Private Sub YourWebPage_PreRenderComplete(sender As Object, e As EventArgs) Handles Me.PreRenderComplete

     If Not IsPostBack Then
     DropDownList1.Items.Insert(0, "Select")
     End If

End Sub

I think this is the culprit:

cmd = new SqlCommand(query, con);

DataTable dt = Select(query);

cmd.ExecuteNonQuery();

ddtype.DataSource = dt;

I don't know what that code is supposed to do, but it looks like you want to create an SqlDataReader for that, as explained here and all over the web if you search for "SqlCommand DropDownList DataSource":

cmd = new SqlCommand(query, con);
ddtype.DataSource = cmd.ExecuteReader();

Or you can create a DataTable as explained here:

cmd = new SqlCommand(query, con);

SqlDataAdapter listQueryAdapter = new SqlDataAdapter(cmd);
DataTable listTable = new DataTable();
listQueryAdapter.Fill(listTable);

ddtype.DataSource = listTable;

In simple way, Its not possible. Because DropdownList contain ListItem and it will be selected by default

But, you can use ValidationControl for that:

<asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID" Display="Dynamic" 
ValidationGroup="g1" runat="server" ControlToValidate="ControlID"
Text="*" ErrorMessage="ErrorMessage"></asp:RequiredFieldValidator>

Try this, it will insert the list item at index 0;

DropDownList1.Items.Insert(0, new ListItem("Add New", ""));

Please use the following

ddlCity.Items.Clear();

You have to use Kendo UI DropDownList select method (documentation in here).

Basically you should:

// get a reference to the dropdown list
var dropdownlist = $("#Instrument").data("kendoDropDownList");

If you know the index you can use:

// selects by index
dropdownlist.select(1);

If not, use:

// selects item if its text is equal to "test" using predicate function
dropdownlist.select(function(dataItem) {
    return dataItem.symbol === "test";
});

JSFiddle example here

lstDepartment.DataTextField = "DepartmentName";
lstDepartment.DataValueField = "DepartmentID";
lstDepartment.DataSource = dtDept;
lstDepartment.DataBind();
'Set the initial value:
lstDepartment.SelectedValue = depID;
lstDepartment.Attributes.Remove("InitialValue");
lstDepartment.Attributes.Add("InitialValue", depID);

And in your cancel method:

lstDepartment.SelectedValue = lstDepartment.Attributes("InitialValue");

And in your update method:

lstDepartment.Attributes("InitialValue") = lstDepartment.SelectedValue;

This error can also be caused by nested <form> tag in the master page which is not allowed.

<form id="someid"></form>

This will likely be the cause if you have picked up a template and copying the code from somewhere as it.

Solution

You have to break the nesting of <form> tag. The following should become

<form method="" name="form1">
  <form method="" name="form2>
  </form>
</form>

should become

<form method="" name="form1">    
</form>

<form method="" name="form2>    
</form>

You can do it programmatically:

ddlColor.DataSource = from p in db.ProductTypes
                                  where p.ProductID == pID
                                  orderby p.Color 
                                  select new { p.Color };
ddlColor.DataTextField = "Color";
ddlColor.DataBind();
ddlColor.Items.Insert(0, new ListItem("Select", "NA"));

Or add it in markup as:

<asp:DropDownList .. AppendDataBoundItems="true">
   <Items>
       <asp:ListItem Text="Select" Value="" />
   </Items>
</asp:DropDownList>

Depends on how you hid it.

If you used the CSS visibility value then

$('#test1').css('visibility', 'visible');

If you used CSS `display'

$('#test1').css('display', 'block'); //or inline or any of the other combos

You might even have made it opacity = 0

$('#test1').css('opacity', '1');

<asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID" Display="Dynamic" 
    ValidationGroup="g1" runat="server" ControlToValidate="ControlID"
    Text="*" ErrorMessage="ErrorMessage"></asp:RequiredFieldValidator>

protected void grvSecondaryLocations_RowEditing(object sender, GridViewEditEventArgs e)  
{  
    grvSecondaryLocations.EditIndex = e.NewEditIndex;  

    DropDownList ddlPbx = (DropDownList)(grvSecondaryLocations.Rows[grvSecondaryLocations.EditIndex].FindControl("ddlPBXTypeNS"));
    if (ddlPbx != null)  
    {  
        ddlPbx.DataSource = _pbxTypes;  
        ddlPbx.DataBind();  
    }  

    .... (more stuff)  
}

When a dictionary is enumerated, it will yield KeyValuePair<TKey,TValue> objects... so you just need to specify "Value" and "Key" for DataTextField and DataValueField respectively, to select the Value/Key properties.

Thanks to Joe's comment, I reread the question to get these the right way round. Normally I'd expect the "key" in the dictionary to be the text that's displayed, and the "value" to be the value fetched. Your sample code uses them the other way round though. Unless you really need them to be this way, you might want to consider writing your code as:

list.Add(cul.DisplayName, cod);

(And then changing the binding to use "Key" for DataTextField and "Value" for DataValueField, of course.)

In fact, I'd suggest that as it seems you really do want a list rather than a dictionary, you might want to reconsider using a dictionary in the first place. You could just use a List<KeyValuePair<string, string>>:

string[] languageCodsList = service.LanguagesAvailable();
var list = new List<KeyValuePair<string, string>>();

foreach (string cod in languageCodsList)
{
    CultureInfo cul = new CultureInfo(cod);
    list.Add(new KeyValuePair<string, string>(cul.DisplayName, cod));
}

Alternatively, use a list of plain CultureInfo values. LINQ makes this really easy:

var cultures = service.LanguagesAvailable()
                      .Select(language => new CultureInfo(language));
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

If you're not using LINQ, you can still use a normal foreach loop:

List<CultureInfo> cultures = new List<CultureInfo>();
foreach (string cod in service.LanguagesAvailable())
{
    cultures.Add(new CultureInfo(cod));
}
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

I can't see that you're adding these controls to the control hierarchy. Try:

Controls.Add ( ddlCountries );
Controls.Add ( ddlStates );

Events won't be invoked unless the control is part of the control hierarchy.

at last

ddlProducer.Items.Insert(0, "");

Well, like (almost) every console program for unix-like systems, git does not tell you anything if a command succeeds. It prints out something only if there's something wrong.

However if you want to be sure of what just happened, just type

git status

and see which changes are going to be committed and which not. I suggest you to use this before every commit, just to be sure that you are not forgetting anything.

Since you seem new to git, here is a link to a free online book that introduces you to git. It's very useful, it writes about basics as well as well known different workflows: http://git-scm.com/book

By specifying the option --user and --ask-password wget will ask for the credentials. Below is an example. Change the username and download link to your needs.

PuTTY's plink has a command-line argument for a password. Some other suggestions have been made in the answers to this question: using Expect (which is available for Windows), or writing a launcher in Python with Paramiko.

Same with something more complex...getting the ec2 instance region from within the instance.

INSTANCE_REGION=$(curl -s 'http://169.254.169.254/latest/dynamic/instance-identity/document' | python -c "import sys, json; print json.load(sys.stdin)['region']")

echo $INSTANCE_REGION

(sum of 1 to n) - (sum of all values in the array) = missing number

int sum = 0;
int idx = -1;
for (int i = 0; i < arr.length; i++) {
  if (arr[i] == 0) idx = i; else sum += arr[i];
}
System.out.println("missing number is: " + (5050 - sum) + " at index " + idx);

Very easy method, you rotate one way, and the contents the other. Requires a square though

#element{
    background : url('someImage.jpg');
}
#element:hover{
    transform: rotate(-30deg);
}
#element:hover >*{
    transform: rotate(30deg);
}

Apparently, the answer to the original poster's question is no. There is no standard C++ sgn function.

If you are able to copy the actual SQLite database file to your desktop, you can use this tools to browse the data.

You should make the Builder class as static and also you should make the fields final and have getters to get those values. Don't provide setters to those values. In this way your class will be perfectly immutable.

public class NutritionalFacts {
    private final int sodium;
    private final int fat;
    private final int carbo;

    public int getSodium(){
        return sodium;
    }

    public int getFat(){
        return fat;
    }

    public int getCarbo(){
        return carbo;
    }

    public static class Builder {
        private int sodium;
        private int fat;
        private int carbo;

        public Builder sodium(int s) {
            this.sodium = s;
            return this;
        }

        public Builder fat(int f) {
            this.fat = f;
            return this;
        }

        public Builder carbo(int c) {
            this.carbo = c;
            return this;
        }

        public NutritionalFacts build() {
            return new NutritionalFacts(this);
        }
    }

    private NutritionalFacts(Builder b) {
        this.sodium = b.sodium;
        this.fat = b.fat;
        this.carbo = b.carbo;
    }
}

And now you can set the properties as follows:

NutritionalFacts n = new NutritionalFacts.Builder().sodium(10).carbo(15).
fat(5).build();

This happened to me when a stored procedure running in SSMS encountered an error during the loop, while the cursor was in use to iterate over records and before the it was closed. To fix it I added extra code in the CATCH block to close the cursor if it is still open (using CURSOR_STATUS as other answers here suggest).

See this answer for a non JQuery solution. Just helped me out!

A small modification to answer from Alex is turning on and off of auto calculation.

open is a new access level in Swift 3, introduced with the implementation of

• SE-0117 Allow distinguishing between public access and public overridability

It is available with the Swift 3 snapshot from August 7, 2016, and with Xcode 8 beta 6.

In short:

• An open class is accessible and subclassable outside of the defining module. An open class member is accessible and overridable outside of the defining module.
• A public class is accessible but not subclassable outside of the defining module. A public class member is accessible but not overridable outside of the defining module.

So open is what public used to be in previous Swift releases and the access of public has been restricted. Or, as Chris Lattner puts it in SE-0177: Allow distinguishing between public access and public overridability:

“open” is now simply “more public than public”, providing a very simple and clean model.

In your example, open var hashValue is a property which is accessible and can be overridden in NSObject subclasses.

For more examples and details, have a look at SE-0117.

If you don't care at all do this:

    android:contentDescription="@null"

Although I would advise the accepted solutions, this is a hack :D

Installing framework 4.0 redistributable is also enough to create application pool. You can download it from here.

A lot of the answers given so far are pretty good, but you must clearly define what it is exactly that you want.

If you would like a alphabetical character followed by any number of non-white-space characters (note that it would also include numbers!) then you should use this:

^[A-Za-z]\S*$

If you would like to include only alpha-numeric characters and certain symbols, then use this:

^[A-Za-z][A-Za-z0-9!@#$%^&*]*$

Your original question looks like you are trying to include the space character as well, so you probably want something like this:

^[A-Za-z ][A-Za-z0-9!@#$%^&* ]*$

And that is my final answer!

I suggest taking some time to learn more about regular expressions. They are the greatest thing since sliced bread!

Try this syntax reference page (that site in general is very good).

ArgumentException:

ArgumentException is thrown when a method is invoked and at least one of the passed arguments does not meet the parameter specification of the called method. All instances of ArgumentException should carry a meaningful error message describing the invalid argument, as well as the expected range of values for the argument.

A few subclasses also exist for specific types of invalidity. The link has summaries of the subtypes and when they should apply.

To give another approach.

from flask import Flask, jsonify, request
app = Flask(__name__)

@app.route('/service', methods=['POST'])
def service():
    data = json.loads(request.data)
    text = data.get("text",None)
    if text is None:
        return jsonify({"message":"text not found"})
    else:
        return jsonify(data)

if __name__ == '__main__':
    app.run(host= '0.0.0.0',debug=True)

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

Screen Recording can be done in C# using VLC API. I have done a sample program to demonstrate this. It uses LibVLCSharp and VideoLAN.LibVLC.Windows libraries. You could achieve many more features related to video rendering using this cross platform API.

