This error is usually caused by the missing Visual C++ Redistributable file
, which is a required dependency for most of the application on Windows Computer.
Download Visual C++ Redistributable from here and install it. After installing this, Reboot the system.
You can do this conversion with the OpenSSL library
Windows binaries can be found here:

I had an issue with the downscaleImage()
function posted above by @daniel-allen-langdon in that the image.width
and image.height
properties are not available immediately because the image load is asynchronous.
Please see updated TypeScript example below that takes this into account, uses async
functions, and resizes the image based on the longest dimension rather than just the width
function getImage(dataUrl: string): Promise<HTMLImageElement>
{
return new Promise((resolve, reject) => {
const image = new Image();
image.src = dataUrl;
image.onload = () => {
resolve(image);
};
image.onerror = (el: any, err: ErrorEvent) => {
reject(err.error);
};
});
}
export async function downscaleImage(
dataUrl: string,
imageType: string, // e.g. 'image/jpeg'
resolution: number, // max width/height in pixels
quality: number // e.g. 0.9 = 90% quality
): Promise<string> {
// Create a temporary image so that we can compute the height of the image.
const image = await getImage(dataUrl);
const oldWidth = image.naturalWidth;
const oldHeight = image.naturalHeight;
console.log('dims', oldWidth, oldHeight);
const longestDimension = oldWidth > oldHeight ? 'width' : 'height';
const currentRes = longestDimension == 'width' ? oldWidth : oldHeight;
console.log('longest dim', longestDimension, currentRes);
if (currentRes > resolution) {
console.log('need to resize...');
// Calculate new dimensions
const newSize = longestDimension == 'width'
? Math.floor(oldHeight / oldWidth * resolution)
: Math.floor(oldWidth / oldHeight * resolution);
const newWidth = longestDimension == 'width' ? resolution : newSize;
const newHeight = longestDimension == 'height' ? resolution : newSize;
console.log('new width / height', newWidth, newHeight);
// Create a temporary canvas to draw the downscaled image on.
const canvas = document.createElement('canvas');
canvas.width = newWidth;
canvas.height = newHeight;
// Draw the downscaled image on the canvas and return the new data URL.
const ctx = canvas.getContext('2d')!;
ctx.drawImage(image, 0, 0, newWidth, newHeight);
const newDataUrl = canvas.toDataURL(imageType, quality);
return newDataUrl;
}
else {
return dataUrl;
}
}
This error is pretty verbose:
ValueError: could not convert string to float: id
Somewhere in your text file, a line has the word id
in it, which can't really be converted to a number.
Your test code works because the word id
isn't present in line 2
.
If you want to catch that line, try this code. I cleaned your code up a tad:
#!/usr/bin/python
import os, sys
from scipy import stats
import numpy as np
for index, line in enumerate(open('data2.txt', 'r').readlines()):
w = line.split(' ')
l1 = w[1:8]
l2 = w[8:15]
try:
list1 = map(float, l1)
list2 = map(float, l2)
except ValueError:
print 'Line {i} is corrupt!'.format(i = index)'
break
result = stats.ttest_ind(list1, list2)
print result[1]

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?
Basically, you use the /B

If you use SonarScanner CLI with Docker, you may have this error because the SonarScanner container can not access to the Sonar UI container.
Note that you will have the same error with a simple curl from another container:
docker run --rm byrnedo/alpine-curl 127.0.0.1:9000
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0
curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused
The solution is to connect the SonarScanner container to the same docker network of your sonar instance, for instance with --network=host
:
docker run --network=host -e SONAR_HOST_URL='http://127.0.0.1:9000' --user="$(id -u):$(id -g)" -v "$PWD:/usr/src" sonarsource/sonar-scanner-cli
(other parameters of this command comes from the SonarScanner CLI documentation)
I opted to write this instead to manually remove the remainder with strings so I don't have to deal with the math issues that come with numbers:
num = num.toString(); //If it's not already a String
num = num.slice(0, (num.indexOf("."))+3); //With 3 exposing the hundredths place
Number(num); //If you need it back as a Number
This will give you "15.77" with num = 15.7784514;
From an answer of @NimChimpsky in similar question:
Resource resource = new ClassPathResource("storedProcedures.sql");
InputStream resourceInputStream = resource.getInputStream();
Using ClassPathResource and interface Resource. And make sure you are adding the resources directory correctly (adding /src/main/resources/
into the classpath).
Note that Resource have a method to get a java.io.File
so you can also use:
Resource resource = new ClassPathResource("storedProcedures.sql");
FileReader fr = new FileReader(resource.getFile());
The solution work on my cases and cross-browser:
var getKeys = function(obj) {
var type = typeof obj;
var isObjectType = type === 'function' || type === 'object' || !!obj;
// 1
if(isObjectType) {
return Object.keys(obj);
}
// 2
var keys = [];
for(var i in obj) {
if(obj.hasOwnProperty(i)) {
keys.push(i)
}
}
if(keys.length) {
return keys;
}
// 3 - bug for ie9 <
var hasEnumbug = !{toString: null}.propertyIsEnumerable('toString');
if(hasEnumbug) {
var nonEnumerableProps = ['valueOf', 'isPrototypeOf', 'toString',
'propertyIsEnumerable', 'hasOwnProperty', 'toLocaleString'];
var nonEnumIdx = nonEnumerableProps.length;
while (nonEnumIdx--) {
var prop = nonEnumerableProps[nonEnumIdx];
if (Object.prototype.hasOwnProperty.call(obj, prop)) {
keys.push(prop);
}
}
}
return keys;
};
You're almost there. Simply use:
//form[@id='myform']//input[@type='submit']
The //
shortcut can also be used inside an expression.
Even though is not the fastest choice, if performance is not an issue you can use:
sum(~np.isnan(data))
.
In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop
In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop
In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop
Less obvious but more than 2 times faster :
// 10000000 runs
DateTime d = DateTime.Now;
// 484,375ms
d = new DateTime((d.Ticks / TimeSpan.TicksPerSecond) * TimeSpan.TicksPerSecond);
// 1296,875ms
d = d.AddMilliseconds(-d.Millisecond);
the accepted answer does not work (e.g. distance between 0,0 and (-10,2,10,2) should be 2).
here's code that works:
def dist2line2(x,y,line):
x1,y1,x2,y2=line
vx = x1 - x
vy = y1 - y
ux = x2-x1
uy = y2-y1
length = ux * ux + uy * uy
det = (-vx * ux) + (-vy * uy) #//if this is < 0 or > length then its outside the line segment
if det < 0:
return (x1 - x)**2 + (y1 - y)**2
if det > length:
return (x2 - x)**2 + (y2 - y)**2
det = ux * vy - uy * vx
return det**2 / length
def dist2line(x,y,line): return math.sqrt(dist2line2(x,y,line))
Replace return super.onCreateOptionsMenu(menu); with return true; in your onCreateOptionsMenu method This will help
And you should also have the onCreate method in your activity

You need to use to_timestamp()
to convert your string to a proper timestamp
value:
to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
If your column is of type DATE
(which also supports seconds), you need to use to_date()
to_date('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
To get this into a where
condition use the following:
select *
from TableA
where startdate >= to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
and startdate <= to_timestamp('12-01-2012 21:25:33', 'dd-mm-yyyy hh24:mi:ss')
You never need to use to_timestamp()
on a column that is of type timestamp
.
Using foreach would be shorter code, but probably do exactly the same steps at runtime after JIT optimization recognizes the comparison to Length in the for-loop controlling expression.
I was solving this algorithm and get stuck with the pairs part.
This explanation help me a lot https://betterexplained.com/articles/techniques-for-adding-the-numbers-1-to-100/
So to calculate the sum of series of numbers:
n(n+1)/2
But you need to calculate this
1 + 2 + ... + (n-1)
So in order to get this you can use
n(n+1)/2 - n
that is equal to
n(n-1)/2

