try this in windows:

pip install -U <Package_Name>

I tried all of above solution but didn't work for me.

Try this:-

Install required version of PHP(in my case 7.0) and then in terminal, type

sudo update-alternatives --config php

Output will be like this :-

Then you can switch to any version of PHP by simply entering the selection number(in my case 1).

Hope this may help other -:)

Just add the .vs folder to the .gitignore file.

Here is the template for Visual Studio from GitHub's collection of .gitignore templates, as an example:
https://github.com/github/gitignore/blob/master/VisualStudio.gitignore

If you have any trouble adding the .gitignore file, just follow these steps:

1. On the Team Explorer's window, go to Settings.

2. Then access Repository Settings.

3. Finally, click Add in the Ignore File section.

Done. ;)
This default file already includes the .vs folder.

Hi I have same issue tried almost everything. So, finally i resolved after 6 hour long struggle by debugging everything line by line.

classpath 'com.google.gms:google-services:3.0.0'

Google-services 3.0 Doesn't support firebase with Studio 3.0 with playServiceVersion: 11.6.0 or less.

implementation "com.google.firebase:firebase-messaging:$rootProject.ext.playServiceVersion"
implementation "com.google.firebase:firebase-core:$rootProject.ext.playServiceVersion"
implementation "com.firebase:firebase-jobdispatcher-with-gcm-dep:$rootProject.ext.jobdispatcherVersion"

Solution :

I have change google services to

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

And it support firebase services.

Hopefully somebody save his/her time.

Replace a hard coded version to + example:

implementation 'com.google.android.gms:play-services-base:+'
implementation 'com.google.android.gms:play-services-maps:+'

it is too late I know, howewer there is no succesfully answer. I found the answer from another website. I fixed the issue when I delete the System.Runtime assemblydependency. I deleted this.

<dependentAssembly> <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-4.1.2.0" newVersion="4.1.2.0"/> </dependentAssembly>

If all else fails, and if you are seeing this error while trying to import in a PyCharm "Python console" (or "Django console"):

Try restarting the console.

This is pretty embarassing, but it took me a while before I realized I had forgotten to do that.

Here's what happened:

Added a fresh app, then added a minimal model, then tried to import the model in the Python/Django console (PyCharm pro 2019.2). This raised the doesn't declare an explicit app_label error, because I had not added the new app to INSTALLED_APPS. So, I added the app to INSTALLED_APPS, tried the import again, but still got the same error.

Came here, read all the other answers, but nothing seemed to fit.

Finally it hit me that I had not yet restarted the Python console after adding the new app to INSTALLED_APPS.

Note: failing to restart the PyCharm Python console, after adding a new object to a module, is also a great way to get a very confusing ImportError: Cannot import name ...

It's simple

pd.factorize(df.purchase)[0]

Example:

labels, uniques = pd.factorize(['b', 'b', 'a', 'c', 'b'])`

labels
# array([0, 0, 1, 2, 0])

uniques
# array(['b', 'a', 'c'], dtype=object)

I know this is an old question, but I spent a couple of days looking through solutions which didn't work for me so maybe this helps someone else.

My project had a plugin which was throwing an error. I had to remove the plugin and add it again, and suddenly I could make it through the build process.

$ cordova add phonegap-plugin-push
$ cordova plugin add phonegap-plugin-push

I just ran the above and it was solved.

did you try this

{% load games_tags %} 

at the top instead of pygmentize?

Based on https://developer.android.com/studio/releases/gradle-plugin.html ...

The following table lists which version of Gradle is required for each version of the Android plugin for Gradle. For the best performance, you should use the latest possible version of both Gradle and the Android plugin.

So, the Plugin version with Required Gradle version should be match.

Another option is to use showtext package which supports more types of fonts (TrueType, OpenType, Type 1, web fonts, etc.) and more graphics devices, and avoids using external software such as Ghostscript.

# install.packages('showtext', dependencies = TRUE)
library(showtext)

Import some Google Fonts

# https://fonts.google.com/featured/Superfamilies
font_add_google("Montserrat", "Montserrat")
font_add_google("Roboto", "Roboto")

Load font from the current search path into showtext

# Check the current search path for fonts
font_paths()    
#> [1] "C:\\Windows\\Fonts"

# List available font files in the search path
font_files()    
#>   [1] "AcadEref.ttf"                                
#>   [2] "AGENCYB.TTF"                           
#> [428] "pala.ttf"

#> [430] "palabi.ttf"                                  
#> [431] "palai.ttf"

# syntax: font_add(family = "<family_name>", regular = "/path/to/font/file")
font_add("Palatino", "pala.ttf")

font_families()
#> [1] "sans"         "serif"        "mono"         "wqy-microhei"

myFont1 <- "Montserrat"
myFont2 <- "Roboto"
myFont3 <- "Palatino"

library(ggplot2)

a <- ggplot(mtcars, aes(x = wt, y = mpg)) +

  annotate("text", 1, 11, label = 'Roboto', hjust = 0,
           family = myFont2, size = 10) 

## On-screen device
print(a) 

## Save to PNG 
ggsave("plot_showtext.png", plot = a, 
       type = 'cairo',
       width = 6, height = 6, dpi = 150)  

## Save to PDF
ggsave("plot_showtext.pdf", plot = a, 
       device = cairo_pdf,
       width = 6, height = 6, dpi = 150)  

## turn showtext off if no longer needed
showtext_auto(FALSE) 

Edit: another workaround to use showtext in RStudio. Run the following code at the beginning of the R session (source)

trace(grDevices::png, exit = quote({
    showtext::showtext_begin()
}), print = FALSE)

Edit 2: Starting from version 0.9, showtext can work well with the RStudio graphics device (RStudioGD). Simply call showtext_auto() in the RStudio session and then the plots will be displayed correctly.

Here's my 2 cents:

import sys

map the path where the module file is located. In my case it was the desktop

sys.path.append('/Users/John/Desktop')

Either import the whole mapping module BUT then you have to use the .notation to map the classes like mapping.Shipping()

import mapping #mapping.py is the name of my module file

shipit = mapping.Shipment() #Shipment is the name of the class I need to use in the mapping module

Or import the specific class from the mapping module

from mapping import Mapping

shipit = Shipment() #Now you don't have to use the .notation

Make sure you aren't using two versions of google service.

For example having:

compile 'com.google.firebase:firebase-messaging:9.8.0'

and

compile 'com.google.firebase:firebase-ads:10.0.0'

If it is a windows system, then it may be because you are using 32 bit winpcap library in a 64 bit pc or vie versa. If it is a 64 bit pc then copy the winpcap library and header packet.lib and wpcap.lib from winpcap/lib/x64 to the winpcap/lib directory and overwrite the existing

I tried all the listed solutions above but nothing worked. This is what worked for me.

1. Look at the complete error message which you get when you use library(ggplot2).
2. It lists a couple of packages which are missing or have errors.
3. Uninstall and reinstall them.
4. ggplot should work now with a warning for version.

I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.

In case this helps someone, this is the easiest way I found, without requiring admin rights:

• make sure the directory you want to install your packages into exists. If you want to respect the convention, use: C:\Users\username\R\win-library\rversion (for example, something like: C:\Users\janebloggs\R\win-library\3.6)
• create a .Renviron file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER variable to be your custom path:

R_LIBS_USER=C:\Users\janebloggs\R\win-library\3.6

(feel free to add comments too, with lines starting with #)

If a .Renviron file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile. You can read about it in help(Startup).

Now it should be persistent between sessions!

As answered above, the right answer is to compile everything with VS2015, but for interest the following is my analysis of the problem.

This symbol does not appear to be defined in any static library provided by Microsoft as part of VS2015, which is rather peculiar since all others are. To discover why, we need to look at the declaration of that function and, more importantly, how it's used.

Here's a snippet from the Visual Studio 2008 headers:

_CRTIMP FILE * __cdecl __iob_func(void);
#define stdin (&__iob_func()[0])
#define stdout (&__iob_func()[1])
#define stderr (&__iob_func()[2])

So we can see that the job of the function is to return the start of an array of FILE objects (not handles, the "FILE *" is the handle, FILE is the underlying opaque data structure storing the important state goodies). The users of this function are the three macros stdin, stdout and stderr which are used for various fscanf, fprintf style calls.

Now let's take a look at how Visual Studio 2015 defines the same things:

_ACRTIMP_ALT FILE* __cdecl __acrt_iob_func(unsigned);
#define stdin (__acrt_iob_func(0))
#define stdout (__acrt_iob_func(1))
#define stderr (__acrt_iob_func(2))

So the approach has changed for the replacement function to now return the file handle rather than the address of the array of file objects, and the macros have changed to simply call the function passing in an identifying number.

So why can't they/we provide a compatible API? There are two key rules which Microsoft can't contravene in terms of their original implementation via __iob_func:

1. There must be an array of three FILE structures which can be indexed in the same manner as before.
2. The structural layout of FILE cannot change.

Any change in either of the above would mean existing compiled code linked against that would go badly wrong if that API is called.

Let's take a look at how FILE was/is defined.

First the VS2008 FILE definition:

struct _iobuf {
        char *_ptr;
        int   _cnt;
        char *_base;
        int   _flag;
        int   _file;
        int   _charbuf;
        int   _bufsiz;
        char *_tmpfname;
        };
typedef struct _iobuf FILE;

And now the VS2015 FILE definition:

typedef struct _iobuf
{
    void* _Placeholder;
} FILE;

So there is the crux of it: the structure has changed shape. Existing compiled code referring to __iob_func relies upon the fact that the data returned is both an array that can be indexed and that in that array the elements are the same distance apart.

The possible solutions mentioned in the answers above along these lines would not work (if called) for a few reasons:

FILE _iob[] = {*stdin, *stdout, *stderr};

extern "C" FILE * __cdecl __iob_func(void)
{
    return _iob;
}

The FILE array _iob would be compiled with VS2015 and so it would be laid out as a block of structures containing a void*. Assuming 32-bit alignment, these elements would be 4 bytes apart. So _iob[0] is at offset 0, _iob[1] is at offset 4 and _iob[2] is at offset 8. The calling code will instead expect FILE to be much longer, aligned at 32 bytes on my system, and so it will take the address of the returned array and add 0 bytes to get to element zero (that one is okay), but for _iob[1] it will deduce that it needs to add 32 bytes and for _iob[2] it will deduce that it needs to add 64-bytes (because that's how it looked in the VS2008 headers). And indeed the disassembled code for VS2008 demonstrates this.

A secondary issue with the above solution is that it copies the content of the FILE structure (*stdin), not the FILE * handle. So any VS2008 code would be looking at a different underlying structure to VS2015. This might work if the structure only contained pointers, but that's a big risk. In any case the first issue renders this irrelevant.

The only hack I've been able to dream up is one in which __iob_func walks the call stack to work out which actual file handle they are looking for (based on the offset added to the returned address) and returns a computed value such that it gives the right answer. This is every bit as insane as it sounds, but the prototype for x86 only (not x64) is listed below for your amusement. It worked okay in my experiments, but your mileage may vary - not recommended for production use!

I found that setting mRecycler.setLayoutFrozen(true); in the onRefresh method of the swipeContainer.

solved the problem for me.

swipeContainer.setOnRefreshListener(new   SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            orderlistRecycler.setLayoutFrozen(true);
            loadData(false);

        }
    });

It may happens because fake png files. You can use this command to check out fake pngs.

cd <YOUR_PROJECT/res/> && find . -name *.png | xargs pngcheck

And then,use ImageEditor(Ex, Pinta) to open fake pngs and re-save them to png.

Good luck.

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

Your issue is a very interesting one. Hadoop setup could be frustrating some time due to the complexity of the system and many moving parts involved. I think the issue you faced is definitely a firewall one. My hadoop cluster has similar setup. With a firewall rule added with command:

 sudo iptables -A INPUT -p tcp --dport 9000 -j REJECT

I'm able to see the exact issue:

15/03/02 23:46:10 INFO client.RMProxy: Connecting to ResourceManager at  /0.0.0.0:8032
java.net.ConnectException: Call From mybox/127.0.1.1 to localhost:9000 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused
     at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

You can verify your firewall settings with command:

/usr/local/hadoop/etc$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
REJECT     tcp  --  anywhere             anywhere             tcp dpt:9000 reject-with icmp-port-unreachable

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination   

Once the suspicious rule is identified, it could be deleted with a command like:

 sudo iptables -D INPUT -p tcp --dport 9000 -j REJECT 

Now, the connection should go through.

My solution was to add a space between the $ and the {.

For example:

@Value("${appclient.port:}")

becomes

@Value("$ {appclient.port:}")

Goto

1. File (Top Left Corner)
2. Project Structure
3. Under Module. Find the Dependence tab
4. press plus button (+) at top right.
5. You will find all the dependencies

Downloading the binaries for 64-bit from http://www.lfd.uci.edu/~gohlke/pythonlibs/, and installing it directly with pip in this order:

pip install numpy-1.12.0+mkl-cp36-cp36m-win64.whl
pip install scipy-0.18.1-cp36-cp36m-win64.whl
pip install matplotlib-2.0.0-cp36-cp36m-win64.whl

Note that you must place command prompt in the folder where you put the .whl files after downloading them, and you must run it as administrator, worked for me on Windows 10 64-bit now python is up and running.

Just execute this command in the spark directory:

Save and restart your shell. It works for me for Spark 1.1.0 and Spark 1.5.1 on OS X.

Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.

In my case the none of the answers above worked! since I had different productFlavors just adding repositories{ flatDir{ dirs 'libs' } }

did not work! I ended up with specifying exact location of libs directory:

repositories{
flatDir{
    dirs 'src/main/libs'
}

}

Guess one should introduce flatDirs like this when there's different productFlavors in build.gradle

If you are on ec2 and wanted to do mvn build then use -T option which tells maven to use number of threads while doing build

I know this question has already an answer that gives a solution. But I want to give you my two cents to help people to understand the problem. Getting same issue I've created a specific question. I got same problem, but only with PHPStorm. And exactly when I try to run test from the editor.

dyld is the dynamic linker

I sow that dyld was looking for /usr/local/lib/libpng15.15.dylib but inside my /usr/local/lib/ there was not. In that folder, I got libpng16.16.dylib.

Thanks to a comment, I undestand that my /usr/bin/php was a pointer to php 5.5.8. Instead, ... /usr/local/bin/php was 5.5.14. PHPStorm worked with /usr/bin/php that is default configuration. When I run php via console, I run /urs/local/bin/php.

So, ... If you get some dyld error, maybe you have some wrong php configuration. That's the reason because

$ brew update && brew upgrade
$ brew reinstall php55

But I dont know why this do not solve the problem to me. Maybe because I have

You need a ResourceLink in your META-INF/context.xml file to make the global resource available to the web application.

 <ResourceLink name="jdbc/mydb"
             global="jdbc/mydb"
              type="javax.sql.DataSource" />

in my case, I define the Activity in Manifest.xml and forgot to create any activity. So I created Activity and define it in manifest and my error solved!

You can define a Multi-module project structure, then you can set the configuration for sonar in one properties file in the root folder of your project, (Way #1)

I upgraded from 2010 to 2013 and after changing all the projects' Platform Toolset, I need to right-click on the Solution and choose Retarget... to make it work.

is it still actual?

As I can see you wrote <target depends="build-subprojects,build-project" name="build"/>, then you wrote <target name="build-subprojects"/> (it does nothing). Could it be a reason? Does this <echo message="${ant.project.name}: ${ant.file}"/> print appropriate message? If no then target is not running. Take a look at the next link http://www.sqaforums.com/showflat.php?Number=623277

I faced the same issue in below scenario yesterday. However I fixed it as shown below. But it would be great if someone can explain me as to why this error was coming specifically in my case.

pasted content of index.ejs file that gave the error in the browser when I run my node file "app.js". It has a route "/blogs" that redirects to "index.ejs" file.

<%= include partials/header %>
<h1>Index Page</h1>
<% blogs.forEach(function(blog){ %>
    <div>
        <h2><%= blog.title %></h2>
        <image src="<%= blog.image %>">
        <span><%= blog.created %></span>
        <p><%= blog.body %></p>
    </div>
<% }) %>
<%= include partials/footer %>

The error that came on the browser :

SyntaxError: missing ) after argument list in /home/ubuntu/workspace/RESTful/RESTfulBlogApp/views/index.ejs while compiling ejs

How I fixed it : I removed "=" in the include statements at the top and the bottom and it worked fine.

Regarding the original question asked in the title ...

• sudo apt-get install libtcnative-1

• or if you are on RHEL Linux yum install tomcat-native

The documentation states you need http://tomcat.apache.org/native-doc/

• sudo apt-get install libapr1.0-dev libssl-dev
• or RHEL yum install apr-devel openssl-devel

In my case I have moved plugins folder mistakenly to another folder while taking backup of my unnecessary projects. Then while I was trying to run the eclipse.exe I was getting the error-

The Eclipse executable launcher was unable to locate its companion shared library.

I have simply copied the plugins folder to eclipse root directory, and it was working fine for me.

