The SmtpClient can be used by code:
SmtpClient mailer = new SmtpClient();
mailer.Host = "mail.youroutgoingsmtpserver.com";
mailer.Credentials = new System.Net.NetworkCredential("yourusername", "yourpassword");
An unhandled exception will (assuming it's repeatable like bad data as opposed to read errors from a particular data node) eventually fail the job anyway.
You can configure the maximum number of times a particular map or reduce task can fail before the entire job fails through the following properties:
mapred.map.max.attempts
- The maximum number of attempts per map task. In other words, framework will try to execute a map task these many number of times before giving up on it.mapred.reduce.max.attempts
- Same as above, but for reduce tasksIf you want to fail the job out at the first failure, set this value from its default of 4 to 1.
You don't tend to execute the make file itself, rather you execute make
, giving it the make file as an argument:
make -f pax.mk
If your make file is actually one of the standard names (like makefile
or Makefile
), you don't even need to specify it. It'll be picked up by default (if you have more than one of these standard names in your build directory, you better look up the make
man page to see which takes precedence).
I added TO_DATE
and it resolved issue.
Before modification - due to below condition i got this error
record_update_dt>='05-May-2017'
After modification - after adding to_date
, issue got resolved.
record_update_dt>=to_date('05-May-2017','DD-Mon-YYYY')
There are certain circumstances in which even fatal errors should be caught (you might need to do some clean up before exiting gracefully and don’t just die..).
I have implemented a pre_system hook in my CodeIgniter applications so that I can get my fatal errors through emails, and this helped me finding bugs that were not reported (or were reported after they were fixed, as I already knew about them :)).
Sendemail checks if the error has already been reported so that it does not spam you with known errors multiple times.
class PHPFatalError {
public function setHandler() {
register_shutdown_function('handleShutdown');
}
}
function handleShutdown() {
if (($error = error_get_last())) {
ob_start();
echo "<pre>";
var_dump($error);
echo "</pre>";
$message = ob_get_clean();
sendEmail($message);
ob_start();
echo '{"status":"error","message":"Internal application error!"}';
ob_flush();
exit();
}
}
Microsoft is moving away from software and database diagramming using Visio and instead transitioning into Visual Studio. See the "Modeling" Projects. Component Diagrams, Sequence Diagrams, Use Cases, Layer Diagrams are all part of the modeling project. While I am experimenting with it (but question its viability), you can generate code from the models creating in the code generation sense.

Adding an answer that exclusively uses the pandas library to read in a .csv file and save as a .xlsx file. This example makes use of pandas.read_csv
(Link to docs) and pandas.dataframe.to_excel
(Link to docs).
The fully reproducible example uses numpy to generate random numbers only, and this can be removed if you would like to use your own .csv file.
import pandas as pd
import numpy as np
# Creating a dataframe and saving as test.csv in current directory
df = pd.DataFrame(np.random.randn(100000, 3), columns=list('ABC'))
df.to_csv('test.csv', index = False)
# Reading in test.csv and saving as test.xlsx
df_new = pd.read_csv('test.csv')
writer = pd.ExcelWriter('test.xlsx')
df_new.to_excel(writer, index = False)
writer.save()

You can do it this way:
=IF(E9>21,"Text 1",IF(AND(E9>=5,E9<=21),"Test 2","Text 3"))
Note I assume you meant >=
and <=
here since your description skipped the values 5
and 21
, but you can adjust these inequalities as needed.
Or you can do it this way:
=IF(E9>21,"Text 1",IF(E9<5,"Text 3","Text 2"))
You can easily convert the string data type to numerical data type.
Don't forget to change collectionName & FieldName.
for ex : CollectionNmae : Users & FieldName : Contactno.
Try this query..
db.collectionName.find().forEach( function (x) {
x.FieldName = parseInt(x.FieldName);
db.collectionName.save(x);
});
If you have a github account and don't want to download software, you can export to github, then download a zip from github.
Here's an example using Guzzle:

* 'access_type' => 'offline',
* )
*/
public static function tokenInfo($accessToken) {
if(!strlen($accessToken)) {
return false;
}
if($accessToken[0] === '{') {
$accessToken = json_decode($accessToken)->access_token;
}
$guzzle = new \GuzzleHttp\Client();
try {

} catch(ClientException $ex) {
return false;
}
return $resp->json();
}
For gcc you want to omit any -O1 -O2 or -O3 options passed to the compiler or if you already have them you can append the -O0 option to turn it off again. It might also help you to add -g for debug so that you can see the c source and disassembled machine code in your debugger.

The best way to get number of rows from resultset is using count function query for database access and then rs.getInt(1) method to get number of rows. from my code look it:
String query = "SELECT COUNT() FROM table";
ResultSet rs = new DatabaseConnection().selectData(query);
rs.getInt(1);
this will return int value number of rows fetched from database. Here DatabaseConnection().selectData() is my code for accessing database. I was also stuck here but then solved...
Let's not make things any more difficult than they need to be. I've come across so many snippets of code that allow you to drag a form around (or another Control). And many of them have their own drawbacks/side effects. Especially those ones where they trick Windows into thinking that a Control on a form is the actual form.
That being said, here is my snippet. I use it all the time. I'd also like to note that you should not use this.Invalidate(); as others like to do because it causes the form to flicker in some cases. And in some cases so does this.Refresh. Using this.Update, I have not had any flickering issues:
private bool mouseDown;
private Point lastLocation;
private void Form1_MouseDown(object sender, MouseEventArgs e)
{
mouseDown = true;
lastLocation = e.Location;
}
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
if(mouseDown)
{
this.Location = new Point(
(this.Location.X - lastLocation.X) + e.X, (this.Location.Y - lastLocation.Y) + e.Y);
this.Update();
}
}
private void Form1_MouseUp(object sender, MouseEventArgs e)
{
mouseDown = false;
}

I think it would be better to actually bind your listBoxes to a datasource, since it looks like you are adding the same elements to each listbox. A simple example would be something like this:
private List<String> _weight = new List<string>() { "kilogram", "pound" };
private List<String> _height = new List<string>() { "foot", "inch", "meter" };
public Window1()
{
InitializeComponent();
}
private void Weight_Click(object sender, RoutedEventArgs e)
{
listBox1.ItemsSource = _weight;
listBox2.ItemsSource = _weight;
}
private void Height_Click(object sender, RoutedEventArgs e)
{
listBox1.ItemsSource = _height;
listBox2.ItemsSource = _height;
}
Not answering the question, but you can also select by index, where i is the index of the item you wish to select:
var formObj = document.getElementById('myForm');
formObj.leaveCode[i].selected = true;
You can also loop through the items to select by display value with a loop:
for (var i = 0, len < formObj.leaveCode.length; i < len; i++)
if (formObj.leaveCode[i].value == 'xxx') formObj.leaveCode[i].selected = true;
You can use childFragmentManager inside Fragments.
As already stated, enum instances should be uppercase according to the docs on the Oracle website (http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html).
However, while looking through a JavaEE7 tutorial on the Oracle website (http://www.oracle.com/technetwork/java/javaee/downloads/index.html), I stumbled across the "Duke's bookstore" tutorial and in a class (tutorial\examples\case-studies\dukes-bookstore\src\main\java\javaeetutorial\dukesbookstore\components\AreaComponent.java
), I found the following enum definition:
private enum PropertyKeys {
alt, coords, shape, targetImage;
}
According to the conventions, it should have looked like:
public enum PropertyKeys {
ALT("alt"), COORDS("coords"), SHAPE("shape"), TARGET_IMAGE("targetImage");
private final String val;
private PropertyKeys(String val) {
this.val = val;
}
@Override
public String toString() {
return val;
}
}
So it seems even the guys at Oracle sometimes trade convention with convenience.
Just do the following change

