Integer.parseInt(myString.replaceFirst("#", ""), 16)
"N/A" is not an integer. It must throw NumberFormatException if you try to parse it to an integer.
Check before parsing or handle Exception properly.

try{
int i = Integer.parseInt(input);

}
I changed Scanner fin = new Scanner(file); to Scanner fin = new Scanner(new File(file)); and it works perfectly now. I didn't think the difference mattered but there you go.
Exceptions in recent versions of Java aren't expensive enough to make their avoidance important. Use the try/catch block people have suggested; if you catch the exception early in the process (i.e., right after the user has entered it) then you're not going to have the problem later in the process (because it'll be the right type anyway).
Exceptions used to be a lot more expensive than they are now; don't optimize for performance until you know the exceptions are actually causing a problem (and they won't, here.)
The problem is that you use a localizing formatter that generates locale-specific decimal point, which is "," in your case. But Double.parseDouble() expects non-localized double literal. You could solve your problem by using a locale-specific parsing method or by changing locale of your formatter to something that uses "." as the decimal point. Or even better, avoid unnecessary formatting by using something like this:
double rounded = (double) Math.round(value * 100.0) / 100.0;
Old question I know, but this is now possible using the css property table-layout: fixed on the table tag. Answer below from this question CSS percentage width and text-overflow in a table cell
This is easily done by using table-layout: fixed, but a little tricky because not many people know about this CSS property.
table {
width: 100%;
table-layout: fixed;
}
See it in action at the updated fiddle here: http://jsfiddle.net/Fm5bM/4/
There's a more efficient way to do this in MongoDB 2.2+ now that you can use numeric array indexes in query object keys.
// Find all docs that have at least two name array elements.
db.accommodations.find({'name.1': {$exists: true}})
You can support this query with an index that uses a partial filter expression (requires 3.2+):
// index for at least two name array elements
db.accommodations.createIndex(
{'name.1': 1},
{partialFilterExpression: {'name.1': {$exists: true}}}
);
with many functions in matlab, you don't need to iterate at all.
for example, to multiply by it's position in the list:
m = [1:numel(list)]';
elm = list.*m;
vectorized algorithms in matlab are in general much faster.
If you are using React Router, I'd suggest looking into the react-router-bootstrap library which has a handy component LinkContainer. This component prevents default page reload so you don't have to deal with the event.
In your case it could look something like:
import { LinkContainer } from 'react-router-bootstrap';
<LinkContainer to={givePathHere}>
<span className="upvotes" onClick={this.upvote}>upvote</span>
</LinkContainer>
I also tried executing batch file that run daemon process/server at the end of CCNET task; The only way to make CruiseControl spawn an independent asynchronous process WITHOUT waiting for the end of process is:
use task scheduler to run the batch file as CCNET task (using schtasks.exe)
schtasks.exe /create /F /SC once /ST 08:50 /TN TaskName /TR "c:/path/to/batchFileName.bat"
you might need to kill the process at the start of ccnet
PS: the selected answer using "start cmd.exe" does not work; a new command prompt is indeed spawned, but CCNET will wait for the spawned cmd to finish.
You can use the instanceof operator for this. From MDN:
The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototype chain of an object.
If you don't know what prototypes and prototype chains are I highly recommend looking it up. Also here is a JS (TS works similar in this respect) example which might clarify the concept:
class Animal {_x000D_
name;_x000D_
_x000D_
constructor(name) {_x000D_
this.name = name;_x000D_
}_x000D_
}_x000D_
_x000D_
const animal = new Animal('fluffy');_x000D_
_x000D_
// true because Animal in on the prototype chain of animal_x000D_
console.log(animal instanceof Animal); // true_x000D_
// Proof that Animal is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(animal) === Animal.prototype); // true_x000D_
_x000D_
// true because Object in on the prototype chain of animal_x000D_
console.log(animal instanceof Object); _x000D_
// Proof that Object is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(Animal.prototype) === Object.prototype); // true_x000D_
_x000D_
console.log(animal instanceof Function); // false, Function not on prototype chain_x000D_
_x000D_
The prototype chain in this example is:
animal > Animal.prototype > Object.prototype
I don't see the benefit in aliasing out users tied to Schemas. Here is why....
Most people connect their user accounts to databases via roles initially, As soon as you assign a user to either the sysadmin, or the database role db_owner, in any form, that account is either aliased to the "dbo" user account, or has full permissions on a database. Once that occurs, no matter how you assign yourself to a scheme beyond your default schema (which has the same name as your user account), those dbo rights are assigned to those object you create under your user and schema. Its kinda pointless.....and just a namespace and confuses true ownership on those objects. Its poor design if you ask me....whomever designed it.
What they should have done is created "Groups", and thrown out schemas and role and just allow you to tier groups of groups in any combination you like, then at each tier tell the system if permissions are inherited, denied, or overwritten with custom ones. This would have been so much more intuitive and allowed DBA's to better control who the real owners are on those objects. Right now its implied in most cases the dbo default SQL Server user has those rights....not the user.
git config --global core.askpass
Run this first before cloning the same way, should be fixed!
I consider myself a bash junkie, BUT ... for the last 2 years have not find a single bash user friendly solution for this one. By "user-friendly" I mean just a single call away, which does not require me to remember complicated syntax + I can use the same find syntax as before , so the following solution works best for those ^^^
Copy paste this one in your shell and source the ~/.bash_aliases :
cat << "EOF" >> ~/.bash_aliases
# usage: source ~/.bash_aliases , instead of find type findd + rest of syntax
findd(){
dir=$1; shift ;
find $dir -not -path "*/node_modules/*" -not -path "*/build/*" \
-not -path "*/.cache/*" -not -path "*/.git/*" -not -path "*/venv/*" $@
}

Of course in order to add or remove dirs to exclude you would have to edit this alias func with your dirs of choice ...
def _col_seq_set(df, col_list, seq_list):
''' set dataframe 'df' col_list's sequence by seq_list '''
col_not_in_col_list = [x for x in list(df.columns) if x not in col_list]
for i in range(len(col_list)):
col_not_in_col_list.insert(seq_list[i], col_list[i])
return df[col_not_in_col_list]
DataFrame.col_seq_set = _col_seq_set
Converting is easy, setting date and time is a little tricky. Here's an example:
Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, 2000);
cal.set(Calendar.MONTH, 0);
cal.set(Calendar.DAY_OF_MONTH, 1);
cal.set(Calendar.HOUR_OF_DAY, 1);
cal.set(Calendar.MINUTE, 1);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
stmt.setDate(1, new java.sql.Date(cal.getTimeInMillis()));
Use the splice method.
ArrayName.splice(indexValueOfArray,1);
This removes 1 item from the array starting at indexValueOfArray.
Here is another example that return's a boolean value using try/catch.
private boolean doSomeThing(int index){
try {
if(index%2==0)
return true;
} catch (Exception e) {
System.out.println(e.getMessage());
}finally {
System.out.println("Finally!!! ;) ");
}
return false;
}
const regex = new RegExp(`ReGeX${testVar}ReGeX`);
...
string.replace(regex, "replacement");
Per some of the comments, it's important to note that you may want to escape the variable if there is potential for malicious content (e.g. the variable comes from user input)
In 2019, this would usually be written using a template string, and the above code has been updated. The original answer was:
var regex = new RegExp("ReGeX" + testVar + "ReGeX");
...
string.replace(regex, "replacement");
Solution:
use incognito new tab then test it again.
reason:
in my case another user logged in with my admin panel
html:
<input type="text" class="datepick" id="date_1" />
<input type="text" class="datepick" id="date_2" />
<input type="text" class="datepick" id="date_3" />
script:
$('.datepick').each(function(){
$(this).datepicker();
});
(pseudo coded up a bit to keep it simpler)
If you are using a pre-defined run configuration, go to classpath and try "Restore Default Entries". This will reconfigure the classpath for that configuration.
You can use the find command to search for a file:
find / -name virtualenvwrapper.sh
This will search all directories from the root for the file.
on ubuntu 12.04 LTS, installing through pip, it is installed to
/usr/local/bin/virtualenvwrapper.sh
on ubuntu 17.04, installing through pip as a normal user, it is installed to
~/.local/bin/virtualenvwrapper.sh
One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get
public class PageViewModel : IHandle<SomeMessage>
{
...
public async void Handle(SomeMessage message)
{
ShowLoadingAnimation();
// makes UI very laggy, but still not dead
await this.contentLoader.LoadContentAsync();
HideLoadingAnimation();
}
}
public class ContentLoader
{
public async Task LoadContentAsync()
{
var tasks = new List<Task>();
tasks.Add(DoCpuBoundWorkAsync());
tasks.Add(DoIoBoundWorkAsync());
tasks.Add(DoCpuBoundWorkAsync());
tasks.Add(DoSomeOtherWorkAsync());
await Task.WhenAll(tasks).ConfigureAwait(false);
}
}
Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.
To insert into a very long string it is nice to use names for the different arguments, instead of hoping they are in the right positions. This also makes it easier to replace multiple recurrences.
>>> 'Coordinates: {latitude}, {longitude}'.format(latitude='37.24N', longitude='-115.81W')
'Coordinates: 37.24N, -115.81W'
Taken from Format examples, where all the other Format-related answers are also shown.
In practical terms it means that the delegate is guaranteed to be invoked on the main thread. This is important because in the case of windows controls if you don't update their properties on the main thread then you either don't see the change, or the control raises an exception.
The pattern is:
void OnEvent(object sender, EventArgs e)
{
if (this.InvokeRequired)
{
this.Invoke(() => this.OnEvent(sender, e);
return;
}
// do stuff (now you know you are on the main thread)
}
You can use array_agg function for that:
SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";
Result:
| MOVIE | ACTOR |
|---|---|
| A | 1,2,3 |
| B | 4 |