If you have the folders backup in your computer then just copy and paste the folders on eclipse directory, you don't need to reinstall or change the ini file so far I realized.

in android 3.1.0 Above use below path to find signed version of APK

home/AndroidStudioProjects/<projedct name>/app/app-release.apk

and in windows

AndroidStudioProjects\{project name}\app\release\app-release.apk

In my case after spending many days on this issues a gentleman help on this issue below is the solution and it worked for me. Issue: While trying to connect SqlServer DB with Service account authentication using spring boot it throws below exception.

com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication. ClientConnectionId:ab942951-31f6-44bf-90aa-7ac4cec2e206 at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:2392) ~[mssql-jdbc-6.1.0.jre8.jar!/:na] Caused by: java.lang.UnsatisfiedLinkError: sqljdbc_auth (Not found in java.library.path) at java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:1462) ~[na:2.9 (04-02-2020)] Solution: Use JTDS driver with the following steps

1. Use JTDS driver insteadof sqlserver driver.

   ----------------- Dedicated Pick Update properties PROD using JTDS ----------------

   datasource.dedicatedpicup.url=jdbc:jtds:sqlserver://YourSqlServer:PortNo/DatabaseName;instance=InstanceName;domain=DomainName
   datasource.dedicatedpicup.jdbcUrl=${datasource.dedicatedpicup.url}
   datasource.dedicatedpicup.username=$da-XYZ
   datasource.dedicatedpicup.password=ENC(XYZ)
   datasource.dedicatedpicup.driver-class-name=net.sourceforge.jtds.jdbc.Driver
   

2. Remove Hikari in configuration properties.

   #datasource.dedicatedpicup.hikari.connection-timeout=60000 #datasource.dedicatedpicup.hikari.maximum-pool-size=5

3. Add sqljdbc4 dependency.

   com.microsoft.sqlserver sqljdbc4 4.0

4. Add Tomcatjdbc dependency.

   org.apache.tomcat tomcat-jdbc

5. Exclude HikariCP from spring-boot-starter-jdbc dependency.

   org.springframework.boot spring-boot-starter-jdbc com.zaxxer HikariCP

It worked for me after adding the following dependency in pom,

<dependency>
 <groupId>org.hibernate</groupId>
 <artifactId>hibernate-validator</artifactId>
 <version>4.3.0.Final</version>
</dependency>

To create a library:

File > New Module

select Android Library

To use the library add it as a dependancy:

File > Project Structure > Modules > Dependencies

Then add the module (android library) as a module dependency.

Run your project. It will work.

You don't have to use Tomcat installation as a server location. It is much easier just to copy the files in the ROOT folder.

Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.8\webapps, R-click on the ROOT folder and copy it. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or ../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder, R-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.

Source: HTTP Status 404 error in tomcat

This turned out to be a stupid error. My log4j wasn't configured to capture my error output. I was throwing configuration errors in the background and once I fixed those I was good to go and my request mappings worked fine.

just change the default folder for your R libraries in a directory with no Administrator rights, e.g.

.libPaths("C:/R/libs")

Check the VC++ directories, in VS 2010 these can be found in your project properties. Check whether $(WindowsSdkDir)\lib is included in the directories list, if not, manually add it. If you're building for X64 platform, you should select X64 from the “Platform” ComboBox, and make sure that $(WindowsSdkDir)\lib\x64 is included in the directories list.

Issue can be solved by adding CRT of msvcrtd.lib in the linker library. Because cryptlib.lib used CRT version of debug.

Just add your JDK path in windows environment variable. This solves in my case

--launcher.XXMaxPermSize

256m

Try to bump that value up!

You need to do two additional things after following the link that you have mentioned in your post:

One have to map the changed login cridentials in phpmyadmin's config.inc.php

and second, you need to restart your web and mysql servers..

php version is not the issue here..you need to go to phpmyadmin installation directory and find file config.inc.php and in that file put your current mysql password at line

$cfg['Servers'][$i]['user'] = 'root'; //mysql username here
$cfg['Servers'][$i]['password'] = 'password'; //mysql password here

2>LINK : fatal error LNK1104: cannot open file 'libboost_regex-vc120-mt-sgd-1_55.lib

In my case, bootstrap/bjam was not available (libraries were precompiled and committed to SCM) on old inherited project. Libraries did not have VC or BOOST versioning in their filenames eg: libboost_regex-mt-sgd.lib, however Processed /DEFAULTLIB:libboost_regex-vc120-mt-sgd-1_55.lib was somehow triggered automatically.

Fixed by manually adding the non-versioned filename to:

<AdditionalDependencies>$(DK_BOOST)\lib64\libboost_regex-mt-sgd.lib</AdditionalDependencies>

and blacklisting the ...vc120-mt-sgd-1_55.lib in

<IgnoreSpecificDefaultLibraries>libboost_regex-vc120-mt-sgd-1_55.lib</IgnoreSpecificDefaultLibraries>

You are missing commons-digester3-3.2.jar from Apache Commons Digester. If you are using Maven you can add:

<dependency>
    <groupId>commons-digester</groupId>
    <artifactId>commons-digester</artifactId>
    <version>2.1</version>
</dependency>

to your project dependencies.

Update: The jar from the latest download page has a slightly different package structure to what your application expects. You can use this older jar instead.

I had the same problem. I fixed it by makinbg the following entry in org.eclipse.wst.common.project.facet.core.xml

<runtime name="Apache Tomcat v7.0" />

Now this complete file looks like -

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
    <runtime name="Apache Tomcat v7.0" />
    <fixed facet="wst.jsdt.web" />
    <installed facet="java" version="1.5" />
    <installed facet="jst.web" version="2.3" />
    <installed facet="wst.jsdt.web" version="1.0" />
</faceted-project>

You mention Haxe/NME but you seem to instinctively dislike it. However, my experience with it has been very positive. Sure, the API is a reimplementation of the Flash API, but you're not limited to targeting Flash, you can also compile to HTML5 or native Windows, Mac, iOS and Android apps. Haxe is a pleasant, modern language similar to Java or C#.

If you're interested, I've written a bit about my experience using Haxe/NME: link

Check out this blog. It has a ton of information. Also if installing through brew don´t miss this note:

You may need to link the Java bindings into the Java Extensions folder:

 $ sudo mkdir -p /Library/Java/Extensions
 $ sudo ln -s /usr/local/lib/libsvnjavahl-1.dylib /Library/Java/Extensions/libsvnjavahl-1.dylib

1) Download the JDBC Driver here.

2) unzip the file and go to sqljdbc_version\fra\auth\x86 or \x64
3) copy the sqljdbc_auth.dll to C:\Program Files\Java\jre_Version\bin
4) Finally restart eclipse

The issue was fixed by doing the following steps.

1. Eclipse finds the JAVA executables from 'C:\ProgramData\Oracle\Java\javapath'

2. The folder structure will contain shortcuts to the below executables,
   i. java.exe
   ii. javaw.exe
   iii. javaws.exe

3. For me the executable paths were pointing to my Program Files(x86) (home for 32 bit applications) folder location

4. I corrected it to Program Files (which homes 64-bit applications) and the issue got resolved

Please find the screenshot for the same.

You can use packageVersion to see what version of a package is loaded

> packageVersion("snow")
[1] ‘0.3.9’

Although it sounds like you want to see what version of R you are running, in which case @Justin's sessionInfo suggestion is the way to go

Install a JDK.

It's possible to get Eclipse to run with a JRE, or at least it used to be, but why bother? Eclipse is much happier with a JDK.

Remember that the JRE that is used to run Eclipse does not have to be the JRE that Eclipse uses to run an application.

PS. I'm assuming here that the original poster's problem was getting Eclipse to start, and not (as some other Answers seem to address) getting Eclipse to start an application.

I had the same problem, and it turned out I hadn't installed the library.

this link was super usefull.

http://help.directadmin.com/item.php?id=368

This seems like that the servlet api version which you using is older than the xsd you are using in web.xml eg 3.0

use this one ****http://java.sun.com/xml/ns/javaee/" id="WebApp_ID" version="2.5"> ****

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." />

Replace it by:

<context:component-scan base-package="org.assessme.com." />

It is because your Autowired service is not scanned by Spring since it is not in the right package.

Gson is also good for it: http://code.google.com/p/google-gson/

" Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of. "

Check the API examples: https://sites.google.com/site/gson/gson-user-guide#TOC-Overview More examples: http://www.mkyong.com/java/how-do-convert-java-object-to-from-json-format-gson-api/

The full list is:

DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)

See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html

They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):

    db      0x55                ; just the byte 0x55
    db      0x55,0x56,0x57      ; three bytes in succession
    db      'a',0x55            ; character constants are OK
    db      'hello',13,10,'$'   ; so are string constants
    dw      0x1234              ; 0x34 0x12
    dw      'A'                 ; 0x41 0x00 (it's just a number)
    dw      'AB'                ; 0x41 0x42 (character constant)
    dw      'ABC'               ; 0x41 0x42 0x43 0x00 (string)
    dd      0x12345678          ; 0x78 0x56 0x34 0x12
    dq      0x1122334455667788  ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    ddq     0x112233445566778899aabbccddeeff00
    ; 0x00 0xff 0xee 0xdd 0xcc 0xbb 0xaa 0x99
    ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    do      0x112233445566778899aabbccddeeff00 ; same as previous
    dd      1.234567e20         ; floating-point constant
    dq      1.234567e20         ; double-precision float
    dt      1.234567e20         ; extended-precision float

DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.

A possibly more generic method is to:

• install non-headless version of the openjdk,
• install, run and close eclipse.
• uninstall the openjdk
• install oracle's JDK

I had the same problem when tom?at could not find the class. Try to view other log files. Sometimes No class def found error appears in different log files:

• tomcat8-stderr
• localhost

Just as an update to @Patricia's comment in the accepted answer and @Fraser's comment for the original question, if you have access to CMake 3.11+ you can make use of CMake's FetchContent function.

CMake's FetchContent page uses googletest as an example!

I've provided a small modification of the accepted answer:

cmake_minimum_required(VERSION 3.11)
project(basic_test)

set(GTEST_VERSION 1.6.0 CACHE STRING "Google test version")

If you start tomcat from startup.bat, you need to add a system variable :JAVA_OPTS as name and the parameters that you wants (in your case :

-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5

I resolved my trouble in correcting the "Additional Library Directory", this one was wrong in indicating "$(SolutionDir)\Release", I changed it in "$(SolutionDir)\$(IntDir)"

To correct it, open your project properties -> Configuration Properties -> Linker -> General -> Additional Library Directory

I hope this will help some poeples with the same trouble ;)

For the Python module import to work, you must have "src" in your path, not "gen_py/lib".

When processing an import like import gen_py.lib, it looks for a module gen_py, then looks for a submodule lib.

As the module gen_py won't be in "../gen_py/lib" (it'll be in ".."), the path you added will do nothing to help the import process.

Depending on where you're running it from, try adding the relative path to the "src" folder. Perhaps it's sys.path.append('..'). You might also have success running the script while inside the src folder directly, via relative paths like python main/MyServer.py

I have faced this particular error when I didn't defined the main() function. Check if the main() function exists or check the name of the function letter by letter as Timothy described above or check if the file where the main function is located is included to your project.

The problem appeared first right after patching DCEVM with version: DCEVM-8u181-installer.jar.

Then, temoving the flag -XX:+UseG1GC from eclipse.ini it fixed the issue.

Well, the error message tells you what to do: add the path where Jacob.dll resides to java.library.path. You can do that on the command line like this:

java -Djava.library.path="dlls" ...

(assuming Jacob.dll is in the "dlls" folder)

Also see java.lang.UnsatisfiedLinkError no *****.dll in java.library.path

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

Include <tchar.h> which has the line:

#define _tWinMain wWinMain

For me the problem was a wrong include directory. I have no idea why this caused the error with the seemingly missing lib as the include directory only contains the header files. And the library directory had the correct path set.

Add below code in your client code :

static {
    Security.insertProviderAt(new BouncyCastleProvider(),1);
 }

with this there is no need to add any entry in java.security file.

Using the:

standard.jar

Resolves the problem.

I had this issue also. I had an old JDK1.8.0_05. I installed the newest JDK1.8.0_111 and everything works great now. Just be sure to update your environment variable.

I am on Windows 7 64 bit. Using Eclipse Neon 1a.

Hope that helps someone.

Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll file.

I too got the warning while starting the server and you don't have to worry about this if you are testing or developing. This is meant to be on production purposes. After putting the tcnative-1.dll file inside the bin folder of Apache Tomcat 7 following are the output in the stderr file,

I encountered the same problem when I switched to AnnotationSessionFactoryBean. I was using entity.hbm.xml before.

I found that My class was missing following annotation which resolved the issue in my case:

@Entity
@Table(name = "MyTestEntity")
@XmlRootElement

You can use the * operator before an iterable to expand it within the function call. For example:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

From the python documentation:

If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the ** operator.

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

• To undo once: C-/
• To undo twice: C-/ C-/

• To redo once, immediately after undoing: C-g C-/
• To redo twice, immediately after undoing: C-g C-/ C-/. Note that C-g is not repeated.

• To undo immediately again, once: C-g C-/
• To undo immediately again, twice: C-g C-/ C-/

• To redo again, the same…

If you have pressed any keys (whether typing characters or just moving the cursor) since your last undo command, there is no need to type C-g before your next undo/redo. C-g is just a safe key to hit that does nothing on its own, but counts as a non-undo key to signal the end of your undo sequence. Pressing another command such as C-f would work too; it’s just that it would move the cursor from where you had it.

If you hit C-g or another command when you didn’t mean to, and you are now undoing in the wrong direction, simply hit C-g to reverse your direction again. You will have to undo all the way through your accidental redos and undos before you get to the undos you want, but if you just keep hitting C-/, you will eventually reach the state you want. In fact, every state the buffer has ever been in is reachable, if you hit C-g once and then press C-/ enough times.

Alternative shortcuts for undo, other than C-/, are C-_, C-x u, and M-x undo.

See Undo in the Emacs Manual for more details on Emacs’s undo system.

before going for the step "compile -DIPLIB=NONE filename.cxx" take the path of VIsual Studio installation upto the vcvarsall batch file and change the configuration as shown below.

*C:\apps\MVS9\VC\vcvarsall.bat x86_amd64*

now next step should be

compile -64bit -DIPLIB=none filename.cxx

this solved the problem for me

I would do it in the following way:

(If working with MSVC, ignore the GCC compilation commands)

Suppose that I have a C++ class named AAA, defined in files aaa.h, aaa.cpp, and that the class AAA has a method named sayHi(const char *name), that I want to enable for C code.

The C++ code of class AAA - Pure C++, I don't modify it:

aaa.h

#ifndef AAA_H
#define AAA_H

class AAA {
    public:
        AAA();
        void sayHi(const char *name);
};

#endif

aaa.cpp

#include <iostream>

#include "aaa.h"

AAA::AAA() {
}

void AAA::sayHi(const char *name) {
    std::cout << "Hi " << name << std::endl;
}

Compiling this class as regularly done for C++. This code "does not know" that it is going to be used by C code. Using the command:

g++ -fpic -shared aaa.cpp -o libaaa.so

Now, also in C++, creating a C connector. Defining it in files aaa_c_connector.h, aaa_c_connector.cpp. This connector is going to define a C function, named AAA_sayHi(cosnt char *name), that will use an instance of AAA and will call its method:

aaa_c_connector.h

#ifndef AAA_C_CONNECTOR_H 
#define AAA_C_CONNECTOR_H 

#ifdef __cplusplus
extern "C" {
#endif

void AAA_sayHi(const char *name);

#ifdef __cplusplus
}
#endif


#endif

aaa_c_connector.cpp

// Inside this "extern C" block, I can implement functions in C++, which will externally 
//   appear as C functions (which means that the function IDs will be their names, unlike
//   the regular C++ behavior, which allows defining multiple functions with the same name
//   (overloading) and hence uses function signature hashing to enforce unique IDs),


static AAA *AAA_instance = NULL;

void lazyAAA() {
    if (AAA_instance == NULL) {
        AAA_instance = new AAA();
    }
}

void AAA_sayHi(const char *name) {
    lazyAAA();
    AAA_instance->sayHi(name);
}

#ifdef __cplusplus
}
#endif

Compiling it, again, using a regular C++ compilation command:

g++ -fpic -shared aaa_c_connector.cpp -L. -laaa -o libaaa_c_connector.so

Now I have a shared library (libaaa_c_connector.so), that implements the C function AAA_sayHi(const char *name). I can now create a C main file and compile it all together:

main.c

#include "aaa_c_connector.h"

int main() {
    AAA_sayHi("David");
    AAA_sayHi("James");

    return 0;
}

Compiling it using a C compilation command:

gcc main.c -L. -laaa_c_connector -o c_aaa

I will need to set LD_LIBRARY_PATH to contain $PWD, and if I run the executable ./c_aaa, I will get the output I expect:

Hi David
Hi James

EDIT:

On some linux distributions, -laaa and -lstdc++ may also be required for the last compilation command. Thanks to @AlaaM. for the attention

Some readers will have another issue and need this fix. read the links below. the same problem occured with visual studio 2015 with the advent of windows sdk 10 which brings up libucrt. ucrt is the windows implementation of C Runtime (CRT) aka the posix runtime library. You most likely have code that was ported from unix... Welcome to the drawback

I've had a lot of problems trying to get Eclipse to accept as much memory as I'd like it to be able to use (between 2 and 4 gigs for example).

Open eclipse.ini in the Eclipse installation directory. You should be able to change the memory sizes after -vmargs up to 1024 without a problem up to some maximum value that's dependent on your system. Here's that section on my Linux box:

-vmargs
-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=512m
-Xms512m
-Xmx1024m

And here's that section on my Windows box:

-vmargs
-Xms256m
-Xmx1024m

But, I've failed at setting it higher than 1024 megs. If anybody knows how to make that work, I'd love to know.

EDIT: 32bit version of juno seems to not accept more than Xmx1024m where the 64 bit version accept 2048.

EDIT: Nick's post contains some great links that explain two different things:

• The problem is largely dependent on your system and the amount of contiguous free memory available, and
• By using javaw.exe (on Windows), you may be able to get a larger allocated block of memory.

