You can't but I don't think you miss anything.

Because you call sqlite always in process, it almost doesn't matter in performance whether you execute 1 insert statement or 100 insert statements. The commit however takes a lot of time so put those 100 inserts inside a transaction.

Sqlite is much faster when you use parameterized queries (far less parsing needed) so I wouldn't concatenate big statements like this:

insert into mytable (col1, col2)
select 'a','b'
union 
select 'c','d'
union ...

They need to be parsed again and again because every concatenated statement is different.

Here's the simplest, most robust, and scalable solution to get tabs on the bottom of the screen.

1. In your vertical LinearLayout, put the FrameLayout above the TabWidget
2. Set layout_height to wrap_content on both FrameLayout and TabWidget
3. Set FrameLayout's android:layout_weight="1"
4. Set TabWidget's android:layout_weight="0" (0 is default, but for emphasis, readability, etc)
5. Set TabWidget's android:layout_marginBottom="-4dp" (to remove the bottom divider)

Full code:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="5dp"
            android:layout_weight="1"/>

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0"
            android:layout_marginBottom="-4dp"/>

    </LinearLayout>

</TabHost>

repartition - it's recommended to use it while increasing the number of partitions, because it involve shuffling of all the data.

coalesce - it's is recommended to use it while reducing the number of partitions. For example if you have 3 partitions and you want to reduce it to 2, coalesce will move the 3rd partition data to partition 1 and 2. Partition 1 and 2 will remains in the same container. On the other hand, repartition will shuffle data in all the partitions, therefore the network usage between the executors will be high and it will impacts the performance.

coalesce performs better than repartition while reducing the number of partitions.

If you really don't like the Terminal here is the GUI way to do dkamins is telling you :

1) Go to your user home directory (ludo would be mine) and from the File menu choose Get Info cmdI in the inspector :

2) By alt/option clicking on the [+] sign add the _www group and set it's permission to read-only :

• Thus consider (good practice) not storing personnal information at the root of your user home folder (& hard disk) !
• You may skip this step if the **everyone** group has **read-only** permission but since AirDrop the **/Public/Drop Box** folder is mostly useless...

3) Show the Get Info inspector of your user Sites folder and reproduce step 2 then from the gear action sub-menu choose Apply to enclosed Items... :

Voilà 3 steps and the GUI only way...

Go to Phone Settings --> Developer Options --> Simulate Secondary Displays and turn it to None. If you don't see Developer Options in the settings menu (it should be at the bottom, go Settings ==> About phone and tap on the Build number a lot of times)

Some ORM's or frameworks use a different naming convention for foreign keys than the default FK_[parent table]_[referenced table]_[referencing field], because they can be altered.

Laravel for example uses [parent table]_[referencing field]_foreign as naming convention. You can show the names of the foreign keys by using this query, as shown here:

SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE 
WHERE REFERENCED_TABLE_SCHEMA = '<database>' AND REFERENCED_TABLE_NAME = '<table>';

Then remove the foreign key by running the before mentioned DROP FOREIGN KEY query and its proper name.

I had the JSONwebtoken pod installed and that was causing issues. I needed to delete the CommonCrypto folder that is in the JSONWebtoken pod folder. Here is a ->link<- explaining the issue. This started happening in Xcode 10.

It is simple,for Example

-(void)applicationWillEnterForeground:(UIApplication *)application {

    NSLog(@"%s", __PRETTY_FUNCTION__);

}

Output: -[AppDelegate applicationWillEnterForeground:]

The special thing about iterators is that they provide the glue between algorithms and containers. For generic code, the recommendation would be to use a combination of STL algorithms (e.g. find, sort, remove, copy) etc. that carries out the computation that you have in mind on your data structure (vector, list, map etc.), and to supply that algorithm with iterators into your container.

Your particular example could be written as a combination of the for_each algorithm and the vector container (see option 3) below), but it's only one out of four distinct ways to iterate over a std::vector:

1) index-based iteration

for (std::size_t i = 0; i != v.size(); ++i) {
    // access element as v[i]

    // any code including continue, break, return
}

Advantages: familiar to anyone familiar with C-style code, can loop using different strides (e.g. i += 2).

Disadvantages: only for sequential random access containers (vector, array, deque), doesn't work for list, forward_list or the associative containers. Also the loop control is a little verbose (init, check, increment). People need to be aware of the 0-based indexing in C++.

2) iterator-based iteration

for (auto it = v.begin(); it != v.end(); ++it) {
    // if the current index is needed:
    auto i = std::distance(v.begin(), it); 

    // access element as *it

    // any code including continue, break, return
}

Advantages: more generic, works for all containers (even the new unordered associative containers, can also use different strides (e.g. std::advance(it, 2));

Disadvantages: need extra work to get the index of the current element (could be O(N) for list or forward_list). Again, the loop control is a little verbose (init, check, increment).

3) STL for_each algorithm + lambda

std::for_each(v.begin(), v.end(), [](T const& elem) {
     // if the current index is needed:
     auto i = &elem - &v[0];

     // cannot continue, break or return out of the loop
});

Advantages: same as 2) plus small reduction in loop control (no check and increment), this can greatly reduce your bug rate (wrong init, check or increment, off-by-one errors).

Disadvantages: same as explicit iterator-loop plus restricted possibilities for flow control in the loop (cannot use continue, break or return) and no option for different strides (unless you use an iterator adapter that overloads operator++).

4) range-for loop

for (auto& elem: v) {
     // if the current index is needed:
     auto i = &elem - &v[0];

    // any code including continue, break, return
}

Advantages: very compact loop control, direct access to the current element.

Disadvantages: extra statement to get the index. Cannot use different strides.

What to use?

For your particular example of iterating over std::vector: if you really need the index (e.g. access the previous or next element, printing/logging the index inside the loop etc.) or you need a stride different than 1, then I would go for the explicitly indexed-loop, otherwise I'd go for the range-for loop.

For generic algorithms on generic containers I'd go for the explicit iterator loop unless the code contained no flow control inside the loop and needed stride 1, in which case I'd go for the STL for_each + a lambda.

The problem is that the command gets run under sudo, but the redirection gets run under your user. This is done by the shell and there is very little you can do about it.

sudo command > /some/file.log
`-----v-----'`-------v-------'
   command       redirection

The usual ways of bypassing this are:

• Wrap the commands in a script which you call under sudo.

  If the commands and/or log file changes, you can make the script take these as arguments. For example:

  sudo log_script command /log/file.txt
  

• Call a shell and pass the command line as a parameter with -c

  This is especially useful for one off compound commands. For example:

  sudo bash -c "{ command1 arg; command2 arg; } > /log/file.txt"
  

First of all jar creates a jar, and does not run it. Try java -jar instead.

Second, why do you pass the class twice, as FQCN (com.mycomp.myproj.dir2.MainClass2) and as file (com/mycomp/myproj/dir2/MainClass2.class)?

Edit:

It seems as if java -jar requires a main class to be specified. You could try java -cp your.jar com.mycomp.myproj.dir2.MainClass2 ... instead. -cp sets the jar on the classpath and enables java to look up the main class there.

Debian / Ubuntu

The problem is you likely only have the gcc for your current architecture and that's 64bit. You need the 32bit support files. For that, you need to install them

sudo apt install gcc-multilib

I was getting a same error. I found out the solution that I had created the primary key in the main table as BIGINT UNSIGNED and was declaring it as a foreign key in the second table as only BIGINT.

When I declared my foreign key as BIGINT UNSIGED in second table, everything worked fine, even didn't need any indexes to be created.

So it was a datatype mismatch between the primary key and the foreign key :)

Example for .csproj file

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="1.1.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.2" />
    <PackageReference Include="MySql.Data.EntityFrameworkCore" Version="7.0.7-m61" />
  </ItemGroup>

Just get package name and version number from NuGet and add to .csproj then save. You will be prompted to run restore that will import new packages.

Python3 + Using boto3 API approach.

By using S3.Client.download_fileobj API and Python file-like object, S3 Object content can be retrieved to memory.

Since the retrieved content is bytes, in order to convert to str, it need to be decoded.

import io
import boto3

client = boto3.client('s3')
bytes_buffer = io.BytesIO()
client.download_fileobj(Bucket=bucket_name, Key=object_key, Fileobj=bytes_buffer)
byte_value = bytes_buffer.getvalue()
str_value = byte_value.decode() #python3, default decoding is utf-8

If you're using a functional component, you can define defaults in the destructuring assignment, like so:

export default ({ children, id="menu", side="left", image={menu} }) => {
  ...
};

It seems like what you want is http://msdn.microsoft.com/en-us/library/ms186323.aspx.

In your example it would be (starts with):

set @isExpress = (CharIndex('Express Edition', @edition) = 1)

Or contains

set @isExpress = (CharIndex('Express Edition', @edition) >= 1)

In the windows environment use "anaconda prompt" instead of "command prompt".

atoi can do that for you

Example:

char string[] = "1234";
int sum = atoi( string );
printf("Sum = %d\n", sum ); // Outputs: Sum = 1234

first, give the div an id. Then, call function appendClass:

<script language="javascript">
  function appendClass(elementId, classToAppend){
    var oldClass = document.getElementById(elementId).getAttribute("class");
    if (oldClass.indexOf(classToAdd) == -1)
    {
      document.getElementById(elementId).setAttribute("class", classToAppend);
    }
}
</script>

According to http://developer.android.com/tools/debugging/debugging-log.html:

Here's an example of a filter expression that suppresses all log messages except those with the tag "ActivityManager", at priority "Info" or above, and all log messages with tag "MyApp", with priority "Debug" or above:

adb logcat ActivityManager:I MyApp:D *:S

The final element in the above expression, *:S, sets the priority level for all tags to "silent", thus ensuring only log messages with "View" and "MyApp" are displayed.

• V — Verbose (lowest priority)
• D — Debug
• I — Info
• W — Warning
• E — Error
• F — Fatal
• S — Silent (highest priority, on which nothing is ever printed)

I had the same problem too, but I found a solution.

root.mainloop()

from tkinter import *
    
# must add
root = Tk()
root.title("Calculator")
root.iconbitmap(r"image/icon.ico")
    
root.mainloop()

In the example, what python needed is an icon file, so when you dowload an icon as .png it won't work cause it needs an .ico file. So you need to find converters to convert your icon from png to ico.

