I am now able to successfully build. Not sure exactly which step "fixed" things, but this was the sequence:
While I am not sure exactly which parts were necessary, I think the previous certificates were the problem. I hate Xcode :(
Thanks for help.
In my case, I already was signed in. So I had to sign out
and sign in
again.

You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:
import seaborn as sns
tips = sns.load_dataset("tips")
b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()
, which results in this:
To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.
NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.
Use app:itemIconTint in your NavigationView, ej:
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:itemTextColor="@color/customColor"
app:itemIconTint="@color/customColor"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_home"
app:menu="@menu/activity_home_drawer" />
It supports after KITKAT. Just add following code inside onCreate method of your Activity. No need any modifications to Manifest file.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow(); // in Activity's onCreate() for instance
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

df = pd.DataFrame([{'Product': 'Coke', 'Prices': [100,123,101,105,99,94,98]},{'Product': 'Pepsi', 'Prices': [101,104,104,101,99,99,99]}])
print(df)
df = df.assign(Prices=df.Prices.str.split(',')).explode('Prices')
print(df)
Try this in pandas >=0.25 version
Not sure about older versions, but in 2016.2 removing the .key

I'm using my JetBrains account and used the 'Remove License' button found at the bottom of the registration dialog. You can find this under the Help
menu or from the startup dialog via Configure -> Manage License...
.
Though this isn't a DIRECT answer to your question, I just encountered a similar problem, and thought I'd mentioned it:
I had an instance where it was instantiating a new (no doubt very inefficent) record for data.frame (a result of recursive searching) and it was giving me the same error.
I had this:
return(
data.frame(
user_id = gift$email,
sourced_from_agent_id = gift$source,
method_used = method,
given_to = gift$account,
recurring_subscription_id = NULL,
notes = notes,
stringsAsFactors = FALSE
)
)
turns out... it was the = NULL. When I switched to = NA, it worked fine. Just in case anyone else with a similar problem hits THIS post as I did.
The POSIX specification for find says:
-mtime
n
The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), isn
.
Interestingly, the description of find
does not further specify 'initialization time'. It is probably, though, the time when find
is initialized (run).
In the descriptions, wherever
n
is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a plus ( '+' ) or minus-sign ( '-' ) sign, as follows:
+n
More thann
.
n
Exactlyn
.
-n
Less thann

At the given time (2014-09-01 00:53:44 -4:00, where I'm deducing that AST is Atlantic Standard Time, and therefore the time zone offset from UTC is -4:00 in ISO 8601 but +4:00 in ISO 9945 (POSIX), but it doesn't matter all that much):
1409547224 = 2014-09-01 00:53:44 -04:00
1409457540 = 2014-08-30 23:59:00 -04:00
so:
1409547224 - 1409457540 = 89684
89684 / 86400 = 1
Even if the 'seconds since the epoch' values are wrong, the relative values are correct (for some time zone somewhere in the world, they are correct).
The n
value calculated for the 2014-08-30 log file therefore is exactly 1
(the calculation is done with integer arithmetic), and the +1
rejects it because it is strictly a > 1
comparison (and not >= 1
).
You cannot concatenate raw strings like this. operator+
only works with two std::string
objects or with one std::string
and one raw string (on either side of the operation).
std::string s("...");
s + s; // OK
s + "x"; // OK
"x" + s; // OK
"x" + "x" // error
The easiest solution is to turn your raw string into a std::string
first:
"Do you feel " + std::string(AGE) + " years old?";
Of course, you should not use a macro in the first place. C++ is not C. Use const
or, in C++11 with proper compiler support, constexpr
.
I solved this, without having to completely reinstall Visual Studio 2013.
For those who may come across this in the future, the following steps worked for me:
vs_professional.exe
).If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3
Click the link for 'examine the log file' and look near the bottom of the log, for this line:
open regedit.exe
and do an Edit > Find...
for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
. This was found in:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
Edit the BundleVersion
value and change it to a lower version. I changed mine from 12.0.21005.13
to 12.0.21000.13
:
Exit the registry
Run the ISO (or vs_professional.exe
) again. If it has a repair button like the image below, you can skip to step 4.
Run the ISO (or vs_professional.exe
) again. This time repair should be visible.
Click Repair
and let it update your installation and apply its embedded license key. This took about 20 minutes.
Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product
:
Hope this helps somebody in the future!
Here is a small test that demonstrates that feeding the seed()
method with the same argument will cause the same pseudo-random result:
# testing random.seed()
import random
def equalityCheck(l):
state=None
x=l[0]
for i in l:
if i!=x:
state=False
break
else:
state=True
return state
l=[]
for i in range(1000):
random.seed(10)
l.append(random.random())
print "All elements in l are equal?",equalityCheck(l)
You can use __halt_compiler
function which will Halt the compiler execution
Your error is in UpdaterServiceManager in onCreate and showNotification method.
You are trying to show notification
from Service using Activity Context
. Whereas Every Service has its own Context,
just use the that. You don't need to pass a Service an Activity's Context.
I don't see why you need a specific Activity's Context to show Notification.
Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.
You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference
As @cs95 mentioned in a comment, to drop only one level, use:
df.reset_index(level=[...])
This avoids having to redefine your desired index after reset.
You need to open the project file of your program and it should appear on Management panel.
Right click on the project file, then select add file. You should add the 3 source code (secrypt.h, secrypt.cpp, and the trial.cpp)
Compile and enjoy. Hope, I could help you.
This is an old school approach, but if you're performing an iterative update or insert operation in SQL, something that runs for a long time, it's a good idea to periodically (programmatically) call "checkpoint". Calling "checkpoint" causes SQL to write to disk all of those memory-only changes (dirty pages, they're called) and items stored in the transaction log. This has the effect of cleaning out your transaction log periodically, thus preventing problems like the one described.
Just use
string.Join(",", yourCollection)
This way you don't need the StringBuilder
and the loop.
Long addition about async case. As of 2019, it's not a rare setup when the data are coming asynchronously.
In case your data are in async collection, there is no string.Join
overload taking IAsyncEnumerable<T>
. But it's easy to create one manually, hacking the code from string.Join
:
public static class StringEx
{
public static async Task<string> JoinAsync<T>(string separator, IAsyncEnumerable<T> seq)
{
if (seq == null)
throw new ArgumentNullException(nameof(seq));
await using (var en = seq.GetAsyncEnumerator())
{
if (!await en.MoveNextAsync())
return string.Empty;
string firstString = en.Current?.ToString();
if (!await en.MoveNextAsync())
return firstString ?? string.Empty;
// Null separator and values are handled by the StringBuilder
var sb = new StringBuilder(256);
sb.Append(firstString);
do
{
var currentValue = en.Current;
sb.Append(separator);
if (currentValue != null)
sb.Append(currentValue);
}
while (await en.MoveNextAsync());
return sb.ToString();
}
}
}
If the data are coming asynchronously but the interface IAsyncEnumerable<T>
is not supported (like the mentioned in comments SqlDataReader
), it's relatively easy to wrap the data into an IAsyncEnumerable<T>
:
async IAsyncEnumerable<(object first, object second, object product)> ExtractData(
SqlDataReader reader)
{
while (await reader.ReadAsync())
yield return (reader[0], reader[1], reader[2]);
}
and use it:
Task<string> Stringify(SqlDataReader reader) =>
StringEx.JoinAsync(
", ",
ExtractData(reader).Select(x => $"{x.first} * {x.second} = {x.product}"));
In order to use Select
, you'll need to use nuget package System.Interactive.Async
. Here you can find a compilable example.
I suggest also checking how much memory is currently being used.
It turns out that the inability to find these DLL files was the first symptom exhibited when trying to run a program (either run or debug) in Visual Studio.
After over a half hour with much head scratching, searching the web, running Process Monitor, and Task Manager, and depends, a completely different program that had been running since the beginning of time reported that "memory is low; try stopping some programs" or some such. After killing Firefox, Thunderbird, Process Monitor, and depends, everything worked again.
Scaling to double and bringing down to half with zoom
worked for me.
transform: scale(2);
zoom: 0.5;
Just a follow up to @LisaD's answer.
As of 2016 (Django 1.9
), you need to type:
heroku pg:reset DATABASE_URL
heroku run python manage.py makemigrations
heroku run python manage.py migrate
This will give you a fresh new database within Heroku.
subList function is a trick, the returned object is still in the original list. so if you do any operation in subList, it will cause the concurrent exception in your code, no matter it is single thread or multi thread.

I got around this by finding the nuget.exe and moving to an easy to type path (c:\nuget\nuget) and then calling the nuget with this path. This seems to solve the problem. c:\nuget\nuget at the package manager console works as expected. I tried to find the path that the console was using and changing the environment path but was never able to get it to work in that way.
If you want to use the numbers
method, you need an int array to store the returned value.
public static void main(String[] args){
int[] someNumbers = numbers();
//do whatever you want with them...
System.out.println(Arrays.toString(someNumbers));
}
Right click on the file with file explorer, choose Properties

If path is not hardcoded in any script then your websites should work seamlessly.
The account which is running the service might not have mapped the D:-drive (they are user-specific). Try sharing the directory, and use full UNC-path in your backupConfig

Your watcher
of type FileSystemWatcher
is a local variable, and is out of scope when the OnStart
method is done. You probably need it as an instance or class variable.
I found the answer in pure sed supplied by this question (admittedly, posted after this question was posted). This does exactly what you asked, solely in sed:
result=\`echo "$pid" | sed '/./ { s/pid:\ //g; }'\``
The dot in sed '/./
) is whatever you want to match. Your question is exactly what I was attempting to, except in my case I wanted to match a specific line in a file and then uncomment it. In my case it was:
# Uncomment a line (edit the file in-place):
sed -i '/#\ COMMENTED_LINE_TO_MATCH/ { s/#\ //g; }' /path/to/target/file
The -i
after sed
is to edit the file in place (remove this switch if you want to test your matching expression prior to editing the file).
(I posted this because I wanted to do this entirely with sed as this question asked and none of the previous answered solved that problem.)
I ran into a similar problem where I was trying to sort a n x 2 2D array
named contests
which is a 2D array of simple integers. This was working for most of the times but threw a runtime error for one input:-
Arrays.sort(contests, (row1, row2) -> {
if (row1[0] < row2[0]) {
return 1;
} else return -1;
});
Error:-