I have two apps 1)PageViewControllerExample and 2)DelegateExample. Now i want to open DelegateExample app with PageViewControllerExample app. When i click open button in PageViewControllerExample, DelegateExample app will be opened.
For this we need to make some changes in .plist files for both the apps.
Step 1
In DelegateExample app open .plist file and add URL Types and URL Schemes. Here we need to add our required name like "myapp".
Step 2
In PageViewControllerExample app open .plist file and add this code
<key>LSApplicationQueriesSchemes</key>
<array>
<string>myapp</string>
</array>
Now we can open DelegateExample app when we click button in PageViewControllerExample.
//In PageViewControllerExample create IBAction
@IBAction func openapp(_ sender: UIButton) {
let customURL = URL(string: "myapp://")
if UIApplication.shared.canOpenURL(customURL!) {
//let systemVersion = UIDevice.current.systemVersion//Get OS version
//if Double(systemVersion)! >= 10.0 {//10 or above versions
//print(systemVersion)
//UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
//} else {
//UIApplication.shared.openURL(customURL!)
//}
//OR
if #available(iOS 10.0, *) {
UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
} else {
UIApplication.shared.openURL(customURL!)
}
} else {
//Print alert here
}

It should be possible changing setting the JAVA_HOME environment variable differently for specific applications.
When starting from the command line or from a batch script you can use set JAVA_HOME=C:\...\j2dskXXX
to change the JAVA_HOME environment.
It is possible that you also need to change the PATH
environment variable to use the correct java binary. To do this you can use set PATH=%JAVA_HOME%\bin;%PATH%
.
In some cases the whole need for declaring a variable can be avoided by using With
statement.
For example,
Dim fd As Office.FileDialog
Set fd = Application.FileDialog(msoFileDialogSaveAs)
If fd.Show Then
'use fd.SelectedItems(1)
End If
this can be rewritten as
With Application.FileDialog(msoFileDialogSaveAs)
If .Show Then
'use .SelectedItems(1)
End If
End With
You can use usort function to create own sorting rules
Please modify your index.php as follows:
require_once($yii);
$app = Yii::createWebApplication($config);
Yii::app()->setTimeZone('UTC');
$app->run();
You should quote your array keys:
$department = mysql_real_escape_string($_POST['department']);
$name = mysql_real_escape_string($_POST['name']);
$email = mysql_real_escape_string($_POST['email']);
$message = mysql_real_escape_string($_POST['message']);
As is, it was looking for constants called department
, name
, email
, message
, etc. When it doesn't find such a constant, PHP (bizarrely) interprets it as a string ('department', etc). Obviously, this can easily break if you do defined such a constant later (though it's bad style to have lower-case constants).
There are some equivalents of constructors for when the zero values can't make sensible default values or for when some parameter is necessary for the struct initialization.
Supposing you have a struct like this :
type Thing struct {
Name string
Num int
}
then, if the zero values aren't fitting, you would typically construct an instance with a NewThing
function returning a pointer :
func NewThing(someParameter string) *Thing {
p := new(Thing)
p.Name = someParameter
p.Num = 33 // <- a very sensible default value
return p
}
When your struct is simple enough, you can use this condensed construct :
func NewThing(someParameter string) *Thing {
return &Thing{someParameter, 33}
}
If you don't want to return a pointer, then a practice is to call the function makeThing
instead of NewThing
:
func makeThing(name string) Thing {
return Thing{name, 33}
}

Before doing anything else, confirm if your backup is Full or Differential. If you're trying to create a new database out of a differential backup, no matter what you do you will encounter the error.
Use a CipherOutputStream
or CipherInputStream
with a Cipher
and your FileInputStream
/ FileOutputStream
.
I would suggest something like Cipher.getInstance("AES/CBC/PKCS5Padding")
for creating the Cipher
class. CBC mode is secure and does not have the vulnerabilities of ECB mode for non-random plaintexts. It should be present in any generic cryptographic library, ensuring high compatibility.
Don't forget to use a Initialization Vector (IV) generated by a secure random generator if you want to encrypt multiple files with the same key. You can prefix the plain IV at the start of the ciphertext. It is always exactly one block (16 bytes) in size.
If you want to use a password, please make sure you do use a good key derivation mechanism (look up password based encryption or password based key derivation). PBKDF2 is the most commonly used Password Based Key Derivation scheme and it is present in most Java runtimes, including Android. Note that SHA-1 is a bit outdated hash function, but it should be fine in PBKDF2, and does currently present the most compatible option.
Always specify the character encoding when encoding/decoding strings, or you'll be in trouble when the platform encoding differs from the previous one. In other words, don't use String.getBytes()
but use String.getBytes(StandardCharsets.UTF_8)
.
To make it more secure, please add cryptographic integrity and authenticity by adding a secure checksum (MAC or HMAC) over the ciphertext and IV, preferably using a different key. Without an authentication tag the ciphertext may be changed in such a way that the change cannot be detected.
Be warned that CipherInputStream
may not report BadPaddingException
, this includes BadPaddingException
generated for authenticated ciphers such as GCM. This would make the streams incompatible and insecure for these kind of authenticated ciphers.
That is because Low
is a string.
.toFixed()
only works with a number.
Try doing:
Low = parseFloat(Low).toFixed(..);
If you debug, you will see that the string is actually "\ \r\ \n"
or "\ \n"
, ie, it is escaped. So if you massage that string, to get rid of the extra \
, you will have your solution. This is true especially if you are reading from a database.
You can also change the index name in column definitions within a create_table
block (such as you get from the migration generator).
create_table :studies do |t|
t.references :user, index: {:name => "index_my_shorter_name"}
end
If you want to serialize the ArrayList object to a file so you can read it back in again later use ObjectOuputStream/ObjectInputStream writeObject()/readObject() since ArrayList implements Serializable. It's not clear to me from your question if you want to do this or just write each individual item. If so then Andrey's answer will do that.
To have it in one line, this is what I did:
if any(([True if 'MICHAEL89' in username.upper() else False for username in USERNAMES])):
print('username exists in list')
I didn't test it time-wise though. I am not sure how fast/efficient it is.
Open your Android SDK Manager and ensure that you download/install a system image for the API level you are developing with.
I have used the following:
public static double Index2Freq(int i, double samples, int nFFT) {
return (double) i * (samples / nFFT / 2.);
}
public static int Freq2Index(double freq, double samples, int nFFT) {
return (int) (freq / (samples / nFFT / 2.0));
}
The inputs are:
i
: Bin to accesssamples
: Sampling rate in Hertz (i.e. 8000 Hz, 44100Hz, etc.)nFFT
: Size of the FFT vectorI handled tables for the German Government with sometimes 60 million records.
And we needed to know many times the total rows.
So we database programmers decided that in every table is record one always the record in which the total record numbers is stored. We updated this number, depending on INSERT or DELETE rows.
We tried all other ways. This is by far the fastest way.
Change this:
public FrameForm() {
initComponents();
}
to this:
public FrameForm() {
initComponents();
this.setLocationRelativeTo(null);
}
try this code I think it is more optimal.
HeaderRow is used to repeat the header of the table for each new page automatically
BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

I was facing the same problem under Windows7. The error message looks like that:
Fatal Python error: Py_Initialize: unable to load the file system codec ModuleNotFoundError: No module named 'encodings' Current thread 0x000011f4 (most recent call first):
I have installed python 2.7(uninstalled now), and I checked "Add Python to environment variables in Advanced Options" while installing python 3.6. It comes out that the Environment Variable "PYTHONHOME" and "PYTHONPATH" is still python2.7.
Finally I solved it by modify "PYTHONHOME" to python3.6 install path and remove variable "PYTHONPATH".
Just check the packaging, the simplest answer I can provide is that your package has been mislabeled (within a class).
Also, you may have some weird characters. Try white-flushing the code in a Notepad (or Gedit) and then pasting it into a newly created class with your IDE.