Not sure if this sort of solves what you're after, or fits with your general development landscape but the first thing I would try would be to change the background colour of the button on the touchDown event.
Option 1:
You would need two events to be capture, UIControlEventTouchDown would be for when the user presses the button. UIControlEventTouchUpInside and UIControlEventTouchUpOutside will be for when they release the button to return it to the normal state
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setFrame:CGRectMake(10.0f, 10.0f, 100.0f, 20.f)];
[myButton setBackgroundColor:[UIColor blueColor]];
[myButton setTitle:@"click me:" forState:UIControlStateNormal];
[myButton setTitle:@"changed" forState:UIControlStateHighlighted];
[myButton addTarget:self action:@selector(buttonHighlight:) forControlEvents:UIControlEventTouchDown];
[myButton addTarget:self action:@selector(buttonNormal:) forControlEvents:UIControlEventTouchUpInside];
Option 2:
Return an image made from the highlight colour you want. This could also be a category.
+ (UIImage *)imageWithColor:(UIColor *)color {
CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
and then change the highlighted state of the button:
[myButton setBackgroundImage:[self imageWithColor:[UIColor greenColor]] forState:UIControlStateHighlighted];
Just as Brian said, you can use remote debugging:
mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 com.mycompany.app.App"
Then in your eclipse, you can use remote debugging and attach the debugger to localhost:1044.
Does it have to be specifically an InputStreamReader? How about using StringReader?
Otherwise, you could use StringBufferInputStream, but it's deprecated because of character conversion issues (which is why you should prefer StringReader).
Only one suggestion:-
Read SOA Concepts, Technology and Design by Thomas Erl.
It has very beautifully given the details about SOA in plain English and with case studies.
Using Spring's SimpleJdbcTemplate, I got it when I tried to do this:
String sqlString = "select pwy_code from approver where university_id = '123'";
List<Map<String, Object>> rows = getSimpleJdbcTemplate().queryForList(sqlString, uniId);
I had an argument to queryForList that didn't correspond to a question mark in the SQL. The first line should have been:
String sqlString = "select pwy_code from approver where university_id = ?";
Request.Form is a NameValueCollection. In NameValueCollection you can find the GetAllValues() method.
By the way the LINQ method also works.
This error is mainly caused by empty returned ajax calls, when trying to parse an empty JSON.
To solve this test if the returned data is empty
$.ajax({
url: url,
type: "get",
dataType: "json",
success: function (response) {
if(response.data.length == 0){
// EMPTY
}else{
var obj =jQuery.parseJSON(response.data);
console.log(obj);
}
}
});
A workspace is just a text file with a (.code-workspace) extension. You can look at it by opening it with a text editor. I too was frustrated by the idea of a workspace and how it is implemented in Visual Studio Code. I found a method that suits me.
Start with a single "project" folder.
Open Visual Studio Code and close any open workspaces or files or folders. You should see only "OPEN EDITORS" and "NO FOLDER OPENED" in the EXPLORER.
From the menu bar* → File → Open Folder.... Navigate to where you want to put your folder and right click to open a new folder. Name it whatever you want, then click on "Select Folder". It will appear in the *Visual Studio Code explorer.
Now from menu File → Save Workspace As.... Name the workspace and save it wherever you want to keep all your workspaces, (not necessarily where your project folders are). I put all mine in a folder called "Visual Studio Code workspace".
It will be saved as a (.code-workspace) file and is just an index to all the files and folders it contains (or points to) wherever they may be on your hard drive. You can look at it by opening it with a text editor. Close the folder you created and close Visual Studio Code.
Now find your workspace "file" and double click on it. This will open Visual Studio Code with the folder you created in your workspace. Or you can open Visual Studio Code and use "Open Workspace".
Any folders you create from within your Visual Studio Code workspace will be inside your first folder. If you want to add any more top level folders, create them first wherever you want them and then use "Add To Workspace.." from Visual Studio Code.
It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.
Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.
As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.
UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.
For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.
UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :
Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :
Find around the line 29 where it says :
isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
and replace it by (EDITED March 19, 2013: more accurate filter):
isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
UPDATE (March 19, 2013): Also replace $.browser.msie by navigator.userAgent.match(/msie [6]/i) around line 615 (and/or replace all $.browser.msie instances, if any), thanks joofow
... that's it!
Or download the already patched version from HERE (UPDATED March 19, 2013 ... thanks fairylee for pointing out the extra closing bracket)
NOTE: this is an unofficial patch and is unsupported by Fancybox's author, however it works as is. You may use it at your own risk ;)
Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.
You can do it with strtol, like this:
char *str = "ab234cid*(s349*(20kd", *p = str;
while (*p) { // While there are more characters to process...
if ( isdigit(*p) || ( (*p=='-'||*p=='+') && isdigit(*(p+1)) )) {
// Found a number
long val = strtol(p, &p, 10); // Read number
printf("%ld\n", val); // and print it.
} else {
// Otherwise, move on to the next character.
p++;
}
}

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
Where str is your XML string. See the MSDN article for more info.
You can simply use this:
'07311954' in df.date.values which returns True or False
Here is the further explanation:
In pandas, using in check directly with DataFrame and Series (e.g. val in df or val in series ) will check whether the val is contained in the Index.
BUT you can still use in check for their values too (instead of Index)! Just using val in df.col_name.values
or val in series.values. In this way, you are actually checking the val with a Numpy array.
And .isin(vals) is the other way around, it checks whether the DataFrame/Series values are in the vals. Here vals must be set or list-like. So this is not the natural way to go for the question.
It seems this is now something developers are allowed to do: the iOS Developer Agreement was changed yesterday and appears to have been ammended in a such a way as to make embedding a Python interpretter in your application legal:
SECTION 3.3.2 — INTERPRETERS
Old:
3.3.2 An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise. Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application.
New:
3.3.2 An Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts, code and interpreters are packaged in the Application and not downloaded. The only exception to the foregoing is scripts and code downloaded and run by Apple’s built-in WebKit framework.
Use read -p:
# fullname="USER INPUT"
read -p "Enter fullname: " fullname
# user="USER INPUT"
read -p "Enter user: " user
If you like to confirm:
read -p "Continue? (Y/N): " confirm && [[ $confirm == [yY] || $confirm == [yY][eE][sS] ]] || exit 1
You should also quote your variables to prevent pathname expansion and word splitting with spaces:
# passwd "$user"
# mkdir "$home"
# chown "$user:$group" "$home"
What about an onclick function:
<form id="form">
<input type="text" name="firstInput">
<button type="button" name="namebutton"
onClick="$('#gif').css('visibility', 'visible');
$('#form').submit();">
</form>
Of course you can put this in a function and then trigger it with an onClick
I have also used a non-generic version, using the new keyword:
public interface IMetadata
{
Type DataType { get; }
object Data { get; }
}
public interface IMetadata<TData> : IMetadata
{
new TData Data { get; }
}
Explicit interface implementation is used to allow both Data members:
public class Metadata<TData> : IMetadata<TData>
{
public Metadata(TData data)
{
Data = data;
}
public Type DataType
{
get { return typeof(TData); }
}
object IMetadata.Data
{
get { return Data; }
}
public TData Data { get; private set; }
}
You could derive a version targeting value types:
public interface IValueTypeMetadata : IMetadata
{
}
public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{
}
public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
public ValueTypeMetadata(TData data) : base(data)
{}
}
This can be extended to any kind of generic constraints.
Once you have the source trees, e.g.
diff -ENwbur repos1/ repos2/
Even better
diff -ENwbur repos1/ repos2/ | kompare -o -
and have a crack at it in a good gui tool :)
Use the vectorised str method replace:
In [30]:
df['range'] = df['range'].str.replace(',','-')
df
Out[30]:
range
0 (2-30)
1 (50-290)
EDIT
So if we look at what you tried and why it didn't work:
df['range'].replace(',','-',inplace=True)
from the docs we see this desc:
str or regex: str: string exactly matching to_replace will be replaced with value
So because the str values do not match, no replacement occurs, compare with the following:
In [43]:
df = pd.DataFrame({'range':['(2,30)',',']})
df['range'].replace(',','-', inplace=True)
df['range']
Out[43]:
0 (2,30)
1 -
Name: range, dtype: object
here we get an exact match on the second row and the replacement occurs.
I have found this to be the easiest way by far.
Use this method:
public static String getJSON(String url) {
HttpsURLConnection con = null;
try {
URL u = new URL(url);
con = (HttpsURLConnection) u.openConnection();
con.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
return sb.toString();
} catch (MalformedURLException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} finally {
if (con != null) {
try {
con.disconnect();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
return null;
}
And use it like this:
String json = getJSON(url);
JSONObject obj;
try {
obj = new JSONObject(json);
JSONArray results_arr = obj.getJSONArray("results");
final int n = results_arr.length();
for (int i = 0; i < n; ++i) {
// get the place id of each object in JSON (Google Search API)
String place_id = results_arr.getJSONObject(i).getString("place_id");
}
}

C++ and Java are different languages.
The Java C-style cast operator is much more restricted than the C/C++ version. Effectively the Java cast is like the C++ dynamic_cast if the object you have cannot be cast to the new class you will get a run time (or if there is enough information in the code a compile time) exception. Thus the C++ idea of not using C type casts is not a good idea in Java
Based on the same basic idea as in @Will Hartung's answer, here is my magic one-tag extensible template engine. It even includes documentation and an example :-)
WEB-INF/tags/block.tag:
<%--
The block tag implements a basic but useful extensible template system.
A base template consists of a block tag without a 'template' attribute.
The template body is specified in a standard jsp:body tag, which can
contain EL, JSTL tags, nested block tags and other custom tags, but
cannot contain scriptlets (scriptlets are allowed in the template file,
but only outside of the body and attribute tags). Templates can be
full-page templates, or smaller blocks of markup included within a page.
The template is customizable by referencing named attributes within
the body (via EL). Attribute values can then be set either as attributes
of the block tag element itself (convenient for short values), or by
using nested jsp:attribute elements (better for entire blocks of markup).
Rendering a template block or extending it in a child template is then
just a matter of invoking the block tag with the 'template' attribute set
to the desired template name, and overriding template-specific attributes
as necessary to customize it.
Attribute values set when rendering a tag override those set in the template
definition, which override those set in its parent template definition, etc.
The attributes that are set in the base template are thus effectively used
as defaults. Attributes that are not set anywhere are treated as empty.
Internally, attributes are passed from child to parent via request-scope
attributes, which are removed when rendering is complete.
Here's a contrived example:

Some simpler example code for using globalAlpha:
ctx.save();
ctx.globalAlpha = 0.4;
ctx.drawImage(img, x, y);
ctx.restore();
If you need img to be loaded:
var img = new Image();
img.onload = function() {
ctx.save();
ctx.globalAlpha = 0.4;
ctx.drawImage(img, x, y);
ctx.restore()
};
img.src = "http://...";
Notes:
Set the 'src' last, to guarantee that your onload handler is called on all platforms, even if the image is already in the cache.
Wrap changes to stuff like globalAlpha between a save and restore (in fact use them lots), to make sure you don't clobber settings from elsewhere, particularly when bits of drawing code are going to be called from events.
You could use NOT IN:
SELECT A.* FROM A WHERE ID NOT IN(SELECT ID FROM B)
However, meanwhile i prefer NOT EXISTS:
SELECT A.* FROM A WHERE NOT EXISTS(SELECT 1 FROM B WHERE B.ID=A.ID)
There are other options as well, this article explains all advantages and disadvantages very well:
Should I use NOT IN, OUTER APPLY, LEFT OUTER JOIN, EXCEPT, or NOT EXISTS?
Assign the second variable for the $.each function() as well, makes it lot easier as it'll provide you the data (so you won't have to work with the indicies).
$.each(json, function(arrayID,group) {
console.log('<a href="'+group.GROUP_ID+'">');
$.each(group.EVENTS, function(eventID,eventData) {
console.log('<p>'+eventData.SHORT_DESC+'</p>');
});
});
Should print out everything you were trying in your question.

edit renamed the variables to make it bit easier to understand what is what.

You can do this be using a new Subject too:
Typescript:
let subject = new Subject();
get_categories(...) {
this.http.post(...).subscribe(
(response) => {
this.total = response.json();
subject.next();
}
);
return subject; // can be subscribed as well
}
get_categories(...).subscribe(
(response) => {
// ...
}
);
To add to the already good advice, as I had an issue installing IPython when I didn't have write permissions to /usr/local.
pip uses distutils to do its install and this thread discusses how that can cause a problem as it relies on the sys.prefix setting.
My issue happened when the IPython install tried to write to '/usr/local/share/man/man1' with Permission denied. As the install failed it didn't seem to write the IPython files in the bin directory.
Using "--user" worked and the files were written to ~/.local. Adding ~/.local/bin to the $PATH meant I could use "ipython" from there.
However I'm trying to install this for a number of users and had been given write permission to the /usr/local/lib/python2.7 directory. I created a "bin" directory under there and set directives for distutils:
vim ~/.pydistutils.cfg
[install]
install-data=/usr/local/lib/python2.7
install-scripts=/usr/local/lib/python2.7/bin
then (-I is used to force the install despite previous failures/.local install):
pip install -I ipython
Then I added /usr/local/lib/python2.7/bin to $PATH.
I thought I'd include this in case anyone else has similar issues on a machine they don't have sudo access to.
In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325
Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.
Make sure that you have checked it to work properly with the IE version you specify.
You can loop through all directories including hidden directrories (beginning with a dot) with:
for file in */ .*/ ; do echo "$file is a directory"; done
note: using the list */ .*/ works in zsh only if there exist at least one hidden directory in the folder. In bash it will show also . and ..
Another possibility for bash to include hidden directories would be to use:
shopt -s dotglob;
for file in */ ; do echo "$file is a directory"; done
If you want to exclude symlinks:
for file in */ ; do
if [[ -d "$file" && ! -L "$file" ]]; then
echo "$file is a directory";
fi;
done
To output only the trailing directory name (A,B,C as questioned) in each solution use this within the loops:
file="${file%/}" # strip trailing slash
file="${file##*/}" # strip path and leading slash
echo "$file is the directoryname without slashes"
mkdir /tmp/A /tmp/B /tmp/C "/tmp/ dir with spaces"
for file in /tmp/*/ ; do file="${file%/}"; echo "${file##*/}"; done
Using Async await -
here one async function func1 is returning a resolved value, and func2 is throwing a error and returning a null in this situation, we can handle it how we want and return accordingly.
const callingFunction = async () => {
const manyPromises = await Promise.all([func1(), func2()]);
console.log(manyPromises);
}
const func1 = async () => {
return 'func1'
}
const func2 = async () => {
try {
let x;
if (!x) throw "x value not present"
} catch(err) {
return null
}
}
callingFunction();
Output is - [ 'func1', null ]
You are reading all rows into a list, then processing that list. Don't do that.
Process your rows as you produce them. If you need to filter the data first, use a generator function:
import csv
def getstuff(filename, criterion):
with open(filename, "rb") as csvfile:
datareader = csv.reader(csvfile)
yield next(datareader) # yield the header row
count = 0
for row in datareader:
if row[3] == criterion:
yield row
count += 1
elif count:
# done when having read a consecutive series of rows
return
I also simplified your filter test; the logic is the same but more concise.
Because you are only matching a single sequence of rows matching the criterion, you could also use:
import csv
from itertools import dropwhile, takewhile
def getstuff(filename, criterion):
with open(filename, "rb") as csvfile:
datareader = csv.reader(csvfile)
yield next(datareader) # yield the header row
# first row, plus any subsequent rows that match, then stop
# reading altogether
# Python 2: use `for row in takewhile(...): yield row` instead
# instead of `yield from takewhile(...)`.
yield from takewhile(
lambda r: r[3] == criterion,
dropwhile(lambda r: r[3] != criterion, datareader))
return
You can now loop over getstuff() directly. Do the same in getdata():
def getdata(filename, criteria):
for criterion in criteria:
for row in getstuff(filename, criterion):
yield row
Now loop directly over getdata() in your code:
for row in getdata(somefilename, sequence_of_criteria):
# process row
You now only hold one row in memory, instead of your thousands of lines per criterion.
yield makes a function a generator function, which means it won't do any work until you start looping over it.
SP is the stack register a shortcut for typing r13. LR is the link register a shortcut for r14. And PC is the program counter a shortcut for typing r15.
When you perform a call, called a branch link instruction, bl, the return address is placed in r14, the link register. the program counter pc is changed to the address you are branching to.
There are a few stack pointers in the traditional ARM cores (the cortex-m series being an exception) when you hit an interrupt for example you are using a different stack than when running in the foreground, you dont have to change your code just use sp or r13 as normal the hardware has done the switch for you and uses the correct one when it decodes the instructions.
The traditional ARM instruction set (not thumb) gives you the freedom to use the stack in a grows up from lower addresses to higher addresses or grows down from high address to low addresses. the compilers and most folks set the stack pointer high and have it grow down from high addresses to lower addresses. For example maybe you have ram from 0x20000000 to 0x20008000 you set your linker script to build your program to run/use 0x20000000 and set your stack pointer to 0x20008000 in your startup code, at least the system/user stack pointer, you have to divide up the memory for other stacks if you need/use them.
Stack is just memory. Processors normally have special memory read/write instructions that are PC based and some that are stack based. The stack ones at a minimum are usually named push and pop but dont have to be (as with the traditional arm instructions).
If you go to http://github.com/lsasim I created a teaching processor and have an assembly language tutorial. Somewhere in there I go through a discussion about stacks. It is NOT an arm processor but the story is the same it should translate directly to what you are trying to understand on the arm or most other processors.
Say for example you have 20 variables you need in your program but only 16 registers minus at least three of them (sp, lr, pc) that are special purpose. You are going to have to keep some of your variables in ram. Lets say that r5 holds a variable that you use often enough that you dont want to keep it in ram, but there is one section of code where you really need another register to do something and r5 is not being used, you can save r5 on the stack with minimal effort while you reuse r5 for something else, then later, easily, restore it.
Traditional (well not all the way back to the beginning) arm syntax:
...
stmdb r13!,{r5}
...temporarily use r5 for something else...
ldmia r13!,{r5}
...
stm is store multiple you can save more than one register at a time, up to all of them in one instruction.
db means decrement before, this is a downward moving stack from high addresses to lower addresses.
You can use r13 or sp here to indicate the stack pointer. This particular instruction is not limited to stack operations, can be used for other things.
The ! means update the r13 register with the new address after it completes, here again stm can be used for non-stack operations so you might not want to change the base address register, leave the ! off in that case.
Then in the brackets { } list the registers you want to save, comma separated.
ldmia is the reverse, ldm means load multiple. ia means increment after and the rest is the same as stm
So if your stack pointer were at 0x20008000 when you hit the stmdb instruction seeing as there is one 32 bit register in the list it will decrement before it uses it the value in r13 so 0x20007FFC then it writes r5 to 0x20007FFC in memory and saves the value 0x20007FFC in r13. Later, assuming you have no bugs when you get to the ldmia instruction r13 has 0x20007FFC in it there is a single register in the list r5. So it reads memory at 0x20007FFC puts that value in r5, ia means increment after so 0x20007FFC increments one register size to 0x20008000 and the ! means write that number to r13 to complete the instruction.
Why would you use the stack instead of just a fixed memory location? Well the beauty of the above is that r13 can be anywhere it could be 0x20007654 when you run that code or 0x20002000 or whatever and the code still functions, even better if you use that code in a loop or with recursion it works and for each level of recursion you go you save a new copy of r5, you might have 30 saved copies depending on where you are in that loop. and as it unrolls it puts all the copies back as desired. with a single fixed memory location that doesnt work. This translates directly to C code as an example:
void myfun ( void )
{
int somedata;
}
In a C program like that the variable somedata lives on the stack, if you called myfun recursively you would have multiple copies of the value for somedata depending on how deep in the recursion. Also since that variable is only used within the function and is not needed elsewhere then you perhaps dont want to burn an amount of system memory for that variable for the life of the program you only want those bytes when in that function and free that memory when not in that function. that is what a stack is used for.
A global variable would not be found on the stack.
Going back...
Say you wanted to implement and call that function you would have some code/function you are in when you call the myfun function. The myfun function wants to use r5 and r6 when it is operating on something but it doesnt want to trash whatever someone called it was using r5 and r6 for so for the duration of myfun() you would want to save those registers on the stack. Likewise if you look into the branch link instruction (bl) and the link register lr (r14) there is only one link register, if you call a function from a function you will need to save the link register on each call otherwise you cant return.
...
bl myfun
<--- the return from my fun returns here
...
myfun:
stmdb sp!,{r5,r6,lr}
sub sp,#4 <--- make room for the somedata variable
...
some code here that uses r5 and r6
bl more_fun <-- this modifies lr, if we didnt save lr we wouldnt be able to return from myfun
<---- more_fun() returns here
...
add sp,#4 <-- take back the stack memory we allocated for the somedata variable
ldmia sp!,{r5,r6,lr}
mov pc,lr <---- return to whomever called myfun.
So hopefully you can see both the stack usage and link register. Other processors do the same kinds of things in a different way. for example some will put the return value on the stack and when you execute the return function it knows where to return to by pulling a value off of the stack. Compilers C/C++, etc will normally have a "calling convention" or application interface (ABI and EABI are names for the ones ARM has defined). if every function follows the calling convention, puts parameters it is passing to functions being called in the right registers or on the stack per the convention. And each function follows the rules as to what registers it does not have to preserve the contents of and what registers it has to preserve the contents of then you can have functions call functions call functions and do recursion and all kinds of things, so long as the stack does not go so deep that it runs into the memory used for globals and the heap and such, you can call functions and return from them all day long. The above implementation of myfun is very similar to what you would see a compiler produce.
ARM has many cores now and a few instruction sets the cortex-m series works a little differently as far as not having a bunch of modes and different stack pointers. And when executing thumb instructions in thumb mode you use the push and pop instructions which do not give you the freedom to use any register like stm it only uses r13 (sp) and you cannot save all the registers only a specific subset of them. the popular arm assemblers allow you to use
push {r5,r6}
...
pop {r5,r6}
in arm code as well as thumb code. For the arm code it encodes the proper stmdb and ldmia. (in thumb mode you also dont have the choice as to when and where you use db, decrement before, and ia, increment after).
No you absolutly do not have to use the same registers and you dont have to pair up the same number of registers.
push {r5,r6,r7}
...
pop {r2,r3}
...
pop {r1}
assuming there is no other stack pointer modifications in between those instructions if you remember the sp is going to be decremented 12 bytes for the push lets say from 0x1000 to 0x0FF4, r5 will be written to 0xFF4, r6 to 0xFF8 and r7 to 0xFFC the stack pointer will change to 0x0FF4. the first pop will take the value at 0x0FF4 and put that in r2 then the value at 0x0FF8 and put that in r3 the stack pointer gets the value 0x0FFC. later the last pop, the sp is 0x0FFC that is read and the value placed in r1, the stack pointer then gets the value 0x1000, where it started.
The ARM ARM, ARM Architectural Reference Manual (infocenter.arm.com, reference manuals, find the one for ARMv5 and download it, this is the traditional ARM ARM with ARM and thumb instructions) contains pseudo code for the ldm and stm ARM istructions for the complete picture as to how these are used. Likewise well the whole book is about the arm and how to program it. Up front the programmers model chapter walks you through all of the registers in all of the modes, etc.
If you are programming an ARM processor you should start by determining (the chip vendor should tell you, ARM does not make chips it makes cores that chip vendors put in their chips) exactly which core you have. Then go to the arm website and find the ARM ARM for that family and find the TRM (technical reference manual) for the specific core including revision if the vendor has supplied that (r2p0 means revision 2.0 (two point zero, 2p0)), even if there is a newer rev, use the manual that goes with the one the vendor used in their design. Not every core supports every instruction or mode the TRM tells you the modes and instructions supported the ARM ARM throws a blanket over the features for the whole family of processors that that core lives in. Note that the ARM7TDMI is an ARMv4 NOT an ARMv7 likewise the ARM9 is not an ARMv9. ARMvNUMBER is the family name ARM7, ARM11 without a v is the core name. The newer cores have names like Cortex and mpcore instead of the ARMNUMBER thing, which reduces confusion. Of course they had to add the confusion back by making an ARMv7-m (cortex-MNUMBER) and the ARMv7-a (Cortex-ANUMBER) which are very different families, one is for heavy loads, desktops, laptops, etc the other is for microcontrollers, clocks and blinking lights on a coffee maker and things like that. google beagleboard (Cortex-A) and the stm32 value line discovery board (Cortex-M) to get a feel for the differences. Or even the open-rd.org board which uses multiple cores at more than a gigahertz or the newer tegra 2 from nvidia, same deal super scaler, muti core, multi gigahertz. A cortex-m barely brakes the 100MHz barrier and has memory measured in kbytes although it probably runs of a battery for months if you wanted it to where a cortex-a not so much.
sorry for the very long post, hope it is useful.
If INSERTS are rare, I would avoid doing a NOT EXISTS (...) since it emits a SELECT on all updates. Instead, take a look at wildpeaks answer: https://dba.stackexchange.com/questions/5815/how-can-i-insert-if-key-not-exist-with-postgresql
CREATE OR REPLACE FUNCTION upsert_tableName(arg1 type, arg2 type) RETURNS VOID AS $$
DECLARE
BEGIN
UPDATE tableName SET col1 = value WHERE colX = arg1 and colY = arg2;
IF NOT FOUND THEN
INSERT INTO tableName values (value, arg1, arg2);
END IF;
END;
$$ LANGUAGE 'plpgsql';
This way Postgres will initially try to do a UPDATE. If no rows was affected, it will fall back to emitting an INSERT.
My suggestion:
$http({
method: 'DELETE',
url: '/roles/' + roleid,
data: {
user: userId
},
headers: {
'Content-type': 'application/json;charset=utf-8'
}
})
.then(function(response) {
console.log(response.data);
}, function(rejection) {
console.log(rejection.data);
});
Why not set ON CASCADE DELETE on Foreign Key patron_info.pid?