Looking at the answers above I tried adding a condition for equals
and I don't know why but it worked. Hopefully we must explicitly specify what should be returned for all cases (greater than, equals and less than):
Arrays.sort(contests, (row1, row2) -> {
if (row1[0] < row2[0]) {
return 1;
}
if(row1[0] == row2[0]) return 0;
return -1;
});
Another alternative to cut, copy and paste emojis is:
My own solution on Linux (under ~/.config/smartgit/19.1
) is to comment or remove line listx
from preferences.yml
file and reopen program.
Deleting the all folders will make you reconfigure everything (useless).
For me the solution was to fix the output directory under project settings. Before I was using just "target" for the Project compiler output. Instead I updated it to have a full path e.g. D:\dev\sigplusjava2_68\target
You're right that you should use the Dispatcher
to update controls on the UI thread, and also right that long-running processes should not run on the UI thread. Even if you run the long-running process asynchronously on the UI thread, it can still cause performance issues.
It should be noted that Dispatcher.CurrentDispatcher
will return the dispatcher for the current thread, not necessarily the UI thread. I think you can use Application.Current.Dispatcher
to get a reference to the UI thread's dispatcher if that's available to you, but if not you'll have to pass the UI dispatcher in to your background thread.
Typically I use the Task Parallel Library for threading operations instead of a BackgroundWorker
. I just find it easier to use.
For example,
Task.Factory.StartNew(() =>
SomeObject.RunLongProcess(someDataObject));
where
void RunLongProcess(SomeViewModel someDataObject)
{
for (int i = 0; i <= 1000; i++)
{
Thread.Sleep(10);
// Update every 10 executions
if (i % 10 == 0)
{
// Send message to UI thread
Application.Current.Dispatcher.BeginInvoke(
DispatcherPriority.Normal,
(Action)(() => someDataObject.ProgressValue = (i / 1000)));
}
}
}
Just try to run the following command manually:
C:\wamp\bin\mysql\mysql5.6.17\bin\mysqld.exe --console
It worked for me :)
I have also come across the same issue and figuredout the issue here is the solution.
Lot of people assumes Eclipse and maven intergration is tough but its very eassy.
1) download the maven and unzip it in to your favorite directory.
Ex : C:\satyam\DEV_TOOLS\apache-maven-3.1.1
2) Set the environment variable for Maven(Hope every one knows where to go to set this)
In the system variable: Variable_name = M2_HOME Variable_Value =C:\satyam\DEV_TOOLS\apache-maven-3.1.1
Next in the same System Variable you will find the variable name called Path: just edit the path variable and add M2_HOME details like with the existing values.
%M2_HOME%/bin;
so in the second step now you are done setting the Maven stuff to your system.you need to cross check it whether your setting is correct or not, go to command prompt and type mvn--version it should disply the path of your Maven
3) Open the eclipse and go to Install new software and type M2E Plugin install and restart the Eclipse
with the above 3 steps you are done with Maven and Maven Plugin with eclipse
4) Maven is used .m2 folder to download all the jars, it will find in Ex: C:\Users\tempsakat.m2
under this folder one settings.xml file and one repository folder will be there
5) go to Windwo - preferences of your Eclipse and type Maven then select UserSettings from left menu then give the path of the settings.xml here .
now you are done...
void intSwap (int *pa, int *pb){
int temp = *pa;
*pa = *pb;
*pb = temp;
}
You need to know the following -
int a = 5; // an integer, contains value
int *p; // an integer pointer, contains address
p = &a; // &a means address of a
a = *p; // *p means value stored in that address, here 5
void charSwap(char* a, char* b){
char temp = *a;
*a = *b;
*b = temp;
}
So, when you swap like this. Only the value will be swapped. So, for a char*
only their first char
will swap.
Now, if you understand char* (string) clearly, then you should know that, you only need to exchange the pointer. It'll be easier to understand if you think it as an array
instead of string.
void stringSwap(char** a, char** b){
char *temp = *a;
*a = *b;
*b = temp;
}
So, here you are passing double pointer because starting of an array
itself is a pointer.
If you want to find out only whether or not the files are identical, you can use the Windows fc
command in binary mode:
fc.exe /b file1 file2
For details, see the reference for fc
I've found the solution :
You have to add the html5=1
in the src attribute of the iframe :
<iframe src="http://www.youtube.com/embed/dP15zlyra3c?html5=1"></iframe>
The video will be displayed as HTML5 if available, or fallback into flash player.
Try replaceAll("\\\\", "")
or replaceAll("\\\\/", "/")
.
The problem here is that a backslash is (1) an escape chararacter in Java string literals, and (2) an escape character in regular expressions – each of this uses need doubling the character, in effect needing 4 \
in row.
Of course, as Bozho said, you need to do something with the result (assign it to some variable) and not throw it away. And in this case the non-regex variant is better.

Came across this old thread searching for a similar solution myself and found the accepted answer to be using .complete()
method of jquery ajax
. I quote the notice on jquery website here:
The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.
To know the status code
of a ajax response, one can use the following code:
$.ajax( url [, settings ] )
.always(function (jqXHR) {
console.log(jqXHR.status);
});
Works similarily for .done()
and .fail()
My take is a combination of a couple of posted answers, with some modifications to make them easier to use from within a running python environment.
The idea is to provide a entirely new command (modeled after the install command) that gives you an instance of the package finder to use. The upside is that it works with, and uses, any indexes that pip supports and reads your local pip configuration files, so you get the correct results as you would with a normal pip install.
I've made an attempt at making it compatible with both pip v 9.x and 10.x.. but only tried it on 9.x

I had the exact same problem. The problem was that Anaconda had not registered Python in the windows registry.
1) pip install pywin
2) execute this script to register Python in the windows registry
3) download the appropriate package form Corey Goldberg's answer and python will be detected
If you want to change background color, try this:
plt.rcParams['figure.facecolor'] = 'white'
If you already have a test class, but missing the JUnit library dependency, please refer to Configuring Libraries for Unit Testing documentation section. Pressing Alt+Enter on the red code should give you an intention action to add the missing jar.
However, IDEA offers much more. If you don't have a test class yet and want to create one for any of the source classes, see instructions below.
You can use the Create Test intention action by pressing Alt+Enter while standing on the name of your class inside the editor or by using Ctrl+Shift+T keyboard shortcut.
A dialog appears where you select what testing framework to use and press Fix button for the first time to add the required library jars to the module dependencies. You can also select methods to create the test stubs for.
You can find more details in the Testing help section of the on-line documentation.

The String conversion page on the Coder's Toolbox site is handy for encoding more than a small amount of HTML or XML code for inclusion as a value in an XML element.
Heres another approach that I used when doing something similar for a large telescope:
1) Search for the highest pixel. Once you have that, search around that for the best fit for 2x2 (maybe maximizing the 2x2 sum), or do a 2d gaussian fit inside the sub region of say 4x4 centered on the highest pixel.
Then set those 2x2 pixels you have found to zero (or maybe 3x3) around the peak center
go back to 1) and repeat till the highest peak falls below a noise threshold, or you have all the toes you need
@bramp's answer is correct - partially, in that it does not mention that the calculated boundaries will be the minimum rectangle that contains the text fully with implicit start coordinates of 0, 0.
This means, that the height of, for example "Py" will be different from the height of "py" or "hi" or "oi" or "aw" because pixel-wise they require different heights.
This by no means is an equivalent to FontMetrics in classic java.
While width of a text is not much of a pain, height is.
In particular, if you need to vertically center-align the drawn text, try getting the boundaries of the text "a" (without quotes), instead of using the text you intend to draw. Works for me...
Here's what I mean:
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG | Paint.LINEAR_TEXT_FLAG);
paint.setStyle(Paint.Style.FILL);
paint.setColor(color);
paint.setTextAlign(Paint.Align.CENTER);
paint.setTextSize(textSize);
Rect bounds = new Rect();
paint.getTextBounds("a", 0, 1, bounds);
buffer.drawText(this.myText, canvasWidth >> 1, (canvasHeight + bounds.height()) >> 1, paint);
// remember x >> 1 is equivalent to x / 2, but works much much faster
Vertically center aligning the text means vertically center align the bounding rectangle - which is different for different texts (caps, long letters etc). But what we actually want to do is to also align the baselines of rendered texts, such that they did not appear elevated or grooved. So, as long as we know the center of the smallest letter ("a" for example) we then can reuse its alignment for the rest of the texts. This will center align all the texts as well as baseline-align them.
I had the same problem as @User39604, and had to follow VARIOUS advices. Since he doesnt remember the precise path he followed, let me list my path:
check if you have SSL YES using <?php echo phpinfo();?>
if necessary
A. enable ssl on apache sudo a2enmod ssl
B. install openssl sudo apt-get install openssl
C. check if port 443 is open sudo netstat -lp
D. if necessary, change /etc/apache2/ports.conf
, this works
NameVirtualHost *:80
Listen 80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
NameVirtualHost *:443
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>
acquire a key and a certificate by
A. paying a Certificating Authority (Comodo, GoDaddy, Verisign) for a pair
B. generating your own* - see below (testing purposes ONLY)
change your configuration (in ubuntu12 /etc/apache2/httpd.conf
- default is an empty file) to include a proper <VirtualHost>
(replace MYSITE.COM
as well as key and cert path/name to point to your certificate and key):
<VirtualHost _default_:443>
ServerName MYSITE.COM:443
SSLEngine on
SSLCertificateKeyFile /etc/apache2/ssl/MYSITE.COM.key
SSLCertificateFile /etc/apache2/ssl/MYSITE.COM.cert
ServerAdmin MYWEBGUY@localhost
DocumentRoot /var/www

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/accessSSL.log combined
</VirtualHost>
while many other virtualhost configs wil be available in /etc/apache2/sites-enabled/
and in /etc/apache2/sites-available/
it was /etc/apache2/httpd.conf
that was CRUCIAL to solving all problems.

*generating your own certificate (self-signed) will result in a certificate whose authority the user's browser will not recognize. therefore, the browser will scream bloody murder and the user will have to "understand the risks" a dozen times before the browser actually opens up the page. so, it only works for testing purposes. having said that, this is the HOW-TO:
/etc/apache2/
) ssl
(or anything that works for you, the name is not a system requirement)/etc/apache2/ssl
sudo openssl req -new -x509 -nodes -out MYSITE.COM.crt -keyout MYSITE.COM.key
MYSITE.COM.crt
and MYSITE.COM.key
in your <VirtualHost>
tag name format is NOT under a strict system requirement, must be the same as the file :)
- names like 212-MYSITE.COM.crt
, june2014-Godaddy-MYSITE.COM.crt
should work.
From the Google Font Directory examples:
@font-face {
font-family: 'Tangerine';
font-style: normal;
font-weight: normal;
src: local('Tangerine'), url('http://example.com/tangerine.ttf') format('truetype');
}
body {
font-family: 'Tangerine', serif;
font-size: 48px;
}
This works cross browser with .ttf, I believe it may work with .otf. (Wikipedia says .otf is mostly backwards compatible with .ttf) If not, you can convert the .otf to .ttf
Here are some good sites:
Good primer:
Other Info:
"Java SE8 for Programmers" claims that the Java will cope with either. (pp. 480, last paragraph). The example claims that:
c:\Program Files\Java\jdk1.6.0_11\demo/jfc
will parse just fine. Take note of the last (Unix-style) separator.
It's tacky, and probably error-prone, but it is what they (Deitel and Deitel) claim.
I think the confusion for people, rather than Java, is reason enough not to use this (mis?)feature.
Simple solution to drop all the table at once from terminal.
This involved few steps inside your mysql shell (not a one step solution though), this worked me and saved my day.
Worked for Server version: 5.6.38 MySQL Community Server (GPL)
Steps I followed:
1. generate drop query using concat and group_concat.
2. use database
3. turn off / disable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 0;),
4. copy the query generated from step 1
5. re enable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 1;)
6. run show table
MySQL shell
$ mysql -u root -p
Enter password: ****** (your mysql root password)

There is something called Rule of Thumb. It says that the number of clusters can be calculated by
k = (n/2)^0.5
where n is the total number of elements from your sample. You can check the veracity of this information on the following paper:
http://www.ijarcsms.com/docs/paper/volume1/issue6/V1I6-0015.pdf
There is also another method called G-means, where your distribution follows a Gaussian Distribution or Normal Distribution. It consists of increasing k until all your k groups follow a Gaussian Distribution. It requires a lot of statistics but can be done. Here is the source:
http://papers.nips.cc/paper/2526-learning-the-k-in-k-means.pdf
I hope this helps!
The main (very interesting) difference for me is that:
"string" & Null
-> "string"
while
"string" + Null
-> Null
But that's probably more useful in database apps like Access.
One I can answer confidently!
DateTime expiryDate = DateTime.Now.AddDays(30);
Or possibly - if you just want the date without a time attached which might be more appropriate:
DateTime expiryDate = DateTime.Today.AddDays(30);
When I had this problem, I had included the mail-api.jar
in my maven pom file. That's the API specification only. The fix is to replace this:
<!-- DO NOT USE - it's just the API, not an implementation -->
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>
with the reference implementation of that api:
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
I know it has sun in the package name, but that's the latest version. I learned this from https://stackoverflow.com/a/28935760/1128668
My experience with larger files sizes has been that java.nio
is faster than java.io
. Solidly faster. Like in the >250% range. That said, I am eliminating obvious bottlenecks, which I suggest your micro-benchmark might suffer from. Potential areas for investigating:
The buffer size. The algorithm you basically have is
My own experience has been that this buffer size is ripe for tuning. I've settled on 4KB for one part of my application, 256KB for another. I suspect your code is suffering with such a large buffer. Run some benchmarks with buffers of 1KB, 2KB, 4KB, 8KB, 16KB, 32KB and 64KB to prove it to yourself.
Don't perform java benchmarks that read and write to the same disk.
If you do, then you are really benchmarking the disk, and not Java. I would also suggest that if your CPU is not busy, then you are probably experiencing some other bottleneck.
Don't use a buffer if you don't need to.
Why copy to memory if your target is another disk or a NIC? With larger files, the latency incured is non-trivial.
Like other have said, use FileChannel.transferTo()
or FileChannel.transferFrom()
. The key advantage here is that the JVM uses the OS's access to DMA (Direct Memory Access), if present. (This is implementation dependent, but modern Sun and IBM versions on general purpose CPUs are good to go.) What happens is the data goes straight to/from disc, to the bus, and then to the destination... bypassing any circuit through RAM or the CPU.
The web app I spent my days and night working on is very IO heavy. I've done micro benchmarks and real-world benchmarks too. And the results are up on my blog, have a look-see:
Use production data and environments
Micro-benchmarks are prone to distortion. If you can, make the effort to gather data from exactly what you plan to do, with the load you expect, on the hardware you expect.
My benchmarks are solid and reliable because they took place on a production system, a beefy system, a system under load, gathered in logs. Not my notebook's 7200 RPM 2.5" SATA drive while I watched intensely as the JVM work my hard disc.
What are you running on? It matters.
Also ensure that "client tools" are selected in the install options. However if SQL Managment Studio 2008 exists then it is likely that you installed the express edition.
This works perfectly, and on iPad too.

