it's worth noting that the Win32_Product WMI class represents products as they are installed by Windows Installer. not every application use windows installer
however "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" represents applications for 32 bit. For 64 bit you also need to traverse "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" and since not every software has a 64 bit version the total applications installed are a union of keys on both locations that have "UninstallString" Value with them.
but the best options remains the same .traverse registry keys is a better approach since every application have an entry in registry[including the ones in Windows Installer].however the registry method is insecure as if anyone removes the corresponding key then you will not know the Application entry.On the contrary Altering the HKEY_Classes_ROOT\Installers is more tricky as it is linked with licensing issues such as Microsoft office or other products. for more robust solution you can always combine registry alternative with the WMI.

I use NUnit 3 and tried most of the other solutions I saw here. None of those worked for me.
Even though already selected, reselecting the "Playlist: All Tests" option in test explorer showed all hidden tests in my case. I need to do this after every rebuild.
In my case I had inherited from the IdentityDbContext correctly (with my own custom types and key defined) but had inadvertantly removed the call to the base class's OnModelCreating:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder); // I had removed this
/// Rest of on model creating here.
}
Which then fixed up my missing indexes from the identity classes and I could then generate migrations and enable migrations appropriately.
I would prefer AssertJ for this.
assertThatExceptionOfType(ExpectedException.class)
.isThrownBy(() -> {
// method call
}).withMessage("My message");
In fact the deleteDir function recursively deletes the current directory and its contents. Symbolic links and junctions will not be followed but will be removed.
To delete a specific directory of a workspace wrap the deleteDir step in a dir step.
dir('directoryToDelete') {
deleteDir()
}
The C Programming Language (K&R) would have you check for null == ptr to avoid an accidental assignment.
Visual Studio reads NuGet.Config files from the solution root. Try moving it there instead of placing it in the same folder as the project.
You can also place the file at %appdata%\NuGet\NuGet.Config
and it will be used everywhere.

You can use the following with the first day of the specified month:
datediff(day, @date, dateadd(month, 1, @date))
To make it work for every date:
datediff(day, dateadd(day, 1-day(@date), @date),
dateadd(month, 1, dateadd(day, 1-day(@date), @date)))
According to the manual on json_encode
the method can return a non-string (false):
Returns a JSON encoded string on success or
FALSE
on failure.
When this happens echo json_encode($data)
will output the empty string, which is invalid JSON.
json_encode
will for instance fail (and return false
) if its argument contains a non UTF-8 string.
This error condition should be captured in PHP, for example like this:
<?php
header("Content-Type: application/json");
// Collect what you need in the $data variable.
$json = json_encode($data);
if ($json === false) {
// Avoid echo of empty string (which is invalid JSON), and
// JSONify the error message instead:
$json = json_encode(["jsonError" => json_last_error_msg()]);
if ($json === false) {
// This should not happen, but we go all the way now:
$json = '{"jsonError":"unknown"}';
}
// Set HTTP response status code to: 500 - Internal Server Error
http_response_code(500);
}
echo $json;
?>
Then the receiving end should of course be aware that the presence of the jsonError property indicates an error condition, which it should treat accordingly.
In production mode it might be better to send only a generic error status to the client and log the more specific error messages for later investigation.
Read more about dealing with JSON errors in PHP's Documentation.
select right(rtrim('94342KMR'),3)
This will fetch the last 3 right string.
select substring(rtrim('94342KMR'),1,len('94342KMR')-3)
This will fetch the remaining Characters.
In this part of your SP:
IF @DateFirst <> '' and @DateLast <> ''
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + @DateFirst
+ ' and convert (Date,DateLog) <=''' + @DateLast
you are trying to concatenate strings and datetimes.
As the datetime
type has higher priority than varchar
/nvarchar
, the +
operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= '''
and others) to datetime or numeric values. And fails.
That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.
To amend the situation, you need to add explicit casting of your datetime variables to strings:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst)
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)
You'll also need to add closing single quotes:
set @FinalSQL = @FinalSQL
+ ' or convert (Date,DateLog) >= ''' + convert(date, @DateFirst) + ''''
+ ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''
On Debian-like distributions you set that in /etc/default/tomcat[67]
You need to load your image as bitmap:
Resources res = getResources();
Bitmap bitmap = BitmapFactory.decodeResource(res, R.drawable.your_image);
Then make the bitmap mutable and create a canvas over it:
Canvas canvas = new Canvas(bitmap.copy(Bitmap.Config.ARGB_8888, true));
You then can draw on the canvas.
JSON.stringify(err, Object.getOwnPropertyNames(err))
seems to work
[from a comment by /u/ub3rgeek on /r/javascript] and felixfbecker's comment below
I messed around with this problem for a bit, and found a very simple, 2-line solution, simply replacing the 'http' and all the forward slashes like this:
myFilePath = replace(myFilePath, "/", "\")
myFilePath = replace(myFilePath, "http:", "")
It might not work for everybody, but it worked for me
If you are using a secure site (or wish to cater for both) you may wish to add the following line:
myFilePath = replace(myFilePath, "https:", "")
If you're copying data like that, that probably means your datamodel isn't fully normalized, right? Is it possible to make one list of countries and do a JOIN more?
Instead of a JOIN you could also use virtual tables so you don't have to change the queries in your system.
Personally, I tend to use awk for jobs like this. For example:
ps axu| grep jboss | grep -v grep | awk '{print $5}'
AFAIK, unit testing is NOT functional testing. Let me explain with a small example. You want to test if the login functionality of an email web app is working or not, just as a user would. For that, your functional tests should be like this.
1- existing email, wrong password -> login page should show error "wrong password"!
2- non-existing email, any password -> login page should show error "no such email".
3- existing email, right password -> user should be taken to his inbox page.
4- no @symbol in email, right password -> login page should say "errors in form, please fix them!"
Should our functional tests check if we can login with invalid inputs ? Eg. Email has no @ symbol, username has more than one dot (only one dot is permitted), .com appears before @ etc. ? Generally, no ! That kind of testing goes into your unit tests.
You can check if invalid inputs are rejected inside unit tests as shown in the tests below.
class LoginInputsValidator
method validate_inputs_values(email, password)
1-If email is not like [email protected], then throw error.
2-If email contains abusive words, then throw error.
3-If password is less than 10 chars, throw error.
Notice that the functional test 4 is actually doing what unit test 1 is doing. Sometimes, functional tests can repeat some (not all) of the testing done by unit tests, for different reasons. In our example, we use functional test 4 to check if a particular error message appears on entering invalid input. We don't want to test if all bad inputs are rejected or not. That is the job of unit tests.
An alternative to the rather unintuitive [::-1]
syntax is this:
>>> test = "abcba"
>>> test == ''.join(reversed(test))
True
The reversed
function returns a reversed sequence of the characters in test
.
''.join()
joins those characters together again with nothing in between.
You can not call remote set-url origin
just after git init
, Because the git remote set-url
command will not create origin, but it changes an existing remote repository URL.
so the command git remote set-url
will only work if you've either cloned the repository or manually added a remote called origin.
you can check remote with command git remote -v
it will show remote url after name, or if this command gives error like fatal: Not a git repository (or any of the parent directories): .git
then the repository not exists, so you have to add origin with command git remote add
1. git remote add
This command is used to add a new remote, you can use this command on the terminal, in the directory of your repository.
The git remote add command takes two arguments:
For example:
git remote add origin https://github.com/user/repo.git
2.git remote set-url
The git remote set-url command changes an existing remote repository URL.
The git remote set-url command takes two arguments:
origin
or upstream
are two common choices.For example you can change your remote's URL from SSH to HTTPS with the git remote set-url
command.
git remote set-url origin https://github.com/USERNAME/REPOSITORY.git
you can verify that the remote URL has changed, with command git remote -v
.
note: "origin" is a convention not part of the command. "origin" is the local name of the remote repository. you can use any name instead of "origin".
For example:
git remote add myorigin [email protected]:user/repo.git
git remote set-url myorigin https://github.com/user/repo.git
References from github: remote add, remote set-url
I removed the tag in the .project .

It's worked very well for me.
and of course the following:
var count = $("#myList").children().length;
can be condensed down to: (by removing the 'var' which is not necessary to set a variable)
count = $("#myList").children().length;
however this is cleaner:
count = $("#mylist li").size();
Note: If you have written any crash handler yourself, then the core might not get generated. So search for code with something on the line:
signal(SIGSEGV, <handler> );
so the SIGSEGV will be handled by handler and you will not get the core dump.
Pretty Late answer though. But This has worked for me , and could be useful.
While Using Spring Security ans mockMvc, all you need to is use @WithMockUser annotation like others are mentioned.
Spring security also provides another annotation called @WithAnonymousUser
for testing unauthenticated requests. However you should be careful here. You would be expecting 401, but I got 403 Forbidden Error by default. In actual scenarios, when you are running actual service, It is redirected and you end up getting the correct 401 response code.Use this annotation for anonymous requests.
You may also think of ommitting the annotaions and simply keep it unauthorized. But this usually raises the correct exceptions(like AuthenticationException), but you will get correct status code if it is handled correctly(If you are using custom handler). I used to get 500 for this. So look for the exceptions raised in the debugger, and check if it is handled rightly and returns the correct status code.
So close! os.path.isdir
returns True
if you pass in the name of a directory that currently exists. If it doesn't exist or it's not a directory, then it returns False
.

Was trying to create a string representation of MD5 hash using LINQ, however, none of the answers were LINQ solutions, therefore adding this to the smorgasbord of available solutions.