            }
        }
    }

** Update**: 11/19/2019

Microsoft has released a new version of the control 150.1400.0 in their Nuget library. My short testing shows that it works again in the forms designer where 150.1357.0 and 150.1358.0 did not. This includes being able to resize and modify the ReportViewer Tasks on the control itself.

** Update**: 8/18/2019

Removing the latest version and rolling back to 150.900.148.0 seems to work on multiple computers I'm using with VS2017 and VS2019.

You can roll back to 150.900.148 in the Nuget solution package manager. It works similarly to the previous versions. Use the drop down box to select the older version.

It may be easier to manually delete references to post 150.900 versions of ReportViewer and readd them than it is to fix them.

Remember to restart Visual Studio after changing the toolbox entry.

Update: 8/7/2019

A newer version of the ReportViewer control has been released, probably coinciding with Visual Studio 2019. I was working with V150.1358.0.

Following the directions in this answer gets the control in the designer's toolbox. But once dropped on the form it doesn't display. The control shows up below the form as a non-visual component.

This is working as designed according to Microsoft SQL BI support. This is the group responsible for the control.

While you still cannot interact with the control directly, these additional steps give a workaround so the control can be sized on the form. While now visible, the designer treats the control as if it didn't exist.

I've created a feedback request at the suggestion of Microsoft SQL BI support. Please consider voting on it to get Microsoft's attention.

Microsoft Azure Feedback page - Restore Designtime features of the WinForms ReportViewer Control

Additional steps:

• After adding the reportviewer to the WinForm
• Add a Panel Control to the WinForm.

• In the form's form.designer.cs file, add the Reportviewer control to the panel.

    // 
    // panel1
    // 
    this.panel1.Controls.Add(this.reportViewer1);
  

• Return to the form's designer, you should see the reportViewer on the panel

• In the Properties panel select the ReportViewer in the controls list dropdown
• Set the reportViewer's Dock property to Fill

Now you can position the reportViewer by actually interacting with the panel.

Update: Microsoft released a document on April 18, 2017 describing how to configure and use the reporting tool in Visual Studio 2017.

Visual Studio 2017 does not have the ReportViewer tool installed by default in the ToolBox. Installing the extension Microsoft Rdlc Report Designer for Visual Studio and then adding that to the ToolBox results in a non-visual component that appears below the form.

Microsoft Support had told me this is a bug, but as of April 21, 2017 it is "working as designed".

The following steps need to be followed for each project that requires ReportViewer.

• If you have ReportViewer in the Toolbox, remove it. Highlight, right-click and delete.
  • You will have to have a project with a form open to do this.

Edited 8/7/2019 - It looks like the current version of the RDLC Report Designer extension no longer interferes. You need this to actually edit the reports.

• If you have the Microsoft Rdlc Report Designer for Visual Studio extension installed, uninstall it.

• Close your solution and restart Visual Studio. This is a crucial step, errors will occur if VS is not restarted when switching between solutions.

• Open your solution.
• Open the NuGet Package Manager Console (Tools/NuGet Package Manager/Package Manager Console)

• At the PM> prompt enter this command, case matters.

  Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms

  You should see text describing the installation of the package.

Now we can temporarily add the ReportViewer tool to the tool box.

• Right-click in the toolbox and use Choose Items...

• We need to browse to the proper DLL that is located in the solutions Packages folder, so hit the browse button.

• In our example we can paste in the packages folder as shown in the text of Package Manager Console.

  C:\Users\jdoe\Documents\Projects\_Test\ReportViewerTest\WindowsFormsApp1\packages

• Then double click on the folder named Microsoft.ReportingServices.ReportViewerControl.Winforms.140.340.80

  The version number will probably change in the future.

• Then double-click on lib and again on net40.

• Finally, double click on the file Microsoft.ReportViewer.WinForms.dll

  You should see ReportViewer checked in the dialog. Scroll to the right and you will see the version 14.0.0.0 associated to it.

• Click OK.

ReportViewer is now located in the ToolBox.

• Drag the tool to the desired form(s).

• Once completed, delete the ReportViewer tool from the tool box. You can't use it with another project.

• You may save the project and are good to go.

Remember to restart Visual Studio any time you need to open a project with ReportViewer so that the DLL is loaded from the correct location. If you try and open a solution with a form with ReportViewer without restarting you will see errors indicating that the “The variable 'reportViewer1' is either undeclared or was never assigned.“.

If you add a new project to the same solution you need to create the project, save the solution, restart Visual Studio and then you should be able to add the ReportViewer to the form. I have seen it not work the first time and show up as a non-visual component.

When that happens, removing the component from the form, deleting the Microsoft.ReportViewer.* references from the project, saving and restarting usually works.

The 487 Response indicates that the previous request was terminated by user/application action. The most common occurrence is when the CANCEL happens as explained above. But it is also not limited to CANCEL. There are other cases where such responses can be relevant. So it depends on where you are seeing this behavior and whether its a user or application action that caused it.

15.1.2 UAS Behavior==> BYE Handling in RFC 3261

The UAS MUST still respond to any pending requests received for that dialog. It is RECOMMENDED that a 487 (Request Terminated) response be generated to those pending requests.

Go to your Target or Project settings, click the Gear icon at the bottom left, and select "Add User-Defined Setting". The new setting name should be GCC_PREPROCESSOR_DEFINITIONS, and you can type your definitions in the right-hand field.

Per Steph's comments, the full syntax is:

constant_1=VALUE constant_2=VALUE

Note that you don't need the '='s if you just want to #define a symbol, rather than giving it a value (for #ifdef statements)

After running following command:- mvn clean package install

I found the issue:
'dependencies.dependency.scope' for org.springframework.boot:spring-boot-starter-data-rest:pom must be one of [provided, compile, runtime, test, system] but is 'import'. @ line 13, column 11

One of the dependency was marked as 'import'. Changing the 'scope' solved the issue for me.

You can use the Median of Medians algorithm to find median of an unsorted array in linear time.

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.

Add relative positioning to the wrapping div tag, then absolutely position the image within it like this:

CSS:

.div-wrapper {
    position: relative;
    height: 300px;
    width: 300px;
}

.div-wrapper img {
    position: absolute;
    left: 0;
    bottom: 0;
}

HTML:

<div class="div-wrapper">
    <img src="blah.png"/>
</div>

Now the image sits at the bottom of the div.

Let's dissect it. There are three parts:

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

I honestly thought that the casting method would work fine. Since it doesn't you can try stringstream. An example is below:

#include <sstream>
#include <string>
std::stringstream ss;
std::string target;
char mychar = 'a';
ss << mychar;
ss >> target;

For that, you could use a Dictionary where the int is the key.

new Dictionary<int, string>();

If you really want to use a list, it could be a List<Tuple<int,string>>() but, Tuple class is readonly, so you have to recreate the instance to modifie it.

In my case, I had to load the Map on my Wordpress website and the problem was that the Google's api script was loading before the initMap(). Therefore, I solved the problem with a delay:

<script>
function initMap() {
     // Your Javascript Codes for the map
     ...
}

<?php
// Delay for 5 seconds
sleep(5);
?>

</script>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEYWY&callback=initMap"></script>

I needed to process the entire line as a whole. Here is what I found to work.

for /F "tokens=*" %%A in (myfile.txt) do [process] %%A

The tokens keyword with an asterisk (*) will pull all text for the entire line. If you don't put in the asterisk it will only pull the first word on the line. I assume it has to do with spaces.

For Command on TechNet

If there are spaces in your file path, you need to use usebackq. For example.

for /F "usebackq tokens=*" %%A in ("my file.txt") do [process] %%A

which is stored in the SharesPreferences as long as the application needs it.

Why?

As soon as the user wants to exit, the password in the SharedPreferences should be wiped and of course all activities of the application should be closed (it makes no sense to run them without the known password - they would crash).

Even better: don't put the password in SharedPreferences. Hold onto it in a static data member. The data will naturally go away when all activities in the app are exited (e.g., BACK button) or otherwise destroyed (e.g., kicked out of RAM to make room for other activities sometime after the user pressed HOME).

If you want some sort of proactive "flush password", just set the static data member to null, and have your activities check that member and take appropriate action when it is null.

i added some exception handling to @Aaron's answer.

import subprocess
import sys

try:
    import pandas as pd
except ImportError:
    subprocess.check_call([sys.executable, "-m", "pip", "install", 'pandas'])
finally:
    import pandas as pd

If you want your numbers in ascending order you can add them into a set and then sort the set into an ascending list.

s = set()
if number1 not in s:
  s.add(number1)
if number2 not in s:
  s.add(number2)
...
s = sorted(s)  #Now a list in ascending order

Just going to add a simple example to what everyone has explained,

json.load()

json.load can deserialize a file itself i.e. it accepts a file object, for example,

# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
  print(json.load(content))

will output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I use json.loads to open a file instead,

# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
  print(json.loads(content))

I would get this error:

TypeError: expected string or buffer

json.loads()

json.loads() deserialize string.

So in order to use json.loads I will have to pass the content of the file using read() function, for example,

using content.read() with json.loads() return content of the file,

with open("json_data.json", "r") as content:
  print(json.loads(content.read()))

Output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

That's because type of content.read() is string, i.e. <type 'str'>

If I use json.load() with content.read(), I will get error,

with open("json_data.json", "r") as content:
  print(json.load(content.read()))

Gives,

AttributeError: 'str' object has no attribute 'read'

So, now you know json.load deserialze file and json.loads deserialize a string.

Another example,

sys.stdin return file object, so if i do print(json.load(sys.stdin)), I will get actual json data,

cat json_data.json | ./test.py

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I want to use json.loads(), I would do print(json.loads(sys.stdin.read())) instead.

Based on the doc

<div class="row">
    <div class="span4 collapse-group">
        <h2>Heading</h2>
        <p class="collapse">Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
</div>

$('.row .btn').on('click', function(e) {
    e.preventDefault();
    var $this = $(this);
    var $collapse = $this.closest('.collapse-group').find('.collapse');
    $collapse.collapse('toggle');
});

Working demo.

Uffh. Don't you think this is the simplest solution?

    char inputChar = '|';
    int freq = "|fd|fdfd|f dfd|fd".replaceAll("[^" + inputChar +"]", "").length();
    System.out.println("freq " + freq);

Your PHP array is defined as:

$arr = array ('resonse'=>'error','comment'=>'test comment here');

Notice the mispelling "resonse". Also, as RaYell has mentioned, you have to use data instead of json in your success function because its parameter is currently data.

Try editing your PHP file to change the spelling form resonse to response. It should work then.

Try to use r.hasNext() instead of r.hasNextLine():

while(r.hasNext()) {
        scan = r.next();

if you are using PHP, you can set the value like this

<input type="date" value="<?php echo date("Y-m-d");?>">

but remember that it would return the date of the server. e.g. if your server in USA and your client in Indonesia, it may differ 1 day.

But if you want to use from the client, use javascript solution instead. hope it helps.

Unfortunately, there is no equivalent for Safari and the argument --disable-web-security doesn't work with Safari.

If you have access to the server side application, you can modify the https response headers to allow access. Mainly the Access-Control-Allow-Origin header. Modifying it will allow Safari to access the resource. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Access-Control-Allow-Origin for more information on the response headers that will help.

When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

For more : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

In another way,

If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”

There won't be any "merge commit" in fast-forwarding merge.

Carry Flag

The rules for turning on the carry flag in binary/integer math are two:

1. The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)

2. The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).

   • 0111 + 0001 = 1000 (carry flag is turned off [zero])
   • 1000 - 0001 = 0111 (carry flag is turned off [zero])

In unsigned arithmetic, watch the carry flag to detect errors.

In signed arithmetic, the carry flag tells you nothing interesting.