All the role granted to the schema will be listed.
Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.
seems you can't find the full path in you localhost by js, but you can hide the fakepath to just show the file name. Use jQuery to get the file input's selected filename without the path
For what it's worth, I eventually gave up on fighting with Web Deploy to get it to do what I wanted (copy deployable files and nothing else), so I scripted it in PowerShell and am really happy with the result. It's much faster than anything I tried through MSBuild/Web Publish, presumably because those methods were still doing things I didn't need.
Here's the gist (literally):
function copy-deployable-web-files($proj_path, $deploy_dir) {
# copy files where Build Action = "Content"
$proj_dir = split-path -parent $proj_path
[xml]$xml = get-content $proj_path
$xml.Project.ItemGroup | % { $_.Content } | % { $_.Include } | ? { $_ } | % {
$from = "$proj_dir\$_"
$to = split-path -parent "$deploy_dir\$_"
if (!(test-path $to)) { md $to }
cp $from $to
}
# copy everything in bin
cp "$proj_dir\bin" $deploy_dir -recurse
}
In my case I'm calling this in a CI environment (TeamCity), but it could easily be hooked into a post-build event as well.
I know this question has an accepted answer, but I feel that it doesn't work in all cases.
For completeness and since I spent too much time on this, here is what we did: we ended up using a function from php.js (which is a pretty nice library for those more familiar with PHP but also doing a little JavaScript every now and then):
http://phpjs.org/functions/strip_tags:535
It seemed to be the only piece of JavaScript code which successfully dealt with all the different kinds of input I stuffed into my application. That is, without breaking it – see my comments about the <script />
tag above.
Many algorithms for converting date to and from numbers are already available in many operating systems.
If it helps anyone, here is what I got working in Python using the Python Requests library instead of CURL.
As explained by @staypuftman above, you will need your API Key and List ID from MailChimp and make sure your API Key suffix and URL prefix (i.e. us5) match.
Python:
#########################################################################################
# To add a single contact to MailChimp (using MailChimp v3.0 API), requires:
# + MailChimp API Key
# + MailChimp List Id for specific list
# + MailChimp API URL for adding a single new contact
#
# Note: the API URL has a 3/4 character location subdomain at the front of the URL string.
# It can vary depending on where you are in the world. To determine yours, check the last
# 3/4 characters of your API key. The API URL location subdomain must match API Key
# suffix e.g. us5, us13, us19 etc. but in this example, us5.
# (suggest you put the following 3 values in 'settings' or 'secrets' file)
#########################################################################################
MAILCHIMP_API_KEY = 'your-api-key-here-us5'
MAILCHIMP_LIST_ID = 'your-list-id-here'
MAILCHIMP_ADD_CONTACT_TO_LIST_URL = 'https://us5.api.mailchimp.com/3.0/lists/' + MAILCHIMP_LIST_ID + '/members/'
# Create new contact data and convert into JSON as this is what MailChimp expects in the API
# I've hardcoded some test data but use what you get from your form as appropriate
new_contact_data_dict = {
"email_address": "[email protected]", # 'email_address' is a mandatory field
"status": "subscribed", # 'status' is a mandatory field
"merge_fields": { # 'merge_fields' are optional:
"FNAME": "John",
"LNAME": "Smith"
}
}
new_contact_data_json = json.dumps(new_contact_data_dict)
# Create the new contact using MailChimp API using Python 'Requests' library
req = requests.post(
MAILCHIMP_ADD_CONTACT_TO_LIST_URL,
data=new_contact_data_json,
auth=('user', MAILCHIMP_API_KEY),
headers={"content-type": "application/json"}
)
# debug info if required - .text and .json also list the 'merge_fields' names for use in contact JSON above
# print req.status_code
# print req.text
# print req.json()
if req.status_code == 200:
# success - do anything you need to do
else:
# fail - do anything you need to do - but here is a useful debug message
mailchimp_fail = 'MailChimp call failed calling this URL: {0}\n' \
'Returned this HTTP status code: {1}\n' \
'Returned this response text: {2}' \
.format(req.url, str(req.status_code), req.text)
I think the easiest way is creating a new XML file. In this case, let's call it "example.xml" in the drawable folder, and put in the follow code:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/blue"
android:state_pressed="true" />
</selector>
But before that you have to set the colors in the colors.xml file, in the values folder, like this:
<resources>
<color name="blue">#0000FF</color>
</resources>
That made, you just set the Button / ImageButton to use the new layout, like this:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/example"
/>
Then when you click that image, it will change to the color set in
<item android:drawable="@color/blue"
android:state_pressed="true" />
giving the feedback that you want...
A "connection reset" error message generally means that the other side has aborted the connection during the attempt to create a connection (the handshake). This has a lot of possible causes. A bug in the JDBC driver, a timeout at the DB side, a restart of the database, the DB being run out of available connections, poor network quality, bad virusscanner/firewall/proxy, etc.
As it happens intermittely, a bug in the JDBC driver can be less or more excluded. Left behind the remaining possible causes. I suggest to start with looking in the logs of the DB server.
$('.select_continent').click(function () {
alert($(this).attr('value'));
});
In Postman latest version(7++) may be there is no Bearer field in Authorization So go to Header tab
select key as Authorization and in value write JWT
Maybe you can try this:
void foo(const char* str)
{
// Do something
}
foo("Hello")
It works for me
I have slightly improved answer, which handles extended CSS definitions like:
background-image: url(http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png), -webkit-linear-gradient(top, rgb(81, 127, 164), rgb(48, 96, 136))
JavaScript code:
var bg = $("div").css("background-image")
bg = bg.replace(/.*\s?url\([\'\"]?/, '').replace(/[\'\"]?\).*/, '')
Result:
"http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png"
just offering this up as a possible solution if you don't think the user will have a negative experience on the obvious change. I simply changed the body's class of overflow to hidden when the mouse was over the target div; then I changed the body's div to hidden overflow when the mouse leaves.
Personally I don't think it looks bad, my code could use toggle to make it cleaner, and there are obvious benefits for making this effect possible without the user being aware. So this is probably the hackish-last-resort answer.
//listen mouse on and mouse off for the button
pxMenu.addEventListener("mouseover", toggleA1);
pxOptContainer.addEventListener("mouseout", toggleA2);
//show / hide the pixel option menu
function toggleA1(){
pxOptContainer.style.display = "flex";
body.style.overflow = "hidden";
}
function toggleA2(){
pxOptContainer.style.display = "none";
body.style.overflow = "hidden scroll";
}
Here is how to integrate CSS star rating into an HTML form without using javascript (only html and css):
CSS:
.txt-center {
text-align: center;
}
.hide {
display: none;
}
.clear {
float: none;
clear: both;
}
.rating {
width: 90px;
unicode-bidi: bidi-override;
direction: rtl;
text-align: center;
position: relative;
}
.rating > label {
float: right;
display: inline;
padding: 0;
margin: 0;
position: relative;
width: 1.1em;
cursor: pointer;
color: #000;
}
.rating > label:hover,
.rating > label:hover ~ label,
.rating > input.radio-btn:checked ~ label {
color: transparent;
}
.rating > label:hover:before,
.rating > label:hover ~ label:before,
.rating > input.radio-btn:checked ~ label:before,
.rating > input.radio-btn:checked ~ label:before {
content: "\2605";
position: absolute;
left: 0;
color: #FFD700;
}
HTML:
<div class="txt-center">
<form>
<div class="rating">
<input id="star5" name="star" type="radio" value="5" class="radio-btn hide" />
<label for="star5">?</label>
<input id="star4" name="star" type="radio" value="4" class="radio-btn hide" />
<label for="star4">?</label>
<input id="star3" name="star" type="radio" value="3" class="radio-btn hide" />
<label for="star3">?</label>
<input id="star2" name="star" type="radio" value="2" class="radio-btn hide" />
<label for="star2">?</label>
<input id="star1" name="star" type="radio" value="1" class="radio-btn hide" />

It is little tricky when you try to combine optional parameter and default value for that parameter. Like this,
func test(param: Int? = nil)
These two are completely opposite ideas. When you have an optional type parameter but you also provide default value to it, it is no more an optional type now since it has a default value. Even if the default is nil, swift simply removes the optional binding without checking what the default value is.
So it is always better not to use nil as default value.
There are two cases in which this error is raised.
Consolidate all your tests in one test.js file & your package json add scripts as:
"scripts": {

npm run api:test

Try something like this:
try {
$w = New-Object net.WebClient
$d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
Write-Host $_.Exception.ToString()
}
The exception is in the $_
variable. You might explore $_
like this:
try {
$w = New-Object net.WebClient
$d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
$_ | fl * -Force
}
I think it will give you all the info you need.
My rule: if there is some data that is not displayed, try to use -force
.
If you know that you always want the string between "my" and "is", then you can always perform the following:
string message = "This is an example string and my data is here";
//Get the string position of the first word and add two (for it's length)
int pos1 = message.IndexOf("my") + 2;
//Get the string position of the next word, starting index being after the first position
int pos2 = message.IndexOf("is", pos1);
//use substring to obtain the information in between and store in a new string
string data = message.Substring(pos1, pos2 - pos1).Trim();
This is the XML optional preamble.
version="1.0"
means that this is the XML standard this file conforms toencoding="utf-8"

# To get the MIDDLE part:
> substr(a, 3, 7)
[1] "ftrig"
>
# To get the RIGHT part:
> substr(a, 5, 10)
[1] "right"
The substr()
function tells you where start and stop substr(x, start, stop)
A tried a slight variation on Luca's answer and it worked for me.
diff file1 file2 | grep ">" | sed 's/^> //g' > diff_file
Note that the searched pattern in sed is a >
followed by a space.
Your code is correct, except you are adding (concatenating) strings, not adding integers. Just change your code into:
function compute() {
if ( $('input[name=type]:checked').val() != undefined ) {
var a = parseInt($('input[name=service_price]').val());
var b = parseInt($('input[name=modem_price]').val());
var total = a+b;
$('#total_price').val(a+b);
}
}
and this should work.

update-java-alternatives
The java
executable is not found with your JAVA_HOME
, it only depends on your PATH
.
update-java-alternatives
is a good way to manage it for the entire system is through:
update-java-alternatives -l
Sample output:
java-7-oracle 1 /usr/lib/jvm/java-7-oracle
java-8-oracle 2 /usr/lib/jvm/java-8-oracle
Choose one of the alternatives:
sudo update-java-alternatives -s java-7-oracle
Like update-alternatives
, it works through symlink management. The advantage is that is manages symlinks to all the Java utilities at once: javac
, java
, javap
, etc.
I am yet to see a JAVA_HOME
effect on the JDK. So far, I have only seen it used in third-party tools, e.g. Maven.
Above, you mean OR not AND. Example of AND: 110 & 011 == 010 which is neither of the things you're looking for.
For OR, just have 2 cases without the break on the 1st. Eg:
case 'a':
case 'A':
// do stuff
break;

and LC_ALL
like this:
$ export LC_ALL="en_US.UTF-8"
$ export LC_CTYPE="en_US.UTF-8"
See excerpt from official documentation for containment
option:
containment
Default:
false
Constrains dragging to within the bounds of the specified element or region.
Multiple types supported:
- Selector: The draggable element will be contained to the bounding box of the first element found by the selector. If no element is found, no containment will be set.
- Element: The draggable element will be contained to the bounding box of this element.
- String: Possible values:
"parent"
,"document"
,"window"
.- Array: An array defining a bounding box in the form
[ x1, y1, x2, y2 ]
.Code examples:
Initialize the draggable with thecontainment
option specified:$( ".selector" ).draggable({ containment: "parent" });
Get or set the
containment
option, after initialization:// Getter var containment = $( ".selector" ).draggable( "option", "containment" ); // Setter $( ".selector" ).draggable( "option", "containment", "parent" );
Newer versions of OpenSSL say BEGIN PRIVATE KEY
because they contain the private key + an OID that identifies the key type (this is known as PKCS8 format). To get the old style key (known as either PKCS1 or traditional OpenSSL format) you can do this:
openssl rsa -in server.key -out server_new.key
Alternately, if you have a PKCS1 key and want PKCS8:
openssl pkcs8 -topk8 -nocrypt -in privkey.pem
Full credit to bchr02 for this answer. However, I had to modify it a bit to catch the scenario for lines that have */
(end of comment) followed by an empty line. The regex was matching the non empty line with */
.
New: (^(\r\n|\n|\r)$)|(^(\r\n|\n|\r))|^\s*$/gm
All I did is add ^
as second character to signify the start of line.
A clean approach I find is by giving an ID
for each radio button and then setting it by using the following statement:
document.getElementById('publicedit').checked = true;
i think this add new property in desired type without having to set a primitive value, like when property defined in class definition
var x = new ExpandoObject();
x.NewProp = default(string)
I have different approach if you want access token and make call to other resource system with access token in header
Spring Security comes with automatic security: oauth2 properties access from application.yml file for every request and every request has SESSIONID which it reads and pull user info via Principal, so you need to make sure inject Principal in OAuthUser and get accessToken and make call to resource server