No. Unfortunately the Request object is only available until the page finishes loading - once it's complete, you'll lose all values in it unless they've been stored somewhere.
If you want to persist attributes through requests you need to either:
<input type="hidden" name="myhiddenvalue" value="<%= request.getParameter("value") %>" />
. This will then be available in the servlet as a request parameter.request.getSession()
- in a JSP this is available as simply session
)I recommend using the Session as it's easier to manage.
Official documentation says, click on a link in a WebView will launch application that handles URLs. You need to override this default behavior
myWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
or if there is no conditional logic in the method simply do this
myWebView.setWebViewClient(new WebViewClient());
Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.
This will be a JRE and JDK package.
There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.
You have a orWhereIn
function in Laravel. It takes the same parameters as the whereIn
function.
It's not in the documentation but you can find it in the laravel API. http://laravel.com/api/4.1/
That should give you this:
$query-> orWhereIn('products.value', $f);
I like using ls
options, for sample:
-l
use a long listing format-t
sort by modification time, newest first-r
reverse order while sorting-F
,--classify
append indicator (one of */=>@|) to entries-h
,--human-readable
with -l and -s, print sizes like 1K 234M 2G etc...
Sometime --color
and all others. (See ls --help
)
This will show files, symlinks, devices, pipe, sockets etc.
so
find /some/path -maxdepth 1 ! -type d
could be sorted by date easily:
find /some/path -maxdepth 1 ! -type d -exec ls -hltrF {} +
or
find /some/path -maxdepth 1 -type f
sorted by size:
find /some/path -maxdepth 1 -type f -exec ls -lSF --color {} +
To not show hidden entries, where name begin by a dot, you could add ! -name '.*'
:
find /some/path -maxdepth 1 ! -type d ! -name '.*' -exec ls -hltrF {} +
Then
You could replace /some/path
by .
to list for current directory or ..
for parent directory.
This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.
It's actually best practice to provide the os with a path link.

The openssl
documentation says that file supplied as the -in
argument must be in PEM format.
Turns out that, contrary to the CA's manual, the certificate returned by the CA which I stored in myCert.cer
is not PEM format rather it is PKCS7.
In order to create my .p12
, I had to first convert the certificate to PEM:
openssl pkcs7 -in myCert.cer -print_certs -out certs.pem
and then execute
openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in certs.pem
You could also just do it in one go, by doing the sort first and using head to take the first 3 of each group.

You want to write a function (a recursive function is easiest, but can easily run out of stack space on deep directories) that will enumerate the children of a directory. If you find a child that is a directory, you recurse on that. Otherwise, you delete the files inside. When you are done, the directory is empty and you can remove it via the syscall.
To enumerate directories on Unix, you can use opendir()
, readdir()
, and closedir()
. To remove you use rmdir()
on an empty directory (i.e. at the end of your function, after deleting the children) and unlink()
on a file. Note that on many systems the d_type
member in struct dirent
is not supported; on these platforms, you will have to use stat()
and S_ISDIR(stat.st_mode)
to determine if a given path is a directory.
On Windows, you will use FindFirstFile()
/FindNextFile()
to enumerate, RemoveDirectory()
on empty directories, and DeleteFile()
to remove files.
Here's an example that might work on Unix (completely untested):
int remove_directory(const char *path) {
DIR *d = opendir(path);
size_t path_len = strlen(path);
int r = -1;
if (d) {
struct dirent *p;
r = 0;
while (!r && (p=readdir(d))) {
int r2 = -1;
char *buf;
size_t len;
/* Skip the names "." and ".." as we don't want to recurse on them. */
if (!strcmp(p->d_name, ".") || !strcmp(p->d_name, ".."))
continue;
len = path_len + strlen(p->d_name) + 2;
buf = malloc(len);
if (buf) {
struct stat statbuf;
snprintf(buf, len, "%s/%s", path, p->d_name);
if (!stat(buf, &statbuf)) {
if (S_ISDIR(statbuf.st_mode))
r2 = remove_directory(buf);
else
r2 = unlink(buf);
}
free(buf);
}
r = r2;
}
closedir(d);
}
if (!r)
r = rmdir(path);
return r;
}
I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
use this on:
$('body').on('focus',".datumwaehlen", function(){
$(this).datepicker({
minDate: -20
});
});
function handler(event) {
var target = $(event.target);
if (!target.is("div.menuWraper")) {
alert("outside");
}
}
$("#myPage").click(handler);
First is correct way of checking whether a field value is null
while later won't work the way you expect it to because null
is special value which does not equal anything, so you can't use equality comparison using =
for it.
So when you need to check if a field value is null
or not, use:
where x is null
instead of:
where x = null
So nicer with Kotlin suger:
private fun isSomePackageInstalled(context: Context, packageName: String): Boolean {
val packageManager = context.packageManager
return runCatching { packageManager.getPackageInfo(packageName, 0) }.isSuccess
}

The short answer is no, you cannot alter the environment of the parent process, but it seems like what you want is an environment with custom environment variables and the shell that the user has chosen.
So why not simply something like
#!/usr/bin/env bash
FOO=foo $SHELL
Then when you are done with the environment, just exit
.
NOTE: This solution "burns the subtitles" into the video, so that every viewer of the video will be forced to see them.
If your ffmpeg has libass enabled at compile time, you can directly do:
ffmpeg -i mymovie.mp4 -vf subtitles=subtitles.srt mysubtitledmovie.mp4
This is the case e.g. for Ubuntu 20.10, you can check if ffmpeg --version
has --enable-libass
.
Otherwise, you can the libass
library (make sure your ffmpeg install has the library in the configuration --enable-libass
).
First convert the subtitles to .ass
format:
ffmpeg -i subtitles.srt subtitles.ass
Then add them using a video filter:
ffmpeg -i mymovie.mp4 -vf ass=subtitles.ass mysubtitledmovie.mp4
this should work, had to try a while too.. :D

Just my take on the matter, three months later:
Jenkins has continued the path well-trodden by the original Hudson with frequent releases including many minor updates.
Oracle seems to have largely delegated work on the future path for Hudson to the Sonatype team, who has performed some significant changes, especially with respect to Maven. They have jointly moved it to the Eclipse foundation.
I would suggest that if you like the sound of:
, then I would suggest Hudson.
Conversely, if you prefer:
then I would suggest Jenkins. (and as a commenter noted, Jenkins now also has "LTS" releases which are maintained on a more "stable" branch)
The conservative course would be to choose Hudson now and migrate to Jenkins if must-have features are unavailable. The dynamic course would be to choose Jenkins now and migrate to Hudson if chasing updates becomes too time-consuming to justify.
I could fix it using below steps.(GlassFish server3.1.2.2 and eclipse Luna 4.4.1)
UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.
If your project uses Maven you can simply include UCanAccess via the following coordinates:
groupId: net.sf.ucanaccess
artifactId: ucanaccess
The following is an excerpt from pom.xml
, you may need to update the <version>
to get the most recent release:
<dependencies>
<dependency>
<groupId>net.sf.ucanaccess</groupId>
<artifactId>ucanaccess</artifactId>
<version>4.0.4</version>
</dependency>
</dependencies>
As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:
UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)
Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like
ucanaccess-4.0.1.jar
/lib/
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.1.6.jar
All you need to do is add all five (5) JARs to your project.
NOTE: Do not add
loader/ucanload.jar
to your build path if you are adding the other five (5) JAR files. TheUcanloadDriver
class is only used in special circumstances and requires a different setup. See the related answer here for details.
Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path...
. Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this
NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.
After adding all five (5) JAR files the "Libraries" folder should look something like this:
IntelliJ IDEA: Choose File > Project Structure...
from the main menu. In the "Libraries" pane click the "Add" (+
) button and add the five (5) JAR files. Once that is done the project should look something like this:
Now "U Can Access" data in .accdb and .mdb files using code like this
// assumes...
// import java.sql.*;
Connection conn=DriverManager.getConnection(
"jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
System.out.println(rs.getString(1));
}
At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.
This worked for me... try it
let image : UIImage = UIImage(named: "LogoName")
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
imageView.contentMode = .scaleAspectFit
imageView.image = image
navigationItem.titleView = imageView
Please make sure both JDK and jre are on same version for example if you have JRE version 1.8.0_201 then JDK version should be 1.8.0_201 version.
Try an LL
suffix on the number, the compiler may be casting it to an intermediate type as part of the parse. See http://gcc.gnu.org/onlinedocs/gcc/Long-Long.html
long long int i2 = 0x0000444400004444LL;
Additionally, the the compiler is discarding the leading zeros, so 0x000044440000
is becoming 0x44440000
, which is a perfectly acceptable 32-bit integer (which is why you aren't seeing any warnings prior to f2
).
Here you have an example working on py2.6 and py3.2:
from scipy.stats import norm
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt
# read data from a text file. One number per line
arch = "test/Log(2)_ACRatio.txt"
datos = []
for item in open(arch,'r'):
item = item.strip()
if item != '':
try:
datos.append(float(item))
except ValueError:
pass
# best fit of data
(mu, sigma) = norm.fit(datos)
# the histogram of the data
n, bins, patches = plt.hist(datos, 60, normed=1, facecolor='green', alpha=0.75)
# add a 'best fit' line
y = mlab.normpdf( bins, mu, sigma)
l = plt.plot(bins, y, 'r--', linewidth=2)
#plot
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title(r'$\mathrm{Histogram\ of\ IQ:}\ \mu=%.3f,\ \sigma=%.3f$' %(mu, sigma))
plt.grid(True)
plt.show()
Marc's answer is of course the right answer. But since he mentioned the shift operators and unsafe code as an alternative. I would like to share a less common alternative. Using a struct with Explicit
layout. This is similar in principal to a C/C++ union
.
Here is an example of a struct that can be used to get to the component bytes of the Int32 data type and the nice thing is that it is two way, you can manipulate the byte values and see the effect on the Int.
using System.Runtime.InteropServices;
[StructLayout(LayoutKind.Explicit)]
struct Int32Converter
{
[FieldOffset(0)] public int Value;
[FieldOffset(0)] public byte Byte1;
[FieldOffset(1)] public byte Byte2;
[FieldOffset(2)] public byte Byte3;
[FieldOffset(3)] public byte Byte4;
public Int32Converter(int value)
{
Byte1 = Byte2 = Byte3 = Byte4 = 0;
Value = value;
}
public static implicit operator Int32(Int32Converter value)
{
return value.Value;
}
public static implicit operator Int32Converter(int value)
{
return new Int32Converter(value);
}
}
The above can now be used as follows
Int32Converter i32 = 256;
Console.WriteLine(i32.Byte1);
Console.WriteLine(i32.Byte2);
Console.WriteLine(i32.Byte3);
Console.WriteLine(i32.Byte4);
i32.Byte2 = 2;
Console.WriteLine(i32.Value);
Of course the immutability police may not be excited about the last possiblity :)
We can also use the readonly only with below attributes -
readonly onclick='return false;'
This is because if we will only use the readonly then radio buttons will be editable. To avoid this situation we can use readonly with above combination. It will restrict the editing and element's values will also passed during form submission.
It is better not to mix up the virtual environments or perform installation on the root directory. Steps I took for hassle free installation are as below. I used conda for installing all my dependencies instead of pip. I'm answering with extra details, because when I tried to install tensor board and tensor flow on my root env, it messed up.
Create a virtual env
conda create --name my_env python=3.6
Activate virtual environment
source activate my_env
Install basic required modules
conda install pandas
conda install tensorflow
Install tensor board
conda install -c condo-forge tensor board
Hope that helps

