lastDict = list()
dicList = list()
def prettierPrint(dic, dicList):
    global lastDict
    count = 0
    for key, value in dic.iteritems():
        count+=1
        if str(value) == 'OrderedDict()':
            value = None
        if not isinstance(value, dict):
            if lastDict == dicList:
                sameParents = True
            else:
                sameParents = False

            if dicList and sameParents is not True:
                spacing = ' ' * len(str(dicList))
                print dicList
                print spacing,
                print str(value)

            if dicList and sameParents is True:
                print spacing,
                print str(value)
            lastDict = list(dicList)

        elif isinstance(value, dict):
            dicList.append(key)
            prettierPrint(value, dicList)

        if dicList:
             if count == len(dic):
                 dicList.pop()
                 count = 0

Using the same example code, it will print the following:

['key3']
         value3a
['key4', 'key4a']
                  value4ab
                  value4ac
                  value4aa
['key4']
         value4b

This isn't exactly what is requested in OP. The difference is that a parent^n is still printed, instead of being absent and replaced with white-space. To get to OP's format, you'll need to do something like the following: iteratively compare dicList with the lastDict. You can do this by making a new dictionary and copying dicList's content to it, checking if i in the copied dictionary is the same as i in lastDict, and -- if it is -- writing whitespace to that i position using the string multiplier function.

Instead of worrying about every single apostrophe in your statement. You can easily use the q' Notation.

Example

SELECT q'(Alex's Tea Factory)' FROM DUAL;

Key Components in this notation are

• q' which denotes the starting of the notation
• ( an optional symbol denoting the starting of the statement to be fully escaped.
• Alex's Tea Factory (Which is the statement itself)
• )' A closing parenthesis with a apostrophe denoting the end of the notation.

And such that, you can stuff how many apostrophes in the notation without worrying about each single one of them, they're all going to be handled safely.

IMPORTANT NOTE

Since you used ( you must close it with )', and remember it's optional to use any other symbol, for instance, the following code will run exactly as the previous one

SELECT q'[Alex's Tea Factory]' FROM DUAL;

Addressing @Niklas R's comment to @nickanor's answer:

from urllib.error import HTTPError
import urllib.request

def getResponseCode(url):
    try:
        conn = urllib.request.urlopen(url)
        return conn.getcode()
    except HTTPError as e:
        return e.code

Use local-web-server npm package.

https://www.npmjs.com/package/local-web-server

$ npm install -g local-web-server
$ cd <your-app-folder>
$ ws

Also, you can run

$ ws -p 8181

-p defines the port you want to use

After that, just go to your browser and access http:localhost:8181/

The first argument should be the path to the executable program. So

gdb progname 12271

I have built a mashup of existing answers to simplify everything and reduce the amount of code needed for Swift 3.

func hmsFrom(seconds: Int, completion: @escaping (_ hours: Int, _ minutes: Int, _ seconds: Int)->()) {

        completion(seconds / 3600, (seconds % 3600) / 60, (seconds % 3600) % 60)

}

func getStringFrom(seconds: Int) -> String {

    return seconds < 10 ? "0\(seconds)" : "\(seconds)"
}

Usage:

var seconds: Int = 100

hmsFrom(seconds: seconds) { hours, minutes, seconds in

    let hours = getStringFrom(seconds: hours)
    let minutes = getStringFrom(seconds: minutes)
    let seconds = getStringFrom(seconds: seconds)

    print("\(hours):\(minutes):\(seconds)")                
}

Prints:

00:01:40

Yes, marquee_forever also work in case of fixed width for TextView. (e.g. android:layout_width="120dp")

Must required attributes are:

1. android:focusable="true"
2. android:focusableInTouchMode="true"
3. android:singleLine="true" // if it's missing text appear in multiple line.

Working code:

<TextView
                android:id="@+id/mediaTitleTV"
                android:layout_width="220dp"
                android:layout_height="wrap_content"
                android:ellipsize="marquee"
                android:focusable="true"
                android:focusableInTouchMode="true"
                android:marqueeRepeatLimit="marquee_forever"
                android:singleLine="true"
                android:text="Try Marquee, it works with fixed size textview smoothly!" />

convert to Array

var array = like.ToArray();
var first = array[0];

<a class="menu_links" onclick="displayData(11,1,0,'A')" onmouseover="" style="cursor: pointer;"> A </a>

It's css.

Or in a style sheet:

a.menu_links { cursor: pointer; }

Hide response header and then add a new custom header value

Adding a header with add_header works fine with proxy pass, but if there is an existing header value in the response it will stack the values.

If you want to set or replace a header value (for example replace the Access-Control-Allow-Origin header to match your client for allowing cross origin resource sharing) then you can do as follows:

# 1. hide the Access-Control-Allow-Origin from the server response
proxy_hide_header Access-Control-Allow-Origin;
# 2. add a new custom header that allows all * origins instead
add_header Access-Control-Allow-Origin *;

So proxy_hide_header combined with add_header gives you the power to set/replace response header values.

Similar answer can be found here on ServerFault

UPDATE:

Note: proxy_set_header is for setting request headers before the request is sent further, not for setting response headers (these configuration attributes for headers can be a bit confusing).

If you just want to print a double with two digits after the decimal point, use something like this:

double value = 200.3456;
System.out.printf("Value: %.2f", value);

If you want to have the result in a String instead of being printed to the console, use String.format() with the same arguments:

String result = String.format("%.2f", value);

Or use class DecimalFormat:

DecimalFormat df = new DecimalFormat("####0.00");
System.out.println("Value: " + df.format(value));

CMD:

reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
reg query HKEY_CURRENT_USER\Environment

PowerShell:

Get-Item "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Get-Item HKCU:\Environment

Powershell/.NET: (see EnvironmentVariableTarget Enum)

[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::Machine)
[System.Environment]::GetEnvironmentVariables([System.EnvironmentVariableTarget]::User)

You are doing it right. The empty code block is what is causing your issue. It's not the condition structure :)

DECLARE @StartDate AS DATETIME

DECLARE @EndDate AS DATETIME

SET @StartDate = NULL
SET @EndDate = NULL

IF (@StartDate IS NOT NULL AND @EndDate IS NOT NULL) 
    BEGIN
        print 'yoyoyo'
    END

IF (@StartDate IS NULL AND @EndDate IS NULL AND 1=1 AND 2=2) 
    BEGIN
        print 'Oh hey there'
    END

Here it may helps you: create a file field in your models.py

For uploading the file(in your admin.py):

def save_model(self, request, obj, form, change):
    url = "http://img.youtube.com/vi/%s/hqdefault.jpg" %(obj.video)
    url = str(url)

    if url:
        temp_img = NamedTemporaryFile(delete=True)
        temp_img.write(urllib2.urlopen(url).read())
        temp_img.flush()
        filename_img = urlparse(url).path.split('/')[-1]
        obj.image.save(filename_img,File(temp_img)

and use that field in your template also.