Due to its folder nesting Windows can’t delete the folder as its name is too long. To solve this, install RimRaf:

They are taking a 'shotgun' approach to referencing the font. The browser will attempt to match each font name with any installed fonts on the user's machine (in the order they have been listed).
In your example "HelveticaNeue-Light"
will be tried first, if this font variant is unavailable the browser will try "Helvetica Neue Light"
and finally "Helvetica Neue"
.
As far as I'm aware "Helvetica Neue"
isn't considered a 'web safe font', which means you won't be able to rely on it being installed for your entire user base. It is quite common to define "serif"
or "sans-serif"
as a final default position.
In order to use fonts which aren't 'web safe' you'll need to use a technique known as font embedding. Embedded fonts do not need to be installed on a user's computer, instead they are downloaded as part of the page. Be aware this increases the overall payload (just like an image does) and can have an impact on page load times.
A great resource for free fonts with open-source licenses is Google Fonts. (You should still check individual licenses before using them.) Each font has a download link with instructions on how to embed them in your website.

Here's some succinct Powershell code to apply new permissions to a folder by modifying it's existing ACL (Access Control List).
# Get the ACL for an existing folder
$existingAcl = Get-Acl -Path 'C:\DemoFolder'
# Set the permissions that you want to apply to the folder
$permissions = $env:username, 'Read,Modify', 'ContainerInherit,ObjectInherit', 'None', 'Allow'
# Create a new FileSystemAccessRule object
$rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permissions
# Modify the existing ACL to include the new rule
$existingAcl.SetAccessRule($rule)
# Apply the modified access rule to the folder
$existingAcl | Set-Acl -Path 'C:\DemoFolder'
Each of the values in the $permissions
variable list pertain to the parameters of this constructor for the FileSystemAccessRule class.

You probably need to do something like :
Paint red = new Paint();
red.setColor(android.graphics.Color.RED);
red.setStyle(Paint.Style.FILL);
And use this color for your path, instead of your ARGB. Make sure the last point of your path ends on the first one, it makes sense also.
Tell me if it works please !
AFAIK there is no way. You should try to avoid this situation by always setting pointers to NULL after freeing memory.
If you are most concerned about code size and/or performance (also for WCET analysis, if you need one), I think this is probably going to be one of the more transparent solutions (for finding and removing elements):
unsigned int l=0, removed=0;
for( unsigned int i=0; i<count; i++ ) {
if( array[i] != to_remove )
array[l++] = array[i];
else
removed++;
}
count -= removed;
On Ubuntu with Apache2 and the deflate module already installed (which it is by default), you can enable deflate gzip compression in two easy steps:
a2enmod deflate
/etc/init.d/apache2 force-reload
And you're away! I found pages I served over my adsl connection loaded much faster.
Edit: As per @GertvandenBerg's comment, this enables gzip compression, not deflate.
The answer about going under "Other Users" was close, but not nearly explicit enough, so I felt the need to add this answer, below.
In Oracle, it will only show you tables that belong to schemas (databases in MS SQL Server) that are owned by the account you are logged in with. If the account owns/has created nothing, you will see nothing, even if you have rights/permissions to everything in the database! (This is contrary to MS SQL Server Management Studio, where you can see anything you have rights on and the owner is always "dbo", barring some admin going in and changing it for some unforeseeable reason.)
The owner will be the only one who will see those tables under "Tables" in the tree. If you do not see them because you are not their owner, you will have to go under "Other Users" and expand each user until you find out who created/owns that schema, if you do not know it, already. It will not matter if your account has permissions to the tables or not, you still have to go under "Other Users" and find that user that owns it to see it, under "Tables"!
One thing that can help you: when you write queries, you actually specify in the nomenclature who that owner is, ex.
Select * from admin.mytable
indicates that "admin" is the user that owns it, so you go under "Other Users > Admin" and expand "Tables" and there it is.
I recommend using a cache-buster in the wsdl url.
In our apps we use a SVN Revision id in the wsdl url so the client immediately knows of changing structures. This works on our app because, everytime we change the server-side, we also need to adjust the client accordingly.
$client = new SoapClient('http://somewhere.com/?wsdl&rev=$Revision$');
This requires svn to be configured properly. Not on all repositories this is enabled by default.
In case you are not responsible for both components (server,client) or you don't use SVN you may find another indicator which can be utilised as a cache-buster in your wsdl url.
I had a similar problem but all answers here didn't help me.
For me the problem was a failing test. If you are doing test driven development than a failing / not implemented test shouldn't break the build. I still want my project to build.
To solve this I added a configuration to surefire so that it ignores a failing test.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>

What's going wrong with what you have? What error do you get, or what result do or don't you get that doesn't match your expectations?
I can see the following issues with that SP, which may or may not relate to your problem:
)
after @BrandName
in your SELECT
(at the end)@CategoryID
or @BrandName
to anything anywhere (they're local variables, but you don't assign values to them)Edit Responding to your comment: The error is telling you that you haven't declared any parameters for the SP (and you haven't), but you called it with parameters. Based on your reply about @CategoryID
, I'm guessing you wanted it to be a parameter rather than a local variable. Try this:
CREATE PROCEDURE AddBrand
@BrandName nvarchar(50),
@CategoryID int
AS
BEGIN
DECLARE @BrandID int
SELECT @BrandID = BrandID FROM tblBrand WHERE BrandName = @BrandName
INSERT INTO tblBrandinCategory (CategoryID, BrandID) VALUES (@CategoryID, @BrandID)
END
You would then call this like this:
EXEC AddBrand 'Gucci', 23
...assuming the brand name was 'Gucci' and category ID was 23.
Alternatively you can use ljust/rjust to make the formatting nicer.
print "%s%s" % (str(count).rjust(10), conv)
or
print str(count).ljust(10), conv
This won't fix branches that already have the code you don't want in them (see below for how to do that), but if they had pulled some-branch and now want it to be clean (and not "ahead" of origin/some-branch) then you simply:
git checkout some-branch # where some-branch can be replaced by any other branch
git branch base-branch -D # where base-branch is the one with the squashed commits
git checkout -b base-branch origin/base-branch # recreating branch with correct commits
Note: You can combine these all by putting && between them
Note2: Florian mentioned this in a comment, but who reads comments when looking for answers?
Note3: If you have contaminated branches, you can create new ones based off the new "dumb branch" and just cherry-pick commits over.
Ex:
git checkout feature-old # some branch with the extra commits
git log # gives commits (write down the id of the ones you want)
git checkout base-branch # after you have already cleaned your local copy of it as above
git checkout -b feature-new # make a new branch for your feature
git cherry-pick asdfasd # where asdfasd is one of the commit ids you want
# repeat previous step for each commit id
git branch feature-old -D # delete the old branch
Now feature-new is your branch without the extra (possibly bad) commits!

pdfunite
is fine to merge entire PDFs. If you want, for example, pages 2-7 from file1.pdf and pages 1,3,4 from file2.pdf, you have to use pdfseparate
to split the files into separate PDFs for each page to give to pdfunite
.
At that point you probably want a program with more options. qpdf
is the best utility I've found for manipulating PDFs. pdftk
is bigger and slower and Red Hat/Fedora don't package it because of its dependency on gcj. Other PDF utilities have Mono or Python dependencies. I found qpdf
produced a much smaller output file than using pdfseparate
and pdfunite
to assemble pages into a 30-page output PDF, 970kB vs. 1,6450 kB. Because it offers many more options, qpdf
's command line is not as simple; the original request to merge file1 and file2 can be performed with
qpdf --empty --pages file1.pdf file2.pdf -- merged.pdf
var token = 'spo';
switch(token){
case ( (token.match(/spo/) )? token : undefined ) :
console.log('MATCHED')
break;;
default:
console.log('NO MATCH')
break;;
}
--> If the match is made the ternary expression returns the original token
----> The original token is evaluated by case
--> If the match is not made the ternary returns undefined
----> Case evaluates the token against undefined which hopefully your token is not.
The ternary test can be anything for instance in your case
( !!~ base_url_string.indexOf('xxx.dev.yyy.com') )? xxx.dev.yyy.com : undefined
===========================================
(token.match(/spo/) )? token : undefined )
is a ternary expression.
The test in this case is token.match(/spo/) which states the match the string held in token against the regex expression /spo/ ( which is the literal string spo in this case ).
If the expression and the string match it results in true and returns token ( which is the string the switch statement is operating on ).
Obviously token === token so the switch statement is matched and the case evaluated
It is easier to understand if you look at it in layers and understand that the turnery test is evaluated "BEFORE" the switch statement so that the switch statement only sees the results of the test.
Probably there are some files inside C:\cygwin\bin called xxxxxmake.exe