I know this is an old issue, but people may still face this.
The following checks if the BundleModule exists in web.config and loaded, and sets EnableOptimizations based on its existance.
This way wether it is available or not, the css/js references will work fine. In other words:
If BundleModule is available, the bundeling/optimization will be enabled.
If BundleModule is not available, the bundeling/optimization will be disabled and automatically the full references will be used instead.
Code:
public static void RegisterBundles(BundleCollection bundles)
{
// bundeling code here
// ...
// bundeling code here
bool bundelingModuleIsAvailable = false;
try {
bundelingModuleIsAvailable = HttpContext.Current.ApplicationInstance.Modules.AllKeys.Contains("BundleModule");
}
catch { }
if (!bundelingModuleIsAvailable)
System.Diagnostics.Debug.WriteLine("WARNING : optimization bundle is not added to Web.config!");
BundleTable.EnableOptimizations = bundelingModuleIsAvailable && !Debug_CheckIsRunning();
//Debug_CheckIsRunning is optional, incase you want to disable optimization when debugging yourself
BundleTable.EnableOptimizations = true;
}
private bool Debug_CheckIsRunning()
{//Check if debug is running
string moduleName = System.Diagnostics.Process.GetCurrentProcess().MainModule.ModuleName;
return (moduleName.Contains("iisexpress.exe") || moduleName.Contains(".vshost") || moduleName.Contains("vstest.executionengine") || moduleName.Contains("WebDev.WebServer"));
}
You should be escaping each of these strings (in both snippets) with mysql_real_escape_string()
.
http://us3.php.net/mysql-real-escape-string
The reason your two queries are behaving differently is likely because you have magic_quotes_gpc
turned on (which you should know is a bad idea). This means that strings gathered from $_GET, $_POST and $_COOKIES are escaped for you (i.e., "O'Brien" -> "O\'Brien"
).
Once you store the data, and subsequently retrieve it again, the string you get back from the database will not be automatically escaped for you. You'll get back "O'Brien"
. So, you will need to pass it through mysql_real_escape_string()
.
If you're on Debian 8 (Jessie) Linux, try to cd
into the directory of the 'metropolises.sql'
. Run mysql
and execute SOURCE ./metropolises.sql;
Basically, try the relative path. I tried this and it works.
Note:
After that, Click Apply and OK.
I'm using zip.js and it seems to be quite useful. It's worth a look!
Check the Unzip demo, for example.
try this code...
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffff00">
<ListView
android:id="@+id/android:list"
android:layout_marginTop="2px"
android:layout_marginLeft="2px"
android:layout_marginRight="2px"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@drawable/shape_1"
android:listSelector="@drawable/shape_3"
android:textColor="#ffff00"
android:layout_marginBottom="44px" />
</RelativeLayout>
<p>
is semantically used for text, paragraphs usually.
<div>
is used for a block or area in a webpage. For example it could be used to make the area of a header.
They could probably be used interchangeably, but you shouldn't.
I also faced the same problem where label did not detect autofill and animation for moving label on filling text was overlapping and this solution worked for me.
input:-webkit-autofill ~ label {
top:-20px;
}
Try this:
Select Project_Name, ReleaseDate, TaskName
From DB_Table
Where Project_Name like '{?Pm-?Proj_Name}'
And ReleaseDate >= currentdate
currentdate should be a valid database function or field to work. If you are using MS SQL Server, use GETDATE() instead.
If all you want is to filter records in a subreport based on a parameter from the main report, it might be easier to simply add the table to the subreport, and then create a Project_Name link between the main report and subreport. You can then use the Select Expert to filter the ReleaseDate as well.
You can always try putting this code in your main css without modifying the bootstrap file what is most recommended so you keep consistency if in a future you update the bootstrap file.
.tooltip-inner {
background-color: #FF0000;
}
.tooltip.right .tooltip-arrow {
border-right: 5px solid #FF0000;
}
Notice that this example is for a right tooltip. The tooltip-inner property changes the tooltip BG color, the other one changes the arrow color.
The best way is Mikael Eriksson, if ROW_NUMBER()
is available to you.
The next best is to join on a query, as per Cularis' answer.
Alternatively, the most simple and straight forward way is a correlated-sub-query in the WHERE clause.
SELECT
*
FROM
yourTable AS [data]
WHERE
DateEntered = (SELECT MAX(DateEntered) FROM yourTable WHERE orderNo = [data].orderNo)
Or...
WHERE
ID = (SELECT TOP 1 ID FROM yourTable WHERE orderNo = [data].orderNo ORDER BY DateEntered DESC)
Use the builtin function zip()
:
In Python 3:
z = list(zip(x,y))
In Python 2:
z = zip(x,y)
If you are using plain LINQ-to-objects and don't want to take a dependency on an external library it is not hard to achieve what you want.
The OrderBy()
clause accepts a Func<TSource, TKey>
that gets a sort key from a source element. You can define the function outside the OrderBy()
clause:
Func<Item, Object> orderByFunc = null;
You can then assign it to different values depending on the sort criteria:
if (sortOrder == SortOrder.SortByName)
orderByFunc = item => item.Name;
else if (sortOrder == SortOrder.SortByRank)
orderByFunc = item => item.Rank;
Then you can sort:
var sortedItems = items.OrderBy(orderByFunc);
This example assumes that the source type is Item
that have properties Name
and Rank
.
Note that in this example TKey
is Object
to not constrain the property types that can be sorted on. If the func returns a value type (like Int32
) it will get boxed when sorting and that is somewhat inefficient. If you can constrain TKey
to a specific value type you can work around this problem.
suppose your JAR file is in C:\Documents and Settings\mmeher\Desktop\jar and the JAR file name is xx.jar, then write the below two commands in command prompt:
1> cd C:\Documents and Settings\mmeher\Desktop\jar
2> jar xf xx.jar
Dockerfiles are to build an image for example from a bare bone Ubuntu, you can add mysql
called mySQL
on one image and mywordpress
on a second image called mywordpress
.
Compose YAML files are to take these images and run them cohesively.
For example, if you have in your docker-compose.yml
file a service called db
:
services:
db:
image: mySQL --- image that you built.
and a service called wordpress such as:
wordpress:
image: mywordpress
then inside the mywordpress container you can use db
to connect to your mySQL container. This magic is possible because your docker host create a network bridge (network overlay).
I did solved using this jquery for Github
<script src="http://code.jquery.com/jquery-migrate-1.0.0.js"></script>
Please Refer this link for more info. https://github.com/Studio-42/elFinder/issues/469
You could use the highlight effect in jQuery UI to achieve the same, I guess.
\begin{tikzpicture}
\tikzstyle{every node}=[font=\fontsize{30}{30}\selectfont]
\end{tikzpicture}
It works best this way. Make sure that both files are on the server. When calling the html page, make use of the web address like: http:://localhost/myhtmlfile.html
, and not, C::///users/myhtmlfile.html
. Make usre as well that the url passed to the json is a web address as denoted below:
$(function(){
$('#typeahead').typeahead({
source: function(query, process){
$.ajax({
url: 'http://localhost:2222/bootstrap/source.php',
type: 'POST',
data: 'query=' +query,
dataType: 'JSON',
async: true,
success: function(data){
process(data);
}
});
}
});
});
If your Python datetime object is timezone-aware than you should be careful to avoid errors around DST transitions (or changes in UTC offset for other reasons):
from datetime import datetime, timedelta
from tzlocal import get_localzone # pip install tzlocal
DAY = timedelta(1)
local_tz = get_localzone() # get local timezone
now = datetime.now(local_tz) # get timezone-aware datetime object
day_ago = local_tz.normalize(now - DAY) # exactly 24 hours ago, time may differ
naive = now.replace(tzinfo=None) - DAY # same time
yesterday = local_tz.localize(naive, is_dst=None) # but elapsed hours may differ
In general, day_ago
and yesterday
may differ if UTC offset for the local timezone has changed in the last day.
For example, daylight saving time/summer time ends on Sun 2-Nov-2014 at 02:00:00 A.M. in America/Los_Angeles timezone therefore if:
import pytz # pip install pytz
local_tz = pytz.timezone('America/Los_Angeles')
now = local_tz.localize(datetime(2014, 11, 2, 10), is_dst=None)
# 2014-11-02 10:00:00 PST-0800
then day_ago
and yesterday
differ:
day_ago
is exactly 24 hours ago (relative to now
) but at 11 am, not at 10 am as now
yesterday
is yesterday at 10 am but it is 25 hours ago (relative to now
), not 24 hours.pendulum
module handles it automatically:
>>> import pendulum # $ pip install pendulum
>>> now = pendulum.create(2014, 11, 2, 10, tz='America/Los_Angeles')
>>> day_ago = now.subtract(hours=24) # exactly 24 hours ago
>>> yesterday = now.subtract(days=1) # yesterday at 10 am but it is 25 hours ago
>>> (now - day_ago).in_hours()
24
>>> (now - yesterday).in_hours()
25
>>> now
<Pendulum [2014-11-02T10:00:00-08:00]>
>>> day_ago
<Pendulum [2014-11-01T11:00:00-07:00]>
>>> yesterday
<Pendulum [2014-11-01T10:00:00-07:00]>