Overflow Flag

The rules for turning on the overflow flag in binary/integer math are two:

1. If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)

2. If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)

Otherwise the "overflow" flag is turned off

• 0100 + 0001 = 0101 (overflow flag is turned off)
• 0110 + 1001 = 1111 (overflow flag turned off)
• 1000 + 0001 = 1001 (overflow flag turned off)
• 1100 + 1100 = 1000 (overflow flag is turned off)

Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.

If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.

If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.

For more clarification please refer: http://teaching.idallen.com/dat2343/10f/notes/040_overflow.txt

Try giving these values:

 <corners android:topLeftRadius="6dp" android:topRightRadius="6dp"
         android:bottomLeftRadius="0.1dp" android:bottomRightRadius="0.1dp"/>

Note that I have changed 0dp to 0.1dp.

There is a way to make youtube autoplay, and complete playlists play through. Get Adblock browser for Android, and then go to the youtube website, and and configure it for the desktop version of the page, close Adblock browser out, and then reopen, and you will have the desktop version, where autoplay will work.

Using the desktop version will also mean that AdBlock will work. The mobile version invokes the standalone YouTube player, which is why you want the desktop version of the page, so that autoplay will work, and so ad blocking will work.

For a start the first select has 6 columns and the second has 4 columns. Perhaps make both have the same number of columns (adding nulls?).

I deleted the workbench.xmi in the folder workspace/.metadata/.plugins/org.eclipse.e4.workbench/.

I got this error because a build hung and then I tried to quit. However, I had unsaved changes. This prompted the following errors in logfile about unsaved changes and jobs that are not finished.

I have a similar scenario, and had no problem connecting after setting the JNLP port as you describe, and adding a single firewall rule allowing a connection on the server using that port. Granted it is a randomly selected client port going to a known server port (a host:ANY -> server:1 rule is needed).

From my reading of the source code, I don't see a way to set the local port to use when making the request from the slave. It's unfortunate, it would be a nice feature to have.

Alternatives:

Use a simple proxy on your client that listens on port N and then does forward all data to the actual Jenkins server on the remote host using a constant local port. Connect your slave to this local proxy instead of the real Jenkins server.

Create a custom Jenkins slave build that allows an option to specify the local port to use.

Remember also if you are using HTTPS via a self-signed certificate, you must alter the configuration jenkins-slave.xml file on the slave to specify the -noCertificateCheck option on the command line.

I had the same issue. The target frameworks were fine for me. Still it was not working. I installed VS2010 sp1, and did a "Rebuild" on the PrjTest. Then it started working for me.

What you are doing raises an exception (and rightfully so).

You can always do

try{
   window.a.b.c
}catch(e){
   console.log("YO",e)
}

But I wouldn't, instead think of your use case.

Why are you accessing data, 6 levels nested that you are unfamiliar of? What use case justifies this?

Usually, you'd like to actually validate what sort of object you're dealing with.

Also, on a side note you should not use statements like if(a.b) because it will return false if a.b is 0 or even if it is "0". Instead check if a.b !== undefined

Try setting the contentSize's height to the scrollView's height. Then the vertical scroll should be disabled because there would be nothing to scroll vertically.

scrollView.contentSize = CGSizeMake(scrollView.contentSize.width,scrollView.frame.size.height);

This is answering a slightly different question, but since I got stuck on this myself, I hope it might be useful for someone else.

If you want to use allow_redirects=False and get directly to the first redirect object, rather than following a chain of them, and you just want to get the redirect location directly out of the 302 response object, then r.url won't work. Instead, it's the "Location" header:

r = requests.get('http://github.com/', allow_redirects=False)
r.status_code  # 302
r.url  # http://github.com, not https.
r.headers['Location']  # https://github.com/ -- the redirect destination

More simple

sender side

Intent i = new Intent(SourceActiviti.this,TargetActivity.class);
i.putExtra("id","string data");
startActivity(i)

receiver side

Intent i = new Intent(SourceActiviti.this,TargetActivity.class);
String strData = i.getStringExtra("id");

macgyver offers face detection programs via a simple to use API.

The program below takes a reference to a public image and will return an array of the coordinates and dimensions of any faces detected in the image.

Insert can only operate on one table at a time. Multiple Inserts have to have multiple statements.

I don't know that you need to do the looping through a table variable - can't you just use a mass insert into one table, then the mass insert into the other?

By the way - I am guessing you mean copy the data from Object_Table; otherwise the question does not make sense.

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

You can simply do conditional check before doing map like

{Array.isArray(this.props.data.participants) && this.props.data.participants.map(function(player) {
   return <li key={player.championId}>{player.summonerName}</li>
   })
}

Now a days .map can be done in two different ways but still the conditional check is required like

.map with return

{Array.isArray(this.props.data.participants) && this.props.data.participants.map(player => {
   return <li key={player.championId}>{player.summonerName}</li>
 })
}

.map without return

{Array.isArray(this.props.data.participants) && this.props.data.participants.map(player => (
   return <li key={player.championId}>{player.summonerName}</li>
 ))
}

both the above functionalities does the same

Same pdo error in sql query while trying to insert into database value from multidimential array:

$sql = "UPDATE test SET field=arr[$s][a] WHERE id = $id";
$sth = $db->prepare($sql);    
$sth->execute();

Extracting array arr[$s][a] from sql query, using instead variable containing it fixes the problem.

Pass the data from Activity-1 to AndroidTabRes.. as below:

At sending activity...

Intent intent = new Intent(current.this, AndroidTabRestaurantDescSearchListView.class);
intent.putExtra("keyName","value");
startActivity(intent);

At AndroidTabRes.. activity...

  String data = getIntent().getExtras().getString("keyName");

Thus you can have data at receiving activity from sending activity...

And in your AndroidTabRestaurantDescSearchListView class, do this:

String value= getIntent().getStringExtra("keyName");

Intent intent = new Intent(this, RatingDescriptionSearchActivity.class);
intent.putExtra("keyName", value);
startActivity(intent);

Then in your RatingDescriptionSearchActivity class, do this:

 String data= getIntent().getStringExtra("keyName");

Something like this:

// Required field names
$required = array('login', 'password', 'confirm', 'name', 'phone', 'email');

// Loop over field names, make sure each one exists and is not empty
$error = false;
foreach($required as $field) {
  if (empty($_POST[$field])) {
    $error = true;
  }
}

if ($error) {
  echo "All fields are required.";
} else {
  echo "Proceed...";
}

The best way is to use layers insted of views:

AVPlayer *player = [AVPlayer playerWithURL:[NSURL url...]]; // 

AVPlayerLayer *layer = [AVPlayerLayer layer];

[layer setPlayer:player];
[layer setFrame:CGRectMake(10, 10, 300, 200)];
[layer setBackgroundColor:[UIColor redColor].CGColor];
[layer setVideoGravity:AVLayerVideoGravityResizeAspectFill];

[self.view.layer addSublayer:layer];

[player play];

Don't forget to add frameworks:

#import <QuartzCore/QuartzCore.h>
#import "AVFoundation/AVFoundation.h"

Use collectl which has extensive process I/O monitoring including monitoring threads.

Be warned that there are I/O counters for I/O being written to cache and I/O going to disk. collectl reports them separately. If you're not careful you can misinterpret the data. See http://collectl.sourceforge.net/Process.html

Of course, it shows a lot more than just process stats because you'd want one tool to provide everything rather than a bunch of different one that displays everything in different formats, right?

In the following example,

playground is the database name and equipment is the table name

Another way is using SHOW-COLUMNS:5.5 (available also for 5.5>)

$ mysql -uroot -p<password> -h<host> -P<port> -e \
    "SHOW COLUMNS FROM playground.equipment"

And the output:

mysql: [Warning] Using a password on the command line interface can be insecure.
+-------+-------------+------+-----+---------+----------------+
| Field | Type        | Null | Key | Default | Extra          |
+-------+-------------+------+-----+---------+----------------+
| id    | int(11)     | NO   | PRI | NULL    | auto_increment |
| type  | varchar(50) | YES  |     | NULL    |                |
| quant | int(11)     | YES  |     | NULL    |                |
| color | varchar(25) | YES  |     | NULL    |                |
+-------+-------------+------+-----+---------+----------------+

One can also use mysqlshow-client (also available for 5.5>) like following:

$ mysqlshow -uroot -p<password> -h<host> -P<port> \
    playground equipment

And the output:

mysqlshow: [Warning] Using a password on the command line interface can be insecure.

Depending on which environment you are using to run the emulator, check the logs to see how the emulator is started. Mine is started as:

C:\Users\johan\AppData\Local\Android\Sdk\tools\emulator.exe -netdelay none -netspeed full -avd Nexus_5X_API_23

Then you add the -http-proxy option, in my case:

C:\Users\johan\AppData\Local\Android\Sdk\tools\emulator.exe -netdelay none -netspeed full -avd Nexus_5X_API_23 -http-proxy 192.168.0.22:8888

You might consider using the :checked selector, provided by jQuery. Something like this:

$('.pChk').click(function() {
    if( $('.pChk:checked').length > 0 ) {
        $("#ProjectListButton").show();
    } else {
        $("#ProjectListButton").hide();
    }
}); 

Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET command. The first one to stop the service, the second one to start the service. Give them a STOP and START argument, followed by the service name.

In this example we restart the Printer Spooler service.

NET STOP "Print Spooler" 
NET START "Print Spooler"

Note: unfortunately NET RESTART <service name> does not exist.

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.

I had a slightly more specialised case, a search form which had an input which had autocomplete for a person name. The Javascript code set a hidden input which from.reset() does not clear.

However I didn't want to reset all hidden inputs. There I added a class, search-value, to the hidden inputs which where to be cleared.

$('form#search-form').reset();
$('form#search-form input[type=hidden].search-value').val('');

Oh my days!!

Feel so embarrassed but it is my first day on the C++.

I was getting the error because of two things.

1. I opened an empty project

2. I didn't add #include "stdafx.h"

It ran successfully on the win 32 console.

For those who may be confused by the accepted answer, as I was, you also need to have the ruby headers installed [ruby-devel].

The article that saved my hide is here.

And this is the revised solution (note that I'm on Fedora 13):

yum -y install gcc mysql-devel ruby-devel rubygems
gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config

For Debian, and other distributions using Debian style packaging the ruby development headers are installed by:

sudo apt-get install ruby-dev

For Ubuntu the ruby development headers are installed by:

sudo apt-get install ruby-all-dev

If you are using a earlier version of ruby (such as 2.2), then you will need to run:

sudo apt-get install ruby2.2-dev

(where 2.2 is your desired Ruby version)

This is a complete method that splits the string on any delimiter and returns a vector of the chopped up strings.

It is an adaptation from the answer from ryanbwork. However, his check for: if(token != mystring) gives wrong results if you have repeating elements in your string. This is my solution to that problem.

vector<string> Split(string mystring, string delimiter)
{
    vector<string> subStringList;
    string token;
    while (true)
    {
        size_t findfirst = mystring.find_first_of(delimiter);
        if (findfirst == string::npos) //find_first_of returns npos if it couldn't find the delimiter anymore
        {
            subStringList.push_back(mystring); //push back the final piece of mystring
            return subStringList;
        }
        token = mystring.substr(0, mystring.find_first_of(delimiter));
        mystring = mystring.substr(mystring.find_first_of(delimiter) + 1);
        subStringList.push_back(token);
    }
    return subStringList;
}

You can implement a custom serializer as follows:

public class Person {
    public String name;
    public int age;
    @JsonSerialize(using = IntToStringSerializer.class, as=String.class)
    public int favoriteNumber:
}


public class IntToStringSerializer extends JsonSerializer<Integer> {

    @Override
    public void serialize(Integer tmpInt, 
                          JsonGenerator jsonGenerator, 
                          SerializerProvider serializerProvider) 
                          throws IOException, JsonProcessingException {
        jsonGenerator.writeObject(tmpInt.toString());
    }
}

Java should handle the autoboxing from int to Integer for you.