I like using Restify for REST services. In my case, I had created a REST service to serve up images and then if an image source returned 404/403, I wanted to return an alternative image. Here's what I came up with combining some of the stuff here:
function processRequest(req, res, next, url) {
var httpOptions = {
hostname: host,
path: url,
port: port,
method: 'GET'
};
var reqGet = http.request(httpOptions, function (response) {
var statusCode = response.statusCode;
// Many images come back as 404/403 so check explicitly
if (statusCode === 404 || statusCode === 403) {
// Send default image if error
var file = 'img/user.png';
fs.stat(file, function (err, stat) {
var img = fs.readFileSync(file);
res.contentType = 'image/png';
res.contentLength = stat.size;
res.end(img, 'binary');
});
} else {
var idx = 0;
var len = parseInt(response.header("Content-Length"));
var body = new Buffer(len);
response.setEncoding('binary');
response.on('data', function (chunk) {
body.write(chunk, idx, "binary");
idx += chunk.length;
});
response.on('end', function () {
res.contentType = 'image/jpg';
res.send(body);
});
}
});
reqGet.on('error', function (e) {
// Send default image if error
var file = 'img/user.png';
fs.stat(file, function (err, stat) {
var img = fs.readFileSync(file);
res.contentType = 'image/png';
res.contentLength = stat.size;
res.end(img, 'binary');
});
});
reqGet.end();
return next();
}

{

You can mark properties with readonly
modifier in your declaration:
export class MyClass {
public static readonly MY_PUBLIC_CONSTANT = 10;
private static readonly myPrivateConstant = 5;
}
From the manual:
Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment.
So you can do (from bash):
FOOBAR=1 make
resulting in a variable FOOBAR
in your Makefile.
I'm not an expert, but I'd assume that enough smart people looked at Java's random number generator over the years. Hence, I'd also assume that random UUIDs are good. So you should really have the theoretical collision probability (which is about 1 : 3 × 10^38 for all possible UUIDs. Does anybody know how this changes for random UUIDs only? Is it 1/(16*4)
of the above?)
From my practical experience, I've never seen any collisions so far. I'll probably have grown an astonishingly long beard the day I get my first one ;)
Abstraction : you'll never buy a "device", but always buy something more specific : iPhone, GSII, Nokia 3310... Here, iPhone, GSII and N3310 are concrete things, device is abstract.
Encapsulation : you've got several devices, all of them have got a USB port. You don't know what kind of printed circuit there's back, you just have to know you'll be able to plug a USB cable into it.
Abstraction is a concept, which is allowed by encapsulation. My example wasn't the best one (there's no real link between the two blocks).
You can do encapsulation without using abstraction, but if you wanna use some abstraction in your projects, you'll need encapsulation.
here's another alternative using vector::assign
:
theVector.assign(theSet.begin(), theSet.end());
if you want to add the data in the increment order inside your associative array you can do this:
$newdata = array (
'wpseo_title' => 'test',
'wpseo_desc' => 'test',
'wpseo_metakey' => 'test'
);
// for recipe
$md_array["recipe_type"][] = $newdata;
//for cuisine
$md_array["cuisine"][] = $newdata;
this will get added to the recipe or cuisine depending on what was the last index.
Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this
array_push($md_array["cuisine"],$newdata);
The replace one liner is great but only works because XX and bar have the same lentgh
A good and general def would be:
def findN(s,sub,N,replaceString="XXX"):
return s.replace(sub,replaceString,N-1).find(sub) - (len(replaceString)-len(sub))*(N-1)
jus do this import { shallow, mount } from "enzyme";
const store = mockStore({
startup: { complete: false }
});
describe("==== Testing App ======", () => {
const setUpFn = props => {
return mount(
<Provider store={store}>
<App />
</Provider>
);
};
let wrapper;
beforeEach(() => {
wrapper = setUpFn();
});
You can simply pass to "default" instead of "ON". Seems more adherent to Apple logic.
(but all the other comments about the use of @obj
remains valid.)
The HTTP status code you return should depend on the type of error that has occurred. If an ID doesn't exist in the database, return a 404; if a user doesn't have enough privileges to make that Ajax call, return a 403; if the database times out before being able to find the record, return a 500 (server error).
jQuery automatically detects such error codes, and runs the callback function that you define in your Ajax call. Documentation: http://api.jquery.com/jQuery.ajax/
Short example of a $.ajax
error callback:
$.ajax({
type: 'POST',
url: '/some/resource',
success: function(data, textStatus) {
// Handle success
},
error: function(xhr, textStatus, errorThrown) {
// Handle error
}
});
In DOS you couldn't use environment variables on the command line, only in batch files, where they used the %
sign as a delimiter. If you wanted a literal %
sign in a batch file, e.g. in an echo
statement, you needed to double it.
This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your %
signs in a .cmd file.
If you don't see the Active Directory, it's because you did not install AD LS Users and Computer Feature. Go to Manage - Add Roles & Features. Within Add Roles and Features Wizard, on Features tab, select Remote Server Administration Tools, select - Role Admininistration Tools - Select AD DS and DF LDS Tools.
After that, you can see the PS Active Directory package.

There are more than a few ways. I'll list them in order of inverted preference (i.e., best first, worst last):
import file
. This is good because it's secure, fast, and maintainable. Code gets reused as it's supposed to be done. Most Python libraries run using multiple methods stretched over lots of files. Highly recommended. Note that if your file is called file.py
, your import
should not include the .py
extension at the end.execfile('file.py')
in Python 2exec(open('file.py').read())
in Python 3os.system('python file.py')
. Use when desperate.I prefer to use date-fns library for date manipulating. It is really great modular and consistent tool. You can get start and end of the day this way:
var startOfDay = dateFns.startOfDay;_x000D_
var endOfDay = dateFns.endOfDay;_x000D_
_x000D_
console.log('start of day ==> ', startOfDay(new Date('2015-11-11')));_x000D_
console.log('end of day ==> ', endOfDay(new Date('2015-11-11')));
_x000D_

, if you upload a file using drag and drop events, you can get the file in drop
event by accessing eventArgs.dataTransfer.files
.
You can get more information with
# Windows
set GIT_CURL_VERBOSE=1
set GIT_TRACE_PACKET=2
# Unix
export GIT_CURL_VERBOSE=1
export GIT_TRACE_PACKET=2
And then try a git push
.
Double-check your proxy settings if you have one.
Note: git 2.8 (March 2016) adds more information on an error 35:

remote-curl
: includecurl_errorstr
on SSL setup failuresFor
curl
error 35 (CURLE_SSL_CONNECT_ERROR
) users need the additional text stored inCURLOPT_ERRORBUFFER
to debug why the connection did not start.
This iscurl_errorstr
inside ofhttp.c
, so include that in the message if it is non-empty.
Also check out the common causes for that message:
If it was working before, and not working today, it is possible the SSL private key has expired on the BitBucket side (see below, reason #3), but that doesn't seem to be the case here (the certificate is valid until 12/03/2014).
Firing off a request like the following, results in the Unknown SSL Protocol error:
curl --sslv2 https://techstacks-tools.appspot.com/
Why? Well, in this case it is because the techstacks tools site does not support SSLv2, thus, generating the curl (35) error.
You could be trying to connect to the site using an ssl cipher that the site is configured to reject.
For example, anonymous ciphers are typically disabled on ssl-encrypted sites that are customer-facing. (Many of us set a blanket rejection policy on any SSL-encrypted web site—regardless of it's purpose.)
The following command string "can" also result in the curl (35) error:
curl --ciphers ADH-RC4-MD5 https://some_web_site.some_domain.com/
Unfortunately, the type of error response you can get from curl depends largely upon the ssl server. On some sites, you'll receive the Unknown SSL Protocol error but on my techstacks-tools site, I get:
curl: (35) error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
Kudos to Google because this particular error is a bit more descriptive than the one my websites at work generate because this at least tells you that a ssl socket was started but because of handshake failures, the socket was never able to complete.
Try connecting to the site with a cipher that the site supports. Not sure which cipher to use? Well, let me introduce my cryptonark ssl cipher tester...
I came across this one earlier today working with an old WebSeAL site.
In IBM GSKit, you can specify how long the private key password is valid. After reaching a certain date, you will still be able to get webseal started and listening on port 443 (or whatever you set your https-port value to) but you will not be able to successfully negotiate an SSL session.
In today's case, the old WebSEAL instance was using long-expired kdb file with a long expired private key password. Once replaced with the correct, more-up-to-date version, everything worked again.
Some ISP's and DNS providers like to intercept your failed DNS queries in order to redirect you to a search engine results-style page offering you alternative URLs or "Did you mean...?" counter-query results.
If you see an error like this:
error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol,
it could be due to you typing the hostname incorrectly or the hostname is not yet tabled in your DNS. You can verify that with a simple "
host
" or "nslookup
".
Note (August 2015): Git 2.6+ (Q3 2015) will allow to specify the SSL version explicitly:

http.sslVersion
The SSL version to use when negotiating an SSL connection, if you want to force the default.
The available and default version depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the 'CURLOPT_SSL_VERSION
' option; see the libcurl documentation for more details on the format of this option and for the ssl version supported.
Actually the possible values of this option are:
- sslv2
- sslv3
- tlsv1
- tlsv1.0
- tlsv1.1
- tlsv1.2
Can be overridden by the '
GIT_SSL_VERSION
' environment variable.
To force git to use libcurl's default ssl version and ignore any explicithttp.sslversion
option, set 'GIT_SSL_VERSION' to the empty string.

