Use a timer. There are 3 basic kinds, each suited for different purposes.
Use only in a Windows Form application. This timer is processed as part of the message loop, so the the timer can be frozen under high load.
When you need synchronicity, use this one. This means that the tick event will be run on the thread that started the timer, allowing you to perform GUI operations without much hassle.
This is the most high-powered timer, which fires ticks on a background thread. This lets you perform operations in the background without freezing the GUI or the main thread.
For most cases, I recommend System.Timers.Timer.
If once solved a similar issue by simply checking out a new working copy and replacing the .svn directory throwing the commit errors with this newly checked out one. The reason in my case was that after a repository corruption and restore from a backup the working copy was pointing towards a revision that didn't exist in the restored repository. Also got "item out of date" errors. Updating the working copy before commit didn't solve this but replacing the .svn as described above did.
Try to use:
location.reload(true);
When this method receives a true
value as argument, it will cause the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

You can try to force the soft keyboard to appear, it works for me:
...
dialog.show();
input.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
Update OkHttp 3.0, the getAcceptedIssuers()
function must return an empty array instead of null
.
Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.
You can use -[NSString integerValue]
, -[NSString floatValue]
, etc. However, the correct (locale-sensitive, etc.) way to do this is to use -[NSNumberFormatter numberFromString:]
which will give you an NSNumber converted from the appropriate locale and given the settings of the NSNumberFormatter
(including whether it will allow floating point values).

"Chrome violations" don't represent errors in either Chrome or your own web app. They are instead warnings to help you improve your app. In this case, Long running JavaScript
and took 83ms of runtime
are alerting you there's probably an opportunity to speed up your script.
("Violation" is not the best terminology; it's used here to imply the script "violates" a pre-defined guideline, but "warning" or similar would be clearer. These messages first appeared in Chrome in early 2017 and should ideally have a "More info" prompt to elaborate on the meaning and give suggested actions to the developer. Hopefully those will be added in the future.)
USE this code
function openBackWindow(url,popName){
var popupWindow = window.open(url,popName,'scrollbars=1,height=650,width=1050');
if($.browser.msie){
popupWindow.blur();
window.focus();
}else{
blurPopunder();
}
};
function blurPopunder() {
var winBlankPopup = window.open("about:blank");
if (winBlankPopup) {
winBlankPopup.focus();
winBlankPopup.close()
}
};
IT works fine in Mozilla,IE and chrome on and less than 22 version; but doesn't work in Opera and Safari.
RUn the following query to find if you are running spfile or not:
SELECT DECODE(value, NULL, 'PFILE', 'SPFILE') "Init File Type"
FROM sys.v_$parameter WHERE name = 'spfile';
If the result is "SPFILE", then use the following command:
alter system set open_cursors = 4000 scope=both; --4000 is the number of open cursor
if the result is "PFILE", then use the following command:
alter system set open_cursors = 1000 ;
You can read about SPFILE vs PFILE here,

I would model the DatePicker as an element like textbox / select as shown below.
For the detailed answer - check here- http://www.testautomationguru.com/selenium-webdriver-automating-custom-controls-datepicker/
public class DatePicker {
private static final String dateFormat = "dd MMM yyyy";
@FindBy(css = "a.ui-datepicker-prev")
private WebElement prev;
@FindBy(css = "a.ui-datepicker-next")
private WebElement next;
@FindBy(css = "div.ui-datepicker-title")
private WebElement curDate;
@FindBy(css = "a.ui-state-default")
private List < WebElement > dates;
public void setDate(String date) {
long diff = this.getDateDifferenceInMonths(date);
int day = this.getDay(date);
WebElement arrow = diff >= 0 ? next : prev;
diff = Math.abs(diff);
//click the arrows
for (int i = 0; i < diff; i++)
arrow.click();
//select the date
dates.stream()
.filter(ele - > Integer.parseInt(ele.getText()) == day)
.findFirst()
.ifPresent(ele - > ele.click());
}
private int getDay(String date) {
DateTimeFormatter dtf = DateTimeFormatter.ofPattern(dateFormat);
LocalDate dpToDate = LocalDate.parse(date, dtf);
return dpToDate.getDayOfMonth();
}
private long getDateDifferenceInMonths(String date) {
DateTimeFormatter dtf = DateTimeFormatter.ofPattern(dateFormat);
LocalDate dpCurDate = LocalDate.parse("01 " + this.getCurrentMonthFromDatePicker(), dtf);
LocalDate dpToDate = LocalDate.parse(date, dtf);
return YearMonth.from(dpCurDate).until(dpToDate, ChronoUnit.MONTHS);
}
private String getCurrentMonthFromDatePicker() {
return this.curDate.getText();
}
}
For anyone finding this post through Google (as I did) here's the correct formula for cell F5 in the above example:
=SUMPRODUCT((MONTH(Sheet1!$A$1:$A$50)=MONTH(DATEVALUE(E5&" 1")))*(Sheet1!$A$1:$A$50<>""))
Formula assumes a list of dates in Sheet1!A1:A50 and a month name or abbr ("April" or "Apr") in cell E5.
Combining the two answers:
First create sql to make all index unusable:
alter session set skip_unusable_indexes = true;
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;
Do import...
select 'alter index ' || u.index_name || ' rebuild online;' from user_indexes u;
Once you define a class (MyDTOClass) indicating what you expect to receive it should be as simple as...
public ActionResult Post([FromBody]MyDTOClass inputData){
... do something with input data ...
}

If you're in a Browser-Only environment, use SridharR's solution.
If you're in a Node/CommonJS + Browser environment (e.g. electron, node-webkit, etc..); the reason for this error is that jQuery's export logic first checks for module
, not window
:
if (typeof module === "object" && typeof module.exports === "object") {
// CommonJS/Node
} else {
// window
}
Note that it exports itself via module.exports
in this case; so jQuery
and $
are not assigned to window
.
So to resolve this, instead of <script src="path/to/jquery.js"></script>
;
Simply assign it yourself by a require
statement:
<script>
window.jQuery = window.$ = require('jquery');
</script>
NOTE: If your electron app does not need nodeIntegration
, set it to false
so you won't need this workaround.
The problem with your macro is that once you have opened your destination Workbook (xlw
in your code sample), it is set as the ActiveWorkbook object and you get an error because TextBox1 doesn't exist in that specific Workbook. To resolve this issue, you could define a reference object to your actual Workbook before opening the other one.
Sub UploadData()
Dim xlo As New Excel.Application
Dim xlw As New Excel.Workbook
Dim myWb as Excel.Workbook
Set myWb = ActiveWorkbook
Set xlw = xlo.Workbooks.Open("c:\myworkbook.xlsx")
xlo.Worksheets(1).Cells(2, 1) = myWb.ActiveSheet.Range("d4").Value
xlo.Worksheets(1).Cells(2, 2) = myWb.ActiveSheet.TextBox1.Text
xlw.Save
xlw.Close
Set xlo = Nothing
Set xlw = Nothing
End Sub
If you prefer, you could also use myWb.Activate
to put back your main Workbook as active. It will also work if you do it with a Worksheet object. Using one or another mostly depends on what you want to do (if there are multiple sheets, etc.).
Use val()
to change to the value (not the text) and trigger()
to manually fire the event.
The change event handler must be declared before the trigger.
$('.check').change(function(){
var data= $(this).val();
alert(data);
});
$('.check')
.val('two')
.trigger('change');
DataTable.Select()
doesnt give the Rows in the order they were present in the datatable.
If order is important I feel iterating over the datarow collection and forming a List is the right way to go or you could also use overload of DataTable.Select(string filterexpression, string sort)
.
But this overload may not handle all the ordering (like order by case ...) that SQL provides.

You can redirect STDERR to STDOUT if you want to capture STDERR using backtick.