Your question is a bit unclear, but I think you want (requires using System.Linq;):
var result = yourArrayOfStrings.SelectMany(s => s).ToArray();
Another solution is:
var result = string.Concat(yourArrayOfStrings).ToCharArray();
The best solution is my method:
In my method, only full words are detected,But in other ways it is not.
for example:
$text='hello world!';
if(strpos($text, 'wor') === FALSE) {
echo '"wor" not found in string';
}
Result: strpos returned true!!! but in my method return false.
My method:
public function searchInLine($txt,$word){
$txt=strtolower($txt);
$word=strtolower($word);
$word_length=strlen($word);
$string_length=strlen($txt);
if(strpos($txt,$word)!==false){
$indx=strpos($txt,$word);
$last_word=$indx+$word_length;
if($indx==0){
if(strpos($txt,$word." ")!==false){
return true;
}
if(strpos($txt,$word.".")!==false){
return true;
}
if(strpos($txt,$word.",")!==false){
return true;
}
if(strpos($txt,$word."?")!==false){
return true;
}
if(strpos($txt,$word."!")!==false){
return true;
}
}else if($last_word==$string_length){
if(strpos($txt," ".$word)!==false){
return true;
}
if(strpos($txt,".".$word)!==false){
return true;
}
if(strpos($txt,",".$word)!==false){
return true;
}
if(strpos($txt,"?".$word)!==false){
return true;
}
if(strpos($txt,"!".$word)!==false){
return true;
}
}else{
if(strpos($txt," ".$word." ")!==false){
return true;
}
if(strpos($txt," ".$word.".")!==false){
return true;
}
if(strpos($txt," ".$word.",")!==false){

You cannot alter a column to be an IDENTITY column. What you'll need to do is create a new column which is defined as an IDENTITY from the get-go, then drop the old column, and rename the new one to the old name.
ALTER TABLE (yourTable) ADD NewColumn INT IDENTITY(1,1)
ALTER TABLE (yourTable) DROP COLUMN OldColumnName
EXEC sp_rename 'yourTable.NewColumn', 'OldColumnName', 'COLUMN'

If all you're trying to do is to get attribute1 in your global namespace, version 3 seems just fine. Why is it overkill prefix ?
In version 2, instead of
from module import attribute1
you can do
attribute1 = module.attribute1
Use a nice editor like SciTe, select your code, press Ctrl + Q and done.
If you don't have an editor that supports block comments you can use a triple quoted string at the start and the end of your code block to 'effectively' comment it out. It is not the best practice though.
This is more concise:
<?php echo get_post_field('post_content', $post->ID); ?>
and this even more:
<?= get_post_field('post_content', $post->ID) ?>

int width = this.Parent == null ? this.Width : this.Parent.Width; this allows you to use auto-grow label when docked to a parent, e.g. a panel.
this.Height = sz.Height + Padding.Bottom + Padding.Top; here we take care of padding for top and bottom.