Oneliner:

obj = (function(attr, val){ var a = {}; a[attr]=val; return a; })('hash', 5);

Or:

attr = 'hash';
val = 5;
var obj = (obj={}, obj[attr]=val, obj);

Anything shorter?

In my case the "Fix Issue" button triggers a spinner for about 20 seconds and fixes nothing.

This works for me (iOS 7 iPhone 5, Xcode 5):

Xcode > Window > Organizer > Devices

Find the connected device(with a green dot) on the left pane. Select "Provisioning Profiles" On the right pane, there is a line with warning. Delete this line.

Now go back to click the "Fix Issue" button and everything is fine - the app runs in the device as expected.

The typical way to send binary in json is to base64 encode it.

Java provides different ways to Base64 encode and decode a byte[]. One of these is DatatypeConverter.

Very simply

byte[] originalBytes = new byte[] { 1, 2, 3, 4, 5};
String base64Encoded = DatatypeConverter.printBase64Binary(originalBytes);
byte[] base64Decoded = DatatypeConverter.parseBase64Binary(base64Encoded);

You'll have to make this conversion depending on the json parser/generator library you use.

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

You'll want to look into capturing in regex to handle wrapping the 3 in ^3.

Plain ol' javascript:

var input = document.getElementById('inputID');

input.onkeyup = function(){
    this.value = this.value.toUpperCase();
}

Javascript with jQuery:

$('#inputID').keyup(function(){
    this.value = this.value.toUpperCase();
});

It's not an insert if the record already exists in t1 (the user_id matches) unless you are happy to create duplicate user_id's.

You might want an update?

UPDATE t1
   SET <t1.col_list> = (SELECT <t2.col_list>
                          FROM t2
                         WHERE t2.user_id = t1.user_id)
 WHERE EXISTS
      (SELECT 1
         FROM t2
        WHERE t1.user_id = t2.user_id);

Hope it helps...

And also, use .prepend() to add the option to the start of the options list. http://api.jquery.com/prepend/

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

Apple's new system font is not publicly exposed. Apple has started abstracting system font names:

The motivation for this abstraction is so the operating system can make better choices on which face to use at a given weight. Apple is also working on font features, such as selectable “6" and “9" glyphs or non-monospaced numbers. It’s my guess that they’d like to bring these features to the web, as well.

Safari and Firefox use SF for -apple-system; Chrome recognizes BlinkMacSystemFont:

body {
    font-family: -apple-system, BlinkMacSystemFont, sans-serif;
}

There are also other variations:

font-family: -apple-system-body
font-family: -apple-system-headline
font-family: -apple-system-subheadline
font-family: -apple-system-caption1
font-family: -apple-system-caption2
font-family: -apple-system-footnote
font-family: -apple-system-short-body
font-family: -apple-system-short-headline
font-family: -apple-system-short-subheadline
font-family: -apple-system-short-caption1
font-family: -apple-system-short-footnote
font-family: -apple-system-tall-body

You can demo these at the following fiddle; most are not supported yet: http://jsfiddle.net/v94gw9nx/

I got my info from Craig Hockenberry's article which has a lot of great info about using the font: http://furbo.org/2015/07/09/i-left-my-system-fonts-in-san-francisco/

Also, some great info on the Surfin' Safari blog about using abstracted system fonts: https://www.webkit.org/blog/3709/using-the-system-font-in-web-content/

And apparently Apple is working with the W3C to standardize using a generic "system" font name in CSS. https://lists.w3.org/Archives/Public/www-style/2015Jul/0169.html

To close your current window using JS, do this. First open the current window to trick your current tab into thinking it has been opened by a script. Then close it using window.close(). The below script should go into the parent window, not the child window. You could run this after running the script to open the child.

<script type="text/javascript">
    window.open('','_parent',''); 
    window.close();
</script>

What types of files is not mentioned. If they're media files, go ahead with flat files. You probably just need a DB for tags and some way to associate the "external BLOBs" to the records in the DB. But if full text search is something you need, there's no other way to go but migrate to a full DB.

Another thing, your filesystem might provide the ceiling as far as number of physical files are concerned.

You should create a bound scope variable and watch its changes:

return {
   restrict: 'E',
   scope: {
     name: '='
   },
   link: function(scope) {
     scope.$watch('name', function() {
        // all the code here...
     });
   }
};

The correct method is to register your custom URL Protocol in windows registry as follows:

[HKEY_CLASSES_ROOT\customurl]
@="Description here"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\customurl\shell]

[HKEY_CLASSES_ROOT\customurl\shell\open]

[HKEY_CLASSES_ROOT\customurl\shell\open\command]
@="\"C:\\Path To Your EXE\\ExeName.exe\" \"%1\""

Once the above keys and values are added, from the web page, just call "customurl:\\parameter1=xxx&parameter2=xxx" . You will receive the entire url as the argument in exe, which you need to process inside your exe. Change 'customurl' with the text of your choice.

I believe your issue is with regards to the server. The angular documentation with regards to HTML5 mode (at the link in your question) states:

Server side Using this mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your application (e.g. index.html)

I believe you'll need to setup a url rewrite from /about to /.

in your server.py file make : host ='192.168.1.94' instead of host = socket.gethostname()

Allow me to share my approach for what it's worth. For me converting the commandfield to a templatefield control is not an option, as the commandfield comes with built-in functionality that I would otherwise have to create myself, for example the fact that it changes to "Update Cancel" when Edit is clicked, and that when Edit is clicked, all the cells in the row which are labels become textboxes, etc.

In my approach, you can leave the commandfield as is, then you can hide it as needed via code behind. In this example, I am hiding it if the field "Scenario" of the grid shows the text "Actual" for the relevant row of the RowDataBound event.

protected void gridDetail_RowDataBound(object sender, GridViewRowEventArgs e)
    {   
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (((Label)e.Row.FindControl("lblScenario")).Text == "Actual")
            {
                LinkButton cmdField= (LinkButton)e.Row.Cells[0].Controls[0];
                cmdField.Visible = false;
            }
    }}

Here is a version of @adabyron's answer that prevents the leaky EventArgs abstraction.

