Hidden iframes can help
It is really hard to determine if it is iso-8859-1. If you have a text with only 7 bit characters that could also be iso-8859-1 but you don't know. If you have 8 bit characters then the upper region characters exist in order encodings as well. Therefor you would have to use a dictionary to get a better guess which word it is and determine from there which letter it must be. Finally if you detect that it might be utf-8 than you are sure it is not iso-8859-1
Encoding is one of the hardest things to do because you never know if nothing is telling you

f = open('some_file.txt','r')
line_num = 0
search_phrase = "the dog barked"
for line in f.readlines():
line_num += 1
if line.find(search_phrase) >= 0:
print line_num
EDIT 1.5 years later (after seeing it get another upvote): I'm leaving this as is; but if I was writing today would write something closer to Ash/suzanshakya's solution:
def line_num_for_phrase_in_file(phrase='the dog barked', filename='file.txt')
with open(filename,'r') as f:
for (i, line) in enumerate(f):
if phrase in line:
return i
return -1
with
to open files is the pythonic idiom -- it ensures the file will be properly closed when the block using the file ends. for line in f
is much better than for line in f.readlines()
. The former is pythonic (e.g., would work if f
is any generic iterable; not necessarily a file object that implements readlines
), and more efficient f.readlines()
creates an list with the entire file in memory and then iterates through it. * if search_phrase in line
is more pythonic than if line.find(search_phrase) >= 0
, as it doesn't require line
to implement find
, reads more easily to see what's intended, and isn't easily screwed up (e.g., if line.find(search_phrase)
and if line.find(search_phrase) > 0
both will not work for all cases as find returns the index of the first match or -1). enumerate
like for i, line in enumerate(f)
than to initialize line_num = 0
before the loop and then manually increment in the loop. (Though arguably, this is more difficult to read for people unfamiliar with enumerate
.) I would reconsider trying to find out if a file exists. Instead, you should try to open it (in Standard C or C++) in the same mode you intend to use it. What use is knowing that the file exists if, say, it isn't writable when you need to use it?
This will get you the drives on the machine:
System.IO.DriveInfo.GetDrives()
These two methods will get you the bad characters to check:
System.IO.Path.GetInvalidFileNameChars();
System.IO.Path.GetInvalidPathChars();
You can catch that exception and return whatever you want from there.
open(target, 'a').close()
scores = {};
try:
with open(target, "rb") as file:
unpickler = pickle.Unpickler(file);
scores = unpickler.load();
if not isinstance(scores, dict):
scores = {};
except EOFError:
return {}
I made this like the following way:
try {
readImageInformation(new File(contentUri.getPath()));
} catch (IOException e) {
readImageInformation(new File(getRealPathFromURI(context,
contentUri)));
}
public static String getRealPathFromURI(Context context, Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver().query(contentUri, proj,
null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
So basically first I try to use a file i.e. picture taken by camera and saved on SD card. This don't work for image returned by:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
That case there is a need to convert Uri to real path by getRealPathFromURI()
function.
So the conclusion is that it depends on what type of Uri you want to convert to File.
Use an URL
instead of File
for any access that is not on your local computer.
URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
Scanner s = new Scanner(url.openStream());
Actually, URL is even more generally useful, also for local access (use a file:
URL), jar files, and about everything that one can retrieve somehow.
The way above interprets the file in your platforms default encoding. If you want to use the encoding indicated by the server instead, you have to use a URLConnection and parse it's content type, like indicated in the answers to this question.
About your Error, make sure your file compiles without any errors - you need to handle the exceptions. Click the red messages given by your IDE, it should show you a recommendation how to fix it. Do not start a program which does not compile (even if the IDE allows this).
Here with some sample exception-handling:
try {
URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
Scanner s = new Scanner(url.openStream());
// read from your scanner
}
catch(IOException ex) {
// there was some connection problem, or the file did not exist on the server,
// or your URL was not in the right format.
// think about what to do now, and put it here.
ex.printStackTrace(); // for now, simply output it.
}
I use a two parse solution as it's very easy to maintain
// Prepare the values
var allLines = (from trade in proposedTrades
select new object[]
{
trade.TradeType.ToString(),
trade.AccountReference,
trade.SecurityCodeType.ToString(),
trade.SecurityCode,
trade.ClientReference,
trade.TradeCurrency,
trade.AmountDenomination.ToString(),
trade.Amount,
trade.Units,
trade.Percentage,
trade.SettlementCurrency,
trade.FOP,
trade.ClientSettlementAccount,
string.Format("\"{0}\"", trade.Notes),
}).ToList();
// Build the file content
var csv = new StringBuilder();
allLines.ForEach(line =>
{
csv.AppendLine(string.Join(",", line));
});
File.WriteAllText(filePath, csv.ToString());
You can extend the RecursiveFilterIterator class like this:
class ExtensionFilter extends RecursiveFilterIterator
{
/**
* Hold the extensions pass to the class constructor
*/
protected $extensions;
/**
* ExtensionFilter constructor.
*
* @param RecursiveIterator $iterator
* @param string|array $extensions Extension to filter as an array ['php'] or
* as string with commas in between 'php, exe, ini'
*/
public function __construct(RecursiveIterator $iterator, $extensions)
{
parent::__construct($iterator);
$this->extensions = is_array($extensions) ? $extensions : array_map('trim', explode(',', $extensions));
}
public function accept()
{
if ($this->hasChildren()) {
return true;
}
return $this->current()->isFile() &&
in_array(strtolower($this->current()->getExtension()), $this->extensions);
}
public function getChildren()
{
return new self($this->getInnerIterator()->getChildren(), $this->extensions);
}
Now you can instantiate RecursiveDirectoryIterator with path as an argument like this:
$iterator = new RecursiveDirectoryIterator('\path\to\dir');
$iterator = new ExtensionFilter($iterator, 'xml, php, ini');
foreach($iterator as $file)
{
echo $file . '<br />';
}
This will list files under the current folder only.
To get the files in subdirectories also,
pass the $iterator ( ExtensionFIlter Iterator) to RecursiveIteratorIterator as argument:
$iterator = new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::SELF_FIRST);
Now run the foreach loop on this iterator. You will get the files with specified extension
Note:-- Also make sure to run the ExtensionFilter before RecursiveIteratorIterator, otherwise you will get all the files
The code below reads for any text files available in the directory which contains the script we are running. Then it opens every text file and stores the words of the text line into a list. After store the words we print each word line by line
import os, fnmatch
listOfFiles = os.listdir('.')
pattern = "*.txt"
store = []
for entry in listOfFiles:
if fnmatch.fnmatch(entry, pattern):
_fileName = open(entry,"r")
if _fileName.mode == "r":
content = _fileName.read()
contentList = content.split(" ")
for i in contentList:
if i != '\n' and i != "\r\n":
store.append(i)
for i in store:
print(i)
I think its worth referencing this similar answer: https://stackoverflow.com/a/5288804/64313
Here is a another quick solution. There are other variations possible on this using the <available>
tag:
# exit with failure if no files are found
<property name="file" value="${some.path}/some.txt" />
<fail message="FILE NOT FOUND: ${file}">
<condition><not>
<available file="${file}" />
</not></condition>
</fail>
If you are using C function fgetc
then you should check a next character whether it is equal to the new line character or to EOF. For example
unsigned int count = 0;
while ( 1 )
{
int c = fgetc( FileStream );
if ( c == EOF || c == '\n' )
{
printF( "The length of the line is %u\n", count );
count = 0;
if ( c == EOF ) break;
}
else
{
++count;
}
}
or maybe it would be better to rewrite the code using do-while loop. For example
unsigned int count = 0;
do
{
int c = fgetc( FileStream );
if ( c == EOF || c == '\n' )
{
printF( "The length of the line is %u\n", count );
count = 0;
}
else
{
++count;
}
} while ( c != EOF );
Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc
to read lines of a file.
But if the program is written in C++ then it would be much better if you would use std::ifstream
and std::string
classes and function std::getline
to read a whole line.
To be certain that a folder exists (and not a file) I use this function:
Public Function FolderExists(strFolderPath As String) As Boolean
On Error Resume Next
FolderExists = ((GetAttr(strFolderPath) And vbDirectory) = vbDirectory)
On Error GoTo 0
End Function
It works both, with \
at the end and without.
When you run a jar, your Main class itself becomes args[0] and your filename comes immediately after.
I had the same issue: I could locate my file when provided the absolute path from eclipse (because I was referring to the file as args[0]). Yet when I run the same from jar, it was trying to locate my main class - which is when I got the idea that I should be reading my file from args[1].
Use FileUtils.writeStringToFile()
from Apache Commons IO. No need to reinvent this particular wheel.
Since Java 8, you can do that in three lines:
try (Stream<Path> files = Files.list(Paths.get("your/path/here"))) {
long count = files.count();
}
Regarding the 5000 child nodes and inode aspects:
This method will iterate over the entries but as Varkhan suggested you probably can't do better besides playing with JNI or direct system commands calls, but even then, you can never be sure these methods don't do the same thing!
However, let's dig into this a little:
Looking at JDK8 source, Files.list
exposes a stream that uses an Iterable
from Files.newDirectoryStream
that delegates to FileSystemProvider.newDirectoryStream
.
On UNIX systems (decompiled sun.nio.fs.UnixFileSystemProvider.class
), it loads an iterator: A sun.nio.fs.UnixSecureDirectoryStream
is used (with file locks while iterating through the directory).
So, there is an iterator that will loop through the entries here.
Now, let's look to the counting mechanism.
The actual count is performed by the count/sum reducing API exposed by Java 8 streams. In theory, this API can perform parallel operations without much effort (with multihtreading). However the stream is created with parallelism disabled so it's a no go...
The good side of this approach is that it won't load the array in memory as the entries will be counted by an iterator as they are read by the underlying (Filesystem) API.
Finally, for the information, conceptually in a filesystem, a directory node is not required to hold the number of the files that it contains, it can just contain the list of it's child nodes (list of inodes). I'm not an expert on filesystems, but I believe that UNIX filesystems work just like that. So you can't assume there is a way to have this information directly (i.e: there can always be some list of child nodes hidden somewhere).
You can stop the 2-line separation in the output by using
with open('t.ini') as f:
for line in f:
print line.strip()
if 'str' in line:
break
To avoid getting "database or disk is full" in the first place, try this if you have lots of RAM:
sqlite> pragma temp_store = 2;
That tells SQLite to put temp files in memory. (The "database or disk is full" message does not mean either that the database is full or that the disk is full! It means the temp directory is full.) I have 256G of RAM but only 2G of /tmp, so this works great for me. The more RAM you have, the bigger db files you can work with.
If you haven't got a lot of ram, try this:
sqlite> pragma temp_store = 1;
sqlite> pragma temp_store_directory = '/directory/with/lots/of/space';
temp_store_directory is deprecated (which is silly, since temp_store is not deprecated and requires temp_store_directory), so be wary of using this in code.
If the file contains text data, a technique I use is to put the text into a textarea element and have the user select it (click in textarea then ctrl-A) then copy followed by a paste to a text editor.
Just add another way , in normal mode , type ctrl+v
then G
, select the rest, then D
, I don't think it is effective , you should do like @Ed Guiness, head -n 20 > filename in linux.
Command line usage:
for /f %f in ('dir /b c:\') do echo %f
Batch file usage:
for /f %%f in ('dir /b c:\') do echo %%f
Update: if the directory contains files with space in the names, you need to change the delimiter the for /f
command is using. for example, you can use the pipe char.
for /f "delims=|" %%f in ('dir /b c:\') do echo %%f
Update 2: (quick one year and a half after the original answer :-)) If the directory name itself has a space in the name, you can use the usebackq
option on the for
:
for /f "usebackq delims=|" %%f in (`dir /b "c:\program files"`) do echo %%f
And if you need to use output redirection or command piping, use the escape char (^
):
for /f "usebackq delims=|" %%f in (`dir /b "c:\program files" ^| findstr /i microsoft`) do echo %%f
There is no need to write lots of code. Even it can be done just by one line of code. See here
Below is the one line code that returns the filename only and removes extension name:
<?php
echo pathinfo('logo.png')['filename'];
?>
It will print
logo
I'd try something like this.
try:
f = open(filePath)
except IOError:
print "No such file: %s" % filePath
raw_input("Press Enter to close window")
try:
lines = f.readlines()
while True:
line = f.readline()
try:
if not line:
time.sleep(1)
else:
functionThatAnalisesTheLine(line)
except Exception, e:
# handle the exception somehow (for example, log the trace) and raise the same exception again
raw_input("Press Enter to close window")
raise e
finally:
f.close()
The loop checks if there is a new line(s) since last time file was read - if there is, it's read and passed to the functionThatAnalisesTheLine
function. If not, script waits 1 second and retries the process.
It is possible. You can have the download started from inside an ajax function, for example, just after the .csv file is created.
I have an ajax function that exports a database of contacts to a .csv file, and just after it finishes, it automatically starts the .csv file download. So, after I get the responseText and everything is Ok, I redirect browser like this:
window.location="download.php?filename=export.csv";
My download.php file looks like this:
<?php
$file = $_GET['filename'];
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=".$file."");
header("Content-Transfer-Encoding: binary");
header("Content-Type: binary/octet-stream");
readfile($file);
?>
There is no page refresh whatsoever and the file automatically starts downloading.
NOTE - Tested in the following browsers:
Chrome v37.0.2062.120
Firefox v32.0.1
Opera v12.17
Internet Explorer v11
@jing: "The DirectoryInfo solution is much faster then this (especially for network path)"
I cant confirm this. It seems as if Directory.GetFiles triggers a filesystem or network cache. The first request takes a while, but the following requests are much faster, even if new files were added. In my test I did a Directory.getfiles and a info.GetFiles with the same patterns and both run equally
GetFiles done 437834 in00:00:20.4812480
process files done 437834 in00:00:00.9300573
GetFiles by Dirinfo(2) done 437834 in00:00:20.7412646

