Varying is an alias for varchar, so no difference, see documentation :)
The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.
Only you need to add other parameter in your route, the parameter is useAsDefault:true. For example, if you want the DashboardComponent as default you need to do this:
@RouteConfig([
{ path: '/Dashboard', component: DashboardComponent , useAsDefault:true},
.
.
.
])
I recomend you to add names to your routes.
{ path: '/Dashboard',name:'Dashboard', component: DashboardComponent , useAsDefault:true}
You can use tabindex="-1"
.
The W3C HTML5 specification supports negative tabindex
values:
If the value is a negative integer
The user agent must set the element's tabindex focus flag, but should not allow the element to be reached using sequential focus navigation.
Watch out though that this is a HTML5 feature and might not work with old browsers.
To be W3C HTML 4.01 standard (from 1999) compliant, tabindex would need to be positive.
Sample usage below in pure HTML.
<input />_x000D_
<input tabindex="-1" placeholder="NoTabIndex" />_x000D_
<input />
_x000D_
correct syntax for mysql insert into statement using post method is:
$sql="insert into ttable(username,password) values('$_POST[username]','$_POST[password]')";
To Print key-value pair, for example:
players = {
'lebron': 'lakers',
'giannis': 'milwakee bucks',
'durant': 'brooklyn nets',
'kawhi': 'clippers',
}
for player,club in players.items():
print(f"\n{player.title()} is the leader of {club}")
The above code, key-value pair:
'lebron': 'lakers', - Lebron is key and lakers is value
for loop - specify key, value in dictionary.item():
Now Print (Player Name is the leader of club).
the Output is:
#Lebron is the leader of lakers
#Giannis is the leader of milwakee bucks
#Durant is the leader of brooklyn nets
#Kawhi is the leader of clippers
The ToString
function has many overloads - the method group would be the group consisting of all the different overloads for that function.
Be careful, the solution proposed with $a = array_combine($a, $a);
will not work for numeric values.
I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384)
to be the keys as well as the values however PHP manual states:
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
So I solved it like this:
foreach($array as $key => $val) {
$new_array[$val]=$val;
}
Another just for testing solution to this is by simply changing your bundle id. Just don't forget to change it back once you're done!
I ran into a similar bind in a render function and ended up passing the context of this
in the following way:
{someList.map(function(listItem) {
// your code
}, this)}
I've also used:
{someList.map((listItem, index) =>
<div onClick={this.someFunction.bind(this, listItem)} />
)}
I had the same problem.
Here is a workaround
android:inputType="textNoSuggestions|textVisiblePassword"
android:maxLength="6"
The download
property of links is new and not is supported in Internet Explorer (see the compatibility table here). For a cross-browser solution to this problem I would take a look at FileSaver.js
https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/setRangeText
I'm not sure about the browser support for this though.
Tested in Chrome 81.

Tested in Chrome 47, 81, and Firefox 76.
If you want to change the value of the currently selected text while you're typing in the same field (for an autocomplete or similar effect), pass document.activeElement
as the first parameter.
It's not the most elegant way to do this, but it's pretty simple.
Example usages:
typeInTextarea('hello');
typeInTextarea('haha', document.getElementById('some-id'));
You can use <LinearLayout>
to group elements horizontaly. Also you should use style to set margins, background and other properties. This will allow you not to repeat code for every label you use.
Here is an example:
<LinearLayout
style="@style/FormItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
style="@style/FormLabel"
android:layout_width="wrap_content"
android:layout_height="@dimen/default_element_height"
android:text="@string/name_label"
/>
<EditText
style="@style/FormText.Editable"
android:id="@+id/cardholderName"
android:layout_width="wrap_content"
android:layout_height="@dimen/default_element_height"
android:layout_weight="1"
android:gravity="right|center_vertical"
android:hint="@string/card_name_hint"
android:imeOptions="actionNext"
android:singleLine="true"
/>
</LinearLayout>
Also you can create a custom view base on the layout above. Have you looked at Creating custom view ?
In your example problem is passed table name pattern in getTables function of DatabaseMetaData.
Some database supports Uppercase identifier, some support lower case identifiers. For example oracle fetches the table name in upper case, while postgreSQL fetch it in lower case.
DatabaseMetaDeta provides a method to determine how the database stores identifiers, can be mixed case, uppercase, lowercase see:http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#storesMixedCaseIdentifiers()
From below example, you can get all tables and view of providing table name pattern, if you want only tables then remove "VIEW" from TYPES array.
public class DBUtility {
private static final String[] TYPES = {"TABLE", "VIEW"};
public static void getTableMetadata(Connection jdbcConnection, String tableNamePattern, String schema, String catalog, boolean isQuoted) throws HibernateException {
try {
DatabaseMetaData meta = jdbcConnection.getMetaData();
ResultSet rs = null;
try {
if ( (isQuoted && meta.storesMixedCaseQuotedIdentifiers())) {
rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
} else if ( (isQuoted && meta.storesUpperCaseQuotedIdentifiers())
|| (!isQuoted && meta.storesUpperCaseIdentifiers() )) {
rs = meta.getTables(
StringHelper.toUpperCase(catalog),
StringHelper.toUpperCase(schema),
StringHelper.toUpperCase(tableNamePattern),
TYPES
);
}
else if ( (isQuoted && meta.storesLowerCaseQuotedIdentifiers())
|| (!isQuoted && meta.storesLowerCaseIdentifiers() )) {
rs = meta.getTables(
StringHelper.toLowerCase( catalog ),
StringHelper.toLowerCase(schema),
StringHelper.toLowerCase(tableNamePattern),
TYPES
);
}
else {
rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
}
while ( rs.next() ) {
String tableName = rs.getString("TABLE_NAME");
System.out.println("table = " + tableName);
}
}
finally {
if (rs!=null) rs.close();
}
}
catch (SQLException sqlException) {
// TODO
sqlException.printStackTrace();
}
}
public static void main(String[] args) {
Connection jdbcConnection;
try {
jdbcConnection = DriverManager.getConnection("", "", "");
getTableMetadata(jdbcConnection, "tbl%", null, null, false);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Just a mention with jQuery v3.2.1 and Laravel 5.6.
Case 1: The JS object posted directly, like:
$.post("url", {name:'John'}, function( data ) {
});
Corresponding Laravel PHP code should be:
parse_str($request->getContent(),$data); //JSON will be parsed to object $data
Case 2: The JSON string posted, like:
$.post("url", JSON.stringify({name:'John'}), function( data ) {
});
Corresponding Laravel PHP code should be:
$data = json_decode($request->getContent(), true);
The answers using grep are wrong. You need to add an -x option to match the entire line otherwise lines like #text to add
will still match when looking to add exactly text to add
.
So the correct solution is something like:
grep -qxF 'include "/configs/projectname.conf"' foo.bar || echo 'include "/configs/projectname.conf"' >> foo.bar
try this
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string = dateFormat.format(new Date());
System.out.println(string);
you can create any format see this
For anyone who is aware of the risks this implementation imposes, to have the password sync to your ViewModel simply add Mode=OneWayToSource.
XAML
<PasswordBox
ff:PasswordHelper.Attach="True"
ff:PasswordHelper.Password="{Binding Path=Password, Mode=OneWayToSource}" />
if any( [ i>'z' or i<'a' for i in raw_input]):
print "Error: Contains illegal characters"
elif len(raw_input)>15:
print "Very long string"
What you're trying to do is essentially to find a path between two vertices in a (directed?) graph check out Dijkstra's algorithm if you need shortest path or write a simple recursive function if you need whatever paths exist.
The proper way to install an MSI silently is via the msiexec.exe command line
as follows:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"
Quick explanation:
/L*V "C:\Temp\msilog.log"= verbose logging
/QN = run completely silently
/i = run install sequence
There is a much more comprehensive answer here: Batch script to install MSI. This answer provides details on the msiexec.exe command line options and a description of how to find the "public properties" that you can set on the command line at install time. These properties are generally different for each MSI.
It is a build target that is not a filename.
in the 'default' directory if you have not specifically mentioned your location.
you can use describe and describe extended to know about the table structure.
Create a new Java project in Eclipse. This will create a src folder (to contain your source files).
Also create a lib folder (the name isn't that important, but it follows standard conventions).
Copy the ./com/*
folders into the /src
folder (you can just do this using the OS, no need to do any fancy importing or anything from the Eclipse GUI).
Copy any dependencies (jar
files that your project itself depends on) into /lib
(note that this should NOT include the TGGL jar
- thanks to commenter Mike Deck for pointing out my misinterpretation of the OPs post!)
Copy the other TGGL stuff into the root project folder (or some other folder dedicated to licenses that you need to distribute in your final app)
Back in Eclipse, select the project you created in step 1, then hit the F5 key (this refreshes Eclipse's view of the folder tree with the actual contents.
The content of the /src
folder will get compiled automatically (with class files placed in the /bin file that Eclipse generated for you when you created the project). If you have dependencies (which you don't in your current project, but I'll include this here for completeness), the compile will fail initially because you are missing the dependency jar files
from the project classpath.
Finally, open the /lib
folder in Eclipse, right click
on each required jar file
and choose Build Path->Add
to build path.
That will add that particular jar to the classpath for the project. Eclipse will detect the change and automatically compile the classes that failed earlier, and you should now have an Eclipse project with your app in it.
Your parameter for the request options in http.put() should actually be of type RequestOptions. Try something like this:
let headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('authentication', `${student.token}`);
let options = new RequestOptions({ headers: headers });
return this.http
.put(url, JSON.stringify(student), options)
Some of the databases such as MS ACCESS
or RODBC
may not support the SQL SERVER
functions, but for any database that has the FORMAT
function you can simply do this:
SELECT FORMAT(<your-date-field>,"YYYY-MM") AS year-date FROM <your-table>
System.Diagnostics.Process.Start("c:\\batchfilename.bat");
this simple line will execute the batch file.
I think this is what you are looking for -
select Address1+Address2 as CompleteAddress from YourTable
where Address1+Address2 like '%YourSearchString%'
To prevent a compound word being created when we append address1 with address2, you can use this -
select Address1 + ' ' + Address2 as CompleteAddress from YourTable
where Address1 + ' ' + Address2 like '%YourSearchString%'
So, '123 Center St' and 'Apt 3B' will not be '123 Center StApt 3B' but will be '123 Center St Apt 3B'.
Use window.confirm()
instead of window.alert()
.
HTML:
<input type="submit" onclick="return clicked();" value="Button" />
JavaScript:
function clicked() {
return confirm('clicked');
}
zlib
handles the deflate compression/decompression algorithm, but there is more than that in a ZIP file.
You can try libzip. It is free, portable and easy to use.
UPDATE: Here I attach quick'n'dirty example of libzip, with all the error controls ommited:
#include <zip.h>
int main()
{
//Open the ZIP archive
int err = 0;
zip *z = zip_open("foo.zip", 0, &err);
//Search for the file of given name
const char *name = "file.txt";
struct zip_stat st;
zip_stat_init(&st);
zip_stat(z, name, 0, &st);
//Alloc memory for its uncompressed contents
char *contents = new char[st.size];
//Read the compressed file
zip_file *f = zip_fopen(z, name, 0);
zip_fread(f, contents, st.size);
zip_fclose(f);
//And close the archive
zip_close(z);
//Do something with the contents
//delete allocated memory
delete[] contents;
}