In short:
When there is a requirement to connect / integrate systems, you will probably need to connect to some data source and then process this data to match your business requirements.
In order to do that:
1) You could develop custom program that would do it (might be time consuming and hard to understand, maintain for other developer)
2) Alternatively, you could use Apache Camel to do it in standardised way (it has most of the connectors already developed for you, you just need to set it up and plug your logic - called Process):
Camel will help you to:
By using Apache Camel you will make it easy to understand / maintain / extend your system to another developer.
Apache Camel is developed with Enterprise Integration Patterns. The patterns help you to integrate systems in a good way :-)

Note that as a string, it should be represented in C# as "\\d+", or @"\d+"
You might output your DataFrame as a csv file and then use mysqlimport to import your csv into your mysql.
Seems pandas's build-in sql util provide a write_frame function but only works in sqlite.
I found something useful, you might try this
You can easily solve that in 2 steps:
1- Reach the child element using querySelector like that:
var target = element[0].querySelector('tbody tr:first-child td')
2- Transform it to an angular.element object again by doing:
var targetElement = angular.element(target)
You will then have access to all expected methods on the targetElement variable.
Deleting package-lock.json and node_modules then npm install worked for me.
Yes, case insensitivity can be enabled and disabled at will in Java regex.
It looks like you want something like this:
System.out.println(
"Have a meRry MErrY Christmas ho Ho hO"
.replaceAll("(?i)\\b(\\w+)(\\s+\\1)+\\b", "$1")
);
// Have a meRry Christmas ho
Note that the embedded Pattern.CASE_INSENSITIVE flag is (?i) not \?i. Note also that one superfluous \b has been removed from the pattern.
The (?i) is placed at the beginning of the pattern to enable case-insensitivity. In this particular case, it is not overridden later in the pattern, so in effect the whole pattern is case-insensitive.
It is worth noting that in fact you can limit case-insensitivity to only parts of the whole pattern. Thus, the question of where to put it really depends on the specification (although for this particular problem it doesn't matter since \w is case-insensitive.
To demonstrate, here's a similar example of collapsing runs of letters like "AaAaaA" to just "A".
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("(?i)\\b([A-Z])\\1+\\b", "$1")
); // A e I O u
Now suppose that we specify that the run should only be collapsed only if it starts with an uppercase letter. Then we must put the (?i) in the appropriate place:
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("\\b([A-Z])(?i)\\1+\\b", "$1")
); // A eeEeeE I O uuUuUuu
More generally, you can enable and disable any flag within the pattern as you wish.
java.util.regex.Pattern/regex/i (Pattern.CASE_INSENSITIVE in Java), you can do /(?i)regex//first(?i)second(?-i)third//first(?i:second)third/\b between a \w and a \s)A trivial approach would be to replace
<[^>]*>
with nothing. But depending on how ill-structured your input is that may well fail.
take a list of string as like
List<string> colValListForValidation = new List<string>();
and match string before the task. it will help you bcz all merge cells will have same value
You can use a grid layout to vertically center the image.
.frame {
display: grid;
grid-template-areas: "."
"img"
"."
grid-template-rows: 1fr auto 1fr;
grid-template-columns: auto;
}
.frame img {
grid-area: img;
}
This will create a 3 row 1 column grid layout with unnamed 1 fraction wide spacers at the top and bottom, and an area named img of auto height (size of the content).
The img will use the space it prefers, and the spacers at top and bottom will use the remaining height split to two equal fractions, resulting in the img element to be vertically centered.
Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885
This doesn't rely on serialization nor on content negotiation.
[HttpGet]
public ContentResult Index() {
return new ContentResult {
ContentType = "text/html",
StatusCode = (int)HttpStatusCode.OK,
Content = "<html><body>Hello World</body></html>"
};
}

If you want to apply styles only to an element which is its parents' first child, is it better to use :first-child pseudo-class
.social:first-child{
border-bottom: dotted 1px #6d6d6d;
padding-top: 0;
}
.social{
border: 0;
width: 330px;
height: 75px;
float: right;
text-align: left;
padding: 10px 0;
}
Then, the rule .social has both common styles and the last element's styles.
And .social:first-child overrides them with first element's styles.
You could also use :last-child selector, but :first-childis more supported by old browsers: see
https://developer.mozilla.org/en-US/docs/CSS/:first-child#Browser_compatibility and https://developer.mozilla.org/es/docs/CSS/:last-child#Browser_compatibility.
you can use line.seperator for appending new line in
for /f "delims=" %%i in (count.txt) do set c=%%i

You can force cut to display all fields and subsequent ones adding - to field number.
NAME=`basename "$FILE"`
EXTENSION=`echo "$NAME" | cut -d'.' -f2-`
So if FILE is eth0.pcap.gz, the EXTENSION will be pcap.gz
Using the same logic, you can also fetch the file name using '-' with cut as follows :
NAME=`basename "$FILE" | cut -d'.' -f-1`
This works even for filenames that do not have any extension.
You can try this:
SELECT * FROM MYTABLE WHERE DATE BETWEEN '03/10/2014 06:25:00' and '03/12/2010 6:25:00'
If you want to use class, you can do this.

function x(){}
function y(){}
export default class Helper{
static x(){ x(); }
static y(){ y(); }
}
App.js
import Helper from 'helper.js';
/****/

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.
This is some pseudocodish JavaScript:
Client:
var websocket = new WebSocket("server address");
websocket.onmessage = function(str) {
console.log("Someone sent: ", str);
};
// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
id: "client1"
}));
// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
to: "client2",
data: "foo"
}));
Server:
var clients = {};
server.on("data", function(client, str) {
var obj = JSON.parse(str);
if("id" in obj) {
// New client, add it to the id/client object
clients[obj.id] = client;
} else {
// Send data to the client requested
clients[obj.to].send(obj.data);
}
});
Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).
I would rather set max listeners number in your own code:
var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

This is the most important part in the code provided in the original post.
Button one = (Button) this.findViewById(R.id.button1);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
one.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
mp.start();
}
});
To explain it step by step:
Button one = (Button) this.findViewById(R.id.button1);
First is the initialization of the button to be used in playing the sound. We use the Activity's findViewById, passing the Id we assigned to it (in this example's case: R.id.button1), to get the button that we need. We cast it as a Button so that it is easy to assign it to the variable one that we are initializing. Explaining more of how this works is out of scope for this answer. This gives a brief insight on how it works.
final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
This is how to initialize a MediaPlayer. The MediaPlayer follows the Static Factory Method Design Pattern. To get an instance, we call its create() method and pass it the context and the resource Id of the sound we want to play, in this case R.raw.soho. We declare it as final. Jon Skeet provided a great explanation on why we do so here.
one.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
//code
}
});
Finally, we set what our previously initialized button will do. Play a sound on button click! To do this, we set the OnClickListener of our button one. Inside is only one method, onClick() which contains what instructions the button should do on click.
public void onClick(View v) {
mp.start();
}
To play the sound, we call MediaPlayer's start() method. This method starts the playback of the sound.
There, you can now play a sound on button click in Android!
Bonus part:
As noted in the comment belowThanks Langusten Gustel!, and as recommended in the Android Developer Reference, it is important to call the release() method to free up resources that will no longer be used. Usually, this is done once the sound to be played has completed playing. To do so, we add an OnCompletionListener to our mp like so:
mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
//code
}
});
Inside the onCompletion method, we release it like so:
public void onCompletion(MediaPlayer mp) {
mp.release();
}
There are obviously better ways of implementing this. For example, you can make the MediaPlayer a class variable and handle its lifecycle along with the lifecycle of the Fragment or Activity that uses it. However, this is a topic for another question. To keep the scope of this answer small, I wrote it just to illustrate how to play a sound on button click in Android.
First. You should put your statements inside a block, and in this case the onCreate method.
Second. You initialized the button as variable one, then you used a variable zero and set its onClickListener to an incomplete onClickListener. Use the variable one for the setOnClickListener.
Third, put the logic to play the sound inside the onClick.
In summary:
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class BasicScreenActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_basic_screen);
Button one = (Button)this.findViewById(R.id.button1);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
one.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
mp.start();
}
});
}
}
Is there an easy way to view all methods which contain this comment? Some sort of menu option?
Yes, choose one of the following:
Go to Window ? Show View ? Tasks (Not TaskList). The new view will show up where the "Console" and "Problems" tabs are by default.
As mentioned elsewhere, you can see them next to the scroll bar as little blue rectangles if you have the source file in question open.
If you just want the // TODO Auto-generated method stub messages (rather than all // TODO messages) you should use the search function (Ctrl-F for ones in this file Search ? Java Search ? Search string for the ability to specify this workspace, that file, this project, etc.)
Square brackets are meant for character class, and you're actually trying to match any one of: s, |, s (again), e, a, s (again), o and n.
Use parentheses instead for grouping:
(s|season)
or non-capturing group:
(?:s|season)
Note: Non-capture groups tell the engine that it doesn't need to store the match, while the other one (capturing group does). For small stuff, either works, for 'heavy duty' stuff, you might want to see first if you need the match or not. If you don't, better use the non-capture group to allocate more memory for calculation instead of storing something you will never need to use.
The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).
In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.
This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)
I am using Visual Studio 2013 & SQL Server 2014. I got the below error Microsoft.SqlServer.management.sdk.sfc version 11.0.0.0 not found by visual studio.
I was actually expecting Microsoft.SqlServer.management.sdk.sfc version 12.0.0.0 error because I am using SQL Server 2014.
To fix the issue, I had to install SQL Server 2012's SharedManagementObject.msi from the below site.