# 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

Inline elements:
Block elements:
Inline-block elements:
From W3Schools:
An inline element has no line break before or after it, and it tolerates HTML elements next to it.
A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.
An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

when curl
is used to download a large file then CURLOPT_TIMEOUT
is the main option you have to set for.
CURLOPT_RETURNTRANSFER
has to be true in case you are getting file like pdf/csv/image etc.
You may find the further detail over here(correct url) Curl Doc
From that page:
curl_setopt($request, CURLOPT_TIMEOUT, 300); //set timeout to 5 mins
curl_setopt($request, CURLOPT_RETURNTRANSFER, true); // true to get the output as string otherwise false
You should take a look at library called async

Recently, I explored the possibilities to parameterize the folder to scan through and the place where the result of recursive scan will be stored. At the end, I also did summarize the number of folders scanned and number of files inside as well. Sharing it with community in case it may help other developers.
##Script Starts
#read folder to scan and file location to be placed
$whichFolder = Read-Host -Prompt 'Which folder to Scan?'
$whereToPlaceReport = Read-Host -Prompt 'Where to place Report'
$totalFolders = 1
$totalFiles = 0
Write-Host "Process started..."
#IMP separator ? : used as a file in window cannot contain this special character in the file name
#Get Foldernames into Variable for ForEach Loop
$DFSFolders = get-childitem -path $whichFolder | where-object {$_.Psiscontainer -eq "True"} |select-object name ,fullName
#Below Logic for Main Folder
$mainFiles = get-childitem -path "C:\Users\User\Desktop" -file
("Folder Path" + "?" + "Folder Name" + "?" + "File Name " + "?"+ "File Length" )| out-file "$whereToPlaceReport\Report.csv" -Append
#Loop through folders in main Directory
foreach($file in $mainFiles)
{
$totalFiles = $totalFiles + 1
("C:\Users\User\Desktop" + "?" + "Main Folder" + "?"+ $file.name + "?" + $file.length ) | out-file "$whereToPlaceReport\Report.csv" -Append
}
foreach ($DFSfolder in $DFSfolders)
{
#write the folder name in begining
$totalFolders = $totalFolders + 1
write-host " Reading folder C:\Users\User\Desktop\$($DFSfolder.name)"
#$DFSfolder.fullName | out-file "C:\Users\User\Desktop\PoC powershell\ok2.csv" -Append
#For Each Folder obtain objects in a specified directory, recurse then filter for .sft file type, obtain the filename, then group, sort and eventually show the file name and total incidences of it.
$files = get-childitem -path "$whichFolder\$($DFSfolder.name)" -recurse
foreach($file in $files)
{
$totalFiles = $totalFiles + 1

Sounds like an ideal application for RegEx -- an engine designed for fast text manipulation. In this case:
Regex.Replace("He\"ll,o Wo'r.ld", "[@,\\.\";'\\\\]", string.Empty)
Following example uses InputBox method to validate user entry to unhide sheets: Important thing here is to use wrap InputBox variable inside StrPtr so it could be compared to '0' when user chose to click 'x' icon on the InputBox.
Sub unhidesheet()
Dim ws As Worksheet
Dim pw As String
pw = InputBox("Enter Password to Unhide Sheets:", "Unhide Data Sheets")
If StrPtr(pw) = 0 Then
Exit Sub
ElseIf pw = NullString Then
Exit Sub
ElseIf pw = 123456 Then
For Each ws In ThisWorkbook.Worksheets
ws.Visible = xlSheetVisible
Next

| $ | A global variable |
| @ | An instance variable |
| [a-z] or _ | A local variable |
| [A-Z] | A constant |

In my opinion this solution is very nice:
$("#dialog").dialog({
open: function(event, ui) {
$("input").blur();
}
});

This questions appears in quite a few SO discussions:
Different solutions are proposed, but none are optimal. Luckily, science comes to the rescue
Arbitrary N
The last 2 will be free via most university libraries / proxies.
N is finite and relatively small
In this case, one could go for a list solution. A very interesting article in the subject is freely available:
There are several color lists to consider:
I also ran into this Palette by an MIT student. Lastly, The following links may be useful in converting between different color systems / coordinates (some colors in the articles are not specified in RGB, for instance):
For Kelly's and Boynton's list, I've already made the conversion to RGB (with the exception of white and black, which should be obvious). Some C# code:

}
private static readonly List<Color> _kellysMaxContrastSet = new List<Color>

An immutable object is an object whose state cannot be modified after it is created.
So a = "ABC"
<-- immutable object. "a" holds reference to the object.
And, a = "DEF"
<-- another immutable object, "a" holds reference to it now.
Once you assign a string object, that object can not be changed in memory.
In summary, what you did is to change the reference of "a" to a new string object.
If I understood correctly, I would change the HTML to something like this:
<div id="shop">
<div class="content">
<img src="http://placehold.it/182x121"/>
<a href="#">Counter-Strike 1.6 Steam</a>
</div>
</div>
Then I would be able to use position:absolute
and position:relative
to force the blue button down.
I have created a jsfiddle: http://jsfiddle.net/y9w99/
Even though this question is old, I'll quickly mention that I've thrown together an ActionSheetPicker class with a convenience function, so you can spawn an ActionSheet with a UIPickerView in one line. It's based on code from answers to this question.
Edit: It now also supports the use of a DatePicker and DistancePicker.
Thinking about it in general, I would strongly consider hiding coordinate system behind well-designed abstraction. Quoting Uncle Bob and his book:
class Point(object)
def setCartesian(self, x, y)
def setPolar(self, rho, theta)
def getX(self)
def getY(self)
def getRho(self)
def setTheta(self)
With interface like that any user of Point class may choose convenient representation, no explicit conversions will be performed. All this ugly sines, cosines etc. will be hidden in one place. Point class. Only place where you should care which representation is used in computer memory.
If you created your database following this tutorial: https://msdn.microsoft.com/en-au/data/jj193542.aspx

An additional reason could be that you're pointing to a workspace on a drive that no longer exists, thinking that you're choosing the valid one. For instance, for me the workspace used to exist on the F drive, but now it is on my D drive. Even though I don't have the F drive anymore it is still listed as a workspace I once used during Eclipse startup. When I choose this old workspace Eclipse complains that the workspace is "in use", which is very strange.
The script from gombosg is much better then npm-check.

One lesser known facet of switch in C# is that it relies on the operator= and since it can be overriden you could have something like this:
string s = foo();
switch (s) {
case "abc": /*...*/ break;
case "def": /*...*/ break;
}
When I find myself doing a lot of string concatenation in JavaScript, I start looking for templating. Handlebars.js works quite well keeping the HTML and JavaScript more readable. http://handlebarsjs.com
Use this method and pass your array in parameter
Collections.shuffle(arrayList);
This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.
You can now use arraylist which is shuffled.
Not saying this is the best way to go, but its good to have options. Necessitas is a project that ports Qt to android. It is still in its early stages and lacking full features, but for those who know Qt and don't wanna bother with the terrible lack of good tools for Android UI would be wise to at least consider using this.
The auto keyword gets the type from the expression on the right of =. Therefore it will work with any type, the only requirement is to initialize the auto variable when declaring it so that the compiler can deduce the type.
Examples:
auto a = 0.0f; // a is float
auto b = std::vector<int>(); // b is std::vector<int>()
MyType foo() { return MyType(); }
auto c = foo(); // c is MyType
var seconds = 0;
setInterval(function () {
seconds++;
}, 1000);
There you go, now you have a variable counting seconds elapsed. Since I don't know the context, you'll have to decide whether you want to attach that variable to an object or make it global.
Set interval is simply a function that takes a function as it's first parameter and a number of milliseconds to repeat the function as it's second parameter.
You could also solve this by saving and comparing times.
EDIT: This answer will provide very inconsistent results due to things such as the event loop and the way browsers may choose to pause or delay processing when a page is in a background tab. I strongly recommend using the accepted answer.
I tried the program below and saw different string each time
package main
import (
"fmt"
"math/rand"
"time"
)
func RandomString(count int){
rand.Seed(time.Now().UTC().UnixNano())
for(count > 0 ){
x := Random(65,91)
fmt.Printf("%c",x)
count--;
}
}
func Random(min, max int) (int){
return min+rand.Intn(max-min)
}
func main() {
RandomString(12)
}
And the output on my console is
D:\james\work\gox>go run rand.go
JFBYKAPEBCRC
D:\james\work\gox>go run rand.go