If the web service being invoked uses windows integrated security, creating a NetworkCredential
from the current WindowsIdentity
should be sufficient to allow the web service to use the current users windows login. However, if the web service uses a different security model, there isn't any way to extract a users password from the current identity ... that in and of itself would be insecure, allowing you, the developer, to steal your users passwords. You will likely need to provide some way for your user to provide their password, and keep it in some secure cache if you don't want them to have to repeatedly provide it.
Edit: To get the credentials for the current identity, use the following:
Uri uri = new Uri("http://tempuri.org/");
ICredentials credentials = CredentialCache.DefaultCredentials;
NetworkCredential credential = credentials.GetCredential(uri, "Basic");
You can also use the Cast() operation :
Declare @name varchar(100);
set @name='....';
Select Cast(@name as varchar(10)) as new_name
I have tried some hours now and the easiest way to stop browsers to jump to the anchor instead of scrolling to it is: Using another anchor (an id you do not use on the site). So instead of linking to "http://#YourActualID" you link to "http://#NoIDonYourSite". Poof, browsers won’t jump anymore.
Then just check if an anchor is set (with the script provided below, that is pulled out of the other thread!). And set your actual id you want to scroll to.
$(document).ready(function(){
$(window).load(function(){
// Remove the # from the hash, as different browsers may or may not include it
var hash = location.hash.replace('#','');
if(hash != ''){
// Clear the hash in the URL
// location.hash = ''; // delete front "//" if you want to change the address bar
$('html, body').animate({ scrollTop: $('#YourIDtoScrollTo').offset().top}, 1000);
}
});
});
See https://lightningsoul.com/media/article/coding/30/YOUTUBE-SOCKREAD-SCRIPT-FOR-MIRC#content for a working example.
Let's take an example: You want to contribute to django, so you fork its repository. In the while you work on your feature, there is much work done on the original repo by other people. So the code you forked is not the most up to date. setting a remote upstream and fetching it time to time makes sure your forked repo is in sync with the original repo.
You can do it using javascript
Plain javascript
var iframe = document.getElementsByTagName('iframe')[0];
iframe.style.background = 'white';
iframe.contentWindow.document.body.style.backgroundColor = 'white';
jQuery
$('iframe').css('background', 'white');
$('iframe').contents().find('body').css('backgroundColor', 'white');
Not sure if this is correct in any sense but this seems to work for me.
someHeader.h
inline int someVar;
I don't have linking/multiple definition issues and it "just works"... ;- )

Don't name your current python script with the name of some other module you import
Solution: rename your working python script
Example:
medicaltorch.py
from medicaltorch import datasets as mt_datasets
where medicaltorch
is supposed to be an installed moduleThis will fail with the ImportError
. Just rename your working python script in 1.

I'm rather shocked that this has not been answered since the solution is very simple.
As mentioned in previous posts, you would not want to convert it using C#, but just once. This is easy to do with PuTTYGen.

I did had a problem with the most of solutions, since I was trying to use a checkbox with a specific style. I was in need of the values of the checkbox to send them to post from a list, once the values were collected, needed to save it. I did manage to work it around after a while.

The spread Operator is a shortcut for that
You map your dispatcher on *.do:
<servlet-mapping>
<servlet-name>Dispatcher</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
but your controller is mapped on an url without .do:
@RequestMapping("/editPresPage")
Try changing this to:
@RequestMapping("/editPresPage.do")
when I load in a json object I usually setup the relationships by iterating through the object arrays like this:
for (var i = 0; i < some.json.objectarray.length; i++) {
var p = some.json.objectarray[i];
for (var j = 0; j < p.somechildarray.length; j++) {
p.somechildarray[j].parent = p;
}
}
then you can access the parent object of some object in the somechildarray by using .parent
My problem was that I was trying to create a ASPX web application in a subfolder of a folder that already had a web.config file, and
So I opened up the parent folder in Visual Studio as a Web Site (Open > Web Site) I was able to add a new item ASPX page that had no issue parsing/loading.
Reference the jquery min version that includes ajax:
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
Also possible is to fix this with np.arange() instead of range which works for float numbers:
import numpy as np
for i in np.arange(c/10):
Actually, there is a gem called Jsonable, https://github.com/treeder/jsonable. It's pretty sweet.
$('#test').attr('checked','checked');
$('#test').removeAttr('checked');
If you want beautiful and responsive alert dialog then you can use flutter packages like
rflutter alert ,fancy dialog,rich alert,sweet alert dialogs,easy dialog & easy alert
These alerts are good looking and responsive. Among them rflutter alert is the best. currently I am using rflutter alert for my apps.
Or you could use something like the following. Pay attention to "\n":

