Today I ran into the exact same problem while working on a progressive web app (PWA) page and deleting some cache and service worker data for that page from Firefox. The dev console reported that none of the 4 Javascript files on the page would load anymore. The problem persisted in Safe mode, so it was not an add-on issue. The same script files loaded fine from other web pages on the same website. No amount of clearing the Firefox cache or wiping web page data from Firefox would help, nor would rebooting the Windows 10 PC. Chrome all the time worked fine on the problem page. In the end I did a restore of the entire Firefox profile folder from a day-old backup, and the problem was immediately gone, so it was not a problem with my PWA app. Apparently something in Firefox got corrupted.

It may happen, e.g. after an interrupted download, that Maven cached a broken version of the referenced package in your local repository.

Solution: Manually delete the folder of this plugin from cache (i.e. your local repository), and repeat maven install.

How to find the right folder? Folders in Maven repository follow the structure:

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-source-plugin</artifactId>
    <version>2.4</version>
</dependency>

is cached in ${USER_HOME}\.m2\repository\org\apache\maven\plugins\maven-source-plugin\2.4

With .Net 4.x you can use Task-based Asynchronous Pattern (TAP) to achieve this:

// .NET 4.x async-await
using UnityEngine;
using System.Threading.Tasks;
public class AsyncAwaitExample : MonoBehaviour
{
     private async void Start()
     {
        Debug.Log("Wait.");
        await WaitOneSecondAsync();
        DoMoreStuff(); // Will not execute until WaitOneSecond has completed
     }
    private async Task WaitOneSecondAsync()
    {
        await Task.Delay(TimeSpan.FromSeconds(1));
        Debug.Log("Finished waiting.");
    }
}

this is a feature to use .Net 4.x with Unity please see this link for description about it

and this link for sample project and compare it with coroutine

But becareful as documentation says that This is not fully replacement with coroutine

For UBUNTU 15.04,15.10,16.04 LTS, Debian 8 & Debian 9 Try this command:

sudo apt-get install lib32stdc++6

Just an addendum:

OnFragmentInteractionListener handle communication between Activity and Fragment using an interface (OnFragmentInteractionListener) and is created by default by Android Studio, but if you dont need to communicate with your activity, you can just get ride of it.

The goal is that you can attach your fragment to multiple activities and still reuse the same communication approach (Every activity could have its own OnFragmentInteractionListener for each fragment).

But and if im sure my fragment will be attached to only one type of activity and i want to communicate with that activity?

Then, if you dont want to use OnFragmentInteractionListener because of its verbosity, you can access your activity methods using:

((MyActivityClass) getActivity()).someMethod()

The recommendations from this article Extracting Data From Excel with SSIS resolved the issue for me.

I downloaded MS Access Database Engine 2010 32 bit driver from the link in that article.

Also set Project Configuration Properties for Debugging Run64BitRuntime = False

In SQL Server 2014 SSMS (Integration Service Catalog -> SSISDB -> Environments -> Projects for all Packages in Validate checked box 32 bit Runtime.

My SSIS packages are working now in both VS 2013 and SQL Server 2014 environments.

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

Under "Project -> Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions" add _CRT_SECURE_NO_WARNINGS

The following works with Visual Studio 2017 Community Edition on Windows 10 using SQLServer Express 2016.

Open a PowerShell check what it is called using SqlLocalDB.exe info and whether it is Running with SqlLocalDB.exe info NAME. Here's what it looks like on my machine:

> SqlLocalDB.exe info
MSSQLLocalDB
> SqlLocalDB.exe info MSSQLLocalDB
Name:               mssqllocaldb
Version:            13.0.1601.5
Shared name:
Owner:              DESKTOP-I4H3E09\simon
Auto-create:        Yes
State:              Running
Last start time:    4/12/2017 8:24:36 AM
Instance pipe name: np:\\.\pipe\LOCALDB#EFC58609\tsql\query
>

If it isn't running then you need to start it with SqlLocalDB.exe start MSSQLLocalDB. When it is running you see the Instance pipe name: which starts with np:\\. Copy that named pipe string. Within VS2017 open the view Server Explorer and create a new connection of type Microsoft SQL Server (SqlClient) (don't be fooled by the other file types you want the full fat connection type) and set the Server name: to be the instance pipe name you copied from PowerShell.

I also set the Connect to database to be the same database that was in the connection string that was working in my Dotnet Core / Entity Framework Core project which was set up using dotnet ef database update.

You can login and create a database using the sqlcmd and the named pipe string:

sqlcmd -S np:\\.\pipe\LOCALDB#EFC58609\tsql\query 1> create database EFGetStarted.ConsoleApp.NewDb; 2> GO

There are instructions on how to create a user for your application at https://docs.microsoft.com/en-us/sql/tools/sqllocaldb-utility

Try this may will help you.Go to "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.

You can copy-paste data from en excel-sheet to an SQL-table by doing so:

• Select the data in Excel and press Ctrl + C
• In SQL Server Management Studio right click the table and choose Edit Top 200 Rows
• Scroll to the bottom and select the entire empty row by clicking on the row header
• Paste the data by pressing Ctrl + V

Note: Often tables have a first column which is an ID-column with an auto generated/incremented ID. When you paste your data it will start inserting the leftmost selected column in Excel into the leftmost column in SSMS thus inserting data into the ID-column. To avoid that keep an empty column at the leftmost part of your selection in order to skip that column in SSMS. That will result in SSMS inserting the default data which is the auto generated ID.

Furthermore you can skip other columns by having empty columns at the same ordinal positions in the Excel sheet selection as those columns to be skipped. That will make SSMS insert the default value (or NULL where no default value is specified).

Follow this steps:

-Build
-Generate Signed Apk
-Create new

Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

Depending on the device, sometimes you are getting "The folder you specified doesn't contain a compatible software" error because the first interface isn't actually the ADB interface.

Try installing it as a generic "USB composite device" instead (from the 'pick from a list' driver install option); once the standard composite driver installs it will allow Windows to communicate with the device and detect the associated ADB driver interface and install it properly.

Self-referencing as example

public class Employee {
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public int ManagerId { get; set; }
    public virtual Employee Manager { get; set; }

    public virtual ICollection<Employee> Employees { get; set; }

    public Employee() {
        Employees = new HashSet<Employee>();
    }
}

HasMany(e => e.Employees)
    .WithRequired(e => e.Manager)
    .HasForeignKey(e => e.ManagerId)
    .WillCascadeOnDelete(false);

Execute following command:

set PATH="C:\Program Files (x86)\Java\jre7"

(whichever JRE exists in case of 64bit).

Because your Java Path is not set so you can just do this at command line and then execute the keytool import command.

git revert makes a new commit

git revert simply creates a new commit that is the opposite of an existing commit.

It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:

$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
 1 file changed, 1 insertion(+)
 create mode 100644 README.md
$ echo "bad update" > README.md 
$ git commit -am "bad update"
[master a1b9870] bad update
 1 file changed, 1 insertion(+), 1 deletion(-)

In this example the commit history has two commits and the last one is a mistake. Using git revert:

$ git revert HEAD
[master 1db4eeb] Revert "bad update"
 1 file changed, 1 insertion(+), 1 deletion(-)

There will be 3 commits in the log:

$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit

So there is a consistent history of what has happened, yet the files are as if the bad update never occured:

cat README.md 
Initial text

It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).

Closing questions

do you have to do something else after?

A git revert is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.

Do you have to commit the changes revert made or does revert directly commit to the repo?

git revert is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.

Obviously you'll need to push again and probably announce to the team.

Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).

The Advanced Editor did not resolve my issue, instead I was forced to edit dtsx-file through notepad (or your favorite text/xml editor) and manually replace values in attributes to

length="0" dataType="nText" (I'm using unicode)

Always make a backup of the dtsx-file before you edit in text/xml mode.

Running SQL Server 2008 R2

I faced the similar issue.

Deselect the check box ("In wizard deselect the checkbox stating "First row has columns names") and before running the wizard make sure you have opened your excel sheet.

Then run the wizard by deselecting the checkbox.

This resolved my issue.

It looks like some space include in the text. Use

lvTwoOrMoreOptions.SelectedItems[0].Text.ToString().Trim()

and convert to int32.

hope this code will solve you

From comments

if your ListView is in report mode (i.e. it looks like a grid) then you will need the SubItems property. lvTwoOrMoreOptions.SelectedItems gets you each items in the list view - SubItems gets you the columns. So lvTwoOrMoreOptions.SelectedItems[0].SubItems[0] is the first column value,

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

Try itext. Add dependency to your build.gradle for latest as of this post

Note: special version for android, trailing "g":

dependencies {
    compile 'com.itextpdf:itextg:5.5.9'
}

You can do this entirely with html and css and i have.

HTML First you give the div you wish to hide an ID to target like #view_element and a class to target like #hide_element. You can if you wish make both of these classes but i don't know if you can make them both IDs. Then have your Show button target your show id and your Hide button target your hide class. That is it for the html the hiding and showing is done in the CSS.

CSS The css to show and hide this should look something like this

#hide_element:target {
    display:none;
}

.show_element:target{
    display:block;
}

This should allow you to hide and show elements at will. This should work nicely on spans and divs.

Just add data-backdrop="static" and data-keyboard="false" attributes to that modal.

Eg.

<a data-controls-modal="your_div_id" data-backdrop="static" data-keyboard="false" href="#">

increase the response.getBufferSize() get the buffer size and compare with the bytes you want to transfer !

Java doesn't support the Net Framework. Java has its own Framework. Visual Studio used to support at one time J++ and J#, which were meant for Java developers who wanted to develop with the .Net, but since that has become extinct.

Most people when they want to develop java, they just go ahead and start with Netbeans, Eclipse, or something equivalent. They don't go around asking on sites like this if they could develop Java stuff in Visual Studio.

In my honest opinion, Java would not do very well in Visual Studio. Oracle and Microsoft are two separate entities and they need to remain that way. The only mix of Oracle and Microsoft I want to see is Java for Windows and Java development tools for Windows. I do not want to see Java in Visual Studio. It would get too confusing with C# lingering around the corner.

If you're able to successfully load a page from Eclipses internal web browser (by going to "Window"=>"Show View"=>"Other"=>"Internal Web Browser" and trying to open a page) BUT installing software from the eclipse marketplace and the "Help"=>"Install New Software" window are not working then this fix may help you (worked for me on a Windows 7 machine):

1. Go to "Window"=>"Preferences"=>"General"=>"Network Connections" and set the Active Provider to "Native".
2. Go into the Windows Control pannel and search firewall. Then select "Allow Program Through Windows Firewall" and click "Allow Other Program..." and add your eclipse installation.

3. Restart Eclipse and try refreshing a repository on the "Help"=>"Install New Software" window. It was able to successfull grab it for me.

For MySql Server 8.0 The default location is %WINDIR% or C:\Windows.

You need to add a "my.ini" file there.

Here's a sample of what I put in the ini file.

[mysqld]

secure_file_priv=""

Make sure to restart the MySQL service after that.

If you have your MySQL server up and running, then you just need a client to connect to it and start practicing. One is the mysql-client, which is a command-line tool, or you can use phpMyAdmin, which is a web-based tool.

In SQL Server Management Studio query window

1. Select All result set values
2. Right Click and Select "Save Results As"

3. Save as CSV file

Try This

myModal1 is the id of modal

$('#myModal1').modal({ show: true });

if is bootstrap 3 you can use:

$("#mimodal").on('hidden.bs.modal', function () {
    $(this).data('bs.modal', null);
});

If you are using Mac or even Linux, just copy and paste this onto the Terminal application and you will get the SHA1 key immediately. No need to change anything.

If you want to individually generate ddl for each object,

Queries are:

--GENERATE DDL FOR ALL USER OBJECTS

--1. FOR ALL TABLES

SELECT DBMS_METADATA.GET_DDL('TABLE', TABLE_NAME) FROM USER_TABLES;

--2. FOR ALL INDEXES

SELECT DBMS_METADATA.GET_DDL('INDEX', INDEX_NAME) FROM USER_INDEXES WHERE INDEX_TYPE ='NORMAL';

--3. FOR ALL VIEWS

SELECT DBMS_METADATA.GET_DDL('VIEW', VIEW_NAME) FROM USER_VIEWS;

OR

SELECT TEXT FROM USER_VIEWS

--4. FOR ALL MATERILIZED VIEWS

SELECT QUERY FROM USER_MVIEWS

--5. FOR ALL FUNCTION

SELECT DBMS_METADATA.GET_DDL('FUNCTION', OBJECT_NAME) FROM USER_PROCEDURES WHERE OBJECT_TYPE = 'FUNCTION'

===============================================================================================

GET_DDL Function doesnt support for some object_type like LOB,MATERIALIZED VIEW, TABLE PARTITION

SO, Consolidated query for generating DDL will be:

SELECT OBJECT_TYPE, OBJECT_NAME,DBMS_METADATA.GET_DDL(OBJECT_TYPE, OBJECT_NAME, OWNER)
  FROM ALL_OBJECTS 
  WHERE (OWNER = 'XYZ') AND OBJECT_TYPE NOT IN('LOB','MATERIALIZED VIEW', 'TABLE PARTITION') ORDER BY OBJECT_TYPE, OBJECT_NAME;

I find that psql.exe is quite picky with the slash direction, at least on windows (which the above looks like).

Here's an example. In a cmd window:

C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres
psql (9.2.4)
Type "help" for help.

postgres=# \i c:\temp\try1.sql    
c:: Permission denied
postgres=# \i c:/temp/try1.sql
CREATE TABLE
postgres=#

You can see it fails when I use "normal" windows slashes in a \i call. However both slash styles work if you pass them as input params to psql.exe, for example:

C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres -f c:\TEMP\try1.sql
CREATE TABLE

C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres -f c:/TEMP/try1.sql
CREATE TABLE

C:\Program Files\PostgreSQL\9.2\bin>

Try it:

<input type="button" value="Dont show this again! " onClick="fbLikeDump();WriteCookie();" />

Or also

<script>
function clickEvent(){
    fbLikeDump();
    WriteCookie();
}
</script>
<input type="button" value="Dont show this again! " onClick="clickEvent();" />

Try:

if(!$('#car2').is(':visible'))
{  
    alert('car 2 is hidden');       
}

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

Search for the server.xml file and check your <Context> tags, probably there are multiple definitions for the same path. Remove the duplicates and it should work for you.

Check out the answer here.

Auto-format the xml file (control + shift + f) since the second <Context> tag may be on the same line, but outside the viewport and really far away from the visible one.

Even though the question is quite fuzzy and the HTML snippet is quite limited, I suppose

.feature_desc {
    display: block;
}
.feature_desc:before {
    content: "";
    display: block;
}

might give you want you want to achieve without the <br/> element. Though it would help to see your CSS applied to these elements.

NOTE. The example above doesn't work in IE7 though.

With the last ADT, you can import Github project using Eclipse :

1. File -> Import -> Git -> Projects From Git > URI

2. Enter the Github repository url

3. Select the branch

You will need to use openssl.

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

The key file is just a text file with your private key in it.

If you have a root CA and intermediate certs, then include them as well using multiple -in params

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt -in intermediate.crt -in rootca.crt

You can install openssl from here: openssl

You can simply use adb install command to install/update APK silently. Sample code is below

public static void InstallAPK(String filename){
    File file = new File(filename); 
    if(file.exists()){
        try {   
            String command;
            filename = StringUtil.insertEscape(filename);
            command = "adb install -r " + filename;
            Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command });
            proc.waitFor();
        } catch (Exception e) {
        e.printStackTrace();
        }
     }
  }

If you want to configure your project logging using log4Net, while using a class library, There is no actual need of any config file. You can configure your log4net logger in a class and can use that class as library.