Who do you trust?
I've always considered this area too critical to trust a third party to manage the runtime security of your application. Once that component is cracked for one application, it's cracked for all applications. It happened to Discreet in five minutes once they went with a third-party license solution for 3ds Max years ago... Good times!
Seriously, consider rolling your own for having complete control over your algorithm. If you do, consider using components in your key along the lines of:
Then checksum the hell out of them and add whatever (reversable) encryption you want to it to make it harder to crack.
To make a trial license key, simply have set values for the above values that translate as "trial mode".
And since this is now probably the most important code in your application/company, on top of/instead of obfuscation consider putting the decrypt routines in a native DLL file and simply P/Invoke to it.
Several companies I've worked for have adopted generalised approaches for this with great success. Or maybe the products weren't worth cracking ;)
If you want to make sure the operators of your custom type are called you can do so via reflection. Just get the type using your generic parameter and retrieve the MethodInfo for the desired operator (e.g. op_Equality, op_Inequality, op_LessThan...).
var methodInfo = typeof (T).GetMethod("op_Equality",
BindingFlags.Static | BindingFlags.Public);
Then execute the operator using the MethodInfo's Invoke method and pass in the objects as the parameters.
var result = (bool) methodInfo.Invoke(null, new object[] { object1, object2});
This will invoke your overloaded operator and not the one defined by the constraints applied on the generic parameter. Might not be practical, but could come in handy for unit testing your operators when using a generic base class that contains a couple of tests.

/// <summary>

/// <param name="value"></param>

public static T Get<T>(object value)
{
return value == DBNull.Value ? default(T) : (T)value;
}
}
use like this
DBH.Get<String>(itemRow["MyField"])
The Java heap size limits for Windows are:
This doesn't help you getting a bigger Java heap, but now you know you can't go beyond these values.
Since this is like a "wikipage of code" I want to add some code from the QNX Knowledge base (note: this is not my work, but I checked it and it works fine on my system):

Since this question now features prominently when searching for YAML and JSON, it's worth noting one rarely-cited difference between the two: license. JSON purports to have a license which JSON users must adhere to (including the legally-ambiguous "shall be used for Good, not Evil"). YAML carries no such license claim, and that might be an important difference (to your lawyer, if not to you).
Just wondering why you are using 2 directives?
It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.
Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).
It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.
Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.
In my case got a working solution through Cross-document Messaging (XDM) and Executing Chrome extension onclick instead of page load.

At last i did it Thanks alot friends, and a special thanks to Mr https://stackoverflow.com/users/87015/salman-a because of his code i was able to solve it properly. finally my code is looking like this as i am using groovy grails i hope this will help somebody there.. Thanks alot
html code looks like this in my gsp page
<input id="populate-dropdown" name="nameofClient" type="text">
<input id="wilhaveid" name="idofclient" type="text">
script Function is like this in my gsp page
<script>
$( "#populate-dropdown").on('input', function() {
$.ajax({
url:'autoCOmp',
data: {inputField: $("#populate-dropdown").val()},
success: function(resp){
$('#populate-dropdown').autocomplete({
source:resp,
select: function (event, ui) {
$("#populate-dropdown").val(ui.item.label);
$("#wilhaveid").val(ui.item.value);
return false;
}
})
}
});
});
</script>
And my controller code is like this
def autoCOmp(){
println(params)
def c = Client.createCriteria()
def results = c.list {
like("nameOfClient", params.inputField+"%")
}
def itemList = []
results.each{
itemList << [value:it.id,label:it.nameOfClient]
}
println(itemList)
render itemList as JSON
}
One more thing i have not set id field hidden because at first i was checking that i am getting the exact id , you can keep it hidden just put type=hidden instead of text for second input item in html
Thanks !
If I want the sort to be applied to only one of the UNION if use Union all:
Select id,name,age
From Student
Where age < 15
Union all
Select id,name,age
From
(
Select id,name,age
From Student
Where Name like "%a%"
Order by name
)
Indeed, there is type conversion to int. Also you can force type to char by using %hhx specifier.
printf("%hhX", a);
In most cases you will want to set the minimum length as well to fill the second character with zeroes:
printf("%02hhX", a);
ISO/IEC 9899:201x says:
7 The length modifiers and their meanings are: hh Specifies that a following d, i, o, u, x, or X conversion specifier applies to a signed char or unsigned char argument (the argument will have been promoted according to the integer promotions, but its value shall be converted to signed char or unsigned char before printing); or that a following
For splitting an InputStream
in two, while avoiding to load all data in memory, and then process them independently:
OutputStream
, precisely: PipedOutputStream
PipedInputStream
are the returned InputStream
.OutputStream
. So, everything read it from the sourcing InputStream
, would be written in both OutputStream
. There is not need to implement that, because it is done already in TeeInputStream
(commons.io).Within a separated thread read the whole sourcing inputStream, and implicitly the input data is transferred to the target inputStreams.
public static final List<InputStream> splitInputStream(InputStream input)
throws IOException
{
Objects.requireNonNull(input);
PipedOutputStream pipedOut01 = new PipedOutputStream();
PipedOutputStream pipedOut02 = new PipedOutputStream();
List<InputStream> inputStreamList = new ArrayList<>();
inputStreamList.add(new PipedInputStream(pipedOut01));
inputStreamList.add(new PipedInputStream(pipedOut02));
TeeOutputStream tout = new TeeOutputStream(pipedOut01, pipedOut02);
TeeInputStream tin = new TeeInputStream(input, tout, true);
Executors.newSingleThreadExecutor().submit(tin::readAllBytes);
return Collections.unmodifiableList(inputStreamList);
}
Be aware to close the inputStreams after being consumed, and close the thread that runs: TeeInputStream.readAllBytes()
In case, you need to split it into multiple InputStream
, instead of just two. Replace in the previous fragment of code the class TeeOutputStream
for your own implementation, which would encapsulate a List<OutputStream>
and override the OutputStream
interface:
public final class TeeListOutputStream extends OutputStream {
private final List<? extends OutputStream> branchList;
public TeeListOutputStream(final List<? extends OutputStream> branchList) {
Objects.requireNonNull(branchList);
this.branchList = branchList;
}
@Override
public synchronized void write(final int b) throws IOException {
for (OutputStream branch : branchList) {
branch.write(b);
}
}
@Override
public void flush() throws IOException {
for (OutputStream branch : branchList) {
branch.flush();
}
}
@Override
public void close() throws IOException {
for (OutputStream branch : branchList) {
branch.close();
}
}
}
if any(t < 0 for t in x):
# do something
Also, if you're going to use "True in ...", make it a generator expression so it doesn't take O(n) memory:
if True in (t < 0 for t in x):
Aside from @see
, a more general way of refering to another class and possibly method of that class is {@link somepackage.SomeClass#someMethod(paramTypes)}
. This has the benefit of being usable in the middle of a javadoc description.
From the javadoc documentation (description of the @link tag):
This tag is very simliar to @see – both require the same references and accept exactly the same syntax for package.class#member and label. The main difference is that {@link} generates an in-line link rather than placing the link in the "See Also" section. Also, the {@link} tag begins and ends with curly braces to separate it from the rest of the in-line text.
From the Package Explorer in Eclipse, you can right click the project, choose Build Path, Configure Build Path to get the build path dialog. From there you can remove the JRE reference for the 1.5 JRE and 'Add Library' to add a reference to your installed JRE.

For me it only worked when I set the permission on the phone itself (settings -> app permissions -> location always on).
I found it at

static class Extensions
{
public static T[] Concat<T>(this T[] array1, params T[] array2) => ConcatArray(array1, array2);
public static T[] ConcatArray<T>(params T[][] arrays)
{
int l, i;
for (l = i = 0; i < arrays.Length; l += arrays[i].Length, i++);
var a = new T[l];
for (l = i = 0; i < arrays.Length; l += arrays[i].Length, i++)
arrays[i].CopyTo(a, l);
return a;
}
}
I think the above solution is more general & lighter than the others I saw here. It is more general because it doesn't limit concatenation for only two arrays and is lighter because it doesn't use LINQ nor List.
Note the solution is concise and the added generality doesn't add significant runtime overhead.
I answer this coming from a component-based architecture, where an organisation may be running many components that may rely on each other. During a propagating failure, logging levels should help to identify both which components are affected and which are a root cause.
ERROR - This component has had a failure and the cause is believed to be internal (any internal, unhandled exception, failure of encapsulated dependency... e.g. database, REST example would be it has received a 4xx error from a dependency). Get me (maintainer of this component) out of bed.
WARN - This component has had a failure believed to be caused by a dependent component (REST example would be a 5xx status from a dependency). Get the maintainers of THAT component out of bed.
INFO - Anything else that we want to get to an operator. If you decide to log happy paths then I recommend limiting to 1 log message per significant operation (e.g. per incoming http request).
For all log messages be sure to log useful context (and prioritise on making messages human readable/useful rather than having reams of "error codes")
A nice way to visualise the above logging levels is to imagine a set of monitoring screens for each component. When all running well they are green, if a component logs a WARNING then it will go orange (amber) if anything logs an ERROR then it will go red.
In the event of an incident you should have one (root cause) component go red and all the affected components should go orange/amber.
I agree with pm100 (and should have explicitly said this in my earlier post).
You should never implement IDisposable in a class unless you need it. To be very specific, there are about 5 times when you would ever need/should implement IDisposable:
Your class explicitly contains (i.e. not via inheritance) any managed resources which implement IDisposable and should be cleaned up once your class is no longer used. For example, if your class contains an instance of a Stream, DbCommand, DataTable, etc.
Your class explicitly contains any managed resources which implement a Close() method - e.g. IDataReader, IDbConnection, etc. Note that some of these classes do implement IDisposable by having Dispose() as well as a Close() method.
Your class explicitly contains an unmanaged resource - e.g. a COM object, pointers (yes, you can use pointers in managed C# but they must be declared in 'unsafe' blocks, etc. In the case of unmanaged resources, you should also make sure to call System.Runtime.InteropServices.Marshal.ReleaseComObject() on the RCW. Even though the RCW is, in theory, a managed wrapper, there is still reference counting going on under the covers.
If your class subscribes to events using strong references. You need to unregister/detach yourself from the events. Always to make sure these are not null first before trying to unregister/detach them!.
Your class contains any combination of the above...
A recommended alternative to working with COM objects and having to use Marshal.ReleaseComObject() is to use the System.Runtime.InteropServices.SafeHandle class.
The BCL (Base Class Library Team) has a good blog post about it here http://blogs.msdn.com/bclteam/archive/2005/03/16/396900.aspx
One very important note to make is that if you are working with WCF and cleaning up resources, you should ALMOST ALWAYS avoid the 'using' block. There are plenty of blog posts out there and some on MSDN about why this is a bad idea. I have also posted about it here - Don't use 'using()' with a WCF proxy
The other answers may have been useful years ago, but they are now out of date.
Given that a project has a tsconfig file, run this command...
tsc --watch
... to watch for changed files and compile as needed. The documentation explains:
Run the compiler in watch mode. Watch input files and trigger recompilation on changes. The implementation of watching files and directories can be configured using environment variable. See configuring watch for more details.
To answer the original question, recursive directory watching is possible even on platforms that don't have native support, as explained by the Configuring Watch docs:
The watching of directory on platforms that don’t support recursive directory watching natively in node, is supported through recursively creating directory watcher for the child directories using different options selected by TSC_WATCHDIRECTORY
In my case, the issue was caused by a connection problem to the SQL database. I just disconnected and then reconnected the SQL datasource from the design view. I am back up and running. Hope this works for everyone.
put .gitignore in your main catalog
git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push
You can do that with a grid:
article {
display: grid;
}
.one {
grid-area: 1 / 1 / 2 / 2;
}
.two {
grid-area: 1 / 1 / 2 / 2;
}
Another interesting way to do it which would also allow more than just the last number to be taken would be:
int number = 124454;
int overflow = (int)Math.floor(number/(1*10^n))*10^n;
int firstDigits = number - overflow;
//Where n is the number of numbers you wish to conserve</code>
In the above example if n was 1 then the program would return: 4
If n was 3 then the program would return 454