I used the following code to create a temporary file for writing bytes. And its working fine.
File file = new File(Environment.getExternalStorageDirectory() + "/" + File.separator + "test.txt");
file.createNewFile();
byte[] data1={1,1,0,0};
//write the bytes in file
if(file.exists())
{
OutputStream fo = new FileOutputStream(file);
fo.write(data1);
fo.close();
System.out.println("file created: "+file);
}
//deleting the file
file.delete();
System.out.println("file deleted");
You can use the File.WriteAllText method.
System.IO.File.WriteAllText(@"Path/foo.bar",string.Empty);
Also CON, PRN, AUX, NUL, COM# and a few others are never legal filenames in any directory with any extension.
I got it worked with this command curl -F 'filename=@/home/yourhomedirextory/file.txt' http://yourserver/upload
You can't commit empty folders in git. If you want it to show up, you need to put something in it, even just an empty file.
For example, add an empty file called .gitkeep
to the folder you want to keep, then in your .gitignore
file write:
# exclude everything
somefolder/*
# exception to the rule
!somefolder/.gitkeep
Commit your .gitignore
and .gitkeep
files and this should resolve your issue.
what worked for me was and is superfast is
import pandas as pd
import dask.dataframe as dd
import time
t=time.clock()
df_train = dd.read_csv('../data/train.csv', usecols=[col1, col2])
df_train=df_train.compute()
print("load train: " , time.clock()-t)
Another working solution is:
import pandas as pd
from tqdm import tqdm
PATH = '../data/train.csv'
chunksize = 500000
traintypes = {
'col1':'category',
'col2':'str'}
cols = list(traintypes.keys())
df_list = [] # list to hold the batch dataframe
for df_chunk in tqdm(pd.read_csv(PATH, usecols=cols, dtype=traintypes, chunksize=chunksize)):
# Can process each chunk of dataframe here
# clean_data(), feature_engineer(),fit()
# Alternatively, append the chunk to list and merge all
df_list.append(df_chunk)
# Merge all dataframes into one dataframe
X = pd.concat(df_list)
# Delete the dataframe list to release memory
del df_list
del df_chunk
You use separator when you are building a file path. So in unix the separator is /
. So if you wanted to build the unix path /var/temp
you would do it like this:
String path = File.separator + "var"+ File.separator + "temp"
You use the pathSeparator
when you are dealing with a list of files like in a classpath. For example, if your app took a list of jars as argument the standard way to format that list on unix is: /path/to/jar1.jar:/path/to/jar2.jar:/path/to/jar3.jar
So given a list of files you would do something like this:
String listOfFiles = ...
String[] filePaths = listOfFiles.split(File.pathSeparator);
I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.
There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can
Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)
Loop with %c to read the stream character by character instead of %d.
You can react to new file activity with FileSystemWatcher.
A simple Stream extension method would do the job:
public static class StreamExtensions
{
public static string ConvertToBase64(this Stream stream)
{
var bytes = new Byte[(int)stream.Length];
stream.Seek(0, SeekOrigin.Begin);
stream.Read(bytes, 0, (int)stream.Length);
return Convert.ToBase64String(bytes);
}
}
The methods for Read (and also Write) and optimized for the respective class (whether is file stream, memory stream, etc.) and will do the work for you. For simple task like this, there is no need of readers, and etc.
The only drawback is that the stream is copied into byte array, but that is how the conversion to base64 via Convert.ToBase64String works unfortunately.
Another, unfortunately highly OS-dependent, solution is memory mapping the file. The benefits generally include performance of the read, and reduced memory use as the applications view and operating systems file cache can actually share the physical memory.
POSIX code would look like this:
int fd = open("filename", O_RDONLY);
int len = lseek(fd, 0, SEEK_END);
void *data = mmap(0, len, PROT_READ, MAP_PRIVATE, fd, 0);
Windows on the other hand is little more tricky, and unfortunately I don't have a compiler in front of me to test, but the functionality is provided by CreateFileMapping()
and MapViewOfFile()
.
How about below:
FileReader fileReader = new FileReader(new File("test.txt"));
BufferedReader br = new BufferedReader(fileReader);
String line = null;
// if no more lines the readLine() returns null
while ((line = br.readLine()) != null) {
// reading lines until the end of the file
}
Source: http://devmain.blogspot.co.uk/2013/10/java-quick-way-to-read-or-write-to-file.html
header("Content-Type: application/octet-stream");
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"file.exe\"");
echo readfile($url);
is correct
or better one for exe type of files
header("Location: $url");
The t
indicates text mode, meaning that \n
characters will be translated to the host OS line endings when writing to a file, and back again when reading. The flag is basically just noise, since text mode is the default.
Other than U
, those mode flags come directly from the standard C library's fopen()
function, a fact that is documented in the sixth paragraph of the python2 documentation for open()
.
As far as I know, t
is not and has never been part of the C standard, so although many implementations of the C library accept it anyway, there's no guarantee that they all will, and therefore no guarantee that it will work on every build of python. That explains why the python2 docs didn't list it, and why it generally worked anyway. The python3 docs make it official.
You can create an empty file whether it exists or not ...
new FileOutputStream("score.txt", false).close();
if you want to leave the file if it exists ...
new FileOutputStream("score.txt", true).close();
You will only get a FileNotFoundException if you try to create the file in a directory which doesn't exist.
import os
path = chap_name
if not os.path.exists(path):
os.makedirs(path)
filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
temp_file.write(buff)
Key point is to use os.makedirs
in place of os.mkdir
. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html
Open the file in binary mode as you are storing binary (jpeg) data.
In response to Edit 2, if img_alt sometimes has '/' in it:
img_alt = os.path.basename(img_alt)

r+
is the canonical mode for reading and writing at the same time. This is not different from using the fopen()
system call since file()
/ open()
is just a tiny wrapper around this operating system call.
Here you can Find some other way to do the same.
Read file.
File file1 = new File("C:\Build\myfolder\myTestfile.txt");
def String yourData = file1.readLines();
Read Full file.
File file1 = new File("C:\Build\myfolder\myfile.txt");
def String yourData= file1.getText();
Read file Line Bye Line.
File file1 = new File("C:\Build\myfolder\myTestfile.txt");
for (def i=0;i<=30;i++) // specify how many line need to read eg.. 30
{
log.info file1.readLines().get(i)
}
Create a new file.
new File("C:\Temp\FileName.txt").createNewFile();
Here is a simple work around for white space between the '=' sign and the data, in the config file. Assign to the istringstream from the location after the '=' sign and when reading from it, any leading white space is ignored.
Note: while using an istringstream in a loop, make sure you call clear() before assigning a new string to it.
//config.txt
//Input name = image1.png
//Num. of rows = 100
//Num. of cols = 150

I'm not sure I understand you completely, but if you wish to get the absolute file path provided that you know the relative file name, you can always do this:
System.out.println("File path: " + new File("Your file name").getAbsolutePath());
The File class has several more methods you might find useful.
Working Code:
just hide input part and do like this.
<div class="ImageUpload">
<label for="FileInput">
<img src="../../img/Upload_Panel.png" style="width: 18px; margin-top: -316px; margin-left: 900px;"/>
</label>
<input id="FileInput" type="file" onchange="readURL(this,'Picture')" style="cursor: pointer; display: none"/>
</div>
Try making
NSString *appFile = [documentsDirectory stringByAppendingPathComponent:@"MyFile"];
as
NSString *appFile = [documentsDirectory stringByAppendingPathComponent:@"MyFile.txt"];
I guess there are so many ways to make what you want. Here's a way that I use. With the commons.io
library you can iterate over the files in a directory. You must use the FileUtils.iterateFiles
method and you can process each file.
You can find the information here: http://commons.apache.org/proper/commons-io/download_io.cgi
Here's an example:
Iterator it = FileUtils.iterateFiles(new File("C:/"), null, false);
while(it.hasNext()){
System.out.println(((File) it.next()).getName());
}
You can change null
and put a list of extentions if you wanna filter. Example: {".xml",".java"}
What do you think about this approach?
with open(filename) as data:
datalines = (line.rstrip('\r\n') for line in data)
for line in datalines:
...do something awesome...
Generator expression avoids loading whole file into memory and with
ensures closing the file
If there are no spaces in paths, and you are interested, like I was, in files of specific extension only, you can use
git checkout otherBranch -- $(git ls-tree --name-only -r otherBranch | egrep '*.java')
If you want to upload a single file with Python requests
library, then requests lib supports streaming uploads, which allow you to send large files or streams without reading into memory.
with open('massive-body', 'rb') as f:
requests.post('http://some.url/streamed', data=f)
Then store the file on the server.py
side such that save the stream into file without loading into the memory. Following is an example with using Flask file uploads.
@app.route("/upload", methods=['POST'])
def upload_file():
from werkzeug.datastructures import FileStorage
FileStorage(request.stream).save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
return 'OK', 200
Or use werkzeug Form Data Parsing as mentioned in a fix for the issue of "large file uploads eating up memory" in order to avoid using memory inefficiently on large files upload (s.t. 22 GiB file in ~60 seconds. Memory usage is constant at about 13 MiB.).
@app.route("/upload", methods=['POST'])
def upload_file():
def custom_stream_factory(total_content_length, filename, content_type, content_length=None):
import tempfile
tmpfile = tempfile.NamedTemporaryFile('wb+', prefix='flaskapp', suffix='.nc')
app.logger.info("start receiving file ... filename => " + str(tmpfile.name))
return tmpfile
import werkzeug, flask
stream, form, files = werkzeug.formparser.parse_form_data(flask.request.environ, stream_factory=custom_stream_factory)
for fil in files.values():
app.logger.info(" ".join(["saved form name", fil.name, "submitted as", fil.filename, "to temporary file", fil.stream.name]))
# Do whatever with stored file at `fil.stream.name`
return 'OK', 200
As others suggested, you can serialize and deserialize the whole list at once, which is simpler and seems to comply perfectly with what you intend to do.
In that case the serialization code becomes
ObjectOutputStream oos = null;
FileOutputStream fout = null;
try{
fout = new FileOutputStream("G:\\address.ser", true);
oos = new ObjectOutputStream(fout);
oos.writeObject(myClassList);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if(oos != null){
oos.close();
}
}
And deserialization becomes (assuming that myClassList is a list and hoping you will use generics):
ObjectInputStream objectinputstream = null;
try {
FileInputStream streamIn = new FileInputStream("G:\\address.ser");
objectinputstream = new ObjectInputStream(streamIn);
List<MyClass> readCase = (List<MyClass>) objectinputstream.readObject();
recordList.add(readCase);
System.out.println(recordList.get(i));
} catch (Exception e) {
e.printStackTrace();
} finally {
if(objectinputstream != null){
objectinputstream .close();
}
}
You can also deserialize several objects from a file, as you intended to:
ObjectInputStream objectinputstream = null;
try {
streamIn = new FileInputStream("G:\\address.ser");
objectinputstream = new ObjectInputStream(streamIn);
MyClass readCase = null;
do {
readCase = (MyClass) objectinputstream.readObject();
if(readCase != null){
recordList.add(readCase);
}
} while (readCase != null)
System.out.println(recordList.get(i));
} catch (Exception e) {
e.printStackTrace();
} finally {
if(objectinputstream != null){
objectinputstream .close();
}
}
Please do not forget to close stream objects in a finally clause (note: it can throw exception).
EDIT
As suggested in the comments, it should be preferable to use try with resources and the code should get quite simpler.
Here is the list serialization :
try(
FileOutputStream fout = new FileOutputStream("G:\\address.ser", true);
ObjectOutputStream oos = new ObjectOutputStream(fout);
){
oos.writeObject(myClassList);
} catch (Exception ex) {
ex.printStackTrace();
}
ls -l --block-size=M will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB.
If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.
If you don't want the M suffix attached to the file size, you can use something like --block-size=1M. Thanks Stéphane Chazelas for suggesting this.
This is described in the man page for ls; man ls and search for SIZE. It allows for units other than MB/MiB as well, and from the looks of it (I didn't try that) arbitrary block sizes as well (so you could see the file size as number of 412-byte blocks, if you want to).
Note that the --block-size parameter is a GNU extension on top of the Open Group's ls, so this may not work if you don't have a GNU userland (which most Linux installations do). The ls from GNU coreutils 8.5 does support --block-size as described above.
You should use the csv
module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.
import csv
with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
tsvin = csv.reader(tsvin, delimiter='\t')
csvout = csv.writer(csvout)
for row in tsvin:
count = int(row[4])
if count > 0:
csvout.writerows([row[2:4] for _ in range(count)])
or, using the itertools
module to do the repeating with itertools.repeat()
:
from itertools import repeat
import csv
with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
tsvin = csv.reader(tsvin, delimiter='\t')
csvout = csv.writer(csvout)
for row in tsvin:
count = int(row[4])
if count > 0:
csvout.writerows(repeat(row[2:4], count))
When you want your include to know what file it is in (ie. what script name was actually requested), use:
basename($_SERVER["SCRIPT_FILENAME"], '.php')
Because when you are writing to a file you usually know its name.
Edit: As noted by Alec Teal, if you use symlinks it will show the symlink name instead.
Try this:
<SCRIPT LANGUAGE="JavaScript">
function WriteToFile(passForm) {
set fso = CreateObject("Scripting.FileSystemObject");
set s = fso.CreateTextFile("C:\test.txt", True);
s.writeline("HI");
s.writeline("Bye");
s.writeline("-----------------------------");
s.Close();
}
</SCRIPT>
</head>
<body>
<p>To sign up for the Excel workshop please fill out the form below:
</p>
<form onSubmit="WriteToFile(this)">
Type your first name:
<input type="text" name="FirstName" size="20">
<br>Type your last name:
<input type="text" name="LastName" size="20">
<br>
<input type="submit" value="submit">
</form>
This will work only on IE
import sys
print sys.path[0]
this would print the path of the currently executing script