I,
And I faced this issue with EGit and here is how I fixed it..
Yes, someone committed the changes before I commit my changes. So the changes are rejected.
After this error, the changes gets actually committed to local repository.
I did not want to just Pull
the changes because I wanted to maintain linear history
as pointed out in - In what cases could `git pull` be harmful?
So, I executed following steps
Fetch from Upstream
- it fetches remote updates (refs and objects) but no updates are made locally. for more info refer What is the difference between 'git pull' and 'git fetch'?Rebase...
- this open a popup, click on Preserve merges during rebase
see whyRebase button
conflict(s)
, go to step 6 else step 11Rebase Result
popup would appear, just click on OK
file comparator
would open up, you need to modify left side file
. Git Staging
viewstage the changes
. i.e. add to index
Rebase
-> Continue
. repeat 7 to 10 until all conflicts are resolved.History
view, select your commit row and select Push Commit
Rebase Commits of local.......
checkbox and click next. refer why - Git: rebase onto development branch from upstreamFinish
Note: if you have multiple local repository commits, you need to squash them in one commit to avoid multiple merges.
In your file.php of request ajax, can set value header.
<?php header('Access-Control-Allow-Origin: *'); //for all ?>
This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....
To cover the identities listed:
IIS_IUSRS:
This is analogous to the old IIS6 IIS_WPG
group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.
IUSR:
This account is analogous to the old IUSR_<MACHINE_NAME>
local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).
For more information about IIS_IUSRS
and IUSR
see:
DefaultAppPool:
If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name>
will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool
created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>
. You also won't see these pool accounts in your computers User Manager. See the following for more information:
ASP.NET v4.0:
-
This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool
above.
NETWORK SERVICE:
-
The NETWORK SERVICE
account is a built-in identity introduced on Windows 2003. NETWORK SERVICE
is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).
In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE
). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" />
setting in web.config
file locally (if that setting is locked then it would need to be done by an admin in the machine.config
file).
Setting <identity impersonate="true">
is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).
In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR
or a specific custom anonymous account.
LOCAL SERVICE:
The LOCAL SERVICE
account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:
LOCAL SYSTEM:
You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.
In Practice:
In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity
. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity
:
In the website you should then configure the Authentication feature:
Right click and edit the Anonymous Authentication entry:
Ensure that "Application pool identity" is selected:
When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0
pool permissions then you can either do this via Explorer:
Click the "Check Names" button:
Or you can do this using the ICACLS.EXE
utility:
icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)
...or...if you site's application pool is called BobsCatPicBlog
then:
icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)
I hope this helps clear things up.
Update:
I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:
The difference between the 'Local System' account and the 'Network Service' account?

It's also much easier to manage native builds. Ant and Maven are effectively Java-only. Some plugins exist for Maven that try to handle some native projects, but they don't do an effective job. Ant tasks can be written that compile native projects, but they are too complex and awkward.
We do Java with JNI and lots of other native bits. Gradle simplified our Ant mess considerably. When we started to introduce dependency management to the native projects it was messy. We got Maven to do it, but the equivalent Gradle code was a tiny fraction of what was needed in Maven, and people could read it and understand it without becoming Maven gurus.
I like a single line open and close:
if [ ]; then ##
...
...
fi; ##
The '##' helps me easily find the start and end to the block comment. I can stick a number after the '##' if I've got a bunch of them. To turn off the comment, I just stick a '1' in the '[ ]'. I also avoid some issues I've had with single-quotes in the commented block.
You have not provided enough code to help You likely submit the form and reload the page OR you have an object on the page like an embedded PDF that steals the focus.
Here is the canonical plain javascript method of validating a form It can be improved with onubtrusive JS which will remove the inline script, but this is the starting point DEMO
function validate(formObj) {
document.getElementById("errorMsg").innerHTML = "";
var quantity = formObj.quantity;
if (isNaN(quantity)) {
quantity.value="";
quantity.focus();
document.getElementById("errorMsg").innerHTML = "Only numeric value is allowed";
return false;
}
return true; // allow submit
}
Here is the HTML
<form onsubmit="return validate(this)">
<input type="text" name="quantity" value="" />
<input type="submit" />
</form>
<span id="errorMsg"></span>
"currently yes but i think it might cause problems at peak moments" I can confirm, that I had a problem where I got timeouts because of peak requests. After I set the max pool size, the application ran without any problems. IIS 7.5 / ASP.Net
Here's an updated ajax call for when you are using JSON with jQuery > 1.9:
$.ajax({
url: '/v1/object/3.json',
method: 'DELETE',
contentType: 'application/json',
success: function(result) {
// handle success
},
error: function(request,msg,error) {
// handle failure
}
});
If I understand correctly, you want PowerShell to send the ENTER keystroke to some interactive application?
$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('title of the application window')
Sleep 1
$wshell.SendKeys('~')
If that interactive application is a PowerShell script, just use whatever is in the title bar of the PowerShell window as the argument to AppActivate (by default, the path to powershell.exe). To avoid ambiguity, you can have your script retitle its own window by using the title 'new window title'
command.
A few notes:
{ENTER}
, though they're not identical - that's the keypad's ENTER key. A complete list is available here: http://msdn.microsoft.com/en-us/library/office/aa202943%28v=office.10%29.aspx.Sleep 1
statement is to wait 1 second because it takes a moment for the window to activate, and if you invoke SendKeys immediately, it'll send the keys to the PowerShell window, or to nowhere.Sometimes wscript.shell's SendKeys method can be a little quirky, so if you run into problems, replace the fourth line above with this:
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SendKeys]::SendWait('~');
Trim just removes the trailing and leading whitespace. Use .replace(/ /g, "") if there are just spaces to be replaced.
this.maintabinfo = this.inner_view_data.replace(/ /g, "").toLowerCase();
This opened the default for me:
System.Diagnostics.Process.Start(e.LinkText.ToString());
To retrieve text of an auto generated span value just do this :
var al = $("#id-span-name").text();
alert(al);
@SweetSpice, use position as absolute in place of relative. It will work
#frame{
overflow: hidden;
width: 860px;
height: 100%;
position: absolute;
}
textarea.addEventListener("keypress", textareaLengthCheck(textarea), false);
You are calling textareaLengthCheck
and then assigning its return value to the event listener. This is why it doesn't update or do anything after loading. Try this:
textarea.addEventListener("keypress",textareaLengthCheck,false);
Aside from that:
var length = textarea.length;
textarea
is the actual textarea, not the value. Try this instead:
var length = textarea.value.length;
Combined with the previous suggestion, your function should be:
function textareaLengthCheck() {
var length = this.value.length;
// rest of code
};
Instead of writing out values consider using fputcsv()
.
This may solve your problem immediately.
From experience I'll just note that while it is the C++ way to put formerly-static functions into the anonymous namespace, older compilers can sometimes have problems with this. I currently work with a few compilers for our target platforms, and the more modern Linux compiler is fine with placing functions into the anonymous namespace.
But an older compiler running on Solaris, which we are wed to until an unspecified future release, will sometimes accept it, and other times flag it as an error. The error is not what worries me, it's what it might be doing when it accepts it. So until we go modern across the board, we are still using static (usually class-scoped) functions where we'd prefer the anonymous namespace.

Use sqlcmd instead of osql if it's a 2005 database
In Python 3, print
became a function. This means that you need to include parenthesis now like mentioned below:
print("Hello World")
I just ran into the same problem. The reason was that the virtual memory file "pagefile.sys" was located on the same drive as our data files for our databases (D: drive). It had doubled in size and filled the disk but windows wasn't picking it up, i.e. it looked like we had 80 GB free when we actually didn't.
Restarting SQL server didn't help, perhaps defragment would give the OS time to free up the pagefile, but we just rebooted the server and voila, the pagefile had shrunk and everything worked fine.
What is interesting is that during the 30 min we were investigating, windows didn't calculate the size of the pagefile.sys at all (80gb). After restart windows did find the pagefile and included it's size in the total disk usage (now 40gb - which is still too big).