You should use append to add to the list. But also here are few code tips:
I would use dict.setdefault
or defaultdict
to avoid having to specify the empty list in the dictionary definition.
If you use prev
to to filter out duplicated values you can simplfy the code using groupby
from itertools
Your code with the amendments looks as follows:
import itertools
def make_drug_dictionary(data):
drug_dictionary = {}
for key, row in itertools.groupby(data, lambda x: x[11]):
drug_dictionary.setdefault(key,[]).append(row[?])
return drug_dictionary
If you don't know how groupby works just check this example:
>>> list(key for key, val in itertools.groupby('aaabbccddeefaa'))
['a', 'b', 'c', 'd', 'e', 'f', 'a']
Note: you should use the accepted answer if possible. It's better than mine.
It's quite easy with the GD library.
It's built in usually, you probably have it (use phpinfo()
to check)
$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagejpeg($image, "folder/file.jpg");
The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).
$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");
This only works if allow_url_fopen
is true
(it is by default)
Besides using Android Studio, you can also take a screenshot with adb which is faster.
adb shell screencap -p /sdcard/screen.png
adb pull /sdcard/screen.png
adb shell rm /sdcard/screen.png
Shorter one line alternative in Unix/OSX
adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png

I've used node-cron and agenda.
node-cron is a very simple library, which provide very basic and easy to understand api like crontab. It doesn't need any config and just works.
var cronJob = require('cron').CronJob;
var myJob = new cronJob('00 30 11 * * 1-5', function(){...});
myJob.start();
agenda is very powerful and fit for much more complex services. Think about ifttt, you have to run millions of tasks. agenda would be the best choice.
Note: You need Mongodb to use Agenda
var Agenda = require("Agenda");
var agenda = new Agenda({db: { address: 'localhost:27017/agenda-example'}});
agenda.every('*/3 * * * *', 'delete old users');
agenda.start();
You can clean cache in React Native >= 0.50 and npm > 5 :
watchman watch-del-all &&
rm -rf $TMPDIR/react-native-packager-cache-* &&
rm -rf $TMPDIR/metro-bundler-cache-* &&
rm -rf node_modules/
&& npm cache clean --force &&
npm install &&
npm start -- --reset-cache
Apart from cleaning npm cache you might need to reset simulator or clean build etc.
Only nested classes can be static. By doing so you can use the nested class without having an instance of the outer class.
class OuterClass {
public static class StaticNestedClass {
}
public class InnerClass {
}
public InnerClass getAnInnerClass() {
return new InnerClass();
}
//This method doesn't work
public static InnerClass getAnInnerClassStatically() {
return new InnerClass();
}
}
class OtherClass {
//Use of a static nested class:
private OuterClass.StaticNestedClass staticNestedClass = new OuterClass.StaticNestedClass();
//Doesn't work
private OuterClass.InnerClass innerClass = new OuterClass.InnerClass();
//Use of an inner class:
private OuterClass outerclass= new OuterClass();
private OuterClass.InnerClass innerClass2 = outerclass.getAnInnerClass();
private OuterClass.InnerClass innerClass3 = outerclass.new InnerClass();
}

Another solution is to run it like this for IE9 and later
iexplore.exe" -noframemerging http://google.com
iexplore.exe" -noframemerging http://gmail.com
-noframemerging means run IE independently. For example it you want to run 2 browser and login as different username it will not work if you just run 2 IE. but with -noframemerging it will work. -noframemerging works for IE9 and later, for early versions like IE8 it is -nomerge
usually I create 1 but file like this run_ie.bat
"c:\Program Files (x86)\Internet Explorer\iexplore.exe" -noframemerging %1

Despite the question is tagged as c

template functions, current GCC implementation uses bitshifting and works with any integral unsigned type.
For recovering a deleted branch, First go through the reflog history,
git reflog -n 60
Where n refers to the last n commits. Then find the proper head and create a branch with that head.
git branch testbranch HEAD@{30}
First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).
Neither is supported by Windows command-line ftp.exe
. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.
Using WinSCP, your batch file would look like (for SFTP):
echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat
And the batch file:
winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%
Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP%
syntax), the batch file simplifies to:
winscp.com /log=ftpcmd.log /command ^
"open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
"put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
"exit"
For the purpose of -hostkey
switch, see verifying the host key in script.
Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:
All you need to tweak is the source file name (use the %TIMESTAMP%
syntax as shown previously) and the path to the log file.
For FTPS, replace the sftp://
in the open
command with ftpes://
(explicit TLS/SSL) or ftps://
(implicit TLS/SSL). Remove the -hostkey
switch.
winscp.com /log=ftpcmd.log /command ^
"open ftps://ftp_user:[email protected] -explicit" ^
"put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
"exit"
You may need to add the -certificate
switch, if your server's certificate is not issued by a trusted authority.
Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.
See a complete conversion guide from ftp.exe
to WinSCP.
You should also read the Guide to automating file transfers to FTP server or SFTP server.
Note to using %TIMESTAMP#yyyymmdd%
instead of %date%
: A format of %date%
variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date%
resolves to ct 06. 11. 2014
, what might be problematic when used as a part of a file name.
For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd%
resolves to 20170515
on any locale.

You can use the CSS3 Linear Gradient property along with your background-image like this:
#landing-wrapper {
display:table;
width:100%;
background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
background-position:center top;
height:350px;
}

#landing-wrapper {_x000D_
display: table;_x000D_
width: 100%;_x000D_
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
background-position: center top;_x000D_

All these answers address the title question, but I wanted to propose some solutions for the problems presented in the body of the OP's question.
A quick way to calculate the size of the text inside the UITextView
is to use the NSLayoutManager
:
UITextView *textView;
CGSize textSize = [textView usedRectForTextContainer:textView.textContainer].size;
This gives the total scrollable content, which may be bigger than the UITextView
's frame. I found this to be much more accurate than textView.contentSize
since it actually calculates how much space the text takes up. For example, given an empty UITextView
:
textView.frame.size = (width=246, height=50)
textSize = (width=10, height=16.701999999999998)
textView.contentSize = (width=246, height=33)
textView.textContainerInset = (top=8, left=0, bottom=8, right=0)
UIFont
has a property that quickly allows you to get the line height for the given font. So you can quickly find the line height of the text in your UITextView
with:
UITextView *textView;
CGFloat lineHeight = textView.font.lineHeight;
Determining the amount of text that is actually visible is important for handling a "paging" effect. UITextView
has a property called textContainerInset
which actually is a margin between the actual UITextView.frame
and the text itself. To calculate the real height of the visible frame you can perform the following calculations:
UITextView *textView;
CGFloat textViewHeight = textView.frame.size.height;
UIEdgeInsets textInsets = textView.textContainerInset;
CGFloat textHeight = textViewHeight - textInsets.top - textInsets.bottom;
Lastly, now that you have the visible text size and the content, you can quickly determine what your offsets should be by subtracting the textHeight
from the textSize
:
// where n is the page number you want
CGFloat pageOffsetY = textSize - textHeight * (n - 1);
textView.contentOffset = CGPointMake(textView.contentOffset.x, pageOffsetY);
// examples
CGFloat page1Offset = 0;
CGFloat page2Offset = textSize - textHeight
CGFloat page3Offset = textSize - textHeight * 2
Using all of these methods, I didn't touch my insets and I was able to go to the caret or wherever in the text that I want.

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.
So register the ChildComponent in Shared Module manually.

YearMonth
The YearMonth
class makes this easy. The atEndOfMonth
method returns a LocalDate
. Leap year in February is accounted for.
First define a formatting pattern to match your string input.
DateTimeFormatter f = DateTimeFormatter.ofPattern( "M/d/uuuu" ) ;
Use that formatter to get a LocalDate
from the string input.
String s = "1/13/2012" ;
LocalDate ld = LocalDate.parse( "1/13/2012" , f ) ;
Then extract a YearMonth
object.
YearMonth ym = YearMonth.from( ld ) ;
Ask that YearMonth
to determine the last day of its month in that year, accounting for Leap Year in February.
LocalDate endOfMonth = ym.atEndOfMonth() ;
Generate text representing that date, in standard ISO 8601 format.
String output = endOfMonth.toString() ;
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
Remove "strictNullChecks": true from "compilerOptions" or set it to false in the tsconfig.json file of your Ng app. These errors will go away like anything and your app would compile successfully.
Disclaimer: This is just a workaround. This error appears only when the null checks are not handled properly which in any case is not a good way to get things done.
The problem was the notify filters. The program was trying to open a file that was still copying. I removed all of the notify filters except for LastWrite.

watcher.NotifyFilter = NotifyFilters.LastWrite;
watcher.Filter = "*.*";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.EnableRaisingEvents = true;

The simplest solutions seem to overlook that UTC time will be used, including highly up-voted ones. Below is a streamlined, ES6, non-jQuery version of a couple of existing answers:

const day = now.getDate().toString().padStart(2, '0');
return `${now.getFullYear()}-${month}-${day}`;
})();
console.log(today); // as of posting this answer: 2019-01-24

Short walk through:
Add a new item to the list:
SPListItem newItem = list.AddItem();
To bind you new item to a content type you have to set the content type id for the new item:
newItem["ContentTypeId"] = <Id of the content type>;
Set the fields specified within your content type.
Commit your changes:
newItem.Update();
I fixed it with Datejs
This is alerting the first day:
var fd = Date.today().clearTime().moveToFirstDayOfMonth();
var firstday = fd.toString("MM/dd/yyyy");
alert(firstday);
This is for the last day:
var ld = Date.today().clearTime().moveToLastDayOfMonth();
var lastday = ld.toString("MM/dd/yyyy");
alert(lastday);

By default, when you are inside a function, you do not have access to the outer variables.
If you want your function to have access to an outer variable, you have to declare it as global
, inside the function :
function someFuntion(){
global $myArr;
$myVal = //some processing here to determine value of $myVal
$myArr[] = $myVal;
}
For more informations, see Variable scope.
But note that using global variables is not a good practice : with this, your function is not independant anymore.
A better idea would be to make your function return the result :
function someFuntion(){
$myArr = array(); // At first, you have an empty array
$myVal = //some processing here to determine value of $myVal
$myArr[] = $myVal; // Put that $myVal into the array
return $myArr;
}
And call the function like this :
$result = someFunction();
Your function could also take parameters, and even work on a parameter passed by reference :
function someFuntion(array & $myArr){
$myVal = //some processing here to determine value of $myVal
$myArr[] = $myVal; // Put that $myVal into the array
}
Then, call the function like this :
$myArr = array( ... );
someFunction($myArr); // The function will receive $myArr, and modify it
With this :
For more informations about that, you should read the Functions section of the PHP manual, and,, especially, the following sub-sections :

Before HTML5, we have an easy but workable way: Firstly set an maxlength attribute in the textarea element:
<textarea maxlength='250' name=''></textarea>
Then use JavaScript to limit user input:
$(function() {
$("textarea[maxlength]").bind('input propertychange', function() {
var maxLength = $(this).attr('maxlength');
if ($(this).val().length > maxLength) {
$(this).val($(this).val().substring(0, maxLength));
}
})
});
Make sure the bind both "input" and "propertychange" events to make it work on various browsers such as Firefox/Safari and IE.