DECLARE @d char(8)
SET @d = '06082020' /* MMDDYYYY means June 8. 2020 */

Result returned is the original date string in @d as a DateTime.
Each tablespace has one or more datafiles that it uses to store data.
The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.
To find out if the actual limit is 32gb, run the following:
select value from v$parameter where name = 'db_block_size';
Compare the result you get with the first column below, and that will indicate what your max datafile size is.
I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).
Block Sz Max Datafile Sz (Gb) Max DB Sz (Tb)
-------- -------------------- --------------
2,048 8,192 524,264
4,096 16,384 1,048,528
8,192 32,768 2,097,056
16,384 65,536 4,194,112
32,768 131,072 8,388,224
You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):
select bytes/1024/1024 as mb_size,
maxbytes/1024/1024 as maxsize_set,
x.*
from dba_data_files x
MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).
If your datafile has a low max size or autoextend is not on you could simply run:
alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;
However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:
alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;
Simply do this:
<?php
array_push($array, '');
$array = array_reverse($array);
array_shift($array);
A referral is sent by an AD server when it doesn't have the information requested itself, but know that another server have the info. It usually appears in trust environment where a DC can refer to a DC in trusted domain.
In your case you are only specifying a domain, relying on automatic lookup of what domain controller to use. I think that you should try to find out what domain controller is used for the query and look if that one really holds the requested information.
If you provide more information on your AD setup, including any trusts/subdomains, global catalogues and the DNS resource records for the domain controllers it will be easier to help you.
middleware as the name suggests actually middleware is sit between middle.. middle of what? middle of request and response..how request,response,express server sit in express app in this picture you can see requests are coming from client then the express server server serves those requests.. then lets dig deeper.. actually we can divide this whole express server's whole task in to small seperate tasks like in this way. how middleware sit between request and response small chunk of server parts doing some particular task and passed request to next one.. finally doing all the tasks response has been made.. all middle ware can access request object,response object and next function of request response cycle..
this is good example for explaining middleware in express youtube video for middleware

substring()
Methodpublic static String capitalize(String str) {
if(str== null || str.isEmpty()) {
return str;
}
return str.substring(0, 1).toUpperCase() + str.substring(1);
}
Now just call the capitalize()
method to convert the first letter of a string to uppercase:
System.out.println(capitalize("stackoverflow")); // Stackoverflow
System.out.println(capitalize("heLLo")); // HeLLo
System.out.println(capitalize(null)); // null
The StringUtils
class from Commons Lang provides the capitalize()
method that can also be used for this purpose:
System.out.println(StringUtils.capitalize("apache commons")); // Apache commons
System.out.println(StringUtils.capitalize("heLLO")); // HeLLO
System.out.println(StringUtils.uncapitalize(null)); // null
Add the following dependency to your pom.xml
file (for Maven only):
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.9</version>
</dependency>
Here is an article that explains these two approaches in detail.
For those that do know the width, you could do something like
div {

margin-left:auto;
margin-right:auto;

I also agree about not setting text-align:center on the body because it can mess up the rest of your code and you might have to individually set text-align:left on a lot of things either then or in the future.
If are you working with numbers a lot, you might want to take a look at NumPy. It lets you perform all kinds of operation directly on numerical arrays. For example:

>>> array = numpy.array([49, 51, 53, 56])
>>> array - 13
array([36, 38, 40, 43])

Instead of import from Android -> Existing Android Code Into Workspace, You must use General->Existing projects into workspace. It's probably a solution.
Another, free, opensource, Mac OS X v10.8 (Mountain Lion) Preference pane/environment.plist solution is EnvPane.
EnvPane's source code available on GitHub. EnvPane looks like it has comparable features to RCEnvironment, however, it seems it can update its stored variables instantly, i.e. without the need for a restart or login, which is welcome.
As stated by the developer:
EnvPane is a preference pane for Mac OS X 10.8 (Mountain Lion) that lets you set environment variables for all programs in both graphical and terminal sessions. Not only does it restore support for ~/.MacOSX/environment.plist in Mountain Lion, it also publishes your changes to the environment immediately, without the need to log out and back in. <SNIP> EnvPane includes (and automatically installs) a launchd agent that runs 1) early after login and 2) whenever the ~/.MacOSX/environment.plist changes. The agent reads ~/.MacOSX/environment.plist and exports the environment variables from that file to the current user's launchd instance via the same API that is used by launchctl setenv and launchctl unsetenv.
Disclaimer: I am in no way related to the developer or his/her project.
P.S. I like the name (sounds like 'Ends Pain').
The problem is that --exclude="*"
says to exclude (for example) the 1260000000/
directory, so rsync
never examines the contents of that directory, so never notices that the directory contains files that would have been matched by your --include
.
I think the closest thing to what you want is this:
rsync -nrv --include="*/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/
(which will include all directories, and all files matching file_11*.jpg
, but no other files), or maybe this:
rsync -nrv --include="/[0-9][0-9][0-9]0000000/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/
(same concept, but much pickier about the directories it will include).

This syntax is a little more flexible to handle events. Not only can you observe "changes", but also other types of events can be controlled here too by using one single event handler. You can do this by passing the list of events as arguments to the first parameter. See jQuery On
Secondly, .change() is a shortcut for .on( "change", handler ). See here. I prefer using .on() rather than .change because I have more control over the events.
Lastly, I'm simply showing an alternative syntax to attach the event to the element.
why not use:
function getwhatiwant($s)
{
$delimiter='/';
$x=strstr($s,$delimiter,true);
return ($x?$x:$s);
}
OR:
function getwhatiwant($s)
{
$delimiter='/';
$t=explode($delimiter, $s);
return ($t[1]?$t[0]:$s);
}

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.
You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,
http://www.javaworld.com/javaworld/javatips/jw-javatip111.html
EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,
public SSLTunnelSocketFactory(String proxyhost, String proxyport){
tunnelHost = proxyhost;
tunnelPort = Integer.parseInt(proxyport);
dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
}
...
connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
connection.setDefaultHostnameVerifier( new HostnameVerifier()
{
public boolean verify( String arg0, SSLSession arg1 )
{
return true;
}
} );
EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,
http://bugs.sun.com/view_bug.do?bug_id=6614957
The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,
public class SSLContextTest {
public static void main(String[] args) {
System.setProperty("https.proxyHost", "proxy.xxx.com");
System.setProperty("https.proxyPort", "8888");
try {
SSLContext sslContext = SSLContext.getInstance("SSL");
// set up a TrustManager that trusts everything
sslContext.init(null, new TrustManager[] { new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
System.out.println("getAcceptedIssuers =============");
return null;
}
public void checkClientTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkClientTrusted =============");
}
public void checkServerTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkServerTrusted =============");
}
} }, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(
sslContext.getSocketFactory());
HttpsURLConnection
.setDefaultHostnameVerifier(new HostnameVerifier() {
public boolean verify(String arg0, SSLSession arg1) {
System.out.println("hostnameVerifier =============");
return true;
}
});
URL url = new URL("https://www.verisign.net");
URLConnection conn = url.openConnection();
BufferedReader reader =
new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
This is what I get when I run the program,
checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......
As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.
All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.
We first set the arrays:
$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);
Then we add them to the new array :
$newArr[] = $arr1;
$newArr[] = $arr2;
Now lets see our new array with all the keys:
print_r($newArr);
There's no need for sql or special functions to build a new multi-dimensional array.... don't use a tank to get to where you can walk.
Here's a dimensionality-independent standalone solution.
This will convert any N-dimensional array arr
of nonnegative integers to a one-hot N+1-dimensional array one_hot
, where one_hot[i_1,...,i_N,c] = 1
means arr[i_1,...,i_N] = c
. You can recover the input via np.argmax(one_hot, -1)
def expand_integer_grid(arr, n_classes):
"""
:param arr: N dim array of size i_1, ..., i_N
:param n_classes: C
:returns: one-hot N+1 dim array of size i_1, ..., i_N, C
:rtype: ndarray
"""
one_hot = np.zeros(arr.shape + (n_classes,))
axes_ranges = [range(arr.shape[i]) for i in range(arr.ndim)]
flat_grids = [_.ravel() for _ in np.meshgrid(*axes_ranges, indexing='ij')]
one_hot[flat_grids + [arr.ravel()]] = 1
assert((one_hot.sum(-1) == 1).all())
assert(np.allclose(np.argmax(one_hot, -1), arr))
return one_hot
I believe you'd want to escape by doubling the single quote:
INSERT INTO table_name (field1, field2) VALUES (123, 'Hello there''s');
The brackets are required if you use keywords or special chars in the column names or identifiers. You could name a column [First Name]
(with a space)--but then you'd need to use brackets every time you referred to that column.
The newer tools add them everywhere just in case or for consistency.
Try using
$(window).unload(function(){
localStorage.clear();
});
Hope this works for you
In this case no conditionals are needed to set the variable.
This one-liner XPath expression:
boolean(joined-subclass)
is true()
only when the child of the current node, named joined-subclass
exists and it is false()
otherwise.
The complete stylesheet is:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="class">
<xsl:variable name="subexists"
select="boolean(joined-subclass)"
/>
subexists: <xsl:text/>
<xsl:value-of select="$subexists" />
</xsl:template>
</xsl:stylesheet>
Do note, that the use of the XPath function boolean()
in this expression is to convert a node (or its absense) to one of the boolean values true()
or false()
.
This is how I do it:
>>> import traceback
>>> try:
... int('k')
... except:
... var = traceback.format_exc()
...
>>> print var
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ValueError: invalid literal for int() with base 10: 'k'
You should however take a look at the traceback documentation, as you might find there more suitable methods, depending to how you want to process your variable afterwards...
To add a unique key use :
alter table your_table add UNIQUE(target_column_name);
To remove a unique key use:
alter table your_table drop INDEX target_column_name;
in angular projects we add angular-cli.json or angular.json theses lines:
"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/bootstrap/dist/js/bootstrap.min.js"
],
The easiest solution I found for this so far is the Non-Sucking Service Manager
Usage would be
nssm install <servicename> "C:\Program Files\Java\jre7\java.exe" "-jar <path-to-jar-file>"
Use python's csv
module for reading and writing comma or tab-delimited files. The csv module is preferred because it gives you good control over quoting.
For example, here is the worked example for you:
import csv
data = ["value %d" % i for i in range(1,4)]
out = csv.writer(open("myfile.csv","w"), delimiter=',',quoting=csv.QUOTE_ALL)
out.writerow(data)
Produces:
"value 1","value 2","value 3"
NB. Constructor function names should start with a capital letter to distinguish them from ordinary functions, e.g. MyClass
instead of myClass
.
Either you can call init
from your constructor function:
var myObj = new MyClass(2, true);
function MyClass(v1, v2)
{
// ...
// pub methods
this.init = function() {
// do some stuff
};
// ...
this.init(); // <------------ added this
}
Or more simply you could just copy the body of the init
function to the end of the constructor function. No need to actually have an init
function at all if it's only called once.
In IIS >= 7, a <webLimits>
section has replaced ConnectionTimeout
, HeaderWaitTimeout
, MaxGlobalBandwidth
, and MinFileBytesPerSec
IIS 6 metabase settings.
Example Configuration:
<configuration>
<system.applicationHost>
<webLimits connectionTimeout="00:01:00"
dynamicIdleThreshold="150"
headerWaitTimeout="00:00:30"
minBytesPerSecond="500"
/>
</system.applicationHost>
</configuration>
For reference: more information regarding these settings in IIS can be found here. Also, I was unable to add this section to the web.config via the IIS manager's "configuration editor", though it did show up once I added it and searched the configuration.
This happens because $cOTLdata
is not null but the index 'char_data'
does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.
To check whether the index exists or not you can use isset():
isset($cOTLdata['char_data'])
Which means the line should look something like this:
$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;
Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