As log4net provides all the options to configure it.

Please find the code below.

public static void SetLogger(string pathName, string pattern)
        {
            Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();

            PatternLayout patternLayout = new PatternLayout();
            patternLayout.ConversionPattern = pattern;
            patternLayout.ActivateOptions();

            RollingFileAppender roller = new RollingFileAppender();
            roller.AppendToFile = false;
            roller.File = pathName;
            roller.Layout = patternLayout;
            roller.MaxSizeRollBackups = 5;
            roller.MaximumFileSize = "1GB";
            roller.RollingStyle = RollingFileAppender.RollingMode.Size;
            roller.StaticLogFileName = true;
            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);

            MemoryAppender memory = new MemoryAppender();
            memory.ActivateOptions();
            hierarchy.Root.AddAppender(memory);

            hierarchy.Root.Level = log4net.Core.Level.Info;
            hierarchy.Configured = true;
      }

Now instead of calling XmlConfigurator.Configure(new FileInfo("app.config")) you can directly call SetLogger with desired path and pattern to set the logger in Global.asax application start function.

And use the below code to log the error.

        public static void getLog(string className, string message)
        {
            log4net.ILog iLOG = LogManager.GetLogger(className);
            iLOG.Error(message);    // Info, Fatal, Warn, Debug
        }

By using following code you need not to write a single line neither in application web.config nor inside the app.config of library.

You can resave the image and literally find the src file of your project and add it to that when you save. For me I had to go to netbeans and found my project and when that comes up it had 3 files src was the last. Don't click on any of them just save your pic there. That should work. Now resizing it may be a different issue and one I'm working on now lol

Maybe Eclipse WTP plugin has been accidently removed. Have you tried re-installing WTP using this location ? If I were you I would have reinstall Eclipse from strach or even better try Spring ToolSuite which integrates with Google Plugin for Eclipse seamlessly (usign Extenstions tab on STS Dashboard)

Open .edmx file any text editor change the Schema="your required schema" and also open the app.config/web.config, change the user id and password from the connection string. you are done.

$("#wizard li").click(function () {
    console.log( $(this).index() );
});

However rather than attaching one click handler for each list item it is better (performance wise) to use delegate which would look like this:

$("#wizard").delegate('li', 'click', function () {
    console.log( $(this).index() );
});

In jQuery 1.7+, you should use on. The below example binds the event to the #wizard element, working like a delegate event:

$("#wizard").on("click", "li", function() {
    console.log( $(this).index() );
});

save the file on your disk and then use the following as URL:

file://your_path/your_file.wsdl

I tried @ScottK's approach, first as a side feature of my functional UDF, then as a standalone _Help suffix version when I ran into trouble (see below). In hindsight, the latter approach is better anyway--more obvious to a user attentive enough to see a tool tip, and it doesn't clutter up the functional code.

I figured if an inattentive user just typed the function name and closed the parentheses while he thought it over, help would appear and he would be on his way. But dumping a bunch of text into a single cell that I cannot format didn't seem like a good idea. Instead, When the function is entered in a cell with no arguments i.e.

   = interpolateLinear() 
or
   = interpolateLinear_Help()

a msgBox opens with the help text. A msgBox is limited to ~1000 characters, maybe it's 1024. But that's enough (barely 8^/) for my overly tricked out interpolation function. If it's not, you can always open a user form and go to town.

The first time the message box opened, it looked like success. But there are a couple of problems. First of course, the user has to know to enter the function with no arguments (+1 for the _Help suffix UDF).

The big problem is, the msgBox reopens several times in succession, spontaneously while working in unrelated parts of the workbook. Needless to say, it's very annoying. Sometimes it goes on until I get a circular reference warning. Go figure. If a UDF could change the cell formula, I would have done that to shut it up.

I don't know why Excel feels the need recalculate the formula over and over; neither the _Help standalone, nor the full up version (in help mode) has precedents or dependents. There's not an application.volatile statement anywhere. Of course the function returns a value to the calling cell. Maybe that triggers the recalc? But that's what UDFs do. I don't think you can not return a value.

Since you can't modify a worksheet formula from a UDF, I tried to return a specific string --a value --to the calling cell (the only one you can change the value of from a UDF), figuring I would inspect the cell value using application.caller on the next cycle, spot my string, and know not to re-display the help message. Seemed like a good idea at the time--didn't work. Maybe I did something stupid in my sleep-deprived state. I still like the idea. I'll update this when (if) I fix the problem. My quick fix was to add a line on the help box: "Seek help only in an emergency. Delete the offending formula to end the misery.

In the meantime, I tried the Application.MacroOptions approach. Pretty easy, and it looks professional. Just one problem to work out. I'll post a separate answer on that approach later.

1. Download MySQL Connector .NET (6.9.4 on this date) from here and install it CUSTOM!
2. Remove the ASP.NET WEB providers option or the installer will write in machine.config!
3. Download MySQL for Visual Studio from here and install it CUSTOM. Be sure to check the integration options. You need this step because after Connector .NET 6.7 the installer will no longer integrate the connector with Visual Studio. This installer can take longer then expected. This is it.

You can install it from alternate download here which should have integrated with VS correctly but it did not and I got a strange error and after the reinstall it is ok.

If the database is not very large, you might look at the 'Script Database' commands in SQL Server Management Studio Express, which are in a context menu off the database item itself in the explorer.

You can choose what all to script; you want the objects and the data, of course. You will then save the entire script to a single file. Then you can use that file to re-create the database; just make sure the USE command at the top is set to the proper database.

If I have open a package in BIDS ("Business Intelligence Development Studio", the tool you use to design the packages), and do not select any item in it, I have a "Properties" pane in the bottom right containing - among others, the MaximumErrorCount property. If you do not see it, maybe it is minimized and you have to open it (have a look at tabs in the right).

If you cannot find it this way, try the menu: View/Properties Window.

Or try the F4 key.

Old question but still relevant. I've generated a dictionary that gets the appropriate datetime format for each region, here is the helper class I generated:

https://github.com/anakic/ExcelDateTimeFormatHelper/blob/master/FormatHelper.cs

FWIW this is how I went about it:

1. opened excel, manually entered a datetime into the first cell of a workbook
2. opened the regions dialog in control panel
3. used Spy to find out the HWND's of the regions combobox and the apply button so I can use SetForegroundWindow and SendKey to change the region (couldn't find how to change region through the Windows API)
4. iterated through all regions and for each region asked Excel for the NumberFormat of the cell that contained the date, saved this data to into a file

You can also extract the event code from the HTML, like this :

<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>

<script>
function selectAll(frmElement, chkElement) {
    // ...
}
document.getElementById("check_all_1").onclick = function() {
    selectAll(document.wizard_form, this);
}
</script>

The key is "the order of the column should be the same"

Example:

create Table A (
    A_ID char(3) primary key,
    A_name char(10) primary key,
    A_desc desc char(50)
)

create Table B (
    B_ID char(3) primary key,
    B_A_ID char(3),
    B_A_Name char(10),
    constraint [Fk_B_01] foreign key (B_A_ID,B_A_Name) references A(A_ID,A_Name)
)

the column order on table A should be --> A_ID then A_Name; defining the foreign key should follow the same order as well.

Yes, presumably it wants the path to the javadoc command line tool that comes with the JDK (in the bin directory, same as java and javac).

Eclipse should be able to find it automatically; are you perhaps running it on a JRE? That would explain the request.

The length of a base64 encoded string is always a multiple of 4. If it is not a multiple of 4, then = characters are appended until it is. A query string of the form ?name=value has problems when the value contains = charaters (some of them will be dropped, I don't recall the exact behavior). You may be able to get away with appending the right number of = characters before doing the base64 decode.

Edit 1

You may find that the value of UserNameToVerify has had "+"'s changed to " "'s so you may need to do something like so:

a = a.Replace(" ", "+");

This should get the length right;

int mod4 = a.Length % 4;
if (mod4 > 0 )
{
    a += new string('=', 4 - mod4);
}

Of course calling UrlEncode (as in LukeH's answer) should make this all moot.

Right click on the Project name > Configure > Convert to Maven Project > click finish. Here you will add some dependencies to download and add your expected jar file.

This will create an auto-generated pom.xml file. Open that file in xml format in your eclipse editor. After build tag (</build>) add your dependencies which you can copy from maven website and add them there. Now you are good to go. These dependencies will automatically add your required jar files.

Had the same problem (but with Maven). The reason was incorrect choice of executor: my project used global settings that are not avilable from Embedded installation of Maven. Changed it to external (Window -> Preferences -> Maven -> Installations) and that fixed the problem.

VMDK/VMX are VMWare file formats but you can use it with VirtualBox:

1. Create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk"
2. Click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
3. Then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

And just to help possible new readers, another reason may be errors in the manifest file. I had mistyped android:service as android.service and ran into the same error...

Probably won't help but you could try creating a CSV table with that content:

DROP TABLE IF EXISTS foo_export;
CREATE TABLE foo_export LIKE foo;
ALTER TABLE foo_export ENGINE=CSV;
INSERT INTO foo_export SELECT id, 
   client,
   project,
   task,
   REPLACE(REPLACE(ifnull(ts.description,''),'\n',' '),'\r',' ') AS description, 
   time,
   date
  FROM ....

If you deployed the package to the "Integration Services Catalog" on SSMS you can retrieve the package using Visual studio.

first of all look at your gen file if it contains your package name and R.java or no. if it was empty maybe you don't have permission to create new files so exit eclipse than right click, run as administrator and clean your project and everything will be correct.

otherwise you should have an error in your XML file maybe or check the other answers.

One thing that isn't mentioned in the accepted answer is that the "IMEX=1" parameter has to go inside the quoted portion of:

...;Extended Properties="...";

You can also do this with named ranges so you don't have to copy the cells from Sheet1 to Sheet2:

1. Define a named range, say Sheet1Vals for the column that has the values on which you want to base your condition. You can define a new named range by using the Insert\Name\Define... menu item. Type in your name, then use the cell browser in the Refers to box to select the cells you want in the range. If the range will change over time (add or remove rows) you can use this formula instead of selecting the cells explicitly:

   =OFFSET('SheetName'!$COL$ROW,0,0,COUNTA('SheetName'!$COL:$COL)).

   Add a -1 before the last ) if the column has a header row.

2. Define a named range, say Sheet2Vals for the column that has the values you want to conditionally format.

3. Use the Conditional Formatting dialog to create your conditions. Specify Formula Is in the dropdown, then put this for the formula:

   =INDEX(Sheet1Vals, MATCH([FirstCellInRange],Sheet2Vals))=[Condition]

   where [FirstCellInRange] is the address of the cell you want to format and [Condition] is the value your checking.

For example, if my conditions in Sheet1 have the values of 1, 2 and 3 and the column I'm formatting is column B in Sheet2 then my conditional formats would be something like:

=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=1
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=2
=INDEX(Sheet1Vals, MATCH(B1,Sheet2Vals))=3

You can then use the format painter to copy these formats to the rest of the cells.

If the were checked as plugin-projects, than you just need to check them out. But do not select the "trunk"(for example) to speed it up. You must select all the projects you want to check out and proceed. Eclipse will than recognize them as such.

go
sp_configure 'show advanced options',1  
reconfigure with override  
go  
sp_configure 'Ad Hoc Distributed Queries',1  
reconfigure with override  
go
SELECT * into temptable
FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
                'Excel 8.0;Database=C:\Documents and Settings\abhisharma\Desktop\exl\ImportExcel2SQLServer\ImportExcel2SQLServer\example.xls;IMEX=1',
                'SELECT * FROM [Sheet1$]')

select * from temptable

Add a line to your app.config in the configSections element

<configSections>
 <section name="log4net" 
   type="log4net.Config.Log4NetConfigurationSectionHandler, log4net, Version=1.2.10.0, 
         Culture=neutral, PublicKeyToken=1b44e1d426115821" />
</configSections>

Then later add the log4Net section, but delegate to the actual log4Net config file elsewhere...

<log4net configSource="Config\Log4Net.config" />

In your application code, when you create the log, write

private static ILog GetLog(string logName)
{
    ILog log = LogManager.GetLogger(logName);
    return log;
}

A far more clear solution is to use the command netsh to change the IP (or setting it back to DHCP)

netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0

Where "Local Area Connection" is the name of the network adapter. You could find it in the windows Network Connections, sometimes it is simply named "Ethernet".

Here are two methods to set the IP and also to set the IP back to DHCP "Obtain an IP address automatically"

public bool SetIP(string networkInterfaceName, string ipAddress, string subnetMask, string gateway = null)
{
    var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
    var ipProperties = networkInterface.GetIPProperties();
    var ipInfo = ipProperties.UnicastAddresses.FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork);
    var currentIPaddress = ipInfo.Address.ToString();
    var currentSubnetMask = ipInfo.IPv4Mask.ToString();
    var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;

    if (!isDHCPenabled && currentIPaddress == ipAddress && currentSubnetMask == subnetMask)
        return true;    // no change necessary

    var process = new Process
    {
        StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" static {ipAddress} {subnetMask}" + (string.IsNullOrWhiteSpace(gateway) ? "" : $"{gateway} 1")) { Verb = "runas" }
    };
    process.Start();
    var successful = process.ExitCode == 0;
    process.Dispose();
    return successful;
}

public bool SetDHCP(string networkInterfaceName)
{
    var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
    var ipProperties = networkInterface.GetIPProperties();
    var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;

    if (isDHCPenabled)
        return true;    // no change necessary

    var process = new Process
    {
        StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" dhcp") { Verb = "runas" }
    };
    process.Start();
    var successful = process.ExitCode == 0;
    process.Dispose();
    return successful;
}

Note that including the UTF-8 BOM is not necessarily a good idea - Mac versions of Excel ignore it and will actually display the BOM as ASCII… three nasty characters at the start of the first field in your spreadsheet…

I don't believe there is a direct supported way. However, if you are desparate, then under navigation options, select to show system objects. Then in your table list, system tables will appear. Two tables are of interest here: MSysIMEXspecs and MSysIMEXColumns. You'll be able edit import and export information. Good luck!

I know this is an old question, but our solution is much simpler than what I see here. We use it for WCF calls with VS2010 and up. The string url can come from app settings or another source. In my case it is a drop down list where the user picks the server. TheService was configured through VS add service reference.

private void CallTheService( string url )
{
   TheService.TheServiceClient client = new TheService.TheServiceClient();
   client.Endpoint.Address = new System.ServiceModel.EndpointAddress(url);
   var results = client.AMethodFromTheService();
}

With JavaScript (here jQuery), you can disable the prev button before submitting the form.

$('form').on('keypress', function(event) {
    if (event.which == 13) {
        $('input[name="prev"]').prop('type', 'button');
    }
});

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

The correct approach is to use a single timer. Using setInterval, you can achieve what you want as follows:

window.onload = function start() {
    slide();
}
function slide() {
    var num = 0, style = document.getElementById('container').style;
    window.setInterval(function () {
        // increase by num 1, reset to 0 at 4
        num = (num + 1) % 4;

        // -600 * 1 = -600, -600 * 2 = -1200, etc 
        style.marginLeft = (-600 * num) + "px"; 
    }, 3000); // repeat forever, polling every 3 seconds
}

Convert them into Bitmaps and then either store them in a Collection(HashMap,List etc.) or you can write them on the SDcard.

When storing them in application space using the first approach, you might want to wrap them around a java.lang.ref.SoftReference specifically if their numbers is large (so that they are garbage collected during crisis). This could ensue a Reload though.

HashMap<String,SoftReference<Bitmap>> imageCache =
        new HashMap<String,SoftReference<Bitmap>>();

writing them on SDcard will not require a Reload; just a user-permission.