I had similar issues with the threads being started in Spring bean. These threads were not closing properly after i called executor.shutdownNow() in @PreDestroy method. So the solution for me was to let the thread finsih with IO already started and start no more IO, once @PreDestroy was called. And here is the @PreDestroy method. For my application the wait for 1 second was acceptable.
@PreDestroy
public void beandestroy() {
this.stopThread = true;
if(executorService != null){
try {
// wait 1 second for closing all threads
executorService.awaitTermination(1, TimeUnit.SECONDS);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}
}
Here I have explained all the issues faced while trying to close threads.http://programtalk.com/java/executorservice-not-shutting-down/
You can use netcat command as well
[location of netcat]/netcat -zv [ip] [port]
or
nc -zv [ip] [port]
-z – sets nc to simply scan for listening daemons, without actually sending any data to them.
-v – enables verbose mode.
Try this:
str.replace("\"", "\\\""); // (Escape backslashes and embedded double-quotes)
Or, use single-quotes to quote your search and replace strings:
str.replace('"', '\\"'); // (Still need to escape the backslash)
As pointed out by helmus, if the first parameter passed to .replace()
is a string it will only replace the first occurrence. To replace globally, you have to pass a regex with the g
(global) flag:
str.replace(/"/g, "\\\"");
// or
str.replace(/"/g, '\\"');
But why are you even doing this in JavaScript? It's OK to use these escape characters if you have a string literal like:
var str = "Dude, he totally said that \"You Rock!\"";
But this is necessary only in a string literal. That is, if your JavaScript variable is set to a value that a user typed in a form field you don't need to this escaping.
Regarding your question about storing such a string in an SQL database, again you only need to escape the characters if you're embedding a string literal in your SQL statement - and remember that the escape characters that apply in SQL aren't (usually) the same as for JavaScript. You'd do any SQL-related escaping server-side.
You can see a detailed description here.

First think of a solution without code. The idea is to print an odd number of *, increasing by line. Then center the * by using spaces. Knowing the max number of * in the last line, will give you the initial number of spaces to center the first *. Now write it in code.

I had given an answer in Super User site for the thread "Open a network drive with different user" (https://superuser.com/questions/577113/open-a-network-drive-with-different-user/1524707#1524707)
I want to use a router's USB drive as a network storage for different users, as this thread I met the error message
"Multiple Connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."
Beside the method using "NET USE" command, I found another way from the webpage
It is better to solve the Windows connection limitation by editing the hosts file which is under the directory "C:\Windows\System32\Drivers\etc".
For example, my router IP address is 192.168.1.1 and its USB drive has three share folders as \user1, \user2 and \user3 which separated for three users, then we can add the following three lines in hosts file,
192.168.1.1 server1
192.168.1.1 server2
192.168.1.1 server3
in this example we map the server1 to user #1, server2 to user #2 and server3 to user #3.
After reboot the PC, we can connect the folder \user1 for user #1, \user2 for user #2 and \user3 for user #3 simultaneously in Windows File Explorer, that is
if we type the router name as \\server1 in folder indication field of Explorer, it will show all shared folders of router's USB drive in Explorer right pane and sever1 under "Network" item in left pane of Explorer, then the user #1 may access the share folder \user1.
At this time if we type \\server2 or \\server3 in the directory indication field of Explorer, then we may connect the router's USB drive as server2 or server3 and access the share folder \user2 or \user3 for user #2 or user #3 and keep the "server1" connection simultaneously.
Using this method we may also use the "NET USE" command to do these actions.
In addition to running it with mvn exec:java
, you can also run it with mvn exec:exec
mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath your.package.MainClass"
You need to use AND statement in your formula
=IF(AND(IF(NOT(ISBLANK(Q2));TRUE;FALSE);Q2<=R2);"1";"0")
And if both conditions are met, return 1.
You could also add more conditions in your AND statement.
You don't really want to be reallocing memory every time you remove something. If you know the rough size of your deck then choose an appropriate size for your array and keep a pointer to the current end of the list. This is a stack.
If you don't know the size of your deck, and think it could get really big as well as keeps changing size, then you will have to do something a little more complex and implement a linked-list.
In C, you have two simple ways to declare an array.
On the stack, as a static array
int myArray[16]; // Static array of 16 integers
On the heap, as a dynamically allocated array
// Dynamically allocated array of 16 integers
int* myArray = calloc(16, sizeof(int));
Standard C does not allow arrays of either of these types to be resized. You can either create a new array of a specific size, then copy the contents of the old array to the new one, or you can follow one of the suggestions above for a different abstract data type (ie: linked list, stack, queue, etc).
Use regular expression to match your requirement.
String num,num1,num2;
String str = "123-456-789";
String regex ="(\\d+)";
Matcher matcher = Pattern.compile( regex ).matcher( str);
while (matcher.find( ))
{
num = matcher.group();
System.out.print(num);
}
All solutions already proposed have severe problems. Some solutions fail to work on large arrays, some provide wrong output, some throw an error on btoa call if an intermediate string contains multibyte characters, some consume more memory than needed.
So I implemented a direct conversion function which just works regardless of the input. It converts about 5 million bytes per second on my machine.

As a general point when using a search engine to search for SQL codes make sure you put the sqlcode e.g. -302 in quote marks - like "-302" otherwise the search engine will exclude all search results including the text 302, since the - sign is used to exclude results.
It only appeared in my Chrome browser a few days ago too. I checked a few websites I developed in the past that haven't been changed and they also show the same error. So I'd suggest it's not down to your coding, rather a bug in the latest Chrome release.
I normally use Emacs (it has everything you need included).
Of course, there are other options available:
Cheers.
I've used a DOS command line to do this. Two lines, actually. The first one to make the "current directory" the folder where the file is - or the root folder of a group of folders where the file can be. The second line does the search.
CD C:\TheFolder
C:\TheFolder>FINDSTR /L /S /I /N /C:"TheString" *.PRG
You can find details about the parameters at this link.
Hope it helps!
your code compiles here fine (even with that line uncommented. had to change it to

If you really want to process your file line by line, a solution might be to use fgetl
:
fopen
fgetl
sscanf
on the character array you just readUnlike the previous answer, this is not very much in the style of Matlab but it might be more efficient on very large files.
Hope this will help.
Components control views (html). They also communicate with other components and services to bring functionality to your app.
Modules consist of one or more components. They do not control any html. Your modules declare which components can be used by components belonging to other modules, which classes will be injected by the dependency injector and which component gets bootstrapped. Modules allow you to manage your components to bring modularity to your app.
please note, if you use $filter like this:
$scope.failedSubjects = $filter('filter')($scope.results.subjects, {'grade':'C'});
and you happened to have another grade for, Oh I don't know, CC or AC or C+ or CCC it pulls them in to. you need to append a requirement for an exact match:
$scope.failedSubjects = $filter('filter')($scope.results.subjects, {'grade':'C'}, true);
This really killed me when I was pulling in some commission details like this:
var obj = this.$filter('filter')(this.CommissionTypes, { commission_type_id: 6}))[0];
only get called in for a bug because it was pulling in the commission ID 56 rather than 6.
Adding the true forces an exact match.
var obj = this.$filter('filter')(this.CommissionTypes, { commission_type_id: 6}, true))[0];
Yet still, I prefer this (I use typescript, hence the "Let" and =>):
let obj = this.$filter('filter')(this.CommissionTypes, (item) =>{
return item.commission_type_id === 6;
})[0];
I do that because, at some point down the road, I might want to get some more info from that filtered data, etc... having the function right in there kind of leaves the hood open.
AskTom is probably the single most helpful resource on best practices on Oracle DBs. (I usually just type "asktom" as the first word of a google query on a particular topic)
I don't think it's really appropriate to speak of design patterns with relational databases. Relational databases are already the application of a "design pattern" to a problem (the problem being "how to represent, store and work with data while maintaining its integrity", and the design being the relational model). Other approches (generally considered obsolete) are the Navigational and Hierarchical models (and I'm nure many others exist).
Having said that, you might consider "Data Warehousing" as a somewhat separate "pattern" or approach in database design. In particular, you might be interested in reading about the Star schema.
Maybe this old topic but i found this library is very helpful and easy to use