I know this is an old question, but I have a solution that isn't listed here.
When you produce the csv add a space after the comma but before your value e.g. , 005,
.
This worked to prevent auto date formatting in excel 2007 anyway .
Because otherwise, it would need an instance of the object to be executed. But it must be called from scratch, without constructing the object first, since it is usually the task of the main() function (bootstrap), to parse the arguments and construct the object, usually by using these arguments/program parameters.
Tried to do the solution with:
body {
overflow-y: scroll;
}
But I ended up with two scrollbars in Firefox in this case. So I recommend to use it on the html element like this:
html {
overflow-y: scroll;
}
Wow, this one took me a while to solve, as I was using SVN through Eclipse. In the end, the only thing that worked for me was to commit all non-affected files, then (with Eclipse closed) rename the project directory, and re-check the project out from SVN. Glad it works properly now!
ngKeypress
, ngKeydown
and ngKeyup
are now part of AngularJS.
<!-- you can, for example, specify an expression to evaluate -->
<input ng-keypress="count = count + 1" ng-init="count=0">
<!-- or call a controller/directive method and pass $event as parameter.
With access to $event you can now do stuff like
finding which key was pressed -->
<input ng-keypress="changed($event)">
Read more here:
https://docs.angularjs.org/api/ng/directive/ngKeypress https://docs.angularjs.org/api/ng/directive/ngKeydown https://docs.angularjs.org/api/ng/directive/ngKeyup
Earlier solutions:
Solution 1: Use ng-change
with ng-model
<input type="text" placeholder="+639178983214" ng-model="mobileNumber"
ng-controller="RegisterDataController" ng-change="keydown()">
JS:
function RegisterDataController($scope) {
$scope.keydown = function() {
/* validate $scope.mobileNumber here*/
};
}
Solution 2. Use $watch
<input type="text" placeholder="+639178983214" ng-model="mobileNumber"
ng-controller="RegisterDataController">
JS:
$scope.$watch("mobileNumber", function(newValue, oldValue) {
/* change noticed */
});
Virtual keyword for destructor is necessary when you want different destructors should follow proper order while objects is being deleted through base class pointer. for example:
Base *myObj = new Derived();
// Some code which is using myObj object
myObj->fun();
//Now delete the object
delete myObj ;
If your base class destructor is virtual then objects will be destructed in a order(firstly derived object then base ). If your base class destructor is NOT virtual then only base class object will get deleted(because pointer is of base class "Base *myObj"). So there will be memory leak for derived object.
Complete snippet would look like the following. It expands @mouad's answer to asserting on error's message (or generally str
representation of its args
), which may be useful.
from unittest import TestCase
class TestNoneTypeError(TestCase):
def setUp(self):
self.testListNone = None
def testListSlicing(self):
with self.assertRaises(TypeError) as ctx:
self.testListNone[:1]
self.assertEqual("'NoneType' object is not subscriptable", str(ctx.exception))
pip install module_name will work or If you are using a file that you were previously working on than just do shift+enter to reload and will do the job
Pls check JobScheduler for apis above 26
WakeLock was the best option for this but it is deprecated in api level 26
Pls check this link if you consider api levels above 26
https://developer.android.com/reference/android/support/v4/content/WakefulBroadcastReceiver.html#startWakefulService(android.content.Context,%20android.content.Intent)
It says
As of Android O, background check restrictions make this class no longer generally useful. (It is generally not safe to start a service from the receipt of a broadcast, because you don't have any guarantees that your app is in the foreground at this point and thus allowed to do so.) Instead, developers should use android.app.job.JobScheduler to schedule a job, and this does not require that the app hold a wake lock while doing so (the system will take care of holding a wake lock for the job).
so as it says cosider JobScheduler
https://developer.android.com/reference/android/app/job/JobScheduler
if it is to do something than to start and to keep it you can receive the broadcast ACTION_BOOT_COMPLETED
If it isn't about foreground pls check if an Accessibility service could do
another option is to start an activity from broadcast receiver and finish it after starting the service within onCreate() , since newer android versions doesnot allows starting services from receivers
I use this mnemonic :
a.compareTo(b) < 0 // a < b
a.compareTo(b) > 0 // a > b
a.compareTo(b) == 0 // a == b
You keep the signs and always compare the result of compareTo()
to 0
I search three places as shown below. Comments welcome.
public URL getResource(String resource){

return url;
}
}
//Let's now try with the classloader that loaded this class.
classLoader = Loader.class.getClassLoader();
if(classLoader != null){

if(url != null){
return url;
}
}
//Last ditch attempt. Get the resource from the classpath.

The absolute easiest way to stream a file into browser using ASP.NET MVC is this:
public ActionResult DownloadFile() {
return File(@"c:\path\to\somefile.pdf", "application/pdf", "Your Filename.pdf");
}
This is easier than the method suggested by @azarc3 since you don't even need to read the bytes.
Credit goes to: http://prideparrot.com/blog/archive/2012/8/uploading_and_returning_files#how_to_return_a_file_as_response
** Edit **
Apparently my 'answer' is the same as the OP's question. But I am not facing the problem he is having. Probably this was an issue with older version of ASP.NET MVC?
If, like me, you actually wanted to load .properties files from your filesystem instead of the classpath, but otherwise keep all the smarts related to lookup, then do the following:
java.util.ResourceBundle.Control
newBundle()
methodIn this silly example, I assume you have a folder at C:\temp
which contains a flat list of ".properties" files:
public class MyControl extends Control {
@Override
public ResourceBundle newBundle(String baseName, Locale locale, String format, ClassLoader loader, boolean reload)
throws IllegalAccessException, InstantiationException, IOException {
if (!format.equals("java.properties")) {
return null;
}
String bundleName = toBundleName(baseName, locale);
ResourceBundle bundle = null;
// A simple loading approach which ditches the package
// NOTE! This will require all your resource bundles to be uniquely named!
int lastPeriod = bundleName.lastIndexOf('.');
if (lastPeriod != -1) {
bundleName = bundleName.substring(lastPeriod + 1);
}
InputStreamReader reader = null;
FileInputStream fis = null;
try {
File file = new File("C:\\temp\\mybundles", bundleName);
if (file.isFile()) { // Also checks for existance
fis = new FileInputStream(file);
reader = new InputStreamReader(fis, Charset.forName("UTF-8"));
bundle = new PropertyResourceBundle(reader);
}
} finally {
IOUtils.closeQuietly(reader);
IOUtils.closeQuietly(fis);
}
return bundle;
}
}
Note also that this supports UTF-8, which I believe isn't supported by default otherwise.
To call the function you have to add ()
{this.renderIcon()}
You start by writing a class that derives from Attribute:
public class MyCustomAttribute: Attribute
{
public string SomeProperty { get; set; }
}
Then you could decorate anything (class, method, property, ...) with this attribute:
[MyCustomAttribute(SomeProperty = "foo bar")]
public class Foo
{
}
and finally you would use reflection to fetch it:
var customAttributes = (MyCustomAttribute[])typeof(Foo).GetCustomAttributes(typeof(MyCustomAttribute), true);
if (customAttributes.Length > 0)
{
var myAttribute = customAttributes[0];
string value = myAttribute.SomeProperty;
// TODO: Do something with the value
}
You could limit the target types to which this custom attribute could be applied using the AttributeUsage attribute:
/// <summary>
/// This attribute can only be applied to classes
/// </summary>
[AttributeUsage(AttributeTargets.Class)]
public class MyCustomAttribute : Attribute
Important things to know about attributes:
In the specific case above, you could do parent/child juggling.
$(this).parents("tr").children("td:first").text()
I had an outdated symlink that was preventing me from accessing the proper bin. I had also recently gone through a node upgrade which means a lot of my newer bins were available in a different folder with what i think was a lower priority
Here is what worked for me:
yarn -v
> 1.15.2
which yarn
> /Users/lfender/.yarn/bin/yarn
rm -rf /Users/lfender/.yarn/bin/yarn
npm uninstall --global yarn; npm install --global yarn
> + [email protected]
> added 1 package in 0.179s
which yarn
> /Users/lfender/.nvm/versions/node/v12.2.0/bin/yarn
yarn -v
> 1.16.0
If you are not using NVM, the location of your bin installs are likely to be unique to your system
From there, I've switched to doing yarn policies set-version
as outlined here https://stackoverflow.com/a/55278430/1426788 to define my yarn version at the repo level