Are you missing a using directive for System.Linq

The macro NDEBUG
controls whether assert()
statements are active or not.
In my view, that is separate from any other debugging - so I use something other than NDEBUG
to control debugging information in the program. What I use varies, depending on the framework I'm working with; different systems have different enabling macros, and I use whatever is appropriate.
If there is no framework, I'd use a name without a leading underscore; those tend to be reserved to 'the implementation' and I try to avoid problems with name collisions - doubly so when the name is a macro.
On the Mac version I was getting the error when trying to run JSON-Clojure.json.clj, which is the script to export a database table to JSON. To get it to work I had to download the latest Clojure JAR from http://clojure.org/ and then right-click on PHPStorm app in the Finder and "Show Package Contents". Then go to Contents in there. Then open the lib folder, and see a bunch of .jar files. Copy the clojure-1.8.0.jar file from the unzipped archive I downloaded from clojure.org into the aforementioned lib folder inside the PHPStorm.app/Contents/lib. Restart the app. Now it freaking works.
EDIT: You also have to put the JSR-223 script engine into PHPStorm.app/Contents/lib. It can be built from https://github.com/ato/clojure-jsr223 or downloaded from https://www.dropbox.com/s/jg7s0c41t5ceu7o/clojure-jsr223-1.5.1.jar?dl=0 .
I was thinking along the lines of using
typeid()
...
Well, yes, it could be done by comparing: typeid().name()
. If we take the already described situation, where:
class Base;
class A : public Base {...};
class B : public Base {...};
void foo(Base *p)
{
if(/* p is A */) /* do X */
else /* do Y */
}
A possible implementation of foo(Base *p)
would be:
#include <typeinfo>
void foo(Base *p)
{
if(typeid(*p) == typeid(A))
{
// the pointer is pointing to the derived class A
}
else if (typeid(*p).name() == typeid(B).name())
{
// the pointer is pointing to the derived class B
}
}
You would use the read.csv
function; for example:
dat = read.csv("spam.csv", header = TRUE)
You can also reference this tutorial for more details.
Note: make sure the .csv
file to read is in your working directory (using getwd()
) or specify the right path to file. If you want, you can set the current directory using setwd
.
Suppose you run your program thus (using sh
syntax):
myprog arg1 arg2 'arg 3'
If you declared your main as int main(int argc, char *argv[])
, then (in most environments), your main()
will be called as if like:
p = { "myprog", "arg1", "arg2", "arg 3", NULL };
exit(main(4, p));
However, if you declared your main as int main()
, it will be called something like
exit(main());
and you don't get the arguments passed.
Two additional things to note:
main
. If a particular platform accepts extra arguments or a different return type, then that's an extension and should not be relied upon in a portable program.*argv[]
and **argv
are exactly equivalent, so you can write int main(int argc, char *argv[])
as int main(int argc, char **argv)
.Also, CasperJS provides a nice high-level interface for navigation in PhantomJS, including clicking on links and filling out forms.
Updated to add July 28, 2015 article comparing PhantomJS and CasperJS.

Using Jquery you can do something like this:
$(document).ready(function() {_x000D_
$('#btnSubmit').click(function() {_x000D_
$('#deleteFrm').submit();_x000D_
});_x000D_
_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<form action="" id="deleteFrm" method="POST">_x000D_
<a id="btnSubmit">Submit</a>_x000D_
</form>
_x000D_
It depends how long the function is. The longer the function, the greater the chance that someone modifying it in future will write data
thinking that it means the global. In fact, it means the local, but because the function is so long, it's not obvious to them that there exists a local with that name.
For your example function, I think that shadowing the global is not bad at all.
The EclipsePasteAsJavaString plug-in allows you to insert text as a Java string by Ctrl + Shift + V
Paste as usual via Ctrl+V:
some text with tabs
and new
lines
Paste as Java string via Ctrl+Shift+V
"some text\twith tabs\r\n" +
"and new \r\n" +
"lines"
If you want to get content of given directory, and only it (i.e. no subdirectories), the best way is to use opendir/readdir/closedir:
opendir my $dir, "/some/path" or die "Cannot open directory: $!";
my @files = readdir $dir;
closedir $dir;
You can also use:
my @files = glob( $dir . '/*' );
But in my opinion it is not as good - mostly because glob is quite complex thing (can filter results automatically) and using it to get all elements of directory seems as a too simple task.
On the other hand, if you need to get content from all of the directories and subdirectories, there is basically one standard solution:
use File::Find;
my @content;
find( \&wanted, '/some/path');
do_something_with( @content );
exit;
sub wanted {
push @content, $File::Find::name;
return;
}
You can use the following if you want to specify tricky formats:
df['date_col'] = pd.to_datetime(df['date_col'], format='%d/%m/%Y')
More details on format
here:
String newLine = System.getProperty("line.separator");//This will retrieve line separator dependent on OS.
System.out.println("line 1" + newLine + "line2");
I'm interpreting your question to be about getting row numbers.
as.numeric(rownames(df))
if you haven't set the rownames. Otherwise use a sequence of 1:nrow(df)
. which()
function converts a TRUE/FALSE row index into row numbers. Provided that the remote repository is origin, and that you're interested in master:
git fetch origin
git reset --hard origin/master
This tells it to fetch the commits from the remote repository, and position your working copy to the tip of its master branch.
All your local commits not common to the remote will be gone.
If you are using Python > 3.x
you don't need to install any libraries, this is directly built in the python framework. The old urllib2
package has been renamed to urllib
:
from urllib import request
response = request.urlopen("https://www.google.com")
# set the correct charset below
page_source = response.read().decode('utf-8')
print(page_source)
If your div rule is just div {...}
, then #a {...}
will be sufficient. If it is more complicated, you need a "more specific" selector, as defined by the CSS specification on specificity. (#a being more specific than div is just single aspect in the algorithm.)
You can do this today in Java with the Red5 media server from Flash. If you want to also decode and encode video in Java, you can use the Xuggler project.
I follow Douglas Crockford's code conventions for JavaScript. I also use his JSLint tool to validate following those conventions.
If nesting your grid in a border control

does not do what you want, then you are going to have to make your own control template for the grid (or border) that DOES do what you want.

Detect IE in JS using conditional comments
// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
// ie === undefined
// If you're in IE (>=5) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}
// And to detect the version:
// ie === 6 // IE6
// ie > 7 // IE8, IE9 ...
// ie < 9 // Anything less than IE9
// ----------------------------------------------------------
// UPDATE: Now using Live NodeList idea from @jdalton
var ie = (function(){
var undef,
v = 3,

all[0]
);
return v > 4 ? v : undef;

In Swift 2 you can do it in this way:
var dictionary: NSDictionary = ...
/* NSDictionary to NSData */
let data = NSKeyedArchiver.archivedDataWithRootObject(dictionary)
/* NSData to NSDictionary */
let unarchivedDictionary = NSKeyedUnarchiver.unarchiveObjectWithData(data!) as! NSDictionary
In Swift 3:
/* NSDictionary to NSData */
let data = NSKeyedArchiver.archivedData(withRootObject: dictionary)
/* NSData to NSDictionary */
let unarchivedDictionary = NSKeyedUnarchiver.unarchiveObject(with: data)

Dictionaries are specifically designed to do super fast key lookups. They are implemented as hashtables and the more entries the faster they are relative to other methods. Using the exception engine is only supposed to be done when your method has failed to do what you designed it to do because it is a large set of object that give you a lot of functionality for handling errors. I built an entire library class once with everything surrounded by try catch blocks once and was appalled to see the debug output which contained a seperate line for every single one of over 600 exceptions!

If the timing were right, the a += 100
operation would be skipped:
Processor executes at T a+100
and gets 104. But it stops, and jumps to next thread
Here, At T+1 executes a+1
with old value of a, a == 4
. So it computes 5.
Jump back (at T+2), thread 1, and write a=104
in memory.
Now back at thread 2, time is T+3 and write a=5
in memory.
Voila! The next print instruction will print 5 instead of 104.
VERY nasty bug to be reproduced and caught.
Technically any static variable or Property on a class, anywhere in your project, will be a Global variable e.g.
public static class MyGlobalVariables
{
public static string MyGlobalString { get; set; }
}
But as @SLaks says, they can 'potentially' be bad practice and dangerous, if not handled correctly. For instance, in that above example, you would have multiple requests (threads) trying to access the same Property, which could be an issue if it was a complex type or a collection, you would have to implement some form of locking.
An easy way to overcome this problem is to use 64 bit type

// To dismiss the dialog
progress.dismiss();
OR
ProgressDialog.show(this, "Loading", "Wait while loading...");
By the way, Spinner has a different meaning in Android. (It's like the select dropdown in HTML)
You should have a look at env.js. See my blog for an example how to write unit tests with env.js.
document.cookie = "cookie_name=cookie_value; max-age=31536000; path=/";
Will set the value for a year.
find . -type d -maxdepth 1
see how exceptions work by default if one vs more attributes are used (tracebacks omitted):
>>> raise Exception('bad thing happened')
Exception: bad thing happened
>>> raise Exception('bad thing happened', 'code is broken')
Exception: ('bad thing happened', 'code is broken')
so you might want to have a sort of "exception template", working as an exception itself, in a compatible way:
>>> nastyerr = NastyError('bad thing happened')
>>> raise nastyerr
NastyError: bad thing happened
>>> raise nastyerr()
NastyError: bad thing happened
>>> raise nastyerr('code is broken')
NastyError: ('bad thing happened', 'code is broken')
this can be done easily with this subclass
class ExceptionTemplate(Exception):
def __call__(self, *args):
return self.__class__(*(self.args + args))
# ...
class NastyError(ExceptionTemplate): pass
and if you don't like that default tuple-like representation, just add __str__
method to the ExceptionTemplate
class, like:
# ...
def __str__(self):
return ': '.join(self.args)
and you'll have
>>> raise nastyerr('code is broken')
NastyError: bad thing happened: code is broken
Some of the problems:

I'm an early adopter and implemented a mid-large single page application using the Facebook Flux library.
As I'm a little late to the conversation I'll just point out that despite my best hopes Facebook seem to consider their Flux implementation to be a proof of concept and it has never received the attention it deserves.
I'd encourage you to play with it, as it exposes more of the inner working of the Flux architecture which is quite educational, but at the same time it does not provide many of the benefits that libraries like Redux provide (which aren't that important for small projects, but become very valuable for bigger ones).
We have decided that moving forward we will be moving to Redux and I suggest you do the same ;)
C:\ProgramData\Oracle\Java
and delete that directory and all files contained within. You can do this from the command line using rmdir /S C:\ProgramData\Oracle\Java
rmdir /S C:\ProgramData\Oracle
Now install JDK and set the path.
Run the program.You won't find the same problem anymore.
Shorter and dealing with a column (entire, not just a section of a column):
=COUNTA(A:A)
Beware, a cell containing just a space would be included in the count.
You may have come to this question with MySQL version 8 installed (like me) and not found a satisfactory answer. You can no longer create users like this in version 8:
GRANT ALL PRIVILEGES ON *.* TO 'steves'@'[hostname].com' IDENTIFIED BY '[OBSCURED]' WITH GRANT OPTION;
The rather confusing error message that you get back is: ERROR 1410 (42000): You are not allowed to create a user with GRANT
In order to create users in version 8 you have to do it in two steps:
CREATE USER 'steves'@'[hostname].com' IDENTIFIED BY '[OBSCURED]';
GRANT ALL PRIVILEGES ON *.* TO 'steves'@'[hostname].com' WITH GRANT OPTION;
Of course, if you prefer, you can also supply a limited number of privileges (instead of GRANT ALL PRIVILEGES
), e.g. GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER
This worked for me
[ImageViewName setImage:[UIImage imageNamed: @"ImageName.png"]];
Make sure that the ImageView is declared properly in the .h file and is linked with the IB element.