Here's the correct code. If you're using zybooks this will answer all the problems.

for (int i = 0; i<passCode.length(); i++)
{
    char letter = passCode.charAt(i);
    if (letter == ' ' )
    {
        System.out.println("Space at " + i);
    }
}

You may want to look at Tibbo VSPDL for creating a linux virtual serial port using a Kernel driver -- it seems pretty new, and is available for download right now (beta version). Not sure about the license at this point, or whether they want to make it available commercially only in the future.

There are other commercial alternatives, such as http://www.ttyredirector.com/.

In Open Source, Remserial (GPL) may also do what you want, using Unix PTY's. It transmits the serial data in "raw form" to a network socket; STTY-like setup of terminal parameters must be done when creating the port, changing them later like described in RFC 2217 does not seem to be supported. You should be able to run two remserial instances to create a virtual nullmodem like com0com, except that you'll need to set up port speed etc in advance.

Socat (also GPL) is like an extended variant of Remserial with many many more options, including a "PTY" method for redirecting the PTY to something else, which can be another instance of Socat. For Unit tets, socat is likely nicer than remserial because you can directly cat files into the PTY. See the PTY example on the manpage. A patch exists under "contrib" to provide RFC2217 support for negotiating serial line settings.

I got the same error with vlc component when i changed the framework from 4.5 to 4. but it worked for me when I changed the platform from Any CPU to x86.

The mouseenter event differs from mouseover in the way it handles event bubbling. The mouseenter event, only triggers its handler when the mouse enters the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseenter/

The mouseleave event differs from mouseout in the way it handles event bubbling. The mouseleave event, only triggers its handler when the mouse leaves the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseleave/

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

As mentioned before, the use of x(end+1) = newElem has the advantage that it allows you to concatenate your vector with a scalar, regardless of whether your vector is transposed or not. Therefore it is more robust for adding scalars.

However, what should not be forgotten is that x = [x newElem] will also work when you try to add multiple elements at once. Furthermore, this generalizes a bit more naturally to the case where you want to concatenate matrices. M = [M M1 M2 M3]

All in all, if you want a solution that allows you to concatenate your existing vector x with newElem that may or may not be a scalar, this should do the trick:

 x(end+(1:numel(newElem)))=newElem

Try using unbindService() in OnUserLeaveHint(). It prevents the the ServiceConnection leaked scenario and other exceptions.
I used it in my code and works fine.

Try this code:-

var input string
func main() {
      fmt.Print("Enter Your Name=")
      fmt.Scanf("%s",&input)
      fmt.Println("Hello "+input)
      }

sumr is implemented in terms of foldRight:

 final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append) 

foldRight is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

You can try

<column_name> is null

in the where clause.

suppressWarnings() has already been mentioned. An alternative is to manually convert the problematic characters to NA first. For your particular problem, taRifx::destring does just that. This way if you get some other, unexpected warning out of your function, it won't be suppressed.

> library(taRifx)
> x <- as.numeric(c("1", "2", "X"))
Warning message:
NAs introduced by coercion 
> y <- destring(c("1", "2", "X"))
> y
[1]  1  2 NA
> x
[1]  1  2 NA

As explained @Yaroslav Stavnichiy if a service is marked as transactional spring tries to handle transaction itself. If any exception occurs then a rollback operation performed. If in your scenario ServiceUser.method() is not performing any transactional operation you can use @Transactional.TxType annotation. 'NEVER' option is used to manage that method outside transactional context.

Transactional.TxType reference doc is here.

In addition to the solution with 'aaaaaaaa' LIKE '%' || tag_name || '%' there are position (reversed order of args) and strpos.

SELECT id FROM TAG_TABLE WHERE strpos('aaaaaaaa', tag_name) > 0

Besides what is more efficient (LIKE looks less efficient, but an index might change things), there is a very minor issue with LIKE: tag_name of course should not contain % and especially _ (single char wildcard), to give no false positives.

This is probably the best solution you'll get. Simple and Easy. I learned it on udemy. Suppose you have two images having image id's id1 and id2 respectively and currently the image view is set as id1 and you want to change it to the other image everytime someone clicks in. So this is the basic code in MainActivity.java File

int clickNum=0;
public void click(View view){
clickNum++;
ImageView a=(ImageView)findViewById(R.id.id1);
ImageView b=(ImageView)findViewById(R.id.id2);
if(clickNum%2==1){
  a.animate().alpha(0f).setDuration(2000); //alpha controls the transpiracy
}
else if(clickNum%2==0){
  b.animate().alpha(0f).setDuration(2000); //alpha controls the transpiracy
}

}

I hope this will surely help

Using the builtin Date.parse function which accepts input in ISO8601 format and directly returns the desired integer return value:

var dates_as_int = dates.map(Date.parse);

dragonfly's answer worked for me (python 3.4.3).

import sys
del sys.modules['module_name']

Here is a lower level solution :

exec(open("MyClass.py").read(), globals())

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

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

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

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

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

Either use casting as others have already said, or multiply one of the int variables by 1.0:

double firstSolution = ((1.0* b1 * a22 - b2 * a12) / (a11 * a22 - a12 * a21));

Find below some characteristics of clustered and non-clustered indexes:

Clustered Indexes

1. Clustered indexes are indexes that uniquely identify the rows in an SQL table.
2. Every table can have exactly one clustered index.
3. You can create a clustered index that covers more than one column. For example: create Index index_name(col1, col2, col.....).
4. By default, a column with a primary key already has a clustered index.

Non-clustered Indexes

1. Non-clustered indexes are like simple indexes. They are just used for fast retrieval of data. Not sure to have unique data.

FIX FOR MYSQL IN DOCKER

I'm using @fefe's excellent answer here to show how to fix this problem within some minutes when using docker (via docker-compose). It's quite easy as you don't have to touch MySQL's configuration files, but it requires you to export and import your entire data:

The default situation of your MySQL setup probably looks like this. Your data is saved inside the data-mysql volume.

mysql:
  image: mysql:5.7.25
  container_name: mysql
  restart: always
  volumes:
    - data-mysql:/var/lib/mysql
  environment:
    - "MYSQL_DATABASE=XXX"
    - "MYSQL_USER=XXX"
    - "MYSQL_PASSWORD=XXX"
    - "MYSQL_ROOT_PASSWORD=XXX"
  expose:
    - 3306

1. Make a backup of your entire data/database via SQL export, so you have a .sql.gz or something. I'm using Adminer for this.

2. To fix (and as explained in @fefe's answer) we have to setup the MySQL instance from zero, meaning we have to delete the mysql docker container and the mysql volume docker container. Do a docker container ls and a docker volume ls to see all your containers and volumes, and pick the two names that are your mysql instance and your mysql volume, for me it's mysql (container) and docker_data-mysql (volume).

3. Stop your running instances via docker-compose down (or however you usually stop your docker stuff).

4. To delete them, I do docker container rm mysql and docker volume rm docker_data-mysql (note that there is an underscore AND a dash in the name).

5. Add these settings to your mysql block in your docker setup:

mysql:
  image: mysql:5.7.25
  command: ['--innodb_page_size=64k', '--innodb_log_buffer_size=32M', '--innodb_buffer_pool_size=512M']
  container_name: mysql
  # ...

6. Restart your instances, the mysql and mysql volume should be build automatically, now with the new settings.

7. Import your database dump file, maybe with:

gzip -dc < database.sql.gz | docker exec -i mysql mysql -uroot -pYOURPASSWORD

Voila! Worked very fine for me!

Use <f:convertDateTime>. You can nest this in any input and output component. Pattern rules are same as java.text.SimpleDateFormat.

<h:outputText value="#{someBean.dateField}" >
    <f:convertDateTime pattern="dd.MM.yyyy HH:mm" />
</h:outputText>

First you need to publish the file by:

1. BUILD -> PUBLISH or by right clicking project on Solution Explorer -> properties -> publish or select project in Solution Explorer and press Alt + Enter NOTE: if you are using Visual Studio 2013 then in properties you have to go to BUILD and then you have to disable define DEBUG constant and define TRACE constant and you are ready to go.

2. Save your file to a particular folder. Find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj). In Visual Studio they are in the Application Files folder and inside that you just need the .exe and dll files. (You have to delete ClickOnce and other files and then make this folder a zip file and distribute it.)

NOTE: The ClickOnce application does install the project to system, but it has one advantage. You DO NOT require administrative privileges here to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

If you only want to print this div, you must use the instruction:

@media print{
    *{display:none;}
    #mydiv{display:block;}
}

This works in Bootstrap 3 and improves dubbe and flynfish 's 2 top answers by integrating GarciaWebDev 's answer as well (which allows for url parameters after the hash and is straight from Bootstrap authors on the github issue tracker):

var prefix = "tab_";

if (hash) {
    hash = hash.replace(prefix,'');
    var hashPieces = hash.split('?');
    activeTab = $('.nav-tabs a[href=' + hashPieces[0] + ']');
    activeTab && activeTab.tab('show');
} 

// Change hash for page-reload
$('.nav-tabs a').on('shown', function (e) {
    window.location.hash = e.target.hash.replace("#", "#" + prefix);
});

pmListener.js is a post message url listener

//pmListener.js

//Listen to messages from Content Script and Execute Them
window.addEventListener("message", function (msg) {
  console.log("im in REAL DOM");
  if (msg.data.cmnd) {
    eval(msg.data.cmnd);
  }
});

console.log("injected To Real Dom");

This way , I can have 2 way communication between CS to Real Dom. Its very usefull for example if you need to listen webscoket events , or to any in memory variables or events.

You can delete multiple branches on windows using Git GUI:

1. Go to your Project folder
2. Open Git Gui:
3. Click on 'Branch':
4. Now choose 'Delete':
5. If you want to delete all branches besides the fact they are merged or not, then check 'Always (Do not perform merge checks)'

I think you can normalize the row elements sum to 1 by this: new_matrix = a / a.sum(axis=1, keepdims=1). And the column normalization can be done with new_matrix = a / a.sum(axis=0, keepdims=1). Hope this can hep.