String[] ops = str.split("\\s*[a-zA-Z]+\\s*");
String[] notops = str.split("\\s*[^a-zA-Z]+\\s*");
String[] res = new String[ops.length+notops.length-1];
for(int i=0; i<res.length; i++) res[i] = i%2==0 ? notops[i/2] : ops[i/2+1];

This should do it. Everything nicely stored in res.

Before you extract values from $_POST, you should check if they exist. You could use the isset function for this (http://php.net/manual/en/function.isset.php)

Run this through your query processor. It formats dates and/or times like so and one of these should give you what you're looking for. It wont be hard to adapt:

Declare @d datetime
select @d = getdate()

select @d as OriginalDate,
convert(varchar,@d,100) as ConvertedDate,
100 as FormatValue,
'mon dd yyyy hh:miAM (or PM)' as OutputFormat
union all
select @d,convert(varchar,@d,101),101,'mm/dd/yy'
union all
select @d,convert(varchar,@d,102),102,'yy.mm.dd'
union all
select @d,convert(varchar,@d,103),103,'dd/mm/yy'
union all
select @d,convert(varchar,@d,104),104,'dd.mm.yy'
union all
select @d,convert(varchar,@d,105),105,'dd-mm-yy'
union all
select @d,convert(varchar,@d,106),106,'dd mon yy'
union all
select @d,convert(varchar,@d,107),107,'Mon dd, yy'
union all
select @d,convert(varchar,@d,108),108,'hh:mm:ss'
union all
select @d,convert(varchar,@d,109),109,'mon dd yyyy hh:mi:ss:mmmAM (or PM)'
union all
select @d,convert(varchar,@d,110),110,'mm-dd-yy'
union all
select @d,convert(varchar,@d,111),111,'yy/mm/dd'
union all
select @d,convert(varchar,@d,12),12,'yymmdd'
union all
select @d,convert(varchar,@d,112),112,'yyyymmdd'
union all
select @d,convert(varchar,@d,113),113,'dd mon yyyy hh:mm:ss:mmm(24h)'
union all
select @d,convert(varchar,@d,114),114,'hh:mi:ss:mmm(24h)'
union all
select @d,convert(varchar,@d,120),120,'yyyy-mm-dd hh:mi:ss(24h)'
union all
select @d,convert(varchar,@d,121),121,'yyyy-mm-dd hh:mi:ss.mmm(24h)'
union all
select @d,convert(varchar,@d,126),126,'yyyy-mm-dd Thh:mm:ss:mmm(no spaces)'

Solution for those working with Huawei phones - You will get this error when ADB interface is not installed. Check if you have installed Huawei HiSuite. USB driver gets installed when you install HiSuite (I suppose this is true for most of the new phones that come with a Sync Software). If the ADB interface is installed on your computer you should see 'Android Composite ADB Interface' under Android Phone in your Device Manager as shown in this picture.

I ran across this question, and the one line of code I needed was hiding in big blocks of code.

Short answer: this.files[0].size

By the way, no JQuery needed.

OK! I'm really sorry to those that have actually submitted comments and answers, but I found the problem. I don't think this will help a lot of others trying to track down their personal SIGSEGV, but mine (and it was very hard) was entirely related to this:

https://code.google.com/p/android/issues/detail?id=8709

The libcrypto.so in my dump kind of clued me in. I do a MD5 hash of packet data when trying to determine if I've already seen the packet, and skipping it if I had. I thought at one point this was an ugly threading issue related to tracking those hashes, but it turned out it was the java.security.MessageDigest class! It's not thread safe!

I swapped it out with a UID I was stuffing in every packet based on the device UUID and a timestamp. No problems since.

I guess the lesson I can impart to those that were in my situation is, even if you're a 100% Java application, pay attention to the native library and symbol noted in the crash dump for clues. Googling for SIGSEGV + the lib .so name will go a lot farther than the useless code=1, etc... Next think about where your Java app could touch native code, even if it's nothing you're doing. I made the mistake of assuming it was a Service + UI threading issue where the Canvas was drawing something that was null, (the most common case I Googled on SIGSEGV) and ignored the possibility it could have been completely related to code I wrote that was related to the lib .so in the crash dump. Naturally java.security would use a native component in libcrypto.so for speed, so once I clued in, I Googled for Android + SIGSEGV + libcrypto.so and found the documented issue. Good luck!

Creating a 350 characters GUID:

dbms_random.STRING ('a', 350) - returning string in mixed case alpha characters

dbms_random.STRING ('x', 350) - returning string in uppercase alpha-numeric characters

I have used a syntax like this before:

$(ProjectDir)..\headers

or

..\headers

As other have pointed out, the starting directory is the one your project file is in(vcproj or vcxproj), not where your main code is located.

Angular 1.x

ng-route:

ng-route is developed by the angularJS Team for routing.

ng-route: url (Location) based routing.

Ex:

$routeProvider
    .when("/home", {
        templateUrl : "home.html"
    })

ui-route:

ui-router is develoepd by 3rd party module.

ui-router : state based routing

Ex:

 $stateProvider
        .state('home', {
            url: '/home',
            templateUrl: 'home.html'
        })

--> ui-router allows for nested views

--> ui-router more powerful than ng-route

ng-router, ui-router

In case you have both python 2 and 3 in your path, you can move up the Python27 folder in your path, so it search and executes python 2 first.

Shorter:

User.where("id > 200")

for anyone tunnelling with SSH; you can create a version of the gem command that uses SOCKS proxy:

1. Install socksify with gem install socksify (you'll need to be able to do this step without proxy, at least)

2. Copy your existing gem exe

   cp $(command which gem) /usr/local/bin/proxy_gem
   

3. Open it in your favourite editor and add this at the top (after the shebang)

   require 'socksify'
   
   if ENV['SOCKS_PROXY']
     require 'socksify'
     host, port = ENV['SOCKS_PROXY'].split(':')
     TCPSocket.socks_server = host || 'localhost'
     TCPSocket.socks_port = port.to_i || 1080
   end
   

4. Set up your tunnel

   ssh -D 8123 -f -C -q -N user@proxy
   

5. Run your gem command with proxy_gem

   SOCKS_PROXY=localhost:8123 proxy_gem push mygem
   

Just do

git pull origin [branch]

and then you should be able to push.

If you have commits on your own and didn't push it the branch yet, try

git pull --rebase origin [branch]

and then you should be able to push.

Read more about handling branches with Git.

Swift

Good solution to extend native functionality by extensions

import UIKit
    
extension UIImage {
  convenience init?(url: URL?) {
    guard let url = url else { return nil }
            
    do {
      self.init(data: try Data(contentsOf: url))
    } catch {
      print("Cannot load image from url: \(url) with error: \(error)")
      return nil
    }
  }
}

Usage

Convenience initializer is failable and accepts optional URL – approach is safe.

imageView.image = UIImage(url: URL(string: "some_url.png"))

There's MonoDevelop, which I occasionally use when I want to do some light C# coding when in Linux. It's nothing close to VS.Net, but it works for small projects. I really don't think most of the alternatives people have listed come anywhere close to VS.Net.

Use Console.ReadLine() at the end of the program. This will keep the window open until you press the Enter key. See https://docs.microsoft.com/en-us/dotnet/api/system.console.readline for details.

I realize this is an old thread, but i had the same problem since i moved to bluehost yesterday. It may not have been the selected answer but i support the bluehost article 206 reply.

I created a valid email in control panel and used it as my From address and it worked.

for more extendability for large scale apps use oop style with encapsulated fields.

Simple way :-

  class Fruit implements JsonSerializable {

        private $type = 'Apple', $lastEaten = null;

        public function __construct() {
            $this->lastEaten = new DateTime();
        }

        public function jsonSerialize() {
            return [
                'category' => $this->type,
                'EatenTime' => $this->lastEaten->format(DateTime::ISO8601)
            ];
        }
    }

echo json_encode(new Fruit()); //which outputs:

{"category":"Apple","EatenTime":"2013-01-31T11:17:07-0500"}

Real Gson on PHP :-

1. http://jmsyst.com/libs/serializer
2. http://symfony.com/doc/current/components/serializer.html
3. http://framework.zend.com/manual/current/en/modules/zend.serializer.html
4. http://fractal.thephpleague.com/ - serialize only

Additionally,

ggplot(dat, aes(x,y)) +
geom_point() +
scale_x_continuous(breaks = seq(min(dat$x), max(dat$x), by = 0.05))

Works for binned or discrete scaled x-axis data (I.e., rounding not necessary).

To make something like associative array in JavaScript you have to use objects. ?

var obj = {}; // {} will create an object
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);

I think This Error is Arrived Because of You are using Class Component in Respective React Platform that Doesn't get Proper Configuration. So You Write Configuration in componentWillMount().

componetWillMount() {
const config = {

because the downloaded .sql.tar file was somehow corrupted. Downloading and extracting it again solved the issue.

I like simbu's approach, but I ain't comfortable to use first-child or last-child. Instead I only modify the content of a repeating list-comma class.

.list-comma + .list-comma::before {

<span class="list-comma" ng-repeat="destination in destinations">
    {{destination.name}}

You should use Terms Query

{
    "query" : {
        "terms" : {
            "tags" : ["c", "d"]
        }
    }
}

From: https://fedoraproject.org/wiki/MinGW/Tutorial

As of Fedora 17 it is possible to easily build (cross-compile) binaries for the win32 and win64 targets. This is realized using the mingw-w64 toolchain: http://mingw-w64.sf.net/. Using this toolchain allows you to build binaries for the following programming languages: C, C++, Objective-C, Objective-C++ and Fortran.

"Tips and tricks for using the Windows cross-compiler": https://fedoraproject.org/wiki/MinGW/Tips

If we have parameter like below in our POM XML

<version>${project.version}.${svn.version}</version>
  <packaging>war</packaging>

I run maven command line as follows :

mvn clean install package -Dproject.version=10 -Dsvn.version=1

If you're not doing anything particularly professional you can always use a Util class. Ex, a util class from a project for a class.

public class Util {


public Util() {}
public boolean flip(boolean bool) { return !bool; }
public void sop(String str) { System.out.println(str); }

}

then just create a Util object Util u = new Util(); and have something for the return System.out.println( u.flip(bool) );

If you're gonna end up using the same thing over and over, use a method, and especially if it's across projects, make a Util class. Dunno what the industry standard is however. (Experienced programmers feel free to correct me)

You still need to set callback in the params:

var params = {
  'a': b,
  'token_auth': TOKEN,
  'callback': 'functionName'
};
$sce.trustAsResourceUrl(url);

$http.jsonp(url, {
  params: params
});

Where 'functionName' is a stringified reference to globally defined function. You can define it outside of your angular script and then redefine it in your module.

You could use the built-in module pprint (https://docs.python.org/3.9/library/pprint.html).