Connect android phone without using USB cable except XIAOMI PHONES
== MAKE SURE THAT YOUR PHONE HAS USB DEBUGGING ENABLED ==
== IP Address series should NOT be '0' like 192.168.0.10
1. Connect your PC (Laptop) and Android phone to same wifi network.
2. Go to the Android SDK folder > platform-tools and open command prompt by holding the shift key and right clicking on the folder.
3. Type the command "adb tcpip 5555", and hit Enter, sometimes it gives an error but ignore it and go ahead.
4. Type "adb connect [YOUR PHONE IP]". example: "adb connect 192.168.1.34" and hit enter, your phone will be connected to PC.
Much easier if u use bananas and a group of people.
Say you have 1 banana and group of 6 people, this you would express: 1 mod 6 / 1 % 6 / 1 modulo 6.
You need 6 bananas for each person in group to be well fed and happy.
So if you then have 1 banana and need to share it with 6 people, but you can only share if you have 1 banana for each group member, that is 6 persons, then you will have 1 banana (remainder, not shared on anyone in group), the same goes for 2 bananas. Then you will have 2 banana as remainder (nothing is shared).
But when you get 6 bananas, then you should be happy, because then there is 1 banana for each member in group of 6 people, and the remainder is 0 or no bananas left when you shared all 6 bananas on 6 people.
Now, for 7 bananas and 6 people in group, you then will have 7 mod 6 = 1, this because you gave 6 people 1 banana each, and 1 banana is the remainder.
For 12 mod 6 or 12 bananas shared on 6 people, each one will have two bananas, and the remainder is then 0.
You should use finish() when the user clicks on the button in order to go to the previous activity.
Button backButton = (Button)this.findViewById(R.id.back);
backButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
Alternatively, if you really need to, you can try to trigger your own back key press:
this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK));
this.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
Execute both of these.
A simple way using std::next_permutation:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.end() - r, v.end(), true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::next_permutation(v.begin(), v.end()));
return 0;
}
or a slight variation that outputs the results in an easier to follow order:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.begin(), v.begin() + r, true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::prev_permutation(v.begin(), v.end()));
return 0;
}
A bit of explanation:
It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.
You can implement it if you note that for each level r you select a number from 1 to n.
In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance
#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>
using namespace std;
struct combinations
{
typedef vector<int> combination_t;
// initialize status
combinations(int N, int R) :
completed(N < 1 || R > N),
generated(0),
N(N), R(R)
{
for (int c = 1; c <= R; ++c)
curr.push_back(c);
}
// true while there are more solutions
bool completed;
// count how many generated
int generated;
// get current and compute next combination
combination_t next()
{
combination_t ret = curr;
// find what to increment
completed = true;
for (int i = R - 1; i >= 0; --i)
if (curr[i] < N - R + i + 1)
{
int j = curr[i] + 1;
while (i <= R-1)
curr[i++] = j++;
completed = false;
++generated;
break;
}
return ret;
}
private:
int N, R;
combination_t curr;
};
int main(int argc, char **argv)
{
int N = argc >= 2 ? atoi(argv[1]) : 5;
int R = argc >= 3 ? atoi(argv[2]) : 2;
combinations cs(N, R);
while (!cs.completed)
{
combinations::combination_t c = cs.next();
copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
cout << endl;
}
return cs.generated;
}
test output:
1,2,
1,3,

There is a shorter way of doing this now:
exports.someValue = function(req, res, next) {
//query with mongoose
dbSchemas.SomeValue.find({}, 'name', function(err, someValue){
if(err) return next(err);
res.send(someValue);
});
//this eliminates the .select() and .exec() methods
};
In case you want most of the Schema fields and want to omit only a few, you can prefix the field name with a -. For ex "-name" in the second argument will not include name field in the doc whereas the example given here will have only the name field in the returned docs.

you can use a Scanner to read from input :
Scanner scanner = new Scanner(System.in);
char c = scanner.next().charAt(0); //charAt() method returns the character at the specified index in a string. The index of the first character is 0, the second character is 1, and so on.
You can try to re-set your Jenkins security:
config.xml with a text editor (i.e notepad++), maybe be in C:\jenkins\config.xml (could backup it also).<useSecurity>true</useSecurity> and change it to <useSecurity>false</useSecurity>You might create an admin user and enable security again.
There is also Scanner. You can use it just like the BufferedReader:
Scanner scanner = new Scanner(myString);
while (scanner.hasNextLine()) {
String line = scanner.nextLine();
// process the line
}
scanner.close();
I think that this is a bit cleaner approach that both of the suggested ones.
The ChildActionOnly attribute ensures that an action method can be called only as a child method
from within a view. An action method doesn’t need to have this attribute to be used as a child action, but
we tend to use this attribute to prevent the action methods from being invoked as a result of a user
request.
Having defined an action method, we need to create what will be rendered when the action is
invoked. Child actions are typically associated with partial views, although this is not compulsory.

I'm using react for an identity server so 'unsafe-inline' is not an option at all. If you look at your console and actually read the CSP docs, you might find that there are three options for solving the issue:
'unsafe-inline' as it says is unsafe if your project is using CSPs is for one reason and it is like throwing out the complete policy, will be the same to no have CSP policy at all
'sha-XXXCODE' this is good, safe but not optimal because there is a lot of manual work and every compilation the SHA might change so it will become easily a nightmare, use only when the script or style is unlikely to change and there are few references
Nonce. This is the winner!
Nonce works in the similar way as scripts
CSP HEADER ///csp stuff nonce-12331
<script nonce="12331">
//script content
</script>
Because the nonce in the csp is the same that the tag, the script will be executed
In the case of inline styles, the nonce also came in the form of attribute so the same rules apply.
so generate the nonce and put it on your inline scritps
If you are using webpack maybe you are using the style-loader
the following code will do the trick
module.exports = {
module: {
rules: [
{
test: /\.css$/i,
use: [
{
loader: 'style-loader',
options: {
attributes: {
nonce: '12345678',
},
},
},
'css-loader',
],
},
],
},
};
I was running into the same problem, here is how I got it working..
open terminal:
mkdir testExpress
cd testExpress
npm install request
or
sudo npm install -g request // If you would like to globally install.
now don't use
node app.js or node test.js, you will run into this problem doing so. You can also print the problem that is being cause by using this command.. "node -p app.js"
The above command to start nodeJs has been deprecated. Instead use
npm start
You should see this..
[email protected] start /Users/{username}/testExpress
node ./bin/www
Open your web browser and check for localhost:3000
You should see Express install (Welcome to Express)
First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.
if you need pass argument to update method you can do it like this
onClick={ (e) => this.props.onClick(e, 'home', 'Home') }
and get these arguments inside update method
update(e, space, txt){
console.log(e.target, space, txt);
}
event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset
<button
data-space="home"
className="home"
data-txt="Home"
onClick={ this.props.onClick }
/>
Button
</button>
onClick(e) {
console.log(e.target.dataset.txt, e.target.dataset.space);
}
Here is a function that takes as its arguments a DataFrame and a list of columns and coerces all data in the columns to numbers.
# df is the DataFrame, and column_list is a list of columns as strings (e.g ["col1","col2","col3"])
# dependencies: pandas
def coerce_df_columns_to_numeric(df, column_list):
df[column_list] = df[column_list].apply(pd.to_numeric, errors='coerce')
So, for your example:
import pandas as pd
def coerce_df_columns_to_numeric(df, column_list):
df[column_list] = df[column_list].apply(pd.to_numeric, errors='coerce')
a = [['a', '1.2', '4.2'], ['b', '70', '0.03'], ['x', '5', '0']]
df = pd.DataFrame(a, columns=['col1','col2','col3'])
coerce_df_columns_to_numeric(df, ['col2','col3'])
Here is the snippet worked in my case
final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
buildAlertMessageNoGps();
}
`
You can use any attribute as selector with [attribute_name=value].
$('td[name=tcol1]').hide();
Paint.NET will create and edit PNGs with gusto. It's an excellent program in many respects. It's free as in beer and speech.
Several answers above work. I wanted an approach that I did not have to keep making code changes and did not make my code unsecure. Hence I created a whitelist. Whitelist can be maintained in any datastore. I used config file since it is a very small list.
My code is below.
ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, error) => {
return error == System.Net.Security.SslPolicyErrors.None || certificateWhitelist.Contains(cert.GetCertHashString());
};
or
Any height or width will work
<style>
.list_container {
direction: rtl;
overflow:auto;
height: 50px;
width: 50px;
}
.item_direction {
direction:ltr;
}
</style>
<div class="list_container">
<div class="item_direction">1</div>
<div class="item_direction">2</div>
<div class="item_direction">3</div>
<div class="item_direction">4</div>
<div class="item_direction">5</div>
<div class="item_direction">6</div>
<div class="item_direction">7</div>
<div class="item_direction">8</div>
<div class="item_direction">9</div>
<div class="item_direction">10</div>
<div class="item_direction">11</div>
<div class="item_direction">12</div>
</div>
Optionally add class="item_direction to each item to change the direction of the text flow back, while preserving the container direction.
Use a packet sniffer like Wireshark to look at what happens. You need to see a SYN-flagged packet outgoing, a SYN+ACK-flagged incoming and then a ACK-flagged outgoing. After that, the port is considered open on the local side.
If you only see the first packet and the error message comes after several seconds of waiting, the other side is not answering at all (like in: unplugged cable, overloaded server, misguided packet was discarded) and your local network stack aborts the connection attempt. If you see RST packets, the host actually denies the connection. If you see "ICMP Port unreachable" or host unreachable packets, a firewall or the target host inform you of the port actually being closed.
Of course you cannot expect the service to be available at all times (consider all the points of failure in between you and the data), so you should try again later.
I was parsing JSON from a REST API call and got this error. It turns out the API had become "fussier" (eg about order of parameters etc) and so was returning malformed results. Check that you are getting what you expect :)
Kotlin extensions for Long and ByteArray types:

To summarize the other answers, for general use:
if [ foo ]; then
a; b
elif [ bar ]; then
c; d
else
e; f
fi
if [ foo ]; then a && b; elif [ bar ]; c && d; else e && f; fi
( foo && a && b ) || ( bar && c && d ) || e && f;
Remember that the AND and OR operators evaluate whether or not the result code of the previous operation was equal to true/success (0). So if a custom function returns something else (or nothing at all), you may run into problems with the AND/OR shorthand. In such cases, you may want to replace something like ( a && b ) with ( [ a == 'EXPECTEDRESULT' ] && b ), etc.
Also note that ( and [ are technically commands, so whitespace is required around them.
Instead of a group of && statements like then a && b; else, you could also run statements in a subshell like then $( a; b ); else, though this is less efficient. The same is true for doing something like result1=$( foo; a; b ); result2=$( bar; c; d ); [ "$result1" -o "$result2" ] instead of ( foo && a && b ) || ( bar && c && d ). Though at that point you'd be getting more into less-compact, multi-line stuff anyway.
I prefer the lambda form of the DropDownList helper - see MVC 3 Layout Page, Razor Template, and DropdownList

You can put CSS in the head of the HTML file, and it will take precedent over a class in an included style sheet.

Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.
In jQuery:
$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })
In plain vanilla javaScript (from w3c):
var xmlhttp;
function loadXMLDoc(url)
{
xmlhttp=null;
if (window.XMLHttpRequest)
{// code for all new browsers
xmlhttp=new XMLHttpRequest();
}
else if (window.ActiveXObject)
{// code for IE5 and IE6
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
if (xmlhttp!=null)
{
xmlhttp.onreadystatechange=state_Change;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}
else
{
alert("Your browser does not support XMLHTTP.");
}
}
function state_Change()
{
if (xmlhttp.readyState==4)
{// 4 = "loaded"
if (xmlhttp.status==200)
{// 200 = OK
//xmlhttp.data and shtuff
// ...our code here...
}
else
{
alert("Problem retrieving data");
}
}
}
If you are only concerned with getting an integer value out of a whole floating point number (i.e. 12347.9999 or 54321.0001), this approach (borrowed and modified from above) will do the trick:
my $rounded = floor($float + 0.1);
I m using android studio 3.0 and i upgrade the design pattern dependency from 26.0.1 to 27.1.1 and the error is gone now.
Add Following in gradle
implementation 'com.android.support:design:27.1.1'
If you want all packages in that repository, use ... to signify that, like:
go get code.google.com/p/go.text/...
for error : pyodbc.InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
No space between the driver and event
connection = Driver={SQL Server Native Client 11.0};
"Server=servername;"
"Database=dbname;"
"Trusted_Connection=yes;"
Relative path:
ConnectionString = "Data Source=|DataDirectory|\Database.sdf";
Modifying DataDirectory as executable's path:
string executable = System.Reflection.Assembly.GetExecutingAssembly().Location;
string path = (System.IO.Path.GetDirectoryName(executable));
AppDomain.CurrentDomain.SetData("DataDirectory", path);
I was hung up on this because I was specifying my public key file in
scp -i [private key file path]
When I caught that mistake and changed it to the private key path instead, I was all set.
Go to the source folder where your project is.
->Settings.gradle.':your new project name 'I didn't want to make the new page unless the callback returned successfully, so I did this to simulate the user click:
function submitAndRedirect {
apiCall.then(({ redirect }) => {
const a = document.createElement('a');
a.href = redirect;
a.target = '_blank';
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
});
}
Um, why not just:
>>>> import os
>>>> os.path.join(dir_name, base_filename + "." + format)
'/home/me/dev/my_reports/daily_report.pdf'
If you have a hidden field like this
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("VertragNr") %>'/>
Now you can use your value like this
$(this).parent().find('input[type=hidden]').val()
Date and time formats are well described below
SimpleDateFormat (Java Platform SE 7) - Date and Time Patterns
There could be n Number of formats you can possibly make. ex - dd/MM/yyyy or YYYY-'W'ww-u or you can mix and match the letters to achieve your required pattern. Pattern letters are as follow.
G - Era designator (AD)y - Year (1996; 96)Y - Week Year (2009; 09)M - Month in year (July; Jul; 07)w - Week in year (27)W - Week in month (2)D - Day in year (189)d - Day in month (10)F - Day of week in month (2)E - Day name in week (Tuesday; Tue)u - Day number of week (1 = Monday, ..., 7 = Sunday)a - AM/PM markerH - Hour in day (0-23)k - Hour in day (1-24)K - Hour in am/pm (0-11)h - Hour in am/pm (1-12)m - Minute in hour (30)s - Second in minute (55)S - Millisecond (978)z - General time zone (Pacific Standard Time; PST; GMT-08:00)Z - RFC 822 time zone (-0800)X - ISO 8601 time zone (-08; -0800; -08:00)To parse:
2000-01-23T04:56:07.000+0000
Use:
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
In C# there's no 'new line' character like there is in VB.NET. The end of a logical 'line' of code is denoted by a ';'. If you wish to break the line of code over multiple lines, just hit the carriage return (or if you want to programmatically add it (for programmatically generated code) insert 'Environment.NewLine' or '\r\n'.
Edit: In response to your comment: If you wish to break a string over multiple lines (i.e. programmatically), you should insert the Environment.NewLine character. This will take the environment into account in order to create the line ending. For instance, many environments, including Unix/Linux only use a NewLine character (\n), but Windows uses both carriage return and line feed (\r\n). So to break a string you would use:
string output = "Hello this is my string\r\nthat I want broken over multiple lines."
Of course, this would only be good for Windows, so before I get flamed for incorrect practice you should actually do this:
string output = string.Format("Hello this is my string{0}that I want broken over multiple lines.", Environment.NewLine);
Or if you want to break over multiple lines in your IDE, you would do:
string output = "My string"
+ "is split over"
+ "multiple lines";
If you could provide some reason as to why you need to replace the label with a div, that would certainly help...
Also, could you paste a sample that'd be helpful ( http://dpaste.com/ or http://pastebin.com/)
I tried many GUI's, and the best for me continue being "SQLyog-comunity" by using wine. Is complete, is nice, and is intuitive. (and in wine work perfect)
Your database name must end with .db also your query strings must have a terminator (;)
The function export_fig on the MATLAB file exchange will crop the whitespace around an output PDF/EPS file by default when it exports a figure.
You indicated that you're using Angular 1.2.0... as one of the other comments indicated, ng-bind-html-unsafe has been deprecated.
Instead, you'll want to do something like this:
<div ng-bind-html="preview_data.preview.embed.htmlSafe"></div>
In your controller, inject the $sce service, and mark the HTML as "trusted":
myApp.controller('myCtrl', ['$scope', '$sce', function($scope, $sce) {
// ...
$scope.preview_data.preview.embed.htmlSafe =
$sce.trustAsHtml(preview_data.preview.embed.html);
}
Note that you'll want to be using 1.2.0-rc3 or newer. (They fixed a bug in rc3 that prevented "watchers" from working properly on trusted HTML.)
You should covert String to float. It is working.
float result = 0;
if (TextUtils.isEmpty(et.getText().toString()) {
return;
}
result = Float.parseFloat(et.getText().toString());
tv.setText(result);
Internet Explorer (IE8 and lower) doesn't support addEventListener(...). It has its own event model using the attachEvent method. You could use some code like this:
var element = document.getElementById('container');
if (document.addEventListener){
element .addEventListener('copy', beforeCopy, false);
} else if (el.attachEvent){
element .attachEvent('oncopy', beforeCopy);
}
Though I recommend avoiding writing your own event handling wrapper and instead use a JavaScript framework (such as jQuery, Dojo, MooTools, YUI, Prototype, etc) and avoid having to create the fix for this on your own.
By the way, the third argument in the W3C model of events has to do with the difference between bubbling and capturing events. In almost every situation you'll want to handle events as they bubble, not when they're captured. It is useful when using event delegation on things like "focus" events for text boxes, which don't bubble.
The document.write method is very limited. You can only use it before the page has finished loading. You can't use it to update the contents of a loaded page.
What you probably want is innerHTML.
You could also do it with a Func like this
@{
var getStyle = new Func<int, int, string>((width, margin) => string.Format("width: {0}px; margin: {1}px;", width, margin));
}
<div style="@getStyle(50, 2)"></div>
To augment LazyOne's answer, here is an annotated version of the answer.
<rewrite>
<rules>
<clear />
<rule name="Redirect all requests to https" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll">
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action
type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}"
redirectType="Permanent" appendQueryString="false" />
</rule>
</rules>
</rewrite>
Clear all the other rules that might already been defined on this server. Create a new rule, that we will name "Redirect all requests to https". After processing this rule, do not process any more rules! Match all incoming URLs. Then check whether all of these other conditions are true: HTTPS is turned OFF. Well, that's only one condition (but make sure it's true). If it is, send a 301 Permanent redirect back to the client at http://www.foobar.com/whatever?else=the#url-contains. Don't add the query string at the end of that, because it would duplicate the query string!
This is what the properties, attributes, and some of the values mean.
MatchAll) or any of the conditions must be true (MatchAny); similar to AND vs OR. match and its conditions are all true.
redirect (client-side) or rewrite (server-side). https:// with two server variables.url or not; in this case, we are setting it to false, because the {REQUEST_URI} already includes it.The server variables are

No packages needed:
String paddedString = i < 100 ? i < 10 ? "00" + i : "0" + i : "" + i;
This will pad the string to three characters, and it is easy to add a part more for four or five. I know this is not the perfect solution in any way (especially if you want a large padded string), but I like it.
Below code worked for me:
string _stDate = Convert.ToDateTime(DateTime.Today.AddMonths(-12)).ToString("MM/dd/yyyy");
String format ="MM/dd/yyyy";
IFormatProvider culture = new System.Globalization.CultureInfo("fr-FR", true);
DateTime _Startdate = DateTime.ParseExact(_stDate, format, culture);
If you only want to remove the last commit from the remote repository without messing up with your local repository, here's a one-liner:
git push origin +origin/master~:master
This uses the following syntax:
git push <remote> <refspec>
Here, <remote> is origin, and <refspec> has the following structure:
+origin/master~:master
Details can be found in git-push(1). The preceding + means "force push this ref", and the other part means "from origin/master~ to master (of remote origin)". It isn't hard to know that origin/master~ is the last commit before origin/master, right?
I'd like to supplement BalusC's answer with the mapping rules and an example.
Mapping rules from Servlet 2.5 specification:
In our example, there're three servlets. / is the default servlet installed by us. Tomcat installs two servlets to serve jsp and jspx. So to map http://host:port/context/hello
To map http://host:port/context/hello.jsp
var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;
if (!isNaN(top)) {
$("#app_scroler").click(function () {
$('html, body').animate({
scrollTop: top
}, 100);
});
}
if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800
var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;
An array is a pointer. It points to the start of a sequence of "objects".
If we do this: ìnt arr[10];, then arr is a pointer to a memory location, from which ten integers follow. They are uninitialised, but the memory is allocated. It is exactly the same as doing int *arr = new int[10];.
Swift 3.1
func fixImageOrientation(_ image: UIImage)->UIImage {
UIGraphicsBeginImageContext(image.size)
image.draw(at: .zero)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage ?? image
}
In my opinion, the only proper answer to this question is to try to use the path and let the OS and filesystem validate it. Otherwise you are just reimplementing (and probably poorly) all the validation rules that the OS and filesystem already use and if those rules are changed in the future you will have to change your code to match them.
You can launch any command line program using the Process class, and set the StandardOutput property of the Process instance with a stream reader you create (either based on a string or a memory location). After the process completes, you can then do whatever diff you need to on that stream.
Now, this seems to work:
$('#example').DataTable({
"info": false
});
it hides that div, altogether
If Khanh TO's solution caused UI issues for you (like it did for me) try using $timeout to not update the attribute until it has been unchanged for 500ms.
var oldWidth = window.innerWidth;
$(window).on('resize.doResize', function () {
var newWidth = window.innerWidth,
updateStuffTimer;
if (newWidth !== oldWidth) {
$timeout.cancel(updateStuffTimer);
}
updateStuffTimer = $timeout(function() {
updateStuff(newWidth); // Update the attribute based on window.innerWidth
}, 500);
});
$scope.$on('$destroy',function (){
$(window).off('resize.doResize'); // remove the handler added earlier
});