Look at this:

   <script>
function f(a){
  alert(typeof(a));
  if (a==null) alert('null');
  a?alert(true):alert(false);
}
</script>
                                          //return:
<button onclick="f()">nothing</button>    //undefined    null    false
<button onclick="f(null)">null</button>   //object       null    false
<button onclick="f('')">empty</button>    //string               false
<button onclick="f(0)">zero</button>      //number               false
<button onclick="f(1)">int</button>       //number               true
<button onclick="f('x')">str</button>     //string               true

It'll be because response[0] itself is undefined.

Ternary operators are just shorthand. They compile into the equivalent if-else statement, meaning they will be exactly the same.

One can also use the command line utilities included in poppler-utils package:

sudo apt-get install poppler-utils
pdftoppm --help
pdftocairo --help

Example:

pdftocairo -png mypage.pdf mypage.png

This is my solution, for any list object you can use this code for convert to xml layout. KeyFather is your principal tag and KeySon is where start your Forech.

public string BuildXml<T>(ICollection<T> anyObject, string keyFather, string keySon)
    {
        var settings = new XmlWriterSettings
        {
            Indent = true
        };
        PropertyDescriptorCollection props = TypeDescriptor.GetProperties(typeof(T));
        StringBuilder builder = new StringBuilder();
        using (XmlWriter writer = XmlWriter.Create(builder, settings))
        {
            writer.WriteStartDocument();
            writer.WriteStartElement(keyFather);
            foreach (var objeto in anyObject)
            {
                writer.WriteStartElement(keySon);
                foreach (PropertyDescriptor item in props)
                {
                    writer.WriteStartElement(item.DisplayName);
                    writer.WriteString(props[item.DisplayName].GetValue(objeto).ToString());
                    writer.WriteEndElement();
                }
                writer.WriteEndElement();
            }
            writer.WriteFullEndElement();
            writer.WriteEndDocument();
            writer.Flush();
            return builder.ToString();
        }
    }

Your Hash key (primary of sort) has to be unique (unless you have a range like stated by others).

In your case, to query your table you should have a secondary index.

|  ID  | DataID | Created | Data |
|------+--------+---------+------|
| hash | xxxxx  | 1234567 | blah |

Your Hash Key is ID Your secondary index is defined as: DataID-Created-index (that's the name that DynamoDB will use)

Then, you can make a query like this:

var params = {
    TableName: "Table",
    IndexName: "DataID-Created-index",
    KeyConditionExpression: "DataID = :v_ID AND Created > :v_created",
    ExpressionAttributeValues: {":v_ID": {S: "some_id"},
                                ":v_created": {N: "timestamp"}
    },
    ProjectionExpression: "ID, DataID, Created, Data"
};

ddb.query(params, function(err, data) {
    if (err) 
        console.log(err);
    else {
        data.Items.sort(function(a, b) {
            return parseFloat(a.Created.N) - parseFloat(b.Created.N);
        });
        // More code here
    }
});

Essentially your query looks like:

SELECT * FROM TABLE WHERE DataID = "some_id" AND Created > timestamp;

The secondary Index will increase the read/write capacity units required so you need to consider that. It still is a lot better than doing a scan, which will be costly in reads and in time (and is limited to 100 items I believe).

This may not be the best way of doing it but for someone used to RD (I'm also used to SQL) it's the fastest way to get productive. Since there is no constraints in regards to schema, you can whip up something that works and once you have the bandwidth to work on the most efficient way, you can change things around.

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:

https://<region>.amazonaws.com/<bucket-name>/<key>

Where <region> is something like s3-ap-southeast-2.

Click on the item in the S3 GUI to get the link for your bucket.

If you don't really like nested functions, you can also iterate over the keys:

myMap : Map<string, boolean>;
for(let key of myMap) {
   if (myMap.hasOwnProperty(key)) {
       console.log(JSON.stringify({key: key, value: myMap[key]}));
   }
}

Note, you have to filter out the non-key iterations with the hasOwnProperty, if you don't do this, you get a warning or an error.

Dijkstra's algorithm applies more to weighted paths and it sounds like the poster was wanting to find all paths, not just the shortest.

For this application, I'd build a graph (your application sounds like it wouldn't need to be directed) and use your favorite search method. It sounds like you want all paths, not just a guess at the shortest one, so use a simple recursive algorithm of your choice.

The only problem with this is if the graph can be cyclic.

With the connections:

• 1, 2
• 1, 3
• 2, 3
• 2, 4

While looking for a path from 1->4, you could have a cycle of 1 -> 2 -> 3 -> 1.

In that case, then I'd keep a stack as traversing the nodes. Here's a list with the steps for that graph and the resulting stack (sorry for the formatting - no table option):

current node (possible next nodes minus where we came from) [stack]

1. 1 (2, 3) [1]
2. 2 (3, 4) [1, 2]
3. 3 (1) [1, 2, 3]
4. 1 (2, 3) [1, 2, 3, 1] //error - duplicate number on the stack - cycle detected
5. 3 () [1, 2, 3] // back-stepped to node three and popped 1 off the stack. No more nodes to explore from here
6. 2 (4) [1, 2] // back-stepped to node 2 and popped 1 off the stack.
7. 4 () [1, 2, 4] // Target node found - record stack for a path. No more nodes to explore from here
8. 2 () [1, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes to explore from here
9. 1 (3) [1] //back-stepped to node 1 and popped 2 off the stack.
10. 3 (2) [1, 3]
11. 2 (1, 4) [1, 3, 2]
12. 1 (2, 3) [1, 3, 2, 1] //error - duplicate number on the stack - cycle detected
13. 2 (4) [1, 3, 2] //back-stepped to node 2 and popped 1 off the stack
14. 4 () [1, 3, 2, 4] Target node found - record stack for a path. No more nodes to explore from here
15. 2 () [1, 3, 2] //back-stepped to node 2 and popped 4 off the stack. No more nodes
16. 3 () [1, 3] // back-stepped to node 3 and popped 2 off the stack. No more nodes
17. 1 () [1] // back-stepped to node 1 and popped 3 off the stack. No more nodes
18. Done with 2 recorded paths of [1, 2, 4] and [1, 3, 2, 4]

With PHP 5.3, you can now do this:

function doIt($callback) { $callback(); }

doIt(function() {
    // this will be done
});

Finally a nice way to do it. A great addition to PHP, because callbacks are awesome.

In C++-11 you can do:

std::vector<int> v = {0, 1, 2, 3, 4, 5};
for (auto i : v)
{
   // access by value, the type of i is int
   std::cout << i << ' ';
}
std::cout << '\n';

Ideone supports Python 2.6 and Python 3

Try the outline property W3Schools - CSS Outline

Outline will not interfere with widths and lenghts of the elements/divs!

Please click the link I provided at the bottom to see working demos of the the different ways you can make borders, and inner/inline borders, even ones that do not disrupt the dimensions of the element! No need to add extra divs every time, as mentioned in another answer!

You can also combine borders with outlines, and if you like, box-shadows (also shown via link)

<head>
   <style type="text/css" ref="stylesheet">
      div {
        width:22px;
        height:22px;
        outline:1px solid black;
      }
   </style>
</head>
<div>
    outlined
</div>

Usually by default, 'border:' puts the border on the outside of the width, measurement, adding to the overall dimensions, unless you use the 'inset' value:

div {border: inset solid 1px black};

But 'outline:' is an extra border outside of the border, and of course still adds extra width/length to the element.

Hope this helps

PS: I also was inspired to make this for you : Using borders, outlines, and box-shadows

Put and Patch method are similar . But in rails it has different metod If we want to update/replace whole record then we have to use Put method. If we want to update particular record use Patch method.

Maybe you can use measure:

measureProgressBar() {
    this.refs.welcome.measure(this.logProgressBarLayout);
},

logProgressBarLayout(ox, oy, width, height, px, py) {
  console.log("ox: " + ox);
  console.log("oy: " + oy);
  console.log("width: " + width);
  console.log("height: " + height);
  console.log("px: " + px);
  console.log("py: " + py);
}

Putting these lines at the starting of the code will tell your operating systems to look up the binary program needed for the execution of the python script i.e it is the python interpreter.

So it depends on your operating system where it keeps the python interpreter. As I have Ubuntu as operating system it keeps the python interpreter in /usr/bin/python so I have to write this line at the starting of my python script;

#!/usr/bin/python

After completing and saving your code

1. Start your command terminal

2. Make sure the script lies in your present working directory

3. Type chmod +x script_name.py

4. Now you can start the script by clicking the script. An alert box will appear; press "Run" or "Run in Terminal" in the alert box; or, at the terminal prompt, type ./script_name.py

I try dismis progress on method onPageFinished(), but not good too much, it has time delay to render webview.

try with onPageCommitVisible() better:

val progressBar = ProgressDialog(context)
    progressBar.setCancelable(false)
    progressBar.show()
    val url = "your url here"
    web_container.settings.javaScriptEnabled = true
    web_container.loadUrl(url)

    web_container.webViewClient = object : WebViewClient() {
        override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
            view.loadUrl(url)
            progressBar.show()
            return true
        }

        override fun onPageFinished(view: WebView?, url: String?) {
            super.onPageFinished(view, url)
        }
        override fun onPageCommitVisible(view: WebView?, url: String?) {
            super.onPageCommitVisible(view, url)
            progressBar.dismiss()
        }
    }
    web_container.setOnKeyListener(View.OnKeyListener { _, keyCode, event ->
        if (keyCode == KEYCODE_BACK && event.action == MotionEvent.ACTION_UP
                && web_container.canGoBack()) {
            web_container.goBack()
            return@OnKeyListener true
        }
        return@OnKeyListener false
    })

You can just use the View.setId(integer) for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views you add programmatically.

According to View documentation

The identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.

So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

I ran into this error on a fresh build of Windows Server 2012 R2. IIS and .NET 4.5 had been installed, but the ASP.NET Server Role (version 4.5 in my case) had not been added. Make sure that the version of ASP.NET you need has been added/installed like ASP.NET 4.5 is in this screenshot.

Reset the file in a correct state, commit, and push again.

If you're sure nobody else has fetched your changes yet, you can use --amend when committing, to modify your previous commit (i.e. rewrite history), and then push. I think you'll have to use the -f option when pushing, to force the push, though.

Neither of the posted answers worked for me. Setting position: absolute for the child element did work however.

Try:

SELECT MEMBSHIP_ID
  FROM user_payment
 WHERE user_id=1 
ORDER BY paym_date = (select MAX(paym_date) from user_payment and user_id=1);

Or:

SELECT MEMBSHIP_ID
FROM (
  SELECT MEMBSHIP_ID, row_number() over (order by paym_date desc) rn
      FROM user_payment
     WHERE user_id=1 )
WHERE rn = 1

Re jcoby's answer:

bytea being a "normal" column also means the value being read completely into memory when you fetch it. Blobs, in contrast, you can stream into stdout. That helps in reducing the server memory footprint. Especially, when you store 4-6 MPix images.

No problem with backing up blobs. pg_dump provides "-b" option to include the large objects into the backup.

So, I prefer using pg_lo_*, you may guess.

Re Kris Erickson's answer:

I'd say the opposite :). When images are not the only data you store, don't store them on the file system unless you absolutely have to. It's such a benefit to be always sure about your data consistency, and to have the data "in one piece" (the DB). BTW, PostgreSQL is great in preserving consistency.

However, true, reality is often too performance-demanding ;-), and it pushes you to serve the binary files from the file system. But even then I tend to use the DB as the "master" storage for binaries, with all the other relations consistently linked, while providing some file system-based caching mechanism for performance optimization.

Alternatively you can do like this.

RUN addgroup demo && adduser -DH -G demo demo

First command creates group called demo. Second command creates demo user and adds him to previously created demo group.

Flags stands for:

-G Group
-D Don't assign password
-H Don't create home directory

If you're working with new versions of Django (>10) and don't want to spend time writing the model definition. you can use the ogrinspect tool.

This will create a code definition for the model .

python manage.py ogrinspect [/path/to/thecsv] Product

The output will be the class (model) definition. In this case the model will be called Product. You need to copy this code into your models.py file.

Afterwards you need to migrate (in the shell) the new Product table with:

python manage.py makemigrations
python manage.py migrate

More information here: https://docs.djangoproject.com/en/1.11/ref/contrib/gis/tutorial/

Do note that the example has been done for ESRI Shapefiles but it works pretty good with standard CSV files as well.

For ingesting your data (in CSV format) you can use pandas.

import pandas as pd
your_dataframe = pd.read_csv(path_to_csv)
# Make a row iterator (this will go row by row)
iter_data = your_dataframe.iterrows()

Now, every row needs to be transformed into a dictionary and use this dict for instantiating your model (in this case, Product())

# python 2.x
map(lambda (i,data) : Product.objects.create(**dict(data)),iter_data

Done, check your database now.

Ok, I figured it out. I just wrapped it in a try catch and send back null.

    public String test() {
            String cert=null;
            String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN 
                     where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
            try {
                Object o = (String) jdbc.queryForObject(sql, String.class);
                cert = (String) o;
            } catch (EmptyResultDataAccessException e) {
                e.printStackTrace();
            }
            return cert;
    }

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

To do this for multiple dataframes, you can do a for loop over them:

fig = plt.figure(num=None, figsize=(10, 8))
ax = dict_of_dfs['FOO'].column.plot()
for BAR in dict_of_dfs.keys():
    if BAR == 'FOO':
        pass
    else:
        dict_of_dfs[BAR].column.plot(ax=ax)

As a simple alternative, that does not require $.when.apply or an array, you can use the following pattern to generate a single promise for multiple parallel promises:

promise = $.when(promise, anotherPromise);

e.g.

function GetSomeDeferredStuff() {
    // Start with an empty resolved promise (or undefined does the same!)
    var promise;
    var i = 1;
    for (i = 1; i <= 5; i++) {
        var count = i;

        promise = $.when(promise,
        $.ajax({
            type: "POST",
            url: '/echo/html/',
            data: {
                html: "<p>Task #" + count + " complete.",
                delay: count / 2
            },
            success: function (data) {
                $("div").append(data);
            }
        }));
    }
    return promise;
}

$(function () {
    $("a").click(function () {
        var promise = GetSomeDeferredStuff();
        promise.then(function () {
            $("div").append("<p>All done!</p>");
        });
    });
});

Notes:

• I figured this one out after seeing someone chain promises sequentially, using promise = promise.then(newpromise)
• The downside is it creates extra promise objects behind the scenes and any parameters passed at the end are not very useful (as they are nested inside additional objects). For what you want though it is short and simple.
• The upside is it requires no array or array management.

Try this solution:

There is a data item in your table whose associated value doesn't exist in the table you want to use it as a primary key table. Make your table empty or add the associated value to the second table.

You can use RequestDispatcher as you usually use it in Servlet:

<%@ page contentType="text/html"%>
<%@ page import = "javax.servlet.RequestDispatcher" %>
<%
     RequestDispatcher rd = request.getRequestDispatcher("/yourServletUrl");
     request.setAttribute("msg","HI Welcome");
     rd.forward(request, response);
%>

Always be aware that don't commit any response before you use forward, as it will lead to IllegalStateException.

SELECT s.name + '.' + ao.name
       , s.name
FROM sys.all_objects ao
INNER JOIN sys.schemas s ON s.schema_id = ao.schema_id
WHERE ao.type='u';

You can use any of these two:

return redirect()->back()->withInput(Input::all())->with('message', 'Some message');

Or,

return redirect('url_goes_here')->withInput(Input::all())->with('message', 'Some message');

If Template is not set (i.e. ==null), this error will be raised, too.

More comments:

If you know the parameter value by the time you add parameters, you can also use AddWithValue

The EXEC is not required. You can reference the @template parameter in the SELECT directly.