Download pscp
from Putty download page, then use it from Windows Command Line CMD
as follows:
pscp username_linux_machine@ip_of_linux_machine:/home/ubuntu/myfile.ext C:\Users\Name\Downloads
Copying starts once you enter the password for the Linux machine.
Most likely, the item is being selected, you just can't tell because a different control has the focus. There are a couple of different ways that you can solve this, depending on the design of your application.
The simple solution is to set the focus to the ListView
first whenever your form is displayed. The user typically sets focus to controls by clicking on them. However, you can also specify which controls gets the focus programmatically. One way of doing this is by setting the tab index of the control to 0 (the lowest value indicates the control that will have the initial focus). A second possibility is to use the following line of code in your form's Load
event, or immediately after you set the Selected
property:
myListView.Select();
The problem with this solution is that the selected item will no longer appear highlighted when the user sets focus to a different control on your form (such as a textbox or a button).
To fix that, you will need to set the HideSelection
property of the ListView
control to False. That will cause the selected item to remain highlighted, even when the control loses the focus.
When the control has the focus, the selected item's background will be painted with the system highlight color. When the control does not have the focus, the selected item's background will be painted in the system color used for grayed (or disabled) text.
You can set this property either at design time, or through code:
myListView.HideSelection = false;
This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.
DispatchQueue.global(qos: .background).async {
// Background Thread
DispatchQueue.main.async {
// Run UI Updates
}
}
The Safari built in dev tool is great. I have to admit that Firebug on Firefox is my long time favorite, but I think that the Safari tool do a great job too!
if (window.sidebar) { // Mozilla Firefox Bookmark
window.sidebar.addPanel(document.title,location.href,"");
It adds the bookmark but in the sidebar.
Here is my attempt. It has some common 'stupidity' checks built in, making sure you don't try to set or get a member which isn't available.
You could move those 'property_exists' checks to __set and __get respectively and call them directly within magic().
<?php
class Foo {
public $Name;
public function magic($member, $value = NULL) {
if ($value != NULL) {
if (!property_exists($this, $member)) {
trigger_error('Undefined property via magic(): ' .
$member, E_USER_ERROR);
return NULL;
}
$this->$member = $value;
} else {
if (!property_exists($this, $member)) {
trigger_error('Undefined property via magic(): ' .
$member, E_USER_ERROR);
return NULL;
}
return $this->$member;
}
}
};
$f = new Foo();
$f->magic("Name", "Something");
echo $f->magic("Name") , "\n";
// error
$f->magic("Fame", "Something");
echo $f->magic("Fame") , "\n";
?>
The comments above are correct. You're missing the decorators. If you want a generic deserializer you can use this.
public static T DeserializeXMLFileToObject<T>(string XmlFilename)
{
T returnObject = default(T);
if (string.IsNullOrEmpty(XmlFilename)) return default(T);
try
{
StreamReader xmlStream = new StreamReader(XmlFilename);
XmlSerializer serializer = new XmlSerializer(typeof(T));
returnObject = (T)serializer.Deserialize(xmlStream);
}
catch (Exception ex)
{
ExceptionLogger.WriteExceptionToConsole(ex, DateTime.Now);
}
return returnObject;
}
Then you'd call it like this:
MyObjType MyObj = DeserializeXMLFileToObject<MyObjType>(FilePath);
The simplest defenition is ; padding is a space given inside the border of the container element and margin is given outside. For a element which is not a container, padding may not make much sense, but margin defenitly will help to arrange it.
you can run raw query like this way too.
DB::table('setting_colleges')->first();
Just for those new to iOS buddies (like me) who decided to have multiple cells and in a different xib file, the solution is not to have identifier but to do this:
let cell = Bundle.main.loadNibNamed("newsDetails", owner: self, options: nil)?.first as! newsDetailsTableViewCell
here newsDetails is xib file name.
The question was how to "Split List into Sublists with LINQ", but sometimes you may want those sub-lists to be references to the original list, not copies. This allows you to modify the original list from the sub-lists. In that case, this may work for you.
public static IEnumerable<Memory<T>> RefChunkBy<T>(this T[] array, int size)
{
if (size < 1 || array is null)
{
throw new ArgumentException("chunkSize must be positive");
}
var index = 0;
var counter = 0;
for (int i = 0; i < array.Length; i++)
{
if (counter == size)
{
yield return new Memory<T>(array, index, size);
index = i;
counter = 0;
}
counter++;
if (i + 1 == array.Length)
{
yield return new Memory<T>(array, index, array.Length - index);
}
}
}
Usage:
var src = new[] { 1, 2, 3, 4, 5, 6 };
var c3 = RefChunkBy(src, 3); // {{1, 2, 3}, {4, 5, 6}};
var c4 = RefChunkBy(src, 4); // {{1, 2, 3, 4}, {5, 6}};
// as extension method
var c3 = src.RefChunkBy(3); // {{1, 2, 3}, {4, 5, 6}};
var c4 = src.RefChunkBy(4); // {{1, 2, 3, 4}, {5, 6}};
var sum = c3.Select(c => c.Span.ToArray().Sum()); // {6, 15}
var count = c3.Count(); // 2
var take2 = c3.Select(c => c.Span.ToArray().Take(2)); // {{1, 2}, {4, 5}}
Feel free to make this code better.
The following commands are available with .NET Core SDK 2.1 (v2.1.300):
To list all installed .NET Core SDKs use: dotnet --list-sdks
To list all installed .NET Core runtimes use dotnet --list-runtimes
(tested on Windows as of writing, 03 Jun 2018, and again on 23 Aug 2018)
Update as of 24 Oct 2018: Better option is probably now dotnet --info
in a terminal or PowerShell window as already mentioned in other answers.
As always in python, there are of course several ways to do it, but there is one obvious way to do it.
tmpdict["ONE"]["TWO"]["THREE"]
is the obvious way to do it.
When that does not fit well with your algorithm, that may be a hint that your structure is not the best for the problem.
If you just want to just save you repetative typing, you can of course alias a subset of the dict:
>>> two_dict = tmpdict['ONE']['TWO'] # now you can just write two_dict for tmpdict['ONE']['TWO']
>>> two_dict["spam"] = 23
>>> tmpdict
{'ONE': {'TWO': {'THREE': 10, 'spam': 23}}}
The comprehensive place for Acrobat JavaScript documentation is the Acrobat SDK, which can be downloaded from the Adobe website. In the Documentation section, you will find all the material needed to work with Acrobat JavaScript.
To complete the documentation you may in addition get the specification of the JavaScript Core. My book of choice for that is "JavaScript, the Definitive Guide" by David Flanagan, published by O'Reilly.
You can also use button click event like this:
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text="Button"
OnClick="MyButtonClick" />
</ItemTemplate>
</asp:TemplateField>
protected void MyButtonClick(object sender, System.EventArgs e)
{
//Get the button that raised the event
Button btn = (Button)sender;
//Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}
You can do like this to get data:
void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple ButtonField column fields are used, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="Select")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Get the last name of the selected author from the appropriate
// cell in the GridView control.
GridViewRow selectedRow = CustomersGridView.Rows[index];
}
}
and Button in gridview should have command like this and handle rowcommand event:
<asp:gridview id="CustomersGridView"
datasourceid="CustomersSqlDataSource"
autogeneratecolumns="false"
onrowcommand="CustomersGridView_RowCommand"
runat="server">
<columns>
<asp:buttonfield buttontype="Button"
commandname="Select"
headertext="Select Customer"
text="Select"/>
</columns>
</asp:gridview>
To save some time the rules you add to your .gitignore can be used for removing multiple files/folders i.e.
git rm --cached app/**/*.xml
or
git rm --cached -r app/widgets/yourfolder/
e.t.c.
Ok, if it doesn't matter which value in the non-duplicated column you select, this should be pretty easy:
dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))
> dat[!duplicated(dat[,c('id','id2')]),]
id id2 somevalue
1 1 1 x
3 3 4 z
Inside the duplicated
call, I'm simply passing only those columns from dat
that I don't want duplicates of. This code will automatically always select the first of any ambiguous values. (In this case, x.)
Change the Foreign key name in MySQL. You can not have the same foreign key names in the database tables.
Check all your tables and all your foreign keys and avoid having two foreign keys with the same exact name.
I could do this (demo):
<!doctype html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
</head>
<body>
<form >
<input type="file" id="f" data-max-size="32154" />
<input type="submit" />
</form>
<script>
$(function(){
$('form').submit(function(){
var isOk = true;
$('input[type=file][data-max-size]').each(function(){
if(typeof this.files[0] !== 'undefined'){
var maxSize = parseInt($(this).attr('max-size'),10),
size = this.files[0].size;
isOk = maxSize > size;
return isOk;
}
});
return isOk;
});
});
</script>
</body>
</html>
"+" does not mutate the list
.append() mutates the old list
The this-operator can simplify your life:
var Y = function(f) {
return (function(g) {
return g(g);
})(function(h) {
return function() {
return f.apply(h(h), arguments);
};
});
};
Then you avoid the extra function:
var fac = Y(function(n) {
return n == 0 ? 1 : n * this(n - 1);
});
Finally, you call fac(5)
.
You are doing everything right by using a to_date function and specifying the time. The time is there in the database. The trouble is just that when you select a column of DATE datatype from the database, the default format mask doesn't show the time. If you issue a
alter session set nls_date_format = 'dd/MON/yyyy hh24:mi:ss'
or something similar including a time component, you will see that the time successfully made it into the database.
Even though the above solutions do work,This answer is for you in case you want to reverse the clock instead of undoing a git pull.I mean if you want to get your exact repo the way it was X
Mins back then run the command
git reset --hard branchName@{"X Minutes ago"}
Note: before you actually go ahead and run this command please only try this command if you are sure about the time you want to go back to and heres about my situation.
I was currently on a branch develop
, I was supposed to checkout to a new branch and pull in another branch lets say Branch A
but I accidentally ran
git pull origin B
before checking out.
so to undo this change I tried this command
git reset --hard develop@{"10 Minutes ago"}
if you are on windows cmd and get error: unknown switch `e
try adding quotes like this
git reset --hard 'develop@{"10 Minutes ago"}'
If you dont need a feedback about the requested data and also dont need any interactivity between the opener and the popup, you can post a hidden form into the popup:
Example:
<form method="post" target="popup" id="formID" style="display:none" action="https://example.com/barcode/generate" >
<input type="hidden" name="packing_slip" value="35592" />
<input type="hidden" name="reference" value="0018439" />
<input type="hidden" name="total_boxes" value="1" />
</form>
<script type="text/javascript">
window.open('about:blank','popup','width=300,height=200')
document.getElementById('formID').submit();
</script>
Otherwise you could use jsonp. But this works only, if you have access to the other Server, because you have to modify the response.
Add !important
rule to display: table
of your .v-center
class.
.v-center {
display:table !important;
border:2px solid gray;
height:300px;
}
Your display property is being overridden by bootstrap to display: block
.
I have discovered that you cannot have conditionals outside of the stored procedure in mysql. This is why the syntax error. As soon as I put the code that I needed between
BEGIN
SELECT MONTH(CURDATE()) INTO @curmonth;
SELECT MONTHNAME(CURDATE()) INTO @curmonthname;
SELECT DAY(LAST_DAY(CURDATE())) INTO @totaldays;
SELECT FIRST_DAY(CURDATE()) INTO @checkweekday;
SELECT DAY(@checkweekday) INTO @checkday;
SET @daycount = 0;
SET @workdays = 0;
WHILE(@daycount < @totaldays) DO
IF (WEEKDAY(@checkweekday) < 5) THEN
SET @workdays = @workdays+1;
END IF;
SET @daycount = @daycount+1;
SELECT ADDDATE(@checkweekday, INTERVAL 1 DAY) INTO @checkweekday;
END WHILE;
END
Just for others:
If you are not sure how to create a routine in phpmyadmin you can put this in the SQL query
delimiter ;;
drop procedure if exists test2;;
create procedure test2()
begin
select ‘Hello World’;
end
;;
Run the query. This will create a stored procedure or stored routine named test2. Now go to the routines tab and edit the stored procedure to be what you want. I also suggest reading http://net.tutsplus.com/tutorials/an-introduction-to-stored-procedures/ if you are beginning with stored procedures.
The first_day function you need is: How to get first day of every corresponding month in mysql?
Showing the Procedure is working Simply add the following line below END WHILE and above END
SELECT @curmonth,@curmonthname,@totaldays,@daycount,@workdays,@checkweekday,@checkday;
Then use the following code in the SQL Query Window.
call test2 /* or whatever you changed the name of the stored procedure to */
NOTE: If you use this please keep in mind that this code does not take in to account nationally observed holidays (or any holidays for that matter).
You must check the certificate hash code.
ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain,
errors) =>
{
var hashString = certificate.GetCertHashString();
if (hashString != null)
{
var certHashString = hashString.ToLower();
return certHashString == "dec2b525ddeemma8ccfaa8df174455d6e38248c5";
}
return false;
};
You can use readlink
on /proc/self/fd/NNN
where NNN is the file descriptor. This will give you the name of the file as it was when it was opened — however, if the file was moved or deleted since then, it may no longer be accurate (although Linux can track renames in some cases). To verify, stat
the filename given and fstat
the fd you have, and make sure st_dev
and st_ino
are the same.
Of course, not all file descriptors refer to files, and for those you'll see some odd text strings, such as pipe:[1538488]
. Since all of the real filenames will be absolute paths, you can determine which these are easily enough. Further, as others have noted, files can have multiple hardlinks pointing to them - this will only report the one it was opened with. If you want to find all names for a given file, you'll just have to traverse the entire filesystem.
You can wrap them in a div and give the div a set width (the width of the widest image + margin maybe?) and then float the divs. Then, set the images to the center of their containing divs. Your margins between images won't be consistent for the differently sized images but it'll lay out much more nicely on the page.
This is the working code for your question.