If for some reason you're intent on using Date
objects for your solution, you'll need to do something like this:
// Convert user input into year, month, and day integers
Date toDate = new Date(year - 1900, month - 1, day + 1);
Date currentDate = new Date();
boolean runThatReport = toDate.after(currentDate);
Shifting the toDate
ahead to midnight of the next day will take care of the bug I've whined about in the comments to other answers. But, note that this approach uses a deprecated constructor; any approach relying on Date
will use one deprecated method or another, and depending on how you do it may lead to race conditions as well (if you base toDate
off of new Date()
and then fiddle around with the year, month, and day, for instance). Use Calendar
, as described elsewhere.
In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:
public class CustomRunner extends BlockJUnit4ClassRunner {
public CTRunner(Class<?> klass) throws initializationError {
super(klass);
}
@Override
protected boolean isIgnored(FrameworkMethod child) {
if(shouldIgnore()) {
return true;
}
return super.isIgnored(child);
}
private boolean shouldIgnore(class) {
/* some custom criteria */
}
}
The 'Z' is what adds the timezone info. As for output UTC, that seems to be the subject of some confusion -- people seem to gravitate toward moment.js.
Borrowing from this answer, you could do something like this without moment.js:
controller
var app1 = angular.module('app1',[]);
app1.controller('ctrl',['$scope',function($scope){
var toUTCDate = function(date){
var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
return _utc;
};
var millisToUTCDate = function(millis){
return toUTCDate(new Date(millis));
};
$scope.toUTCDate = toUTCDate;
$scope.millisToUTCDate = millisToUTCDate;
}]);
template
<html ng-app="app1">
<head>
<script data-require="angular.js@*" data-semver="1.2.12" src="http://code.angularjs.org/1.2.12/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
<div ng-controller="ctrl">
<div>
utc {{millisToUTCDate(1400167800) | date:'dd-M-yyyy H:mm'}}
</div>
<div>
local {{1400167800 | date:'dd-M-yyyy H:mm'}}
</div>
</div>
</body>
</html>
here's plunker to play with it
Also note that with this method, if you use the 'Z' from Angular's date filter, it seems it will still print your local timezone offset.
You could do it like this:
String s = "1234567890";
System.out.println(java.util.Arrays.toString(s.split("(?<=\\G...)")));
which produces:
[123, 456, 789, 0]
The regex (?<=\G...)
matches an empty string that has the last match (\G
) followed by three characters (...
) before it ((?<= )
)
This will tell you what line is the problem.
import csv
lines = []
with open('output.txt','r') as f:
for line in f.readlines():
lines.append(line[:-1])
with open('corrected.csv','w') as correct:
writer = csv.writer(correct, dialect = 'excel')
with open('input.csv', 'r') as mycsv:
reader = csv.reader(mycsv)
try:
for i, row in enumerate(reader):
if row[0] not in lines:
writer.writerow(row)
except csv.Error:
print('csv choked on line %s' % (i+1))
raise
Perhaps this from daniweb would be helpful:
I'm getting this error when reading from a csv file: "Runtime Error! line contains NULL byte". Any idea about the root cause of this error?
...
Ok, I got it and thought I'd post the solution. Simply yet caused me grief... Used file was saved in a .xls format instead of a .csv Didn't catch this because the file name itself had the .csv extension while the type was still .xls
To get the filter method from user1106925 working in <=IE11 if needed
You can replace the spread operator with:
[].slice.call(document.querySelectorAll("a"))
and the includes call with a.textContent.match("your search term")
which works pretty neatly:
[].slice.call(document.querySelectorAll("a"))
.filter(a => a.textContent.match("your search term"))
.forEach(a => console.log(a.textContent))
var lat = homeMarker.getPosition().lat();
var lng = homeMarker.getPosition().lng();

Functional languages use a different paradigm than imperative and object-oriented languages. They use side-effect-free functions as a basic building block in the language. This enables lots of things and makes a lot of things more difficult (or in most cases different from what people are used to).
One of the biggest advantages with functional programming is that the order of execution of side-effect-free functions is not important. For example, in Erlang this is used to enable concurrency in a very transparent way. And because functions in functional languages behave very similar to mathematical functions it's easy to translate those into functional languages. In some cases, this can make code more readable.
Traditionally, one of the big disadvantages of functional programming was also the lack of side effects. It's very difficult to write useful software without IO, but IO is hard to implement without side effects in functions. So most people never got more out of functional programming than calculating a single output from a single input. In modern mixed-paradigm languages like F# or Scala this is easier.
Lots of modern languages have elements from functional programming languages. C# 3.0 has a lot functional programming features and you can do functional programming in Python too. I think the reasons for the popularity of functional programming is mostly because of two reasons: Concurrency is getting to be a real problem in normal programming because we're getting more and more multiprocessor computers; and the languages are getting more accessible.
You should use the StringBuilder class.
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("Some text");
stringBuilder.append("Some text");
stringBuilder.append("Some text");
String finalString = stringBuilder.toString();
In addition, please visit:
In Windows (command prompt) you can use CertUtil, here is the syntax:
CertUtil [Options] -hashfile InFile [HashAlgorithm]
for syntax explanation type in cmd:
CertUtil -hashfile -?
example:
CertUtil -hashfile C:\myFile.txt MD5
default is SHA1 it supports: MD2, MD4, MD5, SHA1, SHA256, SHA384, SHA512. Unfortunately no CRC32 as Unix shell does.

To get rid of the bad looking datepicker you need to add jquery-ui css
<link rel="stylesheet" type="text/css" href="https://code.jquery.com/ui/1.12.0/themes/smoothness/jquery-ui.css">
While it was discussed in the comments, there isn't an answer containing it yet, so it can be easy to miss. DATE_FORMAT works really well and is flexible to handle many different patterns.
DATE_FORMAT(date,'%Y%m')
To put it in a query:
SELECT DATE_FORMAT(test_date,'%Y%m') AS date FROM test_table;
You can query the whole tag, or just the specific value. Here I use a wildcard for the xml namespaces.
declare @myDoc xml
set @myDoc =
'<Root xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://stackoverflow.com">
<Child>my value</Child>
</Root>'
select @myDoc.query('/*:Root/*:Child') -- whole tag
select @myDoc.value('(/*:Root/*:Child)[1]', 'varchar(255)') -- only value
Try this:
import pytz
import datetime
fmt = '%Y-%m-%d %H:%M:%S %Z'
d = datetime.datetime.now(pytz.timezone("America/New_York"))
d_string = d.strftime(fmt)
d2 = pytz.timezone('America/New_York').localize(d.strptime(d_string,fmt), is_dst=None)
print(d_string)
print(d2.strftime(fmt))
Any how myMethod() should return a String value .what if your condition is false is myMethod return anything? ans is no so you need to define return null or some string value in false condition
public String myMethod() {
boolean c=true;
if (conditions) {
return "d";
}
return null;//or some other string value
}

Making methods synchronized has two effects:
First, it is not possible for two invocations of synchronized methods on the same object to interleave. When one thread is executing a synchronized method for an object, all other threads that invoke synchronized methods for the same object block (suspend execution) until the first thread is done with the object.
Second, when a synchronized method exits, it automatically establishes a happens-before relationship with any subsequent invocation of a synchronized method for the same object. This guarantees that changes to the state of the object are visible to all threads
Have a look at this documentation page to understand intrinsic locks and lock behavior.
This will answer your question: On same object x , you can't call x.addA() and x.addB() at same time when one of the synchronized methods execution is in progress.
Maybe you could try this:
catch(Exception e)
{
StringWriter writer = new StringWriter();
PrintWriter pw = new PrintWriter(writer);
e.printStackTrace(pw);
String errorDetail = writer.toString();
}
The string 'errorDetail' contains the stacktrace.
Maybe I'm a bit of late to answer this question, but I'm working on this subject at my job :)
I wanted to write column 'a_code' = c1,c2,c3,c4...
Firstly I opened a column with the name ref_id
and the type serial
.
Then I solved my problem with this command:
update myschema.mytable set a_code=cast('c'||"ref_id" as text)
Your code would be like this:
int *p = (int *)0x28ff44;
int
needs to be the type of the object that you are referencing or it can be void
.
But be careful so that you don't try to access something that doesn't belong to your program.
The relative pathing is based on the document level of the client side i.e. the URL level of the document as seen in the browser.
If the URL of your website is: http://www.example.com/mywebsite/
then starting at the root level starts above the "mywebsite" folder path.