How you can read the file with json data and print it out.

import json
import pprint

json_data = None
with open('file_name.txt', 'r') as f:
    data = f.read()
    json_data = json.loads(data)

pprint.pprint(json_data)

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

You have to open and close your class with { ... } like:

public class mod_MyMod extends BaseMod
{
  public String Version()
  {
    return "1.2_02";
  }

  public void AddRecipes(CraftingManager recipes)
  {
     recipes.addRecipe(new ItemStack(Item.diamond), new Object[] {
        "#", Character.valueOf('#'), Block.dirt });
  }
}

#change-avatar-file is a file input #change-avatar-file is a img tag (the target of jcrop) The "key" is FR.onloadend Event https://developer.mozilla.org/en-US/docs/Web/API/FileReader

$('#change-avatar-file').change(function(){
        var currentImg;
        if ( this.files && this.files[0] ) {
            var FR= new FileReader();
            FR.onload = function(e) {
                $('#avatar-change-img').attr( "src", e.target.result );
                currentImg = e.target.result;
            };
            FR.readAsDataURL( this.files[0] );
            FR.onloadend = function(e){
                //console.log( $('#avatar-change-img').attr( "src"));
                var jcrop_api;

                $('#avatar-change-img').Jcrop({
                    bgFade:     true,
                    bgOpacity: .2,
                    setSelect: [ 60, 70, 540, 330 ]
                },function(){
                    jcrop_api = this;
                });
            }
        }
    });

Pass the ArrayList In argument.

    private static void order(ArrayList<Object> list) {

    Collections.sort(list, new Comparator() {

        public int compare(Object o2, Object o1) {

            String x1 =  o1.Date;
            String x2 =  o2.Date;

                return  x1.compareTo(x2);

        }
    });
}

add dependency for retrofit2

compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'

create class for base url

public class ApiClient     
{
public static final String BASE_URL = "base_url";

private static Retrofit retrofit = null;

public static Retrofit getClient() {
    if (retrofit==null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}

}

after that create class model to get value

public class ApprovalModel {

@SerializedName("key_parameter")
private String approvalName;
public String getApprovalName() {
    return approvalName;
}
}

create interface class

public interface ApiInterface { 
@GET("append_url")
Call<CompanyDetailsResponse> getCompanyDetails();
}

after that in main class

 if(Connectivity.isConnected(mContext)){
            final ProgressDialog mProgressDialog = new ProgressDialog(mContext);
            mProgressDialog.setIndeterminate(true);
            mProgressDialog.setMessage("Loading...");
            mProgressDialog.show();

            ApiInterface apiService =
                    ApiClient.getClient().create(ApiInterface.class);

            Call<CompanyDetailsResponse> call = apiService.getCompanyDetails();
            call.enqueue(new Callback<CompanyDetailsResponse>() {
                @Override
                public void onResponse(Call<CompanyDetailsResponse>call, Response<CompanyDetailsResponse> response) {
                    mProgressDialog.dismiss();
                    if(response!=null && response.isSuccessful()) {
                        List<CompanyDetails> companyList = response.body().getCompanyDetailsList();

                        if (companyList != null&&companyList.size()>0) {
                            for (int i = 0; i < companyList.size(); i++) {
                                Log.d(TAG, "" + companyList.get(i));
                            }
                         //get values
                        }else{
                            //show alert not get value
                        }
                    }else{
                        //show error message

                    }
                }

                @Override
                public void onFailure(Call<CompanyDetailsResponse>call, Throwable t) {
                    // Log error here since request failed
                    Log.e(TAG, t.toString());
                    mProgressDialog.dismiss();
                }
            });
        }else{
            //network error alert box

        }

This will make the div fixed at the bottom of the page but in case the page is long it will only be visible when you scroll down.

<style type="text/css">
  #footer {
    position : absolute;
    bottom : 0;
    height : 40px;
    margin-top : 40px;
  }
</style>
<div id="footer">I am footer</div>

The height and margin-top should be the same so that the footer doesnt show over the content.

There are two ways for case insensitive comparison:

1. Convert strings to upper case and then compare them using the strict operator (===). How strict operator treats operands read stuff at: http://www.thesstech.com/javascript/relational-logical-operators

2. Pattern matching using string methods:

   Use the "search" string method for case insensitive search. Read about search and other string methods at: http://www.thesstech.com/pattern-matching-using-string-methods

           var a = "apple";
           var b = "APPLE";  
           if (a.toUpperCase() === b.toUpperCase()) {

My specific case has the following scenario. Our tests

public class VenueResourceContainerTest extends BaseTixContainerTest

all extend

BaseTixContainerTest

and JUnit was trying to run BaseTixContainerTest. Poor BaseTixContainerTest was just trying to setup the container, setup the client, order some pizza and relax... man.

As mentioned previously, you can annotate the class with

@Ignore

But that caused JUnit to report that test as skipped (as opposed to completely ignored).

Tests run: 4, Failures: 0, Errors: 0, Skipped: 1

That kind of irritated me.

So I made BaseTixContainerTest abstract, and now JUnit truly ignores it.

Tests run: 3, Failures: 0, Errors: 0, Skipped: 0

Ctrl + . shows the menu. I find this easier to type than the alternative, Alt + Shift + F10.

This can be re-bound to something more familiar by going to Tools > Options > Environment > Keyboard > Visual C# > View.QuickActions

This error occurs when you push the data from your local directory to your remote git repository by following git command: git push -u origin master

As local directory and git remote directory's files conflicted.

Solution :

After committing all files to staging follow below steps.

1. Fetch the files from the remote repository as its conflict with the local working directory.

   • git pull <remoter-url> <branch-name>

2. Commit the changes again.

   • git add -A
   • git commit -m ‘<comment>'

3. After committed merge files with both directory you can use

   • git push -u origin master

This will fix the issue. Thanks.

BTW, in my case it was that I needed to specify the user/pwd in the url, not as independent properties, they were ignored and my OS user was used to connect

My config is in a WebSphere 8.5.5 server.xml file

<dataSource 
    jndiName="jdbc/tableauPostgreSQL" 
    type="javax.sql.ConnectionPoolDataSource">
    <jdbcDriver 
        javax.sql.ConnectionPoolDataSource="org.postgresql.ds.PGConnectionPoolDataSource" 
        javax.sql.DataSource="org.postgresql.ds.PGPoolingDataSource" 
        libraryRef="PostgreSqlJdbcLib"/>
    <properties 
        url="jdbc:postgresql://server:port/mydb?user=fred&amp;password=secret"/>
</dataSource>

This would not work and was getting the error:

<properties 
    user="fred"
    password="secret"
    url="jdbc:postgresql://server:port/mydb"/>

here is my solution (compiled CSS):

.row.row-xs-eq {
  display: table;
  table-layout: fixed;
  margin: 0;
}

.row.row-xs-eq::before {
  content: none;
}

.row.row-xs-eq::after {
  content: none;
}

.row.row-xs-eq > [class^='col-'] {
  display: table-cell;
  float: none;
  padding: 0;
}

@media (min-width: 768px) {
  .row.row-sm-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-sm-eq::before {
    content: none;
  }

  .row.row-sm-eq::after {
    content: none;
  }

  .row.row-sm-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

@media (min-width: 992px) {
  .row.row-md-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-md-eq::before {
    content: none;
  }

  .row.row-md-eq::after {
    content: none;
  }

  .row.row-md-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

@media (min-width: 1200px) {
  .row.row-lg-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-lg-eq::before {
    content: none;
  }

  .row.row-lg-eq::after {
    content: none;
  }

  .row.row-lg-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

So your code would look like:

<div class="row row-sm-eq">
  <!-- your old cols definition here -->
</div>

Basically this is the same system you use with .col-* classes with that difference you need to apply .row-* classes to the row itself.

With .row-sm-eq columns will be stacked on XS screens. If you don't need them to be stacked on any screens you can use .row-xs-eq.

The SASS version that we do actually use:

.row {
  @mixin row-eq-height {
    display: table;
    table-layout: fixed;
    margin: 0;

    &::before {
      content: none;
    }

    &::after {
      content: none;
    }

    > [class^='col-'] {
      display: table-cell;
      float: none;
      padding: 0;
    }
  }

  &.row-xs-eq {
    @include row-eq-height;
  }

  @media (min-width: $screen-sm-min) {
    &.row-sm-eq {
      @include row-eq-height;
    }
  }

  @media (min-width: $screen-md-min) {
    &.row-md-eq {
      @include row-eq-height;
    }
  }

  @media (min-width: $screen-lg-min) {
    &.row-lg-eq {
      @include row-eq-height;
    }
  }
}

Live demo

Note: mixing .col-xs-12 and .col-xs-6 inside a single row would not work properly.

...and the exact same arguments apply to this construct as well:

lock(typeof(SomeObject))

I have a very simple working example of geting pixel color from canvas.

First some basic HTML:

<canvas id="myCanvas" width="400" height="250" style="background:red;" onmouseover="echoColor(event)">
</canvas>

Then JS to draw something on the Canvas, and to get color:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.fillStyle = "black";
ctx.fillRect(10, 10, 50, 50);

function echoColor(e){
    var imgData = ctx.getImageData(e.pageX, e.pageX, 1, 1);
    red = imgData.data[0];
    green = imgData.data[1];
    blue = imgData.data[2];
    alpha = imgData.data[3];
    console.log(red + " " + green + " " + blue + " " + alpha);  
}

Here is a working example, just look at the console.

        $out[$index] = ( is_object ( $node ) ) ? xml2array ( $node ) : $node;

    return $out;
}

It could help you. However, if you convert XML to an array you will loose all attributes that might be present, so you cannot go back to XML and get the same XML.

Long time from last post but maybe it helps someone...

Shorted way than Paul H:

my_dic = session.query(query.all())
my_df = pandas.DataFrame.from_dict(my_dic)

You can follow this Google JavaScript Style Guide

In general, use functionNamesLikeThis, variableNamesLikeThis, ClassNamesLikeThis, EnumNamesLikeThis, methodNamesLikeThis, and SYMBOLIC_CONSTANTS_LIKE_THIS.

EDIT: See nice collection of JavaScript Style Guides And Beautifiers.

The long rest in between is due to your keyframe settings. Your current keyframe rules mean that the actual bounce happens only between 40% - 60% of the animation duration (that is, between 1s - 1.5s mark of the animation). Remove those rules and maybe even reduce the animation-duration to suit your needs.

Here is how your original keyframe settings would be interpreted by the browser:

• At 0% (that is, at 0s or start of animation) - translate by 0px in Y axis.
• At 20% (that is, at 0.5s of animation) - translate by 0px in Y axis.
• At 40% (that is, at 1s of animation) - translate by 0px in Y axis.
• At 50% (that is, at 1.25s of animation) - translate by 5px in Y axis. This results in a gradual upward movement.
• At 60% (that is, at 1.5s of animation) - translate by 0px in Y axis. This results in a gradual downward movement.
• At 80% (that is, at 2s of animation) - translate by 0px in Y axis.
• At 100% (that is, at 2.5s or end of animation) - translate by 0px in Y axis.

something like below

var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
    var friends= db.Friends.Where(f=>idList.Contains(f.ID)).ToList();
    friends.ForEach(a=>a.msgSentBy='1234');
    db.SaveChanges();
}

UPDATE:

you can update multiple fields as below

friends.ForEach(a =>
                      {
                         a.property1 = value1;
                         a.property2 = value2;
                      });

To my knowledge this is inherent to most widgets and the amount of "padding" differs among phone manufacturers. This padding is really white space between the image border and the image in the 9 patch image file.

For example on my Droid X, spinner widgets get extra white space than buttons, which makes it look awkward when you have a spinner inline with a button, yet on my wife's phone the same application doesn't have the same problem and looks great!

The only suggestion I would have is to create your own 9 patch files and use them in your application.

Ahhh the pains that are Android.

Edited: Clarify padding vs white space.

 SELECT * FROM users WHERE Id Between 15 and 25

it will print from 15 to 25 as like limit in MYSQl

I think it will help you.

from django.db import models
import ast

class ListField(models.TextField):
    __metaclass__ = models.SubfieldBase
    description = "Stores a python list"

    def __init__(self, *args, **kwargs):
        super(ListField, self).__init__(*args, **kwargs)

    def to_python(self, value):
        if not value:
            value = []

        if isinstance(value, list):
            return value

        return ast.literal_eval(value)

    def get_prep_value(self, value):
        if value is None:
            return value

        return unicode(value)

    def value_to_string(self, obj):
        value = self._get_val_from_obj(obj)
        return self.get_db_prep_value(value)

class ListModel(models.Model):
    test_list = ListField()

Example :

>>> ListModel.objects.create(test_list= [[1,2,3], [2,3,4,4]])

>>> ListModel.objects.get(id=1)

>>> o = ListModel.objects.get(id=1)
>>> o.id
1L
>>> o.test_list
[[1, 2, 3], [2, 3, 4, 4]]
>>> 

It would match any element p that's immediately adjacent to an element 'p'. See: http://www.w3.org/TR/CSS2/selector.html

Pure numpy

numpy.loadtxt(open("test.csv", "rb"), delimiter=",", skiprows=1)

Check out the loadtxt documentation.