I have 8 gigs of Ram and can't set -Xmx to more than 1024 megs of ram, even when a minimal amount of programs are loaded and both windows/linux report between 4 and 5 gigs of free ram.

You can change the port number:

Open the server tab in eclipse -> right click open click on open---->you can change the port number.

Run the application with http://localhost:8080/Applicationname it will give output and also check http://localhost:8080/Applicationname/index.jsp

In general I would consider setting up of an environment variable (like PYTHONPATH) to be a bad practice. While this might be fine for a one off debugging but using this as
a regular practice might not be a good idea.

Usage of environment variable leads to situations like "it works for me" when some one
else reports problems in the code base. Also one might carry the same practice with the test environment as well, leading to situations like the tests running fine for a particular developer but probably failing when some one launches the tests.

First, you'll want to ensure the directory to your native library is on the java.library.path. See how to do that here. Then, you can call System.loadLibrary(nativeLibraryNameWithoutExtension) - making sure to not include the file extension in the name of your library.

What worked for me on WAMP was modifying file: \Wamp64\alias\phpmyadmin.conf, lines:

 php_admin_value max_execution_time 600
 php_admin_value max_input_time 600

I did not have to change the library file.

Except the way described in the approved answer, there's another way if you have single native libs in your project.

• in Project properties->Java Build Path->Tab "Source" there's a list of your source-folders
• For each entry, there's "Native library locations", which also supports paths within the workspace.
• This will make Eclipse add it to your java.library.path.

You need to do a couple of things to use the library:

1. Make sure that you have both the *.lib and the *.dll from the library you want to use. If you don't have the *.lib, skip #2

2. Put a reference to the *.lib in the project. Right click the project name in the Solution Explorer and then select Configuration Properties->Linker->Input and put the name of the lib in the Additional Dependencies property.

3. You have to make sure that VS can find the lib you just added so you have to go to the Tools menu and select Options... Then under Projects and Solutions select VC++ Directories,edit Library Directory option. From within here you can set the directory that contains your new lib by selecting the 'Library Files' in the 'Show Directories For:' drop down box. Just add the path to your lib file in the list of directories. If you dont have a lib you can omit this, but while your here you will also need to set the directory which contains your header files as well under the 'Include Files'. Do it the same way you added the lib.

After doing this you should be good to go and can use your library. If you dont have a lib file you can still use the dll by importing it yourself. During your applications startup you can explicitly load the dll by calling LoadLibrary (see: http://msdn.microsoft.com/en-us/library/ms684175(VS.85).aspx for more info)

Cheers!

EDIT

Remember to use #include < Foo.h > as opposed to #include "foo.h". The former searches the include path. The latter uses the local project files.

The error you mean is due to missing additional include path. Try adding it with: INCLUDEPATH += C:\path\to\include\files\ Hope it works. Regards.

The PDB file is typically used to store debug information. This warning is caused probably because the file vc80.pdb is not found when linking the target object file. Read the MSDN entry on LNK4099 here.

Alternatively, you can turn off debug information generation from the Project Properties > Linker > Debugging > Generate Debug Info field.

The native library file name has to correspond to the Jar file name. This is very very important. Please make sure that jar name and dll name are same. Also,please see the post from Fabian Steeg My download for jawin was containing different names for dll and jar. It was jawin.jar and jawind.dll, note extra 'd' in dll file name. I simply renamed it to jawin.dll and set it as a native library in eclipse as mentioned in post "http://www.eclipsezone.com/eclipse/forums/t49342.html"

OK, so I found the answer from http://binglongx.wordpress.com/2009/01/26/visual-c-does-not-generate-lib-file-for-a-dll-project/ says that this problem was caused by not exporting any symbols and further instructs on how to export symbols to create the lib file. To do so, add the following code to your .h file for your DLL.

#ifdef BARNABY_EXPORTS
#define BARNABY_API __declspec(dllexport)
#else
#define BARNABY_API __declspec(dllimport)
#endif

Where BARNABY_EXPORTS and BARNABY_API are unique definitions for your project. Then, each function you export you simply precede by:

BARNABY_API int add(){
}

This problem could have been prevented either by clicking the Export Symbols box on the new project DLL Wizard or by voting yes for lobotomies for computer programmers.

Like it can be seen in other answers you'll have to open a Developer Command Prompt offered in your version of Visual Studio to have dumpbin.exe in your execution path. Otherwise, you can set the necessary environment variables by hand.

dumpbin /EXPORTS yourlibrary.lib will usually show just a tiny list of symbols. In many cases, it won't show the functions the library exports.

dumpbin /SYMBOLS /EXPORTS yourlibrary.lib will show that symbols, but also an incredibly huge amount of other symbos. So, you got to filter them, possibly with a pipe to findstr (if you want a MS-Windows tool), or grep.

Searching the Static keyword using one of these tools seems to be a good hint.

Others have adequately explained what a static library is, but I'd like to point out some of the caveats of using static libraries, at least on Windows:

• Singletons: If something needs to be global/static and unique, be very careful about putting it in a static library. If multiple DLLs are linked against that static library they will each get their own copy of the singleton. However, if your application is a single EXE with no custom DLLs, this may not be a problem.

• Unreferenced code removal: When you link against a static library, only the parts of the static library that are referenced by your DLL/EXE will get linked into your DLL/EXE.

  For example, if mylib.lib contains a.obj and b.obj and your DLL/EXE only references functions or variables from a.obj, the entirety of b.obj will get discarded by the linker. If b.obj contains global/static objects, their constructors and destructors will not get executed. If those constructors/destructors have side effects, you may be disappointed by their absence.

  Likewise, if the static library contains special entrypoints you may need to take care that they are actually included. An example of this in embedded programming (okay, not Windows) would be an interrupt handler that is marked as being at a specific address. You also need to mark the interrupt handler as an entrypoint to make sure it doesn't get discarded.

  Another consequence of this is that a static library may contain object files that are completely unusable due to unresolved references, but it won't cause a linker error until you reference a function or variable from those object files. This may happen long after the library is written.

• Debug symbols: You may want a separate PDB for each static library, or you may want the debug symbols to be placed in the object files so that they get rolled into the PDB for the DLL/EXE. The Visual C++ documentation explains the necessary options.

• RTTI: You may end up with multiple type_info objects for the same class if you link a single static library into multiple DLLs. If your program assumes that type_info is "singleton" data and uses &typeid() or type_info::before(), you may get undesirable and surprising results.

If you want to open inside the app itself instead of leaving the app you can import SafariServices and work it out.

present(vc, animated: true, completion: nil)

I searched for curl on the cygwin packages part of their home page.

I found this link http://cygwin.com/packages/curl/. But that wasn't helpful because I couldn't download anything

So I searched for the curl-7.20.1-1 cygwin on Google. I found this helpful site mirrors.xmission.com/cygwin/release/curl/

That site had a link to download curl-7.20.1-1.tar.bz2. I unzipped it using 7zip. It unzips it into ./user/bin/ or something so I had to find curl.exe in the local /usr/bin folder and put it into my /bin folder of c:\cygwin

Finally I could use cURL!

This drove me crazy. I hope it helps someone!

Building on the previous answer, this bash one-liner should give you what you're looking for. It displays the git blame history for a particular line of a particular file, through the last 5 revisions:

LINE=10 FILE=src/options.cpp REVS=5; for commit in $(git rev-list -n $REVS HEAD $FILE); do git blame -n -L$LINE,+1 $commit -- $FILE; done

In the output of this command, you might see the content of the line change, or the line number displayed might even change, for a particular commit.

This often indicates that the line was added for the first time, after that particular commit. It could also indicate the line was moved from another part of the file.

Java API specifies two methods you could use: indexOf(Object obj) and lastIndexOf(Object obj). The first one returns the index of the element if found, -1 otherwise. The second one returns the last index, that would be like searching the list backwards.

In order to get the refresh token you have to add both approval_prompt=force and access_type="offline" If you are using the java client provided by Google it will look like this:

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, getClientSecrets(), scopes)
            .build();

AuthorizationCodeRequestUrl authorizationUrl =
            flow.newAuthorizationUrl().setRedirectUri(callBackUrl)
                    .setApprovalPrompt("force")
                    .setAccessType("offline");

If you don't need it to be human-readable/editable, the easiest solution is to just use pickle.

To write:

with open(the_filename, 'wb') as f:
    pickle.dump(my_list, f)

To read:

with open(the_filename, 'rb') as f:
    my_list = pickle.load(f)

If you do need them to be human-readable, we need more information.

If my_list is guaranteed to be a list of strings with no embedded newlines, just write them one per line:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write(s + '\n')

with open(the_filename, 'r') as f:
    my_list = [line.rstrip('\n') for line in f]

If they're Unicode strings rather than byte strings, you'll want to encode them. (Or, worse, if they're byte strings, but not necessarily in the same encoding as your system default.)

If they might have newlines, or non-printable characters, etc., you can use escaping or quoting. Python has a variety of different kinds of escaping built into the stdlib.

Let's use unicode-escape here to solve both of the above problems at once:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write((s + u'\n').encode('unicode-escape'))

with open(the_filename, 'r') as f:
    my_list = [line.decode('unicode-escape').rstrip(u'\n') for line in f]

You can also use the 3.x-style solution in 2.x, with either the codecs module or the io module:*

import io

with io.open(the_filename, 'w', encoding='unicode-escape') as f:
    f.writelines(line + u'\n' for line in my_list)

with open(the_filename, 'r') as f:
    my_list = [line.rstrip(u'\n') for line in f]

_{* TOOWTDI, so which is the one obvious way? It depends… For the short version: if you need to work with Python versions before 2.6, use codecs; if not, use io.}

You open the variable "file" as a read only then attempt to write to it:

file = open('ValidEmails.txt','r')

Instead, use the 'w' flag.

file = open('ValidEmails.txt','w')
...
file.write(email)

This is the most coder-friendly version of specifying a unicode character:

degree_sign= u'\N{DEGREE SIGN}'

Note: must be a capital N in the \N construct to avoid confusion with the '\n' newline character. The character name inside the curly braces can be any case.

It's easier to remember the name of a character than its unicode index. It's also more readable, ergo debugging-friendly. The character substitution happens at compile time: the .py[co] file will contain a constant for u'°':

>>> import dis
>>> c= compile('u"\N{DEGREE SIGN}"', '', 'eval')
>>> dis.dis(c)
  1           0 LOAD_CONST               0 (u'\xb0')
              3 RETURN_VALUE
>>> c.co_consts
(u'\xb0',)
>>> c= compile('u"\N{DEGREE SIGN}-\N{EMPTY SET}"', '', 'eval')
>>> c.co_consts
(u'\xb0-\u2205',)
>>> print c.co_consts[0]

Use setItem and getItem if you want to write simple strings to localStorage. Also you should be using text() if it's the text you're after as you say, else you will get the full HTML as a string.

Sample using .text()

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// alert the value to check if we got it
alert(localStorage.getItem('test'));

JSFiddle: https://jsfiddle.net/f3zLa3zc/

Storing the HTML itself

// get html
var html = $('#test')[0].outerHTML;

// set localstorage
localStorage.setItem('htmltest', html);

// test if it works
alert(localStorage.getItem('htmltest'));

JSFiddle:
https://jsfiddle.net/psfL82q3/1/

Update on user comment

A user want to update the localStorage when the div's content changes. Since it's unclear how the div contents changes (ajax, other method?) contenteditable and blur() is used to change the contents of the div and overwrite the old localStorage entry.

// get the text
var text = $('#test').text();

// set the item in localStorage
localStorage.setItem('test', text);

// bind text to 'blur' event for div
$('#test').on('blur', function() {

    // check the new text
    var newText = $(this).text();

    // overwrite the old text
    localStorage.setItem('test', newText);

    // test if it works
    alert(localStorage.getItem('test'));

});

If we were using ajax we would instead trigger the function it via the function responsible for updating the contents.

You can use the window object to get at it .

window['myVar']

window has a reference to all global variables and global functions you are using.

You enter the

if (!(cin >> input_var))

statement if an error occurs when taking the input from cin. If an error occurs then an error flag is set and future attempts to get input will fail. That's why you need

cin.clear();

to get rid of the error flag. Also, the input which failed will be sitting in what I assume is some sort of buffer. When you try to get input again, it will read the same input in the buffer and it will fail again. That's why you need

cin.ignore(10000,'\n');

It takes out 10000 characters from the buffer but stops if it encounters a newline (\n). The 10000 is just a generic large value.

I got this error generating a data frame consisting of timestamps and data:

df = pd.DataFrame({'data':value}, index=pd.DatetimeIndex(timestamp))

Adding the suggested solution works for me:

df = pd.DataFrame({'data':value}, index=pd.DatetimeIndex(timestamp), dtype=float))

Thanks to a related question, I found out that I need to "checkout" the remote branch as a new local branch, and specify a new local branch name.

git checkout -b newlocalbranchname origin/branch-name

Or you can do:

git checkout -t origin/branch-name

The latter will create a branch that is also set to track the remote branch.

Update: It's been 5 years since I originally posted this question. I've learned a lot and git has improved since then. My usual workflow is a little different now.

If I want to fetch the remote branches, I simply run:

git pull

This will fetch all of the remote branches and merge the current branch. It will display an output that looks something like this:

From github.com:andrewhavens/example-project
   dbd07ad..4316d29  master     -> origin/master
 * [new branch]      production -> origin/production
 * [new branch]      my-bugfix-branch -> origin/my-bugfix-branch
First, rewinding head to replay your work on top of it...
Fast-forwarded master to 4316d296c55ac2e13992a22161fc327944bcf5b8.

Now git knows about my new my-bugfix-branch. To switch to this branch, I can simply run:

git checkout my-bugfix-branch

Normally, I would need to create the branch before I could check it out, but in newer versions of git, it's smart enough to know that you want to checkout a local copy of this remote branch.

Isn't this maybe the most elegant?

REPLACE 
INTO component_psar (tbl_id, row_nr, col_1, col_2, col_3, col_4, col_5, col_6, unit, add_info, fsar_lock) 
VALUES('2', '1', '1', '1', '1', '1', '1', '1', '1', '1', 'N')

see: http://dev.mysql.com/doc/refman/5.7/en/replace.html

This also works:

    ...
    WHERE
        (FirstName IS NULL OR FirstName = ISNULL(@FirstName, FirstName)) AND
        (LastName IS NULL OR LastName = ISNULL(@LastName, LastName)) AND
        (Title IS NULL OR Title = ISNULL(@Title, Title))

You mean a DOS command such as below will do the job displaying installed .NET frameworks:

wmic /namespace:\\root\cimv2 path win32_product where "name like '%%.NET%%'" get version

The following may then be displayed:

Version
4.0.30319

WMIC is quite useful once you master using it, much easier than coding WMI in scripts depending on what you want to achieve.

This SO thread will solve your problem. Solution in short:

$url = 'http://www.google.co.in/intl/en_com/images/srpr/logo1w.png';
$img = '/my/folder/my_image.gif';
file_put_contents($img, file_get_contents($url));

Old tread...? Well, someone may bump into this...

Please check out http://telamenta.com/techarticle/php-explode-newlines-and-you

Rather than using:

$values = explode("\n", $value_string);

Use a safer method like:

$values = preg_split('/[\n\r]+/', $value_string);

Unfortunately the performance of getScaledInstance() is very poor if not problematic.

The alternative approach is to create a new BufferedImage and and draw a scaled version of the original on the new one.

BufferedImage resized = new BufferedImage(newWidth, newHeight, original.getType());
Graphics2D g = resized.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
    RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(original, 0, 0, newWidth, newHeight, 0, 0, original.getWidth(),
    original.getHeight(), null);
g.dispose();

newWidth,newHeight indicate the new BufferedImage size and have to be properly calculated. In case of factor scaling:

int newWidth = new Double(original.getWidth() * widthFactor).intValue();

PHP 7.0 $_SERVER varibales have changed. var_dump it and see how it fits your reqs.

some of them giving remote details are, REMOTE_ADDR HTTP_X_FORWARDED_FOR HTTP_CF_CONNECTING_IP HTTP_CF_IPCOUNTRY

From your comment:

this line DateTime Date = reader.GetDateTime(0); was throwing the exception

The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:

SELECT * from INFO

Replace it with a query that retrieves only the two columns you're interested in:

SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO

Then try reading the values again:

var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1);  // equivalent to time(7) from your database

Or:

var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];

This was pretty well answered over here: How to make a YouTube embedded video a full page width one?

If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)

<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

of the video it should play on load. Here's a demo over at jsfiddle.

I fixed this (for development) with a simple nginx proxy...

Here is the really simple and short solution with SimpleEntry:

AbstractMap.Entry<String, Float> myTwoCents=new AbstractMap.SimpleEntry<>("maximum possible performance reached" , 99.9f);

String question=myTwoCents.getKey();
Float answer=myTwoCents.getValue();

Only uses Java built in functions and it comes with the type safty benefit.

you can show one line output then set property Line=0 and show multiple line output then set property Line=1 and more

[self.yourLableName sizeToFit];

There is one thing that may be optimized in the suggested solutions. Having many calls to Replace() makes the code to do multiple passes over the same string. With very long strings the solutions may be slow because of CPU cache capacity misses. May be one should consider replacing multiple strings in a single pass.