To actually cover your pattern, i.e, valid file names according to your rules, I think that you need a little more. Note this doesn't match legal file names from a system perspective. That would be system dependent and more liberal in what it accepts. This is intended to match your acceptable patterns.
^([a-zA-Z0-9]+[_-])*[a-zA-Z0-9]+\.[a-zA-Z0-9]+$
Explanation:
^
Match the start of a string. This (plus the end match) forces the string to conform to the exact expression, not merely contain a substring matching the expression.([a-zA-Z0-9]+[_-])*
Zero or more occurrences of one or more letters or numbers followed by an underscore or dash. This causes all names that contain a dash or underscore to have letters or numbers between them.[a-zA-Z0-9]+
One or more letters or numbers. This covers all names that do not contain an underscore or a dash.\.
A literal period (dot). Forces the file name to have an extension and, by exclusion from the rest of the pattern, only allow the period to be used between the name and the extension. If you want more than one extension that could be handled as well using the same technique as for the dash/underscore, just at the end.[a-zA-Z0-9]+
One or more letters or numbers. The extension must be at least one character long and must contain only letters and numbers. This is typical, but if you wanted allow underscores, that could be addressed as well. You could also supply a length range {2,3}
instead of the one or more +
matcher, if that were more appropriate.$
Match the end of the string. See the starting character.Assuming your dataframe is mydf:
mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))
The existing answers already cover the "how", but I just wanted to elaborate on the "what" and "why" for others who might be wondering.
What a compiler (gcc) does: The term "compile" is a bit of an overloaded term because it is used at a high-level to mean "convert source code to a program", but more technically means to "convert source code to object code". A compiler like gcc actually performs two related, but arguably distinct functions to turn your source code into a program: compiling (as in the latter definition of turning source to object code) and linking (the process of combining the necessary object code files together into one complete executable).
The original error that you saw is technically a "linking error", and is thrown by "ld", the linker. Unlike (strict) compile-time errors, there is no reference to source code lines, as the linker is already in object space.
By default, when gcc is given source code as input, it attempts to compile each and then link them all together. As noted in the other responses, it's possible to use flags to instruct gcc to just compile first, then use the object files later to link in a separate step. This two-step process may seem unnecessary (and probably is for very small programs) but it is very important when managing a very large program, where compiling the entire project each time you make a small change would waste a considerable amount of time.
Here is how to wait in Selenium for a condition:
WebDriverWait wait = new WebDriverWait(m_driver, TimeSpan.FromSeconds(10));
wait.Until(d => ReadCell(row, col) != "");
ReadCell(row, col) != ""
can be any condition. Like this way because:
public static void Serialize(object value, Stream s)
{
using (StreamWriter writer = new StreamWriter(s))
using (JsonTextWriter jsonWriter = new JsonTextWriter(writer))
{
JsonSerializer ser = new JsonSerializer();
ser.Serialize(jsonWriter, value);
jsonWriter.Flush();
}
}
public static T Deserialize<T>(Stream s)
{
using (StreamReader reader = new StreamReader(s))
using (JsonTextReader jsonReader = new JsonTextReader(reader))
{
JsonSerializer ser = new JsonSerializer();
return ser.Deserialize<T>(jsonReader);
}
}
Linking to local resources is disabled in all modern browsers due to security restrictions.
For Firefox:
For security purposes, Mozilla applications block links to local files (and directories) from remote files. This includes linking to files on your hard drive, on mapped network drives, and accessible via Uniform Naming Convention (UNC) paths. This prevents a number of unpleasant possibilities, including:
- Allowing sites to detect your operating system by checking default installation paths
- Allowing sites to exploit system vulnerabilities (e.g., C:\con\con in Windows 95/98)
- Allowing sites to detect browser preferences or read sensitive data
for IE:
Internet Explorer 6 Service Pack 1 (SP1) no longer allows browsing a local machine from the Internet zone. For instance, if an Internet site contains a link to a local file, Internet Explorer 6 SP1 displays a blank page when a user clicks on the link. Previous versions of Windows Internet Explorer followed the link to the local file.
for Opera (in the context of a security advisory, I'm sure there is a more canonical link for this):
As a security precaution, Opera does not allow Web pages to link to files on the user's local disk
Using value={whatever}
will make it so you cannot type in the input field. You should use defaultValue="Hello!"
.
See https://facebook.github.io/react/docs/uncontrolled-components.html#default-values
Also, the onchange
should be onChange
as @davnicwil points out.
Either use:
pip install xlrd
And if you are using conda, use
conda install -c anaconda xlrd
That's it. good luck.
If you want to convert to the new ES6 Map do this:
var kvArray = [['key1', 'value1'], ['key2', 'value2']];
var myMap = new Map(kvArray);
Why should you use this type of Map? Well that is up to you. Take a look at this.
If you want to add REM at the beginning of each line instead of using GOTO, you can use Notepad++ to do this easily following these steps:
Repeat steps to uncomment
You can use exit method to quit an ios app :
exit(0);
You should say same alert message and ask him to quit
Another way is by using [[NSThread mainThread] exit]
However you should not do this way
According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.
This means your nested SELECT returns more than one rows.
You need to add a proper WHERE clause to it.
Vinay is correct. In answer to your comment in his answer, one way you can do it is as follows:
<root>
<level value="ALL" />
<appender-ref ref="File1Appender" />
</root>
<logger name="SomeName">
<level value="ALL" />
<appender-ref ref="File1Appender2" />
</logger>
This is how I have done it in the past. Then something like this for the other log:
private static readonly ILog otherLog = LogManager.GetLogger("SomeName");
And you can get your normal logger as follows:
private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
Read the loggers and appenders section of the documentation to understand how this works.
In my case I had to include several additional exclusions. It appears it doesn't like Regular expressions which would've made this a nice one-liner.
android {
packagingOptions {
exclude 'META-INF/DEPENDENCIES.txt'
exclude 'META-INF/DEPENDENCIES'
exclude 'META-INF/dependencies.txt'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/LICENSE'
exclude 'META-INF/license.txt'
exclude 'META-INF/LGPL2.1'
exclude 'META-INF/NOTICE.txt'
exclude 'META-INF/NOTICE'
exclude 'META-INF/notice.txt'
}
}
You need quotes around the string you're trying to pass off as a date, and you can also use BETWEEN here:
SELECT *
FROM TABLENAME
WHERE DateTime BETWEEN '04/12/2011 12:00:00 AM' AND '05/25/2011 3:53:04 AM'
See answer to the following question for examples on how to explicitly convert strings to dates while specifying the format:
The first solution is to use the java.util.Random
class:
import java.util.Random;
Random rand = new Random();
// Obtain a number between [0 - 49].
int n = rand.nextInt(50);
// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;
Another solution is using Math.random()
:
double random = Math.random() * 49 + 1;
or
int random = (int)(Math.random() * 50 + 1);
x if y else z
is the syntax for the expression you're returning for each element. Thus you need:
[ x if x%2 else x*100 for x in range(1, 10) ]
The confusion arises from the fact you're using a filter in the first example, but not in the second. In the second example you're only mapping each value to another, using a ternary-operator expression.
With a filter, you need:
[ EXP for x in seq if COND ]
Without a filter you need:
[ EXP for x in seq ]
and in your second example, the expression is a "complex" one, which happens to involve an if-else
.
You can use the below code on your string and you will get the complete string without html part.
string title = "<b> Hulk Hogan's Celebrity Championship Wrestling <font color=\"#228b22\">[Proj # 206010]</font></b> (Reality Series, )".Replace(" ",string.Empty);
string s = Regex.Replace(title, "<.*?>", String.Empty);
How about
if (length ($name || '')) {
# do something with $name
}
This isn't quite equivalent to your original version, as it will also return false if $name
is the numeric value 0 or the string '0'
, but will behave the same in all other cases.
In perl 5.10 (or later), the appropriate approach would be to use the defined-or operator instead:
use feature ':5.10';
if (length ($name // '')) {
# do something with $name
}
This will decide what to get the length of based on whether $name
is defined, rather than whether it's true, so 0/'0'
will handle those cases correctly, but it requires a more recent version of perl than many people have available.
Close your project, and then import project. That work for me. It's a simply way.
good luck.
var count=0;
let myArray = '{"1":"a","2":"b","3":"c","4":"d"}'
var data = JSON.parse(myArray);
for (let key in data) {
let value = data[key]; // get the value by key
console.log("key: , value:", key, value);
count = count + 1;
}
console.log("size:",count);
I just type following keywords in the opened terminal;
See details in the below image. (VSCode version 1.19.1 - windows 10 OS)
It works on VS Code Mac as well. I tried it with VSCode (Version 1.20.1)
$recipients = "Marcel <[email protected]>, Marcelt <[email protected]>"
is type of string
you need pass to send-mailmessage
a string[]
type (an array):
[string[]]$recipients = "Marcel <[email protected]>", "Marcelt <[email protected]>"
I think that not casting to string[] do the job for the coercing rules of powershell:
$recipients = "Marcel <[email protected]>", "Marcelt <[email protected]>"
is object[]
type but can do the same job.
A static method can NOT access a Non-static method or variable.
public static void main(String[] args)
is a static method, so can NOT access the Non-static public static int fxn(int y)
method.
Try it this way...
static int fxn(int y)
public class Two {
public static void main(String[] args) {
int x = 0;
System.out.println("x = " + x);
x = fxn(x);
System.out.println("x = " + x);
}
static int fxn(int y) {
y = 5;
return y;
}
}