You can also use python's csv module:

import csv
import numpy
reader = csv.reader(open("test.csv", "rb"), delimiter=",")
x = list(reader)
result = numpy.array(x).astype("float")

You will have to convert it to your favorite numeric type. I guess you can write the whole thing in one line:

result = numpy.array(list(csv.reader(open("test.csv", "rb"), delimiter=","))).astype("float")

Added Hint:

You could also use pandas.io.parsers.read_csv and get the associated numpy array which can be faster.

You can get the mouse positions by using this snippet:

function getMousePos(canvas, evt) {
    var rect = canvas.getBoundingClientRect();
    return {
        x: (evt.clientX - rect.left) / (rect.right - rect.left) * canvas.width,
        y: (evt.clientY - rect.top) / (rect.bottom - rect.top) * canvas.height
    };
}

This code takes into account both changing coordinates to canvas space (evt.clientX - rect.left) and scaling when canvas logical size differs from its style size (/ (rect.right - rect.left) * canvas.width see: Canvas width and height in HTML5).

Example: http://jsfiddle.net/sierawski/4xezb7nL/

You seem to be confusing asynchronous IO with asynchronous functions. node.js uses asynchronous non-blocking IO because non blocking IO is better. The best way to understand it is to go watch some videos by ryan dahl.

How do I write asynchronous functions for Node?

Just write normal functions, the only difference is that they are not executed immediately but passed around as callbacks.

How should I implement error event handling correctly

Generally API's give you a callback with an err as the first argument. For example

database.query('something', function(err, result) {
  if (err) handle(err);
  doSomething(result);
});

Is a common pattern.

Another common pattern is on('error'). For example

process.on('uncaughtException', function (err) {
  console.log('Caught exception: ' + err);
});

Edit:

var async_function = function(val, callback){
    process.nextTick(function(){
        callback(val);
    });
};

The above function when called as

async_function(42, function(val) {
  console.log(val)
});
console.log(43);

Will print 42 to the console asynchronously. In particular process.nextTick fires after the current eventloop callstack is empty. That call stack is empty after async_function and console.log(43) have run. So we print 43 followed by 42.

You should probably do some reading on the event loop.

You can try with mentioning "Accept: application/json" in your rest client header as well, if you are expecting your object as JSON in response.

If these worksheets reside in the same workbook, a simple solution would be to name the range, and have the formula refer to the named range. To name a range, select it, right click, and provide it with a meaningful name with Workbook scope.

For example =Sheet1!$A$1:$F$1 could be named: theNamedRange. Then your formula on Sheet2! could refer to it in your formula like this: =SUM(theNamedRange).

Incidentally, it is not clear from your question how you meant to use the range. If you put what you had in a formula (e.g., =SUM(Sheet1!A1:F1)) it will work, you simply need to insert that range argument in a formula. Excel does not resolve the range reference without a related formula because it does not know what you want to do with it.

Of the two methods, I find the named range convention is easier to work with.

It really depends on the sort of data you're bringing back. Since a DataSet is (in effect) just a collection of DataTable objects, you can return multiple distinct sets of data into a single, and therefore more manageable, object.

Performance-wise, you're more likely to get inefficiency from unoptimized queries than from the "wrong" choice of .NET construct. At least, that's been my experience.

I suggest that newbies connect a PL2303 to Ubuntu, chmod 777 /dev/ttyUSB0 (file-permissions) and connect to a CuteCom serial terminal. The CuteCom UI is simple \ intuitive. If the PL2303 is continuously broadcasting data, then Cutecom will display data in hex format

Find the default constraint with this query here:

SELECT
    df.name 'Constraint Name' ,
    t.name 'Table Name',
    c.NAME 'Column Name'
FROM sys.default_constraints df
INNER JOIN sys.tables t ON df.parent_object_id = t.object_id
INNER JOIN sys.columns c ON df.parent_object_id = c.object_id AND df.parent_column_id = c.column_id

This gives you the name of the default constraint, as well as the table and column name.

When you have that information you need to first drop the default constraint:

ALTER TABLE dbo.YourTable
DROP CONSTRAINT name-of-the-default-constraint-here

and then you can drop the column

ALTER TABLE dbo.YourTable DROP COLUMN YourColumn

Edited to add information about the File API

Since I originally wrote this answer, the File API has been proposed as a standard and implemented in most browsers (as of IE 10, which added support for FileReader API described here, though not yet the File API). The API is a bit more complicated than the older Mozilla API, as it is designed to support asynchronous reading of files, better support for binary files and decoding of different text encodings. There is some documentation available on the Mozilla Developer Network as well as various examples online. You would use it as follows:

var file = document.getElementById("fileForUpload").files[0];
if (file) {
    var reader = new FileReader();
    reader.readAsText(file, "UTF-8");
    reader.onload = function (evt) {
        document.getElementById("fileContents").innerHTML = evt.target.result;
    }
    reader.onerror = function (evt) {
        document.getElementById("fileContents").innerHTML = "error reading file";
    }
}

Original answer

There does not appear to be a way to do this in WebKit (thus, Safari and Chrome). The only keys that a File object has are fileName and fileSize. According to the commit message for the File and FileList support, these are inspired by Mozilla's File object, but they appear to support only a subset of the features.

If you would like to change this, you could always send a patch to the WebKit project. Another possibility would be to propose the Mozilla API for inclusion in HTML 5; the WHATWG mailing list is probably the best place to do that. If you do that, then it is much more likely that there will be a cross-browser way to do this, at least in a couple years time. Of course, submitting either a patch or a proposal for inclusion to HTML 5 does mean some work defending the idea, but the fact that Firefox already implements it gives you something to start with.

You have to patch catalina.jar, as this is version number the WTP adapter looks at. It's a quite useless check, and the adapter should allow you to start the server anyway, but nobody has though of that yet.

For years and with every version of Tomcat this is always a problem.

To patch you can do the following:

• cd [tomcat or tomee home]/lib
• mkdir catalina
• cd catalina/
• unzip ../catalina.jar
• vim org/apache/catalina/util/ServerInfo.properties

Make sure it looks like the following (the version numbers all need to start with 8.0):

server.info=Apache Tomcat/8.0.0
server.number=8.0.0
server.built=May 11 2016 21:49:07 UTC

Then:

• jar uf ../catalina.jar org/apache/catalina/util/ServerInfo.properties
• cd ..
• rm -rf catalina

Consider Apache Commons IO, it has a class called FileUtils that has a listFiles method that might be very useful in your case.

You can use the operating system's clear console method via system("");
for windows it would be system("cls"); for example
and instead of releasing three different codes for different operating systems. just make a method to get what os is running.
you can do this by detecting if unique system variables exist with #ifdef
e.g.

enum OPERATINGSYSTEM = {windows = 0, mac = 1, linux = 2 /*etc you get the point*/};

void getOs(){
    #ifdef _WIN32
        return OPERATINGSYSTEM.windows
    #elif __APPLE__ //etc you get the point

    #endif
}

int main(){
    int id = getOs();
    if(id == OPERATINGSYSTEM.windows){
        system("CLS");
    }else if (id == OPERATINGSYSTEM.mac){
        system("CLEAR");
    } //etc you get the point

}

There are multiple answers based on what you are doing with the string.

1) Using the string as an id (will not be modified). Passing it in by const reference is probably the best idea here: (std::string const&)

2) Modifying the string but not wanting the caller to see that change. Passing it in by value is preferable: (std::string)

3) Modifying the string but wanting the caller to see that change. Passing it in by reference is preferable: (std::string &)

4) Sending the string into the function and the caller of the function will never use the string again. Using move semantics might be an option (std::string &&)

Are you using an error handler? If you're ignoring errors and try to name a sheet the same as an existing sheet or a name with invalid characters, it could be just skipping over that line. See the CleanSheetName function here

http://www.dailydoseofexcel.com/archives/2005/01/04/naming-a-sheet-based-on-a-cell/

for a list of invalid characters that you may want to check for.

Update

Other things to try: Fully qualified references, throwing in a Doevents, code cleaning. This code qualifies your Sheets reference to ThisWorkbook (you can change it to ActiveWorkbook if that suits). It also adds a thousand DoEvents (stupid overkill, but if something's taking a while to get done, this will allow it to - you may only need one DoEvents if this actually fixes anything).

Dim WS As Worksheet
Dim i As Long

With ThisWorkbook
    Set WS = .Worksheets.Add(After:=.Sheets(.Sheets.Count))
End With

For i = 1 To 1000
    DoEvents
Next i

WS.Name = txtSheetName.Value

Finally, whenever I have a goofy VBA problem that just doesn't make sense, I use Rob Bovey's CodeCleaner. It's an add-in that exports all of your modules to text files then re-imports them. You can do it manually too. This process cleans out any corrupted p-code that's hanging around.

I've tried all but nothing worked in my case then I've changed these mentioned settings which resolved the issue quite well for me. Try If it could of any help latter viewers. These settings could be vary in your situation but make sure build all the including DLLs with the same config settings you kept initially (mentioned in the image.).

Cheers!

warning: LF will be replaced by CRLF.

Depending on the editor you are using, a text file with LF wouldn't necessary be saved with CRLF: recent editors can preserve eol style. But that git config setting insists on changing those...

Simply make sure that (as I recommend here):

git config --global core.autocrlf false

That way, you avoid any automatic transformation, and can still specify them through a .gitattributes file and core.eol directives.

windows git "LF will be replaced by CRLF"
Is this warning tail backward?

No: you are on Windows, and the git config help page does mention

Use this setting if you want to have CRLF line endings in your working directory even though the repository does not have normalized line endings.

As described in "git replacing LF with CRLF", it should only occur on checkout (not commit), with core.autocrlf=true.

       repo
    /        \ 
crlf->lf    lf->crlf 
 /              \    

As mentioned in XiaoPeng's answer, that warning is the same as:

warning: (If you check it out/or clone to another folder with your current core.autocrlf configuration,) LF will be replaced by CRLF
The file will have its original line endings in your (current) working directory.

As mentioned in git-for-windows/git issue 1242:

I still feel this message is confusing, the message could be extended to include a better explanation of the issue, for example: "LF will be replaced by CRLF in file.json after removing the file and checking it out again".

Note: Git 2.19 (Sept 2018), when using core.autocrlf, the bogus "LF will be replaced by CRLF" warning is now suppressed.

As quaylar rightly comments, if there is a conversion on commit, it is to LF only.

That specific warning "LF will be replaced by CRLF" comes from convert.c#check_safe_crlf():

if (checksafe == SAFE_CRLF_WARN)
  warning("LF will be replaced by CRLF in %s.
           The file will have its original line endings 
           in your working directory.", path);
else /* i.e. SAFE_CRLF_FAIL */
  die("LF would be replaced by CRLF in %s", path);

It is called by convert.c#crlf_to_git(), itself called by convert.c#convert_to_git(), itself called by convert.c#renormalize_buffer().

And that last renormalize_buffer() is only called by merge-recursive.c#blob_unchanged().

So I suspect this conversion happens on a git commit only if said commit is part of a merge process.

Note: with Git 2.17 (Q2 2018), a code cleanup adds some explanation.