The equivalence would be

for i in (0...array.size)
end

or

(0...array.size).each do |i|
end

or

i = 0
while i < array.size do
   array[i]
   i = i + 1 # where you may freely set i to any value
end

This is holmberd answer with a "table header" implementation

function createTable(tableData) {
  var table = document.createElement('table');
  var header = document.createElement("tr");
  // get first row to be header
  var headers = tableData[0];

  // create table header
  headers.forEach(function(rowHeader){
    var th = document.createElement("th");
    th.appendChild(document.createTextNode(rowHeader));
    header.appendChild(th);
  });      
  console.log(headers);

  // insert table header 
  table.append(header);
  var row = {};
  var cell = {};

  // remove first how - header
  tableData.shift();
  tableData.forEach(function(rowData, index) {
    row = table.insertRow();
    console.log("indice: " + index);
    rowData.forEach(function(cellData) {
      cell = row.insertCell();
            cell.textContent = cellData;
    });
  });
  document.body.appendChild(table);
}

createTable([["row 1, cell 1", "row 1, cell 2"], ["row 2, cell 1", "row 2, cell 2"], ["row 3, cell 1", "row 3, cell 2"]]);

I have had to do this in cases where documents such as word docs and pdfs were being streamed to the iframe and found a solution that works pretty well. The key is handling the onreadystatechanged event on the iframe.

Lets say the name of your frame is "myIframe". First somewhere in your code startup (I do it inline any where after the iframe) add something like this to register the event handler:

document.getElementById('myIframe').onreadystatechange = MyIframeReadyStateChanged;

I was not able to use an onreadystatechage attribute on the iframe, I can't remember why, but the app had to work in IE 7 and Safari 3, so that may of been a factor.

Here is an example of a how to get the complete state:

function MyIframeReadyStateChanged()
{
    if(document.getElementById('myIframe').readyState == 'complete')
    {
        // Do your complete stuff here.
    }
}

if you have options

return this.http.post(`${this.endpoint}/account/login`,payload, { ...options, responseType: 'text' })

There was no information in my Console so that sent me searching for additional solutions and found these - unique to the solutions presented here. I encountered this with Eclipse Oxygen trying to run an old Ant build on a project.

Cause 1 I had configured Eclipse to use an external Ant install which was version 1.10.2 which apparently had classes in it that were compiled with JDK 9. In Eclipse I got the JNI error described above (running the Ant build at the command line gave me the reknowned 'unsupported major.minor version' error - the Java I was using on the system was JDK 8).

The solution was to rollback to the embedded Eclipse version of Ant being 1.10.1. I verified this as the correct solution by downloading Ant 1.10.1 separately and reconfiguring Eclipse to use the new 1.10.1 externally and it still worked.

Cause 2 This can also happen when you have the Ant Runtime settings configured incorrectly in Eclipse's Preferences. Depending on the version of Ant you're running you will need to add the tools.jar from the appropriate JDK to the classpath used for the Ant Runtime (Home Entries). More specifically, without a proper configuration, Eclipse will complain when launching an Ant target that the JRE version is less than a particular required version.

Essentially, 'proper configuration' means aligning each of the configuration items in Eclipse for running Ant so that they all work together. This involves the Ant Runtime Home entry (must point to an Ant version that is compatible with your chosen JDK -- you can't run Ant with JDK 8 when it was compiled against JDK 9); specifying the tools.jar that belongs to the JDK you want to run Ant with in the Ant Runtime settings; and lastly setting the JRE environment of your build script to the JDK you want to run Ant with in the External Tools Configuration. All 3 of these settings need to agree to avoid the error described above. You'll also need to consider the attributes used in your javac tag to ensure the JDK you're using is capable of executing as you've directed (i.e. JDK 7 can't compile code using source and target version 8).

Moreover If you're really just trying to run an Ant build script to compile code to an older JDK (e.g. less than 8 for Oxygen), this article helped gain access to run Ant against an older JDK. There are Ant plugin replacements for a handful of versions of Eclipse, the instructions are brief and getting the correct plugin version for your particular Eclipse is important.

Or more simply you can use this very good solution to do your legacy compile which doesn't require replacing your Eclipse plugin but instead changing the javac tag in your build script (while using the latest JDK).

Yet, it is possible to fake it using a dedicated table, named for your fake-sp, with an AFTER INSERT trigger. The dedicated table rows contain the parameters for your fake sp, and if it needs to return results you can have a second (poss. temp) table (with name related to the fake-sp) to contain those results. It would require two queries: first to INSERT data into the fake-sp-trigger-table, and the second to SELECT from the fake-sp-results-table, which could be empty, or have a message-field if something went wrong.

This might be a late answer but this is the best around: https://github.com/eKoopmans/html2pdf

Pure javascript implementation. Allows you to specify just a single element by ID and convert it.

Since you are on 10g, you could potentially use the ORA_ROWSCN pseudocolumn. That gives you an upper bound of the last SCN (system change number) that caused a change in the row. Since this is an increasing sequence, you could store off the maximum ORA_ROWSCN that you've seen and then look only for data with an SCN greater than that.

By default, ORA_ROWSCN is actually maintained at the block level, so a change to any row in a block will change the ORA_ROWSCN for all rows in the block. This is probably quite sufficient if the intention is to minimize the number of rows you process multiple times with no changes if we're talking about "normal" data access patterns. You can rebuild the table with ROWDEPENDENCIES which will cause the ORA_ROWSCN to be tracked at the row level, which gives you more granular information but requires a one-time effort to rebuild the table.

Another option would be to configure something like Change Data Capture (CDC) and to make your OCI application a subscriber to changes to the table, but that also requires a one-time effort to configure CDC.

You can use this code to get current URL:

echo url()->current();

echo url()->full();

I get this from Laravel documents.

Thanks Chad! To show all the errors associated with the key, here's what I came up with. For some reason the base Html.ValidationMessage helper only shows the first error associated with the key.

    <%= Html.ShowAllErrors(mykey) %>

HtmlHelper:

    public static String ShowAllErrors(this HtmlHelper helper, String key) {
        StringBuilder sb = new StringBuilder();
        if (helper.ViewData.ModelState[key] != null) {
            foreach (var e in helper.ViewData.ModelState[key].Errors) {
                TagBuilder div = new TagBuilder("div");
                div.MergeAttribute("class", "field-validation-error");
                div.SetInnerText(e.ErrorMessage);
                sb.Append(div.ToString());
            }
        }
        return sb.ToString();
    }

1. Install android sdk manager
2. check if building tools installed. install api 23.
3. from the Android SDK Manager download the 'Android Support Repository'
4. remove cordova-plugin-android-support-v4
5. build

Realize this is an old thread but here are a couple other ways (works with EAP 6.4):

1. Use JBoss CLI (/opt/jboss/bin)

# jboss-cli.sh -c --controller=127.0.0.1:9999 'version' JBoss Admin Command-line Interface JBOSS_HOME: /opt/AAS/latest/jboss JBoss AS release: 7.5.14.Final-redhat-2 "Janus" JBoss AS product: EAP 6.4.14.GA

2. Inspect the identity.conf file

# more /opt/jboss/.installation/identity.conf patches= cumulative-patch-id=jboss-eap-6.4.14.CP installed-patches=jboss-eap-6.4.1.CP,jboss-eap-6.4.2.CP,jboss-eap-6.4.3.CP,jboss-eap-6.4.4.CP,jboss-eap-6.4.5.CP,jboss-eap-6.4.6.CP,jboss-eap-6.4.7.CP,jboss-eap-6.4.8.CP,jboss-eap-6.4.9.CP, jboss-eap-6.4.10.CP,jboss-eap-6.4.11.CP,jboss-eap-6.4.12.CP,jboss-eap-6.4.13.CP,jboss-eap-6.4.14.CP

Try this:

> HISTTIMEFORMAT="%d/%m/%y %T "

> history

You can adjust the format to your liking, of course.

Find the location of the .bash_profile file and enter the following into the file:

setterm -blength 0

Which will set the amount of time the beep happens to 0 and thus no beep.

Here are a few popular examples:

<div>{{myDate | date:'M/d/yyyy'}}</div> 7/4/2014

<div>{{myDate | date:'yyyy-MM-dd'}}</div> 2014-07-04

<div>{{myDate | date:'M/d/yyyy HH:mm:ss'}}</div> 7/4/2014 12:01:59

A couple of quick notes:

• It's "length" not "lenght"
• Table aliases in your query would probably make it a lot more readable

Now onto the problem...

You need to explicitly convert your parameters to VARCHAR before trying to concatenate them. When SQL Server sees @my_int + 'X' it thinks you're trying to add the number "X" to @my_int and it can't do that. Instead try:

SET @ActualWeightDIMS =
     CAST(@Actual_Dims_Lenght AS VARCHAR(16)) + 'x' +
     CAST(@Actual_Dims_Width  AS VARCHAR(16)) + 'x' +
     CAST(@Actual_Dims_Height  AS VARCHAR(16))

You can use the following query for MYSQL:

SHOW `columns` FROM `your-table`;

Below is the example code which shows How to implement above syntax in php to list the names of columns:

$sql = "SHOW COLUMNS FROM your-table";
$result = mysqli_query($conn,$sql);
while($row = mysqli_fetch_array($result)){
    echo $row['Field']."<br>";
}

For Details about output of SHOW COLUMNS FROM TABLE visit: MySQL Refrence.

You should check for (args == null || args.length == 0). Although the null check isn't really needed, it is a good practice.

If you want to return some value then wrap your statement in function

function my_function(){ 

 return my_thing; 
}

Problem is with the statement on the 1st line if you are trying to use PHP

var ask = confirm ('".$message."'); 

IF you are trying to use PHP you should use

 var ask = confirm (<?php echo "'".$message."'" ?>); //now message with be the javascript string!!

I am using Ubuntu and my sessions are stored in /var/lib/php5.

To get the currently logged in user:

System.getProperty("user.name"); //platform independent 

and the hostname of the machine:

java.net.InetAddress localMachine = java.net.InetAddress.getLocalHost();
System.out.println("Hostname of local machine: " + localMachine.getHostName());

cat file.txt | wc -l

According to the man page (for the BSD version, I don't have a GNU version to check):

If no files are specified, the standard input is used and no file name is displayed. The prompt will accept input until receiving EOF, or [^D] in most environments.

delete is used for one single pointer and delete[] is used for deleting an array through a pointer. This might help you to understand better.

Use the following regex

^(\+91[\-\s]?)?[0]?(91)?[789]\d{9}$

This will support the following formats:

1. 8880344456
2. +918880344456
3. +91 8880344456
4. +91-8880344456
5. 08880344456
6. 918880344456

I have a Samsung Galaxy and I had the same issue as you. Here's how to fix it:

In device manager on your Windows PC, even though it might say the USB drivers are installed correctly, there may exist corruption.