Static typing
A programming language is said to use static typing when type checking is performed during compile-time as opposed to run-time. In static typing, types are associated with variables not values. Statically typed languages include Ada, C, C++, C#, JADE, Java, Fortran, Haskell, ML, Pascal, Perl (with respect to distinguishing scalars, arrays, hashes and subroutines) and Scala. Static typing is a limited form of program verification (see type safety): accordingly, it allows many type errors to be caught early in the development cycle. Static type checkers evaluate only the type information that can be determined at compile time, but are able to verify that the checked conditions hold for all possible executions of the program, which eliminates the need to repeat type checks every time the program is executed. Program execution may also be made more efficient (i.e. faster or taking reduced memory) by omitting runtime type checks and enabling other optimizations.
Because they evaluate type information during compilation, and therefore lack type information that is only available at run-time, static type checkers are conservative. They will reject some programs that may be well-behaved at run-time, but that cannot be statically determined to be well-typed. For example, even if an expression always evaluates to true at run-time, a program containing the code
if <complex test> then 42 else <type error>
will be rejected as ill-typed, because a static analysis cannot determine that the else branch won't be taken.[1] The conservative behaviour of static type checkers is advantageous when evaluates to false infrequently: A static type checker can detect type errors in rarely used code paths. Without static type checking, even code coverage tests with 100% code coverage may be unable to find such type errors. Code coverage tests may fail to detect such type errors because the combination of all places where values are created and all places where a certain value is used must be taken into account.
The most widely used statically typed languages are not formally type safe. They have "loopholes" in the programming language specification enabling programmers to write code that circumvents the verification performed by a static type checker and so address a wider range of problems. For example, Java and most C-style languages have type punning, and Haskell has such features as unsafePerformIO: such operations may be unsafe at runtime, in that they can cause unwanted behaviour due to incorrect typing of values when the program runs.
Dynamic typing
A programming language is said to be dynamically typed, or just 'dynamic', when the majority of its type checking is performed at run-time as opposed to at compile-time. In dynamic typing, types are associated with values not variables. Dynamically typed languages include Groovy, JavaScript, Lisp, Lua, Objective-C, Perl (with respect to user-defined types but not built-in types), PHP, Prolog, Python, Ruby, Smalltalk and Tcl. Compared to static typing, dynamic typing can be more flexible (e.g. by allowing programs to generate types and functionality based on run-time data), though at the expense of fewer a priori guarantees. This is because a dynamically typed language accepts and attempts to execute some programs which may be ruled as invalid by a static type checker.
Dynamic typing may result in runtime type errors—that is, at runtime, a value may have an unexpected type, and an operation nonsensical for that type is applied. This operation may occur long after the place where the programming mistake was made—that is, the place where the wrong type of data passed into a place it should not have. This makes the bug difficult to locate.
Dynamically typed language systems, compared to their statically typed cousins, make fewer "compile-time" checks on the source code (but will check, for example, that the program is syntactically correct). Run-time checks can potentially be more sophisticated, since they can use dynamic information as well as any information that was present during compilation. On the other hand, runtime checks only assert that conditions hold in a particular execution of the program, and these checks are repeated for every execution of the program.
Development in dynamically typed languages is often supported by programming practices such as unit testing. Testing is a key practice in professional software development, and is particularly important in dynamically typed languages. In practice, the testing done to ensure correct program operation can detect a much wider range of errors than static type-checking, but conversely cannot search as comprehensively for the errors that both testing and static type checking are able to detect. Testing can be incorporated into the software build cycle, in which case it can be thought of as a "compile-time" check, in that the program user will not have to manually run such tests.

There's also the DateTime class which implements a function for comparison operators.
// $now = new DateTime();
$dtA = new DateTime('05/14/2010 3:00PM');
$dtB = new DateTime('05/14/2010 4:00PM');
if ( $dtA > $dtB ) {

Here you have the angularjs http request to the API that any client will have to do. Just adapt the WS url and params (if you have) to your case. It's a mixture between Naoe's answer and this one:
$http({
url: '/path/to/your/API',
method: 'POST',
params: {},
headers: {
'Content-type': 'application/pdf',
},
responseType: 'arraybuffer'
}).success(function (data, status, headers, config) {
// TODO when WS success
var file = new Blob([data], {
type: 'application/csv'
});
//trick to download store a file having its URL
var fileURL = URL.createObjectURL(file);
var a = document.createElement('a');
a.href = fileURL;
a.target = '_blank';
a.download = 'yourfilename.pdf';
document.body.appendChild(a); //create the link "a"
a.click(); //click the link "a"
document.body.removeChild(a); //remove the link "a"
}).error(function (data, status, headers, config) {
//TODO when WS error
});
Explanation of the code:
/path/to/your/API
.<a>
.<a>
tag, using the JS click()
function<a>
tag, after its click.For Windows Machines, use:
git reset HEAD~1 #Remove Commit Locally
If you want to confirm if focus is with an element then
if ($('#inputId').is(':focus')) {
//your code
}
Amber's answer is correct but I found it unclear; The syntax is:
git blame {commit_id} -- {path/to/file}
Note: the --
is used to separate the tree-ish sha1 from the relative file paths. 1
For example:
git blame master -- index.html
Full credit to Amber for knowing all the things! :)
That error can only be caused by one of three things:
First of all, ensure, what script is call properly, it should looks like
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
and shouldn't have attributes async or defer.
Then you should check the Firebug net panel to see if the file is actually being loaded properly. If not, it will be highlighted red and will say "404" beside it. If the file is loading properly, that means that the issue is number 2.
Make sure all jQuery javascript code is being run inside a code block such as:
$(document).ready(function () {
//your code here
});
This will ensure that your code is being loaded after jQuery has been initialized.
One final thing to check is to make sure that you are not loading any plugins before you load jQuery. Plugins extend the "$" object, so if you load a plugin before loading jQuery core, then you'll get the error you described.
Note: If you're loading code which does not require jQuery to run it does not need to be placed inside the jQuery ready handler. That code may be separated using document.readyState
.
I have a test application set up using JPA/Hibernate & Spring, and my configuration mirrors yours with the exception that I create a datasource and inject it into the EntityManagerFactory, and moved the datasource specific properties out of the persistenceUnit and into the datasource. With these two small changes, my EM gets injected properly.
Try these ...
Option1
window.location=document.referrer;
Option2
window.location.reload(history.back());
Leaving database modeling issues aside. I think you can try
SELECT * FROM STUDENTS WHERE ISNUMERIC(STUDENTID) = 0
But ISNUMERIC
returns 1 for any value that seems numeric including things like -1.0e5
If you want to exclude digit-only studentids, try something like
SELECT * FROM STUDENTS WHERE STUDENTID LIKE '%[^0-9]%'
This Worked for me