I know this thread is old but I just wanted to add this answer for those who believe it's safer to Alter
than Drop
and Create
. The below will Alter
the Function
if it exists or Create
it if doesn't:
IF NOT EXISTS (SELECT *
FROM sys.objects
WHERE object_id = OBJECT_ID(N'[dbo].[foo]')
AND type IN ( N'FN', N'IF', N'TF', N'FS', N'FT' ))
EXEC('CREATE FUNCTION [dbo].[foo]() RETURNS INT AS BEGIN RETURN 0 END')
GO
ALTER FUNCTION [dbo].[foo]
AS

The first time I struggled with mod_rewrite rules ignoring my traffic, I learned (frustratingly) that I had placed them in the wrong <VirtualHost>
, which meant that my traffic would ignore all of them no matter how well-written they were. Make sure this isn't happening to you:
# Change the log location to suit your system.
RewriteLog /var/log/apache-rw.log
RewriteLogLevel 2
These parameters will activate if you perform a graceful restart of Apache, so you can recycle them in and closely monitor the mod_rewrite behavior. Once your problem is fixed, turn the RewriteLogLevel back down and celebrate.
In 100% of my experience, I've found that the RewriteLog has helped me discover the problem with my rewrite rules. I can't recommend this enough. Good luck in your troubleshooting!
Also, this bookmark is your best friend: http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewritelog

Super key: super key is a set of atttibutes in a relation(table).which can define every tupple in the relation(table) uniquely.
Candidate key: we can say minimal super key is candidate key. Candidate is the smallest sub set of super key. And can uniquely define each and every tupple.
You can try this:
SELECT * FROM MYTABLE WHERE DATE BETWEEN '03/10/2014 06:25:00' and '03/12/2010 6:25:00'

Do an svn update in the trunk, note the revision number.
From the trunk:
svn merge -r<revision where branch was cut>:<revision of trunk> svn://path/to/branch/branchName
You can check where the branch was cut from the trunk by doing an svn log
svn log --stop-on-copy

We open a terminal and look for the location of java:
manuel@zonademanel:~ ? whereis java
java: /usr/bin/java /etc/java /usr/bin/X11/java /usr/share/java /usr/share/man/man1/java.1.gz
What we are looking for is /usr/bin/java continue on the command line to find the absolute path , as this is only a symbolic link.
manuel@zonademanel:~ ? ls -lah /usr/bin/java
lrwxrwxrwx 1 root root 22 may 19 2015 /usr/bin/java -> /etc/alternatives/java

lrwxrwxrwx 1 root root 39 dic 7 11:52 /etc/alternatives/java -> /usr/lib/jvm/java-8-oracle/jre/bin/java
I modified my /etc/environment file with the following values

option.
Make sure you put double quotes around the path. Other people didn't mention that and it made me stuck for 2 days. So this answer is for people who are very new to CMake and very confused.

The input of this function can be everything!
Finds whether the given variable is numeric. Numeric strings consist of optional sign, any number of digits, optional decimal part and optional exponential part. Thus +0123.45e6 is a valid numeric value. Hexadecimal (e.g. 0xf4c3b00c) and binary (e.g. 0b10100111001) notation is not allowed.

Some good answers here but none cover the case of your start time being in a different day than your end time. If you need to straddle the day boundary, then something like this may help:
TimeSpan start = TimeSpan.Parse("22:00"); // 10 PM
TimeSpan end = TimeSpan.Parse("02:00"); // 2 AM
TimeSpan now = DateTime.Now.TimeOfDay;
if (start <= end)
{
// start and stop times are in the same day
if (now >= start && now <= end)
{
// current time is between start and stop
}
}
else
{
// start and stop times are in different days
if (now >= start || now <= end)
{
// current time is between start and stop
}
}
Note that in this example the time boundaries are inclusive and that this still assumes less than a 24-hour difference between start
and stop
.
You can use setScale() e.g.
double d = ...
BigDecimal db = new BigDecimal(d).setScale(12, BigDecimal.ROUND_HALF_UP);
One reason that the designers c# might have chosen to NOT have enums auto convert was to prevent accidentally mixing different enum types...
e.g. this is bad code followed by a good version
enum ParkingLevel { GroundLevel, FirstFloor};
enum ParkingFacing { North, East, South, West }
void Test()
{
var parking = ParkingFacing.North; // NOT A LEVEL
// WHOOPS at least warning in editor/compile on calls
WhichLevel(parking);
// BAD wrong type of index, no warning
var info = ParkinglevelArray[ (int)parking ];
}
// however you can write this, looks complicated
// but avoids using casts every time AND stops miss-use
void Test()
{
ParkingLevelManager levels = new ParkingLevelManager();
// assign info to each level
var parking = ParkingFacing.North;
// Next line wrong mixing type
// but great you get warning in editor or at compile time
var info=levels[parking];
// and.... no cast needed for correct use
var pl = ParkingLevel.GroundLevel;
var infoCorrect=levels[pl];
}
class ParkingLevelInfo { /*...*/ }
class ParkingLevelManager
{
List<ParkingLevelInfo> m_list;
public ParkingLevelInfo this[ParkingLevel x]
{ get{ return m_list[(int)x]; } }}

If you do not want to configure the message converters yourself, you can use either @EnableWebMvc or <mvc:annotation-driven />, add Jackson to the classpath and Spring will give you both JSON, XML (and a few other converters) by default. Additionally, you will get some other commonly used features for conversion, formatting and validation.
It was an exercise in codecademy and that's how i passed it below...
def is_prime(x):
# If number(x) is evenly divided by following dividers then number(x) is not prime
divider = [2, 3, 5, 7]
# An empty list to be able to check whether number(x) is evenly divided:
remainder = []
# exceptions for numbers 1,2,3,5,7:
if x < 2:
return False
if x in divider:
return True
else:
for nums in divider:
remainder.append(x % nums)
if 0 in remainder:
return False
else:
return True
use
<option selected="true" disabled="disabled">Choose Tagging</option>

This function will inject css whenever you call the function appendStyle
like this:
appendStyle('css you want to inject')
This works by injecting a style
node into the head of the document. This is a similar technique to what is commonly used to lazy-load JavaScript.
It works consistently in most modern browsers.
appendStyle = function (content) {_x000D_
style = document.createElement('STYLE');_x000D_
style.type = 'text/css';_x000D_
style.appendChild(document.createTextNode(content));_x000D_
document.head.appendChild(style);_x000D_
}
_x000D_
<!DOCTYPE html>_x000D_
<html lang="en">_x000D_
_x000D_
<head>_x000D_
<meta charset="UTF-8">_x000D_
<meta name="viewport" content="width=device-width, initial-scale=1.0">_x000D_
</head>_x000D_
<body>_x000D_
<h1>Lorem Ipsum</h1>_x000D_
<p>dolar sit amet</p>_x000D_
<button onclick='appendStyle("body { background-color: #ff0000;}h1 { font-family: Helvetica, sans-serif; font-variant: small-caps; letter-spacing: 3px; color: #ff0000; background-color: #000000;}p { font-family: Georgia, serif; font-size: 14px; font-style: normal; font-weight: normal; color: #000000; background-color: #ffff00;}")'>Press me to inject CSS!</button>_x000D_
</body>_x000D_
_x000D_
</html>
_x000D_
You can also lazy-load external CSS files by using the following snippet:
appendExternalStyle = function (content) {_x000D_
link = document.createElement('LINK');_x000D_
link.rel = 'stylesheet';_x000D_
link.href = content;_x000D_
link.type = 'text/css';_x000D_
document.head.appendChild(link);_x000D_
}
_x000D_
<!DOCTYPE html>_x000D_

With React 16.8. We can do this with hooks like the following example
import React, { useState } from "react";
import "./styles.css";
export default function App() {
const options = [
"Monty Python and the Holy Grail",
"Monty Python's Life of Brian",
"Monty Python's The Meaning of Life"
];
const filmsByTati = [
{
id: 1,
title: "Jour de fête",
releasedYear: 1949
},
{
id: 2,
title: "Play time",
releasedYear: 1967
},
{
id: 3,
releasedYear: 1958,
title: "Mon Oncle"
}
];
const [selectedOption, setSelectedOption] = useState(options[0]);
const [selectedTatiFilm, setSelectedTatiFilm] = useState(filmsByTati[0]);
return (
<div className="App">
<h1>Select Example</h1>
<select
value={selectedOption}
onChange={(e) => setSelectedOption(e.target.value)}
>
{options.map((option) => (
<option key={option} value={option}>

</option>
))}
</select>
<span>Selected option: {selectedOption}</span>
<select
value={selectedTatiFilm}
onChange={(e) =>
setSelectedTatiFilm(
filmsByTati.find(film => (film.id == e.target.value))
)
}
>
{filmsByTati.map((film) => (
<option key={film.id} value={film.id}>
{film.title}
</option>
))}
</select>
<span>Selected option: {selectedTatiFilm.title}</span>
</div>
);
}
hifarrer's full solution is very helpful to me.
but, I met many other problems - supporting other mime type, listing capture devices(camera, video, audio recoder), opening capture device immediately(ex: <input accept="image/*;capture"> )...
So, I made a solution that works exactly same as default web browser app.