I use the following, it also tests the extension which means it can be used for testing if the path supplied is a file but a file that doesn't exist.
private static bool isDirectory(string path)

if (fileTest.Exists == true)

This is so called file local variables, that are understood by Emacs and set correspondingly. See corresponding section in Emacs manual - you can define them either in header or in footer of file
Javascript has a FileSystem API. If you can deal with having the feature only work in Chrome, a good starting point would be: http://www.html5rocks.com/en/tutorials/file/filesystem/.
import os
[val for sublist in [[os.path.join(i[0], j) for j in i[2]] for i in os.walk('./')] for val in sublist]
# Meta comment to ease selecting text
The outer most val for sublist in ...
loop flattens the list to be one dimensional. The j
loop collects a list of every file basename and joins it to the current path. Finally, the i
loop iterates over all directories and sub directories.
This example uses the hard-coded path ./
in the os.walk(...)
call, you can supplement any path string you like.
Note: os.path.expanduser
and/or os.path.expandvars
can be used for paths strings like ~/
Its easy to add in file basename tests and directoryname tests.
For Example, testing for *.jpg
files:
... for j in i[2] if j.endswith('.jpg')] ...
Additionally, excluding the .git
directory:
... for i in os.walk('./') if '.git' not in i[0].split('/')]
Use filectime. For Windows it will return the creation time, and for Unix the change time which is the best you can get because on Unix there is no creation time (in most filesystems).
Note also that in some Unix texts the ctime of a file is referred to as being the creation time of the file. This is wrong. There is no creation time for Unix files in most Unix filesystems.
I use the timestamp
i.e
new File( simpleDateFormat.format( new Date() ) );
And have the simpleDateFormat initialized to something like as:
new SimpleDateFormat("File-ddMMyy-hhmmss.SSS.txt");
EDIT
What about
new File(String.format("%s.%s", sdf.format( new Date() ),
random.nextInt(9)));
Unless the number of files created in the same second is too high.
If that's the case and the name doesn't matters
new File( "file."+count++ );
:P
[]byte
is a slice (similar to a substring) of all or part of a byte array. Think of the slice as a value structure with a hidden pointer field for the system to locate and access all or part of an array (the slice), plus fields for the length and capacity of the slice, which you can access using the len()
and cap()
functions.
Here's a working starter kit for you, which reads and prints a binary file; you will need to change the inName
literal value to refer to a small file on your system.
package main
import (
"fmt";
"os";
)
func main()
{
inName := "file-rw.bin";
inPerm := 0666;
inFile, inErr := os.Open(inName, os.O_RDONLY, inPerm);
if inErr == nil {
inBufLen := 16;
inBuf := make([]byte, inBufLen);
n, inErr := inFile.Read(inBuf);
for inErr == nil {
fmt.Println(n, inBuf[0:n]);
n, inErr = inFile.Read(inBuf);
}
}
inErr = inFile.Close();
}
opendir/readdir are POSIX. If POSIX is not enough for the portability you want to achieve, check Apache Portable Runtime
If you are not using the transferTo feature or non-blocking features you will not notice a difference between traditional IO and NIO(2) because the traditional IO maps to NIO.
But if you can use the NIO features like transferFrom/To or want to use Buffers, then of course NIO is the way to go.
Another alternative approach is:
How do I create a Java string from the contents of a file?
Other option is to use utilities provided open source libraries
http://commons.apache.org/io/api-1.4/index.html?org/apache/commons/io/IOUtils.html
Why java doesn't provide such a common util API ?
a) to keep the APIs generic so that encoding, buffering etc is handled by the programmer.
b) make programmers do some work and write/share opensource util libraries :D ;-)
This concerns Java versions 7 and earlier.
To quote a good answer to the same question:
If you want it back as a string later, you can call getPath(). Indeed, if you really wanted to mimic Path.Combine, you could just write something like:
public static String combine (String path1, String path2) {
File file1 = new File(path1);
File file2 = new File(file1, path2);
return file2.getPath();
}
I just saw this test:
bool getFileExists(const TCHAR *file)
{
return (GetFileAttributes(file) != 0xFFFFFFFF);
}
I had the exact same problem. Here is the solution that worked for me: simply put your properties file path in the cmd line this way :
-Dlog4j.configuration=<FILE_PATH> (ex: log4j.properties)
Hope this will help you
There's also a practical programming issue with files lacking newlines at the end: The read
Bash built-in (I don't know about other read
implementations) doesn't work as expected:
printf $'foo\nbar' | while read line
do
echo $line
done
This prints only foo
! The reason is that when read
encounters the last line, it writes the contents to $line
but returns exit code 1 because it reached EOF. This breaks the while
loop, so we never reach the echo $line
part. If you want to handle this situation, you have to do the following:
while read line || [ -n "${line-}" ]
do
echo $line
done < <(printf $'foo\nbar')
That is, do the echo
if the read
failed because of a non-empty line at end of file. Naturally, in this case there will be one extra newline in the output which was not in the input.
Note that what you want is to know if stdin is connected to a terminal or not, not if it exists. It always exists but when you use the shell to pipe something into it or read a file, it is not connected to a terminal.
You can check that a file descriptor is connected to a terminal via the termios.h functions:
#include <termios.h>
#include <stdbool.h>
bool stdin_is_a_pipe(void)
{
struct termios t;
return (tcgetattr(STDIN_FILENO, &t) < 0);
}
This will try to fetch the terminal attributes of stdin. If it is not connected to a pipe, it is attached to a tty and the tcgetattr function call will succeed. In order to detect a pipe, we check for tcgetattr failure.
I see you've found your answer, however it didn't work for me. Delete kept returning false, so I tried the following and it worked (For anybody else for whom the chosen answer didn't work):
System.out.println(new File(path).getAbsoluteFile().delete());
The System out can be ignored obviously, I put it for convenience of confirming the deletion.

I'm assuming you have fromPath (an absolute path for a folder), and toPath (an absolute path for a folder/file), and your're looking for a path that with represent the file/folder in toPath as a relative path from fromPath (your current working directory is fromPath) then something like this should work:
public static String getRelativePath(String fromPath, String toPath) {
// This weirdness is because a separator of '/' messes with String.split()
String regexCharacter = File.separator;
if (File.separatorChar == '\\') {
regexCharacter = "\\\\";
}
String[] fromSplit = fromPath.split(regexCharacter);
String[] toSplit = toPath.split(regexCharacter);
// Find the common path
int common = 0;
while (fromSplit[common].equals(toSplit[common])) {
common++;
}
StringBuffer result = new StringBuffer(".");
// Work your way up the FROM path to common ground
for (int i = common; i < fromSplit.length; i++) {
result.append(File.separatorChar).append("..");
}
// Work your way down the TO path
for (int i = common; i < toSplit.length; i++) {
result.append(File.separatorChar).append(toSplit[i]);
}
return result.toString();
}
Under NT-style cmd.exe, you can loop through the lines of a text file with
FOR /F %i IN (file.txt) DO @echo %i
Type "help for" on the command prompt for more information. (don't know if that works in whatever "DOS" you are using)
A cleaner approach:
function Size($path)
{
$bytes = sprintf('%u', filesize($path));
if ($bytes > 0)
{
$unit = intval(log($bytes, 1024));
$units = array('B', 'KB', 'MB', 'GB');
if (array_key_exists($unit, $units) === true)
{
return sprintf('%d %s', $bytes / pow(1024, $unit), $units[$unit]);
}
}
return $bytes;
}
import java.io.File;
public class Test {
public static void main( String [] args ) {
File actual = new File(".");
for( File f : actual.listFiles()){
System.out.println( f.getName() );
}
}
}
It displays indistinctly files and folders.

Samsung file explorer needs not only custom action (com.sec.android.app.myfiles.PICK_DATA), but also category part (Intent.CATEGORY_DEFAULT) and mime-type should be passed as extra.
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
intent.addCategory(Intent.CATEGORY_DEFAULT);
You can also use this action for opening multiple files: com.sec.android.app.myfiles.PICK_DATA_MULTIPLE Anyway here is my solution which works on Samsung and other devices:
public void openFile(String mimeType) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(mimeType);
intent.addCategory(Intent.CATEGORY_OPENABLE);
// special intent for Samsung file manager
Intent sIntent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
// if you want any file type, you can skip next line
sIntent.putExtra("CONTENT_TYPE", mimeType);
sIntent.addCategory(Intent.CATEGORY_DEFAULT);
Intent chooserIntent;
if (getPackageManager().resolveActivity(sIntent, 0) != null){
// it is device with Samsung file manager
chooserIntent = Intent.createChooser(sIntent, "Open file");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { intent});
} else {
chooserIntent = Intent.createChooser(intent, "Open file");
}
try {
startActivityForResult(chooserIntent, CHOOSE_FILE_REQUESTCODE);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(getApplicationContext(), "No suitable File Manager was found.", Toast.LENGTH_SHORT).show();
}
}
This solution works well for me, and maybe will be useful for someone else.
Logging to stdout
and rotating file
with different levels and formats:
import logging
import logging.handlers
import sys
if __name__ == "__main__":
# Change root logger level from WARNING (default) to NOTSET in order for all messages to be delegated.
logging.getLogger().setLevel(logging.NOTSET)
# Add stdout handler, with level INFO
console = logging.StreamHandler(sys.stdout)
console.setLevel(logging.INFO)
formater = logging.Formatter('%(name)-13s: %(levelname)-8s %(message)s')
console.setFormatter(formater)
logging.getLogger().addHandler(console)
# Add file rotating handler, with level DEBUG
rotatingHandler = logging.handlers.RotatingFileHandler(filename='rotating.log', maxBytes=1000, backupCount=5)
rotatingHandler.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
rotatingHandler.setFormatter(formatter)
logging.getLogger().addHandler(rotatingHandler)
log = logging.getLogger("app." + __name__)
log.debug('Debug message, should only appear in the file.')
log.info('Info message, should appear in file and stdout.')
log.warning('Warning message, should appear in file and stdout.')
log.error('Error message, should appear in file and stdout.')
With C++17 you can use std::filesystem::is_directory
function (https://en.cppreference.com/w/cpp/filesystem/is_directory). It accepts a std::filesystem::path
object which can be constructed with a unicode path.
Do you mean catch an Exception
of any type that is thrown, as opposed to just specific Exceptions?
If so:
try {
//...file IO...
} catch(Exception e) {
//...do stuff with e, such as check its type or log it...
}
If reading the whole file is acceptable then use a deque.
from collections import deque
deque(f, maxlen=n)
Prior to 2.6, deques didn't have a maxlen option, but it's easy enough to implement.
import itertools
def maxque(items, size):
items = iter(items)
q = deque(itertools.islice(items, size))
for item in items:
del q[0]
q.append(item)
return q
If it's a requirement to read the file from the end, then use a gallop (a.k.a exponential) search.
def tail(f, n):
assert n >= 0
pos, lines = n+1, []
while len(lines) <= n:
try:
f.seek(-pos, 2)
except IOError:
f.seek(0)
break
finally:
lines = list(f)
pos *= 2
return lines[-n:]
Use permission symbols instead of numbers
Your problem would have been avoided if you had used the more semantically named permission symbols rather than raw magic numbers, e.g. for 664
:
#!/usr/bin/env python3
import os
import stat
os.chmod(
'myfile',
stat.S_IRUSR |
stat.S_IWUSR |
stat.S_IRGRP |
stat.S_IWGRP |
stat.S_IROTH
)
This is documented at https://docs.python.org/3/library/os.html#os.chmod and the names are the same as the POSIX C API values documented at man 2 stat
.
Another advantage is the greater portability as mentioned in the docs:
Note: Although Windows supports
chmod()
, you can only set the file’s read-only flag with it (via thestat.S_IWRITE
andstat.S_IREAD
constants or a corresponding integer value). All other bits are ignored.
chmod +x
is demonstrated at: How do you do a simple "chmod +x" from within python?

Okay, first intuition is here:
handlers = java.util.logging.FileHandler, java.util.logging.ConsoleHandler
.level = ALL
The Java prop file parser isn't all that smart, I'm not sure it'll handle this. But I'll go look at the docs again....
In the mean time, try:
handlers = java.util.logging.FileHandler
java.util.logging.ConsoleHandler.level = ALL
Update
No, duh, needed more coffee. Nevermind.
While I think more, note that you can use the methods in Properties to load and print a prop-file: it might be worth writing a minimal program to see what java thinks it reads in that file.
Another update
This line:
FileInputStream configFile = new FileInputStream("/path/to/app.properties"));
has an extra end-paren. It won't compile. Make sure you're working with the class file you think you are.