I went into device manager and uninstalled SAMSUNG Android USB Composite Device and made sure to check the box 'delete driver software'. Now the device will have an exclamation mark etc. I right clicked and installed the driver again (refresh copy). This finally made adb acknowledge my phone as an emulator.

As others noted, for Nexus 4, you can also try this fix.

This is my way, using location from props. I don't know but history.isActive got undefined for me

export default class Navbar extends React.Component {
render(){
const { location } = this.props;

const homeClass = location.pathname === "/" ? "active" : "";
const aboutClass = location.pathname.match(/^\/about/) ? "active" : "";
const contactClass = location.pathname.match(/^\/contact/) ? "active" : "";


return (
<div>
      <ul className="nav navbar-nav navbar-right">
        <li className={homeClass}><Link to="/">Home</Link></li>
        <li className={aboutClass}><Link to="about" activeClassName="active">About</Link></li>
        <li className={contactClass}><Link to="contact" activeClassName="active">Contact</Link></li>
      </ul>

</div>
    );}}

The difference between the two is best brought in what seems a necessary and sufficient definition of the dependencyManagement element available in Maven website docs:

dependencyManagement

"Default dependency information for projects that inherit from this one. The dependencies in this section are not immediately resolved. Instead, when a POM derived from this one declares a dependency described by a matching groupId and artifactId, the version and other values from this section are used for that dependency if they were not already specified." [ https://maven.apache.org/ref/3.6.1/maven-model/maven.html ]

It should be read along with some more information available on a different page:

“..the minimal set of information for matching a dependency reference against a dependencyManagement section is actually {groupId, artifactId, type, classifier}. In many cases, these dependencies will refer to jar artifacts with no classifier. This allows us to shorthand the identity set to {groupId, artifactId}, since the default for the type field is jar, and the default classifier is null.” [https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html ]

Thus, all the sub-elements (scope, exclusions etc.,) of a dependency element--other than groupId, artifactId, type, classifier, not just version--are available for lockdown/default at the point (and thus inherited from there onward) you specify the dependency within a dependencyElement. If you’d specified a dependency with the type and classifier sub-elements (see the first-cited webpage to check all sub-elements) as not jar and not null respectively, you’d need {groupId, artifactId, classifier, type} to reference (resolve) that dependency at any point in an inheritance originating from the dependencyManagement element. Else, {groupId, artifactId} would suffice if you do not intend to override the defaults for classifier and type (jar and null respectively). So default is a good keyword in that definition; any sub-element(s) (other than groupId, artifactId, classifier and type, of course) explicitly assigned value(s) at the point you reference a dependency override the defaults in the dependencyManagement element.

So, any dependency element outside of dependencyManagement, whether as a reference to some dependencyManagement element or as a standalone is immediately resolved (i.e. installed to the local repository and available for classpaths).

ALTER TABLE `subscriber_surname` ADD  IF NOT EXISTS  `#__comm_subscribers`.`subscriber_surname`;

ALTER TABLE `#__comm_subscribers` MODIFY `subscriber_surname` varchar(64) NOT NULL default '';

In C# you can use the following to replace the single quote with a double quote:

 string sample = "St. Mary's";
 string escapedSample = sample.Replace("'", "''");

And the output will be:

"St. Mary''s"

And, if you are working with Sqlite directly; you can work with object instead of string and catch special things like DBNull:

private static string MySqlEscape(Object usString)
{
    if (usString is DBNull)
    {
        return "";
    }
    string sample = Convert.ToString(usString);
    return sample.Replace("'", "''");
}

If you want to return from an outer function with an error without exiting you can use this trick:

do-something-complex() {
  # Using `return` here would only return from `fail`, not from `do-something-complex`.
  # Using `exit` would close the entire shell.
  # So we (ab)use a different feature. :)
  fail() { : "${__fail_fast:?$1}"; }

  nested-func() {
      try-this || fail "This didn't work"
      try-that || fail "That didn't work"
  }
  nested-func
}

Trying it out:

$ do-something-complex
try-this: command not found
bash: __fail_fast: This didn't work

This has the added benefit/drawback that you can optionally turn off this feature: __fail_fast=x do-something-complex.

Note that this causes the outermost function to return 1.

Django querysets are lazy. That means a query will hit the database only when you specifically ask for the result.

So until you print or actually use the result of a query you can filter further with no database access.

As you can see below your code only executes one sql query to fetch only the last 10 items.

In [19]: import logging                                 
In [20]: l = logging.getLogger('django.db.backends')    
In [21]: l.setLevel(logging.DEBUG)                      
In [22]: l.addHandler(logging.StreamHandler())      
In [23]: User.objects.all().order_by('-id')[:10]          
(0.000) SELECT "auth_user"."id", "auth_user"."username", "auth_user"."first_name", "auth_user"."last_name", "auth_user"."email", "auth_user"."password", "auth_user"."is_staff", "auth_user"."is_active", "auth_user"."is_superuser", "auth_user"."last_login", "auth_user"."date_joined" FROM "auth_user" ORDER BY "auth_user"."id" DESC LIMIT 10; args=()
Out[23]: [<User: hamdi>]

Use keyword arguments with defaults. E.g.

def add_bullet(sprite, start=default, direction=default, script=default, speed=default):

In the case of a straight bullet versus a curved bullet, I'd add two functions: add_bullet_straight and add_bullet_curved.

height and depth of a tree is equal...

but height and depth of a node is not equal because...

the height is calculated by traversing from the given node to the deepest possible leaf.

depth is calculated from traversal from root to the given node.....

Use a custom UINavigationController subclass, which implements the shouldPop method.

In Swift:

class NavigationController: UINavigationController, UINavigationBarDelegate
{
    var shouldPopHandler: (() -> Bool)?

    func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool
    {
        if let shouldPopHandler = self.shouldPopHandler, !shouldPopHandler()
        {
            return false
        }
        self.popViewController(animated: true) // Needed!
        return true
    }
}

When set, your shouldPopHandler() will be called to decide whether the controller will be pop or not. When not set it will just get popped as usual.

It is a good idea to disable UINavigationControllers interactivePopGestureRecognizer as the gesture won't call your handler otherwise.

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

Try with array_merge_recursive

$A = array('a' => 1, 'b' => 2, 'c' => 3);
$B = array('c' => 4, 'd'=> 5);
$c = array_merge_recursive($A,$B);

echo "<pre>";
print_r($c);
echo "</pre>";

will return

Array
(
    [a] => 1
    [b] => 2
    [c] => Array
        (
            [0] => 3
            [1] => 4
        )

    [d] => 5
)

Just do select date(timestamp_column) and you would get the only the date part. Sometimes doing select timestamp_column::date may return date 00:00:00 where it doesn't remove the 00:00:00 part. But I have seen date(timestamp_column) to work perfectly in all the cases. Hope this helps.

In addition to other answers which helped me, you can also add to surrounding div. In my case this was for sign on with user Name/Password fields.

<div (keyup.enter)="login()" class="container-fluid">

It is an old question, but I just ran into it. Type.GetMethod(string name) will throw an AmbiguousMatchException if there is more than one method with that name, so we better handle that case

public static bool HasMethod(this object objectToCheck, string methodName)
{
    try
    {
        var type = objectToCheck.GetType();
        return type.GetMethod(methodName) != null;
    }
    catch(AmbiguousMatchException)
    {
        // ambiguous means there is more than one result,
        // which means: a method with that name does exist
        return true;
    }
} 

I can't say how much this might help you, but just found a solution to something similar problem which I faced. In the Pivot-

1. Right click and choose Pivot table options
2. Choose the display option
3. uncheck the first 'Show expand/Collapse buttons'
4. check the 'Classic PivotTable Layout(enables dragging of fields in the grid)
5. click ok.

This would refine the data. Then, I had just copy and pasted this data in a new tab wherein I had applied the filters to my Total column with values greater than certain percentage.

This did work in my case and hope it helps you too.

var ret = "data-123".replace('data-','');_x000D_
console.log(ret);   //prints: 123

Docs.

For all occurrences to be discarded use:

var ret = "data-123".replace(/data-/g,'');

PS: The replace function returns a new string and leaves the original string unchanged, so use the function return value after the replace() call.

Removing from an array itself is not simple, as you then have to deal with resizing. This is one of the great advantages of using something like a List<int> instead. It provides Remove/RemoveAt in 2.0, and lots of LINQ extensions for 3.0.

If you can, refactor to use a List<> or similar.

A very basic example of Implicits in scala.

Implicit parameters:

val value = 10
implicit val multiplier = 3
def multiply(implicit by: Int) = value * by
val result = multiply // implicit parameter wiil be passed here
println(result) // It will print 30 as a result

Note: Here multiplier will be implicitly passed into the function multiply. Missing parameters to the function call are looked up by type in the current scope meaning that code will not compile if there is no implicit variable of type Int in the scope.

Implicit conversions:

implicit def convert(a: Double): Int = a.toInt
val res = multiply(2.0) // Type conversions with implicit functions
println(res)  // It will print 20 as a result

Note: When we call multiply function passing a double value, the compiler will try to find the conversion implicit function in the current scope, which converts Int to Double (As function multiply accept Int parameter). If there is no implicit convert function then the compiler will not compile the code.

You can find out the Android version looking at Build.VERSION.

The documentation recommends you check Build.VERSION.SDK_INT against the values in Build.VERSION_CODES.

This is fine as long as you realise that Build.VERSION.SDK_INT was only introduced in API Level 4, which is to say Android 1.6 (Donut). So this won't affect you, but if you did want your app to run on Android 1.5 or earlier then you would have to use the deprecated Build.VERSION.SDK instead.

Just set Null to ignore parameters that you don't want to use and then set the parameter needed according to the position.

 function myFunc($p1,$p2,$p3=Null,$p4=Null,$p5=Null,$p6=Null,$p7=Null,$p8=Null){
    for ($i=1; $i<9; $i++){
        $varName = "p$i";
        if (isset($$varName)){
            echo $varName." = ".$$varName."<br>\n";
        }
    }
}   

myFunc( "1", "2", Null, Null, Null, Null, Null, "eight" );

Tried other variants, this can be proper

    Logger logger = Logger.getLogger(MyClass.class.getName());        
    Level level = Level.ALL;
    for(Handler h : java.util.logging.Logger.getLogger("").getHandlers())    
        h.setLevel(level);
    logger.setLevel(level);
// this must be shown
    logger.fine("fine");
    logger.info("info");

std::copy (b.begin(), b.end(), std::back_inserter(a));

This can be used in case the items in vector a have no assignment operator (e.g. const member).