I was struggling with this exact issue for three days. I had set permissions on the script to 755. I had been calling my script as follows.
<?php
$outcome = shell_exec('/tmp/clearUp.sh');
echo $outcome;
?>
My script was as follows.
#!bin/bash
find . -maxdepth 1 -name "search*.csv" -mmin +0 -exec rm {} \;
I was getting no output or feedback. The change I made to get the script to run was to add a cd to tmp inside the script:
#!bin/bash
cd /tmp;
find . -maxdepth 1 -name "search*.csv" -mmin +0 -exec rm {} \;
This was more by luck than judgement but it is now working perfectly. I hope this helps.
If you want True False
use:
"%s %s" % (True, False)
because str(True)
is 'True'
and str(False)
is 'False'
.
or if you want 1 0
use:
"%i %i" % (True, False)
because int(True)
is 1
and int(False)
is 0
.
Yes you can, with range
[docs]:
for i in range(1, len(l)):
# i is an integer, you can access the list element with l[i]
but if you are accessing the list elements anyway, it's more natural to iterate over them directly:
for element in l:
# element refers to the element in the list, i.e. it is the same as l[i]
If you want to skip the the first element, you can slice the list [tutorial]:
for element in l[1:]:
# ...
can you do another for loop inside this for loop
Sure you can.

Not certain what the HTML looks like (that would help with answers). If it's
<div class="testimonials content">stuff</div>
then simply remove the space in your css. A la...
.testimonials.content { css here }
UPDATE:
Okay, after seeing HTML see if this works...
.testimonials .wrapper .content { css here }
or just
.testimonials .wrapper { css here }
or
.desc-container .wrapper { css here }
all 3 should work.
I think everyone had the right idea, but all answers were not straightforward. I can see this being a very useful piece of code. Here is a snippet of what will work:
System.out.println(String.format("%.8f", EnterYourDoubleVariableHere));
the ".8"
is where you set the number of decimal places you would like to show.
I am using Eclipse and it worked no problem.
Hope this was helpful. I would appreciate any feedback!
I would recommend to use sftp, use this command sftp -oPort=7777 user@host
where -oPort is custom port number of ssh , in case if u changed it to 7777, then u can use -oPort, else if use only port 22 then plain sftp user@host
which asks for the password , then u can log in, and u can navigate to required location using cd /home/user
then a simple command get table
u can download it, If u want to download a directory/folder get -r someDirectory
will do it. If u want the file permissions also to exist then get -Pr someDirectory
.
For uploading on to remote change get to put in above commands.

Ok for all of you out there that arrived here in desperation searching for the same problem. I hope you will find this quicker then I did ;O.
This is how it is solved. JoostK told me at github that "the first argument to join is the table (or data) you're joining.". And he was right.
Here is the code. Different table and names but you will get the idea right? It t
DB::table('users')
->select('first_name', 'TotalCatches.*')
->join(DB::raw('(SELECT user_id, COUNT(user_id) TotalCatch,
DATEDIFF(NOW(), MIN(created_at)) Days,
COUNT(user_id)/DATEDIFF(NOW(), MIN(created_at))
CatchesPerDay FROM `catch-text` GROUP BY user_id)
TotalCatches'),
function($join)
{
$join->on('users.id', '=', 'TotalCatches.user_id');
})
->orderBy('TotalCatches.CatchesPerDay', 'DESC')
->get();
You need to be at MySQL version 5.6.4 or later to declare columns with fractional-second time datatypes. Not sure you have the right version? Try SELECT NOW(3)
. If you get an error, you don't have the right version.
For example, DATETIME(3)
will give you millisecond resolution in your timestamps, and TIMESTAMP(6)
will give you microsecond resolution on a *nix-style timestamp.
Read this: https://dev.mysql.com/doc/refman/8.0/en/fractional-seconds.html
NOW(3)
will give you the present time from your MySQL server's operating system with millisecond precision.
If you have a number of milliseconds since the Unix epoch, try this to get a DATETIME(3) value
FROM_UNIXTIME(ms * 0.001)
Javascript timestamps, for example, are represented in milliseconds since the Unix epoch.
(Notice that MySQL internal fractional arithmetic, like * 0.001
, is always handled as IEEE754 double precision floating point, so it's unlikely you'll lose precision before the Sun becomes a white dwarf star.)
If you're using an older version of MySQL and you need subsecond time precision, your best path is to upgrade. Anything else will force you into doing messy workarounds.
If, for some reason you can't upgrade, you could consider using BIGINT
or DOUBLE
columns to store Javascript timestamps as if they were numbers. FROM_UNIXTIME(col * 0.001)
will still work OK. If you need the current time to store in such a column, you could use UNIX_TIMESTAMP() * 1000
There are couple of way which can be used.
const stations = [
{call:'station one',frequency:'000'},
{call:'station two',frequency:'001'}
];
const callList = stations.map(({call}) => call)
Solution 1
<p>{callList.join(', ')}</p>
Solution 2
<ol>
{ callList && callList.map(item => <li>{item}</li>) }
</ol>
Of course there are other ways also available.

You can Choose 'Result to File' option in SSMS and export your select result to file and make your changes in result file and finally using BCP - Bulk copy you can insert in table 1 in database 2.

A good logic for your application could be something like:

]);
if ($request->hasFile('file')) {
$image = $request->file('file');
$name = time().'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('/storage/galeryImages/');
$image->move($destinationPath, $name);
$this->save();
return back()->with('success','Image Upload successfully');
}
}
Using an iframe
to "render" a PDF will not work on all browsers; it depends on how the browser handles PDF files. Some browsers (such as Firefox and Chrome) have a built-in PDF rendered which allows them to display the PDF inline where as some older browsers (perhaps older versions of IE attempt to download the file instead).
Instead, I recommend checking out PDFObject which is a Javascript library to embed PDFs in HTML files. It handles browser compatibility pretty well and will most likely work on IE8.
In your HTML, you could set up a div
to display the PDFs:
<div id="pdfRenderer"></div>
Then, you can have Javascript code to embed a PDF in that div
:
var pdf = new PDFObject({
url: "https://something.com/HTC_One_XL_User_Guide.pdf",
id: "pdfRendered",
pdfOpenParams: {
view: "FitH"
}
}).embed("pdfRenderer");

Since Java is a statically typed language, I would expect that a abs-method which takes an int returns an int, if it expects a float returns a float, for a Double, return a Double. Maybe it could return always the boxed or unboxed type for doubles and Doubles and so on.
So you need one method per type, but now you have a new problem: For byte, short, int, long the range for negative values is 1 bigger than for positive values.
So what should be returned for the method
byte abs (byte in) {
// @todo
}
If the user calls abs on -128? You could always return the next bigger type so that the range is guaranteed to fit to all possible input values. This will lead to problems for long, where no normal bigger type exists, and make the user always cast the value down after testing - maybe a hassle.
The second option is to throw an arithmetic exception. This will prevent casting and checking the return type for situations where the input is known to be limited, such that X.MIN_VALUE can't happen. Think of MONTH, represented as int.
byte abs (byte in) throws ArithmeticException {
if (in == Byte.MIN_VALUE) throw new ArithmeticException ("abs called on Byte.MIN_VALUE");
return (in < 0) ? (byte) -in : in;
}
The "let's ignore the rare cases of MIN_VALUE" habit is not an option. First make the code work - then make it fast. If the user needs a faster, but buggy solution, he should write it himself. The simplest solution that might work means: simple, but not too simple.
Since the code doesn't rely on state, the method can and should be made static. This allows for a quick test:
public static void main (String args []) {
System.out.println (abs(new Byte ( "7")));
System.out.println (abs(new Byte ("-7")));
System.out.println (abs((byte) 7));
System.out.println (abs((byte) -7));
System.out.println (abs(new Byte ( "127")));
try
{
System.out.println (abs(new Byte ("-128")));
}
catch (ArithmeticException ae)
{
System.out.println ("Integer: " + Math.abs (new Integer ("-128")));
}
System.out.println (abs((byte) 127));
System.out.println (abs((byte) -128));
}
I catch the first exception and let it run into the second, just for demonstration.
There is a bad habit in programming, which is that programmers care much more for fast than for correct code. What a pity!
If you're curious why there is one more negative than positive value, I have a diagram for you.
You must use %ld
to print a long int
, and %lld
to print a long long int
.
Note that only long long int
is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you're using).
You will also need to ensure that you use your compiler in a C99-compatible mode (for example, using the -std=gnu99
option to gcc). This is because the long long int
type was not introduced until C99; and although many compilers implement long long int
in C90 mode as an extension, the constant 2147483648
may have a type of unsigned int
or unsigned long
in C90. If this is the case in your implementation, then the value of -2147483648
will also have unsigned type and will therefore be positive, and the overall result will be not what you expect.