Simply install Win64 OpenSSL v1.0.2a or Win32 OpenSSL v1.0.2a, you can download these from http://slproweb.com/products/Win32OpenSSL.html. Works out of the box, no configuration needed.
Hello you can make use of input and output. Input let you to pass variable form parent to child. Output the same but from child to parent.
The easiest way is to pass "startdate" and "endDate" as input
<calendar [startDateInCalendar]="startDateInSearch" [endDateInCalendar]="endDateInSearch" ></calendar>
In this way you have your startdate and enddate directly in search page. Let me know if it works, or think another way. Thanks
Using the correct drawable subfolder solved it for me. My solution was to put my full resolution image (1920x1200) into the drawable-xhdpi folder, instead of the drawable folder.
I also put a scaled down image (1280x800) into the drawable-hdpi folder.
These two resolutions match the 2013 and 2012 Nexus 7 tablets I'm programming. I also tested the solution on some other tablets.
I don't know what version of CI you were using back in 2013, but I am using CI3 and I just tested with two null
parameters passed to limit()
and there was no LIMIT
or OFFSET
in the rendered query (I checked by using get_compiled_select()
).
This means that -- assuming your have correctly posted your coding attempt -- you don't need to change anything (or at least the old issue is no longer a CI issue).
If this was my project, this is how I would write the method to return an indexed array of objects or an empty array if there are no qualifying rows in the result set.
function nationList($limit = null, $start = null) {
// assuming the language value is sanitized/validated/whitelisted
return $this->db
->select('nation.id, nation.name_' . $this->session->userdata('language') . ' AS name')
->from('nation')
->order_by("name")
->limit($limit, $start)
->get()
->result();
}
These refinements remove unnecessary syntax, conditions, and the redundant loop.
For reference, here is the CI core code:
/**
* LIMIT
*
* @param int $value LIMIT value
* @param int $offset OFFSET value
* @return CI_DB_query_builder
*/
public function limit($value, $offset = 0)
{
is_null($value) OR $this->qb_limit = (int) $value;
empty($offset) OR $this->qb_offset = (int) $offset;
return $this;
}
So the $this->qb_limit
and $this->qb_offset
class objects are not updated because null
evaluates as true
when fed to is_null()
or empty()
.

Images -
The file system and configuration(read-only) application which is used to create containers. More detail.
Containers -
The major difference between a container and an image is the top writable layer. Containers are running instances of Docker images with top writable layer. Containers run the actual applications. A container includes an application and all of its dependencies. When the container is deleted, the writable layer is also deleted. The underlying image remains unchanged. More detail.
Other important terms to notice:
Docker daemon -
The background service running on the host that manages the building, running and distributing Docker containers.
Docker client -
The command line tool that allows the user to interact with the Docker daemon.
Docker Store -
Store is, among other things, a registry of Docker images. You can think of the registry as a directory of all available Docker images.
A picture from this blog post is worth a thousand words.
(For deeper understanding please read this.)
Summary:
docker run image_name:tag_name
) => Gives a running Image i.e. container (editable)Console.Read() takes a character and returns the ascii value of that character.So if you want to take the symbol that was entered by the user instead of its ascii value (ex:if input is 5 then symbol = 5, ascii value is 53), you have to parse it using int.parse() but it raises a compilation error because the return value of Console.Read() is already int type. So you can get the work done by using Console.ReadLine() instead of Console.Read() as follows.
int userInput = int.parse(Console.ReadLine());
here, the output of the Console.ReadLine() would be a string containing a number such as "53".By passing it to the int.Parse() we can convert it to int type.
http://www.pip-installer.org/en/latest/installing.html is really the canonical answer to this question.
Specifically, the systemwide instructions are:
$ curl -O http://python-distribute.org/distribute_setup.py
$ python distribute_setup.py
$ curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
$ python get-pip.py
The section quoted in the question is the virtualenv
instructions rather than the systemwide ones. The easy_install
instructions have been around for longer, but it isn't necessary to do it that way any more.
I am not sure how to see the actual rows/records that come back.
Stored procedures do not return records. They may have a cursor as an output parameter, which is a pointer to a select statement. But it requires additional action to actually bring back rows from that cursor.
In SQL Developer, you can execute a procedure that returns a ref cursor as follows
var rc refcursor
exec proc_name(:rc)
After that, if you execute the following, it will show the results from the cursor:
print rc
You can create a global method to show message(alert) in your web form application.

You just have to put it under separate folders with different names depending on orientation and resolution, the device will automatically select the right one for its screen settings
More info here:

under "Resource directory qualifiers for screen size and density"
if you don't or cannot go through cursor and if you have only paths or File objects, you can use since API level 8 (2.2) public static Bitmap createVideoThumbnail (String filePath, int kind)
The following code runs perfectly:
Bitmap bMap = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MICRO_KIND);
$unit1 = "paragrahp1";
$unit2 = "paragrahp2";
echo '<p>'.$unit1.'</p>';
echo '<p>'.$unit2.'</p>';
Use Tag <p>
always when starting with a new line so you don't need to use /n type syntax.