My issue was that I left the "mex" onto the end of my web service link.
Instead of "http://yeagertech.com/yeagerte/YeagerTechWcfService.YeagerTechWcfService.svc/mex"
Use "http://yeagertech.com/yeagerte/YeagerTechWcfService.YeagerTechWcfService.svc"
If you use jQuery built-in after()
with empty value it will create a dynamic object that will match your :after
CSS selector.
$('.active').after().click(function () {
alert('clickable!');
});
See the jQuery documentation.
When you want to edit something in Angular you need to insert an ngModel in your html
try this in your sample:
<input type="text" name="abc" class="color" ng-model="myStyle.color">
You don't need to watch the change at all!
Get-ChildItem $originalPath\* -Include @("*.gif", "*.jpg", "*.xls*", "*.doc*", "*.pdf*", "*.wav*", "*.ppt")
I'd like to count the commits too, so here's how to do that:
Count how many commits are on the current branch (HEAD
), but NOT on master
:
git log --oneline ^master HEAD | wc -l
wc -l
means "word count"--count the number of 'l'ines.
And of course to see the whole log messages, as other answers have given:
git log ^master HEAD
...or in a condensed --oneline
form:
git log --oneline ^master HEAD
If you don't want to count merge commits either, you can exclude those with --no-merges
:
git log --oneline --no-merges ^master HEAD | wc -l
etc.
Follow this blog post. You can do it very easily. https://wadsashika.wordpress.com/2015/01/06/manage-remote-mysql-database-locally-using-phpmyadmin/
The file config.inc.php contains the configuration settings for your phpMyAdmin installation. It uses an array to store sets of config options for every server it can connect to and by default there is only one, your own machine, or localhost. In order to connect to another server, you would have to add another set of config options to the config array. You have to edit this configuration file.
First open config.inc.php file held in phpMyAdmin folder. In wamp server, you can find it in wamp\apps\phpmyadmin folder. Then add following part to that file.
$i++;
$cfg['Servers'][$i]['host'] = 'hostname/Ip Adress';
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['compress'] = FALSE;
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'username';
$cfg['Servers'][$i]['password'] = 'password';
Let’s see what is the meaning of this variables.
$i++ :- Incrementing variable for each server
$cfg[‘Servers’][$i][‘host’] :- Server host name or IP adress
$cfg[‘Servers’][$i][‘port’] :- MySQL port (Leave a blank for default port. Default MySQL port is 3306)
$cfg[‘Servers’][$i][‘socket’] :- Path to the socket (Leave a blank for default socket)
$cfg[‘Servers’][$i][‘connect_type’] :- How to connect to MySQL server (‘tcp’ or ‘socket’)
$cfg[‘Servers’][$i][‘extension’] :- php MySQL extension to use (‘mysql’ or ‘msqli’)
$cfg[‘Servers’][$i][‘compress’] :- Use compressed protocol for the MySQL connection (requires PHP >= 4.3.0)
$cfg[‘Servers’][$i][‘auth_type’] :- Method of Authentication
$cfg[‘Servers’][$i][‘username’] :- Username to the MySQL database in remote server
$cfg[‘Servers’][$i][‘password’] :- Password to the MySQL database int he remote server
After adding this configuration part, restart you server and now your phpMyAdmin home page will change and it will show a field to select the server.
Now you can select you server and access your remote database by entering username and password for that database.
Just put a line break into your text.
You don't add lines as a method. Multiline just supports the use of line breaks.
Answering another for Simplicity & readability.
Also, editing existing predefined class members with new methods is not encouraged:
function getDateInYYYYMMDD() {
let currentDate = new Date();
// year
let yyyy = '' + currentDate.getFullYear();
// month
let mm = ('0' + (currentDate.getMonth() + 1)); // prepend 0 // +1 is because Jan is 0
mm = mm.substr(mm.length - 2); // take last 2 chars
// day
let dd = ('0' + currentDate.getDate()); // prepend 0
dd = dd.substr(dd.length - 2); // take last 2 chars
return yyyy + "" + mm + "" + dd;
}
var currentDateYYYYMMDD = getDateInYYYYMMDD();
console.log('currentDateYYYYMMDD: ' + currentDateYYYYMMDD);
Both C# and Java don't have plain functions only member functions (aka methods). And the methods are not first-class citizens. First-class functions allow us to create beautiful and powerful code, as seen in F# or Clojure languages. (For instance, first-class functions can be passed as parameters and can return functions.) Java and C# ameliorate this somewhat with interfaces/delegates.
Func<int, int, int> randInt = (n1, n2) => new Random().Next(n1, n2);
So, Func
is a built-in delegate which brings some functional programming features and helps reduce code verbosity.
There are multiple ways to do this and from your question it's nor clear what you need.
1. If you need environment variable to be defined PER TASK ONLY, you do this:
- hosts: dev tasks: - name: Echo my_env_var shell: "echo $MY_ENV_VARIABLE" environment: MY_ENV_VARIABLE: whatever_value - name: Echo my_env_var again shell: "echo $MY_ENV_VARIABLE"
Note that MY_ENV_VARIABLE
is available ONLY for the first task, environment
does not set it permanently on your system.
TASK: [Echo my_env_var] *******************************************************
changed: [192.168.111.222] => {"changed": true, "cmd": "echo $MY_ENV_VARIABLE", ... "stdout": "whatever_value"}
TASK: [Echo my_env_var again] *************************************************
changed: [192.168.111.222] => {"changed": true, "cmd": "echo $MY_ENV_VARIABLE", ... "stdout": ""}
Hopefully soon using environment
will also be possible on play level, not only task level as above.
There's currently a pull request open for this feature on Ansible's GitHub: https://github.com/ansible/ansible/pull/8651
UPDATE: It's now merged as of Jan 2, 2015.
2. If you want permanent environment variable + system wide / only for certain user
You should look into how you do it in your Linux distribution / shell, there are multiple places for that. For example in Ubuntu you define that in files like for example:
~/.profile
/etc/environment
/etc/profile.d
directoryYou will find Ubuntu docs about it here: https://help.ubuntu.com/community/EnvironmentVariables
After all for setting environment variable in ex. Ubuntu you can just use lineinfile
module from Ansible and add desired line to certain file. Consult your OS docs to know where to add it to make it permanent.
I like the simple solution using windows functions:
select t.*
from (select student.*, su.subname, max(mark) over (partition by subid) as maxmark
from marks m join
students st
on m.stid = st.stid join
subject su
on m.subid = su.subid
) t
where t.mark = maxmark
Or, alternatively:
select t.*
from (select student.*, su.subname, rank(mark) over (partition by subid order by mark desc) as markseqnum
from marks m join
students st
on m.stid = st.stid join
subject su
on m.subid = su.subid
) t
where markseqnum = 1
Use FOR XML PATH('')
- which is converting the entries to a comma separated string and STUFF() -which is to trim the first comma- as follows Which gives you the same comma separated result
SELECT STUFF((SELECT ',' + INSTITUTIONNAME
FROM EDUCATION EE
WHERE EE.STUDENTNUMBER=E.STUDENTNUMBER
ORDER BY sortOrder
FOR XML PATH('')), 1, 1, '') AS listStr
FROM EDUCATION E
GROUP BY E.STUDENTNUMBER
Here is the FIDDLE
Just escape the "\"
by using + "\\Tasks"
or use a verbatim string like @"\Tasks"
If you want really independance from the filesystem attributes and from the bit-level differences of some tar versions, you could use cpio:
cpio -i -e theDirname | md5sum
Your code should be contain WHILE
before group by
and having
:
SELECT Email, COUNT(*)
FROM user_log
WHILE Email IS NOT NULL
GROUP BY Email
HAVING COUNT(*) > 1
ORDER BY UpdateDate DESC
The equivalent of offsetHeight and offsetWidth in jQuery is $(window).width(), $(window).height() It's not the clientHeight and clientWidth
For Windows, I've created a build.cmd
file:
(replace the keystore path and alias)
For Cordova:
@echo off
set /P spassw="Store Password: " && set /P kpassw="Key Password: " && cordova build android --release -- --keystore=../../local/my.keystore --storePassword=%spassw% --alias=tmpalias --password=%kpassw%
And for Ionic:
@echo off
set /P spassw="Store Password: " && set /P kpassw="Key Password: " && ionic build --prod && cordova build android --release -- --keystore=../../local/my.keystore --storePassword=%spassw% --alias=tmpalias --password=%kpassw%
Save it in the ptoject's directory, you can double click or open it with cmd.
If you use a hash table instead of either adjacency matrix or list, you'll get better or same big-O run-time and space for all operations (checking for an edge is O(1)
, getting all adjacent edges is O(degree)
, etc.).
There's some constant factor overhead though for both run-time and space (hash table isn't as fast as linked list or array lookup, and takes a decent amount extra space to reduce collisions).
Following width worked well in HTML5: -
<table >

<th style="min-width:60px">Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
<tr>
<td>February</td>
<td>$80</td>
</tr>
</table>
Please note that
If you have Pillow
installed with scipy
and it is still giving you error then check your scipy
version because it has been removed from scipy since 1.3.0rc1
.
rather install scipy 1.1.0
by :
pip install scipy==1.1.0
check https://github.com/scipy/scipy/issues/6212
The method imread
in scipy.misc
requires the forked package of PIL
named Pillow
. If you are having problem installing the right version of PIL try using imread
in other packages:
from matplotlib.pyplot import imread
im = imread(image.png)
To read jpg
images without PIL
use:
import cv2 as cv
im = cv.imread(image.jpg)
You can try
from scipy.misc.pilutil import imread
instead of from scipy.misc import imread

If you see below error message, when try into phpyAdmin
:
New XAMPP security concept:
Access to the requested directory is only available from the local network.
This setting can be configured in the file "httpd-xampp.conf".
You can do next (for XAMPP, deployed on the UNIX-system):
You can try change configuration for <Directory "/opt/lampp/phpmyadmin">
# vi /opt/lampp/etc/extra/httpd-xampp.conf
and change security settings to
#LoadModule perl_module modules/mod_perl.so
<Directory "/opt/lampp/phpmyadmin">

margin: 15px 15px;
-webkit-box-shadow: 2px 3px 8px #eee;
-moz-box-shadow: 2px 3px 8px #eee;
box-shadow: 2px 3px 8px #eee;
box-shadow requires you to set the horizontal & vertical offsets, you can then optionally set the blur and colour, you can also choose to have the shadow inset instead of the default outset. Colour can be defined as hex or rgba.
box-shadow : inset/outset h-offset v-offset blur spread color;
Explanation of the values...
inset/outset -- whether the shadow is inside or outside the box. If not specified it will default to outset.
h-offset -- the horizontal offset of the shadow (required value)
v-offset -- the vertical offset of the shadow (required value)
blur -- as it says, the blur of the shadow
spread -- moves the shadow away from the box equally on all sides. A positive value causes the shadow to expand, negative causes it to contract. Though this value isn't often used, it is useful with multiple shadows.
color -- as it says, the color of the shadow
box-shadow:2px 3px 8px #eee; a gray shadow with a horizontal outset of 2px, vertical of 3px and a blur of 8px
For AngularJs you have to use "angular-datatables.min.js" file for datatable settings. You will get this from http://l-lin.github.io/angular-datatables/#/welcome.
After that you can write code like below,

</script>
<div ng-app="AngularWayApp" ng-controller="AngularWayCtrl">
<table id="example" datatable="ng" class="table">

For people who are using Ionic/Cordova framework, we need to change the distributionUrl
in GradleBuilder.js
file to var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-2.10-all.zip';
The GradleBuilder.js
locates at project/platforms/android/cordova/lib/builders/GradleBuilder.js
I don't know if this was "the" official use case, but the following produces a warning in Java (that can further produce compile errors if mixed with return
statements, leading to unreachable code):
while (1 == 2) { // Note that "if" is treated differently
System.out.println("Unreachable code");
}
However this is legal:
while (isUserAGoat()) {
System.out.println("Unreachable but determined at runtime, not at compile time");
}
So I often find myself writing a silly utility method for the quickest way to dummy out a code block, then in completing debugging find all calls to it, so provided the implementation doesn't change this can be used for that.
JLS points out if (false)
does not trigger "unreachable code" for the specific reason that this would break support for debug flags, i.e., basically this use case (h/t @auselen). (static final boolean DEBUG = false;
for instance).
I replaced while
for if
, producing a more obscure use case. I believe you can trip up your IDE, like Eclipse, with this behavior, but this edit is 4 years into the future, and I don't have an Eclipse environment to play with.

the problem is in flow annotation in handleClick, i removed this and works fine thanks @alik
Back with .Net 1.1 obfuscation was essential: decompiling code was easy, and you could go from assembly, to IL, to C# code and have it compiled again with very little effort.
Now with .Net 3.5 I'm not at all sure. Try decompiling a 3.5 assembly; what you get is a long long way from compiling.
Add the optimisations from 3.5 (far better than 1.1) and the way anonymous types, delegates and so on are handled by reflection (they are a nightmare to recompile). Add lambda expressions, compiler 'magic' like Linq-syntax and var
, and C#2 functions like yield
(which results in new classes with unreadable names). Your decompiled code ends up a long long way from compilable.
A professional team with lots of time could still reverse engineer it back again, but then the same is true of any obfuscated code. What code they got out of that would be unmaintainable and highly likely to be very buggy.
I would recommend key-signing your assemblies (meaning if hackers can recompile one they have to recompile all) but I don't think obfuscation's worth it.
It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.
Look at the definition of sys.all_parameters
:
default_value
sql_variant
Ifhas_default_value
is 1, the value of this column is the value of the default for the parameter; otherwise,NULL
.
That is, whatever the default for a parameter is, it has to fit in that column.
As Alex K pointed out in the comments, you can just do:
CREATE PROCEDURE [dbo].[problemParam]
@StartDate INT = NULL,
@EndDate INT = NULL
AS
BEGIN
SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))
provided that NULL
isn't intended to be a valid value for @StartDate
.
As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE()
within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.
Have you tried to change in Tortoise Settings the status cache to 'Default'? I had this problem with the overlay icon on folders because I had this option in 'Shell'. The option is in Settings -> Icons overlay.
Maybe this could help you http://tortoisesvn.net/node/97
bash -n scriptname
Perhaps an obvious caveat: this validates syntax but won't check if your bash script tries to execute a command that isn't in your path, like ech hello
instead of echo hello
.
An example to help you get off the ground.
for f in *.jpg; do mv "$f" "$(echo "$f" | sed s/IMG/VACATION/)"; done
In this example, I am assuming that all your image files contain the string IMG
and you want to replace IMG
with VACATION
.
The shell automatically evaluates *.jpg
to all the matching files.
The second argument of mv
(the new name of the file) is the output of the sed
command that replaces IMG
with VACATION
.
If your filenames include whitespace pay careful attention to the "$f"
notation. You need the double-quotes to preserve the whitespace.
you can use this too
.parent:hover * {
/* ... */
}