How To: Configure MachineKey in ASP.NET 2.0 - Web Farm Deployment Considerations
Web Farm Deployment Considerations
If you deploy your application in a Web farm, you must ensure that the configuration files on each server share the same value for validationKey and decryptionKey, which are used for hashing and decryption respectively. This is required because you cannot guarantee which server will handle successive requests.
With manually generated key values, the settings should be similar to the following example.
<machineKey validationKey="21F090935F6E49C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7 AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B" decryptionKey="ABAA84D7EC4BB56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F" validation="SHA1" decryption="AES" />
If you want to isolate your application from other applications on the same server, place the in the Web.config file for each application on each server in the farm. Ensure that you use separate key values for each application, but duplicate each application's keys across all servers in the farm.
In short, to set up the machine key refer the following link: Setting Up a Machine Key - Orchard Documentation.
Setting Up the Machine Key Using IIS Manager
If you have access to the IIS management console for the server where Orchard is installed, it is the easiest way to set-up a machine key.
Start the management console and then select the web site. Open the machine key configuration:
The machine key control panel has the following settings:
Uncheck "Automatically generate at runtime" for both the validation key and the decryption key.
Click "Generate Keys" under "Actions" on the right side of the panel.
Click "Apply".
and add the following line to the web.config
file in all the webservers
under system.web
tag if it does not exist.
<machineKey
validationKey="21F0SAMPLEKEY9C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7
AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B"
decryptionKey="ABAASAMPLEKEY56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F"
validation="SHA1"
decryption="AES"
/>
Please make sure that you have a permanent backup of the machine keys and web.config

return
in function return execution back to caller and exit
from function terminates the program.
in main
function return 0
or exit(0)
are same but if you write exit(0)
in different function then you program will exit from that position.
returning different values like return 1
or return -1
means that program is returning error .
When exit(0)
is used to exit from program, destructors for locally scoped non-static objects are not called. But destructors are called if return 0 is used.
compare()
will return false
(well, 0
) if the strings are equal.
So don't take exchanging one for the other lightly.

It is very difficult to validate Email correctly simply using HTML5 attribute "pattern". If you do not use a "pattern" someone@ will be processed. which is NOT valid email.
Using pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}"
will require the format to be [email protected]
however if the sender has a format like [email protected]
(or similar) will not be validated to fix this you could put pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}"
this will validate ".com.au or .net.au or alike.
However using this, it will not permit [email protected] to validate. So as far as simply using HTML5 to validate email addresses is still not totally with us. To Complete this you would use something like this:
<form>
<input id="email" type="text" name="email" pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" required placeholder="Enter you Email">
<br>
<input type="submit" value="Submit The Form">
</form>
or:
<form>
<input id="email" type="text" name="email" pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" required placeholder="Enter you Email">
<br>
<input type="submit" value="Submit The Form">
</form>
However, I do not know how to validate both or all versions of email addresses using HTML5 pattern attribute.
If you setup your select like the following:
<select ng-model="myselect" ng-options="b for b in options track by b"></select>

<option value="var3">var3</option>

The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)
Because of that where
clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.

This is not an error. This is a warning. The difference is pretty huge. This particular warning basically means that the <Context>
element in Tomcat's server.xml
contains an unknown attribute source
and that Tomcat doesn't know what to do with this attribute and therefore will ignore it.
Eclipse WTP adds a custom attribute source
to the project related <Context>
element in the server.xml
of Tomcat which identifies the source of the context (the actual project in the workspace which is deployed to the particular server). This way Eclipse can correlate the deployed webapplication with an project in the workspace. Since Tomcat version 6.0.16, any unspecified XML tags and attributes in the server.xml
will produce a warning during Tomcat's startup, even though there is no DTD nor XSD for server.xml
.
Just ignore it. Your web project is fine. It should run fine. This issue is completely unrelated to JSF.

Yes, you are correct. If you are using a jQuery plugin, do not put the code in the controller. Instead create a directive and put the code that you would normally have inside the link
function of the directive.
There are a couple of points in the documentation that you could take a look at. You can find them here:
Common Pitfalls
Ensure that when you are referencing the script in your view, you refer it last - after the angularjs library, controllers, services and filters are referenced.
EDIT: Rather than using $(element)
, you can make use of angular.element(element)

In Python2, print
was a keyword which introduced a statement:
print "Hi"
In Python3, print
is a function which may be invoked:
print ("Hi")
In both versions, %
is an operator which requires a string on the left-hand side and a value or a tuple of values or a mapping object (like dict
) on the right-hand side.
So, your line ought to look like this:
print("a=%d,b=%d" % (f(x,n),g(x,n)))
Also, the recommendation for Python3 and newer is to use {}
-style formatting instead of %
-style formatting:
print('a={:d}, b={:d}'.format(f(x,n),g(x,n)))
Python 3.6 introduces yet another string-formatting paradigm: f-strings.
print(f'a={f(x,n):d}, b={g(x,n):d}')
Joins can only be used when there is an association between entities. Your Employee entity should not have a field named id_team
, of type int
, mapped to a column. It should have a ManyToOne association with the Team entity, mapped as a JoinColumn:
@ManyToOne
@JoinColumn(name="ID_TEAM")
private Team team;
Then, the following query will work flawlessly:
select e from Employee e inner join e.team
Which will load all the employees, except those that aren't associated to any team.
The same goes for all the other fields which are a foreign key to some other table mapped as an entity, of course (id_boss
, id_profession
).
It's time for you to read the Hibernate documentation, because you missed an extremely important part of what it is and how it works.

The right command if you want to use a file with curl is this:
curl -XPOST 'http://jfblouvmlxecs01:9200/test/_doc/1' -d @lane.json
Elasticsearch is schemaless, therefore you don't necessarily need a mapping. If you send the json as it is and you use the default mapping, every field will be indexed and analyzed using the standard analyzer.
If you want to interact with Elasticsearch through the command line, you may want to have a look at the elasticshell which should be a little bit handier than curl.
2019-07-10: Should be noted that custom mapping types is deprecated and should not be used. I updated the type in the url above to make it easier to see which was the index and which was the type as having both named "test" was confusing.
document.all
is very old, you don't have to use it anymore.
To quote Nicholas Zakas:
For instance, when the DOM was young, not all browsers supported getElementById(), and so there was a lot of code that looked like this:

element = document.getElementById(id);
} else if (document.all) { //IE
element = document.all[id];
} else if (document.layers){ //Netscape < 6
element = document.layers[id];

Introducing constants into JavaScript is at best a hack.
A nice way of making persistent and globally accessible values in JavaScript would be declaring an object literal with some "read-only" properties like this:
my={get constant1(){return "constant 1"},
get constant2(){return "constant 2"},
get constant3(){return "constant 3"},
get constantN(){return "constant N"}
}
you'll have all your constants grouped in one single "my" accessory object where you can look for your stored values or anything else you may have decided to put there for that matter. Now let's test if it works:
my.constant1; >> "constant 1"
my.constant1 = "new constant 1";
my.constant1; >> "constant 1"
As we can see, the "my.constant1" property has preserved its original value. You've made yourself some nice 'green' temporary constants...
But of course this will only guard you from accidentally modifying, altering, nullifying, or emptying your property constant value with a direct access as in the given example.
Otherwise I still think that constants are for dummies. And I still think that exchanging your great freedom for a small corner of deceptive security is the worst trade possible.
One simple way to get all the queries you need is to use the data from information_schema and concat.
SELECT concat('CREATE TABLE new_db.', TABLE_NAME, ' LIKE old_db.', TABLE_NAME, ';') FROM `TABLES` WHERE TABLE_SCHEMA = 'old_db';
You'll then get a list of results that looks like this:
CREATE TABLE new_db.articles LIKE old_db.articles;
CREATE TABLE new_db.categories LIKE old_db.categories;
CREATE TABLE new_db.users LIKE old_db.users;
...
You can then just run those queries.
However it won't work with MySQL Views. You can avoid them by appending AND TABLE_TYPE = 'BASE TABLE'
from the initial query:
Facing the very same problem (avoiding the default path in a network) I came up to this solution with the hints given in other answers.
The solution is editing the Rprofile
file to overwrite the variable R_LIBS_USER
which by default points to the home directory.
Here the steps:
~\target
.Rprofile
file. In my case it was at C:\Program Files\R\R-3.3.3\library\base\R\Rprofile
.R_LIBS_USER
. In my case, I replaced the this line file.path(Sys.getenv("R_USER"), "R",
with file.path("~\target", "R",
.The documentation that support this solution is here
Original file with:
if(!nzchar(Sys.getenv("R_LIBS_USER")))
Sys.setenv(R_LIBS_USER=
file.path(Sys.getenv("R_USER"), "R",
"win-library",
paste(R.version$major,
sub("\\..*$", "", R.version$minor),
sep=".")
))
Modified file:
if(!nzchar(Sys.getenv("R_LIBS_USER")))
Sys.setenv(R_LIBS_USER=
file.path("~\target", "R",
"win-library",
paste(R.version$major,
sub("\\..*$", "", R.version$minor),
sep=".")
))
String[] result = input.split("(?!^)");
What this does is split the input String on all empty Strings that are not preceded by the beginning of the String.
Yes, you can always use null
instead of an object. Just be careful because some methods might throw error.
It would be 1.
also null
s would be factored in in the for loop, but you could use
for(Item i : itemList) {
if (i!= null) {
//code here
}
}
Null is similar to zero pointer in C++. So it is a reference which not pointing to any value.
DBNull.Value
is completely different and is a constant which is returned when a field value contains NULL.