First, the modified EventToCommandBehavior class (now a generic abstract class and formatted with ReSharper code cleanup). Note the new GetCommandParameter virtual method and its default implementation:

public abstract class EventToCommandBehavior<TEventArgs> : Behavior<FrameworkElement>
    where TEventArgs : EventArgs
{
    public static readonly DependencyProperty EventProperty = DependencyProperty.Register("Event", typeof(string), typeof(EventToCommandBehavior<TEventArgs>), new PropertyMetadata(null, OnEventChanged));
    public static readonly DependencyProperty CommandProperty = DependencyProperty.Register("Command", typeof(ICommand), typeof(EventToCommandBehavior<TEventArgs>), new PropertyMetadata(null));
    public static readonly DependencyProperty PassArgumentsProperty = DependencyProperty.Register("PassArguments", typeof(bool), typeof(EventToCommandBehavior<TEventArgs>), new PropertyMetadata(false));
    private Delegate _handler;
    private EventInfo _oldEvent;

    public string Event
    {
        get { return (string)GetValue(EventProperty); }
        set { SetValue(EventProperty, value); }
    }

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    public bool PassArguments
    {
        get { return (bool)GetValue(PassArgumentsProperty); }
        set { SetValue(PassArgumentsProperty, value); }
    }

    protected override void OnAttached()
    {
        AttachHandler(Event);
    }

    protected virtual object GetCommandParameter(TEventArgs e)
    {
        return e;
    }

    private void AttachHandler(string eventName)
    {
        _oldEvent?.RemoveEventHandler(AssociatedObject, _handler);

        if (string.IsNullOrEmpty(eventName))
        {
            return;
        }

        EventInfo eventInfo = AssociatedObject.GetType().GetEvent(eventName);

        if (eventInfo != null)
        {
            MethodInfo methodInfo = typeof(EventToCommandBehavior<TEventArgs>).GetMethod("ExecuteCommand", BindingFlags.Instance | BindingFlags.NonPublic);

            _handler = Delegate.CreateDelegate(eventInfo.EventHandlerType, this, methodInfo);
            eventInfo.AddEventHandler(AssociatedObject, _handler);
            _oldEvent = eventInfo;
        }
        else
        {
            throw new ArgumentException($"The event '{eventName}' was not found on type '{AssociatedObject.GetType().FullName}'.");
        }
    }

    private static void OnEventChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var behavior = (EventToCommandBehavior<TEventArgs>)d;

        if (behavior.AssociatedObject != null)
        {
            behavior.AttachHandler((string)e.NewValue);
        }
    }

    // ReSharper disable once UnusedMember.Local
    // ReSharper disable once UnusedParameter.Local
    private void ExecuteCommand(object sender, TEventArgs e)
    {
        object parameter = PassArguments ? GetCommandParameter(e) : null;

        if (Command?.CanExecute(parameter) == true)
        {
            Command.Execute(parameter);
        }
    }
}

Next, an example derived class that hides DragCompletedEventArgs. Some people expressed concern about leaking the EventArgs abstraction into their view model assembly. To prevent this, I created an interface that represents the values we care about. The interface can live in the view model assembly with the private implementation in the UI assembly:

// UI assembly
public class DragCompletedBehavior : EventToCommandBehavior<DragCompletedEventArgs>
{
    protected override object GetCommandParameter(DragCompletedEventArgs e)
    {
        return new DragCompletedArgs(e);
    }

    private class DragCompletedArgs : IDragCompletedArgs
    {
        public DragCompletedArgs(DragCompletedEventArgs e)
        {
            Canceled = e.Canceled;
            HorizontalChange = e.HorizontalChange;
            VerticalChange = e.VerticalChange;
        }

        public bool Canceled { get; }
        public double HorizontalChange { get; }
        public double VerticalChange { get; }
    }
}

// View model assembly
public interface IDragCompletedArgs
{
    bool Canceled { get; }
    double HorizontalChange { get; }
    double VerticalChange { get; }
}

Cast the command parameter to IDragCompletedArgs, similar to @adabyron's answer.

old question, but posting this for fellow googlers:

Spin.js DOES WORK for this use case: http://fgnass.github.com/spin.js/

As this is a concern of presentation, a pure CSS solution would be ideal. However, this question was posed in 2012, and although relative positioning / negative margin solutions have been suggested, these approaches seem rather hacky, create potential flow issues, and cannot respond dynamically to changes in the DOM / viewport.

With that in mind I believe that using JavaScript is still (February 2017) the best approach. Below is a vanilla-JS solution which will respond both to anchor clicks and resolve the page hash on load (See JSFiddle). Modify the .getFixedOffset() method if dynamic calculations are required. If you're using jQuery, here's a modified solution with better event delegation and smooth scrolling.

(function(document, history, location) {
  var HISTORY_SUPPORT = !!(history && history.pushState);

  var anchorScrolls = {
    ANCHOR_REGEX: /^#[^ ]+$/,
    OFFSET_HEIGHT_PX: 50,

    /**
     * Establish events, and fix initial scroll position if a hash is provided.
     */
    init: function() {
      this.scrollToCurrent();
      window.addEventListener('hashchange', this.scrollToCurrent.bind(this));
      document.body.addEventListener('click', this.delegateAnchors.bind(this));
    },

    /**
     * Return the offset amount to deduct from the normal scroll position.
     * Modify as appropriate to allow for dynamic calculations
     */
    getFixedOffset: function() {
      return this.OFFSET_HEIGHT_PX;
    },

    /**
     * If the provided href is an anchor which resolves to an element on the
     * page, scroll to it.
     * @param  {String} href
     * @return {Boolean} - Was the href an anchor.
     */
    scrollIfAnchor: function(href, pushToHistory) {
      var match, rect, anchorOffset;

      if(!this.ANCHOR_REGEX.test(href)) {
        return false;
      }

      match = document.getElementById(href.slice(1));

      if(match) {
        rect = match.getBoundingClientRect();
        anchorOffset = window.pageYOffset + rect.top - this.getFixedOffset();
        window.scrollTo(window.pageXOffset, anchorOffset);