The term business logic is in my opinion not a precise definition. Evans talks in his book, Domain Driven Design, about two types of business logic:
This separation is in my opinion a lot clearer. And with the realization that there are different types of business rules also comes the realization that they don't all necessarily go the same place.
Domain logic is logic that corresponds to the actual domain. So if you are creating an accounting application, then domain rules would be rules regarding accounts, postings, taxation, etc. In an agile software planning tool, the rules would be stuff like calculating release dates based on velocity and story points in the backlog, etc.
For both these types of application, CSV import/export could be relevant, but the rules of CSV import/export has nothing to do with the actual domain. This kind of logic is application logic.
Domain logic most certainly goes into the model layer. The model would also correspond to the domain layer in DDD.
Application logic however does not necessarily have to be placed in the model layer. That could be placed in the controllers directly, or you could create a separate application layer hosting those rules. What is most logical in this case would depend on the actual application.
This appears to be a UTF-8 encoding issue that may have been caused by a double-UTF8-encoding of the database file contents.
This situation could happen due to factors such as the character set that was or was not selected (for instance when a database backup file was created) and the file format and encoding database file was saved with.
I have seen these strange UTF-8 characters in the following scenario (the description may not be entirely accurate as I no longer have access to the database in question):
Looking into the file contents:
So, the issue is that "false" (UTF8-encoded twice) utf-8 needs to be converted back into "correct" utf-8 (only UTF8-encoded once).
Trying to fix this in PHP turns out to be a bit challenging:
utf8_decode() is not able to process the characters.
// Fails silently (as in - nothing is output)
$str = "så";
$str = utf8_decode($str);
printf("\n%s", $str);
$str = utf8_decode($str);
printf("\n%s", $str);
iconv() fails with "Notice: iconv(): Detected an illegal character in input string".
echo iconv("UTF-8", "ISO-8859-1", "så");
Another fine and possible solution fails silently too in this scenario
$str = "så";
echo html_entity_decode(htmlentities($str, ENT_QUOTES, 'UTF-8'), ENT_QUOTES , 'ISO-8859-15');
mb_convert_encoding() silently: #
$str = "så";
echo mb_convert_encoding($str, 'ISO-8859-15', 'UTF-8');
// (No output)
Trying to fix the encoding in MySQL by converting the MySQL database characterset and collation to UTF-8 was unsuccessfully:
ALTER DATABASE myDatabase CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE myTable CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
I see a couple of ways to resolve this issue.
The first is to make a backup with correct encoding (the encoding needs to match the actual database and table encoding). You can verify the encoding by simply opening the resulting SQL file in a text editor.
The other is to replace double-UTF8-encoded characters with single-UTF8-encoded characters. This can be done manually in a text editor. To assist in this process, you can manually pick incorrect characters from Try UTF-8 Encoding Debugging Chart (it may be a matter of replacing 5-10 errors).
Finally, a script can assist in the process:
$str = "så";
// The two arrays can also be generated by double-encoding values in the first array and single-encoding values in the second array.
$str = str_replace(["Ã","Â¥"], ["Ã","¥"], $str);
$str = utf8_decode($str);
echo $str;
// Output: "så" (correct)
This appears to be my "preferred" solution:
<form action="www.spufalcons.com/index.aspx?tab=gymnastics&path=gym" method="post"> <div>
<input type="submit" value="Gymnastics"></div>
Sorry for the presentation format - I'm still trying to learn how to use this forum....
I do have a follow-up question. In looking at my MySQL database of URL's it appears that ~30% of the URL's will need to use this post/div wrapper approach. This leaves ~70% that cannot accept the "post" attribute. For example:
<form action="http://www.google.com" method="post">
<div>
<input type="submit" value="Google"/>
</div></form>
does not work. Do you have a recommendation for how to best handle this get/post condition test. Off the top of my head I'm guessing that using PHP to evaluate the existence of the "?" character in the URL may be my best approach, although I'm not sure how to structure the HTML form to accomplish this.
Thank YOU!
You can add the port in below methods.
Run -> Configurations section
In application.xml
add server.port=XXXX
Just apply the style attribute to the tr tag. In the case of multiple tr tags, you will have to apply the style to each element, or wrap them in a tbody tag:
<table>
<tr><th>Test Table</th><tr>
<tbody style="display:none">
<tr><td>123456789</td><tr>
<tr><td>123456789</td><tr>
<tr><td>123456789</td><tr>
</tbody>
</table>
In C, the order that you define things often matters. Either move the definition of outchar to the top, or provide a prototype at the top, like this:
#include <stdio.h> #include <stdlib.h> void outchar(char ch); int main() { outchar('A'); outchar('B'); outchar('C'); return 0; } void outchar(char ch) { printf("%c", ch); }
Also, you should be specifying the return type of every function. I added that for you.
This article covers various ways of concatenating strings in SQL, including an improved version of your code which doesn't XML-encode the concatenated values.
SELECT ID, abc = STUFF
(
(
SELECT ',' + name
FROM temp1 As T2
-- You only want to combine rows for a single ID here:
WHERE T2.ID = T1.ID
ORDER BY name
FOR XML PATH (''), TYPE
).value('.', 'varchar(max)')
, 1, 1, '')
FROM temp1 As T1
GROUP BY id
To understand what's happening, start with the inner query:
SELECT ',' + name
FROM temp1 As T2
WHERE T2.ID = 42 -- Pick a random ID from the table
ORDER BY name
FOR XML PATH (''), TYPE
Because you're specifying FOR XML
, you'll get a single row containing an XML fragment representing all of the rows.
Because you haven't specified a column alias for the first column, each row would be wrapped in an XML element with the name specified in brackets after the FOR XML PATH
. For example, if you had FOR XML PATH ('X')
, you'd get an XML document that looked like:
<X>,aaa</X>
<X>,bbb</X>
...
But, since you haven't specified an element name, you just get a list of values:
,aaa,bbb,...
The .value('.', 'varchar(max)')
simply retrieves the value from the resulting XML fragment, without XML-encoding any "special" characters. You now have a string that looks like:
',aaa,bbb,...'
The STUFF
function then removes the leading comma, giving you a final result that looks like:
'aaa,bbb,...'
It looks quite confusing at first glance, but it does tend to perform quite well compared to some of the other options.
id is not a good selector now. You can define some properties on the rows. And you can use them as selector.
<tr category="petshop" type="fish"><td>little fish</td></tr>
<tr category="petshop" type="dog"><td>little dog</td></tr>
<tr category="toys" type="lego"><td>lego starwars</td></tr>
and you can use a func to select the row like this (ES6):
const rowRemover = (category,type)=>{
$(`tr[category=${category}][type=${type}]`).remove();
}
rowRemover('petshop','fish');
Maybe it's too late, but in version 2.1 of TypeScript you can use key of
like this:
interface Person {
name: string;
age: number;
location: string;
}
type K1 = keyof Person; // "name" | "age" | "location"
type K2 = keyof Person[]; // "length" | "push" | "pop" | "concat" | ...
type K3 = keyof { [x: string]: Person }; // string
There's no built-in command for that because it's illegal. You can't modify the size of an array once declared.
What you're looking for is either std::vector
to simulate a dynamic array, or better yet a std::string
.
std::string first ("The dog jumps ");
std::string second ("over the log");
std::cout << first + second << std::endl;
By definition "A Set is a collection of values, where each value may occur only once." So, if your array has repeated values then only one value among the repeated values will be added to your Set.
var arr = [1, 2, 3];
var set = new Set(arr);
console.log(set); // {1,2,3}
var arr = [1, 2, 1];
var set = new Set(arr);
console.log(set); // {1,2}
So, do not convert to set if you have repeated values in your array.
You need to modify the config-db.php
and set your password to the password you gave to the user root
, or else if he has no password leave as this ''
.
Disabled Select
in angular 9.
one thing keep in mind disabled work with boolean
values
in this example, I am using the (change)
event with the select
option if the country is not selected region will be disabled.
find.component.ts file

isCountrySelected:boolean;
constructor() { }
//onchange event disabled false
onChangeCountry(id:number){
this.isCountrySelected = false;
}
ngOnInit(): void {
//initially disabled true
this.isCountrySelected = true;
}
}
find.component.html
//Country select option
<select class="form-control" (change)="onChangeCountry()" value="Choose Country">

Basically an XSD file defines how the XML file is going to look like. It's a Schema file which defines the structure of the XML file. So it specifies what the possible fields are and what size they are going to be.
An XML file is an instance of XSD as it uses the rules defined in the XSD.

Selection of Al and Ah is from AX not from EAX
e.g
EAX=0000 0000 0000 0000 0000 0000 0000 0111
So if we call AX it should return
0000 0000 0000 0111
if we call AH it should return
0000 0000
and when we call AL it should return
0000 0111
Example number 2
EAX: 22 33 55 77
AX: 55 77
AH: 55
AL: 77
example 3
EAX: 1111 0000 0000 0000 0000 0000 0000 0111
AX= 0000 0000 0000 0111
AH= 0000 0000
AL= 0000 0111
The case statements and the default statement can occur in any order in the switch statement. The default clause is an optional clause that is matched if none of the constants in the case statements can be matched.
Good Example :-
switch(5) {
case 1:
echo "1";
break;
case 2:
default:
echo "2, default";
break;
case 3;
echo "3";
break;
}
Outputs '2,default'
very useful if you want your cases to be presented in a logical order in the code (as in, not saying case 1, case 3, case 2/default) and your cases are very long so you do not want to repeat the entire case code at the bottom for the default
This simple steps worked for me, I debug on my Nexus 5 and 5X devices on Windows 8.1.
The steps to follow are these:
1) Enable from Developers Options the Debug USB Mode
2) Unplug the device from the computer
3.1) Go to Settings
? Storage
, in the ActionBar, click the option menu and choose USB computer connection
.
3.2) If you didn't find the 3.1)
option then go to Settings
? Developers Options
? Select USB Configuration
.
4) Select Camera (PTP)
connection.
5) Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection, or something like that.
6) If it doesn't work try to toggle the Debug USB Mode in the Developers Options Finally, you should see it now in the DDMS and voilà.
With Linq
var ascendingOrder = li.OrderBy(i => i);
var descendingOrder = li.OrderByDescending(i => i);
Without Linq
li.Sort((a, b) => a.CompareTo(b)); // ascending sort
li.Sort((a, b) => b.CompareTo(a)); // descending sort
Note that without Linq, the list itself is being sorted. With Linq, you're getting an ordered enumerable of the list but the list itself hasn't changed. If you want to mutate the list, you would change the Linq methods to something like
li = li.OrderBy(i => i).ToList();

A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.
A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.
By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!
If only the incoming stream stalls for more than a millisecond you are running into a timeout.
This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.
change it to:
$(function () {
var specialElementHandlers = {
'#editor': function (element,renderer) {
return true;
}
};
$('#cmd').click(function () {
var doc = new jsPDF();
doc.fromHTML(
$('#target').html(), 15, 15,
{ 'width': 170, 'elementHandlers': specialElementHandlers },
function(){ doc.save('sample-file.pdf'); }
);
});
});
and it will work.
get()
returned more than one topic -- it returned 2!
The above error indicatess that you have more than one record in the DB related to the specific parameter you passed while querying using get()
such as
Model.objects.get(field_name=some_param)
To avoid this kind of error in the future, you always need to do query as per your schema design. In your case you designed a table with a many-to-many relationship so obviously there will be multiple records for that field and that is the reason you are getting the above error.
So instead of using get()
you should use filter()
which will return multiple records. Such as
Model.objects.filter(field_name=some_param)
Please read about how to make queries in django here.