In all other cases this solution is ineffiecent compared to the above insert solution.

If you're looking to capture everything up to "abc":

/^(.*?)abc/

Explanation:

( ) capture the expression inside the parentheses for access using $1, $2, etc.

^ match start of line

.* match anything, ? non-greedily (match the minimum number of characters required) - [1]

[1] The reason why this is needed is that otherwise, in the following string:

whatever whatever something abc something abc

by default, regexes are greedy, meaning it will match as much as possible. Therefore /^.*abc/ would match "whatever whatever something abc something ". Adding the non-greedy quantifier ? makes the regex only match "whatever whatever something ".

Swamibebop's solution works, but by taking advantage of table.* syntax, we can avoid repeating the column names of the inner select and get a simpler/shorter result:

SELECT @r := @r+1 , 
       z.* 
FROM(/* your original select statement goes in here */)z, 
(SELECT @r:=0)y;

So that will give you:

SELECT @r := @r+1 , 
       z.* 
FROM(
     SELECT itemID, 
     count(*) AS ordercount
     FROM orders
     GROUP BY itemID
     ORDER BY ordercount DESC
    )z,
    (SELECT @r:=0)y;

Here try this out.

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

The problem is just in naming folder, if your folder to save your project contains special characters then remove them. If the error persists try to save the folder with no space.

Found an easy way which works with all browsers I have (Chrome 49, Edge 25, Firefox 44, IE11, Safari 5 [Win], Safari 8 (MacOS)) :

// Note : .html('') doesn't works for svg in some browsers_x000D_
$('#svgObject').empty();_x000D_
// add some objects_x000D_
$('#svgObject').append('<polygon class="svgStyle" points="10,10 50,10 50,50 10,50 10,10" />');_x000D_
$('#svgObject').append('<circle class="svgStyle" cx="100" cy="30" r="25"/>');_x000D_
_x000D_
// Magic happens here: refresh DOM (you must refresh svg's parent for Edge/IE and Safari)_x000D_

The Lazy<T> version:

public sealed class Singleton
{
    private static readonly Lazy<Singleton> lazy
        = new Lazy<Singleton>(() => new Singleton());

    public static Singleton Instance
        => lazy.Value;

    private Singleton() { }
}

Requires .NET 4 and C# 6.0 (VS2015) or newer.

This feature is in pre-release now and works with Visual Studio 2015.

For example:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    [DataRow(1, 2, 2)]
    [DataRow(2, 3, 5)]
    [DataRow(3, 5, 8)]
    public void AdditionTest(int a, int b, int result)
    {
        Assert.AreEqual(result, a + b);
    }
}

In my case a dependency was missing in the dll that threw this exception. I checked with Dependency Walker, added the missing dll and the problem was resolved.

More specifically, I somehow corrupted my opencv_core340.dll by accidentally adding SVN keywords to it, and thus my dll could no longer use it. However I don't believe that the solution to this problem depends on whether the dll is corrupted or missing. I'm just adding this for the sake of giving complete information.

Is this possible in angular 2?

Yes, it is possible.

If both of the conditions are true, will they enable the button?

No, if they are true, then the button will be disabled. disabled="true".

I try the above code but it's not working well

What did you expect? the button will be disabled when valid is false and the angular formGroup, SAForm is not valid.

A recommendation here as well, Please make the button of type button not a submit because this may cause the whole form to submit and you would need to use invalidate and listen to (ngSubmit).

Make it

float b= 3.6f;

A floating-point literal is of type float if it is suffixed with an ASCII letter F or f; otherwise its type is double and it can optionally be suffixed with an ASCII letter D or d

Here's another way to do it: as we all know 1x byte = 8x bits and also, a "regular" integer (int32) contains 32 bits (4 bytes). We can use the >> operator to shift bits right (>> operator does not change value.)

int intValue = 566;

byte[] bytes = new byte[4];

bytes[0] = (byte)(intValue >> 24);
bytes[1] = (byte)(intValue >> 16);
bytes[2] = (byte)(intValue >> 8);
bytes[3] = (byte)intValue;

Console.WriteLine("{0} breaks down to : {1} {2} {3} {4}",
    intValue, bytes[0], bytes[1], bytes[2], bytes[3]);

It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:

var canvas = document.createElement('canvas');
canvas.id     = "CursorLayer";
canvas.width  = 1224;
canvas.height = 768;
canvas.style.zIndex   = 8;
canvas.style.position = "absolute";
canvas.style.border   = "1px solid";
window.onload = function() {
    document.getElementById("CursorLayer");
}

What is an Intent?

An Intent is a specific command in Android that allows you to send a command to the Android OS to do something specific. Think of it as an action that needs to take place. There are many actions that can be done such as sending an email, or attaching a photo to an email, or even launching an application. The logical workflow of creating an intent is usually as follows: a. Create the Intent b. Add Intent options -> Ex. what type of intent we are sending to the OS or any attributes associated with that intent, such as a text string or something being passed along with the intent c. RUN the Intent

Real-Life Example: Let's say I wake up in the morning and I "INTEND" to go to the washroom. I will first have to THINK about going to the washroom, but that DOESN'T really gets me to the washroom. I will then have to tell my brain to get out of bed first, then walk to the washroom, and then release, then go and wash my hands, then go and wipe my hands. Once I know where I'm going I SEND the command to begin and my body takes action.

What is Pending Intents?

Continuing from the real-life example, let's say I want to take a shower but I want to shower AFTER I brush my teeth and eat breakfast. So I know I won't be showering until at least 30-40 minutes. I still have in my head that I need to prepare my clothes, and then walk up the stairs back to the bathroom, then undress and then shower. However, this will not happen until 30-40 minutes have passed. I now have a PENDING intent to shower. It is PENDING for 30-40 minutes.

That is pretty much the difference between a Pending Intent and a Regular Intent. Regular Intents can be created without a Pending Intent, however, in order to create a Pending Intent you need to have a Regular Intent setup first.

So what is the URL that Yii::app()->params['pdfUrl'] gives? You say it should be https, but the log shows it's connecting on port 80... which almost no server is setup to accept https connections on. cURL is smart enough to know https should be on port 443... which would suggest that your URL has something wonky in it like: https://196.41.139.168:80/serve/?r=pdf/generatePdf

That's going to cause the connection to be terminated, when the Apache at the other end cannot do https communication with you on that port.

You realize your first $body definition gets replaced when you set $body to an array two lines later? {Probably just an artifact of you trying to solve the problem} You're also not encoding the client_url and client_id values (the former quite possibly containing characters that need escaping!) Oh and you're appending to $body_str without first initializing it.

From your verbose output we can see cURL is adding a content-length header, but... is it correct? I can see some comments out on the internets of that number being wrong (especially with older versions)... if that number was to small (for example) you'd get a connection-reset before all the data is sent. You can manually insert the header:

curl_setopt ($c, CURLOPT_HTTPHEADER, 
   array("Content-Length: ". strlen($body_str))); 

Oh and there's a handy function http_build_query that'll convert an array of name/value pairs into a URL encoded string for you.

All this rolls up into the final code:

$post=http_build_query(array(
  "client_url"=>Yii::app()->params['pdfClientURL'],
  "client_id"=>Yii::app()->params['pdfClientID'],
  "title"=>$title,
  "content"=>$content));

//Open to URL
$c=curl_init(Yii::app()->params['pdfUrl']);
//Send post
curl_setopt ($c, CURLOPT_POST, true);
//Optional: [try with/without]
curl_setopt ($c, CURLOPT_HTTPHEADER, array("Content-Length: ".strlen($post))); 
curl_setopt ($c, CURLOPT_POSTFIELDS, $post);
curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($c, CURLOPT_CONNECTTIMEOUT , 0);
curl_setopt ($c, CURLOPT_TIMEOUT  , 20);
//Collect result
$pdf = curl_exec ($c);
$curlInfo = curl_getinfo($c);
curl_close($c);

I just created my own version using CSS. As I need to disabled, then when document is ready use jQuery to make active. So that way a user cannot click on a button until after the document is ready. So i can substitute with AJAX instead. The way I came up with, was to add a class to the anchor tag itself and remove the class when document is ready. Could re-purpose this for your needs.

CSS:

a.disabled{
    pointer-events: none;
    cursor: default;
}

HTML:

<a class="btn btn-info disabled">Link Text</a>

JS:

$(function(){
    $('a.disabled').on('click',function(event){
        event.preventDefault();
    }).removeClass('disabled');
});

The @Devart's version is correct, but here are some improvements to avoid having error. I've edited the @Devart's answer, but it was not accepted.

SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @tables = NULL;
SELECT GROUP_CONCAT('`', table_name, '`') INTO @tables
  FROM information_schema.tables
  WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@tables,'dummy') INTO @tables;

SET @tables = CONCAT('DROP TABLE IF EXISTS ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

This script will not raise error with NULL result in case when you already deleted all tables in the database by adding at least one nonexistent - "dummy" table.

And it fixed in case when you have many tables.

And This small change to drop all view exist in the Database

SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @views = NULL;
SELECT GROUP_CONCAT('`', TABLE_NAME, '`') INTO @views
  FROM information_schema.views
  WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@views,'dummy') INTO @views;

SET @views = CONCAT('DROP VIEW IF EXISTS ', @views);
PREPARE stmt FROM @views;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

It assumes that you run the script from Database you want to delete. Or run this before:

USE REPLACE_WITH_DATABASE_NAME_YOU_WANT_TO_DELETE;

Thank you to Steve Horvath to discover the issue with backticks.

From the openssl.pc file

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: OpenSSL
Description: Secure Sockets Layer and cryptography libraries and tools
Version: 0.9.8g

You can note the Include directory path and the Libs path from this. Now your prefix for the include files is /home/username/Programming . Hence your include file option should be -I//home/username/Programming.

(Yes i got it from the comments above)

This is just to remove logs regarding the headers. You may as well provide -L<Lib path> option for linking with the -lcrypto library.

Here is what backup in this sense really means:

Android's backup service allows you to copy your persistent application data to remote "cloud" storage, in order to provide a restore point for the application data and settings. If a user performs a factory reset or converts to a new Android-powered device, the system automatically restores your backup data when the application is re-installed. This way, your users don't need to reproduce their previous data or application settings.