Using the C++ API, the function name has slightly changed and it writes now:

#include <opencv2/imgproc/imgproc.hpp>

cv::Mat greyMat, colorMat;
cv::cvtColor(colorMat, greyMat, CV_BGR2GRAY);

The main difficulties are that the function is in the imgproc module (not in the core), and by default cv::Mat are in the Blue Green Red (BGR) order instead of the more common RGB.

OpenCV 3

Starting with OpenCV 3.0, there is yet another convention. Conversion codes are embedded in the namespace cv:: and are prefixed with COLOR. So, the example becomes then:

#include <opencv2/imgproc/imgproc.hpp>

cv::Mat greyMat, colorMat;
cv::cvtColor(colorMat, greyMat, cv::COLOR_BGR2GRAY);

As far as I have seen, the included file path hasn't changed (this is not a typo).

The default value of any Object, such as Boolean, is null.

The default value for a boolean is false.

Note: Every primitive has a wrapper class. Every wrapper uses a reference which has a default of null. Primitives have different default values:

boolean -> false

byte, char, short, int, long -> 0

float, double -> 0.0

Note (2): void has a wrapper Void which also has a default of null and is it's only possible value (without using hacks).

REST

Resource is a RESTful subset of Endpoint.

An endpoint by itself is the location where a service can be accessed:

https://www.google.com    # Serves HTML
8.8.8.8                   # Serves DNS
/services/service.asmx    # Serves an ASP.NET Web Service

A resource refers to one or more nouns being served, represented in namespaced fashion, because it is easy for humans to comprehend:

/api/users/johnny         # Look up johnny from a users collection.
/v2/books/1234            # Get book with ID 1234 in API v2 schema.

All of the above could be considered service endpoints, but only the bottom group would be considered resources, RESTfully speaking. The top group is not expressive regarding the content it provides.

A REST request is like a sentence composed of nouns (resources) and verbs (HTTP methods):

• GET (method) the user named johnny (resource).
• DELETE (method) the book with id 1234 (resource).

Non-REST

Endpoint typically refers to a service, but resource could mean a lot of things. Here are some examples of resource that are dependent on the context they're used in.

URL: Uniform "Resource" Locator

• Could be RESTful, but often is not. In this case, endpoint is almost synonymous.

Resource Management

• In GCP / AWS, resource is used in reference to cloud infrastructure.
• In general computing, a resource is a reference to a component with limited availability.

Dictionary

• The definitions provide many more uses of the word.

Something that can be used to help you:

The library was a valuable resource, and he frequently made use of it.

Resources are natural substances such as water and wood which are valuable in supporting life:

[ pl ] The earth has limited resources, and if we don’t recycle them we use them up.

Resources are also things of value such as money or possessions that you can use when you need them:

[ pl ] The government doesn’t have the resources to hire the number of teachers needed.

The Moral

The term resource by definition has a lot of nuance. It all depends on the context its used in.

i use concantenate. works for me.

1. fill j2-j14 with '(appostrophe)
2. enter L2 with formula =concantenate(j2,k2)
3. copy L2 to L3-L14

Make sure that you are using SSH instead of http. Check this SO answer.

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

No, the underscore is the only continuation character. Personally I prefer the occasional use of a continuation character to being forced to use it always as in C#, but apart from the comments issue (which I'd agree is sometimes annoying), getting things to line up is not an issue.

With VS2008 at any rate, just select the second and following lines, hit the tab key several times, and it moves the whole lot across.

If it goes a tiny bit too far, you can delete the excess space a character at a time. It's a little fiddly, but it stays put once it's saved.

On the rare cases where this isn't good enough, I sometimes use the following technique to get it all to line up:

dim results as String = ""
results += "from a in articles "
results += "where a.articleID = 4 " 'and now you can add comments
results += "select a.articleName"

It's not perfect, and I know those that prefer C# will be tut-tutting, but there it is. It's a style choice, but I still prefer it to endless semi-colons.

Now I'm just waiting for someone to tell me I should have used a StringBuilder ;-)

There are some very good answers here. I'd like to add the following here as well:

some_dict = {
    "foo": "bar",
    "lorem": "ipsum"
}

for index, (key, value) in enumerate(some_dict.items()):
    print(index, key, value)

results in

0 foo bar
1 lorem ipsum

Appears to work with Python 2.7 and 3.5

Just use window.open():

window.open('Prosjektplan.pdf')

Anyway, what guys are saying on comments is true. You better use <a target="_blank"> instead of click events.

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

public function index() {

    $user = $this->session->userdata("username");
    $file_path = "./images/" . $user . '/';

    if (isset($_FILES['multipleUpload'])) {

        if (!is_dir('images/' . $user)) {
            mkdir('./images/' . $user, 0777, TRUE);
        }

        $files = $_FILES;
        $cpt = count($_FILES ['multipleUpload'] ['name']);

        for ($i = 0; $i < $cpt; $i ++) {

            $name = time().$files ['multipleUpload'] ['name'] [$i];
            $_FILES ['multipleUpload'] ['name'] = $name;
            $_FILES ['multipleUpload'] ['type'] = $files ['multipleUpload'] ['type'] [$i];
            $_FILES ['multipleUpload'] ['tmp_name'] = $files ['multipleUpload'] ['tmp_name'] [$i];
            $_FILES ['multipleUpload'] ['error'] = $files ['multipleUpload'] ['error'] [$i];
            $_FILES ['multipleUpload'] ['size'] = $files ['multipleUpload'] ['size'] [$i];

            $this->upload->initialize($this->set_upload_options($file_path));
            if(!($this->upload->do_upload('multipleUpload')) || $files ['multipleUpload'] ['error'] [$i] !=0)
            {
                print_r($this->upload->display_errors());
            }
            else
            {
                $this->load->model('uploadModel','um');
                $this->um->insertRecord($user,$name);
            }
        }
    } else {
        $this->load->view('uploadForm');
    }
}

public function set_upload_options($file_path) {
    // upload an image options
    $config = array();
    $config ['upload_path'] = $file_path;
    $config ['allowed_types'] = 'gif|jpg|png';
    return $config;
}

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

Here's my code for adding a new row to a two-column TableLayoutColumn:

private void AddRow(Control label, Control value)
{
    int rowIndex = AddTableRow();
    detailTable.Controls.Add(label, LabelColumnIndex, rowIndex);
    if (value != null)
    {
        detailTable.Controls.Add(value, ValueColumnIndex, rowIndex);
    }
}

private int AddTableRow()
{
    int index = detailTable.RowCount++;
    RowStyle style = new RowStyle(SizeType.AutoSize);
    detailTable.RowStyles.Add(style);
    return index;
}

The label control goes in the left column and the value control goes in the right column. The controls are generally of type Label and have their AutoSize property set to true.

I don't think it matters too much, but for reference, here is the designer code that sets up detailTable:

this.detailTable.ColumnCount = 2;
this.detailTable.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle());
this.detailTable.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle());
this.detailTable.Dock = System.Windows.Forms.DockStyle.Fill;
this.detailTable.Location = new System.Drawing.Point(0, 0);
this.detailTable.Name = "detailTable";
this.detailTable.RowCount = 1;
this.detailTable.RowStyles.Add(new System.Windows.Forms.RowStyle());
this.detailTable.Size = new System.Drawing.Size(266, 436);
this.detailTable.TabIndex = 0;

This all works just fine. You should be aware that there appear to be some problems with disposing controls from a TableLayoutPanel dynamically using the Controls property (at least in some versions of the framework). If you need to remove controls, I suggest disposing the entire TableLayoutPanel and creating a new one.

Operator? NO, but I think you can change your culture so that string comparison is not case-sensitive.

// you'll want to change this...
System.Threading.Thread.CurrentThread.CurrentCulture
// and you'll want to custimize this
System.Globalization.CultureInfo.CompareInfo

I'm confident that it will change the way that strings are being compared by the equals operator.

Use the debugging tools supported by the browser. As mentioned above Firebug for Firefox Chrome Developer Tools from Chrome IE Developer for IE.

That way you can detect cross-browser issues. To help reduce the cross-browser issues, use a javascript framework ie jQuery, YUI, moo tools, etc.

Below is a screenshot (javascript-debug.png) of what it looks lime in Firebug.
1) hit 'F12'
2) click the 'Script' tab and 'enable it' (if you are already on your page - hit 'F5' to re-load)
3) next to the 'All' drop down, there will be another dropdown to the right. Select your javascript file from that dropdown.
In the screenshot, I've set a break-point at line 42 by 'left-mouse-click'. This will enable you to break, inspect, watch, etc.

number.parseFloat(2) works but it returns a string.

If you'd like to preserve it as a number type you can use:

Math.round(number * 100) / 100

After updating to ADT 22.0.1, due to Android private libraries, the Google Maps service was giving some error and the app crashed. So I found the solution finally and it worked for me.

Just install the Google Play service library and then go to google-play-service/libproject/google-play-services_lib from https://www.dropbox.com/sh/2ok76ep7lmav0qf/9XVlv61D2b. Import that into your workspace. Clean your project where you want to use gogole-play-services-lib and then build it again and go to the Project -> Properties -> Java BuildPath -> select "Android Private Libraries, Android Dependencies, google-play-service"

In Properties itself, go to Android and then choose any of the versions and then choose add and select google-play-service-lib and then press apply and finally OK.

At last, go to the Project -> Android Tools -> Android Support Libraries. Accept the license and after installing then run your project.

It will work fine.

It looks like the latest version of anaconda forces install of pyqt5.6 over any pyqt build, which will be fatal for your applications. In a terminal, Try:

conda install -c anaconda pyqt=4.11.4

It will prompt to downgrade conda client. After that, it should be good.

UPDATE: If you want to know what pyqt versions are available for install, try:

conda search pyqt

UPDATE: The most recent version of conda installs anaconda-navigator. This depends on qt5, and should first be removed:

conda uninstall anaconda-navigator

Then install "newest" qt4:

conda install qt=4

IF you know the width of the container, you could do like this:

#container
  width: #{200}px
  #element
    width: #{(0.25 * 200) - 5}px

I'm aware that in many cases #container could have a relative width. Then this wouldn't work.

1. Go to Control Panel -> Programs -> Programs and features

   

2. Go to Windows Features and disable Internet Explorer 11

   

   

3. Then click on Display installed updates

   

4. Search for Internet explorer

5. Right-click on Internet Explorer 11 -> Uninstall

   

6. Do the same with Internet Explorer 10

7. Restart your computer
8. Install Internet Explorer 10 here (old broken link)

I think it will be okay.

A simpler approach like the one Ioannis Filippidis do :

import matplotlib.pyplot as plt
import numpy as np

# evenly sampled time at 200ms intervals
tMin=-1 ;tMax=10
t = np.arange(tMin, tMax, 0.1)

# red dashes, blue points default
plt.plot(t, 22*t, 'r--', t, t**2, 'b')

factor=3/4 ;offset=20  # text position in view  
textPosition=[(tMax+tMin)*factor,22*(tMax+tMin)*factor]
plt.text(textPosition[0],textPosition[1]+offset,'22  t',color='red',fontsize=20)
textPosition=[(tMax+tMin)*factor,((tMax+tMin)*factor)**2+20]
plt.text(textPosition[0],textPosition[1]+offset, 't^2', bbox=dict(facecolor='blue', alpha=0.5),fontsize=20)
plt.show()

The main differences between InnoDB and MyISAM ("with respect to designing a table or database" you asked about) are support for "referential integrity" and "transactions".

If you need the database to enforce foreign key constraints, or you need the database to support transactions (i.e. changes made by two or more DML operations handled as single unit of work, with all of the changes either applied, or all the changes reverted) then you would choose the InnoDB engine, since these features are absent from the MyISAM engine.

Those are the two biggest differences. Another big difference is concurrency. With MyISAM, a DML statement will obtain an exclusive lock on the table, and while that lock is held, no other session can perform a SELECT or a DML operation on the table.

Those two specific engines you asked about (InnoDB and MyISAM) have different design goals. MySQL also has other storage engines, with their own design goals.

So, in choosing between InnoDB and MyISAM, the first step is in determining if you need the features provided by InnoDB. If not, then MyISAM is up for consideration.

A more detailed discussion of differences is rather impractical (in this forum) absent a more detailed discussion of the problem space... how the application will use the database, how many tables, size of the tables, the transaction load, volumes of select, insert, updates, concurrency requirements, replication features, etc.

The logical design of the database should be centered around data analysis and user requirements; the choice to use a relational database would come later, and even later would the choice of MySQL as a relational database management system, and then the selection of a storage engine for each table.

<%=Html.ActionLink("Contact Us", "ContactUs", "Home", Nothing, New With {.class = "link"})%>

This will assign css class "link" to the Contact Us.

This will generate following HTML :

<a class="link" href="www.domain.com/Home/ContactUs">Contact Us</a>

@RequestMapping(
         value="person", 
         method=RequestMethod.POST,
         consumes="application/json",
         produces="application/json")
@ResponseBody
public List<String> savePerson(@RequestBody Person[] personArray) {
    List<String> response = new ArrayList<String>();
    for (Person person: personArray) {
        personService.save(person);
        response.add("Saved person: " + person.toString());
    }
    return response;
}

We can use Array as shown above.

I assume that you're running a Linux, and you're using gEdit to edit your files. In the /etc/nginx/sites-enabled, it may have left a temp file e.g. default~ (watch the ~).

Depending on your editor, the file could be named .save or something like it. Just run $ ls -lah to see which files are unintended to be there and remove them (Thanks @Tisch for this).

Delete this file, and it will solve your problem.

Reserved.objects.filter(client=client_id).order_by('-check_in')

A hyphen "-" in front of "check_in" indicates descending order. Ascending order is implied.

We don't have to add an all() before filter(). That would still work, but you only need to add all() when you want all objects from the root QuerySet.

More on this here: https://docs.djangoproject.com/en/dev/topics/db/queries/#retrieving-specific-objects-with-filters

Using LEFT JOIN/IS NULL:

DELETE b FROM BLOB b 
  LEFT JOIN FILES f ON f.id = b.fileid 
      WHERE f.id IS NULL

Using NOT EXISTS:

DELETE FROM BLOB 
 WHERE NOT EXISTS(SELECT NULL
                    FROM FILES f
                   WHERE f.id = fileid)

Using NOT IN:

DELETE FROM BLOB
 WHERE fileid NOT IN (SELECT f.id 
                        FROM FILES f)

Warning

Whenever possible, perform DELETEs within a transaction (assuming supported - IE: Not on MyISAM) so you can use rollback to revert changes in case of problems.

I was getting the same problem when running my project. On checking the files structure, I realised that Spring's xml file was inside the project's package and thus couldn't be found. I put it outside the package and it worked just fine.

You can use the library SectionedRecyclerViewAdapter to group your items in sections and add a header to each section, like on the image below:

First you create your section class:

class MySection extends StatelessSection {

    String title;
    List<String> list;

    public MySection(String title, List<String> list) {
        // call constructor with layout resources for this Section header, footer and items 
        super(R.layout.section_header, R.layout.section_item);

        this.title = title;
        this.list = list;
    }

    @Override
    public int getContentItemsTotal() {
        return list.size(); // number of items of this section
    }

    @Override
    public RecyclerView.ViewHolder getItemViewHolder(View view) {
        // return a custom instance of ViewHolder for the items of this section
        return new MyItemViewHolder(view);
    }

    @Override
    public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
        MyItemViewHolder itemHolder = (MyItemViewHolder) holder;

        // bind your view here
        itemHolder.tvItem.setText(list.get(position));
    }

    @Override
    public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
        return new SimpleHeaderViewHolder(view);
    }

    @Override
    public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
        MyHeaderViewHolder headerHolder = (MyHeaderViewHolder) holder;

        // bind your header view here
        headerHolder.tvItem.setText(title);
    }
}

Then you set up the RecyclerView with your sections and change the SpanSize of the headers with a GridLayoutManager:

// Create an instance of SectionedRecyclerViewAdapter 
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();

// Create your sections with the list of data
MySection section1 = new MySection("My Section 1 title", dataList1);
MySection section2 = new MySection("My Section 2 title", dataList2);

// Add your Sections to the adapter
sectionAdapter.addSection(section1);
sectionAdapter.addSection(section2);

// Set up a GridLayoutManager to change the SpanSize of the header
GridLayoutManager glm = new GridLayoutManager(getContext(), 2);
glm.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        switch(sectionAdapter.getSectionItemViewType(position)) {
            case SectionedRecyclerViewAdapter.VIEW_TYPE_HEADER:
                return 2;
            default:
                return 1;
        }
    }
});

// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(glm);
recyclerView.setAdapter(sectionAdapter);

IE11 uses an older version of the Grid specification.