The model has a save
method, which saves all the details necessary to reconstitute the model. An example from the keras documentation:
from keras.models import load_model
model.save('my_model.h5') # creates a HDF5 file 'my_model.h5'
del model # deletes the existing model
# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')
Only static functions are called with class name.
classname::Staicfunction();
Non static functions have to be called using objects.
classname obj;
obj.Somefunction();
This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.
You can reverse the logic. Instead of deleting an invalid row after it has been inserted, write an INSTEAD OF
trigger to insert only if you verify the row is valid.
CREATE TRIGGER mytrigger ON sometable
INSTEAD OF INSERT
AS BEGIN
DECLARE @isnum TINYINT;
SELECT @isnum = ISNUMERIC(somefield) FROM inserted;
IF (@isnum = 1)
INSERT INTO sometable SELECT * FROM inserted;
ELSE
RAISERROR('somefield must be numeric', 16, 1)
WITH SETERROR;
END
If your application doesn't want to handle errors (as Joel says is the case in his app), then don't RAISERROR
. Just make the trigger silently not do an insert that isn't valid.
I ran this on SQL Server Express 2005 and it works. Note that INSTEAD OF
triggers do not cause recursion if you insert into the same table for which the trigger is defined.
I was looking for the same thing and I just found this list
Revised Answer
If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:
var myname varchar2(20);
exec :myname := 'Tom';
SELECT *
FROM Customers
WHERE Name = :myname;
In many tools (such as Toad and SQL Developer), omitting the var
and exec
statements will cause the program to prompt you for the value.
Original Answer
A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT
(roughly equivalent to print
) to output the variable:
DECLARE
myname varchar2(20);
BEGIN
myname := 'Tom';
dbms_output.print_line(myname);
END;
This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:
CREATE FUNCTION my_function (myname in varchar2)
my_refcursor out sys_refcursor
BEGIN
open my_refcursor for
SELECT *
FROM Customers
WHERE Name = myname;
return my_refcursor;
END my_function;
A function is not even needed. Just put parentheses around the default expression:
create temporary table test(
id int,
ts timestamp without time zone default (now() at time zone 'utc')
);
You can find out what Git does with a file by seeing what it does when you add it to the index. The index is like a pre-commit. With the index committed, you can use git checkout
to bring everything that was in the index back into the working directory. So, what does Git do when you add a symbolic link to the index?
To find out, first, make a symbolic link:
$ ln -s /path/referenced/by/symlink symlink
Git doesn't know about this file yet. git ls-files
lets you inspect your index (-s
prints stat
-like output):
$ git ls-files -s ./symlink
[nothing]
Now, add the contents of the symbolic link to the Git object store by adding it to the index. When you add a file to the index, Git stores its contents in the Git object store.
$ git add ./symlink
So, what was added?
$ git ls-files -s ./symlink
120000 1596f9db1b9610f238b78dd168ae33faa2dec15c 0 symlink
The hash is a reference to the packed object that was created in the Git object store. You can examine this object if you look in .git/objects/15/96f9db1b9610f238b78dd168ae33faa2dec15c
in the root of your repository. This is the file that Git stores in the repository, that you can later check out. If you examine this file, you'll see it is very small. It does not store the contents of the linked file. To confirm this, print the contents of the packed repository object with git cat-file
:
$ git cat-file -p 1596f9db1b9610f238b78dd168ae33faa2dec15c
/path/referenced/by/symlink
(Note 120000
is the mode listed in ls-files
output. It would be something like 100644
for a regular file.)
But what does Git do with this object when you check it out from the repository and into your filesystem? It depends on the core.symlinks
config. From man git-config
:
core.symlinks
If false, symbolic links are checked out as small plain files that contain the link text.
So, with a symbolic link in the repository, upon checkout you either get a text file with a reference to a full filesystem path, or a proper symbolic link, depending on the value of the core.symlinks
config.
Either way, the data referenced by the symlink is not stored in the repository.
A simple function like below will help :
public string GetCurrentPageName()
{
string sPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath);
string sRet = oInfo.Name;
return sRet;
}
create_function
did not work for me inside a class. I had to use call_user_func
.
<?php
class Dispatcher {
//Added explicit callback declaration.
var $callback;
public function Dispatcher( $callback ){
$this->callback = $callback;
}
public function asynchronous_method(){
//do asynch stuff, like fwrite...then, fire callback.
if ( isset( $this->callback ) ) {
if (function_exists( $this->callback )) call_user_func( $this->callback, "File done!" );
}
}
}
Then, to use:
<?php
include_once('Dispatcher.php');
$d = new Dispatcher( 'do_callback' );
$d->asynchronous_method();
function do_callback( $data ){
print 'Data is: ' . $data . "\n";
}
?>
[Edit] Added a missing parenthesis. Also, added the callback declaration, I prefer it that way.
A rewrite of the answer by Sarfraz would be something like this, I think:
<script>
document.getElementById('change').onclick = changeColor;
function changeColor() {
document.body.style.color = "purple";
return false;
}
</script>
You'd either have to put this script at the bottom of your page, right before the closing body tag, or put the handler assignment in a function called onload - or if you're using jQuery there's the very elegant $(document).ready(function() { ... } );
Note that when you assign event handlers this way, it takes the functionality out of your HTML. Also note you set it equal to the function name -- no (). If you did onclick = myFunc();
the function would actually execute when the handler is being set.
And I'm curious -- you knew enough to script changing the background color, but not the text color? strange:)
Yes. The windows-kill
project does exactly what you want:
windows-kill -SIGINT 1234
I know this is old, but here's the solution I came up with when I didn't like the ones I found.
-Loop through the array (Variant) adding each element and some divider to a string, unless it matches the one you want to remove -Then split the string on the divider
tmpString=""
For Each arrElem in GlobalArray
If CStr(arrElem) = "removeThis" Then
GoTo SkipElem
Else
tmpString =tmpString & ":-:" & CStr(arrElem)
End If
SkipElem:
Next
GlobalArray = Split(tmpString, ":-:")
Obviously the use of strings creates some limitations, like needing to be sure of the information already in the array, and as-is this code makes the first array element blank, but it does what I need and with a little more work it could be more versatile.
You can also add underscore.js to your project and will be able to do it in one line:
_.map($("input[name='category_ids[]']:checked"), function(el){return $(el).val()})
You can also do what the "Service Reference" generated code does
public class ServiceXClient : ClientBase<IServiceX>, IServiceX
{
public ServiceXClient() { }
public ServiceXClient(string endpointConfigurationName) :
base(endpointConfigurationName) { }
public ServiceXClient(string endpointConfigurationName, string remoteAddress) :
base(endpointConfigurationName, remoteAddress) { }
public ServiceXClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
base(endpointConfigurationName, remoteAddress) { }
public ServiceXClient(Binding binding, EndpointAddress remoteAddress) :
base(binding, remoteAddress) { }
public bool ServiceXWork(string data, string otherParam)
{
return base.Channel.ServiceXWork(data, otherParam);
}
}
Where IServiceX is your WCF Service Contract
Then your client code:
var client = new ServiceXClient(new WSHttpBinding(SecurityMode.None), new EndpointAddress("http://localhost:911"));
client.ServiceXWork("data param", "otherParam param");
I had this same problem. For me, it was due to Cache-Control header being set at the server level in IIS to no-cache, no-store. So for my application I had to add in the below to my web.config:
<httpProtocol>
<customHeaders>
<remove name="Cache-Control" />
</customHeaders>
</httpProtocol>
Use -C
option of tar:
tar zxvf <yourfile>.tar.gz -C /usr/src/
and then, the content of the tar should be in:

When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink]
, then it should be assigned a name of the property the value of which will be the route it should navigate the user to.
So to fix your issue, replace this routerLink="['/about']"
with routerLink="/about"
in your HTML.
There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:
<nav class="main-nav>
<ul
class="main-nav__list"
ng-sticky
addClass="main-sticky-link"
[ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/">Home</a>
</li>
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/about">About us</a>
</li>
</ul>
</nav>
It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>
, either in your template provided above or in a parent component.
There's another issue with your AppRoutingModule
. You need to export the RouterModule
from there so that it is available to your AppModule
when it imports it. To fix that, export it from your AppRoutingModule
by adding it to the exports
array.
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
{ path: 'about', component: AboutComponent },
{ path: 'what', component: WhatwedoComponent },
{ path: 'contacts', component: FooterComponent },
{ path: 'projects', component: ProjectsComponent},
];
@NgModule({
imports: [
CommonModule,
RouterModule.forRoot(routes),
],
exports: [RouterModule],
declarations: []
})
export class AppRoutingModule { }
multi-disciplinary
will not be hyphenated, as explained by kennytm. But multi-\-disciplinary
has the same hyphenation opportunities that multidisciplinary
has.
I admit that I don't know why this works. It is different from the behaviour described here (emphasis mine):
The command
\-
inserts a discretionary hyphen into a word. This also becomes the only point where hyphenation is allowed in this word.
I know this is not efficient at all but is simple, intuitive and easy to read.
So if someone is looking for a not so fancy solution which can be extended to work with more values, or more specific conditions .. here is a simple code:
$result = array();
$del_value = 401;
//$del_values = array(... all the values you don`t wont);
foreach($arr as $key =>$value){
if ($value !== $del_value){
$result[$key] = $value;
}
//if(!in_array($value, $del_values)){
// $result[$key] = $value;
//}
//if($this->validete($value)){
// $result[$key] = $value;
//}
}
return $result
For example you can find any textView:
TextView textView = (TextView) ((Activity) context).findViewById(R.id.textView1);
One way of achieving this behaviour is by setting the value to _id
(which is reserved for a primary key in MongoDB) field based on the custom fields you want to treat as primary key.
i.e. If I want employee_id
as the primary key then at the time of creating document in MongoDB; assign _id
value same as that of employee_id
.
Add multiple lines : use @
string query = @"SELECT foo, bar
FROM table
WHERE id = 42";
Add String Values to the middle : use $
string text ="beer";
string query = $"SELECT foo {text} bar ";
Multiple line string Add Values to the middle: use $@
string text ="Customer";
string query = $@"SELECT foo, bar
FROM {text}Table
WHERE id = 42";
I came across this problem when building QT. The instructions I read somewhere suggested that I configure nmake using VS command prompt.
I chose the x64 command prompt and performed configure without much hassle. When i tried nmake, it gave this error.
I think some of the components were pre-built for 32-bit. The error even reported which modules were built for x86.
I used the 32 bit default VS command prompt and it worked.
As you would like to get argument (United
) for which value is given (5
) you might also consider using bidirectional map (e.g. provided by Guava: http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/BiMap.html).
$Push_Pop = $ErrorActionPreference #Suppresses errors
$ErrorActionPreference = “SilentlyContinue” #Suppresses errors
#Script
#gc .\output\*.csv -ReadCount 5 | %{$_;throw "pipeline end!"} # head
#gc .\output\*.csv | %{$num=0;}{$num++;"$num $_"} # cat -n
gc .\output\*.csv | %{$num=0;}{$num++; if($num -gt 2 -and $num -lt 7){"$num $_"}} # sed
#End Script
$ErrorActionPreference = $Push_Pop #Suppresses errors
You don't get all the errors with the pushpop code BTW, your code only works with the "sed" option. All the rest ignores anything but gc and path.
What happens if I promote the column to be a/the PK, too (a.k.a. identifying relationship)? As the column is now the PK, I must tag it with @Id (...).
This enhanced support of derived identifiers is actually part of the new stuff in JPA 2.0 (see the section 2.4.1 Primary Keys Corresponding to Derived Identities in the JPA 2.0 specification), JPA 1.0 doesn't allow Id
on a OneToOne
or ManyToOne
. With JPA 1.0, you'd have to use PrimaryKeyJoinColumn
and also define a Basic
Id
mapping for the foreign key column.
Now the question is: are @Id + @JoinColumn the same as just @PrimaryKeyJoinColumn?
You can obtain a similar result but using an Id
on OneToOne
or ManyToOne
is much simpler and is the preferred way to map derived identifiers with JPA 2.0. PrimaryKeyJoinColumn
might still be used in a JOINED inheritance strategy. Below the relevant section from the JPA 2.0 specification:
11.1.40 PrimaryKeyJoinColumn Annotation
The
PrimaryKeyJoinColumn
annotation specifies a primary key column that is used as a foreign key to join to another table.The
PrimaryKeyJoinColumn
annotation is used to join the primary table of an entity subclass in theJOINED
mapping strategy to the primary table of its superclass; it is used within aSecondaryTable
annotation to join a secondary table to a primary table; and it may be used in aOneToOne
mapping in which the primary key of the referencing entity is used as a foreign key to the referenced entity[108]....
If no
PrimaryKeyJoinColumn
annotation is specified for a subclass in the JOINED mapping strategy, the foreign key columns are assumed to have the same names as the primary key columns of the primary table of the superclass....
Example: Customer and ValuedCustomer subclass
@Entity @Table(name="CUST") @Inheritance(strategy=JOINED) @DiscriminatorValue("CUST") public class Customer { ... } @Entity @Table(name="VCUST") @DiscriminatorValue("VCUST") @PrimaryKeyJoinColumn(name="CUST_ID") public class ValuedCustomer extends Customer { ... }
[108] The derived id mechanisms described in section 2.4.1.1 are now to be preferred over
PrimaryKeyJoinColumn
for the OneToOne mapping case.
This source http://weblogs.java.net/blog/felipegaucho/archive/2009/10/24/jpa-join-table-additional-state states that using @ManyToOne and @Id works with JPA 1.x. Who's correct now?
The author is using a pre release JPA 2.0 compliant version of EclipseLink (version 2.0.0-M7 at the time of the article) to write an article about JPA 1.0(!). This article is misleading, the author is using something that is NOT part of JPA 1.0.
For the record, support of Id
on OneToOne
and ManyToOne
has been added in EclipseLink 1.1 (see this message from James Sutherland, EclipseLink comitter and main contributor of the Java Persistence wiki book). But let me insist, this is NOT part of JPA 1.0.
We have some generic playbooks that are usable by a large number of teams. We also have environment specific inventory files, that contain multiple group declarations.
To force someone calling a playbook to specify a group to run against, we seed a dummy entry at the top of the playbook:
[ansible-dummy-group]
dummy-server
We then include the following check as a first step in the shared playbook:
- hosts: all
gather_facts: False
run_once: true
tasks:
- fail:
msg: "Please specify a group to run this playbook against"
when: '"dummy-server" in ansible_play_batch'
If the dummy-server shows up in the list of hosts this playbook is scheduled to run against (ansible_play_batch), then the caller didn't specify a group and the playbook execution will fail.
What you want to do is a combination of part of 1 and all of 2.
You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.
But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.
From the javadoc:
Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.
The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.
Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:
import static org.mockito.Mockito.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
class ClassWithStatics {
public static String getString() {
return "String";
}
public static int getInt() {
return 1;
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
@Test
public void test() {
PowerMockito.mockStatic(ClassWithStatics.class);
when(ClassWithStatics.getString()).thenReturn("Hello!");
System.out.println("String: " + ClassWithStatics.getString());
System.out.println("Int: " + ClassWithStatics.getInt());
}
}
The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

install react-router-dom
then create two components one for valid users and other for invalid users.
try this on app.js
import React from 'react';
import {
BrowserRouter as Router,
Route,
Link,
Switch,
Redirect
} from 'react-router-dom';
import ValidUser from "./pages/validUser/validUser";
import InValidUser from "./pages/invalidUser/invalidUser";
const loggedin = false;
class App extends React.Component {
render() {
return (
<Router>
<div>
<Route exact path="/" render={() =>(