This is the unsorted list and we want is 1234567
list = [3,1,2,5,4,7,6]
def sort(list):
for i in range(len(list)-1):
if list[i] > list[i+1]:
a = list[i]
list[i] = list[i+1]
list[i+1] = a
print(list)
sort(list)
simplest in simplest method to sort a array. Im using currently bubble sorting that is: it checks first 2 location and moves the smallest number to left so on. "-n"in loop is to avoid the indentation error you will understand it by doing it so.
In case you do not need indentation that much but a few line breaks, it could be sufficient to simply regex...
String leastPrettifiedXml = uglyXml.replaceAll("><", ">\n<");
The code is nice, not the result because of missing indentation.
(For solutions with indentation, see other answers.)
Just wanted to show that there is no performance difference between the 2 main ways of doing it:
df = pd.DataFrame(np.random.randint(0,10,size=(100, 4)), columns=list('ABCD'))
def loc():
df1.loc[df1["A"] == 2] = 5
%timeit loc
19.9 ns ± 0.0873 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
def replace():
df2['A'].replace(
to_replace=2,
value=5,
inplace=True
)
%timeit replace
19.6 ns ± 0.509 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
As for "pure python" solutions: the package index lists:
You can use RegEdit to export the following two keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
HKEY_CURRENT_USER\Environment
The first set are system/global environment variables; the second set are user-level variables. Edit as needed and then import the .reg files on the new machine.
An alternative to overriding VerifyRenderingInServerForm is to remove the grid from the controls collection while you do the render, and then add it back when you are finished before the page loads. This is helpful if you want to have some generic helper method to get grid html because you don't have to remember to add the override.
Control parent = grid.Parent;
int GridIndex = 0;
if (parent != null)
{
GridIndex = parent.Controls.IndexOf(grid);
parent.Controls.Remove(grid);
}
grid.RenderControl(hw);
if (parent != null)
{
parent.Controls.AddAt(GridIndex, grid);
}
Another alternative to avoid the override is to do this:
grid.RenderBeginTag(hw);
grid.HeaderRow.RenderControl(hw);
foreach (GridViewRow row in grid.Rows)
{
row.RenderControl(hw);
}
grid.FooterRow.RenderControl(hw);
grid.RenderEndTag(hw);
Dereferencing just means reading the memory value at a given address. So when you have a pointer to something, to dereference the pointer means to read or write the data that the pointer points to.
In C, the unary *
operator is the dereferencing operator. If x
is a pointer, then *x
is what x
points to. The unary &
operator is the address-of operator. If x
is anything, then &x
is the address at which x
is stored in memory. The *
and &
operators are inverses of each other: if x
is any data, and y
is any pointer, then these equations are always true:
*(&x) == x
&(*y) == y
A null pointer is a pointer that does not point to any valid data (but it is not the only such pointer). The C standard says that it is undefined behavior to dereference a null pointer. This means that absolutely anything could happen: the program could crash, it could continue working silently, or it could erase your hard drive (although that's rather unlikely).
In most implementations, you will get a "segmentation fault" or "access violation" if you try to do so, which will almost always result in your program being terminated by the operating system. Here's one way a null pointer could be dereferenced:
int *x = NULL; // x is a null pointer
int y = *x; // CRASH: dereference x, trying to read it
*x = 0; // CRASH: dereference x, trying to write it
And yes, dereferencing a null pointer is pretty much exactly like a NullReferenceException
in C# (or a NullPointerException
in Java), except that the langauge standard is a little more helpful here. In C#, dereferencing a null reference has well-defined behavior: it always throws a NullReferenceException
. There's no way that your program could continue working silently or erase your hard drive like in C (unless there's a bug in the language runtime, but again that's incredibly unlikely as well).
In your particular case the fastest sort is probably the one described in this answer. It is exactly optimized for an array of 6 ints and uses sorting networks. It is 20 times (measured on x86) faster than library qsort. Sorting networks are optimal for sort of fixed length arrays. As they are a fixed sequence of instructions they can even be implemented easily by hardware.
Generally speaking there is many sorting algorithms optimized for some specialized case. The general purpose algorithms like heap sort or quick sort are optimized for in place sorting of an array of items. They yield a complexity of O(n.log(n)), n being the number of items to sort.
The library function qsort() is very well coded and efficient in terms of complexity, but uses a call to some comparizon function provided by user, and this call has a quite high cost.
For sorting very large amount of datas algorithms have also to take care of swapping of data to and from disk, this is the kind of sorts implemented in databases and your best bet if you have such needs is to put datas in some database and use the built in sort.
I think it would make more sense to use "Find" function in Excel instead of For Each loop. It works much much faster and it's designed for such actions. Try this:
Sub FindSomeCells(strSearchQuery As String)
Set SearchRange = Worksheets("Sheet1").Range("A1:A100")
FindWhat = strSearchQuery
Set FoundCells = FindAll(SearchRange:=SearchRange, _
FindWhat:=FindWhat, _
LookIn:=xlValues, _
LookAt:=xlWhole, _
SearchOrder:=xlByColumns, _
MatchCase:=False, _
BeginsWith:=vbNullString, _
EndsWith:=vbNullString, _
BeginEndCompare:=vbTextCompare)
If FoundCells Is Nothing Then
Debug.Print "Value Not Found"
Else
For Each FoundCell In FoundCells
FoundCell.Interior.Color = XlRgbColor.rgbLightGreen
Next FoundCell
End If
End Sub
That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll
function definition:
Function FindAll(SearchRange As Range, _
FindWhat As Variant, _
Optional LookIn As XlFindLookIn = xlValues, _
Optional LookAt As XlLookAt = xlWhole, _
Optional SearchOrder As XlSearchOrder = xlByRows, _

Optional EndsWith As String = vbNullString, _
Optional BeginEndCompare As VbCompareMethod = vbTextCompare) As Range
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result. If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

We run constantly into problems like this. Every solution looks so individual. But looking at php, we have a way dealing with different formats. And there is a port of php's strtotime function at https://locutus.io/php/datetime/strtotime/. A small open source npm package from me as an alternative way:
<script type="module">
import { datebob } from "@dipser/datebob.js";
console.log( datebob('Sun May 11, 2014').format('Y-m-d') );
</script>
See datebob.js
An easy way is to convert the dates into milliseconds after January 1, 1970 (use Date.getTime()) and then compare these values.
To make a dropdown list you need two properties:
In your case you only have a list of string which cannot be exploited to create a usable drop down list.
While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:
@model List<string>
@Html.DropDownList(
"Foo",
new SelectList(
Model.Select(x => new { Value = x, Text = x }),
"Value",
"Text"
)
)
where Foo
will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:
<select name="Foo" id="Foo">
<option value="item 1">item 1</option>
<option value="item 2">item 2</option>
<option value="item 3">item 3</option>
...
</select>
This being said a far better view model for a drop down list is the following:
public class MyListModel
{
public string SelectedItemId { get; set; }
public IEnumerable<SelectListItem> Items { get; set; }
}
and then:
@model MyListModel
@Html.DropDownListFor(
x => x.SelectedItemId,
new SelectList(Model.Items, "Value", "Text")
)
and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId
property of this view model to the corresponding Value
of some element in the Items
collection.
"How do I create an initial database ?"
You created a database when you installed XE. At some point the installation process prompted you to enter a password for the SYSTEM account. Use that to connect to the XE database using the SQL commandline on the application menu.
The XE documentation is online and pretty helpful. Find it here.
It's worth mentioning that 11g XE has several limitations, one of which is only one database per server. So using the pre-installed database is the sensible option.
this code works and dont throw any exception:
Session.Abandon();
Session["tempKey1"] = "tempValue1";
One thing to note here that Session.Clear remove items immediately but Session.Abandon marks the session to be abandoned at the end of the current request. That simply means that suppose you tried to access value in code just after the session.abandon command was executed, it will be still there. So do not get confused if your code is just not working even after issuing session.abandon command and immediately doing some logic with the session.
Typical usage might look like:
i=0
echo -e "hello1\nhello2\nhello3" | while read str ; do
echo "$((++i)): $str"
done
and output
1: hello1
2: hello2
3: hello3
Yes, it is possible to run PowerShell through the run window. However, it would be burdensome and you will need to enter in the password for computer. This is similar to how you will need to set up when you run cmd:
runas /user:(ComputerName)\(local admin) powershell.exe
So a basic example would be:
runas /user:MyLaptop\[email protected] powershell.exe
You can find more information on this subject in Runas.
However, you could also do one more thing :
then your system will execute the elevated powershell.
Deleting and dropping outliers I believe is wrong statistically. It makes the data different from original data. Also makes data unequally shaped and hence best way is to reduce or avoid the effect of outliers by log transform the data. This worked for me:
np.log(data.iloc[:, :])
In C# 8.0 you can get the first five characters of a string like so
string str = data[0..5];
Here is some more information about Indices And Ranges
If your string is
foo="US/Central - 10:26 PM (CST)"
then
echo "${foo}" | cut -d ' ' -f3
will do the job.
Simply replace image/jpeg
with application/octet-stream
. The client would not recognise the URL as an inline-able resource, and prompt a download dialog.
A simple JavaScript solution would be:
//var img = reference to image
var url = img.src.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);
// Or perhaps: location.href = url;
// Or even setting the location of an <iframe> element,
Another method is to use a blob:
URI:
var img = document.images[0];
img.onclick = function() {
// atob to base64_decode the data-URI
var image_data = atob(img.src.split(',')[1]);
// Use typed arrays to convert the binary data to a Blob
var arraybuffer = new ArrayBuffer(image_data.length);
var view = new Uint8Array(arraybuffer);
for (var i=0; i<image_data.length; i++) {
view[i] = image_data.charCodeAt(i) & 0xff;
}
try {
// This is the recommended method:
var blob = new Blob([arraybuffer], {type: 'application/octet-stream'});
} catch (e) {
// The BlobBuilder API has been deprecated in favour of Blob, but older
// browsers don't know about the Blob constructor
// IE10 also supports BlobBuilder, but since the `Blob` constructor
// also works, there's no need to add `MSBlobBuilder`.
var bb = new (window.WebKitBlobBuilder || window.MozBlobBuilder);
bb.append(arraybuffer);
var blob = bb.getBlob('application/octet-stream'); // <-- Here's the Blob
}
// Use the URL object to create a temporary URL
var url = (window.webkitURL || window.URL).createObjectURL(blob);
location.href = url; // <-- Download!
};
You should use a simple IF
statement
List<String> data = GetData();
if (data.Count == 0)
throw new Exception("Data Empty!");
PopulateGrid();
ShowGrid();
In my case problem was in method type, should be HttpPOST but there was HttpGET Once I changed that, everything starts work.
jQuery's attr
method returns the value of the attribute:
The
.attr()
method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's.each()
or.map()
method.
All you need is:
$('html').attr('lang') == 'fr-FR'
However, you might want to do a case-insensitive match:
$('html').attr('lang').toLowerCase() === 'fr-fr'
jQuery's val
method returns the value of a form element.
The
.val()
method is primarily used to get the values of form elements such asinput
,select
andtextarea
. In the case of<select multiple="multiple">
elements, the.val()
method returns an array containing each selected option; if no option is selected, it returnsnull
.

for X,Y in data:
scatter(X, Y, c=numpy.random.random(3))
You can use the exif-js library in combination with the HTML5 File API: http://jsfiddle.net/xQnMd/1/.
$("input").change(function() {
var file = this.files[0]; // file
fr = new FileReader; // to read file contents
fr.onloadend = function() {
// get EXIF data
var exif = EXIF.readFromBinaryFile(new BinaryFile(this.result));
// alert a value
alert(exif.Make);
};
fr.readAsBinaryString(file); // read the file
});
You can do it with anchor tags using css3 :target
pseudo-selector, this selector is going to be triggered when the element with the same id as the hash of the current URL get an match. Example
Knowing this, we can combine this technique with the use of proximity selectors like "+" and "~" to select any other element through the target element who id get match with the hash of the current url. An example of this would be something like what you are asking.

var string = ' ';

Therefore, a simple branching construct will suffice for the test.
if(string) {
// string is not empty
}
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.

I don't think you can give a path to curl, but you can CD to the location, download and CD back.
cd target/path && { curl -O URL ; cd -; }
Or using subshell.
(cd target/path && curl -O URL)
Both ways will only download if path exists. -O
keeps remote file name. After download it will return to original location.
If you need to set filename explicitly, you can use small -o
option:
curl -o target/path/filename URL
This is pretty easy to accomplish with a decorator.

Undiplomatic answer: You're probably looking for an extended persistence context. This is one of the main reasons behind the Seam Framework... If you're struggling to use Hibernate in Spring in particular, check out this piece of Seam's docs.
Diplomatic answer: This is described in the Hibernate docs. If you need more clarification, have a look at Section 9.3.2 of Java Persistence with Hibernate called "Working with Detached Objects." I'd strongly recommend you get this book if you're doing anything more than CRUD with Hibernate.
If you have installed mysql using Homebrew by specifying a version then mysql_config would be present here. - /usr/local/Cellar/[email protected]/5.6.47/bin
you can find the path of the sql bin by using ls command in /usr/local/ directory
/usr/local/Cellar/[email protected]/5.6.47/bin
Add the path to bash profile like this.
nano ~/.bash_profile
export PATH="/usr/local/Cellar/[email protected]/5.6.47/bin:$PATH"

Heapsort implementation. An O(n log(n)) (both average and worst case), in place, unstable sorting algorithm.
Use with: Call HeapSort(A)
, where A
is a one dimensional array of variants, with Option Base 1
.
Sub SiftUp(A() As Variant, I As Long)
Dim K As Long, P As Long, S As Variant
K = I
While K > 1
P = K \ 2
If A(K) > A(P) Then
S = A(P): A(P) = A(K): A(K) = S
K = P
Else
Exit Sub
End If
Wend
End Sub
Sub SiftDown(A() As Variant, I As Long)
Dim K As Long, L As Long, S As Variant
K = 1
Do
L = K + K
If L > I Then Exit Sub
If L + 1 <= I Then
If A(L + 1) > A(L) Then L = L + 1
End If
If A(K) < A(L) Then
S = A(K): A(K) = A(L): A(L) = S
K = L
Else
Exit Sub
End If
Loop
End Sub
Sub HeapSort(A() As Variant)
Dim N As Long, I As Long, S As Variant
N = UBound(A)
For I = 2 To N
Call SiftUp(A, I)
Next I
For I = N To 2 Step -1
S = A(I): A(I) = A(1): A(1) = S
Call SiftDown(A, I - 1)
Next
End Sub
I still remember the first weeks of my programming courses and I totally understand how you feel. Here is the code that solves your problem. In order to learn from this answer, try to run it adding several 'print' in the loop, so you can see the progress of the variables.
import java.util.*;
import java.lang.*;
public class foo
{
public static void main(String[] args)
{
double[] alpha = new double[50];
int count = 0;
for (int i=0; i<50; i++)
{
// System.out.print("variable i = " + i + "\n");
if (i < 25)
{
alpha[i] = i*i;
}
else {
alpha[i] = 3*i;
}
if (count < 10)
{
System.out.print(alpha[i]+ " ");
}
else {
System.out.print("\n");
System.out.print(alpha[i]+ " ");
count = 0;
}
count++;
}
System.out.print("\n");
}
}
From my experience, the problem not with EF, but with ORM approach itself.
In general all ORMs suffers from N+1 problem not optimized queries and etc. My best guess would be to track down queries that causes performance degradation and try to tune-up ORM tool, or rewrite that parts with SPROC.