        // Add the state to history as-per normal anchor links
        if(HISTORY_SUPPORT && pushToHistory) {
          history.pushState({}, document.title, location.pathname + href);
        }
      }

      return !!match;
    },

    /**
     * Attempt to scroll to the current location's hash.
     */
    scrollToCurrent: function() {
      this.scrollIfAnchor(window.location.hash);
    },

    /**
     * If the click event's target was an anchor, fix the scroll position.
     */
    delegateAnchors: function(e) {
      var elem = e.target;

      if(
        elem.nodeName === 'A' &&
        this.scrollIfAnchor(elem.getAttribute('href'), true)
      ) {
        e.preventDefault();
      }
    }
  };

  window.addEventListener(
    'DOMContentLoaded', anchorScrolls.init.bind(anchorScrolls)
  );
})(window.document, window.history, window.location);

If you are using Python 3, you can use urllib.parse

url = """example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0"""

import urllib.parse
urllib.parse.unquote(url)

gives:

'example.com?title=????????+??????'

What is the length of str array, and with how much 0s it is ending?

Let's find out:

int main() {
  char str[] = "Hello\0";
  int length = sizeof str / sizeof str[0];
  // "sizeof array" is the bytes for the whole array (must use a real array, not
  // a pointer), divide by "sizeof array[0]" (sometimes sizeof *array is used)
  // to get the number of items in the array
  printf("array length: %d\n", length);
  printf("last 3 bytes: %02x %02x %02x\n",
         str[length - 3], str[length - 2], str[length - 1]);
  return 0;
}

If I am not late....

For Firefox, one can import the same har file from Network tab.

If you are in ES6 just use the "static" keyword on your method from your example would be the following: static alertMessage: function() { ...
},

Hope can help anyone out there :)

When you define varchar etc without a length, the default is 1.

When n is not specified in a data definition or variable declaration statement, the default length is 1. When n is not specified with the CAST function, the default length is 30.

So, if you expect 400 bytes in the @trackingItems1 column from stock, use nvarchar(400).

Otherwise, you are trying to fit >1 character into nvarchar(1) = fail

As a comment, this is bad use of table value function too because it is "multi statement". It can be written like this and it will run better

ALTER FUNCTION [dbo].[testing1](@price int)
RETURNS
AS
   SELECT ta.item, ta.warehouse, ta.price 
   FROM   stock ta
   WHERE  ta.price >= @price;

Of course, you could just use a normal SELECT statement..

Just use strcmp() for case sensitive and strcmpi() or stricmp() for case insensitive comparison. Which are both in the header file <string.h>

format:

int strcmp(const char*,const char*);    //for case sensitive
int strcmpi(const char*,const char*);   //for case insensitive

Usage:

string a="apple",b="ApPlE",c="ball";
if(strcmpi(a.c_str(),b.c_str())==0)      //(if it is a match it will return 0)
    cout<<a<<" and "<<b<<" are the same"<<"\n";
if(strcmpi(a.c_str(),b.c_str()<0)
    cout<<a[0]<<" comes before ball "<<b[0]<<", so "<<a<<" comes before "<<b;

Output

apple and ApPlE are the same

a comes before b, so apple comes before ball

In ES6, the includes() method is used to determine whether one string may be found within another string, returning true or false as appropriate.

var str = 'To be, or not to be, that is the question.';

console.log(str.includes('To be'));       // true
console.log(str.includes('question'));    // true
console.log(str.includes('nonexistent')); // false

Here is jsperf between

var ret = str.includes('one');

And

var ret = (str.indexOf('one') !== -1);

As the result shown in jsperf, it seems both of them perform well.

For Debian distributions. Nothing worked for until I added the debian main repositories on the apt sources (I don't know how were they removed): sudo vi /etc/apt/sources.list

and added

deb  http://deb.debian.org/debian  stretch main
deb-src  http://deb.debian.org/debian  stretch main

after that sudo apt-get update (you can upgrade too) and finally sudo apt-get install php-sqlite3

Another similar method to those described above is to use plt.ylim for example:

plt.ylim(max(y_array), min(y_array))

This method works for me when I'm attempting to compound multiple datasets on Y1 and/or Y2

Query to achieve your requirment

SELECT id,GROUP_CONCAT(text SEPARATOR ' ') AS text FROM table_name group by id;

For my system the problem ended up being that I still had Mysql 5.6 installed and so the mysql_upgrade.exe from that installation was being called instead of the one for 5.7. Navigate to C:\Program Files\MySQL\MySQL Server 5.7\bin and run .\mysql_upgrade.exe -u root

If your model is called BlogPost, it would be:

BlogPost.all.map(&:destroy)

Maybe is late now but following Spacedman, did you try duplicate="strip" or any other option?

x=runif(1000)
y=runif(1000)
z=rnorm(1000)
s=interp(x,y,z,duplicate="strip")
surface3d(s$x,s$y,s$z,color="blue")

There are many ways to do it with sed or awk:

sed -n '/TERMINATE/,$p' file

This looks for TERMINATE in your file and prints from that line up to the end of the file.

awk '/TERMINATE/,0' file

This is exactly the same behaviour as sed.

In case you know the number of the line from which you want to start printing, you can specify it together with NR (number of record, which eventually indicates the number of the line):

awk 'NR>=535' file

Example

$ seq 10 > a        #generate a file with one number per line, from 1 to 10
$ sed -n '/7/,$p' a
7
8
9
10
$ awk '/7/,0' a
7
8
9
10
$ awk 'NR>=7' a
7
8
9
10

It works with params if you capture an array with one element, that holds the current index.

int[] idx = { 0 };
params.forEach(e -> query.bind(idx[0]++, e));

The above code assumes, that the method forEach iterates through the elements in encounter order. The interface Iterable specifies this behaviour for all classes unless otherwise documented. Apparently it works for all implementations of Iterable from the standard library, and changing this behaviour in the future would break backward-compatibility.

If you are working with Streams instead of Collections/Iterables, you should use forEachOrdered, because forEach can be executed concurrently and the elements can occur in different order. The following code works for both sequential and parallel streams:

int[] idx = { 0 };
params.stream().forEachOrdered(e -> query.bind(idx[0]++, e));

Study up on multidimensional arrays. This question might help.

When jQuery is not present you get $ is undefined and not your message.

Did you check if you don't have a variable called $ somewhere before your code?
Inspect the value of $ in firebug to see what it is.