In addition to K.S's response of creating a StringBuilderPlus class and utilising ther adapter pattern to extend a final class, if you make use of generics and return the StringBuilderPlus object in the new append and appendLine methods, you can make use of the StringBuilders many append methods for all different types, while regaining the ability to string string multiple append commands together, as shown below

public class StringBuilderPlus {

    private final StringBuilder stringBuilder;

    public StringBuilderPlus() {
        this.stringBuilder = new StringBuilder();
    }

    public <T> StringBuilderPlus append(T t) {
        stringBuilder.append(t);
        return this;
    }

    public <T> StringBuilderPlus appendLine(T t) {
        stringBuilder.append(t).append(System.lineSeparator());
        return this;
    }

    @Override
    public String toString() {
        return stringBuilder.toString();
    }

    public StringBuilder getStringBuilder() {
        return stringBuilder;
    }
}

you can then use this exactly like the original StringBuilder class:

StringBuilderPlus stringBuilder = new StringBuilderPlus();
stringBuilder.appendLine("test")
    .appendLine('c')
    .appendLine(1)
    .appendLine(1.2)
    .appendLine(1L);

stringBuilder.toString();

You could also create a custom model field type - see http://docs.djangoproject.com/en/dev/howto/custom-model-fields/#howto-custom-model-fields

In this case, you could 'inherit' from the built-in IntegerField and override its validation logic.

The more I think about this, I realize how useful this would be for many Django apps. Perhaps a IntegerRangeField type could be submitted as a patch for the Django devs to consider adding to trunk.

This is working for me:

from django.db import models

class IntegerRangeField(models.IntegerField):
    def __init__(self, verbose_name=None, name=None, min_value=None, max_value=None, **kwargs):
        self.min_value, self.max_value = min_value, max_value
        models.IntegerField.__init__(self, verbose_name, name, **kwargs)
    def formfield(self, **kwargs):
        defaults = {'min_value': self.min_value, 'max_value':self.max_value}
        defaults.update(kwargs)
        return super(IntegerRangeField, self).formfield(**defaults)

Then in your model class, you would use it like this (field being the module where you put the above code):

size = fields.IntegerRangeField(min_value=1, max_value=50)

OR for a range of negative and positive (like an oscillator range):

size = fields.IntegerRangeField(min_value=-100, max_value=100)

What would be really cool is if it could be called with the range operator like this:

size = fields.IntegerRangeField(range(1, 50))

But, that would require a lot more code since since you can specify a 'skip' parameter - range(1, 50, 2) - Interesting idea though...

That may help those who works on Kotlin you can use extension function so create a kotlin file let's say "util.kt" and add this piece of code

fun Fragment.addChildFragment(fragment: Fragment, frameId: Int) {

    val transaction = childFragmentManager.beginTransaction()
    transaction.replace(frameId, fragment).commit()
}

Let's say this is the class of the child

class InputFieldPresentation: Fragment()
{
    var views: View? = null
    override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
        views = inflater!!.inflate(R.layout.input_field_frag, container, false)
        return views
    }

    override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        ...
    }
    ...
}

Now you can add the children to the father fragment like this

 FatherPresentation:Fragment()
{
  ...

    override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        val fieldFragment= InputFieldPresentation()
        addChildFragment(fieldFragment,R.id.fragmet_field)
    }
...
}

where R.id.fragmet_field is the id of the layout which will contain the fragment.This lyout is inside the father fragment of course. Here is an example

father_fragment.xml:

<LinearLayout android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android"
    >

    ...

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:id="@+id/fragmet_field"
            android:orientation="vertical"
            >
        </LinearLayout>
    ...

    </LinearLayout>

Based on @Chris's function to calculate the mode or related metrics, however using Ken Williams's method to calculate frequencies. This one provides a fix for the case of no modes at all (all elements equally frequent), and some more readable method names.

Mode <- function(x, method = "one", na.rm = FALSE) {
  x <- unlist(x)
  if (na.rm) {
    x <- x[!is.na(x)]
  }

  # Get unique values
  ux <- unique(x)
  n <- length(ux)

  # Get frequencies of all unique values
  frequencies <- tabulate(match(x, ux))
  modes <- frequencies == max(frequencies)

  # Determine number of modes
  nmodes <- sum(modes)
  nmodes <- ifelse(nmodes==n, 0L, nmodes)

  if (method %in% c("one", "mode", "") | is.na(method)) {
    # Return NA if not exactly one mode, else return the mode
    if (nmodes != 1) {
      return(NA)
    } else {
      return(ux[which(modes)])
    }
  } else if (method %in% c("n", "nmodes")) {
    # Return the number of modes
    return(nmodes)
  } else if (method %in% c("all", "modes")) {
    # Return NA if no modes exist, else return all modes
    if (nmodes > 0) {
      return(ux[which(modes)])
    } else {
      return(NA)
    }
  }
  warning("Warning: method not recognised.  Valid methods are 'one'/'mode' [default], 'n'/'nmodes' and 'all'/'modes'")
}

Since it uses Ken's method to calculate frequencies the performance is also optimised, using AkselA's post I benchmarked some of the previous answers as to show how my function is close to Ken's in performance, with the conditionals for the various ouput options causing only minor overhead:

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

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

Implementations of java.util.Set

Its quite easy on computer a you don't need to do anything just make sure both system are on same network if its not internet access(for this you need static ip). Okay now on computer b go to start menu find configuration under oracle folder click Net Configuration Assistant under that folder when window pop up click Local net configuration option it must be third option.

Now click add and click next in next screen it will ask service name here you need to add oracle global database name of computer A(Normally I use oracle86 for my installation) now click next next screen choose protocol normally its tcp click next in host name enter computer A's name you can found that in my computer properties. Click next don't change port untill you have changed that in Computer A click next and choose test connection now here you can check your connection working or not if the error is username and password not correct then click login credential button and fill correct username and password. If its saying unable to reach computer ot target not found than you must add exception in firewall for 1521 port or just disable firewall on computer A.

Use the Instr function

Dim pos As Integer

pos = InStr("find the comma, in the string", ",")

will return 15 in pos

If not found it will return 0

If you need to find the comma with an excel formula you can use the =FIND(",";A1) function.

Notice that if you want to use Instr to find the position of a string case-insensitive use the third parameter of Instr and give it the const vbTextCompare (or just 1 for die-hards).

Dim posOf_A As Integer

posOf_A = InStr(1, "find the comma, in the string", "A", vbTextCompare)

will give you a value of 14.

Note that you have to specify the start position in this case as stated in the specification I linked: The start argument is required if compare is specified.

You can use the fluent API in Eclipse Collections:

        .withKeyValue("a", 1)
        .withKeyValue("b", 2);

Assert.assertEquals(Maps.mutable.with("a", 1, "b", 2), map);

Here's a blog with more detail and examples.

Note: I am a committer for Eclipse Collections.

You can use row_number() to get the row number of the row. It uses the over command - the partition by clause specifies when to restart the numbering and the order by selects what to order the row number on. Even if you added an order by to the end of your query, it would preserve the ordering in the over command when numbering.

select *
from mytable
where row_number() over(partition by Name order by AddressLine) = 1

Maybe it can help
Convert one codepage to another:

    public static string fnStringConverterCodepage(string sText, string sCodepageIn = "ISO-8859-8", string sCodepageOut="ISO-8859-8")
    {
        string sResultado = string.Empty;
        try
        {
            byte[] tempBytes;
            tempBytes = System.Text.Encoding.GetEncoding(sCodepageIn).GetBytes(sText);
            sResultado = System.Text.Encoding.GetEncoding(sCodepageOut).GetString(tempBytes);
        }
        catch (Exception)
        {
            sResultado = "";
        }
        return sResultado;
    }

Usage:

string sMsg = "ERRO: Não foi possivel acessar o servico de Autenticação";
var sOut = fnStringConverterCodepage(sMsg ,"ISO-8859-1","UTF-8"));

Output:

"Não foi possivel acessar o servico de Autenticação"

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.

CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);

Perform a select and use this select query and save to the parameter @IDNUMBER

(SELECT IFNULL
     (CONCAT('LHPL',LPAD(
       (SUBSTRING_INDEX
        (MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
    AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)

And then Insert query will be :

INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES 
(@IDNUMBER, 'EMPLOYEE NAME');

The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.

I had exactly the same problem and found the solution eventually. My query runs like:

$result = mysqli_query($link,'SELECT * FROM clients WHERE ' . $sql_where . ' AND ' . $sql_where2 . ' ORDER BY acconame ASC ');

In order to display the sql command, all I had to do was to create a variable ($resultstring) with the exact same content as my query and then echo it, like this:<?php echo $resultstring = 'SELECT * FROM clients WHERE ' . $sql_where . ' AND ' . $sql_where2 . ' ORDER BY acconame ASC '; ?>

It works!

Just to add to John's answer, echo should be the only one you use to print content to the page.

print is slightly slower. var_dump() and print_r() should only be used to debug.

Also worth mentioning is that print_r() and var_dump() will echo by default, add a second argument to print_r() at least that evaluates to true to get it to return instead, e.g. print_r($array, TRUE).

The difference between echoing and returning are:

• echo: Will immediately print the value to the output.
• returning: Will return the function's output as a string. Useful for logging, etc.

Use a BindingList and set the DataPropertyName-Property of the column.

Try the following:

...
private void BindGrid()
{
    gvFilesOnServer.AutoGenerateColumns = false;

    //create the column programatically
    DataGridViewCell cell = new DataGridViewTextBoxCell();
    DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn()
    {
        CellTemplate = cell, 
        Name = "Value",
        HeaderText = "File Name",
        DataPropertyName = "Value" // Tell the column which property of FileName it should use
     };

    gvFilesOnServer.Columns.Add(colFileName);

    var filelist = GetFileListOnWebServer().ToList();
    var filenamesList = new BindingList<FileName>(filelist); // <-- BindingList

    //Bind BindingList directly to the DataGrid, no need of BindingSource
    gvFilesOnServer.DataSource = filenamesList 
}

I encountered this exact issue when I attempted gem install bundler, and I was confused by all the Python responses (since I was using Ruby). Here was my exact error:

ERROR:  Could not find a valid gem 'bundler' (>= 0), here is why:

My solution: I updated Ruby to the most recent version (2.6.5). Problem solved.

If looking for a higher api level 2.0 and above this will work great

@Override
public void onBackPressed() {
    // Do Here what ever you want do on back press;
}

If looking for android api level upto 1.6.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
     if (keyCode == KeyEvent.KEYCODE_BACK) {
     //preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR
     return true;
     }
     return super.onKeyDown(keyCode, event);    
}

Write above code in your Activity to prevent back button pressed

You can run below commands. I believe this is what you want!

I have built a performance framework that manipulates and graphs millions of datasets, and even then, the javascript calculation latency was on order of tens of milliseconds. Unless you're worried about going over the array size limit, I don't think you have much to worry about.

How would I accomplish the nextsibling and is there an easier way of doing this?

You may use:

tr/td[@class='name']/following-sibling::td

but I'd rather use directly:

tr[td[@class='name'] ='Brand']/td[@class='desc']

This assumes that:

1. The context node, against which the XPath expression is evaluated is the parent of all tr elements -- not shown in your question.

2. Each tr element has only one td with class attribute valued 'name' and only one td with class attribute valued 'desc'.

You can kill the process which is running the container.

With this command you can list the processes related with the docker container:

ps -aux | grep $(docker ps -a | grep container-name | awk '{print $1}')

Now you have the process ids to kill with kill or kill -9.

An option for delegates in C++ that is not otherwise mentioned here is to do it C style using a function ptr and a context argument. This is probably the same pattern that many asking this question are trying to avoid. But, the pattern is portable, efficient, and is usable in embedded and kernel code.

class SomeClass
{
    in someMember;
    int SomeFunc( int);

    static void EventFunc( void* this__, int a, int b, int c)
    {
        SomeClass* this_ = static_cast< SomeClass*>( this__);

        this_->SomeFunc( a );
        this_->someMember = b + c;
    }
};

void ScheduleEvent( void (*delegateFunc)( void*, int, int, int), void* delegateContext);

    ...
    SomeClass* someObject = new SomeObject();
    ...
    ScheduleEvent( SomeClass::EventFunc, someObject);
    ...

Use a common table expression to add grand total row, top 100 is required for order by to work.

With Detail as 
(
    SELECT  top 100 propertyId, SUM(Amount) as TOTAL_COSTS
    FROM MyTable
    WHERE EndDate IS NULL
    GROUP BY propertyId
    ORDER BY TOTAL_COSTS desc
)

Select * from Detail
Union all
Select ' Total ', sum(TOTAL_COSTS) from Detail

Operators first() and take(1) aren't the same.

The first() operator takes an optional predicate function and emits an error notification when no value matched when the source completed.

For example this will emit an error:

import { EMPTY, range } from 'rxjs';
import { first, take } from 'rxjs/operators';

EMPTY.pipe(
  first(),
).subscribe(console.log, err => console.log('Error', err));

... as well as this:

range(1, 5).pipe(
  first(val => val > 6),
).subscribe(console.log, err => console.log('Error', err));

While this will match the first value emitted:

range(1, 5).pipe(
  first(),
).subscribe(console.log, err => console.log('Error', err));

On the other hand take(1) just takes the first value and completes. No further logic is involved.

range(1, 5).pipe(
  take(1),
).subscribe(console.log, err => console.log('Error', err));

Then with empty source Observable it won't emit any error:

EMPTY.pipe(
  take(1),
).subscribe(console.log, err => console.log('Error', err));

Jan 2019: Updated for RxJS 6

As others have mentioned the underlying dict is unordered. However there are OrderedDict objects in python. ( They're built in in recent pythons, or you can use this: http://code.activestate.com/recipes/576693/ ).

I believe that newer pythons json implementations correctly handle the built in OrderedDicts, but I'm not sure (and I don't have easy access to test).

Old pythons simplejson implementations dont handle the OrderedDict objects nicely .. and convert them to regular dicts before outputting them.. but you can overcome this by doing the following:

class OrderedJsonEncoder( simplejson.JSONEncoder ):
   def encode(self,o):
      if isinstance(o,OrderedDict.OrderedDict):
         return "{" + ",".join( [ self.encode(k)+":"+self.encode(v) for (k,v) in o.iteritems() ] ) + "}"
      else:
         return simplejson.JSONEncoder.encode(self, o)

now using this we get:

>>> import OrderedDict
>>> unordered={"id":123,"name":"a_name","timezone":"tz"}
>>> ordered = OrderedDict.OrderedDict( [("id",123), ("name","a_name"), ("timezone","tz")] )
>>> e = OrderedJsonEncoder()
>>> print e.encode( unordered )
{"timezone": "tz", "id": 123, "name": "a_name"}
>>> print e.encode( ordered )
{"id":123,"name":"a_name","timezone":"tz"}

Which is pretty much as desired.

Another alternative would be to specialise the encoder to directly use your row class, and then you'd not need any intermediate dict or UnorderedDict.

dist = sqrt( (x2 - x1)**2 + (y2 - y1)**2 )

As others have pointed out, you can also use the equivalent built-in math.hypot():

dist = math.hypot(x2 - x1, y2 - y1)

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

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

1. $() means: "first evaluate this, and then evaluate the rest of the line".

   Ex :

   echo $(pwd)/myFile.txt
   

   will be interpreted as

   echo /my/path/myFile.txt
   

   On the other hand ${} expands a variable.

   Ex:

   MY_VAR=toto
   echo ${MY_VAR}/myFile.txt
   

   will be interpreted as

   echo toto/myFile.txt
   

2. Why can't I use it as bash$ while ((i=0;i<10;i++)); do echo $i; done

   I'm afraid the answer is just that the bash syntax for while just isn't the same as the syntax for for.

Visit Javascripture ! And go the section readAsText and try the example. You will be able to know how the readAsText function of FileReader works.

    <html>
    <head>
    <script>
      var openFile = function(event) {
        var input = event.target;

        var reader = new FileReader();
        reader.onload = function(){
          var text = reader.result;
          var node = document.getElementById('output');
          node.innerText = text;
          console.log(reader.result.substring(0, 200));
        };
        reader.readAsText(input.files[0]);
      };
    </script>
    </head>
    <body>
    <input type='file' accept='text/plain' onchange='openFile(event)'><br>
    <div id='output'>
    ...
    </div>
    </body>
    </html>

Currently there is no way to apply a css to get your desired result . Why not use libraries like choosen or select2 . These allow you to style the way you want.

If you don want to use third party libraries then you can make a simple un-ordered list and play with some css.Here is thread you could follow

How to convert <select> dropdown into an unordered list using jquery?

So here's my solution.

A simple example for a 3x3 Array. You can keep chaining this to go deeper

Array(3).fill().map(a => Array(3))

Or the following function will generate any level deep you like

f = arr => {
    let str = 'return ', l = arr.length;
    arr.forEach((v, i) => {
        str += i < l-1 ? `Array(${v}).fill().map(a => ` : `Array(${v}` + ')'.repeat(l);
    });
    return Function(str)();
}
f([4,5,6]) // Generates a 4x5x6 Array

http://www.binaryoverdose.com/2017/02/07/Generating-Multidimensional-Arrays-in-JavaScript/

declare @n int = 7,
    @m int = 3;

select 
    case 
        when @n = 1 then
            'SOMETEXT'
    else
        case 
            when @m = 1 then
                'SOMEOTHERTEXT'
            when @m = 2 then
                'SOMEOTHERTEXTGOESHERE'
        end
    end as col1
-- n=1 => returns SOMETEXT regardless of @m
-- n=2 and m=1 => returns SOMEOTHERTEXT
-- n=2 and m=2 => returns SOMEOTHERTEXTGOESHERE
-- n=2 and m>2 => returns null (no else defined for inner case)

I can confirm ckramer that jQuery's ready event works in IE and FireFox. Here's a sample:

<html>
<head>
    <title>Test Page</title>
    <script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
    <script type="text/javascript">
            $(document).ready(function () {
               var d = new Date();
               $('#test').html( "Hi at " + d.toString() );
            });
    </script>
</head>
<body>
    <div id="test"></div>
    <div>
        <a href="http://www.google.com">Go!</a>
    </div>
</body>
</html>

Based on the solution presented by @Layton Everson I developed a counter including hours, minutes and seconds:

var initialSecs = 86400;
var currentSecs = initialSecs;

setTimeout(decrement,1000); 

function decrement() {
   var displayedSecs = currentSecs % 60;
   var displayedMin = Math.floor(currentSecs / 60) % 60;
   var displayedHrs = Math.floor(currentSecs / 60 /60);

    if(displayedMin <= 9) displayedMin = "0" + displayedMin;
    if(displayedSecs <= 9) displayedSecs = "0" + displayedSecs;
    currentSecs--;
    document.getElementById("timerText").innerHTML = displayedHrs + ":" + displayedMin + ":" + displayedSecs;
    if(currentSecs !== -1) setTimeout(decrement,1000);
}

There are two differences between static inner and non static inner classes.