As some answers mention, localStorage is a good option and you can certainly do it yourself, but if you're looking for a polished option, there is already a project on GitHub that does this called garlic.js.
Swift 5 for cocoa
// Getting the Contents of a Directory in a Single Batch Operation
let bundleRoot = Bundle.main.bundlePath
let url = URL(string: bundleRoot)
let properties: [URLResourceKey] = [ URLResourceKey.localizedNameKey, URLResourceKey.creationDateKey, URLResourceKey.localizedTypeDescriptionKey]
if let src = url{
do {
let paths = try FileManager.default.contentsOfDirectory(at: src, includingPropertiesForKeys: properties, options: [])
for p in paths {

I had to move domain, username, password from
client.ClientCredentials.UserName.UserName = domain + "\\" + username; client.ClientCredentials.UserName.Password = password
to
client.ClientCredentials.Windows.ClientCredential.UserName = username; client.ClientCredentials.Windows.ClientCredential.Password = password; client.ClientCredentials.Windows.ClientCredential.Domain = domain;
Set the Credentials property before sending the message.
The "no frills" options are as follows:
ActiveSheet.Name = "New Name"
and
Sheets("Sheet2").Name = "New Name"
You can also check out recording macros and seeing what code it gives you, it's a great way to start learning some of the more vanilla functions.
For a Ruby on Rails application, I was able to prevent a layout from loading by specifying
render layout: false
in the controller action that I wanted to respond with ajax html.
This will open a second cmd.exe window. If you want it to go away, replace the /K with /C.
Obviously, replace new_file_loc with whatever your new file location will be.
@echo off
for /F %%i in ('dir /B /O:-D *.txt') do (
call :open "%%i"
exit /B 0
)
:open
start "window title" "cmd /K copy %~1 new_file_loc"
exit /B 0
I've not tried to run below, though. I think this's a tricky way.
map{print $_;} @array;
Here's what I did:
I created an IBAction in the header .h files as follows:
- (IBAction)openDaleDietrichDotCom:(id)sender;
I added a UIButton on the Settings page containing the text that I want to link to.
I connected the button to IBAction in File Owner appropriately.
Then implement the following:
Objective-C
- (IBAction)openDaleDietrichDotCom:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.daledietrich.com"]];
}
Swift
(IBAction in viewController, rather than header file)
if let link = URL(string: "https://yoursite.com") {
UIApplication.shared.open(link)
}
Try > workdirectory/filename.txt
This would:
You can consider it equivalent to:
rm -f workdirectory/filename.txt; touch workdirectory/filename.txt
location.href = "Pagename.html";
Actually if you are waiting for response from a server it should be done programatically. You may create a progress dialog and dismiss it, but then again that is not "the android way".
Currently the recommended method is to use a DialogFragment :
public class MySpinnerDialog extends DialogFragment {
public MySpinnerDialog() {
// use empty constructors. If something is needed use onCreate's
}
@Override
public Dialog onCreateDialog(final Bundle savedInstanceState) {
_dialog = new ProgressDialog(getActivity());
this.setStyle(STYLE_NO_TITLE, getTheme()); // You can use styles or inflate a view
_dialog.setMessage("Spinning.."); // set your messages if not inflated from XML
_dialog.setCancelable(false);
return _dialog;
}
}
Then in your activity you set your Fragment manager and show the dialog once the wait for the server started:
FragmentManager fm = getSupportFragmentManager();
MySpinnerDialog myInstance = new MySpinnerDialog();
}
myInstance.show(fm, "some_tag");
Once your server has responded complete you will dismiss it:
myInstance.dismiss()
Remember that the progressdialog is a spinner or a progressbar depending on the attributes, read more on the api guide
public static void ClearLine(int lines = 1)
{
for (int i = 1; i <= lines; i++)

Console.SetCursorPosition(0, Console.CursorTop - 1);
}

For this particular question, the standard suggestion of java.text.SimpleDateFormat
works, but has the unfortunate side effect that SimpleDateFormat
is not thread-safe and can be the source of particularly nasty problems since it'll corrupt your output in multi-threaded scenarios, and you won't get any exceptions!
I would strongly recommend looking at Joda for anything like this. Why ? It's a much richer and more intuitive time/date library for Java than the current library (and the basis of the up-and-coming new standard Java date/time library, so you'll be learning a soon-to-be-standard API).
try this
echo $sqlupdate1 = "UPDATE table SET commodity_quantity=$qty WHERE user='".$rows['user']."' ";
I think you mean to put the rolling of the random a,b,c, etc within the loop:
a = None # initialise
while not (a in winning_numbers):
# keep rolling an a until you get one not in winning_numbers
a = random.randint(1,30)
winning_numbers.append(a)
Otherwise, a
will be generated just once, and if it is in winning_numbers
already, it won't be added. Since the generation of a
is outside the while
(in your code), if a
is already in winning_numbers
then too bad, it won't be re-rolled, and you'll have one less winning number.
That could be what causes your error in if guess[i] == winning_numbers[i]
. (Your winning_numbers
isn't always of length 5).
Yes this is good. Tutorials are not always consize and neat. Not only that, creating local variables is waste of space and inefficient
Use geom_text
, with aes
label. You can play with hjust, vjust
to adjust text position.
ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
geom_point() +geom_text(aes(label=Name),hjust=0, vjust=0)
ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
geom_point() +
geom_text(aes(label=ifelse(PTS>24,as.character(Name),'')),hjust=0,vjust=0)

I was trying to figure this out myself recently, and I came up with a good solution that works perfectly in my browser (Chrome 51) and supports dynamic column widths. I should mention that after I independently derived my answer I also found a similar technique described elsewhere on the web...
The trick is to use two identical tables positioned on top of one another. The lower table is visible and the upper table is invisible expect for the header. The upper table also has pointer-events: none
set on the tbody so mouse interactions hit the underneath table. This way the lower table scrolls under the upper table's header.
For everything to layout and resize properly (when the user adjusts screen width for instance), both tables need to have the same scrollbar behavior. However, the upper table's scroll bar is ignored thanks to the pointer-events: none
and can be made invisible with:
<style>
.hiddenScrollbar::-webkit-scrollbar {
background-color: transparent;
}
</style>

Caveats: More work is required to prove this works in other browsers. Also I was rather liberal in mixing inline and stylesheet styles. However I believe the general concept is the best way of doing this since if the target browser supports it. The only functionality/display issues are that if you want a horizontal scroll bar, the vertical scroll bar can get scrolled out of view (as shown in the snippet). You can still scroll with the mouse wheel though. Additionally you can't have a transparent background on the header (otherwise the underneath table would show through). Finally you need a way to generate two identical tables. Personally I am using react.js and it is easy to do it with react, but php or other server-side generation or javascript will also work.
[HttpPost] // it use when you write logic on button click event
public ActionResult DemoInsert(EmployeeModel emp)
{
Employee emptbl = new Employee(); // make object of table
emptbl.EmpName = emp.EmpName;
emptbl.EmpAddress = emp.EmpAddress; // add if any field you want insert
dbc.Employees.Add(emptbl); // pass the table object
dbc.SaveChanges();
return View();
}
Yes. It is done with a filter on the appender.
Here is the appender configuration I normally use, limited to only INFO level.
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="${HOMEDRIVE}\\PI.Logging\\PI.ECSignage.${COMPUTERNAME}.log" />
<appendToFile value="true" />
<maxSizeRollBackups value="30" />
<maximumFileSize value="5MB" />
<rollingStyle value="Size" /> <!--A maximum number of backup files when rolling on date/time boundaries is not supported. -->
<staticLogFileName value="false" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date{yyyy-MM-dd HH:mm:ss.ffff} [%2thread] %-5level %20.20type{1}.%-25method at %-4line| (%-30.30logger) %message%newline" />
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="INFO" />
</filter>
</appender>
not sure if this question is still open. But I solved the issue by switching to a different usb cable. hopefully, this can save you a couple hours. lol
Just to add to @Nathan Hughes's excellent answer:
The return
statement can be used as a kind of control flow. By putting one (or more) return
statements in the middle of a function, we can say: "stop executing this function. We've either got what we wanted or something's gone wrong!"
Here's an example:
>>> def make_3_characters_long(some_string):
... if len(some_string) == 3:
... return False
... if str(some_string) != some_string:
... return "Not a string!"
... if len(some_string) < 3:
... return ''.join(some_string,'x')[:,3]
... return some_string[:,3]
...
>>> threechars = make_3_characters_long('xyz')
>>> if threechars:
... print threechars
... else:
... print "threechars is already 3 characters long!"
...
threechars is already 3 characters long!
See the Code Style section of the Python Guide for more advice on this way of using return
.
foreach($test_package_data as $key=>$data ) {
$category_detail_arr = $test_package_data[$key]['category_detail'];
foreach( $category_detail_arr as $i=>$value ) {
$test_package_data[$key]['category_detail'][$i]['count'] = $some_value;////<----Here
}
}
I know it has been a long time since this question has been asked but I thought I might add to everyone else's answer and share a blog post that I think explain the solution in a very concise way.
Here is the link
employ_data = open('/tmp/EmployData.csv', 'w')
csvwriter = csv.writer(employ_data)
count = 0
for emp in emp_data:
if count == 0:
header = emp.keys()
csvwriter.writerow(header)
count += 1
csvwriter.writerow(emp.values())
employ_data.close()
The fact that your method does not use the self
argument (which is a reference to the instance that the method is attached to) doesn't mean you can leave it out. It always has to be there, because Python is always going to try to pass it in.
You can try this:
You must follow the following format
$('element,id,class').on('click', function(){....});
*JQuery code*
$('body').addClass('.anything').on('click', function(){
//do some code here i.e
alert("ok");
});
echo 0.0.0.0 websitename.com >> %WINDIR%\System32\Drivers\Etc\Hosts
the >>
appends the output of echo
to the file.
Note that there are two reasons this might not work like you want it to. You may be aware of these, but I mention them just in case.
First, it won't affect a web browser, for example, that already has the current, "real" IP address resolved. So, it won't always take effect right away.
Second, it requires you to add an entry for every host name on a domain; just adding websitename.com
will not block www.websitename.com
, for example.
I don't know if this is the correct way however I did this:
<div class="control-group">
<label class="control-label" for="id1">Label:</label>
<div class="controls">
<textarea id="id1" class="textareawidth" rows="10" name="anyname">value</textarea>
</div>
</div>
and put this in my bootstrapcustom.css file:
@media (min-width: 768px) {
.textareawidth {
width:500px;
}
}
@media (max-width: 767px) {
.textareawidth {
}
}
This way it resizes based on the viewport. Seems to line everything up nicely on a big browser and on a small mobile device.
First of all, there is no difference between View.OnClickListener
and OnClickListener
. If you just use View.OnClickListener
directly, then you don't need to write-
import android.view.View.OnClickListener
You set an OnClickListener instance (e.g. myListener
named object)as the listener to a view via setOnclickListener()
. When a click
event is fired, that myListener