SQL Server Express editions are limited in some ways - one way is that they don't have the SQL Agent that allows you to schedule jobs.
There are a few third-party extensions that provide that capability - check out e.g.:
Found the answer here - http://mytechead.wordpress.com/2014/01/30/android-create-a-file-and-write-to-external-storage/
It says,
/**
* Method to check if user has permissions to write on external storage or not
*/
public static boolean canWriteOnExternalStorage() {
// get the state of your external storage
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
// if storage is mounted return true
Log.v("sTag", "Yes, can write to external storage.");
return true;
}
return false;
}
and then let’s use this code to actually write to the external storage:
// get the path to sdcard
File sdcard = Environment.getExternalStorageDirectory();
// to this path add a new directory path
File dir = new File(sdcard.getAbsolutePath() + "/your-dir-name/");
// create this directory if not already created
dir.mkdir();
// create the file in which we will write the contents
File file = new File(dir, "My-File-Name.txt");
FileOutputStream os = outStream = new FileOutputStream(file);
String data = "This is the content of my file";
os.write(data.getBytes());
os.close();
And this is it. If now you visit your /sdcard/your-dir-name/ folder you will see a file named - My-File-Name.txt with the content as specified in the code.
PS:- You need the following permission -
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Sub
don't return values and function
s don't have side effects.
Sometimes you want both side effect and return value.
This is easy to be done once you know that VBA passes arguments by default by reference so you can write your code in this way:
Sub getValue(retValue as Long)
...
retValue = 42
End SUb
Sub Main()
Dim retValue As Long
getValue retValue
...
End SUb
For global functions dir()
is the command to use (as mentioned in most of these answers), however this lists both public functions and non-public functions together.
For example running:
>>> import re
>>> dir(re)
Returns functions/classes like:
'__all__', '_MAXCACHE', '_alphanum_bytes', '_alphanum_str', '_pattern_type', '_pickle', '_subx'
Some of which are not generally meant for general programming use (but by the module itself, except in the case of DunderAliases like __doc__
, __file__
ect). For this reason it may not be useful to list them with the public ones (this is how Python knows what to get when using from module import *
).
__all__
could be used to solve this problem, it returns a list of all the public functions and classes in a module (those that do not start with underscores - _
). See
Can someone explain __all__ in Python? for the use of __all__
.
Here is an example:
>>> import re
>>> re.__all__
['match', 'fullmatch', 'search', 'sub', 'subn', 'split', 'findall', 'finditer', 'compile', 'purge', 'template', 'escape', 'error', 'A', 'I', 'L', 'M', 'S', 'X', 'U', 'ASCII', 'IGNORECASE', 'LOCALE', 'MULTILINE', 'DOTALL', 'VERBOSE', 'UNICODE']
>>>
All the functions and classes with underscores have been removed, leaving only those that are defined as public and can therefore be used via import *
.
Note that __all__
is not always defined. If it is not included then an AttributeError
is raised.
A case of this is with the ast module:
>>> import ast
>>> ast.__all__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'ast' has no attribute '__all__'
>>>
Another way to do this is (using Apache Commons
FileUtils
) -
private void printEmptyFileName(final File file) throws IOException {
if (FileUtils.readFileToString(file).trim().isEmpty()) {
System.out.println("File is empty: " + file.getName());
}
}
F4 doesn't always bring me to this panel. Besides, it is often said that a picture is worth a thousand words.
Remember that collections in C# are zero-based (in other words, the first item in a collection is at position zero). If you have two items in your list, and you want to select the last item, use SelectedIndex = 1
.
Try tracert to resolve the hostname. IE you have Ip address 8.8.8.8 so you would use; tracert 8.8.8.8
How does [HttpContext.Current.User] know which usernames exist or do not exist?
Let's look at an example of one way this works. Suppose you are using Forms Authentication and the "OnAuthenticate" event fires. This event occurs "when the application authenticates the current request" (Reference Source).
Up until this point, the application has no idea who you are.
Since you are using Forms Authentication, it first checks by parsing the authentication cookie (usually .ASPAUTH) via a call to ExtractTicketFromCookie
. This calls FormsAuthentication.Decrypt
(This method is public; you can call this yourself!). Next, it calls Context.SetPrincipalNoDemand
, turning the cookie into a user and stuffing it into Context.User
(Reference Source).
give on .view-type
class float:left;
or delete the float:right;
of .view-name
edit: Wrap your div <div class="view-row">
with another div for example <div class="table">
and set the following css :
.table {
display:table;
width:100%;}
You have to use the table structure for correct results.
You can also use matches with regular expression like this:
boolean bool = List.matches("(?i).*SOME STRING HERE.*")
I am working on an application in which we track live route. Passenger wants to show current position of driver and the expected arrival time to reach at his/her location. So I need to add some duration into current time.
So I found the below mentioned way to do the same. We can add any duration(hour,minutes and seconds) in our current time by moment:
var travelTime = moment().add(642, 'seconds').format('hh:mm A');// it will add 642 seconds in the current time and will give time in 03:35 PM format
var travelTime = moment().add(11, 'minutes').format('hh:mm A');// it will add 11 mins in the current time and will give time in 03:35 PM format; can use m or minutes
var travelTime = moment().add(2, 'hours').format('hh:mm A');// it will add 2 hours in the current time and will give time in 03:35 PM format
It fulfills my requirement. May be it can help you.
Based upon your comments - your path
statement has been changed/is incorrect or the path