Using only "native" Windows utilities, try the following, where "516" is the process ID that you want the image name for:
for /f "delims=," %a in ( 'tasklist /fi "PID eq 516" /nh /fo:csv' ) do ( echo %~a )
for /f %a in ( 'tasklist /fi "PID eq 516" ^| findstr "516"' ) do ( echo %a )
Or you could use wmic (the Windows Management Instrumentation Command-line tool) and get the full path to the executable:
wmic process where processId=516 get name
wmic process where processId=516 get ExecutablePath
Or you could download Microsoft PsTools, or specifically download just the pslist utility, and use PsList:
for /f %a in ( 'pslist 516 ^| findstr "516"' ) do ( echo %a )
!foo.dll
in .gitignore, or (every time!) git add -f foo.dll
I don't think execute
git rm first_file.txt
is a good idea.
when git notice your files is unmerged, you should ensure you had committed it.
And then open the conflict file:
cat first_file.txt
fix the conflict
4.
git add file
git commit -m "fix conflict"
5.
git push
it should works for you.
A regex is good for matching the general format but I think you should move parsing to the Date class, e.g.:
function parseDate(str) {
var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/);
return (m) ? new Date(m[3], m[2]-1, m[1]) : null;
}
Now you can use this function to check for valid dates; however, if you need to actually validate without rolling (e.g. "31/2/2010" doesn't automatically roll to "3/3/2010") then you've got another problem.
[Edit] If you also want to validate without rolling then you could add a check to compare against the original string to make sure it is the same date:
function parseDate(str) {
var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)
, d = (m) ? new Date(m[3], m[2]-1, m[1]) : null
, nonRolling = (d&&(str==[d.getDate(),d.getMonth()+1,d.getFullYear()].join('/')));
return (nonRolling) ? d : null;
}
[Edit2] If you want to match against zero-padded dates (e.g. "08/08/2013") then you could do something like this:
function parseDate(str) {
function pad(x){return (((''+x).length==2) ? '' : '0') + x; }
var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)
, d = (m) ? new Date(m[3], m[2]-1, m[1]) : null
, matchesPadded = (d&&(str==[pad(d.getDate()),pad(d.getMonth()+1),d.getFullYear()].join('/')))
, matchesNonPadded = (d&&(str==[d.getDate(),d.getMonth()+1,d.getFullYear()].join('/')));
return (matchesPadded || matchesNonPadded) ? d : null;
}
However, it will still fail for inconsistently padded dates (e.g. "8/08/2013").
Using following sample code we can filter array in angular controller by name. this is based on following description. http://docs.angularjs.org/guide/filter
this.filteredArray = filterFilter(this.array, {name:'Igor'});
JS:
angular.module('FilterInControllerModule', []).
controller('FilterController', ['filterFilter', function(filterFilter) {
this.array = [
{name: 'Tobias'},
{name: 'Jeff'},
{name: 'Brian'},
{name: 'Igor'},
{name: 'James'},
{name: 'Brad'}
];
this.filteredArray = filterFilter(this.array, {name:'Igor'});
}]);

Try the following:
INSERT INTO table1
SELECT 'A string', 5, idTable2 idTable2 FROM table2 WHERE ...
Use window.open()
:
var win = window.open('http://stackoverflow.com/', '_blank');
if (win) {
//Browser has allowed it to be opened
win.focus();
} else {
//Browser has blocked it
alert('Please allow popups for this website');
}
Depending on the browsers implementation this will work
There is nothing you can do to make it open in a window rather than a tab.
Above provided answer is good for extracting single property, what if you want to extract more than one property from array of objects. Here is the solution!! In case of that we can simply use _.pick(object, [paths])
_.pick(object, [paths])
Lets assume objArray has objects with three properties like below
objArray = [ { foo: 1, bar: 2, car:10}, { foo: 3, bar: 4, car:10}, { foo: 5, bar: 6, car:10} ];
Now we want to extract foo and bar property from every object and store them in a separate array. First we will iterate array elements using map and then we apply Lodash Library Standard _.pick() method on it.
Now we are able to extract 'foo' and 'bar' property.
var newArray = objArray.map((element)=>{ return _.pick(element, ['foo','bar'])})
console.log(newArray);
and result would be [{foo: 1, bar: 2},{foo: 3, bar: 4},{foo: 5, bar: 6}]
enjoy!!!

If you want deep validation like @speculees, here's an answer using deep-keys
(disclosure: I'm sort of a maintainer of this small package)
// obj1 should have all of obj2's properties
var deepKeys = require('deep-keys');
var _ = require('underscore');
assert(0 === _.difference(deepKeys(obj2), deepKeys(obj1)).length);
// obj1 should have exactly obj2's properties
var deepKeys = require('deep-keys');
var _ = require('lodash');
assert(0 === _.xor(deepKeys(obj2), deepKeys(obj1)).length);
or with chai
:
var expect = require('chai').expect;
var deepKeys = require('deep-keys');
// obj1 should have all of obj2's properties
expect(deepKeys(obj1)).to.include.members(deepKeys(obj2));
// obj1 should have exactly obj2's properties
expect(deepKeys(obj1)).to.have.members(deepKeys(obj2));
It seems like you can also use the patch command. Put the diff in the root of the repository and run patch
from the command line.
patch -i yourcoworkers.diff
or
patch -p0 -i yourcoworkers.diff
You may need to remove the leading folder structure if they created the diff without using --no-prefix
.
If so, then you can remove the parts of the folder that don't apply using:
patch -p1 -i yourcoworkers.diff
The -p(n) signifies how many parts of the folder structure to remove.
More information on creating and applying patches here.
You can also use
git apply yourcoworkers.diff --stat
to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).
Mine got solved by:
You get one for free, called ROWID. This is in every SQLite table whether you ask for it or not.
If you include a column of type INTEGER PRIMARY KEY, that column points at (is an alias for) the automatic ROWID column.
ROWID (by whatever name you call it) is assigned a value whenever you INSERT a row, as you would expect. If you explicitly assign a non-NULL value on INSERT, it will get that specified value instead of the auto-increment. If you explicitly assign a value of NULL on INSERT, it will get the next auto-increment value.
Also, you should try to avoid:
INSERT INTO people VALUES ("John", "Smith");
and use
INSERT INTO people (first_name, last_name) VALUES ("John", "Smith");
instead. The first version is very fragile — if you ever add, move, or delete columns in your table definition the INSERT will either fail or produce incorrect data (with the values in the wrong columns).
My issue was simple: the Master page and Master.Designer.cs class had the correct Namespace, but the Master.cs class had the wrong namespace.
It usually happens to me when I misspell android - I just type andorid or alike, and it's not obvious at first sight especially after many hours of programming, so I just do a search for "android" one by one and see if search skips one tag - if it does then I have a close look and I see where was typo.
I don't know why, but for some reason, the "/bin/bash" version didn't work for me. Instead, the simpler version worked, following the example given here at Oracle Docs.
String[] args = new String[] {"ping", "www.google.com"};
Process proc = new ProcessBuilder(args).start();
Font myFont = new Font("Serif", Font.BOLD, 12);
, then use a setFont method on your components like
JButton b = new JButton("Hello World");
b.setFont(myFont);
As mentioned above you can wait for active connections to get closed:
private static void WaitForReady() {
WebDriverWait wait = new WebDriverWait(webDriver, waitForElement);
wait.Until(driver => (bool)((IJavaScriptExecutor)driver).ExecuteScript("return jQuery.active == 0"));
}
My observation is this is not reliable as data transfer happens very quickly. Much more time is consumed on data processing and rendering on the page and even jQuery.active == 0
data might not be yet on the page.
Much wiser is to use an explicit wait for element to be shown on the page, see some of the answers related to this.
The best situation is if your web application have some custom loader or indication that data is being processed. In this case you can just wait for this indication to hide.
You can use an ExecutorCompletionService. The documentation even has an example for your exact use-case:
Suppose instead that you would like to use the first non-null result of the set of tasks, ignoring any that encounter exceptions, and cancelling all other tasks when the first one is ready:
void solve(Executor e, Collection<Callable<Result>> solvers) throws InterruptedException {
CompletionService<Result> ecs = new ExecutorCompletionService<Result>(e);
int n = solvers.size();
List<Future<Result>> futures = new ArrayList<Future<Result>>(n);
Result result = null;
try {
for (Callable<Result> s : solvers)
futures.add(ecs.submit(s));
for (int i = 0; i < n; ++i) {
try {
Result r = ecs.take().get();
if (r != null) {
result = r;
break;
}
} catch (ExecutionException ignore) {
}
}
} finally {
for (Future<Result> f : futures)
f.cancel(true);
}
if (result != null)
use(result);
}
The important thing to notice here is that ecs.take() will get the first completed task, not just the first submitted one. Thus you should get them in the order of finishing the execution (or throwing an exception).
In Ubuntu 18.04 the QtCreator examples and API docs missing, This is my way to solve this problem, should apply to almost every Ubuntu release.
For QtCreator and Examples and API Docs:
sudo apt install `apt-cache search 5-examples | grep qt | grep example | awk '{print $1 }' | xargs `
sudo apt install `apt-cache search 5-doc | grep "Qt 5 " | awk '{print $1}' | xargs`
sudo apt-get install build-essential qtcreator qt5-default
If something is also missing, then:
sudo apt install `apt-cache search qt | grep 5- | grep ^qt | awk '{print $1}' | xargs `
Hope to be helpful.