export default App;
I work in PHP and use a function to decode the binary data sent back from the server. I extract the information an input to a simple file.php and view the file through my server and all browser display the pdf artefact.
<?php
$data = 'dfjhdfjhdfjhdfjhjhdfjhdfjhdfjhdfdfjhdf==blah...blah...blah..'
$data = base64_decode($data);
header("Content-type: application/pdf");
header("Content-Length:" . strlen($data ));
header("Content-Disposition: inline; filename=label.pdf");
print $data;
exit(1);
?>
and for completion the string solution
$qb->andWhere('foo.field IN (:string)');
$qb->setParameter('string', array('foo', 'bar'), \Doctrine\DBAL\Connection::PARAM_STR_ARRAY);
I like the top voted answer; however, it has problems with list as shown.
>> a, b = ([0]*5,)*2
>> print b
[0, 0, 0, 0, 0]
>> a[0] = 1
>> print b
[1, 0, 0, 0, 0]
This is discussed in great details (here), but the gist is that a
and b
are the same object with a is b
returning True
(same for id(a) == id(b)
). Therefore if you change an index, you are changing the index of both a
and b
, since they are linked. To solve this you can do (source)
>> a, b = ([0]*5 for i in range(2))
>> print b
[0, 0, 0, 0, 0]
>> a[0] = 1
>> print b
[0, 0, 0, 0, 0]
This can then be used as a variant of the top answer, which has the "desired" intuitive results
>> a, b, c, d, e, g, h, i = (True for i in range(9))
>> f = (False for i in range(1)) #to be pedantic
You shouldn't overload the templates with complex logic, it's a bad practice. Remember to always keep it simple!
The better approach would be to extract this logic into reusable function on your $rootScope
:
.run(function ($rootScope) {
$rootScope.inArray = function (item, array) {
return (-1 !== array.indexOf(item));
};
})
Then, use it in your template:
<li ng-class="{approved: inArray(jobSet, selectedForApproval)}"></li>
I think everyone will agree that this example is much more readable and maintainable.
This topic is old but if other people like me search a solution, this is a solution that I have found:
Public Function DBStats() As Boolean
On Error GoTo errorHandler
If Not IsNull(myBase.Version) Then
DBStats = True
End If
Exit Function
errorHandler:
DBStats = False
End Function
So "myBase" is a Database Object, I have made a class to access to database (class with insert, update etc...) and on the module the class is use declare in an object (obviously) and I can test the connection with "[the Object].DBStats":
Dim BaseAccess As New myClass
BaseAccess.DBOpen 'I open connection
Debug.Print BaseAccess.DBStats ' I test and that tell me true
BaseAccess.DBClose ' I close the connection
Debug.Print BaseAccess.DBStats ' I test and tell me false
Edit : In DBOpen I use "OpenDatabase" and in DBClose I use ".Close" and "set myBase = nothing" Edit 2: In the function, if you are not connect, .version give you an error so if aren't connect, the errorHandler give you false
It is really easy to achieve since the Support Library v24.2.0.
What you need to do is just:
Add the design library to your dependecies
dependencies {
compile "com.android.support:design:24.2.0"
}
Use TextInputEditText
in conjunction with TextInputLayout
<android.support.design.widget.TextInputLayout
android:id="@+id/etPasswordLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:layout_marginBottom="@dimen/login_spacing_bottom">
<android.support.design.widget.TextInputEditText
android:id="@+id/etPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/fragment_login_password_hint"
android:inputType="textPassword"/>
</android.support.design.widget.TextInputLayout>
The passwordToggleEnabled
attribute will do the job!
In your root layout don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto"
You can customize your password toggle by using:
app:passwordToggleDrawable
- Drawable to use as the password input visibility toggle icon.
app:passwordToggleTint
- Icon to use for the password input visibility toggle.
app:passwordToggleTintMode
- Blending mode used to apply the background tint.
More details in TextInputLayout documentation.
For AndroidX
Replace android.support.design.widget.TextInputLayout
with com.google.android.material.textfield.TextInputLayout
Replace android.support.design.widget.TextInputEditText
with com.google.android.material.textfield.TextInputEditText
The method you are looking for is Series.combine. However, it seems some care has to be taken around datatypes. In your example, you would (as I did when testing the answer) naively call
df['col_3'] = df.col_1.combine(df.col_2, func=get_sublist)
However, this throws the error:
ValueError: setting an array element with a sequence.
My best guess is that it seems to expect the result to be of the same type as the series calling the method (df.col_1 here). However, the following works:
df['col_3'] = df.col_1.astype(object).combine(df.col_2, func=get_sublist)
df
ID col_1 col_2 col_3
0 1 0 1 [a, b]
1 2 2 4 [c, d, e]
2 3 3 5 [d, e, f]
For max value, we can write sql query as
select age from table_name order by age desc limit 1
same way we can write in mongodb too.
db.getCollection('collection_name').find().sort({"age" : -1}).limit(1); //max age
db.getCollection('collection_name').find().sort({"age" : 1}).limit(1); //min age
In my case I resolved this issue by
login
and password
)My environment was Jenkins installed in the Windows. The UI question was why the warning was placed before the tool to resolve it.
You can center a button
without using text-align
on the parent div
by simple using margin:auto; display:block;
For example:
HTML
<div>
<button>Submit</button>
</div>
CSS
button {
margin:auto;
display:block;
}

The insert or replace query would insert a new record if id=1 does not already exist.
The update query would only oudate id=1 if it aready exist, it would not create a new record if it didn't exist.
This is an old post, but to save people some time if you get here now like I did, I suggest you have a look at the CodeHollow.FeedReader package which supports a wider range of RSS versions, is easier to use and seems more robust. https://github.com/codehollow/FeedReader
Assuming you don't want to create another class, you can always let the deserializer give you a dictionary of key-value-pairs, like so:
string s = //{ "user" : { "id" : 12345, "screen_name" : "twitpicuser"}};
var serializer = new JavaScriptSerializer();
var result = serializer.DeserializeObject(s);
You'll get back something, where you can do:
var userId = int.Parse(result["user"]["id"]); // or (int)result["user"]["id"] depending on how the JSON is serialized.
// etc.
Look at result
in the debugger to see, what's in there.
notificationManager.notify(0, notification);
Put this code instead of 0
new Random().nextInt()
Like below it works for me
notificationManager.notify(new Random().nextInt(), notification);
public ActionResult Index()
{
List<CustomerOrder_Result> obj = new List<CustomerOrder_Result>();
var orderlist = (from a in db.OrderMasters
join b in db.Customers on a.CustomerId equals b.Id
join c in db.CustomerAddresses on b.Id equals c.CustomerId
where a.Status == "Pending"
select new
{
Customername = b.Customername,
Phone = b.Phone,
OrderId = a.OrderId,
OrderDate = a.OrderDate,
NoOfItems = a.NoOfItems,
Order_amt = a.Order_amt,
dis_amt = a.Dis_amt,
net_amt = a.Net_amt,
status=a.Status,
address = c.address,
City = c.City,
State = c.State,
Pin = c.Pin
}) ;
foreach (var item in orderlist)
{
CustomerOrder_Result clr = new CustomerOrder_Result();
clr.Customername=item.Customername;
clr.Phone = item.Phone;
clr.OrderId = item.OrderId;
clr.OrderDate = item.OrderDate;
clr.NoOfItems = item.NoOfItems;
clr.Order_amt = item.Order_amt;
clr.net_amt = item.net_amt;
clr.address = item.address;
clr.City = item.City;
clr.State = item.State;
clr.Pin = item.Pin;
clr.status = item.status;
obj.Add(clr);
}
That's because you're using a non-blocking
socket and the output buffer is full.
From the send()
man page
When the message does not fit into the send buffer of the socket,
send() normally blocks, unless the socket has been placed in non-block-
ing I/O mode. In non-blocking mode it would return EAGAIN in this
case.
EAGAIN is the error code tied to "Resource temporarily unavailable"
Consider using select()
to get a better control of this behaviours
You can try with this, it worked for me
WebView wb_previewSurvey=new WebView(this);
wb_previewSurvey.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
//Required functionality here
return super.onJsAlert(view, url, message, result);
}
});
This is the favicon and is explained in the link.
e.g. from W3C
<link rel="icon"
type="image/png"
href="http://example.com/myicon.png">
Plus, of course the image file in the appropriate place.
Looks like most of the answers on this thread have not kept up. iOS Safari on iPads have fullscreen support now and it's very easy to implement using javascript.
Here's my full article on how to implement fullscreen capability on your web app.
On OSX 10.11, you can sudo nano /etc/paths
and add the path(s) you want here, one per line. Way simpler than figuring which of ~/.bashrc
, /etc/profile
, '~/.bash_profile` etc... you should add to. Besides, why export and append $PATH to itself when you can just go and modify PATH directly...?
I changed continue to continue 2 on line 1579 in shortcodeComon.php and it fixed my problem
if(trim($custom_link[$i]) == ""){
continue;
}
Change to:
if(trim($custom_link[$i]) == ""){
continue 2;
}
As others have said, it will only work when T is constrained to be a reference type. Without any constraints, you can compare with null, but only null - and that comparison will always be false for non-nullable value types.
Instead of calling Equals, it's better to use an IComparer<T>
- and if you have no more information, EqualityComparer<T>.Default
is a good choice:
public bool Compare<T>(T x, T y)
{
return EqualityComparer<T>.Default.Equals(x, y);
}
Aside from anything else, this avoids boxing/casting.
As an alternative to other solutions, we will construct the tiles by generating a grid of coordinates using itertools.product
. We will ignore partial tiles on the edges, only iterating through the Cartesian product between the two intervals, i.e. range(0, h-h%d, d) X range(0, w-w%d, d)
.
Given fp
: the file name to the image, d
: the tile size, opt.path
: the path to the directory containing the images, and opt.out
: is the directory where tiles will be outputted:
def tile(filename, dir_in, dir_out, d):
name, ext = os.path.splitext(filename)
img = Image.open(os.path.join(dir_in, fp))
w, h = img.size
grid = list(product(range(0, h-h%d, d), range(0, w-w%d, d)))
for i, j in grid:
box = (j, i, j+d, i+d)
out = os.path.join(dir_out, f'{name}_{i}_{j}{ext}')
img.crop(box).save(out)
According with the question the answer using java 1.7 is:
ArrayList<Element> arraylist = new ArrayList<Element>(Arrays.<Element>asList(array));
However it's better always use the interface:
List<Element> arraylist = Arrays.<Element>asList(array);
You should provide the second database information in `application/config/database.php´
Normally, you would set the default
database group, like so:
$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "database_name";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
$db['default']['swap_pre'] = "";
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
Notice that the login information and settings are provided in the array named $db['default']
.
You can then add another database in a new array - let's call it 'otherdb'.
$db['otherdb']['hostname'] = "localhost";
$db['otherdb']['username'] = "root";
$db['otherdb']['password'] = "";
$db['otherdb']['database'] = "other_database_name";
$db['otherdb']['dbdriver'] = "mysql";
$db['otherdb']['dbprefix'] = "";
$db['otherdb']['pconnect'] = TRUE;
$db['otherdb']['db_debug'] = FALSE;
$db['otherdb']['cache_on'] = FALSE;
$db['otherdb']['cachedir'] = "";
$db['otherdb']['char_set'] = "utf8";
$db['otherdb']['dbcollat'] = "utf8_general_ci";
$db['otherdb']['swap_pre'] = "";
$db['otherdb']['autoinit'] = TRUE;
$db['otherdb']['stricton'] = FALSE;
Now, to actually use the second database, you have to send the connection to another variabel that you can use in your model:
function my_model_method()
{
$otherdb = $this->load->database('otherdb', TRUE); // the TRUE paramater tells CI that you'd like to return the database object.
$query = $otherdb->select('first_name, last_name')->get('person');
var_dump($query);
}
That should do it. The documentation for connecting to multiple databases can be found here: http://codeigniter.com/user_guide/database/connecting.html
If you want to have two tables next to each other you can use: (with float
package loaded)
\begin{table}[H]
\begin{minipage}{.5\textwidth}
%first table
\end{minipage}
\begin{minipage}{.5\textwidth}
%second table
\end{minipage}
\end{table}
Each one will have own caption and number.
Another option is subfigure
package.
Pre-requisites:
sudo easy_install virtualenv
sudo pip install virtualenvwrapper
Installing virtualenv with Python2.6:
You could manually download, build and install another version of Python to /usr/local
or another location.
If it's another location other than /usr/local
, add it to your PATH.
Reload your shell to pick up the updated PATH.
From this point on, you should be able to call the following 2 python binaries from your shell python2.5
and python2.6
Create a new instance of virtualenv with python2.6
:
mkvirtualenv --python=python2.6 yournewenv
<sj:datepicker id="datepickerid" name="datepickername" displayFormat="%{formatDateJsp}" readonly="true"/>
Works for me.
converting object id to string(using toString() method) will do the job.
If the databases share server, have a login that has priveleges to both of the databases, and simply have a query run similiar to:
$query = $this->db->query("
SELECT t1.*, t2.id
FROM `database1`.`table1` AS t1, `database2`.`table2` AS t2
");
Otherwise I think you might have to run the 2 queries separately and fix the logic afterwards.
I found that using cast()
was the best solution for me:
cast(Format(amount, "Standard") AS CHAR CHARACTER SET utf8) AS Amount
There is also a convert()
function. More details on it here

Just 2 simple steps to solve your issue
First of all check AppendDataBoundItems property and make it assign false
Secondly clear all the items using property .clear()
{
ddl1.Items.Clear();
ddl1.datasource = sql1;
ddl1.DataBind();
}
If you need only one upper case and special character then this should work:
@"^(?=.{8,}$)(?=[^A-Z]*[A-Z][^A-Z]*$)\w*\W\w*$"
proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
This is another one
$("#header ul li").last().html('<li> Menu 5 </li>');
You have to use getStackTrace ()
method instead of printStackTrace()
. Here is a good example:
import java.io.*;
/**
* Simple utilities to return the stack trace of an
* exception as a String.
*/
public final class StackTraceUtil {
public static String getStackTrace(Throwable aThrowable) {
final Writer result = new StringWriter();
final PrintWriter printWriter = new PrintWriter(result);
aThrowable.printStackTrace(printWriter);
return result.toString();
}
/**
* Defines a custom format for the stack trace as String.
*/
public static String getCustomStackTrace(Throwable aThrowable) {
//add the class name and any message passed to constructor
final StringBuilder result = new StringBuilder( "BOO-BOO: " );
result.append(aThrowable.toString());
final String NEW_LINE = System.getProperty("line.separator");
result.append(NEW_LINE);
//add each element of the stack trace
for (StackTraceElement element : aThrowable.getStackTrace() ){
result.append( element );
result.append( NEW_LINE );
}
return result.toString();
}
/** Demonstrate output. */
public static void main (String... aArguments){
final Throwable throwable = new IllegalArgumentException("Blah");
System.out.println( getStackTrace(throwable) );
System.out.println( getCustomStackTrace(throwable) );
}
}
You can use the following workaround for it to work with the first parameter too:
var param1 =
HttpUtility.ParseQueryString(url.Substring(
new []{0, url.IndexOf('?')}.Max()
)).Get("param1");