Slightly out of the question, but I can't resist to write a shorter code to your class assignment:

    var i = 1;
    $("ol li").each(function(){
        $(this).addClass('olli' + i++);
    });

Instance methods need to be called from an instance. Your setLoanItem method is an instance method (it doesn't have the modifier static), which it needs to be in order to function (because it is setting a value on the instance that it's called on (this)).

You need to create an instance of the class before you can call the method on it:

Media media = new Media();
media.setLoanItem("Yes");

(Btw it would be better to use a boolean instead of a string containing "Yes".)

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

(This was copied from this answer.)

In pydub we've recently opted to use ffplay (via subprocess) from the ffmpeg suite of tools, which internally uses SDL.

It works for our purposes – mainly just making it easier to test the results of pydub code in interactive mode – but it has it's downsides, like causing a new program to appear in the dock on mac.

I've linked the implementation above, but a simplified version follows:

import subprocess

def play(audio_file_path):
    subprocess.call(["ffplay", "-nodisp", "-autoexit", audio_file_path])

The -nodisp flag stops ffplay from showing a new window, and the -autoexit flag causes ffplay to exit and return a status code when the audio file is done playing.

edit: pydub now uses pyaudio for playback when it's installed and falls back to ffplay to avoid the downsides I mentioned. The link above shows that implementation as well.

You shouldn't loop till the square root of the number! It may be right some times, but not always!

Largest prime factor of 10 is 5, which is bigger than the sqrt(10) (3.16, aprox).

Largest prime factor of 33 is 11, which is bigger than the sqrt(33) (5.5,74, aprox).

You're confusing this with the propriety which states that, if a number has a prime factor bigger than its sqrt, it has to have at least another one other prime factor smaller than its sqrt. So, with you want to test if a number is prime, you only need to test till its sqrt.

You have misspelt the second pixels as pixel. The following works:

pixels = [1,2,3]
pixels[0] = 5

It appears that due to the typo you were trying to accidentally modify some tuple called pixel, and in Python tuples are immutable. Hence the confusing error message.

Lots of great answers here but they might be superseded by this CMake support in Visual Studio (Oct 5 2016)

Getting a stack trace of an unprepared python program, running in a stock python without debugging symbols can be done with pyrasite. Worked like a charm for me in on Ubuntu Trusty:

$ sudo pip install pyrasite
$ echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
$ sudo pyrasite 16262 dump_stacks.py # dumps stacks to stdout/stderr of the python program

(Hat tip to @Albert, whose answer contained a pointer to this, among other tools.)

You can install "psycopg" with the following command:

# sudo easy_install psycopg2

Alternatively, you can use pip :

# pip install psycopg2

easy_install and pip are included with ActivePython, or manually installed from the respective project sites.

Or, simply get the pre-built Windows installer.

Maybe you could make the field readonly and on submit disable all readonly fields

$(".myform").submit(function(e) {
  $("input[readonly]").prop("disabled", true);
});

and the input (+ script) should be

<input type="text" readonly="readonly" name="test" value="test" />

$('input[readonly]').click(function () {
  $(this).removeAttr('readonly');
});

A live example:

$(".myform").submit(function(e) {
  $("input[readonly]").prop("disabled", true);
  e.preventDefault();
});


$('.reset').click(function () {
  $("input[readonly]").prop("disabled", false);
})

$('input[readonly]').click(function () {
  $(this).removeAttr('readonly');
})

input[readonly] {
  color: gray;
  border-color: currentColor;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form class="myform">
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  <input readonly="readonly" value="test" />
  
  <button>Submit</button>
  <button class="reset" type="button">Reset</button>
</form>

You can use the code below:

document.body.addEventListener('click', function (evt) {
    if (evt.target.className === 'databox') {
        alert(this)
    }
}, false);

Well, you could, but you probably just want to have two sets of content in the same page, and switch between them. Example:

    <html>
    <head>
    <script>
    function show(shown, hidden) {
      document.getElementById(shown).style.display='block';
      document.getElementById(hidden).style.display='none';
      return false;
    }
    </script>
    </head>
    <body>
    
      <div id="Page1">
        Content of page 1
        <a href="#" onclick="return show('Page2','Page1');">Show page 2</a>
      </div>
    
      <div id="Page2" style="display:none">
        Content of page 2
        <a href="#" onclick="return show('Page1','Page2');">Show page 1</a>
      </div>
    
    </body>
    </html>

(Simplififed HTML code, should of course have doctype, etc.)

I'd like to add one suggestion I've used, based on defense in depth. You don't need to have the same auth&auth system for admins as regular users. You can have a separate login form on a separate url executing separate code for requests that will grant high privileges. This one can make choices that would be a total pain to regular users. One such that I've used is to actually scramble the login URL for admin access and email the admin the new URL. Stops any brute force attack right away as your new URL can be arbitrarily difficult (very long random string) but your admin user's only inconvenience is following a link in their email. The attacker no longer knows where to even POST to.

This code works fine:

import os


def readFile(filename):
    filehandle = open(filename)
    print filehandle.read()
    filehandle.close()



fileDir = os.path.dirname(os.path.realpath('__file__'))
print fileDir

#For accessing the file in the same folder
filename = "same.txt"
readFile(filename)

#For accessing the file in a folder contained in the current folder
filename = os.path.join(fileDir, 'Folder1.1/same.txt')
readFile(filename)

#For accessing the file in the parent folder of the current folder
filename = os.path.join(fileDir, '../same.txt')
readFile(filename)

#For accessing the file inside a sibling folder.
filename = os.path.join(fileDir, '../Folder2/same.txt')
filename = os.path.abspath(os.path.realpath(filename))
print filename
readFile(filename)

Use doc.childNodes to iterate through each span, and then filter the one whose className equals 4:

var doc = document.getElementById("test");
var notes = null;
for (var i = 0; i < doc.childNodes.length; i++) {
    if (doc.childNodes[i].className == "4") {
      notes = doc.childNodes[i];
      break;
    }        
}

Converting your value in milliseconds to days is simply (MsValue / 86,400,000)

We can get 1/1/1970 as numeric value by DATE(1970,1,1)

= (MsValueCellReference / 86400000) + DATE(1970,1,1)

Using your value of 1271664970687 and formatting it as dd/mm/yyyy hh:mm:ss gives me a date and time of 19/04/2010 08:16:11

This issue may also occur if you have multiple versions of the same support library android-support-v4.jar. If your project is using other library projects that contain different-2 versions of the support library. To resolve the issue keep the same version of support library at each place.