~Taken from http://developer.android.com/guide/topics/data/backup.html

You can register for this backup service as a developer here: https://developer.android.com/google/backup/signup.html

The type of data that can be backed up are files, databases, sharedPreferences, cache, and lib. These are generally stored in your device's /data/data/[com.myapp] directory, which is read-protected and cannot be accessed unless you have root privileges.

UPDATE: You can see this flag listed on BackupManager's api doc: BackupManager

If list

I was doing something for a list which is a set of strings and you want to remove all lines that have a certain substring you can do this

import re
def RemoveInList(sub,LinSplitUnOr):
    indices = [i for i, x in enumerate(LinSplitUnOr) if re.search(sub, x)]
    A = [i for j, i in enumerate(LinSplitUnOr) if j not in indices]
    return A

where sub is a patter that you do not wish to have in a list of lines LinSplitUnOr

for example

A=['Apple.good','Orange.good','Pear.bad','Pear.good','Banana.bad','Potato.bad']
sub = 'good'
A=RemoveInList(sub,A)

Then A will be

Here is my solution, there is no way to use momemt.js.Here is DataTable with Two DatePickers for DateRange (To and From) Filter.

$.fn.dataTable.ext.search.push(
  function (settings, data, dataIndex) {
    var min = $('#min').datepicker("getDate");
    var max = $('#max').datepicker("getDate");
    var startDate = new Date(data[4]);
    if (min == null && max == null) { return true; }
    if (min == null && startDate <= max) { return true; }
    if (max == null && startDate >= min) { return true; }
    if (startDate <= max && startDate >= min) { return true; }
    return false;
  }
);

I found my answer here:

1. Connect Android device and adb host computer to a common Wi-Fi network accessible to both. We have found that not all access points are suitable; you may need to use an access point whose firewall is configured properly to support adb.
2. Connect the device with USB cable to host.

3. Make sure adb is running in USB mode on host.

   $ adb usb
   restarting in USB mode
   

4. Connect to the device over USB.

    $ adb devices
    List of devices attached
    ######## device
   

5. Restart host adb in tcpip mode.

   $ adb tcpip 5555
   restarting in TCP mode port: 5555
   

6. Find out the IP address of the Android device: Settings -> About tablet -> Status -> IP address. Remember the IP address, of the form #.#.#.#. sometimes its not possible to find the IP-address of the android device, as in my case. so u can get it using adb as the following: $ adb shell netcfg and the should be in the last line of the result.

7. Connect adb host to device:

   $ adb connect #.#.#.#
   connected to #.#.#.#:5555
   

8. Remove USB cable from device, and confirm you can still access device:

   $ adb devices
   List of devices attached
   #.#.#.#:5555 device
   

You're now good to go!

If the adb connection is ever lost:

1. Make sure that your host is still connected to the same Wi-Fi network your Android device is.
2. Reconnect by executing the "adb connect" step again.

3. Or if that doesn't work, reset your adb host:

    adb kill-server
   

and then start over from the beginning.

Check that your dependencies were compiled without -f-nortti.

For some projects you have to set it explicitly, like in RocksDB:

USE_RTTI=1 make shared_lib -j4

The reason it is not working is because you are adding an item to the list and then overriding the whole list with a new DataSource which will clear and re-populate your list, losing the first manually added item.

So, you need to do this in reverse like this:

Status status = new Status();
DropDownList1.DataSource = status.getData();
DropDownList1.DataValueField = "ID";
DropDownList1.DataTextField = "Description";
DropDownList1.DataBind();

// Then add your first item
DropDownList1.Items.Insert(0, "Select");

With something like this:

String mDrawableName = "myappicon";
int resID = getResources().getIdentifier(mDrawableName , "drawable", getPackageName());

Update 2020

You can await setTimeout with Node.js 15 or above:

const timersPromises = require('timers/promises');

(async () => {
  const result = await timersPromises.setTimeout(2000, 'resolved')
  // Executed after 2 seconds
  console.log(result); // "resolved"
})()

Note: Stability: 1 - Use of the feature is not recommended in production environments.

Let's keep it simple. Loved @digitaldreamer 's answer but it might leave the beginners confused. So, I am going to try and simplify it.

The only HTML comment is <!-- --> It can be used as a single line comment or double, it is really up to the developer.

So, an HTML comment starts with <!-- and ends with -->. It is really that simple. You should not use any other format, to avoid any compatibility issue even if the comment format is legit or not.

This is for one liners and lovers of es6

let i= new Date().getDate 

// I can be any number, for future sake we'll use 9

const j = I % 10;
const k = I % 100;

i = `${i}${j === 1 &&  k !== 11 ? 'st' : j === 2 && k !== 12 ? 'nd' : j === 3 && k !== 13 ? 'rd' : 'th'}`}

console.log(i) //9th

Another option for +be number would be:

console.log(["st","nd","rd"][((i+90)%100-10)%10-1]||"th"]

Also to get rid of the ordinal prefix just use these:

console.log(i.parseInt("8th"))

console.log(i.parseFloat("8th"))

feel free to modify to suit you need

The ALTER TABLE statement presented by Chris should work, but first you need to declare the columns NOT NULL. All parts of a primary key need to be NOT NULL.

The radio buttons are sent on form submit when they are checked only...

use isset() if true then its checked otherwise its not

Thanks for the research FIRESTICK is a solution for non Android based but there's another one Im using if you guys want to try it let me know...

LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP, PHILCO and TOSHIBA.

Piece of cake.

Use 960Grids Go to the automatic layout builder and make a two column, fluid design. Build a left column to the width of grids that works....this is the only challenge using grids and it's very easy once you read a tutorial. In a nutshell, each column in a grid is a certain width, and you set the amount of columns you want to use. To get a column that's exactly a certain width, you have to adjust your math so that your column width is exact. Not too tough.

No chance of wrapping because others have already fought that battle for you. Compatibility back as far as you likely will ever need to go. Quick and easy....Now, download, customize and deploy.

Voila. Grids FTW.

It should be that the particular mvn command execs and does not return, thereby not executing the rest of the commands.

I understood the difference to be:

1) Concurrent - running in tandem using shared resources 2) Parallel - running side by side using different resources

So you can have two things happening at the same time independent of each other, even if they come together at points (2) or two things drawing on the same reserves throughout the operations being executed (1).

This is referred to as screen scraping, wikipedia has this article on the more specific web scraping. It can be a major challenge because there's some ugly, mess-up, broken-if-not-for-browser-cleverness HTML out there, so good luck.

From another point of view: Consider that you want to make some changes on a single String. for example you want to make the letters Uppercase and so on. you make another class named "Tools" for these actions. there is no meaning of making instance of "Tools" class because there is not any kind of entity available inside that class (compare to "Person" or "Teacher" class). So we use static keyword in order to use "Tools" class without making any instance of that, and when you press dot after class name ("Tools") you can have access to the methods you want.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(Tools.ToUpperCase("Behnoud Sherafati"));
        Console.ReadKey();
    }
}

public static class Tools
{
    public static string ToUpperCase(string str)
    {
        return str.ToUpper();

    }
}
}

The answer of crdunst is pretty neat and the best looking answer I've found but there's no explanation on how to use and the code is bigger than needed.

The only code you need:

#element {
    background-color: #cacbcf;
    text-shadow: 2px 2px 4px rgba(0,0,0, 0.5);
    filter: chroma(color=#cacbcf) progid:DXImageTransform.Microsoft.dropshadow(color=#60000000, offX=2, offY=2);
}

First you MUST specify a background-color - if your element should be transparent just copy the background-color of the parent or let it inherit. The color at the chroma-filter must match the background-color to fix those artifacts around the text (but here you must copy the color, you can't write inherit). Note that I haven't shortened the dropshadow-filter - it works but the shadows are then cut to the element dimensions (noticeable with big shadows; try to set the offsets to atleast 4).

TIP: If you want to use colors with transparency (alpha-channel) write in a #AARRGGBB notation, where AA stands for a hexadezimal value of the opacity - from 01 to FE, because FF and ironically also 00 means no transparency and is therefore useless.. ^^ Just go a little lower than in the rgba notation because the shadows aren't soft and the same alpha value would appear darker then. ;)

A nice snippet to convert the alpha value for IE (JavaScript, just paste into the console):

var number = 0.5; //alpha value from the rgba() notation
("0"+(Math.round(0.75 * number * 255).toString(16))).slice(-2);

ISSUES: The text/font behaves like an image after the shadow is applied; it gets pixelated and blurry after you zoom in... But that's IE's issue, not mine.

ffmpeg provides this functionality. All you need to do is run someting like

ffmpeg -i <inputfilename> -s 640x480 -b 512k -vcodec mpeg1video -acodec copy <outputfilename>

For newer versions of ffmpeg you need to change -b to -b:v:

ffmpeg -i <inputfilename> -s 640x480 -b:v 512k -vcodec mpeg1video -acodec copy <outputfilename>

to convert the input video file to a video with a size of 640 x 480 and a bitrate of 512 kilobits/sec using the MPEG 1 video codec and just copying the original audio stream. Of course, you can plug in any values you need and play around with the size and bitrate to achieve the quality/size tradeoff you are looking for. There are also a ton of other options described in the documentation

Run ffmpeg -formats or ffmpeg -codecs for a list of all of the available formats and codecs. If you don't have to target a specific codec for the final output, you can achieve better compression ratios with minimal quality loss using a state of the art codec like H.264.

This might work...

            from r in db.ExternalUsers select r.Name)
    }

Check for any recusive calls for methods. Mainly it is caused when there is recursive call for a method. A simple example is

public static void main(String... args) {
    Main main = new Main();

    main.testMethod(1);
}

public void testMethod(int i) {
    testMethod(i);

    System.out.println(i);
}

Here the System.out.println(i); will be repeatedly pushed to stack when the testMethod is called.

Get hrtime as single number in one line:

const begin = process.hrtime();
// ... Do the thing you want to measure
const nanoSeconds = process.hrtime(begin).reduce((sec, nano) => sec * 1e9 + nano)

Array.reduce, when given a single argument, will use the array's first element as the initial accumulator value. One could use 0 as the initial value and this would work as well, but why do the extra * 0.