The properties you are using don't exist in the older grid spec. Using prefixes makes no difference.

Here are three problems I see right off the bat.

repeat()

The repeat() function doesn't exist in the older spec, so it isn't supported by IE11.

You need to use the correct syntax, which is covered in another answer to this post, or declare all row and column lengths.

Instead of:

.grid {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: repeat( 4, 1fr );
      grid-template-columns: repeat( 4, 1fr );
  -ms-grid-rows: repeat( 4, 270px );
      grid-template-rows: repeat( 4, 270px );
  grid-gap: 30px;
}

Use:

.grid {
  display: -ms-grid;
  display: grid;
  -ms-grid-columns: 1fr 1fr 1fr 1fr;             /* adjusted */
      grid-template-columns:  repeat( 4, 1fr );
  -ms-grid-rows: 270px 270px 270px 270px;        /* adjusted */
      grid-template-rows: repeat( 4, 270px );
  grid-gap: 30px;
}

Older spec reference: https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#grid-repeating-columns-and-rows

span

The span keyword doesn't exist in the older spec, so it isn't supported by IE11. You'll have to use the equivalent properties for these browsers.

Instead of:

.grid .grid-item.height-2x {
  -ms-grid-row: span 2;
      grid-row: span 2;
}
.grid .grid-item.width-2x {
  -ms-grid-column: span 2;
      grid-column: span 2;
}

Use:

.grid .grid-item.height-2x {
  -ms-grid-row-span: 2;          /* adjusted */
      grid-row: span 2;
}
.grid .grid-item.width-2x {
  -ms-grid-column-span: 2;       /* adjusted */
      grid-column: span 2;
}

Older spec reference: https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#grid-row-span-and-grid-column-span

grid-gap

The grid-gap property, as well as its long-hand forms grid-column-gap and grid-row-gap, don't exist in the older spec, so they aren't supported by IE11. You'll have to find another way to separate the boxes. I haven't read the entire older spec, so there may be a method. Otherwise, try margins.

grid item auto placement

There was some discussion in the old spec about grid item auto placement, but the feature was never implemented in IE11. (Auto placement of grid items is now standard in current browsers).

So unless you specifically define the placement of grid items, they will stack in cell 1,1.

Use the -ms-grid-row and -ms-grid-column properties.

• CSS Grid auto placement in IE/EDGE
• CSS Grid not working in ie11 despite prefixes
• https://www.w3.org/TR/2011/WD-css3-grid-layout-20110407/#automatic-placement-of-grid-items

Don't use CREATE TYPE to return a polymorphic result. Use and abuse the RECORD type instead. Check it out:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Arbitrary expression to change the first parameter
  IF LENGTH(a) < LENGTH(b) THEN
      SELECT TRUE, a || b, 'a shorter than b' INTO ret;
  ELSE
      SELECT FALSE, b || a INTO ret;
  END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Pay attention to the fact that it can optionally return two or three columns depending on the input.

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

test=> SELECT test_ret('barbaz','foo');
             test_ret             
----------------------------------
 (f,foobarbaz)
(1 row)

This does wreak havoc on code, so do use a consistent number of columns, but it's ridiculously handy for returning optional error messages with the first parameter returning the success of the operation. Rewritten using a consistent number of columns:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Note the CASTING being done for the 2nd and 3rd elements of the RECORD
  IF LENGTH(a) < LENGTH(b) THEN
      ret := (TRUE, (a || b)::TEXT, 'a shorter than b'::TEXT);
  ELSE
      ret := (FALSE, (b || a)::TEXT, NULL::TEXT);
   END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Almost to epic hotness:

test=> SELECT test_ret('foobar','bar');
   test_ret    
----------------
 (f,barfoobar,)
(1 row)

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

But how do you split that out in to multiple rows so that your ORM layer of choice can convert the values in to your language of choice's native data types? The hotness:

test=> SELECT a, b, c FROM test_ret('foo','barbaz') AS (a BOOL, b TEXT, c TEXT);
 a |     b     |        c         
---+-----------+------------------
 t | foobarbaz | a shorter than b
(1 row)

test=> SELECT a, b, c FROM test_ret('foobar','bar') AS (a BOOL, b TEXT, c TEXT);
 a |     b     | c 
---+-----------+---
 f | barfoobar | 
(1 row)

This is one of the coolest and most underused features in PostgreSQL. Please spread the word.

You could use createElement() method for creating that textbox

With library fpp, you can easily create time series with date format: time_ser=ts(data,frequency=4,start=c(1954,2))

here we start at the 2nd quarter of 1954 with quarter fequency.

The git command

git count-objects -v

will give you a good estimate of the git repository's size. Without the -v flag, it only tells you the size of your unpacked files. This command may not be in your $PATH, you may have to track it down (on Ubuntu I found it in /usr/lib/git-core/, for instance).

From the Git man-page:

-v, --verbose

In addition to the number of loose objects and disk space consumed, it reports the number of in-pack objects, number of packs, disk space consumed by those packs, and number of objects that can be removed by running git prune-packed.

Your output will look similar to the following:

count: 1910
size: 19764
in-pack: 41814
packs: 3
size-pack: 1066963
prune-packable: 1
garbage: 0

The line you're looking for is size-pack. That is the size of all the packed commit objects, or the smallest possible size for the new cloned repository.

       groundTrump.layer.borderColor = UIColor.red.cgColor

I ran into this problem today. Due to the timeframe and some other issues, getting the key from the provider was not possible.

I found the following solution here (under pixelloa's comment) and thought it would be good to have the answer on Stack Overflow as well.

If the certificate does not have a private key, you can fix this by doing the following:

To fix this, use the MMC snapin to import the cert into PERSONAL store of the computer account, click it and grab the serial # line. Go to dos, run certutil -repairstore my "paste the serial # in here" (you need the quotes unless you remove the spaces from the serial number) then refresh MMC with personal certs, right click it - export - select everything except DELETE PRIVATE KEY, hit ok. Then go to IIS and IMPORT cert instead of finish request.

For what it's worth, all I actually had to do was run the certutil -repairstore command, and my certificate worked. I did run the export and set a password for the export itself, but I did not have to reimport the certificate. The certificate now shows up in IIS's list of certificates and can be used for HTTPS bindings.

I hope this helped someone.

It's very similar to

char array[] = {'O', 'n', 'e', ' ', /*etc*/ ' ', 'm', 'u', 's', 'i', 'c', '\0'};

but gives you read-only memory.

For a discussion of the difference between a char[] and a char *, see comp.lang.c FAQ 1.32.

I got this error in a fresh Rails app with bundle correctly installed. Commenting out the spring gem in Gemfile resolved the problem.

Can you pull some kind of manufacturer serial number or service tag?

Our shop is a Dell shop, so we use the service tag which is unique to each machine to identify them. I know it can be queried from the BIOS, at least in Linux, but I don't know offhand how to do it in Windows.

You will get useful information from here.

SELECT ticker
INTO quotedb
FROM tickerdb;

You want to look into 'Splash' Screens.

Display another 'Splash' form and wait until the processing is done.

Here is an example on how to do it.

The following function searches on multiple patterns, separated by commas. You can also specify an exclusion, eg: "!web.config" will search for all files and exclude "web.config". Patterns can be mixed.

private string[] FindFiles(string directory, string filters, SearchOption searchOption)
{
    if (!Directory.Exists(directory)) return new string[] { };

    var include = (from filter in filters.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries) where !string.IsNullOrEmpty(filter.Trim()) select filter.Trim());
    var exclude = (from filter in include where filter.Contains(@"!") select filter);

    include = include.Except(exclude);

    if (include.Count() == 0) include = new string[] { "*" };

    var rxfilters = from filter in exclude select string.Format("^{0}$", filter.Replace("!", "").Replace(".", @"\.").Replace("*", ".*").Replace("?", "."));
    Regex regex = new Regex(string.Join("|", rxfilters.ToArray()));

    List<Thread> workers = new List<Thread>();
    List<string> files = new List<string>();

    foreach (string filter in include)
    {
        Thread worker = new Thread(
            new ThreadStart(
                delegate
                {
                    string[] allfiles = Directory.GetFiles(directory, filter, searchOption);
                    if (exclude.Count() > 0)
                    {
                        lock (files)
                            files.AddRange(allfiles.Where(p => !regex.Match(p).Success));
                    }
                    else
                    {
                        lock (files)
                            files.AddRange(allfiles);
                    }
                }
            ));

        workers.Add(worker);

        worker.Start();
    }

    foreach (Thread worker in workers)
    {
        worker.Join();
    }

    return files.ToArray();

}

Usage:

foreach (string file in FindFiles(@"D:\628.2.11", @"!*.config, !*.js", SearchOption.AllDirectories))
            {
                Console.WriteLine(file);
            }

MSBuild usually works, but I've run into difficulties before. You may have better luck with

devenv YourSolution.sln /Build 

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

If you already have axes object, just like in Nick T's answer, you can also use

 ax.patch.set_facecolor('black')

It is not planned for IE8. See the CSS Compatibility page.

Beyond that no plans have been released. Rumors exist that IE8 will be the last version for Windows XP

defaultdict can do something like that for you.

Example:

>>> from collections import defaultdict
>>> d = defaultdict(list)
>>> d
defaultdict(<class 'list'>, {})
>>> d['new'].append(10)
>>> d
defaultdict(<class 'list'>, {'new': [10]})

As you mentioned on @Developer 's answer, I would probably HTML-encode on user input. If you are worried about XSS, you probably never need the user's input in it's original form, so you might as well escape it (and replace spaces and newlines while you are at it).

Note that escaping on input means you should either use @Html.Raw or create an MvcHtmlString to render that particular input.

You can also try

System.Security.SecurityElement.Escape(userInput)

but I think it won't escape spaces either. So in that case, I suggest just do a .NET

System.Security.SecurityElement.Escape(userInput).Replace(" ", "&nbsp;").Replace("\n", "<br>")

on user input. And if you want to dig deeper into usability, perhaps you can do an XML parse of the user's input (or play with regular expressions) to only allow a predefined set of tags. For instance, allow

<p>, <span>, <strong>

... but don't allow

<script> or <iframe>

While @Timar's answer works perfectly for null default values (what was asked for), here another easy solution which allows other default values: Define an option interface as well as an according constant containing the defaults; in the constructor use the spread operator to set the options member variable

interface IXOptions {
    a?: string,
    b?: any,
    c?: number
}

const XDefaults: IXOptions = {
    a: "default",
    b: null,
    c: 1
}

export class ClassX {
    private options: IXOptions;

    constructor(XOptions: IXOptions) {
        this.options = { ...XDefaults, ...XOptions };
    }

    public printOptions(): void {
        console.log(this.options.a);
        console.log(this.options.b);
        console.log(this.options.c);
    }
}

Now you can use the class like this:

const x = new ClassX({ a: "set" });
x.printOptions();

Output:

set
null
1

For portability to pre-Bash 3.1 (when the =~ test was introduced), use expr.

if expr "$string" : '-\?[0-9]\+$' >/dev/null
then
  echo "String is a valid integer."
else
  echo "String is not a valid integer."
fi

expr STRING : REGEX searches for REGEX anchored at the start of STRING, echoing the first group (or length of match, if none) and returning success/failure. This is old regex syntax, hence the excess \. -\? means "maybe -", [0-9]\+ means "one or more digits", and $ means "end of string".

Bash also supports extended globs, though I don't recall from which version onwards.

shopt -s extglob
case "$string" of
    @(-|)[0-9]*([0-9]))
        echo "String is a valid integer." ;;
    *)
        echo "String is not a valid integer." ;;
esac

# equivalently, [[ $string = @(-|)[0-9]*([0-9])) ]]

@(-|) means "- or nothing", [0-9] means "digit", and *([0-9]) means "zero or more digits".

Here is an example from my HOW TO Matlab page:

close all; clear all;

img   = imread('lena.tif','tif');
imagesc(img)
img   = fftshift(img(:,:,2));
F     = fft2(img);

figure;

imagesc(100*log(1+abs(fftshift(F)))); colormap(gray); 
title('magnitude spectrum');

figure;
imagesc(angle(F));  colormap(gray);
title('phase spectrum');

This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.

ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say

img = imread('ngc6543a.jpg');

and it will work. I used an older version of Matlab to make the above example and just copied it here.

On the scaling factor

When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c value in the equation

s = c log(1+r) 

There is no known way to pre detrmine this scale that I know. Just need to try different values to get on you like. I used 100 in the above example.

On Windows, just check in the windows task manager if there are any other adb processes running.

Or run adb kill-server

If yes, just kill it & then perform the adb start-server command.

I hope, it should solve the problem.

For higher version of phpunit such as 6.4 You must use the namespace PHPUnit\Framework\TestCase

use TestCase instead PHPUnit_Framework_TestCase

// use the following namespace
use PHPUnit\Framework\TestCase;

// extend using TestCase instead PHPUnit_Framework_TestCase
class SampleTest extends TestCase {

}

OCR can be pretty CPU intensive, you might want to reconsider doing it on a smart phone.

That aside, to my knowledge the popular OCR libraries are Aspire and Tesseract. Neither are straight up Java, so you're not going to get a drop-in Android OCR library.

However, Tesseract is open source (GitHub hosted infact); so you can throw some time at porting the subset you need to Java. My understanding is its not insane C++, so depending on how badly you need OCR it might be worth the time.

So short answer: No.

Long answer: if you're willing to work for it.

Use a slice, like below:

with open('yourfile.txt') as f:
    lines_after_17 = f.readlines()[17:]

If the file is too big to load in memory:

with open('yourfile.txt') as f:
    for _ in range(17):
        next(f)
    for line in f:
        # do stuff

I had the same problem and solved by doing following.

Go to Task Manager, click on services tab, order by pid's than if you find the related process, kill it otherwise, right click and click on show details, the process should be shown now. order by pid's than kill the related process.

Since JSF 2.3 all the bean scopes defined in package javax.faces.bean package have been deprecated to align the scopes with CDI. Moreover they're only applicable if your bean is using @ManagedBean annotation. If you are using JSF versions below 2.3 refer to the legacy answer at the end.

From JSF 2.3 here are scopes that can be used on JSF Backing Beans:

1. @javax.enterprise.context.ApplicationScoped: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. This is useful when you have data for whole application.

2. @javax.enterprise.context.SessionScoped: The session scope persists from the time that a session is established until session termination. The session context is shared between all requests that occur in the same HTTP session. This is useful when you wont to save data for a specific client for a particular session.

3. @javax.enterprise.context.ConversationScoped: The conversation scope persists as log as the bean lives. The scope provides 2 methods: Conversation.begin() and Conversation.end(). These methods should called explicitly, either to start or end the life of a bean.