I've just had this issue, however it didn't occur straight away; after selecting a few cells they would stop calling didSelectItemAtIndexPath. I realised that the problem was the collection view had allowsMultipleSelection set to TRUE. Because cells were never getting deselected this stopped future calls from calling didSelectItemAtIndexPath.

If you have a worksheet with many rows that all contain the formula, by far the easiest method is to copy a row that is without data (but it does contain formulas), and then "insert copied cells" below/above the row where you want to add. The formulas remain. In a pinch, it is OK to use a row with data. Just clear it or overwrite it after pasting.

Mates,

I stumbled upon this error today while testing a simple script. I am not using "class" function though so it take it with grain of salt. I was calling function before its definition & declaration ...something like this

      try{
             foo();
         }
       catch (exception $e)
           {
            echo "$e->getMessage()";
           }

       function foo(){
                       echo "blah blah blah";
                     }

so php was throwing me error "call to undefined function ".

This kinda seem classic programming error but may help someone in need of clue.

Try an if statement ...

if @value is null 
    insert into t (value) values (default)
else
    insert into t (value) values (@value)

Use is_array function, when you will pass array to foreach loop.

if (is_array($your_variable)) {
  foreach ($your_variable as $item) {
   //your code
}
}

If you're using SQL Server 2005 or above, you can use the windowing function SUM() OVER ().

case 
when test1.TotalType = 'Average' then Test2.avgscore
when test1.TotalType = 'PercentOfTot' then (cnt/SUM(test1.qrank) over ())
else cnt
end as displayscore

But it'll be better if you show your full query to get context of what you actually need.

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

Do what the error message says:

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

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

• PostgreSQL isn't running

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

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

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

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

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

So ... check those:

• ps -f -u postgres should list postgres processes

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

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

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

This also works when $_SERVER['HTTPS'] is undefined

if( (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443 ){
    //enable secure connection
}

I have also faced same problem....

Actually this problem is raised due to the fact that your program .class files are not saved in that directory. Remove your CLASSPATH from your environment variable (you do no need to set classpath for simple Java programs) and reopen cmd prompt, then compile and execute.

If you observe carefully your .class file will save in the same location. (I am not an expert, I am also basic programer if there is any mistake in my sentences please ignore it :-))

Easy way to fill the missing values:-

filling string columns: when string columns have missing values and NaN values.

df['string column name'].fillna(df['string column name'].mode().values[0], inplace = True)

filling numeric columns: when the numeric columns have missing values and NaN values.

df['numeric column name'].fillna(df['numeric column name'].mean(), inplace = True)

filling NaN with zero:

df['column name'].fillna(0, inplace = True)

Try below code:

MessageBox.Show("Test Information Message", "Caption", MessageBoxButtons.OK, MessageBoxIcon.Information);

In order to use my example,Your file "abc.txt" needs to look like:

[your-config]
path1 = "D:\test1\first"
path2 = "D:\test2\second"
path3 = "D:\test2\third"

Then in your software you can use the config parser:

import ConfigParser

and then in you code:

 configParser = ConfigParser.RawConfigParser()   
 configFilePath = r'c:\abc.txt'
 configParser.read(configFilePath)

Use case:

self.path = configParser.get('your-config', 'path1')

*Edit (@human.js)

in python 3, ConfigParser is renamed to configparser (as described here)

Try this:

onclick="myfunction(
    '/myController/myAction',
    function(){myfuncionOnOK('/myController2/myAction2','myParameter2');},
    function(){myfuncionOnCancel('/myController3/myAction3','myParameter3');}
);"

Then you just need to call these two functions passed to myfunction:

function myfunction(url, f1, f2) {
    // …
    f1();
    f2();
}

Test its side-effects. This includes:

• Does it throw any exceptions? (If it should, check that it does. If it shouldn't, try some corner cases which might if you're not careful - null arguments being the most obvious thing.)
• Does it play nicely with its parameters? (If they're mutable, does it mutate them when it shouldn't and vice versa?)
• Does it have the right effect on the state of the object/type you're calling it on?

Of course, there's a limit to how much you can test. You generally can't test with every possible input, for example. Test pragmatically - enough to give you confidence that your code is designed appropriately and implemented correctly, and enough to act as supplemental documentation for what a caller might expect.

You can use date.js to achieve this:

var date = new Date('2014-01-06');
var newDate = date.toString('dd-MM-yy');

Alternatively, you can do it natively like this:

var dateAr = '2014-01-06'.split('-');_x000D_
var newDate = dateAr[1] + '-' + dateAr[2] + '-' + dateAr[0].slice(-2);_x000D_
_x000D_
console.log(newDate);

Try setting:

android:indeterminateDrawable="@drawable/progress" 

It worked for me. Here is also the code for progress.xml:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
    android:toDegrees="360">

    <shape android:shape="ring" android:innerRadiusRatio="3"
        android:thicknessRatio="8" android:useLevel="false">

        <size android:width="48dip" android:height="48dip" />

        <gradient android:type="sweep" android:useLevel="false"
            android:startColor="#4c737373" android:centerColor="#4c737373"
            android:centerY="0.50" android:endColor="#ffffd300" />

    </shape>

</rotate>

If the git bash is not working properly due to recently changed password.

You could open the Git GUI, and clone from there. It will ask for password, once entered, you can close the GIT GUI window.

Now the git bash will work perfectly.

Which line is throwing the exception? The new MemoryStream(...)? or the Image.FromStream(...)? And what is the byteArrayIn? Is it a byte[]? I only ask because of the comment "And none of value in it is not greater than 255" - which of course is automatic for a byte[].

As a more obvious question: does the binary actually contain an image in a sensible format?

For example, the following (although not great code) works fine:

    byte[] data = File.ReadAllBytes(@"d:\extn.png"); // not a good idea...
    MemoryStream ms = new MemoryStream(data);
    Image img = Image.FromStream(ms);
    Console.WriteLine(img.Width);
    Console.WriteLine(img.Height);

I got this error when I only updated the jquery library without updating the jqueryui library in parallel. I was using jquery 1.8.3 with jqueryui 1.9.0. However, when I updated jquery 1.8.3 to 1.9.1 I got the above error. When I commented out the offending .close method lines, it then threw an error about not finding .browser in the jquery library which was deprecated in jquery 1.8.3 and removed from jquery 1.9.1. So bascially, the jquery 1.9.1 library was not compatible with the jquery ui 1.9.0 library despite the jquery ui download page saying it works with jquery 1.6+. Essentially, there are unreported bugs when trying to use differing versions of the two. If you use the jquery version that comes bundled with the jqueryui download, I'm sure you'll be fine, but it's when you start using different versions that you off the beaten path and get errors like this. So, in summary, this error is from mis-matched versions (in my case anyway).