use this code create xml file in drawable folder name:button
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item

for those like me still stuck with SQL Server 2000, SET ROWCOUNT {number};
can be used before the UPDATE
query
SET ROWCOUNT 100;
UPDATE Table SET ..;
SET ROWCOUNT 0;
will limit the update to 100 rows
It has been deprecated at least since SQL 2005, but as of SQL 2017 it still works. https://docs.microsoft.com/en-us/sql/t-sql/statements/set-rowcount-transact-sql?view=sql-server-2017
You should use LayoutParams
to set your button margins:
LayoutParams params = new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT
);
params.setMargins(left, top, right, bottom);
yourbutton.setLayoutParams(params);
Depending on what layout you're using you should use RelativeLayout.LayoutParams
or LinearLayout.LayoutParams
.
And to convert your dp measure to pixel, try this:
Resources r = mContext.getResources();
int px = (int) TypedValue.applyDimension(
TypedValue.COMPLEX_UNIT_DIP,
yourdpmeasure,
r.getDisplayMetrics()
);
If you have WinWord, you can copy what you need into that, touch up the results, and then paste that into Confluence. I've found that easier than the other solutions here.
For this you can simply use the "HttpWebRequest" and "HttpWebResponse" classes in .net.
Below is a sample console app I wrote to demonstrate how easy this is.
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Test
{
class Program
{
static void Main(string[] args)
{
string url = "www.somewhere.com";
string fileName = @"C:\output.file";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Timeout = 5000;
try
{
using (WebResponse response = (HttpWebResponse)request.GetResponse())
{
using (FileStream stream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
{
byte[] bytes = ReadFully(response.GetResponseStream());
stream.Write(bytes, 0, bytes.Length);
}
}
}
catch (WebException)
{
Console.WriteLine("Error Occured");
}
}
public static byte[] ReadFully(Stream input)
{
byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
}
}
Enjoy!
For a cross browser implementation I'd sugguest you look at prototype.js $A
function
function $A(iterable) {
if (!iterable) return [];
if ('toArray' in Object(iterable)) return iterable.toArray();
var length = iterable.length || 0, results = new Array(length);
while (length--) results[length] = iterable[length];
return results;
}
It doesn't use Array.prototype.slice
probably because it isn't available on every browser. I'm afraid the performance is pretty bad as there a the fall back is a javascript loop over the iterable
.
#include<iostream>
#include<conio.h>
#include<string.h>
using namespace std;
int main()
{
char str[80];
int i;
cout<<"\n enter string:";
cin.getline(str,80);
int n=strlen(str);
cout<<"\n lenght is:"<<n;
getch();
return 0;
}
This is the program if you want to use strlen . Hope this helps!
The more_itertools
project extends itertools.islice
to handle negative indices.
Example
import more_itertools as mit
iterable = 'ABCDEFGH'
list(mit.islice_extended(iterable, 1, -1))
# Out: ['B', 'C', 'D', 'E', 'F', 'G']
Therefore, you can elegantly apply it slice elements between the first and last items of an iterable:
for car in mit.islice_extended(cars, 1, -1):
# do something
I struggled to understand the proxy settings for websockets for https therefore let me put clarity here what i realized.
First you need to enable proxy
and proxy_wstunnel
apache modules and the apache configuration file will look like this.
<IfModule mod_ssl.c>
<VirtualHost _default_:443>
ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/your_project_public_folder
SSLEngine on
SSLCertificateFile /etc/ssl/certs/path_to_your_ssl_certificate
SSLCertificateKeyFile /etc/ssl/private/path_to_your_ssl_key
<Directory /var/www/your_project_public_folder>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
php_flag display_errors On
</Directory>
ProxyRequests Off
ProxyPass /wss/ ws://example.com:port_no
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
</IfModule>
in your frontend application use the url "wss://example.com/wss/"
this is very important mostly if you are stuck with websockets you might be making mistake in the front end url. You probably putting url wrongly like below.
wss://example.com:8080/wss/ -> port no should not be mentioned
ws://example.com/wss/ -> url should start with wss only.
wss://example.com/wss -> url should end with / -> most important
also interesting part is the last /wss/
is same as proxypass
value if you writing proxypass /ws/
then in the front end you should write /ws/
in the end of url.
Create the below function
Alter FUNCTION InitialCap(@String VARCHAR(8000))
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE @Position INT;
SELECT @String = STUFF(LOWER(@String),1,1,UPPER(LEFT(@String,1))) COLLATE Latin1_General_Bin,
@Position = PATINDEX('%[^A-Za-z''][a-z]%',@String COLLATE Latin1_General_Bin);
WHILE @Position > 0
SELECT @String = STUFF(@String,@Position,2,UPPER(SUBSTRING(@String,@Position,2))) COLLATE Latin1_General_Bin,
@Position = PATINDEX('%[^A-Za-z''][a-z]%',@String COLLATE Latin1_General_Bin);
RETURN @String;
END ;
Then call it like
select dbo.InitialCap(columnname) from yourtable
The facade is another Request class, access it with the full path:
$input = \Request::all();
From laravel 5 you can also access it through the request()
function:
$input = request()->all();
you have to iterate gridview Rows
for (int count = 0; count < grd.Rows.Count; count++)
{
if (((CheckBox)grd.Rows[count].FindControl("yourCheckboxID")).Checked)
{
((Label)grd.Rows[count].FindControl("labelID")).Text
}
}
In CSS, for the font-weight
property, the value: normal
defaults to the numeric value 400, and bold
to 700.
If you want to specify other weights, you need to give the number value. That number value needs to be supported for the font family that you are using.
For example you would define semi-bold like this:
font-weight: 600;
Here an JSFiddle using 'Open Sans' font family, loaded with the above weights.
We can control tab size by file type with EditorConfig and its EditorConfig for VS Code extension. We then can make Alt + Shift + F specific to each file type.
Open the VS Code command palette with CTRL + P and paste this:
ext install EditorConfig
[*]
indent_style = space
[*.{js,ts,json}]
indent_size = 2
[*.java]
indent_size = 4
[*.go]
indent_style = tab
EditorConfig overrides whatever settings.json configures for the editor. There is no need to change editor.detectIndentation
.
As Nikolai has said you can use the gdb 'set' command to change the value of a variable.
You can also use the 'set' command to change memory locations. eg. Expanding on Nikolai's example:
(gdb) l
6 {
7 int i;
8 struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10
(gdb) p &i
$2 = (int *) 0xbfbb0000
(gdb) set *((int *) 0xbfbb0000) = 20
(gdb) p i
$3 = 20
This should work for any valid pointer, and can be cast to any appropriate data type.
For me none of earlier answer works. I did need to convert my static class to enum. Like this:
export enum MyConstants {
MyFirstConstant = 'MyFirstConstant',
MySecondConstant = 'MySecondConstant'
}
Then in my component I add new property as suggested in other answers
export class MyComponent {
public MY_CONTANTS = MyConstans;
constructor() { }
}
Then in my component's template I use it this way
<div [myDirective]="MY_CONTANTS.MyFirstConstant"> </div>
EDIT: Sorry. My problem was different than OP's. I still leave this here if someelse have same problem than I.
ASP.NET 2 and SQL Server reporting services 2005 have a limit of 2028. I found this out the hard way, where my dynamic URL generator would not pass over some parameters to a report beyond that point. This was under Internet Explorer 8.
If you don't want to use call back then you can Use "Q" module.
For example:
function getdb() {
var deferred = Q.defer();
MongoClient.connect(databaseUrl, function(err, db) {
if (err) {
console.log("Problem connecting database");
deferred.reject(new Error(err));
} else {
var collection = db.collection("url");
deferred.resolve(collection);
}
});
return deferred.promise;
}
getdb().then(function(collection) {
// This function will be called afte getdb() will be executed.
}).fail(function(err){
// If Error accrued.
});

Here is a quick DOM example that shows how to read and write a simple xml file with its dtd:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE roles SYSTEM "roles.dtd">
<roles>
<role1>User</role1>
<role2>Author</role2>
<role3>Admin</role3>

<!ELEMENT roles (role1,role2,role3,role4)>
<!ELEMENT role1 (#PCDATA)>
<!ELEMENT role2 (#PCDATA)>
<!ELEMENT role3 (#PCDATA)>

First import these:
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import org.xml.sax.*;
import org.w3c.dom.*;
Here are a few variables you will need:
private String role1 = null;
private String role2 = null;
private String role3 = null;
private String role4 = null;
private ArrayList<String> rolev;
Here is a reader (String xml is the name of your xml file):
public boolean readXML(String xml) {
rolev = new ArrayList<String>();
Document dom;
// Make an instance of the DocumentBuilderFactory
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try {
// use the factory to take an instance of the document builder
DocumentBuilder db = dbf.newDocumentBuilder();
// parse using the builder to get the DOM mapping of the
// XML file
dom = db.parse(xml);
Element doc = dom.getDocumentElement();
role1 = getTextValue(role1, doc, "role1");
if (role1 != null) {
if (!role1.isEmpty())
rolev.add(role1);
}
role2 = getTextValue(role2, doc, "role2");
if (role2 != null) {

rolev.add(role2);
}
role3 = getTextValue(role3, doc, "role3");
if (role3 != null) {

getTextValue is here:

String value = def;
NodeList nl;
nl = doc.getElementsByTagName(tag);
if (nl.getLength() > 0 && nl.item(0).hasChildNodes()) {

}
Add a few accessors and mutators and you are done!
The first one catches all subclasses of Throwable
(this includes Exception
and Error
), the second one catches all subclasses of Exception
.
Error
is programmatically unrecoverable in any way and is usually not to be caught, except for logging purposes (which passes it through again). Exception
is programmatically recoverable. Its subclass RuntimeException
indicates a programming error and is usually not to be caught as well.
Since some of the answers are outdated, I would like to provide my own -
To integrate ZXing library into your Android app as suggested by their Wiki, you need to add 2 Java files to your project:
Then in Android Studio add the following line to build.gradle file:
dependencies {
....
compile 'com.google.zxing:core:3.2.1'
}
Or if still using Eclipse with ADT-plugin add core.jar file to the libs subdirectory of your project (here fullscreen Windows and fullscreen Mac):
Finally add this code to your MainActivity.java:
public void scanQRCode(View v) {
IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
integrator.initiateScan(IntentIntegrator.QR_CODE_TYPES);