The accepted answer is close... but no cigar!
Use textContent
instead of innerHTML
if you strictly want a string to be returned to you.
innerHTML
can have the side effect of giving you a node element if there's other dom elements in there. textContent
will guard against this possibility.
In my case it was the wrong dependecy for CrudRepository. My IDE added also follwing:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>1.11.2.RELEASE</version>
</dependency>
But I just needed:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>RELEASE</version>
</dependency>
I removed the first one and everything was fine.
Seems like you forgot the ["value"] or ->value
:
echo $data[0]->weather->weatherIconUrl[0]->value;

set NAME2="Travis"
py -u "CheckFile.py" %NAME1% %NAME2%
echo %ERRORLEVEL%
pause
--- yyy.py ---
import sys
import os
def names(f1,f2):
print (f1)
print (f2)
res= True
if f1 == "Travis":
res= False
return res
if __name__ == "__main__":
a = sys.argv[1]
b = sys.argv[2]
c = names(a, b)
if c:
sys.exit(1)
else:

In the book of Matt Stauffer he suggest to create an array in your config/app.php
to add the variable and then anywhere you reference to it with:
$myvariable = new Namearray(config('fileWhichContainsVariable.array.ConfigKeyVariable'))
Have try this solution? is good ?
You could check the position of the div using $(div).position()
and check if the left and top margin properties are less than 0 :
if($(div).position().left < 0 && $(div).position().top < 0){
alert("off screen");
}
Yes, It is called the for-each loop. Objects in the collectionName will be assigned one after one from the beginning of that collection, to the created object reference, 'objectName'. So in each iteration of the loop, the 'objectName' will be assigned an object from the 'collectionName' collection. The loop will terminate once when all the items(objects) of the 'collectionName' Collection have finished been assigning or simply the objects to get are over.
for (ObjectType objectName : collectionName.getObjects()){ //loop body> //You can use the 'objectName' here as needed and different objects will be //reepresented by it in each iteration. }
To kill a process by a specific keyword you could create an alias in ~/.bashrc
(linux) or ~/.bash_profile
(mac).
alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"
Cross-browser rotate for any element. Works in IE7 and IE8. In IE7 it looks like not working in JSFiddle but in my project worked also in IE7
var elementToRotate = $('#rotateMe');
var degreeOfRotation = 33;
var deg = degreeOfRotation;
var deg2radians = Math.PI * 2 / 360;
var rad = deg * deg2radians ;
var costheta = Math.cos(rad);
var sintheta = Math.sin(rad);
var m11 = costheta;
var m12 = -sintheta;
var m21 = sintheta;
var m22 = costheta;
var matrixValues = 'M11=' + m11 + ', M12='+ m12 +', M21='+ m21 +', M22='+ m22;
elementToRotate.css('-webkit-transform','rotate('+deg+'deg)')
.css('-moz-transform','rotate('+deg+'deg)')
.css('-ms-transform','rotate('+deg+'deg)')
.css('transform','rotate('+deg+'deg)')
.css('filter', 'progid:DXImageTransform.Microsoft.Matrix(sizingMethod=\'auto expand\','+matrixValues+')')
.css('-ms-filter', 'progid:DXImageTransform.Microsoft.Matrix(SizingMethod=\'auto expand\','+matrixValues+')');
Edit 13/09/13 15:00 Wrapped in a nice and easy, chainable, jquery plugin.

Do this using rs.next()
:
while (rs.next())

}
If the result set is empty, the code inside the loop won't execute.
One way, which seems reliable (though tested only in Firefox and Chrome) is to use JavaScript to listen for the animationend
(or its camelCased, and prefixed, sibling animationEnd
) event, and apply a short-lived (in the demo 0.01 second) animation to the element-type you plan to add. This, of course, is not an onCreate
event, but approximates (in compliant browsers) an onInsertion
type of event; the following is a proof-of-concept:
$(document).on('webkitAnimationEnd animationend MSAnimationEnd oanimationend', function(e){
var eTarget = e.target;
console.log(eTarget.tagName.toLowerCase() + ' added to ' + eTarget.parentNode.tagName.toLowerCase());
$(eTarget).draggable(); // or whatever other method you'd prefer
});
With the following HTML:
<div class="wrapper">
<button class="add">add a div element</button>
</div>
And (abbreviated, prefixed-versions-removed though present in the Fiddle, below) CSS:
/* vendor-prefixed alternatives removed for brevity */
@keyframes added {
0% {
color: #fff;
}
}
div {
color: #000;
/* vendor-prefixed properties removed for brevity */
animation: added 0.01s linear;
animation-iteration-count: 1;
}
Obviously the CSS can be adjusted to suit the placement of the relevant elements, as well as the selector used in the jQuery (it should really be as close to the point of insertion as possible).

Did you include "Management Tools" as a chosen option during setup?
Ensure this option is selected, and SQL Server Management Studio will be installed on the machine.
There is a much more concise way to do this. Arguments to a bash script can be brought into an array, which makes dealing with the elements much simpler. The script below will always print the last argument passed to a script.
argArray=( "$@" ) # Add all script arguments to argArray
arrayLength=${#argArray[@]} # Get the length of the array
lastArg=$((arrayLength - 1)) # Arrays are zero based, so last arg is -1
echo ${argArray[$lastArg]}
Sample output
$ ./lastarg.sh 1 2 buckle my shoe

In your pg_hba.conf file, I see some incorrect and confusing lines:
# fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32
# not recommend because of the lax permissions
host all all 192.168.0.1/32 trust
# wrong, /128 is an invalid netmask for ipv4, this line should be removed
host all all 192.168.0.1/128 trust
# this conflicts with the first line
# it says that that the password should be md5 and not plaintext
# I think the first line should be removed
host all all 192.168.0.1/32 md5
# this is fine except is it unnecessary because of the previous line
# which allows any user and any database to connect with md5 password
host chaosLRdb postgres 192.168.0.1/32 md5
# wrong, on local lines, an IP cannot be specified
# remove the 4th column
local all all 192.168.0.1/32 trust
I suspect that if you md5'd the password, this might work if you trim the lines. To get the md5 you can use perl or the following shell script:
echo -n 'chaos123' | md5sum
> d6766c33ba6cf0bb249b37151b068f10 -
So then your connect line would like something like:
my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433",
"chaosuser", "d6766c33ba6cf0bb249b37151b068f10");

FWIW, on Ubuntu 10.04.2 LTS installing the ca-certificates-java and the ca-certificates packages fixed this problem for me.
I am assuming what you are trying to achieve is to insert a line after the first few lines of of a textfile.
head -n10 file.txt >> newfile.txt
echo "your line >> newfile.txt
tail -n +10 file.txt >> newfile.txt
If you don't want to rest of the lines from the file, just skip the tail part.
Simply make a CSS media query which excludes tablets and mobile devices and put the hover in there. You don't really need jQuery or JavaScript for this.
@media screen and (min-device-width:1024px) {
your-element:hover {
/* Do whatever here */
}
}
And be sure to add this to your html head to make sure that it calculates with the actual pixels and not the resolution.
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
You can uninstall package name "com.example" from the device in which you run the app after than you run the app . This worked for me
add the following to the "floating" view

My solution is to write a static method inside the fragment:
public TheFragment setData(TheData data) {
TheFragment tf = new TheFragment();
tf.data = data;
return tf;
}
This way I am sure that all the data I need is inside the Fragment before any other possible operation which could need to work with it. Also it looks cleaner in my opinion.
The preferred method is actually:
@System.Web.Configuration.WebConfigurationManager.AppSettings["myKey"]
It also doesn't need a reference to the ConfigurationManager assembly, it's already in System.Web.

One of the disadvantages of using HTML for labels is when you need to write a localizable program (which should work in several languages). You will have issues to change just the translatable text. Or you will have to put the whole HTML code into your translations which is very awkward, I would even say absurd :)
gui_en.properties:
title.text=<html>Text color: <font color='red'>red</font></html>
gui_fr.properties:
title.text=<html>Couleur du texte: <font color='red'>rouge</font></html>
gui_ru.properties:
title.text=<html>???? ??????: <font color='red'>???????</font></html>
As Blazemonger said, #parent, .panel and .collapse have to be direct descendants. However, if You can't change Your html, You can do workaround using bootstrap events and methods with the following code:
$('#your-parent .collapse').on('show.bs.collapse', function (e) {
var actives = $('#your-parent').find('.in, .collapsing');
actives.each( function (index, element) {
$(element).collapse('hide');
})
})
If by "hex data" you mean a string of the form
s = "6a48f82d8e828ce82b82"
you can use
i = int(s, 16)
to convert it to an integer and
str(i)
to convert it to a decimal string.
I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:
Make sure ESLint is not run with the --no-inline-config
flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):
/* eslint-env browser */
This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.
There are plenty of environments, and you can declare more than one at the same time, for example, in-line:
/* eslint-env browser, node */
If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.
From their docs:
An environment defines global variables that are predefined. The available environments are:
browser
- browser global variables.node
- Node.js global variables and Node.js scoping.commonjs
- CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).shared-node-browser
- Globals common to both Node and Browser.[...]
Besides environments, you can make it ignore anything you want. If it warns you about using console.log()
but you don't want to be warned about it, just inline:
/* eslint-disable no-console */
You can see the list of all rules, including recommended rules to have for best coding practices.
If you need to support more than one format you will have to pattern match your input and parse accordingly.
final DateFormat fmt;
if (dateString.endsWith("Z")) {
fmt = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
} else {
fmt = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
}
I'd guess you're dealing with a bug in the API you're using which has quoted the Z
timezone date pattern somewhere...

Since no one mention: In C#, an array is a list. MyClass[]
and List<MyClass>
both implement IList<MyClass>
. (e.g. void Foo(IList<int> foo)
can be called like Foo(new[] { 1, 2, 3 })
or Foo(new List<int> { 1, 2, 3 })
)
So, if you are writing a method that accepts a List<MyClass>
as an argument, but uses only subset of features, you may want to declare as IList<MyClass>
instead for callers' convenience.

In your public View getView
method change return null;

If your elements are distinct, then a simple set difference will do.
c = [1,2,3,4,'x',8,6,7,'x',9,'x']
z = list(set(c) - set(['x']))
print z
[1, 2, 3, 4, 6, 7, 8, 9]
A couple of reasons that this can happen:
1) You see this error with an incorrect namespace, or a typo in the attribute. Like 'xmlns' is wrong, it should be xmlns:android
2) First node needs to contain:
xmlns:android="http://schemas.android.com/apk/res/android"
3) If you are integrating AdMob, check custom parameters like ads:adSize
, you need
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
4) If you are using LinearLayout
you might have to define tools:
xmlns:tools="http://schemas.android.com/tools"
... is syntax for variadic arguments.
I think it is implemented by the complier using slice ([]Type)
, just like the function append :
func append(slice []Type, elems ...Type) []Type
when you use "elems" in "append", actually it is a slice([]type).
So "a = append(a[:0], a[1:]...)
" means "a = append(a[0:0], a[1:])
"
a[0:0]
is a slice which has nothing
a[1:]
is "Hello2 Hello3"
This is how it works

The Value of num will be some garbage value from the main memory(RAM). its better if you initialize the variable just after creating.

What you need to do is create a Stream
out of the Map
's .entrySet()
:
// Map<K, V> --> Set<Map.Entry<K, V>> --> Stream<Map.Entry<K, V>>
map.entrySet().stream()
From the on, you can .filter()
over these entries. For instance:
// Stream<Map.Entry<K, V>> --> Stream<Map.Entry<K, V>>
.filter(entry -> entry.getKey() == 1)
And to obtain the values from it you .map()
:
// Stream<Map.Entry<K, V>> --> Stream<V>
.map(Map.Entry::getValue)
Finally, you need to collect into a List
:
// Stream<V> --> List<V>
.collect(Collectors.toList())
If you have only one entry, use this instead (NOTE: this code assumes that there is a value; otherwise, use .orElse()
; see the javadoc of Optional
for more details):
// Stream<V> --> Optional<V> --> V
.findFirst().get()

If you want to find the word you can use
var word = words.Where(item => item.IsKey).First();
This gives you the first item for which IsKey is true (if there might be non you might want to use .FirstOrDefault()
To get both the item and the index you can use
KeyValuePair<WordType, int> word = words.Select((item, index) => new KeyValuePair<WordType, int>(item, index)).Where(item => item.Key.IsKey).First();

They are JavaScript components that render special font data in JSON format (which you can convert from TrueType or OpenType formats on their web sites) via the new <canvas> element in all newer browsers except Internet Explorer and via VML in Internet Explorer.
The main problem with both (as of now) is that selecting text does not work or at least works only quite awkwardly.
Still, it is very nice for headlines. Body text... I don't know.
And it's surprisingly fast.
To write the best code, you "should" use the latter approach, with a function reference:
var refreshId = setInterval(function() {}, 5000);
or
function test() {}
var refreshId = setInterval(test, 5000);
but your approach of
function test() {}
var refreshId = setInterval("test()", 5000);
is basically valid, too (as long as test()
is global).
Note that there is no such thing really as "in jQuery". You're still writing the Javascript language; you're just using some pre-made functions that are the jQuery library.
You can try max-height: 70px; See if that works.
I'm not sure why, but I needed to use the old skool document.getElementById();
<audio id="player" src="http://audio.micronemez.com:8000/micronemez-radio.ogg"> </audio>
<a id="button" title="button">play sound</a>
and the JS:
$(document).ready(function() {
var playing = false;
$('a#button').click(function() {
$(this).toggleClass("down");
if (playing == false) {
document.getElementById('player').play();
playing = true;
$(this).text("stop sound");
} else {
document.getElementById('player').pause();
playing = false;
$(this).text("restart sound");
}
});
});

Your description is a little confusing.
Generally speaking, though some C++ implementations have mechanisms for it, you're not supposed to ask about the type. Instead, you are supposed to do a dynamic_cast on the pointer to A. What this will do is that at runtime, the actual contents of the pointer to A will be checked. If you have a B, you'll get your pointer to B. Otherwise, you'll get an exception or null.
mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/…
to get it rewritten to a corresponding /folder1/…
.
Try this:
RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1
This rule will rewrite every request that starts with the URI path /apple/…
internally to /folder1/…
.
Edit As you are actually looking for the other way round:
RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]
This rule is designed to work together with the other rule above. Requests of /folder1/…
will be redirected externally to /apple/…
and requests of /apple/…
will then be rewritten internally back to /folder1/…
.
Because I had the same problem, I want to stress that actually the first comment by Brian Cain is the solution to the "IOError: [Errno 13]"-problem:
If executed in the temp directory (cd /tmp
), the IOError does not occur anymore if I run sudo pip install foo
.