UPDATE #1 (2015.09.09)
adds code for Android 5.0.1 compatability.
There are very few cases where you want to use except:
. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit
and KeyboardInterupt
, which can make your program annoying to use..
At the very simplest, you would catch urllib2.URLError
:
try:
urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
raise MyException("There was an error: %r" % e)
The following should capture the specific error raised when the connection times out:
import urllib2
import socket
class MyException(Exception):
pass
try:
urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
# For Python 2.6
if isinstance(e.reason, socket.timeout):
raise MyException("There was an error: %r" % e)
else:
# reraise the original error
raise
except socket.timeout, e:
# For Python 2.7
raise MyException("There was an error: %r" % e)
You can use the rpad
and lpad
functions to pad numbers to the right or to the left, respectively. Note that this does not work directly on numbers, so you'll have to use ::char
or ::text
to cast them:
SELECT RPAD(numcol::text, 3, '0'), -- Zero-pads to the right up to the length of 3
LPAD(numcol::text, 3, '0'), -- Zero-pads to the left up to the length of 3
FROM my_table
@FlySwat already gave the correct answer, I am just sharing the complete answer:
Use ClipboardManager.setPrimaryClip (http://developer.android.com/reference/android/content/ClipboardManager.html) method:
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText("label", "Text to copy");
clipboard.setPrimaryClip(clip);
Where label
is a User-visible label for the clip data and
text
is the actual text in the clip. According to official docs.
It is important to use this import:
import android.content.ClipboardManager;
I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)
The screen you show is DateTimeSettings
. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time";
and also to Settings.System.AUTO_TIME
This settings is observed by an observed called mAutoTimeObserver
in the 2 network ServiceStateTracker
s:
GsmServiceStateTracker
and CdmaServiceStateTracker
.
Both implementations call a method called revertToNitz()
when the settings becomes true.
Apparently NITZ is the equivalent of NTP in the carrier world.
Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz()
.
Unfortunately, I haven't found a mechanism to get the network time.
If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTracker
s implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime
.
"preflighted" requests first send an HTTP request by the OPTIONS method to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests

If you by any means searched this topic because of the post page (index page alternative when using static front page), then the right answer is this:
if (get_option('show_on_front') == 'page') {
$page_id = get_option('page_for_posts');
echo get_the_title($page_id);
}
(taken from Forrst | Echo WordPress "Posts Page" title - Some code from tammyhart)
You can do it like this:
angular.element('#modal').modal('hide');
There is such a confusion on this question, as there is way too much complexity in this question. First MacOS vs. Win10. Then the different auth mechanisms.
I will start a consolidated answer here and probably need some help, if I do not get help, I will keep working on the answer until it is complete, but that will take time.
Windows 10: |
|-- Run this command. You will be prompted on next push/pull to enter username and password:
| git config --global credential.helper wincred (Thanks to @Andrew Pye)
` MacOS:

| git config --global --add user.password
|
|---- first time entry
| git config --global --add user.password <new_pass>
|
|---- password update

Maybe the example with an clock could help you understand the modulo.
A familiar use of modular arithmetic is its use in the 12-hour clock, in which the day is divided into two 12 hour periods.
Lets say we have currently this time: 15:00
But you could also say it is 3 pm
This is exactly what modulo does:
15 / 12 = 1, remainder 3
You find this example better explained on wikipedia: Wikipedia Modulo Article
You can use something like this:
<?php
array_walk_recursive(
$array, function (&$value)
{
$value = htmlspecialchars(html_entity_decode($value, ENT_QUOTES, 'UTF-8'), ENT_QUOTES, 'UTF-8');
}
);
?>
To answer your questions in a easy way:
a) String.length();
b) String.charAt(/* String index */);
See if this helps: Back to CSV - Convert CSV text to Objects; via JSON
This is a blog post published in November 2008 that includes C# code to provide a solution.
From the intro on the blog post:
As Json is easier to read and write then Xml. It follows that CSV (comma seperated values) is easier to read and write then Json. CSV also has tools such as Excel and others that make it easy to work with and create. So if you ever want to create a config or data file for your next app, here is some code to convert CSV to JSON to POCO objects
you can do it like this:
function MyClass() {
this.abc = function() {
alert("abc");
}
}
var myObject = new MyClass();
myObject["abc"]();
Here is what I had and what caused my "incomplete type error":
#include "X.h" // another already declared class
class Big {...} // full declaration of class A
class Small : Big {
Small() {}
Small(X); // line 6
}
//.... all other stuff
What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..
Small::Big(X my_x) { // line 9 <--- LOOK at this !
}
I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..
Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.
One way that I've found really useful in situations like this is to go old-school and use the Jet OLEDB provider, together with a schema.ini file to read large tab-delimited files in using ADO.Net. Obviously, this method is really only useful if you know the format of the file to be imported.
public void ImportCsvFile(string filename)
{
FileInfo file = new FileInfo(filename);
using (OleDbConnection con =
new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\"" +
file.DirectoryName + "\";
Extended Properties='text;HDR=Yes;FMT=TabDelimited';"))
{
using (OleDbCommand cmd = new OleDbCommand(string.Format
("SELECT * FROM [{0}]", file.Name), con))
{
con.Open();
// Using a DataReader to process the data
using (OleDbDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
// Process the current reader entry...
}
}
// Using a DataTable to process the data
using (OleDbDataAdapter adp = new OleDbDataAdapter(cmd))
{
DataTable tbl = new DataTable("MyTable");
adp.Fill(tbl);
foreach (DataRow row in tbl.Rows)
{
// Process the current row...
}
}
}
}
}
Once you have the data in a nice format like a datatable, filtering out the data you need becomes pretty trivial.
Noticed your comment about using it for email validation and needing a plugin, the validation plugin may help you, its located at http://bassistance.de/jquery-plugins/jquery-plugin-validation/, it comes with a e-mail rule as well.
This has only been tested on Windows:
You can do the following:
import os
os.startfile("C:/Users/TestFile.txt", "print")
This will start the file, in its default opener, with the verb 'print', which will print to your default printer.Only requires the os
module which comes with the standard library
Use DATE_FORMAT function to change the format.
SELECT DATE_FORMAT(CURDATE(), '%d/%m/%Y')
SELECT DATE_FORMAT(column_name, '%d/%m/%Y') FROM tablename

Use This code ..to change action bar background color. open "res/values/themes.xml" (if not present, create it) and add

<style name="CustomActionBarTheme"
parent="@android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar"
parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">