This program is doing almost everything with Public and private keys. The der format can be obtained but saving raw data ( without encoding base64). I hope this helps programmers.

For this and more use cases you can add flowing extension method to your library:

 public static List<DependencyObject> FindAllChildren(this DependencyObject dpo, Predicate<DependencyObject> predicate)
    {
        var results = new List<DependencyObject>();
        if (predicate == null)
            return results;


        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(dpo); i++)
        {
            var child = VisualTreeHelper.GetChild(dpo, i);
            if (predicate(child))
                results.Add(child);

            var subChildren = child.FindAllChildren(predicate);
            results.AddRange(subChildren);
        }
        return results;
    }

Example for your case:

 var children = dpObject.FindAllChildren(child => child is TextBox);

Reading the original comment, rutherford is looking for a cross-browser way to wrap unbroken text (inferred by his use of word-wrap for IE, designed to break unbroken strings).

/* Source: http://snipplr.com/view/10979/css-cross-browser-word-wrap */
.wordwrap { 
   white-space: pre-wrap;      /* CSS3 */   
   white-space: -moz-pre-wrap; /* Firefox */    
   white-space: -pre-wrap;     /* Opera <7 */   
   white-space: -o-pre-wrap;   /* Opera 7 */    
   word-wrap: break-word;      /* IE */
}

I've used this class for a bit now, and works like a charm. (note: I've only tested in FireFox and IE)

If you want just the summary of the exception use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

If you want to see the whole stack trace (usually better for debugging) use:

    try
    {
        test();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }

Another method I sometime use is:

    private DoSomthing(int arg1, int arg2, out string errorMessage)
    {
         int result ;
        errorMessage = String.Empty;
        try 
        {           
            //do stuff
            int result = 42;
        }
        catch (Exception ex)
        {

            errorMessage = ex.Message;//OR ex.ToString(); OR Free text OR an custom object
            result = -1;
        }
        return result;
    }

And In your form you will have something like:

    string ErrorMessage;
    int result = DoSomthing(1, 2, out ErrorMessage);
    if (!String.IsNullOrEmpty(ErrorMessage))
    {
        MessageBox.Show(ErrorMessage);
    }

If you could use Ant then you would just use the JUnitReport task as detailed here: http://ant.apache.org/manual/Tasks/junitreport.html, but you mentioned in your question that you're not supposed to use Ant. I believe that task merely transforms the XML report into HTML so it would be feasible to use any XSLT processor to generate a similar report.

Alternatively, you could switch to using TestNG ( http://testng.org/doc/index.html ) which is very similar to JUnit but has a default HTML report as well as several other cool features.

Update:

MongoServer.Create is obsolete now (thanks to @aknuds1). Instead this use following code:

var _server = new MongoClient(connectionString).GetServer();

It's easy. You should first take database name from connection string and then get database by name. Complete example:

var connectionString = "mongodb://localhost:27020/mydb";

//take database name from connection string
var _databaseName = MongoUrl.Create(connectionString).DatabaseName;
var _server = MongoServer.Create(connectionString);

//and then get database by database name:
_server.GetDatabase(_databaseName);

Important: If your database and auth database are different, you can add a authSource= query parameter to specify a different auth database. (thank you to @chrisdrobison)

From docs:

NOTE If you are using the database segment as the initial database to use, but the username and password specified are defined in a different database, you can use the authSource option to specify the database in which the credential is defined. For example, mongodb://user:pass@hostname/db1?authSource=userDb would authenticate the credential against the userDb database instead of db1.

The easiest way to implement this behaviour is by calling the pauseVideo and playVideo methods, when necessary. Inspired by the result of my previous answer, I have written a pluginless function to achieve the desired behaviour.

The only adjustments:

• I have added a function, toggleVideo
• I have added ?enablejsapi=1 to YouTube's URL, to enable the feature

Your change should work. However, there are potentially few php.ini configuration files with the 'xampp' stack. Try to identify whether or not there's an 'apache' specific php.ini. One potential location is:

C:\xampp\apache\bin\php.ini

uos??'s answer is fundamentally correct, but you probably don't want to do it in the mouseenter event. That's going to cause it to do the calculation to determine if it's needed, each time you mouse over the element. Unless the size of the element is changing, there's no reason to do that.

It would be better to just call this code immediately after the element is added to the DOM:

var $ele = $('#mightOverflow');
var ele = $ele.eq(0);
if (ele.offsetWidth < ele.scrollWidth)
    $ele.attr('title', $ele.text());

Or, if you don't know when exactly it's added, then call that code after the page is finished loading.

if you have more than a single element that you need to do this with, then you can give them all the same class (such as "mightOverflow"), and use this code to update them all:

$('.mightOverflow').each(function() {
    var $ele = $(this);
    if (this.offsetWidth < this.scrollWidth)
        $ele.attr('title', $ele.text());
});

You have two choices, either correct your markup so that it uses correct elements and utilizes the Bootstrap grid system:

@import url('http://getbootstrap.com/dist/css/bootstrap.css');

<div class="container">_x000D_
     <h1>About Me</h1>_x000D_
    <div class="row">_x000D_
        <div class="col-md-4">_x000D_
            <div class="imgAbt">_x000D_
                <img width="220" height="220" src="img/me.jpg" />_x000D_
            </div>_x000D_
        </div>_x000D_
        <div class="col-md-8">_x000D_
            <p>Lots of text here...With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and o</p>_x000D_
        </div>_x000D_
    </div>_x000D_
</div>

Or, if you wish the text to closely wrap the image, change your markup to:

@import url('http://getbootstrap.com/dist/css/bootstrap.css');