Just wondering.. is that really possible in MySQL? it will delete t1 and t2? or I just misunderstood the question.
But if you just want to delete table1 with multiple join conditions, just don't alias the table you want to delete
this:
DELETE t1,t2
FROM table1 AS t1
INNER JOIN table2 t2 ...
INNER JOIN table3 t3 ...
should be written like this to work in MSSQL:
DELETE table1
FROM table1
INNER JOIN table2 t2 ...
INNER JOIN table3 t3 ...
to contrast how the other two common RDBMS do a delete operation:

You need to add import com.fasterxml.jackson.annotation.JsonInclude;
Add
@JsonInclude(JsonInclude.Include.NON_NULL)
on top of POJO
If you have nested POJO then
@JsonInclude(JsonInclude.Include.NON_NULL)
need to add on every values.
NOTE: JAXRS (Jersey) automatically handle this scenario 2.6 and above.
You can use class System.Array for add new element:
Array.Resize(ref objArray, objArray.Length + 1);
objArray[objArray.Length - 1] = new Someobject();
str_split
can do the trick. Note that strings in PHP can be accessed just like a chars array, in most cases, you won't need to split your string into a "new" array.
Class java.sql.TimeStamp
extends from java.util.Date
.
You can directly assign a TimeStamp
object to Date
reference:
TimeStamp timeStamp = //whatever value you have;
Date startDate = timestampValue;
while(!feof(fp))
{
ch = fgetc(fp);
if(ch == '\n')
{
lines++;
}
}
But please note: Why is “while ( !feof (file) )” always wrong?.
By iterating I learned that the Token field and the token in an endpoint can be the same. So I set them to be the same as the user token and it works! Also check that the user has privileges to make a job.
Anyway, you can check access.log and see if Bitbucket makes a try or not.
P.S. Also a link to Bitbucket Documentation. May some day it will become more useful.
Not really a direct answer, but I'd highly recommend using LINQPad for this kind of "exploratory" C# programming.
I have the following as a saved "query" in LINQPad:
var p = new System.Diagnostics.Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments = "/c echo Foo && echo Bar";
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardOutput.ReadToEnd().Dump();
Feel free to adapt as needed.
A couple of answers that should work above but this is how i would write it.
Also, i wouldn't declare controllers inside templates. It's better to declare them on your routes imo.
add-text.tpl.html
<div ng-controller="myController">
<form ng-submit="addText(myText)">
<input type="text" placeholder="Let's Go" ng-model="myText">
<button type="submit">Add</button>
</form>
<ul>
<li ng-repeat="text in arrayText">{{ text }}</li>
</ul>
</div>
app.js
(function() {
function myController($scope) {
$scope.arrayText = ['hello', 'world'];
$scope.addText = function(myText) {
$scope.arrayText.push(myText);
};
}
angular.module('app', [])
.controller('myController', myController);
})();
This is what I did on windows.

Check if you have any elevation on one of the Views in XML. If so, add elevation to the other item or remove the elevation to solve the issue. From there, it's the order of the views that dictates what comes above the other.
To toggle a checkbox or you can use
element.checked = !element.checked;
so you could use
if (attribute == elementName)
{
arrChecks[i].checked = !arrChecks[i].checked;
} else {
arrChecks[i].checked = false;
}
What are iml files in Android Studio project?
A Google search on iml file
turns up:
IML is a module file created by IntelliJ IDEA, an IDE used to develop Java applications. It stores information about a development module, which may be a Java, Plugin, Android, or Maven component; saves the module paths, dependencies, and other settings.
(from this page)
why not to use gradle scripts to integrate with external modules that you add to your project.
You do "use gradle scripts to integrate with external modules", or your own modules.
However, Gradle is not IntelliJ IDEA's native project model — that is separate, held in .iml
files and the metadata in .idea/
directories. In Android Studio, that stuff is largely generated out of the Gradle build scripts, which is why you are sometimes prompted to "sync project with Gradle files" when you change files like build.gradle
. This is also why you don't bother putting .iml
files or .idea/
in version control, as their contents will be regenerated.
If I have a team that work in different IDE's like Eclipse and AS how to make project IDE agnostic?
To a large extent, you can't.
You are welcome to have an Android project that uses the Eclipse-style directory structure (e.g., resources and manifest in the project root directory). You can teach Gradle, via build.gradle
, how to find files in that structure. However, other metadata (compileSdkVersion
, dependencies, etc.) will not be nearly as easily replicated.
Other alternatives include:
Move everybody over to another build system, like Maven, that is equally integrated (or not, depending upon your perspective) to both Eclipse and Android Studio
Hope that Andmore takes off soon, so that perhaps you can have an Eclipse IDE that can build Android projects from Gradle build scripts
Have everyone use one IDE
You could also do it utilizing getTimezoneOffset and getTime,
x = new Date()_x000D_
var UTCseconds = (x.getTime() + x.getTimezoneOffset()*60*1000)/1000;_x000D_
_x000D_
console.log("UTCseconds", UTCseconds)
_x000D_
Trying to set background color based on condition:
Consider variable x with some numeric value.
<p [ngStyle]="{ backgroundColor: x > 4 ? 'lightblue' : 'transparent' }">
This is a sample Text

NestedScrollView
as the name suggests is used when there is a need for a scrolling view inside another scrolling view. Normally this would be difficult to accomplish since the system would be unable to decide which view to scroll.
This is where NestedScrollView
comes in.
Here's an example (sorry for any typos)
var itemsToRemove = new ArrayList(); // should use generic List if you can
foreach (var item in originalArrayList) {
if (...) {
itemsToRemove.Add(item);
}
}
foreach (var item in itemsToRemove) {
originalArrayList.Remove(item);
}
OR if you're using 3.5, Linq makes the first bit easier:
itemsToRemove = originalArrayList
.Where(item => ...)
.ToArray();
foreach (var item in itemsToRemove) {
originalArrayList.Remove(item);
}
Replace "..." with your condition that determines if item should be removed.
Update 2017 vibrate(interval) method is deprecated with Android-O(API 8.0)
To support all Android versions use this method.
// Vibrate for 150 milliseconds
private void shakeItBaby() {
if (Build.VERSION.SDK_INT >= 26) {
((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(VibrationEffect.createOneShot(150, VibrationEffect.DEFAULT_AMPLITUDE));
} else {
((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(150);
}
}
Kotlin:
// Vibrate for 150 milliseconds
private fun shakeItBaby(context: Context) {
if (Build.VERSION.SDK_INT >= 26) {
(context.getSystemService(VIBRATOR_SERVICE) as Vibrator).vibrate(VibrationEffect.createOneShot(150, VibrationEffect.DEFAULT_AMPLITUDE))
} else {
(context.getSystemService(VIBRATOR_SERVICE) as Vibrator).vibrate(150)
}
}
There is also an issue with pip
on 64 bit Cygwin. After installation, the output of pip
command is always empty, no matters what commands/options do you use (even pip -V
doesn't produce any output).
If it's your case, just install the development version of Cygwin's package libuuid called libuuid-devel
. Without that package using of libuuid causes a segfault. And pip
uses that package, so the segfault is the cause of an empty output of pip
on Cygwin x64. On 32 bit Cygwin it's working fine even without that package.

Update Android emulator alone from SDK tool
Another option for the same result with ConstraintSet animation:
1) Put all the animated views in one ConstraintLayout
2) Animate it from code like this (if you want some more effects its up to you..this is only example)
menuItem1 and menuItem2 is the first and second FABs in menu, descriptionItem1 and descriptionItem2 is the description to the left of menu, parentConstraintLayout is the root ConstraintLayout wich contains all the animated views, isMenuOpened is some function to change open/closed flag in the state
I put animation code in extension file but its not necessary.
fun FloatingActionButton.expandMenu(
menuItem1: View,
menuItem2: View,
descriptionItem1: TextView,
descriptionItem2: TextView,
parentConstraintLayout: ConstraintLayout,
isMenuOpened: (Boolean)-> Unit
) {
val constraintSet = ConstraintSet()
constraintSet.clone(parentConstraintLayout)
constraintSet.setVisibility(descriptionItem1.id, View.VISIBLE)
constraintSet.clear(menuItem1.id, ConstraintSet.TOP)
constraintSet.connect(menuItem1.id, ConstraintSet.BOTTOM, this.id, ConstraintSet.TOP, 0)
constraintSet.connect(menuItem1.id, ConstraintSet.START, this.id, ConstraintSet.START, 0)
constraintSet.connect(menuItem1.id, ConstraintSet.END, this.id, ConstraintSet.END, 0)
constraintSet.setVisibility(descriptionItem2.id, View.VISIBLE)
constraintSet.clear(menuItem2.id, ConstraintSet.TOP)
constraintSet.connect(menuItem2.id, ConstraintSet.BOTTOM, menuItem1.id, ConstraintSet.TOP, 0)
constraintSet.connect(menuItem2.id, ConstraintSet.START, this.id, ConstraintSet.START, 0)
constraintSet.connect(menuItem2.id, ConstraintSet.END, this.id, ConstraintSet.END, 0)
val transition = AutoTransition()
transition.duration = 150
transition.interpolator = AccelerateInterpolator()
transition.addListener(object: Transition.TransitionListener {
override fun onTransitionEnd(p0: Transition) {
isMenuOpened(true)
}
override fun onTransitionResume(p0: Transition) {}
override fun onTransitionPause(p0: Transition) {}
override fun onTransitionCancel(p0: Transition) {}
override fun onTransitionStart(p0: Transition) {}
})
TransitionManager.beginDelayedTransition(parentConstraintLayout, transition)
constraintSet.applyTo(parentConstraintLayout)
}
HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.
Only nested classes can be static. By doing so you can use the nested class without having an instance of the outer class.
class OuterClass {
public static class StaticNestedClass {
}
public class InnerClass {
}
public InnerClass getAnInnerClass() {
return new InnerClass();
}
//This method doesn't work
public static InnerClass getAnInnerClassStatically() {
return new InnerClass();
}
}
class OtherClass {
//Use of a static nested class:
private OuterClass.StaticNestedClass staticNestedClass = new OuterClass.StaticNestedClass();
//Doesn't work
private OuterClass.InnerClass innerClass = new OuterClass.InnerClass();
//Use of an inner class:
private OuterClass outerclass= new OuterClass();
private OuterClass.InnerClass innerClass2 = outerclass.getAnInnerClass();
private OuterClass.InnerClass innerClass3 = outerclass.new InnerClass();
}

Use the @RequestParam to pass a parameter to the controller handler method.
In the jsp your form should have an input field with name = "id"
like the following:
<input type="text" name="id" />
<input type="submit" />
Then in your controller, your handler method should be like the following:
@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
Person person = personService.getCurrentlyAuthenticatedUser();
model.addAttribute("person", new Person());
model.addAttribute("listPersons", this.personService.listPersons());
model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
return "note";
}

InetAddress.getLocalHost().getHostName()
is better (as explained by Nick), but still not very good
One host can be known under many different hostnames. Usually you'll be looking for the hostname your host has in a specific context.
For example, in a web application, you might be looking for the hostname used by whoever issued the request you're currently handling. How to best find that one depends on which framework you're using for your web application.
In some kind of other internet-facing service, you'll want the hostname your service is available through from the 'outside'. Due to proxies, firewalls etc this might not even be a hostname on the machine your service is installed on - you might try to come up with a reasonable default, but you should definitely make this configurable for whoever installs this.
I interpreted the question as using cast on a subquery. Yes, you can do that:
select cast((<subquery>) as <newtype>)
If you do so, then you need to be sure that the returns one row and one value. And, since it returns one value, you could put the cast in the subquery instead:
select (select cast(<val> as <newtype>) . . .)
I'd like to note that it's usually preferable to change the class of the node instead of it's style and let CSS handle what that means.
You can run your script via cmd and be in script-directory:
cmd /k cd /d $(CURRENT_DIRECTORY) && python $(FULL_CURRENT_PATH)
Here is a demo. Use position:fixed; top:0; left:0;
so the header always stay on top.
?#header {
background:red;
height:50px;
width:100%;
position:fixed;
top:0;
left:0;
}.scroller {
height:300px;
overflow:scroll;
}
Since python 3.6 you can use fstring :
>>> length = 1
>>> print(f'length = {length:03}')
length = 001
origin/xxx
branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).
What you need to do to update the remote is to force push your local changes to master:
git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master
One other option is to use a plyr function:
df <- ldply(listOfDataFrames, data.frame)
This is a little slower than the original:
> system.time({ df <- do.call("rbind", listOfDataFrames) })
user system elapsed
0.25 0.00 0.25
> system.time({ df2 <- ldply(listOfDataFrames, data.frame) })
user system elapsed
0.30 0.00 0.29
> identical(df, df2)
[1] TRUE
My guess is that using do.call("rbind", ...)
is going to be the fastest approach that you will find unless you can do something like (a) use a matrices instead of a data.frames and (b) preallocate the final matrix and assign to it rather than growing it.
Edit 1:
Based on Hadley's comment, here's the latest version of rbind.fill
from CRAN:
> system.time({ df3 <- rbind.fill(listOfDataFrames) })
user system elapsed
0.24 0.00 0.23
> identical(df, df3)
[1] TRUE
This is easier than rbind, and marginally faster (these timings hold up over multiple runs). And as far as I understand it, the version of plyr
on github is even faster than this.
The problem is that /var/www
doesn't exist either, and mkdir
isn't recursive by default -- it expects the immediate parent directory to exist.
Use:
mkdir -p /var/www/app
...or install a package that creates a /var/www
prior to reaching this point in your Dockerfile.