There are many formats for date in SQL which are being specified. Refer https://msdn.microsoft.com/en-in/library/ms187928.aspx

Converting and comparing varchar column with selected dates.

Syntax:

SELECT * FROM tablename where CONVERT(datetime,columnname,103) 
    between '2016-03-01' and '2016-03-03'

In CONVERT(DATETIME,COLUMNNAME,103) "103" SPECIFIES THE DATE FORMAT as dd/mm/yyyy

There's a great blog post on this here:

http://www.kylejlarson.com/blog/2011/fixed-elements-and-scrolling-divs-in-ios-5/

Along with a demo here:

http://www.kylejlarson.com/files/iosdemo/

In summary, you can use the following on a div containing your main content:

.scrollable {
    position: absolute;
    top: 50px;
    left: 0;
    right: 0;
    bottom: 0;
    overflow: scroll;
    -webkit-overflow-scrolling: touch;
}

The problem I think you're describing is when you try to scroll up within a div that is already at the top - it then scrolls up the page instead of up the div and causes a bounce effect at the top of the page. I think your question is asking how to get rid of this?

In order to fix this, the author suggests that you use ScrollFix to auto increase the height of scrollable divs.

It's also worth noting that you can use the following to prevent the user from scrolling up e.g. in a navigation element:

document.addEventListener('touchmove', function(event) {
   if(event.target.parentNode.className.indexOf('noBounce') != -1 
|| event.target.className.indexOf('noBounce') != -1 ) {
    event.preventDefault(); }
}, false);

Unfortunately there are still some issues with ScrollFix (e.g. when using form fields), but the issues list on ScrollFix is a good place to look for alternatives. Some alternative approaches are discussed in this issue.

Other alternatives, also mentioned in the blog post, are Scrollability and iScroll

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

There's no history in the database itself, if you're using psql you can use "\s" to see your command history there.

You can get future queries or other types of operations into the log files by setting log_statement in the postgresql.conf file. What you probably want instead is log_min_duration_statement, which if you set it to 0 will log all queries and their durations in the logs. That can be helpful once your apps goes live, if you set that to a higher value you'll only see the long running queries which can be helpful for optimization (you can run EXPLAIN ANALYZE on the queries you find there to figure out why they're slow).

Another handy thing to know in this area is that if you run psql and tell it "\timing", it will show how long every statement after that takes. So if you have a sql file that looks like this:

\timing
select 1;

You can run it with the right flags and see each statement interleaved with how long it took. Here's how and what the result looks like:

$ psql -ef test.sql 
Timing is on.
select 1;
 ?column? 
----------
        1
(1 row)

Time: 1.196 ms

This is handy because you don't need to be database superuser to use it, unlike changing the config file, and it's easier to use if you're developing new code and want to test it out.

Just becuase your class object has no variables does not mean that it is nothing. Declaring and object and creating an object are two different things. Look and see if you are setting/creating the object.

Take for instance the dictionary object - just because it contains no variables does not mean it has not been created.

Sub test()

Dim dict As Object
Set dict = CreateObject("scripting.dictionary")

If Not dict Is Nothing Then
    MsgBox "Dict is something!"  '<--- This shows
Else
    MsgBox "Dict is nothing!"
End If

End Sub

However if you declare an object but never create it, it's nothing.

Sub test()

Dim temp As Object

If Not temp Is Nothing Then
    MsgBox "Temp is something!"
Else
    MsgBox "Temp is nothing!" '<---- This shows
End If

End Sub

Wanted to post this as a comment as a side note to the accepted answer, but that got a bit unclear. So purely as a side note:

If you have no need for the objects themselves and you want to have your project clear of further unused classes, you can parse with something like:

var list = JObject.Parse(json)["People"].Select(el => new { FirstName = (string)el["FirstName"], LastName = (string)el["LastName"] }).ToList();

var firstNames = list.Select(p => p.FirstName).ToList();
var lastNames = list.Select(p => p.LastName).ToList();

Even when using a strongly typed person class, you can still skip the root object by creating a list with JObject.Parse(json)["People"].ToObject<List<Person>>() Of course, if you do need to reuse the objects, it's better to create them from the start. Just wanted to point out the alternative ;)

I had the same problem as you do and I could solve it by following @CarlosRojas instructions with a little difference. Instead of create a new firewall rule I edited the default-allow-internal one to accept traffic from anywhere since creating new rules didn't make any difference.

sqlplus username/password@database

Eg:

sqlplus hr/hr@orcl

You have it almost done. Just explicitly say where to create the file

@echo off
  echo.>"d:\testing\dblank.txt"

This creates a file containing a blank line (CR + LF = 2 bytes).

If you want the file empty (0 bytes)

@echo off
  break>"d:\testing\dblank.txt"

Here how I solved it using Cookies:

First of all, inside the website main script:

var browserWindowSize = getCookie("_browserWindowSize");
var newSize = $(window).width() + "," + $(window).height();
var reloadForCookieRefresh = false;

if (browserWindowSize == undefined || browserWindowSize == null || newSize != browserWindowSize) {
    setCookie("_browserWindowSize", newSize, 30);
    reloadForCookieRefresh = true;
}

if (reloadForCookieRefresh)
    window.location.reload();

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

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

And inside MVC action filter:

public class SetCurrentRequestDataFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // currentRequestService is registered per web request using IoC
        var currentRequestService = iocResolver.Resolve<ICurrentRequestService>();

        if (filterContext.HttpContext.Request.Cookies.AllKeys.Contains("_browserWindowSize"))
        {
            var browserWindowSize = filterContext.HttpContext.Request.Cookies.Get("_browserWindowSize").Value.Split(',');
            currentRequestService.browserWindowWidth = int.Parse(browserWindowSize[0]);
            currentRequestService.browserWindowHeight = int.Parse(browserWindowSize[1]);
        }

    }
}

Besides all those good answers, I just want to share a good article I just read, The great primary-key debate.

Just to quote a few points:

The developer must apply a few rules when choosing a primary key for each table:

• The primary key must uniquely identify each record.
• A record’s primary-key value can’t be null.
• The primary key-value must exist when the record is created.
• The primary key must remain stable—you can’t change the primary-key field(s).
• The primary key must be compact and contain the fewest possible attributes.
• The primary-key value can’t be changed.

Natural keys (tend to) break the rules. Surrogate keys comply with the rules. (You better read through that article, it is worth your time!)

Encryption

public string EncryptString(string inputString)
{
    MemoryStream memStream = null;
    try
    {
        byte[] key = { };
        byte[] IV = { 12, 21, 43, 17, 57, 35, 67, 27 };
        string encryptKey = "aXb2uy4z"; // MUST be 8 characters
        key = Encoding.UTF8.GetBytes(encryptKey);
        byte[] byteInput = Encoding.UTF8.GetBytes(inputString);
        DESCryptoServiceProvider provider = new DESCryptoServiceProvider();
        memStream = new MemoryStream();
        ICryptoTransform transform = provider.CreateEncryptor(key, IV);
        CryptoStream cryptoStream = new CryptoStream(memStream, transform, CryptoStreamMode.Write);
        cryptoStream.Write(byteInput, 0, byteInput.Length);
        cryptoStream.FlushFinalBlock();
    }
    catch (Exception ex)
    {
        Response.Write(ex.Message);
    }
    return Convert.ToBase64String(memStream.ToArray());

        byte[] IV = { 12, 21, 43, 17, 57, 35, 67, 27 };
        string encryptKey = "aXb2uy4z"; // MUST be 8 characters
        key = Encoding.UTF8.GetBytes(encryptKey);
        byte[] byteInput = new byte[inputString.Length];
        byteInput = Convert.FromBase64String(inputString);
        DESCryptoServiceProvider provider = new DESCryptoServiceProvider();
        memStream = new MemoryStream();
        ICryptoTransform transform = provider.CreateDecryptor(key, IV);
        CryptoStream cryptoStream = new CryptoStream(memStream, transform, CryptoStreamMode.Write);
        cryptoStream.Write(byteInput, 0, byteInput.Length);
        cryptoStream.FlushFinalBlock();
    }
    catch (Exception ex)
    {
        Response.Write(ex.Message);
    }

    Encoding encoding1 = Encoding.UTF8;
    return encoding1.GetString(memStream.ToArray());
}

Replace the zeros with nan and then drop the rows with all entries as nan. After that replace nan with zeros.

import numpy as np
df = df.replace(0, np.nan)
df = df.dropna(how='all', axis=0)
df = df.replace(np.nan, 0)

Assuming you're referring to this plugin, your code should be:

// To Store
$(function() {
    $.session.set("myVar", "value");
});


// To Read
$(function() {
    alert($.session.get("myVar"));
});

Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown file, which is displayed on the project page.

In your controller you'd return an HttpStatusCodeResult like this...

[HttpPost]
public ActionResult SomeMethod(...your method parameters go here...)
{
   // todo: put your processing code here

   //If not using MVC5
   return new HttpStatusCodeResult(200);

   //If using MVC5
   return new HttpStatusCodeResult(HttpStatusCode.OK);  // OK = 200
}

Here is a very simple method which worked for me:

for (int i=0; i < 3; i++) { Toast.makeText(this, "MESSAGE", Toast.LENGTH_SHORT).show(); }

The duration of LENGTH_SHORT is 2 seconds and LENGTH_LONG is 3.5 seconds, Here the toast message will be shown for 6 Seconds since it is enclosed in a for loop. But a drawback of this method is after each 2 sec a small fading effect may arise. but it is not much noticeable. Hope it is helpful

I went through all of these answers and none of them worked for me unfortunately. However, I found this extremely simple way, after about an hour of searching : )

myView.layer.backgroundColor = CGColorCreateGenericRGB(0, 0, 0, 0.9);

Here's what worked for me:

git diff origin/master...

This shows only the changes between my currently selected local branch and the remote master branch, and ignores all changes in my local branch that came from merge commits.

If your object is not polymorphic (and a stack implementation likely isn't), then as per other answers here, what you want is the copy constructor. Please note that there are differences between copy construction and assignment in C++; if you want both behaviors (and the default versions don't fit your needs), you'll have to implement both functions.

If your object is polymorphic, then slicing can be an issue and you might need to jump through some extra hoops to do proper copying. Sometimes people use as virtual method called clone() as a helper for polymorphic copying.

Finally, note that getting copying and assignment right, if you need to replace the default versions, is actually quite difficult. It is usually better to set up your objects (via RAII) in such a way that the default versions of copy/assign do what you want them to do. I highly recommend you look at Meyer's Effective C++, especially at items 10,11,12.