I just finished a rewrite with useReducer, following @kentcdobs article (ref below) which really gave me a solid result that suffers not one bit from these closure problems.
see: https://kentcdodds.com/blog/how-to-use-react-context-effectively
I condensed his readable boilerplate to my preferred level of DRYness -- reading his sandbox implementation will show you how it actually works.
Enjoy, I know I am !!

export const AltIdPage = () => {
const history = useHistory();
const [keyCode, setKeyCode] = useKeyCode();
const [phoneNumber, setPhoneNumber] = usePhoneNumber();
const [appConfig, setAppConfig] = useAppConfig();
const keyPressed = btn => {
const maxLen = appConfig.phoneNumberEntry.entryLen;
const newValue = HandleKeyPress(btn, phoneNumber).slice(0, maxLen);
setPhoneNumber(newValue);
}
const doSubmit = () => {
history.push('s');
}
const disableBtns = phoneNumber.length < appConfig.phoneNumberEntry.entryLen;
return (
<Container fluid className="text-center">
<Row>
<Messaging {...{ msgColors: appConfig.pageColors, msgLines: appConfig.entryMsgs.altIdMsgs }} />
</Row>

);
};
AltIdPage.propTypes = {};
Now everything persists smoothly everywhere across all my pages

If you want to pass a JavaScript object/hash (ie. an associative array in PHP) then you would do:
$.post('/url/to/page', {'key1': 'value', 'key2': 'value'});
If you wanna pass an actual array (ie. an indexed array in PHP) then you can do:
$.post('/url/to/page', {'someKeyName': ['value','value']});
If you want to pass a JavaScript array then you can do:
$.post('/url/to/page', {'someKeyName': variableName});
Generic Syntax :
$git diff oldCommit..newCommit -- **FileName.xml > ~/diff.txt
for all files named "FileName.xml" anywhere in your repo.
Notice the space between "--" and "**"
Answer for your question:
$git checkout master
$git diff oldCommit..HEAD -- **pom.xml
or
$git diff oldCommit..HEAD -- relative/path/to/pom.xml
as always with git, you can use a tag/sha1/"HEAD^" to id a commit.
Tested with git 1.9.1 on Ubuntu.
You can use PHP to add a stylesheet for IE 10
Like:
if (stripos($_SERVER['HTTP_USER_AGENT'], 'MSIE 10')) {
<link rel="stylesheet" type="text/css" href="../ie10.css" />
}
// Parent layout
LinearLayout parentLayout = (LinearLayout)findViewById(R.id.layout);
// Layout inflater
LayoutInflater layoutInflater = getLayoutInflater();
View view;
for (int i = 1; i < 101; i++){
// Add the text layout to the parent layout
view = layoutInflater.inflate(R.layout.text_layout, parentLayout, false);
// In order to get the view we have to use the new view with text_layout in it
TextView textView = (TextView)view.findViewById(R.id.text);
textView.setText("Row " + i);
// Add the text view to the parent layout
parentLayout.addView(textView);
}
Saudate, I ran across this looking for a different problem. You most definitely can use the Sql Server Import wizard to import data into a new table. Of course, you do not wish to leave that table in the database, so my suggesting is that you import into a new table, then script the data in query manager to insert into the existing table. You can add a line to drop the temp table created by the import wizard as the last step upon successful completion of the script.
I believe your original issue is in fact related to Sql Server 64 bit and is due to your having a 32 bit Excel and these drivers don't play well together. I did run into a very similar issue when first using 64 bit excel.
Note that the performance of Enum.Parse()
is awful, because it is implemented via reflection. (The same is true of Enum.ToString
, which goes the other way.)
If you need to convert strings to Enums in performance-sensitive code, your best bet is to create a Dictionary<String,YourEnum>
at startup and use that to do your conversions.
Use:
AND oh.tran_date BETWEEN TRUNC(SYSDATE - 1) AND TRUNC(SYSDATE) - 1/86400
Reference: TRUNC
Calling a function on the tran_date
means the optimizer won't be able to use an index (assuming one exists) associated with it. Some databases, such as Oracle, support function based indexes which allow for performing functions on the data to minimize impact in such situations, but IME DBAs won't allow these. And I agree - they aren't really necessary in this instance.
You can launch the shutdown process:
shutdown -s -t 0
- Shutdownshutdown -r -t 0
- RestartYou can do it like this:
var mongoose = require('mongoose');
var _id = mongoose.mongo.BSONPure.ObjectID.fromHexString("4eb6e7e7e9b7f4194e000001");
EDIT: New standard has fromHexString rather than fromString
You can't use forward declaration with the typedef struct
.
The struct
itself is an anonymous type, so you don't have an actual name to forward declare.
typedef struct{
int one;
int two;
} myStruct;
A forward declaration like this won't work:
struct myStruct; //forward declaration fails
void blah(myStruct* pStruct);
//error C2371: 'myStruct' : redefinition; different basic types
A way to future proof and/or prevent overwriting of existing prototype would be test check to see if it has already been added to the String prototype. Here's my take on the non-regex highly rated version.
if (typeof String.endsWith !== 'function') {
String.prototype.endsWith = function (suffix) {
return this.indexOf(suffix, this.length - suffix.length) !== -1;
};
}
In a case
statement, a ,
is the equivalent of ||
in an if
statement.
case car
when 'toyota', 'lexus'
# code
end
Get-Content
(alias: gc
) is your usual option for reading a text file. You can then filter further:
gc log.txt | select -first 10 # head
gc -TotalCount 10 log.txt # also head
gc log.txt | select -last 10 # tail
gc -Tail 10 log.txt # also tail (since PSv3), also much faster than above option
gc log.txt | more # or less if you have it installed
gc log.txt | %{ $_ -replace '\d+', '($0)' } # sed
This works well enough for small files, larger ones (more than a few MiB) are probably a bit slow.
The PowerShell Community Extensions include some cmdlets for specialised file stuff (e.g. Get-FileTail).
For Angular you should simply use formatDate
instead of the DatePipe
.
import {formatDate} from '@angular/common';
constructor(@Inject(LOCALE_ID) private locale: string) {
this.dateString = formatDate(Date.now(),'yyyy-MM-dd',this.locale);
}
For Windows Environments:
If you don't want to go to the command prompt (or work in an environment where command prompt is restricted), I think the following solution is better than inserting code into python that asks you to press any key - because if the program crashes before it reaches that point, the window closes and you lose the crash info. The solution I use is to create a bat file.
Use notepad to create a text file. In the file the contents will look something like:
my_python_program.py
pause
Then save the file as "my_python_program.bat"
When you run the bat file it will run the python program and pause at the end to allow you to read the output. Then if you press any key it will close the window.
I always used APC with php 5.1 and 5.2, but I had a lot of (random) errors using APC with php 5.3: Strange blank pages, random out-of-memory errors. They all disappeared when I disabled APC. But that was no option, as it is running a high-volume website.
So I tried eaccelerator. So far it has been rock solid and the speed increase is even bigger than with APC. The APC guys really need to spend some time on bugfixing.
I got same problem but different reason. I had "reg.bat" in the current directory. Renaming that into anything else solved the issue.
With PowerShell 5.1 in Windows 10 you can use:
Get-SmbMapping | Remove-SmbMapping -Confirm:$false

HashMap<String, Integer> hm = new HashMap<>();

int Count = 0;

Count++;
}
}
hm.put(S3[i], Count);
}
System.out.println("Duplicate Words and their number of occurrences in String S1 : " + hm);
}
}
i'll make an example,
first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit)
, and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),
setting up the netcat server to listen on port 9999: nc -l 9999
now hitting http://127.0.0.1:9999 in firefox, i get:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1
now let us compare that with this simple script:
<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);
i get:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*
there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent
specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding
header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:
<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
CURLOPT_ENCODING=>'gzip, deflate',
CURLOPT_HTTPHEADER=>array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: en-US,en;q=0.5',
'Connection: keep-alive',
'Upgrade-Insecure-Requests: 1',
),
));
curl_exec($ch);
now running that code, our netcat server gets:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1
and voila! our php-emulated browser
GET request should now be indistinguishable from the real firefox GET request :)
this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding
header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,
<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
CURLOPT_ENCODING=>'gzip, deflate',
CURLOPT_HTTPHEADER=>array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Language: en-US,en;q=0.5',
'Accept-Encoding: gzip, deflate',
'Connection: keep-alive',
'Upgrade-Insecure-Requests: 1',
),
));
curl_exec($ch);
running that, our netcat server gets:
$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1
problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