You are creating a set
via set(...)
call, and set
needs hashable items. You can't have set of lists. Because list's arent hashable.
[[(a,b) for a in range(3)] for b in range(3)]
is a list. It's not a hashable type. The __hash__
you saw in dir(...) isn't a method, it's just None.
A list comprehension returns a list, you don't need to explicitly use list there, just use:
>>> [[(a,b) for a in range(3)] for b in range(3)]
[[(0, 0), (1, 0), (2, 0)], [(0, 1), (1, 1), (2, 1)], [(0, 2), (1, 2), (2, 2)]]
Try those:
>>> a = {1, 2, 3}
>>> b= [1, 2, 3]
>>> type(a)
<class 'set'>
>>> type(b)
<class 'list'>
>>> {1, 2, []}
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'
>>> print([].__hash__)
None
>>> [[],[],[]] #list of lists
[[], [], []]
>>> {[], [], []} #set of lists
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'list'
Paste it into your web page, just before the closing
</head>
tag.One of the main advantages of the asynchronous snippet is that you can position it at the top of the HTML document. This increases the likelihood that the tracking beacon will be sent before the user leaves the page. It is customary to place JavaScript code in the
<head>
section, and we recommend placing the snippet at the bottom of the<head>
section for best performance
You can use
LEFT(column, length)
or
SUBSTRING(column, start index, length)
If you have data already present in both the tables and you want to update a table column values based on some condition then use this
UPDATE Table1 set Name=(select t2.Name from Table2 t2 where t2.id=Table1.id)
select into
is used in pl/sql to set a variable to field values. Instead, use
create table new_table as select * from old_table
Update: If you are using a newer version of MVC, the same process applies, just be sure to use the correct version number in the web.config's <host>
line.
Well, I found myself experiencing the same thing you did, and after a bit further research, I found out what the problem is!
You need to include the default MVC3 web.config for the Views folder. MVC3 has two: one in the root for your application, and one for the views folder. This has a section for included namespaces. Be sure that yours looks something like this:
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
</namespaces>
</pages>
</system.web.webPages.razor>
I suggest that you create a new MVC3 project, then just copy the web.config created for you into your views folder.
Important Once you've done that, you need to close the file and reopen it. Voila! Intellisense!
Example how to run program and write stdout and stderr to file with timestamp:
cmd /c ""C:\Program Files (x86)\program.exe" -param fooo >> "c:\dir space\Log_%date:~10,4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.txt" 2>&1"
Key part is to double quote whole part behind cmd /c
and inside it use double quotes as usual. Also note that date is locale dependent, this example works using US locale.
Another way is to use an array as a type, e.g.:
Video[] videoArray = gson.fromJson(json, Video[].class);
This way you avoid all the hassle with the Type object, and if you really need a list you can always convert the array to a list, e.g.:
List<Video> videoList = Arrays.asList(videoArray);
IMHO this is much more readable.
In Kotlin this looks like this:
Gson().fromJson(jsonString, Array<Video>::class.java)
To convert this array into List, just use .toList()
method
Web Services - that's standard defined by W3C, so they can be accessed semi-automatically or automatically (WSDL / UDDI). The whole thing is based on XML, so anyone can call it. And every aspect of the service is very well defined. There's parameters description standard, parameter passing standard, response standard, discovery standard, etc. etc. You could probably write 2000 pages book that'd describe the standard. There are even some "additional" standards for doing "standard" things, like authentication.
Despite the fact that automatic invoking and discovery is barely working because clients are rather poor, and you have no real guarantee that any service can be called from any client.
Web API is typically done as HTTP/REST, nothing is defined, output can be for eg. JSON/XML, input can be XML/JSON/or plain data. There are no standards for anything => no automatic calling and discovery. You can provide some description in text file or PDF, you can return the data in Windows-1250 instead of unicode, etc. For describing the standard it'd be 2 pages brochure with some simple info and you'll define everything else.
Web is switching towards Web API / REST. Web Services are really no better than Web API. Very complicated to develop and they eat much more resources (bandwidth and RAM)... and because of all data conversions (REQUEST->XML->DATA->RESPONSE->XML->VALIDATION->CONVERSION->DATA) are very slow.
Eg. In WebAPI you can pack the data, send it compressed and un-compress+un-pack on the client. In SOAP you could only compress HTML request.
You can use the sort
command:
sort -k2 -n yourfile
-n
,--numeric-sort
compare according to string numerical value
For example:
$ cat ages.txt
Bob 12
Jane 48
Mark 3
Tashi 54
$ sort -k2 -n ages.txt
Mark 3
Bob 12
Jane 48
Tashi 54
If you append json data to query string, and parse it later in web api side. you can parse complex object. It's useful rather than post json object style. This is my solution.
//javascript file
var data = { UserID: "10", UserName: "Long", AppInstanceID: "100", ProcessGUID: "BF1CC2EB-D9BD-45FD-BF87-939DD8FF9071" };
var request = JSON.stringify(data);
request = encodeURIComponent(request);
doAjaxGet("/ProductWebApi/api/Workflow/StartProcess?data=", request, function (result) {
window.console.log(result);
});
//webapi file:
[HttpGet]
public ResponseResult StartProcess()
{
dynamic queryJson = ParseHttpGetJson(Request.RequestUri.Query);
int appInstanceID = int.Parse(queryJson.AppInstanceID.Value);
Guid processGUID = Guid.Parse(queryJson.ProcessGUID.Value);
int userID = int.Parse(queryJson.UserID.Value);
string userName = queryJson.UserName.Value;
}
//utility function:
public static dynamic ParseHttpGetJson(string query)
{
if (!string.IsNullOrEmpty(query))
{
try
{
var json = query.Substring(7, query.Length - 7); //seperate ?data= characters
json = System.Web.HttpUtility.UrlDecode(json);
dynamic queryJson = JsonConvert.DeserializeObject<dynamic>(json);
return queryJson;
}
catch (System.Exception e)
{
throw new ApplicationException("can't deserialize object as wrong string content!", e);
}
}
else
{
return null;
}
}
Also, this might help finding the actual location the btsnoop_hci.log is being saved:
adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"
We can export a jar file for Android library project without resource files by Android studio. It is also requirement what I met recently.
1. Config your build.gradle file
// Task to delete old jar
task clearJar(type: Delete){
delete 'release/lunademo.jar'
}
// task to export contents as jar
task makeJar(type: Copy) {
from ('build/intermediates/bundles/release/')
into ('build/libs/')
include ('classes.jar')
rename('classes.jar', 'lunademo.jar')
}
makeJar.dependsOn(clearJar, build)
2. Run gradlew makeJar under your project root
You will see your libs under dir as build/libs/ if you are luckily.
============================================================
If you met issue as "Socket timeout exception" on command line as below,
You can follow this steps to open Gradle window in the right part and click "makeJar" on Android studio like this,
Then go to build/libs dir, you will see your jar file.
Hope that it is helpful for u.
Good Luck @.@