1. In case of declaring member fields and methods, non static inner class cannot have static fields and methods. But, in case of static inner class, can have static and non static fields and method.

2. The instance of non static inner class is created with the reference of object of outer class, in which it has defined, this means it has enclosing instance. But the instance of static inner class is created without the reference of Outer class, which means it does not have enclosing instance.

See this example

class A
{
    class B
    {
        // static int x; not allowed here
    }

    static class C
    {
        static int x; // allowed here
    }
}

class Test
{
    public static void main(String… str)
    {
        A a = new A();

        // Non-Static Inner Class
        // Requires enclosing instance
        A.B obj1 = a.new B(); 

        // Static Inner Class
        // No need for reference of object to the outer class
        A.C obj2 = new A.C(); 
    }
}

I'd recommend Replace in lieu of Substring to avoid string length issues:

REPLACE(CONVERT(varchar(20), (CAST(SUM(table.value) AS money)), 1), '.00', '')

webpack solution

If you got this error while working in React with webpack and HMR.

You need to create template index.html and save it in src folder:

<html>
    <body>
       <div id="root"></root>
    </body>
</html>

Now when we have template with id="root" we need to tell webpack to generate index.html which will mirror our index.html file.

To do that:

plugins: [
    new HtmlWebpackPlugin({
        title: "Application name",
        template: './src/index.html'
    })
],

template property will tell webpack how to build index.html file.

#detail {margin-bottom:5px;}

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

DATETIMEs are not "stored in the following format". They are stored in a binary format.

SELECT CAST(GETDATE() AS BINARY(8))

The display format in the question is independent of storage.

Formatting into a particular display format should be done by your application.

To me, the problem is readability.

A while statement with a true condition tells you nothing about the loop. It makes the job of understanding it much more difficult.

What would be easier to understand out of these two snippets?

do {
  // Imagine a nice chunk of code here
} while(true);

do {
  // Imagine a nice chunk of code here
} while(price < priceAllowedForDiscount);

As of Visual Studio Code Release 1.22 this comes free without the need of an extension.

Shift+Alt+O will take care of you.

Here's what I've learned as I determine the best way to move forward with a couple of my current app projects.

Async Storage (formerly "built-in" to React Native, now moved on its own)

I use AsyncStorage for an in-production app. Storage stays local to the device, is unencrypted (as mentioned in another answer), goes away if you delete the app, but should be saved as part of your device's backups and persists during upgrades (both native upgrades ala TestFlight and code upgrades via CodePush).

Conclusion: Local storage; you provide your own sync/backup solution.

SQLite

Other projects I have worked on have used sqlite3 for app storage. This gives you an SQL-like experience, with compressible databases that can also be transmitted to and from the device. I have not had any experience with syncing them to a back end, but I imagine various libraries exist. There are RN libraries for connecting to SQLite.

Data is stored in your traditional database format with databases, tables, keys, indices, etc. all saved to disk in a binary format. Direct access to the data is available via command line or apps that have SQLite drivers.

Conclusion: Local storage; you supply the sync and backup.

Firebase

Firebase offers, among other things, a real time noSQL database along with a JSON document store (like MongoDB) meant for keeping from 1 to n number of clients synchronized. The docs talk about offline persistence, but only for native code (Swift/Obj-C, Java). Google's own JavaScript option ("Web") which is used by React Native does not provide a cached storage option (see 2/18 update below). The library is written with the assumption that a web browser is going to be connecting, and so there will be a semi-persistent connection. You could probably write a local caching mechanism to supplement the Firebase storage calls, or you could write a bridge between the native libraries and React Native.

Update 2/2018 I have since found React Native Firebase which provides a compatible JavaScript interface to the native iOS and Android libraries (doing what Google probably could/should have done), giving you all the goodies of the native libraries with the bonus of React Native support. With Google's introduction of a JSON document store beside the real-time database, I'm giving Firebase a good second look for some real-time apps I plan to build.

The real-time database is stored as a JSON-like tree that you can edit on the website and import/export pretty simply.

Conclusion: With react-native-firebase, RN gets same benefits as Swift and Java. [/update] Scales well for network-connected devices. Low cost for low utilization. Combines nicely with other Google cloud offerings. Data readily visible and editable from their interface.

Realm

Update 4/2020 MongoDB has acquired Realm and is planning to combine it with MongoDB Stitch (discussed below). This looks very exciting.

Update 9/2020 Having used Realm vs. Stitch: Stitch API's essentially allowed a JS app (React Native or web) to talk directly to the Mongo database instead of going through an API server you build yourself.

Realm was meant to synchronize portions of the database whenever changes were made.

The combination of the two gets a little confusing. The formerly-known-as-Stitch API's still work like your traditional Mongo query and update calls, whereas the newer Realm stuff attaches to objects in code and handles synchronization all by itself... mostly. I'm still working through the right way to do things in one project, which is using SwiftUI, so it's a bit off-topic. But promising and neat nonetheless.

Also a real time object store with automagic network synchronization. They tout themselves as "device first" and the demo video shows how the devices handle sporadic or lossy network connectivity.

They offer a free version of the object store that you host on your own servers or in a cloud solution like AWS or Azure. You can also create in-memory stores that do not persist with the device, device-only stores that do not sync up with the server, read-only server stores, and the full read-write option for synchronization across one or more devices. They have professional and enterprise options that cost more up front per month than Firebase.

Unlike Firebase, all Realm capabilities are supported in React Native and Xamarin, just as they are in Swift/ObjC/Java (native) apps.

Your data is tied to objects in your code. Because they are defined objects, you do have a schema, and version control is a must for code sanity. Direct access is available via GUI tools Realm provides. On-device data files are cross-platform compatible.

Conclusion: Device first, optional synchronization with free and paid plans. All features supported in React Native. Horizontal scaling more expensive than Firebase.

iCloud

I honestly haven't done a lot of playing with this one, but will be doing so in the near future.

If you have a native app that uses CloudKit, you can use CloudKit JS to connect to your app's containers from a web app (or, in our case, React Native). In this scenario, you would probably have a native iOS app and a React Native Android app.

Like Realm, this stores data locally and syncs it to iCloud when possible. There are public stores for your app and private stores for each customer. Customers can even chose to share some of their stores or objects with other users.

I do not know how easy it is to access the raw data; the schemas can be set up on Apple's site.

Conclusion: Great for Apple-targeted apps.

Couchbase

Big name, lots of big companies behind it. There's a Community Edition and Enterprise Edition with the standard support costs.

They've got a tutorial on their site for hooking things up to React Native. I also haven't spent much time on this one, but it looks to be a viable alternative to Realm in terms of functionality. I don't know how easy it is to get to your data outside of your app or any APIs you build.

[Edit: Found an older link that talks about Couchbase and CouchDB, and CouchDB may be yet another option to consider. The two are historically related but presently completely different products. See this comparison.]

Conclusion: Looks to have similar capabilities as Realm. Can be device-only or synced. I need to try it out.

MongoDB

Update 4/2020

Mongo acquired Realm and plans to combine MongoDB Stitch (discussed below) with Realm (discussed above).

I'm using this server side for a piece of the app that uses AsyncStorage locally. I like that everything is stored as JSON objects, making transmission to the client devices very straightforward. In my use case, it's used as a cache between an upstream provider of TV guide data and my client devices.

There is no hard structure to the data, like a schema, so every object is stored as a "document" that is easily searchable, filterable, etc. Similar JSON objects could have additional (but different) attributes or child objects, allowing for a lot of flexibility in how you structure your objects/data.

I have not tried any client to server synchronization features, nor have I used it embedded. React Native code for MongoDB does exist.

Conclusion: Local only NoSQL solution, no obvious sync option like Realm or Firebase.

Update 2/2019

MongoDB has a "product" (or service) called Stitch. Since clients (in the sense of web browsers and phones) shouldn't be talking to MongoDB directly (that's done by code on your server), they created a serverless front-end that your apps can interface with, should you choose to use their hosted solution (Atlas). Their documentation makes it appear that there is a possible sync option.

This writeup from Dec 2018 discusses using React Native, Stitch, and MongoDB in a sample app, with other samples linked in the document (https://www.mongodb.com/blog/post/building-ios-and-android-apps-with-the-mongodb-stitch-react-native-sdk).

Twilio Sync

Another NoSQL option for synchronization is Twilio's Sync. From their site: "Sync lets you manage state across any number of devices in real time at scale without having to handle any backend infrastructure."

I looked at this as an alternative to Firebase for one of the aforementioned projects, especially after talking to both teams. I also like their other communications tools, and have used them for texting updates from a simple web app.

[Edit] I've spent some time with Realm since I originally wrote this. I like how I don't have to write an API to sync the data between the app and the server, similar to Firebase. Serverless functions also look to be really helpful with these two, limiting the amount of backend code I have to write.

I love the flexibility of the MongoDB data store, so that is becoming my choice for the server side of web-based and other connection-required apps.

I found RESTHeart, which creates a very simple, scalable RESTful API to MongoDB. It shouldn't be too hard to build a React (Native) component that reads and writes JSON objects to RESTHeart, which in turn passes them to/from MongoDB.

[Edit] I added info about how the data is stored. Sometimes it's important to know how much work you might be in for during development and testing if you've got to tweak and test the data.

Edits 2/2019 I experimented with several of these options when designing a high-concurrency project this past year (2018). Some of them mention hard and soft concurrency limits in their documentation (Firebase had a hard one at 10,000 connections, I believe, while Twilio's was a soft limit that could be bumped, according to discussions with both teams at AltConf).

If you are designing an app for tens to hundreds of thousands of users, be prepared to scale the data backend accordingly.

Rob R.'s answer was definitely the way to go. I tried copying the ic_launcher.png files from another project and Eclipse still wouldn't read them. Going through the manifest is much quicker and easier.

How about:

ACell.ListObject.DataBodyRange.Rows.Delete

That will keep your table structure and headings, but clear all the data and rows.

EDIT: I'm going to just modify a section of my answer from your previous post, as it does mostly what you want. This leaves just one row:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete
   .DataBodyRange.Rows(1).Specialcells(xlCellTypeConstants).ClearContents
End With

If you want to leave all the rows intact with their formulas and whatnot, just do:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Specialcells(xlCellTypeConstants).ClearContents
End With

Which is close to what @Readify suggested, except it won't clear formulas.

In a functional component this principle also works, it's just a slightly different syntax and way of thinking.

const UploadsWindow = () => {
  // will hold a reference for our real input file
  let inputFile = '';

  // function to trigger our input file click
  const uploadClick = e => {
    e.preventDefault();
    inputFile.click();
    return false;
  };

  return (
    <>
      <input
        type="file"
        name="fileUpload"
        ref={input => {
          // assigns a reference so we can trigger it later
          inputFile = input;
        }}
        multiple
      />

      <a href="#" className="btn" onClick={uploadClick}>
        Add or Drag Attachments Here
      </a>
    </>
  )

}

It may be a little late but you may use my library KResourceLoader to get a resource from your jar:

File resource = getResource("file.txt")

Equality operators: == and !=

The == operator, also known as equality or double equal, will return true if both objects are equal and false if they are not.

"koan" == "koan" # Output: => true

The != operator, also known as inequality, is the opposite of ==. It will return true if both objects are not equal and false if they are equal.

"koan" != "discursive thought" # Output: => true

Note that two arrays with the same elements in a different order are not equal, uppercase and lowercase versions of the same letter are not equal and so on.

When comparing numbers of different types (e.g., integer and float), if their numeric value is the same, == will return true.

2 == 2.0 # Output: => true

equal?

Unlike the == operator which tests if both operands are equal, the equal method checks if the two operands refer to the same object. This is the strictest form of equality in Ruby.

Example: a = "zen" b = "zen"

a.object_id  # Output: => 20139460
b.object_id  # Output :=> 19972120

a.equal? b  # Output: => false

In the example above, we have two strings with the same value. However, they are two distinct objects, with different object IDs. Hence, the equal? method will return false.

Let's try again, only this time b will be a reference to a. Notice that the object ID is the same for both variables, as they point to the same object.

a = "zen"
b = a

a.object_id  # Output: => 18637360
b.object_id  # Output: => 18637360

a.equal? b  # Output: => true

eql?

In the Hash class, the eql? method it is used to test keys for equality. Some background is required to explain this. In the general context of computing, a hash function takes a string (or a file) of any size and generates a string or integer of fixed size called hashcode, commonly referred to as only hash. Some commonly used hashcode types are MD5, SHA-1, and CRC. They are used in encryption algorithms, database indexing, file integrity checking, etc. Some programming languages, such as Ruby, provide a collection type called hash table. Hash tables are dictionary-like collections which store data in pairs, consisting of unique keys and their corresponding values. Under the hood, those keys are stored as hashcodes. Hash tables are commonly referred to as just hashes. Notice how the word hashcan refer to a hashcode or to a hash table. In the context of Ruby programming, the word hash almost always refers to the dictionary-like collection.

Ruby provides a built-in method called hash for generating hashcodes. In the example below, it takes a string and returns a hashcode. Notice how strings with the same value always have the same hashcode, even though they are distinct objects (with different object IDs).

"meditation".hash  # Output: => 1396080688894079547
"meditation".hash  # Output: => 1396080688894079547
"meditation".hash  # Output: => 1396080688894079547

The hash method is implemented in the Kernel module, included in the Object class, which is the default root of all Ruby objects. Some classes such as Symbol and Integer use the default implementation, others like String and Hash provide their own implementations.

Symbol.instance_method(:hash).owner  # Output: => Kernel
Integer.instance_method(:hash).owner # Output: => Kernel

String.instance_method(:hash).owner  # Output: => String
Hash.instance_method(:hash).owner  # Output: => Hash

In Ruby, when we store something in a hash (collection), the object provided as a key (e.g., string or symbol) is converted into and stored as a hashcode. Later, when retrieving an element from the hash (collection), we provide an object as a key, which is converted into a hashcode and compared to the existing keys. If there is a match, the value of the corresponding item is returned. The comparison is made using the eql? method under the hood.

"zen".eql? "zen"    # Output: => true
# is the same as
"zen".hash == "zen".hash # Output: => true

In most cases, the eql? method behaves similarly to the == method. However, there are a few exceptions. For instance, eql? does not perform implicit type conversion when comparing an integer to a float.

2 == 2.0    # Output: => true
2.eql? 2.0    # Output: => false
2.hash == 2.0.hash  # Output: => false

Case equality operator: ===

Many of Ruby's built-in classes, such as String, Range, and Regexp, provide their own implementations of the === operator, also known as case-equality, triple equals or threequals. Because it's implemented differently in each class, it will behave differently depending on the type of object it was called on. Generally, it returns true if the object on the right "belongs to" or "is a member of" the object on the left. For instance, it can be used to test if an object is an instance of a class (or one of its subclasses).

String === "zen"  # Output: => true
Range === (1..2)   # Output: => true
Array === [1,2,3]   # Output: => true
Integer === 2   # Output: => true

The same result can be achieved with other methods which are probably best suited for the job. It's usually better to write code that is easy to read by being as explicit as possible, without sacrificing efficiency and conciseness.

2.is_a? Integer   # Output: => true
2.kind_of? Integer  # Output: => true
2.instance_of? Integer # Output: => false

Notice the last example returned false because integers such as 2 are instances of the Fixnum class, which is a subclass of the Integer class. The ===, is_a? and instance_of? methods return true if the object is an instance of the given class or any subclasses. The instance_of method is stricter and only returns true if the object is an instance of that exact class, not a subclass.

The is_a? and kind_of? methods are implemented in the Kernel module, which is mixed in by the Object class. Both are aliases to the same method. Let's verify:

Kernel.instance_method(:kind_of?) == Kernel.instance_method(:is_a?) # Output: => true

Range Implementation of ===

When the === operator is called on a range object, it returns true if the value on the right falls within the range on the left.

(1..4) === 3  # Output: => true
(1..4) === 2.345 # Output: => true
(1..4) === 6  # Output: => false

("a".."d") === "c" # Output: => true
("a".."d") === "e" # Output: => false

Remember that the === operator invokes the === method of the left-hand object. So (1..4) === 3 is equivalent to (1..4).=== 3. In other words, the class of the left-hand operand will define which implementation of the === method will be called, so the operand positions are not interchangeable.