\d+
\d
represents any digit, +
for one or more. If you want to catch negative numbers as well you can use -?\d+
.
Note that as a string, it should be represented in C# as "\\d+"
, or @"\d+"
For excluding one or more library globally add the following to your build.gradle
configurations.all {
exclude group:"org.apache.geronimo.specs", module: "geronimo-servlet_2.5_spec"
exclude group:"ch.qos.logback", module:"logback-core"
}
Now the exclude block has two properties group and module. For those of you coming from maven background, group is same as groupId and module is same as artifactId. Example: To exclude com.mchange:c3p0:0.9.2.1 following should be exclude block
exclude group:"com.mchange", module:"c3p0"
A quick and dirty way is to find out the class of the footer and hide it using jQuery or CSS:
$(".dataTables_info").hide();
Using ASP.Net Post call, this worked for me.
StringBuilder getNewToken = new StringBuilder();
getNewToken.Append("https://www.googleapis.com/oauth2/v4/token");
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(getNewToken.ToString());
var values = new Dictionary<string, string>
{
{ "client_id", <Your Client Id> },
{ "client_secret", <Your Client Secret> },
{ "refresh_token", <Your Saved Refresh Token> },
{ "grant_type", "refresh_token"}
};
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync(getNewToken.ToString(), content);
You need to handle the AppDomain.AssemblyResolve or AppDomain.ReflectionOnlyAssemblyResolve events (depending on which load you're doing) in case the referenced assembly is not in the GAC or on the CLR's probing path.
Consider the following simple Python script:
import time
import sys
for i in range(5):
print(i),
#sys.stdout.flush()
time.sleep(1)
This is designed to print one number every second for five seconds, but if you run it as it is now (depending on your default system buffering) you may not see any output until the script completes, and then all at once you will see 0 1 2 3 4
printed to the screen.
This is because the output is being buffered, and unless you flush sys.stdout
after each print
you won't see the output immediately. Remove the comment from the sys.stdout.flush()
line to see the difference.
None of these answer were working for me on my macbook pro. So what i had to do was go to:
Preferences -> Source Code -> Code Formatting -> C# source code.
From here I could change my style and spacing tabs etc. This is the only project i have where the lead developer has different formatting than i do. It was a pain in the butt that my IDE would format my code different than theirs.
An English dictionary defines the words append
and extend
as:
append: add (something) to the end of a written document.
extend: make larger. Enlarge or expand
With that knowledge, now let's understand
1) The difference between append
and extend
append
:
extend
:
list(iterable)
.2) Similarity between append
and extend
None
.Example
lis = [1, 2, 3]
# 'extend' is equivalent to this
lis = lis + list(iterable)
# 'append' simply appends its argument as the last element to the list
# as long as the argument is a valid Python object
list.append(object)
If you are using debug configuration for maven, use the command
clean install
And skip all the tests.
I've had similar problem in my software. We've wanted to merge several PDF files into one PDF file and submit it to an outer service. We've been using the FPDI solution as shown in Christa's solution.
However, the input PDF's we've been using could be in version higher than 1.7. We've decided to evaluate the FPDI commercial add-on. However, it turned out that some of the documents scanned by our office copier were having malformed indexes, which crashed the commercial FPDI add-on. So we've decided to use Ghostscript solution as in Chauhan's answer.
But then we got some strange metadata in the output PDF properties.
Finally we've decided to join two solutions to get PDF's merged and downgraded by Ghostscript, but the metadata is set by FPDI. We don't know yet how it would work with some advanced formatted pdfs, but for scans we use it works just fine. Here's our class excerpt:
class MergedPDF extends \FPDI
{
private $documentsPaths = array();
public function Render()
{
$outputFileName = tempnam(sys_get_temp_dir(), 'merged');
// merge files and save resulting file as PDF version 1.4 for FPDI compatibility
$cmd = "/usr/bin/gs -q -dNOPAUSE -dBATCH -dCompatibilityLevel=1.4 -sDEVICE=pdfwrite -sOutputFile=$outputFileName";
foreach ($this->getDocumentsPaths() as $pdfpath) {
$cmd .= " $pdfpath ";
}
$result = shell_exec($cmd);
$this->SetCreator('Your Software Name');
$this->setPrintHeader(false);
$numPages = $this->setSourceFile($outputFileName);
for ($i = 1; $i <= $numPages; $i++) {
$tplIdx = $this->importPage($i);
$this->AddPage();
$this->useTemplate($tplIdx);
}
unlink($outputFileName);
$content = $this->Output(null, 'S');
return $content;
}
public function getDocumentsPaths()
{
return $this->documentsPaths;
}
public function setDocumentsPaths($documentsPaths)
{
$this->documentsPaths = $documentsPaths;
}
public function addDocumentPath($documentPath)
{
$this->documentsPaths[] = $documentPath;
}
}
The usage of this class is as follows:
$pdf = new MergedPDF();
$pdf->setTitle($pdfTitle);
$pdf->addDocumentPath($absolutePath1);
$pdf->addDocumentPath($absolutePath2);
$pdf->addDocumentPath($absolutePath3);
$tempFileName = tempnam(sys_get_temp_dir(), 'merged');
$content = $pdf->Render();
file_put_contents($tempFileName, $content);
I think when you define a function with "var foo = function() {...};
", the function is only defined after that line. In other words, try this:
var replaceHtmlEntites = (function() {
var translate_re = /&(nbsp|amp|quot|lt|gt);/g;
var translate = {
"nbsp": " ",
"amp" : "&",
"quot": "\"",
"lt" : "<",
"gt" : ">"
};
return function(s) {
return ( s.replace(translate_re, function(match, entity) {
return translate[entity];
}) );
}
})();
var cleanText = text.replace(/^\xa0*([^\xa0]*)\xa0*$/g,"");
cleanText = replaceHtmlEntities(text);
Edit: Also, only use "var
" the first time you declare a variable (you're using it twice on the cleanText
variable).
Edit 2: The problem is the spelling of the function name. You have "var replaceHtmlEntites =". It should be "var replaceHtmlEntities ="
A bit late to the party, but nevertheless...

You can hide header like this:
<Stack.Screen name="Login" component={Login} options={{headerShown: false}} />
$(window).height();
To set anything in the middle you can use CSS.
<style>
#divCentre
{
position: absolute;
left: 50%;
top: 50%;
width: 300px;
height: 400px;
margin-left: -150px;
margin-top: -200px;
}
</style>
<div id="divCentre">I am at the centre</div>
Can be very simplified like that :
input[type="checkbox"]{
outline:2px solid red;
outline-offset: -2px;
}
Works without any plugin :)
Verify the length
property of the array to be greater than 0
:
<p ng-if="post.capabilities.items.length > 0">
<strong>Topics</strong>:
<span ng-repeat="topic in post.capabilities.items">
{{topic.name}}
</span>
</p>
Arrays (objects) in JavaScript are truthy values, so your initial verification <p ng-if="post.capabilities.items">
evaluates always to true
, even if the array is empty.
This worked for me:
File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)
clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.
Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.
then in:
Run >> Edit Configurations
Add this line to VM Options:
--module-path /path/to/JavaFX/lib --add-modules=javafx.controls
(oh and don't forget to set the SDK)

If you want to read more about the used functions:
This should do it:

Here is an alternative.
var condition = true;
var props = {

var component = <div { ...props } />;
Or its inline version

The TextBoxFor
is a newer MVC input extension introduced in MVC2.
The main benefit of the newer strongly typed extensions is to show any errors / warnings at compile-time rather than runtime.
See this page.
http://weblogs.asp.net/scottgu/archive/2010/01/10/asp-net-mvc-2-strongly-typed-html-helpers.aspx
The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. See the result in this Pen.
.content { flex: 1; display: flex; height: 1px; }
.column { padding: 20px; border-right: 1px solid #999; overflow: auto; }
The trick seems to be that a scrollable panel needs to have a height
literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px
works. The flex-grow:1
will still size the panel to fit properly.
Itemgetter lets you to sort by multiple criteria / columns:
sorted_list = sorted(list_to_sort, key=itemgetter(2,0,1))
You can use os.listdir
for this purpose. If you only want files and not directories, you can filter the results using os.path.isfile
.
example:
files = os.listdir(os.curdir) #files and directories
or
files = filter(os.path.isfile, os.listdir( os.curdir ) ) # files only
files = [ f for f in os.listdir( os.curdir ) if os.path.isfile(f) ] #list comprehension version.
I will give a practical example in scraping web data using python, a lot of the times you will get keys with no values, in those cases you will get errors if you use dictionary['key'], whereas dictionary.get('key', 'return_otherwise') has no problems.
Similarly, I would use ''.join(list) as opposed to list[0] if you try to capture a single value from a list.
hope it helps.
[Edit] Here is a practical example:
Say, you are calling an API, which returns a JOSN file you need to parse. The first JSON looks like following:
{"bids":{"id":16210506,"submitdate":"2011-10-16 15:53:25","submitdate_f":"10\/16\/2011 at 21:53 CEST","submitdate_f2":"p\u0159ed 2 lety","submitdate_ts":1318794805,"users_id":"2674360","project_id":"1250499"}}
The second JOSN is like this:
{"bids":{"id":16210506,"submitdate":"2011-10-16 15:53:25","submitdate_f":"10\/16\/2011 at 21:53 CEST","submitdate_f2":"p\u0159ed 2 lety","users_id":"2674360","project_id":"1250499"}}
Note that the second JSON is missing the "submitdate_ts" key, which is pretty normal in any data structure.
So when you try to access the value of that key in a loop, can you call it with the following:
for item in API_call:
submitdate_ts = item["bids"]["submitdate_ts"]
You could, but it will give you a traceback error for the second JSON line, because the key simply doesn't exist.
The appropriate way of coding this, could be the following:
for item in API_call:
submitdate_ts = item.get("bids", {'x': None}).get("submitdate_ts")
{'x': None} is there to avoid the second level getting an error. Of course you can build in more fault tolerance into the code if you are doing scraping. Like first specifying a if condition
Although dated, not one answer on this thread can be used universally. Using rgba to create transparent color masks - that doesn't exactly explain how to do so with background images.