<div class="container">_x000D_
    <h1>About Me</h1>_x000D_
    <div class="row">_x000D_
        <div class="col-md-12">_x000D_
            <img style='float:left;width:200px;height:200px; margin-right:10px;' src="img/me.jpg" />_x000D_
            <p>Lots of text here...With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and o</p>_x000D_
        </div>_x000D_
    </div>

this would hep you

 DECLARE @DATE1 datetime = '2014-01-22 9:07:58.923'
 DECLARE @DATE2 datetime = '2014-01-22 10:20:58.923'
 SELECT DATEDIFF(HOUR, @DATE1,@DATE2) ,
        DATEDIFF(MINUTE, @DATE1,@DATE2) - (DATEDIFF(HOUR,@DATE1,@DATE2)*60)

 SELECT CAST(DATEDIFF(HOUR, @DATE1,@DATE2) AS nvarchar(200)) +
        ':'+ CAST(DATEDIFF(MINUTE, @DATE1,@DATE2)  -
                 (DATEDIFF(HOUR,@DATE1,@DATE2)*60) AS nvarchar(200))
As TotalHours

The original newbie approaches that I offered were (opt1):

$qb->where("e.fecha > '" . $monday->format('Y-m-d') . "'");
$qb->andWhere("e.fecha < '" . $sunday->format('Y-m-d') . "'");

And (opt2):

$qb->add('where', "e.fecha between '2012-01-01' and '2012-10-10'");

That was quick and easy and got the original poster going immediately.

Hence the accepted answer.

As per comments, it is the wrong answer, but it's an easy mistake to make, so I'm leaving it here as a "what not to do!"

Short answer: You can't.

CSS does not have techniques which affect the rendering of fonts in the browser; only the system can do that.

Obviously, text sharpness can easily be achieved with pixel-dense screens, but if you're using a normal PC that's gonna be hard to achieve.

There are some newer fonts that are smooth but at the sacrifice of it appearing somewhat blurry (look at most of Adobe's fonts, for example). You can also find some smooth-but-blurry-by-design fonts at Google Fonts, however.

There are some new CSS3 techniques for font rendering and text effects though the consistency, performance, and reliability of these techniques vary so largely to the point where you generally shouldn't rely on them too much.

Solution for a fresh install of Tomcat 7 on Ubuntu 12.04.

Edit this file - /etc/tomcat7/tomcat-users.xml to add this xml section -

<tomcat-users>
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="tomcatadmin" password="tomcat2009" roles="admin,admin-gui,manager-gui"/>
</tomcat-users>

restart Tomcat -

service tomcat7 restart

urls to access managers -

1. tomcat test page - http://localhost:8080/
2. manager webapp - http://localhost:8080/manager/html
3. host-manager webapp - http://localhost:8080/host-manager/html

just wanted to put the latest info out there.

The answer to many CSS formatting problems seems to be "add another <div>!"

So, in that spirit, have you tried adding a wrapper div to which the border/padding are applied and then putting the 100% width textarea inside of that? Something like (untested):

textarea_x000D_
{_x000D_
  width:100%;_x000D_
}_x000D_
.textwrapper_x000D_
{_x000D_
  border:1px solid #999999;_x000D_
  margin:5px 0;_x000D_
  padding:3px;_x000D_
}

<div style="display: block;" id="rulesformitem" class="formitem">_x000D_
  <label for="rules" id="ruleslabel">Rules:</label>_x000D_
  <div class="textwrapper"><textarea cols="2" rows="10" id="rules"/></div>_x000D_
</div>

In JavaScript, null is an object. There's another value for things that don't exist, undefined. The DOM returns null for almost all cases where it fails to find some structure in the document, but in JavaScript itself undefined is the value used.

Second, no, there is not a direct equivalent. If you really want to check for specifically for null, do:

if (yourvar === null) // Does not execute if yourvar is `undefined`

If you want to check if a variable exists, that can only be done with try/catch, since typeof will treat an undeclared variable and a variable declared with the value of undefined as equivalent.

But, to check if a variable is declared and is not undefined:

if (yourvar !== undefined) // Any scope

Previously, it was necessary to use the typeof operator to check for undefined safely, because it was possible to reassign undefined just like a variable. The old way looked like this:

if (typeof yourvar !== 'undefined') // Any scope

The issue of undefined being re-assignable was fixed in ECMAScript 5, which was released in 2009. You can now safely use === and !== to test for undefined without using typeof as undefined has been read-only for some time.

If you want to know if a member exists independent but don't care what its value is:

if ('membername' in object) // With inheritance
if (object.hasOwnProperty('membername')) // Without inheritance

If you want to to know whether a variable is truthy:

if (yourvar)

As far as I know, Both are same. For cross browser safety you can use window.location rather than document.location.

All modern browsers map document.location to window.location, but I still prefer window.location as that's what I've used since I wrote my first web page. it is more consistent.

you can also see document.location === window.location returns true, which clarifies that both are same.

you can also use flask_api for sending response

from flask_api import status

@app.route('/your-api/')
def empty_view(self):
    content = {'your content here'}
    return content, status.HTTP_201_CREATED

you can find reference here http://www.flaskapi.org/api-guide/status-codes/

In curl version 7.22.0 on Ubuntu and 7.24.0 on OSX the solution to not show progress but to show errors is to use both -s (--silent) and -S (--show-error) like so:

curl -sS http://google.com > temp.html

This works for both redirected output > /some/file, piped output | less and outputting directly to the terminal for me.

Update: Since curl 7.67.0 there is a new option --no-progress-meter which does precisely this and nothing else, see clonejo's answer for more details.

Try

import pandas as pd
pd.read_csv("../data_folder/data.csv")

Just for knowledge.. Also had the same issue and solved it stopping and starting again the mysql service... I think that was some conflict between mysql-service and tomcat.

Good Luck

You would need to add a property to your Production class and set it to point back at its parent, this doesn't exist by default.

To install a debug (test) apk, use -t:

Run Build-Make Project

Look for the last generated apk in the app folder.

Example:

adb  install -t C:\code\BackupRestore\app\build\outputs\apk\debug\app-debug.apk

An easier solution has been outlined here: Validate select box

Make the value be empty and add the required attribute

<select id="select" class="required">
<option value="">Choose an option</option> 
<option value="option1">Option1</option>
<option value="option2">Option2</option>
<option value="option3">Option3</option>
</select>

Run -> Run configurations, select project, second tab: “Arguments”. Top box is for your program, bottom box is for VM arguments, e.g. -Dkey=value.

Change this:

$(document).click( function () {

To this

$(document).on('click touchstart', function () {