See commit 8462ff4 (13 Jan 2018) by Torsten Bögershausen (tboegi).
^{(Merged by Junio C Hamano -- gitster -- in commit 9bc89b1, 13 Feb 2018)}

convert_to_git(): safe_crlf/checksafe becomes int conv_flags

When calling convert_to_git(), the checksafe parameter defined what should happen if the EOL conversion (CRLF --> LF --> CRLF) does not roundtrip cleanly.
In addition, it also defined if line endings should be renormalized (CRLF --> LF) or kept as they are.

checksafe was an safe_crlf enum with these values:

SAFE_CRLF_FALSE:       do nothing in case of EOL roundtrip errors
SAFE_CRLF_FAIL:        die in case of EOL roundtrip errors
SAFE_CRLF_WARN:        print a warning in case of EOL roundtrip errors
SAFE_CRLF_RENORMALIZE: change CRLF to LF
SAFE_CRLF_KEEP_CRLF:   keep all line endings as they are

Note that a regression introduced in 8462ff4 ("convert_to_git(): safe_crlf/checksafe becomes int conv_flags", 2018-01-13, Git 2.17.0) back in Git 2.17 cycle caused autocrlf rewrites to produce a warning message despite setting safecrlf=false.

Also you can try opensource WebRTC Media Server Kurento

Which can play RTSP video stream and send it to WebRTC or transcode to RTMP or saving on server.

We are useing it on Production for the following cases:

 - WebRTC to Webrtc (many to many)
 - WebRTC to RTMP
 - RTSP to WebRTC

Have a look at <openssl/pem.h>. It gives possible BEGIN markers.

Use the following syntax:

If you want to use printf, nothing prevents you from putting its result in a variable for further use:

$ foo=$(printf "%02d" 5)
$ echo "${foo}"

If you want to filter on a grandchild (or deeper) of the given object, you can continue to build out your object hierarchy. For example, if you want to filter on 'thing.properties.title', you can do the following:

<div ng-repeat="thing in things | filter: { properties: { title: title_filter } }">

You can also filter on multiple properties of an object just by adding them to your filter object:

<div ng-repeat="thing in things | filter: { properties: { title: title_filter, id: id_filter } }">

C# simple algorithm. (I'm posting it since I've tried to use the one you guys uploaded, but for some reason I couldn't compile it - extending a class? so I wrote my own one just in case someone else is facing the same problem I did). I'm not much into c# more than basic programming by the way, but this one works fine.

public static List<List<int>> GetSubsetsOfSizeK(List<int> lInputSet, int k)
        {
            List<List<int>> lSubsets = new List<List<int>>();
            GetSubsetsOfSizeK_rec(lInputSet, k, 0, new List<int>(), lSubsets);
            return lSubsets;
        }

public static void GetSubsetsOfSizeK_rec(List<int> lInputSet, int k, int i, List<int> lCurrSet, List<List<int>> lSubsets)
        {
            if (lCurrSet.Count == k)
            {
                lSubsets.Add(lCurrSet);
                return;
            }

            if (i >= lInputSet.Count)
                return;

            List<int> lWith = new List<int>(lCurrSet);
            List<int> lWithout = new List<int>(lCurrSet);
            lWith.Add(lInputSet[i++]);

            GetSubsetsOfSizeK_rec(lInputSet, k, i, lWith, lSubsets);
            GetSubsetsOfSizeK_rec(lInputSet, k, i, lWithout, lSubsets);
        }

USAGE: GetSubsetsOfSizeK(set of type List<int>, integer k)

You can modify it to iterate over whatever you are working with.

Good luck!

Here's a solution that moves the directives that need to be added dynamically, into the view and also adds some optional (basic) conditional-logic. This keeps the directive clean with no hard-coded logic.

The directive takes an array of objects, each object contains the name of the directive to be added and the value to pass to it (if any).

I was struggling to think of a use-case for a directive like this until I thought that it might be useful to add some conditional logic that only adds a directive based on some condition (though the answer below is still contrived). I added an optional if property that should contain a bool value, expression or function (e.g. defined in your controller) that determines if the directive should be added or not.

I'm also using attrs.$attr.dynamicDirectives to get the exact attribute declaration used to add the directive (e.g. data-dynamic-directive, dynamic-directive) without hard-coding string values to check for.

I'm trying to learn how to do this myself, and it seems you can install the library like this:

cmake_minimum_required(VERSION 2.4.0)

project(mycustomlib)

# Find source files
file(GLOB SOURCES src/*.cpp)

# Include header files
include_directories(include)

# Create shared library
add_library(${PROJECT_NAME} SHARED ${SOURCES})

# Install library
install(TARGETS ${PROJECT_NAME} DESTINATION lib/${PROJECT_NAME})

# Install library headers
file(GLOB HEADERS include/*.h)
install(FILES ${HEADERS} DESTINATION include/${PROJECT_NAME})

They're two different ways of representing data, but they're pretty dissimilar. The wikipedia pages for JSON and XML give some examples of each, and there's a comparison paragraph

In Firefox the onchange fires only when you tab or else click outside the input field. The same is true of Onblur. The difference is that onblur will fire whether you changed anything in the field or not. It is possible that ENTER will fire one or both of these, but you wouldn't know that if you disable the ENTER in your forms to prevent unexpected submits.

July 2012 - As this reply is rather old, but stills seems popular. I've written a blog post based on Apple's doco and placed it on my blog. I hope you guys find it useful.

Yes. In iPhone/iPad development the Default.png file is displayed by the device automatically so you don't have to program it which is really useful. I don't have it with me, but you need different PNGs for the iPad with specific names. I googled iPad default png and got this info from the phunkwerks site:

iPad Launch Image Orientations

To deal with various orientation options, a new naming convention has been created for iPad launch images. The screen size of the iPad is 768×1024, notice in the dimensions that follow the height takes into account a 20 pixel status bar.

Filename Dimensions

• Default-Portrait.png * — 768w x 1024h
• Default-PortraitUpsideDown.png — 768w x 1024h
• Default-Landscape.png ** — 1024w x 748h
• Default-LandscapeLeft.png — 1024w x 748h
• Default-LandscapeRight.png — 1024w x 748h
• iPad-Retina–Portrait.png — 1536w x 2048h
• iPad-Retina–Landscape.png — 2048w x 1496h
• Default.png — Not recommended

*—If you have not specified a Default-PortraitUpsideDown.png file, this file will take precedence.

**—If you have not specified a Default-LandscapeLeft.png or Default-LandscapeRight.png image file, this file will take precedence.

This link to "Apple's Developer Library" is useful, too.

You have to catch the error just as you're already doing for your save() call and since you're handling multiple errors here, you can try multiple calls sequentially in a single do-catch block, like so:

func deleteAccountDetail() {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()
    request.entity = entityDescription

    do {
        let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]

        for entity in fetchedEntities {
            self.Context!.deleteObject(entity)
        }

        try self.Context!.save()
    } catch {
        print(error)
    }
}

Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws then try to call the method. For example:

func deleteAccountDetail() throws {
    let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
    let request = NSFetchRequest()

    request.entity = entityDescription

    let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]

    for entity in fetchedEntities {
        self.Context!.deleteObject(entity)
    }

    try self.Context!.save()
}

With the new Substring type usage:

Swift 4:

var before: String = "Hello world!"
var lastCharIndex: Int = before.endIndex
var after:String = String(before[..<lastCharIndex])
print(after) // Hello world

Shorter way:

var before: String = "Hello world!"
after = String(before[..<before.endIndex])
print(after) // Hello world

I have tried the awnsers before but this did not work. Now I jsut used a LinearLayout instead of a TextureView, now it is working without any problem. Hope it helps some others who have the same problem. :)

    view = (LinearLayout) findViewById(R.id.view); //this is initialized in the constructor
    openWindowOnButtonClick();

public void openWindowOnButtonClick()
{
    view.setAlpha((float)0.5);
    FloatingActionButton fb = (FloatingActionButton) findViewById(R.id.floatingActionButton);
    final InputMethodManager keyboard = (InputMethodManager) getSystemService(getBaseContext().INPUT_METHOD_SERVICE);
    fb.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            // check if the Overlay should be visible. If this value is false, it is not shown -> show it.
            if(view.getVisibility() == View.INVISIBLE)
            {
                view.setVisibility(View.VISIBLE);
                keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
                Log.d("Overlay", "Klick");
            }
            else if(view.getVisibility() == View.VISIBLE)
            {
                view.setVisibility(View.INVISIBLE);
                keyboard.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
            }

In CMake you could use find_package to find libraries you need. There usually is a FindBoost.cmake along with your CMake installation.

As far as I remember, it will be installed to /usr/share/cmake/Modules/ along with other find-scripts for common libraries. You could just check the documentation in that file for more information about how it works.

An example out of my head:

FIND_PACKAGE( Boost 1.40 COMPONENTS program_options REQUIRED )
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )

ADD_EXECUTABLE( anyExecutable myMain.cpp )

TARGET_LINK_LIBRARIES( anyExecutable LINK_PUBLIC ${Boost_LIBRARIES} )

I hope this code helps.

• Here's the official documentation about FindBoost.cmake.
• And the actual FindBoost.cmake (hosted on GitHub)

TCPDF uses fopen() to save files. Any paths passed to TCPDF's Output() function should thus be an absolute path.

If you would like to save to a relative path, use e.g. the __DIR__ global constant (see this answer).

Before anyone spends to much time debugging this problem, most of the time it can be resolved by deleting node_modules and reinstalling the packages.

To Install:

If a lockfile exists you might use

yarn install --frozen-lockfile

or

npm ci

respectivly. if not then

yarn install

or

npm i

Think about it this way: you access static members via type name, like this:

MyStaticType.MyStaticMember();

Were you to inherit from that class, you would have to access it via the new type name:

MyNewType.MyStaticMember();

Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism.

Perhaps you're thinking you just want to extend some of the items in the original class. In that case, there's nothing preventing you from just using a member of the original in an entirely new type.

Perhaps you want to add methods to an existing static type. You can do that already via extension methods.

Perhaps you want to be able to pass a static Type to a function at runtime and call a method on that type, without knowing exactly what the method does. In that case, you can use an Interface.

So, in the end you don't really gain anything from inheriting static classes.

ES6 setTimeout

setTimeout(() => {
  console.log("we waited 204586560000 ms to run this code, oh boy wowwoowee!");
}, 204586560000);

Edit: 204586560000 ms is the approximate time between the original question and this answer... assuming I calculated correctly.

It is not something obvious, but the caret package has a function postResample() that will calculate "A vector of performance estimates" according to the documentation. The "performance estimates" are

• RMSE
• Rsquared
• mean absolute error (MAE)

and have to be accessed from the vector like this

library(caret)
vect1 <- c(1, 2, 3)
vect2 <- c(3, 2, 2)
res <- caret::postResample(vect1, vect2)
rsq <- res[2]

However, this is using the correlation squared approximation for r-squared as mentioned in another answer. I'm not sure why Max Kuhn didn't just use the conventional 1-SSE/SST.

caret also has an R2() method, although it's hard to find in the documentation.

The way to implement the normal coefficient of determination equation is:

preds <- c(1, 2, 3)
actual <- c(2, 2, 4)
rss <- sum((preds - actual) ^ 2)
tss <- sum((actual - mean(actual)) ^ 2)
rsq <- 1 - rss/tss

Not too bad to code by hand of course, but why isn't there a function for it in a language primarily made for statistics? I'm thinking I must be missing the implementation of R^2 somewhere, or no one cares enough about it to implement it. Most of the implementations, like this one, seem to be for generalized linear models.