I recently came across the 'Box' library which does the same thing.
Installation command : pip install python-box
Example:
from box import Box
mydict = {"key1":{"v1":0.375,
"v2":0.625},
"key2":0.125,
}
mydict = Box(mydict)
print(mydict.key1.v1)
I found it to be more effective than other existing libraries like dotmap, which generate python recursion error when you have large nested dicts.
link to library and details: https://pypi.org/project/python-box/
SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.
For more detail you can refer the link.

using your comment about productCode (and assuming product code is a String) as reference...
for(Product p : productList){
s.put(p.getProductCode() , p);

If you comparing 2 arrays but values not in same index, then try this
var array1=[1,2,3,4]
var array2=[1,4,3,2]
var is_equal = array1.length==array2.length && array1.every(function(v,i) { return ($.inArray(v,array2) != -1)})
console.log(is_equal)

Just check that your packages.config
file is checked in (when excluded, there will be a red no-entry symbol shown in the explorer). For some bizarre reason mine was excluded and caused this issue.
React components expose all the standard Javascript mouse events in their top-level interface. Of course, you can still use :hover
in your CSS, and that may be adequate for some of your needs, but for the more advanced behaviors triggered by a hover you'll need to use the Javascript. So to manage hover interactions, you'll want to use onMouseEnter
and onMouseLeave
. You then attach them to handlers in your component like so:
<ReactComponent
onMouseEnter={() => this.someHandler}
onMouseLeave={() => this.someOtherHandler}
/>
You'll then use some combination of state/props to pass changed state or properties down to your child React components.
Try ContentTemplate:
<Button Grid.Row="2" Grid.Column="0" Width="20" Height="20"
Template="{StaticResource SomeTemplate}">
<Button.ContentTemplate>
<DataTemplate>
<Image Source="../Folder1/Img1.png" Width="20" />
</DataTemplate>
</Button.ContentTemplate>
</Button>
The *
character is not allowed in the path of the URL, but there is no problem using it in the query string:
http://localhost:3286/Search/?q=test*
It's not an encoding issue, the *
character has no special meaning in an URL, so it doesn't matter if you URL encode it or not. You would need to encode it using a different scheme, and then decode it.
For example using an arbitrary character as escape character:
query = query.Replace("x", "xxx").Replace("y", "xxy").Replace("*", "xyy");
And decoding:
query = query.Replace("xyy", "*").Replace("xxy", "y").Replace("xxx", "x");
Look up the man page for getcwd

Signed variables use one bit to flag whether they are positive or negative. Unsigned variables don't have this bit, so they can store larger numbers in the same space, but only nonnegative numbers, e.g. 0 and higher.

It should be available in php.ini file. You need to un-comment the line for curl extension:
;extension=php_curl.dll
^----- remove semi-colon
plt.hist(hmag, 30, range=[6.5, 12.5], facecolor='gray', align='mid')
The easiest solution is to create 3 divs
. One that will contain the other 2, the one with transparent background and the one with content. Make the first div's position relative and set the one with transparent background to negative z-index
, then adjust the position of the content to fit over the transparent background. This way you won't have issues with absolute positioning.
Select Into functionality only works for PL/SQL Block, when you use Execute immediate , oracle interprets v_query_str as a SQL Query string so you can not use into .will get keyword missing Exception. in example 2 ,we are using begin end; so it became pl/sql block and its legal.
If you put overflow: scroll
on a fixed height div
, the div
will scroll if the contents take up too much space.
Here is a snippet code through a chain of environments properties files are being loaded for different environments.
Properties file under your application resources ( src/main/resources ):-
1. application.properties
2. application-dev.properties
3. application-uat.properties
4. application-prod.properties
Ideally, application.properties contains all common properties which are accessible for all environments and environment related properties only works on specifies environment. therefore the order of loading these properties files will be in such way -
application.properties -> application.{spring.profiles.active}.properties.
Code snippet here :-
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
public class PropertiesUtils {
public static final String SPRING_PROFILES_ACTIVE = "spring.profiles.active";
public static void initProperties() {
String activeProfile = System.getProperty(SPRING_PROFILES_ACTIVE);
if (activeProfile == null) {
activeProfile = "dev";
}
PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer
= new PropertySourcesPlaceholderConfigurer();
Resource[] resources = new ClassPathResource[]
{new ClassPathResource("application.properties"),
new ClassPathResource("application-" + activeProfile + ".properties")};
propertySourcesPlaceholderConfigurer.setLocations(resources);
}
}
Right-click on the package at the Project Panel.
Choose Refactor -> Rename from the context menu.
The answer is, "No."
What C programmers do is store the size of the array somewhere. It can be part of a structure, or the programmer can cheat a bit and malloc()
more memory than requested in order to store a length value before the start of the array.
Serializing data structures containing only numeric or boolean values is fairly straightforward. If you don't have much to serialize, you can write a method for your specific type.
For a Dictionary<int, List<int>>
as you have specified, you can use Linq:
string MyDictionaryToJson(Dictionary<int, List<int>> dict)
{
var entries = dict.Select(d =>
string.Format("\"{0}\": [{1}]", d.Key, string.Join(",", d.Value)));
return "{" + string.Join(",", entries) + "}";
}
But, if you are serializing several different classes, or more complex data structures, or especially if your data contains string values, you would be better off using a reputable JSON library that already knows how to handle things like escape characters and line breaks. Json.NET is a popular option.
instead of using object.getClass().getName()
you can use object.getClass().getSimpleName()
, because it returns a simple class name without a package name included.
for instance,
Object[] intArray = { 1 };
for (Object object : intArray) {
System.out.println(object.getClass().getName());
System.out.println(object.getClass().getSimpleName());
}
gives,
java.lang.Integer
Integer
Python does not have these operators, but if you really need them you can write a function having the same functionality.
def PreIncrement(name, local={}):
#Equivalent to ++name
if name in local:
local[name]+=1
return local[name]
globals()[name]+=1
return globals()[name]
def PostIncrement(name, local={}):
#Equivalent to name++
if name in local:
local[name]+=1
return local[name]-1
globals()[name]+=1
return globals()[name]-1
Usage:
x = 1
y = PreIncrement('x') #y and x are both 2
a = 1
b = PostIncrement('a') #b is 1 and a is 2
Inside a function you have to add locals() as a second argument if you want to change local variable, otherwise it will try to change global.
x = 1
def test():
x = 10
y = PreIncrement('x') #y will be 2, local x will be still 10 and global x will be changed to 2
z = PreIncrement('x', locals()) #z will be 11, local x will be 11 and global x will be unaltered
test()
Also with these functions you can do:
x = 1
print(PreIncrement('x')) #print(x+=1) is illegal!
But in my opinion following approach is much clearer:
x = 1
x+=1
print(x)
Decrement operators:
def PreDecrement(name, local={}):
#Equivalent to --name
if name in local:
local[name]-=1
return local[name]
globals()[name]-=1
return globals()[name]
def PostDecrement(name, local={}):
#Equivalent to name--
if name in local:
local[name]-=1
return local[name]+1
globals()[name]-=1
return globals()[name]+1
I used these functions in my module translating javascript to python.
Any MD5 will produce a good checksum to verify the file. Any of the files listed at the bottom of this page will work fine. http://en.wikipedia.org/wiki/Md5sum
function msort(arr){
for(var i =0;i<arr.length;i++){
for(var j= i+1;j<arr.length;j++){
if(arr[i]>arr[j]){
var swap = arr[i];
arr[i] = arr[j];
arr[j] = swap;
}
}
}
return arr;
}
This is how dynamic languages work. It is not always a good thing though, especially if the documentation is poor - anyone tried to use a poorly documented python framework? Sometimes you have to revert to reading the source.
Here are some strategies to avoid problems with duck typing:
Also, one of the most important points:
There should only be a few well-defined and documented types being passed around. Anything else should be obvious by looking at the code: Don't have weird parameter types coming from far away that you can't figure out by looking in the vicinity of the code...
Related, (and also related to docstrings), there is a technique in python called doctests
. Use that to document how your methods are expected to be used - and have nice unit test coverage at the same time!
I first changed the root password running mysql at a prompt with
mysql -u root -p
Update password:
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
Edited line in the file config.inc.php
with the new root password:
$cfg['Servers'][$i]['password'] = 'MyNewPass'
Stop and re-start mysql service (in Windows: mysql_stop.bat
/mysql_start.bat
)
and got phpMyAdmin to work!
EDIT 2017: for MySQL=5.7 use authentication_string
in place of Password
(see this answer):
UPDATE mysql.user SET authentication_string=PASSWORD('MyNewPass') WHERE User='root';