This is the complex (curly) syntax for string interpolation. From the manual:
Complex (curly) syntax
This isn't called complex because the syntax is complex, but because it allows for the use of complex expressions.
Any scalar variable, array element or object property with a string representation can be included via this syntax. Simply write the expression the same way as it would appear outside the string, and then wrap it in
{
and}
. Since{
can not be escaped, this syntax will only be recognised when the$
immediately follows the{
. Use{\$
to get a literal{$
. Some examples to make it clear:<?php // Show all errors error_reporting(E_ALL); $great = 'fantastic'; // Won't work, outputs: This is { fantastic} echo "This is { $great}"; // Works, outputs: This is fantastic echo "This is {$great}"; echo "This is ${great}"; // Works echo "This square is {$square->width}00 centimeters broad."; // Works, quoted keys only work using the curly brace syntax echo "This works: {$arr['key']}"; // Works echo "This works: {$arr[4][3]}"; // This is wrong for the same reason as $foo[bar] is wrong outside a string. // In other words, it will still work, but only because PHP first looks for a // constant named foo; an error of level E_NOTICE (undefined constant) will be // thrown. echo "This is wrong: {$arr[foo][3]}"; // Works. When using multi-dimensional arrays, always use braces around arrays // when inside of strings echo "This works: {$arr['foo'][3]}"; // Works. echo "This works: " . $arr['foo'][3]; echo "This works too: {$obj->values[3]->name}"; echo "This is the value of the var named $name: {${$name}}"; echo "This is the value of the var named by the return value of getName(): {${getName()}}"; echo "This is the value of the var named by the return value of \$object->getName(): {${$object->getName()}}"; // Won't work, outputs: This is the return value of getName(): {getName()} echo "This is the return value of getName(): {getName()}"; ?>
Often, this syntax is unnecessary. For example, this:
$a = 'abcd';
$out = "$a $a"; // "abcd abcd";
behaves exactly the same as this:
$out = "{$a} {$a}"; // same
So the curly braces are unnecessary. But this:
$out = "$aefgh";
will, depending on your error level, either not work or produce an error because there's no variable named $aefgh
, so you need to do:
$out = "${a}efgh"; // or
$out = "{$a}efgh";
If you are using .NET 3.5 or newer you can use LINQ extension methods to achieve a "contains" check with the Any
extension method:
if(CartProducts.Any(prod => prod.ID == p.ID))
This will check for the existence of a product within CartProducts
which has an ID matching the ID of p
. You can put any boolean expression after the =>
to perform the check on.
This also has the benefit of working for LINQ-to-SQL queries as well as in-memory queries, where Contains
doesn't.
Mutable way:
import UserString
s = UserString.MutableString("EXAMPLE")
>>> type(s)
<type 'str'>
# Delete 'M'
del s[3]
# Turn it for immutable:
s = str(s)
You can set the default value of your Id in your db to newsequentialid() or newid(). Then the identity configuration of EF should work.
They do now, with latest version of MVC (and jquery validate packages). mvc51-release-notes#Unobtrusive
Thanks to this answer for pointing it out!
This is just because the application is built in non unicode language fonts and you are running the system on unicode fonts. change your default non unicode fonts to arabic by going in regional settings advanced tab in control panel. That will solve your problem.
The following worked for me:
ForceCursor = true;
Cursor = Cursors.Wait;
I got the same problem and it is not the solution that you told. So I changed the "from datetime import datetime" to "import datetime". After that with the help of "datetime.datetime" I can get the whole modules correctly. I guess this is the correct answer to that question.
The simple solution would be to use a ItemListener
. When the state changes, you would simply check the currently selected item and set the text accordingly
import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestComboBox06 {
public static void main(String[] args) {
new TestComboBox06();
}
public TestComboBox06() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException ex) {
} catch (InstantiationException ex) {
} catch (IllegalAccessException ex) {
} catch (UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JComboBox cb;
private JTextField field;
public TestPane() {
cb = new JComboBox(new String[]{"Item 1", "Item 2"});
field = new JTextField(12);
add(cb);
add(field);
cb.setSelectedItem(null);
cb.addItemListener(new ItemListener() {
@Override
public void itemStateChanged(ItemEvent e) {
Object item = cb.getSelectedItem();
if ("Item 1".equals(item)) {
field.setText("20");
} else if ("Item 2".equals(item)) {
field.setText("30");
}
}
});
}
}
}
A better solution would be to create a custom object that represents the value to be displayed and the value associated with it...
Updated
Now I no longer have a 10 month chewing on my ankles, I updated the example to use a ListCellRenderer
which is a more correct approach then been lazy and overriding toString
import java.awt.BorderLayout;

JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}
});
}
public class TestPane extends JPanel {
private JComboBox cb;
private JTextField field;
public TestPane() {
cb = new JComboBox(new Item[]{
new Item("Item 1", "20"),
new Item("Item 2", "30")});
cb.setRenderer(new ItemCelLRenderer());
field = new JTextField(12);
add(cb);
add(field);
cb.setSelectedItem(null);
cb.addItemListener(new ItemListener() {
@Override
public void itemStateChanged(ItemEvent e) {
Item item = (Item)cb.getSelectedItem();
field.setText(item.getValue());
}
});
}
}
public class Item {
private String value;
private String text;
public Item(String text, String value) {
this.text = text;
this.value = value;
}
public String getText() {
return text;
}
public String getValue() {
return value;
}
}
public class ItemCelLRenderer extends DefaultListCellRenderer {
@Override
public Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus); //To change body of generated methods, choose Tools | Templates.
if (value instanceof Item) {
setText(((Item)value).getText());
}
return this;
}
}
}
This will vary depending on your architecture and how it treats basic data types. It will also depend on whether the system requires natural alignment.
Look at the const
and static
section of the Rust book.
You can use something as follows:
const N: i32 = 5;
or
static N: i32 = 5;
in global space.
But these are not mutable. For mutability, you could use something like:
static mut N: i32 = 5;
Then reference them like:
unsafe {
N += 1;
println!("N: {}", N);
}
If your goal is only to take the files and not the folder, the approach I made was to use the file size
as a filter. This property is the current size of the file hosted by AWS. All the folders return 0 in that property.
The following is a C# code using linq but it shouldn't be hard to translate to Java.
var amazonClient = new AmazonS3Client(key, secretKey, region);
var listObjectsRequest= new ListObjectsRequest
{
BucketName = 'someBucketName',
Delimiter = 'someDelimiter',
Prefix = 'somePrefix'
};
var objects = amazonClient.ListObjects(listObjectsRequest);
var objectsInFolder = objects.S3Objects.Where(file => file.Size > 0).ToList();
same happen to me i just resolved by deleting "dist" file and re run the app.
The JPEXS Free Flash Decompiler has Java code to do this at in the source tree for both Chrome and Firefox (no support for Firefox's more recent cache2 though).
In case you don't want this changes to be committed at all do
git reset --hard
.
Next you can checkout to wanted branch, but remember that uncommitted changes will be lost.
Take a look at the following function - REPLACE():
select replace(DataColumn, StringToReplace, NewStringValue)
//example to replace the s in test with the number 1
select replace('test', 's', '1')
//yields te1t
http://msdn.microsoft.com/en-us/library/ms186862.aspx
EDIT
If you want to remove a string, simple use the replace function with an empty string as the third parameter like:
select replace(DataColumn, 'StringToRemove', '')
Also remember you can include custom indices to the array sent to the server like this
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<input type='checkbox' name='checkboxvar[4]' value='Option One'>4<br>
<input type='checkbox' name='checkboxvar[6]' value='Option Two'>6<br>
<input type='checkbox' name='checkboxvar[9]' value='Option Three'>9
</td>
</tr>
<input type='submit' class='buttons'>
</form>
This is particularly useful when you want to use the id
of individual objects in a server array accounts
(for instance) to send data back to the server and recognize same at server
<form method='post' id='userform' action='thisform.php'>
<tr>
<td>Trouble Type</td>
<td>
<?php foreach($accounts as $account) { ?>
<input type='checkbox' name='accounts[<?php echo $account->id ?>]' value='<?php echo $account->name ?>'>
<?php echo $account->name ?>
<br>
<?php } ?>
</td>
</tr>
<input type='submit' class='buttons'>
</form>
<?php
if (isset($_POST['accounts']))
{
print_r($_POST['accounts']);
}
?>
The example code leads to a memory leak in Tomcat (after undeploying the webapp, the classloader still remains in memory) which will cause an outofmemory
eventually. The way to solve it is to use the sqlite-jdbc-3.7.8.jar; it's a snapshot, so it doesn't appear for maven yet.
Easiest way to do is :
awk 'NR==FNR{a[$1]++;next} a[$1] ' file1 file2
Files are not necessary to be sorted.
You should only need to do a single join:
SELECT e.Grade, v.Score, e.CaseNum, e.FileNum, e.ActivityNum
FROM Evaluation e
INNER JOIN Value v ON e.CaseNum = v.CaseNum AND e.FileNum = v.FileNum AND e.ActivityNum = v.ActivityNum
If you want to trim the whitespace off just the beginning and end of the string, you can do something like this:
some_string = " Hello, world!\n "
new_string = some_string.strip()
# new_string is now "Hello, world!"
This works a lot like Qt's QString::trimmed() method, in that it removes leading and trailing whitespace, while leaving internal whitespace alone.
But if you'd like something like Qt's QString::simplified() method which not only removes leading and trailing whitespace, but also "squishes" all consecutive internal whitespace to one space character, you can use a combination of .split()
and " ".join
, like this:
some_string = "\t Hello, \n\t world!\n "
new_string = " ".join(some_string.split())
# new_string is now "Hello, world!"
In this last example, each sequence of internal whitespace replaced with a single space, while still trimming the whitespace off the start and end of the string.
Unexpected token errors in ESLint parsing occur due to incompatibility between your development environment and ESLint's current parsing capabilities with the ongoing changes with JavaScripts ES6~7.
Adding the "parserOptions" property to your .eslintrc is no longer enough for particular situations, such as using
static contextTypes = { ... } /* react */
in ES6 classes as ESLint is currently unable to parse it on its own. This particular situation will throw an error of:
error Parsing error: Unexpected token =
The solution is to have ESLint parsed by a compatible parser. babel-eslint is a package that saved me recently after reading this page and i decided to add this as an alternative solution for anyone coming later.
just add:
"parser": "babel-eslint"
to your .eslintrc
file and run npm install babel-eslint --save-dev
or yarn add -D babel-eslint
.
Please note that as the new Context API starting from React ^16.3
has some important changes, please refer to the official guide.
var str = " my awesome string "
str.trim();
for old browsers, use regex
str = str.replace(/^[ ]+|[ ]+$/g,'')
//str = "my awesome string"
According to nginx documentation
there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else
So you could define something like
location ~ (dir1|file2\.php) {
# empty
}
location / {
rewrite ^/(.*) http://example.com/$1 permanent;
}
Add extra columns as null for the table having less columns like
Select Col1, Col2, Col3, Col4, Col5 from Table1
Union
Select Col1, Col2, Col3, Null as Col4, Null as Col5 from Table2
I find that the best solution to comparing a datetime field to a date field is the following:
DECLARE @StartDate DATE = '5/1/2013',
@EndDate DATE = '5/1/2013'
SELECT *
FROM cases
WHERE Datediff(day, created_at, @StartDate) <= 0
AND Datediff(day, created_at, @EndDate) >= 0
This is equivalent to an inclusive between statement as it includes both the start and end date as well as those that fall between.
They are normal symbols as 'a' or '?' or any other. Just (invisible) entries in a string. \r moves cursor to the beginning of the line. \n goes one line down.
As for your replacement, you haven't specified what language you're using, so here's the sketch:
someString.replace("\r\n", "\n").replace("\r", "\n")