Regexp Implementation of ===

Returns true if the string on the right matches the regular expression on the left. /zen/ === "practice zazen today" # Output: => true # is the same as "practice zazen today"=~ /zen/

Implicit usage of the === operator on case/when statements

This operator is also used under the hood on case/when statements. That is its most common use.

minutes = 15

case minutes
  when 10..20
    puts "match"
  else
    puts "no match"
end

# Output: match

In the example above, if Ruby had implicitly used the double equal operator (==), the range 10..20 would not be considered equal to an integer such as 15. They match because the triple equal operator (===) is implicitly used in all case/when statements. The code in the example above is equivalent to:

if (10..20) === minutes
  puts "match"
else
  puts "no match"
end

Pattern matching operators: =~ and !~

The =~ (equal-tilde) and !~ (bang-tilde) operators are used to match strings and symbols against regex patterns.

The implementation of the =~ method in the String and Symbol classes expects a regular expression (an instance of the Regexp class) as an argument.

"practice zazen" =~ /zen/   # Output: => 11
"practice zazen" =~ /discursive thought/ # Output: => nil

:zazen =~ /zen/    # Output: => 2
:zazen =~ /discursive thought/  # Output: => nil

The implementation in the Regexp class expects a string or a symbol as an argument.

/zen/ =~ "practice zazen"  # Output: => 11
/zen/ =~ "discursive thought" # Output: => nil

In all implementations, when the string or symbol matches the Regexp pattern, it returns an integer which is the position (index) of the match. If there is no match, it returns nil. Remember that, in Ruby, any integer value is "truthy" and nil is "falsy", so the =~ operator can be used in if statements and ternary operators.

puts "yes" if "zazen" =~ /zen/ # Output: => yes
"zazen" =~ /zen/?"yes":"no" # Output: => yes

Pattern-matching operators are also useful for writing shorter if statements. Example:

if meditation_type == "zazen" || meditation_type == "shikantaza" || meditation_type == "kinhin"
  true
end
Can be rewritten as:
if meditation_type =~ /^(zazen|shikantaza|kinhin)$/
  true
end

The !~ operator is the opposite of =~, it returns true when there is no match and false if there is a match.

Your understanding is correct. However, if we walk through:

• (.*) will swallow the whole string;
• it will need to give back characters so that (\\d+) is satistifed (which is why 0 is captured, and not 3000);
• the last (.*) will then capture the rest.

I am not sure what the original intent of the author was, however.

Background image is not Set Perfect then his css is problem create so his css file change to below code

html {  _x000D_
  background-image: url("example.png");  _x000D_
  background-repeat: no-repeat;  _x000D_
  background-position: 0% 0%;_x000D_
  background-size: 100% 100%;_x000D_
}

%; background-size: 100% 100%;"

You can use GNU date, for example,

$ sec=1267619929
$ date -d "UTC 1970-01-01 $sec secs"

or

$ date -ud @1267619929

Could not figure out what you want, but you need something like this ? :

?def a = { b -> b = 1 }
?bValue = a()
println b // prints 1

Now bValue contains the value of b which is a variable in the closure a. Now you can do anything with bValue Let me know if i have misunderstood your question

Edit: due to post-tag 'oracle', the first two queries become irrelevant, leaving 3rd query for oracle.

For MySQL:

SELECT YEAR(ASOFDATE) FROM PASOFDATE

Editted: In anycase if your date is a String, let's convert it into a proper date format. And select the year out of it.

SELECT YEAR(STR_TO_DATE(ASOFDATE, '%d-%b-%Y')) FROM PSASOFDATE

Since you are trying Toad, can you check the following code:

For Oracle:

SELECT EXTRACT (TO_DATE(YEAR, 'MM/DD/YY') FROM ASOFDATE) FROM PSASOFDATE;

Reference:

void listBox1_MouseDoubleClick(object sender, MouseEventArgs e)
{
    int index = this.listBox1.IndexFromPoint(e.Location);
    if (index != System.Windows.Forms.ListBox.NoMatches)
    {
        MessageBox.Show(index.ToString());
    }
}

This should work...check

Either way works, but many places have coding standards in place that will guide the developer one way or the other. If such a policy is not in place, just follow your heart. One thing, though, it REALLY helps the readability of the code if you do use it. especially if you are not following a naming convention on class-level variable names.

Well, there are important differences between how OneHot Encoding and Label Encoding work :

• Label Encoding will basically switch your String variables to int. In this case, the 1st class found will be coded as 1, the 2nd as 2, ... But this encoding creates an issue.

Let's take the example of a variable Animal = ["Dog", "Cat", "Turtle"].

If you use Label Encoder on it, Animal will be [1, 2, 3]. If you parse it to your machine learning model, it will interpret Dog is closer than Cat, and farther than Turtle (because distance between 1 and 2 is lower than distance between 1 and 3).

Label encoding is actually excellent when you have ordinal variable.

For example, if you have a value Age = ["Child", "Teenager", "Young Adult", "Adult", "Old"],

then using Label Encoding is perfect. Child is closer than Teenager than it is from Young Adult. You have a natural order on your variables

• OneHot Encoding (also done by pd.get_dummies) is the best solution when you have no natural order between your variables.

Let's take back the previous example of Animal = ["Dog", "Cat", "Turtle"].

It will create as much variable as classes you encounter. In my example, it will create 3 binary variables : Dog, Cat and Turtle. Then if you have Animal = "Dog", encoding will make it Dog = 1, Cat = 0, Turtle = 0.

Then you can give this to your model, and he will never interpret that Dog is closer from Cat than from Turtle.

But there are also cons to OneHotEncoding. If you have a categorical variable encountering 50 kind of classes

eg : Dog, Cat, Turtle, Fish, Monkey, ...

then it will create 50 binary variables, which can cause complexity issues. In this case, you can create your own classes and manually change variable

eg : regroup Turtle, Fish, Dolphin, Shark in a same class called Sea Animals and then appy a OneHotEncoding.

Can't you just send to INADDR_BROADCAST? Admittedly, that'll send on all interfaces - but that's rarely a problem.

Otherwise, ioctl and SIOCGIFBRDADDR should get you the address on *nix, and WSAioctl and SIO_GET_BROADCAST_ADDRESS on win32.

Just use the split function. It returns a list, so you can keep the first element:

>>> s1.split(':')
['Username', ' How are you today?']
>>> s1.split(':')[0]
'Username'

Alternatively you could use a for loop as shown in the Groovy Docs:

def map = ['a':1, 'b':2, 'c':3]
for ( e in map ) {
    print "key = ${e.key}, value = ${e.value}"
}

/*
Result:
key = a, value = 1
key = b, value = 2
key = c, value = 3
*/

One benefit of using a for loop as opposed to an each closure is easier debugging, as you cannot hit a break point inside an each closure (when using Netbeans).

Try :

adb shell

 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Just tell composer to use source if available:

composer update --prefer-source

Or:

composer install --prefer-source

Then you will get packages as cloned repositories instead of extracted tarballs, so you can make some changes and commit them back. Of course, assuming you have write/push permissions to the repository and Composer knows about project's repository.

Disclaimer: I think I may answered a little bit different question, but this was what I was looking for when I found this question, so I hope it will be useful to others as well.

If Composer does not know, where the project's repository is, or the project does not have proper composer.json, situation is a bit more complicated, but others answered such scenarios already.

Use LINQ if you can.

  label1.Text =  dataGridView1.Rows.Cast<DataGridViewRow>()
                                   .AsEnumerable()
                                   .Sum(x => int.Parse(x.Cells[1].Value.ToString()))
                                   .ToString();

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

You can get the URL for the profile image using the people.get method of the Google+ API. That does require an extra round trip, but is the most reliable way to get the image.

You technically can also use the URL https://s2.googleusercontent.com/s2/photos/profile/{id}?sz={size} which will then redirect to the final URL. {id} is the Google user ID or one of the old Google Profiles usernames (they still exist for users who had them, but I don't think you can create new ones anymore). {size} is the desired size of the photo in pixels. I'm almost certain this is not a documented, supported feature, so I wouldn't rely on it for anything important as it may go away at anytime without notice. But for quick prototypes or small one-off applications, it may be sufficient.

How about leaving it empty, what is wrong with that?

<form name="form1" id="mainForm" method="post" enctype="multipart/form-data" action="">

</form>

Also, you can omit the action attribute and it will work as expected.

To fix/install Android USB driver on Windows 7/8 32bit/64bit:

1. Connect your Android-powered device to your computer's USB port.
2. Right-click on Computer from your desktop or Windows Explorer, and select Manage.
3. Select Devices in the left pane.
4. Locate and expand Other device in the right pane.
5. Right-click the device name (Nexus 7 / Nexus 5 / Nexus 4) and select Update Driver Software. This will launch the Hardware Update Wizard.
6. Select Browse my computer for driver software and click Next.
7. Click Browse and locate the USB driver folder. (The Google USB Driver is located in <sdk>\extras\google\usb_driver\.)
8. Click Next to install the driver.

If it still doesn't work try changing from MTP to PTP.

By default the grid view will take care, just pass empty data set.

The approach I suggest is a bit verbose but I found it to scale pretty well into complex apps. When you want to show a modal, fire an action describing which modal you'd like to see:

Dispatching an Action to Show the Modal

this.props.dispatch({
  type: 'SHOW_MODAL',
  modalType: 'DELETE_POST',
  modalProps: {
    postId: 42
  }
})

(Strings can be constants of course; I’m using inline strings for simplicity.)

Writing a Reducer to Manage Modal State

Then make sure you have a reducer that just accepts these values:

const initialState = {
  modalType: null,
  modalProps: {}
}

function modal(state = initialState, action) {
  switch (action.type) {
    case 'SHOW_MODAL':
      return {
        modalType: action.modalType,
        modalProps: action.modalProps
      }
    case 'HIDE_MODAL':
      return initialState
    default:
      return state
  }
}

/* .... */

const rootReducer = combineReducers({
  modal,
  /* other reducers */
})

Great! Now, when you dispatch an action, state.modal will update to include the information about the currently visible modal window.

Writing the Root Modal Component

At the root of your component hierarchy, add a <ModalRoot> component that is connected to the Redux store. It will listen to state.modal and display an appropriate modal component, forwarding the props from the state.modal.modalProps.

// These are regular React components we will write soon
import DeletePostModal from './DeletePostModal'
import ConfirmLogoutModal from './ConfirmLogoutModal'

const MODAL_COMPONENTS = {
  'DELETE_POST': DeletePostModal,
  'CONFIRM_LOGOUT': ConfirmLogoutModal,
  /* other modals */
}

const ModalRoot = ({ modalType, modalProps }) => {
  if (!modalType) {
    return <span /> // after React v15 you can return null here
  }

  const SpecificModal = MODAL_COMPONENTS[modalType]
  return <SpecificModal {...modalProps} />
}

export default connect(
  state => state.modal
)(ModalRoot)

What have we done here? ModalRoot reads the current modalType and modalProps from state.modal to which it is connected, and renders a corresponding component such as DeletePostModal or ConfirmLogoutModal. Every modal is a component!

Writing Specific Modal Components

There are no general rules here. They are just React components that can dispatch actions, read something from the store state, and just happen to be modals.

For example, DeletePostModal might look like:

import { deletePost, hideModal } from '../actions'

const DeletePostModal = ({ post, dispatch }) => (
  <div>
    <p>Delete post {post.name}?</p>
    <button onClick={() => {
      dispatch(deletePost(post.id)).then(() => {
        dispatch(hideModal())
      })
    }}>
      Yes
    </button>
    <button onClick={() => dispatch(hideModal())}>
      Nope
    </button>
  </div>
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)

The DeletePostModal is connected to the store so it can display the post title and works like any connected component: it can dispatch actions, including hideModal when it is necessary to hide itself.

Extracting a Presentational Component

It would be awkward to copy-paste the same layout logic for every “specific” modal. But you have components, right? So you can extract a presentational <Modal> component that doesn’t know what particular modals do, but handles how they look.

Then, specific modals such as DeletePostModal can use it for rendering:

import { deletePost, hideModal } from '../actions'
import Modal from './Modal'

const DeletePostModal = ({ post, dispatch }) => (
  <Modal
    dangerText={`Delete post ${post.name}?`}
    onDangerClick={() =>
      dispatch(deletePost(post.id)).then(() => {
        dispatch(hideModal())
      })
    })
  />
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)

It is up to you to come up with a set of props that <Modal> can accept in your application but I would imagine that you might have several kinds of modals (e.g. info modal, confirmation modal, etc), and several styles for them.

Accessibility and Hiding on Click Outside or Escape Key

The last important part about modals is that generally we want to hide them when the user clicks outside or presses Escape.

Instead of giving you advice on implementing this, I suggest that you just don’t implement it yourself. It is hard to get right considering accessibility.

Instead, I would suggest you to use an accessible off-the-shelf modal component such as react-modal. It is completely customizable, you can put anything you want inside of it, but it handles accessibility correctly so that blind people can still use your modal.

You can even wrap react-modal in your own <Modal> that accepts props specific to your applications and generates child buttons or other content. It’s all just components!

Other Approaches

There is more than one way to do it.

Some people don’t like the verbosity of this approach and prefer to have a <Modal> component that they can render right inside their components with a technique called “portals”. Portals let you render a component inside yours while actually it will render at a predetermined place in the DOM, which is very convenient for modals.

In fact react-modal I linked to earlier already does that internally so technically you don’t even need to render it from the top. I still find it nice to decouple the modal I want to show from the component showing it, but you can also use react-modal directly from your components, and skip most of what I wrote above.

I encourage you to consider both approaches, experiment with them, and pick what you find works best for your app and for your team.

Try this

Here is the old DEMO:

EDIT: (Here is a working DEMO with Bootstrap 3 and jQuery 1.8.3)

$(document).ready(function() {
    $('#modal-content').modal('show');
    $('#modal-content').on('shown', function() {
        $("#txtname").focus();
    })
});

Starting bootstrap 3 need to use shown.bs.modal event:

$('#modal-content').on('shown.bs.modal', function() {
    $("#txtname").focus();
})

It's an old question. I would like to answer it using new tools.

Works with python 3 (should work with python 2, but I haven't test it) and PyQt5.

Minimal working example. Copy it to the python shell and get the result.

from PyQt5.QtWidgets import QApplication
app = QApplication([])
screen = app.primaryScreen()
screenshot = screen.grabWindow(QApplication.desktop().winId())
screenshot.save('/tmp/screenshot.png')

In GVIM, The file can be browsed using open / read / write dialog;

:browse {command}

{command} - open / read / write

open - Opens the file read - Appends the file write - SaveAs dialog

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

It might be the standard error. You can redirect it:

... > out.txt 2>&1

In Swift 3.1 I have added this extension to UIView

import Foundation
import UIKit
import CoreGraphics


extension UIView {
    func gradientOfView(withColours: UIColor...) {

        var cgColours = [CGColor]()

        for colour in withColours {
            cgColours.append(colour.cgColor)
        }
        let grad = CAGradientLayer()
        grad.frame = self.bounds
        grad.colors = cgColours
        self.layer.insertSublayer(grad, at: 0)
    }
}

which I then call with

    class OverviewVC: UIViewController {

        override func viewDidLoad() {
            super.viewDidLoad()

            self.view.gradientOfView(withColours: UIColor.red,UIColor.green, UIColor.blue)

        }
}

I also wanted to clarify that if you have complex url parameters to build, you will need to build them manually. ie if your query is example.com/?latlng=-37,147, instead of providing the lat and lng values individually, you will need to build the latlng string externally, then provide it as a parameter, ie:

public interface LocationService {    
    @GET("/example/")
    void getLocation(@Query(value="latlng", encoded=true) String latlng);
}

Note the encoded=true is necessary, otherwise retrofit will encode the comma in the string parameter. Usage:

String latlng = location.getLatitude() + "," + location.getLongitude();
service.getLocation(latlng);

If you need to increase MySQL Connections without MySQL restart do like below

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+
1 row in set (0.00 sec)

mysql> SET GLOBAL max_connections = 150;
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 150   |
+-----------------+-------+
1 row in set (0.00 sec)

These settings will change at MySQL Restart.

For permanent changes add below line in my.cnf and restart MySQL

max_connections = 150

This might look stupid, but check if you haven't already added the folder/files you are trying to ignore to the index before. If you did, it does not matter what you put in your .gitignore file, the folders/files will still be staged.

Prefix is the prefix for url routing. If it's equals to '/' it means it will have no prefix. Then you defined a route with pattern "it should start with /hello".

To create a route for '/' you need to add these lines in your src/Shop/MyShopBundle/Resources/config/routing.yml :

ShopMyShopBundle_homepage:
    pattern:  /
    defaults: { _controller: ShopMyShopBundle:Main:index }

You need ImageMagick and GhostScript

<?php
$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

The [0] means page 1.

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

For the folks who are using Java based Spring configuration:

@Configuration
@ComponentScan(basePackages = "com.domain.sample")
@EnableWebMvc
public class SpringConfig extends WebMvcConfigurerAdapter {
....

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        final MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        final ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        converter.setObjectMapper(objectMapper);
        converters.add(converter);
        super.configureMessageConverters(converters);
    }

....

}

I'm using MappingJackson2HttpMessageConverter - which is from fasterxml.

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.3.1</version>
</dependency>

If you want to use codehaus-jackson mapper, instead use this one MappingJacksonHttpMessageConverter

 <dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>${codehaus.jackson.version}</version>
 </dependency>

A plugin is probably your best option. Look in the wordpress plugins directory or google to see if you can find one. I found the one below and that seemed to work perfect.

https://wordpress.org/plugins/woocommerce-products-filter/

This one seems to do exactly what you are after

eval and exec are the correct solution, and they can be used in a safer manner.