didn't work for me as it kept firing for every EditText
and messing up each others values.
Here is my solution:
public class ConsultantTSView extends Activity {
.....
//Submit is called when I push submit button.
//I wanted to retrieve all EditText(tsHours) values in my HoursList
public void submit(View view){
ListView TSDateListView = (ListView) findViewById(R.id.hoursList);
String value = ((EditText) TSDateListView.getChildAt(0).findViewById(R.id.tsHours)).getText().toString();
}
}
Hence by using the getChildAt(xx)
method you can retrieve any item in the ListView
and get the individual item using findViewById
. And it will then give the most recent value.
Its just like creating a WAR
file of your project, you can do it in several ways (from Eclipse, command line, maven).
If you want to do from command line, the command is
jar -cvf my_web_app.war *
Which means, "compress everything in this directory into a file named my_web_app.war" (c=create, v=verbose, f=file)
In my case, I had a condition when the user click the "a" element. The condition was:
If other section had more than ten items, then the user should be not redirected to other page.
If other section had less than ten items, then the user should be redirected to other page.
The functionality of the "a" elements depends of the other component. The code within click event is the follow:
var elementsOtherSection = document.querySelectorAll("#vehicle-item").length;
if (elementsOtherSection> 10){
return true;
}else{
event.preventDefault();
return false;
}
$apply
should be called?TL;DR:
$apply
should be called whenever you want to apply changes made outside of Angular world.
Just to update @Dustin's answer, here is an explanation of what $apply exactly does and why it works.
$apply()
is used to execute an expression in AngularJS from outside of the AngularJS framework. (For example from browser DOM events, setTimeout, XHR or third party libraries). Because we are calling into the AngularJS framework we need to perform proper scope life cycle of exception handling, executing watches.
Angular allows any value to be used as a binding target. Then at the end of any JavaScript code turn, it checks to see if the value has changed.
That step that checks to see if any binding values have changed actually has a method, $scope.$digest()
1. We almost never call it directly, as we use $scope.$apply()
instead (which will call $scope.$digest
).
Angular only monitors variables used in expressions and anything inside of a $watch
living inside the scope. So if you are changing the model outside of the Angular context, you will need to call $scope.$apply()
for those changes to be propagated, otherwise Angular will not know that they have been changed thus the binding will not be updated2.
using sqldf
fits here:
library(sqldf)
sqldf("SELECT Believe, Count(1) as N FROM Santa
GROUP BY Believe")
use javascript inbuild functions escape and unescape
for example
var escapedData = escape("hel'lo");
output = "%27hel%27lo%27" which can be used in the attribute.
again to read the value from the attr
var unescapedData = unescape("%27hel%27lo%27")
output = "'hel'lo'"
This will be helpful if you have huge json stringify data to be used in the attribute
Setting the -fx-text-fill
works for me.
See below:
if (passed) {
resultInfo.setText("Passed!");
resultInfo.setStyle("-fx-text-fill: green; -fx-font-size: 16px;");
} else {
resultInfo.setText("Failed!");
resultInfo.setStyle("-fx-text-fill: red; -fx-font-size: 16px;");
}
I ran into this problem today and I needed it on Solaris so here is a POSIX standard way to do (something very close to) this.
#Detect OS
UNAME = `uname`
# Build based on OS name
DetectOS:
-@make $(UNAME)
# OS is Linux, use GCC
Linux: program.c
@SHELL_VARIABLE="-D_LINUX_STUFF_HERE_"
rm -f program
gcc $(SHELL_VARIABLE) -o program program.c
# OS is Solaris, use c99
SunOS: program.c
@SHELL_VARIABLE="-D_SOLARIS_STUFF_HERE_"
rm -f program
c99 $(SHELL_VARIABLE) -o program program.c
I had this problem. I searched the internet, took all advices, changes configurations, but the problem is still there. Finally with the help of the server administrator, he found that the problem lies in MySQL database column definition. one of the columns in the a table was assigned to 'Longtext' which leads to allocate 4,294,967,295 bites of memory. It seems working OK if you don't use MySqli prepare statement, but once you use prepare statement, it tries to allocate that amount of memory. I changed the column type to Mediumtext which needs 16,777,215 bites of memory space. The problem is gone. Hope this help.
You can very easily override the val
function to trigger change by replacing it with a proxy to the original val
function.
just add This code somewhere in your document (after loading jQuery)
(function($){
var originalVal = $.fn.val;
$.fn.val = function(){
var result =originalVal.apply(this,arguments);
if(arguments.length>0)
$(this).change(); // OR with custom event $(this).trigger('value-changed');
return result;
};
})(jQuery);
A working example: here
(Note that this will always trigger change
when val(new_val)
is called even if the value didn't actually changed.)
If you want to trigger change ONLY when the value actually changed, use this one:
//This will trigger "change" event when "val(new_val)" called
//with value different than the current one
(function($){
var originalVal = $.fn.val;
$.fn.val = function(){
var prev;
if(arguments.length>0){
prev = originalVal.apply(this,[]);
}
var result =originalVal.apply(this,arguments);
if(arguments.length>0 && prev!=originalVal.apply(this,[]))
$(this).change(); // OR with custom event $(this).trigger('value-changed')
return result;
};
})(jQuery);
Live example for that: http://jsfiddle.net/5fSmx/1/
I was having trouble with a local DB.
I was able to solve this problem by stopping SQL server, and then starting SQL server, and then using the SSMS UI to change the DB properties to Multi_User.
The DB went into "Single User" Mode when i was attempting to restore a backup. I hadn't created a backup of the target database before attempting to restore (SQL 2017). this will get you every time.
Stop SQL Server, Start SQL Server, then run the above Scripts or use the UI.
To add rows to existing DataTable in Dataset:
DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);
In the default constructor (and any non-default ones if you have any too of course):
public foo() {
Bar = "bar";
}
This is no less performant that your original code I believe, since this is what happens behind the scenes anyway.
You can also use npmlog by issacs, recommended in https://npmjs.org/doc/coding-style.html.
You can find this module here https://github.com/isaacs/npmlog
I had the same problem but I solved it differently. I don't know if it's a good way of doing it, but it works great for what I need.
I used @Inject on the constructor of the child component, like this:
import { Component, OnInit, Inject } from '@angular/core';
import { ParentComponent } from '../views/parent/parent.component';
export class ChildComponent{
constructor(@Inject(ParentComponent) private parent: ParentComponent){
}
someMethod(){
this.parent.aPublicProperty = 2;
}
}
This worked for me, you only need to declare the method or property you want to call as public.
In my case, the AppComponent handles the routing, and I'm using badges in the menu items to alert the user that new unread messages are available. So everytime a user reads a message, I want that counter to refresh, so I call the refresh method so that the number at the menu nav gets updated with the new value. This is probably not the best way but I like it for its simplicity.
python 2.7
import pymysql
conn = pymysql.connect(host='localhost', port=3306, user='root', passwd='password', db='sakila')

c = cur.fetchall()
for i in c:

To add to the excellent list (given by @CodeCowboyOrg) of situations where OPTION(RECOMPILE) can be very helpful,
Another approach is by using regular expressions.
$fileName = basename($filePath);
$fileNameNoExtension = preg_replace("/\.[^.]+$/", "", $fileName);
This removes from the last period .
up until the end of the string.
You can always press CTRL-B + SHIFT-D to choose which client you want to detach from the session.
tmux will list all sessions with their current dimension. Then you simply detach from all the smaller sized sessions.
Your code works fine.
def list = [["c":"d"], ["e":"f"], ["g":"h"]]
Map tmpHM = [1:"second (e:f)", 0:"first (c:d)", 2:"third (g:h)"]
for (objKey in tmpHM.keySet()) {
HashMap objHM = (HashMap) list.get(objKey);
print("objHM: ${objHM} , ")
}
prints objHM: [e:f] , objHM: [c:d] , objHM: [g:h] ,

Then click "edit in console", "execute script"
If I understand your question correctly, I've made a fiddle that has this working correctly. This issue is with how you're assigning the event handlers and as others have said you have over riding event handlers. The current jQuery best practice is to use on()
to register event handlers. Here's a link to the jQuery docs about on
: link
Your original solution was pretty close but the way you added the event handlers is a bit confusing. It's considered best practice to not add events to HTML elements. I recommend reading up on Unobstrusive JavaScript.
Here's the JavaScript code. I added a counter variable so you can see that it is working correctly.
$('#answer').on('click', function() {
feedback('hey there');
});
var counter = 0;
function feedback(message) {
$('#feedback').remove();
$('.answers').append('<div id="feedback">' + message + ' ' + counter + '</div>');
counter++;
}
First things first, i'd not like that as a user.
The best way to do is probably using a small flash applet that plays your sound in the background.