4. @javax.enterprise.context.RequestScoped: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

5. @javax.faces.flow.FlowScoped: The Flow scope persists as long as the Flow lives. A flow may be defined as a contained set of pages (or views) that define a unit of work. Flow scoped been is active as long as user navigates with in the Flow.

6. @javax.faces.view.ViewScoped: A bean in view scope persists while the same JSF page is redisplayed. As soon as the user navigates to a different page, the bean goes out of scope.

The following legacy answer applies JSF version before 2.3

As of JSF 2.x there are 4 Bean Scopes:

• @SessionScoped
• @RequestScoped
• @ApplicationScoped
• @ViewScoped

Session Scope: The session scope persists from the time that a session is established until session termination. A session terminates if the web application invokes the invalidate method on the HttpSession object, or if it times out.

RequestScope: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

ApplicationScope: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. You place managed beans into the application scope if a single bean should be shared among all instances of a web application. The bean is constructed when it is first requested by any user of the application, and it stays alive until the web application is removed from the application server.

ViewScope: View scope was added in JSF 2.0. A bean in view scope persists while the same JSF page is redisplayed. (The JSF specification uses the term view for a JSF page.) As soon as the user navigates to a different page, the bean goes out of scope.

Choose the scope you based on your requirement.

hai sir

There is one event which is default associate with any webcontrol. For example, in case of Button click event, in case of Check box CheckChangedEvent is there. So in case of AutoPostBack true these events are called by default and event handle at server sid

RESULT:  0.97 %

Android Q broke most of these for me. Here's a new one that seems to be working (at least on Android Q).

adb shell "dumpsys activity activities | grep mResumedActivity"

Output looks like:

mResumedActivity: ActivityRecord{7f6df99 u0 com.sample.app/.feature.SampleActivity t92}

Edit: Works on Android R for me as well

attr_accessor is a Ruby method that makes a getter and a setter. attr_accessible is a Rails method that allows you to pass in values to a mass assignment: new(attrs) or update_attributes(attrs).

Here's a mass assignment:

Order.new({ :type => 'Corn', :quantity => 6 })

You can imagine that the order might also have a discount code, say :price_off. If you don't tag :price_off as attr_accessible you stop malicious code from being able to do like so:

Order.new({ :type => 'Corn', :quantity => 6, :price_off => 30 })

Even if your form doesn't have a field for :price_off, if it's in your model it's available by default. This means a crafted POST could still set it. Using attr_accessible white lists those things that can be mass assigned.

Note that if your variable is continuous, you will have to use geom_histogram(), as the function will group the variable by "bins".

df <- data.frame(V1 = rnorm(100))

ggplot(df, aes(x = V1)) +  
  geom_histogram(aes(y = 100*(..count..)/sum(..count..))) 

# if you use geom_bar(), with factor(V1), each value of V1 will be treated as a
# different category. In this case this does not make sense, as the variable is 
# really continuous. With the hp variable of the mtcars (see previous answer), it 
# worked well since hp was not really continuous (check unique(mtcars$hp)), and one 
# can want to see each value of this variable, and not to group it in bins.
ggplot(df, aes(x = factor(V1))) +  
  geom_bar(aes(y = (..count..)/sum(..count..))) 

I came here looking for a possible explanation before taking a closer look at the lines preceding the linker error. It turned out to have been an additional executable for which the global declaration was missing!

for linux... I use ctrl+pageUp or pageDown

This will take care of the empty td:

<td style="min-width: 20px;"></td>

A working example:

$qb = $this->createQueryBuilder('a');
$query=$qb->getQuery();
// SHOW SQL: 
echo $query->getSQL(); 
// Show Parameters: 
echo $query->getParameters();

If you type this text in your bat file:

start /min blah.exe

It will immediately minimize as soon as it opens the program. You will only see a brief flash of it and it will disappear.

npm updated the CLI command for install and added the --force flag.

npm install --force

The --force (or -f) argument will force npm to fetch remote resources even if a local copy exists on disk.

See npm install

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

Using the RobM special "Remember Property" pattern

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

If you want to escape from Form Freeze and use editing (like text for a button) use this code

Form form = new Form();
Form.Button.Text = "randomText";
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.Run(form);

These answers aren't really addressing the large confusion with between properties and attributes. Also, depending on the Javascript prototype, sometimes you can use a an element's property to access an attributes and sometimes you can't.

First, you have to remember that an HTMLElement is a Javascript object. Like all objects, they have properties. Sure, you can create a property called nearly anything you want inside HTMLElement, but it doesn't have to do anything with the DOM (what's on the page). The dot notation (.) is for properties. Now, there some special properties that are mapped to attributes, and at the time or writing there are only 4 that are guaranteed (more on that later).

All HTMLElements include a property called attributes. HTMLElement.attributes is a live NamedNodeMap Object that relates to the elements in the DOM. "Live" means that when the node changes in the DOM, they change on the JavaScript side, and vice versa. DOM attributes, in this case, are the nodes in question. A Node has a .nodeValue property that you can change. NamedNodeMap objects have a function called setNamedItem where you can change the entire node. You can also directly access the node by the key. For example, you can say .attributes["dir"] which is the same as .attributes.getNamedItem('dir'); (Side note, NamedNodeMap is case-insensitive, so you can also pass 'DIR');

There's a similar function directly in HTMLElement where you can just call setAttribute which will automatically create a node if it doesn't exist and set the nodeValue. There are also some attributes you can access directly as properties in HTMLElement via special properties, such as dir. Here's a rough mapping of what it looks like:

HTMLElement {
  attributes: {
    setNamedItem: function(attr, newAttr) { 
      this[attr] = newAttr;
    },    
    getNamedItem: function(attr) {
      return this[attr];
    },
    myAttribute1: {
      nodeName: 'myAttribute1',
      nodeValue: 'myNodeValue1'
    },
    myAttribute2: {
      nodeName: 'myAttribute2',
      nodeValue: 'myNodeValue2'
    },
  }
  setAttribute: function(attr, value) { 
    let item = this.attributes.getNamedItem(attr);
    if (!item) {
      item = document.createAttribute(attr);
      this.attributes.setNamedItem(attr, item);
    }
    item.nodeValue = value;
  },
  getAttribute: function(attr) { 
    return this.attributes[attr] && this.attributes[attr].nodeValue;
  },
  dir: // Special map to attributes.dir.nodeValue || ''
  id:  // Special map to attributes.id.nodeValue || ''
  className: // Special map to attributes.class.nodeValue || '' 
  lang: // Special map to attributes.lang.nodeValue || ''

}

So you can change the dir attributes 6 ways:

  // 1. Replace the node with setNamedItem
  const newAttribute = document.createAttribute('dir');
  newAttribute.nodeValue = 'rtl';
  element.attributes.setNamedItem(newAttribute);

  // 2. Replace the node by property name;
  const newAttribute2 = document.createAttribute('dir');
  newAttribute2.nodeValue = 'rtl';
  element.attributes['dir'] = newAttribute2;
  // OR
  element.attributes.dir = newAttribute2;

  // 3. Access node with getNamedItem and update nodeValue
  // Attribute must already exist!!!
  element.attributes.getNamedItem('dir').nodeValue = 'rtl';

  // 4. Access node by property update nodeValue
  // Attribute must already exist!!!
  element.attributes['dir'].nodeValue = 'rtl';
  // OR
  element.attributes.dir.nodeValue = 'rtl';

  // 5. use setAttribute()  
  element.setAttribute('dir', 'rtl');
  
  // 6. use the UNIQUELY SPECIAL dir property
  element["dir"] = 'rtl';
  element.dir = 'rtl';

You can update all properties with methods #1-5, but only dir, id, lang, and className with method #6.

Extensions of HTMLElement

HTMLElement has those 4 special properties. Some elements are extended classes of HTMLElement have even more mapped properties. For example, HTMLAnchorElement has HTMLAnchorElement.href, HTMLAnchorElement.rel, and HTMLAnchorElement.target. But, beware, if you set those properties on elements that do not have those special properties (like on a HTMLTableElement) then the attributes aren't changed and they are just, normal custom properties. To better understand, here's an example of its inheritance:

HTMLAnchorElement extends HTMLElement {
  // inherits all of HTMLElement
  href:    // Special map to attributes.href.nodeValue || ''
  target:  // Special map to attributes.target.nodeValue || ''
  rel:     // Special map to attributes.ref.nodeValue || '' 
}

Custom Properties

Now the big warning: Like all Javascript objects, you can add custom properties. But, those won't change anything on the DOM. You can do:

  const newElement = document.createElement('div');
  // THIS WILL NOT CHANGE THE ATTRIBUTE
  newElement.display = 'block';

But that's the same as

  newElement.myCustomDisplayAttribute = 'block';

This means that adding a custom property will not be linked to .attributes[attr].nodeValue.

Performance

I've built a jsperf test case to show the difference: https://jsperf.com/set-attribute-comparison. Basically, In order:

1. Custom properties because they don't affect the DOM and are not attributes.
2. Special mappings provided by the browser (dir, id, className).
3. If attributes already exists, element.attributes.ATTRIBUTENAME.nodeValue =
4. setAttribute();
5. If attributes already exists, element.attributes.getNamedItem(ATTRIBUTENAME).nodeValue = newValue
6. element.attributes.ATTRIBUTENAME = newNode
7. element.attributes.setNamedItem(ATTRIBUTENAME) = newNode

Conclusion (TL;DR)

• Use the special property mappings from HTMLElement: element.dir, element.id, element.className, or element.lang.

• If you are 100% sure the element is an extended HTMLElement with a special property, use that special mapping. (You can check with if (element instanceof HTMLAnchorElement)).

• If you are 100% sure the attribute already exists, use element.attributes.ATTRIBUTENAME.nodeValue = newValue.

• If not, use setAttribute().

After a brief review of the YAML cookbook cited in the question and some testing, here's my interpretation:

• In general, you don't need quotes.
• Use quotes to force a string, e.g. if your key or value is 10 but you want it to return a String and not a Fixnum, write '10' or "10".
• Use quotes if your value includes special characters, (e.g. :, {, }, [, ], ,, &, *, #, ?, |, -, <, >, =, !, %, @, \).
• Single quotes let you put almost any character in your string, and won't try to parse escape codes. '\n' would be returned as the string \n.
• Double quotes parse escape codes. "\n" would be returned as a line feed character.
• The exclamation mark introduces a method, e.g. !ruby/sym to return a Ruby symbol.

Seems to me that the best approach would be to not use quotes unless you have to, and then to use single quotes unless you specifically want to process escape codes.

Update

"Yes" and "No" should be enclosed in quotes (single or double) or else they will be interpreted as TrueClass and FalseClass values:

en:
  yesno:
    'yes': 'Yes'
    'no': 'No'

I 've been using ctrl + d. It throws you out into the destination where You've started the sqlite3 command in the first place.

You can use the parse_url() and parse_str() for that.

$parts = parse_url($url);
parse_str($parts['query'], $query);
echo $query['email'];

If you want to get the $url dynamically with PHP, take a look at this question:

You need a dependency property for this:

public BindingList<User> Users
{
    get { return (BindingList<User>)GetValue(UsersProperty); }
    set { SetValue(UsersProperty, value); }
}

public static readonly DependencyProperty UsersProperty =
    DependencyProperty.Register("Users", typeof(BindingList<User>), 
      typeof(OptionsDialog));

Once that is done, you bind the checkbox to the dependency property:

<CheckBox x:Name="myCheckBox"
          IsChecked="{Binding ElementName=window1, Path=CheckBoxIsChecked}" />

For that to work you have to name your Window or UserControl in its openning tag, and use that name in the ElementName parameter.

With this code, whenever you change the property on the code side, you will change the textbox. Also, whenever you check/uncheck the textbox, the Dependency Property will change too.

EDIT:

An easy way to create a dependency property is typing the snippet propdp, which will give you the general code for Dependency Properties.

All the code:

XAML:

<Window x:Class="StackOverflowTests.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" x:Name="window1" Height="300" Width="300">
    <Grid>
        <StackPanel Orientation="Vertical">
            <CheckBox Margin="10"
                      x:Name="myCheckBox"
                      IsChecked="{Binding ElementName=window1, Path=IsCheckBoxChecked}">
                Bound CheckBox
            </CheckBox>
            <Label Content="{Binding ElementName=window1, Path=IsCheckBoxChecked}"
                   ContentStringFormat="Is checkbox checked? {0}" />
        </StackPanel>
    </Grid>
</Window>

C#:

using System.Windows;

namespace StackOverflowTests
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public bool IsCheckBoxChecked
        {
           get { return (bool)GetValue(IsCheckBoxCheckedProperty); }
           set { SetValue(IsCheckBoxCheckedProperty, value); }
        }

        // Using a DependencyProperty as the backing store for 
         //IsCheckBoxChecked.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty IsCheckBoxCheckedProperty =
            DependencyProperty.Register("IsCheckBoxChecked", typeof(bool), 
            typeof(Window1), new UIPropertyMetadata(false));

        public Window1()
        {             
            InitializeComponent();
        }
    }
}

Notice how the only code behind is the Dependency Property. Both the label and the checkbox are bound to it. If the checkbox changes, the label changes too.

I've seen many answers with many votes advocating using the ternary operator. The ternary is great if a) you do have an alternative option and b) you are returning a fairly simple value from a simple condition. But...

The original question didn't have an alternative, and the ternary operator with only a single (real) branch forces you to return a confected answer.

lemons ? "foo gave me a bar" : "who knows what you'll get back"

I think the most common variation is lemons ? 'foo...' : '', and, as you'll know from reading the myriad of articles for any language on true, false, truthy, falsey, null, nil, blank, empty (with our without ?) , you are entering a minefield (albeit a well documented minefield.)

As soon as any part of the ternary gets complicated you are better off with a more explicit form of conditional.

A long way to say that I am voting for if (lemons) "foo".

You can seek until the end, then compute the difference:

std::streampos fileSize( const char* filePath ){

    std::streampos fsize = 0;
    std::ifstream file( filePath, std::ios::binary );

    fsize = file.tellg();
    file.seekg( 0, std::ios::end );
    fsize = file.tellg() - fsize;
    file.close();

    return fsize;
}

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

The below code will call a function while the script is done loading

I have used the using Newtonsoft.Json as below. Create an object:

 public class WorklistSortColumn
  {
    [JsonProperty(PropertyName = "field")]
    public string Field { get; set; }

    [JsonProperty(PropertyName = "dir")]
    public string Direction { get; set; }

    [JsonIgnore]
    public string SortOrder { get; set; }
  }

Now Call the below method to serialize to Json object as shown below.

string sortColumn = JsonConvert.SerializeObject(worklistSortColumn);

Yes there is a static nested class in java. When you declare a nested class static, it automatically becomes a stand alone class which can be instantiated without having to instantiate the outer class it belongs to.

Example:

public class A
{

 public static class B
 {
 }
}

Because class B is declared static you can explicitly instantiate as:

B b = new B();

Note if class B wasn't declared static to make it stand alone, an instance object call would've looked like this:

A a= new A();
B b = a.new B();

Unfortunately none of the solutions works for me.

1. If you don't set pressed state at first it won't detect it.
2. If you set it, then you need to define empty state to add default color

ColorStateList themeColorStateList = new ColorStateList(
        new int[][]{
                new int[]{android.R.attr.state_pressed},
                new int[]{android.R.attr.state_enabled},
                new int[]{android.R.attr.state_focused, android.R.attr.state_pressed},
                new int[]{-android.R.attr.state_enabled},
                new int[]{} // this should be empty to make default color as we want
        },
        new int[]{
                pressedFontColor,
                defaultFontColor,
                pressedFontColor,
                disabledFontColor,
                defaultFontColor
        }
);

This is constructor from source code:

/**
 * Creates a ColorStateList that returns the specified mapping from
 * states to colors.
 */
public ColorStateList(int[][] states, int[] colors) {
    mStateSpecs = states;
    mColors = colors;

    if (states.length > 0) {
        mDefaultColor = colors[0];

        for (int i = 0; i < states.length; i++) {
            if (states[i].length == 0) {
                mDefaultColor = colors[i];
            }
        }
    }
}

After creating the DB link, if the two instances are present in two different databases, then you need to setup a TNS entry on the A machine so that it resolve B. check out here

In my case, I needed to close just one excel window and not the entire application, so, I needed to tell which exact window to close, without saving it.