As discussed in Python's reference manual and clearly explained in this tutorial, the eval and exec functions take two extra parameters that allow a user to specify what global and local functions and variables are available.

For example:

public_variable = 10

private_variable = 2

def public_function():
    return "public information"

def private_function():
    return "super sensitive information"

# make a list of safe functions
safe_list = ['public_variable', 'public_function']
safe_dict = dict([ (k, locals().get(k, None)) for k in safe_list ])
# add any needed builtins back in
safe_dict['len'] = len

>>> eval("public_variable+2", {"__builtins__" : None }, safe_dict)
12

>>> eval("private_variable+2", {"__builtins__" : None }, safe_dict)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'private_variable' is not defined

>>> exec("print \"'%s' has %i characters\" % (public_function(), len(public_function()))", {"__builtins__" : None}, safe_dict)
'public information' has 18 characters

>>> exec("print \"'%s' has %i characters\" % (private_function(), len(private_function()))", {"__builtins__" : None}, safe_dict)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'private_function' is not defined

In essence you are defining the namespace in which the code will be executed.

One nice way to break out of several nested loops is to refactor your code into a function:

void foo()
{
    for(unsigned int i=0; i < 50; i++)
    {
        for(unsigned int j=0; j < 50; j++)
        {
            for(unsigned int k=0; k < 50; k++)
            {
                // If condition is true
                return;
            }
        }
    }
}

I have done all the solutions mentionned here. but they didn't work until i have made this one using Jquery :

in my HTML page :

> <div  id="labelid" > </div>

and when i click on a button, i put this in my JS file :

$("#labelid").html("<label>Salam Alaykom</label>");

Just to help other people who encounter this error, the url in <soap:address location="https://some.url"/> had an invalid certificate and caused the error.

How many characters can a type text field store?

According to Documentation You can use maximum of 21,844 characters if the charset is UTF8

If a lot, would I be able to specify length in the db text type field as I would with varchar?

You dont need to specify the length. If you need more character use data types MEDIUMTEXT or LONGTEXT. With VARCHAR, specifieng length is not for Storage requirement, it is only for how the data is retrieved from data base.

You can go to your /var/lib/pgsql/data/pg_hba.conf file and add trust in place of Ident It worked for me.

local   all all trust
host    all 127.0.0.1/32    trust

For further details refer to this issue Ident authentication failed for user

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

This file give you some more hints, for example, keydown.up doesn't work you need keydown.arrowup:

https://github.com/angular/angular/blob/630d93150a58581a0d474ebf1befb5d09b6813c5/modules/angular2/src/platform/browser/browser_adapter.dart

I had the same problem, here's my solution:

I have class MyClass and ArrayList< MyClass > that I want to save to Shared Preferences. At first I've added a method to MyClass that converts it to JSON object:

public JSONObject getJSONObject() {
    JSONObject obj = new JSONObject();
    try {
        obj.put("id", this.id);
        obj.put("name", this.name);
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return obj;
}

Then here's the method for saving object "ArrayList< MyClass > items":

SharedPreferences mPrefs = context.getSharedPreferences("some_name", 0);
    SharedPreferences.Editor editor = mPrefs.edit();

    Set<String> set= new HashSet<String>();
    for (int i = 0; i < items.size(); i++) {
        set.add(items.get(i).getJSONObject().toString());
    }

    editor.putStringSet("some_name", set);
    editor.commit();

And here's the method for retrieving the object:

public static ArrayList<MyClass> loadFromStorage() {
    SharedPreferences mPrefs = context.getSharedPreferences("some_name", 0);

    ArrayList<MyClass> items = new ArrayList<MyClass>();

    Set<String> set = mPrefs.getStringSet("some_name", null);
    if (set != null) {
        for (String s : set) {
            try {
                JSONObject jsonObject = new JSONObject(s);
                Long id = jsonObject.getLong("id"));
                String name = jsonObject.getString("name");
                MyClass myclass = new MyClass(id, name);

                items.add(myclass);

            } catch (JSONException e) {
                e.printStackTrace();
         }
    }
    return items;
}

Note that StringSet in Shared Preferences is available since API 11.

Here I am trying to help you do the job step by step: (this may be the answer to other questions)

1. Go to this address , down the page you can see something like "List of Release Packages". Based on your system and .net framework version choose the right one for you. for example if your want to use .NET Framework 4.6 on a 64-bit Windows, choose this version and download it.
2. Then install the file somewhere on your hard drive, just like any other software.
3. Open Visual studio and your project. Then in solution explorer, right-click on "References" and choose "add Reference...".
4. Click the browse button and choose where you install the previous file and go to .../bin/System.Data.SQLite.dll and click add and then OK buttons.

that is pretty much it. now you can use SQLite in your project. to use it in your project on the code level you may use this below example code:

1. make a connection string:

   string connectionString = @"URI=file:{the location of your sqlite database}";

2. establish a sqlite connection:

   SQLiteConnection theConnection = new SQLiteConnection(connectionString );

3. open the connection:

   theConnection.Open();

4. create a sqlite command:

   SQLiteCommand cmd = new SQLiteCommand(theConnection);

5. Make a command text, or better said your SQLite statement:

   cmd.CommandText = "INSERT INTO table_name(col1, col2) VALUES(val1, val2)";

6. Execute the command

   cmd.ExecuteNonQuery();

that is it.

Keep the h2 at the top, then pull-left on the p and pull-right on the login-box

<div class='container'>
  <div class='hero-unit'>

    <h2>Welcome</h2>

    <div class="pull-left">
      <p>Please log in</p>
    </div>

    <div id='login-box' class='pull-right control-group'>
        <div class='clearfix'>
            <input type='text' placeholder='Username' />
        </div>
        <div class='clearfix'>
            <input type='password' placeholder='Password' />
        </div>
        <button type='button' class='btn btn-primary'>Log in</button>
    </div>

    <div class="clearfix"></div>

  </div>
</div>

the default vertical-align on floated boxes is baseline, so the "Please log in" exactly lines up with the "Username" (check by changing the pull-right to pull-left).

I prefer to label buckets with a numeric formula. If the bucket size is 10 then this labels the buckets 0,1,2,...

=INT(A1/10)

If you put the bucket size 10 in a separate cell you can easily vary it.

If cell B1 contains the bucket (0,1,2,...) and column 6 contains the names Low, Medium, High then this formula converts a bucket to a name:

=INDIRECT(ADDRESS(1+B1,6))

Alternatively, this labels the buckets with the least value in the set, i.e. 0,10,20,...

=10*INT(A1/10)

or this labels them with the range 0-10,10-20,20-30,...

=10*INT(A1/10) & "-" & (10*INT(A1/10)+10)

Yes, python strings are immutable and any modification will result in creating a new string. This is how it's mostly done.

So, go ahead with it.

var value = "" + 5 + 6;
alert(value);

I have a sample program for this:

public class BrowserBackForward {

/**
 * @param args
 * @throws InterruptedException 
 */
public static void main(String[] args) throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://seleniumhq.org/");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    //maximize the window
    driver.manage().window().maximize();

    driver.findElement(By.linkText("Documentation")).click();
    System.out.println(driver.getCurrentUrl());
    driver.navigate().back();
    System.out.println(driver.getCurrentUrl());
    Thread.sleep(30000);
    driver.navigate().forward();
    System.out.println("Forward");
    Thread.sleep(30000);
    driver.navigate().refresh();

}

}

Dim originally (in BASIC) stood for Dimension, as it was used to define the dimensions of an array.

(The original implementation of BASIC was Dartmouth BASIC, which descended from FORTRAN, where DIMENSION is spelled out.)

Nowadays, Dim is used to define any variable, not just arrays, so its meaning is not intuitive anymore.

• How do I convert my results to only hours and minutes
  • The accepted answer only returns days + hours. Minutes are not included.
• To provide a column that has hours and minutes, as hh:mm or x hours y minutes, would require additional calculations and string formatting.

When choosing the "best" approach, a more important consideration than speed might be the maintainability and correctness of your code. If so, SQL_CALC_FOUND_ROWS is preferable because you only need to maintain a single query. Using a single query completely precludes the possibility of a subtle difference between the main and count queries, which may lead to an inaccurate COUNT.

You must use some of the C # conversion systems:

string to boolean: True to true

string str = "True";
bool mybool = System.Convert.ToBoolean(str);

boolean to string: true to True

bool mybool = true;
string str = System.Convert.ToString(mybool);

//or

string str = mybool.ToString();

bool.Parse expects one parameter which in this case is str, even .

Convert.ToBoolean expects one parameter.

bool.TryParse expects two parameters, one entry (str) and one out (result).

If TryParse is true, then the conversion was correct, otherwise an error occurred

string str = "True";
bool MyBool = bool.Parse(str);

//Or

string str = "True";
if(bool.TryParse(str, out bool result))
{
   //Correct conversion
}
else
{
     //Incorrect, an error has occurred
}

Stopping Event Propagation in some particular elements ma y become dangerous as it may prevent other some scripts from running. So check whether the triggering is from the excluded area from inside the function.

$(document).on('click', function(event) {
  if (!$(event.target).closest('#menucontainer').length) {
    // Hide the menus.
  }
});

Here function is initiated when clicking on document, but it excludes triggering from #menucontainer. For details https://css-tricks.com/dangers-stopping-event-propagation/

This parameter is just about whether you are going to use complex html into the tooltip. Set it to true and then hit the html into the title attribute of the tag.

See this fiddle here - I've set the html attribute to true through the data-html="true" in the <a> tag and then just added in the html ad hoc as an example.

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

@html.label and @html.textbox are use when you want bind it to your model in a easy way...which cannot be achieve by input etc. in one line

Look into python wheels to solve your problem. The best part of python wheels is that they let you install C extensions with no compilers. I just installed numpy and scipy using pip in a clean python install and they both worked fine.

Update 2019

Why not use an input-group?

<div class="input-group col-md-4">
      <input class="form-control py-2" type="search" value="search" id="example-search-input">
      <span class="input-group-append">
        <button class="btn btn-outline-secondary" type="button">
            <i class="fa fa-search"></i>
        </button>
      </span>
</div>

And, you can make it appear inside the input using the border utils...

        <div class="input-group col-md-4">
            <input class="form-control py-2 border-right-0 border" type="search" value="search" id="example-search-input">
            <span class="input-group-append">
              <button class="btn btn-outline-secondary border-left-0 border" type="button">
                    <i class="fa fa-search"></i>
              </button>
            </span>
        </div>

Or, using a input-group-text w/o the gray background so the icon appears inside the input...

        <div class="input-group">
            <input class="form-control py-2 border-right-0 border" type="search" value="search" id="example-search-input">
            <span class="input-group-append">
                <div class="input-group-text bg-transparent"><i class="fa fa-search"></i></div>
            </span>
        </div>

Alternately, you can use the grid (row>col-) with no gutter spacing:

<div class="row no-gutters">
     <div class="col">
          <input class="form-control border-secondary border-right-0 rounded-0" type="search" value="search" id="example-search-input4">
     </div>
     <div class="col-auto">
          <button class="btn btn-outline-secondary border-left-0 rounded-0 rounded-right" type="button">
             <i class="fa fa-search"></i>
          </button>
     </div>
</div>

Or, prepend the icon like this...

<div class="input-group">
  <span class="input-group-prepend">
    <div class="input-group-text bg-transparent border-right-0">
      <i class="fa fa-search"></i>
    </div>
  </span>
  <input class="form-control py-2 border-left-0 border" type="search" value="..." id="example-search-input" />
  <span class="input-group-append">
    <button class="btn btn-outline-secondary border-left-0 border" type="button">
     Search
    </button>
  </span>
</div>

Normally I try to do whatever I can to avoid the use of cursors, but the following query will get you everything you need:

--Declare/Set required variables
DECLARE @vchDynamicDatabaseName AS VARCHAR(MAX),
        @vchDynamicQuery As VARCHAR(MAX),
        @DatabasesCursor CURSOR

SET @DatabasesCursor = Cursor FOR

--Select * useful databases on the server
SELECT name 
FROM sys.databases 
WHERE database_id > 4 
ORDER by name

--Open the Cursor based on the previous select
OPEN @DatabasesCursor
FETCH NEXT FROM @DatabasesCursor INTO @vchDynamicDatabaseName
WHILE @@FETCH_STATUS = 0
   BEGIN

   --Insert the select statement into @DynamicQuery 
   --This query will select the Database name, all tables/views and their columns (in a comma delimited field)
   SET @vchDynamicQuery =
   ('SELECT ''' + @vchDynamicDatabaseName + ''' AS ''Database_Name'',
          B.table_name AS ''Table Name'',
         STUFF((SELECT '', '' + A.column_name
               FROM ' + @vchDynamicDatabaseName + '.INFORMATION_SCHEMA.COLUMNS A
               WHERE A.Table_name = B.Table_Name
               FOR XML PATH(''''),TYPE).value(''(./text())[1]'',''NVARCHAR(MAX)'')
               , 1, 2, '''') AS ''Columns''
   FROM ' + @vchDynamicDatabaseName + '.INFORMATION_SCHEMA.COLUMNS B
   WHERE B.TABLE_NAME LIKE ''%%''
         AND B.COLUMN_NAME LIKE ''%%''
   GROUP BY B.Table_Name
   Order BY 1 ASC')

   --Print @vchDynamicQuery
   EXEC(@vchDynamicQuery)

   FETCH NEXT FROM @DatabasesCursor INTO @vchDynamicDatabaseName
END
CLOSE @DatabasesCursor
DEALLOCATE @DatabasesCursor
GO

I added a where clause in the main query (ex: B.TABLE_NAME LIKE ''%%'' AND B.COLUMN_NAME LIKE ''%%'') so that you can search for specific tables and/or columns if you want to.

Use isinstance, nothing else:

if isinstance(x, pd.DataFrame):
    ... # do something

PEP8 says explicitly that isinstance is the preferred way to check types

No:  type(x) is pd.DataFrame
No:  type(x) == pd.DataFrame
Yes: isinstance(x, pd.DataFrame)

And don't even think about

if obj.__class__.__name__ = 'DataFrame':
    expect_problems_some_day()

isinstance handles inheritance (see What are the differences between type() and isinstance()?). For example, it will tell you if a variable is a string (either str or unicode), because they derive from basestring)

if isinstance(obj, basestring):
    i_am_string(obj)

Specifically for pandas DataFrame objects:

import pandas as pd
isinstance(var, pd.DataFrame)

If that's the case then why don't you consider using a regular Array, initialize the capacity and put objects at the index you want.

Object[] list = new Object[10];

list[0] = object1;
list[2] = object3;
list[1] = object2;

Using fairly simple code:

int i;
int value;
int n;
char ch;

/* Skip i==0 because that will be the program name */
for (i=1; i<argc; i++) {
    n = sscanf(argv[i], "%d%c", &value, &ch);

    if (n != 1) {
        /* sscanf didn't find a number to convert, so it wasn't a number */
    }
    else {
        /* It was */
    }
}

I assume "direction" is "ASC" or "DESC" and dt contains a column named "colName"

public static DataTable resort(DataTable dt, string colName, string direction)
{
    DataTable dtOut = null;
    dt.DefaultView.Sort = colName + " " + direction;
    dtOut = dt.DefaultView.ToTable();
    return dtOut;
}

OR without creating dtOut

public static DataTable resort(DataTable dt, string colName, string direction)
{
    dt.DefaultView.Sort = colName + " " + direction;
    dt = dt.DefaultView.ToTable();
    return dt;
}

This may not be best answer but, I had to initialize app with admin and firebase like below. I use admin for it's own purposes and firebase as well.

const firebase = require("firebase");
const admin = require("firebase-admin");

admin.initializeApp(functions.config().firebase);
firebase.initializeApp(functions.config().firebase);
// Get the Auth service for the default app
var authService = firebase.auth();

 function createUserWithEmailAndPassword(request, response) {
        const email = request.query.email;
        const password = request.query.password;
        if (!email) {
            response.send("query.email is required.");
            return;
        }
        if (!password) {
            response.send("query.password is required.");
            return;
        }
        return authService.createUserWithEmailAndPassword(email, password)
            .then(success => {
                let responseJson = JSON.stringify(success);
                console.log("createUserWithEmailAndPassword.responseJson", responseJson);
                response.send(responseJson);
            })
            .catch(error => {
                let errorJson = JSON.stringify(error);
                console.log("createUserWithEmailAndPassword.errorJson", errorJson);
                response.send(errorJson);
            });
    }

C99 quotes

This answer aims to quote and explain the relevant parts of the C99 N1256 standard draft.

Definition of declarator

The term declarator will come up a lot, so let's understand it.

From the language grammar, we find that the following underline characters are declarators:

int f(int x, int y);
    ^^^^^^^^^^^^^^^

int f(int x, int y) { return x + y; }
    ^^^^^^^^^^^^^^^

int f();
    ^^^

int f(x, y) int x; int y; { return x + y; }
    ^^^^^^^

Declarators are part of both function declarations and definitions.

There are 2 types of declarators:

• parameter type list
• identifier list

Parameter type list

Declarations look like:

int f(int x, int y);

Definitions look like:

int f(int x, int y) { return x + y; }

It is called parameter type list because we must give the type of each parameter.

Identifier list

Definitions look like:

int f(x, y)
    int x;
    int y;
{ return x + y; }

Declarations look like:

int g();

We cannot declare a function with a non-empty identifier list:

int g(x, y);

because 6.7.5.3 "Function declarators (including prototypes)" says:

3 An identifier list in a function declarator that is not part of a definition of that function shall be empty.

It is called identifier list because we only give the identifiers x and y on f(x, y), types come after.