I had the same problem.
The solution from depa is absolutely correct.
Just make sure that u have a user configured to use PostgreSQL.
Check the file:
$ ls /etc/postgresql/9.1/main/pg_hba.conf -l
The permission of this file should be given to the user you have registered your psql with.
Further. If you are good till now..
Update as per @depa's instructions.
i.e.
$ sudo nano /etc/postgresql/9.1/main/pg_hba.conf
and then make changes.
My vote is string.Join
No need for lambda evaluations and temporary functions to be created, fewer function calls, less stack pushing and popping.
Note: new leader as of 2015-08-20.
I ran each of the various conversion methods through some crude Stopwatch
performance testing, a run with a random sentence (n=61, 1000 iterations) and a run with a Project Gutenburg text (n=1,238,957, 150 iterations). Here are the results, roughly from fastest to slowest. All measurements are in ticks (10,000 ticks = 1 ms) and all relative notes are compared to the [slowest] StringBuilder
implementation. For the code used, see below or the test framework repo where I now maintain the code for running this.
WARNING: Do not rely on these stats for anything concrete; they are simply a sample run of sample data. If you really need top-notch performance, please test these methods in an environment representative of your production needs with data representative of what you will use.

Lookup tables have taken the lead over byte manipulation. Basically, there is some form of precomputing what any given nibble or byte will be in hex. Then, as you rip through the data, you simply look up the next portion to see what hex string it would be. That value is then added to the resulting string output in some fashion. For a long time byte manipulation, potentially harder to read by some developers, was the top-performing approach.
Your best bet is still going to be finding some representative data and trying it out in a production-like environment. If you have different memory constraints, you may prefer a method with fewer allocations to one that would be faster but consume more memory.

Added Waleed's answer to analysis. Quite fast.
Added string.Concat
Array.ConvertAll
variant for completeness (requires .NET 4.0). On par with string.Join
version.
Test repo includes more variants such as StringBuilder.Append(b.ToString("X2"))
. None upset the results any. foreach
is faster than {IEnumerable}.Aggregate
, for instance, but BitConverter
still wins.
Added Mykroft's SoapHexBinary
answer to analysis, which took over third place.
Added CodesInChaos's byte manipulation answer, which took over first place (by a large margin on large blocks of text).
Added Nathan Moinvaziri's lookup answer and the variant from Brian Lambert's blog. Both rather fast, but not taking the lead on the test machine I used (AMD Phenom 9750).
Added @CodesInChaos's new byte-based lookup answer. It appears to have taken the lead on both the sentence tests and the full-text tests.
Added airbreather's optimizations and unsafe
variant to this answer's repo. If you want to play in the unsafe game, you can get some huge performance gains over any of the prior top winners on both short strings and large texts.

Python does not have unary increment/decrement operators (--
/++
). Instead, to increment a value, use
a += 1
But be careful here. If you're coming from C, even this is different in python. Python doesn't have "variables" in the sense that C does, instead python uses names and objects, and in python int
s are immutable.
so lets say you do
a = 1
What this means in python is: create an object of type int
having value 1
and bind the name a
to it. The object is an instance of int
having value 1
, and the name a
refers to it. The name a
and the object to which it refers are distinct.
Now lets say you do
a += 1
Since int
s are immutable, what happens here is as follows:
a
refers to (it is an int
with id 0x559239eeb380
)0x559239eeb380
(it is 1
)int
object with value 2
(it has object id 0x559239eeb3a0
)a
to this new objecta
refers to object 0x559239eeb3a0
and the original object (0x559239eeb380
) is no longer refered to by the name a
. If there aren't any other names refering to the original object it will be garbage collected later.Give it a try yourself:
a = 1
print(hex(id(a)))
a += 1
print(hex(id(a)))
Also, you can do it with css selectors:
form#myform input[type='submit']
space beween elements in css elector means searching input[type='submit'] that elements at any depth of parent form#myform element
On Mac OS X, the way I enabled Jenkins to pull from my (private) Github repo is:
First, ensure that your user owns the Jenkins directory
sudo chown -R me:me /Users/Shared/Jenkins
Then edit the LaunchDaemon plist for Jenkins (at /Library/LaunchDaemons/org.jenkins-ci.plist) so that your user is the GroupName and the UserName:
<key>GroupName</key>
<string>me</string>
...
<key>UserName</key>
<string>me</string>
Then reload Jenkins:
sudo launchctl unload -w /Library/LaunchDaemons/org.jenkins-ci.plist
sudo launchctl load -w /Library/LaunchDaemons/org.jenkins-ci.plist
Then Jenkins, since it's running as you, has access to your ~/.ssh directory which has your keys.

WCF is a newer technology that is a viable alternative in many instances. ASP is great and works well, but I personally prefer WCF. And you can do it in .Net 4.5.
Create a new project. Right-Click on the project in solution explorer, select "Add Service Reference"
Create a textbox and button in the new application. Below is my click event for the button:
private void btnGo_Click(object sender, EventArgs e)
{
ServiceReference1.Service1Client testClient = new ServiceReference1.Service1Client();
//Add error handling, null checks, etc...
int iValue = int.Parse(txtInput.Text);
string sResult = testClient.GetData(iValue).ToString();
MessageBox.Show(sResult);
}
And you're done.
This is because of implicit conversion. The variables b, c, d
are of float
type. But the /
operator sees two integers it has to divide and hence returns an integer in the result which gets implicitly converted to a float
by the addition of a decimal point. If you want float divisions, try making the two operands to the /
floats. Like follows.
#include <stdio.h>
int main() {
int a;
float b, c, d;
a = 750;
b = a / 350.0f;
c = 750;
d = c / 350;
printf("%.2f %.2f", b, d);
// output: 2.14 2.14
return 0;
}
You should never use listview
inside scrollview
. Instead you should use NestedScrollView
as parent and RecyclerView inside that.... as it handles a lot of scrolling issues
NSString *str = @"hello";
NSData *data = [NSData dataWithBytes:str.UTF8String length:str.length];
If you have div next each other like this
<div id="1" style="float:left; margin-right:5px">
</div>
<div id="2" style="float:left">
</div>
This should work!

By using lambdaj you can sort a collection of your contacts (for example by their name) as it follows
sort(contacts, on(Contact.class).getName());
or by their address:
sort(contacts, on(Contacts.class).getAddress());
and so on. More in general, it offers a DSL to access and manipulate your collections in many ways, like filtering or grouping your contacts based on some conditions, aggregate some of their property values, etc.
To understand why we need constraints, you must first understand the value of data integrity.
Data Integrity refers to the validity of data. Are your data valid? Are your data representing what you have designed them to?
What weird questions I ask you might think, but sadly enough all too often, databases are filled with garbage data, invalid references to rows in other tables, that are long gone... and values that doesn't mean anything to the business logic of your solution any longer.
All this garbage is not alone prone to reduce your performance, but is also a time-bomb under your application logic that eventually will retreive data that it is not designed to understand.
Constraints are rules you create at design-time that protect your data from becoming corrupt. It is essential for the long time survival of your heart child of a database solution. Without constraints your solution will definitely decay with time and heavy usage.
You have to acknowledge that designing your database design is only the birth of your solution. Here after it must live for (hopefully) a long time, and endure all kinds of (strange) behaviour by its end-users (ie. client applications). But this design-phase in development is crucial for the long-time success of your solution! Respect it, and pay it the time and attention it requires.
A wise man once said: "Data must protect itself!". And this is what constraints do. It is rules that keep the data in your database as valid as possible.
There are many ways of doing this, but basically they boil down to:
sys.check_constraints
view in the AdventureWorks sample databaseAs I've hinted here, it takes some thorough considerations to construct the best and most defensive constraint approach for your database design. You first need to know the possibilities and limitations of the different constraint types above. Further reading could include:
FOREIGN KEY Constraints - Microsoft

What I usually do is have a registry "Open Here" helper in order to open a cygwin shell with administrative privileges quite easy from anywhere in my computer.