The following lines work just fine:

Sub test_t()
  Windows("yourfilename.xlsx").Activate
  ActiveWorkbook.Close SaveChanges:=False
End Sub

From the first link on google;

function call_func(_0x41dcx2) {
 var _0x41dcx3 = eval('(' + _0x41dcx2 + ')');
 var _0x41dcx4 = document['createElement']('div');
 var _0x41dcx5 = _0x41dcx3['id'];
 var _0x41dcx6 = _0x41dcx3['Student_name'];
 var _0x41dcx7 = _0x41dcx3['student_dob'];
 var _0x41dcx8 = '<b>ID:</b>';
 _0x41dcx8 += '<a href="/learningyii/index.php?r=student/view&amp; id=' + _0x41dcx5 + '">' + _0x41dcx5 + '</a>';
 _0x41dcx8 += '<br/>';
 _0x41dcx8 += '<b>Student Name:</b>';
 _0x41dcx8 += _0x41dcx6;
 _0x41dcx8 += '<br/>';
 _0x41dcx8 += '<b>Student DOB:</b>';
 _0x41dcx8 += _0x41dcx7;
 _0x41dcx8 += '<br/>';
 _0x41dcx4['innerHTML'] = _0x41dcx8;
 _0x41dcx4['setAttribute']('class', 'view');
 $('#StudentGridViewId')['find']('.items')['prepend'](_0x41dcx4);
};

It won't get you all the way back to source, and that's not really possible, but it'll get you out of a hole.

Any ideas on how to parse "2010-08-17 12:09:36" with new Date()?

Until ES5, there was no string format that browsers were required to support, though there are a number that are widely supported. However browser support is unreliable an inconsistent, e.g. some will allow out of bounds values and others wont, some support certain formats and others don't, etc.

ES5 introduced support for some ISO 8601 formats, however the OP is not compliant with ISO 8601 and not all browsers in use support it anyway.

The only reliable way is to use a small parsing function. The following parses the format in the OP and also validates the values.

/* Parse date string in format yyyy-mm-dd hh:mm:ss_x000D_
** If string contains out of bounds values, an invalid date is returned_x000D_
** _x000D_
** @param {string} s - string to parse, e.g. "2010-08-17 12:09:36"_x000D_
**                     treated as "local" date and time_x000D_
** @returns {Date}   - Date instance created from parsed string_x000D_
*/_x000D_
function parseDateString(s) {_x000D_
  var b = s.split(/\D/);_x000D_
  var d = new Date(b[0], --b[1], b[2], b[3], b[4], b[5]);_x000D_
  return d && d.getMonth() == b[1] && d.getHours() == b[3] &&_x000D_
         d.getMinutes() == b[4]? d : new Date(NaN);_x000D_
}_x000D_
  _x000D_
document.write(_x000D_
  parseDateString('2010-08-17 12:09:36') + '<br>' +  // Valid values_x000D_
  parseDateString('2010-08-45 12:09:36')             // Out of bounds date_x000D_
);

I got this issue when i wrote :
export default connect (mapDispatchToProps,mapStateToProps)(SearchInsectsComponent); instead of export default connect (mapStateToProps,mapDispatchToProps)(SearchInsectsComponent);

We can do it nicely using Interceptors. You dont have to set options in all your services neither manage all your error responses, just define 2 interceptors (one to do something before sending the request to server and one to do something before sending the server's response to your service)

1. Define an AuthInterceptor class to do something before sending the request to the server. You can set the api token (retrieve it from localStorage, see step 4) and other options in this class.
2. Define an responseInterceptor class to do something before sending the server response to your service (httpClient). You can manage your server response, the most comon use is to check if the user's token is valid (if not clear token from localStorage and redirect to login).

3. In your app.module import HTTP_INTERCEPTORS from '@angular/common/http'. Then add to your providers the interceptors (AuthInterceptor and responseInterceptor). Doing this your app will consider the interceptors in all our httpClient calls.

4. At login http response (use http service), save the token at localStorage.

5. Then use httpClient for all your apirest services.

You can check some good practices on my github proyect here

driver.page_source will help you get the page source code. You can check if the text is present in the page source or not.

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("some url")
if "your text here" in driver.page_source:
    print('Found it!')
else:
    print('Did not find it.')

If you want to store the page source in a variable, add below line after driver.get:

var_pgsource=driver.page_source

and change the if condition to:

if "your text here" in var_pgsource:

I think that the RoundingMode you are looking for is ROUND_HALF_EVEN. From the javadoc:

Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for ROUND_HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for ROUND_HALF_DOWN if it's even. Note that this is the rounding mode that minimizes cumulative error when applied repeatedly over a sequence of calculations.

Here is a quick test case:

BigDecimal a = new BigDecimal("10.12345");
BigDecimal b = new BigDecimal("10.12556");

a = a.setScale(2, BigDecimal.ROUND_HALF_EVEN);
b = b.setScale(2, BigDecimal.ROUND_HALF_EVEN);

System.out.println(a);
System.out.println(b);

Correctly prints:

10.12
10.13

UPDATE:

setScale(int, int) has not been recommended since Java 1.5, when enums were first introduced, and was finally deprecated in Java 9. You should now use setScale(int, RoundingMode) e.g:

setScale(2, RoundingMode.HALF_EVEN)

One more possibility. AWS security groups are setup to work only with specific incoming ip addresses. If your security group is setup in this way you (or the account holder) will need to add your ip address to the security group. Todo this open your AWS dashboard, select security groups, select a security group and click on the inbound tab. Then add your ip as appropriate.

For Kotlin use KTX extension function: (It uses TextWatcher as previous answers)

I don't know if homework counts...

During my studies we rolled our own program to solve the Traveling Salesman problem.

The idea was to make a comparison on several criteria (difficulty to map the problem, performance, etc) and we also used other techniques such as Simulated annealing.

It worked pretty well, but it took us a while to understand how to do the 'reproduction' phase correctly: modeling the problem at hand into something suitable for Genetic programming really struck me as the hardest part...

It was an interesting course since we also dabbled with neural networks and the like.

I'd like to know if anyone used this kind of programming in 'production' code.

The main difference between querySelector and getlementbyID(Claassname,Tagname etc) is if there is more than one elements which satifies the condition querySelector will return only one output whereas getElementBy* will return all the elements.

Lets consider an example to make it more clear.

 <nav id="primary" class="menu">
                            <a class="link" href="#">For Business</a>
                            <a class="link" href="#">Become an Instructor</a>
                            <a class="link" href="#">Mobile Applications</a>
                            <a class="link" href="#">Support</a>
                            <a class="link" href="#">Help</a>
   </nav> 

Below code will explain the difference

**QUERY SELECTOR**
document.querySelector('.link'); // Output : For Business (element)

document.querySelectorAll('.link'); //Out All the element with class link

**GET ELEMENT**
document.getElementsByClassName('link') // Output : will return all the element with a class "link" but whereas in query selector it will return only one element which encounters first.

Inshort if we want to select single element go for queryslector or if we want multiple element go for getElement

FileInputStream input = new FileInputStream(file);

I got the answer for the same , Go on SQL Server ? Tools ? Options ? Designers ? Table and Database Designers and unselect Prevent saving changes that require table re-creation

2- Open table design view and that scroll your column up and down and save your changes.

When the user taps the Done button on the text keyboard, a Did End On Exit event will be generated; at that time, we need to tell the text field to give up control so that the keyboard will go away. In order to do that, we need to add an action method to our controller class. Select ViewController.swift add the following action method:

@IBAction func textFieldDoneEditing(sender: UITextField) {
sender.resignFirstResponder()}

Select Main.storyboard in the Project Navigator and bring up the connections inspector. Drag from the circle next to Did End On Exit to the yellow View Controller icon in the storyboard and let go. A small pop-up menu will appear containing the name of a single action, the one we just added. Click the textFieldDoneEditing action to select it and that's it.

For python 3, you can use bool()

>>> bool(None)
False
>>> bool("")
False
>>> bool("a")
True
>>> bool("ab")
True
>>> bool("9")
True

A good way of going about this is not to use nargin, but to check whether the variables have been set using exist('opt', 'var').

Example:

function [a] = train(x, y, opt)
    if (~exist('opt', 'var'))
        opt = true;
    end
end

See this answer for pros of doing it this way: How to check whether an argument is supplied in function call?

You want your if check to be:

{% if not loop.last %}
    ,
{% endif %}

Note that you can also shorten the code by using If Expression:

{{ ", " if not loop.last else "" }}

Although probably not exactly what your looking for and you probably don't care at this point since the question was asked 5 years ago, one method is to use "forward".

Go to your inbox or wherever your messages are and select the 2+ messages you want to send than simply click forward... all messages get combined into 1.

For ruby 1.8.7 you could add the following to your code:

class Float
    alias oldround:round
    def round(precision = nil)
        if precision.nil?
            return self
        else
            return ((self * 10**precision).oldround.to_f) / (10**precision)
        end 
    end 
end

You need to append your variables to the echoed string. For example:

echo 'This is a string '.$PHPvariable.' and this is more string'; 

maybe some addition for avoid fakepath:

var fileName = $('input[type=file]').val();
var clean=fileName.split('\\').pop(); // clean from C:\fakepath OR C:\fake_path 
alert('clean file name : '+ fileName);

Try this:

a = np.matrix([[1,2], [3,4]])
b = np.matrix([[5,6], [7,8]])

#This would result a 'numpy.ndarray'
result = np.array(a) * np.array(b)

Here, np.array(a) returns a 2D array of type ndarray and multiplication of two ndarray would result element wise multiplication. So the result would be:

result = [[5, 12], [21, 32]]

If you wanna get a matrix, the do it with this:

result = np.mat(result)

This is the full thing

binary = input('enter a number: ')
decimal = 0
for digit in binary:
decimal= decimal*2 + int(digit)

print (decimal)

I came up with 2 quick solutions. Either work for me. I think the problem is because of permissions.

1) Instead of using the Elmah.dll file from the net-2.0 directory, I used Elmah.dll from net-1.1 .

2) Instead of keeping Elmah.dll in the project bin directory. I make a dll directory to put it in.

No need to use the command line.

If you FILE-> "Export Android Application" in the ADK then it will allow you to create a key and then produce your .apk file.

Use std::stringstream. Its operator << is overloaded for all built-in types.

#include <sstream>    

std::stringstream s;
s << "(" << c1 << "," << c2 << ")";
storedCorrect[count] = s.str();

This works like you'd expect - the same way you print to the screen with std::cout. You're simply "printing" to a string instead. The internals of operator << take care of making sure there's enough space and doing any necessary conversions (e.g., double to string).

Also, if you have the Boost library available, you might consider looking into lexical_cast. The syntax looks much like the normal C++-style casts:

#include <string>
#include <boost/lexical_cast.hpp>
using namespace boost;

storedCorrect[count] = "(" + lexical_cast<std::string>(c1) +
                       "," + lexical_cast<std::string>(c2) + ")";

Under the hood, boost::lexical_cast is basically doing the same thing we did with std::stringstream. A key advantage to using the Boost library is you can go the other way (e.g., string to double) just as easily. No more messing with atof() or strtod() and raw C-style strings.

If it is "pretty large" file, then access the lines sequentially and don't read the whole file into memory:

with open('largeFile', 'r') as inF:
    for line in inF:
        if 'myString' in line:
            # do_something

I had a similar problem with HTML input fields in MVC. The web paged only showed the first keyword of the field. Example: input field: "The quick brown fox" Displayed value: "The"

The resolution was to put the variable in quotes in the value statement as follows:

<input class="ParmInput" type="text" id="respondingRangerUnit" name="respondingRangerUnit"
       onchange="validateInteger(this.value)" value="@ViewBag.respondingRangerUnit">

After using git for a long time without problems, I encountered this problem today. After some reflection, I realized I changed my umask earlier today from 022 to something else.

All the answers by other people are helpful, i.e., do chmod for the offending directories. But the root cause is my new umask which will always cause a new problem down the road whenever a new directory is created under .git/object/. So, the long term solution for me is to change umask back to 022.

git stash list to list your stashed changes.

git stash show to see what n is in the below commands.

Why noy just use the theme styles in the table? i.e.

<table>
  <thead class="ui-widget-header">
    <tr>
      <th>Id</th>
      <th>Description</th>
    </td>
  </thead>
  <tbody class="ui-widget-content">
    <tr>
      <td>...</td>
      <td>...</td>
    </tr>
      .
      .
      .
  </tbody>
</table>

While creating OkHttpClient that will be used for Retrofit.

add an Interceptor like this.

 private val httpClient = OkHttpClient.Builder()
        .addInterceptor (other interceptors)
        ........................................

        //This Interceptor is the main logging Interceptor
        .addInterceptor { chain ->
            val request = chain.request()
            val jsonObj = JSONObject(Gson().toJson(request))

            val requestBody = (jsonObj
            ?.getJSONObject("tags")
            ?.getJSONObject("class retrofit2.Invocation")
            ?.getJSONArray("arguments")?.get(0) ?: "").toString()
            val url = jsonObj?.getJSONObject("url")?.getString("url") ?: ""
            
            Timber.d("gsonrequest request url: $url")
            Timber.d("gsonrequest body :$requestBody")

            chain.proceed(request)
        }
        
        ..............
        // Add other configurations
        .build()

Now your every Retrofit call's URL and request body will be logged in Logcat. Filter it by "gsonrequest"

There isn't a 1-1 correspondence between IPv4 and IPv6 addresses (nor between IP addresses and devices), so what you're asking for generally isn't possible.

There is a particular range of IPv6 addresses that actually represent the IPv4 address space, but general IPv6 addresses will not be from this range.

If you just wanted to change the example and put the table at the top, then loc='top' in the table declaration is what you need,

the_table = ax.table(cellText=cell_text,
                      rowLabels=rows,
                      rowColours=colors,
                      colLabels=columns,
                      loc='top')

Then adjusting the plot with,

plt.subplots_adjust(left=0.2, top=0.8)

A more flexible option is to put the table in its own axis using subplots,

import numpy as np
import matplotlib.pyplot as plt


fig, axs =plt.subplots(2,1)
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs[0].axis('tight')
axs[0].axis('off')
the_table = axs[0].table(cellText=clust_data,colLabels=collabel,loc='center')

axs[1].plot(clust_data[:,0],clust_data[:,1])
plt.show()

which looks like this,

You are then free to adjust the locations of the axis as required.

Use ';' as the separator. If your environment variables are set correctly, you should see your settings. If your PATH and CLASSPATH is correct, windows should recognize those commands. You do NOT need to restart your computer when installing Java.

Option 2:

you can change your SQL Management Studio Options like

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

The first way
Needs root

Use kill:

adb shell ps => Will list all running processes on the device and their process ids
adb shell kill <PID> => Instead of <PID> use process id of your application

The second way
In Eclipse open DDMS perspective.
In Devices view you will find all running processes.
Choose the process and click on Stop.

The third way
It will kill only background process of an application.

adb shell am kill [options] <PACKAGE> => Kill all processes associated with (the app's package name). This command kills only processes that are safe to kill and that will not impact the user experience.
Options are:

--user | all | current: Specify user whose processes to kill; all users if not specified.