Starting with version 3.5.0 of Mockito and using the InlineMockMaker
, you can now mock object constructions:
try (MockedConstruction mocked = mockConstruction(A.class)) {
A a = new A();
when(a.check()).thenReturn("bar");
}
Inside the try-with-resources
construct all object constructions are returning a mock.
Or try this one. For me it's working fine:
imageView.setImageDrawable(ContextCompat.getDrawable(this, image));
Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.
Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe
, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.
I have checked all possible solutions including re-installation of JDK, eclipse as it worked for many people but unfortunately it didn't work for me. Also updated main class in pom.xml but it didn't help. It took my sleep away. I was trying different options and suddenly the magic happened when I checked this checkbox. It might be helpful for many people so thought of sharing
if ($profitloss < 0)
{
echo "The profitloss is negative";
}
Edit: I feel like this was too simple an answer for the rep so here's something that you may also find helpful.
In PHP we can find the absolute value of an integer by using the abs()
function. For example if I were trying to work out the difference between two figures I could do this:
$turnover = 10000;
$overheads = 12500;
$difference = abs($turnover-$overheads);
echo "The Difference is ".$difference;
This would produce The Difference is 2500
.
you can do this using ReflectionTestUtils of Spring (org.springframework.test.util.ReflectionTestUtils)
ReflectionTestUtils.invokeMethod(instantiatedObject,"methodName",argument);
Example : if you have a class with a private method square(int x)
Calculator calculator = new Calculator();
ReflectionTestUtils.invokeMethod(calculator,"square",10);
I know this is an old topic, but I think it is still relevant, and would like to share an implementation of an array comparison method which I feel strikes the right balance between performance and elegance.
static bool CollectionEquals<T>(ICollection<T> a, ICollection<T> b, IEqualityComparer<T> comparer = null)
{
return ReferenceEquals(a, b) || a != null && b != null && a.Count == b.Count && a.SequenceEqual(b, comparer);
}
The idea here is to check for all of the early out conditions first, then fall back on SequenceEqual
. It also avoids doing extra branching and instead relies on boolean short-circuit to avoid unecessary execution. I also feel it looks clean and is easy to understand.
Also, by using ICollection
for the parameters, it will work with more than just arrays.
I suspect you did not know that there are different &
escapes in HTML. The W3C you can see the codes. ×
means ×
in HTML code. Use &times
instead.
If you want the text value of a QString object you can use the __str__
property, like this:
>>> a = QtCore.QString("Happy Happy, Joy Joy!")
>>> a
PyQt4.QtCore.QString(u'Happy Happy, Joy Joy!')
>>> a.__str__()
u'Happy Happy, Joy Joy!'
Hope that helps.
Check the URL it should be using https rather than http protocol.
In my case changing http to https in the URL solved it.
The option to make whitespace visible now appears as an option on the View menu, as "Toggle Render Whitespace" in version 1.15.1 of Visual Studio Code.
This is not an ideal solution as you have to manage two ini files however, I managed to work around this on windows by copying the php ini file in mamp from the conf folder to your active php version in the bin folder.
[MAMP INSTALL]\conf\[ACTIVE PHP VERSION]\php.ini
copy to
[MAMP INSTALL]\bin\php\[ACTIVE PHP VERSION]
I know its 3 years too late, but maybe it can help someone else because I haven't found anything like that except for the moment-timezone library, which is not exactly the same as what he's asking for here.
I've done something similar for german timezone, this is a little complex because of daylight saving time and leap years where you have 366 days.
it might need a little work with the "isDaylightSavingTimeInGermany" function while different timezones change on different times the daylight saving time.
anyway, check out this page: https://github.com/zerkotin/german-timezone-converter/wiki
the main methods are: convertLocalDateToGermanTimezone convertGermanDateToLocalTimezone
I've put an effort into documenting it, so it won't be so confusing.
Try TextFX ? TextFX Html Tidy ? Tidy: reindent XML
If you can't try with Eclipse, do right button, source, and correct indent.
This answer comes a little bit late, but I just was in a similar need.
Observing the comments written by @ganaraj in the question, One use case I was in the need of is, passing a classname via a directive attribute to be added to a ng-repeat li tag in the template.
For example, use the directive like this:
<my-directive class2add="special-class" />
And get the following html:
<div>
<ul>
<li class="special-class">Item 1</li>
<li class="special-class">Item 2</li>
</ul>
</div>
The solution found here applied with templateUrl, would be:
app.directive("myDirective", function() {
return {
template: function(element, attrs){
return '<div><ul><li ng-repeat="item in items" class="'+attrs.class2add+'"></ul></div>';
},
link: function(scope, element, attrs) {
var list = element.find("ul");
}
}
});
Just tried it successfully with AngularJS 1.4.9.
Hope it helps.
I have written a quick guide on how to install the latest versions of Python 2 and Python 3 on CentOS 6 and CentOS 7. It currently covers Python 2.7.13 and Python 3.6.0:
# Start by making sure your system is up-to-date:
yum update
# Compilers and related tools:
yum groupinstall -y "development tools"
# Libraries needed during compilation to enable all features of Python:
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel
# If you are on a clean "minimal" install of CentOS you also need the wget tool:
yum install -y wget
The next steps depend on the version of Python you're installing.
For Python 2.7.14:
wget http://python.org/ftp/python/2.7.14/Python-2.7.14.tar.xz
tar xf Python-2.7.14.tar.xz
cd Python-2.7.14
./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
# Strip the Python 2.7 binary:
strip /usr/local/lib/libpython2.7.so.1.0
For Python 3.6.3:
wget http://python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
tar xf Python-3.6.3.tar.xz
cd Python-3.6.3
./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
# Strip the Python 3.6 binary:
strip /usr/local/lib/libpython3.6m.so.1.0
To install Pip:
# First get the script:
wget https://bootstrap.pypa.io/get-pip.py
# Then execute it using Python 2.7 and/or Python 3.6:
python2.7 get-pip.py
python3.6 get-pip.py
# With pip installed you can now do things like this:
pip2.7 install [packagename]
pip2.7 install --upgrade [packagename]
pip2.7 uninstall [packagename]
You are not supposed to change the system version of Python because it will break the system (as you found out). Installing other versions works fine as long as you leave the original system version alone. This can be accomplished by using a custom prefix (for example /usr/local
) when running configure, and using make altinstall
(instead of the normal make install
) when installing your build of Python.
Having multiple versions of Python available is usually not a big problem as long as you remember to type the full name including the version number (for example "python2.7" or "pip2.7"). If you do all your Python work from a virtualenv the versioning is handled for you, so make sure you install and use virtualenv!
I had a similar issue and ended up with this:
For me this has the advantage that data and annotation are not overlapping.
from matplotlib import pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111)
A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54
plt.plot(A,B)
# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
x = A[ind]
y = B[ind]
xPos = x1 + .02 * (x1 - x0)
yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
ax.annotate('',#label,
xy=(x, y), xycoords='data',
xytext=(xPos, yPos), textcoords='data',
arrowprops=dict(
connectionstyle="arc3,rad=0.",
shrinkA=0, shrinkB=10,
arrowstyle= '-|>', ls= '-', linewidth=2
),
va='bottom', ha='left', zorder=19
)
ax.text(xPos + .01 * (x1 - x0), yPos,
'({:.2f}, {:.2f})'.format(x,y),
transform=ax.transData, va='center')
plt.grid()
plt.show()
Using the text argument in .annotate
ended up with unfavorable text positions.
Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.
SQL Server allows you to join tables from different databases as long as those databases are on the same server. The join syntax is the same; the only difference is that you must fully specify table names.
Let's suppose you have two databases on the same server - Db1
and Db2
. Db1
has a table called Clients
with a column ClientId
and Db2
has a table called Messages
with a column ClientId
(let's leave asside why those tables are in different databases).
Now, to perform a join on the above-mentioned tables you will be using this query:
select *
from Db1.dbo.Clients c
join Db2.dbo.Messages m on c.ClientId = m.ClientId
To specifically answer a part of your question "Is there any situation in which it would be better to use one or the other?", consider a form with repeating sections. If the repeating section contains many select
tags, then the option
s must be rendered for each select, for every row.
In such a case, I would consider using datalist
with input
, because the same datalist
can be used for any number of input
s. This could potentially save a large amount of rendering time on the server, and would scale much better to any number of rows.
You are looking for System.Environment.NewLine
.
On Windows, this is equivalent to \r\n
though it could be different under another .NET implementation, such as Mono on Linux, for example.
If you are using the XmlDocument and XmlNode.
Say:
XmlNode f = root.SelectSingleNode("//form[@id='myform']");
Use:
XmlNode s = f.SelectSingleNode(".//input[@type='submit']");
It depends on the tool that you use. But .// will select any child, any depth from a reference node.
I don't know of anyway to step through the execution of a .bat file but you can use echo
and pause
to help with debugging.
ECHO
Will echo a message in the batch file. Such as ECHO Hello World will print Hello World on the screen when executed. However, without @ECHO OFF at the beginning of the batch file you'll also get "ECHO Hello World" and "Hello World." Finally, if you'd just like to create a blank line, type ECHO. adding the period at the end creates an empty line.PAUSE
Prompt the user to press any key to continue.

command.

The code that others are giving you only replace one occurrence, while using regular expressions replaces them all (like @sorgit said). To replace all the "want" with "not want", us this code:
var text = "this is some sample text that i want to replace";
var new_text = text.replace(/want/g, "dont want");
document.write(new_text);
The variable "new_text" will result in being "this is some sample text that i dont want to replace".

Good news, PyDrive has first class support on CoLab! PyDrive is a wrapper for the Google Drive python client. Here is an example on how you would download ALL files from a folder, similar to using glob
+ *
:
!pip install -U -q PyDrive
import os
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials
# 1. Authenticate and create the PyDrive client.
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)
# choose a local (colab) directory to store the data.
local_download_path = os.path.expanduser('~/data')
try:
os.makedirs(local_download_path)
except: pass
# 2. Auto-iterate using the query syntax
# https://developers.google.com/drive/v2/web/search-parameters
file_list = drive.ListFile(
{'q': "'1SooKSw8M4ACbznKjnNrYvJ5wxuqJ-YCk' in parents"}).GetList()
for f in file_list:
# 3. Create & download by id.
print('title: %s, id: %s' % (f['title'], f['id']))
fname = os.path.join(local_download_path, f['title'])
print('downloading to {}'.format(fname))
f_ = drive.CreateFile({'id': f['id']})
f_.GetContentFile(fname)
with open(fname, 'r') as f:
print(f.read())
Notice that the arguments to drive.ListFile
is a dictionary that coincides with the parameters used by Google Drive HTTP API (you can customize the q
parameter to be tuned to your use-case).
Know that in all cases, files/folders are encoded by id's (peep the 1SooKSw8M4ACbznKjnNrYvJ5wxuqJ-YCk) on Google Drive. This requires that you search Google Drive for the specific id corresponding to the folder you want to root your search in.
For example, navigate to the folder "/projects/my_project/my_data"
that
is located in your Google Drive.
See that it contains some files, in which we want to download to CoLab. To get the id of the folder in order to use it by PyDrive, look at the url and extract the id parameter. In this case, the url corresponding to the folder was:
Where the id is the last piece of the url: 1SooKSw8M4ACbznKjnNrYvJ5wxuqJ-YCk.
Not that I know of, because all markdown references I am aware of, like this one, mention:
Cell content must be on one line only
You can try it with that Markdown Tables Generator (whose example looks like the one you mention in your question, so you may be aware of it already).
If you are using Pandoc’s markdown (which extends John Gruber’s markdown syntax on which the GitHub Flavored Markdown is based) you can use either grid_tables
:
+---------------+---------------+--------------------+ | Fruit | Price | Advantages | +===============+===============+====================+ | Bananas | $1.34 | - built-in wrapper | | | | - bright color | +---------------+---------------+--------------------+ | Oranges | $2.10 | - cures scurvy | | | | - tasty | +---------------+---------------+--------------------+
or multiline_tables
.
------------------------------------------------------------- Centered Default Right Left Header Aligned Aligned Aligned ----------- ------- --------------- ------------------------- First row 12.0 Example of a row that spans multiple lines. Second row 5.0 Here's another one. Note the blank line between rows. -------------------------------------------------------------