PS: You can grab this code, copy and paste it and save it in a name.reg file to run it... or you can manually add the values.
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_

I was having similar issues connecting to OpenSUSE 13.1 MySQL database with LibreOffice. Update LibreOffice to latest stable "Still" package, then make sure the database is accessible using a tool such as phpMyAdmin. Make sure your user is linked to localhost and not "%" (any). This worked for me, I am able to add data thru LibreOffice.
Side note - LibreOffice Base will not supply "native connection" via MySQL on first attempt, you will need to use the back button, then try again to see the options.
Hope this helps.
You can try with Picasso, it's really nice and easy. Don't forget to add the permissions in the manifest.
Picasso.with(context)
.load("http://ImageURL")
.resize(width,height)
.into(imageView );
You can also take a look at a tutorial here : Youtube / Github
You can display an image in your own window using Tkinter, w/o depending on image viewers installed in your system:
import Tkinter as tk
from PIL import Image, ImageTk # Place this at the end (to avoid any conflicts/errors)
window = tk.Tk()
#window.geometry("500x500") # (optional)
imagefile = {path_to_your_image_file}
img = ImageTk.PhotoImage(Image.open(imagefile))
lbl = tk.Label(window, image = img).pack()
window.mainloop()
For Python 3, replace import Tkinter as tk
with import tkinter as tk
.
It's just about the remainders. Let me show you how
10 % 5=0
9 % 5=4 (because the remainder of 9 when divided by 5 is 4)
8 % 5=3
7 % 5=2
6 % 5=1
5 % 5=0 (because it is fully divisible by 5)
Now we should remember one thing, mod means remainder so
4 % 5=4
but why 4? because 5 X 0 = 0 so 0 is the nearest multiple which is less than 4 hence 4-0=4
Try to use https://www.pagedjs.org/. It polyfills page counter, header-/footer-functionality for all major browsers.
@page {
@bottom-left {
content: counter(page) ' of ' counter(pages);
}
}
It's so much more comfortable compared to alternatives like PrinceXML, Antennahouse, WeasyPrince, PDFReactor, etc ...
And it is totally free! No pricing or whatever. It really saved my life!
You can also use myform.$invalid
E.g.
if($scope.myform.$invalid){return;}
let viewDemo = UIView()
viewDemo.frame = CGRect(x: 50, y: 50, width: 50, height: 50)
self.view.addSubview(viewDemo)
To determine if a String contains an upper case and a lower case char, you can use the following:
boolean hasUppercase = !password.equals(password.toLowerCase());
boolean hasLowercase = !password.equals(password.toUpperCase());
This allows you to check:
if(!hasUppercase)System.out.println("Must have an uppercase Character");
if(!hasLowercase)System.out.println("Must have a lowercase Character");
Essentially, this works by checking if the String is equal to its entirely lowercase, or uppercase equivalent. If this is not true, then there must be at least one character that is uppercase or lowercase.
As for your other conditions, these can be satisfied in a similar way:
boolean isAtLeast8 = password.length() >= 8;//Checks for at least 8 characters
boolean hasSpecial = !password.matches("[A-Za-z0-9 ]*");//Checks at least one char is not alpha numeric
boolean noConditions = !(password.contains("AND") || password.contains("NOT"));//Check that it doesn't contain AND or NOT
With suitable error messages as above.
Per HTML syntax, and even HTML5, the following are all valid options:
<option value=""asd">test</option>
<option value=""asd">test</option>
<option value='"asd'>test</option>
<option value='"asd'>test</option>
<option value='"asd'>test</option>
<option value="asd>test</option>
<option value="asd>test</option>
Note that if you are using XML syntax the quotes (single or double) are required.
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date(); System.out.println(dateFormat.format(date)); //2014/08/06 15:59:4
Yes it stops execution so this is generally preferable to HAVING COUNT(*) > 0
which often won't.
With EXISTS
if you look at the execution plan you will see that the actual number of rows coming out of table1
will not be more than 1 irrespective of number of matching records.
In some circumstances SQL Server can convert the tree for the COUNT
query to the same as the one for EXISTS
during the simplification phase (with a semi join and no aggregate operator in sight) an example of that is discussed in the comments here.
For more complicated sub trees than shown in the question you may occasionally find the COUNT
performs better than EXISTS
however. Because the semi join needs only retrieve one row from the sub tree this can encourage a plan with nested loops for that part of the tree - which may not work out optimal in practice.
Solutions which are described above, even with unique CookieFile names, can cause a lot of problems on scale.
We had to serve a lot of authentications with this solution and our server went down because of high file read write actions.
The solution for this was to use Apache Reverse Proxy and omit CURL requests at all.
Details how to use Proxy on Apache can be found here: https://httpd.apache.org/docs/2.4/howto/reverse_proxy.html
TreeMap, which is an implementation of the SortedMap interface, would work.
How do I use it ?
Map<Float, MyObject> map = new TreeMap<Float, MyObject>();
The two errors you have in your code are very different.
The first problem is that you're initializing and populating your Map
in the body of the class without a statement.
You can either have a static Map
and a static {//TODO manipulate Map}
statement in the body of the class, or initialize and populate the Map in a method or in the class' constructor.
The second problem is that you cannot treat a Map
syntactically like an array
, so the statement data["John"] = "Taxi Driver";
should be replaced by data.put("John", "Taxi Driver")
.
If you already have a "John" key in your HashMap
, its value will be replaced with "Taxi Driver".
While there might be a way I would tend to keep that kind of logic out of the Model. I agree that you shouldn't put that in the view (keep it skinny) but unless the model is returning a url as a piece of data to the controller, the routing stuff should be in the controller.
Use Array.extend
instead of Array.push
for > 150,000 records.
if (!Array.prototype.extend) {
Array.prototype.extend = function(arr) {
if (!Array.isArray(arr)) {
return this;
}
for (let record of arr) {
this.push(record);
}
return this;
};
}
@Rollerball is right. The wait()
is called, so that the thread can wait for some condition to occur when this wait()
call happens, the thread is forced to give up its lock.
To give up something, you need to own it first. Thread needs to own the lock first.
Hence the need to call it inside a synchronized
method/block.
Yes, I do agree with all the above answers regarding the potential damages/inconsistencies if you did not check the condition within synchronized
method/block. However as @shrini1000 has pointed out, just calling wait()
within synchronized block will not avert this inconsistency from happening.
You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.
import threading
import time
import inspect
class Thread(threading.Thread):
def __init__(self, t, *args):
threading.Thread.__init__(self, target=t, args=args)
self.start()
count = 0
lock = threading.Lock()
def incre():
global count
caller = inspect.getouterframes(inspect.currentframe())[1][3]
print "Inside %s()" % caller
print "Acquiring lock"
with lock:
print "Lock Acquired"
count += 1
time.sleep(2)
def bye():
while count < 5:
incre()
def hello_there():
while count < 5:
incre()
def main():
hello = Thread(hello_there)
goodbye = Thread(bye)
if __name__ == '__main__':
main()
Sample output:
...
Inside hello_there()
Acquiring lock
Lock Acquired
Inside bye()
Acquiring lock
Lock Acquired
...
Use the Query like this in the shell:
1. Use database_name
e.g: use database_name
2. Which returns only assets particular field information when matched , _id:0
specifies not to display ID in the result
db.collection_name.find( { "Search_Field": "value" },
{ "Field_to_display": 1,_id:0 } )
import re
re.search(r"(?<=AAA).*?(?=ZZZ)", your_text).group(0)
The above as-is will fail with an AttributeError
if there are no "AAA" and "ZZZ" in your_text
your_text.partition("AAA")[2].partition("ZZZ")[0]
The above will return an empty string if either "AAA" or "ZZZ" don't exist in your_text
.
PS Python Challenge?
For me my forked branch was not in sync with the master branch. So I went to bitbucket and synced and merged my forked branch and then tried to take the pull. Then it worked fine.
Programmatically use : editText.setBackground(null)
From xml
use: android:background="@null"
As string data types have variable length, it is by default stored as object type. I faced this problem after treating missing values too. Converting all those columns to type 'category' before label encoding worked in my case.
df[cat]=df[cat].astype('category')
And then check df.dtypes and perform label encoding.
Maybe the following is what you are looking for:
SELECT name, pathfilename
FROM table1
NATURAL JOIN table2
NATURAL JOIN table3
WHERE name = 'John';
I don't know if this what you want but try to remove overflow: hidden from #wrap
If Android Studio directly opening your project instead of setup window, then just close the windows of all projects. Now you will able to see the startup window. If SDK is missing then it will provide option to download SDK and other required tools.
It works for me.
You need Linq - System.Xml.Linq to be precise.
You can create XML using XElement from scratch - that should pretty much sort you out.
Both are variable the only difference is that Mutable variable and immutable variable and there is nothing more difference. var is Mutable variable and val is immutable.In simple Language var can change is value after initialization value val is constant and it cannot change it value after initialization the value.

I recommend to check event.metaKey as well. If that's set to true, the user might be doing something like cmd-A to select all the text in the field. You should allow that too.