If you need to call the same method from both Activities why not then use a third object?

public class FirstActivity extends Activity 
{  

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main2);

    }      

    // Utility.method() used somewhere in FirstActivity
}

public class Utility {

    public static void method()
    {

    }  

}

public class SecondActivity extends Activity 
{  

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main2);

        Utility.method();

    }
}

Of course making it static depends on the use case.

unicode('foo,bar').translate(dict([[ord(char), u''] for char in u',']))

Another option is to use JQuery to store the element's in-line style property, append to it, and to then update the element's style property with the new values. As follows:

function appendCSSToElement(element, CssProperties)
        {
            var existingCSS = $(element).attr("style");

             if(existingCSS == undefined) existingCSS = "";

            $.each(CssProperties, function(key,value)
            {
                existingCSS += " " + key + ": " + value + ";";
            });

            $(element).attr("style", existingCSS);

            return $(element);
        }

And then execute it with the new CSS attributes as an object.

appendCSSToElement("#ElementID", { "color": "white", "background-color": "green", "font-weight": "bold" });

This may not necessarily be the most efficient method (I'm open to suggestions on how to improve this. :) ), but it definitely works.

Fiddle

I've had a lot of success using thoonk.js along with thoonk.py. Thoonk leverages Redis (in-memory key-value store) to give you feed (think publish/subscribe), queue and job patterns for communication.

Why is this better than unix sockets or direct tcp sockets? Overall performance may be decreased a little, however Thoonk provides a really simple API that simplifies having to manually deal with a socket. Thoonk also helps make it really trivial to implement a distributed computing model that allows you to scale your python workers to increase performance, since you just spin up new instances of your python workers and connect them to the same redis server.

Data for last month-

select count(distinct switch_id)
  from [email protected]
 where dealer_name =  'XXXX'
   and to_char(CREATION_DATE,'MMYYYY') = to_char(add_months(trunc(sysdate),-1),'MMYYYY');

What worked for me was this lazy approach, not algorithmically lazy ;)

if( JSON.stringify(object_name).indexOf("key_name") > -1 ) {
    console.log("Key Found");
}
else{
    console.log("Key not Found");

AWS / Heroku are both free for small hobby projects (to start with).

If you want to start an app right away, without much customization of the architecture, then choose Heroku.

If you want to focus on the architecture and to be able to use different web servers, then choose AWS. AWS is more time-consuming based on what service/product you choose, but can be worth it. AWS also comes with many plugin services and products.

Heroku

• Platform as a Service (PAAS)
• Good documentation
• Has built-in tools and architecture.
• Limited control over architecture while designing the app.
• Deployment is taken care of (automatic via GitHub or manual via git commands or CLI).
• Not time consuming.

AWS

• Infrastructure as a Service (IAAS)
• Versatile - has many products such as EC2, LAMBDA, EMR, etc.
• Can use a Dedicated instance for more control over the architecture, such as choosing the OS, software version, etc. There is more than one backend layer.
• Elastic Beanstalk is a feature similar to Heroku's PAAS.
• Can use the automated deployment, or roll your own.

Java programming provides wrapper class for each primitive data types, to convert a primitive data types to correspond object of wrapper class.

Use document.querySelector() if you want to avoid frameworks (which I almost always want to do).

document.querySelector('input[name="gender"]:checked').value

You cannot add string literals like that in C. You have to create a buffer of size of string literal one + string literal two + a byte for null termination character and copy the corresponding literals to that buffer and also make sure that it is null terminated. Or you can use library functions like strcat.

In my opinion a For loop should be used when a fixed amount of iterations will be done and they won't be stopped before every iteration has been completed. In the other case where you want to quit earlier I prefer to use a While loop. Even if you read those two little words it seems more logical. Some examples:

for (int i=0;i<10;i++) {
    System.out.println(i);
}

When I read this code quickly I will know for sure it will print out 10 lines and then go on.

for (int i=0;i<10;i++) {
    if (someCondition) break;
    System.out.println(i);
}

This one is already less clear to me. Why would you first state you will take 10 iterations, but then inside the loop add some extra conditions to stop sooner?

I prefer the previous example written in this way (even when it's a little more verbose, but that's only with 1 line more):

int i=0;
while (i<10 && !someCondition) {
    System.out.println(i);
    i++;
}

Everyone who will read this code will see immediatly that there is an extra condition that might terminate the loop earlier.

Ofcourse in very small loops you can always discuss that every programmer will notice the break statement. But I can tell from my own experience that in larger loops those breaks can be overseen. (And that brings us to another topic to start splitting up code in smaller chunks)

The substitute of fcntl on windows are win32api calls. The usage is completely different. It is not some switch you can just flip.

In other words, porting a fcntl-heavy-user module to windows is not trivial. It requires you to analyze what exactly each fcntl call does and then find the equivalent win32api code, if any.

There's also the possibility that some code using fcntl has no windows equivalent, which would require you to change the module api and maybe the structure/paradigm of the program using the module you're porting.

If you provide more details about the fcntl calls people can find windows equivalents.

Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.

In project -> Add Component -> Windows Form and select a form

Add some label and buttons.

Initialize the value in constructor and call it from anywhere.

public class form1:System.Windows.Forms.Form
{
    public form1()
    {
    }

    public form1(string message,string buttonText1,string buttonText2)
    {
       lblMessage.Text = message;
       button1.Text = buttonText1;
       button2.Text = buttonText2;
    }
}

// Write code for button1 and button2 's click event in order to call 
// from any where in your current project.

// Calling

Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();

The Homebrew package manager includes launchctl plists to start automatically. For more information, run brew info postgres.

Start manually

pg_ctl -D /usr/local/var/postgres start

Stop manually

pg_ctl -D /usr/local/var/postgres stop

Start automatically

"To have launchd start postgresql now and restart at login:"

brew services start postgresql

What is the result of pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start?

What is the result of pg_ctl -D /usr/local/var/postgres status?

Are there any error messages in the server.log?

Make sure tcp localhost connections are enabled in pg_hba.conf:

# IPv4 local connections:
host    all    all    127.0.0.1/32    trust

Check the listen_addresses and port in postgresql.conf:

egrep 'listen|port' /usr/local/var/postgres/postgresql.conf

#listen_addresses = 'localhost'        # What IP address(es) to listen on;
#port = 5432                # (change requires restart)

Cleaning up

PostgreSQL was most likely installed via Homebrew, Fink, MacPorts or the EnterpriseDB installer.

Check the output of the following commands to determine which package manager it was installed with:

brew && brew list|grep postgres
fink && fink list|grep postgres
port && port installed|grep postgres

There once existed a plugin called JSEclipse that Adobe has subsequently sucked up and killed by making it available only by purchasing and installing FlexBuilder 3 (please someone prove me wrong). I found it to worked excellent but have since lost it since "upgrading" from Eclipse 3.4 to 3.4.1.

The feature I liked most was Content Outline.

In the Outline window of your Eclipse Screen, JSEclipse lists all classes in the currently opened file. It provides an overview of the class hierarchy and also method and property names. The outline makes heavy use of the code completion engine to find out more about how the code is structured. By clicking on the function entry in the list the cursor will be taken to the function declaration helping you navigate faster in long files with lots of class and method definitions

Using Virtual Attributes (Link to revised(paid) Railscast) you can store your price_in_cents in an integer column and add a virtual attribute price_in_dollars in your product model as a getter and setter.

# Add a price_in_cents integer column
$ rails g migration add_price_in_cents_to_products price_in_cents:integer

# Use virtual attributes in your Product model
# app/models/product.rb

def price_in_dollars
  price_in_cents.to_d/100 if price_in_cents
end

def price_in_dollars=(dollars)
  self.price_in_cents = dollars.to_d*100 if dollars.present?
end

Source: RailsCasts #016: Virtual Attributes: Virtual attributes are a clean way to add form fields that do not map directly to the database. Here I show how to handle validations, associations, and more.

With that solution the only scrollbar in the page is on your contents section in the middle! In that section build your structure with a sidebar or whatever you want!

You can do that with that code here:

<div class="navTop">
<h1>Title</h1>
    <nav>Dynamic menu</nav>
</div>
<div class="container">
    <section>THE CONTENTS GOES HERE</section>
</div>
<footer class="bottomFooter">
    Footer
</footer>

With that css:

.navTop{
width:100%;
border:1px solid black;
float:left;
}
.container{
width:100%;
float:left;
overflow:scroll;
}
.bottomFooter{
float:left;
border:1px solid black;
width:100%;
}

And a bit of jquery:

$(document).ready(function() {
  function setHeight() {
    var top = $('.navTop').outerHeight();
    var bottom = $('footer').outerHeight();
    var totHeight = $(window).height();
    $('section').css({ 
      'height': totHeight - top - bottom + 'px'
    });
  }

  $(window).on('resize', function() { setHeight(); });
  setHeight();
});

You can try this new library. JellyGif respects Gif frame duration while being highly CPU & Memory performant. It works great with UITableViewCell & UICollectionViewCell too. To get started you just need to

import JellyGif

let imageView = JellyGifImageView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))

//Animates Gif from the main bundle
imageView.startGif(with: .name("Gif name"))

//Animates Gif with a local path
let url = URL(string: "Gif path")!
imageView.startGif(with: .localPath(url))

//Animates Gif with data
imageView.startGif(with: .data(Data))

For more information you can look at its README

Shortest regexp I know (16 char)

^\d\d?[,.]\d\d?$

The ^ and $ means begin and end of input string (without this part 23.45 of string like 123.45 will be matched). The \d means digit, the \d? means optional digit, the [,.] means dot or comma. Working example (when you click on left menu> tools> code generator you can gen code for one of 9 popular languages like c#, js, php, java, ...) here.

// TEST
[
  // valid
  '11,11',   
  '11.11',
  '1.1',
  '1,1',
  // nonvalid
  '111,1',
  '11.111',
  '11-11',
  ',11',
  '11.',
  'a.11',
  '11,a',

  let result = /^\d\d?[,.]\d\d?$/.test(n);
  console.log(`${n}`.padStart(6,' '), 'is valid:', result);
})

That worked for me, change your web.config.

1. Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler, which defines a method that is invoked when a proxy method is invoked.

2. You create them by using the call

   Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
   

   The arguments are:

   1. classLoader. Once the class is generated, it is loaded with this class loader.
   2. interfaces. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.
   3. invocationHandler. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler. When a method from any of the supported interfaces, or hashCode, equals, or toString, is invoked, the method invoke is invoked on the handler, passing the Method object for the method to be invoked and the arguments passed.

   For more on this, see the documentation for the Proxy class.

3. Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.

There is a mistake in your insert statement chage it to below and try : String sql = "insert into table_name values ('" + Col1 +"','" + Col2 + "','" + Col3 + "')";

var val =$("#inputname").val();
$("#inputname").removeAttr('value').attr('value', val).focus();
// I think this is beter for all browsers...

I deleted the obj folder and then the project loaded as expected.

In the current version (v0.5.0-pre) the port seems to be available as a property on the server object, see http://nodejs.org/docs/v0.4.7/api/net.html#server.address

var server = http.createServer(function(req, res) {
    ...
}

server.listen(8088);
console.log(server.address());
console.log(server.address().address);
console.log(server.address().port);

outputs

{ address: '0.0.0.0', port: 8088 }
0.0.0.0

I faced the problem in IntelliJ Idea 14 actually. My project was working fine on Android Studio. I decided to continue development on IntelliJ idea. After import of project, I wasn't successful to RUN it and I got similar error message in Edit Configuration box. Based on What @Ali said, I deleted all my SDKs and reinstalled them again but didn't work.

I opened "Project Structure">"Platform Settings">SDKs. I found "Build target" of "Android API 21 Platform" is not set. By set it to one of my latest SDK the problem fixed and I could run project without problem.

1. Never insert data somewhere (especially not at beginning, like str = pad + str;), since the data will be reallocated everytime. Append always at end!
2. Don't pad your string in the loop. Leave it alone and build your pad string first. In the end concatenate it with your main string.
3. Don't assign padding string each time (like str += pad;). It is much faster to append the padding string to itself and extract first x-chars (the parser can do this efficiently if you extract from first char). This is exponential growth, which means that it wastes some memory temporarily (you should not do this with extremely huge texts).