Hope this helps you.
Nowadays, in 90% of case if you working with URL in Python you probably use python-requests. Hence the question here - why not reuse URL validation from requests?
from requests.models import PreparedRequest
import requests.exceptions
def check_url(url):
prepared_request = PreparedRequest()
try:
prepared_request.prepare_url(url, None)
return prepared_request.url
except requests.exceptions.MissingSchema, e:
raise SomeException
Features:
This should do it (not tested):
animals[2...3] = []
Edit: and you need to make it a var
, not a let
, otherwise it's an immutable constant.
Providing javac
is set up through /etc/alternatives/javac
, you can add to your .bash_profile:
JAVA_HOME=$(l=$(which javac) ; while : ; do nl=$(readlink ${l}) ; [ "$nl" ] || break ; l=$nl ; done ; echo $(cd $(dirname $l)/.. ; pwd) )
export JAVA_HOME
Here are two methods, one sweet and simple(and conceptual), the other more formal and can be extended in a variety of situations, after having read a dataset.
Method 1: Conceptual
X2=[]
X1=[1,2,3]
X2.append(X1)
X3=[4,5,6]
X2.append(X3)
X2 thus has [[1,2,3],[4,5,6]] ie a list of lists.
Method 2 : Formal and extensible
Another elegant way to store a list as a list of lists of different numbers - which it reads from a file. (The file here has the dataset train) Train is a data-set with say 50 rows and 20 columns. ie. Train[0] gives me the 1st row of a csv file, train[1] gives me the 2nd row and so on. I am interested in separating the dataset with 50 rows as one list, except the column 0 , which is my explained variable here, so must be removed from the orignal train dataset, and then scaling up list after list- ie a list of a list. Here's the code that does that.
Note that I am reading from "1" in the inner loop since I am interested in explanatory variables only. And I re-initialize X1=[] in the other loop, else the X2.append([0:(len(train[0])-1)]) will rewrite X1 over and over again - besides it more memory efficient.
X2=[]
for j in range(0,len(train)):
X1=[]
for k in range(1,len(train[0])):
txt2=train[j][k]
X1.append(txt2)
X2.append(X1[0:(len(train[0])-1)])
For me this is the simplest solution to add a close button in a popover.
HTML:
<button type="button" id="popover" class="btn btn-primary" data-toggle="popover" title="POpover" data-html="true">
Show popover
</button>
<div id="popover-content" style="display:none">
<!--Your content-->
<button type="submit" class="btn btn-outline-primary" id="create_btn">Create</button>
<button type="button" class="btn btn-outline-primary" id="close_popover">Cancel</button>
</div>
Javascript:
document.addEventListener("click",function(e){
// Close the popover
if (e.target.id == "close_popover"){
$("[data-toggle=popover]").popover('hide');
}
});
This will depend on the database but for SQL Server, this could be achieved as follows:
alter table Example
add NewColumn int identity(1,1)
A transaction is a unit of work that you want to treat as "a whole." It has to either happen in full or not at all.
A classical example is transferring money from one bank account to another. To do that you have first to withdraw the amount from the source account, and then deposit it to the destination account. The operation has to succeed in full. If you stop halfway, the money will be lost, and that is Very Bad.
In modern databases transactions also do some other things - like ensure that you can't access data that another person has written halfway. But the basic idea is the same - transactions are there to ensure, that no matter what happens, the data you work with will be in a sensible state. They guarantee that there will NOT be a situation where money is withdrawn from one account, but not deposited to another.
If you're looking for a way of applying the "static" keyword to a class, like you can in C# for example
static classes are just the compiler hand-holding you and stopping you from writing any instance methods/variables.
If you just write a normal class without any instance methods/variables, it's the same thing, and this is what you'd do in C++
NSString *deviceType = [UIDevice currentDevice].model;
Just use a bytearray()
which is a list of bytes.
Python2:
s = "ABCD"
b = bytearray()
b.extend(s)
Python3:
s = "ABCD"
b = bytearray()
b.extend(map(ord, s))
By the way, don't use str
as a variable name since that is builtin.
...How can I step through my javascript code line by line using Google Chromes developer tools without it going into javascript libraries?...
For the record: At this time (Feb/2015) both Google Chrome and Firefox have exactly what you (and I) need to avoid going inside libraries and scripts, and go beyond the code that we are interested, It's called Black Boxing:
When you blackbox a source file, the debugger will not jump into that file when stepping through code you're debugging.

jQuery has some issues loading binary data using AJAX requests, as it does not yet implement some HTML5 XHR v2 capabilities, see this enhancement request and this discussion
Given that, you have one of two solutions:
First solution, abandon JQuery and use XMLHTTPRequest
Go with the native HTMLHTTPRequest, here is the code to do what you need
var req = new XMLHttpRequest();
req.open("GET", "/file.pdf", true);
req.responseType = "blob";
req.onload = function (event) {
var blob = req.response;
console.log(blob.size);
var link=document.createElement('a');
link.href=window.URL.createObjectURL(blob);
link.download="Dossier_" + new Date() + ".pdf";
link.click();
};
req.send();
Second solution, use the jquery-ajax-native plugin
The plugin can be found here and can be used to the XHR V2 capabilities missing in JQuery, here is a sample code how to use it
$.ajax({
dataType: 'native',
url: "/file.pdf",
xhrFields: {
responseType: 'blob'
},
success: function(blob){
console.log(blob.size);
var link=document.createElement('a');
link.href=window.URL.createObjectURL(blob);
link.download="Dossier_" + new Date() + ".pdf";
link.click();
}
});
If your plan is to deploy to an IIS that has an Application Pool running in .net 4.0 you will need to cleanup the web.config that includes all the section Definitions that point to .net 3.5. The reason this fails is because these section definitions are already included in the root web.config in .NET 4.0 (see %windir%\microsoft.net\framework\v4.0.30319\config\machine.config) that include all the system.web.extensions declared already.
Another quick fix is to have the application pool set to 2.0 just as your development machine appears to have,.
I had the same problem... solved it by adding the code shown below to the Into "$(document).ready" part of my "functions.js" file which is included in every page footer. It's pretty simple. It gets the full current URL of the displayed page and compares it to the full anchor href URL. If they are the same, set anchor (li) parent as active. And do this only if anchor href value is not "#", then the bootstrap will solve it.
$(document).ready(function () {
$(function(){
var current_page_URL = location.href;
$( "a" ).each(function() {
if ($(this).attr("href") !== "#") {
var target_URL = $(this).prop("href");
if (target_URL == current_page_URL) {
$('nav a').parents('li, ul').removeClass('active');
$(this).parent('li').addClass('active');
return false;
}
}
}); }); });
I like short version: mvn clean install -DskipTests
It's work too: mvn clean install -DskipTests=true
If you absolutely must, you can also use the maven.test.skip property to skip compiling the tests. maven.test.skip is honored by Surefire, Failsafe and the Compiler Plugin.
mvn clean install -Dmaven.test.skip=true
and you can add config in maven.xml

I suggest you to use Message Properte from The Exception Object Like below code
try
{
object result = processClass.InvokeMethod("Create", methodArgs);
}
catch (Exception e)
{
//use Console.Write(e.Message); from Console Application
//and use MessageBox.Show(e.Message); from WindowsForm and WPF Application
}
You can use StringFormat in Silverlight 4 to provide a custom formatting of the value you bind to.
The date formatting has a huge range of options.
For the DateTime of “April 17, 2004, 1:52:45 PM”
You can either use a set of standard formats (standard formats)…
StringFormat=f : “Saturday, April 17, 2004 1:52 PM”
StringFormat=g : “4/17/2004 1:52 PM”
StringFormat=m : “April 17”
StringFormat=y : “April, 2004”
StringFormat=t : “1:52 PM”
StringFormat=u : “2004-04-17 13:52:45Z”
StringFormat=o : “2004-04-17T13:52:45.0000000”
… or you can create your own date formatting using letters (custom formats)
StringFormat=’MM/dd/yy’ : “04/17/04”
StringFormat=’MMMM dd, yyyy g’ : “April 17, 2004 A.D.”
StringFormat=’hh:mm:ss.fff tt’ : “01:52:45.000 PM”
Use the following steps to select the database:
mysql -u username -p
it will prompt for password, Please enter password. Now list all the databases
show databases;
select the database which you want to select using the command:
use databaseName;
select data from any table:
select * from tableName limit 10;
You can select your database using the command use photogallery;
Thanks !
With the --squash
flag it looks like two parallel branches with no relation:
Sorting commits related to date looks like:
Personally, i don't like --squash option, try this trick, maybe it fits your needs, i use it for small projects:
null commit for intentionally merge conflict, name it anything you prefer
What exactly do you want to know?
The shared library soname? That's part of the filename, libstdc++.so.6
, or shown by readelf -d /usr/lib64/libstdc++.so.6 | grep soname
.
The minor revision number? You should be able to get that by simply checking what the symlink points to:
$ ls -l /usr/lib/libstdc++.so.6
lrwxrwxrwx. 1 root root 19 Mar 23 09:43 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.16
That tells you it's 6.0.16, which is the 16th revision of the libstdc++.so.6
version, which corresponds to the GLIBCXX_3.4.16
symbol versions.
Or do you mean the release it comes from? It's part of GCC so it's the same version as GCC, so unless you've screwed up your system by installing unmatched versions of g++
and libstdc++.so
you can get that from:
$ g++ -dumpversion
4.6.3
Or, on most distros, you can just ask the package manager. On my Fedora host that's
$ rpm -q libstdc++
libstdc++-4.6.3-2.fc16.x86_64
libstdc++-4.6.3-2.fc16.i686
As other answers have said, you can map releases to library versions by checking the ABI docs
There has been some major changes in ms 2008 -> Might be worth considering the following article when making a decisions on what data type to use. http://msdn.microsoft.com/en-us/library/ms143432.aspx
Bytes per
See http://caniuse.com/#search=minlength. Some browsers may not support this attribute.
If the value of the "type" is one of them:
text, email, search, password, tel, or URL (warning: not include number | no browser support "tel" now - 2017.10)
Use the minlength(/ maxlength) attribute. It specifies the minimum number of characters.
For example,
<input type="text" minlength="11" maxlength="11" pattern="[0-9]*" placeholder="input your phone number">
Or use the "pattern" attribute:
<input type="text" pattern="[0-9]{11}" placeholder="input your phone number">
If the "type" is number, although minlength(/ maxlength) is not be supported, you can use the min(/ max) attribute instead of it.
For example,
<input type="number" min="100" max="999" placeholder="input a three-digit number">
The reason that this is happening is because the stack panel measures every child element with positive infinity as the constraint for the axis that it is stacking elements along. The child controls have to return how big they want to be (positive infinity is not a valid return from the MeasureOverride in either axis) so they return the smallest size where everything will fit. They have no way of knowing how much space they really have to fill.
If your view doesn’t need to have a scrolling feature and the answer above doesn't suit your needs, I would suggest implement your own panel. You can probably derive straight from StackPanel and then all you will need to do is change the ArrangeOverride method so that it divides the remaining space up between its child elements (giving them each the same amount of extra space). Elements should render fine if they are given more space than they wanted, but if you give them less you will start to see glitches.
If you want to be able to scroll the whole thing then I am afraid things will be quite a bit more difficult, because the ScrollViewer gives you an infinite amount of space to work with which will put you in the same position as the child elements were originally. In this situation you might want to create a new property on your new panel which lets you specify the viewport size, you should be able to bind this to the ScrollViewer’s size. Ideally you would implement IScrollInfo, but that starts to get complicated if you are going to implement all of it properly.
A more readable version of the ternary might look like:
var x = this.dealer;
alert(t < 1 || t > 11
? 'none'
: t < 5
? 'less than five'
: t <= 8
? 'between 5 and 8'
: 'Between 9 and 11');
Well getheight gets the height, and getwidth gets the width. But you're calling those methods too soon. If you're calling them in oncreate or onresume, the view isn't drawn yet. You have to call it after the view has been drawn.