The fourth way
Needs root

adb shell pm disable <PACKAGE> => Disable the given package or component (written as "package/class").

The fifth way
Note that run-as is only supported for apps that are signed with debug keys.

run-as <package-name> kill <pid>

The sixth way
Introduced in Honeycomb

adb shell am force-stop <PACKAGE> => Force stop everything associated with (the app's package name).

P.S.: I know that the sixth method didn't work for you, but I think that it's important to add this method to the list, so everyone will know it.

itertools.combinations is in general the fastest way to get combinations from a Python container (if you do in fact want combinations, i.e., arrangements WITHOUT repetitions and independent of order; that's not what your code appears to be doing, but I can't tell whether that's because your code is buggy or because you're using the wrong terminology).

If you want something different than combinations perhaps other iterators in itertools, product or permutations, might serve you better. For example, it looks like your code is roughly the same as:

for val in itertools.product(np.arange(0, 1, 0.1), repeat=6):
    print F(val)

All of these iterators yield tuples, not lists or numpy arrays, so if your F is picky about getting specifically a numpy array you'll have to accept the extra overhead of constructing or clearing and re-filling one at each step.

Go Playground

My home-grown regular expression replace function can be used for this.

Demo

See this DB-Fiddle demo, which returns the second word ("I") from a famous sonnet and the number of occurrences of it (1).

SQL

Assuming MySQL 8 or later is being used (to allow use of a Common Table Expression), the following will return the second word and the number of occurrences of it:

WITH cte AS (
     SELECT digits.idx,
            SUBSTRING_INDEX(SUBSTRING_INDEX(words, '~', digits.idx + 1), '~', -1) word
     FROM
     (SELECT reg_replace(UPPER(txt),
                         '[^''’a-zA-Z-]+',
                         '~',
                         TRUE,
                         1,
                         0) AS words
      FROM tbl) delimited
     INNER JOIN
     (SELECT @row := @row + 1 as idx FROM 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t1,

      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t3, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t4, 
      (SELECT @row := -1) t5) digits
     ON LENGTH(REPLACE(words, '~' , '')) <= LENGTH(words) - digits.idx)
SELECT c.word,
       subq.occurrences
FROM cte c
LEFT JOIN (
  SELECT word,
         COUNT(*) AS occurrences
  FROM cte
  GROUP BY word
) subq
ON c.word = subq.word
WHERE idx = 1; /* idx is zero-based so 1 here gets the second word */

Explanation

A few tricks are used in the SQL above and some accreditation is needed. Firstly the regular expression replacer is used to replace all continuous blocks of non-word characters - each being replaced by a single tilda (~) character. Note: A different character could be chosen instead if there is any possibility of a tilda appearing in the text.

The technique from this answer is then used for transforming a string with delimited values into separate row values. It's combined with the clever technique from this answer for generating a table consisting of a sequence of incrementing numbers: 0 - 10,000 in this case.

Oracle SQL Developer

This code works for me:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Script.Serialization;

namespace Json
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(DeserializeNames());
            Console.ReadLine();
        }

        public static string DeserializeNames()
        {
            var jsonData = "{\"name\":[{\"last\":\"Smith\"},{\"last\":\"Doe\"}]}";

            JavaScriptSerializer ser = new JavaScriptSerializer();

            nameList myNames = ser.Deserialize<nameList>(jsonData);

            return ser.Serialize(myNames);
        }

        //Class descriptions

        public class name
        {
            public string last { get; set; }
        }

        public class nameList
        {
            public List<name> name { get; set; }
        }
    }
}

You can throw your own custom errors by extending the Exception class.

class CustomException : Exception {
    [string] $additionalData

    CustomException($Message, $additionalData) : base($Message) {
        $this.additionalData = $additionalData
    }
}

try {
    throw [CustomException]::new('Error message', 'Extra data')
} catch [CustomException] {
    # NOTE: To access your custom exception you must use $_.Exception
    Write-Output $_.Exception.additionalData

    # This will produce the error message: Didn't catch it the second time
    throw [CustomException]::new("Didn't catch it the second time", 'Extra data')
}

I agree with @haha on this one, for the most part. But there are several cross-browser related issues with using the "float:right" and could ultimately give you more of a headache than you want. If you know what the widths are going to be for each column use a float:left on both and save yourself the trouble. Another thing you can incorporate into your methodology is build column classes into your CSS.

So try something like this:

CSS

.col-wrapper{width:960px; margin:0 auto;}
.col{margin:0 10px; float:left; display:inline;}
.col-670{width:670px;}
.col-250{width:250px;}

HTML

<div class="col-wrapper">
    <div class="col col-670">[Page Content]</div>
    <div class="col col-250">[Page Sidebar]</div>
</div>

Test here with JSFIDDLE - Paste directly from Microsoft Excel to get table

Well, you can do

DataTable data = (DataTable)(dgvMyMembers.DataSource);

and then use

data.Columns.Remove(...);

I think it's the fastest way. This will modify data source table, if you don't want it, then copy of table is reqired. Also be aware that DataGridView.DataSource is not necessarily of DataTable type.

C# 6.0 adds readonly auto properties

public object MyProperty { get; }

So when you don't need to support older compilers you can have a truly readonly property with code that's just as concise as a readonly field.

Versioning:
I think it doesn't make much difference if you are only interested in source compatibility.
Using a property is better for binary compatibility since you can replace it by a property which has a setter without breaking compiled code depending on your library.

Convention:
You are following the convention. In cases like this where the differences between the two possibilities are relatively minor following the convention is better. One case where it might come back to bite you is reflection based code. It might only accept properties and not fields, for example a property editor/viewer.

Serialization
Changing from field to property will probably break a lot of serializers. And AFAIK XmlSerializer does only serialize public properties and not public fields.

Using an Autoproperty
Another common Variation is using an autoproperty with a private setter. While this is short and a property it doesn't enforce the readonlyness. So I prefer the other ones.

Readonly field is selfdocumenting
There is one advantage of the field though:
It makes it clear at a glance at the public interface that it's actually immutable (barring reflection). Whereas in case of a property you can only see that you cannot change it, so you'd have to refer to the documentation or implementation.

But to be honest I use the first one quite often in application code since I'm lazy. In libraries I'm typically more thorough and follow the convention.

If you need to resume an scp transfer from local to remote, try with rsync:

rsync --partial --progress --rsh=ssh local_file user@host:remote_file

Short version, as pointed out by @aurelijus-rozenas:

rsync -P -e ssh local_file user@host:remote_file

In general the order of args for rsync is

rsync [options] SRC DEST

Since this questions seems to still get quite a lot of views, it might be useful to note that for Spring 4+ it's easiest to start using Spring Boot and the Spring Boot starter POMs.

Using Spring Boot there's less dependencies to manage (and thus fewer conflicts), and setting up a working, well integrated Spring Context is a whole lot easier. I highly recommend it.

This is how I do it if I need a form displayed for each item, and inputs for various properties. Really depends on what I'm trying to do though.

ViewModel looks like this:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

View(with BeginForm of course):

@model MyViewModel


@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

Action:

[HttpPost]public ViewResult(MyViewModel vm)
{
...

Note that on post back only properties which had inputs available will have values. I.e., if Person had a .SSN property, it would not be available in the post action because it wasn't a field in the form.

Note that the way MVC's model binding works, it will only look for consecutive ID's. So doing something like this where you conditionally hide an item will cause it to not bind any data after the 5th item, because once it encounters a gap in the IDs, it will stop binding. Even if there were 10 people, you would only get the first 4 on the postback:

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    if(i != 4)//conditionally hide 5th item, 
    { //but BUG occurs on postback, all items after 5th will not be bound to the the list
      @Html.HiddenFor(m => m.Persons[i].PersonId)
      @Html.EditorFor(m => m.Persons[i].FirstName) 
      @Html.EditorFor(m => m.Persons[i].LastName)           
    }
}

A COUNT query is faster, although maybe not noticeably, but as far as getting the desired result, both should be sufficient.

From Bootstrap's docs about the remote option;

This option is deprecated since v3.3.0 and has been removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

That's the .modal-content div, not .modal-body. If you want to put content inside .modal-body then you need to do that with custom javascript.

So I would call jQuery.load programmatically, meaning you can keep the functionality of the dismiss and/or other buttons as required.

To do this you could use a data tag with the URL from the button that opens the modal, and use the show.bs.modal event to load content into the .modal-body div.

HTML Link/Button

<a href="#" data-toggle="modal" data-load-url="remote.html" data-target="#myModal">Click me</a>

jQuery

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = $(e.relatedTarget).data('load-url');
    $(this).find('.modal-body').load(loadurl);
});

You are most likely pushing a string 'NULL' to the table, rather then an actual NULL, but other things may be going on as well, an illustration:

mysql> CREATE TABLE date_test (pdd DATE NOT NULL);
Query OK, 0 rows affected (0.11 sec)

mysql> INSERT INTO date_test VALUES (NULL);
ERROR 1048 (23000): Column 'pdd' cannot be null
mysql> INSERT INTO date_test VALUES ('NULL');
Query OK, 1 row affected, 1 warning (0.05 sec)

@AlexK wrote a great answer. I just want to add my two cents. The code below is entirely based on @AlexK's answer, the difference is that you can specify the user and a time since the last batch was executed (note that the code uses sys.dm_exec_sessions instead of master..sysprocess):

DECLARE @kill varchar(8000);
set @kill =''
select @kill = @kill + 'kill ' +  CONVERT(varchar(5), session_id) + ';' from sys.dm_exec_sessions 
where login_name = 'usrDBTest'
and datediff(hh,login_time,getdate()) > 1
--and session_id in (311,266)    
exec(@kill)

In this example only the process of the user usrDBTest which the last batch was executed more than 1 hour ago will be killed.

you can also use use case/esac

case "$string" in
 "$pattern" ) echo "found";;
esac

Try this:

select * from your_table
where date >= '2020-10-01'  

You can also try

System.Environment.GetEnvironmentVariable("UserName");

This is what worked for me:

• Close all Sql Server referencing apps.
• Open Services in Control Panel.
• Find the "SQL Server (SQLEXPRESS)" entry and select properties.
• Stop the service (all Sql Server services).
• Enter "-m" at the Start parameters" fields.
• Start the service (click on Start button on General Tab).
• Open a Command Prompt (right click, Run as administrator if needed).

• Enter the command:

  osql -S localhost\SQLEXPRESS -E

  (or change localhost to whatever your PC is called).

• At the prompt type the following commands:

  CREATE LOGIN my_Login_here WITH PASSWORD = 'my_Password_here'

  go

  sp_addsrvrolemember 'my_Login_here', 'sysadmin'

  go

  quit

• Stop the "SQL Server (SQLEXPRESS)" service.

• Remove the "-m" from the Start parameters field (if still there).

• Start the service.

• In Management Studio, use the login and password you just created. This should give it admin permission.

pygame is not distributed via pip. See this link which provides windows binaries ready for installation.

1. Install python
2. Make sure you have python on your PATH
3. Download the appropriate wheel from this link
4. Install pip using this tutorial

5. Finally, use these commands to install pygame wheel with pip

   • Python 2 (usually called pip)

     • pip install file.whl

   • Python 3 (usually called pip3)

     • pip3 install file.whl

Another tutorial for installing pygame for windows can be found here. Although the instructions are for 64bit windows, it can still be applied to 32bit

CSS:

.imgMaxWidth {
    max-width:100px;
    height:auto;
}
.imgMaxHeight {
    max-height:100px;
    width:auto;
}

HTML:

<img src="image.jpg" class="imageToResize imgMaxHeight" />

jQuery:

<script type="text/javascript">
function onLoadF() {
    $('.imageToResize').each(function() {
        var imgWidth = $(this).width();
        if (imgWidth>100) {
            $(this).removeClass("imgMaxHeight").addClass("imgMaxWidth");
        }
    });
}
window.onload = onLoadF;
</script>

Simple solution for this common annoying issue:

Just go to your ".context.cs" file (located under ".context.tt" which located under your "*.edmx" file).

Then, add this line to your constructor:

public DBEntities() 
        : base("name=DBEntities") 
    { 
        this.Configuration.ProxyCreationEnabled = false; // ADD THIS LINE !
    }

hope this is helpful.

Java 8 solution

If you would like a solution which:

• Utilizes Java 8 lambdas
• Does not depend on any JUnit magic
• Allows you to check for multiple exceptions within a single test method
• Checks for an exception being thrown by a specific set of lines within your test method instead of any unknown line in the entire test method
• Yields the actual exception object that was thrown so that you can further examine it

Here is a utility function that I wrote:

public final <T extends Throwable> T expectException( Class<T> exceptionClass, Runnable runnable )
{
    try
    {
        runnable.run();
    }
    catch( Throwable throwable )
    {
        if( throwable instanceof AssertionError && throwable.getCause() != null )
            throwable = throwable.getCause(); //allows "assert x != null : new IllegalArgumentException();"
        assert exceptionClass.isInstance( throwable ) : throwable; //exception of the wrong kind was thrown.
        assert throwable.getClass() == exceptionClass : throwable; //exception thrown was a subclass, but not the exact class, expected.
        @SuppressWarnings( "unchecked" )
        T result = (T)throwable;
        return result;
    }
    assert false; //expected exception was not thrown.
    return null; //to keep the compiler happy.
}

(taken from my blog)

Use it as follows:

@Test
public void testThrows()
{
    RuntimeException e = expectException( RuntimeException.class, () -> 
        {
            throw new RuntimeException( "fail!" );
        } );
    assert e.getMessage().equals( "fail!" );
}

The statement about CMake being a "build generator" is a common misconception.

It's not technically wrong; it just describes HOW it works, but not WHAT it does.

In the context of the question, they do the same thing: take a bunch of C/C++ files and turn them into a binary.

So, what is the real difference?

• CMake is much more high-level. It's tailored to compile C++, for which you write much less build code, but can be also used for general purpose build. make has some built-in C/C++ rules as well, but they are useless at best.

• CMake does a two-step build: it generates a low-level build script in ninja or make or many other generators, and then you run it. All the shell script pieces that are normally piled into Makefile are only executed at the generation stage. Thus, CMake build can be orders of magnitude faster.

• The grammar of CMake is much easier to support for external tools than make's.

• Once make builds an artifact, it forgets how it was built. What sources it was built from, what compiler flags? CMake tracks it, make leaves it up to you. If one of library sources was removed since the previous version of Makefile, make won't rebuild it.

• Modern CMake (starting with version 3.something) works in terms of dependencies between "targets". A target is still a single output file, but it can have transitive ("public"/"interface" in CMake terms) dependencies. These transitive dependencies can be exposed to or hidden from the dependent packages. CMake will manage directories for you. With make, you're stuck on a file-by-file and manage-directories-by-hand level.

You could code up something in make using intermediate files to cover the last two gaps, but you're on your own. make does contain a Turing complete language (even two, sometimes three counting Guile); the first two are horrible and the Guile is practically never used.

To be honest, this is what CMake and make have in common -- their languages are pretty horrible. Here's what comes to mind:

• They have no user-defined types;
• CMake has three data types: string, list, and a target with properties. make has one: string;
• you normally pass arguments to functions by setting global variables.
  • This is partially dealt with in modern CMake - you can set a target's properties: set_property(TARGET helloworld APPEND PROPERTY INCLUDE_DIRECTORIES "${CMAKE_CURRENT_SOURCE_DIR}");
• referring to an undefined variable is silently ignored by default;

I think this is worth its own answer - if you're using Spring, you already have this with

Resource firstResource =
    context.getResource("http://www.google.fi/");
Resource anotherResource =
    context.getResource("classpath:some/resource/path/myTemplate.txt");

Like explained in the spring documentation and pointed out in the comments by skaffman.