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

If you want to open multiple figures, while keeping them all opened, this code worked for me:

show(block=False)
draw()

Actually, pretty much anywhere in typescript, passing a value to a function with a specified type will work as desired as long as the type being passed is compatible.

That being said, the following works...

 fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json())
      .then((res: Actor) => {
          // res is now an Actor
      });

I wanted to wrap all of my http calls in a reusable class - which means I needed some way for the client to process the response in its desired form. To support this, I accept a callback lambda as a parameter to my wrapper method. The lambda declaration accepts an any type as shown here...

callBack: (response: any) => void

But in use the caller can pass a lambda that specifies the desired return type. I modified my code from above like this...

fetch(`http://swapi.co/api/people/1/`)
  .then(res => res.json())
  .then(res => {
      if (callback) {
        callback(res);    // Client receives the response as desired type.  
      }
  });

So that a client can call it with a callback like...

(response: IApigeeResponse) => {
    // Process response as an IApigeeResponse
}

To normalize the date and eliminate the unwanted offset (tested here : https://jsfiddle.net/7xp1xL5m/ ):

var doo = new Date("2011-09-24");
console.log(  new Date( doo.getTime() + Math.abs(doo.getTimezoneOffset()*60000) )  );
// Output: Sat Sep 24 2011 00:00:00 GMT-0400 (Eastern Daylight Time)

This also accomplishes the same and credit to @tpartee (tested here : https://jsfiddle.net/7xp1xL5m/1/ ):

var doo = new Date("2011-09-24");
console.log( new Date( doo.getTime() - doo.getTimezoneOffset() * -60000 )  );

I was looking to do this also. I have a large tile (literally an image of a tile) image which I'd like to rotate by just roughly 15 degrees and have repeated. You can imagine the size of an image which would repeat seamlessly, rendering the 'image editing program' answer useless.

My solution was give the un-rotated (just one copy :) tile image to psuedo :before element - oversize it - repeat it - set the container overflow to hidden - and rotate the generated :before element using css3 transforms. Bosh!

There are almost no good reasons for not using Optional as parameters. The arguments against this rely on arguments from authority (see Brian Goetz - his argument is we can't enforce non null optionals) or that the Optional arguments may be null (essentially the same argument). Of course, any reference in Java can be null, we need to encourage rules being enforced by the compiler, not programmers memory (which is problematic and does not scale).

Functional programming languages encourage Optional parameters. One of the best ways of using this is to have multiple optional parameters and using liftM2 to use a function assuming the parameters are not empty and returning an optional (see http://www.functionaljava.org/javadoc/4.4/functionaljava/fj/data/Option.html#liftM2-fj.F-). Java 8 has unfortunately implemented a very limited library supporting optional.

As Java programmers we should only be using null to interact with legacy libraries.

According to the help of cmake:

-C <initial-cache>
     Pre-load a script to populate the cache.

     When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project.  This option may be used to specify a  file  from
     which to load cache entries before the first pass through the project's cmake listfiles.  The loaded entries take priority over the project's default values.  The given file should be a CMake
     script containing SET commands that use the CACHE option, not a cache-format file.

You make be able to create files like gcc_compiler.txt and clang_compiler.txt to includes all relative configuration in CMake syntax.

Clang Example (clang_compiler.txt):

 set(CMAKE_C_COMPILER "/usr/bin/clang" CACHE string "clang compiler" FORCE)

Then run it as

GCC:

cmake -C gcc_compiler.txt XXXXXXXX

Clang:

cmake -C clang_compiler.txt XXXXXXXX

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

datepicker doesnot have a maxDate as an option.I used this endDate option.It worked well.

> $('.demo-calendar-default').datepicker({
>                 autoHide: true,
>                 zIndex: 2048,
>                 format: 'dd/mm/yyyy',
>                 endDate: new Date()
>             });

When trying to make changes to a Pandas dataframe using a function, we use 'inplace=True' if we want to commit the changes to the dataframe. Therefore, the first line in the following code changes the name of the first column in 'df' to 'Grades'. We need to call the database if we want to see the resulting database.

df.rename(columns={0: 'Grades'}, inplace=True)
df

We use 'inplace=False' (this is also the default value) when we don't want to commit the changes but just print the resulting database. So, in effect a copy of the original database with the committed changes is printed without altering the original database.

Just to be more clear, the following codes do the same thing:

#Code 1
df.rename(columns={0: 'Grades'}, inplace=True)
#Code 2
df=df.rename(columns={0: 'Grades'}, inplace=False}

Imagine the dependency graph of packages, when the number of packages grows large, the chance of encountering a conflict when upgrading/adding packages is much higher. To avoid this, simply create a new environment in Anaconda.

Be frugal, install only what you need. For me, I installed the following packages in my new environment:

• pandas
• scikit-learn
• matplotlib
• notebook
• keras

And I have 84 packages in total.

If you like Vim, it has built-in syntax highlighting for the syslog file, e.g. it will highlight error messages in red.

vi +'syntax on' /var/log/syslog

In your code it should be

proc1.kill()

Both kill or terminate are methods of the Popen object which sends the signal signal.SIGKILL to the process.

With gawk, you can use the match function to capture parenthesized groups.

gawk 'match($0, pattern, ary) {print ary[1]}' 

example:

echo "abcdef" | gawk 'match($0, /b(.*)e/, a) {print a[1]}' 

outputs cd.

Note the specific use of gawk which implements the feature in question.

For a portable alternative you can achieve similar results with match() and substr.

example:

echo "abcdef" | awk 'match($0, /b[^e]*/) {print substr($0, RSTART+1, RLENGTH-1)}'

outputs cd.

With Hibernate 4.1.6 a new feature is introduced to handle those lazy association problems. When you enable hibernate.enable_lazy_load_no_trans property in hibernate.properties or in hibernate.cfg.xml, you will have no LazyInitializationException any more.

var result = number.ToString().Split(System.Globalization.NumberDecimalSeparator)[2]

Returns it as a string (but you can always cast that back to an int), and assumes the number does have a "." somewhere.

If you use old version of MySQL you can always use \P combined with some nice piece of awk code. Interesting example here

Isn't it exactly what you need?

You're trying to write more data than a specific column can store. Check the sizes of the data you're trying to insert against the sizes of each of the fields.

In this case transaction_status is a varchar(10) and you're trying to store 19 characters to it.

The ID of the two repos are both localSnap; that's probably not what you want and it might confuse Maven.

If that's not it: There might be more repository elements in your POM. Search the output of mvn help:effective-pom for repository to make sure the number and place of them is what you expect.

$this->db->insert_id()  

//please try this

Mongorestore has this feature of appending on top of whatever is already in the database, so this behavior could be used for combining two collections:

1. mongodump collection1
2. collection2.rename(collection1)
3. mongorestore

Didn't try it yet, but it might perform faster than the map/reduce approach.

Below are some usage examples, assuming it has been saved in a file called setenv.py somewhere in your current path. Note that in these examples i didn't have admin-rights, so the changes affected only my local user's registry tree:

if you have created UIBarButtonItem in Interface Builder and you connected outlet to item and want to bind selector programmatically.

Don't forget to set target and selector.

addAppointmentButton.action = #selector(moveToAddAppointment)
addAppointmentButton.target = self

@objc private func moveToAddAppointment() {
     self.presenter.goToCreateNewAppointment()
}

$ lsof | tree MyFold

Take a look at jfxmessagebox (http://en.sourceforge.jp/projects/jfxmessagebox/) if you are looking for very simple dialog popups.

I had to re-run git --init in an existing bare repository, and this had created a .git directory inside the bare repository tree - I realized that after typing git status there. I deleted that and everything was fine again :)

(All these answers are great, but in my case it was something completely different (as far as I can see), as described.)

   .disabled{ pointer-events: none }

will disable the click event, but not the tab event. To disable the tab event, you can set the tabindex to -1 if the disable flag is true.

<li [routerLinkActive]="['active']" [class.disabled]="isDisabled">
     <a [routerLink]="['link']" tabindex="{{isDisabled?-1:0}}" > Menu Item</a>
</li>

Moment.js will handle date formatting for you. Here is how to include it via a JavaScript tag, and then an example of how to use Moment.js to format a date.

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.14.1/moment.min.js"></script>

moment("2013-03-10T02:00:00Z").format("YYYY-MM-DD") // "2013-03-10"

You can do this either with multiple System.Net.Mail.MailAddress objects or you can provide a single string containing all of the addresses separated by commas

I really like stackPusher's ConvertToLetter function as a solution. However, in working with it I noticed several errors occurring at very specific inputs due to some flaws in the math. For example, inputting 392 returns 'N\', 418 returns 'O\', 444 returns 'P\', etc.

I reworked the function and the result produces the correct output for all input up to 703 (which is the first triple-letter column index, AAA).

Function ConvertToLetter2(iCol As Integer) As String
    Dim First As Integer
    Dim Second As Integer
    Dim FirstChar As String
    Dim SecondChar As String

    First = Int(iCol / 26)
    If First = iCol / 26 Then
        First = First - 1
    End If
    If First = 0 Then
        FirstChar = ""
    Else
        FirstChar = Chr(First + 64)
    End If

    Second = iCol Mod 26
    If Second = 0 Then
        SecondChar = Chr(26 + 64)
    Else
        SecondChar = Chr(Second + 64)
    End If

    ConvertToLetter2 = FirstChar & SecondChar

End Function

Much of this should give you compilation errors.

// note the lower case enum keyword
enum Days { Saturday, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday };

Now, Saturday, Sunday, etc. can be used as top-level bare constants,and Days can be used as a type:

Days day = Saturday;   // Days.Saturday is an error

And similarly later, to test:

if (day == Saturday)
    // ...

These enum values are like bare constants - they're un-scoped - with a little extra help from the compiler: (unless you're using C++11 enum classes) they aren't encapsulated like object or structure members for instance, and you can't refer to them as members of Days.

You'll have what you're looking for with C++11, which introduces an enum class:

enum class Days
{
    SUNDAY,
    MONDAY,
    // ... etc.
}

// ...

if (day == Days::SUNDAY)
    // ...

Note that this C++ is a little different from C in a couple of ways, one is that C requires the use of the enum keyword when declaring a variable:

// day declaration in C:
enum Days day = Saturday;