This is an older method, and shouldn't be used anymore. 6.11.6 Function declarators says:

1 The use of function declarators with empty parentheses (not prototype-format parameter type declarators) is an obsolescent feature.

and the Introduction explains what is an obsolescent feature:

Certain features are obsolescent, which means that they may be considered for withdrawal in future revisions of this International Standard. They are retained because of their widespread use, but their use in new implementations (for implementation features) or new programs (for language [6.11] or library features [7.26]) is discouraged

f() vs f(void) for declarations

When you write just:

void f();

it is necessarily an identifier list declaration, because 6.7.5 "Declarators" says defines the grammar as:

direct-declarator:
    [...]
    direct-declarator ( parameter-type-list )
    direct-declarator ( identifier-list_opt )

so only the identifier-list version can be empty because it is optional (_opt).

direct-declarator is the only grammar node that defines the parenthesis (...) part of the declarator.

So how do we disambiguate and use the better parameter type list without parameters? 6.7.5.3 Function declarators (including prototypes) says:

10 The special case of an unnamed parameter of type void as the only item in the list specifies that the function has no parameters.

So:

void f(void);

is the way.

This is a magic syntax explicitly allowed, since we cannot use a void type argument in any other way:

void f(void v);
void f(int i, void);
void f(void, int);

What can happen if I use an f() declaration?

Maybe the code will compile just fine: 6.7.5.3 Function declarators (including prototypes):

14 The empty list in a function declarator that is not part of a definition of that function specifies that no information about the number or types of the parameters is supplied.

So you can get away with:

void f();
void f(int x) {}

Other times, UB can creep up (and if you are lucky the compiler will tell you), and you will have a hard time figuring out why:

void f();
void f(float x) {}

See: Why does an empty declaration work for definitions with int arguments but not for float arguments?

f() and f(void) for definitions

f() {}

vs

f(void) {}

are similar, but not identical.

6.7.5.3 Function declarators (including prototypes) says:

14 An empty list in a function declarator that is part of a definition of that function specifies that the function has no parameters.

which looks similar to the description of f(void).

But still... it seems that:

int f() { return 0; }
int main(void) { f(1); }

is conforming undefined behavior, while:

int f(void) { return 0; }
int main(void) { f(1); }

is non conforming as discussed at: Why does gcc allow arguments to be passed to a function defined to be with no arguments?

TODO understand exactly why. Has to do with being a prototype or not. Define prototype.

1. Picasso allows for hassle-free image loading in your application—often in one line of code!

Use Gradle:

implementation 'com.squareup.picasso:picasso:(insert latest version)'

Just one line of code!

Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);

2. Glide An image loading and caching library for Android focused on smooth scrolling

Use Gradle:

repositories {
  mavenCentral() 
  google()
}

dependencies {
   implementation 'com.github.bumptech.glide:glide:4.11.0'
   annotationProcessor 'com.github.bumptech.glide:compiler4.11.0'
}

// For a simple view:

  Glide.with(this).load("http://i.imgur.com/DvpvklR.png").into(imageView);

3. fresco is a powerful system for displaying images in Android applications.Fresco takes care of image loading and display, so you don't have to.

Getting Started with Fresco

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

compile function -

1. is called before the controller and link function.
2. In compile function, you have the original template DOM so you can make changes on original DOM before AngularJS creates an instance of it and before a scope is created
3. ng-repeat is perfect example - original syntax is template element, the repeated elements in HTML are instances
4. There can be multiple element instances and only one template element
5. Scope is not available yet
6. Compile function can return function and object
7. returning a (post-link) function - is equivalent to registering the linking function via the link property of the config object when the compile function is empty.
8. returning an object with function(s) registered via pre and post properties - allows you to control when a linking function should be called during the linking phase. See info about pre-linking and post-linking functions below.

syntax

function compile(tElement, tAttrs, transclude) { ... }

controller

1. called after the compile function
2. scope is available here
3. can be accessed by other directives (see require attribute)

pre - link

1. The link function is responsible for registering DOM listeners as well as updating the DOM. It is executed after the template has been cloned. This is where most of the directive logic will be put.

2. You can update the dom in the controller using angular.element but this is not recommended as the element is provided in the link function

3. Pre-link function is used to implement logic that runs when angular js has already compiled the child elements but before any of the child element's post link have been called

post-link

1. directive that only has link function, angular treats the function as a post link

2. post will be executed after compile, controller and pre-link funciton, so that's why this is considered the safest and default place to add your directive logic

void foo() {
  /* do some stuff */
  if (!condition) {
    return;
  }
}

You can just use the return keyword just like you would in any other function.

If you know the (maximum) number of rows and columns beforehand, you can use resize() to initialize a vector of vectors and then modify (and access) elements with operator[]. Example:

int no_of_cols = 5;
int no_of_rows = 10;
int initial_value = 0;

std::vector<std::vector<int>> matrix;
matrix.resize(no_of_rows, std::vector<int>(no_of_cols, initial_value));

// Read from matrix.
int value = matrix[1][2];

// Save to matrix.
matrix[3][1] = 5;

Another possibility is to use just one vector and split the id in several variables, access like vector[(row * columns) + column].

use this polyfill https://github.com/UziTech/js-date-format

var d = new Date("1/1/2014 10:00 am");
d.format("DDDD 'the' DS 'of' MMMM YYYY h:mm TT");
//output: Wednesday the 1st of January 2014 10:00 AM

whats actually wrong with:

input { border: 1px solid #f00; }

do you only want it on inputs with errors? in that case give the input a class of error...

input.error { border: 1px solid #f00; }

try this code, it will work for all version of URLs like

• website.com
• www.website.com
• http://website.com

• http://www.website.com

  RewriteCond %{HTTPS} off
  RewriteCond %{HTTPS_HOST} !^www.website.com$ [NC]
  RewriteRule ^(.*)$ https://www.website.com/$1 [L,R=301]
  

stdclass is a way in which the php avoid stopping interpreting the script when there is some data must be put in a class , but unfortunately this class was not defined

Example :

 return $statement->fetchAll(PDO::FETCH_CLASS  , 'Tasks');

Here the data will be put in the predefined 'Tasks' . But, if we did the code as this :

 return $statement->fetchAll(PDO::FETCH_CLASS );

then the php will put the results in stdclass .

simply php says that : look , we have a good KIDS[Objects] Here but without Parents . So , we will send them to a infant child Care Home stdclass :)

using jquery without prototype, update the js code to

$( ".stars" ).each(function() { 
    // Get the value
    var val = $(this).data("rating");
    // Make sure that the value is in 0 - 5 range, multiply to get width
    var size = Math.max(0, (Math.min(5, val))) * 16;
    // Create stars holder
    var $span = $('<span />').width(size);
    // Replace the numerical value with stars
    $(this).html($span);
});

I also added a data attribute by the name of data-rating in the span.

<span class="stars" data-rating="4" ></span>

To not include the grouping column:

df %>%
 group_split(g, keep = FALSE)

It manages them because int and long are sibling class definitions. They have appropriate methods for +, -, *, /, etc., that will produce results of the appropriate class.

For example

>>> a=1<<30
>>> type(a)
<type 'int'>
>>> b=a*2
>>> type(b)
<type 'long'>

In this case, the class int has a __mul__ method (the one that implements *) which creates a long result when required.

You can do something like this to disable submit button when loading a new page with the same form:

$("#btnConfirm").bind("click", function (e) {
  $("#btnConfirm ").css("pointer-events", "none");
});

The submit button could look like this:

<input
    type="submit"
    name="ACMS_POST_Form_Confirm"
    value="confirm"
    id="btnConfirm"
/>

I was trying to display borders on an empty cell in an HTML table. My old trick of using non-breaking space in empty cells was not working from xslt. I used line break with the same effect. I mention this just in case the reason you were trying to use the non-breaking space was to give some content to an 'empty' table cell in order to turn on the cell borders.

<br/>

you just need to add a default constructor to your class to look like this:

class name {
  public:
    string first;
    string last;

  name() {
  }

  name(string a, string b){
    first = a;
    last = b;
  }
};

The simplest way to see ram usage if you have RDP access / console access would be just launch task manager - click processes - show processes from all users, sort by RAM - This will give you SQL's usage.

As was mentioned above, to decrease the size (which will take effect immediately, no restart required) launch sql management studio, click the server, properties - memory and decrease the max. There's no exactly perfect number, but make sure the server has ram free for other tasks.

The answers about perfmon are correct and should be used, but they aren't as obvious a method as task manager IMHO.

do the client machines have python loaded? if so, I'm doing this with psexec

On my local machine, I use subprocess in my .py file to call a command line.

import subprocess
subprocess.call("psexec {server} -c {}") 

the -c copies the file to the server so i can run any executable file (which in your case could be a .bat full of connection tests or your .py file from above).

Android already provides a version-aware approach of database management. This approach has been leveraged in the BARACUS framework for Android applications.

It enables you to manage the database along the entire version lifecycle of an app, beeing able to update the sqlite database from any prior version to the current one.

Also, it allows you to run hot-backups and hot-recovery of the SQLite.

I am not 100% sure, but a hot-recovery for a specific device may enable you to ship a prepared database in your app. But I am not sure about the database binary format which might be specific to certain devices, vendors or device generations.

Since the stuff is Apache License 2, feel free to reuse any part of the code, which can be found on github

EDIT :

If you only want to ship data, you might consider instantiating and persisting POJOs at the applications first start. BARACUS got a built-in support to this (Built-in key value store for configuration infos, e.g. "APP_FIRST_RUN" plus a after-context-bootstrap hook in order to run post-launch operations on the context). This enables you to have tight coupled data shipped with your app; in most cases this fitted to my use cases.

You should be using SqlConnection.State

e.g,

using System.Data;

if (myConnection != null && myConnection.State == ConnectionState.Closed)
{
   // do something
   // ...
}

I faced the same error. When I installed Unity Framework for Dependency Injection the new references of the Http and HttpFormatter has been added in my configuration. So here are the steps I followed.

I ran following command on nuGet Package Manager Console: PM> Install-Package Microsoft.ASPNet.WebAPI -pre

And added physical reference to the dll with version 5.0

For me, my Eclipse installation was hosed - I think because I'd installed struts. After trying a dozen remedies for this error, I re-installed Eclipse, made a new workspace and it was OK. Using Kepler-64-Windows, Tomcat 7, Windows 7.

Here's a C# method to do this. Remember to add your own error handling - this mostly assumes that things work for the sake of brevity. It's 4.0+ framework only, but that's mostly because of the optional worksheetNumber parameter. You can overload the method if you need to support earlier versions.

static void ConvertExcelToCsv(string excelFilePath, string csvOutputFile, int worksheetNumber = 1) {
   if (!File.Exists(excelFilePath)) throw new FileNotFoundException(excelFilePath);
   if (File.Exists(csvOutputFile)) throw new ArgumentException("File exists: " + csvOutputFile);

   // connection string
   var cnnStr = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0;IMEX=1;HDR=NO\"", excelFilePath);
   var cnn = new OleDbConnection(cnnStr);

   // get schema, then data
   var dt = new DataTable();
   try {
      cnn.Open();
      var schemaTable = cnn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
      if (schemaTable.Rows.Count < worksheetNumber) throw new ArgumentException("The worksheet number provided cannot be found in the spreadsheet");
      string worksheet = schemaTable.Rows[worksheetNumber - 1]["table_name"].ToString().Replace("'", "");
      string sql = String.Format("select * from [{0}]", worksheet);
      var da = new OleDbDataAdapter(sql, cnn);
      da.Fill(dt);
   }
   catch (Exception e) {
      // ???
      throw e;
   }
   finally {
      // free resources
      cnn.Close();
   }

   // write out CSV data
   using (var wtr = new StreamWriter(csvOutputFile)) {
      foreach (DataRow row in dt.Rows) {
         bool firstLine = true;
         foreach (DataColumn col in dt.Columns) {
            if (!firstLine) { wtr.Write(","); } else { firstLine = false; }
            var data = row[col.ColumnName].ToString().Replace("\"", "\"\"");
            wtr.Write(String.Format("\"{0}\"", data));
         }
         wtr.WriteLine();
      }
   }
}

You may use any of these 2 variants:

/^[A-Z]+$/i
/^[A-Za-z]+$/

to match an input string of ASCII alphabets.

• [A-Za-z] will match all the alphabets (both lowercase and uppercase).
• ^ and $ will make sure that nothing but these alphabets will be matched.

Code:

preg_match('/^[A-Z]+$/i', "abcAbc^Xyz", $m);
var_dump($m);

Output:

array(0) {
}

Test case is for OP's comment that he wants to match only if there are 1 or more alphabets present in the input. As you can see in the test case that matches failed because there was ^ in the input string abcAbc^Xyz.

Note: Please note that the above answer only matches ASCII alphabets and doesn't match Unicode characters. If you want to match Unicode letters then use:

/^\p{L}+$/u

Here, \p{L} matches any kind of letter from any language

I found part of the solution. Images now have metadata that specify the orientation of the photo. There is a new CSS spec for image-orientation.

Just add this to your CSS:

img {
    image-orientation: from-image;
}

According to the spec as of Jan 25 2016, Firefox and iOS Safari (behind a prefix) are the only browsers that support this. I'm seeing issues with Safari and Chrome still. However, mobile Safari seems to natively support orientation without the CSS tag.

I suppose we'll have to wait and see if browsers wills start supporting image-orientation.

For document references, not collections, you need:

// when you know the 'id'

this.afs.doc(`items/${id}`)
  .snapshotChanges().pipe(
    map((doc: any) => {
      const data = doc.payload.data();
      const id = doc.payload.id;
      return { id, ...data };
    });

as .valueChanges({ idField: 'id'}); will not work here. I assume it was not implemented since generally you search for a document by the id...

well, it should be

git stash save
git checkout branch
// do something
git checkout oldbranch
git stash pop

While it doesn't auto generate, one way to generate new migrations on a change to a model is: (assuming that you're using the stock sequelize-cli file structure where migrations, and models are on the same level)

1. (Same as Manuel Bieh's suggestion, but using a require instead of an import) In your migration file (if you don't have one, you can generate one by doing "sequelize migration:create") have the following code:

   'use strict';
   var models = require("../models/index.js")
   module.exports = {
     up: function(queryInterface, Sequelize) {
       return queryInterface.createTable(models.User.tableName, 
         models.User.attributes);
     },
     down: function(queryInterface, Sequelize) {
       return queryInterface.dropTable('Users');
     }
   };
   

2. Make a change to the User model.

3. Delete table from database.
4. Undo all migrations: sequelize db:migrate:undo:all
5. Re-migrate to have changes saved in db. sequelize db:migrate

The best way is to use the following code:

<a href="<?php echo base_url() ?>directory_name/filename.php">Link</a>

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

This is not the most efficient way to do it, but it's easier to read if you are not familiar with log maths, and should be fast enough for most scenarios.

string[] sizes = { "B", "KB", "MB", "GB", "TB" };
double len = new FileInfo(filename).Length;
int order = 0;
while (len >= 1024 && order < sizes.Length - 1) {
    order++;
    len = len/1024;
}

// Adjust the format string to your preferences. For example "{0:0.#}{1}" would
// show a single decimal place, and no space.
string result = String.Format("{0:0.##} {1}", len, sizes[order]);

As also noted by John Szakmeister and VasiliNovikov, the shortest command to get the full diff from master's perspective on your branch is:

git diff master...

This uses your local copy of master.

To compare a specific file use:

git diff master... filepath

Output example:

in my webpack.config.js (Version 1,2,3) file, I have

function isExternal(module) {
  var context = module.context;

  if (typeof context !== 'string') {
    return false;
  }

  return context.indexOf('node_modules') !== -1;
}

in my plugins array

plugins: [
  new CommonsChunkPlugin({
    name: 'vendors',
    minChunks: function(module) {
      return isExternal(module);
    }
  }),
  // Other plugins
]

Now I have a file that only adds 3rd party libs to one file as required.

If you want get more granular where you separate your vendors and entry point files:

plugins: [
  new CommonsChunkPlugin({
    name: 'common',
    minChunks: function(module, count) {
      return !isExternal(module) && count >= 2; // adjustable
    }
  }),
  new CommonsChunkPlugin({
    name: 'vendors',
    chunks: ['common'],
    // or if you have an key value object for your entries
    // chunks: Object.keys(entry).concat('common')
    minChunks: function(module) {
      return isExternal(module);
    }
  })
]

Note that the order of the plugins matters a lot.

Also, this is going to change in version 4. When that's official, I update this answer.

Update: indexOf search change for windows users

Hope this easy one liner helps:

cols_as_np = df[df.columns[1:]].to_numpy()

This code will verify the json independently of param object order.

var isEqualsJson = (obj1,obj2)=>{
    keys1 = Object.keys(obj1);
    keys2 = Object.keys(obj2);

    //return true when the two json has same length and all the properties has same value key by key
    return keys1.length === keys2.length && Object.keys(obj1).every(key=>obj1[key]==obj2[key]);
}

var obj1 = {a:1,b:2,c:3};
var obj2 = {a:1,b:2,c:3}; 

console.log("json is equals: "+ isEqualsJson(obj1,obj2));
alert("json is equals: "+ isEqualsJson(obj1,obj2));

If linking to the shell Lightweight API (shlwapi.dll) is ok for you, you can use the PathIsDirectory function

If you want to quit without saving in Vim and have Vim return a non-zero exit code, you can use :cq.

I use this all the time because I can't be bothered to pinky shift for !. I often pipe things to Vim which don't need to be saved in a file. We also have an odd SVN wrapper at work which must be exited with a non-zero value in order to abort a checkin.