To search for multiple matches in each file, we can sequence several Select-String calls:
Get-ChildItem C:\Logs |
where { $_ | Select-String -Pattern 'VendorEnquiry' } |
where { $_ | Select-String -Pattern 'Failed' } |
...
At each step, files that do not contain the current pattern will be filtered out, ensuring that the final list of files contains all of the search terms.
Rather than writing out each Select-String call manually, we can simplify this with a filter to match multiple patterns:
filter MultiSelect-String( [string[]]$Patterns ) {
# Check the current item against all patterns.
foreach( $Pattern in $Patterns ) {
# If one of the patterns does not match, skip the item.
$matched = @($_ | Select-String -Pattern $Pattern)
if( -not $matched ) {
return
}
}
# If all patterns matched, pass the item through.
$_
}
Get-ChildItem C:\Logs | MultiSelect-String 'VendorEnquiry','Failed',...
Now, to satisfy the "Logtime about 11:30 am" part of the example would require finding the log time corresponding to each failure entry. How to do this is highly dependent on the actual structure of the files, but testing for "about" is relatively simple:
function AboutTime( [DateTime]$time, [DateTime]$target, [TimeSpan]$epsilon ) {
$time -le ($target + $epsilon) -and $time -ge ($target - $epsilon)
}
PS> $epsilon = [TimeSpan]::FromMinutes(5)
PS> $target = [DateTime]'11:30am'
PS> AboutTime '11:00am' $target $epsilon
False
PS> AboutTime '11:28am' $target $epsilon
True
PS> AboutTime '11:35am' $target $epsilon
True
You have empty $entry_database variable. As you see in error: ListEmail, Title FROM WHERE ID bewteen FROM and WHERE should be name of table. Proper syntax of SELECT:
SELECT columns FROM table [optional things as WHERE/ORDER/GROUP/JOIN etc]
which in your way should become:
SELECT ID, ListStID, ListEmail, Title FROM some_table_you_got WHERE ID = '4'
You could simply use echo on and you will see that goto :eof or even exit /b doesn't work as expected.
The code inside of the loop isn't executed anymore, but the loop is expanded for all numbers to the end.
That's why it's so slow.
The only way to exit a FOR /L loop seems to be the variant of exit like the exsample of Wimmel, but this isn't very fast nor useful to access any results from the loop.
This shows 10 expansions, but none of them will be executed
echo on
for /l %%n in (1,1,10) do (
goto :eof
echo %%n
)
x.times do |i|
something(i+1)
end
For substracting in moment.js:
moment().subtract(1, 'months').format('MMM YYYY');
Documentation:
http://momentjs.com/docs/#/manipulating/subtract/
Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).
moment().subtract('seconds', 1); // Deprecated in 2.8.0
moment().subtract(1, 'seconds');
As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.
moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8
Using dplyr (a bit like sapply..)

I use SQLYog at home and work. It turns out they DO have a free open-source version, though sadly they've been trying to hide that fact for the last few years.
You can download the open-source version from https://github.com/webyog/sqlyog-community - just click the "Download SQLyog Community Version" link.
Put this bean in your configuration class.
@Bean
public Validator localValidatorFactoryBean() {
return new LocalValidatorFactoryBean();
}
and then You can use
<T> BindingResult validate(T t) {
DataBinder binder = new DataBinder(t);
binder.setValidator(validator);
binder.validate();
return binder.getBindingResult();
}
for validating a bean manually. Then You will get all result in BindingResult and you can retrieve from there.

It's the special table in Oracle. I often use it for calculations or checking system variables. For example:
Select 2*4 from dual prints out the result of the calculationSelect sysdate from dual prints the server current date. Native methods allow you to use code from other languages such as C or C++ in your java code. You use them when java doesn't provide the functionality that you need. For example, if I were writing a program to calculate some equation and create a line graph of it, I would use java, because it is the language I am best in. However, I am also proficient in C. Say in part of my program I need to calculate a really complex equation. I would use a native method for this, because I know some C++ and I know that C++ is much faster than java, so if I wrote my method in C++ it would be quicker. Also, say I want to interact with another program or device. This would also use a native method, because C++ has something called pointers, which would let me do that.
The = means bi-directional binding, so a reference to a variable to the parent scope. This means, when you change the variable in the directive, it will be changed in the parent scope as well.
@ means the variable will be copied (cloned) into the directive.
As far as I know, <pane bi-title="{{title}}" title="{{title}}">{{text}}</pane> should work too. bi-title will receive the parent scope variable value, which can be changed in the directive.
If you need to change several variables in the parent scope, you could execute a function on the parent scope from within the directive (or pass data via a service).
You're declaring (some of) your event handlers incorrectly:
$('.menuOption').click(function( event ){ // <---- "event" parameter here
event.preventDefault();
var categories = $(this).attr('rel');
$('.pages').hide();
$(categories).fadeIn();
});
You need "event" to be a parameter to the handlers. WebKit follows IE's old behavior of using a global symbol for "event", but Firefox doesn't. When you're using jQuery, that library normalizes the behavior and ensures that your event handlers are passed the event parameter.
edit — to clarify: you have to provide some parameter name; using event makes it clear what you intend, but you can call it e or cupcake or anything else.
Note also that the reason you probably should use the parameter passed in from jQuery instead of the "native" one (in Chrome and IE and Safari) is that that one (the parameter) is a jQuery wrapper around the native event object. The wrapper is what normalizes the event behavior across browsers. If you use the global version, you don't get that.

My Environment:
Angular CLI Global : 6.0.0, Local: 1.7.4, Angular: 5.2, Typescript 2.5.3
Note: To enable
ng Updateyou need to install Angular CLI 6.0 firstnpm install -g @angular/cli or npm install @angular/cli
ng update //update Angular Package core/common/complier... to 6.0.0
ng update @angular/cli //change angular-cli.json to angular.json
optional if you have angular-material 5.4.2, ngx-translate 9.1.1, ng-bootstrap/ng-bootstrap 1.1.1:
ng update @angular/material //upgrade to 6.0.1
npm install @ngx-translate/[email protected] --save //upgrade ngX translate to 10.0.1 for Angular 6
5 npm install --save @ng-bootstrap/[email protected] //for ng-bootstrap
If you use Observable and get the error:
ERROR in node_modules/rxjs/Observable.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/Observable'. node_modules/rxjs/observable/of.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/observable/of'.
Change: import { Observable } from "rxjs/Observable"; import { of } from 'rxjs/observable/of';
To
import { Observable, of } from "rxjs";

This code implements the logic of how search works (one of the ways) without using any ready-made function:
public int findSubString(char[] original, char[] searchString)
{
int returnCode = 0; //0-not found, -1 -error in imput, 1-found
int counter = 0;
int ctr = 0;
if (original.Length < 1 || (original.Length)<searchString.Length || searchString.Length<1)
{
returnCode = -1;
}
while (ctr <= (original.Length - searchString.Length) && searchString.Length > 0)
{
if ((original[ctr]) == searchString[0])
{
counter = 0;
for (int count = ctr; count < (ctr + searchString.Length); count++)
{
if (original[count] == searchString[counter])
{
counter++;
}
else
{
counter = 0;
break;
}
}
if (counter == (searchString.Length))
{
returnCode = 1;
}
}
ctr++;
}
return returnCode;
}
Use stream to write content to webrequest
string data = "username=<value>&password=<value>"; //replace <value>
byte[] dataStream = Encoding.UTF8.GetBytes(data);
private string urlPath = "http://xxx.xxx.xxx/manager/";
string request = urlPath + "index.php/org/get_org_form";
WebRequest webRequest = WebRequest.Create(request);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = dataStream.Length;
Stream newStream=webRequest.GetRequestStream();
// Send the data.
newStream.Write(dataStream,0,dataStream.Length);
newStream.Close();
WebResponse webResponse = webRequest.GetResponse();
simple is the best and works in every version.

I had a slightly different problem. I worked with inputs in a modal and it drove me mad. No of the proposed solutions worked for me.
Until i found this issue: https://github.com/valor-software/ngx-bootstrap/issues/1597
This good guy gave me the hint that ngx-bootstrap modal has a focus configuration. If this configuration is not set to false, the modal will be focused after the animation and there is NO WAY to focus anything else.
Update:
To set this configuration, add the following attribute to the modal div:
[config]="{focus: false}"
Update 2:
To force the focus on the input field i wrote a directive and set the focus in every AfterViewChecked cycle as long as the input field has the class ng-untouched.
ngAfterViewChecked() {
// This dirty hack is needed to force focus on an input element of a modal.
if (this.el.nativeElement.classList.contains('ng-untouched')) {
this.renderer.invokeElementMethod(this.el.nativeElement, 'focus', []);
}
}
